2020-10-15Merge branch 'for-5.9/upstream-fixes' into for-linusJiri Kosina
- "heartbeat" report fix for several Wacom devices - Lenovo X1 Tablet support improvements - new device IDs - bounds checking fix in hid-roccat - stylus battery reporting fix
2020-09-09HID: roccat: add bounds checking in kone_sysfs_write_settings()Dan Carpenter
This code doesn't check if "settings->startup_profile" is within bounds and that could result in an out of bounds array access. What the code does do is it checks if the settings can be written to the firmware, so it's possible that the firmware has a bounds check? It's safer and easier to verify when the bounds checking is done in the kernel.

2010-05-25HID: roccat: propagate special events of roccat hardware to userspaceStefan Achatz
Module roccat is a char device used to report special events of roccat hardware to userland. These events include requests for on-screen-display of profile or dpi settings or requests for execution of macro sequences that are not stored in device. The information in these events depends on hid device implementation and contains data that is not available in a single hid event or else hidraw could have been used. It is inspired by hidraw, but uses only one circular buffer for all readers. The device is as generic as possible so that the functionality is usable by all (kone and upcomming) roccat device drivers.

2010-03-22HID: add driver for Roccat Kone gaming mouseStefan Achatz
This Patch adds support for Kone gaming mouse from Roccat. It provides access to profiles, settings, firmware, weight, actual settings etc. through sysfs attributes. Event handling of this mouse differs from standard hid behaviour in that tilt button press is reported in each move event which results in strange behaviour if not handled by the driver. This is a heavily reworked version of the previously introduced driver. The changes include most of the previously raised concerns, memory leak and other fixes, code cleanups, adoption of additional achieved knowlege about the hardware and is (IMHO) a much better version than before even when I exchanged reduced USB-IO with a bigger memory consumption. I refused to implement one mentioned point: Removing the 'just-because-we-can' attributes. Motivation: Reading the clipped in weight: I'm no gamer and can't determine the usefulness of this feature but if the manufacturer implements such a feature it might make sense to someone and I would unwillingly limit the functionality besides its such a small feature. Reading the actual profile and dpi settings: Here I can testify that one can get lost of the actual settings when switching back and forth. The manufacturers windows driver has the ability for on-screen-display of the values and there is a mouse in the market that has an lcd on the underside of it to show these values. So I think this feature makes sense not only for me and shouldn't be removed. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
