What this PR does / why we need it:
This PR exposes a
gardensubcommand1 in pcr-oracle that takes efi variables that get measured into PCR7 as arguments. It then constructs EV_EFI_VARIABLE_DRIVER_CONFIG and EV_EFI_VARIABLE_AUTHORITY and computes their digests.This allows the construction of hypothetical future event logs and the precomputation of PCR registers in combination with tools like systemd-pcrlock.
Usage:
Which issue(s) this PR fixes:
n/a
Special notes for your reviewer:
The patched in C code may not be too elegant, but it works :)
