2022-03-15HID: google: extract Vivaldi hid feature mapping for use in hid-hammerStephen Boyd5-104/+167
We need to support parsing the HID device in both the Vivaldi and the Hammer drivers so that we can properly expose the function row physmap to userspace when a hammer device uses a vivaldi keyboard layout for the function row keys. Extract the feature mapping logic from the vivaldi driver into an hid specific vivaldi library so we can use it from both HID drivers. To allow more code sharing we mandate that vivaldi data must be placed at the very beginning of the driver data attached to the HID device instance.

2022-03-01HID: input: remove the need for HID_QUIRK_INVERTBenjamin Tissoires1-8/+90
HID_QUIRK_INVERT is kind of complex to deal with and was bogus. Furthermore, it didn't make sense to use a global per struct hid_device quirk for something dynamic as the current state. Store the current tool information in the report itself, and re-order the processing of the fields to enforce having all the tablet "state" fields before getting to In Range and other input fields. This way, we now have all the information whether a tool is present or not while processing In Range. This new behavior enforces that only one tool gets forwarded to userspace at the same time, and that if either eraser or invert is set, we enforce BTN_TOOL_RUBBER. Note that the release of the previous tool now happens in its own EV_SYN report so userspace doesn't get confused by having 2 tools. These changes are tested in the following hid-tools regression tests: https://gitlab.freedesktop.org/libevdev/hid-tools/-/merge_requests/127 Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Reviewed-by: Ping Cheng <ping.cheng@wacom.com> Acked-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2022-03-01HID: input: enforce Invert usage to be processed before InRangeBenjamin Tissoires1-2/+32
When a device exposes both Invert and InRange, Invert must be processed before InRange. If we keep the order of the device and we process them out of order, InRange will first set BTN_TOOL_PEN, and then Invert will set BTN_TOOL_RUBBER. Userspace knows how to deal with that situation, but fixing it in the kernel is now easier.

2022-03-01HID: core: for input reports, process the usages by priority listBenjamin Tissoires1-7/+38
Now that we have a list of fields/usages by priority order, walk through that list to process the inputs instead of using the order provided by the manufacturer. Note that this changes the way we update the values in the struct hid_field: Previously, once a field was processed, we updated the new values. Now we need to wait for the entire report to be processed to update the values. I don't think it will be an issue: because we were relying on the device ordering, there were no guarantees to have a field stored before an other. Which is why we introduced .report() in drivers to have those values updated.

2022-03-01HID: compute an ordered list of input fields to processBenjamin Tissoires1-1/+104
This will be used in a later commit: we build a list of input fields (and usage_index) that is ordered based on a usage priority. Changing the usage priority allows to re-order the processed list, meaning that we can enforce some usages to be process before others. For instance, before processing InRange in the HID tablets, we need to know if we are using the eraser (side or button). Enforcing a higher (lower number) priority for Invert allows to force the input stack to process that field before.

2022-03-01HID: uclogic: Switch to matching subreport bytesNikolai Kondrashov3-11/+15
Switch from matching UC-Logic subreport with a mask to a full value to support detecting Huion HS610 touch dial reports. Those would match the button mask otherwise.

Replace a single pen_frame_flag in struct uclogic_params with subreport_list in struct uclogic_params_pen to prepare for handling more subreports in Huion HS610.

2022-03-01HID: uclogic: Remove pen usage maskingNikolai Kondrashov3-54/+7
Remove support for pen usage masking from hid-uclogic. Disable whole interfaces instead. Most of those interfaces are useless, and if there is one which has an unused pen usage, but also has useful reports, its report descriptor should be rewritten instead. This simplifies the code and the data structures.

2022-02-25uaccess: remove CONFIG_SET_FSArnd Bergmann1-1/+1
There are no remaining callers of set_fs(), so CONFIG_SET_FS can be removed globally, along with the thread_info field and any references to it. This turns access_ok() into a cheaper check against TASK_SIZE_MAX. As CONFIG_SET_FS is now gone, drop all remaining references to set_fs()/get_fs(), mm_segment_t, user_addr_max() and uaccess_kernel().

2022-02-21HID: hid-thrustmaster: fix OOB read in thrustmaster_interruptsPavel Skripkin1-0/+6
Syzbot reported an slab-out-of-bounds Read in thrustmaster_probe() bug. The root case is in missing validation check of actual number of endpoints. Code should not blindly access usb_host_interface::endpoint array, since it may contain less endpoints than code expects. Fix it by adding missing validaion check and print an error if number of endpoints do not match expected number Fixes: c49c33637802 ("HID: support for initialization of some Thrustmaster wheels") Reported-and-tested-by: syzbot+35eebd505e97d315d01c@syzkaller.appspotmail.com Signed-off-by: Pavel Skripkin <paskripkin@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2022-02-17HID: elo: Revert USB reference countingJiri Kosina1-6/+1
Commit 817b8b9c539 ("HID: elo: fix memory leak in elo_probe") introduced memory leak on error path, but more importantly the whole USB reference counting is not needed at all in the first place, as the driver itself doesn't change the reference counting in any way, and the associated usb_device is guaranteed to be kept around by USB core as long as the driver binding exists.

2022-02-16HID: Add driver for Razer Blackwidow keyboardsJelle van der Waa4-0/+136
Add a driver to enable the macro keys (M1 - M5) by default, these are mapped to XF86Tools and XF86Launch5 - XF86Launch8. The driver remaps them by default to macro keys with an option to retain the old mapping which users most likely already use as there are many scripts to enable the macro keys available on Github and other websites.
