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.

2021-06-24linux-cp: add callbacks for pair managementMatthew Smith2-15/+41
Type: improvement Allow callbacks to be registered which will be called when an interface pair is added or deleted. Change-Id: I1c413ac2ada802021f9e56e2f878ce67e5eda2f5 Signed-off-by: Matthew Smith <mgsmith@netgate.com>
2021-06-03linux-cp: use default adjacencyMatthew Smith1-21/+16
Type: fix Outbound packets from the host have an adjacency lookup performed so buffer metadata can be filled in and output features can be applied. If no adjacency is found for a packet, it gets dropped. This breaks DHCP and possibly other things since the DHCP reply to a discover request is sent to a destination MAC address that is determined by the contents of the request packet rather than any existing neighbor table entry. If adjacency lookup for outbound packets does not find an entry, use the default adjacency for the interface & address family.

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.

2021-02-17linux-cp: fix coverity defectMatthew Smith1-0/+6
Type: fix If no host interface name is passed to the CLI command which creates an interface pair, NULL gets passed to lcp_itf_pair_create() and a seg fault occurs. Check whether a host interface name was provided and fail gracefully if none was given. Change-Id: I82886f4c2ee710e206c751c34a74399112e9062c Signed-off-by: Matthew Smith <mgsmith@netgate.com>
