6155. [bug] Treat ISC_R_INVALIDPROTO as a networking error
in the dispatch code to avoid retrying with the
same server. [GL #4005]<
libuv, treat it as a network failure, mark the server as broken and don't
try again. :gl:`#4005`
+- The :any:`max-transfer-time-in` and :any:`max-transfer-idle-in` options
+ were not implemented when the BIND 9 networking stack was refactored
+ in 9.16. The missing functionality has been re-implemented and
+ incoming zone transfers now time out properly when not progressing.
