      qlcnic: Fix bug in Tx completion path · a02bdd42
      Shahed Shaikh authored
      
      
      o Driver is using common tx_clean_lock for all Tx queues. This patch
        adds per queue tx_clean_lock.
      o Driver is not updating sw_consumer while processing Tx completion
        when interface is going down. Fixed in this patch.

      infiniband: make sure the src net is infiniband when create new link · 0d68fc4f
      Hangbin Liu authored
      
      
      When we create a new infiniband link with uninfiniband device, e.g. `ip link
      add link em1 type ipoib pkey 0x8001`. We will get a NULL pointer dereference
      cause other dev like Ethernet don't have struct ib_device.
      
      The code path is:
      rtnl_newlink
        |-- ipoib_new_child_link
              |-- __ipoib_vlan_add
                    |-- ipoib_set_dev_features
                          |-- ib_query_device
      
      Fix this bug by make sure the src net is infiniband when create new link.

      {vxlan, inet6} Mark vxlan_dev flags with VXLAN_F_IPV6 properly · 7bda701e
      fan.du authored
      
      
      Even if user doesn't supply the physical netdev to attach vxlan dev
      to, and at the same time user want to vxlan sit top of IPv6, mark
      vxlan_dev flags with VXLAN_F_IPV6 to create IPv6 based socket.
      Otherwise kernel crashes safely every time spitting below messages,
      
      Steps to reproduce:
      ip link add vxlan0 type vxlan id 42 group ff0e::110
      ip link set vxlan0 up

      cxgb4: allow large buffer size to have page size · 940d9d34
      Thadeu Lima de Souza Cascardo authored
      Since commit 52367a76
      
      
      ("cxgb4/cxgb4vf: Code cleanup to enable T4 Configuration File support"),
      we have failures like this during cxgb4 probe:
      
      cxgb4 0000:01:00.4: bad SGE FL page buffer sizes [65536, 65536]
      cxgb4: probe of 0000:01:00.4 failed with error -22
      
      This happens whenever software parameters are used, without a
      configuration file. That happens when the hardware was already
      initialized (after kexec, or after csiostor is loaded).
      
      It happens that these values are acceptable, rendering fl_pg_order equal
      to 0, which is the case of a hard init when the page size is equal or
      larger than 65536.
      
      Accepting fl_large_pg equal to fl_small_pg solves the issue, and
      shouldn't cause any trouble besides a possible performance reduction
      when smaller pages are used. And that can be fixed by a configuration
      file.

      usbnet: mcs7830: rework link state detection · 8d88bbff
      Octavian Purdila authored
      Even with the quirks in commit dabdaf0c
      
       (mcs7830: Fix link state
      detection) there are still spurious link-down events for some chips
      where the false link-down events count go over a few hundreds.
      
      This patch takes a more conservative approach and only looks at
      link-down events where the link-down state is not combined with other
      states (e.g. half/full speed, pending frames in SRAM or TX status
      information valid). In all other cases we assume the link is up.
      
      Tested on MCS7830CV-DA (USB ID 9710:7830).

      vlan: Fix header ops passthru when doing TX VLAN offload. · 2205369a
      David S. Miller authored
      
      
      When the vlan code detects that the real device can do TX VLAN offloads
      in hardware, it tries to arrange for the real device's header_ops to
      be invoked directly.
      
      But it does so illegally, by simply hooking the real device's
      header_ops up to the VLAN device.
      
      This doesn't work because we will end up invoking a set of header_ops
      routines which expect a device type which matches the real device, but
      will see a VLAN device instead.
      
      Fix this by providing a pass-thru set of header_ops which will arrange
      to pass the proper real device instead.
      
      To facilitate this add a dev_rebuild_header().  There are
      implementations which provide a ->cache and ->create but not a
      ->rebuild (f.e. PLIP).  So we need a helper function just like
      dev_hard_header() to avoid crashes.
      
      Use this helper in the one existing place where the
      header_ops->rebuild was being invoked, the neighbour code.
      
      With lots of help from Florian Westphal.

       "Some holiday bug fixes for 3.13...  There is still one bug I'd like to
        get fixed before 3.13-final.
      
        The vlan code erroneously assignes the header ops of the underlying
        real device to the VLAN device above it when the real device can
        hardware offload VLAN handling.  That's completely bogus because
        header ops are tied to the device type, so they only expect to see a
        'dev' argument compatible with their ops.
      
        The fix is the have the VLAN code use a special set of header ops that
        does the pass-thru correctly, by calling the underlying real device's
        header ops but _also_ passing in the real device instead of the VLAN
        device.

      of/irq: Fix device_node refcount in of_irq_parse_raw() · 2f53a713

      Commit 23616132
      
      , "of/irq: Refactor interrupt-map parsing" changed
      the refcount on the device_node causing an error in of_node_put():
      
      ERROR: Bad of_node_put() on /pci@800000020000000

      This patch adjusts the refcount in the walk of the interrupt tree.
      When a match is found, there is no need to increase the refcount
      on 'out_irq->np' as 'newpar' is already holding a ref. The refcount
      balance between 'ipar' and 'newpar' is maintained in the skiplevel:
      goto label.
      
      This patch also removes the usage of the device_node variable 'old'
      which seems useless after the latest changes.
