65a66336a6 redid configuration locking using isc_task_beginexclusive() 
and isc_task_endexclusive() instead of a multitude of separate
configuration rwlocks

3d76b54512 Don't create a timer for every incoming query - only create it for updates, 
notifies, and recursive queries.

75534b6392 optimization: when deciding whether to do v6 syntheis, check the query type 
before the ACL because it's usually faster that way

d29da750d2 statistics counting was slowing down the server. Make client.c:count_query() 
inline and remove dns_stats_ncounters(), which just returned the public
constant DNS_STATS_NCOUNTERS.

634784cb66 701. [func] Root hints are now fully optional. Class IN 
views use compiled-in hints by default, as
                        before.  Non-IN views with no root hints now
                        provide authoritative service but not recursion.
                        A warning is logged if a view has neither root
                        hints nor authoritative data for the root. [RT #696]

576f85e5fd 673. [func] The server can now convert RFC1886-style recursive 
lookup requests into RFC2874-style lookups, when
                        enabled using the new option "allow-v6-synthesis".

b23f160d5b simplified handling of the query type, removing the final 
vestiges of support for multiple queries per packet, in preparation
for AAAA synthesis code which needs to know the query type earlier
than it was previously available

ec772e873b 651. [func] The AD bit in responses now has the meaning 
specified in <draft-ietf-dnsext-ad-is-secure>.

6d5032f9a2 Micro-optimizations: 
- use the DNS_NAME_INIT macro in name.c
	- create dns_name_copy() and use it instead of dns_name_concatenate()
	  when doing a copy.

af5dc286ff 640. [bug] Memory leak in error path could cause 
"mpctx->allocated == 0" failure. [RT #584]

c8fc692fa1 618. [bug] Queries to a signed zone could sometimes cause

d3be9a9c6e 583. [func] "rndc querylog" will now toggle logging of 
queries, like "ndc querylog" in BIND 8.

86a4d80e06 565. [func] Log queries more like BIND 8: query logging is now 
done to category queries, level info. [RT #169]

ab13b279ae revert the change of 1.151->1.152 - it is more important to log 
queries sanely than to log them the same way BIND 8 did

7fd17f3f4d 565. [func] Log queries more like BIND 8. Query logging is done 
to category "general", module "query", debug level 1.

e9f6414d40 simplified query logging code by dropping support for EDNS1 
multiple queries and by using dns_rdata{type,class}_format();
include the class in query log messages

eb23b7b590 eliminated compiler warnings; 
renamed setup_sortlist() to ns_sortlist_setup() to conform
to naming conventions

50faa6daf7 refactored sortlist code to make it possible to sort addresses 
that are not part of an rdata, as required by lwresd

78d78f05d9 556. [func] The DNSSEC OK bit in the EDNS extended flags 
is now implemented.  Responses to queries without
                        this bit set will not contain any DNSSEC records.

a3a11c4f3f Add the ability (via rndc dump-statistics) to dump a file with counters of 
various results given to queries.  Enable the (previously disabled)
statistics-file config option.

c03bb27f06 532. [func] Implement DNS UPDATE pseudo records using 
DNS_RDATA_UPDATE flag.

 531.   [func]          Rdata really should be initalized before being
                        assigned to (dns_rdata_fromwire(), dns_rdata_fromtext(),
                        dns_rdata_clone(), dns_rdata_fromregion()),
                        check that it is.

55aed608cc Add counters of incoming queries, server-wide and by zone. There is 
currently no way to get these counts back *out* of the server, pending
a command channel.  A temporary channel should be built for these data
soon.

f6b2acd608 Minor change to make GNS changes easier, as well as a minor typo. 2000-10-11 18:00:08 +00:00
Michael Sawyer
dc570b92f6 Add support for proposed ZONE and VIEW opt attributes. These are currently 
hidden behind #ifdef's, since no OPT code number has yet to be assigned
by the IANA.  They are also not quite complete in all regards; VIEW
options are understood and ignored.  ZONE options are understood and
acted upon, though some of the error cases aren't quite right.

Remove doubled isc_mem_stats in dighost.c

Update todo list.

Change literal 255's to DNS_NAME_MAXWIRE in name.c

88cef4408a 493. [func] Return non-cachable (ttl = 0) NXDOMAIN responses 
for SOA queries.  This makes it easier to locate
                        the containing zone without polluting intermediate
                        caches.

337ca18384 475. [bug] query_getzonedb() sometimes returned a non-null version 
on failure.  This caused assertion failures when
                        generating query responses where names subject to
                        additional section processing pointed to a zone
                        to which access had been denied by means of the
                        allow-query option. [RT #336]
