node/neighbordiscovery: correctly update and delete node IPv6 addresses#44540
Conversation
The logic in (*nodeNeighborHandler).NodeUpdate and (*nodeNeighborHandler).NodeDelete treats the node IPv4 address retrieved using node.GetNodeIP(false) (where false means ipv6=false) as an IPv6 address. This will lead to the address not correctly compared and propagated to the forwardableIPManager. Correct this by retrieving the node IPv6 address consistently for the IPv6 paths. Also rename an incorrectly named local variable in (*nodeNeighborHandler).NodeAdd while at it. Fixes: ccb7bd1 ("pkg/node/neighbordiscovery: Add node handler for neighbor discovery") Signed-off-by: Tobias Klauser <tobias@cilium.io>
