2021-01-18nat: deal with flows instead of sessionsKlement Sekera1-5/+111
This change introduces flow concept to endpoint-dependent NAT. Instead of having a session and a plethora of special cases in code for e.g. hairpinning, twice-nat and others, figure all this out and store it in flow logic. Every flow has a match and a rewrite part. This unifies all the NAT packet processing cases into one - match a flow and rewrite the packet based on that flow. It also provides a cure for hairpinning dilemma where one part of the flow is on one worker and another on a different one. These cases are also sped up by not requiring destination adress lookup every single time to be able to rewrite source nat as this is now part of flow rewrite logic.

2020-08-17nat: sessions get expired when fib table removedFilip Varga1-0/+111
fib table removal would leave lingering sessions in vpp this patch is aimed at solving this issue by grouping sessions by source and destionation fib. if one of the fibs gets removed this grouping is tagged as expired and session won't be passed to non existing fib table Ticket: VPPSUPP-93 Type: improvement Change-Id: I45b1205a8b58d91f174e6feb862554ec2f6cffad Signed-off-by: Filip Varga <fivarga@cisco.com>
2020-05-13nat: fix LRU blocked by inactive sessionKlement Sekera1-0/+144
This fixes a situation where long-lived inactive session blocks LRU list. Solution is to have multiple LRU lists based on session type. This helps because session timeout is same for all sessions of same type. Type: fix Signed-off-by: Klement Sekera <ksekera@cisco.com> Change-Id: I5e54b2aab73b23911d6518d42e8c3f166c69a38c
