ASoC: Fixes for v7.1

A bigger batch of fixes than usual due to -next not happeing last week,
this is mostly stuff for laptops - a lot of quirks and small fixes,
mainly for x86 and SoundWire. Nothing too big or exciting individually,
just two week's worth.

tools/selftests: Add a VXLAN+IPsec traffic test

There are VXLAN tests and IPsec tests, but there is no test that
combines the two protocols and exercises the tunnel-over-ipsec code
paths. Fix that by adding a traffic test with VXLAN and IPsec using
crypto offload. This is runnable on HW which supports ESP offload (so no
nsim unfortunately).

Traffic is done with iperf3 and the test validates that there are no
packet drops and iperf3 can get to at least 100 Mbps (a very
conservative value on today's crypto offload HW, as it can typically
reach multi-Gbps rates).

Ran right now, the test fails due to a recently exposed bug in xfrm,
which will be fixed in the next patch:

"Core & protocols:

- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP

- Number of code moves to help the compiler with inlining. Avoid
output arguments for returning drop reason where possible

- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints

- Remove the rtnl_lock use from IP Multicast Routing

- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two

- Report TCP delayed ack timer information via socket diag

- Add ip_local_port_step_width sysctl to allow distributing the
randomly selected ports more evenly throughout the allowed space

- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage

- Remove UDP-Lite support (as announced in 2023)

- Remove support for building IPv6 as a module. Remove the now
unnecessary function calling indirection

Cross-tree stuff:

- Move Michael MIC code from generic crypto into wireless, it's
considered insecure but some WiFi networks still need it

Netfilter:

- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.

Florian W reports this gets us ~13% higher packet rate

- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex

- Add more opinionated input validation to lower security exposure

- Make IPVS hash tables to be per-netns and resizable

Wireless:

- Finished assoc frame encryption/EPPKE/802.1X-over-auth

- Radar detection improvements

- Add 6 GHz incumbent signal detection APIs

Merge branch 'add-tso-map-once-dma-helpers-and-bnxt-sw-uso-support'

Joe Damato says:

====================
Add TSO map-once DMA helpers and bnxt SW USO support

Greetings:

This series extends net/tso to add a data structure and some helpers allowing
drivers to DMA map headers and packet payloads a single time. The helpers can
then be used to reference slices of shared mapping for each segment. This
helps to avoid the cost of repeated DMA mappings, especially on systems which
use an IOMMU. N per-packet DMA maps are replaced with a single map for the
entire GSO skb. As of v3, the series uses the DMA IOVA API (as suggested by
Leon [1]) and provides a fallback path when an IOMMU is not in use. The DMA
IOVA API provides even better efficiency than the v2; see below.

The added helpers are then used in bnxt to add support for software UDP
Segmentation Offloading (SW USO) for older bnxt devices which do not have
support for USO in hardware. Since the helpers are generic, other drivers
can be extended similarly.

The v2 showed a ~4x reduction in DMA mapping calls at the same wire packet
rate on production traffic with a bnxt device. The v3, however, shows a larger
reduction of about ~6x at the same wire packet rate. This is thanks to Leon's
suggestion of using the DMA IOVA API [1].

Special care is taken to make bnxt ethtool operations work correctly: the ring
size cannot be reduced below a minimum threshold while USO is enabled and
growing the ring automatically re-enables USO if it was previously blocked.

This v10 contains some cosmetic changes (wrapping long lines), moves the test
to the correct directory, and attempts to fix the slot availability check
added in the v9.

I re-ran the python test and the test passed on my bnxt system. I also ran
this on a production system.

Add a test for ethtool NFC (ntuple) flow steering rules. The test
creates an ntuple rule matching on various flow fields and verifies
that traffic is steered to the correct queue.

The test forces all traffic to queue 0 via the indirection table,
then installs an ntuple rule to steer select traffic to a specific
queue. The test then verifies the expected number of packets is received
on the queue.

This test has variants for TCP/UDP over IPv4/IPv6, with rules matching
the source IP. Additional match fields will be added in the next commit.

Merge branch 'netkit-support-for-io_uring-zero-copy-and-af_xdp'

Daniel Borkmann says:

====================
netkit: Support for io_uring zero-copy and AF_XDP

Containers use virtual netdevs to route traffic from a physical netdev
in the host namespace. They do not have access to the physical netdev
in the host and thus can't use memory providers or AF_XDP that require
reconfiguring/restarting queues in the physical netdev.

This patchset adds the concept of queue leasing to virtual netdevs that
allow containers to use memory providers and AF_XDP at native speed.
Leased queues are bound to a real queue in a physical netdev and act
as a proxy.

Memory providers and AF_XDP operations take an ifindex and queue id,
so containers would pass in an ifindex for a virtual netdev and a queue
id of a leased queue, which then gets proxied to the underlying real
queue.

We have implemented support for this concept in netkit and tested the
latter against Nvidia ConnectX-6 (mlx5) as well as Broadcom BCM957504
(bnxt_en) 100G NICs. For more details see the individual patches.

Merge branch 'selftests-drivers-bash-support-for-remote-traffic-generators'

====================
selftests: drivers: bash support for remote traffic generators

This patch set aims to add the necessary support so that bash written
selftests are also able to easily run with a remote traffic generator
system, either be it in another netns or one accessible through ssh.

This patch set is a result of the discussion from v1:
https://lore.kernel.org/all/20260303084330.340b6459@kernel.org/
Even though the python infrastructure is already established, some
things are easier in bash and it would be a shame to leave behind the
bash tests that we already have.

This support is based on the requirements described in the
tools/testing/selftests/drivers/net/README.rst file.

Mainly, the drivers/net selftests should be able to run on a interface
specified through the NETIF env variable. On top of that, variables such
as REMOTE_TYPE and REMOTE_ARGS define how the remote traffic generator
can be accessed. Patch 3/10 parses these env variables and constructs the
NETIFS array that bash tests are accustomed to. This is with the
intention of enabling already written tests to incur minimal changes.

The second patch also defines the TARGETS array which will hold the
necessary information about the target on which a specific interface
is located.

For example, a net.config which looks like below:
NETIF=eth0
LOCAL_V4=192.168.1.1
REMOTE_V4=192.168.1.2
REMOTE_TYPE=ssh
REMOTE_ARGS=root@192.168.1.2

will generate the NETIFS and TARGETS arrays with the following data.

NETIFS[p1]="eth0"
NETIFS[p2]="eth2"

TARGETS[eth0]="local:"
TARGETS[eth2]="ssh:root@192.168.1.2"

The above will be true if on the remote target, the interface which has
the 192.168.1.2 address is named eth2.

The values held in the TARGETS array will be used by the new 'run_on'
helper added in patch 2/10 to know how to run a specific command, on the
local system, on another netns or by using ssh. Patch 4/10 updates some
helpers to use run_on so that, for example, lib.sh is able to ensure
stable MAC addresses even with the remote interface located in another
netns.

The next 5 patches, 5/10-9/10 update the ethtool_rmon.sh script so that it
can work with the kselftest infrastructure and the new
NETIF/REMOTE_TYPE etc way of working. Beside updating each ip link or
ethtool command to use the run_on helper, the patches also remove any
testing done on the remote interface.

The last patch adds a new test which checks the standard counters -
eth-ctrl, eth-mac and pause - and uses the new infrastructure put in
place by the first patches.

With this patch set, both tests can be run using a net.config file and
run_kselftest.sh as shown below.

selftests: drivers: hw: add test for the ethtool standard counters

Add a new selftest - ethtool_std_stats.sh - which validates the
eth-ctrl, eth-mac and pause standard statistics exported by an
interface. Collision related eth-mac counters as well as the error ones
will be checked against zero since that is the most likely correct
scenario.

The central part of this patch is the traffic_test() function which
gathers the 'before' counter values, sends a batch of traffic and then
interrogates again the same counters in order to determine if the delta
is on target. The function receives an array through which the caller
can request what counters to be interrogated and, for each of them, what
is their target delta value.

The output from this selftest looks as follows on a LX2160ARDB board:

Please note that not all MACs are counting the software injected pause
frames as real Tx pause. For example, on a LS1028ARDB the selftest
output will reflect the fact that neither the ENETC MAC, nor the Felix
switch MAC are able to detect Tx pause frames injected by software.

$ ./run_kselftest.sh -t drivers/net/hw:ethtool_std_stats.sh

selftests: drv-net: xdp: Add rss_hash metadata tests

This test loads xdp_metadata.bpf which calls bpf_xdp_metadata_rx_hash() on
incoming packets. The metadata from that packet is then sent to a BPF
map for validation. It borrows structure from xdp.py, reusing common
functions.

The test checks the device's xdp-rx-metadata-features via netlink
before running and skips on devices that do not advertise hash support.
This can be run on veth devices as well as real hardware.

The test is fairly simple and just verifies that a TCP or UDP packet can be
identified as an L4 flow. This minimal test also passes if run on a veth
device.

selftests: drv-net: gro: test GRO stats

Test accuracy of GRO stats. We want to cover two potentially tricky
cases:
- single segment GRO
- packets which were eligible but didn't get GRO'd

The first case is trivial, teach gro.c to send one packet, and check
GRO stats didn't move.

Second case requires gro.c to send a lot of flows expecting the NIC
to run out of GRO flow capacity.

To avoid system traffic noise we steer the packets to a dedicated
queue and operate on qstat.
