* malloc: fix race condition and other bugs in the no-mmu mallocFreeman Wang2009-12-191-3/+3
| | | | | | | | | | | | | | 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.

| | | | | | | | | __UCLIBC_UCLINUX_BROKEN_MUNMAP__ (which is currently not defined anywhere). This makes other cases a tiny bit less efficient too. * Move the malloc lock into the heap structure (locking is still done at the malloc level though, not by the heap functions). * Initialize the malloc heap to contain a tiny initial static free-area so that programs that only do a very little allocation won't ever call mmap.

| | | | | | | | | the malloc/free level, not within the heap abstraction, and there's a separate lock to control sbrk access. Also, get rid of the separate `unmap_free_area' function in free.c, and just put the code in the `free' function directly, which saves a bunch of space (even compared to using an inline function) for some reason.

| | | | | | | | * Instead of using mmap/munmap directly for large allocations, just use the heap for everything (this is reasonable now that heap memory can be unmapped). * Use sbrk instead of mmap/munmap on systems with an MMU.

* Miles Bader implemented a new mmap based malloc which is muchEric Andersen2002-07-181-0/+35
smarter than the old "malloc-simple", and actually works, unlike the old "malloc". So kill the old "malloc-simple" and the old "malloc" and replace them with Miles' new malloc implementation. Update Config files to match. Thanks Miles!
