2011-06-09inetpeer: remove unused listEric Dumazet1-2/+0
Andi Kleen and Tim Chen reported huge contention on inetpeer unused_peers.lock, on memcached workload on a 40 core machine, with disabled route cache. It appears we constantly flip peers refcnt between 0 and 1 values, and we must insert/remove peers from unused_peers.list, holding a contended spinlock. Remove this list completely and perform a garbage collection on-the-fly, at lookup time, using the expired nodes we met during the tree traversal. This removes a lot of code, makes locking more standard, and obsoletes two sysctls (inet_peer_gc_mintime and inet_peer_gc_maxtime). This also removes two pointers in inet_peer structure. There is still a false sharing effect because refcnt is in first cache line of object [were the links and keys used by lookups are located], we might move it at the end of inet_peer structure to let this first cache line mostly read by cpus.

2011-05-09inet: Pass flowi to ->queue_xmit().David S. Miller1-1/+1
This allows us to acquire the exact route keying information from the protocol, however that might be managed. It handles all of the possibilities, from the simplest case of storing the key in inet->cork.fl to the more complex setup SCTP has where individual transports determine the flow.

2011-05-07inet: Decrease overhead of on-stack inet_cork.David S. Miller1-1/+1
When we fast path datagram sends to avoid locking by putting the inet_cork on the stack we use up lots of space that isn't necessary. This is because inet_cork contains a "struct flowi" which isn't used in these code paths. Split inet_cork to two parts, "inet_cork" and "inet_cork_full". Only the latter of which has the "struct flowi" and is what is stored in inet_sock. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Eric Dumazet <eric.dumazet@gmail.com>
2011-04-29inet: add RCU protection to inet->optEric Dumazet1-5/+6
We lack proper synchronization to manipulate inet->opt ip_options Problem is ip_make_skb() calls ip_setup_cork() and ip_setup_cork() possibly makes a copy of ipc->opt (struct ip_options), without any protection against another thread manipulating inet->opt. Another thread can change inet->opt pointer and free old one under us. Use RCU to protect inet->opt (changed to inet->inet_opt). Instead of handling atomic refcounts, just copy ip_options when necessary, to avoid cache line dirtying. We cant insert an rcu_head in struct ip_options since its included in skb->cb[], so this patch is large because I had to introduce a new ip_options_rcu structure.

2011-03-30net: gre: provide multicast mappings for ipv4 and ipv6Timo Teräs1-0/+8
My commit 6d55cb91a0020ac0 (gre: fix hard header destination address checking) broke multicast. The reason is that ip_gre used to get ipgre_header() calls with zero destination if we have NOARP or multicast destination. Instead the actual target was decided at ipgre_tunnel_xmit() time based on per-protocol dissection. Instead of allowing the "abuse" of ->header() calls with invalid destination, this creates multicast mappings for ip_gre. This also fixes "ip neigh show nud noarp" to display the proper multicast mappings used by the gre device.

2011-03-01inet: Add ip_make_skb and ip_finish_skbHerbert Xu1-0/+16
This patch adds the helper ip_make_skb which is like ip_append_data and ip_push_pending_frames all rolled into one, except that it does not send the skb produced. The sending part is carried out by ip_send_skb, which the transport protocol can call after it has tweaked the skb. It is meant to be called in cases where corking is not used should have a one-to-one correspondence to sendmsg. This patch also adds the helper ip_finish_skb which is meant to be replace ip_push_pending_frames when corking is required. Previously the protocol stack would peek at the socket write queue and add its header to the first packet. With ip_finish_skb, the protocol stack can directly operate on the final skb instead, just like the non-corking case with ip_make_skb.

2010-12-13ipv4: Don't pre-seed hoplimit metric.David S. Miller1-10/+0
Always go through a new ip4_dst_hoplimit() helper, just like ipv6. This allowed several simplifications: 1) The interim dst_metric_hoplimit() can go as it's no longer userd. 2) The sysctl_ip_default_ttl entry no longer needs to use ipv4_doint_and_flush, since the sysctl is not cached in routing cache metrics any longer. 3) ipv4_doint_and_flush no longer needs to be exported and therefore can be marked static. When ipv4_doint_and_flush_strategy was removed some time ago, the external declaration in ip.h was mistakenly left around so kill that off too. We have to move the sysctl_ip_default_ttl declaration into ipv4's route cache definition header net/route.h, because currently net/ip.h (where the declaration lives now) has a back dependency on net/route.h Signed-off-by: David S.

2010-07-01snmp: 64bit ipstats_mib for all archesEric Dumazet1-6/+14
/proc/net/snmp and /proc/net/netstat expose SNMP counters. Width of these counters is either 32 or 64 bits, depending on the size of "unsigned long" in kernel. This means user program parsing these files must already be prepared to deal with 64bit values, regardless of user program being 32 or 64 bit. This patch introduces 64bit snmp values for IPSTAT mib, where some counters can wrap pretty fast if they are 32bit wide. # netstat -s|egrep "InOctets|OutOctets" InOctets: 244068329096 OutOctets: 244069348848 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2010-06-11ip: ip_ra_control() rcu fixEric Dumazet1-1/+4
commit 66018506e15b (ip: Router Alert RCU conversion) introduced RCU lookups to ip_call_ra_chain(). It missed proper deinit phase : When ip_ra_control() deletes an ip_ra_chain, it should make sure ip_call_ra_chain() users can not start to use socket during the rcu grace period. It should also delay the sock_put() after the grace period, or we risk a premature socket freeing and corruptions, as raw sockets are not rcu protected yet. This delay avoids using expensive atomic_inc_not_zero() in ip_call_ra_chain(). Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-01-07ip: fix mc_loop checks for tunnels with multicast outer addressesOctavian Purdila1-0/+16
When we have L3 tunnels with different inner/outer families (i.e. IPV4/IPV6) which use a multicast address as the outer tunnel destination address, multicast packets will be loopbacked back to the sending socket even if IP*_MULTICAST_LOOP is set to disabled. The mc_loop flag is present in the family specific part of the socket (e.g. the IPv4 or IPv4 specific part). setsockopt sets the inner family mc_loop flag. When the packet is pushed through the L3 tunnel it will eventually be processed by the outer family which if different will check the flag in a different part of the socket then it was set.

2009-12-15netfilter: fix crashes in bridge netfilter caused by fragment jumpsPatrick McHardy1-0/+1
When fragments from bridge netfilter are passed to IPv4 or IPv6 conntrack and a reassembly queue with the same fragment key already exists from reassembling a similar packet received on a different device (f.i. with multicasted fragments), the reassembled packet might continue on a different codepath than where the head fragment originated. This can cause crashes in bridge netfilter when a fragment received on a non-bridge device (and thus with skb->nf_bridge == NULL) continues through the bridge netfilter code. Add a new reassembly identifier for packets originating from bridge netfilter and use it to put those packets in insolated queues.

2009-10-19inet: rename some inet_sock fieldsEric Dumazet1-6/+6
In order to have better cache layouts of struct sock (separate zones for rx/tx paths), we need this preliminary patch. 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.
