Title:
Disconnected path errors
Status in apparmor package in Ubuntu:
Confirmed
Bug description:
The first error is that the audit message (notice the path):
type=AVC msg=audit(1448143203.902:359992): apparmor="DENIED"
operation="file_mmap" info="Failed name lookup - disconnected path"
error=-13 profile="/usr/sbin/openvpn" name="run/nscd/dbfQMsBd"
pid=25814 comm="openvpn" requested_mask="r" denied_mask="r" fsuid=0
ouid=0
appears in the audit log. The second is that aa-logprof throws an
exception on reading it:
Traceback (most recent call last):
File "/usr/sbin/aa-logprof", line 54, in
apparmor.do_logprof_pass(logmark)
File "/usr/lib/python3.4/site-packages/apparmor/aa.py", line 2289, in

severity = sev_db.rank(path, mode_to_str(mode))

raise AppArmorException("Unexpected rank input: %s" % resource)
apparmor.common.AppArmorException: 'Unexpected rank input: run/nscd/dbfQMsBd'
I've been having this problem for several years.
