`i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data
into `ihid->rawbuf`.
The former can come from the userspace in the hidraw driver and is only
bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set
`max_buffer_size` field of `struct hid_ll_driver` which we do not).
The latter has size determined at runtime by the maximum size of
different report types you could receive on any particular device and
can be a much smaller value.
Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`.
The impact is low since access to hidraw devices requires root.

Some VTL-class touchpads (e.g. TOPS0102:00 35CC:0104) intermittently
fail to release a finger contact. A previous slot remains logically
active, accompanied by stale BTN_TOOL_DOUBLETAP state, causing
gestures to stay latched and resulting in stuck two-finger
scrolling and false right-clicks.
Apply MT_QUIRK_STICKY_FINGERS to handle the unreleased contact correctly.

Some systems have enabled ISH without any sensors. In this case sending
HOSTIF_DM_ENUM_DEVICES results in 0 sensors. This triggers ISH hardware
reset on subsequent enumeration after S3/S4 resume.
The enum_devices_done flag was not reset before sending the
HOSTIF_DM_ENUM_DEVICES command. On subsequent enumeration calls (such as
after S3/S4 resume), this flag retains its previous true value, causing the
wait loop to be skipped and returning prematurely to hid_ishtp_cl_init().
If 0 HID devices are found, hid_ishtp_cl_init() skips getting HID device
descriptors and sets init_done to true. When the delayed enumeration
response arrives with init_done already true, the driver treats it as a bad
packet and triggers an ISH hardware reset.
Set enum_devices_done to false before sending the enumeration command,
consistent with similar functions like ishtp_get_hid_descriptor() and
ishtp_get_report_descriptor() which reset their respective flags.

When a new PlayStation gamepad (DualShock 4 or DualSense) is initialized,
the input subsystem sets the default value for its absolute axes (e.g.,
ABS_X, ABS_Y) to 0.
However, the hardware's actual neutral/resting state for these joysticks
is 128 (0x80). This creates a mismatch.
When the first HID report arrives from the device, the driver sees the
resting value of 128. The kernel compares this to its initial state of 0
and incorrectly interprets this as a delta (0 -> 128). Consequently, it
generates EV_ABS events for this initial, non-existent movement.
This behavior can fail userspace 'sanity check' tests (e.g., in
Android CTS) that correctly assert no motion events should be generated
from a device that is already at rest.
This patch fixes the issue by explicitly setting the initial value of the
main joystick axes (e.g., ABS_X, ABS_Y, ABS_RX, ABS_RY) to 128 (0x80)
in the common ps_gamepad_create() function.
This aligns the kernel's initial state with the hardware's expected
neutral state, ensuring that the first report (at 128) produces no
delta and thus, no spurious event.

The scroll resolution multipliers are set in the context of
hidinput_connect(), which is only called at probe time: when the host
changes the value on the device with a SET_REPORT(FEATURE), and the device
accepts it, these multipliers are stored on the host side, and used to
calculate the final scroll event values sent to userspace.
After a USB suspend, the resume operation on many hubs and chipsets
involve a USB reset signal as well. A reset on the device side clears all
previous state information, including the value of the multiplier report.
This reset is not handled by the multiplier handling logic, so what ends up
happening is the host is still expecting high-resolution scroll events,
but the device is reset to default resolution, making the effective,
user-perceived scroll speed incredibly slow.
The solution is to renegotiate the multiplier selection after each reset.
This is not the only bug related to the high-resolution scrolling
implementation in the kernel (the other one is
https://bugzilla.kernel.org/show_bug.cgi?id=220144), but for this one,
there is no device side workaround for, leading to poor user experience with our product:
https://github.com/UltimateHackingKeyboard/firmware/issues/1155https://github.com/UltimateHackingKeyboard/firmware/issues/1261https://github.com/UltimateHackingKeyboard/firmware/pull/1355
This patch was tested by an affected user and has been reported to
fix the issue (see discussion in 1355).

The mouse portion of the device's Report Descriptor declares 5 buttons but only
declares 3 usages (Button 1 through Button 3). As a result events for the 2
side buttons are not generated.
Detect and repair the Report Descriptor if necessary by changing the Usage
Maximum value from Button 3 to Button 5.

Since commit 6f20d3261265 ("HID: logitech-dj: Fix error handling in
logi_dj_recv_switch_to_dj_mode()") logi_dj_recv_switch_to_dj_mode()
will return an error when the hid_hw_raw_request() call to enable
[dis]connect events fails.
This can happen when used with a KVM like the Aten CS1784a and the PC
does not have the KVM focus when probe() runs, which causes probe() to
fail after which the receiver will simply not work.
The logi_dj_recv_query_paired_devices() call done at the end of probe()
already ignores any errors for the KVM without focus case. When focus is
restored and an input report is received this will trigger
logi_dj_recv_queue_unknown_work() which retries the query_paired_devices()
call from a workqueue.
To fix the probe() failure let it ignore logi_dj_recv_switch_to_dj_mode()
errors too, track if a successful logi_dj_recv_switch_to_dj_mode() was
done and retry if necessary from logi_dj_recv_queue_unknown_work().
Queurying paired devices while not in dj-mode is not useful and this
will be redone after the unknown work has retried setting dj-mode,
so skip queurying paired devices when not in dj-mode yet.
The new bool to track successful setting of the dj-mode will also cause
setting dj-mode to be retried from the unknown work, if setting dj-mode
failed after a reset_resume.

logi_dj_recv_query_paired_devices() and logi_dj_recv_switch_to_dj_mode()
both have 2 callers which all log an error if the function fails. Move
the error logging to inside these 2 functions to remove the duplicated
error logging in the callers.
While at it also move the logi_dj_recv_send_report() call error handling
in logi_dj_recv_switch_to_dj_mode() to directly after the call. That call
only fails if the report cannot be found and in that case it does nothing,
so the msleep() is not necessary on failures.

The Logitech G Pro X Superlight 2 has a lightspeed receiver with a
product id of 0xc54d, this receiver behaves like the receiver used in
the original Logitech G Pro X Superlight (id 0xc547) including the 13
byte mouse reports.
This change adds a definition for this receiver id, and a mapping for
the recvr_type_gaming_hidpp_ls_1_3 type. With this change in place the
receiver now reports the battery status of the connected mouse over
wireless as well as exposing the HID interface needed for userspace to
perform additional configuration with libratbag/Piper.

HID_GD_Z is mapped to ABS_Z for stylus and pen in hid-input.c. But HID_GD_Z
should be used to report ABS_DISTANCE for stylus and pen as described at:
Documentation/input/event-codes.rst#n226
* ABS_DISTANCE:
- Used to describe the distance of a tool from an interaction surface. This
event should only be emitted while the tool is hovering, meaning in close
proximity of the device and while the value of the BTN_TOUCH code is 0. If
the input device may be used freely in three dimensions, consider ABS_Z
instead.
- BTN_TOOL_<name> should be set to 1 when the tool comes into detectable
proximity and set to 0 when the tool leaves detectable proximity.
BTN_TOOL_<name> signals the type of tool that is currently detected by the
hardware and is otherwise independent of ABS_DISTANCE and/or BTN_TOUCH.
This patch makes the correct mapping. The ABS_DISTANCE is currently not mapped
by any HID usage in hid-generic driver.

When pressing the phsyical eraser button (remapped by us to the
Secondary Barrel Switch) while the tip is down, the device
gives us several false reports with a Tip Switch 0:
press| |release
SBS: [0 0 ... 1 1 1 ... 1 0 0 0 0 0 0 ...]
TS: [1 1 ... 1 0 1 ... 1 1 0 0 0 1 1 ...]
In both press/release the number of Tip Switch 0 reports can be up to 4
and *sometimes* the Tip Switch is released in the same report
as the button press/release event.
Paper over this by forcing the tip down for a few reports if it was down
before the button toggled.

Several bugs as outlined in udev-hid-bpf#66 and udev-hid-bpf!198:
- pressure curve is far from linear
- tilt range is ±60, not ±127
- pressing the second button sets both tip down and
barrel switch
Fix the second button by adding a Secondary Barrel Switch in the
existing padding and check for the tip down/barrel switch down combo.
When both values become true at the same time, set the Secondary Barrel
Switch instead.
Implement a custom pressure curve that maps the hardware range 0-102
linearly to the logical range 0-1224, and maps the hardware range
103-2047 logarithmically to the logical range 1232-2047. This mapping
isn’t perfect, but it’s way more natural than the stock configuration.

The 3Dconnexion SpaceNavigator HID report descriptor declares its axis
data to be "relative" when it is actually "absolute". This quirk was
addressed in the kernel in 2.6.33, but some SpaceNavigator variants have
a slightly different report descriptor whose axis input items are at
different offsets than those assumed by the kernel fixup.
Add a BPF fixup to handle both sets of offsets for known SpaceNavigator
variants if the descriptor has not already been fixed by the kernel.

This assumes that the tablet has been switched into vendor mode (by
using huion-switcher[1], for example) and is sending events using
Huion's proprietary data format.
This has been tested using the PW600L pen, which does not have an
eraser. There is no expectation that a pen with an eraser will work at
this time.
