Using the TLS context cache for server-side contexts could reduce the number of contexts to initialise in the configurations when e.g. the same 'tls' entry is used in multiple 'listen-on' statements for the same DNS transport, binding to multiple IP addresses. In such a case, only one TLS context will be created, instead of a context per IP address, which could reduce the initialisation time, as initialising even a non-ephemeral TLS context introduces some delay, which can be *visually* noticeable by log activity. Also, this change lays down a foundation for Mutual TLS (when the server validates a client certificate, additionally to a client validating the server), as the TLS context cache can be extended to store additional data required for validation (like intermediates CA chain). Additionally to the above, the change ensures that the contexts are not being changed after initialisation, as such a practice is frowned upon. Previously we would set the supported ALPN tags within isc_nm_listenhttp() and isc_nm_listentlsdns(). We do not do that for client-side contexts, so that appears to be an overlook. Now we set the supported ALPN tags right after server-side contexts creation, similarly how we do for client-side ones. |
