- broken dynamic-model TLS in static-linked arm/mips/powerpc programs
0.9.13 release notes
new features:
- iconv support for EUC-KR and Big5 (including HKSCS) encodings
- field widths (POSIX 2008 feature) in strftime
- recurive rpath and $ORIGIN support in dynamic linker
- cpu affinity interfaces
- support for armhf (hardfloat) floating point environment (fenv)
- support for SSE fenv on i386 (for apps using -mfpmath=sse -msse2)
- strftime %s format (seconds since the epoch, future POSIX requirement)
- configure script now saves its command line as a comment in config.mak
- legacy functions valloc and euidaccess
performance:
- optimized asm memcpy for arm
- optimized asm memset for i386 and x86_64
- optimized C versions of memcpy and memset for all archs
- eliminated major spurious syscalls from posix_spawn
- some math asm for armhf (hardfloat)
workarounds for:
- qemu-user's rt_sigaction syscall does not allow old to alias new
- qemu-user's madvise always succeeds (broke pthread_getattr_np)
- passing PT_INTERP to dlopen attempted to double-load libc
- gcc 4.8.x generating self-referential (infinite recursion) memcpy/memset
- linux's lack of support for fchdir, fchmod, fchown, fstat on O_PATH fds
bugs fixed:
- failure to honor flags for fchmodat and faccessat (linux syscall api flaws)
- SIGEV_THREAD timer id corruption and race condition issues
- timer thread TLS incorrectly keeping values from previous expiry run
- ecvt/fcvt decimal position off-by-one
- in symbol-versioned libs, symbol resolved to oldest instead of newest
- posix_spawn not correctly reporting errno from exec failure
- "make install" was not atomic (overwrote files rather than replacing)
- integer overflows in strftime
- unset/empty TZ variable was mishandled
- strftime could crash if the struct tm did not have valid tm_zone field
- failure of fenv functions to handle invalid arguments (required by ISO C)
- failure of some math functions (C and i386 asm) to raise underflow flag
- broken dn_expand function (previously not used internally)
- race conditions with signals during fork
- incorrect access check in mktemp (obsolete function)
- unnecessary arbitrary limits on size of program headers in dynamic loader
- text formatting bugs in output of err.h functions
arch-specific bugs:
- fesetenv(FE_DFL_ENV) crashed on i386
- breakage of arm crt code when libc is compiled as thumb
- arm/armhf (hardfloat) misidentified by configure
- ambiguity of wait (exit status) macros on mips with signal number 127
- wrong value of _NSIG and SIGRTMAX on mips
