| * Calculating the maximum XDR overhead for an NFS RPC isn't easy. | |||||
| * NFS_MAXPKTHDR is antiquated and assumes AUTH_SYS over UDP. | |||||
| * NFS_MAXXDR should be sufficient for all NFS versions over TCP. | |||||
| * It includes: | |||||
| * - Maximum RPC message header. It can include 2 400byte authenticators plus | |||||
| * a machine name of unlimited length, although it is usually relatively | |||||
| * small. | |||||
| * - XDR overheads for the NFSv4 compound. This can include Owner and | |||||
| * Owner_group strings, which are usually fairly small, but are allowed | |||||
| * to be up to 1024 bytes each. | |||||
| * 4096 is overkill, but should always be sufficient. | |||||
