How about <NETLINK:[ROUTE]> ?
`NETLINK_' prefix comes from netlink_protocols.h.
As far as seeing the contents of netlink_protocols array,
it seems that all entries have the same prefix.
The prefix can be trimmed before build a string which will be cached:
+ if (netlink_proto) {
++ if (has_prefix (netlink_proto, "NETLINK_"))
++ netlink_proto += netlink_proto + strlen ("NETLINK_");
+ if (asprintf(&details, "%s:[%s]", proto_name,
+ netlink_proto) < 0)
+ return -1;
+ } else {

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
