For the cases where a lot of interfaces are used in conjunction with a lot of LLC sockets bound to the same SAP, the iteration of the socket list becomes prohibitively expensive. Replacing the list with a a local address based hash significantly improves the bind and listener lookup operations as well as the datagram delivery. Connected sockets delivery is also improved, but this patch does not address the case where we have lots of sockets with the same local address connected to different remote addresses. In order to keep the socket sanity checks alive and fast a socket counter was added to the SAP structure. Signed-off-by: NOctavian Purdila <opurdila@ixiacom.com> Signed-off-by: NDavid S.

For the reclamation phase we use the SLAB_DESTROY_BY_RCU mechanism, which require some extra checks in the lookup code: a) If the current socket was released, reallocated & inserted in another list it will short circuit the iteration for the current list, thus we need to restart the lookup. b) If the current socket was released, reallocated & inserted in the same list we just need to recheck it matches the look-up criteria and if not we can skip to the next element. In this case there is no need to restart the lookup, since sockets are inserted at the start of the list and the worst that will happen is that we will iterate throught some of the list elements more then once. Note that the /proc and multicast delivery was not yet converted to RCU, it still uses spinlocks for protection. Signed-off-by: NOctavian Purdila <opurdila@ixiacom.com> Signed-off-by: NDavid S.

During dev->open(), make sure we get at least one skb on the Rx ring. Otherwise abort the interface load.

Fix dev->stop shutdown bug where driver was stopping xmit queue and then disabling intrs. Fix is to disable intrs first and then stop the xmit queue, otherwise an interrupt could cause the queue to be rewoken. Also, no need to explicitly do queue servicing because queues are cleaned and reset back to initial state at end of dev->stop. Servicing queues also had the side-effect of also rewakening the xmit queue, which is not what we want.

Add rtnetlink init_rcvwnd to set the TCP initial receive window size advertised by passive and active TCP connections. The current Linux TCP implementation limits the advertised TCP initial receive window to the one prescribed by slow start. For short lived TCP connections used for transaction type of traffic (i.e. http requests), bounding the advertised TCP initial receive window results in increased latency to complete the transaction. Support for setting initial congestion window is already supported using rtnetlink init_cwnd, but the feature is useless without the ability to set a larger TCP initial receive window. The rtnetlink init_rcvwnd allows increasing the TCP initial receive window, allowing TCP connection to advertise larger TCP receive window than the ones bounded by slow start.

Slightly optimize tcp_sendmsg since NETIF_F_SG is used many times iteratively in the loop. The only other modification is to change: } else if (i == MAX_SKB_FRAGS || (!i && !(sk->sk_route_caps & NETIF_F_SG))) { to: } else if (i == MAX_SKB_FRAGS || !sg) { The reason why this change is correct: this code (other than the MAX_SKB_FRAGS case) executes only due to the else part of: "if (skb_tailroom(skb) > 0) {" - i.e. there was no space in the skb to put the data inline. Hence SG is false is a sufficient condition, and there is no way a fragment can be added to the skb.

tcp_push checks tcp_send_head and calls __tcp_push_pending_frames, which again checks tcp_send_head, and this unnecessary check is done for every other caller of __tcp_push_pending_frames.
