Sample reactor that panics the system when an exception is found. This is useful both to capture a vmcore, or to fail-safe a critical system.

Enable the kernel runtime verification infrastructure. RV is a
|
|
lightweight (yet rigorous) method that complements classical
|
|
exhaustive verification techniques (such as model checking and
|
|
theorem proving). RV works by analyzing the trace of the system's
|
|
actual execution, comparing it against a formal specification of
|
|
the system behavior.

Enables the online runtime verification reactors. A runtime
|
|
monitor can cause a reaction to the detection of an exception
|
|
on the model's execution. By default, the monitors have
|
|
tracing reactions, printing the monitor output via tracepoints,
|
|
but other reactions can be added (on-demand) via this interface.
