 2021-02-03 09:41:22 +01:00
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

Victor Perevertkin e18a32df3a
[NTOS:IO] Refactoring of the driver initialization code 
- Remove IopCreateDriver and put its code into IoCreateDriver and
  IopInitializeDriverModule. It's hard to extract a meaningful common
  part from it
- Refactor IopInitializeDriverModule. Extend and put the DriverName
  generation logic into it. Now this function frees the ModuleObject in
  case of failure and returns STATUS_FAILED_DRIVER_ENTRY in case of
  DriverInit failure (will be used later)

[NTOS:MM] Add a MmChangeKernelResourceSectionProtection() helper. (#1649) 
This allows setting the memory protection of the kernel's resource
section as will. MmMakeKernelResourceSectionWritable() is re-implemented
around this helper.
