Currently the userspace RV tool starts a monitor and waits for the user to press Ctrl-C (SIGINT) to terminate and stop the monitor. This doesn't account for a scenario where a user starts RV in background and simply kills it (SIGTERM unless the user specifies differently). E.g.: # rv mon wip & # kill % Would terminate RV without stopping the monitor and next RV executions won't start correctly. Register the signal handler used for SIGINT also to SIGTERM.

RV: Runtime Verification
Runtime Verification (RV) is a lightweight (yet rigorous) method that
complements classical exhaustive verification techniques (such as model
checking and theorem proving) with a more practical approach for
complex systems.
The rv tool is the interface for a collection of monitors that aim
analysing the logical and timing behavior of Linux.
Installing RV
RV depends on the following libraries and tools:
- libtracefs
- libtraceevent
It also depends on python3-docutils to compile man pages.
For development, we suggest the following steps for compiling rtla:
$ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git
$ cd libtraceevent/
$ make
$ sudo make install
$ cd ..
$ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git
$ cd libtracefs/
$ make
$ sudo make install
$ cd ..
$ cd $rv_src
$ make
$ sudo make install
For further information, please see rv manpage and the kernel documentation:
