580a775fb5 SUNRPC: Fix a NULL pointer deref in trace_svc_stats_latency()
[ Upstream commit 5c11720767f70d34357d00a15ba5a0ad052c40fe ]

Some paths through svc_process() leave rqst->rq_procinfo set to
NULL, which triggers a crash if tracing happens to be enabled.

af8db3370b SUNRPC: Trace calls to .rpc_call_done
[ Upstream commit b40887e10dcacc5e8ae3c1a99dcba20877c4831b ]

Introduce a single tracepoint that can replace simple dprintk call
sites in upper layer "rpc_call_done" callbacks. Example:

   kworker/u24:2-1254  [001]   771.026677: rpc_stats_latency:    task:00000001@00000002 xid=0x16a6f3c0 rpcbindv2 GETPORT backlog=446 rtt=101 execute=555
   kworker/u24:2-1254  [001]   771.026677: rpc_task_call_done:   task:00000001@00000002 flags=ASYNC|DYNAMIC|SOFT|SOFTCONN|SENT runstate=RUNNING|ACTIVE status=0 action=rpcb_getport_done
   kworker/u24:2-1254  [001]   771.026678: rpcb_setport:         task:00000001@00000002 status=0 port=20048

83656eacdb SUNRPC: Eliminate the RQ_AUTHERR flag
[ Upstream commit 9082e1d914f8b27114352b1940bbcc7522f682e7 ]

Now that there is an alternate method for returning an auth_stat
value, replace the RQ_AUTHERR flag with use of that new method.

c51740a8d7 SUNRPC: Add svc_rqst::rq_auth_stat
[ Upstream commit 438623a06bacd69c40c4af633bb09a3bbb9dfc78 ]

I'd like to take commit 4532608d71c8 ("SUNRPC: Clean up generic
dispatcher code") even further by using only private local SVC
dispatchers for all kernel RPC services. This change would enable
the removal of the logic that switches between
svc_generic_dispatch() and a service's private dispatcher, and
simplify the invocation of the service's pc_release method
so that humans can visually verify that it is always invoked
properly.

All that will come later.

First, let's provide a better way to return authentication errors
from SVC dispatcher functions. Instead of overloading the dispatch
method's *statp argument, add a field to struct svc_rqst that can
hold an error value.

aa29daf2f0 SUNRPC: Export svc_xprt_received()
[ Upstream commit 7dcfbd86adc45f6d6b37278efd22530cf80ab474 ]

Prepare svc_xprt_received() to be called from transport code instead
of from generic RPC server code.
