Corrected "sages" to "messages" in the bitmap allocation description.
Fixed "competed" to "completed" in the recv path datagram handling section.
Corrected "privatee" to "private" in the multipath RDS section.
Fixed "mutlipath" to "multipath" in the transport capabilities description.
These changes improve documentation clarity and maintain consistency.

4) Refactor migration setup during cloning. This was

From Chiachang Wang.
5) Validate assignment of maximal possible SEQ number.
Prevent from setting to the maximum sequrnce number
as this would cause for traffic drop.

pull-request: can-next 2025-05-22
this is a pull request of 22 patches for net-next/main.
The series by Biju Das contains 19 patches and adds RZ/G3E CANFD
support to the rcar_canfd driver.
The patch by Vincent Mailhol adds a struct data_bittiming_params to
group FD parameters as a preparation patch for CAN-XL support.
Felix Maurer's patch imports tst-filter from can-tests into the kernel
self tests and Vincent Mailhol adds support for physical CAN
interfaces.

Multi-PTP source support within a network topology has been merged,
but the hardware timestamp source is not yet exposed to users.
Currently, users only see the PTP index, which does not indicate
whether the timestamp comes from a PHY or a MAC.
Add support for reporting the hwtstamp source using a
hwtstamp-source field, alongside hwtstamp-phyindex, to describe
the origin of the hardware timestamp.
Remove HWTSTAMP_SOURCE_UNSPEC enum value as it is not used at all.

This is [1/3] part of hinic3 Ethernet driver initial submission.
With this patch hinic3 is a valid kernel module but non-functional
driver.
The driver parts contained in this patch:
Module initialization.
PCI driver registration but with empty id_table.
Auxiliary driver registration.
Net device_ops registration but open/stop are empty stubs.
tx/rx logic.
All major data structures of the driver are fully introduced with the
code that uses them but without their initialization code that requires
management interface with the hw.

All attribute sets and messages are prefixed with tc-.
The C codegen also adds the family name to all structs.
We end up with names like struct tc_tc_act_attrs.
Remove the tc- prefixes to shorten the names.
This should not impact Python as the attr set names
are never exposed to user, they are only used to refer
to things internally, in the encoder / decoder.

There is a define in the uAPI header called tc_gen which expands
to the "generic" TC action fields. This helps other actions include
the base fields without having to deal with nested structs.
A couple of actions (sample, gact) do not define extra fields,
so the spec used a common tc-gen struct for both of them.
Unfortunately this struct does not exist in C. Let's use gact's
(generic act's) struct for basic actions.

tc-act-stats-attrs and tca-stats-attrs are almost identical.
The only difference is that the latter has sub-message decoding

which supports up to six channels.
The CAN-FD module on RZ/G3E is very similar to the one on both R-Car V4H

* No external clock, but instead has ram clock.
* Support up to 6 channels.

Introduce 'firmware-name' property to allow end-users and/or integrators
to decide which usecase-specific firmware to run on the WCN7850 platform.
This is necessary due to resource limitations such as memory capacity and
CPU capability, or performance and power optimization for different
application scenarios.
Two firmwares are supported: 'WCN7850/hw2.0' and 'WCN7850/hw2.0/ncm825'.
The former is the default firmware, suitable for most WiFi 7 STA
functions. The latter adds support for commercial-quality SAP and
optimizes power consumption for IoT applications.

Pull x86 ITS mitigation from Dave Hansen:
"Mitigate Indirect Target Selection (ITS) issue.
I'd describe this one as a good old CPU bug where the behavior is
_obviously_ wrong, but since it just results in bad predictions it
wasn't wrong enough to notice. Well, the researchers noticed and also
realized that thus bug undermined a bunch of existing indirect branch
mitigations.
Thus the unusually wide impact on this one. Details:
ITS is a bug in some Intel CPUs that affects indirect branches
including RETs in the first half of a cacheline. Due to ITS such
branches may get wrongly predicted to a target of (direct or indirect)
branch that is located in the second half of a cacheline. Researchers
at VUSec found this behavior and reported to Intel.
Affected processors:
- Cascade Lake, Cooper Lake, Whiskey Lake V, Coffee Lake R, Comet
Lake, Ice Lake, Tiger Lake and Rocket Lake.
Scope of impact:
- Guest/host isolation:
When eIBRS is used for guest/host isolation, the indirect branches
in the VMM may still be predicted with targets corresponding to
direct branches in the guest.
- Intra-mode using cBPF:
cBPF can be used to poison the branch history to exploit ITS.
Realigning the indirect branches and RETs mitigates this attack
vector.
- User/kernel:
With eIBRS enabled user/kernel isolation is *not* impacted by ITS.
- Indirect Branch Prediction Barrier (IBPB):
Due to this bug indirect branches may be predicted with targets
corresponding to direct branches which were executed prior to IBPB.
This will be fixed in the microcode.
Mitigation:
As indirect branches in the first half of cacheline are affected, the
mitigation is to replace those indirect branches with a call to thunk that
is aligned to the second half of the cacheline.
RETs that take prediction from RSB are not affected, but they may be
affected by RSB-underflow condition. So, RETs in the first half of
cacheline are also patched to a return thunk that executes the RET aligned
to second half of cacheline"

Ice Lake generation CPUs are not affected by guest/host isolation part of
ITS. If a user is only concerned about KVM guests, they can now choose a
new cmdline option "vmexit" that will not deploy the ITS mitigation when
CPU is not affected by guest/host isolation. This saves the performance
overhead of ITS mitigation on Ice Lake gen CPUs.
When "vmexit" option selected, if the CPU is affected by ITS guest/host
isolation, the default ITS mitigation is deployed.

Indirect Target Selection (ITS) is a bug in some pre-ADL Intel CPUs with
eIBRS. It affects prediction of indirect branch and RETs in the
lower half of cacheline. Due to ITS such branches may get wrongly predicted
to a target of (direct or indirect) branch that is located in the upper
half of the cacheline.
Scope of impact
===============
Guest/host isolation
--------------------
When eIBRS is used for guest/host isolation, the indirect branches in the
VMM may still be predicted with targets corresponding to branches in the
guest.
Intra-mode
----------
cBPF or other native gadgets can be used for intra-mode training and
disclosure using ITS.
User/kernel isolation
---------------------
When eIBRS is enabled user/kernel isolation is not impacted.
Indirect Branch Prediction Barrier (IBPB)
-----------------------------------------
After an IBPB, indirect branches may be predicted with targets
corresponding to direct branches which were executed prior to IBPB. This is
mitigated by a microcode update.
Add cmdline parameter indirect_target_selection=off|on|force to control the
mitigation to relocate the affected branches to an ITS-safe thunk i.e.
located in the upper half of cacheline. Also add the sysfs reporting.
When retpoline mitigation is deployed, ITS safe-thunks are not needed,
because retpoline sequence is already ITS-safe. Similarly, when call depth
tracking (CDT) mitigation is deployed (retbleed=stuff), ITS safe return
thunk is not used, as CDT prevents RSB-underflow.
To not overcomplicate things, ITS mitigation is not supported with
spectre-v2 lfence;jmp mitigation. Moreover, it is less practical to deploy
lfence;jmp mitigation on ITS affected parts anyways.

uAPI doesn't define structs for the SNMP counters, just enums to index
them as arrays. Switch to the same representation in the spec. C codegen
will soon need all the struct types to actually exist.
Note that the existing definition was broken, anyway, as the first
member should be the number of counters reported.
