Fail to build multiple targets in rootless docker

[qhjchc]

Hi,

I could not run multiple targets in rootless docker.

For example, if I run the following command with the captainrc ./tools/captain/run.sh ./tools/captain/captainrc

• captainrc

...
FUZZERS=(afl)
afl_TARGETS=(libpng sqlites)

It could build the first target successfully but fail to the following targets. The log in the following targets is as follows:

+ docker build -t magma/afl/sqlites --build-arg fuzzer_name=afl --build-arg target_name=sqlites --build-arg USER_ID=1000 --build-arg GROUP_ID=1000 --build-arg canaries=1 --build-arg isan=1 -f /home/xxx/magma/docker/Dockerfile /home/xxx/magma

error checking context: 'no permission to read from '/home/xxx/magma/workdir/cache/afl/libpng/libpng_read_fuzzer/0/findings/.cur_input''.

sqlites is a typo; it should be sqlite3. Is that the reason?

Sorry for my typo. It is the same when using sqlite3. (The above example is not directed copied from the log so I make a typo)

The following are the details. I use rootless docker and it failed to build a list of targets. (All docker containers and images are killed to avoid some unknown mistakes and then download the magma)

Then I run the following command with the captainrc file. ./tools/captain/run.sh ./tools/captain/captainrc

• captainrc

FUZZERS=(afl)
afl_TARGETS=(libpng libsndfile libtiff libxml2 lua openssl php poppler sqlite3)

It is a docker issue rather than this repo. Sorry for bothering you :)
