Jérôme Gardou d8cdb89fb0 [NTOSKRNL] Overhaul Cc and Mm relationship
Previously, when creating a file section, Mm requested Cc to cache the file, then Cc would request pages from Mm, then Mm would request them back to serve its file-mapping role
Now, Mm does it all by itself. If file cahcing is requested by the FS driver, then Cc creates a file mapping and uses that to serve its purpose.

This is a rewrite of Cc

Timo Kreuzer d4b4cf7448 [NTOS:MM] Make sure PXEs/PPEs and PDEs are always MM_EXECUTE_READWRITE
This is required since the NX protection proagates from the highest level, enforcing NX on the entire range, independent of whether lower level P*Es have the bit set or not. It might be useful to add a platform specific constant to allow making page tables NX on architectures that have a different behavior.

Vadim Galyant 3c585d0e38
[NTOS:MM] Since the _MMPTE_SUBSECTION structure for x86 (without PAE) uses the SubsectionAddressLow truncated by the least significant three bits, the _CONTROL_AREA, _LARGE_CONTROL_AREA, _SUBSECTION, _MSUBSECTION structures must be 8-byte aligned.

[NTOS:MM] Get rid of unnecessary MmZeroingPageThreadActive. 2020-04-06 11:13:55 +02:00
Thomas Faber 5280deecfa
[NTOS:MM] Fix MmZeroingPageThreadActive race condition.
If a thread calls MiInsertPageInFreeList after the zero page thread has
woken up from its wait but before it acquired the PFN lock,
MmZeroingPageEvent might get set again even though there is no additional
work to be done.
By setting MmZeroingPageThreadActive together with the event, the variable
correctly indicates for future callers that the zero thread will process
newly added free pages.

This partially reverts r72990.

[NTOS] Just go ahead and allow printing all the printable ASCII characters in ExpTagAllowPrint().
As documented in https://docs.microsoft.com/fr-fr/windows-hardware/drivers/ddi/wdm/nf-wdm-exallocatepoolwithtag
pool tag "characters" must be a value in the range 0x20 (space) to 0x7E (tilde),
which happen indeed to be the range of printable (non-extended) ASCII characters.

(The display problem was originally caught while attempting to display
the pool tag 0x3a306847 corresponding to 'Gh0:', a win32ss GDIOBJ pool tag
encoded with macro GDIOBJ_POOL_TAG().)

[NTOS:KE/MM] Some bug-fixes in the bugcheck code.
- Introduce the MmMakeKernelResourceSectionWritable() helper for
  making the kernel resource memory section writable, and use it
  in KeGetBugMessageText(). Indeed, this latter function patches
  in place the bugcheck resource message to trim any trailing
  newlines before displaying the message on screen.

  See also https://github.com/osresearch/uxen/blob/83bad53/dm/introspection-win7.c#L286
  that mentions it too.

  This fixes bugcheck text display (e.g. the MANUALLY_INITIATED_CRASH one)
  when using (at least) MSVC-built ReactOS, avoiding a Page-Fault
  exception during the bugcheck.

- Cover KeGetBugMessageText() in SEH since we are accessing kernel
  resources that could also be corrupted in bugcheck scenarii, and we
  don't want to further bugcheck.

- Fix newline trimming loop.

- KiDoBugCheckCallbacks():
  * Wrap the bugcheck CallbackRoutine call in SEH.
  * Add a FIXME concerning the need of further memory validation of CurrentRecord.

- Add a FIXME concerning the need to run the bugcheck-reason callbacks
  with the KbCallbackReserved1 reason, in KeBugCheckWithTf().
