+ *      Validiate permissions required for each address associated with sock
+ *      @sk. Depending on @optname, the addresses will be treated as either
+ *      for a connect or bind service. The @addrlen is calculated on each

+ *      @addrlen total length of address(s).
+ *      Return 0 on success, error on failure.
+ * @sctp_sk_clone:
+ *      Called whenever a new socket is created by accept(2) (i.e. a TCP
