[ Upstream commit f2f10b7e722a75c6d75a7f7cd06b0eee3ae20f7c ]
Add support for media keys on the keyboard that comes with the
Asus V221ID and ZN241IC All In One computers.
The keys to support here are WLAN, BRIGHTNESSDOWN and BRIGHTNESSUP.
This device is not visibly branded as Chicony, and the USB Vendor ID
suggests that it is a JESS device. However this seems like the right place
to put it: the usage codes are identical to the currently supported
devices, and this driver already supports the ASUS AIO keyboard AK1D.

commit f043bfc98c193c284e2cd768fefabe18ac2fed9b upstream.
The hid descriptor identifies the length and type of subordinate
descriptors for a device. If the received hid descriptor is smaller than
the size of the struct hid_descriptor, it is possible to cause
out-of-bounds.
In addition, if bNumDescriptors of the hid descriptor have an incorrect
value, this can also cause out-of-bounds while approaching hdesc->desc[n].
So check the size of hid descriptor and bNumDescriptors.

[ Upstream commit a89af4abdf9b353cdd6f61afc0eaaac403304873 ]
Support for the Asus Touchpad was recently added. It turns out this
device can fail initialisation (and become unusable) when the RESET
command is sent too soon after the POWER ON command.
Unfortunately the i2c-hid specification does not specify the need for
a delay between these two commands. But it was discovered the Windows
driver has a 1ms delay.
As a result, this patch modifies the i2c-hid module to add a sleep
inbetween the POWER ON and RESET commands which lasts between 1ms and 5ms.
See https://github.com/vlasenko/hid-asus-dkms/issues/24 for further
details.

commit 2ac97f0f6654da14312d125005c77a6010e0ea38 upstream.
The following Smatch complaint was generated in response to commit
2a6cdbd ("HID: wacom: Introduce new 'touch_input' device"):
drivers/hid/wacom_wac.c:1586 wacom_tpc_irq()
error: we previously assumed 'wacom->touch_input' could be null (see line 1577)
The 'touch_input' and 'pen_input' variables point to the 'struct input_dev'
used for relaying touch and pen events to userspace, respectively. If a
device does not have a touch interface or pen interface, the associated
input variable is NULL. The 'wacom_tpc_irq()' function is responsible for
forwarding input reports to a more-specific IRQ handler function. An
unknown report could theoretically be mistaken as e.g. a touch report
on a device which does not have a touch interface. This can be prevented
by only calling the pen/touch functions are called when the pen/touch
pointers are valid.

commit 282e4637bc1c0b338708bcebd09d31c69abec070 upstream.
Commit 025bcc1 performed cleanup work on the 'wacom_pl_irq' function, making
it follow the standards used in the rest of the codebase. The change
unintiontionally allowed the function to send input events from reports
that are not marked as being in prox. This can cause problems as the
report values for X, Y, etc. are not guaranteed to be correct. In
particular, occasionally the tablet will send a report with these values
set to zero. If such a report is received it can caus an unexpected jump
in the XY position.
This patch surrounds more of the processing code with a proximity check,
preventing these zeroed reports from overwriting the current state. To
be safe, only the tool type and ABS_MISC events should be reported when
the pen is marked as being out of prox.

commit 67f8ecc550b5bda03335f845dc869b8501d25fd0 upstream.
Many devices use userspace bluetooth stacks like BlueZ or Bluedroid in combination
with uhid. If any of these stacks is used with a HID device for which the driver
performs a HID request as part .probe (or technically another HID operation),
this results in a deadlock situation. The deadlock results in a 5 second timeout
for I/O operations in HID drivers, so isn't fatal, but none of the I/O operations
have a chance of succeeding.
The root cause for the problem is that uhid only allows for one request to be
processed at a time per uhid instance and locks out other operations. This means
that if a user space is creating a new HID device through 'UHID_CREATE', which
ultimately triggers '.probe' through the HID layer. Then any HID request e.g. a
read for calibration data would trigger a HID operation on uhid again, but it
won't go out to userspace, because it is still stuck in UHID_CREATE.
In addition bluetooth stacks are typically single threaded, so they wouldn't be
able to handle any requests while waiting on uhid.
Lucikly the UHID spec is somewhat flexible and allows for fixing the issue,
without breaking user space. The idea which the patch implements as discussed
with David Herrmann is to decouple adding of a hid device (which triggers .probe)
from UHID_CREATE. The work will kick off roughly once UHID_CREATE completed (or
else will wait a tiny bit of time in .probe for a lock). A HID driver has to call
HID to call 'hid_hw_start()' as part of .probe once it is ready for I/O, which
triggers UHID_START to user space. Any HID operations should function now within
.probe and won't deadlock because userspace is stuck on UHID_CREATE.
We verified this patch on Bluedroid with Android 6.0 and on desktop Linux with
BlueZ stacks. Prior to the patch they had the deadlock issue.

commit 19f4c2ba869517048add62c202f9645b6adf5dfb upstream.
When setting the operational mode, some third party (Speedlink Strike-FX)
gamepads refuse the output report. Failing here means we refuse to
initialize the gamepad while this should be harmless.
The weird part is that the initial commit that added this: a7de9b8
("HID: sony: Enable Gasia third-party PS3 controllers") mentions this
very same controller as one requiring this output report.
Anyway, it's broken for one user at least, so let's change it.
We will report an error, but at least the controller should work.
And no, these devices present themselves as legacy Sony controllers
(VID:PID of 054C:0268, as in the official ones) so there are no ways
of discriminating them from the official ones.

commit 972e6a993f278b416a8ee3ec65475724fc36feb2 upstream.
The usbhid driver has inconsistently duplicated code in its post-reset,
resume, and reset-resume pathways.
reset-resume doesn't check HID_STARTED before trying to
restart the I/O queues.
resume fails to clear the HID_SUSPENDED flag if HID_STARTED
isn't set.
resume calls usbhid_restart_queues() with usbhid->lock held
and the others call it without holding the lock.
The first item in particular causes a problem following a reset-resume
if the driver hasn't started up its I/O. URB submission fails because
usbhid->urbin is NULL, and this triggers an unending reset-retry loop.
This patch fixes the problem by creating a new subroutine,
hid_restart_io(), to carry out all the common activities. It also
adds some checks that were missing in the original code:
After a reset, there's no need to clear any halted endpoints.
After a resume, if a reset is pending there's no need to
restart any I/O until the reset is finished.
After a resume, if the interrupt-IN endpoint is halted there's
no need to submit the input URB until the halt has been
cleared.

The tablet behaves as if it was a regular Bamboo device with pen, touch

The weird part is that the pad is still sending events and given that
there is no input node connected to it, we get anull pointer exception.

commit 5d74325a2201376a95520a4a38a1ce2c65761c49 upstream.
The patch that added Logitech Dual Action gamepad support forgot to
update the special driver list for the device. This caused the logitech
driver not to probe unless kernel module load order was favorable.
Update the special driver list to fix it. Thanks to Simon Wood for the
idea.

commit 73e7d63efb4d774883a338997943bfa59e127085 upstream.
as reported by https://bugzilla.kernel.org/show_bug.cgi?id=108481
This bug reports mentions 6d4f5440 ("HID: multitouch: Fetch feature
reports on demand for Win8 devices") as the origin of the problem but this
commit actually masked 2 firmware bugs that are annihilating each other:
The report descriptor declares two features in reports 3 and 5:
0x05, 0x0d, // Usage Page (Digitizers) 318
0x09, 0x0e, // Usage (Device Configuration) 320
0xa1, 0x01, // Collection (Application) 322
0x85, 0x03, // Report ID (3) 324
0x09, 0x22, // Usage (Finger) 326
0xa1, 0x00, // Collection (Physical) 328
0x09, 0x52, // Usage (Inputmode) 330
0x15, 0x00, // Logical Minimum (0) 332
0x25, 0x0a, // Logical Maximum (10) 334
0x75, 0x08, // Report Size (8) 336
0x95, 0x02, // Report Count (2) 338
0xb1, 0x02, // Feature (Data,Var,Abs) 340
0xc0, // End Collection 342
0x09, 0x22, // Usage (Finger) 343
0xa1, 0x00, // Collection (Physical) 345
0x85, 0x05, // Report ID (5) 347
0x09, 0x57, // Usage (Surface Switch) 349
0x09, 0x58, // Usage (Button Switch) 351
0x15, 0x00, // Logical Minimum (0) 353
0x75, 0x01, // Report Size (1) 355
0x95, 0x02, // Report Count (2) 357
0x25, 0x03, // Logical Maximum (3) 359
0xb1, 0x02, // Feature (Data,Var,Abs) 361
0x95, 0x0e, // Report Count (14) 363
0xb1, 0x03, // Feature (Cnst,Var,Abs) 365
0xc0, // End Collection 367
The report ID 3 presents 2 input mode features, while only the first one
is handled by the device. Given that we did not checked if one was
previously assigned, we were dealing with the ignored featured and we
should never have been able to switch this panel into the multitouch mode.
However, the firmware presents an other bugs which allowed 6d4f5440
to counteract the faulty report descriptor. When we request the values
of the feature 5, the firmware answers "03 03 00". The fields are correct
but the report id is wrong. Before 6d4f5440, we retrieved all the features
and injected them in the system. So when we called report 5, we injected
in the system the report 3 with the values "03 00".
Setting the second input mode to 03 in this report changed it to "03 03"
and the touchpad switched to the mt mode. We could have set anything
in the second field because the actual value (the first 03 in this report)
was given by the query of report ID 5.
To sum up: 2 bugs in the firmware were hiding that we were accessing the
wrong feature.

commit e470127e9606b1fa151c4184243e61296d1e0c0f upstream.
The critical section protected by usbhid->lock in hid_ctrl() is too
big and because of this it causes a recursive deadlock. "Too big" means
the case statement and the call to hid_input_report() do not need to be
protected by the spinlock (no URB operations are done inside them).
The deadlock happens because in certain rare cases drivers try to grab
the lock while handling the ctrl irq which grabs the lock before them
as described above. For example newer wacom tablets like 056a:033c try
to reschedule proximity reads from wacom_intuos_schedule_prox_event()
calling hid_hw_request() -> usbhid_request() -> usbhid_submit_report()
which tries to grab the usbhid lock already held by hid_ctrl().
There are two ways to get out of this deadlock:
1. Make the drivers work "around" the ctrl critical region, in the
wacom case for ex. by delaying the scheduling of the proximity read
request itself to a workqueue.
2. Shrink the critical region so the usbhid lock protects only the
instructions which modify usbhid state, calling hid_input_report()
with the spinlock unlocked, allowing the device driver to grab the
lock first, finish and then grab the lock afterwards in hid_ctrl().
This patch implements the 2nd solution.

When connecting the Cintiq Companion 2 as an external tablet (i.e., using
it in "hybrid" mode) it has been seen to cause the kernel of the machine
it is connected to to Oops. The cause has been traced to us attempting to
switch the tablet's mode prior to actually starting HID device (resulting
in the eventual dereference of the uninitialized control URB).
Commit 3b164a0 moved the mode switch from occuring post-start to occurring
pre-start. The change was not seen to cause issues largely due to the fact
that most devices mode switch with 'hid_hw_raw_request' (which is safe to
call prior to start) rather than 'hid_hw_request'.
Moving the call back to its original location resolves the issue, but
causes some touch-only Bamboo tablets (e.g. 056a:00d0) to stop working.
The affected tablets require us to perform a mode switch on their
vestigial pen interface prior ignoring with -ENODEV, meaning that the
code which is responsible for doing the ignoring has to move as well.

looks at the wrong bytes in the report when deciding whether ABS_MISC

When support for the Cintiq Companion Hybrid and Cintiq Companion 2 was
added (36d3c51 and f7acb55), the 'wacom_query_tablet_data' function was
updated to include references to CINTIQ_HYBRID and CINTIQ_COMPANION_2
with the thought that they were necessary to switch the touch interface
into the proper mode. This is unnecessary, however, since those types
are only ever associated with the pen interface -- the touch interfaces
are either CINTIQ_24HDT or HID_GENERIC. To avoid confusion in the future,
we remove the unnecessary CINTIQ_HYBRID and CINTIQ_COMPANION_2 conditions.

When introduced in commit 1b5d514, the check 'if (hid_data->cc_index >= 0)'
in 'wacom_wac_finger_pre_report' was intended to switch where the driver
got the expected number of contacts from: HID_DG_CONTACTCOUNT if the usage
was present, or 'touch_max' otherwise. Unfortunately, an oversight worthy
of a brown paper bag (specifically, that 'cc_index' could never be negative)
meant that the latter 'else' clause would never be entered.
The patch prior to this one introduced a way for 'cc_index' to be negative,
but only if HID_DG_CONTACTCOUNT is present in some report _other_ than the
one being processed. To ensure the 'else' clause is also entered for devices
which don't have HID_DG_CONTACTCOUNT on _any_ report, we add the additional
constraint that 'cc_report' be non-zero (which is true only if the usage is
present in some report).

The cached indicies 'cc_index' and 'cc_value_index' introduced in 1b5d514
are only valid for a single report ID. If a touchscreen has multiple
reports with a HID_DG_CONTACTCOUNT usage, its possible that the values
will not be correct for the report we're handling, resulting in an
incorrect value for 'num_expected'. This has been observed with the Cintiq
Companion 2.
To address this, we store the ID of the report those indicies are valid
for in a new 'cc_report' variable. Before using them to get the expected
contact count, we first check if the ID of the report we're processing
matches 'cc_report'. If it doesn't, we update the indicies to point to
the HID_DG_CONTACTCOUNT usage of the current report (if it has one).

The new Intuos tablets added in eda01da and the Cintiq 13HD Touch added
in b4bf212 are capable of reporting 2048 levels of pressure. Although the
kernel reports the correct range to userspace, an oversight has resulted
in the driver ingoring the 11th pressure bit and only sending pressures
of 0 through 1023.
We could fix this issue by expanding the type check to include these
devices, but it makes much more sense to just have the driver look at
the device's maximum pressure when determining if it should read the
11th bit.
