2015-03-30mac80211: stop scan before connectionDavid Spinadel1-0/+4
Stop scan before authentication or association to make sure that nothing interferes with connection flow. Currently mac80211 defers RX auth and assoc packets (among other ones) until after the scan is complete, so auth during scan is likely to fail if scan took too much time.

2015-03-30mac80211: agg-tx: avoid sending DelBA with sta->lock heldJohannes Berg1-2/+7
The rate control locking caused a potential deadlock here due to the locks being acquired in different orders, so that change cannot yet be applied. However, there's no fundamental reason for this code to hold the sta->lock while transmitting frames. Clearly it's better not to hold the lock for longer periods of time, which can happen here since we call all the way down to the driver. Change the code a bit to not hold it while doing that.

2015-03-29tipc: fix two bugs in secondary destination lookupJon Paul Maloy3-1/+14
A message sent to a node after a successful name table lookup may still find that the destination socket has disappeared, because distribution of name table updates is non-atomic. If so, the message will be rejected back to the sender with error code TIPC_ERR_NO_PORT. If the source socket of the message has disappeared in the meantime, the message should be dropped. However, in the currrent code, the message will instead be subject to an unwanted tertiary lookup, because the function tipc_msg_lookup_dest() doesn't check if there is an error code present in the message before performing the lookup. In the worst case, the message may now find the old destination again, and be redirected once more, instead of being dropped directly as it should be. A second bug in this function is that the "prev_node" field in the message is not updated after successful lookup, something that may have unpredictable consequences. The problems arising from those bugs occur very infrequently. The third change in this function; the test on msg_reroute_msg_cnt() is purely cosmetic, reflecting that the returned value never can be negative. This commit corrects the two bugs described above.

2015-03-29net: fec: setup right value for mdio hold timeUwe Kleine-König1-3/+27
The FEC modules used on i.MX28 and newer have a register to tune the MDIO output hold time that should be at least 10 ns. Up to now this value was not explicitly set and so resulted in less hold time if the fec clock was faster than 100 MHz. This was noticed on an i.MX28 machine that uses an input clock of ~150 Mhz which resulted in unreliable communication with a Marvell switch.

2015-03-29net: tcp6: fix double call of tcp_v6_fill_cb()Alexey Kodanev1-0/+11
tcp_v6_fill_cb() will be called twice if socket's state changes from TCP_TIME_WAIT to TCP_LISTEN. That can result in control buffer data corruption because in the second tcp_v6_fill_cb() call it's not copying IP6CB(skb) anymore, but 'seq', 'end_seq', etc., so we can get weird and unpredictable results. Performance loss of up to 1200% has been observed in LTP/vxlan03 test. This can be fixed by copying inet6_skb_parm to the beginning of 'cb' only if xfrm6_policy_check() and tcp_v6_fill_cb() are going to be called again.

Toshiaki Makita says: ==================== Stacked vlan TSO On the basis of Netdev 0.1 discussion[1], I made a patch set to enable TSO for packets with multiple vlans. Currently, packets with multiple vlans are always segmented by software, which is caused by that netif_skb_features() drops most feature flags for multiple tagged packets. To allow NICs to segment them, we need to get rid of that check from core. Fortunately, recently introduced ndo_features_check() can be used to move the check to each driver, and this patch set is based on the idea. For the initial patch set, I chose 3 drivers, bonding, team, and igb, as candidates to enable TSO. I tested them and confirmed they works fine with this change. Here are samples of performance test results. As I expected, %sys gets pretty lower than before. * TEST1: vlan (.1Q) on vlan (.1ad) on igb (I350) - before $ netperf -t TCP_STREAM -H 192.168.10.1 -l 60 Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 60.02 933.72 Average: CPU %user %nice %system %iowait %steal %idle Average: all 0.13 0.00 11.28 0.01 0.00 88.58 - after $ netperf -t TCP_STREAM -H 192.168.10.1 -l 60 Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 60.01 936.13 Average: CPU %user %nice %system %iowait %steal %idle Average: all 0.24 0.00 4.17 0.01 0.00 95.58 * TEST2: vlan (.1Q) on bridge (.1ad vlan filtering) on team on igb (I350) - before $ netperf -t TCP_STREAM -H 192.168.10.1 -l 60 Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 60.01 936.28 Average: CPU %user %nice %system %iowait %steal %idle Average: all 0.41 0.00 11.57 0.01 0.00 88.01 - after $ netperf -t TCP_STREAM -H 192.168.10.1 -l 60 Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 60.02 935.72 Average: CPU %user %nice %system %iowait %steal %idle Average: all 0.14 0.00 7.66 0.01 0.00 92.19 In addition to above, I tested these configurations: - vlan (.1Q) on vlan (1.ad) on bonding on igb (I350) - vlan (.1Q) on vlan (1.Q) on igb (I350) - vlan (.1Q) on vlan (1.Q) on team on igb (I350) And didn't find any problem.

2015-03-29vlan: Add features for stacked vlan deviceToshiaki Makita1-0/+1
Stacked vlan devices curretly have few features (GRO, HIGHDMA, LLTX). Since we have software fallbacks in case the NIC can not handle some features for multiple vlans, we can add the same features as the lower vlan devices for stacked vlan devices. This allows stacked vlan devices to create large (GSO) packets and not to segment packets. Those packets will be segmented by software on the real device, or even can be segmented by the NIC once TSO for multiple vlans becomes enabled by the following patches. The exception is those related to FCoE, which does not have a software fallback. Signed-off-by: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp> Signed-off-by: David S. Miller <davem@davemloft.net>

For the most part this factors out common port initialization code. There is no functional change except for patch 3, which disables the message port bit for the CPU port to prevent packet duplication if HW bridging is configured. Patch 8 adds the infrastructure for hardware bridging support to the mv88e6xxx code. Patch 9 wires the MV88E6352 driver to support hardware bridging. Patches 10 to 12 add support for ndo_fdb functions to the dsa subsystem, and wire up the MV88E6352 driver to support those functions.

2015-03-29net: dsa: mv88e6xxx: Disable Message Port bit for CPU portGuenter Roeck1-4/+3
Datasheet says that the Message Port bit should not be set for the CPU port. Having it set causes DSA tagged packets to be sent to the CPU port roughly every 30 seconds. Those packets are the same as real packets forwarded between switch ports if the switch is configured for switching between multiple ports. The packets are then bridged by the software bridge, resulting in duplicated packets on the network.

Provide mv88e6xxx_setup_port_common() for common port initialization. Currently only write Port 1 Control and VLAN configuration since this will be needed for hardware bridging. More can be added later if desired/needed. Reviewed-by: Andrew Lunn <andrew@lunn.ch> Tested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: David S.

2015-03-29hv_netvsc: remove vmbus_are_subchannels_present() in rndis_filter_device_add()Haiyang Zhang1-2/+0
The vmbus_are_subchannels_present() also involves opening the channels, which may be too early at this point. Checking for subchannels is not necessary here. So this patch removes it. Subchannels will be opened when offer messages arrive. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-29net: smc91x: make use of 4th parameter to devm_gpiod_get_indexUwe Kleine-König1-17/+8
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Simplify accordingly. Moreover use devm_gpiod_get_index_optional for still simpler handling. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: David S.
