* Fix yet another panic in which wsevent_fini() ends up being called withanton2020-07-291-3/+3
| | | | | | | | | | | | NULL. This one is a race caused by clearing the me_evp member before calling routines that could end up sleeping. While here, make wsmux_mux_close() look more like the other mux close routines for increased symmetry. ok mpi@ Reported-by: syzbot+fb9ad34ba42994683850@syzkaller.appspotmail.com

* Move logic to change brightness level in reasonable steps from acpivout(4)kettenis2020-04-191-4/+6
| | | | | | | | | | | | | | | | into wsdisplay(4). This code is now exposed through wsdisplay_brightness_{step,zero,cycle} functions that can be called by any driver that handles brightnes "hotkeys". These functions take a wsdisplay(4) device pointer as their first argument, which should be provided if a clear association between events and a particular display exist. This is used in wskbd(4). Otherwise NULL can be passed and the code will direct the request at the first wsdisplay(4) that implements brightness adjustment. Tested by many. Fixes brightness keys on x395 and other thinkpads with AMD graphics. ok patrick@

| | | | | | | | | | | devices. This condition is checked early on during open but since the same routine could end up sleeping before assigning me_evp, a race against adding the same wscons device to a wsmux could be lost. This in turn can cause a NULL deference during close. ok mpi@ Reported-by: syzbot+34c3041bfd96c888c8bd@syzkaller.appspotmail.com

| | | | | | | | | | | | FIOGETOWN/SIOCGPGRP/TIOCGPGRP. Do this by determining the meaning of the ID parameter inside the sigio code. Also add cases for FIOSETOWN and FIOGETOWN where there have been TIOCSPGRP and TIOCGPGRP before. These changes allow removing the ID translation from sys_fcntl() and sys_ioctl().

* In wskbdclose(), use the same logic as in wskbdopen() to determine ifanton2019-02-011-2/+3
| | | | | | | | | | | | | the device was opened in write-only mode. Relying on me_evar being NULL does not work if the wskbd device was opened first followed by opening a wsmux device. Closing the wskbd device first at this stage would cause the wscons_event queue inherited from the wsmux device to be freed. This in turn could cause a panic if an ioctl(WSMUXIO_INJECTEVENT) command is issued to the wsmux device. ok deraadt@ visa@ Reported-by: syzbot+ed88256423ae8d882b8b@syzkaller.appspotmail.com

* Utilize sigio with wscons. The old behavior of always making the process groupanton2018-11-191-12/+11
| | | | | | | | | | | | | | of the process who opens the device the default recipient of sigio is removed as a side-effect of this change. Issuing ioctl(FIOSETOWN) is therefore mandatory in order to receive sigio, which is more consistent with other subsystems supporting sigio. This change is all made possible by the new sigio(9) API and prevents wscons from keeping a pointer to the recipient process. Usage of such pointer could cause a panic since wscons is not inform on process deallocation, leaving a dangling pointer behind. ok mpi@ visa@

Instead of defering every input of a USB console keyboard to a timeout via a queue of one element, only differ entering ddb(4) once a matching control sequenece has been typed.

| | | | | | | | | | | | | | | | | kernels: - keyboard drivers will now tell wskbd if the keyboard layout they ask for is a default value, or a value they are 100% sure of (either because your kernel has a XXXKBD_LAYOUT option, or because the driver can tell the keyboard layout, e.g. by the country code on USB keyboards which provide it, such as Sun's) - when attaching a keyboard with a non-default layout, the layout will become the default layout of the mux for new keyboard attachments if the mux doesn't have a layout set already. - when changing the keyboard layout of a particular keyboard with an ioctl (i.e. using kbd(8) or wsconsctl(8)), the layout will become the default layout of the mux for new keyboard attachments. ok mpi@
