179	  The default is changed so that only DNSKEY RR's are annotated with
180	  an comment show the Key Tag of the DNSKEY.
181	* Fixed the ldns resolver to not mark a nameserver unreachable when
182	  edns0 is tried unsuccessfully with size 4096 (no return packet came),
183	  but to still try TCP. A big UDP packet might have been corrupted by
184	  fragments dropping firewalls.
185	* Update of libdns.vim (thanks Miek Gieben)
186	* Added the ldnsx Python module to our contrib section, which adds even
187	  more pythonisticism to the usage of ldns with  Python. (Many thanks

189	  The ldnsx module is automatically installed when --with-pyldns is
190	  used with configuring, but may explicitly be excluded with the

217	  names (in stead of just the ones that contain glue only) and all
218	  occluded records on the delegation points (in stead of just the glue).
219	* Clarify the operation of ldns_dnssec_mark_glue and the usage of
220	  ldns_dnssec_node_next_nonglue functions in the documentation.
221	* Added function ldns_dnssec_mark_and_get_glue as an real fast
222	  alternative for ldns_zone_glue_rr_list.
223	* Fix parse buffer overflow for max length domain names.
224	* Fix Makefile for U in environment, since wrong U is more common than
225	  deansification necessity.
226

379	* Fix occasional NSEC bitmap bogus
380	* Fix rr comparing (was in reversed order since 1.6.0)
381	* bug278: fix parsing HINFO rdata (and other cases).
382	* Fix previous owner name: also pick up if owner name is @.
383	* RFC5702: enabled sha2 functions by default. This requires OpenSSL 0.9.8 or higher.
384      Reason for this default is the root to be signed with RSASHA256.
385	* Fix various LDNS RR parsing issues: IPSECKEY, WKS, NSAP, very long lines
386	* Fix: Make ldns_dname_is_subdomain case insensitive.
387	* Fix ldns-verify-zone so that address records at zone NS set are not considered glue
388		(Or glue records fall below delegation)
389    * Fix LOC RR altitude printing.
390	* Feature: Added period (e.g. '3m6d') support at explicit TTLs.
391    * Feature: DNSKEY rrset by default signed with minimal signatures
392		but -A option for ldns-signzone to sign it with all keys.
393		This makes the DNSKEY responses smaller for signed domains.
394
3951.6.1   2009-09-14
396	* --enable-gost : use the GOST algorithm (experimental).
397	* Added some missing options to drill manpage
398	* Some fixes to --without-ssl option
399	* Fixed quote parsing withing strings
400	* Bitmask fix in EDNS handling
401	* Fixed non-fqdn domain name completion for rdata field domain
402	  names of length 1
403	* Fixed chain validation with SHA256 DS records
404
4051.6.0
406	Additions:
407	* Addition of an ldns-config script which gives cflags and libs
408	  values, for use in configure scripts for applications that use
409	  use ldns. Can be disabled with ./configure --disable-ldns-config
410	* Added direct sha1, sha256, and sha512 support in ldns.
411	  With these functions, all NSEC3 functionality can still be
412	  used, even if ldns is built without OpenSSL. Thanks to OpenBSD,
413	  Steve Reid, and Aaron D. Gifford for the code.
414	* Added reading/writing support for the SPF Resource Record
415	* Base32 functions are now exported
416	Bugfixes:
417	* ldns_is_rrset did not go through the complete rrset, but
418	  only compared the first two records. Thanks to Olafur
419	  Gudmundsson for report and patch
420	* Fixed a small memory bug in ldns_rr_list_subtype_by_rdf(),
421	  thanks to Marius Rieder for finding an patching this.
422	* --without-ssl should now work. Make sure that examples/ and
423	  drill also get the --without-ssl flag on their configure, if
424	  this is used.
425	* Some malloc() return value checks have been added
426	* NSEC3 creation has been improved wrt to empty nonterminals,
427	  and opt-out.
428	* Fixed a bug in the parser when reading large NSEC3 salt
429	  values.
430	* Made the allowed length for domain names on wire
431	  and presentation format the same.
432	Example tools:
433	* ldns-key2ds can now also generate DS records for keys without
434	  the SEP flag
435	* ldns-signzone now equalizes the TTL of the DNSKEY RRset (to
436	  the first non-default DNSKEY TTL value it sees)
437
4381.5.1
439	Example tools:
440	* ldns-signzone was broken in 1.5.0 for multiple keys, this
441	  has been repaired
442
443	Build system:
444	* Removed a small erroneous output warning in
445	  examples/configure and drill/configure
446
4471.5.0
448	Bug fixes:
449	* fixed a possible memory overflow in the RR parser
450	* build flag fix for Sun Studio
451	* fixed a building race condition in the copying of header
452	  files
453	* EDNS0 extended rcode; the correct assembled code number
454	  is now printed (still in the EDNS0 field, though)
455	* ldns_pkt_rr no longer leaks memory (in fact, it no longer
456	  copies anything all)
457
458	API addition:
459	* ldns_key now has support for 'external' data, in which
460	  case the OpenSSL EVP structures are not used;
461	  ldns_key_set_external_key() and ldns_key_external_key()
462	* added ldns_key_get_file_base_name() which creates a
463	  'default' filename base string for key storage, of the
464	  form "K<zone>+<algorithm>+<keytag>"
465	* the ldns_dnssec_* family of structures now have deep_free()
466	  functions, which also free the ldns_rr's contained in them
467	* there is now an ldns_match_wildcard() function, which checks
468	  whether a domain name matches a wildcard name
469	* ldns_sign_public has been split up; this resulted in the
470	  addition of ldns_create_empty_rrsig() and
471	  ldns_sign_public_buffer()
472
473	Examples:
474	* ldns-signzone can now automatically add DNSKEY records when
475	  using an OpenSSL engine, as it already did when using key
476	  files
477	* added new example tool: ldns-nsec3-hash
478	* ldns-dpa can now filter on specific query name and types
479	* ldnsd has fixes for the zone name, a fix for the return

481	  (Thanks to Colm MacCárthaigh for the patch)
482	* Fixed memory leaks in ldnsd
483
484
485

487	Bug fixes:
488	* fixed a build issue where ldns lib existence was done too early
489	* removed unnecessary check for pcap.h
490	* NSEC3 optout flag now correctly printed in string output
491	* inttypes.h moved to configured inclusion
492	* fixed NSEC3 type bitmaps for empty nonterminals and unsigned
493	  delegations
494
495	API addition:
496	* for that last fix, we added a new function
497	  ldns_dname_add_from() that can clone parts of a dname
498
4991.4.0
500	Bug fixes:
501	* sig chase return code fix (patch from Rafael Justo, bug id 189)
502	* rdata.c memory leaks on error and allocation checks fixed (patch

514	  Sury, bug 213)
515	* Fixed a small fallback problem in axfr client code
516
517	API CHANGES:
518	* added 2str convenience functions:
519		- ldns_rr_type2str
520		- ldns_rr_class2str
521		- ldns_rr_type2buffer_str
522		- ldns_rr_class2buffer_str
523	* buffer2str() is now called ldns_buffer2str
524	* base32 and base64 function names are now also prepended with ldns_
525	* ldns_rr_new_frm_str() now returns an error on missing RDATA fields.
526	  Since you cannot read QUESTION section RRs with this anymore,
527	  there is now a function called ldns_rr_new_question_frm_str()
528
529	LIBRARY FEATURES:
530	* DS RRs string representation now add bubblebabble in a comment
531	  (patch from Jakob Schlyter)
532	* DLV RR type added
533	* TCP fallback system has been improved
534	* HMAC-SHA256 TSIG support has been added.
535	* TTLS are now correcly set in NSEC(3) records when signing zones
536
537	EXAMPLE TOOLS:
538	* New example: ldns-revoke to revoke DNSKEYs according to RFC5011
539	* ldns-testpkts has been fixed and updated
540	* ldns-signzone now has the option to not add the DNSKEY
541	* ldns-signzone now has an (full zone only) opt-out option for
542	                NSEC3
543	* ldns-keygen can create HMAC-SHA1 and HMAC-SHA256 symmetric keys
544	* ldns-walk output has been fixed
545	* ldns-compare-zones has been fixed, and now has an option
546	  to show all differences (-a)
547	* ldns-read-zone now has an option to print DNSSEC records only
548
5491.3
550	Base library:
551
552	* Added a new family of functions based around ldns_dnssec_zone,
553	which is a new structure that keeps a zone sorted through an
554	rbtree and links signatures and NSEC(3) records directly to their
555	RRset. These functions all start with ldns_dnssec_
556
557	* ldns_zone_sign and ldns_zone_sign_nsec3 are now deprecated, but
558	have been changed to internally use the new
559	ldns_dnssec_zone_sign(_nsec3)
560
561	* Moved some ldns_buffer functions inline, so a clean rebuild of
562	applications relying on those is needed (otherwise you'll get
563	linker errors)
564	* ldns_dname_label now returns one extra (zero)
565	byte, so it can be seen as an fqdn.
566	* NSEC3 type code update for signing algorithms.
567	* DSA key generation of DNSKEY RRs fixed (one byte too small).
568
569	* Added support for RSA/SHA256 and RSA/SHA512, as specified in
570	draft-ietf-dnsext-dnssec-rsasha256-04. The typecodes are not
571	final, and this feature is not enabled by default. It can be
572	enabled at compilation time with the flag --with-sha2
573
574	* Added 2wire_canonical family of functions that lowercase dnames
575	in rdata fields in resource records of the types in the list in
576	rfc3597
577
578	* Added base32 conversion functions.
579
580	* Fixed DSA RRSIG conversion when calling OpenSSL
581
582	Drill:
583
584	* Chase output is completely different, it shows, in ascii, the
585	relations in the trust hierarchy.
586
587	Examples:
588	* Added ldns-verify-zone, that can verify the internal DNSSEC records
589	of a signed BIND-style zone file
590
591	* ldns-keygen now takes an -a argument specifying the algorithm,
592	instead of -R or -D. -a list show a list of supported algorithms
593
594	* ldns-keygen now defaults to the exponent RSA_F4 instead of RSA_3
595	for RSA key generation
596
597	* ldns-signzone now has support for HSMs
598	* ldns-signzone uses the new ldns_dnssec_ structures and functions
599	which improves its speed, and output; RRSIGS are now placed
600	directly after their RRset, NSEC(3) records directly after the
601	name they handle
602
603	Contrib:
604	* new contrib/ dir with user contributions
605	* added compilation script for solaris (thanks to Jakob Schlyter)
606
60728 Nov 2007 1.2.2:
608	* Added support for HMAC-MD5 keys in generator
609	* Added a new example tool (written by Ondrej Sury): ldns-compare-zones
610	* ldns-keygen now checks key sizes for rfc conformancy
611	* ldns-signzone outputs SSL error if present
612	* Fixed manpages (thanks to Ondrej Sury)
613	* Fixed Makefile for -j <x>
614	* Fixed a $ORIGIN error when reading zones
615	* Fixed another off-by-one error
616
61703 Oct 2007 1.2.1:
618	* Fixed an offset error in rr comparison
619	* Fixed ldns-read-zone exit code
620	* Added check for availability of SHA256 hashing algorithm
621	* Fixed ldns-key2ds -2 argument
622	* Fixed $ORIGIN bug in .key files
623	* Output algorithms as an integer instead of their mnemonic
624	* Fixed a memory leak in dnssec code when SHA256 is not available
625	* Updated fedora .spec file
626
62711 Apr 2007 1.2.0:
628	* canonicalization of rdata in DNSSEC functions now adheres to the
629	  rr type list in rfc3597, not rfc4035, which will be updated
630	  (see http://www.ops.ietf.org/lists/namedroppers/namedroppers.2007/msg00183.html)
631	* ldns-walk now support dnames with maximum label length
632	* ldnsd now takes an extra argument containing the address to listen on
633	* signing no longer signs every rrset with KSK's, but only the DNSKEY rrset
634	* ported to Solaris 10
635	* added ldns_send_buffer() function
636	* added ldns-testpkts fake packet server
637	* added ldns-notify to send NOTIFY packets
638	* ldns-dpa can now accurately calculate the number of matches per
639	  second
640	* libtool is now used for compilation too (still gcc, but not directly)
641	* Bugfixes:
642		- TSIG signing buffer size
643		- resolv.conf reading (comments)
644		- dname comparison off by one error
645		- typo in keyfetchers output file name fixed (a . too much)
646		- fixed zone file parser when comments contain ( or )
647		- fixed LOC RR type
648		- fixed CERT RR type
649
650	Drill:
651	* drill prints error on failed axfr.
652	* drill now accepts mangled packets with -f
653	* old -c option (use tcp) changed to -t
654	* -c option to specify alternative resolv.conf file added
655	* feedback of signature chase improved
656	* chaser now stops at root when no trusted keys are found
657	  instead of looping forever trying to find the DS for .
658	* Fixed bugs:
659		- wildcard on multiple labels signature verification
660		- error in -f packet writing for malformed packets
661		- made KSK check more resilient
662
6637 Jul 2006: 1.1.0: ldns-team
664	* Added tutorials and an introduction to the documentation
665	* Added include/ and lib/ dirs so that you can compile against ldns
666	  without installing ldns on your system
667	* Makefile updates
668	* Starting usage of assert throughout the library to catch illegal calls
669	* Solaris 9 testing was carried out. Ldns now compiles on that
670	  platform; some gnuism were identified and fixed.
671	* The ldns_zone structure was stress tested. The current setup
672	 (ie. just a list of rrs) can scale to zone file in order of
673	  megabytes. Sorting such zone is still difficult.
674	* Reading multiline b64 encoded rdata works.
675	* OpenSSL was made optional, configure --without-ssl.
676	  Ofcourse all dnssec/tsig related functions are disabled
677	* Building of examples and drill now happens with the same
678	  defines as the building of ldns itself.
679	* Preliminary sha-256 support was added. Currently is your
680	  OpenSSL supports it, it is supported in the DS creation.
681	* ldns_resolver_search was implemented
682	* Fixed a lot of bugs
683
684	Drill:
685	* -r was killed in favor of -o <header bit mnemonic> which
686	  allows for a header bits setting (and maybe more in the
687	  future)
688	* DNSSEC is never automaticaly set, even when you query
689	  for DNSKEY/RRSIG or DS.
690	* Implement a crude RTT check, it now distinguishes between
691	  reachable and unreachable.
692	* A form of secure tracing was added
693	* Secure Chasing has been improved
694	* -x does a reverse lookup for the given IP address
695
696	Examples:
697	* ldns-dpa was added to the examples - this is the Dns Packet
698	  Analyzer tool.
699	* ldnsd - as very, very simple nameserver impl.
700	* ldns-zsplit - split zones for parrallel signing
701	* ldns-zcat - cat split zones back together
702	* ldns-keyfetcher - Fetches DNSKEY records with a few (non-strong,
703	  non-DNSSEC) anti-spoofing techniques.
704	* ldns-walk - 'Walks' a DNSSEC signed zone
705	* Added an all-static target to the makefile so you can use examples
706	  without installing the library
707	* When building in the source tree or in a direct subdirectory of
708	  the build dir, configure does not need --with-ldns=../ anymore
709
710	Code:
711	* All networking code was moved to net.c
712	* rdata.c: added asserts to the rdf set/get functions
713	* const keyword was added to pointer arguments that
714	  aren't changed
715
716	API:
717	Changed:
718	* renamed ldns/dns.h to ldns/ldns.h
719	* ldns_rr_new_frm_str() is extented with an extra variable which
720	  in common use may be NULL. This trickles through to:
721	  o ldns_rr_new_frm_fp
722	  o ldns_rr_new_frm_fp_l
723	  Which also get an extra variable
724	  Also the function has been changed to return a status message.
725	  The compiled RR is returned in the first argument.
726	* ldns_zone_new_frm_fp_l()  and ldns_zone_new_frm_fp() are
727	  changed to return a status msg.
728	* ldns_key_new_frm_fp is changed to return ldns_status and
729	  the actual key list in the first argument
730	* ldns_rdata_new_frm_fp[_l]() are changed to return a status.
731	  the rdf is return in the first argument
732	* ldns_resolver_new_frm_fp: same treatment: return status and
733	  the new resolver in the first argument
734	* ldns_pkt_query_new_frm_str(): same: return status and the
735	  packet in the first arg
736	* tsig.h: internal used functions are now static:
737	  ldns_digest_name and ldns_tsig_mac_new
738	* ldns_key_rr2ds has an extra argument to specify the hash to
739	  use.
740	* ldns_pkt_rcode() is renamed to ldns_pkt_get_rcode, ldns_pkt_rcode
741	  is now the rcode type, like ldns_pkt_opcode
742	New:
743	* ldns_resolver_searchlist_count: return the searchlist counter
744	* ldns_zone_sort: Sort a zone
745	* ldns_bgsend(): background send, returns a socket.
746	* ldns_pkt_empty(): check is a packet is empty
747	* ldns_rr_list_pop_rr_list(): pop multiple rr's from another rr_list
748	* ldns_rr_list_push_rr_list(): push multiple rr's to an rr_list
749	* ldns_rr_list_compare(): compare 2 ldns_rr_lists
750	* ldns_pkt_push_rr_list: rr_list equiv for rr
751	* ldns_pkt_safe_push_rr_list: rr_list equiv for rr
752	Removed:
753	* ldns_resolver_bgsend(): was not used in 1.0.0 and is not used now
754	* ldns_udp_server_connect(): was faulty and isn't really part of
755	  the core ldns idea any how.
756	* ldns_rr_list_insert_rr(): obsoleted, because not used.
757	* char *_when was removed from the ldns_pkt structure
758
75918 Oct 2005: 1.0.0: ldns-team
760	* Commited a patch from Håkan Olsson
761	* Added UPDATE support (Jakob Schlyter and Håkan Olsson)
762	* License change: ldns is now BSD licensed
763	* ldns now depends on SSL
764	* Networking code cleanup, added (some) server udp/tcp support
765	* A zone type is introduced. Currently this is a list
766	  of RRs, so it will not scale well.
767	* [beta] Zonefile parsing was added
768	* [tools] Drill was added to ldns - see drill/
769	* [tools] experimental signer was added
770	* [building] better check for ssl

773	* [building] A lot of cleanup in the build scripts (thanks to Jakob Schlyter
774	and Paul Wouters)
775
77628 Jul 2005: 0.70: ldns-team
777	* [func] ldns_pkt_get_section now returns copies from the rrlists
778	  in the packet. This can be freed by the user program
779	* [code] added ldns_ prefixes to function from util.h
780	* [inst] removed documentation from default make install
781	* Usual fixes in documentation and code
782

785	not in 0.65
786	* dnssec_cd bit function was added
787	* Zone infrastructure was added
788	* Usual fixes in documentation and code

798	* keygen.c added as an example for DNSSEC programming
799
80023 May 2005: 0.60: ldns-team
801	* Removed config.h from the header installed files
802	  (you're not supposed to include that in a libary)
803	* Further tweaking
804	  - DNSSEC signing/verification works
805	  - Assorted bug fixes and tweaks (memory management)
806
807May 2005: 0.50: ldns-team
808	* First usable release
809	* Basic DNS functionality works
810	* DNSSEC validation works
811
