![]() Currently we always use the first member of the arp_queue to determine the sender ip address of the arp packet (or in case of IPv6 - source address of the ndisc packet). This skb is fixed as long as the queue is not drained by a complete purge because of a timeout or by a successful response. If the first packet enqueued on the arp_queue is from a local application with a manually set source address and the to be discovered system does some kind of uRPF checks on the source address in the arp packet the resolving process hangs until a timeout and restarts. This hurts communication with the participating network node. This could be mitigated a bit if we use the latest enqueued skb's source address for the resolving process, which is not as static as the arp_queue's head. This change of the source address could result in better recovery of a failed solicitation. Cc: "David S.
