2013-11-21Use __glibc_block in public headers.Meador Inge1-1/+1
As detailed in PR11157, the use of '__block' is known to interfere with keywords in some environments, such as the Clang -fblocks extension. Recently a similar issue was raised concerning the use of '__unused' and a '__glibc' prefix was proposed to create a glibc implementation namespace for these sorts of issues [1]. This patches takes that approach. [1] https://sourceware.org/ml/libc-alpha/2012-02/msg00047.html [2] http://lists.debian.org/debian-glibc/2013/11/msg00020.html
2013-11-20Consolidate valloc/pvalloc code.Ondřej Bílka2-109/+33
To make malloc code more maintainable we make malloc and pvalloc share logic with memalign.
2013-11-01Fix malloc_info statistic. Fixes bug 16112Ondřej Bílka1-16/+4
2013-10-30malloc: Fix for infinite loop in memalign/posix_memalign.Will Newton4-0/+41
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.

2013-10-10malloc/hooks.c: Correct check for overflow in memalign_check.Will Newton1-4/+7
A large value of bytes passed to memalign_check can cause an integer overflow in _int_memalign and heap corruption. This issue can be exposed by running tst-memalign with MALLOC_CHECK_=3. ChangeLog: 2013-10-10 Will Newton <will.newton@linaro.org> * malloc/hooks.c (memalign_check): Ensure the value of bytes passed to _int_memalign does not overflow.

2013-05-15Move _obstack_compat out of commonPeter Collingbourne1-1/+1
it is impossible to create an alias of a common symbol (as compat_symbol does), because common symbols do not have a section or an offset until linked. GNU as tolerates aliases of common symbols by simply creating another common symbol, but other assemblers (notably LLVM's integrated assembler) are less tolerant. 2013-05-15 Peter Collingbourne <pcc@google.com> * malloc/obstack.c (_obstack_compat): Add initializer. -

2013-01-17Add HAVE_MREMAP for mremap usagePino Toscano2-11/+4
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.

2012-11-19muntrace: reset file and hooks before finalizing the streamPino Toscano1-2/+7
fclose will call free, invoking its hook, then fprintf which would indirectly try to allocate a buffer, and this can cause malloc to be used (thus its hook to be invoked) if libio uses malloc instead of mmap; given any malloc/free hook locks the internal lock, this leads to a deadlock. To prevent this hook roundtrip at muntrace, first unset MALLSTREAM and the hooks, and only after that close the trace file.
