Merge tag 'net-next-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Wrap datapath globals into net_aligned_data, to avoid false sharing

- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container)

- Add SO_INQ and SCM_INQ support to AF_UNIX

- Add SIOCINQ support to AF_VSOCK

- Add TCP_MAXSEG sockopt to MPTCP

- Add IPv6 force_forwarding sysctl to enable forwarding per interface

- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB

- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users

- Convert TCP send queue handling from tasklet to BH workque

- Improve BPF iteration over TCP sockets to see each socket exactly
once

- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code

- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel
NAPI thread when threaded NAPI gets disabled. Previously thread
would stick around until ifdown due to tricky synchronization

- Allow multicast routing to take effect on locally-generated packets

- Add output interface argument for End.X in segment routing

- MCTP: add support for gateway routing, improve bind() handling

- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink

- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed

- Support NUD_PERMANENT for proxy neighbor entries

- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM

- Add sequence numbers to netconsole messages. Unregister
netconsole's console when all net targets are removed. Code
refactoring. Add a number of selftests

- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup

- Support inspecting ref_tracker state via DebugFS

- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links

- Allow providing upcall pid for the 'execute' command in openvswitch

- Remove DCCP support from Netfilter's conntrack

This significantly improved the clarity of the driver facing API.
Migrate the remaining 3 drivers and remove the old way of muxing

====================
net: ethtool: add dedicated RXFH driver callbacks

Andrew asked me to plumb the RXFH header fields configuration
thru to netlink. Before we do that we need to clean up the driver
facing API a little bit. Right now RXFH configuration shares the
callbacks with n-tuple filters. The future of n-tuple filters
is uncertain within netlink. Separate the two for clarity both
of the core code and the driver facing API.

This series adds the new callbacks and converts the initial
handful of drivers. There is 31 more driver patches to come,
then we can stop calling rxnfc in the core for rxfh.

net: ethtool: add dedicated callbacks for getting and setting rxfh fields

We mux multiple calls to the drivers via the .get_nfc and .set_nfc
callbacks. This is slightly inconvenient to the drivers as they
have to de-mux them back. It will also be awkward for netlink code
to construct struct ethtool_rxnfc when it wants to get info about
RX Flow Hash, from the RSS module.

Add dedicated driver callbacks. Create struct ethtool_rxfh_fields
which contains only data relevant to RXFH. Maintain the names of
the fields to avoid having to heavily modify the drivers.

For now support both callbacks, once all drivers are converted
ethtool_*et_rxfh_fields() will stop using the rxnfc callbacks.

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.

- Aeonsemi 10G C45 PHYs driver.

====================
igc: Add support for Frame Preemption

Faizal Rahim says:

Introduce support for the FPE feature in the IGC driver.

The patches aligns with the upstream FPE API:
https://patchwork.kernel.org/project/netdevbpf/cover/20230220122343.1156614-1-vladimir.oltean@nxp.com/
https://patchwork.kernel.org/project/netdevbpf/cover/20230119122705.73054-1-vladimir.oltean@nxp.com/

It builds upon earlier work:
https://patchwork.kernel.org/project/netdevbpf/cover/20220520011538.1098888-1-vinicius.gomes@intel.com/

The patch series adds the following functionalities to the IGC driver:
a) Configure FPE using `ethtool --set-mm`.
b) Display FPE settings via `ethtool --show-mm`.
c) View FPE statistics using `ethtool --include-statistics --show-mm'.
e) Block setting preemptible tc in taprio since it is not supported yet.
Existing code already blocks it in mqprio.

Tested:
Enabled CONFIG_PROVE_LOCKING, CONFIG_DEBUG_ATOMIC_SLEEP, CONFIG_DMA_API_DEBUG, and CONFIG_KASAN
1) selftests
2) netdev down/up cycles
3) suspend/resume cycles
4) fpe verification

No bugs or unusual dmesg logs were observed.
Ran 1), 2) and 3) with and without the patch series, compared dmesg and selftest logs - no differences found.

net: ethtool: mm: extract stmmac verification logic into common library

It appears that stmmac is not the only hardware which requires a
software-driven verification state machine for the MAC Merge layer.

While on the one hand it's good to encourage hardware implementations,
on the other hand it's quite difficult to tolerate multiple drivers
implementing independently fairly non-trivial logic.

Extract the hardware-independent logic from stmmac into library code and
put it in ethtool. Name the state structure "mmsv" for MAC Merge
Software Verification. Let this expose an operations structure for
executing the hardware stuff: sync hardware with the tx_active boolean
(result of verification process), enable/disable the pMAC, send mPackets,
notify library of external events (reception of mPackets), as well as
link state changes.

Note that it is assumed that the external events are received in hardirq
context. If they are not, it is probably a good idea to disable hardirqs
when calling ethtool_mmsv_event_handle(), because the library does not
do so.

Also, the MM software verification process has no business with the
tx_min_frag_size, that is all the driver's to handle.

net: ethtool: Adjust exactly ETH_GSTRING_LEN-long stats to use memcpy

Many drivers populate the stats buffer using C-String based APIs (e.g.
ethtool_sprintf() and ethtool_puts()), usually when building up the
list of stats individually (i.e. with a for() loop). This, however,
requires that the source strings be populated in such a way as to have
a terminating NUL byte in the source.

Other drivers populate the stats buffer directly using one big memcpy()
of an entire array of strings. No NUL termination is needed here, as the
bytes are being directly passed through. Yet others will build up the
stats buffer individually, but also use memcpy(). This, too, does not
need NUL termination of the source strings.

However, there are cases where the strings that populate the
source stats strings are exactly ETH_GSTRING_LEN long, and GCC
15's -Wunterminated-string-initialization option complains that the
trailing NUL byte has been truncated. This situation is fine only if the
driver is using the memcpy() approach. If the C-String APIs are used,
the destination string name will have its final byte truncated by the
required trailing NUL byte applied by the C-string API.

For drivers that are already using memcpy() but have initializers that
truncate the NUL terminator, mark their source strings as __nonstring to
silence the GCC warnings.

For drivers that have initializers that truncate the NUL terminator and
are using the C-String APIs, switch to memcpy() to avoid destination
string truncation and mark their source strings as __nonstring to silence
the GCC warnings. (Also introduce ethtool_cpy() as a helper to make this
an easy replacement).

Specifically the following warnings were investigated and addressed:
