Extract with docker broken on master branch

[Flo354]

Hello,

The docker image doesn't work with the "-e" argument. It is working perfectly with tag "version-2.3.4"

<> docker run -it --rm -v "$(pwd):/home/appuser" refirmlabs/binwalk -e "file.bin"
[2024-10-19T13:43:56Z ERROR binwalk::binwalk] Failed to create symlink /home/appuser/extractions/file.bin -> /home/appuser/file.bin: Permission denied (os error 13)

From the permission denied error, it looks like a file permission problem; specifically, the user ID in the docker container (1337 by default) does not have write access to your $PWD.

You can check this by making $PWD /tmp, which is writable by everyone, and running the same command:

cp file.bin /tmp/file.bin
cd /tmp
sudo docker run -it --rm -v "$(pwd):/home/appuser" refirmlabs/binwalk -e "file.bin"

You could also instruct docker to use the root user instead, with the -u 0 argument:

sudo docker run -it -u 0 --rm -v "$(pwd):/home/appuser" refirmlabs/binwalk -e "file.bin"

Adjacent issue, solved by sudo su - on mac, and then running:

# docker run -it -u 0 --rm -v "$(pwd):/home/appuser" refirmlabs/binwalk:version-2.3.4 --run-as=root -Me "BIOS.BIN"
