samples/bpf: extend test_cgrp2_attach2 test to use cgroup storage
The test_cgrp2_attach test covers bpf cgroup attachment code well,
so let's re-use it for testing allocation/releasing of cgroup storage.
The extension is pretty straightforward: the bpf program will use
the cgroup storage to save the number of transmitted bytes.
Expected output:
$ ./test_cgrp2_attach2
Attached DROP prog. This ping in cgroup /foo should fail...
ping: sendmsg: Operation not permitted
Attached DROP prog. This ping in cgroup /foo/bar should fail...
ping: sendmsg: Operation not permitted
Attached PASS prog. This ping in cgroup /foo/bar should pass...
Detached PASS from /foo/bar while DROP is attached to /foo.
This ping in cgroup /foo/bar should fail...
ping: sendmsg: Operation not permitted
Attached PASS from /foo/bar and detached DROP from /foo.
This ping in cgroup /foo/bar should pass...
