This subsystem has been a frequent source of security vulnerabilities affecting the Linux kernel; as a result, Google announced on June 14, 2023, that they would disable it in their environment as widely as possible. IPFire does not depend on the availability of io_uring. Therefore, disable this subsystem as well in order to preemptively cut attack surface.
