Since .size is set properly in "struct pernet_operations l2tp_net_ops", allocating space for "struct l2tp_net" by hand is not correct, even causes memory leakage. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Sky2 status ring must be big enough to handle worst case number of status messages. It was being oversized (to handle dual port cards), and excessive number of tx ring entries were allowed. This patch reduces the footprint and makes sure the value is enough. Later patch to add RSS increases the number of possible Rx status elements.

Add an SKF_AD_HATYPE field to the packet ancilliary data area, giving access to skb->dev->type, as reported in the sll_hatype field. When capturing packets on a PF_PACKET/SOCK_RAW socket bound to all interfaces, there doesn't appear to be a way for the filter program to actually find out the underlying hardware type the packet was captured on. This patch adds such ability. This patch also handles the case where skb->dev can be NULL, such as on netlink sockets. Signed-off-by: Paul Evans <leonerd@leonerd.org.uk> Signed-off-by: David S.

This patch adds IPv6 support for RFC5082 Generalized TTL Security Mechanism. Not to users of mapped address; the IPV6 and IPV4 socket options are seperate. The server does have to deal with both IPv4 and IPv6 socket options and the client has to handle the different for each family. On client: int ttl = 255; getaddrinfo(argv[1], argv[2], &hint, &result); for (rp = result; rp != NULL; rp = rp->ai_next) { s = socket(rp->ai_family, rp->ai_socktype, rp->ai_protocol); if (s < 0) continue; if (rp->ai_family == AF_INET) { setsockopt(s, IPPROTO_IP, IP_TTL, &ttl, sizeof(ttl)); } else if (rp->ai_family == AF_INET6) { setsockopt(s, IPPROTO_IPV6, IPV6_UNICAST_HOPS, &ttl, sizeof(ttl))) } if (connect(s, rp->ai_addr, rp->ai_addrlen) == 0) { ... On server: int minttl = 255 - maxhops; getaddrinfo(NULL, port, &hints, &result); for (rp = result; rp != NULL; rp = rp->ai_next) { s = socket(rp->ai_family, rp->ai_socktype, rp->ai_protocol); if (s < 0) continue; if (rp->ai_family == AF_INET6) setsockopt(s, IPPROTO_IPV6, IPV6_MINHOPCOUNT, &minttl, sizeof(minttl)); setsockopt(s, IPPROTO_IP, IP_MINTTL, &minttl, sizeof(minttl)); if (bind(s, rp->ai_addr, rp->ai_addrlen) == 0) break ...

If some skb are queued to our backlog, we are delaying IPI sending at the end of net_rx_action(), increasing latencies. This defeats the queueing, since we want to quickly dispatch packets to the pool of worker cpus, then eventually deeply process our packets. It's better to send IPI before processing our packets in upper layers, from process_backlog(). Change the _and_disable_irq suffix to _and_enable_irq(), since we enable local irq in net_rps_action(), sorry for the confusion.

kill_fasync() uses a central rwlock, candidate for RCU conversion, to avoid cache line ping pongs on SMP. fasync_remove_entry() and fasync_add_entry() can disable IRQS on a short section instead during whole list scan. Use a spinlock per fasync_struct to synchronize kill_fasync_rcu() and fasync_{remove|add}_entry(). This spinlock is IRQ safe, so sock_fasync() doesnt need its own implementation and can use fasync_helper(), to reduce code size and complexity. We can remove __kill_fasync() direct use in net/socket.c, and rename it to kill_fasync_rcu(). Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Cc: Paul E.
