DriverVerifier problem

NTFSD
1

Hi,

I am in the process of implementing a system that consist of two separate drivers one is a sFilter based FSFD and the other is an unloadable function driver that communicate with the FSFD. To be able to access the fixed FSFD the function driver ( through a specialized IOCTL ), discover the FSFD using ‘IoGetDeviceObjectPointer’. When running with the DriverVerifier I get the blue screen of death with IRQL_NOT_LESS_OR_EQUAL, Stop: 0x0000000A ( 0xE1A46D60, 0x00000001, 0x00000002, 0x804ECC50 ).

WinDbg with !analyze –v output:

What may be wrong with my code? What may cause such a problem? Why does it happen only with the DriverVerifier?

P.S.

DriverVerifier is set to verify the following properties:

Deadlock detection

Any help comment or sample would be appreciated.

Make sure that the ERESOURCE structure is located in non-paged pool.

Hi Lyndon,

Thanks for your immediate responce, well, Indeed this is the problem, disabling ‘Force IRQL checking’ for the DriverVerifier resolve the problem… does my driver be resistent to different IRQLs ?, the specific code segment in which this error occured always run in PASSIVE_LEVEL so it’s IRQL will never be 2 ( DISPATCH_LEVEL ), usage of the DriverVerifier caused intentionally for the IRQL to change…
Must I set the ‘Force IRQL checking’ to get my driver certified by microsoft?
What good does it make if it change the IRQL for methods that always run in a constant IRQL ( such as DriverEntry ) ???

Hi,

That’s not what Force IRQL checking does. What the option (essentially) does
is page out all pageable code, data and pool anytime your driver raises to
DISPATCH_LEVEL or above. The ERESOURCE package uses a spinlock internally
for synchronization, so my guess is that your ERESOURCE is in paged pool and
gets paged out when ExAcquireXxx grabs the spinlock. It’s either that or the
ERESOURCE has become hosed somehow.

Try !pool and !pte on 0xE1A46D60 and see what the debugger says.

Thanks for your response, I am allocating my resources using ExAllocatePoolWithTag( NonPagedPool, … ) shouldn’t this be enough to guarantee the resource will not be paged-out?
And what about the thread stack? cat it be paged-out? if so, is it possible to guarantee it will not be paged-out?
One last thing, how can I verify that my driver is not pageable?

Thanks again,
Naddav.

You are calling ExAcquireResourceExclusiveLite at DISPATCH_LEVEL, so when
the system forces out some of that routines code, you crash. This routine
can only be called at <= APC_LEVEL.

I recomend running this driver not only under verifier, but with CUV and the
checked build.
