How to DO IRP_MJ_DEVICE_CONTROL in a minifilter

NTFSD
1

hi all,

I want to do IRP_MJ_DEVICE_CONTROL in my minifilter driver but I got bluescreen all the time.

My target is to call IOCTL_STORAGE_QUERY_RROPERTY in InstanceSetup to query infromation about the volume just attached.
Using following APIs
FltAllocateCallbackData
FltPerformAsynchronousIo
FltFreeCallbackData

Did anyone do this before?

I cound not find any example code that tell me how to use FltPerformAsynchronousIo properly.

And my first question is “Is it allowed to use IRP_MJ_DEVICE_CONTROL in a minifilter?”

Thank you for you reading and reply in advance.

I got improved.

Bluescreen was gone but I still got a error return in callbackData->IoStatus.Status

The error is 0xC0000010, STATUS_INVAILD_DEVICE_REQUEST

Some facts of my code, I implemented these in InstanceSetup callback routine:
Query.PropertyId = StorageDeviceProperty;
Query.QueryType = PropertyStandardQuery;

callbackData->Iopb->MajorFunction = IRP_MJ_INTERNAL_DEVICE_CONTROL;
callbackData->Iopb->TargetInstance = FltObjects->Instance;
callbackData->Iopb->Parameters.DeviceIoControl.Common.IoControlCode = IOCTL_STORAGE_QUERY_PROPERTY;
callbackData->Iopb->Parameters.DeviceIoControl.Buffered.SystemBuffer = (PVOID)&Query;
callbackData->Iopb->Parameters.DeviceIoControl.Common.InputBufferLength = sizeof(Query);

For me, STATUS_INVAILD_DEVICE_REQUEST points to no where, I don’t know what to do next.

If anyone had experience on this, please give me a hand.
Thank you.

Start over. Why do you need to send device control? What information are
you trying to get? Can you get what you need with FltGetVolumeProperties or
FltQueryVolumeInformation?

Thanks Ken.

I want to know the bus type (STORAGE_BUS_TYPE) of the instance/volume just attached.

FltGetVolumeProperties/FltQueryVolumeInformation don’t have this kind of information.
