SubjectRe: [PATCH v5 03/21] evm: re-release
Quoting Mimi Zohar (
> +extern int evm_hmac_size;
> +int evm_hmac_size = SHA1_DIGEST_SIZE;

I think I object to having both MAX_DIGEST_SIZE and evm_hmac_size, both
of which are set to SHA1_DIGEST_SIZE throughout this patchset. Especially
because of the comment I was about to make on patch 4/21, where you
then prepend the hmac with a 'type' byte, and start passing around
MAX_DIGEST_SIZE+1 and evm_hmac_size+1.

Even if you're going to be using those differently in a later patchset,
let's focus on this set for now and keep things simpler. One constant
for the hmac size, and then please define a new one (in patch 4) for
the annotated digest size. I can't think think of a good name. Which
suggests that perhaps you should define a nicely typed struct to contain
the header+hmac...

I see no other problems, so presuming that these are nicely addressed
I expect to happily ack.
