| 38 | /* |
| 39 | * nfs version 2 and 3 server calls to vnode ops |
| 40 | * - these routines generally have 3 phases |
| 41 | * 1 - break down and validate rpc request in mbuf list |
| 42 | * 2 - do the vnode ops for the request |
| 43 | * (surprisingly ?? many are very similar to syscalls in vfs_syscalls.c) |
| 44 | * 3 - build the rpc reply in an mbuf list |
| 45 | * nb: |
| 46 | * - do not mix the phases, since the nfsm_?? macros can return failures |
| 47 | * on a bad rpc or similar and do not do any vrele() or vput()'s |
| 48 | * |
| 49 | * - the nfsm_reply() macro generates an nfs rpc reply with the nfs |
| 50 | * error number iff error != 0 whereas |
| 51 | * returning an error from the server function implies a fatal error |
| 52 | * such as a badly constructed rpc request that should be dropped without |
| 53 | * a reply. |
| 54 | * For Version 3, nfsm_reply() does not return for the error case, since |
| 55 | * most version 3 rpcs return more than the status for error cases. |
