util: make sure fd refers to regular file or directory when applying file attributes

System Internals / systemd - Lennart Poettering [poettering.net] - 22 April 2015 06:27 UTC

Before invoking file system ioctls we need to make sure that the specified fd actually refers to a file system object, and not a device node or similar. Otherwise we might by accident invoke unrelated device driver ioctls. For example, DRM ioctls use the same ioctl numbers as the
various file system ioctls.
