Fix TCP FRTO logic so that it always notices when snd_una advances, indicating that any RTO after that point will be a new and distinct loss episode. Previously there was a very specific sequence that could cause FRTO to fail to notice a new loss episode had started: (1) RTO timer fires, enter FRTO and retransmit packet 1 in write queue (2) receiver ACKs packet 1 (3) FRTO sends 2 more packets (4) RTO timer fires again (should start a new loss episode) The problem was in step (3) above, where tcp_process_loss() returned early (in the spot marked "Step 2.b"), so that it never got to the logic to clear icsk_retransmits. Thus icsk_retransmits stayed non-zero. Thus in step (4) tcp_enter_loss() would see the non-zero icsk_retransmits, decide that this RTO is not a new episode, and decide not to cut ssthresh and remember the current cwnd and ssthresh for undo. There were two main consequences to the bug that we have observed. First, ssthresh was not decreased in step (4). Second, when there was a series of such FRTO (1-4) sequences that happened to be followed by an FRTO undo, we would restore the cwnd and ssthresh from before the entire series started (instead of the cwnd and ssthresh from before the most recent RTO). This could result in cwnd and ssthresh being restored to values much bigger than the proper values.

由 Hannes Frederic Sowa 提交于
tcp_tw_recycle heavily relies on tcp timestamps to build a per-host ordering of incoming connections and teardowns without the need to hold state on a specific quadruple for TCP_TIMEWAIT_LEN, but only for the last measured RTO. To do so, we keep the last seen timestamp in a per-host indexed data structure and verify if the incoming timestamp in a connection request is strictly greater than the saved one during last connection teardown. Thus we can verify later on that no old data packets will be accepted by the new connection. During moving a socket to time-wait state we already verify if timestamps where seen on a connection. Only if that was the case we let the time-wait socket expire after the RTO, otherwise normal TCP_TIMEWAIT_LEN will be used. But we don't verify this on incoming SYN packets. If a connection teardown was less than TCP_PAWS_MSL seconds in the past we cannot guarantee to not accept data packets from an old connection if no timestamps are present. We should drop this SYN packet. This patch closes this loophole. Please note, this patch does not make tcp_tw_recycle in any way more usable but only adds another safety check: Sporadic drops of SYN packets because of reordering in the network or in the socket backlog queues can happen. Users behing NAT trying to connect to a tcp_tw_recycle enabled server can get caught in blackholes and their connection requests may regullary get dropped because hosts behind an address translator don't have synchronized tcp timestamp clocks. tcp_tw_recycle cannot work if peers don't have tcp timestamps enabled. In general, use of tcp_tw_recycle is disadvised.

As of 4fddbf5d ("sit: strictly restrict incoming traffic to tunnel link device"), when looking up a tunnel, tunnel's underlying interface (t->parms.link) is verified to match incoming traffic's ingress device. However the comparison was incorrectly based on skb->dev->iflink. Instead, dev->ifindex should be used, which correctly represents the interface from which the IP stack hands the ipip6 packets. This allows setting up sit tunnels bound to vlan interfaces (otherwise incoming ipip6 traffic on the vlan interface was dropped due to ipip6_tunnel_lookup match failure).

xgene_enet_get_ring_size() returns a negative value in case of an error, but its only caller in xgene_enet_create_desc_ring() currently uses the return value directly as u32. Instead, check for a negative value first and error out in case. Also move the call to xgene_enet_get_ring_size() before devm_kzalloc() so we don't need to free anything in the error path.
