search mechanism, which was deprecated in version 2.33

- Update to glibc 2.35
Major new features:
* Unicode 14.0.0 Support
* Bump r_version in the debugger interface to 2
* Support for the C.UTF-8 locale has been added to glibc
* <math.h> functions that round their results to a narrower type, and
corresponding <tgmath.h> macros, are added from TS 18661-1:2014, TS
18661-3:2015 and draft ISO C2X
* <math.h> functions for floating-point maximum and minimum,
corresponding to new operations in IEEE 754-2019, and corresponding
<tgmath.h> macros, are added from draft ISO C2X
* <math.h> macros for single-precision float constants are added as a
GNU extension
* The __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__ macros are
predefined as specified in TS 18661-1:2014
* The exp10 functions in <math.h> now have a corresponding type-generic
macro in <tgmath.h>
* The ISO C2X macro _PRINTF_NAN_LEN_MAX has been added to <stdio.h>
* printf-family functions now support the %b format for output of
integers in binary, as specified in draft ISO C2X, and the %B variant
of that format recommended by draft ISO C2X
* A new DSO sorting algorithm has been added in the dynamic linker that uses
topological sorting by depth-first search (DFS), solving performance issues
of the existing sorting algorithm when encountering particular circular
object dependency cases
* A new tunable, glibc.rtld.dynamic_sort, can be used to select between
the two DSO sorting algorithms
* ABI support for a new function '__memcmpeq'. '__memcmpeq' is meant
to be used by compilers for optimizing usage of 'memcmp' when its
return value is only used for its boolean status

- 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.

* The DNS stub resolver will optionally send the AD (authenticated data) bit
in queries if the trust-ad option is set via the options directive in
/etc/resolv.conf (or if RES_TRUSTAD is set in _res.options)
* The totalorder and totalordermag functions, and the corresponding
functions for other floating-point types, now take pointer arguments to
avoid signaling NaNs possibly being converted to quiet NaNs in argument
passing
* The obsolete function stime is no longer available to newly linked
binaries, and its declaration has been removed from <time.h>
* The gettimeofday function no longer reports information about a
system-wide time zone
* If a lazy binding failure happens during dlopen, during the execution of
an ELF constructor, the process is now terminated

used CPU and NUMA node

(PPC_FEATURE2_HTM_NOSC on hwcap2)
* The functions posix_spawn_file_actions_addchdir_np and
posix_spawn_file_actions_addfchdir_np have been added, enabling
posix_spawn and posix_spawnp to run the new process in a different
directory
* The popen and system do not run atfork handlers anymore (BZ#17490)
* strftime's default formatting of a locale's alternative year (%Ey)
has been changed to zero-pad the year to a minimum of two digits,
like "%y"
* As a GNU extension, the '_' and '-' flags can now be applied to
"%EY" to control how the year number is formatted
* The glibc.tune tunable namespace has been renamed to glibc.cpu and the
tunable glibc.tune.cpu has been renamed to glibc.cpu.name
* The type of the pr_uid and pr_gid members of struct elf_prpsinfo, defined
in <sys/procfs.h>, has been corrected to match the type actually used by
the Linux kernel
* An archaic GNU extension to scanf, under which '%as', '%aS', and '%a[...]'
meant to scan a string and allocate space for it with malloc, is now
restricted to programs compiled in C89 or C++98 mode with _GNU_SOURCE
defined

* The abort function terminates the process immediately, without flushing
stdio streams
* On platforms where long double has the IEEE binary128 format (aarch64,
alpha, mips64, riscv, s390 and sparc), the math library now implements
_Float128 interfaces for that type, as defined by ISO/IEC TS 18661-3:2015
These are the same interfaces added in version 2.26 for some platforms where
this format is supported but is not the format of long double
* On platforms with support for _Float64x (aarch64, alpha, i386, ia64,

netlink socket
* A defect in the malloc implementation, present since glibc 2.15 (2012)
or glibc 2.10 via --enable-experimental-malloc (2009), could result in
the unnecessary serialization of memory allocation requests across
threads

query_module and uselib are no longer available to newly linked
binaries

- Update to glibc 2.17.90 85891acadf1b:
* CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
has been fixed by disabling the use of pt_chown (Bugzilla #15755).
Distributions can re-enable building and using pt_chown via the new configure
option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
considerable security risks and should only be used if the distribution
understands and accepts the risks.
* CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
#15078).
* CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
fixed (Bugzilla #15330).
* Add support for calling C++11 thread_local object destructors on thread
and program exit. This needs compiler support for offloading C++11
destructor calls to glibc.
* Improved worst case performance of libm functions with double inputs and
output.
* Support for priority inherited mutexes in pthread condition variables on
non-x86 architectures.
* Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
* Optimized string functions for ARM. Implemented by Will Newton and
Richard Henderson.
* Added a benchmark framework to track performance of functions in glibc.
* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
It is based on draft TS 18661 and currently enabled as a GNU extension.
* On Linux, the clock function now uses the clock_gettime system call
for improved precision, rather than old times system call.
* Added new API functions pthread_getattr_default_np and
pthread_setattr_default_np to get and set the default pthread
attributes of a process.
* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
