* * elf/dl-close.c: Include stddef.h.Ulrich Drepper2005-04-271-8/+37
| | | | | | | | | | | | | | | | | | | | | | | | | (_dl_close): If called recursively, just remember GC needs to be rerun and decrease l_direct_opencount. Avoid GC if l_direct_opencount decreased to 1. Rerun GC at the end if any destructor unloaded some additional libraries. * elf/Makefile: Add rules to build and run unload6 test. * elf/unload6.c: New test. * elf/unload6mod1.c: New file. * elf/unload6mod2.c: New file. * elf/unload6mod3.c: New file. * malloc/hooks.c (mem2chunk_check): Add magic_p argument, set *magic_p if magic_p is not NULL. (top_check): Invoke MALLOC_FAILURE_ACTION if MORECORE failed. (malloc_check): Fail if sz == -1. (free_check): Adjust mem2chunk_check caller. (realloc_check): Likewise. Fail if bytes == -1. If bytes == 0 and oldmem != NULL, call free_check and return NULL. If reallocating and returning NULL, invert magic byte again to make oldmem valid region for further checking. (memalign_check): Fail if bytes == -1. * malloc/Makefile: Add rules to build and run tst-mcheck. * malloc/tst-mcheck.c: New test.

* [BZ #457]Ulrich Drepper2004-12-141-8/+14
| | | | | | | | | Update. 2004-10-19 Wolfram Gloger <wg@malloc.de> * malloc/hooks.c (mem2chunk_check, top_check): Handle non-contiguous arena. Reported by Michael Dalton <mwdalton@stanford.edu> [BZ #457]. Add further checks for top chunk.
* Update.Ulrich Drepper2004-09-091-1/+1
| | | | | | | | | | 2004-09-09 Ulrich Drepper <drepper@redhat.com> * malloc/hooks.c (top_check): Print top chunk corruption as normal error message. * malloc/malloc.c (malloc_printerr): Don't make informational message look like error message.
* Update.Ulrich Drepper2004-09-091-4/+4
| | | | | | | | * malloc/malloc.c (_int_free): Add inexpensive double free and memory corruption tests. (malloc_printf_nc): Renamed to malloc_printerr. Second parameter is no format string anymore. Don't use stdio. Adjust all callers. * malloc/hooks.c: Adjust malloc_printf_nc callers.
* Update.Ulrich Drepper2004-08-211-65/+6
| | | | | | | | | | | | | | * malloc/hooks.c (DEFAULT_CHECK_ACTION): Moved to malloc.c. (check_action): Likewise. When printing error messages, use malloc_printf_nc now instead of fiddling with the streams cancellation flag in every place. * malloc/malloc.c (DEFAULT_CHECK_ACTION): New definition. Change default to 3. (check_action): New variable. (unlink): Print error message and eventually terminate in case list is corrupted. (malloc_printf_nc): New function. Use it in _int_free. Change proposed by Arjan van de Ven.
