Section 5.5 lists the filehandle as being REQUIRED, and "primarily for readdir requests". What's the point of listing an attribute as REQUIRED, but not for the primary (read "only!") operation where it is useful? There is an exception allowed: if the object is a referral, then you can return NFS4ERR_MOVED in the rdattr_error (which is also a REQUIRED attribute that only applies to READDIR) if the client requests it. Otherwise, you return NFS4ERR_MOVED in the READDIR result... IOW: I strongly disagree with your argument, and repeat that your server is broken as far as the protocol goes... -- Trond Myklebust Linux NFS client maintainer NetApp Trond.Myklebust@xxxxxxxxxx www.netapp.com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
