From 0e20162ed1e9a639fc61d62c71327169fb1a1970 Mon Sep 17 00:00:00 2001 From: Andy Adamson Date: Fri, 6 Sep 2013 14:14:00 -0400 Subject: [PATCH] NFSv4.1 Use MDS auth flavor for data server connection 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 --- Reading git-format-patch failed
