__NR_futex isn't avaliable on newer 32-bit architectures (such as RV32)
so if it isn't avaliable lets use __NR_futex_time64 instead.

The nanosleep syscall is not supported on newer 32-bit platforms (such
as RV32). To fix this issue let's change to using clock_nanosleep_time64
instead.

Let's use CLOCK_REALTIME when calling clock_nanosleep_time64 as the
Linux specification says:
  "POSIX.1 specifies that nanosleep() should measure time against the
   CLOCK_REALTIME clock. However, Linux measures the time using the
   CLOCK_MONOTONIC clock. This probably does not matter, since the POSIX.1
   specification for clock_settime(2) says that discontinuous changes in
   CLOCK_REALTIME should not affect nanosleep()"

* [RFC v1 00/16]  RISC-V glibc port for the 32-bit

This patch set contains the glibc port for the 32-bit RISC-V.

This is based on all of the work that Zong Li has done [1].

I have taken the latest branch from Zong Li and rebased it onto master.
I added a single GCC8.2 fix into one of his patches, otherwise the
patches are the same as his but rebased on master.

Unfortunately the Linux ABI has changed since Zong Li's latest
submission. The RISC-V 32-bit (RV32) ABI no longer defines
__ARCH_WANT_TIME32_SYSCALLS which means there are no 32-bit versions of
time_t, off_t or any struct resource or system calls that use them.

To mitigate this I have set the RV32 port to use 64-bit time_t and off_t
(as is done in x86-32) and also changed the syscall imvocation to handle
the missing syscalls. Patches 1 to 5 are generic ways of handling the
missing syscall functions. Patch 7 changes all RISC-V implementations to
use 64-bit time_t and off_t.

I have tested this series by building a buildroot kernel and rootFS
using these glibc patches and an upstream 5.1.12 kernel for RV32.

Patch 4 (waitid) seems to cause hangs that I haven't debugged yet, it
seems like we aren't handing the wait() functions correctly.

The last patch is a hack to forcefully rename the remaining system calls
that are causing compiller failures to the 64-bit versions. This is
obviously not the correct way to do this. I would like some feedback on
this series to find the upstream approved way to use the 64-bit
versions.

Feedback on this series is very welcome!

For the recommand of 64 bit version, we add the libraries path of 32 bit
in this patch. This includes a fix to avoid an out of bound array check
when building with GCC 8.2.

2018-11-29  Zong Li  <zong@andestech.com>

	* sysdeps/unix/sysv/linux/riscv/dl-cache.h (add_system_dir): Add
	libraries path for rv32.

Not all architectures support the obsolete gettimeofday so use the
newer clock_gettime64 syscall. This fixes RV32 build issues.

Using the original glibc headers under bits/ let's make small
modifications to use 64-bit time_t and off_t for both RV32 and RV64.

From: Zong Li <zongbox@gmail.com>

Similar to the recent fix for MIPS, ARM and S/390, RV32 is missing
correct exception on overflow from llrint and llround functions because
cast from floating-point types to long long do not result in correct
exceptions on overflow.

If the __NR_waitid syscall is avaliable let's use that as __NR_waitpid
and __NR_wait4 aren't always avaliable (they aren't avaliable on RV32).

Sorry, how is this supposed to work for all the other architectures
which don't have this system call with current kernel versions?

Good question, I'm sure it doesn't.

If we put this around #if defined(clock_nanosleep_time64) or #ifndef
clock_nanosleep and then keep the current code as the #else would that
be acceptable to upstream?

The main goal of this RFC series was to get feedback if this is in the
right direction, or maybe I'm just missing something much simpler.

Does this work in <sysdep.h> for the port?

#define __NR_clock_nanosleep  __NR_clock_nanosleep_time64

This is somewhat hackish, but it's reasonably accurate for architectures
that provide standard system calls under non-standard names for some
reason.

Obviously, this assume that for these new ports, the UAPI headers do the
right thing and use 64-bit time_t for the old structs as well.

Thanks,
Florian

I'm at home today so I can't check, but I suspect that will work.

For the RV32 case I think this will provide a workable solution. I am
under the impression though that all 32-bit architectures are
eventually removing __ARCH_WANT_TIME32_SYSCALLS from Linux so they
will also hit this issue. Which is why I was going for a more generic
approach. In saying that, whatever gets the RV32 port in works for me
:)

AFAIK they should be, at least in this case.

Fairly sure you want __SYSCALL_SLONG_TYPE to be __SWORD_TYPE
not __SQUAD_TYPE here. Only x86/x32 is special here.

However, rlim_t, ino_t and off_t are all 64-bit and match their *64_t
counterparts, so drop the #ifdef here.

Generally speaking we never remove system calls from the kernel, rv32
was the exception to this rule because there was no upstream C library
port. __ARCH_WANT_TIME32_SYSCALLS will probably hang around for
shortly before year 2038 -- afterwards there is no point any more as all
binaries relying on it will be broken then.

We will however allow building kernels that omit the time32 syscalls
before then, as they are only adding baggage to the kernel size and
make it harder to verify that user space doesn't try calling them.

I think for internal libc functions, you need to try both functions:
first the time64 version for kernels that leave out the 32-bit one,
and then the time32 version for running on pre-5.1 kernels.

For user-visible glibc interfaces (e.g. nanosleep()), user space with
a 64-bit time_t will have to try the time64 syscall first and then fall
back on the time32 version for pre-5.1 kernels, while user space
with 32-bit time_t should only call the old time32 syscall and fail
on any kernel that doesn't support that, either because
__ARCH_WANT_TIME32_SYSCALLS is not set at compile
time, or because the kernel was configured without these.

Why is this file architecture specific? It seems everything else just uses
#include <sysdeps/unix/sysv/linux/i386/lockf64.c>
Is your code different from that version?

This breaks all other 32-bit architectures, since glibc traditionally uses
32-bit limits even on architectures that always supported the 64-bit
interface.

If we just mask out the high bits will that fix the problem?

Ok, so if I re-jig the series to #ifdef the 64-bit syscall first and
then fall back to the standard (32-bit) syscall that will be the
correct solution?

Ok, so this seems to just be changing the #ifdef logic to something like this:

#ifdef time_t == 64
# ifdef __NR_syscall64
    __NR_syscall64()
# else
    __NR_syscall()
# endif
#else /* time_t == 64*/
    __NR_syscall()
#endif

Although that just simplifies to:

# ifdef __NR_syscall64
    __NR_syscall64()
# else
    __NR_syscall()
# endif

I don't know, I didn't change or look too deeply into these patches.
I'll check when I'm at work tomorrow.

As part of the code review it was indicated that we shouldn't #include C files
but should instead duplicate them.  At the time it was exactly the same, we
should scrutinize any differences as that was months ago.

I would expect that you would want it to be consistent across architectures
as well: so either replace all the other #include versions with direct copies,
or move the file into a more generic location that avoids the #include if you
can't add another one any more.

Kernel seems to allow builds with disabled time32 syscalls and if it were indeed 
used on deployments we will need to do change the glibc implementation to do:

--
#ifdef __NR_syscall64
  long int ret = __NR_syscall64 ();
  if (ret == 0 || errno != ENOSYS)
    return ret;
#endif
  return __NR_syscall ();
--

We can optimize by adding __ASSUME macros on kernel-features to explicit make 
syscall64 is always used, which will turn to previous logic to:

--
#ifdef __ASSUME_syscall64
  return __NR_syscall64 ();
#else
# ifdef __NR_syscall64
  long int ret = __NR_syscall64 ();
  if (ret == 0 || errno != ENOSYS)
    return ret;
# endif
  return __NR_syscall ();
#endif

Since e442e40de5646e93bf31ace3e0c5159085a7259b glibc lock{64} is based on
fcntl{64}.  And sysdeps/unix/sysv/linux/fcntl{64}.c should already call
__NR_fcntl64 for the required cases.  So why do you need to add an arch
specific lock64 implementation here?

Ok, so it sounds like the correct solution is to do the above
#ifdef-ing for all the problematic syscalls. I'll do that and send an
v2.

Yep, this isn't required any more, I have removed it.

Neither of these work as in this case __NR_syscall() isn't defiend. We
can't include it at all for glibc to compile.

I get some strange compiler errors if I do that, it looks like the
offset into some structures don't line up (I don't have the log handy
unfortunately).

Here's the original review, for context:
https://marc.info/?l=glibc-alpha&m=151407510809658&w=2 .  As far as I
understand it, the goal here was explicitly to avoid shared code.  I'd be happy
to change this tree wide if it's OK with everyone else, as I generally dislike
code duplication.

The following are general comments that I think are still applicable to 
the current version.

See <https://sourceware.org/glibc/wiki/NewPorts>.  A lot of things in 
there are inapplicable for this case (architecture variant for an existing 
port), but some *are* applicable.  For example, you're using GLIBC_2.29 
symbol versions, which is wrong; the versions have to be those of the 
first release to have the new port (so GLIBC_2.31 or later).  As another 
example, you need to include details of test results when submitting a new 
port.

Build on top of the Y2038 series, helping to fix the issues with that 
series so it can get in sooner.  In general, get to a state before adding 
this port where each time-related function, for which you think you might 
need changes for RV32, is implemented following the pattern where the main 
implementation is for 64-bit times and the version for 32-bit times is a 
thin wrapper round that, unless there is a good, well-commented reason to 
do otherwise, and then you're much less likely to need further changes for 
RV32.

Other architectures using binary128 long double don't have such large ULPs 
here.  You need to explain why you're getting larger ULPs for RV32.  
Likewise for the other ULPs increases.  If necessary, trace execution of 
the functions both on RV32 and on some other architecture (e.g. AArch64, 
or x86_64 for the _Float128 functions) to determine exactly where it 
diverges.

Maybe there is some relevant soft-fp bug, beyond the one that was fixed by

commit ff48ea6787526d7e669af93ce2681b911d39675c
Author: Zong Li <zong@andestech.com>
Date:   Thu Nov 1 17:34:39 2018 +0000

    soft-fp: Use temporary variable in FP_FRAC_SUB_3/FP_FRAC_SUB_4

(of course you need to make sure the GCC you use has that fix in libgcc as 
well)?
