Bug description:
apparmor is not loading for Ubuntu containers under incus. This is due
to `/lib/apparmor/rc.apparmor.functions` (18.04 uses
`/lib/apparmor/functions`):
is_container_with_internal_policy() {
# this function is sometimes called independently of
# is_apparmor_loaded(), so also define this here.
local ns_stacked_path="${SFS_MOUNTPOINT}/.ns_stacked"
local ns_name_path="${SFS_MOUNTPOINT}/.ns_name"
local ns_stacked
local ns_name
if ! [ -f "$ns_stacked_path" ] || ! [ -f "$ns_name_path" ]; then
return 1
fi
read -r ns_stacked < "$ns_stacked_path"
if [ "$ns_stacked" != "yes" ]; then
return 1
fi
# LXD and LXC set up AppArmor namespaces starting with "lxd-" and
# "lxc-", respectively. Return non-zero for all other namespace
# identifiers.
read -r ns_name < "$ns_name_path"
if [ "${ns_name#lxd-*}" = "$ns_name" ] && \
[ "${ns_name#lxc-*}" = "$ns_name" ]; then
return 1
fi
return 0
}
This can be fixed by adjusting it to have:
# LXD, LXC and incus set up AppArmor namespaces starting with "lxd-",
# "lxc-", and "incus-" respectively. Return non-zero for all other
namespace
# identifiers.
read -r ns_name < "$ns_name_path"
if [ "${ns_name#lxd-*}" = "$ns_name" ] && \
[ "${ns_name#lxc-*}" = "$ns_name" ] && \
[ "${ns_name#incus-*}" = "$ns_name" ] ; then
return 1
fi
