Jianguo Wu e92ee025b5 ipvlan: Make skb->skb_iif track skb->dev for l3s mode ... [ Upstream commit 59a0b022aa ] For l3s mode, skb->dev is set to ipvlan interface in ipvlan_nf_input(): skb->dev = addr->master->dev but, skb->skb_iif remain unchanged, this will cause socket lookup failed if a target socket is bound to a interface, like the following example: ip link add ipvlan0 link eth0 type ipvlan mode l3s ip addr add dev ipvlan0 192.168.124.111/24 ip link set ipvlan0 up ping -c 1 -I ipvlan0 8.8.8.8 100% packet loss This is because there is no match sk in __raw_v4_lookup() as sk->sk_bound_dev_if != dif(skb->skb_iif). Fix this by make skb->skb_iif track skb->dev in ipvlan_nf_input().
