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

- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP

- Number of code moves to help the compiler with inlining. Avoid
output arguments for returning drop reason where possible

- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints

- Remove the rtnl_lock use from IP Multicast Routing

- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two

- Report TCP delayed ack timer information via socket diag

- Add ip_local_port_step_width sysctl to allow distributing the
randomly selected ports more evenly throughout the allowed space

- Add support for per-route tunsrc in IPv6 segment routing

- Start work of switching sockopt handling to iov_iter

- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up

- Support MSG_EOR in MPTCP

- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage

- Remove UDP-Lite support (as announced in 2023)

- Remove support for building IPv6 as a module. Remove the now
unnecessary function calling indirection

Cross-tree stuff:

- Move Michael MIC code from generic crypto into wireless, it's
considered insecure but some WiFi networks still need it

Netfilter:

- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.

Florian W reports this gets us ~13% higher packet rate

- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex

- Add more opinionated input validation to lower security exposure

- Make IPVS hash tables to be per-netns and resizable

Wireless:

- Finished assoc frame encryption/EPPKE/802.1X-over-auth

- Radar detection improvements

- Add 6 GHz incumbent signal detection APIs

- Multi-link support for FILS, probe response templates and client
probing

- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware

Driver API:

- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs

- Add standard counters for reporting pause storm events (implement
in mlx5 and fbnic)

- Add configuration API for completion writeback buffering (implement
in mana)

- Support driver-initiated change of RSS context sizes

- Support DPLL monitoring input frequency (implement in zl3073x)

- Support per-port resources in devlink (implement in mlx5)

Misc:

- Expand the YAML spec for Netfilter

Cosmin Ratiu says:

====================
macsec: Add support for VLAN filtering in offload mode

This short series adds support for VLANs in MACsec devices when offload
mode is enabled. This allows VLAN netdevs on top of MACsec netdevs to
function, which accidentally used to be the case in the past, but was
broken. This series adds back proper support.

As part of this, the existing nsim-only MACsec offload tests were
translated to Python so they can run against real HW and new
traffic-based tests were added for VLAN filter propagation, since
there's currently no uAPI to check VLAN filters.

selftests: Add MACsec VLAN propagation traffic test

Add VLAN filter propagation tests through offloaded MACsec devices via
actual traffic.

The tests create MACsec tunnels with matching SAs on both endpoints,
stack VLANs on top, and verify connectivity with ping. Covered:
- Offloaded MACsec with VLAN (filters propagate to HW)
- Software MACsec with VLAN (no HW filter propagation)
- Offload on/off toggle and verifying traffic still works

On netdevsim this makes use of the VLAN filter debugfs file to actually
validate that filters are applied/removed correctly.
On real hardware the traffic should validate actual VLAN filter
propagation.

framework so tests can run against both netdevsim (default) and real

encryption, add that to the tests.

Netdevsim-specific limit checks (max SecY, max RX SC) were moved into
separate test cases to avoid failures on real hardware.

Merge tag 'net-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Improve drop account scalability on NUMA hosts for RAW and UDP
sockets and the backlog, almost doubling the Pps capacity under DoS

- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance
by an additional 50%, even more under extreme conditions

- Add support for PSP encryption of TCP connections; this mechanism
has some similarities with IPsec and TLS, but offers superior HW
offloads capabilities

- Ongoing work to support Accurate ECN for TCP. AccECN allows more
than one congestion notification signal per RTT and is a building
block for Low Latency, Low Loss, and Scalable Throughput (L4S)

- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath

- Refactor skb deferral free to better scale on large multi-NUMA
hosts, this improves TCP and UDP RX performances significantly on
such HW

- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds

- Improve handling of setups with a large number of nexthop, making
dump operating scaling linearly and avoiding unneeded
synchronize_rcu() on delete

- Improve bridge handling of VLAN FDB, storing a single entry per
bridge instead of one entry per port; this makes the dump order of
magnitude faster on large switches

- Restore IP ID correctly for encapsulated packets at GSO
segmentation time, allowing GRO to merge packets in more scenarios

- Improve netfilter matching performance on large sets

- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting
recent TCP autotuning changes

- Allow bridges to redirect to a backup port when the bridge port is
administratively down

- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups

- Add RCU safety to dst->dev, closing a lot of possible races

- A significant crypto library API for SCTP, MPTCP and IPv6 SR,
reducing code duplication

- Supports pulling data from an skb frag into the linear area of an
XDP buffer

Things we sprinkled into general kernel code:

- Generate netlink documentation from YAML using an integrated YAML
parser

Driver API:

- Support using IPv6 Flow Label in Rx hash computation and RSS queue
selection

- Introduce API for fetching the DMA device for a given queue,
allowing TCP zerocopy RX on more H/W setups

- Make XDP helpers compatible with unreadable memory, allowing more
easily building DevMem-enabled drivers with a unified XDP/skbs
datapath

- Add a new dedicated ethtool callback enabling drivers to provide
the number of RX rings directly, improving efficiency and clarity
in RX ring queries and RSS configuration

- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause

- Support for DPLL phase offset exponential moving average,
controlling the average smoothing factor

Device drivers:

- Add a new Huawei driver for 3rd gen NIC (hinic3)

- Add a new SpacemiT driver for K1 ethernet MAC

- Add a generic abstraction for shared memory communication
devices (dibps)

- Ethernet high-speed NICs:
- nVidia/Mellanox:

issues
- support adjacent functions, allowing them to delegate their
SR-IOV VFs to sibling PFs
- support RSS for IPSec offload
- support exposing raw cycle counters in PTP and mlx5
- support for disabling host PFs.

====================
psp: add a kselftest suite and netdevsim implementation

Add a basic test suite for drivers that support PSP. Also, add a PSP
implementation in the netdevsim driver.

The netdevsim implementation does encapsulation and decapsulation of
PSP packets, but no crypto.

The tests cover the basic usage of the uapi, and demonstrate key
exchange and connection setup. The tests and netdevsim support IPv4
and IPv6. Here is an example run on a system with a CX7 NIC.
