nss: Implement --no-addrconfig option for getent
The ahosts, ahostsv4, ahostsv6 commands unconditionally pass
AI_ADDRCONFIG to getaddrinfo, which is not always desired.

Author: Florian Weimer <fweimer@redhat.com>
Date: Tue Sep 13 16:11:40 2022 +0200
nss: Fix tst-nss-files-hosts-long on single-stack hosts (bug 24816)
getent implicitly passes AI_ADDRCONFIG to getaddrinfo by default.
Use --no-addrconfig to suppress that, so that both IPv4 and IPv6
lookups succeed even if the address family is not supported by the
host.

elf: Do not completely clear reused namespace in dlmopen (bug 29600)
The data in the _ns_debug member must be preserved, otherwise
_dl_debug_initialize enters an infinite loop. To be conservative,
only clear the libc_map member for now, to fix bug 29528.
Fixes commit d0e357ff45a75553dee3b17ed7d303bfa544f6fe
("elf: Call __libc_early_init for reused namespaces (bug 29528)"),
by reverting most of it.

commit ca5df795459b9242cd7d787ebf71a09be2244577

linux: Fix generic struct_stat for 64 bit time (BZ# 29657)
The generic Linux struct_stat misses the conditionals to use
bits/struct_stat_time64_helper.h in the __USE_TIME_BITS64 for
architecture that uses __TIMESIZE == 32 (currently csky and nios2).
Since newer ports should not support 32 bit time_t, the generic
implementation should be used as default.
For arm, hppa, and sh a copy of default struct_stat is added,
while for csky and nios a new one based on generic is used, along
with conditionals to use bits/struct_stat_time64_helper.h.
The default struct_stat is also replaced with the generic one.
Checked on aarch64-linux-gnu and arm-linux-gnueabihf.

Makerules: fix MAKEFLAGS assignment for upcoming make-4.4 [BZ# 29564]
make-4.4 will add long flags to MAKEFLAGS variable:
* WARNING: Backward-incompatibility!
Previously only simple (one-letter) options were added to the MAKEFLAGS
variable that was visible while parsing makefiles. Now, all options
are available in MAKEFLAGS.
This causes locale builds to fail when long options are used:
$ make --shuffle
...
make -C localedata install-locales
make: invalid shuffle mode: '1662724426r'
The change fixes it by passing eash option via whitespace and dashes.
That way option is appended to both single-word form and whitespace
separated form.
While at it fixed --silent mode detection in $(MAKEFLAGS) by filtering
out --long-options. Otherwise options like --shuffle flag enable silent
mode unintentionally. $(silent-make) variable consolidates the checks.
Resolves: BZ# 29564

mktime: improve heuristic for ca-1986 Indiana DST
This patch syncs mktime.c from Gnulib, fixing a
problem reported by Mark Krenz <https://bugs.gnu.org/48085>,
and it should fix BZ#29035 too.
* time/mktime.c (__mktime_internal): Be more generous about
accepting arguments with the wrong value of tm_isdst, by falling
back to a one-hour DST difference if we find no nearby DST that is
unusual. This fixes a problem where "1986-04-28 00:00 EDT" was
rejected when TZ="America/Indianapolis" because the nearest DST
timestamp occurred in 1970, a temporal distance too great for the
old heuristic. This also also narrows the search a bit, which
is a minor performance win.

commit 6e8044e910600f71f4802dba2d105007af8428c3

Fix memmove call in vfprintf-internal.c:group_number
A recent GCC mainline change introduces errors of the form:
vfprintf-internal.c: In function 'group_number':
vfprintf-internal.c:2093:15: error: 'memmove' specified bound between 9223372036854775808 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=]
2093 | memmove (w, s, (front_ptr -s) * sizeof (CHAR_T));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is a genuine bug in the glibc code: s > front_ptr is always true
at this point in the code, and the intent is clearly for the
subtraction to be the other way round. The other arguments to the
memmove call here also appear to be wrong; w and s point just *after*
the destination and source for copying the rest of the number, so the
size needs to be subtracted to get appropriate pointers for the
copying. Adjust the memmove call to conform to the apparent intent of
the code, so fixing the -Wstringop-overflow error.
Now, if the original code were ever executed, a buffer overrun would
result. However, I believe this code (introduced in commit
edc1686af0c0fc2eb535f1d38cdf63c1a5a03675, "vfprintf: Reuse work_buffer
in group_number", so in glibc 2.26) is unreachable in prior glibc
releases (so there is no need for a bug in Bugzilla, no need to
consider any backports unless someone wants to build older glibc
releases with GCC 12 and no possibility of this buffer overrun
resulting in a security issue).
work_buffer is 1000 bytes / 250 wide characters. This case is only
reachable if an initial part of the number, plus a grouped copy of the
rest of the number, fail to fit in that space; that is, if the grouped
number fails to fit in the space. In the wide character case,
grouping is always one wide character, so even with a locale (of which
there aren't any in glibc) grouping every digit, a number would need
to occupy at least 125 wide characters to overflow, and a 64-bit
integer occupies at most 23 characters in octal including a leading 0.
In the narrow character case, the multibyte encoding of the grouping
separator would need to be at least 42 bytes to overflow, again
supposing grouping every digit, but MB_LEN_MAX is 16. So even if we
admit the case of artificially constructed locales not shipped with
glibc, given that such a locale would need to use one of the character
sets supported by glibc, this code cannot be reached at present. (And
POSIX only actually specifies the ' flag for grouping for decimal
output, though glibc acts on it for other bases as well.)
With binary output (if you consider use of grouping there to be
valid), you'd need a 15-byte multibyte character for overflow; I don't
know if any supported character set has such a character (if, again,
we admit constructed locales using grouping every digit and a grouping
separator chosen to have a multibyte encoding as long as possible, as
well as accepting use of grouping with binary), but given that we have
this code at all (clearly it's not *correct*, or in accordance with
the principle of avoiding arbitrary limits, to skip grouping on
running out of internal space like that), I don't think it should need
any further changes for binary printf support to go in.
On the other hand, support for large sizes of _BitInt in printf (see
the N2858 proposal) *would* require something to be done about such
arbitrary limits (presumably using dynamic allocation in printf again,
for sufficiently large _BitInt arguments only - currently only
floating-point uses dynamic allocation, and, as previously discussed,
that could actually be replaced by bounded allocation given smarter
code).
Tested with build-many-glibcs.py for aarch64-linux-gnu (GCC mainline).
Also tested natively for x86_64.

regex: copy back from Gnulib
Copy regex-related files back from Gnulib, to fix a problem with
static checking of regex calls noted by Martin Sebor. This merges the
following changes:
* New macro __attribute_nonnull__ in misc/sys/cdefs.h, for use later
when copying other files back from Gnulib.
* Use __GNULIB_CDEFS instead of __GLIBC__ when deciding
whether to include bits/wordsize.h etc.
* Avoid duplicate entries in epsilon closure table.
* New regex.h macro _REGEX_NELTS to let regexec say that its pmatch
arg should contain nmatch elts. Use that for regexec, instead of
__attr_access (which is incorrect).
* New regex.h macro _Attr_access_ which is like __attr_access except
portable to non-glibc platforms.
* Add some DEBUG_ASSERTs to pacify gcc -fanalyzer and to catch
recently-fixed performance bugs if they recur.
* Add Gnulib-specific stuff to port the dynarray- and lock-using parts
of regex code to non-glibc platforms.
* Fix glibc bug 11053.
* Avoid some undefined behavior when popping an empty fail stack.

io: Fix ftw internal realloc buffer (BZ #28126)
The 106ff08526d3ca did not take in consideration the buffer might be
reallocated if the total path is larger than PATH_MAX. The realloc
uses 'dirbuf', where 'dirstreams' is the allocated buffer.
Checked on x86_64-linux-gnu.

commit d57cdc1b5a52b5468b9259c0b9a215e22a1fa1f6
Author: Florian Weimer <fweimer@redhat.com>
Date: Tue Nov 8 14:15:02 2022 +0100
Linux: Support __IPC_64 in sysvctl *ctl command arguments (bug 29771)
Old applications pass __IPC_64 as part of the command argument because
old glibc did not check for unknown commands, and passed through the
arguments directly to the kernel, without adding __IPC_64.
Applications need to continue doing that for old glibc compatibility,
so this commit enables this approach in current glibc.
For msgctl and shmctl, if no translation is required, make
direct system calls, as we did before the time64 changes. If
translation is required, mask __IPC_64 from the command argument.
For semctl, the union-in-vararg argument handling means that
translation is needed on all architectures.
