[Bug 1404762] Re: apparmor profile usr.sbin.clamd does not allow ScanOnAccess via fanotify

 

Now, that on-access scan seems to be working, I tried some cases:
No detections when I copied some Eicar files around in subfolders of /home/hartwig. However, I got a detection when I placed an Eicar file directly into that folder (mentioned in /var/log/clamav/clamav.log). It looks like that only the folder mentioned in the OnAccessIncludePath parameter is scanned, but no subfolders. Any way to include subfolders?

However, this behaviour does not seem to be connected to apparmor, so it
is off-topic for this bug. I put my observations into the original
clamav question

Title:
  apparmor profile usr.sbin.clamd does not allow ScanOnAccess via
  fanotify

Status in apparmor package in Ubuntu:
  Confirmed

Bug description:
  I tried to enable the ScanOnAccess option in /etc/clamav.conf to get
  on-access scanning.

  Doing so, /var/log/clamav/clamav.log tells me:
  ERROR: ScanOnAccess: fanotify_init failed: Operation not permitted
  ScanOnAccess: clamd must be started by root

  Setting User to root in /etc/clamav/clamd.conf
  makes the clamav-daemon to fail with

  service clamav-daemon start
   * Starting ClamAV daemon clamd
  ERROR: initgroups() failed.

  I had to disable the apparmor.profile with a
  cd /etc/apparmor.d/disable
  ln -s ./../usr.sbin.clamd

  Then, the "ERROR: initgroups() failed." disappears.

  The apparmor itself came via apt-get packages. I did not edit it.
