From d5a8620f7c8a5bcade730e2fa1224191f289fb00 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 18 Mar 2009 20:47:29 -0400 Subject: [PATCH] SUNRPC: Simplify svc_unregister() Our initial implementation of svc_unregister() assumed that PMAP_UNSET cleared all rpcbind registrations for a [program, version] tuple. However, we now have evidence that PMAP_UNSET clears only "inet" entries, and not "inet6" entries, in the rpcbind database. For backwards compatibility with the legacy portmapper, the svc_unregister() function also must work if user space doesn't support rpcbind version 4 at all. Thus we'll send an rpcbind v4 UNSET, and if that fails, we'll send a PMAP_UNSET. This simplifies the code in svc_unregister() and provides better backwards compatibility with legacy user space that does not support rpcbind version 4. We can get rid of the conditional compilation in here as well.
