- iconv GBK now properly includes euro symbol
- strptime now accepts conversion specifiers added in POSIX-2024
- inet_ntop IPv6 "zero compression" now conforms to RFC 5952
bugs fixed:
- iconv euc-kr decoder could do oob writes on invalid inputs (CVE-2025-26519)
- iconv shift_jis decoder could produce wrong outputs for some invalid inputs
- printf did not honor hex float precision correctly in some cases
- lost or delayed wakes in sem_post under race condition
- termios input speed handling was wrong
- strcasestr failed to match zero-length needle
- fma handled corner case with negative zero wrongly
- syslog LOG_MAKEPRI macro was incorrect
- timer_create is no longer affected by known pthread_barrier bugs
- sysconf(_SC_MINSIGSTKSZ) computed min size incorrectly
- statx emulation left some fields uninitialized
- mntent wrongly included final newline in parsed field output
- SIGEV_THREAD timers could abort process if SIGTIMER became unblocked
- bind_textdomain_codeset returned wrong value
arch-specific bugs fixed:
- early dynamic linker handled page size wrong on dynamic pagesize archs
- arm and aarch64 crti/n files had wrong alignment
- m68k POLLWRNORM and POLLWRBAND values were incorrect
- x32 mq ABI was mismatched

Changes:
new features:
- qsort_r function (POSIX-future)
- pthread_getname_np extension function
- hard float on SPE FPU for powerpc-sf
- SEEK_DATA and SEEK_HOLE exposed in unistd.h (Linux extensions)
compatibility:
- free now preserves errno (POSIX-future requirement)
- setjmp is declared explicitly with returns_twice for non-GCC compilers
- macro version of isascii is no longer defined for C++
- dynamic linker now tolerates zero-length LOAD segments
- epoll_[p]wait is now a cancellation point
- pwd/grp functions no longer fail on systems without AF_UNIX support
- POSIX TZ parsing is stricter to allow more names to fallback to files
- NULL is now defined as nullptr when used in C++11 or later
- gettext now accepts null pointer as argument
bugs fixed:
- old regression in wcwidth of Hangul combining (vowel/final) letters
- duplocale used wrong malloc when malloc was replaced (1.2.2 regression)
- fmaf rounded wrong on archs without FE_TOWARDZERO (all softfloat archs)
- popen didn't honor requirement not to leak other popen pipe fds to child
- aligned_alloc and variants crashed on allocation failure
- dl_iterate_phdr reported incorrect module TLS pointers
- mishandling of some inputs in acoshf and expm1f and functions using them
- potentially wrong-sign zero in cproj functions at infinity
- multiple bugs in legacy function cuserid
- minor posix_spawn file actions API conformance issues
- pthread_setname_np fd leak
- out-of-bound read in zoneinfo handling with distant-past times
- out-of-tree builds lacked generated debug cfi for x86 asm
arch-specific bugs fixed:
- powerpc (32-bit) struct shmid_ds layout was wrong for some fields
- time64 struct layout was wrong in sound ioctl fallback (32-bit archs)
In addition it contains the following improvements:
* protect stack canary from leak via read-as-string by zeroing second byte
* fix excessively slow TLS performance on some mips models

"This release makes improvements with respect to default thread stack
size, including increasing the default from 80k to 128k, increasing
the default guard size from 4k to 8k, and allowing the default to be
increased via ELF headers so that programs that need larger stacks can
be build without source-level changes, using just LDFLAGS.
Insufficient stack size for AIO threads on kernels that don't honor
the constant MINSIGSTKSZ is also fixed.
The glob core has been rewritten to fix inability to see past
searchable-but-unreadable path components, and to avoid excessive
stack usage and unnecessary syscalls. The tsearch AVL tree
implementation has also been rewritten for better size and
performance. The math library adds more native single-instruction
implementations for arm, s390x, powerpc, and x86_64.
Various bugs are fixed, including several possible deadlocks, one of
which was a new regression in 1.1.20."

This updates musl from a commit between 1.1.18 and 1.1.19 to the final
release of the version 1.1.19.
This mostly fixes bugs in musl.
The size of the uncompressed binary is increased by about 4 KB.

Currently the OpenWRT boot scripts write the timezone configuration to
/tmp/TZ, relying on the behaviour of uClibc that the timezone is read
from /etc/TZ if no TZ env variable is found.
This works because /etc/TZ is a symlink to /tmp/TZ.
Musl libc however only reads the timezone from the TZ env variable and
if it doesn't find it or it's empty, it will look for a zoneinfo
file, that doesn't exist.
So in musl builds no timezone is ever set.
This patch fixes the issue by having musl libc behave like uClibc: if no
TZ env variable is found it will try to load it from /etc/TZ.
