Hi

DSA-3904-1 (and the respective DLA) introduced a regression as
described in:

https://lists.isc.org/pipermail/bind-announce/2017-July/001054.html

"Problems may occur when transferring from another server if
TSIG is used *and* the AXFR or IXFR is more than two messages
in length *and* the master server does not sign every message.
NSD is an example of a popular DNS product that behaves in this
manner [note: NSD's behavior is in compliance with the requirements
of the RFC; it is BIND that has introduced a problem here.]"
