Merge tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core & protocols:

- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.

This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.

- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.

- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.

- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.

- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.

- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.

- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.

- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.

- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.

- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.

- Reduce tcp socket size by one cache line.

- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.

- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.

- Improve xsk generic performances with cache-alignment-oriented
optimizations.

- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.

Driver API:

- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.

- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.

- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.

- Add helper to create, prepare and enable managed clocks.

Device drivers:

- Add Huawei hinic3 PF etherner driver.

- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
controller.

- Add ethernet driver for MaxLinear MxL862xx switches

- Remove parallel-port Ethernet driver.

- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().

ring count retrieval. Also remove the legacy fallback path.

selftests: net: Add kernel selftest for RFC 4884

RFC 4884 extended certain ICMP messages with a length attribute that
encodes the length of the "original datagram" field. This is needed so
that new information could be appended to these messages without
applications thinking that it is part of the "original datagram" field.

In version 5.9, the kernel was extended with two new socket options
(SOL_IP/IP_RECVERR_4884 and SOL_IPV6/IPV6_RECVERR_RFC4884) that allow
user space to retrieve this length which is basically the offset to the
ICMP Extension Structure at the end of the ICMP message. This is
required by user space applications that need to parse the information
contained in the ICMP Extension Structure. For example, the RFC 5837
extension for tracepath.

Add a selftest that verifies correct handling of the RFC 4884 length
field for both IPv4 and IPv6, with and without extension structures,
and validates that malformed extensions are correctly reported as invalid.

For each address family, the test creates:
- a raw socket used to send locally crafted ICMP error packets to the
loopback address, and
- a datagram socket used to receive the encapsulated original datagram
and associated error metadata from the kernel error queue.

ICMP packets are constructed entirely in user space rather than relying
on kernel-generated errors. This allows the test to exercise invalid
scenarios (such as corrupted checksums and incorrect length fields) and
verify that the SO_EE_RFC4884_FLAG_INVALID flag is set as expected.

Merge tag 'net-next-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Replace busylock at the Tx queuing layer with a lockless list.

Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.

- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.

Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.

Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.

- Optimize the NAPI skb cache, make it larger, use it in more paths.

- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).

- Various data structure layout and prefetch optimizations from Eric.

- Remove ktime_get() from the recvmsg() fast path, ktime_get() is
sadly quite expensive on recent AMD machines.

- Extend threaded NAPI polling to allow the kthread busy poll for
packets.

- Make MPTCP use Rx backlog processing. This lowers the lock
pressure, improving the Rx performance.

- Support memcg accounting of MPTCP socket memory.

- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor
fit for modern container workloads, where limits are imposed using
cgroups.

- Improve heuristics for when to kick off AF_UNIX garbage collection.

- Allow users to control TCP SACK compression, and default to 33% of
RTT.

- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid
unnecessarily aggressive rcvbuf growth and overshot when the
connection RTT is low.

- Preserve skb metadata space across skb_push / skb_pull operations.

- Support for IPIP encapsulation in the nftables flowtable offload.

- Support appending IP interface information to ICMP messages (RFC
5837).

- Support setting max record size in TLS (RFC 8449).

- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.

- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.

- Let users configure the number of write buffers in SMC.

- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.

- Some conversions away from the crypto_ahash API, from Eric Biggers.

- Some preparations for slimming down struct page.

- YAML Netlink protocol spec for WireGuard.

- Add a tool on top of YAML Netlink specs/lib for reporting commonly
computed derived statistics and summarized system state.

Driver API:

- Add CAN XL support to the CAN Netlink interface.

- Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics, as
defined by the OPEN Alliance's "Advanced diagnostic features for
100BASE-T1 automotive Ethernet PHYs" specification.

- Add DPLL phase-adjust-gran pin attribute (and implement it in
zl3073x).

- Refactor xfrm_input lock to reduce contention when NIC offloads
IPsec and performs RSS.

- Add info to devlink params whether the current setting is the
default or a user override. Allow resetting back to default.

- Add standard device stats for PSP crypto offload.

- Leverage DSA frame broadcast to implement simple HSR frame
duplication for a lot of switches without dedicated HSR offload.

- Add uAPI defines for 1.6Tbps link modes.

Device drivers:

- Add Motorcomm YT921x gigabit Ethernet switch support.

- Add MUCSE driver for N500/N210 1GbE NIC series.

- Convert drivers to support dedicated ops for timestamping control,
and away from the direct IOCTL handling. While at it support GET
operations for PHY timestamping.

- Add (and convert most drivers to) a dedicated ethtool callback for
reading the Rx ring count.

- Significant refactoring efforts in the STMMAC driver, which
supports Synopsys turn-key MAC IP integrated into a ton of SoCs.

- Broadcom (bnxt):
- support PPS in/out on all pins

ASoC: Updates for v6.19

This is a very large set of updates, as well as some more extensive
cleanup work from Morimto-san we've also added a generic SCDA class
driver for SoundWire devices enabling us to support many chips with
no custom code. There's also a batch of new drivers added for both
SoCs and CODECs.

- Added a SoundWire SCDA generic class driver, pulling in a little
regmap work to support it.
- A *lot* of cleaup and API improvement work from Morimoto-san.
- Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm
drivers.
- Support for Allwinner A523, Mediatek MT8189, Qualcomm QCM2290,
QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806,
TAS5815, TAS5828 and TAS5830.

This also pulls in some gpiolib changes supporting shared GPIOs in the
core there so we can convert some of the ASoC drivers open coding
handling of that to the core functionality.

Merge branch 'selftests-drv-net-convert-gro-and-toeplitz-tests-to-work-for-drivers-in-nipa'

Jakub Kicinski says:

====================
selftests: drv-net: convert GRO and Toeplitz tests to work for drivers in NIPA

Main objective of this series is to convert the gro.sh and toeplitz.sh
tests to be "NIPA-compatible" - meaning make use of the Python env,
which lets us run the tests against either netdevsim or a real device.

The tests seem to have been written with a different flow in mind.
Namely they source different bash "setup" scripts depending on arguments
passed to the test. While I have nothing against the use of bash and
the overall architecture - the existing code needs quite a bit of work
(don't assume MAC/IP addresses, support remote endpoint over SSH).
If I'm the one fixing it, I'd rather convert them to our "simplistic"
Python.

This series rewrites the tests in Python while addressing their
shortcomings. The functionality of running the test over loopback
on a real device is retained but with a different method of invocation
(see the last patch).

Once again we are dealing with a script which run over a variety of
protocols (combination of [ipv4, ipv6, ipip] x [tcp, udp]). The first
4 patches add support for test variants to our scripts. We use the
term "variant" in the same sense as the C kselftest_harness.h -
variant is just a set of static input arguments.

Note that neither GRO nor the Toeplitz test fully passes for me on
any HW I have access to. But this is unrelated to the conversion.
This series is not making any real functional changes to the tests,
it is limited to improving the "test harness" scripts.

selftests: net: relocate gro and toeplitz tests to drivers/net

The GRO test can run on a real device or a veth.
The Toeplitz hash test can only run on a real device.
Move them from net/ to drivers/net/ and drivers/net/hw/ respectively.

There are two scripts which set up the environment for these tests
setup_loopback.sh and setup_veth.sh. Move those scripts to net/lib.
The paths to the setup files are a little ugly but they will be
deleted shortly.

toeplitz_client.sh is not a test in itself, but rather a helper
to send traffic, so add it to TEST_FILES rather than TEST_PROGS.

selftests: af_unix: Add tests for ECONNRESET and EOF semantics

Add selftests to verify and document Linux’s intended behaviour for
UNIX domain sockets (SOCK_STREAM and SOCK_DGRAM) when a peer closes.
The tests verify that:

1. SOCK_STREAM returns EOF when the peer closes normally.
2. SOCK_STREAM returns ECONNRESET if the peer closes with unread data.
3. SOCK_SEQPACKET returns EOF when the peer closes normally.
4. SOCK_SEQPACKET returns ECONNRESET if the peer closes with unread data.
5. SOCK_DGRAM does not return ECONNRESET when the peer closes.

This follows up on review feedback suggesting a selftest to clarify
Linux’s semantics.
