Summary

"route add <host> -iface <netif>" for a netif without an IPv4/IPv6 address
fails with EINVAL. Need to use a link-level ifaddr for gw if an ifaddr
for dst is not found as the rtsock-based implementation does.

Test Plan

ifconfig tun0 create
ifconfig tun0 up
route add 192.0.2.1 -iface tun0

This looks good to me.

I have a separate patch that introduces v4 and v6 atf-sh test cases for sbin/route that I will land along with D41436 when it gets a v6 test case soon.

This revision is now accepted and ready to land.Nov 28 2023, 6:00 PM
