Seth Hall commented on BIT-1363:
Arg! I should have mentioned that I was working with kernel 3.10! Thanks guys. It's nice to have a definitive answer to that. I read all over the place today and couldn't find a coherent answer to that question. Now we're going to have other people randomly searching google for an answer to this question and getting directed to this ticket. :)
To reply to Michal's comment about TPACKET_V3, it looks like according to the libpcap changelog that TPACKET_V3 support was added to libpcap 1.5.0 (http://www.tcpdump.org/libpcap-changes.txt) so if you're running a more recent version than that you should already be using that.
> Clustered AF_PACKET support
> Key: BIT-1363
> URL: https://bro-tracker.atlassian.net/browse/BIT-1363
> Project: Bro Issue Tracker
> Issue Type: New Feature
> Components: Bro
> Affects Versions: git/master
> Reporter: Michal Purzynski
> Let's have a support for packet capture with the AF_PACKET sockets in multi worker configuration.
> Bro can use a single worker with af_packet, I have tested and it works, but having a direct support for multi-worker load balancing would allow to avoid the pf_ring for many deployments with the traffic level where DNA / ZC / Myricom / DAG is not required.
