nfs4: copy acceptor name from context to nfs_client

2014-07-12T22:41:25Z

The current CB_COMPOUND handling code tries to compare the principal name of the request with the cl_hostname in the client. This is not guaranteed to ever work, particularly if the client happened to mount a CNAME of the server or a non-fqdn. Fix this by instead comparing the cr_principal string with the acceptor name that we get from gssd. In the event that gssd didn't send one down (i.e. it was too old), then we fall back to trying to use the cl_hostname as we do today. Signed-off-by: Jeff Layton Signed-off-by: Trond Myklebust

NFS: cache parsed auth_info in nfs_server

2013-10-28T19:37:43Z

Cache the auth_info structure in nfs_server and pass these values to submounts. This lays the groundwork for supporting multiple sec= options. Signed-off-by: Weston Andros Adamson Signed-off-by: Trond Myklebust

NFS: Add basic migration support to state manager thread

2013-10-28T19:24:40Z

Migration recovery and state recovery must be serialized, so handle both in the state manager thread. Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust

NFS: Add a super_block backpointer to the nfs_server struct

2013-10-28T19:24:26Z

NFS_SB() returns the pointer to an nfs_server struct, given a pointer to a super_block. But we have no way to go back the other way. Add a super_block backpointer field so that, given an nfs_server struct, it is easy to get to the filesystem's root dentry. Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust

NFSv4: Ensure that we disable the resend timeout for NFSv4

2013-10-01T22:22:11Z

The spec states that the client should not resend requests because the server will disconnect if it needs to drop an RPC request. Signed-off-by: Trond Myklebust

NFSv4.1 Use MDS auth flavor for data server connection

2013-09-06T18:49:16Z

Commit 4edaa308 "NFS: Use "krb5i" to establish NFSv4 state whenever possible" uses the nfs_client cl_rpcclient for all state management operations, and will use krb5i or auth_sys with no regard to the mount command authflavor choice. The MDS, as any NFSv4.1 mount point, uses the nfs_server rpc client for all non-state management operations with a different nfs_server for each fsid encountered traversing the mount point, each with a potentially different auth flavor. pNFS data servers are not mounted in the normal sense as there is no associated nfs_server structure. Data servers can also export multiple fsids, each with a potentially different auth flavor. Data servers need to use the same authflavor as the MDS server rpc client for non-state management operations. Populate a list of rpc clients with the MDS server rpc client auth flavor for the DS to use. Signed-off-by: Andy Adamson Signed-off-by: Trond Myklebust

nfs4.1: Add SP4_MACH_CRED write and commit support
