Tom Wilkie 277bd70491 Don't every store NEW conntrack flows (only every store updates). (#1541) 
This closes a small window where we might produce reports which contain flows that are NEW but have never seen an UPDATE, which can potentially be invalid.

Tom Wilkie 1a286eac04 Use an exec'd conntrack in 'events' mode instead of repeatedly execing it for NAT mappings. Also use conntrack to populate the endpoint table. 2015-08-27 16:29:33 +00:00
