### testing chroot jail functionality
### it requires setting up shared libraries in general!
### useful tools for setting up jail are ldd, lsof, "strace -f"

ldd tests/hello # what is needed in jail? lists two things in /lib64

mkdir chrootjail

cp tests/hello chrootjail

./safeexec --chroot_dir chrootjail --exec hello # execve error, caused by missing libs

mkdir chrootjail/lib64

cp /lib64/{ld-linux-x86-64.so.2,libc.so.6} chrootjail/lib64

./safeexec --chroot_dir chrootjail --exec hello # "Hello World" should show!

rm -rf chrootjail
