Running CGC binaries with Driller

[tiwns]

Hello, I have been trying to run driller in a docker container and cannot seem to get it to work. The error I obtain -

shellphuzz -d 2 -w workdir/shellphuzz/ -C --length-extension 4 ./CADET_00001
[] Drilling...
[] Creating fuzzer...

Running 'echo 1 | sudo tee /proc/sys/kernel/sched_child_runs_first' tells me the file system is read_only.

Any advice would be much appreciated.

I believe you need to either run the container as privileged, or you can run it on the host.
