[PATCH] RPCSEC_GSS client upcall user [5/6]
This patches the RPCSEC_GSS client to make use of the upcall mechanism
that was provided by patch [3/6].
If an RPC task presents a non-uptodate credential to call_refresh(),
a user daemon is contacted by means of a dedicated rpc_pipefs pipe.
The daemon is then fed the uid for which it must establish a new RPCSEC
security context.
While the daemon goes about its business, the RPC task is put to sleep
on a wait queue in order to allow the 'rpciod' process to service other
requests. If another task wants to use the same credential, it too will
be put to sleep once it reaches call_refresh(). A timeout mechanism
ensures that requests are retried (or that 'soft' mounts fail) if the
daemon crashes / is killed.
Once the daemon has established the RPCSEC context, it writes the result
back to the pipe, causing the credential to be updated. Those RPC tasks
that were sleeping on the context are automatically woken up, and
their execution can proceed.
