      net/mlx4_core: Add basic support for TCP/IP offloads under tunneling · 7ffdf726
      由 Or Gerlitz 提交于 
      Add the low-level device commands and definitions used for TCP/IP HW offloads
of tunneled/vxlan traffic which are supported by the ConnectX3-pro NIC.

This is done through the following elements:

 - read tunneling device caps in QUERY_DEV_CAP
 - add helper function to do SET_PORT for tunneling
 - add DMFS VXLAN steering rule definitions
 - add CQE and WQE checksum offload field definitions

      netlink: specify netlink packet direction for nlmon · 604d13c9
      由 Daniel Borkmann 提交于 
      In order to facilitate development for netlink protocol dissector,
fill the unused field skb->pkt_type of the cloned skb with a hint
of the address space of the new owner (receiver) socket in the
notion of "to kernel" resp. "to user".

At the time we invoke __netlink_deliver_tap_skb(), we already have
set the new skb owner via netlink_skb_set_owner_r(), so we can use
that for netlink_is_kernel() probing.

In normal PF_PACKET network traffic, this field denotes if the
packet is destined for us (PACKET_HOST), if it's broadcast
(PACKET_BROADCAST), etc.

As we only have 3 bit reserved, we can use the value (= 6) of
PACKET_FASTROUTE as it's _not used_ anywhere in the whole kernel
and not supported anywhere, and packets of such type were never
exposed to user space, so there are no overlapping users of such
kind. Thus, as wished, that seems the only way to make both
PACKET_* values non-overlapping and therefore device agnostic.

By using those two flags for netlink skbs on nlmon devices, they
can be made available and picked up via sll_pkttype (previously
unused in netlink context) in struct sockaddr_ll. We now have
these two directions:

 - PACKET_USER (= 6)    ->  to user space
 - PACKET_KERNEL (= 7)  ->  to kernel space

Partial `ip a` example strace for sa_family=AF_NETLINK with
detected nl msg direction:

syscall:                     direction:
sendto(3,  ...) = 40         /* to kernel */
recvmsg(3, ...) = 3404       /* to user */
recvmsg(3, ...) = 1120       /* to user */
recvmsg(3, ...) = 20         /* to user */
sendto(3,  ...) = 40         /* to kernel */
recvmsg(3, ...) = 168        /* to user */
recvmsg(3, ...) = 144        /* to user */
recvmsg(3, ...) = 20         /* to user */

      printk: Add a DEPRECATED macro · 0a9a8bfd
      由 Neil Horman 提交于 
      sctp has several points in its setsockopt path in which it issues deprecation
warnings.  It seems like it might be handy to macrotize such a warning so other
subsystems can use it easily

      net: Allow setting sock flow hash without a sock · fe477558
      由 Tom Herbert 提交于 
      This patch adds sock_rps_record_flow_hash and sock_rps_reset_flow_hash
which take a hash value as an argument and sets the sock_flow_table
accordingly.  This allows the table to be populated in cases where flow
is being tracked outside of a sock structure.

sock_rps_record_flow and sock_rps_reset_flow call this function
where the hash is taken from sk_rxhash.
