Description of changes:
Currently s2n-quic emits the
on_server_name_informationevent after it receives and installs the 1-rtt keys (and does a bunch of validation). This means that its possible to abort the handshake if any of the validation fails and not emit the server_name event.This makes it difficult for servers to debug which clients(server_name) is experiencing failures.
This PR moves the
on_server_name_informationevent to right after the server_name is parsed which solves the issue above.Similarly this PR also emits the
application_protocoland the associated event earlier.Callout:
Testing:
Existing test which complete the handshake should still pass. There is an inline assert which confirms that
on_server_namehappens prior to 1-rtt keys.Is this a refactor change? If so, how have you proved that the intended behavior hasn't changed? -->
