2014-01-04Merge branch 'tunnel_dst_caching'David S. Miller2-24/+116
Tom Herbert says: ==================== ipv4: Cache dst in tunnels Version 3 of caching routes in tunnels. Addressed some comments from Eric in this series. There are two patches (variants) in the series: 1) One dst cached for each tunnel. 2) Percpu dst cache per tunnel to avoid false sharing Testing with GRE tunnels on a 32 CPU host with bnx2x (RSS support for GRE) shows a modest improvement in CPU utilization with these patches running 200 TCP_RR netperf clients.

2014-01-04ipv4: Cache dst in tunnelsTom Herbert2-24/+92
Avoid doing a route lookup on every packet being tunneled. In ip_tunnel.c cache the route returned from ip_route_output if the tunnel is "connected" so that all the rouitng parameters are taken from tunnel parms for a packet. Specifically, not NBMA tunnel and tos is from tunnel parms (not inner packet). Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-01-04sctp: Add process name and pid to deprecation warningsNeil Horman1-6/+18
Recently I updated the sctp socket option deprecation warnings to be both a bit more clear and ratelimited to prevent user processes from spamming the log file. Ben Hutchings suggested that I add the process name and pid to these warnings so that users can tell who is responsible for using the deprecated apis. This patch accomplishes that.

2014-01-02mlx4_en: Add PTP hardware clockShawn Bohrer4-8/+198
This adds a PHC to the mlx4_en driver. We use reader/writer spinlocks to protect the timecounter since every packet received needs to call timecounter_cycle2time() when timestamping is enabled. This can become a performance bottleneck with RSS and multiple receive queues if normal spinlocks are used. This driver has been tested with both Documentation/ptp/testptp and the linuxptp project (http://linuxptp.sourceforge.net/) on a Mellanox ConnectX-3 card.

2014-01-02ipv4: arp: update neighbour address when a gratuitous arp is received and ↵Salam Noureddine1-5/+10
arp_accept is set Gratuitous arp packets are useful in switchover scenarios to update client arp tables as quickly as possible. Currently, the mac address of a neighbour is only updated after a locktime period has elapsed since the last update. In most use cases such delays are unacceptable for network admins. Moreover, the "updated" field of the neighbour stucture doesn't record the last time the address of a neighbour changed but records any change that happens to the neighbour. This is clearly a bug since locktime uses that field as meaning "addr_updated". With this observation, I was able to perpetuate a stale address by sending a stream of gratuitous arp packets spaced less than locktime apart. With this change the address is updated when a gratuitous arp is received and the arp_accept sysctl is set.
