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.

* 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

* 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.
