Use ynl-gen to generate the UAPI header for WireGuard.
The cosmetic changes in this patch confirms that the spec is aligned
with the implementation. By using the generated version, it ensures
that they stay in sync.
Changes in the generated header:
* Trivial header guard rename.
* Trivial white space changes.
* Trivial comment changes.
* Precompute bitflags in ynl-gen (see [1]).
* Drop __*_F_ALL constants (see [1]).

Move the wg*_flag enums, so they are defined above the attribute set
enums, where ynl-gen would place them.
This is an incremental step towards adopting an UAPI header generated
by ynl-gen. This is split out to keep the patches readable.

This patch adds a near[1] complete YNL specification for WireGuard,
documenting the protocol in a machine-readable format, rather than
comments in wireguard.h, and eases usage from C and non-C programming
languages alike.
The generated C library will be featured in a later patch, so in
this patch I will use the in-kernel python client for examples.
This makes the documentation in the UAPI header redundant, it is
therefore removed. The in-line documentation in the spec is based
on the existing comment in wireguard.h, and once released it will
be available in the kernel documentation at:
https://docs.kernel.org/netlink/specs/wireguard.html
(until then run: make htmldocs)
Generate wireguard.rst from this spec:
$ make -C tools/net/ynl/generated/ wireguard.rst
Query wireguard interface through pyynl:
$ sudo ./tools/net/ynl/pyynl/cli.py --family wireguard \
--dump get-device \
--json '{"ifindex":3}'
[{'fwmark': 0,
'ifindex': 3,
'ifname': 'wg-test',
'listen-port': 54318,
'peers': [{0: {'allowedips': [{0: {'cidr-mask': 0,
'family': 2,
'ipaddr': '0.0.0.0'}},
{0: {'cidr-mask': 0,
'family': 10,
'ipaddr': '::'}}],
'endpoint': b'[...]',
'last-handshake-time': {'nsec': 42, 'sec': 42},
'persistent-keepalive-interval': 42,
'preshared-key': '[...]',
'protocol-version': 1,
'public-key': '[...]',
'rx-bytes': 42,
'tx-bytes': 42}}],
'private-key': '[...]',
'public-key': '[...]'}]
Add another allowed IP prefix:
$ sudo ./tools/net/ynl/pyynl/cli.py --family wireguard \
--do set-device --json '{"ifindex":3,"peers":[
{"public-key":"6a df b1 83 a4 ..","allowedips":[
{"cidr-mask":0,"family":10,"ipaddr":"::"}]}]}'
[1] As can be seen above, the "endpoint" is only dumped as binary data,
as it can't be fully described in YNL. It's either a struct
sockaddr_in or struct sockaddr_in6 depending on the attribute length.

====================
Netfilter updates for net-next
The following batch contains Netfilter updates for net-next:
0) Add sanity check for maximum encapsulations in bridge vlan,
reported by the new AI robot.
1) Move the flowtable path discovery code to its own file, the
nft_flow_offload.c mixes the nf_tables evaluation with the path
discovery logic, just split this in two for clarity.
2) Consolidate flowtable xmit path by using dev_queue_xmit() and the
real device behind the layer 2 vlan/pppoe device. This allows to
inline encapsulation. After this update, hw_ifidx can be removed
since both ifidx and hw_ifidx now point to the same device.
3) Support for IPIP encapsulation in the flowtable, extend selftest
to cover for this new layer 3 offload, from Lorenzo Bianconi.
4) Push down the skb into the conncount API to fix duplicates in the
conncount list for packets with non-confirmed conntrack entries,
this is due to an optimization introduced in d265929930e2
("netfilter: nf_conncount: reduce unnecessary GC").
From Fernando Fernandez Mancera.
5) In conncount, disable BH when performing garbage collection
to consolidate existing behaviour in the conncount API, also
from Fernando.
6) A matching packet with a confirmed conntrack invokes GC if
conncount reaches the limit in an attempt to release slots.
This allows the existing extensions to be used for real conntrack
counting, not just limiting new connections, from Fernando.
7) Support for updating ct count objects in nf_tables, from Fernando.
8) Extend nft_flowtables.sh selftest to send IPv6 TCP traffic,
from Lorenzo Bianconi.
9) Fixes for UAPI kernel-doc documentation, from Randy Dunlap.

The XPCS driver was mangling the PMA identifier as the original code
appears to have been focused on just capturing the OUI. Rather than store a
mangled ID it is better to work with the actual PMA ID and instead just
mask out the values that don't apply rather than shifting them and
reordering them as you still don't get the original OUI for the NIC without
having to bitswap the values as per the definition of the layout in IEEE
802.3-2022 22.2.4.3.1.
By laying it out as it was in the hardware it is also less likely for us to
have an unintentional collision as the enum values will occupy the revision
number area while the OUI occupies the upper 22 bits.

With this change we are adding support for 25G, 50G, and 100G interface
types to the XPCS driver. This had supposedly been enabled with the
addition of XLGMII but I don't see any capability for configuration there
so I suspect it may need to be refactored in the future.
With this change we can enable the XPCS driver with the selected interface
and it should be able to detect link, speed, and report the link status to
the phylink interface.

The 2.5G and 5G values are not consistent between the PCS CTRL1 and PMA
CTRL1 values. In order to avoid confusion between the two I am updating the
values to include "PMA" in the name similar to values used in similar

To avoid breaking UAPI I have retained the original macros and just defined
them as the new PMA based defines.

When the TMS is switched on, the node uses PWM (Pulse Width
Modulation) during the data phase instead of the classic NRZ (Non
Return to Zero) encoding.
PWM is configured by three parameters:
- PWMS: Pulse Width Modulation Short phase
- PWML: Pulse Width Modulation Long phase
- PWMO: Pulse Width Modulation Offset time
For each of these parameters, define three IFLA symbols:
- IFLA_CAN_PWM_PWM*_MIN: the minimum allowed value.
- IFLA_CAN_PWM_PWM*_MAX: the maximum allowed value.
- IFLA_CAN_PWM_PWM*: the runtime value.
This results in a total of nine IFLA symbols which are all nested in a
parent IFLA_CAN_XL_PWM symbol.
IFLA_CAN_PWM_PWM*_MIN and IFLA_CAN_PWM_PWM*_MAX define the range of
allowed values and will match the value statically configured by the
device in struct can_pwm_const.
IFLA_CAN_PWM_PWM* match the runtime values stored in struct can_pwm.
Those parameters may only be configured when the tms mode is on. If
the PWMS, PWML and PWMO parameters are provided, check that all the
needed parameters are present using can_validate_pwm(), then check
their value using can_validate_pwm_bittiming(). PWMO defaults to zero
if omitted. Otherwise, if CAN_CTRLMODE_XL_TMS is true but none of the
PWM parameters are provided, calculate them using can_calc_pwm().

The Transceiver Mode Switching (TMS) indicates whether the CAN XL
controller shall use the PWM or NRZ encoding during the data phase.
The term "transceiver mode switching" is used in both ISO 11898-1 and
CiA 612-2 (although only the latter one uses the abbreviation TMS). We
adopt the same naming convention here for consistency.
Add the CAN_CTRLMODE_XL_TMS flag to the list of the CAN control modes.
Add can_validate_xl_flags() to check the coherency of the TMS flag.
That function will be reused in upcoming changes to validate the other
CAN XL flags.

CAN XL uses bittiming parameters different from Classical CAN and CAN
FD. Thus, all the data bittiming parameters, including TDC, need to be
duplicated for CAN XL.
Add the CAN XL netlink interface for all the features which are common
with CAN FD. Any new CAN XL specific features are added later on.
The first time CAN XL is activated, the MTU is set by default to
CANXL_MAX_MTU. The user may then configure a custom MTU within the
CANXL_MIN_MTU to CANXL_MAX_MTU range, in which case, the custom MTU
value will be kept as long as CAN XL remains active.

ISO 11898-1:2024 adds a new restricted operation mode. This mode is
added as a mandatory feature for nodes which support CAN XL and is
retrofitted as optional for legacy nodes (i.e. the ones which only
support Classical CAN and CAN FD).
The restricted operation mode is nearly the same as the listen only
mode: the node can not send data frames or remote frames and can not
send dominant bits if an error occurs. The only exception is that the
node shall still send the acknowledgment bit. A second niche exception
is that the node may still send a data frame containing a time
reference message if the node is a primary time provider, but because
the time provider feature is not yet implemented in the kernel, this
second exception is not relevant to us at the moment.
Add the CAN_CTRLMODE_RESTRICTED control mode flag and update the
can_dev_dropped_skb() helper function accordingly.
Finally, bail out if both CAN_CTRLMODE_LISTENONLY and
CAN_CTRLMODE_RESTRICTED are provided.

Support querying and resetting to default param values.
Introduce two new devlink netlink attrs:
DEVLINK_ATTR_PARAM_VALUE_DEFAULT and
DEVLINK_ATTR_PARAM_RESET_DEFAULT. The former is used to contain an
optional parameter value inside of the param_value nested
attribute. The latter is used in param-set requests from userspace to
indicate that the driver should reset the param to its default value.
To implement this, two new functions are added to the devlink driver
api: devlink_param::get_default() and
devlink_param::reset_default(). These callbacks allow drivers to
implement default param actions for runtime and permanent cmodes. For
driverinit params, the core latches the last value set by a driver via
devl_param_driverinit_value_set(), and uses that as the default value
for a param.
Because default parameter values are optional, it would be impossible
to discern whether or not a param of type bool has default value of
false or not provided if the default value is encoded using a netlink
flag type. For this reason, when a DEVLINK_PARAM_TYPE_BOOL has an
associated default value, the default value is encoded using a u8
type.

And expand it to encompass all pressure pads.
Definition: "pressure pad" as used here as includes all touchpads that
use physical pressure to convert to click, without physical hinges. Also
called haptic touchpads in general parlance, Synaptics calls them
ForcePads.
Most (all?) pressure pads are currently advertised as
INPUT_PROP_BUTTONPAD. The suggestion to identify them as pressure pads
by defining the resolution on ABS_MT_PRESSURE has been in the docs since
commit 20ccc8dd38a3 ("Documentation: input: define
ABS_PRESSURE/ABS_MT_PRESSURE resolution as grams") but few devices
provide this information.
In userspace it's thus impossible to determine whether a device is a
true pressure pad (pressure equals pressure) or a normal clickpad with
(pressure equals finger size).
Commit 7075ae4ac9db ("Input: add INPUT_PROP_HAPTIC_TOUCHPAD") introduces
INPUT_PROP_HAPTIC_TOUCHPAD but restricted it to those touchpads that
have support for userspace-controlled effects. Let's expand and rename
that definition to include all pressure pad touchpads since those that
do support FF effects can be identified by the presence of the
FF_HAPTIC bit.
This means:
- clickpad: INPUT_PROP_BUTTONPAD
- pressurepad: INPUT_PROP_BUTTONPAD + INPUT_PROP_PRESSUREPAD
- pressurepad with configurable haptics:
INPUT_PROP_BUTTONPAD + INPUT_PROP_PRESSUREPAD + FF_HAPTIC

grab_requested_mnt_ns was changed to return error codes on failure, but
its callers were not updated to check for error pointers, still checking
only for a NULL return value.
This commit updates the callers to use IS_ERR() or IS_ERR_OR_NULL() and
PTR_ERR() to correctly check for and propagate errors.
This also makes sure that the logic actually works and mount namespace
file descriptors can be used to refere to mounts.
Christian Brauner <brauner@kernel.org> says:
Rework the patch to be more ergonomic and in line with our overall error
handling patterns.

Adds DEVLINK_ESWITCH_MODE_SWITCHDEV_INACTIVE attribute to UAPI and
documentation.
Before having traffic flow through an eswitch, a user may want to have the
ability to block traffic towards the FDB until FDB is fully programmed and
the user is ready to send traffic to it. For example: when two eswitches
are present for vports in a multi-PF setup, one eswitch may take over the
traffic from the other when the user chooses.
Before this take over, a user may want to first program the inactive
eswitch and then once ready redirect traffic to this new eswitch.
switchdev modes transition semantics:
legacy->switchdev_inactive: Create switchdev mode normally, traffic not
allowed to flow yet.
switchdev_inactive->switchdev: Enable traffic to flow.
switchdev->switchdev_inactive: Block traffic on the FDB, FDB and
representros state and content is preserved.
When eswitch is configured to this mode, traffic is ignored/dropped on
this eswitch FDB, while current configuration is kept, e.g FDB rules and
netdev representros are kept available, FDB programming is allowed.
Example:
# start inactive switchdev
devlink dev eswitch set pci/0000:08:00.1 mode switchdev_inactive
# setup TC rules, representors etc ..
# activate
devlink dev eswitch set pci/0000:08:00.1 mode switchdev

Add support for a new DSA tagging protocol driver for the MaxLinear
GSW1xx switch family. The GSW1xx switches use a proprietary 8-byte
special tag inserted between the source MAC address and the EtherType
field to indicate the source and destination ports for frames
traversing the CPU port.
Implement the tag handling logic to insert the special tag on transmit
and parse it on receive.

The layout of bits within the individual tiles
(referred to as sectors in the
DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D() macro)
changed for 8 and 16-bit surfaces starting in
Blackwell 2 GPUs (With the exception of GB10).
To denote the difference, extend the sector field
in the parametric format modifier definition used
to generate modifier values for NVIDIA hardware.
Without this change, it would be impossible to
differentiate the two layouts based on modifiers,
and as a result software could attempt to share
surfaces directly between pre-GB20x and GB20x
cards, resulting in corruption when the surface
was accessed on one of the GPUs after being
populated with content by the other.
Of note: This change causes the
DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D() macro to
evaluate its "s" parameter twice, with the side
effects that entails. I surveyed all usage of the
modifier in the kernel and Mesa code, and that
does not appear to be problematic in any current
usage, but I thought it was worth calling out.

Instead of iterating over all endpoints, under RCU read lock, just to
check if one of them as the fullmesh flag, we can keep a counter of
fullmesh endpoint, similar to what is done with the other flags.
This counter is now checked, before iterating over all endpoints.
Similar to the other counters, this new one is also exposed. A userspace
app can then know when it is being used in a fullmesh mode, with
potentially (too) many subflows.

Changing alignment of header would mean it's no longer safe to cast a
2 byte aligned pointer between formats. Use two 16 bit fields to make
it 2 byte aligned as previously.
This fixes the performance regression since
commit ("virtio_net: enable gso over UDP tunnel support.") as it uses
virtio_net_hdr_v1_hash_tunnel which embeds
virtio_net_hdr_v1_hash. Pktgen in guest + XDP_DROP on TAP + vhost_net
shows the TX PPS is recovered from 2.4Mpps to 4.45Mpps.

Introduce the userspace entry point for PHY MSE diagnostics via
ethtool netlink. This exposes the core API added previously and
returns both capability information and one or more snapshots.
Userspace sends ETHTOOL_MSG_MSE_GET. The reply carries:
- ETHTOOL_A_MSE_CAPABILITIES: scale limits and timing information
- ETHTOOL_A_MSE_CHANNEL_* nests: one or more snapshots (per-channel
if available, otherwise WORST, otherwise LINK)
Link down returns -ENETDOWN.
Changes:
- YAML: add attribute sets (mse, mse-capabilities, mse-snapshot)
and the mse-get operation
- UAPI (generated): add ETHTOOL_A_MSE_* enums and message IDs,
ETHTOOL_MSG_MSE_GET/REPLY
- ethtool core: add net/ethtool/mse.c implementing the request,
register genl op, and hook into ethnl dispatch
- docs: document MSE_GET in ethtool-netlink.rst
The include/uapi/linux/ethtool_netlink_generated.h is generated
from Documentation/netlink/specs/ethtool.yaml.

Add a new state NAPI_STATE_THREADED_BUSY_POLL to the NAPI state enum to
enable and disable threaded busy polling.
When threaded busy polling is enabled for a NAPI, enable
NAPI_STATE_THREADED also.
When the threaded NAPI is scheduled, set NAPI_STATE_IN_BUSY_POLL to
signal napi_complete_done not to rearm interrupts.
Whenever NAPI_STATE_THREADED_BUSY_POLL is unset, the
NAPI_STATE_IN_BUSY_POLL will be unset, napi_complete_done unsets the
NAPI_STATE_SCHED_THREADED bit also, which in turn will make the kthread
go to sleep.
