event_log format #32

Open mythi opened 5 months ago

mythi commented 5 months ago

The API docs says:

event_log   
Array of integers <uint8> [ items <uint8 > ]

Log of all events that get extended to RTMRs (runtime-extendable measurement registers). RTMR event log is available through ACPI.

a naive interpretation suggests that this is about reading the CCEL table and adding a base64 encoded string of the TCG formatted file to the request. However, that errors with a bad request.

Looking at the client code here, I can see it's parsing the CCEL file to drop the TCG format to build a custom JSON. Is there a doc somewhere what's in event_log that is passed via the REST API?

@mythi, here is the JSON format for event log:

here is the JSON format for event log:

is this the format ITA accepts? Do you have the documentation what the different fields are about (e.g., tags)?

yes, this is the format ITA accepts. Here is the mapping from TCG_PCR_EVENT2 struct:

rtmr.index field maps to pcrIndex field
rtmr.bank field maps to digests.hashAlg field
rtmr_event.type_id maps to eventType value (e.g., 0x80000001)
rtmr_event.type_name maps to eventType label (e.g., EV_EFI_VARIABLE_DRIVER_CONFIG)
rtmr_event.measurement maps to digests.digest field
rtmr_event.tags maps to event data (e.g., SecureBoot)

We have updated Intel Trust Authority API docs to capture the format. Just checked it's not released yet, reopening the issue.
