* Fix race in free() of fastbin chunk: BZ #15073Maxim Kuvyrkov2013-12-241-8/+12
| | | | | | | | | | | | Perform sanity check only if we have_lock. Due to lockless nature of fastbins we need to be careful derefencing pointers to fastbin entries (chunksize(old) in this case) in multithreaded environments. The fix is to add have_lock to the if-condition checks. The rest of the patch only makes code more readable. * malloc/malloc.c (_int_free): Perform sanity check only if we have_lock.

* Use __glibc_block in public headers.Meador Inge2013-11-211-1/+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
* Consolidate valloc/pvalloc code.Ondřej Bílka2013-11-202-109/+33

* malloc: Fix for infinite loop in memalign/posix_memalign.Will Newton2013-10-304-0/+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.

* malloc/hooks.c: Correct check for overflow in memalign_check.Will Newton2013-10-101-4/+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.

* Move _obstack_compat out of commonPeter Collingbourne2013-05-151-1/+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. -
