Landlock Scoped Control

The “scoped” operations restrict operations which interact with processes in higher-privileged Landlock domains.

The two operations that are available as of LandlockAbiVersion V5 are:

• LANDLOCK_SCOPE_ABSTRACT_UNIX_SOCKET: Restrict the use of abstract UNIX Domain Sockets.
• LANDLOCK_SCOPE_SIGNAL: Restrict signaling of processes in higher-privileged Landlock domains.
