I submit the patch again, according to patch submission convension. This patch enables to accept percent-encoded object names as forth argument of /selinux/create interface to avoid possible bugs when we give an object name including whitespace or multibutes. E.g) if and when a userspace object manager tries to create a new object named as "resolve.conf but fake", it shall give this name as the forth argument of the /selinux/create. But sscanf() logic in kernel space fetches only the part earlier than the first whitespace. In this case, selinux may unexpectedly answer a default security context configured to "resolve.conf", but it is bug. Although I could not test this patch on named TYPE_TRANSITION rules actually, But debug printk() message seems to me the logic works correctly. I assume the libselinux provides an interface to apply this logic transparently, so nothing shall not be changed from the viewpoint of application.
