Thank you for more fully integrating the EVM portable signatures into IMA.
" [PATCH 08/11] ima: Allow imasig requirement to be satisfied by EVM portable signatures" equates an IMA signature to having a portable and immutable EVM signature. That is true in terms of signature verification, but from an attestation perspective the "ima-sig" template will not contain a signature. If not the EVM signature, then at least some other indication should be included in the measurement list.
Are you planning on posting the associated IMA/EVM regression tests?
