Hi all, I think I met a problem about cgroup devices. The following is my detailed operations: # cd /sys/fs/cgroup/devices/ # mkdir test # echo "c 1:3 rw" > test/devices.deny # cat test/devices.list a *:* rwm It seems my setting does not react in devices.list. But in another terminal, /dev/null is really limited to access. $ sudo cgexec -g devices:test dd if=/dev/zero of=/dev/null bs=1M count=128 dd: failed to open '/dev/null': Operation not permitted So, is this a bug of cgroup devices?
