* 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.

| | | | | | | | | | | | | 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.

* muntrace: reset file and hooks before finalizing the streamPino Toscano2012-11-191-2/+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.

* Shrink heap on linux when overcommit_memory == 2Siddhesh Poyarekar2012-09-251-3/+6
| | | | | | | | | | | | | Using madvise with MADV_DONTNEED to release memory back to the kernel is not sufficient to change the commit charge accounted against the process on Linux. It is OK however, when overcommit is enabled or is heuristic. However, when overcommit is restricted to a percentage of memory setting the contents of /proc/sys/vm/overcommit_memory as 2, it makes a difference since memory requests will fail. Hence, we do what we do with secure exec binaries, which is to call mmap on the region to be dropped with MAP_FIXED. This internally unmaps the pages in question and reduces the amount of memory accounted against the process.
