Core & protocols
----------------
- Support usec resolution of TCP timestamps, enabled selectively by
a route attribute.
- Defer regular TCP ACK while processing socket backlog, try to send
a cumulative ACK at the end. Increase single TCP flow performance
on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).
- The Fair Queuing (FQ) packet scheduler:
- add built-in 3 band prio / WRR scheduling
- support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
- improve inactive flow reporting
- optimize the layout of structures for better cache locality
- Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
replacement for the old MD5 option.
- Add more retransmission timeout (RTO) related statistics to TCP_INFO.
- Support sending fragmented skbs over vsock sockets.
- Make sure we send SIGPIPE for vsock sockets if socket was shutdown().
- Add sysctl for ignoring lower limit on lifetime in Router
Advertisement PIO, based on an in-progress IETF draft.
- Add sysctl to control activation of TCP ping-pong mode.
- Add sysctl to make connection timeout in MPTCP configurable.
- Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
limit the number of wakeups.
- Support netlink GET for MDB (multicast forwarding), allowing user
space to request a single MDB entry instead of dumping the entire
table.
- Support selective FDB flushing in the VXLAN tunnel driver.
- Allow limiting learned FDB entries in bridges, prevent OOM attacks.
- Allow controlling via configfs netconsole targets which were created
via the kernel cmdline at boot, rather than via configfs at runtime.
- Support multiple PTP timestamp event queue readers with different
filters.
- MCTP over I3C.
BPF
---
- Add new veth-like netdevice where BPF program defines the logic
of the xmit routine. It can operate in L3 and L2 mode.
- Support exceptions - allow asserting conditions which should
never be true but are hard for the verifier to infer.
With some extra flexibility around handling of the exit / failure.
https://lwn.net/Articles/938435/
- Add support for local per-cpu kptr, allow allocating and storing
per-cpu objects in maps. Access to those objects operates on
the value for the current CPU. This allows to deprecate local
one-off implementations of per-CPU storage like
BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.
- Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
for systemd to re-implement the LogNamespace feature which allows
running multiple instances of systemd-journald to process the logs
of different services.
- Enable open-coded task_vma iteration, after maple tree conversion
made it hard to directly walk VMAs in tracing programs.
- Add open-coded task, css_task and css iterator support.
One of the use cases is customizable OOM victim selection via BPF.
- Allow source address selection with bpf_*_fib_lookup().
- Add ability to pin BPF timer to the current CPU.
- Prevent creation of infinite loops by combining tail calls and
fentry/fexit programs.
- Add missed stats for kprobes to retrieve the number of missed kprobe
executions and subsequent executions of BPF programs.
- Inherit system settings for CPU security mitigations.
- Add BPF v4 CPU instruction support for arm32 and s390x.
Changes to common code
----------------------
- overflow: add DEFINE_FLEX() for on-stack definition of structs
with flexible array members.
- Process doc update with more guidance for reviewers.
Driver API
----------
- Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
mutex in most places and remove a lot of smaller locks.
- Create a common DPLL configuration API. Allow configuring
and querying state of PLL circuits used for clock syntonization,
in network time distribution.
- Unify fragmented and full page allocation APIs in page pool code.
Let drivers be ignorant of PAGE_SIZE.
- Rework PHY state machine to avoid races with calls to phy_stop().
- Notify DSA drivers of MAC address changes on user ports, improve
correctness of offloads which depend on matching port MAC addresses.
- Allow antenna control on injected WiFi frames.
- Reduce the number of variants of napi_schedule().
- Simplify error handling when composing devlink health messages.
Misc
----
- A lot of KCSAN data race "fixes", from Eric.
- A lot of __counted_by() annotations, from Kees.
- A lot of strncpy -> strscpy and printf format fixes.
- Replace master/slave terminology with conduit/user in DSA drivers.
- Handful of KUnit tests for netdev and WiFi core.

This release completes the SunRPC thread scheduler work that was
begun in v6.6. The scheduler can now find an svc thread to wake in
constant time and without a list walk. Thanks again to Neil Brown
for this overhaul.
Lorenzo Bianconi contributed infrastructure for a netlink-based
NFSD control plane. The long-term plan is to provide the same
functionality as found in /proc/fs/nfsd, plus some interesting
additions, and then migrate the NFSD user space utilities to
netlink.
A long series to overhaul NFSD's NFSv4 operation encoding was
applied in this release. The goals are to bring this family of
encoding functions in line with the matching NFSv4 decoding
functions and with the NFSv2 and NFSv3 XDR functions, preparing
the way for better memory safety and maintainability.
A further improvement to NFSD's write delegation support was
contributed by Dai Ngo. This adds a CB_GETATTR callback,
enabling the server to retrieve cached size and mtime data from
clients holding write delegations. If the server can retrieve
this information, it does not have to recall the delegation in
some cases.
The usual panoply of bug fixes and minor improvements round out
this release. As always I am grateful to all contributors,
reviewers, and testers.

devlink: finish conversion to generated split_ops
This patchset converts the remaining genetlink commands to generated
split_ops and removes the existing small_ops arrays entirely
alongside with shared netlink attribute policy.
Patches #1-#6 are just small preparations and small fixes on multiple
places. Note that couple of patches contain the "Fixes"
tag but no need to put them into -net tree.
Patch #7 is a simple rename preparation
Patch #8 is the main one in this set and adds actual definitions of cmds
in to yaml file.
Patches #9-#10 finalize the change removing bits that are no longer in
use.

Currently, some of the commands are not described in devlink yaml file
and are manually filled in net/devlink/netlink.c in small_ops. To make
all part of split_ops, add definitions of the rest of the commands
alongside with needed attributes and enums.
Note that this focuses on the kernel side. The requests are fully
described in order to generate split_op alongside with policies.
Follow-up will describe the replies in order to make the userspace
helpers complete.

checkpatch gets confused and treats __attribute__ as a function call.
It complains about white space before "(":
WARNING:SPACING: space prohibited between function name and open parenthesis '('
+ struct netdev_queue_get_rsp obj __attribute__ ((aligned (8)));
No spaces wins in the kernel:
$ git grep 'attribute__((.*aligned(' | wc -l

$ git grep 'attribute__ ((.*aligned (' | wc -l

$ git grep 'attribute__ ((.*aligned(' | wc -l

So, whatever, change the codegen.
Note that checkpatch also thinks we should use __aligned(),
but this is user space code.

As far as I can tell the normal Makefile dependency tracking
works, generated files get re-generated if the YAML was updated.
Let make do its job, don't force the re-generation.
make hardclean can be used to force regeneration.

Unrelated updates:
- include tools/include/uapi to pick the latest kernel uapi headers
- print "xdp-features" and "xdp-rx-metadata-features" so it's clear

The inability to include the uAPI headers directly in tools/
is one of the bigger annoyances of compiling user space code.
Most projects trade the pain for smaller inconvenience of having
to copy the headers under tools/include.
In case of netlink headers I think that we can avoid both.
Netlink family headers are simple and should be self-contained.
We can try to twiddle the Makefile a little to force-include
just the family header, and use system headers for the rest.
This works fairly well. There are two warts - for some reason
if we specify -include $path/family.h as a compilation flag,
the #ifdef header guard does not seem to work. So we need
to throw the guard in on the command line as well. Seems like
GCC detects that the header is different and tries to include
both. Second problem is that make wants hash sign to be escaped
or not depending on the version. Sigh.

Generate the protocol code for ethtool. Skip the stats
for now, they are the only outlier in terms of complexity.
Stats are a sort-of semi-polymorphic (attr space of a nest
depends on value of another attr) or a type-value-scalar,
depending on how one wants to look at it...
A challenge for another time.

Commit e7c5433c5a ("tools: ynl: Remove duplicated include

an auto-generated file, and there's already a proper fix

Admittedly the devlink.yaml spec is fairly limitted,
it only covers basic device get and info-get ops.
That's sufficient to be useful (monitoring FW versions
in the fleet). Plus it gives us a chance to exercise
deep nesting and directional messaging in YNL.
