Hey!
At the moment, I'm working on starting sio2jail on my server and I have some difficulties.
When I used sudo make check command, I can see the following messages:
LastTest.log

Rather, I'm wondering what intercepted forbidden syscall might be - before using sysctl -w kernel.perf_event_paranoid=-1, I observed another type of error - with perf events and forbidden access to them:
System error occured: perf event open failed: Permission denied: error 13: Permission denied
