Title:
TPM event log does not contain events measured after ExitBootServices
Status in linux package in Ubuntu:
Confirmed
Bug description:
The TPM event log (/sys/kernel/security/tpm0/binary_bios_measurements)
does not contain any events that are measured by UEFI after the
kernel's EFI Boot stub calls ExitBootServices().
This means that PCR values calculated from the event log will not
match the actual PCR values on the machine for PCR indices into which
these events are measured.
There are upstream patches to fix this in the mainline kernel tree:
