This PDO is created only once during start of first FDO.
Other buses will remain in an inactive state until
the first FDO receives a remove request.
CORE-17034
- Add SAL2 annotations.
- Use RTL_NUMBER_OF macro in kernel mode.
- Use better function/member names.
- Less hardcoded values.
- Add license information. See commit
d9face83c6 for details.
No functional changes.
I am not sure why this line was added.
I don't know how I could improve that case.
Then, disable it, for the time being.
Addendum to 4b9cf2e (r71252). CORE-12441 CORE-17371
Some virtual machines errorneously expose null PCI device function
on PIIX4 chipset where an USB controller should normally reside.
Windows pci.sys driver does not enumerate these devices.
Affected virtual machines:
- Connectix Virtual PC 5.1.370
- Connectix Virtual PC 5.2.418
- Microsoft Virtual PC 2004 SP1 (5.3.582.27)
- Microsoft Virtual PC 2007 SP1 (6.0.156.0)
Non-affected virtual machines:
- Connectix Virtual PC 4.0
- Microsoft Hyper-V
Fixes CORE-17636.
in CreateDIBPalette() when passing invalid arguments to CreateDIBSection.
This could be triggered by using the broken test-application "GDIProg".
After this patch not only the BSOD is fixed but also the app does
properly start up, like it is the case on 2k3sp2.
Thanks to the patches author Doug Lyons.
This splits MM_MAX_PAGE into the maximum addressable PFN (which is 2^20-1 on x86, 2^26-1 on x86PAE and 2^36-1 on x64) and the maximum mapped/accessible virtual memory MM_MAX_PAGE_LOADER (which is 4 GB on x86, since paging is disabled, but only 1 GB on x64, since only that much is identity-mapped).
- Remove a redundant call of ObReferenceObjectByHandle. Not only it didn't make much sense (we reference the object from thread handle and the new thread object referencing the same handle!), specifying a request access of THREAD_ALL_ACCESS for the thread object is kind of suspicious and all of these access rights are unwanted.
- Add some failure checks involving the CopyOnOpen code paths
- Add some DPRINT1 debug prints (concerning the CopyOnOpen code paths as usual)
* Fix some broken code
* Add some ASSERTs
* Use ApicWriteIORedirectionEntry where appropriate
* Use KeQueryInterruptHandler/KeRegisterInterruptHandler to save/restore the old handler instead of saving the KIDTENTRY
* Move HalpProfileInterruptHandler to apictimer.c and implement it
* Use READ/WRITE_REGISTER macros
* Add some symbolic names
driverName.Buffer leaked when the "(!NT_SUCCESS(status) || ServiceName != NULL)"
case is taken because ServiceName != NULL, and some of the functions fail.
- Fix CID 1477246: Uninitialized pointer read (UNINIT) (happens in
the last ExFreePoolWithTag(basicInfo, TAG_IO) call when the
"(!NT_SUCCESS(status) || ServiceName != NULL)" case is not taken).
- Centralize all the ExFreePoolWithTag(basicInfo, TAG_IO) cleanups
at the end of the function.
- Both cases "(driverName.Buffer == NULL)" and "(ServiceName != NULL)"
can only be taken when basicInfo != NULL, so assert on this fact.
- Fix/add comments;
- Reduce indentation level;
- Direct copy for registry integer values;
- Use for-loops for linked lists;
- Use ULONG when the API uses it (sizes for Ob, or REG_DWORD data in registry).

The logging is helpful to alert us when we should really
recalculate the base addresses for performance reasons.
Spams a bit sometimes, sure, but it's worth it!
When freeing pages, free page entries with pages num == 3 were
incorrectly treated as entries with pages num >= 4 and thus
their re-insertion was not triggered. That lead to non paged pool
fragmentation (can be triggered by kmtest:ExPools, for example)
Also, altered the index acquisition code for MmNonPagedPoolFreeList
entries so it looks more clear
MSI on 2k3sp2 hides empty CD-ROM, and hides CD-ROM with iso mounted.
MSI on 2k3sp2 hides VBox shares, both: writable and read-only-ones.
MSI on 2k3sp2 hides floppy drives with a floppy img mounted.
MSI on XPSP3 hides a mounted writable USB stick.

- Manage the lifetime of the temporary 'PartitionBuffer' buffer where
it is locally used only, and free it as soon as possible, just after
calculating the sector checksum. No need to then free it outside of
the main for-loop.
- When the 'DriveLayout' buffer is freed, ensure the pointer is NULL-ed
(and assert this at the top of the main for-loop), since it can also
be freed at cleanup outside this for-loop, and in this case a NULL
check is performed.
This will avoid the scenario of possibly double-freeing a pointer,
in the case the 'DriveLayout' was previously freed (when e.g. reading
the sector for checksum calculation failed), then the for-loop goes to
the next disk and stops early.
The purpose of 'SingleDisk' is the same as in the IopCreateArcNames()
function. It is an optimization for that when looking up the
firmware-recognized ARC disks list, in order to match one of these with
the current NT disk being analysed (see e.g. also in IopCreateArcNamesDisk()),
we avoid a possible IopVerifyDiskSignature() call and directly build a
corresponding ARC name NT symbolic link for it.
'SingleDisk' will actually be TRUE, whether the DiskSignatureListHead
list is empty or contains only one element: Indeed in only both these
cases, 'DiskSignatureListHead.Flink->Flink' will refer to the list head.
(If the list is empty but 'SingleDisk' is TRUE, this does not matter,
because the DiskSignatureListHead looking-up loop never starts.)
