O_PATH ignores the O_CREAT flag so it's the same as just passing O_PATH. This is the case for all flags not in O_PATH_FLAGS (so only O_DIRECTORY, O_NOFOLLOW, O_CLOEXEC have an effect on O_PATH). With openat2, passing any other flag with O_PATH returns -EINVAL. -- Aleksa Sarai Senior Software Engineer (Containers) SUSE Linux GmbH <https://www.cyphar.com/>
