pull-request: ieee802154 for net 2022-01-05
Below I have a last minute fix for the atusb driver.
Pavel fixes a KASAN uninit report for the driver. This version is the
minimal impact fix to ease backporting. A bigger rework of the driver to
avoid potential similar problems is ongoing and will come through net-next
when ready.

In the absence of this validation, if the user requests to
configure queues more than the enabled queues, it results in
sending the requested number of queues to the kernel stack
(due to the asynchronous nature of VF response), in which
case the stack might pick a queue to transmit that is not
enabled and result in Tx hang. Fix this bug by
limiting the total number of queues allocated for VF to
active queues of VF.

There was a wrong queues representation in sysfs during
driver's reinitialization in case of online cpus number is
less than combined queues. It was caused by stopped
NetworkManager, which is responsible for calling vsi_open
function during driver's initialization.
In specific situation (ex. 12 cpus online) there were 16 queues
in /sys/class/net/<iface>/queues. In case of modifying queues with
value higher, than number of online cpus, then it caused write
errors and other errors.
Add updating of sysfs's queues representation during driver
initialization.

When loading the i40e driver, it prints a message like: 'The driver for the
device detected a newer version of the NVM image v1.x than expected v1.y.
Please install the most recent version of the network driver.' This is
misleading as the driver is working as expected.

Hide i40e opcode information sent during response to VF in case when
untrusted VF tried to change MAC on the VF interface.
This is implemented by adding an additional parameter 'hide' to the
response sent to VF function that hides the display of error
information, but forwards the error code to VF.
Previously it was not possible to send response with some error code
to VF without displaying opcode information.

Fix it by validating if the number of bytes transferred is actually

Hytera makes a range of digital (DMR) radios. These radios can be
programmed to a allow a computer to control them over Ethernet over USB,
either using NCM or RNDIS.
This commit adds support for RNDIS for Hytera radios. I tested with a
Hytera PD785 and a Hytera MD785G. When these radios are programmed to
set up a Radio to PC Network using RNDIS, an USB interface will be added
with class 2 (Communications), subclass 2 (Abstract Modem Control) and
an interface protocol of 255 ("vendor specific" - lsusb even hints "MSFT
RNDIS?").
This patch is similar to the solution of this StackOverflow user, but
that only works for the Hytera MD785:
https://stackoverflow.com/a/53550858
To use the "Radio to PC Network" functionality of Hytera DMR radios, the
radios need to be programmed correctly in CPS (Hytera's Customer
Programming Software). "Forward to PC" should be checked in "Network"
(under "General Setting" in "Conventional") and the "USB Network
Communication Protocol" should be set to RNDIS.

The role of ena_calc_max_io_queue_num() is to return the number
of queues supported by the device, which means the return value
should be >=0.
The function that calls ena_calc_max_io_queue_num(), checks
the return value. If it is 0, it means the device reported
it supports 0 IO queues. This case is considered an error
and is handled by the calling function accordingly.
However the current implementation of ena_calc_max_io_queue_num()
is wrong, since when it detects the device supports 0 IO queues,
it returns -EFAULT.
In such a case the calling function doesn't detect the error,
and therefore doesn't handle it.
This commit changes ena_calc_max_io_queue_num() to return 0
in case the device reported it supports 0 queues, allowing the
calling function to properly handle the error case.

ena_com_tx_comp_req_id_get() checks the req_id of a received completion,
and if it is out of bounds returns -EINVAL. This is a sign that
something is wrong with the device and it needs to be reset.
The current code does not reset the device in this case, which leaves
the driver in an undefined state, where this completion is not properly
handled.
This commit adds a call to handle_invalid_req_id() in ena_clean_tx_irq()
and ena_clean_xdp_irq() which resets the device to fix the issue.
This commit also removes unnecessary request id checks from
validate_tx_req_id() and validate_xdp_req_id(). This check is unneeded
because it was already performed in ena_com_tx_comp_req_id_get(), which
is called right before these functions.

In fact, axis data in Spaceball movement reports are signed 16-bit

visually inspecting the data packets, and later verified by consulting:

Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.
This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.
So this patch moves dev->work initialization before registering input
device

Pull networking fixes from Jakub Kicinski:
"Including fixes from.. Santa?
No regressions on our radar at this point. The igc problem fixed here
was the last one I was tracking but it was broken in previous
releases, anyway. Mostly driver fixes and a couple of largish SMC
fixes.
Current release - regressions:
- xsk: initialise xskb free_list_node, fixup for a -rc7 fix
Current release - new code bugs:
- mlx5: handful of minor fixes:
- use first online CPU instead of hard coded CPU
- fix some error handling paths in 'mlx5e_tc_add_fdb_flow()'
- fix skb memory leak when TC classifier action offloads are disabled
- fix memory leak with rules with internal OvS port
Previous releases - regressions:
- igc: do not enable crosstimestamping for i225-V models
Previous releases - always broken:
- udp: use datalen to cap ipv6 udp max gso segments
- fix use-after-free in tw_timer_handler due to early free of stats
- smc: fix kernel panic caused by race of smc_sock
- smc: don't send CDC/LLC message if link not ready, avoid timeouts
- sctp: use call_rcu to free endpoint, avoid UAF in sock diag
- bridge: mcast: add and enforce query interval minimum
- usb: pegasus: do not drop long Ethernet frames
- mlx5e: fix ICOSQ recovery flow for XSK

In case of an error in mlx5e_set_features(), 'netdev->features' must be
updated with the correct state of the device to indicate which features
were updated successfully.
To do that we maintain a copy of 'netdev->features' and update it after
successful feature changes, so we can assign it to back to
'netdev->features' if needed.
However, since not all netdev features are handled by the driver (e.g.
GRO/TSO/etc), some features may not be updated correctly in case of an
error updating another feature.
For example, while requesting to disable TSO (feature which is not
handled by the driver) and enable HW-GRO, if an error occurs during
HW-GRO enable, 'oper_features' will be assigned with 'netdev->features'
and HW-GRO turned off. TSO will remain enabled in such case, which is a
bug.
To solve that, instead of using 'netdev->features' as the baseline of
'oper_features' and changing it on set feature success, use 'features'
instead and update it in case of errors.

Fix a memory leak with decap rule with internal port as destination
device. The driver allocates a modify hdr action but doesn't set
the flow attr modify hdr action which results in skipping releasing
the modify hdr action when releasing the flow.

[Why]
A porting error on a previous patch left the block of code that
causes the crash from a NULL pointer dereference.
More specifically, we try to access link_enc before it's assigned in
the USB4 case in the following assignment:
config.dio_output_idx = link_enc->transmitter - TRANSMITTER_UNIPHY_A;
[How]
That assignment occurs later depending on the ASIC version. It's only
needed on DCN31 and only after link_enc is already assigned.

[Why]
We'll exit optimized power state to do link detection but we won't enter
back into the optimized power state.
This could potentially block s2idle entry depending on the sequencing,
but it also means we're losing some power during the transition period.
[How]
Hook up the handler like DCN21. It was also missed like the
exit_optimized_pwr_state callback.

[Why]
Otherwise SMU won't mark Display as idle when trying to perform s2idle.
[How]
Mark the bit in the dcn31 codepath, doesn't apply to older ASIC.
It needed to be split from phy refclk off to prevent entering s2idle
when PSR was engaged but driver was not ready.

It was reported that when PCIe PTM is enabled, some lockups could

While the issue is investigated, we can disable crosstimestamp for
those models and see no loss of functionality, because those models
don't have any support for time synchronization.
