When nl_vlxan::create_endpoint(rtnl_link *) is called, it has no br_link, it calls nl_vlxan::create_endpoint(rtnl_link *, rtnl_link *, nl_addr *) with a nullptr for the bridge interface. This causes it to not add the endpoint to the l2 overlay group, breaking connectivity. Since we only ever call nl_vlxan::create_endpoint(rtnl_link *) from places where we know a br_link exists, add it to the arguments. Should fix spurious failures of the vxlan-bridge tests in our testing pipelines. Fixes: ec8902a ("cnetlink::link_created(): call vxlan::create_endpoint() later") Signed-off-by: Jonas Gorski <[email protected]>
