Timo Kreuzer	65dbfc2868	[NTOS:Mm] Rewrite MiWriteProtectSystemImage (#749) ... * The previous version was overcomplicated and broken and therefore disabled. * The new version also enforces NX protection on x64. * Now that protecting works, also protect the boot loaded images.	2019-01-18 22:11:43 +01:00

Timo Kreuzer	3021c2d571	[NTOS:MM] Pass page fault code to MmAccessFault ... Note: before we had a BOOLEAN parameter called StoreInstruction, but in reality it was not specifying whether the fault was from a store store instruction, but whether it was an access violation rather than a page-not-present fault. On x86 without PAE there are only 2 kinds of access violations: (1) Access of a kernel mode page from user mode, which is handled early and (2) access of a read-only (or COW) page with a writing instruction. Therefore we could get away with this, even though it relied on the wrong assumption that a fault, which was not a page-not-present-fault, was automatically a write access. This commit only changes one thing: we pass the full fault-code to MmAccessFault and handle the rest from there in exactly the same way as before. More changes are coming to make things clear.	2018-01-06 18:20:24 +01:00
