4a20a92f4f replaced 994. with alternative fix: 
994.   [func]          Treat non-authoritative responses to queries for type
                        NS as referrals even if the NS records are in the
                        answer section, because BIND 8 servers incorrectly
                        send them that way.  This is necessary for DNSSEC
                        validation of the NS records of a secure zone to
                        succeed when the parent is a BIND 8 server. [RT #1706]

attempt a secure proof using the NS records found as

                        along with associated glue rather than from parent
                        servers.  [RT #1706]

0d19c777ae Use a counter instead of a flag to indicate if the resolver is in the 
process of connecting.  There's a possibility that a connect might not
have sent a completion event when another one starts, and this could cause
bad things to happen since the query would only know about one connect.

d1cc210d20 RT #927 fix from Bob: 
759.   [bug]           The resolver didn't turn off "avoid fetches" mode
                        when restarting, possibly causing resolution
                        to fail when it should not.  This bug only affected
                        platforms which support both IPv4 and IPv6. [RT #927]

 758.   [bug]           The "avoid fetches" code did not treat negative
                        cache entries correctly, causing fetches that would
                        be useful to be avoided.  This bug only affected
                        platforms which support both IPv4 and IPv6. [RT #927]

36608f2052 When returning from validation, make sure to handle chaiing correctly. 2001-02-21 05:16:44 +00:00
Bob Halley
1e50dad10d When returning DNS_R_CNAME or DNS_R_DNAME as the result of an ANY or SIG 
query, the resolver failed to setup the return event's rdatasets, causing an
assertion failure in the query code.  [RT #881]

The fix includes the addition of the DNS_NAMEATTR_CHAINING attribute,
and the removal of the DNS_NAMEATTR_CNAME and DNS_NAMEATTR_DNAME attributes,
because they were not used anywhere in the current source.
