When starting a validator, the node initially joins gossip with shred_verison = 0, until it adopts the entrypoint's shred-version: https://github.com/solana-labs/solana/blob/9b182f408/validator/src/main.rs#L417 Depending on the load on the entrypoint, this adopting entrypoint shred-version through gossip sometimes becomes very slow, and causes several problems in gossip because we have to partially support shred_version == 0 which is a source of leaking crds values from one cluster to another. e.g. see https://github.com/solana-labs/solana/pull/17899 and the other linked issues there. In order to remove shred_version == 0 from gossip, this commit adds shred-version to ip-echo-server response. Once the entrypoints are updated, on validator start-up, if --expected_shred_version is not specified we will obtain shred-version from the entrypoint using ip-echo-server. |
