NFS: Fix nfs_file_llseek()
After the BKL removal patches were applied to the rest of the NFS code, the BKL protection in nfs_file_llseek() is no longer sufficient to ensure that inode->i_size is read safely in generic_file_llseek_unlocked().
In order to fix the situation, we either have to replace the naked read of inode->i_size in generic_file_llseek_unlocked() with i_size_read(), or the whole thing needs to be executed under the inode->i_lock; In order to avoid disrupting other filesystems, avoid touching generic_file_llseek_unlocked() for now...

NFS: Add options for finer control of the lookup cache
Add the flag NFS_MOUNT_LOOKUP_CACHE_NONEG to turn off the caching of negative dentries. In reality what we do is to force nfs_lookup_revalidate() to always discard negative dentries.
Add the flag NFS_MOUNT_LOOKUP_CACHE_NONE for enforcing stricter revalidation of dentries. It forces the revalidate code to always do a lookup instead of just checking the cached mtime of the parent directory.

The point of introducing text-based mounts was to allow us to add functionality without having to worry about legacy binary mount formats. The mask should be there in order to ensure that binary formats don't start enabling features that they cannot support. There is no justification for applying it to the text mount path.

NFS: Fix the NFS attribute update
Currently nfs_refresh_inode() will only update the inode metadata if it sees that the RPC call that returned the nfs_fattr was started after the last update of the inode. This means that if we have parallel RPC calls to the same inode (when sending WRITE calls, for instance), we may often miss updates.
This patch attempts to recover those missed updates by also accepting them if the ctime in the nfs_fattr is more recent than the inode's cached ctime. It also recovers the case where the file size has increased, but the ctime has not been updated due to limited ctime resolution.

NFS: Convert __nfs_revalidate_inode() to use nfs_refresh_inode()
In the case where there are parallel RPC calls to the same inode, we may receive stale metadata due to the lack of ordering, hence the sanity checking of metadata in nfs_refresh_inode(). Currently, __nfs_revalidate_inode() is calling nfs_update_inode() directly, without any further sanity checks, and hence may end up setting the inode up with stale metadata.
Fix is to use nfs_refresh_inode() instead of nfs_update_inode().

nfs: authenticated deep mounting
Allow mount to do authenticated mounts below the root of the exported tree. The wording in RFC 2623, sec 2.3.2. allows fsinfo with UNIX authentication on the root of the export. Mounts are not always done on the root of the exported tree. Especially autoumounts often mount below the root of the exported tree. Some server implementations (justly) require full authentication for the so-called deep mounts. The old code used AUTH_SYS only. This caused deep mounts to fail on systems requiring stronger authentication.. The client should try both authentication types and use the first one that succeeds. This method was already partially implemented. This patch completes the implementation for NFS2 and NFS3. This patch was developed to allow Debian systems to automount home directories on Solaris servers with krb5 authentication.

NFS: SETCLIENTID truncates client ID and netid
The sc_name field is currently 56 bytes long. This is not large enough to hold a pair of IPv6 addresses, the authentication type, the protocol name, and a uniquifier number. The maximum possible size of the name string using IPv6 addresses is just under 110 bytes, so I increased the size of the sc_name field to accomodate this maximum.
In addition, the strings in the nfs4_setclientid structure are constructed with scnprintf(), which wants to terminate its output with '\0'. The sc_netid field was large enough only for a three byte netid string and a '\0' so inet6 netids were being truncated. Perhaps we don't need the overhead of scnprintf() to do a simple string copy, but I fixed this by increasing the size of the buffer by one byte.
Since all three of the string buffers in nfs4_setclientid are constructed with scnprintf(), I increased the size of all three by one byte to document the requirement, although I don't think either the universal address field or the name field will be so small that these strings get truncated in this way.
The size of the Linux client's client ID on the wire will be larger than before. RFC 3530 suggests the size limit for client IDs is 1024, and we are still well below that.

SUNRPC: Fix autobind on cloned rpc clients
Despite the fact that cloned rpc clients won't have the cl_autobind flag set, they may still find themselves calling rpcb_getport_async(). For this to happen, it suffices for a _parent_ rpc_clnt to use autobinding, in which case any clone may find itself triggering the !xprt_bound() case in call_bind().
The correct fix for this is to walk back up the tree of cloned rpc clients, in order to find the parent that 'owns' the transport, either because it has clnt->cl_autobind set, or because it originally created the transport...

NFS: Client mounts hang when exported directory do not exist
This patch fixes a regression that was introduced by the string based mounts.
nfs_mount() statically returns -EACCES for every error returned by the remote mounted. This is incorrect because -EACCES is an non-fatal error to the mount.nfs command. This error causes mount.nfs to retry the mount even in the case when the exported directory does not exist.
This patch maps the errors returned by the remote mountd into valid errno values, exactly how it was done pre-string based mounts. By returning the correct errno enables mount.nfs to do the right thing.

sunrpc: fix oops in rpc_create when the mount namespace is unshared
On a system with nfs mounts, if a task unshares its mount namespace, a oops can occur when the system is rebooted if the task is the last to unreference the nfs mount. It will try to create a rpc request using utsname() which has been invalidated by free_nsproxy().
The patch fixes the issue by using the global init_utsname() which is always valid. the capability of identifying rpc clients per uts namespace stills needs some extra work so this should not be a problem.
