- 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

- Update to glibc 2.33
* The dynamic linker accepts the --list-tunables argument which prints
all the supported tunables.
* 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.
* 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 <sys/platform/x86.h> 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.
* The deprecated <sys/vtimes.h> header and the function vtimes have been
removed.
* 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.
* CVE-2021-3326: An assertion failure during conversion from the
ISO-20220-JP-3 character set using the iconv function has been fixed.
