FYI: running networking tests needs extra privs:
#============= su ==============
allow su self:capability2 bpf;
#============= untrusted_app ==============
allow untrusted_app self:key_socket create;
allow untrusted_app self:netlink_route_socket { bind nlmsg_readpriv };
allow untrusted_app self:packet_socket create;
But obviously we can't add the last three, and not even sure about the first.
Test: atest, TreeHugger
