As explained in commit aff39be0ed97: Both functions, object_initialize() and object_property_add_child() increase the reference counter of the new object, so one of the references has to be dropped afterwards to get the reference counting right. Otherwise the child object will not be properly cleaned up when the parent gets destroyed. Thus let's use now object_initialize_child() instead to get the reference counting here right. This patch was generated using the following Coccinelle script (with a bit of manual fix-up for overly long lines): @use_object_initialize_child@ expression parent_obj; expression child_ptr; expression child_name; expression child_type; expression child_size; expression errp; @@ ( - object_initialize(child_ptr, child_size, child_type); + object_initialize_child(parent_obj, child_name, child_ptr, child_size, + child_type, &error_abort, NULL); ... when != parent_obj - object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), NULL); ... ?- object_unref(OBJECT(child_ptr)); | - object_initialize(child_ptr, child_size, child_type); + object_initialize_child(parent_obj, child_name, child_ptr, child_size, + child_type, errp, NULL); ... when != parent_obj - object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), errp); ... ?- object_unref(OBJECT(child_ptr)); ) @use_sysbus_init_child_obj@ expression parent_obj; expression dev; expression child_ptr; expression child_name; expression child_type; expression child_size; expression errp; @@ ( - object_initialize_child(parent_obj, child_name, child_ptr, child_size, - child_type, errp, NULL); + sysbus_init_child_obj(parent_obj, child_name, child_ptr, child_size, + child_type); ... - qdev_set_parent_bus(DEVICE(child_ptr), sysbus_get_default()); | - object_initialize_child(parent_obj, child_name, child_ptr, child_size, - child_type, errp, NULL); + sysbus_init_child_obj(parent_obj, child_name, child_ptr, child_size, + child_type); - dev = DEVICE(child_ptr); - qdev_set_parent_bus(dev, sysbus_get_default()); ) While the object_initialize() function doesn't take an 'Error *errp' argument, the object_initialize_child() does. Since this code is used when a machine is created (and is not yet running), we deliberately choose to use the &error_abort argument instead of ignoring errors if an object creation failed. This choice also matches when using sysbus_init_child_obj(), since its code is: void sysbus_init_child_obj(Object *parent, const char *childname, void *child, size_t childsize, const char *childtype) { object_initialize_child(parent, childname, child, childsize, childtype, &error_abort, NULL); qdev_set_parent_bus(DEVICE(child), sysbus_get_default()); } Suggested-by: Eduardo Habkost <ehabkost@redhat.com> Inspired-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: Joel Stanley <joel@jms.id.au> Message-Id: <20190507163416.24647-8-philmd@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
