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,

  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.

* Support for the x32 ABI on x86-64 added.  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.  This is a moronic requirement
    in the standard but it is only a requirement on the caller, not the
    implementation.

+ timespec_get added

+ uchar.h support added

+ CMPLX, CMPLXF, CMPLXL added

Implemented by Ulrich Drepper.

* Support for the IA-64 has been moved to ports.

* Remove support for anything but ELF binary format

* Checking versions of poll, ppoll added.
  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/>.
