[PATCH] knfsd: be more selective in which sockets lockd listens on
Currently lockd listens on UDP always, and TCP if CONFIG_NFSD_TCP is set.
However as lockd performs services of the client as well, this is a problem.
If CONFIG_NfSD_TCP is not set, and a tcp mount is used, the server will not be
able to call back to lockd.
So:
- add an option to lockd_up saying which protocol is needed
- Always open sockets for which an explicit port was given, otherwise
only open a socket of the type required
- Change nfsd to do one lockd_up per socket rather than one per thread.
This
- removes the dependancy on CONFIG_NFSD_TCP
- means that lockd may open sockets other than at startup
- means that lockd will *not* listen on UDP if the only
mounts are TCP mount (and nfsd hasn't started).
The latter is the only one that concerns me at all - I don't know if this
might be a problem with some servers.
