      tipc: resolve connection flow control compatibility problem · 6998cc6e
      Jon Paul Maloy authored
      In commit 10724cc7 ("tipc: redesign connection-level flow control")
      we replaced the previous message based flow control with one based on
      1k blocks. In order to ensure backwards compatibility the mechanism
      falls back to using message as base unit when it senses that the peer
      doesn't support the new algorithm. The default flow control window,
      i.e., how many units can be sent before the sender blocks and waits
      for an acknowledge (aka advertisement) is 512. This was tested against
      the previous version, which uses an acknowledge frequency of on ack per
      256 received message, and found to work fine.
      
      However, we missed the fact that versions older than Linux 3.15 use an
      acknowledge frequency of 512, which is exactly the limit where a 4.6+
      sender will stop and wait for acknowledge. This would also work fine if
      it weren't for the fact that if the first sent message on a 4.6+ server
      side is an empty SYNACK, this one is also is counted as a sent message,
      while it is not counted as a received message on a legacy 3.15-receiver.
      This leads to the sender always being one step ahead of the receiver, a
      scenario causing the sender to block after 512 sent messages, while the
      receiver only has registered 511 read messages. Hence, the legacy
      receiver is not trigged to send an acknowledge, with a permanently
      blocked sender as result.
      
      We solve this deadlock by simply allowing the sender to send one more
      message before it blocks, i.e., by a making minimal change to the
      condition used for determining connection congestion.

      mvpp2: use correct size for memset · e8f967c3
      Arnd Bergmann authored
      gcc-7 detects a short memset in mvpp2, introduced in the original
      merge of the driver:
      
      drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_cls_init':
      drivers/net/ethernet/marvell/mvpp2.c:3296:2: error: 'memset' used with length equal to number of elements without multiplication by element size [-Werror=memset-elt-size]
      
      The result seems to be that we write uninitialized data into the
      flow table registers, although we did not get any warning about
      that uninitialized data usage.
      
      Using sizeof() lets us initialize then entire array instead.

      tipc: improve sanity check for received domain records · d876a4d2
      Jon Paul Maloy authored
      In commit 35c55c98 ("tipc: add neighbor monitoring framework") we
      added a data area to the link monitor STATE messages under the
      assumption that previous versions did not use any such data area.
      
      For versions older than Linux 4.3 this assumption is not correct. In
      those version, all STATE messages sent out from a node inadvertently
      contain a 16 byte data area containing a string; -a leftover from
      previous RESET messages which were using this during the setup phase.
      This string serves no purpose in STATE messages, and should no be there.
      
      Unfortunately, this data area is delivered to the link monitor
      framework, where a sanity check catches that it is not a correct domain
      record, and drops it. It also issues a rate limited warning about the
      event.
      
      Since such events occur much more frequently than anticipated, we now
      choose to remove the warning in order to not fill the kernel log with
      useless contents. We also make the sanity check stricter, to further
      reduce the risk that such data is inavertently admitted.

      tipc: fix compatibility bug in link monitoring · f7967556
      Jon Paul Maloy authored
      commit 81729810 ("tipc: fix link priority propagation") introduced a
      compatibility problem between TIPC versions newer than Linux 4.6 and
      those older than Linux 4.4. In versions later than 4.4, link STATE
      messages only contain a non-zero link priority value when the sender
      wants the receiver to change its priority. This has the effect that the
      receiver resets itself in order to apply the new priority. This works
      well, and is consistent with the said commit.
      
      However, in versions older than 4.4 a valid link priority is present in
      all sent link STATE messages, leading to cyclic link establishment and
      reset on the 4.6+ node.
      
      We fix this by adding a test that the received value should not only
      be valid, but also differ from the current value in order to cause the
      receiving link endpoint to reset.

      The mvneta driver advertises it supports IFF_UNICAST_FLT. However, it
      actually does not. The hardware probably does support it, but there is
      no code to configure the filter. As a quick and simple fix, remove the
      flag. This will cause the core to fall back to promiscuous mode.

      Linus Torvalds authored
      Pull parisc fixes from Helge Deller:
       "On parisc we were still seeing occasional random segmentation faults
        and memory corruption on SMP machines. Dave Anglin then looked again
        at the TLB related code and found two issues in the PCI DMA and
        generic TLB flush functions.
      
        Then, in our startup code we had some timing of the cache and TLB
        functions to calculate a threshold when to use a complete TLB/cache
        flush or just to flush a specific range. This code produced a race
        with newly started CPUs and thus lead to occasional kernel crashes
        (due to stale TLB/cache entries). The patch by Dave fixes this issue
        by flushing the local caches before starting secondary CPUs and by
        removing the race.
      
        The last problem fixed by this series is that we quite often suffered
        from hung tasks and self-detected stalls on the CPUs. It was somehow
        clear that this was related to the (in v4.7) newly introduced cr16
        clocksource and the own implementation of sched_clock(). I replaced
        the open-coded sched_clock() function and switched to the generic
        sched_clock() implementation which seems to have fixed this isse as
        well.
      
        All patches have been sucessfully tested on a variety of machines,
        including our debian buildd servers.
      
        All patches (beside the small pr_cont fix) are tagged for stable
