- Update to glibc-2.25.90.20170720.gc771b59a24c0
* A per-thread cache has been added to malloc
* Unicode 10.0.0 Support
* Improvements to the DNS stub resolver
* New function reallocarray, which resizes an allocated block (like
realloc) to the product of two sizes, with a guaranteed clean failure
upon integer overflow in the multiplication
* New wrappers for the Linux-specific system calls preadv2 and pwritev2
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location
* The DNS stub resolver no longer performs EDNS fallback
* res_mkquery and res_nmkquery no longer support the IQUERY opcode
* The _res_opcodes variable has been removed from libresolv
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler
* The nonstandard header <xlocale.h> has been removed
* The obsolete header <sys/ultrasound.h> has been removed
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>
* The obsolete function cfree has been removed
* The stack_t type no longer has the name struct sigaltstack
* The ucontext_t type no longer has the name struct ucontext
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been

- Update to glibc 2.21 release.
* A new semaphore algorithm has been implemented in generic C code for all
machines
* Added support for TSX lock elision of pthread mutexes on powerpc32,
powerpc64 and powerpc64le
* Optimized strcpy, stpcpy, strchrnul and strrchr implementations for
AArch64
* i386 memcpy functions optimized with SSE2 unaligned load/store
* New locales: tu_IN, bh_IN, raj_IN, ce_RU
* The obsolete sigvec function has been removed
- Patches from upstream removed
* ifunc-x86-slow-sse4.patch
* pthread-mutex-trylock-elision.patch
- o-tmpfile.patch: Fix value of O_TMPFILE for architectures with
non-default O_DIRECTORY (BZ #17912)

- Update to glibc 2.17.90 85891acadf1b:
* CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
has been fixed by disabling the use of pt_chown (Bugzilla #15755).
Distributions can re-enable building and using pt_chown via the new configure
option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
considerable security risks and should only be used if the distribution
understands and accepts the risks.
* CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
#15078).
* CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
fixed (Bugzilla #15330).
* Add support for calling C++11 thread_local object destructors on thread
and program exit. This needs compiler support for offloading C++11
destructor calls to glibc.
* Improved worst case performance of libm functions with double inputs and
output.
* Support for priority inherited mutexes in pthread condition variables on
non-x86 architectures.
* Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
* Optimized string functions for ARM. Implemented by Will Newton and
Richard Henderson.
* Added a benchmark framework to track performance of functions in glibc.
* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
It is based on draft TS 18661 and currently enabled as a GNU extension.
* On Linux, the clock function now uses the clock_gettime system call
for improved precision, rather than old times system call.
* Added new API functions pthread_getattr_default_np and
pthread_setattr_default_np to get and set the default pthread
attributes of a process.
* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
