It's the same problem that previous fix about blackhole and prohibit routes. When adding a throw route, it was handled like a classic route. Moreover, it was only possible to add this kind of routes by specifying an interface. Before the patch: $ ip route add throw 2001::2/128 RTNETLINK answers: No such device $ ip route add throw 2001::2/128 dev eth0 $ ip -6 route | grep 2001::2 2001::2 dev eth0 metric 1024 After: $ ip route add throw 2001::2/128 $ ip -6 route | grep 2001::2 throw 2001::2 dev lo metric 1024 error -11 Reported-by: Markus Stenberg <markus.stenberg@iki.fi> Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
