Subject: [PATCH 18/23] rpcinfo ip_ping: clean up client ping/create/destroy
|
|
|
|
The code doing the actual RPC NULL calls and the handling of
|
|
VERSMISMATCH was a bit convoluted. We would destroy and re-create
|
|
the client handle, and sometimes the associated file descriptor
|
|
would be closed and sometimes not.
|
|
|
|
Clean this up by introducing a new function ip_ping_one, which
|
|
does the actual NULL call to the indicated program version without
|
|
destroying the client handle, ever.
|
|
