-Subject: [PATCH 12/14] DDF: validate metadata_update size before using it.
-
-process_update already checks update->len, for all but
-the 'magic', prepare_update doesn't at all.
-
-So add tests to prepare_update that we don't exceed the buffer.
-This will consequently protect process_update from looking
-for a 'magic' which isn't there.
