[BZ #14195]
* sysdeps/i386/i686/multiarch/strcmp-sssse3.S: Fix
segmentation fault for a case of two empty input strings.
* string/test-strncasecmp.c (check1): Renamed to...
(bz12205): ...this.
(bz14195): Add new testcase for two empty input strings and N > 0.
(test_main): Call new testcase, adapt for renamed function.
* malloc.c/arena.c (reused_arena): New parameter, avoid_arena.
When avoid_arena is set, don't retry in the that arena. Pick the
next one, whatever it might be.
(arena_get2): New parameter avoid_arena, pass through to reused_arena.
(arena_lock): Pass in new parameter to arena_get2.
* malloc/malloc.c (__libc_memalign): Pass in new parameter to
arena_get2.
(__libc_malloc): Unify retrying after main arena failure with
__libc_memalign version.
(__libc_valloc, __libc_pvalloc, __libc_calloc): Likewise.
Add support for STT_GNU_IFUNC symbols and the new R_390_IRELATIVE
relocation. Provide optimized version of memcpy, memset, and memcmp
for z10 and z196.
[BZ #13579] Do not free l_initfini and allow it to be reused
on subsequent dl_open calls for the same library. This fixes
the invalid memory access in do_lookup_x when the previously
free'd l_initfini was accessed through l_searchlist when a
library had been opened for the second time.
[BZ #13882]
* elf/dl-deps.c (_dl_map_object_deps): Fix cycle detection. Use
uint16_t for elements in the "seen" array to avoid char overflows.
* elf/dl-fini.c (_dl_sort_fini): Likewise.
* elf/dl-open.c (dl_open_worker): Likewise.
[BZ #14134]
When converting IBM930 code with iconv(), if IBM930 code which
includes invalid multibyte character "0xffff" is specified, then
iconv() segfaults. This is easy to see using the following command:
echo '0x0e 0x43 0x8c 0xff 0xff 0x43 0xbd 0x43 0xbd' | xxd -r |
iconv -f IBM930 -t UTF-8
[BZ #13743]
A new class of installed headers has been documented for low-level
platform-specific functionality. PowerPC added the first instance with a
function to provide time base register access (__ppc_get_timebase). This
is required for applications that measure time at high frequencies with
high precision that can't afford a syscall.
As of January 1st 2009, the "new" prefix was removed from the New
Turkish lira, its official name becoming "Turkish lira" again,
abbreviated "TL".
