Use 32-bit or 64-bit llseek() hashes for directory offsets depending on the NFS version. NFSv2 gets 32-bit hashes only. NOTE: This patch got rather complex as Christoph asked to set the filp->f_mode flag in the open call or immediatly after dentry_open() in nfsd_open() to avoid races. Personally I still do not see a reason for that and in my opinion FMODE_32BITHASH/FMODE_64BITHASH flags could be set nfsd_readdir(), as it follows directly after nfsd_open() without a chance of races.

Make sure this is set whenever there is no callback channel. If a client does not set up a callback channel at all, then it will get this flag set from the very start. That's OK, it can just ignore the flag if it doesn't care. If a client does care, I think it's better to inform it of the problem as early as possible.

The session client is manipulated under the client_lock hence both free_session and nfsd4_del_conns must be called under this lock. This patch adds a BUG_ON that checks this condition in the respective functions and implements the missing locks. nfsd4_{get,put}_session helpers were moved to the C file that uses them so to prevent use from external files and an unlocked version of nfsd4_put_session is provided for external use from nfs4xdr.c Signed-off-by: NBenny Halevy <bhalevy@tonian.com> Signed-off-by: NJ.

Handle the case where the nfsv4.1 client asked to uprade or downgrade its delegations and server returns no delegation. In this case, op_delegate_type is set to NFS4_OPEN_DELEGATE_NONE_EXT and op_why_no_deleg is set respectively to WND4_NOT_SUPP_{UP,DOWN}GRADE Signed-off-by: NBenny Halevy <bhalevy@tonian.com> Signed-off-by: NJ.

When a 4.1 client asks for a delegation and the server returns none op_delegate_type is set to NFS4_OPEN_DELEGATE_NONE_EXT and op_why_no_deleg is set to either WND4_CONTENTION or WND4_RESOURCE. Or, if the client sent a NFS4_SHARE_WANT_CANCEL (which it is not supposed to ever do until our server supports delegations signaling), op_why_no_deleg is set to WND4_CANCELLED. Note that for WND4_CONTENTION and WND4_RESOURCE, the xdr layer is hard coded at this time to encode boolean FALSE for ond_server_will_push_deleg / ond_server_will_signal_avail.

To escape having your stable storage record purged at the end of the grace period, it's not sufficient to simply have performed a setclientid_confirm; you also need to meet the same requirements as someone creating a new record: either you should have done an open or open reclaim (in the 4.0 case) or a reclaim_complete (in the 4.1 case).

We set cl_firststate when we first decide that a client will be permitted to reclaim state on next boot. This happens: - for new 4.0 clients, when they confirm their first open - for returning 4.0 clients, when they reclaim their first open - for 4.1+ clients, when they perform reclaim_complete We also use cl_firststate to decide whether a reclaim_complete has already been performed, in the 4.1+ case. We were setting it on 4.1 open reclaims, which caused spurious COMPLETE_ALREADY errors on RECLAIM_COMPLETE from an nfs4.1 client with anything to reclaim.

When I initially wrote it, I didn't understand how lists worked so I wrote something that didn't use them. I think making a list of stateids to test is a more straightforward implementation, especially compared to especially compared to decoding stateids while simultaneously encoding a reply to the client.

As of fedfs-utils-0.8.0, user space stores all NFS junction information in a single extended attribute: "trusted.junction.nfs". Both FedFS and NFS basic junctions are stored in this one attribute, and the intention is that all future forms of NFS junction metadata will be stored in this attribute. Other protocols may use a different extended attribute. Thus NFSD needs to look only for that one extended attribute. The "trusted.junction.type" xattr is deprecated. fedfs-utils-0.8.0 will continue to attach a "trusted.junction.type" xattr to junctions, but future fedfs-utils releases may no longer do that.

If the recovery directory doesn't exist, then behavior after a reboot will be suboptimal. But it's unnecessarily harsh to then prevent the nfsv4 server from working at all. Instead just print a warning (already done in nfsd4_init_recdir()) and soldier on. Tested-by: NLior <lior@tonian.com> Signed-off-by: NJ. Bruce Fields <bfields@redhat.com>
