2018-04-12Handle DHCP replies with NAT44 forwarding enabledMatthew Smith1-48/+57
When NAT44 forwarding is disabled, if a DHCP server-to- client packet arrives on an outside interface, it is handled correctly by setting the next node to the next feature on the ip4-unicast feature arc, where it can be processed. When NAT44 forwarding is enabled, if a DHCP server-to- client packet arrives, it is not handled any differently than other packets and ends up going to ip4-lookup which results in the packet being dropped. Move the check for DHCP server-to-client packets outside of the block that is executed if forwarding is disabled so DHCP replies will be processed in either case.

2018-03-30acl-plugin: implement an optional session reclassification when ACL is ↵Andrew Yourtchenko4-10/+128
(re-)applied There were several discussions in which users would expect the sessions to be deleted if the new policy after the change does not permit them. There is no right or wrong answer to this question - it is a policy decision. This patch implements an idea to approach this. It uses a per-interface-per-direction counter to designate a "policy epoch" - a period of unchanging rulesets. The moment one removes or adds an ACL applied to an interface, this counter increments. The newly created connections inherit the current policy epoch in a given direction. Likewise, this counter increments if anyone updates an ACL applied to an interface. There is also a new (so far hidden) CLI "set acl-plugin reclassify-sessions [0|1]" (with default being 0) which allows to enable the checking of the existing sessions against the current policy epoch in a given direction. The session is not verified unless there is traffic hitting that session *in the direction of the policy creation* - if the epoch has changed, the session is deleted and within the same processing cycle is evaluated against the ACL rule base and recreated - thus, it should allow traffic-driven session state refresh without affecting the connectivity for the existing sessions. If the packet is coming in the direction opposite to which the session was initially created, the state adjustment is never done, because doing so generically is not really possible without diving too deep into the special cases, which may or may not work.

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.

In version 2 slave is always producer, and in case of master-to-slave rings, slave is responsible for populating ring with empty buffers. As this is major change, we need to bump version number. In addition, descriptor size is reduced to 16 bytes. This change allows zero-copy-slave operation (to be privided in the separate patch).

2018-03-21bond: Add bonding driver and LACP protocolSteven24-0/+3994
Add bonding driver to support creation of bond interface which composes of multiple slave interfaces. The slave interfaces could be physical interfaces, or just any virtual interfaces. For example, memif interfaces. The syntax to create a bond interface is create bond mode <lacp | xor | acitve-backup | broadcast | round-robin> To enslave an interface to the bond interface, enslave interface TenGigabitEthernet6/0/0 to BondEthernet0 Please see src/plugins/lacp/lacp_doc.md for more examples and additional options. LACP is a control plane protocol which manages and monitors the status of the slave interfaces. The protocol is part of 802.3ad standard. This patch implements LACPv1. LACPv2 is not supported. To enable LACP on the bond interface, specify "mode lacp" when the bond interface is created. The syntax to enslave a slave interface is the same as other bonding modes.
