From 1c7104514cd40d2377caca36cf40c13b791bc5aa Mon Sep 17 00:00:00 2001 From: Florin Coras Date: Tue, 17 Oct 2017 00:03:13 -0700 Subject: session: rules tables This introduces 5-tuple lookup tables that may be used to implement custom session layer actions at connection establishment time (session layer perspective). The rules table build mask-match-action lookup trees that for a given 5-tuple key return the action for the first longest match. If rules overlap, ordering is established by tuple longest match with the following descending priority: remote ip, local ip, remote port, local port. At this time, the only match action supported is to forward packets to the application identified by the action.
