The following PCRs are extended by shim:
PCR4:
- the Authenticode hash of the binary being loaded will be extended into
PCR4 before SB verification.
- the hash of any binary for which Verify is called through the shim_lock
protocol
PCR7:
- Any certificate in one of our certificate databases that matches a binary
we try to load will be extended into PCR7. That includes:
- DBX - the system blacklist, logged as "dbx"
- MokListX - the Mok blacklist, logged as "MokListX"
- vendor_dbx - shim's built-in vendor blacklist, logged as "dbx"
- DB - the system whitelist, logged as "db"
- MokList the Mok whitelist, logged as "MokList"
- vendor_cert - shim's built-in vendor whitelist, logged as "Shim"
- shim_cert - shim's build-time generated whitelist, logged as "Shim"
- MokSBState will be extended into PCR7 if it is set, logged as
"MokSBState".
PCR8:
- If you're using the grub2 TPM patchset we cary in Fedora, the kernel command
line and all grub commands (including all of grub.cfg that gets run) are
measured into PCR8.
PCR9:
- If you're using the grub2 TPM patchset we cary in Fedora, the kernel,
initramfs, and any multiboot modules loaded are measured into PCR9.
PCR14:
- MokList, MokListX, and MokSBState will be extended into PCR14 if they are
set.
