Comments for Lab 1: Dockerfile

Seems good! Few notes: AFL testcases are in different location than normally: /usr/local/share/afl/testcases/

Also, core_pattern property follows configuration on host system as kernel is shared in Linux systems. This requires running following command as root on host side to disable notifications of core dumps

echo core >/proc/sys/kernel/core_pattern

Also, depending on the type of CPU frequency scaling of host system, it might be required to be adjusted on host system, as AFL suggests:

Whoops, your system uses on-demand CPU frequency scaling, adjusted
    between 390 and 4101 MHz. Unfortunately, the scaling algorithm in the
    kernel is imperfect and can miss the short-lived processes spawned by
    afl-fuzz. To keep things moving, run these commands as root:

    cd /sys/devices/system/cpu
    echo performance | tee cpu*/cpufreq/scaling_governor

    You can later go back to the original state by replacing 'performance'
    with 'ondemand' or 'powersave'. If you don't want to change the settings,
    set AFL_SKIP_CPUFREQ to make afl-fuzz skip this check - but expect some
    performance drop.

There might be some more depending on the host system.

We could possibly publish Docker images in OUSPG:s package registry: https://github.com/orgs/ouspg/packages

Yes, I was planning to set up Ci for these to build for aarch64 and amd64 to help people who can't run the VMs
