Summary: Standard Shared Libraries (from the GNU C Library) |
The GNU C Library provides the most important standard libraries used by nearly all programs: the standard C library, the standard math library, and the POSIX thread library. A system is not functional without these libraries.
GPL-2.0-or-later AND LGPL-2.1-or-later AND LGPL-2.1-or-later WITH GCC-exception-2.0
* Mon Jul 29 2024 Andreas Schwab <schwab@suse.de> - Update to glibc 2.40 * The <stdbit.h> header type-generic macros have been changed when using GCC 14.1 or later to use __builtin_stdc_bit_ceil etc. built-in functions * The GNU C Library now supports a feature test macro _ISOC23_SOURCE to enable features from the ISO C23 standard * The ISO C23 function families introduced in TS 18661-4:2015 are now supported in <math.h> * A new tunable, glibc.rtld.enable_secure, can be used to run a program as if it were a setuid process * On Linux, the epoll header was updated to include epoll ioctl definitions and the related structure added in Linux kernel 6.9 * The fortify functionality has been significantly enhanced for building programs with clang against the GNU C Library * Many functions have been added to the vector library for aarch64 * On x86, memset can now use non-temporal stores to improve the performance of large writes * Architectures which use a 32-bit seconds-since-epoch field in struct lastlog, struct utmp, struct utmpx (such as i386, powerpc64le, rv32, rv64, x86-64) switched from a signed to an unsigned type for that field * __rseq_size now denotes the size of the active rseq area (20 bytes initially), not the size of struct rseq (32 bytes initially). - arm-dl-start-user.patch, duplocale-global-locale.patch, elf-parse-tunables.patch, glibc-CVE-2024-33599-nscd-Stack-based-buffer-overflow-in-n.patch, glibc-CVE-2024-33600-nscd-Avoid-null-pointer-crashes-after.patch, glibc-CVE-2024-33600-nscd-Do-not-send-missing-not-found-re.patch, glibc-CVE-2024-33601-CVE-2024-33602-nscd-netgroup-Use-two.patch, iconv-iso-2022-cn-ext.patch, nscd-netgroup-cache-timeout.patch, s390-clone-error-clobber-r7.patch, sigisemptyset.patch, stdbit-builtins.patch, utmp-time-bits.patch: Removed - glibc-2.3.90-langpackdir.diff: Rediff * Mon Jun 03 2024 Dominique Leuenberger <dimstar@opensuse.org> - Also provide glibc-locale-base-<targettype> from glibc-gconv-modules-extra-<targettype>: the package was merged in the baselibs.conf case, so the capability is there.

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 * Support for automatically registering threads with the Linux rseq system call has been added * A symbolic link to the dynamic linker is now installed under /usr/bin/ld.so (or more precisely, '${bindir}/ld.so') * All programs and the testsuite in glibc are now built as position independent executables (PIE) by default on toolchains and architectures that support it * On Linux, a new tunable, glibc.malloc.hugetlb, can be used to either make malloc issue madvise plus MADV_HUGEPAGE on mmap and sbrk or to use huge pages directly with mmap calls with the MAP_HUGETLB flags) * The printf family of functions now handles the flagged %#m conversion specifier, printing errno as an error constant (similar to strerrorname_np) * The function _dl_find_object has been added * On Linux, the epoll_pwait2 function has been added * The function posix_spawn_file_actions_addtcsetpgrp_np has been added, enabling posix_spawn and posix_spawnp to set the controlling terminal in the new process in a race free manner * Source fortification (_FORTIFY_SOURCE) level 3 is now available for applications compiling with glibc and gcc 12 and later Deprecated and removed features, and other changes affecting compatibility: * On x86-64, the LD_PREFER_MAP_32BIT_EXEC environment variable support has been removed since the first PT_LOAD segment is no longer executable due to defaulting to -z separate-code * The r_version update in the debugger interface makes the glibc binary incompatible with GDB * Intel MPX support (lazy PLT, ld.so profile, and LD_AUDIT) has been removed * The catchsegv script and associated libSegFault.so shared object have been removed * Support for prelink will be removed in the next release; this includes removal of the LD_TRACE_PRELINKING, and LD_USE_LOAD_BIAS, environment variables and their functionality in the dynamic loader Changes to build and runtime requirements: * The audit module interface version LAV_CURRENT is increased to enable proper bind-now support * The audit interface on aarch64 is extended to support both the indirect result location register (x8) and NEON Q register Security related changes: * CVE-2022-23219: Passing an overlong file name to the clnt_create legacy function could result in a stack-based buffer overflow when using the "unix" protocol * CVE-2022-23218: Passing an overlong file name to the svcunix_create legacy function could result in a stack-based buffer overflow * CVE-2021-3998: Passing a path longer than PATH_MAX to the realpath function could result in a memory leak and potential access of uninitialized memory * CVE-2021-3999: Passing a buffer of size exactly 1 byte to the getcwd function may result in an off-by-one buffer underflow and overflow when the current working directory is longer than PATH_MAX and also corresponds to the / directory through an unprivileged mount namespace -
