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.

Short description: Add C.UTF-8 support.
Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>
Origin: PATCH
Upstream status: not-submitted
This patch needs to upstream as part of Carlos O'Donell
<carlos@redhat.com>'s work on enabling upstream C.UTF-8 support. This
work is currently blocked on cleaning up the test results to prove that
full code-point sorting is working as intended.
Note that this patch does not provide full code-point sorting as
expected.
This patch needs to upstream as soon as possible since it would be nice
to have this in F29 and fixed.

__get_nprocs which returns a the system available online CPU.
The Linux implementation currently only calls __get_nprocs(), which
in tuns calls sched_getaffinity.

Patch proposed for upstream inclusion:
<https://sourceware.org/pipermail/libc-alpha/2021-September/130802.html>

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.

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
Author: Florian Weimer <fweimer@redhat.com>
Date: Mon Sep 13 11:06:08 2021 +0200
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>
Date: Mon Sep 13 11:06:08 2021 +0200
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.

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.

Date: Fri Aug 6 09:51:38 2021 +0200
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.
Fixes commit 8a40aff86ba5f64a3a84883e539cb67b ("io: Add time64 alias
for fcntl"), commit 82c395d91ea4f69120d453aeec398e30 ("misc: Add
time64 alias for ioctl"), commit b39ffab860cd743a82c91946619f1b8158

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.
