ac3ed168d0 malloc: Remove check_action variable [BZ #21754]
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.

e863cce57b malloc: Remove malloc_get_state, malloc_set_state [BZ #19473]
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.

dea39b13e2 malloc: Correct malloc alignment on 32-bit architectures [BZ #6527]
After the heap rewriting added in commit
4cf6c72fd2 (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.

4cf6c72fd2 malloc: Rewrite dumped heap for compatibility in __malloc_set_state
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.

265cbed8e7 Fix for test "malloc_usable_size: expected 7 but got 11"
[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.

fff94fa224 Avoid deadlock in malloc on backtrace (BZ #16159)
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%).

a56ee40b17 malloc: Fix for infinite loop in memalign/posix_memalign.
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.

6ef9cc37f0 Return requested size for malloc_usable_size when MALLOC_CHECK_ > 0
[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.

9bf248c6c6 Correctly implement M_MXFAST.
* malloc/malloc.c (struct malloc_state): Replace max_fast with flags
	fields.
	(global_max_fast): New variable.
	(set_max_fast): Change to not require arena parameter and to modify
	global_max_fast.  Change all callers.
	(get_max_fast): New macro.  Use this instead of directly accessing
	now removed max_fast arena member.
	(have_fastchunks): Use flags instead of max_fast.
	(clear_fastchunks): Likewise.
	(set_fastchunks): Likewise.
	(contiguous): Likewise.
	(noncontiguous): Likewise.
	(set_noncontiguous): Likewise.
	(set_contiguous): Likewise.
	(malloc_init_state): Explicitly set FASTCHUNKS_BIT.  Call set_max_fast
	only for main arena.
	* malloc/hooks.c (public_sET_STATe): Adjust set_max_fast use.

bfc832ccf1 * elf/dl-close.c: Include stddef.h.
(_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.
