Author: sir_richard Date: Mon Oct 18 14:25:33 2010 New Revision: 49194 URL: http://svn.reactos.org/svn/reactos?rev=49194&view=rev Log: [NTOS]: Store the protection mask in the Fake VADs as well, we can read/convert this from the MAREA protection value. [NTOS]: Reimplement NtQueryVirtualMemory to use VAD information instead. Even though Alloc/Free are still MAREA-based, the fake VADs we build ought to be enough to make the query API work for certain limited scenarios. Only some paths are implemented and it's lacking SEH, but it's good enough for the install/boot requirements. If there are any regressions, please file bugs.

Author: sir_richard Date: Mon Oct 18 13:10:54 2010 New Revision: 49193 URL: http://svn.reactos.org/svn/reactos?rev=49193&view=rev Log: [NTOS]: Complete the VAD-to-MAREA Synchronization hack by removing fake MAREAs that were added when inserting real VADs. To do this, we have to track the fake MAREA associated with a VAD, so we overload the FirstProtoTypePte field in the VAD, if this is NOT a section VAD (which we don't use yet). We'll figure something out for section VADs later. [NTOS]: Now that VAD and MAREA views are synchronized, remove the VAD limit and let VADs be created at any address. Also do not create an arbitrary 16MB VAD memory area anymore. This basically now allows for as many PEB/TEBs as can fit in the address space, fixing the recent known regression that limited the number of threads a process could have.
