| | * NFS: Fix nfs_migrate_page()Trond Myklebust2009-12-101-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The call to migrate_page() will cause the page->private field to be cleared. Also fix up the locking around the page->private transfer, so that we ensure that calls to nfs_page_find_request() don't end up racing. Finally, fix up a double free bug: nfs_unlock_request() already calls nfs_release_request() for us...

| | * nfs41: Invoke RECLAIM_COMPLETE on all new client idsRicardo Labiaga2009-12-081-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NFSv4.1 spec indicates RECLAIM_COMPLETE is to be issued whenever a client establishes a new client id, not only after detecting the server has rebooted. Set the NFS4CLNT_RECLAIM_REBOOT bit after every new client id has been established. This enables us to issue RECLAIM_COMPLETE during the wrap up of the NFS4CLNT_RECLAIM_REBOOT state.

| | * NFSv41: Fix a potential state leakage when restarting nfs4_close_prepareTrond Myklebust2009-12-081-17/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if the call to nfs4_setup_sequence() in nfs4_close_prepare fails, any later retries will fail to launch an RPC call, due to the fact that the &state->flags will have been cleared. Ditto if nfs4_close_done() triggers a call to the NFSv4.1 version of nfs_restart_rpc(). We therefore move the actual clearing of the state->flags to nfs4_close_done(), when we know that the RPC call was successful. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should not assume that nfs41_init_clientid() will always want to initialise the session. If it is being called due to a server reboot, then we just want to reset the session after re-establishing the clientid. Fix this by getting rid of the 'reset' parameter in nfs4_proc_create_session(), and instead relying on whether or not the session slot table pointer is non-NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch invokes RECLAIM_COMPLETE after the client is done reclaiming state. There are interpretations of the spec that suggest that RECLAIM_COMPLETE should also be issued after a new clientid has been obtained from the server and even if there is no state to reclaim. This tells the server that the client has no state to reclaim even if the client isn't aware the server may have rebooted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implements RECLAIM_COMPLETE as an asynchronous RPC. NFS4ERR_DELAY is retried, NFS4ERR_DEADSESSION invokes the error handling but does not result in a retry, since we don't want to have a lingering RECLAIM_COMPLETE call sent in the middle of a possible new state recovery cycle. If a session reset occurs, a new wave of reclaim operations will follow, containing their own RECLAIM_COMPLETE call. We don't want a retry to get on the way of recovery by incorrectly indicating to the server that we're done reclaiming state. A subsequent patch invokes the functionality.

A typical case is a RENAME operation on an MS-Windows platform, which prevents rename while the file is open. While it is possible that such a condition is transitory, it is also very possible that the file will be held open for an extended period of time thus preventing the operation. The current behaviour of Linux/NFS is to retry the operation indefinitely. This is not appropriate - we do not expect a rename to take an arbitrary amount of time to complete. Rather, and error should be returned. The most obvious error code would be EBUSY, which is a legal at least for 'rename' and 'unlink', and accurately captures the reason for the error. This patch allows a few retries until about 2 seconds have elapsed, then returns EBUSY. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
