Each QUIC congestion algorithm is defined as a structure with callbacks in it. Every quic_conn has a member pointing to the configured algorithm, inherited from the bind-conf keyword or to the default CUBIC value. Convert all these definitions to const. This ensures that there never will be an accidental modification of a globally shared structure. This also requires to mark quic_cc_algo field in bind_conf and quic_cc as const.
