The GNU C Library
=================

The GNU C Library version 2.22 is now available.

The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.

The GNU C Library is primarily designed to be a portable
and high performance C library.  It follows all relevant
standards including ISO C11 and POSIX.1-2008.  It is also
internationalized and has one of the most complete
internationalization interfaces known.

The GNU C Library webpage is at http://www.gnu.org/software/libc/

Packages for the 2.22 release may be downloaded from:
        http://ftpmirror.gnu.org/libc/
        http://ftp.gnu.org/gnu/libc/

The mirror list is at http://www.gnu.org/order/ftp.html

* Cache information can be queried via sysconf() function on s390 e.g. with
  _SC_LEVEL1_ICACHE_SIZE as argument.

* A buffer overflow in gethostbyname_r and related functions performing DNS
  requests has been fixed.  If the NSS functions were called with a
  misaligned buffer, the buffer length change due to pointer alignment was
  not taken into account.  This could result in application crashes or,
  potentially arbitrary code execution, using crafted, but syntactically
  valid DNS responses.  (CVE-2015-1781)

* The time zone file parser has been made more robust against crafted time
  zone files, avoiding heap buffer overflows related to the processing of
  the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
  large time zone data files.  Overly long time zone specifiers in the TZ
  variable no longer result in stack overflows and crashes.

* A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
  for LD and GD on x86 and x86-64, has been implemented.  You will need
  binutils-2.24 or later to enable this optimization.

* Character encoding and ctype tables were updated to Unicode 7.0.0, using
  new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red
  Hat).  These updates cause user visible changes, such as the fix for bug
  17998.

* CVE-2014-8121 The NSS backends shared internal state between the getXXent
  and getXXbyYY NSS calls for the same database, causing a denial-of-service
  condition in some applications.

* Added vector math library named libmvec with the following vectorized x86_64
  implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf,
  pow, powf.
  The library can be disabled with --disable-mathvec. Use of the functions is
  enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0.
  Shared library libmvec.so is linked in as needed when using -lm (no need to
  specify -lmvec explicitly for not static builds).
  Visit <https://sourceware.org/glibc/wiki/libmvec> for detailed information.

* A new fmemopen implementation has been added with the goal of POSIX
  compliance. The new implementation fixes the following long-standing
  issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
  old implementation is still present for use be by existing binaries.

* The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
  releases.  It has been fixed to match 2.19 and older, but binaries built
  against 2.20 and 2.21 might need to be recompiled.  See BZ#18694.

* Port to Native Client running on ARMv7-A (--host=arm-nacl).
