KMS and tendermint can't talk to each other (secret connection) #90
Description
I tried using the KMS as a remote signer:
- on the kms side I set:
[validator.connection]
type = "tcp"
addr = "127.0.0.1"
port = 8080
secret_key_path = "tests/support/secret_connection.key"- on the tendermint side I used (after
tendermint init):
/tendermint node --priv_validator_laddr=127.0.0.1:8080 --proxy_app=kvstore
This causes:
18:14:49 [INFO] KMS node ID: rawed255191nqmq3sj94emmzmnrg5lk702332scc60d65fuzfu80wfd95rugmpsvm6af9
thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: DecodeError { description: "buffer underflow", stack: [] }', libcore/result.rs:1009:5
note: Run with `RUST_BACKTRACE=1` for a backtrace.
on the KMS side; and
I[12116-11-12|19:14:48.783] Starting TCPVal module=privval impl=TCPVal

or sometimes sth like:
E[12116-11-12|19:28:20.953] OnStart module=privval err="unmarshal to [32]uint8 failed after 1 bytes (insufficient bytes decoding []byte of length 125): 7D4FEACC6C3A4E86C4302D7CBE33C873A7A9B1A47133D406B886B20885EB3F26"
on the tendermint side.
Looks like an encoding/decoding problem. I'm debugging what is going on here, update the issue accordingly, and provide a fix.
