From: Koen Vandeputte Date: Mon, 14 Oct 2019 12:51:23 +0000 (+0200) Subject: toolchain/musl: bump to version 1.1.24 X-Git-Tag: v19.07.0-rc1~57 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=00f96dcddb7717a8cd30e75ef38e7ec03adb0f6b;p=oweals%2Fopenwrt.git toolchain/musl: bump to version 1.1.24 1.1.24 release notes new features: - GLOB_TILDE extension to glob - non-stub catgets localization API, using netbsd binary catalog format - posix_spawn file actions for [f]chdir (extension, pending future standard) - secure_getenv function (extension) - copy_file_range syscall wrapper (Linux extension) - header-level support for new linux features in 5.2 performance: - new fast path for lrint (generic C version) on 32-bit archs major internal changes: - functions involving time are overhauled to be time64-ready in 32-bit archs - x32 uses the new time64 code paths to replace nasty hacks in syscall glue compatibility & conformance: - support for powerpc[64] unaligned relocation types - powerpc[64] and sh sys/user.h no longer clash with kernel asm/ptrace.h - select no longer modifies timeout on failure (or at all) - mips64 stat results are no longer limited to 32-bit time range - optreset (BSD extension) now has a public declaration - support for clang inconsistencies in wchar_t type vs some 32-bit archs - mips r6 syscall asm no longer has invalid lo/hi register clobbers - vestigial asm declarations of __tls_get_new are removed (broke some tooling) - riscv64 mcontext_t mismatch glibc's member naming is corrected bugs fixed: - glob failed to match broken symlinks consistently - invalid use of interposed calloc to allocate initial TLS - various dlsym symbol resolution logic errors - semctl with SEM_STAT_ANY didn't work - pthread_create with explicit scheduling was subject to priority inversion - pthread_create failure path had data race for thread count - timer_create with SIGEV_THREAD notification had data race getting timer id - wide printf family failed to support l modifier for float formats arch-specific bugs fixed: - x87 floating point stack imbalance in math asm (i386-only CVE-2019-14697) - x32 clock_adjtime, getrusage, wait3, wait4 produced junk (struct mismatches) - lseek broken on x32 and mipsn32 with large file offsets - riscv64 atomics weren't compiler barriers - riscv64 atomics had broken asm constraints (missing earlyclobber flag) - arm clone() was broken when compiled as thumb if start function returned - mipsr6 setjmp/longjmp did not preserve fpu register state correctly Refreshed all patches. Removed upstreamed.

-Using common code path for all symbol lookups fixes three dlsym issues: - -- st_shndx of STT_TLS symbols were not checked and thus an undefined - tls symbol reference could be incorrectly treated as a definition - (the sysv hash lookup returns undefined symbols, gnu does not, so should - be rare in practice). - -- symbol binding was not checked so a hidden symbol may be returned - (in principle STB_LOCAL symbols may appear in the dynamic symbol table - for hidden symbols, but linkers most likely don't produce it). - -- mips specific behaviour was not applied (ARCH_SYM_REJECT_UND) so - undefined symbols may be returned on mips. - -always_inline is used to avoid relocation performance regression, the -code generation for find_sym should not be affected. ---- -

-commit 31c5fb80b9eae86f801be4f46025bc6532a554c5 introduced underflow -code paths for the i386 math asm, along with checks on the fpu status -word to skip the underflow-generation instructions if the underflow -flag was already raised. unfortunately, at least one such path, in -log1p, returned with 2 items on the x87 stack rather than just 1 item -for the return value. this is a violation of the ABI's calling -convention, and could cause subsequent floating point code to produce -NANs due to x87 stack overflow. if floating point results are used in -flow control, this can lead to runaway wrong code execution. - -rather than reviewing each "underflow already raised" code path for -correctness, remove them all. they're likely slower than just -performing the underflow code unconditionally, and significantly more -complex. - -all of this code should be ripped out and replaced by C source files -with inline asm. doing so would preclude this kind of error by having -the compiler perform all x87 stack register allocation and stack -manipulation, and would produce comparable or better code. however -such a change is a much larger project. ---- -
