Subject: The GNU C Library version 2.18 is now available

The GNU C Library ================= The GNU C Library version 2.18 is now available. The GNU C Library is used as *the* C library in the GNU systems and most systems with the Linux 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 2.18 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 NEWS for version 2.18 ==================== * The following bugs are resolved with this release: 2546, 2560, 5159, 6809, 7006, 10060, 10062, 10283, 10357, 10686, 11120, 11561, 12310, 12387, 12492, 12515, 12723, 13550, 13889, 13951, 13988, 14142, 14176, 14200, 14256, 14280, 14293, 14317, 14327, 14478, 14496, 14582, 14686, 14812, 14888, 14894, 14907, 14908, 14909, 14920, 14952, 14964, 14981, 14982, 14985, 14991, 14994, 14996, 15000, 15003, 15006, 15007, 15014, 15020, 15022, 15023, 15036, 15054, 15055, 15062, 15078, 15084, 15085, 15086, 15100, 15160, 15214, 15221, 15232, 15234, 15283, 15285, 15287, 15304, 15305, 15307, 15309, 15327, 15330, 15335, 15336, 15337, 15339, 15342, 15346, 15359, 15361, 15366, 15380, 15381, 15394, 15395, 15405, 15406, 15409, 15416, 15418, 15419, 15423, 15424, 15426, 15429, 15431, 15432, 15441, 15442, 15448, 15465, 15480, 15485, 15488, 15490, 15492, 15493, 15497, 15506, 15529, 15536, 15553, 15577, 15583, 15618, 15627, 15631, 15654, 15655, 15666, 15667, 15674, 15711, 15755, 15759. * 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. * Port to Xilinx MicroBlaze contributed by David Holsgrove. * Optimized string functions for AArch64. Implemented by Marcus Shawcroft. * Optimized string functions for ARM. Implemented by Will Newton and Richard Henderson. * Optimized libm functions for SPARC. Implemented by David S. Miller. * Support for building more of ARM glibc as Thumb-2 code. Implemented by Richard Henderson. * Support for building most of MIPS glibc as MIPS16 code. Implemented by Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov. * 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. This may improve lock scaling of existing programs on TSX capable systems. When the --enable-lock-elision=yes parameter is specified at configure time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT mutexes. * Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10 availability). Implemented by Ryan S. Arnold. * Support added for POWER8 platform. Implemented by Ryan S. Arnold. Contributors ============ This release was made possible by the contributions of many people.
