The root node is supposed to have an empty name, but at present this is not checked. The behaviour of such a tree is not well defined. Most software rightly assumes that the root node is at offset 0 and does not check the name. This oddity was discovered as part of a security investigation into U-Boot verified boot. Add a check for this to fdt_check_full().
