Hi all,

I wonder what to do with this patch "ima: skip verifying TPM 2.0 PCR values" [1].
Is it a correct way to differentiate between TPM 1.2 and TPM 2.0?
Or something else should be applied?

How is the work on TPM 2.0 Linux sysfs interface?
But even it's done in near future, we'd still need some way for older kernels.

Kind regards,
Petr
