*** perf_fuzzer 0.32-rc0 *** by Vince Weaver
Linux version 4.20.0-rc5 x86_64
Processor: Intel 6/60/3
Stopping after 30000
Watchdog enabled with timeout 60s
Will auto-exit if signal storm detected
Seeding RNG from time 1543899043
To reproduce, try:
echo 1 > /proc/sys/kernel/nmi_watchdog
echo 0 > /proc/sys/kernel/perf_event_paranoid
echo 1000 > /proc/sys/kernel/perf_event_max_sample_rate
./perf_fuzzer -s 30000 -r 1543899043
Fuzzing the following syscalls: mmap perf_event_open close read write ioctl fork prctl poll
Also attempting the following: signal-handler-on-overflow busy-instruction-loop accessing-perf-proc-and-sys-files trashing-the-mmap-page
Pid=13475, sleeping 1s
