Libnl ops that support updating objects may modify the object, even if we haven't handled the notification yet, causing older stored notifications to use an object "from the future". Avoid this by cloning the new object. Both nl_object_clone() and nl_object_put() are NULL-safe, so we don't need to do any nullptr checks. Signed-off-by: Jonas Gorski <[email protected]>

Depends on bisdn/meta-bisdn-linux#215, else it will crash with bridges or bonds |
