- make it possible to set hid_mouse_ignore_list dynamically (the same way we
handle other quirks) (Aditya Garg)
- fix potential OOB in usbhid_parse() (Terry Junge)
The current HID bpf implementation assumes no output report/request will
go through it after hid_bpf_destroy_device() has been called. This leads
to a bug that unplugging certain types of HID devices causes a cleaned-
up SRCU to be accessed. The bug was previously a hidden failure until a
recent x86 percpu change [1] made it access not-present pages.
The bug will be triggered if the conditions below are met:
A) a device under the driver has some LEDs on
B) hid_ll_driver->request() is uninplemented (e.g., logitech-djreceiver)
If condition A is met, hidinput_led_worker() is always scheduled *after*
hid_bpf_destroy_device().
hid_destroy_device
` hid_bpf_destroy_device
` cleanup_srcu_struct(&hdev->bpf.srcu)
` hid_remove_device
` ...
` led_classdev_unregister
` led_trigger_set(led_cdev, NULL)
` led_set_brightness(led_cdev, LED_OFF)
` ...
` input_inject_event
` input_event_dispose
` hidinput_input_event
` schedule_work(&hid->led_work) [hidinput_led_worker]
This is fine when condition B is not met, where hidinput_led_worker()
calls hid_ll_driver->request(). This is the case for most HID drivers,
which implement it or use the generic one from usbhid. The driver itself
or an underlying driver will then abort processing the request.
Otherwise, hidinput_led_worker() tries hid_hw_output_report() and leads
to the bug.
hidinput_led_worker
` hid_hw_output_report
` dispatch_hid_bpf_output_report
` srcu_read_lock(&hdev->bpf.srcu)
` srcu_read_unlock(&hdev->bpf.srcu, idx)
The bug has existed since the introduction [2] of
dispatch_hid_bpf_output_report(). However, the same bug also exists in
dispatch_hid_bpf_raw_requests(), and I've reproduced (no visible effect
because of the lack of [1], but confirmed bpf.destroyed == 1) the bug
against the commit (i.e., the Fixes:) introducing the function. This is
because hidinput_led_worker() falls back to hid_hw_raw_request() when
hid_ll_driver->output_report() is uninplemented (e.g., logitech-
djreceiver).
hidinput_led_worker
` hid_hw_output_report: -ENOSYS
` hid_hw_raw_request
` dispatch_hid_bpf_raw_requests
` srcu_read_lock(&hdev->bpf.srcu)
` srcu_read_unlock(&hdev->bpf.srcu, idx)
Fix the issue by returning early in the two mentioned functions if
hid_bpf has been marked as destroyed. Though
dispatch_hid_bpf_device_event() handles input events, and there is no
evidence that it may be called after the destruction, the same check, as
a safety net, is also added to it to maintain the consistency among all
dispatch functions.
The impact of the bug on other architectures is unclear. Even if it acts
as a hidden failure, this is still dangerous because it corrupts
whatever is on the address calculated by SRCU. Thus, CC'ing the stable
list.

On systems that only have an SRA sensor connected to SFH the sensor
doesn't get enabled due to a bad optimization condition of breaking
the sensor walk loop.
This optimization is unnecessary in the first place because if there
is only one device then the loop only runs once. Drop the condition
and explicitly mark sensor as enabled.

During wacom_parse_and_register() the code calls wacom_devm_kfifo_alloc
to allocate a fifo. During this operation it passes kfifo_alloc a
fifo_size of 0. Kfifo attempts to round the size passed to it to the
next power of 2 via roundup_pow_of_two (queue-type data structures
do this to maintain efficiency of operations).
However during this phase a problem arises when the roundup_pow_of_two()
function utilises a shift exponent of fls_long(n-1), where n is the
fifo_size. Since n is 0 in this case and n is also an unsigned long,
doing n-1 causes unsigned integer wrap-around to occur making the
fifo_size 4294967295. So the code effectively does fls_long(4294967295)
which results in 64. Returning back to roundup_pow_of_two(), the code
utilises a shift exponent of 64. When a shift exponent of 64 is used
on a 64-bit type such as 1UL it results in a shift-out-of-bounds.
The root cause of the issue seems to stem from insufficient validation
of wacom_compute_pktlen(), since in this case the fifo_size comes
from wacom_wac->features.pktlen. During wacom_parse_and_register()
the wacom_compute_pktlen() function sets the pktlen as 0.
To fix this, we should handle cases where wacom_compute_pktlen()
results in 0.

In wacom_wac_queue_flush() the code allocates zero initialised
buffer which it uses as a storage buffer for copying data from
a fifo via kfifo_out(). The kfifo_out() function returns the
number of elements it has copied. The code checks if the number
of copied elements does not equal the size of the fifo record,
if it does not it simply skips the entry and continues to the
next iteration. However it does not release the storage buffer
leading to a memory leak.
Fix the memory leak by freeing the buffer on size mismatch.

Some USB HID mice have drivers both in HID as well as a separate USB
driver. The already existing hid_mouse_ignore_list in hid-quirks manages
this, but is not yet configurable by usbhid.quirks, unlike all others like
hid_ignore_list. Thus in some HID devices, where the vendor provides USB
drivers only for the mouse and lets keyboard handled by the generic hid
drivers, presence of such a quirk prevents the user from compiling hid core
again to add the device to the table.

We've received lots of commits at this time, as a result of various
cleanup and refactoring works as well as a few new drivers and the
generic SoundWire support. Most of changes are device-specific,
little about the core changes. Some highlights below:
Core:
* A couple of (rather minor) race fixes in ALSA sequencer code
* A regression fix in ALSA timer code that may lead to a deadlock
ASoC:
* A large series of code conversion to use modern terminology for the
clocking configuration
* Conversions of PM ops with the modern macros in all ASoC drivers
* Clarification of the control operations
* Prepartory work for more generic SoundWire SCDA controls
* Support for AMD ACP 7.x, AWINC WM88166, Everest ES8388, Intel AVS
PEAKVOL and GAIN DSP modules Mediatek MT8188 DMIC, NXP i.MX95,
nVidia Tegra interconnects, Rockchip RK3588 S/PDIF, Texas
Instruments SN012776 and TAS5770L, and Wolfson WM8904 DMICs
Others:
* Conversions of PM ops with the modern macros in the rest drivers
* USB-audio quirks and fixes for Presonus Studio, DJM-A9, CME
* HD-audio quirks and fixes ASUS, HP, Lenovo, and others
Note that the PR contains some changes from the tip tree for AMD code,
and it might give some merge conflict due to the rebase afterwards.

This patch series is focused on improving the compatibility and usability of the
hid-pidff force feedback driver. Last patch introduces a new, universal driver
for PID devices that need some special handling like report fixups, remapping the
button range, managing new pidff quirks and setting desirable fuzz/flat values.
This work has been done in the span of the past months with the help of the great
Linux simracing community, with a little input from sim flight fans from FFBeast.
No changes interfere with compliant and currently working PID devices.
"Generic" codepath was tested as well with Moza and Simxperience AccuForce v2.
I'm not married to the name. It's what we used previously, but if "universal" is
confusing (pidff is already the generic driver), we can come up with something
better like "hid-quirky-pidff" :)
With v8 and tiny finx in v9, all the outstanding issues were resolved,
additional pidff issues were fixed and hid-pidff defines moved to a dedicated
header file. This patch series could be considered done bar any comments and
requests from input maintainers.
I could save more then a dozen lines of code by changing simple if statements
to only occupy on line instead of two in there's a need for that.
From: Mario Limonciello <mario.limonciello@amd.com>
Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.
Example use cases are "wake from suspend on approach" or to "lock
when leaving".
This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.
Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.
