Nicolas Dichtel 08b44656c0 gre: add link local route when local addr is any ... This bug was reported by Steinar H. Gunderson and was introduced by commit f7cb888633 ("sit/gre6: don't try to add the same route two times"). root@morgental:~# ip tunnel add foo mode gre remote 1.2.3.4 ttl 64 root@morgental:~# ip link set foo up mtu 1468 root@morgental:~# ip -6 route show dev foo fe80::/64 proto kernel metric 256 but after the above commit, no such route shows up. There is no link local route because dev->dev_addr is 0 (because local ipv4 address is 0), hence no link local address is configured. In this scenario, the link local address is added manually: 'ip -6 addr add fe80::1 dev foo' and because prefix is /128, no link local route is added by the kernel. Even if the right things to do is to add the link local address with a /64 prefix, we need to restore the previous behavior to avoid breaking userpace. Reported-by: Steinar H.
