* malloc-standard: synchronize on forkTimo Teräs2011-12-231-0/+17
| | | | | | | | Otherwise other threads can leave malloc state locked, and the child will hang indefinitely if it tries to malloc something. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Natanael Copa <ncopa@alpinelinux.org>
* stdlib: fix arc4random return type to u_int32_tTimo Teräs2011-12-231-1/+2
| | | | | | | | | | | | | It's documented to be u_int32_t and not uint32_t: http://www.manpagez.com/man/3/arc4random/ This also fixes a major bug that stdlib.h includes stdint.h. Things might go very wrong because stdint.h has conditional defines and if stdlib.h is included before #define's for stdint.h we end up missing things and breaking builds (e.g. openjdk).

* Fix malloc alignmentBernd Schmidt2011-04-112-3/+5
| | | | | | | | | | | | | 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. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com>

| | | | | | | | | | The 0.9.31 release included a change to malloc-simple to request uninitialized memory from noMMU kernels. Unfortunately, the corresponding calloc() code assumed that memory returned by malloc() was already zeroed, which leads to all kinds of nastiness. Signed-off-by: Steven J.

| * malloc: fix race condition and other bugs in the no-mmu mallocFreeman Wang2009-12-192-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
