The free OSR Learning Library has more than 50 articles on a wide variety of topics about writing and debugging device drivers and Minifilters. From introductory level to advanced. All the articles have been recently reviewed and updated, and are written using the clear and definitive style you've come to expect from OSR over the years.

IS this code pattern correct?
KeInitializeSemaphore(pSem, 0, 1);
KeInitializeDpc(pDpc, func, pBuffer);
KeInsertQueueDpc(pDpc, pSem, NULL);
KeWaitForSingleObject(pSem, Executive, KernelMode, FALSE, NULL);
This will wait the thread infinitely for the semaphore (which is being set inside the DPC callback 'func', even though the DPCs should fire away almost immediately, what happens if a Unload Request comes to the driver in between?
Will it block on this thread? or will it unload the image without cancelling the DPC potentially causing a BSOD later when the DPC fires on a dangling pointer?
