/* |
|
* From RFC 1831: |
|
* |
|
* "A record is composed of one or more record fragments. A record |
|
* fragment is a four-byte header followed by 0 to (2**31) - 1 bytes of |
|
* fragment data. The bytes encode an unsigned binary number; as with |
|
* XDR integers, the byte order is from highest to lowest. The number |
|
* encodes two values -- a boolean which indicates whether the fragment |
|
* is the last fragment of the record (bit value 1 implies the fragment |
|
* is the last fragment) and a 31-bit unsigned binary value which is the |
|
* length in bytes of the fragment's data. The boolean value is the |
|
* highest-order bit of the header; the length is the 31 low-order bits. |
|
* (Note that this record specification is NOT in XDR standard form!)" |
|
* |
|
* The Linux RPC client always sends its requests in a single record |
|
* fragment, limiting the maximum payload size for stream transports to |
|
* 2GB. |

* Universal addresses are introduced in RFC 1833 and further spelled |
|
* out in RFC 3530. RPCBIND_MAXUADDRLEN defines a maximum byte length |
|
* of a universal address for use in allocating buffers and character |
|
* arrays. |
|
* |
|
* Quoting RFC 3530, section 2.2: |
|
* |
|
* For TCP over IPv4 and for UDP over IPv4, the format of r_addr is the |
|
* US-ASCII string: |
|
* |
|
* h1.h2.h3.h4.p1.p2 |
|
* |
|
* The prefix, "h1.h2.h3.h4", is the standard textual form for |
|
* representing an IPv4 address, which is always four octets long. |
|
* Assuming big-endian ordering, h1, h2, h3, and h4, are respectively, |
|
* the first through fourth octets each converted to ASCII-decimal. |
|
* Assuming big-endian ordering, p1 and p2 are, respectively, the first |
|
* and second octets each converted to ASCII-decimal. For example, if a |
|
* host, in big-endian order, has an address of 0x0A010307 and there is |
|
* a service listening on, in big endian order, port 0x020F (decimal |
|
* 527), then the complete universal address is "10.1.3.7.2.15". |
|
* |
|
* ... |
|
* |
|
* For TCP over IPv6 and for UDP over IPv6, the format of r_addr is the |
|
* US-ASCII string: |
|
* |
|
* x1:x2:x3:x4:x5:x6:x7:x8.p1.p2 |
|
* |
|
* The suffix "p1.p2" is the service port, and is computed the same way |
|
* as with universal addresses for TCP and UDP over IPv4. The prefix, |
|
* "x1:x2:x3:x4:x5:x6:x7:x8", is the standard textual form for |
|
* representing an IPv6 address as defined in Section 2.2 of [RFC2373]. |
|
* Additionally, the two alternative forms specified in Section 2.2 of |
|
* [RFC2373] are also acceptable. |
