The IPIP and IP6IP6 tunnel tests call check_counters() to verify flowtable offloading occurred, but the flow-add rule only matches meta oif "veth1". When traffic is routed through a tunnel device, oif is the tunnel interface (tun0, tun6, etc.), not veth1, so the flow-add rule never fires, no flowtable entry is created, and counters stay at zero — producing a silent false pass. Fix by adding tunnel-specific flow-add rules for each tunnel interface. These match TCP dport 12345 traffic before the bare accept rule, set ct mark, add the flow to the flowtable, and increment routed_orig. The existing routed_repl rule on veth0 already handles the reply direction since decapsulated reply packets exit through the physical interface. Also add check_counters() for the IP6IP6 non-VLAN and IP6IP6-over-VLAN tests which previously used a bare PASS message. Fixes: |
