Pull networking updates from Jakub Kicinski:
"One of the 'small improvements all over the place' releases for us.

It's hard to draw any direct comparisons because summer vacations
disrupted our patch processing (and presumably - generation) quite a
bit.

Quick and dirty count suggests we (Paolo and I) merged a very similar
number of net (632) and net-next (648) patches. This is not telling
the full story either because 1/3 to 1/2 of the net-next patches also
*seem* like AI-driven low priority fixes, cleanups and clarifications.

We are completely overwhelmed, of course. The glimmer of hope is that
we secured sufficient LLM budget and access (thank you Meta!) to run
reviews with multiple frontier models on each patch. This eliminates
some hallucinations. That said, in terms of review, the LLMs can only
do so much.

The sad truth is that our APIs (especially for rare events like PCIe
errors, timeouts etc) have always been racy, and now LLMs don't let us
ignore that. I expect our direction for the next release will be to
tweak the reviews a little bit more, but start shifting focus to
letting the LLMs take care of the busy work - managing patchwork,
automating common process complaints, editing commit messages, and
maybe applying patches which already got "reviewed-by" tags from
people we trust...

Merge branch 'net-mctp-usb-add-support-for-mctp-over-usb-v1-1'

Jeremy Kerr says:

====================
net: mctp: usb: Add support for MCTP-over-USB v1.1

Version 1.1.0 of DSP0283 (MCTP over USB transport binding) has been
released, this patch series updates our current v1.0.1 support for the
changes in v1.1.x.

The major change in v1.1 is the introduction of "packet spanning" mode,
where a single MCTP packet may be split over multiple USB packets
(themselves forming a single USB bulk transfer). This relaxes the
requirement for USB high-speed mode, as we can now send MCTP packets
contained over multiple 64-byte full-speed USB bulk transfers, and gives
us an increase in the maximum MCTP packet size - we now have 13 bits of
packet length (previously 8) in the transport header.

Handling packet spanning introduces some complexity in the transmit and
receive paths, as we lose some constraints on where packet boundaries
may correspond to USB transfer boundaries, and may need to retain state
across separate transfers. To contain this complexity, we introduce a
new library for the transfer packing- and unpacking implementations,
"mctp-usblib". The host driver is a consumer of this library, and a
future gadget driver can use the same implementations. We can now also
implement tests on the API boundary of the library.

The series implements an incremental shift to mctp-usblib, then
implements packet spanning mode in the new library. We have a few
changes to prepare for this, in altering a few constants and
behaviours as v1.0-specific. Once packet spanning is implemented in
mctp-usblib, we enable it in the host-side driver.

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls)

- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.

- Support collecting TCP timestamps (data submitted, sent, acked) in
BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.

- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.

- Optimize MPTCP performance in single subflow mode by 29%.

- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream
performance up to 2x.

- Improve performance of contended connect() by 200% by searching for
an available 4-tuple under RCU rather than a spin lock. Bring an
additional 229% improvement by tweaking hash distribution.

- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.

- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.

- Avoid FIB lookup in netfilter if socket is available, 20% perf win.

- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles. There are up to 4
namespace roles but we used to have just 2 netns pointer arguments,
interpreted differently based on context.

- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.

- Add a new sysctl and sockopt for capping max retransmit timeout in
TCP.

- Support masking port and DSCP in routing rule matches.

- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.

- Support specifying at what time packet should be sent on AF_XDP
sockets.

- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin
users.

- Add Netlink YAML spec for WiFi (nl80211) and conntrack.

- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols
which only need to be exported when IPv6 support is built as a
module.

- Age FDB entries based on Rx not Tx traffic in VxLAN, similar to
normal bridging.

- Allow users to specify source port range for GENEVE tunnels.

- netconsole: allow attaching kernel release, CPU ID and task name to
messages as metadata

====================
mctp: Add MCTP-over-USB hardware transport binding

Add an implementation of the DMTF standard DSP0283, providing an MCTP
channel over high-speed USB.

This is a fairly trivial first implementation, in that we only submit
one tx and one rx URB at a time. We do accept multi-packet transfers,
but do not yet generate them on transmit.

Of course, questions and comments are most welcome, particularly on the
USB interfaces.

net: mctp: Add MCTP USB transport driver

Add an implementation for DMTF DSP0283, which defines a MCTP-over-USB
transport. As per that spec, we're restricted to full speed mode,
requiring 512-byte transfers.

Each MCTP-over-USB interface is a peer-to-peer link to a single MCTP
endpoint, so no physical addressing is required (of course, that MCTP
endpoint may then bridge to further MCTP endpoints). Consequently,
interfaces will report with no lladdr data:

# mctp link
dev lo index 1 address 00:00:00:00:00:00 net 1 mtu 65536 up
dev mctpusb0 index 6 address none net 1 mtu 68 up

This is a simple initial implementation, with single rx & tx urbs, and
no multi-packet tx transfers - although we do accept multi-packet rx
from the device.

- 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:

- 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.
