Fix malloc alignment

2011-04-11T11:26:56+00:00

In commit 3e0a1f388, Richard tried to fix malloc alignments by using
 alignof (double __attribute_aligned__(sizeof (size_t))).
This doesn't work, since attribute_aligned overrides the alignment
rather than providing a minimum. On C6X, malloc returns four-byte
aligned values rather than the necessary eight-byte alignment.

It's simpler to use a comparison and pick the bigger of the two values,
so that's what I've done.

malloc: fix race condition and other bugs in the no-mmu malloc

2009-12-19T21:53:32+00:00

Fixes multiple race conditions on mmb list. This was done by
making the mmb_heap_lock into a recursive lock and making the
regular heap_lock extend to cover the mmb heap handling.

Also move the new_mmb allocation up to before the mmb list is
iterated through to find the insertion point. When the mmb_heap
also runs out and needs to be extended when the regular heap is
just extended, the mmb list could be messed up.

nommu: use MAP_UNINITIALIZE for mallocs

2009-11-24T02:35:34+00:00

Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use
it to get real uninitialized memory on no-mmu systems.  This avoids a lot
of normally useless overhead involved in zeroing out all of the memory
(sometimes multiple times).

malloc: handle size overflows in realloc()

2009-10-15T23:47:12+00:00

The malloc() code checks the incoming size to make sure the header
adjustment doesn't cause overflow in the size storage.  Add the same
check to realloc() to catch stupid stuff like realloc(..., -1).
