Siddhesh Poyarekar 62a5881678 Fix formatting in malloc_info 2014-05-30 22:44:45 +05:30
Siddhesh Poyarekar 4d653a59ff Add mmap usage in malloc_info output
The current malloc_info xml output only has information about
allocations on the heap.  Display information about number of mappings
and total mmapped size to this to complete the picture.

Ondřej Bílka 987c02692a Remove mi_arena nested function. 2014-05-30 13:25:43 +02:00
Ondřej Bílka 20c138997a revert commit fdfd175d46 2014-05-30 13:23:39 +02:00
Carlos O'Donell fdfd175d46 Remove nested function mi_arena from malloc_info.
The nested function mi_arena was removed from malloc_info
and made into a non-nested static inline function of the same
name with the correct set of arguments passed from malloc_info.
This enables building glibc with compilers that don't support
nested functions. Future work on malloc_info should remove these
functions entirely to support JSON format output. Therefore we
do the minimum required to remove the nested function.

Will Newton 439bda3209 malloc: Fix MALLOC_DEBUG -Wundef warning
MALLOC_DEBUG is set optionally on the command line. Default the value
to zero if it is not set on the command line, and test its value
with #if rather than #ifdef. Verified the code is identical before
and after this change apart from line numbers.

ChangeLog:

2014-04-11  Will Newton  <will.newton@linaro.org>

	* malloc/malloc.c [!MALLOC_DEBUG]: #define MALLOC_DEBUG
	to zero if it is not defined elsewhere.  (mtrim): Test
	the value of MALLOC_DEBUG with #if rather than #ifdef.

Carlos O'Donell d6285c9f0b Revert 4248f0da6f.
Objections were raised surrounding the calloc simplification
and it is better to revert the patch, continue discussions
and then submit a new patch for inclusion with all issues
fully addressed.

Ondřej Bílka 4248f0da6f Simplify calloc implementation.
To make future improvements of allocator simpler we could for now calloc
just call malloc and memset. With that we could omit a changes that
would duplicate malloc changes anyway.

Maxim Kuvyrkov 362b47fe09 Fix race in free() of fastbin chunk: BZ #15073
Perform sanity check only if we have_lock.  Due to lockless nature of fastbins
we need to be careful derefencing pointers to fastbin entries (chunksize(old)
in this case) in multithreaded environments.

The fix is to add have_lock to the if-condition checks.  The rest of the patch
only makes code more readable.

	* malloc/malloc.c (_int_free): Perform sanity check only if we
	have_lock.

Will Newton 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.

Siddhesh Poyarekar 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.
