| 80 | * From RFC 1831: |
| 81 | * |
| 82 | * "A record is composed of one or more record fragments. A record |
| 83 | * fragment is a four-byte header followed by 0 to (2**31) - 1 bytes of |
| 84 | * fragment data. The bytes encode an unsigned binary number; as with |
| 85 | * XDR integers, the byte order is from highest to lowest. The number |
| 86 | * encodes two values -- a boolean which indicates whether the fragment |
| 87 | * is the last fragment of the record (bit value 1 implies the fragment |
| 88 | * is the last fragment) and a 31-bit unsigned binary value which is the |
| 89 | * length in bytes of the fragment's data. The boolean value is the |
| 90 | * highest-order bit of the header; the length is the 31 low-order bits. |
| 91 | * (Note that this record specification is NOT in XDR standard form!)" |
| 92 | * |
| 93 | * The Linux RPC client always sends its requests in a single record |
| 94 | * fragment, limiting the maximum payload size for stream transports to |
| 95 | * 2GB. |
