      Although vti and vti6 are immune to this problem because they are IFF_NOARP
      interfaces, as Guillaume pointed. There is still no sense to confirm neighbour
      here.

      ip6_gre: do not confirm neighbor when do pmtu update · 675d76ad
      Hangbin Liu authored
      When we do ipv6 gre pmtu update, we will also do neigh confirm currently.
      This will cause the neigh cache be refreshed and set to REACHABLE before
      xmit.
      
      But if the remote mac address changed, e.g. device is deleted and recreated,
      we will not able to notice this and still use the old mac address as the neigh
      cache is REACHABLE.
      
      Fix this by disable neigh confirm when do pmtu update
      
      v5: No change.
      v4: No change.
      v3: Do not remove dst_confirm_neigh, but add a new bool parameter in
          dst_ops.update_pmtu to control whether we should do neighbor confirm.

      net: add bool confirm_neigh parameter for dst_ops.update_pmtu · bd085ef6
      Hangbin Liu authored
      The MTU update code is supposed to be invoked in response to real
      networking events that update the PMTU. In IPv6 PMTU update function
      __ip6_rt_update_pmtu() we called dst_confirm_neigh() to update neighbor
      confirmed time.
      
      But for tunnel code, it will call pmtu before xmit, like:
        - tnl_update_pmtu()
          - skb_dst_update_pmtu()
            - ip6_rt_update_pmtu()
              - __ip6_rt_update_pmtu()
                - dst_confirm_neigh()
      
      If the tunnel remote dst mac address changed and we still do the neigh
      confirm, we will not be able to update neigh cache and ping6 remote
      will failed.
      
      So for this ip_tunnel_xmit() case, _EVEN_ if the MTU is changed, we
      should not be invoking dst_confirm_neigh() as we have no evidence
      of successful two-way communication at this point.
      
      On the other hand it is also important to keep the neigh reachability fresh
      for TCP flows, so we cannot remove this dst_confirm_neigh() call.
      
      To fix the issue, we have to add a new bool parameter for dst_ops.update_pmtu
      to choose whether we should do neigh update or not. I will add the parameter
      in this patch and set all the callers to true to comply with the previous
      way, and fix the tunnel code one by one on later patches.
      
      v5: No change.
      v4: No change.
      v3: Do not remove dst_confirm_neigh, but add a new bool parameter in
          dst_ops.update_pmtu to control whether we should do neighbor confirm.
          Also split the big patch to small ones for each area.
      v2: Remove dst_confirm_neigh in __ip6_rt_update_pmtu.

      ====================
      rxrpc: Fixes
      
      Here are a couple of bugfixes plus a patch that makes one of the bugfixes
      easier:
      
       (1) Move the ping and mutex unlock on a new call from rxrpc_input_packet()
           into rxrpc_new_incoming_call(), which it calls.  This means the
           lock-unlock section is entirely within the latter function.  This
           simplifies patch (2).
      
       (2) Don't take the call->user_mutex at all in the softirq path.  Mutexes
           aren't allowed to be taken or released there and a patch was merged
           that caused a warning to be emitted every time this happened.  Looking
           at the code again, it looks like that taking the mutex isn't actually
           necessary, as the value of call->state will block access to the call.
      
       (3) Fix the incoming call path to check incoming calls earlier to reject
           calls to RPC services for which we don't have a security key of the
           appropriate class.  This avoids an assertion failure if YFS tries
           making a secure call to the kafs cache manager RPC service.

      net: dsa: bcm_sf2: Fix IP fragment location and behavior · 7c3125f0
      Florian Fainelli authored
      The IP fragment is specified through user-defined field as the first
      bit of the first user-defined word. We were previously trying to extract
      it from the user-defined mask which could not possibly work. The ip_frag
      is also supposed to be a boolean, if we do not cast it as such, we risk
      overwriting the next fields in CFP_DATA(6) which would render the rule
      inoperative.

      sctp: fix err handling of stream initialization · 61d5d406
      Marcelo Ricardo Leitner authored
      The fix on 951c6db9 fixed the issued reported there but introduced
      another. When the allocation fails within sctp_stream_init() it is
      okay/necessary to free the genradix. But it is also called when adding
      new streams, from sctp_send_add_streams() and
      sctp_process_strreset_addstrm_in() and in those situations it cannot
      just free the genradix because by then it is a fully operational
      association.
      
      The fix here then is to only free the genradix in sctp_stream_init()
      and on those other call sites  move on with what it already had and let
      the subsequent error handling to handle it.
      
      Tested with the reproducers from this report and the previous one,
      with lksctp-tools and sctp-tests.

      pipe: fix empty pipe check in pipe_write() · 0dd1e377
      Jan Stancek authored
      LTP pipeio_1 test is hanging with v5.5-rc2-385-gb8e382a1,
      with read side observing empty pipe and sleeping and write
      side running out of space and then sleeping as well. In this
      scenario there are 5 writers and 1 reader.
      
      Problem is that after pipe_write() reacquires pipe lock, it
      re-checks for empty pipe with potentially stale 'head' and
      doesn't wake up read side anymore. pipe->tail can advance
      beyond 'head', because there are multiple writers.
      
      Use pipe->head for empty pipe check after reacquiring lock
      to observe current state.
      
      Testing: With patch, LTP pipeio_1 ran successfully in loop for 1 hour.
               Without patch it hanged within a minute.

      MAINTAINERS: remove Radim from KVM maintainers · 19a049f1
      Paolo Bonzini authored
      Radim's kernel.org email is bouncing, which I take as a signal that
      he is not really able to deal with KVM at this time.  Make MAINTAINERS
      match the effective value of KVM's bus factor.

      MAINTAINERS: Orphan KVM for MIPS · 088e11d4
      James Hogan authored
      I haven't been active for 18 months, and don't have the hardware set up
      to test KVM for MIPS, so mark it as orphaned and remove myself as
      maintainer. Hopefully somebody from MIPS can pick this up.
