KVM/arm64 fixes for 6.12, take #1

- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

ASoC: Fixes for v6.12

A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.

Merge tag 'net-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"The zero-copy changes are relatively significant, but regression risk
should be contained. The feature needs to be used to cause trouble.

Also it feels like we got an order of magnitude more semi-automated
"refactoring" chaff than usual, I wonder if it's just us.

Core & protocols:

- Support Device Memory TCP, ability to zero-copy receive TCP
payloads to a DMABUF region of memory while packet headers land
separately in normal kernel buffers, and TCP processes then as
usual.

- The ability to read the PTP PHC (Physical Hardware Clock) alongside
MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
only CLOCK_REALTIME was supported.

- Allow matching on all bits of IP DSCP for routing decisions.
Previously we only supported on matching TOS bits in IPv4 which is
a narrower interpretation of the same header field.

- Increase the range of weights used for multi-path routing from
8 bits to 16 bits.

- Add support for IPv6 PIO p flag in the Prefix Information Option
per draft-ietf-6man-pio-pflag.

- IPv6 IOAM6 support for new tunsrc encap mode for better
performance.

- Detect destinations which blackhole MPTCP traffic and avoid
initiating MPTCP connections to them for a certain period of time,
1h by default.

- Improve IPsec control path performance by removing the inexact
policies list.

- AF_VSOCK: add support for SIOCOUTQ ioctl.

- Add enum for reasons TCP reset was sent for easier tracing.

- Add SMC ringbufs usage statistics.

Drivers:

- Handle netconsole setup failures more gracefully, don't fail
loading, retain the specified target as disabled.

- Extend bonding's IPsec offload pass thru capabilities (ESN, stats).

Filtering:

- Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
when long-lived sockets miss a chance to set additional callbacks
if a sockops program was not attached early in their lifetime.

- Support using BPF skb helpers in tracepoints.

- Conntrack Netlink: support CTA_FILTER for flush.

- Improve SCTP support in nfnetlink_queue.

- Improve performance of large nftables flush transactions.

Things we sprinkled into general kernel code:

- selftests: support setting an "interpreter" for script files; make
it easy to run as separate cases tests where one "interpreter" is
fed various test descriptions (in our case packet sequences).

Driver API:

- Extend core and ethtool APIs to support many PHYs connected to a
single interface (PHY topologies).

- Extend cable diagnostics to specify whether Time Domain
Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
used.

- Add library for implementing MAC-PHY Ethernet drivers for SPI
devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
Interface (TC6) standard.

- Add helpers to the PHY framework, for PHYs following the Open
Alliance standards:
- 1000BaseT1 link settings
- cable test and diagnostics

- Support listing / dumping all allocated RSS contexts.

- Add configuration for frequency Embedded SYNC in DPLL, which
magically embeds sync pulses into Ethernet signaling.

Merge branch 'net-selftests-tcp-ao-selftests-updates'

Dmitry Safonov via says:

====================
net/selftests: TCP-AO selftests updates

First 3 patches are more-or-less cleanups/preparations.

Patches 4/5 are fixes for netns file descriptors leaks/open.

Patch 6 was sent to me/contributed off-list by Mohammad, who wants 32-bit
kernels to run TCP-AO.

Patch 7 is a workaround/fix for slow VMs. Albeit, I can't reproduce
the issue, but I hope it will fix netdev flakes for connect-deny-*
tests.

And the biggest change is adding TCP-AO tracepoints to selftests.
I think it's a good addition by the following reasons:
- The related tracepoints are now tested;
- It allows tcp-ao selftests to raise expectations on the kernel
behavior - up from the syscalls exit statuses + net counters.
- Provides tracepoints usage samples.

As tracepoints are not a stable ABI, any kernel changes done to them
will be reflected to the selftests, which also will allow users
to see how to change their code. It's quite better than parsing dmesg
(what BGP was doing pre-tracepoints, ugh).

Somewhat arguably, the code parses trace_pipe, rather than uses
libtraceevent (which any sane user should do). The reason behind that is
the same as for rt-netlink macros instead of libmnl: I'm trying
to minimize the library dependencies of the selftests. And the
performance of formatting text in kernel and parsing it again in a test
is not critical.

Current output sample:
> ok 73 Trace events matched expectations: 13 tcp_hash_md5_required[2] tcp_hash_md5_unexpected[4] tcp_hash_ao_required[3] tcp_ao_key_not_found[4]

Previously, tracepoints selftests were part of kernel tcp tracepoints
submission [1], but since then the code was quite changed:
- Now generic tracing setup is in lib/ftrace.c, separate from
lib/ftrace-tcp.c which utilizes TCP trace points. This separation
allows future selftests to trace non-TCP events, i.e. to find out
an skb's drop reason, which was useful in the creation of TCP-CLOSE
stress-test (not in this patch set, but used in attempt to reproduce
the issue from [2]).
- Another change is that in the previous submission the trace events
where used only to detect unexpected TCP-AO/TCP-MD5 events. In this
version the selftests will fail if an expected trace event didn't
appear.
Let's see how reliable this is on the netdev bot - it obviously passes
on my testing, but potentially may require a temporary XFAIL patch
if it misbehaves on a slow VM.

selftests/net: Add trace events matching to tcp_ao

Setup trace points, add a new ftrace instance in order to not interfere
with the rest of the system, filtering by net namespace cookies.
Raise a new background thread that parses trace_pipe, matches them with
the list of expected events.

Wiring up trace events to selftests provides another insight if there is
anything unexpected happining in the tcp-ao code (i.e. key rotation when
it's not expected).

Note: in real programs libtraceevent should be used instead of this
manual labor of setting ftrace up and parsing. I'm not using it here
as I don't want to have an .so library dependency that one would have to
bring into VM or DUT (Device Under Test). Please, don't copy it over
into any real world programs, that aren't tests.

selftests/net: Open /proc/thread-self in open_netns()

It turns to be that open_netns() is called rarely from the child-thread
and more often from parent-thread. Yet, on initialization of kconfig
checks, either of threads may reach kconfig_lock mutex first.
VRF-related checks do create a temporary ksft-check VRF in
an unshare()'d namespace and than setns() back to the original.
As original was opened from "/proc/self/ns/net", it's valid for
thread-leader (parent), but it's invalid for the child, resulting
in the following failure on tests that check has_vrfs() support:
> # ok 54 TCP-AO required on socket + TCP-MD5 key: prefailed as expected: Key was rejected by service
> # not ok 55 # error 381[unsigned-md5.c:24] Failed to add a VRF: -17

elsewhere. There's also a big overhaul of the DAPM documentation from
Luca Ceresoli arising from the work he did putting together his recent
ELC talk, and he also contributed a new tool for visualising the DAPM
state.

- A new tool dapm-graph for visualising the DAPM state.
- Substantial fixes and clarifications for the DAPM documentation.
- Very large updates throughout the Intel audio drivers.
- Cleanups of accessors for driver data, module labelling, and for
constification.
- Modernsation and cleanup work in the Mediatek drivers.
- Several fixes and features for the DaVinci I2S driver.
- New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
