[glibc] annotated tag glibc-2.42 created (now d7be9df5ad)

by git＠git.linaro.org

This is an automated email from the git hooks/post-receive script. unknown user pushed a change to annotated tag glibc-2.42 in repository glibc. at d7be9df5ad (tag) tagging d2097651cc57834dbfcaa102ddfacae0d86cfb66 (commit) replaces glibc-2.41.9000 tagged by Andreas K. Hüttel on Mon Jul 28 20:24:27 2025 +0200 - Log ----------------------------------------------------------------- The GNU C Library version 2.42 is now available The GNU C Library ================= The GNU C Library version 2.42 is now available. The GNU C Library is used as *the* C library in the GNU system and in GNU/Linux systems, as well as many other systems that use Linux as the kernel. The GNU C Library is primarily designed to be a portable and high performance C library. It follows all relevant standards including ISO C23 and POSIX.1-2024. It is also internationalized and has one of the most complete internationalization interfaces known. The GNU C Library website is at http://www.gnu.org/software/libc/ Packages for the 2.42 release may be downloaded from: http://ftpmirror.gnu.org/libc/ http://ftp.gnu.org/gnu/libc/ The mirror list is at http://www.gnu.org/order/ftp.html Distributions are encouraged to track the release/* branches corresponding to the releases they are using. The release branches will be updated with conservative bug fixes and new features while retaining backwards compatibility. NEWS for version 2.42 ===================== Major new features: * The following ISO C23 function families (introduced in TS 18661-4:2015) are now supported in <math.h>. Each family includes functions for float, double, long double, _FloatN and _FloatNx, and a type-generic macro in <tgmath.h>. - Power and absolute-value functions: compoundn, pown, powr, rootn, rsqrt. * On Linux, the pthread_gettid_np function has been added. * The ISO C2Y family of unsigned abs functions, i.e. uabs, ulabs, ullabs, and uimaxabs, is now supported. * On Linux, the <termios.h> interface now supports arbitrary baud rates; speed_t is redefined to simply be the baud rate specified as an unsigned int, which matches the kernel interface. * The thread-local cache in malloc (tcache) now supports caching of large blocks. This feature can be enabled by setting the tunable glibc.malloc.tcache_max to a larger value (max 4194304). Tcache is also significantly faster for small sizes. * A new configure option, "--enable-sframe", can be used to enable SFrame support of the GNU C Libraries. SFrame is a new stack trace information format which can be used by backtrace. It requires binutils with a minimum version of 2.45. * Support for lightweight stack guard pages via madvise and the MADV_GUARD_INSTALL flag has been added to pthread_create. * Additional optimized and correctly rounded mathematical functions have been imported from the CORE-MATH project, in particular acospif, asinpif, atanpif, atan2pif, cospif, sinpif, tanpif. * The testsuite has been significantly extended, including coverage of the functionality of the printf and scanf function families in many variants. * The manual has been significantly extended and updated, particularly the threads, terminal, filesystem, resource, and math chapters. * Code has been added to detect the x86-64 Intel Arrow Lake, Panther Lake, Clearwater Forest, and Diamond Rapids microarchitectures. * Regarding S390, support for the new z17 platform has been added. Deprecated and removed features, and other changes affecting compatibility: * The glibc.rtld.execstack tunable now supports a compatibility mode to allow programs that require an executable stack through dynamically loaded shared libraries. * On Linux, the <termio.h> header and the definition of struct termio in <sys/ioctl.h> have been removed. The termio interface has been obsolete since the very first version of POSIX.1 in 1988, replaced with <termios.h>. * The support for TX lock elision of pthread mutexes has been deprecated on all architectures and will be removed in the next release. * On AArch64 Linux targets supporting the Scalable Matrix Extension (SME), setjmp and sigsetjmp will disable the ZA state of SME. Changes to build and runtime requirements: * GCC 12.1 or later is now required to build the GNU C Library. * GNU Binutils 2.39 or later is now required to build the GNU C Library. Security related changes: The following CVEs were fixed in this release, details of which can be found in the advisories directory of the release tarball: GLIBC-SA-2025-0001: assert: Buffer overflow when printing assertion failure message (CVE-2025-0395) GLIBC-SA-2025-0003: power10: strcmp fails to save and restore nonvolatile vector registers (CVE-2025-5702) GLIBC-SA-2025-0004: power10: strncmp fails to save and restore nonvolatile vector registers (CVE-2025-5745) GLIBC-SA-2025-0005: posix: Fix double-free after allocation failure in regcomp (CVE-2025-8058) The following bugs were resolved with this release: [5994] stdio: fflush after ungetc on seekable input stream [12724] stdio: fclose violates POSIX 2008 on seekable input streams [25263] dynamic-link: ldd and ld.so fail to resolve $ORIGIN with cross dir symlink [27880] nptl: Please provide a pthread pid accessor [29190] dynamic-link: Symbols with version hash zero lead to crashes, not matched correctly [29459] stdio: fwrite does not return EPIPE when underlying write fails with EPIPE.
