I want to query information about FileObject, I receive during TDI_CONNECT.
I do the following :
IO_STATUS_BLOCK ioStatus;
KEVENT MyEvent;
…
KeInitializeEvent(&MyEvent,NotificationEvent,FALSE);
pMyIrp = TdiBuildInternalDeviceControlIrp(TDI_QUERY_INFORMATION,
pDevObj,
FileObject,
NULL,
NULL);
MyAddress = ExAllocatePoolWithTag(NonPagedPool, 1000, COMMON_TAG);
MyMdl = IoAllocateMdl(MyAddress,
500,
FALSE,
FALSE,
NULL);
TdiBuildQueryInformation(pMyIrp,
pDevObj,
FileObject,
NULL,
NULL,
TDI_QUERY_CONNECTION_INFO,
MyMdl);
pMyIrp->UserEvent = &MyEvent;
pMyIrp->UserIosb = &ioStatus;
Status = IoCallDriver(LowerDeviceObject , pMyIrp);
//--------------------------------------------------------------------------
the last line results in a Page Fault …
what am I doing wrong ?
help me please !!
Thanks in advance.
You are currently subscribed to ntdev as: $subst(‘Recip.EmailAddr’)
To unsubscribe send a blank email to leave-ntdev-$subst(‘Recip.MemberIDChar’)@lists.osr.com
Seems basically OK.
In my TDI sample code (which works):
1.) I use IoAllocateIrp instead of TdiBuildInternalDeviceControlIrp.
2.) I probe and lock the MDL pages. OTOH, that shouldn’t be necessary in
your case because you allocated from a non-paged pool.
Sorry I can’t be more helpful. The call does work…

To be more specific I can write, that the last 2 functions in stack are :
ntoskrnl!KiIpiServiceRoutine + 168F
ntoskrnl!KeSetEvent + 006F
I wonder, what could this mean ?
