commit 4f57cace81438cc873a96f9f13f08298815c9b51 upstream.
Some devices, particularly the 3DConnexion Spacemouse wireless 3D
controllers, return more than just the battery capacity in the battery
report. The Spacemouse devices return an additional byte with a device
specific field. However, hidinput_query_battery_capacity() only
requests a 2 byte transfer.
When a spacemouse is connected via USB (direct wire, no wireless dongle)
and it returns a 3 byte report instead of the assumed 2 byte battery
report the larger transfer confuses and frightens the USB subsystem
which chooses to ignore the transfer. Then after 2 seconds assume the
device has stopped responding and reset it. This can be reproduced
easily by using a wired connection with a wireless spacemouse. The
Spacemouse will enter a loop of resetting every 2 seconds which can be
observed in dmesg.
This patch solves the problem by increasing the transfer request to 4
bytes instead of 2. The fix isn't particularly elegant, but it is simple
and safe to backport to stable kernels. A further patch will follow to
more elegantly handle battery reports that contain additional data.

[ Upstream commit a5d81646fa294eed57786a9310b06ca48902adf8 ]
The Maxxter KB-BT-001 Bluetooth keyboard, which looks somewhat like the
Apple Wireless Keyboard, is using the vendor and product IDs (05AC:0239)
of the Apple Wireless Keyboard (2009 ANSI version) <sigh>.
But its F1 - F10 keys are marked as sending F1 - F10, not the special
functions hid-apple.c maps them too; and since its descriptors do not
contain the HID_UP_CUSTOM | 0x0003 usage apple-hid looks for for the
Fn-key, apple_setup_input() never gets called, so F1 - F6 are mapped
to key-codes which have not been set in the keybit array causing them
to not send any events at all.
The lack of a usage code matching the Fn key in the clone is actually
useful as this allows solving this problem in a generic way.
This commits adds a fn_found flag and it adds a input_configured
callback which checks if this flag is set once all usages have been
mapped. If it is not set, then assume this is a clone and clear the
quirks bitmap so that the hid-apple code does not add any special
handling to this keyboard.
This fixes F1 - F6 not sending anything at all and F7 - F12 sending
the wrong codes on the Maxxter KB-BT-001 Bluetooth keyboard and on
similar clones.

commit ca28aff0e1dc7dce9e12a7fd9276b7118ce5e73a upstream.
The Obins Anne Pro 2 keyboard (04d9:a293) disconnects after a few
minutes of inactivity when using it wired and typing does not result
in any input events any more. This is a common firmware flaw. So add
the ALWAYS_POLL quirk for this device.
GitHub user Dietrich Moerman (dietrichm) tested the quirk and
requested my help in my project
https://github.com/sriemer/fix-linux-mouse issue 22 to provide
this patch.

commit e72455b898ac678667c5674668186b4670d87d11 upstream.
Fix for non-working buttons on knock-off USB dongles for Sony
controllers. These USB dongles are used to connect older Sony DA/DS1/DS2
controllers via USB and are common on Amazon, AliExpress, etc. Without
the patch, the square, X, and circle buttons do not function. These
dongles used to work prior to kernel 4.10 but removing the global DS3
report fixup in commit e19a267b9987 ("HID: sony: DS3 comply to Linux gamepad
spec") exposed the problem.
Many people reported the problem on the Ubuntu forums and are working
around the problem by falling back to the 4.9 hid-sony driver.
The problem stems from these dongles incorrectly reporting their button
count as 13 instead of 16. This patch fixes up the report descriptor by
changing the button report count to 16 and removing 3 padding bits.

commit 0ed08faded1da03eb3def61502b27f81aef2e615 upstream.
The syzbot fuzzer discovered a bad race between in the usbhid driver
between usbhid_stop() and usbhid_close(). In particular,
usbhid_stop() does:
usb_free_urb(usbhid->urbin);
...
usbhid->urbin = NULL; /* don't mess up next start */
and usbhid_close() does:
usb_kill_urb(usbhid->urbin);
with no mutual exclusion. If the two routines happen to run
concurrently so that usb_kill_urb() is called in between the
usb_free_urb() and the NULL assignment, it will access the
deallocated urb structure -- a use-after-free bug.
This patch adds a mutex to the usbhid private structure and uses it to
enforce mutual exclusion of the usbhid_start(), usbhid_stop(),
usbhid_open() and usbhid_close() callbacks.

commit 778fbf4179991e7652e97d7f1ca1f657ef828422 upstream.
We've recently switched from extracting the value of HID_DG_CONTACTMAX
at a fixed offset (which may not be correct for all tablets) to
injecting the report into the driver for the generic codepath to handle.
Unfortunately, this change was made for *all* tablets, even those which
aren't generic. Because `wacom_wac_report` ignores reports from non-
generic devices, the contact count never gets initialized. Ultimately
this results in the touch device itself failing to probe, and thus the
loss of touch input.
This commit adds back the fixed-offset extraction for non-generic devices.

Note: With commit 8ec321e96e05 ("HID: Fix slab-out-of-bounds read in

"controlled" at probe if there is a report too long in the HID

presumabely we cannot always rely on this being the case.

commit beae56192a2570578ae45050e73c5ff9254f63e6 upstream.
Commit 8f18eca9ebc5 ("HID: ite: Add USB id match for Acer SW5-012 keyboard
dock") added the USB id for the Acer SW5-012's keyboard dock to the
hid-ite driver to fix the rfkill driver not working.
Most keyboard docks with an ITE 8595 keyboard/touchpad controller have the
"Wireless Radio Control" bits which need the special hid-ite driver on the
second USB interface (the mouse interface) and their touchpad only supports
mouse emulation, so using generic hid-input handling for anything but
the "Wireless Radio Control" bits is fine. On these devices we simply bind
to all USB interfaces.
But unlike other ITE8595 using keyboard docks, the Acer Aspire Switch 10
(SW5-012)'s touchpad not only does mouse emulation it also supports
HID-multitouch and all the keys including the "Wireless Radio Control"
bits have been moved to the first USB interface (the keyboard intf).
So we need hid-ite to handle the first (keyboard) USB interface and have
it NOT bind to the second (mouse) USB interface so that that can be
handled by hid-multitouch.c and we get proper multi-touch support.
This commit changes the hid_device_id for the SW5-012 keyboard dock to
only match on hid devices from the HID_GROUP_GENERIC group, this way
hid-ite will not bind the the mouse/multi-touch interface which has
HID_GROUP_MULTITOUCH_WIN_8 as group.
This fixes the regression to mouse-emulation mode introduced by adding
the keyboard dock USB id.

[ Upstream commit 8f18eca9ebc57d6b150237033f6439242907e0ba ]
The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad
which is connected to an ITE 8595 USB keyboard controller chip.
This keyboard has the same quirk for its rfkill / airplane mode hotkey as
other keyboards with the ITE 8595 chip, it only sends a single release
event when pressed and released, it never sends a press event.
This commit adds this keyboards USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard.

When polling a connected /dev/hidrawX device, it is useful to get the
EPOLLOUT when writing is possible. Since writing is possible as soon as
the device is connected, always return it.
Right now EPOLLOUT is only returned when there are also input reports
are available. This works if devices start sending reports when
connected, but some HID devices might need an output report first before
sending any input reports. This change will allow using EPOLLOUT here as
well.

Always return EPOLLOUT from hidraw_poll when a device is connected.
This is safe since writes are always possible (but will always block).
hidraw does not support non-blocking writes and instead always calls
blocking backend functions on write requests. Hence, so far, a call to
poll never returned EPOLLOUT, which confuses tools like socat.

commit 18a1b06e5b91d47dc86c0a66a762646ea7c5d141 upstream.
The open method of hiddev handler fails to bring the device out of
autosuspend state as was promised in 0361a28d3f9a, as it actually has 2
blocks that try to start the transport (call hid_hw_open()) with both
being guarded by the "open" counter, so the 2nd block is never executed as
the first block increments the counter so it is never at 0 when we check
it for the second block.
Additionally hiddev_open() was leaving counter incremented on errors,
causing the device to never be reopened properly if there was ever an
error.
Let's fix all of this by factoring out code that creates client structure
and powers up the device into a separate function that is being called
from usbhid_open() with the "existancelock" being held.

commit 8ec321e96e056de84022c032ffea253431a83c3c upstream.
The syzbot fuzzer found a slab-out-of-bounds bug in the HID report
handler. The bug was caused by a report descriptor which included a
field with size 12 bits and count 4899, for a total size of 7349
bytes.
The usbhid driver uses at most a single-page 4-KB buffer for reports.
In the test there wasn't any problem about overflowing the buffer,
since only one byte was received from the device. Rather, the bug
occurred when the HID core tried to extract the data from the report
fields, which caused it to try reading data beyond the end of the
allocated buffer.
This patch fixes the problem by rejecting any report whose total
length exceeds the HID_MAX_BUFFER_SIZE limit (minus one byte to allow
for a possible report index). In theory a device could have a report
longer than that, but if there was such a thing we wouldn't handle it
correctly anyway.

transport device
[ Upstream commit 8725aa4fa7ded30211ebd28bb1c9bae806eb3841 ]
In the event that the RMI device is unreachable, the calls to rmi_set_mode() or
rmi_set_page() will fail before registering the RMI transport device. When the
device is removed, rmi_remove() will call rmi_unregister_transport_device()
which will attempt to access the rmi_dev pointer which was not set.
This patch adds a check of the RMI_STARTED bit before calling
rmi_unregister_transport_device(). The RMI_STARTED bit is only set
after rmi_register_transport_device() completes successfully.
The kernel oops was reported in this message:

commit 1cb0d2aee26335d0bccf29100c7bed00ebece851 upstream.
Upstream commit 58e75155009c ("HID: core: move Usage Page concatenation
to Main item") adds support for Usage Page item after Usage ID items
(such as keyboards manufactured by Primax).
Usage Page concatenation in Main item works well for following report
descriptor patterns:
USAGE_PAGE (Keyboard) 05 07
USAGE_MINIMUM (Keyboard LeftControl) 19 E0
USAGE_MAXIMUM (Keyboard Right GUI) 29 E7
LOGICAL_MINIMUM (0) 15 00
LOGICAL_MAXIMUM (1) 25 01
REPORT_SIZE (1) 75 01
REPORT_COUNT (8) 95 08
INPUT (Data,Var,Abs) 81 02
-------------
USAGE_MINIMUM (Keyboard LeftControl) 19 E0
USAGE_MAXIMUM (Keyboard Right GUI) 29 E7
LOGICAL_MINIMUM (0) 15 00
LOGICAL_MAXIMUM (1) 25 01
REPORT_SIZE (1) 75 01
REPORT_COUNT (8) 95 08
USAGE_PAGE (Keyboard) 05 07
INPUT (Data,Var,Abs) 81 02
But it makes the parser act wrong for the following report
descriptor pattern(such as some Gamepads):
USAGE_PAGE (Button) 05 09
USAGE (Button 1) 09 01
USAGE (Button 2) 09 02
USAGE (Button 4) 09 04
USAGE (Button 5) 09 05
USAGE (Button 7) 09 07
USAGE (Button 8) 09 08
USAGE (Button 14) 09 0E
USAGE (Button 15) 09 0F
USAGE (Button 13) 09 0D
USAGE_PAGE (Consumer Devices) 05 0C
USAGE (Back) 0a 24 02
USAGE (HomePage) 0a 23 02
LOGICAL_MINIMUM (0) 15 00
LOGICAL_MAXIMUM (1) 25 01
REPORT_SIZE (1) 75 01
REPORT_COUNT (11) 95 0B
INPUT (Data,Var,Abs) 81 02
With Usage Page concatenation in Main item, parser recognizes all the
11 Usages as consumer keys, it is not the HID device's real intention.
This patch checks whether Usage Page is really defined after Usage ID
items by comparing usage page using status.
Usage Page concatenation on currently defined Usage Page will always
do in local parsing when Usage ID items encountered.
When Main item is parsing, concatenation will do again with last
defined Usage Page if this page has not been used in the previous
usages concatenation.

commit ff479731c3859609530416a18ddb3db5db019b66 upstream.
The HID descriptors for most Wacom devices oddly declare the serial
number and other related fields as signed integers. When these numbers
are ingested by the HID subsystem, they are automatically sign-extended
into 32-bit integers. We treat the fields as unsigned elsewhere in the
kernel and userspace, however, so this sign-extension causes problems.
In particular, the sign-extended tool ID sent to userspace as ABS_MISC
does not properly match unsigned IDs used by xf86-input-wacom and libwacom.
We introduce a function 'wacom_s32tou' that can undo the automatic sign
extension performed by 'hid_snto32'. We call this function when processing
the serial number and related fields to ensure that we are dealing with
and reporting the unsigned form. We opt to use this method rather than
adding a descriptor fixup in 'wacom_hid_usage_quirk' since it should be
more robust in the face of future devices.
