bind, connect and sendto answered EFAULT for an address length below 2 and EAFNOSUPPORT for an AF_INET address below 16 or an AF_INET6 address below 28 bytes. FreeBSD 11.4's getsockaddr fails a length below 2 with EINVAL and above SOCK_MAXADDRLEN (255) with ENAMETOOLONG, and the protocols compare the length with sizeof(struct sockaddr_in) or sockaddr_in6 and fail with EINVAL.
