Merge tag 'net-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core:

- Implement the Device Memory TCP transmit path, allowing zero-copy
data transmission on top of TCP from e.g. GPU memory to the wire.

- Move all the IPv6 routing tables management outside the RTNL scope,
under its own lock and RCU. The route control path is now 3x times
faster.

- Convert queue related netlink ops to instance lock, reducing again
the scope of the RTNL lock. This improves the control plane
scalability.

- Refactor the software crc32c implementation, removing unneeded
abstraction layers and improving significantly the related
micro-benchmarks.

- Optimize the GRO engine for UDP-tunneled traffic, for a 10%
performance improvement in related stream tests.

- Cover more per-CPU storage with local nested BH locking; this is a
prep work to remove the current per-CPU lock in local_bh_disable()
on PREMPT_RT.

- Introduce and use nlmsg_payload helper, combining buffer bounds
verification with accessing payload carried by netlink messages.

Netfilter:

- Rewrite the procfs conntrack table implementation, improving
considerably the dump performance. A lot of user-space tools still
use this interface.

- Implement support for wildcard netdevice in netdev basechain and
flowtables.

- Integrate conntrack information into nft trace infrastructure.

- Export set count and backend name to userspace, for better
introspection.

BPF:

- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
programs and can be controlled in similar way to traditional qdiscs
using the "tc qdisc" command.

- Refactor the UDP socket iterator, addressing long standing issues
WRT duplicate hits or missed sockets.

Protocols:

- Improve TCP receive buffer auto-tuning and increase the default
upper bound for the receive buffer; overall this improves the
single flow maximum thoughput on 200Gbs link by over 60%.

- Add AFS GSSAPI security class to AF_RXRPC; it provides transport
security for connections to the AFS fileserver and VL server.

- Improve TCP multipath routing, so that the sources address always
matches the nexthop device.

- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
and thus preventing DoS caused by passing around problematic FDs.

- Retire DCCP socket. DCCP only receives updates for bugs, and major
distros disable it by default. Its removal allows for better
organisation of TCP fields to reduce the number of cache lines hit
in the fast path.

- Extend TCP drop-reason support to cover PAWS checks.

Driver API:

- Reorganize PTP ioctl flag support to require an explicit opt-in for
the drivers, avoiding the problem of drivers not rejecting new
unsupported flags.

- Converted several device drivers to timestamping APIs.

- Introduce per-PHY ethtool dump helpers, improving the support for
dump operations targeting PHYs.

Tests and tooling:

- Add support for classic netlink in user space C codegen, so that
ynl-c can now read, create and modify links, routes addresses and
qdisc layer configuration.

- Add ynl sub-types for binary attributes, allowing ynl-c to output
known struct instead of raw binary data, clarifying the classic
netlink output.

- Extend MPTCP selftests to improve the code-coverage.

- Add tests for XDP tail adjustment in AF_XDP.

New hardware / drivers:

- OpenVPN virtual driver: offload OpenVPN data channels processing to
the kernel-space, increasing the data transfer throughput WRT the
user-space implementation.

- Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.

- Broadcom asp-v3.0 ethernet driver.

- AMD Renoir ethernet device.

testing/selftests: add test tool and scripts for ovpn module

The ovpn-cli tool can be compiled and used as selftest for the ovpn
kernel module.

[NOTE: it depends on libmedtls for decoding base64-encoded keys]

ovpn-cli implements the netlink and RTNL APIs and can thus be integrated
in any script for more automated testing.

Along with the tool, a bunch of scripts are provided that perform basic
functionality tests by means of network namespaces.
These scripts take part to the kselftest automation.

The output of the scripts, which will appear in the kselftest
reports, is a list of steps performed by the scripts plus some
output coming from the execution of `ping`, `iperf` and `ovpn-cli`
itself.
In general it is useful only in case of failure, in order to
understand which step has failed and why.

Please note: since peer sockets are tied to the userspace
process that created them (i.e. exiting the process will result
in closing the socket), every run of ovpn-cli that created
one will go to background and enter pause(), waiting for the
signal which will allow it to terminate.
Termination is accomplished at the end of each script by
issuing a killall command.
