The BSD kernel does not support the onlink flag and BIRD does not use direct routes for next hop validation, instead depends on interface address ranges. We would like to handle PtMP cases with only host addresses configured, like: ifconfig wg0 192.168.0.10/32 route add 192.168.0.4 -iface wg0 route add 192.168.0.8 -iface wg0 To accept BIRD routes with onlink next-hop, like: route 192.168.42.0/24 via 192.168.0.4%wg0 onlink BIRD would dismiss the route when receiving from the kernel, as the next-hop 192.168.0.4 is not part of any interface subnet and onlink flag is not kept by the BSD kernel. The commit fixes this by assuming that for routes received from the kernel, any next-hop is onlink on ifaces with only host addresses. Thanks to Stefan Haller for the original patch. |
