HID: i2c-hid: check if device is there before really probing

2018-08-03T05:50:34Z

[ Upstream commit b3a81b6c4fc6730ac49e20d789a93c0faabafc98 ] On many Chromebooks touch devices are multi-sourced; the components are electrically compatible and one can be freely swapped for another without changing the OS image or firmware. To avoid bunch of scary messages when device is not actually present in the system let's try testing basic communication with it and if there is no response terminate probe early with -ENXIO.

HID: hiddev: fix potential Spectre v1

2018-07-11T14:29:20Z

commit 4f65245f2d178b9cba48350620d76faa4a098841 upstream. uref->field_index, uref->usage_index, finfo.field_index and cinfo.index can be indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/hid/usbhid/hiddev.c:473 hiddev_ioctl_usage() warn: potential spectre issue 'report->field' (local cap) drivers/hid/usbhid/hiddev.c:477 hiddev_ioctl_usage() warn: potential spectre issue 'field->usage' (local cap) drivers/hid/usbhid/hiddev.c:757 hiddev_ioctl() warn: potential spectre issue 'report->field' (local cap) drivers/hid/usbhid/hiddev.c:801 hiddev_ioctl() warn: potential spectre issue 'hid->collection' (local cap) Fix this by sanitizing such structure fields before using them to index report->field, field->usage and hid->collection Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

HID: i2c-hid: Fix "incomplete report" noise

2018-07-11T14:29:20Z

commit ef6eaf27274c0351f7059163918f3795da13199c upstream. Commit ac75a041048b ("HID: i2c-hid: fix size check and type usage") started writing messages when the ret_size is <= 2 from i2c_master_recv. However, my device i2c-DLL07D1 returns 2 for a short period of time (~0.5s) after I stop moving the pointing stick or touchpad. It varies, but you get ~50 messages each time which spams the log hard. [ 95.925055] i2c_hid i2c-DLL07D1:01: i2c_hid_get_input: incomplete report (83/2) This has also been observed with a i2c-ALP0017. [ 1781.266353] i2c_hid i2c-ALP0017:00: i2c_hid_get_input: incomplete report (30/2) Only print the message when ret_size is totally invalid and less than 2 to cut down on the log spam.

HID: wacom: Correct logical maximum Y for 2nd-gen Intuos Pro large

2018-06-26T00:06:33Z

commit d471b6b22d37bf9928c6d0202bdaaf76583b8b61 upstream. The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains a typo which defines an incorrect logical maximum Y value. This causes a small portion of the bottom of the tablet to become unusable (both because the area is below the "bottom" of the tablet and because 'wacom_wac_event' ignores out-of-range values). It also results in a skewed aspect ratio. To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites the data with the correct value.

HID: intel_ish-hid: ipc: register more pm callbacks to support hibernation

2018-06-26T00:06:33Z

commit ebeaa367548e9e92dd9374b9464ff6e7d157117b upstream. Current ISH driver only registers suspend/resume PM callbacks which don't support hibernation (suspend to disk). Basically after hiberation, the ISH can't resume properly and user may not see sensor events (for example: screen rotation may not work). User will not see a crash or panic or anything except the following message in log: hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device So this patch adds support for S4/hiberbation to ISH by using the SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend and resume functions will now be used for both suspend to RAM and hibernation. If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend and resume related functions won't be used, so mark them as __maybe_unused to clarify that this is the intended behavior, and remove #ifdefs for power management.

[ Upstream commit a230cd52b8a2be39cd6e9a13b3e62af57f21372a ] The IBM/Lenovo Scrollpoint mice feature a trackpoint-like stick instead of a scrolling wheel capable of 2-D (vertical+horizontal) scrolling. hid-generic does only expose 1-D (vertical) scrolling functionality for these mice.
