Bug #: 14279
Summary: [2.15 backport] catch up on bugs fixed since 2.15
release
Product: glibc
Version: 2.15
Status: NEW
Keywords: glibc_2.15
Severity: normal
Priority: P2
Component: ports
AssignedTo: unassigned@sourceware.org
ReportedBy: cmetcalf@tilera.com
CC: carlos@systemhalted.org, roland@gnu.org
Classification: Unclassified
Since tile has not yet been supported in an official release, this bug is just
a placeholder for bug fixes that have been made in master during the runup to
the 2.16 release. The seven correctness bugs that have been fixed should be
backported to 2.15. (Cleanup, performance bugs, and purely test-support
changes don't, I think, rise to the level of being necessary to backport.)

linux-generic: add wordsize-32 version of prlimit64/fanotify syscalls

tile: allow memcpy(p, p, n) without corrupting memory at "p"
Although this is not required by the definition of memcpy(),
in practice this sort of thing does happen, and it's easy to make
the code robust by doing nothing in this case. (Since structure
copy causes the compiler to emit a memcpy, in the case where the
target structure is the same as the destination, we were seeing
corruption.)

tile: fix bug in CFI definitions for clone.S
We were missing a critical cfi_def_cfa_offset call in .Lthread_start
which caused backtracing to get badly confused for threads.

tile: add include <features.h> to <sys/dataplane.h>
We were using __BEGIN_DECLS without <features.h> and it just happened
to mostly work, but of course we should include it here.

tile: align stack for tilegx32
Previously we weren't re-aligning the stack pointer during the
call to _dl_init(), so for tilegx32 and an odd value in _dl_skip_args
and kernel unaligned access fixups disabled, we would die with SIGBUS.
We now handle this case properly by aligning before calling _dl_init().

Chris,
Could you attach the patch to this issue?
I can review the patch and OK you to check it into the stable 2.15 branch?

Chris,
Please split this into at *least* 2 commits, one for tile changes, one for
linux-generic changes.
OK to commit to 2.15 stable branch with those changes (and the expectation of
no new regressions in the testsuite).

I think we're actually fine. The changes in my repository for 2.15 are seven
commits, cherry picked in the usual way. I haven't merged them into a single
commit or anything like that, and I was planning to push them as 7 commits,
including the "(cherry picked from commit blah blah)" lines in the commit
messages.
I haven't tested any platforms other than tilepro, tilegx64, and tilegx32, but
these changes aren't seen by any other platforms (yet - perhaps more to come
with linux-generic, but not yet that I know of).
Let me know if this sounds like what you were expecting :-)

That rationale is exactly what I was expecting, and sound good.
Please commit to 2.15 branch.

As this was approved, you should commit it to the branch and close the bug as
fixed....
