+Subject: [PATCH] Do not keep stale records by default
+
+By default set max-stale-ttl to 0, unless stale-answer-enable yes. This
+were enabled by mistake when backporting fix for CVE-2023-2828. It
+causes increased cache usage on servers not wanting to serve stale
+records. Fix that by setting smart defaults based on stale answers
+enabled with possible manual tuning.
