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

 

clamd starts with:
1. aa-complain clamd
2. invoke-rc.d clamav-daemon restart

No clamd entries in syslog.
audit.log after starting clamd:
type=USER_AUTH msg=audit(1428468600.638:193): pid=8314 uid=1000 auid=4294967295 ses=4294967295 msg='op=PAM:authentication acct="hartwig" exe="/usr/bin/sudo" hostname=? addr=? terminal=/dev/pts/18 res=success'

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.
