+5584. [bug] Rollback setting IP_DONTFRAG option on the UDP sockets.
+ [GL #2487]
+
5583. [func] Changes to DoH configuration syntax:
- When "http" is specified in "listen-on" or
"listen-on-v6" statements, "tls" must also now
list in ``named.conf``, the wrong size was passed to ``isc_mem_put()``,
which resulted in the returned memory being put on the wrong freed
list. This has been fixed. [GL #2460]
+
+- If an outgoing packet would exceed max-udp-size, it would be dropped instead
+ of sending a proper response back. Rollback setting the IP_DONTFRAG on the
+ UDP sockets that we enabled during the DNS Flag Day 2020 to fix this issue.
