| H A D | VMUserAddressSpace.h | diff d62afe7a Wed Apr 28 16:06:40 MDT 2010 Ingo Weinhold <ingo_weinhold@gmx.de> VMUserAddressSpace::LookupArea(): Although only a read-lock is the precondition for calling the function it read/write accessed the fAreaHint attribute in a non-atomic manner. I.e. if executed concurrently by two threads of the same team one could return the wrong area. The most likely problem could be caused in vm_soft_fault(), leading to pages being added to the wrong caches. The bug itself is inherited from NewOS, but is triggered way more likely since the page daemon unmaps inactive pages (r35485). Probably fixes #5413. Might also fix the sporadically occurring crashes/asserts in the hoard allocator -- at least inactive pages being replaced by zeroed ones would be an excellent explanation.
