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.

Merge branch 'seltests-xsk-various-improvements-to-xskxceiver'

Magnus Karlsson says:

====================
seltests/xsk: various improvements to xskxceiver

This patch set implements several improvements to the xsk selftests
test suite that I thought were useful while debugging the xsk
multi-buffer code and tests. The largest new feature is the ability to
be able to execute a single test instead of the whole test suite. This
required some surgery on the current code, details below.

Anatomy of the path set:

1: Print useful info on a per packet basis with the option -v

2: Add a timeout in the transmission loop too. We only used to have
one for the Rx thread, but Tx can lock up too waiting for
completions.

3: Add an option (-m) to only run the tests (or a single test with a
later patch) in a single mode: skb, drv, or zc (zero-copy).

4-5: Preparatory patches to be able to specify a test to run. Need to
define the test names in a single structure and their entry
points, so we can use this when wanting to run a specific test.

6: Adds a command line option (-l) that lists all the tests.

7: Adds a command line option (-t) that runs a specific test instead
of the whole test suite. Can be combined with -m to specify a
single mode too.

8: Use ksft_print_msg() uniformly throughout the tests. It was a mix
of printf() and ksft_print_msg() before.

9: In some places, we failed the whole test suite instead of a single
test in certain circumstances. Fix this so only the test in
question is failed and the rest of the test suite continues.

10: Display the available command line options with -h

v3 -> v4:
* Fixed another spelling error in patch #9 [Maciej]
* Only allow the actual strings for the -m command [Maciej]
* Move some code from patch #7 to #3 [Maciej]

v2 -> v3:
* Drop the support for environment variables. Probably not useful. [Maciej]
* Fixed spelling mistake in patch #9 [Maciej]
* Fail gracefully if unsupported mode is chosen [Maciej]
* Simplified test run loop [Maciej]

v1 -> v2:

* Introduce XSKTEST_MODE env variable to be able to set the mode to
use [Przemyslaw]
* Introduce XSKTEST_ETH env variable to be able to set the ethernet
interface to use by introducing a new patch (#11) [Magnus]
* Fixed spelling error in patch #5 [Przemyslaw, Maciej]
* Fixed confusing documentation in patch #10 [Przemyslaw]
* The -l option can now be used without being root [Magnus, Maciej]
* Fixed documentation error in patch #7 [Maciej]
* Added error handling to the -t option [Maciej]
* -h now displayed as an option [Maciej]
