Michal Purzynski commented on BIT-1363: --------------------------------------- I'm trying to understand now how Bro uses the libpcap and I'm reading the libpcap source at the same time. PcapSource::OpenLive() calls pcap_create() and pcap_activate() later, which in turn, inside libpcap calls pcap_activate_linux() that tries hard to use mmap() and TPACKET_V3. Cool :-) A lot of magic happens after but libpcap is really good in autodetection - granted that you use it like designed, and not pick and choose functions. So we are good here. A documentation piece would be nice, that would recommend kernel at least 3.13 and libpcap 1.6 (or even 1.5). Maybe it will work on RHEL 7 stone-age-old 3.10. > 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. -- This message was sent by Atlassian JIRA (v7.0.0-OD-04-018#70102) _______________________________________________ bro-dev mailing list bro-dev@bro.org http://mailman.icsi.berkeley.edu/mailman/listinfo/bro-dev
