      ip_tunnel: the lack of vti_link_ops' dellink() cause kernel panic · 20ea60ca
      lucien authored
      Now the vti_link_ops do not point the .dellink, for fb tunnel device
      (ip_vti0), the net_device will be removed as the default .dellink is
      unregister_netdevice_queue,but the tunnel still in the tunnel list,
      then if we add a new vti tunnel, in ip_tunnel_find():
      
              hlist_for_each_entry_rcu(t, head, hash_node) {
                      if (local == t->parms.iph.saddr &&
                          remote == t->parms.iph.daddr &&
                          link == t->parms.link &&
      ==>                 type == t->dev->type &&
                          ip_tunnel_key_match(&t->parms, flags, key))
                              break;
              }
      
      the panic will happen, cause dev of ip_tunnel *t is null:

      The issue is that test_and_set_bit() done on adapter->state is being
      performed *after* the netdevice has been freed via free_netdev().
      
      When netdev is being allocated on initialization time, it allocates
      a private area, here struct ixgbe_adapter, that resides after the
      net_device structure. In ixgbe_probe(), the device init routine,
      we set up the adapter after alloc_etherdev_mq() on the private area
      and add a reference for the pci_dev as well via pci_set_drvdata().
      
      Both in the error path of ixgbe_probe(), but also on module unload
      when ixgbe_remove() is being called, commit 41c62843 ("ixgbe:
      Fix rcu warnings induced by LER") accesses adapter after free_netdev().
      The patch stores the result in a bool and thus fixes above oops on my
      side.

      ixgbe: Correctly disable VLAN filter in promiscuous mode · 4556dc59
      Vlad Yasevich authored
      IXGBE adapter seems to require that VLAN filtering be enabled if
      VMDQ or SRIOV are enabled.  When those functions are disabled,
      VLAN filtering may be disabled in promiscuous mode.
      
      Prior to commit a9b8943e ("ixgbe: remove vlan_filter_disable
      and enable functions")
      
      The logic was correct.  However, after the commit the logic
      got reversed and VLAN filtered in now turned on when VMDQ/SRIOV
      is disabled.
      
      This patch changes the condition to enable hw vlan filtered
      when VMDQ or SRIOV is enabled.

      ipv6: Do not treat a GSO_TCPV4 request from UDP tunnel over IPv6 as invalid · b6fef4c6
      Alexander Duyck authored
      This patch adds SKB_GSO_TCPV4 to the list of supported GSO types handled by
      the IPv6 GSO offloads.  Without this change VXLAN tunnels running over IPv6
      do not currently handle IPv4 TCP TSO requests correctly and end up handing
      the non-segmented frame off to the device.
      
      Below is the before and after for a simple netperf TCP_STREAM test between
      two endpoints tunneling IPv4 over a VXLAN tunnel running on IPv6 on top of
      a 1Gb/s network adapter.

       "This is just a one-liner fixing a regression introduced in 3.13 that

        On those machines there are ACPI device objects for some I2C devices
        that can wake up the system from sleep states, but that is done via a
        platform-specific mechanism and the ACPI objects don't contain any

        management with those devices (which happened during the 3.13 cycle),
        their configuration confused the ACPI PM layer that returned error
        codes from suspend callbacks for them causing system suspend to fail.
      
        However, the ACPI PM layer can safely ignore the wakeup setting from a
        device driver if the ACPI object corresponding to the device in
        question doesn't contain wakeup information in which case the driver

         - Loongson 3 is a MIPS64 R2 version but due to erratum we treat is an
           older architecture revision.

           for certain configurations.
         - fix instruction decodig in the jump label code.
         - for certain configurations copy_{from,to}_user destroy the content
           of $3 so that register needs to be marked as clobbed by the calling
           code.
         - Hardware Table Walker fixes.
         - fill the delay slot of the last instruction of memcpy otherwise
           whatever ends up there randomly might have undesirable effects.
         - ensure get_user/__get_user always zero the variable to be read even
           in case of an error"
