docker mount failed when creating angrProjectBow

[jacky-wilson]

Hi,

When I tried to run "python test/test_bow_angr.py", I got the following error:

mount: /tmp/archr_mounts/ad53a3e1edbb4216b30219b3673052f70833dc42fd2576dda50f2f10d64982c0: special device /home/johnson/dockers/overlay2/7953906f2439673aefed891c9c8d16681e6de7a9a512a8701618cfb0a7c330ea/merged does not exist.

umount: /tmp/archr_mounts/ad53a3e1edbb4216b30219b3673052f70833dc42fd2576dda50f2f10d64982c0: not mounted.

By debugging the program line by line, I found that this problem is caused by the following line in docker_target.py/mount_local function

os.system(_super_mount_cmd + "mount -o bind %s %s" % (self._merged_path, self.local_path))

My os is ubuntu 16.04 and docker version is 18.03.0-ce.

Probably something to do with your docker configuration. The relevant error is the first line.

The following is the content in /etc/docker/daemon.json:

{
"iptables": false,
"ip-masq": false,
"storage-driver": "overlay2",
"graph": "/home/johnson/dockers"
}

Would you please help me figure out the problem, or just show me your configuration file?

[rhelmot]

Mine only has the storage driver line. If it doesn't work without the others I have no idea how to help you.

@rhelmot what's your docker version?

[rhelmot]

I installed via get.docker.io a few days ago. I can't tell you the exact version until I get back to my computer tomorrow.

Solved by deleting "graph": "/home/johnson/dockers". The problem is probably caused by file permissions of docker. Thanks @rhelmot.
