A common task for most drivers is to remember the user-set CPU affinity
to its IRQs. On each netdev reset, the driver should re-assign the user's
settings to the IRQs. Unify this task across all drivers by moving the CPU
affinity to napi->config.
However, to move the CPU affinity to core, we also need to move aRFS
rmap management since aRFS uses its own IRQ notifiers.
For the aRFS, add a new netdev flag "rx_cpu_rmap_auto". Drivers supporting
aRFS should set the flag via netif_enable_cpu_rmap() and core will allocate
and manage the aRFS rmaps. Freeing the rmap is also done by core when the
netdev is freed. For better IRQ affinity management, move the IRQ rmap
notifier inside the napi_struct and add new notify.notify and
notify.release functions: netif_irq_cpu_rmap_notify() and
netif_napi_affinity_release().
Now we have the aRFS rmap management in core, add CPU affinity mask to
napi_config. To delegate the CPU affinity management to the core, drivers
must:
1 - set the new netdev flag "irq_affinity_auto":
netif_enable_irq_affinity(netdev)
2 - create the napi with persistent config:
netif_napi_add_config()
3 - bind an IRQ to the napi instance: netif_napi_set_irq()
the core will then make sure to use re-assign affinity to the napi's
IRQ.
The default IRQ mask is set to one cpu starting from the closest NUMA.

Yong-Hao Zou mentioned that linux was not strict as other OS in 3WHS,
for flows using TCP TS option (RFC 7323)
As hinted by an old comment in tcp_check_req(),
we can check the TSEcr value in the incoming packet corresponds
to one of the SYNACK TSval values we have sent.
In this patch, I record the oldest and most recent values
that SYNACK packets have used.
Send a challenge ACK if we receive a TSEcr outside
of this range, and increase a new SNMP counter.
nstat -az | grep TSEcrRejected
TcpExtTSEcrRejected 0 0.0
Due to TCP fastopen implementation, do not apply yet these checks
for fastopen flows.
v2: No longer use req->num_timeout, but treq->snt_tsval_first
to detect when first SYNACK is prepared. This means
we make sure to not send an initial zero TSval.
Make sure MPTCP and TCP selftests are passing.
Change MIB name to TcpExtTSEcrRejected

Add dtschema for the MDIO controller found in the RTL9300 Ethernet
switch. The controller is slightly unusual in that direct MDIO
communication is not possible. We model the MDIO controller with the
MDIO buses as child nodes and the PHYs as children of the buses. The
mapping of switch port number to MDIO bus/addr requires the
ethernet-ports sibling to provide the mapping via the phy-handle
property.

====================
pull-request: can-next 2025-02-19
this is a pull request of 12 patches for net-next/master.
The first 4 patches are by Krzysztof Kozlowski and simplify the c_can
driver's c_can_plat_probe() function.
Ciprian Marian Costea contributes 3 patches to add S32G2/S32G3 support
to the flexcan driver.
Ruffalo Lavoisier's patch removes a duplicated word from the mcp251xfd
DT bindings documentation.
Oleksij Rempel extends the J1939 documentation.
The next patch is by Oliver Hartkopp and adds access for the Remote
Request Substitution bit in CAN-XL frames.
Henrik Brix Andersen's patch for the gs_usb driver adds support for
the CANnectivity firmware.
The last patch is by Robin van der Gracht and removes a duplicated
setup of RX FIFO in the rockchip_canfd driver.

Add S32G2/S32G3 SoCs compatible strings.
A particularity for these SoCs is the presence of separate interrupts for
state change, bus errors, MBs 0-7 and MBs 8-127 respectively.
Increase maxItems of 'interrupts' to 4 for S32G based SoCs and keep the
same restriction for other SoCs.
Also, as part of this commit, move the 'allOf' after the required
properties to make the documentation easier to read.

Could be just me, but I had to pause and double check that the Tx csum
counter in qstat should include GSO'd packets. GSO pretty much implies
csum so one could possibly interpret the csum counter as pure csum offload.
But the counters are based on virtio:
[tx_needs_csum]
The number of packets which require checksum calculation by the device.
[rx_needs_csum]
The number of packets with VIRTIO_NET_HDR_F_NEEDS_CSUM.
and VIRTIO_NET_HDR_F_NEEDS_CSUM gets set on GSO packets virtio sends.
Clarify this in the spec to avoid any confusion.

Here is a driver core new api for 6.14-rc3 that is being added to allow
platform devices from stop being abused. It adds a new "faux_device"
structure and bus and api to allow almost a straight or simpler
conversion from platform devices that were not really a platform device.
It also comes with a binding for rust, with an example driver in rust
showing how it's used.
I'm adding this now so that the patches that convert the different
drivers and subsystems can all start flowing into linux-next now through
their different development trees, in time for 6.15-rc1. We have a
number that are already reviewed and tested, but adding those
conversions now doesn't seem right. For now, no one is using this, and
it passes all build tests from 0-day and linux-next, so all should be
good.

Current release - regressions:
- eth:
- stmmac: correct Rx buffer layout when SPH is enabled
- iavf: fix a locking bug in an error path
- rxrpc: fix alteration of headers whilst zerocopy pending
- s390/qeth: move netif_napi_add_tx() and napi_enable() from under BH
- Revert "netfilter: flowtable: teardown flow if cached mtu is stale"
Current release - new code bugs:
- rxrpc: fix ipv6 path MTU discovery, only ipv4 worked
- pse-pd: fix deadlock in current limit functions
Previous releases - regressions:
- rtnetlink: fix netns refleak with rtnl_setlink()
- wifi: brcmfmac: use random seed flag for BCM4355 and BCM4364

Many drivers abuse the platform driver/bus system as it provides a
simple way to create and bind a device to a driver-specific set of
probe/release functions. Instead of doing that, and wasting all of the
memory associated with a platform device, here is a "faux" bus that
can be used instead.
