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

- Disallow multiple packet duplications in the queuing layer

- Prevent use of deprecated iptables code on PREEMPT_RT

Driver API:

- Support RSS and hashing configuration over ethtool Netlink

- Add dedicated ethtool callbacks for getting and setting hashing
fields

net/mlx5e: Fix potential deadlock by deferring RX timeout recovery

mlx5e_reporter_rx_timeout() is currently invoked synchronously
in the driver's open error flow. This causes the thread holding
priv->state_lock to attempt acquiring the devlink lock, which
can result in a circular dependency with other devlink operations.

For example:

- Devlink health diagnose flow:
- __devlink_nl_pre_doit() acquires the devlink lock.
- devlink_nl_health_reporter_diagnose_doit() invokes the
driver's diagnose callback.
- mlx5e_rx_reporter_diagnose() then attempts to acquire
priv->state_lock.

- Driver open flow:
- mlx5e_open() acquires priv->state_lock.
- If an error occurs, devlink_health_reporter may be called,
attempting to acquire the devlink lock.

To prevent this circular locking scenario, defer the RX timeout
recovery by scheduling it via a workqueue. This ensures that the
recovery work acquires locks in a consistent order: first the
devlink lock, then priv->state_lock.

Additionally, make the recovery work acquire the netdev instance
lock to safely synchronize with the open/close channel flows,
similar to mlx5e_tx_timeout_work. Repeatedly attempt to acquire
the netdev instance lock until it is taken or the target RQ is no
longer active, as indicated by the MLX5E_STATE_CHANNELS_ACTIVE bit.

====================
net/mlx5e: Add support for PCIe congestion events

Dragos says:

PCIe congestion events are events generated by the firmware when the
device side has sustained PCIe inbound or outbound traffic above
certain thresholds. The high and low threshold are hysteresis thresholds
to prevent flapping: once the high threshold has been reached, a low
threshold event will be triggered only after the bandwidth usage went
below the low threshold.

This series adds support for receiving and exposing such events as
ethtool counters.

2 new pairs of counters are exposed: pci_bw_in/outbound_high/low. These
should help the user understand if the device PCI is under pressure.

Planned followup patches:
- Allow configuration of thresholds through devlink.
- Add ethtool counter for wakeups which did not result in any state
change.

net/mlx5e: Remove unused VLAN insertion logic in TX path

The VLAN insertion capability (`wqe_vlan_insert`) was never enabled on
all mlx5 devices. When VLAN TX offload is advertised but this
capability is not supported, the driver uses inline headers to insert
the VLAN tag.

To support this, the driver used to set the
`MLX5E_SQ_STATE_VLAN_NEED_L2_INLINE` bit to enforce L2 inline mode
when `wqe_vlan_insert` was not supported. Since the capability is
disabled on all devices, this logic was always active, and the SQ flag
has become redundant. L2 inline is enforced unconditionally for
VLAN-tagged packets.

The `skb_vlan_tag_present()` check in the else-if block of
`mlx5e_sq_xmit_wqe()` is never true by this point in the TX flow,
as the VLAN tag has already been inserted by the driver using inline
headers. As a result, this code is never executed.

Remove the redundant SQ state, dead VLAN insertion code block, and
related logic.

====================
net/mlx5e: Add support for devmem and io_uring TCP zero-copy

This series adds support for zerocopy rx TCP with devmem and io_uring
for ConnectX7 NICs and above. For performance reasons and simplicity
HW-GRO will also be turned on when header-data split mode is on.

Performance
===========

Test setup:

* CPU: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz (single NUMA)
* NIC: ConnectX7
* Benchmarking tool: kperf [0]
* Single TCP flow
* Test duration: 60s

With application thread and interrupts pinned to the *same* core:

|------+-----------+----------|
| MTU | epoll | io_uring |
|------+-----------+----------|
| 1500 | 61.6 Gbps | 114 Gbps |
| 4096 | 69.3 Gbps | 151 Gbps |
| 9000 | 67.8 Gbps | 187 Gbps |
|------+-----------+----------|

The CPU usage for io_uring is 95%.

Reproduction steps for io_uring:

server --no-daemon -a 2001:db8::1 --no-memcmp --iou --iou_sendzc \
--iou_zcrx --iou_dev_name eth2 --iou_zcrx_queue_id 2

server --no-daemon -a 2001:db8::2 --no-memcmp --iou --iou_sendzc

client --src 2001:db8::2 --dst 2001:db8::1 \
--msg-zerocopy -t 60 --cpu-min=2 --cpu-max=2

Patch overview:
================

First, a netmem API for skb_can_coalesce is added to the core to be able
to do skb fragment coalescing on netmems.

The next patches introduce some cleanups in the internal SHAMPO code and
improvements to hw gro capability checks in FW.

A separate page_pool is introduced for headers, to be used only when
the rxq has a memory provider.

Then the driver is converted to use the netmem API and to allow support
for unreadable netmem page pool.

The queue management ops are implemented.

Finally, the tcp-data-split ring parameter is exposed.

net/mlx5e: Convert over to netmem

mlx5e_page_frag holds the physical page itself, to naturally support
zc page pools, remove physical page reference from mlx5 and replace it
with netmem_ref, to avoid internal handling in mlx5 for net_iov backed
pages.

SHAMPO can issue packets that are not split into header and data. These
packets will be dropped if the data part resides in a net_iov as the
driver can't read into this area.

No performance degradation observed.
