G'day. I posted this earlier today to freebsd-net and now that I have read more, I guess I should have posted it here first. Apologies to those on both mail lists. Can anyone explain the relationship between BPF and netgraph sockets? I am trying to intercept packets destined for a process which is using BPF for read and write operations on an interface (and drop not-so-good packets). I can see all packets on the interface (using NgRecvData), however I am unable to drop the bad packets (by not calling my NgSendData function) as the process using BPF seems to be bypassing the netgraph functions.
