Release notes: new features: - large dns record lookups via tcp fallback - new getaddrinfo EAI_NODATA result to distinguish NODATA/NxDomain - support for new RELR compressed format for relative relocations - sysconf keys for querying signal stack size requirements - real vfork on riscv64 performance: - mallocng no longer uses MADV_FREE (high performance cost, little gain) - vdso clock_gettime is supported once again on 32-bit arm compatibility: - gethostbyname family now distinguishes NO_DATA from HOST_NOT_FOUND - res_send now works with caller-provided edns0 queries - arpa/nameser.h RR types list is now up-to-date - previously-missing POSIX confstr keys have been added - mntent interfaces now accept missing fields - alt signal stack, if any, is now used for internal signals - the LFS64 macros are no longer exposed without _LARGEFILE64_SOURCE - memmem (POSIX-future) is now exposed in default feature profile - pthread_atfork now admits calls from an application-provided malloc - debugger tracking of shared libraries now works on MIPS PIE binaries - sendmsg now supports up to SCM_MAX_FD fds in SCM_RIGHTS messages bugs fixed: - gethostbyname[2]_r wrongly returned nonzero (error) on negative result - parallel v4/v6 address queries could fail on query id collisions - spurious getaddrinfo/AI_ADDRCONFIG failures due to errno clobbering - dns search domains ending in dot (including lone dot) broke lookups - ipv6 servers in resolv.conf broke lookups on systems with v6 disabled - systems with bindv6only failed to query both v4 and v6 nameservers - res_mkquery mishandled consecutive final dots in name - res_send could malfunction for very small answer buffer sizes - resolver dns backend accepted answers with wrong (A vs AAAA) RR type - getservbyport_r returned junk or ENOENT (vs ERANGE) on buffer size errors - dns result parsing of malformed responses could process uninitialized data - freopen didn't reset stream orientation (byte/wide) & encoding rule - fwprintf didn't print most fields on open_wmemstream FILEs - wide printf %lc ignored field width - wide printf erroneously processed %n after encoding errors - use of wide printf %9$ argument slot overflowed undersized buffer - swprintf malfunctioned on nul character in output - strverscmp ordered digit sequences vs nondigits incorrectly - timer_create/SIGEV_THREAD failure leaked the thread - semaphores were subject to missed-wake under certain usage patterns - several possible rare deadlocks with lock handling at thread exit - several possible rare deadlocks with aio and multithreaded fork - dynamic linker relro processing was broken on archs w/variable pagesize - async cancellation could run cancellation handlers in invalid context - pthread_detach was wrongly a cancellation point in rare race code path - use-after-close/double-close errors in mq_notify error paths - mq_notify event thread wrongly ran with signals unmasked - wcs{,n}cmp, wmemcmp returned wrong results when difference overflowed - accept4, pipe2, and dup3 handled unknown flags wrong in fallback cases - CPU_SETSIZE macro had wrong unit - select fallback for pre-time64 kernels truncated timeout (vs clamping) arch-specific bugs fixed: - x32 new socketcalls took fallback path due to pointer sign extension - x32 wait4 didn't fill rusage structure (time64 regression) - x32 semtimedop mismatched timespec ABI with kernel (time64 regression) - sigaction signal mask was bogus on or1k, microblaze, mips, and riscv - powerpc-sf longjmp asm clobbered value argument - or1k poll function passed timeout to syscall in wrong form Removed upstreamed: - 800-mips_pie_debug.patch Manually rebased: - 600-nftw-support-common-gnu-extension.patch Signed-off-by: Linhui Liu <liulinhui36@gmail.com> |
