AppArmor denied messages for profile="/usr/bin/ceph-mds" flooding the system log

This document (7023914) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Enterprise Storage 5.x

Situation

The system log "/var/log/messages" is flooded with messages similar to the following:

2019-06-05T12:00:00.873826+0x:x <host_name> kernel: [xxx.xxx] audit: type=1400 audit(xxx.xxx:xxx): apparmor="DENIED" operation="open" profile="/usr/bin/ceph-mds" name="/proc/<pid_number>/status" pid=<pid_number> comm="safe_timer" requested_mask="r" denied_mask="r" fsuid=xxx ouid=xxx

Resolution

Adjust the "/etc/apparmor.d/usr.bin.ceph-mds" profile to allow read for "/proc/*/stat" and "/proc/*/status".

Cause

The default AppArmor profile is missing some read access permissions.

Additional Information

To implement the change, edit the "/etc/apparmor.d/usr.bin.ceph-mds" file so the entries granting permissions are:

/usr/bin/ceph-mds mr,
/proc/*/stat r,
/proc/*/status r,

After saving the file, reload the AppArmor profiles by executing "systemctl reload apparmor".

Alternatively the YaST apparmor module can also be used to make the required changes.
