Merge tag 'net-next-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"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.

- AppleTalk COPS.

- AppleTalk ipddp.

- TI AR7 CPMAC Ethernet driver.

vlynq: remove bus driver

There are no users with a vlynq_driver in the Kernel tree. Also, only
the AR7 platform ever initialized a VLYNQ bus, but AR7 is going to be
removed from the Kernel. OpenWRT had some out-of-tree drivers which they
probably intended to upport, but AR7 devices are even there not
supported anymore because they are "stuck with Kernel

Merge branch 'dpll-api'

Vadim Fedorenko says:

====================
Create common DPLL configuration API

Implement common API for DPLL configuration and status reporting.
The API utilises netlink interface as transport for commands and event
notifications. This API aims to extend current pin configuration
provided by PTP subsystem and make it flexible and easy to cover
complex configurations.

Netlink interface is based on ynl spec, it allows use of in-kernel
tools/net/ynl/cli.py application to control the interface with properly
formated command and json attribute strings. Here are few command
examples of how it works with `ice` driver on supported NIC:

- dump dpll devices:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--dump device-get
[{'clock-id': 4658613174691613800,

'mode': 'automatic',
'mode-supported': ['automatic'],

'id': 1,
'lock-status': 'locked-ho-acq',
'mode': 'automatic',
'mode-supported': ['automatic'],
'module-name': 'ice',
'type': 'pps'}]

- get single pin info:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-get --json '{"id":2}'
{'board-label': 'C827_0-RCLKA',

'prio': 9,
'state': 'disconnected'},
{'direction': 'input',
'parent-id': 1,
'prio': 9,
'state': 'disconnected'}],
'type': 'mux'}

- set pin's state on dpll:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-set --json '{"id":2, "parent-device":{"parent-id":1, "state":2}}'

- set pin's prio on dpll:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-set --json '{"id":2, "parent-device":{"parent-id":1, "prio":4}}'

- set pin's state on parent pin:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-set --json '{"id":13, "parent-pin":{"parent-id":2, "state":1}}'

- pin xarray uses id provided by the driver
- remove usage of PIN_IDX_INVALID in set function
- source_pin_get() returns object instead of idx
- fixes in frequency support API
* device and pin operations are const now
* small fixes in naming in Makefile and in the functions
* single mutex for the subsystem to avoid possible ABBA locks
* no special *_priv() helpers anymore, private data is passed as void*
* no netlink filters by name anymore, only index is supported
* update ptp_ocp and ice drivers to follow new API version
* add mlx5e driver as a new customer of the subsystem
v5 -> v6:

Provide userspace with clock class value of DPLL with dpll device
dump netlink request. Clock class is assigned by driver allocating
a dpll device. Clock class values are defined as specified in:
ITU-T G.8273.2/Y.1368.2 recommendation.
- dpll device naming schema use new pattern:
"dpll_%s_%d_%d", where:
- %s - dev_name(parent) of parent device,
- %d (1) - enum value of dpll type,
- %d (2) - device index provided by parent device.
- new muxed/shared pin registration:
Let the kernel module to register a shared or muxed pin without
finding it or its parent. Instead use a parent/shared pin
description to find correct pin internally in dpll_core, simplifing
a dpll API
* Implement complex DPLL design in ice driver (Arkadiusz)
* Remove ptp_ocp driver from the series for now
v3 -> v4:
* redesign framework to make pins dynamically allocated (Arkadiusz)

dpll: core: Add DPLL framework base functions

DPLL framework is used to represent and configure DPLL devices
in systems. Each device that has DPLL and can configure inputs
and outputs can use this framework.

Implement core framework functions for further interactions
with device drivers implementing dpll subsystem, as well as for
interactions of DPLL netlink framework part with the subsystem
itself.
