Hello Misc.
TL;DR: usbhidaction(1) is unveil(2)ed too strictly to run programs.
I'm running:
kern.version=OpenBSD 7.1 (GENERIC.MP) #3: Sun May 15 10:27:01 MDT 2022
r...@syspatch-71-amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Complete dmesg at the bottom.
I use usbhidaction to make some global mappings for mpd. My
usbhidaction.conf looks something like this:
/etc/usbhidaction.conf:
Consumer:Volume_Increment 1 sndioctl output.level=+0.05
Consumer:Volume_Decrement 1 sndioctl output.level=-0.05
Consumer:Mute 1 sndioctl output.mute=!
Consumer:Play/Pause 1 mpc -q toggle
Consumer:Scan_Previous_Track 1 mpc -q prev
Consumer:Scan_Next_Track 1 mpc -q next
Consumer:Random_Play 1 mpc -q random
Consumer:Stop 1 mpc -q stop
Consumer:Fast_Forward 1 mpc -q seek +10
Consumer:Rewind 1 mpc -q seek -10
----
The reason for using usbhidaction (as opposed to regular X binds) is
that i'm not always running X. My GPU freezes every now and then
(amdgpu), so most of the time I'm running X-less. I like those binds to
be consistent whether I'm running X or not, basically.
On 7.0, ucc(4) was introduced. This driver works for my usb thinkpad kb
but not with a home-made with custom firmware. Both work with
usbhidaction.
7.0, if I remember correctly, added unveil to usbhidaction, which does
its job flawlessly, as in completely blocking access to anything other
than its config file, but it also blocks access to any programs
configured in it, I think, defeating the point of usbhidaction.
The question is then: what's the best approach to solve this?
Completely removing usbhidaction's unveil call will decrease
security, so I'm sure this is not an option.
Unveiling each of the programs named in the config file. This will
work for initial setup, but if usbhidaction gets a SIGHUP it won't
be able to unveil new programs named in the config file. This in
turn forces a restart of the service, defeating the point of
reloading. However, it's still an improvement over it not working.
Fix my custom kb so it works with ucc. This I will do, as there's
obviously something wrong in how I report the keys, but I don't know
if there's a way to tell ucc what to do on keypresses. If I have mpd
and mpv running, which one should react to it? Can I map this out of
X as well?
Or, I'm using usbhidaction wrong and I should fix my setup. In which
case I'd like some pointers on how to do so.
For the time being, I disable ucc on boot and I patched the unveil calls
out of usbhidaction. It's working fine and I don't mind a few patches,
but I suspect there's a better way to deal with this.
Regards.
