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

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 'am-qt2025-phy-rust'

FUJITA Tomonori says:

====================
net: phy: add Applied Micro QT2025 PHY driver

This patchset adds a PHY driver for Applied Micro Circuits Corporation
QT2025.

The first patch adds Rust equivalent to include/linux/sizes.h, makes
code more readable. The 2-5th patches update the PHYLIB Rust bindings.
The 4th and 5th patches have been reviewed previously in a different
thread [1].

QT2025 PHY support was implemented as a part of an Ethernet driver for
Tehuti Networks TN40xx chips. Multiple vendors (DLink, Asus, Edimax,
QNAP, etc) developed adapters based on TN40xx chips. Tehuti Networks
went out of business and the driver wasn't merged into mainline. But
it's still distributed with some of the hardware (and also available
on some vendor sites).

The original driver handles multiple PHY hardware (AMCC QT2025, TI
TLK10232, Aqrate AQR105, and Marvell MV88X3120, MV88X3310, and
MV88E2010). I divided the original driver into MAC and PHY drivers and
implemented a QT2025 PHY driver in Rust.

The MAC driver for Tehuti Networks TN40xx chips was already merged in
6.11-rc1. The MAC and this PHY drivers have been tested with Edimax
EN-9320SFP+ 10G network adapter.

Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.

Core & protocols:

- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes

This improves TCP performances with many concurrent connections up
to 40%

- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks

- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination

- Refactor the TCP bind conflict code, shrinking related socket
structs

- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF

- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it

- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations

- Reduce extension header parsing overhead at GRO time

- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries

- Reorder nftables struct members, to keep data accessed by the
datapath first

- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer

- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)

- More data-race annotations

- Extend the diag interface to dump TCP bound-only sockets

- Conditional notification of events for TC qdisc class and actions

- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID

- Implement SMCv2.1 virtual ISM device support

- Add support for Batman-avd mulicast packet type

BPF:

- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes

- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload

- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y

- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques

- Support uid/gid options when mounting bpffs

- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is
identified by its id

- Extend verifier to allow bpf_refcount_acquire() of a map value
field obtained via direct load which is a use-case needed in
sched_ext

- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter

- Support for VLAN tag in XDP hints

- Remove deprecated bpfilter kernel leftovers given the project is
developed in user-space (https://github.com/facebook/bpfilter)

Misc:

- Support for parellel TC self-tests execution

- Increase MPTCP self-tests coverage

- Updated the bridge documentation, including several so-far
undocumented features

- Convert all the net self-tests to run in unique netns, to avoid
random failures due to conflict and allow concurrent runs

- Add TCP-AO self-tests

- Add kunit tests for both cfg80211 and mac80211

- Autogenerate Netlink families documentation from YAML spec

- Add yml-gen support for fixed headers and recursive nests, the tool
can now generate user-space code for all genetlink families for
which we have specs

- A bunch of additional module descriptions fixes

- Catch incorrect freeing of pages belonging to a page pool

Driver API:

- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust

- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship

- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances

- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host

- Add support for ethtool symmetric-xor RSS hash

Merge branch 'net-phy-rust'

FUJITA Tomonori says:

====================
Rust abstractions for network PHY drivers

No functional change since v10; only comment and commit log updates.

This patchset adds Rust abstractions for phylib. It doesn't fully
cover the C APIs yet but I think that it's already useful. I implement
two PHY drivers (Asix AX88772A PHYs and Realtek Generic FE-GE). Seems
they work well with real hardware.

The first patch introduces Rust bindings for phylib.

The second patch adds a macro to declare a kernel module for PHYs
drivers.

The third adds the Rust ETHERNET PHY LIBRARY entry to MAINTAINERS
file; adds the binding file and me as a maintainer (as Andrew Lunn
suggested) with Trevor Gross as a reviewer.

The last patch introduces the Rust version of Asix PHY driver,
drivers/net/phy/ax88796b.c. The features are equivalent to the C
version. You can choose C (by default) or Rust version on kernel
configuration.
