Ursula Braun says: ==================== patches 2018-05-23 here are more smc-patches for net-next: Patch 1 fixes an ioctl problem detected by syzbot. Patch 2 improves smc_lgr_list locking in case of abnormal link group termination. If you want to receive a version for the net-tree, please let me know. It would look somewhat different, since the port terminate code has been moved to smc_core.c on net-next. Patch 3 enables SMC to deal with urgent data. Patch 4 is a minor improvement to avoid out-of-sync linkgroups between 2 peers. ==================== Signed-off-by: -

Client link group creation always follows the server linkgroup creation. If peer creates a new server link group, client has to create a new client link group. If peer reuses a server link group for a new connection, client has to reuse its client link group as well. To avoid out-of-sync conditions for link groups a longer delay for for client link group removal is defined to make sure this link group still exists, once the peer decides to reuse a server link group. Currently the client link group delay time is just 10 jiffies larger than the server link group delay time. This patch increases the delay difference to 10 seconds to have a better protection against out-of-sync link groups. Signed-off-by:

A connected SMC-socket contains addresses of descriptors for the send buffer and the rmb (receive buffer). Fields of these descriptors are used to determine the answer for certain ioctl requests. Add extra handling for unconnected SMC socket states without valid buffer descriptor addresses. Signed-off-by:

MDI Port Capabilities bit definitions were inconsistent with regard to the MDI enum values. 2 bits used to define MDI in the port capabilities are not really separable, it's a 2-bit field with 4 different values. Change the port capability bit definitions to be "AUTO" and "STRAIGHT" in order to get them to line up with the enum's. Signed-off-by:

Michal Vokáč says: ==================== Add support for QCA8334 switch This series basically adds support for a QCA8334 ethernet switch to the qca8k driver. It is a four-port variant of the already supported seven port QCA8337. Register map is the same for the whole familly and all chips have the same device ID. Major part of this series enhances the CPU port setting. Currently the CPU port is not set to any sensible defaults compatible with the xGMII interface. This series forces the CPU port to its maximum bandwidth and also allows to adjust the new defaults using fixed-link device tree sub-node. Alongside these changes I fixed two checkpatch warnings regarding SPDX and redundant parentheses. Changes in v3: - Rebased on latest net-next/master. - Corrected fixed-link documentation. ==================== Signed-off-by: -

By default autonegotiation is enabled to configure MAC on all ports. For the CPU port autonegotiation can not be used so we need to set some sensible defaults manually. This patch forces the default setting of the CPU port to 1000Mbps/full duplex which is the chip maximum capability. Also correct size of the bit field used to configure link speed.

Recent discussions around uevent filtering (cf. net-next commit [1], [2], and [3] and discussions in [4], [5], and [6]) have shown that the semantics around uevent filtering where not well understood. Now that we have settled - at least for the moment - how uevent filtering should look like let's add some selftests to ensure we don't regress anything in the future. Note, the semantics of uevent filtering are described in detail in my commit message to [2] so I won't repeat them here.

Roopa Prabhu says: ==================== fib rule selftest This series adds a new test to test fib rules. ip route get is used to test fib rule matches. This series also extends ip route get to match on sport and dport to test recent support of sport and dport fib rule match. v2 - address ido's commemt to make sport dport ip route get to work correctly for input route get. I don't support ip route get on ip-proto match yet. ip route get creates a udp packet and i have left it at that. We could extend ip route get to support a few ip proto matches in followup patches. v3 - Support ip_proto (only tcp and udp) match in getroute. dropped printing of new match attrs in ip route get, because ipv6 does not print it. And ipv6 currrently shares the dump api with ipv6 notify and its better to not add them to the notify api. dropped it to keep the api consistent between ipv4 and ipv6 (though uid is already printed in the ipv4 case). If we need it, both ipv4 and ipv6 can be enhanced to provide a separate get api. Moved skb creation for ipv4 to a separate func. v4 - drop separate skb for netlink and fix concerns around rcu and netlink reply (as pointed out by DaveM). I now try to reset the skb after the route lookup and before the netlink send (testing shows this is ok. More eyes and any feedback here will be helpful) v5 - dropped RTA_TABLE ipv4_rtm_policy update from this series and posted it separately for net (feedback from Eric) ==================== Signed-off-by: -

Until the udp receive stack supports large packets (UDP GRO), GSO packets must not loop from the egress to the ingress path. Revert the change that added NETIF_F_GSO_UDP_L4 to various virtual devices through NETIF_F_GSO_ENCAP_ALL as this included devices that may loop packets, such as veth and macvlan. Instead add it to specific devices that forward to another device's egress path, bonding and team.

This patch makes the i2c-bus property mandatory when using a device tree. If the sfp i2c bus isn't described it's impossible to guess the protocol to use for a given module, and the sfp module would then not work in most cases. Signed-off-by:

In case no Tx disable pin is available the SFP modules will always be emitting. This could be an issue when using modules using laser as their light source as we would have no way to disable it when the fiber is removed. This patch adds a warning when registering an SFP cage which do not have its tx_disable pin wired or available. Signed-off-by:

Jakub Kicinski says: ==================== nfp: abm: add basic support for advanced buffering NIC This series lays groundwork for advanced buffer management NIC feature. It makes necessary NFP core changes, spawns representors and adds devlink glue. Following series will add the actual buffering configuration (patch series size limit). First three patches add support for configuring NFP buffer pools via a mailbox. The existing devlink APIs are used for the purpose. Third patch allows us to perform small reads from the NFP memory. The rest of the patch set adds eswitch mode change support and makes the driver spawn appropriate representors. ==================== Signed-off-by: -

When NFP is modelled as a switch we assign phys_port_name to respective port(representor )s: vNIC0 - | - PF port (pf%d) MAC/PHY (p%d[s%d]) - |E== In most cases there is only one vNIC for communication with the switch. If there is more than one we need to be able to identify them. Use %d as phys_port_name of the vNICs. We don't have to pass ID to nfp_net_debugfs_vnic_add() separately any more. Signed-off-by:

PCI PFs can host more than one logical endpoint. In NFP terms this means having more than one vNIC for PCIe PF. The vNICs are usually corresponding 1:1 to Ethernet ports. In core NIC we use the legacy idea of vNIC *being* the Ethernet port, hence netdevs put pX(sY) in their phys_port_name, like Ethernet ports would. When ASIC ports are fully represented we need to be able to name different PCIe PF ports, too. Use a scheme similar to Ethernet ports - pfXsY, for PCIe PF number X, sub-port Y. Signed-off-by:

Current control firmware does not cater too well to multi-host applications. There is no way to check which hosts are up or otherwise negotiate what the state of the external port (the Ethernet port) should be. Make sure the link is up when driver loads, and don't take it down when Ethernet port netdev is closed. Signed-off-by:

To configure buffering points we need full set of netdevs: ASIC user netdev -- | -- PCIe port MAC port -- | -- Configuring egrees qdiscs on user netdev configures standard Linux TC software qdiscs, configuring PCIe port qdiscs will provide a way of setting ASIC queuing parameters for PCIe block. MAC port netdev egress qdiscs correspond to ASIC MAC Traffic Manager block. Signed-off-by: -

Our previous apps all assumed to use only one eswitch mode (legacy or switchdev) without the ability to change it. ABM NIC will want to support the switch so plumb devlink_eswitch_mode_set through. The devlink_eswitch_mode_set is expected to spawn representors and potentially devlink ports so it's called under big devlink lock and pf->lock. Signed-off-by:

Changing switch mode may want to register and unregister devlink ports. Therefore similarly to DEVLINK_CMD_PORT_SPLIT/UNSPLIT it should not take the instance lock. Drivers don't depend on existing locking since it's a very recent addition. Signed-off-by:
