* [evdev] Add AT translated set1 scancodes for F-unlocked F1-12 keys.Vladimir Kondratyev2020-05-041-6/+6
| | | | | | | | | | | | | | | | | "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.

| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags.

* 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.

| | | | | | | | | | | | | | | | | | Move evdev_ev_kbd_event() helper from evdev to kbd.c as otherwise evdev unconditionally requires all keyboard and console stuff to be compiled into the kernel. This dependency happens as evdev_ev_kbd_event() helper references kbdsw global variable defined in kbd.c through use of kbdd_ioctl() macro. While here make all keyboard drivers respect evdev_rcpt_mask while setting typematic rate and LEDs with evdev interface.

| | | | | | | | | | | | | | | | There was report of stable/11 build failure on older versions of FreeBSD. The problem was a reference to static variable in inline function. Although fairly recent versions of clang can cope with this situation just fine there is no strict requirement to make functions in question inline, they're not in any time-critical codepath. So to keep HEAD and 11-STABLE buildable on older FreeBSDs some of the util functions were converted from inline to normal.

evdev is a generic input event interface compatible with Linux evdev API at ioctl level. It allows using unmodified (apart from header name) input evdev drivers in Xorg, Wayland, Qt. This commit has only generic kernel API. evdev support for individual hardware drivers like ukbd, ums, atkbd, etc. will be committed later. Project was started by Jakub Klama as part of GSoC 2014. Jakub's evdev implementation was later used as a base, updated and finished by Vladimir Kondratiev.
