Sir Richard 83a2328786 [NTOS]: Blimey this was a hard one. When using the reserved flag to request 1MB in a new process (which is used for starting SMSS and CSRSS), we must request 1MB - 256 bytes (or any number, actually) to offset the fact that with a base address of 0x4, a 1MB region gets us at 0x100FFF, and not 0xFFFF, because Windows computes ending address *before* alignment, and then returns a new region size for you (so if you pass in 1MB, you get 1MB + 4096KB). In Win32csr, when the code is trying to release 1MB, this ended up in our "Case A", because it would still leave a page in the VAD. Fixed rtl to request just shy off a MB. Verified on Windows as well. ... [NTOS]: The fix above was due to fixing "EndingAddress" which was being initialized to zero too late (after writing to it!). This caused allocations with a fixed base address that were already on top of another allocation not to be seen as a conflict, then we tried inserting a VAD and received an ASSERT saying we've already found a VAD there. After fixing the sizing code, the bug above creeped up. Whoever wrote the NtFreeVirtualMemory test is a godsend. It has been nailing bug after bug in the VAD implementation. Thank you. svn path=/trunk/; revision=55990		2012-03-04 06:42:49 +00:00
