commit f5117c6504888fab5423282a4607c552b90fd3f9
Author: Carlos O'Donell <carlos@redhat.com>
Date: Thu Jul 29 22:45:39 2021 -0400
Add 'codepoint_collation' support for LC_COLLATE.
Support a new directive 'codepoint_collation' in the LC_COLLATE
section of a locale source file. This new directive causes all
collation rules to be dropped and instead STRCMP (strcmp or
wcscmp) is used for collation of the input character set. This
is required to allow for a C.UTF-8 that contains zero collation
rules (minimal size) and sorts using code point sorting.
To date the only implementation of a locale with zero collation
rules is the C/POSIX locale. The C/POSIX locale provides
identity tables for _NL_COLLATE_COLLSEQMB and
_NL_COLLATE_COLLSEQWC that map to ASCII even though it has zero
rules. This has lead to existing fnmatch, regexec, and regcomp
implementations that require these tables. It is not correct
to use these tables when nrules == 0, but the conservative fix
is to provide these tables when nrules == 0. This assures that
existing static applications using a new C.UTF-8 locale with
'codepoint_collation' at least have functional range expressions
with ASCII e.g. [0-9] or [a-z]. Such static applications would
not have the fixes to fnmatch, regexec and regcomp that avoid
the use of the tables when nrules == 0. Future fixes to fnmatch,
regexec, and regcomp would allow range expressions to use the
full set of code points for such ranges.
Tested on x86_64 and i686 without regression.

In Fedora we should return only /usr/bin because /bin is just a symlink
to /usr/bin after MoveToUsr transition (which glibc has not really

Short description: Fedora-specific workaround for kernel pty bug.
Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>
Origin: PATCH
Upstream status: not-submitted
This is a Fedora-specific workaround for a kernel bug where calling
ioctl on a pty will silently ignore the invalid c_cflag. The
workaround is to use TCGETS to verify the setting matches. This is
not upstream and needs to either be removed or submitted upstream
after analysis.

Short description: Place glibc info into "Libraries" category.
Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>
Origin: PATCH
Upstream status: not-needed
The category names for libraries is completely random including
"Libraries", "GNU Libraries", "GNU libraries", and "Software libraries."
In the GNU info manual the "Software libraries" category is given as an
example, but really we need to standardize on a category for upstream.
I suggest we drop this change after some upstream discussion.

MIPS: Setup errno for {f,l,}xstat
{f,l,}xstat stub for MIPS is using INTERNAL_SYSCALL
to do xstat syscall for glibc ver, However it leaves
errno untouched and thus giving bad errno output.
Setup errno properly when syscall returns non-zero.

commit 3abf3bd4edc86fb28c099cc85203cb46a811e0b8

nptl: pthread_kill, pthread_cancel should not fail after exit (bug 19193)
This closes one remaining race condition related to bug 12889: if
the thread already exited on the kernel side, returning ESRCH
is not correct because that error is reserved for the thread IDs
(pthread_t values) whose lifetime has ended. In case of a
kernel-side exit and a valid thread ID, no signal needs to be sent
and cancellation does not have an effect, so just return 0.
sysdeps/pthread/tst-kill4.c triggers undefined behavior and is
removed with this commit.

commit a8ac8c4725ddb1119764126a8674a04c9dd5aea8
Author: Florian Weimer <fweimer@redhat.com>

nptl: Fix race between pthread_kill and thread exit (bug 12889)
A new thread exit lock and flag are introduced. They are used to
detect that the thread is about to exit or has exited in
__pthread_kill_internal, and the signal is not sent in this case.
The test sysdeps/pthread/tst-pthread_cancel-select-loop.c is derived
from a downstream test originally written by Marek Polacek.

iconvconfig: Fix behaviour with --prefix [BZ #28199]
The consolidation of configuration parsing broke behaviour with
--prefix, where the prefix bled into the modules cache. Accept a
prefix which, when non-NULL, is prepended to the path when looking for
configuration files but only the original directory is added to the
modules cache.
This has no effect on the codegen of gconv_conf since it passes NULL.

commit ae925404a10bf0ea63d6e8d41e3821f68b4d776c
Author: Aurelien Jarno <aurelien@aurel32.net>
Date: Fri Sep 3 00:28:14 2021 +0200
Fix failing nss/tst-nss-files-hosts-long with local resolver
When a local resolver like unbound is listening on the IPv4 loopback
address 127.0.0.1, the nss/tst-nss-files-hosts-long test fails. This is
due to:
- the default resolver in the absence of resolv.conf being 127.0.0.1
- the default DNS NSS database configuration in the absence of
nsswitch.conf being 'hosts: dns [!UNAVAIL=return] file'
This causes the requests for 'test4' and 'test6' to first be sent to the
local resolver, which responds with NXDOMAIN in the likely case those
records do no exist. In turn that causes the access to /etc/hosts to be
skipped, which is the purpose of that test.
Fix that by providing a simple nsswitch.conf file forcing access to
/etc/hosts for that test. I have tested that the only changed result in
the testsuite is that test.

commit 005bafcf5b8a85d4c82831401f052747e160a7e8
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Sep 8 12:42:06 2021 +0000
Update syscall lists for Linux 5.14
Linux 5.14 has two new syscalls, memfd_secret (on some architectures
only) and quotactl_fd. Update syscall-names.list and regenerate the
arch-syscall.h headers with build-many-glibcs.py update-syscalls.
Tested with build-many-glibcs.py.

Update kernel version to 5.14 in tst-mman-consts.py
This patch updates the kernel version in the test tst-mman-consts.py
to 5.14. (There are no new MAP_* constants covered by this test in
5.14 that need any other header changes.)
Tested with build-many-glibcs.py.

Add MADV_POPULATE_READ and MADV_POPULATE_WRITE from Linux 5.14 to bits/mman-linux.h
Linux 5.14 adds constants MADV_POPULATE_READ and MADV_POPULATE_WRITE
(with the same values on all architectures). Add these to glibc's
bits/mman-linux.h.
Tested for x86_64.

posix: Fix attribute access mode on getcwd [BZ #27476]
There is a GNU extension that allows to call getcwd(NULL, >0). It is
described in the documentation, but also directly in the unistd.h
header, just above the declaration.
Therefore the attribute access mode added in commit 06febd8c6705
is not correct. Drop it.

nptl: pthread_kill needs to return ESRCH for old programs (bug 19193)
The fix for bug 19193 breaks some old applications which appear
to use pthread_kill to probe if a thread is still running, something
that is not supported by POSIX.

support: Add support_open_dev_null_range
It returns a range of file descriptor referring to the '/dev/null'
pathname. The function takes care of restarting the open range
if a file descriptor is found within the specified range and
also increases RLIMIT_NOFILE if required.
Checked on x86_64-linux-gnu.

commit 772e33411bc730f832f415f93eb3e7c67e4d5488
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Tue Aug 24 16:15:50 2021 -0300
Use support_open_dev_null_range io/tst-closefrom, misc/tst-close_range, and posix/tst-spawn5 (BZ #28260)
It ensures a continuous range of file descriptor and avoid hitting
the RLIMIT_NOFILE.
Checked on x86_64-linux-gnu.

nptl: Avoid setxid deadlock with blocked signals in thread exit [BZ #28361]
As part of the fix for bug 12889, signals are blocked during
thread exit, so that application code cannot run on the thread that
is about to exit. This would cause problems if the application
expected signals to be delivered after the signal handler revealed
the thread to still exist, despite pthread_kill can no longer be used
to send signals to it. However, glibc internally uses the SIGSETXID
signal in a way that is incompatible with signal blocking, due to the
way the setxid handshake delays thread exit until the setxid operation
has completed. With a blocked SIGSETXID, the handshake can never
complete, causing a deadlock.
As a band-aid, restore the previous handshake protocol by not blocking
SIGSETXID during thread exit.
The new test sysdeps/pthread/tst-pthread-setuid-loop.c is based on
a downstream test by Martin Osvald.

support: Add check for TID zero in support_wait_for_thread_exit
Some kernel versions (observed with kernel 5.14 and earlier) can list
"0" entries in /proc/self/task. This happens when a thread exits
while the task list is being constructed. Treat this entry as not
present, like the proposed kernel patch does:

nptl: pthread_kill must send signals to a specific thread [BZ #28407]
The choice between the kill vs tgkill system calls is not just about
the TID reuse race, but also about whether the signal is sent to the
whole process (and any thread in it) or to a specific thread.
This was caught by the openposix test suite:
LTP: openposix test suite - FAIL: SIGUSR1 is member of new thread pendingset.

misc: Add __get_nprocs_sched
This is an internal function meant to return the number of avaliable
processor where the process can scheduled, different than the
__get_nprocs which returns a the system available online CPU.
The Linux implementation currently only calls __get_nprocs(), which
in tuns calls sched_getaffinity.

linux: Simplify get_nprocs
This patch simplifies the memory allocation code and uses the sched
routines instead of reimplement it. This still uses a stack
allocation buffer, so it can be used on malloc initialization code.
Linux currently supports at maximum of 4096 cpus for most architectures:
$ find -iname Kconfig | xargs git grep -A10 -w NR_CPUS | grep -w range
arch/alpha/Kconfig- range 2 32
arch/arc/Kconfig- range 2 4096
arch/arm/Kconfig- range 2 16 if DEBUG_KMAP_LOCAL
arch/arm/Kconfig- range 2 32 if !DEBUG_KMAP_LOCAL
arch/arm64/Kconfig- range 2 4096
arch/csky/Kconfig- range 2 32
arch/hexagon/Kconfig- range 2 6 if SMP
arch/ia64/Kconfig- range 2 4096
arch/mips/Kconfig- range 2 256
arch/openrisc/Kconfig- range 2 32
arch/parisc/Kconfig- range 2 32
arch/riscv/Kconfig- range 2 32
arch/s390/Kconfig- range 2 512
arch/sh/Kconfig- range 2 32
arch/sparc/Kconfig- range 2 32 if SPARC32
arch/sparc/Kconfig- range 2 4096 if SPARC64
arch/um/Kconfig- range 1 1
arch/x86/Kconfig-# [NR_CPUS_RANGE_BEGIN ... NR_CPUS_RANGE_END] range.
arch/x86/Kconfig- range NR_CPUS_RANGE_BEGIN NR_CPUS_RANGE_END
arch/xtensa/Kconfig- range 2 32
With x86 supporting 8192:
arch/x86/Kconfig
976 config NR_CPUS_RANGE_END
977 int
978 depends on X86_64
979 default 8192 if SMP && CPUMASK_OFFSTACK
980 default 512 if SMP && !CPUMASK_OFFSTACK
981 default 1 if !SMP
So using a maximum of 32k cpu should cover all cases (and I would
expect once we start to have many more CPUs that Linux would provide
a more straightforward way to query for such information).
A test is added to check if sched_getaffinity can successfully return
with large buffers.
Checked on x86_64-linux-gnu and i686-linux-gnu.

linux: Revert the use of sched_getaffinity on get_nproc (BZ #28310)
The use of sched_getaffinity on get_nproc and
sysconf (_SC_NPROCESSORS_ONLN) done in 903bc7dcc2acafc40 (BZ #27645)
breaks the top command in common hypervisor configurations and also
other monitoring tools.
The main issue using sched_getaffinity changed the symbols semantic
from system-wide scope of online CPUs to per-process one (which can
be changed with kernel cpusets or book parameters in VM).
This patch reverts mostly of the 903bc7dcc2acafc40, with the
exceptions:
* No more cached values and atomic updates, since they are inherent
racy.
* No /proc/cpuinfo fallback, since /proc/stat is already used and
it would require to revert more arch-specific code.
* The alloca is replace with a static buffer of 1024 bytes.
So the implementation first consult the sysfs, and fallbacks to procfs.
Checked on x86_64-linux-gnu.

Suppress -Wcast-qual warnings in bsearch
The first cast to (void *) is redundant but should be (const void *)
anyway, because that's the type of the lvalue being assigned to.
The second cast is necessary and intentionally not const-correct, so
tell the compiler not to warn about it.

Add missing braces to bsearch inline implementation [BZ #28400]
GCC treats the pragma as a statement, so that the else branch only
consists of the pragma, not the return statement.

Linux: Fix fcntl, ioctl, prctl redirects for _TIME_BITS=64 (bug 28182)
__REDIRECT and __THROW are not compatible with C++ due to the ordering of the
__asm__ alias and the throw specifier. __REDIRECT_NTH has to be used
instead.

librt: fix NULL pointer dereference (bug 28213)
Helper thread frees copied attribute on NOTIFY_REMOVED message
received from the OS kernel. Unfortunately, it fails to check whether
copied attribute actually exists (data.attr != NULL). This worked
earlier because free() checks passed pointer before actually
attempting to release corresponding memory. But
__pthread_attr_destroy assumes pointer is not NULL.
So passing NULL pointer to __pthread_attr_destroy will result in
segmentation fault. This scenario is possible if
notification->sigev_notify_attributes == NULL (which means default
thread attributes should be used).

librt: add test (bug 28213)
This test implements following logic:
1) Create POSIX message queue.
Register a notification with mq_notify (using NULL attributes).
Then immediately unregister the notification with mq_notify.
Helper thread in a vulnerable version of glibc
should cause NULL pointer dereference after these steps.
2) Once again, register the same notification.
Try to send a dummy message.
Test is considered successfulif the dummy message
is successfully received by the callback function.

# Auto-generating dependencies for glibc development snapshots.
#
# A glibc development snapshot (say version 2.33.9000) may define
# symbols in its under-development symbol version (GLIBC_2.34). RPM
# automatically derives RPM dependencies such as
# libc.so.6(GLIBC_2.34)(64bit) from that. While the GLIBC_2.34
# version is under development, these dependencies may be inaccurate
# and could be satisfied by glibc RPM package versions that lack the
# symbols because they were created from an earlier development
# snapshot that had some other GLIBC_2.34 symbols. Therefore, if the
# latest, under-development ELF symbol version is detected, this
# dependency generator adds an explicit RPM dependencies on the glibc
# packaging version against which an RPM package is built.
