* Mon Aug 02 2021 Andreas Schwab - Update to glibc 2.34 Major new features:

* On Linux, a new tunable, glibc.pthread.stack_cache_size, can be used to configure the size of the thread stack cache

* 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 __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 libc_malloc_debug.so
* 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 a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system CVE-2021-33574: The mq_notify function has a potential use-after-free issue when using a notification type of SIGEV_THREAD and a thread attribute with a non-default affinity mask CVE-2021-35942: The wordexp function may overflow the positional parameter number when processing the expansion resulting in a crash- nss-database-check-reload.patch, nss-load-chroot.patch, x86-isa-level.patch, nscd-netgroupcache.patch, nss-database-lookup.patch, select-modify-timeout.patch, nptl-db-libpthread-load-order.patch, rawmemchr-warning.patch, tst-cpu-features-amx.patch, mq-notify-use-after-free.patch: Removed- bsc#1181403- bsc#1184035- bsc#1187911- jsc#PED-987

* The new --help option of the dynamic linker provides usage and information and library search path diagnostics.
* The mallinfo2 function is added to report statistics as per mallinfo, but with larger field widths to accurately report values that are larger than fit in an integer.
* Add to provide query macros for x86 CPU features.
* A new fortification level _FORTIFY_SOURCE=3 is available.
* The mallinfo function is marked deprecated.
* When dlopen is used in statically linked programs, alternative library implementations from HWCAP subdirectories are no longer loaded.

* On s390(x), the type float_t is now derived from the macro __FLT_EVAL_METHOD__ that is defined by the compiler, instead of being 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.
