251	- Code cleanup patch from Dag-Erling Smorgrav, with compiler issue
252	  fixes from FreeBSD's copy of Unbound, he notes:
253	  Generate unbound-control-setup.sh at build time so it respects
254	  prefix and sysconfdir from the configure script.  Also fix the
255	  umask to match the comment, and the comment to match the umask.
256	  Add const and static where needed.  Use unions instead of
257	  playing pointer poker.  Move declarations that are needed in
258	  multiple source files into a shared header.  Move sldns_bgetc()
259	  from parse.c to buffer.c where it belongs.  Introduce a new
260	  header file, worker.h, which declares the callbacks that
261	  all workers must define.  Remove those declarations from
262	  libworker.h.	Include the correct headers in the correct places.
263	  Fix a few dummy callbacks that don't match their prototype.
264	  Fix some casts.  Hide the sbrk madness behind #ifdef HAVE_SBRK.
265	  Remove a useless printf which breaks reproducible builds.
266	  Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
267	  no longer used.  Add unbound-control-setup.sh to the list of
268	  generated files.  The prototype for libworker_event_done_cb()
269	  needs to be moved from libunbound/libworker.h to
270	  libunbound/worker.h.
271	- Fixup out-of-directory compile with unbound-control-setup.sh.in.
272	- make depend.

296	- Added unbound-control-setup.cmd from Yuri Voinov to the windows
297	  unbound distribution set.  It requires openssl installed in %PATH%.

307	- iana portlist updated.
308	- Add unbound-control flush_negative that flushed nxdomains, nodata,

311	  negatively cached from the previous network.
312
31323 April 2014: Wouter
314	- Patch from Jeremie Courreges-Anglas to use arc4random_uniform

319
32011 April 2014: Wouter

333	  +i annotation in output of list_forwards, also for list_stubs
334	  (for NetworkManager integration.)
335	- Fix #554: use unsigned long to print 64bit statistics counters on
336	  64bit systems.
337	- Fix #558: failed prefetch lookup does not remove cached response
338	  but delays next prefetch (in lieu of caching a SERVFAIL).
339	- Fix #545: improved logging, the ip address of the error is printed
340	  on the same log-line as the error.

375
37620 February 2014: Matthijs
377	- Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
378	  received. This is okay according 4035, but not after revising
379	  existence in 4592.  NSEC empty non-terminals exist and thus the
380	  RCODE should have been NOERROR. If this occurs, and the RRsets
381	  are secure, we set the RCODE to NOERROR and the security status
382	  of the reponse is also considered secure.
383
38414 February 2014: Wouter
385	- Works on Minix (3.2.1).

418	  parse sldns.
419
42030 January 2014: Wouter
421	- delay-close does not act if there are udp-wait queries, so that
422	  it does not make a socketdrain DoS easier.
423

425	- iana portlist updated.
426	- iana portlist test updated so it does not touch the source

428	- delay-close: msec option that delays closing ports for which
429	  the UDP reply has timed out.  Keeps the port open, only accepts
430	  the correct reply.  This correct reply is not used, but the port
431	  is open so that no port-denied ICMPs are generated.
432
43327 January 2014: Wouter
434	- reuseport is attempted, then fallback to without on failure.
435
43624 January 2014: Wouter

492	- Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
493	  more specific interface port 53 can be used at the same time, and
494	  one of the daemons is unbound.
495	- iana portlist update.
496	- separate ldns into core ldns inside ldns/ subdirectory.  No more
497	  --with-ldns is needed and unbound does not rely on libldns.
498	- portability fixes for new USE_SLDNS ldns subdir codebase.
499
50022 Oct 2013: Wouter
501	- Patch from Neel Goyal: Add an API call to set an event base on an
502	  existing ub_ctx.  This basically just destroys the current worker and
503	  sets the event base to the current.  And fix a deadlock in
504	  ub_resolve_event – the cfglock is held when libworker_create is
505	  called.  This ends up trying to acquire the lock again in
506	  context_obtain_alloc in the call chain.
507	- Fix #528: if very high logging (4 or more) segfault on allow_snoop.
508
50926 Sep 2013: Wouter
510	- unbound-event.h is installed if configured --with-libevent.  It
511	  contains low-level library calls, that use libevent's event_base
512	  and an ldns_buffer for the wire return packet to perform async
513	  resolution in the client's eventloop.

1001
10029 March 2012: Wouter
1003	- Applied line-buffer patch from Augie Schwer to validation.reporter.sh.
1004
10052 March 2012: Wouter
1006	- flush_infra cleans timeouted servers from the cache too.
1007	- removed warning from --enable-ecdsa.
1008
10091 March 2012: Wouter
1010	- forward-first option.  Tries without forward if a query fails.
1011	  Also stub-first option that is similar.
1012
101328 February 2012: Wouter
1014	- Fix from code review, if EINPROGRESS not defined chain if statement
1015	  differently.
1016
101727 February 2012: Wouter
1018	- Fix bug#434: on windows check registry for config file location
1019	  for unbound-control.exe, and unbound-checkconf.exe.
1020
102123 February 2012: Wouter
1022	- Fix to squelch 'network unreachable' errors from tcp connect in
1023	  logs, high verbosity will show them.
1024
102516 February 2012: Wouter
1026	- iter_hints is now thread-owned in module env, and thus threadsafe.
1027	- Fix prefetch and sticky NS, now the prefetch works.  It picks
1028	  nameservers that 'would be valid in the future', and if this makes
1029	  the NS timeout, it updates that NS by asking delegation from the
1030	  parent again.  If child NS has longer TTL, that TTL does not get
1031	  refreshed from the lookup to the child nameserver.
1032
103315 February 2012: Wouter
1034	- Fix forward-zone memory, uses malloc and frees original root dp.
1035	- iter hints (stubs) uses malloc inside for more dynamicity.
1036	- unbound-control forward_add, forward_remove, stub_add, stub_remove
1037	  can modify stubs and forwards for running unbound (on mobile computer)
1038	  they can also add and remove domain-insecure for the zone.
1039
104014 February 2012: Wouter
1041	- Fix sticky NS (ghost domain problem) if prefetch is yes.
1042	- iter forwards uses malloc inside for more dynamicity.
1043
104413 February 2012: Wouter
1045	- RT#2955. Fix for cygwin compilation.
1046	- iana portlist updated.
1047
104810 February 2012: Wouter
1049	- Slightly smaller critical region in one case in infra cache.
1050	- Fix timeouts to keep track of query type, A, AAAA and other, if
1051	  another has caused timeout blacklist, different type can still probe.
1052	- unit test fix for nomem_cnametopos.rpl race condition.
1053
10549 February 2012: Wouter
1055	- Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
1056
10578 February 2012: Wouter
1058	- implement draft-ietf-dnsext-ecdsa-04; which is in IETF LC; This
1059	  implementation is experimental at this time and not recommended
1060	  for use on the public internet (the protocol numbers have not
1061	  been assigned).  Needs recent ldns with --enable-ecdsa.
1062	- fix memory leak in errorcase for DSA signatures.
1063	- iana portlist updated.
1064	- workaround for openssl 0.9.8 ecdsa sha2 and evp problem.
1065
10663 February 2012: Wouter
1067	- fix for windows, rename() is not posix compliant on windows.
1068
10692 February 2012: Wouter
1070	- 1.4.16 release tag.
1071	- svn trunk is 1.4.17 in development.
1072	- iana portlist updated.
1073
10741 February 2012: Wouter
1075	- Fix validation failures (like: validation failure xx: no NSEC3
1076	  closest encloser from yy for DS zz. while building chain of trust,
1077	  because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
1078	  for an NSEC3.  Now it does not change rdata, and fixes TTL.
1079
108030 January 2012: Wouter
1081	- Fix version-number in libtool to be version-info so it produces
1082	  libunbound.so.2 like it should.
1083
108426 January 2012: Wouter
1085	- Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.
1086	- trunk 1.4.16; includes changes memset testcode, #424 openindiana,
1087	  and keyfile write fixup.
1088	- applied patch to support outgoing-interface with ub_ctx_set_option.
1089
109023 January 2012: Wouter
1091	- Fix memset in test code.
1092
109320 January 2012: Wouter
1094	- Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
1095
109619 January 2012: Wouter
1097	- Fix to write key files completely to a temporary file, and if that
1098	  succeeds, replace the real key file.  So failures leave a useful file.
1099
110018 January 2012: Wouter
1101	- tag 1.4.15rc1 created
1102	- updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
1103
110417 January 2012: Wouter
1105	- Fix bug where canonical_compare of RRSIG did not downcase the
1106	  signer-name.  This is mostly harmless because RRSIGs do not have
1107	  to be sorted in canonical order, usually.
1108
110912 January 2012: Wouter
1110	- bug#428: add ub_version() call to libunbound.  API version increase,
1111	  with (binary) backwards compatibility for the previous version.
1112
111310 January 2012: Wouter
1114	- Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
1115	  that would be permissible by the RFCs but it is not the TTL in the
1116	  cache.
1117	- iana portlist updated.
1118	- uninitialised variable in reprobe for rtt blocked domains fixed.
1119	- lintfix and new flex output.
1120
11212 January 2012: Wouter
1122	- Fix to randomize hash function, based on 28c3 congress, reported
1123	  by Peter van Dijk.
1124
112524 December 2011: Wouter
1126	- Fix for memory leak (about 20 bytes when a tcp or udp send operation
1127	  towards authority servers failed, takes about 50.000 such failures to
1128	  leak one Mb, such failures are also usually logged), reported by
1129	  Robert Fleischmann.
1130	- iana portlist updated.
1131
113219 December 2011: Wouter
1133	- Fix for VU#209659 CVE-2011-4528: Unbound denial of service
1134	  vulnerabilities from nonstandard redirection and denial of existence
1135	  http://www.unbound.net/downloads/CVE-2011-4528.txt
1136	- robust checks for next-closer NSEC3s.
1137	- tag 1.4.14 created.
1138	- trunk has 1.4.15 in development.
1139
114015 December 2011: Wouter
1141	- remove uninit warning from cachedump code.
1142	- Fix parse error on negative SOA RRSIGs if badly ordered in the packet.
1143
114413 December 2011: Wouter
1145	- iana portlist updated.
1146	- svn tag 1.4.14rc1
1147	- fix infra cache comparison.
1148	- Fix to constrain signer_name to be a parent of the lookupname.
1149
11505 December 2011: Wouter
1151	- Fix getaddrinfowithincludes on windows with fedora16 mingw32-gcc.

1157	- configure generated with autoconf 2.68.
1158
115930 November 2011: Wouter
1160	- Fix for tcp-upstream and ssl-upstream for if a laptop sleeps, causes
1161	  SERVFAILs.  Also fixed for UDP (but less likely).
1162
116328 November 2011: Wouter
1164	- Fix quartile time estimate, it was too low, (thanks Jan Komissar).
1165	- iana ports updated.
1166

1169	- iana ports updated.
1170
117110 November 2011: Wouter
1172	- Makefile changed for BSD make compatibility.
1173
11749 November 2011: Wouter
1175	- added unit test for SSL service and SSL-upstream.
1176
11778 November 2011: Wouter
1178	- can configure ssl service to one port number, and not on others.
1179	- fixup windows compile with ssl support.
1180	- Fix double free in unbound-host, reported by Steve Grubb.
1181	- iana portlist updated.
1182
11831 November 2011: Wouter
1184	- dns over ssl support as a client, ssl-upstream yes turns it on.
1185	  It performs an SSL transaction for every DNS query (250 msec).
1186	- documentation for new options: ssl-upstream, ssl-service-key and
1187	  ssl-service.pem.
1188	- iana portlist updated.
1189	- fix -flto detection on Lion for llvm-gcc.
1190
119131 October 2011: Wouter
1192	- dns over ssl support, ssl-service-pem and ssl-service-key files
1193	  can be given and then TCP queries are serviced wrapped in SSL.
1194
119527 October 2011: Wouter
1196	- lame-ttl and lame-size options no longer exist, it is integrated
1197	  with the host info.  They are ignored (with verbose warning) if
1198	  encountered to keep the config file backwards compatible.
1199	- fix iana-update for changing gzip compression of results.
1200	- fix export-all-symbols on OSX.
1201
120226 October 2011: Wouter

1207
120824 October 2011: Wouter
1209	- Fix resolve of partners.extranet.microsoft.com with a fix for the
1210	  server selection for choosing out of a (particular) list of bad
1211	  choices. (bug#415)
1212	- Fix make_new_space function so that the incoming query is not
1213	  overwritten if a jostled out query causes a waiting query to be
1214	  resumed that then fails and sends an error message.  (Thanks to
1215	  Matthew Lee).
1216
121721 October 2011: Wouter
1218	- fix --enable-allsymbols, fptr wlist is disabled on windows with this
1219	  option enabled because of memory layout exe vs dll.
1220
122119 October 2011: Wouter
1222	- fix unbound-anchor for broken strptime on OSX lion, detected
1223	  in configure.
1224	- Detect if GOST really works, openssl1.0 on OSX fails.
1225	- Implement ipv6%interface notation for scope_id usage.
1226
122717 October 2011: Wouter
1228	- better documentation for inform_super (Thanks Yang Zhe).
1229
123014 October 2011: Wouter
1231	- Fix for out-of-memory condition in libunbound (thanks
1232	  Robert Fleischman).
1233
123413 October 2011: Wouter
1235	- Fix --enable-allsymbols, it depended on link specifics of the
1236	  target platform, or fptr_wlist assertion failures could occur.
1237
123812 October 2011: Wouter
1239	- updated contrib/unbound_munin_ to family=auto so that it works with
1240	  munin-node-configure automatically (if installed as
1241	  /usr/local/share/munin/plugins/unbound_munin_ ).
1242
124327 September 2011: Wouter
1244	- unbound.exe -w windows option for start and stop service.
1245
124623 September 2011: Wouter
1247	- TCP-upstream calculates tcp-ping so server selection works if there
1248	  are alternatives.
1249
125020 September 2011: Wouter
1251	- Fix classification of NS set in answer section, where there is a
1252	  parent-child server, and the answer has the AA flag for dir.slb.com.
1253	  Thanks to Amanda Constant from Secure64.
1254
125516 September 2011: Wouter
1256	- fix bug #408: accept patch from Steve Snyder that comments out
1257	  unused functions in lookup3.c.
1258	- iana portlist updated.
1259	- fix EDNS1480 change memleak and TCP fallback.
1260	- fix various compiler warnings (reported by Paul Wouters).
1261	- max sent count.  EDNS1480 only for rtt < 5000.  No promiscuous
1262	  fetch if sentcount > 3, stop query if sentcount > 16.  Count is
1263	  reset when referral or CNAME happens.  This makes unbound better
1264	  at managing large NS sets, they are explored when there is continued
1265	  interest (in the form of queries).
1266
126715 September 2011: Wouter
1268	- release 1.4.13.
1269	- trunk contains 1.4.14 in development.
1270	- Unbound probes at EDNS1480 if there an EDNS0 timeout.
1271
127212 September 2011: Wouter
1273	- Reverted dns EDNS backoff fix, it did not help and needs
1274	  fragmentation fixes instead.
1275	- tag 1.4.13rc2
1276
12777 September 2011: Wouter
1278	- Fix operation in ipv6 only (do-ip4: no) mode.
1279
12806 September 2011: Wouter
1281	- fedora specfile updated.
1282
12835 September 2011: Wouter
1284	- tag 1.4.13rc1
1285
12862 September 2011: Wouter
1287	- iana portlist updated.
1288
128926 August 2011: Wouter
1290	- Fix num-threads 0 does not segfault, reported by Simon Deziel.
1291	- Fix validation failures due to EDNS backoff retries, the retry
1292	  for fetch of data has want_dnssec because the iter_indicate_dnssec
1293	  function returns true when validation failure retry happens, and
1294	  then the serviced query code does not fallback to noEDNS, even if
1295	  the cache says it has this.  This helps for DLV deployment when
1296	  the DNSSEC status is not known for sure before the lookup concludes.
1297
129824 August 2011: Wouter
1299	- Applied patch from Karel Slany that fixes a memory leak in the
1300	  unbound python module, in string conversions.
1301
130222 August 2011: Wouter
1303	- Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
1304	  Zhang and Luo Ce).  Unbound responds with the RR types that are
1305	  available at the name for qtype ANY and validates those RR types.
1306	  It does not test for completeness (i.e. with NSEC or NSEC3 query),
1307	  and it does not follow the CNAME or DNAME to another name (with
1308	  even more data for the already large response).
1309	- Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
1310	- Documented the options that work with control set_option command.
1311	- tcp-upstream yes/no option (works with set_option) for tunnels.
1312
131318 August 2011: Wouter
1314	- fix autoconf call in makedist crosscompile to RC or snapshot.
1315
131617 August 2011: Wouter
1317	- Fix validation of . DS query.
1318	- new xml format at IANA, new awk for iana_update.
1319	- iana portlist updated.
1320
132110 August 2011: Wouter
1322	- Fix python site-packages path to /usr/lib64.
1323	- updated patch from Tom.
1324	- fix memory and fd leak after out-of-memory condition.
1325
13269 August 2011: Wouter
1327	- patch from Tom Hendrikx fixes load of python modules.
1328
13298 August 2011: Wouter
1330	- make clean had ldns-src reference, removed.
1331
13321 August 2011: Wouter
1333	- Fix autoconf 2.68 warnings
1334
133514 July 2011: Wouter
1336	- Unbound implements RFC6303 (since version 1.4.7).
1337	- tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
1338	  meantime, those are for 1.4.13).
1339	- iana portlist updated.
1340
134113 July 2011: Wouter
1342	- Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
1343
134411 July 2011: Wouter
1345	- Fix wildcard expansion no-data reply under an optout NSEC3 zone is
1346	  validated as insecure, reported by Jia Li (lijia@cnnic.cn).
1347
13484 July 2011: Wouter
1349	- 1.4.12rc1 tag created.
1350
13511 July 2011: Wouter
1352	- version number in example config file.
1353	- fix that --enable-static-exe does not complain about it unknown.
1354
135530 June 2011: Wouter
1356	- tag relase 1.4.11, trunk is 1.4.12 development.
1357	- iana portlist updated.
1358	- fix bug#395: id bits of other query may leak out under conditions
1359	- fix replyaddr count wrong after jostled queries, which leads to
1360	  eventual starvation where the daemon has no replyaddrs left to use.
1361	- fix comment about rndc port, that referred to the old port number.
1362	- fix that the listening socket is not closed when too many remote
1363	  control connections are made at the same time.
1364	- removed ldns-src tarball inside the unbound tarball.
1365
136623 June 2011: Wouter
1367	- Changed -flto check to support clang compiler.
1368	- tag 1.4.11rc3 created.
1369
137017 June 2011: Wouter
1371	- tag 1.4.11rc1 created.
1372	- remove warning about signed/unsigned from flex (other flex version).
1373	- updated aclocal.m4 and libtool to match.
1374	- tag 1.4.11rc2 created.
1375
137616 June 2011: Wouter
1377	- log-queries: yesno option, default is no, prints querylog.
1378	- version is 1.4.11.
1379
138014 June 2011: Wouter
1381	- Use -flto compiler flag for link time optimization, if supported.
1382	- iana portlist updated.
1383
138412 June 2011: Wouter
1385	- IPv6 service address for d.root-servers.net (2001:500:2D::D).
1386
138710 June 2011: Wouter
1388	- unbound-control has version number in the header,
1389	  UBCT[version]_space_ is the header sent by the client now.
1390	- Unbound control port number is registered with IANA:
1391	  ub-dns-control  8953/tcp    unbound dns nameserver control
1392	  This is the new default for the control-port config setting.
1393	- statistics-interval prints the number of jostled queries to log.
1394
139530 May 2011: Wouter
1396	- Fix Makefile for U in environment, since wrong U is more common than
1397	  deansification necessity.
1398	- iana portlist updated.
1399	- updated ldns tarball to 1.6.10rc2 snapshot of today.
1400
140125 May 2011: Wouter
1402	- Fix assertion failure when unbound generates an empty error reply
1403	  in response to a query, CVE-2011-1922 VU#531342.
1404	- This fix is in tag 1.4.10.
1405	- defense in depth against the above bug, an error is printed to log
1406	  instead of an assertion failure.
1407
140810 May 2011: Wouter
1409	- bug#386: --enable-allsymbols option links all binaries to libunbound
1410	  and reduces install size significantly.
1411	- feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
1412	- iana portlist updated.
1413	- Fix TTL of SOA so negative TTL is separately cached from normal TTL.
1414
141514 April 2011: Wouter
1416	- configure created with newer autoconf 2.66.
1417
141812 April 2011: Wouter
1419	- bug#378: Fix that configure checks for ldns_get_random presence.
1420
14218 April 2011: Wouter
1422	- iana portlist updated.
1423	- queries with CD flag set cause DNSSEC validation, but the answer is
1424	  not withheld if it is bogus.  Thus, unbound will retry if it is bad
1425	  and curb the TTL if it is bad, thus protecting the cache for use by
1426	  downstream validators.
1427	- val-override-date: -1 ignores dates entirely, for NTP usage.
1428
142929 March 2011: Wouter
1430	- harden-below-nxdomain: changed so that it activates when the
1431	  cached nxdomain is dnssec secure.  This avoids backwards
1432	  incompatibility because those old servers do not have dnssec.
1433
143424 March 2011: Wouter
1435	- iana portlist updated.
1436	- release 1.4.9.
1437	- trunk is 1.5.0
1438
143917 March 2011: Wouter
1440	- bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
1441	  Applied but did not do the --disable-gost.
1442
144310 March 2011: Wouter
1444	- tag 1.4.9 release candidate 1 created.
1445
14463 March 2011: Wouter
1447	- updated ldns to today.
1448
14491 March 2011: Wouter
1450	- Fix no ADflag for NXDOMAIN in NSEC3 optout. And wildcard in optout.
1451	- give config parse error for multiple names on a stub or forward zone.

1463
146415 February 2011: Wouter
1465	- Added explicit note on unbound-anchor usage:
1466	  Please note usage of unbound-anchor root anchor is at your own risk
1467	  and under the terms of our LICENSE (see that file in the source).
1468
146911 February 2011: Wouter
1470	- iana portlist updated.
1471	- tpkg updated with common.sh for common functionality.
1472
14737 February 2011: Wouter
1474	- Added regression test for addition of a .net DS to the root, and
1475	  cache effects with different TTL for glue and DNSKEY.
1476	- iana portlist updated.
1477
147828 January 2011: Wouter
1479	- Fix remove private address does not throw away entire response.

1493	- iana portlist updated.
1494
149514 January 2011: Wouter
1496	- Fix so a changed NS RRset does not get moved name stuck on old
1497	  server, for type NS the TTL is not increased.
1498
149913 January 2011: Wouter
1500	- Fix prefetch so it does not get stuck on old server for moved names.
1501
150212 January 2011: Wouter
1503	- iana portlist updated.
1504

1517	- Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
1518
151921 December 2010: Wouter
1520	- algorithm compromise protection using the algorithms signalled in
1521	  the DS record.  Also, trust anchors, DLV, and RFC5011 receive this,
1522	  and thus, if you have multiple algorithms in your trust-anchor-file
1523	  then it will now behave different than before.  Also, 5011 rollover
1524	  for algorithms needs to be double-signature until the old algorithm
1525	  is revoked.
1526	  It is not an option, because I see no use to turn the security off.
1527	- iana portlist updated.
1528
152917 December 2010: Wouter
1530	- squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
1531	- fix validation in this case: CNAME to nodata for co-hosted opt-in
1532	  NSEC3 insecure delegation, was bogus, fixed to be insecure.
1533
153416 December 2010: Wouter
1535	- Fix our 'BDS' license (typo reported by Xavier Belanger).
1536
153710 December 2010: Wouter

1539	- review changes for unbound-anchor.
1540
15412 December 2010: Wouter
1542	- feature typetransparent localzone, does not block other RR types.
1543

1546
154730 November 2010: Wouter
1548	- Fix storage of EDNS failures in the infra cache.
1549	- iana portlist updated.
1550
155118 November 2010: Wouter
1552	- harden-below-nxdomain option, default off (because very old
1553	  software may be incompatible).  We could enable it by default in
1554	  the future.
1555
155617 November 2010: Wouter
1557	- implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
1558	- make test output nicer.
1559
156015 November 2010: Wouter
1561	- silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
1562	- iana portlist updated.
1563	- so-sndbuf option for very busy servers, a bit like so-rcvbuf.
1564
15659 November 2010: Wouter
1566	- unbound-anchor compiles with openssl 0.9.7.
1567
15688 November 2010: Wouter
1569	- release tag 1.4.7.
1570	- trunk is version 1.4.8.
1571	- Be lenient and accept imgw.pl malformed packet (like BIND).
1572
15735 November 2010: Wouter
1574	- do not synthesize a CNAME message from cache for qtype DS.
1575
15764 November 2010: Wouter
1577	- Use central entropy to seed threads.
1578
15793 November 2010: Wouter

1590	- Fix uninit value in dump_infra print.
1591	- Fix validation failure for parent and child on same server with an
1592	  insecure childzone and a CNAME from parent to child.
1593	- Configure detects libev-4.00.
1594
159526 October 2010: Wouter
1596	- dump_infra and flush_infra commands for unbound-control.
1597	- no timeout backoff if meanwhile a query succeeded.
1598	- Change of timeout code.  No more lost and backoff in blockage.
1599	  At 12sec timeout (and at least 2x lost before) one probe per IP
1600	  is allowed only.  At 120sec, the IP is blocked.  After 15min, a
1601	  120sec entry has a single retry packet.
1602
160325 October 2010: Wouter
1604	- Configure errors if ldns is not found.
1605
160622 October 2010: Wouter
1607	- Windows 7 fix for the installer.
1608
160921 October 2010: Wouter
1610	- Fix bug where fallback_tcp causes wrong roundtrip and edns
1611	  observation to be noted in cache.  Fix bug where EDNSprobe halted
1612	  exponential backoff if EDNS status unknown.
1613	- new unresponsive host method, exponentially increasing block backoff.
1614	- iana portlist updated.
1615
161620 October 2010: Wouter
1617	- interface automatic works for some people with ip6 disabled.
1618	  Therefore the error check is removed, so they can use the option.
1619
162019 October 2010: Wouter
1621	- Fix for request list growth, if a server has long timeout but the
1622	  lost counter is low, then its effective rtt is the one without
1623	  exponential backoff applied.  Because the backoff is not working.
1624	  The lost counter can then increase and the server is blacklisted,
1625	  or the lost counter does not increase and the server is working
1626	  for some queries.
1627
162818 October 2010: Wouter
1629	- iana portlist updated.
1630
163113 October 2010: Wouter
1632	- Fix TCP so it uses a random outgoing-interface.
1633	- unbound-anchor handles ADDPEND keystate.
1634
163511 October 2010: Wouter
1636	- Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
1637	  the zone has a secure delegation hosted on the same server did not
1638	  verify as secure (it was insecure by mistake).
1639	- iana portlist updated.
1640	- ldns tarball updated (for reading cachedumps with bad RR data).
1641
16421 October 2010: Wouter

1645
164628 September 2010: Wouter
1647	- unbound-anchor working, it creates or updates a root.key file.
1648	  Use it before you start the validator (e.g. at system boot time).

1651	- iana portlist updated.
1652
165324 September 2010: Wouter

1655
165623 September 2010: Wouter
1657	- unbound-anchor app, unbound requires libexpat (xml parser library).
1658
165922 September 2010: Wouter

1666	- iana portlist updated.
1667
166816 September 2010: Wouter
1669	- Algorithm rollover operational reality intrudes, for trust-anchor,
1670	  5011-store, and DLV-anchor if one key matches it's good enough.
1671	- iana portlist updated.
1672	- Fix reported validation error in out of memory condition.
1673
167415 September 2010: Wouter
1675	- Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
1676
167714 September 2010: Wouter
1678	- increased mesh-max-activation from 1000 to 3000 for crazy domains
1679	  like _tcp.slb.com with 262 servers.
1680	- iana portlist updated.
1681
168213 September 2010: Wouter
1683	- bug#327: Fix for cannot access stub zones until the root is primed.
1684
16859 September 2010: Wouter
1686	- unresponsive servers are not completely blacklisted (because of
1687	  firewalls), but also not probed all the time (because of the request
1688	  list size it generates).  The probe rate is 1%.
1689	- iana portlist updated.
1690
169120 August 2010: Wouter
1692	- openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
1693	  iterator get_mem includes priv_get_mem.  delegpt nodup removed.

1707	  if use sun-cc, but some systems need different flags.
1708
170916 August 2010: Wouter
1710	- Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
1711	  changes, uses m4_bpatsubst now.
1712	- make test (or make check) should be more portable and run the unit
1713	  test and testbound scripts. (make longtest has special requirements).
1714
171513 August 2010: Wouter
1716	- More pleasant remote control command parsing.
1717	- documentation added for return values reported by doxygen 1.7.1.
1718	- iana portlist updated.
1719

1732	- release tag 1.4.6.
1733	- trunk becomes 1.4.7 develop.
1734	- iana portlist updated.
1735
173622 July 2010: Wouter
1737	- more error details on failed remote control connection.
1738
173915 July 2010: Wouter
1740	- rlimit adjustments for select and ulimit can happen at the same time.
1741
174214 July 2010: Wouter
1743	- Donation text added to README.
1744	- Fix integer underflow in prefetch ttl creation from cache.  This
1745	  fixes a potential negative prefetch ttl.
1746
174712 July 2010: Wouter
1748	- Changed the defaults for num-queries-per-thread/outgoing-range.
1749	  For builtin-select: 512/960, for libevent 1024/4096 and for
1750	  windows 24/48 (because of win api).  This makes the ratio this way
1751	  to improve resilience under heavy load.  For high performance, use
1752	  libevent and possibly higher numbers.
1753
175410 July 2010: Wouter
1755	- GOST enabled if SSL is recent and ldns has GOST enabled too.
1756	- ldns tarball updated.
1757
17589 July 2010: Wouter
1759	- iana portlist updated.
1760	- Fix validation of qtype DNSKEY when a key-cache entry exists but
1761	  no rr-cache entry is used (it expired or prefetch), it then goes
1762	  back up to the DS or trust-anchor to validate the DNSKEY.
1763
17647 July 2010: Wouter
1765	- Neat function prototypes, unshadowed local declarations.
1766
17676 July 2010: Wouter
1768	- failure to chown the pidfile is not fatal any more.
1769	- testbound uses UTC timezone.
1770	- ldns tarball updated (ports and works on Minix 3.1.7).  On Minix, add
1771	  /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
1772
17735 July 2010: Wouter
1774	- log if a server is skipped because it is on the donotquery list,
1775	  at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
1776	- added feature to print configure date, target and options with -h.
1777	- added feature to print event backend system details with -h.
1778	- wdiff is not actually required by make test, updated requirements.
1779
17801 July 2010: Wouter
1781	- Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
1782	  must be signed with all algorithms from the DS rrset at the parent.
1783	  This is now checked and becomes bogus if not.
1784
178528 June 2010: Wouter
1786	- Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
1787	  in overload situations to be about 5 qps for the class of shortly
1788	  serviced queries.
1789	  The capacity of the resolver is then about (numqueriesperthread / 2)
1790	  / (average time for such long queries) qps for long queries.
1791	  And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
1792	  qps for short queries, per thread.
1793	- Fix the max number of reply-address count to be applied for duplicate
1794	  queries, and not for new query list entries.  This raises the memory
1795	  usage to a max of (16+1)*numqueriesperthread reply addresses.
1796
179725 June 2010: Wouter
1798	- Fix handling of corner case reply from lame server, follows rfc2308.
1799	  It could lead to a nodata reply getting into the cache if the search
1800	  for a non-lame server turned up other misconfigured servers.
1801	- unbound.h has extern "C" statement for easier include in c++.
1802
180323 June 2010: Wouter
1804	- iana portlist updated.
1805	- makedist upgraded cross compile openssl option, like this:

181517 June 2010: Wouter
1816	- Add AAAA to root hints for I.ROOT-SERVERS.NET.
1817
181816 June 2010: Wouter
1819	- Fix assertion failure reported by Kai Storbeck from XS4ALL, the
1820	  assertion was wrong.
1821	- updated ldns tarball.
1822
182315 June 2010: Wouter
1824	- tag 1.4.5 created.
1825	- trunk contains 1.4.6 in development.
1826	- Fix TCPreply on systems with no writev, if just 1 byte could be sent.
1827	- Fix to use one pointer less for iterator query state store_parent_NS.
1828	- makedist crosscompile to windows uses builtin ldns not host ldns.
1829	- Max referral count from 30 to 130, because 128 one character domains
1830	  is valid DNS.
1831	- added documentation for the histogram printout to syslog.
1832
183311 June 2010: Wouter
1834	- When retry to parent the retrycount is not wiped, so failed
1835	  nameservers are not tried again.
1836	- iana portlist updated.
1837
183810 June 2010: Wouter
1839	- Fix bug where a long loop could be entered, now cycle detection
1840	  has a loop-counter and maximum search amount.
1841
18424 June 2010: Wouter
1843	- iana portlist updated.
1844	- 1.4.5rc1 tag created.
1845
18463 June 2010: Wouter
1847	- ldns tarball updated, 1.6.5.
1848	- review comments, split dependency cycle tracking for parentside
1849	  last resort lookups for A and AAAA so there are more lookup options.
1850
18512 June 2010: Wouter
1852	- Fix compile warning if compiled without threads.
1853	- updated ldns-tarball with current ldns svn (pre 1.6.5).
1854	- GOST disabled-by-default, the algorithm number is allocated but the
1855	  RFC is still has to pass AUTH48 at the IETF.
1856
18571 June 2010: Wouter
1858	- Ignore Z flag in incoming messages too.
1859	- Fix storage of negative parent glue if that last resort fails.
1860	- libtoolize 2.2.6b, autoconf 2.65 applied to configure.
1861	- new splint flags for newer splint install.
1862
186331 May 2010: Wouter
1864	- Fix AD flag handling, it could in some cases mistakenly copy the AD
1865	  flag from upstream servers.
1866	- alloc_special_obtain out of memory is not a fatal error any more,
1867	  enabling unbound to continue longer in out of memory conditions.
1868	- parentside names are dispreferred but not said to be dnssec-lame.
1869	- parentside check for cached newname glue.
1870	- fix parentside and querytargets modulestate, for dump_requestlist.
1871	- unbound-control-setup makes keys -rw-r--- so not all users permitted.
1872	- fix parentside from cache to be marked dispreferred for bad names.
1873
187428 May 2010: Wouter
1875	- iana portlist updated.
1876	- parent-child disagreement approach altered.  Older fixes are
1877	  removed in place of a more exhaustive search for misconfigured data
1878	  available via the parent of a delegation.
1879	  This is designed to be throttled by cache entries, with TTL from the
1880	  parent if possible.  Additionally the loop-counter is used.
1881	  It also tests for NS RRset differences between parent and child.
1882	  The fetch of misconfigured data should be more reliable and thorough.
1883	  It should work reliably even with no or only partial data in cache.
1884	  Data received from the child (as always) is deemed more
1885	  authoritative than information received from the delegation parent.
1886	  The search for misconfigured data is not performed normally.
1887
188826 May 2010: Wouter
1889	- Contribution from Migiel de Vos (Surfnet): nagios patch for
1890	  unbound-host, in contrib/ (in the source tarball).  Makes
1891	  unbound-host suitable for monitoring dnssec(-chain) status.
1892
189321 May 2010: Wouter
1894	- EDNS timeout code will not fire if EDNS status already known.
1895	- EDNS failure not stored if EDNS status known to work.
1896
189719 May 2010: Wouter
1898	- Fix resolution for domains like safesvc.com.cn.  If the iterator
1899	  can not recurse further and it finds the delegation in a state
1900	  where it would otherwise have rejected it outhand if so received
1901	  from a cache lookup, then it can try to ask higherup (with loop
1902	  protection).
1903	- Fix comments in iter_utils:dp_is_useless.
1904
190518 May 2010: Wouter
1906	- Fix various compiler warnings from the clang llvm compiler.
1907	- iana portlist updated.

1913	- Fix dnssec-missing detection that was turned off by server selection.
1914	- Conforms to draft-ietf-dnsop-default-local-zones-13.  Added default
1915	  reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
1916	  113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
1917
191829 April 2010: Wouter
1919	- Fix for dnssec lameness detection to use the key cache.
1920	- infra cache entries that are expired are wiped clean.  Previously
1921	  it was possible to not expire host data (if accessed often).
1922
192328 April 2010: Wouter
1924	- ldns tarball updated and GOST support is detected and then enabled.
1925	- iana portlist updated.
1926	- Fix detection of gost support in ldns (reported by Chris Smith).
1927
192827 April 2010: Wouter
1929	- unbound-control get_option domain-insecure shows config file items.
1930	- fix retry sequence if prime hints are recursion-lame.
1931	- autotrust anchor file can be initialized with a ZSK key as well.
1932	- harden-referral-path does not result in failures due to max-depth.
1933	  You can increase the max-depth by adding numbers (' 0') after the
1934	  target-fetch-policy, this increases the depth to which is checked.
1935
193626 April 2010: Wouter
1937	- Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
1938	  CPPFLAGS during configure process.
1939	- if libev is installed on the base system (not libevent), detect
1940	  it from the event.h header file and link with -lev.
1941	- configlexer.lex gets config.h, and configyyrename.h added by make,
1942	  no more double include.
1943	- More strict scrubber (Thanks to George Barwood for the idea):
1944	  NS set must be pertinent to the query (qname subdomain nsname).
1945	- Fix bug#307: In 0x20 backoff fix fallback so the number of
1946	  outstanding queries does not become -1 and block the request.
1947	  Fixed handling of recursion-lame in combination with 0x20 fallback.
1948	  Fix so RRsets are compared canonicalized and sorted if the immediate
1949	  comparison fails, this makes it work around round-robin sites.
1950
195123 April 2010: Wouter
1952	- Squelch log message: sendto failed permission denied for
1953	  255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
1954	- Fix to fetch data as last resort more tenaciously.  When cycle
1955	  targets cause the server selection to believe there are more options
1956	  when they really are not there, the server selection is reinitiated.
1957	- Fix fetch from blacklisted dnssec lame servers as last resort.  The
1958	  server's IP address is then given in validator errors as well.
1959	- Fix local-zone type redirect that did not use the query name for
1960	  the answer rrset.
1961
196222 April 2010: Wouter
1963	- tag 1.4.4.
1964	- trunk contains 1.4.5 in development.
1965	- Fix validation failure for qtype ANY caused by a RRSIG parse failure.
1966	  The validator error message was 'no signatures from ...'.
1967
196816 April 2010: Wouter
1969	- more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
1970	- tag 1.4.4rc1.
1971
197215 April 2010: Wouter
1973	- ECC-GOST algorithm number 12 that is assigned by IANA.  New test
1974	  example key and signatures for GOST.  GOST requires openssl-1.0.0.
1975	  GOST is still disabled by default.
1976
19779 April 2010: Wouter
1978	- Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
1979	  get into an endless loop, if 0x20 was enabled, and buffers are small
1980	  or particular broken packets are received.
1981	- Fix chain of trust with CNAME at an intermediate step, for the DS
1982	  processing proof.
1983
19848 April 2010: Wouter
1985	- Fix validation of queries with wildcard names (*.example).
1986
19876 April 2010: Wouter
1988	- Fix EDNS probe for .de DNSSEC testbed failure, where the infra
1989	  cache timeout coincided with a server update, the current EDNS
1990	  backoff is less sensitive, and does not cache the backoff unless
1991	  the backoff actually works and the domain is not expecting DNSSEC.
1992	- GOST support with correct algorithm numbers.
1993
19941 April 2010: Wouter
1995	- iana portlist updated.
1996
199724 March 2010: Wouter
1998	- unbound control flushed items are not counted when flushed again.
1999
200023 March 2010: Wouter
2001	- iana portlist updated.
2002
200322 March 2010: Wouter
2004	- unbound-host disables use-syslog from config file so that the
2005	  config file for the main server can be used more easily.
2006	- fix bug#301: unbound-checkconf could not parse interface
2007	  '0.0.0.0@5353', even though unbound itself worked fine.
2008
200919 March 2010: Wouter
2010	- fix fwd_ancil test to pass if the socket options are not supported.
2011
201218 March 2010: Wouter
2013	- Fixed random numbers for port, interface and server selection.
2014	  Removed very small bias.
2015	- Refer to the listing in unbound-control man page in the extended
2016	  statistics entry in the unbound.conf man page.
2017
201816 March 2010: Wouter
2019	- Fix interface-automatic for OpenBSD: msg.controllen was too small,
2020	  also assertions on ancillary data buffer.
2021	- check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
2022	- for NSEC3 check if signatures are cached.
2023
202415 March 2010: Wouter
2025	- unit test for util/regional.c.
2026
202712 March 2010: Wouter
2028	- Reordered configure checks so fork and -lnsl -lsocket checks are
2029	  earlier, and thus later checks benefit from and do not hinder them.
2030	- iana portlist updated.
2031	- ldns tarball updated.
2032	- Fix python use when multithreaded.
2033	- Fix solaris python compile.
2034	- Include less in config.h and include per code file for ldns, ssl.
2035
203611 March 2010: Wouter
2037	- another memory allocation option: --enable-alloc-nonregional.
2038	  exposes the regional allocations to other memory purifiers.
2039	- fix for memory alignment in struct sock_list allocation.
2040	- Fix for MacPorts ldns without ssl default, unbound checks if ldns
2041	  has dnssec functionality and uses the builtin if not.
2042	- Fix daemonize on Solaris 10, it did not detach from terminal.
2043	- tag 1.4.3 created.
2044	- trunk is 1.4.4 in development.
2045	- spelling fix in validation error involving cnames.
2046
204710 March 2010: Wouter

2049	- portability in the testset: printf format conversions, prototypes.
2050
20519 March 2010: Wouter
2052	- tag 1.4.2 created.
2053	- trunk is 1.4.3 in development.
2054	- --enable-alloc-lite debug option.
2055
20568 March 2010: Wouter
2057	- iana portlist updated.
2058
20594 March 2010: Wouter

2064	- iana portlist updated.
2065
20661 March 2010: Wouter
2067	- make install depends on make all.
2068	- Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
2069	- --enable-checking: enables assertions but does not look nonproduction.
2070	- nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
2071	  nxdomain and nodata distinguished.
2072	- ldns tarball updated.
2073	- --disable-rpath fixed for libtool not found errors.
2074	- new fedora specfile from Fedora13 in contrib from Paul Wouters.
2075
207626 February 2010: Wouter
2077	- Fixup prototype for lexer cleanup in daemon code.
2078	- unbound-control list_stubs, list_forwards, list_local_zones and
2079	  list_local_data.
2080
208124 February 2010: Wouter
2082	- Fix scrubber bug that potentially let NS records through.  Reported
2083	  by Amanda Constant.
2084	- Also delete potential poison references from additional.
2085	- Fix: no classification of a forwarder as lame, throw away instead.
2086
208723 February 2010: Wouter
2088	- libunbound ub_ctx_get_option() added.
2089	- unbound-control set_option and get_option commands.
2090	- iana portlist updated.
2091
209218 February 2010: Wouter
2093	- A little more strict DS scrubbing.
2094	- No more blacklisting of unresponsive servers, a 2 minute timeout
2095	  is backed off to.
2096	- RD flag not enabled for dnssec-blacklisted tries, unless necessary.
2097	- pickup ldns compile fix, libdl for libcrypto.
2098	- log 'tcp connect: connection timed out' only in high verbosity.
2099	- unbound-control log_reopen command.
2100	- moved get_option code from unbound-checkconf to util/config_file.c
2101
210217 February 2010: Wouter
2103	- Disregard DNSKEY from authority section for chain of trust.
2104	  DS records that are irrelevant to a referral scrubbed.  Anti-poison.
2105	- iana portlist updated.
2106
210716 February 2010: Wouter
2108	- Check for 'no space left on device' (or other errors) when
2109	  writing updated autotrust anchors and print errno to log.
2110
211115 February 2010: Wouter
2112	- Fixed the requery protection, the TTL was 0, it is now 900 seconds,
2113	  hardcoded.  We made the choice to send out more conservatively,
2114	  protecting against an aggregate effect more than protecting a
2115	  single user (from their own folly, perhaps in case of misconfig).
2116
211712 February 2010: Wouter
2118	- Re-query pattern changed on validation failure.  To protect troubled
2119	  authority servers, unbound caches a failure for the DNSKEY or DS
2120	  records for the entire zone, and only retries that 900 seconds later.
2121	  This implies that only a handful of packets are sent extra to the
2122	  authority if the zone fails.
2123
212411 February 2010: Wouter
2125	- ldns tarball update for long label length syntax error fix.
2126	- iana portlist updated.
2127
21289 February 2010: Wouter
2129	- Fixup in compat snprintf routine, %f 1.02 and %g support.
2130	- include math.h for testbound test compile portability.
2131
21322 February 2010: Wouter
2133	- Updated url of IANA itar, interim trust anchor repository, in script.
2134
21351 February 2010: Wouter
2136	- iana portlist updated.
2137	- configure test for memcmp portability.
2138
213927 January 2010: Wouter
2140	- removed warning on format string in validator error log statement.
2141	- iana portlist updated.
2142
214322 January 2010: Wouter
2144	- libtool finish the install of unbound python dynamic library.
2145
214621 January 2010: Wouter
2147	- acx_nlnetlabs.m4 synchronised with nsd's version.
2148
214920 January 2010: Wouter
2150	- Fixup lookup trouble for parent-child domains on the first query.
2151
215214 January 2010: Wouter
2153	- Fixup ldns detection to also check for header files.
2154
215513 January 2010: Wouter
2156	- prefetch-key option that performs DNSKEY queries earlier in the
2157	  validation process, and that could halve the latency on DNSSEC
2158	  queries.  It takes some extra processing (CPU, a cache is needed).
2159
216012 January 2010: Wouter
2161	- Fix unbound-checkconf for auto-trust-anchor-file present checks.
2162
21638 January 2010: Wouter
2164	- Fix for parent-child disagreement code which could have trouble
2165	  when (a) ipv6 was disabled and (b) the TTL for parent and child
2166	  were different.  There were two bugs, the parent-side information
2167	  is fixed to no longer block lookup of child side information and
2168	  the iterator is fixed to no longer attempt to get ipv6 when it is
2169	  not enabled and then give up in failure.
2170	- test and fixes to make prefetch actually store the answer in the
2171	  cache.  Considers some rrsets 'already expired' but does not allow
2172	  overwriting of rrsets considered more secure.
2173
21747 January 2010: Wouter
2175	- Fixup python documentation (thanks Leo Vandewoestijne).
2176	- Work on cache prefetch feature.
2177	- Stats for prefetch, in log print stats, unbound-control stats
2178	  and in unbound_munin plugin.
2179
21806 January 2010: Wouter
2181	- iana portlist updated.
2182	- bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.
2183	- verbose output includes parent-side-address notion for lameness.
2184	- documented val-log-level: 2 setting in example.conf and man page.
2185	- change unbound-control-setup from 1024(sha1) to 1536(sha256).
2186
21871 January 2010: Wouter
2188	- iana portlist updated.
2189
219022 December 2009: Wouter
2191	- configure with newer libtool 2.2.6b.
2192
219317 December 2009: Wouter
2194	- review comments.
2195	- tag 1.4.1.
2196	- trunk to version 1.4.2.
2197
219815 December 2009: Wouter
2199	- Answer to qclass=ANY queries, with class IN contents.
2200	  Test that validation also works.
2201	- updated ldns snapshot tarball with latest fixes (parsing records).
2202
220311 December 2009: Wouter
2204	- on IPv4 UDP turn off DF flag.
2205
220610 December 2009: Wouter
2207	- requirements.txt updated with design choice explanations.
2208	- Reading fixes: fix to set unlame when child confirms parent glue,
2209	  and fix to avoid duplicate addresses in delegation point.
2210	- verify_rrsig routine checks expiration last.
2211
22129 December 2009: Wouter
2213	- Fix Bug#287(reopened): update of ldns tarball with fix for parse
2214	  errors generated for domain names like '.example.com'.
2215	- Fix SOA excluded from negative DS responses.  Reported by Hauke
2216	  Lampe.  The negative cache did not include proper SOA records for
2217	  negative qtype DS responses which makes BIND barf on it, such
2218	  responses are now only used internally.
2219	- Fix negative cache lookup of closestencloser check of DS type bit.
2220
22218 December 2009: Wouter
2222	- Fix for lookup of parent-child disagreement domains, where the
2223	  parent-side glue works but it does not provide proper NS, A or AAAA
2224	  for itself, fixing domains such as motorcaravanners.eu.
2225	- Feature: you can specify a port number in the interface: line, so
2226	  you can bind the same interface multiple times at different ports.
2227
22287 December 2009: Wouter
2229	- Bug#287: Fix segfault when unbound-control remove nonexistent local
2230	  data.  Added check to tests.
2231
22321 December 2009: Wouter
2233	- Fix crash with module-config "iterator".
2234	- Added unit test that has "iterator" module-config.
2235
223630 November 2009: Wouter
2237	- bug#284: fix parse of # without end-of-line at end-of-file.

2241	- tag for 1.4.0 release.
2242	- 1.4.1 version in trunk.
2243	- Fixup major libtool version to 2 because of why_bogus change.
2244	  It was 1:5:0 but should have been 2:0:0.
2245
224623 November 2009: Wouter
2247	- Patch from David Hubbard for libunbound manual page.
2248	- Fixup endless spinning in unbound-control stats reported by
2249	  Attila Nagy.  Probably caused by clock reversal.
2250
225120 November 2009: Wouter
2252	- contrib/split-itar.sh contributed by Tom Hendrikx.
2253
225419 November 2009: Wouter

2265	- Tests for CNAMEs to deeper trust anchors, secure and bogus.
2266	- svn tag 1.4.0rc1 made.
2267
226813 November 2009: Wouter
2269	- Fixed validation failure for CNAME to optout NSEC3 nodata answer.
2270	- unbound-host does not fail on type ANY.
2271	- Fixed wireparse failure to put RRSIGs together with data in some
2272	  long ANY mix cases, which fixes validation failures.
2273
227412 November 2009: Wouter
2275	- iana portlist updated.
2276	- fix manpage errors reported by debian lintian.
2277	- review comments.
2278	- fixup very long vallog2 level error strings.
2279
228011 November 2009: Wouter
2281	- ldns tarball updated (to 1.6.2).
2282	- review comments.
2283
228410 November 2009: Wouter
2285	- Thanks to Surfnet found bug in new dnssec-retry code that failed
2286	  to combine well when combined with DLV and a particular failure.
2287	- Fixed unbound-control -h output about argument optionality.
2288	- review comments.
2289
22905 November 2009: Wouter
2291	- lint fixes and portability tests.
2292	- better error text for multiple domain keys in one autotrust file.
2293
22942 November 2009: Wouter
2295	- Fix bug where autotrust does not work when started with a DS.
2296	- Updated GOST unit tests for unofficial algorithm number 249
2297	  and DNSKEY-format changes in draft version -01.
2298
229929 October 2009: Wouter
2300	- iana portlist updated.
2301	- edns-buffer-size option, default 4096.
2302	- fixed do-udp: no.
2303
230428 October 2009: Wouter

2306	- iana portlist updated.
2307	- RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
2308	- ldns tarball updated (which also enables rsasha256 support).
2309
231027 October 2009: Wouter
2311	- iana portlist updated.
2312
23138 October 2009: Wouter
2314	- please doxygen
2315	- add val-log-level print to corner case (nameserver.epost.bg).
2316	- more detail to errors from insecure delegation checks.
2317	- Fix double time subtraction in negative cache reported by
2318	  Amanda Constant and Hugh Mahon.
2319	- Made new validator error string available from libunbound for
2320	  applications.  It is in result->why_bogus, a zero-terminated string.
2321	  unbound-host prints it by default if a result is bogus.
2322	  Also the errinf is public in module_qstate (for other modules).
2323
23247 October 2009: Wouter
2325	- retry for validation failure in DS and prime results. Less mem use.
2326	  unit test.  Provisioning in other tests for requeries.
2327	- retry for validation failure in DNSKEY in middle of chain of trust.
2328	  unit test.
2329	- retry for empty non terminals in chain of trust and unit test.
2330	- Fixed security bug where the signatures for NSEC3 records were not
2331	  checked when checking for absence of DS records.  This could have
2332	  enabled the substitution of an insecure delegation.
2333	- moved version number to 1.4.0 because of 1.3.4 release with only
2334	  the NSEC3 patch from the entry above.
2335	- val-log-level: 2 shows extended error information for validation
2336	  failures, but still one (longish) line per failure.  For example:
2337	  validation failure <example.com. DNSKEY IN>: signature expired from
2338	  192.0.2.4 for trust anchor example.com. while building chain of trust
2339	  validation failure <www.example.com. A IN>: no signatures from
2340	  192.0.2.6 for key example.com. while building chain of trust
2341
23426 October 2009: Wouter
2343	- Test set updated to provide additional ns lookup result.
2344	  The retry would attempt to fetch the data from other nameservers
2345	  for bogus data, and this needed to be provisioned in the tests.
2346
23475 October 2009: Wouter
2348	- first validation failure retry code.  Retries for data failures.
2349	  And unit test.
2350
23512 October 2009: Wouter
2352	- improve 5011 modularization.
2353	- fix unbound-host so -d can be given before -C.
2354	- iana portlist updated.
2355
235628 September 2009: Wouter
2357	- autotrust-anchor-file can read multiline input and $ORIGIN.
2358	- prevent integer overflow in holddown calculation. review fixes.
2359	- fixed race condition in trust point revocation. review fix.
2360	- review fixes to comments, removed unused code.

2371	- test unbound reading of original autotrust data.
2372	  The metadata per-key, such as key state (PENDING, MISSING, VALID) is
2373	  picked up, otherwise performs initial probe like usual.
2374
237522 September 2009: Wouter
2376	- autotrust test with algorithm rollover, new ordering of checks
2377	  assists in orderly rollover.

240110 September 2009: Wouter
2402	- increased MAXSYSLOGLEN so .bg key can be printed in debug output.
2403	- use linebuffering for log-file: output, this can be significantly
2404	  faster than the previous fflush method and enable some class of
2405	  resolvers to use high verbosity (for short periods).
2406	  Not on windows, because line buffering does not work there.
2407
24089 September 2009: Wouter
2409	- Fix bug where DNSSEC-bogus messages were marked with too high TTL.
2410	  The RRsets would still expire at the normal time, but this would

2413	- documented that load_cache is meant for debugging.
2414

2629	  structures so that later validation would fail.
2630	- Extreme lenience for wrongly truncated replies where a positive
2631	  reply has an NS in the authority but no signatures.  They are
2632	  turned into minimal responses with only the (secure) answer.
2633	- autoconf 2.63 for configure.
2634	- python warnings suppress.  Keep python API away from header files.

2642	  generate queries that are known to fail.
2643	- Touchup on munin total memory report.
2644	- messages picked out of the cache by the iterator are checked
2645	  if their cname chain is still correct and if validation status
2646	  has to be reexamined.
2647
264815 June 2009: Wouter
2649	- iana portlist updated.
2650
265114 June 2009: Wouter

2663	- fwd above stub in configuration works.
2664
266511 June 2009: Wouter
2666	- Fix queries for type DS when forward or stub zones are there.
2667	  They are performed to higherup domains, and thus treated as if
2668	  going to higher zones when looking up the right forward or stub
2669	  server.  This makes a stub pointing to a local server that has
2670	  a local view of example.com signed with the same keys as are
2671	  publicly used work.  Reported by Johan Ihren.
2672	- Added build-unbound-localzone-from-hosts.pl to contrib, from
2673	  Dennis DeDonatis.  It converts /etc/hosts into config statements.
2674	- same thing fixed for forward-zone and DS, chain of trust from
2675	  public internet into the forward-zone works now.  Added unit test.
2676
26779 June 2009: Wouter
2678	- openssl key files are opened apache-style, when user is root and
2679	  before chrooting.  This makes permissions on remote-control key
2680	  files easier to set up.  Fixes bug #251.
2681	- flush_type and flush_name remove msg cache entries.
2682	- codereview - dp copy bogus setting fix.
2683
26848 June 2009: Wouter
2685	- Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
2686	  inadvertant behaviour.
2687	- 1.3.0 tarball for release created.
2688	- 1.3.1 development in svn trunk.

2697	  Reported by Paul Wouters.
2698	- review comments from Matthijs.
2699
27002 June 2009: Wouter
2701	- --enable-sha2 option. The draft rsasha256 changed its algorithm
2702	  numbers too often.  Therefore it is more prudent to disable the
2703	  RSASHA256 and RSASHA512 support by default.
2704	- ldns trunk included as new tarball.
2705	- recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.

2713
271427 May 2009: Wouter
2715	- detect lack of IPv6 support on XP (with a different error code).
2716	- Fixup a crash-on-exit which was triggered by a very long queue.
2717	  Unbound would try to re-use ports that came free, but this is
2718	  of course not really possible because everything is deleted.
2719	  Most easily triggered on XP (not Vista), maybe because of the
2720	  network stack encouraging large messages backlogs.
2721	- change in debug statements.
2722	- Fixed bug that could cause a crash if root prime failed when there
2723	  were message backlogs.
2724
272526 May 2009: Wouter
2726	- Thanks again to Brett Carr, found an assertion that was not true.
2727	  Assertion checked if recursion parent query still existed.
2728
272929 April 2009: Wouter
2730	- Thanks to Brett Carr, caught windows resource leak, use
2731	  closesocket() and not close() on sockets or else the network stack
2732	  starts to leak handles.
2733	- Removed usage of windows Mutex because windows cannot handle enough
2734	  mutexes open.  Provide own mutex implementation using primitives.
2735
273628 April 2009: Wouter
2737	- created svn tag for 1.3.0.

2753	- fix for configure script swig detection.
2754
275517 April 2009: Wouter

2760	- fix rsasha512 unit test for new (interim) algorithm number.
2761	- fix test:ldns doesn't like DOS line endings in keyfiles on unix.

2779	- ldns tarball updated.
2780	- iana portlist update.
2781	- detect GOST support in openssl-1.0.0-beta1, and fix compile problem
2782	  because that openssl defines the name STRING for itself.
2783
27846 April 2009: Wouter
2785	- windows compile fix.
2786	- Detect FreeBSD jail without ipv6 addresses assigned.
2787	- python libunbound wrapper unit test.

2790	  /usr/lib/python2.x/site-packages/unboundmodule.py
2791	  	from configure --with-pyunbound:
2792	  /usr/lib/python2.x/site-packages/unbound.py
2793	  /usr/lib/python2.x/site-packages/_unbound.so*
2794	  The example python scripts (pythonmod/examples and

2799
28003 April 2009: Wouter
2801	- Fixed a bug that caused messages to be stored in the cache too
2802	  long.  Hard to trigger, but NXDOMAINs for nameservers or CNAME
2803	  targets have been more vulnerable to the TTL miscalculation bug.
2804	- documentation test fixed for python addition.
2805
28062 April 2009: Wouter
2807	- pyunbound (libunbound python plugin) compiles using libtool.
2808	- documentation for pythonmod and pyunbound is generated in doc/html.
2809	- iana portlist updated.
2810	- fixed bug in unbound-control flush_zone where it would not flush
2811	  every message in the target domain.  This especially impacted
2812	  NXDOMAIN messages which could remain in the cache regardless.
2813	- python module test package.
2814
28151 April 2009: Wouter
2816	- suppress errors when trying to contact authority servers that gave
2817	  ipv6 AAAA records for their nameservers with ipv4 mapped contents.
2818	  Still tries to do so, could work when deployed in intranet.
2819	  Higher verbosity shows the error.
2820	- new libunbound calls documented.
2821	- pyunbound in libunbound/python. Removed compile warnings.
2822	  Makefile to make it.
2823

2874	- Added tests, unknown algorithms become insecure. fallback works.
2875	- Fix for and test for unknown algorithms in a trust anchor
2876	  definition.  Trust anchors with no supported algos are ignored.
2877	  This means a (higher)DS or DLV entry for them could succeed, and
2878	  otherwise they are treated as insecure.
2879	- domain-insecure: "example.com" statement added. Sets domain

296119 February 2009: Wouter
2962	- unbound-checkconf and unbound print warnings when trust anchors
2963	  have unsupported algorithms.
2964	- added contrib/update-itar.sh  This script is similar to
2965	  update-anchor.sh, and updates from the IANA ITAR repository.
2966	  You can provide your own PGP key and trust repo, or can use the
2967	  builtin.  The program uses wget and gpg to work.
2968	- iana portlist updated.
2969	- update-itar.sh: using ftp:// urls because https godaddy certificate
2970	  is not available everywhere and then gives fatal errors.  The
2971	  security is provided by pgp signature.
2972
297318 February 2009: Wouter
2974	- more cycle detection. Also for target queries.
2975	- fixup bug where during deletion of the mesh queries the callbacks
2976	  that were reentrant caused assertion failures. Keep the mesh in
2977	  a reentrant safe state.  Affects libunbound, reload of server,
2978	  on quit and flush_requestlist.
2979	- iana portlist updated.
2980
298113 February 2009: Wouter
2982	- forwarder information now per-thread duplicated.
2983	  This keeps it read only for speed, with no locking necessary.

2985	  on the fly.
2986	- document that unbound-host reads no config file by default.
2987	- updated iana portlist.
2988

3000	- keys with rfc5011 REVOKE flag are skipped and not considered when
3001	  validating data.
3002	- iana portlist updated
3003	- #226: dump_requestlist feature for unbound-control.

3007	- iana portlist updated.
3008	- fixup EOL in include directive (reported by Paul Wouters).
3009	  You can no longer specify newlines in the names of included files.
3010	- config parser changed. Gives some syntax errors closer to where they
3011	  occurred. Does not enforce a space after keyword anymore.
3012	  Does not allow literal newlines inside quoted strings anymore.
3013	- verbosity level 5 logs customer IP for new requestlist entries.
3014	- test fix, lexer and cancel test.
3015	- new option log-time-ascii: yes  if you enable it prints timestamps
3016	  in the log file as Feb 06 13:45:26 (like syslog does).
3017	- detect event_base_new in libevent-1.4.1 and later and use it.
3018	- #231 unbound-checkconf -o option prints that value from config file.
3019	  Useful for scripting in management scripts and the like.
3020
30215 February 2009: Wouter
3022	- ldns 1.5.0 rc as tarball included.
3023	- 1.3.0 development continues:
3024	  change in libunbound API: ub_cancel can return an error, that
3025	  the async_id did not exist, or that it was already delivered.
3026	  The result could have been delivered just before the cancel
3027	  routine managed to acquire the lock, so a caller may get the
3028	  result at the same time they call cancel.  For this case,
3029	  ub_cancel tries to return an error code.
3030	  Fixes race condition in ub_cancel() libunbound function.
3031	- MacOSX Leopard cleaner text output from configure.
3032	- initgroups(3) is called to drop secondary group permissions, if
3033	  applicable.
3034	- configure option --with-ldns-builtin forces the use of the
3035	  inluded ldns package with the unbound source.  The -I include
3036	  is put before the others, so it avoids bad include files from
3037	  an older ldns install.
3038	- daemon(3) posix call is used when available.
3039	- testbound test for older fix added.
3040
30414 February 2009: Wouter
3042	- tag for release 1.2.1.
3043	- trunk setup for 1.3.0 development.
3044
30453 February 2009: Wouter
3046	- noted feature requests in doc/TODO.
3047	- printout more detailed errors on ssl certificate loading failures.
3048	- updated IANA portlist.
3049
305016 January 2009: Wouter
3051	- more quiet about ipv6 network failures, i.e. when ipv6 is not
3052	  available (network unreachable). Debug still printed on high
3053	  verbosity.
3054	- unbound-host -4 and -6 options. Stops annoying ipv6 errors when
3055	  debugging with unbound-host -4 -d ...
3056	- more cycle detection for NS-check, addr-check, root-prime and
3057	  stub-prime queries in the iterator.  Avoids possible deadlock
3058	  when priming fails.
3059
306015 January 2009: Wouter
3061	- bug #229: fixup configure checks for compilation with Solaris
3062	  Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc

3064	- fix bug where unbound could crash using libevent 1.3 and older.
3065	- update testset for recent retry change.
3066
306714 January 2009: Wouter
3068	- 1.2.1 feature: negative caching for failed queries.
3069	  Queries that failed are cached for 5 seconds (NORR_TTL).
3070	  If the failure is local, like out of memory, it is not cached.
3071	- the TTL comparison for the cache used different comparisons,
3072	  causing many cache responses that used the iterator and validator
3073	  state machines unnecessarily.
3074	- retry from 4 to 5 so that EDNS drop retry is part of the first
3075	  query resolve attempt, and cached error does not stop EDNS fallback.
3076	- remove debug prints that protect against bad referrals.
3077	- honor QUIET=no on make commandline (or QUIET=yes ).
3078
307913 January 2009: Wouter
3080	- fixed bug in lameness marking, removed printouts.
3081	- find NS rrset more cleanly for qtype NS.
3082	- Moved changes to 1.2.0 for release. Thanks to Mark Zealey for
3083	  reporting and logs.

3085	  are in the negative cache.
3086
308712 January 2009: Wouter
3088	- fixed bug in infrastructure lameness cache, did not lowercase

3104	- version 1.2.0 in preparation.
3105	- feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
3106	  statements. (Adapted from patch by Paul Wouters).
3107	- typo fix and iana portlist updated.
3108	- porting testsuite; unused var warning, and type fixup.
3109
31106 January 2009: Wouter
3111	- fixup packet-of-death when compiled with --enable-debug.
3112	  A malformed packet could cause an internal assertion failure.
3113	- added test for HINFO canonicalisation behaviour.
3114	- fixup reported problem with transparent local-zone data where
3115	  queries with different type could get nxdomain. Now queries
3116	  with a different name get resolved normally, with different type
3117	  get a correct NOERROR/NODATA answer.
3118	- HINFO no longer downcased for validation, making unbound compatible
3119	  with bind and ldns.
3120	- fix reading included config files when chrooted.
3121	  Give full path names for include files.
3122	  Relative path names work if the start dir equals the working dir.
3123	- fix libunbound message transport when no packet buffer is available.
3124
31255 January 2009: Wouter
3126	- fixup getaddrinfo failure handling for remote control port.

3129	- comm_timer_set performs base_set operation after event_add.
3130

3132	- fixed bug reported by Duane Wessels: error in DLV lookup, would make
3133	  some zones that had correct DLV keys as insecure.
3134	- follows -rc makedist from ldns changes (no _rc).
3135	- ldns tarball updated with 1.4.1rc for DLV unit test.
3136	- verbose prints about recursion lame detection and server selection.
3137	- fixup BSD port for infra host storage. It hashed wrongly.
3138	- fixup makedist snapshot name generation.
3139	- do not reopen syslog to avoid dev/log dependency.
3140
314117 December 2008: Wouter
3142	- follows ldns makedist.sh. -rc option. autom4te dir removed.
3143	- unbound-control status command.
3144	- extended statistics has a number of ipv6 queries counter.
3145	  contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
3146
314716 December 2008: Wouter
3148	- follow makedist improvements from ldns, for maintainers prereleases.
3149	- snapshot version uses _ not - to help rpm distinguish the
3150	  version number.

3159	- iana portlist updated.
3160
31613 December 2008: Wouter
3162	- Fix problem reported by Jaco Engelbrecht where unbound-control stats
3163	  freezes up unbound if this was compiled without threading, and
3164	  was using multiple processes.
3165	- iana portlist updated.
3166	- test for remote control with interprocess communication.
3167	- created command distribution mechanism so that remote control
3168	  commands other than 'stats' work on all processes in a nonthreaded
3169	  compiled version. dump/load cache work, on the first process.
3170	- fixup remote control local_data addition memory corruption bug.
3171
31721 December 2008: Wouter
3173	- SElinux policy files in contrib/selinux for the unbound daemon,
3174	  by Paul Wouters and Adam Tkac.
3175
317625 November 2008: Wouter
3177	- configure complains when --without-ssl is given (bug #220).
3178	- skip unsupported feature tests on vista/mingw.
3179	- fixup testcode/streamtcp to work on vista/mingw.
3180	- root-hints test checks version of dig required.
3181	- blacklisted servers are polled at a low rate (1%) to see if they
3182	  come back up. But not if there is some other working server.
3183
318424 November 2008: Wouter
3185	- document that the user of the server daemon needs read privileges
3186	  on the keys and certificates generated by unbound-control-setup.
3187	  This is different per system or distribution, usually, running the
3188	  script under the same username as the server uses suffices.
3189	  i.e.  sudo -u unbound unbound-control-setup
3190	- testset port to vista/mingw.
3191	- tcp_sigpipe to freebsd port.
3192
319321 November 2008: Wouter
3194	- fixed tcp accept, errors were printed when they should not.
3195	- unbound-control-setup.sh removes read/write permissions other
3196	  from the keys it creates (as suggested by Dmitriy Demidov).
3197
319820 November 2008: Wouter
3199	- fixup fatal error due to faulty error checking after tcp accept.
3200	- add check in rlimit to avoid integer underflow.
3201	- rlimit check with new formula; better estimate for number interfaces
3202	- nicer comments in rlimit check.

3204	- trunk label is 1.1.2
3205
320619 November 2008: Wouter

3216
321717 November 2008: Wouter
3218	- theoretical fix for problems reported on mailing list.
3219	  If a delegation point has no A but only AAAA and do-ip6 is no,
3220	  resolution would fail. Fixed to ask for the A and AAAA records.
3221	  It has to ask for both always, so that it can fail quietly, from
3222	  TLD perspective, when a zone is only reachable on one transport.
3223	- test for above, only AAAA and doip6 is no. Fix causes A record
3224	  for nameserver to be fetched.
3225	- fixup address duplication on cache fillup for delegation points.
3226	- testset updated for new query answer requirements.
3227

32675 November 2008: Wouter
3268	- fixed possible memory leak in key_entry_key deletion.
3269	  Would leak a couple bytes when trust anchors were replaced.
3270	- if query and reply qname overlap, the bytes are skipped not copied.
3271	- fixed file descriptor leak when messages were jostled out that
3272	  had outstanding (TCP) replies.
3273	- DNAMEs used from cache have their synthesized CNAMEs initialized
3274	  properly.
3275	- fixed file descriptor leak for localzone type deny (for TCP).
3276	- fixed memleak at exit for nsec3 negative cached zones.
3277	- fixed memleak for the keyword 'nodefault' when reading config.
3278	- made verbosity of 'edns incapable peer' warning higher, so you
3279	  do not get spammed by it.
3280	- caught elusive Bad file descriptor error bug, that would print the
3281	  error while unnecessarily try to listen to a closed fd. Fixed.
3282
32834 November 2008: Wouter
3284	- fixed -Wwrite-strings warnings that result in better code.
3285
32863 November 2008: Wouter
3287	- fixup build process for Mac OSX linker, use ldns b32 compat funcs.
3288	- generated configure with autoconf-2.61.
3289	- iana portlist updated.
3290	- detect if libssl needs libdl.  For static linking with libssl.
3291	- changed to use new algorithm identifiers for sha256/sha512
3292	  from ldns 1.4.0 (need very latest version).
3293	- updated the included ldns tarball.
3294	- proper detection of SHA256 and SHA512 functions (not just sizes).
3295
329623 October 2008: Wouter
3297	- a little more debug info for failure on signer names. prints names.
3298
329922 October 2008: Wouter
3300	- CFLAGS are picked up by configure from the environment.
3301	- iana portlist updated.
3302	- updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
3303	- new stub-prime: yesno option. Default is off, so it does not prime.
3304	  can be turned on to get same behaviour as previous unbound release.
3305	- made automated test that checks if builtin root hints are uptodate.
3306	- finished draft-wijngaards-dnsext-resolver-side-mitigation
3307	  implementation. The unwanted-reply-threshold can be set.
3308	- fixup so fptr_whitelist test in alloc.c works.
3309
331021 October 2008: Wouter
3311	- fix update-anchors.sh, so it does not report different RR order
3312	  as an update.  Sorts the keys in the file.  Updated copyright.
3313	- fixup testbound on windows, the command control pipe doesn't exist.
3314	- skip 08hostlib test on windows, no fork() available.
3315	- made unbound-remote work on windows.
3316
331720 October 2008: Wouter
3318	- quench a log message that is debug only.
3319	- iana portlist updated.
3320	- do not query bogus nameservers.  It is like nameservers that have
3321	  the NS or A or AAAA record bogus are listed as donotquery.
3322	- if server selection is faced with only bad choices, it will
3323	  attempt to get more options to be fetched.
3324	- changed bogus-ttl default value from 900 to 60 seconds.
3325	  In anticipation that operator caused failures are more likely than
3326	  actual attacks at this time.  And thus repeated validation helps
3327	  the operators get the problem fixed sooner.  It makes validation
3328	  failures go away sooner (60 seconds after the zone is fixed).
3329	  Also it is likely to try different nameserver targets every minute,
3330	  so that if a zone is bad on one server but not another, it is
3331	  likely to pick up the 'correct' one after a couple minutes,
3332	  and if the TTL is big enough that solves validation for the zone.
3333	- fixup unbound-control compilation on windows.
3334
333517 October 2008: Wouter
3336	- port Leopard/G5: fixup type conversion size_t/uint32.
3337	  please ranlib, stop file without symbols warning.
3338	- harden referral path now also validates the root after priming.
3339	  It looks up the root NS authoritatively as well as the root servers
3340	  and attemps to validate the entries.
3341
334216 October 2008: Wouter
3343	- Fixup negative TTL values appearing (reported by Attila Nagy).
3344
334515 October 2008: Wouter
3346	- better documentation for 0x20; remove fallback TODO, it is done.
3347	- harden-referral-path feature includes A, AAAA queries for glue,
3348	  as well as very careful NS caching (only when doing NS query).
3349	  A, AAAA use the delegation from the NS-query.
3350
335114 October 2008: Wouter
3352	- fwd_three.tpkg test was flaky.  If the three requests hit the
3353	  wrong threads by chance (or bad OS) then the test would fail.
3354	  Made less flaky by increasing number of retries.
3355	- stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
3356	- ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
3357	  Which includes the ldns_dname_absolute fix.
3358	- fwd_three test remains flaky now that unbound does not stop
3359	  listening when full.  Thus, removed timeout problem.
3360	  It may be serviced by three threads, or maybe by one.
3361	  Mostly only useful for lock-check testing now.
3362
336313 October 2008: Wouter
3364	- fixed recursion servers deployed as authoritative detection, so
3365	  that as a last resort, a +RD query is sent there to get the
3366	  correct answer.
3367	- iana port list update.
3368	- ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
3369
337010 October 2008: Wouter
3371	- fixup tests - the negative cache contained the correct NSEC3s for
3372	  two tests that are supposed to fail to validate.
3373
33749 October 2008: Wouter
3375	- negative cache caps max iterations of NSEC3 done.
3376	- NSEC3 negative cache for qtype DS works.

33816 October 2008: Wouter
3382	- jostle-timeout option, so you can config for slow links.
3383	- 0x20 fallback code.  Tries 3xnumber of nameserver addresses
3384	  queries that must all be the same.  Sent to random nameservers.
3385	- documented choices for DoS, EDNS, 0x20.
3386
33872 October 2008: Wouter
3388	- fixup unlink of pidfile.
3389	- fixup SHA256 algorithm collation code.
3390	- contrib/update-anchor.sh does not overwrite anchors if not needed.
3391	  exits 0 when a restart is needed, other values if not.
3392	  so,  update-anchor.sh -d mydir && /etc/rc.d/unbound restart
3393	  can restart unbound exactly when needed.
3394
339530 September 2008: Wouter
3396	- fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
3397	- tests for sha256 support and downgrade resistance.
3398	- RSASHA256 and RSASHA512 support (using the draft in dnsext),
3399	  using the drafted protocol numbers.
3400	- when using stub on localhost (127.0.0.1@10053) unbound works.
3401	  Like when running NSD to host a local zone, on the same machine.
3402	  The noprime feature. manpages more explanation. Added a test for it.
3403	- shorthand for reverse PTR,  local-data-ptr: "1.2.3.4 www.ex.com"
3404
340529 September 2008: Wouter
3406	- EDNS lameness detection, if EDNS packets are dropped this is
3407	  detected, eventually.
3408	- multiple query timeout rtt backoff does not backoff too much.
3409

34901 September 2008: Wouter
3491	- disallow nonrecursive queries for cache snooping by default.
3492	  You can allow is using access-control: <subnet> allow_snoop.
3493	  The defaults do allow access no authoritative data without RD bit.
3494	- two tests for it and fixups of tests for nonrec refused.
3495
349629 August 2008: Wouter
3497	- version 1.1 number in trunk.
3498	- harden-referral-path option for query for NS records.
3499	  Default turns off expensive, experimental option.
3500
350128 August 2008: Wouter
3502	- fixup logfile handling; it is created with correct permissions
3503	  again. (from bugfix#199).
3504	  Some errors are not written to logfile (pidfile writing, forking),
3505	  and these are only visible by using the -d commandline flag.
3506
350727 August 2008: Wouter
3508	- daemon(3) is causing problems for people. Reverting the patch.
3509	  bug#200, and 199 and 203 contain sideline discussion on it.
3510	- bug#199 fixed: pidfile can be outside chroot. openlog is done before
3511	  chroot and drop permissions.
3512	- config option to set size of aggressive negative cache,
3513	  neg-cache-size.
3514	- bug#203 fixed: dlv has been implemented.

3568
356911 August 2008: Wouter
3570	- Fixup rrset security updates overwriting 2181 trust status.
3571	  This makes validated to be insecure data just as worthless as
3572	  nonvalidated data, and 2181 rules prevent cache overwrites to them.
3573	- Fix assertion fail on bogus key handling.
3574	- dnssec lameness detection works on first query at trust apex.
3575	- NS queries get proper cache and dnssec lameness treatment.

3602	- created tube signaling solution on windows, as a pipe replacement.
3603	  this makes background asynchronous resolution work on windows.
3604	- removed very insecure socketpair compat code. It also did not
3605	  work with event_waiting. Solved by pipe replacement.
3606	- unbound -h prints openssl version number as well.
3607
360822 July 2008: Wouter

3627	  fds than the builtin minievent can handle.
3628
362916 July 2008: Wouter
3630	- made svn tag 1.0.1, trunk now 1.0.2

3652	- fixup unit test for infra cache, test lame merging.
3653	- porting to mingw, bind, listen, getsockopt and setsockopt error
3654	  handling.
3655
365624 June 2008: Wouter
3657	- removed testcode/checklocks from production code compilation path.

3659	  on windows.
3660	- fwd_ancil test fails if platform support is lacking.
3661
366223 June 2008: Wouter
3663	- fixup minitpkg to cleanup on windows with its file locking troubles.
3664	- minitpkg shows skipped tests in report.
3665	- skip ipv6 tests on ipv4 only hosts (requires only ipv6 localhost not
3666	  ipv6 connectivity).
3667	- winsock event handler keeps track of sticky TCP events, that have
3668	  not been fully handled yet. when interest in the event(s) resumes,
3669	  they are sent again. When WOULDBLOCK is returned events are cleared.
3670	- skip tests that need signals when testing on mingw.
3671
367218 June 2008: Wouter
3673	- open testbound replay files in binary mode, because fseek/ftell
3674	  do not work in ascii-mode on windows. The b does nothing on unix.
3675	  unittest and testbound tests work on windows (xp too).
3676	- ioctlsocket prints nicer error message.
3677	- fixed up some TCP porting for winsock.
3678	- lack of IPv6 gives a warning, no fatal error.
3679	- use WSAGetLastError() on windows instead of errno for some errors.
3680
368117 June 2008: Wouter
3682	- outgoing num fds 32 by default on windows ; it supports less
3683	  fds for waiting on than unixes.
3684	- winsock_event minievent handler for windows. (you could also
3685	  attempt to link with libevent/libev ports for windows).
3686	- neater crypto check and gdi32 detection.
3687	- unbound.exe works to resolve and validate www.nlnetlabs.nl on vista.
3688
368916 June 2008: Wouter
3690	- on windows, use windows threads, mutex and thread-local-storage(Tls).
3691	- detect if openssl needs gdi32.
3692	- if no threading, THREADS_DISABLED is defined for use in the code.
3693	- sets USE_WINSOCK if using ws2_32 on windows.
3694	- wsa_strerror() function for more readable errors.
3695	- WSA Startup and Cleanup called in unbound.exe.
3696
369713 June 2008: Wouter

3706	- in iteration response type code
3707	  * first check for SOA record (negative answer) before NS record
3708	    and lameness.
3709	  * check if no AA bit for non-forwarder, and thus lame zone.

3768	  - gmtime_r is replaced by nonthreadsafe alternative if unavail.
3769	    used in rrsig time validation errors.
3770

3846	- got update for parseunbound.pl statistics script from Kai Storbeck.
3847	- tpkg tests for udp wait list.
3848	- documented 0x20 status.

3858	- fixup consistency of port_if out array during heavy use.
3859
386010 April 2008: Wouter
3861	- --with-libevent works with latest libevent 1.4.99-trunk.
3862	- added log file statistics perl script to contrib.
3863	- automatic iana ports update from makefile. 60058 available.
3864
38659 April 2008: Wouter
3866	- configure can detect libev(from its build directory) when passed
3867	  --with-libevent=/home/wouter/libev-3.2
3868	  libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
3869	- unused commpoints not listed in epoll list.
3870	- statistics-cumulative option so that the values are not reset.
3871	- config creates array of available ports, 61841 available,
3872	  it excludes <1024 and iana assigned numbers.
3873	  config statements to modify the available port numbers.
3874
38758 April 2008: Wouter
3876	- unbound tries to set the ulimit fds when started as server.
3877	  if that does not work, it will scale back its requirements.
3878
387927 March 2008: Wouter
3880	- documented /dev/random symlink from chrootdir as FAQ entry.
3881
388226 March 2008: Wouter
3883	- implemented AD bit signaling. If a query sets AD bit (but not DO)
3884	  then the AD bit is set in the reply if the answer validated.
3885	  Without including DNSSEC signatures. Useful if you have a trusted
3886	  path from the client to the resolver. Follows dnssec-updates draft.
3887
388825 March 2008: Wouter
3889	- implemented check that for NXDOMAIN and NOERROR answers a query
3890	  section must be present in the reply (by the scrubber). And it must
3891	  be equal to the question sent, at least lowercase folded.
3892	  Previously this feature happened because the cache code refused
3893	  to store such messages. However blocking by the scrubber makes
3894	  sure nothing gets into the RRset cache. Also, this looks like a
3895	  timeout (instead of an allocation failure) and this retries are
3896	  done (which is useful in a spoofing situation).
3897	- RTT banding. Band size 400 msec, this makes band around zero (fast)
3898	  include unknown servers. This makes unbound explore unknown servers.
3899
39007 March 2008: Wouter
3901	- -C config feature for harvest program.
3902	- harvest handles CNAMEs too.
3903
39045 March 2008: Wouter
3905	- patch from Hugo Koji Kobayashi for iterator logs spelling.
3906
39074 March 2008: Wouter
3908	- From report by Jinmei Tatuya, rfc2181 trust value for remainder
3909	  of a cname trust chain is lower; not full answer_AA.
3910	- test for this fix.
3911	- default config file location is /usr/local/etc/unbound.
3912	  Thus prefix is used to determine the location. This is also the
3913	  chroot and pidfile default location.
3914
39153 March 2008: Wouter
3916	- Create 0.10 svn tag.
3917	- 0.11 version in trunk.
3918	- indentation nicer.
3919
392029 February 2008: Wouter
3921	- documentation update.
3922	- fixup port to Solaris of perf test tool.
3923	- updated ldns-tarball with decl-after-statement fixes.
3924
392528 February 2008: Wouter
3926	- fixed memory leaks in libunbound (during cancellation and wait).
3927	- libunbound returns the answer packet in full.
3928	- snprintf compat update.
3929	- harvest performs lookup.
3930	- ldns-tarball update with fix for ldns_dname_label.
3931	- installs to sbin by default.
3932	- install all manual pages (unbound-host and libunbound too).
3933
393427 February 2008: Wouter
3935	- option to use caps for id randomness.
3936	- config file option use-caps-for-id: yes
3937	- harvest debug tool
3938
393926 February 2008: Wouter
3940	- delay utility delays TCP as well. If the server that is forwarded
3941	  to has a TCP error, the delay utility closes the connection.
3942	- delay does REUSE_ADDR, and can handle a server that closes its end.
3943	- answers use casing from query.
3944
394525 February 2008: Wouter
3946	- delay utility works. Gets decent thoughput too (>20000).
3947
394822 February 2008: Wouter
3949	- +2% for recursions, if identical queries (except for destination
3950	  and query ID) in the reply list, avoid re-encoding the answer.
3951	- removed TODO items for optimizations that do not show up in
3952	  profile reports.
3953	- default is now minievent - not libevent. As its faster and
3954	  not needed for regular installs, only for very large port ranges.
3955	- loop check different speedup pkt-dname-reading, 1% faster for
3956	  nocache-recursion check.
3957	- less hashing during msg parse, 4% for recursion.
3958	- small speed fix for dname_count_size_labels, +1 or +2% recursion.
3959	- some speed results noted:
3960	  optimization resulted in +40% for recursion (cache miss) and
3961	  +70 to +80 for cache hits, and +96% for version.bind.
3962	  zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
3963	  www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
3964	  www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
3965	  So, unbound can be about equal qps to NSD in cache hits.
3966	  And about 3.4x faster than BIND in cache performance.
3967	- delay utility for testing.
3968
396921 February 2008: Wouter
3970	- speedup of root-delegation message encoding by 15%.
3971	- minor speedup of compress tree_lookup, maybe 1%.
3972	- speedup of dname_lab_cmp and memlowercmp - the top functions in
3973	  profiler output, maybe a couple percent when it matters.
3974
397520 February 2008: Wouter
3976	- setup speec_cache for need-ldns-testns in dotests.
3977	- check number of queued replies on incoming queries to avoid overload
3978	  on that account.
3979	- fptr whitelist checks are not disabled in optimize mode.
3980	- do-daemonize config file option.
3981	- minievent time share initializes time at start.
3982	- updated testdata for nsec3 new algorithm numbers (6, 7).
3983	- small performance test of packet encoding (root delegation).
3984
398519 February 2008: Wouter
3986	- applied patch to unbound-host man page from Jan-Piet Mens.
3987	- fix donotquery-localhost: yes default (it erroneously was switched
3988	  to default 'no').
3989	- time is only gotten once and the value is shared across unbound.
3990	- unittest cleans up crypto, so that it has no memory leaks.
3991	- mini_event shares the time value with unbound this results in
3992	  +3% speed for cache responses and +9% for recursions.
3993	- ldns tarball update with new NSEC3 sign code numbers.
3994	- perform several reads per UDP operation. This improves performance
3995	  in DoS conditions, and costs very little in normal conditions.
3996	  improves cache response +50%, and recursions +10%.
3997	- modified asynclook test. because the callback from async is not
3998	  in any sort of lock (and thus can use all library functions freely),
3999	  this causes a tiny race condition window when the last lock is
4000	  released for a callback and a new cancel() for that callback.
4001	  The only way to remove this is by putting callbacks into some
4002	  lock window. I'd rather have the small possibility of a callback
4003	  for a cancelled function then no use of library functions in
4004	  callbacks. Could be possible to only outlaw process(), wait(),
4005	  cancel() from callbacks, by adding another lock, but I'd rather not.
4006
400718 February 2008: Wouter
4008	- patch to unbound-host from Jan-Piet Mens.
4009	- unbound host prints errors if fails to configure context.
4010	- fixup perf to resend faster, so that long waiting requests do
4011	  not hold up the queue, they become lost packets or SERVFAILs,
4012	  or can be sent a little while later (i.e. processing time may
4013	  take long, but throughput has to be high).
4014	- fixup iterator operating in no cache conditions (RD flag unset
4015	  after a CNAME).
4016	- streamlined code for RD flag setting.
4017	- profiled code and changed dname compares to be faster.
4018	  The speedup is about +3% to +8% (depending on the test).
4019	- minievent tests for eintr and eagain.
4020
402115 February 2008: Wouter
4022	- added FreeBSD rc.d script to contrib.
4023	- --prefix option for configure also changes directory: pidfile:
4024	  and chroot: defaults in config file.
4025	- added cache speed test, for cache size OK and cache too small.
4026
402714 February 2008: Wouter
4028	- start without a config file (will complain, but start with
4029	  defaults).
4030	- perf test program works.
4031
403213 February 2008: Wouter
4033	- 0.9 released.
4034	- 1.0 development. Printout ldns version on unbound -h.
4035	- start of perf tool.
4036	- bugfix to read empty lines from /etc/hosts.
4037
403812 February 2008: Wouter
4039	- fixup problem with configure calling itself if ldns-src tarball
4040	  is not present.
4041
404211 February 2008: Wouter
4043	- changed library to use ub_ instead of ub_val_ as prefix.
4044	- statistics output text nice.
4045	- etc/hosts handling.
4046	- library function to put logging to a stream.
4047	- set any option interface.
4048
40498 February 2008: Wouter
4050	- test program for multiple queries over a TCP channel.
4051	- tpkg test for stream tcp queries.
4052	- unbound replies to multiple TCP queries on a TCP channel.
4053	- fixup misclassification of root referral with NS in answer
4054	  when validating a nonrec query.
4055	- tag 0.9
4056	- layout of manpages, spelling fix in header, manpages process by
4057	  makedist, list asynclook and tcpstream tests as ldns-testns
4058	  required.
4059
40607 February 2008: Wouter
4061	- moved up all current level 2 to be level 3. And 3 to 4.
4062	  to make room for new debug level 2 for detailed information
4063	  for operators.
4064	- verbosity level 2. Describes recursion and validation.
4065	- cleaner configure script and fixes for libevent solaris.
4066	- signedness for log output memory sizes in high verbosity.
4067
40686 February 2008: Wouter
4069	- clearer explanation of threading configure options.
4070	- fixup asynclook test for nothreading (it creates only one process
4071	  to do the extended test).
4072	- changed name of ub_val_result_free to ub_val_resolve_free.
4073	- removes warning message during library linking, renamed
4074	  libunbound/unbound.c -> libunbound.c and worker to libworker.
4075	- fallback without EDNS if result is NOTIMPL as well as on FORMERR.
4076
40775 February 2008: Wouter
4078	- statistics-interval: seconds option added.
4079	- test for statistics option
4080	- ignore errors making directories, these can occur in parallel builds
4081	- fixup Makefile strip command and libunbound docs typo.
4082
408331 January 2008: Wouter
4084	- bg thread/process reads and writes the pipe nonblocking all the time
4085	  so that even if the pipe is buffered or so, the bg thread does not
4086	  block, and services both pipes and queries.
4087
408830 January 2008: Wouter
4089	- check trailing / on chrootdir in checkconf.
4090	- check if root hints and anchor files are in chrootdir.
4091	- no route to host tcp error is verbosity level 2.
4092	- removed unused send_reply_iov. and its configure check.
4093	- added prints of 'remote address is 1.2.3.4 port 53' to errors
4094	  from netevent; the basic socket errors.
4095
409628 January 2008: Wouter
4097	- fixup uninit use of buffer by libunbound (query id, flags) for
4098	  local_zone answers.
4099	- fixup uninit warning from random.c; also seems to fix sporadic
4100	  sigFPE coming out of openssl.
4101	- made openssl entropy warning more silent for library use. Needs
4102	  verbosity 1 now.
4103	- fixup forgotten locks for rbtree_searches on ctx->query tree.
4104	- random generator cleanup - RND_STATE_SIZE removed, and instead
4105	  a super-rnd can be passed at init to chain init random states.
4106	- test also does lock checks if available.
4107	- protect config access in libworker_setup().
4108	- libevent doesn't like comm_base_exit outside of runloop.
4109	- close fds after removing commpoints only (for epoll, kqueue).
4110
411125 January 2008: Wouter
4112	- added tpkg for asynclook and library use.
4113	- allows localhost to be queried when as a library.
4114	- fixup race condition between cancel and answer (in case of
4115	  really fast answers that beat the cancel).
4116	- please doxygen, put doxygen comment in one place.
4117	- asynclook -b blocking mode and test.
4118	- refactor asynclook, nicer code.
4119	- fixup race problems from opensll in rand init from library, with
4120	  a mutex around the rand init.
4121	- fix pass async_id=NULL to _async resolve().
4122	- rewrote _wait() routine, so that it is threadsafe.
4123	- cancelation is threadsafe.
4124	- asynclook extended test in tpkg.
4125	- fixed two races where forked bg process waits for (somehow shared?)
4126	  locks, so does not service the query pipe on the bg side.
4127	  Now those locks are only held for fg_threads and for bg_as_a_thread.
4128
412924 January 2008: Wouter
4130	- tested the cancel() function.
4131	- asynclook -c (cancel) feature.

4137	- new calls to set forwarding added to header and docs.
4138
413923 January 2008: Wouter
4140	- removed debug prints from if-auto, verb-algo enables some.
4141	- libunbound QUIT setup, remove memory leaks, when using threads
4142	  will share memory for passing results instead of writing it over
4143	  the pipe, only writes ID number over the pipe (towards the handler
4144	  thread that does process() ).
4145
414622 January 2008: Wouter
4147	- library code for async in libunbound/unbound.c.
4148	- fix link testbound.
4149	- fixup exit bug in mini_event.
4150	- background worker query enter and result functions.
4151	- bg query test application asynclook, it looks up multiple
4152	  hostaddresses (A records) at the same time.
4153
415421 January 2008: Wouter
4155	- libworker work, netevent raw commpoints, write_msg, serialize.
4156
415718 January 2008: Wouter
4158	- touch up of manpage for libunbound.
4159	- support for IP_RECVDSTADDR (for *BSD ip4).
4160	- fix for BSD, do not use ip4to6 mapping, make two sockets, once
4161	  ip6 and once ip4, uses socket options.
4162	- goodbye ip4to6 mapping.
4163	- update ldns-testpkts with latest version from ldns-trunk.
4164	- updated makedist for relative ldns pathnames.
4165	- library API with more information inside the result structure.
4166	- work on background resolves.
4167
416817 January 2008: Wouter
4169	- fixup configure in case -lldns is installed.
4170	- fixup a couple of doxygen warnings, about enum variables.
4171	- interface-automatic now copies the interface address from the
4172	  PKT_INFO structure as well.
4173	- manual page with library API, all on one page 'man libunbound'.
4174	- rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
4175
417616 January 2008: Wouter
4177	- incoming queries to the server with TC bit on are replied FORMERR.
4178	- interface-automatic replied the wrong source address on localhost
4179	  queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
4180	  to use ifnum=-1 to mean 'no interface, use kernel route'.
4181
418215 January 2008: Wouter
4183	- interface-automatic feature. experimental. Nice for anycast.
4184	- tpkg test for ip6 ancillary data.
4185	- removed debug prints.
4186	- porting experience, define for Solaris, test refined for BSD
4187	  compatibility. The feature probably will not work on OpenBSD.
4188	- makedist fixup for ldns-src in build-dir.
4189
419014 January 2008: Wouter
4191	- in no debug sets NDEBUG to remove asserts.
4192	- configure --enable-debug is needed for dependency generation
4193	  for assertions and for compiler warnings.
4194	- ldns.tgz updated with ldns-trunk (where buffer.h is updated).
4195	- fix lint, unit test in optimize mode.
4196	- default access control allows ::ffff:127.0.0.1 v6mapped localhost.
4197
419811 January 2008: Wouter
4199	- man page, warning removed.
4200	- added text describing the use of stub zones for private zones.
4201	- checkconf tests for bad hostnames (IP address), and for doubled
4202	  interface lines.
4203	- memory sizes can be given with 'k', 'Kb', or M or G appended.
4204
420510 January 2008: Wouter
4206	- typo in example.conf.
4207	- made using ldns-src that is included the package more portable
4208	  by linking with .lo instead of .o files in the ldns package.
4209	- nicer do-ip6: yes/no documentation.
4210	- nicer linking of libevent .o files.
4211	- man pages render correctly on solaris.
4212
42139 January 2008: Wouter
4214	- fixup openssl RAND problem, when the system is not configured to
4215	  give entropy, and the rng needs to be seeded.
4216
42178 January 2008: Wouter
4218	- print median and quartiles with extensive logging.
4219
42204 January 2008: Wouter
4221	- document misconfiguration in private network.
4222
42232 January 2008: Wouter
4224	- fixup typo in requirements.
4225	- document that 'refused' is a better choice than 'drop' for
4226	  the access control list, as refused will stop retries.
4227
42287 December 2007: Wouter
4229	- unbound-host has a -d option to show what happens. This can help
4230	  with debugging (why do I get this answer).
4231	- fixup CNAME handling, on nodata, sets and display canonname.
4232	- dot removed from CNAME display.
4233	- respect -v for NXDOMAINs.
4234	- updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
4235	- size_t to int for portability of the header file.
4236	- fixup bogus handling.
4237	- dependencies and lint for unbound-host.
4238
42396 December 2007: Wouter
4240	- library resolution works in foreground mode, unbound-host app
4241	  receives data.
4242	- unbound-host prints rdata using ldns.
4243	- unbound-host accepts trust anchors, and prints validation
4244	  information when you give -v.
4245
42465 December 2007: Wouter
4247	- locking in context_new() inside the function.
4248	- setup of libworker.
4249
42504 December 2007: Wouter
4251	- minor Makefile fixup.
4252	- moved module-stack code out of daemon/daemon into services/modstack,
4253	  preparing for code-reuse.
4254	- move context into own header file.
4255	- context query structure.
4256	- removed unused variable pwd from checkconf.
4257	- removed unused assignment from outside netw.
4258	- check timeval length of string.
4259	- fixup error in val_utils getsigner.
4260	- fixup same (*var) error in netblocktostr.
4261	- fixup memleak on parse error in localzone.
4262	- fixup memleak on packet parse error.
4263	- put ; after union in parser.y.
4264	- small hardening in iter_operate against iq==NULL.
4265	- hardening, if error reply with rcode=0 (noerror) send servfail.
4266	- fixup same (*var) error in find_rrset in msgparse, was harmless.
4267	- check return value of evtimer_add().
4268	- fixup lockorder in lruhash_reclaim(), building up a list of locked
4269	  entries one at a time. Instead they are removed and unlocked.
4270	- fptr_wlist for markdelfunc.
4271	- removed is_locked param from lruhash delkeyfunc.
4272	- moved bin_unlock during bin_split purely to please.
4273
42743 December 2007: Wouter
4275	- changed checkconf/ to smallapp/ to make room for more support tools.
4276	  (such as unbound-host).
4277	- install dirs created with -m 755 because they need to be accessible.
4278	- library extensive featurelist added to TODO.
4279	- please doxygen, lint.
4280	- library test application, with basic functionality.
4281	- fix for building in a subdirectory.
4282	- link lib fix for Leopard.
4283
428430 November 2007: Wouter
4285	- makefile that creates libunbound.la, basic file or libunbound.a
4286	  when creating static executables (no libtool).
4287	- more API setup.
4288
428929 November 2007: Wouter
4290	- 0.9 public API start.
4291
429228 November 2007: Wouter
4293	- Changeup plan for 0.8 - no complication needed, a simple solution
4294	  has been chosen for authoritative features.
4295	- you can use single quotes in the config file, so it is possible
4296	  to specify TXT records in local data.
4297	- fixup small memory problem in implicit transparent zone creation.
4298	- test for implicit zone creation and multiple RR RRsets local data.
4299	- local-zone nodefault test.
4300	- show testbound testlist on commit.
4301	- iterator normalizer changes CNAME chains ending in NXDOMAIN where
4302	  the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
4303	  domain exists).
4304	- nicer verbosity: 0 and 1 levels.
4305	- lower nonRDquery chance of eliciting wrongly typed validation
4306	  requiring message from the cache.
4307	- fix for nonRDquery validation typing; nodata is detected when
4308	  SOA record in auth section (all validation-requiring nodata messages
4309	  have a SOA record in authority, so this is OK for the validator),
4310	  and NS record is needed to be a referral.
4311	- duplicate checking when adding NSECs for a CNAME, and test.
4312	- created svn tag 0.8, after completing testbed tests.
4313
431427 November 2007: Wouter
4315	- per suggestion in rfc2308, replaced default max-ttl value with 1 day.
4316	- set size of msgparse lookup table to 32, from 1024, so that its size
4317	  is below the 2048 regional large size threshold, and does not cause
4318	  a call to malloc when a message is parsed.
4319	- update of memstats tool to print number of allocation calls.
4320	  This is what is taking time (not space) and indicates the avg size
4321	  of the allocations as well. region_alloc stat is removed.
4322
432322 November 2007: Wouter
4324	- noted EDNS in-the-middle dropping trouble as a TODO.
4325	  At this point theoretical, no user trouble has been reported.
4326	- added all default AS112 zones.
4327	- answers from local zone content.
4328		* positive answer, the rrset in question
4329		* nodata answer (exist, but not that type).
4330		* nxdomain answer (domain does not exist).
4331		* empty-nonterminal answer.
4332		* But not: wildcard, nsec, referral, rrsig, cname/dname,
4333			or additional section processing, NS put in auth.
4334	- test for correct working of static and transparent and couple
4335	  of important defaults (localhost, as112, reverses).
4336	  Also checks deny and refuse settings.
4337	- fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
4338
433921 November 2007: Wouter
4340	- local zone internal data setup.
4341
434220 November 2007: Wouter
4343	- 0.8 - str2list config support for double string config options.
4344	- local-zone and local-data options, config storage and documentation.
4345
434619 November 2007: Wouter
4347	- do not downcase NSEC and RRSIG for verification. Follows
4348	  draft-ietf-dnsext-dnssec-bis-updates-06.txt.
4349	- fixup leaking unbound daemons at end of tests.
4350	- README file updated.
4351	- nice libevent not found error.
4352	- README talks about gnu make.
4353	- 0.8: unit test for addr_mask and fixups for it.
4354	  and unit test for addr_in_common().
4355	- 0.8: access-control config file element.
4356	  and unit test rpl replay file.
4357	- 0.8: fixup address reporting from netevent.
4358
435916 November 2007: Wouter
4360	- privilege separation is not needed in unbound at this time.
4361	  TODO item marked as such.
4362	- created beta-0.7 branch for support.
4363	- tagged 0.7 for beta release.
4364	- moved trunk to 0.8 for 0.8(auth features) development.
4365	- 0.8: access control list setup.
4366
436715 November 2007: Wouter
4368	- review fixups from Jelte.
4369
437014 November 2007: Wouter
4371	- testbed script does not recreate configure, since its in svn now.
4372	- fixup checkconf test so that it does not test
4373	  /etc/unbound/unbound.conf.
4374	- tag 0.6.
4375
437613 November 2007: Wouter
4377	- remove debug print.
4378	- fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
4379
438012 November 2007: Wouter
4381	- fixup signal handling where SIGTERM could be ignored if a SIGHUP
4382	  arrives later on.
4383	- bugreports to unbound-bugs@nlnetlabs.nl
4384	- fixup testbound so it exits cleanly.
4385	- cleanup the caches on a reload, so that rrsetID numbers won't clash.
4386
43879 November 2007: Wouter
4388	- took ldns snapshot in repo.
4389	- default config file is /etc/unbound/unbound.conf.
4390	  If it doesn't exist, it is installed with the doc/example.conf file.
4391	  The file is not deleted on uninstall.
4392	- default listening is not all, but localhost interfaces.
4393
43948 November 2007: Wouter
4395	- Fixup chroot and drop user privileges.
4396	- new L root ip address in default hints.
4397
43981 November 2007: Wouter
4399	- Fixup of crash on reload, due to anchors in env not NULLed after
4400	  dealloc during deinit.
4401	- Fixup of chroot call. Happens after privileges are dropped, so
4402	  that checking the passwd entry still works.
4403	- minor touch up of clear() hashtable function.
4404	- VERB_DETAIL prints out what chdir, username, chroot is being done.
4405	- when id numbers run out, caches are cleared, as in design notes.
4406	  Tested with a mock setup with very few bits in id, it worked.
4407	- harden-dnssec-stripped: yes is now default. It insists on dnssec
4408	  data for trust anchors. Included tests for the feature.
4409
441031 October 2007: Wouter
4411	- cache-max-ttl config option.
4412	- building outside sourcedir works again.
4413	- defaults more secure:
4414		username: "unbound"
4415		chroot: "/etc/unbound"
4416	  The operator can override them to be less secure ("") if necessary.
4417	- fix horrible oversight in sorting rrset references in a message,
4418	  sort per reference key pointer, not on referencepointer itself.
4419	- pidfile: "/etc/unbound/unbound.pid" is now the default.
4420	- tests changed to reflect the updated default.
4421	- created hashtable clear() function that respects locks.
4422
442330 October 2007: Wouter
4424	- fixup assertion failure that relied on compressed names to be
4425	  smaller than uncompressed names. A packet from comrite.com was seen
4426	  to be compressed to a larger size. Added it as unit test.
4427	- quieter logging at low verbosity level for common tcp messages.
4428	- no greedy TTL update.
4429
443023 October 2007: Wouter
4431	- fixup (grand-)parent problem for dnssec-lameness detection.
4432	- fixup tests to do additional section processing for lame replies,
4433	  since the detection needs that.
4434	- no longer trust in query section in reply during dnssec lame detect.
4435	- dnssec lameness does not make the server never ever queried, but
4436	  non-preferred. If no other servers exist or answer, the dnssec lame
4437	  server is used; the fastest dnssec lame server is chosen.
4438	- added test then when trust anchor cannot be primed (nodata), the
4439	  insecure mode from unbound works.
4440	- Fixup max queries per thread, any more are dropped.
4441
444222 October 2007: Wouter
4443	- added donotquerylocalhost config option. Can be turned off for
4444	  out test cases.
4445	- ISO C compat changes.
4446	- detect RA-no-AA lameness, as LAME.
4447	- DNSSEC-lameness detection, as LAME.
4448	  See notes in requirements.txt for choices made.
4449	- tests for lameness detection.
4450	- added all to make test target; need unbound for fwd tests.
4451	- testbound does not pollute /etc/unbound.
4452
445319 October 2007: Wouter
4454	- added configure (and its files) to svn, so that the trunk is easier
4455	  to use. ./configure, config.guess, config.sub, ltmain.sh,
4456	  and config.h.in.
4457	- added yacc/lex generated files, util/configlexer.c,
4458	  util/configparser.c util/configparser.h, to svn.
4459	- without lex no attempt to use it.
4460	- unsecure response validation collated into one block.
4461	- remove warning about const cast of cfgfile name.
4462	- outgoing-interfaces can be different from service interfaces.
4463	- ldns-src configure is done during unbound configure and
4464	  ldns-src make is done during unbound make, and so inherits the
4465	  make arguments from the unbound make invocation.
4466	- nicer error when libevent problem causes instant exit on signal.
4467	- read root hints from a root hint file (like BIND does).
4468
446918 October 2007: Wouter
4470	- addresses are logged with errors.
4471	- fixup testcode fake event to remove pending before callback
4472	  since the callback may create new pending items.
4473	- tests updated because retries are now in iterator module.
4474	- ldns-testpkts code is checked for differences between unbound
4475	  and ldns by makedist.sh.
4476	- ldns trunk from today added in svn repo for fallback in case
4477	  no ldns is installed on the system.
4478	  make download_ldns refreshes the tarball with ldns svn trunk.
4479	- ldns-src.tar.gz is used if no ldns is found on the system, and
4480	  statically linked into unbound.
4481	- start of regional allocator code.
4482	- regional uses less memory and variables, simplified code.
4483	- remove of region-allocator.
4484	- alloc cache keeps a cache of recently released regional blocks,
4485	  up to a maximum.
4486	- make unit test cleanly free memory.
4487
448817 October 2007: Wouter
4489	- fixup another cycle detect and ns-addr timeout resolution bug.
4490	  This time by refusing delegations from the cache without addresses
4491	  when resolving a mandatory-glue nameserver-address for that zone.
4492	  We're going to have to ask a TLD server anyway; might as well be
4493	  the TLD server for this name. And this resolves a lot of cases where
4494	  the other nameserver names lead to cycles or are not available.
4495	- changed random generator from random(3) clone to arc4random wrapped
4496	  for thread safety. The random generator is initialised with
4497	  entropy from the system.
4498	- fix crash where failure to prime DNSKEY tried to print null pointer
4499	  in the log message.
4500	- removed some debug prints, only verb_algo (4) enables them.
4501	- fixup test; new random generator took new paths; such as one
4502	  where no scripted answer was available.
4503	- mark insecure RRs as insecure.
4504	- fixup removal of nonsecure items from the additional.
4505	- reduced timeout values to more realistic, 376 msec (262 msec has
4506	  90% of roundtrip times, 512 msec has 99% of roundtrip times.)
4507	- server selection failover to next server after timeout (376 msec).
4508
450916 October 2007: Wouter
4510	- no malloc in log_hex.
4511	- assertions around system calls.
4512	- protect against gethostname without ending zero.
4513	- ntop output is null terminated by unbound.
4514	- pidfile content null termination
4515	- various snprintf use sizeof(stringbuf) instead of fixed constant.
4516	- changed loopdetect % 8 with & 0x7 since % can become negative for
4517	  weird negative input and particular interpretation of integer math.
4518	- dname_pkt_copy checks length of result, to protect result buffers.
4519	  prints an error, this should not happen. Bad strings should have
4520	  been rejected earlier in the program.
4521	- remove a size_t underflow from msgreply size func.
4522
452315 October 2007: Wouter
4524	- nicer warning.
4525	- fix IP6 TCP, wrong definition check. With test package.
4526	- fixup the fact that the query section was not compressed to,
4527	  the code was there but was called by value instead of by reference.
4528	  And test for the case, uses xxd and nc.
4529	- more portable ip6 check for sockaddr types.
4530
45318 October 2007: Wouter
4532	- --disable-rpath option in configure for 64bit systems with
4533	  several dynamic lib dirs.
4534
45357 October 2007: Wouter
4536	- fixup tests for no AD bit in non-DO queries.
4537	- test that makes sure AD bit is not set on non-DO query.
4538
45396 October 2007: Wouter
4540	- removed logfile open early. It did not have the proper permissions;
4541	  it was opened as root instead of the user. And we cannot change user
4542	  id yet, since chroot and bind ports need to be done.
4543	- callback checks for event callbacks done from mini_event. Because
4544	  of deletions cannot do this from netevent. This means when using
4545	  libevent the protection does not work on event-callbacks.
4546	- fixup too small reply (did not zero counts).
4547	- fixup reply no longer AD bit when query without DO bit.
4548
45495 October 2007: Wouter
4550	- function pointer whitelist.
4551
45524 October 2007: Wouter
4553	- overwrite sensitive random seed value after use.
4554	- switch to logfile very soon if not -d (console attached).
4555	- error messages do not reveal the trustanchor contents.
4556	- start work on function pointer whitelists.
4557
45583 October 2007: Wouter
4559	- fix for multiple empty nonterminals, after multiple DSes in the
4560	  chain of trust.
4561	- mesh checks if modules are looping, and stops them.
4562	- refetch with CNAMEd nameserver address regression test added.
4563	- fixup line count bug in testcode, so testbound prints correct line
4564	  number with parse errors.
4565	- unit test for multiple ENT case.
4566	- fix for cname out of validated unsec zone.
4567	- fixup nasty id=0 reuse. Also added assertions to detect its
4568	  return (the assertion catches in the existing test cases).
4569
45701 October 2007: Wouter
4571	- skip F77, CXX, objC tests in configure step.
4572	- fixup crash in refetch glue after a CNAME.
4573	  and protection against similar failures (with error print).
4574
457528 September 2007: Wouter
4576	- test case for unbound-checkconf, fixed so it also checks the
4577	  interface: statements.
4578
457926 September 2007: Wouter
4580	- SIGHUP will reopen the log file.
4581	- Option to log to syslog.
4582	- please lint, fixup tests (that went to syslog on open, oops).
4583	- config check program.
4584
458525 September 2007: Wouter
4586	- tests for NSEC3. Fixup bitmap checks for NSEC3.
4587	- positive ANY response needs to check if wildcard expansion, and
4588	  check that original data did not exist.
4589	- tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
4590	  delegation, for abuse of child zone apex nsec3.
4591	- create 0.5 release tag.
4592
459324 September 2007: Wouter
4594	- do not make test programs by default.
4595	- But 'make test' will perform all of the tests.
4596	- Advertise builtin select libevent alternative when no libevent
4597	  is found.
4598	- signit can generate NSEC3 hashes, for generating tests.
4599	- multiple nsec3 paramaters in message test.
4600	- too high nsec3 iterations becomes insecure test.
4601
460221 September 2007: Wouter
4603	- fixup empty_DS_name allocated in wrong region (port DEC Alpha).
4604	- fixup testcode lock safety (port FreeBSD).
4605	- removes subscript has type char warnings (port Solaris 9).
4606	- fixup of field with format type to int (port MacOS/X intel).
4607	- added test for infinite loop case in nonRD answer validation.
4608	  It was a more general problem, but hard to reproduce. When an
4609	  unsigned rrset is being validated and the key fetched, the DS
4610	  sequence is followed, but if the final name has no DS, then no
4611	  proof is possible - the signature has been stripped off.
4612
461320 September 2007: Wouter
4614	- fixup and test for NSEC wildcard with empty nonterminals.
4615	- makedist.sh fixup for svn info.
4616	- acl features request in plan.
4617	- improved DS empty nonterminal handling.
4618	- compat with ANS nxdomain for empty nonterminals. Attempts the nodata
4619	  proof anyway, which succeeds in ANS failure case.
4620	- striplab protection in case it becomes -1.
4621	- plans for static and blacklist config.
4622
462319 September 2007: Wouter
4624	- comments about non-packed usage.
4625	- plan for overload support in 0.6.
4626	- added testbound tests for a failed resolution from the logs
4627	  and for failed prime when missing glue.
4628	- fixup so useless delegation points are not returned from the
4629	  cache. Also the safety belt is used if priming fails to complete.
4630	- fixup NSEC rdata not to be lowercased, bind compat.
4631
463218 September 2007: Wouter
4633	- wildcard nsec3 testcases, and fixup to get correct wildcard name.
4634	- validator prints subtype classification for debug.
4635
463617 September 2007: Wouter
4637	- NSEC3 hash cache unit test.
4638	- validator nsec3 nameerror test.
4639
464014 September 2007: Wouter
4641	- nsec3 nodata proof, nods proof, wildcard proof.
4642	- nsec3 support for cname chain ending in noerror or nodata.
4643	- validator calls nsec3 proof routines if no NSECs prove anything.
4644	- fixup iterator bug where it stored the answer to a cname under
4645	  the wrong qname into the cache. When prepending the cnames, the
4646	  qname has to be reset to the original qname.
4647
464813 September 2007: Wouter
4649	- nsec3 find matching and covering, ce proof, prove namerror msg.
4650
465112 September 2007: Wouter
4652	- fixup of manual page warnings, like for NSD bugreport.
4653	- nsec3 work, config, max iterations, filter, and hash cache.
4654
46556 September 2007: Wouter
4656	- fixup to find libevent on mac port install.
4657	- fixup size_t vs unsigned portability in validator/sigcrypt.
4658	- please compiler on different platforms, for unreachable code.
4659	- val_nsec3 file.
4660	- pthread_rwlock type is optional, in case of old pthread libs.
4661
46625 September 2007: Wouter
4663	- cname, name error validator tests.
4664	- logging of qtype ANY works.
4665	- ANY type answers get RRSIG in answer section of replies (but not
4666	  in other sections, unless DO bit is on).
4667	- testbound can replay a TCP query (set MATCH TCP in the QUERY).
4668	- DS and noDS referral validation test.
4669	- if you configure many trust anchors, parent trust anchors can
4670	  securely deny existance of child trust anchors, if validated.
4671	- not all *.name NSECs are present because a wildcard was matched,
4672	  and *.name NSECs can prove nodata for empty nonterminals.
4673	  Also, for wildcard name NSECs, check they are not from the parent
4674	  zone (for wildcarded zone cuts), and check absence of CNAME bit,
4675	  for a nodata proof.
4676	- configure option for memory allocation debugging.
4677	- port configure option for memory allocation to solaris10.
4678
46794 September 2007: Wouter
4680	- fixup of Leakage warning when serviced queries processed multiple
4681	  callbacks for the same query from the same server.
4682	- testbound removes config file from /tmp on failed exit.
4683	- fixup for referral cleanup of the additional section.
4684	- tests for cname, referral validation.
4685	- neater testbound tpkg output.
4686	- DNAMEs no longer match their apex when synthesized from the cache.
4687	- find correct signer name for DNAME responses.
4688	- wildcarded DNAME test and fixup code to detect.
4689	- prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
4690	  So that wildcarded CNAMEs get their NSEC with them to the answer.
4691	- test for a CNAME to a DNAME to a CNAME to an answer, all from
4692	  different domains, for key fetching and signature checking of
4693	  CNAME'd messages.
4694
46953 September 2007: Wouter
4696	- Fixed error in iterator that would cause assertion failure in
4697	  validator. CNAME to a NXDOMAIN response was collated into a response
4698	  with both a CNAME and the NXDOMAIN rcode. Added a test that the
4699	  rcode is changed to NOERROR (because of the CNAME).
4700	- timeout on tcp does not lead to spurious leakage detect.
4701	- account memory for name of lame zones, so that memory leakages does
4702	  not show lame cache growth as a leakage growth.
4703	- config setting for lameness cache expressed in bytes, instead of
4704	  number of entries.
4705	- tool too summarize allocations per code line.
4706
470731 August 2007: Wouter
4708	- can read bind trusted-keys { ... }; files, in a compatibility mode.
4709	- iterator should not detach target queries that it still could need.
4710	  the protection against multiple outstanding queries is moved to a
4711	  current_query num check.
4712	- validator nodata, positive, referral tests.
4713	- dname print can print '*' wildcard.
4714
471530 August 2007: Wouter
4716	- fixup override date config option.
4717	- config options to control memory usage.
4718	- caught bad free of un-alloced data in worker_send error case.
4719	- memory accounting for key cache (trust anchors and temporary cache).
4720	- memory accounting fixup for outside network tcp pending waits.
4721	- memory accounting fixup for outside network tcp callbacks.
4722	- memory accounting for iterator fixed storage.
4723	- key cache size and slabs config options.
4724	- lib crypto cleanups at exit.
4725
472629 August 2007: Wouter
4727	- test tool to sign rrsets for testing validator with.
4728	- added RSA and DSA test keys, public and private pairs, 512 bits.
4729	- default configuration is with validation enabled.
4730	  Only a trust-anchor needs to be configured for DNSSEC to work.
4731	- do not convert to DER for DSA signature verification.
4732	- validator replay test file, for a DS to DNSKEY DSA key prime and
4733	  positive response.
4734
473528 August 2007: Wouter
4736	- removed double use for udp buffers, that could fail,
4737	  instead performs a malloc to do the backup.
4738	- validator validates referral messages, by validating all the rrsets
4739	  and stores the rrsets in the cache. Further referral (nonRD queries)
4740	  replies are made from the rrset cache directly. Unless unchecked
4741	  rrsets are encountered, there are then validated.
4742	- enforce that signing is done by a parent domain (or same domain).
4743	- adjust TTL downwards if rrset TTL bigger than signature allows.
4744	- permissive mode feature, sets AD bit for secure, but bogus does
4745	  not give servfail (bogus is changed into indeterminate).
4746	- optimization of rrset verification. rr canonical sorting is reused,
4747	  for the same rrset. canonical rrset image in buffer is reused for
4748	  the same signature.
4749	- if the rrset is too big (64k exactly + large owner name) the
4750	  canonicalization routine will fail if it does not fit in buffer.
4751	- faster verification for large sigsets.
4752	- verb_detail mode reports validation failures, but not the entire
4753	  algorithm for validation. Key prime failures are reported as
4754	  verb_ops level.
4755
475627 August 2007: Wouter
4757	- do not garble the edns if a cache answer fails.
4758	- answer norecursive from cache if possible.
4759	- honor clean_additional setting when returning secure non-recursive
4760	  referrals.
4761	- do not store referral in msg cache for nonRD queries.
4762	- store verification status in the rrset cache to speed up future
4763	  verification.
4764	- mark rrsets indeterminate and insecure if they are found to be so.
4765	  and store this in the cache.
4766
476724 August 2007: Wouter
4768	- message is bogus if unsecure authority rrsets are present.
4769	- val-clean-additional option, so you can turn it off.
4770	- move rrset verification out of the specific proof types into one
4771	  routine. This makes the proof routines prettier.
4772	- fixup cname handling in validator, cname-to-positive and cname-to-
4773	  nodata work.
4774	- Do not synthesize DNSKEY and DS responses from the rrset cache if
4775	  the rrset is from the additional section. Signatures may have
4776	  fallen off the packet, and cause validation failure.
4777	- more verbose signature date errors (with the date attached).
4778	- increased default infrastructure cache size. It is important for
4779	  performance, and 1000 entries are only 212k (or a 400 k total cache
4780	  size). To 10000 entries (for 2M entries, 4M cache size).
4781
478223 August 2007: Wouter
4783	- CNAME handling - move needs_validation to before val_new().
4784	  val_new() setups the chase-reply to be an edited copy of the msg.
4785	  new classification, and find signer can find for it.
4786	  removal of unsigned crap from additional, and query restart for
4787	  cname.
4788	- refuse to follow wildcarded DNAMEs when validating.
4789	  But you can query for qtype ANY, or qtype DNAME and validate that.
4790
479122 August 2007: Wouter
4792	- bogus TTL.
4793	- review - use val_error().
4794
479521 August 2007: Wouter
4796	- ANY response validation.
4797	- store security status in cache.
4798	- check cache security status and either send the query to be
4799	  validated, return the query to client, or send servfail to client.
4800	  Sets AD bit on validated replies.
4801	- do not examine security status on an error reply in mesh_done.
4802	- construct DS, DNSKEY messages from rrset cache.
4803	- manual page entry for override-date.
4804
480520 August 2007: Wouter
4806	- validate and positive validation, positive wildcard NSEC validation.
4807	- nodata validation, nxdomain validation.
4808
480918 August 2007: Wouter
4810	- process DNSKEY response in FINDKEY state.
4811
481217 August 2007: Wouter
4813	- work on DS2KE routine.
4814	- val_nsec.c for validator NSEC proofs.
4815	- unit test for NSEC bitmap reading.
4816	- dname iswild and canonical_compare with unit tests.
4817
481816 August 2007: Wouter
4819	- DS sig unit test.
4820	- latest release libevent 1.3c and 1.3d have threading fixed.
4821	- key entry fixup data pointer and ttl absolute.
4822	- This makes a key-prime succeed in validator, with DS or DNSKEY as
4823	  trust-anchor.
4824	- fixup canonical compare byfield routine, fix bug and also neater.
4825	- fixed iterator response type classification for queries of type
4826	  ANY and NS.
4827	  dig ANY gives sometimes NS rrset in AN and NS section, and parser
4828	  removes the NS section duplicate. dig NS gives sometimes the NS
4829	  in the answer section, as referral.
4830	- validator FINDKEY state.
4831
483215 August 2007: Wouter
4833	- crypto calls to verify signatures.
4834	- unit test for rrsig verification.
4835
483614 August 2007: Wouter
4837	- default outgoing ports changed to avoid port 2049 by default.
4838	  This port is widely blocked by firewalls.
4839	- count infra lameness cache in memory size.
4840	- accounting of memory improved
4841	- outbound entries are allocated in the query region they are for.
4842	- extensive debugging for memory allocations.
4843	- --enable-lock-checks can be used to enable lock checking.
4844	- protect undefs in config.h from autoheaders ministrations.
4845	- print all received udp packets. log hex will print on multiple
4846	  lines if needed.
4847	- fixed error in parser with backwards rrsig references.
4848	- mark cycle targets for iterator did not have CD flag so failed
4849	  its task.
4850
485113 August 2007: Wouter
4852	- fixup makefile, if lexer is missing give nice error and do not
4853	  mess up the dependencies.
4854	- canonical compare routine updated.
4855	- canonical hinfo compare.
4856	- printout list of the queries that the mesh is working on.
4857
485810 August 2007: Wouter
4859	- malloc and free overrides that track total allocation and frees.
4860	  for memory debugging.
4861	- work on canonical sort.
4862
48639 August 2007: Wouter
4864	- canonicalization, signature checks
4865	- dname signature label count and unit test.
4866	- added debug heap size print to memory printout.
4867	- typo fixup in worker.c
4868	- -R needed on solaris.
4869	- validator override option for date check testing.
4870
48718 August 2007: Wouter
4872	- ldns _raw routines created (in ldns trunk).
4873	- sigcrypt DS digest routines
4874	- val_utils uses sigcrypt to perform signature cryptography.
4875	- sigcrypt keyset processing
4876
48777 August 2007: Wouter
4878	- security status type.
4879	- security status is copied when rdata is equal for rrsets.
4880	- rrset id is updated to invalidate all the message cache entries
4881	  that refer to NSEC, NSEC3, DNAME rrsets that have changed.
4882	- val_util work
4883	- val_sigcrypt file for validator signature checks.
4884
48856 August 2007: Wouter
4886	- key cache for validator.
4887	- moved isroot and dellabel to own dname routines, with unit test.
4888
48893 August 2007: Wouter
4890	- replanning.
4891	- scrubber check section of lame NS set.
4892	- trust anchors can be in config file or read from zone file,
4893	  DS and DNSKEY entries.
4894	- unit test trust anchor storage.
4895	- trust anchors converted to packed rrsets.
4896	- key entry definition.
4897
48982 August 2007: Wouter
4899	- configure change for latest libevent trunk version (needs -lrt).
4900	- query_done and walk_supers are moved out of module interface.
4901	- fixup delegation point duplicates.
4902	- fixup iterator scrubber; lame NS set is let through the scrubber
4903	  so that the classification is lame.
4904	- validator module exists, and does nothing but pass through,
4905	  with calling of next module and return.
4906	- validator work.
4907
49081 August 2007: Wouter
4909	- set version to 0.5
4910	- module work for module to module interconnections.
4911	- config of modules.
4912	- detect cycle takes flags.
4913
491431 July 2007: Wouter
4915	- updated plan
4916	- release 0.4 tag.
4917
491830 July 2007: Wouter
4919	- changed random state init, so that sequential process IDs are not
4920	  cancelled out by sequential thread-ids in the random number seed.
4921	- the fwd_three test, which sends three queries to unbound, and
4922	  unbound is kept waiting by ldns-testns for 3 seconds, failed
4923	  because the retry timeout for default by unbound is 3 seconds too,
4924	  it would hit that timeout and fail the test. Changed so that unbound
4925	  is kept waiting for 2 seconds instead.
4926
492727 July 2007: Wouter
4928	- removed useless -C debug option. It did not work.
4929	- text edit of documentation.
4930	- added doc/CREDITS file, referred to by the manpages.
4931	- updated planning.
4932
493326 July 2007: Wouter
4934	- cycle detection, for query state dependencies. Will attempt to
4935	  circumvent the cycle, but if no other targets available fails.
4936	- unit test for AXFR, IXFR response.
4937	- test for cycle detection.
4938
493925 July 2007: Wouter
4940	- testbound read ADDRESS and check it.
4941	- test for version.bind and friends.
4942	- test for iterator chaining through several referrals.
4943	- test and fixup for refetch for glue. Refetch fails if glue
4944	  is still not provided.
4945
494624 July 2007: Wouter
4947	- Example section in config manual.
4948	- Addr stored for range and moment in replay.
4949
495020 July 2007: Wouter
4951	- Check CNAME chain before returning cache entry with CNAMEs.
4952	- Option harden-glue, default is on. It will discard out of zone
4953	  data. If disabled, performance is faster, but spoofing attempts
4954	  become a possibility. Note that still normalize scrubbing is done,
4955	  and that the potentially spoofed data is used for infrastructure
4956	  and not returned to the client.
4957	- if glue times out, refetch by asking parent of delegation again.
4958	  Much like asking for DS at the parent side.
4959	- TODO items from forgery-resilience draft.
4960	  and on memory handling improvements.
4961	- renamed module_event_timeout to module_event_noreply.
4962	- memory reporting code; reports on memory usage after handling
4963	  a network packet (not on cache replies).
4964
496519 July 2007: Wouter
4966	- shuffle NS selection when getting nameserver target addresses.
4967	- fixup of deadlock warnings, yield cpu in checklock code so that
4968	  freebsd scheduler selects correct process to run.
4969	- added identity and version config options and replies.
4970	- store cname messages complete answers.
4971
497218 July 2007: Wouter
4973	- do not query addresses, 127.0.0.1, and ::1 by default.
4974
497517 July 2007: Wouter
4976	- forward zone options in config file.
4977	- forward per zone in iterator. takes precendence over stubs.
4978	- fixup commithooks.
4979	- removed forward-to and forward-to-port features, subsumed by
4980	  new forward zones.
4981	- fix parser to handle absent server: clause.
4982	- change untrusted rrset test to account for scrubber that is now
4983	  applied during the test (which removes the poison, by the way).
4984	- feature, addresses can be specified with @portnumber, like nsd.conf.
4985	- test config files changed over to new forwarder syntax.
4986
498727 June 2007: Wouter
4988	- delete of mesh does a postorder traverse of the tree.
4989	- found and fixed a memory leak. For TTL=0 messages, that would
4990	  not be cached, instead the msg-replyinfo structure was leaked.
4991	- changed server selection so it will filter out hosts that are
4992	  unresponsive. This is defined as a host with the maximum rto value.
4993	  This means that unbound tried the host for retries up to 120 secs.
4994	  The rto value will time out after host-ttl seconds from the cache.
4995	  This keeps such unresolvable queries from taking up resources.
4996	- utility for keeping histogram.
4997
499826 June 2007: Wouter
4999	- mesh is called by worker, and iterator uses it.
5000	  This removes the hierarchical code.
5001	  QueryTargets state and Finished state are merged for iterator.
5002	- forwarder mode no longer sets AA bit on first reply.
5003	- rcode in walk_supers is not needed.
5004
500525 June 2007: Wouter
5006	- more mesh work.
5007	- error encode routine for ease.
5008
500922 June 2007: Wouter
5010	- removed unused _node iterator value from rbtree_t. Takes up space.
5011	- iterator can handle querytargets state without a delegation point
5012	  set, so that a priming(stub) subquery error can be handled.
5013	- iterator stores if it is priming or not.
5014	- log_query_info() neater logging.
5015	- changed iterator so that it does not alter module_qstate.qinfo
5016	  but keeps a chase query info. Also query_flags are not altered,
5017	  the iterator uses chase_flags.
5018	- fixup crash in case no ports for the family exist.
5019
502021 June 2007: Wouter
5021	- Fixup secondary buffer in case of error callback.
5022	- cleanup slumber list of runnable states.
5023	- module_subreq_depth fails to work in slumber list.
5024	- fixup query release for cached results to sub targets.
5025	- neater error for tcp connection failure, shows addr in verbose.
5026	- rbtree_init so that it can be used with preallocated memory.
5027
502820 June 2007: Wouter
5029	- new -C option to enable coredumps after forking away.
5030	- doc update.
5031	- fixup CNAME generation by scrubber, and memory allocation of it.
5032	- fixup deletion of serviced queries when all callbacks delete too.
5033	- set num target queries to 0 when you move them to slumber list.
5034	- typo in check caused subquery errors to be ignored, fixed.
5035	- make lint happy about rlim_t.
5036	- freeup of modules after freeup of module-states.
5037	- duplicate replies work, this uses secondary udp buffer in outnet.
5038
503919 June 2007: Wouter
5040	- nicer layout in stats.c, review 0.3 change.
5041	- spelling improvement, review 0.3 change.
5042	- uncapped timeout for server selection, so that very fast or slow
5043	  servers will stand out from the rest.
5044	- target-fetch-policy: "3 2 1 0 0" config setting.
5045	- fixup queries answered without RD bit (for root prime results).
5046	- refuse AXFR and IXFR requests.
5047	- fixup RD flag in error reply from iterator. fixup RA flag from
5048	  worker error reply.
5049	- fixup encoding of very short edns buffer sizes, now sets TC bit.
5050	- config options harden-short-bufsize and harden-large-queries.
5051
505218 June 2007: Wouter
5053	- same, move subqueries to slumber list when first has resolved.
5054	- fixup last fix for duplicate callbacks.
5055	- another offbyone in targetcounter. Also in Java prototype by the way.
5056
505715 June 2007: Wouter
5058	- if a query asks to be notified of the same serviced query result
5059	  multiple times, this will succeed. Only one callback will happen;
5060	  multiple outbound-list entries result (but the double cleanup of it
5061	  will not matter).
5062	- when iterator moves on due to CNAME or referral, it will remove
5063	  the subqueries (for other targets). These are put on the slumber
5064	  list.
5065	- state module wait subq is OK with no new subqs, an old one may have
5066	  stopped, with an error, and it is still waiting for other ones.
5067	- if a query loops, halt entire query (easy way to clean up properly).
5068
506914 June 2007: Wouter
5070	- num query targets was > 0 , not >= 0 compared, so that fetch
5071	  policy of 0 did nothing.
5072
507313 June 2007: Wouter
5074	- debug option: configure --enable-static-exe for compile where
5075	  ldns and libevent are linked statically. Default is off.
5076	- make install and make uninstall. Works with static-exe and without.
5077	  installation of unbound binary and manual pages.
5078	- alignement problem fix on solaris 64.
5079	- fixup address in case of TCP error.
5080
508112 June 2007: Wouter
5082	- num target queries was set to 0 at a bad time. Default it to 0 and
5083	  increase as target queries are done.
5084	- synthesize CNAME and DNAME responses from the cache.
5085	- Updated doxygen config for doxygen 1.5.
5086	- aclocal newer version.
5087	- doxygen 1.5 fixes for comments (for the strict check on docs).
5088
508911 June 2007: Wouter
5090	- replies on TCP queries have the address field set in replyinfo,
5091	  for serviced queries, because the initiator does not know that
5092	  a TCP fallback has occured.
5093	- omit DNSSEC types from nonDO replies, except if qtype is ANY or
5094	  if qtype directly queries for the type (and then only show that
5095	  'unknown type' in the answer section).
5096	- fixed message parsing where rrsigs on their own would be put
5097	  in the signature list over the rrsig type.
5098
50997 June 2007: Wouter
5100	- fixup error in double linked list insertion for subqueries and
5101	  for outbound list of serviced queries for iterator module.
5102	- nicer printout of outgoing port selection.
5103	- fixup cname target readout.
5104	- nicer debug output.
5105	- fixup rrset counts when prepending CNAMEs to the answer.
5106	- fixup rrset TTL for prepended CNAMEs.
5107	- process better check for looping modules, and which submodule to
5108	  run next.
5109	- subreq insertion code fixup for slumber list.
5110	- VERB_DETAIL, verbosity: 2 level gives short but readable output.
5111	  VERB_ALGO, verbosity: 3 gives extensive output.
5112	- fixup RA bit in cached replies.
5113	- fixup CNAME responses from the cache no longer partial response.
5114	- error in network send handled without leakage.
5115	- enable ip6 from config, and try ip6 addresses if available,
5116	  if ip6 is not connected, skips to next server.
5117
51185 June 2007: Wouter
5119	- iterator state finished.
5120	- subrequests without parent store in cache and stop.
5121	- worker slumber list for ongoing promiscuous queries.
5122	- subrequest error handling.
5123	- priming failure returns SERVFAIL.
5124	- priming gives LAME result, returns SERVFAIL.
5125	- debug routine to print dns_msg as handled by iterator.
5126	- memleak in config file stubs fixup.
5127	- more small bugs, in scrubber, query compare no ID for lookup,
5128	  in dname validation for NS targets.
5129	- sets entry.key for new special allocs.
5130	- lognametypeclass can display unknown types and classes.
5131
51324 June 2007: Wouter
5133	- random selection of equally preferred nameserver targets.
5134	- reply info copy routine. Reuses existing code.
5135	- cache lameness in response handling.
5136	- do not touch qstate after worker_process_query because it may have
5137	  been deleted by that routine.
5138	- Prime response state.
5139	- Process target response state.
5140	- some memcmp changed to dname_compare for case preservation.
5141
51421 June 2007: Wouter
5143	- normalize incoming messages. Like unbound-java, with CNAME chain
5144	  checked, DNAME checked, CNAME's synthesized, glue checked.
5145	- sanitize incoming messages.
5146	- split msgreply encode functions into own file msgencode.c.
5147	- msg_parse to queryinfo/replyinfo conversion more versatile.
5148	- process_response, classify response, delegpt_from_message.
5149
515031 May 2007: Wouter
5151	- querytargets state.
5152	- dname_subdomain_c() routine.
5153	- server selection, based on RTT. ip6 is filtered out if not available,
5154	  and lameness is checked too.
5155	- delegation point copy routine.
5156
515730 May 2007: Wouter
5158	- removed FLAG_CD from message and rrset caches. This was useful for
5159	  an agnostic forwarder, but not for a sophisticated (trust value per
5160	  rrset enabled) cache.
5161	- iterator reponse typing.
5162	- iterator cname handle.
5163	- iterator prime start.
5164	- subquery work.
5165	- processInitRequest and processInitRequest2.
5166	- cache synthesizes referral messages, with DS and NSEC.
5167	- processInitRequest3.
5168	- if a request creates multiple subrequests these are all activated.
5169
517029 May 2007: Wouter
5171	- routines to lock and unlock array of rrsets moved to cache/rrset.
5172	- lookup message from msg cache (and copy to region).
5173	- fixed cast error in dns msg lookup.
5174	- message with duplicate rrset does not increase its TTLs twice.
5175	- 'qnamesize' changed to 'qname_len' for similar naming scheme.
5176
517725 May 2007: Wouter
5178	- Acknowledge use of unbound-java code in iterator. Nicer readme.
5179	- services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
5180	  rrset cache from module environment.
5181	- packed rrset key has type and class as easily accessable struct
5182	  members. They are still kept in network format for fast msg encode.
5183	- dns cache find_delegation routine.
5184	- iterator main functions setup.
5185	- dns cache lookup setup.
5186

5193
519423 May 2007: Wouter
5195	- outside network does precise timers for roundtrip estimates for rtt
5196	  and for setting timeout for UDP. Pending_udp takes milliseconds.
5197	- cleaner iterator sockaddr conversion of forwarder address.
5198	- iterator/iter_utils and iter_delegpt setup.
5199	- root hints.
5200

5203	  outbound entry to the module.
5204	- testbound support for new serviced queries.
5205	- test for retry to TCP cannot use testbound any longer.

5207	- fixes for no-locking compile.
5208	- mini_event timer precision and fix for change in timeouts during
5209	  timeout callback. Fix for fwd_three tests, performed nonexit query.
5210
521121 May 2007: Wouter
5212	- small comment on hash table locking.
5213	- outside network serviced queries, contain edns and tcp fallback,
5214	  and udp retries and rtt timing.
5215
521616 May 2007: Wouter
5217	- lruhash_touch() would cause locking order problems. Fixup in
5218	  lock-verify in case locking cycle is found.
5219	- services/cache/rrset.c for rrset cache code.
5220	- special rrset_cache LRU updating function that uses the rrset id.

5262	- EDNS read from query, used to make reply smaller.
5263	- advertised edns value constants.
5264	- EDNS BADVERS response, if asked for too high edns version.
5265	- EDNS extended error reponses once the EDNS record from the query
5266	  has successfully been parsed.
5267
52684 May 2007: Wouter
5269	- msgreply sizefunc is more accurate.

5272	  alloc cache to store released keys.
5273	- alloc cache special_release() locks if necessary.
5274	- rrset trustworthiness type added.
5275	- thread keeps a scratchpad region for handling messages.

5290	- more dname unit tests.
5291	- message encoding creates truncated TC flagged messages if they do
5292	  not fit, and will leave out (whole)rrsets from additional if needed.
5293
52941 May 2007: Wouter
5295	- decompress query section, extremely lenient acceptance.
5296	  But only for answers from other servers, not for plain queries.
5297	- compression and decompression test cases.
5298	- some stats added.
5299	- example.conf interface: line is changed from 127.0.0.1 which leads
5300	  to problems if used (restricting communication to the localhost),
5301	  to a documentation and test address.
5302
530327 April 2007: Wouter
5304	- removed iov usage, it is not good for dns message encoding.

5355		* dname_pkt_copy forgot to read next label length.
5356	- test from file and fixes
5357		* double frees fixed in error conditions.
5358		* types with less than full rdata allowed by parser.
5359		  Some dynamic update packets seem to use it.

5500	- Testbed works with threading (different machines, different options).
5501	- alloc work, does the special type.
5502
55032 March 2007: Wouter

5505	  type errors as their typedefs have not been enabled.
5506	- log shows thread numbers much more nicely (and portably).
5507	- even on systems with nonthreadsafe libevent signal handling,

5518	- ub_thread_join portable definition.
5519	- forking is used if no threading is available.
5520	  Tested, it works, since pipes work across processes as well.
5521	  Thread_join is replaced with waitpid.
5522	- During reloads the daemon will temporarily handle signals,
5523	  so that they do not result in problems.
5524	- Also randomize the outgoing port range for tests.
5525	- If query list is full, will stop selecting listening ports for read.
5526	  This makes all threads service incoming requests, instead of one.
5527	  No memory is leaking during reloads, service of queries, etc.
5528	- test that uses ldns-testns -f to test threading. Have to answer
5529	  three queries at the same time.
5530	- with verbose=0 operates quietly.
5531
553226 February 2007: Wouter
5533	- ub_random code used to select ID and port.
5534	- log code prints thread id.
5535	- unbound can thread itself, with reload(HUP) and quit working
5536	  correctly.
5537	- don't open pipes for #0, doesn't need it.
5538	- listens to SIGTERM, SIGQUIT, SIGINT (all quit) and SIGHUP (reload).
5539
554023 February 2007: Wouter
5541	- Can do reloads on sigHUP. Everything is stopped, and freed,
5542	  except the listening ports. Then the config file is reread.
5543	  And everything is started again (and listening ports if needed).
5544	- Ports for queries are shared.
5545	- config file added interface:, chroot: and username:.
5546	- config file: directory, logfile, pidfile. And they work too.
5547	- will daemonize by default now. Use -d to stay in the foreground.
5548	- got BSD random[256 state] code, made it threadsafe. util/random.
5549
555022 February 2007: Wouter
5551	- Have a config file. Removed commandline options, moved to config.

555820 February 2007: Wouter
5559	- Added locks code and pthread spinlock detection.
5560	- can use no locks, or solaris native thread library.
5561	- added yacc and lex configure, and config file parsing code.
5562	  also makedist.sh, and manpage.
5563	- put include errno.h in config.h
5564
556519 February 2007: Wouter
5566	- Created 0.0 svn tag.
5567	- added acx_pthread.m4 autoconf check for pthreads from
5568	  the autoconf archive. It is GPL-with-autoconf-exception Licensed.
5569	  You can specify --with-pthreads, or --without-pthreads to configure.
5570
557116 February 2007: Wouter
5572	- Updated testbed script, works better by using make on remote end.
5573	- removed check decls, we can compile without them.
5574	- makefile supports LIBOBJ replacements.
5575	- docs checks ignore compat code.
5576	- added util/mini-event.c and .h, a select based alternative used with
5577	  ./configure --with-libevent=no
5578	  It is limited to 1024 file descriptors, and has less features.
5579	- will not create ip6 sockets if ip6 not on the machine.
5580
558115 February 2007: Wouter
5582	- port to FreeBSD 4.11 Dec Alpha. Also works on Solaris 10 sparc64,
5583	  Solaris 9, FreeBSD 6, Linux i386 and OSX powerpc.
5584	- malloc rndstate, so that it is aligned for access.
5585	- fixed rbtree cleanup with postorder traverse.
5586	- fixed pending messages are deleted when handled.
5587	- You can control verbosity; default is not verbose, every -v
5588	  adds more verbosity.
5589
559014 February 2007: Wouter
5591	- Included configure.ac changes from ldns.
5592	- detect (some) headers before the standards check.
5593	- do not use isblank to test c99, since its not available on solaris9.
5594	- review of testcode.
5595		* entries in a RANGE are no longer reversed.
5596		* print name of file with replay entry parse errors.
5597	- port to OSX: cast to int for some prints of sizet.
5598	- Makefile copies ldnstestpkts.c before doing dependencies on it.
5599

56197 February 2007: Wouter
5620	- return answer with the same ID as query was sent with.
5621	- created udp forwarder test. I've done some effort to make it perform
5622	  quickly. After servers are created, no big sleep statements but
5623	  it checks the logfiles to see if servers have come up. Takes 0.14s.
5624	- set addrlen value when calling recvfrom.
5625	- comparison of addrs more portable.
5626	- LIBEVENT option for testbed to set libevent directory.
