DMF intercepts that call and dispatches it to each Module in the tree of instantiated Modules. Each Module handles each callback as it sees fit. Finally, DMF dispatches the callbacks to the client driver’s callbacks. If you want to reuse for example FIFO code in another driver. You need to understand the complex interaction between the units before extracting the code and the fields used to store the state. In this design, the driver maintains state in a device context and the code is divided into units that access the device context and communicate among themselves. As WDF calls into the driver, you are also responsible for dispatching work to each of the units as needed.

If you don’t have a handle, it doesn’t matter how great a kernel person you are. Later, we went over to analyzing the dispatch routine of IRP_MJ_DEVICE_CONTROL, followed by viewing how the IoManager treats users’ data. After that, we walked over a few bugs and how to find them and possibly exploit them. Creating devices is nice and all, but, of course, it isn’t enough for you to communicate with the driver. The driver receives IRPs, I/O Request Packets on behalf of the IoManager for specific triggers. For instance, if an application tries to open a handle to a device, the IoManager will invoke the relevant dispatch method assigned to the driver object.
