glibc/ldconfig-concurrency.patch
Andreas Schwab a589b37fb7 Accepting request 909816 from home:Andreas_Schwab:Factory
- 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
    sysconf(_SC_THREAD_STACK_MIN)
  * Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ
  * 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
