I wanted to post the latest state of the conntrack & nat patches based on Justin's initial RFC before I travel.
Changes to Justin's patch include the introduction of a new model to convert nested Netlink attributes to a in-kernel only struct to allow the zone support patch to keep a reference to struct nf_conn and register it as template in the conntracker. The use of nested attributes will allow to specify conntrack helpers and additional conntrack expectations later on. That patch still requires a change to accurately calculate the sf_acts Netlink message size to avoid realloc during message construction. The nat patch is still very WIP. The configuration of the nat action in the data path works but I haven't worked much further. Justin Pettit (1): RFC: Add support for connection tracking.
