Hi Mimi, Ignaz,
Mimi, could you please have a second look on this [4] patchset? We've had a
discussion about second patch [5], I can drop it if you don't like it, but
that's not a main concern about this test. More important is whether the
testcase looks valid for you. It's about overlayfs broken in IMA+EVM,
which is currently broken on mainline.
There is different reproducer (C code) for a slightly different scenario,
but I'm not going to port it before this got merged.
Ignaz, could you please test this patchset? Could you, please, share your setup?
ima_policy=appraise_tcb kernel parameter and loading IMA and EVM keys over
dracut-ima scripts? (IMA appraisal and EVM using digital signatures? I guess
using hashes for IMA appraisal would work as well).
Kind regards,
Petr
