+Subject: [PATCH 1/1] Free resources if certificate cannot be found
+
+In find_certificate_by_callback, function return -1 directly without
+free resource if node is null, that will lead to nss shut down failed.
+
+The error message as below:
+could not shut down NSS: NSS could not shutdown. Objects are still in use.
+
+To fix this issue, free all resources before function return -1.
