126 otherwise it is treated as insecure. The RSAMD5 algorithm is
127 deprecated (RFC6725). The MD5 hash is considered weak for some
128 purposes, if you want to sign your zone, then RSASHA256 is an

348 23 February 2012: Wouter
349 - Fix to squelch 'network unreachable' errors from tcp connect in
350 logs, high verbosity will show them.
352 16 February 2012: Wouter
353 - iter_hints is now thread-owned in module env, and thus threadsafe.
354 - Fix prefetch and sticky NS, now the prefetch works. It picks
355 nameservers that 'would be valid in the future', and if this makes
356 the NS timeout, it updates that NS by asking delegation from the
357 parent again. If child NS has longer TTL, that TTL does not get
358 refreshed from the lookup to the child nameserver.
360 15 February 2012: Wouter

386 implementation is experimental at this time and not recommended
387 for use on the public internet (the protocol numbers have not
388 been assigned). Needs recent ldns with --enable-ecdsa.
389 - fix memory leak in errorcase for DSA signatures.

403 closest encloser from yy for DS zz. while building chain of trust,
404 because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
405 for an NSEC3. Now it does not change rdata, and fixes TTL.
407 30 January 2012: Wouter
408 - Fix version-number in libtool to be version-info so it produces
409 libunbound.so.2 like it should.
411 26 January 2012: Wouter
412 - Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.

423 19 January 2012: Wouter
424 - Fix to write key files completely to a temporary file, and if that

429 - updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
431 17 January 2012: Wouter
432 - Fix bug where canonical_compare of RRSIG did not downcase the
433 signer-name. This is mostly harmless because RRSIGs do not have
434 to be sorted in canonical order, usually.
436 12 January 2012: Wouter
437 - bug#428: add ub_version() call to libunbound. API version increase,
438 with (binary) backwards compatibility for the previous version.
440 10 January 2012: Wouter
441 - Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
442 that would be permissible by the RFCs but it is not the TTL in the

445 - uninitialised variable in reprobe for rtt blocked domains fixed.
446 - lintfix and new flex output.

452 24 December 2011: Wouter
453 - Fix for memory leak (about 20 bytes when a tcp or udp send operation

516 - fix -flto detection on Lion for llvm-gcc.
518 31 October 2011: Wouter
519 - dns over ssl support, ssl-service-pem and ssl-service-key files
520 can be given and then TCP queries are serviced wrapped in SSL.
522 27 October 2011: Wouter
523 - lame-ttl and lame-size options no longer exist, it is integrated
524 with the host info. They are ignored (with verbose warning) if
525 encountered to keep the config file backwards compatible.
526 - fix iana-update for changing gzip compression of results.
527 - fix export-all-symbols on OSX.
529 26 October 2011: Wouter
530 - iana portlist updated.

537 server selection for choosing out of a (particular) list of bad
539 - Fix make_new_space function so that the incoming query is not
540 overwritten if a jostled out query causes a waiting query to be
541 resumed that then fails and sends an error message. (Thanks to
544 21 October 2011: Wouter
545 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
546 option enabled because of memory layout exe vs dll.
548 19 October 2011: Wouter
549 - fix unbound-anchor for broken strptime on OSX lion, detected
551 - Detect if GOST really works, openssl1.0 on OSX fails.

557 14 October 2011: Wouter
558 - Fix for out-of-memory condition in libunbound (thanks
561 13 October 2011: Wouter
562 - Fix --enable-allsymbols, it depended on link specifics of the
563 target platform, or fptr_wlist assertion failures could occur.
565 12 October 2011: Wouter
566 - updated contrib/unbound_munin_ to family=auto so that it works with
567 munin-node-configure automatically (if installed as
568 /usr/local/share/munin/plugins/unbound_munin_ ).
570 27 September 2011: Wouter
571 - unbound.exe -w windows option for start and stop service.
573 23 September 2011: Wouter

577 20 September 2011: Wouter
578 - Fix classification of NS set in answer section, where there is a
579 parent-child server, and the answer has the AA flag for dir.slb.com.
580 Thanks to Amanda Constant from Secure64.
582 16 September 2011: Wouter
583 - fix bug #408: accept patch from Steve Snyder that comments out
584 unused functions in lookup3.c.
585 - iana portlist updated.
586 - fix EDNS1480 change memleak and TCP fallback.
587 - fix various compiler warnings (reported by Paul Wouters).
588 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
589 fetch if sentcount > 3, stop query if sentcount > 16. Count is
590 reset when referral or CNAME happens. This makes unbound better
591 at managing large NS sets, they are explored when there is continued
592 interest (in the form of queries).
594 15 September 2011: Wouter
596 - trunk contains 1.4.14 in development.
597 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
599 12 September 2011: Wouter

605 - Fix operation in ipv6 only (do-ip4: no) mode.
607 6 September 2011: Wouter
608 - fedora specfile updated.

613 2 September 2011: Wouter
614 - iana portlist updated.
616 26 August 2011: Wouter
617 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
618 - Fix validation failures due to EDNS backoff retries, the retry
619 for fetch of data has want_dnssec because the iter_indicate_dnssec
620 function returns true when validation failure retry happens, and
621 then the serviced query code does not fallback to noEDNS, even if
622 the cache says it has this. This helps for DLV deployment when
623 the DNSSEC status is not known for sure before the lookup concludes.
625 24 August 2011: Wouter
626 - Applied patch from Karel Slany that fixes a memory leak in the
627 unbound python module, in string conversions.
629 22 August 2011: Wouter
630 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
631 Zhang and Luo Ce). Unbound responds with the RR types that are
632 available at the name for qtype ANY and validates those RR types.
633 It does not test for completeness (i.e. with NSEC or NSEC3 query),
634 and it does not follow the CNAME or DNAME to another name (with
635 even more data for the already large response).
636 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
637 - Documented the options that work with control set_option command.
638 - tcp-upstream yes/no option (works with set_option) for tunnels.
640 18 August 2011: Wouter
641 - fix autoconf call in makedist crosscompile to RC or snapshot.
643 17 August 2011: Wouter

683 - tag relase 1.4.11, trunk is 1.4.12 development.
684 - iana portlist updated.
685 - fix bug#395: id bits of other query may leak out under conditions
686 - fix replyaddr count wrong after jostled queries, which leads to
687 eventual starvation where the daemon has no replyaddrs left to use.
688 - fix comment about rndc port, that referred to the old port number.
689 - fix that the listening socket is not closed when too many remote
690 control connections are made at the same time.
691 - removed ldns-src tarball inside the unbound tarball.
694 - Changed -flto check to support clang compiler.
695 - tag 1.4.11rc3 created.
698 - tag 1.4.11rc1 created.

704 - log-queries: yesno option, default is no, prints querylog.
708 - Use -flto compiler flag for link time optimization, if supported.
709 - iana portlist updated.
712 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
715 - unbound-control has version number in the header,
716 UBCT[version]_space_ is the header sent by the client now.
717 - Unbound control port number is registered with IANA:
718 ub-dns-control 8953/tcp unbound dns nameserver control
719 This is the new default for the control-port config setting.
720 - statistics-interval prints the number of jostled queries to log.
723 - Fix Makefile for U in environment, since wrong U is more common than
724 deansification necessity.
725 - iana portlist updated.
726 - updated ldns tarball to 1.6.10rc2 snapshot of today.
729 - Fix assertion failure when unbound generates an empty error reply
730 in response to a query, CVE-2011-1922 VU#531342.
731 - This fix is in tag 1.4.10.
732 - defense in depth against the above bug, an error is printed to log
733 instead of an assertion failure.

745 12 April 2011: Wouter
746 - bug#378: Fix that configure checks for ldns_get_random presence.
749 - iana portlist updated.
750 - queries with CD flag set cause DNSSEC validation, but the answer is
751 not withheld if it is bogus. Thus, unbound will retry if it is bad
752 and curb the TTL if it is bad, thus protecting the cache for use by
753 downstream validators.
754 - val-override-date: -1 ignores dates entirely, for NTP usage.
756 29 March 2011: Wouter
757 - harden-below-nxdomain: changed so that it activates when the
758 cached nxdomain is dnssec secure. This avoids backwards
759 incompatibility because those old servers do not have dnssec.
761 24 March 2011: Wouter
762 - iana portlist updated.
766 17 March 2011: Wouter
767 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.

793 Please note usage of unbound-anchor root anchor is at your own risk
794 and under the terms of our LICENSE (see that file in the source).
796 11 February 2011: Wouter
797 - iana portlist updated.
798 - tpkg updated with common.sh for common functionality.
800 7 February 2011: Wouter

819 - add get and set option for harden-below-nxdomain feature.
820 - iana portlist updated.
822 14 January 2011: Wouter
823 - Fix so a changed NS RRset does not get moved name stuck on old
824 server, for type NS the TTL is not increased.
826 13 January 2011: Wouter
827 - Fix prefetch so it does not get stuck on old server for moved names.
829 12 January 2011: Wouter
830 - iana portlist updated.
832 11 January 2011: Wouter
833 - Fix insecure CNAME sequence marked as secure, reported by Bert
836 10 January 2011: Wouter
837 - faster lruhash get_mem routine.

840 - bug#346: remove ITAR scripts from contrib, the service is discontinued, use the root.
841 - iana portlist updated.
843 23 December 2010: Wouter
844 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
846 21 December 2010: Wouter
847 - algorithm compromise protection using the algorithms signalled in
848 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
849 and thus, if you have multiple algorithms in your trust-anchor-file
850 then it will now behave different than before. Also, 5011 rollover
851 for algorithms needs to be double-signature until the old algorithm
853 It is not an option, because I see no use to turn the security off.
854 - iana portlist updated.
856 17 December 2010: Wouter
857 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
858 - fix validation in this case: CNAME to nodata for co-hosted opt-in
859 NSEC3 insecure delegation, was bogus, fixed to be insecure.
861 16 December 2010: Wouter
862 - Fix our 'BDS' license (typo reported by Xavier Belanger).
864 10 December 2010: Wouter
865 - iana portlist updated.

876 - iana portlist updated.
878 18 November 2010: Wouter
879 - harden-below-nxdomain option, default off (because very old
880 software may be incompatible). We could enable it by default in
883 17 November 2010: Wouter
884 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
885 - make test output nicer.
887 15 November 2010: Wouter

889 - iana portlist updated.
890 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
892 9 November 2010: Wouter
893 - unbound-anchor compiles with openssl 0.9.7.
895 8 November 2010: Wouter

900 5 November 2010: Wouter
901 - do not synthesize a CNAME message from cache for qtype DS.
903 4 November 2010: Wouter
904 - Use central entropy to seed threads.
906 3 November 2010: Wouter
907 - Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
909 2 November 2010: Wouter
913 1 November 2010: Wouter
914 - GOST code enabled by default (RFC 5933).
916 27 October 2010: Wouter
917 - Fix uninit value in dump_infra print.
918 - Fix validation failure for parent and child on same server with an
919 insecure childzone and a CNAME from parent to child.
920 - Configure detects libev-4.00.
922 26 October 2010: Wouter
923 - dump_infra and flush_infra commands for unbound-control.
924 - no timeout backoff if meanwhile a query succeeded.
925 - Change of timeout code. No more lost and backoff in blockage.
926 At 12sec timeout (and at least 2x lost before) one probe per IP
927 is allowed only. At 120sec, the IP is blocked. After 15min, a
928 120sec entry has a single retry packet.
930 25 October 2010: Wouter
931 - Configure errors if ldns is not found.
933 22 October 2010: Wouter
934 - Windows 7 fix for the installer.
936 21 October 2010: Wouter
937 - Fix bug where fallback_tcp causes wrong roundtrip and edns
938 observation to be noted in cache. Fix bug where EDNSprobe halted
939 exponential backoff if EDNS status unknown.
940 - new unresponsive host method, exponentially increasing block backoff.
941 - iana portlist updated.
943 20 October 2010: Wouter
944 - interface automatic works for some people with ip6 disabled.
945 Therefore the error check is removed, so they can use the option.
947 19 October 2010: Wouter
948 - Fix for request list growth, if a server has long timeout but the
949 lost counter is low, then its effective rtt is the one without
950 exponential backoff applied. Because the backoff is not working.
951 The lost counter can then increase and the server is blacklisted,
952 or the lost counter does not increase and the server is working
955 18 October 2010: Wouter
956 - iana portlist updated.
958 13 October 2010: Wouter
959 - Fix TCP so it uses a random outgoing-interface.
960 - unbound-anchor handles ADDPEND keystate.
962 11 October 2010: Wouter
963 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
964 the zone has a secure delegation hosted on the same server did not
965 verify as secure (it was insecure by mistake).
966 - iana portlist updated.
967 - ldns tarball updated (for reading cachedumps with bad RR data).
969 1 October 2010: Wouter
970 - test for unbound-anchor. fix for reading certs.
971 - Fix alloc_reg_release for longer uptime in out of memory conditions.
973 28 September 2010: Wouter
974 - unbound-anchor working, it creates or updates a root.key file.
975 Use it before you start the validator (e.g. at system boot time).
977 27 September 2010: Wouter
978 - iana portlist updated.
980 24 September 2010: Wouter
981 - bug#329: in example.conf show correct ipv4 link-local 169.254/16.
983 23 September 2010: Wouter
984 - unbound-anchor app, unbound requires libexpat (xml parser library).
986 22 September 2010: Wouter
987 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
988 reverse ipv6 orchid prefix from builtin list.
989 - iana portlist updated.
991 17 September 2010: Wouter
992 - DLV has downgrade protection again, because the RFC says so.
993 - iana portlist updated.
995 16 September 2010: Wouter
996 - Algorithm rollover operational reality intrudes, for trust-anchor,
997 5011-store, and DLV-anchor if one key matches it's good enough.
998 - iana portlist updated.
999 - Fix reported validation error in out of memory condition.
1001 15 September 2010: Wouter
1002 - Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
1004 14 September 2010: Wouter

1006 like _tcp.slb.com with 262 servers.
1007 - iana portlist updated.
1009 13 September 2010: Wouter
1010 - bug#327: Fix for cannot access stub zones until the root is primed.
1012 9 September 2010: Wouter
1013 - unresponsive servers are not completely blacklisted (because of
1014 firewalls), but also not probed all the time (because of the request
1015 list size it generates). The probe rate is 1%.
1016 - iana portlist updated.
1018 20 August 2010: Wouter
1019 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
1020 iterator get_mem includes priv_get_mem. delegpt nodup removed.
1021 listen_pushback, query_info_allocqname, write_socket, send_packet,
1022 comm_point_set_cb_arg and listen_resume removed.
1024 19 August 2010: Wouter
1025 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
1026 Delegpt structures checked for duplicates always.
1027 No more nameserver lookups generated when depth is full anyway.
1028 - example.conf notes how to do DNSSEC validation and track the root.
1029 - iana portlist updated.
1031 18 August 2010: Wouter
1032 - Fix bug#322: configure does not respect CFLAGS on Solaris.
1033 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
1034 if use sun-cc, but some systems need different flags.
1036 16 August 2010: Wouter
1037 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
1038 changes, uses m4_bpatsubst now.
1039 - make test (or make check) should be more portable and run the unit
1040 test and testbound scripts. (make longtest has special requirements).
1042 13 August 2010: Wouter
1043 - More pleasant remote control command parsing.
1044 - documentation added for return values reported by doxygen 1.7.1.
1045 - iana portlist updated.
1047 9 August 2010: Wouter
1048 - Fix name of rrset printed that failed validation.

1051 - Return NXDOMAIN after chain of CNAMEs ends at name-not-found.
1053 4 August 2010: Wouter
1054 - Fix validation in case a trust anchor enters into a zone with
1055 unsupported algorithms.
1057 3 August 2010: Wouter
1058 - updated ldns tarball with bugfixes.
1059 - release tag 1.4.6.
1060 - trunk becomes 1.4.7 develop.
1061 - iana portlist updated.
1063 22 July 2010: Wouter
1064 - more error details on failed remote control connection.
1066 15 July 2010: Wouter
1067 - rlimit adjustments for select and ulimit can happen at the same time.
1069 14 July 2010: Wouter
1070 - Donation text added to README.
1071 - Fix integer underflow in prefetch ttl creation from cache. This
1072 fixes a potential negative prefetch ttl.
1074 12 July 2010: Wouter
1075 - Changed the defaults for num-queries-per-thread/outgoing-range.
1076 For builtin-select: 512/960, for libevent 1024/4096 and for
1077 windows 24/48 (because of win api). This makes the ratio this way
1078 to improve resilience under heavy load. For high performance, use
1079 libevent and possibly higher numbers.
1081 10 July 2010: Wouter
1082 - GOST enabled if SSL is recent and ldns has GOST enabled too.
1083 - ldns tarball updated.
1086 - iana portlist updated.
1087 - Fix validation of qtype DNSKEY when a key-cache entry exists but
1088 no rr-cache entry is used (it expired or prefetch), it then goes
1089 back up to the DS or trust-anchor to validate the DNSKEY.
1092 - Neat function prototypes, unshadowed local declarations.
1095 - failure to chown the pidfile is not fatal any more.
1096 - testbound uses UTC timezone.
1097 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
1098 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
1101 - log if a server is skipped because it is on the donotquery list,
1102 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
1103 - added feature to print configure date, target and options with -h.
1104 - added feature to print event backend system details with -h.
1105 - wdiff is not actually required by make test, updated requirements.
1108 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
1109 must be signed with all algorithms from the DS rrset at the parent.
1110 This is now checked and becomes bogus if not.
1112 28 June 2010: Wouter
1113 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
1114 in overload situations to be about 5 qps for the class of shortly
1116 The capacity of the resolver is then about (numqueriesperthread / 2)
1117 / (average time for such long queries) qps for long queries.
1118 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
1119 qps for short queries, per thread.
1120 - Fix the max number of reply-address count to be applied for duplicate
1121 queries, and not for new query list entries. This raises the memory
1122 usage to a max of (16+1)*numqueriesperthread reply addresses.
1124 25 June 2010: Wouter
1125 - Fix handling of corner case reply from lame server, follows rfc2308.
1126 It could lead to a nodata reply getting into the cache if the search
1127 for a non-lame server turned up other misconfigured servers.
1128 - unbound.h has extern "C" statement for easier include in c++.
1130 23 June 2010: Wouter
1131 - iana portlist updated.
1132 - makedist upgraded cross compile openssl option, like this:
1133 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
1135 22 June 2010: Wouter
1136 - Unbound reports libev or libevent correctly in logs in verbose mode.
1137 - Fix to unload gost dynamic library module for leak testing.
1139 18 June 2010: Wouter
1140 - iana portlist updated.
1142 17 June 2010: Wouter
1143 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
1145 16 June 2010: Wouter
1146 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
1147 assertion was wrong.
1148 - updated ldns tarball.
1150 15 June 2010: Wouter
1151 - tag 1.4.5 created.
1152 - trunk contains 1.4.6 in development.
1153 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
1154 - Fix to use one pointer less for iterator query state store_parent_NS.
1155 - makedist crosscompile to windows uses builtin ldns not host ldns.
1156 - Max referral count from 30 to 130, because 128 one character domains
1158 - added documentation for the histogram printout to syslog.
1160 11 June 2010: Wouter
1161 - When retry to parent the retrycount is not wiped, so failed
1162 nameservers are not tried again.
1163 - iana portlist updated.
1165 10 June 2010: Wouter
1166 - Fix bug where a long loop could be entered, now cycle detection
1167 has a loop-counter and maximum search amount.
1170 - iana portlist updated.
1171 - 1.4.5rc1 tag created.
1174 - ldns tarball updated, 1.6.5.
1175 - review comments, split dependency cycle tracking for parentside
1176 last resort lookups for A and AAAA so there are more lookup options.
1179 - Fix compile warning if compiled without threads.
1180 - updated ldns-tarball with current ldns svn (pre 1.6.5).
1181 - GOST disabled-by-default, the algorithm number is allocated but the
1182 RFC is still has to pass AUTH48 at the IETF.
1185 - Ignore Z flag in incoming messages too.
1186 - Fix storage of negative parent glue if that last resort fails.
1187 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
1188 - new splint flags for newer splint install.
1191 - Fix AD flag handling, it could in some cases mistakenly copy the AD
1192 flag from upstream servers.
1193 - alloc_special_obtain out of memory is not a fatal error any more,
1194 enabling unbound to continue longer in out of memory conditions.
1195 - parentside names are dispreferred but not said to be dnssec-lame.
1196 - parentside check for cached newname glue.
1197 - fix parentside and querytargets modulestate, for dump_requestlist.
1198 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
1199 - fix parentside from cache to be marked dispreferred for bad names.
1202 - iana portlist updated.
1203 - parent-child disagreement approach altered. Older fixes are
1204 removed in place of a more exhaustive search for misconfigured data
1205 available via the parent of a delegation.
1206 This is designed to be throttled by cache entries, with TTL from the
1207 parent if possible. Additionally the loop-counter is used.
1208 It also tests for NS RRset differences between parent and child.
1209 The fetch of misconfigured data should be more reliable and thorough.
1210 It should work reliably even with no or only partial data in cache.
1211 Data received from the child (as always) is deemed more
1212 authoritative than information received from the delegation parent.
1213 The search for misconfigured data is not performed normally.
1216 - Contribution from Migiel de Vos (Surfnet): nagios patch for
1217 unbound-host, in contrib/ (in the source tarball). Makes
1218 unbound-host suitable for monitoring dnssec(-chain) status.
1221 - EDNS timeout code will not fire if EDNS status already known.
1222 - EDNS failure not stored if EDNS status known to work.
1225 - Fix resolution for domains like safesvc.com.cn. If the iterator
1226 can not recurse further and it finds the delegation in a state
1227 where it would otherwise have rejected it outhand if so received
1228 from a cache lookup, then it can try to ask higherup (with loop
1230 - Fix comments in iter_utils:dp_is_useless.
1233 - Fix various compiler warnings from the clang llvm compiler.
1234 - iana portlist updated.
1237 - Fix bug#308: spelling error in variable name in parser and lexer.
1240 - Fix dnssec-missing detection that was turned off by server selection.
1241 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
1242 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
1243 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
1245 29 April 2010: Wouter
1246 - Fix for dnssec lameness detection to use the key cache.
1247 - infra cache entries that are expired are wiped clean. Previously
1248 it was possible to not expire host data (if accessed often).
1250 28 April 2010: Wouter
1251 - ldns tarball updated and GOST support is detected and then enabled.
1252 - iana portlist updated.
1253 - Fix detection of gost support in ldns (reported by Chris Smith).
1255 27 April 2010: Wouter
1256 - unbound-control get_option domain-insecure shows config file items.
1257 - fix retry sequence if prime hints are recursion-lame.
1258 - autotrust anchor file can be initialized with a ZSK key as well.
1259 - harden-referral-path does not result in failures due to max-depth.
1260 You can increase the max-depth by adding numbers (' 0') after the
1261 target-fetch-policy, this increases the depth to which is checked.
1263 26 April 2010: Wouter
1264 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
1265 CPPFLAGS during configure process.
1266 - if libev is installed on the base system (not libevent), detect
1267 it from the event.h header file and link with -lev.
1268 - configlexer.lex gets config.h, and configyyrename.h added by make,
1269 no more double include.
1270 - More strict scrubber (Thanks to George Barwood for the idea):
1271 NS set must be pertinent to the query (qname subdomain nsname).
1272 - Fix bug#307: In 0x20 backoff fix fallback so the number of
1273 outstanding queries does not become -1 and block the request.
1274 Fixed handling of recursion-lame in combination with 0x20 fallback.
1275 Fix so RRsets are compared canonicalized and sorted if the immediate
1276 comparison fails, this makes it work around round-robin sites.
1278 23 April 2010: Wouter
1279 - Squelch log message: sendto failed permission denied for
1280 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
1281 - Fix to fetch data as last resort more tenaciously. When cycle
1282 targets cause the server selection to believe there are more options
1283 when they really are not there, the server selection is reinitiated.
1284 - Fix fetch from blacklisted dnssec lame servers as last resort. The
1285 server's IP address is then given in validator errors as well.
1286 - Fix local-zone type redirect that did not use the query name for
1289 22 April 2010: Wouter
1291 - trunk contains 1.4.5 in development.
1292 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
1293 The validator error message was 'no signatures from ...'.
1295 16 April 2010: Wouter
1296 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
1299 15 April 2010: Wouter
1300 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
1301 example key and signatures for GOST. GOST requires openssl-1.0.0.
1302 GOST is still disabled by default.
1304 9 April 2010: Wouter
1305 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
1306 get into an endless loop, if 0x20 was enabled, and buffers are small
1307 or particular broken packets are received.
1308 - Fix chain of trust with CNAME at an intermediate step, for the DS
1311 8 April 2010: Wouter
1312 - Fix validation of queries with wildcard names (*.example).
1314 6 April 2010: Wouter
1315 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
1316 cache timeout coincided with a server update, the current EDNS
1317 backoff is less sensitive, and does not cache the backoff unless
1318 the backoff actually works and the domain is not expecting DNSSEC.
1319 - GOST support with correct algorithm numbers.
1321 1 April 2010: Wouter
1322 - iana portlist updated.
1324 24 March 2010: Wouter
1325 - unbound control flushed items are not counted when flushed again.
1327 23 March 2010: Wouter
1328 - iana portlist updated.
1330 22 March 2010: Wouter
1331 - unbound-host disables use-syslog from config file so that the
1332 config file for the main server can be used more easily.
1333 - fix bug#301: unbound-checkconf could not parse interface
1334 '0.0.0.0@5353', even though unbound itself worked fine.
1336 19 March 2010: Wouter
1337 - fix fwd_ancil test to pass if the socket options are not supported.
1339 18 March 2010: Wouter
1340 - Fixed random numbers for port, interface and server selection.
1341 Removed very small bias.
1342 - Refer to the listing in unbound-control man page in the extended
1343 statistics entry in the unbound.conf man page.
1345 16 March 2010: Wouter
1346 - Fix interface-automatic for OpenBSD: msg.controllen was too small,
1347 also assertions on ancillary data buffer.
1348 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
1349 - for NSEC3 check if signatures are cached.
1351 15 March 2010: Wouter
1352 - unit test for util/regional.c.
1354 12 March 2010: Wouter
1355 - Reordered configure checks so fork and -lnsl -lsocket checks are
1356 earlier, and thus later checks benefit from and do not hinder them.
1357 - iana portlist updated.
1358 - ldns tarball updated.
1359 - Fix python use when multithreaded.
1360 - Fix solaris python compile.
1361 - Include less in config.h and include per code file for ldns, ssl.
1363 11 March 2010: Wouter
1364 - another memory allocation option: --enable-alloc-nonregional.
1365 exposes the regional allocations to other memory purifiers.
1366 - fix for memory alignment in struct sock_list allocation.
1367 - Fix for MacPorts ldns without ssl default, unbound checks if ldns
1368 has dnssec functionality and uses the builtin if not.
1369 - Fix daemonize on Solaris 10, it did not detach from terminal.
1370 - tag 1.4.3 created.
1371 - trunk is 1.4.4 in development.
1372 - spelling fix in validation error involving cnames.
1374 10 March 2010: Wouter
1375 - --enable-alloc-lite works with test set.
1376 - portability in the testset: printf format conversions, prototypes.
1378 9 March 2010: Wouter
1379 - tag 1.4.2 created.
1380 - trunk is 1.4.3 in development.
1381 - --enable-alloc-lite debug option.
1383 8 March 2010: Wouter
1384 - iana portlist updated.
1386 4 March 2010: Wouter
1387 - Fix crash in control channel code.
1389 3 March 2010: Wouter
1390 - better casts in pipe code, brackets placed wrongly.
1391 - iana portlist updated.
1393 1 March 2010: Wouter
1394 - make install depends on make all.
1395 - Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
1396 - --enable-checking: enables assertions but does not look nonproduction.
1397 - nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
1398 nxdomain and nodata distinguished.
1399 - ldns tarball updated.
1400 - --disable-rpath fixed for libtool not found errors.
1401 - new fedora specfile from Fedora13 in contrib from Paul Wouters.
1403 26 February 2010: Wouter
1404 - Fixup prototype for lexer cleanup in daemon code.
1405 - unbound-control list_stubs, list_forwards, list_local_zones and
1408 24 February 2010: Wouter
1409 - Fix scrubber bug that potentially let NS records through. Reported
1411 - Also delete potential poison references from additional.
1412 - Fix: no classification of a forwarder as lame, throw away instead.
1414 23 February 2010: Wouter
1415 - libunbound ub_ctx_get_option() added.
1416 - unbound-control set_option and get_option commands.
1417 - iana portlist updated.
1419 18 February 2010: Wouter
1420 - A little more strict DS scrubbing.
1421 - No more blacklisting of unresponsive servers, a 2 minute timeout
1423 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.
1424 - pickup ldns compile fix, libdl for libcrypto.
1425 - log 'tcp connect: connection timed out' only in high verbosity.
1426 - unbound-control log_reopen command.
1427 - moved get_option code from unbound-checkconf to util/config_file.c
1429 17 February 2010: Wouter
1430 - Disregard DNSKEY from authority section for chain of trust.
1431 DS records that are irrelevant to a referral scrubbed. Anti-poison.
1432 - iana portlist updated.
1434 16 February 2010: Wouter
1435 - Check for 'no space left on device' (or other errors) when
1436 writing updated autotrust anchors and print errno to log.
1438 15 February 2010: Wouter
1439 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
1440 hardcoded. We made the choice to send out more conservatively,
1441 protecting against an aggregate effect more than protecting a
1442 single user (from their own folly, perhaps in case of misconfig).
1444 12 February 2010: Wouter
1445 - Re-query pattern changed on validation failure. To protect troubled
1446 authority servers, unbound caches a failure for the DNSKEY or DS
1447 records for the entire zone, and only retries that 900 seconds later.
1448 This implies that only a handful of packets are sent extra to the
1449 authority if the zone fails.
1451 11 February 2010: Wouter
1452 - ldns tarball update for long label length syntax error fix.
1453 - iana portlist updated.
1455 9 February 2010: Wouter
1456 - Fixup in compat snprintf routine, %f 1.02 and %g support.
1457 - include math.h for testbound test compile portability.
1459 2 February 2010: Wouter
1460 - Updated url of IANA itar, interim trust anchor repository, in script.
1462 1 February 2010: Wouter
1463 - iana portlist updated.
1464 - configure test for memcmp portability.
1466 27 January 2010: Wouter
1467 - removed warning on format string in validator error log statement.
1468 - iana portlist updated.
1470 22 January 2010: Wouter
1471 - libtool finish the install of unbound python dynamic library.
1473 21 January 2010: Wouter
1474 - acx_nlnetlabs.m4 synchronised with nsd's version.
1476 20 January 2010: Wouter
1477 - Fixup lookup trouble for parent-child domains on the first query.
1479 14 January 2010: Wouter
1480 - Fixup ldns detection to also check for header files.
1482 13 January 2010: Wouter
1483 - prefetch-key option that performs DNSKEY queries earlier in the
1484 validation process, and that could halve the latency on DNSSEC
1485 queries. It takes some extra processing (CPU, a cache is needed).
1487 12 January 2010: Wouter
1488 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
1490 8 January 2010: Wouter
1491 - Fix for parent-child disagreement code which could have trouble
1492 when (a) ipv6 was disabled and (b) the TTL for parent and child
1493 were different. There were two bugs, the parent-side information
1494 is fixed to no longer block lookup of child side information and
1495 the iterator is fixed to no longer attempt to get ipv6 when it is
1496 not enabled and then give up in failure.
1497 - test and fixes to make prefetch actually store the answer in the
1498 cache. Considers some rrsets 'already expired' but does not allow
1499 overwriting of rrsets considered more secure.
1501 7 January 2010: Wouter
1502 - Fixup python documentation (thanks Leo Vandewoestijne).
1503 - Work on cache prefetch feature.
1504 - Stats for prefetch, in log print stats, unbound-control stats
1505 and in unbound_munin plugin.
1507 6 January 2010: Wouter
1508 - iana portlist updated.
1509 - bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.
1510 - verbose output includes parent-side-address notion for lameness.
1511 - documented val-log-level: 2 setting in example.conf and man page.
1512 - change unbound-control-setup from 1024(sha1) to 1536(sha256).
1514 1 January 2010: Wouter
1515 - iana portlist updated.
1517 22 December 2009: Wouter
1518 - configure with newer libtool 2.2.6b.
1520 17 December 2009: Wouter
1523 - trunk to version 1.4.2.
1525 15 December 2009: Wouter
1526 - Answer to qclass=ANY queries, with class IN contents.
1527 Test that validation also works.
1528 - updated ldns snapshot tarball with latest fixes (parsing records).
1530 11 December 2009: Wouter
1531 - on IPv4 UDP turn off DF flag.
1533 10 December 2009: Wouter
1534 - requirements.txt updated with design choice explanations.
1535 - Reading fixes: fix to set unlame when child confirms parent glue,
1536 and fix to avoid duplicate addresses in delegation point.
1537 - verify_rrsig routine checks expiration last.
1539 9 December 2009: Wouter
1540 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
1541 errors generated for domain names like '.example.com'.
1542 - Fix SOA excluded from negative DS responses. Reported by Hauke
1543 Lampe. The negative cache did not include proper SOA records for
1544 negative qtype DS responses which makes BIND barf on it, such
1545 responses are now only used internally.
1546 - Fix negative cache lookup of closestencloser check of DS type bit.
1548 8 December 2009: Wouter
1549 - Fix for lookup of parent-child disagreement domains, where the
1550 parent-side glue works but it does not provide proper NS, A or AAAA
1551 for itself, fixing domains such as motorcaravanners.eu.
1552 - Feature: you can specify a port number in the interface: line, so
1553 you can bind the same interface multiple times at different ports.
1555 7 December 2009: Wouter
1556 - Bug#287: Fix segfault when unbound-control remove nonexistent local
1557 data. Added check to tests.
1559 1 December 2009: Wouter
1560 - Fix crash with module-config "iterator".
1561 - Added unit test that has "iterator" module-config.
1563 30 November 2009: Wouter

1566 26 November 2009: Wouter
1567 - updated ldns with release candidate for version 1.6.3.
1568 - tag for 1.4.0 release.
1569 - 1.4.1 version in trunk.
1570 - Fixup major libtool version to 2 because of why_bogus change.
1571 It was 1:5:0 but should have been 2:0:0.
1573 23 November 2009: Wouter
1574 - Patch from David Hubbard for libunbound manual page.
1575 - Fixup endless spinning in unbound-control stats reported by
1576 Attila Nagy. Probably caused by clock reversal.
1578 20 November 2009: Wouter
1579 - contrib/split-itar.sh contributed by Tom Hendrikx.
1581 19 November 2009: Wouter
1582 - better argument help for unbound-control.

1595 13 November 2009: Wouter
1596 - Fixed validation failure for CNAME to optout NSEC3 nodata answer.
1597 - unbound-host does not fail on type ANY.
1598 - Fixed wireparse failure to put RRSIGs together with data in some
1599 long ANY mix cases, which fixes validation failures.
1601 12 November 2009: Wouter
1602 - iana portlist updated.
1603 - fix manpage errors reported by debian lintian.
1605 - fixup very long vallog2 level error strings.
1607 11 November 2009: Wouter
1608 - ldns tarball updated (to 1.6.2).
1611 10 November 2009: Wouter
1612 - Thanks to Surfnet found bug in new dnssec-retry code that failed
1613 to combine well when combined with DLV and a particular failure.
1614 - Fixed unbound-control -h output about argument optionality.
1617 5 November 2009: Wouter
1618 - lint fixes and portability tests.
1619 - better error text for multiple domain keys in one autotrust file.
1621 2 November 2009: Wouter
1622 - Fix bug where autotrust does not work when started with a DS.
1623 - Updated GOST unit tests for unofficial algorithm number 249
1624 and DNSKEY-format changes in draft version -01.
1626 29 October 2009: Wouter
1627 - iana portlist updated.
1628 - edns-buffer-size option, default 4096.
1631 28 October 2009: Wouter
1632 - removed abort on prealloc failure, error still printed but softfail.
1633 - iana portlist updated.
1634 - RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
1635 - ldns tarball updated (which also enables rsasha256 support).
1637 27 October 2009: Wouter
1638 - iana portlist updated.
1640 8 October 2009: Wouter
1642 - add val-log-level print to corner case (nameserver.epost.bg).
1643 - more detail to errors from insecure delegation checks.
1644 - Fix double time subtraction in negative cache reported by
1645 Amanda Constant and Hugh Mahon.
1646 - Made new validator error string available from libunbound for
1647 applications. It is in result->why_bogus, a zero-terminated string.
1648 unbound-host prints it by default if a result is bogus.
1649 Also the errinf is public in module_qstate (for other modules).
1651 7 October 2009: Wouter
1652 - retry for validation failure in DS and prime results. Less mem use.
1653 unit test. Provisioning in other tests for requeries.
1654 - retry for validation failure in DNSKEY in middle of chain of trust.
1656 - retry for empty non terminals in chain of trust and unit test.
1657 - Fixed security bug where the signatures for NSEC3 records were not
1658 checked when checking for absence of DS records. This could have
1659 enabled the substitution of an insecure delegation.
1660 - moved version number to 1.4.0 because of 1.3.4 release with only
1661 the NSEC3 patch from the entry above.
1662 - val-log-level: 2 shows extended error information for validation
1663 failures, but still one (longish) line per failure. For example:
1664 validation failure <example.com. DNSKEY IN>: signature expired from
1665 192.0.2.4 for trust anchor example.com. while building chain of trust
1666 validation failure <www.example.com. A IN>: no signatures from
1667 192.0.2.6 for key example.com. while building chain of trust
1669 6 October 2009: Wouter
1670 - Test set updated to provide additional ns lookup result.
1671 The retry would attempt to fetch the data from other nameservers
1672 for bogus data, and this needed to be provisioned in the tests.
1674 5 October 2009: Wouter
1675 - first validation failure retry code. Retries for data failures.
1678 2 October 2009: Wouter
1679 - improve 5011 modularization.
1680 - fix unbound-host so -d can be given before -C.
1681 - iana portlist updated.
1683 28 September 2009: Wouter
1684 - autotrust-anchor-file can read multiline input and $ORIGIN.
1685 - prevent integer overflow in holddown calculation. review fixes.
1686 - fixed race condition in trust point revocation. review fix.
1687 - review fixes to comments, removed unused code.
1689 25 September 2009: Wouter
1690 - so-rcvbuf: 4m option added. Set this on large busy servers to not
1691 drop the occasional packet in spikes due to full socket buffers.
1692 netstat -su keeps a counter of UDP dropped due to full buffers.
1693 - review of validator/autotrust.c, small fixes and comments.
1695 23 September 2009: Wouter
1696 - 5011 query failed counts verification failures, not lookup failures.
1697 - 5011 probe failure handling fixup.
1698 - test unbound reading of original autotrust data.
1699 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
1700 picked up, otherwise performs initial probe like usual.
1702 22 September 2009: Wouter
1703 - autotrust test with algorithm rollover, new ordering of checks
1704 assists in orderly rollover.
1705 - autotrust test with algorithm rollover to unknown algorithm.
1706 checks if new keys are supported before adding them.
1707 - autotrust test with trust point revocation, becomes unsigned.
1708 - fix DNSSEC-missing-signature detection for minimal responses
1709 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
1711 18 September 2009: Wouter
1712 - autotrust tests, fix trustpoint timer deletion code.
1713 fix count of valid anchors during missing remove.
1714 - autotrust: pick up REVOKE even if not signed with known other keys.
1716 17 September 2009: Wouter
1717 - fix compile of unbound-host when --enable-alloc-checks.
1718 - Fix lookup problem reported by Koh-ichi Ito and Jaap Akkerhuis.
1719 - Manual page fixes reported by Tony Finch.
1721 16 September 2009: Wouter
1722 - Fix memory leak reported by Tao Ma.
1723 - Fix memstats test tool for log-time-ascii log format.
1725 15 September 2009: Wouter
1726 - iana portlist updated.
1728 10 September 2009: Wouter
1729 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
1730 - use linebuffering for log-file: output, this can be significantly
1731 faster than the previous fflush method and enable some class of
1732 resolvers to use high verbosity (for short periods).
1733 Not on windows, because line buffering does not work there.
1735 9 September 2009: Wouter
1736 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
1737 The RRsets would still expire at the normal time, but this would
1738 keep messages bogus in the cache for too long.
1739 - regression test for that bug.
1740 - documented that load_cache is meant for debugging.
1742 8 September 2009: Wouter
1743 - fixup printing errors when load_cache, they were printed to the
1744 SSL connection which broke, now to the log.
1745 - new ldns - with fixed parse of large SOA values.
1747 7 September 2009: Wouter
1748 - autotrust testbound scenarios.
1749 - autotrust fix that failure count is written to file.
1750 - autotrust fix that keys may become valid after add holddown time
1751 alone, before the probe returns.
1753 4 September 2009: Wouter
1754 - Changes to make unbound work with libevent-2.0.3 alpha. (in

1995 going to higher zones when looking up the right forward or stub
1996 server. This makes a stub pointing to a local server that has
1997 a local view of example.com signed with the same keys as are
1998 publicly used work. Reported by Johan Ihren.

2000 Dennis DeDonatis. It converts /etc/hosts into config statements.
2001 - same thing fixed for forward-zone and DS, chain of trust from
2002 public internet into the forward-zone works now. Added unit test.
2005 - openssl key files are opened apache-style, when user is root and
2006 before chrooting. This makes permissions on remote-control key
2007 files easier to set up. Fixes bug #251.
2008 - flush_type and flush_name remove msg cache entries.
2009 - codereview - dp copy bogus setting fix.

2025 - review comments from Matthijs.
2028 - --enable-sha2 option. The draft rsasha256 changed its algorithm

2030 RSASHA256 and RSASHA512 support by default.
2031 - ldns trunk included as new tarball.
2032 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.

2044 Unbound would try to re-use ports that came free, but this is
2045 of course not really possible because everything is deleted.
2046 Most easily triggered on XP (not Vista), maybe because of the
2047 network stack encouraging large messages backlogs.
2048 - change in debug statements.
2049 - Fixed bug that could cause a crash if root prime failed when there
2050 were message backlogs.

2125 - nxdomain ttl considerations in requirements.txt
2127 3 April 2009: Wouter
2128 - Fixed a bug that caused messages to be stored in the cache too
2129 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
2130 targets have been more vulnerable to the TTL miscalculation bug.

2298 security is provided by pgp signature.
2300 18 February 2009: Wouter
2301 - more cycle detection. Also for target queries.
2302 - fixup bug where during deletion of the mesh queries the callbacks
2303 that were reentrant caused assertion failures. Keep the mesh in
2304 a reentrant safe state. Affects libunbound, reload of server,
2305 on quit and flush_requestlist.
2306 - iana portlist updated.
2308 13 February 2009: Wouter
2309 - forwarder information now per-thread duplicated.
2310 This keeps it read only for speed, with no locking necessary.
2311 - forward command for unbound control to change forwarders to use
2313 - document that unbound-host reads no config file by default.
2314 - updated iana portlist.
2316 12 February 2009: Wouter
2317 - call setusercontext if available (on BSD).
2318 - small refactor of stats clearing.
2319 - #227: flush_stats feature for unbound-control.
2320 - stats_noreset feature for unbound-control.
2321 - flush_requestlist feature for unbound-control.
2322 - libunbound version upped API (was changed 5 feb).
2323 - unbound-control status shows if root forwarding is in use.
2324 - slightly nicer memory management in iter-fwd code.
2326 10 February 2009: Wouter
2327 - keys with rfc5011 REVOKE flag are skipped and not considered when
2329 - iana portlist updated
2330 - #226: dump_requestlist feature for unbound-control.
2332 6 February 2009: Wouter
2333 - contrib contains specfile for fedora 1.2.1 (from Paul Wouters).
2334 - iana portlist updated.
2335 - fixup EOL in include directive (reported by Paul Wouters).
2336 You can no longer specify newlines in the names of included files.
2337 - config parser changed. Gives some syntax errors closer to where they
2338 occurred. Does not enforce a space after keyword anymore.
2339 Does not allow literal newlines inside quoted strings anymore.
2340 - verbosity level 5 logs customer IP for new requestlist entries.
2341 - test fix, lexer and cancel test.
2342 - new option log-time-ascii: yes if you enable it prints timestamps
2343 in the log file as Feb 06 13:45:26 (like syslog does).
2344 - detect event_base_new in libevent-1.4.1 and later and use it.
2345 - #231 unbound-checkconf -o option prints that value from config file.
2346 Useful for scripting in management scripts and the like.
2348 5 February 2009: Wouter
2349 - ldns 1.5.0 rc as tarball included.
2350 - 1.3.0 development continues:
2351 change in libunbound API: ub_cancel can return an error, that
2352 the async_id did not exist, or that it was already delivered.
2353 The result could have been delivered just before the cancel
2354 routine managed to acquire the lock, so a caller may get the
2355 result at the same time they call cancel. For this case,
2356 ub_cancel tries to return an error code.
2357 Fixes race condition in ub_cancel() libunbound function.
2358 - MacOSX Leopard cleaner text output from configure.
2359 - initgroups(3) is called to drop secondary group permissions, if
2361 - configure option --with-ldns-builtin forces the use of the
2362 inluded ldns package with the unbound source. The -I include
2363 is put before the others, so it avoids bad include files from
2364 an older ldns install.
2365 - daemon(3) posix call is used when available.
2366 - testbound test for older fix added.
2368 4 February 2009: Wouter
2369 - tag for release 1.2.1.
2370 - trunk setup for 1.3.0 development.
2372 3 February 2009: Wouter
2373 - noted feature requests in doc/TODO.
2374 - printout more detailed errors on ssl certificate loading failures.
2375 - updated IANA portlist.
2377 16 January 2009: Wouter
2378 - more quiet about ipv6 network failures, i.e. when ipv6 is not
2379 available (network unreachable). Debug still printed on high
2381 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
2382 debugging with unbound-host -4 -d ...
2383 - more cycle detection for NS-check, addr-check, root-prime and
2384 stub-prime queries in the iterator. Avoids possible deadlock
2387 15 January 2009: Wouter
2388 - bug #229: fixup configure checks for compilation with Solaris
2389 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc
2390 - fixup suncc warnings.
2391 - fix bug where unbound could crash using libevent 1.3 and older.
2392 - update testset for recent retry change.
2394 14 January 2009: Wouter
2395 - 1.2.1 feature: negative caching for failed queries.
2396 Queries that failed are cached for 5 seconds (NORR_TTL).
2397 If the failure is local, like out of memory, it is not cached.
2398 - the TTL comparison for the cache used different comparisons,
2399 causing many cache responses that used the iterator and validator
2400 state machines unnecessarily.
2401 - retry from 4 to 5 so that EDNS drop retry is part of the first
2402 query resolve attempt, and cached error does not stop EDNS fallback.
2403 - remove debug prints that protect against bad referrals.
2404 - honor QUIET=no on make commandline (or QUIET=yes ).
2406 13 January 2009: Wouter
2407 - fixed bug in lameness marking, removed printouts.
2408 - find NS rrset more cleanly for qtype NS.
2409 - Moved changes to 1.2.0 for release. Thanks to Mark Zealey for
2411 - 1.2.1 feature: stops resolving AAAAs promiscuously when they
2412 are in the negative cache.
2414 12 January 2009: Wouter
2415 - fixed bug in infrastructure lameness cache, did not lowercase
2416 name of zone to hash when setting lame.
2417 - lameness debugging printouts.
2419 9 January 2009: Wouter
2420 - created svn tag for 1.2.0 release.
2421 - svn trunk contains 1.2.1 version number.
2422 - iana portlist updated for todays list.
2423 - removed debug print.
2425 8 January 2009: Wouter
2426 - new version of ldns-trunk (today) included as tarball, fixed
2427 bug #224, building with -j race condition.
2428 - remove possible race condition in the test for race conditions.
2430 7 January 2009: Wouter
2431 - version 1.2.0 in preparation.
2432 - feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
2433 statements. (Adapted from patch by Paul Wouters).
2434 - typo fix and iana portlist updated.
2435 - porting testsuite; unused var warning, and type fixup.
2437 6 January 2009: Wouter
2438 - fixup packet-of-death when compiled with --enable-debug.
2439 A malformed packet could cause an internal assertion failure.
2440 - added test for HINFO canonicalisation behaviour.
2441 - fixup reported problem with transparent local-zone data where
2442 queries with different type could get nxdomain. Now queries
2443 with a different name get resolved normally, with different type
2444 get a correct NOERROR/NODATA answer.
2445 - HINFO no longer downcased for validation, making unbound compatible
2447 - fix reading included config files when chrooted.
2448 Give full path names for include files.
2449 Relative path names work if the start dir equals the working dir.
2450 - fix libunbound message transport when no packet buffer is available.
2452 5 January 2009: Wouter
2453 - fixup getaddrinfo failure handling for remote control port.
2454 - added L.ROOT-SERVERS.NET. AAAA 2001:500:3::42 to builtin root hints.
2455 - fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
2456 - comm_timer_set performs base_set operation after event_add.
2458 18 December 2008: Wouter
2459 - fixed bug reported by Duane Wessels: error in DLV lookup, would make
2460 some zones that had correct DLV keys as insecure.
2461 - follows -rc makedist from ldns changes (no _rc).
2462 - ldns tarball updated with 1.4.1rc for DLV unit test.
2463 - verbose prints about recursion lame detection and server selection.
2464 - fixup BSD port for infra host storage. It hashed wrongly.
2465 - fixup makedist snapshot name generation.
2466 - do not reopen syslog to avoid dev/log dependency.
2468 17 December 2008: Wouter
2469 - follows ldns makedist.sh. -rc option. autom4te dir removed.
2470 - unbound-control status command.
2471 - extended statistics has a number of ipv6 queries counter.
2472 contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
2474 16 December 2008: Wouter
2475 - follow makedist improvements from ldns, for maintainers prereleases.
2476 - snapshot version uses _ not - to help rpm distinguish the
2479 11 December 2008: Wouter
2480 - better fix for bug #219: use LOG_NDELAY with openlog() call.
2481 Thanks to Tamas Tevesz.
2483 9 December 2008: Wouter
2484 - bug #221 fixed: unbound checkconf checks if key files exist if
2485 remote control is enabled. Also fixed NULL printf when not chrooted.
2486 - iana portlist updated.
2488 3 December 2008: Wouter
2489 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
2490 freezes up unbound if this was compiled without threading, and
2491 was using multiple processes.
2492 - iana portlist updated.
2493 - test for remote control with interprocess communication.
2494 - created command distribution mechanism so that remote control
2495 commands other than 'stats' work on all processes in a nonthreaded
2496 compiled version. dump/load cache work, on the first process.
2497 - fixup remote control local_data addition memory corruption bug.
2499 1 December 2008: Wouter
2500 - SElinux policy files in contrib/selinux for the unbound daemon,
2501 by Paul Wouters and Adam Tkac.
2503 25 November 2008: Wouter
2504 - configure complains when --without-ssl is given (bug #220).
2505 - skip unsupported feature tests on vista/mingw.
2506 - fixup testcode/streamtcp to work on vista/mingw.
2507 - root-hints test checks version of dig required.
2508 - blacklisted servers are polled at a low rate (1%) to see if they
2509 come back up. But not if there is some other working server.
2511 24 November 2008: Wouter
2512 - document that the user of the server daemon needs read privileges
2513 on the keys and certificates generated by unbound-control-setup.
2514 This is different per system or distribution, usually, running the
2515 script under the same username as the server uses suffices.
2516 i.e. sudo -u unbound unbound-control-setup
2517 - testset port to vista/mingw.
2518 - tcp_sigpipe to freebsd port.
2520 21 November 2008: Wouter
2521 - fixed tcp accept, errors were printed when they should not.
2522 - unbound-control-setup.sh removes read/write permissions other
2523 from the keys it creates (as suggested by Dmitriy Demidov).
2525 20 November 2008: Wouter
2526 - fixup fatal error due to faulty error checking after tcp accept.
2527 - add check in rlimit to avoid integer underflow.
2528 - rlimit check with new formula; better estimate for number interfaces
2529 - nicer comments in rlimit check.
2530 - tag 1.1.1 created in svn.
2531 - trunk label is 1.1.2
2533 19 November 2008: Wouter
2534 - bug #219: fixed so that syslog which delays opening until the first
2535 log line is written, gets a log line while not chroot'ed yet.
2537 18 November 2008: Wouter
2538 - iana portlist updated.
2539 - removed cast in unit test debug print that was not 64bit safe.
2540 - trunk back to 1.1.0; copied to tags 1.1.0 release.
2541 - trunk to has version number 1.1.1 again.
2542 - in 1.1.1; make clean nicer. grammar in manpage.
2544 17 November 2008: Wouter
2545 - theoretical fix for problems reported on mailing list.
2546 If a delegation point has no A but only AAAA and do-ip6 is no,
2547 resolution would fail. Fixed to ask for the A and AAAA records.
2548 It has to ask for both always, so that it can fail quietly, from
2549 TLD perspective, when a zone is only reachable on one transport.
2550 - test for above, only AAAA and doip6 is no. Fix causes A record
2551 for nameserver to be fetched.
2552 - fixup address duplication on cache fillup for delegation points.
2553 - testset updated for new query answer requirements.
2555 14 November 2008: Wouter
2556 - created 1.1.0 release tag in svn.
2557 - trunk moved to 1.1.1
2558 - fixup unittest-neg for locking.
2560 13 November 2008: Wouter
2561 - added fedora init and specfile to contrib (by Paul Wouters).
2562 - added configure check for ldns 1.4.0 (using its compat funcs).
2563 - neater comments in worker.h.
2564 - removed doc/plan and updated doc/TODO.
2565 - silenced EHOSTDOWN (verbosity 2 or higher to see it).
2566 - review comments from Jelte, Matthijs. Neater code.
2568 12 November 2008: Wouter
2569 - add unbound-control manpage to makedist replace list.
2571 11 November 2008: Wouter
2572 - unit test for negative cache, stress tests the refcounting.
2573 - fix for refcounting error that could cause fptr_wlist fatal exit
2574 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
2575 Attila Nagy for testing).
2576 - nicer comments in cachedump about failed RR to string conversion.
2577 - fix 32bit wrap around when printing large (4G and more) mem usage
2578 for extended statistics.
2580 10 November 2008: Wouter
2581 - fixup the getaddrinfo compat code rename.
2583 8 November 2008: Wouter
2584 - added configure check for eee build warning.

2587 - fix bug 217: fixed, setreuid and setregid do not work on MacOSX10.4.
2588 - detect nonblocking problems in network stack in configure script.
2590 6 November 2008: Wouter
2591 - dname_priv must decompress the name before comparison.
2592 - iana portlist updated.
2594 5 November 2008: Wouter
2595 - fixed possible memory leak in key_entry_key deletion.
2596 Would leak a couple bytes when trust anchors were replaced.
2597 - if query and reply qname overlap, the bytes are skipped not copied.
2598 - fixed file descriptor leak when messages were jostled out that
2599 had outstanding (TCP) replies.
2600 - DNAMEs used from cache have their synthesized CNAMEs initialized
2602 - fixed file descriptor leak for localzone type deny (for TCP).
2603 - fixed memleak at exit for nsec3 negative cached zones.
2604 - fixed memleak for the keyword 'nodefault' when reading config.
2605 - made verbosity of 'edns incapable peer' warning higher, so you
2606 do not get spammed by it.
2607 - caught elusive Bad file descriptor error bug, that would print the
2608 error while unnecessarily try to listen to a closed fd. Fixed.
2610 4 November 2008: Wouter
2611 - fixed -Wwrite-strings warnings that result in better code.
2613 3 November 2008: Wouter
2614 - fixup build process for Mac OSX linker, use ldns b32 compat funcs.
2615 - generated configure with autoconf-2.61.
2616 - iana portlist updated.
2617 - detect if libssl needs libdl. For static linking with libssl.
2618 - changed to use new algorithm identifiers for sha256/sha512
2619 from ldns 1.4.0 (need very latest version).
2620 - updated the included ldns tarball.
2621 - proper detection of SHA256 and SHA512 functions (not just sizes).
2623 23 October 2008: Wouter
2624 - a little more debug info for failure on signer names. prints names.
2626 22 October 2008: Wouter
2627 - CFLAGS are picked up by configure from the environment.
2628 - iana portlist updated.
2629 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
2630 - new stub-prime: yesno option. Default is off, so it does not prime.
2631 can be turned on to get same behaviour as previous unbound release.
2632 - made automated test that checks if builtin root hints are uptodate.
2633 - finished draft-wijngaards-dnsext-resolver-side-mitigation
2634 implementation. The unwanted-reply-threshold can be set.
2635 - fixup so fptr_whitelist test in alloc.c works.
2637 21 October 2008: Wouter
2638 - fix update-anchors.sh, so it does not report different RR order
2639 as an update. Sorts the keys in the file. Updated copyright.
2640 - fixup testbound on windows, the command control pipe doesn't exist.
2641 - skip 08hostlib test on windows, no fork() available.
2642 - made unbound-remote work on windows.
2644 20 October 2008: Wouter
2645 - quench a log message that is debug only.
2646 - iana portlist updated.
2647 - do not query bogus nameservers. It is like nameservers that have
2648 the NS or A or AAAA record bogus are listed as donotquery.
2649 - if server selection is faced with only bad choices, it will
2650 attempt to get more options to be fetched.
2651 - changed bogus-ttl default value from 900 to 60 seconds.
2652 In anticipation that operator caused failures are more likely than
2653 actual attacks at this time. And thus repeated validation helps
2654 the operators get the problem fixed sooner. It makes validation
2655 failures go away sooner (60 seconds after the zone is fixed).
2656 Also it is likely to try different nameserver targets every minute,
2657 so that if a zone is bad on one server but not another, it is
2658 likely to pick up the 'correct' one after a couple minutes,
2659 and if the TTL is big enough that solves validation for the zone.
2660 - fixup unbound-control compilation on windows.
2662 17 October 2008: Wouter
2663 - port Leopard/G5: fixup type conversion size_t/uint32.
2664 please ranlib, stop file without symbols warning.
2665 - harden referral path now also validates the root after priming.
2666 It looks up the root NS authoritatively as well as the root servers
2667 and attemps to validate the entries.
2669 16 October 2008: Wouter
2670 - Fixup negative TTL values appearing (reported by Attila Nagy).
2672 15 October 2008: Wouter
2673 - better documentation for 0x20; remove fallback TODO, it is done.
2674 - harden-referral-path feature includes A, AAAA queries for glue,
2675 as well as very careful NS caching (only when doing NS query).
2676 A, AAAA use the delegation from the NS-query.
2678 14 October 2008: Wouter
2679 - fwd_three.tpkg test was flaky. If the three requests hit the
2680 wrong threads by chance (or bad OS) then the test would fail.
2681 Made less flaky by increasing number of retries.
2682 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
2683 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
2684 Which includes the ldns_dname_absolute fix.
2685 - fwd_three test remains flaky now that unbound does not stop
2686 listening when full. Thus, removed timeout problem.
2687 It may be serviced by three threads, or maybe by one.
2688 Mostly only useful for lock-check testing now.
2690 13 October 2008: Wouter
2691 - fixed recursion servers deployed as authoritative detection, so
2692 that as a last resort, a +RD query is sent there to get the
2694 - iana port list update.
2695 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
2697 10 October 2008: Wouter
2698 - fixup tests - the negative cache contained the correct NSEC3s for
2699 two tests that are supposed to fail to validate.
2701 9 October 2008: Wouter
2702 - negative cache caps max iterations of NSEC3 done.
2703 - NSEC3 negative cache for qtype DS works.
2705 8 October 2008: Wouter
2706 - NSEC negative cache for DS.
2708 6 October 2008: Wouter
2709 - jostle-timeout option, so you can config for slow links.
2710 - 0x20 fallback code. Tries 3xnumber of nameserver addresses
2711 queries that must all be the same. Sent to random nameservers.
2712 - documented choices for DoS, EDNS, 0x20.
2714 2 October 2008: Wouter
2715 - fixup unlink of pidfile.
2716 - fixup SHA256 algorithm collation code.
2717 - contrib/update-anchor.sh does not overwrite anchors if not needed.
2718 exits 0 when a restart is needed, other values if not.
2719 so, update-anchor.sh -d mydir && /etc/rc.d/unbound restart
2720 can restart unbound exactly when needed.
2722 30 September 2008: Wouter
2723 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
2724 - tests for sha256 support and downgrade resistance.
2725 - RSASHA256 and RSASHA512 support (using the draft in dnsext),
2726 using the drafted protocol numbers.
2727 - when using stub on localhost (127.0.0.1@10053) unbound works.
2728 Like when running NSD to host a local zone, on the same machine.
2729 The noprime feature. manpages more explanation. Added a test for it.
2730 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
2732 29 September 2008: Wouter
2733 - EDNS lameness detection, if EDNS packets are dropped this is
2734 detected, eventually.
2735 - multiple query timeout rtt backoff does not backoff too much.
2737 26 September 2008: Wouter
2738 - tests for remote-control.
2739 - small memory leak in exception during remote control fixed.
2740 - fixup for lock checking but not unchecking in remote control.
2741 - iana portlist updated.
2743 23 September 2008: Wouter
2744 - Msg cache is loaded. A cache load enables cache responses.
2745 - unbound-control flush [name], flush_type and flush_zone.
2747 22 September 2008: Wouter
2748 - dump_cache and load_cache statements in unbound-control.
2749 RRsets are dumped and loaded correctly.
2750 Msg cache is dumped.
2752 19 September 2008: Wouter
2753 - locking on the localdata structure.
2754 - add and remove local zone and data with unbound-control.
2755 - ldns trunk snapshot updated, make tests work again.
2757 18 September 2008: Wouter
2758 - fixup error in time calculation.
2759 - munin plugin improvements.
2760 - nicer abbreviations for high query types values (ixfr, axfr, any...)
2761 - documented the statistics output in unbound-control man page.
2762 - extended statistics prints out histogram, over unbound-control.
2764 17 September 2008: Wouter
2765 - locking for threadsafe bogus rrset counter.
2766 - ldns trunk no longer exports b32 functions, provide compat.
2767 - ldns tarball updated.
2768 - testcode/ldns-testpkts.c const fixups.
2769 - fixed rcode stat printout.
2770 - munin plugin in contrib.
2771 - stats always printout uptime, because stats plugins need it.
2773 16 September 2008: Wouter
2774 - extended-statistics: yesno config option.
2775 - unwanted replies spoof nearmiss detector.
2776 - iana portlist updated.
2778 15 September 2008: Wouter
2779 - working start, stop, reload commands for unbound-control.
2780 - test for unbound-control working; better exit value for control.
2781 - verbosity control via unbound-control.

2814 - do not mark unsigned additionals bogus, leave unchecked, which
2817 1 September 2008: Wouter
2818 - disallow nonrecursive queries for cache snooping by default.
2819 You can allow is using access-control: <subnet> allow_snoop.

2830 again. (from bugfix#199).
2831 Some errors are not written to logfile (pidfile writing, forking),
2832 and these are only visible by using the -d commandline flag.
2834 27 August 2008: Wouter
2835 - daemon(3) is causing problems for people. Reverting the patch.
2836 bug#200, and 199 and 203 contain sideline discussion on it.

2896 11 August 2008: Wouter
2897 - Fixup rrset security updates overwriting 2181 trust status.
2898 This makes validated to be insecure data just as worthless as
2899 nonvalidated data, and 2181 rules prevent cache overwrites to them.

2997 - skip tests that need signals when testing on mingw.
2999 18 June 2008: Wouter
3000 - open testbound replay files in binary mode, because fseek/ftell
3001 do not work in ascii-mode on windows. The b does nothing on unix.
3002 unittest and testbound tests work on windows (xp too).
3003 - ioctlsocket prints nicer error message.
3004 - fixed up some TCP porting for winsock.
3005 - lack of IPv6 gives a warning, no fatal error.
3006 - use WSAGetLastError() on windows instead of errno for some errors.
3008 17 June 2008: Wouter
3009 - outgoing num fds 32 by default on windows ; it supports less
3010 fds for waiting on than unixes.
3011 - winsock_event minievent handler for windows. (you could also
3012 attempt to link with libevent/libev ports for windows).
3013 - neater crypto check and gdi32 detection.

3072 - bug 185: --disable-shared not passed along to ldns included with
3073 unbound. Fixed so that configure parameters are passed to the
3074 subdir configure script.
3075 fixed that ./libtool is used always, you can still override
3076 manually with ./configure libtool=mylibtool or set $libtool in
3078 - update of the ldns tarball to current ldns svn version (fix 181).

3178 - and check first sig byte for the encoding type.
3180 11 April 2008: Wouter
3181 - random port selection out of the configged ports.
3182 - fixup threadsafety for libevent-1.4.3+ (event_base_get_method).

3190 - automatic iana ports update from makefile. 60058 available.
3192 9 April 2008: Wouter
3193 - configure can detect libev(from its build directory) when passed
3194 --with-libevent=/home/wouter/libev-3.2
3195 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
3196 - unused commpoints not listed in epoll list.
3197 - statistics-cumulative option so that the values are not reset.
3198 - config creates array of available ports, 61841 available,
3199 it excludes <1024 and iana assigned numbers.
3200 config statements to modify the available port numbers.
3202 8 April 2008: Wouter
3203 - unbound tries to set the ulimit fds when started as server.
3204 if that does not work, it will scale back its requirements.
3206 27 March 2008: Wouter
3207 - documented /dev/random symlink from chrootdir as FAQ entry.
3209 26 March 2008: Wouter
3210 - implemented AD bit signaling. If a query sets AD bit (but not DO)
3211 then the AD bit is set in the reply if the answer validated.
3212 Without including DNSSEC signatures. Useful if you have a trusted
3213 path from the client to the resolver. Follows dnssec-updates draft.
3215 25 March 2008: Wouter
3216 - implemented check that for NXDOMAIN and NOERROR answers a query
3217 section must be present in the reply (by the scrubber). And it must
3218 be equal to the question sent, at least lowercase folded.
3219 Previously this feature happened because the cache code refused
3220 to store such messages. However blocking by the scrubber makes
3221 sure nothing gets into the RRset cache. Also, this looks like a
3222 timeout (instead of an allocation failure) and this retries are
3223 done (which is useful in a spoofing situation).
3224 - RTT banding. Band size 400 msec, this makes band around zero (fast)
3225 include unknown servers. This makes unbound explore unknown servers.
3227 7 March 2008: Wouter
3228 - -C config feature for harvest program.
3229 - harvest handles CNAMEs too.
3231 5 March 2008: Wouter
3232 - patch from Hugo Koji Kobayashi for iterator logs spelling.
3234 4 March 2008: Wouter
3235 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
3236 of a cname trust chain is lower; not full answer_AA.
3237 - test for this fix.
3238 - default config file location is /usr/local/etc/unbound.
3239 Thus prefix is used to determine the location. This is also the
3240 chroot and pidfile default location.
3242 3 March 2008: Wouter
3243 - Create 0.10 svn tag.
3244 - 0.11 version in trunk.
3245 - indentation nicer.
3247 29 February 2008: Wouter
3248 - documentation update.
3249 - fixup port to Solaris of perf test tool.
3250 - updated ldns-tarball with decl-after-statement fixes.

3254 - libunbound returns the answer packet in full.
3255 - snprintf compat update.
3256 - harvest performs lookup.
3257 - ldns-tarball update with fix for ldns_dname_label.
3258 - installs to sbin by default.
3259 - install all manual pages (unbound-host and libunbound too).
3261 27 February 2008: Wouter
3262 - option to use caps for id randomness.
3263 - config file option use-caps-for-id: yes
3264 - harvest debug tool
3266 26 February 2008: Wouter
3267 - delay utility delays TCP as well. If the server that is forwarded
3268 to has a TCP error, the delay utility closes the connection.
3269 - delay does REUSE_ADDR, and can handle a server that closes its end.
3270 - answers use casing from query.
3272 25 February 2008: Wouter
3273 - delay utility works. Gets decent thoughput too (>20000).
3275 22 February 2008: Wouter
3276 - +2% for recursions, if identical queries (except for destination
3277 and query ID) in the reply list, avoid re-encoding the answer.
3278 - removed TODO items for optimizations that do not show up in
3280 - default is now minievent - not libevent. As its faster and
3281 not needed for regular installs, only for very large port ranges.
3282 - loop check different speedup pkt-dname-reading, 1% faster for
3283 nocache-recursion check.
3284 - less hashing during msg parse, 4% for recursion.
3285 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
3286 - some speed results noted:
3287 optimization resulted in +40% for recursion (cache miss) and
3288 +70 to +80 for cache hits, and +96% for version.bind.
3289 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
3290 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
3291 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
3292 So, unbound can be about equal qps to NSD in cache hits.
3293 And about 3.4x faster than BIND in cache performance.
3294 - delay utility for testing.
3296 21 February 2008: Wouter
3297 - speedup of root-delegation message encoding by 15%.
3298 - minor speedup of compress tree_lookup, maybe 1%.
3299 - speedup of dname_lab_cmp and memlowercmp - the top functions in
3300 profiler output, maybe a couple percent when it matters.
3302 20 February 2008: Wouter
3303 - setup speec_cache for need-ldns-testns in dotests.
3304 - check number of queued replies on incoming queries to avoid overload
3306 - fptr whitelist checks are not disabled in optimize mode.
3307 - do-daemonize config file option.
3308 - minievent time share initializes time at start.
3309 - updated testdata for nsec3 new algorithm numbers (6, 7).
3310 - small performance test of packet encoding (root delegation).
3312 19 February 2008: Wouter
3313 - applied patch to unbound-host man page from Jan-Piet Mens.
3314 - fix donotquery-localhost: yes default (it erroneously was switched
3316 - time is only gotten once and the value is shared across unbound.
3317 - unittest cleans up crypto, so that it has no memory leaks.
3318 - mini_event shares the time value with unbound this results in
3319 +3% speed for cache responses and +9% for recursions.
3320 - ldns tarball update with new NSEC3 sign code numbers.
3321 - perform several reads per UDP operation. This improves performance
3322 in DoS conditions, and costs very little in normal conditions.
3323 improves cache response +50%, and recursions +10%.
3324 - modified asynclook test. because the callback from async is not
3325 in any sort of lock (and thus can use all library functions freely),
3326 this causes a tiny race condition window when the last lock is
3327 released for a callback and a new cancel() for that callback.
3328 The only way to remove this is by putting callbacks into some
3329 lock window. I'd rather have the small possibility of a callback
3330 for a cancelled function then no use of library functions in
3331 callbacks. Could be possible to only outlaw process(), wait(),
3332 cancel() from callbacks, by adding another lock, but I'd rather not.
3334 18 February 2008: Wouter
3335 - patch to unbound-host from Jan-Piet Mens.
3336 - unbound host prints errors if fails to configure context.
3337 - fixup perf to resend faster, so that long waiting requests do
3338 not hold up the queue, they become lost packets or SERVFAILs,
3339 or can be sent a little while later (i.e. processing time may
3340 take long, but throughput has to be high).
3341 - fixup iterator operating in no cache conditions (RD flag unset
3343 - streamlined code for RD flag setting.
3344 - profiled code and changed dname compares to be faster.
3345 The speedup is about +3% to +8% (depending on the test).
3346 - minievent tests for eintr and eagain.

3410 31 January 2008: Wouter
3411 - bg thread/process reads and writes the pipe nonblocking all the time
3412 so that even if the pipe is buffered or so, the bg thread does not
3413 block, and services both pipes and queries.
3415 30 January 2008: Wouter
3416 - check trailing / on chrootdir in checkconf.
3417 - check if root hints and anchor files are in chrootdir.

3449 - rewrote _wait() routine, so that it is threadsafe.
3450 - cancelation is threadsafe.
3451 - asynclook extended test in tpkg.
3452 - fixed two races where forked bg process waits for (somehow shared?)
3453 locks, so does not service the query pipe on the bg side.

3468 - libunbound QUIT setup, remove memory leaks, when using threads
3469 will share memory for passing results instead of writing it over
3470 the pipe, only writes ID number over the pipe (towards the handler
3471 thread that does process() ).
3473 22 January 2008: Wouter
3474 - library code for async in libunbound/unbound.c.
3475 - fix link testbound.
3476 - fixup exit bug in mini_event.

3485 - touch up of manpage for libunbound.
3486 - support for IP_RECVDSTADDR (for *BSD ip4).

3501 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
3503 16 January 2008: Wouter
3504 - incoming queries to the server with TC bit on are replied FORMERR.
3505 - interface-automatic replied the wrong source address on localhost
3506 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
3507 to use ifnum=-1 to mean 'no interface, use kernel route'.
3509 15 January 2008: Wouter
3510 - interface-automatic feature. experimental. Nice for anycast.
3511 - tpkg test for ip6 ancillary data.
3512 - removed debug prints.
3513 - porting experience, define for Solaris, test refined for BSD
3514 compatibility. The feature probably will not work on OpenBSD.
3515 - makedist fixup for ldns-src in build-dir.
3517 14 January 2008: Wouter
3518 - in no debug sets NDEBUG to remove asserts.

3545 - print median and quartiles with extensive logging.
3547 4 January 2008: Wouter
3548 - document misconfiguration in private network.

3551 - fixup typo in requirements.
3552 - document that 'refused' is a better choice than 'drop' for
3553 the access control list, as refused will stop retries.
3555 7 December 2007: Wouter
3556 - unbound-host has a -d option to show what happens. This can help
3557 with debugging (why do I get this answer).
3558 - fixup CNAME handling, on nodata, sets and display canonname.
3559 - dot removed from CNAME display.
3560 - respect -v for NXDOMAINs.
3561 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
3562 - size_t to int for portability of the header file.
3563 - fixup bogus handling.
3564 - dependencies and lint for unbound-host.
3566 6 December 2007: Wouter
3567 - library resolution works in foreground mode, unbound-host app
3569 - unbound-host prints rdata using ldns.
3570 - unbound-host accepts trust anchors, and prints validation
3571 information when you give -v.
3573 5 December 2007: Wouter
3574 - locking in context_new() inside the function.
3575 - setup of libworker.
3577 4 December 2007: Wouter
3578 - minor Makefile fixup.
3579 - moved module-stack code out of daemon/daemon into services/modstack,
3580 preparing for code-reuse.

3582 - context query structure.
3583 - removed unused variable pwd from checkconf.
3584 - removed unused assignment from outside netw.

3589 - fixup memleak on packet parse error.
3590 - put ; after union in parser.y.
3591 - small hardening in iter_operate against iq==NULL.
3592 - hardening, if error reply with rcode=0 (noerror) send servfail.
3593 - fixup same (*var) error in find_rrset in msgparse, was harmless.
3594 - check return value of evtimer_add().
3595 - fixup lockorder in lruhash_reclaim(), building up a list of locked
3596 entries one at a time. Instead they are removed and unlocked.
3597 - fptr_wlist for markdelfunc.
3598 - removed is_locked param from lruhash delkeyfunc.
3599 - moved bin_unlock during bin_split purely to please.
3601 3 December 2007: Wouter
3602 - changed checkconf/ to smallapp/ to make room for more support tools.
3603 (such as unbound-host).
3604 - install dirs created with -m 755 because they need to be accessible.
3605 - library extensive featurelist added to TODO.
3606 - please doxygen, lint.
3607 - library test application, with basic functionality.
3608 - fix for building in a subdirectory.
3609 - link lib fix for Leopard.
3611 30 November 2007: Wouter
3612 - makefile that creates libunbound.la, basic file or libunbound.a
3613 when creating static executables (no libtool).
3616 29 November 2007: Wouter
3617 - 0.9 public API start.
3619 28 November 2007: Wouter
3620 - Changeup plan for 0.8 - no complication needed, a simple solution
3621 has been chosen for authoritative features.
3622 - you can use single quotes in the config file, so it is possible
3623 to specify TXT records in local data.
3624 - fixup small memory problem in implicit transparent zone creation.
3625 - test for implicit zone creation and multiple RR RRsets local data.
3626 - local-zone nodefault test.
3627 - show testbound testlist on commit.
3628 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
3629 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
3631 - nicer verbosity: 0 and 1 levels.
3632 - lower nonRDquery chance of eliciting wrongly typed validation
3633 requiring message from the cache.
3634 - fix for nonRDquery validation typing; nodata is detected when
3635 SOA record in auth section (all validation-requiring nodata messages
3636 have a SOA record in authority, so this is OK for the validator),
3637 and NS record is needed to be a referral.
3638 - duplicate checking when adding NSECs for a CNAME, and test.
3639 - created svn tag 0.8, after completing testbed tests.
3641 27 November 2007: Wouter
3642 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
3643 - set size of msgparse lookup table to 32, from 1024, so that its size
3644 is below the 2048 regional large size threshold, and does not cause
3645 a call to malloc when a message is parsed.
3646 - update of memstats tool to print number of allocation calls.
3647 This is what is taking time (not space) and indicates the avg size
3648 of the allocations as well. region_alloc stat is removed.
3650 22 November 2007: Wouter
3651 - noted EDNS in-the-middle dropping trouble as a TODO.
3652 At this point theoretical, no user trouble has been reported.
3653 - added all default AS112 zones.
3654 - answers from local zone content.
3655 * positive answer, the rrset in question
3656 * nodata answer (exist, but not that type).
3657 * nxdomain answer (domain does not exist).
3658 * empty-nonterminal answer.
3659 * But not: wildcard, nsec, referral, rrsig, cname/dname,
3660 or additional section processing, NS put in auth.
3661 - test for correct working of static and transparent and couple
3662 of important defaults (localhost, as112, reverses).
3663 Also checks deny and refuse settings.
3664 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
3666 21 November 2007: Wouter
3667 - local zone internal data setup.
3669 20 November 2007: Wouter
3670 - 0.8 - str2list config support for double string config options.
3671 - local-zone and local-data options, config storage and documentation.
3673 19 November 2007: Wouter
3674 - do not downcase NSEC and RRSIG for verification. Follows
3675 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
3676 - fixup leaking unbound daemons at end of tests.
3677 - README file updated.
3678 - nice libevent not found error.
3679 - README talks about gnu make.
3680 - 0.8: unit test for addr_mask and fixups for it.
3681 and unit test for addr_in_common().
3682 - 0.8: access-control config file element.
3683 and unit test rpl replay file.
3684 - 0.8: fixup address reporting from netevent.
3686 16 November 2007: Wouter
3687 - privilege separation is not needed in unbound at this time.
3688 TODO item marked as such.
3689 - created beta-0.7 branch for support.
3690 - tagged 0.7 for beta release.
3691 - moved trunk to 0.8 for 0.8(auth features) development.
3692 - 0.8: access control list setup.
3694 15 November 2007: Wouter
3695 - review fixups from Jelte.
3697 14 November 2007: Wouter
3698 - testbed script does not recreate configure, since its in svn now.
3699 - fixup checkconf test so that it does not test
3700 /etc/unbound/unbound.conf.
3703 13 November 2007: Wouter
3704 - remove debug print.
3705 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
3707 12 November 2007: Wouter
3708 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
3710 - bugreports to unbound-bugs@nlnetlabs.nl
3711 - fixup testbound so it exits cleanly.
3712 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
3714 9 November 2007: Wouter
3715 - took ldns snapshot in repo.
3716 - default config file is /etc/unbound/unbound.conf.
3717 If it doesn't exist, it is installed with the doc/example.conf file.
3718 The file is not deleted on uninstall.
3719 - default listening is not all, but localhost interfaces.
3721 8 November 2007: Wouter
3722 - Fixup chroot and drop user privileges.
3723 - new L root ip address in default hints.
3725 1 November 2007: Wouter
3726 - Fixup of crash on reload, due to anchors in env not NULLed after
3727 dealloc during deinit.
3728 - Fixup of chroot call. Happens after privileges are dropped, so
3729 that checking the passwd entry still works.
3730 - minor touch up of clear() hashtable function.
3731 - VERB_DETAIL prints out what chdir, username, chroot is being done.
3732 - when id numbers run out, caches are cleared, as in design notes.
3733 Tested with a mock setup with very few bits in id, it worked.
3734 - harden-dnssec-stripped: yes is now default. It insists on dnssec
3735 data for trust anchors. Included tests for the feature.
3737 31 October 2007: Wouter
3738 - cache-max-ttl config option.
3739 - building outside sourcedir works again.
3740 - defaults more secure:
3742 chroot: "/etc/unbound"
3743 The operator can override them to be less secure ("") if necessary.
3744 - fix horrible oversight in sorting rrset references in a message,
3745 sort per reference key pointer, not on referencepointer itself.
3746 - pidfile: "/etc/unbound/unbound.pid" is now the default.
3747 - tests changed to reflect the updated default.
3748 - created hashtable clear() function that respects locks.
3750 30 October 2007: Wouter
3751 - fixup assertion failure that relied on compressed names to be
3752 smaller than uncompressed names. A packet from comrite.com was seen
3753 to be compressed to a larger size. Added it as unit test.
3754 - quieter logging at low verbosity level for common tcp messages.
3755 - no greedy TTL update.
3757 23 October 2007: Wouter
3758 - fixup (grand-)parent problem for dnssec-lameness detection.
3759 - fixup tests to do additional section processing for lame replies,
3760 since the detection needs that.
3761 - no longer trust in query section in reply during dnssec lame detect.
3762 - dnssec lameness does not make the server never ever queried, but
3763 non-preferred. If no other servers exist or answer, the dnssec lame
3764 server is used; the fastest dnssec lame server is chosen.
3765 - added test then when trust anchor cannot be primed (nodata), the
3766 insecure mode from unbound works.
3767 - Fixup max queries per thread, any more are dropped.
3769 22 October 2007: Wouter
3770 - added donotquerylocalhost config option. Can be turned off for
3772 - ISO C compat changes.
3773 - detect RA-no-AA lameness, as LAME.
3774 - DNSSEC-lameness detection, as LAME.
3775 See notes in requirements.txt for choices made.
3776 - tests for lameness detection.
3777 - added all to make test target; need unbound for fwd tests.
3778 - testbound does not pollute /etc/unbound.
3780 19 October 2007: Wouter
3781 - added configure (and its files) to svn, so that the trunk is easier
3782 to use. ./configure, config.guess, config.sub, ltmain.sh,
3784 - added yacc/lex generated files, util/configlexer.c,
3785 util/configparser.c util/configparser.h, to svn.
3786 - without lex no attempt to use it.
3787 - unsecure response validation collated into one block.
3788 - remove warning about const cast of cfgfile name.
3789 - outgoing-interfaces can be different from service interfaces.
3790 - ldns-src configure is done during unbound configure and
3791 ldns-src make is done during unbound make, and so inherits the
3792 make arguments from the unbound make invocation.
3793 - nicer error when libevent problem causes instant exit on signal.
3794 - read root hints from a root hint file (like BIND does).
3796 18 October 2007: Wouter
3797 - addresses are logged with errors.
3798 - fixup testcode fake event to remove pending before callback
3799 since the callback may create new pending items.
3800 - tests updated because retries are now in iterator module.
3801 - ldns-testpkts code is checked for differences between unbound
3802 and ldns by makedist.sh.
3803 - ldns trunk from today added in svn repo for fallback in case
3804 no ldns is installed on the system.
3805 make download_ldns refreshes the tarball with ldns svn trunk.
3806 - ldns-src.tar.gz is used if no ldns is found on the system, and
3807 statically linked into unbound.
3808 - start of regional allocator code.
3809 - regional uses less memory and variables, simplified code.
3810 - remove of region-allocator.
3811 - alloc cache keeps a cache of recently released regional blocks,
3813 - make unit test cleanly free memory.
3815 17 October 2007: Wouter
3816 - fixup another cycle detect and ns-addr timeout resolution bug.
3817 This time by refusing delegations from the cache without addresses
3818 when resolving a mandatory-glue nameserver-address for that zone.
3819 We're going to have to ask a TLD server anyway; might as well be
3820 the TLD server for this name. And this resolves a lot of cases where
3821 the other nameserver names lead to cycles or are not available.
3822 - changed random generator from random(3) clone to arc4random wrapped
3823 for thread safety. The random generator is initialised with
3824 entropy from the system.
3825 - fix crash where failure to prime DNSKEY tried to print null pointer
3827 - removed some debug prints, only verb_algo (4) enables them.
3828 - fixup test; new random generator took new paths; such as one
3829 where no scripted answer was available.
3830 - mark insecure RRs as insecure.
3831 - fixup removal of nonsecure items from the additional.
3832 - reduced timeout values to more realistic, 376 msec (262 msec has
3833 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
3834 - server selection failover to next server after timeout (376 msec).
3836 16 October 2007: Wouter
3837 - no malloc in log_hex.
3838 - assertions around system calls.
3839 - protect against gethostname without ending zero.
3840 - ntop output is null terminated by unbound.
3841 - pidfile content null termination
3842 - various snprintf use sizeof(stringbuf) instead of fixed constant.
3843 - changed loopdetect % 8 with & 0x7 since % can become negative for
3844 weird negative input and particular interpretation of integer math.
3845 - dname_pkt_copy checks length of result, to protect result buffers.
3846 prints an error, this should not happen. Bad strings should have
3847 been rejected earlier in the program.
3848 - remove a size_t underflow from msgreply size func.
3850 15 October 2007: Wouter
3852 - fix IP6 TCP, wrong definition check. With test package.
3853 - fixup the fact that the query section was not compressed to,
3854 the code was there but was called by value instead of by reference.
3855 And test for the case, uses xxd and nc.
3856 - more portable ip6 check for sockaddr types.
3858 8 October 2007: Wouter
3859 - --disable-rpath option in configure for 64bit systems with
3860 several dynamic lib dirs.
3862 7 October 2007: Wouter
3863 - fixup tests for no AD bit in non-DO queries.
3864 - test that makes sure AD bit is not set on non-DO query.
3866 6 October 2007: Wouter
3867 - removed logfile open early. It did not have the proper permissions;
3868 it was opened as root instead of the user. And we cannot change user
3869 id yet, since chroot and bind ports need to be done.
3870 - callback checks for event callbacks done from mini_event. Because
3871 of deletions cannot do this from netevent. This means when using
3872 libevent the protection does not work on event-callbacks.
3873 - fixup too small reply (did not zero counts).
3874 - fixup reply no longer AD bit when query without DO bit.
3876 5 October 2007: Wouter
3877 - function pointer whitelist.
3879 4 October 2007: Wouter
3880 - overwrite sensitive random seed value after use.
3881 - switch to logfile very soon if not -d (console attached).
3882 - error messages do not reveal the trustanchor contents.
3883 - start work on function pointer whitelists.
3885 3 October 2007: Wouter
3886 - fix for multiple empty nonterminals, after multiple DSes in the
3888 - mesh checks if modules are looping, and stops them.
3889 - refetch with CNAMEd nameserver address regression test added.
3890 - fixup line count bug in testcode, so testbound prints correct line
3891 number with parse errors.
3892 - unit test for multiple ENT case.
3893 - fix for cname out of validated unsec zone.
3894 - fixup nasty id=0 reuse. Also added assertions to detect its
3895 return (the assertion catches in the existing test cases).
3897 1 October 2007: Wouter
3898 - skip F77, CXX, objC tests in configure step.
3899 - fixup crash in refetch glue after a CNAME.
3900 and protection against similar failures (with error print).
3902 28 September 2007: Wouter
3903 - test case for unbound-checkconf, fixed so it also checks the
3904 interface: statements.
3906 26 September 2007: Wouter
3907 - SIGHUP will reopen the log file.
3908 - Option to log to syslog.
3909 - please lint, fixup tests (that went to syslog on open, oops).
3910 - config check program.
3912 25 September 2007: Wouter
3913 - tests for NSEC3. Fixup bitmap checks for NSEC3.
3914 - positive ANY response needs to check if wildcard expansion, and
3915 check that original data did not exist.
3916 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
3917 delegation, for abuse of child zone apex nsec3.
3918 - create 0.5 release tag.
3920 24 September 2007: Wouter
3921 - do not make test programs by default.
3922 - But 'make test' will perform all of the tests.
3923 - Advertise builtin select libevent alternative when no libevent
3925 - signit can generate NSEC3 hashes, for generating tests.
3926 - multiple nsec3 paramaters in message test.
3927 - too high nsec3 iterations becomes insecure test.
3929 21 September 2007: Wouter
3930 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
3931 - fixup testcode lock safety (port FreeBSD).
3932 - removes subscript has type char warnings (port Solaris 9).
3933 - fixup of field with format type to int (port MacOS/X intel).
3934 - added test for infinite loop case in nonRD answer validation.
3935 It was a more general problem, but hard to reproduce. When an
3936 unsigned rrset is being validated and the key fetched, the DS
3937 sequence is followed, but if the final name has no DS, then no
3938 proof is possible - the signature has been stripped off.
3940 20 September 2007: Wouter
3941 - fixup and test for NSEC wildcard with empty nonterminals.
3942 - makedist.sh fixup for svn info.
3943 - acl features request in plan.
3944 - improved DS empty nonterminal handling.
3945 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
3946 proof anyway, which succeeds in ANS failure case.
3947 - striplab protection in case it becomes -1.
3948 - plans for static and blacklist config.
3950 19 September 2007: Wouter
3951 - comments about non-packed usage.
3952 - plan for overload support in 0.6.
3953 - added testbound tests for a failed resolution from the logs
3954 and for failed prime when missing glue.
3955 - fixup so useless delegation points are not returned from the
3956 cache. Also the safety belt is used if priming fails to complete.
3957 - fixup NSEC rdata not to be lowercased, bind compat.
3959 18 September 2007: Wouter
3960 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
3961 - validator prints subtype classification for debug.
3963 17 September 2007: Wouter
3964 - NSEC3 hash cache unit test.
3965 - validator nsec3 nameerror test.
3967 14 September 2007: Wouter
3968 - nsec3 nodata proof, nods proof, wildcard proof.
3969 - nsec3 support for cname chain ending in noerror or nodata.
3970 - validator calls nsec3 proof routines if no NSECs prove anything.
3971 - fixup iterator bug where it stored the answer to a cname under
3972 the wrong qname into the cache. When prepending the cnames, the
3973 qname has to be reset to the original qname.
3975 13 September 2007: Wouter
3976 - nsec3 find matching and covering, ce proof, prove namerror msg.
3978 12 September 2007: Wouter
3979 - fixup of manual page warnings, like for NSD bugreport.
3980 - nsec3 work, config, max iterations, filter, and hash cache.
3982 6 September 2007: Wouter
3983 - fixup to find libevent on mac port install.
3984 - fixup size_t vs unsigned portability in validator/sigcrypt.
3985 - please compiler on different platforms, for unreachable code.
3987 - pthread_rwlock type is optional, in case of old pthread libs.
3989 5 September 2007: Wouter
3990 - cname, name error validator tests.
3991 - logging of qtype ANY works.
3992 - ANY type answers get RRSIG in answer section of replies (but not
3993 in other sections, unless DO bit is on).
3994 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
3995 - DS and noDS referral validation test.
3996 - if you configure many trust anchors, parent trust anchors can
3997 securely deny existance of child trust anchors, if validated.
3998 - not all *.name NSECs are present because a wildcard was matched,
3999 and *.name NSECs can prove nodata for empty nonterminals.
4000 Also, for wildcard name NSECs, check they are not from the parent
4001 zone (for wildcarded zone cuts), and check absence of CNAME bit,
4003 - configure option for memory allocation debugging.
4004 - port configure option for memory allocation to solaris10.
4006 4 September 2007: Wouter
4007 - fixup of Leakage warning when serviced queries processed multiple
4008 callbacks for the same query from the same server.
4009 - testbound removes config file from /tmp on failed exit.
4010 - fixup for referral cleanup of the additional section.
4011 - tests for cname, referral validation.
4012 - neater testbound tpkg output.
4013 - DNAMEs no longer match their apex when synthesized from the cache.
4014 - find correct signer name for DNAME responses.
4015 - wildcarded DNAME test and fixup code to detect.
4016 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
4017 So that wildcarded CNAMEs get their NSEC with them to the answer.
4018 - test for a CNAME to a DNAME to a CNAME to an answer, all from
4019 different domains, for key fetching and signature checking of
4022 3 September 2007: Wouter
4023 - Fixed error in iterator that would cause assertion failure in
4024 validator. CNAME to a NXDOMAIN response was collated into a response
4025 with both a CNAME and the NXDOMAIN rcode. Added a test that the
4026 rcode is changed to NOERROR (because of the CNAME).
4027 - timeout on tcp does not lead to spurious leakage detect.
4028 - account memory for name of lame zones, so that memory leakages does
4029 not show lame cache growth as a leakage growth.
4030 - config setting for lameness cache expressed in bytes, instead of
4032 - tool too summarize allocations per code line.
4034 31 August 2007: Wouter
4035 - can read bind trusted-keys { ... }; files, in a compatibility mode.
4036 - iterator should not detach target queries that it still could need.
4037 the protection against multiple outstanding queries is moved to a
4038 current_query num check.
4039 - validator nodata, positive, referral tests.
4040 - dname print can print '*' wildcard.
4042 30 August 2007: Wouter
4043 - fixup override date config option.
4044 - config options to control memory usage.
4045 - caught bad free of un-alloced data in worker_send error case.
4046 - memory accounting for key cache (trust anchors and temporary cache).
4047 - memory accounting fixup for outside network tcp pending waits.
4048 - memory accounting fixup for outside network tcp callbacks.
4049 - memory accounting for iterator fixed storage.
4050 - key cache size and slabs config options.
4051 - lib crypto cleanups at exit.
4053 29 August 2007: Wouter
4054 - test tool to sign rrsets for testing validator with.
4055 - added RSA and DSA test keys, public and private pairs, 512 bits.
4056 - default configuration is with validation enabled.
4057 Only a trust-anchor needs to be configured for DNSSEC to work.
4058 - do not convert to DER for DSA signature verification.
4059 - validator replay test file, for a DS to DNSKEY DSA key prime and
4062 28 August 2007: Wouter
4063 - removed double use for udp buffers, that could fail,
4064 instead performs a malloc to do the backup.
4065 - validator validates referral messages, by validating all the rrsets
4066 and stores the rrsets in the cache. Further referral (nonRD queries)
4067 replies are made from the rrset cache directly. Unless unchecked
4068 rrsets are encountered, there are then validated.
4069 - enforce that signing is done by a parent domain (or same domain).
4070 - adjust TTL downwards if rrset TTL bigger than signature allows.
4071 - permissive mode feature, sets AD bit for secure, but bogus does
4072 not give servfail (bogus is changed into indeterminate).
4073 - optimization of rrset verification. rr canonical sorting is reused,
4074 for the same rrset. canonical rrset image in buffer is reused for
4076 - if the rrset is too big (64k exactly + large owner name) the
4077 canonicalization routine will fail if it does not fit in buffer.
4078 - faster verification for large sigsets.
4079 - verb_detail mode reports validation failures, but not the entire
4080 algorithm for validation. Key prime failures are reported as
4083 27 August 2007: Wouter
4084 - do not garble the edns if a cache answer fails.
4085 - answer norecursive from cache if possible.
4086 - honor clean_additional setting when returning secure non-recursive
4088 - do not store referral in msg cache for nonRD queries.
4089 - store verification status in the rrset cache to speed up future
4091 - mark rrsets indeterminate and insecure if they are found to be so.
4092 and store this in the cache.
4094 24 August 2007: Wouter
4095 - message is bogus if unsecure authority rrsets are present.
4096 - val-clean-additional option, so you can turn it off.
4097 - move rrset verification out of the specific proof types into one
4098 routine. This makes the proof routines prettier.
4099 - fixup cname handling in validator, cname-to-positive and cname-to-
4101 - Do not synthesize DNSKEY and DS responses from the rrset cache if
4102 the rrset is from the additional section. Signatures may have
4103 fallen off the packet, and cause validation failure.
4104 - more verbose signature date errors (with the date attached).
4105 - increased default infrastructure cache size. It is important for
4106 performance, and 1000 entries are only 212k (or a 400 k total cache
4107 size). To 10000 entries (for 2M entries, 4M cache size).
4109 23 August 2007: Wouter
4110 - CNAME handling - move needs_validation to before val_new().
4111 val_new() setups the chase-reply to be an edited copy of the msg.
4112 new classification, and find signer can find for it.
4113 removal of unsigned crap from additional, and query restart for
4115 - refuse to follow wildcarded DNAMEs when validating.
4116 But you can query for qtype ANY, or qtype DNAME and validate that.
4118 22 August 2007: Wouter
4120 - review - use val_error().
4122 21 August 2007: Wouter
4123 - ANY response validation.
4124 - store security status in cache.
4125 - check cache security status and either send the query to be
4126 validated, return the query to client, or send servfail to client.
4127 Sets AD bit on validated replies.
4128 - do not examine security status on an error reply in mesh_done.
4129 - construct DS, DNSKEY messages from rrset cache.
4130 - manual page entry for override-date.
4132 20 August 2007: Wouter
4133 - validate and positive validation, positive wildcard NSEC validation.
4134 - nodata validation, nxdomain validation.
4136 18 August 2007: Wouter
4137 - process DNSKEY response in FINDKEY state.
4139 17 August 2007: Wouter
4140 - work on DS2KE routine.
4141 - val_nsec.c for validator NSEC proofs.
4142 - unit test for NSEC bitmap reading.
4143 - dname iswild and canonical_compare with unit tests.
4145 16 August 2007: Wouter
4147 - latest release libevent 1.3c and 1.3d have threading fixed.
4148 - key entry fixup data pointer and ttl absolute.
4149 - This makes a key-prime succeed in validator, with DS or DNSKEY as
4151 - fixup canonical compare byfield routine, fix bug and also neater.
4152 - fixed iterator response type classification for queries of type
4154 dig ANY gives sometimes NS rrset in AN and NS section, and parser
4155 removes the NS section duplicate. dig NS gives sometimes the NS
4156 in the answer section, as referral.
4157 - validator FINDKEY state.
4159 15 August 2007: Wouter
4160 - crypto calls to verify signatures.
4161 - unit test for rrsig verification.
4163 14 August 2007: Wouter
4164 - default outgoing ports changed to avoid port 2049 by default.
4165 This port is widely blocked by firewalls.
4166 - count infra lameness cache in memory size.
4167 - accounting of memory improved
4168 - outbound entries are allocated in the query region they are for.
4169 - extensive debugging for memory allocations.
4170 - --enable-lock-checks can be used to enable lock checking.
4171 - protect undefs in config.h from autoheaders ministrations.
4172 - print all received udp packets. log hex will print on multiple
4174 - fixed error in parser with backwards rrsig references.
4175 - mark cycle targets for iterator did not have CD flag so failed
4178 13 August 2007: Wouter
4179 - fixup makefile, if lexer is missing give nice error and do not
4180 mess up the dependencies.
4181 - canonical compare routine updated.
4182 - canonical hinfo compare.
4183 - printout list of the queries that the mesh is working on.
4185 10 August 2007: Wouter
4186 - malloc and free overrides that track total allocation and frees.
4187 for memory debugging.
4188 - work on canonical sort.
4190 9 August 2007: Wouter
4191 - canonicalization, signature checks
4192 - dname signature label count and unit test.
4193 - added debug heap size print to memory printout.
4194 - typo fixup in worker.c
4195 - -R needed on solaris.
4196 - validator override option for date check testing.
4198 8 August 2007: Wouter
4199 - ldns _raw routines created (in ldns trunk).
4200 - sigcrypt DS digest routines
4201 - val_utils uses sigcrypt to perform signature cryptography.
4202 - sigcrypt keyset processing
4204 7 August 2007: Wouter
4205 - security status type.
4206 - security status is copied when rdata is equal for rrsets.
4207 - rrset id is updated to invalidate all the message cache entries
4208 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
4210 - val_sigcrypt file for validator signature checks.
4212 6 August 2007: Wouter
4213 - key cache for validator.
4214 - moved isroot and dellabel to own dname routines, with unit test.
4216 3 August 2007: Wouter
4218 - scrubber check section of lame NS set.
4219 - trust anchors can be in config file or read from zone file,
4220 DS and DNSKEY entries.
4221 - unit test trust anchor storage.
4222 - trust anchors converted to packed rrsets.
4223 - key entry definition.
4225 2 August 2007: Wouter
4226 - configure change for latest libevent trunk version (needs -lrt).
4227 - query_done and walk_supers are moved out of module interface.
4228 - fixup delegation point duplicates.
4229 - fixup iterator scrubber; lame NS set is let through the scrubber
4230 so that the classification is lame.
4231 - validator module exists, and does nothing but pass through,
4232 with calling of next module and return.
4235 1 August 2007: Wouter
4236 - set version to 0.5
4237 - module work for module to module interconnections.
4238 - config of modules.
4239 - detect cycle takes flags.
4241 31 July 2007: Wouter
4245 30 July 2007: Wouter
4246 - changed random state init, so that sequential process IDs are not
4247 cancelled out by sequential thread-ids in the random number seed.
4248 - the fwd_three test, which sends three queries to unbound, and
4249 unbound is kept waiting by ldns-testns for 3 seconds, failed
4250 because the retry timeout for default by unbound is 3 seconds too,
4251 it would hit that timeout and fail the test. Changed so that unbound
4252 is kept waiting for 2 seconds instead.
4254 27 July 2007: Wouter
4255 - removed useless -C debug option. It did not work.
4256 - text edit of documentation.
4257 - added doc/CREDITS file, referred to by the manpages.
4260 26 July 2007: Wouter
4261 - cycle detection, for query state dependencies. Will attempt to
4262 circumvent the cycle, but if no other targets available fails.
4263 - unit test for AXFR, IXFR response.
4264 - test for cycle detection.
4266 25 July 2007: Wouter
4267 - testbound read ADDRESS and check it.
4268 - test for version.bind and friends.
4269 - test for iterator chaining through several referrals.
4270 - test and fixup for refetch for glue. Refetch fails if glue
4271 is still not provided.
4273 24 July 2007: Wouter
4274 - Example section in config manual.
4275 - Addr stored for range and moment in replay.
4277 20 July 2007: Wouter
4278 - Check CNAME chain before returning cache entry with CNAMEs.
4279 - Option harden-glue, default is on. It will discard out of zone
4280 data. If disabled, performance is faster, but spoofing attempts
4281 become a possibility. Note that still normalize scrubbing is done,
4282 and that the potentially spoofed data is used for infrastructure
4283 and not returned to the client.
4284 - if glue times out, refetch by asking parent of delegation again.
4285 Much like asking for DS at the parent side.
4286 - TODO items from forgery-resilience draft.
4287 and on memory handling improvements.
4288 - renamed module_event_timeout to module_event_noreply.
4289 - memory reporting code; reports on memory usage after handling
4290 a network packet (not on cache replies).
4292 19 July 2007: Wouter
4293 - shuffle NS selection when getting nameserver target addresses.
4294 - fixup of deadlock warnings, yield cpu in checklock code so that
4295 freebsd scheduler selects correct process to run.
4296 - added identity and version config options and replies.
4297 - store cname messages complete answers.
4299 18 July 2007: Wouter
4300 - do not query addresses, 127.0.0.1, and ::1 by default.
4302 17 July 2007: Wouter
4303 - forward zone options in config file.
4304 - forward per zone in iterator. takes precendence over stubs.
4305 - fixup commithooks.
4306 - removed forward-to and forward-to-port features, subsumed by
4308 - fix parser to handle absent server: clause.
4309 - change untrusted rrset test to account for scrubber that is now
4310 applied during the test (which removes the poison, by the way).
4311 - feature, addresses can be specified with @portnumber, like nsd.conf.
4312 - test config files changed over to new forwarder syntax.
4314 27 June 2007: Wouter
4315 - delete of mesh does a postorder traverse of the tree.
4316 - found and fixed a memory leak. For TTL=0 messages, that would
4317 not be cached, instead the msg-replyinfo structure was leaked.
4318 - changed server selection so it will filter out hosts that are
4319 unresponsive. This is defined as a host with the maximum rto value.
4320 This means that unbound tried the host for retries up to 120 secs.
4321 The rto value will time out after host-ttl seconds from the cache.
4322 This keeps such unresolvable queries from taking up resources.
4323 - utility for keeping histogram.
4325 26 June 2007: Wouter
4326 - mesh is called by worker, and iterator uses it.
4327 This removes the hierarchical code.
4328 QueryTargets state and Finished state are merged for iterator.
4329 - forwarder mode no longer sets AA bit on first reply.
4330 - rcode in walk_supers is not needed.
4332 25 June 2007: Wouter
4334 - error encode routine for ease.
4336 22 June 2007: Wouter
4337 - removed unused _node iterator value from rbtree_t. Takes up space.
4338 - iterator can handle querytargets state without a delegation point
4339 set, so that a priming(stub) subquery error can be handled.
4340 - iterator stores if it is priming or not.
4341 - log_query_info() neater logging.
4342 - changed iterator so that it does not alter module_qstate.qinfo
4343 but keeps a chase query info. Also query_flags are not altered,
4344 the iterator uses chase_flags.
4345 - fixup crash in case no ports for the family exist.
4347 21 June 2007: Wouter
4348 - Fixup secondary buffer in case of error callback.
4349 - cleanup slumber list of runnable states.

4360 - set num target queries to 0 when you move them to slumber list.
4361 - typo in check caused subquery errors to be ignored, fixed.
4362 - make lint happy about rlim_t.
4363 - freeup of modules after freeup of module-states.
4364 - duplicate replies work, this uses secondary udp buffer in outnet.
4366 19 June 2007: Wouter
4367 - nicer layout in stats.c, review 0.3 change.
4368 - spelling improvement, review 0.3 change.

4382 - another offbyone in targetcounter. Also in Java prototype by the way.
4384 15 June 2007: Wouter
4385 - if a query asks to be notified of the same serviced query result
4386 multiple times, this will succeed. Only one callback will happen;
4387 multiple outbound-list entries result (but the double cleanup of it
4389 - when iterator moves on due to CNAME or referral, it will remove
4390 the subqueries (for other targets). These are put on the slumber
4392 - state module wait subq is OK with no new subqs, an old one may have
4393 stopped, with an error, and it is still waiting for other ones.
4394 - if a query loops, halt entire query (easy way to clean up properly).
4396 14 June 2007: Wouter
4397 - num query targets was > 0 , not >= 0 compared, so that fetch
4398 policy of 0 did nothing.
4400 13 June 2007: Wouter
4401 - debug option: configure --enable-static-exe for compile where
4402 ldns and libevent are linked statically. Default is off.

4416 11 June 2007: Wouter
4417 - replies on TCP queries have the address field set in replyinfo,
4418 for serviced queries, because the initiator does not know that
4419 a TCP fallback has occured.
4420 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
4421 if qtype directly queries for the type (and then only show that
4422 'unknown type' in the answer section).
4423 - fixed message parsing where rrsigs on their own would be put
4424 in the signature list over the rrsig type.

4452 - debug routine to print dns_msg as handled by iterator.
4453 - memleak in config file stubs fixup.
4454 - more small bugs, in scrubber, query compare no ID for lookup,
4455 in dname validation for NS targets.
4456 - sets entry.key for new special allocs.
4457 - lognametypeclass can display unknown types and classes.
4460 - random selection of equally preferred nameserver targets.
4461 - reply info copy routine. Reuses existing code.
4462 - cache lameness in response handling.
4463 - do not touch qstate after worker_process_query because it may have
4464 been deleted by that routine.
4465 - Prime response state.
4466 - Process target response state.
4467 - some memcmp changed to dname_compare for case preservation.
4470 - normalize incoming messages. Like unbound-java, with CNAME chain

4478 - querytargets state.
4479 - dname_subdomain_c() routine.
4480 - server selection, based on RTT. ip6 is filtered out if not available,
4481 and lameness is checked too.
4482 - delegation point copy routine.
4485 - removed FLAG_CD from message and rrset caches. This was useful for
4486 an agnostic forwarder, but not for a sophisticated (trust value per
4487 rrset enabled) cache.
4488 - iterator reponse typing.
4489 - iterator cname handle.
4490 - iterator prime start.
4492 - processInitRequest and processInitRequest2.

4507 rrset cache from module environment.
4508 - packed rrset key has type and class as easily accessable struct
4509 members. They are still kept in network format for fast msg encode.
4510 - dns cache find_delegation routine.
4511 - iterator main functions setup.
4512 - dns cache lookup setup.
4515 - small changes to prepare for subqueries.

4619 not fit, and will leave out (whole)rrsets from additional if needed.
4622 - decompress query section, extremely lenient acceptance.
4623 But only for answers from other servers, not for plain queries.
4624 - compression and decompression test cases.
4626 - example.conf interface: line is changed from 127.0.0.1 which leads
4627 to problems if used (restricting communication to the localhost),
4628 to a documentation and test address.

4703 10 April 2007: Wouter
4704 - Improved alignment of reply_info packet, nice for 32 and 64 bit.

4721 3 April 2007: Wouter
4722 - detect sign of msghdr.msg_iovlen so that the cast to that type
4723 in netevent (which is there to please lint) can be correct.

4806 - query_info and replymsg util/data structure.
4808 9 March 2007: Wouter
4809 - added rwlock writelock checking.
4810 So it will keep track of the writelock, and readlocks are enforced
4811 to not change protected memory areas.
4812 - log_hex function to dump hex strings to the logfile.
4813 - checklocks zeroes its destroyed lock after checking memory areas.
4814 - unit test for alloc.
4815 - identifier for union in checklocks to please older compilers.
4818 8 March 2007: Wouter
4819 - Reviewed checklock code.
4821 7 March 2007: Wouter
4822 - created a wrapper around thread calls that performs some basic
4823 checking for data race and deadlock, and basic performance
4824 contention measurement.
4826 6 March 2007: Wouter
4827 - Testbed works with threading (different machines, different options).
4828 - alloc work, does the special type.
4830 2 March 2007: Wouter
4831 - do not compile fork funcs unless needed. Otherwise will give
4832 type errors as their typedefs have not been enabled.
4833 - log shows thread numbers much more nicely (and portably).
4834 - even on systems with nonthreadsafe libevent signal handling,
4835 unbound will exit if given a signal.
4836 Reloads will not work, and exit is not graceful.
4837 - start of alloc framework layout.
4839 1 March 2007: Wouter
4840 - Signals, libevent and threads work well, with libevent patch and

4848 Thread_join is replaced with waitpid.
4849 - During reloads the daemon will temporarily handle signals,
4850 so that they do not result in problems.
4851 - Also randomize the outgoing port range for tests.
4852 - If query list is full, will stop selecting listening ports for read.
4853 This makes all threads service incoming requests, instead of one.
4854 No memory is leaking during reloads, service of queries, etc.
4855 - test that uses ldns-testns -f to test threading. Have to answer
4856 three queries at the same time.
4857 - with verbose=0 operates quietly.
4859 26 February 2007: Wouter
4860 - ub_random code used to select ID and port.

4864 - don't open pipes for #0, doesn't need it.
4865 - listens to SIGTERM, SIGQUIT, SIGINT (all quit) and SIGHUP (reload).
4867 23 February 2007: Wouter
4868 - Can do reloads on sigHUP. Everything is stopped, and freed,
4869 except the listening ports. Then the config file is reread.
4870 And everything is started again (and listening ports if needed).
4871 - Ports for queries are shared.
4872 - config file added interface:, chroot: and username:.
4873 - config file: directory, logfile, pidfile. And they work too.
