I see this now on a plain, fresh install of MySQL 5.7:
[Fri Mar 31 12:50:59 2017] audit: type=1400 audit(1490957460.075:78): apparmor="DENIED" operation="open" profile="/usr/sbin/mysqld" name="/proc/4988/status" pid=4988 comm="mysqld" requested_mask="r" denied_mask="r" fsuid=112 ouid=112
As Robie notes, it's from bug 1658239.
However, this error has no noticeable effect on the running of the server. It comes up as it should, including after a service restart or a system reboot, so I don't think it's really related to this bug report.
It might be causing problems that aren't trivial to reproduce, but if so it should be fixed with the fix to apparmor upstream.
For those of you seeing issues that don't include errors when reading files in /etc/mysql, do you see anything in the journal log or MySQL error log?
