Nikolai Kondrashov 102750b8c9 HID: kye: Rename MousePen i608X v2 macro
Rename the device ID macro for the second version of KYE MousePen i608x
graphics tablet to have "V" in its name to signify that "2" is a
version.

I.e. USB_DEVICE_ID_KYE_MOUSEPEN_I608X_2 ->
     USB_DEVICE_ID_KYE_MOUSEPEN_I608X_V2

This also makes applying additional fixes from DIGImend easier.

This patch validates the num_values parameter from userland during the

to HID_REPORT_ID_UNKNOWN, we would fail to validate the num_values parameter

Trent Lloyd 282bf1fe6d HID: usbhid: quirks for Corsair RGB keyboard & mice (K70R, K95RGB, M65RGB, K70RGB, K65RGB)
These devices feature multiple interfaces/endpoints: a legacy BIOS/boot
interface (endpoint 0x81), as well as 2 corsair-specific keyboard interfaces
(endpoint 0x82, 0x83 IN/0x03 OUT) and an RGB LED control interface (endpoint
0x84 IN/0x04 OUT)

Because the extra 3 interfaces are not of subclass USB_INTERFACE_SUBCLASS_BOOT,
HID_QUIRK_NOGET is not automatically set on them and a 10s timeout per-endpoint
(30s per device) occurs initialising reports on boot.  We configure
HID_QUIRK_NO_INIT_REPORTS for these devices.

Additionally the left-side G1-G18 macro keys on the K95RGB generate output on
the un-opened 0x82/0x83 endpoints which causes the keyboard to stop responding
waiting for this event to be collected.  We enable HID_QUIRK_ALWAYS_POLL to
prevent this situation from occurring.

Alan Stern 972e6a993f HID: usbhid: fix inconsistent reset/resume/reset-resume behavior
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.

Daniel Bristot de Oliveira c14022bfd2 HID: usbhid: enable NO_INIT_REPORTS quirk for Semico USB Keykoard2
The device which identifies itself as a "USB Keykoard" (no typo)
with VID:PID 1a2c:0027 does not seem to be handling the reports
initialization very well.

This results in a "usb_submit_urb(ctrl) failed: -1" message from the
kernel when connected, and a delay before its initialization. It can
also cause the hang the system.

This patch adds the  quirk for this device, which causes the delay
to disappear. It is named as "USB Keykoard2" because the "USB Keykoard"
already exists.

Ioan-Adrian Ratiu e470127e96 HID: usbhid: fix recursive deadlock
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.

The "XInput" mode works fine, the controller is recognized as a xbox

In "DInput" mode the device is recognized as some kind of mouse input but no
joystick is created. This commit will change this behavior with
HID_QUIRK_MULTI_INPUT to split the device into 4 input devices so that it will
also create joysticks in /dev/input/js*.

It was reported that after 10-20 reboots, a usb keyboard plugged

Using usbmon, it turns out the interrupt URBs were streaming with
callback errors of -71 for some reason.  The hid-core.c::hid_io_error was
supposed to retry and then reset, but the reset wasn't really happening.

The check for HID_NO_BANDWIDTH was inverted.  Fix was simple.

Jim Keir e8f46e4f93 HID: pidff: support more than one concurrent effect
The PID driver (usbhid/hid-pidff.c) does not set the effect ID when
uploading an effect. The result is that the initial upload works but
subsequent uploads to modify effect parameters are all directed at the
last-created effect.

The targeted effect ID must be passed back to the device when effect
parameters are changed. This is done at the start of
"pidff_set_condition_report", "pidff_set_periodic_report" etc. based on
the value of "pidff->block_load[PID_EFFECT_
BLOCK_INDEX].value[0]".

This value is only ever set during pidff_request_effect_upload.
The result is stored in "pidff->pid_id[effect->id]" at the end of
pid_upload_effect, for later use. However, if an effect is modified and
re-sent then this identifier is not being copied back from
pidff->pid_id[effect->id] before sending the command to the device. The
fix is to do this at the start of pidff_upload_effect.

Benjamin Tissoires 70b69cfb88 HID: uclogic: Set quirks from inside the driver
Based on a patch from: Nikolai Kondrashov <Nikolai.Kondrashov@redhat.com>

Most of the tablets handled by hid-uclogic already use MULTI_INPUT.
For the ones which are not quirked in usbhid/hidquirks, they have a
custom report descriptor which contains only one report per HID
interface. For those tablets HID_QUIRK_MULTI_INPUT is transparent.

According to https://github.com/DIGImend/tablets, the only problematic
tablet currently handled by hid-uclogic is the TWHA60 v3. This tablet
presents different report descriptors from the ones currently quirked.
This is not a problem per se, given that this tablet is not supported
currently in this version (it needs the same command as a Huion to
start forwarding events).

Jim Keir afd700d933 HID: pidff: Fix initialisation forMicrosoft Sidewinder FF Pro 2
The FF2 driver (usbhid/hid-pidff.c) sends commands to the stick during ff_init.
However, this is called inside a block where driver_input_lock is locked, so
the results of these initial commands are discarded. This behavior is the
"killer", without this nothing else works.

ff_init issues commands using "hid_hw_request". This eventually goes to
hid_input_report, which returns -EBUSY because driver_input_lock is locked. The
change is to delay the ff_init call in hid-core.c until after this lock has
been released.

Calling hid_device_io_start() releases the lock so the device can be
configured.  We also need to call hid_device_io_stop() on exit for the lock to
remain locked while ending the init of the drivers.

Benjamin Tissoires b905811a49 HID: usbhid: prevent unwanted events to be sent when re-opening the device
When events occurs while no one is listening to the node (hid->open == 0
and usb_kill_urb() called) some events are still stacked somewhere in
the USB (kernel or device?) stack. When the node gets reopened, these
events are drained, and this results in spurious touch down/up, or mouse
button clicks.

The problem was spotted with touchscreens in fdo bug #81781 [1], but it
actually occurs with any mouse using hid-generic or touchscreen.

A way to reproduce it is to call:

$ xinput disable 9 ; sleep 5 ; xinput enable 9

With 9 being the device ID for the touchscreen/mouse. During the "sleep",
produce some touch events or click events. When "xinput enable" is called,
at least one click is generated.

This patch tries to fix this by draining the queue for 50 msec and
during this time frame, not forwarding these old events to the hid layer.

Hans completed the explanation:
"""
Devices like mice (basically any hid device) will have a fifo
on the device side, when we stop submitting urbs to get hid reports from
it, that fifo will fill up, and when we resume we will get whatever
is there in that fifo.

Enable the always-poll quirk for Elan Touchscreens found on some recent
Samsung laptops.

Without this quirk the device keeps disconnecting from the bus (and is
re-enumerated) unless opened (and kept open, should an input event
occur).

Note that while the device can be run-time suspended, the autosuspend
timeout must be high enough to allow the device to be polled at least
once before being suspended. Specifically, using autosuspend_delay_ms=0
will still cause the device to disconnect on input events.

Alan Stern 8f507ef522 HID: usbhid: improve handling of Clear-Halt and reset
This patch changes the way usbhid carries out Clear-Halt and reset.

Currently, after a Clear-Halt on the interrupt-IN endpoint, the driver
immediately restarts the interrupt URB, even if the Clear-Halt failed.
This doesn't work out well when the reason for the failure was that
the device was disconnected (when a low- or full-speed device is
connected through a hub to an EHCI controller, transfer errors caused
by disconnection are reported as stalls by the hub).  Instead now the
driver will attempt a reset after a failed Clear-Halt.

The way resets are carried out is also changed.  Now the driver will
call usb_queue_reset_device() instead of calling usb_reset_device()
directly.  This avoids a deadlock that would arise when a device is
unplugged: The hid_reset() routine runs as a workqueue item, a reset
attempt after the device has been unplugged will fail, failure will
cause usbhid to be unbound, and the disconnect routine will try to do
cancel_work_sync().  The usb_queue_reset_device() implementation is
carefully written to handle scenarios like this one properly.

Benjamin Tissoires e534a93522 HID: sony: do not rely on hid_output_raw_report
hid_out_raw_report is going to be obsoleted as it is not part of the
unified HID low level transport documentation
(Documentation/hid/hid-transport.txt)

To do so, we need to introduce two new quirks:
* HID_QUIRK_NO_OUTPUT_REPORTS_ON_INTR_EP: this quirks prevents the
  transport driver to use the interrupt channel to send output report
  (and thus force to use HID_REQ_SET_REPORT command)
* HID_QUIRK_SKIP_OUTPUT_REPORT_ID: this one forces usbhid to not
  include the report ID in the buffer it sends to the device through
  HID_REQ_SET_REPORT in case of an output report

This also fixes a regression introduced in commit 3a75b24949
(HID: hidraw: replace hid_output_raw_report() calls by appropriates ones).
The hidraw API was not able to communicate with the PS3 SixAxis
controllers in USB mode.

Benjamin Tissoires 595e9276ce HID: do not init input reports for Win 8 multitouch devices
Some multitouch screens do not like to be polled for input reports.
However, the Win8 spec says that all touches should be sent during
each report, making the initialization of reports unnecessary.
The Win7 spec is less precise, so do not use this for those devices.

Add the quirk HID_QUIRK_NO_INIT_INPUT_REPORTS so that we do not have to
introduce a quirk for each problematic device. This quirk makes the driver
behave the same way the Win 8 does. It actually retrieves the features,
but not the inputs.

David Herrmann 60682284e4 HID: usbhid: update LED fields unlocked
Report fields can be updated from HID drivers unlocked via
hid_set_field(). It is protected by input_lock in HID core so only a
single input event is handled at a time. USBHID can thus update the field
unlocked and doesn't conflict with any HID vendor/device drivers. Note,
many HID drivers make heavy use of hid_set_field() in that way.

But usbhid also schedules a work to gather multiple LED changes in a
single report. Hence, we used to lock the LED field update so the work can
read a consistent state. However, hid_set_field() only writes a single
integer field, which is guaranteed to be allocated all the time. So the
worst possible race-condition is a garbage read on the LED field.

Therefore, there is no need to protect the update. In fact, the only thing
that is prevented by locking hid_set_field(), is an LED update while the
scheduled work currently writes an older LED update out. However, this
means, a new work is scheduled directly when the old one is done writing
the new state to the device. So we actually _win_ by not protecting the
write and allowing the write to be combined with the current write. A new
worker is still scheduled, but will not write any new state. So the LED
will not blink unnecessarily on the device.

Assume we have the LED set to 0. Two request come in which enable the LED
and immediately disable it. The current situation with two CPUs would be:

  usb_hidinput_input_event()       |      hid_led()
  ---------------------------------+----------------------------------
    spin_lock(&usbhid->lock);
    hid_set_field(1);
    spin_unlock(&usbhid->lock);
    schedule_work(...);
                                      spin_lock(&usbhid->lock);
                                      __usbhid_submit_report(..1..);
                                      spin_unlock(&usbhid->lock);
    spin_lock(&usbhid->lock);
    hid_set_field(0);
    spin_unlock(&usbhid->lock);
    schedule_work(...);
                                      spin_lock(&usbhid->lock);
                                      __usbhid_submit_report(..0..);
                                      spin_unlock(&usbhid->lock);

With the locking removed, we _might_ end up with (look at the changed
__usbhid_submit_report() parameters in the first try!):

  usb_hidinput_input_event()       |      hid_led()
  ---------------------------------+----------------------------------
    hid_set_field(1);
    schedule_work(...);
                                      spin_lock(&usbhid->lock);
    hid_set_field(0);
    schedule_work(...);
                                      __usbhid_submit_report(..0..);
                                      spin_unlock(&usbhid->lock);

                                      ... next work ...

                                      spin_lock(&usbhid->lock);
                                      __usbhid_submit_report(..0..);
                                      spin_unlock(&usbhid->lock);

As one can see, we no longer send the "LED ON" signal as it is disabled
immediately afterwards and the following "LED OFF" request overwrites the
pending "LED ON".

It is important to note that hid_set_field() is not atomic, so we might
also end up with any other value. But that doesn't matter either as we
_always_ schedule the next work with a correct value and schedule_work()
acts as memory barrier, anyways. So in the worst case, we run
__usbhid_submit_report(..<garbage>..) in the first case and the following
__usbhid_submit_report() will write the correct value. But LED states are
booleans so any garbage will be converted to either 0 or 1 and the remote
device will never see invalid requests.

Why all this? It avoids any custom locking around hid_set_field() in
usbhid and finally allows us to provide a generic hidinput_input_event()
handler for all HID transport drivers.
