This series provides the following updates to mlx5e netdevice driver.
1) First 4 patches extends the support for ethtool rxnfc flow steering
- Added ipv6 support
- l4 proto ip field for both ip6 and ip4
2) Next 4 patches, reorganizing flow steering structures and declaration into
one header file, and add two Kconfig flags to allow disabling/enabling mlx5
netdevice rx flow steering at compile time:
CONFIG_MLX5_EN_ARFS for en_arfs.c
CONFIG_MLX5_EN_RXNFC for en_fs_ehtool.c
3) More kconfig flags dependencies
- vxlan.c depends on CONFIG_VXLAN

pull-request: bpf-next 2018-08-13
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add driver XDP support for veth. This can be used in conjunction with
redirect of another XDP program e.g. sitting on NIC so the xdp_frame
can be forwarded to the peer veth directly without modification,
from Toshiaki.
2) Add a new BPF map type REUSEPORT_SOCKARRAY and prog type SK_REUSEPORT
in order to provide more control and visibility on where a SO_REUSEPORT
sk should be located, and the latter enables to directly select a sk
from the bpf map. This also enables map-in-map for application migration
use cases, from Martin.
3) Add a new BPF helper bpf_skb_ancestor_cgroup_id() that returns the id
of cgroup v2 that is the ancestor of the cgroup associated with the
skb at the ancestor_level, from Andrey.
4) Implement BPF fs map pretty-print support based on BTF data for regular
hash table and LRU map, from Yonghong.
5) Decouple the ability to attach BTF for a map from the key and value
pretty-printer in BPF fs, and enable further support of BTF for maps for
percpu and LPM trie, from Daniel.
6) Implement a better BPF sample of using XDP's CPU redirect feature for
load balancing SKB processing to remote CPU. The sample implements the
same XDP load balancing as Suricata does which is symmetric hash based
on IP and L4 protocol, from Jesper.
7) Revert adding NULL pointer check with WARN_ON_ONCE() in __xdp_return()'s
critical path as it is ensured that the allocator is present, from Björn.

There is an unalignment access about the structure
'trace_event_raw_fib_table_lookup'.
In include/trace/events/fib.h, there is a memory operation which casting
the 'src' data member to a pointer, and then store a value to this
pointer point to.
p32 = (__be32 *) __entry->src;
*p32 = flp->saddr;
The offset of 'src' in structure trace_event_raw_fib_table_lookup is not
four bytes alignment. On some architectures, they don't permit the
unalignment access, it need to pay the price to handle this situation in
exception handler.
Adjust the layout of structure to avoid this case.

There have been two reports that network doesn't come back on resume
from suspend when using MSI-X. Both cases affect the same chip version
(RTL8168g - version 40), on different systems. Falling back to MSI

version is to blame, let's disable MSI-X for this version.

Preventing the kernel from responding to ICMP Echo Requests messages
can be useful in several ways. The sysctl parameter
'icmp_echo_ignore_all' can be used to prevent the kernel from
responding to IPv4 ICMP echo requests. For IPv6 pings, such
a sysctl kernel parameter did not exist.
Add the ability to prevent the kernel from responding to IPv6
ICMP echo requests through the use of the following sysctl
parameter : /proc/sys/net/ipv6/icmp/echo_ignore_all.

net/tls: Combined memory allocation for decryption request
This patch does a combined memory allocation from heap for scatterlists,
aead_request, aad and iv for the tls record decryption path. In present
code, aead_request is allocated from heap, scatterlists on a conditional
basis are allocated on heap or on stack. This is inefficient as it may
requires multiple kmalloc/kfree.
The initialization vector passed in cryption request is allocated on
stack. This is a problem since the stack memory is not dma-able from
crypto accelerators.
Doing one combined memory allocation for each decryption request fixes
both the above issues. It also paves a way to be able to submit multiple
async decryption requests while the previous one is pending i.e. being
processed or queued.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
For preparing decryption request, several memory chunks are required
(aead_req, sgin, sgout, iv, aad). For submitting the decrypt request to
an accelerator, it is required that the buffers which are read by the
accelerator must be dma-able and not come from stack. The buffers for
aad and iv can be separately kmalloced each, but it is inefficient.
This patch does a combined allocation for preparing decryption request
and then segments into aead_req || sgin || sgout || iv || aad.
