Package: iproute2 Version: 4.9.0-1+deb9u1 Severity: normal Tags: ipv6
I stepped on a bug that is triggered when enabling ipv6 forwarding. Whenever I request the route for my subnet, with ipv6 forwarding enabled, it responds with the looopback. For example a server with IPv6 1234:1234:1:2::40/64 on eth0. When I run the commands: `ip route get 1234:1234:1:2::/64` `ip route get 1234:1234:1:2::0` I get the route with the right interface: ``` # sysctl net.ipv6.conf.all.forwarding net.ipv6.conf.all.forwarding = 0 # ip route get 1234:1234:1:2::/64 1234:1234:1:2:: from :: dev eth0 proto kernel src 1234:1234:1:2::40 metric 256 pref medium ``` But as soon as I enable forwarding it returns a bad value: ``` # sysctl net.ipv6.conf.all.forwarding=1 net.ipv6.conf.all.forwarding = 1 # ip route get 1234:1234:1:2::/64 local 1234:1234:1:2:: from :: dev lo table local proto none src 1234:1234:1:2::40 metric 0 pref medium ``` I can "cheat" around, for example by requesting the route for 1234:1234:1:2::1/64 it will return the expected route.
