The GNU C Library
================= The GNU C Library version 2.17 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 2.17 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 2.17 ==================== * The following bugs are resolved with this release: 1349, 3439, 3479, 3665, 5044, 5246, 5298, 5400, 6530, 6677, 6778, 6808, 9685, 9914, 10014, 10038, 10114, 10631, 10873, 11438, 11607, 11638, 11741, 12140, 13013, 13412, 13542, 13601, 13603, 13604, 13629, 13679, 13696, 13698, 13717, 13741, 13759, 13761, 13763, 13881, 13939, 13950, 13952, 13966, 14042, 14047, 14090, 14150, 14151, 14152, 14154, 14157, 14166, 14173, 14195, 14197, 14237, 14246, 14251, 14252, 14283, 14298, 14303, 14307, 14328, 14331, 14336, 14337, 14347, 14349, 14368, 14376, 14417, 14447, 14459, 14476, 14477, 14501, 14505, 14510, 14516, 14518, 14519, 14530, 14532, 14538, 14543, 14544, 14545, 14557, 14562, 14568, 14576, 14579, 14583, 14587, 14595, 14602, 14610, 14621, 14638, 14645, 14648, 14652, 14660, 14661, 14669, 14672, 14683, 14694, 14716, 14719, 14743, 14767, 14783, 14784, 14785, 14793, 14796, 14797, 14801, 14803, 14805, 14807, 14811, 14815, 14821, 14822, 14824, 14828, 14831, 14833, 14835, 14838, 14856, 14863, 14865, 14866, 14868, 14869, 14871, 14872, 14879, 14889, 14893, 14898, 14914. * Optimization of memcpy for MIPS. * CVE-2011-4609 svc_run() produces high cpu usage when accept fails with EMFILE has been fixed (Bugzilla #14889). * The add-on ports collection is now distributed in the "ports" subdirectory of the main GNU C Library distribution, rather than separately. * Port to ARM AArch64 contributed by Linaro. * Support for STT_GNU_IFUNC symbols added for s390 and s390x. 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.
