2018-03-28NAT44: make 1:1NAT for DHCP addressed interface persistentMatus Fabian1-22/+53

2018-03-24User session counters stay <= per-user limitMatthew Smith3-17/+22
When a user session is allocated/reused, only increase one of the session counters for that user if the counters are below the per-user limit. THis addresses a SEGV that arises after the following sequence of events: - an outside interface IP address is put in a pool - a user exceeds the number of per-user translations by an amount greater than the number of per-user translations (nsessions + nstaticsessions > 100 + 100) - the outside interface IP address is deleted and then added again (observed when using DHCP client, likely happens if address changed via CLI, API also) - the user sends more packets that should be translated When nsessions is > the per-user limit, nat_session_alloc_or_recycle() reclaims the oldest existing user session. When an outside address is deleted, the corresponding user sessions are deleted. If the counters were far above the per-user limit, the deletions wouldn't result in the counters dropping back below the limit. So no session could be reclaimed -> SEGV.
