Bugzilla: N/A
Upstream-status: queued in NFS git tree (for 3.13/3.14?)
Currently, the client will attempt to use krb5i in the SETCLIENTID call
even if rpc.gssd isn't running. 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.

rpc.gssd expects to see an "info" file in each clntXX dir. Since adding
the dummy gssd pipe, users that run rpc.gssd see a lot of these messages
spamming the logs:
rpc.gssd[508]: ERROR: can't open /var/lib/nfs/rpc_pipefs/gssd/clntXX/info: No such file or directory
rpc.gssd[508]: ERROR: failed to read service info

Bugzilla: N/A
Upstream-status: queued in NFS git tree (for 3.13/3.14?)
rpc.gssd will naturally hold open any pipe named */clnt*/gssd that shows
up under rpc_pipefs. That behavior gives us a reliable mechanism to tell
whether it's actually running or not.
Create a new toplevel "gssd" directory in rpc_pipefs when it's mounted.
Under that directory create another directory called "clntXX", and then
within that a pipe called "gssd".
We'll never send an upcall along that pipe, and any downcall written to
it will just return -EINVAL.

Bugzilla: N/A
Upstream-status: queued in NFS git tree (for 3.13/3.14?)
Now that we have a more reliable method to tell if gssd is running, we
can replace the sn->gssd_running flag with a function that will query to
see if it's up and running.
There's also no need to attempt an upcall that we know will fail, so
just return -EACCES if gssd isn't running. Finally, fix the warn_gss()
message not to claim that that the upcall timed out since we don't
necesarily perform one now when gssd isn't running, and remove the
extraneous newline from the message.
