        good base to start with for basing a for-next branch on -rc2.

      When mapping a directory, we want the MAY_WRITE permissions to reflect
      whether or not we have permission to modify, add and delete the directory
      entries. MAY_EXEC must map to lookup permissions.

      net/sunrpc/xprt_sock: fix regression in connection error reporting. · 3ffbc1d6
      NeilBrown 提交于
      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 提交于
      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 提交于
      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.

      net: bonding: Fix transmit load balancing in balance-alb mode · cbf5ecb3
      Kosuke Tatsukawa 提交于
      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.
      
      Fixes: 8b426dc5 ("bonding: remove hardcoded value")
