This can be used to force packets with a local destination out on the wire instead of routing them to loopback. Additionally this patch allows to recreate rules with a priority of 0. Combined with the previous patch to allow oif classification, a socket can be bound to the desired interface and packets routed to the wire like this: # move local rule to lower priority ip rule add pref 1000 lookup local ip rule del pref 0 # route packets of sockets bound to eth0 to the wire independant # of the destination address ip rule add pref 100 oif eth0 lookup 100 ip route add default dev eth0 table 100 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| * | TCPCT part 1d: define TCP cookie option, extend existing struct'sWilliam Allen Simpson2009-12-03

For example, the struct tcp_options_received cookie_plus variable fits between existing 16-bit and 8-bit variables, requiring no additional space (taking alignment into consideration). There are no additions to tcp_request_sock, and only 1 pointer in tcp_sock. This is a significantly revised implementation of an earlier (year-old) patch that no longer applies cleanly, with permission of the original author (Adam Langley): http://thread.gmane.org/gmane.linux.network/102586 The principle difference is using a TCP option to carry the cookie nonce, instead of a user configured offset in the data. This is more flexible and less subject to user configuration error. Such a cookie option has been suggested for many years, and is also useful without SYN data, allowing several related concepts to use the same extension option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add optional function parameters associated with sending SYNACK. These parameters are not needed after sending SYNACK, and are not used for retransmission. Avoids extending struct tcp_request_sock, and avoids allocating kernel memory. Also affects DCCP as it uses common struct request_sock_ops, but this parameter is currently reserved for future use.

If too many sockets are listed, we take a look at the secondary (port, address) hash chain. We choose the shortest chain and proceed with a RCU lookup on the elected chain. But, if we chose (port, address) chain, and fail to find a socket on given address, we must try another lookup on (port, in6addr_any) chain to find sockets not bound to a particular IP. -> No extra cost for typical setups, where the first lookup will probabbly be performed.

Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sock_queue_rcv_skb() can update sk_drops itself, removing need for callers to take care of it. This is more consistent since sock_queue_rcv_skb() also reads sk_drops when queueing a skb. This adds sk_drops managment to many protocols that not cared yet.
