Certain devices with class HID, protocol None did not work with the HID
driver at one point, and as a result were bound to usbtouchscreen
instead as of commit 139ebe8d ("Input: usbtouchscreen - fix eGalax HID
ignoring").  This change was prompted by the following report:

https://lkml.org/lkml/2009/1/25/127

Unfortunately, the device mentioned in this report is no longer
available for testing.

We've recently discovered that some devices with class HID, protocol
None do not work with usbtouchscreen, but do work with usbhid.  Here is
the report that made this evident:

http://comments.gmane.org/gmane.linux.kernel.input/31710

Driver binding for these devices has flip-flopped a few times, so both
of the above reports were regressions.

This situation would appear to leave us with no easy way to bind every
device to the right driver.  However, in my own testing with several
devices I have not found a device with class HID that does not work with
the current HID driver.  It is my belief that changes to the HID driver
since the original report have likely fixed the issue(s) that made it
unsuitable at the time, and that we should prefer it over usbtouchscreen
for these devices.  In particular, HID quirks affecting these devices
were added/removed in the following commits since then:

fe6065dc HID: add multi-input quirk for eGalax Touchcontroller
77933c35 Merge branch 'egalax' into for-linus
ebd11fec HID: Add quirk for eGalax touch controler.
d34c4aa4 HID: add no-get quirk for eGalax touch controller

This patch makes the HID driver no longer ignore eGalax/D-Wav/EETI
devices with class HID.  If there are in fact devices with class HID
that still do not work with the HID driver, we will see another round of
regressions.  In that case I propose we investigate why the device is
not working with the HID driver rather than re-introduce regressions for
functioning HID devices by again binding them to usbtouchscreen.

The corresponding change to usbtouchscreen will be made separately.

Revert some changes done in 77463838.

Revert all changes done in hidinput_calc_abs_res as it mistakingly used
"Unit" item exponent nibbles to affect resolution value. This wasn't
breaking resolution calculation of relevant axes of any existing
devices, though, as they have only one dimension to their units and thus
1 in the corresponding nible.

Revert to reading "Unit Exponent" item value as a signed integer in
hid_parser_global to fix reading specification-complying values. This
fixes resolution calculation of devices complying to the HID standard,
including Huion, KYE, Waltop and UC-Logic graphics tablets which have
their report descriptors fixed by the drivers.

Explanations follow.

There are two "unit exponents" in HID specification and it is important
not to mix them. One is the global "Unit Exponent" item and another is
nibble values in the global "Unit" item. See 6.2.2.7 Global Items.

The "Unit Exponent" value is just a signed integer and is used to scale
the integer resolution unit values, so fractions can be expressed.

The nibbles of "Unit" value are used to select the unit system (nibble
0), and presence of a particular basic unit type in the unit formula and
its *exponent* (or power, nibbles 1-6). And yes, the latter is in two
complement and zero means absence of the unit type.

Taking the representation example of (integer) joules from the
specification:

[mass(grams)][length(centimeters)^2][time(seconds)^-2] * 10^-7

the "Unit Exponent" would be -7 (or 0xF9, if stored as a byte) and the
"Unit" value would be 0xE121, signifying:

Nibble  Part        Value   Meaning
-----   ----        -----   -------
0       System      1       SI Linear
1       Length      2       Centimeters^2
2       Mass        1       Grams
3       Time        -2      Seconds^-2

To give the resolution in e.g. hundredth of joules the "Unit Exponent"
item value should have been -9.

See also the examples of "Unit" values for some common units in the same
chapter.

However, there is a common misunderstanding about the "Unit Exponent"
value encoding, where it is assumed to be stored the same as nibbles in
"Unit" item. This is most likely due to the specification being a bit
vague and overloading the term "unit exponent". This also was and still
is proliferated by the official "HID Descriptor Tool", which makes this
mistake and stores "Unit Exponent" as such. This format is also
mentioned in books such as "USB Complete" and in Microsoft's hardware
design guides.

As a result many devices currently on the market use this encoding and
so the driver should support them.

When dealing with usage_index, be sure to properly use unsigned instead of

When working on report fields, always validate that their report_counts are

The Win 8 detection is sufficiently complex to warrant use of the full
parser code, in spite of the inferred memory usage. Therefore, we can use
the existing HID parser in hid-core for hid_scan_report() by re-using the
code from hid_open_report(). hid_parser_global, hid_parser_local and
hid_parser_reserved does not have any side effects. We just need to
reimplement the MAIN_ITEM callback to have a proper parsing without side
effects.

implement() is setting bytes in LE data stream. In case the data is not
aligned to 64bits, it reads past the allocated buffer. It doesn't really
change any value there (it's properly bitmasked), but in case that this
read past the boundary hits a page boundary, pagefault happens when
accessing 64bits of 'x' in implement(), and kernel oopses.

This happens much more often when numbered reports are in use, as the
initial 8bit skip in the buffer makes the whole process work on values
which are not aligned to 64bits.

This problem dates back to attempts in 2005 and 2006 to make implement()
and extract() as generic as possible, and even back then the problem
was realized by Adam Kroperlin, but falsely assumed to be impossible
to cause any harm:

  http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg47690.html

I have made several attempts at fixing it "on the spot" directly in
implement(), but the results were horrible; the special casing for processing
last 64bit chunk and switching to different math makes it unreadable mess.

I therefore took a path to allocate a few bytes more which will never make
it into final report, but are there as a cushion for all the 64bit math
operations happening in implement() and extract().

All callers of hid_output_report() are converted at the same time to allocate
the buffer by newly introduced hid_alloc_report_buf() helper.

Bruno noticed that the whole raw_size test can be dropped as well, as
hid_alloc_report_buf() makes sure that the buffer is always of a proper
size.

0xc0,                          // End Collection                      135

So the first input whithin this report has a count of 3 but a usage range
of 32768. So this value is obviously wrong as it should not be greater than
the report count.

This is a driver for ELO 4000/4500 devices which report themselves as
HID devices, but do not really send HID events on touch. So we
introduce a new HID 'quirk' driver with a raw_event handler where we
take care of those events.

What we need additionally is an input_configured hook, because the
device does not mention anything about PRESSURE and TOUCH in its
report descriptor, but it actually generate those. So we set the bits
in the corresponding input_dev in that hook.

Commit 2353f2be ("HID: protect hid_debug_list") introduced mutex
locking around debug_list access to prevent SMP races when debugfs
nodes are being operated upon by multiple userspace processess.

mutex is not a proper synchronization primitive though, as the hid-debug
callbacks are being called from atomic contexts.

We also have to be careful about disabling IRQs when taking the lock
to prevent deadlock against IRQ handlers.

Benjamin reports this has also been reported in RH bugzilla as bug #958935.

It looks like the manual merge 0d69a3c7 ("Merge
branches 'for-3.9/sony' and 'for-3.9/steelseries' into for-linus") accidentally
removed Sony RF receiver with USB product id 0x0374 from the "have special
driver" list, effectively nullifying a4649184
("HID: add support for Sony RF receiver with USB product id 0x0374"). Add the
device back to the list.

Accesses to hid_device->hid_debug_list are not serialized properly, which
could result in SMP concurrency issues when HID debugfs events are accessesed
by multiple userspace processess.

Serialize all the list operations by a mutex.

No semantic changes, but hid_dump_report should be in hid-debug.c, not
in hid-core.c

This patche adds PID of Japanese Natual Ergonomic Keyboard 4000. HID
NE4K driver depends on this PID for determining its quirks. F14-F18 keys
would not work without the patch.

This driver was originally written by James McKenzie, updated by
Greg Kroah-Hartman, further updated by Bastien Nocera, with suspend
support added.
I ported it to the HID subsystem, in order to simplify it a litle
and allow lirc to use it through hiddev.

More recent versions of the IR receiver are also supported through
a patch by Alex Karpenko. The patch also adds support for the 2nd
and 5th generation of the controller, and the menu key on newer
brushed metal remotes.

This adds the 2nd generation Wii Remote IDs. They have a different
Bluetooth chipset (CSR instead of Broadcom) and are more restrictive in
what they accept as input. Hence, you need up-to-date BlueZ and
Bluetooth HIDP modules to use these devices.

This patch reverts commit 0322bd39 ("usb hid quirks for Masterkit MA901 usb
radio") and adds checks in hid_ignore() for Masterkit MA901 usb radio device.
This usb radio device shares USB ID with many Atmel V-USB (and probably other)
devices so patch sorts things out by checking name, vendor, product of hid device.
