The deserialization of authenticatorGetAssertion requests using the hmac-secret extension as sent by e. g. python-fido2 currently fails. This patch adds some tests with the offending input.
The December 08, 2020 version of the Client to Authenticator Protocol (CTAP) specification added the pinUvAuthProtocol(0x04) field to the input data for the hmac-secret extension in the authenticatorGetAssertion command. This patch adds this new field to the HmacSecretInput struct to make it possible to parse requests using this new field. https://fidoalliance.org/specs/fido-v2.1-rd-20201208/fido-client-to-authenticator-protocol-v2.1-rd-20201208.html Fixes trussed-dev#1.
