      net: openvswitch: return an error instead of doing BUG_ON() · a734d1f4
      Eelco Chaudron authored
      For all other error cases in queue_userspace_packet() the error is
      returned, so it makes sense to do the same for these two error cases.

      ====================
      netlink: strict attribute checking follow-up
      
      Three follow-up patches for recent strict netlink validation series.
      
      Patch 1 fixes dump handling for genetlink families which validate and parse
      messages themselves (e.g. because they need different policies for diferent
      commands).
      
      Patch 2 sets bad_attr in extack in one place where this was omitted.
      
      Patch 3 adds new NL_VALIDATE_NESTED flags for strict validation to enable
      checking that NLA_F_NESTED value in received messages matches expectations
      and includes this flag in NL_VALIDATE_STRICT. This would change userspace
      visible behavior but the previous switching to NL_VALIDATE_STRICT for new
      code is still only in net-next at the moment.

      Add new validation flag NL_VALIDATE_NESTED which adds three consistency
      checks of NLA_F_NESTED_FLAG:
      
        - the flag is set on attributes with NLA_NESTED{,_ARRAY} policy

      genetlink: do not validate dump requests if there is no policy · 05d7f547
      Michal Kubecek authored
      Unlike do requests, dump genetlink requests now perform strict validation
      by default even if the genetlink family does not set policy and maxtype
      because it does validation and parsing on its own (e.g. because it wants to
      allow different message format for different commands). While the null
      policy will be ignored, maxtype (which would be zero) is still checked so
      that any attribute will fail validation.
      
      The solution is to only call __nla_validate() from genl_family_rcv_msg()
      if family->maxtype is set.

      ====================
      mlxsw: Firmware version update
      
      This patchset updates mlxsw to use a new firmware version and adds
      support for split into two ports on Spectrum-2 based systems.
      
      Patch #1 updates the firmware version to 13.2000.1122
      
      Patch #2 queries new resources from the firmware.
      
      Patch #3 makes use of these resources in order to support split into two
      ports on Spectrum-2 based systems. The need for these resources is
      explained by Shalom:
      
      When splitting a port, different local ports need to be mapped on different
      systems. For example:
      
      SN3700 (local_ports_in_2x=2):
        * Without split:
            front panel 1   --> local port 1
            front panel 2   --> local port 5
        * Split to 2:
            front panel 1s0 --> local port 1
            front panel 1s1 --> local port 3
            front panel 2   --> local port 5
      
      SN3800 (local_ports_in_2x=1):
        * Without split:
            front panel 1 --> local port 1
            front panel 2 --> local port 3
        * Split to 2:
            front panel 1s0 --> local port 1
            front panel 1s1 --> local port 2
            front panel 2   --> local port 3
      
      The local_ports_in_{1x, 2x} resources provide the offsets from the base
      local ports according to which the new local ports can be calculated.

      tipc: fix missing Name entries due to half-failover · c0b14a08
      Tuong Lien authored
      TIPC link can temporarily fall into "half-establish" that only one of
      the link endpoints is ESTABLISHED and starts to send traffic, PROTOCOL
      messages, whereas the other link endpoint is not up (e.g. immediately
      when the endpoint receives ACTIVATE_MSG, the network interface goes
      down...).
      
      This is a normal situation and will be settled because the link
      endpoint will be eventually brought down after the link tolerance time.
      
      However, the situation will become worse when the second link is
      established before the first link endpoint goes down,
      For example:
      
         1. Both links <1A-2A>, <1B-2B> down
         2. Link endpoint 2A up, but 1A still down (e.g. due to network
            disturbance, wrong session, etc.)
         3. Link <1B-2B> up
         4. Link endpoint 2A down (e.g. due to link tolerance timeout)
         5. Node B starts failover onto link <1B-2B>
      
         ==> Node A does never start link failover.
      
      When the "half-failover" situation happens, two consequences have been
      observed:
      
      a) Peer link/node gets stuck in FAILINGOVER state;
      b) Traffic or user messages that peer node is trying to failover onto
      the second link can be partially or completely dropped by this node.
      
      The consequence a) was actually solved by commit c140eb16 ("tipc:
      fix failover problem"), but that commit didn't cover the b). It's due
      to the fact that the tunnel link endpoint has never been prepared for a
      failover, so the 'l->drop_point' (and the other data...) is not set
      correctly. When a TUNNEL_MSG from peer node arrives on the link,
      depending on the inner message's seqno and the current 'l->drop_point'
      value, the message can be dropped (- treated as a duplicate message) or
      processed.
      At this early stage, the traffic messages from peer are likely to be
      NAME_DISTRIBUTORs, this means some name table entries will be missed on
      the node forever!
      
      The commit resolves the issue by starting the FAILOVER process on this
      node as well. Another benefit from this solution is that we ensure the
      link will not be re-established until the failover ends.

      net: phy: improve resuming from hibernation · f24098f8
      Heiner Kallweit authored
      I got an interesting report [0] that after resuming from hibernation
      the link has 100Mbps instead of 1Gbps. Reason is that another OS has
      been used whilst Linux was hibernated. And this OS speeds down the link
      due to WoL. Therefore, when resuming, we shouldn't expect that what
      the PHY advertises is what it did when hibernating.
      Easiest way to do this is removing state PHY_RESUMING. Instead always
      go via PHY_UP that configures PHY advertisement.

      net: phy: improve pause handling · 22c0ef6b
      Heiner Kallweit authored
      When probing the phy device we set sym and asym pause in the "supported"
      bitmap (unless the PHY tells us otherwise). However we don't know yet
      whether the MAC supports pause. Simply copying phy->supported to
      phy->advertising will trigger advertising pause, and that's not
      what we want. Therefore add phy_advertise_supported() that copies all
      modes but doesn't touch the pause bits.
      
      In phy_support_(a)sym_pause we shouldn't set any bits in the supported
      bitmap because we may set a bit the PHY intentionally disabled.
      Effective pause support should be the AND-combined PHY and MAC pause
      capabilities. If the MAC supports everything, then it's only relevant
      what the PHY supports. If MAC supports sym pause only, then we have to
      clear the asym bit in phydev->supported.
      Copy the pause flags only and don't touch the modes, because a driver
      may have intentionally removed a mode from phydev->advertising.

      net: add a generic tracepoint for TX queue timeout · 141b6b2a
      Cong Wang authored
      Although devlink health report does a nice job on reporting TX
      timeout and other NIC errors, unfortunately it requires drivers
      to support it but currently only mlx5 has implemented it.
      Before other drivers could catch up, it is useful to have a
      generic tracepoint to monitor this kind of TX timeout. We have
      been suffering TX timeout with different drivers, we plan to
      start to monitor it with rasdaemon which just needs a new tracepoint.

      ====================
      100GbE Intel Wired LAN Driver Updates 2019-05-02
      
      This series contains updates to the ice driver only.
      
      Anirudh introduces the framework to store queue specific information in
      the VSI queue contexts.  This will allow future changes to update the
      structure to hold queue specific information.
      
      Akeem adds additional check so that if there is no queue to disable when
      attempting to disable a queue, return a configuration error without
      acquiring the lock.  Fixed an issue with non-trusted VFs being able to
      add more than the permitted number of VLANs.
      
      Bruce removes unreachable code and updated the function to return void
      since it would never return anything but success.
      
      Brett provides most of the changes in the series, starting with reducing
      the scope of the error variable used and improved the debug message if
      we fail to configure the receive queue.  Updates the driver to use a
      macro instead of using the same 'for' loop throughout the driver which
      helps with readability.  Fixed an issue where users were led to believe
      they could set rx-usecs-high value, yet the changes to this value would
      not stick because it was not yet implemented to allow changes to this
      value, so implement the missing code to change the value.  Found we had
      unnecessary wait when disabling queues, so remove it.  I,proved a
      wasteful addition operation in our hot path by adding a member to the
      ice_q_vector structure and the necessary changes to use the member which
      stores the calculated vector hardware index.  Refactored the link event
      flow to make it cleaner and more clear.
      
      Maciej updates the array index when stopping transmit rings, so that
      process every ring the VSI, not just the rings in a given transmit
      class.
      
      Paul adds support for setting 52 byte RSS hash keys.
      
      Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register,
      since the interrupt handlers will handle resetting the bit, if
      necessary.
      
      Tony adds a missing PHY type, which was causing warning message about an
      unrecognized PHY.

      This patch adds support for FEC encoding control, user can change
      FEC mode by command ethtool --set-fec, and get FEC mode by command
      ethtool --show-fec. The fec capability is changed follow the port
      speed. If autoneg on, the user configure fec mode will be overwritten
      by autoneg result.

      net: hns3: add autoneg and change speed support for fibre port · 22f48e24
      Jian Shen authored
      Previously, our driver only supports phydev to autoneg or change
      port speed. This patch adds support for fibre port, driver gets
      media speed capability and autoneg capability from firmware. If
      the media supports multiple speeds, user can change port speed
      with command "ethtool -s <devname> speed xxxx autoneg off duplex
      full". If autoneg on, the user configuration may be overwritten
      by the autoneg result.

      net: hns3: add support for multiple media type · 88d10bd6
      Jian Shen authored
      Previously, we can only identify copper and fiber type, the
      supported link modes of port information are always showing
      SR type. This patch adds support for multiple media types,
      include SR, LR CR, KR. Driver needs to query the media type
      from firmware periodicly, and updates the port information.
      
      The new port information looks like this:
      Settings for eth0:
              Supported ports: [ FIBRE ]
              Supported link modes:   25000baseCR/Full
                                      25000baseSR/Full
                                      1000baseX/Full
                                      10000baseCR/Full
                                      10000baseSR/Full
                                      10000baseLR/Full
              Supported pause frame use: Symmetric
              Supports auto-negotiation: No
              Supported FEC modes: None BaseR
              Advertised link modes:  Not reported
              Advertised pause frame use: No
              Advertised auto-negotiation: No
              Advertised FEC modes: Not reported
              Speed: 10000Mb/s
              Duplex: Full
              Port: FIBRE
              PHYAD: 0
              Transceiver: internal
              Auto-negotiation: off
              Current message level: 0x00000036 (54)
                                     probe link ifdown ifup
              Link detected: yes
      
      In order to be compatible with old firmware which only support
      sfp speed, we remained using the same query command, and kept
      the former logic.

      usbnet: ipheth: Remove unnecessary NULL pointer check · e28441e2
      Guenter Roeck authored
      ipheth_carrier_set() is called from two locations. In
      ipheth_carrier_check_work(), its parameter 'dev' is set with
      container_of(work, ...) and can not be NULL. In ipheth_open(),
      dev is extracted from netdev_priv(net) and dereferenced before
      the call to ipheth_carrier_set(). The NULL pointer check of dev
      in ipheth_carrier_set() is therefore unnecessary and can be removed.

      Allow an interrupt number to be passed in the platform data. The
      driver will then use it if not zero, otherwise it will poll for
      interrupts.

      mv88e6xxx: Disable ports to save power
      
      Save some power by disabling ports. The first patch fully disables a
      port when it is runtime disabled. The second disables any ports which
      are not used at all.
      
      Depending on configuration strapping, this can lower the temperature
      of an idle switch a few degrees.

      net: dsa :mv88e6xxx: Disable unused ports · 100a9b9d
      Andrew Lunn authored
      If the NO_CPU strap is set, the switch starts in 'dumb hub' mode, with
      all ports enable. Ports which are then actively used are reconfigured
      as required when the driver starts. However unused ports are left
      alone. Change this to disable them, and turn off any SERDES
      interface. This could save some power and so reduce the temperature a
      bit.

      Jeff Kirsher says:
      
      ====================
      40GbE Intel Wired LAN Driver Updates 2019-05-03
      
      This series contains updates to the i40e driver only.
      
      Carolyn changes the driver behavior to now disable the VF after one MDD
      event instead of allowing a couple of MDD events before doing the reset.
      
      Aleksandr changes the driver to only report an error when a VF tries to
      remove VLAN when a port VLAN is configured, unless it is VLAN 0.  Also
      extends the LLDP support to be able to keep the current LLDP state
      persistent across a power cycle.
      
      Maciej fixes the checksum calculation due to firmware changes, which
      requires the driver to perform a double shadow RAM dump in some cases.
      
      Adam adds advertising support for 40GBase_LR4, 40GBase_CR4 and fibre in
      the driver.
      
      Jake cleans up a check that is not needed and was producing a warning in
      GCC 8.
      
      Harshitha fixes a misleading message by ensuring that a success message
      is only printed on the host side when the promiscuous mode change has
      been successful.
      
      Stefan Assmann adds the vendor id and device id to the dmesg log entry
      during probe to help with bug reports when lspci output may not be
      available.
      
      Alice and Piotr add recovery mode support in the i40e driver, which is
      needed for migrating from a structured to a flat firmware image.
      
      v2: Removed patch 1 "i40e: replace switch-statement to speed-up
          retpoline-enabled builds" from the series since it is no longer
          needed.  Also updated the last patch in the series that introduces
          recovery mode support, to include a more detailed patch description
          and removed code not intended for the upstream kernel.
