toolchain/musl: add support for renameat2()

2024-06-13T12:16:32Z

Backport an upstream patch to support the renameat2 syscall, added in Linux 3.15 and supported by glibc since 2.28. It is commonly used in filesystem or security contexts, and needed building upstream kernel bpf selftests.

toolchain/musl: fix loongarch64 ldso file name

2024-05-04T06:12:56Z

GCC has changed musl dynamic linker name from ld-musl-loongarch-lp64d.so.1 to ld-musl-loongarch64.so.1 recently [1]. This means there are two dynamic linker names will be used across different ersions of GCC. But musl 1.2.5 only supports the new name while the GCC we're currently using uses the old name. To maintain compatibility with all versions of GCC, the musl is then patched to generate two symbolic links to libc.so with both old and new names.

toolchain/musl: Update to 1.2.5

2024-04-14T15:38:09Z

Update musl C library to 1.2.5 This release adds extension functions statx and preadv2/pwritev2, with fallback implementations for older kernels, and adds two new ports: loongarch64 and riscv32. Minor changes to the printf family of functions have been made for conformance to new standards interpretations/requirements. TLSDESC support for riscv64 has also been added. Bugs fixed include some DNS issues related to new TCP fallback functionality, several rare race conditions, potentially incorrect return value when glob aborts, and several signifiant arch-specific bugs affecting TLSDESC on arm, riscv64 icache flushing, and sh sigsetjmp and dlsym RTLD_NEXT. 1.2.5 release notes: new features: - statx function (linux extension; via syscall and fallback using fstatat) - clone function is now usable and gives _Fork-like consistency in child - statvfs now provides f_type result - preadv2 and pwritev2 (linux extension) syscall wrappers - riscv64 TLSDESC support new ports: - loongarch64 - riscv32 compatibility: - DNS resolver can now handle answers with long CNAME chains - string.h no longer provides (C23-incompat) non-prototype decl of basename - fstatat statx backend now matches stat syscall non-automounting behavior - mntent interfaces now handle escaped whitespace in paths/options standards updates: - printf %lc of nul wchar now produces output - snprintf and swprintf no longer fail on n > INT_MAX - ppoll is now exposed in default feature profile bugs fixed: - some long DNS answers were wrongly rejected despite new TCP support - glob could wrongly return GLOB_NOMATCH if aborted before any matches - multithreaded set*id could malfunction from thread sequencing logic bug - certain use of threads after fork could deadlock thread-list lock - posix_spawn child could deadlock in race with async parent death - mbrtowc return value was wrong if argument n exceeded UINT_MAX - 80-bit extended acoshl and powl got some corner cases wrong - syslog incorrectly generated localized timestamps arch-specific bugs fixed: - arm (32-bit) TLSDESC malfunctioned due to addends being processed wrong - riscv64 icache flush operation was non-functional - sh sigsetjmp failed to properly restore call-saved register r8 on return - sh dlsym RTLD_NEXT did not identify calling module correctly Signed-off-by: Hannu Nyman [Removed patch adding basename hack again] Signed-off-by: Hauke Mehrtens
