2021-09-09linux-cp: Complete interface creation logicPim van Pelt1-3/+3
Linux Control Plane interface creation logic is currently only able to create untagged interfaces, and dot1q VLAN sub-interfaces. This change makes it possible to create dot1ad VLAN sub-ints, and Q-in-AD as well as Q-in-Q sub-interfaces as well. It makes the plugin a bit more robust by catching a few common errors, such as creating an lcp on a sub-interface without its parent having one, and creating an lcp on a sub-interface that is not exact-match. This change has a bunch of smaller improvemnets as well. I documented my work in this post: https://ipng.ch/s/articles/2021/08/12/vpp-1.html It shows that after the change is merged, all VPP interface types now create and operate cleanly as LCP interfaces as well.

2021-06-24linux-cp: stop managing adjacencies for tunnelsAlexander Chernavin1-0/+12
Type: fix Outbound packets which arrive on tun/L3 interfaces use a default adjacency for the interface & address family from the corresponding interface pair. However, there are entries in the linux-cp adj table that are created for them. Managing these entries might cause a segfault because the rewrite data might exceed the reserved space for it of 28 bytes in the linux-cp adj key (e.g. in case of GRE IPv6). With this change, stop creating adjacencies for tun/L3 interfaces in the linux-cp adj table and delegating them.

2021-05-21linux-cp: Add delegate to adjacenciesMatthew Smith1-10/+74
Type: improvement When an adjacency is created, add the linux-cp delegate on the new adjacency so we can later deal with modifications & deletions in our cache of adjacency data. Add a pool of hash keys and associate the pool index for a particular key with the adj_delegate_t. If the rewrite on an adjacency is changed, this will allow us to delete the old hash table entry and it will not become orphaned.
