batman-adv uses a self-written reference implementation which is just based on atomic_t. This is less obvious when reading the code than kref and therefore increases the change that the reference counting will be missed. Signed-off-by:

To allow future use of the window protected function with different maximum sequence numbers, add a parameter to set this value which was previously hardcoded. Another parameter added for future use is a flag to return whether the protection window has started. While at it, also fix the kerneldoc. Signed-off-by:

Sergei Shtylyov says: ==================== Factor out register bit twiddling in the Renesas Ethernet drivers Here's a set of 2 patches against DaveM's 'net-next.git' repo. We factor out the often repeated pattern of reading a register, AND'ing and/or OR'ing some bits, and then writing the value back.

The driver has often repeated pattern of reading a register, AND'ing and/or OR'ing some bits and writing the value back. Factor the pattern out into sh_eth_modify() -- this saves 84 bytes of code with ARM gcc 4.7.3. While at it, update Cogent Embedded's copyright. Signed-off-by:

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: -

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:

packet_snd and packet_rcv support virtio net headers for GSO. Move this logic into helper functions to be able to reuse it in tpacket_snd and tpacket_rcv. This is a straighforward code move with one exception. Instead of creating and passing a separate gso_type variable, reuse vnet_hdr.gso_type after conversion from virtio to kernel gso type.

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.

Nikolay Borisov says: ==================== Namespaceify more of the tcp sysctl knobs This patch series continues making more of the tcp-related sysctl knobs be per net-namespace. 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. I've split the patches to be per-sysctl but after the review if the outcome is positive I'm happy to either send it in one big blob or just. ==================== Signed-off-by: -
