It is ip_rcv_finish() called from ip_rcv():
if (skb->dst == NULL) {
int err = ip_route_input(skb, iph->daddr, iph->saddr, iph->tos,
skb->dev);
if (unlikely(err)) {
if (err == -EHOSTUNREACH)
IP_INC_STATS_BH(IPSTATS_MIB_INADDRERRORS);
else if (err == -ENETUNREACH)
IP_INC_STATS_BH(IPSTATS_MIB_INNOROUTES);
goto drop;
}
}
So you will have to specify device, you got your skb via.
Actually it is not exactly needed in some cases, you will need interface
index (dev->ifindex). You can find socket by using that number instead
of dereferencing dst.
