2018-07-03net: aquantia: Improve adapter init/deinit logicIgor Russkikh6-31/+66
We now pass link drop status to FW on init/deinit. This is required to inform FW that driver took/released a control on link. FW then will manage its own state and device power profile based on this information. To improve management we remove mpi_set function which ambiguously took both state and speed parameters. Deinit callback is now a part of FW ops, as it actually manages the FW. Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-07-02r8169: remove old PHY reset hackHeiner Kallweit1-56/+1
This hack (affecting the non-PCIe models only) was introduced in 2004 to deal with link negotiation failures in 1GBit mode. Based on a comment in the r8169 vendor driver I assume the issue affects RTL8169sb in combination with particular 1GBit switch models. Resetting the PHY every 10s and hoping that one fine day we will make it to establish the link seems to be very hacky to me. I'd say: If 1GBit doesn't work reliably in a users environment then the user should remove 1GBit from the advertised modes, e.g. by using ethtool -s <if> advertise <10/100 modes> If the issue affects one chip version only and that with most link partners, then we could also think of removing 1GBit from the advertised modes for this chip version in the driver.

2018-07-02ipvlan: call dev_change_flags when ipvlan mode is resetHangbin Liu1-8/+28
After we change the ipvlan mode from l3 to l2, or vice versa, we only reset IFF_NOARP flag, but don't flush the ARP table cache, which will cause eth->h_dest to be equal to eth->h_source in ipvlan_xmit_mode_l2(). Then the message will not come out of host. Here is the reproducer on local host: ip link set eth1 up ip addr add 192.168.1.1/24 dev eth1 ip link add link eth1 ipvlan1 type ipvlan mode l3 ip netns add net1 ip link set ipvlan1 netns net1 ip netns exec net1 ip link set ipvlan1 up ip netns exec net1 ip addr add 192.168.2.1/24 dev ipvlan1 ip route add 192.168.2.0/24 via 192.168.1.2 ping 192.168.2.2 -c 2 ip netns exec net1 ip link set ipvlan1 type ipvlan mode l2 ping 192.168.2.2 -c 2 Add the same configuration on remote host. After we set the mode to l2, we could find that the src/dst MAC addresses are the same on eth1: 21:26:06.648565 00:b7:13:ad:d3:05 > 00:b7:13:ad:d3:05, ethertype IPv4 (0x0800), length 98: (tos 0x0, ttl 64, id 58356, offset 0, flags [DF], proto ICMP (1), length 84) 192.168.2.1 > 192.168.2.2: ICMP echo request, id 22686, seq 1, length 64 Fix this by calling dev_change_flags(), which will call netdevice notifier with flag change info. v2: a) As pointed out by Wang Cong, check return value for dev_change_flags() when change dev flags. b) As suggested by Stefano and Sabrina, move flags setting before l3mdev_ops.

Since the addition of GRO for ESP, gro_receive can consume the skb and return -EINPROGRESS. In that case, the lower layer GRO handler cannot touch the skb anymore. Commit 5f114163f2f5 ("net: Add a skb_gro_flush_final helper.") converted some of the gro_receive handlers that can lead to ESP's gro_receive so that they wouldn't access the skb when -EINPROGRESS is returned, but missed other spots, mainly in tunneling protocols. This patch finishes the conversion to using skb_gro_flush_final(), and adds a new helper, skb_gro_flush_final_remcsum(), used in VXLAN and GUE.

2018-07-02Merge branch 'xps-symmretric-queue-selection'David S. Miller10-109/+505
Amritha Nambiar says: ==================== Symmetric queue selection using XPS for Rx queues This patch series implements support for Tx queue selection based on Rx queue(s) map. This is done by configuring Rx queue(s) map per Tx-queue using sysfs attribute. If the user configuration for Rx queues does not apply, then the Tx queue selection falls back to XPS using CPUs and finally to hashing. XPS is refactored to support Tx queue selection based on either the CPUs map or the Rx-queues map. The config option CONFIG_XPS needs to be enabled. By default no receive queues are configured for the Tx queue. - /sys/class/net/<dev>/queues/tx-*/xps_rxqs A set of receive queues can be mapped to a set of transmit queues (many:many), although the common use case is a 1:1 mapping. This will enable sending packets on the same Tx-Rx queue association as this is useful for busy polling multi-threaded workloads where it is not possible to pin the threads to a CPU. This is a rework of Sridhar's patch for symmetric queueing via socket option: https://www.spinics.net/lists/netdev/msg453106.html Testing Hints: Kernel: Linux 4.17.0-rc7+ Interface: driver: ixgbe version: 5.1.0-k firmware-version: 0x00015e0b Configuration: ethtool -L $iface combined 16 ethtool -C $iface rx-usecs 1000 sysctl net.core.busy_poll=1000 ATR disabled: ethtool -K $iface ntuple on Workload: Modified memcached that changes the thread selection policy to be based on the incoming rx-queue of a connection using SO_INCOMING_NAPI_ID socket option.

2018-07-02net-sysfs: Add interface for Rx queue(s) map per Tx queueAmritha Nambiar1-0/+83
Extend transmit queue sysfs attribute to configure Rx queue(s) map per Tx queue. By default no receive queues are configured for the Tx queue. - /sys/class/net/eth0/queues/tx-*/xps_rxqs Signed-off-by: Amritha Nambiar <amritha.nambiar@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-07-02net: Enable Tx queue selection based on Rx queuesAmritha Nambiar2-17/+55
This patch adds support to pick Tx queue based on the Rx queue(s) map configuration set by the admin through the sysfs attribute for each Tx queue. If the user configuration for receive queue(s) map does not apply, then the Tx queue selection falls back to CPU(s) map based selection and finally to hashing.

2018-07-02net: Record receive queue number for a connectionAmritha Nambiar4-0/+34
This patch adds a new field to sock_common 'skc_rx_queue_mapping' which holds the receive queue number for the connection. The Rx queue is marked in tcp_finish_connect() to allow a client app to do SO_INCOMING_NAPI_ID after a connect() call to get the right queue association for a socket. Rx queue is also marked in tcp_conn_request() to allow syn-ack to go on the right tx-queue associated with the queue on which syn is received.

2018-07-02net: sock: Change tx_queue_mapping in sock_common to unsigned shortAmritha Nambiar1-3/+11
Change 'skc_tx_queue_mapping' field in sock_common structure from 'int' to 'unsigned short' type with ~0 indicating unset and other positive queue values being set. This will accommodate adding a new 'unsigned short' field in sock_common in the next patch for rx_queue_mapping. Signed-off-by: Amritha Nambiar <amritha.nambiar@intel.com> Signed-off-by: David S.

2018-07-02net: Use static_key for XPS mapsAmritha Nambiar1-6/+25
Use static_key for XPS maps to reduce the cost of extra map checks, similar to how it is used for RPS and RFS. This includes static_key 'xps_needed' for XPS and another for 'xps_rxqs_needed' for XPS using Rx queues map. Signed-off-by: Amritha Nambiar <amritha.nambiar@intel.com> Signed-off-by: David S.
