2014-11-14HID: usbhid: enable always-poll quirk for Elan TouchscreenJohan Hovold
commit bfe3c873e978d78b542a5852575dd74f4d1a5838 upstream. 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.

2014-11-14HID: input: Fix TransducerSerialNumber implementationJason Gerecke
commit 5989a55a4c9aafba8b152c6bf52244510c2b88b9 upstream. The commit which introduced TransducerSerialNumber (368c966) is missing two crucial implementation details. Firstly, the commit does not set the type/code/bit/max fields as expected later down the code which can cause the driver to crash when a tablet with this usage is connected. Secondly, the call to 'set_bit' causes MSC_PULSELED to be sent instead of the expected MSC_SERIAL. This commit addreses both issues.

2014-10-30HID: rmi: check sanity of the incoming reportBenjamin Tissoires
commit 5b65c2a0296644dd3dbdd590d6f00174d18c96b3 upstream. In the Dell XPS 13 9333, it appears that sometimes the bus get confused and corrupts the incoming data. It fills the input report with the sentinel value "ff". Synaptics told us that such behavior does not comes from the touchpad itself, so we filter out such reports here. Unfortunately, we can not simply discard the incoming data because they may contain useful information. Most of the time, the misbehavior is quite near the end of the report, so we can still use the valid part of it.

commit 8ffffd5212846b72f116f7a9572e83d580e25802 upstream. Some Wacom tablets (at least the ISDv4 found in the Lenovo X230) timeout during probe while retrieving the input reports. The only time this information is valuable is during the feature_mapping stage, so we can ask for it there and discard the generic input reports retrieval. This gives a code path closer to the wacom.ko driver when it was in the input subtree (not HID).

2014-08-21HID: logitech: perform bounds checking on device_id early enoughJiri Kosina
device_index is a char type and the size of paired_dj_deivces is 7 elements, therefore proper bounds checking has to be applied to device_index before it is used. We are currently performing the bounds checking in logi_dj_recv_add_djhid_device(), which is too late, as malicious device could send REPORT_TYPE_NOTIF_DEVICE_UNPAIRED early enough and trigger the problem in one of the report forwarding functions called from logi_dj_raw_event().

The check on report size for REPORT_TYPE_LEDS in logi_dj_ll_raw_request() is wrong; the current check doesn't make any sense -- the report allocated by HID core in hid_hw_raw_request() can be much larger than DJREPORT_SHORT_LENGTH, and currently logi_dj_ll_raw_request() doesn't handle this properly at all.

Currently rmi_probe will return -EIO if the device doesn't report that it has F11. This would indicate that something happened and the device is in the bootloader. We can recover the device using a userspace firmware update tool, but it needs access to the device through the hidraw device file. If the probe returns -EIO the hidraw device won't be created. So instead of failing the probe, just print an error message, but leave the device accessible from userspace.

2014-07-29HID: usbhid: Use flag HID_DISCONNECTED when a usb device is removedReyad Attiyat
Set disconnected flag in struct usbhid when a usb device is removed. Check for disconnected flag before sending urb requests. This prevents a kernel panic when a hid driver calls hid_hw_request() after removing a usb device.

2014-07-29HID: rmi: only bind the hid-rmi driver to the mouse interface of composite ↵Andrew Duggan
USB devices On composite HID devices there may be multiple HID devices on separate interfaces, but hid-rmi should only bind to the mouse interface. One example is the Dell Venue 11 Pro's keyboard dock which contains a composite USB device with a HID touchpad and HID keyboard on separate intefaces. Since the USB Vendor ID is Synaptic's, hid-core is currently trying to bind hid-rmi to all\of the HID devices. This patch ensures that hid-rmi only binds to the mouse interface. related bug: https://bugzilla.kernel.org/show_bug.cgi?id=80091 Signed-off-by: Andrew Duggan <aduggan@synaptics.com> Reviewed-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

their size It is possible that the hid-rmi driver could get loaded onto a device which does not have the expected report ids. This should not happen because it would indicate that the hid-rmi driver is not compatible with that device. However, if it does happen it should return an error from probe instead of dereferencing a null pointer. related bug: https://bugzilla.kernel.org/show_bug.cgi?id=80091 Signed-off-by: Andrew Duggan <aduggan@synaptics.com> Reviewed-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
