      virtio-net: batch stats updating · 61845d20
      Jason Wang authored
      We already have counters for sent/recv packets and sent/recv bytes.
      Doing a batched update to reduce the number of
      u64_stats_update_begin/end().
      
      Take care not to bother with stats update when called
      speculatively.

      mlx4: fix potential divide by 0 in mlx4_en_auto_moderation() · f5a57723
      Eric Dumazet authored
      1) In the case where rate == priv->pkt_rate_low == priv->pkt_rate_high,
      mlx4_en_auto_moderation() does a divide by zero.
      
      2) We want to properly change the moderation parameters if rx_frames
      was changed (like in ethtool -C eth0 rx-frames 16)

      On the kernel side, sockaddr_storage is #define'd to
      __kernel_sockaddr_storage.  Replacing struct sockaddr_storage with
      struct __kernel_sockaddr_storage defined by <linux/socket.h> fixes
      the following linux/rds.h userspace compilation error:

      ibmvnic: Make CRQ interrupt tasklet wait for all capabilities crqs · 249168ad
      Thomas Falcon authored
      After sending device capability queries and requests to the vNIC Server,
      an interrupt is triggered and the responses are written to the driver's
      CRQ response buffer. Since the interrupt can be triggered before all
      responses are written and visible to the partition, there is a danger
      that the interrupt handler or tasklet can terminate before all responses
      are read, resulting in a failure to initialize the device.
      
      To avoid this scenario, when capability commands are sent, we set
      a flag that will be checked in the following interrupt tasklet that
      will handle the capability responses from the server. Once all
      responses have been handled, the flag is disabled; and the tasklet
      is allowed to terminate.

      Create a tasklet to process queued commands or messages received from
      firmware instead of processing them in the interrupt handler. Note that
      this handler does not process network traffic, but communications related
      to resource allocation and device settings.

      printk: use rcuidle console tracepoint · fc98c3c8
      Sergey Senozhatsky authored
      Use rcuidle console tracepoint because, apparently, it may be issued
      from an idle CPU:
      
        hw-breakpoint: Failed to enable monitor mode on CPU 0.
        hw-breakpoint: CPU 0 failed to disable vector catch
      
        ===============================
        [ ERR: suspicious RCU usage.  ]
        4.10.0-rc8-next-20170215+ #119 Not tainted
        -------------------------------
        ./include/trace/events/printk.h:32 suspicious rcu_dereference_check() usage!
      
        other info that might help us debug this:
      
        RCU used illegally from idle CPU!
        rcu_scheduler_active = 2, debug_locks = 0
        RCU used illegally from extended quiescent state!
        2 locks held by swapper/0/0:

         #1:  (console_lock){+.+.+.}, at: [<c01ab350>] vprintk_emit+0x264/0x474
      
        stack backtrace:
        CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.10.0-rc8-next-20170215+ #119

      This RCU warning, however, is suppressed by lockdep_off() in printk().
      lockdep_off() increments the ->lockdep_recursion counter and thus
      disables RCU_LOCKDEP_WARN() and debug_lockdep_rcu_enabled(), which want
      lockdep to be enabled "current->lockdep_recursion == 0".
