commit 1d8e3a2c6636cf0b1b8fa2f869cef6ec10726933

localedef: Fix handling of empty mon_decimal_point (Bug 28847)
The handling of mon_decimal_point is incorrect when it comes to
handling the empty "" value. The existing parser in monetary_read()
will correctly handle setting the non-wide-character value and the
wide-character value e.g. STR_ELEM_WC(mon_decimal_point) if they are
set in the locale definition. However, in monetary_finish() we have
conflicting TEST_ELEM() which sets a default value (if the locale
definition doesn't include one), and subsequent code which looks for
mon_decimal_point to be NULL to issue a specific error message and set
the defaults. The latter is unused because TEST_ELEM() always sets a
default. The simplest solution is to remove the TEST_ELEM() check,
and allow the existing check to look to see if mon_decimal_point is
NULL and set an appropriate default. The final fix is to move the
setting of mon_decimal_point_wc so it occurs only when
mon_decimal_point is being set to a default, keeping both values
consistent. There is no way to tell the difference between
mon_decimal_point_wc having been set to the empty string and not
having been defined at all, for that distinction we must use
mon_decimal_point being NULL or "", and so we must logically set
the default together with mon_decimal_point.
Lastly, there are more fixes similar to this that could be made to
ld-monetary.c, but we avoid that in order to fix just the code
required for mon_decimal_point, which impacts the ability for C.UTF-8
to set mon_decimal_point to "", since without this fix we end up with
an inconsistent setting of mon_decimal_point set to "", but
mon_decimal_point_wc set to "." which is incorrect.
Tested on x86_64 and i686 without regression.

commit de82cb0da4b8fa5b3d56c457438d2568c67ab1b1
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Oct 12 13:48:39 2021 +0000
Add TEST_COMPARE_STRING_WIDE to support/check.h
I'd like to be able to test narrow and wide string interfaces, with
the narrow string tests using TEST_COMPARE_STRING and the wide string
tests using something analogous (possibly generated using macros from
a common test template for both the narrow and wide string tests where
appropriate).
Add such a TEST_COMPARE_STRING_WIDE, along with functions
support_quote_blob_wide and support_test_compare_string_wide that it
builds on. Those functions are built using macros from common
templates shared by the narrow and wide string implementations, though
I didn't do that for the tests of test functions. In
support_quote_blob_wide, I chose to use the \x{} delimited escape
sequence syntax proposed for C2X in N2785, rather than e.g. trying to
generate the end of a string and the start of a new string when
ambiguity would result from undelimited \x (when the next character
after such an escape sequence is valid hex) or forcing an escape
sequence to be used for the next character in the case of such
ambiguity.
Tested for x86_64.

commit 7e0ad15c0fbfe25435c1acd0ed3e9cedfbff2488
Author: Carlos O'Donell <carlos@redhat.com>
Date: Mon Jan 31 00:34:42 2022 -0500
localedata: Adjust C.UTF-8 to align with C/POSIX.
We have had one downstream report from Canonical [1] that
an rrdtool test was broken by the differences in LC_TIME
that we had in the non-builtin C locale (C.UTF-8). If one
application has an issue there are going to be others, and
so with this commit we review and fix all the issues that
cause the builtin C locale to be different from C.UTF-8,
which includes:
* mon_decimal_point should be empty e.g. ""
- Depends on mon_decimal_point_wc fix.
* negative_sign should be empty e.g. ""
* week should be aligned with the builtin C/POSIX locale
* d_fmt corrected with escaped slashes e.g. "%m//%d//%y"
* yesstr and nostr should be empty e.g. ""
* country_ab2 and country_ab3 should be empty e.g. ""
We bump LC_IDENTIFICATION version and adjust the date to
indicate the change in the locale.
A new tst-c-utf8-consistency test is added to ensure
consistency between C/POSIX and C.UTF-8.
Tested on x86_64 and i686 without regression.

commit e09e7b1492b2d5c2f68ddf81f8f58e093dd4df6d
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Mon Dec 13 11:36:42 2021 -0300
support: Add support_socket_so_timestamp_time64
Check if the socket support 64-bit network packages timestamps
(SO_TIMESTAMP and SO_TIMESTAMPNS). This will be used on recvmsg
and recvmmsg tests to check if the timestamp should be generated.

commit e098446037da532d4a250efac9a813bc22f3669f
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>

linux: Fix ancillary 64-bit time timestamp conversion (BZ #28349, BZ#28350)
The __convert_scm_timestamps only updates the control message last
pointer for SOL_SOCKET type, so if the message control buffer contains
multiple ancillary message types the converted timestamp one might
overwrite a valid message.
The test checks if the extra ancillary space is correctly handled
by recvmsg/recvmmsg, where if there is no extra space for the 64-bit
time_t converted message the control buffer should be marked with
MSG_TRUNC. It also check if recvmsg/recvmmsg handle correctly multiple
ancillary data.
Checked on x86_64-linux and on i686-linux-gnu on both 5.11 and
4.15 kernel.

commit 489d0b8b32548bc569cd3067aebf98b030720753
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Jan 27 16:45:18 2022 -0300
Linux: Only generate 64 bit timestamps for 64 bit time_t recvmsg/recvmmsg
The timestamps created by __convert_scm_timestamps only make sense for
64 bit time_t programs, 32 bit time_t programs will ignore 64 bit time_t
timestamps since SO_TIMESTAMP will be defined to old values (either by
glibc or kernel headers).
Worse, if the buffer is not suffice MSG_CTRUNC is set to indicate it
(which breaks some programs [1]).
This patch makes only 64 bit time_t recvmsg and recvmmsg to call
__convert_scm_timestamps. Also, the assumption to called it is changed
from __ASSUME_TIME64_SYSCALLS to __TIMESIZE != 64 since the setsockopt
might be called by libraries built without __TIME_BITS=64. The
MSG_CTRUNC is only set for the 64 bit symbols, it should happen only
if 64 bit time_t programs run older kernels.
Checked on x86_64-linux-gnu and i686-linux-gnu.

tst-socket-timestamp-compat.c: Check __TIMESIZE [BZ #28837]
time_t size is defined by __TIMESIZE, not __WORDSIZE. Check __TIMESIZE,
instead of __WORDSIZE, for time_t size. This fixes BZ #28837.

x86: Fix __wcsncmp_avx2 in strcmp-avx2.S [BZ# 28755]
Fixes [BZ# 28755] for wcsncmp by redirecting length >= 2^56 to
__wcscmp_avx2. For x86_64 this covers the entire address range so any
length larger could not possibly be used to bound `s1` or `s2`.
test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass.

commit 948ebc098ed3cd928ea10997f990115e7770bda3
Author: Florian Weimer <fweimer@redhat.com>
Date: Thu Jan 27 16:03:58 2022 +0100
Fix glibc 2.34 ABI omission (missing GLIBC_2.34 in dynamic loader)
The glibc 2.34 release really should have added a GLIBC_2.34
symbol to the dynamic loader. With it, we could move functions such
as dlopen or pthread_key_create that work on process-global state
into the dynamic loader (once we have fixed a longstanding issue
with static linking). Without the GLIBC_2.34 symbol, yet another
new symbol version would be needed because old glibc will fail to
load binaries due to the missing symbol version in ld.so that newly
linked programs will require.
