Bug ID: 44497
Summary: BattlEye 'BEDaisy' kernel service crashes on
unimplemented ntoskrnl.exe ObCallback (object manager)
functions
Product: Wine
Version: 3.1
Hardware: x86-64
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: ntoskrnl
Assignee: wine-bugs(a)winehq.org
Reporter: focht(a)gmx.net
Distribution: ---
Hello folks,
continuation of bug 44496
The kernel driver uses object manager callbacks in order to implement process
protection.
* ObRegisterCallbacks
* ObUnRegisterCallbacks
* ObGetFilterVersion
Example kernel driver code to show how the API is being used:
https://github.com/Microsoft/Windows-driver-samples/tree/master/general/obc…
--- quote ---
ObCallback Callback Registration Driver
The ObCallback sample driver demonstrates the use of registered callbacks for
process protection. The driver registers control callbacks which are called at
process creation.
Design and Operation
The sample exercises both the PsSetCreateProcessNotifyRoutineEx and the
ObRegisterCallbacks routines. The first example uses the ObRegisterCallbacks
routine and a callback to restrict requested access rights during a open
process action. The second example uses the PsSetCreateProcessNotifyRoutineEx
routine to reject a process creation by examining the command line.

BattlEye 'BEDaisy' needs semi-stubs. Pure stubs returning
'STATUS_NOT_IMPLEMENTED' is not enough. The driver init routine will fail.
* ObRegisterCallbacks -> return STATUS_SUCCESS (and fake handle)
* ObUnRegisterCallbacks -> just empty stub is enough
* ObGetFilterVersion -> return OB_FLT_REGISTRATION_VERSION
Also mentioned in tps://bugs.winehq.org/show_bug.cgi?id=41039#c0 ("Virtualbox
crashes with access violation, needs ntoskrnl.exe.FsRtlIsNameInExpression")
although not the problem there.

With these things fixed, the driver runs further - into next problems.

Hello folks,
removing broken (fileshare) download link.
There are multiple Internet Archive snapshots from the app author's website
"Clif Graves Consulting":

Unfortunately none of the linked app zip archives were ever captured on
archive.org
