      net: thunderx: Fix broken of_node_put() code. · 65c66af6
      David Daney authored
      commit b7d3e3d3
       ("net: thunderx: Don't leak phy device references
      on -EPROBE_DEFER condition.") incorrectly moved the call to
      of_node_put() outside of the loop.  Under normal loop exit, the node
      has already had of_node_put() called, so the extra call results in:

      net: ipv6: Do not keep linklocal and loopback addresses · 70af921d
      David Ahern authored
      f1705ec1 added the option to retain user configured addresses on an
      admin down. A comment to one of the later revisions suggested using the
      IFA_F_PERMANENT flag rather than adding a user_managed boolean to the
      ifaddr struct. A side effect of this change is that link local and
      loopback addresses are also retained which is not part of the objective
      of f1705ec1. Add check to drop those addresses.

      net: vrf: Fix dev refcnt leak due to IPv6 prefix route · 4f7f34ea
      David Ahern authored
      ifupdown2 found a kernel bug with IPv6 routes and movement from the main
      table to the VRF table. Sequence of events:
      Create the interface and add addresses:
          ip link add dev eth4.105 link eth4 type vlan id 105
          ip addr add dev eth4.105
          ip -6 addr add dev eth4.105 2008:105:105::10/64
      At this point IPv6 has inserted a prefix route in the main table even
      though the interface is 'down'. From there the VRF device is created:
          ip link add dev vrf105 type vrf table 105
          ip addr add dev vrf105
          ip -6 addr add dev vrf105 2000:9:105::10/128
          ip link set vrf105 up
      Then the interface is enslaved, while still in the 'down' state:
          ip link set dev eth4.105 master vrf105
      Since the device is down the VRF driver cycling the device does not
      send the NETDEV_UP and NETDEV_DOWN but rather the NETDEV_CHANGE event
      which does not flush the routes inserted prior.
      When the link is brought up
          ip link set dev eth4.105 up
      the prefix route is added in the VRF table, but does not remove
      the route from the main table.
      Fix by handling the NETDEV_CHANGEUPPER event similar what was implemented
      for IPv4 in 7f49e7a3 ("net: Flush local routes when device changes vrf

      net: vrf: Fix dst reference counting · 9ab179d8
      David Ahern authored
      Vivek reported a kernel exception deleting a VRF with an active
      connection through it. The root cause is that the socket has a cached
      reference to a dst that is destroyed. Converting the dst_destroy to
      dst_release and letting proper reference counting kick in does not
      work as the dst has a reference to the device which needs to be released
      as well.
      I talked to Hannes about this at netdev and he pointed out the ipv4 and
      ipv6 dst handling has dst_ifdown for just this scenario. Rather than
      continuing with the reinvented dst wheel in VRF just remove it and
      leverage the ipv4 and ipv6 versions.

      Nametable updates received from the network that cannot be applied
      immediately are placed on a defer queue. This queue is global to the
      TIPC module, which might cause problems when using TIPC in containers.

      we make the queue pernet instead.

      cxgb4: Stop Rx Queues before freeing it up · ebf4dc2b
      Hariprasad Shenai authored
      Stop all Ethernet RX Queues before freeing up various Ingress/Egress
      Queues, etc. We were seeing cases of Ingress Queues not getting serviced
      during the shutdown process leading to Ingress Paths jamming up through
      the chip and blocking the shutdown effort itself.
      One such case involved the Firmware sending a "Flush Token" through the
      ULP-TX -> ULP-RX path for an Ethernet TX Queue being freed in order to
      make sure there weren't any remaining TX Work Requests in the pipeline.
      But the return path was stalled by Ingress Data unable to be delivered to
      the Host because those Ingress Queues were no longer being serviced.

      When using the PTP fpga to hps clock source for the stmmac module
      the appropriate bit in the System Manager FPGA Interface Group register
      needs to be set. This is not set by the bootloader setup  when the
      HPS emac pins are being for this emac module.
      This allows the PTP clock to be sourced from the FPGA and also connects
      the PTP pps and ext trig signals to the stmmac PTP hardware.

      netlink: don't send NETLINK_URELEASE for unbound sockets · e2726020
      Dmitry Ivanov authored
      All existing users of NETLINK_URELEASE use it to clean up resources that
      were previously allocated to a socket via some command. As a result, no
      users require getting this notification for unbound sockets.
      Sending it for unbound sockets, however, is a problem because any user
      (including unprivileged users) can create a socket that uses the same ID
      as an existing socket. Binding this new socket will fail, but if the
      NETLINK_URELEASE notification is generated for such sockets, the users
      thereof will be tricked into thinking the socket that they allocated the
      resources for is closed.
      In the nl80211 case, this will cause destruction of virtual interfaces
      that still belong to an existing hostapd process; this is the case that
      Dmitry noticed. In the NFC case, it will cause a poll abort. In the case
      of netlink log/queue it will cause them to stop reporting events, as if
      Fix this problem by checking that the socket is bound before generating
      the NETLINK_URELEASE notification.

      sctp: avoid refreshing heartbeat timer too often · ba6f5e33
      Marcelo Ricardo Leitner authored
      Currently on high rate SCTP streams the heartbeat timer refresh can
      consume quite a lot of resources as timer updates are costly and it
      contains a random factor, which a) is also costly and b) invalidates
      mod_timer() optimization for not editing a timer to the same value.
      It may even cause the timer to be slightly advanced, for no good reason.
      As suggested by David Laight this patch now removes this timer update
      from hot path by leaving the timer on and re-evaluating upon its
      expiration if the heartbeat is still needed or not, similarly to what is
      done for TCP. If it's not needed anymore the timer is re-scheduled to
      the new timeout, considering the time already elapsed.
      For this, we now record the last tx timestamp per transport, updated in
      the same spots as hb timer was restarted on tx. Also split up
      sctp_transport_reset_timers into sctp_transport_reset_t3_rtx and
      sctp_transport_reset_hb_timer, so we can re-arm T3 without re-arming the
      heartbeat one.
      On loopback with MTU of 65535 and data chunks with 1636, so that we
      have a considerable amount of chunks without stressing system calls,
      netperf -t SCTP_STREAM -l 30, perf looked like this before:

        sd being overly chatty on revalidation (causing excess log increases).
        A VPD issue which could crash USB devices because they seem very

           cause the kernel to panic() (Shanker Donthineni).

           wakeup settings reconfiguration from sysfs (Grygorii Strashko).
         - Runtime PM documentation update to make it describe what needs to
           be done during device removal more precisely (Krzysztof Kozlowski).
