2013-11-28Make memset in calloc a tail call.Ondřej Bílka
2013-11-21Add missing #include for malloc/hooks.c code.Roland McGrath
2013-11-20Consolidate valloc/pvalloc code.Ondřej Bílka
To make malloc code more maintainable we make malloc and pvalloc share logic with memalign.
2013-11-01Fix malloc_info statistic. Fixes bug 16112Ondřej Bílka
2013-10-30malloc: Fix for infinite loop in memalign/posix_memalign.Will Newton
A very large alignment argument passed to mealign/posix_memalign causes _int_memalign to enter an infinite loop. Limit the maximum alignment value to the maximum representable power of two to prevent this from happening. Changelog: 2013-10-30 Will Newton <will.newton@linaro.org> [BZ #16038] * malloc/hooks.c (memalign_check): Limit alignment to the maximum representable power of two. * malloc/malloc.c (__libc_memalign): Likewise. * malloc/tst-memalign.c (do_test): Add test for very large alignment values. * malloc/tst-posix_memalign.c (do_test): Likewise.

2013-09-11malloc: Check for integer overflow in memalign.Will Newton
A large bytes parameter to memalign could cause an integer overflow and corrupt allocator internals. Check the overflow does not occur before continuing with the allocation. ChangeLog: 2013-09-11 Will Newton <will.newton@linaro.org> [BZ #15857] * malloc/malloc.c (__libc_memalign): Check the value of bytes does not overflow.

2013-06-08Use (void) in no-arguments function definitions.Joseph Myers
2013-03-08Remove __malloc_ptr_t.Joseph Myers
2013-01-17Add HAVE_MREMAP for mremap usagePino Toscano
Introduce (only on Linux) and use a HAVE_MREMAP symbol to advertize mremap availability. Move the malloc-sysdep.h include from arena.c to malloc.c, since what is provided by malloc-sysdep.h is needed earlier in malloc.c, before the inclusion of arena.c.

2012-09-05Don't change no_dyn_threshold on mallopt failureAlexandre Oliva
* malloc/malloc.c (__libc_mallopt) <M_MMAP_THRESHOLD>: Do not change internal state upon failure.
2012-09-05Return requested size for malloc_usable_size when MALLOC_CHECK_ > 0Siddhesh Poyarekar
[BZ #1349] malloc_usable_size returns the usable size in an allocated chunk, which may be >= the requested size. In the case of MALLOC_CHECK_ being exported to > 0 however, only the requested size is usable, since a magic value is written at the end of the request size to trap writes beyond request bounds. Hence, when MALLOC_CHECK_ is exported to > 0, malloc_usable_size() should return the request size.

2012-08-10 [BZ #13939]Jeff Law

(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.
