2021-11-19fib: Don't use [midchain] adjacencies to change an interface's feature arcNeale Ranns2-4/+8
Type: fix Using the adjacency to modify the interface's feature arc doesn't work, since there are potentially more than one adj per-interface. Instead have the interface, when it is created, register what the end node of the feature arc is. This end node is then also used as the interface's tx node (i.e. it is used as the adjacency's next-node). rename adj-midhcain-tx as 'tunnel-output', that's a bit more intuitive. There's also a fix in config string handling to: 1- prevent false sharing of strings when the end node of the arc is different. 2- call registered listeners when the end node is changed For IPSec the consequences are that one cannot provide per-adjacency behaviour using different end-nodes - this was previously done for the no-SA and an SA with no protection. These cases are no handled in the esp-encrypt node. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: If3a83d03a3000f28820d9a9cb4101d244803d084

2021-07-28gre: set proper fib index for unnumbered interfaces, unset fib index before ↵Stanislav Zaikin1-0/+5
forwarding gre payload This commit introduces 2 fixes: 1) After GRE decapsulation sw_if_index[VLIB_TX] is set as fib index of GRE tunnel. But since GRE tunnel can work on v4 endpoints and have v6 payload, we need to reset it. In case we get IPv6 packet inside IPv4 GRE tunnel (or vice-versa) fib index can be (and usually is) invalid. 2) Check that ip-table and ip6-table are the same when setting interface as an unnumbered one. Also, fix for the pipe test include setting the right unnumbered interface for the pipes Type: fix Signed-off-by: Stanislav Zaikin <zstaseg@gmail.com> Change-Id: Id13d239cfdd21e0db6b1c9725f01c40d4af4d800
2021-05-20gre: Walk IPv6 adjacencies during restackMatthew Smith1-2/+4
Type: fix If a GRE tunnel is created and the peer is not resolved yet and an IPv6 route is added which points to the tunnel, packets matching the route will be dropped. When the tunnel peer is resolved, adjacencies on the tunnel interface should be restacked and packets matching the route can be encapsulated and sent.. There is a loop that is intended to do this for both IPv4 and IPv6. The call to walk adjacencies is invoked in a "return" statement though. So the loop is exited and the function returns before IPv6 adjacencies are walked. Remove the return so the loop finishes.

Type: fix - the CLI was broken when a nh-table-id was present, since it overwrote the next-hop address - bouncing interface state stacked the adjacencies on the tunnel's destination (which is all zeros) - don't crash in the switch path if the interface has no hw-address Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I1ba9fdc9b2185899b753a2d40f23afa847a3ef4f
2021-02-15ip: Path MTUNeale Ranns1-2/+7
Type: feature Support setting the MTU for a peer on an interface. The minimum value of the path and interface MTU is used at forwarding time. the path MTU is specified for a given peer, by address and table-ID. In the forwarding plane the MTU is enfored either: 1 - if the peer is attached, then the MTU is set on the peer's adjacency 2 - if the peer is not attached, it is remote, then a DPO is added to the peer's FIB entry to perform the necessary fragmentation.
