In preparation for supporting NFSv2 and NFSv3 mount option handling in the kernel NFS client, convert mount_clnt.c to be a permanent part of the NFS client, instead of built only when CONFIG_ROOT_NFS is enabled. In addition, we also replace the "struct sockaddr_in *" argument with something more generic, to help support IPv6 at some later point.

A couple of callers just use a stringified IP address for the rpc client's hostname. Move the logic for constructing this into rpc_create(), so it can be shared. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Clean up, for consistency. Rename rpcb_getport as rpcb_getport_async, to match the naming scheme of rpcb_getport_sync. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

In preparation for handling NFS mount option parsing in the kernel, rename rpcb_getport_external as rpcb_get_port_sync, and make it available always (instead of only when CONFIG_ROOT_NFS is enabled).

This allows NFS mount requests and RPC re-binding to be interruptible if the server isn't responding. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Refactor NFSv4 mount processing to break out mount data validation in the same way it's broken out in the NFSv2/v3 mount path. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Move error handling code out of the main code path. The switch statement was also improperly indented, according to Documentation/CodingStyle. This prepares nfs_validate_mount_data for the addition of option string parsing. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

NFS and NFSv4 mounts can now share server address sanity checking. And, it provides an easy mechanism for adding IPv6 address checking at some later point.

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>

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>

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>

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>

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>

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>

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>

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>

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>

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>
