And just to clarify, those permissions aren't necessarily being enforced
by your kernel.  The new networking permissions only get enabled if the
network_peer_controls capability is set in your policy.  That is to
prevent breakage for existing users until policy is updated to support
the new controls.  I think the necessary rules have been added to the
upstream refpolicy, but the capability hasn't been turned on yet.
