From 8a3177604b729ec3b80e43790ee978863ac7551b Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 1 Feb 2006 12:18:36 -0500 Subject: SUNRPC: Fix a lock recursion in the auth_gss downcall When we look up a new cred in the auth_gss downcall so that we can stuff the credcache, we do not want that lookup to queue up an upcall in order to initialise it. To do an upcall here not only redundant, but since we are already holding the inode->i_mutex, it will trigger a lock recursion. This patch allows rpcauth cache searches to indicate that they can cope with uninitialised credentials.
