8.2.3 emits IN additional address records for HS queries.
In doaddinfo() there is code like the following.
The "!match(dp, C_IN, T_A) &&" in the if conditional need to
be removed.
Mark
ns_req.c:doaddinfo()
if (ap->a_type == T_A &&
!match(dp, (int)ap->a_class, T_A) &&
!match(dp, C_IN, T_A) &&
!match(dp, (int)ap->a_class, T_AAAA) &&
!match(dp, C_IN, T_AAAA) &&
!match(dp, (int)ap->a_class, ns_t_a6) &&
!match(dp, C_IN, ns_t_a6)) {
continue;
}
needs to become
if (ap->a_type == T_A &&
!match(dp, (int)ap->a_class, T_A) &&
!match(dp, (int)ap->a_class, T_AAAA) &&
!match(dp, (int)ap->a_class, ns_t_a6)) {
continue;
}
This has already been done to later versions of BIND 8.
