Title:
  apparmor profile prevents syslog-ng startup (fix included)

Status in AppArmor Profiles:
  New

Bug description:
  Tested on gentoo, syslog-ng-3.13.2, apparmor-profiles-2.11.1-r2;

  The apparmor-profile for syslog-ng prevents syslog-ng from accessing
  /dev/kmsg, which in turn leads to a failure when starting the daemon.
  This occurs when using a source similar to this one:

      source kernsrc {
          file("/proc/kmsg");
      };

  Even though the file should be accessed through /proc/kmsg, syslog-ng
  checks some conditions on /dev/kmsg before proceeding (checked with
  strace). As this file is not allowed to be read by the apparmor
  profile, syslog-ng fails to start.

  To fix this issue, simply add this permissions line to the apparmor
  profile:

      /dev/kmsg r,
