      net: bcmgenet: core changes for supporting multiple Rx queues · 8ac467e8
      Petri Gynther authored
      1. Add struct bcmgenet_rx_ring to hold all necessary information
         for a single Rx queue.
      2. Add bcmgenet_init_rx_queues() to initialize all Rx queues.
      3. Modify bcmgenet_init_rx_ring() to initialize a single Rx queue.
      4. Modify Rx interrupt path code to use per-queue data.
      5. Modify bcmgenet_rx_refill() to use RxCB->bd_addr.

      Pull seq-buf/ftrace fixes from Steven Rostedt:
       "This includes fixes for seq_buf_bprintf() truncation issue.  It also
        contains fixes to ftrace when /proc/sys/kernel/ftrace_enabled and
        function tracing are started.  Doing the following causes some issues:
      
          # echo 0 > /proc/sys/kernel/ftrace_enabled
          # echo function_graph > /sys/kernel/debug/tracing/current_tracer
          # echo 1 > /proc/sys/kernel/ftrace_enabled
          # echo nop > /sys/kernel/debug/tracing/current_tracer
          # echo function_graph > /sys/kernel/debug/tracing/current_tracer
      
        As well as with function tracing too.  Pratyush Anand first reported
        this issue to me and supplied a patch.  When I tested this on my x86
        test box, it caused thousands of backtraces and warnings to appear in
        dmesg, which also caused a denial of service (a warning for every
        function that was listed).  I applied Pratyush's patch but it did not
        fix the issue for me.  I looked into it and found a slight problem
        with trampoline accounting.  I fixed it and sent Pratyush a patch, but
        he said that it did not fix the issue for him.
      
        I later learned tha Pratyush was using an ARM64 server, and when I
        tested on my ARM board, I was able to reproduce the same issue as
        Pratyush.  After applying his patch, it fixed the problem.  The above
        test uncovered two different bugs, one in x86 and one in ARM and
        ARM64.  As this looked like it would affect PowerPC, I tested it on my
        PPC64 box.  It too broke, but neither the patch that fixed ARM or x86
        fixed this box (the changes were all in generic code!).  The above
        test, uncovered two more bugs that affected PowerPC.  Again, the
        changes were only done to generic code.  It's the way the arch code
        expected things to be done that was different between the archs.  Some
        where more sensitive than others.
      
        The rest of this series fixes the PPC bugs as well"

      Pull networking fixes from David Miller:
      
       1) nft_compat accidently truncates ethernet protocol to 8-bits, from
          Arturo Borrero.
      
       2) Memory leak in ip_vs_proc_conn(), from Julian Anastasov.
      
       3) Don't allow the space required for nftables rules to exceed the
          maximum value representable in the dlen field.  From Patrick
          McHardy.
      
       4) bcm63xx_enet can accidently leave interrupts permanently disabled
          due to errors in the NAPI polling exit logic.  Fix from Nicolas
          Schichan.
      
       5) Fix OOPSes triggerable by the ping protocol module, due to missing
          address family validations etc.  From Lorenzo Colitti.
      
       6) Don't use RCU locking in sleepable context in team driver, from Jiri
          Pirko.
      
       7) xen-netback miscalculates statistic offset pointers when reporting
          the stats to userspace.  From David Vrabel.
      
       8) Fix a leak of up to 256 pages per VIF destroy in xen-netaback, also
          from David Vrabel.
      
       9) ip_check_defrag() cannot assume that skb_network_offset(),
          particularly when it is used by the AF_PACKET fanout defrag code.
          From Alexander Drozdov.
      
      10) gianfar driver doesn't query OF node names properly when trying to
          determine the number of hw queues available.  Fix it to explicitly
          check for OF nodes named queue-group.  From Tobias Waldekranz.
      
      11) MID field in macb driver should be 12 bits, not 16.  From Punnaiah
          Choudary Kalluri.
      
      12) Fix unintentional regression in traceroute due to timestamp socket
          option changes.  Empty ICMP payloads should be allowed in
          non-timestamp cases.  From Willem de Bruijn.
      
      13) When devices are unregistered, we have to get rid of AF_PACKET
          multicast list entries that point to it via ifindex.  Fix from
          Francesco Ruggeri.

      Pull workqueue fix from Tejun Heo:
       "One fix patch for a subtle livelock condition which can happen on
        PREEMPT_NONE kernels involving two racing cancel_work calls.  Whoever
        comes in the second has to wait for the previous one to finish.  This
        was implemented by making the later one block for the same condition
        that the former would be (work item completion) and then loop and
        retest; unfortunately, depending on the wake up order, the later one
        could lock out the former one to finish by busy looping on the cpu.
      
        This is fixed by implementing explicit wait mechanism.  Work item
        might not belong anywhere at this point and there's remote possibility
        of thundering herd problem.  I originally tried to use bit_waitqueue
        but it didn't work for static work items on modules.  It's currently
        using single wait queue with filtering wake up function and exclusive
        wakeup.  If this ever becomes a problem, which is not very likely, we
        can try to figure out a way to piggy back on bit_waitqueue"
