[libvirt] [PATCH] fixed segfault in virauth

No check for conn->uri being NULL in virAuthGetConfigFilePath (valid state) made the client segfault. This happens with fresh defalt VDSM configuration for example. The check ought to be enough as conn->uri being NULL is valid in later code. --- src/util/virauth.c | 20 +++++++++++--------- 1 files changed, 11 insertions(+), 9 deletions(-) diff --git a/src/util/virauth.c b/src/util/virauth.c index e6b1db0..2c1a4ae 100644 --- a/src/util/virauth.c +++ b/src/util/virauth.c @@ -1,7 +1,7 @@ /* * virauth.c: authentication related utility functions * - * Copyright (C) 2010 Matthias Bolte <matthias.bolte(a)googlemail.com&gt; + * Copyright (C) 2010, 2012 Matthias Bolte <matthias.bolte(a)googlemail.com&gt; * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -54,14 +54,16 @@ int virAuthGetConfigFilePath(virConnectPtr conn, return 0; } - for (i = 0 ; i < conn->uri->paramsCount ; i++) { - if (STREQ_NULLABLE(conn->uri->params[i].name, "authfile") && - conn->uri->params[i].value) { - VIR_DEBUG("Using path from URI '%s'", - conn->uri->params[i].value); - if (!(*path = strdup(conn->uri->params[i].value))) - goto no_memory; - return 0; + if (conn && conn->uri) { + for (i = 0 ; i < conn->uri->paramsCount ; i++) { + if (STREQ_NULLABLE(conn->uri->params[i].name, "authfile") && + conn->uri->params[i].value) { + VIR_DEBUG("Using path from URI '%s'", + conn->uri->params[i].value); + if (!(*path = strdup(conn->uri->params[i].value))) + goto no_memory; + return 0; + } } } -- 1.7.8.6
