94a9992f7d HID: Increase maximum report size allowed by hid_field_extract()
Commit 71f6fa90a3 ("HID: increase maximum global item tag report size
to 256") increases the max report size from 128 to 256.

We also need to update the report size in hid_field_extract() otherwise
it complains and truncates now valid report size:
[ 406.165461] hid-sensor-hub 001F:8086:22D8.0002: hid_field_extract() called with n (192) > 32! (kworker/5:1)

6b538cc213 HID: steam: fix deadlock with input devices.
When using this driver with the wireless dongle and some usermode
program that monitors every input device (acpid, for example), while
another usermode client opens and closes the low-level device
repeadedly, the system eventually deadlocks.

The reason is that steam_input_register_device() must not be called with
the mutex held, because the input subsystem has its own synchronization
that clashes with this one: it is possible that steam_input_open() is
called before input_register_device() returns, and since
steam_input_open() needs to lock the mutex, it deadlocks.

However we must hold the mutex when calling any function that sends
commands to the controller. If not, random commands end up falling fail.

b22f805bbe HID: intel-ish-hid: Optimize writing ipc message from queue
Currently we are using one additional static variable and a spinlock to
prevent contention of writing IPC messages to ISH hardware, which is
not necessary. Once ISH is ready to accept new data, we can push new
data to hardware. This pushing of new data is already protected by
wr_processing_spinlock for contention, which is enough. So use this
spinlock to check both readiness for accepting new data and once ready
allow writing of ipc message from queue to ISH hardware.

While here, cleaned up some space after return.

0d28f49412 HID: intel-ish-hid: avoid binding wrong ishtp_cl_device
When performing a warm reset in ishtp bus driver, the ishtp_cl_device
will not be removed, its fw_client still points to the already freed
ishtp_device.fw_clients array.

Later after driver finishing ishtp client enumeration, this dangling
pointer may cause driver to bind the wrong ishtp_cl_device to the new
client, causing wrong callback to be called for messages intended for
the new client.

This helps in development of firmware where frequent switching of
firmwares is required without Linux reboot.

There is a new firmware for the Steam Controller with support for BLE

reboots itself every 10 seconds unless an application has opened it.

Doing hid_hw_open() unconditionally on probe fixes the issue, and the

aa2d495f0c HID: Add support for Toshiba WT10A tablet bluetooth keyboard
The bluetooth-keyboard which comes with the Toshiba WT10A tablet uses
a couple of usage codes in the vendor specific ffbc page.

The keyboard has a vendor-id of 04f2 which maps to Chicony.

Other then adding a few keymappings for the ffbc usages, no special
handling is necessary. So rather then adding a new hid-toshiba driver,
this commit adds the ID and 2 extra key-mappings to the hid-topseed
driver. The hid-topseed driver already contains mapping for some
ffbc usages (and does nothing else) and it already binds to another
Chicony manufactured keyboard.

Ring buffer implementation in hid_debug_event() and hid_debug_events_read()
is strange allowing lost or corrupted data. After commit 717adfdaf1
("HID: debug: check length before copy_to_user()") it is possible to enter
an infinite loop in hid_debug_events_read() by providing 0 as count, this
locks up a system. Fix this by rewriting the ring buffer implementation
with kfifo and simplify the code.

This fixes CVE-2019-3819.

2edefc056e HID: intel-ish: ipc: handle PIMR before ish_wakeup also clear PISR busy_clear bit
Host driver should handle interrupt mask register earlier than wake up ish FW
else there will be conditions when FW interrupt comes, host PIMR register still
not set ready, so move the interrupt mask setting before ish_wakeup.

Clear PISR busy_clear bit in ish_irq_handler. If not clear, there will be
conditions host driver received a busy_clear interrupt (before the busy_clear
mask bit is ready), it will return IRQ_NONE after check_generated_interrupt,
the interrupt will never be cleared, causing the DEVICE not sending following
IRQ.

Since PISR clear should not be called for the CHV device we do this change.
After the change, both ISH2HOST interrupt and busy_clear interrupt will be
considered as interrupt from ISH, busy_clear interrupt will return IRQ_HANDLED
from IPC_IS_BUSY check.

Though the message flood is annoying, the device it self works without
any issue. I suspect that the device in question takes too much time to
pull the IRQ back to high after I2C host has done reading its data.

Since the host receives all useful data, let's ignore the input report

4435ff2f09 HID: logitech: Enable high-resolution scrolling on Logitech mice
There are three features used by various Logitech mice for
high-resolution scrolling: the scrolling acceleration bit in HID++ 1.0,
and the x2120 and x2121 features in HID++ 2.0 and above. This patch
supports all three, and uses the multiplier reported by the mouse for
the HID++ 2.0+ features.

The full list of product IDs of mice which support high-resolution
scrolling was provided by Logitech, but the patch was tested using the
following mice (using the Unifying receiver):

* HID++ 1.0: Anywhere MX, Performance MX
* x2120: M560
* x2121: MX Anywhere 2, MX Master 2S

This patch is a combinations of the now-reverted commits 1ff2e1a44e,
d56ca9855b, 5fe2ccbef9, 044ee89028 together with some extra bits for the
directional and timeout-based reset.
The previous patch series was in hid-input, it appears this remainder
handling is logitech-specific and was moved to hid-logitech-hidpp.c and
renamed accordingly.

2dc702c991 HID: input: use the Resolution Multiplier for high-resolution scrolling
Windows uses a magic number of 120 for a wheel click. High-resolution
scroll wheels are supposed to use a fraction of 120 to signal smaller
scroll steps. This is implemented by the Resolution Multiplier in the
device itself.

If the multiplier is present in the report descriptor, set it to the
logical max and then use the resolution multiplier to calculate the
high-resolution events. This is the recommendation by Microsoft, see
http://msdn.microsoft.com/en-us/windows/hardware/gg487477.aspx

Note that all mice encountered so far have a logical min/max of 0/1, so
it's a binary "yes or no" to high-res scrolling anyway.

To make userspace simpler, always enable the REL_WHEEL_HI_RES bit. Where
the device doesn't support high-resolution scrolling, the value for the
high-res data will simply be a multiple of 120 every time. For userspace,
if REL_WHEEL_HI_RES is available that is the one to be used.

Potential side-effect: a device with a Resolution Multiplier applying to
other Input items will have those items set to the logical max as well.
This cannot easily be worked around but it is doubtful such devices exist.

5a4abb36f3 HID: core: process the Resolution Multiplier
The Resolution Multiplier is a feature report that modifies the value of
Usages within the same Logical Collection. If the multiplier is set to
anything but 1, the hardware reports (value * multiplier) for the same amount
of physical movement, i.e. the value we receive in the kernel is
pre-multiplied.

The hardware may either send a single (value * multiplier), or by sending
multiplier as many reports with the same value, or a combination of these two
options. For example, when the Microsoft Sculpt Ergonomic mouse Resolution
Multiplier is set to 12, the Wheel sends out 12 for every detent but AC Pan
sends out a value of 3 at 4 times the frequency.

The effective multiplier is based on the physical min/max of the multiplier
field, a logical min/max of [0,1] with a physical min/max of [1,8] means the
multiplier is either 1 or 8.

The Resolution Multiplier was introduced for high-resolution scrolling in
Windows Vista and is commonly used on Microsoft mice.

The recommendation for the Resolution Multiplier is to default to 1 for
backwards compatibility. This patch adds an arbitrary upper limit at 255. The
only known use case for the Resolution Multiplier is for scroll wheels where the
multiplier has to be a fraction of 120 to work with Windows.

The 258a:6a88 keyboard-dock shipped with the Prowise PT301 tablet is
likely another ITE based design. The controller die is directly bonded
to the PCB with a blob of black glue on top so there are no markings and
the 258a vendor-id used is unknown anywhere. But the keyboard has the
exact same hotkeys mapped to Fn+F1 - F10 as the other ITE8595 keyboard
I have *and* it has the same quirky behavior wrt the rfkill hotkey.

Either way as said this keyboard has the same quirk for its rfkill /
airplane mode hotkey as the ITE 8595 chip, it only sends a single release
event when pressed and released, it never sends a press event.

This commit adds the 258a:6a88 USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard.

The device in question stops working after receives SLEEP, ON, SLEEP
commands in a short period. The scenario is like this:
- Once the desktop session closes, it also closed the hid device, so the
device gets runtime suspended and receives a SLEEP command.
- Before calling shutdown callback, it gets runtime resumed and received
an ON command.
- In the shutdown callback, it receives another SLEEP command.

I failed to find a reliable interval between ON/SLEEP commands that can
make it work, so let's simply disable runtime PM for the device.

385a488677 HID: steam: remove input device when a hid client is running.
Previously, when a HID client such as the Steam Client was running, this
driver disabled its input device to avoid doubling the input events.

While it worked mostly fine, some games got confused by the idle gamepad,
and switched to two player mode, or asked the user to choose which gamepad
to use. Other games just crashed, probably a bug in Unity [1].

With this commit, when a HID client starts, the input device is removed;
when the HID client ends the input device is recreated.

4d26d1d1e8 Revert "HID: uhid: use strlcpy() instead of strncpy()"
This reverts commit 336fd4f5f2.

Please note that `strlcpy()` does *NOT* do what you think it does.
strlcpy() *ALWAYS* reads the full input string, regardless of the
'length' parameter. That is, if the input is not zero-terminated,
strlcpy() will *READ* beyond input boundaries. It does this, because it
always returns the size it *would* copy if the target was big enough,
not the truncated size it actually copied.

The original code was perfectly fine. The hid device is
zero-initialized and the strncpy() functions copied up to n-1
characters. The result is always zero-terminated this way.

This is the third time someone tried to replace strncpy with strlcpy in
this function, and gets it wrong. I now added a comment that should at
least make people reconsider.

sys_sendfile(), this can read from kernel memory.  Alternatively,
information can be leaked from a setuid binary that is tricked to write
to the file descriptor.  Therefore, forbid UHID_CREATE in these cases.

No other commands in uhid_char_write() are affected by this bug and
UHID_CREATE is marked as "obsolete", so apply the restriction to
UHID_CREATE only rather than to uhid_char_write() entirely.

Thanks to Dmitry Vyukov for adding uhid definitions to syzkaller and to
Jann Horn for commit 9da3f2b740 ("x86/fault: BUG() when uaccess
helpers fault on kernel addresses"), allowing this bug to be found.

0145b50566 iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers
Before this commit sensor_hub_input_attr_get_raw_value() failed to take
the signedness of 16 and 8 bit values into account, returning e.g.
65436 instead of -100 for the z-axis reading of an accelerometer.

This commit adds a new is_signed parameter to the function and makes all
callers pass the appropriate value for this.

While at it, this commit also fixes up some neighboring lines where
statements were needlessly split over 2 lines to improve readability.

10f91c73cc Input: hyper-v - fix wakeup from suspend-to-idle
It makes little sense but still possible to put Hyper-V guests into
suspend-to-idle state. To wake them up two wakeup sources were registered
in the past: hyperv-keyboard and hid-hyperv. However, since
commit eed4d47efe ("ACPI / sleep: Ignore spurious SCI wakeups from
suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch
to pm_wakeup_hard_event() API as these devices are actually the only
possible way to wakeup Hyper-V guests.

3b692c55e5 HID: asus: only support backlight when it's not driven by WMI
The Asus GL502VSK has the same 0B05:1837 keyboard as we've seen in
several Republic of Gamers laptops.

However, in this model, the keybard backlight control exposed by hid-asus
has no effect on the keyboard backlight. Instead, the keyboard
backlight is correctly driven by asus-wmi.

With two keyboard backlight devices available (and only the acer-wmi
one working), GNOME is picking the wrong one to drive in the UI.

Avoid this problem by not creating the backlight interface when we
detect a WMI-driven keyboard backlight.

We have also tested Asus GL702VMK which does have the hid-asus
backlight present, and it still works fine with this patch (WMI method
call returns UNSUPPORTED_METHOD).

A direct "depends on ASUS_WMI" is intentionally avoided so that HID_ASUS
users who have ASUS_WMI=n will not quietly lose their HID_ASUS driver on
a kernel upgrade.

044ee89028 HID: input: simplify/fix high-res scroll event handling
Commit 1ff2e1a44e ("HID: input: Create a utility class for counting
scroll events") created the helper function

    hid_scroll_counter_handle_scroll()

to handle high-res scroll events and also expose them as regular wheel
events.

But the resulting algorithm was unstable, and causes scrolling to be
very unreliable.  When you hit the half-way mark of the highres
multiplier, small highres movements will incorrectly translate into big
traditional wheel movements, causing odd jitters.

Simplify the code and make the output stable.

NOTE! I'm pretty sure this will need further tweaking.  But this at
least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into
a usable one.

69d5b97c59 HID: we do not randomly make new drivers 'default y'
.. even when that "default y" is hidden syntactically as a

	default !EXPERT

it's wrong.

The only reason something should be 'default y' is if it used to be
built-in, and it was made configurable, and the 'default y' is just
retaining the status quo.

Altheratively, the hardware for the driver has become _so_ common that
it really makes sense for everybody to build it.  Finally, one possible
reason for 'default y' is because the option is not enabling any new
code at all, but is just enabling other options (the networking people
do this for vendor options, for example, so that you can disable whole
vendors at a time).

Clearly, none of these cases hold for the BigBen Interactive Kids'
gamepad, and HID_BIGBEN_FF should thus most definitely not default
to on for everybody.

b59dfdaef1 i2c-hid: properly terminate i2c_hid_dmi_desc_override_table[] array
Commit 9ee3e06610 ("HID: i2c-hid: override HID descriptors for certain
devices") added a new dmi_system_id quirk table to override certain HID
report descriptors for some systems that lack them.

But the table wasn't properly terminated, causing the dmi matching to
walk off into la-la-land, and starting to treat random data as dmi
descriptor pointers, causing boot-time oopses if you were at all
unlucky.

Terminate the array.

We really should have some way to just statically check that arrays that
should be terminated by an empty entry actually are so.  But the HID
people really should have caught this themselves, rather than have me
deal with an oops during the merge window.  Tssk, tssk.

This reverts commit 67ddbb3e65.

67ddbb3e65 ("HID: add NOGET quirk for Eaton Ellipse MAX UPS") was reported
by Laurent Bigonville. It turns out that a later model Laurent got
doesn't need the quirk after all.

My take is that Eaton upgraded their firmwares, so we don't need it
anymore.

The old model was from 2012, so better make sure the new line works
properly by removing the quirk. This allows upower to actually fetch
the current data.

00b790ea54 HID: i2c-hid: Add a small delay after sleep command for Raydium touchpanel
Raydium touchpanel (2386:4B33) sometimes does not work in desktop session
although it works in display manager.

During user logging, the display manager exits, close the HID device,
then the device gets runtime suspended and powered off. The desktop
session begins shortly after, opens the HID device, then the device gets
runtime resumed and powered on.

If the trasition from display manager to desktop sesesion is fast, the
touchpanel cannot switch from powered off to powered on in short
timeframe. So add a small delay to workaround the issue.

array. The same thing happens to the cmd == HIDIOC{G,S}USAGES cases, where
uref->usage_index is checked against an array maximum value and then it is
used as an index in an array.

This is a summary of the HIDIOCGCOLLECTIONINDEX case, which matches the
traditional Spectre V1 first load:

	copy_from_user(uref, user_arg, sizeof(*uref))
	if (uref->usage_index >= field->maxusage)
		goto inval;
	i = field->usage[uref->usage_index].collection_index;
	return i;

This patch fixes this by sanitizing field uref->usage_index before using it
to index field->usage (HIDIOCGCOLLECTIONINDEX) or field->value in
HIDIOC{G,S}USAGES arrays, thus, avoiding speculation in the first load.

Use quirk HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE suggested by the commit

11db8173db HID: wacom: Work around HID descriptor bug in DTK-2451 and DTH-2452
The DTK-2451 and DTH-2452 have a buggy HID descriptor which incorrectly
contains a Cintiq-like report, complete with pen tilt, rotation, twist, serial
number, etc. The hardware doesn't actually support this data but our driver
duitifully sets up the device as though it does. To ensure userspace has a
correct view of devices without updated firmware, we clean up this incorrect
data in wacom_setup_device_quirks.

We're also careful to clear the WACOM_QUIRK_TOOLSERIAL flag since its presence
causes the driver to wait for serial number information (via
wacom_wac_pen_serial_enforce) that never comes, resulting in
the pen being non-responsive.

A particular touchpad (SIPODEV SP1064) refuses to supply the HID
descriptors. This patch provides the framework for overriding these
descriptors based on DMI data. It also includes the descriptors for
said touchpad, which were extracted by listening to the traffic of the
windows filter driver, as well as the DMI data for the laptops known
to use this device.
