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... ERROR | 2020-09-03 16:33:21,002 | fuzzer.fuzzer | AFL Warning: We probably want the fork() children to run first execute 'echo 1 | sudo tee /proc/sys/kernel/sched_child_runs_first'

Exception ignored in: <bound method Fuzzer.del of <fuzzer.fuzzer.Fuzzer object at 0x7f6062895e10>> Traceback (most recent call last): File "/home/angr/angr-dev/fuzzer/fuzzer/fuzzer.py", line 665, in del self.kill() File "/home/angr/angr-dev/fuzzer/fuzzer/fuzzer.py", line 266, in kill for p in self.procs: AttributeError: 'Fuzzer' object has no attribute 'procs'

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.
