89dc0372a9 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.

2738480a4b 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.

66016ec8ae 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.

466f2be6c0 Add generic C.UTF-8 locale (Bug 17318)
We add a new C.UTF-8 locale. This locale is not builtin to glibc, but
is provided as a distinct locale. The locale provides full support for
UTF-8 and this includes full code point sorting via STRCMP-based
collation (strcmp or wcscmp).

The collation uses a new keyword 'codepoint_collation' which drops all
collation rules and generates an empty zero rules collation to enable
STRCMP usage in collation. This ensures that we get full code point
sorting for C.UTF-8 with a minimal 1406 bytes of overhead (LC_COLLATE
structure information and ASCII collating tables).

The new locale is added to SUPPORTED. Minimal test data for specific
code points (minus those not supported by collate-test) is provided in
C.UTF-8.in, and this verifies code point sorting is working reasonably
across the range. The locale was tested manually with the full set of
code points without failure.

The locale is harmonized with locales already shipping in various
downstream distributions. A new tst-iconv9 test is added which verifies
the C.UTF-8 locale is generally usable.

Testing for fnmatch, regexec, and recomp is provided by extending
bug-regex1, bugregex19, bug-regex4, bug-regex6, transbug, tst-fnmatch,
tst-regcomp-truncated, and tst-regex to use C.UTF-8.

Tested on x86_64 or i686 without regression.

f5117c6504 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.

30891f35fa Remove "Contributed by" lines
We stopped adding "Contributed by" or similar lines in sources in 2012
in favour of git logs and keeping the Contributors section of the
glibc manual up to date.  Removing these lines makes the license
header a bit more consistent across files and also removes the
possibility of error in attribution when license blocks or files are
copied across since the contributed-by lines don't actually reflect
reality in those cases.

Move all "Contributed by" and similar lines (Written by, Test by,
etc.) into a new file CONTRIBUTED-BY to retain record of these
contributions.  These contributors are also mentioned in
manual/contrib.texi, so we just maintain this additional record as a
courtesy to the earlier developers.

The following scripts were used to filter a list of files to edit in
place and to clean up the CONTRIBUTED-BY file respectively.  These
were not added to the glibc sources because they're not expected to be
of any use in future given that this is a one time task:

224edada60 configure: Allow LD to be LLD 13.0.0 or above [BZ #26558]
When using LLD (LLVM linker) as the linker, configure prints a confusing
message.

    *** These critical programs are missing or too old: GNU ld

LLD>=13.0.0 can build glibc --enable-static-pie. (8.0.0 needs one

--disable-static-pie).

XFAIL two tests sysdeps/x86/tst-ifunc-isa-* which have the BZ #28154

The set of dynamic symbols is the same with GNU ld and LLD,
modulo unused SHN_ABS version node symbols.

For comparison, gold does not support --enable-static-pie
yet (--no-dynamic-linker is unsupported BZ #22221), yet
has 6 failures more than LLD. gold linked libc.so has
larger .dynsym differences with GNU ld and LLD
(non-default version symbols are changed to default versions
by a version script BZ #28196).

0835c0f0ba x86: fix Autoconf caching of instruction support checks [BZ #27991]
The Autoconf documentation for the AC_CACHE_CHECK macro states:

  The commands-to-set-it must have no side effects except for setting
  the variable cache-id, see below.

However, the tests for support of -msahf and -mmovbe were embedded in
the commands-to-set-it for lib_cv_include_x86_isa_level. This had the
consequence that libc_cv_have_x86_lahf_sahf and libc_cv_have_x86_movbe
were not defined whenever lib_cv_include_x86_isa_level was read from
cache. These variables' being undefined meant that their unquoted use
in later test expressions led to the 'test' built-in's misparsing its
arguments and emitting errors like "test: =: unexpected operator" or
"test: =: unary operator expected", depending on the particular shell.

This commit refactors the tests for LAHF/SAHF and MOVBE instruction
support into their own AC_CACHE_CHECK macro invocations to obey the
rule that the commands-to-set-it must have no side effects other than
setting the variable named by cache-id.

6e8a0aac2f time: Fix overflow itimer tests on 32-bit systems
On the port of OpenRISC I am working on and it appears the rv32 port
we have sets __TIMESIZE == 64 && __WORDSIZE == 32.  This causes the
size of time_t to be 8 bytes, but the tv_sec in the kernel is still 32-bit
causing truncation.

The truncations are unavoidable on these systems so skip the
testing/failures by guarding with __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64.

Also, futher in the tests and in other parts of code checking for time_t
overflow does not work on 32-bit systems when time_t is 64-bit.  As
suggested by Adhemerval, update the in_time_t_range function to assume
32-bits by using int32_t.

This also brings in the header for stdint.h so we can update other
usages of __int32_t to int32_t as suggested by Adhemerval.

0f62fe0532 mips: increase stack alignment in clone to match the ABI
In "mips: align stack in clone [BZ #28223]"
(commit 1f51cd9a86) 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].

[1]: "System V Application Binary Interface: MIPS(R) RISC Processor
      Supplement, 3rd edition", page 3-31
[2]: "MIPSpro(TM) 64-Bit Porting and Transition Guide", page 23

1f51cd9a86 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.

4cc79c2177 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.
