| 2015-03-18 | malloc: checked_request2size failure deadlocks | Zhiqiang Zhang | |
| For some rarely cases(almost App bugs), calling malloc with a very largre size, checked_request2size check will fail,set ENOMEM, and return 0 to caller. But this will let __malloc_lock futex locked and owned by the caller. In multithread circumstance, other thread calling malloc/calloc will NOT succeed and get locked.

| 2006-12-07 | Major cleanup of internal mutex locking. Be more consistant in how we do | Eric Andersen | |
| things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking. | |||

| 2003-12-30 | Rework malloc. The new default implementation is based on dlmalloc from Doug | Eric Andersen | |
| Lea. It is about 2x faster than the old malloc-930716, and behave itself much better -- it will properly release memory back to the system, and it uses a combination of brk() for small allocations and mmap() for larger allocations. -Erik | |||
