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. | |||

2025 | * - loops around building the reply | |||
2026 | * if the output generated exceeds count break out of loop | |||
2027 | * - it only knows that it has encountered eof when the VOP_READDIR() | |||
2028 | * reads nothing | |||
2029 | * - as such one readdir rpc will return eof false although you are there | |||
2030 | * and then the next will return eof | |||
2031 | * - it trims out records with d_fileno == 0 | |||
2032 | * this doesn't matter for Unix clients, but they might confuse clients | |||
2033 | * for other os'. | |||
2034 | * NB: It is tempting to set eof to true if the VOP_READDIR() reads less | |||
2035 | * than requested, but this may not apply to all filesystems. For | |||
2036 | * example, client NFS does not { although it is never remote mounted | |||
2037 | * anyhow } | |||
2038 | * The alternate call nfsrv_readdirplus() does lookups as well. | |||
2039 | * PS: The NFS protocol spec. does not clarify what the "count" byte | |||
2040 | * argument is a count of.. just name strings and file id's or the | |||
2041 | * entire reply rpc or ... | |||
2042 | * I tried just file name and id sizes and it confused the Sun client, | |||
2043 | * so I am using the full rpc size now. The "paranoia.." comment refers | |||
2044 | * to including the status longwords that are not a part of the dir. | |||
