* evdev: Extend EVIOCGRAB ioctl scope to cover kbd interfaceVladimir Kondratyev2022-12-241-0/+2
| | | | | | | | | | | | of various keyboard drivers. EVIOCGRAB ioctl execution on /dev/input/event# device node gains exclusive access to this device to caller. It is used mostly for development purposes and remote control software. See e.g. https://reviews.freebsd.org/D30020 which is the reason of creation of this change. Keyboard grabbing is disabled in KDB and during panics. (cherry picked from commit 183088934a6c4384e45ac6d01c04754e0d7a991c)

* atkbd(4): Fix "hancha" and "han/yong" korean keys handling.Vladimir Kondratyev2022-12-241-1/+1
| | | | | | | | | | | | | The Korean keyboard has two keys, the Korean/Chinese and the Korean/English toggles, that generate scancodes 0xF1 and 0xF2 (respectively) when pressed, and nothing when released. They do not repeat. As Hanyong/Hancha keys are generally greater than 0x80, which is generally considered a release key, add extra preceding press key event to generate press/release pair. Swap Hanyong/Hancha key codes to match reality. (cherry picked from commit 6a26c99f827ffa9da5e23d466eeb17131fc75238)

* evdev: Add implicit mode for touch tracking.Vladimir Kondratyev2021-09-074-7/+99
| | | | | | | | | | | | In implicit mode assignment of slot number and tracking id is performed automatically on each synchronization requested by device driver. This is done with creation of intermediate buffer for multitouch events. This buffer holds untracked events until synchronization is requested by device driver. It is needed as touch assigment requires knowledges of all touch positions pushed in current and previous reports. (cherry picked from commit f76051c7dabe952b75127a8031d87d78b603be20)
* evdev: Import support for touch-tracking.Vladimir Kondratyev2021-09-072-2/+212
| | | | | | | | | | | | | | | Touch tracking is a process of assignment of unique trackingID to each initiated contact on the surface. Keeping the trackingIDs persistent across multitouch reports requires solving of so called Euclidian Bipartite Matching problem. This commit imports EBM-solver implementation based on Dinitz-Kronrod algorithm to find minimum cost matching between contacts listed in two consecutive reports.

* evdev: Make open(2) and close(3) handlers sleepable.Vladimir Kondratyev2021-01-074-67/+156
| | | | | | | | | | | | | | | | | | | | At the beginning of evdev there was a LOR between hardware driver's and evdev client list locks as they were taken in different order at driver's interrupt and evdev open()/close() handlers. The LOR was fixed with introduction of evdev_register_mtx() function which allowed to use a hardware driver's lock as evdev client list lock. While this works good with PS/2 and USB, this does not work with I2C. Unlike PS/2 and USB, I2C open()/close() handlers do unbound sleeps while waiting for I2C bus to release and while performing IO. This change uses epoch(9) for traversing evdev client list in interrupt handler to avoid the LOR thus making possible to convert evdev client list lock to sleepable sx. While here add brief locking protocol description. Reviewed by: markj Differential revision: https://reviews.freebsd.org/D27865

| | | | | | | | | | | | | | | | | "F lock" is a switch between two sets of scancodes for function keys F1-F12 found on some Logitech and Microsoft PS/2 keyboards [1]. When "F lock" is pressed, then F1-F12 act as function keys and produce usual keyscans for these keys. When "F lock" is depressed, F1-F12 produced the same keyscans but prefixed with E0. Some laptops use [2] E0-prefixed F1-F12 scancodes for non-standard keys.

This makes us much more evdev-friendly, and will prevent everyone using xorg and wayland with evdev devices (the default) from needing to change this locally. powerpc32 still uses the old value for the keyboard part, becaues the adb keyboard driver used there is not evdev compatible.

* Extract eventfilter declarations to sys/_eventfilter.hConrad Meyer2019-05-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

* evdev: export event device properties through sysctl interfaceVladimir Kondratyev2019-02-242-0/+95
| | | | | | | | | | | | | | | | | | | A big security advantage of Wayland is not allowing applications to read input devices all the time. Having /dev/input/* accessible to the user account subverts this advantage. libudev-devd was opening the evdev devices to detect their types (mouse, keyboard, touchpad, etc). This don't work if /dev/input/* is inaccessible. With the kernel exposing this information as sysctls (kern.evdev.input.*), we can work w/o /dev/input/* access, preserving the Wayland security model.
