The /etc/ld.so.preload file is used to list ELF shared libraries to be
loaded before the program, and this is part of the protection that
AppArmor provides. Allowing access to this file in the apparmor profile
would simply mean an additional (custom) library would need to be added
to the profile. Since the /etc/ld.so.preload file is non-standard and
system specific, it is expected that users/administrators will need to
adjust their AppArmor profiles accordingly.
Michael, NetworkManager appears to be running fine with the exception of the
extra logging. I suggest the /etc/ld.so.preload file be moved to
/etc/ld.so.preload.bak and see if that causes problems (you should probably
look inside to see why it is there in the first place). Another option is to
add the following to the /usr/lib/NetworkManager/nm-dhcp-client.action stanza
of /etc/apparmor.d/sbin.dhclient3:
deny /etc/ld.so.preload r,
and then perform:
$ sudo apparmor_parser -r /etc/apparmor.d/sbin.dhclient3
