microsoft virtual miniport adapter + vulnerability

When a miniport adapter is in the Initializing state and MiniportInitializeEx is successful, the miniport adapter enters the Paused state. When a miniport adapter is in the Pausing state and the pause operation is complete, the miniport adapter enters the Paused state. When a miniport adapter is in the Paused state, a miniport driver does not indicate received network data or accept send requests. If MiniportInitializeEx fails, the miniport adapter returns to the Halted state. If MiniportInitializeEx succeeds, the miniport adapter enters the Paused state. When a miniport adapter is in the Halted state and the NDIS calls the miniport driver's MiniportInitializeEx function, the miniport adapter enters the Initializing state. In the Initializing state, a miniport driver completes any operations that are required to initialize a miniport adapter. When the miniport adapter is in the Paused, Restarting, Running, or Pausing state and NDIS calls the miniport driver's MiniportShutdownEx function, the miniport adapter enters the Shutdown state. When the miniport adapter is in the Paused state and NDIS calls the MiniportHaltEx function, the miniport adapter returns to the Halted state.Ī miniport adapter in the Shutdown state cannot be used until the system is shut down and restarted. When a miniport adapter is in the Halted state, and NDIS calls the driver's MiniportInitializeEx function to initialize the miniport adapter, the miniport adapter enters the Initializing state. Halted Halted is the initial state of all miniport adapters. The following defines the adapter states: However, you should note that an overlying driver cannot complete a pause operation while its transmit packets are pending. For a reset operation, the driver can fail transmit request packets or it can keep them queued and complete them later. In this case, the driver can complete either the reset or the pause operation in any order while following the normal requirements for each operation. For example, NDIS might call a driver's pause handler when there is a reset operation in progress. Also, the state of the adapter might change while a reset operation is in progress. Note The reset operation does not affect miniport adapter operational states.

The following figure shows the interrelationships between these states. For each miniport adapter that it manages, an NDIS miniport driver must support the following set of operational states:
