Henrik Rydberg d682bd7f38 Revert "HID: multitouch: decide if hid-multitouch needs to handle mt devices"
This reverts commit 0db3bfc72a (""HID: multitouch: decide if hid-multitouch
needs to handle mt devices").

The generic detection of hid-mt devices has two major flaws, and was
merged prematurely. Firstly, the hid-multitouch gets loaded even when
the device is handled by a special device. Secondly, the patch only
partially duplicates the device whitelist already present in hid-core,
effectively rendering a number of devices non-functional.

Julia Lawall 8052ee5f5f HID: drivers/hid/hid-roccat.c: eliminate a null pointer dereference
It is not possible to take the lock in device if device is NULL.
The mutex_lock is thus moved after the NULL test.  New error handling
labels are added at the end to differentiate between the cases where
different sets of locks should be unlocks, and between whether or not
reader should be freed (only on error).

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
expression E, E1;
identifier f;
statement S1,S2,S3;

  ... when != if (E == NULL || ...) S1 else S2
      when != E = E1

Daniel van Vugt bca621421c HID: hid-magicmouse: Magic Trackpad has 1 button, not 2
hid-magicmouse was advertising the Apple Magic Trackpad as having 2
buttons (left and right) when it actually only has 1 button.

Advertising multiple buttons makes Xorg disable all button 2 and 3
emulation (using multi-finger clicks). So Xorg users don't get working
right/middle-click emulation out of the box.

This patch makes hid-magicmouse correctly only report one real button
for Magic Trackpad, which in turn makes Xorg enable multi-finger click
support to emulate right/middle buttons.

Terry Lambert f6a04605f3 HID: support primax keyboards violating USB HID spec
Primax keyboards with the issue this driver addresses report modifier
keys as in band key events instead of as out of band modifier bits,
resulting in the modifier keys generating key up events immediately
before the keys they are intended to modify.  This driver rewrites
the raw report data from such keyboards into USB HID 1.11 compliant
report data.  It only matches the USB vendor and product IDs for the
keyboard it has been tested on. Since there are several keyboards,
notably a number of laptops and folding USB keyboards known to have
similar unresolved problem reports, the list is expected to grow.

Now that hid-generic ignores all win7 compatible multitouch devices, this patch
allows hid-multitouch to catch them.  The idea is to rely on the quirk
HID_QUIRK_MULTITOUCH to drop the device if no ContactID is given.

There is the need for a blacklist here as other devices may need a special

James Hogan 65b01bd561 HID: hidraw: protect hidraw_disconnect() better
The function hidraw_disconnect() only acquires the hidraw minors_lock
when clearing the entry in hidraw_table. However the device_destroy()
call can cause a userland read/write to return with an error. It may
cause the program to release the file descripter before the disconnect
is finished. hidraw_disconnect() has already set hidraw->exist to 0,
which makes hidraw_release() kfree the hidraw structure, which
hidraw_disconnect() continues to access and even tries to kfree again.
Similarly if a hidraw_release() occurs after setting hidraw->exist to 0,
the same thing can happen.

This is fixed by expanding the mutex critical section to cover the whole
function from setting hidraw->exist to 0 to freeing the hidraw
structure, preventing a hidraw_release() from interfering.

receiver are exposed to user processes in separated /input/dev

Multiplayer games on single PC (like home theater PC) can

same receiver.

Up to now, when Logitech Unifying receivers are connected to a
Linux based system, a single keyboard and a single mouse are
presented to the HID Layer, even if the Unifying receiver can
pair up to six compatible devices. The Unifying receiver by default
multiplexes all incoming events (from multiple keyboards/mice)

The wdata->psy.dev pointer may point to invalid memory after a failed

This changes the wacom_probe function to fail if it cannot register the
power_supply devices. If we would want to keep the previous behaviour we had to
keep some flag about the power_supply state and check it on wacom_remove, but
this seems inappropriate here. Hence, we simply fail, too, if

David Herrmann 29d28064e2 HID: wiimote: Helper functions for synchronous requests
To initialize wiimote peripherals, the stream to the wiimote must be held
exclusively by the initializer, otherwise the initialization will fail. Many
initializations require multiple memory requests to be sent synchronously so we
need a way to lock the stream and release it when we are done.

This adds several helper functions which allow to lock the stream, then send
requests, wait for the answers and release the stream again.

When holding the lock, the function may sleep and interrupted by signals.
Also it returns after a short timeout so userspace shouldn't notice long
delays.

Jiri Kosina 35d851df23 HID: magicmouse: ignore 'ivalid report id' while switching modes, v2
This is basically a more generic respin of 23746a6 ("HID: magicmouse: ignore
'ivalid report id' while switching modes") which got reverted later by
c3a492.

It turns out that on some configurations, this is actually still the case
and we are not able to detect in runtime.

The device reponds with 'invalid report id' when feature report switching it
into multitouch mode is sent to it.

This has been silently ignored before 0825411ade ("HID: bt: Wait for ACK
on Sent Reports"), but since this commit, it propagates -EIO from the _raw
callback .

So let the driver ignore -EIO as response to 0xd7,0x01 report, as that's
how the device reacts in normal mode.

Sad, but following reality.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=35022

David Herrmann 4ea5454203 HID: Fix race condition between driver core and ll-driver
HID low level drivers register new devices with the HID core which then
adds the devices to the HID bus. The HID bus normally immediately probes
an appropriate driver which then handles HID input for this device.
The ll driver now uses the hid_input_report() function to report input
events for a specific device. However, if the HID bus unloads the driver
at the same time (for instance via a call to
 /sys/bus/hid/devices/<dev>/unbind) then the hdev->driver pointer may be
used by hid_input_report() and hid_device_remove() at the same time
which may cause hdev->driver to point to invalid memory.

This fix adds a semaphore to every hid device which protects
hdev->driver from asynchronous access. This semaphore is locked during
driver *_probe and *_remove and also inside hid_input_report(). The
*_probe and *_remove functions may sleep so the semaphore is good here,
however, hid_input_report() is in atomic context and hence only uses
down_trylock(). If it cannot acquire the lock it simply drops the input
package.

The low-level drivers report input events synchronously so
hid_input_report() should never be entered twice at the same time on the
same device. Hence, the lock should always be available. But if the
driver is currently probed/removed then the lock is not available and
dropping the package should be safe because this is what would have
happened if the package arrived some milliseconds earlier/later.

This also fixes another race condition while probing drivers:
First the *_probe function of the driver is called and only if that
succeeds, the related input device of hidinput is registered. If the low
level driver reports input events after the *_probe function returned
but before the input device is registered, then a NULL pointer
dereference will occur. (Equivalently on driver remove function).
This is not possible anymore, since the semaphore lock drops all
incoming packages until the driver/device is fully initialized.

Michal Malý 7362cd2286 HID: lg4ff - Move handling of Logitech wheels to lg4ff driver
This is the first out of five patches me and Simon Wood (CC'd) have been
working on. It separates the handling of Logite from the generic lgff driver
and adds additional features specific for the Logitech wheels, namely

- Native mode support for Driving Force GT, Driving Force Pro, G25 and G27
wheels Every Logitech wheel reports itself as generic Logitech Driving Force
wheel (VID 046d, PID c294). This is done to ensu wheel will work on every USB
HID-aware system even when no Logitech driver is available. It however limits
the capabilit wheel - range is limited to 200 degrees, G25/G27 don't report the
clutch pedal and there is only one combined axis for t brake. The switch to
native mode is done via hardware-specific command which is different for each
wheel. When the wheel receives such command, it simulates reconnect and reports
to the OS with its actual PID.

- Adjustable wheel range DFGT, DFP, G25 and G27 have variable range of the
steering wheel. The range is limited by applying a maximum constant when the
wheel is turned beyond the allowed range. The limit as also set by a
hardware-specific command. There is a comm command for DFGT, G25 and G27 and
another one for DFP. It is probably possible to use the DFP command to limit
the range other Logitech wheels too, but this is not supported by the official
Logitech driver for Windows.  The patch adds a sysfs interface which allows for
the range to be set from userspace.

- Fixed autocentering command All Logitech wheels support FF_AUTOCENTER effect.
The original implementation in the lgff driver didn't work well with patch
fixes it. According to USB communication sniffs the Formula Force EX (pretty
much rebranded original Driving Force accept the generic autocentering command,
this issue is also addressed by the patch

There are still some features this patch doesn't cover, but since some of them
will most likely require modifications of memless driver we have decided not to
include them yet.

As first we decided to move the handling of Logitech wheels from hid-lgff
driver to hid-lg4ff driver (originally used fo At also adds PID of Logitech
Driving Force GT.

David Herrmann 23c063cb02 HID: wiimote: Add output queue for wiimote driver
The raw hid output function that is supported by bluetooth low-level
hid driver does not provide an output queue and also may sleep. The
wiimote driver, though, may need to send data in atomic context so
this patch adds a buffered output queue for the wiimote driver.

We use the shared workqueue to send our buffer to the hid device.
There is always only one active worker which flushes the whole output
queue to the device. If our queue is full, every further
output is discarded.

Special care is needed in the deinitialization routine. When
wiimote_hid_remove is called, HID input is already disabled, but HID
output may still be used from our worker and is then discarded by the
lower HID layers. Therefore, we can safely disable the input layer since it
is the only layer that still sends input events.
Future sysfs attributes must be freed before unregistering input to
avoid the sysfs handlers to send input events to a non-existing input
layer.

Benjamin Tissoires b84bd27fe7 HID: hid-multitouch: fix broken eGalax
Since the inclusion of eGalax devices in 2.6.39, I've got some
bug reports for 480d and other devices.
The problem lies in the reports descriptors: eGalax supports both
pen and fingers, and so the reports descriptors contained both.
But hid-multitouch relies on them to detect the last item in each
field to send the multitouch events. In 480d, the last item is not
Y as it should but Pressure. That means that the fields are not
aligned and X,Y are at 0,0 (the other touch coordinates of the report).

With this patch, the detection is made only when the field ContactID
has been detected inside the collection.

There is still a problem with the detections of the range as stylus
and fingers may not have the same min/max, but it's a start.

Speedlink VAD Cezanne have a hardware bug that makes the cursor "jump" from one

256 can in fact never occur due to real motion, therefore those events can
safely be ignored.  The driver also drops useless EV_REL events with a value of

Michael Bauer dc0a4f0ce2 HID: Fix Logitech Driving Force Pro wheel
- Add the quirk "NOGET" to make the wheel work at all in native mode.
- Replace the somehow broken report descriptor with a custom one to have
  separate throttle and brake axes.

As there are significant differences in the descriptor (original descriptor
"hides" the separate axes in a  24 bit FF00 usagepage, new descripter replaces
that with two individual 8 bit desktop.y and desktop.rz usages) I provided a
complete replacement descriptor instead trying to patch the original one.
Patching the descriptor seems not feasible as the new one is much larger.

Note: To actually test this you have to use the tool "ltwheelconf" to put the
DFP into it's native mode - See below for more info.

Background:
Most Logitech wheels are initially reporting themselves with a "fallback"
deviceID (USB_DEVICE_ID_LOGITECH_WHEEL - 0xc294), in order to make sure they
are working even without having the proper driver installed.

If the Logitech driver is installed it sends a special command to the wheel
which sets the wheel to "native mode", enabling enhance features like:
- Clutch pedal
- extended wheel rotation range (up to 900 degrees)
- H-gate shifter
- separate axis for throttle / brake
- all buttons

When the wheel is set to native mode it basically disconnects and reconnects
with a different deviceID (USB_DEVICE_ID_LOGITECH_DFP_WHEEL - 0xc298 in this
case).

I am working on a userspace tool [1] which does the switching from fallback to
native mode. During development I found out that the Driving Force Pro wheel
is not supported in native mode - quierk NOGET is missing and the throttle and
brake axes are reported in a combined way only.

Jiri Kosina 23746a66d7 HID: magicmouse: ignore 'ivalid report id' while switching modes
The device reponds with 'invalid report id' when feature report switching it
into multitouch mode is sent to it.

This has been silently ignored before 0825411ade ("HID: bt: Wait for ACK
on Sent Reports"), but since this commit, it propagates -EIO from the _raw
callback .

So let the driver ignore -EIO as response to 0xd7,0x01 report, as that's
how the device reacts in normal mode.

Sad, but following reality.

Jarod Wilson 437f3b199c HID: assorted usage updates from hut 1.12
I've got a Tivo Slide bluetooth remote/dongle, which uses a fair number
of hid usages that aren't currently mapped in hid-input.c. I'd initially
written additions to hid-input.c with just this device in mind,
including some bits that were specific to the device. This go around,
I'm looking at adding/correcting as many generic HID usages from the HID
Usage Tables, version 1.12, as I can -- which also serves to enable all
but four of the buttons on the Tivo Slide remote[*].

Outside of fixing the obviously incorrect mapping of 0xc 0x45 from
KEY_RADIO to KEY_RIGHT, and making use of the new KEY_IMAGES (just added
in 2.6.39-rc4) for AL Image Browser instead of KEY_MEDIA, these are
purely additions, and thus should have no negative impact on any already
functional HID devices. Most of the added mappings seemed to be
perfectly logical to me, but there were a few that were mapped on more
of an "I think this makes the most sense" basis.

[*] I'll handle the last four tivo buttons via an hid-tivo.c follow-up.

Benjamin Tissoires 2955caed8b HID: hid-multitouch: refactor last_field_index
the current implementation requires the devices to report
HID_DG_CONTACTCOUNT to set the last_field_index value.
However, devices reporting in serial mode (DWAV and PenMount)
do not send this field.
Other devices (3M) add other fields in the reports descriptor
that are not multitouch related at the end, thus the need to
add a special case in the default case when handling events.

A first work around has been set up but with PenMount devices,
we have reached the limit.

The idea is to calculate the last_field_index by relying only on
multitouch fields the device send. This allows us to remove
the handling of non-multitouch events in hid-multitouch, and
guarantee that the function mt_emit_event is always called.

Benjamin Tissoires f786bba449 HID: hid-multitouch: migrate 3M PCT touch screens to hid-multitouch
This patch merges the hid-3m-pct driver into hid-multitouch.
To keep devices working the same way they used to with hid-3m-pct,
we need to add two signal/noise ratios for width and height.
We also need to work on width/height to send proper
ABS_MT_ORIENTATION flag.

Importing 3M into hid-multitouch also solved the bug in which
devices handling width and height in their report descriptors
did not show ABS_MT_TOUCH_MAJOR and ABS_MT_TOUCH_MINOR.

This device contains the very same bug in report descriptor as the
Ortek ones do (i.e. LogicalMinimum == 1, which is wrong for the key
array).

As we have more reports for the Ortek devices, we are keeping the driver
name for now. Apparently there is a chip producer which sells chip with
this buggy descriptor to multiple vendors. Thus if such reports start
to come at highger frequency, we'll either have to rename the driver
accordingly, or come up with more generic workaround.

This patch merges the hid-egalax driver into hid-multitouch.  There
are two types of devices support by the hid-egalax driver: resistive
and capacitive. Here, they are implicitly distinguished by the absence
of a HID_DG_CONTACTCOUNT field in the latter, so no special code path
needs to be introduced.

As a side effect, this patch fixes the broken suspend/resume behavior
in the old driver.
