Bug ID: 21035
Summary: longjmp() resets FPU exception mask
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: nyh at math dot technion.ac.il
Target Milestone: ---
Created attachment 9745
--> https://sourceware.org/bugzilla/attachment.cgi?id=9745&action=edit
Code demonstrating this problem (C++)
I wrote a small test for feenablexcept() which enables an FPU exception (e.g.,
FE_DIVBYZERO), makes it happen (dividing 1.0 by 0.0), catches the exception,
and longjmp()s to return from the test. See code below.
However, it turns out that longjmp(), very unexpectedly, resets the exception
mask back to zero! So after an feenableexcept() we'll get one exception and
longjmp, but a second division by zero will no longer generate a signal.
Code demonstrating this problem attached.

locale/programs/linereader.c has the code:
while (isdigit (ch = lr_getc (lr)))
{
lr->token.val.num *= 10;
lr->token.val.num += ch - '0';
}
There is no check for the multiplication or addition overflowing unsigned long
int (the type of num). Then, when such tokens are used later, the value is
often stored in smaller fields, again without checks for overflow.

this is from posix:
The freopen() function shall first attempt to flush the stream associated with
stream as if by a call to fflush(stream).
this is from c99 7.19.5.4:
The freopen function first attempts to close any file that is associated with
the specified stream.
by my understanding of the standards, i think this code should print new
#include <stdio.h>
int main() {
size_t s;
char *p = "old";
FILE *f = open_memstream(&p, &s);
fputs("new", f);
freopen("some_file", "r", f);
puts(p);
}
openbsd and musl print new

Just a note: stack frame pointer is stored in %ebp, not %ebx.

--- Comment #10 from Torvald Riegel <triegel at redhat dot com> ---
The new condition variable does not use custom assembly code anymore but uses
the generic syscall implementation (through that being used in the Linux futex
wrappers), which should use sysenter if that's available. Thus, this should be
fixed.

I don't understand what exactly you are looking for.
It seems you could just use POSIX' process-shared mutexes and condition
variables, which are supported by glibc. If this is not what you are looking
for, then please reopen this bug and explain in detail what enhancement you'd
like to see.

--- Comment #56 from Torvald Riegel <triegel at redhat dot com> ---
The new condition variable implementation is now committed upstream. It should
be the base for any improvement suggestions from now on.
How to support PI for condvars has also been discussed at the Linux Real-Time
Summit 2016:
https://wiki.linuxfoundation.org/realtime/events/rt-summit2016/schedule
So far, there is no known solution for how to achieve PI support given the
current constraints we have (eg, available futex operations, POSIX
requirements, ...).

--- Comment #2 from Dima Tisnek <dimaqq at gmail dot com> ---
What I was looking for was using same condition variable from two processes
that don't have a parent-child relationship.
There's a solution at http://stackoverflow.com/a/35511763/705086 that uses
pthread_xxx primitives with PTHREAD_PROCESS_SHARED flag on a mmap()ed region.
I was hoping to use futex primitives more directly, but sheer number of corner
cases makes that impractical.

commit 436cfba0abf749e5993b52dce589bae482f8c58a
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Jan 11 13:59:01 2017 +0000
Fix ld-address format-truncation error.
With the elf/sotruss-lib.c failure fixed, building 64-bit glibc with
GCC mainline fails with another format-truncation error in
locale/programs/ld-address.c, where 11 bytes are allocated for a
buffer to print a long int value.
This patch changes that code to allocate 21 bytes. Treating this
value as signed is questionable and I don't think large values are
actually useful here, but I think those can be considered as instances
of bug 21036 which I've filed for overflow checks for numeric values
in localedef in general, and don't need to be addressed to fix the
build.
Tested with GCC mainline with compilation for aarch64 with
build-many-glibcs.py, and with glibc testsuite for x86_64 (built with
GCC 6).
(Note that while this fixes the build of 64-bit glibc with GCC
mainline, further fixes will be needed to get the testsuite building
with GCC mainline again.)
* locale/programs/ld-address.c (INT_STR_ELEM): Increase size of
buffer used to print long int value.

I can't reproduce this on x86_64 RHEL7 (old condvar algorithm). The new
condvar algorithm doesn't use requeue, so it should also not be affected.
Therefore, I'll close this bug.

The use of pthread_cond_wait is still wrong, because you expect it wake-ups to
reveal an ordering -- but spurious wake-ups are allowed. In the general case,
you should always put pthread_cond_wait in a loop and check an actual flag that
is set before pthread_cond_signal is called. Otherwise, you are just using the
condvar to optimize how you wait.

In your test case (and ignoring spurious wake-ups), both C and D start to wait
on the condvar before the signal is issued. Thus, they are both eligible to
consume the signal, as is A (C and D enter the barrier while having acquired
cs_lock, and B acquires the cs_lock after it exits from both barriers; C and D
release cs_lock atomically with starting to wait on cs_cond; B signals after
having acquired cs_lock, so C and D waiting happens before B's signal).
Therefore, I'm closing this as invalid (because the test complains about
correct behavior).
The new condvar that is now committed upstream fixes all the bugs we are aware
of (see Bug 13165).

commit 6a1cefac196f45d766027c97a6c8c44459c9cccd
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Jan 11 15:28:08 2017 +0000
Make endian-conversion macros always return correct types (bug 16458).
Bug 16458 reports that the endian-conversion macros in <endian.h> and
<netinet/in.h>, in the case where no endian conversion is needed, just
return their arguments without converting to the expected return type,
so failing to act as expected for a macro version of a function. (The
<netinet/in.h> macros, in particular, are described with prototypes in
POSIX so should act like correspondingly prototyped functions.)
Where previously this was a fairly obscure issue, it now results in
glibc build with GCC mainline breaking for big-endian systems:
nss_hesiod/hesiod-service.c: In function '_nss_hesiod_getservbyport_r':
nss_hesiod/hesiod-service.c:142:39: error: '%d' directive output may be
truncated writing between 1 and 11 bytes into a region of size 6
[-Werror=format-truncation=]
snprintf (portstr, sizeof portstr, "%d", ntohs (port));
^~
nss_hesiod/hesiod-service.c:142:38: note: using the range [1, -2147483648]
for directive argument
snprintf (portstr, sizeof portstr, "%d", ntohs (port));
^~~~
nss_hesiod/hesiod-service.c:142:3: note: format output between 2 and 12
bytes into a destination of size 6
snprintf (portstr, sizeof portstr, "%d", ntohs (port));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The port argument is passed as int to this function, so when ntohs
does not convert the compiler cannot tell that the result is within
the range of uint16_t. (I don't know if in fact it's possible for
out-of-range values to reach this function and so get truncated as
strings without this patch or as integers with it.)
This patch arranges for these macros to use identity functions to
ensure appropriate conversions while having warnings for implicit
conversions of function arguments that might not occur with a cast.
Tested for x86_64 and x86; with build-many-glibcs.py with GCC 6; and
with build-many-glibcs.py with GCC mainline for powerpc to test the
build fix.

The new condvar doesn't use futex-requeue anymore, so closing this is okay.
Adhemerval, it might still be good to fix the _ASSUME* problem that you
described though. I currently don't see a need for requeue elsewhere, but I
wouldn't like to forget about this problem either. If you agree, could you
open a separate bug for it?

--- Comment #13 from Torvald Riegel <triegel at redhat dot com> ---
A new condition variable implementation has been committed, which as different
performance properties.
The statements made in comment #9 do not really consider what is actually going
on (e.g., waking another thread does not generally require the kernel to
context switch to it immediately; not being able to acquire a mutex does not
mean the respective thread has to block using futexes right away; the scenario
plays out differently on a multiprocessor that is not oversubscribed; ...).
The new condition variable implementation contains code comments that discuss
related aspects in some more detail.
Therefore, I'm closing this bug. If you observe a potential performance
problem with the new condition variable, please open a new bug.

--- Comment #17 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
I am not sure if we really need to keep track of the
__ASSUME_{REQUEUE_PI,FUTEX_LOCK_PI}. The __ASSUME_FUTEX_LOCK_PI was just
removed and __ASSUME_REQUEUE_PI is not really used anymore and I think we can
just remove its definition for every architecture. It is used only for
USE_REQUEUE_PI in nptl/pthreadP.h and the macro is not use in any place.

You're right. Just removing is the easiest option.

--- Comment #3 from Torvald Riegel <triegel at redhat dot com> ---
I do not think that pthread_cond_timedwait is meant to be used with absolute
timeouts that have already expired. The intent is to actually wait for a
condition. If timeouts are extremely short (or expired), then the typical
usage pattern of a pthread_cond_timedwait essentially becomes busy-waiting by
constantly acquiring and releasing the associated mutex. This is not what
condition variables are intended for.
Adding the clock_gettime call as a check can reduce wake-up latency in other
scenarios (by the amount of time required to perform the clock_gettime call);
thus, the proposed change would not be a clear performance win generally.
Also, if programs have extremely short or potentially expired timeouts, they
can easily run clock_gettime themselves in the critical section before calling
pthread_cond_timedwait.
Thus, I'm closing this as WONTFIX.

Bug ID: 21041
Summary: Fix for bug 20019 causes linker errors for shared
libraries using longjmp
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: pb at pbcl dot net
Target Milestone: ---
The recent patch for bug 20019 causes an unfortunate effect when a shared
library that calls longjmp (but does not use libpthread) is linked into a
program that links -lpthread.
As a slight variation on the testcase for that bug:
$ cat main.c
void foo (void);
int
main ()
{
foo ();
return 0;
}
$ cat foo.c
void bar (void *dst, void *src);
void
foo (void)
{
char dst[50];
char src[50];
bar (dst, src);
}
$ cat bar.c
#include <setjmp.h>
void
bar (void *dst, void *src)
{
jmp_buf j;
longjmp(j,1);
}
$ gcc -O2 -c -o main.o main.c
$ gcc -O2 -fPIC -c -o foo.o foo.c
$ gcc -O2 -fPIC -c -o bar.o bar.c
$ ld.gold -shared -z now -o libbar.so bar.o
$ ld.gold -shared -z now -o libfoo.so foo.o libbar.so
$ gcc -o foo main.o libfoo.so -Wl,-rpath,. -lpthread
$ ./foo
./foo: Relink `./libbar.so' with `libpthread.so.0' for IFUNC symbol `longjmp'

x86_64, libc 2.24 (on Fedora 25).
Maybe this is related to the similar issue #12420 ?

This has been fixed back in July 2014 in commit

been part of the 2.20 release (I haven't checked the release tarball to confirm
this though), so I'm adjusting the Version field as well.

--- Comment #1 from Torvald Riegel <triegel at redhat dot com> ---
In the test case, a thread that has acquired a non-robust mutex terminates.
glibc currently assumes that what happens in such a case is undefined behavior;
thus, both not being able to acquire the mutex (e.g., as in main() in the test
case) as well as glibc-internal inconsistencies (ie, the assertion that fails)
are not a bug.
POSIX seems to want the mutex to remain acquired by some imaginary thread
(because the thread that had acquired it does not exist anymore, arguably), but
they do not seem to have considered the implementation complexity this would
result in and the potential runtime overheads.
This difference between current glibc and POSIX is tracked in Bug 17463. I
think glibc will continue to treat this as undefined behavior, which is why I'm
marking this bug as a duplicate of Bug 17463.

I don't think it is required to preserve objects on the stack of threads that
have not been re-created in the child after fork(). POSIX states that only one
thread will exist in the forked child. This seems equivalent to saying that
all threads are duplicated in the child, but all child but the one that is the
duplicate of the parent thread that called fork() are terminated before that
remaining child thread continues execution. Given that objects on stacks of
terminated threads are not required to be preserved either, I think this is not
a bug. Please close this bug if you agree with this reasoning.

--- Comment #2 from Florian Weimer <fweimer at redhat dot com> ---
POSIX says:
“If a multi-threaded process calls fork(), the new process shall contain a
replica of the calling thread and its entire address spaceâ€
This suggests to me that other thread stacks and TLS variables need to be
preserved because they are part of the address space as well (at least if the
addresses of these objects have been taken and published in some way to the
current thread).

--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Note that it's only glibc's job to ensure that longjmp doesn't change the
mask - that is, that when setjmp returns for the second time, the
floating-point environment is the same as it was on entry to longjmp. If
it's the kernel or processor changing the mask on entry to a signal
handler, that's not glibc's problem.

I don't know the status in the kernel, but presumably we'd keep it open
until the buggy kernel versions are no longer supported or we've decided
not to work around the kernel bug.

You are correct. I missed that at the time the signal handler is called, the
mask is already reset, and I wrongly suspected the longjmp was doing that.
Sorry about that.

--- Comment #5 from Nadav Har'El <nyh at math dot technion.ac.il> ---
Hmm, on second thought, I think this actually *is* a sigsetjmp()/siglongjmp()
problem:
If I understand correctly, when the kernel starts a signal handler, it saves
the FPU state (including the control word) and then sets some "sane default" so
the handler can run without having to guess what kind of messed up state the
application was in when the signal occurred. I'm guessing this "sane default"
probably has all the FPU exceptions masked, because this is what FNINIT does by
default.
If this is what happens, then sigsetjmp/siglongjmp needs to save the FPU state
- including the control word - as they were during the time of sigsetjmp. If
they don't, instead of restoring the correct fpu control word, we'll be left
with the "sane default" that the signal handler left us with.
Apparently this issue has been known for many years: see for example:
https://bugs.openjdk.java.net/browse/JDK-6292965
https://lists.freebsd.org/pipermail/svn-src-head/2015-March/069337.html

Oops, the second link is actually about freebsd, not glibc... But the first one
is about glibc, from 12 years ago.

--- Comment #7 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
The floating-point state is logically like a thread-local variable.
Indeed, on some platforms some parts of it *are* TLS variables.
It would be wrong for siglongjmp to restore the value of a thread-local
variable to what it was when sigsetjmp was called - the user program might
have changed it after calling sigsetjmp, and that change must remain in
effect. Likewise, it would be wrong for siglongjmp to restore the
floating-point environment to what it was when sigsetjmp was called -
changes made by the user program must remain in effect. You want the
state as it was before the kernel called the signal handler, but
siglongjmp doesn't have access to that information.
Note that POSIX explicitly says about longjmp (and the siglongjmp
differences don't matter): "All accessible objects have values, and all
other components of the abstract machine have state (for example,
floating-point status flags and open files), as of the time longjmp() was
called, except that the values of objects of automatic storage duration
are unspecified if they meet all the following conditions".

The bug is here:
$ ld.gold -shared -z now -o libbar.so bar.o
You must link against the relevant glibc DSOs if you use symbols from glibc,
otherwise the resulting shared object is undefined.
If you don't do that, your DSO will not be future-proof, and you can run into
issues like bug 20489 after a glibc upgrade.

Sorry, that was a poor testcase. However, linking -lc at this point doesn't
make any difference. Linking -lpthread does, but the point is that libbar
doesn't use any symbols from libpthread itself and has no reason to link with
that library.

--- Comment #28 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Back to the issue reported on the bug report, I am still working on a fix for
this issue and I am currently rebasing my changes against master and checking
if there is any missing issue that I need to take care of.
I have decided to extend this fix in basically two subtasks that complement
each other:
1. Consolidate all the cancellation syscall implementations on C code to
remove the requirement of syscall-cancel.h header. This is orthogonal
to cancellation fix and aims to make the architecture adjustment simpler
(less assembly-macro code that emulates functions calls).
2. The cancellation (bz12683) fix itself which will require multiple patches
for each architecture.
For 1. I have a set of 33 patches, which 2 I already sent for review without
reply [1] [2]. The rest is similar to consolidation patches I have been
working to set a C implementation plus architecture defines to set the correct
syscall usage.
For 2. the patch is incomplete regarding architecture support. Based on current
implementation, I have added fixes for only x86, powerpc, s390, aarch64, and
arm. I summarize the steps required for each architecture fix at [3] and I
plan to review it after the patch rebase I am working it.
However for correct fix I am foreseeing some issues that I will need to take
care when more architectures are fixed:
1. i386 syscall code when using cancellation is suboptimal using this
cancellation mechanism due the not usage of vDSO. This has been
discussed on LKML on how kernel could help userland to accomplish
it, but afaik discussion was stalled.
2. Current code assumes maximum of 6 arguments syscalls for the
helper bridge. This is true for most architecture, however afaik
MIPS has 7 argument cancellable syscall, which will require code
adjustment. To avoid more performance issues, ideally both the
bridge function and related declaration should be arch-specific
(6 arguments if not specific, otherwise 7).
I am currently tracking some issues that have arise from code rebase and I will
check on the architectures I have access (x86, powerpc64le, arm, aarch64). For
1. I also plan to have a full make/check using all the supported architectures
and as soon I have all fixed I plan to update my sourceware branch [5] and
re-start discussion for 2.26.
My plan is at least to have 1. on 2.26. I will update the bugzilla with this
report.

Fixed for glibc 2.24 by
commit c867597bff2562180a18da4b8dba89d24e8b65c4
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Wed Jun 8 13:57:50 2016 -0700
X86-64: Remove previous default/SSE2/AVX2 memcpy/memmove
Since the new SSE2/AVX2 memcpy/memmove are faster than the previous ones,
we can remove the previous SSE2/AVX2 memcpy/memmove and replace them with
the new ones.
No change in IFUNC selection if SSE2 and AVX2 memcpy/memmove weren't used
before. If SSE2 or AVX2 memcpy/memmove were used, the new SSE2 or AVX2
memcpy/memmove optimized with Enhanced REP MOVSB will be used for
processors with ERMS. The new AVX512 memcpy/memmove will be used for
processors with AVX512 which prefer vzeroupper.
Since the new SSE2 memcpy/memmove are faster than the previous default
memcpy/memmove used in libc.a and ld.so, we also remove the previous
default memcpy/memmove and make them the default memcpy/memmove, except
that non-temporal store isn't used in ld.so.
Together, it reduces the size of libc.so by about 6 KB and the size of
ld.so by about 2 KB.

This is actually a very nice test case, thanks.
The “fix†for bug 20019 is clearly bogus and needs to be reverted.

We want to relocate libc.so before perform relocation against IFUNC
function defined in libc.so from other shared objects. We can either
revert the fix for PR 20019 or restrict the check to libc.so.

commit ec2a88b3c659ad4f5a662ca289edae4f0dc19d88
Author: Roland McGrath <roland@hack.frob.com>
Date: Fri Feb 6 10:53:27 2015 -0800
Clean up NPTL longjmp to be compat-only.
I got
(gdb) r
Starting program: /export/home/hjl/bugs/libc/pr21041/main-dynamic
warning: Unable to find libthread_db matching inferior's thread library, thread
debugging will not be available.
Program received signal SIGSEGV, Segmentation fault.

#3 0x00000000004005f9 in main ()
(gdb)
The problem is
(gdb) disass longjmp_resolve

__libc_longjmp@GLIBC_PRIVATE + 0
This is the same problem which my fix for PR 20019 tries to detect.

Bug ID: 21046
Summary: bug16159 seem to have happened again
Product: glibc
Version: 2.17
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: chenwei68 at huawei dot com
Target Milestone: ---
Created attachment 9751
--> https://sourceware.org/bugzilla/attachment.cgi?id=9751&action=edit
more gdb info in attchment
But recently, I met the deadlock problem again.
centOS 7.2 with glibc-2.17, which has already back ported the patch
fff94fa(Avoid deadlock in malloc on backtrace (BZ #16159))
The main problem is the process does not abort, it hangs. M_CHECK_ACTION
parameter is default value 3.
Backtrace from gdb is similar with BZ #16159, but different expection reason
detected.
The 1st expection triggered by calling free func. The pointer to free is an
address of array(calloc), and out-of-bounds access before.
So the 1st expection is "free(): invalid next size (normal)" and in
malloc_printerr func malloc report the 2nd error
"malloc(): smallbin double linked list corrupted", then it hangs around in:
pthread_once
__GI___backtrace

Bug ID: 21047
Summary: arm: fpu_control.h: _FPU_GETCW/_FPU_SETCW is rejected
by clang
Product: glibc
Version: unspecified
URL: https://llvm.org/bugs/show_bug.cgi?id=23998
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: vapier at gentoo dot org
Target Milestone: ---
we hit a bug building an audio package under clang as it rejected the inline
asm. when reported to the clang guys, they said the asm as written was
incorrect. see this bug report:
https://llvm.org/bugs/show_bug.cgi?id=23998
their suggestion was to write the macros:
"vmrs %0, fpscr"
"vmsr fpscr, %0"
i'm not familiar enough with ARM assembly to judge this myself.

I just did a superficial test with glibc 2.24 and I think you may be right that
it is broken there too. In a real application the failure is less obvious
prior to your patch because it only crashes when longjmp() is actually called
(which may happen rarely or never) whereas with your patch installed the binary
won't even start. But it looks as though it may not have worked correctly for
some time.

--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
See what I said on #glibc on 2016-02-22. In short: the present form is
deliberate and required for use within glibc built for soft-float where
use of these macros is runtime-conditional. It would be OK to use
explicitly VFP forms in the !__SOFTFP__ case (both inside and outside
glibc; outside glibc this code isn't used for __SOFTFP__ anyway).
[2016-02-22 23:11:49] <norris> I'm seeing some clang issues on ARM/glibc,
due to a glibc FPU macro
[2016-02-22 23:12:03] <norris> llvm folks seem to suggest it's glibc's
problem: https://llvm.org/bugs/show_bug.cgi?id=23998
[2016-02-22 23:12:25] <norris> should I file a glibc bug?
[2016-02-22 23:15:27] <jsm28> norris: glibc deliberately uses the mrc/mcr
forms of coprocessor instructions in various cases.
[2016-02-22 23:15:50] <jsm28> norris: For example, these macros need to
work in runtime conditional code in glibc that is compiled without VFP
enabled in the compiler.
[2016-02-22 23:16:08] <jsm28> norris: So use of vmrs/vmsr would not be
appropriate.
[2016-02-22 23:17:04] <jsm28> norris: Though when not compiling glibc,
these macro definitions are conditional on VFP being enabled, so you
should never see them with VFP disabled.
[2016-02-22 23:18:02] <jsm28> norris: So if you want to file a glibc bug,
you'll need a better justification of why these instructions are actually
invalid in this context (VFP enabled), not the assertions about another
way to write them.
[2016-02-22 23:49:06] <norris> jsm28: hmm, well the LLVM devs seem to
think these instructions aren't required on ARV v7a, even with VFP. I'm
not much of an expert to convince otherwise
[2016-02-22 23:49:14] <norris> jsm28: thanks though!
[2016-02-22 23:49:26] <jsm28> norris: I don't consider this a meaningful
thing to think.
[2016-02-22 23:49:59] <jsm28> norris: They are, or are meant to be, simply
the generic way of writing certain VFP instructions. I.e., they must be
supported exactly when those VFP instructions are supported.
[2016-02-22 23:50:49] <jsm28> norris: If they didn't correctly correspond
to the encodings of those VFP instructions, the problem would be much more
obvious. So I must assume they are correctly encoded.
[2016-02-22 23:52:03] <jsm28> norris: As far as I'm concerned, it's
fundamentally ill-conceived for an assembler to try to reject these ways
of writing these instructions, as the LLVM assembler apparently is doing.

--- Comment #12 from Matej Krizan <krizan at eset dot sk> ---
Hello,
let me resurrect this bugreport and stress the grave severity of it by another
example:
#include <string.h>
#include <stdio.h>
#include <locale.h>
int main()
{
setlocale(LC_ALL, "en_US.UTF-8");
const char s1[] = "\343\202\244", s2[] = "\343\203\211";
printf("%s\n%s\nstrcoll: %i\nstrcmp: %i\n",
s1, s2, strcoll(s1, s2), strcmp(s1, s2));
return 0;
}
which outputs (using glibc 2.24 on Fedora25):
イ
ド
strcoll: 0
strcmp: -1
meaning that *strcoll is unusable in any sane program*, because it can say that
different characters are equal in the (probably) most common en_US.UTF-8
locale.

--- Comment #3 from Paul Eggert <eggert at gnu dot org> ---
The FreeBSD memcchr is a kernel function, not a C library function, so it's not
really a precedent.
I've seen similar functions in application code (e.g., all_zeros in
grep/src/grep.c, zero_block_p in src/tar/sparse.c). The functions are easy to
write, not likely to be wrong, and not a performance bottleneck since they are
typically applied to input data and the cost of input dwarfs the cost of
running the function. Since these functions would need to be retained in the
source code anyway (which needs to be portable to non-glibc systems) from an
application viewpoint there doesn't seem to be much advantage to adding this
functionality to the glibc API.

The kernel version of RHEL 7.1 LE is 3.10.0. Hence using that to set
arch_minimum_kernel for powerpc74le. SLES12 and Ubuntu 14.04 has greater
version than 3.10.0 for powerpc.

Clear list of acquired robust mutexes in the child process after forking.
Robust mutexes acquired at the time of a call to fork() do not remain
acquired by the forked child process. We have to clear the list of
acquired robust mutexes before registering this list with the kernel;
otherwise, if some of the robust mutexes are process-shared, the parent
process can alter the child's robust mutex list, which can lead to
deadlocks or even modification of memory that may not be occupied by a
mutex anymore.

robust mutexes: Fix broken x86 assembly by removing it
lll_robust_unlock on i386 and x86_64 first sets the futex word to
FUTEX_WAITERS|0 before calling __lll_unlock_wake, which will set the
futex word to 0. If the thread is killed between these steps, then the
futex word will be FUTEX_WAITERS|0, and the kernel (at least current
upstream) will not set it to FUTEX_OWNER_DIED|FUTEX_WAITERS because 0 is
not equal to the TID of the crashed thread.
The lll_robust_lock assembly code on i386 and x86_64 is not prepared to
deal with this case because the fastpath tries to only CAS 0 to TID and
not FUTEX_WAITERS|0 to TID; the slowpath simply waits until it can CAS 0
to TID or the futex_word has the FUTEX_OWNER_DIED bit set.
This issue is fixed by removing the custom x86 assembly code and using
the generic C code instead. However, instead of adding more duplicate
code to the custom x86 lowlevellock.h, the code of the lll_robust*
functions
is inlined into the single call sites that exist for each of these
functions
in the pthread_mutex_* functions. The robust mutex paths in the latter
have been slightly reorganized to make them simpler.
This patch is meant to be easy to backport, so C11-style atomics are not
used.

--- Comment #2 from Rajalakshmi <raji at linux dot vnet.ibm.com> ---
Linux 3.13 was the first upstream version to support powerpc64le, but 3.10 is
the oldest kernel version known to still be supported on powerpc64le.

My fix for PR 20019 prevents broken applications from start. It is unsafe
for IFUNC resolver to reference external symbols as shown here.

--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
I interpret such statements in terms of semantics of certain encodings
being defined elsewhere, not in terms of what source code the assembler
should accept (where there is a clear use for being able to assemble the
instructions in runtime-conditional code when VFP is otherwise disabled
and without marking the objects as depending on VFP). There is of course
the possibility of using .inst directives but then you have to deal with
ARM/Thumb encoding differences which would run into problems with
attributes being used to control whether a particular function is ARM or
Thumb, and I'm not sure it would be possible to substitute an operand
register number appropriately in such a directive.
That is, the ability to access arbitrary coprocessor numbers via the
generic names, corresponding to where the ARMv7 ARM (and v8 before version
j) says 'if coproc IN "101x" then SEE "Advanced SIMD and Floating-point";'
(and where it permits other coprocessor numbers also not allowed for v8,
as used in the setjmp / longjmp iWMMXt support) is part of the GNU
assembler syntax required for building glibc. This functionality is
however not needed in any essential way for hard-float builds or use of
the installed header so it would be reasonable for the installed header to
use the explicit VFP syntax in the hard-float case if someone wishes to
implement that, for greater compatibility with different assemblers.

Patch to ./sysdeps/hppa/__longjmp.c
While compiling the gforth debian package on hppa I noticed that it crashed
while running the testsuite.
Debugging showed that the crash happened in ____longjmp_chk().

0xf98b5a90 <+176>: ldw 30(r26),r14
The code of __longjmp is this:
void __longjmp (__jmp_buf env, int val)
{
/* We must use one of the non-callee saves registersfor env. */
register unsigned long r26 asm ("r26") = (unsigned long)&env[0];
register unsigned long r25 asm ("r25") = (unsigned long)(val == 0 ? 1 : val);
#ifdef CHECK_SP
CHECK_SP (env[0].__jmp_buf.__sp);
#endif
....
inline-asm(...., r25 r26)
}
__longjmp uses a register variable (%r26) to hand over &env[0] to the inline
assembly later down.
On the other hand, if the new stack pointer is higher than the current stack
pointer, CHECK_SP() calls INTERNAL_SYSCALL() which clobbers %r26.
Attached patch avoids this problem by moving the assignment of r25 and r26 down
below the CHECK_SP() macros and putting it in a seperate {...} block. That way
the compiler will correctly take care of saving the needed variables (r25/r26)
across the INTERNAL_SYSCALL() call.
Build- & Run-tested on hppa-linux with the gforth debian package.

--- Comment #4 from Andreas Schwab <schwab@linux-m68k.org> ---
Compare MLA in T1 encoding vs MUL in T2 encoding. MLA does not allow r15, and
the assembler rejects it. MUL isn't just an alias for a particular MLA
encoding, but a different insn. Same for MCR/MRC vs VMSR/VMRS.

--- Comment #5 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
There is a clear case for the assembler to accept these coprocessor names
for these instructions, or otherwise provide syntax that inline asm can
use to access them, with register etc. operands substituted in, without
requiring VFP support at assembly time and without marking objects as
using VFP. It just so happens that the clang assembler is missing this
feature (which you can consider a feature of the GNU assembler language
for ARM that's outside the ARM-defined language, if you wish) required for
building glibc for ARM. I don't know if it has an alternative syntax for
that purpose of building code with runtime-conditional uses of VFP, but
for using the installed header adding an alternative using the VFP names
for !__SOFTFP__ would suffice if someone wishes to implement that.

sure, I can do that.
One question before that:
I did built the debian glibc package with my change.
But it failed to build because there were 2-3 bugs while running the testsuite.
One failure was tst-cancel2 (or something like that), the other one was
some NIS testcase (although I can understand that, because I was building
on a machine at SAP where NIS is active and as such it doesn't behaved like
a standard debian buildd).
What makes me wonder is, that glibc package is uploaded in debian, but
in my build I saw the failure (I'm sure the failures are not due to that
change).
Did you uploaded the debian glibc packages manually?

I have never done a build with NIS. tst-cancel2 doesn't normally fail.

I can't quite remember but I think that I added
malloc/tst-malloc-thread-fail to the xfail list
as it shows as an XPASS in the last build. We also had a random segv
building intl/tst-gettext6
in one of the attempts. I've not seen that before.
I've reached the conclusion that non of my kernel patches are helping
with the random segmentation
faults. Something else is causing them and possibly using the tmpfs for
unpacking, etc, has mad things
worse.
I do build trunk outside the buildd. Have a patch to fix pthread_cond_t
issue and others. Trunk built okay
a week or so ago. However build last night failed due to a missing
symbol link error (think symbol
was _init).

Running perf top to look at what's going on in my app shows 7% of CPU in
_tz_convert and 5% in spin lock, with no locks being done in my code. This
means that we are spending almost as much time in spin lock (without ever
waiting on it) as we are in the rest of _tz_convert.
The code in question is has 3 identical threads: tight loop iterating (c++11
for (auto &it: mymap)) a std::multimap with a significant number of lines of
code, only a few of which call into libc (or any other library). What goes
into the libraries are array accessors and iterator accessors to the
std::multimap (which has no locks) and the following code block:
struct tm t;
localtime_r(&nowTime.tv_sec, &t).
Nowtime is a struct timeval (previously filled by gettimeofday() calls by
another program run days before).
This is called once per record (my test case has We also call once per record,
there are 157,669,045 records (for my small test sample)).
For every record, we also call fwrite_unlocked(), which according to the manual
page doesn't have a lock (and by the name).
In looking inside localtime_r via
http://code.metager.de/source/xref/gnu/glibc/time/localtime.c, the code is as
follows:
struct tm *
localtime (const time_t *t)
{
return __tz_convert (t, 1, &_tmbuf);
}

http://osxr.org:8080/glibc/source/time/tzset.c?v=glibc-2.18), we have the
following block of code:
__libc_lock_lock (tzset_lock);
/* Update internal database according to current TZ setting.
POSIX.1 8.3.7.2 says that localtime_r is not required to set tzname.
This is a good idea since this allows at least a bit more parallelism.
*/
tzset_internal (tp == &_tmbuf && use_localtime, 1);
followed by much more code that access tp and calls various other _tz_
routines.
The correct solution should only be to lock if tp == &tmbuf (or the equivalent
for gmtime vs gmtime_r).
The lock prevents the parallelism mentioned in the comment.
To test this, create a routine that iterates for a long time calling
localtime_r for a given time_t value (it doesn't matter what the value is, as
long as it's valid). Then view with "perf top -p <pid>" of the program. Run
this with permissions so you can see into the kernel. Do this in multiple
threads.
A routine that uses a user-provided buffer and has no shared resources should
never need a lock. If "spin lock" shows up, the bug exists. If it doesn't
show up, the bug was fixed.
Looking with 2.24, we still have a similar problem. We aren't doing any
timezone manipulation, so presumably __use_tzfile is 0. The new critical code
block is:
__libc_lock_lock (tzset_lock);
/* Update internal database according to current TZ setting.
POSIX.1 8.3.7.2 says that localtime_r is not required to set tzname.
This is a good idea since this allows at least a bit more parallelism. */
tzset_internal (tp == &_tmbuf && use_localtime, 1);
if (__use_tzfile)
__tzfile_compute (*timer, use_localtime, &leap_correction,
&leap_extra_secs, tp);
else
{
if (! __offtime (timer, 0, tp))
tp = NULL;
else
__tz_compute (*timer, tp, use_localtime);
leap_correction = 0L;
leap_extra_secs = 0;
}
__libc_lock_unlock (tzset_lock);
So, tzset_internal shouldn't need to be locked according to the comment.
__offtime() should be safe, the only external variables/routines accessed are
__set_errno() on error (not in my case), and __mon_yday[__isleap(y], all of
which should be safe. __tz_compute() if called, might need a lock, but only
when accessing tz_rules (not sure if it does or doesn't). Unless there was an
error inside __offtime(), __tz_compute shouldn't be called anyway, so it would
be better to refactor the code to not lock at all for the majority case. It's
probably better to only lock for __tz_compute, and possibly inside
tzset_internal if the parameters indicate as much. That way, the majority of
the callers of localtime_r, gmtime, and gmtime_r are uneffected.
With the 2.12 version of libc we use, almost 50% of the time inside of
__tz_convert is a result of the spin lock (5% vs 7% for the rest of
__tz_convert.
Also note that my problem (the 5% vs. 7%) apply to a single thread, so the spin
lock overhead is if it never needs to wait for the lock. Multi-threaded apps
that have contention will be way worse (3 threads is 11% spin lock, 7%
_tz_convert for some of it, and then to the 5%/7%). We also spend 4% in
__offtime.
For a single threaded version, I have the following profile (44% in my code --
which does a lot; 8% in __strcmp_sse2 -- from tzset_internal , 5% in some stl
stuff; 4% in __offtime, 2.5% in __tz_convert, 2% in __mempcpy (probably related
to the timezone parser); 2% in __tzfile_compute, 1% in __tzstring, and a bunch
of lesser stuff (some related to localtime and it's children). So, at a
minimum from these numbers, 24.5% of my cycles are being consumed in a single
function, the rest of my code does a significant amount of string formatting
and I/O, the equivalent of an snprintf with about 15 numerical fields (int and
double) and a date/time output. Given the number of samples that will be
processed in production (10s of billions, not 150 million), a 10% improvement
of localtime_r is important (there aren't a whole lot of wasted cycles left for
the rest of it). The multi-threaded version will also be processing 10s of
billions of records, which is why the lock being removed is critical.

Bug ID: 21050
Summary: Prevent tailcall optimizations
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: tetra2005 at gmail dot com
Target Milestone: ---
Some libdl functions rely on return address to figure out the calling DSO and
then use this information in computation (e.g. output of dlsym depends on which
library called it).
As reported in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66826 this may
break under tailcall optimization i.e. in cases like
return dlsym(...);
Rich Felker suggested that adding new GCC attribute is a possible solution.
Another option would be to hack around dlsym to prevent tailcall from happening
e.g.
#define dlsym(h, name) { volatile void *sym = dlsym(h, name); return (void
*)sym; }
Which solution is more appropriate for Glibc?

--- Comment #3 from Alan Modra <amodra at gmail dot com> ---
Way back when we first ported powerpc64le I had a patch that set the kernel
version to 3.13, my reasoning being that 3.13 was the first official version
and RedHat surely could cope with patching their glibc to accept a 3.10 kernel.
At the time, I didn't analyse how glibc is affected by choosing 3.10 rather
than 3.13. The answer is, I think, not at all.

The <other arch> tests don't matter. dl-osinfo.h is setting up a runtime test
that the running kernel is at least the minimum glibc was compiled to support.
So we're left with just the standard linux/kernel-features.h tests, none of
which test a value between 3.10 and 3.13.
Just go with 3.10.

configure command and config.log output.
Hello,
When trying to compile glibc for arm using the attached configure command, it
fails to compile because it try to pass the flag '--32' to the cross assembler
which is not applicable to the cross assembler.
Regards,
Ataro.

You are missing a cross C++ compiler. Since it is only needed for the
testsuite this isn't a fatal error.

Sorry but I think that I do have a C++ compiler.
it is available in the gcc prefix directory: /root/andro_test/gcc-build/gcc/cpp

/<<PKGBUILDDIR>>/js/src/jit/BaselineCacheIR.cpp:827: confused by earlier

Preprocessed source stored into /tmp/ccuktZXb.out file, please attach this to
your bugreport.
As it turns out, Firefox has variables called R0/R1 in the global namespace
which conflict with the definitions that exist on Linux/SH in sys/ucontext.h in
glibc.
After some research, we found out that this issue has existed in the past
before on arm*-*-* and it was addressed with a patch by Peter Green (CC'ed) to
rename the register definitions in sys/ucontext.h [1].
Would it be possible to make the same changes to sys/ucontext.h as well without
breaking anything? From reading the discussion in [1], it seems the only
possible breakage could happen in gdb. However, since gdb isn't officially
supporting SH at the moment anyway, we don't have to worry about this part.
There might be a few other packages could potentially break, but I would be
willing to fix all of them and send patches upstream although I don't expect
that there are many users like JIT implementations for sh4, for example. I know
that Apple's JavaScriptCore has sh4 support, but it was recently dropped
because it was unmaintained [2].
Thanks,
Adrian

Did you add this to the PATH?
Your config.log shows it's not found:
configure:2920: checking for arm-linux-gnueabi-g++
configure:2950: result: no
And the configure falls back to trying the system G++:
configure:2964: checking for g++
configure:2980: found /usr/bin/g++
configure:2991: result: g++
And the system g++ won't work because you're building cross.

I think I've added it to the $PATH but somehow the configure script failed to
detect it. I also saw that it failed to find the nm cross compiled tool from
binutils and I've to add it manually to the config.make file.
However, I've started a clean build of binutils, gcc and glibc all with the
same --prefix directory and everything went all. (everything except that I was
must to add the -O2 and the -I/root/androd_test/linux-3.4.57 flags to the
$CFLAGS and $CPPFLAGS environment variables).
Thanks you for your replies.
Regards,
Ataro.

commit b040e1b0842c35ab444e8502db6ae59389d1e3d5
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jan 16 21:34:48 2017 +0000
Make soft-float powerpc swapcontext restore the signal mask (bug 21045).
The soft-float powerpc version of swapcontext does not restore the
signal mask, resulting in stdlib/tst-setcontext2 failing:
after getcontext
after setcontext
after swapcontext
FAIL: SIGUSR2 is blocked after swapcontext.
This patch fixes this by adjusting the arguments passed to
__sigprocmask so that it restores the saved signal mask as well as
saving the existing one. (For hard-float, this code is only used for
a compat symbol, not for the current version of swapcontext.)
Tested for soft-float powerpc.
[BZ #21045]
* sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S
(__CONTEXT_FUNC_NAME): Pass address of signal mask to be restored
to __sigprocmask.

Version|2.19 |2.25
--- Comment #1 from Carlos O'Donell <carlos at redhat dot com> ---
I can confirm this issue.
Fundamentally this code in pthread_detach is flawed:
36 /* Mark the thread as detached. */
37 if (atomic_compare_and_exchange_bool_acq (&pd->joinid, pd, NULL))
38 {
39 /* There are two possibilities here. First, the thread might
40 already be detached. In this case we return EINVAL.
41 Otherwise there might already be a waiter. The standard does
42 not mention what happens in this case. */
43 if (IS_DETACHED (pd))
44 result = EINVAL;
45 }
46 else
47 /* Check whether the thread terminated meanwhile. In this case we
48 will just free the TCB. */
49 if ((pd->cancelhandling & EXITING_BITMASK) != 0)
50 /* Note that the code in __free_tcb makes sure each thread
51 control block is freed only once. */
52 __free_tcb (pd);
Once ownership of PD is released on line 37 we may never be touched again.
There is a resource leak that we can't prevent in the current implementation.
e.g.
T1:
(a) Check if I'm detached.
(b) If detached then free resources.
(c) Exit.
Any thread T2 may make T1 detached after (a) and create a scenario where T2
doesn't know if T1 was detached before (a) or after (a) and can't check without
risk of segfault if PD is unmapped.
The detach sequence needs to be rewritten such that (a) is done atomically and
is not just a check but writes information back into PD to indicate to T2 that
it has already shut down far enough that it will not be freeing it's own
resources. In that case T2 can, in pthread_detach, carry out the free of the
resources, knowing PD is still around.
The only immediate workaround I can suggest is to start the thread detached
rather than trying to set the detached status at a later point in time.
I do not expect this to get fixed in 2.25 (Feb 1st 2017).

commit 570c443352023691f4f7c9ed40199f18c746568c
Author: Stefan Liebler <stli@linux.vnet.ibm.com>

S390: Fix FAIL in test string/tst-xbzero-opt [BZ #21006]
On s390x this test failed with:
FAIL: explicit clear/test: expected 0 got 1
In setup_explicit_clear, the buffer is filled with the test_pattern.
On s390x the memcpy in prepare_test_buffer is done by loading
r4 / r5 with the test_pattern and using store multiple instruction
to store r4 / r5 to buf.
If explicit_bzero is resolved in setup_explicit_clear, r4 / r5 is
stored to stack by _dl_runtime_resolve and the call to memmem in
count_test_patterns finds a hit of the test_pattern on the stack.
This patch resolves all symbols at program startup by linking with
-z now. This omits the call of _dl_runtime_resolve within
setup_explicit_clear and the test passes.
ChangeLog:
[BZ #21006]
* string/Makefile (LDFLAGS-tst-xbzero-opt): New variable.

As discussed, the longjmp semantics require preserving the floating-point
environment when longjmp is called, *not* restoring the environment from when
setjmp was called.

--- Comment #4 from Paul Eggert <eggert at gnu dot org> ---
This bug causes GNU coreutils Bug#22793 "grep -E assertion failure with back
references"; see <https://bugs.gnu.org/22793>. I'm adding comments to both bug
reports so that the connection between the two bugs is clearer.
Although this bug's current assignee is Paolo Bonzini (the original reporter),
I think Paolo is pretty busy doing other stuff. Is someone else available to
work on regex bugs? I suspect the fix for this bug will not be trivial.

C code to reproduce the bug
I attached a slightly-simpler C-language reproducer for the bug, derived from
the attachment in Bug#17356. If I compile and run this program, it outputs
"a.out: regexec.c:1375: pop_fail_stack: Assertion `num >= 0' failed." and then
aborts.

patch to fix the bug
Hi all,
I found there is a bug in time/tzset.c when porting some local patches to
the latest glibc release. In tzset_internal, there are such a branch:
/* Check whether the value changed since the last run. */
if (old_tz != NULL && tz != NULL && strcmp (tz, old_tz) == 0)
/* No change, simply return. */
return;
If users modified the local timezone file (usually /etc/localtime) while keep
the TZ environment variable untouched, the code fragment listed above will make
tzset_internal return , which is obviously not right. If /etc/localtime were
modified , tzname should be recalculated as the rules has changed.
IMO, "tz==old_tz" should only skip the blocks that save tz into old_tz. I
have made a patch for this problem ,see the attachment(I deleted two redundant
assignments for tz_rules.name at the same time).

--- Comment #3 from Diego Barrios Romero <eldruin at gmail dot com> ---
Created attachment 9761
--> https://sourceware.org/bugzilla/attachment.cgi?id=9761&action=edit
Symbol overwrite example
I found a different manifestation of this unpredictability w.r.t. the base
version of symbols.
I have attached an example program setup in which symbols are overwritten by
the base version even though a library specifies that it needs a specific
version.
The example contains two libraries (A and B) that offer the symbol f.
A does not define any version, but B does define it in version B_1.0.
Then there are two libraries (AU and BU) that use these libraries, each using
only one of them, and they offer the fAU and fBU functions.
Then a program 'p' links both libraries AU and BU (See makefile for more
information).
At run time, the symbol f that is requested by BU with version B_1.0 gets
matched with the base version one provided by library A. Even though the symbol
with the adequate version is also available, the base version is returned.
Here are the relevant symbol entries when doing objdump -TC
libA.so:
0000000000000705 g DF .text 0000000000000012 Base f
libB.so:
0000000000000765 g DF .text 0000000000000012 B_1.0 f
libAU.so:

libBU.so:
0000000000000000 DF *UND* 0000000000000000 B_1.0 f
It also happens the other way around, the f base version requested by AU is
overwritten by f@@B_1.0 if changing the link order (-lBU -lAU).
While this latter behaviour is also unexpected, matching the base version to a
symbol containing a specific version sounds definitely unexpected to me.
If you compile and run the program 'p', you should see something like this:
AU::fAU()
A::fA()
A::f()
A::f()
BU::fBU()
B::fB()
A::f()
A::f()
If you add version information to library A (uncomment commented line in the
makefile), you will see that the symbols get matched as expected and the
program reports:
AU::fAU()
A::fA()
A::f()
A::f()
BU::fBU()
B::fB()
B::f()
B::f()
I was able to reproduce this on ubuntu 14.04 (eglibc 2.19) and on ubuntu 16.04
(glibc 2.23).
I also had a look at the source code and think that the check_match subroutine
in elf/dl-lookup.c behaves unexpectedly.
To my outsider eyes, it sounded like the 'else' case below could be at fault.
It looks like it would return the default version if the version information
does not match but a non-hidden default version exists. This would of course
not be the case depending on "who-is-who" in these variables, but I could not
get any further.
const ElfW(Half) *verstab = map->l_versyms;
if (version != NULL)
{
if (__builtin_expect (verstab == NULL, 0))
{
/*...*/
}
else
{
/* We can match the version information or use the
default one if it is not hidden. */
ElfW(Half) ndx = verstab[symidx] & 0x7fff;
if ((map->l_versions[ndx].hash != version->hash
|| strcmp (map->l_versions[ndx].name, version->name))
&& (version->hidden || map->l_versions[ndx].hash
|| (verstab[symidx] & 0x8000)))
/* It's not the version we want. */
return NULL;
}
/*...*/
I tried adding a version_matched flag and keep looking in other 'scopes' (see
for loop in function _dl_lookup_symbol_x) for a better match instead of
returning the first one but it did not immediately work so I decided to report
it here instead.
Does this example help you reproduce this?

A script to check versions of IFUNC symbols in libpthread.so and libc.so
We can remove the IFUNC symbols in libpthread.so if those
symbols in libc.so have the same versions in libc.so and
another symbol in libpthread.so has the same version so that
removing the IFUNC symbols in libpthread.so won't change
version dependencies for libc.so and libpthread.so. Here
is the script to check them.

Do you really mean “base version†here? Isn't this an unversioned symbol?
Ulrich Drepper's description of symbol versioning is pretty clear that
unversioned symbols preempt all versioned symbols of the same name, no matter
what the symbol version is. I believe the original intent for this design
choice was that it allows to introduce symbol versioning in a future library
version, while still permitting existing binaries to interpose those symbols.
No matter what the original choice was, we today have many interposing
libraries (such as alternative malloc implementations) which depend on this
particular behavior of the dynamic linker.
I agree this behavior is surprising, but the behavior described in comment 3
does not qualify as a bug.
Let's keep this bug open for the original issue (dlsym result depends on hash
chain ordering in a surprising way).

commit 3a66b2b0637e439fb0e7a14c6c3d4c58190eec61
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu Jan 19 00:05:34 2017 +0000
Fix ARM fpu_control.h for assemblers requiring VFP insn names (bug 21047).
Bug 21047 reports that the clang assembler disallows the ARM
implementations of _FPU_GETCW and _FPU_SETCW.
These are deliberately written the way they are, using generic
coprocessor instructions (from the days when VFP was just one possible
coprocessor for ARM) that have the right encodings, to handle the case
of the instructions being used runtime-conditionally inside glibc,
where use of these macros is not meant to result in either the
assembler requiring VFP to be enabled at assembly time or in it
marking the object as using VFP. However, more recent ARM ARM
versions have restricted the definitions of the coprocessor
instructions and reportedly the clang assembler follows that in
disallowing those names for VFP instructions.
In the non-__SOFTFP__ case - which in fact is the only case where
these macro definitions can be used outside the build of glibc itself
- using VFP instruction names is of course fine, since we know that
VFP is enabled for that compilation. Thus, this patch uses the
current VFP names for these instructions in that case to improve
compatibility for this header file.
Tested for hard-float and soft-float builds of glibc, including that
installed stripped shared libraries are unchanged by the patch.
[BZ #21047]
* sysdeps/arm/fpu_control.h [!__SOFTFP__] (_FPU_GETCW): Use VFP
name for instruction.
[!__SOFTFP__] (_FPU_SETCW): Likewise.

After rebuilding glibc with the patch applied, I can build Firefox on sh4.
Can we get this applied?

commit fe3f0488daaec2fb8c3af181b6e8e4567ba2cf61
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu Jan 19 20:57:16 2017 +0000
Restore clock_* librt exports for MicroBlaze (bug 21061).
MicroBlaze had clock_* functions exported from librt in glibc 2.18 and
2.19, as confirmed in
<https://sourceware.org/ml/libc-alpha/2017-01/msg00369.html>, and they
then disappeared in 2.20, presumably as a result of the fix
<https://sourceware.org/ml/libc-alpha/2014-02/msg00598.html> for a
Versions.def bug that had resulted in their unintended inclusion in
2.18 (followed by removal of the Versions.def mechanism that allowed
such bugs).
As they were released in that library, they should be considered part
of the GLIBC_2.18 ABI and so restored for the sake of any binaries
that expect them in that library. This patch restores them by adding
a MicroBlaze version of clock-compat.c that overrides SHLIB_COMPAT.
Tested (compilation only) with build-many-glibcs.py (where this fixes
the librt ABI test failure; elf/check-execstack still fails and still
needs architecture maintainer attention to fix it or XFAIL it with an
appropriate explanatory comment).

Summary: printf may deadlock when threads get cancled
Product: glibc
Version: 2.24

test case to reproduce the bug
Hi all,
I found a bug may cause deadlock still existed in the latest glibc source.
For a static binary, when a thread which is going through the printf function
get cancled, the stream lock will not be unlocked.
In ./sysdeps/nptl/libc-lockP.h, _pthread_cleanup_push_defer were declared to
be a weakref. So, in macro __libc_cleanup_region_start(in
sysdeps/nptl/libc-lock.h), after "_avail = PTFAVAIL
(_pthread_cleanup_push_defer);", _avail will turn out to be 0 as there are no
strong references for _pthread_cleanup_push_defer.
This bug can be reproduce by the attached file(I have tested it under
glibc-2.24 x86-64).

This bug is easy to fix, just two PTHREAD_STATIC_FN_REQUIRE in pthread_create.c
will be enough. See the attached patch.
By the way, guys using glibc from redhat(or other distributions) probably can
not reproduce the bug. Packaged maintainers re-linked all objects from
libpthread.a(using ld -r) into a single object file, and rebuild the
libpthread.a from that object. So , _pthread_cleanup_push_defer will always
exist in the final binary, and of course the bug will not be reproducible
then.

This bug is not only seen with extA characters, but also seen with simple
punctuations and/or kanas.
$ printf '%s\n' ， 。 ： ￥ ゠㋠ア カ a b c , . : $ | LC_COLLATE=zh_CN.UTF-8 sort -u

$

(uniq does the same thing.)
It seems that glibc is just eating away anything not on that list. (What kind
of equivalence assumption is that?)

Bug ID: 21073
Summary: tunables: insecure environment variables passed to
subprocesses with AT_SECURE
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Flags: security+
Without tunables, MALLOC_CHECK_ is stripped from the environment, so that it is
not accidentally passed to subprocesses. (The intent is that subprocesses do
not inadvertently pick up malicious environment settings.)
This does no longer happen if tunables are enabled. Similarly, the
GLIBC_TUNABLES variable is not rewritten to drop the equivalent option, either.
To reproduce this, I created a small test program and made it SUID root:
#include <stdlib.h>
#include <unistd.h>
int
main (void)
{
setuid (0);
system ("env");
}
Running it as an ordinary user should result in no output:
GLIBC_TUNABLES=glibc.malloc.check=0 LD_DEBUG=files MALLOC_CHECK_=0 ./a.out \
| egrep '^(LD|MALLOC|GLIBC)_'
But I get this output:
MALLOC_CHECK_=0
GLIBC_TUNABLES=glibc.malloc.check=0
(Without tunables support, the GLIBC_TUNABLES variable may still be printed.)

--- Comment #1 from Siddhesh Poyarekar <siddhesh at sourceware dot org> ---
The environment variable is not stripped, but it is not honoured either. That
is, glibc ignores the environment variable and its value. We cannot guarantee
what MALLOC_CHECK_ does for external allocators, can we?

I tried this before, but it does not work with the current dynamic linker:
https://sourceware.org/ml/libc-alpha/2016-05/msg00176.html
I never received a clarification if this behavior is required, or a dynamic
linker bug.

Ah, right, but for the ^C case, you can just hit ^C again. With the proposed
change, that possibility is gone.

powerpc: Fix write-after-destroy in lock elision [BZ #20822]
The update of *adapt_count after the release of the lock causes a race
condition when thread A unlocks, thread B continues and destroys the
mutex, and thread A writes to *adapt_count.
(cherry picked from commit e9a96ea1aca4ebaa7c86e8b83b766f118d689d0f)
(with changes from commit eb1321f291515dae75c83a40c39e775fdd38e97a)

powerpc: Fix write-after-destroy in lock elision [BZ #20822]
The update of *adapt_count after the release of the lock causes a race
condition when thread A unlocks, thread B continues and destroys the
mutex, and thread A writes to *adapt_count.
(cherry picked from commit e9a96ea1aca4ebaa7c86e8b83b766f118d689d0f)
(with changes from commit eb1321f291515dae75c83a40c39e775fdd38e97a)

Bug ID: 21075
Summary: unused assigment to %g4 in sparc/sparc64/clone.S
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: ivo.raisr at oracle dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Function __clone in sysdeps/unix/sysv/linux/sparc/sparc64/clone.S
contains an unused assignment to %g4:
mov %i2, %g4
Register %g4 is not used anywhere afterwards.
Previous assignments to %g2 and %g3 make sense, because 'fn' and 'arg'
arguments
need to be preserved across __NR_clone system call.
However there is no need to preserve 'flags' argument - it is used only for
__NR_clone system call (where it is passed in %o0).

I have a patch ready and the goal is to fix it for the upcoming release. I
should get the patch out by today. The issue is on the release blockers list
now.

--- Comment #4 from Carlos O'Donell <carlos at redhat dot com> ---
SIGCANCEL cannot be lost. The parent in __pthread_initialize_minimal_internal
will setup the handler long before any pthread_create code is run.
I think the simplest solution is actually to make the parent responsible for
the cleanup since it is the owner of the PD after create_thread returns an
error.
So the parent should run pthread_join on PD to reap the stack.
e.g.
682 if (__glibc_unlikely (retval != 0))
683 {
684 /* If thread creation "failed", that might mean that the thread got
685 created and ran a little--short of running user code--but then
686 create_thread cancelled it. In that case, the thread will do all
687 its own cleanup just like a normal thread exit after a successful
688 creation would do. */
689
690 if (thread_ran)
691 assert (pd->stopped_start);
If thread_ran, and !detached, then stopped_start == true, so the user code
can't have run and detached itself, so we are still the owner of PD and can
issue a pthread_join to reap the thread.

commit 3e1b518550634792de13332edaab0ad722322c2b
Author: James Clarke <jrtc27@jrtc27.com>
Date: Tue Jan 24 09:20:06 2017 -0200
Bug 21053: sh: Reduce namespace pollution from sys/ucontext.h
The problem is basically that sys/ucontext.h is defining R0..R15
which happens to conflict with some packages like Firefox when
trying to build on SH.
The very same problem existed on arm back then [1] and it was fixed by
renaming R0..R15 to REG_R0..REG_R15. This patch imploy a similar
strategy for SH.
Checked on sh4-linux-gnu with run-built-tests=no and I also got reports
that it fixes Firefox build on Debian sh4.
* sysdeps/unix/sysv/linux/sh/sh3/ucontext_i.sym: Use new REG_R*
constants instead of the old R* ones.
* sysdeps/unix/sysv/linux/sh/sh4/ucontext_i.sym: Likewise.
* sysdeps/unix/sysv/linux/sh/sys/ucontext.h (NGPREG): Rename...
(NGREG): ... to this, to fit in with other architectures.
(gpregset_t): Use new NGREG macro.
[__USE_GNU]: Remove condition; all architectures other than tile
are unconditional.
(R*): Rename to REG_R*.

Summary: Missing vzeroupper in memset-vec-unaligned-erms.S
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: string
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
Target: x86_64
Since memset-vec-unaligned-erms.S has VDUP_TO_VEC0_AND_SET_RETURN at
function entry, memset optimized for AVX2 and AVX512 will always use
ymm/zmm register. VZEROUPPER should be placed before ret in
L(stosb):
movq %rdx, %rcx
movzbl %sil, %eax
movq %rdi, %rdx
rep stosb
movq %rdx, %rax
ret
since it can be reached from
L(stosb_more_2x_vec):
cmpq $REP_STOSB_THRESHOLD, %rdx
ja L(stosb)

patch to fix the bug
Hi all,
I found the dynamic linker did not check the return value when allocating
tlsblocks(csu/libc-tls.c and elf/rtld.c). There are some explanations in
comments, but they failed to convince me. Users will only get a segment-fault
when there are no memory for tlsblocks. They will get confused as there are no
helping message printed. Moreover, there many similar checks for memory
allocations. So ,why not do the same for tlsblocks?
I have added a patch to fix the problem(see attachment), it that ok for
trunk?

patch to fix the bug
Hi all,
I found the bug in robust timed mutex still existed in the latest glibc
source, when porting some local patches to the newest glibc release.
Provided there were 3 threads A，B and C， all of which were trying to
manipulate the same robust mutex. See the following illustration.
A: B: C:
pthread_mutex_lock(m);
pthread_mutex_timedlock(m);
pthread_mutex_lock(m);
pthread_mutex_unlock(m);
pthread_mutex_lock(m);
pthread_mutex_unlock(m);
First, A locked m. Then B and C try to lock m, and both get traped(wait in
kernel).
A unlock m, wake up B and clear the FUTEX_WAITER flag.
After B wake up(and have not do anything yet), A preempt B and lock m again. At
this time， A will not add FUTEX_WAITER flag to m as it does not know whether
there are other waiters.
B continue to run, it call gettimeofday and find the time is out. So, it just
return ETIMEOUT without trying to set FUTEX_WAITER flag.
A unlock m , and do not do the wake syscall as there is no FUTEX_WAITER.
C get stuck in kernel forever.
The core logic of this problem is that pthread_mutex_timedlock should set the
FUTEX_WAITER flag before check timeout. So, the fix to the bug is very simple.
We just need to move the code block which set the FUTEX_WAITER flag forward. I
have created a patch to fix(see attachment) , is it ok for trunk?

tarball with core and libs
This came from a problem in some LTP test, which segfaulted. Trying to open
the corresponding core with any gdb version hangs in libthread_db in
iterate_thread_list. Now it's of course no wonder that if the list is corrupt
that iteration breaks, but perhaps libthread_db can be made a bit more robust
(e.g. counting the loop iterations against an expected number of threads,
or a tortoise-and-hare algorithm to protect against internal cycles).
The attachment contains the exe, the core and the necessary libs to make
gdb not error out with mismatching libs warnings. Of course for _that_
libthread_db the problem can't be fixed anymore but perhaps for the future.

For reference this is bug 1020166 at bugzilla.suse.com, but it's marked
internal so can't be accessed for most people.

Oh and, to see the problem, just untar the tarball and run ./rungdb.sh
from inside the bug subdir. It does:
% gdb -iex "set solib-absolute-prefix `pwd`" \
-iex "add-auto-load-safe-path `pwd`/lib64/libthread_db.so.1" \
pthread_create_14-1.run-test core
to make it find the packaged libs.

If the allocation fails, sbrk will crash because errno has not been set up at
this point. There is really no good way to deal with this situation.

I'm flagging this as security- because NIS data is trusted in most environments
although it comes from the network (trusted in the sense that tampered NIS data
could break the system security policy).

Do you have a test case for this?
Netlink is de-facto non-blocking, so we should use system calls which are not
cancellation points, without a cancellation handler.

Out of curiosity, is there a reason why you cannot use libaio instead of the
glibc aio interface? Thanks.

--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Are you confident that these stack allocations can only be triggered by
(trusted) data from the network, not by e.g. a lookup of a crafted long
user name (something it's plausible could be triggered across a trust
boundary)?

Bug ID: 21088
Summary: Build fails with --enable-static-nss
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: stilor at att dot net
CC: drepper.fsp at gmail dot com
Target Milestone: ---
A build failure was reported in Crosstool-NG when glibc is configured with
--enable-static-nss: https://github.com/crosstool-ng/crosstool-ng/issues/555
The problem is with is_nscd/nscd_init_cb - with static NSS, they are defined
but not used. The definitions in question are protected by '#ifdef USE_NSCD'
while all their uses are inside '#ifdef USE_NSCD' blocks which are themselves
nested inside a '#ifdef SHARED' or '#if !defined DO_STATIC_NSS || defined
SHARED' block.

I do not have a test case for this. I reported this bug based on the inspection
of the called functions.
There is a related Red Hat bug:

Two reasons:
1) It (lio_listio()) is POSIX, so it may run on several machines.
2) I didn't know that there are two implementations ;-)
BTW: In the meantime I reimpemented my own mechanism that used a pool of max n
requests that is refilled by the application as soon as there is some slot
available, and n threads are doing the IOs vie pread(). That is very close to
what I wanted.

Ah. I was asking because it is not likely that we will make further changes to
the thread-based aio implementation in glibc.
I'm not sure if Linux actually offers truly asynchronous buffered I/O. Some
thread is needed to drive the I/O. But glibc (or any other aio implementation)
cannot spawn a separate thread for each I/O operation in the list because that
could lead to I/O thrashing.
I'm sorry but I think we should close this bug as WONTFIX.

We currently cannot use INTERNAL_SYSCALL in generic code, so this is more
complicated than it looks.

I'd strongly suggest to place a note in the manual pages mentioning the
restriction (I/O is not actually scheduled in parallel).

Indeed, you are right, the majority of the cases comes from
application-supplied data, not network-supplied data, so it seems this would
indeed be a security fix.

I agree that this should be fixed to support being more robust. The code in
question is pretty naive about corruption and that can lead to debugger
problems.

Summary|ld-linux crashing with |Running libc.so.6 as an
|SIGSEGV when preloading |executable triggers IFUNC
|libesets_pac.so to libc.so |relocation ordering issues
--- Comment #4 from Florian Weimer <fweimer at redhat dot com> ---
Dependency sorting always puts the main executable first, under the assumption
that nothing can have a DT_NEEDED dependency on it.
When libc.so.6 is executed as an executable, it takes that position, rather
than its usual position in the dependency order.
Relocation of objects precedes in a depth-first order. This means that
libpthread.so.0 is relocated before the main executable (libc.so.6 in this
case).
Relocation processing for the __gettimeofday symbol reference in
libpthread.so.0 calls the IFUNC resolver for this symbol in libc.so.6.
However, libc.so.6 has not been relocated at this point, and the reference to
_rtld_global_ro (behind the GLRO macro) is undefined.
So in short, this is another IFUNC ordering issue. The good news is that this
particular one can only happen if libc.so.6 is the main executable. Otherwise,
libc.so.6 is relocated before libpthread.so.0.
Shorter reproducer:
LD_PRELOAD=/lib64/libpthread.so.0 /lib64/libc.so.6

The libesets_pac.so is preloaded and needs to have all of it's dependencies
initialized first. I think it's a dynamic loader bug that all the DT_NEEDED of
the preloaded DSO are not initialized first.
Though I agree this is a corner case, but one which we could fix with proper
dependency handling.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

localedata: bs_BA: fix yesexpr/noexpr [BZ #20974]
Both regexes end with a "*." which means the previous match can be
omitted, and then the . allows them to match any input at all.
This means tools like coreutils' `rm -i` will always delete things
when prompted because the yesexpr regex matches all inputs (even
the negative ones).

Fix cos computation for multiple precision fallback (bz #20357)
During the sincos consolidation I made two mistakes, one was a logical
error due to which cos(0x1.8475e5afd4481p+0) returned
sin(0x1.8475e5afd4481p+0) instead.
The second issue was an error in negating inputs for the correct
quadrants for sine. I could not find a suitable test case for this
despite running a program to search for such an input for a couple of
hours.
Following patch fixes both issues. Tested on x86_64. Thanks to Matt
Clay for identifying the issue.
[BZ #20357]
* sysdeps/ieee754/dbl-64/s_sin.c (sloww): Fix up condition
to call __mpsin/__mpcos and to negate values.
* math/auto-libm-test-in: Add test.
* math/auto-libm-test-out: Regenerate.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

localedata: bs_BA: fix yesexpr/noexpr [BZ #20974]
Both regexes end with a "*." which means the previous match can be
omitted, and then the . allows them to match any input at all.
This means tools like coreutils' `rm -i` will always delete things
when prompted because the yesexpr regex matches all inputs (even
the negative ones).

Fix cos computation for multiple precision fallback (bz #20357)
During the sincos consolidation I made two mistakes, one was a logical
error due to which cos(0x1.8475e5afd4481p+0) returned
sin(0x1.8475e5afd4481p+0) instead.
The second issue was an error in negating inputs for the correct
quadrants for sine. I could not find a suitable test case for this
despite running a program to search for such an input for a couple of
hours.
Following patch fixes both issues. Tested on x86_64. Thanks to Matt
Clay for identifying the issue.
[BZ #20357]
* sysdeps/ieee754/dbl-64/s_sin.c (sloww): Fix up condition
to call __mpsin/__mpcos and to negate values.
* math/auto-libm-test-in: Add test.
* math/auto-libm-test-out: Regenerate.

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

localedata: bs_BA: fix yesexpr/noexpr [BZ #20974]
Both regexes end with a "*." which means the previous match can be
omitted, and then the . allows them to match any input at all.
This means tools like coreutils' `rm -i` will always delete things
when prompted because the yesexpr regex matches all inputs (even
the negative ones).

Fix cos computation for multiple precision fallback (bz #20357)
During the sincos consolidation I made two mistakes, one was a logical
error due to which cos(0x1.8475e5afd4481p+0) returned
sin(0x1.8475e5afd4481p+0) instead.
The second issue was an error in negating inputs for the correct
quadrants for sine. I could not find a suitable test case for this
despite running a program to search for such an input for a couple of
hours.
Following patch fixes both issues. Tested on x86_64. Thanks to Matt
Clay for identifying the issue.
[BZ #20357]
* sysdeps/ieee754/dbl-64/s_sin.c (sloww): Fix up condition
to call __mpsin/__mpcos and to negate values.
* math/auto-libm-test-in: Add test.
* math/auto-libm-test-out: Regenerate.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

Fix cos computation for multiple precision fallback (bz #20357)
During the sincos consolidation I made two mistakes, one was a logical
error due to which cos(0x1.8475e5afd4481p+0) returned
sin(0x1.8475e5afd4481p+0) instead.
The second issue was an error in negating inputs for the correct
quadrants for sine. I could not find a suitable test case for this
despite running a program to search for such an input for a couple of
hours.
Following patch fixes both issues. Tested on x86_64. Thanks to Matt
Clay for identifying the issue.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]
The compiled tests no longer refer to the mallopt symbol
from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

localedata: bs_BA: fix yesexpr/noexpr [BZ #20974]
Both regexes end with a "*." which means the previous match can be
omitted, and then the . allows them to match any input at all.
This means tools like coreutils' `rm -i` will always delete things
when prompted because the yesexpr regex matches all inputs (even
the negative ones).

Fix cos computation for multiple precision fallback (bz #20357)
During the sincos consolidation I made two mistakes, one was a logical
error due to which cos(0x1.8475e5afd4481p+0) returned
sin(0x1.8475e5afd4481p+0) instead.
The second issue was an error in negating inputs for the correct
quadrants for sine. I could not find a suitable test case for this
despite running a program to search for such an input for a couple of
hours.
Following patch fixes both issues. Tested on x86_64. Thanks to Matt
Clay for identifying the issue.
[BZ #20357]
* sysdeps/ieee754/dbl-64/s_sin.c (sloww): Fix up condition
to call __mpsin/__mpcos and to negate values.
* math/auto-libm-test-in: Add test.
* math/auto-libm-test-out: Regenerate.

Compile glibc with the attached patch and install it. The system will no
longer boot because of errors like this one:
# /sbin/init
/sbin/init: relocation error: /usr/lib/systemd/libsystemd-shared-232.so: symbol
write, version GLIBC_2.2.5 not defined in file libpthread.so.0 with link time
reference
I'm not sure if this link failure is a dynamic linker bug. The symbol
versioning specification is ambiguous whether the soname in the version counts
for symbol resolution.

I think that's at best left unspecified. For the kernel implementation, the
behavior depends on the file system.

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

Fix localplt test breakage with new readelf
Since 2014-11-24 binutils git commit bb4d2ac2, readelf has appended
the symbol version to symbols shown in reloc dumps.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]
The compiled tests no longer refer to the mallopt symbol
from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

and can now be merged. Verified that the only generated code change
on x86_64 is that of line numbers in asserts, like so:

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

Fix localplt test breakage with new readelf
Since 2014-11-24 binutils git commit bb4d2ac2, readelf has appended
the symbol version to symbols shown in reloc dumps.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]
The compiled tests no longer refer to the mallopt symbol
from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

Fix localplt test breakage with new readelf
Since 2014-11-24 binutils git commit bb4d2ac2, readelf has appended
the symbol version to symbols shown in reloc dumps.

* scripts/localplt.awk: Strip off symbol version.
* NEWS: Mention bug fix.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]
The compiled tests no longer refer to the mallopt symbol
from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

and can now be merged. Verified that the only generated code change

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

Fix localplt test breakage with new readelf
Since 2014-11-24 binutils git commit bb4d2ac2, readelf has appended
the symbol version to symbols shown in reloc dumps.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]
The compiled tests no longer refer to the mallopt symbol
from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]
The compiled tests no longer refer to the mallopt symbol
from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]
The compiled tests no longer refer to the mallopt symbol
from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]

from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]

from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

malloc: Run tests without calling mallopt [BZ #19469]

from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

This seems to have been left behind as an artifact of some old changes
and can now be merged. Verified that the only generated code change
on x86_64 is that of line numbers in asserts, like so:

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

Extend local PLT reference check
On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with
R_*_GLOB_DAT relocation against the same symbol. This patch extends
local PLT reference check to support alternate relocations.
[BZ #18078]
* scripts/check-localplt.awk: Support alternate relocations.
* scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL
sections.
* sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and
malloc entries with + REL R_386_GLOB_DAT.
* sysdeps/x86_64/localplt.data: New file.

malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

nptl/tst-tls3-malloc: Force freeing of thread stacks
It turns out that due to the reduced stack size in tst-tls3 and the
(fixed) default stack cache size, allocated TLS variables are never
freed, so the test coverage for tst-tls3-malloc is less than complete.
This change increases the thread stack size for tst-tls3-malloc only,
to make sure thread stacks and TLS variables are freed.

explicitly, which is fine.)

elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]
Instead, call malloc and explicitly align the pointer.
There is no external location to store the original (unaligned)
pointer, and this commit increases the allocation size to store
the pointer at a fixed location relative to the TCB pointer.
The manual alignment means that some space goes unused which
was previously made available for subsequent allocations.
However, in the TLS_DTV_AT_TP case, the manual alignment code
avoids aligning the pre-TCB to the TLS block alignment. (Even
while using memalign, the allocation had some unused padding
in front.)
This concludes the removal of memalign calls from the TLS code,
and the new tst-tls3-malloc test verifies that only core malloc
routines are used.

elf: Avoid using memalign for TLS allocations [BZ #17730]
Instead of a flag which indicates the pointer can be freed, dtv_t
now includes the pointer which should be freed. Due to padding,
the size of dtv_t does not increase.
To avoid using memalign, the new allocate_dtv_entry function
allocates a sufficiently large buffer so that a sub-buffer
can be found in it which starts with an aligned pointer. Both
the aligned and original pointers are kept, the latter for calling
free later.

malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:
(M1) malloc arena locks (in the registered fork handler)
(M2) libio list lock
A thread F invoking flush (NULL) would acquire locks in this order:
(F1) libio list lock
(F2) individual _IO_FILE locks
A thread G running getdelim would use this order:
(G1) _IO_FILE lock
(G2) malloc arena lock
After executing (M1), (F1), (G1), none of the threads can make progress.
This commit changes the fork lock order to:
(M'1) libio list lock
(M'2) malloc arena locks
It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

malloc: Fix list_lock/arena lock deadlock [BZ #19182]
* malloc/arena.c (list_lock): Document lock ordering requirements.
(free_list_lock): New lock.
(ptmalloc_lock_all): Comment on free_list_lock.
(ptmalloc_unlock_all2): Reinitialize free_list_lock.
(detach_arena): Update comment. free_list_lock is now needed.
(_int_new_arena): Use free_list_lock around detach_arena call.
Acquire arena lock after list_lock. Add comment, including FIXME
about incorrect synchronization.
(get_free_list): Switch to free_list_lock.
(reused_arena): Acquire free_list_lock around detach_arena call
and attached threads counter update. Add two FIXMEs about
incorrect synchronization.
(arena_thread_freeres): Switch to free_list_lock.
* malloc/malloc.c (struct malloc_state): Update comments to
mention free_list_lock.

I've always wondered about this, and the truth is I consider the binding we
have today to be overspecified.
I think that any write@@GLIBC_2.2.5 should be able to resolve
write@GLIBC_2.2.5, not just he one that came from the library that provided the
original link-time reference (encoded in .gnu.version_r).
However, Ulrich's original design seems to explicitly call this out:
~~~
This has to be done by walking through all the entries of the loading
object's Elfxx_Verneed array and examining whether the loaded object's
Elfxx_Verdef array contains an appropriate version definition. Both,
the version definition and the version requirement, are identified by
strings. In both cases the structures contain beside the string (or
string references) also ELF hashing values which can be compared
before making the actual string comparison.
~~~
So there is an implicit binding of <symbol> + <version> to <soname> that
happens.
The only rationale given is:
~~~
This way it is possible to recognize libraries which
are too old and don't contain all the symbols or contain incompatible
implementations. Without this kind of test one could end up with
runtime errors which don't provide helpful information.
~~~
It also means you can never move the versioned symbol to another shared object.

Bug 20116: Fix use after free in pthread_create()
The commit documents the ownership rules around 'struct pthread' and
when a thread can read or write to the descriptor. With those ownership
rules in place it becomes obvious that pd->stopped_start should not be
touched in several of the paths during thread startup, particularly so
for detached threads. In the case of detached threads, between the time
the thread is created by the OS kernel and the creating thread checks
pd->stopped_start, the detached thread might have already exited and the
memory for pd unmapped. As a regression test we add a simple test which
exercises this exact case by quickly creating detached threads with
large enough stacks to ensure the thread stack cache is bypassed and the
stacks are unmapped. Before the fix the testcase segfaults, after the
fix it works correctly and completes without issue.
For a detailed discussion see:
https://www.sourceware.org/ml/libc-alpha/2017-01/msg00505.html

Bug ID: 21091
Summary: Unexpected collation in ja_JP.UTF-8 probably due to
unsupported blocks
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: mh-sourceware at glandium dot org
CC: libc-locales at sourceware dot org
Target Milestone: ---
I was doing some scripting around some subset of the data in
https://github.com/cjkvi/cjkvi-ids/blob/master/ids.txt. I ended up doing things
like sort | uniq -d, both of which use strcoll.
My system locale is ja_JP.UTF-8, and that led to surprising results. I realize
what my intent was actually not to follow collation rules, but that still left
me wondering if collation was right in glibc.
So I created a LD_PRELOAD library that redirects strcoll to ICU's ucol_strcoll
and compared the outputs. They were very different.
So I dug further, and found that:
All characters in CJK Unified Ideographs Extension A are considered equal.
All characters in CJK Unified Ideographs Extension B are considered equal.
All characters in CJK Unified Ideographs Extension C are considered equal.
All characters in CJK Unified Ideographs Extension D are considered equal.
All characters in CJK Unified Ideographs Extension E are considered equal.
All characters in CJK Radicals Supplement are considered equal.
All characters in Kangxi Radicals are considered equal.
All characters in CJK Strokes are considered equal.
All characters in Enclosed CJK Letters and Months are considered equal.
All characters in CJK Compatibility are considered equal.
All characters in CJK Compatibility Ideographs are considered equal.
All characters in CJK Compatibility Forms are considered equal.
All characters in Enclosed Ideographic Supplement are considered equal.
All characters in CJK Compatibility Ideographs Supplement are considered equal.
More than that, all the characters in the blocks above with codepoints below
0x10000 are considered equals, and all the characters in the blocks above with
codepoints above 0x10000 are considered equal.
All in all, it would seem all unsupported characters in the BMP are equal, and
all unsupported characters in other unicode planes are equal.
With new unicode versions adding new characters, it seems to me it would be
better if unsupported characters were considered different as a general rule.
Obviously, it would be better if the above blocks were supported.
(This is with libc 2.24-9 from Debian)

Mmmm in fact, it looks like some characters in the CJK Unified Ideographs block
are equal to those unsupported characters in other BMP blocks.

Bug ID: 21092
Summary: mbsnrtowcs: *src is not left pointing to the invalid
multibyte sequence when dest is NULL
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: igor.liferenko at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
The following examples demonstrate the difference when dest is NULL and dest
is not NULL.
According to this bugreport[1], there are two possible cases:
1) incomplete multibyte character is at the end of input buffer *)
2) incomplete multibyte character is not at the end of input buffer *)
*) - end of buffer is determined by nms argument.
The examples 1.1 and 2.1 demonstrate that when dest is NULL, *src is
not changed.
The examples 1.2 and 2.2 demonstrate that when dest is not NULL, *src is
correctly changed.
In the examples the following UTF-8 sequences are used:
\320 = incomplete
\321\215 = U+044D (CYRILLIC SMALL LETTER E)
\321\216 = U+044E (CYRILLIC SMALL LETTER YU)
Example 1.1 (at the end of buffer, dest is NULL):
#include <locale.h>
#include <wchar.h>
#include <stdio.h>
int main(void)
{
setlocale(LC_CTYPE, "en_US.UTF-8");
char *s = "\321\216\320";
const char *x = s;
printf("status: %d\n", mbsnrtowcs(NULL,&x,3,0,NULL));
perror(NULL);
printf("ori=%p\nnew=%p\n",(void *)s,(void *)x);
return 0;
}
Output 1.1:
status: 1
Success
ori=0x56337c86d910
new=0x56337c86d910
Example 2.1 (not at the end of buffer, dest is NULL):
#include <locale.h>
#include <wchar.h>
#include <stdio.h>
int main(void)
{
setlocale(LC_CTYPE, "en_US.UTF-8");
char *s = "\321\216\320\321\215";
const char *x = s;
printf("status: %d\n", mbsnrtowcs(NULL,&x,5,0,NULL));
perror(NULL);
printf("ori=%p\nnew=%p\n",(void *)s,(void *)x);
return 0;
}
Output 2.1:
status: -1
Invalid or incomplete multibyte or wide character
ori=0x55ad82792910
new=0x55ad82792910
Example 1.2 (at the end of buffer, dest is not NULL):
#include <locale.h>
#include <wchar.h>
#include <stdio.h>
int main(void)
{
setlocale(LC_CTYPE, "en_US.UTF-8");
char *s = "\321\216\320";
const char *x = s;
wchar_t wcs[3];
printf("status: %d\n", mbsnrtowcs(wcs,&x,3,3,NULL));
perror(NULL);
printf("ori=%p\nnew=%p\n",(void *)s,(void *)x);
return 0;
}
Output 1.2:
status: 1
Success
ori=0x556497c29980
new=0x556497c29983
Example 2.2 (not at the end of buffer, dest is not NULL):
#include <locale.h>
#include <wchar.h>
#include <stdio.h>
int main(void)
{
setlocale(LC_CTYPE, "en_US.UTF-8");
char *s = "\321\216\320\321\215";
const char *x = s;
wchar_t wcs[5];
printf("status: %d\n", mbsnrtowcs(wcs,&x,5,5,NULL));
perror(NULL);
printf("ori=%p\nnew=%p\n",(void *)s,(void *)x);
return 0;
}
Output 2.2:
status: -1
Invalid or incomplete multibyte or wide character
ori=0x55bb1aa98980
new=0x55bb1aa98982

Summary: mbsnrtowcs: *src is not left pointing to the next
multibyte sequence to be converted when input buffer
ends with incomplete multibyte sequence
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: igor.liferenko at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
According to this bugreport[1], if the input buffer ends (end of buffer is
determined by nms argument) with an incomplete multibyte sequence, mbsnrtowcs()
stops conversion before it.
The words "stops conversion" mean that the next byte is not processed.
Thus, *src must be left pointing to the next byte, before which the conversion
was stopped.
But, as can be seen from the following example, mbsnrtowcs() tries to do
further
conversion (and advances *src to point after incomplete multibyte character) -
it does not actually *stop* the conversion, which is a contradiction.
In the example the following UTF-8 sequences are used:
\320 = incomplete
\321\215 = U+044D (CYRILLIC SMALL LETTER E)
#include <locale.h>
#include <wchar.h>
#include <stdio.h>
int main(void)
{
setlocale(LC_CTYPE, "en_US.UTF-8");
char *s = "\321\215\320";
const char *x = s;
wchar_t wcs[3];
printf("status: %d\n", mbsnrtowcs(wcs,&x,3,3,NULL));
perror(NULL);
printf("ori=%p\nnew=%p\n",(void *)s,(void *)x);
return 0;
}
Output:
status: 1
Success
ori=0x556497c29980
new=0x556497c29983
As the output confirms, conversion was stopped before incomplete multibyte
sequence. The problem is, that *src does not point to the next multibyte
sequence to be converted (0x556497c29982).
Compare this with the following example, which also does not set errno to
EILSEQ (Success), and returns the same number of successfully converted
characters (status: 1). But this time *src is left pointing to the next
multibyte sequence to be converted:
#include <locale.h>
#include <wchar.h>
#include <stdio.h>
int main(void)
{
setlocale(LC_CTYPE, "en_US.UTF-8");
char *s = "\321\215";

--- Comment #2 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
For 2.25 GLIBC has fixed some issues (BZ#17730, BZ#20432, BZ#20432) to support
and simplify both dynamic and malloc interposition. There is no need to known
glibc internal symbols neither interpose them to actually interpose the malloc
on both glibc and loader (check malloc/tst-interpose-* tests).
It is, however, non compatible solutions and some old releases do not support
these fixes (I have backported them to my own branchs, linaro/2.21/master and
linaro/2.23/master, so you might check what is required to interpose them).
We can backport them to old releases branches so static allocation is correctly
supported, however malloc hooks will not be reverted since they are, as you
correctly pointed out, a deficient API with many issues and current approach
solves these issues.

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
I think this change is reasonable, the only details I am not sure is which
ROUNDS_MAX would the most suitable, mainly on slower CPUs. On ARMv7 Cortex-A15
using 9999999 rounds it took about 20s, which is high but still manageable.
Can you send this patch upstream?

"Can you send this patch upstream?"
What do you mean by this? Isn't this the official glibc bug tracker, thus
upstream?

Patch discussions are not done in bugtracker, but rather on libc-alpha [1]. By
send this upstream I mean send a complete patch for libc mailist.

Please report this on https://bugzilla.redhat.com/, with a exact glibc version
number. This could be a problem with the downstream backport.
Please also include backtraces from all threads in the report. Thanks.

--- Comment #18 from H.J. Lu <hjl.tools at gmail dot com> ---
Also
[hjl@gnu-6 pr21041d]$ gcc -o y main.o libfoo.so libxxx.so libbar1.so
-Wl,-rpath,.
[hjl@gnu-6 pr21041d]$ ./y
[hjl@gnu-6 pr21041d]$
The difference is ld.so checks libxxx.so before libbar1.so.

--- Comment #19 from H.J. Lu <hjl.tools at gmail dot com> ---
dl-lookup.c has
skip:
/* If this current map is the one mentioned in the verneed entry
and we have not found a weak entry, it is a bug. */
if (symidx == STN_UNDEF && version != NULL && version->filename != NULL
&& __glibc_unlikely (_dl_name_match_p (version->filename, map)))
return -1;
But there is no requirement for that the symbol definition at run-time
must come from the same shared object at link-time.

Bug ID: 21094
Summary: cosf(1.57079697) has 3 ulp error on targets where the
generic c code is used
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: nszabolcs at gmail dot com
Target Milestone: ---
at x=1.57079697, that is 0x3fc90fe0,
cosf(x) returns -0x1.5777ap-21 instead of -0x1.5777a6p-21
because in sysdeps/ieee754/flt-32/e_rem_pio2f.c
if((ix&0xfffffff0)!=0x3fc90fd0) { /* 24+24 bit pi OK */
...
} else { /* near pi/2, use 24+24+24 bit pi */
...
}
the "near pi/2" special case is not applied.
other than at +-1.57079697, cosf seems to have <= 1 ulp
error compared to cos.

commit 02b78ff749f0c88771713368dbb2a09b1979814f
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Mon Jan 30 10:59:15 2017 -0800
Add VZEROUPPER to memset-vec-unaligned-erms.S [BZ #21081]
Since memset-vec-unaligned-erms.S has VDUP_TO_VEC0_AND_SET_RETURN at
function entry, memset optimized for AVX2 and AVX512 will always use
ymm/zmm register. VZEROUPPER should be placed before ret in
L(stosb):
movq %rdx, %rcx
movzbl %sil, %eax
movq %rdi, %rdx
rep stosb
movq %rdx, %rax
ret
since it can be reached from
L(stosb_more_2x_vec):
cmpq $REP_STOSB_THRESHOLD, %rdx
ja L(stosb)
[BZ #21081]
* sysdeps/x86_64/multiarch/memset-vec-unaligned-erms.S
(L(stosb)): Add VZEROUPPER before ret.

--- Comment #2 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
The most recent SPARC release results reported by Adhemerval on
https://sourceware.org/glibc/wiki/Release/2.25 do not show this failing. Nor
do Aurelien's at
https://sourceware.org/glibc/wiki/Release/2.22 so presuming fixed (possibly
through changes in GCC or elsewhere) in the absence of any recent reports.

commit ed8d5ffd0a14e84298a15ae2ec9b799010166b28
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Thu Feb 2 15:48:06 2017 +0530
Drop GLIBC_TUNABLES for setxid programs when tunables is disabled (bz
#21073)
A setxid program that uses a glibc with tunables disabled may pass on
GLIBC_TUNABLES as is to its child processes. If the child process
ends up using a different glibc that has tunables enabled, it will end
up getting access to unsafe tunables. To fix this, remove
GLIBC_TUNABLES from the environment for setxid process.
* sysdeps/generic/unsecvars.h: Add GLIBC_TUNABLES.
* elf/tst-env-setuid-tunables.c
(test_child_tunables)[!HAVE_TUNABLES]: Verify that
GLIBC_TUNABLES is removed in a setgid process.

commit 8b9e9c3c0bae497ad5e2d0ae2f333f62feddcc12
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Thu Feb 2 15:46:01 2017 +0530
tunables: Fix environment variable processing for setuid binaries (bz
#21073)
Florian Weimer pointed out that we have three different kinds of
environment variables (and hence tunables):
1. Variables that are removed for setxid processes
2. Variables that are ignored in setxid processes but is passed on to
child processes
3. Variables that are passed on to child processes all the time
Tunables currently only does (2) and (3) when it should be doing (1)
for MALLOC_CHECK_. This patch enhances the is_secure flag in tunables
to an enum value that can specify which of the above three categories
the tunable (and its envvar alias) belongs to.
The default is for tunables to be in (1). Hence, all of the malloc
tunables barring MALLOC_CHECK_ are explicitly specified to belong to
category (2). There were discussions around abolishing category (2)
completely but we can do that as a separate exercise in 2.26.
Tested on x86_64 to verify that there are no regressions.
[BZ #21073]
* elf/dl-tunable-types.h (tunable_seclevel_t): New enum.
* elf/dl-tunables.c (tunables_strdup): Remove.
(get_next_env): Also return the previous envp.
(parse_tunables): Erase tunables of category
TUNABLES_SECLEVEL_SXID_ERASE.
(maybe_enable_malloc_check): Make MALLOC_CHECK_
TUNABLE_SECLEVEL_NONE if /etc/setuid-debug is accessible.
(__tunables_init)[TUNABLES_FRONTEND ==
TUNABLES_FRONTEND_valstring]: Update GLIBC_TUNABLES envvar
after parsing.
[TUNABLES_FRONTEND != TUNABLES_FRONTEND_valstring]: Erase
tunable envvars of category TUNABLES_SECLEVEL_SXID_ERASE.
* elf/dl-tunables.h (struct _tunable): Change member is_secure
to security_level.
* elf/dl-tunables.list: Add security_level annotations for all
tunables.
* scripts/gen-tunables.awk: Recognize and generate enum values
for security_level.
* elf/tst-env-setuid.c: New test case.
* elf/tst-env-setuid-tunables: new test case.
* elf/Makefile (tests-static): Add them.

(In reply to Carlos O'Donell from comment #43)
> It sounds like you have a design in mind, please by all means start a wiki
How about the following design proposal:
just provide the raw gettid wrapper via some
system-specific header (like sys/* or asm/* I guess)
and keep thinking of further proposals about
making things generic.
By not exporting the raw wrapper you only force
people to use syscall(SYS_gettid), which is not
good at all. In the mean time, a wrapper exported
via system-specific headers does not obligate you
to any design restrictions or even doc writing.

--- Comment #4 from Carlos O'Donell <carlos at redhat dot com> ---
This affects aarch64, ppc64le, and ppc64.
I have tested Alex's fix on all 3 arches and it alloes tst-tls-manydynamic to
pass, as expected.
I am removing Alex's comments though since they need to be reworked to describe
a broader overview of the P&C aspects of TLS initialization across all of the
arches.

--- Comment #4 from ma.jiang at zte dot com.cn ---
(In reply to Florian Weimer from comment #3)
> We currently cannot use INTERNAL_SYSCALL in generic code, so this is more
> complicated than it looks.
Hi Florian,
Sorry for the delay, we got spring festival last week.
If we could not use INTERNAL_SYSCALL in libc-tls.c then I can finally
understand those comments in code now... But I still can not understand why
INTERNAL_SYSCALL can not be used here.
INTERNAL_SYSCALL is just a macro in sysdep.h, and have been used in many
generic routines
(nptl/nptl-init.c,sysdeps/unix/sysv/linux/clock_nanosleep.c,...). Moreover, I
have tried to add a static __sbrk (which used INTERNAL_SYSCALL) into
libc-tls.c. It seems all things are ok, no compiling errors or run-time errors.
By the way, there is another piece of code in my patch. It is about init_tls
in elf/rtld.c. This piece should be applicable , I suppose.

With “generic“, I meant “not Linux-specificâ€. INTERNAL_SYSCALL is specific to
Linux. Hurd uses something else. I don't know what the out-of-tree FreeBSD
port uses.

Bug ID: 21108
Summary: multithreaded setuid can silently fail on rt signal
exhaustion
Product: glibc
Version: 2.19
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: jannh at google dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Flags: security?
__nptl_setxid() signals threads using setxid_signal_thread(), which assumes
that the tgkill() syscall with the real-time signal SIGSETXID can only fail if
the target thread has not started yet or has exited. Actually, for realtime
signals, tgkill() can also fail if the per-user limit on pending signals has
been reached. This can be seen in the kernel sources, where tgkill() is handled
through the call chain
do_tkill->do_send_specific->do_send_sig_info->send_signal->__send_signal.
__send_signal sets the override_rlimit flag to 0 because the signal number is
>=SIGRTMIN, then passes that flag to __sigqueue_alloc(), which then refuses to
allocate a signal if RLIMIT_SIGPENDING has been reached by the current user (as
determined using the real uid). __send_signal() fails with error code -EAGAIN.
To reproduce:

err(1, "sigprocmask");
pid_t me = getpid();
int count = 0;
const union sigval val = {.sival_int = 0};
while (1) {
if (sigqueue(me, SIGRTMIN, val))
break;
count++;
}
if (errno == EAGAIN) {
printf("EAGAIN at %d\n", count);
while (1) pause();
}
errx(1, "sigqueue");
}
$ cat threaded_setuid.c
#include <pthread.h>
#include <unistd.h>
#include <stdio.h>
#include <err.h>
void *thread_fn(void *arg) {
while (1) pause();
}
int main(void) {
pthread_t thread;
pthread_create(&thread, NULL, thread_fn, NULL);
if (setuid(getuid()))
err(1, "setuid");
puts("done");
while (1) pause();
$ gcc -Wall -o starve starve.c -std=gnu99 && gcc -pthread -Wall -o
threaded_setuid threaded_setuid.c -std=gnu99 && sudo chown root:root
threaded_setuid && sudo chmod 4755 threaded_setuid

Tunables don't work on big-endian. The callback always receives a pointer to
tunable_t instead of the actual value. For example, tst-malloc-usable fails
due to this.

Thanks for your patient explanation. Now I fully understand the whole story.
I have updated my patch(see the attachment), which trap SIGSEGV and print
error strings. Could you take some time to review it?

--- Comment #2 from Florian Weimer <fweimer at redhat dot com> ---
The change in commit 718946816cf60374f9d8f674d3ed649fdb33205a has no effect
because of two bugs which cancel each other out: The svc_is_mapped condition is
inverted, and svc_is_mapped always returns false because the check is performed
after the service has already been unregistered. As a result, pmap_unset is
called unconditionally, as before.

Bug ID: 21116
Summary: Wrong jump address on ppc64le by using dlopen and
dlsym in glibc 2.17 and 2.24
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: ltc_mkpls at yahoo dot de
Target Milestone: ---
Created attachment 9795
--> https://sourceware.org/bugzilla/attachment.cgi?id=9795&action=edit
Minimal Example for the dlopen bug.
During the development of a plugin framework for LAPACK functions I ran into
trouble with dlopen/dlsym which seems to compute a wrong address or jump to a
wrong address. The problem setup is the following (as short description to the
attached code).
I open the LAPACK (at least version 3.6.1) library using dlopen and search for
the symbols "dgetrf", "dgetrf2" and "dgetf2" on start up of the application
using the attribute(constructor) mechanism. For each of the three symbols I
have a wrapping function with the exactly the same name and the same binary
interface. Running the code on x86-64 everything works fine. If I now switch to
ppc64le (OpenPower8 - triple: powerpc64le-linux-gnu) it crashes and I get the
following backtrace in gdb:
#0 0x000000000074696c in ?? ()

#15 0x0000000010000d70 in main (argc=2, argv=0x3ffffffff1d8) at

where in frame #0 the address 0x000000000074696c is wrong. Correct would be
0x00003fffb7f60c1c as in frame #2. With some work I found out that it seems
that inside the plt when the call is performed a wrong address is computed.
I tried the code on two different versions of glibc and gcc. The first one was
on a CentOS 7.3 with glibc 2.17 :
gcc -v :

Both system running with Linux 4.8.6-300.el7.centos.ppc64le. But a second the
confirmed that it also happens on 3.11 which originally shipped with CentOS.
The attached tar-ball contains the minimal-not-working example on my systems.
Using make it compiles LAPACK-3.6.1 and the example. By "make run" it executes
the example and "make gdb" starts the example in gdb.

One additional note. The dgetrf2 function in LAPACK is a recursive function.

One further bug in the descriptions. The correct address in frame #0 is
0x3fffb77212d8 which points to the dlaswp function inside LAPACK.

--- Comment #4 from grisu <ltc_mkpls at yahoo dot de> ---
The LD_PRELOAD mechanism is exacly what I want to avoid because I want to be
able to exchange the pointers and the dlopen handle to switch LAPACK at
runtime. Furthermore, on x86 and x86-64 it works without any problems.

Does it work if you use testrun.sh to run the test?
I wouldn't be surprised if the command you used attempts to run the test with a
mix of the installed and the built glibc, which is not supported.

Yes, it fails if I run "make check".
The command line above is just my clumsy attempt to reproduce it.
Is there a way to run a single test from the build directory?

Thanks for mentioning the recursion, it was helpful for identifying the root

This is a GCC code generation issue, affecting the POWER ELFv2 ABI:

--- Comment #6 from grisu <ltc_mkpls at yahoo dot de> ---
It seems that you are right. I compiled the same code again with the PGI
compiler and it works as expected. Than lets wait what happens on the gcc side
and thank you for you even shorter example.

Bug ID: 21119
Summary: Unify the pthread_mutex_t definitions
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: hyc at symas dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Currently the size of a pthread_mutex_t structure can be one of 3 different
sizes, depending on the CPU architecture and ABI. E.g., from
/usr/include/pthreadtypes.h:
#ifdef __x86_64__
# if __WORDSIZE == 64
# define __SIZEOF_PTHREAD_MUTEX_T 40
# else
# define __SIZEOF_PTHREAD_MUTEX_T 32
# endif
#else
# define __SIZEOF_PTHREAD_MUTEX_T 24
#endif
This limits the usefulness of process-shared mutexes, as they cannot safely be
used by both 32bit and 64bit processes at the same time.
It Would Be Nice if a cross-arch-compatible definition could be made. Since the
guts are all behind a futex syscall anyway this shouldn't be a huge problem,
should it?
Presumably this is also an issue for process-shared rwlocks.

For reference, this impairs cross-architecture use of LMDB on Linux/glibc, but
other platforms that LMDB supports don't have this problem.

Bug ID: 21120
Summary: glibc malloc is incompatible with GCC 7
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Target: i386
Flags: security-
GCC 7 changes the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as aligned
as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this one:
error: allocation function 0, size 144 not aligned to 16
We should increase the malloc alignment to 16, or ask GCC to revert the change.

Correct, per POSIX, to avoid errors, only AS-safe functions should be called.
I agree that QoI rules here and we could reset the lock.

Bug ID: 21127
Summary: printf functions can take much memory with %g when the
format precision is large
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: vincent-srcware at vinc17 dot net
Target Milestone: ---
On some easy cases, the printf functions take much memory when the precision in
the format string is large. For instance:
#include <stdio.h>
int main (void)
{
for (int i = 20; i > 0; i--)
printf ("%.300000000g\n", i + 0.5);
return 0;
}
The printf function is fast on 20.5 to 10.5, but starting with 9.5, it becomes
very slow and takes much memory (about 1 GB on my Debian Linux x86_64 machine
with libc6 2.24), while these cases are very similar.

commit b987917e6aa7ffe2fd74f0b6a989438e6edd0727

ldbl-128: Fix y0 and y1 for -Inf input [BZ #21130]
The Bessel functions of the second type (Yn) are not defined for
negative input and should return NAN with the "invalid" exception
raised, in these cases. However, current code checks for infinity and
return zero, regardless of the sign. This error is exposed for long
double when linking with -lieee. Without this flag, the error is not
exposed, because the wrappers for these functions, which use
__kernel_standard functionality, return the correct value.
Tested for powerpc64le.
[BZ #21130]
* sysdeps/ieee754/ldbl-128/e_j0l.c (__ieee754_y0l): Return NAN
with the "invalid" exception raised when x is -Inf.
* sysdeps/ieee754/ldbl-128/e_j1l.c (__ieee754_y1l): Likewise.

--- Comment #2 from Florian Weimer <fweimer at redhat dot com> ---
This is very difficult to fix because existing binaries have conflicting
requirements for data structure layout due to compiled-in static initializers.
Maybe the way forward here is a public futex interface with extended ABI
compatibility guarantees.

--- Comment #3 from Torvald Riegel <triegel at redhat dot com> ---
I don't that a exposing futexes would be the right approach. It is too
low-level an interface for many clients, I believe. While currently, pthreads
mutexes will accomplish a lot through use of futexes, this isn't necessarily
going to remain that way to the same extent.
Howard, have you tried using semaphores more extensively?
Regarding 32b/64b compatibility: Maybe this can be considered for something
like a semaphore; but even there this is not quite trivial.

Bug ID: 21160
Summary: nptl: Data races in PTHREAD_PRIO_PROTECT
implementation
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P3
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Flags: security-
To speed up scheduling priority adjustments for PTHREAD_PRIO_PROTECT mutexes,
glibc maintains a cache of the kernel scheduling policy in the TCB. Flags are
used to indicate if the cache is initialized, in a variant of the
double-checked locking idiom.
However, as can be seen in the implementation of __pthread_current_priority,
the flags and the cached values are accessed without atomics:
int
__pthread_current_priority (void)
{
struct pthread *self = THREAD_SELF;
if ((self->flags & (ATTR_FLAG_POLICY_SET | ATTR_FLAG_SCHED_SET))
== (ATTR_FLAG_POLICY_SET | ATTR_FLAG_SCHED_SET))
return self->schedparam.sched_priority;
int result = 0;
/* See CREATE THREAD NOTES in nptl/pthread_create.c. */
lll_lock (self->lock, LLL_PRIVATE);
Once the flag is set, subsequent updates to the cached values are not guarded
against data races, either.
We need to evaluate if we actually need the cache for performance reasons, and
if yes, we should always initialize it (doing away with the flags) and use
atomics to access the values. As far as I can tell, the values fit in machine
words, so this should not be a problem.

Furthermore, it seems that calling pthread_getschedparam on a thread can
interfere with the PTHREAD_PRIO_PROTECT algorithm because of this lock.

Bug ID: 21161
Summary: [PATCH] fix typo in manual/arith.texi on strtoul
prototype
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: manual
Assignee: unassigned at sourceware dot org
Reporter: vincent-srcware at vinc17 dot net
CC: mtk.manpages at gmail dot com, roland at gnu dot org
Target Milestone: ---
Created attachment 9827
--> https://sourceware.org/bugzilla/attachment.cgi?id=9827&action=edit
patch fixing the typo
In manual/arith.texi of the git repository, the first argument of strtoul is
incorrect: it has "retrict" instead of "restrict", i.e.
@deftypefun {unsigned long int} strtoul (const char *retrict @var{string}, char
**restrict @var{tailptr}, int @var{base})
should be:
@deftypefun {unsigned long int} strtoul (const char *restrict @var{string},
char **restrict @var{tailptr}, int @var{base})
I've attached a patch.

Bug ID: 21163
Summary: Assertion failure in pop_fail_stack when executing a
malformed regexp
Product: glibc
Version: 2.24
Status: NEW
Severity: normal
Priority: P2
Component: regex
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Flags: security-
Debian bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=779392
Reproducer from the Debian bug:
#include <assert.h>
#include <regex.h>
#include <stdio.h>
int main(int argc, char **argv)
{
int rc;
regex_t preg;
regmatch_t pmatch[2];
rc = regcomp(&preg, "()*)|\\1)*", REG_EXTENDED);
assert(rc == 0);
regexec(&preg, "", 2, pmatch, 0);
regfree(&preg);
return 0;
}
This was assigned CVE-2015-8985 even though it is debatable whether this is a
security bug.

commit 4918e5f4cd63290bb0b2c614f52092ca6a779126
Author: Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
Date: Sun Feb 12 22:36:27 2017 -0200
Fix y0 and y1 exception handling for zero input [BZ #21134]
The Bessel functions of the second type (Yn) should raise the "divide
by zero" exception when input is zero (both positive and negative).
Current code gives the right output, but fails to set the exception.
This error is exposed for float, double, and long double when linking
with -lieee. Without this flag, the error is not exposed, because the
wrappers for these functions, which use __kernel_standard
functionality, set the exception as expected.
Tested for powerpc64le.
[BZ #21134]
* sysdeps/ieee754/dbl-64/e_j0.c (__ieee754_y0): Raise the
"divide by zero" exception when the input is zero.
* sysdeps/ieee754/dbl-64/e_j1.c (__ieee754_y1): Likewise.
* sysdeps/ieee754/flt-32/e_j0f.c (__ieee754_y0f): Likewise.
* sysdeps/ieee754/flt-32/e_j1f.c (__ieee754_y1f): Likewise.
* sysdeps/ieee754/ldbl-128/e_j0l.c (__ieee754_y0l): Likewise.
* sysdeps/ieee754/ldbl-128/e_j1l.c (__ieee754_y1l): Likewise.

Bug ID: 21171
Summary: log10, log2 and lgamma
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: tuliom at linux dot vnet.ibm.com
Target Milestone: ---
This can be reproduced after applying the following patch:
https://sourceware.org/ml/libc-alpha/2017-02/msg00241.html
Or using the branch tuliom/float128 in a powerpc64le machine.
It affects float, double and long double. I tested on powerpc, powerpc64,
powerpc64le and x86_64.
In the float128 branch it also affects _Float128 on powerpc64le.
The following is a fragment of the affected functions:
Failure: Test: log10_downward (0)
Result:
is: inf inf
should be: -inf -inf
infinity has wrong sign.
Failure: Test: log10_downward (-0)
Result:
is: inf inf
should be: -inf -inf
infinity has wrong sign.
Failure: Test: log2_downward (0)
Result:
is: inf inf
should be: -inf -inf
infinity has wrong sign.
Failure: Test: log2_downward (-0)
Result:
is: inf inf
should be: -inf -inf
infinity has wrong sign.
Failure: Test: lgamma (-max_value)
Result:
is: -inf -inf
should be: inf inf
infinity has wrong sign.
Failure: Test: lgamma_downward (-max_value)
Result:
is: -inf -inf
should be: inf inf
infinity has wrong sign.
Failure: Test: lgamma_towardzero (-max_value)
Result:
is: -inf -inf
should be: inf inf
infinity has wrong sign.
Failure: Test: lgamma_upward (-max_value)
Result:
is: -inf -inf
should be: inf inf

Bug ID: 21172
Summary: error: ‘__EI__libc_intl_domainname’ aliased to
undefined symbol ‘__GI__libc_intl_domainname’
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: ajstewart426 at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
I'm trying to build glibc 2.25 with GCC 6.1.0 on CentOS 6.8, x86_64. I'm
building my own binutils 2.27 and linux kernel headers from 4.9.10.
Unfortunately, `make` is crashing with the following error message:
./../include/libc-symbols.h:440:26: error: ‘__EI__libc_intl_domainname’ aliased
to undefined symbol ‘__GI__libc_intl_domainname’
extern __typeof (name) __EI_##name \
^
I've tried dozens of combinations of `configure` flags recommended by other
package managers, but with no luck. Any idea what is going wrong? Let me know
if you need any more information to diagnose the problem.

--- Comment #1 from Igor Liferenko <igor.liferenko at gmail dot com> ---
Let me pose the problem in another way:
The problem here is not that *src is changed incorrectly - according
to bugreport[1] it is changed correctly.
The problem here is that in the first example it is an incomplete multibyte
sequence and mbsnrtowcs() *must exit with error*, but it exits with success.

--- Comment #2 from Igor Liferenko <igor.liferenko at gmail dot com> ---
I would like to add here rationale for such behavior, as I understand it:
If conversion is stopped because end of buffer is reached, mbsnrtowcs() does
not know if there is continuation or not - it cannot know (without reading
further bytes) if it is incorrect sequence or it is incomplete sequence (which
may be correct, and also may be incorrect).

It may not be a bug that mbsnrtowcs() does not change *src when dest is NULL.
But to be sure, it is necessary to find out whether this is described in the
standard...

powerpc64le: Enable float128
Add ulps for the float128 type, bits/floatn.h, and float128-abi.h.
Likewise, sqrt is not implemented in libgcc. The sfp-machine.h
header is taken from libgcc, and used to build a P7/P8 soft-fp
sqrtf128.
TODO: ldouble seems to have gotten worse. Did I break something?

powerpc64le: Require gcc >= 6.2 for powerpc64le
On powerpc64le, support for __float128 will start to be built by default,
which requires gcc versions greater than or equal to 6.2.
Tested for ppc64 (still works with older compilers) and ppc64le.

powerpc64le: Create divergent sysdep directory for ppc64le.
float128 requires the seemingly trivial addition of the
ieee754/float128 sysdep. This requires creating a bunch
of submachine and cpu directories and Implies files which
just point towards their powerpc64 equivalent.
Tested on P7, P8, and generic ppc64le targets with and
without multiarch.

float128: Enable use of IEEE wrapper templates
The templates for the IEEE functions wrappers implement wrappers that
do not rely on _LIB_VERSION / matherr / __kernel_standard
functionality to set errno and fix the return value of the functions.
The wrappers are ready to be used by all floating-point types, however
they will first be used by float128, since the old wrappers for float,
double, and long double need to be first deprecated and versioned.
This commits defines __USE_WRAPPER_TEMPLATE to 1 for float128 files,
so that the new wrapper templates are used for this type.

This leverages the _Generic feature of C11 as __USE_FLOAT128

Add support for testing __STDC_WANT_IEC_60559_TYPES_EXT__
This is defined by TS 18661-3 for supporting the _FloatN

This will also implicitly enforce a minimum GCC 4.9. Given
the standard is a C11 derivative, it would seem reasonable
to assume a C11 compiler with _Generic support. This allows
for much simpler type classification macros which in theory
should be supported on any C11 compiler.

commit 3b33d6ed6096c1d20d05a650b06026d673f7399a
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>

Rework -fno-omit-frame-pointer support on i386
Commit 6b1df8b27f fixed the -OS build issue on i386 (BZ#20729) by
expliciting disabling frame pointer (-fomit-frame-pointer) on the
faulty objects. Although it does fix the issue, it is a subpar
workaround that adds complexity in build process (a rule for each
object to add the required compiler option and pontentially more
rules for objects that call {INLINE,INTERNAL}_SYSCALL) and does not
allow the implementations to get all the possible debug/calltrack
information possible (used mainly in debuggers and performance
measurement tools).
This patch fixes it by adding an explicit configure check to see
if -fno-omit-frame-pointer is set and to act accordingly (set or
not OPTIMIZE_FOR_GCC_5). The make rules is simplified and only
one is required: to add libc-do-syscall on loader due mmap
(which will be empty anyway for default build with
-fomit-frame-pointer).
Checked on i386-linux-gnu with GCC 6.2.1 with CFLAGS sets as
'-Os', '-O2 -fno-omit-frame-pointer', and '-O2 -fomit-frame-pointer'.
For '-Os' the testsuite issues described by BZ#19463 and BZ#15105
still applied.
It fixes BZ #21029, although it is marked as duplicated of #20729
(I reopened to track this cleanup).

Bug ID: 21182
Summary: segfaults with glibc-2.25 on i686
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: blog at pozimski dot eu
CC: drepper.fsp at gmail dot com
Target Milestone: ---
After Void Linux (http://www.voidlinux.eu/) updated their glibc package to
2.25, several users reported segmentation faults on the i686 platform. I
experienced them myself on a physical computer using an Intel Atom processor
(cpuinfo: https://owncloud.helmut-pozimski.de/index.php/s/3cOwICY2qNemETN ).
Specifically I saw segfaults while using ps, grep (on bigger files) or some
python relying software like salt-minion, in some instances gdb or kodi.
The segfaults seem to trace back to __memchr_sse2, this is a backtrace produced
via gdb while running grep on a 32M file:
https://owncloud.helmut-pozimski.de/index.php/s/03jB43CoEQtEXay
I tried to gather some more pieces of information together with one of the Void
developers, but was not able to produce a more detailed backtrace. The last
change in this function happened in git commit
https://sourceware.org/git/?p=glibc.git;a=commit;h=23d27709a423aec32821e9a5198a10267107bae2
, I tried to revert that one and recompile glibc. This seems to resolve the
issue at least one my machine.
It might also be relevant that no one managed to reproduce the issue inside a
VM yet, it seemingly is only reproducable on physical hardware and I don't know
if it affects all i686 era systems or only a certain range of Intel processors.
To reproduce the issue, run grep with any pattern on a larger file (in my tests
32K were not enough, several 100K produced a segfault and my /var/log/messages
which is 32M also did). Also just running "ps aux" on my system produced a
segfault as well as just starting either kodi or salt-minion. With gdb I do not
know under which circumstances it occurs, it wasn't really reliably
reproducable, just happened sometimes.

The Changelog contains the text "2017-01-17 Adhemerval Zanella ...".
Shouldn't the correct date be 2017-02-17?

--- Comment #2 from Fredrik Tolf <fredrik at dolda2000 dot com> ---
I am surprised by any lack of progress in this for almost five years. Is there
any reason why glibc hasn't added C11 threading support yet, or is it just that
no-one has any interest in it?

--- Comment #3 from Igor Liferenko <igor.liferenko at gmail dot com> ---
The problem here is that in example 1) below it is an incomplete multibyte
sequence and mbsnrtowcs() exits with success.
Compare it with example 2).
In the example the following UTF-8 sequences are used:
\320 = incomplete
\321\215 = U+044D (CYRILLIC SMALL LETTER E)
Example 1)
#include <locale.h>
#include <wchar.h>
#include <stdio.h>
int main(void)
{
setlocale(LC_CTYPE, "en_US.UTF-8");
char *s = "\321\215\320";
const char *x = s;
wchar_t wcs[3];
printf("status: %d\n", mbsnrtowcs(wcs,&x,3,3,NULL));
perror(NULL);
return 0;
}
Output:
status: 1
Success
The info from comment #1 is only relevant to how *src is changed, which is not
the issue here.
The problem is the incorrect return value and errno.

Bug ID: 21186
Summary: sem_getvalue() and sem_destroy() don't indicate EINVAL
when given an uninitialised semaphore
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: dhowells at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 9840
--> https://sourceware.org/bugzilla/attachment.cgi?id=9840&action=edit
Test program
sem_getvalue() and sem_destroy() don't return -1 and indicate EINVAL when given
a semaphore that hasn't been initialised by sem_init(), though the manual page
suggests that they should do so.
Attached is a test program for this. Give it zero arguments and it will do
sem_init()/sem_getvalue()/sem_destroy(). This should print:
After successful sem_init with value of 42 and successful sem_destroy,
sem_getvalue succeeded and retrieved the value = 42
which is what should happen.
Give it one argument and it will clear the semaphore with memset() and then
call sem_getvalue() without first initialising it. This prints:
For an uninitialized semaphore memory area, sem_getvalue succeeded and
retrieved the value = 0
when it should arguably set EINVAL and return -1.
Give it two arguments and it will call sem_getvalue() on the completely
uninitialised semaphore (and thus see random stack garbage). On my machine
producing something like:
For an uninitialized semaphore memory area, sem_getvalue succeeded
and retrieved the value = 4196368
Though I grant that this is a totally random effect depending on what's on the
stack at this point. However, it is arguable that here, we should set EINVAL
if we can (subject to the stack not coincidentally providing a false match).
The same goes for sem_destroy(). The manual page there indicates that
sem_destroy() should only be used on something initialised with sem_init() - or
an error should be generated.

The manual page simply lists EINVAL as an error code. That does not mean that
all invalid uses will result in that error code. In general, such a thing is
impossible to implement. All easy checks we could add to the code would be
invalid according to C semantics anyway.

I wonder if this is a known CPU erratum. The new code sequence does not look
problematic to me; I don't think it invokes implementation-defined instruction
behavior.

Please provide more information about the build environment. It is likely that
you are compiling with the wrong GCC version.

--- Comment #2 from Adam Stewart <ajstewart426 at gmail dot com> ---
Hi Florian,
I don't think it's a problem with the GCC version. According to the INSTALL
file, GCC 4.7 or newer is required, and GCC 6.3 is verified to work, so I
imagine GCC 6.1 should work as well. I also tried GCC 5.3.0 and that crashed
with the same error message.
As for more information about the build environment, what are you looking for?
Here are a couple more details:
$ uname -a
Linux blogin4 2.6.32-642.11.1.el6.x86_64 #1 SMP Fri Nov 18 19:25:05 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux
I'm using the Spack package manager to handle the installation. My
work-in-progress glibc package looks like:
https://github.com/LLNL/spack/pull/2631/files#diff-ea1dd14d89c4162e32c4003e808842ab
The configure args I used were stolen from other package managers. I don't
particularly need any of them if you think they may be causing problems. But I
tried building glibc without them and it gave the same error messages.
Let me know if there is any other information I can provide.

We have support for semaphores but they're not the preferred solution. Mainly
because there are race conditions in creating them when multiple processes open
the DB at the same time. Also because they have an independent lifetime; with
pshared mutexes living in the mmap'd lockfile they simply go away if a user
decides to delete the files.

--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
A complicated patch series can be expected to go through many cycles of
patch review and revision. At some point, detailed review comments were
provided for one patch series revision and updated patches did not follow.
I'm not sure what Adhemerval's plans are having picked up those patches
and put them on the azanella/c11-threads branch (or whether the patches
there do reflect all the review comments, or whether the various C11 DRs
relating to the definition of the C11 threads interfaces have been
reviewed to make sure the implementation properly respects the DR
resolutions).

I'd suggest providing preprocessed source for whatever .c file is
producing this error, along with the full compiler command line for
building it and the full glibc configure and make commands.

I'm not exactly a software developer, but let me know if I missed anything. The
configure and make commands are both in the "Output of configure and make"
attachment. I attached the file that it seems to be crashing on as well.

Please provide *preprocessed source*. That is, take the command to build
SYS_libc.os which produced the error, cd to the directory
($glibc_src/locale) in which that command was run, and run it manually
with -save-temps added, then provide the SYS_libc.i file which will have
been created (in the source directory).

commit 0a62a5c401cf5b4e79e8290e46ce36f4c6dd08da
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu Feb 12 23:05:37 2015 +0000
Fix powerpc software sqrt (bug 17964).
As Adhemerval noted in
<https://sourceware.org/ml/libc-alpha/2015-01/msg00451.html>, the
powerpc sqrt implementation for when _ARCH_PPCSQ is not defined is
inaccurate in some cases.
The problem is that this code relies on fused multiply-add, and relies
on the compiler contracting a * b + c to get a fused operation. But
sysdeps/ieee754/dbl-64/Makefile disables contraction for e_sqrt.c,
because the implementation in that directory relies on *not* having
contracted operations.
While it would be possible to arrange makefiles so that an earlier
sysdeps directory can disable the setting in
sysdeps/ieee754/dbl-64/Makefile, it seems a lot cleaner to make the
dependence on fused operations explicit in the .c file. GCC 4.6
introduced support for __builtin_fma on powerpc and other
architectures with such instructions, so we can rely on that; this
patch duly makes the code use __builtin_fma for all such fused
operations.
Tested for powerpc32 (hard float).
2015-02-12 Joseph Myers <joseph@codesourcery.com>
[BZ #17964]
* sysdeps/powerpc/fpu/e_sqrt.c (__slow_ieee754_sqrt): Use
__builtin_fma instead of relying on contraction of a * b + c.
(cherry picked from commit e8bd5286c68bc35be3b41e94c15c4387dcb3bec9)

What I was referring to is using semaphores instead of mutexes: start out with
one token available, consume a token when entering a criticla section, post a
token when exiting the critical section. Same lifetime as a mutex. But
semaphores are simpler than POSIX mutexes, so perhaps it may be easier for
implementations to make stronger guarantees for them.

I would have expected <https://sourceware.org/bugzilla/show_bug.cgi?id=14925>
to be fixed as a result of this update. As far as I can see it's not, so it
looks like some pieces were missed.

--- Comment #4 from Leah Neukirchen <leah at vuxu dot org> ---
I could reproduce this on Linux 4.4.6 with glibc 2.25 and gcc 6.3.0 directly
running on i686 "Intel(R) Atom(TM) CPU N270 @ 1.60GHz" (no PAE, 1G RAM).
Please consider the test case I just added. As you can see, addresses which
are less than 16 bytes off the end will result in searching pages behind the
buffer and make memchr return pointers outside of the area.
In a few cases, even different addresses are reported. (This was running inside
gdb.)
src = 0xb7fd5000 src+4096 = 0xb7fd6000
0 (nil)
1 (nil)
2 (nil)
3 (nil)
15 (nil)
16 (nil)
17 (nil)
4080 (nil)
4081 0xb7fda6ed
4082 0xb7fda6ed
4083 0xb7fda6ed
4084 0xb7fd90ff

Interestingly, valgrind takes no offense and returns (nil) for all inputs.
Merely reverting to glibc 2.24 fixes the issue, making it return (nil) for all
inputs, as expected.
This is a serious regression that makes many programs crash and/or corrupt
memory.

--- Comment #5 from Mike Frysinger <vapier at gentoo dot org> ---
our system was stuck on an old version: 3.12.20. we just recently were able to
upgrade it to 4.9.6 and it doesn't segfault anymore. so i guess there's not
much to be done here ? should we add a min kernel version check to glibc ?

--- Comment #1 from infinity0 at pwned dot gg ---
Someone told me about MALLOC_PERTURB_ (man mallopt) and that is really nice
already, however I think it would further benefit to have an actual build-time
option that results in the behaviour being compiled *into* the resulting
binary, as opposed to being set by the user. (Also the existence of
MALLOC_PERTURB_ could be much more widely advertised.)
The developers can test this and make sure their program doesn't break; most
users have less expertise to do this at run-time. Later, when 99% of programs
work (hopefully this is already the case today) the default can be switched to
ON.

Add VZEROUPPER to memset-vec-unaligned-erms.S [BZ #21081]
Since memset-vec-unaligned-erms.S has VDUP_TO_VEC0_AND_SET_RETURN at
function entry, memset optimized for AVX2 and AVX512 will always use
ymm/zmm register. VZEROUPPER should be placed before ret in
L(stosb):
movq %rdx, %rcx
movzbl %sil, %eax
movq %rdi, %rdx
rep stosb
movq %rdx, %rax
ret
since it can be reached from
L(stosb_more_2x_vec):
cmpq $REP_STOSB_THRESHOLD, %rdx
ja L(stosb)
[BZ #21081]
* sysdeps/x86_64/multiarch/memset-vec-unaligned-erms.S
(L(stosb)): Add VZEROUPPER before ret.

I wasn't able to get access to an Atom N270 machine so far. We need to
single-step through the new code and see what happens to the register contents,
to find the root cause of this bug. So unless you can do that (comparing it
with a working i386 machine), or someone can provide remote shell access to
such a machine, we are stuck.

I realized the machines where it works all use __memchr_sse2_bsf, but
I couldn't yet figure out how to force them to use __memchr_sse2 instead,
to make such a comparison trace.
Is there a trick to override the ifunc selection?
It would be nice if you could update the bug description to
"__memchr_sse2: regression in glibc-2.25 on i686"
or something, perhaps other people can find it easier then.

Good observation.
Currently, recompiling glibc is the only reliable option I know of. I used
this patch:
diff --git a/sysdeps/i386/i686/multiarch/memchr.S
b/sysdeps/i386/i686/multiarch/memchr.S
index bd0dace..4791d10 100644
--- a/sysdeps/i386/i686/multiarch/memchr.S
+++ b/sysdeps/i386/i686/multiarch/memchr.S
@@ -37,7 +37,7 @@ ENTRY(__memchr)

ret
-3: LOAD_FUNC_GOT_EAX (__memchr_sse2_bsf)
+3: LOAD_FUNC_GOT_EAX (__memchr_sse2)
ret
END(__memchr)
With this patch, I get this output from your test case:
0 (nil)
1 (nil)
2 (nil)
3 (nil)
15 (nil)
16 (nil)
17 (nil)

4083 0xf7e4128a
4084 0xf7e4128a
4094 0xf7e4128a
So it doesn't look like an Atom-specific CPU bug, but a generic issue in the
__memchr_sse2 function.

This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".
The branch, master has been updated
via d42eed4a044e5e10dfb885cf9891c2518a72a491 (commit)
from 963394a22b38c4ec92b6875a6c06d3b15d5c0d21 (commit)
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those

sunrpc: Avoid use-after-free read access in clntudp_call [BZ #21115]
After commit bc779a1a5b3035133024b21e2f339fe4219fb11c
(CVE-2016-4429: sunrpc: Do not use alloca in clntudp_call
[BZ #20112]), ancillary data is stored on the heap,
but it is accessed after it has been freed.
The test case must be run under a heap debugger such as valgrind
to observe the invalid access. A malloc implementation which
immediately calls munmap on free would catch this bug as well.

MALLOC_PERTURB_ can be set from inside the app using mallopt(), which is
documented ("man mallopt"). You can then wrap that in whatever user-visible
controls you want (#ifdef, command-line options, Makefiles, whatever).

Bug ID: 21204
Summary: sunrpc: svc_unregister is called for the main thread
only from __libc_freeres
Product: glibc
Version: 2.25
Status: NEW
Severity: minor
Priority: P3
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
svc_unregister is called for the main thread only from __libc_freeres. This
means that this call only happens when running under memory leak debuggers such
as valgrind. This is inconsistent with the intended use of __libc_freeres
(memory deallocations only) and may cause problems because at this point, large
parts of glibc have already been shut down.

sunrpc: Do not unregister services if not registered [BZ #5010]
The change in commit 718946816cf60374f9d8f674d3ed649fdb33205a
has no effect because of two bugs which cancel each other out:
The svc_is_mapped condition is inverted, and svc_is_mapped
always returns false because the check is performed after
the service has already been unregistered. As a result,
pmap_unset is called unconditionally, as before.

sunrpc: Improvements for UDP client timeout handling [BZ #20257]
This commit fixes various aspects in the UDP client timeout handling.
Timeouts are now applied in a more consistent fashion. Discarded UDP
packets no longer prevent the timeout from happening at all.

sunrpc: Avoid use-after-free read access in clntudp_call [BZ #21115]
After commit bc779a1a5b3035133024b21e2f339fe4219fb11c
(CVE-2016-4429: sunrpc: Do not use alloca in clntudp_call
[BZ #20112]), ancillary data is stored on the heap,
but it is accessed after it has been freed.
The test case must be run under a heap debugger such as valgrind
to observe the invalid access. A malloc implementation which
immediately calls munmap on free would catch this bug as well.
(cherry picked from commit d42eed4a044e5e10dfb885cf9891c2518a72a491)

sunrpc: Improvements for UDP client timeout handling [BZ #20257]
This commit fixes various aspects in the UDP client timeout handling.
Timeouts are now applied in a more consistent fashion. Discarded UDP
packets no longer prevent the timeout from happening at all.
(cherry picked from commit cf0bd2f73bd65beab613865bba567d7787836888)

Summary|Host rpcgen is sort of |rpcgen should have an
|fundamentally broken for |option to control explicit
|cross-compilers |CPP program
--- Comment #11 from Mike Frysinger <vapier at gentoo dot org> ---
what if we changed -Y behavior:
- stat the input arg
- if it's a dir, append "/cpp" automatically like we do today
- if it's a file, use the value unmodified
- throw an error otherwise
- update or delete find_cpp logic
there is the question of how do we pass down CPPFLAGS. we could add an
explicit flag like -y, or we could further extend the -Y behavior so that,
instead of throwing an error, we split on whitespace.

Bug ID: 21205
Summary: rpcgen chokes on #define lines
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: vapier at gentoo dot org
CC: carlos at redhat dot com
Target Milestone: ---
depending on the build settings, the preprocessor might emit #define lines
which causes rpcgen to choke
for example, with gcc-5.4, -ggdb3 will include #define lines:
$ CPP='gcc -ggdb3 -E -x c-header' rpcgen -Y ../scripts/ -h rpcsvc/rex.x -o foo
#define __STDC__ 1
rpcsvc/rex.x, line 1: preprocessor error
this can come up if the user tries to put -ggdb3 into their CFLAGS.

Bug ID: 21207
Summary: ce_RU: update weekdays from CLDR
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: digitalfreak at lingonborough dot com
CC: libc-locales at sourceware dot org
Target Milestone: ---
glibc locale shows:
$ LC_TIME=ce_RU.utf8 locale -ck LC_TIME
LC_TIME
abday="КI;Ор;Ши ;Кх ;Еа ;ПI ;Шо"
day="КIиранде ;Оршотде ;Шинариде ;Кхаариде ;Еариде ;ПIераÑкаде;Шотде"
...
while CLDR [1] says they should be:
кӀиранан де; оршотан де; шинарин де; ...
The Chechen locale data in glibc use a Latin uppercase letter "I" (Unicode:
U0049) while they should use a Cyrillic "Ó€" ("Palochka") which looks the same
but has Unicode encoding U04C0. [2]
Besides that, some of them have trailing spaces without any clear reason which
is a part of bug 20275.

--- Comment #1 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
Created attachment 9864
--> https://sourceware.org/bugzilla/attachment.cgi?id=9864&action=edit
Proposed solution
This patch updates weekday names and abbreviated weekday names from CLDR.
However, it does not switch the initial letters to lowercase although CLDR
suggests that. I guess the original author had some reason behind making these
letters uppercase. For example, maybe the weekday names are
usually/often/always displayed in the beginning of a sentence or standalone and
they look better starting with uppercase even if otherwise lowercase would be
used.
For easier reading, here is a decoded version explaining what the patch
actually says:

Another reproducer:
echo -en "\x0e\x0e" | /usr/bin/iconv -c -f IBM1364
We received an independent report of this issue, and I think we should treat
this as a minor security bug.

Bug ID: 21209
Summary: LD_HWCAP_MASK read in setuid binaries
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: siddhesh at sourceware dot org
Target Milestone: ---
To be on the safe side, LD_HWCAP_MASK should not be read in setuid binaries
since it may alter the variants of string and math functions that are used in
certain architectures, potentially increasing attack vector if an outdated
string implementation for an architecture is found to have an exploitable bug
that would have otherwise not affected newer platforms.
Patch coming up.

I'm flagging this as security- because we currently have no demonstrated

Bug ID: 21210
Summary: Wide-orientated stdout to file does many write(2)s of
length 16
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: ralph at inputplus dot co.uk
Target Milestone: ---
A program that does nothing by call putwchar(3) twenty times and exit results
in two write(2)s when run with stdout not to a TTY. First is length 16, second
it length 4.
col(1) from bsdmainutils and util-linux effectively does this. man(1) passes
larges amount of data through col, e.g. for zshall(1), and col passes it all
on, sixteen slow bytes at a time. Here's a line count of strace output for the
processes man kicks off.
2693 1000.man
735 1008.man-preconv
724 1009.man-tbl
76 1010.man-nroff
83038 1011.man-col All those write(2)s.
53 1013.man-nroff-locale
74 1016.man-nroff-groff
2519 1018.man-nroff-groff-troff
2353 1019.man-nroff-groff-grotty
Using setbuf(3) to declare stdout unbuffered results in write()s of length one,
as expected.  setbuffer(3) to give an explicitly large, 32KiB buffer still
results in tiny 16-byte writes.
On a byte-orientated stdout to a non-TTY, writes of 8KiB are seen, as expected.
Behaviour doesn't change between LC_ALL values of C and en_GB.utf8.

putwchar.c
Running putwchar.c under `strace -e write a.out' will show two write(2)s, first
with length 16.

--- Comment #3 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
Created attachment 9867
--> https://sourceware.org/bugzilla/attachment.cgi?id=9867&action=edit
Proposed solution
This patch should fix a problem for several languages. Some grep commands
revealed many trailing spaces. I have decided not to remove all of them. I
have left unchanged:
- those which clearly look like an attempt to align length of all items from
one group;
- int_curr_symbol: always has a trailing space so I guess there is a reason
behind it, also the recent commit comment which fixes these data says they
should have a trailing space;
- Arabic scripts: due to their RTL nature and due to my lack of knowledge I
can't be sure that a trailing space is really a trailing space.
I have removed those trailing spaces which appear at the end of all items from
a group or one or few random items without any clear reason.
Many of these locales use the scripts which I can't read so again I'd like to
hear some feedback from native speakers.
For easier understanding of what the patch does, here is its decoded version:

--- Comment #7 from Michael Matz <matz at suse dot de> ---
Just one more data point, we got a customer also being surprised by this
divergence from shell behaviour when all existing documentation suggests
that it should match. So, to get all info in one place, the redhat report
was:
https://bugzilla.redhat.com/show_bug.cgi?id=126460
our (https://bugzilla.novell.com/show_bug.cgi?id=1026911) is unfortunately
inaccessible to the outside, but describes exactly this issue with essentially
the same testcases.

Created attachment 9875

attempt to fix CVE-2016-10228
This is my attempt to fix that bug by advancing the buffer whenever an illegal
character is detected by one byte. While this does fix the specific examples in
this bug report I am not sure whether it is a good idea since I am not
particularly deep in that code.
Concerns that come to my mind and should be commented upon by someone that is
more familiar with that code:
1. Is the place I fixed here the only place that needs fixing or did I probably
miss other places.
2. Is advancing by one byte generally a good idea? Some character sets operate
on multiple byte characters. Do we need to consider this here and probably
advance with the character size instead? Is there information available in some
data structure about how many bytes we would need to advance?

>2. Is advancing by one byte generally a good idea?
In case where each codepoint is known to be encoded as the same number of
bytes, e.g. 4 octets in UTF-32, I would expect it to advance by that stride.

Exactly such a case I had in mind with my concern. Thus next task is to find a
way to determine within that context the size of each code point in bytes. This
might probably be a bit difficult given that this knowledge seems to be totally
encapsulated within the iconv function call.

Bug ID: 21229
Summary: strftime race conditions related to data filled by
tzset
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: time
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
strftime calls tzset and then accesses __tzname and calls mktime. These
accesses do not happen under the lock which protects the global timezone
variables, so there is a data race and strftime could use unexpected timezone
data.
It is unclear if POSIX actually requires that strftime calls tzset. POSIX
says, “Local timezone information is used as though strftime() called tzset().â€
If the intent is that strftime has the same side effect as calling tzset
directly, updating the tzname, daylight, timezone variables, this is a curious
way of putting it, although the same language is used for localtime.
Furthermore, with our current tzset implementation, a call to tzset means that
we have to access the file system on every call, to check if the timezone data
file hasn't changed (if such a file is used).

commit 1c1243b6fc33c029488add276e56570a07803bfd
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Tue Mar 7 20:52:04 2017 +0530
Ignore and remove LD_HWCAP_MASK for AT_SECURE programs (bug #21209)
The LD_HWCAP_MASK environment variable may alter the selection of
function variants for some architectures. For AT_SECURE process it
means that if an outdated routine has a bug that would otherwise not
affect newer platforms by default, LD_HWCAP_MASK will allow that bug
to be exploited.
To be on the safe side, ignore and disable LD_HWCAP_MASK for setuid
binaries.
[BZ #21209]
* elf/rtld.c (process_envvars): Ignore LD_HWCAP_MASK for
AT_SECURE processes.
* sysdeps/generic/unsecvars.h: Add LD_HWCAP_MASK.
* elf/tst-env-setuid.c (test_parent): Test LD_HWCAP_MASK.
(test_child): Likewise.
* elf/Makefile (tst-env-setuid-ENV): Add LD_HWCAP_MASK.

Created attachment 9882
--> https://sourceware.org/bugzilla/attachment.cgi?id=9882&action=edit
Part 1 ver. 2: be_BY, br_FR, es_PE, es_UY, fil_PH, fur_IT, fy_NL, ha_NG, ig_NG,
kw_GB, lg_UG, mg_MG, se_NO, sr_RS@latin, uz_UZ, uz_UZ@cyrillic, wae_CH
I've decided to move ln_CD to the second part because I suspect it may be
incorrect - see bug 12676 comment 13.

Part 2: ln_CD, mn_MN, vi_VN, yo_NG, zu_ZA
I suspect this patch may be incorrect but this suspect may be wrong. So I
publish it to let other people review. As always, it should be reviewed by the
people who at least roughly understand those languages.
For easier understanding here is a decoded version:

Summary: miss posix_fadvise64 on MIPS64 when static linking
Product: glibc

patch to fix the bug
Hi all，
I found the latest glibc do not provide posix_fadvise64 when static
linking.
It's very easy to reproduce the bug.
Compile the following code using "-static -D_FILE_OFFSET_BITS=64 -mabi=64",
ld will report " undefined reference to `posix_fadvise64'".
#include <fcntl.h>
int main()
{
posix_fadvise(0,0,0,0);
return 0;
}
The fix is quite simple as well, just two new lines in
sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise64.c. see the attached
file for details.

Thanks for your quick reply. All things should be discussed in the
mailing-list, I know the rules :)
My mail system currently can not send mails to
libc-alpha@sourceware.org(probably because of MIME content, But the system can
not send raw text now). I have tried many times, and got the same errors like
below.
I have reported this problem to our mail system developers, and I will send
corresponding mails to libc-alpha after they fix this problem.
==============================================================================
Hi. This is the qmail-send program at sourceware.org.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

Hi there,
Sorry if this is a duplicate.
I was trying to build glibc with CC set to '/usr/bin/gcc', CFLAGS set as
'-march=native' and --disable-sanity-check (since I'd like it to be installed
to /usr/local). It fails nearly immediately, saying that glibc cannot be
compiled without optimization.
Later, I attempt to try with CC set directly as '-march=native -O2' (It seems
that CFLAGS is sorted), and it compiles until vprintf.c, complaining:
In file included from ../bits/libc-header-start.h:33:0,
from ../libio/stdio.h:28,
from ../include/stdio.h:5,
from vprintf.c:20:
../include/features.h:373:4: error: #warning _FORTIFY_SOURCE requires compiling
with optimization (-O) [-Werror=cpp]
# warning _FORTIFY_SOURCE requires compiling with optimization (-O)
And I have seen explicit two -O2 from
/usr/bin/gcc -march=native -O2 vprintf.c -c -std=gnu11 -fgnu89-inline -O2
-Wall -Werror -Wundef -Wwrite-strings -fmerge-all-constants
-fno-stack-protector -frounding-math -fstack-protector-strong -march=x86-64
-mtune=generic -pipe -Wstrict-prototypes -Wold-style-definition -fexceptions
-ftls-model=initial-exec -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -I../include
(MUCH MORE...)
The preprocessor seems fail to detect optimization.

Target Milestone: ---
In code compiled with the Intel Fortran compiler
(ifort-v11 (IFORT) 16.0.3 20160415) with optimizing, my very old code suddenly
started misbehaving, giving NaNs unexpectedly. I traced this to when Debian
made the upgrade of libc6 from 2.24-8 --> 2.24-9. I then did some sleuthing to
discover that git commit fb0f7a6755c1bfaec38f490fbfcaa39a66ee3604 was the
culprit. Reversing this patch allowed things to work (as this binary does on
many, many different versions of glibc).
Rather than make a fix myself (I an not qualified), I can describe the
behavior: the problem seems to only occur on machines with an avx cpu flag. On
machines which list no AVX cpu flags, the bad behavior does not occur.
Unfortunately, I have been unable to run this on a machine with AVX512
instructions.

Bug ID: 21237
Summary: getaddrinfo doesn't cache list of network interfaces
if disabled ipv6
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: avkhozov at gmail dot com
Target Milestone: ---
Tested on 2.24-3ubuntu2 (ubuntu 16.10) and 2.19-18+deb8u7 (debian 8) systems.
getaddrinfo() doesn't cache list of network interfaces (we can see 3
getaddrinfo calls and 3 netlink requests) if ipv6 enabled and nscd turned off.
It's OK:
$ ip addr | grep inet6
inet6 ::1/128 scope host
inet6 fe80::e269:95ff:fe99:a961/64 scope link
$ sudo systemctl stop nscd
$ strace perl -MSocket=getaddrinfo -le 'getaddrinfo("google.ru", 0, {}) for
1..3' 2>&1 | grep -i netlink_route
socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE) = 3
socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE) = 3
socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE) = 3
$
Next, start nscd. getaddrinfo() start cache list of network interfaces (we can
see only one netlink request). It's OK:
$ sudo systemctl start nscd
$ strace perl -MSocket=getaddrinfo -le 'getaddrinfo("google.ru", 0, {}) for
1..3' 2>&1 | grep -i netlink_route
socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE) = 3
$
Next, disable ipv6. Cache does't work:
$ sudo sysctl net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.all.disable_ipv6 = 1
$ ip addr | grep inet6
$ strace perl -MSocket=getaddrinfo -le 'getaddrinfo("google.ru", 0, {}) for
1..3' 2>&1 | grep -i netlink_route
socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE) = 3
socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE) = 3
socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE) = 3
$
On systems with large number of interfaces it significantly affects the
performance when resolving names.

--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
Can you reproduce this with current upstream master? Instructions for running
a program against the newly built glibc are here:
https://sourceware.org/glibc/wiki/Testing/Builds#Compile_normally.2C_run_under_new_glibc
I suggest you engage Intel support. Without access to your binary, we cannot
tell if this is an Intel compiler issue, or a problem with the dynamic linker
trampoline. The trampoline is not obviously wrong.

Created attachment 9887
--> https://sourceware.org/bugzilla/attachment.cgi?id=9887&action=edit
Part 3: ar_DZ, ar_IQ, ar_JO, ar_LB, ar_MA, ar_SA, ar_SY, ar_TN, ks_IN, ps_AF,
ug_CN, ur_IN, ur_PK
The following patches may be wrong, incomplete, etc. because I can't read the
scripts they use, also because they are the results of import mon data only, so
for example abmon may also need an update. But I attach them here because
somebody may find them useful and needing only minor corrections. Reviewers
please check if other parts of locale data need update, too.
In case of ar_SY my patch conforms with the fix for bug 17225 at least in its
mon part (abmon is missing) at least partially seems to be correct.

Unfortunately, there is tons of internal global state in the current
implementation which is quite difficult to eliminate.
I looked at this in quite some detail and wrote down my observations here:

be_BY part seems correct. Consider also changing be_BY@latin. (it should be
"Maj" for both short and long forms.)

--- Comment #2 from Charles Schwieters <charles at schwieters dot org> ---
I have reproduced the behavior with the upstream master, including fixing
things by reverting that single commit. Thanks to the good documentation you
pointed me to, I was able to run this on more platforms, including a Xeon Phi
7230. Here is a summary of the results:
platform NaN occurs
Xeon Phi 7230 no
Xeon CPU E5-2670 yes
Xeon E5-1650 v2 yes
Pentium 4405 no
AMD Opteron 2218 no
My binary is available for this sort of analysis, but Intel may be the correct
place to turn.

--- Comment #9 from Dave Gotwisner <dgotwisn at netscout dot com> ---
Florian, from the bug description (and reading the manual page and code),
localtime_r specifically bypasses all the timezone database stuff. From the
manual page, localtim_r() ... stores the data in a user-supplied struct. It
need not set tzname, timezone, and daylight. Later, it indicates the _r
routines are thread safe.
Also, later in the NOTES section, "According to POSIX.1-2004, localtime() is
required to behave as though tzset() was called, while localtime_r() does not
have this requirement. For portable code tzset() should be called before
localtime_r(). Working off CentOS 6.5, manual page dated 2009-03-15 for
ctime(3).
From the code (see my earlier comment, but pasted here again):
/* Update internal database according to current TZ setting.
POSIX.1 8.3.7.2 says that localtime_r is not required to set tzname.
This is a good idea since this allows at least a bit more parallelism.
*/
If you look at my comment, I clearly give a path for code change that allows us
to meet this requirement without actually using any locks or additional TLS
variables (as walking through the code in localtime_r() mode, none of the
variables that must be protected are actually touched, except in [rare] error
conditions.
Your associated wiki page describes the behavior for all but localtime_r(), as
that interface doesn't read the timezone file, etc. It may go through the same
routines, but, because of parameters passed in, they go through the "safe"
paths.
The lock should be moved internal to code that actually needs it, not to the
outer code that doesn't (in this case). It might be reasonable to do some code
duplication to simplify the issue (a path for localtime_r(), a path for
everything else).

Address Sanitizer has been adjusted, so no further glibc changes are required.

This is an indirect consequence of bug 15686 and perhaps bug 16133.
All TLS access needs to be async-signal-safe, which is incompatible with
locking, and may require separate fixes, so leaving this bug open.

Any movement on this? It is now more than two months without
the hppa port being buildable at all.

--- Comment #5 from Henrique <hdante at gmail dot com> ---
Hello, I can confirm that this bug is still present. IPv6 link local addresses
(fe80::/64) only work when coupled with sockaddr_in6.sin6_scope_id (some
interface number). Since gethostent only returns the address (through
hostent.h_addr_list), then all IPv6 link local addresses are returned in an
incomplete way and so are broken.
This is why mdns does not work in linux with link local addresses.
Comparing with MacOS, getaddrinfo() seems to be implemented by the nss plugin,
so executing ssh -6 host.local works. In linux, executing ssh -6 host.local
does not work.

Bug ID: 21242
Summary: assert gives pedantic warning in old gcc versions
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jzb0012 at auburn dot edu
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 9892
--> https://sourceware.org/bugzilla/attachment.cgi?id=9892&action=edit
patch
The braced-group version of the assert macro introduced in commit e077349ce589
causes a warning in old versions of `gcc -pedantic` (without -ansi). This
warning also occurs in the latest clang. Patch attached.
main.c:
#include <assert.h>
int main() { assert(1); }
Without patched assert.h:
$ gcc-4.8 -pedantic main.c
$ gcc-4.4 -pedantic main.c
main.c: In function ‘main’:
main.c:2: warning: ISO C forbids braced-groups within expressions

We need to redesign the NSS interface anyway, but I'd prefer if we had the NSS
modules allocate the required memory, after bug 19591 is fixed.

100 while (temp_name_list != NULL)

110 }
111
We don't check the results of remove() and it could have failed. We should
check the result and issue a warning or fail depending on the situation.

In support/resolv_test.c (resolv_test_start)
1026 if (config.servers[server_index].disable_udp)
1027 {
1028 close (server->socket_udp);
1029 server->socket_udp = -1;
1030 }
1031 else if (!config.single_thread_udp)
1032 server->thread_udp = start_server_thread (obj, server_index,
1033 server_thread_udp);
1034 if (config.servers[server_index].disable_tcp)
1035 {

1038 }
1039 else
1040 server->thread_tcp = start_server_thread (obj, server_index,
1041 server_thread_tcp);
We should check the results of close() to be thorough.
In theory we are setting socket_udp/socket_tcp to -1 which is an invalid handle
to pass to close(), but on Linux it returns EBADF and you'd expect it to return
EBADF on any sensible implementation. We should check for this though and issue
an appropriate warning showing that an already closed handle was closed again.

When building upstream support/ infrastructure code in RHEL7 I see the
following warning:
In function 'resolv_response_add_name':
resolv_test.c:140:1: warning: inlining failed in call to
'response_add_byte.part.0': call is unlikely and code size would grow

response_add_byte (struct resolv_response_builder *b, unsigned char ch)

cc1: warning: called from here [-Winline]
in RHEL 7 the compiler, gcc version 4.8.5 20150623 (Red Hat 4.8.5-11), refuses
to inline response_add_byte.
The function response_add_byte is the only function marked 'inline'. Should we
remove the 'inline' markup or make this 'always_inline' (ignoring size growth).

How does this happen? We don't close the sockets if disable_udp or disable_tcp
are set.

I think this happens if the atexit handler runs in the child and in the parent.
I don't think we should warn for that.

commit ae65d4f3c3995279ca458c460ebf8bab1885fa03
Author: Wilco Dijkstra <wdijkstr@arm.com>
Date: Mon Mar 13 18:42:35 2017 +0000
Remove the str(n)dup inlines from string/bits/string2.h. Although
inlining
calls with constant strings shows a small (~10%) performance gain, strdup
is
typically used in error reporting code, so not performance critical.
Remove the now unused __need_malloc_and_calloc related defines from
stdlib.h.
Rename existing uses of str(n)dup to __str(n)dup so it no longer needs to
be
redirected to a builtin. Also building GLIBC with -Os now no longer shows
localplt or linkname space failures (partial fix for BZ #15105 and BZ
#19463).

--- Comment #3 from infinity0 at pwned dot gg ---
The point of this ticket is not about the *possibility* of doing this, but
about reducing the *cost* of doing this across the whole software ecosystem.
If glibc sets this as a default option, this would greatly reduce the cost of
doing this for everyone, down to zero.
If glibc hides this behind a -D_FORTIFY_SOURCE flag, OS distributions can
experiment with setting this globally, instead of every single project or user
doing it. Or, projects that prefer to distribute their own binaries can also
experiment with this flag themselves. Globally, the total sum cost of everyone
doing this is greatly reduced.
It's 2017 - more secure settings should be the default. I have been told about
some special cases when this might be a significant performance issue, but
these special cases (who already need to think about malloc specifics) should
be the ones having to set non-default more-risky mallopt options.
Furthermore, _FORTIFY_SOURCE has historically been a good mechanism for
distributions to improve the security of *all* of their programs, and it seems
a good fit for this issue as well. If every user or program writer had to set
an envvar or program option, instead of _FORTIFY_SOURCE being set automatically
on a whole-distribution level by Red Hat, Debian, and other distros, then
nearly nobody would be doing it even if "it's possible".

I'd be happy with a comment then about why we can't check the result of
remove() then, that way if the condition is ever lifted we can check the result
of the remove().

My apologies, I have not audited enough of the code to see if this is logically
possible, I just note that server->socket_tcp is both passed to close() and set
to -1 at some point.
My intent with this bug is to document that we should be checking the result of
close(), particularly if we're going to rely on a properly closed socket for
some future operation.

Yes, I have a build mostly fixed, the problem is we ran out of space in
pthread_cond_t to implement the new algorithm _and_ support old-style
Linuxthreads initializers.
So I guess a good question for you and Dave is:
* Should we stop supporting compat with old style static linuxthreads
initializers?
* Should we continue to support compat old style static linuxthreads
initializers, stealing 1-bit from the group size structure in the new algorithm
which would have a barely noticeable extra load on overflow.
Thoughts?

I don't see any compelling reason to do so.
I think it would be preferable to minimize the amount of code
specific to hppa. That, in the long run, is more helpful for
keeping minor platforms running.
As David has said, LinuxThreads has been gone for at least a decade.
I don't find it credible that there are binaries in any distribution
that haven't been recompiled since then.

Given that Dave has already weighed in on the topic by posting a patch to kill
the compat code I'll install that on Thursday unless someone beats me to it.

Changing the gcc compiler version to 6.2 the problem resolves.
So I guess it's a gcc problem and not a glibc problem.
So I am closing this as RESOLVED - INVALID

We support building glibc with GCC 4.7 or newer, therefore this is still a
valid bug and should get fixed.
However, if you don't care then we don't care because these issues with
compiler warnings are only relevant for the compilers that people are really
using.
Moving to GCC 6.2 is a good choice.

--- Comment #9 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Indeed the subtraction is at wrong place and for this specific case we case use
LEA (since it won't set CF flag use in following jbe). I think following the
logic already in place for x86_64 version is the correct approach:

If the sub is negative (as for the testcase since size is 1), sub will set CF
flag after the saturated addition and then return NULL as expected. I will
prepare the patch with the testcase as well.

Thanks a lot for your comment.
I haven't changed gcc. I just tested the newer gcc version and I saw that the
problem resolved.
That's why I guessed that the problem was with gcc and not glibc source code
and I closed the issue here.
So since my guess was wrong and this is a real bug I reopen the issue.
Thanks a lot in advance,
Tamis

You need to get such processor vendors to contribute support to upstream glibc,
or contribute the support yourself by refactoring the code to be able to run
the same CPU checks for different processors.
Set to WAITING for interested parties to contribute new support.

H.J.,
This looks like a serious issue with the dynamic loader support code that
saves/restores the AVX-related registers.
Do you have time to look into this?

The global, POSIX-specified variables aren't the problem if we only write to
them for use by application code (but not for internal use). We currently read
from __tzname in a few places, and these would have to be adjusted to use some
other way to obtain this information.
The larger problem is that we know only fairly late in the localtime_r
processing that we need to update global state beyond the POSIX variables, e.g.
when we call back from tzfile.c into tzset.c to compute future timezone
transitions based on a specified POSIX rule string.

Correct. This patch gets rid of the bad behavior:

According to x86-64 psABI, xmm0-xmm7 can be used to pass function
parameters. But ICC also uses xmm8-xmm15 to pass function parameters
which violates x86-64 psABI. As a workaround, you can set environment
variable LD_BIND_NOW=1 by
# export LD_BIND_NOW=1

Yes. LD_BIND_NOW=1 fixes things up. Is this a bug in icc/ifort/icpc which
should be fixed? I have a bug report open on the compilers. What are the
performance implications for LD_BIND_NOW=1? Thanks.

Given that this used to work do we need to carry a fix in glibc for ICC
binaries?
Or are you going to take this to the ICC team? Is this fixed in a particular
version of ICC?

There is nothing to fix in glibc since it follows x86-64 psABI.
I am discussing with ICC team now to see how to address this.

The strong alias adds linkspace issues showed by conform testcases (since
posix_fadvise64 is a glibc name convention). My understanding is it correct
approach is to use a weak_alias instead (as previous implementation). I will
prepare and send a patch.

Hi,
Thanks for your reply. I agree with your suggestion. And , your message
remind me to rethink about these weak_lias things carefully. I have rechecked
some functions similar to posix_fadvise64. Unfortunately, I still can not find
a very clear rule for there things. In my opinion, all open functional
interfaces in libc.a should be weak. Of course,this is not true for current
glibc. In fact, some functions in posix-standard are still strong symbols(for
example, fstatat). So, What is the right rule?

--- Comment #7 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
My understanding is all names reserved for standard conformance (POSIX, C,
etc.) are exported as strong alias since they are not expected to be
overridden. All implementation defined (such as posix_fadvise64) or extension
(for instance memrchr) are exported as weak symbols, so a program which does
not want to actually use its extension can provided its own if required.

commit e4e52ff059f46472145433d2bd003d5383f89e82
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Mar 15 22:00:54 2017 +0000
Improve float range reduction accuracy near pi/2 (bug 21094).
Bug 21094 reports 3ulp errors of cosf and tanf for certain arguments
near pi/2 arising from the use of an insufficiently accurate range
reduction. (To be clear, this is a quality-of-implementation issue
relating to the apparent intent of those particular cosf and tanf
implementations; 3ulp is within the general glibc accuracy goals, so
not inherently a bug.)
This patch fixes that error by making a wider range of cases use the
existing more accurate range reduction for arguments close to pi/2.
The wider range of values is still narrow enough for the "z -=
pio2_2;" in the more accurate case to be exact, as the code expects.
Tested for x86_64, x86 and mips64; no ulps updates needed (but at
least on mips64, the larger ulps were seen if the tests were added
without the substantive fix).
[BZ #21094]
* sysdeps/ieee754/flt-32/e_rem_pio2f.c (__ieee754_rem_pio2f): Use
24+24+24-bit pi for wider range of values around pi/2.
* math/auto-libm-test-in: Add more tests of cos and tan.
* math/auto-libm-test-out-cos: Regenerated.
* math/auto-libm-test-out-tan: Likewise.

Fix getting tunable values on big-endian (BZ #21109)
The code to set value passed a tunable_val_t, which when cast to
int32_t on big-endian gives the wrong value. Instead, use
tunable_val_t.numval instead, which can then be safely cast into
int32_t.

sunrpc: Improvements for UDP client timeout handling [BZ #20257]
This commit fixes various aspects in the UDP client timeout handling.
Timeouts are now applied in a more consistent fashion. Discarded UDP
packets no longer prevent the timeout from happening at all.

sunrpc: Avoid use-after-free read access in clntudp_call [BZ #21115]
After commit bc779a1a5b3035133024b21e2f339fe4219fb11c
(CVE-2016-4429: sunrpc: Do not use alloca in clntudp_call
[BZ #20112]), ancillary data is stored on the heap,
but it is accessed after it has been freed.
The test case must be run under a heap debugger such as valgrind
to observe the invalid access. A malloc implementation which
immediately calls munmap on free would catch this bug as well.

Bug ID: 21253
Summary: localedef randomly segfaults when using -fstack-check
due to new posix_spawn implementation
Product: glibc
Version: 2.24
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: vapier at gentoo dot org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
looks like the new posix spawn logic creates too small of a stack in some
cases. building glibc-2.24 w/gcc-4.9 and PIE+SSP+stack-check leads to random
segfaults.
example:
$ gdb --args localedef -c -i bg_BG -f UTF-8 bg_BG.UTF-8
Reading symbols from localedef...Reading symbols from
/usr/lib/debug//usr/bin/localedef.debug...done.
done.
(gdb) set follow-fork-mode child
(gdb) run
Starting program: /usr/bin/localedef -c -i bg_BG -f UTF-8 bg_BG.UTF-8
[New process 1209]
Thread 2.1 "localedef" received signal SIGSEGV, Segmentation fault.
[Switching to process 1209]
0x00007ffff7b178ec in __spawni_child (arguments=0x7fffffffdb30) at
../sysdeps/unix/sysv/linux/spawni.c:120
120 {
(gdb) bt
#0 0x00007ffff7b178ec in __spawni_child (arguments=0x7fffffffdb30) at

#1 0x00007ffff7b2676f in clone () at
../sysdeps/unix/sysv/linux/x86_64/clone.S:105
(gdb)
increasing the stack size in __spawnix helps, but going by the gcc internal
docs, it sounds like it'd be pretty painful to try and find a good value all
the time for all targets.
https://gcc.gnu.org/onlinedocs/gcc-6.3.0/gccint/Stack-Checking.html
would be easier to just disable stack checking on this one file.

playing around, disabling -fstack-check on this one file doesn't help. we'd
have to disable it on every func __spawni_child calls too. at which point we
might as well disable it everywhere. blah.

--- Comment #7 from Robert Schiele <rschiele at gmail dot com> ---
Ok, I experimented quite a bit to figure out the minimal number of bytes used
to encode a code point but it seems I didn't really fully understand the
underlying data structure and so far didn't find a working solution for all
cases I tested.
Therefore for my own purposes I left the solution advancing one byte, leaving
the risk that for some encodings the output can contain even more garbage than
what was found in the input, following the concept "garbage in, garbage out".
At least it still avoids the tool to hang in those cases.
I leave it to the experts of this code area to improve this fix or provide me a
hint, where in the data structures I can find the information about what is the
smallest number of bytes for one code point in the input data encoding.

--- Comment #2 from Florian Weimer <fweimer at redhat dot com> ---
I don't think it makes sense to keep this bug open.
We don't know if other vendors use the exact same feature bits as Intel and
AMD. So checking the vendor name is safer. If we didn't do that and there's a
CPU out there which reinterprets feature bits, glibc might not work at all.

Summary: Branch predication in _dl_runtime_resolve_avx512_opt
leads to lower CPU frequency
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
Target: x86-64
On Skylake server, _dl_runtime_resolve_avx512_opt is used to preserve
the first 8 vector registers. The code layout is
if only %xmm0 - %xmm7 registers are used
preserve %xmm0 - %xmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %zmm0 - %zmm7 registers
Branch predication always executes the fallthrough code path to preserve
%zmm0 - %zmm7 registers speculatively, even though only %xmm0 - %xmm7
registers are used. This leads to lower CPU frequency.

sysdeps/unix/sysv/linux/alpha/bits/termios.h defines IXANY only if __USE_MISC.
But it's in the base standard for POSIX.1:2008, and XSI-shaded in previous
standards. This omission results in:

conformtest: Add alpha XFAIL for struct netent n_net type (bug 21260).
As noted in bug 21260, sysdeps/unix/sysv/linux/alpha/bits/netdb.h
defines struct netent with n_net of type unsigned long instead of the
correct uint32_t. This patch XFAILs that test in the conformtest
expectations for alpha. (This is not a fix for the bug, and it should
not be closed without an actual fix.)
Tested for alpha with build-many-glibcs.py.
[BZ #21260]
* sysdeps/unix/sysv/linux/alpha/Makefile
[$(subdir) = conform] (conformtest-xfail-conds): New variable.

commit 0cb521871ba11772fb52617cdba1b66089ffd749
Author: Joseph Myers <joseph@codesourcery.com>
Date: Fri Mar 17 02:54:59 2017 +0000
conformtest: Add mips XFAIL for struct stat st_dev type (bug 17786).
As noted in bug 17786, MIPS o32 struct stat has the wrong type of
st_dev. This patch XFAILs that test in the conformtest expectations
for this case (the test still fails after the patch because there's
also a similar issue for st_rdev that needs reporting and XFAILing
separately, and the bug should not be closed without an actual fix,
not just XFAILing).
Tested for mips with build-many-glibcs.py.
[BZ #17786]
* sysdeps/unix/sysv/linux/mips/mips32/Makefile: New file.
* conform/data/sys/stat.h-data (stat.st_dev): XFAIL for
mips-o32-linux.

Bug ID: 21264
Summary: Selective static linking of libm.a fails due to
unresolved _dl_x86_cpu_features symbol
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Target: x86_64
Example from the downstream bug report:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(int argc, char **argv)
{
printf("string:%s\n",argv[1]);
float input=strtof(argv[1],NULL);
printf("input:%f\n",input);
float result;
result = sin(input);
printf("%f\n",result);
return 0;
}
GCC command line (note that libm is linked statically, but libc is linked
dynamically):
gcc test.c -Wl,-Bstatic -lm -Wl,-Bdynamic -lc
Actual results:
Linker error message:
/usr/lib64/libm-2.25.90.a(s_sin.o): In function `__cos_ifunc':
(.text+0x4d22): undefined reference to `_dl_x86_cpu_features'
/usr/lib64/libm-2.25.90.a(s_sin.o): In function `__sin_ifunc':
(.text+0x4d52): undefined reference to `_dl_x86_cpu_features'
I'm not sure if it is reasonable for our users to expect this to work, but so
far we did not actively prevent that from happening.

Given that almost nobody uses the Intel C++ __regcall calling convention,
please don't slow down the dynamic linker for everyone else.

commit 20409ce5e806c7d2fba103d6b88b5a0c2f2fbf5a
Author: Joseph Myers <joseph@codesourcery.com>
Date: Fri Mar 17 16:27:03 2017 +0000
Make alpha termios.h define IXANY unconditionally (bug 21259).
sysdeps/unix/sysv/linux/alpha/bits/termios.h defines IXANY only if
__USE_MISC. But it's in the base standard for POSIX.1:2008, and
XSI-shaded in previous standards. This patch makes the header define
it unconditionally, like other versions of this header do (it's always
reserved by standards that don't require it, so defining
unconditionally is OK by the standards).
Tested (compilation only) for alpha with build-many-glibcs.py. Note
that there are still termios.h conformtest failures after this patch
because of other issues with the alpha version of this header.
[BZ #21259]
* sysdeps/unix/sysv/linux/alpha/bits/termios.h (IXANY): Define
unconditionally, not just for [__USE_MISC].

This would mix old / new libm.a with old / new libc.so.6 / ld.so and that's not
supported.
Either you link statically or you link dynamically. The entire runtime has to
come together to form the basis of the implementation.
The exceptions are things like NSS modules which have some special caveats
here.

The presence of libm.a is an implementation detail. We might reopen this issue
to discuss ways to prevent users from thinking it works to link against just
libc.a instead of using -static.

Like the regparm attribute on 32-bit x86 it can only be safely used by internal
function calls.

Summary: i386 sigaction sa_restorer handling is wrong
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc

Reporter: luto at kernel dot org

glibc does this:
if (GLRO(dl_sysinfo_dso) == NULL)
{
kact.sa_flags |= SA_RESTORER;
kact.sa_restorer = ((act->sa_flags & SA_SIGINFO)
? &restore_rt : &restore);
}
This is correct for the vDSO-present case, but it's subtly wrong for the
vDSO-not-present case. For ancient historical reasons, x86_32 Linux (and
compat on x86_64) interprets SA_RESTORER clear with nonzero sa_restorer as a
request for stack switching if the SS segment is funny. This means that
anything that tries to mix glibc's signal handling with segmentation is
randomly broken depending on what garbage lands in sa_restorer. (Also, it's
just bad form to pass uninitialized data into the kernel.)
The fix should be trivial:
else
kact.sa_restorer = NULL;
or similar.
I can send a short test case if needed.

Summary: mmap64 silently truncates large offset values
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: thiago at kde dot org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
sysdeps/unix/sysv/linux/mmap64.c:
INLINE_SYSCALL (mmap2, 6, addr,
len, prot, flags, fd,
(off_t) (offset >> page_shift));
If one calls mmap64 with an offset value larger than 1 << (page_shift +
8*sizeof(off_t)) [that is, 1<<44], the system call silently truncates the
offset. This aliasing with lower offsets could result in file corruption, as
same area of the file could be mapped twice, unbeknownst to the application.
Other implementations:
* the BSDs don't have mmap64: 32-bit mmap() takes 64-bit offsets
* OpenSolaris has mmap64 and that maps 1:1 with the 64-bit system call
* Bionic, uClibc, MUSL: all affected by the same issue
POSIX makes no provision for failing at mmap() if the offset is too large for
arbitary file descriptors. It says that the application should SIGBUS if access
is attempted. It does allow for EOVERFLOW for regular files:
[EOVERFLOW]
The file is a regular file and the value of off plus len exceeds the offset
maximum established in the open file description associated with fildes.
Other possible errors:
[ENXIO]
Addresses in the range [off,off+len) are invalid for the object specified
by fildes.
Or ENOTSUPP.
If needed to keep a success result, then mmap64 could emulate the behaviour by
mapping one page past the end of a different (empty) file, opened in read-only
mode. This generates SIGBUS for reads and should be correct also for memory
writes.

commit 19641dbd61fe0440fa1f0ebd2f358b5ba98e839f
Author: Joseph Myers <joseph@codesourcery.com>
Date: Sat Mar 18 00:17:25 2017 +0000
Fix sparc64 bits/setjmp.h namespace (bug 21261).
sysdeps/unix/sysv/linux/sparc/bits/setjmp.h defines 64-bit __jmp_buf
with a load of identifiers that are not part of any standard
namespace, resulting in conform/ tests failing. This patch fixes this
by moving those identifiers to the implementation namespace, so
enabling the conform/ tests to pass for sparc64.
Tested (compilation only) for sparc64 with build-many-glibcs.py.
[BZ #21261]
* sysdeps/unix/sysv/linux/sparc/bits/setjmp.h
[__WORDSIZE == 64 && !_ASM] (__sparc64_jmp_buf): Use reserved
names for all fields.
* sysdeps/sparc/sparc64/jmpbuf-unwind.h (_JMPBUF_UNWINDS): Update
for jmp_buf field renaming.
(_JMPBUF_UNWINDS_ADJ): Likewise.

conformtest: XFAIL tv_nsec tests for x32 (bug 16437).
This patch XFAILs the conformtest tv_nsec tests for x32 so that the
incorrect type does not potentially hide other failures. As this is
not a fix for the bug, it should remain open in Bugzilla.
Tested (compilation only) with build-many-glibcs.py.
[BZ #16437]
* sysdeps/unix/sysv/linux/x86_64/x32/Makefile
[$(subdir) = conform] (conformtest-xfail-conds): New variable.
* conform/data/signal.h-data (timespec.tv_nsec): XFAIL for
x86_64-x32-linux.
* conform/data/sys/select.h-data (timespec.tv_nsec): Likewise.
* conform/data/sys/stat.h-data (timespec.tv_nsec): Likewise.

Bug ID: 21273
Summary: insuffizient memory with more then 10 GB free memory
Product: glibc
Version: 2.22
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: dieter.ferdinand at gmx dot de
Target Milestone: ---
hello,
since my last systemupdate (gentoo-linux) and update to glibc 2.22-r4 i have
much problems with the memory-management and if i use some programs witch need
much memory (firefox, chromium, java) the programs begin to crash after some
time or if i open some more tabs or windows and every time i get a message
which says, that there are missing resources or memory.
if i close chromium or firefox, i can work again or i must close windows in one
or both browsers.
before i update the system, i can open much more tabs or windows in chrome
without proplems, after the update i must close over 50% of my open websites or
chrome/chromium crashs at startup.
i don't know, where i must search for this problems, but i think this is a
problem from glibc while the problem happens before i update the kernel.
i hope that you can help me.
i use a 32bit kernel 3.18.47 with 16GB ram and while i have this
memory-problems, i will try to update to a 64bit system, but will this solve my
problems ?
goodby

Bug ID: 21275
Summary: posix_spawn always crashes on ia64 now
Product: glibc
Version: 2.24
URL: https://bugs.gentoo.org/show_bug.cgi?id=613288
Status: NEW
Severity: normal
Priority: P2
Component: libc

CC: drepper.fsp at gmail dot com
Target Milestone: ---
Host: ia64-linux-gnu
the new posix spawn code passes the stack base incorrectly on ia64. this is
because the common clone() expects the initial stack value to be passed in
where as on ia64, it wants the base of the stack mapping on its total size.

--- Comment #83 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
Created attachment 9908
--> https://sourceware.org/bugzilla/attachment.cgi?id=9908&action=edit
Proposed solution: support alternative month names (version 6)
Here is the new set of patches.
Differences between the patch from comment 70 and this one:
- alt_mon section in locale data source made optional again, like in comment
the data will be generated while compiling to binary;
- comments reworded not to suggest that alt_mon is standalone (nominative) and
mon is for formatting full date (genitive), this will be decided later;
- ALTMON_x macros defined only if __USE_GNU is defined; for now they are
treated as GNU-only extension.

Proposed solution: implement the %OB format specifier (v6)
Difference between the patch from comment 74: commit comment reworded not to
suggest that %OB is standalone (nominative) and %B is for full date format
(nominative), this will be decided later. Really no changes in the code.

--- Comment #89 from keld at keldix dot com <keld at keldix dot com> ---
Hi
I would ask that our changes are backwards compatible, so that we need not
change
the existing data, just addin new data, (and changing the date format spec).
Something like the %B is the nominative case, %OB is the genitive case, and
then
the full date spec is using %OB for the month names when required.
And the alt_mon is an optional keyword, and general. I believe these changes
are
getting their way into both POSIX and i18n 30112 standards.
Best regads
keld

Created attachment 9914

Let alternative month names be a copy of regular ones
This is a new patch: alt_mon section is optional in the locale data source file
but this patch modifies the compiler to generate the missing alt_mon section as
a copy of mon section in the binary output file.
The difference between the patch from comment 81 and this one is not obvious:
the old patch actually added alt_mon section to all source files while this one
makes them unnecessary and generates the missing data automatically.

Also implement abbreviated alternative month names and %Ob
This is a new patch. I realized that at least in case of May in Russian and
Belarusian also abbreviated month names may have nominative/genitive form, in
this particular case because the word is so short that its abbreviated form
equals the full form. A similar phenomenon may also exist in other languages
which I am not yet aware of. So this patch repeats all the above steps to
implement _NL_ABALTMON_x constants in nl_langinfo() and "%Ob" format specifier
in strftime(), except the backward compatibility.

Do you have a copyright assignment for glibc? If not, I'd prefer if you could
describe what we need to test instead, so that we can write our own test case.
(And yes, we'd very much like to have a test case for this.)

Please consult Gentoo support resources to help with isolating the root cause.
If it is indeed a glibc bug, you can file a new bug report with more

Attachment #9717|0 |1

--- Comment #93 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
Created attachment 9917
--> https://sourceware.org/bugzilla/attachment.cgi?id=9917&action=edit
Alternative month names NLS data (Russian, v6)
Differences between the patch from comment 78 and this one:
- Adds ab_alt_mon section (this is an example of how and why this feature can
be used).
- No longer changes the nominative cases to lowercase. CLDR suggests to use
the standalone/full-date-format feature to start standalone cases with
uppercase letter even for the languages which don't need always the uppercase
letter because a standalone word is an expression by itself (like a sentence).
I'm not sure if the Russian language community will like it, let them decide.
This is just an example, I don't suggest they will actually push it without
changes.

I think this is mainly for internal glibc use (see the internal_function
macro). I don't think you should read into this that glibc supports a
different ABI than what's specified in the psABI supplement.
What makes this bug different from bug 21236?

Created attachment 9918

Import genitive month names from CLDR (v6)
Differences between the patch from comment 82 and this one:
- only those languages which have and need the nominative/genitive case in
dates are imported here;
- this new patch does not assume that alt_mon section already exists (the patch
from comment 81 is obsoleted/rejected) so it adds these sections;
- be_BY: also adds ab_alt_mon section;
- wa_BE: adds a space after "d’" which I did not know was needed.

Import uppercase/lowercase month names from CLDR (v6)
Some languages which don't need the genitive/nominative difference already use
this feature in CLDR to start the month names with uppercase if they are
standalone and with lowercase when they are in full date context. This was
already imported previously in the comment 82, this patch splits out these
cases.

--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
Reproducer (more or less):
#include <stdlib.h>
#include <pthread.h>
void *p = &pthread_create;
int main(int argc, char **argv)
{
malloc (10);
return 0;
}
Compile without optimization and link with -static -lpthread.
I think the static TLS allocation is considered uninitialized by valgrind for
some reason. I do not know if valgrind is right here and the memory is
actually uninitialized, or if the kernel guarantees that it is
zero-initialized. Fresh memory returned by brk is generally zero-initialized,
but I don't know what happens if the brk pointer is decremented and incremented
again (say by parasite code in the process—nothing else can run so early during
process setup). Would that cause the kernel to clear the re-exposed memory
region?

--- Comment #96 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
Hi,
(In reply to keld@keldix.com from comment #89)
> Hi

> I would ask that our changes are backwards compatible, so that we need not

It's been discussed here and in the libc-alpha list. The current consensus is
that whether you decide that %B is nominative or %OB is genitive or the other
way round does not change the source code: the difference is only on input
(locale data) and output (format specifiers in applications). Both controlled
by language communities. So these changes are acceptable as long as they do
not suggest which is nominative and which is genitive and this will be decided
later. By later I mean later in this development cycle, not later in a distant
future.
Also I have some reasons why I suggest switching %B to genitive and introduce
%OB as nominative which I published many times before (links available).

Done in this series of patches.

POSIX has accepted (but not yet published) the opposite solution:
http://austingroupbugs.net/view.php?id=258. Regarding ISO 30112 I'm not aware
of their opinion about it. Can you please provide some more up to date info?
I have already prepared a copr repository for any modern Fedora so if you are
brave enough you can install it and test already how many applications are
fixed and how many are broken because of these changes. I'll be glad to hear
your feedback. The repo is at
https://copr.fedorainfracloud.org/coprs/rluzynski/genitive/

Bug ID: 21276
Summary: gettimeofday() segfaults when called before libc
init() and before calling _dl_vdso_vsym()
Product: glibc
Version: 2.22
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: Vinitha.Vijayann at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Hi,
While tracing pthread library, I am calling gettimeofday right after
__pthread_initialize_minimal() . This is before finishing libc init and when
the _dl_vdso_vsym() is not called yet to fixup __vdso_gettimeofday(). Because
of this __vdso_gettimeofday is NULL at this point.
This results in a SEGV in gettimeofday (Target is armv7 and vdso support is
enabled ).
I am not sure whether this is a bug in gettimeofday().
When checked the target specific gettimeofday implementation in case of x86,
found the following check
In sysdeps/unix/sysv/linux/x86/gettimeofday.c
34 void *
35 gettimeofday_ifunc (void)
36 {
37 PREPARE_VERSION_KNOWN (linux26, LINUX_2_6);
38
39 /* If the vDSO is not available we fall back to syscall. */
40 return (_dl_vdso_vsym ("__vdso_gettimeofday", &linux26)
41 ?: (void*) (&__gettimeofday_syscall));
42 }
Can we add the similar kind of checking in case of generic gettimeofday()
implementation also so that this SEGV does not occur.
int
__gettimeofday (struct timeval *tv, struct timezone *tz)
{
PREPARE_VERSION_KNOWN (linux26, LINUX_2_6);
/* If the vDSO is not available we fall back to syscall. */
if(_dl_vdso_vsym ("__vdso_gettimeofday", &linux26))
return INLINE_VSYSCALL (gettimeofday, 2, tv, tz);
else
{
INTERNAL_SYSCALL_DECL(err);
return INTERNAL_SYSCALL(gettimeofday,err,2, tv, tz);
}
}
Please advice.
Regards,
Vinitha

posix allows EINVAL if ".. off is not a multiple of the page size as returned
by sysconf(), or is considered invalid by the implementation".
so EINVAL is conforming too, silently truncating is not. (musl libc uses
EINVAL).

--- Comment #6 from Florian Weimer <fweimer at redhat dot com> ---
Note that there is a parallel mailing list thread reviewing this ABI change
proposal:
https://sourceware.org/ml/libc-alpha/2017-03/msg00343.html
I think we still need some ABI documentation even if more registers are
preserved because arbitrary calling conventions still will not work. Using
noplt calls as a workaround in the Intel compiler seems a reasonable fix (no
ABI changes required, but this still needs documentation in the psABI
supplement IMHO).

My high level opinion:
(a) "Optimize for the local special case": Use of regparm and __regcall is
restricted to internal functions. The goal is to optimize internal calls as
much as possible with the additional registers. The example of i386 support and
internal_function macro is a good example of optimizing internal function
calls.
(b) "Optimize for the global average case": Use of regparm and __regcall should
not be extended to support interposable global symbols. We should optimize for
the general case which doesn't use regparm/__regcall and which supports
developers interposing code using the standard x86_64 ABI.
If you want (a) to cover more of your program then you need to look at -fno-plt
(as Florian Weimer suggests) and LTO to make more of your program local and
enable the optimizations that allows.

posix_spawn: fix stack setup on ia64 [BZ #21275]
The ia64-specific clone2 call expects the base of the stack mapping and
the stack size as sep arguments, not an initial stack value as on other
stack-grows-down architectures. Reuse the stack-grows-up macro so we
pass in the right stack base.

posix_spawn: fix stack setup on ia64 [BZ #21275]
The ia64-specific clone2 call expects the base of the stack mapping and
the stack size as sep arguments, not an initial stack value as on other
stack-grows-down architectures. Reuse the stack-grows-up macro so we
pass in the right stack base.

I see crashes 100% of the time in tools/testing/selftests/x86/ldt_gdt_32 in
Linux (if run on SMP) on Fedora 25. I didn't before, presumably because of
luck.

No copyright assignment.
The most straightforward reproducer I can think of is to set up a struct
user_desc that's all zeros except entry_number = -1, limit = 0xfffff, seg_32bit
= 1, and limit_in_pages = 1. Call set_thread_area(2) on it. Set up a handler
for SIGTRAP -- details don't really matter.
Then do (intentionally not valid C so you can't copy it):
mov [(entry_number << 3) | 3], %ss

A successful test will run the signal handler. A failed test will segfault.
What's going on is that the combination of SA_RESTORER clear, sa_restorer != 0,
and nondefault %ss is interpreted as "change my stack pointer to the value in
sa_restorer". The result is a crash.
This obviously won't affect the vast majority of programs that use glibc
because, while the first two conditions will be met, the latter condition is
rather unlikely.

EINVAL would indeed be better.
You're also right, musl does check for invalid size. I had missed the
definition of the OFF_MASK that includes the bits for 1<<44 and higher. They
have a weird definition of it:
#define OFF_MASK ((-0x2000ULL << (8*sizeof(long)-1)) | (UNIT-1))
Instead of -0x2000ULL and shifting left by the number of bits in long minus
one, I'd have done -0x1000ULL (which is a page) and shift left by the number of
bits.

Okay, I'll try to turn this into an actual test case.
Any suggestions how to block the vDSO mapping? I assume that's needed as well
before the bug can trigger.

As far as I know, anything marked with internal_function should never be
called through the PLT. Are there any such functions that are not also
marked with attribute_hidden?

Apart from the functions I added because not knowing about this rule, there is
__libc_pthread_init, which is defined in libc.so.6 and called from
libpthread.so.0.

Let me know if you have issues and I can help with the test. My test here
seems to work as expected. Sigh, copyright assignment.

I got it backwards in my original report. The buggy path runs when the vDSO is
present and does not run when the vDSO is absent. IOW gcc -m32 testcase.c is
sufficient.

commit ba7fe6906d213e226dff8606dca64feb48718e27
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Mar 20 17:32:19 2017 +0000
Fix alpha termios.h NL2, NL3 namespace (bug 21268).
sysdeps/unix/sysv/linux/alpha/bits/termios.h defines NL2 and NL3 for
__USE_MISC || __USE_XOPEN. These should only be defined for
__USE_MISC as they are not part of any standard namespace. This patch
conditions them accordingly, matching the powerpc version of the
header (the only other one in glibc that defines these macros).
Tested (compilation only) with build-many-glibcs.py.
[BZ #21268]
* sysdeps/unix/sysv/linux/alpha/bits/termios.h (NL2): Define only
if [__USE_MISC]
(NL3): Likewise.

termios.h should define IUCLC for UNIX98 and older XSI standards. The
sysdeps/unix/sysv/linux/alpha version defines it only if __USE_MISC, so causing
some conform/ tests to fail.

--- Comment #2 from Vinitha Vijayan <Vinitha.Vijayann at gmail dot com> ---
I am tracing pthread library using Pthread Trace Tool
(http://nptltracetool.sourceforge.net/). The initialization of ptt tracing, is
done after pthread_initialization in the _init section. Here to get the
timestamp, gettimeofday() is called. HP-TIMING cannot be used here as ARM
doesn't support that.
For earlier version of glibc, this was working fine.
Since the vdso support was enabled for gettimeofday, this SEGV is observed.
To test the threaded application, ptt daemon forks the application and preloads
the pthread library( with trace points enabled).
So libpthread is getting initialized first.
Then the glibc init is called, after which the _dl_vdso_vsym() is called.
So gettimeofday() is called before the _dl_vdso_vsym() is called to fixup
__vdso_gettimeofday.
Hope this is clear :(

What ptt is doing is undefined. You cannot poke at such library internals and
expect things are going to work. One of the issues you might encounter could
still be fixed along with bug 21041, though.

commit 112039611cc21c5cbe41b578633f39d2fe396618
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Mar 20 21:28:16 2017 +0000
conformtest: Add mips XFAIL for struct stat st_rdev type (bug 21278).
MIPS o32 struct stat has the wrong type of st_rdev. This patch XFAILs
that test in the conformtest expectations for this case (the bug
should not be closed without an actual fix, however).
Tested with build-many-glibcs.py.
[BZ #21278]
* sysdeps/unix/sysv/linux/mips/mips32/Makefile
[$(subdir) = conform] (conformtest-xfail-conds): Update comment.
* conform/data/sys/stat.h-data (stat.st_rdev): XFAIL for
mips-o32-linux.

commit 76b2c32a166f4812c0649162c9df99d707779304
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Mar 20 21:30:28 2017 +0000
conformtest: Add x32 XFAILs for mq_attr element types (bug 21279).
POSIX specifies long as the type of elements of struct mq_attr. For
x32, they are __syscall_slong_t (i.e. long long). This patch XFAILs
the corresponding tests for x32 in the conformtest expectations (the
bug should not be closed without an actual fix).
Tested with build-many-glibcs.py.
[BZ #21279]
* sysdeps/unix/sysv/linux/x86_64/x32/Makefile
[$(subdir) = conform] (conformtest-xfail-conds): Update comment.
* conform/data/mqueue.h-data (mq_attr.mq_flags): XFAIL for
x86_64-x32-linux.
(mq_attr.mq_maxmsg): Likewise.
(mq_attr.mq_msgsize): Likewise.
(mq_attr.mq_curmsgs): Likewise.

x86-64: Improve branch predication in _dl_runtime_resolve_avx512_opt [BZ
#21258]
On Skylake server, _dl_runtime_resolve_avx512_opt is used to preserve
the first 8 vector registers. The code layout is
if only %xmm0 - %xmm7 registers are used
preserve %xmm0 - %xmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %zmm0 - %zmm7 registers
Branch predication always executes the fallthrough code path to preserve
%zmm0 - %zmm7 registers speculatively, even though only %xmm0 - %xmm7
registers are used. This leads to lower CPU frequency on Skylake
server. This patch changes the fallthrough code path to preserve
%xmm0 - %xmm7 registers instead:
if whole %zmm0 - %zmm7 registers are used
preserve %zmm0 - %zmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %xmm0 - %xmm7 registers
Tested on Skylake server.
[BZ #21258]
* sysdeps/x86_64/dl-trampoline.S (_dl_runtime_resolve_opt):
Define only if _dl_runtime_resolve is defined to
_dl_runtime_resolve_sse_vex.
* sysdeps/x86_64/dl-trampoline.h (_dl_runtime_resolve_opt):
Fallthrough to _dl_runtime_resolve_sse_vex.

--- Comment #4 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Currently we have 18 different mmap/mmap64 implementation for Linux on glibc,
so it would be nice to actually have a consolidate implementation to fix this
bug once (instead of replicating on multiple implementation). I will work on
the consolidation and also add this fix.

Summary: bits/siginfo.h is missing enum definition for
TRAP_HWBKPT
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org

Fix for the reported issue
Description of problem:
#wget
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/testing/selftests/breakpoints/breakpoint_test_arm64.c
# gcc -o breakpoint_test_arm64 breakpoint_test_arm64.c
breakpoint_test_arm64.c: In function ‘run_test’:
breakpoint_test_arm64.c:171:25: error: ‘TRAP_HWBKPT’ undeclared (first use in
this function)
if (siginfo.si_code != TRAP_HWBKPT) {
^
breakpoint_test_arm64.c:171:25: note: each undeclared identifier is reported
only once for each function it appears in
I compiled this file locally with following addition in my
/usr/include/bits/siginfo.h, and sorry I forgot to upstream changes to glibc :(
# diff /usr/include/bits/siginfo.h ~/siginfo.h
229c229
< TRAP_TRACE, /* Process trace trap. */
---
> TRAP_TRACE /* Process trace trap. */
231,234d230
< TRAP_BRANCH, /* Process branch trap. */
< # define TRAP_BRANCH TRAP_BRANCH
< TRAP_HWBKPT /* hardware breakpoint/watchpoint */
< # define TRAP_HWBKPT TRAP_HWBKPT
I think attached patch should resolve it in upstream glibc.

We are indeed missing several of the TRAP_* constants in the userspace
definitions. Specifically TRAP_BRANCH and TRAP_HWBKPT.

the following issue happens:

Investigation shows that for this configuration preprocessor generates line
int fts_set (FTS *, FTSENT *, int) __asm__ ("" "fts64_set") throw ();
which causes the error. But the line
int fts_set (FTS *, FTSENT *, int) throw () __asm__ ("" "fts64_set");
compiles successfully though and assembly from `gcc -S' shows that label is set
to fts64_set. Using __REDIRECT_NTH instead of __REDIRECT worked for me,
generating the right declaration.

Bug ID: 21291
Summary: pthread cancellation fails when contending lock
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: dimitri.staessens at ugent dot be
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 9930
--> https://sourceware.org/bugzilla/attachment.cgi?id=9930&action=edit
code example that reproduces the problem
We found that with the 2.25 release of glibc, sometimes pthread_cancel fails to
cancel threads that are contending a robust mutex. At least, that's what we
think is happening. It's not that easy to explain, so find attached a code
example that reproduces the problem.
In the code it has a TIMEOUT defined, increasing the value will reduce the
chances of the cancel failing as the threads are more likely to be in the
timedwait. On glibc 2.24 it works even with a timeout set to 0 (it is set to 0
in the attached source file).
We run the following commands:
gcc robust_test.c -lpthread -lrt -o robust_test
./robust_test
expected output is:
Initializing...
Starting threads...
Sleeping for one second...
Thread started...
Thread started...
Cancelling threads...
Threads finished.
Bye.
Which works fine on glibc 2.24-2 (Arch Linux). However, on glibc 2.25-1, it
hangs at "Cancelling threads...":
Initializing...
Starting threads...
Sleeping for one second...
Thread started...
Thread started...
Cancelling threads...
I hope this report is useful to you.
Sincerely,
Dimitri Staessens.

@Naresh, how have you tested? you modified locally /usr/include/bits/siginfo.h
or rebuilt glibc with the patch applied?
I've applied the patch, rebuilt glibc/gdb and it fails to build gdb:
| In file included from ../../gdb-7.11.1/gdb/nat/linux-ptrace.c:20:0:
| ../../gdb-7.11.1/gdb/nat/linux-ptrace.h:175:22:

Bug ID: 21295
Summary: GETAI(AF_UNSPEC) drops IPv6 addresses if nss module
does not support getaddrinfo4_r
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: glibc at kmeaw dot com
Target Milestone: ---
GETAI(AF_UNSPEC) only returns the IPv4 result
CVE-2016-3706 patch introduces a regression which disrupts connectivity
from IPv6-only to dual-stack hosts having an old libnss_dns library.
It affects users of nss modules which does not support new
getaddrinfo4_r interface — glibc falls back to using older
getaddrinfo{2,3}_r interfaces. This bug breaks connectivity
on IPv6-only hosts if you try to connect to a dual-stack
machine — only IPv4 addresses will be provided by getaddrinfo call.
How to reproduce:
Sample program:
#include <arpa/inet.h>
#include <netdb.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main() {
struct addrinfo *result;
struct addrinfo *res;
int error;
char *host = "ya.ru";
char buf[512];
/* resolve the domain name into a list of addresses */
error = getaddrinfo(host, NULL, NULL, &result);
if (error != 0) {
if (error == EAI_SYSTEM) {
perror("getaddrinfo");
} else {
fprintf(stderr, "error in getaddrinfo: %s\n",
gai_strerror(error));
}
exit(EXIT_FAILURE);
}
for (res = result; res != NULL; res = res->ai_next) {
if (res->ai_family == AF_INET)
inet_ntop(res->ai_family, &((struct sockaddr_in
*)res->ai_addr)->sin_addr, buf, sizeof(buf));
else if (res->ai_family == AF_INET6)
inet_ntop(res->ai_family, &((struct sockaddr_in6
*)res->ai_addr)->sin6_addr, buf, sizeof(buf));
else
continue;
puts(buf);
}
freeaddrinfo(result);
return 0;
}
Build and run program:
# gcc foo.c
# ./a.out | sort -u
Actual Result:
213.180.193.3
213.180.204.3
93.158.134.3
Expected Result:
213.180.193.3
213.180.204.3
2a02:6b8::3
93.158.134.3
This is because IPv6 results would get discarded after a successive call
to convert_hostent_to_gaih_addrtuple.

code example with mutexes
Dear,
we've been digging a bit deeper. It doesn't depend on the mutex being in shared
memory. The problem seems to happen only with a pthread_cond_timedwait using
the monotonic clock. I've added a new code sample, with the clock set to
CLOCK_MONOTONIC. Changing the clock to CLOCK_REALTIME has the threads cancel
correctly.
We've tested this using glibc 2.24 and 2.25 on the same Linux kernel, so we
think it's not a kernel problem.
Hope this helps to narrow things down.
best,
Dimitri

test file
Consider the following file sorttest.txt, pre-sorted in Unicode codepoint
order:
!
ｽﾞã–ら
ｾｰﾘï¾ï½¸ï¾žï¾Žï¾žï½°ï¾„ã¯
ﾓｴ
ï¿¥
ð€Ž
ð€˜
ð€›
ð«››
𫛞
𫛢
ð«›
𫛶
𫛸
ð«Ÿ·
𫟼
If I run "LC_COLLATE=C sort sorttest.txt", using the hard-coded C locale, the
output is unchanged -- that is, it is sorted in codepoint order as expected.
However, if I run "LC_COLLATE=C.UTF-8 sort sorttest.txt" on Ubuntu, which uses
a locale file defining collation straightforwardly in the codepoint order, I
get the following unexpected result:
ð€Ž
ð€˜

𫛢

To get more detail on what's going on, one can run:
$ LC_ALL=C.UTF-8 sort sorttest.txt | perl -CSAD -ne 'chomp; printf
"%s\tU+%05X\n", $_, ord'
ð€Ž U+1000E
ð€˜ U+10018
ð€› U+1001B
ð«›› U+2B6DB
𫛞 U+2B6DE
𫛢 U+2B6E2
ð«› U+2B6ED
𫛶 U+2B6F6
𫛸 U+2B6F8
ð«Ÿ· U+2B7F7
𫟼 U+2B7FC
! U+00021
ｽﾞã–ら U+0FF7D
ｾｰﾘï¾ï½¸ï¾žï¾Žï¾žï½°ï¾„㯠U+0FF7E
ﾓｴ U+0FF93
ï¿¥ U+0FFE5
Another example:
$ perl -CSAD -E 'for my $b (0, 0xF000, 0x10000) { for my $c (0x00, 0x01, 0x21)
{ $_ = $b + $c; printf "%s\tU+%05X\n", chr, $_} }' | LC_COLLATE=C.UTF-8 sort
U+00000
ð€€ U+10000
ð€ U+10001
ð€¡ U+10021
U+00001
! U+00021
 U+0F000
ï€ U+0F001
 U+0F021
The issue looks to be that codepoints above 0xFFFF come before the rest, except
that U+0000 somehow always comes first.
It's definitely not just the "sort" command that's broken. I first noticed this
issue in a PostgreSQL database that was using the C.UTF-8 locale's collation
order. Given the straightforwardness of the locale file in question
(/usr/share/i18n/locales/C on Ubuntu), it's hard to believe the fault lies
outside glibc.
The above commands were tested on Ubuntu 16.04 with glibc 2.23, but the same
issue has been reproduced on earlier and later versions of glibc (2.19, 2.24,
2.25).

Bug ID: 21304
Summary: make check fails with /usr/bin/install: cannot remove
'/usr/include/stdlib.h': Permission denied
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: nszabolcs at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
bug 20314 is not fixed: libstdc++ added std_abs.h which has the same issue. (i
noticed it when running make check a second time in the same build directory,
not sure why it works for the first time, but this is a nasty issue:
make subdir=nptl -C nptl ..=../ tests
make[2]: Entering directory `SRC/nptl'
/usr/bin/install -c -m 644 ../include/stdlib.h /usr/include/stdlib.h
/usr/bin/install: cannot remove '/usr/include/stdlib.h': Permission denied
make[2]: *** [/usr/include/stdlib.h] Error 1
and preprocessing nptl/tst-thread_local1.cc reveals that indeed std_abs.h
caused include_next <stdlib.h> to find /usr/include/stdlib.h and thus it gets
added to the make deps)
instead of playing whack a mole with libstdc++ headers, glibc should stop
including things into its tests that are not under the control of glibc (i see
no reason to create c++ threads to test c++ destructor semantics) and the
workaround hack in commit 9be4ecc5bbecb2fdbeee0c0d7af30e94517fd5d6 should be
reverted.

Could you please put together a strcoll-based test case that shows the issue?
That way I can take this upstream to discuss.

I'm assigning this to you because I know you're working on it and I don't want
anyone to do independent investigation without coming to you first.

Summary: clock_gettime(CLOCK_MONOTONIC_RAW) can and should use
rdtsc instructions instead of entering kernel through
VDSO
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: enhancement
Priority: P1
Component: libc

Target Milestone: ---
On a modern Intel Haswell CPU :
processor : 6
vendor_id : GenuineIntel
cpu family : 6
model : 60
model name : Intel(R) Core(TM) i7-4910MQ CPU @ 2.90GHz
siblings : 8
cpu cores : 4
with TSC Related CPU Capabilities:
( cpuinfo flags | tr ' ' '\n' | grep tsc )
tsc
rdtscp
constant_tsc
nonstop_tsc
tsc_deadline_timer
tsc_adjust
This loop does not print any number < 600 (600ns) :
struct timespec tsp1, tsp1;
unsigned int i = 10;
do
{ clock_gettime(CLOCK_MONOTONIC_RAW, &tsp1);
clock_gettime(CLOCL_MONOTONIC_RAW, &tsp2);
printf("%llu\n",
( ((unsigned long long)tsp2.tv_sec * 1000000000)
+ tsp2.tv_nsec
)
-( ((unsigned long long)tsp1.tc_sec * 1000000000)
+ tsp1.tv_nsec
) );
}while( --i );
This is really bad, since a simple rdtsc / rdtscp instruction
and conversion of its value using the same formula as
Linux's clocksource.c takes @ 15-20ns (see attached
ttsc.tar for proof of this).
It is possible to access the VDSO's
typedef struct vsyscall_gtod_data_s {
unsigned seq;
int vclock_mode;
U64_t cycle_last;
U64_t mask;
U32_t mult;
U32_t shift;
/* open coded 'struct timespec' */
U64_t wall_time_snsec;
gtod_long_t wall_time_sec;
gtod_long_t monotonic_time_sec;
U64_t monotonic_time_snsec;
gtod_long_t wall_time_coarse_sec;
gtod_long_t wall_time_coarse_nsec;
gtod_long_t monotonic_time_coarse_sec;
gtod_long_t monotonic_time_coarse_nsec;
int tz_minuteswest;
int tz_dsttime;
} Linux_GTOD_t;
extern Linux_GTOD_t vvar_vsyscall_gtod_data ;
This contains the live calculated and adjusted
'shift' and 'mult' values
used by the kernel to return the information
in a 'struct timespec *ts' in response to the
clock_gettime(CLOCK_MONOTONIC_RAW, ts) call,
so a user space libary, eg. glibc or a libIA64TSC.so
'rdtsc' library, could do something like:

The last function above can be called with @ 10-15ns latency to
return the timestamp as calculated according to the same
formula Linux uses to INITIALIZE the shift & mult values,
without entering the kernel.
It can be made more accurate if it uses the actual, UPDATED
shift & mult values stored in the vvar_vsyscall_gtod_data
in the VDSO .
Unfortunately, this is a '*ABS*' type symbol :
$ objdump -t $BLD/linux-4.10/arch/x86/entry/vdso/vdso64.so.dbg | grep
vvar_vdso_vsys
ffffffffffffe080 l *ABS* 0000000000000000
vvar_vsyscall_gtod_data
This is the offset of 'vsyscall_gtod_data' within the kernel,
so one has to subtract the value of 'vdso_vvar_page' from it,
and add the value of the base address of the VDSO in the process
to the result, to obtain the vvar_vsyscall_gtod_data address.
It can ONLY be looked up from inspection of the debuginfo data
of the VDSO .
Even parsing the VDSO from the AUXV at startup, as at :
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/vDSO?id=v3.8
does not help, because the absolute value is stripped out of the VDSO
linked into every executable.
I think GLIBC should be using rdtscp directly instead of calling
clock_gettime() through the VDSO, on platforms where all these
CPU capabilities are enabled:
tsc
rdtscp
constant_tsc
nonstop_tsc
and the VDSO debug object (vdso64.so.dbg) is at a well-known location
and can be used to lookup the vdso_vvar_page and vvar_vsyscall_gtod_data
values,
so that conversion from rdtsc / rdtscp result to a (seconds,nanosecond)
value is done in an IDENTICAL WAY to clock_gettime() in the kernel,
but entirely in user-space and WITHOUT having to lock around the
vvar_vsyscall_gtod_data, which is what causes the huge delay.
The CLOCK_MONOTONIC_RAW value is meant to be the monotonically
increasing UNADJUSTED raw timestamp counter anyway, so why should users
be forced to wait for locking so that adjustments can occur ?
It imposes a HUGE overhead and floor on the minimum amount of
time that can be measured by user-space processes on glibc
Linux systems.
Ubuntu's libc6 DOES redirect clock_gettime(CLOCK_MONOTONIC_RAW) calls to a
function that invokes rdtscp in user-space also - why can't GLIBC
do this ?
Minimum time taken between clock_gettime() calls on my system: 600ns
Minimum time taken to invoke rdtsc & convert result : 8ns

Does your kernel actually implement CLOCK_MONOTONIC_RAW in the vDSO? I think
upstream doesn't do that.
I don't see why your proposed performance enhancement couldn't be applied to
the vDSO itself. I don't think it is a good idea to put detailed knowledge
about system clocks into glibc.

--- Comment #2 from Jason Vas Dias <jason.vas.dias at gmail dot com> ---
I am using the unmodified Linux 4.10.0 (latest stable git tag).
In arch/x86/entry/vdso/vclock_gettime.c,
clock_gettime(CLOCK_MONOTONIC_RAW,&ts)
is handled by :
notrace static int __always_inline do_monotonic(struct timespec *ts)
{
unsigned long seq;
u64 ns;
int mode;
do {
seq = gtod_read_begin(gtod);
mode = gtod->vclock_mode;
ts->tv_sec = gtod->monotonic_time_sec;
ns = gtod->monotonic_time_snsec;
ns += vgetsns(&mode);
ns >>= gtod->shift;
} while (unlikely(gtod_read_retry(gtod, seq)));
ts->tv_sec += __iter_div_u64_rem(ns, NSEC_PER_SEC, &ns);
ts->tv_nsec = ns;
return mode;
}
The problem is, it is doing locking here in gtod_read_begin() .
to clarify :
$ objdump -t $BLD/linux-4.10/arch/x86/entry/vdso/vdso64.so.dbg | grep vvar
ffffffffffffe000 l *ABS* 0000000000000000 vvar_page
ffffffffffffe000 l .hash 0000000000000000 vvar_start
ffffffffffffe080 l *ABS* 0000000000000000 vvar_\
vsyscall_gtod_data
So you can get the base address of the VDSO & VVAR page of any process:
$ egrep '\[vdso|vvar\]' /proc/$$/maps
7fff5d122000-7fff5d124000 r--p 00000000 00:00 0 [vvar]
7fff5d124000-7fff5d126000 r-xp 00000000 00:00 0 [vdso]
So in this case, vvar_vsyscall_gtod_data is at :
(0xffffffffffffe080 - 0xffffffffffffe000) + 0x7fff5d122000
You can cast this to a pointer to 'struct vsyscall_gtod_data' (*p)
in GDB and it prints a valid struct, with vclock_mode set to 1
(VCLOCK_MODE_TSC)
and shift and mult member values that are very close to those calculated in
the function above (derived from the function in clocksource.c), but which ARE
dynamically adjusted, even on machines with constant_tsc and nonstop_tsc
enabled.
The precise TSC frequency may be unavailable on machines with cpuid level <
0x15 , but is always calibrated by linux during startup and stored in
'tsc_khz':
$ ksym tsc_khz 4
ffffffff82c04774 tsc_khz 002c25f3
(ksym is a little script I wrote to use /proc/kallsyms and /proc/kcore
to use objdump to lookup the value of a symbol, of size 2nd argument,
in the running kernel - so tsc_khz is 2893299 , or near the rated frequency
of the CPU: 2.9Ghz -
this is the initial value used by the ia64_tsc_calc_mult_shift() function.
).
I think GLIBC should access the (vvar_syscall_gtod_data)->shift and ->mult
values to calculate clock_gettime(CLOCK_MONOTONIC_RAW, &tsp) values in
user-space in the same way the kernel does:
struct vsyscall_gtod_data *gtod = linux_vdso_vvar_vsyscall_gtod_lookup() ;
U64_t tsc_ticks = x86_64_rdtscp() ;
U64_t s_ns = (tsc_ticks * gtod->mult) >> gtod->shift;
tsp->tv_sec = (s_ns >> 32) & ((1UL<<32)-1);
tsp->tv_nsec =(s_ns & ((1UL <<32)-1)));
RE:
> I don't see why your proposed performance enhancement couldn't be applied to
> the vDSO itself.
It is unlikely that the kernel developers would agree to abandon locking
around the vsyscall_gtod_data here .
Strictly, they are correct, in that it is possible that a process could
be updating gtod->mult and gtod->shift as another process reads them
without locking . But since updates to these integers are atomic,
invalid values for them won't be read by unlocked readers , and
it is incredibly unlikely that both gtod->mult AND gtod->shift
would be updated so that mismatched values for them would be
obtained by an unlocked reader .
I think taking the miniscule risk that once in a blue moon a reader
might get mismatched shift & mult values is far, far outweighed by
the vast benefits users would gain by being able to measure times
less than 600ns or so.
>I don't think it is a good idea to put detailed knowledge about system clocks >into glibc.
Idealogically, perhaps, but we are not in a perfect world .
Users of a modern POSIX operating system on a 2.9-3.9Ghz machine
should expect to be able to measure the time with a granularity
of less then 500ns.

Actually, I think only the gtod->mult ever gets updated,
not the gtod->shift; so unlocked readers might sometimes
read a gtod->mult value that has just been updated and
get its old value - this does not seem to me to be a
major disincentive to unlocked clock_gettime(CLOCK_MONOTONIC_RAW,&ts)
readers, because they want the unadjusted value anyway .

Why do you think the code ends up there? CLOCK_MONOTONIC is not
CLOCK_MONOTONIC_RAW. Profiling matches that—there is no fast path in the vDSO
for CLOCK_MONOTONIC_RAW.

--- Comment #4 from David Kamholz <lautgesetz at gmail dot com> ---
Isn't using the sort command already "strcoll-based"? I've checked its source,
and it relies on strcoll for sorting. The fact that sort and PostgreSQL produce
identical results suggests it's not a quirk or bug of either implementation,
but rather a result of their shared reliance on strcoll.
By upstream do you mean Ubuntu, or what? It's hard to imagine there's an issue
with how Ubuntu defined the collation order, since it's literally just a list
of thousands of codepoints in order. Conceivably there's something wrong with
the locale generated from it, but since they just use locale-gen, I suspect
that the attached C.UTF-8 locale definition and test file are enough to
reproduce the issue with any glibc.

testcase / demo of problem
A simple testcase / demo of the issue :
$ tar -xpf ttsc.tar
$ cd ttsc
$ make
...
$ ./ttsc1
max_extended_leaf: 80000008
has tsc: 1 constant: 1
Invariant TSC is enabled: Actual TSC freq: 2.893299GHz - TSC adjust: 1.
ts2 - ts1: 157 ts3 - ts2: 87 ns1: 0.000000755 ns2: 0.000003167
ts3 - ts2: 184 ns1: 0.000000763
ts3 - ts2: 19 ns1: 0.000000729
ts3 - ts2: 20 ns1: 0.000000783
ts3 - ts2: 22 ns1: 0.000001284
ts3 - ts2: 23 ns1: 0.000001344
ts3 - ts2: 21 ns1: 0.000001221
ts3 - ts2: 21 ns1: 0.000001216
ts3 - ts2: 21 ns1: 0.000001025
ts3 - ts2: 28 ns1: 0.000001196
ts3 - ts2: 18 ns1: 0.000001237
t1 - t0: 104579 - ns2: 0.000107727
The number shown as 'ts3 - ts2' is the difference between
ts2=IA64_s_ns_since_start();
ts3=IA64_s_ns_since_start();
obtained by invoking rdtscp in user space,
and ns1 is the difference between the
timestamps in tsp1 & tsp2 after:
clock_gettime(CLOCK_MONOTONIC_RAW,&tsp1);
clock_gettime(CLOCK_MONOTONIC_RAW,&tsp2);
The total at the end (t1 - t0) is the total
elapsed time as measured by rdtscp in userspace: 104579ns
versus the total measured by clock_gettime : 107727ns
which are very close; they would be closer if precisely
the same values were used for gtod->mult and gtod-shift
were used as the kernel uses, but this version uses the
values calculated from tsc_khz , not the vvar_vdso_gtod_data
values.
So now I need to know : will a future version of glibc
ever consider providing an interface to rdtscp in user-space
for such platforms as my machine ?
If so, I will submit a patch to make glibc do this.
If not, I will need to expand ttsc.tar into a full featured
'libIA64_tsc.so' library, which will be used by my code if
it runs on a glibc system, but not if on an Ubuntu/Debian libc6
system, because as already noted Ubuntu + Debian already redirect
calls to clock_gettime(CLOCK_MONOTONIC_RAW,&ts) to a function that
does an unlocked 'rdtscp' instruction in userspace.

It's easier to analyze and pass the test around if it's a single C source file
that can be compiled and used to verify the problem. In this case I'm asking
for your help to reduce the problem down to the smallest possible test. And the
answer is "No" in some versions of sort don't use strcoll, they had custom
collation code, though modern sort should, but may not depending on distro
patches.

By upstream I mean libc-alpha@sourceware.org. There might be a problem in the
forward sorting.

I think you should propose a kernel patch which adds CLOCK_MONOTONIC_RAW
support first. I doubt that for architectures which can use CPU clocks with
constant rates, there is a need for locking for CLOCK_MONOTONIC_RAW. But Intel
engineers can probably help with that.
I don't think we will change glibc in the way you suggest because the vDSO data
structures appear to be kernel implementation details. And there is the issue
that glibc should not have to know about specific TSC properties.

--- Comment #7 from Jason Vas Dias <jason.vas.dias at gmail dot com> ---
Yes, it is as I suspected:
Linux is no longer a suitable platform for high performance
or real-time sensitive applications .
I'm moving on to FreeBSD & RTEMS (www.rtems.org).

in sysdeps/ieee754/dbl-64/e_pow.c:
in the function checkint() in at line 470, 472, 478 and 480
the integer shift-left uses undefined behaviour
because m and n is signed integer and the shift overflows:
if (k > 20)
{
if (n << (k - 20) != 0)
return 0; /* if not integer */
return (n << (k - 21) != 0) ? -1 : 1;
}
if (n)
return 0; /*if not integer */
if (k == 20)
return (m & 1) ? -1 : 1;
if (m << (k + 12) != 0)
return 0;
return (m << (k + 11) != 0) ? -1 : 1;

--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
In GNU C, a shift left or right by an amount in the range [0, width of
type - 1] is fully defined whether the value being shifted has a signed or
unsigned type. Only a shift by a negative amount, or an amount >= the
width of the type, is undefined.
This is not to say that cleanups to avoid certain cases that are undefined
in ISO C but not in GNU C should not be done, in order e.g. to support
building some glibc code with sanitization enabled, but such cases are not
bugs and should not be filed in Bugzilla.

commit 78c05814320cdc3377347f8e5fdbaa7cf5abf5b5
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Mar 27 15:07:38 2017 +0000
Define more termios.h macros unconditionally for alpha (bug 21277).
termios.h should define IUCLC for UNIX98 and older XSI standards. The
sysdeps/unix/sysv/linux/alpha version defines it only if __USE_MISC,
so causing some conform/ tests to fail.
Other versions define it unconditionally (I* being a reserved
namespace for this header); the API should be consistent between
architectures in the absence of a clear reason for it to differ (and
given that a symbol is part of the API on two architectures, I don't
see any reason for the feature test macros required ever to differ
between those architectures), so this patch makes the alpha version
define it unconditionally as well. Two non-POSIX macros alongside it,
IMAXBEL and IUTF8, are also defined unconditionally on other
architectures, so this patch makes them consistent by defining them
unconditionally on alpha as well.
Tested (compilation only) with build-many-glibcs.py.
[BZ #21277]
* sysdeps/unix/sysv/linux/alpha/bits/termios.h (IUCLC): Define
unconditionally.
(IMAXBEL): Likewise.
(IUTF8): Likewise.

Any update on this? Did you receive the program and were you able to reproduce
the issue? I just want to make sure it doesn't get lost. :-)

I have the reproducer, and I agree that we aren't sorting by using the rules in
the locale, at least it doesn't look like it.

--- Comment #8 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
As you noted it was fixed by c579f48 (Remove cached PID/TID in clone) on master
by removing the Linux getpid implementation altogether (and then use the
auto-generation syscall). I think for 2.24 the straightforward fix is just
remove getpid Linux implementation.

Fix the incorrect sorting order of a digraph and its geminated variant,
regression introduced by a faulty fix to bug 13547 in commit
b008d4c85619a753e441d7f473ba8af0db400bd6.
Fix two inconsistencies in sorting unusual capitalization of digraphs
(bug #18587).
Enable DIACRIT_FORWARD to work around bug #17750.
Sort foreign accents after the Hungarian ones.
Add extensive unittests containing all the examples from The Rules of
Hungarian Orthography and many more, including explanatory comments.

--- Comment #2 from dieter ferdinand <dieter.ferdinand at gmx dot de> ---
hello,
i try to get help from gentoo, but they can' help. you can read the bugreport
here: https://bugs.gentoo.org/show_bug.cgi?id=613304
it seems, the problem is, that more then one process get the message "no free
memory" or "out of memory" if one process need much memory in a short time.
after the problem happens again, i try to find some reason for the problem and
i see this:
1. chromium crashed with many open windows while i open more windows.
2. at the same time some other programs (wine,firefox, ...) which try to get
memory will crash at the same time
3. the amount of free memory is at this momen less then 500 MB, the available
memory is over 10 GB
4. after i close more then 10 tabs in chromium i can reload it and open some
new windows without crash chromium imediadly
it seems, that at the most time, this problems happens, one program need to
much memory or need much memory in a short time because chromium runs over 10
seconds before it crash again after a restart so i can close some tabs before i
must restart it again.
before i update my system i use chrome with 32 bit and i have much more windows
open as in chromium. after the update chrome crash to often so i can't use it
again.
there are some important questions:
- how can i check how many real memory chromium needs and is this memory
reserved for the masterprocess or the threats or subprocesses and how many
memory can a process use in this different situations ? i don't know!
- why can't other process allocate memory if one process runs in out of memory
while it is a 32bit process?
normaly every process should be able to use 2 GB or more memory without making
problems, if one process will get to much memory.
i think, tghis must be a bug, but i don't know where. i think glibc or kernel.
goodby

Bug ID: 21326
Summary: C99 functions are not declared for C++11 and later if
_GNU_SOURCE is not predefined by g++
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jwakely.gcc at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Whether the following names are declared by glibc depends on __USE_ISOC99, but
not __USE_ISOCXX11. They are only declared for C++ programs because g++
unconditionally pre-defines _GNU_SOURCE for all compilations on GNU targets.
I want G++ to move away from predefining _GNU_SOURCE, because causes many
problems, e.g. non-standard names such as M_PI are always declared in C++
programs. Before we could do that, glibc would need to ensure all C99 functions
that are also part of C++11 would be declared for C++ code, without relying on
_GNU_SOURCE.
That could be done by either making many changes like this:
--- a/ctype/ctype.h
+++ b/ctype/ctype.h
@@ -126,7 +126,7 @@ extern int toupper (int __c) __THROW;
/* ISO C99 introduced one new function. */
-#ifdef __USE_ISOC99
+#if defined __USE_ISOC99 || __USE_ISOCXX11
__exctype (isblank);
#endif
Or simply:
--- a/include/features.h
+++ b/include/features.h
@@ -243,6 +243,7 @@
#if ((defined __cplusplus && __cplusplus >= 201103L) \
|| defined __GXX_EXPERIMENTAL_CXX0X__)
# define __USE_ISOCXX11 1
+# define __USE_ISOC99 1
#endif
/* If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
The former approach is already used in a very small number of places:
stdlib/stdlib.h:462:#if defined __USE_ISOC11 || defined __USE_ISOCXX11
stdlib/stdlib.h:484:#if defined __USE_ISOC11 || defined __USE_ISOCXX11
wcsmbs/uchar.h:40:#if defined __GNUC__ && !defined __USE_ISOCXX11
I can provide patches if you tell me which direction would be preferred.
The ISO C and ISO C++ names that are not declared by glibc when G++ doesn't
predefine _GNU_SOURCE are:
FP_INFINITE
FP_NAN
FP_NORMAL
FP_SUBNORMAL
FP_ZERO

Bug ID: 21327
Summary: Libstdc++ would like another way to get some POSIX
declarations that it currently gets via _GNU_SOURCE
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jwakely.gcc at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Related to PR 21326, if G++ doesn't predefine _GNU_SOURCE then the following
POSIX names are also not visible:
PTHREAD_MUTEX_RECURSIVE
pthread_mutex_timedlock
pthread_mutexattr_settype
pthread_rwlock_destroy
pthread_rwlock_init
pthread_rwlock_rdlock
pthread_rwlock_tryrdlock
pthread_rwlock_trywrlock
pthread_rwlock_unlock
pthread_rwlock_wrlock
uselocale
This is a different case from PR 21326 because these names are not part of ISO
C++, and so it's entirely correct for them to only be declared when an
appropriate feature test macro is defined. However, libstdc++ relies on these
features, so a "backdoor" would be needed for libstdc++ to get access to them
without predefining _GNU_SOURCE.
One approach would be a new __GLIBCXX_SOURCE feature test macro that g++ could
define to get _only_ the pieces needed by libstdc++, and not everything else
that _GNU_SOURCE declares.
Another would be to provide non-standard names for these features, so libstdc++
could use them via other names.
There's no urgency for this. I plan to start work on it after GCC 7 is
released, aiming for GCC 8.

--- Comment #1 from Jonathan Wakely <jwakely.gcc at gmail dot com> ---
On a related topic, there is this comment in features.h
/* This is to enable compatibility for ISO C++11.
So far g++ does not provide a macro. Check the temporary macro for
now, too. */
#if ((defined __cplusplus && __cplusplus >= 201103L) \
|| defined __GXX_EXPERIMENTAL_CXX0X__)
# define __USE_ISOCXX11 1
#endif
Should it define some other macro? Isn't __cplusplus the right thing to check?

If you're expecting something like __STDC_VERSION__ for C++, that's exactly
what __cplusplus is, so I don't know what "So far g++ does not provide a macro"
means.
However, that reminds me of another alternative solution to the main problem,
G++ could predefine __STDC_VERSION__ to 19901L for C++11 and C++14, and to
201112L for C++17. That would cause glibc to declare the C library functions
that C++ wants.
The C++ standard says:
"Whether __STDC_VERSION__ is predefined and if so, what its value is, are
implementation-defined."
So it would be OK for G++ to do that, as a way of requesting libc to declare
the corresponding features.

I think __USE_ISOC99 and __USE_ISOC11 should be defined for whatever C++
versions incorporate the relevant C library versions.

--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
I think the design needs to be discussed on libc-alpha, not in Bugzilla.
My starting point would be that all relevant API symbols used in libstdc++
headers should get implementation-namespace API names, exported under some
feature test macro, and that all relevant ABI symbols used in either
libstdc++.so or via code in headers should get implementation-namespace
ABI names (at public symbol versions). (Relevant meaning used in the
implementation of libstdc++ features from standard C++, as opposed to
libstdc++ features that are GNU extensions to standard C++. And by
implementation-namespace I strictly mean not conflicting with symbols that
users are allowed to use in their standard C++ programs, whether the
technology used is __* symbols or ways to ensure symbol references bind to
particular symbol versions without preemption by user code or something
else.)
Cf. Florian's proposal
<https://sourceware.org/ml/libc-alpha/2016-10/msg00294.html> (much of the
discussion was in November).

Summary: strcpy/strncpy suffering performance downgrade with
short string copy from glibc2.15
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: string

Patch and testcase
Hi,
Once upgrading the glibc from 2.11 to 2.17, we observed about 30% performance
downgrade in the new glibc2.17 version in the Libmicro benchmark strcpy tool
with copying short strings e.g. 10 bytes which is really a common usage of
strcpy.
We use the same x86_64 machine with cpu Intel(R) Xeon(R) CPU E5-2620 v4 @
2.10GHz and not any performance related configuration differences with the two
glibc building. And the cpus were also adjusted to performance mode when we
executed the Libmicro strcpy test case on the same cpus via taskset. However,
still the negative result.
Digging into the code, we found quite big changes in the x86_64 strcpy
implementation. And later we picked the code causes the performance downgrade
with short string which length less than 32 bytes. In the 2.17 code, strcpy
will step in the STRCPY_SSE2_UNALIGNED disassemble code. Different with the
2.11 code , the cod in 2.17 do ‘add’ and ‘cmp’ to make the strcpy with source
string address 6 LSB less than 0x20 to jmp to ‘SourceStringAlignmentLess32’
which most cases will be matched, so is the Libmicro test case. In the
‘SourceStringAlignmentLess32’ code, it uses a ‘movdqu’ to copy 16 bytes source
string to xmm1 which causes the performance downgrade.
We understand that since the source address maybe not 16 bits aligned, it’ OK
to copy the string to xmm1 first then to search the ‘\0’. However, in the
glibc2.11 strcpy code, it does the alignment first, then does the ‘\0’ search
direct with the ‘rsi’ register recorded memory. Not any copies to xmm0/1
register are involved. And we can also find the glibc2.11 legacy code dealing
with the source address unaligned with 16 bits cases next to the
‘SourceStringAlignmentLess32’ jump label. The legacy code works better always
but now it becomes just serving the source string with 6 LSB range from 0x21 to
0x3f.
The ‘new’ ‘SourceStringAlignmentLess32’ code also make us confused since it
seems strcpy can also work without it based on our analysis. We created a test
case with different alignments and lengths to verify if strycpy would work
correctly without it. So it does. And the short 10 bytes string copy also get
20+% performance up with the Libmicro testcase. As the code don’t make any
sense and short byte string copy always be used high frequency, maybe it’s
better to comment out the code for strcpy, and so is for strncpy. We checked
the latest code still using the same code as 2.17, so we created a patch based
on the latest version to make Virgo happy.
You can get Libmicro benchmark tool below:
https://java.net/projects/libmicro/sources
And the benchmark command we are using below:
taskset -c x-y ./bin-x86_64/strcpy -E -C 200 -L -S -W -N strcpy_10 -s 10 -I 5
The patch and test code for verify the patch as attachment.
Please help to confirm in case any incorrect.
Thank you.
BR,
Mou

Bug ID: 21338
Summary: mallopt M_ARENA_MAX doesn't set the maximum number of
arenas
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: laanwj at gmail dot com
Target Milestone: ---
Commit be7991c0705e35b4d70a419d117addcd6c627319 (which is in version 2.25)
introduced helper functions for setting arena_max, arena_test and other malloc
parameters. However it contained a typo in a switch statement in
__libc_mallopt, which results in that M_ARENA_MAX sets arena_test instead.
This has the result that setting mallopt M_ARENA_MAX or env MALLOC_ARENA_MAX no
longer sets the maximum number of arenas.

commit 622222846a2e6ffbcd02cb46cb5f29c48fe4a466
Author: Wladimir J. van der Laan <laanwj@gmail.com>
Date: Sat Apr 1 12:39:09 2017 +0530
Call the right helper function when setting mallopt M_ARENA_MAX (BZ #21338)
Fixes a typo introduced in commit
be7991c0705e35b4d70a419d117addcd6c627319. This caused
mallopt(M_ARENA_MAX) as well as the environment variable
MALLOC_ARENA_MAX to not work as intended because it set the
wrong internal parameter.
[BZ #21338]
* malloc/malloc.c: Call do_set_arena_max for M_ARENA_MAX
instead of incorrect do_set_arena_test

You need to report this to the libvpx developers.
It's also odd that a supposedly-ASAN-enabled build does not have an ASAN
interceptor for fwrite. The libvpx build system is non-standard, so I haven't
investigated this further.

Bug ID: 21349
Summary: race condition between dl_open and rtld lazy symbol
resolve
Product: glibc
Version: 2.20
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: maninder1.s at samsung dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Issue is race condition between add_name_to_object & _dl_name_match_p.
One threads calling dlopen which further calls add_name_to_object &
other thread trying to resolve RTLD_LAZY symbols through
_dl_runtime_resolve which further calls _dl_name_match_.
_dl_name_match_p checks if libname->next is valid, then it assumes
libname->next->name to be valid. Also add_name_to_object initialized
name first and then sets valid next pointer.
Thread 1: dlopen ----> add_name_to_object
Thread 2: _dl_runtime_resolve ---> _dl_name_match_p
There is no synchronization mechanism between these two threads.
Thread 1 Thread 2
Writer Code: add_name_to_object() | Reader Code:
_dl_name_match_p()
|
newname->name = memcpy( ...) | struct libname_list *runp =
map->l_libname;
newname->next = NULL; | while (runp != NULL)
newname->dont_free = 0; | if (strcmp (name, runp->name)
== 0)
lastp->next = newname; | return 1;
| else
| runp = runp->next;
If there is any instruction reordering happens in writer side as lastp->next
updated before newname->name then we can face issue in reader side.
We have been facing issue in reader side where we get runp->next as valid but
runp->next->name is NULL, which results in NULL pointer access in strcmp but
when we check coredump then we see runp->next->name is valid.
so we are suspecting race condition.

Call the right helper function when setting mallopt M_ARENA_MAX (BZ #21338)
Fixes a typo introduced in commit
be7991c0705e35b4d70a419d117addcd6c627319. This caused
mallopt(M_ARENA_MAX) as well as the environment variable
MALLOC_ARENA_MAX to not work as intended because it set the
wrong internal parameter.
[BZ #21338]
* malloc/malloc.c: Call do_set_arena_max for M_ARENA_MAX
instead of incorrect do_set_arena_test

posix_spawn: use a larger min stack for -fstack-check [BZ #21253]
When glibc is built with -fstack-check, trying to use posix_spawn can
lead to segfaults due to gcc internally probing stack memory too far.
The new spawn API will allocate a minimum of 1 page, but the stack
checking logic might probe a couple of pages. When it tries to walk
them, everything falls apart.
The gcc internal docs [1] state the default interval checking is one
page. Which means we need two pages (the current one, and the next
probed). No target currently defines it larger.
Further, it mentions that the default minimum stack size needed to
recover from an overflow is 4/8KiB for sjlj or 8/12KiB for others.
But some Linux targets (like mips and ppc) go up to 16KiB (and some
non-Linux targets go up to 24KiB).
Let's create each child with a minimum of 32KiB slack space to support
them all, and give us future breathing room.
No test is added as existing ones crash. Even a simple call is
enough to trigger the problem:
char *argv[] = { "/bin/ls", NULL };
posix_spawn(NULL, "/bin/ls", NULL, NULL, argv, NULL);

posix_spawn: use a larger min stack for -fstack-check [BZ #21253]
When glibc is built with -fstack-check, trying to use posix_spawn can
lead to segfaults due to gcc internally probing stack memory too far.
The new spawn API will allocate a minimum of 1 page, but the stack
checking logic might probe a couple of pages. When it tries to walk
them, everything falls apart.
The gcc internal docs [1] state the default interval checking is one
page. Which means we need two pages (the current one, and the next
probed). No target currently defines it larger.
Further, it mentions that the default minimum stack size needed to
recover from an overflow is 4/8KiB for sjlj or 8/12KiB for others.
But some Linux targets (like mips and ppc) go up to 16KiB (and some
non-Linux targets go up to 24KiB).
Let's create each child with a minimum of 32KiB slack space to support
them all, and give us future breathing room.
No test is added as existing ones crash. Even a simple call is
enough to trigger the problem:
char *argv[] = { "/bin/ls", NULL };
posix_spawn(NULL, "/bin/ls", NULL, NULL, argv, NULL);

I don't see how this could make a difference because the answer and anslen
variables are dead at this point.

Can you provide more information how to reproduce the leak? Thanks.

Can you reproduce this at will? In this case, it would be very helpful to have
a capture of the DNS queries and responses.
Do you have any peculiar /etc/resolv.conf or RES_OPTIONS settings? What does
the hints structure for getaddrinfo look like?

Yes, I can reproduce this at will. resolv.conf only contains the this:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.8.8
Where 8.8.8.8 is the Google DNS server. It also fails when other DNS servers
are utilized.
I can capture the DNS traffic for you when this occurs. tcpdump capture Ok?

> I can capture the DNS traffic for you when this occurs. tcpdump capture Ok?
Yes, please do a binary (pcap file) capture with “-s 0†(complete packets).
You should limit the capture with “host 8.8.8.8â€, so that both UDP, fragmented
UDP, and TCP packets are included.
Capturing strace output at the same time would be helpful, too, in case the
stub resolver performs unexpected system calls which are not reflected in the
network traffic.
How close are your sources to upstream glibc 2.19? I wonder if this could be a
faulty backport.

--- Comment #10 from Rob Krakora <rob.krakora at bluepillar dot com> ---
The leak is occurring in the eglibc 2.19 code below...however, in the glibc
2.25 code further below there is some code added to indicated to the layers
above that a malloc has occurred which would negate the my proposed patch.
eglibc 2.19 and glibc 2.19 are closer and glibc 2.19 does not have the code to
indicate to the layers above that a malloc has occurred so it could possibly
have a leak???
eglibc 2.19:
if (*thisanssizp < MAXPACKET
/* If the current buffer is not the the static
user-supplied buffer then we can reallocate
it. */
&& (thisansp != NULL && thisansp != ansp)
#ifdef FIONREAD
/* Is the size too small? */
&& (ioctl (pfd[0].fd, FIONREAD, thisresplenp) < 0
|| *thisanssizp < *thisresplenp)
#endif
) {
/* Always allocate MAXPACKET, callers expect
this specific size. */
u_char *newp = malloc (MAXPACKET);
if (newp != NULL) {
*thisanssizp = MAXPACKET;
*thisansp = newp;
}
}
glibc 2.25:
if (*thisanssizp < MAXPACKET
/* If the current buffer is not the the static
user-supplied buffer then we can reallocate
it. */
&& (thisansp != NULL && thisansp != ansp)
#ifdef FIONREAD
/* Is the size too small? */
&& (ioctl (pfd[0].fd, FIONREAD, thisresplenp) < 0
|| *thisanssizp < *thisresplenp)
#endif
) {
/* Always allocate MAXPACKET, callers expect
this specific size. */
u_char *newp = malloc (MAXPACKET);
if (newp != NULL) {
*thisanssizp = MAXPACKET;
*thisansp = newp;
if (thisansp == ansp2)
*ansp2_malloced = 1;
}
}

That is not it...adding the code from my previous reply does not fix the leak.
Only the code change I originally proposed fixes it...hmmm....

If you want to continue using 2.19 you are on your own. Unless you can
reproduce it with 2.25 this is a WONTFIX.

We are moving to Yocto Krogoth which employs glibc 2.23 instead of eglibc 2.19
in a couple of months. I will run the same test and see if the leak exists
there.

--- Comment #16 from Florian Weimer <fweimer at redhat dot com> ---
The announcement of CVE-2015-7547 said:
“
- Always malloc the second response buffer if needed.
- Requires fix for sourceware bug 16574 to avoid memory leak.
commit d668061994a7486a3ba9c7d5e7882d85a2883707
commit ab09bf616ad527b249aca5f2a4956fd526f0712f
â€
<https://www.sourceware.org/ml/libc-alpha/2016-02/msg00416.html>
Coincidentally, this regression originally delayed the disclosure of
CVE-2015-7547. The upstream glibc 2.19 branch already had the fix for bug
16574 when CVE-2015-7547 was fixed, but our downstream 2.12 and 2.17 branches
still needed it.
If you have you own resolv backports, you should really try to get a
valgrind-clean pass with the external resolv test suite:
<https://pagure.io/glibc-resolv-tests>
I'm in the process of upstreaming the remaining tests.

--- Comment #17 from Rob Krakora <rob.krakora at bluepillar dot com> ---
Yes, I would LOVE to use Valgrind. However, we are on a ARM v5 and Valgrind
ARM support starts at v7. :) Thanks so much for your help and valuable
time!!!

I assume you could perform memory leak testing on a different architecture than
your production architecture. The important bit is to increase test coverage.
Architecture-specific memory leaks happen, but are not the norm.

--- Comment #8 from Shane Seymour <shane.seymour at hpe dot com> ---
I thought I'd chime in since I believe the independent report mentioned by
Florian was from me.
Although it's not a generic fix for the underlying issue for a class of
character sets that use shift in/shift out sequences (e.g. IBM930 and IBM933)
some of them work as expected and some don't (I can't remember which one did
ignore a duplicate shift in or out). For IBM930 the BODY macro looks in part
like:
#define BODY \
{ \
uint32_t ch = *inptr; \
uint32_t res; \
\
if (__builtin_expect (ch, 0) == SO) \
{ \
/* Shift OUT, change to DBCS converter. */ \
if (curcs == db) \
{ \
result = __GCONV_ILLEGAL_INPUT; \
break; \
} \
curcs = db; \
++inptr; \
continue; \
} \
if this line:
if (curcs == db) \
was changed to:
if (curcs == db && (! ignore_errors_p ())) \
Then a duplicate shift out sequence in IBM930 would not cause the iconv command
to loop forever with the -c option (the shift in code needs the same change).
But in general the issue could be resolved up by the code that does the
conversions not returning an error when being told ignore errors. In the above
example while it appears to be illegal to have duplicate shift in/out sequences
when ignoring errors the duplicate should probably just be consumed and
ignored.
Should there be a general rule that the character set conversion macros must do
something with their input when faced with something invalid and they've been
told to ignore errors? Then iconv doesn't need to know anything when set to
ignore errors and it shouldn't loop.
For non-variable size multi-byte character sets the converter at least it knows
based on the character set the number of bytes it should consume so it's easier
for it to skip past any error (e.g. IBM930 knows if it should skip one or two
bytes based on the current shift state).
I thought of these general rules when errors are ignored:
1. Character set converters using a fixed or know number of bytes will skip
forward one character when encountering an invalid character (includes
character sets that are always the one fixed size and character sets using
shift states between different size fixed characters)
2. Invalid structural data will be consumed (e.g. duplicate shift in/out states
in character sets like IBM930)
3. Variable size character sets will consume everything in from the start of a
character up to and including the byte that made the character invalid (e.g. in
SJIS if the sequence of bytes 0x81 0x20 was seen both bytes would be consumed
not just the 0x81 but that could instead easily be advance one byte and start
again).
Those rules are entirely open to discussion though - I've probably missed some
conditions that need to be covered. The downside would be that there are a lot
of macros to review to make sure that they would all follow a defined set of
rules and may it change their behaviour.
Anything following a conversion failure should really be considered undefined
anyway (as someone else said garbage in garbage out) so how bad data gets
treated can follow set rules as long as they are followed consistently by
everything.
Does it make more sense that the character set converters should decide what to
drop, skip or quitely consume when being told to ignore errors vs doing it
somewhere that doesn't really know much about any particular character set?

--- Comment #3 from Torvald Riegel <triegel at redhat dot com> ---
I do not remember who brought this up, but one can argue that the POSIX
requirements on synchronization only apply to function calls that do not fail.
This seems sensible to me. It means that trylocks that fail by returning EBUSY
do not imply any synchronization effects, so implementing lock acquisition
attempts in trylock with an atomic_compare_exchange_weak_acquire would be okay
(whose failure path has relaxed MO semantics and can fail spuriously).

--- Comment #4 from Torvald Riegel <triegel at redhat dot com> ---
See http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html,
subsection "Memory Synchronization":
"Unless explicitly stated otherwise, if one of the above functions returns an
error, it is unspecified whether the invocation causes memory to be
synchronized."
This allows for using just relaxed memory order when observing that a lock is
already acquired and returning EBUSY due to that; however, it is unclear
whether this allows for using a weak CAS that may fail spuriously (ie,
returning EBUSY because of a spurious failure).

Bug ID: 21357
Summary: unwind-dw2-fde deadlock when using AddressSanitizer
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: rabinv at axis dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
__deregister_frame_info_bases() calls free() while holding a mutex which is
also used from _Unwind_Find_FDE(). This leads to a deadlock if
AddressSanitizer uses _Unwind_Backtrace() from its free() implementation. Seen
on MIPS.

Will that effect sorting order of the sort command from GNU/Linux command line?
If yes, I'm waiting for that status to change to FIXED since 2014. :)
I'm sorry for not being able to participate with constructive comment but
hoping to keep this alive since last comment was made a year ago.
Thanks

--- Comment #9 from Shane Seymour <shane.seymour at hpe dot com> ---
Sorry I should add that the IBM930 example was just that (an example). That's
an illustration of a downstream issue not upstream since that code has been
changed for that conversion to ignore duplicate shift in shift out characters.
The same general class of issues exists in other things though. Should the
conversion routines be allowed to return errors when told to ignore them (or if
they do they can't return with the input pointer unchanged so forward progress
can always be guaranteed).

Had no idea it could work that way. This will save me a lot of trouble I'm
going trough write now when sorting Croatian text.
I'll try to contact you via e-mail because I have some more questions about
localization files in general and I'm thinking about changing one so I need
some help. Don't won't to spam this report as it serves different purpose.
I just hope to see hr_HR.utf8 in Debian soon.
Many thanks for help and effort.

Bug ID: 21359
Summary: ns_name_pack needs additional byte in destination
buffer
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
ns_name_pack contains an off-by-one error which causes it to fail when the
destination buffer has the exact required size.
This does not affect name resolution because res_nmkquery calls
ns_name_compress with a larger destination buffer.

Bug ID: 21360
Summary: snprintf %n does not conform to ISO C when characters
are not printed
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: vincent-srcware at vinc17 dot net
Target Milestone: ---
Consider the following example:
#include <stdio.h>
int main(void)
{
int r, n = -1;
r = snprintf (NULL, 0, "foo%n", &n);
printf ("%d %d\n", r, n);
return 0;
}
With glibc 2.24, I get 3 3 instead of the expected 3 0. Indeed, the glibc
manual (whose description seems equivalent to ISO C11) says for %n:
12.12.6 Other Output Conversions
--------------------------------
[...]
The '%n' conversion is unlike any of the other output conversions.
It uses an argument which must be a pointer to an 'int', but instead of
printing anything it stores the number of characters printed so far by
this call at that location.
but due to the size 0, nothing has been printed. Thus one should have n = 0.
Note that in its snprintf description:
The return value is the number of characters which would be
generated for the given input, excluding the trailing null.
"would be", thus the expected r = 3. There is no such "would be" for %n. In the
C11 draft I have, this is said in a similar way:
The snprintf function returns the number of characters that would
have been written had n been sufficiently large, [...]
The "had n been sufficiently large" is quite explicit. But again, there is no
such thing for %n.

Summary: resolv: Reduce advertised EDNS0 buffer size to guard
against fragmentation attacks

Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security+
When ENDS0 is enabled, glibc currently requests large DNS responses over UDP
(up to 65536 bytes). This is problematic because the randomized transaction ID
and source port randomization both protect only the first fragment in a
response.
As a partial countermeasure, the stub resolver should lower the advertised
buffer size to 1200 bytes (IPv6 minimum MTU of 1280 minus some tunnel
overhead). With some cooperation from the server, this should avoid
fragmentation.

configure: accept __stack_chk_fail_local for ssp support too [BZ #20662]
When glibc is compiled with gcc 6.2 that has been configured with
--enable-default-pie and --enable-default-ssp, the configure script
fails to detect that the compiler has ssp turned on by default when
being built for i686-linux-gnu.
This is because gcc is emitting __stack_chk_fail_local but the
script is only looking for __stack_chk_fail. Support both.
Example output:

implicitly enables -fstack-protector... no

--- Comment #1 from Andreas Schwab <schwab@linux-m68k.org> ---
The description only talks about the produced characters being discarded
instead of written to memory. The side effects of producing the output is
still performed. In case of lack of space the output stream is just the
equivalent of /dev/null.

x86-64: Improve branch predication in _dl_runtime_resolve_avx512_opt [BZ
#21258]
On Skylake server, _dl_runtime_resolve_avx512_opt is used to preserve
the first 8 vector registers. The code layout is
if only %xmm0 - %xmm7 registers are used
preserve %xmm0 - %xmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %zmm0 - %zmm7 registers
Branch predication always executes the fallthrough code path to preserve
%zmm0 - %zmm7 registers speculatively, even though only %xmm0 - %xmm7
registers are used. This leads to lower CPU frequency on Skylake
server. This patch changes the fallthrough code path to preserve
%xmm0 - %xmm7 registers instead:
if whole %zmm0 - %zmm7 registers are used
preserve %zmm0 - %zmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %xmm0 - %xmm7 registers
Tested on Skylake server.
[BZ #21258]
* sysdeps/x86_64/dl-trampoline.S (_dl_runtime_resolve_opt):
Define only if _dl_runtime_resolve is defined to
_dl_runtime_resolve_sse_vex.
* sysdeps/x86_64/dl-trampoline.h (_dl_runtime_resolve_opt):
Fallthrough to _dl_runtime_resolve_sse_vex.

commit b2e8c40afcb83f9a6dbbb543ce0951b6c890d350
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu Jan 5 17:35:53 2017 +0000
Fix MIPS n64 readahead (bug 21026).
As noted in bug 20126, MIPS n64 uses an incorrect implementation of
readahead intended for 32-bit systems. This patch adds a
syscalls.list entry to fix this. An updated version of the
consolidation patch
<https://sourceware.org/ml/libc-alpha/2016-09/msg00527.html> could
remove this syscalls.list entry again.
Tested with compilation (only) for mips64; the nature of the syscall
doesn't allow for a glibc test to detect this issue.
[BZ #21026]
* sysdeps/unix/sysv/linux/mips/mips64/n64/syscalls.list
(readahead): New syscall entry.
(cherry picked from commit 30733525c6867c160261db1afade6326000f9f75)

Target Milestone: ---
<net/if.h> and <linux/if.h> can't be included from the same file without
causing redeclaration of enums and structs. The case where <net/if.h> is
included first has already been fixed on the Linux side in commit
4a91cb61bb995. The reverse case has to be fixed on the GNU libc side.
Patch will follow on the mailing list.

Summary: resolv: Remove EDNS fallback

Status: NEW
Severity: normal

Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
Certain FORMERR responses set the RES_F_EDNS0ERR internal resolver flag, which
disables future EDNS queries. This is undesirable because it prevents the
application from obtaining DNSSEC data (until res_init is called).
I think we can remove all RES_F_EDNS0ERR handling from the code base because
EDNS is disabled by default anyway. Anyone who enables it explicitly will have
to make sure that their recursive resolver can handle EDNS queries (that is,
not respond with FORMERR; non-EDNS-enabled responses are fine).

Bug ID: 21370
Summary: RFE: strftime() needs a "convert to titlecase" flag
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: time
Assignee: unassigned at sourceware dot org
Reporter: digitalfreak at lingonborough dot com
Target Milestone: ---
As suggested in https://bugzilla.gnome.org/show_bug.cgi?id=658807 some
applications need another flag to be supported by strftime(). The flag should
convert the string being output to the titlecase. By "titlecase" I mean:
- if the first Unicode character is a digraph (or a ligature) then it should be
converted to its titlecase counterpart (the first character is uppercase, the
second is lowercase);
- if the first Unicode character is a regular single letter then it should be
converted to uppercase;
- if it is not a letter or not a lowercase letter then it should not be
modified;
- no other character will be modified.
It has been suggested that the flag character should be "*" (for example "%*A")
but I can't tell why this character has been chosen. It may be this or another
character.
Currently strftime() supports these similar flags:
- "^" converts all characters to uppercase;
- "#" swaps the case of all characters;
- "^#" should convert all characters to lowercase but it does not - see bug
15527.
This new flag will be useful when formatting dates in probably most of European
languages, except English, German, Greek, and probably few more.

--- Comment #5 from Rich Felker <bugdal at aerifal dot cx> ---
Perhaps I'm being redundant saying this again, but I believe that whether the
function synchronizes memory on failure (I agree that it doesn't have to) is a
separate issue from whether it's permitted to return an error when the
conditions for that error code are not met. The answer to the latter is no, but
there are subtleties to the condition itself that make the topic nontrivial
still.
I don't believe there is any viable argument for returning EBUSY simply due to
a weak cas, when the mutex was never locked or the semaphore value was never
zero, and regardless of any ordering (perhaps this is even a single-threaded
process!) the operation should succeed. Likewise if you have a strong cas, but
the cas failure is due to something that wouldn't preclude the operation from
succeeding (like waiting on a semaphore whose value is >1 from another thread),
this should not be able to cause EBUSY. The only case in which there is an
argument to be made that a "spurious" EBUSY is valid is when, despite a lack of
other operations that synchronize memory, some other side channel (like a pipe)
establishes an ordering whereby the operation "should have" succeeded.
If no such order-imposing operation is present at all, then I think it's clear
that you can "spuriously" fail whenever there's any possible ordering that
would have produced failure.

Summary: Missing timespec definition when compiled with
_XOPEN_SOURCE and _POSIX_C_SOURCE
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc

Target Milestone: ---
The following code snippet doesn't compile, but it does if time.h is included
first:
Code:
-----
#define _XOPEN_SOURCE 700
#define _POSIX_C_SOURCE 200112L
#include <sys/stat.h>
#include <time.h>
int main(int argc, char *argv[])
{
struct timespec ts;
return 0;
}
Error logs:
-----------
$ cc -c timespec_defined.c -o timespec_defined.o
In file included from /usr/include/sys/stat.h:101:0,
from timespec_defined.c:4:
/usr/include/bits/stat.h:91:21: error: field ‘st_atim’ has incomplete type
struct timespec st_atim; /* Time of last access. */
^~~~~~~
/usr/include/bits/stat.h:92:21: error: field ‘st_mtim’ has incomplete type
struct timespec st_mtim; /* Time of last modification. */
^~~~~~~
/usr/include/bits/stat.h:93:21: error: field ‘st_ctim’ has incomplete type

^~~~~~~
In file included from timespec_defined.c:4:0:
/usr/include/sys/stat.h:368:54: error: array type has incomplete element type
‘struct timespec’
extern int futimens (int __fd, const struct timespec __times[2]) __THROW;
I am not sure if this _XOPEN_SOURCE/_POSIX_C_SOURCE combo makes sense or not,
this is the test case I ended up with when debugging a build failure in
Buildroot/uclibc and wanting to compare with glibc. Anyway, the fact that it
compiles when time.h is included first makes me believe that there is at least
something odd and worth investigating.

The plan is to fix this by unbundling libidn from glibc.

Created attachment 9985
--> https://sourceware.org/bugzilla/attachment.cgi?id=9985&action=edit
Full back trace as printed by GDB.
I am using Pytorch, and have run into an issue where my processes consistently
hang while exiting. The GDB backtrace indicating that the process deadlocks in
__pthread_cond_destroy. This is apparently only an issue on glibc 2.25, and
multiple other users have encountered it. Here are some references:
* PyTorch bug I filed this morning:
https://github.com/pytorch/pytorch/issues/1233
* PyTorch forum post about the issue:
https://discuss.pytorch.org/t/archlinux-using-variable-backwards-appears-to-hang-program-indefinitely/1675/18
* Tweet about this issue:
https://twitter.com/pchapuis/status/842741282544017408
According to the tweet: "Apparently the deadlocks only happen with the
combination of PTHREAD_MUTEX_ERRORCHECK and condition variables." This tweet is
from another user encountering the issue, AFAIK Pierre (the author of the
tweet) was not using Pytorch.
When I GDB attach to a hung process, the tail part of the backtrace looks like
this:
Core was generated by `python'.
#0 0x00007fc08b1f0221 in futex_wait (private=<optimized out>, expected=12,

I will also add an attachment with the full backtrace as reported by GDB, and a
core file I generated.

The core dump is too large to attach, so I've uploaded it to:
http://monad.io/core.11899.xz . The core dump is 22M compressed, 665M
uncompressed.
I'm not sure how useful the core dump will be, but this core dump was generated
on a Fedora 26 system, which reports that my glibc is version 2.25-4.fc26. The
executable for the core dump is python3-3.6.0-22.fc26.

Pierre (author of the tweet I linked to) commented on the GitHub issue I linked
to, noting that he was encountering this bug in a regular C program with
pthreads (i.e. not with Pytorch).

Summary|Absolute symbol is handled |Absolute (SHN_ABS) symbols

--- Comment #3 from Maciej W. Rozycki <macro@linux-mips.org> ---
This is a bug in the dynamic loader, not the static linker, and has been
also observed in the course of PR ld/21375 investigation, which it is a
blocker for (due to the peculiarities of the MIPS psABI, and its implicit
GOT handling in particular).
We have a bug in the run-time loader in the handling of absolute symbols
(symbols relative to the special SHN_ABS section). Such symbols are
supposed to retain their numeric value across the static link and then
dynamic loading. However our run-time loader does not pay attention to
the special section index and treats absolute symbols like regular
symbols; in fact there is no mention of the SHN_ABS macro anywhere except
from its definition in the elf/elf.h header.
To reproduce with the `x86_64-linux-gnu' target use the following program
and recipe:
$ cat test.c
#include <stdio.h>
char *x (void);
int
main (void)
{
printf ("a: %p\n", x ());
return 0;
}
$ cat libtest.c
extern char a __attribute__ ((weak));
char *
x (void)
{
return &a;
}
$ gcc -fPIC -shared -Wl,--defsym=a=3 -o libtest.so libtest.c
$ gcc -o test test.c -Wl,-rpath,$(pwd) libtest.so
Here's the result obtained -- as you can see the GOT relocation and the
symbol table have both been set up correctly for `a':
$ readelf --relocs libtest.so
Relocation section '.rela.dyn' at offset 0x468 contains 9 entries:

-- again, the value of `a' printed is not 3.
This is contrary to the ELF gABI that mandates [1]:
"SHN_ABS
The symbol has an absolute value that will not change because of
relocation."
Further observations have been made in the course of discussion regarding
PR ld/20402, which is a corresponding static linker issue affecting some
targets.

It's not entirely clear that SHN_ABS symbols are permitted in ET_EXEC and
ET_DYN objects. The document also says, “In executable and shared object
files, st_value holds a virtual addressâ€, which rules out SHN_ABS and its
absolute address.

Thank you for your patches !!
I confirm - changes for mr_IN, bn_IN and hi_IN are correct.
As you have mentioned these things are corrected from CLDR. CLDR is widely used
not and accepted by all major vendor. CLDR changes must be correct, since it
has been done by more language specialist.
Last year, we did automation regarding updating Glibc to newest Unicode
version. i.e. updating particular files related to Unicode.
Same way, can we also do automation to update Glibc to CLDR latest version?
We need to think on this line.
Can you provide script you use for getting these changes listed? May be we can
start from there.

--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
This proposal conflicts with the ALTMON proposal (bug 10871). Some locales
currently use "%d of %B" as the date format (with a language-specific genitive
indicator instead of “ofâ€), but they would switch to "%d %B" (or perhaps "%d
%OB") to support elision in the genitive indicator. Applying titlecase
conversion to the ALTMON string would likely not give expected results.

I think SHN_ABS just means "not section relative", but that doesn't say
anything about the relation to the load address.

Make sure you are not relying on undefined behaviour. For example: "Attempting
to destroy a condition variable upon which other threads are currently blocked
results in undefined behavior."

--- Comment #2 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
No, I can't see any conflict and I'm pretty sure there isn't any. I didn't say
that all ALTMON locale data should be converted to the titlecase. What I meant
is that a new flag should be introduced and it would be optionally used by the
applications only if developers (or translators) want it.
The problem is that in many languages there is no rule which says that the
month names must always start with uppercase so they start with lowercase in
the locale database. But sometimes they must start with uppercase for other
reasons, for example because they are in the beginning of the sentence, appear
as a title, header, standalone, etc. So, for example:
"%B" - would produce "april" (I know this is against English rules but let's
assume for this example that English does not want always uppercase)
"%*B" - would produce "April"
"%A, %B %d" - would produce "wednesday, april 12" (doesn't it look kinda
weird?)
"%*A, %B %d" - would produce "Wednesday, april 12" (doesn't it look better?)
This can be combined with "O" flag from bug 10871 to achieve multiple results
in multiple languages: "Abril", "abril", "d’abril", "D’abril", "Avril",
"avril", "De avril", "de avril", "April", "april", "Aprila", "aprila",
"Kwiecień", "kwiecień", "kwietnia".
Similarly, ALTMON proposal does not conflict with the existing flags: "^" and
"#".

--- Comment #6 from Maciej W. Rozycki <macro@linux-mips.org> ---
Florian, Andreas --
I think there is nothing in the spec that would make the interpretation
of SHN_ABS different or forbidden for dynamic load vs static link.
Besides, there is no other way to define a preemptible constant, and
treating link-time constants as relative expressions at the load time
makes no sense to me -- what would be the purpose?
Florian: the spec has a second sentence following one you've quoted:
"In executable and shared object files, st_value holds a virtual address.
To make these files' symbols more useful for the dynamic linker, the
section offset (file interpretation) gives way to a virtual address
(memory interpretation) for which the section number is irrelevant."
which I think provides a further explanation of what the purpose of the
change of the interpretation is, i.e. making a section offset into a
virtual address (of which `st_value' of absolute symbols is neither) to
make the implementation of a dynamic loader easier. I'd take the lack
of an explicit mention of the SHN_ABS special case here as an oversight,
though not a very serious one as other parts of the specification already
cover absolute symbols.
Andreas: I think the spec is clear, stating in two places respectively:
"SHN_ABS
This value specifies absolute values for the corresponding reference.
For example, symbols defined relative to section number SHN_ABS have
absolute values and are not affected by relocation."
and:
"SHN_ABS
The symbol has an absolute value that will not change because of
relocation."

My concern is that “De avril†and “D'abril†may or may not be proper titlecase
(as would be needed in this context). “de Avril“ or “d'Abril†might be
required in a calendar context.

It looks like thread 3 and thread 4 are both waiting on a condition variable
and thread 1 call pthread_cond_destroy on it. Also based on the bug report
pytorch referenced bug, it indeed looks like an application issue [2].
If you have well defined example which trigger this very issue it would be
helpful, otherwise debug indicates you are relying on undefined behavior and I
will close this bug.

Consolidate Linux mmap implementation (BZ#21270)
This patch consolidates all Linux mmap implementations on default
sysdeps/unix/sysv/linux/mmap{64}.c one. To accomodate all required
architecture specific requeriments a new internal header is created
(mmap_internal.h) where each architecture add its specific code
requirements. Currently only x86_64 (to define MMAP_PREPARE to add
MAP_32BITS), s390 (which have a different kernel ABI for mmap), m68k
(which have variable minimum page sizes), and MIPS n32 (which zero
extend the offset to handle negative one correctly) redefine the new
header.
The patch also fixes BZ#21270 where default mmap64 on architectures
which uses mmap2 silent truncates large offsets value (larger than
1 << (page shift + 8 * sizeof (off_t)) or 1<<44 on architectures with
4096 bytes page size). The new consolidate implementation returns
EINVAL as allowed by POSIX.
It also adds a tests for on current tst-mmap-offset one. I have run
a full make check on x86_64, x86_64-32, i686, aarch64, armhf, powerpc,
powerpc64le, sparc64, and sparcv9 without any regressions. I also ran
some basic tests (tst-mmap-offset) on sh4, m68k, and on qemu simulated
MIPS32 and MIPS64.

--- Comment #4 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
I'd like the people from specific language communities come and speak here
because I suspect such languages may not exist. :-) I'm aware that it may take
many years and I'm not in a hurry with this bug.
But let's assume that such language exists. Still it looks to me more than
like an incomplete solution or another missing feature rather than a conflict.
It shouldn't be hurting for anyone if an _optional_ feature to capitalize the
first letter is added.
If they need something like "de Avril" or "d'Abril" then probably besides
"capitalize the first letter" flag they would also need:
- capitalize the first letter of every word,
- capitalize the first letter of the second word (or more precisely: of the
main word).
Or maybe it would be easier to:
- fix the bug 15527,
- change all locale data to the proper titlecase so they will be always
titlecased by default (like in English),
- those who want lowercase would use "^#" explicitly,
- those who want all uppercase would use "^" etc.
So for example (Catalan):
"%A, %d %B" -> "Dimecres, 12 d’Abril" (or "…D’abril"?)
"%A, %d %^#B" -> "Dimecres, 12 d’abril" (this is probably correct)
This would make this bug report obsolete.
I proposed this idea here:
https://sourceware.org/ml/libc-alpha/2016-12/msg00303.html but it seems to me
it wasn't liked.

resolv: Support an exactly sized buffer in ns_name_pack [BZ #21359]
This bug did not affect name resolution because those functions
indirectly call ns_name_pack with a buffer which is always larger
than the generated query packet, even in the case of the
longest-possible domain name.

resolv: Remove EDNS fallback [BZ #21369]
EDNS is disabled by default (so there is interoperability issue), and
the fallback code is problematic because it prevents an application
from obtaining DNSSEC data after a FORMERR response.

Bug ID: 21383
Summary: HTML format of license in manual has sections
misnumbered but refers to sections by number
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: manual
Assignee: unassigned at sourceware dot org
Reporter: ambrus at math dot bme.hu
CC: mtk.manpages at gmail dot com, roland at gnu dot org
Target Milestone: ---
The GNU libc manual contains a copy of the GNU Lesser General Public License
version 2.1 in "manual/lgpl-2.1.texi". When this is HTML-formatted, such as
displayed in
"http://www.gnu.org/software/libc/manual/html_node/Copying.html#Copying", the
sections are numbered wrong: what is originally section 6 of the Terms and
Conditions is displayed as section 7, and what is originally subsection 6a is
displayed as 7.1. This is a big problem, because the text of the license
refers to those sections by their original number, so the meaning of the
license is unclear.

That looks like a bug in texinfo >= 6, which fails to emit the type and start
attributes of the <ol> element.

--- Comment #2 from Zsban Ambrus <ambrus at math dot bme.hu> ---
And it affects texinfo's own manual rendered as HTML too, at
"http://www.gnu.org/software/texinfo/manual/texinfo/html_node/GNU-Free-Documentation-License.html#GNU-Free-Documentation-License".
I'll report the bug to them then, thank you. Still, it's a bit worrying,
because even if the bug is in texinfo, now it looks as if you were distributing
libc under an invalid license.

--- Comment #2 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
I suggest reopening this bug instead of filing a similar one which I was going
to do.
As suggested in this bug report:
https://bugzilla.gnome.org/show_bug.cgi?id=768192 there is a broader need for
another way to format the day of the month. I hesitate to use the word
"alternative" because someone might say that the alternative format specifiers
already exist, for example "%Od" (this is for alternative digits, for example
Roman or Eastern Arabic, also alternative digits are for all numeric outputs,
not just days) or "%Ed" (unsupported, I'm not sure what would it mean). The
output would be:
- the ordinal day number as required in English (1st, 2nd, …) or Friulian (1â¿,
2, 3,…) or maybe in more languages,
- optionally preceded by a required preposition (Friulian: al 1â¿, ai 2, ai 3…),
- or anything else, as required by specific locales.
Other languages would output a regular decimal number, or would rather not use
this new format specifier.
Browsing the stftime(3) man page I can see that the nearest unused format
specifier is "%f". So, for example:
- "%B %f" would output "April 14th" (or "April 1st") in English;
- "%f di %B" would output "ai 14 di Avrîl (or "al 1⿠di Avrîl) in Friulian.
A similar solution is here: https://github.com/samsonjs/strftime and it
introduces "%o" but says explicitly that it outputs ordinal numbers (while here
I say it can be ordinal or anything else, as required by a specific language)
and it is implemented for English only.

Thank you, Pravin!

Still it's better to be reviewed by a native speaker or at least a person being
able to read the script because even CLDR may be incorrect or a native person
may say "this is correct but not in our context" or "this is correct but you
should also update abbreviated month names" or "this is correct but now date
formats must be corrected" or "the import script failed to convert one
character".

I used the script written by Mike Frysinger:
https://sourceware.org/ml/libc-alpha/2016-02/msg00214.html I needed it for
another bug but since I've processed the month names in all languages and 55
turned out to require the update I decided to post the results online rather
than delete because they are not useful for me. It does not mean the update is
complete because I processed only full month names, nothing else. Other fields
may need update, too.

“Fixed†in 2.25 by the PID cache removal in commit
c579f48edba88380635ab98cb612030e3ed8691e.
Historically, we have not treated such issues as glibc bugs. I'm considering
backporting the PID cache removal.

Target Milestone: ---
The open_memstream() function assigns the address of malloc and free to the
new_f->fp._sf._s._allocate_buffer and new_f->fp._sf._s._free_buffer variables.
This is the actual location of malloc and free not the looked up by the dynamic
linker address of malloc and free. This means that memstream will not use the
malloc hook when allocating memory. This is not ideal but usually works.
The _IO_mem_finish() function in memstream.c uses calls realloc(). This call
goes to the realloc hook. The call to realloc may free memory allocated by the
allocator assigned in open_memstream(). This will trigger an assert because the
malloc hook was not run on the memory that the realloc hook is freeing using
the free hook.
For what ever it is worth I am running on ubuntu 16.04 LTS
I am not sure but I think this is a problem for any user that tries to override
malloc and free.

Could you please provide a minimal example program and show how you link it? I
don't see how this can happen with the upstream memstream implementation.

Thank you for your quick reply.
My first attempt at a simple program is unable to reproduce the issue. I am
unfamiliar with linking issues so it may take a little while to provide the
information you need.
Thanks
Paul Curtis

Florian,
With further investigation I discovered that mcheck() was not as thread safe
as I thought. This appears to be expected behavior. I am sorry that I wasted
your time. Do I close the bug or do you?
Thanks
Paul

Yes, mcheck is unfortunately totally non-thread-safe.

No problem. Thanks for reporting back.

Bug ID: 21390
Summary: robust pthread_mutex_t deadlock from 2.24 -> 2.25
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: thealexozer at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Apparently, when accessing a pthread_mutex_t with the "robust" attribute set
from different threads of different processes, eventually it deadlocks
completely. See
http://stackoverflow.com/questions/42899892/pthread-mutex-t-deadlock-after-package-update
for detailed reproducability details.

[BZ 21357] unwind-dw2-fde: Call free() outside of unwind mutex
__deregister_frame_info_bases() calls free() while holding a mutex which
is also used from _Unwind_Find_FDE(). This leads to a deadlock if
AddressSanitizer uses _Unwind_Backtrace() from its free()
implementation.
Checked on mips-linux-gnu and x86_64-linux-gnu.
[BZ #21357]
* sysdeps/generic/unwind-dw2-fde.c (__deregister_frame_info_bases):
Call free() outside of mutex.

Bug ID: 21391
Summary: x86: Set dl_platform and dl_hwcap from CPU features
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
Target: i386, x86_64
dl_platform and dl_hwcap are set from AT_PLATFORM and AT_HWCAP very
early during startup. They are used by dynamic linker to determine
platform and build an array of hardware capability names, which are
added to search path when loading shared object. dl_platform and
dl_hwcap are unused on x86-64. On i386, i386, i486, i586 and i686
platforms were supported and only SSE2 capability was used.
On x86, usage of AT_PLATFORM and AT_HWCAP to determine platform and
processor capabilities is obsolete since all information is available
in dl_x86_cpu_features. Since i386 has been deprecated, i486 is no
longer needed.

Status: NEW
Severity: normal

Component: stdio
Assignee: unassigned at sourceware dot org

Target Milestone: ---
The code has this:
__dup3 (_IO_fileno (result), fd,
(result->_flags2 & _IO_FLAGS2_CLOEXEC) != 0
? O_CLOEXEC : 0);
That is, there is no error checking for dup3 failure. We should add error
checking here.

--- Comment #2 from Pravin S <pravin.d.s at gmail dot com> ---
Verified patch, it applies clean. Giving expected results.
Thank you Santhosh for this patch.
Atomic Chillu U+0D7A-U+0D7F are in Unicode from 5.1 version and it is important
to have sorting support for this in Glibc.

This could cause security issues if a critical descriptor leaks to child

Bug ID: 21396
Summary: Use AVX2 memcpy/memset on Skylake server
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Target: x86-64
On Skylake server, AVX512 load/store instructions in memcpy/memset may
lead to lower CPU turbo frequency in certain situations. Use of AVX2
in memcpy/memset has been observed to have improved overall performance
in many workloads due to the higher frequency.

--- Comment #1 from Torvald Riegel <triegel at redhat dot com> ---
I think we need a reproducer. The stackoverflow problem description is
incomplete and it mentions that this is timing-dependent (eg, adding logging to
the application seems to prevent the problem); however, the description of the
problem makes it sounds as if just a deterministic access by more than one
thread by the same process would cause the problem to appear (which seems
unlikely).
There were changes in the robust mutex code in the 2.25 release, but all those
were fixing bugs in the robust mutexes. We could have introduced other errors
when doing that, or the code simply runs into the robust mutex bugs that are
still present in the kernel. Without a reproducer, we can't investigate this
further.

x86: Use AVX2 memcpy/memset on Skylake server [BZ #21396]
On Skylake server, AVX512 load/store instructions in memcpy/memset may
lead to lower CPU turbo frequency in certain situations. Use of AVX2
in memcpy/memset has been observed to have improved overall performance
in many workloads due to the higher frequency.
Since AVX512ER is unique to Xeon Phi, this patch sets Prefer_No_AVX512
if AVX512ER isn't available so that AVX2 versions of memcpy/memset are
used on Skylake server.
[BZ #21396]
* sysdeps/x86/cpu-features.c (init_cpu_features): Set
Prefer_No_AVX512 if AVX512ER isn't available.
* sysdeps/x86/cpu-features.h (bit_arch_Prefer_No_AVX512): New.
(index_arch_Prefer_No_AVX512): Likewise.
* sysdeps/x86_64/multiarch/memcpy.S (__new_memcpy): Don't use
AVX512 version if Prefer_No_AVX512 is set.
* sysdeps/x86_64/multiarch/memcpy_chk.S (__memcpy_chk):
Likewise.
* sysdeps/x86_64/multiarch/memmove.S (__libc_memmove): Likewise.

Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Apr 18 21:22:51 2017 +0000
Fix bits/socket.h IOC* namespace issues (bug 21267).
sysdeps/unix/sysv/linux/bits/socket.h includes asm/socket.h. That
includes asm/sockios.h, which on MIPS includes asm/ioctl.h, resulting
in namespace violations from IOC* macros.
bits/socket.h already has code to handle asm/socket.h unconditionally
defining macros that are only wanted for __USE_MISC. This patch
extends it to handle the IOC* macros as well (always undefining them
if not defined when bits/socket.h was included, as I don't think they
are part of the intended API even for __USE_MISC).
It's possible there should also be a kernel fix - it's not clear to me
that IOC* belong in the uapi headers, and even if they do they might
best be split out into another header to avoid getting defined by this
particular path. But since glibc needs to deal with existing kernel
headers, it also seems appropriate to extend the existing workaround
to these macros.
Tested (compilation only) with build-many-glibcs.py.
[BZ #21267]
* sysdeps/unix/sysv/linux/bits/socket.h (IOCSIZE_MASK): Undefine
if defined by <asm/socket.h> and not previously defined.
(IOCSIZE_SHIFT): Likewise.
(IOC_IN): Likewise.
(IOC_INOUT): Likewise.
(IOC_OUT): Likewise.

Bug ID: 21398
Summary: freopen does not check dup3 return value, and does not
return error if dup3 fails (seen when open returns fd
0, and freopen on stdin)
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: olson at cumulusnetworks dot com
Target Milestone: ---
When fd 0 is closed, and the fopen in freopen gets fd 0, and dup3 is available,
the dup3(0,0,0) correctly fails with EINVAL, the return status is ignored, and
fd 0 is closed. Subsequent attempts to use stdin fail.
This was observed in debian jessie with glibc 2.19, but by code inspection on
glibc top of trunk in git, the bug is still present.
Here is a simple test program to show the problem:
#include <stdio.h>
#include <unistd.h>
int main(int cnt, char **args)
{
FILE *newf;
char buf[128], *ret;
if(cnt != 2) {
fprintf(stderr, "Usage: %s filename_to_freopen\n", *args);
return 1;
}
(void)close(0);
newf = freopen(args[1], "r", stdin);
fprintf(stdout, "freopen(%s, r, stdin) returns %p\n", args[1], newf);
fflush(stdout);
fprintf(stdout, "ferror(%p) returns %d\n", args[1], ferror(newf));
ret = fgets(buf, sizeof buf, stdin);
fprintf(stdout, "fgets(%p) returns %p\n", newf, ret);
fprintf(stdout, "2nd ferror(%p) returns %d\n", args[1], ferror(newf));
return 0;
}
With gcc 4.9, it compiles -Wall with no warnings (on a 64bit x86_64 system, but
by inspection, the 32 bit freopen.c has the same bug):
Running it on an existing file (the source for the above program):
./fbug freopen_bug.c
freopen(freopen_bug.c, r, stdin) returns 0x7f0fdada14e0
ferror(0x7ffdaa94ad1a) returns 0
fgets(0x7f0fdada14e0) returns (nil)
2nd ferror(0x7ffdaa94ad1a) returns 1
And strace shows the issue:
16:10:40 close(0) = 0
16:10:40 open("freopen_bug.c", O_RDONLY) = 0
16:10:40 dup3(0, 0, 0) = -1 EINVAL (Invalid argument)
16:10:40 close(0) = 0
(no other system calls in between)

I don't think using a stream where the underlying file descriptor is closed has
defined behviour.

This conflicts with previous guidance I got. Applications are supposed to be
able to close descriptors used by the library (which is why we can't keep open
a descriptor for /dev/urandom, for example). Given this, it appears to be
reasonable to expect that it is possible to resurrect a stream using freopen if
its underlying descriptor has been closed.

In the (non-normative) application usage of close POSIX says: "Usage of close()
on file descriptors STDIN_FILENO, STDOUT_FILENO, or STDERR_FILENO should
immediately be followed by an operation to reopen these file descriptors."

But this doesn't say whether you can use freopen for that purpose.

Version: 2.25
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org

Target Milestone: ---
Created attachment 9998

In file localedata/charmaps/CP1254 at line 238, U+00EC is described as
"LATIN SMALL LETTER E WITH GRAVE" (as is U+00E8 a few lines prior).
U+00EC is actually "LATIN SMALL LETTER I WITH GRAVE".

freopen operates on streams, not file descriptors.

Bug ID: 21400
Summary: Section "Infinity and NaN" of the libc manual
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: manual
Assignee: unassigned at sourceware dot org
Reporter: vincent-srcware at vinc17 dot net
CC: mtk.manpages at gmail dot com, roland at gnu dot org
Target Milestone: ---
https://www.gnu.org/savannah-checkouts/gnu/libc/manual/html_node/Infinity-and-NaN.html
has several issues:
1. This page contains XML/HTML entities (this issue might come conversion to
HTML).
2. "NaN, on the other hand, infects any calculation that involves it. Unless
the calculation would produce the same result no matter what real value
replaced NaN, the result is NaN."
I would replace "any calculation that involves it" by "most calculations that
involve it". The second sentence is also not valid for
fmin/fminf/fminl/fmax/fmaxf/fmaxl when the NaN is a quiet NaN. For instance,
fmin(1,qNaN) will give 1 even though fmin(1,0) would give 0.
3. math.h and fenv.h should respectively be replaced by <math.h> and <fenv.h>
(see the C standard).
4. For the macro NAN, this is no longer a GNU extension. Like INFINITY, it has
been introduced in ISO C99. So, the following parts of the text are no longer
valid: "This macro is a GNU extension" and "(Of course, you must arrange for
GNU extensions to be visible, such as by defining _GNU_SOURCE, and then you
must include math.h.)".
5. "IEEE 754 also allows for another unusual value: negative zero. This value
is produced when you divide a positive number by negative infinity, or when a
negative result is smaller than the limits of representation."
A negative zero can also simply be produced by negating an expression whose
result is a positive zero. So, it is not that unusual. This paragraph may also
not have its place in this section on infinity and NaN. Either the user knows
the existence of the negative zero and this paragraph is useless, or the user
doesn't know it and may be confused (e.g. about -0.0 == +0.0).
Note: There is currently an issue discussed in the stds-754 list about the
non-associativity of the minimum and maximum operations (fmin/fmax/... in C)
with signaling NaN's: fmin(1,fmin(1,sNaN)) → 1 but fmin(fmin(1,1),sNaN) → qNaN,
which is regarded as a mistake in the specification. So, things might change
about TS 18661-1:2014.

--- Comment #6 from Dave Olson <olson at cumulusnetworks dot com> ---
It's not trying to use a stream where the underlying fd is closed, it's trying
to create stdin.
Think of processes that are exec'ed without fd 0 open (which is the real test
case, because it's marked close on exec).
What it's trying to do is to establish a stdin for use with functions that
expect to use stdin.
Even if you don't accept that as a valid use case (and I can accept the
argument, even though I don't agree with it), freopen() should be returning an
error, which means it needs to check for dup3 returning errors.
Right now, freopen in this situation returns what appears to be a valid FILE *,
but the requested action on stdin will fail.
So the minimum is to check for dup3() errors, and then return an error from
freopen().

Note that the full IEEE 754 semantics of fmin/fmax, including that sNaN
maps to qNaN but qNaN arguments are ignored, are implemented in hardware
on AArch64 at least (that is, the present functions can be implemented by
a single instruction on AArch64).

Hi guys,
I'm porting a patch about this problem to newest glibc. I am afraid this bug
were probably more serious than discussed here.
In short, glibc just do not free any memory in the main heap when it become
discoutinuous. As a result, a process may keep the peak physical memory usage
as long as it is alive. This is really bad as glibc are widely used in server
programs...
This bug is not about fragmentation, but more serious. Once all memory are
freed, fragmentation will disappear and all memory could be reused again. But
if the bug occurred, no memory could be reused(by other processes) even all of
them were freed.
In fact, fix to this bug is quite straightforward. Just port the mechanism
used by sub heaps to the main arena should be enough. We have made such a
patch several years ago, and have applied it on production environments since
then. I'll post the patch later after I port it to the new glibc release.

--- Comment #1 from Arjun Shankar <arjun.is at lostca dot se> ---
This smaller example reproduces it for me:
#define _XOPEN_SOURCE 700
#define _POSIX_C_SOURCE 200112L
#include <sys/stat.h>
However, even smaller examples:
#define _XOPEN_SOURCE 700
#include <sys/stat.h>
OR
#define _POSIX_C_SOURCE 200112L
#include <sys/stat.h>
OR
#include <sys/stat.h>
- work fine.
I see that line ~36 of sys/stat.h includes time.h (which may or may not define
'struct timespec' based on enabled features). Later on, bits/stat.h defines
'struct stat' using 'struct timespec' __USE_XOPEN2K8 is defined, and without
using it if it isn't. The mismatch between the conditions that lead to 'struct
timespec' being defined, and the conditions that lead to it being used in the
definition of 'struct stat' - is what causes this error.

Please reopen if you can share a test case that demonstrates that memory is not
reclaimed if it has been fully freed.

--- Comment #14 from Julita Inca Chiroque <jinca at pucp dot pe> ---
Hello, I am from Peru and we usually say Setiembre. Septiembre is also
acceptable but I suggest to use Setiembre with its abbreviation Set.
I think is OK this comment:
+* locales/es_PE (mon, abmon): Reworded "septiembre" to "setiembre"
+and abbreviated "sep" to "set".
Finally this is a Website from the official government of Peru that shows
statistics of the weather and the abbreviation for Setiembre is SET:

--- Comment #2 from Vincent Lefèvre <vincent-srcware at vinc17 dot net> ---
(In reply to joseph@codesourcery.com from comment #1)
> Note that the full IEEE 754 semantics of fmin/fmax, including that sNaN
> maps to qNaN but qNaN arguments are ignored, are implemented in hardware
> on AArch64 at least (that is, the present functions can be implemented by
> a single instruction on AArch64).
https://www.gnu.org/savannah-checkouts/gnu/libc/manual/html_node/Infinity-and-NaN.html
says about the macro FE_SNANS_ALWAYS_SIGNAL:
"This macro, defined by TS 18661-1:2014, is defined to 1 in fenv.h to indicate
that functions and operations with signaling NaN inputs and floating-point
results always raise the invalid exception and return a quiet NaN, even in
cases (such as fmax, hypot and pow) where a quiet NaN input can produce a
non-NaN result."
So, if the hardware behaves differently, it should be noted.

x86-64: Improve branch predication in _dl_runtime_resolve_avx512_opt [BZ
#21258]
On Skylake server, _dl_runtime_resolve_avx512_opt is used to preserve
the first 8 vector registers. The code layout is
if only %xmm0 - %xmm7 registers are used
preserve %xmm0 - %xmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %zmm0 - %zmm7 registers
Branch predication always executes the fallthrough code path to preserve
%zmm0 - %zmm7 registers speculatively, even though only %xmm0 - %xmm7
registers are used. This leads to lower CPU frequency on Skylake
server. This patch changes the fallthrough code path to preserve
%xmm0 - %xmm7 registers instead:
if whole %zmm0 - %zmm7 registers are used
preserve %zmm0 - %zmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %xmm0 - %xmm7 registers
Tested on Skylake server.
[BZ #21258]
* sysdeps/x86_64/dl-trampoline.S (_dl_runtime_resolve_opt):
Define only if _dl_runtime_resolve is defined to
_dl_runtime_resolve_sse_vex.
* sysdeps/x86_64/dl-trampoline.h (_dl_runtime_resolve_opt):
Fallthrough to _dl_runtime_resolve_sse_vex.

X86-64: Add _dl_runtime_resolve_avx[512]_{opt|slow} [BZ #20508]
There is transition penalty when SSE instructions are mixed with 256-bit
AVX or 512-bit AVX512 load instructions. Since _dl_runtime_resolve_avx
and _dl_runtime_profile_avx512 save/restore 256-bit YMM/512-bit ZMM
registers, there is transition penalty when SSE instructions are used
with lazy binding on AVX and AVX512 processors.
To avoid SSE transition penalty, if only the lower 128 bits of the first
8 vector registers are non-zero, we can preserve %xmm0 - %xmm7 registers
with the zero upper bits.
For AVX and AVX512 processors which support XGETBV with ECX == 1, we can
use XGETBV with ECX == 1 to check if the upper 128 bits of YMM registers
or the upper 256 bits of ZMM registers are zero. We can restore only the
non-zero portion of vector registers with AVX/AVX512 load instructions
which will zero-extend upper bits of vector registers.
This patch adds _dl_runtime_resolve_sse_vex which saves and restores
XMM registers with 128-bit AVX store/load instructions. It is used to
preserve YMM/ZMM registers when only the lower 128 bits are non-zero.
_dl_runtime_resolve_avx_opt and _dl_runtime_resolve_avx512_opt are added
and used on AVX/AVX512 processors supporting XGETBV with ECX == 1 so
that we store and load only the non-zero portion of vector registers.
This avoids SSE transition penalty caused by _dl_runtime_resolve_avx and
_dl_runtime_profile_avx512 when only the lower 128 bits of vector
registers are used.
_dl_runtime_resolve_avx_slow is added and used for AVX processors which
don't support XGETBV with ECX == 1. Since there is no SSE transition
penalty on AVX512 processors which don't support XGETBV with ECX == 1,
_dl_runtime_resolve_avx512_slow isn't provided.
[BZ #20495]
[BZ #20508]
* sysdeps/x86/cpu-features.c (init_cpu_features): For Intel
processors, set Use_dl_runtime_resolve_slow and set
Use_dl_runtime_resolve_opt if XGETBV suports ECX == 1.
* sysdeps/x86/cpu-features.h (bit_Use_dl_runtime_resolve_opt):
New.

if Use_dl_runtime_resolve_opt is set. Use
_dl_runtime_resolve_slow if Use_dl_runtime_resolve_slow is set.
* sysdeps/x86_64/dl-trampoline.S: Include <cpu-features.h>.
(_dl_runtime_resolve_opt): New. Defined for AVX and AVX512.
(_dl_runtime_resolve): Add one for _dl_runtime_resolve_sse_vex.

New.

x86-64: Improve branch predication in _dl_runtime_resolve_avx512_opt [BZ
#21258]
On Skylake server, _dl_runtime_resolve_avx512_opt is used to preserve
the first 8 vector registers. The code layout is
if only %xmm0 - %xmm7 registers are used
preserve %xmm0 - %xmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %zmm0 - %zmm7 registers
Branch predication always executes the fallthrough code path to preserve
%zmm0 - %zmm7 registers speculatively, even though only %xmm0 - %xmm7
registers are used. This leads to lower CPU frequency on Skylake
server. This patch changes the fallthrough code path to preserve
%xmm0 - %xmm7 registers instead:
if whole %zmm0 - %zmm7 registers are used
preserve %zmm0 - %zmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %xmm0 - %xmm7 registers
Tested on Skylake server.
[BZ #21258]
* sysdeps/x86_64/dl-trampoline.S (_dl_runtime_resolve_opt):

_dl_runtime_resolve_sse_vex.

X86-64: Add _dl_runtime_resolve_avx[512]_{opt|slow} [BZ #20508]
There is transition penalty when SSE instructions are mixed with 256-bit
AVX or 512-bit AVX512 load instructions. Since _dl_runtime_resolve_avx
and _dl_runtime_profile_avx512 save/restore 256-bit YMM/512-bit ZMM
registers, there is transition penalty when SSE instructions are used
with lazy binding on AVX and AVX512 processors.
To avoid SSE transition penalty, if only the lower 128 bits of the first
8 vector registers are non-zero, we can preserve %xmm0 - %xmm7 registers
with the zero upper bits.
For AVX and AVX512 processors which support XGETBV with ECX == 1, we can
use XGETBV with ECX == 1 to check if the upper 128 bits of YMM registers
or the upper 256 bits of ZMM registers are zero. We can restore only the
non-zero portion of vector registers with AVX/AVX512 load instructions
which will zero-extend upper bits of vector registers.
This patch adds _dl_runtime_resolve_sse_vex which saves and restores
XMM registers with 128-bit AVX store/load instructions. It is used to
preserve YMM/ZMM registers when only the lower 128 bits are non-zero.
_dl_runtime_resolve_avx_opt and _dl_runtime_resolve_avx512_opt are added
and used on AVX/AVX512 processors supporting XGETBV with ECX == 1 so
that we store and load only the non-zero portion of vector registers.
This avoids SSE transition penalty caused by _dl_runtime_resolve_avx and
_dl_runtime_profile_avx512 when only the lower 128 bits of vector
registers are used.
_dl_runtime_resolve_avx_slow is added and used for AVX processors which
don't support XGETBV with ECX == 1. Since there is no SSE transition
penalty on AVX512 processors which don't support XGETBV with ECX == 1,
_dl_runtime_resolve_avx512_slow isn't provided.

The hardware behaves as described there. My point is that you seemed to
be suggesting some change in semantics from the current IEEE 754 / TS
18661 semantics that can be implemented with a single hardware instruction
on current hardware, to some other semantics that would be less efficient.

Fix missing timespec definition for sys/stat.h (BZ #21371)
As indicated by the bug report, the 'struct timespec' definition
is not defined for '_XOPEN_SOURCE=700' and '_POSIX_C_SOURCE=200112L'.
It is because current code only includes its definition if __USE_ATFILE
is defined and the define is only set with:
1. _GNU_SOURCE and/or _ATFILE_SOURCE definition.
2. _POSIX_C_SOURCE >= 200809L
However, the 'st_*' fields in 'struct stat' are defined if __USE_XOPEN2K8.
This patch uses the same logic for 'struct timespec' inclusion.
Tested on x86_64-linux-gnu.
* io/sys/stat.h: Use __USE_XOPEN2K8 insteaf of __USE_ATFILE for
struct timespec definition.

test_case to show the peak memory usage retain after memory all freed
Hi all,
I have post a test to show the most dangerous impact of the bug(please make
sure you have more than 4G memory). In short, a process may keep the peak
physical memory usage when the bug occurred.
Imagine there were three daemon servers on a 8G-memory machine, the three
guys work for on same data pipeline to provide useful information. Assume each
of them use up to 4G memory, we know they will run happily as they were
designed to work serially. However, if this bug occurred unfortunately , one
of the three could not get enough memory, which lead to OOM or unacceptably
slow swap usage.

--- Comment #3 from fios at foramnagaidhlig dot net ---
This fix is also needed for my locale (Scottish Gaelic) and would follow the
same pattern as English:
1 = 1d
2 = 2na
3 = 3s
Note that the CLDR does not support coding this either, so the CLDR data isn't
100% reliable here.

Summary: realloc documentation error
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: seahen123 at gmail dot com
Target Milestone: ---
Lines 517-519 in malloc/malloc.c appear to be inaccurate: in lines 3031-3032,
realloc does nothing to an mmapped chunk if the new size fits in the existing
allocation -- even if pages could otherwise be freed. This is probably worth
mentioning, because programs in low-memory environments may have to work around
it by doing a malloc-copy-free themselves.

Any chance we can get Argon2 support for crypt in glibc? If we get it, we
probably won't need PBKDF2 (which is better than sha512crypt) or bcrypt.

I'd create a patch myself if I knew how.

Bug ID: 21422
Summary: Deadlock in 2.25 pthread_cond_broadcast after process
abort
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: michael.krasnyk at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 10015
--> https://sourceware.org/bugzilla/attachment.cgi?id=10015&action=edit
Test for reproduction
Hi, in glibc 2.25 the attached test hangs in pthread_cond_broadcast. The test
code creates a shared mmapped file /tmp/test.mmap with a shared mutex and a
conditional variable. If the waiting process was aborted and restarted, the
signaling process hangs in pthread_cond_broadcast.
Correct behavior:
./a.out 1
./a.out 2 & ( sleep 1 ; ./a.out 3 )
Hangs on the third line in "./a.out 3" process with libc 2.25, but works with
2.24:
./a.out 1
./a.out 2 & p=$! ; ( sleep 1 ; kill -SIGABRT $p ; ./a.out 3 )
./a.out 2 & ( sleep 1 ; ./a.out 3 )

Not all hardware. On Cadence® Tensilica® Fusion G3, min or max of (1,sNaN)
gives 1 instead of qNaN, as noted in David H.C. Chen's report. But perhaps it
is not supported by glibc...

No, it seems that minNum, etc. will probably be removed from IEEE 754 and new
operations added. So, the best way for TS 18661 would be to drop fmin/fmax spec
concerning sNaN (i.e. leave it undefined), at least until things get clearer on
the IEEE 754 side.

I'm referring specifically to AArch64 hardware as a case implementing the
existing semantics in a single instruction (and which thus did not require
any glibc changes to its fmin/fmax implementations to implement TS 18661-1
semantics). (And I did test on hardware as well as checking the
architecture specification.)
POSIX has also had TS 18661-1-style requirements for sNaNs for a long
time: "On implementations that support the IEC 60559:1989 standard
floating point, functions with signaling NaN argument(s) shall be treated
as if the function were called with an argument that is a required domain
error and shall return a quiet NaN result, except where stated otherwise.
Note: The function might never see the signaling NaN, since it might
trigger when the arguments are evaluated during the function call.".
(Although that fails to deal with the various cases where IEEE 754
explicitly says exceptions do not occur for sNaN arguments, and is
ambiguous about what counts as stated otherwise; 18661-1 seems a
better-thought-out version of such semantics.)
Non-associativity would presumably apply equally to hypot:
hypot(sNaN,hypot(qNaN,Inf)) is qNaN but hypot(hypot(sNaN,qNaN),Inf) is
Inf. Of course the IEEE 754 hypot operation (corrected rounded) isn't
strictly associative for finite arguments anyway. FWIW, C++17 has a
three-argument hypot function, but doesn't specify how infinities and NaNs
are handled by it.

In any case, Inf is a correct answer. I suppose that for min/max, one may
consider that sNaN does not mean "missing data", and a non-NaN result could be
regarded as incorrect after the second call. Moreover, AFAIK, the
non-associativity of min/max is an issue mainly for those who wanted to
implement a min/max reduction operation by a sequence of 2-ary min/max in the
context of parallelism and wanted reproducibility. But as you say, hypot is
already not associative for finite arguments (so that results would not be
reproducible).

--- Comment #1 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
Hi,
I'm following the nptl bugs since we found some apparent ones ourselves in
2.25.
I looked at your code and it could be you are depending on undefined behaviour.
When you abort and restart the process, shouldn't you use a robust mutex? Can
you try that?
http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_mutexattr_setrobust.html
and check if the calls set errno values to EOWNERDEAD or ENOTRECOVERABLE.
cheers,
Dimitri

--- Comment #2 from Michael Krasnyk <michael.krasnyk at gmail dot com> ---
Hi Dimitri,
i have tried the same test with additional line
pthread_mutexattr_setrobust(&m_attr, PTHREAD_MUTEX_ROBUST);
but the results is the same. The aborted process waits not in
pthread_mutex_lock
but in pthread_cond_wait, so the mutex is not locked by the process.
Also the hang occurs not in waiting for a signal, but in sending one by
pthread_cond_signal or pthread_cond_broadcast.
Regards,
Michael

--- Comment #3 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
Hi Michael,
thanks for trying. Just wanted get that angle covered.
I can confirm I'm seeing the same behaviour on my system. It works in 2.24 and
on 2.25 the sending process hangs in pthread_cond_wait. However, when compiling
a debug build (gcc -g3 -lpthread test.c -o test), it did work. Does a debug
build work on your end as well?
I hope the devs can do something with this.
Thanks for flagging this, so we know we don't have to look for bugs in our code
when we see this one pop up.
cheers,
Dimitri

--- Comment #4 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
It has nothing to do with the debug build. It just doesn't happen always. I'm
not sure it has anything to do with the SIGABRT either. The
pthread_cond_broadcast just seems to hang randomly.
This is some gdb output:

/usr/lib/libpthread.so.0

I think the intended comment is "*if* remapping is required, *then* a
map-copy-unmap is used, unless the needed remapping can be done with MREMAP"
I don't think the intent was to say that a remap is always forced.

Still, because of the case where realloc could free entire pages and doesn't,
there should be an indication in the doc comments that realloc will *never*
free pages when the source region has been mmap'd, the target size is nonzero,
and Linux mremap is not available. (FreeBSD has mremap, but in a different and
incompatible form, and if I understand correctly, using it would mean
implementing glibc *on top of* FreeBSD libc.)

--- Comment #5 from Torvald Riegel <triegel at redhat dot com> ---
In general, if you kill processes that may be executing blocking
synchronization, then this may block other processes that the former processes
where synchronizing with. For example, non-robust mutexes are blocking
synchronization; if you happen to kill a process that has acquired a lock, no
other process can subsequently acquire the lock. Robust mutexes work around
that by employing something like a failure detector.
Non-blocking synchronization mechanisms such as C11 atomics that are lock-free
do continue to work if one of the processes stops, or is killed. (However,
please treat this statement as just an illustrating example; killing a C11
process is kind of a grey zone regarding the standard's forward progress
requirements.)
Condition variables are not required to perform non-blocking synchronization
only. POSIX (and glibc) do not specify (or provide) robust variants of
condition variables either. Therefore, this is not a bug.
I don't know what you want to do, but one approach would be to catch signals
and use POSIX' cancellation to cancel the pthread_cond_wait; another option
might to use nonblocking synchronization such as C11 atomics.

--- Comment #6 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
Hi Torvald,
thank you for the insights. I have a question, though:
POSIX does define pthread_cond_wait() as a cancellation point. So, if the
calling thread is cancelled, shouldn't the condition variable handle this
correctly? I also observe the process sending the pthread_cond_broadcast() lock
up if the process blocking on the condvar was interrupted with SIGINT, and
another process is started, for instance.
I do agree with you that a SIGKILL during the pthread_cond_wait() can result in
undefined behaviour since there are no robust condvars.
thanks again,
Dimitri

If you use pthread_cancel, then yes, it should work. If the thread is
terminated by other means, the condition variable may end up in an inconsistent
state.

What happens due to the SIGINT? Does a futex system call return EINTR or
something like that?

I don't know exactly how SIGINT is implemented on Linux. But I now fully agree
with you, this is not a bug but undefined behaviour.
Thanks for clearing it up for me!
cheers,

Bug ID: 21426
Summary: sys/socket.h uio.h namespace
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
Target Milestone: ---
sys/socket.h include sys/uio.h to get the definition of the iovec structure.
POSIX allows sys/socket.h to make all sys/uio.h symbols visible. However, all
of sys/uio.h is XSI-shaded, so for non-XSI POSIX this results in conformtest
failures (for sys/socket.h and other headers that include it):
Namespace violation: "UIO_MAXIOV"
Namespace violation: "readv"
Namespace violation: "writev"
Now, there is some ambiguity in POSIX about what namespace reservations apply
in this case - see http://austingroupbugs.net/view.php?id=1127 - but glibc
convention would still avoid declaring readv and writev, for example, for
feature test macros that don't include them (if only headers from the relevant
standard are included), even if such declarations are permitted, so there is a
bug here according to glibc conventions.

Thanks for the discussion!
The original issue is https://github.com/Project-OSRM/osrm-backend/issues/3911
Unfortunately shared condition variables may indeed end up in some inconsistent
state and pthread_cancel will not work due to possible OOM SIGKILL signals.
Mainly the report is about clarification if it is an undefined behavior change
from 2.24 to 2.25 or a regression.
Without robust conditional variables it will not be possible to make correct
IPC signaling.
Regards,
Michael

commit 9fe3c80c7c3dbce34dadc7f0693d211fdd9a0b03
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Apr 25 17:52:47 2017 +0000
Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426).
sys/socket.h includes sys/uio.h to get the definition of the iovec
structure.
POSIX allows sys/socket.h to make all sys/uio.h symbols visible.
However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this
results in conformtest failures (for sys/socket.h and other headers
that include it):
Namespace violation: "UIO_MAXIOV"
Namespace violation: "readv"
Namespace violation: "writev"
Now, there is some ambiguity in POSIX about what namespace
reservations apply in this case - see
http://austingroupbugs.net/view.php?id=1127 - but glibc convention
would still avoid declaring readv and writev, for example, for feature
test macros that don't include them (if only headers from the relevant
standard are included), even if such declarations are permitted, so
there is a bug here according to glibc conventions.
This patch moves the struct iovec definition to a new
bits/types/struct_iovec.h header and includes that from sys/socket.h
instead of including the whole of sys/uio.h. This fixes the namespace
issue; however, three files in glibc that were relying on the implicit
inclusion needed to be updated to include sys/uio.h explicitly. So
there is a question of whether sys/socket.h should continue to include
sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or
__USE_XOPEN || __USE_MISC, for greater compatibility with code that
(wrongly) expects this optional inclusion to be present there. (I
think the three affected files in glibc should still have explicit
sys/uio.h inclusions added in any case, however.)
Tested for x86_64.
[BZ #21426]

Also note your specific example is not allowed by POSIX. You cannot serialize
the mutex state to disk and reload it. A glibc upgrade could change the
internal structure of the type and the second run of the application would fail
to be able to correctly use the structure. I've written a blog post about the
problems inherent here when background upgrades are allowed:

If some of the synchronizing process can just be killed, then blocking
synchronization in general will be a problem for you. As I mentioned earlier,
robust mutexes are different, but they had glibc implementation bugs before
glibc 2.25 and still have a bug in current Linux kernels.
If you want to avoid busy waiting when using the atomics, perhaps try combining
them with futexes to build exactly the synchronization mechanism you need. I
don't think that futexes explicitly promise to be nonblocking, but I believe
they are in practice (eg, killing a process that's in a futex-wait call
shouldn't block subsequent futex-wake calls).

I'd like to stress again that this applies to all things do potentially
blocking synchronization (eg, semaphores). How likely you might be in practice
to run into these problems will vary, but you can't really rely on it to not
happen.

You can with nonblocking atomics, but I agree that this is harder.

I use Archlinux, and 32 bits of system.
Have a error of Leak Memory in the dlsym, also dlsym(0,"") and dlsym(hnd,"")
take the two library in the different memory where i use RTLD_NOLOAD.
This is the code of main.cpp with the result of Valgrind:
#include <stdio.h>
#include <stdlib.h>
#include <dlfcn.h>
#include <allegro5/allegro.h>
int main(int argc, char *argv[]){
//void*hnd=dlopen("/usr/lib/liballegro.so",RTLD_NOW|RTLD_GLOBAL|RTLD_NOLOAD);
void*hnd=dlopen("liballegro.so",RTLD_NOW|RTLD_GLOBAL|RTLD_NOLOAD);
//void*hnd=dlopen("/usr/lib/liballegro.so.5.2.2",RTLD_NOW|RTLD_GLOBAL|RTLD_NOLOAD);
printf("HND:%p (DEFAULT:%d)\n",hnd,RTLD_DEFAULT);
if(!hnd){printf("fopen\n");return -1;}
void*p=dlsym(0,"al_translate_transform");
void*p2=dlsym(hnd,"al_translate_transform");
void*p3=dlsym(RTLD_DEFAULT,"al_translate_transform");
printf("Cargado\n");
printf("P:%p P2:%p P3:%p\n",p,p2,p3);
printf("%p\n",al_translate_transform);
dlclose(hnd);
return 0;

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
These are allocation which are handle by loader cache and only shown in
valgrind with the '--show-reachable=yes'. Since they are cached for the
application, it is expected that loader maintains lingering pointers to the
data and I think it should not be handled a *leaked* memory.
You can check that adding a loop in your program (to dlopen/dlsym/dlclose
multiple times) do not increase the cache usage, as expected.

backtrace is missing the name of cancellation point syscalls because of the asm
code layout (function symbol does not cover the part where the syscall is
made), this is planned to be fixed during the cancellation cleanup patch set

This corrupts the arena and the chunk metadata by writing zero (if the kernel
honours the address hint). You can't place a mapping at a fixed address that
may already contain data. You must know that address is empty or you're going
to have serious problems, possibly overwriting whatever is already at that
address.
Corruption of metadata my indeed result in all memory not being freed.

If it does, it's a kernel bug. If the break point overlaps with the mapping,
the mmap call must fail because MAP_FIXED hasn't been specified.
Even without the hint, something like that could happen under virtual address
space pressure.
I think this needs further analysis.

You are absolutely right, I missed that MAP_FIXED wasn't in the flags.

We already support foreign sbrk in the main arena, thus we support
non-contiguous cases.
This looks like one of those such cases, but instead of a foreign sbrk, we have
a foreign mmap.
I'm reopening and looking at it under the debugger to see what really changes
if anything.

--- Comment #9 from Carlos O'Donell <carlos at redhat dot com> ---
Is it really that hard to implement the lookup required to be able to return an
error on a double dlclose()? The standard has required it for a long time, and
it does seem useful in many cases where you might not know the state of a
handle.

Dear all,
We found a null pointer dereference resulting in a segmentation fault, that
might be a bug in diffutils or a bug in GLIBC depending on the perspective one
takes. The patch can be in GLIBC (introducing a simple null pointer check) or
in Diffutils (preventing the null pointer dereference altogether). We already
reported the bug downstream at
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26690. Below we provide a quick
analysis. We think, it is actually an incorrect use of GLIBC. However, since it
can be easily prevented in GLIBC, we thought we should report it here as well.
This bug was found with AFLGo, a directed version of AFL/AFLFast. Thanks also
to Van-Thuan Pham.

SUMMARY: AddressSanitizer: SEGV
/build/eglibc-MjiXCM/eglibc-2.19/posix/regexec.c:414 in re_search_stub
This is our analysis:
For the diff-tool the argument -I<regexp> specifies the changed lines to
exclude. For each such argument, the function add_regexp in diff.c is called.
This function uses re_compile_pattern to successfully compile the first
pattern. However, it fails to compile the second pattern, giving the error
“Trailing backslashâ€. In both cases, the function uses the re_pattern_buffer
*ignore_regexp. However, the failed compilation corrupts *ignore_regexp,
setting ignore_regexp->buffer=0x0 and ignore_regexp->allocated=0. Later, in
function summarize_regexp_list, it is established that at least one pattern was
successfully compiled and ignore_regexp->fastmap is set, indicating that
re_search is being called in utils.c:1501. Unfortunately, it is being called on
the corrupted ignore_regexp where ignore_regexp->buf = 0x0. GLIBC does not
check for a null-pointer when derefencing the buffer in regexec.c:413.

Hi all,
It's happy to see your replies. The mmap in the test code seems confusing,
but we are just trying to make a fence in front of brk(to make the main arena
discoutinuous). This action can be replaced by a normal mmap(which is normal in
user progarms), providing result address of the mmap is in front of brk.
I have ported our local patch to glibc-2.24(and it works as expected :) ).
I'll post it later if you were intereted.

If you are going to post patches please follow the contribution checklist,
particularly the copyright section:
https://sourceware.org/glibc/wiki/Contribution%20checklist
I can confirm that sbrk will fail when it runs across the mmap'd region, and
malloc will fall back to using mmap as MORECORE and set the main_arena as
non-contiguous.
The question which remains is to double check the trimming logic to make sure
it could be capable of undoing that transition to start freeing back to the
original sbrk region.
I don't think it can because this code triggers:
/*
Only proceed if end of memory is where we last set it.
This avoids problems if there were foreign sbrk calls.
*/
current_brk = (char *) (MORECORE (0));
if (current_brk == (char *) (av->top) + top_size)
The discontinuity is as-if a foreign sbrk had been applied, and that means we
won't free any memory.
If mmap's keep intersecting the heap of the main_arena, we will see continued
increases in RSS that we can't free without calling malloc_trim() which trims
not just from the top but from all coalesced chunks everywhere.

--- Comment #14 from Carlos O'Donell <carlos at redhat dot com> ---
Thinking more deeply about this the only way we are going to solve this is by
having main_arena gain a full heap_info, and when sbrk fails, allocate a second
heap with mmap. The heap_info structure is what we need to track and trim
top-of-heap properly. So we will have moved main_arena closer to what the other
arenas are like with the capability to have multiple heaps. Though in the case
of main_arena it would only happen when the traditional heap fails.

So to be clear, this is the kind of patch I'd be looking for if someone were
going to work on a solution for this.
I'm not going to tackle this right now.

--- Comment #11 from Rich Felker <bugdal at aerifal dot cx> ---
It's essentially never useful for the reason the EBADF error from close is
never useful: it can tell you whether the resource identifier was currently
valid at the time of the close call, but not whether it referred to what you
thought it did, or whether it acted on a resource owned by some other part of
the program (or internal to the implementation) that you didn't intend to act
on.
The only reason to implement this behavior at all is for strict standards
conformance.

Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
signal.h declares bsd_signal for __USE_XOPEN. But this function was obsoleted
in the 2001 edition of POSIX and removed in the 2008 edition, so it should not
be declared when the 2008 edition is in use.

x86: Use AVX2 memcpy/memset on Skylake server [BZ #21396]
On Skylake server, AVX512 load/store instructions in memcpy/memset may
lead to lower CPU turbo frequency in certain situations. Use of AVX2
in memcpy/memset has been observed to have improved overall performance
in many workloads due to the higher frequency.
Since AVX512ER is unique to Xeon Phi, this patch sets Prefer_No_AVX512
if AVX512ER isn't available so that AVX2 versions of memcpy/memset are
used on Skylake server.
[BZ #21396]
* sysdeps/x86/cpu-features.c (init_cpu_features): Set
Prefer_No_AVX512 if AVX512ER isn't available.
* sysdeps/x86/cpu-features.h (bit_arch_Prefer_No_AVX512): New.

It is useful in specific cases. It requires that program logic allow you to
make the kind of assertions your claim.
I agree that in general you can't make abstract assertions about ownership of
the handle, but that has it's own problems (infinite memory requirements).

I disagree as stated above. You can use program logic to allow you to make use
of the POSIX behaviour.
Knowing if it was _your_ handle, associated with _your_ dlopen, would be really
really nice to know. And I think we can do that with monotonically increasing
IDs at the expense of ABA on the detection in 32-bit. Though this would only be
a hardening feature of an ID-based implementation, and no worse than what POSIX
requires.

commit c064f6a613844181f411aabb2662384a6aefb69e
Author: Tulio Magno Quites Machado Filho <tuliom@linux.vnet.ibm.com>
Date: Fri Apr 28 19:45:52 2017 -0300
powerpc: Fix logbl on power7 [BZ# 21280]
1. Fix the results for negative subnormals by ignoring the signal when
normalizing the value.
2. Fix the output when the high part is a power of 2 and the low part
is a nonzero number with opposite sign. This fix is based on commit
380bd0fd2418f8988217de950f8b8ff18af0cb2b.
After applying this patch, logbl() tests pass cleanly on POWER >= 7.
Tested on powerpc, powerpc64 and powerpc64le
[BZ #21280]
* sysdeps/powerpc/power7/fpu/s_logbl.c (__logbl): Ignore the
signal of subnormals and adjust the exponent of power of 2 down
when low part has opposite sign.

Can we get this into the 2.25 branch as well?
As it is, 2.25 is completely broken on my Atom CPU, and I don't want to wait
until 2.26.

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Since re_exec is an GNU extension this API corner case should be documented and
afaik unfortunately they aren't (using the gnulib documentation [1]).
For these cases I tend to follow, if possible, the POSIX inspired API. On POSIX
regular expression API [2] states that:
"[...] If the preg argument to regexec() or regfree() is not a compiled regular
expression returned by regcomp(), the result is undefined. [...]"
So if I understood correctly the issue description, it is using an invalid
regular expression buffer description on re_search (since the expression
compilation failed). IMHO we should treat this as undefined (as POSIX
counterpart) and let the user handle it correctly. In a short, I would say we
should close this as not a bug.

--- Comment #2 from Dave Olson <olson at cumulusnetworks dot com> ---
Since you duped my bug to this one, I would request that the severity be
increased. Applications that change for freopen errors end up with extremely
hard to debug problems as a result of this.

--- Comment #4 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
As per comment #2 glibc already provides a way to actually enables it, either
through environment variable or through a GNU extensible API. As a side note,
for GLIBC 2.25+ the way to do it is through the new tunables API [1].
Also, the idea of penalizing performance where suitable API are already
provided without giving the developer a choice on actually not using it does
not sounds appealing to me. Also we have different uninitialized memory tools
besides GLIBC own perturb tunable, such as msan, valgrind, etc (although I give
you that its architecture coverage is less than ideal).
Any how, I am closing this bug not because of the proposal itself, but rather
it cover different things that would require different goals and discussions:
- Add a configure option to enable MALLOC_PERTURB_ as default.
- Specify which kind of operations it would require for _start/_exit (should
it clean only the anonymous mmap pages allocated through malloc or all possible
data segments from bss/tbss/etc.).
- Define which symbol really require such fortification instead of listing a
generic list.
So if you want to follow discussion on such proposal please either start a
discussion on libc-alpha or create a *specific* bug proposal with a narrow
implementation focus (for instance, on fist topic I listed).
Also, you may also want to check on WIP tunables runtime proposal, which the
idea is exactly to give a system wide configuration system. The idea is exactly
to make it possible to setup system wide tunable options.

--- Comment #1 from eggert at cs dot ucla.edu ---
mktime has unpredictable values even when tm_isdst is 0. For example, when
TZ='Europe/Moscow', asking mktime about 2014-10-26 01:30:00 with tm_isdst=0 can
yield either 1414272600 (2014-10-26 01:30:00 +0400) or 1414276200 (2014-10-26
01:30:00 +0300); both time stamps are valid because Moscow changed its standard
time zone that morning.
I suppose mktime could be altered to always return the earliest among ambiguous
dates, or something like that. However, with the current architecture this
would significantly slow down mktime. It'd take quite a bit of hacking to
adjust mktime to be more predictable, and the benefits of such a change do not
clearly outweigh the cost. AFter all, with ambiguous dates, no matter what
mktime does, it'll be "wrong" for some users.

Bug ID: 21455
Summary: Network headers stdint.h namespace
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
Target Milestone: ---
conform/ namespace tests of arpa/inet.h, netdb.h and netinet/in.h fail for
UNIX98 and XPG42 because of inclusion of stdint.h, which defines macros not
permitted in those headers for those standards. UNIX98 allows them to include
inttypes.h, but has restricted inttypes.h contents (not yet tested in the
conform/ tests) not including those macros; XPG4.2 has no such permission and
no inttypes.h / stdint.h at all.

Bug 20686: Add el_GR@euro support.
Despite the fact that el_GR is ISO-8859-7:2003 which contains the euro
symobl, it is not possible to know this apriori to selecting the el_GR
locale. Therefore you don't know if el_GR can possibly have the 2003
ammendments which include the euro symbol. This is resolved by creating
an el_GR@euro locale similar to all the other @euro locales for non-UTF8
charsets.

Tweak realloc/MREMAP comment to be more accurate.
MMap'd memory isn't shrunk without MREMAP, but IIRC this is intentional for
performance reasons. Regardless, this patch tweaks the existing comment to
be more accurate wrt the existing code.

* malloc/malloc.c: Tweak realloc/MREMAP comment to be more accurate.

x86: Set dl_platform and dl_hwcap from CPU features [BZ #21391]
dl_platform and dl_hwcap are set from AT_PLATFORM and AT_HWCAP very
early during startup. They are used by dynamic linker to determine
platform and build an array of hardware capability names, which are
added to search path when loading shared object. dl_platform and
dl_hwcap are unused on x86-64. On i386, i386, i486, i586 and i686
platforms were supported and only SSE2 capability was used.
On x86, usage of AT_PLATFORM and AT_HWCAP to determine platform and
processor capabilities is obsolete since all information is available
in dl_x86_cpu_features. This patch sets dl_platform and dl_hwcap from
dl_x86_cpu_features in dynamic linker. On i386, the available plaforms
are changed to i586 and i686 since i386 has been deprecated. On x86-64,
the available plaforms are haswell, which is for Haswell class processors
with BMI1, BMI2, LZCNT, MOVBE, POPCNT, AVX2 and FMA, and xeon_phi, which
is for Xeon Phi class processors with AVX512F, AVX512CD, AVX512ER and
AVX512PF. A capability, avx512_1, is also added to x86-64 for AVX512
ISAs: AVX512F, AVX512CD, AVX512BW, AVX512DQ and AVX512VL.
[BZ #21391]
* sysdeps/i386/dl-machine.h (dl_platform_init) [IS_IN (rtld)]:
Only call init_cpu_features.
[!IS_IN (rtld)]: Only set GLRO(dl_platform) to NULL if needed.

commit fd9f30f6f9b266405d88eb11b1f8793451629125
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu May 4 11:26:33 2017 +0000
Use __glibc_reserved convention in mcontext, sigcontext (bug 21457).
This patch implements the most straightforward part of fixing
namespace issues for sys/ucontext.h and related headers: where fields
in sys/ucontext.h or bits/sigcontext.h are named "reserved", "padding"
or similar, they are renamed to use the __glibc_reserved* naming
convention. It does not change fields with a leading underscore, or
even those with a prefix such as uc_ or sc_. It only fixes a small
part of bug 21457, so no XFAILs are removed.
Tested for x86_64 and x86, and with build-many-glibcs.py.
[BZ #21457]
* sysdeps/unix/sysv/linux/mips/sys/ucontext.h
[_MIPS_SIM != _ABIO32] (mcontext_t): Rename field reserved to
__glibc_reserved1.
* sysdeps/unix/sysv/linux/x86/bits/sigcontext.h
(struct _fpx_sw_bytes): Rename field padding to __glibc_reserved1.
(struct _fpxreg): Likewise.
[!__x86_64__] (struct _fpstate): Rename field reserved to
__glibc_reserved1. Rename field padding to __glibc_reserved2.
[__x86_64__] (struct _fpstate): Rename field padding to
__glibc_reserved1.
(struct _xsave_hdr): Rename field reserved1 to __glibc_reserved1.
Rename field reserved2 to __glibc_reserved2.
* sysdeps/unix/sysv/linux/x86/sys/ucontext.h
[__x86_64__] (struct _libc_fpxreg): Rename field padding to
__glibc_reserved1.
[__x86_64__] (struct _libc_fpstate): Rename field padding to
__glibc_reserved1.

Fix signal.h bsd_signal namespace (bug 21445).
signal.h declares bsd_signal for __USE_XOPEN. But this function was
obsoleted in the 2001 edition of POSIX and removed in the 2008
edition, so it should not be declared when the 2008 edition is in use.
This patch fixes the conditionals accordingly. (This does not fix any
conform/ test failures because of other namespace issues in signal.h.)
Tested for x86_64.
[BZ #21445]
* signal/signal.h [__USE_XOPEN2K8] (bsd_signal): Do not declare.

commit 176804300be88f9ceaef7d7a2304b1ed48f0f356
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu May 4 20:36:42 2017 +0000
Fix network headers stdint.h namespace (bug 21455).
conform/ namespace tests of arpa/inet.h, netdb.h and netinet/in.h fail
for UNIX98 and XPG42 because of inclusion of stdint.h, which defines
macros not permitted in those headers for those standards. UNIX98
allows them to include inttypes.h, but (predating C99) has restricted
inttypes.h contents (not yet tested in the conform/ tests) not
including those macros; XPG4.2 has no such permission and no
inttypes.h / stdint.h at all.
This patch rearranges the headers to avoid this issue. intN_t
definitions move to bits/stdint-intn.h, and uintN_t definitions to
bits/stdint-uintn.h. (These are not bits/types/ headers because they
each define four types. They are separate rather than just a single
header because sys/types.h defines intN_t but u_intN_t rather than
uintN_t - and while sys/types.h could define uintN_t because of the
POSIX reservation of *_t, existing practice there is largely to
condition types on appropriate feature test macros, and indeed there
is at least one open bug report (14553) about a type that's not
so-conditioned, so maybe types there should actually have conditions
added where appropriate.) The affected network headers are then made
to include bits/stdint-uintn.h instead of stdint.h. This allows six
XFAILs to be removed.
This doesn't do anything about inttypes.h defining more than it should
for UNIX98, but we don't have conformtest expectations for that case
at present (and my inclination is that a fix for that should be as
local as possible - affecting only inttypes.h, not stdint.h, only for
the case of __USE_UNIX98 && !__USE_ISOC99).
Tested for x86_64.

Summary: sunrpc: Memory leak after deserialization failure in
xdr_bytes, xdr_string
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security+
Reported by Marcus Meissner here:
http://openwall.com/lists/oss-security/2017/05/05/1
“
We also saw glibc affected.
https://bugzilla.suse.com/show_bug.cgi?id=1037559#c7
That said, your reproducer allocates virtual memory, and on systems with
overcommit
there is only neglible impact on overall memory pressure.
The rpc service will however likely crash at some point though when there is no
virtual
address space left for it.

--- Comment #15 from Милош Поповић <gpopac at gmail dot com> ---
When updating Serbian, we would prefer to update "sr" locale, since "sr@latin"
is automagically generated from "sr" (thus the changes will be overwritten).
So changes for "sr" would be:

I would also note that firefox uses a jemalloc fork (mozjemalloc) and so
interfaces directly with the OS for memory requests. This allows the browser to
more carefully tailor their memory allocation needs to the allocator, with more
apriori information about the allocation patterns you can usually do better
than a generic allocator.
The Fedora 25 chromium build does appear to use the system memory allocator,
and so would be an interesting candidate for analysis if it is indeed causing
the system to run out of memory.
Java similarly doesn't use glibc's malloc, instead it has it's own garbage
collection and AFAIK uses mmap directly for most of these uses.
So it looks like none of these problems are related to userspace, but instead
might be related to kernel issues around virtual memory utilization.
We need a lot more information which is why this is currently closed
RESOLVED/INVALID.

Chromium/Chrome uses its own tcmalloc fork afaik and I agree with you it does
seems more related to a kernel issues than an userspace one.

--- Comment #6 from dieter ferdinand <dieter.ferdinand at gmx dot de> ---
hello,
i make some tests on my testsystem and use 5 gb with chromium and this system
has 7 gb usable memory and no swap.
on my master server, i make the same test and i get some out of memory messages
and the tool i need reports max 4,5 GB used ram. i restart firefox and it
crashed.
and same other programs to.
this system have 16GB ram and 8 GB swap.
if i try to reserve 5gb memory with memtester i get out of memory and i have
more then 10gb available ram and mor the 7gb free swapspace.
i can't find out why i can use on my masterserver only 25-30% of the physical
ram.
i make the tests on both systems with 64bit kernel 4.9.23 and on the
test-system with a 32bit kernel 3.18.47. i use on both system chromium 32 bit.
i have opened on my master-system many tabs in chromium, exit it and start it
again and it is crashed.
if i open chromium and open many tabs, no problem. but if i start chromium and
it restore the tabs -> out of memory, can't fork -> chromium crash!
only on my testsystem chromium don't crash. but i can make some tests again.
i try to reserve memory with memtester and i can reserve 4,5 GB on my server so
i use a little more as 8 gb. but this is impossible with other applications. i
get always out of memory or resource not available, can't fork. i have less
then 650 processes running. on testsystem less then 250 processes.
but i can't make such tests on my server because it can kill importent
programms.
i make the tests on identical systems, i copy the system from my server to the
system. only in etc are differences because i don't want it to start the same
processes as my server and other processes can't be started with the
configuration of the server.
if i was not crazy, this will drive me crazy!
why can i use on a system with 8 gb physical ram and 7 gb usable ram more
memory as on a system with 16GB physical and usable ram ?
goodby

No idea based on the information you provided so far. As Carlos stated on
comment #6 we need some more technical data on how to actually link these
issues with glibc itself. It could be:
* A dump analysis by either attaching gdb and dumping the core.
* A coredump due the aforementioned memory exhaustion along with the binary.
* A testcase that stress such issue linking it to a glibc interface.
Otherwise it can countless issues with the vague technical information you
provided. Also keep in mind we do not have much developers working on glibc
side, so it would be unlikely if someone will actually pursuit to check out
this issue if you do not provide a way to *actually* reproduce it.
Just dumping random information about some experiments is not the correct way
to open a bug against glibc. Check out other glibc bug reports to have a grasp
what kind of information you will need to provide us.

--- Comment #9 from dieter ferdinand <dieter.ferdinand at gmx dot de> ---
hello,
the problem is, that chrome/chromium starts a new process for every task, so it
is impossible to trace all.
i can log the memory-usage of the system and the error-message or can try to
check how many memory i can allocate with memtester.
i don't know, how i can get the information which you want.
this is not one process which makes problems. the problem is tat i get out of
memory with more then 10 gb of availabe memory or if some process like chromium
allocate much memory in a very short time!
at the moment, i have a virtual size for every chrome-process like this:
20876 dieter 20 0 807840 226216 84600 S 0,7 1,4 18:13.81 chrome
18853 dieter 20 0 1458940 186224 70656 S 0,0 1,1 173:52.01 chrome
21987 dieter 20 0 710472 179192 22340 S 0,3 1,1 41:39.29 chrome
20496 dieter 20 0 757240 128556 28204 S 0,0 0,8 14:13.67 chrome
21515 dieter 20 0 561164 120440 76568 S 0,0 0,7 1:07.86 chrome
12950 root 20 0 2673928 89100 7792 R 98,7 0,5 1858:49 TMPGEnc.exe
5357 dieter 20 0 674432 76756 16264 S 0,0 0,5 7:19.20 chrome
22053 dieter 20 0 875196 56288 19956 S 1,3 0,3 145:04.11 chrome
20968 dieter 20 0 632740 55836 27860 S 0,0 0,3 5:42.53 chrome
18223 dieter 20 0 691952 55660 30648 S 0,0 0,3 127:21.16 chrome
5468 dieter 20 0 735424 55592 13964 S 0,3 0,3 78:08.28 chrome
i think, the virtual size of chrome exceed 30GB
and this is the memory-status:
KiB Mem : 16393256 total, 576408 free, 2220832 used, 13596016 buff/cache
KiB Swap: 8380412 total, 4749532 free, 3630880 used. 13911028 avail Mem
a tool, which i get from sombody report this for chrome:
1.0 GiB + 99.1 MiB = 1.1 GiB chrome (67)
and pmap -X calculate for chrome 37 090 672 bytes.
and pmap -X for all:
Size Rss Pss Referenced Anonymous ShmemPmdMapped Shared_Hugetlb
Private_Hugetlb Swap SwapPss Locked Mapping
76480008 3511412 1884084 3220560 1706164 0 0
0 4837468 2937521 2723 KB
but what is the REAL memory-usage? the best value for total memory-usage (1.8
GiB) comes from the ps_mem-python-script.

So far you have indicate that *chrome* is misbehaving regarding memory
allocation (which is not an usual thing given its internet reputation).
Nevertheless, you must indicate that this is indeed caused by a glibc issue
instead of something from other project. The only indication you gave us so
far is you have updated your distro and it come with an update glibc, but also
potentially with multiple updates (other miscellaneous libraries and kernel).
So this potentially issue can 1. chrome itself, 2. any potentially library
chrome uses (on my chrome installation it is linked against 81 libraries), 3.
libc (although as indicated by previous comments chrome itself does not use
libc allocator), 4. kernel, 5. mist (configuration issue, etc).
So I would recommend you to open an issue on chrome bug report with this
information. If it is not an know issue, they will prob track it down and
report back to us if this is the case. You can try to run chrome with a memory
profiler (valgrind) or build with memory instrumentation (asan), however this
is out of the scope of this bugzilla and it would to seek out this information
outside it.
Unfortunately without further information on how this is linked on glibc I am
afraid I can't help you out.

--- Comment #16 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
GLIBC 2.24+ now does not cache the pid anymore and posix_spawn was rewritten
with do pretty much as the second example in comment #15 exemplifies. We still
require a non-null stack for clone even with CLONE_VM, but current approach
potentially solves commend #9 (which was not the intended bug report by the
way).
Also, as Rich commented in #12, vfork was deprecated for various reason we I
think we shouldn't bring it back as well.
I am inclined to consider this issue OBSOLETE and I will close it down in next
week (12th may 2017) if I got not reply.

--- Comment #11 from dieter ferdinand <dieter.ferdinand at gmx dot de> ---
hello,
you donÄt understand my. chrome is not the problem itself, but the most time, i
have the problem, chrome is running because chrome need much memory.
if i start chromebuilding with some processes and chrome is running, the
build-process will fail. i must terminate chrome to compile chrome or it can be
help, if if i limit to one compiler-process.
i convert videos with a windows programm and wine and if i use much memory and
run chrome and firefox with many open windows, converting fails with out of
memory.
what i want to know is: why get i out of memory, if there are more then 10 gb
available and more then 10gb is used as cache.
i don't hope, that the priority use of memory is changed to use it as cache
instead for programs as it is in windows.

--- Comment #10 from Florian Weimer <fweimer at redhat dot com> ---
Perhaps we should do the following:
(1) -c should add //IGNORE to the conversions if not already there.
(2) The conversion functions should be adjusted to make progress in //IGNORE.
See bug 13541.
(3) If the iconv function does not make progress, skip over individual input
bytes. With (2), this is only used as a last resort, to avoid a hang.
We can probably implement (1) and (3) for this bug. (2) is mostly a
charset-specific quality issue after that. Even then, the scope of this bug is
a bit larger than what I expected.

--- Comment #4 from Florian Weimer <fweimer at redhat dot com> ---
I agree that option (2) (never return EILSEQ with //IGNORE) makes the most
sense.

Bug ID: 21474
Summary: resolv: res_init does not use RES_DFLRETRY (2) but 4
for retry value
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
Various resolver initialization paths use 4 as the retry value, not
RES_DFLRETRY (2). Implicit initialization (the most common approach) uses 2,
so we should just replace the number 4 in the alternative initialization code.

Are you sure this is also true in glibc project? I haven't found such mechanism
here.
> So changes for "sr" would be:
> јуни > јун
> јули > јул
Serbian Cyrillic months are already "јун" and "јул" both in CLDR [1] and glibc,
I guess this is correct. But Serbian Latin are "jun" and "jul" in CLDR [2]
while "juni" and "juli" in glibc. I think you can test this in your computer.
The question is whether the change from "juni" to "jun" and "juli" to "jul" in
Serbian Latin is correct and, while at this, whether the current Serbian
Cyrillic months "јун" and "јул" are correct and require no change. This all
applies to the full month names in the nominative case.

commit 5df4854ed21641e5f82e17677fc385e05480ce3a
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu May 11 14:15:26 2017 +0000
Condition some sys/ucontext.h contents on __USE_MISC (bug 21457).
Continuing the fixes for namespace issues arising from sys/ucontext.h,
this patch conditions various definitions, that are not needed for
defining mcontext_t / ucontext_t, on __USE_MISC, so they do not appear
in strict POSIX modes.
This patch is non-exhaustive; that is, it only conditions
straightforward cases and there may be more such definitions that can
be conditioned for these and other architectures, to be dealt with
later in separate patches. Also, using __USE_MISC is the minimum
change for these definitions where they conflict with POSIX; some
headers already have __USE_GNU conditionals on similar definitions of
names for registers. The patch specifically does not do anything with
definitions in bits/sigcontext.h, and nor does it condition any
inclusions of bits/sigcontext.h even where in fact that is not needed
on some architectures for the definitions of mcontext_t / ucontext_t.
As other namespace issues in these headers remain, this patch does not
fix bug 21457, nor allow any XFAILs to be removed.
Tested with build-many-glibcs.py.

powerpc: Fix signal handling in backtrace
Now with read consolidation which uses SYSCALL_CANCEL macro, a frame
pointer is created in the syscall code and this makes the powerpc
backtrace obtain a bogus entry for the signal handling patch.
It is because it does not setup the correct frame pointer register
(r1) based on the saved value from the kernel sigreturn. It was not
failing because the syscall frame pointer register was the same one
for the next frame (the function that actually called the syscall).
This patch fixes it by setup the next stack frame using the saved
one by the kernel sigreturn. It fixes tst-backtrace{5,6} from
the read consolidation patch.
Checked on powerpc-linux-gnu and powerpc64le-linux-gnu.
* sysdeps/powerpc/powerpc32/backtrace.c (is_sigtramp_address): Use
void* for argument type and use VDSO_SYMBOL macro.
(is_sigtramp_address_rt): Likewise.
(__backtrace): Setup expected frame pointer address for signal
handling.
* sysdeps/powerpc/powerpc64/backtrace.c (is_sigtramp_address): Use
void* for argumetn type and use VSDO_SYMBOL macro.
(__backtrace): Setup expected frame pointer address for signal
handling.

Consolidate Linux read syscall
This patch consolidates the read Linux syscall implementation on
sysdeps/unix/sysv/linux/read.c. This leads to a different frame
pointer creation on some architectures:
* It fixes BZ#21428 on aarch64, since now the returned address
for the read syscall can be correctly found out by
backtrace_symbols.
* It makes tst-backtrace{5,6} fails on powerpc due an issue on
its custom backtrace implementation. It is fixed on subsequent
patch from this set.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
arch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.
[BZ #21428]
* include/unistd.h (read): Add hidden proto.
* io/Makefile (CFLAGS-read.c): New rule.
* nptl/Makefile (CFLAGS-read.c): New rule.
* sysdeps/unix/sysv/linux/read.c: New file.

Consolidate Linux creat implementation
This patch consolidates the creat Linux syscall implementation on
sysdeps/unix/sysv/linux/creat{64}.c. The changes are:
1. Remove creat{64} from auto-generation syscalls.list.
2. Add a new creat{64}.c implementation. For architectures that
define __OFF_T_MATCHES_OFF64_T the default creat64 will create
alias to required creat symbols.
3. Use __NR_creat where possible, otherwise use internal open{64}
call with expected flags.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
arch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.
* io/Makefile (CFLAGS-creat.c): New rule.

Consolidate Linux open implementation
This patch consolidates the open Linux syscall implementation on
sysdeps/unix/sysv/linux/open{64}.c. The changes are:
1. Remove open{64} from auto-generation syscalls.list.
2. Add a new open{64}.c implementation. For architectures that
define __OFF_T_MATCHES_OFF64_T the default open64 will create

--- Comment #12 from dieter ferdinand <dieter.ferdinand at gmx dot de> ---
hello,
i have added 43gb (rest of free space from my ssd) swap space so i get this
memory-info:
KiB Mem : 16393256 total, 7871892 free, 4401804 used, 4119560 buff/cache
KiB Swap: 53771724 total, 52920264 free, 851460 used. 11696616 avail Mem
with more then 50gb swap-space, i don't get the out of memory message and it
seems, that all programs run fine.
but why need i so much swap space, if it is not used ?
after adding the swap space, i can test 8 gb ram with memtester, before i add
the swap, i can only test 1 gb memory and with my tests to test 8gb ram, i kill
some programs.
this is very crazy.
goodby

--- Comment #3 from Kirill Tkhai <ktkhai at virtuozzo dot com> ---
Florian, I've just tested the latest master branch:
~/glibc$ git branch
* master
And the commit you said presents in the branch:
~/glibc$ git branch -a --contains c579f48edba88380635ab98cb612030e3ed8691e |
grep master
* master
[skipped]
But the test still fails:
~$sudo ./a
a: ../sysdeps/nptl/fork.c:150: __libc_fork: Assertion `THREAD_GETMEM (self,
tid) != ppid' failed.
I've configured the glibc using standard parameters and used the article from
wiki to build the test:
1)~/glibc-build$ CC=gcc-4.9 ../glibc/configure
--prefix=/home/kirill/fake-prefix-2.25
2)https://sourceware.org/glibc/wiki/Tips_and_Tricks/How_to_Build_an_application_with_your_own_custom_glibc
Please, take a look again

Yes, the assert is still present. I should have checked whether it was removed
in the commit. It is bogus.

This comment is incorrect. $ORIGIN is not completely ignored in AT_SECURE
programs.

Bug ID: 21488
Summary: ldd --unused seems to have opposite from stated
behavior
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org

Hi,
ldd -u (--unused) should "print unused direct dependencies". Running ldd -u on
an example binary claims to print list of "unused direct dependencies".
However, this list coincides exactly with objdump -p <binary > | grep NEEDED,
which makes me think that it is printing the list of actual direct
dependencies, as opposed to its complement.
See below:
$ ldd --unused static-build/linux-generic-amd64/wkhtmltox/bin/wkhtmltopdf
Unused direct dependencies:
/usr/lib/x86_64-linux-gnu/libXrender.so.1
/usr/lib/x86_64-linux-gnu/libfontconfig.so.1
/usr/lib/x86_64-linux-gnu/libfreetype.so.6
/usr/lib/x86_64-linux-gnu/libXext.so.6
/usr/lib/x86_64-linux-gnu/libX11.so.6

/lib/x86_64-linux-gnu/librt.so.1
/lib/x86_64-linux-gnu/libm.so.6
/lib/x86_64-linux-gnu/libgcc_s.so.1
/lib64/ld-linux-x86-64.so.2
$ objdump -p static-build/linux-generic-amd64/wkhtmltox/bin/wkhtmltopdf | grep

I have confirmed this on ldd (Ubuntu GLIBC 2.24-9ubuntu2) 2.24 and ldd (Ubuntu
EGLIBC 2.19-0ubuntu6.11) 2.19. --unused appears to have been introduced in
glibc 2.3.4.

--- Comment #3 from Andreas Schwab <schwab@linux-m68k.org> ---
I think the caller is supposed to always call xdr_string with XDR_FREE, even if
XDR_DECODE failed. That needs a test case to demonstrate that this isn't the
case here.

Except when the caller supplied the buffer, I assume.
Should we fix this as a non-security QoI issue?

Note that other XDR functions like xdr_array and xdr_reference have the same
issue.

--- Comment #3 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Chris, I am seeing now after my preadv/pwritev consolidation that x32 is
passing the argument on which I assume is the expected kernel ABI:
"R00" (fd), "R01" (vector), "R02" (count), "R03" ((long) (offset)), "R04"
((long) (((uint64_t) (offset)) >> 32))
There is no _ALIGNMENT_ARG extra offset in it. I will close this bug, please
reopen if the issue still happens on tilegx32.

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
This is essentially two questions that are not necessary related to each other:
1. Is there a performance regression with tan over glibc releases?
2. Why tan and tanf have different performance?
For 1. I ran the reference benchmark over different glibc version using a
binary built with GCC 5.4.0 plus with "-O3 -fno-builtin" (to force libm call to
tan{f}) using a Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz:
tan:
2.16 - 0m3.245s
2.17 - 0m3.467s
2.18 - 0m1.420s
2.19 - 0m1.449s
2.20 - 0m1.467s
2.21 - 0m1.584s
2.22 - 0m1.448s
2.23 - 0m2.336s
2.24 - 0m1.795s
2.25 - 0m1.605s
2.26 (master)- 0m1.468s
NOTE: all glibcs were built using the same compiler/linker (GCC 5.4.0).
It seems that we got a small regression on 2.23, but it seems fixed on 2.26
(master). I won't bother with this regression, so I consider this to not be an
issue. One remark: since this analysis was done on x86_64, another possible
regression could be unnoticed on other architectures (although it would be more
due compiler itself than glibc since sysdeps/ieee754/dbl-64/s_tan.c is used on
all architectures).
Now for 2. tanf and tan uses completely different implementation that operates
with different intrinsic types with different precision and constrains. You
should not expect both to have similar performance.
If you profile the benchmark (using master branch) you will see that
computation is dominated by the multiprecision tan code
(sysdeps/ieee754/dbl-64/mptan.c):
62.41% ld-linux-x86-64 libm.so [.] __mul
12.86% ld-linux-x86-64 libm.so [.] sub_magnitudes
11.24% ld-linux-x86-64 libm.so [.] add_magnitudes
7.30% ld-linux-x86-64 libm.so [.] __tan_avx
1.96% ld-linux-x86-64 libm.so [.] __acr
0.98% ld-linux-x86-64 libm.so [.] __sqr
0.89% ld-linux-x86-64 libm.so [.] __cpy
0.85% ld-linux-x86-64 libm.so [.] __c32
0.44% ld-linux-x86-64 libm.so [.] __sub
0.44% ld-linux-x86-64 libm.so [.] __add
0.12% ld-linux-x86-64 libm.so [.] __dbl_mp
0.09% ld-linux-x86-64 test-bz17211 [.] main
This is the slowest path for tan, however it allows results with more
precision.
The float counterpart in the other hand is a more simpler algorithm and
profiling indicates it dominates by the tanf kernel itself:
100.00% ld-linux-x86-64 libm.so [.] __kernel_tanf
0.00% env [unknown] [k] 0xffffffff811c0b53
There is room for tan improvement and one option would to give an option to
whether or not use the multiprecision slow path (in a short trading precision
for performance).

--- Comment #4 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Extending my last comment with more info. Although not indicated in bug
report, the original issue is present at least on 2.19 (in fact I think it is
before, since 2.19 was the version tilegx, tilepro was moved from ports to
libc) and fixed on 2.24.
Before 2.24, generic wordsize-32 p{read,writev}{64} was wrongly defined used
p{read,write} semantic for off{64}_t and kernel ABI defines is different with
always have the low and high part:
fs/read_write.c:
836 SYSCALL_DEFINE5(preadv, unsigned long, fd, const struct iovec __user *,
vec,
837 unsigned long, vlen, unsigned long, pos_l, unsigned long,
pos_h)
838 {
There is no compat symbol, as for p{read,write}{64} for p{read,write}v{64} to
handle off_t (with the exception of x86_64 as a matter of optimize argument
passing and it redefined the LO_HI_LONG macro).
Back to GLIBC code, 2.23 for instance have:
tile kernel-features.h:
#define __ASSUME_ALIGNED_REGISTER_PAIRS 1
------
#ifdef __ASSUME_ALIGNED_REGISTER_PAIRS
#define __ALIGNMENT_ARG 0,
#define __ALIGNMENT_COUNT(a,b) b
#else
#define __ALIGNMENT_ARG
#define __ALIGNMENT_COUNT(a,b) a
#endif
-----
preadv - sysdeps/unix/sysv/linux/generic/wordsize-32/preadv.c
ssize_t
__libc_preadv (int fd, const struct iovec *vector, int count, off_t offset)
{
assert (sizeof (offset) == 4);
return SYSCALL_CANCEL (preadv, fd,
vector, count, __ALIGNMENT_ARG
__LONG_LONG_PAIR (offset >> 31, offset));
}
preadv64 - sysdeps/unix/sysv/linux/generic/wordsize-32/preadv64.c
ssize_t
__libc_preadv64 (int fd, const struct iovec *vector, int count, off64_t offset)
{
return SYSCALL_CANCEL (preadv, fd,
vector, count, __ALIGNMENT_ARG
__LONG_LONG_PAIR ((off_t) (offset >> 32),
(off_t) (offset & 0xffffffff)));
}
-----
Which built on tilegx32 to (I simplified output to outline just the argument
passing for kernel ABI):
preadv.os:
"R00" (fd), "R01" (vector), "R02" (count), "R03" (0), "R04" (offset), "R05"
(offset >> 31)
preadv64.os:
"R00" (fd), "R01" (vector), "R02" (count), "R03" (0), "R04" ((off_t) (offset &
0xffffffff)), "R05" ((off_t) (offset >> 32))
Which is indeed was the bug report indicated (the extra 'alignment' argument
that
tile ABI expects for 64-bit argument passing, but that is not expected for
p{read,write}v{64} kernel ABI on R03 register).
It was indeed fixed on 2.24 with the generic p{read,write}v{64} consolidation:
/* Provide a macro to pass the off{64}_t argument on p{readv,writev}{64}. */
#define LO_HI_LONG(val) \
(long) (val), \
(long) (((uint64_t) (val)) >> 32)
ssize_t
preadv (int fd, const struct iovec *vector, int count, off_t offset)
{
return SYSCALL_CANCEL (preadv, fd, vector, count, LO_HI_LONG (offset));
}
ssize_t
preadv64 (int fd, const struct iovec *vector, int count, off64_t offset)
{
return SYSCALL_CANCEL (preadv64, fd, vector, count, LO_HI_LONG (offset));
}
Which translates to tilegx32 as:
preadv
"R00" (fd), "R01" (vector), "R02" (count), "R03" ((long) (offset)), "R04"
((long) (((uint64_t) (offset)) >> 32))
preadv64
"R00" (fd), "R01" (vector), "R02" (count), "R03" ((long) (offset)), "R04"
((long) (((uint64_t) (offset)) >> 32))
Without the extra 0 argument.

--- Comment #2 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
In fact this behavior is not currently followed by any architecture I can check
(aarch64, arm, alpha, hppa, m68k, mips, mips64, mips64n32, powerpc, powerpc64,
powerpc64le, s390x, sh, sparc, sparc64, and x86).
And I think we should not change current behavior for 3 main reasons:
1. POSIX 2008 removed this SySV interface for a good reason and changing this
behavior adds nothing for current portable code. POSIX 2001 specification does
states that stack should be saved [1] and current GLIBC code does in a
arch-specific manner (inside the mcontext_t) which allows the setcontext to
work correctly.
2. Changing this behavior would potentially require compat symbols and I see no
gain in adding compat symbols for deprecated interfaces.
3. Also, for comment #2, it is up to kernel do setup the contents for
ucontext_t and currently it does not provide the stack information as well.
Trying to change it is also another fix that does not worth the possible gains.
Instead my proposal is to make it clear the current interface behavior in glibc
documentation and close this bug as invalid.

Summary: Assignment inside an assert statement should issue a
warning
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jimis at gmx dot net
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Having an assignment inside an if statement causes "gcc -Wall" to issue a
warning "suggest parentheses". However this does not happen for assert()
statements, hiding behaviour that can cause subtle but nasty side-effects.
Example code:
assert(param = NULL);
Compiling with gcc -Wall does not print any warning.

Does this reproduce if you use testrun.sh?

Thanks for the prompt response! I was testing on Ubuntu 16.04 LTS with glibc
2.23 and on Fedora with glibc 2.24, and my quick search in bugzilla didn't find
the bug you linked to. Unfortunately I don't have a system with newest glibc to
test, but I trust it works, so closing ticket then as duplicate!

Not sure, and most likely not true if the Latin and Cyrilic names differ.

OK. So the Cyrilic names are fine, while the latin names should be changes to
"jun" and "jul" as you proposed. Sorry for making some confusion about this.

I think -u is only useful with -r or if the object was linked with -znow.

It is a Linux kernel regression. 4.11 is fine. Current git tree fails.

--- Comment #3 from Razi Shaban <razi at google dot com> ---
Hi Andreas,
What do you mean by "-u is only useful with -r" ?
Does -u have the opposite from its stated effect on your build as well?
If you could point me towards the source for ldd, I would be willing to look
into a patch.
thanks,
Razi

File: sunrpc/svc_udp.c
Function: svcudp_reply()
When IP_PKTINFO is defined, __sendmsg() can be called with mesgp->msg_iov set
incorrectly causing junk to be sent. The problem does not occur when IP_PKTINFO
is not defined and __sendto() is used.
When svcudp_reply() is called, mesgp->iov should be pointing at the iovec
structure at the start of xp_pad. This is apparently not always the case.
I discovered this while debugging an amd (am-utils) problem. When
svc_sendreply() is called in nfs_quick_reply() (in am-utils) the first time
after a successful mount junk gets sent.
If I modify nfs_quick_reply() to set mesgp->msg_iov correctly each time before
calling svc_sendreply() then the correct RPC packet is sent.
I note that mesgp->msg_iov and mesgp->msg_iovlen are explicitly set for each
call in svcudp_recv() and I wonder if the same should be done in
svcudp_reply().

Summary: get-dynamic-info assertion incorrectly triggered for
i686 on x86_64 : 'Assertion `info[DT_RPATH] == NULL'
failed!'
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal

Component: nptl

Reporter: jason.vas.dias at gmail dot com

Target Milestone: 2.26
This did not happen when building glibc-2.24 in an identical way, for i686
(Intel Atom) on an x86_64 (Haswell) :
$ ./ld.so --list /tmp/hello32
Inconsistency detected by ld.so: get-dynamic-info.h: 143: elf_get_dynamic_info:
Assertion `info[DT_RPATH] == NULL' failed!
But neither the glibc-2.25 (-m32) ld.so , NOR the test file made with
$ gcc -m32 -o /tmp/hello32 ~/hello.c
have any DT_RPATH or DT_RUNPATH set ! :
$ readelf -d /lib32/ld-linux.so.2 | grep PATH
0x0000000f (RPATH) Library rpath: []
$ strings /tmp/hello32 | grep ld-linux
/lib32/ld-linux.so.2
$ readelf -d /tmp/hello32 | grep PATH
$
Aha ! It appears my build of the 32-bit ld.so has an EMPTY RPATH .
I don't know how it got there, because I did not specify that glibc
should use an RPATH .
The configuration arguments and environment variable settings for the 32-bit
build that resulted in the useless ld.so were:
$ /usr/os_src/glibc/configure --prefix=/usr --libdir=/usr/lib32 \
--enable-shared --without-selinux --disable-werror \

I don't know how any RPATH got into the ld.so, let alone an EMPTY one .
There is no occurrence of the string 'RPATH' or 'RUNPATH' anywhere in
the config.log of the 'configure' command (extract shown above) .
As I said, building 32-bit executables used to work fine on glibc 2.24 -
any ideas why this is now happening ?
Maybe I should raise a binutils bug on the fact that ld(1) is inserting
an EMPTY RPATH ? This is a bit silly - what effect is an EMPTY RPATH meant
to have ? But where is this empty RPATH coming from ? I did not specify it.

The 64-bit ld.so has NO RPATH setting. I can't explain how one got into
the 32-bit ld.so .

output of : $ gcc -m32 -mtune=atom -dumpspecs
The GCC specs show there is NO RPATH being generated by GCC for any 32-bit
object by default. So the GLIBC code MUST be adding an RPATH somewhere to ld.so
.

--- Comment #3 from Jason Vas Dias <jason.vas.dias at gmail dot com> ---
OK, I've re-configured and rebuilt everything from scratch,
to ensure there is NOTHING in my configuration environment
that could possibly trigger any -R / -rpath setting :
$ env | grep LD
$ env | grep \\-R
$ env | grep \\-rpath
$ /usr/os_src/glibc/configure --prefix=/usr --libdir=/usr/lib32
--enable-shared --without-selinux --disable-werror --build=i686-pc-linux-gnu
--host=i686-pc-linux-gnu --target=i686-pc-linux-gnu 2>&1 | tee configure.log
$ egrep -i 'rpath|run_path|\-R' configure.log
checking for i686-pc-linux-gnu-readelf... no
checking for -fno-toplevel-reorder -fno-section-anchors... yes
$ make -j4 ...
( now build fails, because: )
I can now reproduce this issue with the command:
$ gcc -m32 -nostdlib -nostartfiles -shared
-o /usr/build/linux/glibc-x86/elf/ld.so.new \
-Wl,-z,combreloc -Wl,-z,relro -Wl,--hash-style=both -Wl,-z,defs
\
/usr/build/linux/glibc-x86/elf/librtld.os \
-Wl,--version-script=/usr/build/linux/glibc-x86/ld.map
\
-Wl,-soname=ld-linux.so.2 \
-Wl,-defsym=_begin=0
$ echo $?; readelf -d ld.so.new | grep PATH
0
0x0000000f (RPATH) Library rpath: []
$
AARGH! where is this empty RPATH coming from ?
I'm going to have to change the assert to add:
assert ((info[DT_RPATH] == NULL) || (info[DT_RPATH][0] == '\0'))

--- Comment #4 from Jason Vas Dias <jason.vas.dias at gmail dot com> ---
Created attachment 10056
--> https://sourceware.org/bugzilla/attachment.cgi?id=10056&action=edit
output from adding '-Wl,--verbose' to command line
Log file from :
$ gcc --verbose -Wl,--verbose -m32 -nostdlib -nostartfiles -shared -o
/usr/build/linux/glibc-x86/elf/ld.so.new -Wl,-z,combreloc -Wl,-z,relro
-Wl,--hash-style=both -Wl,-z,defs /usr/build/linux/glibc-x86/elf/librtld.os
-Wl,--version-script=/usr/build/linux/glibc-x86/ld.map
-Wl,-soname=ld-linux.so.2 -Wl,-defsym=_begin=0 2>&1 | tee /tmp/ld-v.log
The ld-v.log does not contain any of the strings
'-R', '-rpath', LD_RUN_PATH , or lib32, in ways
that would cause any DT_RPATH or DT_RUNPATH setting - see:
$ egrep -i 'rpath|run_path|\-R|lib32' /tmp/ld-v.log
...
nothing that would set the RPATH there.
There are no occurrences of RPATH, RUNPATH or lib32 in the ld.map file.
So where is this empty RPATH coming from ??

--- Comment #5 from Jason Vas Dias <jason.vas.dias at gmail dot com> ---
I suspect the answer might be that I compiled libc 2.24 with
binutils 2.27, and am now using binutils 2.28 ?
Maybe this is actually a ld 2.28 bug ?

so there really is NO rpath setting going on.
That log was produced by gcc and ld both in verbose mode producing ld.so .
There is no evidence of anything that would create a DT_RPATH setting
on the ld or gcc command lines logged.
Hence, I have no option but to patch glibc locally to remove empty RPATH
settings:
$ gendiff glibc .2.25
diff -up glibc/elf/get-dynamic-info.h.2.25 glibc/elf/get-dynamic-info.h

Is this from the elf/ subdirectory in a build tree? Please try:
$ ./ld.so --library-path .. --list /bin/true

--- Comment #9 from Jason Vas Dias <jason.vas.dias at gmail dot com> ---
Ok, so that was the wrong patch - problem still happens, because
the DT_RPATH element of 'info' is actually set to an Elf32_Dyn
symbol containing NO data :
$ gdb --args ./ld.so --list /tmp/hello32
...
(gdb) b /usr/os_src/glibc/elf/get-dynamic-info.h:142
Breakpoint 1 at 0x4f48: file get-dynamic-info.h, line 142.
(gdb) run
Starting program: /usr/build/linux/glibc-x86/elf/ld.so --list /tmp/hello32
Breakpoint 1, elf_get_dynamic_info (temp=0x0, l=0x56579538 <_rtld_local+1304>)
at get-dynamic-info.h:148
148 assert (info[DT_RUNPATH] == NULL);
(gdb) p info
$1 = (Elf32_Dyn **) 0x56579558 <_rtld_local+1336>
(gdb) p *info
$2 = (Elf32_Dyn *) 0x0
(gdb) p info[DT_RUNPATH]
No symbol "DT_RUNPATH" in current context.
...
( so then I lookup DT_RPATH & DT_RUNPATH in /usr/include/elf.h :
..
(gdb) p info[15]
$3 = (Elf32_Dyn *) 0x56578f3c
(gdb) p *info[15]
$4 = {d_tag = 15, d_un = {d_val = 0, d_ptr = 0}}
(gdb) p *info[29]
Cannot access memory at address 0x0
So there actually is an EMPTY element (d_val == 0) there.
And nothing on any gcc or ld command line seems to explain this.
I'll change the patch to explicitly test if
info[DT_RPATH].d_val == 0
.

ldd -u is working as designed. With lazy binding none of the libraries (except
libc) are initially used. Only applying the function relocations can mark the
libraries as being used.

--- Comment #10 from Jason Vas Dias <jason.vas.dias at gmail dot com> ---
Aha ! Thanks, Andreas - I think my environment did have an EMPTY
LD_RUN_PATH setting .
But I think maybe it is a bug that ld 2.28 goes ahead and creates
a DT_RPATH element because of an EMPTY $LD_RUN_PATH , without
any explicit -rpath or -runpath argument .
I will filter it out & rebuild .
Thanks,
Jason

Bug ID: 21502
Summary: Excessive memory allocation due to LD_HWCAP_MASK
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: siddhesh at sourceware dot org
Reporter: siddhesh at sourceware dot org
Target Milestone: ---
It was discovered that setting LD_HWCAP_MASK to a large numeric value results
in significant memory allocation in the dynamic linker and sometimes results in
malloc failure, causing the program to crash. A simple test like this
demonstrates the problem:
LD_HWCAP_MASK=0xffffffffffffffff /bin/true
On a system with constrained overcommit, this should fail with the following
error:
/bin/true: error while loading shared libraries: cannot create capability list:
Cannot allocate memory
or at least take a very long time to finish.

If this is working as intended, perhaps we can change the documentation to
better explain how ldd is working? This is confusing and certainly appears
to have the opposite from its stated effect.

_dl_important_hwcaps wants to create all combinations of the unmasked hwcap
strings. On x86_64 there are 28 hwcaps, computing those 2^28 combinations
takes its time.

--- Comment #8 from Vincent Lefèvre <vincent-srcware at vinc17 dot net> ---
Similarly, assuming the defect in the C standard mentioned in bug 21360, the
following program:
#include <stdio.h>
int main(void)
{
long n = -1;
snprintf (NULL, 0, "%100000000000s%ln", "", &n);
printf ("%ld\n", n);
return 0;
}
outputs -1 instead of 100000000000 on x86_64 (64-bit long's).
Note: This may be regarded as being above the environmental limits, but nothing
seems to be documented about them, and it would be better to get the expected
result anyway.

Actually, I'm not sure of what is expected in case of overflow on the return
value. I've just asked in the Austin Group mailing-list:

This is a different issue. I'm not talking about the size argument, but the 'n'
format specifier.

They are related. I'm not sure if it is reasonable to expect that if snprintf
fails with EOVERFLOW, %n output has been written.

Bug 14771 comment 4 was about a conflict between ISO C and POSIX, and doesn't
give a hint here.
> I'm not sure if it is reasonable to expect that if snprintf fails with
> EOVERFLOW, %n output has been written.
There is no %n output. %n allows one to get information about the length of
some sequence of characters. According to bug 21360, one should get a
"meaningful" value, even for something that would *never* be output. So, if one
follows this idea, it could be reasonable to expect a meaningful value if int
is too small for the return value, e.g. to overcome the limitation of the int
type.

Commit 045c13 (*) Consolidate Linux setrlimit and getrlimit implementation -
https://patchwork.ozlabs.org/patch/685203/ breaks the LTP and and documented
behavior, causing terminated programs which handled errors by checking retcode:
Expected result of setrlimit() with an invalid struct rlimit pointer (-1) from
man ugetrlimit:
EFAULT A pointer argument points to a location outside the accessible address
space.
Actual result with glibc-2.25 (and I expect also 2.24 due to same code):
Program receives SIGBUS on x86-32 and SIGSEGV on other archs like ppc32.
Maybe, only 32 bit archs are affected.
Program received signal SIGBUS, Bus error.
(gdb) bt
#0 __setrlimit (resource=RLIMIT_NOFILE, rlim=0xffffffff) at
../sysdeps/unix/sysv/linux/setrlimit.c:40
__setrlimit (enum __rlimit_resource resource, const struct rlimit *rlim)
{
# ifdef __NR_prlimit64
struct rlimit64 rlim64;
if (rlim->rlim_cur == RLIM_INFINITY) <=== This is line 40.
#1 0x08049be4 in main (ac=1, av=0xbffffc54) at setrlimit02.c:95
TEST(setrlimit(TC[i].resource, TC[i].rlim));
The test case calls setrlmit() with 0xffffffff and expect EFAULT as documented.
Commit 045c13
(*) The offending change to __setrlimit() was added by Commit 045c13:+int
+__setrlimit (enum __rlimit_resource resource, const struct rlimit *rlim)
+{
+# ifdef __NR_prlimit64
+ struct rlimit64 rlim64;
+
+ if (rlim->rlim_cur == RLIM_INFINITY)
+ rlim64.rlim_cur = RLIM64_INFINITY;
+ else
+ rlim64.rlim_cur = rlim->rlim_cur;
+ if (rlim->rlim_max == RLIM_INFINITY)
+ rlim64.rlim_max = RLIM64_INFINITY;
+ else
+ rlim64.rlim_max = rlim->rlim_max;
+
+ int res = INLINE_SYSCALL_CALL (prlimit64, 0, resource, &rlim64, NULL);
+ if (res == 0 || errno != ENOSYS)
+ return res;
+# endif
+ return INLINE_SYSCALL_CALL (setrlimit, resource, rlim);
+}
For comparsion, sysdeps/unix/sysv/linux/setrlimit64.c from glibc-2.23:
setrlimit64 (enum __rlimit_resource resource, const struct rlimit64 *rlimits)
{
#ifdef __ASSUME_PRLIMIT64
return INLINE_SYSCALL (prlimit64, 4, 0, resource, rlimits, NULL);
#else
# ifdef __NR_prlimit64
int res = INLINE_SYSCALL (prlimit64, 4, 0, resource, rlimits, NULL);
if (res == 0 || errno != ENOSYS)
return res;
# endif
struct rlimit rlimits32;
if (rlimits->rlim_cur >= RLIM_INFINITY)
rlimits32.rlim_cur = RLIM_INFINITY;
else
rlimits32.rlim_cur = rlimits->rlim_cur;
if (rlimits->rlim_max >= RLIM_INFINITY)
rlimits32.rlim_max = RLIM_INFINITY;
else
rlimits32.rlim_max = rlimits->rlim_max;
return __setrlimit (resource, &rlimits32);
#endif
}
It appears to me, taht the RLIM_INFINITY are not for prlimit64, but commit
045c13 does it in __setrimit as shown above.
Since commit 045c13, Joseph Myers changed some code to assume that prlimit64 is
always available:
ttps://sourceware.org/git/?p=glibc.git&a=search&h=HEAD&st=commit&s=rlimit
But it appears he missed a few places :
glibc-2.25$ grep -r INLINE_SYSCALL_CALL.*etrlimit
sysdeps/unix/sysv/linux/setrlimit64.c: res = INLINE_SYSCALL_CALL (setrlimit,
resource, &rlimits32);
sysdeps/unix/sysv/linux/getrlimit.c: return INLINE_SYSCALL_CALL (ugetrlimit,
resource, rlim);
sysdeps/unix/sysv/linux/getrlimit.c: return INLINE_SYSCALL_CALL (getrlimit,
resource, rlim);
sysdeps/unix/sysv/linux/getrlimit64.c: if (INLINE_SYSCALL_CALL (ugetrlimit,
resource, &rlimits32) < 0)
sysdeps/unix/sysv/linux/setrlimit.c: return INLINE_SYSCALL_CALL (setrlimit,
resource, rlim);
With the RLIM_INFINITY checks removed completely, (if what I saw that they are
obsolete, is indeed true) this issue should be resolved too.

--- Comment #2 from Siddhesh Poyarekar <siddhesh at sourceware dot org> ---
HJ's patch fixed that by setting dl_hwcap to 0 since x86 uses the cpu_features
struct. So this is fixed by bug #21391.

As explained in POSIX, EFAULT is never guaranteed and receipt of a signal
is always OK as an alternative.

--- Comment #2 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
This bug is invalid in imho, LTP is relying on undefined behavior by providing
an invalid pointer as 'struct rlimit' object location. What you states as
'documented behavior' is in fact the Linux man pages with current behavior, not
the conformance standard (POSIX in this case) or any other contract for
extension or such alike.
POSIX in this specific case [1] states EINVAL `shall` be returned for:
[EINVAL]
An invalid resource was specified; or in a setrlimit() call, the new rlim_cur
exceeds the new rlim_max.
And 'may' fail with:
[EINVAL]
An invalid resource was specified; or in a setrlimit() call, the new rlim_cur
exceeds the new rlim_max.
Pointer valid is out the scope and thus I think LTP should be adjusted to
correctly check for the POSIX interface (which is what GLIBC aims to provide)
or call the syscall directly to check for the Linux kernel ABI.
I will close this bug as INVALID.

Just to be clear, I meant that since EFAULT is not guarantee (as Joseph pointed
out) and the standard does not define an invalid pointer as EINVAL, glibc
implementation is following POSIX.

libio: Avoid dup already opened file descriptor [BZ#21393]
As described in BZ#21398 (close as dup of 21393) report current
freopen implementation fails when one tries to freopen STDIN_FILENO,
STDOUT_FILENO, or STDERR_FILENO. Although on bug report the
discussion leads to argue if a close followed by a freopen on the
standard file is a valid operation, the underlying issue is not
really the check for dup3 returned value, but rather calling it
if the returned file descriptor is equal as the input one.
So for a quality of implementation this patch avoid calling dup3
for the aforementioned case. It also adds a dup3 error case check
for the two possible failures, with one being Linux only: EINTR and
EBUSY. The EBUSY issue is better explained on this stackoverflow
thread [1], but in a short it is due the internal Linux
implementation which allows a race condition window for dup2 due
the logic dissociation of file descriptor allocation and actual
VFS 'install' operation. For both outliers failures all allocated
memory is freed and a NULL FILE* is returned.
With this patch the example on BZ#21398 is now actually possible
(I used as the testcase for the bug report). Checked on
x86_64-linux-gnu.
[BZ #21393]
* libio/freopen.c (freopen): Avoid dup already opened file descriptor
and add a check for dup3 failure.
* libio/freopen64.c (freopen64): Likewise.
* libio/tst-freopen.c (do_test): Rename to do_test_basic and use
libsupport.
(do_test_bz21398): New test.
* manual/stdio.texi (freopen): Add documentation of EBUSY failure.

Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue May 23 11:49:48 2017 +0000
Fix sys/ucontext.h namespace from signal.h etc. inclusion (bug 21457).
The various sys/ucontext.h headers include <signal.h> and all the
headers split out of <bits/sigstack.h>. (Except that the powerpc
version does not include <signal.h>.)
None of the standard versions defining ucontext.h require or permit
such inclusions; rather, they all say that the stack_t and sigset_t
types from signal.h are defined. This patch fixes the headers to
include just the bits/ headers for those types (and the existing
includes of bits/sigcontext.h). Since bits/types/sigset_t.h is now
being included instead of bits/types/__sigset_t.h, __sigset_t uses in
the headers are replaced by direct use of the public sigset_t type.
sysdeps/unix/sysv/linux/x86/bits/sigcontext.h was relying on the prior
inclusion of <signal.h> to define types such as __uint32_t, so gets a
bits/types.h include added to provide those types.
Although one could keep some or all of the includes under a __USE_MISC
conditional, that seems unnecessary to me, especially given the lack
of a <signal.h> include in the powerpc version meaning that portable
programs already cannot rely on such an include.
Tested for x86_64 and x86, and with build-many-glibcs.py. As with
other such fixes, more namespace issues remain so this does not permit
any XFAILs to be removed or bugs to be closed.
[BZ #21457]
* sysdeps/arm/sys/ucontext.h: Do not include <signal.h>,
<bits/sigstack.h>, <bits/types/struct_sigstack.h> or
<bits/ss_flags.h>. Include <bits/types/sigset_t.h> instead of
<bits/types/__sigset_t.h>.

Bug ID: 21512
Summary: clone() ends up calling exit_group() through _exit()
wrapper
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: attila at sty dot hu
CC: drepper.fsp at gmail dot com
Target Milestone: ---
At least on the x86_64 architecture (but maybe on all), after the user function
of the clone() wrapper returns, the _exit() glibc wrapper is called instead of
syscall(SYS_exit,...):
from sysdeps/unix/sysv/linux/x86_64/clone.S:
/* Call exit with return value from function call. */
movq %rax, %rdi
call HIDDEN_JUMPTARGET (_exit)
This may end up in the exit_group() system call:
from sysdeps/unix/sysv/linux/_exit.c:
#ifdef __NR_exit_group
INLINE_SYSCALL (exit_group, 1, status);
#endif
INLINE_SYSCALL (exit, 1, status);
which is not the right thing to do (at least for the CLONE_THREAD clones, but
maybe for none of them) because the "man clone(2)" documentation states
explicitly:
"After all of the threads in a thread group terminate the parent process of the
thread group is sent a SIGCHLD (or other termination) signal."
So a return from the user function should not kill the whole process (thread
group), just that one particular thread which we returned from.

commit 666c0c5efa6db73632a6894bf028fef9f3b60d71
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue May 23 16:47:29 2017 +0000
Fix sigstack namespace (bug 21511).
The sigstack function was removed in the 2001 edition of POSIX, and
the sigstack structure in the 2008 edition. signal.h wrongly includes
those declarations even for newer POSIX versions. This patch fixes
the conditions, and conform/ expectations, accordingly.
This patch makes the minimum change to when these declarations are
present, leaving them visible for __USE_MISC as they would previously
have been visible by default. Arguably these legacy declarations
should only be visible when an old standard is specifically requested,
but implementing that would require arranging for the various sigstack
implementations to be able to see the struct sigstack type despite it
not being in _GNU_SOURCE in that case.
Tested for x86_64.
[BZ #21511]
* signal/signal.h: Include <bits/types/struct_sigstack.h> only if
[(__USE_XOPEN_EXTENDED && !__USE_XOPEN2K8) || __USE_MISC].
(sigstack): Declare only if [(__USE_XOPEN_EXTENDED &&
!__USE_XOPEN2K) || __USE_MISC].
* conform/data/signal.h-data (struct sigstack): Expect type only
if [!XOPEN2K8 && !POSIX2008].
(sigstack): Expect function only if [XPG42 || UNIX98].

Florian, based on comment and git log it seems this bug as fixed by

Bug ID: 21513
Summary: pthread_cleanup_push macro generates warning when
-Wclobbered is set
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: pcarroll at codesourcery dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
There is an open issue filed against the Gcc Middle-End - Bugzilla #61118.
In this issue, it is noted that the use of the pthread_cleanup_push macro from
pthread.h will generate 2 warnings when -Wclobbered is set.
The warnings are for the '__cancel_routine' and '__cancel_arg' variables that
are created as part of the macro definition.
The warning occurs because of the presence of a sigsetjmp() call after those 2
variables are defined.
As is noted in the Bugzilla issue, one solution to the issue would be to fix
the Gcc Middle-End, so as to recognize that the pthread_cleanup_push macro is
coming from a system header and thus suppress the warning.
In the absence of a GCC fix, another possible solution is to modify the macro
definitions in pthread.h so as to mark those variables as 'volatile'.
The changes would be made to both pthread_cleanup_push and
pthread_cleanup_push_defer_np macro definitions. The changes would make the
macros look something like this:
# define pthread_cleanup_push(routine, arg) \
do { \
__pthread_unwind_buf_t __cancel_buf; \
void (* volatile __cancel_routine) (void *) = (routine); \
void * volatile __cancel_arg = (arg); \
:
Since those variables are now reloaded whenever they are used and thus will not
be clobbered by the setjmp, the compilation will be quiet.
An interesting side effect is that, for an ARM compilation, the resulting
object file for the Bugzilla #61118 test case generated 24 less bytes of text,
with a few less memory references.
An alternative to using 'volatile' could potentially involve using '#pragma GCC
diagnostic' or '_Pragma("GCC diagnostic")' to have the compiler ignore the
warning for those 2 macros, but my attempts to use those failed.
And that would only be valid if those warnings are truly irrelevant to these
macros, in that those variables could never be clobbered.
These warnings become more important when customers use -Werror and expect no
warnings at compilation time.

This is because _LIBC is no longer defined when the testsuite files are

Summary: struct sigaltstack namespace
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
glibc defines the stack_t type with the tag struct sigaltstack. This is not
permitted by POSIX; sigaltstack is only reserved with file scope in the
namespace of ordinary identifiers, not the tag namespace, and in the case where
stack_t is obtained from ucontext.h rather than signal.h, it's not reserved
with file scope at all.

Bug ID: 21521
Summary: getmntent, getmntent_r buffer size handling
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Flags: security-
getmntent_r currently ignores everything after the first 4 KiB, and does not
have a way to request more buffer space from the caller. I think we need to
introduce an ERANGE protocol (similar to the NSS functions), or perhaps
deprecate getmntent_r and fix only getmntent.
Related bug report: http://bugs.alpinelinux.org/issues/5703
The Alpine Linux example only slightly exceeds 1024 bytes, which is why it
works on glibc, but that isn't really guaranteed (PATH_MAX itself already is 4
KiB).

Does the warning reflect an actual bug in the macro, or is it false positive?

The variables are used after sigsetjmp returned the second time, so this is a
real bug.

Is it? Why don't we save callee-saved variables in the jump buffer? Shouldn't
this enable fixing the issue (perhaps with a little help from GCC for
returns_twice function calls)?
If GCC recognizes the situation to the degree that it can issue a warning, why
doesn't it generate code which does not have the problem?

> The warning is about undefined behaviour.
Sorry for being unclear. I don't understand if this warning indicates a
genuine code generation problem for this particular compilation, or if it is a
warning about a potential portability hazard. But perhaps the difference does
not matter.

commit 2667457e45fda874afae5ebe3fe37bc74dbc7202
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Aug 26 22:40:27 2016 +0200
malloc: Simplify static malloc interposition [BZ #20432]
Existing interposed mallocs do not define the glibc-internal
fork callbacks (and they should not), so statically interposed
mallocs lead to link failures because the strong reference from
fork pulls in glibc's malloc, resulting in multiple definitions
of malloc-related symbols.

malloc: Run tests without calling mallopt [BZ #19469]
The compiled tests no longer refer to the mallopt symbol
from their main functions. (Some tests still call mallopt
explicitly, which is fine.)

Possible test case to add into the glibc nptl directory
Of course, the Makefile would need to be modified to add this file as well.

Bug ID: 21530
Summary: tmpfile() should be implemented using O_TMPFILE
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: crrodriguez at opensuse dot org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
On linux, tmpfile(3) should be implemented opening dir with O_TMPFILE|O_EXCL
instead of the current approach.
if open() returns EISDIR, ENOENT or EOPNOTSUPP it should fallback to the old
method.

--- Comment #2 from John David Anglin <danglin at gcc dot gnu.org> ---
Defining _LIBC in these tests doesn't resolve the problem building these tests.
The failing tests break the testsuite as a whole. Thus, it's difficult to
access changes.

--- Comment #3 from Zack Weinberg <zackw at panix dot com> ---
I'm not sure I'm going to be able to reproduce this in cross compilation,
because I should have seen it when testing the _ISOMAC patches.
It would really help if one of you could provide me with complete, unedited,
single-threaded build logs, i.e. starting from an empty directory
$ ../glibc/configure --whatever
$ make all > build.log 2>&1
$ make -k check > check.log 2>&1
and attach build.log and check.log to this bug (compressed).
Thanks.

int fclose(FILE *fp);
ERRORS
EBADF
The file descriptor underlying fp is not valid.
Current glibc doesn't follow POSIX. It causes segmentation violation (SEGV)
Should simply do
if(NULL == fp)
{
errno = EBADF;
return -1;
}

--- Comment #2 from Jon Grant <jg at jguk dot org> ---
I appreciate it is not in a specification, but NULL clearly is never going to
be a valid handle? Is it not better to reject it with EBADF or EFAULT? So
application can get the return code and appropriately handle it.

Does the garbage have any discernible pattern?
Does am-utils do anything strange with the order in which the server functions
are called?

A stream is not a descriptor, and NULL is never a stream, so it doesn't have a
descriptor in the first place.

Right now it is not even possible to *build* a cross-compiled glibc for hppa
using unmodified trunk and the build-many-glibcs automation, because of:

I assume the issue is that you can't fully validate the patches you're working
on because of the testsuite failures, so could you please post them to the
mailing list anyway?

Andreas: Which platform did you observe that check-local-headers.out failure
on? I don't see it on any of the platforms I can build (again, using
build-many-glibcs).

Yes, I have a fairly large patch file. Attached is build log and my patch
file.
Most of these patches have been sent to the list previously but I'm working on
trying to test
a patch for recent pthread changes (mainly the initializers).
If the tests are looking for the current system syscall.h files, they are here:
dave@mx3210:~$ find /usr/include -name syscall.h
/usr/include/syscall.h
/usr/include/hppa-linux-gnu/sys/syscall.h
/usr/include/hppa-linux-gnu/bits/syscall.h

No it isn't. I don't see it on a normal x86-64-linux native build nor on any
build-many-glibcs cross build.

Thanks. For me, with this patch applied on top of current git master,
build-many-glibcs $workdir compilers hppa-linux-gnu succeeds, and
build-many-glibcs $workdir glibcs hppa-linux-gnu shows only these test
failures:
FAIL: elf/check-execstack
FAIL: elf/check-textrel
Summary of test results:
2 FAIL
1149 PASS
31 XFAIL
I also manually checked: check-local-headers.out is an empty file;
nptl/tst-cond24 and nptl/tst-cond25 were successfully created (but I can't run
them). There must be something else going on.
Here is the command line that failed for you:
gcc tst-cond24.c -c -std=gnu11 -fgnu89-inline -O2 -Wall -Werror -Wundef
-Wwrite-strings -fmerge-all-constants -fno-stack-protector -frounding-math -g

I have a bad feeling that this is a cross-compilation/native-compilation
issue...

Summary: Update locale data to Unicode 10.0
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: maiku.fabian at gmail dot com
CC: libc-locales at sourceware dot org
Target Milestone: ---
As soon as Unicode 10.0.0 is released, the locale data that was updated for
Unicode 9.0 (bug 20313) should be updated to 10.0.0.
Currently Unicode 10.0.0 is in the beta phase, I am working on the
update of the glibc locale data to be ready when Unicode 10.0.0 is released.

arguments broken with positional arguments
Product: glibc
Version: 2.25

Created attachment 10077
--> https://sourceware.org/bugzilla/attachment.cgi?id=10077&action=edit
tst-vfprintf-user-type.c
If %P has an arginfo function which requests more than one argument, and it is
used as a positional argument specified (%1$P), the additional arguments are
not taken into account when computing the total number of arguments in
vfprintf/printf_positional (and possibly the offsets as well).
This means that the last subtest in the attached test program crashes.
This could perhaps be a documentation issue. It is not entirely clear how
positional indexes would be determined if a format specifier consumes multiple
arguments.

OK. So let's fix that.
Notice that the patch supplied here (so long ago):
http://www.cygwin.com/ml/libc-hacker/2010-10/msg00014.html
is called "Don't require DNS labels to be host names". Requiring DNS labels to
be hostnames is the bug, right? And it is still a problem.

The only headers in my build directory, objdir, are

So, the compile doesn't find "./objdir/misc/bits/syscall.h".

--- Comment #5 from ma.jiang at zte dot com.cn ---
Hi, all
I think this bug is not just about nss, it's more serious. A shared library
dlopened by static executables could depend on libpthread. The writer of this
shared library did nothing wrong, neither did the user of the library（who
dlopen the library in a static executable）. But the final program just can not
act as expected because of this bug.
Generally speaking, the dlopened shared libraries and the static executable
should be isolated from each other. The main executable use dlsym to access the
functions provided by the shared libraries. Glibc currently support this usage,
so we should try to make things right.
In fact, there have been dl-static.c which provided a standard way to
initialize variables in the dynamic linker ld.so. Unfortunately, this file
currently just initialize the dl_pagesize. More over, many main stream
architectures(such as arm/x86) did not even implement this file.
To fix this bug , I have unified dl-static.c, and added some lines to
initialize GL(dl_error_catch_tsd). See the attached patch for more details.
Hope this local fix could go upstream.

Patches should be sent to the mailing list. Current master no longer has
dl_error_catch_tsd, as part of the fix for bug 16628.
Do you have a test case? Maybe this bug has been fixed as well?

--- Comment #8 from ma.jiang at zte dot com.cn ---
(In reply to Florian Weimer from comment #7)
Hi,
Thanks for your quick reply.
> Patches should be sent to the mailing list. Current master no longer has
> dl_error_catch_tsd, as part of the fix for bug 16628.
> Do you have a test case? Maybe this bug has been fixed as well?
Yes, you are right, After the fix in
"https://sourceware.org/git/?p=glibc.git;a=commit;h=9e78f6f6e7134a5f299cc8de77370218f8019237"
applied. This bug should be gone. Currently, I'm using glibc-2.24 and I just
checked the dl-static.c in the trunk... Sorry for this miss.
But, I think the main part of this patch(a unified dl-static.c) still should
be applied. Anyway,We should initialize variables in ld.so when the main
executable is static linked(and dlopen some shared libraries).
Currently, I cannot post mail to the mailing list as there were some problems
in our email system... I'll post the patch later after our email system get
fixed.

Bug ID: 21536
Summary: sysconf(_SC_NPROCESSORS_ONLN) errno is set wrongly on
success
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: ptikhomirov at virtuozzo dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
In Virtuozzo containers we have access to sysfs prohibited for most of the
files for security reasons. Running the code below in container I get false
negative errno:
/# ls /sys/devices/system/cpu/online
ls: cannot access /sys/devices/system/cpu/online: No such file or directory
/# rpm -qa glibc
glibc-2.17-157.el7_3.2.x86_64
/# cat sysconf_nrproc_onln.c
#include <stdio.h>
#include <unistd.h>
#include <errno.h>
int main()
{
long nrproconln;
printf("Before: errno=%d\n", errno);
nrproconln = sysconf(_SC_NPROCESSORS_ONLN);
printf("After: nrproc_onln=%ld errno=%d\n", nrproconln, errno);
return 0;
}
/# gcc -o sysconf_nrproc_onln sysconf_nrproc_onln.c
/# ./sysconf_nrproc_onln
Before: errno=0
After: nrproc_onln=4 errno=2
In sysconf man we have:
RETURN VALUE
If name is invalid, -1 is returned, and errno is set to EINVAL.
Otherwise, the value returned is the value of the system resource
and errno is not changed.
But in my case errno is 2 but should stay zero accoring to man.
I can see with gdb:
Breakpoint 3, __get_nprocs () at ../sysdeps/unix/sysv/linux/getsysstats.c:151
151 int fd = open_not_cancel_2 ("/sys/devices/system/cpu/online", flags);
(gdb) p errno
$10 = 0
(gdb) c
Continuing.
Breakpoint 4, __get_nprocs () at ../sysdeps/unix/sysv/linux/getsysstats.c:154
154 if (fd != -1)
(gdb) p errno
$11 = 2
(gdb) c
Continuing.
Breakpoint 6, __get_nprocs () at ../sysdeps/unix/sysv/linux/getsysstats.c:199
199 fd = open_not_cancel_2 ("/proc/stat", flags);
(gdb) p errno
$12 = 2
(gdb) c
Continuing.
Breakpoint 7, __get_nprocs () at ../sysdeps/unix/sysv/linux/getsysstats.c:200
200 if (fd != -1)
(gdb) p errno
$13 = 2
Function __get_nprocs tries to read nrprocesses from sysfs, fails and sets
errno==2, fall-backs to read nrprocesses from proc, succeeds but never resets
errno back.
Our real problem is that docker(which we run in container) uses
C.sysconf(C._SC_NPROCESSORS_ONLN) and checks error using errno!=0 as according
to man it should not change from 0 by sysconf.

sysconf did not return -1, so the value of errno is undefined.

In sysconf man it is said completely the contrary, as I've already wrote in my
previous message:
"Otherwise, the value returned is the value of the system resource and errno is
NOT CHANGED."

--- Comment #4 from Siddhesh Poyarekar <siddhesh at sourceware dot org> ---
(In reply to Pavel Tikhomirov from comment #0)
> Our real problem is that docker(which we run in container) uses
> C.sysconf(C._SC_NPROCESSORS_ONLN) and checks error using errno!=0 as
> according to man it should not change from 0 by sysconf.
To elaborate, here is what POSIX says[1]:
"If name is an invalid value, sysconf() shall return -1 and set errno to
indicate the error. If the variable corresponding to name is described in
<limits.h> as a maximum or minimum value and the variable has no limit,
sysconf() shall return -1 without changing the value of errno."
This means that the value of errno is defined only when sysconf() returns -1.
This is reiterated further in the APPLICATION USAGE section where applications
are advised as follows:
"As -1 is a permissible return value in a successful situation, an application
wishing to check for error situations should set errno to 0, then call
sysconf(), and, if it returns -1, check to see if errno is non-zero."

"Basically, Ulrich only wanted to solve a particular problem, namely building
upon NIST-approved crypto, and so he introduced SHA-crypt, thereby solving the
problem. bcrypt is unrelated to that problem, so it didn't get in, and its
OpenBSD origin didn't help either.
Now that Ulrich is no longer involved, things may be different."

The current NSS interface does not support combined host/service lookups. NSS
service modules only see the host name. This would have to be fixed first,
probably by returning a struct addrinfo list directly from the service module,
which requires significant interface changes.

commit 139904b7e454b1232dc7807dd613682d107daab1
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu Jun 1 14:07:40 2017 +0000
Fix more namespace issues in sys/ucontext.h (bug 21457).
Continuing the fixes for namespace issues in sys/ucontext.h, this
patch moves various symbols into the implementation namespace in the
absence of __USE_MISC. As with previous changes, it is nonexhaustive,
just covering more straightforward cases.
Structure fields are generally changed to have a prefix __ in the
absence of __USE_MISC, via a macro __ctx (used without a space before
the open parenthesis, since the result is a single identifier).
Various macros such as NGREG also have leading __ added. No changes
are made to structure tags (and thus to C++ name mangling), except
that in the (unused) file sysdeps/i386/sys/ucontext.h, structures
defined inside other structures as the type for a field have their
tags removed in the non-__USE_MISC case (those structure tags would
not in any case have been visible in C++, because in C++ the scope of
such a tag is limited to the containing structure). No changes are
made to the contents of bits/sigcontext.h, or to whether it is
included. Because of remaining namespace issues, this patch does not
yet fix the bug or allow any XFAILs to be removed.
Tested for x86_64 and x86, and with build-many-glibcs.py.

--- Comment #12 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
I *think* there may be an ordering issue with check-local-headers; if it
runs at the start of a testsuite run it examines only .d files from the
build of glibc itself, but if run later it also examines .d files from the
build of the testsuite.
I'm not sure how best to ensure it gets run at the end of a testsuite run
not the start, and it would be better anyway for it to be run in each
directory for that directory's .d files after the other tests in that
directory are run (as a step towards getting rid of the special logic for
toplevel tests and just keeping the logic for subdirectory tests).
The above is of course only tangentially related to the present bug, in
that it might be helpful in working out how to reproduce the reported
symptom of check-local-headers failures.

--- Comment #13 from Zack Weinberg <zackw at panix dot com> ---
> The only headers in my build directory, objdir, are

Digging into this a bit more, my build-many-glibcs runs are picking up
bits/syscall.h from outside the build environment! This is the relevant bit of
a gcc -H dump of the compilation that ought to fail...
. ../include/errno.h
.. ../stdlib/errno.h
... ../sysdeps/unix/sysv/linux/hppa/bits/errno.h
....
/home/zack/projects/glibc-many/install/compilers/hppa-linux-gnu/sysroot/usr/include/linux/errno.h
.....
/home/zack/projects/glibc-many/install/compilers/hppa-linux-gnu/sysroot/usr/include/asm/errno.h
......
/home/zack/projects/glibc-many/install/compilers/hppa-linux-gnu/sysroot/usr/include/asm-generic/errno-base.h
. ../include/sys/types.h
. ../sysdeps/unix/sysv/linux/sys/syscall.h
..
/home/zack/projects/glibc-many/install/compilers/hppa-linux-gnu/sysroot/usr/include/asm/unistd.h
..
/home/zack/projects/glibc-many/install/compilers/hppa-linux-gnu/sysroot/usr/include/bits/syscall.h
... ../sysdeps/wordsize-32/bits/wordsize.h
It happens that this is a relatively up-to-date bits/syscall.h, because the
sysroot in .../install/compilers/hppa-linux-gnu/sysroot contains a complete
installed glibc from an earlier phase of the glibc-many process, but it still
represents a failure of build isolation. You have the same problem, your
native builds are doing -isystem /usr/include, which would have masked the
problem if your installed glibc had a bits/syscall.h.
(This also explains why Andreas claimed that this problem happens "everywhere".
It _does_, but it's masked by the build-many-glibcs setup and it's also masked
in a native build where the system has a /usr/include/bits/syscall.h.
check-local-headers isn't failing for me because Debian puts bits/syscall.h in
/usr/include/$(canonical_host), and check-local-headers.sh ignores anything
that looks like it's in a subdirectory named after a config.sub triple. _LIBC
is only relevant because the Linux sys/syscall.h has an #ifndef _LIBC in it to
paper over a build sequencing problem (bits/syscall.h might not get generated
sufficiently early). Gosh, it would have been nice if you had explained in
sufficient detail for me to have understood all of that back on the 24th,
Andreas.)
I'm working on a patch.

It does but it's not in /usr/include/bits/syscall.h. Some time ago,
Debian switched to a multiarch
header structure.

commit 72b81552a1239f91054ae0c8469e6d780f79a890
Author: Zack Weinberg <zackw@panix.com>
Date: Thu Jun 1 10:56:10 2017 -0400
Add shim header for bits/syscall.h.
On Linux-based configurations, bits/syscall.h is a generated file.
To avoid build-ordering problems, the Linux sys/syscall.h only includes
bits/syscall.h if _LIBC is not defined. After the _ISOMAC-testsuite
changes, this means any test case that includes sys/syscall.h tries to
pull in bits/syscall.h. This would be fine, because it'll definitely
have been generated by the time we start compiling tests, except that
the generated <builddir>/misc/bits/syscall.h is not visible in the
include path, because nothing needed it till now. So we either get
the bits/syscall.h from the host system, or the build fails.
The fix is simple: add a shim header for bits/syscall.h. I put it in
sysdeps/unix/sysv/linux/include instead of the top-level include/
because bits/syscall.h doesn't exist at all on other configurations as
far as I can tell.
This is known to affect nptl/tst-cond2[45]. Thanks to John David
Anglin for noticing the problem.
[BZ #21514]
* sysdeps/unix/sysv/linux/include/bits/syscall.h: New shim header
pointing to the generated file in <builddir>/misc/bits/syscall.h.

Huh. I'm also on Debian, but I am not getting the -nostdinc -isystem ...
switches in my native builds. How are you configuring glibc?

--- Comment #5 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
The glibc rule is that "If it's user code invoking undefined behavior,
then it should fail early and catastrophically". Thus NULL checks, where
NULL is undefined behavior, should be avoided; an unconditional
dereference is preferred (and if for any reason there is a check because
there isn't an immediate unconditional dereference, such a check should
call assert () and terminate the program).
https://sourceware.org/glibc/wiki/Style_and_Conventions#Bugs_in_the_user_program
https://sourceware.org/glibc/wiki/Style_and_Conventions#Invalid_pointers
The *_s functions are poorly designed (even for retrofitting existing
low-quality code) and Annex K has been specifically rejected for glibc.

--- Comment #2 from Peter Linich <plinich at cse dot unsw.edu.au> ---
** Discernible pattern
I have only been able to reproduce and capture the network in a couple of
particular circumstances and in each case I observeved the following:
It occurred when amd was sending a response to an NFSv3 LOOKUP request.
Instead of sending a UDP datagram of 132 bytes, glibc sent a databgram of 8800
bytes.
The datagram appeared to consist of a LOOKUP reply (but I wasn't sure it was
the correct one) followed by 8668 NULs (i.e., '\0').
** Does amd do anything strange in regards to the order it calls functions?
Sorry. I can't answer that. I don't know what's normal for this sort of thing.
** How I isolated the problem
I will note that I downloaded both the source code of amd and of the latest
version of glibc and peppered the relevant bits of source code with printf()
and dlog() statements to narrow down where the problem was occurring.
svc_sendreply() encodes that data to send into a buffer but doesn't ensure that
this buffer is what it sends. I could see that the encoded data length was 132
bytes but that __sendmsg() returned saying it had sent 8800.

Bug ID: 21539
Summary: S390: Mismatch between kernel and glibc ptrace.h with
request 12: PTRACE_SINGLEBLOCK vs PTRACE_GETREGS.
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: stli at linux dot vnet.ibm.com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
On s390, there is a mismatch for request 12 between kernel and glibc ptrace.h.
<glibc>/sysdeps/unix/sysv/linux/s390/sys/ptrace.h:
/* Get all general purpose registers used by a processes.
This is not supported on all machines. */
PTRACE_GETREGS = 12,
#define PT_GETREGS PTRACE_GETREGS
<kernel>/arch/s390/include/uapi/asm/ptrace.h:
#define PTRACE_SINGLEBLOCK 12 /* resume execution until next branch
*/
>From the kernel perspective PTRACE_GETREGS/PTRACE_SETREGS has never existed on
s390/s390x. The definitions in glibc header has always been wrong and no
application could have been expected to work.
Thus the glibc definitions have to be adjusted in order to match the kernel
ones.

Bug ID: 21542
Summary: Use conservative default for sysconf
(_SC_NPROCESSORS_ONLN)
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Currently, if running in a chroot environment without /proc and /sys, sysconf
(_SC_NPROCESSORS_ONLN) can return 1 on a multi-processor system. This breaks
applications which use the return value to recognize uniprocessor systems and
apply optimizations based on that.
ysconf (_SC_NPROCESSORS_ONLN) should return 2 instead, which is a more
conservative approximation. It can be inefficient, but at least it will not be
completely incorrect.

commit 9c65eec494676789bc4695561e229ce3ee33be84
Author: Joseph Myers <joseph@codesourcery.com>
Date: Fri Jun 2 19:47:03 2017 +0000
Fix sigevent namespace (bug 21543).
signal.h defines the sigevent structure and constants if defined
__USE_POSIX199309 || defined __USE_XOPEN_EXTENDED. The
__USE_XOPEN_EXTENDED condition is incorrect; this structure does not
appear in XSI standards before Unix98 (which implies
__USE_POSIX199309). This patch fixes the conditionals accordingly
(the existing conditional is correct for siginfo_t, just not for
sigevent).
Tested for x86_64. This does not allow any conform/ XFAILs to be
removed because of other signal.h namespace bugs.
[BZ #21543]
* signal/signal.h: Only include <bits/types/sigevent_t.h> and
<bits/sigevent-consts.h> if [__USE_POSIX199309], not if
[__USE_XOPEN_EXTENDED].

Bug ID: 21544
Summary: stdio fprintf, printf returning >0 after underlying fd
closed
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: dslowik500 at gmail dot com
Target Milestone: ---
As in the code below,
After opening a regular file FILE *fp to write to, then closing the underlying
file descriptor, a call to fprintf on fp returns number of chars given to
fprintf. I think it should return -1 as an strace shows that first fprintf
seems to trigger a call to fstat on the underlying fd which fails with EBADF
errno. fprintf will return -1 only after enough chars have been added into the
stdio buffer to trigger a write syscall, and that write error is propagated
back through fprintf, but not the initial fstat error. The question is: Should
fprintf report the error when it first detects it through fstat or wait until
write later reports the same error?
[Note that if the fd is closed 'after' first fprintf call, it will have to wait
for a full stdio buffer to trigger write to detect error; but I'm thinking
first error detected should be reported by stdio in either case.]
A similar thing happens with printf writing to stdout after closing
STDOUT_FILENO. That code and discussion is at:
https://stackoverflow.com/questions/44034025/stdio-to-terminal-after-closestdout-fileno-behavior
OS:
Linux HAL 4.4.0-79-generic #100-Ubuntu SMP Wed May 17 19:58:14 UTC 2017 x86_64
x86_64 x86_64 GNU/Linux
compiler:
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609
code for fprintf to regular file:
#include <unistd.h>
#include <stdio.h>
#include <string.h>
#include <errno.h>
int main() {
FILE *fp = fopen("out.txt", "w");
// Close underlying file descriptor:
int fd = fileno(fp);
close(fd);
// write fails:
if (write(fd, "Direct write\n", 13) != 13)
fprintf(stderr, "Error on write after close(fd): %s\n", strerror(errno));
// but fprintf() calls continue fine, ferror(fp) = 0, until first write()
call on filled stdio buffer:
int rtn = 1, cum = 0;
errno = 0;
// while (rtn>0) { // uncomment while loop to fill stdio buffer.
if ((rtn = fprintf(fp, "fprintf after close(fd)\n")) < 0 || ferror(stdout))
fprintf(stderr, "Error on fprintf after close(fp): %s\n",
strerror(errno));
cum += rtn;
fprintf(stderr, "fprintf returned %d, cum: %d\n", rtn, cum);
// }
// Only on fflush is error detected (if write not yet triggered above):
if (fflush(fp) || ferror(fp))
fprintf(stderr, "Error on fflush(fp): %s\n", strerror(errno));

commit 7553131847151d04d58a02300673f13d73861cbb
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jun 5 10:17:46 2017 +0000
Fix struct sigaltstack namespace (bug 21517).
glibc defines the stack_t type with the tag struct sigaltstack. This
is not permitted by POSIX; sigaltstack is only reserved with file
scope in the namespace of ordinary identifiers, not the tag namespace,
and in the case where stack_t is obtained from ucontext.h rather than
signal.h, it's not reserved with file scope at all.
This patch removes the tag accordingly and updates uses in glibc of
struct sigaltstack. This is similar to the removal of the "struct
siginfo" tag a few years ago: C++ name mangling changes are an
unavoidable consequence. A NEWS item is added to note the changed
mangling. There is inevitably some risk of breaking builds of
anything that relies on the struct sigaltstack name (though the first
few hits I looked at from codesearch.debian.net generally seemed to
involve code that could use the stack_t name conditionally, so
depending on how they determine the conditionals they may work with
glibc not defining the struct tag anyway).
Tested for x86_64 and x86, and with build-many-glibcs.py.
[BZ #21517]
* bits/types/stack_t.h (stack_t): Remove struct tag.

commit c4c96f92f76dbc03a04a0e5005bf0be6f8dd4138
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jun 5 10:19:03 2017 +0000
Define SIG_HOLD for XPG4 (bug 21538).
Various bits/signum.h headers define SIG_HOLD if __USE_UNIX98. That
should be __USE_XOPEN, as this macro is in XPG4. This patch fixes the
conditionals accordingly. Because of other header bugs, this does not
allow any XFAILs to be removed (however, the XPG4/signal.h/conform
XFAIL only depends on a few such straightforward header bugs, not on
the more complicated to fix ucontext_t issues, as ucontext_t isn't
included in signal.h in XPG4).
Tested for x86_64.
[BZ #21538]
* bits/signum.h (SIG_HOLD): Define if [__USE_XOPEN], not
[__USE_UNIX98].
* sysdeps/unix/bsd/bits/signum.h (SIG_HOLD): Likewise.
* sysdeps/unix/sysv/linux/alpha/bits/signum.h (SIG_HOLD):
Likewise.
* sysdeps/unix/sysv/linux/bits/signum.h (SIG_HOLD): Likewise.
* sysdeps/unix/sysv/linux/hppa/bits/signum.h (SIG_HOLD): Likewise.
* sysdeps/unix/sysv/linux/mips/bits/signum.h (SIG_HOLD): Likewise.
* sysdeps/unix/sysv/linux/sparc/bits/signum.h (SIG_HOLD):
Likewise.

Summary: Tibetan script collation broken (Dzongkha and Tibetan)
Product: glibc

Status: UNCONFIRMED

Target Milestone: ---
Hello,
Tibetan or Dzongkha sorting do not work properly with the current locale data.
With the following test file:
$ cat tibt_order_test.txt
ལྔ
ང
ཅ
རྔ
སྔ
བརྔ
བསྔ
I get the following wrong result:
$ LC_COLLATE="dz_BT.utf8" sort tibt_order_test.txt
ང
བརྔ
བསྔ
རྔ
ལྔ
སྔ
ཅ
The correct result would be
ང
རྔ
ལྔ
སྔ
བརྔ
བསྔ
ཅ
Dz and bo have the same collation data in CLDR.
See https://github.com/eroux/tibetan-collation for more on tibetan collation.
Result of locale -a:
bo_CN
bo_CN.utf8
bo_IN
bo_IN.utf8
C
C.UTF-8
dz_BT
dz_BT.utf8
en_GB.utf8
en_US.utf8
fr_FR.utf8
POSIX
Thank you,

General purpose registers in mcontext_t structure
are 8 bytes long for both MIPS32/MIPS64, as per:

but get/set/make/swap context implementations for MIPS O32
incorrectly assume that general purpose registers
in this structure are 4 bytes long.

XPG4.2. Thus it should be declared only if __USE_POSIX199506; signal.h wrongly
declares it for __USE_POSIX. (sigwaitinfo is correctly conditioned on
__USE_POSIX199309.)

Bug ID: 21551
Summary: argp.h before error.h using std=c99 causes compile
error on __builtin_va_arg_pack
Product: glibc
Version: 2.17
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: matt.stclair at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Including argp.h before error.h in my source causes the following errors when
compiling using gcc 4.8.5 with the -std=c99 (or -std=c11) option:
/usr/include/bits/error.h: In function ‘error’:
/usr/include/bits/error.h:42:19: error: invalid use of ‘__builtin_va_arg_pack
()’
__error_alias (__status, __errnum, __format, __va_arg_pack ());
^
/usr/include/bits/error.h: In function ‘error_at_line’:
/usr/include/bits/error.h:71:27: error: invalid use of ‘__builtin_va_arg_pack
()’
__error_at_line_alias (__status, __errnum, __fname, __line,
This occurs even with no additional code, so it can be tested with just the
following two lines of code:
#include <argp.h>
#include <error.h>

(In reply to Ondrej Bilka from comment #2)
> Looks almost as duplicate of 15199.
I doubt it is a duplicate of 15199.
While working on rhel-5.11 / glibc 2.5 I ran into exactly the same issue as
Jeff.
You can see that TLS is broken in the code accessing __ctype_b and that the
register value is zero.
Florian Weimer and I found that this is somehow also related to prelink. If you
undo prelinking then everything works.
It may be that with prelinking the dlmopen code links the same library twice
into the same address range and the namespaces conflict?
We may never need to look at this again given that prelink isn't really being
actively developed or used by newer distributions.
I won't close this out yet, but we should at some point just close this issue.

Jeff also noted that as a requirement to expose the bug, which is why I
identified our issue as a duplicate.

Author: Joseph Myers <joseph@codesourcery.com>

Fix tst-timezone race (bug 14096).
I observed a failure of timezone/tst-timezone with the same symptoms
as reported in bug 14096.
I was unable to reproduce the failure on testing again. However, from
inspection, the cause is as follows. tst-timezone uses time zones
compiled from the northamerica file, but has no dependency on any such
zones, so with a parallel build it is possible that they do not get
compiled until after tst-timezone is run. This patch adds a
dependency on the compiled America/New_York zone (the one used as a
makefile target to cause such zones to be compiled, rather than one
which is actually used in that test) to fix the race.
Tested for x86_64.
[BZ #14096]
* timezone/Makefile ($(objpfx)tst-timezone.out): Depend on
America/New_York.

--- Comment #3 from Torvald Riegel <triegel at redhat dot com> ---
What seems to happen in your test case is that the pthread_cond_timedwait calls
always time out. POSIX states in the Thread Cancellation section of
http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html#tag_15_09
the following:
"It is unspecified whether the cancellation request is acted upon or whether
the cancellation request remains pending and the thread resumes normal
execution if:
* The thread is suspended at a cancellation point and the event for which
it is waiting occurs
* A specified timeout expired
before the cancellation request is acted upon."
I think this effectively means that an implementation can choose to act upon
the timeout before it acts upon the cancellation request. Thus, this is not a
bug.
The difference in behavior when choosing different clocks is due to differences
in when the implementation checks for timeouts (ie, before using futexes or in
the futex syscall).
Please reopen the bug if you have another test case that is correct.

--- Comment #4 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
Hi Torvald,
Thanks for your response. I understand what you're saying, and I agree in
principle.
So, when people call pthread_cond_timedwait() with the monotic clock, they will
always need to add a pthread_testcancel() to be 100% sure that the cancellation
will be handled.
thanks again,
Dimitri

--- Comment #5 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
Hi Torvald,
After re-reading the POSIX specification, I think this unspecified behaviour
you mention is only allowed if the application is already executing the
cancellation point.
I don't they allow for an implementation of pthread_cond_timedwait() to not act
on a cancellation request that is already pending.
cheers,
Dimitri

I don't see wording that would require this. I think the third sentence in the
relevant POSIX paragraph, which I quoted, is a third case distinct from the
other two.
I also don't see why this would limit what applications can do. If the
application actually enforces that pthread_cancel has finished execution in
another thread before the respective pthread_cond_timedwait call started, then
the application must be able to check whether that's the case in the condvar
wait loop. The timeout is there and it works.
One could argue that the special casing for the timeout case is not explicitly
spelled out for other kinds of errors; for example, must the implementation
check for a cancellation request before it returns EINVAL because the supplied
timeout is bogus? But would that make sense?
You could ask the Austin Group for clarification, if this issue is important to
you (but I'd suggest to include the EINVAL case as well).

I don't understand the full details yet, but I wonder if cancellation still
shortens the timeout substantially. One reason for using cancellation is
getting out of long timeouts, and we should keep support for that.

My apologies. Commits for new locales only happen when you're working directly
with a community developer that can commit this code for you. Maintainers are
listed here: https://sourceware.org/glibc/wiki/MAINTAINERS.
The review by Chris Leonard in comment #6 is proof enough that kab_DZ should be
ready for commit. Chris is known in the community and has reviewed such patches
in the past (though he is not a glibc developer).
Have you been using the new kab_DZ locale? Is it working well? Does it match
what is being submitted here? Which distro is including the locale?

Add TUNABLES to control IFUNC selection and cache sizes
The current IFUNC selection is based on microbenchmarks in glibc. It
should give the best performance for most workloads. But other choices
may have better performance for a particular workload or on the hardware
which wasn't available at the selection was made. The environment
variable, GLIBC_IFUNC=-xxx,yyy,-zzz...., can be used to enable CPU/ARCH
feature yyy, disable CPU/ARCH feature yyy and zzz, where the feature
name is case-sensitive and has to match the ones in cpu-features.h. It
can be used by glibc developers to override the IFUNC selection to tune
for a new processor or improve performance for a particular workload.
It isn't intended for normal end users.
NOTE: the IFUNC selection may change over time. Please check all
multiarch implementations when experimenting.

Add TUNABLES to control IFUNC selection and cache sizes
The current IFUNC selection is based on microbenchmarks in glibc. It
should give the best performance for most workloads. But other choices
may have better performance for a particular workload or on the hardware
which wasn't available at the selection was made. The environment
variable, GLIBC_IFUNC=-xxx,yyy,-zzz...., can be used to enable CPU/ARCH
feature yyy, disable CPU/ARCH feature yyy and zzz, where the feature
name is case-sensitive and has to match the ones in cpu-features.h. It
can be used by glibc developers to override the IFUNC selection to tune
for a new processor or improve performance for a particular workload.
It isn't intended for normal end users.
NOTE: the IFUNC selection may change over time. Please check all
multiarch implementations when experimenting.

--- Comment #4 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
At least since release 4.04, the Linux man-pages say:
On 64-bits, pow() may be more than 10,000 times slower for some (rare) inputs
than for other nearby inputs. This affects only pow(), and not powf() nor
powl().

--- Comment #9 from Belkacem Mohammed <belkacem77 at gmail dot com> ---
Hello,
Thanks for help.
I can't understand much more about technical devs . I followed a link when I
was trying to start the kab locale for openSUSE.
The kab localization of openSUSE is now ongoing but, it seems that we need kab
on glibc to release our locale.
We are also working on the kab locale on CLDR (please see
http://st.unicode.org/cldr-apps/v#/kab/). You will find all needed data.
The kab locale is now available on all Mozilla products and content (Firefox,
Thudenrbird..), Odoo and much more.
Note the iso 639-2 code of the Kabyle language is kab. Kab-DZ is same as kab.
There is no other variant for our language.
Please, let me know if you need more information
Thank you

I agree. The question here is more about what should happen if a call
immediately times out.

Bug ID: 21560
Summary: sys/wait.h signal.h namespace
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
sys/wait.h includes signal.h unconditionally. But the permission to do so is
UX-shaded in XPG4.2, and XSI-shaded in POSIX before 2008, so this should not be
unconditional.

--- Comment #9 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
I understand the arguments given, and the text can be interpreted the way
Torvald does, but they seem to me against the intent of the POSIX
specification.
POSIX states "A condition wait (whether timed or not) is a cancellation point."
It doesn't say that passing an expired timeout may lead to undefined behaviour.
To me, the clauses mentioned by Torvald have the intent to allow some leeway in
the implementation when a cancellation request arrives to a suspended thread or
a thread that timeouts, cancellation doesn't necessarily have to happen anymore
at that point and can be deferred. In other words, the implementation can
choose to check the cancellation at any time, else it'd have to check for
cancellation just before returning. But I don't think POSIX has in mind that
there is an execution path in the implementation that doesn't check the
cancellation state at all.
In the current implementation, pthread_cond_timedwait() effectively stops
behaving as a cancellation point if you pass it an expired timeout with the
monotonic clock. This may cause a lot of problems when that cond_timedwait() is
the only cancellation point in the thread, which is what the code example
revealed.

--- Comment #10 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
Also, just to clarify further:
The pthread_cond_timedwait() function shall be equivalent to
pthread_cond_wait(), except that an error is returned if the absolute time
specified by abstime passes (that is, system time equals or exceeds abstime)
before the condition cond is signaled or broadcasted, or if the absolute time
specified by abstime has already been passed at the time of the call.
So, an expired abstime is not an invalid argument. Invalid abstimes would be
where, for instance the tv_nsec is larger than 10^9.

--- Comment #11 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
Sorry, I misunderstood your comment about the EINVAL. It is a really good
question, I would think that even with invalid input, cancellation points have
to check the cancellation state before returning EINVAL.

commit 0862cdcdc814185345ab3e6eda4bb1b81efdf76a
Author: Joseph Myers <joseph@codesourcery.com>
Date: Fri Jun 9 13:45:37 2017 +0000
Condition signal.h inclusion in sys/wait.h (bug 21560).
sys/wait.h includes signal.h unconditionally. But the permission to
do so is UX-shaded in XPG4.2, and XSI-shaded in POSIX before 2008, so
this should not be unconditional. This patch fixes this
conservatively: the include is kept, but conditioned on the standards
that permit it (meaning it is still present by default, because
non-XSI POSIX.1:2008 is enabled by default). <bits/types.h> is now
included unconditionally to provide the required definition of
__pid_t; it was previously included via <signal.h>. Some standards
require pid_t to be defined here, and all allow it to be defined here;
previously defined via <signal.h>, it's now defined directly in this
header.
Tested for x86_64. This does not fix any of the sys/wait.h
conformtest failures, but substantially reduces the number of
namespace failures for sys/wait.h for XPG4 and POSIX.
[BZ #21560]
* posix/sys/wait.h: Condition include of <signal.h> on
[__USE_XOPEN_EXTENDED || __USE_XOPEN2K8]. Include <bits/types.h>
unconditionally.
[!__pid_t_defined] (pid_t): Define typedef.

Fix sigpause namespace (bug 21554).
The sigpause function is declared for __USE_XOPEN. As it's new in
XPG4.2 it should be declared only for __USE_XOPEN_EXTENDED. This
patch fixes the declaration accordingly.
Tested for x86_64.

* signal/signal.h (sigpause):: Declare if [__USE_XOPEN_EXTENDED],
not [__USE_XOPEN].

--- Comment #12 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
I'm just going to quote the full paragraph that you referenced before:
Whenever a thread has cancelability enabled and a cancellation request has been
made with that thread as the target, and the thread then calls any function
that is a cancellation point (such as pthread_testcancel() or read()), the
cancellation request shall be acted upon before the function returns. If a
thread has cancelability enabled and a cancellation request is made with the
thread as a target while the thread is suspended at a cancellation point, the
thread shall be awakened and the cancellation request shall be acted upon. It
is unspecified whether the cancellation request is acted upon or whether the
cancellation request remains pending and the thread resumes normal execution
if:
The thread is suspended at a cancellation point and the event for which it
is waiting occurs
A specified timeout expired
before the cancellation request is acted upon.
The current implementation of pthread_cond_timedwait() is clearly violating the
very first statement of this paragraph. This is definitely a bug.

Fix waitid namespace (bug 21561).
In sys/wait.h, waitid and associated constants and types are UX-shaded
in XPG4.2 (so not in XPG4), and XSI-shaded in POSIX before 2008, so
should be appropriately conditional in the headers. This patch fixes
the conditionals accordingly. (WCONTINUED is actually still
XSI-shaded in POSIX.1:2008, but W* is also reserved there without
XSI-shading, so nothing special needs to be done about the
conditionals on WCONTINUED to conform to POSIX.1:2008 namespace
rules.)
Tested for x86_64.
[BZ #21561]
* posix/sys/wait.h (idtype_t): Change [__USE_XOPEN] condition to
[__USE_XOPEN_EXTENDED].
(id_t): Likewise.
(include of <bits/types/siginfo_t.h): Likewise.
(waitid): Likewise.
* sysdeps/unix/sysv/linux/bits/waitflags.h (WSTOPPED): Condition

--- Comment #15 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
I cannot stress enough that this is a monstrous bug that leads to complete
inconsistency and instability of the library. It completely defeats the purpose
of any cancellation point with a timeout. I really hope that you haven't
implemented other cancellation points in the same way, or you will see massive
shitstorms when more and more applications start using these functions.
I'm discussing with the Austin Group to have this apparent loophole in the
newer version of the specification rectified:

--- Comment #19 from Zack Weinberg <zackw at panix dot com> ---
I'm inclined to say that all patches that simply update glibc to match CLDR
should be pre-approved. The glibc reviewers mostly don't have the knowledge
required to assess these at all, CLDR's team does, and it's silly to leave
these sorts of fixes hanging for months for lack of anyone who feels empowered
to say "yes."

There is no longer a need for string2.h, so remove it and all mention of
it.
Move the redirect for __stpcpy to include/string.h since it is still
required
until all internal uses have been renamed.
This fixes several linknamespace/localplt failures when building with -Os.

* include/string.h: Add internal redirect for __stpcpy.
* string/Makefile: Remove bits/string2.h.

* string/string-inlines.c: Remove bits/string2.h include and comment.

commit a0f8b1152040d2652cdeb741ac586c95221dc5f0
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jun 12 17:38:20 2017 +0000
Fix sigwait namespace (bug 21550).
sigwait was added to POSIX in 1995; it is not in older POSIX versions
or XPG4 / XPG4.2. Thus it should be declared only if
__USE_POSIX199506; signal.h wrongly declares it for __USE_POSIX.
(sigwaitinfo is correctly conditioned on __USE_POSIX199309.) This
patch fixes the condition on the declaration of sigwait.
Tested for x86_64. Because of other namespace problems this does not
allow any conform/ XFAILs to be removed.
[BZ #21550]
* signal/signal.h (sigwait): Only declare if [__USE_POSIX199506].

Fix XPG4 bsd_signal namespace (bug 21552).
bsd_signal was added in XPG4.2, so should be declared for
__USE_XOPEN_EXTENDED, instead of the present __USE_XOPEN condition.
This patch fixes the condition accordingly.
Tested for x86_64.
[BZ #21552]
* signal/signal.h (bsd_signal): Declare if [__USE_XOPEN_EXTENDED],
not [__USE_XOPEN].
* conform/Makefile (test-xfail-XPG4/signal.h/conform): Remove.

--- Comment #16 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
I've also found this section of POSIX:
http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html
You will find the following statement:
"For functions in the "shall occur" list, a cancellation check must be
performed on every call regardless of whether, absent the cancellation, the
call would have blocked. For functions in the "may occur" list, a cancellation
check may be performed on some calls but not others; i.e., whether or not a
cancellation point occurs when one of these functions is being executed can
depend on current conditions."
in
http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html
You will find that pthread_cond_timedwait() is in the "shall occur" list, so
this also states that this function always has to perform a cancellation check.

--- Comment #20 from Rafal Luzynski <digitalfreak at lingonborough dot com> ---
Thank you, Zack. But please don't commit yet. As written in comment 9, the
same changes as in be_BY are also required in be_BY@latin (reword "Travień" ->
"Maj"). As I wrote in comment 10, I made this change locally and pushed to my
github repo (which is available in public so you can extract the patch from it)
but I did not publish the updated patch here nor in libc_alpha list. Also I
had some feedback that while the change in es_PE is correct (comment 14) the
same change in es_UY is not. But I'd like to have it confirmed.

--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
Use of stdio streams when the underlying file descriptor has been closed is
undefined anyway. The fstat call happens on the first use only anyway, so the
additional error detection capability provided base on that would be extremely
narrow.

If C++ headers <cstdlib> or <cmath> are used, GCC 6 will include
/usr/include/stdlib.h or /usr/include/math.h from "#include_next"
(instead of stdlib/stdlib.h or math/math.h in the glibc source
directory), and this turns up as a make dependency. An implicit
rule will kick in and make will try to install stdlib/stdlib.h or
math/math.h as /usr/include/stdlib.h or /usr/include/math.h because
the target is out of date. We make a copy of <cstdlib> and <cmath>
in the glibc build directory so that stdlib/stdlib.h and math/math.h
will be used instead of /usr/include/stdlib.h and /usr/include/math.h.
worked for GCC 6. But bits/std_abs.h from GCC 7 also includes
/usr/include/stdlib.h.

The existing special case for timeouts seems to contradict this statement,
though (because it allows pthread_cond_wait to choose between acting upon the
timeout and doing the cancellation check).
I think it would still be good to get clarification from the Austin Group. The
wider question (eg, EINVAL cases) also still applies: Does the statement you
cite above apply to all calls, or only to successful ones? There is precedent
for this distinction, in that the requirements for when functions "synchronize
memory" only apply to calls that return successfully.

This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".
The branch, hjl/pr21573 has been created
at 9523a49dfad1e034ddbcf2893fca9b40e18e7c3e (commit)

https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=9523a49dfad1e034ddbcf2893fca9b40e18e7c3e
commit 9523a49dfad1e034ddbcf2893fca9b40e18e7c3e
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Tue Jun 13 04:30:26 2017 -0700
Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from
"#include_next" (instead of stdlib/stdlib.h in the glibc source
directory), and this turns up as a make dependency. Also make a copy
of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h.
[BZ #21573]
* configure.ac (find_cxx_header): Add a second argument to
support <bits/std_abs.h>.
(CXX_CSTDLIB_HEADER): Updated. Also make a copy of
<bits/std_abs.h>.
(CXX_CMATH_HEADER): Updated.
* configure: Regenerated.

commit 5b55c60163f4c99301c4c8fe2504a195620d828a
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Tue Jun 13 04:30:26 2017 -0700
Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from
"#include_next" (instead of stdlib/stdlib.h in the glibc source
directory), and this turns up as a make dependency. Also make a copy
of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h.
[BZ #21573]
* configure.ac (find_cxx_header): Use "\,$1," with sed.
(CXX_CSTDLIB_HEADER): Also make a copy of <bits/std_abs.h>.
* configure: Regenerated.

--- Comment #18 from Dimitri Staessens <dimitri.staessens at ugent dot be> ---
Hi Torvald,
I think the "existing special case for timeouts" is a bug in the POSIX
specification.
This is a previous version of the same paragraph that you have quoted:
http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html
Whenever a thread has cancelability enabled and a cancellation request has been
made with that thread as the target, and the thread then calls any function
that is a cancellation point (such as pthread_testcancel() or read()), the
cancellation request shall be acted upon before the function returns. If a
thread has cancelability enabled and a cancellation request is made with the
thread as a target while the thread is suspended at a cancellation point, the
thread shall be awakened and the cancellation request shall be acted upon.
However, if the thread is suspended at a cancellation point and the event for
which it is waiting occurs before the cancellation request is acted upon, it is
unspecified whether the cancellation request is acted upon or whether the
cancellation request remains pending and the thread resumes normal execution.
In this version, the clause that you see as a special case for timeouts is
actually relational.
In all cases, functions that are in the "shall occur" list, have to check the
cancellation state before returning, even before returning EINVAL.
I am getting clarification from the Austin Group and making sure that they fix
it in their spec. Unless I am overlooking something big.

They just provided my with the rationale:
https://collaboration.opengroup.org/austin/interps/documents/14359/AI-136.txt
It looks like the change in the clause is intentional. However, you see that it
causes contradictions. I will file a bug report with the Austin Group and keep
you in the loop. Thanks for bearing with me on this.

Summary: sys/wait.h missing struct rusage definition
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Some older standards (XPG4.2 through POSIX.1:2001, XSI only) require sys/wait.h
to include the definition of struct rusage. This is missing in glibc.

Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from
"#include_next" (instead of stdlib/stdlib.h in the glibc source
directory), and this turns up as a make dependency. Also make a copy
of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h.
[BZ #21573]
* Makerules [$(c++-bits-std_abs-h) != ""] (before-compile): Add
$(common-objpfx)bits/std_abs.h.
[$(c++-bits-std_abs-h) != ""] ($(common-objpfx)bits/std_abs.h):
New target.
* config.make.in (c++-bits-std_abs-h): New.
* configure.ac (find_cxx_header): Use "\,$1," with sed.
(CXX_BITS_STD_ABS_H): New.
(AC_SUBST(CXX_BITS_STD_ABS_H)): Likewise.
* configure: Regenerated.

Target Milestone: ---
In POSIX.1:2008, various signal stack symbols - sigaltstack, SS_*, SIGSTKSZ,
MINSIGSTKSZ - are all XSI-shaded. glibc wrongly makes them visible for non-XSI
POSIX.

x86-64: Implement strcmp family IFUNC selectors in C
Implement strcmp family IFUNC selectors in C and enable SSE4.2/AVX
strcmp/strncmp.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcmp family functions within libc.
[BZ #21572]
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
strcmp-sse2, strcmp-sse4_2, strcmp-avx, strncmp-sse2,

strncase_l-sse4_2 and strncase_l-avx.

x86-64: Implement strcmp family IFUNC selectors in C
Implement strcmp family IFUNC selectors in C and enable SSE4.2/AVX
strcmp/strncmp.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcmp family functions within libc.
[BZ #21572]
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
strcmp-sse2, strcmp-sse4_2, strcmp-avx, strncmp-sse2,
strncmp-sse4_2, strncmp-avx, strcasecmp_l-sse2,
strcasecmp_l-sse4_2, strcasecmp_l-avx, strncase_l-sse2,
strncase_l-sse4_2 and strncase_l-avx.

mips: Fix store/load gp registers to/from ucontext_t
General purpose registers in mcontext_t structure
are 8 bytes long for both MIPS32/MIPS64.
get/set/make/swap context implementations for MIPS O32
incorrectly assume that general purpose registers
in this structure are 4 bytes long.
This patch is fixing that.
Tested for MIPS O32 LE and BE.
Compared objdump of modified functions for mips n32 and mips n64.
[BZ #21548]
* sysdeps/unix/sysv/linux/mips/getcontext.S: Define MCONTEXT_SZGREG as
8 and use it when copying general purpose registers.
* sysdeps/unix/sysv/linux/mips/makecontext.S: Likewise.
* sysdeps/unix/sysv/linux/mips/mips32/Makefile: Include new test for
mips o32.
* sysdeps/unix/sysv/linux/mips/mips32/bug-getcontext-mips-gp.c: Added
new test for mips o32.
* sysdeps/unix/sysv/linux/mips/setcontext.S: Define MCONTEXT_SZGREG as
8 and use it when copying general purpose registers.
* sysdeps/unix/sysv/linux/mips/swapcontext.S: Likewise.

x86-64: Implement strcmp family IFUNC selectors in C
Implement strcmp family IFUNC selectors in C and enable SSE4.2/AVX
strcmp/strncmp.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcmp family functions within libc.
[BZ #21572]

Target Milestone: ---
I'm the coordinator for friulian translator in Gnome and TP.
There's a spelling mistake about wednesday
The correct form is Miercus (shortened Mie), actually it's written Miarcus
(Mia)
the diphthong "ie" is spelled as "ia" so maybe who translated it made a
mistake.
If you need to check the correctness of my words you can translate the italian
word for wednesday, "Mercoledì", in various dictionaries, such as:
http://www.arlef.it/grant-dizionari-talian-furlan/htdocs/gdbtf.pl/search#
or
http://claap.org/definizion/?diz=it-fur&leme=mercoled%C3%AC

Note my opinion that they are making a catastrophic mistake if they adopt the
currently suggested solution.

x86-64: Implement strcmp family IFUNC selectors in C
Implement strcmp family IFUNC selectors in C and enable SSE4.2/AVX
strcmp/strncmp.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcmp family functions within libc.
[BZ #21572]
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
strcmp-sse2, strcmp-sse4_2, strcmp-avx, strncmp-sse2,

strncase_l-sse4_2 and strncase_l-avx.

that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for memmove family functions within libc.

--- Comment #19 from Stephen Dolan <stephen.dolan at cl dot cam.ac.uk> ---
(In reply to Torvald Riegel from comment #17)

I have just added a simplified version of martin's test case, which uses
pthread_cond_wait in this textbook style but still exhibits the strange
behaviour.
On my machine (Ubuntu 16.04, glibc 2.23), it produces this output:
A waiting
signal #1 sent to waiters: a=1, b=0, c=0
B waiting
C waiting
signal #2 sent to waiters: a=1, b=1, c=1
B woke
C: timedwait returned [Success]
The program hangs at this point, and no other output is produced. Control never
returns from pthread_cond_wait in thread A.
I have not yet tested this on more recent glibc, so it's possible that this has
been fixed. Before trying other versions, though, I'd like to know whether you
think this output is correct.
The messages are printed only when holding the lock, so the happens-before
relation totally orders the lines of output. As you've mentioned, signal #2 can
go to any of the waiters (A, B or C) with no guarantee of fairness, and
spurious wakeups can occur at any moment.
However, when signal #1 is sent, only A is waiting. Threads B and C have not
started. The fact that this signal does not cause A to wake seems like a bug.

Target: i386
Shadow Stack in Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
doesn't support:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
since shadow stack doesn't match. We can use register indirect branch with
ECX as scratch register. It means that functions marked as internal_function
can't be called via PLT. One of such functions is __libc_pthread_init,
which is defined in libc.so.6 and called from libpthread.so.0.

commit 0edbf1230131dfeb03d843d2859e2104456fad80
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Tue Jan 31 18:01:59 2017 -0200
nptl: Invert the mmap/mprotect logic on allocated stacks (BZ#18988)
Current allocate_stack logic for create stacks is to first mmap all
the required memory with the desirable memory and then mprotect the
guard area with PROT_NONE if required. Although it works as expected,
it pessimizes the allocation because it requires the kernel to actually
increase commit charge (it counts against the available physical/swap
memory available for the system).
The only issue is to actually check this change since side-effects are
really Linux specific and to actually account them it would require a
kernel specific tests to parse the system wide information. On the kernel
I checked /proc/self/statm does not show any meaningful difference for
vmm and/or rss before and after thread creation. I could only see
really meaningful information checking on system wide /proc/meminfo
between thread creation: MemFree, MemAvailable, and Committed_AS shows
large difference without the patch. I think trying to use these
kind of information on a testcase is fragile.
The BZ#18988 reports shows that the commit pages are easily seen with
mlockall (MCL_FUTURE) (with lock all pages that become mapped in the
process) however a more straighfoward testcase shows that pthread_create
could be faster using this patch:
--
static const int inner_count = 256;
static const int outer_count = 128;
static
void *thread1(void *arg)
{
return NULL;
}
static
void *sleeper(void *arg)
{
pthread_t ts[inner_count];
for (int i = 0; i < inner_count; i++)
pthread_create (&ts[i], &a, thread1, NULL);
for (int i = 0; i < inner_count; i++)
pthread_join (ts[i], NULL);
return NULL;
}
int main(void)
{
pthread_attr_init(&a);
pthread_attr_setguardsize(&a, 1<<20);
pthread_attr_setstacksize(&a, 1134592);
pthread_t ts[outer_count];
for (int i = 0; i < outer_count; i++)
pthread_create(&ts[i], &a, sleeper, NULL);
for (int i = 0; i < outer_count; i++)
pthread_join(ts[i], NULL);
assert(r == 0);
}
return 0;
}
--
On x86_64 (4.4.0-45-generic, gcc 5.4.0) running the small benchtests
I see:
$ time ./test
real 0m3.647s
user 0m0.080s
sys 0m11.836s
While with the patch I see:
$ time ./test
real 0m0.696s
user 0m0.040s
sys 0m1.152s
So I added a pthread_create benchtest (thread_create) which check
the thread creation latency. As for the simple benchtests, I saw
improvements in thread creation on all architectures I tested the
change.
Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
arm-linux-gnueabihf, powerpc64le-linux-gnu, sparc64-linux-gnu,
and sparcv9-linux-gnu.
[BZ #18988]
* benchtests/thread_create-inputs: New file.
* benchtests/thread_create-source.c: Likewise.
* support/xpthread_attr_setguardsize.c: Likewise.
* support/Makefile (libsupport-routines): Add
xpthread_attr_setguardsize object.
* support/xthread.h: Add xpthread_attr_setguardsize prototype.
* benchtests/Makefile (bench-pthread): Add thread_create.
* nptl/allocatestack.c (allocate_stack): Call mmap with PROT_NONE and
then mprotect the required area.

Fixed by 0edbf1230131dfeb03d843d2859e2104456fad80. Using a slight modified
version of the program described in commend #1 with a stack size adjustment set
to an arbitrary value (in this case 1134592) since musl default stack size is
lower to GLIBC one (and thus it issue a PROT_NONE call with a smaller value), I
see on my x86_64 system (4.4.0-71-generic):
$ sudo ./test-musl
memory before threads
MemAvailable: 10762536 kB
memory after threads
MemAvailable: 9627732 kB
$ sudo ./testrun.sh ./test-glibc
memory before threads
MemAvailable: 10761076 kB
memory after threads
MemAvailable: 10656640 kB
GLIBC it now showing a slight better result regarding RSS usage.

I was trying to compile the glibc-2.25 with disabled FUTEX_CLOCK_REALTIME
feature.

I have found, that was missing '_' between 'lll_futex_timed' and 'wait'.
Proposal patch is included in attachment.

--- Comment #1 from Carlos O'Donell <carlos at redhat dot com> ---
Andrej,
Thanks for the bug report!
It is dangerous to compile glibc-2.25 with FUTEX_CLOCK_REALTIME disabled, the
expectation in 2.25 is that you always have a new enough kernel that has this
feature (linux 2.6.32 for x86_64/x86 or higher if other arches), which is why
it is unconditionally defined in kernel-features.h.
Are you compiling glibc 2.25 for kernels older than linux 2.6.32? If that's the
case then you need to stay with older glibc or discuss upstream
(libc-alpha@sourceware.org) the need to keep newer glibc building for older
kernels.
The correct fix is to remove all code that is added back with !defined
__ASSUME_FUTEX_CLOCK_REALTIME. This way we simplify the codebase down to just
supporting the newer kernels which all have FUTEX_CLOCK_REALTIME (since linux
2.6.29).
Unfortunately such a patch exceeds the 15 lines we might be able to accept from
Siemens without a copyright assignment. Would you consider a future copyright
assignment so we could start accepting patches form Siemens to cleanup these
issues?

--- Comment #2 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
The !__ASSUME_FUTEX_CLOCK_REALTIME case would I suppose have been
theoretically live for the NaCl port before that was removed. Yes,
conditionals on __ASSUME_FUTEX_CLOCK_REALTIME (and the definition) should
now be removed throughout the tree.
I'm doubtful that such a mechanical removal is actually legally
significant for copyright purposes. (To quote maintain.texi, "A regular
series of repeated changes, such as renaming a symbol, is not legally
significant even if the symbol has to be renamed in many places.".)

proposal patch V2 to fix "unknown type name 'lll_futex_timed'"
Some words for introduction into problematic.
I have a legacy java JVM, which can not be rebuild with new gblic (I have only
a binary). My application uses this JVM binary for Thread.sleep method calling
to wait some time. The main idea was to have waiting in thread time
independent. From the strace analysis/debugging have found, that binary uses
semaphores for waiting. The main problem is, that the semaphores uses
CLOCK_REALTIME as clock source.
My java application was working well with glibc_2.11 . Now, I have upgraded the
glibc to version 2.23 and it has stopped working. So I have created
C-application for testing (which I have had under control). The application
uses CLOCK_MONOTONIC and CLOCK_REALTIME as selective clock sources. So I could
compare the time spared by waiting. I was changing a system time over 'date'
command back and forward. Time spared by waiting had to be equal with the set
timeout.
C-app
- glibc_2.11 and 2.20
- MONO and REAL was not influenced by system time changing
- glibc_2.23
- MONO same as 2.11 and 2.20
- REAL - was influenced by system time changing what is correct
Java-app
- only glibc_2.11 was time independent
So I was trying to make some workaround, how to solve the problem without JVM
binary changing. I have undefined __ASSUME_FUTEX_CLOCK_REALTIME . Now the java
uses lll_futex_timed_wait function not the lll_futex_timed_wait_bitset, where
is FUTEX_CLOCK_REALTIME as default.
I don't know, if this is a right solution. I didn't want to add some "ugly"
callers checking or something else into the glibc.
And now, I was trying to make same thing in 2.25.

// The roundup macro from /usr/include/sys/param.h (misc/sys/param.h in
// git repository) produce different results in the GCC and non-GCC
// versions for some input. This is why I would consider this a bug.
// Also only the fast path of the macro contains the "bug" so it
// will produce different results based on if y is a constant or not.
// Compile this program using:
// gcc -std=c99 -O2 -Wall -g -o roundup_glibc_bug roundup_glibc_bug.c
/*
Code block in sys/param.h looks like this:
#ifdef __GNUC__
# define roundup(x, y) (__builtin_constant_p (y) && powerof2 (y) \
? (((x) + (y) - 1) & ~((y) - 1)) \
: ((((x) + ((y) - 1)) / (y)) * (y)))
#else
# define roundup(x, y) ((((x) + ((y) - 1)) / (y)) * (y))
#endif
*/
// Both macros has been made available with _gcc and _non_gcc postfix to
// be able to illustrate the issue.
# define roundup_gcc(x, y) (__builtin_constant_p (y) && powerof2 (y) \
? (((x) + (y) - 1) & ~((y) - 1)) \

--- Comment #8 from Romain Geissler <romain.geissler at amadeus dot com> ---
Hi,
Sorry for digging into this old bug report, but we have just noticed we were
also affected after a glibc/gcc upgrade.
Jason Merrill has described the rational behind GNU unique symbols in
https://www.sourceware.org/ml/libc-alpha/2002-05/msg00222.html, and indeed the
introduction of this GNU extension makes sense.
Yet what I don't understand is the piece of code that does flag a dlopen'ed
library as NODELETE if one relocation is resolve into this library. In current
trunk it is here:
https://sourceware.org/git/?p=glibc.git;a=blob;f=elf/dl-lookup.c;h=3d2369dbf2b7ca219eaf80a820e2a8e1329fbf50;hb=92bd70fb85bce57ac47ba5d8af008736832c955a#l332
In this old 2002 post, Jason mentions solution #1 and #2, both of them being
needed to work well.
#1 is "Always prefer the last weak definition if no strong definition is
seen.". From what I see here:
https://sourceware.org/git/?p=glibc.git;a=blob;f=elf/dl-lookup.c;h=3d2369dbf2b7ca219eaf80a820e2a8e1329fbf50;hb=92bd70fb85bce57ac47ba5d8af008736832c955a#l526
this is already the case in the trunk for years (at least this is the comment
says, I am not sure this is what is really implemented).
#2 is "If a DSO A has two unrelated dependencies B and C which both define (and
use) the same weak symbol, add C to the dependency list of this loaded
copy of B."
Isn't this the point of "add_dependency" called here
https://sourceware.org/git/?p=glibc.git;a=blob;f=elf/dl-lookup.c;h=3d2369dbf2b7ca219eaf80a820e2a8e1329fbf50;hb=92bd70fb85bce57ac47ba5d8af008736832c955a#l929
after the call to "do_lookup_x" which handles unique symbols in a specific way
?
My point is, unique symbols do create some bindings between libraries that
normally should not be bound together. I am fine with that. However if I do
unload all these dlopen'ed library, I would expect all dynamically dependencies
added between the two RTLD_LOCAL object to be removed, and eventually all the
libraries to be fully unloaded (with static destructor called). I am fine with
"dlclose" not closing the library if another dlopened library has some symbols
resolved into the first one, but then a second call to "dlclose" on the second
library should unload both libraries.
So am I right thinking that marking libraries where unique relocation are
resolved to as NODELETE is wrong ? All the mechanism is already there to
properly handle the closing of libraries at the right time thanks to
"add_dependency", isn't it ?
Cheers,
Romain

Bug ID: 21604
Summary: glibc fails to build with a gcc/musl toolchain
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: sam.thursfield at codethink dot co.uk
CC: drepper.fsp at gmail dot com
Target Milestone: ---
I get a build failure in the sunrpc/ subdirectory when building GLIBC on Alpine
Linux 3.6.1.
The toolchain has a target of `x86_64-alpine-linux-musl` so it's perhaps not
officially supported by GLIBC. However this issue is the only thing that
prevents GLIBC 2.25 from compiling in that environment so it would be
worthwhile to fix it.
musl libc defines certain types in its sys/types.h when _GNU_SOURCE or
_BSD_SOURCE is set, such as `u_char`, `u_short`, and `caddr_t`.
See: http://git.musl-libc.org/cgit/musl/tree/include/sys/types.h#n59
These are redefined inside GLIBC in `sunrpc/rpc/types.h`, causing 'conflicting
types' issues.
If GLIBC could detect the existance of these symbols at configure-time in the
host libc it could then #ifdef away the redefinitions appropriately.
This is the full error output:
gcc -D_RPC_THREAD_SAFE_ -D_GNU_SOURCE -DIS_IN_build -include

A call to strtol returns a value that depends only on the values of its
arguments (and the global locale). As a result, consecutive calls to the
function with the same arguments and no intervening call to setlocale can be
folded into one. The test case below shows that when using Glibc, GCC doesn't
take advantage of this optimization opportunity. The test case also shows that
decorating strtoul with attribute pure lets GCC perform this transformation.
$ cat t.c && gcc -O2 -S -Wall -Wextra -Wpedantic
-fdump-tree-optimized=/dev/stdout t.c
#include <stdlib.h>
long f (const char *s)
{
char *e;
long i = strtol (s, &e, 0);
long j = strtol (s, &e, 0); // call can be replaced with i
return i + j;
}
extern unsigned long
strtoul (const char* restrict, char **restrict, int) __attribute__ ((pure));
unsigned long g (const char *s)
{
char *e;
unsigned long i = strtoul (s, &e, 0);
unsigned long j = strtoul (s, &e, 0); // call replaced with i
return i + j;
}
;; Function f (f, funcdef_no=10, decl_uid=2379, cgraph_uid=10, symbol_order=10)
f (const char * s)
{
long int j;
long int i;
char * e;
long int _7;
<bb 2> [100.00%] [count: INV]:
i_4 = strtol (s_2(D), &e, 0);
j_6 = strtol (s_2(D), &e, 0);
_7 = i_4 + j_6;
e ={v} {CLOBBER};
return _7;
}
;; Function g (g, funcdef_no=11, decl_uid=2389, cgraph_uid=11, symbol_order=11)
g (const char * s)
{
long unsigned int i;
char * e;
long unsigned int _4;
<bb 2> [100.00%] [count: INV]:
i_3 = strtoul (s_2(D), &e, 0);
_4 = i_3 * 2;
e ={v} {CLOBBER};
return _4;

Hack to fix compilation with musl (but breaking things for all other
toolchains)
Here's a patch which allows GLIBC to be compiled with an
x86_64-alpine-linux-musl toolchain. It makes no attempt at maintaining
compatibility with other toolchains so should definitely NOT be merged into
glibc.

strtol is specified to set errno to ERANGE on overflow, which means it is not
pure.

--- Comment #2 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
Some fixes for OS X and FreeBSD build systems were made in commit
ae7080d30c68cfa0c81ce3422dca948f64a94f50; I suppose that could be a guide to
fixing this. If libtirpc has its own rpcgen / librpcsvc another option would
be to phase out support for building then in glibc at all.

Since/when errno is a function, testing it between the successive calls would
disable the optimization. What would a test case that would expose this as a
problem?

--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
#include <errno.h>
extern void abort (void);
extern unsigned long
strtoul (const char* restrict, char **restrict, int) __attribute__ ((pure));
int
main (void)
{
errno = 0;
(void) strtoul ("99999999999999999999", (char **) 0, 0);
if (errno != ERANGE)
abort ();
return 0;
}
In this case, with strtoul marked as pure, the call gets completely
removed, but removing it is wrong because of the required side effect of
setting errno to ERANGE.

(And, since __errno_location is marked const, I don't think calls to it,
and read accesses to the memory location to which it returns a pointer,
should prevent multiple calls to a pure function from being collapsed into
one.)

--- Comment #5 from Martin Sebor <msebor at gmail dot com> ---
Thanks. The only thing I could think of was something like:
int i = strtol (s, 0, 0);
int *perr = &errno;
int j = strtol (s, 0, 0);
if (*perr) abort ();
but I'm not sure accessing errno like this is meant to be valid (though it
wouldn't terribly surprise me if code like that did exist).
POSIX also specifies that "the value of errno should only be examined when it
is indicated to be valid by a function’s return value" but, unfortunately, it's
not a hard requirement and C doesn't say anything like that.
It's too bad that it can't be done. Since these examples are likely rare
corner cases it might be worth seeing if the specs (i.e., C2X and POSIX) could
be tightened up to allow it.

Add private_function for private functions within glibc
Shadow Stack in Intel Control-flow Enforcement Technology (CET)
instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
doesn't support _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

i386: Update _dl_runtime_resolve/_dl_runtime_profile
To make symbol resolver compatible with Shadow Stack in Intel Control-flow
Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
call resolved function indirectly with %ecx.
[BZ #21598]
* sysdeps/i386/dl-trampoline.S (_dl_runtime_resolve): Call
resolved function indirectly with %ecx.
(_dl_runtime_profile): Likewise.

commit 32604815347b5316e46d481c2967bd526410a2c8
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Fri Jun 16 14:27:02 2017 -0700
Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

Bug ID: 21607
Summary: hppa: FAIL: math/test-tgmath
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: danglin at gcc dot gnu.org
CC: zackw at panix dot com
Target Milestone: ---
Host: hppa-unknown-linux-gnu
Target: hppa-unknown-linux-gnu
Build: hppa-unknown-linux-gnu
The test-tgmath test now fails on hppa with following output:
dave@mx3210:~/gnu/glibc/objdir/math$ cat test-tgmath.out
double function called for long double test
long double functions not called often enough (0)
long double complex functions not called often enough (0)
Long double and double are the same on hppa-linux. The long double
tests didn't used to run in this test because of the NO_LONG_DOUBLE
conditionals. However, this change overrides the -DNO_LONG_DOUBLE
definition in the compile command and the test now fails:
2017-05-11 Zack Weinberg <zackw@panix.com>
* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
very top of the file and rationalize their order.
If MODULE_NAME is not defined at all, define IS_IN to always be
false, and don't define _ISOMAC.
If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
true, define _ISOMAC and suppress everything else in this file,
starting with the inclusion of config.h.
Do check for inappropriate definitions of __OPTIMIZE__ and
__FAST_MATH__ here, but only if _ISOMAC is not defined.
Correct some out-of-date commentary.
* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
and _Mlong_double_ before including math.h.
Similar fail: test-tgmath2.

--- Comment #1 from John David Anglin <danglin at gcc dot gnu.org> ---
The following fails are also probably related:
FAIL: math/basic-test
FAIL: math/test-double-canonicalize
FAIL: math/test-float-canonicalize
FAIL: math/test-idouble-canonicalize
FAIL: math/test-ifloat-canonicalize
The basic-test fail is related to the treatment of signaling nans during
conversion:
dave@mx3210:~/gnu/glibc/objdir/math$ cat basic-test.out
Failure: double x = (double) (long double) sNaN, !issignaling
Failure: long double x = (long double) (double) sNaN, !issignaling
I filed a gcc bug report:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81120
However, as noted in the above, there are subtle issues involving the
conversion
of signaling nans.

Target Milestone: ---
Due to a gcc bug (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066), there
are binaries¹ in the wild² that call __tls_get_addr() with an improperly
aligned stack. They will crash if anything in the subsequent call chain uses
e.g. MOVAPS to store to the stack.
__tls_get_addr() should be annotated with
__attribute__((force_align_arg_pointer)) on x86-64 to avoid this bug.

Bug ID: 21609
Summary: Incomplete workaround for GCC __tls_get_addr ABI issue
on x86-64
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Target: x86-64
In bug 15128, glibc added some code to compensate for an invalid calling
sequence of the __tls_get_addr function generated by GCC for old binaries.
However, this code only works around issues caused by the GCC ABI violation
within the dynamic linker. It does not protect __tls_get_addr itself. With
recent GCC enhancements, __tls_get_addr and the code it calls (notably malloc)
need stack realignment as well.

Note that patch does not work because we are not ready to move the GCC
requirement to a version which supports force_align_arg_pointer on x86-64.

commit 5e5b3b886635b52d9baa87414b97965190035e46
Author: Stefan Liebler <stli@linux.vnet.ibm.com>
Date: Mon Jun 19 11:06:49 2017 +0200
S390: Fix build with gcc configured with --enable-default-pie. [BZ #21537]
Building glibc with gcc configured with --enable-default-pie failed on s390
due to assembler messages:
../sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S:44:
Error: junk at end of line, first unrecognized character is `@'
HIDDEN_JUMPTARGET was expanded to exit@PLT@GOTOFF.
If SHARED is not defined, HIDDEN_JUMPTARGET is defined to JUMPTARGET
in sysdeps/s390/s390-32/sysdep.h. There it expanded to exit@PLT
in non SHARED case as PIC is defined if gcc is configured with
--enable-default-pie. Thus I've changed the "ifdef PIC" to "ifdef SHARED"
as we do not want PLTs in the static obj files. I've also changed this
in sysdeps/s390/s390-64/sysdep.h.
I've also adjusted
sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S.
If glibc is configured with --disable-hidden-plt, then NO_HIDDEN is
defined.
In SHARED case HIDDEN_JUMPTARGET would be expanded to exit@PLT@GOTOFF
instead of __GI_exit@GOTOFF.
Now we jump to:
- __GI_exit if SHARED is defined
- exit@PLT if SHARED and NO_HIDDEN is defined
- exit if both are not defined.
On s390 31bit we have to setup GOT pointer in r12 if we use a PLT stub.
Therefore I use SYSCALL_PIC_SETUP from sysdep.h and added the missing
semicolons.
ChangeLog:
[BZ #21537]
* sysdeps/s390/s390-32/sysdep.h (JUMPTARGET, SYSCALL_PIC_SETUP):
Check SHARED instead of PIC.
(SYSCALL_PIC_SETUP): Add missing semicolons.
* sysdeps/s390/s390-64/sysdep.h (JUMPTARGET, SYSCALL_PIC_SETUP):
Check SHARED instead of PIC.
* sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S
(__makecontext_ret): Adjust code to jump to exit.

commit a66bc30d6b19ca6c9c77c0d3750acb18c691705f
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jun 19 11:59:19 2017 +0000
Define struct rusage in sys/wait.h when required (bug 21575).
Some older standards (XPG4.2 through POSIX.1:2001, XSI only) require
sys/wait.h to include the definition of struct rusage. This is
missing in glibc.
This patch adds the required definition. struct rusage is moved to a
new header bits/types/struct_rusage.h to avoid bringing in the whole
of sys/resource.h (although the standards in question do allow the
whole of sys/resource.h to be brought in). In the five
bits/resource.h headers, the only variation between the definitions of
struct rusage is that the sysdeps/unix/sysv/linux version is prepared
for x32 (by having anonymous unions with __syscall_slong_t fields) and
the others are not. Thus, this version is suitable for use
generically (everything other than x32 simply has __syscall_slong_t
the same as long int, so there are no API or ABI changes involved, and
anonymous unions are already a required language feature for glibc
headers elsewhere), and this patch uses it as a base for the single
implementation of bits/types/struct_rusage.h.
Tested for x86_64, and with build-many-glibcs.py.

Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jun 19 12:00:13 2017 +0000
Fix signal stack namespace (bug 21584).
In POSIX.1:2008, various signal stack symbols - sigaltstack, SS_*,
SIGSTKSZ, MINSIGSTKSZ - are all XSI-shaded. glibc wrongly makes them
visible for non-XSI POSIX. This patch fixes the conditionals, leaving
the symbols available for __USE_MISC as it seems likely some of them
are widely used and should be visible by default. (Note that stack_t
is *not* XSI-shaded and so the conditionals on that are correctly
unchanged.)
Tested for x86_64.
[BZ #21584]
* signal/signal.h: Make includes of <bits/sigstack.h> and
<bits/ss_flags.h> conditional on [__USE_XOPEN_EXTENDED ||
__USE_MISC].
(sigaltstack): Make declaration conditional on
[__USE_XOPEN_EXTENDED || __USE_MISC].

--- Comment #7 from Phil Blundell <pb at pbcl dot net> ---
I think the bug is in gai_suspend(), here:
/* Now remove the entry in the waiting list for all requests
which didn't terminate. */
for (cnt = 0; cnt < ent; ++cnt)
if (list[cnt] != NULL && list[cnt]->__return == EAI_INPROGRESS
&& requestlist[cnt] != NULL)
{
struct waitlist **listp = &requestlist[cnt]->waiting;
/* There is the chance that we cannot find our entry anymore.
This could happen if the request terminated and restarted
again. */
while (*listp != NULL && *listp != &waitlist[cnt])
listp = &(*listp)->next;
if (*listp != NULL)
*listp = (*listp)->next;
}
The check for (list[cnt]->__return == EAI_INPROGRESS) here is incorrect because
handle_request() may have assigned a new return value while we were sleeping
(or in fact at any other time, since this particular operation in
handle_request() is not guarded by __gai_requests_mutex).
I think the fix is probably to remove that condition and allow the loop to
search all lists for an entry that we added.

Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jun 19 12:18:46 2017 +0000
Fix siginterrupt namespace (bug 21597).
The siginterrupt function is XSI-shaded in POSIX. glibc wrongly
declares it in <signal.h> for non-XSI POSIX.1:2008. This patch fixes
the conditionals (moving it into the __USE_XOPEN_EXTENDED ||
__USE_MISC block as the minimum conservative change, although it's not
clear this obsolescent function should be declared by default).
Tested for x86_64.
[BZ #21597]
* signal/signal.h (siginterrupt): Make declaration conditional on
[__USE_XOPEN_EXTENDED || __USE_MISC].

commit 4bb38ff950ccbf3c2449a7f5314e860098e51da6
Author: H.J. Lu <hjl.tools@gmail.com>

x86-64: Implement strcmp family IFUNC selectors in C
Implement strcmp family IFUNC selectors in C and enable SSE4.2/AVX
strcmp/strncmp.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcmp family functions within libc.

S390: Sync ptrace.h with kernel. [BZ #21539]
This patch removes PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS
and PTRACE_SETFPREGS as these requests does not exist on s390 kernel.
But the kernel has support for PTRACE_SINGLEBLOCK,
PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA,
PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE and
PTRACE_TE_ABORT_RAND. Thus those are defined now.
The current kernel s390 specific ptrace.h file also defines
PTRACE_PEEKTEXT_AREA, PTRACE_PEEKDATA_AREA, PTRACE_POKETEXT_AREA,
PTRACE_POKEDATA_AREA, PTRACE_PEEK_SYSTEM_CALL, PTRACE_POKE_SYSTEM_CALL
and PTRACE_PROT, but those requests are not supported.
Thus those defines are skipped in glibc ptrace.h.
There were old includes of ptrace.h in sysdeps/s390/fpu/fesetenv.c.
The ptrace feature isn't used there anymore, thus I removed the includes.
Before this patch, <glibc>/sysdeps/unix/sysv/linux/s390/sys/ptrace.h
uses ptrace-request 12 for PTRACE_GETREGS,
but <kernel>/include/uapi/linux/ptrace.h uses 12 for PTRACE_SINGLEBLOCK.
The s390 kernel has never had support for PTRACE_GETREGS!
Thus glibc ptrace.h is adjusted to match kernel ptrace.h.
The new s390 specific test ensures, that PTRACE_SINGLEBLOCK defined
in glibc works as expected. If the kernel would interpret it as
PTRACE_GETREGS, then the testcase will not make any progress
and will time out.
ChangeLog:
[BZ #21539]
* NEWS: Mention s390 ptrace request changes.
* sysdeps/unix/sysv/linux/s390/sys/ptrace.h
(PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS,
PTRACE_SETFPREGS): Remove enum constant.
(PT_GETREGS, PT_SETREGS, PT_GETFPREGS, T_SETFPREGS):
Remove defines.
(PTRACE_SINGLEBLOCK): New enum constant.
(PT_STEPBLOCK): New define.
(PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA,
PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE,
PTRACE_TE_ABORT_RAND): New enum constant and define.
* sysdeps/s390/fpu/fesetenv.c: Remove ptrace.h includes.
* sysdeps/unix/sysv/linux/s390/tst-ptrace-singleblock.c:
New file.
* sysdeps/unix/sysv/linux/s390/Makefile: Add test.

commit 273bf3030e363f249347c2266ead51bb731f1246
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Mon Jun 12 17:08:44 2017 -0700
x86-64: Implement strcmp family IFUNC selectors in C
Implement strcmp family IFUNC selectors in C.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcmp family functions within libc.
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
strcmp-sse2, strcmp-sse4_2, strncmp-sse2, strncmp-sse4_2,
strcasecmp_l-sse2, strcasecmp_l-sse4_2, strcasecmp_l-avx,
strncase_l-sse2, strncase_l-sse4_2 and strncase_l-avx.
* sysdeps/x86_64/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Add tests for __strcmp_avx and
__strncmp_avx.

Bug ID: 21622
Summary: [tile] missing SA_* for POSIX.1:2008
Product: glibc

Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
As shown by conform/ tests once the remaining namespace issues are fixed, the
tile bits/sigaction.h fails to declare SA_RESETHAND, SA_RESTART and SA_NODEFER
for non-XSI POSIX.1:2008 as other versions do. Those constants were moved from
XSI to Base in the 2008 edition of POSIX.

--- Comment #2 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
If a test actually depends on long double and double being different, then
it should test e.g. LDBL_MANT_DIG > DBL_MANT_DIG. If, however, the
conditional is just a legacy of when long double functions weren't
declared in tests, it should be removed.
tgmath and basic-test are cases where the test actually has a dependency.
(For the sNaN issues, a conversion to same format may be either a
convertFormat or a copy operation, so it's not specified whether it quiets
sNaNs to convert long double to same-format double.)

--- Comment #3 from Zack Weinberg <zackw at panix dot com> ---
FYI, I mean to look into this in more detail tomorrow or Wednesday - I'm on a
deadline for $dayjob right now.
Undefining NO_LONG_DOUBLE when _ISOMAC was necessary in order to make certain
tests on certain platforms compile at all, but I don't remember any more
details than that; I'm going to have to reconstruct the problem.

CVE-2017-1000366: Ignore LD_LIBRARY_PATH for AT_SECURE=1 programs [BZ
#21624]
LD_LIBRARY_PATH can only be used to reorder system search paths, which
is not useful functionality.
This makes an exploitable unbounded alloca in _dl_init_paths unreachable
for AT_SECURE=1 programs.

commit bf15120dd7860ac976f22e20fa386d8bf73c70e7
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jun 19 16:39:17 2017 +0000
Fix wait3 namespace (bug 21625).
The wait3 function was removed in the 2001 edition of POSIX.
sys/wait.h wrongly declares it for the 2001 and 2008 editions of POSIX
when XSI features are enabled. This patch fixes the conditionals.
Tested for x86_64.
[BZ #21625]
* posix/sys/wait.h (strust rusage forward declaration): Change
[__USE_XOPEN_EXTENDED] conditional to [__USE_XOPEN_EXTENDED &&
!__USE_XOPEN2K].
(wait3): Likewise.

commit 3776f38fcd267c127ba5eb222e2c614c191744aa
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Tue Jun 20 05:59:17 2017 +0200
Ignore and remove LD_HWCAP_MASK for AT_SECURE programs (bug #21209)
The LD_HWCAP_MASK environment variable may alter the selection of
function variants for some architectures. For AT_SECURE process it
means that if an outdated routine has a bug that would otherwise not
affect newer platforms by default, LD_HWCAP_MASK will allow that bug
to be exploited.
To be on the safe side, ignore and disable LD_HWCAP_MASK for setuid
binaries.
[BZ #21209]
* elf/rtld.c (process_envvars): Ignore LD_HWCAP_MASK for
AT_SECURE processes.
* sysdeps/generic/unsecvars.h: Add LD_HWCAP_MASK.
* elf/tst-env-setuid.c (test_parent): Test LD_HWCAP_MASK.
(test_child): Likewise.
* elf/Makefile (tst-env-setuid-ENV): Add LD_HWCAP_MASK.

commit 0578ef88fd6ea9bd0039ab8cbcbc9a964e3b9969
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Tue Jun 20 06:05:02 2017 +0200
Ignore and remove LD_HWCAP_MASK for AT_SECURE programs (bug #21209)
The LD_HWCAP_MASK environment variable may alter the selection of
function variants for some architectures. For AT_SECURE process it
means that if an outdated routine has a bug that would otherwise not
affect newer platforms by default, LD_HWCAP_MASK will allow that bug
to be exploited.
To be on the safe side, ignore and disable LD_HWCAP_MASK for setuid
binaries.
[BZ #21209]
* elf/rtld.c (process_envvars): Ignore LD_HWCAP_MASK for
AT_SECURE processes.
* sysdeps/generic/unsecvars.h: Add LD_HWCAP_MASK.
(cherry picked from commit 1c1243b6fc33c029488add276e56570a07803bfd)

conformtest: XFAIL uc_sigmask test for ia64 (bug 21634).
This patch XFAILs one test where the ia64 ucontext_t has the wrong
type of a field, to allow the conform/ tests as a whole to pass once
the namespace issues are fixed.
Tested with build-many-glibcs.py.

(conformtest-xfail-conds): New variable.
* conform/data/signal.h-data (uc_sigmask): XFAIL for ia64-linux.
* conform/data/ucontext.h-data (uc_sigmask): Likewise.

--- Comment #4 from Zack Weinberg <zackw at panix dot com> ---
I can no longer reproduce any problem with leaving NO_LONG_DOUBLE_MATH defined
when _ISOMAC is defined, in a build-many-glibcs cycle (with the hppa patches
you sent me a couple weeks ago applied). So, if that seems to be the most
expeditious way to solve the problem, I have no objection to your removing that
line from include/math.h. I'd prefer that you make the change after confirming
it solves the problem for you, though.

I'm not sure if it is technically feasible to support dlopen from
dl_iterate_phdr because this will change the set of loaded shared objects while
enumerating them.

Summary: Incorrect pointer alignment in NSS group merge result
construction
Product: glibc

Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com

Flags: security-
Sergey Kolosov discovered that the NSS group merge feature does not work on
ppc64 and s390x. The cause seems to be this code in grp/grp-merge.c:
/* Copy the pointers from the members array into the buffer and assign them
to the gr_mem member of destgrp. */
destgrp->gr_mem = (char **) &destbuf[c];
len = sizeof (char *) * (memcount + 1);
BUFCHECK (len);
memcpy (&destbuf[c], members, len);
c += len;
free (members);
members = NULL;
After the assigned to destgrp->gr_mem, we have:
(gdb) print destbuf
$1 = 0x10031000 "groupa"
(gdb) print c
$2 = 21
(gdb) print destgrp->gr_mem
$3 = (char **) 0x10031015
This pointer is not suitable aligned, and this triggers undefined behavior.
We should switch this code over to the allocation buffer interface, which deals
with exactly this kind of problem.

DJ's new NSS tests will probably catch this on s390/ppc because they explicitly
test the MERGE functionality. I guess we'll have to fix this before DJ's tests
can go into master.

My preference would still be to avoid NO_LONG_DOUBLE in tests, testing
LDBL_MANT_DIG if such a conditional is needed, or removing the conditional
if not needed.

commit 9649350d2ee47fae00794d57e2526aa5d67d900e
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Jun 21 17:35:24 2017 +0000
Fix tile SA_* conditions for POSIX.1:2008 (bug 21622).
As shown by conform/ tests once the remaining namespace issues are
fixed, the tile bits/sigaction.h fails to declare SA_RESETHAND,
SA_RESTART and SA_NODEFER for non-XSI POSIX.1:2008 as other versions
do. Those constants were moved from XSI to Base in the 2008 edition
of POSIX. This patch fixes the conditions to match other versions of
this header.
Tested (compilation only) for tilegx-linux-gnu with
build-many-glibcs.py.
[BZ #21622]
* sysdeps/unix/sysv/linux/tile/bits/sigaction.h (SA_RESTART):
Define for [__USE_UNIX98 || __USE_XOPEN2K8], not [__USE_UNIX98 ||
__USE_MISC].
(SA_NODEFER): Likewise.
(SA_RESETHAND): Likewise.

Removing the NO_LONG_DOUBLE undef fixes the test regressions but I agree with
Joseph. The tests need to be fixed.

I don't think ENOENT should trigger the fallback, since we already know that
/tmp does not exist.

That test is better. However, the test is not guaranteed to terminate because
C would consume the signal that both B and C are allowed to consume.
Furthermore, I know what you're trying to do with the sleep in the signal
handler, but is sleep() actually allowed in a handler?

This execution should not happen. B and C consume the two signals (C doesn't
time out), but A should be woken in any case.

Please do test it with a current version of glibc. This behavior (ie, that
more recent waiting threads could "steal" a signal from earlier waiting
threads) is exactly why we needed a new condvar algorithm.

[PATCH] Parse interface zone id for node-local multicast
I stumbled upon programs not able to send to an interface-local multicast
address; at first, it was because Linux kernel since 3.10 (see
842df0739776fc9af7ac15968b44415a31ba9be4) *requires* a zone id for
interface-local multicast addresses, while I thought it did not (I think there
is some confusion here, as they are often qualified “node-localâ€, which seems
to imply they do not need scope qualification). But then, currently, glibc does
not parse interface names to zone id (sometimes called “scope id†too) for
interface-local multicast addresses, so they are a bit difficult to use; e.g.:
$ ping6 ff01::1%lo
unknown host
$ ping6 ff01::1%1
PING ff01::1%1(ff01::1) 56 data bytes
64 bytes from ::1: icmp_seq=1 ttl=64 time=0.018 ms
^C
The attached patch proposes to allow it. Proposed commit message following.

> echo -en '\x80' | iconv -f us-ascii -t us-ascii//translit//ignore -c
> echo -en "\x0e\x0e" | /usr/bin/iconv -c -f IBM1364
I have not investigated the second reproducer, but I am quite sure that it is
completely unrelated to the first one.
The first one is caused by incorrect parsing of the "//" marked suffixes
(//translit and //ignore). The problem is that the second suffix is being
dropped when parsing. This is why the order matters. The case reported, i.e.:
$ echo -en '\x80' | iconv -f us-ascii -t us-ascii//translit//ignore -c
is one where the "//translit" suffix is actually irrelevant because the input
does not have characters that can/should be transliterated, but its presence as
the first suffix leads to the actually relevant "//ignore" suffix (0x80 is not
valid ASCII) being *ignored* by iconv, leading to a hang.
This is why, these four similar cases:
$ echo -en '\x80' | iconv -f us-ascii -t us-ascii//ignore//translit -c
$ echo -en '\x80' | iconv -f us-ascii -t us-ascii//ignore -c
$ echo -en '\x80' | iconv -f us-ascii -t us-ascii -c
$ echo -en '\x80' | iconv -f us-ascii -t us-ascii//translit -c
do not hang. The '//ignore' suffix being first (or implied via -c) gets picked
up by the program and it correctly outputs nothing, and the "//translit", if
present, is dropped (incorrectly) - but this has no effect for this particular
input on the program's running because like I mentioned earlier: there is
nothing to be transliterated in the input. Note that '-c' actually appends the
"//ignore" to the target encoding suffix if no suffixes are present, and
",ignore" if one or more suffixes are already present. If two suffixes are
passed during input, then the ',ignore' appended because of '-c' will get
dropped along with the second suffix, which may or may not lead to hang
depending on whether the first suffix is //ignore.
The hang in case of a missing "//ignore" suffix (well, not really missing here
but ignored by the program) afterwards during execution is a separate problem
(that I haven't investigated).
I'm going to write a patch to fix the problem with the parsing at the right
place(s), and then tackle the hangs separately.

--- Comment #12 from Arjun Shankar <arjun.is at lostca dot se> ---
I quickly want to point out that passing an input character that requires
transliteration and then passing //translit as the second suffix also leads to
erroneous program behaviour (it reports an error instead of performing
transliteration). Some test cases:
Exits successfully with 'A' written to stdout (because //translit is the only
or first suffix):
$ echo -en '\xc3\x81' | iconv -f utf8 -t "us-ascii//translit"
$ echo -en '\xc3\x81' | iconv -f utf8 -t "us-ascii//translit//ignore"
No transliteration and corresponding "illegal input sequence" error thrown,
even though //translit is passed, but it is incorrectly ignored by the program
because it is not the first suffix:
$ echo -en '\xc3\x81' | iconv -f utf8 -t "us-ascii//ignore//translit"
Exits without error messages but (incorrectly) writes nothing to stdout. This
is because 'translit' got ignored (2nd suffix), but '-c' leads to silently
dropping the input character that wasn't transliterated:
$ echo -en '\xc3\x81' | iconv -f utf8 -t "us-ascii//ignore//translit" -c

i386: Add _dl_runtime_resolve_shstk [BZ #21598]
Add a SHSTK compatible symbol resolver to support Shadow Stack in Intel
Control-flow Enforcement Technology (CET) instructions:

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

Created attachment 10214
--> https://sourceware.org/bugzilla/attachment.cgi?id=10214&action=edit
C file that fails to compile with GCC
Hello, I reported a bug on the GCC bugtracker
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81156) and it might have
something to do with glibc, I am gonna copy & paste the original post here:
Hey, I ran into some problems compiling code that contained a specific formula.
I am using the type generic tgmath.h header because I am switching between
float and double for performance testing reasons.
If I include the tgmath.h header, the code doesn't compile, GCC ends up filling
up all my RAM and doesn't succeed to compile the file. It compiles using the
math.h header without a problem.
Here's the code in question (also in the attachment):
/* memory_leak.c */
#include <stdio.h>
#include <stdlib.h>
#include <tgmath.h>
#ifdef TEST_SP
typedef float test_float;
#else
typedef double test_float;
#endif
int main(int argc, char *argv[]) {
int b = -1;
test_float a, c, d, e, f, g, h, i;
a = c = d = e = f = g = h = i = 1;
a = 2*b/abs(b)*sqrt(pow(sqrt(pow(c, 2) - pow(d, 2)) -
e*f*cos(g)*cos(h)/abs(b)*(i - 1), 2) + pow(d/2, 2));
return 0;
}
/* END */
Compile with:
gcc -o memory_leak -DTEST_SP -std=c99 memory_leak.c -lm
It ends up eating all the memory there is.
Doesn't work on current GCC 7.1.1 on Arch nor on an RHEL6 distro with GCC
4.4.7.
Works with GCC 5.3 in Cygwin.
Clang and ICC compile without problems as well on Linux.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81156#c1 for Joseph's analysis
(combination explosion due to nested macros and repeated expansion).

commit 3ec7c02cc3e922b9364dc8cfd1d4546671b91003

x86-64: memcmp-avx2-movbe.S needs saturating subtraction [BZ #21662]
This code:
L(between_2_3):
/* Load as big endian with overlapping loads and bswap to avoid
branches. */
movzwl -2(%rdi, %rdx), %eax
movzwl -2(%rsi, %rdx), %ecx
shll $16, %eax
shll $16, %ecx
movzwl (%rdi), %edi
movzwl (%rsi), %esi
orl %edi, %eax
orl %esi, %ecx
bswap %eax
bswap %ecx
subl %ecx, %eax
ret
needs a saturating subtract because the full register is used.
With this commit, only the lower 24 bits of the register are used,
so a regular subtraction suffices.
The test case change adds coverage for these kinds of bugs.

Avoid .symver on common symbols [BZ #21666]
The .symver directive on common symbol just creates a new common symbol,
not an alias and the newer assembler with the bug fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21661
will issue an error. Before the fix, we got
$ readelf -sW libc.so | grep "loc[12s]"
5109: 00000000003a0608 8 OBJECT LOCAL DEFAULT 36 loc1
5188: 00000000003a0610 8 OBJECT LOCAL DEFAULT 36 loc2

in libc.so. The versioned loc1, loc2 and locs have the wrong addresses.
After the fix, we got

Bug ID: 21668
Summary: resolv: res_init cross-thread broadcast introduces
race conditions
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
The __res_initstamp mechanism can trigger a resolv.conf reload through
__res_maybe_init after an application (or getaddrinfo) has changed
_res.options. The reload will incorrect revert the change to _res.options.
I think the cross-thread broadcast is invalid and should go away in favor of
automated resolv.conf reloading (bug 984).

The .symver directive on common symbol just creates a new common symbol,

https://sourceware.org/bugzilla/show_bug.cgi?id=21661
will issue an error. Before the fix, we got

commit 2928381a81a334695f75c79e3b0c469c91741050
Author: H.J. Lu <hjl.tools@gmail.com>

Support build glibc with gold 1.14 or above [BZ #14995]
This patch changes configure.ac to allow gold 1.14 or above to be
used to configire glibc. Tested with
CC="gcc -fuse-ld=gold" CXX="g++ -fuse-ld=gold"
on Fedora 25 with gold 1.14 (20170623). Gold 1.14 was first released
in binutils 2.28.
For "make check", I got
Error in `/export/build/gnu/glibc-gold/build-x86_64-linux/elf/constload1':

--- Comment #1 from Sergei Trofimovich <slyfox at inbox dot ru> ---
Created attachment 10221
--> https://sourceware.org/bugzilla/attachment.cgi?id=10221&action=edit
0001-fix-pthread_create-crash-in-ia64.patch
The SIGSEGV is caused by the code responsible for stack cleanup
when thread exits. madvise(MADV_DONTNEED) is called on a part of stack
activelu being used at exit.
It happens because on ia64 stack grows from both sides of stack block:
- normal "sp" stack (stack for local variables) grows down
- register stack "bsp" grows up from the opposite end of stack block
madvise(MADV_DONTNEED) effectively does memset(0) register stack
which causes SIGSEGV at address 0x8 afterwards when a pointer frop
stack is being dereferenced.

Bug ID: 21673
Summary: a regexec call with REG_STARTEND finds a bogus match
for \>
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: regex
Assignee: unassigned at sourceware dot org
Reporter: bensberg at telfort dot nl
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 10222
--> https://sourceware.org/bugzilla/attachment.cgi?id=10222&action=edit
tiny program that searches for \> starting from two different positions
When calling regexec with the REG_STARTEND flag and providing
an end-of-range value (in .rm_eo) that points to somewhere in
the middle of a word, regexec will nevertheless find a match
for \> at that offset. The corresponding case for \<, with a
start-of-range value (in .rm_so) that points to the middle of
a word, will /not/ find a match for \< there. The latter is
what I expected, the former was a surprise.
To reproduce:
Compile the attached until.c and run it.
The actual output is:
Found tail at 6: '. '
Found tail at 4: 'rd. '
Expected result:
The second line of output shouldn't have been there, because
the word does not end after "wo".
First seen on Ubuntu Lucid (10.04). Still present on Ubuntu
Zesty (17.04, glibc 2.24).

Support building glibc with gold 1.14 or above [BZ #14995]
This patch changes configure.ac to allow gold 1.14 or above to be used
to configire glibc so that gold glibc bugs can be fixed. Tested with
CC="gcc -fuse-ld=gold" CXX="g++ -fuse-ld=gold"
on Fedora 25 with gold 1.14 (20170623). Gold 1.14 was first released
in binutils 2.28.
For "make check", I got

commit 3f823e87ccbf3723eb4eeb63b0619f1a0ceb174e
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Jun 22 08:49:34 2017 -0300
Call exit directly in clone (BZ #21512)
On aarch64, alpha, arm, hppa, mips, nios2, powerpc, sh, sparc, tile,
and x86_64 the clone syscall jumps to _exit after the child execution
and the function ends the process execution by calling exit_group.
This behavior have a small issue where threads created with
CLONE_THREAD using clone syscall directly will eventually exit the
whole group altogether instead of just the thread created. Also,
s390, microblaze, ia64, i386, and m68k differs by calling exit
syscall directly.
This patch changes all architectures to call the exit syscall
directly, as for s390, microblaze, ia64, i386, and m68k. This do not
have change glibc internal behavior in any sort, since the only
usage of clone implementation in posix_spawn calls _exit directly
in the created child (fork uses a direct call to clone).
Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
powerpc-linux-gnu, powerpc64le-linux-gnu, sparc64-linux-gnu,
and sparcv9-linux-gnu.

commit 251287734e89a52da3db682a8241eb6bccc050c9
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Jun 26 22:03:58 2017 +0000
Rename struct ucontext tag (bug 21457).
The ucontext_t type has a tag struct ucontext. As with previous such
issues for siginfo_t and stack_t, this tag is not permitted by POSIX
(is not in a reserved namespace), and so namespace conformance means
breaking C++ name mangling for this type.
In this case, the type does need to have some tag rather than just a
typedef name, because it includes a pointer to itself. This patch
uses struct ucontext_t as the new tag, so the type is mangled as
ucontext_t (the POSIX *_t reservation applies in all namespaces, not
just the namespace of ordinary identifiers). Another reserved name
such as struct __ucontext could of course be used.
Because of other namespace issues, this patch does not by itself fix
bug 21457 or allow any XFAILs to be removed.
Tested for x86_64, and with build-many-glibcs.py.

Created attachment 10223
--> https://sourceware.org/bugzilla/attachment.cgi?id=10223&action=edit
Proposed patch for avoiding the compiler warning
I am adding a possible patch, which makes the 2 variables volatile, so the
compiler no longer warns about them.
The patch also includes a test case, which is checking for whether the warning
is emitted or not.
I tested with glibc 2.25, both unpatched and patched, and it behaves as
expected.
The unpatched toolkit will get an error in the test case when the
pthread_cleanup_push() macro is used while the patched toolkit will not.
The test itself does nothing.

Patches go to libc-alpha (make sure to include the analysis of the paths
through the code that indicate there is a real problem here).

--- Comment #22 from Mike FABIAN <maiku.fabian at gmail dot com> ---
I (In reply to Zack Weinberg from comment #19)

Yes, I think the same as Zack, we should not let this stuff hanging for
a long time, we should trust CLDR. There are some bugs in CLDR, but
we should report them as bugs against CLDR if we find any. And then let
the fix come back to glibc by syncing.
I checked Rafal’s patches in this bug as carefully as I could, I could
not find any problems. Therefore, I have committed them.

--- Comment #21 from Stephen Dolan <stephen.dolan at cl dot cam.ac.uk> ---
> However, the test is not guaranteed to terminate because C would
> consume the signal that both B and C are allowed to consume.
You're correct. The test has multiple valid behaviours, including one
where it hangs after printing "A woke". However, none of these valid
behaviours fail to print "A woke", which is what I observed.
> Furthermore, I know what you're trying to do with the sleep in the
> signal handler, but is sleep() actually allowed in a handler?
POSIX specifies that sleep is async-signal-safe. (Oddly, it makes no
such guarantee for usleep or nanosleep).
> This execution should not happen. B and C consume the two signals
> (C doesn't time out), but A should be woken in any case.
I'm glad we agree! I was worried (by some of the comments in this
thread, and by the fact that this bug is marked INVALID) that you
thought this behaviour was correct.
> Please do test it with a current version of glibc.
I've now tested it with glibc 2.24 and glibc 2.25. 2.24 has the bug,
but 2.25 seems to work.

Created attachment 10225
--> https://sourceware.org/bugzilla/attachment.cgi?id=10225&action=edit
Provide backward compatibility for nl_langinfo family (version 8)
Here is the new set of patches. The changes are mostly the rebase to the
current master and applying the latest changes in the source code repository
(like: Use locale_t, not __locale_t
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=af85385). Some patches
are skipped because there are no relevant changes:
--------
SKIPPED PATCHES:
0001 Implement alternative month names - same as in comment 83
--------
This is the new patch 0002. Difference between the patch from comment 84 and
this one: rebased against the current master, reflects the change to use
locale_t rather than __locale_t.

https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=d57cb31910ca5c200e4172276749a7f8bd17ae3c
commit d57cb31910ca5c200e4172276749a7f8bd17ae3c
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Jun 28 10:33:23 2017 +0000
Miscellaneous sys/ucontext.h namespace fixes (bug 21457).
This patch fixes various miscellaneous namespace issues in
sys/ucontext.h headers.
Some struct tags are removed where the structs also have *_t typedef
names, while other struct tags without such names are renamed to start
__; the changes are noted in NEWS as they can affect C++ name mangling
(although there seems to be little if any external use of these types,
at least based on checking codesearch.debian.net). For powerpc,
pointers to struct pt_regs (not defined in this header) are changed to
point to struct __ctx(pt_regs), so in the __USE_MISC case those struct
fields continue to point to the existing struct pt_regs type for
maximum compatibility, while when that's a namespace issue they point
to a struct __pt_regs type which is always an incomplete struct.
Tested for affected architectures with build-many-glibcs.py.
[BZ #21457]
* sysdeps/unix/sysv/linux/m68k/sys/ucontext.h (fpregset_t): Remove
struct tag.
* sysdeps/unix/sysv/linux/mips/sys/ucontext.h (fpregset_t):
Likewise.
* sysdeps/unix/sysv/linux/nios2/sys/ucontext.h (mcontext_t):
Likewise.
* sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h (pt_regs):
Declare struct type with __ctx.
[__WORDSIZE != 32] (mcontext_t): Use __ctx with pt_regs struct
tag.
(ucontext_t) [__WORDSIZE == 32]: Use __ctx with pt_regs struct tag
and regs field name.

Support building glibc with gold 1.14 or above [BZ #14995]
This patch changes configure.ac to allow gold 1.14 or above to be used
to configire glibc so that gold glibc bugs can be fixed. Tested with
CC="gcc -fuse-ld=gold" CXX="g++ -fuse-ld=gold"
on Fedora 25 with gold 1.14 (20170623). Gold 1.14 was first released
in binutils 2.28.
On x86-64, for "make check", I got
Error in `/export/build/gnu/glibc-gold/build-x86_64-linux/elf/constload1':
double free or corruption (fasttop): 0x00000000008755f0 ***

Summary: tgmath.h handling of complex integers

Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
Target Milestone: ---
The tgmath.h macros return a real type not a complex type when an argument is
of complex integer type (a GNU extension) and there are no arguments of complex
floating type. (__tgmath_real_type_sub produces double in such a case when it
seems clear it ought to produce _Complex double for a complex integer type.)

Severity: normal

Assignee: unassigned at sourceware dot org

Target Milestone: ---
The tgmath.h macros produce errors for bit-field arguments, because they apply
typeof to the arguments. Applying unary + to the arguments inside typeof
should avoid that problem.

This works on architectures that don't use COPY relocations.

Bug ID: 21686
Summary: tgmath.h handling of __int128
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
Target Milestone: ---
When a tgmath.h macro is passed a double argument and an argument of type
__int128, it generates a call to a long double function (although the result
still gets converted to type double). __int128 is similar enough to integer
types that it should be handled consistently like them, so always like double
for these macros rather than sometimes like double and sometimes like long
double.

commit 51737193a9810ceb1c516a2a71444fa70bcf8500
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Jun 28 16:01:20 2017 +0000
Remove NO_LONG_DOUBLE conditionals in libm tests (bug 21607).
As noted in bug 21607, NO_LONG_DOUBLE conditionals in libm tests are
no longer effective. For most this is harmless - they were only
present because of long double functions not being declared with _LIBC
defined, and _LIBC is no longer defined for building most tests. For
the few where this is actually relevant to the test, testing
LDBL_MANT_DIG > DBL_MANT_DIG is more appropriate as that limits the
test to public APIs. This patch fixes the tests accordingly.
Tested for x86_64 and arm.
[BZ #21607]
* math/basic-test.c [!NO_LONG_DOUBLE]: Change conditionals to
[LDBL_MANT_DIG > DBL_MANT_DIG].
* math/bug-nextafter.c [!NO_LONG_DOUBLE]: Remove conditionals.

Fixed for 2.26. The canonicalize test failures you mention are something else;
if it's arithmetic on sNaNs not preserving payloads, define
SNAN_TESTS_PRESERVE_PAYLOAD to 0 in math-tests.h.

Fix tgmath.h totalorder, totalordermag return type (bug 21687).
The tgmath.h totalorder and totalordermag macros wrongly return a
floating-point type. They should return int, like the underlying
functions. This patch fixes them accordingly, updating tests
including enabling tests of those functions from gen-tgmath-tests.py.
Tested for x86_64.
[BZ #21687]
* math/tgmath.h (__TGMATH_BINARY_REAL_RET_ONLY): New macro.
(totalorder): Use it.
(totalordermag): Likewise.
* math/gen-tgmath-tests.py (Tests.add_all_tests): Enable tests of
totalorder and totalordermag.
* math/test-tgmath.c (F(compile_test)): Do not call totalorder or
totalordermag in arguments of calls to those functions.
(NCALLS): Change to 134.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.

is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

--- Comment #8 from Peter Maydell <peter.maydell at linaro dot org> ---
The changes in this bug appear to break building QEMU with this version of
glibc (we use "struct ucontext" rather than "ucontext_t"). Can this be
reverted, please? I think breaking real world code for the purposes of a
theoretical namespace cleanup is not an ideal tradeoff.

The GNU C Library does not provide backwards compatibility at the API level.
When recompiling your code you may need to fix things as existing APIs are
deprecated.
Namespace issues are real and impact applications and the names they can use
for their own variables, such work is just as importance as performance work in
the longer term.
If you need to build a new QEMU, you need to fix the new QEMU to build with the
new glibc. This is a normal part of building with a new toolchain.
There is a C++ ABI change with the change of the structure name, but analysis
of distribution binaries shows this should not be an issue, though we would
appreciate any feedback on that aspect of the change.

--- Comment #11 from Peter Maydell <peter.maydell at linaro dot org> ---
I would object less if this had been deprecated, ie if the new glibc produced a
warning on compilation and some future release would then remove it. It has not
been deprecated, it has been simply removed.

Correct, in this case we removed the definition completely after analyzing the
code that was using such a definition. A deprecation phase was not considered
because the impact of the change was small relative to the number of
potentially impacted packages. A good comparison is the _DEFAULT_SOURCE changes
in 2.20 (https://sourceware.org/glibc/wiki/Release/2.20#Packaging_Changes)
where we had a multi-stage deprecation for something we knew would impact a lot
of packages.
While we would like to have staged deprecation for every change we make, it's
not practical, and is weighed against the cost and number of impacted packages,
and the complexity of the change. Here it's a simple name change to fix
longterm namespace issues.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

--- Comment #13 from Peter Maydell <peter.maydell at linaro dot org> ---
I think that's unfortunate, because given how widely and pervasively used glibc
is, pretty much any non-API-back-compatible change you make is likely to break
some of your users, and so it would be very helpful if all such changes were
preceded by a deprecation phase.

x86: Add <sys/cet.h> to support Intel CET
To support Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
include sysdeps/unix/sysv/linux/x86/sys/cet.h for assembly codes so that
ELF program property can be added to relocatable objects generated from
assembly codes if defines__IBT__ or __SHSTK__ is defined. If compiler
defines__IBT__, the IBT bit is turned on in x86 feature. If compiler
defines __SHSTK__, the SHSTK bit is turned on in x86 feature.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

--- Comment #14 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
I'm not aware of any way to mark a struct tag as deprecated without
deprecating use of that type through the ucontext_t typedef name.
In this case, ucontext_t should work with all glibc versions and non-glibc
libraries, so changing struct ucontext to ucontext_t unconditionally
should be appropriate for all users.
Even adding a new function can break things for applications (using
_DEFAULT_SOURCE / _GNU_SOURCE) that use that name for something else; I
don't think we can reasonably have a deprecation process before adding new
functions. (In some cases we act specially to improve compatibility, e.g.
how iszero is defined as a template instead of a macro for C++ because of
various code broken by the macro.)
Dealing with the namespace issues here, and thus in signal.h and
sys/wait.h, allows eliminating various conform/ XFAILs and makes it a lot
easier to see what other header namespace issues there are in those
headers, or issues with headers not defining symbols they should define -
and so facilitates finding and fixing architecture-specific header bugs
and avoiding such issues creeping in accidentally in future. (Note that
the XFAIL removal still depends on my pending-review patches to stop
mcontext_t being struct sigcontext on some architectures and to fix SPARC
header namespace bugs.)

--- Comment #15 from Peter Maydell <peter.maydell at linaro dot org> ---
The issue is with other projects whose release cycles aren't necessarily
aligned with glibc's. We can certainly update QEMU now, but that means that
until we do our next QEMU release, people running new glibc will have no
released version of QEMU that will build on their system. If glibc has a
deprecation period before actually removing things, then we get advance notice
that we need to make a fix, and so we're likely to be able to release a fixed
QEMU before the glibc is released which actually removes the feature we were
using.
If you need new compiler features to be able to implement this for some kinds
of deprecation you can talk to the gcc folk :-)
Incidentally, I notice that the getcontext(3) manpage for Linux describes
"struct ucontext" -- does that need updating?

instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines__IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<sys/cet.h> is added so that it can be included by assembly codes to
add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

SPARC sys/ucontext.h namespace fixes (bug 21457).
This patch fixes various miscellaneous namespace issues in the SPARC
sys/ucontext.h header. These are similar to changes made previous to
other sys/ucontext.h headers, where the SPARC header was excluded from
those previous patches because of its complexity.
Tested for SPARC with build-many-glibcs.py.

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines__IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<sys/cet.h> is added so that it can be included by assembly codes to
add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

I pushed these fixes, with the following minor changes:
The change "az_AZ: changing Azərbaycanca to azərbaycan dili"
disagrees with CLDR, but I think it is correct, I should
probably report a bug against CLDR.
id_ID: changing Bahasa Ind/onesia to Indonesia <- this seems wrong, I
think it should be "Bahasa Indonesia",
Therefore, I reported:
http://unicode.org/cldr/trac/ticket/10405
uz_UZ@cyrillic: changing Ўзбекча to Ўзбек <- most recent CLDR trunk
has ўзбекча, so probably this should stay as it is.
So for Korean, lang_name has also been changed from "í•œêµë§" to "í•œêµì–´"
as requested.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch increases the malloc alignment to 16 for i386.
[BZ #21120]
* sysdeps/generic/malloc-alignment.h: New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

--- Comment #28 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
Since the removal of bits/string.h, _HAVE_STRING_ARCH_* are no longer used.
The (useless) defines of such macros should be removed from
sysdeps/x86_64/multiarch/*.c, and this bug closed.

Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from
"#include_next" (instead of stdlib/stdlib.h in the glibc source
directory), and this turns up as a make dependency. Also make a copy
of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h.
[BZ #21573]
* Makerules [$(c++-bits-std_abs-h) != ""] (before-compile): Add
$(common-objpfx)bits/std_abs.h.
[$(c++-bits-std_abs-h) != ""] ($(common-objpfx)bits/std_abs.h):
New target.
* config.make.in (c++-bits-std_abs-h): New.
* configure.ac (find_cxx_header): Use "\,$1," with sed.
(CXX_BITS_STD_ABS_H): New.

Avoid .symver on common symbols [BZ #21666]
The .symver directive on common symbol just creates a new common symbol,
not an alias and the newer assembler with the bug fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21661
will issue an error. Before the fix, we got

Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from
"#include_next" (instead of stdlib/stdlib.h in the glibc source
directory), and this turns up as a make dependency. Also make a copy
of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h.
[BZ #21573]
* Makerules [$(c++-bits-std_abs-h) != ""] (before-compile): Add
$(common-objpfx)bits/std_abs.h.
[$(c++-bits-std_abs-h) != ""] ($(common-objpfx)bits/std_abs.h):
New target.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch increases the malloc alignment to 16 for i386.

* sysdeps/generic/malloc-alignment.h: New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Get rid of duplicate const declaration specifier warning in
tst-resolv-qtypes.c.
Compiling resolv/tst-resolv-qtypes.c with GCC 7 results in:
tst-resolv-qtypes.c:53:14: error: duplicate ‘const’ declaration specifier
[-Werror=duplicate-decl-specifier]
static const const char *domain = "www.example.com";
This patch removes the duplicate const and makes domain a const pointer
to const char literal.
ChangeLog:
* resolv/tst-resolv-qtypes.c (domain):
Change type to const pointer to const char.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=
around tests of strncat with large sizes.

Fix testsuite build for GCC 7 -Wformat-truncation.
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.
* stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore
-Wformat-truncation instead of -Wformat-length.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):
Compare name == NULL, not name != NULL.

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.
* sunrpc/Makefile [$(run-built-tests) = yes] (rpcgen-tests): New

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]

Get rid of duplicate const declaration specifier warning in
tst-resolv-qtypes.c.
Compiling resolv/tst-resolv-qtypes.c with GCC 7 results in:
tst-resolv-qtypes.c:53:14: error: duplicate ‘const’ declaration specifier
[-Werror=duplicate-decl-specifier]
static const const char *domain = "www.example.com";
This patch removes the duplicate const and makes domain a const pointer
to const char literal.
ChangeLog:
* resolv/tst-resolv-qtypes.c (domain):
Change type to const pointer to const char.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=
around tests of strncat with large sizes.

Fix malloc/ tests for GCC 7 -Walloc-size-larger-than=.
GCC 7 has a -Walloc-size-larger-than= warning for allocations of half

arranges for this warning to be ignored around the problematic
function calls.

Fix testsuite build for GCC 7 -Wformat-truncation.
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.
* stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore
-Wformat-truncation instead of -Wformat-length.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):
Compare name == NULL, not name != NULL.

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.
* sunrpc/Makefile [$(run-built-tests) = yes] (rpcgen-tests): New

<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch increases the malloc alignment to 16 for i386.

Get rid of duplicate const declaration specifier warning in
tst-resolv-qtypes.c.
Compiling resolv/tst-resolv-qtypes.c with GCC 7 results in:
tst-resolv-qtypes.c:53:14: error: duplicate ‘const’ declaration specifier
[-Werror=duplicate-decl-specifier]
static const const char *domain = "www.example.com";
This patch removes the duplicate const and makes domain a const pointer
to const char literal.
ChangeLog:
* resolv/tst-resolv-qtypes.c (domain):
Change type to const pointer to const char.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=
around tests of strncat with large sizes.

Fix testsuite build for GCC 7 -Wformat-truncation.
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.
* stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore
-Wformat-truncation instead of -Wformat-length.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):
Compare name == NULL, not name != NULL.

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.
* sunrpc/Makefile [$(run-built-tests) = yes] (rpcgen-tests): New

Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch increases the malloc alignment to 16 for i386.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch increases the malloc alignment to 16 for i386.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.

* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch increases the malloc alignment to 16 for i386.
[BZ #21120]
* sysdeps/generic/malloc-alignment.h: New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=
around tests of strncat with large sizes.

Fix testsuite build for GCC 7 -Wformat-truncation.
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.

Avoid running $(CXX) during build to obtain header file paths
This reduces the build time somewhat and is particularly noticeable
during rebuilds with few code changes.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch increases the malloc alignment to 16 for i386.
[BZ #21120]
* sysdeps/generic/malloc-alignment.h: New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Avoid .symver on common symbols [BZ #21666]
The .symver directive on common symbol just creates a new common symbol,
not an alias and the newer assembler with the bug fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21661
will issue an error. Before the fix, we got

in libc.so. The versioned loc1, loc2 and locs have the wrong addresses.
After the fix, we got

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h>
and increases the malloc alignment to 16 for i386.
[BZ #21120]
* malloc/malloc-internal.h (MALLOC_ALIGNMENT): Moved to ...
* sysdeps/generic/malloc-alignment.h: Here. New file.
* sysdeps/i386/malloc-alignment.h: Likewise.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h>
and increases the malloc alignment to 16 for i386.
[BZ #21120]
* malloc/malloc.c (MALLOC_ALIGNMENT): Moved to ...
* sysdeps/generic/malloc-alignment.h: Here. New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=
around tests of strncat with large sizes.

Fix malloc/ tests for GCC 7 -Walloc-size-larger-than=.
GCC 7 has a -Walloc-size-larger-than= warning for allocations of half

arranges for this warning to be ignored around the problematic
function calls.

Fix testsuite build for GCC 7 -Wformat-truncation.
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.
* stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore
-Wformat-truncation instead of -Wformat-length.
* time/tst-strptime2.c (mkbuf) [__GNUC_PREREQ (7, 0)]: Likewise.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):
Compare name == NULL, not name != NULL.

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.
* sunrpc/Makefile [$(run-built-tests) = yes] (rpcgen-tests): New
variable.
[$(run-built-tests) = yes] (tests-special): Add $(rpcgen-tests).
[$(run-built-tests) = yes] ($(rpcgen-tests)): New rule.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h>
and increases the malloc alignment to 16 for i386.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=
around tests of strncat with large sizes.

Fix testsuite build for GCC 7 -Wformat-truncation.
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.
* stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore
-Wformat-truncation instead of -Wformat-length.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):
Compare name == NULL, not name != NULL.

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.
* sunrpc/Makefile [$(run-built-tests) = yes] (rpcgen-tests): New
variable.
[$(run-built-tests) = yes] (tests-special): Add $(rpcgen-tests).

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h>
and increases the malloc alignment to 16 for i386.
[BZ #21120]
* malloc/malloc.c (MALLOC_ALIGNMENT): Moved to ...
* sysdeps/generic/malloc-alignment.h: Here. New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.
* sunrpc/Makefile [$(run-built-tests) = yes] (rpcgen-tests): New

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h>
and increases the malloc alignment to 16 for i386.
[BZ #21120]
* malloc/malloc.c (MALLOC_ALIGNMENT): Moved to ...
* sysdeps/generic/malloc-alignment.h: Here. New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)

rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h>
and increases the malloc alignment to 16 for i386.
[BZ #21120]
* malloc/malloc.c (MALLOC_ALIGNMENT): Moved to ...
* sysdeps/generic/malloc-alignment.h: Here. New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.

* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size

Avoid .symver on common symbols [BZ #21666]
The .symver directive on common symbol just creates a new common symbol,
not an alias and the newer assembler with the bug fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21661
will issue an error. Before the fix, we got

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h>
and increases the malloc alignment to 16 for i386.
[BZ #21120]
* malloc/malloc.c (MALLOC_ALIGNMENT): Moved to ...
* sysdeps/generic/malloc-alignment.h: Here. New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Get rid of duplicate const declaration specifier warning in
tst-resolv-qtypes.c.
Compiling resolv/tst-resolv-qtypes.c with GCC 7 results in:
tst-resolv-qtypes.c:53:14: error: duplicate ‘const’ declaration specifier
[-Werror=duplicate-decl-specifier]
static const const char *domain = "www.example.com";
This patch removes the duplicate const and makes domain a const pointer
to const char literal.
ChangeLog:
* resolv/tst-resolv-qtypes.c (domain):
Change type to const pointer to const char.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=
around tests of strncat with large sizes.

Fix testsuite build for GCC 7 -Wformat-truncation.
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.
* stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore
-Wformat-truncation instead of -Wformat-length.
* time/tst-strptime2.c (mkbuf) [__GNUC_PREREQ (7, 0)]: Likewise.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):
Compare name == NULL, not name != NULL.

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the
destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a
destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.
* sunrpc/Makefile [$(run-built-tests) = yes] (rpcgen-tests): New
variable.
[$(run-built-tests) = yes] (tests-special): Add $(rpcgen-tests).
[$(run-built-tests) = yes] ($(rpcgen-tests)): New rule.

Bug ID: 21696
Summary: Incorrect assumption of of __cpu_mask in
posix/sched_cpucount.c
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org

CC: drepper.fsp at gmail dot com
Target Milestone: ---
posix/sched_cpucount.c has
int
__sched_cpucount (size_t setsize, const cpu_set_t *setp)
{
int s = 0;
const __cpu_mask *p = setp->__bits;
const __cpu_mask *end = &setp->__bits[setsize / sizeof (__cpu_mask)];
while (p < end)
{
__cpu_mask l = *p++;
#ifdef POPCNT
s += POPCNT (l);
#else
if (l == 0)
continue;
# if LONG_BIT > 32
l = (l & 0x5555555555555555ul) + ((l >> 1) & 0x5555555555555555ul);
l = (l & 0x3333333333333333ul) + ((l >> 2) & 0x3333333333333333ul);
l = (l & 0x0f0f0f0f0f0f0f0ful) + ((l >> 4) & 0x0f0f0f0f0f0f0f0ful);
l = (l & 0x00ff00ff00ff00fful) + ((l >> 8) & 0x00ff00ff00ff00fful);
l = (l & 0x0000ffff0000fffful) + ((l >> 16) & 0x0000ffff0000fffful);
l = (l & 0x00000000fffffffful) + ((l >> 32) & 0x00000000fffffffful);
# else
l = (l & 0x55555555ul) + ((l >> 1) & 0x55555555ul);
l = (l & 0x33333333ul) + ((l >> 2) & 0x33333333ul);
l = (l & 0x0f0f0f0ful) + ((l >> 4) & 0x0f0f0f0ful);
l = (l & 0x00ff00fful) + ((l >> 8) & 0x00ff00fful);
l = (l & 0x0000fffful) + ((l >> 16) & 0x0000fffful);
# endif
s += l;
#endif
}
return s;
}
This implementation assumes size of __cpu_mask == size of LONG. On x32,
(gdb) whatis __cpu_mask
type = __u_quad_t
(gdb) p sizeof (__u_quad_t)
$11 = 8
and the above assumption is incorrect.

Date: Sat Jul 1 07:29:19 2017 -0700
Use __builtin_popcount in __sched_cpucount [BZ #21696]
posix/sched_cpucount.c assumes that size of __cpu_mask == size of long,
which is incorrect for x32. This patch uses __builtin_popcount, which
is availabe in GCC 4.9, in posix/sched_cpucount.c.
Tested on i686, x86-64 and x32 with multi-arch disabled.
[BZ #21696]
* posix/sched_cpucount.c: Don't include <limits.h>.
(__sched_cpucount): Use __builtin_popcount.

RES_USE_INET6 and the “inet6†option are not related to this. Instead, they
change the type of addresses produced by gethostname. Many applications are
incompatible with this. See bug 19582.

Bug ID: 21701
Summary: resolv: Reloading /etc/resolv.conf does not clear
flags
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
If /etc/resolv.conf has a setting
options rotate edns0
and a process loads the file, but then the file is changed to
options rotate
and loaded again, the RES_USE_EDNS0 flag persists. This happens even with
explicit calls to res_init.
In short, res_init never clears flags. This is slightly different from bug
14799. It is reasonable to expect that with resolv.conf reloading (by whatever
means), the changes actually take effect.

commit 352f4ff9a268b81ef5d4b2413f582565806e4790
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Jun 30 21:10:23 2017 +0200
resolv: Introduce struct resolv_context [BZ #21668]
struct resolv_context objects provide a temporary resolver context
which does not change during a name lookup operation. Only when the
outmost context is created, the stub resolver configuration is
verified to be current (at present, only against previous res_init
calls). Subsequent attempts to obtain the context will reuse the
result of the initial verification operation.
struct resolv_context can also be extended in the future to store
data which needs to be deallocated during thread cancellation.

resolv: Automatically reload a changed /etc/resolv.conf file [BZ #984]
This commit enhances the stub resolver to reload the configuration
in the per-thread _res object if the /etc/resolv.conf file has
changed. The resolver checks whether the application has modified
_res and will not overwrite the _res object in that case.
The struct resolv_context mechanism is used to check the
configuration file only once per name lookup.

--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
The automated resolv.conf reloading added in commit
aef16cc8a4c670036d45590877d411a97f01e0cd for glibc 2.26 mitigates this somewhat
because automated reloads do not have this problem. As a result, applications
which never modify _res and never call res_init do not have this issue.

Status: NEW
Severity: normal

x86-64: Align the stack in __tls_get_addr [BZ #21609]
This change forces realignment of the stack pointer in __tls_get_addr, so
that binaries compiled by GCCs older than GCC 4.9:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
continue to work even if vector instructions are used in glibc which
require the ABI stack realignment.
__tls_get_addr_slow is added to handle the slow paths in the default
implementation of__tls_get_addr in elf/dl-tls.c. The new __tls_get_addr
calls __tls_get_addr_slow after realigning the stack.
2017-07-03 Florian Weimer <fweimer@redhat.com>
H.J. Lu <hongjiu.lu@intel.com>
[BZ #21609]
* sysdeps/x86_64/Makefile (sysdep-dl-routines): Add tls_get_addr.
(gen-as-const-headers): Add rtld-offsets.sym.
* sysdeps/x86_64/dl-tls.c: New file.
* sysdeps/x86_64/rtld-offsets.sym: Likwise.

* sysdeps/x86_64/dl-tls.h: Add multiple inclusion guards.
* sysdeps/x86_64/tlsdesc.sym (TI_MODULE_OFFSET): New.
(TI_OFFSET_OFFSET): Likwise.

x86-64: Align the stack in __tls_get_addr [BZ #21609]
This change forces realignment of the stack pointer in __tls_get_addr, so
that old GCC-compiled binaries continue to work even if vector instructions
are used in glibc which require the ABI stack realignment.
The implementation of __tls_get_addr calls the default implementation
(from elf/dl-tls.c, now calls __tls_get_addr_default) after realigning
the stack. Internal calls go directly to __tls_get_addr_default because
they do not need stack realignment.

I was testing f0107724c92eef (and you very well know that one cannot possibly
test commits from the future, that you have just committed minutes ago.)
Anyway, the issue got fixed by 4446a885f3aeb.

x86-64: Align the stack in __tls_get_addr [BZ #21609]
This change forces realignment of the stack pointer in __tls_get_addr, so
that binaries compiled by GCCs older than GCC 4.9:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
continue to work even if vector instructions are used in glibc which
require the ABI stack realignment.
__tls_get_addr_slow is added to handle the slow paths in the default
implementation of__tls_get_addr in elf/dl-tls.c. The new __tls_get_addr
calls __tls_get_addr_slow after realigning the stack. Internal calls
within ld.so go directly to the default implementation of __tls_get_addr
because they do not need stack realignment.
2017-07-04 Florian Weimer <fweimer@redhat.com>
H.J. Lu <hongjiu.lu@intel.com>
[BZ #21609]
* sysdeps/x86_64/Makefile (sysdep-dl-routines): Add tls_get_addr.
(gen-as-const-headers): Add rtld-offsets.sym.
* sysdeps/x86_64/dl-tls.c: New file.

x86-64: Export ___tls_get_addr
On x86-64, __tls_get_addr is changed to realign stack to support GCC
older than GCC 4.9.4:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
This patch exports ___tls_get_addr as the alternative x86-64 runtime
interface to TLS with aligned stack.
This requires linker support for TLS optimization with ___tls_get_addr.
GCC 4.9.4 and newer can generate call to ___tls_get_addr, instead of
__tls_get_addr. We can use the weakref assembly directive to redirect
__tls_get_addr to ___tls_get_addr if linker supports ___tls_get_addr and
GCC doesn't.
* sysdeps/unix/sysv/linux/x86_64/64/ld.abilist: Add GLIBC_2.26
and ___tls_get_addr.
* sysdeps/unix/sysv/linux/x86_64/x32/ld.abilist: Likewise.
* sysdeps/x86_64/Versions: Export ___tls_get_addr in GLIBC_2.26.

ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines__IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<sys/cet.h> is added so that it can be included by assembly codes to
add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

x86-64: Redirect __tls_get_addr to ___tls_get_addr
On x86-64, __tls_get_addr realigns stack to support GCC older than GCC
4.9.4:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
___tls_get_addr is the alternative x86-64 runtime interface to TLS with
aligned stack. If linker treats ___tls_get_addr just like __tls_get_addr
and the weakref assembly directive is extended to redirect __tls_get_addr
to ___tls_get_addr, we can replace reference to __tls_get_addr with
___tls_get_addr if GCC aligns stack for __tls_get_addr, but doesn't
support ___tls_get_addr.
* sysdeps/x86_64/Makefile (+cflags): New. Add
-include $(..)sysdeps/x86_64/tls_get_addr.h if __tls_get_addr
can be redireted to ___tls_get_addr.
* sysdeps/x86_64/configure.ac: Check if GCC supports
___tls_get_addr. If not, check if __tls_get_addr to
___tls_get_addr redirection works.
* sysdeps/x86_64/configure: Regenerated.
* sysdeps/x86_64/tls_get_addr.h: New file.

commit 639d0d5203cc112dc775d030ad794217a8d34025
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Tue Jul 4 09:24:09 2017 -0700
x86-64: Export ___tls_get_addr
On x86-64, __tls_get_addr is changed to realign stack to support GCC
older than GCC 4.9.4:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
This patch exports ___tls_get_addr as the alternative x86-64 runtime
interface to TLS with aligned stack.
This requires linker support for TLS optimization with ___tls_get_addr.
GCC 4.9.4 and newer can generate call to ___tls_get_addr, instead of
__tls_get_addr. We can use the weakref assembly directive to redirect
__tls_get_addr to ___tls_get_addr if linker supports ___tls_get_addr and
GCC doesn't.
* sysdeps/unix/sysv/linux/x86_64/64/ld.abilist: Add GLIBC_2.26
and ___tls_get_addr.
* sysdeps/unix/sysv/linux/x86_64/x32/ld.abilist: Likewise.
* sysdeps/x86_64/Versions: Export ___tls_get_addr in GLIBC_2.26.

commit 08659292af38dffbbec9f07103708f8b5ea48e4c
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Mon Jul 3 13:16:57 2017 -0700
x86-64: Align the stack in __tls_get_addr [BZ #21609]
This change forces realignment of the stack pointer in __tls_get_addr, so
that binaries compiled by GCCs older than GCC 4.9:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
continue to work even if vector instructions are used in glibc which
require the ABI stack realignment.
__tls_get_addr_slow is added to handle the slow paths in the default
implementation of__tls_get_addr in elf/dl-tls.c. The new __tls_get_addr
calls __tls_get_addr_slow after realigning the stack. Internal calls
within ld.so go directly to the default implementation of __tls_get_addr
because they do not need stack realignment.
2017-07-04 Florian Weimer <fweimer@redhat.com>
H.J. Lu <hongjiu.lu@intel.com>
[BZ #21609]
* sysdeps/x86_64/Makefile (sysdep-dl-routines): Add tls_get_addr.
(gen-as-const-headers): Add rtld-offsets.sym.
* sysdeps/x86_64/dl-tls.c: New file.
* sysdeps/x86_64/rtld-offsets.sym: Likwise.
* sysdeps/x86_64/tls_get_addr.S: Likewise.
* sysdeps/x86_64/dl-tls.h: Add multiple inclusion guards.
* sysdeps/x86_64/tlsdesc.sym (TI_MODULE_OFFSET): New.
(TI_OFFSET_OFFSET): Likwise.

Bug ID: 21713
Summary: cacheinfo.c handle_intel errors on 486 processors
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: tedheadster at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
This bug presumes we support ancient 32 bit i486 processors.
In sysdeps/x86_64/cacheinfo.c (called from 32bit i386 systems, oddly) it calls
handle_intel(). It immediately does an "assert(maxidx >= 2)". This fails on
early i486 processors, and I believe it even fails on Pentium 1 cpus.
Unfortunately, my Gentoo /sbin/init uses /lib/libc.so.6, so the system panics
when init gets a general protection fault and dies on the assert().
I was able to get the system to boot with the following patch, but it is
probably not the right solution:
--- glibc-2.23/sysdeps/x86_64/cacheinfo.c
+++ tmp/cacheinfo.c
@@ -259,7 +259,8 @@
static long int __attribute__ ((noinline))
handle_intel (int name, unsigned int maxidx)
{
- assert (maxidx >= 2);
+ if (maxidx < 2)
+ return 0;
/* OK, we can use the CPUID instruction to get all info about the
caches. */

Fiji Hindi Locale not committed yet, only the Tok Pisin locale is committed,
so only part of this bug is fixed so far.

--- Comment #3 from Florian Weimer <fweimer at redhat dot com> ---
This causes failures in the test suite even without --enable-bind-now:
FAIL: dlfcn/tststatic
FAIL: dlfcn/tststatic2
FAIL: dlfcn/tststatic3
FAIL: dlfcn/tststatic4
FAIL: dlfcn/tststatic5
FAIL: elf/check-localplt
FAIL: elf/tst-relsort1
FAIL: elf/tst-tls9-static
NB: Some of these are static binaries, and running them under GDB with an
explicit dynamic linker invocation causes a different crash.

I would have expected that the LC_ADDRESS language name would have been
localized to Gagana faÊ»a SÄmoa or Gagana SÄmoa.

Bug ID: 21715
Summary: sysdeps/nptl/bits/pthreadtypes.h: typedef guard
__have_pthread_attr_t can cause redefinition of
typedef ‘pthread_attr_t’
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: mkrupcale at matthewkrupcale dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
glibc version: 2.25.90 (commit e78dc67889c35d9a77e043930dc234005cdcbc76)
Host/Built/Target triplet: x86_64-redhat-linux
When compiling Expect 5.45 using this glibc, I receive several errors for the
redefinition of typedef pthread_attr_t:
In file included from /u/krupcale1/glibc/2.25.90/include/signal.h:62,
from expect.c:13:
/u/krupcale1/glibc/2.25.90/include/bits/types/sigevent_t.h:17: error:
redefinition of typedef ‘pthread_attr_t’
/u/krupcale1/glibc/2.25.90/include/bits/pthreadtypes.h:62: note: previous
declaration of ‘pthread_attr_t’ was here
On inspection, it seems that the typedef guard in
/u/krupcale1/glibc/2.25.90/include/bits/pthreadtypes.h, which I presume is
coming from the shared pthread definition file
'sysdeps/nptl/bits/pthreadtypes.h', has the wrong #define:
61 #ifndef __have_pthread_attr_t
62 typedef union pthread_attr_t pthread_attr_t;
63 # define __have_pthread_attr_t1
64 #endif
[Note there is no space between the token (__have_pthread_attr_t) and value
(1)].
On further inspection, this error actually seems to stem from the initial
AArch64 implementation. Its general history is summarized as follows:
Date Commit

2017-04-04 15:51:10 -0300 eab380d8ec9884e90232dceba24161e63ddd26b8

AArch64 Port
Thus, since commit eab380d8ec9884e90232dceba24161e63ddd26b8 it can show up in
other architectures as well, now that there is a shared typedef of
pthread_attr_t.

I sent a RFC patch for these errors:
https://sourceware.org/ml/libc-alpha/2017-07/msg00171.html
These errors only happen when using a Binutils supporting Power ISA 3.0
instructions and GCC 7 or trunk with rev. >= 246043.

I'm handing this to Adhemerval to review since he refactored this code. Please
unassign it if you won't get to look at this before we release 2.26.

--- Comment #13 from Gunnar Hjalmarsson <gunnarhj at ubuntu dot com> ---
Seeing at other bug reports that some updates have been made recently to comply
with CLDR, and it would be great if someone could revisit this one and change
the language name to "Bangla" as originally requested. As already stated, the
change has been made in CLDR.

Bug ID: 21716
Summary: Crash in glibc's mktime in low-memory situations
Product: glibc
Version: 2.19
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: time
Assignee: unassigned at sourceware dot org
Reporter: sourceware at sagamusix dot de
Target Milestone: ---
Originally reported with all the details on the Debian bugtracker:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=867283
glibc uses the function __tzstring to allocate strings in various time-related
places, but does not guard against out-of-memory situations sufficiently.
__tzstring uses malloc internally and subsequently may return NULL if the
memory allocation failed. The result of __tzstring should be verified so that
later assumptions about strings being non-NULL are not violated. In this
particular case, an assertion was violated and consequently caused a SIGABRT,
which violates the API contract of mktime (it should return -1 on failure, and
when used in C++ it is guaranteed to be exception-safe).
This bug was found with American Fuzzy Lop and libdislocator.

--- Comment #3 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
I think the patch is correct, although a more aligned approach to current glibc
practices would be to have the 'pthread_attr_t' in its own header in 'types'
subfolder . Given current 2.26 code freeze I think the patch in comment #2 is
the more feasible. I will prepare it and send upstream.

Of course, since sizeof >= alignof, the MAX is unnecessary and it could just
use sizeof.

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<sys/cet.h> is added so that it can be included by assembly codes to
add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

--- Comment #5 from Chris Leonard <cjlhomeaddress at gmail dot com> ---
I think this locale file may need to define the sort order. I not 100% sure,
but I would be surprised if the default ordering includes the fairly unique
ʻokina character (glottal stop) appearing only in Polynesian languages(and
variably encoded even there). I think you may need to include U+02BB

Patch for optimizing merge sort
This patch improves the performance of merge sort used by qsort in stdlib of
glibc .
When the elements are already sorted or almost sorted , it improves performance
of merge procedure by skipping comparison and copying of elements
when last element of first array and first element of second array is already
sorted .

(1) Worst case when elements are already sorted.
#define N 100000000
long a[N];
int cmpfn (const void * a, const void * b)
{
return ( *(long*)a - *(long*)b );
}
int main()
{
long i;
for (i=0;i<N;i++)
a[i]=i;
qsort(a, N, sizeof(long), cmpfn);
for (i=1;i<N;i++)
{
if(a[i]<a[i-1])
{
printf("Sorting failed\n");
break;
}
}
}
Tested on ARM:

--- Comment #18 from Markus Trippelsdorf <markus at trippelsdorf dot de> ---
It also breaks the build of Chromium
(https://chromium.googlesource.com/breakpad/breakpad/)
All this is annoying and unnecessary churn. You cannot simply break
real world code left and right because some unimportant POSIX conform
tests fail (who cares?).
(and the compiler santizers (compiler-rt) are broken by a similar change:
struct sigaltstack -> stack_t)
Please reconsider.

commit 031e519c95c069abe4e4c7c59e2b4b67efccdee5
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Thu Jul 6 04:43:06 2017 -0700
x86-64: Align the stack in __tls_get_addr [BZ #21609]
This change forces realignment of the stack pointer in __tls_get_addr, so
that binaries compiled by GCCs older than GCC 4.9:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
continue to work even if vector instructions are used in glibc which
require the ABI stack realignment.
__tls_get_addr_slow is added to handle the slow paths in the default
implementation of__tls_get_addr in elf/dl-tls.c. The new __tls_get_addr
calls __tls_get_addr_slow after realigning the stack. Internal calls
within ld.so go directly to the default implementation of __tls_get_addr
because they do not need stack realignment.
[BZ #21609]
* sysdeps/x86_64/Makefile (sysdep-dl-routines): Add tls_get_addr.
(gen-as-const-headers): Add rtld-offsets.sym.
* sysdeps/x86_64/dl-tls.c: New file.
* sysdeps/x86_64/rtld-offsets.sym: Likwise.
* sysdeps/x86_64/tls_get_addr.S: Likewise.
* sysdeps/x86_64/dl-tls.h: Add multiple inclusion guards.
* sysdeps/x86_64/tlsdesc.sym (TI_MODULE_OFFSET): New.
(TI_OFFSET_OFFSET): Likwise.

x86-64: Align the stack in __tls_get_addr [BZ #21609]
This change forces realignment of the stack pointer in __tls_get_addr, so
that binaries compiled by GCCs older than GCC 4.9:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
continue to work even if vector instructions are used in glibc which
require the ABI stack realignment.
__tls_get_addr_slow is added to handle the slow paths in the default
implementation of__tls_get_addr in elf/dl-tls.c. The new __tls_get_addr
calls __tls_get_addr_slow after realigning the stack. Internal calls
within ld.so go directly to the default implementation of __tls_get_addr
because they do not need stack realignment.
[BZ #21609]
* sysdeps/x86_64/Makefile (sysdep-dl-routines): Add tls_get_addr.
(gen-as-const-headers): Add rtld-offsets.sym.
* sysdeps/x86_64/dl-tls.c: New file.
* sysdeps/x86_64/rtld-offsets.sym: Likwise.
* sysdeps/x86_64/tls_get_addr.S: Likewise.
* sysdeps/x86_64/dl-tls.h: Add multiple inclusion guards.
* sysdeps/x86_64/tlsdesc.sym (TI_MODULE_OFFSET): New.
(TI_OFFSET_OFFSET): Likwise.
(cherry picked from commit 031e519c95c069abe4e4c7c59e2b4b67efccdee5)

Arabic scripts: More fixes after the recent import.
After the recent import of month names from CLDRv31 (bug 21217,
commit c853f14) more imports are also needed, mostly abbreviated month
names.
This patch also updates May (full month name) in ps_AF which was
skipped in the previous patch.
Incidentally, this import fixes bug 17225 (ar_SY) and partially
bug 19066 (ar_SA).
CLDR currently has a bug in the full month name for October for ar_IQ, see
http://unicode.org/cldr/trac/ticket/10460
* localedata/locales/ar_DZ (abmon): Full import from CLDR, abmon
is no longer abbreviated.
* localedata/locales/ar_IQ (abmon): Likewise.
* localedata/locales/ar_MA (abmon): Likewise.
* localedata/locales/ar_TN (abmon): Likewise.
* localedata/locales/ps_AF (abmon): Likewise.
* localedata/locales/ug_CN (abmon): Likewise.
* localedata/locales/ar_SA (abmon): Likewise, partially
fixes bug 19066.
* localedata/locales/ks_IN (abmon): A copy of mon.
* localedata/locales/ur_IN (abmon): Oct reworded "اكتوبر" to
"اکتوبر" (same change as mon).
* localedata/locales/ur_PK (abmon): Same changes as mon applied.
* localedata/locales/ps_AF (mon): May reworded "Ù…ÛŒ" to "Ù…Û".
[BZ #17225]
* localedata/locales/ar_SY (abmon): May reworded "نوار" to
"أيار", this closes bug 17225.
* localedata/locales/ar_JO (abmon): Likewise.
* localedata/locales/ar_LB (abmon): Likewise.

commit 1bea5858dd5b2615288e96525f3918e35f42dd2d
Author: Rafal Luzynski <digitalfreak@lingonborough.com>
Date: Sat Jul 1 02:22:37 2017 +0200
Arabic scripts: More fixes after the recent import.
After the recent import of month names from CLDRv31 (bug 21217,
commit c853f14) more imports are also needed, mostly abbreviated month
names.
This patch also updates May (full month name) in ps_AF which was
skipped in the previous patch.
Incidentally, this import fixes bug 17225 (ar_SY) and partially
bug 19066 (ar_SA).
CLDR currently has a bug in the full month name for October for ar_IQ, see
http://unicode.org/cldr/trac/ticket/10460

And ucontext_t also works for older glibcs, so #ifdefs aren't necessary.
Therefore I retract my objection.

Bug ID: 21731
Summary: Bad malloc heuristic result in 30-40x memory
consumption
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: yyc1992 at gmail dot com
Target Milestone: ---
Created attachment 10251
--> https://sourceware.org/bugzilla/attachment.cgi?id=10251&action=edit
Compressed source code
The program attached is created from a log of a program that has a loop that
allocates and free large chunks of memory (the `posix_memalign`s) while at the
same time "leaks" small objects. The memory leak per loop is ~1.6kB. However
running this (may need to compile with `-O0` to make the compilation finish in
reasonable amount of time and to avoud compiler removing allocations) with
glibc malloc implementation results in a `malloc_stats` output that ends up
like
```
Arena 0:
system bytes = 2498392064
in use bytes = 68811392
Total (incl. mmap):
system bytes = 2512826368
in use bytes = 83245696
max mmap regions = 10
max mmap bytes = 67239936
```
in ~100 cycles which I believe indicates that the allocation is not reusing
memory. The `in use bytes` reflects the actual allocation in the loops but the
growth in `system bytes` (and total memory consumption) increases at roughly
the same rate as the large allocation in the loop even though it's free'd in
the next loop as indicated by `in use bytes`.

Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal

Created attachment 10246
--> https://sourceware.org/bugzilla/attachment.cgi?id=10246&action=edit
Specially crafted demo "exploit" program, ELF x86_64
I think I have found a potential security issue on the operating
system where an aware attacker could execute a specially crafted ELF
file in the normal user privilege via explicitly invoking the loader
even when the eXecute permission is missing in its file mode and/or
the `noexec' flag is set on the mountpoint containing the executable.
This issue has quite been a traditional one, with an older, similar
issue (only involving the direct ld invocation) having been patched at
the kernel level by denying mmap PROT_EXEC requests on non-executable
files with EPERM. What this issue differs from that is an extra layer
atop the binary involving relocations (preferably R_<arch>_COPY) on a
executable "BSS" segment which enables us to inject executable codes
without ever mmap'ing an executable page from the original executable
file.
Although I do not see any severe security issues as this cannot affect
`setuid' or existing executables that cannot be modified by the
attacker, I think it may be worth patching since it may help prevent
some obscure attacks on a few specific secure configurations, and
doing so would make it consistent with existing behavior of the
loader.
The attached `test-program' executable, crafted for demonstration,
uses the AMD64 architecture and can be invoked as-is or directly using
the loader in a form like `/lib64/ld-linux-x86-64.so.2 ./test-program'
. It contains a simple code which issues the execve() system call to
invoke a shell on the system.

--- Comment #4 from Mike FABIAN <maiku.fabian at gmail dot com> ---
+yesstr "是"
+nostr "没有"
I asked a colleague (Peng Wu <pwu@redhat.com>) who is a native speaker
of Chinese and he said the yesstr is OK but the nostr should be "ä¸æ˜¯".
I committed that change with him as the author.

Why is DT_TEXTREL needed?
I think we need support for an O_FOREXEC flag from the kernel. Script
interpreters could use that, too.

Bug ID: 21735
Summary: open_memstream is not fflushed with fflush(0)
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: nszabolcs at gmail dot com
Target Milestone: ---
open_memstream is not exempt from the rule that fflush(0)
should fflush all open streams.
posix specifies the state of the buffer and size after
fflush on a stream opened by open_memstream and glibc
is not conform to it, e.g the following test fails:
#include <stdio.h>
int main()
{
char *buf = 0;
size_t n = 0;
FILE *f = open_memstream(&buf, &n);
putc('x', f);
fflush(0);
return n != 1;
}

It was just because I personally did not want an RWX area in the virtual
memory, nothing more. Apologizes if it had caused any confusion.
And for the O_FOREXEC flag, you do have the point.

Please make sure that the bugs you've resolved as FIXED lately have their
target milestones properly set (to the first mainline release with the
fix, i.e. 2.26), so that they appear in the automatically-generated list
of fixed bugs in NEWS.

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<sys/cet.h> is added so that it can be included by assembly codes to
add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

commit 254f4b11c853f4a3999d194c7b56327584e2b515

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

--- Comment #6 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Note that when marking bugs as FIXED, you should also set the target
milestone to the first mainline version with the fix (so 2.26 in this
case), as that's used to generate the list of fixed bugs for the NEWS file
and release announcement.

Bug ID: 21744
Summary: Tests failing on --enable-tunables
--enable-stack-protector=all
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: tuliom at linux dot vnet.ibm.com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
The following tests fail when configuring glibc with
--enable-stack-protector=all on glibc master.
cat elf/tst-env-setuid.out
Unexpected exit status 0 from child process
cat elf/tst-env-setuid-tunables.out
Unexpected exit status 0 from child process
cat stdlib/tst-secure-getenv.out
Unexpected exit status 11 from child process
Disabling the tunables framework, which is enabled by default, make these tests
pass.
Confirmed on ppc64le and x86_64.

Add __stack_chk_fail_local alias only to libc.so [BZ #21740]
commit 524a8ef2ad76af8ac049293d993a1856b0d888fb
Author: Nick Alcock <nick.alcock@oracle.com>
Date: Mon Dec 26 10:08:57 2016 +0100
PLT avoidance for __stack_chk_fail [BZ #7065]
Add a hidden __stack_chk_fail_local alias to libc.so,
and make sure that on targets which use __stack_chk_fail,
this does not introduce a local PLT reference into libc.so.
unconditionally added
strong_alias (__stack_chk_fail, __stack_chk_fail_local)
Since libc.a and libc_nonshared.a has debug/stack_chk_fail_local.c,
__stack_chk_fail_local alias should be limited to libc.so.
Tested on x86-64 with --enable-stack-protector=all and got
FAIL: elf/tst-env-setuid
FAIL: elf/tst-env-setuid-tunables
FAIL: stdlib/tst-secure-getenv
which are the same as without this patch.
[BZ #21740]
* debug/stack_chk_fail.c (__stack_chk_fail_local): Add the
alias only if SHARED is defined.

commit 217275043ad73f922d07f42e5fc1a4be70183209

Add __stack_chk_fail_local alias only to libc.so [BZ #21740]
commit 524a8ef2ad76af8ac049293d993a1856b0d888fb
Author: Nick Alcock <nick.alcock@oracle.com>
Date: Mon Dec 26 10:08:57 2016 +0100
PLT avoidance for __stack_chk_fail [BZ #7065]
Add a hidden __stack_chk_fail_local alias to libc.so,
and make sure that on targets which use __stack_chk_fail,
this does not introduce a local PLT reference into libc.so.
unconditionally added
strong_alias (__stack_chk_fail, __stack_chk_fail_local)
Since libc.a and libc_nonshared.a has debug/stack_chk_fail_local.c,
__stack_chk_fail_local alias should be limited to libc.so.
Tested on x86-64 with --enable-stack-protector=all and got
FAIL: elf/tst-env-setuid
FAIL: elf/tst-env-setuid-tunables
FAIL: stdlib/tst-secure-getenv
which are the same as without this patch.
[BZ #21740]
* debug/stack_chk_fail.c (__stack_chk_fail_local): Add the
alias only if SHARED is defined.

Avoid backtrace from __stack_chk_fail [BZ #12189]
__stack_chk_fail is called on corrupted stack. __stack_chk_fail should
use as little stack as possible. __libc_message is extended to avoid
calling BEFORE_ABORT when do_abort >= 3 and __fortify_fail_abort is
added to avoid backtrace from __stack_chk_fail.
[BZ #12189]
* debug/Makefile (CFLAGS-tst-ssp-1.c): New.
(tests): Add tst-ssp-1 if -fstack-protector works.
* debug/fortify_fail.c (_fortify_fail_abort): New function.
(__fortify_fail): Call _fortify_fail_abort.
(__fortify_fail_abort): Add a hidden definition.
* debug/stack_chk_fail.c (__stack_chk_fail): Call
__fortify_fail_abort, instead of __fortify_fail.
* debug/tst-ssp-1.c: New file.
* include/stdio.h (__fortify_fail_abort): New hidden prototype.
* sysdeps/posix/libc_fatal.c (__libc_message): Call BEFORE_ABORT
if do_abort < 3.

commit 37900e7dee18a446afda1b9e9831cd3d331f2a4f
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Mon Jul 10 12:21:39 2017 -0700
Avoid backtrace from __stack_chk_fail [BZ #12189]
__stack_chk_fail is called on corrupted stack. __stack_chk_fail should
use as little stack as possible. __libc_message is extended to avoid
calling BEFORE_ABORT when do_abort >= 3 and __fortify_fail_abort is
added to avoid backtrace from __stack_chk_fail.
[BZ #12189]
* debug/Makefile (CFLAGS-tst-ssp-1.c): New.
(tests): Add tst-ssp-1 if -fstack-protector works.
* debug/fortify_fail.c (_fortify_fail_abort): New function.
(__fortify_fail): Call _fortify_fail_abort.
(__fortify_fail_abort): Add a hidden definition.
* debug/stack_chk_fail.c (__stack_chk_fail): Call
__fortify_fail_abort, instead of __fortify_fail.
* debug/tst-ssp-1.c: New file.
* include/stdio.h (__fortify_fail_abort): New hidden prototype.
* sysdeps/posix/libc_fatal.c (__libc_message): Call BEFORE_ABORT
if do_abort < 3.

Bug ID: 21750
Summary: column width of characters incompatible with classical
wcwidth
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: tg at mirbsd dot de
CC: libc-locales at sourceware dot org
Target Milestone: ---
I’ve compared the new autogenerated column width from
localedata/unicode-gen/utf8_gen.py with the results of the classical wcwidth()
implementation from xterm (adjusted to Unicode 10.0.0) and found a few
divergences (and bugs on my (MirBSD, which uses something based on xterm’s data
system-wide) side, which I fixed).
1. U+00AD is forced to width 1 in xterm, autodetected as combining in glibc
Rationale for forcing it to 1 is likely that U+0000‥U+00FF are latin1, which,
when displayed as 8bit on terminals, had no combining characters at all.
Change Request to glibc: force U+00AD to width 1.
2. The UCD has three codepoints that are Me/Mn category but not NSM bidi class:
U+0CBF U+0CC6 U-00011C3F
This is likely a bug in UCD but can be fixed by glibc treating Me/Mn the same
as Cf/NSM, which I do.
Change Request to glibc: handle Me/Mn category the same as NSM bidi class.
3. Hangul Jamo medial vowels and final consonants are set to 0 by xterm so they
combine on top of the preceding initial ones: U+1160‥U+11FF
Change Request to glibc: force U+1160‥U+11FF to width 0.
4. During parsing, EastAsianWidth data overrides UCD data, more specifically
the NSM property.
This leads to U+302A‥U+302D and – see also
https://sourceware.org/bugzilla/show_bug.cgi?id=19852 – U+3099 and U+309A being
treated as width 2.
Change Request to glibc: read EAW before UCD so the NSM overrides EAW here.
5. Ambiguous circled numbers and neutral hexagrams changed width
xterm used to set those to width 2, likely because they are ideographs and not
unlike zodiac signs and emoji (which, I notice, have been set to width 2 in UCD
nowadays)
Change Request to glibc: force U+3248‥U+324F and U+4DC0‥U+4DFF to width 2.
Note: I’ve initially reported the surprising change to Debian as
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=826256 but have redone the
research today (against 2.24 in Debian and git master commit
2a91300176a5991d9825eba085e502196a3f47cd in glibc) against Unicode 10,
double-checked *all* differences against MirBSD code and fixed a few bugs there
after making it possible to compare the results (considering glibc only puts
actually assigned codepoints into the localedata/charmaps/UTF-8 file).
Rationale for requesting the change in glibc is so that all systems I have
access to use the same width data, preventing display artifacts and glitches up
to making an editor somewhat unusable with heavy Unicode (I have test files
containing the entire Unicode range). Thank you for listening.
If necessary, I will provide patches (to utf8_gen.py most likely) when asked.

--- Comment #6 from Thorsten Glaser <tg at mirbsd dot de> ---
I’ve filed https://sourceware.org/bugzilla/show_bug.cgi?id=21750 noting _all_
differences from Markus Kuhn’s xterm code (updated for Unicode 10) to the
current glibc localedata.
For this particular problem, the fix is easy (interestingly enough, I had a
similar bug in MirBSD when redoing the wcwidth code): read EastAsianWidth
before, not after, UnicodeData, so the NSM bidi class overrides the width set
by the former.

Avoid backtrace from __stack_chk_fail [BZ #12189]
__stack_chk_fail is called on corrupted stack. Stack backtrace is very
unreliable against corrupted stack. __libc_message is changed to accept
enum __libc_message_action and call BEFORE_ABORT only if action includes
do_backtrace. __fortify_fail_abort is added to avoid backtrace from
__stack_chk_fail.
[BZ #12189]
* debug/Makefile (CFLAGS-tst-ssp-1.c): New.
(tests): Add tst-ssp-1 if -fstack-protector works.
* debug/fortify_fail.c: Include <stdbool.h>.
(_fortify_fail_abort): New function.
(__fortify_fail): Call _fortify_fail_abort.
(__fortify_fail_abort): Add a hidden definition.
* debug/stack_chk_fail.c: Include <stdbool.h>.
(__stack_chk_fail): Call __fortify_fail_abort, instead of
__fortify_fail.
* debug/tst-ssp-1.c: New file.
* include/stdio.h (__libc_message_action): New enum.
(__libc_message): Replace int with enum __libc_message_action.
(__fortify_fail_abort): New hidden prototype.
* malloc/malloc.c (malloc_printerr): Update __libc_message calls.
* sysdeps/posix/libc_fatal.c (__libc_message): Replace int
with enum __libc_message_action. Call BEFORE_ABORT only if
action includes do_backtrace.
(__libc_fatal): Update __libc_message call.

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
The 'system bytes' field from malloc_stats reports the main arena size which is
size requested with 'sbrk'. And since you are explicit 'leaking' memory, most
likely it requires to continually grow the main arena virtual memory due
fragmentation. Keep in mind that although it does increases the maximum
virtual memory of the process, it does not actually increase the total RSS
usage.
Using the same example, if you intercept malloc_stat to print total RSS usage
using this naive approach:
---
$ cat intercept.c
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>
void malloc_stats (void)
{
//system ("cat /proc/self/status | grep -E '^Vm(RSS|Data)'");
system ("cat /proc/self/status | grep -E '^VmRSS'");
}
$ gcc -Wall intercept.c -shared -o libintercept.so -fpic
$ LD_PRELOAD=./libintercept.so ./malloc
---
You will see that total RSS usage does not really change significantly. For
instance, a run I am seeing:
---
$ LD_PRELOAD=./libintercept.so ./malloc
VmRSS: 708 kB
VmRSS: 744 kB
[...]
VmRSS: 860 kB
VmRSS: 696 kB
[...]
VmRSS: 708 kB
VmRSS: 796 kB
---
Also you can change the sbrk behavior and force mmap allocations for large
sizes on main arena using MALLOC_TOP_PAD_=0:
---
$ MALLOC_TOP_PAD_=0 ./malloc
Arena 0:
system bytes = 16076800
in use bytes = 15697952
Total (incl. mmap):
system bytes = 57049088
in use bytes = 56670240
max mmap regions = 10
max mmap bytes = 41500672
[...]
Arena 0:
system bytes = 16076800
in use bytes = 15879792
Total (incl. mmap):
system bytes = 83451904
in use bytes = 83254896
max mmap regions = 12
max mmap bytes = 67903488
---
Now, what do you mean by 'bad heuristic' and by 'memory consumption' in this
specific case?

I'm seeing (at least in the original program) that the system memory usage is
going up and the max rss of the process too.

And this does not seem to be a GLIBC issue based on the example provided. Also,
if you ran the example on valgrind you see it does have a lot of actual memory
leaks (which I am not sure if they are intentional or not for the example
itself).

It is, since the memory consumption (measured by overall system memory usage
and also the maxrss of the process) grows much faster than what the actual
accumulated memory does (by more than 100x).
> Also, if you ran the example on valgrind you see it does have a lot of actual memory leaks (which I am not sure if they are intentional or not for the example itself).
Yes it will obviously detect leaks since the program does not free all the
memory it allocates. As mentioned in the original report and above though, that
small amount of accumulated allocation is causing a much higher memory
consumption increase (measured by overall system memory usage and also the
maxrss of the process).

```
system ("cat /proc/self/status | grep -E '^VmRSS'");
```
FWIW, I think this is reading the status of the `cat`.

Right, my mistake here. However fix this:
---
$ cat intercept.c
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
void malloc_stats (void)
{
pid_t pid = getpid ();
char line[128];
snprintf (line, 128, "cat /proc/%d/status | grep -E '^VmRSS'", (int) pid);
system (line);
}
---
does show RSS increase:
$ LD_PRELOAD=./libintercept.so ./malloc
VmRSS: 33220 kB
VmRSS: 33420 kB
VmRSS: 35468 kB
[...]
VmRSS: 61108 kB
VmRSS: 61184 kB
VmRSS: 61184 kB
However it is roughly what valgrind shows as leaked memory:
==18794== LEAK SUMMARY:
==18794== definitely lost: 54,274,581 bytes in 75,230 blocks
==18794== indirectly lost: 0 bytes in 0 blocks
==18794== possibly lost: 65,536 bytes in 1 blocks
==18794== still reachable: 0 bytes in 0 blocks
==18794== suppressed: 0 bytes in 0 blocks

--- Comment #7 from Yichao Yu <yyc1992 at gmail dot com> ---
I'm seeing the same with the simplified program now so I guess there are other
libc calls that I'm not recording. I'm still fairly certain that this is glibc
related since the `/proc/self/maps` of the real process shows that the only
growing memory is the heap and no other part of the program is touching the
heap directly and the actual accumulation of allocation is much slower than the
grow rate.
For the simplified case, I'm seeing a large heap usage that's bigger than rss
so I assume glibc calls certain functions to discard the pages without
releasing the VM (madvice?) and it seems that this could be what didn't work in
the real program.

--- Comment #8 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
The main problem is the example you provided is *leaking* memory and using this
an a driver to state that glibc is resulting in increase memory consumption
does not make sense. Either you need to provide an example that does not leak
memory and thus shows that this is indeed an internal glibc issue or fix it in
your program.

--- Comment #9 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
So, how representative is this testcase related to the program in question?
Does the program also shows the same leak misbehavior as the testcase? Did you
ran your program using a memory profile to make sure it is indeed not leaking
memory (valgrind, lsan, etc.)?

--- Comment #10 from Yichao Yu <yyc1992 at gmail dot com> ---
As I said in the very first post, the program does have a small "leak".
However, I think it is reasonable to expect that if the program allocate <100kB
per loop, the peak memory consumption (measured by overall system memory usage
and also the maxrss of the process) should not grow 10x or 100x faster than
this "leak". It is perfectly valid in a program to accumulate small allocations
overtime until they are free'd later. Being able to return to the same memory
consumption (measured in whatever way) is not the only measure of a bug-free
memory manager, the ratio between the peak memory usage and the memory actually
needed is too.

You can have an application that allocates a cache and does not free the cache.
So from the glibc allocator perspective it is not leaking memory, it's just not
being returned because it could be in use. So asking for a perfect program that
doesn't leak just results in a slightly altered test case that has roughly the
same semantics anyway.
The question that remains is:
Where is the memory going?
* external/internal malloc fragmentation?
* program requirements growing with time?
* an application leak?
You have to answer one of these three questions.
For example see:
https://sourceware.org/glibc/wiki/389-ds-malloc
It is not a trivial analysis.
A leak of ~1.6k/loop shows up when you graph the results as a slop in your RSS
consumption. You need to be able to analyze that graph and take into account
the various changes in your application usage.
DJ Delorie and I have done several of these analyses for larger applications
and we have used the malloc simulator and tooling to produce graphs to help
users understand the application memory usage.
I have my own tooling here:
https://pagure.io/glibc-malloc-trace-utils
Then on dj's dj/malloc branch, we have the trace and simulator code (in malloc/
directory) that lets you capture a malloc workload, and then re-run it outside
of your application environment over and over again to look at the behaviour
against various tunables.
I would start by graphing the exact memory usage your application requests for
each API call and see what that looks like e.g. sum after every call.
Then graph the program growth in VmRSS and VmSize and see how the two lines
relate. The VmRSS growth should be linearly dependent upon the requests, and if
it's not then you have to be able to answer the question about about where the
memory is going.

Again your example is a bad one to try show any point. As from my comment #6
RSS at end of execution is roughly 61MB and valgrind is showing a memory leak
of 54MB. This is hardly '10x' increase and it shows more an issue of the
workload/example than on GLIBC.
I think you might not be clear here and using 'memory consumption' as virtual
memory increase. If you check VMSize from /proc/<pid>/status it does increase
over time:
VmSize: 81920 kB
VmSize: 107704 kB
[...]
VmSize: 1164740 kB
VmSize: 1190520 kB
But this does not actually count as actual memory consumption (RSS) and this is
indeed an issue for your program (since it does seems to generate a lot of
memory fragmentation due the leaks). One option could use the MALLOC_TOP_PAD_
(environment variable) / M_TOP_PAD (mallopt). This will avoid the arena
fragmentation by forcing mmap allocations over sbrk:
# this is greping VmSize instead
$ LD_PRELOAD=./libintercept.so MALLOC_TOP_PAD_=0 ./malloc
VmSize: 81376 kB
VmSize: 107160 kB
VmSize: 107160 kB
VmSize: 107160 kB
VmSize: 107160 kB
VmSize: 107160 kB
VmSize: 107160 kB
VmSize: 107160 kB
VmSize: 107160 kB
VmSize: 107160 kB
VmSize: 107160 kB
[...]
VmSize: 107160 kB
GLIBC memory allocation will try to coalesce memory on newer allocations, but
fragmentation might impede and thus why the increase of virtual memory
allocation (some information on the algorithm used can be found at section
'Malloc Algorithm' [1]).
For the workload in question, are these 'leak' intentional? If it the case it
could be a better strategy to create a different allocation strategy, for
instance a external memory poll.

And that was not clear neither from the initial bug report nor on subsequent
comments. Neither in original project bug report I could get some insight from
these initial '~1.6kb' leaks came from of for what the memory is used. So I
assumed that this indeed a faulty memory leak.

Thanks for the summary Carlos, I think this is pretty much the information lack
we need to move forward.

Where is what memory going.
The small actual allocation can be treated as "program requirements growing
with time?" for all purpose in this report. The large growth in overall
consumption (measured by overall system memory usage and also the maxrss of the
process) is exactly what this bug report is about.
> It is not a trivial analysis.
I agree, and thanks for the pointer to the branches/tools, I will try those.
> Again your example is a bad one to try show any point. As from my comment #6 RSS at end of execution is roughly 61MB and valgrind is showing a memory leak of 54MB. This is hardly '10x' increase and it shows more an issue of the workload/example than on GLIBC.
I agree and I've already acknowledged that the code I attached does not seem to
reproduce the original issue, which does have a effect on actual memory
consumption measured with multiple ways.
> I think you might not be clear here and using 'memory consumption' as virtual memory increase.
No. I think I might not be clear enough when I switched from talking about the
behavior of the simplified program, which doesn't show increase in rss, to
talking about the actual program, which does. And I'm now basically asking for
help to figure out what's missing to reproduce it.
> GLIBC memory allocation will try to coalesce memory on newer allocations, but fragmentation might impede and thus why the increase of virtual memory allocation (some information on the algorithm used can be found at section 'Malloc Algorithm' [1]).
So I guess I might be able to find this info out by reading the link in the
previous comment but is there a simple way to dump the heap map? Last time I
check it's consistent with glibc leaving the big hole unfilled but it'll be
nice if I can verify that.

Bug ID: 21752
Summary: __stack_chk_fail should do as little work as possible
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Flags: security+
The fix for bug 12189 only removed the backtrace. We still flush the stdio
streams, which can actually perform indirect function calls. There might be
other things we should remove. We should not call anything but write(v),
sigaction/sginal, getpid and kill.
Tagging security+ in accordance with bug 12189.

Unfortunately we don't have a good heap dumper. DJ had a heap dump visualizer,
but we haven't developed it beyond prototype. We are open to any suggestions
about how best to handle this, but so much application specific information is
required that you need to write custom tooling to help you. The graphing octave
code I have is the most generic examples I could come up with that I use every
time I have to analyze something like this for a user.

--- Comment #4 from Florian Weimer <fweimer at redhat dot com> ---
Could we use a bunch of volatile stack variables for this instead? I'm not
sure if it is such a good idea to call malloc (via asprintf) from assert.
Ideally, assert should be async-signal-safe as a quality-of-implementation
matter.

Bug ID: 21753
Summary: malloc: Document assert redefinition and allign with
<assert.h>
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
malloc needs to redefine assert because glibc's assert implementation itself
calls asprintf (see bug 10217) which in turn calls malloc. This should be
explained in a comment. See bug 10560.
The definition of that assert macro should use the same statement expression
with an if statement as <assert.h>, to catch coding errors within malloc.

Bug ID: 21754
Summary: malloc: Perform as little work as possible after heap
consistency check failures
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
We currently perform a backtrace, flush stdio buffers (via abort), do string
processing, and so on. There appear to be exploitation techniques which abuse
the current behavior.
This will allow us to remove the corrupted arena handling code. It is
reportedly buggy.

--- Comment #2 from Florian Weimer <fweimer at redhat dot com> ---
I think this is important security hardening, hence flagging as security+.
At the very least, we should only do this for actual file-based streams (with
known vtables), not those resulting from open_memstream or fopencookie.

When using “copy "es_PE"†in LC_ADDRESS, the lang_name becomes Español.
Therefore I think adding this is better:

--- Comment #1 from Troy Korjuslommi <tjk at tksoft dot com> ---
Excuse my ignorance, but isn't U+00AD (soft hyphen) usually invisible,
i.e. zero columns? If an app breaks up words at end-of-line, it can use
the soft hyphens as helpers to detect the correct locations. The app can
then add a visible hyphen to the end of the line. (If the app also reads
from the terminal, then it can e.g. ignore visible hyphens when preceded
by a soft hyphen, or use some other mechanism to mark the character as
for terminal display only).
I am not suggesting a change, if xterm etc. multitude of apps are
already handling soft hyphens in some other manner, just wondering.

I see no such failures with master on x86_64, when configuring master with a
reasonably normal set of flags that includes --enable-stack-protector=all (GCC
6.4.1, binutils 2.28, hardware is Broadwell with AVX2):
CFLAGS="-O2 -march=native -pipe -fomit-frame-pointer" ASFLAGS="-O2
-march=native -pipe" CONFIG_SITE= ../glibc/configure
--build=x86_64-pc-linux-gnu --prefix=/usr --enable-shared --enable-kernel=4.1
--enable-check-abi=warn --disable-werror --enable-stack-protector=all
Summary of test results:
4186 PASS
21 UNSUPPORTED
25 XFAIL
6 XPASS
Could you get a backtrace from one of the crashes?

--- Comment #2 from Thorsten Glaser <tg at mirbsd dot de> ---
(In reply to Troy Korjuslommi from comment #1)
> Excuse my ignorance, but isn't U+00AD (soft hyphen) usually invisible,
> i.e. zero columns? If an app breaks up words at end-of-line, it can use
> the soft hyphens as helpers to detect the correct locations. The app can
Yes, in theory. This codepoint could be used in the *input data* to
determine soft breaks. However (see below) they should *not* output
those to a terminal emulator (GUIs that handle this themselves are
likely fine).
> I am not suggesting a change, if xterm etc. multitude of apps are
> already handling soft hyphens in some other manner, just wondering.
Similar to U+0060 (the gravis accent 「`ã€) however, terminal emulators
have been treating both ASCII (for U+0060) and 8-bit codepages like
ISO 8859-1 (for U+00AD) as each (non-control) character having a constant
width of 1 (for SBCS), and xterm’s wcwidth() code had special handling
to force U+00AD to 1:
/*
[…]
* - SOFT HYPHEN (U+00AD) has a column width of 1.
[…]
*/
[…]
/* generated by "uniset +cat=Me +cat=Mn +cat=Cf -00AD +1160-11FF +200B c" */
Source:
http://www.mirbsd.org/cvs.cgi/X11/xc/programs/xterm/wcwidth.c?rev=1.1.103.1;content-type=text%2Fplain
So you’d want to output U+0060 U+0008 U+0061 (` + backspace + a) to get à on a
(printed) terminal (or in code that uses such to emulate them), and similarily,
strip soft hyphens from the output (or manifest them as regular ones) before
outputting a soft-wrapped text (mostly because the terminal emulator will also
not soft-wrap, it’ll break at the end of the line, so you’d convert U+00AD to
some kind of hyphen (hyphen-minus or U+2010 perhaps) followed by a line
break(âš ) if preparing something fopr terminal output).
I’ve noticed the incompatibilities especially when the hexagrams, one of which
I’m using for UI purposes, changed width, and tried to discover all of them in
order to harmonise the width assumptions the various programs I have access to
use on all systems I use, with classical xterm wcwidth.c as base, since those
widths are the domain of a fixed-cell terminal emulator more than something
else (which can use its own data, if necessary).
I do volunteer to provide patches, here and elsewhere, so that, with the same
UCD version as input, we get consistent output (and I’ve sanity-checked the
output I got before opening this report).

--- Comment #2 from Tulio Magno Quites Machado Filho <tuliom at linux dot vnet.ibm.com> ---
I tested on a Fedora 25 x86_64, with the exact same configuration and I noticed
this they all print "SGID failed: GID and EGID match (1000)".
The following tests are marked as UNSUPPORTED:
UNSUPPORTED: elf/tst-env-setuid

Ignore and remove LD_HWCAP_MASK for AT_SECURE programs (bug #21209)
The LD_HWCAP_MASK environment variable may alter the selection of
function variants for some architectures. For AT_SECURE process it
means that if an outdated routine has a bug that would otherwise not
affect newer platforms by default, LD_HWCAP_MASK will allow that bug
to be exploited.
To be on the safe side, ignore and disable LD_HWCAP_MASK for setuid
binaries.
[BZ #21209]
* elf/rtld.c (process_envvars): Ignore LD_HWCAP_MASK for
AT_SECURE processes.
* sysdeps/generic/unsecvars.h: Add LD_HWCAP_MASK.

commit ceeb0740ed04c48170f9f6f15fef55637ad84e1b
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Tue Mar 7 20:52:04 2017 +0530
Ignore and remove LD_HWCAP_MASK for AT_SECURE programs (bug #21209)
The LD_HWCAP_MASK environment variable may alter the selection of
function variants for some architectures. For AT_SECURE process it
means that if an outdated routine has a bug that would otherwise not
affect newer platforms by default, LD_HWCAP_MASK will allow that bug
to be exploited.
To be on the safe side, ignore and disable LD_HWCAP_MASK for setuid
binaries.
[BZ #21209]
* elf/rtld.c (process_envvars): Ignore LD_HWCAP_MASK for
AT_SECURE processes.
* sysdeps/generic/unsecvars.h: Add LD_HWCAP_MASK.

This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".
The branch, master has been updated
via de895ddcd7fc45caeeeb0ae312311b8bd31d82c5 (commit)
from 8bd8c052e765d626fae1424e2739d009a185a6ba (commit)
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those

commit de895ddcd7fc45caeeeb0ae312311b8bd31d82c5
Author: Szabolcs Nagy <szabolcs.nagy@arm.com>
Date: Wed Jul 12 10:53:13 2017 +0100
Disable single thread optimization for open_memstream
Single thread optimization is valid if at thread creation time the
optimization can be disabled. This is in principle true for all
stream objects that user code can access (and thus needs locking),
using the same internal list as fflush(0) uses. However in glibc
open_memstream is not on that list (BZ 21735) so the optimization
has to be disabled.
* libio/memstream.c (__open_memstream): Set _IO_FLAGS2_NEED_LOCK.
* libio/wmemstream.c (open_wmemstream): Likewise.
* nptl/tst-memstream.c: New.

Bug ID: 21771
Summary: Incorrect value of wcrtomb
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: string
Assignee: unassigned at sourceware dot org
Reporter: luckboy at vp dot pl
Target Milestone: ---
I found bug of wcrtomb for first argument as NULL. If first argument of wcrtomb
is NULL, wcrtomb returns incorrect value. This program shows the problem:
#include <limits.h>
#include <locale.h>
#include <stdio.h>
#include <string.h>
#include <wchar.h>
int main(void)
{
char buf[MB_LEN_MAX];
mbstate_t state;
setlocale(LC_ALL, "en_US.UTF-8");
memset(&state, 0, sizeof(mbstate_t));
printf("%ld\n", (long) wcrtomb(NULL, L'\u0104', &state));
memset(&state, 0, sizeof(mbstate_t));
printf("%ld\n", (long) wcrtomb(buf, L'\u0104', &state));
return 0;
}
Result of this below program:

Based on the documentation, that is correct. If the first argument is NULL,
the character argument is ignored, and the result is one plus the number of
bytes required to return to the initial shift state (so always one for UTF-8).

Fixed via commit and tested with the NSS testsuite upgrade I just posted - the
misalignment exists and is detected on x86-64 also, it just doesn't segfault
there ;-)

Date: Sun Jul 16 12:03:29 2017 -0700
Don't all __access_noerrno with stack protector from __tunables_init [BZ
#21744]
maybe_enable_malloc_check, which is called by __tunables_init, call
__access_noerrno. It isn't problem when maybe_enable_malloc_check is
is in ld.so, which has a special version of __access_noerrno without
stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes maybe_enable_malloc_check to call _dl_access_noerrno
instead. For ld.so or glibc built without stack protector, it is defined
to __access_noerrno. Otherwise a special version of __access_noerrno
without stack protector is used by maybe_enable_malloc_check in libc.a.
Tested on x86-64 with and without --enable-stack-protector=all.
[BZ #21744]
* config.h.in (HAVE_STACK_PROTECTOR): New.
* configure.ac (HAVE_STACK_PROTECTOR): AC_DEFINE if configured
with stack protector.
* configure: Regenerated.
* elf/dl-support.c [HAVE_TUNABLES != 0]: Include <access.c> if
__access_noerrno is defined.
* elf/dl-tunables.c (maybe_enable_malloc_check): Replace
__access_noerrno with _dl_access_noerrno.
* elf/dl-tunables.h [SHARED != 0 || HAVE_STACK_PROTECTOR == 0]
(_dl_access_noerrno): New macro.
[SHARED == 0 && HAVE_STACK_PROTECTOR != 0] (__access_noerrno):
New macro.
[SHARED == 0 && HAVE_STACK_PROTECTOR != 0] (_dl_access_noerrno):
New prototype.
* io/access.c (__access): Don't define if __access_noerrno is
defined.
* sysdeps/mach/hurd/access.c (__access): Likewise.
* sysdeps/unix/sysv/linux/access.c (__access): Likewise.

Bug ID: 21777
Summary: use of pthread_getspecific, pthread_setspecific in a
statically linked program leads to a crash before main
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: bruno at clisp dot org
Target Milestone: ---
Created attachment 10265
--> https://sourceware.org/bugzilla/attachment.cgi?id=10265&action=edit
test program
The attached single-threaded program makes use of pthread_getspecific,
pthread_setspecific. When compiled without "-static", it works fine. When
compiled with "-static", it crashes before entering 'main'.
How to reproduce on x86_64:
$ gcc -Wall -O testfstrcmp.c -static -pthread
$ ./a.out
Segmentation fault (core dumped)
It works when compiled without use of pthread_getspecific, pthread_setspecific:
$ gcc -Wall -O -DAVOID_PTHREAD_KEYS testfstrcmp.c -static -pthread
$ ./a.out
>> main
<< main
Here's the stack trace:
$ gcc -Wall -O -ggdb testfstrcmp.c -static -pthread
$ gdb a.out
(gdb) run
Starting program: /tmp/a.out
Program received signal SIGSEGV, Segmentation fault.
0x0000000000000000 in ?? ()
(gdb) where
#0 0x0000000000000000 in ?? ()

#5 0x0000000000401dba in __libc_start_main ()
#6 0x00000000004008b9 in _start ()
I can also reproduce this crash for other CPUs, using qemu "user mode":
e.g. with mips:
$ mips-linux-gnu-gcc-5 -O -Wall -static testfstrcmp.c -pthread -o
testfstrcmp-mips
$ gdb ~/inst-qemu/2.9.0/bin/qemu-mips
(gdb) run testfstrcmp-mips
Thread 1 "qemu-mips" received signal SIGSEGV, Segmentation fault.

19962 ctx.opcode = cpu_ldl_code(env, ctx.pc);
or with aarch64:
$ aarch64-linux-gnu-gcc-5 -O -Wall -static testfstrcmp.c -pthread -o
testfstrcmp-aarch64
$ gdb ~/inst-qemu/2.9.0/bin/qemu-aarch64
(gdb) run testfstrcmp-aarch64

--- Comment #1 from Bruno Haible <bruno at clisp dot org> ---
Note that some functions, such as getpwuid, produce a warning
"warning: Using 'getpwuid' in statically linked applications requires at
runtime the shared libraries from the glibc version used for linking"
but in this case, there were no such warnings. Therefore pthread_getspecific
and pthread_setspecific ought to work in a statically linked program.

commit 894a306f953d38ff606c67d15db9ff1b92ab5962
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Sun Jul 16 12:03:29 2017 -0700
Don't all __access_noerrno with stack protector from __tunables_init [BZ
#21744]
maybe_enable_malloc_check, which is called by __tunables_init, calls
__access_noerrno. It isn't a problem when maybe_enable_malloc_check
is in ld.so, which has a special version of __access_noerrno without
stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes maybe_enable_malloc_check to call _dl_access_noerrno
instead. For ld.so or glibc built without stack protector, it is defined
to __access_noerrno. Otherwise a special version of __access_noerrno
without stack protector is used by maybe_enable_malloc_check in libc.a.
Tested on x86-64 with and without --enable-stack-protector=all.
[BZ #21744]
* config.h.in (HAVE_STACK_PROTECTOR): New.
* configure.ac (HAVE_STACK_PROTECTOR): AC_DEFINE if configured
with stack protector.
* configure: Regenerated.
* elf/dl-support.c [HAVE_TUNABLES != 0]: Include <access.c> if
__access_noerrno is defined.
* elf/dl-tunables.c (maybe_enable_malloc_check): Replace
__access_noerrno with _dl_access_noerrno.
* elf/dl-tunables.h [SHARED != 0 || HAVE_STACK_PROTECTOR == 0]
(_dl_access_noerrno): New macro.
[SHARED == 0 && HAVE_STACK_PROTECTOR != 0] (__access_noerrno):
New macro.
[SHARED == 0 && HAVE_STACK_PROTECTOR != 0] (_dl_access_noerrno):
New prototype.
* io/access.c (__access): Don't define if __access_noerrno is
defined.
* sysdeps/mach/hurd/access.c (__access): Likewise.
* sysdeps/unix/sysv/linux/access.c (__access): Likewise.

HI all,
We found a bug in pthread_mutex_lock which may lead to deadlock. See the
analyze below for details.
__pthread_mutex_lock_full in pthread_mutex_lock.c:
while (1)
{
/* Try to acquire the lock through a CAS from 0 (not acquired) to
our TID | assume_other_futex_waiters. */
//oldval=0, and mutex->__data.__lock != 0
if (__glibc_likely ((oldval == 0)
&& (atomic_compare_and_exchange_bool_acq
(&mutex->__data.__lock,
id | assume_other_futex_waiters, 0) == 0)))
break;
//oldval=0, skip
if ((oldval & FUTEX_OWNER_DIED) != 0)
{
}
//oldval=0, skip
if (__glibc_unlikely ((oldval & FUTEX_TID_MASK) == id))
{
}
//oldval=0, put 0|FUTEX_WAITER into lock when mutex->__data.__lock is 0
//from now on, no one could unlock this mutex...
if ((oldval & FUTEX_WAITERS) == 0)
{
if (atomic_compare_and_exchange_bool_acq (&mutex->__data.__lock,
oldval | FUTEX_WAITERS,
oldval)
!= 0)
...
}
...
}
To fix the bug, we should check if oldval=0 before we try to add FUTEX_WAITER
to the lock.
By the way,There are another similar logical error in pthread_mutex_timedlock
which should fix as well.

testcase to reproduce
Compiled with -DTIMED_LOCK could show the bug in pthread_mutex_timelock,
without this option it test pthread_mutex_lock.

This is due to the relocation generated for vfork_compat's branch to
__libc_vfork. This relocation cannot be resolved and the branch instruction

Bug ID: 21780
Summary: hppa: p{read,write}v2 does not set ENOSUP on invalid
flag
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: adhemerval.zanella at linaro dot org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Different than other arches hppa-linux-gnu define different values for ENOTSUP
and EOPNOTSUPP, where the later is a Linux specific one. This leads to
tst-preadwritev{64}v2 tests failures:
$ ./testrun.sh misc/tst-preadvwritev2
error: tst-preadvwritev2-common.c:35: preadv2 failure did not set errno to
ENOTSUP (223)
error: 1 test failures
The straightforward fix is to return ENOTSUP on all p{read,write}v{64}v2
implementations.

I think that is wrong because "li" is a different language than "nds".

That is:
+country_name "Nederland"
+country_post "NL"
I am not sure here.
CLDR has <territory type="NL" draft="unconfirmed">Nedderlannen</territory>
in nds.xml.
And Wikipedia has:
https://nds-nl.wikipedia.org/wiki/Nederlaand
The Wikipedia page uses the spelling “Nederland†once on top of the box
at the top right of the page. But it mostly uses the spelling “Nederlaandâ€.

Don't call __access_noerrno with stack protector from __tunables_init [BZ
#21744]
maybe_enable_malloc_check, which is called by __tunables_init, calls
__access_noerrno. It isn't a problem when maybe_enable_malloc_check
is in ld.so, which has a special version of __access_noerrno without
stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes maybe_enable_malloc_check to call _dl_access_noerrno
instead. For ld.so or glibc built without stack protector, it is defined
to __access_noerrno. Otherwise a special version of __access_noerrno
without stack protector is used by maybe_enable_malloc_check in libc.a.
Tested on x86-64 with and without --enable-stack-protector=all.
[BZ #21744]
* config.h.in (HAVE_STACK_PROTECTOR): New.
* configure.ac (HAVE_STACK_PROTECTOR): AC_DEFINE if configured
with stack protector.
* configure: Regenerated.
* elf/dl-support.c [HAVE_TUNABLES != 0]: Include <dl-tunables.h>
and include <access.c> if __access_noerrno is defined.
* elf/dl-tunables.c (maybe_enable_malloc_check): Replace
__access_noerrno with _dl_access_noerrno.
* elf/dl-tunables.h [SHARED != 0 || HAVE_STACK_PROTECTOR == 0]
(_dl_access_noerrno): New macro.
[SHARED == 0 && HAVE_STACK_PROTECTOR != 0] (__access_noerrno):
New macro.
[SHARED == 0 && HAVE_STACK_PROTECTOR != 0] (_dl_access_noerrno):
New prototype.
* io/access.c (__access): Don't define if __access_noerrno is
defined.
* sysdeps/mach/hurd/access.c (__access): Likewise.
* sysdeps/unix/sysv/linux/access.c (__access): Likewise.

powerpc: Fix float128 IFUNC relocations [BZ #21707]
The patch proposed by Peter Bergner [1] to libgcc in order to fix
[BZ #21707] adds a dependency on a symbol provided by the loader,
forcing the loader to be linked to tests after libgcc was linked.
It also requires to read the thread pointer during IRELA relocations.
Tested on powerpc, powerpc64, powerpc64le, s390x and x86_64.
[1] https://sourceware.org/ml/libc-alpha/2017-06/msg01383.html
[BZ #21707]
* csu/libc-start.c (LIBC_START_MAIN): Perform IREL{,A}
relocations before or after initializing the TCB on statically
linked executables. That's a per-architecture definition.
* elf/rtld.c (dl_main): Add a comment about thread-local
variables initialization.
* sysdeps/generic/libc-start.h: New file. Define
ARCH_APPLY_IREL and ARCH_SETUP_IREL.
* sysdeps/powerpc/Makefile:
[$(subdir) = elf && $(multi-arch) != no] (tests-static-internal): Add
tst-tlsifunc-static.
[$(subdir) = elf && $(multi-arch) != no && $(build-shared) == yes]
(tests-internal): Add tst-tlsifunc.
* sysdeps/powerpc/tst-tlsifunc.c: New file.
* sysdeps/powerpc/tst-tlsifunc-static.c: Likewise.
* sysdeps/powerpc/powerpc64le/Makefile (f128-loader-link): New
variable.
[$(subdir) = math] (test-float128% test-ifloat128%): Force
linking to the loader after linking to libgcc.
[$(subdir) = wcsmbs || $(subdir) = stdlib] (bug-strtod bug-strtod2)
(bug-strtod2 tst-strtod-round tst-wcstod-round tst-strtod6 tst-strrom)
(tst-strfrom-locale strfrom-skeleton): Likewise.
* sysdeps/unix/sysv/linux/powerpc/libc-start.h: New file. Define
ARCH_APPLY_IREL and ARCH_SETUP_IREL.

Don't add stack_chk_fail_local.o to libc.a [BZ #21740]
commit 524a8ef2ad76af8ac049293d993a1856b0d888fb
Author: Nick Alcock <nick.alcock@oracle.com>
Date: Mon Dec 26 10:08:57 2016 +0100
PLT avoidance for __stack_chk_fail [BZ #7065]
Add a hidden __stack_chk_fail_local alias to libc.so,
and make sure that on targets which use __stack_chk_fail,
this does not introduce a local PLT reference into libc.so.
which unconditionally added
strong_alias (__stack_chk_fail, __stack_chk_fail_local)
defines __stack_chk_fail_local as an alias of __stack_chk_fail in libc.a.
There is no need to add stack_chk_fail_local.o to libc.a. We only need
to add stack_chk_fail_local.oS to libc_nonshared.a.
Tested on x86-64:
[hjl@gnu-skl-1 build-x86_64-linux]$ nm libc.a | grep __stack_chk_fail
0000000000000000 T __stack_chk_fail
0000000000000000 T __stack_chk_fail_local
[hjl@gnu-skl-1 build-x86_64-linux]$ nm libc_nonshared.a | grep
__stack_chk_fail_local
0000000000000000 T __stack_chk_fail_local
[hjl@gnu-skl-1 build-x86_64-linux]$
[BZ #21740]
* debug/Makefile (elide-routines.o): New.

commit 47d95763a35fbc83ac871b10fc59f9eca1ef0a40
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Sun Jul 9 08:39:17 2017 -0700
Don't add stack_chk_fail_local.o to libc.a [BZ #21740]
commit 524a8ef2ad76af8ac049293d993a1856b0d888fb
Author: Nick Alcock <nick.alcock@oracle.com>
Date: Mon Dec 26 10:08:57 2016 +0100
PLT avoidance for __stack_chk_fail [BZ #7065]
Add a hidden __stack_chk_fail_local alias to libc.so,
and make sure that on targets which use __stack_chk_fail,
this does not introduce a local PLT reference into libc.so.
which unconditionally added
strong_alias (__stack_chk_fail, __stack_chk_fail_local)
defines __stack_chk_fail_local as an alias of __stack_chk_fail in libc.a.
There is no need to add stack_chk_fail_local.o to libc.a. We only need
to add stack_chk_fail_local.oS to libc_nonshared.a.
Tested on x86-64:
[hjl@gnu-skl-1 build-x86_64-linux]$ nm libc.a | grep __stack_chk_fail
0000000000000000 T __stack_chk_fail
0000000000000000 T __stack_chk_fail_local
[hjl@gnu-skl-1 build-x86_64-linux]$ nm libc_nonshared.a | grep
__stack_chk_fail_local
0000000000000000 T __stack_chk_fail_local
[hjl@gnu-skl-1 build-x86_64-linux]$
[BZ #21740]
* debug/Makefile (elide-routines.o): New.

Bug ID: 21789
Summary: Consider adding reallocarray prototype to stdlib.h to
match *BSD behaviour
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: krejzi at email dot com
Target Milestone: ---
Glibc 2.26 has added reallocarray function to be more compatible with *BSD
libc. On *BSD, reallocarray is declared in stdlib.h, whereas in current glibc
git master it's declared in malloc.h.
This might introduce some compatibility issues when the autoconf snippet that
checks for reallocarray presence assumes reallocarray is declared in stdlib.h.

It already does, you only need to enable it with _GNU_SOURCE via

commit 2f919bf21329d130036d92682ec4cef390f09321
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Fri Jun 23 14:38:46 2017 -0700
Avoid .symver on common symbols [BZ #21666]
The .symver directive on common symbol just creates a new common symbol,
not an alias and the newer assembler with the bug fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21661
will issue an error. Before the fix, we got
$ readelf -sW libc.so | grep "loc[12s]"
5109: 00000000003a0608 8 OBJECT LOCAL DEFAULT 36 loc1
5188: 00000000003a0610 8 OBJECT LOCAL DEFAULT 36 loc2
5455: 00000000003a0618 8 OBJECT LOCAL DEFAULT 36 locs
6575: 00000000003a05f0 8 OBJECT GLOBAL DEFAULT 36 locs@GLIBC_2.2.5
7156: 00000000003a05f8 8 OBJECT GLOBAL DEFAULT 36 loc1@GLIBC_2.2.5
7312: 00000000003a0600 8 OBJECT GLOBAL DEFAULT 36 loc2@GLIBC_2.2.5
in libc.so. The versioned loc1, loc2 and locs have the wrong addresses.
After the fix, we got
$ readelf -sW libc.so | grep "loc[12s]"
6570: 000000000039e3b8 8 OBJECT GLOBAL DEFAULT 34 locs@GLIBC_2.2.5

7307: 000000000039e3c0 8 OBJECT GLOBAL DEFAULT 34 loc2@GLIBC_2.2.5
[BZ #21666]
* misc/regexp.c (loc1): Add __attribute__ ((nocommon));
(loc2): Likewise.
(locs): Likewise.

But it is gone in 2.26. Since it is local, I don't know how it should

__memset_zero_constant_len_parameter should be removed:
commit 61062f56304750c367c5c1533351621353c112a7
Author: Ulrich Drepper <drepper@redhat.com>
Date: Tue Mar 1 00:35:23 2005 +0000
* posix/bits/unistd.h: Avoid calling __*_chk variants if we can
determine the call will never trigger a failure.
* sysdeps/i386/i686/memset_chk.S: Remove alias and warning.
* sysdeps/x86_64/memset_chk.S: Likewise.
2005-02-24 Roland McGrath <roland@redhat.com>
* debug/Versions (libc: GLIBC_2.4): Remove
__memset_zero_constant_len_parameter.
* sysdeps/generic/memset_chk.c: Remove alias and warning.
* misc/sys/cdefs.h (__warndecl): New macro.
* debug/warning-nop.c: New file.
* string/bits/string3.h (memset): Call __warn_memset_zero_len with
no
arguments, instead of calling __memset_zero_constant_len_parameter.
Use __warndecl for __warn_memset_zero_len.
* debug/Makefile (routines): Add $(static-only-routines).
(static-only-routines): New variable.

In August I will send the final version. Came across a few minor bugs in other

(In reply to Andreas Schwab from comment #11)
> How is that relevant? The used gcc has been bootstrapped with 2.25.
Part of the problematic code (the getauxval call) lives in libgcc.a and needs
to be fixed in GCC. The fix (use the hwcap data in the TCB) revealed the need
for *another* change in glibc, regarding TCB initialization in statically
linked binaries.

--- Comment #12 from Carlos O'Donell <carlos at redhat dot com> ---
There is no consensus, and in fact there is opposition to the addition of en_*
locales for all countries that deal with English. Stated reasons include: size
of install, increased number of locales to pick from, complexity on the user
side for selecting those locales (Chris Leonard's "maximum parsimony" theory
;-)). Instead the generally accepted idea is that you should mix-and-match the
LC_* variables as needed, with the knowledge that this is not the most flexible
way to solve this problem. Individual distributions are free to include
whatever en_* locales they wish to build to suit their users. Likewise, users
can do the same thing.
Therefore until there is consensus formed around this issue I'm marking this
bug as RESOLVED/WONTFIX.

I failed to mention that Mike Frysinger's suggestion of a new way to
mix-and-match language/territory is probably the right place to start for a
solution to this problem that doesn't include new locales.

> Something that fixes this crash.
If I understand correctly you have:
- gcc7-7.1.1+r249772-1.2 (bootstrapped with 2.25)
- binutils 2.28?
- glibc master (soon to be glibc 2.26).
The fix in glibc master is not designed to solve the bootstrap problem because
such a fix would be too complex during a freeze. In order to fix this fully in
glibc we would have to, for ppc64le, refactor the initialization of the
getauxval data to happen before IFUNC resolvers are run.
Instead the suggested solution for distributions is as follows:
* Backport the fix by Peter Bergner:
https://gcc.gnu.org/ml/gcc-patches/2017-07/msg00348.html
(until Peter backports it to gcc 7, 6 as approved).
This way gcc7 does not use an IFUNC at all and instead uses the builtin which
reads from the TCB data that has the expanded AT_HWCAP/AT_PLATFORM data.
That should be sufficient to fix your problem. No glibc changes required.
Peter commented that when we returned from Paris on the 19th he would checkin
the fixes to gcc7/6, so if he does that today then all you need to do is
re-sync gcc after that, and everything should work.
Does that answer your question?

--- Comment #14 from Pander <pander at users dot sourceforge.net> ---
Unfortunately, mixing on LC level doesn't do the trick. I gave a presentation
at NLUUG in 2016 in a room full of experienced sysadmin professionals
addressing all issues why not to include this. The locale was received with
great enthusiasm as it solves a series of problems that cannot be fixed in
another way. If you can find the time I could talk you through my presentation
personally.

PLT avoidance for __stack_chk_fail [BZ #7065]
Add a hidden __stack_chk_fail_local alias to libc.so,
and make sure that on targets which use __stack_chk_fail,
this does not introduce a local PLT reference into libc.so.
which unconditionally added
strong_alias (__stack_chk_fail, __stack_chk_fail_local)
defines __stack_chk_fail_local as an alias of __stack_chk_fail in libc.a.
There is no need to add stack_chk_fail_local.o to libc.a. We only need
to add stack_chk_fail_local.oS to libc_nonshared.a.
Tested on x86-64:

--- Comment #18 from Carlos O'Donell <carlos at redhat dot com> ---
(In reply to Andreas Schwab from comment #17)
> Why didn't the commit mention all these complications?
I can't answer for Tulio.
In my own past experience it was simply a problem of expectations. When I've
written commit messages it was with my current understanding of the patch, and
sometimes that produces terse commits that don't contain enough information to
help downstream distribution maintainers or don't explain enough of the
solution's constraints.
Hopefully this verbose writeup here in the bug will help other distribution
maintainers get past the build issues.
I empathize with your pain though, we had to go through the rebuild loop in
Fedora 27 for our mass rebuild.
What else can I do to help?

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

Bug ID: 21793
Summary: glibc does not update the pid/tid cache after clone()
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: thomasanderson at google dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
After commit [1], glibc no longer updates the TID cache after clone().
However, pthread still uses it, in eg. [2]. This is causing bug [3] in
Chromium where after a clone(), pthread_mutex_lock() erroneously says that the
lock is already owned by the calling thread when it is not. As a workaround,
doing an otherwise pointless fork() after the clone() forces glibc to update
the TID cache which fixes the issue.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
There are some discussion about this change on systemd-devel maillist regarding
another interface assumption that GLIBC does not really guarantee [1]. And the
problem, as Florian described there, is GLIBC can not really intercept anymore
all the ways the PID/TID of the process can change. And these caching also
have cause some issue in the past on GLIBC (some information at [2] [3] [4]).
And the problem IMHO is we can not guarantee that all pthread interfaces would
work correctly after a clone call, specially now with the proliferation of
different clone flags. If you check the pthread_create, not only the tid cache
is updated, but also the joinid (which at glance seems that might be
problematic after clone), the cancel handling, the stack guard, etc. I am not
sure which kind of pthread_t internal fields would need to correctly sync along
with the right combination of clone flags to make pthread interface to work
correctly, but this is out of POSIX pthread scope definition and a can of worms
imho.
I think for this specific issue it would be possible to issue a direct syscall
to actually get the tid of the thread and avoid using the cached, but this
would pessimize performance for a *very* speicifc case. I would like to hear
more community input if it would be a reasonable approach.

Once you call clone() you own the created thread, and you cannot use any POSIX
Thread functions provided by the libc you left behind when you cloned a new
thread manually. If you are using clone() as a convenience function for
unshare() then you should use unshare().
Take care that calling clone() yourself has implications on all the thread
APIs, from thread local storage, to cancellation, to joining, to exiting
threads, etc. You really really have to be ready to take over all aspects of
the new thread using your own threading runtime. The point of clone() is to
implement threading libraries, like those provided by glibc.
I'm all ears when it comes to hearing about what problems you use clone() to
solve and finding a better solution for you.

https://sc.wikipedia.org/wiki/Santandria says:
“Santandrìa (o Donniasantu) est su de ùndighi mese de su calendà riu
gregorianu.â€
Is “Onniasantu†in your patch really the correct spelling or should it be
“Donniasantuâ€
as in Wiktionary?
Wiktionary has at the bottom of the same page:
Meses de su calendà riu gregorianu
ghennà rgiu | freà rgiu | martzu | abrile | maju | là mpadas | trìulas/argiolas |
austu | cabudanni | santugaine/ladà mine | santandria/onniasantu |
nadale/meseidas
So here I see the spelling “onniasantuâ€. Maybe both “donniasantu†and
“onniasantu†is correct ...
Maybe the month names should start with lowercase?
Unless month names are always written with the first letter in uppercase in
Sardinian, I think
the month names should be stored in lowercase in the glibc locale. That is also
how CLDR does it.

Could you also add "yesstr" and "nostr" to your locale?

--- Comment #1 from Akhilesh Kumar <akhilesh.k at samsung dot com> ---
For Some countries Identifiers (979/978) are used with prefix (Two to Four) .
While playing with locals I found for Most of the Locals Identifiers are not
used also if country has more than one prefix only single prefix is added

(For reply using bugzilla because Unable to reply due to my locale system
issue)
I read think before, But i believe locale has lot of junk data/ Missing field
……
So I decided to take the latest field which are commonly used
Finally I referred below link….
https://en.wikipedia.org/wiki/List_of_ISBN_identifier_groups
> says:
>
> WP> Italy: The privately held company EDISER srl, owned by Associazione
> WP> Italiana Editori (Italian Publishers Association) is responsible for

> WP> publishing companies, starting at €49 for a ten-codes block[22] while a
> WP> new prefix 979-12 is dedicated to self-publishing authors, at a fixed
> WP> price of €25 for a single code.

> So I wonder whether 978-88 or 979-12 is correct for country_isbn.

There should be identical values of wcrtomb for first argument as NULL and
buffer
according to documentation. wcrtomb returns different values for first argument
as
NULL and buffer.

commit 7cae6abf283e3b886fd71972bcab425fab0a72b8
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Wed Jul 19 16:53:06 2017 -0700
tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

I agree that this behavior is non-obvious, but that's what the specification
says.

Bug ID: 21804
Summary: Double semicolon in thread-shared-types.h
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: krejzi at email dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Inside sysdeps/nptl/bits/thread-shared-types.h, there's a path where two
semicolons end up at the end of the line, resulting in compiler warnings such
as these:
/usr/include/bits/thread-shared-types.h:110: syntax error, unexpected ';' in '
;' at ';'
/usr/include/bits/thread-shared-types.h:112: syntax error, unexpected ';' in '
short __spins; short __elision;;' at ';'
/usr/include/bits/thread-shared-types.h:123: syntax error, unexpected ';' in '#
123 "/usr/include/bits/thread-shared-types.h" 3 4' at ';'
The issue is rather not important, but still annoying
When this #define:
https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/nptl/bits/thread-shared-types.h;h=1e45f2d8ce91a71da8f41c551e9618d6bb3c117f;hb=HEAD#l78
Gets expanded in:
https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/nptl/bits/thread-shared-types.h;h=1e45f2d8ce91a71da8f41c551e9618d6bb3c117f;hb=HEAD#l119
There ends up a path with two ;; at the end of union member define, resulting
in a warning. Solution: Remove second semicolon from the line first link points
to.

commit 77046c6153eb313e4f21a660fcb7e7060f71fd8a
Author: Rafal Luzynski <digitalfreak@lingonborough.com>
Date: Fri Jul 21 10:29:06 2017 +0200
localedata/locales/lg_UG: Fix some comments.
After the recent update of int_select the comment needed an update, too.
While at this, all comments in LC_TELEPHONE were moved above their
respective values because this looks better. Some minor typos fixed.
[BZ #21783]
* localedata/locales/lg_UG (LC_TELEPHONE): Move all comments
above the values, correct some of them.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Bug ID: 21812
Summary: getifaddrs() returns entries with ifa_name == NULL
Product: glibc
Version: 2.17
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: dalvarez at redhat dot com
Target Milestone: ---
When getifaddrs tries to retrieve the interface name for an address entry:
- If IFA_LABEL is present in the RTM_NEWADDR message, it grabs it from here [0]
- Else, it will pick it up from the interface [1]: it'll look up the
corresponding interface in the map and grab the name from it.
map_newlink() serves for two purposes: insert a new interface in the map and
lookup an interface from a previously (fully) populated map. In this case,
map_newlink iterates through the map and tries to find the interface whose id
matches the address interface.
The bug comes when this map is not fully populated, ie., it contains one or
more elements with map[x] == -1 and then, a lookup operation is transformed
into an insert operation and, hence, an "empty" interface is returned.
This will result in this assignment [2] to NULL:
ifas[ifa_index].ifa.ifa_name = ifas[idx].ifa.ifa_name;
I think that the assumption in map_newlink() that the interfaces map shouldn't
contain holes is not correct and it's explicitly advised in the code itself at
[3]:
"/* New Addresses are stored in the order we got them from
the kernel after the interfaces. Theoretically it is possible
that we have holes in the interface part of the list,
but we always have already the interface for this address. */
The only reason I can see for it to have holes is that kernel is returning more
than one RTM_NEWLINK messages for the same interface and, since we're
allocating memory for as many RTM_NEWLINK messages we received for our request,
then it means that some map entry will be -1 (value to which the map is
initialized).
This has been observed several times running the following versions of glibc
and kernel on a system with more than 500 interfaces which are often added and
removed so situation may be that an interface is added/remove in between
RTM_GETLINK and RTM_GETADDR in getifaddrs_internal()
glibc.x86_64 2.17-157.el7_3.1 installed
kernel.x86_64 3.10.0-514.6.1.el7

Compile tst-prelink.c without PIE [BZ #21815]
tst-prelink.c checks for conflict with GLOB_DAT relocation against stdio.
On i386, there is no GLOB_DAT relocation against stdio with PIE. We
should compile tst-prelink.c without PIE.
[BZ #21815]
* elf/Makefile (CFLAGS-tst-prelink.c): New.
(LDFLAGS-tst-prelink): Likewise.

The function maybe_enable_malloc_check, which is called by

This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.
H.J. Lu <hongjiu.lu@intel.com>
Adhemerval Zanella <adhemerval.zanella@linaro.org>
* elf/dl-tunables.c: Include not-errno.h header.
* include/unistd.h (__access_noerrno): Remove definition.
* sysdeps/unix/sysv/linux/access.c (__access_noerrno): Likewise.
* sysdeps/generic/not-errno.h: New file.
* sysdeps/unix/sysv/linux/not-errno.h: Likewise.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Compile tst-prelink.c without PIE [BZ #21815]
tst-prelink.c checks for conflict with GLOB_DAT relocation against stdio.
On i386, there is no GLOB_DAT relocation against stdio with PIE. We
should compile tst-prelink.c without PIE.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

commit 95a73392580761abc62fc9b1386d232cd55878e9
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Mon Jul 17 18:11:12 2017 -0300
tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.
H.J. Lu <hongjiu.lu@intel.com>
Adhemerval Zanella <adhemerval.zanella@linaro.org>
[BZ #21744]
* elf/dl-tunables.c: Include not-errno.h header.
* include/unistd.h (__access_noerrno): Remove definition.
* sysdeps/unix/sysv/linux/access.c (__access_noerrno): Likewise.

Bug ID: 21828
Summary: 2.26 changelog should mention user visible changes
with unicode 9.0
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: dx at dxzone dot com.ar
CC: libc-locales at sourceware dot org
Target Milestone: ---
Hi. The current version of the NEWS file for glibc 2.26 says:
>* Unicode 10.0.0 Support: Character encoding, character type info, and
> transliteration tables are all updated to Unicode 10.0.0, using
> generator scripts contributed by Mike FABIAN (Red Hat).
Previous versions also said "These updates cause user visible changes". 2.25
was unicode 8.0, and unicode 9.0 made one very visible change in the east asian
width[1][2] tables:
>Changed ED4 in Section 4 to state that characters with UTR #51 property
>Emoji_Presentation to be East Asian Wide
In other words, wcwidth(U+1F355) was 1 and is now 2, same thing for other
emoji.
Aside from being directly user visible (affecting UI rendering), this could
also result in glitches in remotely accessed terminal applications that depend
on this value matching between the server and the client's terminal. Same thing
that happened with the unicode 7.0 update, and not glibc's fault of course.
Usually it's nothing big, some terminal box drawing alignment issues, but
sometimes the desync results in partial redraws and leaving garbage on screen,
or replacing some characters with others. I've been meaning to figure out a way
to make it less ugly in that last instance, but it doesn't seem like it will
happen before glibc 2.26 is out.
So yeah, mentioning that it's a user visible change would be helpful.
Thanks.

Compile tst-prelink.c without PIE [BZ #21815]
tst-prelink.c checks for conflict with GLOB_DAT relocation against stdio.
On i386, there is no GLOB_DAT relocation against stdio with PIE. We
should compile tst-prelink.c without PIE.

Compile tst-prelink.c without PIE [BZ #21815]
tst-prelink.c checks for conflict with GLOB_DAT relocation against stdio.
On i386, there is no GLOB_DAT relocation against stdio with PIE. We
should compile tst-prelink.c without PIE.

Tons of codepoints are effected, even in BMP.
Bugzillas of terminal emulators and some other projects (e.g. powerline and
other zsh themes) as well as stackexchange sites are full of reports about such
user facing problems. You'll find at least 2 or 3 bugreports for
vte/gnome-terminal and further links from there.
(Browsing/typing from mobile so sorry for not posting actual links.)

Assigning to Mike to decide how he wants to adjust the NEWS wording and if we
need an entry in the packaging changes
(https://sourceware.org/glibc/wiki/Release/2.26#Packaging_Changes), which it
sounds like we do to warn developers.

--- Comment #5 from Torvald Riegel <triegel at redhat dot com> ---
Thanks for the bug report and the analysis. This bug was probably introduced
by me when fixing another robust mutex bug in
65810f0ef05e8c9e333f17a44e77808b163ca298; I believe this happened when changing
C11 atomics back to old-style atomics (which don't update the expected value
when they fail, whereas C11 CAS does).
I think there is a simpler fix, but I haven't tested this one yet:
--- a/nptl/pthread_mutex_lock.c
+++ b/nptl/pthread_mutex_lock.c
@@ -197,11 +197,14 @@ __pthread_mutex_lock_full (pthread_mutex_t *mutex)
{
/* Try to acquire the lock through a CAS from 0 (not acquired) to
our TID | assume_other_futex_waiters. */
- if (__glibc_likely ((oldval == 0)
- && (atomic_compare_and_exchange_bool_acq
- (&mutex->__data.__lock,
- id | assume_other_futex_waiters, 0) == 0)))
- break;
+ if (__glibc_likely (oldval == 0))
+ {
+ oldval
+ = atomic_compare_and_exchange_val_acq (&mutex->__data.__lock,
+ id | assume_other_futex_waiters, 0);
+ if (__glibc_likely (oldval == 0))
+ break;
+ }
if ((oldval & FUTEX_OWNER_DIED) != 0)
{
(and similar for timed locks).
This updates oldval, so further branches don't run with oldval==0.
Carlos, this is likely a regression. Is this still eligible for this release?
If so, I'd try to build a testsuite-ready test case based on the one posted
here, and post upstream tomorrow.

DJ noted that this was treated by the kernel as a regression and fixed in 2016:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=735f2770a770156100f534646158cb58cb8b2939
Thanks to the SUSE folks for making that happen.
The patch looks eminently backportable, so there is no reason to consider a
workaround on the glibc side (disregard what I said earlier).

Yes, and this does indeed effect the rendering a lot when pango is used, see:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
Fixes in pango are required to make emoji sequences render correctly again
which were broken because of the wcwidth changes.
> Aside from being directly user visible (affecting UI rendering), this could

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

This causes some application stability, but cannot be triggered deliberately to

--- Comment #3 from Florian Weimer <fweimer at redhat dot com> ---
(In reply to Carlos O'Donell from comment #2)
> Once you call clone() you own the created thread, and you cannot use any
> POSIX Thread functions provided by the libc you left behind when you cloned

That is very misleading. If you call clone to create a new *thread*, you
cannot use any glibc function at all, whether POSIX threads or not. *Nothing*
will work on the new thread, not even async-signal-safe functions. A lot of
things worked by accident, most of the time, including malloc, but with the
thread cache in 2.26, malloc will no longer be reliable, for instance.
We still need a correct TID if the clone call created a new process, though.
There is really no way around that. This will be tricky due to vfork.

I don't see an easy way to do it. Probably if you keep adding/removing
interfaces continuously, the odds that this happens increase plus if you do
this you would make getifaddrs() to retry over and over so it won't never
return to the caller.

Should we considere this NOTABUG/WONTFIX or add back tid update on clone?
Chrome developers seemed to not agree with us that glibc function are not
reliable after a clone call since they are now updating the tid cache by
themselves [1] (still a fragile fix imho).
I still would prefer to document clone and glibc interaction limitation rather
than provide incomplete and possible problematic solutions.

That's clearly a bogus change and will break once we change the TCB layout.

Right, that seems worthwhile. We could perhaps push the responsibility to
request a TID cache update to the caller, rather than trying to parse the flags
argument. That is, provide a different interface for a vfork-style clone which
would not update the cache (because it is shared with the parent).

Should it? We have 'fork' exactly for this case which setup us all the required
internal field for correct glibc usage. I give you that with current clone
flags this is a limited API.

I am not very found of providing a limited clone interface mainly because
interaction with glibc internals could have subtle bugs. Some I can think of:
1. It will need to pass CLONE_CHILD_SETTID and CLONE_CHILD_CLEARTID along with
TCB tid field. What happens if caller uses any of these flags along with a
different tid cached field? Would it just copy the tid value to argument passed
pointer? Can we have any synchronization issue with it?
2. What about fork handler, should it ignore it?
3. What about malloc internal locks so malloc is consistent on new process?
4. What about pthread robust list?
5. What if CLONE_THREAD is specified? Should we clear or ignore it? CLONE_VM
also poses some issues.
I still think that we already have a good interface to interact along with
clone and it the execv function family.

Indian scripts: More fixes after the recent import.
After the recent import of month names from CLDRv31 (bug 21217,
commit c853f14) an import of abbreviated month names is also needed
to make sure they match the full forms.
In case of kok_IN CLDR does not provide the abbreviated month names
explicitly but uses full month names in such cases so abmon section
has been copied from mon.

commit 2c030fc7a493140d70b44dd94f19e854f269ad61

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

Avoid .symver on common symbols [BZ #21666]
The .symver directive on common symbol just creates a new common symbol,
not an alias and the newer assembler with the bug fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21661
will issue an error. Before the fix, we got
$ readelf -sW libc.so | grep "loc[12s]"
5109: 00000000003a0608 8 OBJECT LOCAL DEFAULT 36 loc1
5188: 00000000003a0610 8 OBJECT LOCAL DEFAULT 36 loc2

7312: 00000000003a0600 8 OBJECT GLOBAL DEFAULT 36 loc2@GLIBC_2.2.5
in libc.so. The versioned loc1, loc2 and locs have the wrong addresses.
After the fix, we got
$ readelf -sW libc.so | grep "loc[12s]"
6570: 000000000039e3b8 8 OBJECT GLOBAL DEFAULT 34 locs@GLIBC_2.2.5

commit fd5fade3054e4e5356154ea24e65d7ed816f5a1d
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Wed Jul 26 10:08:46 2017 -0700
Avoid .symver on common symbols [BZ #21666]
The .symver directive on common symbol just creates a new common symbol,
not an alias and the newer assembler with the bug fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21661
will issue an error. Before the fix, we got
$ readelf -sW libc.so | grep "loc[12s]"
5109: 00000000003a0608 8 OBJECT LOCAL DEFAULT 36 loc1
5188: 00000000003a0610 8 OBJECT LOCAL DEFAULT 36 loc2
5455: 00000000003a0618 8 OBJECT LOCAL DEFAULT 36 locs

7312: 00000000003a0600 8 OBJECT GLOBAL DEFAULT 36 loc2@GLIBC_2.2.5
in libc.so. The versioned loc1, loc2 and locs have the wrong addresses.
After the fix, we got
$ readelf -sW libc.so | grep "loc[12s]"
6570: 000000000039e3b8 8 OBJECT GLOBAL DEFAULT 34 locs@GLIBC_2.2.5

7307: 000000000039e3c0 8 OBJECT GLOBAL DEFAULT 34 loc2@GLIBC_2.2.5
[BZ #21666]
* misc/regexp.c (loc1): Add __attribute__ ((nocommon));
(loc2): Likewise.
(locs): Likewise.
(cherry picked from commit 388b4f1a02f3a801965028bbfcd48d905638b797)

posix: Fix glob with GLOB_NOCHECK returning modified patterns (BZ#10246)
Acconding to POSIX glob with GLOB_NOCHECK should return a list consisting
of only of the input pattern in case of no match. However GLIBC does not
honor in case of '//<something'. This is due internally this is handled
and special case and prefix_array (responsable to prepend the directory
name) does not know if the input already contains a slash or not since
either '/<something>' or '//<something>' will be handle in same way.
This patch fix it by using a empty directory name for the latter (since
prefix_array already adds a slash as default for each entry).
Checked on x86_64-linux-gnu.

* posix/glob.c (glob): Handle pattern that do not match and
start with '/' correctly.

posix: Remove glob GET_LOGIN_NAME_MAX usage
Current glob implementation allows non limited user name for home
directory construction on GLOB_TILDE case. To accomplish it glob
either construct a name on stack if size are small enough (based
on current alloca_used) value in heap otherwise.
There is no actual login to resize the buffer in case of the resizing
the buffer in case of ERANGE, so a static buffer using glibc default
LOGIN_NAME_MAX is suffice.

posix: Use char_array for internal glob dirname
This is the first patch of the set to remove alloca usage on glob
implementation. Internal path to search for file might expand to a
non static directory derived from pattern for some difference cases
(GLOB_NOESCAPE, GNU GLOB_TILDE) and to allow a non-static dirname
path glob uses a lot of boilerplate code to manage the buffer (which
is either allocated using alloca or malloc depending both to size
requested and the total alloca_used).
The patch changes to use the char_array struct with the default size
(256 bytes). It simplifies all the allocation code by using char_array
one and every internal buffer access is done using char_array provided
functions. No functional changes are expected.
Checked on x86_64-linux-gnu.

posix: Consolidate glob implementation
This patch consolidates the glob implementation. The main changes are:
* Remove specific defines required for multiple compilation in same
unit (GLOB_ONLY_P, NO_GLOB_PATTERN_P and GLOB_COMPAT_BUILD). To allow
using the same code to build compat version on Linux, extra units are
used instead (oldglob.c).
* Both globfree and GNU extension glob_pattern_p are now on their files.
This simplifies the creation of compat symbol when required.
* Also similar to glob/glob64, a new globfree64 is file is added with an
empty implementatio as default.
* On Linux all implementation now uses a default one with the exception
of alpha (which requires a specific versioning) and s390-32 (which
different than other 32 bits with support for v2.1 symbol does not
add a compat symbol).
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different
architectures (and used on compat glob symbol).
Checked on x86_64-linux-gnu and i686-linux-gnu.
* posix/Makefile (routines): Add globfree, globfree64, and
glob_pattern_p.

NO_GLOB_PATTERN_P define usage.

posix: Allow glob to match dangling symlinks [BZ #866]
This patch makes glob match dangling symlinks. Compared to other glob
implementation (*BSD, bash, musl, and other shells as well), GLIBC seems
the be the only one that does not match dangling symlinks. As for
comment #5 in BZ #866, POSIX does not have any strict specification for
dangling symlinks match and it is reasonable that trying to glob everything
in a path should return all types of files (such as for a 'rm *'). Also,
comment #7 shows even more example where GLIBC current behavior is
unexepected.
I avoided adding another GNU specific flag to set this behavior and
instead make it the default. Although this change the semanthic from
previous implementation, I think adding another compat symbol to be
really unecessary as from aforementioned reasons (current behavior not
defined in any standard, general idea of different implementation is
to list dangling symbols).
Checked on x86_64-linux-gnu.
* posix/Makefile (tests): Add tst-glob_symlinks and remove tst-glob3.
* posix/bug-glob1.c: Remove file.
* posix/glob.c (glob): Match dangling symlinks.

posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version
1540f34. The main differences to gnulib code:
1. Commit 44c637c (Properly initialize glob structure with
GLOB_BRACE|GLOB_DOOFFS) which fixes BZ# 20707.
2. No inclusion of flexmember.h header and its usage on glob.
The code is meant to be rewritten and header is unrequired in
next patch in this set.
3. An additional define (GLOB_COMPAT_BUILD) to avoid building
size_and_wrapv and gblo_use_alloca twice on some configurations
(i368 compat code) due multiple inclusion.
The main changes are:
- Header organization mostly due gnulib requirements. It leads
to some simplification and less conditional includes.
- Use of glob_use_alloca with wraps up __libc_use_alloca with
saturated math for the total size calculation.
- Simplify some size allocation overflow calculation.
- Some fixed on non supported glibc systems.
- Some comments adjustments.
The changes does not alter current glob internal semantic. I also
added a missing globfree on posix/globtest.c (it helps silence
some valgrind or other memory profilers).
[BZ #1062]
* posix/glob.c: Sync with gnulib.
* posix/globtest.c (main): Add final globfree.
* sysdeps/unix/sysv/linux/i386/glob64.c (GLOB_COMPAT_BUILD):

malloc: Add specialized dynarray for C strings
This patch adds an specialized dynarray to manage C strings using the
dynarray internal implementation. It uses some private fields from
dynarray and thus it provided specific files to access and manage
the internal string buffer.
For instance:
struct char_array str;
// str == "testing"
char_array_init_str (&str, "testing");
// c == 's'
char c = char_array_pos (&str, 2);
// str = "testing2"

The provided function are not extensive and meant mainly to be use in
subsequent glob implementation cleanup. For internal object consistency
only the function provided by char_array.c should be used, including
internal object manipulation.
To check for possible overflows in internal size manipulation a new
function, check_add_wrapv_size_t, is added on malloc-internal. It
basically
return whether the addition of two size_t overflows.

posix: Fix glob with GLOB_NOCHECK returning modified patterns (BZ#10246)
Acconding to POSIX glob with GLOB_NOCHECK should return a list consisting
of only of the input pattern in case of no match. However GLIBC does not
honor in case of '//<something'. This is due internally this is handled
and special case and prefix_array (responsable to prepend the directory
name) does not know if the input already contains a slash or not since
either '/<something>' or '//<something>' will be handle in same way.
This patch fix it by using a empty directory name for the latter (since
prefix_array already adds a slash as default for each entry).
Checked on x86_64-linux-gnu.

posix: Use char_array for internal glob dirname
This is the first patch of the set to remove alloca usage on glob
implementation. Internal path to search for file might expand to a
non static directory derived from pattern for some difference cases
(GLOB_NOESCAPE, GNU GLOB_TILDE) and to allow a non-static dirname
path glob uses a lot of boilerplate code to manage the buffer (which
is either allocated using alloca or malloc depending both to size
requested and the total alloca_used).
The patch changes to use the char_array struct with the default size
(256 bytes). It simplifies all the allocation code by using char_array
one and every internal buffer access is done using char_array provided
functions. No functional changes are expected.

posix: Consolidate glob implementation
This patch consolidates the glob implementation. The main changes are:
* Remove specific defines required for multiple compilation in same
unit (GLOB_ONLY_P, NO_GLOB_PATTERN_P and GLOB_COMPAT_BUILD). To allow
using the same code to build compat version on Linux, extra units are
used instead (oldglob.c).
* Both globfree and GNU extension glob_pattern_p are now on their files.
This simplifies the creation of compat symbol when required.
* Also similar to glob/glob64, a new globfree64 is file is added with an
empty implementatio as default.
* On Linux all implementation now uses a default one with the exception
of alpha (which requires a specific versioning) and s390-32 (which
different than other 32 bits with support for v2.1 symbol does not
add a compat symbol).
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different
architectures (and used on compat glob symbol).
Checked on x86_64-linux-gnu and i686-linux-gnu.
* posix/Makefile (routines): Add globfree, globfree64, and
glob_pattern_p.

posix: Allow glob to match dangling symlinks [BZ #866]
This patch makes glob match dangling symlinks. Compared to other glob
implementation (*BSD, bash, musl, and other shells as well), GLIBC seems
the be the only one that does not match dangling symlinks. As for
comment #5 in BZ #866, POSIX does not have any strict specification for
dangling symlinks match and it is reasonable that trying to glob everything
in a path should return all types of files (such as for a 'rm *'). Also,
comment #7 shows even more example where GLIBC current behavior is
unexepected.
I avoided adding another GNU specific flag to set this behavior and
instead make it the default. Although this change the semanthic from
previous implementation, I think adding another compat symbol to be
really unecessary as from aforementioned reasons (current behavior not
defined in any standard, general idea of different implementation is
to list dangling symbols).
Checked on x86_64-linux-gnu.
* posix/Makefile (tests): Add tst-glob_symlinks and remove tst-glob3.

posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version
1540f34. The main differences to gnulib code:
1. Commit 44c637c (Properly initialize glob structure with
GLOB_BRACE|GLOB_DOOFFS) which fixes BZ# 20707.
2. No inclusion of flexmember.h header and its usage on glob.
The code is meant to be rewritten and header is unrequired in
next patch in this set.
3. An additional define (GLOB_COMPAT_BUILD) to avoid building
size_and_wrapv and gblo_use_alloca twice on some configurations
(i368 compat code) due multiple inclusion.
The main changes are:
- Header organization mostly due gnulib requirements. It leads
to some simplification and less conditional includes.
- Use of glob_use_alloca with wraps up __libc_use_alloca with
saturated math for the total size calculation.
- Simplify some size allocation overflow calculation.
- Some fixed on non supported glibc systems.
- Some comments adjustments.
The changes does not alter current glob internal semantic. I also
added a missing globfree on posix/globtest.c (it helps silence
some valgrind or other memory profilers).
[BZ #1062]
* posix/glob.c: Sync with gnulib.
* posix/globtest.c (main): Add final globfree.
* sysdeps/unix/sysv/linux/i386/glob64.c (GLOB_COMPAT_BUILD):

malloc: Add specialized dynarray for C strings
This patch adds an specialized dynarray to manage C strings using the
dynarray internal implementation. It uses some private fields from
dynarray and thus it provided specific files to access and manage
the internal string buffer.
For instance:
struct char_array str;
// str == "testing"
char_array_init_str (&str, "testing");
// c == 's'
char c = char_array_pos (&str, 2);
// str = "testing2"
char_array_set_str (&str, "testing2");
// str = "testi"
char_array_erase (&str, 5);
// str = "123testi"
char_array_prepend_str (&str, "123");
// len = 8
size_t len = char_array_length (&str);
// str = "123testi456"
char_array_append_str (&str, "456");
// str = "123testi789"
char_array_replace_str_pos (&str, 7, "789", 3);
The provided function are not extensive and meant mainly to be use in
subsequent glob implementation cleanup. For internal object consistency
only the function provided by char_array.c should be used, including
internal object manipulation.
To check for possible overflows in internal size manipulation a new
function, check_add_wrapv_size_t, is added on malloc-internal. It
basically
return whether the addition of two size_t overflows.
Checked on x86_64-linux-gnu.
* malloc/Makefile (test-internal): Add tst-char_array.
(routines): Add dynarray_overflow_failure and char_array-impl.
* malloc/Versions [GLIBC_PRIVATE] (libc): Add
__libc_dynarray_overflow_failure, __char_array_set_str_size,
__char_array_erase, __char_array_prepend_str_size, and
__char_array_replace_str_pos.

posix: Fix glob with GLOB_NOCHECK returning modified patterns (BZ#10246)
Acconding to POSIX glob with GLOB_NOCHECK should return a list consisting
of only of the input pattern in case of no match. However GLIBC does not
honor in case of '//<something'. This is due internally this is handled
and special case and prefix_array (responsable to prepend the directory
name) does not know if the input already contains a slash or not since
either '/<something>' or '//<something>' will be handle in same way.
This patch fix it by using a empty directory name for the latter (since
prefix_array already adds a slash as default for each entry).
Checked on x86_64-linux-gnu.

posix: Use char_array for internal glob dirname
This is the first patch of the set to remove alloca usage on glob
implementation. Internal path to search for file might expand to a
non static directory derived from pattern for some difference cases
(GLOB_NOESCAPE, GNU GLOB_TILDE) and to allow a non-static dirname
path glob uses a lot of boilerplate code to manage the buffer (which
is either allocated using alloca or malloc depending both to size
requested and the total alloca_used).
The patch changes to use the char_array struct with the default size
(256 bytes). It simplifies all the allocation code by using char_array
one and every internal buffer access is done using char_array provided
functions. No functional changes are expected.

posix: Consolidate glob implementation
This patch consolidates the glob implementation. The main changes are:
* Remove specific defines required for multiple compilation in same
unit (GLOB_ONLY_P, NO_GLOB_PATTERN_P and GLOB_COMPAT_BUILD). To allow
using the same code to build compat version on Linux, extra units are
used instead (oldglob.c).
* Both globfree and GNU extension glob_pattern_p are now on their files.
This simplifies the creation of compat symbol when required.
* Also similar to glob/glob64, a new globfree64 is file is added with an
empty implementatio as default.
* On Linux all implementation now uses a default one with the exception
of alpha (which requires a specific versioning) and s390-32 (which
different than other 32 bits with support for v2.1 symbol does not
add a compat symbol).
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different
architectures (and used on compat glob symbol).
Checked on x86_64-linux-gnu and i686-linux-gnu.
* posix/Makefile (routines): Add globfree, globfree64, and
glob_pattern_p.

posix: Allow glob to match dangling symlinks [BZ #866]
This patch makes glob match dangling symlinks. Compared to other glob
implementation (*BSD, bash, musl, and other shells as well), GLIBC seems
the be the only one that does not match dangling symlinks. As for
comment #5 in BZ #866, POSIX does not have any strict specification for
dangling symlinks match and it is reasonable that trying to glob everything
in a path should return all types of files (such as for a 'rm *'). Also,
comment #7 shows even more example where GLIBC current behavior is
unexepected.
I avoided adding another GNU specific flag to set this behavior and
instead make it the default. Although this change the semanthic from
previous implementation, I think adding another compat symbol to be
really unecessary as from aforementioned reasons (current behavior not
defined in any standard, general idea of different implementation is
to list dangling symbols).

1540f34. The main differences to gnulib code:
1. Commit 44c637c (Properly initialize glob structure with
GLOB_BRACE|GLOB_DOOFFS) which fixes BZ# 20707.
2. No inclusion of flexmember.h header and its usage on glob.
The code is meant to be rewritten and header is unrequired in
next patch in this set.
3. An additional define (GLOB_COMPAT_BUILD) to avoid building
size_and_wrapv and gblo_use_alloca twice on some configurations
(i368 compat code) due multiple inclusion.
The main changes are:
- Header organization mostly due gnulib requirements. It leads
to some simplification and less conditional includes.
- Use of glob_use_alloca with wraps up __libc_use_alloca with
saturated math for the total size calculation.
- Simplify some size allocation overflow calculation.
- Some fixed on non supported glibc systems.
- Some comments adjustments.
The changes does not alter current glob internal semantic. I also
added a missing globfree on posix/globtest.c (it helps silence
some valgrind or other memory profilers).
[BZ #1062]
* posix/glob.c: Sync with gnulib.
* posix/globtest.c (main): Add final globfree.
* sysdeps/unix/sysv/linux/i386/glob64.c (GLOB_COMPAT_BUILD):
Define.

malloc: Add specialized dynarray for C strings
This patch adds an specialized dynarray to manage C strings using the
dynarray internal implementation. It uses some private fields from
dynarray and thus it provided specific files to access and manage
the internal string buffer.
For instance:
struct char_array str;
// str == "testing"
char_array_init_str (&str, "testing");
// c == 's'
char c = char_array_pos (&str, 2);
// str = "testing2"
char_array_set_str (&str, "testing2");
// str = "testi"
char_array_erase (&str, 5);
// str = "123testi"
char_array_prepend_str (&str, "123");
// len = 8
size_t len = char_array_length (&str);
// str = "123testi456"
char_array_append_str (&str, "456");
// str = "123testi789"
char_array_replace_str_pos (&str, 7, "789", 3);
The provided function are not extensive and meant mainly to be use in
subsequent glob implementation cleanup. For internal object consistency
only the function provided by char_array.c should be used, including
internal object manipulation.
To check for possible overflows in internal size manipulation a new
function, check_add_wrapv_size_t, is added on malloc-internal. It
basically
return whether the addition of two size_t overflows.
Checked on x86_64-linux-gnu.
* malloc/Makefile (test-internal): Add tst-char_array.
(routines): Add dynarray_overflow_failure and char_array-impl.
* malloc/Versions [GLIBC_PRIVATE] (libc): Add
__libc_dynarray_overflow_failure, __char_array_set_str_size,
__char_array_erase, __char_array_prepend_str_size, and
__char_array_replace_str_pos.
* malloc/char_array-impl.c: New file.
* malloc/char_array-skeleton.c: Likewise.
* malloc/char_array.h: Likewise.
* malloc/tst-char-array.c: Likewise.
* malloc/dynarray_overflow_failure.c: Likewise.

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc
i386 _dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding. However,
internal_function, which should be used only with hidden function, is
defined as
# define internal_function __attribute__ ((regparm (3), stdcall))
and used with private function calls between different shared objects of
glibc. We introduce private_function for such purpose:
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used by _dl_runtime_resolve as scratch register.

posix: Fix glob with GLOB_NOCHECK returning modified patterns (BZ#10246)
Acconding to POSIX glob with GLOB_NOCHECK should return a list consisting
of only of the input pattern in case of no match. However GLIBC does not
honor in case of '//<something'. This is due internally this is handled
and special case and prefix_array (responsable to prepend the directory
name) does not know if the input already contains a slash or not since
either '/<something>' or '//<something>' will be handle in same way.
This patch fix it by using a empty directory name for the latter (since
prefix_array already adds a slash as default for each entry).
Checked on x86_64-linux-gnu.

* posix/glob.c (glob): Handle pattern that do not match and

posix: Remove glob GET_LOGIN_NAME_MAX usage
Current glob implementation allows non limited user name for home
directory construction on GLOB_TILDE case. To accomplish it glob
either construct a name on stack if size are small enough (based
on current alloca_used) value in heap otherwise.
There is no actual login to resize the buffer in case of the resizing
the buffer in case of ERANGE, so a static buffer using glibc default
LOGIN_NAME_MAX is suffice.

posix: Use char_array for internal glob dirname
This is the first patch of the set to remove alloca usage on glob
implementation. Internal path to search for file might expand to a
non static directory derived from pattern for some difference cases
(GLOB_NOESCAPE, GNU GLOB_TILDE) and to allow a non-static dirname
path glob uses a lot of boilerplate code to manage the buffer (which
is either allocated using alloca or malloc depending both to size
requested and the total alloca_used).
The patch changes to use the char_array struct with the default size
(256 bytes). It simplifies all the allocation code by using char_array
one and every internal buffer access is done using char_array provided
functions. No functional changes are expected.
Checked on x86_64-linux-gnu.

posix: Consolidate glob implementation
This patch consolidates the glob implementation. The main changes are:
* Remove specific defines required for multiple compilation in same
unit (GLOB_ONLY_P, NO_GLOB_PATTERN_P and GLOB_COMPAT_BUILD). To allow
using the same code to build compat version on Linux, extra units are
used instead (oldglob.c).
* Both globfree and GNU extension glob_pattern_p are now on their files.
This simplifies the creation of compat symbol when required.
* Also similar to glob/glob64, a new globfree64 is file is added with an
empty implementatio as default.
* On Linux all implementation now uses a default one with the exception
of alpha (which requires a specific versioning) and s390-32 (which
different than other 32 bits with support for v2.1 symbol does not
add a compat symbol).
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different
architectures (and used on compat glob symbol).
Checked on x86_64-linux-gnu and i686-linux-gnu.
* posix/Makefile (routines): Add globfree, globfree64, and
glob_pattern_p.

posix: Allow glob to match dangling symlinks [BZ #866]
This patch makes glob match dangling symlinks. Compared to other glob
implementation (*BSD, bash, musl, and other shells as well), GLIBC seems
the be the only one that does not match dangling symlinks. As for
comment #5 in BZ #866, POSIX does not have any strict specification for
dangling symlinks match and it is reasonable that trying to glob everything
in a path should return all types of files (such as for a 'rm *'). Also,
comment #7 shows even more example where GLIBC current behavior is
unexepected.
I avoided adding another GNU specific flag to set this behavior and
instead make it the default. Although this change the semanthic from
previous implementation, I think adding another compat symbol to be
really unecessary as from aforementioned reasons (current behavior not
defined in any standard, general idea of different implementation is
to list dangling symbols).

* posix/Makefile (tests): Add tst-glob_symlinks and remove tst-glob3.
* posix/bug-glob1.c: Remove file.

posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version
1540f34. The main differences to gnulib code:
1. Commit 44c637c (Properly initialize glob structure with
GLOB_BRACE|GLOB_DOOFFS) which fixes BZ# 20707.
2. No inclusion of flexmember.h header and its usage on glob.
The code is meant to be rewritten and header is unrequired in
next patch in this set.
3. An additional define (GLOB_COMPAT_BUILD) to avoid building
size_and_wrapv and gblo_use_alloca twice on some configurations
(i368 compat code) due multiple inclusion.
The main changes are:
- Header organization mostly due gnulib requirements. It leads
to some simplification and less conditional includes.
- Use of glob_use_alloca with wraps up __libc_use_alloca with
saturated math for the total size calculation.
- Simplify some size allocation overflow calculation.
- Some fixed on non supported glibc systems.
- Some comments adjustments.
The changes does not alter current glob internal semantic. I also
added a missing globfree on posix/globtest.c (it helps silence
some valgrind or other memory profilers).
[BZ #1062]
* posix/glob.c: Sync with gnulib.
* posix/globtest.c (main): Add final globfree.
* sysdeps/unix/sysv/linux/i386/glob64.c (GLOB_COMPAT_BUILD):

malloc: Add specialized dynarray for C strings
This patch adds an specialized dynarray to manage C strings using the
dynarray internal implementation. It uses some private fields from
dynarray and thus it provided specific files to access and manage
the internal string buffer.
For instance:
struct char_array str;
// str == "testing"
char_array_init_str (&str, "testing");
// c == 's'
char c = char_array_pos (&str, 2);
// str = "testing2"
char_array_set_str (&str, "testing2");
// str = "testi"
char_array_erase (&str, 5);
// str = "123testi"
char_array_prepend_str (&str, "123");
// len = 8
size_t len = char_array_length (&str);
// str = "123testi456"
char_array_append_str (&str, "456");
// str = "123testi789"
char_array_replace_str_pos (&str, 7, "789", 3);
The provided function are not extensive and meant mainly to be use in
subsequent glob implementation cleanup. For internal object consistency
only the function provided by char_array.c should be used, including
internal object manipulation.
To check for possible overflows in internal size manipulation a new
function, check_add_wrapv_size_t, is added on malloc-internal. It
basically
return whether the addition of two size_t overflows.
Checked on x86_64-linux-gnu.
* malloc/Makefile (test-internal): Add tst-char_array.
(routines): Add dynarray_overflow_failure and char_array-impl.
* malloc/Versions [GLIBC_PRIVATE] (libc): Add
__libc_dynarray_overflow_failure, __char_array_set_str_size,
__char_array_erase, __char_array_prepend_str_size, and
__char_array_replace_str_pos.

POC to trigger null pointer dereference (radare2)
While fuzzing radare2 (https://github.com/radare/radare2) I've triggered a null
pointer dereference in strlen().
libc version: stable release version 2.25
OS: Manjaro 17.0.2 x64
To reproduce: r2 -A libc_strlen
ASAN:

Target Milestone: ---
I don't know if this is a glibc bug or not. On ppc64le with recent binutils
2.29, applicaitons fail to start with errors like:
./bin/rustc: error while loading shared libraries:
./lib/libstd-c3a1748e15265da7.so: expected localentry:0
`pthread_condattr_destroy'
/usr/bin/cmake: error while loading shared libraries: /lib64/libcurl.so.4:
expected localentry:0 `pthread_mutex_destroy'
./dsimpletest: error while loading shared libraries:
../lib/libmumps_common-5.1.1.so: expected localentry:0 `pthread_cond_init'
The common theme seems to be that this only affects symbols which live both in
libpthread and libc.

strlen(3) and strdup(3) operate with strings specified by pointer arguments.
Null pointer specifies no valid string, passing it to strdup(3) or strlen(3)
invokes an undefined behaviour.

Hi Riegel,
Yes, I agree your fix is simpler and faster...I'll take this fix in our code,
after you applied it to trunk :)

You are absolutely right, I didn't mean to limit the scope to just the POSIX
thread functions, but was answering in the context of this issue and that made
my response misleading.
> We still need a correct TID if the clone call created a new process, though.

When you say 'we' do you mean just glibc internally? If so, then I agree. The
library needs a correct TID in order for it's own functions to work reliably,
the user doesn't need a TID and we don't provide gettid() nor document what a
TID is in respect to a PID or pthread_t.
I think what's under contention here is: Should clone() with the appropriate
flags to behave like fork(), or vfork(), actually be a supported API which
after calling still allows you to call back into the runtime?
Are you arguing that when clone() is used in a fork-like manner that it should
work just like fork. Why not just use fork() or vfork()?
I agree with Adhemerval that the use of clone() is bound to cause us no end of
problems, and that we should document that after a clone() call you can't call
any libc functions. You have effectively ended the ability to use any library
functions until you execve, much like the official story for vfork().
If anything we should be adding documentation to state which functions are, as
a GNU extension, supported and safe to call between vfork() and exec()/exit().
Which would be easier to explain and document those semantics.

I suggested to provide two wrappers, perhaps called clone_fork and clone_vfork.
clone_fork updates the TID cache in the child, clone_vfork does not, but
perhaps sets a flag that in child that the TID cache is invalid, which is later
reset in the parent.
We should move this discussion to libc-alpha.

2.29 is the first release supporting PPC64_OPT_LOCALENTRY, so it seem like this
is still buggy.

rwlock: Fix explicit hand-over (bug 21298)
Without this fix, the rwlock can fail to execute the explicit hand-over
in certain cases (e.g., empty critical sections that switch quickly between
read and write phases). This can then lead to errors in how
__wrphase_futex
is accessed, which in turn can lead to deadlocks.

--- Comment #3 from Alan Modra <amodra at gmail dot com> ---
It may be that the localentry:0 optimisation needs to be turned off by default
in ld. Which is a shame, because it gives a nice speedup for plt calls to many
small leaf functions.

The problem is this:

pthread_condattr_destroy.
694: 0000000000011f70 20 FUNC GLOBAL DEFAULT 11
pthread_condattr_destroy
libpthread.so.0 has a stub implementation of pthread_condattr_destroy which
consists of just
ld r3,0
blr
while libc.so.6 has the full implementation. Users link against libpthread.so
which means ld sees the stub symbol first before finding the real
implementation in libc.so. By the usual rules of duplicate symbol resolution
involving shared libraries, ld must take the first symbol as the definition.
The stub symbol of course doesn't need a toc pointer so the optimised
localentry:0 call is used. At runtime, ld.so apparently resolves
pthread_condattr_destroy to the libc version, which isn't localentry:0.
I'm not familiar with the reasons for glibc having two conflicting
implementations for pthread functions, but I believe the correct fix is to make
the libpthread.so stub symbols weak.

But this is the full implementation. The stub implementation is in libc.so.6.
I agree that it is bizarre that the stub implementation does more work than the
real implementation, but that's just an artifact of pthread_condattr_destroy.
The problem also happens with pthread_mutex_destroy, where there is actually
some code in libpthread.

How does this optimization work? Does the link editor detect that the
implementation in libpthread does not require the TOC pointer and then
activates the optimization? What happens if we change the implementation
later, so that it needs a TOC pointer?
I still think this optimization has a general issue with symbol interposition.

That seems wrong because the libpthread implementation is the real (full)
implementation.

That could be solved by versioning.

True.

OK, so I had it back to front. How is it that an executable or shared library
linked against libpthread.so.0 ends up not using the libpthread.so.0 symbols at
run time?

microblaze: Resolve non-relocatable branch in pt-vfork.S (BZ#21779)
The relative branch directly to __libc_vfork results in an relocation
that cannot be resolved. Specifically a R_MICROBLAZE_64_PCREL relocation
is created for this branch, however for MicroBlaze R_MICROBLAZE_64_PCREL
type relocations symbols are not resolved. Additionally due to the
branch being located in the .text section the instruction cannot be
rewritten as the section is not writable, and causes a segfault at
runtime when loading libpthread.
To resolve this issue, ensure the branch is done using PLT. This removes
the need to modify the instruction and trades the R_MICROBLAZE_64_PCREL
for a more common R_MICROBLAZE_JUMP via the PLT.
[BZ #21779]
* sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Branch using PLT.

Note that in that case I think it can be even exact compiler version and
optimization options that affect ABI, say with -O0 or -O1 the compiler doesn't
optimize some dead, but harder to be proven as dead, access to a global
variable, while -O2 or -O3 or whatever other option could optimize that away
and make the function not using r2 anymore.
So like that the localentry change is useful only for the development models
where any single change causes rebuild of all the binaries and shared libraries
and then nothing changes until following whole world rebuild.
What could work is a shared library providing a hint to the dynamic linker,
this function doesn't need or clobber r2, say in some .dynsym flags, and only
the dynamic linker then using that information as a hint whether to use a more
or less efficient PLT sequence when calling certain symbol. But it has to be
something only determined at runtime, there can't be anything decided at static
link time (because then some property that is not part of ABI is inlined into
binaries or shared libraries otherwise).

mutex: Fix robust mutex lock acquire (Bug 21778)
65810f0ef05e8c9e333f17a44e77808b163ca298 fixed a robust mutex bug but
introduced BZ 21778: if the CAS used to try to acquire a lock fails, the
expected value is not updated, which breaks other cases in the loce
acquisition loop. The fix is to simply update the expected value with
the value returned by the CAS, which ensures that behavior is as if the
first case with the CAS never happened (if the CAS fails).
This is a regression introduced in the last release.
Tested on x86_64, i686, ppc64, ppc64le, s390x, aarch64, armv7hl.

Bug ID: 21862
Summary: Incorrect character widths for Tamil script
Product: glibc
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: locale
Assignee: unassigned at sourceware dot org
Reporter: eual.jp at gmail dot com
Target Milestone: ---
Created attachment 10292
--> https://sourceware.org/bugzilla/attachment.cgi?id=10292&action=edit
A screenshot of program's output
wcswidth underestimates the number of columns required to display a string in
Tamil: it reports 35 columns, while in reality we need 39 (see the attached
screenshot). The code that produced it is:
#define _XOPEN_SOURCE
#include <wchar.h>
#include <locale.h>
int main()
{
const wchar_t * text = L"மாத சமà¯à®ªà®³à®®à¯ நனà¯à®•à¯Šà®Ÿà¯ˆ: அதிபர௠டிரமà¯à®ªà¯ அசதà¯à®¤à®²à¯";
setlocale(LC_ALL, "en_US.utf8");
wprintf(L" | . | . | . | . | .
|\n");
wprintf(L"String: %ls\n", text);
wprintf(L"Its length is %zi characters.\n", wcslen(text));
wprintf(L"It needs %i columns to be printed out.\n", wcswidth(text,
wcslen(text)));
return 0;
}
I followed the code up until the call to _NL_CURRENT (LC_CTYPE,
_NL_CTYPE_WIDTH), but I can't find the place where the table that _NL_CURRENT
returns is generated.
(This bug is the result of a bug filed against an application that I maintain:
https://github.com/akrennmair/newsbeuter/issues/584 )

x86-64: Use IFUNC memcpy and mempcpy in libc.a
Since apply_irel is called before memcpy and mempcpy are called, we
can use IFUNC memcpy and mempcpy in libc.a.
* sysdeps/x86_64/memmove.S (MEMCPY_SYMBOL): Don't check SHARED.
(MEMPCPY_SYMBOL): Likewise.
* sysdeps/x86_64/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Test memcpy and mempcpy in libc.a.
* sysdeps/x86_64/multiarch/memcpy-ssse3-back.S: Also include
in libc.a.
* sysdeps/x86_64/multiarch/memcpy-ssse3.S: Likewise.
* sysdeps/x86_64/multiarch/memmove-avx512-no-vzeroupper.S:
Likewise.
* sysdeps/x86_64/multiarch/memcpy.c: Also include in libc.a.
(__hidden_ver1): Don't use in libc.a.
* sysdeps/x86_64/multiarch/memmove-sse2-unaligned-erms.S
(__mempcpy): Don't create a weak alias in libc.a.
* sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S: Support
libc.a.
* sysdeps/x86_64/multiarch/mempcpy.c: Also include in libc.a.

Don't include _dl_resolve_conflicts in libc.a [BZ #21742]
Since _dl_resolve_conflicts is only used in elf/rtld.c, don't include
it in libc.a.
[BZ #21742]
* elf/dl-conflict.c (_dl_resolve_conflicts): Define only if
SHARED is defined.

i386: Define I386_USE_SYSENTER to 0 or 1 and check PIC
Define I386_USE_SYSENTER to 0 or 1 so that special versions of syscalls

Compile tst-prelink.c without PIE [BZ #21815]
tst-prelink.c checks for conflict with GLOB_DAT relocation against stdio.
On i386, there is no GLOB_DAT relocation against stdio with PIE. We
should compile tst-prelink.c without PIE.

North Frisian language code is "frr"
for fy_DE "fry" code is used which belongs to "Sater Frisian"
also data map to "Sater Frisian"
so "Sater Frisian and North Frisian Locale" renamed to
"Sater Frisian"

I'm not convinced this is a bug. The computer-only en_* locales are
notoriously underspecified.

since xgetbv takes much more cycles than single cycle operations like
vpord/vvpcmpeq/ptest. _dl_runtime_resolve_opt should be used only with
AVX512 where AVX512 instructions lead to lower CPU frequency on Skylake
server.

Bug 21053: sh: Reduce namespace pollution from sys/ucontext.h
The problem is basically that sys/ucontext.h is defining R0..R15
which happens to conflict with some packages like Firefox when
trying to build on SH.
The very same problem existed on arm back then [1] and it was fixed by
renaming R0..R15 to REG_R0..REG_R15. This patch imploy a similar
strategy for SH.
Checked on sh4-linux-gnu with run-built-tests=no and I also got reports
that it fixes Firefox build on Debian sh4.
* sysdeps/unix/sysv/linux/sh/sh3/ucontext_i.sym: Use new REG_R*
constants instead of the old R* ones.
* sysdeps/unix/sysv/linux/sh/sh4/ucontext_i.sym: Likewise.
* sysdeps/unix/sysv/linux/sh/sys/ucontext.h (NGPREG): Rename...
(NGREG): ... to this, to fit in with other architectures.
(gpregset_t): Use new NGREG macro.
[__USE_GNU]: Remove condition; all architectures other than tile
are unconditional.
(R*): Rename to REG_R*.
(cherry picked from commit 3e1b518550634792de13332edaab0ad722322c2b)

powerpc: Fix logbl on power7 [BZ# 21280]
1. Fix the results for negative subnormals by ignoring the signal when
normalizing the value.
2. Fix the output when the high part is a power of 2 and the low part
is a nonzero number with opposite sign. This fix is based on commit
380bd0fd2418f8988217de950f8b8ff18af0cb2b.
After applying this patch, logbl() tests pass cleanly on POWER >= 7.
Tested on powerpc, powerpc64 and powerpc64le
[BZ #21280]
* sysdeps/powerpc/power7/fpu/s_logbl.c (__logbl): Ignore the
signal of subnormals and adjust the exponent of power of 2 down
when low part has opposite sign.
(cherry picked from commit c064f6a613844181f411aabb2662384a6aefb69e)

--- Comment #18 from yjf.victor at foxmail dot com ---
This feature is pretty important actually. For many Asian companies, we have to
set the date format to yyyy-mm-dd (or maybe yyyy年mm月dd日) while sending
announcement, even when the announcement is in English language, such as some
international companies. Thus, it would be better to set the LC_TIME to ISO
8601 or RFC 3339 compatible format.
Currently, we set our date format to yyyy-MM-dd on Windows, and on Linux, the
"date" command is set as an alias, alias date='date --rfc-3339=seconds'. I
believe it would be better if we can set LC_TIME to something like "C@iso8601"
or maybe "POSIX@iso8601".
As for the format control of weekday name (%a) month name (%b) when you set
LC_TIME to C@iso8601, weekday name could be simply 0-6 (for Sunday to
Saturday), and month name could be the same as the month number, i.e. 1-12 (for
January to December). As a result, It isn't so difficult to have this locale.

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/

NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:

NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by

* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant

NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:

* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
“no-reload†(RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the “search†directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the ‘_res’ global
object are still limited to six search domains.
- When the “rotate†(RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
libc-alpha@sourceware.org and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact libc-alpha@sourceware.org.)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks (CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
fixed (CVE-2017-12133).

--- Comment #3 from Florian Weimer <fweimer at redhat dot com> ---
Note that gethosts is also buggy in this regard:
while (1) { \
rc = 0; \
status = DL_CALL_FCT (fct, (name, _family, &th, \
tmpbuf->data, tmpbuf->length, \
&rc, &herrno, NULL, &localcanon)); \
if (rc != ERANGE || herrno != NETDB_INTERNAL) \
break; \
if (!scratch_buffer_grow (tmpbuf)) \
{ \
result = -EAI_MEMORY; \
goto free_and_return; \
} \
} \
if (status == NSS_STATUS_SUCCESS && rc == 0) \
h = &th; \
else \
h = NULL; \
if (rc != 0) \
It assumes that rc (essentially errno) and herrno are valid for all status
return values. In reality, at least nss_files can return NSS_STATUS_SUCCESS
with clobbered errno and h_errno values.

Bug ID: 21885
Summary: getaddrinfo: gethosts does not release resolver
context on memory allocation failure
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
This is a pre-existing bug but arguably made worse by the resolver context
extension:
if (!scratch_buffer_grow (tmpbuf)) \
{ \
result = -EAI_MEMORY; \
goto free_and_return; \
} \
vs
if (herrno == NETDB_INTERNAL) \
{ \
__set_h_errno (herrno); \
__resolv_context_enable_inet6 (res_ctx, res_enable_inet6); \
__resolv_context_put (res_ctx); \
result = -EAI_SYSTEM; \
goto free_and_return; \
} \
The first error return path needs to call __resolv_context_* functions as well.

commit 2fee621de0776a6e729c3b18c27442e00733f2b2
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Aug 2 16:09:01 2017 +0000
Fix tgmath.h for bit-fields (bug 21685).
The tgmath.h macros produce errors for bit-field arguments, because
they apply sizeof and typeof to the arguments. This patch fixes them
to use unary + systematically before using sizeof or typeof on
arguments that might be bit-fields (note that __real__ of a bit-field
is still a bit-field for this purpose, since it's an lvalue).
gen-tgmath-tests.py is extended to add tests for this case.
Tested for x86_64.
[BZ #21685]
* math/tgmath.h (__tgmath_real_type): Use unary + on potentially
bit-field expressions passed to sizeof or typeof.
[__HAVE_FLOAT128 && __GLIBC_USE (IEC_60559_TYPES_EXT)]

since xgetbv takes much more cycles than single cycle operations like

This is as intended. And I would like this to be applied in most
yesexpr strings, for versability for the users
+ is ised in many applications for yes (- for no)
1 is common yes - langage neutral
Jj is Danish/German/Swedish/Norwegian/Dutch "ja"
sS is Spanish/Italian "si"
yY is English "yes"
oO is French "oui"

commit 42df8d5921d9ce28f44694ae943efb432b5e9aa7
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Aug 2 20:16:05 2017 +0000
Fix tgmath.h for __int128 (bug 21686).
When a tgmath.h macro is passed a double argument and an argument of
type __int128, it generates a call to a long double function (although
the result still gets converted to type double). __int128 is similar
enough to integer types that it should be handled consistently like
them, so always like double for these macros rather than sometimes
like double and sometimes like long double. This patch fixes the
logic accordingly and makes gen-tgmath-tests.py generate tests for
__int128.
Tested for x86_64 and x86.
[BZ #21686]
* math/tgmath.h (__TGMATH_BINARY_REAL_ONLY): Add arguments before
comparing size with that of double.
(__TGMATH_BINARY_REAL_STD_ONLY): Likewise.
(__TGMATH_BINARY_REAL_RET_ONLY): Likewise.
(__TGMATH_TERNARY_FIRST_SECOND_REAL_ONLY): Likewise.
(__TGMATH_TERNARY_REAL_ONLY): Likewise.
(__TGMATH_BINARY_REAL_IMAG): Likewise.
* math/gen-tgmath-tests.py (Type.init_types): Create __int128 and
unsigned __int128 types.

Summary: ppc64 setjmp/longjmp not fully interoperable with
static dlopen
Product: glibc
Version: unspecified
Status: UNCONFIRMED

Created attachment 10311
--> https://sourceware.org/bugzilla/attachment.cgi?id=10311&action=edit
testcase
On PowerPC64, implementations of setjmp and longjmp in Glibc save/restore
caller's saved TOC at ($r1+24) if compiled for shared libc.so, but not for
static libc.a. However, since static dlopen is supported, a situation may
arise when libc.a longjmp is returning to a call site of libc.so setjmp; in
that case caller's saved TOC at ($r1+24) is not restored and the caller may
segfault. The attached testcase demonstrates this issue.

Bug ID: 21898
Summary: NSS functions set errno to 0
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: nss
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Created attachment 10313
--> https://sourceware.org/bugzilla/attachment.cgi?id=10313&action=edit
test-nss-errno.c
The attached test case shows that gethostbyname, gethostbyname_r, and getpwnam
set errno to 0 upon success. POSIX does not allow this. getpwnam is in POSIX,
so this is a compliance issue.
errno after gethostbyname: 0
gethostbyname_r returns: 0
errno after gethostbyname_r: 0
errno after getpwnam: 0
This comes from the code in nss/getXXbyYY_r.c:
int res;
if (status == NSS_STATUS_SUCCESS || status == NSS_STATUS_NOTFOUND)
res = 0;
/* Don't pass back ERANGE if this is not for a too-small buffer. */
else if (errno == ERANGE && status != NSS_STATUS_TRYAGAIN)
res = EINVAL;
#ifdef NEED_H_ERRNO
/* These functions only set errno if h_errno is NETDB_INTERNAL. */
else if (status == NSS_STATUS_TRYAGAIN && *h_errnop != NETDB_INTERNAL)
res = EAGAIN;
#endif
else
return errno;
__set_errno (res);
return res;
We should probably check for res != 0 before calling __set_errno.

Bug ID: 21902
Summary: RFE: set_fileno(fp, fd). use case: shell needs to
change fd in a FILE
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: vda.linux at googlemail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
I'm using ordinary FILE i/o for reading scripts in the code of hush shell,
instead of rolling my own implementation, so that I can reuse buffering code in
libc, through the use of fgetc().
This works for almost all cases, except this one: if in script I have a
redirect which says shell wants to open a fd which happens to be equal to the
fd (say, 10) shell already used for script FILE object:
exec 10>FILE
What other shells do in this situation is they simply dup and close script fd
[in real code, they use fcntl(F_DUPFD) instead of dup() since they want to
avoid getting low fds], so that fd is "moved" and no longer collides with the
redirect.
I can do this trick, but since I use FILE interface, then I need to inform libc
that it needs to use new fd for this FILE.
"fileno(fp) = new_fd;" is non-portable and does not work in glibc: it's a
function, not a macro referencing (fp)->field_holding_fd.
"fclose(fp); fp = fdopen(new_fd);" is not good since fp may have some buffered
input, which will be lost by such code.
How about adding a "set_fileno(fp, fd)" extension, with some easy define to
probe for to conditionally use it?
To make life easier for implementers, I propose that API definition of it
should say that any buffered input or output data is not discarded
or sent to previous fd during/after the call - the function only
changes internal fd. It does neither flushing nor seeking nor discarding of
buffers. Essentially, user has to take care and fflush(fp)
before he starts messing with fds, or buffered data may end up up written to a
wrong fd.
While bouncing around this idea on IRC with other people, some said it could be
a thing which would help them with another problem they had. They had a FILE
object which they wanted to stop using and free it, but to _not_ close the
underlying fd. Along the lines of:
fflush(fp);
fd = fileno(fp);
fclose_but_not_close(fp);
and having fd still open. (They could not work around with dup(fd) before
fclose(), since this was in a library code, fd had to stay the same due to
concurrency and API issues).
They say that if set_fileno() would exist and would allow set_fileno(fp, -1),
it would do what they want.

snprintf is terribly slow when copying strings. I tried to copy strings of
various length using strcpy, strncat and snprintf, and snprintf is way slower
than other two. Below are my results. Tested on RHEL 7.2, CPU Xeon E5-4627v2,
gcc 4.8.5, glibc 2.17-106.el7_2.8.

since xgetbv takes much more cycles than single cycle operations like

_start is the entry point before the executable is relocated.

Compile tst-prelink.c without PIE [BZ #21815]
tst-prelink.c checks for conflict with GLOB_DAT relocation against stdio.
On i386, there is no GLOB_DAT relocation against stdio with PIE. We
should compile tst-prelink.c without PIE.
[BZ #21815]
* elf/Makefile (CFLAGS-tst-prelink.c): New.
(LDFLAGS-tst-prelink): Likewise.

sunrpc: Avoid use-after-free read access in clntudp_call [BZ #21115]
After commit bc779a1a5b3035133024b21e2f339fe4219fb11c
(CVE-2016-4429: sunrpc: Do not use alloca in clntudp_call
[BZ #20112]), ancillary data is stored on the heap,
but it is accessed after it has been freed.
The test case must be run under a heap debugger such as valgrind
to observe the invalid access. A malloc implementation which
immediately calls munmap on free would catch this bug as well.
(cherry picked from commit d42eed4a044e5e10dfb885cf9891c2518a72a491)

Bug ID: 21908
Summary: dynamic linker broke on ia64 (mmap2 consolidation is
the suspect)
Product: glibc
Version: 2.27
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: slyfox at inbox dot ru
Target Milestone: ---
Tried to build/test vanilla glibc on ia64. All binaries crash with new rtld.
$ git describe
glibc-2.26-36-g219dd320d6
strace differece of working versus non-working:
OK: mmap(0x600000000000c000, 16384, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3</root/glibc-build/locale/localedef>,
0x9c000) = 0x600000000000c000
BAD: mmap2(0x600000000000c000, 16384, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3</root/glibc-build/locale/localedef>,
0x270000) = 0x600000000000c000
The suspect is mmap2() consolidation:
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=158d5fa0e1906e7810bdc6ecb7bf598dcc3cd17d
Note the offset difference. 0x270000 / 0x9c000 = 4. ia64 pages are 16K.
Looking at various implementations of mmap2() in linux kernel it feels like
it varies from architecture to architecture what page units are in mmap2(...,
off_t pgoffset):
4K or PAGE_SIZE.
Does the above make any sense?
How I found it:
$ make check
...
../localedata/gen-locale.sh: line 29: 27804 Bus error (core
dumped) ${localedef_before_env} ${run_program_env} I18NPATH=../localedata
${localedef_after_env} --quiet -c -f $charmap -i $input
${common_objpfx}localedata/$out
...
Bus error is caused by an attempt to write into mapped area not backed
by actual file. gdb backtrace:

Correction to the comment on page size on ia64 and mmap2 units:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/ia64/include/asm/page.h#n29

[ Kconfig help text:

--- Comment #2 from Andreas Schwab <schwab@linux-m68k.org> ---
Generically, mmap2 is supposed to take units of 4K, but a few architectures got
this wrong, including m68k and ia64. Copy from
sysdeps/unix/sysv/linux/m68k/mmap_internal.h.

That was my first attempt, yes. But does m68k work?
MMAP2_PAGE_SHIFT is not used anywhere in glibc source code at all.
I suspect mmap_internal.h should have set MMAP2_PAGE_UNIT to -1
to have any effect on pagesize detection.
But if I apply that for m68 (or ia64):

glibc-git-mmap2-on-ia64.patch
Made it work based on m68k with this patch! Had to fix m68k as well.
It's not very clean but it implements two ideas:
- m68k: fix typo to use MMAP2_PAGE_UNIT, not MMAP2_PAGE_SHIFT (not used
anywhere)
- ia64: fix usage of page_unit instead of MMAP2_PAGE_UNIT in mmap() calls
What I don't like about the patch as-is:
- had to add '__attribute__((used));' to 'static int page_unit' as it's not
always used (#ifdefs are all around)
- page_unit has type either 'int' (MMAP2_PAGE_UNIT -1) or 'unsigled long long'
(MMAP2_PAGE_UNIT 4096ULL) that requires. This requires cmplicated cast in:
#define MMAP_OFF_HIGH_MASK \
((-((unsigned long long)page_unit << 1) << (8 * sizeof (off_t) - 1)))

--- Comment #5 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
Indeed, current m68k is wrong and although I did test on a system I have access
I got lucky because it uses the default 4k page size (it is not a coldfire
one). However I think the patch below is slight intrusive:

The basis tst-mmap and tst-mmap-offset passes on the m68k I have acess. And I
think it should work on ia64 as well. What do you think?

--- Comment #7 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
I was puzzled why for ia64 and m68k the mmap2 is not working on multiple of 4K
as for other arches (for instance powerpc) and it seems indeed that for ia64
and m68k the underlying semantic of mmap2 is indeed dependent of kernel
PAGE_SHIFT definition. For instance, m68k mmap2 implementation:
arch/m68k/kernel/sys_m68k.c:
39 asmlinkage long sys_mmap2(unsigned long addr, unsigned long len,
40 unsigned long prot, unsigned long flags,
41 unsigned long fd, unsigned long pgoff)
42 {
43 /*
44 * This is wrong for sun3 - there PAGE_SIZE is 8Kb,
45 * so we need to shift the argument down by 1; m68k mmap64(3)
46 * (in libc) expects the last argument of mmap2 in 4Kb units.
47 */
48 return sys_mmap_pgoff(addr, len, prot, flags, fd, pgoff);
49 }
And ia64:
arch/ia64/kernel/sys_ia64.c
133 /*
134 * mmap2() is like mmap() except that the offset is expressed in units
135 * of PAGE_SIZE (instead of bytes). This allows to mmap2() (pieces
136 * of) files that are larger than the address space of the CPU.
137 */
138 asmlinkage unsigned long
139 sys_mmap2 (unsigned long addr, unsigned long len, int prot, int flags, int
fd, long pgoff)
140 {
141 addr = sys_mmap_pgoff(addr, len, prot, flags, fd, pgoff);
142 if (!IS_ERR((void *) addr))
143 force_successful_syscall_return();
144 return addr;
145 }
While for powerpc it adjusts the pgoff to be independent of PAGE_SHIFT:
arch/powerpc/kernel/syscalls.c
65 SYSCALL_DEFINE6(mmap2, unsigned long, addr, size_t, len,
66 unsigned long, prot, unsigned long, flags,
67 unsigned long, fd, unsigned long, pgoff)
68 {
69 return do_mmap2(addr, len, prot, flags, fd, pgoff, PAGE_SHIFT-12);
70 }
I will send a patch upstream fixing it.

Yeah, I am aware and neither is my intention. Just trying to get context why
special handling is required for the syscall om m68k and ia64.

--- Comment #6 from Ken Milmore <ken.milmore at gmail dot com> ---
The kernel change does appear to have fixed the regression, in so much as
clients of nscd will no longer continue to use a stale cache *forever* if the
nscd daemon is killed.
However, I think it is worth pointing out that following an abrupt death of
nscd, clients will still wait for 5 minutes (MAPPING_TIMEOUT) before dropping a
stale cache. This is because of the way the check of the nscd_certainly_running
flag is implemented. See nscd_helper.c:
414 /* If not mapped or timestamp not updated, request new map. */
415 if (cur == NULL
416 || (cur->head->nscd_certainly_running == 0
417 && cur->head->timestamp + MAPPING_TIMEOUT < time (NULL))
418 || cur->head->data_size > cur->datasize)
419 cur = __nscd_get_mapping (type, name,
420 (struct mapped_database **)
&mapptr->mapped);
Note that for the cache to be dropped, the nscd_certainly_running flag needs to
be zero *and* the timeout needs to have expired. If the nscd server is shut
down cleanly, both of these fields are cleared (the timestamp is cleared
manually by termination_handler() in nscd.c and the flag is cleared via the TID
mechanism). But if the server dies abruptly, only the flag gets cleared so we
have to wait for the timeout to expire.
It can be seen that in terms of rejecting stale caches, there is no advantage
here over simply ignoring the nscd_certainly_running flag completely. The only
purpose of the flag seems to be to optimise away the need for the call to
time() each time a lookup is performed. Since these days time() is likely to
be VDSO optimised (via gettimeofday()), the whole fragile mechanism would not
seem to be well justified on performance grounds. A better approach might have
been to point the TID address at the timestamp field itself: that way, the time
stamp would be guaranteed to get zeroed out even on abrupt termination, and the
stale cache would always be detected immediately by clients.

cannot find -lnss_test2
collect2: error: ld returned 1 exit status
Execution of gcc failed!
The script has found some problems with your installation!
Please read the FAQ and the README file and check the following:
- Did you change the gcc specs file (necessary after upgrading from
Linux libc5)?
- Are there any symbolic links of the form libXXX.so to old libraries?
Links like libm.so -> libm.so.5 (where libm.so.5 is an old library) are
wrong,
libm.so should point to the newly installed glibc file - and there should be
only one such link (check e.g. /lib and /usr/lib)
You should restart this script from your build directory after you've
fixed all problems!
Btw. the script doesn't work if you're installing GNU libc not as your
primary library!
make[1]: *** [Makefile:111: install] Error 1
System is working after this error.
But I think this should be fixed.
When libnss_test2 was added, this library should have been filtered out for the
test.
Please find my patch attached.

since xgetbv takes much more cycles than single cycle operations like
vpord/vvpcmpeq/ptest. _dl_runtime_resolve_opt should be used only with

Bug ID: 21913
Summary: static bianries SIGSEV in __brk when host gcc is
pie-by-default (i386)
Product: glibc
Version: 2.27
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc

CC: drepper.fsp at gmail dot com
Target Milestone: ---
I think __sbrk is called in __libc_setup_tls before setting up %gs/TLS
properly.
Causes early SIGSEGV at startup.
Noticed SIGSEGV when tried to install glibc-git in i386:
Crash happens at stage when 'elf/sln' is called (at 'make install' phase):
$ gdb --args elf/sln elf/symlink.list
Program received signal SIGSEGV, Segmentation fault.

31 int
32 __brk (void *addr)
33 {
34 INTERNAL_SYSCALL_DECL (err);
35 void *newbrk = (void *) INTERNAL_SYSCALL (brk, err, 1, addr);
36 __curbrk = newbrk;
37 if (newbrk < addr)
38 return INLINE_SYSCALL_ERROR_RETURN_VALUE (ENOMEM);
39 return 0;
Note that for INTERNAL_SYSCALL 'call *%gs:0x10' is used.
AFAIU gs is supposed to be initialized by glibc itself for main thread.
But __sbrk system call is used before tls area is set.

This change looks relevant:
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=627c69c838e75d69f46a7cc7dd2bafca03adbf60
as it allows sysenter to be used for static binaries as well.

i386: Add _startup_sbrk and _startup_fatal [BZ #21913]
On Linux/x86, there are 3 ways to make a system call:
1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization.
2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo.
3. int $0x80. This works everywhere.
When an object file is compiled with PIC, #1 is prefered since it is
faster than #3 and doesn't require relocation of _dl_sysinfo. For
dynamic executables, ld.so initializes TLS. However, for static
executables, before TLS is initialized by __libc_setup_tls, #3 should
be used for syscalls. This patch adds _startup_sbrk and _startup_fatal
to be used in static executables before __libc_setup_tls is called. By
default, they are defined to __sbrk and __libc_fatal, respectively. On
x86, a special _startup_sbrk is provided and _startup_fatal is turned
into ABORT_INSTRUCTION.
[BZ #21913]
* csu/libc-tls.c: Include <startup.h>.
(__libc_setup_tls): Call _startup_sbrk instead of __sbrk. Call
_startup_fatal instead of __libc_fatal.
* elf/dl-tunables.c: Include <startup.h>.
(tunables_strdup): Call _startup_sbrk instead of __sbrk.
* sysdeps/generic/startup.h: New file.
* sysdeps/unix/sysv/linux/i386/startup.h: Likewise.
* sysdeps/unix/sysv/linux/i386/startup_sbrk.c: Likewise.
* sysdeps/unix/sysv/linux/i386/Makefile (sysdep_routine): Add
startup_sbrk if default to PIC.

i386: Add _startup_sbrk and _startup_fatal [BZ #21913]
On Linux/x86, there are 3 ways to make a system call:
1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization.
2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo.
3. int $0x80. This is slower than #2 and #3, but works everywhere.
When an object file is compiled with PIC, #1 is prefered since it is
faster than #3 and doesn't require relocation of _dl_sysinfo. For
dynamic executables, ld.so initializes TLS. However, for static
executables, before TLS is initialized by __libc_setup_tls, #3 should
be used for syscalls. This patch adds _startup_sbrk and _startup_fatal
to be used in static executables before __libc_setup_tls is called. By
default, they are defined to __sbrk and __libc_fatal, respectively. On
x86, a special _startup_sbrk is provided and _startup_fatal is turned
into ABORT_INSTRUCTION.
[BZ #21913]
* csu/libc-tls.c: Include <startup.h>.
(__libc_setup_tls): Call _startup_sbrk instead of __sbrk. Call
_startup_fatal instead of __libc_fatal.
* elf/dl-tunables.c: Include <startup.h>.

--- Comment #11 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Once the fix is in, could someone do an ulps regeneration for ia64 (master
and 2.26 branch) and post 2.26 branch test results to
<https://sourceware.org/glibc/wiki/Release/2.26> to indicate the current
state of the port? (Of course, making any other fixes needed to get the
results to a cleaner state would be even better.)
We need people running the full testsuite for each port during the release
freeze every six months, and preferably addressing any major breakage
shown.

--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Those double functions are probably optimized for FMA because they use
DLA_FMS, or the other macros that have definitions depending on DLA_FMS.
That is, they can use fused operations directly, not just via contraction.
Since the float functions are completely separate implementations, none of
them using fused operations, there is no reason to expect that FMA
versions of them would be helpful just based on the corresponding double
versions using FMA (although it's possible there are smaller optimization
opportunities arising from contraction - not necessarily for the same set
of functions).

Bug ID: 21915
Summary: nss_files can return with NSS_STATUS_SUCCESS and a
clobbered errno value, causing getaddrinfo to fail
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: nss
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
getaddrinfo has this code:
while (1) { \
rc = 0; \
status = DL_CALL_FCT (fct, (name, _family, &th, \
tmpbuf->data, tmpbuf->length, \
&rc, &herrno, NULL, &localcanon)); \
if (rc != ERANGE || herrno != NETDB_INTERNAL) \
break; \
if (!scratch_buffer_grow (tmpbuf)) \
{ \
result = -EAI_MEMORY; \
goto free_and_return; \
} \
} \
if (status == NSS_STATUS_SUCCESS && rc == 0) \
h = &th; \
else \
h = NULL; \
if (rc != 0) \
That is, *errnop (in the form of rc) takes precedence over the NSS return
status.
nss_files, in multi mode, will continue reading /etc/hosts after the first
match, to find additional addresses and aliases. These subsequent reads can
perform ERANGE-based buffer resizing. This means that errno is not 0 anymore,
and getaddrinfo will report an incorrect error.
I initially added this to bug 20532 comment 3, but it is not clear what this
bug is actually about anymore, so I'm tracking this separately.

commit 99dd28489e425c6f654126871f89d514331aa69f
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Wed Jul 19 14:32:42 2017 -0700
i386: Add <startup.h> [BZ #21913]
On Linux/i386, there are 3 ways to make a system call:
1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization.
2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo.
3. int $0x80. This is slower than #2 and #3, but works everywhere.
When an object file is compiled with PIC, #1 is prefered since it is
faster than #3 and doesn't require relocation of _dl_sysinfo. For
dynamic executables, ld.so initializes TLS. However, for static
executables, before TLS is initialized by __libc_setup_tls, #3 should
be used for syscalls.
This patch adds <startup.h> which defines _startup_fatal and defaults
it to __libc_fatal. It replaces __libc_fatal with _startup_fatal in
static executables where it is called before __libc_setup_tls is called.
This header file is included in all files containing functions which are
called before __libc_setup_tls is called. On Linux/i386, when PIE is
enabled by default, _startup_fatal is turned into ABORT_INSTRUCTION and
I386_USE_SYSENTER is defined to 0 so that "int $0x80" is used for system
calls before __libc_setup_tls is called.
[BZ #21913]
* config.h.in (BUILD_PIE_DEFAULT): New.
* csu/libc-tls.c: Include <startup.h>.
* elf/dl-tunables.c: Likewise.
* sysdeps/unix/sysv/linux/i386/brk.c: Likewise.
* csu/libc-tls.c: Include <startup.h>.
(__libc_setup_tls): Call _startup_fatal instead of __libc_fatal.
* sysdeps/generic/startup.h: New file.
* sysdeps/unix/sysv/linux/i386/startup.h: Likewise.

i386: Add _startup_sbrk and _startup_fatal [BZ #21913]
On Linux/i386, there are 3 ways to make a system call:
1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization.
2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo.
3. int $0x80. This is slower than #2 and #3, but works everywhere.
When an object file is compiled with PIC, #1 is prefered since it is
faster than #3 and doesn't require relocation of _dl_sysinfo. For
dynamic executables, ld.so initializes TLS. However, for static
executables, before TLS is initialized by __libc_setup_tls, #3 should
be used for syscalls. This patch adds _startup_sbrk and _startup_fatal
to be used in static executables before __libc_setup_tls is called. By
default, they are defined to __sbrk and __libc_fatal, respectively. On
Linux/i386, a special _startup_sbrk is provided and _startup_fatal is
turned into ABORT_INSTRUCTION.
[BZ #21913]
* csu/libc-tls.c: Include <startup.h>.
(__libc_setup_tls): Call _startup_sbrk instead of __sbrk. Call
_startup_fatal instead of __libc_fatal.
* elf/dl-tunables.c: Include <startup.h>.
(tunables_strdup): Call _startup_sbrk instead of __sbrk.
* sysdeps/generic/startup.h: New file.
* sysdeps/unix/sysv/linux/i386/startup.h: Likewise.
* sysdeps/unix/sysv/linux/i386/startup_sbrk.c: Likewise.
* sysdeps/unix/sysv/linux/i386/Makefile (sysdep_routine): Add
startup_sbrk if default to PIE.
(static-only-routines): Likewise.

commit cd65836b5fba2d34a4c04c15b47723ab9237b66a
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Aug 7 23:41:32 2017 +0000
Fix XPG4.2 bits/sigaction.h namespace (bug 21899).
For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and
SA_NODEFER should be defined in signal.h, but they are only defined
for other standards at present.
This patch fixes the various bits/sigaction.h headers accordingly.
All the fixes are essentially the same, except those for SPARC and
Tile.
For SPARC, the header (a) spuriously defined various nonstandard
macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some
standard macros as aliases of nonstandard ones instead of the other
way round. This patch fixes the SPARC header to handle these macros
the same way and with the same conditions as those for other
architectures, so the standard macros are the primary ones and the
other ones are defined only for __USE_MISC and are aliases of the
standard ones where applicable.
For Tile, the header spuriously defined the nonstandard macro
SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved
to __USE_MISC.
(Those nonstandard macros are in a reserved namespace, but it seems
desirable to be consistent between architectures as far as possible,
and so not define them in standard modes anywhere.)
Tested for x86_64, and with build-many-glibcs.py.

Should this stroke count sorting also be applied to zh_TW, or
only to cmn_TW?

Thank you!
Should the new collation also be used for zh_TW, or only
for cmn_TW.
By the way, what is the difference between zh_TW
and cmn_TW, isn’t both Mandarin?

Note that behavior is different for AF_UNSPEC and AF_INET/AF_INET6. AF_UNSPEC
is probably more accurate at present because the gethosts macro in getaddrinfo
has incorrect error detection logic.

If the network is down and name resolution cannot before, EAI_NONAME is
certainly not the right error code to return. It should be EAI_SYSTEM or
EAI_FAIL.

Bug ID: 21922
Summary: getaddrinfo with AF_INET/AF_INET6 returns EAI_NONAME
instead of EAI_NODATA
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
If the name exists, but does not have the requested address type associated
with it, getaddrinfo returns EAI_NONAME instead of EAI_NODATA for non-AF_UNSPEC
lookups. (This seems to work correctly for AF_UNSPEC lookups.)

commit 852d63120783fae5bf85a067320dc4ba1ed59f11
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Mon Jul 17 10:59:59 2017 -0300
posix: Set p{read,write}v2 to return ENOTSUP (BZ#21780)
Different than other architectures hppa-linux-gnu define different values
for ENOTSUP and EOPNOTSUPP, where the later is a Linux specific one.
This leads to tst-preadwritev{64}v2 tests failures:
$ ./testrun.sh misc/tst-preadvwritev2
error: tst-preadvwritev2-common.c:35: preadv2 failure did not set errno to
ENOTSUP (223)
error: 1 test failures
The straightforward fix is to return the POSIX defined ENOTSUP on all
p{read,write}v{64}v2 implementations instead of Linux specific one.
Checked on x86_64-linux-gnu and the tst-preadwritev{64}v2 on
hppa-linux-gnu (although due the installed kernel on my testing system
the pwritev{64}v2 with an invalid flag still fails due a known kernel
issue [1]).
[BZ #21780]
* sysdeps/posix/preadv2.c (preadv2): Use ENOTSUP instead of
EOPNOTSUPP.
* sysdeps/posix/preadv64v2.c (preadv64v2): Likewise.
* sysdeps/posix/pwritev2.c (pwritev2): Likewise.
* sysdeps/posix/pwritev64v2.c (pwritev64v2): Likewise.
* sysdeps/unix/sysv/linux/preadv2.c (preadv2): Likewise.
* sysdeps/unix/sysv/linux/preadv64v2.c (preadv64v2): Likewise.

Bug ID: 21926
Summary: getaddrinfo: INET/INET6 status consolidation does not
update errno, h_errno
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
There is a bit of code to consolidate status between AF_INET and AF_INET6
responses:
{
/* We can have different states for AF_INET and
AF_INET6. Try to find a useful one for both. */
if (inet6_status == NSS_STATUS_TRYAGAIN)
status = NSS_STATUS_TRYAGAIN;
else if (status == NSS_STATUS_UNAVAIL
&& inet6_status != NSS_STATUS_UNAVAIL)
status = inet6_status;
}
AF_INET6 is queried first, then AF_INET. This means that if ient6_status ==
NSS_STATUS_TRYAGAIN, the errno and h_errno values may have been clobbered by
the AF_INET.
We probably should not perform the second query if the first query with
NSS_STATUS_TRYAGAIN or NSS_STATUS_UNAVAIL.

Don't use IFUNC resolver for longjmp or system in libpthread (bug 21041)
Unlike the vfork forwarder and like the fork forwarder as in bug 19861,
there won't be a problem when the compiler does not turn this into a tail
call.

As reasons for bug 15963, those 14 languages have been behind the
macro-language "zh" for a long time. Technically zh_TW and cmn_TW are the same,
but for fairness, IMHO, the locale zh_TW should be deprecated and replaced with
cmn_TW and other chinese locales.
Personally I would like to differentiate cmn from zh with this radical patch,
which may be followed by similar patches against nan_TW, hak_TW, lzh_TW and
yue_HK.

commit 086df229eef36041cae4a633c6fde6150f18d75e
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Tue Aug 8 08:41:08 2017 -0700
i386: Add <startup.h> [BZ #21913]
On Linux/i386, there are 3 ways to make a system call:
1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization.
2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo.
3. int $0x80. This is slower than #2 and #3, but works everywhere.
When an object file is compiled with PIC, #1 is prefered since it is
faster than #3 and doesn't require relocation of _dl_sysinfo. For
dynamic executables, ld.so initializes TLS. However, for static
executables, before TLS is initialized by __libc_setup_tls, #3 should
be used for system calls.
This patch adds <startup.h> which defines _startup_fatal and defaults
it to __libc_fatal. It replaces __libc_fatal with _startup_fatal in
static executables where it is called before __libc_setup_tls is called.
This header file is included in all files containing functions which are
called before __libc_setup_tls is called. On Linux/i386, when PIE is
enabled by default, _startup_fatal is turned into ABORT_INSTRUCTION and
I386_USE_SYSENTER is defined to 0 so that "int $0x80" is used for system
calls before __libc_setup_tls is called.
Tested on i686 and x86-64. Without this patch, all statically-linked
tests will fail on i686 when the compiler defaults to -fPIE.
[BZ #21913]
* csu/libc-tls.c: Include <startup.h> first.
(__libc_setup_tls): Call _startup_fatal instead of __libc_fatal.
* elf/dl-tunables.c: Include <startup.h> first.
* include/libc-symbols.h (BUILD_PIE_DEFAULT): New.
* sysdeps/generic/startup.h: New file.
* sysdeps/unix/sysv/linux/i386/startup.h: Likewise.
* sysdeps/unix/sysv/linux/i386/brk.c [BUILD_PIE_DEFAULT != 0]
(I386_USE_SYSENTER): New. Defined to 0.

--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
There are two different bugs in the code: The incorrect error handling in
gethosts (bug 21915) and incorrect reporting of a zero return status from
gethostbyname_r because h_errno is ignored.

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

Add private_function for private functions within glibc [BZ #21598]
USE_REGPARMS in config.h.in is only used to control how parameters are
passed for internal functions on i386. On i386, we define
# define internal_function __attribute__ ((regparm (3), stdcall))
so that we pass up to 3 integer parameters in registers for internal
functuons on i386. i386 has
_dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
which is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding when shadow
stack is enabled. However, internal_function, which should be used only
with hidden function within libc.so, are also used with private function
calls between different shared objects of glibc.
This patch removes USE_REGPARMS from config.h.in. Instead, it defines
internal_function and private_function, which is for private function
calss between different shared objects, in config.h.in. Currently,
sysdeps/i386/configure.ac defines private_function as
# define private_function __attribute__ ((regparm (3), stdcall))
There is no change in shared objects on Linux/i686 nor Linux/x86_64.
When shadow stack is enabled, private_function will be defined as
# define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used as scratch register by _dl_runtime_resolve.

commit 9995c839a01cd8db17120cb2c0a80f81d858b179
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Tue May 16 16:05:35 2017 -0300
manual: Document getcontext uc_stack value on Linux [BZ #759]
As decribed in BZ#759, Linux getcontext implementation on Linux does
differs from other SysV system about the returned uc_stack. This is
true not only for i386, but for all the architecture I could actually
check (aarch64, arm, alpha, hppa, m68k, mips, mips64, mips64n32,
powerpc, powerpc64, powerpc64le, s390x, sh, sparc, sparc64, and x86).
And I think we should not change current behavior for some reasons:
1. POSIX 2008 removed this SySV interface for a good reason and changing
this behavior adds nothing for current portable code. POSIX 2001
specification does states that stack should be saved [1] and current
GLIBC code does in a arch-specific manner (inside the mcontext_t)
which allows the setcontext to work correctly.
2. Changing this behavior would potentially require compat symbols and
I see no gain in adding compat symbols for deprecated interfaces.
3. Also, for comment #2 in BZ#759, it is up to kernel do setup the contents
for ucontext_t and currently it does not provide the stack information
as well. Trying to change it is also another fix that does not worth
the possible gains.
Instead my proposal is to make it clear the current interface may differ
depending of the underlying operational system.
glibc documentation and close this bug as invalid.
[BZ #759]
* manual/setjmp.texi (getcontex): Document uc_stack value on Linux.

Bug ID: 21928
Summary: sys/ptrace.h: remove obsolete temporary development
Linux constant PTRACE_SEIZE_DEVEL
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: ldv at sourceware dot org
Reporter: ldv at sourceware dot org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
PTRACE_SEIZE_DEVEL shouldn't have been added to sys/ptrace.h in the first
place.
It was added to linux/ptrace.h for the only purpose of testing PTRACE_SEIZE API
which was in an experimental status.
>From the very first linux commit (v3.1-rc1~308^2~28) when it was introduced
till the very last one (v3.4-rc1~109^2~20) when it was removed, the definition
of PTRACE_SEIZE_DEVEL in linux/ptrace.h remained unchanged:
#define PTRACE_SEIZE_DEVEL 0x80000000 /* temp flag for development */
It was just a temporary flag for development. Those who play with experimental
kernel interfaces marked this way, e.g. strace, surely did not, do not, and
should not rely on sys/ptrace.h as the source of definitions of ptrace
constants.
The person who blindly updated sys/ptrace.h constants by commit glibc-2.15~430
did the wrong thing. The presence of PTRACE_SEIZE_DEVEL in sys/ptrace.h is a
bug, it has to be fixed and maybe even backported to stable branches.

Remove “% Charset: ...†comments from locale sources
These comments are useless and only confusing. The encodings used to
create binary locales from source locales are listed in the
localedata/SUPPORTED file. The source files itself are ASCII or UTF-8
encoded where non-ASCII UTF-8 is currently only used in comments. If
all locale source files are UTF-8 anyway, there is no need to specify
that in a special comment.

OK.
How to test your patch?
I did this:
Without your patch:
$ echo -e "黄\n木\n機\n期" | LC_ALL=cmn_TW.UTF-8 sort
期
木
æ©Ÿ
黄
$
With your patch:
$ echo -e "黄\n木\n機\n期" | LC_ALL=cmn_TW.UTF-8 sort
木
黄
期
æ©Ÿ
$
That seems to show that I applied your patch correctly, right?

If we got with government web link MONETARY is same across india
I added some Reference

https://en.wikipedia.org/wiki/Indian_rupee
best example currency note
p_sep_by_space is 0 exmaple :
₹10, ₹20, ₹50, ₹100, ₹500, ₹2000

Bug ID: 21930
Summary: C-only gcc builtins used in <math.h> isinf
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: leah at vuxu dot org
Target Milestone: ---
Since glibc 2.26, <math.h> uses __builtin_types_compatible_p and __typeof for
isinf, which are GCC extensions that GCC 6.3 only provides in C mode. This
means <math.h> cannot be used from C++ programs.
Whether this in itself is harmful is questionable, but it certainly is a
regression and implies at least one serious implication: the GCC 6.3
libstdc++v3 configure check "for ISO C99 support in <math.h> for C++98" now
fails, resulting in a libstdc++ <cmath> header that simply includes <math.h>,
which makes every C++ program fail to compile that correctly uses <cmath>.

commit 82efa1ffd43bed1494d20a4b86f6b15ac6bb5545
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Mon Jul 17 10:59:59 2017 -0300
posix: Set p{read,write}v2 to return ENOTSUP (BZ#21780)
Different than other architectures hppa-linux-gnu define different values
for ENOTSUP and EOPNOTSUPP, where the later is a Linux specific one.
This leads to tst-preadwritev{64}v2 tests failures:
$ ./testrun.sh misc/tst-preadvwritev2
error: tst-preadvwritev2-common.c:35: preadv2 failure did not set errno to
ENOTSUP (223)
error: 1 test failures
The straightforward fix is to return the POSIX defined ENOTSUP on all
p{read,write}v{64}v2 implementations instead of Linux specific one.
Checked on x86_64-linux-gnu and the tst-preadwritev{64}v2 on
hppa-linux-gnu (although due the installed kernel on my testing system
the pwritev{64}v2 with an invalid flag still fails due a known kernel
issue [1]).
[BZ #21780]
* sysdeps/posix/preadv2.c (preadv2): Use ENOTSUP instead of
EOPNOTSUPP.
* sysdeps/posix/preadv64v2.c (preadv64v2): Likewise.
* sysdeps/posix/pwritev2.c (pwritev2): Likewise.
* sysdeps/posix/pwritev64v2.c (pwritev64v2): Likewise.
* sysdeps/unix/sysv/linux/preadv2.c (preadv2): Likewise.
* sysdeps/unix/sysv/linux/preadv64v2.c (preadv64v2): Likewise.
* sysdeps/unix/sysv/linux/pwritev2.c (pwritev2): Likewise.
* sysdeps/unix/sysv/linux/pwritev64v2.c (pwritev64v2): Likewise.

The generic get*_r function calls __resolv_context_get without a matching
__resolv_context_put on all return paths.
This was found during code review. The impact is a minor memory leak.

--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
tst-getpw expects that getpw sets errno to 0, and I had to patch getpw to
restore that documented behavior. This suggests that fixing this POSIX
conformance issue is a high-risk behavioral change.

O_PATH will do the trick for kernels 3.6 and newer; here's a discussion where
qemu implemented a solution similar to Rich's pseudo-solution:
https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg01600.html
https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg01812.html
In the qemu case, the code is enforcing that no symlinks are dereferenced, so
it is not quite the same as the general solution for making AT_SYMLINK_NOFOLLOW
be implemented correctly, but the point remains that the fstat() test for
symlinks followed by chmod(/proc/self/fd) is viable and avoids TOCTTOU races.
Since the kernel has not yet accepted Greg's patch for a new fchmodat2()
syscall, we could at least enhance the user-space wrapper to do the right
thing.

Bug ID: 21936
Summary: gcc build hangs with glibc 2.26 (conftest about static
binaries dlopening themselves)
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: felix-glibc at fefe dot de
CC: drepper.fsp at gmail dot com
Target Milestone: ---
I recently upgraded to glibc 2.26. I have had this issue for a long while, but
it went away with glibc 2.25 or so I thought. Now it's back.
Basically, when I try to compile gcc from the sources, in multiple
subdirectories there are autoconf tests that are trying to find out whether a
statically linked binary can dlopen itself. The conftest from those tests
hangs.
I looked through previous bugs, and they make a mention of gold from binutils.
I am using gcc 7.1 and binutils 2.29 (and I was trying to compile the current
gcc from svn). ld is:
GNU ld (GNU Binutils) 2.29
(not gold).
This problem basically breaks unattended builds and is VERY annoying for that
reason. I'm not even sure why gcc would want to know if static binaries can
dlopen themselves.

--- Comment #1 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
Gabriel, I had thought this usage - and the definition of
__HAVE_GENERIC_SELECTION, which relates to a C-only feature but is not
conditional on C in any way - was harmless because C++ doesn't actually use
these macros (libstdc++ undefines them in its headers and defines its own
function overloads). Or, at least, that it was harmless except for
issignaling, which libstdc++ doesn't handle. But given the configure test,
maybe that needs revisiting.
(a) Don't define __HAVE_GENERIC_SELECTION for C++.
(b) The use of __builtin_choose_expr is unnecessary, a conditional expression
should suffice. (__typeof *is* supported for C++, it's
__builtin_choose_expr and __builtin_types_compatible_p that aren't.)
(c) Use some suitable C++ magic in place of __builtin_types_compatible_p
(remembering that __builtin_types_compatible_p explicitly removes type
qualifiers, and alternative C++ magic needs to do likewise).

commit 3d452dabd1f063bdf251825a3ba5d68461921def
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Aug 9 17:51:26 2017 +0000
Fix uc_* namespace (bug 21457).
The standard members of ucontext_t, in all standard versions with that
type, are uc_link, uc_sigmask, uc_stack and uc_mcontext.
The uc_* namespace is mostly reserved for additions to the structure.
However, in XPG4.2, it's only reserved when <ucontext.h> is included,
not when <signal.h> is included, while <signal.h> is required to
define ucontext_t (but not allowed to make visible other symbols from
<ucontext.h>). Thus, nonstandard members should avoid uc_* names.
Some already do use __uc_*, but others don't; most architectures (all
except ia64, I think) have a member uc_flags and some have additional
members beyond that.
This patch makes nonstandard members have an __ prefix unless
__USE_MISC is defined. Members whose names indicate they are solely
padding / reserved for future use are renamed unconditionally to use
the __glibc_reserved1 naming convention.
This is part of the preparation for a revised version of the
mcontext_t / sigcontext patch to be able to eliminate all 13 of the
miscellaneous XFAILs in conform/Makefile, rather than only 11 of them
as at present (at least one further fix on top of this one will be
needed for that as well).
Tested for x86_64, and with build-many-glibcs.py.

Since typeid also removes qualifiers implicitly
(http://en.cppreference.com/w/cpp/language/typeid), would something in the
lines of the following be acceptable for c++98:
if (typeid(f) == typeid(float)) isinff (f)
Likewise for the other types and for the other functions (defined through
__MATH_TG)?
For C++11, we could use is_same, but we would need to remove the qualifiers
explicitly... Something in the lines of:
if (std::is_same<std::remove_cv<typeof(f)>::type, float>::value)
This seems more complex, so I wonder if I'm missing something in the proposed
test for c++98.

No, because that involves a runtime comparison of type_info objects. We
want something (to go in a __MATH_TG macro definition for the "C++ and
distinct float128" case - and, similarly, an isinf definition for when C++
is combined with the present conditions for handling GCC < 7 with
_Float128) that's optimized away at compile time - something where the
conditionals are always folded to true or false. (And preferably not
depending on including any C++ headers from <math.h>; I don't know what
the rules are for such header inclusion in the C++ standard library.)
Maybe we need to understand further what cases are the problem. Various
macros may be used in that configure test, but most of them are using
type-generic built-in functions which work fine for C++ (given that
libstdc++ is not built with sNaNs enabled). The problem for the configure
test might only be the "__builtin_isinf_sign is broken for float128 only
before GCC 7.0." definition of isinf, which uses
__builtin_types_compatible_p. Separately, with the installed compiler,
most of the macros should be undefined in the libstdc++ headers, leaving
issignaling as the likely problem case using __MATH_TG (issubnormal is
defined using fpclassify; iszero has a separate C++ template definition,
to avoid problems with macros).
Possible solutions for isinf include:
* Do not use the special-case isinf definition with
__builtin_types_compatible_p for C++. It's possible this suffices to make
the configure test work (and exactly what the isinf macro does doesn't
matter when using an installed C++ compiler because the libstdc++ headers
undefine that macro, and the configure test doesn't use it with float128).
* Add a C++ variant of that definition, which would only be used for the
configure test but which still has the right semantics.
And for issignaling:
* Change __MATH_TG to have a fully functional C++ variant. float and
double can be distinguished with sizeof; it's only long double / float128
where you need a replacement for __builtin_types_compatible_p (__typeof
(TG_ARG), long double) using C++ features.
* Add template versions of issignaling for C++, like iszero.

sys/ptrace.h: remove obsolete Linux PTRACE_SEIZE_DEVEL constant [BZ #21928]
Remove enum __ptrace_flags along with the only constant it contains,
PTRACE_SEIZE_DEVEL, from Linux's sys/ptrace.h files.
This temporary development constant shouldn't have been added to
sys/ptrace.h in the first place. It was introduced in Linux by commit
v3.1-rc1~308^2~28 as a temporary part of new experimental PTRACE_SEIZE
interface. Later, as PTRACE_SEIZE stabilized and lost its experimental
status, this flag was removed from Linux by commit v3.4-rc1~109^2~20.
* sysdeps/unix/sysv/linux/sys/ptrace.h (enum __ptrace_flags,
PTRACE_SEIZE_DEVEL): Remove.
* sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h: Likewise.
* sysdeps/unix/sysv/linux/ia64/sys/ptrace.h: Likewise.
* sysdeps/unix/sysv/linux/powerpc/sys/ptrace.h: Likewise.
* sysdeps/unix/sysv/linux/s390/sys/ptrace.h: Likewise.
* sysdeps/unix/sysv/linux/sparc/sys/ptrace.h: Likewise.

Fix stdlib/tst-strfmon_l.c test case to agree with the changes in Indian
monetary formatting
The test cases should expose non-standard grouping and the trailing
space after the currency sign. After the changes to the Indian
monetary formatting, the Indian formatting still shows the
non-standard grouping. To test the trailing space after the currency
sign I chose the hr_HR locale.

commit bd80111ed9cb93b2d56720dcd1d1f259616c27ae
Author: Mike FABIAN <mfabian@redhat.com>
Date: Thu Aug 10 12:16:29 2017 +0200
Fix stdlib/tst-strfmon_l.c test case to agree with the changes in Indian
monetary formatting
The test cases should expose non-standard grouping and the trailing
space after the currency sign. After the changes to the Indian
monetary formatting, the Indian formatting still shows the
non-standard grouping. To test the trailing space after the currency
sign I chose the hr_HR locale.
See:

Would you please attach preprocessed sources for the test, and also specify the
exact compiler/linker invocation.
I have not seen this reported before, so it might be something specific to your
environment.

--- Comment #2 from Felix von Leitner <felix-glibc at fefe dot de> ---
My understanding is that this is a fairly well-known problem. I found various
bug reports about it, that's why I did not report it earlier.
See for example
http://www.eglibc.org/archives/issues/msg00086.html
https://sourceware.org/bugzilla/show_bug.cgi?id=11694
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=584607

Here is what happens when I try to compile gcc from svn:
Revision: 250991
configure --prefix=/opt/gcc --sysconfdir=/etc --enable-__cxa_atexit
--libdir=/opt/gcc/lib64 --disable-bootstrap --enable-lto --enable-languages=c

void fnord () __attribute__((visibility("default")));
#endif
void fnord () { int i=42; }
int main ()
{
void *self = dlopen (0, LT_DLGLOBAL|LT_DLLAZY_OR_NOW);
int status = 0;
if (self)
{
if (dlsym (self,"fnord")) status = 1;
else
{
if (dlsym( self,"_fnord")) status = 2;
else puts (dlerror ());
}
/* dlclose (self); */
}
else
puts (dlerror ());
return status;
}
It is compiled like this:
/tmp/gcc-build/./gcc/xgcc -B/tmp/gcc-build/./gcc/
-B/opt/gcc/x86_64-pc-linux-gnu/bin/ -B/opt/gcc/x86_64-pc-linux-gnu/lib/

/opt/gcc/x86_64-pc-linux-gnu/sys-include -m32 -o conftest -g -pipe -O2
-DHAVE_DLFCN_H -Wl,--export-dynamic -static conftest.c -ldl
My first idea was that this was probably because of some files under /opt/gcc
that should not have been there, but it also fails with the regular system gcc
7.1:
% gcc -m32 -static -o conftest conftest.i -ldl
/tmp/ccvEWcVy.o: In function `main':
conftest.c:(.text+0x2c): warning: Using 'dlopen' in statically linked
applications requires at runtime the shared libraries from the glibc version
used for linking
% ./conftest
[hangs]
Bizarre. I'll attach the conftest.i, but I don't think it will help much.

What about the translations? On Fedora 26, most translations at the moment
are in
/usr/share/locale/zh_TW/
and very few are in /usr/share/locale/cmn/
I also wonder why only the "cmn" exists and not "cmn_TW" and "cmn_CN",
probably one would need to make a distinction between traditional and
simplified
here as well. As there is no cmn_CN locale, this does not matter at the
moment but it might matter in future ...
Users of zh_TW and cmn_TW would probably want the same translations, so maybe
one of these folders should be a symlink to the other?

I can't reproduce this with glibc 2.26 and GCC 7.1. Could you please attach
the executable (compiled with -g) and a matching coredump (perhaps generated
with gcore) to this bug? Thanks.

--- Comment #6 from Florian Weimer <fweimer at redhat dot com> ---
Thanks. The binary is incorrectly linked.
_dl_dst_count calls strchr:
Dump of assembler code for function _dl_dst_count:
…
0x080729bb <+123>: call 0x805c6e0 <strchr>
But strchr is not an implementation of strchr, but the IFUNC resolver for
strchr:
Dump of assembler code for function strchr:
0x0805c6e0 <+0>: lea 0x805c710,%eax
0x0805c6e6 <+6>: testl $0x4000000,0x80d7574
0x0805c6f0 <+16>: je 0x805c70a <strchr+42>
0x0805c6f2 <+18>: lea 0x8069750,%eax
0x0805c6f8 <+24>: testl $0x4,0x80d75a0
0x0805c702 <+34>: je 0x805c70a <strchr+42>
0x0805c704 <+36>: lea 0x8069370,%eax
0x0805c70a <+42>: ret
(gdb) info symb 0x805c710
__strchr_ia32 in section .text of t
This could be a binutils bug, or another toolchain issue. We don't see it with
our binutils 2.29 builds, and we have IFUNCs enabled in GCC.
For strchr.o from Fedora 27's libc.a, I get this:
$ readelf -W -a strchr.o | grep IFUNC
6: 00000000 43 IFUNC GLOBAL DEFAULT 1 strchr
So the function is correctly marked as an IFUNC resolver. dl-load.o contains a
direct call to strchr. ld then generates a PLT stub for strchr which jumps to
the function pointer previously initialized with the result of the IFUNC
resolver.
In your binary, the PLT stub is missing, and there is a direct call to the
IFUNC resolver instead, which is obviously wrong. This could be an issue
present in libc.a already, or it could be an ld bug which manifests only during
the final static link.

Bug ID: 21941
Summary: powerpc: Wrong register constraint for xssqrtqp in
sqrtf128
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: gftg at linux dot vnet.ibm.com
Target Milestone: ---
The instruction xssqrtqp, from POWER ISA 3.0, requires that the operands be in
Vetor Registers (Altivec/VMX). However, the POWER9 version of sqrtf128 uses the
"wq" register constraint, which allows GCC to put the operands in Vector-Scalar
Registers (VSX).

commit 4d98ace9de3183309cb394cd0110eda5ad2d2531
Author: Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
Date: Mon Aug 7 09:14:14 2017 -0300
powerpc: Restrict xssqrtqp operands to Vector Registers (bug 21941)
POWER ISA 3.0 introduces the xssqrtqp instructions, which expects
operands to be in Vector Registers (Altivec/VMX), even though this
instruction belongs to the Vector-Scalar Instruction Set.
In GCC's Extended Assembly for POWER, the 'wq' register constraint is
provided for use with IEEE 754 128-bit floating-point values. However,
this constraint does not limit the register allocation to Vector
Registers (Altivec/VMX) and could assign a Vector-Scalar Register (VSX)
to the operands of the instruction.
This patch changes the register constraint used in sqrtf128 from 'wq' to
'v', in order to request a Vector Register (Altivec/VMX) for use with
the xssqrtqp instruction.
Tested for powerpc64le and --with-cpu=power9.
[BZ #21941]
* sysdeps/powerpc/fpu/math_private.h (__ieee754_sqrtf128): Since
xssqrtqp requires operands to be in Vector Registers
(Altivec/VMX), replace the register constraint 'wq' with 'v'.
* sysdeps/powerpc/powerpc64le/power9/fpu/e_sqrtf128.c
(__ieee754_sqrtf128): Likewise.

Why the hell would the IFUNC stuff be in the statically linked libc in the

Which one is correct, or both? Arabic as a macro-language may have the same

--- Comment #8 from Florian Weimer <fweimer at redhat dot com> ---
(In reply to Felix von Leitner from comment #7)
> $ nm /usr/lib/libc.a 2>&1 | grep -w strchr
> strchr.o:
> 00000000 T strchr
This is a bit suspicious. It should show something like this, to mark the
symbol as an IFUNC resolver:
00000000 i strchr
What does “readelf -W -s†report for this symbol?
Can you attach the strchr.o object file?
> Disassembly of section .text:
>
> 00000000 <strchr>:
> 0: 8d 05 00 00 00 00 lea 0x0,%eax
> 2: R_386_32 __strchr_ia32
That's not unusual per se because objdump has some trouble to interpret the
IFUNC resolver symbol information. I get the same output for a properly
compiled strchr.o file.
> Why the hell would the IFUNC stuff be in the statically linked libc in the

IFUNC resolvers are used in statically linked binaries as well. The startup
code performs minimal relocation to set this up (look for apply_irel in the
dynamic linker sources).
> My gcc 7.1 binary is even older than my binutils and glibc builds.
What does “gcc -v†show? Was it compiled with --enable-gnu-indirect-function?

Bug ID: 21942
Summary: _dl_dst_substitute incorrectly handles $ORIGIN: with
AT_SECURE=1
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
With an RPATH entry "$ORIGIN:./", _dl_dst_substitute checks the wrong path for
trustworthiness, resulting in an incorrect library search path.
I patched logging into elf/dl-load.c and set __libc_enable_secure
unconditionally, and got this:
12051: _dl_dst_substitute: looking at: $ORIGIN:./
12051: is_dst: $ORIGIN:./ found
12051: _dl_dst_substitute: $ substitution: /root/origin/.
12051: _dl_dst_substitute: remaining string: :./
12051: _dl_dst_substitute: looking at: :./
12051: _dl_dst_substitute: looking at: ./
12051: _dl_dst_substitute: looking at: /
12051: is_trusted_path_normalize: path start: [[/root/origin/.:./]]
(17)
12051: is_trusted_path_normalize: path transformed:
[[/root/origin/.:./]]
12051: is_trusted_path_normalize: npath: [[/root/origin/.:./]]
12051: is_trusted_path_normalize: path is NOT trusted
12051: final path element is not trusted: /root/origin/.:./
12051: _dl_dst_substitute result:
The log indicates that dl_dst_substitute performs $ORIGIN expansion, but the
check for the trustworthiness of the expanded component does not stop at the
next ':' character. Instead is_trusted_path_normalize is called with a
substring which includes the next path element as well. The cause for that we
do not look at name[0] to recognize the ':', only name[1]:
else
{
*wp++ = *name++;
if (is_path && *name == ':')
I'm not sure if there is a trivial fix for this. The execution flow is very
complicated.

Target Milestone: ---
XPG4.2 defines the siginfo_t type, but not union sigval or its contents,
resulting in namespace violations for sigval, sival_int and sival_ptr for
signal.h and sys/wait.h for that standard because those headers incorrectly
expose those names in that case.

i386: Add _dl_runtime_resolve_shstk/_dl_runtime_profile_shstk [BZ #21598]
Add SHSTK compatible symbol resolvers to support Shadow Stack in Intel
Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
Replace _dl_runtime_resolve and _dl_runtime_profile with
_dl_runtime_resolve_shstk and _dl_runtime_profile_shstk, respectively if
SHSTK is enabled.
[BZ #21598]
* sysdeps/i386/dl-trampoline.S (_dl_runtime_resolve_shstk): New.
(_dl_runtime_profile_shstk): Likewise.
* sysdeps/unix/sysv/linux/i386/dl-cet.c: New file.

commit 042f0cdda83c0057ebb43ccd3c264f7bdc738694
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Thu Jun 22 04:15:39 2017 -0700
x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.
* config.h.in (ENABLE_CET): New #undef.
* configure.ac: Add --enable-cet.

* elf/dl-load.c (filebuf): Moved before "dynamic-link.h".

Add private_function for private functions within glibc [BZ #21598]
USE_REGPARMS in config.h.in is only used to control how parameters are
passed for internal functions on i386. On i386, we define
#define internal_function __attribute__ ((regparm (3), stdcall))
so that we pass up to 3 integer parameters in registers for internal
functuons on i386. i386 has
_dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
which is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding when shadow
stack is enabled. However, internal_function, which should be used only
with hidden function within libc.so, are also used with private function
calls between different shared objects of glibc.
This patch removes USE_REGPARMS and internal_function from config.h.in.
It adds a new header file, function-attrs.h, to define internal_function
and private_function, which is for private function calls between
different shared objects. Currently, sysdeps/i386/function-attrs.h
defines private_function as
#define private_function __attribute__ ((regparm (3), stdcall))
There is no change in shared objects on Linux/i686 nor Linux/x86_64.
When shadow stack is enabled, private_function will be defined as
#define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used as scratch register by _dl_runtime_resolve.

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding when shadow
stack is enabled. However, internal_function, which should be used only
with hidden function within libc.so, are also used with private function
calls between different shared objects of glibc.
This patch removes USE_REGPARMS and internal_function from config.h.in.
It adds a new header file, function-attrs.h, to define internal_function
and private_function, which is for private function calls between
different shared objects. Currently, sysdeps/i386/function-attrs.h
defines private_function as
#define private_function __attribute__ ((regparm (3), stdcall))
There is no change in shared objects on Linux/i686 nor Linux/x86_64.
When shadow stack is enabled, private_function will be defined as
#define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used as scratch register by _dl_runtime_resolve.

commit 70a6707fa15e63591d991761be025e26e8d02bb6
Author: Stanislav Brabec <sbrabec@suse.cz>
Date: Wed Nov 2 16:52:58 2016 +0100
Locales: Use Unicode wise thousands separator
Many languages use small gap as thousands separator.
Thousands separator should not be a plain space, but a narrow space.
And additionally, it is not allowed to wrap line in the middle of the
number.
Locale data were created in a deep age of 8-bit encodings, so most of
them use space (incorrect: it allows wrapping the line in the middle
of the number), or NBSP (better, but typographically incorrect: space
between groups is too wide).
Now UNICODE is widely supported, so we should leave legacy characters
in favor of correct UNICODE character.
UNICODE has a dedicated character for this purpose:
NNBSP
U+202F NARROW NO-BREAK SPACE: a narrow form of a no-break space,
typically the width of a thin space or a mid space
The NNBSP exists since Unicode 3.0.
Use of NNBSP will prevent line wrapping in the midle of number and
improve readability of numbers.

separator.

Add private_function for private functions within glibc [BZ #21598]
USE_REGPARMS in config.h.in is only used to control how parameters are
passed for internal functions on i386. On i386, we define
#define internal_function __attribute__ ((regparm (3), stdcall))
so that we pass up to 3 integer parameters in registers for internal
functuons on i386. i386 has
_dl_runtime_resolve:
movl (%esp), %ecx
movl %eax, (%esp) # Store the function address.
movl 4(%esp), %eax
ret $12 # Jump to function address.
which is incompatible with Shadow Stack in Intel Control-flow Enforcement
Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
since shadow stack doesn't match return stack. We need to use register
indirect branch via %ecx. That means only 2 parameters can be passed
in registers for external function calls with lazy binding when shadow
stack is enabled. However, internal_function, which should be used only
with hidden function within libc.so, are also used with private function
calls between different shared objects of glibc.
This patch removes USE_REGPARMS and internal_function from config.h.in.
It adds a new header file, function-attrs.h, to define internal_function
and private_function, which is for private function calls between
different shared objects. Currently, sysdeps/i386/function-attrs.h
defines private_function as
#define private_function __attribute__ ((regparm (3), stdcall))
There is no change in shared objects on Linux/i686 nor Linux/x86_64.
When shadow stack is enabled, private_function will be defined as
#define private_function __attribute__ ((regparm (2), stdcall))
so that %ecx can be used as scratch register by _dl_runtime_resolve.

non-lib modules should not be compiled with -DMODULE_NAME=libc.
This patch put these non-lib modules in $(others-extras) and add
$(others-extras) to all-nonlib.

ar_EG:
name_fmt "%p%t%f%t/
%g"
ar_SA:
name_fmt "%d%t%g%t/
%m%t%f"
I have no idea which one is correct.

Yes, that’s why I asked where Akhilesh got this from.
Akhilesh’s patch sets the contents of LC_NAME identical
for all Arabic locales. But I have now idea whether
Ms -> الآنسة
Miss-> يغيب
Mr -> السيد
Mrs -> السيدة
is valid for all Arabic dialects. Possibly not,
there maybe differences. So I would like some better proof
that this is really the same for all Arabic locales
than just

Yes, can you please also report this to that language team?
I tried to report this but my mail bounced because I am
not subscribed to that mailing list.
I had the last translator
Last-Translator: Yan Kerb <y.kerb@laposte.net>
in the CC:, so maybe he reports it ...

CLDR has
<symbols numberSystem="latn">
<decimal>,</decimal>
<group>.</group>
both for es.xml and eu.xml, so CLDR agrees with you.

Don't compile non-lib modules as lib modules [BZ #21864]
Some programs have more than one source files. These non-lib modules
should not be compiled with -DMODULE_NAME=libc. This patch puts these
non-lib modules in $(others-extras) and adds $(others-extras) to
all-nonlib.
[BZ #21864]
* Makerules (all-nonlib): Add $(others-extras).
* catgets/Makefile (others-extras): New.
* elf/Makefile (others-extras): Likewise.

seem to be either two letter abbreviations like "Mo"
or possibly with a dot like "Mo.", but never the three
letter abbreviations like "Mon".

NSS: Replace exported NSS lookup functions with stubs [BZ #21962]
Commit 384ca551743318bd9c9e24a496d6397f2e3f2a49 from 2007 added this to
nss/XXX-lookup.c:
+#ifndef NO_COMPAT
+int
+internal_function attribute_compat_text_section
+DB_COMPAT_FCT (service_user **ni, const char *fct_name, void **fctp)
+{
+ return DB_LOOKUP_FCT (ni, fct_name, NULL, fctp);
+}
+#endif
That is, it adds a pseudo-compat function with an internal_function
attribute. The function it was supposed to replace did not have the
attribute:
extern int DB_LOOKUP_FCT (service_user **ni, const char *fct_name,
- void **fctp) internal_function;
+ const char *fct2_name, void **fctp)
+ internal_function;
This changed the calling convention on i386 for the following
functions in the public ABI:
__nss_passwd_lookup
__nss_group_lookup
__nss_hosts_lookup
This commit replaces the functions with always-failing stubs,
with true compat symbols. Due to a happy accident, the calling
convention of the stub is identical for the internal_function
and non-internal_function case on i386.
In addition, this commit auto-generates the __nss_*_lookup2
function declarations as part of <nsswitch.h>.

commit 0f20efcd39a1864d01f0a3bb2aa3dfc75768f32d
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Sat Jul 29 21:04:09 2017 -0700
Don't compile non-lib modules as lib modules [BZ #21864]
Some programs have more than one source files. These non-lib modules
should not be compiled with -DMODULE_NAME=libc. This patch puts these
non-lib modules in $(others-extras) and adds $(others-extras) to
all-nonlib.
[BZ #21864]
* Makerules (all-nonlib): Add $(others-extras).
* catgets/Makefile (others-extras): New.
* elf/Makefile (others-extras): Likewise.
* nss/Makefile (others-extras): Likewise.

Use “copy "i18n"†in km_KH locale
The custom stuff which was in LC_CTYPE of the km_KH locale seems
to be a very incomplete subset of what one gets by using
“copy "i18n"â€. I cannot find anything special there which is not
in “copy "i18n"â€, only lots of stuff which is missing.
[BZ #20008]
* locales/km_KH (LC_CTYPE): Use “copy "i18n"â€.

--- Comment #3 from Mike FABIAN <maiku.fabian at gmail dot com> ---
The custom stuff which was in LC_CTYPE of the km_KH locale seems
to be a very incomplete subset of what one gets by using
“copy "i18n"â€. I cannot find anything special there which is not
in “copy "i18n"â€, only lots of stuff which is missing.
So I changed it to use “copy "i18n"â€.

x86: Support IBT and SHSTK from Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a compiler which defines defines __IBT__ and
__SHSTK__, CET is enabled, unless --disable-cet is used to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property if __IBT__ or __SHSTK__ is defined.

i386: Add _dl_runtime_resolve_shstk/_dl_runtime_profile_shstk [BZ #21598]
Add SHSTK compatible symbol resolvers to support Shadow Stack in Intel
Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
Replace _dl_runtime_resolve and _dl_runtime_profile with
_dl_runtime_resolve_shstk and _dl_runtime_profile_shstk, respectively if
SHSTK is enabled.
[BZ #21598]
* sysdeps/i386/dl-trampoline.S (_dl_runtime_resolve_shstk): New.
(_dl_runtime_profile_shstk): Likewise.
* sysdeps/unix/sysv/linux/i386/dl-cet.c: New file.

x86: Support IBT and SHSTK in Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a CET-enabled compiler, CET is enabled by
default, unless --disable-cet is used to configure glibc. When CET is
enabled, both compiler and assembler must support CET. Otherwise, it
is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property.

Yes, ',' seems correct there.

I don’t see this, I see only “₽†in that Wikipedia page,
without a dot at the end.

i386: Add _dl_runtime_resolve_shstk/_dl_runtime_profile_shstk [BZ #21598]
Add SHSTK compatible symbol resolvers to support Shadow Stack in Intel
Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
Replace _dl_runtime_resolve and _dl_runtime_profile with
_dl_runtime_resolve_shstk and _dl_runtime_profile_shstk, respectively if
SHSTK is enabled.
[BZ #21598]

commit 6a1105e6cbe82350dd0ae928a0033650eaa8aebe

x86: Support IBT and SHSTK in Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a CET-enabled compiler, CET is enabled by
default, unless --disable-cet is used to configure glibc. When CET is
enabled, both compiler and assembler must support CET. Otherwise, it
is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property.
* config.h.in (ENABLE_CET): New #undef.

x86-64: Put L(SP_RANGE)/L(SP_INF_0) in .rodata.cst4 section [BZ #21955]

lea L(SP_RANGE)(%rip), %rdx /* load over/underflow bound */
cmpl (%rdx,%rax,4), %ecx /* |x|<under/overflow bound ? */

.long 0x7f800000 /* single precision Inf */
.long 0 /* single precision zero */
.type L(SP_INF_0), @object
ASM_SIZE_DIRECTIVE(L(SP_INF_0))
Since L(SP_RANGE) and L(SP_INF_0) are accessed as arrays of 4-byte
elements, they should be placed in .rodata.cst4 section.
[BZ #21955]
* sysdeps/x86_64/fpu/e_expf.S (L(SP_RANGE)): Place it in
.rodata.cst4 section.
(L(SP_INF_0)): Likewise.

Since L(SP_RANGE) and L(SP_INF_0) are in .rodata.cst8 section, they must
be aligned to 8 bytes.
[BZ #21955]
* sysdeps/x86_64/fpu/e_expf.S (L(SP_RANGE)): Aligned to 8 bytes.
(L(SP_INF_0)): Likewise.

Bug ID: 21956
Summary: Unbounded stack allocation in pthread_rwlock_rdlock
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: aurelien at aurel32 dot net
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Host: mipsel-unknown-linux-gnu
Target: mipsel-unknown-linux-gnu
Build: mipsel-unknown-linux-gnu
Since commit cc25c8b4c1 ("New pthread rwlock that is more scalable.") the futex
syscall is used in a loop. It takes 6th arguments. On mips o32, the first four
are passed in registers while the last two are passed on the stack. The current
code in sysdeps/unix/sysv/linux/mips/mips32/sysdep.h uses an alloca(4) call to
force the use of a frame pointer. This allocates an unbounded amounts of stack.
This is the reason why nptl/tst-rwlock15 now fails with a segmentation fault.

--- Comment #5 from Mike FABIAN <maiku.fabian at gmail dot com> ---
Summary of the chatlog in the last comment
https://sourceware.org/bugzilla/show_bug.cgi?id=21750#c4
in English:
Thorsten and me agree that setting the width of U+3248..U+324F
to 2 because the glyphs for these characters are quadratic in
most fonts.
(I also asked on the
Unicode mailing list now whether this could be a bug in
the Unicode data:
http://www.unicode.org/mail-arch/unicode-ml/y2017-m08/0007.html
But even if it is not a bug, setting these to 2 seems to be
much better for users of terminals and that is what wcwidth
in glibc is mostly used for after all).
We also agree to set the width of the hexagrams U+4DC0..U+4DFF is
considerably wider than single width in most fonts. In some
classic Xorg fonts they are fully double width. In most scalable fonts
they are somewhat narrower than double width but considerabely wider
then single width. So marking them as width 1 would cause
problems in terminals, even if they are not fully double width
it makes sense to mark them as width 2 because they certainly
won’t fit in a single character cell in a terminal.
We also agree that the Hangul Jamo U+1160‥U+11FF are sort
of "combining characters" although they are not marked as such
in the Unicode data. But they are fragments of Hangul characters
which combine. So it seems correct to mark them as width 0.

--- Comment #6 from Mike FABIAN <maiku.fabian at gmail dot com> ---
And we also agree that setting the width of the soft hyphen U+00AD
to 0 as in Unicode seems to be not helpful for terminal
applications and as wcwidth is mostly important for terminal
applications, it makes sense to keep set the width of U+00AD to
1 as it "historically" always was in wcwidth.

Guys,
With a huge thanks and great respect towards you working on addressing these
issues, allow me please firmly oppose against deviating from the Unicode
database.
The width is probably indeed primarly used by terminal emulators and apps
running inside. They, however, use all kinds of various sources for this data,
not just glibc's wcwidth().
For example, VTE-based emulators (such as GNOME Terminal) rely on glib's
g_unichar_iswide(), see [1]. Alas I don't have any usage metrics, but the poll
at [2] suggest that VTE's usage share amongst terminal emulators on Linux might
be somewhere in the ballpark of 50%.
As for apps, if my memories are correct, I believe Vim uses its own built-in
database rather than wcwidth(). So does the Joe text editor [3] (okay, it's a
really marginal one), and presumably many more apps.
Let alone all other non-glibc based systems with their own wcwidth()
implementation that one might ssh to/from.
For apps inside terminal emulators to work correctly, it's crucial that all the
relevant components agree on the width. This has caused quite a headache when
Unicode 9.0 changed the width of plenty of codepoints, see e.g. the bugreport
with animgif at [4] (and tons of duplicates in other bugzillas and
stackoverflow forums), but this is going to fade away as eventually everyone's
upgrading their Unicode version.
You cannot, however, reasonably assume that other folks out there, i.e.
terminal emulators as well as applications that don't rely on wcwidth() but
some other data source, or those other data sources such as glib and probably a
whole lot more, are all going to apply your modifications. And then again we
haven't talked about ssh'ing to/from non-glibc systems.
If a certain glyph does not fit in its designated character cell, most terminal
emulators will overflow it to the next cell. A slight overflow happens at way
more codepoints than the ones debated now, e.g. in case of VTE and a not too
large font, even the antialiasing of English letters such as 'W', 'm' overflows
to the next cell. Of course I understand that the overflow in case of U+3248
"㉈" and friends is way more prominent, potentially causing the given and the
subsequent glyph not to be readable at all, which is indeed bad.
But causing the entire canvas's contents to fall apart is even worse. And
that's what typically happens when players of the game disagree on the width,
as seen e.g. again at [4].
If you'd really like to see these particular codepoints becoming double wide
(which I'm also in favor of), I firmly believe this change should be made in
the Unicode database first, so that eventually everyone implementing a
wcwidth()-like method gets that update; rather than just glibc, resulting in a
long-term disagreement between parties and in turn inevitable corruption of the
entire terminal window in quite a few terminal emulators and apps.

Since commit cc25c8b4c1 ("New pthread rwlock that is more scalable.") the futex
syscall is used in a loop. It takes 6th arguments. On mips o32, the first four
are passed in registers while the last two are passed on the stack. The current
code in sysdeps/unix/sysv/linux/mips/mips32/sysdep.h uses an alloca(4) call to
force the use of a frame pointer. This allocates an unbounded amounts of stack.
This is the reason why nptl/tst-rwlock15 now fails with a segmentation fault.

This is a defect in the MIPS32 sysdep.h code. There are lots of places where we
can make syscalls in a loop and have unbounded stack allocation. This machine
code needs to be adjusted to fix this.
I'm CC'ing the machine maintainer.

--- Comment #2 from Carlos O'Donell <carlos at redhat dot com> ---
Setting security- because the stack allocation is very small, and bounded, and
we have no known way to trigger this in any real applications. The
nptl/tst-rwlock15 test is a very synthetic test with almost a zero sized rdlock
section.

--- Comment #8 from Thorsten Glaser <tg at mirbsd dot de> ---
Hi Egmont,
only a short response because we have FrOSCon/FrogLabs preparations and
workshop until Monday:
We’re not strictly speaking deviating from UCD because UCD does *not* define
wcwidth.
Terminal emulators use wcwidth, especially xterm uses ONLY it *and* defines it.
Applications such as editors in the terminal (cf. jupp) use wcwidth or carry
their own data which is prepared the same way as wcwidth (often they use a copy
of xterm's code).
You speak of compatibility and breaking. Strictly speaking, the switch glibc
recently (two or three majors, I think) did to regenerated data *did* break
applications, and this bugreport is 100% returning the glibc data to the way it
was before in the places the previous change introduced bugs, while still
keeping it up-to-date with recent Unicode.
So, therefore, with this patch applied, less things will break than without.
Outlyers like libglib (used by only one of the multitude of terminal emulators)
can then import the data (and mechanism used to generate) from here.
Other systems use the old wcwidth code from xterm, to which this one (with my
patches applied) is compatible for all chars that did not get changed in or
added to Unicode, which is the maximum compatibility and an easily to achieved,
and achievable and should-be-achieved goal.

commit 67f0aff0c63e5deaade7f6cc7758f5cb63344fb8
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Aug 16 20:33:59 2017 +0000
Fix sigval namespace (bug 21944).
XPG4.2 defines the siginfo_t type, but not union sigval or its
contents (which were added in the 1993 edition of POSIX.1), resulting
in namespace violations for sigval, sival_int and sival_ptr for
signal.h and sys/wait.h for that standard because those headers
incorrectly expose those names in that case.
This patch fixes this problem. The public type in this case is union
sigval, but various places in the headers use the sigval_t name for
it; direct uses of union sigval are already properly guarded or in
headers not in XPG4.2. Now, sigval_t, although not a standard name,
does seem to be widely used outside glibc. The approach taken by this
patch is to make installed headers use the name __sigval_t instead.
__sigval_t is then defined to either union sigval or union __sigval
(where union __sigval has __-prefixed member names as well), depending
on whether there are any namespace issues with the union sigval name
and its members. In the case where union __sigval is used, sigval_t
is not defined at all, to avoid the problem of sigval_t having a C++
mangled name that depends on feature test macros. sigval_t is still
defined by signal.h if __USE_MISC (reflecting the nonstandard nature
of that name).
Tested for x86_64.
[BZ #21944]
* signal/bits/types/__sigval_t.h: New file.
* signal/Makefile (headers): Add bits/types/__sigval_t.h.
* signal/bits/types/sigval_t.h: Include <bits/types/__sigval_t.h>
and define sigval_t using __sigval_t.
* include/bits/types/__sigval_t.h: New file.
* bits/types/sigevent_t.h: Include <bits/types/__sigval_t.h>
instead of <bits/types/__sigval_t.h>.
(struct sigevent): Use __sigval_t instead of sigval_t.
* bits/types/siginfo_t.h: Include <bits/types/__sigval_t.h>

--- Comment #25 from Horst Schirmeier <horst at schirmeier dot com> ---
This bug is still reproducible in 2.23(-r4, Gentoo) and 2.24(-9ubuntu2.2,
Ubuntu 17.04).
What I really don't get is that it even crashes if I protect calls to
gethostbyname() with a pthread mutex. However, if I call gethostbyname()
alternatingly in two different threads (2s delay between each call, one thread
1s behind the other), I could not observe crashes.
Either way, the link-time
warning: Using 'getaddrinfo' in statically linked applications requires at
runtime the shared libraries from the glibc version used for linking
should be severely upgraded to something like the following until this bug is
fixed:
warning: Using 'getaddrinfo' in statically linked applications requires at
runtime the shared libraries from the glibc version used for linking, and may
fail in spectacular ways in combination with pthreads when not yet fully
understood additional conditions hold

Disregard that. On Debian 9 with glibc 2.24 I don't need multithreading at all
to crash:

"#include <netdb.h>\nint main(void) { gethostbyname(\"foo\"); }" > foo.c && \
gcc -g -static foo.c && ./a.out
/tmp/ccxQLvv6.o: In function `main':

I guess that warrants a separate bug report?

Target: x86-64
AVX2 mathvec functions, like svml_s_sinf8_core_avx2.S, use FMA:
vfnmadd231ps %ymm2, %ymm1, %ymm0
But mathvec IFUNC selectors only check AVX2, not FMA. These functions
will fail on machines with AVX2, but without FMA.

Version: 2.27

Target Milestone: ---
Target: x86-64
521-bit AVX2 wrapper functions in mathvec, likesvml_d_log8_core-avx2.S, have
#define _ZGVeN8v_log _ZGVeN8v_log_avx2_wrapper
#include "../svml_d_log8_core.S"
It is used by svml_d_log8_core.c with
static inline void *
IFUNC_SELECTOR (void)
{
const struct cpu_features* cpu_features = __get_cpu_features ();
if (CPU_FEATURES_ARCH_P (cpu_features, AVX512DQ_Usable))
return OPTIMIZE (skx);
if (CPU_FEATURES_ARCH_P (cpu_features, AVX512F_Usable))
return OPTIMIZE (knl);
return OPTIMIZE (avx2_wrapper);
}
So if AVX512 isn't available, _ZGVeN8v_log_avx2_wrapper will be used. It
is compiled into
0000000000000000 <_ZGVeN8v_log_avx2_wrapper>:
0: 55 push %rbp
1: 48 89 e5 mov %rsp,%rbp
4: 48 83 e4 c0 and $0xffffffffffffffc0,%rsp
8: 48 81 ec 80 00 00 00 sub $0x80,%rsp
f: 62 f1 7c 48 11 04 24 vmovups %zmm0,(%rsp)
16: c5 fd 10 04 24 vmovupd (%rsp),%ymm0
1b: e8 00 00 00 00 callq 20 <_ZGVeN8v_log_avx2_wrapper+0x20>
1c: R_X86_64_PC32 __GI__ZGVdN4v_log-0x4
20: c5 fd 11 44 24 40 vmovupd %ymm0,0x40(%rsp)
26: c5 fd 10 44 24 20 vmovupd 0x20(%rsp),%ymm0
2c: e8 00 00 00 00 callq 31 <_ZGVeN8v_log_avx2_wrapper+0x31>
2d: R_X86_64_PC32 __GI__ZGVdN4v_log-0x4
31: c5 fd 11 44 24 60 vmovupd %ymm0,0x60(%rsp)
37: 62 f1 7c 48 10 44 24 01 vmovups 0x40(%rsp),%zmm0
3f: 48 89 ec mov %rbp,%rsp
42: 5d pop %rbp
43: c3 retq
But
f: 62 f1 7c 48 11 04 24 vmovups %zmm0,(%rsp)
is an AVX512F instruction. How is it supposed to work?

--- Comment #12 from Egmont Koblinger <egmont at gmail dot com> ---
(In reply to Thorsten Glaser from comment #8)

Well, it defines the East_Asian_Width property from which you derive wcwidth
using a couple of generic rules plus a few exceptions to them.
You've just (re?)added 3248..324F and a few other ranges to these exceptions,
which in my eyes means that yes, you are deviating from Unicode.

To be more precise, xterm and a few others copy Markus Kuhn's implementation. I
don't think anyone copies from xterm.
This defines the 3248..324F range as ambiguous (I've checked the most recent
xterm-330 and a randomly chosen ~4 year old xterm-300 – a randomly picked even
older xterm-260 is different which suggests that case xterm has a long ago
caught up with the changes), which, by default, means it is 1 cell wide in
xterm (unless -cjk_width is specified in which case all other ambiguous ones
are turned into double)...

... so I absolutely don't get why less things would be broken now. As far as I
can see, with this patch you have just further broken the handling of these
codepoints by deviating from Unicode and from xterm.

You really don't seriously expect that two glibc maintainers decide over a chat
that they add a few exceptions to the generic rules, and "outlyers" (like glib,
maybe Qt, maybe Java, maybe some other "giant" pieces of (perhaps commercial)
software, maybe other libc implementations of other Unices (like Mac), maybe a
whole lot more) will follow; do you??
(And on a side note... IMHO submitting a change right after someone brings up
some concerns, not even giving time for a reasonable discussion, isn't really a
polite thing... Especially since recently it took me about 2 years and about
10-15 pings that were left unanswered to get through a well unittested locale
change, I can't understand why this hurry now.)

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

powerpc: Restrict xssqrtqp operands to Vector Registers (bug 21941)
POWER ISA 3.0 introduces the xssqrtqp instructions, which expects
operands to be in Vector Registers (Altivec/VMX), even though this
instruction belongs to the Vector-Scalar Instruction Set.
In GCC's Extended Assembly for POWER, the 'wq' register constraint is
provided for use with IEEE 754 128-bit floating-point values. However,
this constraint does not limit the register allocation to Vector
Registers (Altivec/VMX) and could assign a Vector-Scalar Register (VSX)
to the operands of the instruction.
This patch changes the register constraint used in sqrtf128 from 'wq' to
'v', in order to request a Vector Register (Altivec/VMX) for use with
the xssqrtqp instruction.
Tested for powerpc64le and --with-cpu=power9.
[BZ #21941]
* sysdeps/powerpc/fpu/math_private.h (__ieee754_sqrtf128): Since
xssqrtqp requires operands to be in Vector Registers
(Altivec/VMX), replace the register constraint 'wq' with 'v'.
* sysdeps/powerpc/powerpc64le/power9/fpu/e_sqrtf128.c
(__ieee754_sqrtf128): Likewise.
(cherry picked from commit 4d98ace9de3183309cb394cd0110eda5ad2d2531)

Bug ID: 21972
Summary: assert macro requires operator== (int) for its
argument type
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
After the fix for bug 21242, the assert macro implementation requires that the
argument can be compared to 0, which breaks the following code:
#include <assert.h>
struct S {
explicit operator bool() const;
};
void f(S &s)
{
assert (s);
}
The C++ standard is inconsistent due to its C standard import, but we should
fix this as a QoI issue. Using static_cast<bool> (expr) instead is sufficient.

commit 6913ad65e00bb32417ad39c41d292b976171e27e
Author: Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
Date: Mon Aug 14 17:51:51 2017 -0300
Do not use generic selection in C++ mode
The logic to protect the use of generic selection (_Generic) does not
check for C or C++ mode, however, generic selection is a C-only
feature.
Tested for powerpc64le.
* misc/sys/cdefs.h (__HAVE_GENERIC_SELECTION): Define to 0, if
in C++ mode.

commit 47a67213a9f51c5f8816d240500b10db605d8b77
Author: Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
Date: Fri Aug 11 14:29:06 2017 -0300
Do not use __builtin_types_compatible_p in C++ mode (bug 21930)
The logic to define isinf for float128 depends on the availability of
__builtin_types_compatible_p, which is only available in C mode,
however, the conditionals do not check for C or C++ mode. This lead to
an error in libstdc++ configure, as reported by bug 21930.
This patch adds a conditional for C mode in the definition of isinf for
float128. No definition is provided in C++ mode, since libstdc++
headers undefine isinf.
Tested for powerpc64le (glibc test suite and libstdc++-v3 configure).
[BZ #21930]
* math/math.h (isinf): Check if in C or C++ mode before using
__builtin_types_compatible_p, since this is a C mode feature.

Mark internal argz functions with attribute_hidden [BZ #18822]
Move internal argz function prototypes to include/argz.h and mark them
with attribute_hidden to allow direct access within libc.so and libc.a
without using GOT nor PLT. This also brings string/argz.h closer to the
gnulib version.
[BZ #18822]
* include/argz.h (__argz_create_sep): New function prototype.
(__argz_append): Likewise.
(__argz_add): Likewise.
(__argz_add_sep): Likewise.
(__argz_delete): Likewise.
(__argz_insert): Likewise.

--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
avx2_wrapper is supposed to be used when AVX512F isn't profitable. But
with
if (CPU_FEATURES_ARCH_P (cpu_features, AVX512DQ_Usable))
return OPTIMIZE (skx);
if (CPU_FEATURES_ARCH_P (cpu_features, AVX512F_Usable))
return OPTIMIZE (knl);
it is never used. There is a Prefer_No_AVX512 bit in cpu_features. But
we don't want to use it here since it will disable AVX512 mathvec on Skylake
server. We need a separate bit to control AVX512 mathvec.

Summary: Remove __bb_init_func and __bb_exit_func
Product: glibc
Version: 2.27
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com

Target Milestone: ---
__bb_init_func and __bb_exit_func have been removed from GCC 3.3 in 2002 by
https://gcc.gnu.org/ml/gcc-patches/2002-09/msg00499.html
which also recommended that they should also be removed from glibc. These
functions exist only in libc.a and are used for backward compatibility
with older versions of GCC. Do we need to support gcov with GCC 3.2?

Bug ID: 21975
Summary: gethostbyname always segfaults if linked statically
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: horst at schirmeier dot com
Target Milestone: ---
With glibc 2.24 (reproducible on 64-bit Debian 9 or Ubuntu 17.04),
gethostbyname() always segfaults if the binary was linked statically:
$ echo -e "#include <netdb.h>\nint main(void){gethostbyname(\"foo\");}" > foo.c
&& gcc -g -static foo.c && ./a.out
/tmp/ccp8JNGC.o: In function `main':
/tmp/foo.c:2: warning: Using 'gethostbyname' in statically linked applications
requires at runtime the shared libraries from the glibc version used for
linking
Segmentation fault (core dumped)
$ gdb -c core
GNU gdb (Ubuntu 7.12.50.20170314-0ubuntu1.1) 7.12.50.20170314-git
[...]
[New LWP 28640]
Core was generated by `./a.out'.
Program terminated with signal SIGSEGV, Segmentation fault.

I cannot reproduce with 2.24 or 2.25, which is a pity because Fedora has a
static glibc with debugging symbols. It could be a Debian or Ubuntu patch.
You need to link with debugging symbols and post a backtrace with symbols at
least.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

--- Comment #3 from Horst Schirmeier <horst at schirmeier dot com> ---
To me these backtrace addresses look like the stack is smashed, i.e. debug
symbols wouldn't help. But in fact it looks like Ubuntu's libc.a does come
with debug symbols.
Interestingly, when running a.out directly in gdb instead of loading the
coredump, the backtrace makes more sense:
$ gdb a.out
GNU gdb (Ubuntu 7.12.50.20170314-0ubuntu1.1) 7.12.50.20170314-git

--- Comment #4 from Florian Weimer <fweimer at redhat dot com> ---
Is there a reason why you use systemd-resolved?
libnss_resolve probably links against libpthread (at least the systemd
components I've seen all do that), and loading that via dlopen from a
statically linked binary is problematic.
Late loading of libpthread into a statically linked program is very difficult
to get right because preparing for that invalidates a lot of optimizations one
wants to do when linking statically. For the time being, you'll just have to
use NSS modules which do not link against libpthread.

Remove __bb_init_func and __bb_exit_func [BZ #21974]
__bb_init_func and __bb_exit_func have been removed from GCC 3.3 in
2002 by
https://gcc.gnu.org/ml/gcc-patches/2002-09/msg00499.html
which also recommended that they should also be removed from glibc. These
functions exist only in libc.a and are used for gcov from versions of GCC
older than GCC 3.3.
[BZ #21974]
* gmon/Makefile (routines): Remove bb_init_func and
bb_exit_func.
(elide-routines.os): Removed.

You don't happen to know which Debian/Ubuntu packages provide such modules? :-)

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

functions exist only in libc.a and are used for gcov from versions of GCC
older than GCC 3.3.

After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.

After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Using of avx2_wrapper in avx512 ifunc is logic bug. Looks like where are no
possibility to extract hi part of zmm w/o AVX512 instuction.
Mathvec runtime tests has runtime ISA check, so those illegal instruction
wasn't catched on testing.
As I remember those wrappers were originally created for 2 use cases: Glibc
build with AS not supporting AVX512 and for Glibc build with
--disable-multi-arch.
AVX512 mathvec functions are called only if binary compiled for AVX512 ISA.
So if such a binary run on HW w/o AVX512 it will fail earlier than inside
vector function.
I think we need simply remove

Don't compile non-lib modules as lib modules [BZ #21864]
Some programs have more than one source files. These non-lib modules
should not be compiled with -DMODULE_NAME=libc. This patch puts these
non-lib modules in $(others-extras) and adds $(others-extras) to
all-nonlib.
[BZ #21864]
* Makerules (all-nonlib): Add $(others-extras).
* catgets/Makefile (others-extras): New.
* elf/Makefile (others-extras): Likewise.
* nss/Makefile (others-extras): Likewise.

commit 5e989c36934d0f0cf13b7a53ef2fa440bce39210
Author: Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
Date: Mon Aug 14 17:51:51 2017 -0300
Do not use generic selection in C++ mode
The logic to protect the use of generic selection (_Generic) does not
check for C or C++ mode, however, generic selection is a C-only
feature.
Tested for powerpc64le.
* misc/sys/cdefs.h (__HAVE_GENERIC_SELECTION): Define to 0, if
in C++ mode.
(cherry picked from commit 6913ad65e00bb32417ad39c41d292b976171e27e)

commit c2921b17a37e887b8a5ca9d84b875b9ba702b79c
Author: Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
Date: Mon Aug 21 14:23:27 2017 +0200
Do not use __builtin_types_compatible_p in C++ mode (bug 21930)
The logic to define isinf for float128 depends on the availability of
__builtin_types_compatible_p, which is only available in C mode,
however, the conditionals do not check for C or C++ mode. This lead to
an error in libstdc++ configure, as reported by bug 21930.
This patch adds a conditional for C mode in the definition of isinf for
float128. No definition is provided in C++ mode, since libstdc++
headers undefine isinf.
Tested for powerpc64le (glibc test suite and libstdc++-v3 configure).
[BZ #21930]
* math/math.h (isinf): Check if in C or C++ mode before using
__builtin_types_compatible_p, since this is a C mode feature.
(cherry picked from commit 47a67213a9f51c5f8816d240500b10db605d8b77)

Do you think AVX512 mathvec functions on SKX should be wrappers to AVX2?

x86-64: Mark internal symbols with attribute_hidden [BZ #18822]
Since __syscall_clock_gettime and __start_context are internal symbols
for Linux/x86-64, mark them with attribute_hidden.
[BZ #18822]
* sysdeps/unix/sysv/linux/x86_64/init-first.c
(__syscall_clock_gettime): Add attribute_hidden.
* sysdeps/unix/sysv/linux/x86_64/makecontext.c
(__start_context): Likewise.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

--- Comment #9 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Most of the macros, including fpclassify, should be irrelevant because
libstdc++ headers undefine the macros and replace them with function
overloads (as required by the C++ standard). The problem with iszero is
specifically that the C++ iszero definition in the C math.h is using the
macro fpclassify definition (this is before libstdc++ gets a chance to
undefine it), and, in the case (__SUPPORT_SNAN__ and float128 supported),
that definition is using __builtin_types_compatible_p. So some approach
is needed for iszero to work in that place - without conflicting with
libstdc++'s own fpclassify overloads.

--- Comment #10 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
I will add, for completeness: I don't consider the uses of
__builtin_types_compatible_p in tgmath.h for float128 to be a bug. For
C++11 and later libstdc++'s tgmath.h does not include the C library
header, and the C macros in tgmath.h rely on details of C type conversions
which don't work for C++ anyway.

--- Comment #11 from Gabriel F. T. Gomes <gftg at linux dot vnet.ibm.com> ---
For iszero, I could write a patch similar to the one I wrote (and that is still
under review) for issignaling
(https://sourceware.org/ml/libc-alpha/2017-08/msg00859.html). That would make
iszero use the correct __fpclassify* function for each type, instead of relying
on the type-generic fpclassify macro.
Does that sound like a good approach for this problem?

--- Comment #12 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
That approach to iszero seems reasonable (provided it's only for the
__SUPPORT_SNAN__ case, the case where iszero just compares with zero can
stay with the template).

commit 831bbd55271eacc0190a13954bd347f0a521b096
Author: Joseph Myers <joseph@codesourcery.com>

Remove SPARC sqrt wrappers (bug 21973).
This patch removes the SPARC-specific wrappers for sqrt and sqrtf.
These wrappers, by adding architecture-specific uses of _LIB_VERSION
and __kernel_standard, unnecessarily complicate cleanups of libm error
handling. They also do not serve a useful optimization purpose. GCC
knows about sqrt as a built-in function, and can generate direct calls
to a hardware square root instruction, either on its own, in the
-fno-math-errno case, or together with an inline check for the
argument being negative and a call to the out-of-line sqrt function
for error handling only in that case (and has been able to do so for a
long time). Thus in practice the wrapper will only be called only in
the case of negative arguments, which is not a case it is useful to
optimize for.
The removal of the wrappers also uncovers, and fixes, an old bug.
32-bit SPARC libm used (checked with glibc 2.8 binaries) to have a
sqrtl compat symbol, version GLIBC_2.0, for old binaries when sqrtl
was an alias of sqrt (I don't have pre-glibc-2.4 binaries for SPARC to
hand to check for the sqrtl symbol in those). This disappeared,
probably with:
commit 8847f0377003fbfe9cbe951ce9f8717d74f26247
Author: David S. Miller <davem@davemloft.net>
Date: Tue Feb 28 22:37:58 2012 -0800
Add sparc optimized sqrt{,f}.
Removing the wrappers brings back the generic ldbl-opt logic for
creating such compat symbols, and so restores the compat symbol that
should be there. This could of course also be fixed in the wrappers -
but as noted above, the wrappers are optimizing a case it's not useful
to optimize, so the bug of the missing compat symbol serves to
illustrate the risks involved with the extra complexity of
architecture-specific function versions where not needed.
Tested with build-many-glibcs.py.

Bug ID: 21986
Summary: __guess_grouping is called incorrectly
Product: glibc
Version: 2.27
Status: NEW
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
stdlib/strfmon_l.c has
/* If we have to print the digits grouped determine how many
extra characters this means. */
if (group && left_prec != -1)
left_prec += __guess_grouping (left_prec,
_NL_CURRENT (LC_MONETARY, MON_GROUPING),
*_NL_CURRENT (LC_MONETARY,
MON_THOUSANDS_SEP));
But __guess_grouping is defined in stdio-common/printf_fp.c as
unsigned int
__guess_grouping (unsigned int intdig_max, const char *grouping)
{
So the 3rd argument passed to __guess_grouping is ignored.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

string/stratcliff.c: Replace int with size_t [BZ #21982]
Fix GCC 7 errors when string/stratcliff.c is compiled with -O3:
stratcliff.c: In function ‘do_test’:
cc1: error: assuming signed overflow does not occur when assuming that (X -
c) <= X is always true [-Werror=strict-overflow]
[BZ #21982]
* string/stratcliff.c (do_test): Declare size, nchars, inner,
middle and outer with size_t instead of int. Repleace %d and
%Zd with %zu in printf.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Fix position of tests-unsupported definition in assert/Makefile.
tests-unsupported has to be defined before the inclusion of Rules in a
subdirectory Makefile; otherwise it is ineffective. This patch fixes
the ordering in assert/Makefile, where a recent test addition put
tests-unsupported too late (resulting in build failures when the C++
compiler was missing or broken, and thereby showing up the unrelated
bug 21987).
Incidentally, I don't see why these tests depend on
$(have-cxx-thread_local) rather than just a working C++ compiler.
Tested in such a configuration (broken compiler/libstdc++) with
build-many-glibcs.py.
* assert/Makefile [$(have-cxx-thread_local)]: Move conditional
variable definitions above inclusion of ../Rules.

My refactoring of long double information
commit 0acb8a2a855395c25b1feef2470f4d7ca4bed589
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Dec 14 18:27:56 2016 +0000
Refactor long double information into bits/long-double.h.
resulted in sparc32 configurations installing the ldbl-opt version of
bits/long-double.h instead of the intended sysdeps/unix/sysv/linux/sparc
version.
For sparc32 by itself, this is not a problem, since the ldbl-opt version is
correct for sparc32. However, both sparc32 and sparc64 are supposed to install
sets of headers that work for both of them, so that a single sysroot, whichever
order the libraries are built and installed in, works for both. The effect of
having the wrong version installed is that you end up with a miscompiled
sparc64 libstdc++ which fails glibc's configure tests for the C++ compiler.

Fix sparc32 bits/long-double.h (bug 21987).
My refactoring of long double information
commit 0acb8a2a855395c25b1feef2470f4d7ca4bed589
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Dec 14 18:27:56 2016 +0000
Refactor long double information into bits/long-double.h.
resulted in sparc32 configurations installing the ldbl-opt version of
bits/long-double.h instead of the intended
sysdeps/unix/sysv/linux/sparc version.
For sparc32 by itself, this is not a problem, since the ldbl-opt
version is correct for sparc32. However, both sparc32 and sparc64 are
supposed to install sets of headers that work for both of them, so
that a single sysroot, whichever order the libraries are built and
installed in, works for both. The effect of having the wrong version
installed is that you end up with a miscompiled sparc64 libstdc++
which fails glibc's configure tests for the C++ compiler.
This patch moves the header from sysdeps/unix/sysv/linux/sparc to
separate copies of the same file for sparc32 and sparc64, to ensure it
comes before ldbl-opt in the sysdeps directory ordering.
Tested with build-many-glibcs.py for sparc64-linux-gnu and
sparcv9-linux-gnu.
[BZ #21987]
* sysdeps/unix/sysv/linux/sparc/bits/long-double.h: Remove file
and copy to ...
* sysdeps/unix/sysv/linux/sparc/sparc32/bits/long-double.h:
... here.
* sysdeps/unix/sysv/linux/sparc/sparc64/bits/long-double.h:

string/stratcliff.c: Replace int with size_t [BZ #21982]
Fix GCC 7 errors when string/stratcliff.c is compiled with -O3:
stratcliff.c: In function ‘do_test’:
cc1: error: assuming signed overflow does not occur when assuming that (X -
c) <= X is always true [-Werror=strict-overflow]
[BZ #21982]
* string/stratcliff.c (do_test): Declare size, nchars, inner,
middle and outer with size_t instead of int. Repleace %d and
%Zd with %zu in printf. Update "MAX (0, nchars - 128)" and
"MAX (outer, nchars - 64)" to support unsigned outer and
nchars.

string/stratcliff.c: Replace int with size_t [BZ #21982]
Fix GCC 7 errors when string/stratcliff.c is compiled with -O3:
stratcliff.c: In function ‘do_test’:
cc1: error: assuming signed overflow does not occur when assuming that (X -
c) <= X is always true [-Werror=strict-overflow]
[BZ #21982]
* string/stratcliff.c (do_test): Declare size, nchars, inner,
middle and outer with size_t instead of int. Repleace %d and
%Zd with %zu in printf. Update "MAX (0, nchars - 128)" and
"MAX (outer, nchars - 64)" to support unsigned outer and
nchars. Also exit loop when outer == 0.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77

Author: H.J. Lu <hjl.tools@gmail.com>

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Fix tgmath.h handling of complex integers (bug 21684).
The tgmath.h macros return a real type not a complex type when an
argument is of complex integer type (a GNU extension) and there are no
arguments of complex floating type. It seems clear that just as real
integers are mapped to double for tgmath.h, so complex integers should
be mapped to _Complex double.
This patch implements such a mapping. The main complication in fixing
this bug is that the tgmath.h macros expand their arguments a large
number of times, resulting in exponential blowup of the size of the
expansion when calls to tgmath.h macros are used in the arguments of
such macros; it would be unfortunate for fixing a bug with a fairly
obscure extension to make the macros expand their arguments even more
times. Thus, this patch optimizes the definitions of the relevant
macros. __tgmath_real_type previously expanded its argument 7 times
and now expands it 3 times. __tgmath_complex_type, used in place of
__tgmath_real_type only for functions that might return either real or
complex types, not for complex functions that always return real types
or always return complex types, expands its argument 5 times. So the
sizes of the macro expansions from nested macro calls are
correspondingly reduced (remembering that each tgmath.h macro expands
__tgmath_real_type, or sometimes now __tgmath_complex_type, several
times).
Sometimes the real return type resulted from calling a complex
function and converting the result to a real type; sometimes it
resulted from calling a real function, because the logic for
determining whether arguments were real or complex, based on sizeof,
was confused by integer promotions applying to e.g. short int but not
_Complex short int. The relevant tests are converted to use a new
macro __expr_is_real, which, by calling __builtin_classify_type rather
than comparing the results of two calls to sizeof, also reduces the
number of times macros expand their arguments.
Although there are reductions in the number of times macros expand
their arguments, I do not consider this to fix bug 21660, since a
proper fix means each macro expanding its arguments only once (via
using new compiler features designed for that purpose).
Tested for x86_64.

--- Comment #5 from Andy Lutomirski <luto at kernel dot org> ---
FWIW, I just tripped over this same bug again: Xen is a bit inconsistent as to
which SS value guest user code runs with, which means that guest user code can
sometimes inadvertently run with an SS value that Linux considers unusual,
which can trigger the legacy stack switching and cause random crashes due to
this glibc bug.

x86: Support IBT and SHSTK in Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a CET-enabled compiler, CET is enabled by
default, unless --disable-cet is used to configure glibc. When CET is
enabled, both compiler and assembler must support CET. Otherwise, it
is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property.

Bug ID: 21993
Summary: data type causing overflow in fwrite
Product: glibc
Version: 2.24
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: maninder1.s at samsung dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
We met with a situation where we are suspecting unsigned data type when
assigned a negative value
can cause overflow in glibc.
#1 __GI___mempcpy (dest=<optimized out>, src=src@entry=0x97fffcdc,
len=len@entry=4096) ---> crash
#2 __GI__IO_default_xsputn (f=f@entry=0xb24b7918, data=data@entry=0x97fffcdc,
n=n@entry=12396)
#3 _IO_new_file_xsputn (f=0xb24b7918, data=<optimized out>, n=16455)
#4 __GI__IO_fwrite (buf=0x97ffbd00, size=1, count=16455, fp=0xb24b7918)
So from application a valid address and valid size is passed to glibc fwrite
function.
but if we cehck frame 2 base address is increased by (0x97fffcdc - 0x97ffbd00)
= 16348 bytes and still n left is 12396
which leads to overflow and crash afterwards.
if we check code snippet:-
if (do_write)
{
count = new_do_write (f, s, do_write);
to_do -= count;
if (count < do_write)
return n - to_do;
}
In this code when we call new_do_write which calls _IO_SYSWRITE and which can
return -1 in failure case.
So comparison of unsigned data type(having -1) is not correct.
as count is IO_size_t , which is unsigned , so it should be IO_ssize_t as
_IO_SYSWRITE return _IO_ssize_t type.
We checked with small testcase:-
#include<stdio.h>
size_t test() {
return -1;
}
void main() {
size_t data = 13989;
size_t data1 = 27827;
size_t count;
count = test();
data -= count;
if(count < data1) {
printf("PASS %d\n", count);
return;
}
printf("FAIL %d \n", data);
}
output
# ./a.out
FAIL 13990
So can you please check whether it is correct or we are in wrong direction.

string/stratcliff.c: Replace int with size_t [BZ #21982]
Fix GCC 7 errors when string/stratcliff.c is compiled with -O3:
stratcliff.c: In function ‘do_test’:
cc1: error: assuming signed overflow does not occur when assuming that (X -
c) <= X is always true [-Werror=strict-overflow]
[BZ #21982]
* string/stratcliff.c (do_test): Declare size, nchars, inner,
middle and outer with size_t instead of int. Repleace %d and
%Zd with %zu in printf. Update "MAX (0, nchars - 128)" and
"MAX (outer, nchars - 64)" to support unsigned outer and
nchars. Also exit loop when outer == 0.

I don't think _IO_SYSWRITE will return zero in the failure case. Instead, it
will set the _IO_ERR_SEEN flag.

--- Comment #1 from Jason Holland <jester13rok at yahoo dot com> ---
I can confirm it is a bug, I'm specifically creating tm struct and noticed that
the December 31 1904 converts to 364 and December 31 1905 converts to 365. For
the person implementing the fix please be aware certain centuries are not a
leap year,
from wikipedia:
In the Gregorian calendar every year that is divisible by 400 is due to be an
end-of-century leap year (often called a century leap year), with the
intercalation of February 29 yielding 366 days instead of 365. End-of-century
years that are not divisible by 400 are common years (with 365 days) and not
leap years

My changes make code more readable I believe in case of comma-separated coding
mistake is possible (same happened with me also in past)

I found only two files where comma-separated is used.
also in glibc most of the places almost all dashed range is used
Example
sysdeps/arm/dl-trampoline.S
sysdeps/unix/sysv/linux/arm/setcontext.S

I agree no change in size also I did
basic verification with fwrite function I believe this code with hit when we
do fwrite also code is bit more readable

(In reply to Florian Weimer from comment #1)
> I don't think _IO_SYSWRITE will return zero in the failure case. Instead,

But as per our checking it is returning -1.
1298 _IO_size_t
1299 _IO_new_file_xsputn (_IO_FILE *f, const void *data, _IO_size_t n)
1300 {
...
1344 s += count;
1345 to_do -= count;
1346 }
==> at this point to_do value was 12395.
and at below code position it was increased by 1:-
1371 if (to_do)
1372 to_do -= _IO_default_xsputn (f, s+do_write, to_do); // tod:-12396
1373 }
Which means it is increased by 1, which is possible if
1360 if (do_write)
1361 {
1362 count = new_do_write (f, s, do_write);
1363 to_do -= count;
new_do_write returns -ve value, which means IO_SYSWRTE returns -ve value.
we are not sure about IO_SYSWRTE return value, but man page of write system
call says it will return -1 on failure.

My search was:
grep '{.*,.*}' `find . -name '*.S'|grep arm|sort`
Lots of the examples are false positives (not ranges of consecutive
registers, or only two consecutive registers, or consecutive registers
include sp/lr/pc which it's clearer not to include in ranges), but there
are plenty more files with comma-separated lists that could equally be
ranges than you mention. Quite possibly more than there are dashed
ranges.
> I agree no change in size also I did
It's not just the size you should compare. The actual binaries (the
complete contents of the lib/ directory in the installation, with all the
main shared libraries) should be byte-identical before and after such a
patch.

--- Comment #13 from Gabriel F. T. Gomes <gftg at linux dot vnet.ibm.com> ---
I posted a patch [1] to libc-alpha that addesses the problem with iszero and
-fsignaling-nans (if I'm not mistaken, this is the only problem mentioned in
this bug report that has not yet being dealt with).

--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Sounds like a bug in gold to me if the matherr and _LIB_VERSION symbols
don't end up with properly versioned dynamic symbols linked to those in
libm (though the case is slightly different from tst-mallocstate, in that
here matherr is being provided by the program, rather than only
referencing symbols defined in the shared library).

You could also try linking those tests with -rdynamic, as used by
tst-mallocstate, and see if that helps.

In that case, please send the patch to libc-alpha (though I'd encourage
raising the issue with the gold maintainers as well to see if the
difference from ld.bfd is deliberate).

Not by default, but with a new ARCH bit.

x86: Add MathVec_Prefer_No_AVX512 to cpu-features [BZ #21967]
AVX512 functions in mathvec are used on machines with AVX512. An AVX2
wrapper is also provided and it can be used when the AVX512 version
isn't profitable. MathVec_Prefer_No_AVX512 is addded to cpu-features.
If glibc.tune.hwcaps=MathVec_Prefer_No_AVX512 is set in GLIBC_TUNABLES
environment variable, the AVX2 wrapper will be used.
[BZ #21967]
* sysdeps/x86/cpu-features.h (bit_arch_MathVec_Prefer_No_AVX512):
New.
(index_arch_MathVec_Prefer_No_AVX512): Likewise.
* sysdeps/x86/cpu-tunables.c (TUNABLE_CALLBACK (set_hwcaps)):
Handle MathVec_Prefer_No_AVX512.

I stated a strong position here:
https://sourceware.org/ml/libc-alpha/2017-03/msg00430.html
I'm closing this as RESOLVED / WONTFIX for now.
Further discussions can happen on list or we can reopen this if we think there
is a technical solution we can pursue.

Bug ID: 22016
Summary: glibc-2.26 (and master) crashes on powerph with
--enable-stack-protector=all
Product: glibc
Version: 2.27
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: slyfox at inbox dot ru
Target Milestone: ---
Reproducible with various compilers: gcc-6.4.0, hcc-7.2.0, gcc-master
How to reproduce:
- build glibc on powerpc-unknown-linux-gnu as:
../glibc/configure --prefix=/usr --enable-stack-protector=all
- run dynamic loader as:
$ gdb --quiet --args elf/ld.so --library-path . /bin/ls
Reading symbols from elf/ld.so...done.
(gdb) run
Starting program: /root/glibc-build/elf/ld.so --library-path . /bin/ls
Program received signal SIGSEGV, Segmentation fault.
0x0fed1df8 in __GI___libc_malloc (bytes=5) at malloc.c:3062
3062 return (*hook)(bytes, RETURN_ADDRESS (0));
(gdb) list
3057 void *victim;
3058
3059 void *(*hook) (size_t, const void *)
3060 = atomic_forced_read (__malloc_hook);
3061 if (__builtin_expect (hook != NULL, 0))
3062 return (*hook)(bytes, RETURN_ADDRESS (0));
3063 #if USE_TCACHE
3064 /* int_free also calls request2size, be careful to not pad twice. */
3065 size_t tbytes = request2size (bytes);
3066 size_t tc_idx = csize2tidx (tbytes);
It's caused by a gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81996
where -fstack-protector-all makes compiler to read return address from
invalid stack.
I've filed a glibc bug for two reasons:
1. Would be nice if glibc would have a workaround of not generating
broken glibc on powerpc. I suggest adding '#define RETURN_ADDRESS(x) NULL'
or reading 'lr' register directly.
2. Would be nice if glibc did not use __builtin_return_address at all.
https://gcc.gnu.org/onlinedocs/gcc/Return-Address.html suggests it's
a debugging mechanism: """
Calling this function with a nonzero argument can have unpredictable effects,
including crashing the calling program. As a result, calls that are considered
unsafe are diagnosed when the -Wframe-address option is in effect. Such calls
should only be made in debugging situations. """
Even though RETURN_ADDRESS(0) is supposed to work practice shows it does not.
glibc fails on RETURN_ADDRESS(0) by trying to fetch 'lr' from stack:
... <something in __libc_malloc>...
0x0fed1df4 <+580>: lwz r10,32(r1)
=> 0x0fed1df8 <+584>: lwz r4,4(r10)
Thank you!

add check to getusershell() normal file is been read
Function does not work if someone puts in place of /etc/shells a symlink to
/dev/urandom for example. Fix is easy, various none-regular files should be
ignored. See attached patch how that could be dene.

Bug ID: 22019
Summary: Wrong placement of monetery symbol in el_GR (negative
amounts)
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: tzotzioy+bzl at gmail dot com
CC: libc-locales at sourceware dot org
Target Milestone: ---
In el_GR.UTF-8 the field n_cs_precedes is set to 1 while p_cs_precedes is set
to 0; this leads to the following formatting of monetary amounts:
* 16,20€
* -€16,80
This goes against common public usage of monetary amounts, and n_cs_precedes
should be set to 0 just like p_cs_precedes.
I understand that I should provide a link to a proper standard (assumably from
http://www.elot.gr/default_en.aspx , the Greek Standards Organisation) but it's
difficult to provide one (web searches did not produce results, so I have
contacted them by email and am still in the
wait-for-a-reply-by-someone-in-the-know phase). I will try to update the issue
with any relevant information.
In the meantime, I will see the proper way to submit a patch as an attachment
here.
(Unless I happen to locate some pointer to a standard in the
glibc/localedata/locales/el_GR change log.)

--- Comment #12 from VladimÃr ÄŒunát <vcunat at gmail dot com> ---
Thanks for fixing this!
Slightly off-topic - I'm rather scared when I see such comments in released
glibc versions:
/* FIXME This violates the mutex destruction requirements. See
__pthread_mutex_unlock_full. */
I would really hate to have to debug a situation where memory gets reused and
kernel writes into it at some point later. (I understand the triggering
situation might be considered unlikely, but still...)

mutex: Fix robust mutex lock acquire (Bug 21778)
65810f0ef05e8c9e333f17a44e77808b163ca298 fixed a robust mutex bug but
introduced BZ 21778: if the CAS used to try to acquire a lock fails, the
expected value is not updated, which breaks other cases in the loce
acquisition loop. The fix is to simply update the expected value with
the value returned by the CAS, which ensures that behavior is as if the
first case with the CAS never happened (if the CAS fails).
This is a regression introduced in the last release.
Tested on x86_64, i686, ppc64, ppc64le, s390x, aarch64, armv7hl.

rwlock: Fix explicit hand-over (bug 21298)
Without this fix, the rwlock can fail to execute the explicit hand-over
in certain cases (e.g., empty critical sections that switch quickly between
read and write phases). This can then lead to errors in how
__wrphase_futex
is accessed, which in turn can lead to deadlocks.

rwlock: Fix explicit hand-over (bug 21298)
Without this fix, the rwlock can fail to execute the explicit hand-over
in certain cases (e.g., empty critical sections that switch quickly between
read and write phases). This can then lead to errors in how
__wrphase_futex
is accessed, which in turn can lead to deadlocks.

The performance discrepancy does not show on master:
$ ./testcase-glibc-master
Run on (8 X 4400 MHz CPU s)
2017-08-28 12:49:33
***WARNING*** CPU scaling is enabled, the benchmark real time measurements may
be noisy and will incur extra overhead.
---------------------------------------------------------
Benchmark Time CPU Iterations
---------------------------------------------------------
BM_snprintf/10 43 ns 43 ns 16208239
BM_snprintf/100 44 ns 44 ns 15657047
BM_snprintf/1000 61 ns 61 ns 10386363
BM_snprintf/10000 244 ns 244 ns 3079929
I also does not show neither on 2.26 or 2.24, I only saw on 2.24. I can't
really pinpoint the exact commits that actually change this behavior, but I
take it fixed upstream.
As a side note, for future performance regression or enhancement please verify
against *master* branch, not on older releases (GLIBC 2.17 is five years old
and its branch is closed for backports [1]). Also, avoid running such benchmark
tests again distro releases since they usually incorporate backports and non
upstream patches.

commit 42496114ec0eb7d6d039d05d4262e109951c600c
Author: Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>

Provide a C++ version of iszero that does not use __MATH_TG (bug 21930)
When signaling nans are enabled (with -fsignaling-nans), the C++ version
of iszero uses the fpclassify macro, which is defined with __MATH_TG.
However, when support for float128 is available, __MATH_TG uses the
builtin __builtin_types_compatible_p, which is only available in C mode.
This patch refactors the C++ version of iszero so that it uses function
overloading to select between the floating-point types, instead of
relying on fpclassify and __MATH_TG.
Tested for powerpc64le, s390x, x86_64, and with build-many-glibcs.py.
[BZ #21930]
* math/math.h [defined __cplusplus && defined __SUPPORT_SNAN__]
(iszero): New C++ implementation that does not use
fpclassify/__MATH_TG/__builtin_types_compatible_p, when
signaling nans are enabled, since __builtin_types_compatible_p
is a C-only feature.
* math/test-math-iszero.cc: When __HAVE_DISTINCT_FLOAT128 is
defined, include ieee754_float128.h for access to the union and
member ieee854_float128.ieee.
[__HAVE_DISTINCT_FLOAT128] (do_test): Call check_float128.
[__HAVE_DISTINCT_FLOAT128] (check_float128): New function.
* sysdeps/powerpc/powerpc64le/Makefile [subdir == math]
(CXXFLAGS-test-math-iszero.cc): Add -mfloat128 to the build
options of test-math-zero on powerpc64le.

Bug ID: 22020
Summary: _SC_ATEXIT_MAX defined incorrectly, sysconf
(_SC_ATEXIT_MAX) is wrong
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Flags: security-
glibc defines _SC_ATEXIT_MAX, but this is incorrect according to POSIX. If the
limit is dependent on an unspecified quantity such as available system memory,
POSIX says that the constant shall not be defined.
In any case, the return value INT_MAX of sysconf (_SC_ATEXIT_MAX) is bogus.

--- Comment #1 from Carlos O'Donell <carlos at redhat dot com> ---
It's not entirely clear to me what should be returned or what should be
defined.
Are you suggesting we remove _SC_ATEXIT_MAX from limits.h, as the standard
suggests, for indeterminate limits?
If that is your suggestion, then we would need some way to verify that we
always have 32 atexit slots, since the limit removal is conditional on always
meeting the minimum.

We were often hitting this issue with some multithreaded binaries with many
shared libs. These patches referenced here, address the issue. Specifically:
https://patches.linaro.org/patch/85007/
https://patches.linaro.org/patch/85008/
These have been _extensively_ tested here with glibc-2.23 with many binaries

Even after this change, replacing /etc/shells with incorrect content can still
result in an unusable system, so I don't think this change is necessary.

I'm not sure how we could write a good configure test for this. Stack
protector is still not enabled by default.
There is no way to read lr directly because it may have already been clobbered
at the point the inline assembly runs.

Bug ID: 22025
Summary: iconv: Inconsistency between pointer mangling and NULL
checks
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: locale
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
We have an old downstream patch which addresses inconsistencies between pointer
mangling and NULL checks in the gconv/iconv code. The problem is caused by
checks like this:
/* Call the init function. */
if (result->__init_fct != NULL)
{
__gconv_init_fct init_fct = result->__init_fct;
#ifdef PTR_DEMANGLE
PTR_DEMANGLE (init_fct);
#endif
If the pointer guard happens to have the same bit pattern as init_fct, the NULL
check will incorrectly succeed.

--- Comment #4 from Mike FABIAN <maiku.fabian at gmail dot com> ---
FIXED (changing mon_decimal_point to "," for both ru_RU and os_RU,
I did not do any change to the currency symbol because neither
Wikipedia nor CLDR seem to have the “.†following the currency
symbol.)

Flags: security-
gen_steps decrements step_cnt twice on an error path.
if (__builtin_expect (status, __GCONV_OK) != __GCONV_OK)
{
failed = 1;
/* Make sure we unload this modules. */
--step_cnt;
result[step_cnt].__end_fct = NULL;
break;
}
As a result, the update of __end_fct is out of bounds:

I don't we ship any gconv modules where gconv_init can actually fail (on a
correctly configured system), so I'm flagging this as security-.

__end_fct must also be properly mangled on the error handling path.

Without a gconv function, we execute an error handling path which is not
prepared to deal with the inconsistency:

Error handling code:
found->fct = __libc_dlsym (found->handle, "gconv");
if (found->fct == NULL)
{
/* Argh, no conversion function. There is something
wrong here. */
__gconv_release_shlib (found);
found = NULL;
}
We probably need to set found->counter to 1 before calling
__gconv_release_shlib, or deallocate the half-initialized object in a different
manner.

Bug ID: 22028
Summary: bits/math-finite.h _MSUF_ expansion namespace
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
Target Milestone: ---
The current bits/math-finite.h approach to defining functions for different
types, involving math.h defining _MSUF_ and _MSUFTO_ for the function suffixes
involved, is not namespace-clean if one of those suffixes (f, l, f128) is
defined as a macro by the user before math.h is included; too many levels of
macro expansion occur. Instead, those suffixes should appear directly in the
expansion of the macro using ## so they don't get expanded even if defined as
macros by the user (that is, math.h should be defining __REDIRFROM_X and
__REDIRTO_X directly to use those suffixes rather than suffixes being passed as
an argument by macro callers).
Testing a patch.

gconv: Consistently mangle NULL function pointers [BZ #22025]
Not mangling NULL pointers is not safe because with very low
probability, a non-NULL function pointer can turn into a NULL pointer
after mangling.

Does that look correct to you?
It is the same as “India†written in the Bengali language:

commit 7daada0319613fec8c2a10b28eed911f4d359a6a
Author: Joseph Myers <joseph@codesourcery.com>

Fix bits/math-finite.h _MSUF_ expansion namespace (bug 22028).
The current bits/math-finite.h approach to defining functions for
different types, involving math.h defining _MSUF_ and _MSUFTO_ for the
function suffixes involved, is not namespace-clean if one of those
suffixes (f, l, f128) is defined as a macro by the user before math.h
is included; too many levels of macro expansion occur. Instead, those
suffixes should appear directly in the expansion of the macro using ##
so they don't get expanded even if defined as macros by the user (that
is, math.h should be defining __REDIRFROM_X and __REDIRTO_X directly
to use those suffixes rather than suffixes being passed as an argument
by macro callers). This patch makes that change.
Tested for x86_64.
[BZ #22028]
* math/math.h [__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0]
(_MSUF_): Remove macro.
[__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0] (_MSUFTO_):
Likewise.
[__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0]
(__REDIRFROM_X): New macro.
[__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0] (__REDIRTO_X):
Likewise.
* math/bits/math-finite.h (__REDIRFROM_X): Remove macro.
(__REDIRTO_X): Likewise.
(__MATH_REDIRCALL): Do not pass _MSUF_ or _MSUFTO_ macro
arguments.
(__MATH_REDIRCALL_2): Likewise.
(__MATH_REDIRCALL_INTERNAL): Likewise.
(__REDIRFROM (lgamma, , _MSUF_)): Likewise.
(__REDIRFROM (gamma, , _MSUF_)): Likweise.
(__REDIRFROM (__gamma, _r_finite, _MSUF_)): Likewise.
(__REDIRFROM (tgamma, , _MSUF_)): Likewise.
* math/test-finite-macros.c: New file.
* math/Makefile (tests): Add test-finite-macros.
(CFLAGS-test-finite-macros.c): New variable.

Bug ID: 22029
Summary: iconv: gconv callback function mangling easily
defeated
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: locale
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
Code like this (from wcsmbs/mbrtoc16.c:mbrtoc16) is problematic:
__gconv_fct fct = fcts->towc->__fct;
#ifdef PTR_DEMANGLE
if (fcts->towc->__shlib_handle != NULL)
PTR_DEMANGLE (fct);
#endif
status = DL_CALL_FCT (fct, (fcts->towc, &data, &inbuf, endbuf,
NULL, &dummy, 0, 1));
An attacker might just set __shlib_handle to NULL to avoid the need for
mangling the function pointer.
(Flagging as security- because this is merely hardening.)

--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
Just dropping the condition __shlib_handle != NULL does not work because
wcsmbs/wcmbsload.c supplies its own struct __gconv_step objects, via the failed
branch in __wcsmbs_load_conv.
We probably need to check for those two objects explicitly because
__wcsmbs_load_conv cannot allocate on the failure path, and we do not want to
move these objects into the .data segment.

Bug ID: 22030
Summary: openpty, forkpty interface is prone to buffer
overflows
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
The manual says this about openpty:
“
-- Function: int openpty (int *AMASTER, int *ASLAVE, char *NAME, const
struct termios *TERMP, const struct winsize *WINP)
[…]
If the argument NAME is not a null pointer, the file name of the slave
pseudo-terminal device is stored in ‘*name’.
â€
The caller does not supply any information about the size of the buffer at
NAME, so it is conceivable that it ends up being too small.
forkpty has the same issue.
See bug 13385 for another issue with this interface.

--- Comment #3 from Zsban Ambrus <ambrus at math dot bme.hu> ---
The texinfo maintainers have informed me that they have now fixed this bug in
version 6.4 of texinfo. Please install that version (or a later version) and
regenerate the online HTML-formatted version of the documentation at
"https://www.gnu.org/software/libc/manual/html_node/Copying.html".

ia64: Fix thread stack allocation permission set (BZ #21672)
This patch fixes ia64 failures on thread exit by madvise the required
area taking in consideration its disjoing stacks
(NEED_SEPARATE_REGISTER_STACK). Also the snippet that setup the
madvise call to advertise kernel the area won't be used anymore in
near future is reallocated in allocatestack.c (for consistency to
put all stack management function in one place).
Checked on x86_64-linux-gnu and i686-linux-gnu for sanity (since
it is not expected code changes for architecture that do not
define NEED_SEPARATE_REGISTER_STACK) and also got a report that
it fixes ia64-linux-gnu failures from Sergei Trofimovich
<slyfox@gentoo.org>.
[BZ #21672]
* nptl/allocatestack.c [_STACK_GROWS_DOWN] (setup_stack_prot):
Set to use !NEED_SEPARATE_REGISTER_STACK as well.
(advise_stack_range): New function.
* nptl/pthread_create.c (START_THREAD_DEFN): Move logic to mark
stack non required to advise_stack_range at allocatestack.c

when a 5-, 6- or 7-argument syscall wrapper is placed in a loop.
The cause of the problem is the use of `alloca' in regular MIPS/Linux
wrappers to force the use of the frame pointer register in any function
using one or more of these wrappers. Using the frame pointer register
is required so as not to break frame unwinding as the the stack pointer
is lowered within the inline asm used by these wrappers to make room for
the stack arguments, which 5-, 6- and 7-argument syscalls use with the
o32 ABI.
The regular MIPS/Linux wrappers are macros however, expanded inline, and
stack allocations made with `alloca' are not discarded until the return
of the function they are made in. Consequently if called in a loop,
then virtual memory is wasted, and if the loop goes through enough
iterations, then ultimately available memory can get exhausted causing
the program to crash.
Address the issue by replacing the inline code with standalone assembly
functions, which rely on the compiler arranging syscall arguments
according to the o32 function calling convention, which MIPS/Linux
syscalls also use, except for the syscall number passed and the error
flag returned. This way there is no need to fiddle with the stack
pointer anymore and all that has to be handled in the new standalone
functions is the special handling of the syscall number and the error
flag.
Redirect 5-, 6- or 7-argument MIPS16/Linux syscall wrappers to these new
functions as well, so as to avoid an unnecessary double call the
existing wrappers would cause with the new arrangement.

Bug ID: 22034
Summary: dlopen and cancellation
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: carlos at redhat dot com
Target Milestone: ---
Similar to bug 15686, a constructor (foreign function call) might call
functions which are cancellation points and under deferred cancellation the
thread will be cancelled leaving the dynamic loader internal locks held.
Subsequent dlopen's from another thread will deadlock. In this case we could
fix this by installing a cancel handler when dlopen starts running.
A perfect solution would be to avoid running the constructors with locks held
at all, but we need to advance the state of the dynamic loader internals
further to the point where we can snapshot link_map state and allow concurrent
dlopens.

Summary: [m68k] bits/math-inline.h macro namespace
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org

Target Milestone: ---
Host: m68k*-*-*
As shown by build bot failures
https://sourceware.org/ml/libc-testresults/2017-q3/msg00349.html
the m68k bits/mathinline.h is not namespace-clean: it fails to compile if the
user has defined macros f or l before it is included, because of expansions of
those arguments to __inline_functions.

commit 2f1aef195924fe33cd9d3f8772b2688ced7244ee
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Aug 29 21:07:51 2017 +0000
Fix m68k bits/math-inline.h macro namespace (bug 22035).
As shown by build bot failures
<https://sourceware.org/ml/libc-testresults/2017-q3/msg00349.html> the
m68k bits/mathinline.h is not namespace-clean: it fails to compile if
the user has defined macros f or l before it is included, because of
expansions of those arguments to __inline_functions. This patch
changes the __inline_functions definitions to take not the suffix but
a macro that concatenates it with the function name, to avoid the
spurious macro expansions.
Tested for m68k with build-many-glibcs.py.
[BZ #22035]
* sysdeps/m68k/m680x0/fpu/bits/mathinline.h (__inline_functions):
Define to take a second argument that is a macro that
concatentates a suffix, not the suffix itself.
(__CONCAT_d): New macro.
(__CONCAT_f): Likewise.
(__CONCAT_l): Likewise.

Joseph, I also think this shouldn't be tracked by a bugzilla but rather
discussed on maillist (as you already put [1]). Akhilesh, if you with to
continue in engage in this change please follow up on maillist instead. I will
close this bug by the end of the week.

Bug ID: 22040
Summary: dlopen: Provide more information on the root cause of
a failure
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
If dlopen fails, this can be due to a potentially transient issue (like lack of
file descriptors or memory), a fatal file system problem (media read error), a
file system contents issue (missing file, lack of access privileges), data
format issues (corrupted ELF data) or actual linking problems.
Internal use of dlopen within glibc needs to tell these errors apart. We have
several caches which should not treat a failed dlopen due to a transient
condition like a missing DSO. For example, the NSS service module cache should
not mark nss_dns as non-existent just because the system temporarily ran out of
file descriptors.
Parsing the output of dlerror is not a solution because it is too fragile.

Summary: libio: gconv initialization failure silently results

Product: glibc
Version: 2.26
Status: NEW

fwide-gconv-failure.c
If gconv initialization fails during a write operation, libio silently switches
to ASCII output instead, corrupting the data written data.
Expected output from the test is:
orientation (before write): no orientation yet
orientation (after write): wide-character oriented
data written: a6 ad 0a
Or a write failure. Current output is:
orientation (before write): no orientation yet
orientation (after write): wide-character oriented
data written: 3f 0a
(3f is ?, used here as a replacement character.)
I expect that a similar bug occurs during reading.

Bug ID: 22041
Summary: NSS persistently caches transient dlopen errors
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: nss
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Depends on: 22040
Target Milestone: ---
Flags: security-
This can lead to permanent loss of NSS functionality in a process:
https://sourceware.org/ml/libc-alpha/2017-08/msg00206.html
This is another potential root cause for the failure reported in bug 20532.
Dealing with dlopen failures requires proper failure detection and a new
(internal) interface; see bug 22040.

Alternatively, if we fix __wcsmbs_load_conv failure handling (bug 22039), we

--- Comment #2 from Florian Weimer <fweimer at redhat dot com> ---
__wcsmbs_load_conv needs to be fixed to return an error state, and _IO_fwide
and its callers need to handle the error.
The C standard seems to allow a failing fwide call (zero return value for a
non-zero mode argument).

malloc: Remove check_action variable [BZ #21754]
Clean up calls to malloc_printerr and trim its argument list.
This also removes a few bits of work done before calling
malloc_printerr (such as unlocking operations).
The tunable/environment variable still enables the lightweight
additional malloc checking, but mallopt (M_CHECK_ACTION)
no longer has any effect.

commit 4fa9b3bfe6759c82beb4b043a54a3598ca467289
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Aug 30 22:02:04 2017 +0000
Fix mcontext_t sigcontext namespace (bug 21457).
This patch completes the ucontext.h namespace fixes by fixing issues
related to the use of struct sigcontext as mcontext_t, and inclusion
of <bits/sigcontext.h> even when struct sigcontext is not so used.
Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the
way to get the sigcontext structure is by including <signal.h> (in a
context where __USE_MISC is defined); the sysdeps/generic version of
sys/ucontext.h keeps the inclusion by necessity, with a comment about
how this is not namespace-clean, but the only configuration that used
it, MicroBlaze, gets its own version of the header in this patch.
Where mcontext_t was typedefed to struct sigcontext, the contents of
struct sigcontext are inserted (with appropriate namespace handling to
prefix fields with __ when __USE_MISC is not defined); review should
check that this has been done correctly in each case, whether the
definition of struct sigcontext comes from glibc headers or from the
Linux kernel. This changes C++ name mangling on affected
architectures (which do not include x86_64/x86).
Tested for x86_64, and with build-many-glibcs.py.

Bug ID: 22050
Summary: Linking with -lmcheck does not hook
__malloc_initialize_hook correctly
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: mo at mightym0 dot de
Target Milestone: ---
Created attachment 10378
--> https://sourceware.org/bugzilla/attachment.cgi?id=10378&action=edit
Example code
I tested this with the 2.26 release as well as the latest HEAD of master
8325b477b1
GCC: gcc version 7.1.1 20170630 (GCC)
When linking with -lmcheck, the mcheck initialization should be triggered by
storing the address of turn_on_mcheck into the symbol __malloc_initialize_hook.
This symbol is checked by ptmalloc_init and called if present. However,
what happens when I try to link with -lmcheck, is a symbol is placed into the
binary's data section called "__malloc_initialize_hook". This symbol contains
the address of turn_on_mcheck. But when ptmalloc_init checks for the
__malloc_initialize_hook, it checks the actual symbol in the libc not in the
binary, so essentially the symbol exists twice and mcheck is never initialized.
At this point I'm pretty confused why this happens. The
__malloc_initialize_hook is defined in malloc-hooks.h and should be exported,
so I don't see why the duplicate symbol in the binary even exists.
It's very likely that I'm wrong and did some fundamental mistake,
but at this point I can't figure out what's wrong and hope that somebody either
spots a bug or my mistake.
Thank you
Moritz

* elf/sofini.c [HAVE_DWARF2_UNWIND_INFO]: Supply termination for
the frame unwind info section.
added
/* Terminate the frame unwind info section with a 4byte 0 as a sentinel;
this would be the 'length' field in a real FDE. */
typedef unsigned int ui32 __attribute__ ((mode (SI)));
static const ui32 __FRAME_END__[1]
__attribute__ ((used, section (".eh_frame")))
= { 0 };
to elf/sofini.c. Since libc.so is created with
# gcc -shared -static-libgcc ... elf/sofini.os .. -lgcc
The zero terminator is placed in the middle of glibc's .eh_frame due to object
files included from libgcc.a. Do we still need it today?

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Bug ID: 22053
Summary: Remove zero terminator for .eh_frame section in
elf/sofini.c
Product: glibc
Version: 2.27
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
elf/sofini.c has
/* Terminate the frame unwind info section with a 4byte 0 as a sentinel;
this would be the 'length' field in a real FDE. */
typedef unsigned int ui32 __attribute__ ((mode (SI)));
static const ui32 __FRAME_END__[1]
__attribute__ ((used, section (".eh_frame")))
= { 0 };
It was added before -eh-frame-hdr is added to ld. Since -eh-frame-hdr is
always used to build libc.so, zero terminator in elf/sofini.c can be
removed.

Not necessary because 24 hour time is used.

These seem to be correct already:
int_curr_symbol "DOP "
currency_symbol "RD$"
> - Fixed the "FIXME"
There is no “FIXME†anymore.
So I am not sure whether anything still needs to be done.
And there was no reply for a long time, so I close this as INVALID.
If you think that there is still a problem, you can reopen this
and provide a patch against current git.

Bug ID: 22057
Summary: mcheck does not set the using_malloc_checking flag, so
malloc_usable_size returns an invalid size
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: mo at mightym0 dot de
Target Milestone: ---
The using_malloc_checking flag is only set in the __malloc_check_init function,
which is called when enabling the additional security check via the environment
variable MALLOC_CHECK_.
This happens in the ptmalloc_init function, in case check_action was set.
However, if you enable the additional checks by either linking with -lmcheck or
calling mcheck yourself, __malloc_check_init is never called, so
using_malloc_checking is never set.
When someone calls malloc_usable_size now, ultimately musable will check if
using_malloc_checking is set and call the special malloc_check_get_size
function.
Because the bit isn't set malloc_usable_size will return the value at the
normal size location which is the hdr->magic2 field now, which is set to this:
hdr->magic2 = (uintptr_t) hdr ^ MAGICWORD;
While this will be rarely used apart from debugging, this could still have some
security implications as the value is most likely bigger than the actual size
and
if used for some bounds checking could lead to an overflow.

getaddrinfo: Fix error handling in gethosts [BZ #21915] [BZ #21922]
The old code uses errno as the primary indicator for success or
failure. This is wrong because errno is only set for specific
combinations of the status return value and the h_errno variable.

I recently removed all these “% Charset: ...†comments from the locale

commit 39b20aae21e4635296f4ebc4d80f4eb6c1cb4cbe
Author: Mike FABIAN <mfabian@redhat.com>
Date: Mon Aug 7 17:19:07 2017 +0200
Remove “% Charset: ...†comments from locale sources
These comments are useless and only confusing. The encodings used to
create binary locales from source locales are listed in the
localedata/SUPPORTED file. The source files itself are ASCII or UTF-8
encoded where non-ASCII UTF-8 is currently only used in comments. If
all locale source files are UTF-8 anyway, there is no need to specify
that in a special comment.
So I think we don’t need this “% Charset: ...†comment anymore.
[...]
+LC_IDENTIFICATION
+title "MÃskitu (agr) language locale for Nicaragua"
^^^ typo, should be miq I think.
+language "MÃskitu"
Should probably be “Miskitoâ€, https://en.wikipedia.org/wiki/Miskito_language
says:
“Miskito (MÃskitu in the Miskito language)â€
so “Miskito†seems to be the English name of this language and
the “language†tag in LC_IDENTIFICATION should contain the English name.
[...]
+LC_ADDRESS
+copy "es_NI"
+END LC_ADDRESS
It does not seem correct to copy this from "es_NI" because that would give us:
LC_ADDRESS
postal_fmt "%f%N%a%N/
%d%N%b%N%s/
%h %e %r%/
N%z %T%/
N%c%N"
country_name "Nicaragua"
country_ab2 "NI"
country_ab3 "NIC"
country_num 558
% NIC
country_car "NIC"
% Español
lang_name "español"
% es
lang_ab "es"
% spa
lang_term "spa"
% spa
lang_lib "spa"
END LC_ADDRESS
Which would make lang_name, lang_ab, lang_term, and lang_lib wrong.
Probably it should be:
LC_ADDRESS
postal_fmt "%f%N%a%N%d%N%b%N%s %h %e %r%N%z %T%N%c%N"
country_name "Nicaragua"
country_ab2 "NI"
country_ab3 "NIC"
country_num 558
country_car "NIC"
lang_name "M<U00ED>skitu"
lang_term "miq"
lang_lib "miq"
END LC_ADDRESS

Bug ID: 22062
Summary: Data race when reading configuration in
iconv/gconv_conf.c
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: locale
Assignee: unassigned at sourceware dot org
Reporter: arjun.is at lostca dot se
Target Milestone: ---
In iconv/gconv_conf.c:
__gconv_read_conf() does a lockless read on __gconv_path_elem (which can
potentially be written by another thread under a lock) to check if it is
already set or still NULL; if it is NULL, it calls __gconv_get_path() to set
it.
The code in __gconv_get_path() appears to (under a lock) first populate the
structure(s) pointed to by __gconv_path_elem and *then* set the pointer
variable itself.
This makes it appear that if thread 1 is executing __gconv_read_path() and does
the NULL test, and thread 2 is executing __gconv_get_path(), it would never
happen that the pointer is non-NULL while the block it points to is not
initialized. But potentially the processor can reorder the stores in thread 2
in a way that the pointer variable is set before the structure it points to is
filled out. This can lead to thread 1 operating on an uninitialized or
partially initialized structure array.

commit e0d2eb5a798613f9c24ad0056da86c8cfd19043d
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Mon Jun 26 11:52:14 2017 -0300
linux: Implement tmpfile with O_TMPFILE (BZ#21530)
This patch adds O_TMPFILE support to tmpfile on Linux. This is
similar to the previous suggestion by Andreas Schwab [1] with the
difference the file descriptor creation is parameterized to
compartmentalize Linux only open flags (O_TMPFILE) on sysdeps.
Checked on x86_64-linux-gnu.
Adhemerval Zanella <adhemerval.zanella@linaro.org>
Andreas Schwab <schwab@suse.de>
[BZ #21530]
* include/stdio.h (__gen_tempfd): New function.
* stdio-common/Makefile (routines): Add gentempfd.
* stdio-common/gentempfd.c: New file.
* sysdeps/unix/sysv/linux/gentempfd.c: Likewise.
* stdio-common/tmpfile.c (tmpfile): First try to use a system specific
unnamed file first.

Two more data points: This also causes trouble for the Ruby runtime when
configured to link against jemalloc. The full details are in
https://github.com/jemalloc/jemalloc/issues/1006 . We've also hit this in some
vendor-supplied code at Facebook.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

--- Comment #6 from Florian Weimer <fweimer at redhat dot com> ---
The posted patch does not work because it eliminates only one source of line
skipping (insufficient read buffer size). We still skip a line if it turns out
we cannot enlarge the pointer array during line parsing (or any other reason
why parsing might need more data from the buffer).
Back to the drawing board. I think we either have to use getline (which
requires additional copying) and preserve the line buffer across getent_r
invocations, or optimize ftello so that we can use it.

I'll mail a patch to delete the _SC_ATEXIT_MAX define.
> what should be returned
quoting http://pubs.opengroup.org/onlinepubs/009695399/functions/sysconf.html:
If the variable corresponding to name has no limit, sysconf() shall return -1
without changing the value of errno.
I'll send a patch.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

--- Comment #3 from Paul Pluzhnikov <ppluzhnikov at google dot com> ---
This seems to be much bigger problem than just _SC_ATEXIT_MAX:
1. we #define all kinds of other limits: _SC_ARG_MAX, _SC_THREADS, etc.
2. for all of them, we return -1 from getconf (good) while setting errno to
ENOSYS (bad).
2. we have no tests for any of this.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

--- Comment #14 from Mike Frysinger <vapier at gentoo dot org> ---
this bug report has a lot of things in it. i think each request in the
original post should be split out into sep reports. other than overall
discussion about keeping things in sync, it's impossible to follow discussion
about specific codepoints.

Bug ID: 22070
Summary: charmaps/UTF-8: wcwidth for
Prepended_Concatenation_Mark codepoints set to 0
(should be 1)
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: vapier at gentoo dot org
CC: libc-locales at sourceware dot org
Target Milestone: ---
we currently mark all Cf (Format Character) as width 0, but this ignores
Prepended_Concatenation_Mark codepoints. specifically these should all have a
wcwidth of 1:
0600..0605 ; Prepended_Concatenation_Mark # Cf ARABIC NUMBER SIGN..ARABIC
NUMBER MARK ABOVE
06DD ; Prepended_Concatenation_Mark # Cf ARABIC END OF AYAH
070F ; Prepended_Concatenation_Mark # Cf SYRIAC ABBREVIATION MARK
08E2 ; Prepended_Concatenation_Mark # Cf ARABIC DISPUTED END OF AYAH
110BD ; Prepended_Concatenation_Mark # Cf KAITHI NUMBER SIGN
Unicode 10.0.0 chapter 9 section 2 page 377-378 [1] states:
Signs Spanning Numbers. Several other special signs are written in association
with numbers in the Arabic script. All of these signs can span multiple-digit
numbers, rather than just a single digit. They are not formally considered
combining marks in the sense used by the Unicode Standard, although they
clearly interact graphically with their associated sequence of digits. In the
text representation they precede the sequence of digits that they span, rather
than follow a base character, as would be the case for a combining mark. Their
General_Category value is Cf (format character). Unlike most other format
characters, however, they should be rendered with a visible glyph, even in
circumstances where no suitable digit or sequence of digits follows them in
logical order. The characters have the Bidi_Class value of Arabic_Number to
make them appear in the same run as the numbers following them.
A few similar signs spanning numbers or letters are associated with scripts
other than Arabic. See the discussion of U+070F syriac abbreviation mark in
Section 9.3, Syriac, and the discussion of U+110BD kaithi number sign in
Section 15.2, Kaithi. All of these prefixed format controls, including the
non-Arabic ones, are given the property value
Prepended_Concatenation_Mark=True, to identify them as a class. They also have
special behavior in text segmentation. (See Unicode Standard Annex #29,
“Unicode Text Segmentation.â€)

Bug ID: 22073
Summary: charmaps/UTF-8: wcwidth of U+00AD: 0 or 1 ?
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: vapier at gentoo dot org
CC: egmont at gmail dot com, libc-locales at sourceware dot org,
maiku.fabian at gmail dot com, tg at mirbsd dot de
Depends on: 21750
Target Milestone: ---
+++ This bug was initially created as a clone of Bug #21750 +++
I’ve compared the new autogenerated column width from
localedata/unicode-gen/utf8_gen.py with the results of the classical wcwidth()
implementation from xterm (adjusted to Unicode 10.0.0) and found a few
divergences (and bugs on my (MirBSD, which uses something based on xterm’s data
system-wide) side, which I fixed).
U+00AD is forced to width 1 in xterm, autodetected as combining in glibc
Rationale for forcing it to 1 is likely that U+0000‥U+00FF are latin1, which,
when displayed as 8bit on terminals, had no combining characters at all.
Change Request to glibc: force U+00AD to width 1.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Summary: charmaps/UTF-8: wcwidth for U+1160-U+11FF (Hangul
Jungseong and Jongseong) should be 0
Product: glibc
Version: 2.26
Status: NEW
Severity: normal

Depends on: 21750
Target Milestone: ---
+++ This bug was initially created as a clone of Bug #21750 +++
I’ve compared the new autogenerated column width from
localedata/unicode-gen/utf8_gen.py with the results of the classical wcwidth()
implementation from xterm (adjusted to Unicode 10.0.0) and found a few
divergences (and bugs on my (MirBSD, which uses something based on xterm’s data
system-wide) side, which I fixed).
Hangul Jamo medial vowels and final consonants are set to 0 by xterm so they
combine on top of the preceding initial ones: U+1160‥U+11FF
Change Request to glibc: force U+1160‥U+11FF to width 0.
Markus Kuhn's implementation of wcwidth does this explicitly:
https://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
/* generated by "uniset +cat=Me +cat=Mn +cat=Cf -00AD +1160-11FF +200B c" */
Unicode 10.0.0 chapter 18 section 6 page 713 [1] states:
The Hangul Jamo block contains the most frequently used conjoining jamo. These
include all of the jamo used in modern Hangul syllable blocks, as well as many
of the jamo for Old Korean. The Hangul jamo are divided into three classes:
choseong (leading consonants, or syllable-initial characters), jungseong
(vowels, or syllable-peak characters), and jongseong (trailing consonants, or
syllable-final characters). Each class may, in turn, consist of one to three
subunits. For example, a choseong syllable-initial character may either
represent a single consonant sound, or a consonant cluster consisting of two or
three consonant sounds. Likewise, a jungseong syllable-peak character may
represent a simple vowel sound, or a complex diphthong or triphthong with
onglide or offglide sounds. Each of these complex sequences of two or three
sounds is encoded as a single conjoining jamo character. Therefore, a complete
Hangul syllable can always be conceived of as a single choseong followed by a
single jungseong and (optionally) a single jongseong. This block also contains
two invisible filler characters which act as placeholders for a missing
choseong or jungseong in an incomplete syllable. These filler characters are
U+115F hangul choseong filler and U+1160 hangul jungseong filler.
[1] http://www.unicode.org/versions/Unicode10.0.0/ch18.pdf
a concrete example, these three codepoints (one from each class):
á…” U+1154 Hangul Choseong Chitueumchieuch
á…¦ U+1166 Hangul Jungseong E
ᇯ U+11ef Hangul Jongseong Ieung-Khieukh
will form a single grapheme that should be wcwidth of 1:
ᅔᅦᇯ
the tricky part is that Jungseong & Jongseong conjoin only when they follow a
Choseong. so if you had a space U+0020 between each of those codepoints, you'd
end up with wcwidth of 5.

--- Comment #15 from Mike Frysinger <vapier at gentoo dot org> ---
i've forked soft hyphen (U+00AD) into bug 22073 and Hangul Jamo into bug 22074.
feel free to take follow ups for those topics to those respective bugs so the
discussion can stay focused and not get cluttered up.
i haven't looked into the other codepoints raised in the original comment, so
if they aren't resolved, feel free to fork them out too.

Aren't Korean chars usually full width? I.e. wcwidth 2.

But we cannot really do anything about the context, so we have to decide
for one width to use.

--- Comment #2 from Troy Korjuslommi <tjk at tksoft dot com> ---
I reached a totally different conclusion from reading those links and
thinking of the wcwidth(SHY) situation for wcwidth().
When writing a curses/terminfo (terminal) application, one goes through
input and determines the width of text by iterating through the input
characters. If a word contains multiple U+00AD characters, at the end of
the line or not, the total width of the word ends up wrong if wcwidth is
set to 1. Therefore wcwidth(U+00AD) should return 0.
Also, using a SHY (U+00AD) character as a rendering hint seems to make
sense, since if a word is broken up with SHY characters, then a SHY
aware application can determine where to break the word, adding a
visible hyphen only at that position. A SHY non-aware application can
just ignore the SHY.
The Korpela article shed light on the confusion standard writers have
had with the issue. It seems clear to me that their intention has been
to add a character which can be used as a hint for breaking words
according to hyphenation rules. The imprecise wording used for
describing the solution has led to the current confusion. We should get
past the semantics of the standards' phrases and focus on the intent,
which is to allow authors to add hyphenation hints to text.

Yes, but the characters we are discussing here are *parts*
of Korean characters, not *whole* Korean characters.
See Mike Frysinger’s example in comment#0.

commit 947e2e0a9410c18eb44144456c7fe8e7c0e2a999
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Aug 22 00:30:51 2017 +0000
Fix position of tests-unsupported definition in assert/Makefile.
tests-unsupported has to be defined before the inclusion of Rules in a
subdirectory Makefile; otherwise it is ineffective. This patch fixes
the ordering in assert/Makefile, where a recent test addition put
tests-unsupported too late (resulting in build failures when the C++
compiler was missing or broken, and thereby showing up the unrelated
bug 21987).
Incidentally, I don't see why these tests depend on
$(have-cxx-thread_local) rather than just a working C++ compiler.
Tested in such a configuration (broken compiler/libstdc++) with
build-many-glibcs.py.
* assert/Makefile [$(have-cxx-thread_local)]: Move conditional
variable definitions above inclusion of ../Rules.
(cherry picked from commit 75dfe623df945db7dd3c12a206d743c45c16b5ed)

For the code points
3248..324F;A # No [8] CIRCLED NUMBER TEN ON BLACK SQUARE..CIRCLED NUMBER EIGHTY
ON BLACK SQUARE
I asked on the unicode mailing list:
http://www.unicode.org/mail-arch/unicode-ml/y2017-m08/0007.html
And the response makes me think that we are free to use wcwidth 2 for
these in glibc if that fits our “context†best:

Bug ID: 22078
Summary: nss_files performance issue in multi mode
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: nss
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
nss_files, when finding additional addresses in multi mode for gethostbyname,
processes these addresses very inefficiently and needs a huge buffer as a
result.
For example, 64K addresses need a buffer size of more than 16 GiB (in fact, my
test allocates 32 GiB of memory).
This happens because for each new address, the entire array of the addresses
seen so far is copied into a fresh, enlarged array allocated from the buffer.
Overall buffer usage is thus super-linear.
The processing of aliases appears to be affected in a similar way.

This list is from
ftp://ftp.unicode.org/Public/10.0.0/ucd/PropList.txt
So maybe I should add that file as well to glibc/localedata/unicode-gen/
and parse it in glibc/localedata/unicode-gen/utf8_gen.py ?
(If this list never changes I could also hardcode it in utf8_gen.py).

--- Comment #4 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
As far as I can tell, the names such as _SC_ATEXIT_MAX *should* be defined
unconditionally; it's names such as ATEXIT_MAX that are omitted when the
limits are variable. What's the basis for saying _SC_ATEXIT_MAX should be
omitted?

Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Sep 4 16:27:16 2017 +0000
Fix bits/math-finite.h exp10 condition (bug 22082).
bits/math-finite.h handles exp10 if __USE_GNU. It should use the
condition __GLIBC_USE (IEC_60559_FUNCS_EXT), as in bits/mathcalls.h.
This patch fixes the condition.
Tested for x86_64.
[BZ #22082]
* math/bits/math-finite.h (exp10): Redirect if [__GLIBC_USE
(IEC_60559_FUNCS_EXT)], not [__USE_GNU].

--- Comment #4 from Thorsten Glaser <tg at mirbsd dot de> ---
> When writing a curses/terminfo (terminal) application, one goes through
> input and determines the width of text by iterating through the input
> characters. If a word contains multiple U+00AD characters, at the end of
> the line or not, the total width of the word ends up wrong if wcwidth is

In your reading, everything but the conclusion is* correct.
*) if the application uses the soft hyphen char as soft hyphen
Basically, if the application decides U+00AD is expanded into a hyphen,
it must send a hyphen, NOT U+00AD, to the terminal, and if not, it must
sende no character to the terminal.
The reason here is that wcwidth() is the _width of the character ON THE
TERMINAL_ and not for use within the application. No terminal will break
on the soft hyphen, they’ll all break only at the last column in the
line; therefore, wcwidth of U+00AD *must* be 1.
Further reasons: compatibility with previous wcwidth implementations,
and that the first 256 chars are supposed to be latin1 which had a
wcwidth of 1 for all non-control characters (20‥7E, A0‥FF).

getaddrinfo: Fix error handling in gethosts [BZ #21915] [BZ #21922]
The old code uses errno as the primary indicator for success or
failure. This is wrong because errno is only set for specific
combinations of the status return value and the h_errno variable.

commit 701f7873da013fb19d9120317322cd78333e63c2
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Sep 1 08:57:07 2017 +0200
getaddrinfo: Use &h_errno has the h_errno pointer
This simplifies the code because it is not necessary to propagate the
temporary h_errno value to the thread-local variable. It also increases
compatibility with NSS modules which update only one of the two places.

getaddrinfo: Use &errno has the errno pointer
Similar code in nss/getXXbyYY_r.c is already using &errno as the
argument.

getaddrinfo: Fix error handling in gethosts [BZ #21915] [BZ #21922]
The old code uses errno as the primary indicator for success or
failure. This is wrong because errno is only set for specific
combinations of the status return value and the h_errno variable.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

Bug ID: 22086
Summary: pcprofiledump incorrect cross-endian condition
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
debug/pcprofiledump.c contains code that tries to handle other-endian data.
This uses a condition "(word & 0xfffffff0) == bswap_32 (0xdeb00000)". This
condition is always false (the LHS always has the low four bits zero, the RHS
doesn't); a correct comparison would use 0x0fffffff. This results in
-Werror=tautological-compare build failures with the tile version of
bits/byteswap.h and mainline GCC.
https://sourceware.org/ml/libc-testresults/2017-q3/msg00400.html
pcprofiledump.c: In function 'main':
pcprofiledump.c:118:39: error: bitwise comparison always evaluates to false
[-Werror=tautological-compare]
int must_swap = (word & 0xfffffff0) == bswap_32 (0xdeb00000);

--- Comment #4 from Mike Frysinger <vapier at gentoo dot org> ---
(In reply to Mike FABIAN from comment #1)
> But we cannot really do anything about the context, so we have to decide
> for one width to use.
today that is true. long term, i think we'll need to figure out something
better similar to UAX29. it wouldn't help with wcwidth, but it would for
wcswidth.
http://www.unicode.org/reports/tr29/
so i think for today, supporting the common case and not the degenerate/invalid
cases makes sense. which is to say, marking them as wcwidth of 0.
(In reply to Troy Korjuslommi from comment #2)
> Aren't Korean chars usually full width? I.e. wcwidth 2.
the precomposed hangul forms are wcwidth of 2:
https://en.wikipedia.org/wiki/Hangul_Syllables
so i guess not only would we want to change the two sets to 0, we'd want to
change the first set to 2. that way we'd line up with the precomposed forms
better.
i think that should get us closer, but it'd still be an approximation. maybe
we should just focus on wcswidth here ?

--- Comment #5 from Mike Frysinger <vapier at gentoo dot org> ---
i don't think we have a choice here. if the rest of the world is converging on
the unicode standard view of the world, and it says 0, then we should do that
as well. trying to "take a stand" here won't help as long as the unicode
consortium doesn't change, and i think they've settled the matter in their
eyes. if you want to deliberate the topic further, it'd probably be better
spent doing so on their lists.
the unicode FAQ includes this entry [1] (which the korpela page called out):
Q: Unicode now treats the SOFT HYPHEN as format control (Cf) character when
formerly it was a punctuation character (Pd). Doesn't this break ISO 8859-1
compatibility?
A: No. The ISO 8859-1 standard defines the SOFT HYPHEN as "[a] graphic
character that is imaged by a graphic symbol identical with, or similar to,
that representing hyphen" (section 6.3.3), but does not specify details of how
or when it is to be displayed, nor other details of its semantics. The soft
hyphen has had a long history of legacy implementation in two or more
incompatible ways.
Unicode clarifies the semantics of this character for Unicode implementations,
but this does not affect its usage in ISO 8859-1 implementations. Processes
that convert back and forth may need to pay attention to semantic differences
between the standards, just as for any other character.
In a terminal emulation environment, particularly in ISO-8859-1 contexts, one
could display the soft hyphen as a hyphen in all circumstances. The change in
semantics of the Unicode character does not require that implementations of
terminal emulators in other environments, such as ISO 8859-1, make any change
in their current behavior.
[1] http://www.unicode.org/faq/casemap_charprop.html#18
i think that answers the question here: in our UTF-8 charmaps, we should mark
U+00AD as 0, but in our ISO 8859-1 (and other applicable legacy) charmaps, we
should mark it as 1.

commit 99d6791899c43eb31b4d1896134501d814da7741
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Sep 5 15:14:09 2017 +0000
Fix pcprofiledump cross-endian condition (bug 22086).
debug/pcprofiledump.c contains code that tries to handle other-endian
data. This uses a condition "(word & 0xfffffff0) == bswap_32
(0xdeb00000)". This condition is always false (the LHS always has the
low four bits zero, the RHS doesn't); a correct comparison would use
0x0fffffff. This results in -Werror=tautological-compare build
failures with the tile version of bits/byteswap.h and mainline GCC.
https://sourceware.org/ml/libc-testresults/2017-q3/msg00400.html
pcprofiledump.c: In function 'main':
pcprofiledump.c:118:39: error: bitwise comparison always evaluates to false
[-Werror=tautological-compare]
int must_swap = (word & 0xfffffff0) == bswap_32 (0xdeb00000);
^~
This patch fixes the condition. Tested for x86_64, and with
build-many-glibcs.py that it fixes the build for tilegx-linux-gnu.
(Note that I have not tested the actual pcprofiledump functionality,
native or cross endian, which lacks any testsuite coverage.)
[BZ #22086]
* debug/pcprofiledump.c (main): Use byte-swapped mask when
comparing word with byte-swapped constant.

(In reply to Mike FABIAN from comment #1)
right, thought i had mentioned PropList.txt here, but guess not.
we should update the python code to parse that db directly instead of
hardcoding anything. the latest update was in Unicode 5.2 (110BD), but it's
trivial to parse, so might as well be future proof.

Bug ID: 22088
Summary: malloc_check_get_size is not taking care of the
special header and eventually segfaults
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: mo at mightym0 dot de
Target Milestone: ---
malloc_check_get_size is called when using_malloc_checking is enabled.
This means malloc is using a different header defined in mcheck.c, which is not
compatible with the standard header.
However, malloc_check_get_size does the following to retrieve a chunks size:
for (size = chunksize (p) - 1 + (chunk_is_mmapped (p) ? 0 : SIZE_SZ);
chunksize is defined as:
#define chunksize(p) (chunksize_nomask (p) & ~(SIZE_BITS))
#define chunksize_nomask(p) ((p)->mchunk_size)
This means it will use the value at the size location in the standard header,
which corresponds to the magic2 field in the new header. This value is an xor
with the MAGICWORD 0xfedabeeb, which causes a very likely segfault in the next
line:
(c = ((unsigned char *) p)[size]) != magic;
In fact, malloc_check_get_size totally dismisses the fact that there is a
different header in play. Even the pointer that it gets as an argument points
to the beginning of the standard header, which is right in the middle of the
new
header. Furthermore, all macro functions like chunk2mem, mem2chunk,
chunk_is_mmapped, only handle the standard header case and need to be replaced
or wrapped.
This bug is somehow related to

[PATCH] locale: Call fchmod() before calling link()
From d25853801c2a3cb8357b75b750af12bc6b43f75f Mon Sep 17 00:00:00 2001
From: Colin Walters <walters@verbum.org>
Date: Tue, 5 Sep 2017 16:55:34 -0400
Subject: [PATCH] locale: Call fchmod() before calling link()
The [rpm-ostree](https://github.com/projectatomic/rpm-ostree)
project implements atomic, online system upgrades using
[libostree](https://github.com/ostreedev/ostree/), which
contains a `rofiles-fuse` program:
https://github.com/ostreedev/ostree/blob/master/man/rofiles-fuse.xml
Currently rpm-ostree will run all scripts, such as glibc's
`build-locale-archive` with an rofiles-fuse mount active. This fails
because we call `fchmod()` *after* calling `link()`, and `rofiles-fuse`
rejects writes to files with multiple links.
There's no reason not to call `fchmod()` beforehand in all cases, so let's do
so
and fix the `rofiles-fuse` case.

I think we already set the precomposed hangul to width 2 because of this line
AC00..D7A3;W # Lo [11172] HANGUL SYLLABLE GA..HANGUL SYLLABLE HIH
in EastAsianWidth.txt
we have
<UAC00>...<UD7A3> 2
in charmaps/UTF-8 in the WIDTH section.

Write all ranges of neighbouring characters with the same width using the
range notation in charmaps/UTF-8
Writing ranges of neighbouring characters with the same with like this
<U000E0100>...<U000E01EF> 0
in charmaps/UTF-8 is more efficient than writing many single character
lines
like:
<U000E0100> 0
<U000E0101> 0
...
[BZ #21750]
* unicode-gen/utf8_gen.py: Write all ranges of neighbouring characters

Bug ID: 22096
Summary: __resolv_conf_attach can incorrectly free passed conf
object
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: fweimer at redhat dot com
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
If the global conf array object cannot be allocated, __resolv_conf_attach frees
the passed-in conf object:
bool
__resolv_conf_attach (struct __res_state *resp, struct resolv_conf *conf)
{
assert (conf->__refcount > 0);
struct resolv_conf_global *global_copy = get_locked_global ();
if (global_copy == NULL)
{
free (conf);
return false;
}
…
This is wrong, it should simply leave its refcount unchanged and bail out.
I'm flagging this as security- even though it results in a use-after-free in
__res_vinit because it is difficult to trigger OOM in the required place.

--- Comment #6 from Thorsten Glaser <tg at mirbsd dot de> ---
Unicode does NOT define the column width of a char in the terminal. This shows
in all those mailing list threads, in which they basically assume all fonts to
be proportional.
wcwidth() however basically *is* the column width of a char in the terminal in
a fixed-width cell layout.
The cÅnsÄ“nsus seems to be to ask _users_ avoid using U+00AD because of the two
different histories in interpretation, and use something else for the separate
purposes. That leaves us with needing a definition for this char *should* it
appear anywhere still.
I’m arguing for 1 because:
• 0 is for combining characters and NUL only
• the “possible soft hyphen†reading of U+00AD is not a combining character
• compatibility with previous/older/other wcwidth() implementations, most
importantly
The 0 fraction should not be at a loss here because:
• The char should be avoided already *anyway*
• Terminal emulators never implement wrapping at a “possible soft hyphenâ€, only
at the end of the line
• Unicode data is still available elsewhere, this bugreport is precisely about
wcwidth() which only “almost†aligns with the various Unicode datas (yes, I
know, wrong plural, but I can’t think of anything better to express what I
mean, right now)

That could get ugly, assume you have an application displaying latin1 data on a
UTF-8 terminal (GNU screen comes to mind, or luit from XFree86®). Those map
0xAD to U+00AD not U+002D…
Given that mfabian as localedata maintainer of sorts has already accepted the
change, does it really still be needed to be discussed? (The copyright form
arrived last night btw, I’m sending it back to the FSF ASAP.)

Bug ID: 22099
Summary: getconf help info
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jg at jguk dot org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
I noticed two different types of help output. Examples below. The later
seems a little hard to comprehend. Could they be unified?
$ getconf
Usage: getconf [-v specification] variable_name [pathname]
getconf -a [pathname]
$ getconf --help
Usage: getconf [-v SPEC] VAR
or: getconf [-v SPEC] PATH_VAR PATH
Get the configuration value for variable VAR, or for variable PATH_VAR
for path PATH. If SPEC is given, give values for compilation
environment SPEC.
$ getconf --version
getconf (Ubuntu GLIBC 2.23-0ubuntu9) 2.23
Expected:
Also the addition of
getconf --help Show this help
getconf --version Show version number

--- Comment #8 from Mike Frysinger <vapier at gentoo dot org> ---
(In reply to Thorsten Glaser from comment #6)
i'm aware wcwidth isn't explicitly defined by Unicode standards, but that
doesn't mean they completely ignore it. they discuss terminal emulators
multiple times (including the SHY FAQ), and it's why things like
EastAsianWidth.txt exist in the first place. it's also pretty clear what the
current Unicode standard is wrt their intentions to this codepoint.
> • 0 is for combining characters and NUL only
that is incorrect. you mishandle Prepended_Concatenation_Mark (see bug 22070),
and ignore Format Character (Cf) characters which are all 0 (or you're
incorrectly claiming that Cf's are not combining characters). and which U+00AD
is classified as.
> • the “possible soft hyphen†reading of U+00AD is not a combining character
except that it is. if Unicode wanted it to be an explicit hyphen, they would
have kept its class as Pd (punctuation character), not changed it to Cf (format
control). they also wouldn't have described it explicitly as:
Soft Hyphen. Despite its name, U+00AD soft hyphen is not a hyphen, but rather
an
invisible format character used to indicate optional intraword breaks.
> • compatibility with previous/older/other wcwidth() implementations, most
> importantly
appealing to historical wcwidth behavior isn't a great argument. ones written
to older Unicode standards are def wrong across many codepoints (emoji much?),
and as i already mentioned, implementations converge on the latest Unicode
releases. all of which say this should be 0.
> • The char should be avoided already *anyway*
> • Terminal emulators never implement wrapping at a “possible soft hyphenâ€,
> only at the end of the line
then by your own argument, having it follow the Unicode standard is a non-issue
(In reply to Thorsten Glaser from comment #7)
if your terminal and the target application disagree about encoding then you've
already lost. everything above 0x7F will be wrong (0x80 != U+0080 or 0xc2
0x80).

Bug ID: 22101
Summary: dlopen crash with SIGSEGV when opening debug SO
Product: glibc
Version: 2.27
Status: UNCONFIRMED
Severity: critical
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: jobol at nonadev dot net
Target Milestone: ---
Opening a "debug" shared object leads to crash.
If I split a shared object library using "objcopy --only-keep-debug", opening
the produced library with dlopen raise a SIGSEGV.
This happened with yocto/openembedded that separate debugging symbols and place
it in separate .debug directory. The issue came when scanning for shared
libraries recursively and opening found .so files (by example, yocto installs:
ROOT/x.so and ROOT/.debug/x.so) then opening the debug shared object was made.
Is there an easy way to know that a shared object is for debug symbols? I don't
found one except that ldconfig says "statically linked" (or something like
that, meaning that there is no dependency to any other library). But using
dlopen is the prefered way, dlopen that should fail in that case but not
SIGSEGV.

OK, sorry about that. But xterm handles even those as such, basically
it combines the glyph for it (could be blank or just the dotted square)
over the preceding character, as they have no meaning for a terminal.

But this is more important than you make it sound.

Sure, which is why I updated it to use the current Unicode data
as base, but there are a few cases which were specifically handled
explicitly different right from the start, and, with the changes
I described, mfabian’s code in glibc and mine in MirBSD come to
the same result modulo implementation differences.
(I also handle Prepended_Concatenation_Mark in MirBSD now in the
way you requested in bz#22070, so compatibility goes both ways.
My focus was on updating mgk25’s code in a compatible way, as to
not introduce any regressions; changes from later Unicode changes
are welcome, as are initial oversights such as this one (if it
existed back then), but as I said, U+00AD was special-handled
right from the beginning.)

There is no Unicode standard for wcwidth().

It’s not because with 0, applications displaying a simple charmap
for the first page (i.e. latin1) fail on X'AD'.

You did not understand what I wrote.
Tools like GNU screen and XFree86® luit can convert between the encodings,
so they’d convert an \xA0 from the program (meaning an 0x80 in latin1) to
a U+00A0 internally to a \xC2\xA0 in UTF-8 to the screen, and back.
The *definition* of these mappings maps 0xAD from latin1 to U+00AD, not to
U+002D. (Changing _this_ would also be unwise as there’d be no way to type
latin1 0xAD any more.)
Therefore, wcwidth(U+00AD) should stay at 1.
PS: Discussing this is really straining for me, and English is only my third
non-programming language, so please read anything weird as I mean it, not as I
formulated it.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

--- Comment #11 from Egmont Koblinger <egmont at gmail dot com> ---
To clarify my previous comment:
If compatibility is a concern then let's go with 1, I'm absolutely fine with
that.
If compatibility is not such of a concern, it feels to me that -1 is a more
reasonable choice than 0.
Basically, out of the three possibilities 0 is the one I find the least
reasonable. As for the other two, my guts feeling tell me to go with the
backwards compatible 1, however, you guys have way better arguments pro or con
than guts feeling so I cannot join that discussion.

--- Comment #12 from Egmont Koblinger <egmont at gmail dot com> ---
To further clarify:
By "compatibility" I meant compatibility with existing legacy apps.
Compatibility with (or let's rather say: proper implementation of) the recent
Unicode standard, if we're okay with dropping backwards compatibility, is where
I feel -1 might perhaps be the best choice.
Either-or, I can't really see 0 being justified.

From the man page of wcwidth:
The wcwidth() function returns the number of columns needed
to represent the wide character c. If c is a printable wide
character, the value is at least 0. If c is null wide
character (L'\0'), the value is 0. Otherwise, -1 is
returned.
The soft hyphen is printable (it is in the section “print†of LC_CTYPE
in localedata/locales/i18n), therefore the value returned by wcwidth()
is at least 0. So -1 is not possible for the soft hyphen.

--- Comment #14 from Egmont Koblinger <egmont at gmail dot com> ---
My recommendation to consider was to make wcwidth return -1 and, in the mean
time, mark it as non-printable. As far as I understand, properly written apps
should never print this character, right?

--- Comment #15 from Egmont Koblinger <egmont at gmail dot com> ---
Don't get me wrong... I'm not saying that this is the solution we should go
with. I'm not arguing that -1 is the best choice. I just wanted to make sure
that this possibility is also considered.
If the final decision is 1, I'm absolutely fine with that.
If the final decision is 0, I wouldn't be that happy because then I think -1 is
a better choice, however, I'd still accept that decision.
I justed wanted to give a heads up about a third possibility that probably
wouldn't have been considered otherwise. The rest is up to you guys. Thanks for
listening to me! :)

Bug ID: 22111
Summary: Maloc's new per thread cache is not returned when
thread exits
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: zegentzy at protonmail dot com
Target Milestone: ---
Created attachment 10403
--> https://sourceware.org/bugzilla/attachment.cgi?id=10403&action=edit
Makes 1000 batches of 10 threads then ends them. Then prints out memory
consumption before exiting.
Description:
glibc 2.26 now enables a per-thread cache to malloc by default. This cache
consumes around 1.23 kB of memory per thread created.
This cache however is not released when the thread exits. This cache can't be
detected with malloc_heap() causing many/most memory profiling tools (memcheck,
massif, heapcheck, etc) unable to either detect a) its existence or b) its
source.
For applications which create and remove lots of threads, this can quickly
consume gigabytes of memory, with the source of the consumption appearing to be
unknown.
This issue was originally reported in 2010 at
https://bugzilla.redhat.com/show_bug.cgi?id=640286 and
https://bugzilla.redhat.com/show_bug.cgi?id=598498
I rereported this issue 3 days ago here: https://bugs.archlinux.org/task/55532
Additional info:
Happens in: glibc 2.26-1 and glibc 2.26-2
Steps to reproduce:
1) Compile attached file.

https://www.cs.tut.fi/~jkorpela/shy.html quotes ISO 8859-1 standard as:

So according to this, it should be printable.

Bug ID: 22114
Summary: xdr_char() and xdr_u_char() functions crashes on
encoding of character lying in constant memory segment
Product: glibc
Version: 2.17
Status: UNCONFIRMED
Keywords: glibc_2.17
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: a.kampling at gmx dot de
Target Milestone: ---
The bug I report here was detected in the glibc 2.17 but can also be found in
the codebase of the current head in the git repository:
https://sourceware.org/git/?p=glibc.git;a=blob_plain;f=sunrpc/xdr.c;hb=HEAD.
The "xdr_xxx()" functions can be used to encode and decode data into an xdr
object.
The "bool_t xdr_char (XDR *xdrs, char *cp)" function will crash if the data
that is passed via "char *cp" is lying in a constant memory segment.
The other functions like "xdr_int()" checks wether to encode or decode and just
writes to the pointer target if decoding should take place.
So instead of crashing the function should just encode the data and not write
to where the pointer is pointing to.
I know that the argument is not: "const char *cp" but the other functions
behave differently in contrast to "xdr_char()".
Further the "xdr_u_char()" function is also affected of the same problem
--------------------------------------
Steps to reproduce (C program):
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <rpc/rpc.h>
int main()
{
static const char cchar = 'a';
static const int cint = 42;
char xdrbuffer[100];
XDR xdrs;
xdrmem_create(&xdrs, xdrbuffer, sizeof(xdrbuffer), XDR_ENCODE);
// works
printf("xdr_int: <%s>\n",
(xdr_int(&xdrs, &cint) == TRUE) ? "Success" : "Failure");
// fails --> segmentation fault!
printf("xdr_char: <%s>\n",
(xdr_char(&xdrs, &cchar) == TRUE) ? "Success" : "Failure");
return 0;
}
--------------------------------------
valgrind crash log:

==42507== For counts of detected and suppressed errors, rerun with: -v

Segmentation fault
Solution:
The bug is on this line in the xdr.c
https://sourceware.org/git/?p=glibc.git;a=blob;f=sunrpc/xdr.c;h=8b0b91995b79b859a8ff12d81f1720368b645b16;hb=HEAD#l414:
*cp = i;
This should just be done if
xdrs->x_op
is equal to
XDR_DECODE.
The other functions like "xdr_int()" are using a switch case for that.

posix: Use enum for __glob_pattern_type result
This patch replaces the internal integer constant from
__glob_pattern_type return with a proper enum.
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
* posix/glob_internal.h (glob_pattern_type_t): New enumeration.
(__glob_pattern_type): Use __glob_pat_types.
* posix/glob_pattern_p.c (__glob_pattern_p): Likewise.
* posix/glob.c (glob): Likewise.
(glob_in_dir): Likewise.

posix: Consolidate Linux glob implementation
This patch consolidates the glob implementation. The main changes are:
* On Linux all implementation now uses the default one at
sysdeps/unix/sysv/linux/glob{free}{64}.c with the exception
of alpha (which requires specific versioning) and s390-32 (which
different than other 32 bits ports it does not add a compat one
symbol for 2.1 version).
* The default implementation uses XSTAT_IS_XSTAT64 to define whether
both glob{free} and glob{free}64 should be different implementations.
For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias
to glob{free}64.
* Move i386 olddirent.h header to Linux default directory, since it is

posix: fix glob bugs with long login names
Current glob implementation allows unlimited user name for home
directory construction on GLOB_TILDE case. To accomplish it glob
either construct a name on stack if size are small enough (based
on current alloca_used) or in heap otherwise.
This patch simplifies storage allocation by using the same scratch
buffer for both get_rlogin_r and getpwnam_r.
This also syncs with gnulib commit 064df0b (glob: fix bugs with long
login names).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
* posix/glob.c (GET_LOGIN_NAME_MAX): Remove.
(glob): Use the same scratch buffer for both getlogin_r and
getpwnam_r. Don’t require preallocation of the login name. This
simplifies storage allocation, and corrects the handling of
long login names.

posix: Allow glob to match dangling symlinks [BZ #866]
This patch makes glob match dangling symlinks. Compared to other glob
implementation (*BSD, bash, musl, and other shells as well), GLIBC seems
the be the only one that does not match dangling symlinks. As for
comment #5 in BZ #866, POSIX does not have any strict specification for
dangling symlinks match and it is reasonable that trying to glob everything
in a path should return all types of files (such as for a 'rm *'). Also,
comment #7 shows even more example where GLIBC current behavior is
unexepected.
I avoided adding another GNU specific flag to set this behavior and
instead make it the default. Although this change the semanthic from
previous implementation, I think adding another compat symbol to be
really unecessary as from aforementioned reasons (current behavior not
defined in any standard, general idea of different implementation is
to list dangling symbols).
This also sync glob with gnulib commit fd1daf4 (glob: match dangling
symlinks).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

posix: accept inode 0 is a valid inode number (BZ #19971)
According to this kernel commit 2adc376c55194, d_ino 0 is a regular inode
number on Linux (which also matches POSIX, as it does not treat the value
as special). This patch makes glob accept is a valid inode number.

posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version
b5ec983 (glob: simplify symlink detection). The only difference
to gnulib code is
* DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there
were not already defined. Gnulib code which uses
HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because
GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead
the patch check for each definition instead.
Also, the patch requires additional globfree and globfree64 files
for compatibility version on some architectures. Also the code
simplification leads to not macro simplification (not need for
NO_GLOB_PATTERN_P anymore).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
[BZ #1062]
* posix/Makefile (routines): Add globfree, globfree64, and
glob_pattern_p.

[NDEBUG): Remove comments.
(GLOB_ONLY_P, _AMIGA, VMS): Remove define.
(dirent_type): New type. Use uint_fast8_t not
uint8_t, as C99 does not require uint8_t.
(DT_UNKNOWN, DT_DIR, DT_LNK): New macros.
(struct readdir_result): Use dirent_type. Do not define skip_entry
unless it is needed; this saves a byte on platforms lacking d_ino.
(readdir_result_type, readdir_result_skip_entry):
New functions, replacing ...
(readdir_result_might_be_symlink, readdir_result_might_be_dir):
these functions, which were removed. This makes the callers
easier to read. All callers changed.
(D_INO_TO_RESULT): Now empty if there is no d_ino.
(size_add_wrapv, glob_use_alloca): New static functions.
(glob, glob_in_dir): Check for size_t overflow in several places,
and fix some size_t checks that were not quite right.
Remove old code using SHELL since Bash no longer
uses this.
(glob, prefix_array): Separate MS code better.
(glob_in_dir): Remove old Amiga and VMS code.
(globfree, __glob_pattern_type, __glob_pattern_p): Move to
separate files.
(glob_in_dir): Do not rely on undefined behavior in accessing
struct members beyond their bounds. Use a flexible array member
instead
(link_stat): Rename from link_exists2_p and return -1/0 instead of
0/1. Caller changed.
(glob): Fix memory leaks.
* posix/glob64 (globfree64): Move to separate file.

posix: Consolidate Linux glob implementation
This patch consolidates the glob implementation. The main changes are:
* On Linux all implementation now uses the default one at
sysdeps/unix/sysv/linux/glob{free}{64}.c with the exception
of alpha (which requires specific versioning) and s390-32 (which
different than other 32 bits ports it does not add a compat one
symbol for 2.1 version).
* The default implementation uses XSTAT_IS_XSTAT64 to define whether
both glob{free} and glob{free}64 should be different implementations.
For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias
to glob{free}64.
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different
architectures (and used on compat glob symbol as well).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
* sysdeps/unix/sysv/linux/arm/glob64.c: Remove file.
* sysdeps/unix/sysv/linux/i386/glob64.c: Likewise.
* sysdeps/unix/sysv/linux/m68k/glob64.c: Likewise.

posix: fix glob bugs with long login names
Current glob implementation allows unlimited user name for home
directory construction on GLOB_TILDE case. To accomplish it glob
either construct a name on stack if size are small enough (based
on current alloca_used) or in heap otherwise.
This patch simplifies storage allocation by using the same scratch
buffer for both get_rlogin_r and getpwnam_r.
This also syncs with gnulib commit 064df0b (glob: fix bugs with long
login names).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
* posix/glob.c (GET_LOGIN_NAME_MAX): Remove.
(glob): Use the same scratch buffer for both getlogin_r and
getpwnam_r. Don’t require preallocation of the login name. This
simplifies storage allocation, and corrects the handling of
long login names.

posix: Allow glob to match dangling symlinks [BZ #866]
This patch makes glob match dangling symlinks. Compared to other glob
implementation (*BSD, bash, musl, and other shells as well), GLIBC seems
the be the only one that does not match dangling symlinks. As for
comment #5 in BZ #866, POSIX does not have any strict specification for
dangling symlinks match and it is reasonable that trying to glob everything
in a path should return all types of files (such as for a 'rm *'). Also,
comment #7 shows even more example where GLIBC current behavior is
unexepected.
I avoided adding another GNU specific flag to set this behavior and
instead make it the default. Although this change the semanthic from
previous implementation, I think adding another compat symbol to be
really unecessary as from aforementioned reasons (current behavior not
defined in any standard, general idea of different implementation is
to list dangling symbols).
This also sync glob with gnulib commit fd1daf4 (glob: match dangling
symlinks).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

posix: accept inode 0 is a valid inode number (BZ #19971)
According to this kernel commit 2adc376c55194, d_ino 0 is a regular inode
number on Linux (which also matches POSIX, as it does not treat the value
as special). This patch makes glob accept is a valid inode number.
This is also a sync with gnulib commit c8e57c1.

posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version
b5ec983 (glob: simplify symlink detection). The only difference
to gnulib code is
* DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there
were not already defined. Gnulib code which uses
HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because
GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead
the patch check for each definition instead.
Also, the patch requires additional globfree and globfree64 files
for compatibility version on some architectures. Also the code
simplification leads to not macro simplification (not need for
NO_GLOB_PATTERN_P anymore).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
[BZ #1062]
* posix/Makefile (routines): Add globfree, globfree64, and
glob_pattern_p.

[NDEBUG): Remove comments.
(GLOB_ONLY_P, _AMIGA, VMS): Remove define.
(dirent_type): New type. Use uint_fast8_t not
uint8_t, as C99 does not require uint8_t.
(DT_UNKNOWN, DT_DIR, DT_LNK): New macros.
(struct readdir_result): Use dirent_type. Do not define skip_entry
unless it is needed; this saves a byte on platforms lacking d_ino.
(readdir_result_type, readdir_result_skip_entry):
New functions, replacing ...
(readdir_result_might_be_symlink, readdir_result_might_be_dir):
these functions, which were removed. This makes the callers
easier to read. All callers changed.
(D_INO_TO_RESULT): Now empty if there is no d_ino.
(size_add_wrapv, glob_use_alloca): New static functions.
(glob, glob_in_dir): Check for size_t overflow in several places,
and fix some size_t checks that were not quite right.
Remove old code using SHELL since Bash no longer
uses this.
(glob, prefix_array): Separate MS code better.
(glob_in_dir): Remove old Amiga and VMS code.
(globfree, __glob_pattern_type, __glob_pattern_p): Move to
separate files.
(glob_in_dir): Do not rely on undefined behavior in accessing
struct members beyond their bounds. Use a flexible array member
instead
(link_stat): Rename from link_exists2_p and return -1/0 instead of
0/1. Caller changed.
(glob): Fix memory leaks.
* posix/glob64 (globfree64): Move to separate file.

posix: Consolidate Linux glob implementation
This patch consolidates the glob implementation. The main changes are:
* On Linux all implementation now uses the default one at
sysdeps/unix/sysv/linux/glob{free}{64}.c with the exception
of alpha (which requires specific versioning) and s390-32 (which
different than other 32 bits ports it does not add a compat one
symbol for 2.1 version).
* The default implementation uses XSTAT_IS_XSTAT64 to define whether
both glob{free} and glob{free}64 should be different implementations.
For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias
to glob{free}64.
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different
architectures (and used on compat glob symbol as well).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

posix: fix glob bugs with long login names
Current glob implementation allows unlimited user name for home
directory construction on GLOB_TILDE case. To accomplish it glob
either construct a name on stack if size are small enough (based
on current alloca_used) or in heap otherwise.
This patch simplifies storage allocation by using the same scratch
buffer for both get_rlogin_r and getpwnam_r.
This also syncs with gnulib commit 064df0b (glob: fix bugs with long
login names).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
* posix/glob.c (GET_LOGIN_NAME_MAX): Remove.
(glob): Use the same scratch buffer for both getlogin_r and
getpwnam_r. Don’t require preallocation of the login name. This
simplifies storage allocation, and corrects the handling of
long login names.

posix: Allow glob to match dangling symlinks [BZ #866]
This patch makes glob match dangling symlinks. Compared to other glob
implementation (*BSD, bash, musl, and other shells as well), GLIBC seems
the be the only one that does not match dangling symlinks. As for
comment #5 in BZ #866, POSIX does not have any strict specification for
dangling symlinks match and it is reasonable that trying to glob everything
in a path should return all types of files (such as for a 'rm *'). Also,
comment #7 shows even more example where GLIBC current behavior is
unexepected.
I avoided adding another GNU specific flag to set this behavior and
instead make it the default. Although this change the semanthic from
previous implementation, I think adding another compat symbol to be
really unecessary as from aforementioned reasons (current behavior not
defined in any standard, general idea of different implementation is
to list dangling symbols).
This also sync glob with gnulib commit fd1daf4 (glob: match dangling
symlinks).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

[BZ #1062]
* posix/Makefile (tests): Remove bug-glob1 and tst-glob_symlinks.
* posix/bug-glob1.c: Remove file.

(link_stat, link_exists_p): Remove. All uses removed.

posix: accept inode 0 is a valid inode number (BZ #19971)
According to this kernel commit 2adc376c55194, d_ino 0 is a regular inode
number on Linux (which also matches POSIX, as it does not treat the value
as special). This patch makes glob accept is a valid inode number.
This is also a sync with gnulib commit c8e57c1.
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version
b5ec983 (glob: simplify symlink detection). The only difference
to gnulib code is
* DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there
were not already defined. Gnulib code which uses
HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because
GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead
the patch check for each definition instead.
Also, the patch requires additional globfree and globfree64 files
for compatibility version on some architectures. Also the code
simplification leads to not macro simplification (not need for
NO_GLOB_PATTERN_P anymore).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
[BZ #1062]
* posix/Makefile (routines): Add globfree, globfree64, and
glob_pattern_p.
* posix/flexmember.h: New file.
* posix/glob_internal.h: Likewise.

* posix/glob.c (HAVE_CONFIG_H): Use !_LIBC instead.
[NDEBUG): Remove comments.
(GLOB_ONLY_P, _AMIGA, VMS): Remove define.
(dirent_type): New type. Use uint_fast8_t not
uint8_t, as C99 does not require uint8_t.
(DT_UNKNOWN, DT_DIR, DT_LNK): New macros.
(struct readdir_result): Use dirent_type. Do not define skip_entry
unless it is needed; this saves a byte on platforms lacking d_ino.
(readdir_result_type, readdir_result_skip_entry):
New functions, replacing ...
(readdir_result_might_be_symlink, readdir_result_might_be_dir):
these functions, which were removed. This makes the callers
easier to read. All callers changed.
(D_INO_TO_RESULT): Now empty if there is no d_ino.
(size_add_wrapv, glob_use_alloca): New static functions.
(glob, glob_in_dir): Check for size_t overflow in several places,
and fix some size_t checks that were not quite right.
Remove old code using SHELL since Bash no longer
uses this.
(glob, prefix_array): Separate MS code better.
(glob_in_dir): Remove old Amiga and VMS code.
(globfree, __glob_pattern_type, __glob_pattern_p): Move to
separate files.
(glob_in_dir): Do not rely on undefined behavior in accessing
struct members beyond their bounds. Use a flexible array member
instead
(link_stat): Rename from link_exists2_p and return -1/0 instead of
0/1. Caller changed.
(glob): Fix memory leaks.
* posix/glob64 (globfree64): Move to separate file.
* sysdeps/gnu/glob64.c (NO_GLOB_PATTERN_P): Remove define.
(globfree64): Remove hidden alias.
* sysdeps/unix/sysv/linux/Makefile (sysdeps_routines): Add
oldglob.
* sysdeps/unix/sysv/linux/alpha/glob.c (__new_globfree): Move to
separate file.
* sysdeps/unix/sysv/linux/i386/glob64.c (NO_GLOB_PATTERN_P): Remove
define.
Move compat code to separate file.
* sysdeps/wordsize-64/glob.c (globfree): Move definitions to
separate file.

This has been mostly fixed by this commit:
commit 54d68f5f61fc016b18101a822f9343a612ad1bc0
Author: Mike FABIAN <mfabian@redhat.com>
Date: Mon Aug 14 19:48:27 2017 +0200
Change language name in LC_IDENTIFICATION of bn_BD and bn_IN from “Bengaliâ€
to “Banglaâ€
[BZ #14925]
* locales/bn_BD (LC_IDENTIFICATION): Change language name in
“title†and “language†from Bengali to Bangla.
* locales/bn_IN (LC_IDENTIFICATION): Likewise.
But when checking again now, I found that “Bengali†was still there
in a few comments in bn_BD, in iso-639.def and in a test input file.
I am changing it there as well.

--- Comment #3 from Mike FABIAN <maiku.fabian at gmail dot com> ---
CLDR makes no difference for the weekday abbreviations in the
various German locales, they all share the same weekday
abbreviations.
http://www.unicode.org/repos/cldr/trunk/common/main/de.xml
has:
<days>
<dayContext type="format">
<dayWidth type="abbreviated">
<day type="sun">So.</day>
<day type="mon">Mo.</day>
<day type="tue">Di.</day>
<day type="wed">Mi.</day>
<day type="thu">Do.</day>
<day type="fri">Fr.</day>
<day type="sat">Sa.</day>
</dayWidth>
<dayWidth type="narrow">
<day type="sun">S</day>
<day type="mon">M</day>
<day type="tue">D</day>
<day type="wed">M</day>
<day type="thu">D</day>
<day type="fri">F</day>
<day type="sat">S</day>
</dayWidth>
<dayWidth type="short">
<day type="sun">So.</day>
<day type="mon">Mo.</day>
<day type="tue">Di.</day>
<day type="wed">Mi.</day>
<day type="thu">Do.</day>
<day type="fri">Fr.</day>
<day type="sat">Sa.</day>
</dayWidth>
<dayWidth type="wide">
<day type="sun">Sonntag</day>
<day type="mon">Montag</day>
<day type="tue">Dienstag</day>
<day type="wed">Mittwoch</day>
<day type="thu">Donnerstag</day>
<day type="fri">Freitag</day>
<day type="sat">Samstag</day>
</dayWidth>
</dayContext>
<dayContext type="stand-alone">
<dayWidth type="abbreviated">
<day type="sun">So</day>
<day type="mon">Mo</day>
<day type="tue">Di</day>
<day type="wed">Mi</day>
<day type="thu">Do</day>
<day type="fri">Fr</day>
<day type="sat">Sa</day>
</dayWidth>
<dayWidth type="narrow">
<day type="sun">S</day>
<day type="mon">M</day>
<day type="tue">D</day>
<day type="wed">M</day>
<day type="thu">D</day>
<day type="fri">F</day>
<day type="sat">S</day>
</dayWidth>
<dayWidth type="short">
<day type="sun">So.</day>
<day type="mon">Mo.</day>
<day type="tue">Di.</day>
<day type="wed">Mi.</day>
<day type="thu">Do.</day>
<day type="fri">Fr.</day>
<day type="sat">Sa.</day>
</dayWidth>
<dayWidth type="wide">
<day type="sun">Sonntag</day>
<day type="mon">Montag</day>
<day type="tue">Dienstag</day>
<day type="wed">Mittwoch</day>
<day type="thu">Donnerstag</day>
<day type="fri">Freitag</day>
<day type="sat">Samstag</day>
</dayWidth>
</dayContext>
</days>
I.e. the 2-letter abbreviations without dots are used for "stand-alone",
"abbreviated"
whereas the 2-letter abbreviations with dots are used for "stand-alone",
"short",
and for "format", "abbreviated" and for "format", "short".
And none of the de_*.xml files overrides this, so it is the same
for all German locales.
So it doesn’t look like there needs to be a difference between
Switzerland and Germany here according to CLDR.
If you really believe there should be a difference, can you please open
a bug with CLDR?

--- Comment #1 from Carlos O'Donell <carlos at redhat dot com> ---
I can confirm this issue exists. I believe I see the problem. We are leaking
the tcache structure on each thread exit. I'm testing a fix. Thanks for the
report.

--- Comment #2 from Carlos O'Donell <carlos at redhat dot com> ---
Note that this issue has nothing to do with the originally referenced issues in
comment #0. The issue here is that we don't set tcache_shutting_down early
enough, and therefore it causes a reinitialization of the tcache (to a new
tcache) and the about-to-be-freed old tcache structure chunk is placed back
into the new tcache.
After the fix:
[carlos@koi swbz22111]$ ./libc_leakNEW
/proc/self/status at exit
VmPeak: 883040 kB
VmSize: 694568 kB
VmLck: 0 kB

VmStk: 132 kB
VmExe: 4 kB
VmLib: 1944 kB
VmPTE: 96 kB
VmPMD: 16 kB
VmSwap: 0 kB
The VmRSS is now back down to 1.5MB which is expected.
The fix itself is relatively straight forward:

--- Comment #4 from keld at keldix dot com <keld at keldix dot com> ---
Hi
I think we should have an entry for POSIX-like day and month abbreviations,
that should be
3 letters wide.
I do not think we need to coordinate all our data with CLDR, I actually think
we have a
very active community that is capable of maintaining our inforation ourselves.
So no need to open bug requests with CLDR - but of cause we should try to align
with them, and they with us.
I believe there is a difference in month names between Germany and Austria.
Best regrds

Summary: tst-udp-error may fail if CLONE_NEWNET is not
available
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc

Target Milestone: ---
Hello,
I'm having issues with tst-udp-error when CLONE_NEWNET is not available,
because bad luck can make it that the client connection happens to get
the same port as the closed server, here is an example trace.
First tst-udp-error sets the server and closes it:
[pid 19899] socket(AF_INET, SOCK_DGRAM|SOCK_CLOEXEC, IPPROTO_IP) = 3
[pid 19899] bind(3, {sa_family=AF_INET, sin_port=htons(0),
sin_addr=inet_addr("127.0.0.1")}, 16) = 0
[pid 19899] getsockname(3, {sa_family=AF_INET, sin_port=htons(40000),
sin_addr=inet_addr("127.0.0.1")}, [16]) = 0
[pid 19899] close(3) = 0
Then clnt_call tries to bind to a privileged port, but can because we
don't have CLONE_NEWNET:
[pid 19899] socket(AF_INET, SOCK_DGRAM|SOCK_NONBLOCK, IPPROTO_UDP) = 3
[pid 19899] bind(3, {sa_family=AF_INET, sin_port=htons(996),
sin_addr=inet_addr("0.0.0.0")}, 16) = -1 EACCES (Permission denied)
[pid 19899] setsockopt(3, SOL_IP, IP_RECVERR, [1], 4) = 0
then it sends the request to the server
[pid 19899] sendto(3,
"\36\353\0330\0\0\0\0\0\0\0\2\0\0\0\1\0\0\0\2\0\0\0\3\0\0\0\0\0\0\0\0"..., 40,
0, {sa_family=AF_INET, sin_port=htons(40000), sin_addr=inet_addr("127.0.0.1")},
16) = 40
but actually receives it! (instead of getting an error for the send)
[pid 19899] poll([{fd=3, events=POLLIN}], 1, 1000) = 1 ([{fd=3,
revents=POLLIN}])
[pid 19899] recvfrom(3,
"\36\353\0330\0\0\0\0\0\0\0\2\0\0\0\1\0\0\0\2\0\0\0\3\0\0\0\0\0\0\0\0"...,
8800, MSG_DONTWAIT, {sa_family=AF_INET, sin_port=htons(40000),
sin_addr=inet_addr("127.0.0.1")}, [16]) = 40
[pid 19899] write(1, "error: tst-udp-error.c:56: not t"..., 158error:
tst-udp-error.c:56: not true: clnt_call (clnt, 3, (xdrproc_t) xdr_void, NULL,
(xdrproc_t) xdr_void, NULL, ((struct timeval) { 3, 0 })) == RPC_CANTRECV
That's because the system happened to bind the client socket to port
40000 too because of bad luck.

Yes, there is a difference in the month names. In de_AT and de_IT
the name for January is “Jännerâ€, in the other German locales it is
“Januarâ€.
But there is no difference in the weekday names among the German locales.
There maybe some difference in how to abbreviate the weekday names,
the reference given in
https://sourceware.org/bugzilla/show_bug.cgi?id=20482
says that weekdays in German speaking regions of Switzerland should
be abbreviated with two letters without a dot.
The reference gived to the Duden in comment#0 of this bug here
seems less convincing to me.
And CLDR does not make any difference in the weekday abbreviations
between any of the German locales.
CLDR has both the versions with and without the dots for different
types of abbreviations but no difference between the German locales.
I, personally, as German native speaker would tend to use the dots
if using the abbreviation in a full date like “So. 10. 09. 2017â€
but without the dots if labelling columns of a calendar like
September 2017
So Mo Di Mi Do Fr Sa
1 2
3 4 5 6 7 8 9
10 11 12 13 14 15 16
17 18 19 20 21 22 23
24 25 26 27 28 29 30
But that is only my personal opinion.
And I don’t find the reference given in comment#0 of this bug
particularly convincing, as it does not talk at all about
the context in which the abbreviation is used.
The reference given in
https://sourceware.org/bugzilla/show_bug.cgi?id=20482
does not talk about the context either, it unconditionally
says that no dots should be used.
Overall I think the two letter abbreviations without the dots
we have at the moment are reasonably good.
I would like to change this only if somebody comes up
with really better references why a change is needed.
Maybe discussing with CLDR upstream why they have the
current weekday abbreviations for German and why they
make no difference between the different German locales
helps to sort this out.

Sorry, the referenced issues gave exactly so I thought that was it.
Anyways, I've compiled glibc with those two lines changed and its fixed, YAY!
Should I mark this issue as resovled, or should I wait tell it gets merged or
something?

Thanks for testing. The patch will have to be posted to the mailing list,
committed, and then we can close the bug. Backporting to the 2.26 release
branch is also needed.

--- Comment #17 from Troy Korjuslommi <tjk at tksoft dot com> ---
I would like to point out that wcwidth of 1 for SHY would mean that
applications which haven't taken soft hyphens into consideration, as
they are rare in actual input, will display words with SHY in them very
awkwardly. Namely, as "the-os-o-phy" or "the os o phy." The actual
display will of course depend on the font in use. It can resemble a
hyphen or a space. Applications which are SHY aware, will of course
handle it separately, either breaking the word and adding a hyphen or
ignoring it.
I might add that I speculate that the reason SHY is so rarely used is
because of these kinds of disagreements over its display.
I don't see any disagreement over the intent of the SHY, so why not make
the lives of writers (who could then start including SHY in text) and
programmers (who would then find it worthwhile to write special handlers
for SHY).

--- Comment #7 from Troy Korjuslommi <tjk at tksoft dot com> ---
I was referring to the "should be wcwidth of 1" comment, which doesn't
seem to be correct. My point was that the wcwidth should be either 0 or
two.

x86: Add x86_64 to x86-64 HWCAP [BZ #22093]
Before glibc 2.26, ld.so set dl_platform to "x86_64" and searched the
"x86_64" subdirectory when loading a shared library. ld.so in glibc
2.26 was changed to set dl_platform to "haswell" or "xeon_phi", based
on supported ISAs. This led to shared library loading failure for
shared libraries placed under the "x86_64" subdirectory.
This patch adds "x86_64" to x86-64 dl_hwcap so that ld.so will always
search the "x86_64" subdirectory when loading a shared library.
NB: We can't set x86-64 dl_platform to "x86-64" since ld.so will skip
the "haswell" and "xeon_phi" subdirectories on "haswell" and "xeon_phi"
machines.
Tested on i686 and x86-64.
[BZ #22093]
* sysdeps/x86/cpu-features.c (init_cpu_features): Initialize
GLRO(dl_hwcap) to HWCAP_X86_64 for x86-64.
* sysdeps/x86/dl-hwcap.h (HWCAP_COUNT): Updated.
(HWCAP_IMPORTANT): Likewise.
(HWCAP_X86_64): New enum.
(HWCAP_X86_AVX512_1): Updated.
* sysdeps/x86/dl-procinfo.c (_dl_x86_hwcap_flags): Add "x86_64".
* sysdeps/x86_64/Makefile (tests): Add tst-x86_64-1.
(modules-names): Add x86_64/tst-x86_64mod-1.
(LDFLAGS-tst-x86_64mod-1.so): New.
($(objpfx)tst-x86_64-1): Likewise.
($(objpfx)x86_64/tst-x86_64mod-1.os): Likewise.
(tst-x86_64-1-clean): Likewise.
* sysdeps/x86_64/tst-x86_64-1.c: New file.
* sysdeps/x86_64/tst-x86_64mod-1.c: Likewise.

(In reply to Troy Korjuslommi from comment #17)

That is done even when wcwidth(U+00AD) == 1, because the application would
never send U+00AD to the tty but always either no character or one of the
other hyphen-ish codepoints.
In fact, if a font renders U+00AD different from U+002D, an SHY-aware
application might even PREFER it to have wcwidth 1 because then it COULD
send U+00AD to the tty *in the places where it expands to a hyphenation*
(and just omit it where not).
For GUI applications, wcwidth() is of no meaning anyway.
> awkwardly. Namely, as "the-os-o-phy" or "the os o phy." The actual
“the-os-o-phy†(“theo-sophy†is how I’d split it, though) is common for
the soft hyphenation point editing mode of word processors.

string/stratcliff.c: Replace int with size_t [BZ #21982]
Fix GCC 7 errors when string/stratcliff.c is compiled with -O3:
stratcliff.c: In function ‘do_test’:
cc1: error: assuming signed overflow does not occur when assuming that (X -
c) <= X is always true [-Werror=strict-overflow]
[BZ #21982]
* string/stratcliff.c (do_test): Declare size, nchars, inner,
middle and outer with size_t instead of int. Repleace %d and
%Zd with %zu in printf. Update "MAX (0, nchars - 128)" and
"MAX (outer, nchars - 64)" to support unsigned outer and
nchars. Also exit loop when outer == 0.
(cherry picked from commit 376b40a27a6783ea7f73ae577be320df66aeb36d)

commit 4e4cfd77617c190a7c8b3f83c41e1ad0771bd569
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Mon Sep 11 08:51:52 2017 -0700
string/stratcliff.c: Replace int with size_t [BZ #21982]
Fix GCC 7 errors when string/stratcliff.c is compiled with -O3:
stratcliff.c: In function ‘do_test’:
cc1: error: assuming signed overflow does not occur when assuming that (X -
c) <= X is always true [-Werror=strict-overflow]
[BZ #21982]
* string/stratcliff.c (do_test): Declare size, nchars, inner,
middle and outer with size_t instead of int. Repleace %d and
%Zd with %zu in printf. Update "MAX (0, nchars - 128)" and
"MAX (outer, nchars - 64)" to support unsigned outer and
nchars. Also exit loop when outer == 0.
(cherry picked from commit 376b40a27a6783ea7f73ae577be320df66aeb36d)

commit b64e0298661a084d8aab6756b08dbced515449d8
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Mon Sep 11 09:04:57 2017 -0700
Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from
"#include_next" (instead of stdlib/stdlib.h in the glibc source
directory), and this turns up as a make dependency. Also make a copy
of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h.
* configure.ac (find_cxx_header): Suppress compiler error message.
* configure: Regenerated.
[BZ #21573]
* Makerules [$(c++-bits-std_abs-h) != ""] (before-compile): Add
$(common-objpfx)bits/std_abs.h.
[$(c++-bits-std_abs-h) != ""] ($(common-objpfx)bits/std_abs.h):
New target.
* config.make.in (c++-bits-std_abs-h): New.
* configure.ac (find_cxx_header): Use "\,$1," with sed.
(CXX_BITS_STD_ABS_H): New.
(AC_SUBST(CXX_BITS_STD_ABS_H)): Likewise.
* configure: Regenerated.
(cherry picked from commit a65ea28d1833d3502c5070472e43bda04410e6b5 and
commit c2528fef3b05bcffb1ac27c6c09cc3ff24b7f03f)

Bug ID: 22125
Summary: Incorrect feature test macro markings for
pthread_mutexattr_setrobust() and
pthread_mutexattr_getrobust()
Product: glibc
Version: 2.27
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: mtk.manpages at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
The macro guarding pthread_mutexattr_setrobust() and
pthread_mutexattr_getrobust() in sysdeps/nptl/pthread.h is __USE_XOPEN2K.
However, these two APIs first appeared in POSIX.1-2008/SUSv4. Therefore, the
macro should be __USE_XOPEN2K8.
Note that the closely related pthread_mutex_consistent(), which also first
appeared in POSIX.1-2008/SUSv4, is correctly guarded with __USE_XOPEN2K8 in the
same header file.

x86: Add MathVec_Prefer_No_AVX512 to cpu-features [BZ #21967]
AVX512 functions in mathvec are used on machines with AVX512. An AVX2
wrapper is also provided and it can be used when the AVX512 version
isn't profitable. MathVec_Prefer_No_AVX512 is addded to cpu-features.
If glibc.tune.hwcaps=MathVec_Prefer_No_AVX512 is set in GLIBC_TUNABLES
environment variable, the AVX2 wrapper will be used.
Tested on x86-64 machines with and without AVX512. Also verified
glibc.tune.hwcaps=MathVec_Prefer_No_AVX512 on AVX512 machine.
[BZ #21967]
* sysdeps/x86/cpu-features.h (bit_arch_MathVec_Prefer_No_AVX512):
New.
(index_arch_MathVec_Prefer_No_AVX512): Likewise.
* sysdeps/x86/cpu-tunables.c (TUNABLE_CALLBACK (set_hwcaps)):
Handle MathVec_Prefer_No_AVX512.
* sysdeps/x86_64/fpu/multiarch/ifunc-mathvec-avx512.h
(IFUNC_SELECTOR): Return AVX2 version if MathVec_Prefer_No_AVX512
is set.

Does it means that dlopen is authorized to crash (SIGSEGV)?
I don't share your opinion.

--- Comment #19 from Troy Korjuslommi <tjk at tksoft dot com> ---
I was referring to non-SHY-aware apps. When iterating through input in
curses code, one needs wcwidth() for at least two reasons. One is to
calculate space needed to display a word, and the other is to determine
the position of the cursor (only applicable when input contains 2 column
wide characters). If SHY is wcwidth other than 0, the non-SHY-aware
applications will calculate the width incorrectly.
A non-SHY-aware application could easily add the U+00AD to the terminal,
and thus possibly cause cursor movement, and maybe even character
rendering, to occur.
An author who cares about grammar would actually hyphenate theosophy as
"the-o-so-phy." That was kind of my point, that words with more than two
syllables have two or more hyphens. And that hyphenation is a rule based
system, non-obvious and hard to guess, which is why SHY can be a useful
tool.

There's two sides to this story: apps and terminal emulators. You seem to care
about apps here, and forgot that altering wcwidth might have an effect on
terminal emulators' behavior as well.
If all parties respect wcwidth() then either 0 or 1 is okay. In case of 0 the
terminal emulator will not print anything nor advance the cursor, in accordance
with what the app expects. In case of 1 the outcome again will be correct.
The story is about to foresee the impacts of apps as well as terminal emulators
(and their combinations) that use hardcoded values rather than wcwidth. For
example, I don't know if xterm always uses its built-in table, or only in
certain cases; nor whether its author is open to adjust the table to follow
what gets decided in this bugreport. There's also vte's (gnome-terminal's)
issue of using glib's method instead, but I can most likely change that if
really needed.
(Plus, again, let's not forget about the case of ssh'ing between different
systems, potentially either one not even glibc-based.)

I think there is nothing more to do in this bug here,
therefore I close it as FIXED.

commit 799c8d6905433ad56f26ccab4855b36f1d1ddbfc
Author: Mike FABIAN <mfabian@redhat.com>
Date: Thu Sep 7 15:28:28 2017 +0200
Add new codepage charmaps/IBM858 [BZ #21084]
This code page is identical to code page 850 except that X'D5'
has been changed from LI61 (dotless i) to SC20 (euro symbol).
The code points from /x01 to /x1f in the /localedata/charmaps/IBM858
file have the same mapping as those in localedata/charmaps/ANSI_X3.4-1968.
That means they disagree with with
ftp://ftp.software.ibm.com/software/globalization/gcoc/attachments/CP00858.txt
in that range.
For example, localedata/charmaps/IBM858 and
localedata/charmaps/ANSI_X3.4-1968 have:
“<U0001> /x01 START OF HEADING (SOH)â€
whereas CP00858.txt has:
“01 SS000000 Smiling Faceâ€
That means that CP00858.txt is not really ASCII-compatible and to make
it ASCII-compatible we deviate fro CP00858.txt in the code points from /x01
to /x1f.
[BZ #21084]
* benchtests/strcoll-inputs/filelist#en_US.UTF-8: Add IBM858 and
ibm858.c.
* iconvdata/Makefile: Add IBM858.
* iconvdata/gconv-modules: Add IBM858.
* iconvdata/ibm858.c: New file.
* iconvdata/tst-tables.sh: Add IBM858
* localedata/charmaps/IBM858: New file.

Yes, that would be correct. The terminal is, in your terminology, *also*
a non-SHY-aware application.

No, actually, if wcwidth is anything other than *1* they will calculate
it incorrectly, because, to a terminal, the character will always have
a constant width. (If wcwidth were 0 and an SHY-aware application were
to send U+00AD to the terminal in the place where a break DOES occur,
the terminal could NOT emit a space-using glyph otherwise.)

Indeed, both use wcwith() and thus have to agree.

One more point in favour of letting it stay at 1 to stay compatible with
everyone else in the world including previous releases.

Either that, or add special handling of a couple of characters to vte…
it’ll likely handle stuff like direction changes or so already if it’s
not just a dumb terminal like xterm, so there’s bound to be a correct
place for it.

This is not an invalid bug, but a failure of the GNU toolchain to correctly
mark "debug" shared objects.
In fact I just spoke with Nick Clifton about this in binutils, and it requires
we mark the "debug" shared objects to avoid this problem.
There is lots of tooling which needs to be updated to avoid loading "debug"
shared objects.
I'm reopening this bug and retitling.

I'd rather not define this concept for terminals. They cannot make a choice in
the sense client apps can.
Also for conciseness I'd reserve the word "app" or "application" for the client
app that's running inside the terminal emulator, and not the terminal emulator
itself in this discussion.

Nope. SHY-aware apps by definition never send SHY to the terminal, they either
send a regular hyphen U+2D or nothing at all, that's what makes them SHY-aware.
(Especially since in several fonts the glyph of SHY is empty, it looks like a
space.) If an app ever sends a SHY to the terminal emulator, it is SHY-unaware.
Hence for SHY-aware apps, wcwidth() of SHY is irrelevant.
For SHY-unaware ones it's important that what the application thinks will
happen matches with what really happens in the terminal emulator. Both the
application and the terminal emulator may or may not rely on wcwidth(), or the
app may even rely on wcwidth() of a remote system.

I'm not arguing against 1 at all. In fact, my guts feeling tell me to go with 1
rather than 0. I just wouldn't want 0 being ditched with invalid arguments.

There's no BiDi in VTE, anyway, I wouldn't want to pollute this bugreport with
this.

OK, granted, if that is the sense, you are, of course, correct.
(But that also means that, if it’s irrelevant for them, which,
again, if they send U+002D to the terminal instead, it is, then
all the more reason to stick to 1.)

Yes,that is really a good reason to stick to 1.

So it looks like we have reached some agreement that width 1 is OK
for the soft hypen and I can close this bug as FIXED, right?
Closing as FIXED.

Bug ID: 22140
Summary: ftell() returns incorrect value for memory stream
Product: glibc
Version: 2.27
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: tortoise_74 at yahoo dot co.uk
Target Milestone: ---
See
https://stackoverflow.com/questions/46229457/correct-semantics-for-ftell-when-used-on-a-memory-stream
Given the following program:
#include <stdio.h>
#include <stdlib.h>
#include <gnu/libc-version.h>
int main(void)
{
puts (gnu_get_libc_version ());
size_t n_buffer = 1024;
char *buffer = calloc(n_buffer, sizeof(char));
FILE *file = fmemopen(buffer, n_buffer, "w");
/* "ABCD" */
static const char magic_number[] =
{
0x41, 0x42, 0x43, 0x44
};
const size_t written = fwrite(magic_number, 1, 4, file);
fprintf(stderr,"written=%d\n",written);
int fstatus = fflush(file);
fprintf(stderr,"fstatus=%d\n",fstatus);
int ftellpos = ftell(file);
fprintf(stderr,"ftellpos=%d\n",ftellpos);
fstatus = fseek(file, 0, SEEK_END);
fprintf(stderr,"fstatus=%d\n",fstatus);
ftellpos = ftell(file);
fprintf(stderr,"ftellpos2=%d\n",ftellpos);
return 0;
}
The output on RHEL7 is:
2.17
written=4
fstatus=0
ftellpos=4
fstatus=0
ftellpos2=4
Whereas the output on OpenSUSE Leap 42 is:
2.22
written=4
fstatus=0
ftellpos=0
fstatus=0
ftellpos2=4
There are significant changes in fmemopen.c and fileop.c in those two versions
that probably explain the difference.
I believe ftell() ought to work as it does in 2.17 on RHEL7 and that the
version in 2.22 on OpenSUSE has a bug.
However, it could be that the bug is in the documentation which does not make
the relevant semantics for memory streams clear.

Bug ID: 22142
Summary: printf oupts a wrong value of DBL_MAX on ppc64 and
ppc64le
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: tuliom at linux dot vnet.ibm.com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Using the following program:
#include <stdio.h>
#include <float.h>
int main() {
printf("double max = %.8f \n", DBL_MAX);
printf("double max = %a \n", DBL_MAX);
return 0;
}
Outputs:
double max =

double max = 0x1.fffffffffffffp+1023
Instead of:
double max =

i386: Add _dl_runtime_resolve_shstk/_dl_runtime_profile_shstk [BZ #21598]
Add SHSTK compatible symbol resolvers to support Shadow Stack in Intel
Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
Replace _dl_runtime_resolve and _dl_runtime_profile with
_dl_runtime_resolve_shstk and _dl_runtime_profile_shstk, respectively if
SHSTK is enabled.
[BZ #21598]
* sysdeps/i386/dl-trampoline.S (_dl_runtime_resolve_shstk): New.
(_dl_runtime_profile_shstk): Likewise.
* sysdeps/unix/sysv/linux/i386/dl-cet.c: New file.

commit b9dc52912df0d6151e694452c46240bbf1e0d163
Author: H.J. Lu <hjl.tools@gmail.com>

x86: Support IBT and SHSTK in Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a CET-enabled compiler, CET is enabled by
default, unless --disable-cet is used to configure glibc. When CET is
enabled, both compiler and assembler must support CET. Otherwise, it
is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property.
* config.h.in (ENABLE_CET): New #undef.
* configure.ac: Add --enable-cet.
* configure: Regenerated.
* elf/dl-load.c (filebuf): Moved before "dynamic-link.h".
(_dl_map_object_from_fd): Call DL_PROCESS_PT_NOTE on PT_NOTE
segment if DL_PROCESS_PT_NOTE is defined.
* elf/rtld.c (dl_main): Likewise.
* elf/dl-support.c: Include <dl-procruntime.c>.
* include/link.h: Include <link_map.h>.

x86: Support IBT and SHSTK in Intel CET
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output
only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_IBT is
set on the executable, enable IBT.
2. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on
output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable, if GNU_PROPERTY_X86_FEATURE_1_SHSTK is
set on the executable as well as all shared objects loaded via the
DT_NEEDED tag, enable SHSTK.
2. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
When glibc is built with a CET-enabled compiler, CET is enabled by
default, unless --disable-cet is used to configure glibc. When CET is
enabled, both compiler and assembler must support CET. Otherwise, it
is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. The optional DL_PROCESS_PT_NOTE
is called to process PT_NOTE segment for GNU program property and
set l_cet.
b. _dl_start_user calls _dl_cet_init, instead of _dl_init, which sets
_dl_x86_feature_1 as well as sets up IBT and SHSTK.
3. For static executables, _dl_setup_cet is called to process PT_NOTE
segment for GNU program property to set _dl_x86_feature_1 as well as set
up IBT and SHSTK.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property.

[BZ #21745] powerpc: build some IFUNC math functions for libc and libm
Some math functions have to be distributed in libc because they're
required by printf.
libc and libm require their own builds of these functions, e.g. libc
functions have to call __stack_chk_fail_local in order to bypass the
PLT, while libm functions have to call __stack_chk_fail.
While math/Makefile treat the generic cases, i.e. s_isinff, the
multiarch Makefile has to treat its own files, i.e. s_isinff-ppc64.
[BZ #21745]
* sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile:
[$(subdir) = math] (sysdep_calls): New variable. Has the
previous contents of sysdep_routines, but re-sorted..
[$(subdir) = math] (sysdep_routines): Re-use the contents from
sysdep_calls.
[$(subdir) = math] (libm-sysdep_routines): Remove the functions
defined in sysdep_calls and replace by the respective m_* names.
* sysdeps/powerpc/powerpc64/fpu/multiarch/s_isnan-ppc64.S:
(compat_symbol): Undefine to avoid duplicated compat symbols in
libc.

I compiled ftp://ftp.gnu.org/gnu/glibc/glibc-2.26.tar.xz
with:
-linux-4.9.38
-gcc (GCC) 6.3.0
-GNU ld (GNU Binutils) 2.28
-GNU Awk 4.1.4
-perl 5, version 24, subversion 0 (v5.24.0)
-GNU Make 4.2.1
-libtool (GNU libtool) 2.4.6
for:
-i686-pc-linux-gnu
If I want to use the new glibc I get this error, too:
chroot /mnt/hdb5/SYS-2/
Inconsistency detected by ld.so: get-dynamic-info.h: 143: elf_get_dynamic_info:

I guess that 80% of all plans compiling glibc from source is to upgrade from a
8-12 years old system to a newest one. So this should be the default initial
position for developing glibc, binutils, ...

Bug ID: 22145
Summary: ttyname() gives up too early in the face of namespaces
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: lukeshu at sbcglobal dot net
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Commit 15e9a4f (which was the fix for #12167) introduced returning ENODEV for
when we can't determine the TTY's name because we inherited it from a different
mount namespace. However, just because the TTY is from a different namespace,
and we can no longer reach it at the original name doesn't mean its
unreachable. It shouldn't stop the old fallback iteration code from running;
that fallback might very well find the name.
For instance, systemd-nspawn arranges for the TTY to be at /dev/console, even
though it's original /dev/pts/X location won't be the same TTY. With glibc
2.25 this worked fine, but with 15e9a4f applied in 2.26, not so much:
$ sudo systemd-nspawn --register=no -D /path/to/my-container /bin/bash
Spawning container my-container on /path/to/my-container.
Press ^] three times within 1s to kill container.
bash: cannot set terminal process group (-1): Inappropriate ioctl for
device
bash: no job control in this shell
[root@my-container /]#
This is because the TTY, originally /dev/pts/${X}, is only available at
/dev/console in the new mount namespace. Bash gets the TTY on FD 0, and calls
ttyname(STDIN_FILENO). Before 15e9a4f, this correctly returned "/dev/console",
but now it returns NULL and sets errno=ENODEV.

proposed fix part 2
I've attached a pair of patches that I believe fixes this. In the morning I'll
test it (it's building now), and look in to including this in the test suite.
I guess I'll have to add a ChangeLog entry, and update my FSF assignment
paperwork to include libc.

Is there any reason it doesn't print 0x00000000 or such on a 32bit machine? I
expected it to just output 0x hex of the word size of the arch.

--- Comment #2 from bastl <bastl at eclipso dot de> ---
Like discribed in the INSTALL file and here:
https://sourceware.org/glibc/wiki/Testing/Builds
-Building glibc with intent to install
with:
./configure --prefix=/usr
and:
export DESTDIR=/mnt/hdb5/SYS-2
make
make check :breaks also with the chroot error
make install
I tried different things also LFS like.
Thank you!

Bug ID: 22146
Summary: C++ build issue with float128 on x86_64
Product: glibc
Version: 2.26
Status: UNCONFIRMED
Severity: critical
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: romain.naour at gmail dot com
Target Milestone: ---
Created attachment 10417
--> https://sourceware.org/bugzilla/attachment.cgi?id=10417&action=edit
patch disabling float128
Hi,
I'm trying to update to glibc 2.26 in Buildroot but I encounter the same build
issue with some C++ programs or libraries (mesa, kodi, jsoncpp for now).
Each issue can be fixed easily but this means that we can't use
"std::fpclassify" anymore.
See:
[mesa] http://patchwork.ozlabs.org/patch/809139/
[kodi] http://patchwork.ozlabs.org/patch/809146/
[jsoncpp] http://patchwork.ozlabs.org/patch/809144/
git bisect return the offending commit:
https://sourceware.org/git/?p=glibc.git;a=commit;h=c86ed71d633c22d6f638576f7660c52a5f783d66
As a workaround I disabled float128 on x86 and x86_64 and the C++ issue is
gone. But this is not a good solution...
I haven't find any bug report about this.
Can you have a look?
Best regards,
Romain Naour

Am I correct in my assessment that the test suite has no way to add tests that
require root access?

--- Comment #1 from romain.naour at gmail dot com ---
Adding some details for each packages:
mesa3d:
mesa is adding the following function from the std namespace to the global
namespace.
error: « std::fpclassify » was not declared in this scope
error: « std::isfinite » was not declared in this scope
error: « std::isinf » was not declared in this scope
error: « std::isnan » was not declared in this scope
error: « std::isnormal » was not declared in this scope
error: « std::signbit » was not declared in this scope
error: « std::isgreater » was not declared in this scope
error: « std::isgreaterequal » was not declared in this scope
error: « std::isless » was not declared in this scope
error: « std::islessequal » was not declared in this scope
error: « std::islessgreater » was not declared in this scope
error: « std::isunordered » was not declared in this scope
kodi:
kodi is using std::isnan in their code leading to the same build issue but with
a different error message.
error: '__builtin_isnan' is not a member of 'std'
jsoncpp:
Like for mesa and kodi, isfinite is used from the std namespace.
error: 'isfinite' is not a member of 'std'

On IRC, djdelorie made me aware of support_become_root(). I have verified that
the patches work. I'll get around to writing testcases eventually.

Okay, that should be valid.
The only explanation I have is that your link editor automatically adds an
RPATH for some reason. What's the output of “readelf -d elf/ld.so�

Patch of xdr.c ("xdr_char()" and "xdr_u_char()")
Here is a patch of the "xdr_char()" and "xdr_u_char()" functions based on the
behaviour of the other functions like "xdr_int()", "xdr_long()", etc.

Patches should be posted to the mailing list. The XDR_DECODE part seems to be
broken because it does not actually decode anything.

Bug ID: 22149
Summary: cache.c:save_cache creates zero-size VLA
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: schwab@linux-m68k.org
Target Milestone: ---
The C standard does not allow creating a VLA with zero size, but save_cache
tries to do so when the padding is zero. This causes misbehaviour with the
proposed -fstack-clash-protection option of gcc which assumes that it can
always emit at least one stack probe to the allocated space.

Hello Florian,
thank your for your reply!
I didn't know that about the mailing list. I'm a little bit confused why
patches should be posted there because if I want to add an atachment here there
is a patch checkbox...
But anyways, the patch I provided does not seem broken to me. The decoding
takes place by "*cp = u;" or "*cp = i;" in the "case XDR_DECODE:" block. It is
exactly like the other functions do that.
Further why you flag this as security?

Zero-length arrays are a documented GNU extension. This is a GCC bug.

Not sure whether this extension also applies to VLA, since the zero-length
array extension only talks about constant size, and gcc only documents to
extend the C99 VLAs to C90 and C++.

If someone has LD_RUN_PATH set in their environment, that would explain a

You'll have to raise this on the mailing list. I don't think we plan to change

(especially not on a bug which has been fixed some time ago).

--- Comment #3 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
Does not appear in results at
https://sourceware.org/glibc/wiki/Release/2.26#HPPA so presumably fixed by some
fma patch that postdated this bug report. My guess at the most likely to be
responsible is
commit 4896f049205013528f1f0df7f7cbb52e8c5664d1
Author: Richard Henderson <rth@twiddle.net>
Date: Fri Aug 1 12:13:50 2014 -1000
Force eval for fma implementations
but it could always be a different commit that did it.

--- Comment #3 from romain.naour at gmail dot com ---
Hi Joseph,
Yes, I'm using glibc 2.26 from the stable branch (commit
56ce01906ecb0a3e04411f8ceb60b27f4877f070).
Same for gcc 7.x (commit 56ce01906ecb0a3e04411f8ceb60b27f4877f070) and binutils
2.29.1 (commit b8440a913ad431f633aa1f5a4257418162cd4b7a).
Best regards,
Romain Naour

--- Comment #4 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
And to confirm: you built GCC against a version of glibc that included
those release branch fixes, not against an older 2.26 version? Because
the described symptom in bug 21930 was missing support for these C99
interfaces in libstdc++ when configured against a glibc version without
those fixes, which seems to match what you're seeing. (The std::
interfaces for C99 macros come from libstdc++, not glibc; glibc only
provides them for TS 18661-1 macros such as iszero and issignaling.)
What did the libstdc++ configure check "for ISO C99 support in <math.h>
for C++98" result in when you built your GCC? If it failed, you should
look in more detail at config.log from the libstdc++ build and see exactly
how the headers from current glibc 2.26 branch sources got expanded there.

Summary: setxid abort impossible to debug
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: peter.zelezny at dektech dot com.au
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 10422
--> https://sourceware.org/bugzilla/attachment.cgi?id=10422&action=edit
record 'error' into memory before abort()ing.
Hi,
I recently got an abort() inside allocatestack.c::__nptl_setxid_error().
Unfortunately it's impossible to see the last error from the syscall (from
kernel). It would be really invaluable to see this number, but it tends to be
optimized out into registers, which are then clobbered by abort() itself.
I suggest the newest 'error' is placed into the cmdp structure (into memory),
so that core dumps will contain this value.
Would something like this (patch attached) be reasonable to do?

Correct the size of _nl_value_type_LC_... arrays (v9)
This is the new series of patches, attempting to be prepared to the final
commit.
This patch is not directly related with this bug but necessary to be pushed
before the other patches. More related with bug 356. I was asked to split it
out. Previously these changes were included in the patch attached in the
comment 83.

Implement alternative month names (v9)
This patch merges everything related with adding the alternative month names:
nl_langinfo(ALTMON_…) and strftime("%OB"). At the same time it splits out the
changes from the previous comment and some automatically generated files.

Regenerate locfile-kw.h from locfile-kw.gperf (v9)
This patch contains changes to the automatically generated file split out from
the previous patch because I was asked not to post them to libc-locale mailing
list. But these changes still need to be pushed to the repository so I post
them here.

What will happen with other patches:
- backward compatibility patches most probably will be rejected, please ignore
for now,
- updates to the locale data: probably will be regenerated and pushed later,
for now please treat them as sample data necessary to actually use the newly
added features and see the difference.

Bug ID: 22156
Summary: [hppa,ia64,microblaze] Executable stack default
Product: glibc
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org

CC: drepper.fsp at gmail dot com
Target Milestone: ---
As per https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01220.html hppa, ia64 and
microblaze default to non-executable stacks in the Linux kernel. glibc however
defines DEFAULT_STACK_PERMS to include PF_X for those architectures, meaning
(a) elf/check-execstack fails and (b) (from code inspection, not tested, but
this is why I think this is a user-visible bug) thread stacks are unnecessarily
mapped with execute permission.

Summary: getcwd() returns EINVAL(22) instead of ENOENT
Product: glibc
Version: unspecified

Test Program and strace log
Hi,
Sometimes getcwd() returns EINVAL error instead of ENOENT.
I have come accross a scenario like below,
Under Test Program, mlockall(MCL_FUTURE) is called and after that repeatedly
getcwd(NULL, 66000) is called and "errno" is checked if getcwd() returns NULL.
Now, under script below steps are executed,
################
count=1
maxcount=999999
mkdir thr_getcwd_testdir/
cd thr_getcwd_testdir/
rm -rf ../thr_getcwd_testdir/
while [ $count -le $maxcount ];
do
../thr_getcwd ===>>> program which calls mlockall() and then getcwd(()
if [ "$?" != "0" ] ; then
exit 1
fi
done
################
Here, current directory is deleted but it's handle is still present.
What is expected is getcwd() should have set errno to ENOENT but errno
is set to EINVAL.
After going through the glibc code flow looks like below,
getcwd()
=> __getcwd() => malloc()
=> getcwd()[syscall] ---> This sets errno as ENOENT.
=> free() => __libc_free() => _int_free() => heap_trim()
=> shrink_heap() => __madvise()
=> madvise()[syscall] ---> This sets errno as EINVAL because of mlockall().
So eventhough getcwd() sets correct errono but madvise() changes that and due
to that application receives wrong errno.
Same is confirmed via strace, which is attached with the bug.
$ strace -f -o strace.txt ./thr_getcwd.sh
We have even attached Test Program to reproduce the issue.
Running test program,
$ tar -xzvf thr_getcwd.tgz
$ ./thr_getcwd.sh
Please suggest if above scenario should be considered as bug or not.
Thanks!
Dhiraj

Bug ID: 22159
Summary: Tests segfault on --enable-tunables=no
Product: glibc
Version: 2.27
Status: NEW
Severity: normal
Priority: P2
Component: malloc
Assignee: unassigned at sourceware dot org
Reporter: tuliom at linux dot vnet.ibm.com
Target Milestone: ---
The following tests are segfaulting when glibc is configured with
--enable-tunables=no:
FAIL: elf/tst-env-setuid
FAIL: malloc/tst-malloc-usable
FAIL: malloc/tst-malloc-usable-static
FAIL: malloc/tst-mcheck
I reproduced this issue on ppc, ppc64, ppc64le and x86_64.
I bisected these failures to:
commit ac3ed168d0c0b2b702319ac0db72c9b475a8c72e
Author: Florian Weimer <fweimer@redhat.com>
Date: Wed Aug 30 19:29:38 2017 +0200
malloc: Remove check_action variable [BZ #21754]
Clean up calls to malloc_printerr and trim its argument list.
This also removes a few bits of work done before calling
malloc_printerr (such as unlocking operations).
The tunable/environment variable still enables the lightweight
additional malloc checking, but mallopt (M_CHECK_ACTION)
no longer has any effect.

Hi,
I am also testing Romains patches in buildroot and tried them with
https://sourceware.org/git/?p=glibc.git;a=commit;h=2422c6032fd5e95b1c29df5b8671455ead51314e
today.
Quoting configure log of gcc-6.4.0:

It's a bug that free sets errno. Thanks for pointing out another scenario for
that.

--- Comment #6 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
The issue is the use of -Os to build libstdc++. Gabriel, it looks like
fpclassify needs a conditional as well to avoid the __MATH_TG version for (C++
and float128 support), for the same reason as isinf but only applicable when
-Os is used to build libstdc++.

--- Comment #7 from Gabriel F. T. Gomes <gabriel at inconstante dot eti.br> ---
For the record, this also applies to powerpc64le (and should apply to ia64 and
x86, as well, though I haven't checked on these platforms). However, since
compiler support for float128 is not enabled by default on powerpc64le (not
before GCC 8), this error will not be seen unless -mfloat128 is passed as a
compiler option to g++ (e.g.: CXXFLAGS=-mfloat128).
I'm working on a fix for glibc.

commit ae8372d7e4c44f6839aa3d851d4d0cb486b81cd5
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Sep 20 16:54:05 2017 +0000
Add SSE4.1 trunc, truncf (bug 20142).
This patch adds SSE4.1 versions of trunc and truncf, using the roundsd
/ roundss instructions, similar to the versions of ceil, floor, rint
and nearbyint functions we already have. In my testing with the glibc
benchtests these are about 30% faster than the C versions for double,
20% faster for float.
Tested for x86_64.
[BZ #20142]
* sysdeps/x86_64/fpu/multiarch/Makefile (libm-sysdep_routines):
Add s_trunc-c, s_truncf-c, s_trunc-sse4_1 and s_truncf-sse4_1.
* sysdeps/x86_64/fpu/multiarch/s_trunc-c.c: New file.
* sysdeps/x86_64/fpu/multiarch/s_trunc-sse4_1.S: Likewise.
* sysdeps/x86_64/fpu/multiarch/s_trunc.c: Likewise.
* sysdeps/x86_64/fpu/multiarch/s_truncf-c.c: Likewise.
* sysdeps/x86_64/fpu/multiarch/s_truncf-sse4_1.S: Likewise.
* sysdeps/x86_64/fpu/multiarch/s_truncf.c: Likewise.

That's nothing to do with float128. The obsolete X/Open isnan C function
isn't declared by glibc for C++, deliberately. That test is *meant* to
fail.
Look at the <cmath> and <math.h> installed with GCC - in locations such as
<target>/include/c++/7.2.1/math.h. The math.h header should include
<cmath> and then have various using declarations. The cmath header should
include directives such as "#undef fpclassify" (meaning that all these
math.h macros in glibc's math.h are completely irrelevant for C++). If
they don't, you need to trace back why the wrong versions of those headers
got installed by libstdc++ (compare configure results with an installation
built without --enable-target-optspace, for example). If the headers look
as expected, you need to trace the exact sequence of header inclusions,
macros defines and undefines seen in your C++ test, to see why the C
macros are visible for C++ when they should always be undefined by the C++
cmath header, which is included from the C++ version of math.h.
