Here is the step to reproduce it: modprobe sit ip link add sit1 type sit remote 10.16.0.121 local 10.16.0.249 ip l s sit1 up ip -6 a a dev sit1 2001:1234::123 remote 2001:1234::121 ping6 2001:1234::121 The problem is that ipv6_anycast_destination() uses unconditionally skb_dst(skb), which is NULL in this case. Not sure what is the best way to fix this, any suggestions?
