2008-02-07[XFS] kill unnessecary ioops indirectionLachlan McIlroy
Currently there is an indirection called ioops in the XFS data I/O path. Various functions are called by functions pointers, but there is no coherence in what this is for, and of course for XFS itself it's entirely unused. This patch removes it instead and significantly reduces source and binary size of XFS while making maintaince easier.

2008-02-07[XFS] simplify vn_revalidateChristoph Hellwig
No need to allocate a bhv_vattr_t on stack and call xfs_getattr to update a few fields in the Linux inode from the XFS inode, just do it directly. And yes, this function is in dire need of a better name and prototype, I'll do in a separate patch, though.

There is no reason to go through xfs_iomap for the BMAPI_UNWRITTEN because it has nothing in common with the other cases. Instead check for the shutdown filesystem in xfs_end_bio_unwritten and perform a direct call to xfs_iomap_write_unwritten (which should be renamed to something more sensible one day) SGI-PV: 970241 SGI-Modid: xfs-linux-melb:xfs-kern:29681a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Donald Douwsma <donaldd@sgi.com> Signed-off-by: Tim Shimmin <tes@sgi.com>

There is no reason to go into the iomap machinery just to get the right block device for an inode. Instead look at the realtime flag in the inode and grab the right device from the mount structure. I created a new helper, xfs_find_bdev_for_inode instead of opencoding it because I plan to use it in other places in the future.

2008-02-03file locks: Use wait_event_interruptible_timeout()Matthew Wilcox
interruptible_sleep_on_locked() is just an open-coded wait_event_interruptible_timeout(), with the one difference that interruptible_sleep_on_locked() doesn't bother to check the condition on which it is waiting, depending instead on the BKL to avoid the case where it blocks after the wakeup has already been called. locks_block_on_timeout() is only used in one place, so it's actually simpler to inline it into its caller.

2008-02-01NLM: tear down RPC clients in nlm_shutdown_hostsJeff Layton
It's possible for a RPC to outlive the lockd daemon that created it, so we need to make sure that all RPC's are killed when lockd is coming down. When nlm_shutdown_hosts is called, kill off all RPC tasks associated with the host. Since we need to wait until they have all gone away, we might as well just shut down the RPC client altogether.

2008-02-01nfsd: more careful input validation in nfsctl write methodsJ. Bruce Fields
Neil Brown points out that we're checking buf[size-1] in a couple places without first checking whether size is zero. Actually, given the implementation of simple_transaction_get(), buf[-1] is zero, so in both of these cases the subsequent check of the value of buf[size-1] will catch this case. But it seems fragile to depend on that, so add explicit checks for this case. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Acked-by: NeilBrown <neilb@suse.de>

2008-02-01knfsd: don't bother mapping putrootfh enoent to epermJ. Bruce Fields
Neither EPERM and ENOENT map to valid errors for PUTROOTFH according to rfc 3530, and, if anything, ENOENT is likely to be slightly more informative; so don't bother mapping ENOENT to EPERM. (Probably this was originally done because one likely cause was that there is an fsid=0 export but that it isn't permitted to this particular client. Now that we allow WRONGSEC returns, this is somewhat less likely.) In the long term we should work to make this situation less likely, perhaps by turning off nfsv4 service entirely in the absence of the pseudofs root, or constructing a pseudofilesystem root ourselves in the kernel as necessary.

2008-02-01knfsd: Support adding transports by writing portlist fileTom Tucker
Update the write handler for the portlist file to allow creating new listening endpoints on a transport. The general form of the string is: <transport_name><space><port number> For example: echo "tcp 2049" > /proc/fs/nfsd/portlist This is intended to support the creation of a listening endpoint for RDMA transports without adding #ifdef code to the nfssvc.c file. Transports can also be removed as follows: '-'<transport_name><space><port number> For example: echo "-tcp 2049" > /proc/fs/nfsd/portlist Attempting to add a listener with an invalid transport string results in EPROTONOSUPPORT and a perror string of "Protocol not supported". Attempting to remove an non-existent listener (.e.g. bad proto or port) results in ENOTCONN and a perror string of "Transport endpoint is not connected" Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Acked-by: Neil Brown <neilb@suse.de> Reviewed-by: Chuck Lever <chuck.lever@oracle.com> Reviewed-by: Greg Banks <gnb@sgi.com> Signed-off-by: J.

2008-02-01svc: Add svc API that queries for a transport instanceTom Tucker
Add a new svc function that allows a service to query whether a transport instance has already been created. This is used in lockd to determine whether or not a transport needs to be created when a lockd instance is brought up. Specifying 0 for the address family or port is effectively a wild-card, and will result in matching the first transport in the service's list that has a matching class name.

2008-02-01svc: Make close transport independentTom Tucker
Move sk_list and sk_ready to svc_xprt. This involves close because these lists are walked by svcs when closing all their transports. So I combined the moving of these lists to svc_xprt with making close transport independent. The svc_force_sock_close has been changed to svc_close_all and takes a list as an argument. This removes some svc internals knowledge from the svcs. This code races with module removal and transport addition. Thanks to Simon Holm Thøgersen for a compile fix.

2008-02-01nfsd: allow root to set uid and gid on createJ. Bruce Fields
The server silently ignores attempts to set the uid and gid on create. Based on the comment, this appears to have been done to prevent some overly-clever IRIX client from causing itself problems. Perhaps we should remove that hack completely. For now, at least, it makes sense to allow root (when no_root_squash is set) to set uid and gid. While we're there, since nfsd_create and nfsd_create_v3 share the same logic, pull that out into a separate function. And spell out the individual modifications of ia_valid instead of doing them both at once inside a conditional.

2008-02-01nfsd: Allow AIX client to read dir containing mountpointsFrank Filz
This patch addresses a compatibility issue with a Linux NFS server and AIX NFS client. I have exported /export as fsid=0 with sec=krb5:krb5i I have mount --bind /home onto /export/home I have exported /export/home with sec=krb5i The AIX client mounts / -o sec=krb5:krb5i onto /mnt If I do an ls /mnt, the AIX client gets a permission error. Looking at the network traceIwe see a READDIR looking for attributes FATTR4_RDATTR_ERROR and FATTR4_MOUNTED_ON_FILEID. The response gives a NFS4ERR_WRONGSEC which the AIX client is not expecting. Since the AIX client is only asking for an attribute that is an attribute of the parent file system (pseudo root in my example), it seems reasonable that there should not be an error. In discussing this issue with Bruce Fields, I initially proposed ignoring the error in nfsd4_encode_dirent_fattr() if all that was being asked for was FATTR4_RDATTR_ERROR and FATTR4_MOUNTED_ON_FILEID, however, Bruce suggested that we avoid calling cross_mnt() if only these attributes are requested. The following patch implements bypassing cross_mnt() if only FATTR4_RDATTR_ERROR and FATTR4_MOUNTED_ON_FILEID are called. Since there is some complexity in the code in nfsd4_encode_fattr(), I didn't want to duplicate code (and introduce a maintenance nightmare), so I added a parameter to nfsd4_encode_fattr() that indicates whether it should ignore cross mounts and simply fill in the attribute using the passed in dentry as opposed to it's parent.

2008-02-01nfsd4: fix bad seqid on lock request incompatible with open modeJ. Bruce Fields
The failure to return a stateowner from nfs4_preprocess_seqid_op() means in the case where a lock request is of a type incompatible with an open (due to, e.g., an application attempting a write lock on a file open for read), means that fs/nfsd/nfs4xdr.c:ENCODE_SEQID_OP_TAIL() never bumps the seqid as it should. The client, attempting to close the file afterwards, then gets an (incorrect) bad sequence id error. Worse, this prevents the open file from ever being closed, so we leak state.

2008-02-01nfsd4: recognize callback channel failure earlierJ. Bruce Fields
When the callback channel fails, we inform the client of that by returning a cb_path_down error the next time it tries to renew its lease. If we wait most of a lease period before deciding that a callback has failed and that the callback channel is down, then we decrease the chances that the client will find out in time to do anything about it. So, mark the channel down as soon as we recognize that an rpc has failed. However, continue trying to recall delegations anyway, in hopes it will come back up. This will prevent more delegations from being given out, and ensure cb_path_down is returned to renew calls earlier, while still making the best effort to deliver recalls of existing delegations. Also fix a couple comments and remove a dprink that doesn't seem likely to be useful. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
