acb55dcb89 Update Linux kernel version in tst-mman-consts.py.
This patch updates the Linux kernel version in tst-mman-consts.py to
4.20 (meaning that's the version for which glibc is expected to have
the same constants as the kernel, up to the exceptions listed in the
test).  (Once we have more such tests sharing common infrastructure, I
expect the kernel version will be something set in the infrastructure
shared by all such tests, rather than something needing updating
separately for each test for each new kernel version.)

Tested with build-many-glibcs.py.

fe20bb1d60 ARM: fix kernel assisted atomics with GCC 8 (bug 24034)
The pre-ARMv7 CPUs are missing atomic compare and exchange and/or
barrier instructions. Therefore those are implemented using kernel
assistance, calling a kernel function at a specific address, and passing
the arguments in the r0 to r4 registers. This is done by specifying
registers for local variables. The a_ptr variable is placed in the r2
register and declared with __typeof (mem). According to the GCC
documentation on local register variables, if mem is a constant pointer,
the compiler may substitute the variable with its initializer in asm
statements, which may cause the corresponding operand to appear in a
different register.

This happens in __libc_start_main with the pointer to the thread counter
for static binaries (but not the shared ones):

  # ifdef SHARED
        unsigned int *ptr = __libc_pthread_functions.ptr_nthreads;
  #  ifdef PTR_DEMANGLE
        PTR_DEMANGLE (ptr);
  #  endif
  # else
        extern unsigned int __nptl_nthreads __attribute ((weak));
        unsigned int *const ptr = &__nptl_nthreads;
  # endif

This causes static binaries using threads to crash when the GNU libc is
built with GCC 8 and most notably tst-cancel21-static.

To fix that, use the same trick than for the volatile qualifier,
defining a_ptr as a union.

Changelog:
	[BZ #24034]
	* sysdeps/unix/sysv/linux/arm/atomic-machine.h
	(__arm_assisted_compare_and_exchange_val_32_acq): Use uint32_t rather
	than __typeof (...) for the a_ptr variable.

2d9837c1fb Set behavior of sprintf-like functions with overlapping source and destination
According to ISO C99, passing the same buffer as source and destination
to sprintf, snprintf, vsprintf, or vsnprintf has undefined behavior.
Until the commit

  commit 4e2f43f842
  Author: Zack Weinberg <zackw@panix.com>
  Date:   Wed Mar 7 14:32:03 2018 -0500

      Use PRINTF_FORTIFY instead of _IO_FLAGS2_FORTIFY (bug 11319)

a call to sprintf or vsprintf with overlapping buffers, for instance
vsprintf (buf, "%sTEXT", buf), would append `TEXT' into buf, while a
call to snprintf or vsnprintf would override the contents of buf.
After the aforementioned commit, the behavior of sprintf and vsprintf
changed (so that they also override the contents of buf).

This patch reverts this behavioral change, because it will likely break
applications that rely on the previous behavior, even though it is
undefined by ISO C.  As noted by Szabolcs Nagy, this is used in SPEC2017
507.cactuBSSN_r/src/PUGH/PughUtils.c:

  sprintf(mess,"  Size:");
  for (i=0;i<dim+1;i++)
  {
      sprintf(mess,"%s %d",mess,pughGH->GFExtras[dim]->nsize[i]);
  }

More important to notice is the fact that the overwriting of the
destination buffer is not the only behavior affected by the refactoring.
Before the refactoring, sprintf and vsprintf would use _IO_str_jumps,
whereas __sprintf_chk and __vsprintf_chk would use _IO_str_chk_jumps.
After the refactoring, all use _IO_str_chk_jumps, which would make
sprintf and vsprintf report buffer overflows and terminate the program.
This patch also reverts this behavior, by installing the appropriate
jump table for each *sprintf functions.

Apart from reverting the changes, this patch adds a test case that has
the old behavior hardcoded, so that regressions are noticed if something
else unintentionally changes the behavior.

Tested for powerpc64le.

b50dd3bc8c malloc: Always call memcpy in _int_realloc [BZ #24027]
This commit removes the custom memcpy implementation from _int_realloc
for small chunk sizes.  The ncopies variable has the wrong type, and
an integer wraparound could cause the existing code to copy too few
elements (leaving the new memory region mostly uninitialized).
Therefore, removing this code fixes bug 24027.

<asm/syscalls.h> has been removed by

    riscv: add asm/unistd.h UAPI header

    Marcin Juszkiewicz reported issues while generating syscall table for riscv
    using 4.20-rc1. The patch refactors our unistd.h files to match some other
    architectures.

    - Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit
    - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h
    - Adjust kernel asm/unistd.h

    So now asm/unistd.h UAPI header should show all syscalls for riscv.

<asm/syscalls.h> may be restored by

Subject: [PATCH] riscv: restore asm/syscalls.h UAPI header
Date: Tue, 11 Dec 2018 09:09:35 +0100

UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header,
which did resolve issue with missing syscalls macros resulting in
glibc (2.28) build failure. It also broke glibc in a different way:
asm/syscalls.h is being used by glibc. I noticed this while doing
Fedora 30/Rawhide mass rebuild.

The patch returns asm/syscalls.h header and incl. it into asm/unistd.h.
I plan to send a patch to glibc to use asm/unistd.h instead of
asm/syscalls.h

In the meantime, we use __has_include__, which was added to GCC 5, to
check if <asm/syscalls.h> exists before including it.  Tested with
build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7.

989182c40a Multiple locales: Use the correct 12-hour time formats (bug 10496).
It has been discovered that some locales use the 12-hour time formats but
do not use any AM/PM indicator thus making the time ambiguous.  This
commit adds "%p" wherever it was missing.  In some cases it has been
identified that a locale should use 24-hour time format rather than
12-hour.  All time formats come from CLDR but this commit introduces as
few changes as possible (for example, it tries not to change the time zone
display).  For the locales which are not supported by CLDR the consistency
with similar locales (which means the same language or the same country)
has been preserved: if the time formats were the same before the change
then they are still the same after the change.

The time format updates can be roughly summarized as follows:

* Most of the locales of Djibouti, Eritrea, and Ethiopia now use
"%l:%M:%S %p".
* Most of the locales of India and some surrounding countries (Bangladesh,
Nepal etc.) now use "%I:%M:%S %p %Z".
* Most of the Arabic locales now use "%Z %I:%M:%S %p".
* Ge'ez language (Eritrea and Ethiopia) now uses "%l:%M:%S፡%p" (note the
consistent use of Ethiopic wordspace character).
* Tamil (India) now uses "%p %I:%M:%S %Z".
* Chinese (Hong Kong) t_fmt now uses "%p %I<U6642>%M<U5206>%S<U79D2> %Z".
* Additionally, the following locales have been switched from 12-hour time
formats to 24-hour, according to CLDR: Arabic (Morocco), Maltese, Somali
(Kenya), and Tamil (Sri Lanka).
* Finally, the Bulgarian, Czech, and Slovak locales used 24-hour time
format correctly but their t_fmt_ampm field was not empty containing
12-hour time format which was incorrect so it is now replaced with an
empty string.

27841a7d5a sq_AL: Use the correct date and time formats (bug 10496, 23724).
Albanian locale uses the 12-hour clock but some time formats did not
use any AM/PM indicator making the time ambiguous.  This commit adds
"%p" wherever it was missing.

It also sets the correct date format because the old "%Y-%b-%d" produced
rather weird results like "2018-Sht-28".

All time formats come from CLDR but as few changes have been introduced
by this commit as possible.  Some articles from MSDN and other available
online sources have been also taken into account.

57b3ff8e1a Update nios2, sparc32 localplt.data for difftime changes (bug 24023).
The recent difftime changes introduced localplt test failures on nios2
and sparc32, two configurations where some soft-fp functions are
defined in / exported from libc.so, and where the difftime changes
affected the particular set of floating-point operations used in
libc.so.  This patch adds those functions to localplt.data, alongside
other such functions already there.  (In the sparc32 case, and more
generally on any platform where long double is a software
floating-point type, it would probably be more efficient to avoid
using long double at all in difftime, but that's a pre-existing
issue.)

Tested with build-many-glibcs.py for its nios2 and sparcv9
configurations.

	[BZ #24023]
	* sysdeps/unix/sysv/linux/nios2/localplt.data: Allow __floatundidf
	PLT reference in libc.so.
	* sysdeps/unix/sysv/linux/sparc/sparc32/localplt.data: Allow
	_Q_lltoq and _Q_qtod PLT references in libc.so.

5d025ea617 Update longlong.h.
This patch updates longlong.h from GCC.  There were no local changes
in glibc (the previous version was identical to the r232143 GCC
version, apart from copyright dates which had been updated in both
places), so this patch makes it identical to the version in GCC again.

Tested for x86_64 and x86.  Also tested with build-many-glibcs.py for
its RISC-V configurations, as the glibc architecture with the most
substantial changes in longlong.h in this patch.

	* stdlib/longlong.h: Update from GCC.

192963be49 Require GCC 5 or later to build glibc (bug 23993).
We know that building glibc with GCC 4.9 is broken on various
platforms (bug 23993).  As it's more than a year since we last
increased the minimum GCC version to build glibc, this patch changes
the requirement to be GCC 5 or later (indeed, based on 4.9 having been
required for building 2.26, it would be consistent in terms of timing
to require GCC 6 or later from the 2.30 release onwards).  It
deliberately just updates the configure test and corresponding
documentation, leaving removal of no-longer-needed __GNUC_PREREQ tests
for a separate patch.

In the NEWS entry, the requirement for a newer GCC version for
powerpc64le is reiterated (as in the entry for the 4.9 requirement in
2.26) to avoid suggesting the version requirement there has gone down.
(If that version goes up further as part of support for binary128 long
double, of course the wording would change at that time.)

Tested for x86_64.

	[BZ #23993]
	* configure.ac (libc_cv_compiler_ok): Require GCC 5 or later.
	* configure: Regenerated.
