We should not allow soft tasks to wait for longer than the major timeout period when waiting for a reconnect to occur. Remove the field xprt->connect_timeout since it has been obsoleted by xprt->reestablish_timeout. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Move the O_EXCL open handling into _nfs4_do_open() where it belongs. Doing so also allows us to reuse the struct fattr from the opendata. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

All we really want is the ability to retrieve the root file handle. We no longer need the ability to walk down the path, since that is now done in nfs_follow_remote_path(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

NFS Filehandles and struct fattr are really too large to be allocated on the stack. This patch adds in a couple of helper functions to allocate them dynamically instead. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

All encryption types use a confounder at the beginning of the wrap token. In all encryption types except arcfour-hmac, the confounder is the same as the blocksize. arcfour-hmac has a blocksize of one, but uses an eight byte confounder. Add an entry to the crypto framework definitions for the confounder length and change the wrap/unwrap code to use the confounder length rather than assuming it is always the blocksize.
