Subject: musl 1.2.6 released
This release includes the fix for CVE-2025-26519 affecting iconv that
was previously only available as patches, lifts the artificial group
count limit in initgroups, adds the new POSIX-2024 posix_getdents
interface and Linux-specific renameat2 interface, extends TLSDESC and
vdso clock_gettime support to more archs, and fixes longstanding known
wrong behavior of pwrite with O_APPEND-mode files, making use of the
new RWF_NOAPPEND flag added in Linux 6.9, with fallback to report an
error rather than silently giving wrong behavior on older kernels.
Fixes for a number of other bugs, new/future conformance requirements,
and compatibility issues are also included. Most of these are minor or
specific to niche archs or unusual usage of libc interfaces. Some of
the more notable ones include possible loss or delay of wake events
under a race condition in sem_post, failure by printf to honor hex
float precision correctly in some cases, and wrong choice of canonical
"zero compression" in converting IPv6 addresses to strings.
