FileSpy中添加IRP_MJ_DEVICE_CONTROL无效果

FileSpy中添加DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL] = SpyDeviceControl;

NTSTATUS
SpyDeviceControl( IN PDEVICE_OBJECT DeviceObject, IN PIRP Irp )
{
NTSTATUS status = STATUS_NOT_IMPLEMENTED;
PIO_STACK_LOCATION irpSp = IoGetCurrentIrpStackLocation(Irp);
ULONG ControlCode;
PVOID lpInBuf = NULL;

if (DeviceObject == gControlDeviceObject)
{
ControlCode = irpSp->Parameters.DeviceIoControl.IoControlCode;
lpInBuf = irpSp->Parameters.DeviceIoControl.Type3InputBuffer;
lpInBuf = Irp->AssociatedIrp.SystemBuffer;
KdPrint(("Control Code:[%08x]\n", ControlCode));
switch (ControlCode)
{
case ADD_FILE:
Addnode(lpInBuf);
break;
case ADD_PROC:
Addnodeproc(lpInBuf);
break;
case KAI_FANG:
kaifang=TRUE;
break;
case NO_KAIFANG:
kaifang=FALSE;
break;
}
Irp->IoStatus.Status = STATUS_SUCCESS;
IoCompleteRequest(Irp, IO_NO_INCREMENT);
return Irp->IoStatus.Status;
}
else
{
return SpyPassThrough( DeviceObject, Irp );
}
}
driverentry中初始化了几个变量 别的地方未改动，

deviceiocontrol时createfile能成功，但deviceiocontrol后getlasterror错误号87 参数错误
还是用这个win32程序向以前的驱动发deviceiocontrol就可以 大牛们救救我吧 弄了两天了 难道是FileSpy中有秘密吗

补充一下，同样的代码 放到sfilte里面就可以 deviceiocontrol能正常使用

FileSpy has FastIoDeviceControl routine SpyFastIoDeviceControl() which supersedes your MJ_DEVICE_CONTROL.
