      virtio-net: support XDP_REDIRECT · 186b3c99
      Jason Wang authored
      This patch tries to add XDP_REDIRECT for virtio-net. The changes are
      not complex as we could use exist XDP_TX helpers for most of the
      work. The rest is passing the XDP_TX to NAPI handler for implementing
      batching.

      virtio-net: add packet len average only when needed during XDP · 31240345
      Jason Wang authored
      There's no need to add packet len average in the case of XDP_PASS
      since it will be done soon after skb is created.

      bridge: also trigger RTM_NEWLINK when interface is released from bridge · 00ba4cb3
      Vincent Bernat authored
      Currently, when an interface is released from a bridge via
      ioctl(), we get a RTM_DELLINK event through netlink:
      
      Deleted 2: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN
          link/ether 6e:23:c2:54:3a:b3
      
      Userspace has to interpret that as a removal from the bridge, not as a
      complete removal of the interface. When an bridged interface is
      completely removed, we get two events:
      
      Deleted 2: dummy0: <BROADCAST,NOARP> mtu 1500 master bridge0 state DOWN
          link/ether 6e:23:c2:54:3a:b3
      Deleted 2: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default
          link/ether 6e:23:c2:54:3a:b3 brd ff:ff:ff:ff:ff:ff
      
      In constrast, when an interface is released from a bond, we get a
      RTM_NEWLINK with only the new characteristics (no master):
      
      3: dummy1: <BROADCAST,NOARP,SLAVE,UP,LOWER_UP> mtu 1500 qdisc noqueue master bond0 state UNKNOWN group default
          link/ether ae:dc:7a:8c:9a:3c brd ff:ff:ff:ff:ff:ff
      3: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default
          link/ether ae:dc:7a:8c:9a:3c brd ff:ff:ff:ff:ff:ff
      4: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
          link/ether ae:dc:7a:8c:9a:3c brd ff:ff:ff:ff:ff:ff
      3: dummy1: <BROADCAST,NOARP> mtu 1500 qdisc noqueue state DOWN group default
          link/ether ae:dc:7a:8c:9a:3c brd ff:ff:ff:ff:ff:ff
      3: dummy1: <BROADCAST,NOARP> mtu 1500 qdisc noqueue state DOWN group default
          link/ether ca:c8:7b:66:f8:25 brd ff:ff:ff:ff:ff:ff
      4: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
          link/ether ae:dc:7a:8c:9a:3c brd ff:ff:ff:ff:ff:ff
      
      Userland may be confused by the fact we say a link is deleted while
      its characteristics are only modified. A first solution would have
      been to turn the RTM_DELLINK event in del_nbp() into a RTM_NEWLINK
      event. However, maybe some piece of userland is relying on this
      RTM_DELLINK to detect when a bridged interface is released. Instead,
      we also emit a RTM_NEWLINK event once the interface is
      released (without master info).
      
      Deleted 2: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN
          link/ether 8a:bb:e7:94:b1:f8
      2: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default
          link/ether 8a:bb:e7:94:b1:f8 brd ff:ff:ff:ff:ff:ff
      
      This is done only when using ioctl(). When using Netlink, such an
      event is already automatically emitted in do_setlink().

      ipv6: Use ipv6_authlen for len in ipv6_skip_exthdr · d4e1b299
      Xiang Gao authored
      In ipv6_skip_exthdr, the lengh of AH header is computed manually
      as (hp->hdrlen+2)<<2. However, in include/linux/ipv6.h, a macro
      named ipv6_authlen is already defined for exactly the same job. This
      commit replaces the manual computation code with the macro.
