      ipv4: ipmr: fix NULL pointer deref during unres queue destruction · 8de53dfb
      Patrick McHardy 提交于
      Fix an oversight in ipmr_destroy_unres() - the net pointer is
      unconditionally initialized to NULL, resulting in a NULL pointer
      dereference later on.
      
      Fix by adding a net pointer to struct mr_table and using it in
      ipmr_destroy_unres().

      ipv4: ipmr: fix invalid cache resolving when adding a non-matching entry · b0ebb739
      Patrick McHardy 提交于
      The patch to convert struct mfc_cache to list_heads (ipv4: ipmr: convert
      struct mfc_cache to struct list_head) introduced a bug when adding new
      cache entries that don't match any unresolved entries.
      
      The unres queue is searched for a matching entry, which is then resolved.
      When no matching entry is present, the iterator points to the head of the
      list, but is treated as a matching entry. Use a seperate variable to
      indicate that a matching entry was found.

      net: netif_rx() must disable preemption · b0e28f1e
      Eric Dumazet 提交于
      Eric Paris reported netif_rx() is calling smp_processor_id() from
      preemptible context, in particular when caller is
      ip_dev_loopback_xmit().
      
      RPS commit added this smp_processor_id() call, this patch makes sure
      preemption is disabled. rps_get_cpus() wants rcu_read_lock() anyway, we
      can dot it a bit earlier.

      ixgbe: fix bug with vlan strip in promsic mode · 5f6c0181
      Jesse Brandeburg 提交于
      The ixgbe driver was setting up 82598 hardware correctly, so that
      when promiscuous mode was enabled hardware stripping was turned
      off.  But on 82599 the logic to disable/enable hardware stripping
      is different, and the code was not updated correctly when the
      hardware vlan stripping was enabled as default.
      
      This change comprises the creation of two new helper functions
      and calling them from the right locations to disable and enable
      hardware stripping of vlan tags at appropriate times.

      ath9k-htc: fix lockdep warning and kernel warning after unplugging ar9271 usb device · f8e1d080
      Ming Lei 提交于
      This patch fixes two warnings below after unplugging ar9271 usb device:
      	-one is a kernel warning[1]
      	-another is a lockdep warning[2]
      
      The root reason is that __skb_queue_purge can't be executed in hardirq
      context, so the patch forks ath9k_skb_queue_purge(ath9k version of _skb_queue_purge),
      which frees skb with dev_kfree_skb_any which can be run in hardirq
      context safely, then prevent the lockdep warning and kernel warning after
      unplugging ar9271 usb device.

      ath9k-htc:respect usb buffer cacheline alignment in reg out path · 0fa35a58
      Ming Lei 提交于
      In ath9k-htc register out path, ath9k-htc will pass skb->data into
      usb hcd and usb hcd will do dma mapping and unmapping to the buffer
      pointed by skb->data, so we should pass a cache-line aligned address.
      
      This patch replace __dev_alloc_skb with alloc_skb to make skb->data
      pointed to a cacheline aligned address simply since ath9k-htc does not
      skb_push on the skb and pass it to mac80211, also use kfree_skb to free
      the skb allocated by alloc_skb(we can use kfree_skb safely in hardirq
      context since skb->destructor is NULL always in the path).

      ath5k: treat RXORN as non-fatal · 87d77c4e
      Bruno Randolf 提交于
      We get RXORN interrupts when all receive buffers are full. This is not
      necessarily a fatal situation. It can also happen when the bus is busy or the
      CPU is not fast enough to process all frames.
      
      Older chipsets apparently need a reset to come out of this situration, but on
      newer chips we can treat RXORN like RX, as going thru a full reset does more
      harm than good, there.
      
      The exact chip revisions which need a reset are unknown - this guess
      AR5K_SREV_AR5212 ("venice") is copied from the HAL.
      
      Inspired by openwrt 413-rxorn.patch:
      "treat rxorn like rx, reset after rxorn seems to do more harm than good"

      ath5k: Use high bitrates for ACK/CTS · 0edc9a67
      Bruno Randolf 提交于
      There was a confusion in the usage of the bits AR5K_STA_ID1_ACKCTS_6MB and
      AR5K_STA_ID1_BASE_RATE_11B. If they are set (1), we will get lower bitrates for
      ACK and CTS. Therefore ath5k_hw_set_ack_bitrate_high(ah, false) actually
      resulted in high bitrates, which i think is what we want anyways. Cleared the
      confusion and added some documentation.
