Injection

Question

I can't seem to find any clear documentation on which injection functions MUST run in a DPC/worker thread. http://msdn.microsoft.com/en-us/library/ff569975.aspx

Can anyone clarify this for me?

 

Answer 1

None of the have to run in a DPC/worker thread.

If you are doing injection at any of the transport layers (IN/OUTBOUND_TRANSPORT, STREAM_PACKET, etc.) and the protocol is TCP, then you need to use a worker thread at PASSIVE_LEVEL.  This is due to TCP's locking mechanisms.

Hope this helps,
