ab4684d156 NFSD: Fix nfs4_verifier memory alignment
Clean up due to code review.

The nfs4_verifier's data field is not guaranteed to be u32-aligned.
Casting an array of chars to a u32 * is considered generally
hazardous.

We can fix most of this by using a __be32 array to generate the
verifier's contents and then byte-copying it into the verifier field.

However, there is one spot where there is a backwards compatibility
constraint: the do_nfsd_create() call expects a verifier which is
32-bit aligned.  Fix this spot by forcing the alignment of the create
verifier in the nfsd4_open args structure.

Also, sizeof(nfs4_verifer) is the size of the in-core verifier data
structure, but NFS4_VERIFIER_SIZE is the number of octets in an XDR'd
verifier.  The two are not interchangeable, even if they happen to
have the same value.

62b9510cb3 nfsd: merge cookie collision fixes from ext4 tree
These changes fix readdir loops on ext4 filesystems with dir_index
turned on.  I'm pulling them from Ted's tree as I'd like to give them
some extra nfsd testing, and expect to be applying (potentially
conflicting) patches to the same code before the next merge window.

06effdbb49 nfsd: vfs_llseek() with 32 or 64 bit offsets (hashes)
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.

8546ee518c nfsd4: make sure set CB_PATH_DOWN sequence flag set
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.

508dc6e110 nfsd41: free_session/free_client must be called under the client_lock
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

4aa8913cb0 nfsd41: refactor nfs4_open_deleg_none_ext logic out of nfs4_open_delegation
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.

393d8ed80f nfsd4: purge stable client records with insufficient state
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).

1255a8f36c nfsd4: don't set cl_firststate on first reclaim in 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.

0157d021d2 SUNRPC: handle RPC client pipefs dentries by network namespace aware routines
v2:
1) "Over-put" of PipeFS mount point fixed. Fix is ugly, but allows to bisect
the patch set. And it will be removed later in the series.

This patch makes RPC clients PipeFs dentries allocations in it's owner network
namespace context.
RPC client pipefs dentries creation logic has been changed:
1) Pipefs dentries creation by sb was moved to separated function, which will
be used for handling PipeFS mount notification.
2) Initial value of RPC client PipeFS dir dentry is set no NULL now.

RPC client pipefs dentries cleanup logic has been changed:
1) Cleanup is done now in separated rpc_remove_pipedir() function, which takes
care about pipefs superblock locking.

Also this patch removes slashes from cb_program.pipe_dir_name and from
NFS_PIPE_DIRNAME to make rpc_d_lookup_sb() work. This doesn't affect
vfs_path_lookup() results in nfs4blocklayout_init() since this slash is cutted
off anyway in link_path_walk().

9b4146e855 NFSD: Change name of extended attribute containing junction
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.

b8548894bd nfsd4: be forgiving in the absence of the recovery directory
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.
