2017-08-31malloc: Change top_check return type to voidFlorian Weimer1-14/+12
After commit ec2c1fcefb200c6cb7e09553f3c6af8815013d83, (malloc: Abort on heap corruption, without a backtrace), the function always returns 0.
2017-08-30malloc: Remove check_action variable [BZ #21754]Florian Weimer1-50/+5
Clean up calls to malloc_printerr and trim its argument list. This also removes a few bits of work done before calling malloc_printerr (such as unlocking operations). The tunable/environment variable still enables the lightweight additional malloc checking, but mallopt (M_CHECK_ACTION) no longer has any effect.

This change allows us to change the encoding of these struct members in a centralized fashion.
2016-10-26malloc: Remove malloc_get_state, malloc_set_state [BZ #19473]Florian Weimer1-49/+14
After the removal of __malloc_initialize_hook, newly compiled Emacs binaries are no longer able to use these interfaces. malloc_get_state is only used during the Emacs build process, so we provide a stub implementation only. Existing Emacs binaries will not call this stub function, but still reference the symbol. The rewritten tst-mallocstate test constructs a dumped heap which should approximates what existing Emacs binaries pass to glibc malloc.

2016-05-24malloc: Correct malloc alignment on 32-bit architectures [BZ #6527]Florian Weimer1-1/+1
After the heap rewriting added in commit 4cf6c72fd2a482e7499c29162349810029632c3f (malloc: Rewrite dumped heap for compatibility in __malloc_set_state), we can change malloc alignment for new allocations because the alignment of old allocations no longer matters. We need to increase the malloc state version number, so that binaries containing dumped heaps of the new layout will not try to run on previous versions of glibc, resulting in obscure crashes. This commit addresses a failure of tst-malloc-thread-fail on the affected architectures (32-bit ppc and mips) because the test checks pointer alignment.
2016-05-13malloc: Rewrite dumped heap for compatibility in __malloc_set_stateFlorian Weimer1-100/+50
This will allow us to change many aspects of the malloc implementation while preserving compatibility with existing Emacs binaries. As a result, existing Emacs binaries will have a larger RSS, and Emacs needs a few more milliseconds to start. This overhead is specific to Emacs (and will go away once Emacs switches to its internal malloc). The new checks to make free and realloc compatible with the dumped heap are confined to the mmap paths, which are already quite slow due to the munmap overhead. This commit weakens some security checks, but only for heap pointers in the dumped main arena. By default, this area is empty, so those checks are as effective as before.
2016-02-19malloc: Remove max_total_mem member form struct malloc_parFlorian Weimer1-1/+1
Also note that sumblks in struct mallinfo is always 0. No functional change.

2015-05-19Fix for test "malloc_usable_size: expected 7 but got 11"James Lemke1-24/+38
[BZ #17581] The checking chain of unused chunks was terminated by a hash of the block pointer, which was sometimes confused with the chunk length byte. We now avoid using a length byte equal to the magic byte.
2015-05-19Avoid deadlock in malloc on backtrace (BZ #16159)Siddhesh Poyarekar1-4/+8
When the malloc subsystem detects some kind of memory corruption, depending on the configuration it prints the error, a backtrace, a memory map and then aborts the process. In this process, the backtrace() call may result in a call to malloc, resulting in various kinds of problematic behavior. In one case, the malloc it calls may detect a corruption and call backtrace again, and a stack overflow may result due to the infinite recursion. In another case, the malloc it calls may deadlock on an arena lock with the malloc (or free, realloc, etc.) that detected the corruption. In yet another case, if the program is linked with pthreads, backtrace may do a pthread_once initialization, which deadlocks on itself. In all these cases, the program exit is not as intended. This is avoidable by marking the arena that malloc detected a corruption on, as unusable. The following patch does that. Features of this patch are as follows: - A flag is added to the mstate struct of the arena to indicate if the arena is corrupt. - The flag is checked whenever malloc functions try to get a lock on an arena. If the arena is unusable, a NULL is returned, causing the malloc to use mmap or try the next arena. - malloc_printerr sets the corrupt flag on the arena when it detects a corruption - free does not concern itself with the flag at all. It is not important since the backtrace workflow does not need free. A free in a parallel thread may cause another corruption, but that's not new - The flag check and set are not atomic and may race. This is fine since we don't care about contention during the flag check. We want to make sure that the malloc call in the backtrace does not trip on itself and all that action happens in the same thread and not across threads. I verified that the test case does not show any regressions due to this patch. I also ran the malloc benchmarks and found an insignificant difference in timings (< 2%). * malloc/Makefile (tests): New test case tst-malloc-backtrace. * malloc/arena.c (arena_lock): Check if arena is corrupt.

2013-10-30malloc: Fix for infinite loop in memalign/posix_memalign.Will Newton1-0/+8
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.

2012-09-05Return requested size for malloc_usable_size when MALLOC_CHECK_ > 0Siddhesh Poyarekar1-1/+30
[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.
