The changes introduce a memory leak for gconv steps arrays whose
first element is an internal conversion, which has a fixed
reference count which is not decremented. As a result, after the
change in commit 50ce3eae5b, the steps
array is never freed, resulting in an unbounded memory leak.
This reverts commit 50ce3eae5b
("gconv: Check reference count in __gconv_release_cache
[BZ #24677]") and commit 7e740ab2e7
("libio: Fix gconv-related memory leak [BZ #24583]"). It
reintroduces bug 24583. (Bug 24677 was just a regression caused by
the second commit.)
Commit ffe8a9a831, "powerpc: Remove
rt_sigreturn usage on context function", removed from powerpc32
swapcontext a setting of r31 that is relied upon in subsequent code.
I'm not sure why this didn't produce test failures in Adhemerval's
32-bit testing; in my (soft-float) testing in preparation for 2.30
release, I see several context-related failures
FAIL: stdlib/tst-makecontext2
FAIL: stdlib/tst-makecontext3
FAIL: stdlib/tst-setcontext

FAIL: stdlib/tst-setcontext4

that did not appear in 2.29 testing. This patch restores the removed
register setting in question, and thus fixes those failures.
Tested for powerpc (soft-float).
* sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S
(__CONTEXT_FUNC_NAME): Restore setting of r31.
Recent GCC versions warn about the attempt to return the address of a
local variable:
tst-pthread-getattr.c: In function ‘allocate_and_test’:
tst-pthread-getattr.c:54:10: error: function returns address of local variable [-Werror=return-local-addr]
54 | return mem;
| ^~~
In file included from ../include/alloca.h:3,
from tst-pthread-getattr.c:26:
../stdlib/alloca.h:35:23: note: declared here
35 | # define alloca(size) __builtin_alloca (size)
| ^~~~~~~~~~~~~~~~~~~~~~~
tst-pthread-getattr.c:51:9: note: in expansion of macro ‘alloca’
51 | mem = alloca ((size_t) (mem - target));
| ^~~~~~
The address itself is used in a check in the caller, so using
uintptr_t instead is reasonable.
Commit 35e038c1d2 started to use an
incomplete list of subdirs based on $(all-subdirs) causing
testroot.pristine to miss files from nss.
Tested if the list of files in testroot.pristine remains the same.
[BZ #24794]
* Makeconfig (all-subdirs): Improved source comments.
* Makefile (testroot.pristine/install.stamp): Pass
subdirs='$(sorted-subdirs)' to make install.
This fixes a regression introduced in commit
7e740ab2e7 ("libio: Fix gconv-related
memory leak [BZ #24583]").
__gconv_release_cache is only ever called with heap-allocated
arrays which contain at least one member. The statically allocated
ASCII steps are filtered out by __wcsmbs_close_conv.
When compiled with -O3 and AVX, GCC 8 and 9 optimize some loops in
sysdeps/ieee754/dbl-64/branred.c with 256-bit vector instructions,
which leads to store forward stall:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90579
There is no easy fix in compiler. This patch limits vector width to
128 bits to work around this issue. It improves performance of sin
and cos by more than 40% on Skylake compiled with -O3 -march=skylake.
Tested with GCC 7/8/9 on x86-64.
[BZ #24603]
* sysdeps/x86_64/configure.ac: Check if -mprefer-vector-width=128
works.
* sysdeps/x86_64/configure: Regenerated.
* sysdeps/x86_64/fpu/Makefile (CFLAGS-branred.c): New. Set
to -mprefer-vector-width=128 if supported.
The kernel changes for a 64-bit time_t on 32-bit architectures
resulted in <asm/socket.h> indirectly including <linux/posix_types.h>.
The latter is not namespace-clean for the POSIX version of
<sys/socket.h>.
This issue has persisted across several Linux releases, so this commit
creates our own copy of the SO_* definitions for !__USE_MISC mode.
The new test socket/tst-socket-consts ensures that the copy is
consistent with the kernel definitions (which vary across
architectures). The test is tricky to get right because CPPFLAGS
includes include/libc-symbols.h, which in turn defines _GNU_SOURCE
unconditionally.
Tested with build-many-glibcs.py. I verified that a discrepancy in
the definitions actually results in a failure of the
socket/tst-socket-consts test.
Whenever a sub-make is created, it inherits the variable subdirs from its
parent. This is also true when make check is called with a restricted
list of subdirs. In this scenario, make install is executed "partially"
and testroot.pristine ends up with an incomplete installation.
[BZ #24794]
* Makefile (testroot.pristine/install.stamp): Pass
subdirs='$(all-subdirs)' to make install.

Some DSOs are distributed in hardware capability directories, e.g.
/usr/lib64/power7/libc.so.6
Whenever the processor is able to use one of these hardware-enabled
DSOs, testroot.pristine ends up with copies of glibc-provided libraries
from the system because it can't overwrite or remove them.
This patch avoids the unintended copies by executing ld.so with the same
arguments passed to each glibc test.
* Makefile (testroot.pristine/install.stamp): Execute ld.so with
the same arguments used in all tests.

aarch64: new ifunc resolver ABI
See the commit log and the comments in sys/ifunc.h for details.
This patch adds Cyrillic to plain ASCII transliteration table according
to GOST 7.79-2000 System B standard to the C locale.
[BZ #2872]
* locale/C-translit.h.in: Add Cyrillic transliteration.
The pthread _clock functions that were recently added to nptl need to be
declared in hppa's pthread.h too. After this change, the function
declaration part of sysdeps/nptl/pthread.h and
sysdeps/unix/sysv/linux/hppa/pthread.h are identical.
* sysdeps/unix/sysv/linux/hppa/pthread.h: Add declarations of
functions recently added to sysdeps/nptl/pthread.h:
pthread_mutex_clocklock, pthread_rwlock_clockrdlock,
pthread_rwlock_clockwrlock and pthread_cond_clockwait.

In afe4de7d28, I added forwarding functions
from libc to libpthread for __pthread_cond_clockwait and
pthread_cond_clockwait to mirror those for pthread_cond_timedwait. These
are unnecessary[1], since these functions aren't (yet) being called from
within libc itself. Let's remove them.
* nptl/forward.c: Remove unnecessary __pthread_cond_clockwait and
pthread_cond_clockwait forwarding functions. There are no internal
users, so it is unnecessary to expose these functions in libc.so.
* sysdeps/nptl/pthread-functions.h (pthread_functions): Remove
unnecessary ptr___pthread_cond_clockwait member.
* nptl/nptl-init.c (pthread_functions): Remove assignment of
removed member.

This commit updates month and weekday names (full and abbreviated)
from CLDR 35.1 with the following exceptions.
It was not clear why the full name of February in aa_DJ and aa_ER was
"Kudo" while the abbreviated version is "Nah" but some additional
sources [1] [2] as well as the content of aa_ER and aa_ER@saaho
suggest it should be "Naharsi Kudo". This commit consequently sets
the translation of February to "Naharsi Kudo" in aa_DJ and aa_ET.
aa_ER@saaho is not supported by CLDR but since the month names were
identical to aa_ER before this commit, the same values have been copied
from aa_ER.
