* NFS: Clean-up: fix a compiler warning in fs/nfs/super.cChuck Lever2007-07-101-2/+2
| | | | | | | | /home/cel/linux/fs/nfs/super.c: In function 'nfs_pseudoflavour_to_name': /home/cel/linux/fs/nfs/super.c:270: warning: comparison between signed and unsigned Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Clean up error handling in nfs_get_sbChuck Lever2007-07-101-6/+8
| | | | | | | | The error return logic in nfs_get_sb now matches nfs4_get_sb, and is more maintainable. A subsequent patch will take advantage of this simplification. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Clean-up: Replace nfs_copy_user_string with strndup_userChuck Lever2007-07-101-37/+16
| | | | | | | | The new string utility function strndup_user can be used instead of nfs_copy_user_string, eliminating an unnecessary duplication of function. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Clean-up: Define macros for maximum host and export path name lengthsChuck Lever2007-07-102-3/+3
| | | | | Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Clean-up: use correct type when converting NFS blocks to local blocksChuck Lever2007-07-101-2/+2
| | | | | | | | inode->i_blocks is a blkcnt_t these days, which can be a u64 or unsigned long, depending on the setting of CONFIG_LSF. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Clean up nfs_size_to_loff_t()Chuck Lever2007-07-101-5/+3
| | | | | | | Use the same file size limit that lockd uses. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix up stateid locking...Trond Myklebust2007-07-103-20/+19
| | | | | | | We really don't need to grab both the state->so_owner and the inode->i_lock. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Clean up the callers of nfs4_open_recover_helper()Trond Myklebust2007-07-101-22/+20
| | | | | | | | Rely on nfs4_try_open_cached() when appropriate. Also fix an RCU violation in _nfs4_do_open_reclaim() Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Don't call OPEN if we already have an open stateid for a fileTrond Myklebust2007-07-101-8/+41
| | | | | | | | If we already have a stateid with the correct open mode for a given file, then we can reuse that stateid instead of re-issuing an OPEN call without violating the close-to-open caching semantics. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Check for the existence of a delegation in nfs4_open_prepare()Trond Myklebust2007-07-101-88/+107
| | | | | | | We should not be calling open() on an inode that has a delegation unless we're doing a reclaim. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Clean up _nfs4_proc_open()Trond Myklebust2007-07-101-13/+10
| | | | | | Use a flag instead of the 'data->rpc_status = -ENOMEM hack. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Allow nfs4_opendata_to_nfs4_state to return errors.Trond Myklebust2007-07-101-11/+18
| | | | Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Improve the debugging of bad sequence id errors...Trond Myklebust2007-07-102-1/+10
| | | | Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Always use the delegation if we have oneTrond Myklebust2007-07-103-36/+94
| | | | Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Clean up confirmation of sequence ids...Trond Myklebust2007-07-101-2/+3
| | | | Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Defer inode revalidation when setting up a delegationTrond Myklebust2007-07-103-5/+10
| | | | | | | | | Currently we force a synchronous call to __nfs_revalidate_inode() in nfs_inode_set_delegation(). This not only ensures that we cannot call nfs_inode_set_delegation from an asynchronous context, but it also slows down any call to open(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Use RCU to protect delegationsTrond Myklebust2007-07-102-55/+73
| | | | Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Support recalling delegations by stateid part 2Trond Myklebust2007-07-103-8/+6
| | | | Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Support recalling delegations by stateidTrond Myklebust2007-07-102-39/+51
| | | | | | | | | There appear to be some rogue servers out there that issue multiple delegations with different stateids for the same file. Ensure that when we return delegations, we do so on a per-stateid basis rather than a per-file basis. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix up a bug in nfs4_open_recover()Trond Myklebust2007-07-101-34/+31
| | | | | | Don't clobber the delegation info... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: set the delegation in nfs4_opendata_to_nfs4_stateTrond Myklebust2007-07-101-18/+16
| | | | | | | | | This ensures that nfs4_open_release() and nfs4_open_confirm_release() can now handle an eventual delegation that was returned with out open. As such, it fixes a delegation "leak" when the user breaks out of an open call. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix a bug in __nfs4_find_state_byownerTrond Myklebust2007-07-101-5/+2
| | | | | | | | The test for state->state == 0 does not tell you that the stateid is in the process of being freed. It really tells you that the stateid is not yet initialised... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix atomic open for execute...Trond Myklebust2007-07-101-1/+14
| | | | | | | | Currently we do not check for the FMODE_EXEC flag as we should. For that particular case, we need to perform an ACCESS call to the server in order to check that the file is executable. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Reduce the chances of an open_owner identifier collisionTrond Myklebust2007-07-107-67/+190
| | | | | | Currently we just use a 32-bit counter. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: nfs_increment_open_seqid should not return a valueTrond Myklebust2007-07-101-3/+3
| | | | | | It is a void function... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix underestimate of NFSv4 lookup request sizeTrond Myklebust2007-07-101-6/+11
| | | | | | Also fix up the underestimate of fs_locations Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix the underestimate of NFSv4 open request sizeTrond Myklebust2007-07-101-18/+45
| | | | | | | The maximum size depends on the filename size and a number of other elements which are currently not being counted. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix the NFSv4 owner and owner_group size estimatesTrond Myklebust2007-07-101-1/+3

* NFSv4: Don't reuse expired nfs4_state_owner structsTrond Myklebust2007-07-103-40/+0
| | | | | | That just confuses certain NFSv4 servers. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix a credential reference leak in nfs4_get_state_owner()Trond Myklebust2007-07-101-4/+2

* NFS: Replace NFS_I(inode)->req_lock with inode->i_lockTrond Myklebust2007-07-104-51/+46
| | | | | | | There is no justification for keeping a special spinlock for the exclusive use of the NFS writeback code. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Clean up _nfs4_proc_lookup() vs _nfs4_proc_lookupfh()Trond Myklebust2007-07-101-26/+9
| | | | | | | They differ only slightly in the arguments they take. Why have they not been merged? Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Suppress some noisy and unnecessary printk() calls in call_verify()Trond Myklebust2007-07-101-9/+15
| | | | | | Convert them into dprintk() calls. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Ensure RPCSEC_GSS destroys the security context when freeing a credTrond Myklebust2007-07-101-2/+58
| | | | | | | Do so by set the gc_proc field to RPC_GSS_PROC_DESTROY, and then sending a NULL RPC call. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Ensure that the struct gss_auth lifetime exceeds the credential'sTrond Myklebust2007-07-101-6/+25
| | | | | | | Add a refcount in order to ensure that the gss_auth doesn't disappear from underneath us while we're freeing up GSS contexts. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Remove the tk_auth macro...Trond Myklebust2007-07-108-29/+29
| | | | | | | | We should almost always be deferencing the rpc_auth struct by means of the credential's cr_auth field instead of the rpc_clnt->cl_auth anyway. Fix up that historical mistake, and remove the macro that propagated it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: Allow rpc_auth to run clean up before the rpc_client is destroyedTrond Myklebust2007-07-101-5/+25
| | | | | | | RPCSEC_GSS needs to be able to send NULL RPC calls to the server in order to free up any remaining GSS contexts. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
