From 4784cb51a3f66d401f8a08810231aa7dc8f44e43 Mon Sep 17 00:00:00 2001 From: Chuck Lever <chuck.lever@oracle.com> Date: Tue, 11 Sep 2007 18:00:36 -0400 Subject: SUNRPC: Retry bad rpcbind replies When a server returns a bad rpcbind reply, make rpcbind client recovery logic retry with an older protocol version. Older versions are more likely to work correctly.
