Description

The way that this function works, if it fails to find an ip_stack for the global zone, it would end up leaking the netstack associated with it. While it's rare, it seems like this could leak a netstack reference, though it's only for the global zone, which likely will never be destroyed until shutdown and even then, it's pretty rare not to have the ip stack.
