* batman-adv: Convert batadv_neigh_node to krefSven Eckelmann2016-02-104-17/+20
| | | | | | | | | | batman-adv uses a self-written reference implementation which is just based on atomic_t.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Willem de Bruijn says: ==================== packet: tpacket gso and csum offload Extend PACKET_VNET_HDR socket option support to packet sockets with memory mapped rings. Patches 2 and 4 add support to tpacket_rcv and tpacket_snd. Patch 1 prepares for this by moving the relevant virtio_net_hdr logic out of packet_snd and packet_rcv into helper functions. GSO transmission requires all headers in the skb linear section. Patch 3 moves parsing of tx_ring slot headers before skb allocation to enable allocation with sufficient linear size. Changes v1->v2: - fix bounds checks: - subtract sizeof(vnet_hdr) before comparing tp_len to size_max - compare tp_len to size_max also with GSO, just do not truncate to MTU ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| * packet: tpacket_snd gso and checksum offloadWillem de Bruijn2016-02-091-16/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support socket option PACKET_VNET_HDR together with PACKET_TX_RING. When enabled, a struct virtio_net_hdr is expected to precede the data in the ring. The vnet option must be set before the ring is created. The implementation reuses the existing skb_copy_bits code that is used when dev->hard_header_len is non-zero. Move this ll_header check to before the skb alloc and combine it with a test for vnet_hdr->hdr_len. Allocate and copy the max of the two.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | GSO packet headers must be stored in the linear skb segment. Move tpacket header parsing before sock_alloc_send_skb. The GSO follow-on patch will later increase the skb linear argument to sock_alloc_send_skb if needed for large packets. The header parsing code does not require an allocated skb, so is safe to move. Later pass to tpacket_fill_skb the computed data start and length. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* bonding: 3ad: apply ad_actor settings changes immediatelyNikolay Aleksandrov2016-02-093-3/+42
| | | | | | | | | | | | | | | | Currently the bonding allows to set ad_actor_system and prio while the bond device is down, but these are actually applied only if there aren't any slaves yet (applied to bond device when first slave shows up, and to slaves at 3ad bind time). After this patch changes are applied immediately and the new values can be used/seen after the bond's upped so it's not necessary anymore to release all and enslave again to see the changes.

Most of these apply per socket and have global defaults so should be safe and I don't expect any breakages. Having those per net-namespace is useful when multiple containers are hosted and it is required to tune the tcp settings for each independently of the host node.
