commit 7af07fe795f43e53d31be1c6f9adba7e05f87b0b

mips: align stack in clone [BZ #28223]
The MIPS O32 ABI requires 4 byte aligned stack, and the MIPS N64 and N32
ABI require 8 byte aligned stack. Previously if the caller passed an
unaligned stack to clone the the child misbehaved.
Fixes bug 28223.

mips: increase stack alignment in clone to match the ABI
In "mips: align stack in clone [BZ #28223]"
(commit 1f51cd9a860ee45eee8a56fb2ba925267a2a7bfe) I made a mistake: I
misbelieved one "word" was 2-byte and "doubleword" should be 4-byte.
But in MIPS ABI one "word" is defined 32-bit (4-byte), so "doubleword" is
8-byte [1], and "quadword" is 16-byte [2].

commit 93aabf891e96e93f100081ee07989c23d7107d17

arm: Guard ucontext _rtld_global_ro access by SHARED, not PIC macro
Due to PIE-by-default, PIC is now defined in more cases. libc.a
does not have _rtld_global_ro, and statically linking setcontext
fails. SHARED is the right condition to use, so that libc.a
references _dl_hwcap instead of _rtld_global_ro.
For static PIE support, the !SHARED case would still have to be made
PIC. This patch does not achieve that.
Fixes commit 23645707f12f2dd9d80b51effb2d9618a7b65565
("Replace --enable-static-pie with --disable-default-pie").

commit dc9b69d5331dcdca4547c0490cb9fefbd89e40f6

nss: Use "files dns" as the default for the hosts database (bug 28700)
This matches what is currently in nss/nsswitch.conf. The new ordering
matches what most distributions use in their installed configuration
files.
It is common to add localhost to /etc/hosts because the name does not
exist in the DNS, but is commonly used as a host name.
With the built-in "dns [!UNAVAIL=return] files" default, dns is
searched first and provides an answer for "localhost" (NXDOMAIN).
We never look at the files database as a result, so the contents of
/etc/hosts is ignored. This means that "getent hosts localhost"
fail without a /etc/nsswitch.conf file, even though the host name
is listed in /etc/hosts.

elf: Fix tst-cpu-features-cpuinfo for KVM guests on some AMD systems [BZ #28704]
On KVM guests running on some AMD systems, the IBRS feature is reported
as a synthetic feature using the Intel feature, while the cpuinfo entry
keeps the same. Handle that by first checking the presence of the Intel
feature on AMD systems.
Fixes bug 28704.

powerpc64[le]: Allocate extra stack frame on syscall.S
The syscall function does not allocate the extra stack frame for scv like other
assembly syscalls using DO_CALL_SCV. So after commit d120fb9941 changed the
offset that is used to save LR, syscall ended up using an invalid offset,
causing regressions on powerpc64. So make sure the extra stack frame is
allocated in syscall.S as well to make it consistent with other uses of
DO_CALL_SCV and avoid similar issues in the future.
Tested on powerpc, powerpc64, and powerpc64le (with and without scv)

This fixes the misc/tst-misalign-clone-internal and
misc/tst-misalign-clone tests.

Linux: Fix 32-bit vDSO for clock_gettime on powerpc32
When the clock_id is CLOCK_PROCESS_CPUTIME_ID or CLOCK_THREAD_CPUTIME_ID,
on the 5.10 kernel powerpc 32-bit, the 32-bit vDSO is executed successfully (
because the __kernel_clock_gettime in arch/powerpc/kernel/vdso32/gettimeofday.S
does not support these two IDs, the 32-bit time_t syscall will be used),
but tp32.tv_sec is equal to 0, causing the 64-bit time_t syscall to continue to be used,
resulting in two system calls.
Fix commit 72e84d1db22203e01a43268de71ea8669eca2863.

intl/plural.y: Avoid conflicting declarations of yyerror and yylex
bison-3.8 includes these lines in the generated intl/plural.c:
#if !defined __gettexterror && !defined YYERROR_IS_DECLARED
void __gettexterror (struct parse_args *arg, const char *msg);
#endif
#if !defined __gettextlex && !defined YYLEX_IS_DECLARED
int __gettextlex (YYSTYPE *yylvalp, struct parse_args *arg);
#endif
Those default prototypes provided by bison conflict with the
declarations later on in plural.y. This patch solves the issue.

timezone: handle truncated timezones from tzcode-2021d and later (BZ #28707)
When using a timezone file with a truncated starting time,
generated by the zic in IANA tzcode-2021d a.k.a. tzlib-2021d
(also in tzlib-2021e; current as of this writing), glibc
asserts in __tzfile_read (on e.g. tzset() for this file) and
you may find lines matching "tzfile.c:435: __tzfile_read:
Assertion `num_types == 1' failed" in your syslog.
One example of such a file is the tzfile for Asuncion
generated by tzlib-2021e as follows, using the tzlib-2021e zic:
"zic -d DEST -r @1546300800 -L /dev/null -b slim
SOURCE/southamerica". Note that in its type 2 header, it has
two entries in its "time-types" array (types), but only one
entry in its "transition types" array (type_idxs).
This is valid and expected already in the published RFC8536, and
not even frowned upon: "Local time for timestamps before the
first transition is specified by the first time type (time type
0)" ... "every nonzero local time type index SHOULD appear at
least once in the transition type array". Note the "nonzero ...
index". Until the 2021d zic, index 0 has been shared by the
first valid transition but with 2021d it's separate, set apart
as a placeholder and only "implicitly" indexed. (A draft update
of the RFC mandates that the entry at index 0 is a placeholder
in this case, hence can no longer be shared.)
* time/tzfile.c (__tzfile_read): Don't assert when no transitions
are found.

powerpc: Fix unrecognized instruction errors with recent GCC
Recent binutils commit b25f942e18d6ecd7ec3e2d2e9930eb4f996c258a
changes the behavior of `.machine` directives to override, rather
than augment, the base CPU. This can result in _reduced_ functionality
when, for example, compiling for default machine "power8", but explicitly
asking for ".machine power5", which loses Altivec instructions.
In tst-ucontext-ppc64-vscr.c, while the instructions provoking the new
error messages are bracketed by ".machine power5", which is ostensibly
Power ISA 2.03 (POWER5), the POWER5 processor did not support the
VSX subset, so these instructions are not recognized as "power5".
Error: unrecognized opcode: `vspltisb'
Error: unrecognized opcode: `vpkuwus'
Error: unrecognized opcode: `mfvscr'
Error: unrecognized opcode: `stvx'
Manually adding the VSX subset via ".machine altivec" is sufficient.

Update syscall lists for Linux 5.15
Linux 5.15 has one new syscall, process_mrelease (and also enables the
clone3 syscall for RV32). It also has a macro __NR_SYSCALL_MASK for
Arm, which is not a syscall but matches the pattern used for syscall
macro names.
Add __NR_SYSCALL_MASK to the names filtered out in the code dealing
with syscall lists, update syscall-names.list for the new syscall and
regenerate the arch-syscall.h headers with build-many-glibcs.py
update-syscalls.
Tested with build-many-glibcs.py.

commit 2fe2af88abd13ae5636881da2e26f461ecb7dfb5
Author: Florian Weimer <fweimer@redhat.com>
Date: Thu Jan 13 14:59:29 2022 +0100
i386: Remove broken CAN_USE_REGISTER_ASM_EBP (bug 28771)
The configure check for CAN_USE_REGISTER_ASM_EBP tried to compile a
simple function that uses %ebp as an inline assembly operand. If
compilation failed, CAN_USE_REGISTER_ASM_EBP was set 0, which
eventually had these consequences:
(1) %ebx was avoided as an inline assembly operand, with an
assembler macro hack to avoid unnecessary register moves.
(2) %ebp was avoided as an inline assembly operand, using an
out-of-line syscall function for 6-argument system calls.
(1) is no longer needed for any GCC version that is supported for
building glibc. %ebx can be used directly as a register operand.
Therefore, this commit removes the %ebx avoidance completely. This
avoids the assembler macro hack, which turns out to be incompatible
with the current Systemtap probe macros (which switch to .altmacro
unconditionally).
(2) is still needed in many build configurations. The existing
configure check cannot really capture that because the simple function
succeeds to compile, while the full glibc build still fails.
Therefore, this commit removes the check, the CAN_USE_REGISTER_ASM_EBP
macro, and uses the out-of-line syscall function for 6-argument system
calls unconditionally.
