+
+- Update to glibc 2.32
+ * Unicode 13.0.0 Support
+ * New locale added: ckb_IQ
+ * The GNU C Library now loads audit modules listed in the DT_AUDIT and
+ DT_DEPAUDIT dynamic section entries of the main executable
+ * powerpc64le supports IEEE128 long double libm/libc redirects when
+ using the -mabi=ieeelongdouble to compile C code on supported GCC
+ toolchains
+ * To help detect buffer overflows and other out-of-bounds accesses
+ several APIs have been annotated with GCC 'access' attribute
+ * On Linux, functions the pthread_attr_setsigmask_np and
+ pthread_attr_getsigmask_np have been added
+ * The GNU C Library now provides the header file <sys/single_threaded.h>
+ which declares the variable __libc_single_threaded
+ * The functions sigabbrev_np and sigdescr_np have been added
+ * The functions strerrorname_np and strerrordesc_np have been added
+ * AArch64 now supports standard branch protection security hardening
+ in glibc when it is built with a GCC that is configured with
+ --enable-standard-branch-protection (or if -mbranch-protection=standard
+ flag is passed when building both GCC target libraries and glibc,
+ in either case a custom GCC is needed)
+ * The deprecated <sys/sysctl.h> header and the sysctl function have been
+ removed
+ * The sstk function is no longer available to newly linked binaries
+ * The legacy signal handling functions siginterrupt, sigpause, sighold,
+ sigrelse, sigignore and sigset, and the sigmask macro have been
+ deprecated
+ * ldconfig now defaults to the new format for ld.so.cache
+ * The deprecated arrays sys_siglist, _sys_siglist, and sys_sigabbrev
+ are no longer available to newly linked binaries, and their declarations
+ have been removed from <string.h>
+ * The deprecated symbols sys_errlist, _sys_errlist, sys_nerr, and _sys_nerr
+ are no longer available to newly linked binaries, and their declarations
+ have been removed from from <stdio.h>
+ * Both strerror and strerror_l now share the same internal buffer in the
+ calling thread, meaning that the returned string pointer may be invalided
+ or contents might be overwritten on subsequent calls in the same thread or
+ if the thread is terminated
+ * Using weak references to libpthread functions such as pthread_create
+ or pthread_key_create to detect the singled-threaded nature of a
+ program is an obsolescent feature
+ * The "files" NSS module no longer supports the "key" database (used for
+ secure RPC)
+ * The __morecore and __after_morecore_hook malloc hooks and the default
+ implementation __default_morecore have been deprecated
+ * The hesiod NSS module has been deprecated and will be removed in a
+ future version of glibc
+ * CVE-2016-10228: An infinite loop has been fixed in the iconv program when
+ invoked with the -c option and when processing invalid multi-byte input
+ sequences
+ * CVE-2020-10029: Trigonometric functions on x86 targets suffered from stack
+ corruption when they were passed a pseudo-zero argument
+ * CVE-2020-1752: A use-after-free vulnerability in the glob function when
+ expanding ~user has been fixed.
+ * CVE-2020-6096: A signed comparison vulnerability in the ARMv7 memcpy and
+ memmove functions has been fixed

Subject: [PATCH] x86-64: Fix FMA4 detection in ifunc [BZ #26534]
A typo in commit 107e6a3c2212ba7a3a4ec7cae8d82d73f7c95d0b causes the
FMA4 code path to be taken on systems that support FMA, even if they do
not support FMA4. Fix this to detect FMA4.

Subject: [PATCH] Correct locking and cancellation cleanup in syslog functions
(bug 26100)
Properly serialize the access to the global state shared between the
syslog functions, to avoid races in multithreaded processes. Protect a
local allocation in the __vsyslog_internal function from leaking during
cancellation.
