net: ipv6: Add RT6_LOOKUP_F_IFACE flag if oif is set
Wolfgang reported that IPv6 stack is ignoring oif in output route lookups: With ipv6, ip -6 route get always returns the specific route. $ ip -6 r 2001:db8:e2::1 dev enp2s0 proto kernel metric 256 2001:db8:e2::/64 dev enp2s0 metric 1024 2001:db8:e3::1 dev enp3s0 proto kernel metric 256 2001:db8:e3::/64 dev enp3s0 metric 1024 fe80::/64 dev enp3s0 proto kernel metric 256 default via 2001:db8:e3::255 dev enp3s0 metric 1024 $ ip -6 r get 2001:db8:e2::100 2001:db8:e2::100 from :: dev enp2s0 src 2001:db8:e3::1 metric 0 cache $ ip -6 r get 2001:db8:e2::100 oif enp3s0 2001:db8:e2::100 from :: dev enp2s0 src 2001:db8:e3::1 metric 0 cache The stack does consider the oif but a mismatch in rt6_device_match is not considered fatal because RT6_LOOKUP_F_IFACE is not set in the flags.
