      net: stmmac: dwmac-oxnas: fix fixed-link-phydev leaks · 6b4c212b
      Johan Hovold 提交于
      Make sure to deregister and free any fixed-link phy registered during
      probe on probe errors and on driver unbind by calling the new glue
      helper function.
      
      For driver unbind, use the generic stmmac-platform remove implementation
      and add an exit callback to disable the clock.

      5.2. Action on Reception of a Query
      
       When a system receives a Query, it does not respond immediately.
       Instead, it delays its response by a random amount of time, bounded
       by the Max Resp Time value derived from the Max Resp Code in the
       received Query message.  A system may receive a variety of Queries on
       different interfaces and of different kinds (e.g., General Queries,
       Group-Specific Queries, and Group-and-Source-Specific Queries), each
       of which may require its own delayed response.
      
       Before scheduling a response to a Query, the system must first
       consider previously scheduled pending responses and in many cases
       schedule a combined response.  Therefore, the system must be able to
       maintain the following state:
      
       o A timer per interface for scheduling responses to General Queries.
      
       o A per-group and interface timer for scheduling responses to Group-
         Specific and Group-and-Source-Specific Queries.
      
       o A per-group and interface list of sources to be reported in the
         response to a Group-and-Source-Specific Query.
      
       When a new Query with the Router-Alert option arrives on an
       interface, provided the system has state to report, a delay for a
       response is randomly selected in the range (0, [Max Resp Time]) where
       Max Resp Time is derived from Max Resp Code in the received Query
       message.  The following rules are then used to determine if a Report
       needs to be scheduled and the type of Report to schedule.  The rules
       are considered in order and only the first matching rule is applied.
      
       1. If there is a pending response to a previous General Query
          scheduled sooner than the selected delay, no additional response
          needs to be scheduled.
      
       2. If the received Query is a General Query, the interface timer is
          used to schedule a response to the General Query after the
          selected delay.  Any previously pending response to a General
          Query is canceled.
      --8<--
      
      Currently the timer is rearmed with new random expiration time for
      every incoming query regardless of possibly already pending report.
      Which is not aligned with the above RFE.
      It also might happen that higher rate of incoming queries can
      postpone the report after the expiration time of the first query
      causing group membership loss.
      
      Now the per interface general query timer is rearmed only
      when there is no pending report already scheduled on that interface or
      the newly selected expiration time is before the already pending
      scheduled report.

      flow_dissector: Update pptp handling to avoid null pointer deref. · d0af6834
      Ian Kumlien 提交于
      __skb_flow_dissect can be called with a skb or a data packet, either
      can be NULL. All calls seems to have been moved to __skb_header_pointer
      except the pptp handling which is still calling skb_header_pointer.
      
      skb_header_pointer will use skb->data and thus:
