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.

I'm trying to pass outgoing NBL from a NDIS filter driver to a user mode program (via IRP using METHOD_IN_DIRECT ). I realized that I can only pass 1 MDL at once. But an NBL chain(NetBufferLists) consists of 1 or more NBLs, each NBL in the chain consists of 1 or more NBs, and each NB consists of 1 or more MDLs. How can I send them all using 1 IRP. If I need to go through all the MDLs separately, then how can I collect all these MDLs into an NBL chain in the receive path, as it was in the original NBL.
Maybe I need to encapsulate all NetBufferLists in 1MDL. Then how to do it.
