Bug Description
Am trying to get NTP to work with the kernel PPS subsystem, for high-accuracy GPS-based clocks. On startup of NTPd I see this:
Apr 1 11:18:58 doorway kernel: [ 300.387443] audit: type=1400 audit(145950593
Adding this to the usr.sbin.ntpd apparmor profile eliminated the error:
/dev/pps[0-9]* rw,
I'm not sure why ntpd needs *write* access to ppsN though, perhaps that can be improved.
