glibc-2.19
The GNU C Library ================= The GNU C Library version 2.19 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 2.19 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 2.19 ===================== * The following bugs are resolved with this release: 156, 387, 431, 762, 832, 926, 2801, 4772, 6786, 6787, 6807, 6810, 6981, 7003, 9721, 9954, 10253, 10278, 11087, 11157, 11214, 12100, 12486, 12751, 12986, 13028, 13982, 13985, 14029, 14032, 14120, 14143, 14155, 14286, 14547, 14699, 14752, 14782, 14876, 14910, 15004, 15048, 15073, 15089, 15128, 15218, 15268, 15277, 15308, 15362, 15374, 15400, 15425, 15427, 15483, 15522, 15531, 15532, 15593, 15601, 15608, 15609, 15610, 15632, 15640, 15670, 15672, 15680, 15681, 15723, 15734, 15735, 15736, 15748, 15749, 15754, 15760, 15763, 15764, 15797, 15799, 15825, 15843, 15844, 15846, 15847, 15849, 15850, 15855, 15856, 15857, 15859, 15867, 15886, 15887, 15890, 15892, 15893, 15895, 15897, 15901, 15905, 15909, 15915, 15917, 15919, 15921, 15923, 15939, 15941, 15948, 15963, 15966, 15968, 15985, 15988, 15997, 16032, 16034, 16036, 16037, 16038, 16041, 16046, 16055, 16071, 16072, 16074, 16077, 16078, 16103, 16112, 16143, 16144, 16146, 16150, 16151, 16153, 16167, 16169, 16172, 16195, 16214, 16245, 16271, 16274, 16283, 16289, 16293, 16314, 16316, 16330, 16337, 16338, 16356, 16365, 16366, 16369, 16372, 16375, 16379, 16384, 16385, 16386, 16387, 16390, 16394, 16398, 16400, 16407, 16408, 16414, 16430, 16431, 16453, 16474, 16506, 16510, 16529 * Slovenian translations for glibc messages have been contributed by the Translation Project's Slovenian team of translators. * The public headers no longer use __unused nor __block. This change is to support compiling programs that are derived from BSD sources and use __unused internally, and to support compiling with Clang's -fblock extension which uses __block. * CVE-2012-4412 The strcoll implementation caches indices and rules for large collation sequences to optimize multiple passes. This cache computation may overflow for large collation sequences and may cause a stack or buffer overflow. This is now fixed to use a slower algorithm which does not use a cache if there is an integer overflow. * CVE-2012-4424 The strcoll implementation uses malloc to cache indices and rules for large collation sequences to optimize multiple passes and falls back to alloca if malloc fails, resulting in a possible stack overflow. The implementation now falls back to an uncached collation sequence lookup if malloc fails. * CVE-2013-4788 The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix (bug 15754). * CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes to the d_name member of struct dirent, or omit the terminating NUL character. (Bugzilla #14699). * CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and aligned_alloc functions could allocate too few bytes or corrupt the heap when passed very large allocation size values (Bugzilla #15855, #15856, #15857). * CVE-2013-4458 Stack overflow in getaddrinfo with large number of results for AF_INET6 has been fixed (Bugzilla #16072). * New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW, pap_CW, quz_PE, the_NP. * Substantially revised locales: gd_GB, ht_HT * The LC_ADDRESS field was updated to support country_car for almost all supported locales. * ISO 1427 definitions were updated. * ISO 3166 definitions were updated. * The localedef utility now supports --big-endian and --little-endian command-line options to generate locales for a different system from that for which the C library was built. * Binary locale files now only depend on the endianness of the system for which they are generated and not on other properties of that system. As a consequence, binary files generated with new localedef may be incompatible with old versions of the GNU C Library, and binary files generated with old localedef may be incompatible with this version of the GNU C Library, in the following circumstances: + Locale files may be incompatible on m68k systems. + Locale archive files (but not separate files for individual locales) may be incompatible on systems where plain "char" is signed. * The configure option --disable-versioning has been removed. Builds with --disable-versioning had not worked for several years. * ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh, cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue). * SystemTap probes for malloc have been introduced. * SystemTap probes for slow multiple precision fallback paths of transcendental functions have been introduced. * Support for powerpc64le has been added. * The soft-float powerpc port now supports e500 processors. * Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64. * A new feature test macro _DEFAULT_SOURCE is available to enable the same set of header declarations that are enabled by default, even when other feature test macros or compiler options such as -std=c99 would otherwise disable some of those declarations. * The _BSD_SOURCE feature test macro no longer enables BSD interfaces that conflict with POSIX. The libbsd-compat library (which was a dummy library that did nothing) has also been removed. * Preliminary documentation about Multi-Thread, Async-Signal and Async-Cancel Safety has been added.

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.

Optimized versions of memcpy, memset, and memcmp added for System z10 and zEnterprise z196. Implemented by Andreas Krebbel. * The new function secure_getenv allows secure access to the environment, returning NULL if running in a SUID/SGID process. This function replaces the internal function __secure_getenv. * SystemTap static probes have been added into the dynamic linker. Implemented by Gary Benson. * Optimizations of string functions strstr, strcasestr and memmem. Implemented by Maxim Kuvyrkov. * The minimum Linux kernel version that this version of the GNU C Library can be used with is 2.6.16. * Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for powerpc POWER7. Implemented by Will Schmidt. * New configure option --disable-nscd builds the C library such that it never attempts to contact the Name Service Caching Daemon (nscd). New configure option --disable-build-nscd avoids building nscd itself; this is the default if --disable-nscd is used. * Improved support for cross-compilation, including cross-testing and bootstrap builds without a previously built glibc. * Several testsuite tests are now able to test multiple IFUNC variants of an interface, rather than just testing the one that would be chooen by default. * New configure options --with-bugurl and --with-pkgversion, for distributors to use to embed their bug-reporting and package version information in --help and --version output. * The ttyname and ttyname_r functions on Linux now fall back to searching for the tty file descriptor in /dev/pts or /dev if /proc is not available. This allows creation of chroots without the procfs mounted on /proc. * The `crypt' function now fails if passed salt bytes that violate the specification for those values. On Linux, the `crypt' function will consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is enabled, and fail on encrypted strings using the MD5 or DES algorithm when the mode is enabled. * The `clock_*' suite of functions (declared in <time.h>) is now available directly in the main C library. Previously it was necessary to link with -lrt to use these functions. This change has the effect that a single-threaded program that uses a function such as `clock_gettime' (and is not linked with -lrt) will no longer implicitly load the pthreads library at runtime and so will not suffer the overheads associated with multi-thread support in other code such as the C++ runtime library. * New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ, sat_IN, and szl_PL.

The x32 target is selected by configuring glibc with: BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32' Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info. Implemented by H.J. Lu. * ISO C11 support: + define static_assert + do not declare gets + declare at_quick_exit and quick_exit also for ISO C11 + aligned_alloc. NB: The code is deliberately allows the size parameter to not be a multiple of the alignment.

Implemented by Ulrich Drepper. * More generic and 64-bit performance optimizations to math functions. Implemented by Ulrich Drepper. * New configure option --enable-obsolete-rpc makes the deprecated RPC headers and functions available at compile time as they were before version 2.14. This option will be removed at some time in the future after the TI-RPC library becomes fully sufficient for the needs of existing applications. * Compatibility code for Linux kernel versions before 2.4 has been removed. Note that glibc is not expected to work with any Linux kernel version before 2.6. * New header <sys/auxv.h> and function getauxval allowing easy access to the AT_* key-value pairs passed from the Linux kernel. The header also defines the HWCAP_* bits associated with the AT_HWCAP key. * New locales: mag_IN * New configure option --enable-systemtap builds SystemTap static probes into libc for setjmp and longjmp and into libpthread for various operations. So far the setjmp/longjmp probes and some of the libpthread probes are provided only for i*86 and x86_64. Implemented by Roland McGrath and Rayson Ho. * Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva. * More optimized functions for PowerPC. Implemented by Adhemerval Zanella and Will Schmidt. * More optimized functions for SPARC. Implemented by David S. Miller. * Improved support for cross-compilation, especially bootstrap builds without a previously built glibc. * Ports for the TILE-Gx and TILEPro families of processors. Contributed by Chris Metcalf from Tilera. * Support for the old ARM ABI has been removed from ports. Only the EABI is now supported for ARM processors. * The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3 as the name of the dynamic linker, to distinguish it from the /lib/ld-linux.so.3 dynamic linker used for the base EABI. * Support for CRIS has been removed from ports. * A new class of installed header has been documented for low-level platform-specific functionality. PowerPC added the first instance with a function to provide time base register access. Contributed by Tulio Magno Quites Machado Filho. * ix86 configurations now install header files that are consistent with what x86-64 configurations install. These same header files can be used for -m32, -m64, or -mx32 builds. Contributed by H.J. Lu. * Math library bug fixes. A thorough audit of all open math library bugs was conducted by Joseph Myers. Significant progress was made on many math library bugs resulting in more accurate exceptions and function results. Many thanks to all those that contributed including Andreas Jaeger for his patch review and work on the x87 trigonometric instruction issues. * Timezone data is no longer installed. Timezone-related binaries and scripts will continue to be installed. Users should obtain their timezone data from their distribution provider or from the tzdata package at <ftp://munnari.oz.au/pub/>.
