This commit adds basic serial link and protocol support. None of the commands
from the docs/design.md document is implemented yet.
The following new packages have been added:
- seriallink containing the serial link handler including COBS decoding and
encoding
- protocol containing the protocol handler including msgpack unmarshalling
and marshaling
- health containing a rudimentary health check implementation
- messages containing command and response types and generated msgpack
marshaling code
A client simulation command has been added in cmd/clientsim.
README.md got instructions how to run the client simulator. The
docs/config.sample.yaml contains a new section for the serial connection
parameters.
- create new type hsm.Access to encapsulate HSM operations
- make setup options operate on hsm.Access instances
- adapt tests and cmd/signer to work with hsm.Access
