The services for MeasurementArgs out in the brain.proto. I see here two options:

  • option 1: we do not commit any code for the measurement args RPC service
  • option 2: we turn the comments from the proto into running code and we test Measurement Args

My suggestion is to go for option 1, since that allows this PR to be isolated to the upgrade. I believe we should add measurement args in the future, if we see it is really needed. It will not be hard to add an extra RPC service when we need it. At this point, it is noise.

He went with option one without dropping a comment. 10 points abstracted from Griffindor.

If the daemon does not provide Measurement Args, the CLI can't execute the attestation. I believe we should not accept grpc::NewVmResp that does not contain Args. This should be replaced with a NewVmResp that contains an error with the message "SNP Node did not provide measurement args"

Also, this means the contract is broken so we need to discuss the cases.
