[Bro-Dev] [JIRA] (BIT-1363) Clustered AF_PACKET support

[Michal Purzynski (JIRA)]

    [ https://bro-tracker.atlassian.net/browse/BIT-1363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=22005#comment-22005 ] 

Michal Purzynski commented on BIT-1363:
---------------------------------------

./networking/packet_mmap.txt

  - PACKET_FANOUT_HASH: schedule to socket by skb's packet hash

(the only one that's symmetric)

I've also tested it on netsniff-ng and similar and got both directions in a single process, each time.

The code that got merged into Bro recently, about af_packet, lacks TPACKET_V3 support, but that's another thing (a huge performance optimization).

> 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.
