| | | | | | | | malloc implementation). Fix problem reported to bugtraq about problems with integer overflow that can occur during the computation of the memory region size by calloc (and similar functions) which could result in a subsequent buffer overflow. -Erik

* Redo the locking, so that it may actually work. Now locking is done atMiles Bader2002-07-258-130/+186
| | | | | | | | | 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.
* Factor out some common code sequences into inline functions.Miles Bader2002-07-242-53/+74

* * Automatically try to unmap heap free-areas when they get very big.Miles Bader2002-07-238-190/+234
| | | | | | | | * 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.
* Doc fix.Miles Bader2002-07-195-5/+5

* Rename mutex stuff to use heap-specific names.Miles Bader2002-07-195-24/+26
| | | | Doc fix.
* Miles Bader implemented a new mmap based malloc which is muchEric Andersen2002-07-1813-1169/+740
| | | | | | | 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!

* Ok, this should finish off my massive ro-organization. The sourceEric Andersen2001-05-121-2/+1
| | | | | | | | | tree is less messy now (which helps), all libraries are placed into uClibc/lib when compiling, all libraries now use a consistant mechanism for being built, all libraries use a consistant naming scheme where the lib name includes the uClibc version number, which makes ldconfig happy and willing to work with us. -Erik
* A patch from Matthias Kilian <kili@outback.escape.de> to fix -DDEBUG_MALLOCEric Andersen2001-05-112-1/+12
| | | | | so that it works for realloc too. -Erik
* Fix up breakage resulting from flipping the sense of some defines. Change fromEric Andersen2001-03-191-9/+10
| | | | | | | | defining things to "0" in the disabled case to outright undefining them, lest code that does an "#ifdef FOO" get inadvertantly triggered. Remove now unneeded lines from Rules.mak which makes the command line smaller and avoids redundancy (since this stuff is now pulled in via features.h). -Erik
* Update to "malloc" so it will work on CPUs not supporting non-aligned words.Eric Andersen2001-02-211-7/+35

* Patch from James Graves <jgraves@deltamobile.com> to better handle m68k.Eric Andersen2001-01-121-2/+13
| | | | | | Also fixes 2 very important malloc bugs! Anyone using malloc (esp mmu-less) should update and recompile. -Erik
* Update makefile to match the new malloc codeEric Andersen2001-01-121-6/+8

* Manuel Novoa III modified malloc.c and avlmacro.h to reduce code size byEric Andersen2001-01-123-610/+731
| | | | | using functions instead on Inlining (size vas speed tradeoff). I ran the results through indent. Looking pretty good IMHO.
