CreateFile创建文件设备蓝屏

用户模式下的代码
    CHAR DriverName[256];
    CHAR DeviceName[] = "HideFileService";
    CHAR DevicePath[] = "\\\\.\\SFilter";

    HANDLE hDevice = CreateFile(DevicePath,GENERIC_READ | GENERIC_WRITE,0,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);
    if (INVALID_HANDLE_VALUE == hDevice)
    {
        printf("%s Device Failed Error Code:[%08x]\n", DevicePath, GetLastError());
    }
    else
    {
        CloseHandle(hDevice);
    }

为什么我一运行就蓝屏啊！！！

You have a buggy driver. Check CREATE IRP routines.

NTSTATUS
FsDeviceCreate(IN PDEVICE_OBJECT DeviceObject,
               IN PIRP Irp)
{
    if (g_CDO == DeviceObject)
    {
        KdPrint(("CDO Created!\n"));
        Irp->IoStatus.Information = 0;
        Irp->IoStatus.Status = STATUS_SUCCESS;
        IoCompleteRequest(Irp, IO_NO_INCREMENT);
        __asm int 3;
        return STATUS_SUCCESS;
    }
    KdPrint(("HOOK IRP_CREATE\n"));
    return SfPassThrough(DeviceObject, Irp);
}
SoftICE提示成功的执行到了__asm int 3;
但是还是错误啊，michaelgz，你帮我看看吧

呵呵 SoftICE发现了bug
NTSTATUS
SfPassThrough(IN PDEVICE_OBJECT DeviceObject, IN PIRP Irp)
{
    PIO_STACK_LOCATION irpSp = IoGetCurrentIrpStackLocation(Irp);
    //不处理
    //ASSERT(IS_MY_DEVICE_OBJECT(DeviceObject));
    if (g_CDO == DeviceObject)
    {
        KdPrint((("ERROR CDO:[%08x]\n"), irpSp->MajorFunction, irpSp->MinorFunction));
        _asm int 3;

        Irp->IoStatus.Status = STATUS_INVALID_DEVICE_REQUEST;
        Irp->IoStatus.Information = 0;
        IoCompleteRequest(Irp, IO_NO_INCREMENT);
        return STATUS_INVALID_DEVICE_REQUEST;
    }
    IoSkipCurrentIrpStackLocation(Irp);
    return IoCallDriver(((PDEVICE_EXTENSION)DeviceObject->DeviceExtension)->AttachedToDevice, Irp);
}

ICE中断显示Error CDO [00000012]
查00000012得到：IRP_MJ_CLEANUP,原来是我没有设置IRP_MJ_CLEANUP的处理函数
导致直接使用SfPassThrough，而CDO没有AttachedToDevice，导致蓝屏

郁闷啊 不是有IRP_MJ_CLOSE了吗
MS还发一个IRP_MJ_CLEANUP给我干什么啊，害我从昨天下午郁闷到现在，还好我从小就养成了良好的调试习惯，哈哈
