2014-07-07net: fec: clean up transmit descriptor setupRussell King
Avoid writing any state until we're certain we can proceed with the transmission: this avoids writing mapping error address values to the descriptors, or setting the skbuff pointer until we have successfully mapped the skb.

2014-07-07net: fec: make rx skb handling more robustRussell King
Allocate, and then map the receive skb before writing any data to the ring descriptor or storing the skb. When freeing the receive ring entries, unmap and free the skb, and then clear the stored skb pointer. This means we have ring data and skb pointer in one of two states: either both fully setup, or nothing setup. This simplifies the cleanup, as we can use just the skb pointer to indicate whether the descriptor is setup, and thus avoids potentially calling dma_unmap_single() on a DMA error value.

2014-07-07net: fec: remove useless fep->openedRussell King
napi_disable() waits until the NAPI processing has completed, and then prevents any further polls. At this point, the driver then clears fep->opened. The NAPI poll function uses this to stop processing in the receive path. Hence, it will never see this variable cleared, because the NAPI poll has to complete before it will be cleared. Therefore, this variable serves no purpose, so let's remove it. Acked-by: Fugang Duan <B38611@freescale.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: David S.

2014-07-07net: fec: stop the phy before shutting down the MACRussell King
When the network interface goes down, stop the phy to prevent further link up status changes before taking the MAC or netif sections down. This prevents further reception of link up events which could potentially call fec_restart(). Since phy_stop() takes the mutex which adjust_link() runs under, we also ensure that adjust_link() will not already be processing a link up event. We also need to do this when suspending as well - we don't want a mis-timed phy state change to restart the MAC after we have stopped it for suspend, and thus need to restart the phy when resuming.

2014-07-07net: fec: remove checking for NULL phy_dev in fec_enet_close()Russell King
fep->phy_dev can not be NULL here for two reasons: - fec_enet_open() will have successfully connected the phy, or will have failed. - fec_enet_open() will have called phy_start(fep->phy_dev), which unconditionally dereferences this pointer. If it were to be NULL here, then fec_enet_open() will have already oopsed.

2014-07-07net: fec: use netif_tx_disable() rather than netif_stop_queue()Russell King
We use netif_stop_queue() in several places where we want to ensure that the start_xmit function is not running. netif_stop_queue() is not sufficient to achieve that - it merely sets a flag to indicate that the transmit queue(s) should not be run. netif_tx_disable() gives this guarantee, since it takes the transmit queue lock while marking the queue stopped. This will wait for the transmit function to complete before returning. Acked-by: Fugang Duan <B38611@freescale.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: David S.

2014-07-07net: fec: fix interrupt handling racesRussell King
While running: while :; do iperf -c <HOST> -P 4; done, transmit timeouts are regularly reported. With the tx ring dumping in place, we can see that all entries are in use, and the hardware has finished transmitting these packets. However, the driver has not reclaimed these ring entries. This can occur if the interrupt handler is invoked at the wrong moment - eg: CPU0 CPU1 fec_enet_tx() interrupt, IEVENT = FEC_ENET_TXF FEC_ENET_TXF cleared napi_schedule_prep() napi_complete() The result is that we clear the transmit interrupt, but we don't trigger any cleaning of the transmit ring. Instead, use a different strategy: - When receiving a transmit or receive interrupt, disable both tx and rx interrupts, but do not acknowledge them. Schedule a napi poll. Don't loop. - When we are polled, read IEVENT, acknowledging the pending transmit and receive interrupts, before then going on to process the appropriate rings. This allows us to avoid the race, and has a number of other advantages: - we cut down on the number of transmit interrupts we have to process. - we only look at the rings which have pending events. - we gain additional throughput: the iperf total bandwidth increases from about 180Mbps to 240Mbps: [ 3] 0.0-10.0 sec 68.1 MBytes 57.0 Mbits/sec [ 5] 0.0-10.0 sec 72.4 MBytes 60.5 Mbits/sec [ 4] 0.0-10.1 sec 76.1 MBytes 63.5 Mbits/sec [ 6] 0.0-10.1 sec 71.9 MBytes 59.9 Mbits/sec [SUM] 0.0-10.1 sec 288 MBytes 241 Mbits/sec Acked-by: Fugang Duan <B38611@freescale.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: David S.

2014-07-07net: fec: fix ethtool set_pauseparam duplex bugRussell King
Setting the pause parameters causes a running network interface to be restarted. However, the restart forces the FEC into half-duplex mode, whether or not the remote end is in half-duplex mode.

Tom Herbert says: ==================== net: Improvements and applications of packet flow hash in transmit path This patch series includes some patches which improve and make use of skb->hash in the transmit path. What is included: - Infrastructure to save a precomputed hash in the sock structure. For connected TCP and UDP sockets we only need to compute the flow hash once and not once for every packet. - Call skb_get_hash in get_xps_queue and __skb_tx_hash. This eliminates the awkward access to skb->sk->sk_hash in the lower transmit path. - Move UDP source port generation into a common function in udp.h This implementation is mostly based on vxlan_src_port. - Use non-zero IPv6 flow labels in flow_dissector as port information for flow hash calculation. - Implement automatic flow label generation on transmit (per RFC 6438). - Don't repeatedly try to compute an L4 hash in skb_get_hash if we've already tried to find one in software stack calculation. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-07net: Only do flow_dissector hash computation once per packetTom Herbert

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.

2014-07-07udp: 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.

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.

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.

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.
