The GNU C Library provides the most important standard libraries used
by nearly all programs: the standard C library, the standard math

  - Add cross development packages for aarch64 and riscv64.
* Mon Aug 02 2021 Andreas Schwab <>
  - Update to glibc 2.34
    Major new features:
    * When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
      PTHREAD_STACK_MIN is no longer constant and is redefined to
    * The dynamic linker implements the --list-diagnostics option, printing
      a dump of information related to IFUNC resolver operation and
      glibc-hwcaps subdirectory selection
    * On Linux, the function execveat has been added
    * The ISO C2X function timespec_getres has been added
    * The feature test macro __STDC_WANT_IEC_60559_EXT__, from draft ISO
      C2X, is supported to enable declarations of functions defined in Annex F
      of C2X
    * Add support for 64-bit time_t on configurations like x86 where time_t
      is traditionally 32-bit
    * The main gconv-modules file in glibc now contains only a small set of
      essential converter modules and the rest have been moved into a supplementary
      configuration file gconv-modules-extra.conf in the gconv-modules.d directory
      in the same GCONV_PATH
    * On Linux, a new tunable, glibc.pthread.stack_cache_size, can be used
      to configure the size of the thread stack cache
    * The function _Fork has been added as an async-signal-safe fork replacement
      since Austin Group issue 62 droped the async-signal-safe requirement for
      fork (and it will be included in the future POSIX standard)
    * On Linux, the close_range function has been added
    * The function closefrom has been added
    * The posix_spawn_file_actions_closefrom_np function has been added, enabling
      posix_spawn and posix_spawnp to close all file descriptors great than or
      equal to a giver integer
    Deprecated and removed features, and other changes affecting compatibility:
    * The function pthread_mutex_consistent_np has been deprecated
    * The function pthread_mutexattr_getrobust_np has been deprecated
    * The function pthread_mutexattr_setrobust_np has been deprecated
    * The function pthread_yield has been deprecated
    * The function inet_neta declared in <arpa/inet.h> has been deprecated
    * Various rarely-used functions declared in <resolv.h> and
      <arpa/nameser.h> have been deprecated
    * The pthread cancellation handler is now installed with SA_RESTART and
      pthread_cancel will always send the internal SIGCANCEL on a cancellation
    * The symbols mallwatch and tr_break are now deprecated and no longer used in
    * The __morecore and __after_morecore_hook malloc hooks and the default
      implementation __default_morecore have been removed from the API
    * Debugging features in malloc such as the MALLOC_CHECK_ environment variable
      (or the glibc.malloc.check tunable), mtrace() and mcheck() have now been
      disabled by default in the main C library
    * The deprecated functions malloc_get_state and malloc_set_state have been
      moved from the core C library into
    * The deprecated memory allocation hooks __malloc_hook, __realloc_hook,
      __memalign_hook and __free_hook are now removed from the API
    Changes to build and runtime requirements:
    * On Linux, the shm_open, sem_open, and related functions now expect the
      file shared memory file system to be mounted at /dev/shm
    Security related changes:
      CVE-2021-27645: The nameserver caching daemon (nscd), when processing

    * The dynamic linker accepts the --argv0 argument and provides opportunity
      to change argv[0] string.
    * The dynamic linker loads optimized implementations of shared objects
      from subdirectories under the glibc-hwcaps directory on the library
      search path if the system's capabilities meet the requirements for
      that subdirectory.
    * The new --help option of the dynamic linker provides usage and
      information and library search path diagnostics.

      hardcoded to double.
    * A future version of glibc will stop loading shared objects from the
      "tls" subdirectories on the library search path, the subdirectory that
      corresponds to the AT_PLATFORM system name, and also stop employing
      the legacy AT_HWCAP search mechanism.
    * CVE-2021-3326: An assertion failure during conversion from the
      ISO-20220-JP-3 character set using the iconv function has been fixed.
