        "There are certain protocols which are very common, such as TCP, UDP, IP and ICMP. IP and ICMP are on the same level: the network layer 2. There are certain precautions which are taken in order to prevent a jailed process from binding a protocol to a certain address only if the `nam` parameter is set. `nam` is a pointer to a `sockaddr` structure, which describes the address on which to bind the service. A more exact definition is that `sockaddr` \"may be used as a template for referring to the identifying tag and length of each address\". In the function `in_pcbbind_setup()`, `sin` is a pointer to a `sockaddr_in` structure, which contains the port, address, length and domain family of the socket which is to be bound. Basically, this disallows any processes from jail to be able to specify the address that does not belong to the jail in which the calling process exists."
