Re: [PATCH v4 2/6] configfs-tsm: Introduce a shared ABI for attestation reports

[Thomas Fossati]

Caveat: newbie here (just subscribed the linux-coco list) trying to
bridge the abstract language of IETF RATS with an actual
implementation of the architecture.

Could you clarify the semantics of @certs?

Are these what the IETF calls platform "endorsements" [1], [2]?
Or could a DICE report (which is a cert chain) fall into this bucket too?

If the former, maybe @endorsement_certs (or similar) would minimise ambiguity.
