From e188c214f487c9783ab3ae3e987d9a98b9298dfb Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 14 Jul 2009 16:21:01 -0400 Subject: [PATCH] getport: RPC_PROGNOTREGISTERED is a permanent error rpcbind returns RPC_PROGNOTREGISTERED if it knows for certain that an RPC program is not supported for a given transport. This is a permanent and authoritative error, so the library's rpcbind query API should never retry the query -- it will only get the same answer. A similar change was submitted for libtirpc. Unlike rpcb_getaddr(3t), mount.nfs's rpcbind client only retries once (with RPCB3PROC_GETADDR), but an extra TCP socket in this case would leave another port in TIME_WAIT. It's infrequent enough, but might as well get rid of it.
