intel-mei is a new interface in snapd 2.38 to allow access to /dev/mei* devices.
I’m trying to use this interface in Ubuntu 16.04.
With “/dev/mei[0-9]+ rw,” line in the AppArmor profile the plug does not work, the AppArmor returns “DENIED”.
If I change the line to “/dev/mei[0-9] rw,” it started to work.
What am I missing here?
Note, that I use it from systemd-started service running under root.
