Hello Dieter, > I have a problem with the measurements of TrustedGRUB. The PCRs are extended, > but the measurements don't appear in the event log of the TPM in > /sys/kernel/security/tpm0. TrustedGRUB currently doesn't add the measurements in the measurement log. The main reason for this is that at the time when TrustedGRUB was developed, many BIOS didn't implement the necessary "TPM_HashLogExtendEvent" correctly or not even at all. This should in the meantime been fixed. Thanks for the reminder, I have now created a ticket for this: https://projects.sirrix.com/trac/trustedgrub/ticket/7 So the next release of TrustedGRUB will be enhanced and changed to support this BIOS call.
