Date: Mon, 1 May 2023 23:47:32 -0400 From: Rich Felker <dalias@...c.org> To: musl@...ts.openwall.com Subject: musl 1.2.4 released This release adds TCP fallback to the DNS stub resolver, fixing the longstanding inability to query large DNS records and incompatibility with recursive nameservers that don't give partial results in truncated UDP responses. It also makes a number of other bug fixes and improvements in DNS and related functionality, including making both the modern and legacy API results differentiate between NODATA and NxDomain conditions so that the caller can handle them differently. On the API level, the legacy "LFS64" ("large file support") interfaces, which were provided by macros remapping them to their standard names (#define stat64 stat and similar) have been deprecated and are no longer provided under the _GNU_SOURCE feature profile, only under explicit _LARGEFILE64_SOURCE. The latter will also be removed in a future version. Builds broken by this change can be fixed short-term by adding -D_LARGEFILE64_SOURCE to CFLAGS, but should be fixed to use the standard interfaces. The dynamic linker (and static-PIE entry point code) adds support for the new compact "RELR" format for relative relocations which recent linkers can generate. Use of this linker feature for dynamic-linked programs will make them depend on having musl 1.2.4 or later available at runtime. Static-linkied PIE binaries using it, as always, are self-contained and have no such dependency. A large number of bugs have been fixed, including many in the wide printf family of functions, incorrect ordering of digits vs non-digits in strverscmp, and several rare race-condition corner cases in thread synchronization logic at thread exit time, in multi-threaded fork, pthread_detach, and POSIX semaphores. https://musl.libc.org/releases/musl-1.2.4.tar.gz https://musl.libc.org/releases/musl-1.2.4.tar.gz.asc Special thanks goes out to musl's release sponsors for supporting the project financially via Patreon and GitHub Sponsors at the $32/month level or higher: * Andrew Kelley / ziglang * Danny McClanahan * enduser * Eric Pruitt * Evan Phoenix * Greg Krimer * Hurricane Labs * Justin Cormack * Kentik * Laurent Bercot * Michael Sartain * Mirza Prasovic * Moinak Bhattacharyya * Nabu Casa * Nathan Hoad * Neal Gompa * Stackhero * Tyler James Frederick For information on becoming a sponsor, visit one of: https://github.com/sponsors/richfelker https://patreon.com/musl
