* 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.

* Cleanup code duplication in malloc on fallback to use another arenaSiddhesh Poyarekar2012-09-072-75/+32
| | | | | Break the fallback code to try another arena into a separate function for readability.

| | | | | | * malloc/mcheck.c (mcheck_check_all): Fix typo. * malloc/memusage.c (mmap): Likewise. (mmap64, mremap): Likewise. Adjust name in comment.
* Return requested size for malloc_usable_size when MALLOC_CHECK_ > 0Siddhesh Poyarekar2012-09-054-5/+86
| | | | | | | | | | | [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.

* [BZ #13939]Jeff Law2012-08-102-27/+45
| | | | | | | | | | | | | * 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.

* Fix tst-obprintf - and mcheck in generalAndreas Jaeger2012-05-031-0/+6
| | | | | | | | | | | | | | | | tst-obprintf failed with GCC 4.7. It turned out that this is the fault of GCC optimizing away the following from malloc/mcheck.c: /* We call malloc() once here to ensure it is initialized. */ void *p = malloc (0); free (p); gcc sees the malloc(0);free pair and removes it completely. And now malloc is not properly initialized and we screw up if both mcheck is used (via tst-obprintf) and MALLOC_CHECK_ is set (as it is in my environment).
