This flag indicates the path should be opened if it's a regular file. This is useful to write secure programs that want to avoid being tricked into opening device nodes with special semantics while thinking they operate on regular files. This is a requested feature from the uapi-group[1]. A corresponding error code EFTYPE has been introduced. For example, if openat2 is called on path /dev/null with OPENAT2_REGULAR in the flag param, it will return -EFTYPE. EFTYPE is already used in BSD systems like FreeBSD, macOS. When used in combination with O_CREAT, either the regular file is created, or if the path already exists, it is opened if it's a regular file. Otherwise, -EFTYPE is returned. When OPENAT2_REGULAR is combined with O_DIRECTORY, -EINVAL is returned as it doesn't make sense to open a path that is both a directory and a regular file.
