* malloc: handle size overflows in realloc()Mike Frysinger2009-10-161-0/+3
| | | | | | | | | | 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).

| | | | NPTL sh4 port build and work fine. All committed to allow Khem Ray working on a working branch to integrate the ARM nptl port. MIPS nptl port not tested but should still building and working fine. There are some other part non yet merged with trunk (misc/internals and some headers file that need some more work).

* Rework malloc. The new default implementation is based on dlmalloc from DougEric Andersen2003-12-302-2/+42
| | | | | | | 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
* Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III2003-12-272-4/+4
| | | | | | | | | | | | | | | | were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.
