Hi all. I have a file system legacy filter driver. I try to send messages to the driver from user mode it works fine. When I try to send new messages(not existing in the driver) from my user-mode application I face BSOD issues. Thanks in advance. Can you please prove a solution?
I have shared the sample code below.
NTSTATUS cwDevIoControl(PDEVICE_OBJECT DeviceObject, PIRP Irp)
status = STATUS_SUCCESS;
ioStack = IoGetCurrentIrpStackLocation(Irp);
inBuf = Irp->AssociatedIrp.SystemBuffer;
outBuf = Irp->AssociatedIrp.SystemBuffer;
lControlCode = ioStack->Parameters.DeviceIoControl.IoControlCode;
Irp->IoStatus.Information = 0;// Set the status field to zero for completion
IoSkipCurrentIrpStackLocation( Irp );// this is where bsod happens
return IoCallDriver( , Irp );
Irp->IoStatus.Status = status;
