      Pull more rdma fixes from Doug Ledford:
       "As per my previous pull request, there were two drivers that each had
        a rather large number of legitimate fixes still to be sent.
      
        As it turned out, I also missed a reasonably large set of fixes from
        one person across the stack that are all important fixes. All in all,
        the bnxt_re, i40iw, and Dan Carpenter are 3/4 to 2/3rds of this pull
        request.
      
        There were some other random fixes that I didn't send in the last pull
        request that I added to this one. This catches the rdma stack up to
        the fixes from up to about the beginning of this week. Any more fixes
        I'll wait and batch up later in the -rc cycle. This will give us a
        good base to start with for basing a for-next branch on -rc2.
      
        Summary:
      
         - i40iw fixes
      
         - bnxt_re fixes

      net/sunrpc/xprt_sock: fix regression in connection error reporting. · 3ffbc1d6
      NeilBrown authored
      Commit 3d476263 ("tcp: remove poll() flakes when receiving
      RST") in v4.12 changed the order in which ->sk_state_change()
      and ->sk_error_report() are called when a socket is shut
      down - sk_state_change() is now called first.
      
      This causes xs_tcp_state_change() -> xs_sock_mark_closed() ->
      xprt_disconnect_done() to wake all pending tasked with -EAGAIN.
      When the ->sk_error_report() callback arrives, it is too late to
      pass the error on, and it is lost.
      
      As easy way to demonstrate the problem caused is to try to start
      rpc.nfsd while rcpbind isn't running.
      nfsd will attempt a tcp connection to rpcbind.  A ECONNREFUSED
      error is returned, but sunrpc code loses the error and keeps
      retrying.  If it saw the ECONNREFUSED, it would abort.
      
      To fix this, handle the sk->sk_err in the TCP_CLOSE branch of
      xs_tcp_state_change().

      perf/x86/intel: Add proper condition to run sched_task callbacks · df6c3db8
      Jiri Olsa authored
      
      
      We have 2 functions using the same sched_task callback:
      
        - PEBS drain for free running counters
        - LBR save/store
      
      Both of them are called from intel_pmu_sched_task() and
      either of them can be unwillingly triggered when the
      other one is configured to run.
      
      Let's say there's PEBS drain configured in sched_task
      callback for the event, but in the callback itself
      (intel_pmu_sched_task()) we will also run the code for
      LBR save/restore, which we did not ask for, but the
      code in intel_pmu_sched_task() does not check for that.
      
      This can lead to extra cycles in some perf monitoring,
      like when we monitor PEBS event without LBR data.
      
        # perf record --no-timestamp -c 10000 -e cycles:p ./perf bench sched pipe -l 1000000
      
        (We need PEBS, non freq/non timestamp event to enable
         the sched_task callback)
      
      The perf stat of cycles and msr:write_msr for above
      command before the change:
        ...
        Performance counter stats for './perf record --no-timestamp -c 10000 -e cycles:p \
                                       ./perf bench sched pipe -l 1000000' (5 runs):
      
          18,519,557,441      cycles:k
              91,195,527      msr:write_msr
      
            29.334476406 seconds time elapsed
      
      And after the change:
        ...
        Performance counter stats for './perf record --no-timestamp -c 10000 -e cycles:p \
                                       ./perf bench sched pipe -l 1000000' (5 runs):
      
          18,704,973,540      cycles:k
              27,184,720      msr:write_msr
      
            16.977875900 seconds time elapsed
      
      There's no affect on cycles:k because the sched_task happens
      with events switched off, however the msr:write_msr tracepoint
      counter together with almost 50% of time speedup show the
      improvement.
      
      Monitoring LBR event and having extra PEBS drain processing
      in sched_task callback showed just a little speedup, because
      the drain function does not do much extra work in case there
      is no PEBS data.
      
      Adding conditions to recognize the configured work that needs
      to be done in the x86_pmu's sched_task callback.

      perf/core: Fix locking for children siblings group read · 2aeb1883
      Jiri Olsa authored
      We're missing ctx lock when iterating children siblings
      within the perf_read path for group reading. Following
      race and crash can happen:
      
      User space doing read syscall on event group leader:
      
      T1:
        perf_read
          lock event->ctx->mutex
          perf_read_group
            lock leader->child_mutex
            __perf_read_group_add(child)
              list_for_each_entry(sub, &leader->sibling_list, group_entry)
      
      ---->   sub might be invalid at this point, because it could
              get removed via perf_event_exit_task_context in T2
      
      Child exiting and cleaning up its events:
      
      T2:
        perf_event_exit_task_context
          lock ctx->mutex
          list_for_each_entry_safe(child_event, next, &child_ctx->event_list,...
            perf_event_exit_event(child)
              lock ctx->lock
              perf_group_detach(child)
              unlock ctx->lock
      
      ---->   child is removed from sibling_list without any sync
              with T1 path above
      
              ...
              free_event(child)
      
      Before the child is removed from the leader's child_list,
      (and thus is omitted from perf_read_group processing), we
      need to ensure that perf_read_group touches child's
      siblings under its ctx->lock.
      
      Peter further notes:
      
      | One additional note; this bug got exposed by commit:
      |
      |   ba5213ae
      
       ("perf/core: Correct event creation with PERF_FORMAT_GROUP")

      net: bonding: Fix transmit load balancing in balance-alb mode · cbf5ecb3
      Kosuke Tatsukawa authored
      balance-alb mode used to have transmit dynamic load balancing feature
      enabled by default.  However, transmit dynamic load balancing no longer
      works in balance-alb after commit 8b426dc5 ("bonding: remove
      hardcoded value").
      
      Both balance-tlb and balance-alb use the function bond_do_alb_xmit() to
      send packets.  This function uses the parameter tlb_dynamic_lb.
      tlb_dynamic_lb used to have the default value of 1 for balance-alb, but
      now the value is set to 0 except in balance-tlb.
      
      Re-enable transmit dyanmic load balancing by initializing tlb_dynamic_lb
      for balance-alb similar to balance-tlb.

      rds: Make sure updates to cp_send_gen can be observed · e623a48e
      Håkon Bugge authored
      
      
      cp->cp_send_gen is treated as a normal variable, although it may be
      used by different threads.
      
      This is fixed by using {READ,WRITE}_ONCE when it is incremented and
      READ_ONCE when it is read outside the {acquire,release}_in_xmit
      protection.
      
      Normative reference from the Linux-Kernel Memory Model:
      
          Loads from and stores to shared (but non-atomic) variables should
          be protected with the READ_ONCE(), WRITE_ONCE(), and
          ACCESS_ONCE().
      
      Clause 5.1.2.4/25 in the C standard is also relevant.

      net: ethernet: ti: cpsw: Push the request_irq function to the end of probe · 070f9c65

      Push the request_irq function to the end of probe so as
      to ensure all the required fields are populated in the event
      of an ISR getting executed right after requesting the irq.
      
      Currently while loading the crash kernel a crash was seen as
      soon as devm_request_threaded_irq was called. This was due to
      n->poll being NULL which is called as part of net_rx_action
      function.

      ipv4: initialize fib_trie prior to register_netdev_notifier call. · 8799a221
      Mahesh Bandewar authored
      Net stack initialization currently initializes fib-trie after the
      first call to netdevice_notifier() call. In fact fib_trie initialization
      needs to happen before first rtnl_register(). It does not cause any problem
      since there are no devices UP at this moment, but trying to bring 'lo'
      UP at initialization would make this assumption wrong and exposes the issue.

      rtnetlink: allocate more memory for dev_set_mac_address() · 153711f9
      WANG Cong authored
      
      
      virtnet_set_mac_address() interprets mac address as struct
      sockaddr, but upper layer only allocates dev->addr_len
      which is ETH_ALEN + sizeof(sa_family_t) in this case.
      
      We lack a unified definition for mac address, so just fix
      the upper layer, this also allows drivers to interpret it
      to struct sockaddr freely.
