When that fails, it'll then fall back to +RPC_AUTH_UNIX. This introduced a delay when mounting if rpc.gssd isn't +running, and causes warning messages to pop up in the ring buffer. + +Check to see if rpc.gssd is running before even attempting to use krb5i +auth, and just silently skip trying to do so if it isn't. In the event +that the admin is actually trying to mount with krb5*, it will still +fail at a later stage of the mount attempt. + +Signed-off-by: Jeff Layton <jlayton@redhat.com> +Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> +--- + fs/nfs/nfs4client.c | 7 ++++++- + 1 file changed, 6 insertions(+), 1 deletion(-) + +diff --git a/fs/nfs/nfs4client.c b/fs/nfs/nfs4client.c +index b4a160a..c1b7a80 100644 +--- a/fs/nfs/nfs4client.c ++++ b/fs/nfs/nfs4client.c +@@ -10,6 +10,7 @@ + #include <linux/sunrpc/auth.h> + #include <linux/sunrpc/xprt.h> + #include <linux/sunrpc/bc_xprt.h> ++#include <linux/sunrpc/rpc_pipe_fs.h> + #include "internal.h" + #include "callback.h" + #include "delegation.h" +@@ -370,7 +371,11 @@ struct nfs_client *nfs4_init_client(struct nfs_client *clp, + __set_bit(NFS_CS_INFINITE_SLOTS, &clp->cl_flags); + __set_bit(NFS_CS_DISCRTRY, &clp->cl_flags); + __set_bit(NFS_CS_NO_RETRANS_TIMEOUT, &clp->cl_flags); +- error = nfs_create_rpc_client(clp, timeparms, RPC_AUTH_GSS_KRB5I); ++ ++ error = -EINVAL; ++ if (gssd_running(clp->cl_net)) ++ error = nfs_create_rpc_client(clp, timeparms, ++ RPC_AUTH_GSS_KRB5I); + if (error == -EINVAL) + error = nfs_create_rpc_client(clp, timeparms, RPC_AUTH_UNIX); + if (error < 0) +-- +1.8.5.3 + |
