11 21 February 2014: Wouter
12 - iana portlist updated.
14 20 February 2014: Matthijs
15 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
16 received. This is okay according 4035, but not after revising
17 existence in 4592. NSEC empty non-terminals exist and thus the
18 RCODE should have been NOERROR. If this occurs, and the RRsets
19 are secure, we set the RCODE to NOERROR and the security status
20 of the reponse is also considered secure.
22 14 February 2014: Wouter
23 - Works on Minix (3.2.1).
25 11 February 2014: Wouter

51 - fixup nss compile (no ldns in it).
52 - fixup warning in unitldns
53 - fixup WKS and rdata type service to print unsigned because strings
54 are not portable; they cannot be read (for sure) on other computers.
55 - fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
58 30 January 2014: Wouter
59 - delay-close does not act if there are udp-wait queries, so that
60 it does not make a socketdrain DoS easier.
62 28 January 2014: Wouter
63 - iana portlist updated.
64 - iana portlist test updated so it does not touch the source
65 if there are no changes.
66 - delay-close: msec option that delays closing ports for which
67 the UDP reply has timed out. Keeps the port open, only accepts
68 the correct reply. This correct reply is not used, but the port
69 is open so that no port-denied ICMPs are generated.
71 27 January 2014: Wouter
72 - reuseport is attempted, then fallback to without on failure.
74 24 January 2014: Wouter
75 - Change unbound-event.h to use void* buffer, length idiom.
76 - iana portlist updated.
77 - unbound-event.h is installed if you configure --enable-event-api.
78 - speed up unbound (reports say it could be up to 10%), by reducing
79 lock contention on localzones.lock. It is changed to an rwlock.
80 - so-reuseport: yesno option to distribute queries evenly over
81 threads on Linux (Thanks Robert Edmonds).
84 21 January 2014: Wouter
85 - Fix #547: no trustanchor written if filesystem full, fclose checked.
87 17 January 2014: Wouter
88 - Fix isprint() portability in sldns, uses unsigned int.
89 - iana portlist updated.
91 16 January 2014: Wouter
92 - fix #544: Fixed +i causes segfault when running with module conf
94 - Windows port, adjust %lld to %I64d, and warning in win_event.c.
96 14 January 2014: Wouter
97 - iana portlist updated.
100 - Fix bug in cachedump that uses sldns.
101 - update pythonmod for ldns_ to sldns_ name change.
104 - Fix sldns to use sldns_ prefix for all ldns_ variables.

109 linking with libldns that uses global variables ldns_ .
112 - Fix bug#537: compile python plugin without ldns library.
115 - Fix bug#536: acl_deny_non_local and refuse_non_local added.

119 is called by libunbound in the mesh attach.
120 - Accept ip-address: as an alternative for interface: for
121 consistency with nsd.conf syntax.
124 - Patch from Neel Goyal to fix callback in libunbound.
127 - if configured --with-libunbound-only fix make install.
130 - Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
131 more specific interface port 53 can be used at the same time, and
132 one of the daemons is unbound.
133 - iana portlist update.
134 - separate ldns into core ldns inside ldns/ subdirectory. No more
135 --with-ldns is needed and unbound does not rely on libldns.
136 - portability fixes for new USE_SLDNS ldns subdir codebase.
139 - Patch from Neel Goyal: Add an API call to set an event base on an
140 existing ub_ctx. This basically just destroys the current worker and
141 sets the event base to the current. And fix a deadlock in
142 ub_resolve_event – the cfglock is held when libworker_create is
143 called. This ends up trying to acquire the lock again in
144 context_obtain_alloc in the call chain.
145 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
148 - unbound-event.h is installed if configured --with-libevent. It
149 contains low-level library calls, that use libevent's event_base
150 and an ldns_buffer for the wire return packet to perform async
151 resolution in the client's eventloop.

169 thread has been killed, on ub_ctx_delete, to avoid hangs.
172 - more fixes that I overlooked.
173 - review fixes from Willem.

185 - Fix uninit variable in fix#516.
188 - Fix#516 dnssec lameness detection for answers that are improper.
194 - Fix#512 memleak in testcode for testbound (if it fails).
195 - Fix#512 NSS returned arrays out of setup function to be statics.

218 - Fixup manpage syntax.
221 - get_option and set_option support for log-time-ascii, python-script
222 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
223 immediately. The others are mostly useful for libunbound users.
226 - get_option, set_option, unbound-checkconf -o and libunbound
227 getoption and setoption support cache-min-ttl and cache-max-ttl.
230 - Fix#501: forward-first does not recurse, when forward name is ".".
231 - iana portlist update.
232 - Max include depth is unlimited.
235 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply
236 patch to it to not fail when -Werror is also specified, from the
238 - iana portlist update.
241 - Explain bogus and secure flags in libunbound more.

661 logs, high verbosity will show them.
663 16 February 2012: Wouter
664 - iter_hints is now thread-owned in module env, and thus threadsafe.
665 - Fix prefetch and sticky NS, now the prefetch works. It picks
666 nameservers that 'would be valid in the future', and if this makes
667 the NS timeout, it updates that NS by asking delegation from the
668 parent again. If child NS has longer TTL, that TTL does not get
669 refreshed from the lookup to the child nameserver.
671 15 February 2012: Wouter
672 - Fix forward-zone memory, uses malloc and frees original root dp.
673 - iter hints (stubs) uses malloc inside for more dynamicity.
674 - unbound-control forward_add, forward_remove, stub_add, stub_remove
675 can modify stubs and forwards for running unbound (on mobile computer)
676 they can also add and remove domain-insecure for the zone.
678 14 February 2012: Wouter

692 9 February 2012: Wouter
693 - Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
695 8 February 2012: Wouter
696 - implement draft-ietf-dnsext-ecdsa-04; which is in IETF LC; This
697 implementation is experimental at this time and not recommended
698 for use on the public internet (the protocol numbers have not

712 1 February 2012: Wouter
713 - Fix validation failures (like: validation failure xx: no NSEC3
714 closest encloser from yy for DS zz. while building chain of trust,
715 because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
716 for an NSEC3. Now it does not change rdata, and fixes TTL.
718 30 January 2012: Wouter
719 - Fix version-number in libtool to be version-info so it produces
720 libunbound.so.2 like it should.
722 26 January 2012: Wouter
723 - Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.

732 - Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
734 19 January 2012: Wouter
735 - Fix to write key files completely to a temporary file, and if that
736 succeeds, replace the real key file. So failures leave a useful file.
738 18 January 2012: Wouter
739 - tag 1.4.15rc1 created
740 - updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
742 17 January 2012: Wouter
743 - Fix bug where canonical_compare of RRSIG did not downcase the
744 signer-name. This is mostly harmless because RRSIGs do not have
745 to be sorted in canonical order, usually.
747 12 January 2012: Wouter
748 - bug#428: add ub_version() call to libunbound. API version increase,
749 with (binary) backwards compatibility for the previous version.
751 10 January 2012: Wouter
752 - Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
753 that would be permissible by the RFCs but it is not the TTL in the
755 - iana portlist updated.
756 - uninitialised variable in reprobe for rtt blocked domains fixed.
757 - lintfix and new flex output.
759 2 January 2012: Wouter
760 - Fix to randomize hash function, based on 28c3 congress, reported
763 24 December 2011: Wouter
764 - Fix for memory leak (about 20 bytes when a tcp or udp send operation
765 towards authority servers failed, takes about 50.000 such failures to
766 leak one Mb, such failures are also usually logged), reported by
768 - iana portlist updated.
770 19 December 2011: Wouter
771 - Fix for VU#209659 CVE-2011-4528: Unbound denial of service
772 vulnerabilities from nonstandard redirection and denial of existence

780 - Fix parse error on negative SOA RRSIGs if badly ordered in the packet.
782 13 December 2011: Wouter
783 - iana portlist updated.
785 - fix infra cache comparison.

797 30 November 2011: Wouter
798 - Fix for tcp-upstream and ssl-upstream for if a laptop sleeps, causes
799 SERVFAILs. Also fixed for UDP (but less likely).
801 28 November 2011: Wouter
802 - Fix quartile time estimate, it was too low, (thanks Jan Komissar).
803 - iana ports updated.
805 11 November 2011: Wouter
806 - Makefile compat with SunOS make, BSD make and GNU make.
807 - iana ports updated.

830 - dns over ssl support, ssl-service-pem and ssl-service-key files
831 can be given and then TCP queries are serviced wrapped in SSL.
833 27 October 2011: Wouter
834 - lame-ttl and lame-size options no longer exist, it is integrated
835 with the host info. They are ignored (with verbose warning) if
836 encountered to keep the config file backwards compatible.
837 - fix iana-update for changing gzip compression of results.
838 - fix export-all-symbols on OSX.
840 26 October 2011: Wouter
841 - iana portlist updated.
842 - Infra cache stores information about ping and lameness per IP, zone.
844 - fix iana_update target for gzipped file on iana site.
846 24 October 2011: Wouter
847 - Fix resolve of partners.extranet.microsoft.com with a fix for the
848 server selection for choosing out of a (particular) list of bad
850 - Fix make_new_space function so that the incoming query is not
851 overwritten if a jostled out query causes a waiting query to be
852 resumed that then fails and sends an error message. (Thanks to
855 21 October 2011: Wouter
856 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
857 option enabled because of memory layout exe vs dll.
859 19 October 2011: Wouter
860 - fix unbound-anchor for broken strptime on OSX lion, detected
862 - Detect if GOST really works, openssl1.0 on OSX fails.
863 - Implement ipv6%interface notation for scope_id usage.
865 17 October 2011: Wouter
866 - better documentation for inform_super (Thanks Yang Zhe).
868 14 October 2011: Wouter
869 - Fix for out-of-memory condition in libunbound (thanks
872 13 October 2011: Wouter
873 - Fix --enable-allsymbols, it depended on link specifics of the
874 target platform, or fptr_wlist assertion failures could occur.
876 12 October 2011: Wouter
877 - updated contrib/unbound_munin_ to family=auto so that it works with
878 munin-node-configure automatically (if installed as
879 /usr/local/share/munin/plugins/unbound_munin_ ).
881 27 September 2011: Wouter
882 - unbound.exe -w windows option for start and stop service.
884 23 September 2011: Wouter
885 - TCP-upstream calculates tcp-ping so server selection works if there
888 20 September 2011: Wouter
889 - Fix classification of NS set in answer section, where there is a
890 parent-child server, and the answer has the AA flag for dir.slb.com.
891 Thanks to Amanda Constant from Secure64.
893 16 September 2011: Wouter
894 - fix bug #408: accept patch from Steve Snyder that comments out
895 unused functions in lookup3.c.
896 - iana portlist updated.
897 - fix EDNS1480 change memleak and TCP fallback.
898 - fix various compiler warnings (reported by Paul Wouters).
899 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
900 fetch if sentcount > 3, stop query if sentcount > 16. Count is
901 reset when referral or CNAME happens. This makes unbound better
902 at managing large NS sets, they are explored when there is continued
903 interest (in the form of queries).
905 15 September 2011: Wouter
907 - trunk contains 1.4.14 in development.
908 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
910 12 September 2011: Wouter
911 - Reverted dns EDNS backoff fix, it did not help and needs
912 fragmentation fixes instead.
915 7 September 2011: Wouter
916 - Fix operation in ipv6 only (do-ip4: no) mode.
918 6 September 2011: Wouter
919 - fedora specfile updated.
921 5 September 2011: Wouter
924 2 September 2011: Wouter
925 - iana portlist updated.
927 26 August 2011: Wouter
928 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
929 - Fix validation failures due to EDNS backoff retries, the retry
930 for fetch of data has want_dnssec because the iter_indicate_dnssec
931 function returns true when validation failure retry happens, and
932 then the serviced query code does not fallback to noEDNS, even if
933 the cache says it has this. This helps for DLV deployment when
934 the DNSSEC status is not known for sure before the lookup concludes.
936 24 August 2011: Wouter
937 - Applied patch from Karel Slany that fixes a memory leak in the
938 unbound python module, in string conversions.
940 22 August 2011: Wouter
941 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
942 Zhang and Luo Ce). Unbound responds with the RR types that are
943 available at the name for qtype ANY and validates those RR types.
944 It does not test for completeness (i.e. with NSEC or NSEC3 query),
945 and it does not follow the CNAME or DNAME to another name (with
946 even more data for the already large response).
947 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
948 - Documented the options that work with control set_option command.
949 - tcp-upstream yes/no option (works with set_option) for tunnels.
951 18 August 2011: Wouter
952 - fix autoconf call in makedist crosscompile to RC or snapshot.
954 17 August 2011: Wouter

957 - iana portlist updated.
959 10 August 2011: Wouter
960 - Fix python site-packages path to /usr/lib64.
961 - updated patch from Tom.
962 - fix memory and fd leak after out-of-memory condition.
964 9 August 2011: Wouter
965 - patch from Tom Hendrikx fixes load of python modules.
967 8 August 2011: Wouter
968 - make clean had ldns-src reference, removed.
970 1 August 2011: Wouter
971 - Fix autoconf 2.68 warnings
974 - Unbound implements RFC6303 (since version 1.4.7).
975 - tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
976 meantime, those are for 1.4.13).
977 - iana portlist updated.
980 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
983 - Fix wildcard expansion no-data reply under an optout NSEC3 zone is
984 validated as insecure, reported by Jia Li (lijia@cnnic.cn).
987 - 1.4.12rc1 tag created.
990 - version number in example config file.
991 - fix that --enable-static-exe does not complain about it unknown.

995 - iana portlist updated.
996 - fix bug#395: id bits of other query may leak out under conditions
997 - fix replyaddr count wrong after jostled queries, which leads to
998 eventual starvation where the daemon has no replyaddrs left to use.
999 - fix comment about rndc port, that referred to the old port number.
1000 - fix that the listening socket is not closed when too many remote
1001 control connections are made at the same time.
1002 - removed ldns-src tarball inside the unbound tarball.
1004 23 June 2011: Wouter
1005 - Changed -flto check to support clang compiler.
1006 - tag 1.4.11rc3 created.
1008 17 June 2011: Wouter
1009 - tag 1.4.11rc1 created.
1010 - remove warning about signed/unsigned from flex (other flex version).
1011 - updated aclocal.m4 and libtool to match.
1012 - tag 1.4.11rc2 created.
1014 16 June 2011: Wouter
1015 - log-queries: yesno option, default is no, prints querylog.
1016 - version is 1.4.11.
1018 14 June 2011: Wouter
1019 - Use -flto compiler flag for link time optimization, if supported.
1020 - iana portlist updated.
1022 12 June 2011: Wouter
1023 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
1025 10 June 2011: Wouter
1026 - unbound-control has version number in the header,
1027 UBCT[version]_space_ is the header sent by the client now.
1028 - Unbound control port number is registered with IANA:
1029 ub-dns-control 8953/tcp unbound dns nameserver control
1030 This is the new default for the control-port config setting.
1031 - statistics-interval prints the number of jostled queries to log.
1034 - Fix Makefile for U in environment, since wrong U is more common than
1035 deansification necessity.
1036 - iana portlist updated.
1037 - updated ldns tarball to 1.6.10rc2 snapshot of today.
1040 - Fix assertion failure when unbound generates an empty error reply
1041 in response to a query, CVE-2011-1922 VU#531342.
1042 - This fix is in tag 1.4.10.
1043 - defense in depth against the above bug, an error is printed to log
1044 instead of an assertion failure.
1047 - bug#386: --enable-allsymbols option links all binaries to libunbound
1048 and reduces install size significantly.
1049 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
1050 - iana portlist updated.
1051 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
1053 14 April 2011: Wouter
1054 - configure created with newer autoconf 2.66.
1056 12 April 2011: Wouter
1057 - bug#378: Fix that configure checks for ldns_get_random presence.
1059 8 April 2011: Wouter
1060 - iana portlist updated.
1061 - queries with CD flag set cause DNSSEC validation, but the answer is
1062 not withheld if it is bogus. Thus, unbound will retry if it is bad
1063 and curb the TTL if it is bad, thus protecting the cache for use by
1064 downstream validators.
1065 - val-override-date: -1 ignores dates entirely, for NTP usage.
1067 29 March 2011: Wouter
1068 - harden-below-nxdomain: changed so that it activates when the
1069 cached nxdomain is dnssec secure. This avoids backwards
1070 incompatibility because those old servers do not have dnssec.
1072 24 March 2011: Wouter
1073 - iana portlist updated.
1077 17 March 2011: Wouter
1078 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
1079 Applied but did not do the --disable-gost.
1081 10 March 2011: Wouter
1082 - tag 1.4.9 release candidate 1 created.
1084 3 March 2011: Wouter
1085 - updated ldns to today.
1087 1 March 2011: Wouter
1088 - Fix no ADflag for NXDOMAIN in NSEC3 optout. And wildcard in optout.
1089 - give config parse error for multiple names on a stub or forward zone.
1090 - updated ldns tarball to 1.6.9(todays snapshot).
1092 24 February 2011: Wouter
1093 - bug #361: Fix, time.elapsed variable not reset with stats_noreset.

1099 18 February 2011: Wouter
1100 - common.sh in testdata updated to version 2.
1102 15 February 2011: Wouter
1103 - Added explicit note on unbound-anchor usage:
1104 Please note usage of unbound-anchor root anchor is at your own risk
1105 and under the terms of our LICENSE (see that file in the source).
1107 11 February 2011: Wouter
1108 - iana portlist updated.
1109 - tpkg updated with common.sh for common functionality.
1111 7 February 2011: Wouter
1112 - Added regression test for addition of a .net DS to the root, and
1113 cache effects with different TTL for glue and DNSKEY.
1114 - iana portlist updated.
1116 28 January 2011: Wouter
1117 - Fix remove private address does not throw away entire response.
1119 24 January 2011: Wouter
1122 19 January 2011: Wouter
1123 - fix bug#349: no -L/usr for ldns.
1125 18 January 2011: Wouter
1126 - ldns 1.6.8 tarball included.
1129 17 January 2011: Wouter
1130 - add get and set option for harden-below-nxdomain feature.
1131 - iana portlist updated.
1133 14 January 2011: Wouter
1134 - Fix so a changed NS RRset does not get moved name stuck on old
1135 server, for type NS the TTL is not increased.
1137 13 January 2011: Wouter
1138 - Fix prefetch so it does not get stuck on old server for moved names.
1140 12 January 2011: Wouter
1141 - iana portlist updated.
1143 11 January 2011: Wouter
1144 - Fix insecure CNAME sequence marked as secure, reported by Bert
1147 10 January 2011: Wouter
1148 - faster lruhash get_mem routine.
1150 4 January 2011: Wouter
1151 - bug#346: remove ITAR scripts from contrib, the service is discontinued, use the root.
1152 - iana portlist updated.
1154 23 December 2010: Wouter
1155 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
1157 21 December 2010: Wouter
1158 - algorithm compromise protection using the algorithms signalled in
1159 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
1160 and thus, if you have multiple algorithms in your trust-anchor-file
1161 then it will now behave different than before. Also, 5011 rollover
1162 for algorithms needs to be double-signature until the old algorithm
1164 It is not an option, because I see no use to turn the security off.
1165 - iana portlist updated.
1167 17 December 2010: Wouter
1168 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
1169 - fix validation in this case: CNAME to nodata for co-hosted opt-in
1170 NSEC3 insecure delegation, was bogus, fixed to be insecure.
1172 16 December 2010: Wouter
1173 - Fix our 'BDS' license (typo reported by Xavier Belanger).
1175 10 December 2010: Wouter

1187 - iana portlist updated.
1189 18 November 2010: Wouter
1190 - harden-below-nxdomain option, default off (because very old
1191 software may be incompatible). We could enable it by default in
1194 17 November 2010: Wouter
1195 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
1196 - make test output nicer.
1198 15 November 2010: Wouter
1199 - silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
1200 - iana portlist updated.
1201 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
1203 9 November 2010: Wouter
1204 - unbound-anchor compiles with openssl 0.9.7.
1206 8 November 2010: Wouter
1207 - release tag 1.4.7.
1208 - trunk is version 1.4.8.
1209 - Be lenient and accept imgw.pl malformed packet (like BIND).

1212 - do not synthesize a CNAME message from cache for qtype DS.
1214 4 November 2010: Wouter
1215 - Use central entropy to seed threads.
1217 3 November 2010: Wouter
1218 - Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
1220 2 November 2010: Wouter
1224 1 November 2010: Wouter
1225 - GOST code enabled by default (RFC 5933).
1227 27 October 2010: Wouter
1228 - Fix uninit value in dump_infra print.
1229 - Fix validation failure for parent and child on same server with an
1230 insecure childzone and a CNAME from parent to child.
1231 - Configure detects libev-4.00.
1233 26 October 2010: Wouter
1234 - dump_infra and flush_infra commands for unbound-control.
1235 - no timeout backoff if meanwhile a query succeeded.
1236 - Change of timeout code. No more lost and backoff in blockage.
1237 At 12sec timeout (and at least 2x lost before) one probe per IP
1238 is allowed only. At 120sec, the IP is blocked. After 15min, a
1239 120sec entry has a single retry packet.
1241 25 October 2010: Wouter
1242 - Configure errors if ldns is not found.
1244 22 October 2010: Wouter
1245 - Windows 7 fix for the installer.
1247 21 October 2010: Wouter
1248 - Fix bug where fallback_tcp causes wrong roundtrip and edns
1249 observation to be noted in cache. Fix bug where EDNSprobe halted
1250 exponential backoff if EDNS status unknown.
1251 - new unresponsive host method, exponentially increasing block backoff.
1252 - iana portlist updated.
1254 20 October 2010: Wouter
1255 - interface automatic works for some people with ip6 disabled.
1256 Therefore the error check is removed, so they can use the option.
1258 19 October 2010: Wouter
1259 - Fix for request list growth, if a server has long timeout but the
1260 lost counter is low, then its effective rtt is the one without
1261 exponential backoff applied. Because the backoff is not working.
1262 The lost counter can then increase and the server is blacklisted,
1263 or the lost counter does not increase and the server is working
1266 18 October 2010: Wouter
1267 - iana portlist updated.
1269 13 October 2010: Wouter
1270 - Fix TCP so it uses a random outgoing-interface.
1271 - unbound-anchor handles ADDPEND keystate.
1273 11 October 2010: Wouter
1274 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
1275 the zone has a secure delegation hosted on the same server did not
1276 verify as secure (it was insecure by mistake).
1277 - iana portlist updated.
1278 - ldns tarball updated (for reading cachedumps with bad RR data).
1280 1 October 2010: Wouter

1282 - Fix alloc_reg_release for longer uptime in out of memory conditions.
1284 28 September 2010: Wouter
1285 - unbound-anchor working, it creates or updates a root.key file.
1286 Use it before you start the validator (e.g. at system boot time).
1288 27 September 2010: Wouter
1289 - iana portlist updated.
1291 24 September 2010: Wouter
1292 - bug#329: in example.conf show correct ipv4 link-local 169.254/16.
1294 23 September 2010: Wouter
1295 - unbound-anchor app, unbound requires libexpat (xml parser library).
1297 22 September 2010: Wouter
1298 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
1299 reverse ipv6 orchid prefix from builtin list.
1300 - iana portlist updated.
1302 17 September 2010: Wouter
1303 - DLV has downgrade protection again, because the RFC says so.
1304 - iana portlist updated.
1306 16 September 2010: Wouter
1307 - Algorithm rollover operational reality intrudes, for trust-anchor,
1308 5011-store, and DLV-anchor if one key matches it's good enough.
1309 - iana portlist updated.
1310 - Fix reported validation error in out of memory condition.
1312 15 September 2010: Wouter
1313 - Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
1315 14 September 2010: Wouter
1316 - increased mesh-max-activation from 1000 to 3000 for crazy domains
1317 like _tcp.slb.com with 262 servers.
1318 - iana portlist updated.
1320 13 September 2010: Wouter
1321 - bug#327: Fix for cannot access stub zones until the root is primed.
1323 9 September 2010: Wouter
1324 - unresponsive servers are not completely blacklisted (because of
1325 firewalls), but also not probed all the time (because of the request
1326 list size it generates). The probe rate is 1%.
1327 - iana portlist updated.
1329 20 August 2010: Wouter
1330 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
1331 iterator get_mem includes priv_get_mem. delegpt nodup removed.
1332 listen_pushback, query_info_allocqname, write_socket, send_packet,
1333 comm_point_set_cb_arg and listen_resume removed.
1335 19 August 2010: Wouter
1336 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
1337 Delegpt structures checked for duplicates always.
1338 No more nameserver lookups generated when depth is full anyway.

1340 - iana portlist updated.
1342 18 August 2010: Wouter
1343 - Fix bug#322: configure does not respect CFLAGS on Solaris.
1344 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
1345 if use sun-cc, but some systems need different flags.
1347 16 August 2010: Wouter
1348 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
1349 changes, uses m4_bpatsubst now.
1350 - make test (or make check) should be more portable and run the unit
1351 test and testbound scripts. (make longtest has special requirements).
1353 13 August 2010: Wouter
1354 - More pleasant remote control command parsing.
1355 - documentation added for return values reported by doxygen 1.7.1.
1356 - iana portlist updated.
1358 9 August 2010: Wouter

1374 22 July 2010: Wouter
1375 - more error details on failed remote control connection.
1377 15 July 2010: Wouter
1378 - rlimit adjustments for select and ulimit can happen at the same time.
1380 14 July 2010: Wouter
1381 - Donation text added to README.
1382 - Fix integer underflow in prefetch ttl creation from cache. This
1383 fixes a potential negative prefetch ttl.
1385 12 July 2010: Wouter
1386 - Changed the defaults for num-queries-per-thread/outgoing-range.
1387 For builtin-select: 512/960, for libevent 1024/4096 and for
1388 windows 24/48 (because of win api). This makes the ratio this way
1389 to improve resilience under heavy load. For high performance, use
1390 libevent and possibly higher numbers.
1392 10 July 2010: Wouter
1393 - GOST enabled if SSL is recent and ldns has GOST enabled too.
1394 - ldns tarball updated.
1397 - iana portlist updated.
1398 - Fix validation of qtype DNSKEY when a key-cache entry exists but
1399 no rr-cache entry is used (it expired or prefetch), it then goes
1400 back up to the DS or trust-anchor to validate the DNSKEY.
1403 - Neat function prototypes, unshadowed local declarations.
1406 - failure to chown the pidfile is not fatal any more.
1407 - testbound uses UTC timezone.
1408 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
1409 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
1412 - log if a server is skipped because it is on the donotquery list,
1413 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
1414 - added feature to print configure date, target and options with -h.
1415 - added feature to print event backend system details with -h.
1416 - wdiff is not actually required by make test, updated requirements.
1419 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
1420 must be signed with all algorithms from the DS rrset at the parent.
1421 This is now checked and becomes bogus if not.
1423 28 June 2010: Wouter
1424 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
1425 in overload situations to be about 5 qps for the class of shortly
1427 The capacity of the resolver is then about (numqueriesperthread / 2)
1428 / (average time for such long queries) qps for long queries.
1429 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
1430 qps for short queries, per thread.
1431 - Fix the max number of reply-address count to be applied for duplicate
1432 queries, and not for new query list entries. This raises the memory
1433 usage to a max of (16+1)*numqueriesperthread reply addresses.
1435 25 June 2010: Wouter
1436 - Fix handling of corner case reply from lame server, follows rfc2308.
1437 It could lead to a nodata reply getting into the cache if the search
1438 for a non-lame server turned up other misconfigured servers.
1439 - unbound.h has extern "C" statement for easier include in c++.
1441 23 June 2010: Wouter
1442 - iana portlist updated.
1443 - makedist upgraded cross compile openssl option, like this:
1444 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
1446 22 June 2010: Wouter
1447 - Unbound reports libev or libevent correctly in logs in verbose mode.
1448 - Fix to unload gost dynamic library module for leak testing.
1450 18 June 2010: Wouter
1451 - iana portlist updated.
1453 17 June 2010: Wouter
1454 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
1456 16 June 2010: Wouter
1457 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
1458 assertion was wrong.
1459 - updated ldns tarball.
1461 15 June 2010: Wouter
1462 - tag 1.4.5 created.
1463 - trunk contains 1.4.6 in development.
1464 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
1465 - Fix to use one pointer less for iterator query state store_parent_NS.
1466 - makedist crosscompile to windows uses builtin ldns not host ldns.
1467 - Max referral count from 30 to 130, because 128 one character domains
1469 - added documentation for the histogram printout to syslog.
1471 11 June 2010: Wouter
1472 - When retry to parent the retrycount is not wiped, so failed
1473 nameservers are not tried again.
1474 - iana portlist updated.
1476 10 June 2010: Wouter
1477 - Fix bug where a long loop could be entered, now cycle detection
1478 has a loop-counter and maximum search amount.
1481 - iana portlist updated.
1482 - 1.4.5rc1 tag created.
1485 - ldns tarball updated, 1.6.5.
1486 - review comments, split dependency cycle tracking for parentside
1487 last resort lookups for A and AAAA so there are more lookup options.
1490 - Fix compile warning if compiled without threads.
1491 - updated ldns-tarball with current ldns svn (pre 1.6.5).
1492 - GOST disabled-by-default, the algorithm number is allocated but the
1493 RFC is still has to pass AUTH48 at the IETF.
1496 - Ignore Z flag in incoming messages too.
1497 - Fix storage of negative parent glue if that last resort fails.
1498 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
1499 - new splint flags for newer splint install.
1502 - Fix AD flag handling, it could in some cases mistakenly copy the AD
1503 flag from upstream servers.
1504 - alloc_special_obtain out of memory is not a fatal error any more,
1505 enabling unbound to continue longer in out of memory conditions.
1506 - parentside names are dispreferred but not said to be dnssec-lame.
1507 - parentside check for cached newname glue.
1508 - fix parentside and querytargets modulestate, for dump_requestlist.
1509 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
1510 - fix parentside from cache to be marked dispreferred for bad names.
1513 - iana portlist updated.
1514 - parent-child disagreement approach altered. Older fixes are
1515 removed in place of a more exhaustive search for misconfigured data
1516 available via the parent of a delegation.
1517 This is designed to be throttled by cache entries, with TTL from the
1518 parent if possible. Additionally the loop-counter is used.
1519 It also tests for NS RRset differences between parent and child.
1520 The fetch of misconfigured data should be more reliable and thorough.
1521 It should work reliably even with no or only partial data in cache.
1522 Data received from the child (as always) is deemed more
1523 authoritative than information received from the delegation parent.
1524 The search for misconfigured data is not performed normally.
1527 - Contribution from Migiel de Vos (Surfnet): nagios patch for
1528 unbound-host, in contrib/ (in the source tarball). Makes
1529 unbound-host suitable for monitoring dnssec(-chain) status.
1532 - EDNS timeout code will not fire if EDNS status already known.
1533 - EDNS failure not stored if EDNS status known to work.
1536 - Fix resolution for domains like safesvc.com.cn. If the iterator
1537 can not recurse further and it finds the delegation in a state
1538 where it would otherwise have rejected it outhand if so received
1539 from a cache lookup, then it can try to ask higherup (with loop
1541 - Fix comments in iter_utils:dp_is_useless.
1544 - Fix various compiler warnings from the clang llvm compiler.
1545 - iana portlist updated.
1548 - Fix bug#308: spelling error in variable name in parser and lexer.
1551 - Fix dnssec-missing detection that was turned off by server selection.
1552 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
1553 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
1554 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
1556 29 April 2010: Wouter
1557 - Fix for dnssec lameness detection to use the key cache.
1558 - infra cache entries that are expired are wiped clean. Previously
1559 it was possible to not expire host data (if accessed often).
1561 28 April 2010: Wouter
1562 - ldns tarball updated and GOST support is detected and then enabled.
1563 - iana portlist updated.
1564 - Fix detection of gost support in ldns (reported by Chris Smith).
1566 27 April 2010: Wouter
1567 - unbound-control get_option domain-insecure shows config file items.
1568 - fix retry sequence if prime hints are recursion-lame.
1569 - autotrust anchor file can be initialized with a ZSK key as well.
1570 - harden-referral-path does not result in failures due to max-depth.
1571 You can increase the max-depth by adding numbers (' 0') after the
1572 target-fetch-policy, this increases the depth to which is checked.
1574 26 April 2010: Wouter
1575 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
1576 CPPFLAGS during configure process.
1577 - if libev is installed on the base system (not libevent), detect
1578 it from the event.h header file and link with -lev.
1579 - configlexer.lex gets config.h, and configyyrename.h added by make,
1580 no more double include.
1581 - More strict scrubber (Thanks to George Barwood for the idea):
1582 NS set must be pertinent to the query (qname subdomain nsname).
1583 - Fix bug#307: In 0x20 backoff fix fallback so the number of
1584 outstanding queries does not become -1 and block the request.
1585 Fixed handling of recursion-lame in combination with 0x20 fallback.
1586 Fix so RRsets are compared canonicalized and sorted if the immediate
1587 comparison fails, this makes it work around round-robin sites.
1589 23 April 2010: Wouter
1590 - Squelch log message: sendto failed permission denied for
1591 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
1592 - Fix to fetch data as last resort more tenaciously. When cycle
1593 targets cause the server selection to believe there are more options
1594 when they really are not there, the server selection is reinitiated.
1595 - Fix fetch from blacklisted dnssec lame servers as last resort. The
1596 server's IP address is then given in validator errors as well.
1597 - Fix local-zone type redirect that did not use the query name for
1600 22 April 2010: Wouter
1602 - trunk contains 1.4.5 in development.
1603 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
1604 The validator error message was 'no signatures from ...'.
1606 16 April 2010: Wouter
1607 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
1610 15 April 2010: Wouter
1611 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
1612 example key and signatures for GOST. GOST requires openssl-1.0.0.
1613 GOST is still disabled by default.
1615 9 April 2010: Wouter
1616 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
1617 get into an endless loop, if 0x20 was enabled, and buffers are small
1618 or particular broken packets are received.
1619 - Fix chain of trust with CNAME at an intermediate step, for the DS
1622 8 April 2010: Wouter
1623 - Fix validation of queries with wildcard names (*.example).
1625 6 April 2010: Wouter
1626 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
1627 cache timeout coincided with a server update, the current EDNS
1628 backoff is less sensitive, and does not cache the backoff unless
1629 the backoff actually works and the domain is not expecting DNSSEC.
1630 - GOST support with correct algorithm numbers.
1632 1 April 2010: Wouter
1633 - iana portlist updated.
1635 24 March 2010: Wouter
1636 - unbound control flushed items are not counted when flushed again.
1638 23 March 2010: Wouter
1639 - iana portlist updated.
1641 22 March 2010: Wouter
1642 - unbound-host disables use-syslog from config file so that the
1643 config file for the main server can be used more easily.
1644 - fix bug#301: unbound-checkconf could not parse interface
1645 '0.0.0.0@5353', even though unbound itself worked fine.
1647 19 March 2010: Wouter
1648 - fix fwd_ancil test to pass if the socket options are not supported.
1650 18 March 2010: Wouter
1651 - Fixed random numbers for port, interface and server selection.
1652 Removed very small bias.
1653 - Refer to the listing in unbound-control man page in the extended
1654 statistics entry in the unbound.conf man page.
1656 16 March 2010: Wouter
1657 - Fix interface-automatic for OpenBSD: msg.controllen was too small,
1658 also assertions on ancillary data buffer.
1659 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
1660 - for NSEC3 check if signatures are cached.
1662 15 March 2010: Wouter
1663 - unit test for util/regional.c.
1665 12 March 2010: Wouter
1666 - Reordered configure checks so fork and -lnsl -lsocket checks are
1667 earlier, and thus later checks benefit from and do not hinder them.
1668 - iana portlist updated.
1669 - ldns tarball updated.
1670 - Fix python use when multithreaded.
1671 - Fix solaris python compile.
1672 - Include less in config.h and include per code file for ldns, ssl.
1674 11 March 2010: Wouter
1675 - another memory allocation option: --enable-alloc-nonregional.
1676 exposes the regional allocations to other memory purifiers.
1677 - fix for memory alignment in struct sock_list allocation.
1678 - Fix for MacPorts ldns without ssl default, unbound checks if ldns
1679 has dnssec functionality and uses the builtin if not.
1680 - Fix daemonize on Solaris 10, it did not detach from terminal.
1681 - tag 1.4.3 created.
1682 - trunk is 1.4.4 in development.
1683 - spelling fix in validation error involving cnames.
1685 10 March 2010: Wouter
1686 - --enable-alloc-lite works with test set.
1687 - portability in the testset: printf format conversions, prototypes.
1689 9 March 2010: Wouter
1690 - tag 1.4.2 created.
1691 - trunk is 1.4.3 in development.
1692 - --enable-alloc-lite debug option.
1694 8 March 2010: Wouter
1695 - iana portlist updated.
1697 4 March 2010: Wouter
1698 - Fix crash in control channel code.
1700 3 March 2010: Wouter
1701 - better casts in pipe code, brackets placed wrongly.
1702 - iana portlist updated.
1704 1 March 2010: Wouter
1705 - make install depends on make all.
1706 - Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
1707 - --enable-checking: enables assertions but does not look nonproduction.
1708 - nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
1709 nxdomain and nodata distinguished.
1710 - ldns tarball updated.
1711 - --disable-rpath fixed for libtool not found errors.
1712 - new fedora specfile from Fedora13 in contrib from Paul Wouters.
1714 26 February 2010: Wouter
1715 - Fixup prototype for lexer cleanup in daemon code.
1716 - unbound-control list_stubs, list_forwards, list_local_zones and
1719 24 February 2010: Wouter
1720 - Fix scrubber bug that potentially let NS records through. Reported
1722 - Also delete potential poison references from additional.
1723 - Fix: no classification of a forwarder as lame, throw away instead.
1725 23 February 2010: Wouter
1726 - libunbound ub_ctx_get_option() added.
1727 - unbound-control set_option and get_option commands.
1728 - iana portlist updated.
1730 18 February 2010: Wouter
1731 - A little more strict DS scrubbing.
1732 - No more blacklisting of unresponsive servers, a 2 minute timeout
1734 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.
1735 - pickup ldns compile fix, libdl for libcrypto.
1736 - log 'tcp connect: connection timed out' only in high verbosity.
1737 - unbound-control log_reopen command.
1738 - moved get_option code from unbound-checkconf to util/config_file.c
1740 17 February 2010: Wouter
1741 - Disregard DNSKEY from authority section for chain of trust.
1742 DS records that are irrelevant to a referral scrubbed. Anti-poison.
1743 - iana portlist updated.
1745 16 February 2010: Wouter
1746 - Check for 'no space left on device' (or other errors) when
1747 writing updated autotrust anchors and print errno to log.
1749 15 February 2010: Wouter
1750 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
1751 hardcoded. We made the choice to send out more conservatively,
1752 protecting against an aggregate effect more than protecting a
1753 single user (from their own folly, perhaps in case of misconfig).
1755 12 February 2010: Wouter
1756 - Re-query pattern changed on validation failure. To protect troubled
1757 authority servers, unbound caches a failure for the DNSKEY or DS
1758 records for the entire zone, and only retries that 900 seconds later.
1759 This implies that only a handful of packets are sent extra to the
1760 authority if the zone fails.
1762 11 February 2010: Wouter
1763 - ldns tarball update for long label length syntax error fix.
1764 - iana portlist updated.
1766 9 February 2010: Wouter
1767 - Fixup in compat snprintf routine, %f 1.02 and %g support.
1768 - include math.h for testbound test compile portability.
1770 2 February 2010: Wouter
1771 - Updated url of IANA itar, interim trust anchor repository, in script.
1773 1 February 2010: Wouter
1774 - iana portlist updated.
1775 - configure test for memcmp portability.
1777 27 January 2010: Wouter
1778 - removed warning on format string in validator error log statement.
1779 - iana portlist updated.
1781 22 January 2010: Wouter
1782 - libtool finish the install of unbound python dynamic library.
1784 21 January 2010: Wouter
1785 - acx_nlnetlabs.m4 synchronised with nsd's version.
1787 20 January 2010: Wouter
1788 - Fixup lookup trouble for parent-child domains on the first query.
1790 14 January 2010: Wouter
1791 - Fixup ldns detection to also check for header files.
1793 13 January 2010: Wouter
1794 - prefetch-key option that performs DNSKEY queries earlier in the
1795 validation process, and that could halve the latency on DNSSEC
1796 queries. It takes some extra processing (CPU, a cache is needed).
1798 12 January 2010: Wouter
1799 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
1801 8 January 2010: Wouter
1802 - Fix for parent-child disagreement code which could have trouble
1803 when (a) ipv6 was disabled and (b) the TTL for parent and child
1804 were different. There were two bugs, the parent-side information
1805 is fixed to no longer block lookup of child side information and
1806 the iterator is fixed to no longer attempt to get ipv6 when it is
1807 not enabled and then give up in failure.
1808 - test and fixes to make prefetch actually store the answer in the
1809 cache. Considers some rrsets 'already expired' but does not allow
1810 overwriting of rrsets considered more secure.
1812 7 January 2010: Wouter
1813 - Fixup python documentation (thanks Leo Vandewoestijne).
1814 - Work on cache prefetch feature.

1852 errors generated for domain names like '.example.com'.
1853 - Fix SOA excluded from negative DS responses. Reported by Hauke
1854 Lampe. The negative cache did not include proper SOA records for
1855 negative qtype DS responses which makes BIND barf on it, such
1856 responses are now only used internally.
1857 - Fix negative cache lookup of closestencloser check of DS type bit.
1859 8 December 2009: Wouter
1860 - Fix for lookup of parent-child disagreement domains, where the
1861 parent-side glue works but it does not provide proper NS, A or AAAA
1862 for itself, fixing domains such as motorcaravanners.eu.
1863 - Feature: you can specify a port number in the interface: line, so
1864 you can bind the same interface multiple times at different ports.
1866 7 December 2009: Wouter
1867 - Bug#287: Fix segfault when unbound-control remove nonexistent local
1868 data. Added check to tests.
1870 1 December 2009: Wouter

1972 the NSEC3 patch from the entry above.
1973 - val-log-level: 2 shows extended error information for validation
1974 failures, but still one (longish) line per failure. For example:
1975 validation failure <example.com. DNSKEY IN>: signature expired from
1976 192.0.2.4 for trust anchor example.com. while building chain of trust
1977 validation failure <www.example.com. A IN>: no signatures from
1978 192.0.2.6 for key example.com. while building chain of trust
1980 6 October 2009: Wouter
1981 - Test set updated to provide additional ns lookup result.
1982 The retry would attempt to fetch the data from other nameservers
1983 for bogus data, and this needed to be provisioned in the tests.

2009 - test unbound reading of original autotrust data.
2010 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
2011 picked up, otherwise performs initial probe like usual.

2040 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
2041 - use linebuffering for log-file: output, this can be significantly
2042 faster than the previous fflush method and enable some class of
2043 resolvers to use high verbosity (for short periods).
2044 Not on windows, because line buffering does not work there.
2046 9 September 2009: Wouter
2047 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
2048 The RRsets would still expire at the normal time, but this would
2049 keep messages bogus in the cache for too long.

2051 - documented that load_cache is meant for debugging.
2053 8 September 2009: Wouter

2138 14 August 2009: Wouter
2139 - unbound-control lookup prints out infra cache information, like RTT.
2140 - Fix bug in DLV lookup reported by Amanda from Secure64.
2141 It could sometimes wrongly classify a domain as unsigned, which

2266 in the wrong order would be parsed, but put wrongly into internal
2267 structures so that later validation would fail.
2268 - Extreme lenience for wrongly truncated replies where a positive

2279 - Fixup opportunistic target query generation to it does not
2280 generate queries that are known to fail.
2281 - Touchup on munin total memory report.
2282 - messages picked out of the cache by the iterator are checked

2305 They are performed to higherup domains, and thus treated as if
2306 going to higher zones when looking up the right forward or stub
2307 server. This makes a stub pointing to a local server that has
2308 a local view of example.com signed with the same keys as are
2309 publicly used work. Reported by Johan Ihren.

2312 - same thing fixed for forward-zone and DS, chain of trust from
2313 public internet into the forward-zone works now. Added unit test.
2316 - openssl key files are opened apache-style, when user is root and
2317 before chrooting. This makes permissions on remote-control key
2318 files easier to set up. Fixes bug #251.
2319 - flush_type and flush_name remove msg cache entries.
2320 - codereview - dp copy bogus setting fix.

2334 - fixup bad free() when wrongly encoded DSA signature is seen.
2335 Reported by Paul Wouters.
2336 - review comments from Matthijs.
2339 - --enable-sha2 option. The draft rsasha256 changed its algorithm
2340 numbers too often. Therefore it is more prudent to disable the
2341 RSASHA256 and RSASHA512 support by default.
2342 - ldns trunk included as new tarball.
2343 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.
2346 - fixup doc bug in README reported by Matthew Dempsky.
2349 - update iana port list
2350 - update ldns lib tarball
2353 - detect lack of IPv6 support on XP (with a different error code).
2354 - Fixup a crash-on-exit which was triggered by a very long queue.
2355 Unbound would try to re-use ports that came free, but this is
2356 of course not really possible because everything is deleted.
2357 Most easily triggered on XP (not Vista), maybe because of the
2358 network stack encouraging large messages backlogs.
2359 - change in debug statements.
2360 - Fixed bug that could cause a crash if root prime failed when there
2361 were message backlogs.
2364 - Thanks again to Brett Carr, found an assertion that was not true.
2365 Assertion checked if recursion parent query still existed.
2367 29 April 2009: Wouter
2368 - Thanks to Brett Carr, caught windows resource leak, use
2369 closesocket() and not close() on sockets or else the network stack
2370 starts to leak handles.
2371 - Removed usage of windows Mutex because windows cannot handle enough
2372 mutexes open. Provide own mutex implementation using primitives.

2423 - windows compile fix.
2424 - Detect FreeBSD jail without ipv6 addresses assigned.
2425 - python libunbound wrapper unit test.

2428 /usr/lib/python2.x/site-packages/unboundmodule.py
2429 from configure --with-pyunbound:
2430 /usr/lib/python2.x/site-packages/unbound.py
2431 /usr/lib/python2.x/site-packages/_unbound.so*
2432 The example python scripts (pythonmod/examples and

2435 - clock skew checks in unbound, config statements.
2436 - nxdomain ttl considerations in requirements.txt
2438 3 April 2009: Wouter
2439 - Fixed a bug that caused messages to be stored in the cache too
2440 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
2441 targets have been more vulnerable to the TTL miscalculation bug.
2442 - documentation test fixed for python addition.
2444 2 April 2009: Wouter
2445 - pyunbound (libunbound python plugin) compiles using libtool.

2447 - iana portlist updated.
2448 - fixed bug in unbound-control flush_zone where it would not flush
2449 every message in the target domain. This especially impacted
2450 NXDOMAIN messages which could remain in the cache regardless.
2451 - python module test package.
2453 1 April 2009: Wouter
2454 - suppress errors when trying to contact authority servers that gave
2455 ipv6 AAAA records for their nameservers with ipv4 mapped contents.

2511 18 March 2009: Wouter
2512 - Added tests, unknown algorithms become insecure. fallback works.
2513 - Fix for and test for unknown algorithms in a trust anchor
2514 definition. Trust anchors with no supported algos are ignored.
2515 This means a (higher)DS or DLV entry for them could succeed, and
2516 otherwise they are treated as insecure.
2517 - domain-insecure: "example.com" statement added. Sets domain
2518 insecure regardless of chain of trust DSs or DLVs. The inverse
2521 17 March 2009: Wouter

2546 - winsock event handler tests if signals are really signalled.
2547 - install and service with log to file works on XP and Vista on
2548 default install location.
2549 - on windows logging to the Application logbook works (as a service).
2550 - fix RUN_DIR on windows compile setting in makedist.
2551 - windows registry has Software\Unbound\ConfigFile element.
2552 If does not exist, the default is used. The -c switch overrides it.

2599 19 February 2009: Wouter
2600 - unbound-checkconf and unbound print warnings when trust anchors
2601 have unsupported algorithms.
2602 - added contrib/update-itar.sh This script is similar to
2603 update-anchor.sh, and updates from the IANA ITAR repository.
2604 You can provide your own PGP key and trust repo, or can use the
2605 builtin. The program uses wget and gpg to work.
2606 - iana portlist updated.
2607 - update-itar.sh: using ftp:// urls because https godaddy certificate
2608 is not available everywhere and then gives fatal errors. The
2609 security is provided by pgp signature.
2611 18 February 2009: Wouter
2612 - more cycle detection. Also for target queries.
2613 - fixup bug where during deletion of the mesh queries the callbacks
2614 that were reentrant caused assertion failures. Keep the mesh in
2615 a reentrant safe state. Affects libunbound, reload of server,
2616 on quit and flush_requestlist.
2617 - iana portlist updated.
2619 13 February 2009: Wouter

2624 - document that unbound-host reads no config file by default.
2625 - updated iana portlist.
2627 12 February 2009: Wouter

2637 10 February 2009: Wouter
2638 - keys with rfc5011 REVOKE flag are skipped and not considered when
2640 - iana portlist updated
2641 - #226: dump_requestlist feature for unbound-control.
2643 6 February 2009: Wouter
2644 - contrib contains specfile for fedora 1.2.1 (from Paul Wouters).

2646 - fixup EOL in include directive (reported by Paul Wouters).
2647 You can no longer specify newlines in the names of included files.
2648 - config parser changed. Gives some syntax errors closer to where they
2649 occurred. Does not enforce a space after keyword anymore.
2650 Does not allow literal newlines inside quoted strings anymore.
2651 - verbosity level 5 logs customer IP for new requestlist entries.
2652 - test fix, lexer and cancel test.
2653 - new option log-time-ascii: yes if you enable it prints timestamps
2654 in the log file as Feb 06 13:45:26 (like syslog does).
2655 - detect event_base_new in libevent-1.4.1 and later and use it.
2656 - #231 unbound-checkconf -o option prints that value from config file.
2657 Useful for scripting in management scripts and the like.
2659 5 February 2009: Wouter
2660 - ldns 1.5.0 rc as tarball included.
2661 - 1.3.0 development continues:
2662 change in libunbound API: ub_cancel can return an error, that
2663 the async_id did not exist, or that it was already delivered.
2664 The result could have been delivered just before the cancel
2665 routine managed to acquire the lock, so a caller may get the
2666 result at the same time they call cancel. For this case,
2667 ub_cancel tries to return an error code.
2668 Fixes race condition in ub_cancel() libunbound function.
2669 - MacOSX Leopard cleaner text output from configure.
2670 - initgroups(3) is called to drop secondary group permissions, if
2672 - configure option --with-ldns-builtin forces the use of the
2673 inluded ldns package with the unbound source. The -I include
2674 is put before the others, so it avoids bad include files from
2675 an older ldns install.
2676 - daemon(3) posix call is used when available.
2677 - testbound test for older fix added.
2679 4 February 2009: Wouter

2686 - updated IANA portlist.
2688 16 January 2009: Wouter
2689 - more quiet about ipv6 network failures, i.e. when ipv6 is not
2690 available (network unreachable). Debug still printed on high
2692 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
2693 debugging with unbound-host -4 -d ...
2694 - more cycle detection for NS-check, addr-check, root-prime and
2695 stub-prime queries in the iterator. Avoids possible deadlock
2698 15 January 2009: Wouter
2699 - bug #229: fixup configure checks for compilation with Solaris
2700 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc
2701 - fixup suncc warnings.
2702 - fix bug where unbound could crash using libevent 1.3 and older.
2703 - update testset for recent retry change.
2705 14 January 2009: Wouter
2706 - 1.2.1 feature: negative caching for failed queries.
2707 Queries that failed are cached for 5 seconds (NORR_TTL).
2708 If the failure is local, like out of memory, it is not cached.
2709 - the TTL comparison for the cache used different comparisons,
2710 causing many cache responses that used the iterator and validator
2711 state machines unnecessarily.
2712 - retry from 4 to 5 so that EDNS drop retry is part of the first
2713 query resolve attempt, and cached error does not stop EDNS fallback.
2714 - remove debug prints that protect against bad referrals.
2715 - honor QUIET=no on make commandline (or QUIET=yes ).
2717 13 January 2009: Wouter
2718 - fixed bug in lameness marking, removed printouts.
2719 - find NS rrset more cleanly for qtype NS.
2720 - Moved changes to 1.2.0 for release. Thanks to Mark Zealey for
2722 - 1.2.1 feature: stops resolving AAAAs promiscuously when they
2723 are in the negative cache.
2725 12 January 2009: Wouter
2726 - fixed bug in infrastructure lameness cache, did not lowercase
2727 name of zone to hash when setting lame.

2745 - typo fix and iana portlist updated.
2746 - porting testsuite; unused var warning, and type fixup.
2748 6 January 2009: Wouter
2749 - fixup packet-of-death when compiled with --enable-debug.
2750 A malformed packet could cause an internal assertion failure.
2751 - added test for HINFO canonicalisation behaviour.
2752 - fixup reported problem with transparent local-zone data where
2753 queries with different type could get nxdomain. Now queries
2754 with a different name get resolved normally, with different type
2755 get a correct NOERROR/NODATA answer.
2756 - HINFO no longer downcased for validation, making unbound compatible
2758 - fix reading included config files when chrooted.
2759 Give full path names for include files.
2760 Relative path names work if the start dir equals the working dir.
2761 - fix libunbound message transport when no packet buffer is available.
2763 5 January 2009: Wouter
2764 - fixup getaddrinfo failure handling for remote control port.
2765 - added L.ROOT-SERVERS.NET. AAAA 2001:500:3::42 to builtin root hints.
2766 - fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
2767 - comm_timer_set performs base_set operation after event_add.
2769 18 December 2008: Wouter
2770 - fixed bug reported by Duane Wessels: error in DLV lookup, would make
2771 some zones that had correct DLV keys as insecure.
2772 - follows -rc makedist from ldns changes (no _rc).
2773 - ldns tarball updated with 1.4.1rc for DLV unit test.
2774 - verbose prints about recursion lame detection and server selection.
2775 - fixup BSD port for infra host storage. It hashed wrongly.

2780 - follows ldns makedist.sh. -rc option. autom4te dir removed.
2781 - unbound-control status command.
2782 - extended statistics has a number of ipv6 queries counter.
2783 contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
2785 16 December 2008: Wouter
2786 - follow makedist improvements from ldns, for maintainers prereleases.
2787 - snapshot version uses _ not - to help rpm distinguish the
2790 11 December 2008: Wouter
2791 - better fix for bug #219: use LOG_NDELAY with openlog() call.
2792 Thanks to Tamas Tevesz.
2794 9 December 2008: Wouter
2795 - bug #221 fixed: unbound checkconf checks if key files exist if
2796 remote control is enabled. Also fixed NULL printf when not chrooted.
2797 - iana portlist updated.
2799 3 December 2008: Wouter
2800 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
2801 freezes up unbound if this was compiled without threading, and
2802 was using multiple processes.
2803 - iana portlist updated.
2804 - test for remote control with interprocess communication.
2805 - created command distribution mechanism so that remote control
2806 commands other than 'stats' work on all processes in a nonthreaded
2807 compiled version. dump/load cache work, on the first process.
2808 - fixup remote control local_data addition memory corruption bug.
2810 1 December 2008: Wouter
2811 - SElinux policy files in contrib/selinux for the unbound daemon,
2812 by Paul Wouters and Adam Tkac.

2816 - skip unsupported feature tests on vista/mingw.
2817 - fixup testcode/streamtcp to work on vista/mingw.
2818 - root-hints test checks version of dig required.
2819 - blacklisted servers are polled at a low rate (1%) to see if they
2820 come back up. But not if there is some other working server.
2822 24 November 2008: Wouter
2823 - document that the user of the server daemon needs read privileges
2824 on the keys and certificates generated by unbound-control-setup.
2825 This is different per system or distribution, usually, running the
2826 script under the same username as the server uses suffices.
2827 i.e. sudo -u unbound unbound-control-setup
2828 - testset port to vista/mingw.
2829 - tcp_sigpipe to freebsd port.
2831 21 November 2008: Wouter
2832 - fixed tcp accept, errors were printed when they should not.
2833 - unbound-control-setup.sh removes read/write permissions other
2834 from the keys it creates (as suggested by Dmitriy Demidov).

2838 - add check in rlimit to avoid integer underflow.
2839 - rlimit check with new formula; better estimate for number interfaces
2840 - nicer comments in rlimit check.

2844 19 November 2008: Wouter
2845 - bug #219: fixed so that syslog which delays opening until the first
2846 log line is written, gets a log line while not chroot'ed yet.
2848 18 November 2008: Wouter
2849 - iana portlist updated.
2850 - removed cast in unit test debug print that was not 64bit safe.
2851 - trunk back to 1.1.0; copied to tags 1.1.0 release.
2852 - trunk to has version number 1.1.1 again.
2853 - in 1.1.1; make clean nicer. grammar in manpage.
2855 17 November 2008: Wouter
2856 - theoretical fix for problems reported on mailing list.
2857 If a delegation point has no A but only AAAA and do-ip6 is no,
2858 resolution would fail. Fixed to ask for the A and AAAA records.
2859 It has to ask for both always, so that it can fail quietly, from
2860 TLD perspective, when a zone is only reachable on one transport.
2861 - test for above, only AAAA and doip6 is no. Fix causes A record
2862 for nameserver to be fetched.
2863 - fixup address duplication on cache fillup for delegation points.
2864 - testset updated for new query answer requirements.
2866 14 November 2008: Wouter

2879 12 November 2008: Wouter
2880 - add unbound-control manpage to makedist replace list.
2882 11 November 2008: Wouter
2883 - unit test for negative cache, stress tests the refcounting.
2884 - fix for refcounting error that could cause fptr_wlist fatal exit
2885 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
2886 Attila Nagy for testing).
2887 - nicer comments in cachedump about failed RR to string conversion.

2908 - if query and reply qname overlap, the bytes are skipped not copied.
2909 - fixed file descriptor leak when messages were jostled out that
2910 had outstanding (TCP) replies.
2911 - DNAMEs used from cache have their synthesized CNAMEs initialized
2913 - fixed file descriptor leak for localzone type deny (for TCP).
2914 - fixed memleak at exit for nsec3 negative cached zones.
2915 - fixed memleak for the keyword 'nodefault' when reading config.
2916 - made verbosity of 'edns incapable peer' warning higher, so you
2917 do not get spammed by it.
2918 - caught elusive Bad file descriptor error bug, that would print the
2919 error while unnecessarily try to listen to a closed fd. Fixed.
2921 4 November 2008: Wouter
2922 - fixed -Wwrite-strings warnings that result in better code.
2924 3 November 2008: Wouter

2930 from ldns 1.4.0 (need very latest version).
2931 - updated the included ldns tarball.
2932 - proper detection of SHA256 and SHA512 functions (not just sizes).
2934 23 October 2008: Wouter
2935 - a little more debug info for failure on signer names. prints names.
2937 22 October 2008: Wouter
2938 - CFLAGS are picked up by configure from the environment.
2939 - iana portlist updated.
2940 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
2941 - new stub-prime: yesno option. Default is off, so it does not prime.
2942 can be turned on to get same behaviour as previous unbound release.
2943 - made automated test that checks if builtin root hints are uptodate.
2944 - finished draft-wijngaards-dnsext-resolver-side-mitigation
2945 implementation. The unwanted-reply-threshold can be set.
2946 - fixup so fptr_whitelist test in alloc.c works.
2948 21 October 2008: Wouter
2949 - fix update-anchors.sh, so it does not report different RR order
2950 as an update. Sorts the keys in the file. Updated copyright.
2951 - fixup testbound on windows, the command control pipe doesn't exist.
2952 - skip 08hostlib test on windows, no fork() available.
2953 - made unbound-remote work on windows.
2955 20 October 2008: Wouter
2956 - quench a log message that is debug only.
2957 - iana portlist updated.
2958 - do not query bogus nameservers. It is like nameservers that have
2959 the NS or A or AAAA record bogus are listed as donotquery.
2960 - if server selection is faced with only bad choices, it will
2961 attempt to get more options to be fetched.
2962 - changed bogus-ttl default value from 900 to 60 seconds.
2963 In anticipation that operator caused failures are more likely than
2964 actual attacks at this time. And thus repeated validation helps
2965 the operators get the problem fixed sooner. It makes validation
2966 failures go away sooner (60 seconds after the zone is fixed).
2967 Also it is likely to try different nameserver targets every minute,
2968 so that if a zone is bad on one server but not another, it is
2969 likely to pick up the 'correct' one after a couple minutes,
2970 and if the TTL is big enough that solves validation for the zone.
2971 - fixup unbound-control compilation on windows.
2973 17 October 2008: Wouter
2974 - port Leopard/G5: fixup type conversion size_t/uint32.
2975 please ranlib, stop file without symbols warning.
2976 - harden referral path now also validates the root after priming.
2977 It looks up the root NS authoritatively as well as the root servers
2978 and attemps to validate the entries.
2980 16 October 2008: Wouter
2981 - Fixup negative TTL values appearing (reported by Attila Nagy).
2983 15 October 2008: Wouter
2984 - better documentation for 0x20; remove fallback TODO, it is done.
2985 - harden-referral-path feature includes A, AAAA queries for glue,
2986 as well as very careful NS caching (only when doing NS query).
2987 A, AAAA use the delegation from the NS-query.
2989 14 October 2008: Wouter
2990 - fwd_three.tpkg test was flaky. If the three requests hit the
2991 wrong threads by chance (or bad OS) then the test would fail.
2992 Made less flaky by increasing number of retries.
2993 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
2994 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
2995 Which includes the ldns_dname_absolute fix.
2996 - fwd_three test remains flaky now that unbound does not stop
2997 listening when full. Thus, removed timeout problem.
2998 It may be serviced by three threads, or maybe by one.
2999 Mostly only useful for lock-check testing now.
3001 13 October 2008: Wouter
3002 - fixed recursion servers deployed as authoritative detection, so
3003 that as a last resort, a +RD query is sent there to get the
3005 - iana port list update.
3006 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
3008 10 October 2008: Wouter

3031 can restart unbound exactly when needed.
3033 30 September 2008: Wouter
3034 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
3035 - tests for sha256 support and downgrade resistance.

3039 Like when running NSD to host a local zone, on the same machine.
3040 The noprime feature. manpages more explanation. Added a test for it.
3041 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
3043 29 September 2008: Wouter
3044 - EDNS lameness detection, if EDNS packets are dropped this is

3143 and these are only visible by using the -d commandline flag.
3145 27 August 2008: Wouter
3146 - daemon(3) is causing problems for people. Reverting the patch.
3147 bug#200, and 199 and 203 contain sideline discussion on it.

3308 - skip tests that need signals when testing on mingw.
3310 18 June 2008: Wouter

3382 - bug 179: same fix as 177.
3383 - bug 185: --disable-shared not passed along to ldns included with
3384 unbound. Fixed so that configure parameters are passed to the
3385 subdir configure script.
3386 fixed that ./libtool is used always, you can still override
3387 manually with ./configure libtool=mylibtool or set $libtool in
3389 - update of the ldns tarball to current ldns svn version (fix 181).
3390 - bug 184: -r option for unbound-host, read resolv.conf for
3391 forwarder. (Note that forwarder must support DNSSEC for validation
3396 - test for sys/wait.h

3443 - contrib files unbound.spec and unbound.init, builds working RPM
3444 on FC7 Linux, a chrooted caching resolver, and libunbound.
3445 - iana ports update.
3447 24 April 2008: Wouter
3448 - chroot checks improved. working directory relative to chroot.
3449 checks if config file path is inside chroot. Documentation on it.
3450 - nicer example.conf text.

3478 - example.conf values changed to /usr/local/etc/unbound
3480 - DSA signatures: unbound is compatible with both encodings found.
3481 It will detect and convert when necessary.
3483 14 April 2008: Wouter
3484 - got update for parseunbound.pl statistics script from Kai Storbeck.
3485 - tpkg tests for udp wait list.
3486 - documented 0x20 status.
3487 - fixup chroot and checkconf, it is much smarter now.
3488 - fixup DSA EVP signature decoding. Solution that Jelte found copied.
3489 - and check first sig byte for the encoding type.
3491 11 April 2008: Wouter
3492 - random port selection out of the configged ports.
3493 - fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
3494 - removed base_port.
3495 - created 256-port ephemeral space for the OS, 59802 available.
3496 - fixup consistency of port_if out array during heavy use.
3498 10 April 2008: Wouter
3499 - --with-libevent works with latest libevent 1.4.99-trunk.
3500 - added log file statistics perl script to contrib.
3501 - automatic iana ports update from makefile. 60058 available.
3503 9 April 2008: Wouter
3504 - configure can detect libev(from its build directory) when passed
3505 --with-libevent=/home/wouter/libev-3.2
3506 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
3507 - unused commpoints not listed in epoll list.
3508 - statistics-cumulative option so that the values are not reset.
3509 - config creates array of available ports, 61841 available,
3510 it excludes <1024 and iana assigned numbers.
3511 config statements to modify the available port numbers.
3513 8 April 2008: Wouter
3514 - unbound tries to set the ulimit fds when started as server.
3515 if that does not work, it will scale back its requirements.
3517 27 March 2008: Wouter
3518 - documented /dev/random symlink from chrootdir as FAQ entry.
3520 26 March 2008: Wouter
3521 - implemented AD bit signaling. If a query sets AD bit (but not DO)
3522 then the AD bit is set in the reply if the answer validated.
3523 Without including DNSSEC signatures. Useful if you have a trusted
3524 path from the client to the resolver. Follows dnssec-updates draft.
3526 25 March 2008: Wouter
3527 - implemented check that for NXDOMAIN and NOERROR answers a query
3528 section must be present in the reply (by the scrubber). And it must
3529 be equal to the question sent, at least lowercase folded.
3530 Previously this feature happened because the cache code refused
3531 to store such messages. However blocking by the scrubber makes
3532 sure nothing gets into the RRset cache. Also, this looks like a
3533 timeout (instead of an allocation failure) and this retries are
3534 done (which is useful in a spoofing situation).
3535 - RTT banding. Band size 400 msec, this makes band around zero (fast)
3536 include unknown servers. This makes unbound explore unknown servers.
3538 7 March 2008: Wouter
3539 - -C config feature for harvest program.
3540 - harvest handles CNAMEs too.
3542 5 March 2008: Wouter
3543 - patch from Hugo Koji Kobayashi for iterator logs spelling.
3545 4 March 2008: Wouter
3546 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
3547 of a cname trust chain is lower; not full answer_AA.
3548 - test for this fix.
3549 - default config file location is /usr/local/etc/unbound.
3550 Thus prefix is used to determine the location. This is also the
3551 chroot and pidfile default location.
3553 3 March 2008: Wouter
3554 - Create 0.10 svn tag.
3555 - 0.11 version in trunk.
3556 - indentation nicer.
3558 29 February 2008: Wouter
3559 - documentation update.
3560 - fixup port to Solaris of perf test tool.
3561 - updated ldns-tarball with decl-after-statement fixes.
3563 28 February 2008: Wouter

3565 - libunbound returns the answer packet in full.
3566 - snprintf compat update.
3567 - harvest performs lookup.
3568 - ldns-tarball update with fix for ldns_dname_label.
3569 - installs to sbin by default.
3570 - install all manual pages (unbound-host and libunbound too).
3572 27 February 2008: Wouter
3573 - option to use caps for id randomness.
3574 - config file option use-caps-for-id: yes
3575 - harvest debug tool
3577 26 February 2008: Wouter
3578 - delay utility delays TCP as well. If the server that is forwarded
3579 to has a TCP error, the delay utility closes the connection.
3580 - delay does REUSE_ADDR, and can handle a server that closes its end.
3581 - answers use casing from query.
3583 25 February 2008: Wouter
3584 - delay utility works. Gets decent thoughput too (>20000).
3586 22 February 2008: Wouter
3587 - +2% for recursions, if identical queries (except for destination
3588 and query ID) in the reply list, avoid re-encoding the answer.
3589 - removed TODO items for optimizations that do not show up in
3591 - default is now minievent - not libevent. As its faster and
3592 not needed for regular installs, only for very large port ranges.
3593 - loop check different speedup pkt-dname-reading, 1% faster for
3594 nocache-recursion check.
3595 - less hashing during msg parse, 4% for recursion.
3596 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
3597 - some speed results noted:
3598 optimization resulted in +40% for recursion (cache miss) and
3599 +70 to +80 for cache hits, and +96% for version.bind.
3600 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
3601 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
3602 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
3603 So, unbound can be about equal qps to NSD in cache hits.
3604 And about 3.4x faster than BIND in cache performance.
3605 - delay utility for testing.
3607 21 February 2008: Wouter
3608 - speedup of root-delegation message encoding by 15%.
3609 - minor speedup of compress tree_lookup, maybe 1%.
3610 - speedup of dname_lab_cmp and memlowercmp - the top functions in
3611 profiler output, maybe a couple percent when it matters.
3613 20 February 2008: Wouter
3614 - setup speec_cache for need-ldns-testns in dotests.
3615 - check number of queued replies on incoming queries to avoid overload
3617 - fptr whitelist checks are not disabled in optimize mode.
3618 - do-daemonize config file option.
3619 - minievent time share initializes time at start.
3620 - updated testdata for nsec3 new algorithm numbers (6, 7).
3621 - small performance test of packet encoding (root delegation).
3623 19 February 2008: Wouter
3624 - applied patch to unbound-host man page from Jan-Piet Mens.
3625 - fix donotquery-localhost: yes default (it erroneously was switched
3627 - time is only gotten once and the value is shared across unbound.
3628 - unittest cleans up crypto, so that it has no memory leaks.
3629 - mini_event shares the time value with unbound this results in
3630 +3% speed for cache responses and +9% for recursions.
3631 - ldns tarball update with new NSEC3 sign code numbers.
3632 - perform several reads per UDP operation. This improves performance
3633 in DoS conditions, and costs very little in normal conditions.
3634 improves cache response +50%, and recursions +10%.
3635 - modified asynclook test. because the callback from async is not
3636 in any sort of lock (and thus can use all library functions freely),
3637 this causes a tiny race condition window when the last lock is
3638 released for a callback and a new cancel() for that callback.
3639 The only way to remove this is by putting callbacks into some
3640 lock window. I'd rather have the small possibility of a callback
3641 for a cancelled function then no use of library functions in
3642 callbacks. Could be possible to only outlaw process(), wait(),
3643 cancel() from callbacks, by adding another lock, but I'd rather not.
3645 18 February 2008: Wouter
3646 - patch to unbound-host from Jan-Piet Mens.
3647 - unbound host prints errors if fails to configure context.
3648 - fixup perf to resend faster, so that long waiting requests do
3649 not hold up the queue, they become lost packets or SERVFAILs,
3650 or can be sent a little while later (i.e. processing time may
3651 take long, but throughput has to be high).
3652 - fixup iterator operating in no cache conditions (RD flag unset
3654 - streamlined code for RD flag setting.
3655 - profiled code and changed dname compares to be faster.
3656 The speedup is about +3% to +8% (depending on the test).
3657 - minievent tests for eintr and eagain.
3659 15 February 2008: Wouter
3660 - added FreeBSD rc.d script to contrib.
3661 - --prefix option for configure also changes directory: pidfile:
3662 and chroot: defaults in config file.
3663 - added cache speed test, for cache size OK and cache too small.
3665 14 February 2008: Wouter
3666 - start without a config file (will complain, but start with
3668 - perf test program works.
3670 13 February 2008: Wouter

3690 - unbound replies to multiple TCP queries on a TCP channel.
3691 - fixup misclassification of root referral with NS in answer
3692 when validating a nonrec query.
3694 - layout of manpages, spelling fix in header, manpages process by
3695 makedist, list asynclook and tcpstream tests as ldns-testns
3698 7 February 2008: Wouter
3699 - moved up all current level 2 to be level 3. And 3 to 4.
3700 to make room for new debug level 2 for detailed information
3702 - verbosity level 2. Describes recursion and validation.
3703 - cleaner configure script and fixes for libevent solaris.
3704 - signedness for log output memory sizes in high verbosity.
3706 6 February 2008: Wouter
3707 - clearer explanation of threading configure options.
3708 - fixup asynclook test for nothreading (it creates only one process
3709 to do the extended test).
3710 - changed name of ub_val_result_free to ub_val_resolve_free.
3711 - removes warning message during library linking, renamed
3712 libunbound/unbound.c -> libunbound.c and worker to libworker.
3713 - fallback without EDNS if result is NOTIMPL as well as on FORMERR.
3715 5 February 2008: Wouter

3719 - fixup Makefile strip command and libunbound docs typo.
3721 31 January 2008: Wouter
3722 - bg thread/process reads and writes the pipe nonblocking all the time
3723 so that even if the pipe is buffered or so, the bg thread does not
3724 block, and services both pipes and queries.
3726 30 January 2008: Wouter
3727 - check trailing / on chrootdir in checkconf.
3728 - check if root hints and anchor files are in chrootdir.
3729 - no route to host tcp error is verbosity level 2.
3730 - removed unused send_reply_iov. and its configure check.
3731 - added prints of 'remote address is 1.2.3.4 port 53' to errors
3732 from netevent; the basic socket errors.
3734 28 January 2008: Wouter
3735 - fixup uninit use of buffer by libunbound (query id, flags) for
3737 - fixup uninit warning from random.c; also seems to fix sporadic
3738 sigFPE coming out of openssl.
3739 - made openssl entropy warning more silent for library use. Needs
3741 - fixup forgotten locks for rbtree_searches on ctx->query tree.

3745 - protect config access in libworker_setup().
3746 - libevent doesn't like comm_base_exit outside of runloop.

3753 really fast answers that beat the cancel).
3754 - please doxygen, put doxygen comment in one place.
3755 - asynclook -b blocking mode and test.
3756 - refactor asynclook, nicer code.
3757 - fixup race problems from opensll in rand init from library, with
3758 a mutex around the rand init.
3759 - fix pass async_id=NULL to _async resolve().
3760 - rewrote _wait() routine, so that it is threadsafe.
3761 - cancelation is threadsafe.
3762 - asynclook extended test in tpkg.
3763 - fixed two races where forked bg process waits for (somehow shared?)
3764 locks, so does not service the query pipe on the bg side.
3765 Now those locks are only held for fg_threads and for bg_as_a_thread.
3767 24 January 2008: Wouter
3768 - tested the cancel() function.
3769 - asynclook -c (cancel) feature.

3777 23 January 2008: Wouter
3778 - removed debug prints from if-auto, verb-algo enables some.
3779 - libunbound QUIT setup, remove memory leaks, when using threads
3780 will share memory for passing results instead of writing it over
3781 the pipe, only writes ID number over the pipe (towards the handler
3782 thread that does process() ).
3784 22 January 2008: Wouter
3785 - library code for async in libunbound/unbound.c.
3786 - fix link testbound.
3787 - fixup exit bug in mini_event.
3788 - background worker query enter and result functions.
3789 - bg query test application asynclook, it looks up multiple
3790 hostaddresses (A records) at the same time.
3792 21 January 2008: Wouter
3793 - libworker work, netevent raw commpoints, write_msg, serialize.
3795 18 January 2008: Wouter
3796 - touch up of manpage for libunbound.
3797 - support for IP_RECVDSTADDR (for *BSD ip4).
3798 - fix for BSD, do not use ip4to6 mapping, make two sockets, once
3799 ip6 and once ip4, uses socket options.
3800 - goodbye ip4to6 mapping.
3801 - update ldns-testpkts with latest version from ldns-trunk.
3802 - updated makedist for relative ldns pathnames.

3812 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
3814 16 January 2008: Wouter
3815 - incoming queries to the server with TC bit on are replied FORMERR.
3816 - interface-automatic replied the wrong source address on localhost
3817 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
3818 to use ifnum=-1 to mean 'no interface, use kernel route'.
3820 15 January 2008: Wouter
3821 - interface-automatic feature. experimental. Nice for anycast.
3822 - tpkg test for ip6 ancillary data.
3823 - removed debug prints.
3824 - porting experience, define for Solaris, test refined for BSD
3825 compatibility. The feature probably will not work on OpenBSD.
3826 - makedist fixup for ldns-src in build-dir.
3828 14 January 2008: Wouter
3829 - in no debug sets NDEBUG to remove asserts.
3830 - configure --enable-debug is needed for dependency generation
3831 for assertions and for compiler warnings.
3832 - ldns.tgz updated with ldns-trunk (where buffer.h is updated).
3833 - fix lint, unit test in optimize mode.
3834 - default access control allows ::ffff:127.0.0.1 v6mapped localhost.
3836 11 January 2008: Wouter
3837 - man page, warning removed.
3838 - added text describing the use of stub zones for private zones.
3839 - checkconf tests for bad hostnames (IP address), and for doubled
3841 - memory sizes can be given with 'k', 'Kb', or M or G appended.
3843 10 January 2008: Wouter
3844 - typo in example.conf.
3845 - made using ldns-src that is included the package more portable
3846 by linking with .lo instead of .o files in the ldns package.
3847 - nicer do-ip6: yes/no documentation.
3848 - nicer linking of libevent .o files.
3849 - man pages render correctly on solaris.
3851 9 January 2008: Wouter
3852 - fixup openssl RAND problem, when the system is not configured to
3853 give entropy, and the rng needs to be seeded.
3855 8 January 2008: Wouter
3856 - print median and quartiles with extensive logging.
3858 4 January 2008: Wouter
3859 - document misconfiguration in private network.
3861 2 January 2008: Wouter
3862 - fixup typo in requirements.
3863 - document that 'refused' is a better choice than 'drop' for
3864 the access control list, as refused will stop retries.
3866 7 December 2007: Wouter
3867 - unbound-host has a -d option to show what happens. This can help
3868 with debugging (why do I get this answer).
3869 - fixup CNAME handling, on nodata, sets and display canonname.
3870 - dot removed from CNAME display.
3871 - respect -v for NXDOMAINs.

3874 - fixup bogus handling.
3875 - dependencies and lint for unbound-host.
3877 6 December 2007: Wouter
3878 - library resolution works in foreground mode, unbound-host app
3880 - unbound-host prints rdata using ldns.
3881 - unbound-host accepts trust anchors, and prints validation
3882 information when you give -v.
3884 5 December 2007: Wouter
3885 - locking in context_new() inside the function.
3886 - setup of libworker.
3888 4 December 2007: Wouter
3889 - minor Makefile fixup.
3890 - moved module-stack code out of daemon/daemon into services/modstack,
3891 preparing for code-reuse.
3892 - move context into own header file.
3893 - context query structure.
3894 - removed unused variable pwd from checkconf.
3895 - removed unused assignment from outside netw.
3896 - check timeval length of string.
3897 - fixup error in val_utils getsigner.
3898 - fixup same (*var) error in netblocktostr.
3899 - fixup memleak on parse error in localzone.
3900 - fixup memleak on packet parse error.
3901 - put ; after union in parser.y.
3902 - small hardening in iter_operate against iq==NULL.
3903 - hardening, if error reply with rcode=0 (noerror) send servfail.
3904 - fixup same (*var) error in find_rrset in msgparse, was harmless.
3905 - check return value of evtimer_add().
3906 - fixup lockorder in lruhash_reclaim(), building up a list of locked
3907 entries one at a time. Instead they are removed and unlocked.
3908 - fptr_wlist for markdelfunc.
3909 - removed is_locked param from lruhash delkeyfunc.
3910 - moved bin_unlock during bin_split purely to please.
3912 3 December 2007: Wouter
3913 - changed checkconf/ to smallapp/ to make room for more support tools.
3914 (such as unbound-host).
3915 - install dirs created with -m 755 because they need to be accessible.
3916 - library extensive featurelist added to TODO.
3917 - please doxygen, lint.
3918 - library test application, with basic functionality.
3919 - fix for building in a subdirectory.
3920 - link lib fix for Leopard.
3922 30 November 2007: Wouter
3923 - makefile that creates libunbound.la, basic file or libunbound.a
3924 when creating static executables (no libtool).
3927 29 November 2007: Wouter
3928 - 0.9 public API start.
3930 28 November 2007: Wouter
3931 - Changeup plan for 0.8 - no complication needed, a simple solution
3932 has been chosen for authoritative features.
3933 - you can use single quotes in the config file, so it is possible
3934 to specify TXT records in local data.
3935 - fixup small memory problem in implicit transparent zone creation.
3936 - test for implicit zone creation and multiple RR RRsets local data.
3937 - local-zone nodefault test.
3938 - show testbound testlist on commit.
3939 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
3940 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
3942 - nicer verbosity: 0 and 1 levels.
3943 - lower nonRDquery chance of eliciting wrongly typed validation
3944 requiring message from the cache.
3945 - fix for nonRDquery validation typing; nodata is detected when
3946 SOA record in auth section (all validation-requiring nodata messages
3947 have a SOA record in authority, so this is OK for the validator),
3948 and NS record is needed to be a referral.
3949 - duplicate checking when adding NSECs for a CNAME, and test.
3950 - created svn tag 0.8, after completing testbed tests.
3952 27 November 2007: Wouter
3953 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
3954 - set size of msgparse lookup table to 32, from 1024, so that its size
3955 is below the 2048 regional large size threshold, and does not cause
3956 a call to malloc when a message is parsed.
3957 - update of memstats tool to print number of allocation calls.
3958 This is what is taking time (not space) and indicates the avg size
3959 of the allocations as well. region_alloc stat is removed.
3961 22 November 2007: Wouter
3962 - noted EDNS in-the-middle dropping trouble as a TODO.
3963 At this point theoretical, no user trouble has been reported.
3964 - added all default AS112 zones.
3965 - answers from local zone content.
3966 * positive answer, the rrset in question
3967 * nodata answer (exist, but not that type).
3968 * nxdomain answer (domain does not exist).
3969 * empty-nonterminal answer.
3970 * But not: wildcard, nsec, referral, rrsig, cname/dname,
3971 or additional section processing, NS put in auth.
3972 - test for correct working of static and transparent and couple
3973 of important defaults (localhost, as112, reverses).
3974 Also checks deny and refuse settings.
3975 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
3977 21 November 2007: Wouter
3978 - local zone internal data setup.
3980 20 November 2007: Wouter
3981 - 0.8 - str2list config support for double string config options.
3982 - local-zone and local-data options, config storage and documentation.
3984 19 November 2007: Wouter
3985 - do not downcase NSEC and RRSIG for verification. Follows
3986 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
3987 - fixup leaking unbound daemons at end of tests.
3988 - README file updated.
3989 - nice libevent not found error.
3990 - README talks about gnu make.
3991 - 0.8: unit test for addr_mask and fixups for it.
3992 and unit test for addr_in_common().
3993 - 0.8: access-control config file element.
3994 and unit test rpl replay file.
3995 - 0.8: fixup address reporting from netevent.
3997 16 November 2007: Wouter
3998 - privilege separation is not needed in unbound at this time.
3999 TODO item marked as such.
4000 - created beta-0.7 branch for support.
4001 - tagged 0.7 for beta release.
4002 - moved trunk to 0.8 for 0.8(auth features) development.
4003 - 0.8: access control list setup.
4005 15 November 2007: Wouter
4006 - review fixups from Jelte.
4008 14 November 2007: Wouter
4009 - testbed script does not recreate configure, since its in svn now.
4010 - fixup checkconf test so that it does not test
4011 /etc/unbound/unbound.conf.
4014 13 November 2007: Wouter
4015 - remove debug print.
4016 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
4018 12 November 2007: Wouter
4019 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
4021 - bugreports to unbound-bugs@nlnetlabs.nl
4022 - fixup testbound so it exits cleanly.
4023 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
4025 9 November 2007: Wouter
4026 - took ldns snapshot in repo.
4027 - default config file is /etc/unbound/unbound.conf.
4028 If it doesn't exist, it is installed with the doc/example.conf file.
4029 The file is not deleted on uninstall.
4030 - default listening is not all, but localhost interfaces.
4032 8 November 2007: Wouter
4033 - Fixup chroot and drop user privileges.
4034 - new L root ip address in default hints.
4036 1 November 2007: Wouter
4037 - Fixup of crash on reload, due to anchors in env not NULLed after
4038 dealloc during deinit.
4039 - Fixup of chroot call. Happens after privileges are dropped, so
4040 that checking the passwd entry still works.
4041 - minor touch up of clear() hashtable function.
4042 - VERB_DETAIL prints out what chdir, username, chroot is being done.
4043 - when id numbers run out, caches are cleared, as in design notes.
4044 Tested with a mock setup with very few bits in id, it worked.
4045 - harden-dnssec-stripped: yes is now default. It insists on dnssec
4046 data for trust anchors. Included tests for the feature.
4048 31 October 2007: Wouter
4049 - cache-max-ttl config option.
4050 - building outside sourcedir works again.
4051 - defaults more secure:
4053 chroot: "/etc/unbound"
4054 The operator can override them to be less secure ("") if necessary.
4055 - fix horrible oversight in sorting rrset references in a message,
4056 sort per reference key pointer, not on referencepointer itself.
4057 - pidfile: "/etc/unbound/unbound.pid" is now the default.
4058 - tests changed to reflect the updated default.
4059 - created hashtable clear() function that respects locks.
4061 30 October 2007: Wouter
4062 - fixup assertion failure that relied on compressed names to be
4063 smaller than uncompressed names. A packet from comrite.com was seen
4064 to be compressed to a larger size. Added it as unit test.
4065 - quieter logging at low verbosity level for common tcp messages.
4066 - no greedy TTL update.
4068 23 October 2007: Wouter
4069 - fixup (grand-)parent problem for dnssec-lameness detection.
4070 - fixup tests to do additional section processing for lame replies,
4071 since the detection needs that.
4072 - no longer trust in query section in reply during dnssec lame detect.
4073 - dnssec lameness does not make the server never ever queried, but
4074 non-preferred. If no other servers exist or answer, the dnssec lame
4075 server is used; the fastest dnssec lame server is chosen.
4076 - added test then when trust anchor cannot be primed (nodata), the
4077 insecure mode from unbound works.
4078 - Fixup max queries per thread, any more are dropped.
4080 22 October 2007: Wouter
4081 - added donotquerylocalhost config option. Can be turned off for
4083 - ISO C compat changes.
4084 - detect RA-no-AA lameness, as LAME.
4085 - DNSSEC-lameness detection, as LAME.
4086 See notes in requirements.txt for choices made.
4087 - tests for lameness detection.
4088 - added all to make test target; need unbound for fwd tests.
4089 - testbound does not pollute /etc/unbound.
4091 19 October 2007: Wouter
4092 - added configure (and its files) to svn, so that the trunk is easier
4093 to use. ./configure, config.guess, config.sub, ltmain.sh,
4095 - added yacc/lex generated files, util/configlexer.c,
4096 util/configparser.c util/configparser.h, to svn.
4097 - without lex no attempt to use it.
4098 - unsecure response validation collated into one block.
4099 - remove warning about const cast of cfgfile name.
4100 - outgoing-interfaces can be different from service interfaces.
4101 - ldns-src configure is done during unbound configure and
4102 ldns-src make is done during unbound make, and so inherits the
4103 make arguments from the unbound make invocation.
4104 - nicer error when libevent problem causes instant exit on signal.
4105 - read root hints from a root hint file (like BIND does).
4107 18 October 2007: Wouter
4108 - addresses are logged with errors.
4109 - fixup testcode fake event to remove pending before callback
4110 since the callback may create new pending items.
4111 - tests updated because retries are now in iterator module.
4112 - ldns-testpkts code is checked for differences between unbound
4113 and ldns by makedist.sh.
4114 - ldns trunk from today added in svn repo for fallback in case
4115 no ldns is installed on the system.
4116 make download_ldns refreshes the tarball with ldns svn trunk.
4117 - ldns-src.tar.gz is used if no ldns is found on the system, and
4118 statically linked into unbound.
4119 - start of regional allocator code.
4120 - regional uses less memory and variables, simplified code.
4121 - remove of region-allocator.
4122 - alloc cache keeps a cache of recently released regional blocks,
4124 - make unit test cleanly free memory.
4126 17 October 2007: Wouter
4127 - fixup another cycle detect and ns-addr timeout resolution bug.
4128 This time by refusing delegations from the cache without addresses
4129 when resolving a mandatory-glue nameserver-address for that zone.
4130 We're going to have to ask a TLD server anyway; might as well be
4131 the TLD server for this name. And this resolves a lot of cases where
4132 the other nameserver names lead to cycles or are not available.
4133 - changed random generator from random(3) clone to arc4random wrapped
4134 for thread safety. The random generator is initialised with
4135 entropy from the system.
4136 - fix crash where failure to prime DNSKEY tried to print null pointer
4138 - removed some debug prints, only verb_algo (4) enables them.
4139 - fixup test; new random generator took new paths; such as one
4140 where no scripted answer was available.
4141 - mark insecure RRs as insecure.
4142 - fixup removal of nonsecure items from the additional.
4143 - reduced timeout values to more realistic, 376 msec (262 msec has
4144 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
4145 - server selection failover to next server after timeout (376 msec).
4147 16 October 2007: Wouter
4148 - no malloc in log_hex.
4149 - assertions around system calls.
4150 - protect against gethostname without ending zero.
4151 - ntop output is null terminated by unbound.
4152 - pidfile content null termination
4153 - various snprintf use sizeof(stringbuf) instead of fixed constant.
4154 - changed loopdetect % 8 with & 0x7 since % can become negative for
4155 weird negative input and particular interpretation of integer math.
4156 - dname_pkt_copy checks length of result, to protect result buffers.
4157 prints an error, this should not happen. Bad strings should have
4158 been rejected earlier in the program.
4159 - remove a size_t underflow from msgreply size func.
4161 15 October 2007: Wouter
4163 - fix IP6 TCP, wrong definition check. With test package.
4164 - fixup the fact that the query section was not compressed to,
4165 the code was there but was called by value instead of by reference.
4166 And test for the case, uses xxd and nc.
4167 - more portable ip6 check for sockaddr types.
4169 8 October 2007: Wouter
4170 - --disable-rpath option in configure for 64bit systems with
4171 several dynamic lib dirs.
4173 7 October 2007: Wouter
4174 - fixup tests for no AD bit in non-DO queries.
4175 - test that makes sure AD bit is not set on non-DO query.
4177 6 October 2007: Wouter
4178 - removed logfile open early. It did not have the proper permissions;
4179 it was opened as root instead of the user. And we cannot change user
4180 id yet, since chroot and bind ports need to be done.
4181 - callback checks for event callbacks done from mini_event. Because
4182 of deletions cannot do this from netevent. This means when using
4183 libevent the protection does not work on event-callbacks.
4184 - fixup too small reply (did not zero counts).
4185 - fixup reply no longer AD bit when query without DO bit.
4187 5 October 2007: Wouter
4188 - function pointer whitelist.
4190 4 October 2007: Wouter
4191 - overwrite sensitive random seed value after use.
4192 - switch to logfile very soon if not -d (console attached).
4193 - error messages do not reveal the trustanchor contents.
4194 - start work on function pointer whitelists.
4196 3 October 2007: Wouter
4197 - fix for multiple empty nonterminals, after multiple DSes in the
4199 - mesh checks if modules are looping, and stops them.
4200 - refetch with CNAMEd nameserver address regression test added.
4201 - fixup line count bug in testcode, so testbound prints correct line
4202 number with parse errors.
4203 - unit test for multiple ENT case.
4204 - fix for cname out of validated unsec zone.
4205 - fixup nasty id=0 reuse. Also added assertions to detect its
4206 return (the assertion catches in the existing test cases).
4208 1 October 2007: Wouter
4209 - skip F77, CXX, objC tests in configure step.
4210 - fixup crash in refetch glue after a CNAME.
4211 and protection against similar failures (with error print).
4213 28 September 2007: Wouter
4214 - test case for unbound-checkconf, fixed so it also checks the
4215 interface: statements.
4217 26 September 2007: Wouter
4218 - SIGHUP will reopen the log file.
4219 - Option to log to syslog.
4220 - please lint, fixup tests (that went to syslog on open, oops).
4221 - config check program.
4223 25 September 2007: Wouter
4224 - tests for NSEC3. Fixup bitmap checks for NSEC3.
4225 - positive ANY response needs to check if wildcard expansion, and
4226 check that original data did not exist.
4227 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
4228 delegation, for abuse of child zone apex nsec3.
4229 - create 0.5 release tag.
4231 24 September 2007: Wouter
4232 - do not make test programs by default.
4233 - But 'make test' will perform all of the tests.
4234 - Advertise builtin select libevent alternative when no libevent
4236 - signit can generate NSEC3 hashes, for generating tests.
4237 - multiple nsec3 paramaters in message test.
4238 - too high nsec3 iterations becomes insecure test.
4240 21 September 2007: Wouter
4241 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
4242 - fixup testcode lock safety (port FreeBSD).
4243 - removes subscript has type char warnings (port Solaris 9).
4244 - fixup of field with format type to int (port MacOS/X intel).
4245 - added test for infinite loop case in nonRD answer validation.
4246 It was a more general problem, but hard to reproduce. When an
4247 unsigned rrset is being validated and the key fetched, the DS
4248 sequence is followed, but if the final name has no DS, then no
4249 proof is possible - the signature has been stripped off.
4251 20 September 2007: Wouter
4252 - fixup and test for NSEC wildcard with empty nonterminals.
4253 - makedist.sh fixup for svn info.
4254 - acl features request in plan.
4255 - improved DS empty nonterminal handling.
4256 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
4257 proof anyway, which succeeds in ANS failure case.
4258 - striplab protection in case it becomes -1.
4259 - plans for static and blacklist config.
4261 19 September 2007: Wouter
4262 - comments about non-packed usage.
4263 - plan for overload support in 0.6.
4264 - added testbound tests for a failed resolution from the logs
4265 and for failed prime when missing glue.
4266 - fixup so useless delegation points are not returned from the
4267 cache. Also the safety belt is used if priming fails to complete.
4268 - fixup NSEC rdata not to be lowercased, bind compat.
4270 18 September 2007: Wouter
4271 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
4272 - validator prints subtype classification for debug.
4274 17 September 2007: Wouter
4275 - NSEC3 hash cache unit test.
4276 - validator nsec3 nameerror test.
4278 14 September 2007: Wouter
4279 - nsec3 nodata proof, nods proof, wildcard proof.
4280 - nsec3 support for cname chain ending in noerror or nodata.
4281 - validator calls nsec3 proof routines if no NSECs prove anything.
4282 - fixup iterator bug where it stored the answer to a cname under
4283 the wrong qname into the cache. When prepending the cnames, the
4284 qname has to be reset to the original qname.
4286 13 September 2007: Wouter
4287 - nsec3 find matching and covering, ce proof, prove namerror msg.
4289 12 September 2007: Wouter
4290 - fixup of manual page warnings, like for NSD bugreport.
4291 - nsec3 work, config, max iterations, filter, and hash cache.
4293 6 September 2007: Wouter
4294 - fixup to find libevent on mac port install.
4295 - fixup size_t vs unsigned portability in validator/sigcrypt.
4296 - please compiler on different platforms, for unreachable code.
4298 - pthread_rwlock type is optional, in case of old pthread libs.
4300 5 September 2007: Wouter
4301 - cname, name error validator tests.
4302 - logging of qtype ANY works.
4303 - ANY type answers get RRSIG in answer section of replies (but not
4304 in other sections, unless DO bit is on).
4305 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
4306 - DS and noDS referral validation test.
4307 - if you configure many trust anchors, parent trust anchors can
4308 securely deny existance of child trust anchors, if validated.
4309 - not all *.name NSECs are present because a wildcard was matched,
4310 and *.name NSECs can prove nodata for empty nonterminals.
4311 Also, for wildcard name NSECs, check they are not from the parent
4312 zone (for wildcarded zone cuts), and check absence of CNAME bit,
4314 - configure option for memory allocation debugging.
4315 - port configure option for memory allocation to solaris10.
4317 4 September 2007: Wouter
4318 - fixup of Leakage warning when serviced queries processed multiple
4319 callbacks for the same query from the same server.
4320 - testbound removes config file from /tmp on failed exit.
4321 - fixup for referral cleanup of the additional section.
4322 - tests for cname, referral validation.
4323 - neater testbound tpkg output.
4324 - DNAMEs no longer match their apex when synthesized from the cache.
4325 - find correct signer name for DNAME responses.
4326 - wildcarded DNAME test and fixup code to detect.
4327 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
4328 So that wildcarded CNAMEs get their NSEC with them to the answer.
4329 - test for a CNAME to a DNAME to a CNAME to an answer, all from
4330 different domains, for key fetching and signature checking of
4333 3 September 2007: Wouter
4334 - Fixed error in iterator that would cause assertion failure in
4335 validator. CNAME to a NXDOMAIN response was collated into a response
4336 with both a CNAME and the NXDOMAIN rcode. Added a test that the
4337 rcode is changed to NOERROR (because of the CNAME).
4338 - timeout on tcp does not lead to spurious leakage detect.
4339 - account memory for name of lame zones, so that memory leakages does
4340 not show lame cache growth as a leakage growth.
4341 - config setting for lameness cache expressed in bytes, instead of
4343 - tool too summarize allocations per code line.
4345 31 August 2007: Wouter
4346 - can read bind trusted-keys { ... }; files, in a compatibility mode.
4347 - iterator should not detach target queries that it still could need.
4348 the protection against multiple outstanding queries is moved to a
4349 current_query num check.
4350 - validator nodata, positive, referral tests.
4351 - dname print can print '*' wildcard.
4353 30 August 2007: Wouter
4354 - fixup override date config option.
4355 - config options to control memory usage.
4356 - caught bad free of un-alloced data in worker_send error case.
4357 - memory accounting for key cache (trust anchors and temporary cache).
4358 - memory accounting fixup for outside network tcp pending waits.
4359 - memory accounting fixup for outside network tcp callbacks.
4360 - memory accounting for iterator fixed storage.
4361 - key cache size and slabs config options.
4362 - lib crypto cleanups at exit.
4364 29 August 2007: Wouter
4365 - test tool to sign rrsets for testing validator with.
4366 - added RSA and DSA test keys, public and private pairs, 512 bits.
4367 - default configuration is with validation enabled.
4368 Only a trust-anchor needs to be configured for DNSSEC to work.
4369 - do not convert to DER for DSA signature verification.
4370 - validator replay test file, for a DS to DNSKEY DSA key prime and
4373 28 August 2007: Wouter
4374 - removed double use for udp buffers, that could fail,
4375 instead performs a malloc to do the backup.
4376 - validator validates referral messages, by validating all the rrsets
4377 and stores the rrsets in the cache. Further referral (nonRD queries)
4378 replies are made from the rrset cache directly. Unless unchecked
4379 rrsets are encountered, there are then validated.
4380 - enforce that signing is done by a parent domain (or same domain).
4381 - adjust TTL downwards if rrset TTL bigger than signature allows.
4382 - permissive mode feature, sets AD bit for secure, but bogus does
4383 not give servfail (bogus is changed into indeterminate).
4384 - optimization of rrset verification. rr canonical sorting is reused,
4385 for the same rrset. canonical rrset image in buffer is reused for
4387 - if the rrset is too big (64k exactly + large owner name) the
4388 canonicalization routine will fail if it does not fit in buffer.
4389 - faster verification for large sigsets.
4390 - verb_detail mode reports validation failures, but not the entire
4391 algorithm for validation. Key prime failures are reported as
4394 27 August 2007: Wouter
4395 - do not garble the edns if a cache answer fails.
4396 - answer norecursive from cache if possible.
4397 - honor clean_additional setting when returning secure non-recursive
4399 - do not store referral in msg cache for nonRD queries.
4400 - store verification status in the rrset cache to speed up future
4402 - mark rrsets indeterminate and insecure if they are found to be so.
4403 and store this in the cache.
4405 24 August 2007: Wouter
4406 - message is bogus if unsecure authority rrsets are present.
4407 - val-clean-additional option, so you can turn it off.
4408 - move rrset verification out of the specific proof types into one
4409 routine. This makes the proof routines prettier.
4410 - fixup cname handling in validator, cname-to-positive and cname-to-
4412 - Do not synthesize DNSKEY and DS responses from the rrset cache if
4413 the rrset is from the additional section. Signatures may have
4414 fallen off the packet, and cause validation failure.
4415 - more verbose signature date errors (with the date attached).
4416 - increased default infrastructure cache size. It is important for
4417 performance, and 1000 entries are only 212k (or a 400 k total cache
4418 size). To 10000 entries (for 2M entries, 4M cache size).
4420 23 August 2007: Wouter
4421 - CNAME handling - move needs_validation to before val_new().
4422 val_new() setups the chase-reply to be an edited copy of the msg.
4423 new classification, and find signer can find for it.
4424 removal of unsigned crap from additional, and query restart for
4426 - refuse to follow wildcarded DNAMEs when validating.
4427 But you can query for qtype ANY, or qtype DNAME and validate that.
4429 22 August 2007: Wouter
4431 - review - use val_error().
4433 21 August 2007: Wouter
4434 - ANY response validation.
4435 - store security status in cache.
4436 - check cache security status and either send the query to be
4437 validated, return the query to client, or send servfail to client.
4438 Sets AD bit on validated replies.
4439 - do not examine security status on an error reply in mesh_done.
4440 - construct DS, DNSKEY messages from rrset cache.
4441 - manual page entry for override-date.
4443 20 August 2007: Wouter
4444 - validate and positive validation, positive wildcard NSEC validation.
4445 - nodata validation, nxdomain validation.
4447 18 August 2007: Wouter
4448 - process DNSKEY response in FINDKEY state.
4450 17 August 2007: Wouter
4451 - work on DS2KE routine.
4452 - val_nsec.c for validator NSEC proofs.
4453 - unit test for NSEC bitmap reading.
4454 - dname iswild and canonical_compare with unit tests.
4456 16 August 2007: Wouter
4458 - latest release libevent 1.3c and 1.3d have threading fixed.
4459 - key entry fixup data pointer and ttl absolute.
4460 - This makes a key-prime succeed in validator, with DS or DNSKEY as
4462 - fixup canonical compare byfield routine, fix bug and also neater.
4463 - fixed iterator response type classification for queries of type
4465 dig ANY gives sometimes NS rrset in AN and NS section, and parser
4466 removes the NS section duplicate. dig NS gives sometimes the NS
4467 in the answer section, as referral.
4468 - validator FINDKEY state.
4470 15 August 2007: Wouter
4471 - crypto calls to verify signatures.
4472 - unit test for rrsig verification.
4474 14 August 2007: Wouter
4475 - default outgoing ports changed to avoid port 2049 by default.
4476 This port is widely blocked by firewalls.
4477 - count infra lameness cache in memory size.
4478 - accounting of memory improved
4479 - outbound entries are allocated in the query region they are for.
4480 - extensive debugging for memory allocations.
4481 - --enable-lock-checks can be used to enable lock checking.
4482 - protect undefs in config.h from autoheaders ministrations.
4483 - print all received udp packets. log hex will print on multiple
4485 - fixed error in parser with backwards rrsig references.
4486 - mark cycle targets for iterator did not have CD flag so failed
4489 13 August 2007: Wouter
4490 - fixup makefile, if lexer is missing give nice error and do not
4491 mess up the dependencies.
4492 - canonical compare routine updated.
4493 - canonical hinfo compare.
4494 - printout list of the queries that the mesh is working on.
4496 10 August 2007: Wouter
4497 - malloc and free overrides that track total allocation and frees.
4498 for memory debugging.
4499 - work on canonical sort.
4501 9 August 2007: Wouter
4502 - canonicalization, signature checks
4503 - dname signature label count and unit test.
4504 - added debug heap size print to memory printout.
4505 - typo fixup in worker.c
4506 - -R needed on solaris.
4507 - validator override option for date check testing.
4509 8 August 2007: Wouter
4510 - ldns _raw routines created (in ldns trunk).
4511 - sigcrypt DS digest routines
4512 - val_utils uses sigcrypt to perform signature cryptography.
4513 - sigcrypt keyset processing
4515 7 August 2007: Wouter
4516 - security status type.
4517 - security status is copied when rdata is equal for rrsets.
4518 - rrset id is updated to invalidate all the message cache entries
4519 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
4521 - val_sigcrypt file for validator signature checks.
4523 6 August 2007: Wouter
4524 - key cache for validator.
4525 - moved isroot and dellabel to own dname routines, with unit test.
4527 3 August 2007: Wouter
4529 - scrubber check section of lame NS set.
4530 - trust anchors can be in config file or read from zone file,
4531 DS and DNSKEY entries.
4532 - unit test trust anchor storage.
4533 - trust anchors converted to packed rrsets.
4534 - key entry definition.
4536 2 August 2007: Wouter
4537 - configure change for latest libevent trunk version (needs -lrt).
4538 - query_done and walk_supers are moved out of module interface.
4539 - fixup delegation point duplicates.
4540 - fixup iterator scrubber; lame NS set is let through the scrubber
4541 so that the classification is lame.
4542 - validator module exists, and does nothing but pass through,
4543 with calling of next module and return.
4546 1 August 2007: Wouter
4547 - set version to 0.5
4548 - module work for module to module interconnections.
4549 - config of modules.
4550 - detect cycle takes flags.
4552 31 July 2007: Wouter
4556 30 July 2007: Wouter
4557 - changed random state init, so that sequential process IDs are not
4558 cancelled out by sequential thread-ids in the random number seed.
4559 - the fwd_three test, which sends three queries to unbound, and
4560 unbound is kept waiting by ldns-testns for 3 seconds, failed
4561 because the retry timeout for default by unbound is 3 seconds too,
4562 it would hit that timeout and fail the test. Changed so that unbound
4563 is kept waiting for 2 seconds instead.
4565 27 July 2007: Wouter
4566 - removed useless -C debug option. It did not work.
4567 - text edit of documentation.
4568 - added doc/CREDITS file, referred to by the manpages.
4571 26 July 2007: Wouter
4572 - cycle detection, for query state dependencies. Will attempt to
4573 circumvent the cycle, but if no other targets available fails.
4574 - unit test for AXFR, IXFR response.
4575 - test for cycle detection.
4577 25 July 2007: Wouter
4578 - testbound read ADDRESS and check it.
4579 - test for version.bind and friends.
4580 - test for iterator chaining through several referrals.
4581 - test and fixup for refetch for glue. Refetch fails if glue
4582 is still not provided.
4584 24 July 2007: Wouter
4585 - Example section in config manual.
4586 - Addr stored for range and moment in replay.
4588 20 July 2007: Wouter
4589 - Check CNAME chain before returning cache entry with CNAMEs.
4590 - Option harden-glue, default is on. It will discard out of zone
4591 data. If disabled, performance is faster, but spoofing attempts
4592 become a possibility. Note that still normalize scrubbing is done,
4593 and that the potentially spoofed data is used for infrastructure
4594 and not returned to the client.
4595 - if glue times out, refetch by asking parent of delegation again.
4596 Much like asking for DS at the parent side.
4597 - TODO items from forgery-resilience draft.
4598 and on memory handling improvements.
4599 - renamed module_event_timeout to module_event_noreply.
4600 - memory reporting code; reports on memory usage after handling
4601 a network packet (not on cache replies).
4603 19 July 2007: Wouter
4604 - shuffle NS selection when getting nameserver target addresses.
4605 - fixup of deadlock warnings, yield cpu in checklock code so that
4606 freebsd scheduler selects correct process to run.
4607 - added identity and version config options and replies.
4608 - store cname messages complete answers.
4610 18 July 2007: Wouter
4611 - do not query addresses, 127.0.0.1, and ::1 by default.
4613 17 July 2007: Wouter
4614 - forward zone options in config file.
4615 - forward per zone in iterator. takes precendence over stubs.
4616 - fixup commithooks.
4617 - removed forward-to and forward-to-port features, subsumed by
4619 - fix parser to handle absent server: clause.
4620 - change untrusted rrset test to account for scrubber that is now
4621 applied during the test (which removes the poison, by the way).
4622 - feature, addresses can be specified with @portnumber, like nsd.conf.
4623 - test config files changed over to new forwarder syntax.
4625 27 June 2007: Wouter
4626 - delete of mesh does a postorder traverse of the tree.
4627 - found and fixed a memory leak. For TTL=0 messages, that would
4628 not be cached, instead the msg-replyinfo structure was leaked.
4629 - changed server selection so it will filter out hosts that are
4630 unresponsive. This is defined as a host with the maximum rto value.
4631 This means that unbound tried the host for retries up to 120 secs.
4632 The rto value will time out after host-ttl seconds from the cache.
4633 This keeps such unresolvable queries from taking up resources.
4634 - utility for keeping histogram.
4636 26 June 2007: Wouter
4637 - mesh is called by worker, and iterator uses it.
4638 This removes the hierarchical code.
4639 QueryTargets state and Finished state are merged for iterator.
4640 - forwarder mode no longer sets AA bit on first reply.
4641 - rcode in walk_supers is not needed.
4643 25 June 2007: Wouter
4645 - error encode routine for ease.
4647 22 June 2007: Wouter
4648 - removed unused _node iterator value from rbtree_t. Takes up space.
4649 - iterator can handle querytargets state without a delegation point
4650 set, so that a priming(stub) subquery error can be handled.
4651 - iterator stores if it is priming or not.
4652 - log_query_info() neater logging.
4653 - changed iterator so that it does not alter module_qstate.qinfo
4654 but keeps a chase query info. Also query_flags are not altered,
4655 the iterator uses chase_flags.
4656 - fixup crash in case no ports for the family exist.
4658 21 June 2007: Wouter
4659 - Fixup secondary buffer in case of error callback.
4660 - cleanup slumber list of runnable states.
4661 - module_subreq_depth fails to work in slumber list.
4662 - fixup query release for cached results to sub targets.
4663 - neater error for tcp connection failure, shows addr in verbose.
4664 - rbtree_init so that it can be used with preallocated memory.
4666 20 June 2007: Wouter
4667 - new -C option to enable coredumps after forking away.
4669 - fixup CNAME generation by scrubber, and memory allocation of it.
4670 - fixup deletion of serviced queries when all callbacks delete too.
4671 - set num target queries to 0 when you move them to slumber list.
4672 - typo in check caused subquery errors to be ignored, fixed.
4673 - make lint happy about rlim_t.
4674 - freeup of modules after freeup of module-states.
4675 - duplicate replies work, this uses secondary udp buffer in outnet.
4677 19 June 2007: Wouter
4678 - nicer layout in stats.c, review 0.3 change.
4679 - spelling improvement, review 0.3 change.
4680 - uncapped timeout for server selection, so that very fast or slow
4681 servers will stand out from the rest.
4682 - target-fetch-policy: "3 2 1 0 0" config setting.
4683 - fixup queries answered without RD bit (for root prime results).
4684 - refuse AXFR and IXFR requests.
4685 - fixup RD flag in error reply from iterator. fixup RA flag from
4687 - fixup encoding of very short edns buffer sizes, now sets TC bit.
4688 - config options harden-short-bufsize and harden-large-queries.
4690 18 June 2007: Wouter
4691 - same, move subqueries to slumber list when first has resolved.
4692 - fixup last fix for duplicate callbacks.
4693 - another offbyone in targetcounter. Also in Java prototype by the way.
4695 15 June 2007: Wouter
4696 - if a query asks to be notified of the same serviced query result
4697 multiple times, this will succeed. Only one callback will happen;
4698 multiple outbound-list entries result (but the double cleanup of it
4700 - when iterator moves on due to CNAME or referral, it will remove
4701 the subqueries (for other targets). These are put on the slumber
4703 - state module wait subq is OK with no new subqs, an old one may have
4704 stopped, with an error, and it is still waiting for other ones.
4705 - if a query loops, halt entire query (easy way to clean up properly).
4707 14 June 2007: Wouter
4708 - num query targets was > 0 , not >= 0 compared, so that fetch
4709 policy of 0 did nothing.
4711 13 June 2007: Wouter
4712 - debug option: configure --enable-static-exe for compile where
4713 ldns and libevent are linked statically. Default is off.
4714 - make install and make uninstall. Works with static-exe and without.
4715 installation of unbound binary and manual pages.
4716 - alignement problem fix on solaris 64.
4717 - fixup address in case of TCP error.
4719 12 June 2007: Wouter
4720 - num target queries was set to 0 at a bad time. Default it to 0 and
4721 increase as target queries are done.
4722 - synthesize CNAME and DNAME responses from the cache.
4723 - Updated doxygen config for doxygen 1.5.
4724 - aclocal newer version.
4725 - doxygen 1.5 fixes for comments (for the strict check on docs).
4727 11 June 2007: Wouter
4728 - replies on TCP queries have the address field set in replyinfo,
4729 for serviced queries, because the initiator does not know that
4730 a TCP fallback has occured.
4731 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
4732 if qtype directly queries for the type (and then only show that
4733 'unknown type' in the answer section).
4734 - fixed message parsing where rrsigs on their own would be put
4735 in the signature list over the rrsig type.
4738 - fixup error in double linked list insertion for subqueries and
4739 for outbound list of serviced queries for iterator module.
4740 - nicer printout of outgoing port selection.
4741 - fixup cname target readout.
4742 - nicer debug output.
4743 - fixup rrset counts when prepending CNAMEs to the answer.
4744 - fixup rrset TTL for prepended CNAMEs.
4745 - process better check for looping modules, and which submodule to
4747 - subreq insertion code fixup for slumber list.
4748 - VERB_DETAIL, verbosity: 2 level gives short but readable output.
4749 VERB_ALGO, verbosity: 3 gives extensive output.
4750 - fixup RA bit in cached replies.
4751 - fixup CNAME responses from the cache no longer partial response.
4752 - error in network send handled without leakage.
4753 - enable ip6 from config, and try ip6 addresses if available,
4754 if ip6 is not connected, skips to next server.
4757 - iterator state finished.
4758 - subrequests without parent store in cache and stop.
4759 - worker slumber list for ongoing promiscuous queries.
4760 - subrequest error handling.

4763 - debug routine to print dns_msg as handled by iterator.
4764 - memleak in config file stubs fixup.
4765 - more small bugs, in scrubber, query compare no ID for lookup,
4766 in dname validation for NS targets.
4767 - sets entry.key for new special allocs.
4768 - lognametypeclass can display unknown types and classes.
4771 - random selection of equally preferred nameserver targets.
4772 - reply info copy routine. Reuses existing code.
4773 - cache lameness in response handling.
4774 - do not touch qstate after worker_process_query because it may have
4775 been deleted by that routine.
4776 - Prime response state.
4777 - Process target response state.
4778 - some memcmp changed to dname_compare for case preservation.
4781 - normalize incoming messages. Like unbound-java, with CNAME chain
4782 checked, DNAME checked, CNAME's synthesized, glue checked.
4783 - sanitize incoming messages.
4784 - split msgreply encode functions into own file msgencode.c.
4785 - msg_parse to queryinfo/replyinfo conversion more versatile.
4786 - process_response, classify response, delegpt_from_message.
4789 - querytargets state.
4790 - dname_subdomain_c() routine.
4791 - server selection, based on RTT. ip6 is filtered out if not available,
4792 and lameness is checked too.
4793 - delegation point copy routine.
4796 - removed FLAG_CD from message and rrset caches. This was useful for
4797 an agnostic forwarder, but not for a sophisticated (trust value per
4798 rrset enabled) cache.
4799 - iterator reponse typing.
4800 - iterator cname handle.
4801 - iterator prime start.
4803 - processInitRequest and processInitRequest2.
4804 - cache synthesizes referral messages, with DS and NSEC.
4805 - processInitRequest3.
4806 - if a request creates multiple subrequests these are all activated.
4809 - routines to lock and unlock array of rrsets moved to cache/rrset.
4810 - lookup message from msg cache (and copy to region).
4811 - fixed cast error in dns msg lookup.
4812 - message with duplicate rrset does not increase its TTLs twice.
4813 - 'qnamesize' changed to 'qname_len' for similar naming scheme.
4816 - Acknowledge use of unbound-java code in iterator. Nicer readme.
4817 - services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
4818 rrset cache from module environment.
4819 - packed rrset key has type and class as easily accessable struct
4820 members. They are still kept in network format for fast msg encode.
4821 - dns cache find_delegation routine.
4822 - iterator main functions setup.
4823 - dns cache lookup setup.
4826 - small changes to prepare for subqueries.
4827 - iterator forwarder feature separated out.
4828 - iterator hints stub code, config file stub code, so that first
4829 testing can proceed locally.
4830 - replay tests now have config option to enable forwarding mode.
4833 - outside network does precise timers for roundtrip estimates for rtt
4834 and for setting timeout for UDP. Pending_udp takes milliseconds.
4835 - cleaner iterator sockaddr conversion of forwarder address.
4836 - iterator/iter_utils and iter_delegpt setup.
4840 - outbound query list for modules and support to callback with the
4841 outbound entry to the module.
4842 - testbound support for new serviced queries.
4843 - test for retry to TCP cannot use testbound any longer.
4844 - testns test for EDNS fallback, test for TCP fallback already exists.
4845 - fixes for no-locking compile.
4846 - mini_event timer precision and fix for change in timeouts during
4847 timeout callback. Fix for fwd_three tests, performed nonexit query.
4850 - small comment on hash table locking.
4851 - outside network serviced queries, contain edns and tcp fallback,
4852 and udp retries and rtt timing.

4861 - daemon code slightly cleaner, only creates caches once.
4865 - unit test for host cache.
4868 - Port to OS/X and Dec Alpha. Printf format and alignment fixes.
4869 - extensive lock debug report on join timeout.
4870 - proper RTT calculation, in utility code.
4871 - setup of services/cache/infra, host cache.

4875 - fixup to pass reply_info in testcode and in netevent.
4878 - created release-0.3 svn tag.
4880 - fixed compression - no longer compresses root name.
4883 - outside network cleans up waiting tcp queries on exit.
4885 - testbound replay with retry in TCP mode.
4886 - tpkg test for retry in TCP mode, against ldns-testns server.
4887 - daemon checks max number of open files and complains if not enough.
4888 - test where data expires in the cache.
4889 - compiletests: fixed empty body ifstatements in alloc.c, in case
4893 - outgoing network keeps list of available tcp buffers for outgoing
4895 - outgoing-num-tcp config option.
4896 - outgoing network keeps waiting list of queries waiting for buffer.
4897 - netevent supports outgoing tcp commpoints, nonblocking connects.
4900 - EDNS read from query, used to make reply smaller.
4901 - advertised edns value constants.
4902 - EDNS BADVERS response, if asked for too high edns version.
4903 - EDNS extended error reponses once the EDNS record from the query
4904 has successfully been parsed.
4907 - msgreply sizefunc is more accurate.
4908 - config settings for rrset cache size and slabs.
4909 - hashtable insert takes argument so that a thread can use its own
4910 alloc cache to store released keys.
4911 - alloc cache special_release() locks if necessary.
4912 - rrset trustworthiness type added.
4913 - thread keeps a scratchpad region for handling messages.
4914 - writev used in netevent to write tcp length and data after another.
4915 This saves a roundtrip on tcp replies.
4916 - test for one rrset updated in the cache.
4917 - test for one rrset which is not updated, as it is not deemed

5052 Note that no TTLs are managed.
5054 29 March 2007: Wouter
5055 - writev or sendmsg used when answering from cache.
5056 This avoids a copy of the data.
5057 - do not do useless byteswap on query id. Store reply flags in uint16
5058 for easier access (and no repeated byteswapping).

5090 - lock-verify can handle references to locks that are created
5091 in files it has not yet read in.
5092 - threaded hash table test.
5093 - unit test runs lock-verify afterwards and checks result.
5094 - need writelock to update data on hash_insert.
5095 - message cache code, msgreply code.
5097 21 March 2007: Wouter

5137 6 March 2007: Wouter
5138 - Testbed works with threading (different machines, different options).
5139 - alloc work, does the special type.
5141 2 March 2007: Wouter

5160 - During reloads the daemon will temporarily handle signals,
5161 so that they do not result in problems.
5162 - Also randomize the outgoing port range for tests.
5163 - If query list is full, will stop selecting listening ports for read.
5164 This makes all threads service incoming requests, instead of one.
5165 No memory is leaking during reloads, service of queries, etc.
5166 - test that uses ldns-testns -f to test threading. Have to answer
5167 three queries at the same time.
5168 - with verbose=0 operates quietly.

5178 23 February 2007: Wouter
5179 - Can do reloads on sigHUP. Everything is stopped, and freed,
5180 except the listening ports. Then the config file is reread.
5181 And everything is started again (and listening ports if needed).
5182 - Ports for queries are shared.
5183 - config file added interface:, chroot: and username:.
5184 - config file: directory, logfile, pidfile. And they work too.

5212 - makefile supports LIBOBJ replacements.
5213 - docs checks ignore compat code.
5214 - added util/mini-event.c and .h, a select based alternative used with
5215 ./configure --with-libevent=no
5216 It is limited to 1024 file descriptors, and has less features.
5217 - will not create ip6 sockets if ip6 not on the machine.
5219 15 February 2007: Wouter
5220 - port to FreeBSD 4.11 Dec Alpha. Also works on Solaris 10 sparc64,

5223 - fixed rbtree cleanup with postorder traverse.
5224 - fixed pending messages are deleted when handled.
