This is a preliminary step to allow fast socket lookup of SO_REUSEPORT groups. Doing so with a BPF filter will require access to the skb in question. This change plumbs the skb (and offset to payload data) through the call stack to the listening socket lookup implementations where it will be used in a following patch. Signed-off-by:

tcp_hdrlen is wasteful if you already have a pointer to struct tcphdr. This splits the size calculation into a helper function that can be used if a struct tcphdr is already available. Signed-off-by:

In order to support fast lookups for TCP sockets with SO_REUSEPORT, the function that adds sockets to the listening hash set needs to be able to check receive address equality. Since this equality check is different for IPv4 and IPv6, we will need two different socket hashing functions. This patch adds inet6_hash identical to the existing inet_hash function and updates the appropriate references. A following patch will differentiate the two by passing different comparison functions to __inet_hash. Additionally, in order to use the IPv6 address equality function from inet6_hashtables (which is compiled as a built-in object when IPv6 is enabled) it also needs to be in a built-in object file as well. This moves ipv6_rcv_saddr_equal into inet_hashtables to accomplish this. Signed-off-by:

In order to support fast reuseport lookups in TCP, the hash function defined in struct proto must be capable of returning an error code. This patch changes the function signature of all related hash functions to return an integer and handles or propagates this return value at all call sites. Signed-off-by:

Antonio Quartulli says: ==================== Here you have a batch of patches by Sven Eckelmann that drops our private reference counting implementation and substitutes it with the kref objects/functions. Then you have a patch, by Simon Wunderlich, that makes the broadcast protection window code more generic so that it can be re-used in the future by other components with different requirements. Lastly, Sven is also introducing two lockdep asserts in functions operating on our TVLV container list, to make sure that the proper lock is always acquired by the users. ==================== Signed-off-by: -

>From FW version 11.0. onwards, the PORT_MISCONFIG event generated by the FW will carry more information about the event in the "data_word1" and "data_word2" fields. This patch adds support in the driver to parse the new information and log it accordingly. This patch also changes some of the messages that are being logged currently. Signed-off-by:

Currently we request RSS capability even if a single Rx ring is created. As a result in few cases we unnecessarily consume an RSS capable interface which is a limited resource in the chip. This patch enables RSS on an interface only if more than one Rx ring is created. Signed-off-by:

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:

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.
