2014-07-07net: Only do flow_dissector hash computation once per packetTom Herbert
Add sw_hash flag to skbuff to indicate that skb->hash was computed from flow_dissector. This flag is checked in skb_get_hash to avoid repeatedly trying to compute the hash (ie. in the case that no L4 hash can be computed).

2014-07-07ipv6: Implement automatic flow label generation on transmitTom Herbert
Automatically generate flow labels for IPv6 packets on transmit. The flow label is computed based on skb_get_hash. The flow label will only automatically be set when it is zero otherwise (i.e. flow label manager hasn't set one). This supports the transmit side functionality of RFC 6438. Added an IPv6 sysctl auto_flowlabels to enable/disable this behavior system wide, and added IPV6_AUTOFLOWLABEL socket option to enable this functionality per socket. By default, auto flowlabels are disabled to avoid possible conflicts with flow label manager, however if this feature proves useful we may want to enable it by default. It should also be noted that FreeBSD has already implemented automatic flow labels (including the sysctl and socket option). In FreeBSD, automatic flow labels default to enabled. Performance impact: Running super_netperf with 200 flows for TCP_RR and UDP_RR for IPv6. Note that in UDP case, __skb_get_hash will be called for every packet with explains slight regression. In the TCP case the hash is saved in the socket so there is no regression. Automatic flow labels disabled: TCP_RR: 86.53% CPU utilization 127/195/322 90/95/99% latencies 1.40498e+06 tps UDP_RR: 90.70% CPU utilization 118/168/243 90/95/99% latencies 1.50309e+06 tps Automatic flow labels enabled: TCP_RR: 85.90% CPU utilization 128/199/337 90/95/99% latencies 1.40051e+06 UDP_RR 92.61% CPU utilization 115/164/236 90/95/99% latencies 1.4687e+06 Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S.

2014-07-07flow_dissector: Use IPv6 flow label in flow_dissectorTom Herbert
This patch implements the receive side to support RFC 6438 which is to use the flow label as an ECMP hash. If an IPv6 flow label is set in a packet we can use this as input for computing an L4-hash. There should be no need to parse any transport headers in this case. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-07vxlan: Call udp_flow_src_portTom Herbert

2014-07-07udp: Add function to make source port for UDP tunnelsTom Herbert
This patch adds udp_flow_src_port function which is intended to be a common function that UDP tunnel implementations call to set the source port. The source port is chosen so that a hash over the outer headers (IP addresses and UDP ports) acts as suitable hash for the flow of the encapsulated packet. In this manner, UDP encapsulation works with RSS and ECMP based wrt the inner flow. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-07net: Call skb_get_hash in get_xps_queue and __skb_tx_hashTom Herbert

2014-07-07net: Save TX flow hash in sock and set in skbuf on xmitTom Herbert
For a connected socket we can precompute the flow hash for setting in skb->hash on output. This is a performance advantage over calculating the skb->hash for every packet on the connection. The computation is done using the common hash algorithm to be consistent with computations done for packets of the connection in other states where thers is no socket (e.g. time-wait, syn-recv, syn-cookies). This patch adds sk_txhash to the sock structure. inet_set_txhash and ip6_set_txhash functions are added which are called from points in TCP and UDP where socket moves to established state. skb_set_hash_from_sk is a function which sets skb->hash from the sock txhash value. This is called in UDP and TCP transmit path when transmitting within the context of a socket. Tested: ran super_netperf with 200 TCP_RR streams over a vxlan interface (in this case skb_get_hash called on every TX packet to create a UDP source port). Before fix: 95.02% CPU utilization 154/256/505 90/95/99% latencies 1.13042e+06 tps Time in functions: 0.28% skb_flow_dissect 0.21% __skb_get_hash After fix: 94.95% CPU utilization 156/254/485 90/95/99% latencies 1.15447e+06 Neither __skb_get_hash nor skb_flow_dissect appear in perf Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S.

2014-07-07flow_dissector: Abstract out hash computationTom Herbert
Move the hash computation located in __skb_get_hash to be a separate function which takes flow_keys as input. This will allow flow hash computation in other contexts where we only have addresses and ports. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-07-07tipc: fix link acknowledge logic in receive pathErik Hugne
Link state acks triggered from the receive path is done before the last received packet have been processed by the link layer. The effect of this is that the last received packet will not be included in the ack. This causes problems if the link window is set to TIPC_MIN_LINK_WIN, where the ack interval will be equal to the link tolerance, and the link enters a stop-and-go behavior. We move the ack logic to after link state processing, just before the packet is delivered to higher layers.

2014-07-07tcp: switch snt_synack back to measuring transmit time of first SYNACKNeal Cardwell
Always store in snt_synack the time at which the server received the first client SYN and attempted to send the first SYNACK. Recent commit aa27fc501 ("tcp: tcp_v[46]_conn_request: fix snt_synack initialization") resolved an inconsistency between IPv4 and IPv6 in the initialization of snt_synack. This commit brings back the idea from 843f4a55e (tcp: use tcp_v4_send_synack on first SYN-ACK), which was going for the original behavior of snt_synack from the commit where it was added in 9ad7c049f0f79 ("tcp: RFC2988bis + taking RTT sample from 3WHS for the passive open side") in v3.1. In addition to being simpler (and probably a tiny bit faster), unconditionally storing the time of the first SYNACK attempt has been useful because it allows calculating a performance metric quantifying how long it took to establish a passive TCP connection.

Function rt2800usb_autorun_detect() passes the address of a variable allocated onto the stack to be used for DMA by the USB layer. This has been caught by my debugging-enabled kernel. This patch change things in order to allocate that variable via kmalloc, and it adjusts things to handle the kmalloc failure case, propagating the error.

The comment was not accurate, we are talking about the frames *for* the station and not from the station. Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-07-07iwlwifi: mvm: remove 8000 HW family setting of adc sampling on nic configLiad Kaufman
This patch removes the setting of the ADC sampling bits in the mvm nic configuration. This setting is not required by the firmware, and furthermore - it interferes with the DBGC when it is running in DRAM mode on PCIe.

2014-07-07iwlwifi: mvm: disallow new TDLS stations when appropriateArik Nemtsov
HW/FW constraints dictate that TDLS should only be used when a single phy ctx is active. We also support at most 4 TDLS peers. We don't support TDLS on a P2P vif. Unify and move a phy-ctx counting implementation from the power-mgmt code in order to simplify implementation.
