This is a new version (0.10) of the kernel memory leak detector. See the Documentation/kmemleak.txt file for a more detailed description. The patches are downloadable from (the whole patch or the broken-out series):
http://homepage.ntlworld.com/cmarinas/kmemleak/patch-2.6.18-rc6-kmemleak-0.10.bz2 http://homepage.ntlworld.com/cmarinas/kmemleak/broken-out/patches-kmemleak-0.10.tar.bz2
What's new in this version:
- replaced the pointers radix tree with a hash table to avoid the locking dependencies caused by the radix tree memory allocations - fixed locking dependency problems by no longer holding the memleak_lock when allocating/freeing memory from kmemleak and also using RCU - changed the naming of tracked memory blocks from "pointer" to "object" - code clean-up
To do:
- testing on a wider range of platforms and configurations - support for ioremap tracking (once the generic ioremap patches are merged) - eliminate the task stacks scanning (if possible, by marking the allocated blocks as temporary until the return to user-space - Ingo's suggestion) - precise type identification (after first assessing the efficiency of the current method as it requires changes to the kernel API)
