The sc_name field is currently 56 bytes long. This is not large enough to hold a pair of IPv6 addresses, the authentication type, the protocol name, and a uniquifier number. The maximum possible size of the name string using IPv6 addresses is just under 110 bytes, so I increased the size of the sc_name field to accomodate this maximum. In addition, the strings in the nfs4_setclientid structure are constructed with scnprintf(), which wants to terminate its output with '\0'. The sc_netid field was large enough only for a three byte netid string and a '\0' so inet6 netids were being truncated. Perhaps we don't need the overhead of scnprintf() to do a simple string copy, but I fixed this by increasing the size of the buffer by one byte. Since all three of the string buffers in nfs4_setclientid are constructed with scnprintf(), I increased the size of all three by one byte to document the requirement, although I don't think either the universal address field or the name field will be so small that these strings get truncated in this way. The size of the Linux client's client ID on the wire will be larger than before. RFC 3530 suggests the size limit for client IDs is 1024, and we are still well below that.
