      net: allow macvlans to move to net namespace · 0d0162e7
      Francesco Ruggeri 提交于
      I cannot move a macvlan interface created on top of a bonding interface
      to a different namespace:
      
      % ip netns add dummy0
      % ip link add link bond0 mac0 type macvlan
      % ip link set mac0 netns dummy0
      RTNETLINK answers: Invalid argument
      %
      
      The problem seems to be that commit f9399814 ("bonding: Don't allow
      bond devices to change network namespaces.") sets NETIF_F_NETNS_LOCAL
      on bonding interfaces, and commit 797f87f8 ("macvlan: fix netdev
      feature propagation from lower device") causes macvlan interfaces
      to inherit its features from the lower device.
      
      NETIF_F_NETNS_LOCAL should not be inherited from the lower device
      by a macvlan.
      Patch tested on 3.16.

      3c59x: Fix bad offset spec in skb_frag_dma_map · 8400dd02
      Neil Horman 提交于
      Recently aded the use of skb_frag_dma_map to 3c59x, but didn't realize it
      automatically included the frag_offset internally, as well as provided an option
      to specify an extra offset in the parameter list.  We need to specify an offset
      of 0 in the parameter list to avoid skb corruption that results in lost
      connections.

      3c59x: Add dma error checking and recovery · 6f2b6a30
      Neil Horman 提交于
      Noted that 3c59x has no checks on transmit for failed DMA mappings, and no
      ability to unmap fragments when a single map fails in the middle of a transmit.
      This patch provides error checking to ensure that dma mappings work properly,
      and unrolls an skb mapping if a fragmented skb transmission has a mapping
      failure to prevent leaks.

      bonding: fix div by zero while enslaving and transmitting · 9a72c2da
      Nikolay Aleksandrov 提交于
      The problem is that the slave is first linked and slave_cnt is
      incremented afterwards leading to a div by zero in the modes that use it
      as a modulus. What happens is that in bond_start_xmit()
      bond_has_slaves() is used to evaluate further transmission and it becomes
      true after the slave is linked in, but when slave_cnt is used in the xmit
      path it is still 0, so fetch it once and transmit based on that. Since
      it is used only in round-robin and XOR modes, the fix is only for them.
      Thanks to Eric Dumazet for pointing out the fault in my first try to fix
      this.
