commit c63e0e370028d7e4033bd40165f18499872b5183 upstream.
This reverts commit 8af6c08830b1ae114d1a8b548b1f8b056e068887.
This patch re-adds the workaround introduced by 596264082f10dd4
which was reverted by 8af6c08830b1ae114.
The original patch 596264 was needed to overcome a situation where
the hid-core would drop incoming reports while probe() was being
executed.
This issue was solved by c849a6143bec520af which added
hid_device_io_start() and hid_device_io_stop() that enable a specific
hid driver to opt-in for input reports while its probe() is being
executed.
Commit a9dd22b730857347 modified hid-logitech-dj so as to use the
functionality added to hid-core. Having done that, workaround 596264
was no longer necessary and was reverted by 8af6c08.
We now encounter a different problem that ends up 'again' thwarting
the Unifying receiver enumeration. The problem is time and usb controller
dependent. Ocasionally the reports sent to the usb receiver to start
the paired devices enumeration fail with -EPIPE and the receiver never
gets to enumerate the paired devices.
With dcd9006b1b053c7b1c the problem was "hidden" as the call to the usb
driver became asynchronous and none was catching the error from the
failing URB.
As the root cause for this failing SET_REPORT is not understood yet,
-possibly a race on the usb controller drivers or a problem with the
Unifying receiver- reintroducing this workaround solves the problem.
Overall what this workaround does is: If an input report from an
unknown device is received, then a (re)enumeration is performed.

commit d4b1bba76171cb783e32441b28462fe841073ed8 upstream.
Most of the hid sensor field size is reported in report_size field
in the report descriptor. For rotation fusion sensor the quaternion
data is 16 byte field, the report size was set to 4 and report
count field is set to 4. So the total size is 16 bytes. But the current
driver has a bug and not taking account for report count field. This
causes user space to see only 4 bytes of data sent via IIO interface.
The number of bytes in a field needs to take account of report_count
field. Need to multiply report_size and report_count to get total
number of bytes.

commit 95d50b6c5e18ff7351c5f2a6ff53afaed5f7e664 upstream.
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 139ebe8 ("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:
fe6065d HID: add multi-input quirk for eGalax Touchcontroller
77933c3 Merge branch 'egalax' into for-linus
ebd11fe HID: Add quirk for eGalax touch controler.
d34c4aa 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.

commit 80897aa787ecd58eabb29deab7cbec9249c9b7e6 upstream.
UHID allows short writes so user-space can omit unused fields. We
automatically set them to 0 in the kernel. However, the 64/32 bit
compat-handler didn't do that in the UHID_CREATE fallback. This will
reveal random kernel heap data (of random size, even) to user-space.

commit 19872d20c890073c5207d9e02bb8f14d451a11eb upstream.
udev has this nice feature of creating "dead" /dev/<node> device-nodes if
it finds a devnode:<node> modalias. Once the node is accessed, the kernel
automatically loads the module that provides the node. However, this
requires udev to know the major:minor code to use for the node. This
feature was introduced by:
commit 578454ff7eab61d13a26b568f99a89a2c9edc881
Author: Kay Sievers <kay.sievers@vrfy.org>
Date: Thu May 20 18:07:20 2010 +0200
driver core: add devname module aliases to allow module on-demand auto-loading
However, uhid uses dynamic minor numbers so this doesn't actually work. We
need to load uhid to know which minor it's going to use.
Hence, allocate a static minor (just like uinput does) and we're good
to go.

commit 27ce405039bfe6d3f4143415c638f56a3df77dca upstream.
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.

commit 212a871a3934beccf43431608c27ed2e05a476ec upstream.
This changes puts the commit 4fe9f8e203f back in place
with the fixes for slab corruption because of the commit.
When a device is unplugged, wait for all processes that
have opened the device to close before deallocating the device.
This commit was solving kernel crash because of the corruption in
rb tree of vmalloc. The rootcause was the device data pointer was
geting excessed after the memory associated with hidraw was freed.
The commit 4fe9f8e203f was buggy as it was also freeing the hidraw
first and then calling delete operation on the list associated with
that hidraw leading to slab corruption.

commit 1cde501bb4655e98fb832194beb88ac73be5a05d upstream.
When picolcd is switched into bootloader mode (for FW flashing) make
sure not to try to dereference NULL-pointers of feature-devices during
unplug/unbind.
This fixes following BUG:

commit 43622021d2e2b82ea03d883926605bdd0525e1d1 upstream.
The "Report ID" field of a HID report is used to build indexes of
reports. The kernel's index of these is limited to 256 entries, so any
malicious device that sets a Report ID greater than 255 will trigger
memory corruption on the host:

commit 06bb5219118fb098f4b0c7dcb484b28a52bf1c14 upstream.
Some devices of the "Speedlink VAD Cezanne" model need more aggressive fixing
than already done.
I made sure through testing that this patch would not interfere with the proper
working of a device that is bug-free. (The driver drops EV_REL events with
abs(val) >= 256, which are not achievable even on the highest laser resolution
hardware setting.)

A recent patch (9d9a04ee) added support for the new machine, but got
the sequence of USB ids wrong. Reports from both Ian and Linus T show
that the 0x0291 id is for ISO, not ANSI, which should have the missing
number 0x0290. This patchs moves the three numbers accordingly, fixing
the problem.

mt_free_input_name() was never called during .remove():
hid_hw_stop() removes the hid_input items in hdev->inputs, and so the
list is therefore empty after the call. In the end, we never free the
special names that has been allocated during .probe().
Restore the original name before freeing it to avoid acessing already
freed pointer.
This fixes a regression introduced by 49a5a827a ("HID: multitouch: append " Pen" to
the name of the stylus input")

Commit 2353f2bea ("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.
