I have been trying to swallow the profusion of bpf related materials for a bit now, and decided to punt and merely ask the questions.
A) Is it possible to attach a filter to a netlink socket (RTM_NEWROUTE and RTM_DELROUTE primarily) (examples?) B) If so, can I filter on the route proto field? (easily?) The moral equivalent is: ip route show proto ra which in the case where I have a (um, very) large bgp (or babel) table would ideally filter things down to the 16 ra routes. Similar filtering might include RTA_DST, or RTA_TABLE, etc. ... BSD has RTF_PROTO2, but NLM_F_MATCH for linux never landed. ... I have a couple other things on my mind for improving flent.org's statistics gathering in general, but that's my starting point. -- Dave Täht Let's go make home routers and wifi faster!
