| 4 | * This file describes the layout of the file handles as passed | |
| 5 | * over the wire. | |
| 6 | * | |
| 7 | * Earlier versions of knfsd used to sign file handles using keyed MD5 | |
| 8 | * or SHA. I've removed this code, because it doesn't give you more | |
| 9 | * security than blocking external access to port 2049 on your firewall. | |
