Therefore if +the client wants the DNSSEC RRs, the query can not be answered from +the cache. When DNSSEC validation is enabled, any query with the +do-bit set is never answered from the cache, unless the domain is +known not to be signed: the query is always forwarded. This ensures +that the DNSEC RRs are included. + +The same thing should be true when DNSSEC validation is not enabled, +but there's a bug in the logic. + +line 1666 of src/rfc1035.c looks like this + + if ((crecp->flags & (F_HOSTS | F_DHCP | F_CONFIG)) || !do_bit || !(crecp->flags & F_DNSSECOK)) + +{ ...answer from cache ... } + +So local stuff (hosts, DHCP, ) get answered. If the do_bit is not set +then the query is answered, and if the domain is known not to be +signed, the query is answered. + +Unfortunately, if DNSSEC validation is not turned on then the +F_DNSSECOK bit is not valid, and it's always zero, so the question +always gets answered from the cache, even when the do-bit is set. + +This code should look like that at line 1468, dealing with PTR queries + + if ((crecp->flags & (F_HOSTS | F_DHCP | F_CONFIG)) || + !do_bit || + (option_bool(OPT_DNSSEC_VALID) && !(crecp->flags & F_DNSSECOK))) + +where the F_DNSSECOK bit is only used when validation is enabled. + +Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk> +--- + CHANGELOG | 7 ++++++- + src/rfc1035.c | 6 ++++-- + 2 files changed, 10 insertions(+), 3 deletions(-) + +--- a/CHANGELOG ++++ b/CHANGELOG +@@ -33,7 +33,12 @@ version 2.80 + even if auth-sec-servers is not.
