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

300	  unbound_cache.cmd: saves and loads the cache.
301	- Added unbound-control-setup.cmd from Yuri Voinov to the windows
302	  unbound distribution set.  It requires openssl installed in %PATH%.

31129 April 2014: Wouter
312	- iana portlist updated.
313	- Add unbound-control flush_negative that flushed nxdomains, nodata,

315	  fixes cases where network changes have localdata that was already
316	  negatively cached from the previous network.
317
31823 April 2014: Wouter
319	- Patch from Jeremie Courreges-Anglas to use arc4random_uniform

324
32511 April 2014: Wouter

338	  +i annotation in output of list_forwards, also for list_stubs
339	  (for NetworkManager integration.)
340	- Fix #554: use unsigned long to print 64bit statistics counters on
341	  64bit systems.
342	- Fix #558: failed prefetch lookup does not remove cached response
343	  but delays next prefetch (in lieu of caching a SERVFAIL).
344	- Fix #545: improved logging, the ip address of the error is printed
345	  on the same log-line as the error.

380
38120 February 2014: Matthijs
382	- Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
383	  received. This is okay according 4035, but not after revising
384	  existence in 4592.  NSEC empty non-terminals exist and thus the
385	  RCODE should have been NOERROR. If this occurs, and the RRsets
386	  are secure, we set the RCODE to NOERROR and the security status
387	  of the reponse is also considered secure.
388
38914 February 2014: Wouter
390	- Works on Minix (3.2.1).
391

423	  parse sldns.
424
42530 January 2014: Wouter
426	- delay-close does not act if there are udp-wait queries, so that
427	  it does not make a socketdrain DoS easier.
428
42928 January 2014: Wouter
430	- iana portlist updated.
431	- iana portlist test updated so it does not touch the source
432	  if there are no changes.
433	- delay-close: msec option that delays closing ports for which
434	  the UDP reply has timed out.  Keeps the port open, only accepts
435	  the correct reply.  This correct reply is not used, but the port
436	  is open so that no port-denied ICMPs are generated.
437
43827 January 2014: Wouter
439	- reuseport is attempted, then fallback to without on failure.
440
44124 January 2014: Wouter

498	  more specific interface port 53 can be used at the same time, and
499	  one of the daemons is unbound.
500	- iana portlist update.
501	- separate ldns into core ldns inside ldns/ subdirectory.  No more
502	  --with-ldns is needed and unbound does not rely on libldns.
503	- portability fixes for new USE_SLDNS ldns subdir codebase.
504
50522 Oct 2013: Wouter
506	- Patch from Neel Goyal: Add an API call to set an event base on an
507	  existing ub_ctx.  This basically just destroys the current worker and
508	  sets the event base to the current.  And fix a deadlock in
509	  ub_resolve_event – the cfglock is held when libworker_create is
510	  called.  This ends up trying to acquire the lock again in
511	  context_obtain_alloc in the call chain.
512	- Fix #528: if very high logging (4 or more) segfault on allow_snoop.
513
51426 Sep 2013: Wouter
515	- unbound-event.h is installed if configured --with-libevent.  It
516	  contains low-level library calls, that use libevent's event_base
517	  and an ldns_buffer for the wire return packet to perform async
518	  resolution in the client's eventloop.
519

99919 March 2012: Wouter
1000	- iana portlist updated.
1001	- fix to locate nameservers for DS lookup with NS fetches.
1002
100316 March 2012: Wouter
1004	- Patch for access to full DNS packet data in unbound python module
1005	  from Ondrej Mikle.
1006
10079 March 2012: Wouter
1008	- Applied line-buffer patch from Augie Schwer to validation.reporter.sh.
1009
10102 March 2012: Wouter
1011	- flush_infra cleans timeouted servers from the cache too.
1012	- removed warning from --enable-ecdsa.
1013
10141 March 2012: Wouter
1015	- forward-first option.  Tries without forward if a query fails.
1016	  Also stub-first option that is similar.
1017
101828 February 2012: Wouter
1019	- Fix from code review, if EINPROGRESS not defined chain if statement
1020	  differently.
1021
102227 February 2012: Wouter
1023	- Fix bug#434: on windows check registry for config file location
1024	  for unbound-control.exe, and unbound-checkconf.exe.
1025
102623 February 2012: Wouter
1027	- Fix to squelch 'network unreachable' errors from tcp connect in
1028	  logs, high verbosity will show them.
1029
103016 February 2012: Wouter
1031	- iter_hints is now thread-owned in module env, and thus threadsafe.
1032	- Fix prefetch and sticky NS, now the prefetch works.  It picks
1033	  nameservers that 'would be valid in the future', and if this makes
1034	  the NS timeout, it updates that NS by asking delegation from the
1035	  parent again.  If child NS has longer TTL, that TTL does not get
1036	  refreshed from the lookup to the child nameserver.
1037
103815 February 2012: Wouter
1039	- Fix forward-zone memory, uses malloc and frees original root dp.
1040	- iter hints (stubs) uses malloc inside for more dynamicity.
1041	- unbound-control forward_add, forward_remove, stub_add, stub_remove
1042	  can modify stubs and forwards for running unbound (on mobile computer)
1043	  they can also add and remove domain-insecure for the zone.
1044
104514 February 2012: Wouter
1046	- Fix sticky NS (ghost domain problem) if prefetch is yes.
1047	- iter forwards uses malloc inside for more dynamicity.
1048
104913 February 2012: Wouter
1050	- RT#2955. Fix for cygwin compilation.
1051	- iana portlist updated.
1052
105310 February 2012: Wouter
1054	- Slightly smaller critical region in one case in infra cache.
1055	- Fix timeouts to keep track of query type, A, AAAA and other, if
1056	  another has caused timeout blacklist, different type can still probe.
1057	- unit test fix for nomem_cnametopos.rpl race condition.
1058
10599 February 2012: Wouter
1060	- Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
1061
10628 February 2012: Wouter
1063	- implement draft-ietf-dnsext-ecdsa-04; which is in IETF LC; This
1064	  implementation is experimental at this time and not recommended
1065	  for use on the public internet (the protocol numbers have not
1066	  been assigned).  Needs recent ldns with --enable-ecdsa.
1067	- fix memory leak in errorcase for DSA signatures.
1068	- iana portlist updated.
1069	- workaround for openssl 0.9.8 ecdsa sha2 and evp problem.
1070
10713 February 2012: Wouter
1072	- fix for windows, rename() is not posix compliant on windows.
1073
10742 February 2012: Wouter
1075	- 1.4.16 release tag.
1076	- svn trunk is 1.4.17 in development.
1077	- iana portlist updated.
1078
10791 February 2012: Wouter
1080	- Fix validation failures (like: validation failure xx: no NSEC3
1081	  closest encloser from yy for DS zz. while building chain of trust,
1082	  because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
1083	  for an NSEC3.  Now it does not change rdata, and fixes TTL.
1084
108530 January 2012: Wouter
1086	- Fix version-number in libtool to be version-info so it produces
1087	  libunbound.so.2 like it should.
1088
108926 January 2012: Wouter
1090	- Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.
1091	- trunk 1.4.16; includes changes memset testcode, #424 openindiana,
1092	  and keyfile write fixup.
1093	- applied patch to support outgoing-interface with ub_ctx_set_option.
1094
109523 January 2012: Wouter
1096	- Fix memset in test code.
1097
109820 January 2012: Wouter
1099	- Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
1100
110119 January 2012: Wouter
1102	- Fix to write key files completely to a temporary file, and if that
1103	  succeeds, replace the real key file.  So failures leave a useful file.
1104
110518 January 2012: Wouter
1106	- tag 1.4.15rc1 created
1107	- updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
1108
110917 January 2012: Wouter
1110	- Fix bug where canonical_compare of RRSIG did not downcase the
1111	  signer-name.  This is mostly harmless because RRSIGs do not have
1112	  to be sorted in canonical order, usually.
1113
111412 January 2012: Wouter
1115	- bug#428: add ub_version() call to libunbound.  API version increase,
1116	  with (binary) backwards compatibility for the previous version.
1117
111810 January 2012: Wouter
1119	- Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
1120	  that would be permissible by the RFCs but it is not the TTL in the
1121	  cache.
1122	- iana portlist updated.
1123	- uninitialised variable in reprobe for rtt blocked domains fixed.
1124	- lintfix and new flex output.
1125
11262 January 2012: Wouter
1127	- Fix to randomize hash function, based on 28c3 congress, reported
1128	  by Peter van Dijk.
1129
113024 December 2011: Wouter
1131	- Fix for memory leak (about 20 bytes when a tcp or udp send operation
1132	  towards authority servers failed, takes about 50.000 such failures to
1133	  leak one Mb, such failures are also usually logged), reported by
1134	  Robert Fleischmann.
1135	- iana portlist updated.
1136
113719 December 2011: Wouter
1138	- Fix for VU#209659 CVE-2011-4528: Unbound denial of service
1139	  vulnerabilities from nonstandard redirection and denial of existence
1140	  http://www.unbound.net/downloads/CVE-2011-4528.txt
1141	- robust checks for next-closer NSEC3s.
1142	- tag 1.4.14 created.

1146	- remove uninit warning from cachedump code.
1147	- Fix parse error on negative SOA RRSIGs if badly ordered in the packet.
1148
114913 December 2011: Wouter
1150	- iana portlist updated.
1151	- svn tag 1.4.14rc1
1152	- fix infra cache comparison.
1153	- Fix to constrain signer_name to be a parent of the lookupname.
1154
11555 December 2011: Wouter
1156	- Fix getaddrinfowithincludes on windows with fedora16 mingw32-gcc.

1163
116430 November 2011: Wouter
1165	- Fix for tcp-upstream and ssl-upstream for if a laptop sleeps, causes
1166	  SERVFAILs.  Also fixed for UDP (but less likely).
1167
116828 November 2011: Wouter
1169	- Fix quartile time estimate, it was too low, (thanks Jan Komissar).
1170	- iana ports updated.
1171

1174	- iana ports updated.
1175
117610 November 2011: Wouter
1177	- Makefile changed for BSD make compatibility.
1178
11799 November 2011: Wouter
1180	- added unit test for SSL service and SSL-upstream.
1181
11828 November 2011: Wouter
1183	- can configure ssl service to one port number, and not on others.
1184	- fixup windows compile with ssl support.
1185	- Fix double free in unbound-host, reported by Steve Grubb.
1186	- iana portlist updated.
1187
11881 November 2011: Wouter
1189	- dns over ssl support as a client, ssl-upstream yes turns it on.
1190	  It performs an SSL transaction for every DNS query (250 msec).
1191	- documentation for new options: ssl-upstream, ssl-service-key and
1192	  ssl-service.pem.
1193	- iana portlist updated.
1194	- fix -flto detection on Lion for llvm-gcc.
1195
119631 October 2011: Wouter
1197	- dns over ssl support, ssl-service-pem and ssl-service-key files
1198	  can be given and then TCP queries are serviced wrapped in SSL.
1199
120027 October 2011: Wouter
1201	- lame-ttl and lame-size options no longer exist, it is integrated
1202	  with the host info.  They are ignored (with verbose warning) if
1203	  encountered to keep the config file backwards compatible.
1204	- fix iana-update for changing gzip compression of results.
1205	- fix export-all-symbols on OSX.
1206
120726 October 2011: Wouter

1212
121324 October 2011: Wouter
1214	- Fix resolve of partners.extranet.microsoft.com with a fix for the
1215	  server selection for choosing out of a (particular) list of bad
1216	  choices. (bug#415)
1217	- Fix make_new_space function so that the incoming query is not
1218	  overwritten if a jostled out query causes a waiting query to be
1219	  resumed that then fails and sends an error message.  (Thanks to
1220	  Matthew Lee).
1221
122221 October 2011: Wouter
1223	- fix --enable-allsymbols, fptr wlist is disabled on windows with this
1224	  option enabled because of memory layout exe vs dll.
1225
122619 October 2011: Wouter
1227	- fix unbound-anchor for broken strptime on OSX lion, detected
1228	  in configure.
1229	- Detect if GOST really works, openssl1.0 on OSX fails.
1230	- Implement ipv6%interface notation for scope_id usage.
1231
123217 October 2011: Wouter
1233	- better documentation for inform_super (Thanks Yang Zhe).
1234
123514 October 2011: Wouter
1236	- Fix for out-of-memory condition in libunbound (thanks
1237	  Robert Fleischman).
1238
123913 October 2011: Wouter
1240	- Fix --enable-allsymbols, it depended on link specifics of the
1241	  target platform, or fptr_wlist assertion failures could occur.
1242
124312 October 2011: Wouter
1244	- updated contrib/unbound_munin_ to family=auto so that it works with
1245	  munin-node-configure automatically (if installed as
1246	  /usr/local/share/munin/plugins/unbound_munin_ ).
1247
124827 September 2011: Wouter
1249	- unbound.exe -w windows option for start and stop service.
1250
125123 September 2011: Wouter
1252	- TCP-upstream calculates tcp-ping so server selection works if there
1253	  are alternatives.
1254
125520 September 2011: Wouter
1256	- Fix classification of NS set in answer section, where there is a
1257	  parent-child server, and the answer has the AA flag for dir.slb.com.
1258	  Thanks to Amanda Constant from Secure64.
1259
126016 September 2011: Wouter
1261	- fix bug #408: accept patch from Steve Snyder that comments out
1262	  unused functions in lookup3.c.
1263	- iana portlist updated.
1264	- fix EDNS1480 change memleak and TCP fallback.
1265	- fix various compiler warnings (reported by Paul Wouters).
1266	- max sent count.  EDNS1480 only for rtt < 5000.  No promiscuous
1267	  fetch if sentcount > 3, stop query if sentcount > 16.  Count is
1268	  reset when referral or CNAME happens.  This makes unbound better
1269	  at managing large NS sets, they are explored when there is continued
1270	  interest (in the form of queries).
1271
127215 September 2011: Wouter
1273	- release 1.4.13.
1274	- trunk contains 1.4.14 in development.
1275	- Unbound probes at EDNS1480 if there an EDNS0 timeout.
1276
127712 September 2011: Wouter
1278	- Reverted dns EDNS backoff fix, it did not help and needs
1279	  fragmentation fixes instead.
1280	- tag 1.4.13rc2
1281
12827 September 2011: Wouter
1283	- Fix operation in ipv6 only (do-ip4: no) mode.
1284
12856 September 2011: Wouter
1286	- fedora specfile updated.
1287
12885 September 2011: Wouter
1289	- tag 1.4.13rc1
1290
12912 September 2011: Wouter
1292	- iana portlist updated.
1293
129426 August 2011: Wouter
1295	- Fix num-threads 0 does not segfault, reported by Simon Deziel.
1296	- Fix validation failures due to EDNS backoff retries, the retry
1297	  for fetch of data has want_dnssec because the iter_indicate_dnssec
1298	  function returns true when validation failure retry happens, and
1299	  then the serviced query code does not fallback to noEDNS, even if
1300	  the cache says it has this.  This helps for DLV deployment when
1301	  the DNSSEC status is not known for sure before the lookup concludes.
1302
130324 August 2011: Wouter
1304	- Applied patch from Karel Slany that fixes a memory leak in the
1305	  unbound python module, in string conversions.
1306
130722 August 2011: Wouter
1308	- Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
1309	  Zhang and Luo Ce).  Unbound responds with the RR types that are
1310	  available at the name for qtype ANY and validates those RR types.
1311	  It does not test for completeness (i.e. with NSEC or NSEC3 query),
1312	  and it does not follow the CNAME or DNAME to another name (with
1313	  even more data for the already large response).
1314	- Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
1315	- Documented the options that work with control set_option command.
1316	- tcp-upstream yes/no option (works with set_option) for tunnels.
1317
131818 August 2011: Wouter
1319	- fix autoconf call in makedist crosscompile to RC or snapshot.
1320
132117 August 2011: Wouter
1322	- Fix validation of . DS query.
1323	- new xml format at IANA, new awk for iana_update.
1324	- iana portlist updated.
1325
132610 August 2011: Wouter
1327	- Fix python site-packages path to /usr/lib64.
1328	- updated patch from Tom.
1329	- fix memory and fd leak after out-of-memory condition.
1330
13319 August 2011: Wouter
1332	- patch from Tom Hendrikx fixes load of python modules.
1333
13348 August 2011: Wouter
1335	- make clean had ldns-src reference, removed.
1336
13371 August 2011: Wouter
1338	- Fix autoconf 2.68 warnings
1339
134014 July 2011: Wouter
1341	- Unbound implements RFC6303 (since version 1.4.7).
1342	- tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
1343	  meantime, those are for 1.4.13).
1344	- iana portlist updated.
1345
134613 July 2011: Wouter
1347	- Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
1348
134911 July 2011: Wouter
1350	- Fix wildcard expansion no-data reply under an optout NSEC3 zone is
1351	  validated as insecure, reported by Jia Li (lijia@cnnic.cn).
1352
13534 July 2011: Wouter
1354	- 1.4.12rc1 tag created.
1355
13561 July 2011: Wouter
1357	- version number in example config file.
1358	- fix that --enable-static-exe does not complain about it unknown.
1359
136030 June 2011: Wouter
1361	- tag relase 1.4.11, trunk is 1.4.12 development.
1362	- iana portlist updated.
1363	- fix bug#395: id bits of other query may leak out under conditions
1364	- fix replyaddr count wrong after jostled queries, which leads to
1365	  eventual starvation where the daemon has no replyaddrs left to use.
1366	- fix comment about rndc port, that referred to the old port number.
1367	- fix that the listening socket is not closed when too many remote
1368	  control connections are made at the same time.
1369	- removed ldns-src tarball inside the unbound tarball.
1370
137123 June 2011: Wouter
1372	- Changed -flto check to support clang compiler.
1373	- tag 1.4.11rc3 created.
1374
137517 June 2011: Wouter
1376	- tag 1.4.11rc1 created.
1377	- remove warning about signed/unsigned from flex (other flex version).
1378	- updated aclocal.m4 and libtool to match.
1379	- tag 1.4.11rc2 created.
1380
138116 June 2011: Wouter
1382	- log-queries: yesno option, default is no, prints querylog.
1383	- version is 1.4.11.
1384
138514 June 2011: Wouter
1386	- Use -flto compiler flag for link time optimization, if supported.
1387	- iana portlist updated.
1388
138912 June 2011: Wouter
1390	- IPv6 service address for d.root-servers.net (2001:500:2D::D).
1391
139210 June 2011: Wouter
1393	- unbound-control has version number in the header,
1394	  UBCT[version]_space_ is the header sent by the client now.
1395	- Unbound control port number is registered with IANA:
1396	  ub-dns-control  8953/tcp    unbound dns nameserver control
1397	  This is the new default for the control-port config setting.
1398	- statistics-interval prints the number of jostled queries to log.
1399
140030 May 2011: Wouter
1401	- Fix Makefile for U in environment, since wrong U is more common than
1402	  deansification necessity.
1403	- iana portlist updated.
1404	- updated ldns tarball to 1.6.10rc2 snapshot of today.
1405
140625 May 2011: Wouter
1407	- Fix assertion failure when unbound generates an empty error reply
1408	  in response to a query, CVE-2011-1922 VU#531342.
1409	- This fix is in tag 1.4.10.
1410	- defense in depth against the above bug, an error is printed to log
1411	  instead of an assertion failure.
1412
141310 May 2011: Wouter
1414	- bug#386: --enable-allsymbols option links all binaries to libunbound
1415	  and reduces install size significantly.
1416	- feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
1417	- iana portlist updated.
1418	- Fix TTL of SOA so negative TTL is separately cached from normal TTL.
1419
142014 April 2011: Wouter
1421	- configure created with newer autoconf 2.66.
1422
142312 April 2011: Wouter
1424	- bug#378: Fix that configure checks for ldns_get_random presence.
1425
14268 April 2011: Wouter
1427	- iana portlist updated.
1428	- queries with CD flag set cause DNSSEC validation, but the answer is
1429	  not withheld if it is bogus.  Thus, unbound will retry if it is bad
1430	  and curb the TTL if it is bad, thus protecting the cache for use by
1431	  downstream validators.
1432	- val-override-date: -1 ignores dates entirely, for NTP usage.
1433
143429 March 2011: Wouter
1435	- harden-below-nxdomain: changed so that it activates when the
1436	  cached nxdomain is dnssec secure.  This avoids backwards
1437	  incompatibility because those old servers do not have dnssec.
1438
143924 March 2011: Wouter
1440	- iana portlist updated.
1441	- release 1.4.9.
1442	- trunk is 1.5.0
1443
144417 March 2011: Wouter
1445	- bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
1446	  Applied but did not do the --disable-gost.
1447
144810 March 2011: Wouter
1449	- tag 1.4.9 release candidate 1 created.
1450

1476	- tpkg updated with common.sh for common functionality.
1477
14787 February 2011: Wouter

1480	  cache effects with different TTL for glue and DNSKEY.
1481	- iana portlist updated.
1482

1498	- iana portlist updated.
1499
150014 January 2011: Wouter
1501	- Fix so a changed NS RRset does not get moved name stuck on old
1502	  server, for type NS the TTL is not increased.
1503
150413 January 2011: Wouter
1505	- Fix prefetch so it does not get stuck on old server for moved names.
1506
150712 January 2011: Wouter
1508	- iana portlist updated.
1509

1522	- Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
1523
152421 December 2010: Wouter
1525	- algorithm compromise protection using the algorithms signalled in
1526	  the DS record.  Also, trust anchors, DLV, and RFC5011 receive this,
1527	  and thus, if you have multiple algorithms in your trust-anchor-file
1528	  then it will now behave different than before.  Also, 5011 rollover
1529	  for algorithms needs to be double-signature until the old algorithm
1530	  is revoked.
1531	  It is not an option, because I see no use to turn the security off.
1532	- iana portlist updated.
1533
153417 December 2010: Wouter
1535	- squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
1536	- fix validation in this case: CNAME to nodata for co-hosted opt-in
1537	  NSEC3 insecure delegation, was bogus, fixed to be insecure.
1538
153916 December 2010: Wouter
1540	- Fix our 'BDS' license (typo reported by Xavier Belanger).
1541
154210 December 2010: Wouter

1544	- review changes for unbound-anchor.
1545
15462 December 2010: Wouter
1547	- feature typetransparent localzone, does not block other RR types.
1548

1551
155230 November 2010: Wouter
1553	- Fix storage of EDNS failures in the infra cache.
1554	- iana portlist updated.
1555
155618 November 2010: Wouter
1557	- harden-below-nxdomain option, default off (because very old
1558	  software may be incompatible).  We could enable it by default in
1559	  the future.
1560
156117 November 2010: Wouter
1562	- implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
1563	- make test output nicer.
1564
156515 November 2010: Wouter
1566	- silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
1567	- iana portlist updated.
1568	- so-sndbuf option for very busy servers, a bit like so-rcvbuf.
1569
15709 November 2010: Wouter
1571	- unbound-anchor compiles with openssl 0.9.7.
1572
15738 November 2010: Wouter
1574	- release tag 1.4.7.
1575	- trunk is version 1.4.8.
1576	- Be lenient and accept imgw.pl malformed packet (like BIND).
1577
15785 November 2010: Wouter
1579	- do not synthesize a CNAME message from cache for qtype DS.
1580
15814 November 2010: Wouter
1582	- Use central entropy to seed threads.
1583
15843 November 2010: Wouter
1585	- Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
1586
15872 November 2010: Wouter

1589	- code review.
1590
15911 November 2010: Wouter

1593
159427 October 2010: Wouter
1595	- Fix uninit value in dump_infra print.
1596	- Fix validation failure for parent and child on same server with an
1597	  insecure childzone and a CNAME from parent to child.
1598	- Configure detects libev-4.00.
1599
160026 October 2010: Wouter
1601	- dump_infra and flush_infra commands for unbound-control.
1602	- no timeout backoff if meanwhile a query succeeded.
1603	- Change of timeout code.  No more lost and backoff in blockage.
1604	  At 12sec timeout (and at least 2x lost before) one probe per IP
1605	  is allowed only.  At 120sec, the IP is blocked.  After 15min, a
1606	  120sec entry has a single retry packet.
1607
160825 October 2010: Wouter
1609	- Configure errors if ldns is not found.
1610
161122 October 2010: Wouter
1612	- Windows 7 fix for the installer.
1613
161421 October 2010: Wouter
1615	- Fix bug where fallback_tcp causes wrong roundtrip and edns
1616	  observation to be noted in cache.  Fix bug where EDNSprobe halted
1617	  exponential backoff if EDNS status unknown.
1618	- new unresponsive host method, exponentially increasing block backoff.
1619	- iana portlist updated.
1620
162120 October 2010: Wouter
1622	- interface automatic works for some people with ip6 disabled.
1623	  Therefore the error check is removed, so they can use the option.
1624
162519 October 2010: Wouter
1626	- Fix for request list growth, if a server has long timeout but the
1627	  lost counter is low, then its effective rtt is the one without
1628	  exponential backoff applied.  Because the backoff is not working.
1629	  The lost counter can then increase and the server is blacklisted,
1630	  or the lost counter does not increase and the server is working
1631	  for some queries.
1632
163318 October 2010: Wouter
1634	- iana portlist updated.
1635
163613 October 2010: Wouter
1637	- Fix TCP so it uses a random outgoing-interface.
1638	- unbound-anchor handles ADDPEND keystate.
1639
164011 October 2010: Wouter
1641	- Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
1642	  the zone has a secure delegation hosted on the same server did not
1643	  verify as secure (it was insecure by mistake).
1644	- iana portlist updated.
1645	- ldns tarball updated (for reading cachedumps with bad RR data).
1646
16471 October 2010: Wouter
1648	- test for unbound-anchor. fix for reading certs.
1649	- Fix alloc_reg_release for longer uptime in out of memory conditions.
1650
165128 September 2010: Wouter
1652	- unbound-anchor working, it creates or updates a root.key file.
1653	  Use it before you start the validator (e.g. at system boot time).
1654
165527 September 2010: Wouter
1656	- iana portlist updated.
1657
165824 September 2010: Wouter

1660
166123 September 2010: Wouter
1662	- unbound-anchor app, unbound requires libexpat (xml parser library).
1663
166422 September 2010: Wouter
1665	- compliance with draft-ietf-dnsop-default-local-zones-14, removed
1666	  reverse ipv6 orchid prefix from builtin list.

1670	- DLV has downgrade protection again, because the RFC says so.
1671	- iana portlist updated.
1672
167316 September 2010: Wouter
1674	- Algorithm rollover operational reality intrudes, for trust-anchor,
1675	  5011-store, and DLV-anchor if one key matches it's good enough.
1676	- iana portlist updated.
1677	- Fix reported validation error in out of memory condition.
1678
167915 September 2010: Wouter
1680	- Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
1681
168214 September 2010: Wouter
1683	- increased mesh-max-activation from 1000 to 3000 for crazy domains
1684	  like _tcp.slb.com with 262 servers.
1685	- iana portlist updated.
1686
168713 September 2010: Wouter
1688	- bug#327: Fix for cannot access stub zones until the root is primed.
1689
16909 September 2010: Wouter
1691	- unresponsive servers are not completely blacklisted (because of
1692	  firewalls), but also not probed all the time (because of the request
1693	  list size it generates).  The probe rate is 1%.
1694	- iana portlist updated.
1695
169620 August 2010: Wouter
1697	- openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
1698	  iterator get_mem includes priv_get_mem.  delegpt nodup removed.

1712	  if use sun-cc, but some systems need different flags.
1713
171416 August 2010: Wouter
1715	- Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
1716	  changes, uses m4_bpatsubst now.
1717	- make test (or make check) should be more portable and run the unit
1718	  test and testbound scripts. (make longtest has special requirements).
1719
172013 August 2010: Wouter
1721	- More pleasant remote control command parsing.
1722	- documentation added for return values reported by doxygen 1.7.1.
1723	- iana portlist updated.
1724
17259 August 2010: Wouter

1733	  unsupported algorithms.
1734
17353 August 2010: Wouter

1737	- release tag 1.4.6.
1738	- trunk becomes 1.4.7 develop.
1739	- iana portlist updated.
1740
174122 July 2010: Wouter
1742	- more error details on failed remote control connection.
1743
174415 July 2010: Wouter
1745	- rlimit adjustments for select and ulimit can happen at the same time.
1746
174714 July 2010: Wouter
1748	- Donation text added to README.
1749	- Fix integer underflow in prefetch ttl creation from cache.  This
1750	  fixes a potential negative prefetch ttl.
1751
175212 July 2010: Wouter
1753	- Changed the defaults for num-queries-per-thread/outgoing-range.
1754	  For builtin-select: 512/960, for libevent 1024/4096 and for
1755	  windows 24/48 (because of win api).  This makes the ratio this way
1756	  to improve resilience under heavy load.  For high performance, use
1757	  libevent and possibly higher numbers.
1758
175910 July 2010: Wouter
1760	- GOST enabled if SSL is recent and ldns has GOST enabled too.
1761	- ldns tarball updated.
1762
17639 July 2010: Wouter
1764	- iana portlist updated.
1765	- Fix validation of qtype DNSKEY when a key-cache entry exists but
1766	  no rr-cache entry is used (it expired or prefetch), it then goes
1767	  back up to the DS or trust-anchor to validate the DNSKEY.
1768
17697 July 2010: Wouter
1770	- Neat function prototypes, unshadowed local declarations.
1771
17726 July 2010: Wouter
1773	- failure to chown the pidfile is not fatal any more.
1774	- testbound uses UTC timezone.
1775	- ldns tarball updated (ports and works on Minix 3.1.7).  On Minix, add
1776	  /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
1777
17785 July 2010: Wouter
1779	- log if a server is skipped because it is on the donotquery list,
1780	  at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
1781	- added feature to print configure date, target and options with -h.
1782	- added feature to print event backend system details with -h.
1783	- wdiff is not actually required by make test, updated requirements.
1784
17851 July 2010: Wouter
1786	- Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
1787	  must be signed with all algorithms from the DS rrset at the parent.
1788	  This is now checked and becomes bogus if not.
1789
179028 June 2010: Wouter
1791	- Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
1792	  in overload situations to be about 5 qps for the class of shortly
1793	  serviced queries.
1794	  The capacity of the resolver is then about (numqueriesperthread / 2)
1795	  / (average time for such long queries) qps for long queries.
1796	  And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
1797	  qps for short queries, per thread.
1798	- Fix the max number of reply-address count to be applied for duplicate
1799	  queries, and not for new query list entries.  This raises the memory
1800	  usage to a max of (16+1)*numqueriesperthread reply addresses.
1801
180225 June 2010: Wouter
1803	- Fix handling of corner case reply from lame server, follows rfc2308.
1804	  It could lead to a nodata reply getting into the cache if the search
1805	  for a non-lame server turned up other misconfigured servers.
1806	- unbound.h has extern "C" statement for easier include in c++.
1807
180823 June 2010: Wouter
1809	- iana portlist updated.
1810	- makedist upgraded cross compile openssl option, like this:

182017 June 2010: Wouter
1821	- Add AAAA to root hints for I.ROOT-SERVERS.NET.
1822
182316 June 2010: Wouter
1824	- Fix assertion failure reported by Kai Storbeck from XS4ALL, the
1825	  assertion was wrong.
1826	- updated ldns tarball.
1827
182815 June 2010: Wouter
1829	- tag 1.4.5 created.
1830	- trunk contains 1.4.6 in development.
1831	- Fix TCPreply on systems with no writev, if just 1 byte could be sent.
1832	- Fix to use one pointer less for iterator query state store_parent_NS.
1833	- makedist crosscompile to windows uses builtin ldns not host ldns.
1834	- Max referral count from 30 to 130, because 128 one character domains
1835	  is valid DNS.
1836	- added documentation for the histogram printout to syslog.
1837
183811 June 2010: Wouter
1839	- When retry to parent the retrycount is not wiped, so failed
1840	  nameservers are not tried again.
1841	- iana portlist updated.
1842
184310 June 2010: Wouter
1844	- Fix bug where a long loop could be entered, now cycle detection
1845	  has a loop-counter and maximum search amount.
1846
18474 June 2010: Wouter
1848	- iana portlist updated.
1849	- 1.4.5rc1 tag created.
1850
18513 June 2010: Wouter
1852	- ldns tarball updated, 1.6.5.
1853	- review comments, split dependency cycle tracking for parentside
1854	  last resort lookups for A and AAAA so there are more lookup options.
1855
18562 June 2010: Wouter
1857	- Fix compile warning if compiled without threads.
1858	- updated ldns-tarball with current ldns svn (pre 1.6.5).
1859	- GOST disabled-by-default, the algorithm number is allocated but the
1860	  RFC is still has to pass AUTH48 at the IETF.
1861
18621 June 2010: Wouter
1863	- Ignore Z flag in incoming messages too.
1864	- Fix storage of negative parent glue if that last resort fails.
1865	- libtoolize 2.2.6b, autoconf 2.65 applied to configure.
1866	- new splint flags for newer splint install.
1867
186831 May 2010: Wouter
1869	- Fix AD flag handling, it could in some cases mistakenly copy the AD
1870	  flag from upstream servers.
1871	- alloc_special_obtain out of memory is not a fatal error any more,
1872	  enabling unbound to continue longer in out of memory conditions.
1873	- parentside names are dispreferred but not said to be dnssec-lame.
1874	- parentside check for cached newname glue.
1875	- fix parentside and querytargets modulestate, for dump_requestlist.
1876	- unbound-control-setup makes keys -rw-r--- so not all users permitted.
1877	- fix parentside from cache to be marked dispreferred for bad names.
1878
187928 May 2010: Wouter
1880	- iana portlist updated.
1881	- parent-child disagreement approach altered.  Older fixes are
1882	  removed in place of a more exhaustive search for misconfigured data
1883	  available via the parent of a delegation.
1884	  This is designed to be throttled by cache entries, with TTL from the
1885	  parent if possible.  Additionally the loop-counter is used.
1886	  It also tests for NS RRset differences between parent and child.
1887	  The fetch of misconfigured data should be more reliable and thorough.
1888	  It should work reliably even with no or only partial data in cache.
1889	  Data received from the child (as always) is deemed more
1890	  authoritative than information received from the delegation parent.
1891	  The search for misconfigured data is not performed normally.
1892
189326 May 2010: Wouter
1894	- Contribution from Migiel de Vos (Surfnet): nagios patch for
1895	  unbound-host, in contrib/ (in the source tarball).  Makes
1896	  unbound-host suitable for monitoring dnssec(-chain) status.
1897
189821 May 2010: Wouter
1899	- EDNS timeout code will not fire if EDNS status already known.
1900	- EDNS failure not stored if EDNS status known to work.
1901
190219 May 2010: Wouter
1903	- Fix resolution for domains like safesvc.com.cn.  If the iterator
1904	  can not recurse further and it finds the delegation in a state
1905	  where it would otherwise have rejected it outhand if so received
1906	  from a cache lookup, then it can try to ask higherup (with loop
1907	  protection).
1908	- Fix comments in iter_utils:dp_is_useless.
1909
191018 May 2010: Wouter
1911	- Fix various compiler warnings from the clang llvm compiler.
1912	- iana portlist updated.
1913
19146 May 2010: Wouter
1915	- Fix bug#308: spelling error in variable name in parser and lexer.
1916
19174 May 2010: Wouter
1918	- Fix dnssec-missing detection that was turned off by server selection.
1919	- Conforms to draft-ietf-dnsop-default-local-zones-13.  Added default
1920	  reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
1921	  113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
1922
192329 April 2010: Wouter
1924	- Fix for dnssec lameness detection to use the key cache.
1925	- infra cache entries that are expired are wiped clean.  Previously
1926	  it was possible to not expire host data (if accessed often).
1927
192828 April 2010: Wouter
1929	- ldns tarball updated and GOST support is detected and then enabled.
1930	- iana portlist updated.
1931	- Fix detection of gost support in ldns (reported by Chris Smith).
1932
193327 April 2010: Wouter
1934	- unbound-control get_option domain-insecure shows config file items.
1935	- fix retry sequence if prime hints are recursion-lame.
1936	- autotrust anchor file can be initialized with a ZSK key as well.
1937	- harden-referral-path does not result in failures due to max-depth.
1938	  You can increase the max-depth by adding numbers (' 0') after the
1939	  target-fetch-policy, this increases the depth to which is checked.
1940
194126 April 2010: Wouter
1942	- Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
1943	  CPPFLAGS during configure process.
1944	- if libev is installed on the base system (not libevent), detect
1945	  it from the event.h header file and link with -lev.
1946	- configlexer.lex gets config.h, and configyyrename.h added by make,
1947	  no more double include.
1948	- More strict scrubber (Thanks to George Barwood for the idea):
1949	  NS set must be pertinent to the query (qname subdomain nsname).
1950	- Fix bug#307: In 0x20 backoff fix fallback so the number of
1951	  outstanding queries does not become -1 and block the request.
1952	  Fixed handling of recursion-lame in combination with 0x20 fallback.
1953	  Fix so RRsets are compared canonicalized and sorted if the immediate
1954	  comparison fails, this makes it work around round-robin sites.
1955
195623 April 2010: Wouter
1957	- Squelch log message: sendto failed permission denied for
1958	  255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
1959	- Fix to fetch data as last resort more tenaciously.  When cycle
1960	  targets cause the server selection to believe there are more options
1961	  when they really are not there, the server selection is reinitiated.
1962	- Fix fetch from blacklisted dnssec lame servers as last resort.  The
1963	  server's IP address is then given in validator errors as well.
1964	- Fix local-zone type redirect that did not use the query name for
1965	  the answer rrset.
1966
196722 April 2010: Wouter
1968	- tag 1.4.4.
1969	- trunk contains 1.4.5 in development.
1970	- Fix validation failure for qtype ANY caused by a RRSIG parse failure.
1971	  The validator error message was 'no signatures from ...'.
1972
197316 April 2010: Wouter
1974	- more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
1975	- tag 1.4.4rc1.
1976
197715 April 2010: Wouter
1978	- ECC-GOST algorithm number 12 that is assigned by IANA.  New test
1979	  example key and signatures for GOST.  GOST requires openssl-1.0.0.
1980	  GOST is still disabled by default.
1981
19829 April 2010: Wouter
1983	- Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
1984	  get into an endless loop, if 0x20 was enabled, and buffers are small
1985	  or particular broken packets are received.
1986	- Fix chain of trust with CNAME at an intermediate step, for the DS
1987	  processing proof.
1988
19898 April 2010: Wouter
1990	- Fix validation of queries with wildcard names (*.example).
1991
19926 April 2010: Wouter
1993	- Fix EDNS probe for .de DNSSEC testbed failure, where the infra
1994	  cache timeout coincided with a server update, the current EDNS
1995	  backoff is less sensitive, and does not cache the backoff unless
1996	  the backoff actually works and the domain is not expecting DNSSEC.
1997	- GOST support with correct algorithm numbers.
1998
19991 April 2010: Wouter
2000	- iana portlist updated.
2001
200224 March 2010: Wouter
2003	- unbound control flushed items are not counted when flushed again.
2004
200523 March 2010: Wouter
2006	- iana portlist updated.
2007
200822 March 2010: Wouter
2009	- unbound-host disables use-syslog from config file so that the
2010	  config file for the main server can be used more easily.
2011	- fix bug#301: unbound-checkconf could not parse interface
2012	  '0.0.0.0@5353', even though unbound itself worked fine.
2013
201419 March 2010: Wouter
2015	- fix fwd_ancil test to pass if the socket options are not supported.
2016
201718 March 2010: Wouter
2018	- Fixed random numbers for port, interface and server selection.
2019	  Removed very small bias.
2020	- Refer to the listing in unbound-control man page in the extended
2021	  statistics entry in the unbound.conf man page.
2022
202316 March 2010: Wouter
2024	- Fix interface-automatic for OpenBSD: msg.controllen was too small,
2025	  also assertions on ancillary data buffer.
2026	- check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
2027	- for NSEC3 check if signatures are cached.
2028
202915 March 2010: Wouter
2030	- unit test for util/regional.c.
2031
203212 March 2010: Wouter
2033	- Reordered configure checks so fork and -lnsl -lsocket checks are
2034	  earlier, and thus later checks benefit from and do not hinder them.
2035	- iana portlist updated.
2036	- ldns tarball updated.
2037	- Fix python use when multithreaded.
2038	- Fix solaris python compile.
2039	- Include less in config.h and include per code file for ldns, ssl.
2040
204111 March 2010: Wouter
2042	- another memory allocation option: --enable-alloc-nonregional.
2043	  exposes the regional allocations to other memory purifiers.
2044	- fix for memory alignment in struct sock_list allocation.
2045	- Fix for MacPorts ldns without ssl default, unbound checks if ldns
2046	  has dnssec functionality and uses the builtin if not.
2047	- Fix daemonize on Solaris 10, it did not detach from terminal.
2048	- tag 1.4.3 created.
2049	- trunk is 1.4.4 in development.
2050	- spelling fix in validation error involving cnames.
2051
205210 March 2010: Wouter
2053	- --enable-alloc-lite works with test set.
2054	- portability in the testset: printf format conversions, prototypes.
2055
20569 March 2010: Wouter
2057	- tag 1.4.2 created.
2058	- trunk is 1.4.3 in development.
2059	- --enable-alloc-lite debug option.
2060
20618 March 2010: Wouter
2062	- iana portlist updated.
2063
20644 March 2010: Wouter
2065	- Fix crash in control channel code.

2069	- iana portlist updated.
2070
20711 March 2010: Wouter
2072	- make install depends on make all.
2073	- Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
2074	- --enable-checking: enables assertions but does not look nonproduction.
2075	- nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
2076	  nxdomain and nodata distinguished.
2077	- ldns tarball updated.
2078	- --disable-rpath fixed for libtool not found errors.
2079	- new fedora specfile from Fedora13 in contrib from Paul Wouters.
2080
208126 February 2010: Wouter
2082	- Fixup prototype for lexer cleanup in daemon code.
2083	- unbound-control list_stubs, list_forwards, list_local_zones and
2084	  list_local_data.
2085
208624 February 2010: Wouter
2087	- Fix scrubber bug that potentially let NS records through.  Reported
2088	  by Amanda Constant.
2089	- Also delete potential poison references from additional.
2090	- Fix: no classification of a forwarder as lame, throw away instead.
2091
209223 February 2010: Wouter
2093	- libunbound ub_ctx_get_option() added.
2094	- unbound-control set_option and get_option commands.
2095	- iana portlist updated.
2096
209718 February 2010: Wouter
2098	- A little more strict DS scrubbing.
2099	- No more blacklisting of unresponsive servers, a 2 minute timeout
2100	  is backed off to.
2101	- RD flag not enabled for dnssec-blacklisted tries, unless necessary.
2102	- pickup ldns compile fix, libdl for libcrypto.
2103	- log 'tcp connect: connection timed out' only in high verbosity.
2104	- unbound-control log_reopen command.
2105	- moved get_option code from unbound-checkconf to util/config_file.c
2106
210717 February 2010: Wouter
2108	- Disregard DNSKEY from authority section for chain of trust.
2109	  DS records that are irrelevant to a referral scrubbed.  Anti-poison.
2110	- iana portlist updated.
2111
211216 February 2010: Wouter
2113	- Check for 'no space left on device' (or other errors) when
2114	  writing updated autotrust anchors and print errno to log.
2115
211615 February 2010: Wouter
2117	- Fixed the requery protection, the TTL was 0, it is now 900 seconds,
2118	  hardcoded.  We made the choice to send out more conservatively,
2119	  protecting against an aggregate effect more than protecting a
2120	  single user (from their own folly, perhaps in case of misconfig).
2121
212212 February 2010: Wouter
2123	- Re-query pattern changed on validation failure.  To protect troubled
2124	  authority servers, unbound caches a failure for the DNSKEY or DS
2125	  records for the entire zone, and only retries that 900 seconds later.
2126	  This implies that only a handful of packets are sent extra to the
2127	  authority if the zone fails.
2128
212911 February 2010: Wouter
2130	- ldns tarball update for long label length syntax error fix.
2131	- iana portlist updated.
2132
21339 February 2010: Wouter
2134	- Fixup in compat snprintf routine, %f 1.02 and %g support.
2135	- include math.h for testbound test compile portability.
2136
21372 February 2010: Wouter
2138	- Updated url of IANA itar, interim trust anchor repository, in script.
2139
21401 February 2010: Wouter
2141	- iana portlist updated.
2142	- configure test for memcmp portability.
2143
214427 January 2010: Wouter
2145	- removed warning on format string in validator error log statement.
2146	- iana portlist updated.
2147
214822 January 2010: Wouter
2149	- libtool finish the install of unbound python dynamic library.
2150
215121 January 2010: Wouter
2152	- acx_nlnetlabs.m4 synchronised with nsd's version.
2153
215420 January 2010: Wouter
2155	- Fixup lookup trouble for parent-child domains on the first query.
2156
215714 January 2010: Wouter
2158	- Fixup ldns detection to also check for header files.
2159
216013 January 2010: Wouter
2161	- prefetch-key option that performs DNSKEY queries earlier in the
2162	  validation process, and that could halve the latency on DNSSEC
2163	  queries.  It takes some extra processing (CPU, a cache is needed).
2164
216512 January 2010: Wouter
2166	- Fix unbound-checkconf for auto-trust-anchor-file present checks.
2167
21688 January 2010: Wouter
2169	- Fix for parent-child disagreement code which could have trouble
2170	  when (a) ipv6 was disabled and (b) the TTL for parent and child
2171	  were different.  There were two bugs, the parent-side information
2172	  is fixed to no longer block lookup of child side information and
2173	  the iterator is fixed to no longer attempt to get ipv6 when it is
2174	  not enabled and then give up in failure.
2175	- test and fixes to make prefetch actually store the answer in the
2176	  cache.  Considers some rrsets 'already expired' but does not allow
2177	  overwriting of rrsets considered more secure.
2178
21797 January 2010: Wouter
2180	- Fixup python documentation (thanks Leo Vandewoestijne).
2181	- Work on cache prefetch feature.
2182	- Stats for prefetch, in log print stats, unbound-control stats
2183	  and in unbound_munin plugin.
2184
21856 January 2010: Wouter
2186	- iana portlist updated.
2187	- bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.
2188	- verbose output includes parent-side-address notion for lameness.
2189	- documented val-log-level: 2 setting in example.conf and man page.
2190	- change unbound-control-setup from 1024(sha1) to 1536(sha256).
2191
21921 January 2010: Wouter
2193	- iana portlist updated.
2194
219522 December 2009: Wouter
2196	- configure with newer libtool 2.2.6b.
2197
219817 December 2009: Wouter
2199	- review comments.
2200	- tag 1.4.1.
2201	- trunk to version 1.4.2.
2202
220315 December 2009: Wouter
2204	- Answer to qclass=ANY queries, with class IN contents.
2205	  Test that validation also works.
2206	- updated ldns snapshot tarball with latest fixes (parsing records).
2207
220811 December 2009: Wouter
2209	- on IPv4 UDP turn off DF flag.
2210
221110 December 2009: Wouter
2212	- requirements.txt updated with design choice explanations.
2213	- Reading fixes: fix to set unlame when child confirms parent glue,
2214	  and fix to avoid duplicate addresses in delegation point.
2215	- verify_rrsig routine checks expiration last.
2216
22179 December 2009: Wouter
2218	- Fix Bug#287(reopened): update of ldns tarball with fix for parse
2219	  errors generated for domain names like '.example.com'.
2220	- Fix SOA excluded from negative DS responses.  Reported by Hauke
2221	  Lampe.  The negative cache did not include proper SOA records for
2222	  negative qtype DS responses which makes BIND barf on it, such
2223	  responses are now only used internally.
2224	- Fix negative cache lookup of closestencloser check of DS type bit.
2225
22268 December 2009: Wouter
2227	- Fix for lookup of parent-child disagreement domains, where the
2228	  parent-side glue works but it does not provide proper NS, A or AAAA
2229	  for itself, fixing domains such as motorcaravanners.eu.
2230	- Feature: you can specify a port number in the interface: line, so
2231	  you can bind the same interface multiple times at different ports.
2232
22337 December 2009: Wouter
2234	- Bug#287: Fix segfault when unbound-control remove nonexistent local
2235	  data.  Added check to tests.
2236
22371 December 2009: Wouter
2238	- Fix crash with module-config "iterator".
2239	- Added unit test that has "iterator" module-config.
2240
224130 November 2009: Wouter
2242	- bug#284: fix parse of # without end-of-line at end-of-file.
2243
224426 November 2009: Wouter
2245	- updated ldns with release candidate for version 1.6.3.
2246	- tag for 1.4.0 release.
2247	- 1.4.1 version in trunk.
2248	- Fixup major libtool version to 2 because of why_bogus change.
2249	  It was 1:5:0 but should have been 2:0:0.
2250
225123 November 2009: Wouter
2252	- Patch from David Hubbard for libunbound manual page.
2253	- Fixup endless spinning in unbound-control stats reported by
2254	  Attila Nagy.  Probably caused by clock reversal.
2255
225620 November 2009: Wouter
2257	- contrib/split-itar.sh contributed by Tom Hendrikx.
2258
225919 November 2009: Wouter
2260	- better argument help for unbound-control.
2261	- iana portlist updated.
2262
226317 November 2009: Wouter
2264	- noted multiple entries for multiple domain names in example.conf.
2265	- iana portlist updated.
2266
226716 November 2009: Wouter
2268	- Fixed signer detection of CNAME responses without signatures.
2269	- Fix#282 libunbound memleak on error condition by Eric Sesterhenn.
2270	- Tests for CNAMEs to deeper trust anchors, secure and bogus.
2271	- svn tag 1.4.0rc1 made.
2272
227313 November 2009: Wouter
2274	- Fixed validation failure for CNAME to optout NSEC3 nodata answer.
2275	- unbound-host does not fail on type ANY.
2276	- Fixed wireparse failure to put RRSIGs together with data in some
2277	  long ANY mix cases, which fixes validation failures.
2278
227912 November 2009: Wouter
2280	- iana portlist updated.
2281	- fix manpage errors reported by debian lintian.
2282	- review comments.
2283	- fixup very long vallog2 level error strings.
2284
228511 November 2009: Wouter
2286	- ldns tarball updated (to 1.6.2).
2287	- review comments.
2288
228910 November 2009: Wouter
2290	- Thanks to Surfnet found bug in new dnssec-retry code that failed
2291	  to combine well when combined with DLV and a particular failure.
2292	- Fixed unbound-control -h output about argument optionality.
2293	- review comments.
2294
22955 November 2009: Wouter
2296	- lint fixes and portability tests.
2297	- better error text for multiple domain keys in one autotrust file.
2298
22992 November 2009: Wouter
2300	- Fix bug where autotrust does not work when started with a DS.
2301	- Updated GOST unit tests for unofficial algorithm number 249
2302	  and DNSKEY-format changes in draft version -01.
2303
230429 October 2009: Wouter
2305	- iana portlist updated.
2306	- edns-buffer-size option, default 4096.
2307	- fixed do-udp: no.
2308
230928 October 2009: Wouter
2310	- removed abort on prealloc failure, error still printed but softfail.
2311	- iana portlist updated.
2312	- RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
2313	- ldns tarball updated (which also enables rsasha256 support).
2314
231527 October 2009: Wouter
2316	- iana portlist updated.
2317
23188 October 2009: Wouter
2319	- please doxygen
2320	- add val-log-level print to corner case (nameserver.epost.bg).
2321	- more detail to errors from insecure delegation checks.
2322	- Fix double time subtraction in negative cache reported by
2323	  Amanda Constant and Hugh Mahon.
2324	- Made new validator error string available from libunbound for
2325	  applications.  It is in result->why_bogus, a zero-terminated string.
2326	  unbound-host prints it by default if a result is bogus.
2327	  Also the errinf is public in module_qstate (for other modules).
2328
23297 October 2009: Wouter
2330	- retry for validation failure in DS and prime results. Less mem use.
2331	  unit test.  Provisioning in other tests for requeries.
2332	- retry for validation failure in DNSKEY in middle of chain of trust.
2333	  unit test.
2334	- retry for empty non terminals in chain of trust and unit test.
2335	- Fixed security bug where the signatures for NSEC3 records were not
2336	  checked when checking for absence of DS records.  This could have
2337	  enabled the substitution of an insecure delegation.
2338	- moved version number to 1.4.0 because of 1.3.4 release with only
2339	  the NSEC3 patch from the entry above.
2340	- val-log-level: 2 shows extended error information for validation
2341	  failures, but still one (longish) line per failure.  For example:
2342	  validation failure <example.com. DNSKEY IN>: signature expired from
2343	  192.0.2.4 for trust anchor example.com. while building chain of trust
2344	  validation failure <www.example.com. A IN>: no signatures from
2345	  192.0.2.6 for key example.com. while building chain of trust
2346
23476 October 2009: Wouter
2348	- Test set updated to provide additional ns lookup result.
2349	  The retry would attempt to fetch the data from other nameservers
2350	  for bogus data, and this needed to be provisioned in the tests.
2351
23525 October 2009: Wouter
2353	- first validation failure retry code.  Retries for data failures.
2354	  And unit test.
2355
23562 October 2009: Wouter
2357	- improve 5011 modularization.
2358	- fix unbound-host so -d can be given before -C.
2359	- iana portlist updated.

2376	- test unbound reading of original autotrust data.
2377	  The metadata per-key, such as key state (PENDING, MISSING, VALID) is
2378	  picked up, otherwise performs initial probe like usual.

238022 September 2009: Wouter
2381	- autotrust test with algorithm rollover, new ordering of checks
2382	  assists in orderly rollover.

2407	- increased MAXSYSLOGLEN so .bg key can be printed in debug output.
2408	- use linebuffering for log-file: output, this can be significantly
2409	  faster than the previous fflush method and enable some class of
2410	  resolvers to use high verbosity (for short periods).
2411	  Not on windows, because line buffering does not work there.
2412
24139 September 2009: Wouter
2414	- Fix bug where DNSSEC-bogus messages were marked with too high TTL.
2415	  The RRsets would still expire at the normal time, but this would

2634	  structures so that later validation would fail.
2635	- Extreme lenience for wrongly truncated replies where a positive
2636	  reply has an NS in the authority but no signatures.  They are
2637	  turned into minimal responses with only the (secure) answer.
2638	- autoconf 2.63 for configure.
2639	- python warnings suppress.  Keep python API away from header files.

2647	  generate queries that are known to fail.
2648	- Touchup on munin total memory report.
2649	- messages picked out of the cache by the iterator are checked
2650	  if their cname chain is still correct and if validation status
2651	  has to be reexamined.
2652
265315 June 2009: Wouter
2654	- iana portlist updated.
2655
265614 June 2009: Wouter

2668	- fwd above stub in configuration works.
2669
267011 June 2009: Wouter
2671	- Fix queries for type DS when forward or stub zones are there.
2672	  They are performed to higherup domains, and thus treated as if
2673	  going to higher zones when looking up the right forward or stub
2674	  server.  This makes a stub pointing to a local server that has
2675	  a local view of example.com signed with the same keys as are
2676	  publicly used work.  Reported by Johan Ihren.
2677	- Added build-unbound-localzone-from-hosts.pl to contrib, from
2678	  Dennis DeDonatis.  It converts /etc/hosts into config statements.
2679	- same thing fixed for forward-zone and DS, chain of trust from
2680	  public internet into the forward-zone works now.  Added unit test.
2681
26829 June 2009: Wouter
2683	- openssl key files are opened apache-style, when user is root and
2684	  before chrooting.  This makes permissions on remote-control key
2685	  files easier to set up.  Fixes bug #251.
2686	- flush_type and flush_name remove msg cache entries.
2687	- codereview - dp copy bogus setting fix.
2688
26898 June 2009: Wouter
2690	- Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
2691	  inadvertant behaviour.
2692	- 1.3.0 tarball for release created.
2693	- 1.3.1 development in svn trunk.

2702	  Reported by Paul Wouters.
2703	- review comments from Matthijs.
2704
27052 June 2009: Wouter
2706	- --enable-sha2 option. The draft rsasha256 changed its algorithm
2707	  numbers too often.  Therefore it is more prudent to disable the
2708	  RSASHA256 and RSASHA512 support by default.
2709	- ldns trunk included as new tarball.
2710	- recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.

2718
271927 May 2009: Wouter
2720	- detect lack of IPv6 support on XP (with a different error code).
2721	- Fixup a crash-on-exit which was triggered by a very long queue.
2722	  Unbound would try to re-use ports that came free, but this is
2723	  of course not really possible because everything is deleted.
2724	  Most easily triggered on XP (not Vista), maybe because of the
2725	  network stack encouraging large messages backlogs.
2726	- change in debug statements.
2727	- Fixed bug that could cause a crash if root prime failed when there
2728	  were message backlogs.
2729
273026 May 2009: Wouter
2731	- Thanks again to Brett Carr, found an assertion that was not true.
2732	  Assertion checked if recursion parent query still existed.
2733
273429 April 2009: Wouter
2735	- Thanks to Brett Carr, caught windows resource leak, use
2736	  closesocket() and not close() on sockets or else the network stack
2737	  starts to leak handles.
2738	- Removed usage of windows Mutex because windows cannot handle enough
2739	  mutexes open.  Provide own mutex implementation using primitives.
2740
274128 April 2009: Wouter
2742	- created svn tag for 1.3.0.

2784	- ldns tarball updated.
2785	- iana portlist update.
2786	- detect GOST support in openssl-1.0.0-beta1, and fix compile problem
2787	  because that openssl defines the name STRING for itself.
2788
27896 April 2009: Wouter
2790	- windows compile fix.
2791	- Detect FreeBSD jail without ipv6 addresses assigned.
2792	- python libunbound wrapper unit test.
2793	- installs the following files. Default is to not build them.

2795	  /usr/lib/python2.x/site-packages/unboundmodule.py
2796	  	from configure --with-pyunbound:
2797	  /usr/lib/python2.x/site-packages/unbound.py
2798	  /usr/lib/python2.x/site-packages/_unbound.so*
2799	  The example python scripts (pythonmod/examples and

2804
28053 April 2009: Wouter
2806	- Fixed a bug that caused messages to be stored in the cache too
2807	  long.  Hard to trigger, but NXDOMAINs for nameservers or CNAME
2808	  targets have been more vulnerable to the TTL miscalculation bug.
2809	- documentation test fixed for python addition.
2810
28112 April 2009: Wouter
2812	- pyunbound (libunbound python plugin) compiles using libtool.
2813	- documentation for pythonmod and pyunbound is generated in doc/html.
2814	- iana portlist updated.
2815	- fixed bug in unbound-control flush_zone where it would not flush
2816	  every message in the target domain.  This especially impacted
2817	  NXDOMAIN messages which could remain in the cache regardless.
2818	- python module test package.
2819
28201 April 2009: Wouter
2821	- suppress errors when trying to contact authority servers that gave
2822	  ipv6 AAAA records for their nameservers with ipv4 mapped contents.
2823	  Still tries to do so, could work when deployed in intranet.

2879	- Added tests, unknown algorithms become insecure. fallback works.
2880	- Fix for and test for unknown algorithms in a trust anchor
2881	  definition.  Trust anchors with no supported algos are ignored.
2882	  This means a (higher)DS or DLV entry for them could succeed, and
2883	  otherwise they are treated as insecure.
2884	- domain-insecure: "example.com" statement added. Sets domain

2967	- unbound-checkconf and unbound print warnings when trust anchors
2968	  have unsupported algorithms.
2969	- added contrib/update-itar.sh  This script is similar to
2970	  update-anchor.sh, and updates from the IANA ITAR repository.
2971	  You can provide your own PGP key and trust repo, or can use the
2972	  builtin.  The program uses wget and gpg to work.
2973	- iana portlist updated.
2974	- update-itar.sh: using ftp:// urls because https godaddy certificate
2975	  is not available everywhere and then gives fatal errors.  The

297818 February 2009: Wouter
2979	- more cycle detection. Also for target queries.
2980	- fixup bug where during deletion of the mesh queries the callbacks

2982	  a reentrant safe state.  Affects libunbound, reload of server,
2983	  on quit and flush_requestlist.
2984	- iana portlist updated.
2985
298613 February 2009: Wouter
2987	- forwarder information now per-thread duplicated.
2988	  This keeps it read only for speed, with no locking necessary.

2991	- document that unbound-host reads no config file by default.
2992	- updated iana portlist.
2993

3013	- fixup EOL in include directive (reported by Paul Wouters).
3014	  You can no longer specify newlines in the names of included files.
3015	- config parser changed. Gives some syntax errors closer to where they
3016	  occurred. Does not enforce a space after keyword anymore.
3017	  Does not allow literal newlines inside quoted strings anymore.
3018	- verbosity level 5 logs customer IP for new requestlist entries.
3019	- test fix, lexer and cancel test.
3020	- new option log-time-ascii: yes  if you enable it prints timestamps
3021	  in the log file as Feb 06 13:45:26 (like syslog does).
3022	- detect event_base_new in libevent-1.4.1 and later and use it.
3023	- #231 unbound-checkconf -o option prints that value from config file.
3024	  Useful for scripting in management scripts and the like.
3025
30265 February 2009: Wouter
3027	- ldns 1.5.0 rc as tarball included.
3028	- 1.3.0 development continues:
3029	  change in libunbound API: ub_cancel can return an error, that
3030	  the async_id did not exist, or that it was already delivered.
3031	  The result could have been delivered just before the cancel
3032	  routine managed to acquire the lock, so a caller may get the
3033	  result at the same time they call cancel.  For this case,
3034	  ub_cancel tries to return an error code.
3035	  Fixes race condition in ub_cancel() libunbound function.
3036	- MacOSX Leopard cleaner text output from configure.
3037	- initgroups(3) is called to drop secondary group permissions, if
3038	  applicable.
3039	- configure option --with-ldns-builtin forces the use of the
3040	  inluded ldns package with the unbound source.  The -I include
3041	  is put before the others, so it avoids bad include files from
3042	  an older ldns install.
3043	- daemon(3) posix call is used when available.
3044	- testbound test for older fix added.
3045
30464 February 2009: Wouter
3047	- tag for release 1.2.1.
3048	- trunk setup for 1.3.0 development.
3049
30503 February 2009: Wouter
3051	- noted feature requests in doc/TODO.
3052	- printout more detailed errors on ssl certificate loading failures.
3053	- updated IANA portlist.
3054
305516 January 2009: Wouter
3056	- more quiet about ipv6 network failures, i.e. when ipv6 is not
3057	  available (network unreachable). Debug still printed on high
3058	  verbosity.
3059	- unbound-host -4 and -6 options. Stops annoying ipv6 errors when
3060	  debugging with unbound-host -4 -d ...
3061	- more cycle detection for NS-check, addr-check, root-prime and
3062	  stub-prime queries in the iterator.  Avoids possible deadlock
3063	  when priming fails.
3064
306515 January 2009: Wouter
3066	- bug #229: fixup configure checks for compilation with Solaris
3067	  Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc

3069	- fix bug where unbound could crash using libevent 1.3 and older.
3070	- update testset for recent retry change.
3071
307214 January 2009: Wouter
3073	- 1.2.1 feature: negative caching for failed queries.
3074	  Queries that failed are cached for 5 seconds (NORR_TTL).
3075	  If the failure is local, like out of memory, it is not cached.
3076	- the TTL comparison for the cache used different comparisons,
3077	  causing many cache responses that used the iterator and validator
3078	  state machines unnecessarily.
3079	- retry from 4 to 5 so that EDNS drop retry is part of the first
3080	  query resolve attempt, and cached error does not stop EDNS fallback.
3081	- remove debug prints that protect against bad referrals.
3082	- honor QUIET=no on make commandline (or QUIET=yes ).
3083
308413 January 2009: Wouter
3085	- fixed bug in lameness marking, removed printouts.
3086	- find NS rrset more cleanly for qtype NS.
3087	- Moved changes to 1.2.0 for release. Thanks to Mark Zealey for
3088	  reporting and logs.

3090	  are in the negative cache.
3091
309212 January 2009: Wouter
3093	- fixed bug in infrastructure lameness cache, did not lowercase
3094	  name of zone to hash when setting lame.

3106	- remove possible race condition in the test for race conditions.
3107
31087 January 2009: Wouter
3109	- version 1.2.0 in preparation.
3110	- feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
3111	  statements. (Adapted from patch by Paul Wouters).
3112	- typo fix and iana portlist updated.
3113	- porting testsuite; unused var warning, and type fixup.
3114
31156 January 2009: Wouter
3116	- fixup packet-of-death when compiled with --enable-debug.
3117	  A malformed packet could cause an internal assertion failure.
3118	- added test for HINFO canonicalisation behaviour.
3119	- fixup reported problem with transparent local-zone data where
3120	  queries with different type could get nxdomain. Now queries
3121	  with a different name get resolved normally, with different type
3122	  get a correct NOERROR/NODATA answer.
3123	- HINFO no longer downcased for validation, making unbound compatible
3124	  with bind and ldns.
3125	- fix reading included config files when chrooted.
3126	  Give full path names for include files.
3127	  Relative path names work if the start dir equals the working dir.
3128	- fix libunbound message transport when no packet buffer is available.
3129
31305 January 2009: Wouter
3131	- fixup getaddrinfo failure handling for remote control port.

3133	- fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
3134	- comm_timer_set performs base_set operation after event_add.
3135
313618 December 2008: Wouter
3137	- fixed bug reported by Duane Wessels: error in DLV lookup, would make
3138	  some zones that had correct DLV keys as insecure.
3139	- follows -rc makedist from ldns changes (no _rc).
3140	- ldns tarball updated with 1.4.1rc for DLV unit test.
3141	- verbose prints about recursion lame detection and server selection.
3142	- fixup BSD port for infra host storage. It hashed wrongly.
3143	- fixup makedist snapshot name generation.
3144	- do not reopen syslog to avoid dev/log dependency.
3145
314617 December 2008: Wouter
3147	- follows ldns makedist.sh. -rc option. autom4te dir removed.
3148	- unbound-control status command.
3149	- extended statistics has a number of ipv6 queries counter.
3150	  contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
3151
315216 December 2008: Wouter
3153	- follow makedist improvements from ldns, for maintainers prereleases.
3154	- snapshot version uses _ not - to help rpm distinguish the
3155	  version number.
3156

3158	- better fix for bug #219: use LOG_NDELAY with openlog() call.
3159	  Thanks to Tamas Tevesz.
3160
31619 December 2008: Wouter

3164	- iana portlist updated.
3165
31663 December 2008: Wouter
3167	- Fix problem reported by Jaco Engelbrecht where unbound-control stats
3168	  freezes up unbound if this was compiled without threading, and
3169	  was using multiple processes.
3170	- iana portlist updated.
3171	- test for remote control with interprocess communication.
3172	- created command distribution mechanism so that remote control
3173	  commands other than 'stats' work on all processes in a nonthreaded
3174	  compiled version. dump/load cache work, on the first process.
3175	- fixup remote control local_data addition memory corruption bug.
3176
31771 December 2008: Wouter
3178	- SElinux policy files in contrib/selinux for the unbound daemon,
3179	  by Paul Wouters and Adam Tkac.
3180
318125 November 2008: Wouter
3182	- configure complains when --without-ssl is given (bug #220).
3183	- skip unsupported feature tests on vista/mingw.
3184	- fixup testcode/streamtcp to work on vista/mingw.
3185	- root-hints test checks version of dig required.
3186	- blacklisted servers are polled at a low rate (1%) to see if they
3187	  come back up. But not if there is some other working server.
3188
318924 November 2008: Wouter
3190	- document that the user of the server daemon needs read privileges
3191	  on the keys and certificates generated by unbound-control-setup.
3192	  This is different per system or distribution, usually, running the
3193	  script under the same username as the server uses suffices.
3194	  i.e.  sudo -u unbound unbound-control-setup
3195	- testset port to vista/mingw.
3196	- tcp_sigpipe to freebsd port.
3197
319821 November 2008: Wouter
3199	- fixed tcp accept, errors were printed when they should not.
3200	- unbound-control-setup.sh removes read/write permissions other

3204	- fixup fatal error due to faulty error checking after tcp accept.
3205	- add check in rlimit to avoid integer underflow.
3206	- rlimit check with new formula; better estimate for number interfaces
3207	- nicer comments in rlimit check.

3210
321119 November 2008: Wouter

3221
322217 November 2008: Wouter
3223	- theoretical fix for problems reported on mailing list.
3224	  If a delegation point has no A but only AAAA and do-ip6 is no,
3225	  resolution would fail. Fixed to ask for the A and AAAA records.
3226	  It has to ask for both always, so that it can fail quietly, from
3227	  TLD perspective, when a zone is only reachable on one transport.
3228	- test for above, only AAAA and doip6 is no. Fix causes A record
3229	  for nameserver to be fetched.
3230	- fixup address duplication on cache fillup for delegation points.
3231	- testset updated for new query answer requirements.
3232

3269	- dname_priv must decompress the name before comparison.
3270	- iana portlist updated.
3271
32725 November 2008: Wouter
3273	- fixed possible memory leak in key_entry_key deletion.
3274	  Would leak a couple bytes when trust anchors were replaced.
3275	- if query and reply qname overlap, the bytes are skipped not copied.
3276	- fixed file descriptor leak when messages were jostled out that
3277	  had outstanding (TCP) replies.
3278	- DNAMEs used from cache have their synthesized CNAMEs initialized
3279	  properly.
3280	- fixed file descriptor leak for localzone type deny (for TCP).
3281	- fixed memleak at exit for nsec3 negative cached zones.
3282	- fixed memleak for the keyword 'nodefault' when reading config.
3283	- made verbosity of 'edns incapable peer' warning higher, so you
3284	  do not get spammed by it.
3285	- caught elusive Bad file descriptor error bug, that would print the
3286	  error while unnecessarily try to listen to a closed fd. Fixed.
3287
32884 November 2008: Wouter
3289	- fixed -Wwrite-strings warnings that result in better code.
3290
32913 November 2008: Wouter
3292	- fixup build process for Mac OSX linker, use ldns b32 compat funcs.
3293	- generated configure with autoconf-2.61.
3294	- iana portlist updated.
3295	- detect if libssl needs libdl.  For static linking with libssl.
3296	- changed to use new algorithm identifiers for sha256/sha512
3297	  from ldns 1.4.0 (need very latest version).
3298	- updated the included ldns tarball.
3299	- proper detection of SHA256 and SHA512 functions (not just sizes).
3300
330123 October 2008: Wouter
3302	- a little more debug info for failure on signer names. prints names.
3303
330422 October 2008: Wouter
3305	- CFLAGS are picked up by configure from the environment.
3306	- iana portlist updated.
3307	- updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
3308	- new stub-prime: yesno option. Default is off, so it does not prime.
3309	  can be turned on to get same behaviour as previous unbound release.
3310	- made automated test that checks if builtin root hints are uptodate.
3311	- finished draft-wijngaards-dnsext-resolver-side-mitigation
3312	  implementation. The unwanted-reply-threshold can be set.
3313	- fixup so fptr_whitelist test in alloc.c works.
3314
331521 October 2008: Wouter
3316	- fix update-anchors.sh, so it does not report different RR order
3317	  as an update.  Sorts the keys in the file.  Updated copyright.
3318	- fixup testbound on windows, the command control pipe doesn't exist.
3319	- skip 08hostlib test on windows, no fork() available.
3320	- made unbound-remote work on windows.
3321
332220 October 2008: Wouter
3323	- quench a log message that is debug only.
3324	- iana portlist updated.
3325	- do not query bogus nameservers.  It is like nameservers that have
3326	  the NS or A or AAAA record bogus are listed as donotquery.
3327	- if server selection is faced with only bad choices, it will
3328	  attempt to get more options to be fetched.
3329	- changed bogus-ttl default value from 900 to 60 seconds.
3330	  In anticipation that operator caused failures are more likely than
3331	  actual attacks at this time.  And thus repeated validation helps
3332	  the operators get the problem fixed sooner.  It makes validation
3333	  failures go away sooner (60 seconds after the zone is fixed).
3334	  Also it is likely to try different nameserver targets every minute,
3335	  so that if a zone is bad on one server but not another, it is
3336	  likely to pick up the 'correct' one after a couple minutes,
3337	  and if the TTL is big enough that solves validation for the zone.
3338	- fixup unbound-control compilation on windows.
3339
334017 October 2008: Wouter
3341	- port Leopard/G5: fixup type conversion size_t/uint32.
3342	  please ranlib, stop file without symbols warning.
3343	- harden referral path now also validates the root after priming.
3344	  It looks up the root NS authoritatively as well as the root servers
3345	  and attemps to validate the entries.
3346
334716 October 2008: Wouter
3348	- Fixup negative TTL values appearing (reported by Attila Nagy).
3349
335015 October 2008: Wouter
3351	- better documentation for 0x20; remove fallback TODO, it is done.
3352	- harden-referral-path feature includes A, AAAA queries for glue,
3353	  as well as very careful NS caching (only when doing NS query).
3354	  A, AAAA use the delegation from the NS-query.
3355
335614 October 2008: Wouter
3357	- fwd_three.tpkg test was flaky.  If the three requests hit the
3358	  wrong threads by chance (or bad OS) then the test would fail.
3359	  Made less flaky by increasing number of retries.
3360	- stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
3361	- ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
3362	  Which includes the ldns_dname_absolute fix.
3363	- fwd_three test remains flaky now that unbound does not stop
3364	  listening when full.  Thus, removed timeout problem.
3365	  It may be serviced by three threads, or maybe by one.
3366	  Mostly only useful for lock-check testing now.
3367
336813 October 2008: Wouter
3369	- fixed recursion servers deployed as authoritative detection, so
3370	  that as a last resort, a +RD query is sent there to get the
3371	  correct answer.
3372	- iana port list update.
3373	- ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
3374
337510 October 2008: Wouter
3376	- fixup tests - the negative cache contained the correct NSEC3s for
3377	  two tests that are supposed to fail to validate.
3378
33799 October 2008: Wouter
3380	- negative cache caps max iterations of NSEC3 done.
3381	- NSEC3 negative cache for qtype DS works.
3382
33838 October 2008: Wouter
3384	- NSEC negative cache for DS.
3385
33866 October 2008: Wouter
3387	- jostle-timeout option, so you can config for slow links.
3388	- 0x20 fallback code.  Tries 3xnumber of nameserver addresses
3389	  queries that must all be the same.  Sent to random nameservers.
3390	- documented choices for DoS, EDNS, 0x20.
3391
33922 October 2008: Wouter
3393	- fixup unlink of pidfile.
3394	- fixup SHA256 algorithm collation code.
3395	- contrib/update-anchor.sh does not overwrite anchors if not needed.
3396	  exits 0 when a restart is needed, other values if not.
3397	  so,  update-anchor.sh -d mydir && /etc/rc.d/unbound restart
3398	  can restart unbound exactly when needed.
3399
340030 September 2008: Wouter
3401	- fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
3402	- tests for sha256 support and downgrade resistance.
3403	- RSASHA256 and RSASHA512 support (using the draft in dnsext),
3404	  using the drafted protocol numbers.
3405	- when using stub on localhost (127.0.0.1@10053) unbound works.
3406	  Like when running NSD to host a local zone, on the same machine.
3407	  The noprime feature. manpages more explanation. Added a test for it.
3408	- shorthand for reverse PTR,  local-data-ptr: "1.2.3.4 www.ex.com"
3409
341029 September 2008: Wouter
3411	- EDNS lameness detection, if EDNS packets are dropped this is
3412	  detected, eventually.
3413	- multiple query timeout rtt backoff does not backoff too much.
3414

3463	- removed browser control mentions. Proto speccy.
3464
346511 September 2008: Wouter

3493	  is removed too.
3494
34951 September 2008: Wouter
3496	- disallow nonrecursive queries for cache snooping by default.
3497	  You can allow is using access-control: <subnet> allow_snoop.
3498	  The defaults do allow access no authoritative data without RD bit.
3499	- two tests for it and fixups of tests for nonrec refused.
3500
350129 August 2008: Wouter
3502	- version 1.1 number in trunk.
3503	- harden-referral-path option for query for NS records.
3504	  Default turns off expensive, experimental option.
3505
350628 August 2008: Wouter
3507	- fixup logfile handling; it is created with correct permissions
3508	  again. (from bugfix#199).
3509	  Some errors are not written to logfile (pidfile writing, forking),
3510	  and these are only visible by using the -d commandline flag.
3511
351227 August 2008: Wouter
3513	- daemon(3) is causing problems for people. Reverting the patch.
3514	  bug#200, and 199 and 203 contain sideline discussion on it.
3515	- bug#199 fixed: pidfile can be outside chroot. openlog is done before
3516	  chroot and drop permissions.
3517	- config option to set size of aggressive negative cache,
3518	  neg-cache-size.
3519	- bug#203 fixed: dlv has been implemented.

3572	- finished adjusting testset to provide qtype NS answers.
3573
357411 August 2008: Wouter
3575	- Fixup rrset security updates overwriting 2181 trust status.
3576	  This makes validated to be insecure data just as worthless as
3577	  nonvalidated data, and 2181 rules prevent cache overwrites to them.
3578	- Fix assertion fail on bogus key handling.
3579	- dnssec lameness detection works on first query at trust apex.
3580	- NS queries get proper cache and dnssec lameness treatment.

3607	- created tube signaling solution on windows, as a pipe replacement.
3608	  this makes background asynchronous resolution work on windows.
3609	- removed very insecure socketpair compat code. It also did not
3610	  work with event_waiting. Solved by pipe replacement.
3611	- unbound -h prints openssl version number as well.
3612
361322 July 2008: Wouter

3632	  fds than the builtin minievent can handle.
3633
363416 July 2008: Wouter
3635	- made svn tag 1.0.1, trunk now 1.0.2
3636	- sha256 checksums enabled in makedist.sh

3657	- fixup unit test for infra cache, test lame merging.
3658	- porting to mingw, bind, listen, getsockopt and setsockopt error
3659	  handling.
3660
366124 June 2008: Wouter
3662	- removed testcode/checklocks from production code compilation path.
3663	- streamtcp can use UDP mode (connected UDP socket), for testing IPv6
3664	  on windows.
3665	- fwd_ancil test fails if platform support is lacking.
3666
366723 June 2008: Wouter
3668	- fixup minitpkg to cleanup on windows with its file locking troubles.
3669	- minitpkg shows skipped tests in report.
3670	- skip ipv6 tests on ipv4 only hosts (requires only ipv6 localhost not
3671	  ipv6 connectivity).
3672	- winsock event handler keeps track of sticky TCP events, that have
3673	  not been fully handled yet. when interest in the event(s) resumes,
3674	  they are sent again. When WOULDBLOCK is returned events are cleared.
3675	- skip tests that need signals when testing on mingw.
3676
367718 June 2008: Wouter
3678	- open testbound replay files in binary mode, because fseek/ftell
3679	  do not work in ascii-mode on windows. The b does nothing on unix.
3680	  unittest and testbound tests work on windows (xp too).
3681	- ioctlsocket prints nicer error message.
3682	- fixed up some TCP porting for winsock.
3683	- lack of IPv6 gives a warning, no fatal error.
3684	- use WSAGetLastError() on windows instead of errno for some errors.
3685
368617 June 2008: Wouter
3687	- outgoing num fds 32 by default on windows ; it supports less
3688	  fds for waiting on than unixes.
3689	- winsock_event minievent handler for windows. (you could also
3690	  attempt to link with libevent/libev ports for windows).
3691	- neater crypto check and gdi32 detection.
3692	- unbound.exe works to resolve and validate www.nlnetlabs.nl on vista.
3693
369416 June 2008: Wouter
3695	- on windows, use windows threads, mutex and thread-local-storage(Tls).
3696	- detect if openssl needs gdi32.
3697	- if no threading, THREADS_DISABLED is defined for use in the code.
3698	- sets USE_WINSOCK if using ws2_32 on windows.
3699	- wsa_strerror() function for more readable errors.
3700	- WSA Startup and Cleanup called in unbound.exe.
3701
370213 June 2008: Wouter

37109 June 2008: Wouter
3711	- in iteration response type code
3712	  * first check for SOA record (negative answer) before NS record
3713	    and lameness.

3749	  - bug 179: same fix as 177.
3750	  - bug 185: --disable-shared not passed along to ldns included with
3751	    unbound. Fixed so that configure parameters are passed to the
3752	    subdir configure script.
3753	    fixed that ./libtool is used always, you can still override
3754	    manually with ./configure libtool=mylibtool or set $libtool in
3755	    the environment.
3756	- update of the ldns tarball to current ldns svn version (fix 181).
3757	- bug 184: -r option for unbound-host, read resolv.conf for

3772	  - if no kill() then no pidfile is read or written.
3773	  - gmtime_r is replaced by nonthreadsafe alternative if unavail.
3774	    used in rrsig time validation errors.
3775

3851	- got update for parseunbound.pl statistics script from Kai Storbeck.
3852	- tpkg tests for udp wait list.
3853	- documented 0x20 status.
3854	- fixup chroot and checkconf, it is much smarter now.

385811 April 2008: Wouter
3859	- random port selection out of the configged ports.
3860	- fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
3861	- removed base_port.
3862	- created 256-port ephemeral space for the OS, 59802 available.
3863	- fixup consistency of port_if out array during heavy use.
3864
386510 April 2008: Wouter
3866	- --with-libevent works with latest libevent 1.4.99-trunk.
3867	- added log file statistics perl script to contrib.
3868	- automatic iana ports update from makefile. 60058 available.
3869
38709 April 2008: Wouter
3871	- configure can detect libev(from its build directory) when passed
3872	  --with-libevent=/home/wouter/libev-3.2
3873	  libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
3874	- unused commpoints not listed in epoll list.
3875	- statistics-cumulative option so that the values are not reset.
3876	- config creates array of available ports, 61841 available,
3877	  it excludes <1024 and iana assigned numbers.
3878	  config statements to modify the available port numbers.
3879
38808 April 2008: Wouter
3881	- unbound tries to set the ulimit fds when started as server.
3882	  if that does not work, it will scale back its requirements.
3883
388427 March 2008: Wouter
3885	- documented /dev/random symlink from chrootdir as FAQ entry.
3886
388726 March 2008: Wouter
3888	- implemented AD bit signaling. If a query sets AD bit (but not DO)
3889	  then the AD bit is set in the reply if the answer validated.
3890	  Without including DNSSEC signatures. Useful if you have a trusted
3891	  path from the client to the resolver. Follows dnssec-updates draft.
3892
389325 March 2008: Wouter
3894	- implemented check that for NXDOMAIN and NOERROR answers a query
3895	  section must be present in the reply (by the scrubber). And it must
3896	  be equal to the question sent, at least lowercase folded.
3897	  Previously this feature happened because the cache code refused
3898	  to store such messages. However blocking by the scrubber makes
3899	  sure nothing gets into the RRset cache. Also, this looks like a
3900	  timeout (instead of an allocation failure) and this retries are
3901	  done (which is useful in a spoofing situation).
3902	- RTT banding. Band size 400 msec, this makes band around zero (fast)
3903	  include unknown servers. This makes unbound explore unknown servers.
3904
39057 March 2008: Wouter
3906	- -C config feature for harvest program.
3907	- harvest handles CNAMEs too.
3908
39095 March 2008: Wouter
3910	- patch from Hugo Koji Kobayashi for iterator logs spelling.
3911
39124 March 2008: Wouter
3913	- From report by Jinmei Tatuya, rfc2181 trust value for remainder
3914	  of a cname trust chain is lower; not full answer_AA.
3915	- test for this fix.
3916	- default config file location is /usr/local/etc/unbound.
3917	  Thus prefix is used to determine the location. This is also the
3918	  chroot and pidfile default location.
3919
39203 March 2008: Wouter
3921	- Create 0.10 svn tag.
3922	- 0.11 version in trunk.
3923	- indentation nicer.
3924
392529 February 2008: Wouter
3926	- documentation update.
3927	- fixup port to Solaris of perf test tool.
3928	- updated ldns-tarball with decl-after-statement fixes.
3929
393028 February 2008: Wouter
3931	- fixed memory leaks in libunbound (during cancellation and wait).
3932	- libunbound returns the answer packet in full.
3933	- snprintf compat update.
3934	- harvest performs lookup.
3935	- ldns-tarball update with fix for ldns_dname_label.
3936	- installs to sbin by default.
3937	- install all manual pages (unbound-host and libunbound too).
3938
393927 February 2008: Wouter
3940	- option to use caps for id randomness.
3941	- config file option use-caps-for-id: yes
3942	- harvest debug tool
3943
394426 February 2008: Wouter
3945	- delay utility delays TCP as well. If the server that is forwarded
3946	  to has a TCP error, the delay utility closes the connection.
3947	- delay does REUSE_ADDR, and can handle a server that closes its end.
3948	- answers use casing from query.
3949
395025 February 2008: Wouter
3951	- delay utility works. Gets decent thoughput too (>20000).
3952
395322 February 2008: Wouter
3954	- +2% for recursions, if identical queries (except for destination
3955	  and query ID) in the reply list, avoid re-encoding the answer.
3956	- removed TODO items for optimizations that do not show up in
3957	  profile reports.
3958	- default is now minievent - not libevent. As its faster and
3959	  not needed for regular installs, only for very large port ranges.
3960	- loop check different speedup pkt-dname-reading, 1% faster for
3961	  nocache-recursion check.
3962	- less hashing during msg parse, 4% for recursion.
3963	- small speed fix for dname_count_size_labels, +1 or +2% recursion.
3964	- some speed results noted:
3965	  optimization resulted in +40% for recursion (cache miss) and
3966	  +70 to +80 for cache hits, and +96% for version.bind.
3967	  zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
3968	  www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
3969	  www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
3970	  So, unbound can be about equal qps to NSD in cache hits.
3971	  And about 3.4x faster than BIND in cache performance.
3972	- delay utility for testing.
3973
397421 February 2008: Wouter
3975	- speedup of root-delegation message encoding by 15%.
3976	- minor speedup of compress tree_lookup, maybe 1%.
3977	- speedup of dname_lab_cmp and memlowercmp - the top functions in
3978	  profiler output, maybe a couple percent when it matters.
3979
398020 February 2008: Wouter
3981	- setup speec_cache for need-ldns-testns in dotests.
3982	- check number of queued replies on incoming queries to avoid overload
3983	  on that account.
3984	- fptr whitelist checks are not disabled in optimize mode.
3985	- do-daemonize config file option.
3986	- minievent time share initializes time at start.
3987	- updated testdata for nsec3 new algorithm numbers (6, 7).
3988	- small performance test of packet encoding (root delegation).
3989
399019 February 2008: Wouter
3991	- applied patch to unbound-host man page from Jan-Piet Mens.
3992	- fix donotquery-localhost: yes default (it erroneously was switched
3993	  to default 'no').
3994	- time is only gotten once and the value is shared across unbound.
3995	- unittest cleans up crypto, so that it has no memory leaks.
3996	- mini_event shares the time value with unbound this results in
3997	  +3% speed for cache responses and +9% for recursions.
3998	- ldns tarball update with new NSEC3 sign code numbers.
3999	- perform several reads per UDP operation. This improves performance
4000	  in DoS conditions, and costs very little in normal conditions.
4001	  improves cache response +50%, and recursions +10%.
4002	- modified asynclook test. because the callback from async is not
4003	  in any sort of lock (and thus can use all library functions freely),
4004	  this causes a tiny race condition window when the last lock is
4005	  released for a callback and a new cancel() for that callback.
4006	  The only way to remove this is by putting callbacks into some
4007	  lock window. I'd rather have the small possibility of a callback
4008	  for a cancelled function then no use of library functions in
4009	  callbacks. Could be possible to only outlaw process(), wait(),
4010	  cancel() from callbacks, by adding another lock, but I'd rather not.
4011
401218 February 2008: Wouter
4013	- patch to unbound-host from Jan-Piet Mens.
4014	- unbound host prints errors if fails to configure context.
4015	- fixup perf to resend faster, so that long waiting requests do
4016	  not hold up the queue, they become lost packets or SERVFAILs,
4017	  or can be sent a little while later (i.e. processing time may
4018	  take long, but throughput has to be high).
4019	- fixup iterator operating in no cache conditions (RD flag unset
4020	  after a CNAME).
4021	- streamlined code for RD flag setting.
4022	- profiled code and changed dname compares to be faster.
4023	  The speedup is about +3% to +8% (depending on the test).
4024	- minievent tests for eintr and eagain.
4025
402615 February 2008: Wouter
4027	- added FreeBSD rc.d script to contrib.
4028	- --prefix option for configure also changes directory: pidfile:
4029	  and chroot: defaults in config file.
4030	- added cache speed test, for cache size OK and cache too small.
4031
403214 February 2008: Wouter
4033	- start without a config file (will complain, but start with
4034	  defaults).
4035	- perf test program works.
4036
403713 February 2008: Wouter
4038	- 0.9 released.
4039	- 1.0 development. Printout ldns version on unbound -h.
4040	- start of perf tool.
4041	- bugfix to read empty lines from /etc/hosts.
4042
404312 February 2008: Wouter
4044	- fixup problem with configure calling itself if ldns-src tarball
4045	  is not present.
4046
404711 February 2008: Wouter
4048	- changed library to use ub_ instead of ub_val_ as prefix.
4049	- statistics output text nice.
4050	- etc/hosts handling.
4051	- library function to put logging to a stream.
4052	- set any option interface.
4053
40548 February 2008: Wouter
4055	- test program for multiple queries over a TCP channel.
4056	- tpkg test for stream tcp queries.
4057	- unbound replies to multiple TCP queries on a TCP channel.
4058	- fixup misclassification of root referral with NS in answer
4059	  when validating a nonrec query.
4060	- tag 0.9
4061	- layout of manpages, spelling fix in header, manpages process by
4062	  makedist, list asynclook and tcpstream tests as ldns-testns
4063	  required.
4064
40657 February 2008: Wouter
4066	- moved up all current level 2 to be level 3. And 3 to 4.
4067	  to make room for new debug level 2 for detailed information
4068	  for operators.
4069	- verbosity level 2. Describes recursion and validation.
4070	- cleaner configure script and fixes for libevent solaris.
4071	- signedness for log output memory sizes in high verbosity.
4072
40736 February 2008: Wouter
4074	- clearer explanation of threading configure options.
4075	- fixup asynclook test for nothreading (it creates only one process
4076	  to do the extended test).
4077	- changed name of ub_val_result_free to ub_val_resolve_free.
4078	- removes warning message during library linking, renamed
4079	  libunbound/unbound.c -> libunbound.c and worker to libworker.
4080	- fallback without EDNS if result is NOTIMPL as well as on FORMERR.
4081
40825 February 2008: Wouter
4083	- statistics-interval: seconds option added.
4084	- test for statistics option
4085	- ignore errors making directories, these can occur in parallel builds
4086	- fixup Makefile strip command and libunbound docs typo.
4087
408831 January 2008: Wouter
4089	- bg thread/process reads and writes the pipe nonblocking all the time
4090	  so that even if the pipe is buffered or so, the bg thread does not
4091	  block, and services both pipes and queries.
4092
409330 January 2008: Wouter
4094	- check trailing / on chrootdir in checkconf.
4095	- check if root hints and anchor files are in chrootdir.
4096	- no route to host tcp error is verbosity level 2.
4097	- removed unused send_reply_iov. and its configure check.
4098	- added prints of 'remote address is 1.2.3.4 port 53' to errors
4099	  from netevent; the basic socket errors.
4100
410128 January 2008: Wouter
4102	- fixup uninit use of buffer by libunbound (query id, flags) for
4103	  local_zone answers.
4104	- fixup uninit warning from random.c; also seems to fix sporadic
4105	  sigFPE coming out of openssl.
4106	- made openssl entropy warning more silent for library use. Needs
4107	  verbosity 1 now.
4108	- fixup forgotten locks for rbtree_searches on ctx->query tree.
4109	- random generator cleanup - RND_STATE_SIZE removed, and instead
4110	  a super-rnd can be passed at init to chain init random states.
4111	- test also does lock checks if available.
4112	- protect config access in libworker_setup().
4113	- libevent doesn't like comm_base_exit outside of runloop.
4114	- close fds after removing commpoints only (for epoll, kqueue).
4115
411625 January 2008: Wouter
4117	- added tpkg for asynclook and library use.
4118	- allows localhost to be queried when as a library.
4119	- fixup race condition between cancel and answer (in case of
4120	  really fast answers that beat the cancel).
4121	- please doxygen, put doxygen comment in one place.
4122	- asynclook -b blocking mode and test.
4123	- refactor asynclook, nicer code.
4124	- fixup race problems from opensll in rand init from library, with
4125	  a mutex around the rand init.
4126	- fix pass async_id=NULL to _async resolve().
4127	- rewrote _wait() routine, so that it is threadsafe.
4128	- cancelation is threadsafe.
4129	- asynclook extended test in tpkg.
4130	- fixed two races where forked bg process waits for (somehow shared?)
4131	  locks, so does not service the query pipe on the bg side.
4132	  Now those locks are only held for fg_threads and for bg_as_a_thread.
4133
413424 January 2008: Wouter
4135	- tested the cancel() function.
4136	- asynclook -c (cancel) feature.

4142	- new calls to set forwarding added to header and docs.
4143
414423 January 2008: Wouter
4145	- removed debug prints from if-auto, verb-algo enables some.
4146	- libunbound QUIT setup, remove memory leaks, when using threads
4147	  will share memory for passing results instead of writing it over
4148	  the pipe, only writes ID number over the pipe (towards the handler
4149	  thread that does process() ).
4150
415122 January 2008: Wouter
4152	- library code for async in libunbound/unbound.c.
4153	- fix link testbound.
4154	- fixup exit bug in mini_event.
4155	- background worker query enter and result functions.
4156	- bg query test application asynclook, it looks up multiple
4157	  hostaddresses (A records) at the same time.
4158
415921 January 2008: Wouter
4160	- libworker work, netevent raw commpoints, write_msg, serialize.
4161
416218 January 2008: Wouter
4163	- touch up of manpage for libunbound.
4164	- support for IP_RECVDSTADDR (for *BSD ip4).
4165	- fix for BSD, do not use ip4to6 mapping, make two sockets, once
4166	  ip6 and once ip4, uses socket options.
4167	- goodbye ip4to6 mapping.
4168	- update ldns-testpkts with latest version from ldns-trunk.
4169	- updated makedist for relative ldns pathnames.
4170	- library API with more information inside the result structure.
4171	- work on background resolves.
4172
417317 January 2008: Wouter
4174	- fixup configure in case -lldns is installed.
4175	- fixup a couple of doxygen warnings, about enum variables.
4176	- interface-automatic now copies the interface address from the
4177	  PKT_INFO structure as well.
4178	- manual page with library API, all on one page 'man libunbound'.
4179	- rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
4180
418116 January 2008: Wouter
4182	- incoming queries to the server with TC bit on are replied FORMERR.
4183	- interface-automatic replied the wrong source address on localhost
4184	  queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
4185	  to use ifnum=-1 to mean 'no interface, use kernel route'.
4186
418715 January 2008: Wouter
4188	- interface-automatic feature. experimental. Nice for anycast.
4189	- tpkg test for ip6 ancillary data.
4190	- removed debug prints.
4191	- porting experience, define for Solaris, test refined for BSD
4192	  compatibility. The feature probably will not work on OpenBSD.
4193	- makedist fixup for ldns-src in build-dir.
4194
419514 January 2008: Wouter
4196	- in no debug sets NDEBUG to remove asserts.
4197	- configure --enable-debug is needed for dependency generation
4198	  for assertions and for compiler warnings.
4199	- ldns.tgz updated with ldns-trunk (where buffer.h is updated).
4200	- fix lint, unit test in optimize mode.
4201	- default access control allows ::ffff:127.0.0.1 v6mapped localhost.
4202
420311 January 2008: Wouter
4204	- man page, warning removed.
4205	- added text describing the use of stub zones for private zones.
4206	- checkconf tests for bad hostnames (IP address), and for doubled
4207	  interface lines.
4208	- memory sizes can be given with 'k', 'Kb', or M or G appended.
4209
421010 January 2008: Wouter
4211	- typo in example.conf.
4212	- made using ldns-src that is included the package more portable
4213	  by linking with .lo instead of .o files in the ldns package.
4214	- nicer do-ip6: yes/no documentation.
4215	- nicer linking of libevent .o files.
4216	- man pages render correctly on solaris.
4217
42189 January 2008: Wouter
4219	- fixup openssl RAND problem, when the system is not configured to
4220	  give entropy, and the rng needs to be seeded.
4221
42228 January 2008: Wouter
4223	- print median and quartiles with extensive logging.
4224
42254 January 2008: Wouter
4226	- document misconfiguration in private network.
4227
42282 January 2008: Wouter
4229	- fixup typo in requirements.
4230	- document that 'refused' is a better choice than 'drop' for
4231	  the access control list, as refused will stop retries.
4232
42337 December 2007: Wouter
4234	- unbound-host has a -d option to show what happens. This can help
4235	  with debugging (why do I get this answer).
4236	- fixup CNAME handling, on nodata, sets and display canonname.
4237	- dot removed from CNAME display.
4238	- respect -v for NXDOMAINs.
4239	- updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
4240	- size_t to int for portability of the header file.
4241	- fixup bogus handling.
4242	- dependencies and lint for unbound-host.
4243
42446 December 2007: Wouter
4245	- library resolution works in foreground mode, unbound-host app
4246	  receives data.
4247	- unbound-host prints rdata using ldns.
4248	- unbound-host accepts trust anchors, and prints validation
4249	  information when you give -v.
4250
42515 December 2007: Wouter
4252	- locking in context_new() inside the function.
4253	- setup of libworker.
4254
42554 December 2007: Wouter
4256	- minor Makefile fixup.
4257	- moved module-stack code out of daemon/daemon into services/modstack,
4258	  preparing for code-reuse.
4259	- move context into own header file.
4260	- context query structure.
4261	- removed unused variable pwd from checkconf.
4262	- removed unused assignment from outside netw.
4263	- check timeval length of string.
4264	- fixup error in val_utils getsigner.
4265	- fixup same (*var) error in netblocktostr.
4266	- fixup memleak on parse error in localzone.
4267	- fixup memleak on packet parse error.
4268	- put ; after union in parser.y.
4269	- small hardening in iter_operate against iq==NULL.
4270	- hardening, if error reply with rcode=0 (noerror) send servfail.
4271	- fixup same (*var) error in find_rrset in msgparse, was harmless.
4272	- check return value of evtimer_add().
4273	- fixup lockorder in lruhash_reclaim(), building up a list of locked
4274	  entries one at a time. Instead they are removed and unlocked.
4275	- fptr_wlist for markdelfunc.
4276	- removed is_locked param from lruhash delkeyfunc.
4277	- moved bin_unlock during bin_split purely to please.
4278
42793 December 2007: Wouter
4280	- changed checkconf/ to smallapp/ to make room for more support tools.
4281	  (such as unbound-host).
4282	- install dirs created with -m 755 because they need to be accessible.
4283	- library extensive featurelist added to TODO.
4284	- please doxygen, lint.
4285	- library test application, with basic functionality.
4286	- fix for building in a subdirectory.
4287	- link lib fix for Leopard.
4288
428930 November 2007: Wouter
4290	- makefile that creates libunbound.la, basic file or libunbound.a
4291	  when creating static executables (no libtool).
4292	- more API setup.
4293
429429 November 2007: Wouter
4295	- 0.9 public API start.
4296
429728 November 2007: Wouter
4298	- Changeup plan for 0.8 - no complication needed, a simple solution
4299	  has been chosen for authoritative features.
4300	- you can use single quotes in the config file, so it is possible
4301	  to specify TXT records in local data.
4302	- fixup small memory problem in implicit transparent zone creation.
4303	- test for implicit zone creation and multiple RR RRsets local data.
4304	- local-zone nodefault test.
4305	- show testbound testlist on commit.
4306	- iterator normalizer changes CNAME chains ending in NXDOMAIN where
4307	  the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
4308	  domain exists).
4309	- nicer verbosity: 0 and 1 levels.
4310	- lower nonRDquery chance of eliciting wrongly typed validation
4311	  requiring message from the cache.
4312	- fix for nonRDquery validation typing; nodata is detected when
4313	  SOA record in auth section (all validation-requiring nodata messages
4314	  have a SOA record in authority, so this is OK for the validator),
4315	  and NS record is needed to be a referral.
4316	- duplicate checking when adding NSECs for a CNAME, and test.
4317	- created svn tag 0.8, after completing testbed tests.
4318
431927 November 2007: Wouter
4320	- per suggestion in rfc2308, replaced default max-ttl value with 1 day.
4321	- set size of msgparse lookup table to 32, from 1024, so that its size
4322	  is below the 2048 regional large size threshold, and does not cause
4323	  a call to malloc when a message is parsed.
4324	- update of memstats tool to print number of allocation calls.
4325	  This is what is taking time (not space) and indicates the avg size
4326	  of the allocations as well. region_alloc stat is removed.
4327
432822 November 2007: Wouter
4329	- noted EDNS in-the-middle dropping trouble as a TODO.
4330	  At this point theoretical, no user trouble has been reported.
4331	- added all default AS112 zones.
4332	- answers from local zone content.
4333		* positive answer, the rrset in question
4334		* nodata answer (exist, but not that type).
4335		* nxdomain answer (domain does not exist).
4336		* empty-nonterminal answer.
4337		* But not: wildcard, nsec, referral, rrsig, cname/dname,
4338			or additional section processing, NS put in auth.
4339	- test for correct working of static and transparent and couple
4340	  of important defaults (localhost, as112, reverses).
4341	  Also checks deny and refuse settings.
4342	- fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
4343
434421 November 2007: Wouter
4345	- local zone internal data setup.
4346
434720 November 2007: Wouter
4348	- 0.8 - str2list config support for double string config options.
4349	- local-zone and local-data options, config storage and documentation.
4350
435119 November 2007: Wouter
4352	- do not downcase NSEC and RRSIG for verification. Follows
4353	  draft-ietf-dnsext-dnssec-bis-updates-06.txt.
4354	- fixup leaking unbound daemons at end of tests.
4355	- README file updated.
4356	- nice libevent not found error.
4357	- README talks about gnu make.
4358	- 0.8: unit test for addr_mask and fixups for it.
4359	  and unit test for addr_in_common().
4360	- 0.8: access-control config file element.
4361	  and unit test rpl replay file.
4362	- 0.8: fixup address reporting from netevent.
4363
436416 November 2007: Wouter
4365	- privilege separation is not needed in unbound at this time.
4366	  TODO item marked as such.
4367	- created beta-0.7 branch for support.
4368	- tagged 0.7 for beta release.
4369	- moved trunk to 0.8 for 0.8(auth features) development.
4370	- 0.8: access control list setup.
4371
437215 November 2007: Wouter
4373	- review fixups from Jelte.
4374
437514 November 2007: Wouter
4376	- testbed script does not recreate configure, since its in svn now.
4377	- fixup checkconf test so that it does not test
4378	  /etc/unbound/unbound.conf.
4379	- tag 0.6.
4380
438113 November 2007: Wouter
4382	- remove debug print.
4383	- fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
4384
438512 November 2007: Wouter
4386	- fixup signal handling where SIGTERM could be ignored if a SIGHUP
4387	  arrives later on.
4388	- bugreports to unbound-bugs@nlnetlabs.nl
4389	- fixup testbound so it exits cleanly.
4390	- cleanup the caches on a reload, so that rrsetID numbers won't clash.
4391
43929 November 2007: Wouter
4393	- took ldns snapshot in repo.
4394	- default config file is /etc/unbound/unbound.conf.
4395	  If it doesn't exist, it is installed with the doc/example.conf file.
4396	  The file is not deleted on uninstall.
4397	- default listening is not all, but localhost interfaces.
4398
43998 November 2007: Wouter
4400	- Fixup chroot and drop user privileges.
4401	- new L root ip address in default hints.
4402
44031 November 2007: Wouter
4404	- Fixup of crash on reload, due to anchors in env not NULLed after
4405	  dealloc during deinit.
4406	- Fixup of chroot call. Happens after privileges are dropped, so
4407	  that checking the passwd entry still works.
4408	- minor touch up of clear() hashtable function.
4409	- VERB_DETAIL prints out what chdir, username, chroot is being done.
4410	- when id numbers run out, caches are cleared, as in design notes.
4411	  Tested with a mock setup with very few bits in id, it worked.
4412	- harden-dnssec-stripped: yes is now default. It insists on dnssec
4413	  data for trust anchors. Included tests for the feature.
4414
441531 October 2007: Wouter
4416	- cache-max-ttl config option.
4417	- building outside sourcedir works again.
4418	- defaults more secure:
4419		username: "unbound"
4420		chroot: "/etc/unbound"
4421	  The operator can override them to be less secure ("") if necessary.
4422	- fix horrible oversight in sorting rrset references in a message,
4423	  sort per reference key pointer, not on referencepointer itself.
4424	- pidfile: "/etc/unbound/unbound.pid" is now the default.
4425	- tests changed to reflect the updated default.
4426	- created hashtable clear() function that respects locks.
4427
442830 October 2007: Wouter
4429	- fixup assertion failure that relied on compressed names to be
4430	  smaller than uncompressed names. A packet from comrite.com was seen
4431	  to be compressed to a larger size. Added it as unit test.
4432	- quieter logging at low verbosity level for common tcp messages.
4433	- no greedy TTL update.
4434
443523 October 2007: Wouter
4436	- fixup (grand-)parent problem for dnssec-lameness detection.
4437	- fixup tests to do additional section processing for lame replies,
4438	  since the detection needs that.
4439	- no longer trust in query section in reply during dnssec lame detect.
4440	- dnssec lameness does not make the server never ever queried, but
4441	  non-preferred. If no other servers exist or answer, the dnssec lame
4442	  server is used; the fastest dnssec lame server is chosen.
4443	- added test then when trust anchor cannot be primed (nodata), the
4444	  insecure mode from unbound works.
4445	- Fixup max queries per thread, any more are dropped.
4446
444722 October 2007: Wouter
4448	- added donotquerylocalhost config option. Can be turned off for
4449	  out test cases.
4450	- ISO C compat changes.
4451	- detect RA-no-AA lameness, as LAME.
4452	- DNSSEC-lameness detection, as LAME.
4453	  See notes in requirements.txt for choices made.
4454	- tests for lameness detection.
4455	- added all to make test target; need unbound for fwd tests.
4456	- testbound does not pollute /etc/unbound.
4457
445819 October 2007: Wouter
4459	- added configure (and its files) to svn, so that the trunk is easier
4460	  to use. ./configure, config.guess, config.sub, ltmain.sh,
4461	  and config.h.in.
4462	- added yacc/lex generated files, util/configlexer.c,
4463	  util/configparser.c util/configparser.h, to svn.
4464	- without lex no attempt to use it.
4465	- unsecure response validation collated into one block.
4466	- remove warning about const cast of cfgfile name.
4467	- outgoing-interfaces can be different from service interfaces.
4468	- ldns-src configure is done during unbound configure and
4469	  ldns-src make is done during unbound make, and so inherits the
4470	  make arguments from the unbound make invocation.
4471	- nicer error when libevent problem causes instant exit on signal.
4472	- read root hints from a root hint file (like BIND does).
4473
447418 October 2007: Wouter
4475	- addresses are logged with errors.
4476	- fixup testcode fake event to remove pending before callback
4477	  since the callback may create new pending items.
4478	- tests updated because retries are now in iterator module.
4479	- ldns-testpkts code is checked for differences between unbound
4480	  and ldns by makedist.sh.
4481	- ldns trunk from today added in svn repo for fallback in case
4482	  no ldns is installed on the system.
4483	  make download_ldns refreshes the tarball with ldns svn trunk.
4484	- ldns-src.tar.gz is used if no ldns is found on the system, and
4485	  statically linked into unbound.
4486	- start of regional allocator code.
4487	- regional uses less memory and variables, simplified code.
4488	- remove of region-allocator.
4489	- alloc cache keeps a cache of recently released regional blocks,
4490	  up to a maximum.
4491	- make unit test cleanly free memory.
4492
449317 October 2007: Wouter
4494	- fixup another cycle detect and ns-addr timeout resolution bug.
4495	  This time by refusing delegations from the cache without addresses
4496	  when resolving a mandatory-glue nameserver-address for that zone.
4497	  We're going to have to ask a TLD server anyway; might as well be
4498	  the TLD server for this name. And this resolves a lot of cases where
4499	  the other nameserver names lead to cycles or are not available.
4500	- changed random generator from random(3) clone to arc4random wrapped
4501	  for thread safety. The random generator is initialised with
4502	  entropy from the system.
4503	- fix crash where failure to prime DNSKEY tried to print null pointer
4504	  in the log message.
4505	- removed some debug prints, only verb_algo (4) enables them.
4506	- fixup test; new random generator took new paths; such as one
4507	  where no scripted answer was available.
4508	- mark insecure RRs as insecure.
4509	- fixup removal of nonsecure items from the additional.
4510	- reduced timeout values to more realistic, 376 msec (262 msec has
4511	  90% of roundtrip times, 512 msec has 99% of roundtrip times.)
4512	- server selection failover to next server after timeout (376 msec).
4513
451416 October 2007: Wouter
4515	- no malloc in log_hex.
4516	- assertions around system calls.
4517	- protect against gethostname without ending zero.
4518	- ntop output is null terminated by unbound.
4519	- pidfile content null termination
4520	- various snprintf use sizeof(stringbuf) instead of fixed constant.
4521	- changed loopdetect % 8 with & 0x7 since % can become negative for
4522	  weird negative input and particular interpretation of integer math.
4523	- dname_pkt_copy checks length of result, to protect result buffers.
4524	  prints an error, this should not happen. Bad strings should have
4525	  been rejected earlier in the program.
4526	- remove a size_t underflow from msgreply size func.
4527
452815 October 2007: Wouter
4529	- nicer warning.
4530	- fix IP6 TCP, wrong definition check. With test package.
4531	- fixup the fact that the query section was not compressed to,
4532	  the code was there but was called by value instead of by reference.
4533	  And test for the case, uses xxd and nc.
4534	- more portable ip6 check for sockaddr types.
4535
45368 October 2007: Wouter
4537	- --disable-rpath option in configure for 64bit systems with
4538	  several dynamic lib dirs.
4539
45407 October 2007: Wouter
4541	- fixup tests for no AD bit in non-DO queries.
4542	- test that makes sure AD bit is not set on non-DO query.
4543
45446 October 2007: Wouter
4545	- removed logfile open early. It did not have the proper permissions;
4546	  it was opened as root instead of the user. And we cannot change user
4547	  id yet, since chroot and bind ports need to be done.
4548	- callback checks for event callbacks done from mini_event. Because
4549	  of deletions cannot do this from netevent. This means when using
4550	  libevent the protection does not work on event-callbacks.
4551	- fixup too small reply (did not zero counts).
4552	- fixup reply no longer AD bit when query without DO bit.
4553
45545 October 2007: Wouter
4555	- function pointer whitelist.
4556
45574 October 2007: Wouter
4558	- overwrite sensitive random seed value after use.
4559	- switch to logfile very soon if not -d (console attached).
4560	- error messages do not reveal the trustanchor contents.
4561	- start work on function pointer whitelists.
4562
45633 October 2007: Wouter
4564	- fix for multiple empty nonterminals, after multiple DSes in the
4565	  chain of trust.
4566	- mesh checks if modules are looping, and stops them.
4567	- refetch with CNAMEd nameserver address regression test added.
4568	- fixup line count bug in testcode, so testbound prints correct line
4569	  number with parse errors.
4570	- unit test for multiple ENT case.
4571	- fix for cname out of validated unsec zone.
4572	- fixup nasty id=0 reuse. Also added assertions to detect its
4573	  return (the assertion catches in the existing test cases).
4574
45751 October 2007: Wouter
4576	- skip F77, CXX, objC tests in configure step.
4577	- fixup crash in refetch glue after a CNAME.
4578	  and protection against similar failures (with error print).
4579
458028 September 2007: Wouter
4581	- test case for unbound-checkconf, fixed so it also checks the
4582	  interface: statements.
4583
458426 September 2007: Wouter
4585	- SIGHUP will reopen the log file.
4586	- Option to log to syslog.
4587	- please lint, fixup tests (that went to syslog on open, oops).
4588	- config check program.
4589
459025 September 2007: Wouter
4591	- tests for NSEC3. Fixup bitmap checks for NSEC3.
4592	- positive ANY response needs to check if wildcard expansion, and
4593	  check that original data did not exist.
4594	- tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
4595	  delegation, for abuse of child zone apex nsec3.
4596	- create 0.5 release tag.
4597
459824 September 2007: Wouter
4599	- do not make test programs by default.
4600	- But 'make test' will perform all of the tests.
4601	- Advertise builtin select libevent alternative when no libevent
4602	  is found.
4603	- signit can generate NSEC3 hashes, for generating tests.
4604	- multiple nsec3 paramaters in message test.
4605	- too high nsec3 iterations becomes insecure test.
4606
460721 September 2007: Wouter
4608	- fixup empty_DS_name allocated in wrong region (port DEC Alpha).
4609	- fixup testcode lock safety (port FreeBSD).
4610	- removes subscript has type char warnings (port Solaris 9).
4611	- fixup of field with format type to int (port MacOS/X intel).
4612	- added test for infinite loop case in nonRD answer validation.
4613	  It was a more general problem, but hard to reproduce. When an
4614	  unsigned rrset is being validated and the key fetched, the DS
4615	  sequence is followed, but if the final name has no DS, then no
4616	  proof is possible - the signature has been stripped off.
4617
461820 September 2007: Wouter
4619	- fixup and test for NSEC wildcard with empty nonterminals.
4620	- makedist.sh fixup for svn info.
4621	- acl features request in plan.
4622	- improved DS empty nonterminal handling.
4623	- compat with ANS nxdomain for empty nonterminals. Attempts the nodata
4624	  proof anyway, which succeeds in ANS failure case.
4625	- striplab protection in case it becomes -1.
4626	- plans for static and blacklist config.
4627
462819 September 2007: Wouter
4629	- comments about non-packed usage.
4630	- plan for overload support in 0.6.
4631	- added testbound tests for a failed resolution from the logs
4632	  and for failed prime when missing glue.
4633	- fixup so useless delegation points are not returned from the
4634	  cache. Also the safety belt is used if priming fails to complete.
4635	- fixup NSEC rdata not to be lowercased, bind compat.
4636
463718 September 2007: Wouter
4638	- wildcard nsec3 testcases, and fixup to get correct wildcard name.
4639	- validator prints subtype classification for debug.
4640
464117 September 2007: Wouter
4642	- NSEC3 hash cache unit test.
4643	- validator nsec3 nameerror test.
4644
464514 September 2007: Wouter
4646	- nsec3 nodata proof, nods proof, wildcard proof.
4647	- nsec3 support for cname chain ending in noerror or nodata.
4648	- validator calls nsec3 proof routines if no NSECs prove anything.
4649	- fixup iterator bug where it stored the answer to a cname under
4650	  the wrong qname into the cache. When prepending the cnames, the
4651	  qname has to be reset to the original qname.
4652
465313 September 2007: Wouter
4654	- nsec3 find matching and covering, ce proof, prove namerror msg.
4655
465612 September 2007: Wouter
4657	- fixup of manual page warnings, like for NSD bugreport.
4658	- nsec3 work, config, max iterations, filter, and hash cache.
4659
46606 September 2007: Wouter
4661	- fixup to find libevent on mac port install.
4662	- fixup size_t vs unsigned portability in validator/sigcrypt.
4663	- please compiler on different platforms, for unreachable code.
4664	- val_nsec3 file.
4665	- pthread_rwlock type is optional, in case of old pthread libs.
4666
46675 September 2007: Wouter
4668	- cname, name error validator tests.
4669	- logging of qtype ANY works.
4670	- ANY type answers get RRSIG in answer section of replies (but not
4671	  in other sections, unless DO bit is on).
4672	- testbound can replay a TCP query (set MATCH TCP in the QUERY).
4673	- DS and noDS referral validation test.
4674	- if you configure many trust anchors, parent trust anchors can
4675	  securely deny existance of child trust anchors, if validated.
4676	- not all *.name NSECs are present because a wildcard was matched,
4677	  and *.name NSECs can prove nodata for empty nonterminals.
4678	  Also, for wildcard name NSECs, check they are not from the parent
4679	  zone (for wildcarded zone cuts), and check absence of CNAME bit,
4680	  for a nodata proof.
4681	- configure option for memory allocation debugging.
4682	- port configure option for memory allocation to solaris10.
4683
46844 September 2007: Wouter
4685	- fixup of Leakage warning when serviced queries processed multiple
4686	  callbacks for the same query from the same server.
4687	- testbound removes config file from /tmp on failed exit.
4688	- fixup for referral cleanup of the additional section.
4689	- tests for cname, referral validation.
4690	- neater testbound tpkg output.
4691	- DNAMEs no longer match their apex when synthesized from the cache.
4692	- find correct signer name for DNAME responses.
4693	- wildcarded DNAME test and fixup code to detect.
4694	- prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
4695	  So that wildcarded CNAMEs get their NSEC with them to the answer.
4696	- test for a CNAME to a DNAME to a CNAME to an answer, all from
4697	  different domains, for key fetching and signature checking of
4698	  CNAME'd messages.
4699
47003 September 2007: Wouter
4701	- Fixed error in iterator that would cause assertion failure in
4702	  validator. CNAME to a NXDOMAIN response was collated into a response
4703	  with both a CNAME and the NXDOMAIN rcode. Added a test that the
4704	  rcode is changed to NOERROR (because of the CNAME).
4705	- timeout on tcp does not lead to spurious leakage detect.
4706	- account memory for name of lame zones, so that memory leakages does
4707	  not show lame cache growth as a leakage growth.
4708	- config setting for lameness cache expressed in bytes, instead of
4709	  number of entries.
4710	- tool too summarize allocations per code line.
4711
471231 August 2007: Wouter
4713	- can read bind trusted-keys { ... }; files, in a compatibility mode.
4714	- iterator should not detach target queries that it still could need.
4715	  the protection against multiple outstanding queries is moved to a
4716	  current_query num check.
4717	- validator nodata, positive, referral tests.
4718	- dname print can print '*' wildcard.
4719
472030 August 2007: Wouter
4721	- fixup override date config option.
4722	- config options to control memory usage.
4723	- caught bad free of un-alloced data in worker_send error case.
4724	- memory accounting for key cache (trust anchors and temporary cache).
4725	- memory accounting fixup for outside network tcp pending waits.
4726	- memory accounting fixup for outside network tcp callbacks.
4727	- memory accounting for iterator fixed storage.
4728	- key cache size and slabs config options.
4729	- lib crypto cleanups at exit.
4730
473129 August 2007: Wouter
4732	- test tool to sign rrsets for testing validator with.
4733	- added RSA and DSA test keys, public and private pairs, 512 bits.
4734	- default configuration is with validation enabled.
4735	  Only a trust-anchor needs to be configured for DNSSEC to work.
4736	- do not convert to DER for DSA signature verification.
4737	- validator replay test file, for a DS to DNSKEY DSA key prime and
4738	  positive response.
4739
474028 August 2007: Wouter
4741	- removed double use for udp buffers, that could fail,
4742	  instead performs a malloc to do the backup.
4743	- validator validates referral messages, by validating all the rrsets
4744	  and stores the rrsets in the cache. Further referral (nonRD queries)
4745	  replies are made from the rrset cache directly. Unless unchecked
4746	  rrsets are encountered, there are then validated.
4747	- enforce that signing is done by a parent domain (or same domain).
4748	- adjust TTL downwards if rrset TTL bigger than signature allows.
4749	- permissive mode feature, sets AD bit for secure, but bogus does
4750	  not give servfail (bogus is changed into indeterminate).
4751	- optimization of rrset verification. rr canonical sorting is reused,
4752	  for the same rrset. canonical rrset image in buffer is reused for
4753	  the same signature.
4754	- if the rrset is too big (64k exactly + large owner name) the
4755	  canonicalization routine will fail if it does not fit in buffer.
4756	- faster verification for large sigsets.
4757	- verb_detail mode reports validation failures, but not the entire
4758	  algorithm for validation. Key prime failures are reported as
4759	  verb_ops level.
4760
476127 August 2007: Wouter
4762	- do not garble the edns if a cache answer fails.
4763	- answer norecursive from cache if possible.
4764	- honor clean_additional setting when returning secure non-recursive
4765	  referrals.
4766	- do not store referral in msg cache for nonRD queries.
4767	- store verification status in the rrset cache to speed up future
4768	  verification.
4769	- mark rrsets indeterminate and insecure if they are found to be so.
4770	  and store this in the cache.
4771
477224 August 2007: Wouter
4773	- message is bogus if unsecure authority rrsets are present.
4774	- val-clean-additional option, so you can turn it off.
4775	- move rrset verification out of the specific proof types into one
4776	  routine. This makes the proof routines prettier.
4777	- fixup cname handling in validator, cname-to-positive and cname-to-
4778	  nodata work.
4779	- Do not synthesize DNSKEY and DS responses from the rrset cache if
4780	  the rrset is from the additional section. Signatures may have
4781	  fallen off the packet, and cause validation failure.
4782	- more verbose signature date errors (with the date attached).
4783	- increased default infrastructure cache size. It is important for
4784	  performance, and 1000 entries are only 212k (or a 400 k total cache
4785	  size). To 10000 entries (for 2M entries, 4M cache size).
4786
478723 August 2007: Wouter
4788	- CNAME handling - move needs_validation to before val_new().
4789	  val_new() setups the chase-reply to be an edited copy of the msg.
4790	  new classification, and find signer can find for it.
4791	  removal of unsigned crap from additional, and query restart for
4792	  cname.
4793	- refuse to follow wildcarded DNAMEs when validating.
4794	  But you can query for qtype ANY, or qtype DNAME and validate that.
4795
479622 August 2007: Wouter
4797	- bogus TTL.
4798	- review - use val_error().
4799
480021 August 2007: Wouter
4801	- ANY response validation.
4802	- store security status in cache.
4803	- check cache security status and either send the query to be
4804	  validated, return the query to client, or send servfail to client.
4805	  Sets AD bit on validated replies.
4806	- do not examine security status on an error reply in mesh_done.
4807	- construct DS, DNSKEY messages from rrset cache.
4808	- manual page entry for override-date.
4809
481020 August 2007: Wouter
4811	- validate and positive validation, positive wildcard NSEC validation.
4812	- nodata validation, nxdomain validation.
4813
481418 August 2007: Wouter
4815	- process DNSKEY response in FINDKEY state.
4816
481717 August 2007: Wouter
4818	- work on DS2KE routine.
4819	- val_nsec.c for validator NSEC proofs.
4820	- unit test for NSEC bitmap reading.
4821	- dname iswild and canonical_compare with unit tests.
4822
482316 August 2007: Wouter
4824	- DS sig unit test.
4825	- latest release libevent 1.3c and 1.3d have threading fixed.
4826	- key entry fixup data pointer and ttl absolute.
4827	- This makes a key-prime succeed in validator, with DS or DNSKEY as
4828	  trust-anchor.
4829	- fixup canonical compare byfield routine, fix bug and also neater.
4830	- fixed iterator response type classification for queries of type
4831	  ANY and NS.
4832	  dig ANY gives sometimes NS rrset in AN and NS section, and parser
4833	  removes the NS section duplicate. dig NS gives sometimes the NS
4834	  in the answer section, as referral.
4835	- validator FINDKEY state.
4836
483715 August 2007: Wouter
4838	- crypto calls to verify signatures.
4839	- unit test for rrsig verification.
4840
484114 August 2007: Wouter
4842	- default outgoing ports changed to avoid port 2049 by default.
4843	  This port is widely blocked by firewalls.
4844	- count infra lameness cache in memory size.
4845	- accounting of memory improved
4846	- outbound entries are allocated in the query region they are for.
4847	- extensive debugging for memory allocations.
4848	- --enable-lock-checks can be used to enable lock checking.
4849	- protect undefs in config.h from autoheaders ministrations.
4850	- print all received udp packets. log hex will print on multiple
4851	  lines if needed.
4852	- fixed error in parser with backwards rrsig references.
4853	- mark cycle targets for iterator did not have CD flag so failed
4854	  its task.
4855
485613 August 2007: Wouter
4857	- fixup makefile, if lexer is missing give nice error and do not
4858	  mess up the dependencies.
4859	- canonical compare routine updated.
4860	- canonical hinfo compare.
4861	- printout list of the queries that the mesh is working on.
4862
486310 August 2007: Wouter
4864	- malloc and free overrides that track total allocation and frees.
4865	  for memory debugging.
4866	- work on canonical sort.
4867
48689 August 2007: Wouter
4869	- canonicalization, signature checks
4870	- dname signature label count and unit test.
4871	- added debug heap size print to memory printout.
4872	- typo fixup in worker.c
4873	- -R needed on solaris.
4874	- validator override option for date check testing.
4875
48768 August 2007: Wouter
4877	- ldns _raw routines created (in ldns trunk).
4878	- sigcrypt DS digest routines
4879	- val_utils uses sigcrypt to perform signature cryptography.
4880	- sigcrypt keyset processing
4881
48827 August 2007: Wouter
4883	- security status type.
4884	- security status is copied when rdata is equal for rrsets.
4885	- rrset id is updated to invalidate all the message cache entries
4886	  that refer to NSEC, NSEC3, DNAME rrsets that have changed.
4887	- val_util work
4888	- val_sigcrypt file for validator signature checks.
4889
48906 August 2007: Wouter
4891	- key cache for validator.
4892	- moved isroot and dellabel to own dname routines, with unit test.
4893
48943 August 2007: Wouter
4895	- replanning.
4896	- scrubber check section of lame NS set.
4897	- trust anchors can be in config file or read from zone file,
4898	  DS and DNSKEY entries.
4899	- unit test trust anchor storage.
4900	- trust anchors converted to packed rrsets.
4901	- key entry definition.
4902
49032 August 2007: Wouter
4904	- configure change for latest libevent trunk version (needs -lrt).
4905	- query_done and walk_supers are moved out of module interface.
4906	- fixup delegation point duplicates.
4907	- fixup iterator scrubber; lame NS set is let through the scrubber
4908	  so that the classification is lame.
4909	- validator module exists, and does nothing but pass through,
4910	  with calling of next module and return.
4911	- validator work.
4912
49131 August 2007: Wouter
4914	- set version to 0.5
4915	- module work for module to module interconnections.
4916	- config of modules.
4917	- detect cycle takes flags.
4918
491931 July 2007: Wouter
4920	- updated plan
4921	- release 0.4 tag.
4922
492330 July 2007: Wouter
4924	- changed random state init, so that sequential process IDs are not
4925	  cancelled out by sequential thread-ids in the random number seed.
4926	- the fwd_three test, which sends three queries to unbound, and
4927	  unbound is kept waiting by ldns-testns for 3 seconds, failed
4928	  because the retry timeout for default by unbound is 3 seconds too,
4929	  it would hit that timeout and fail the test. Changed so that unbound
4930	  is kept waiting for 2 seconds instead.
4931
493227 July 2007: Wouter
4933	- removed useless -C debug option. It did not work.
4934	- text edit of documentation.
4935	- added doc/CREDITS file, referred to by the manpages.
4936	- updated planning.
4937
493826 July 2007: Wouter
4939	- cycle detection, for query state dependencies. Will attempt to
4940	  circumvent the cycle, but if no other targets available fails.
4941	- unit test for AXFR, IXFR response.
4942	- test for cycle detection.
4943
494425 July 2007: Wouter
4945	- testbound read ADDRESS and check it.
4946	- test for version.bind and friends.
4947	- test for iterator chaining through several referrals.
4948	- test and fixup for refetch for glue. Refetch fails if glue
4949	  is still not provided.
4950
495124 July 2007: Wouter
4952	- Example section in config manual.
4953	- Addr stored for range and moment in replay.
4954
495520 July 2007: Wouter
4956	- Check CNAME chain before returning cache entry with CNAMEs.
4957	- Option harden-glue, default is on. It will discard out of zone
4958	  data. If disabled, performance is faster, but spoofing attempts
4959	  become a possibility. Note that still normalize scrubbing is done,
4960	  and that the potentially spoofed data is used for infrastructure
4961	  and not returned to the client.
4962	- if glue times out, refetch by asking parent of delegation again.
4963	  Much like asking for DS at the parent side.
4964	- TODO items from forgery-resilience draft.
4965	  and on memory handling improvements.
4966	- renamed module_event_timeout to module_event_noreply.
4967	- memory reporting code; reports on memory usage after handling
4968	  a network packet (not on cache replies).
4969
497019 July 2007: Wouter
4971	- shuffle NS selection when getting nameserver target addresses.
4972	- fixup of deadlock warnings, yield cpu in checklock code so that
4973	  freebsd scheduler selects correct process to run.
4974	- added identity and version config options and replies.
4975	- store cname messages complete answers.
4976
497718 July 2007: Wouter
4978	- do not query addresses, 127.0.0.1, and ::1 by default.
4979
498017 July 2007: Wouter
4981	- forward zone options in config file.
4982	- forward per zone in iterator. takes precendence over stubs.
4983	- fixup commithooks.
4984	- removed forward-to and forward-to-port features, subsumed by
4985	  new forward zones.
4986	- fix parser to handle absent server: clause.
4987	- change untrusted rrset test to account for scrubber that is now
4988	  applied during the test (which removes the poison, by the way).
4989	- feature, addresses can be specified with @portnumber, like nsd.conf.
4990	- test config files changed over to new forwarder syntax.
4991
499227 June 2007: Wouter
4993	- delete of mesh does a postorder traverse of the tree.
4994	- found and fixed a memory leak. For TTL=0 messages, that would
4995	  not be cached, instead the msg-replyinfo structure was leaked.
4996	- changed server selection so it will filter out hosts that are
4997	  unresponsive. This is defined as a host with the maximum rto value.
4998	  This means that unbound tried the host for retries up to 120 secs.
4999	  The rto value will time out after host-ttl seconds from the cache.
5000	  This keeps such unresolvable queries from taking up resources.
5001	- utility for keeping histogram.
5002
500326 June 2007: Wouter
5004	- mesh is called by worker, and iterator uses it.
5005	  This removes the hierarchical code.
5006	  QueryTargets state and Finished state are merged for iterator.
5007	- forwarder mode no longer sets AA bit on first reply.
5008	- rcode in walk_supers is not needed.
5009
501025 June 2007: Wouter
5011	- more mesh work.
5012	- error encode routine for ease.
5013
501422 June 2007: Wouter
5015	- removed unused _node iterator value from rbtree_t. Takes up space.
5016	- iterator can handle querytargets state without a delegation point
5017	  set, so that a priming(stub) subquery error can be handled.
5018	- iterator stores if it is priming or not.
5019	- log_query_info() neater logging.
5020	- changed iterator so that it does not alter module_qstate.qinfo
5021	  but keeps a chase query info. Also query_flags are not altered,
5022	  the iterator uses chase_flags.
5023	- fixup crash in case no ports for the family exist.
5024
502521 June 2007: Wouter
5026	- Fixup secondary buffer in case of error callback.
5027	- cleanup slumber list of runnable states.
5028	- module_subreq_depth fails to work in slumber list.
5029	- fixup query release for cached results to sub targets.
5030	- neater error for tcp connection failure, shows addr in verbose.
5031	- rbtree_init so that it can be used with preallocated memory.
5032
503320 June 2007: Wouter
5034	- new -C option to enable coredumps after forking away.
5035	- doc update.
5036	- fixup CNAME generation by scrubber, and memory allocation of it.
5037	- fixup deletion of serviced queries when all callbacks delete too.
5038	- set num target queries to 0 when you move them to slumber list.
5039	- typo in check caused subquery errors to be ignored, fixed.
5040	- make lint happy about rlim_t.
5041	- freeup of modules after freeup of module-states.
5042	- duplicate replies work, this uses secondary udp buffer in outnet.
5043
504419 June 2007: Wouter
5045	- nicer layout in stats.c, review 0.3 change.
5046	- spelling improvement, review 0.3 change.
5047	- uncapped timeout for server selection, so that very fast or slow
5048	  servers will stand out from the rest.
5049	- target-fetch-policy: "3 2 1 0 0" config setting.
5050	- fixup queries answered without RD bit (for root prime results).
5051	- refuse AXFR and IXFR requests.
5052	- fixup RD flag in error reply from iterator. fixup RA flag from
5053	  worker error reply.
5054	- fixup encoding of very short edns buffer sizes, now sets TC bit.
5055	- config options harden-short-bufsize and harden-large-queries.
5056
505718 June 2007: Wouter
5058	- same, move subqueries to slumber list when first has resolved.
5059	- fixup last fix for duplicate callbacks.
5060	- another offbyone in targetcounter. Also in Java prototype by the way.
5061
506215 June 2007: Wouter
5063	- if a query asks to be notified of the same serviced query result
5064	  multiple times, this will succeed. Only one callback will happen;
5065	  multiple outbound-list entries result (but the double cleanup of it
5066	  will not matter).
5067	- when iterator moves on due to CNAME or referral, it will remove
5068	  the subqueries (for other targets). These are put on the slumber
5069	  list.
5070	- state module wait subq is OK with no new subqs, an old one may have
5071	  stopped, with an error, and it is still waiting for other ones.
5072	- if a query loops, halt entire query (easy way to clean up properly).
5073
507414 June 2007: Wouter
5075	- num query targets was > 0 , not >= 0 compared, so that fetch
5076	  policy of 0 did nothing.
5077
507813 June 2007: Wouter
5079	- debug option: configure --enable-static-exe for compile where
5080	  ldns and libevent are linked statically. Default is off.
5081	- make install and make uninstall. Works with static-exe and without.
5082	  installation of unbound binary and manual pages.
5083	- alignement problem fix on solaris 64.
5084	- fixup address in case of TCP error.
5085
508612 June 2007: Wouter
5087	- num target queries was set to 0 at a bad time. Default it to 0 and
5088	  increase as target queries are done.
5089	- synthesize CNAME and DNAME responses from the cache.
5090	- Updated doxygen config for doxygen 1.5.
5091	- aclocal newer version.
5092	- doxygen 1.5 fixes for comments (for the strict check on docs).
5093
509411 June 2007: Wouter
5095	- replies on TCP queries have the address field set in replyinfo,
5096	  for serviced queries, because the initiator does not know that
5097	  a TCP fallback has occured.
5098	- omit DNSSEC types from nonDO replies, except if qtype is ANY or
5099	  if qtype directly queries for the type (and then only show that
5100	  'unknown type' in the answer section).
5101	- fixed message parsing where rrsigs on their own would be put
5102	  in the signature list over the rrsig type.
5103
51047 June 2007: Wouter
5105	- fixup error in double linked list insertion for subqueries and
5106	  for outbound list of serviced queries for iterator module.
5107	- nicer printout of outgoing port selection.
5108	- fixup cname target readout.
5109	- nicer debug output.
5110	- fixup rrset counts when prepending CNAMEs to the answer.
5111	- fixup rrset TTL for prepended CNAMEs.
5112	- process better check for looping modules, and which submodule to
5113	  run next.
5114	- subreq insertion code fixup for slumber list.
5115	- VERB_DETAIL, verbosity: 2 level gives short but readable output.
5116	  VERB_ALGO, verbosity: 3 gives extensive output.
5117	- fixup RA bit in cached replies.
5118	- fixup CNAME responses from the cache no longer partial response.
5119	- error in network send handled without leakage.
5120	- enable ip6 from config, and try ip6 addresses if available,
5121	  if ip6 is not connected, skips to next server.
5122
51235 June 2007: Wouter
5124	- iterator state finished.
5125	- subrequests without parent store in cache and stop.
5126	- worker slumber list for ongoing promiscuous queries.
5127	- subrequest error handling.
5128	- priming failure returns SERVFAIL.
5129	- priming gives LAME result, returns SERVFAIL.
5130	- debug routine to print dns_msg as handled by iterator.
5131	- memleak in config file stubs fixup.
5132	- more small bugs, in scrubber, query compare no ID for lookup,
5133	  in dname validation for NS targets.
5134	- sets entry.key for new special allocs.
5135	- lognametypeclass can display unknown types and classes.
5136
51374 June 2007: Wouter
5138	- random selection of equally preferred nameserver targets.
5139	- reply info copy routine. Reuses existing code.
5140	- cache lameness in response handling.
5141	- do not touch qstate after worker_process_query because it may have
5142	  been deleted by that routine.
5143	- Prime response state.
5144	- Process target response state.
5145	- some memcmp changed to dname_compare for case preservation.
5146
51471 June 2007: Wouter
5148	- normalize incoming messages. Like unbound-java, with CNAME chain
5149	  checked, DNAME checked, CNAME's synthesized, glue checked.
5150	- sanitize incoming messages.
5151	- split msgreply encode functions into own file msgencode.c.
5152	- msg_parse to queryinfo/replyinfo conversion more versatile.
5153	- process_response, classify response, delegpt_from_message.
5154
515531 May 2007: Wouter
5156	- querytargets state.
5157	- dname_subdomain_c() routine.
5158	- server selection, based on RTT. ip6 is filtered out if not available,
5159	  and lameness is checked too.
5160	- delegation point copy routine.
5161
516230 May 2007: Wouter
5163	- removed FLAG_CD from message and rrset caches. This was useful for
5164	  an agnostic forwarder, but not for a sophisticated (trust value per
5165	  rrset enabled) cache.
5166	- iterator reponse typing.
5167	- iterator cname handle.
5168	- iterator prime start.
5169	- subquery work.
5170	- processInitRequest and processInitRequest2.
5171	- cache synthesizes referral messages, with DS and NSEC.
5172	- processInitRequest3.
5173	- if a request creates multiple subrequests these are all activated.
5174
517529 May 2007: Wouter
5176	- routines to lock and unlock array of rrsets moved to cache/rrset.
5177	- lookup message from msg cache (and copy to region).
5178	- fixed cast error in dns msg lookup.
5179	- message with duplicate rrset does not increase its TTLs twice.
5180	- 'qnamesize' changed to 'qname_len' for similar naming scheme.
5181
518225 May 2007: Wouter
5183	- Acknowledge use of unbound-java code in iterator. Nicer readme.
5184	- services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
5185	  rrset cache from module environment.
5186	- packed rrset key has type and class as easily accessable struct
5187	  members. They are still kept in network format for fast msg encode.
5188	- dns cache find_delegation routine.
5189	- iterator main functions setup.
5190	- dns cache lookup setup.
5191

5198
519923 May 2007: Wouter
5200	- outside network does precise timers for roundtrip estimates for rtt

5202	- cleaner iterator sockaddr conversion of forwarder address.
5203	- iterator/iter_utils and iter_delegpt setup.
5204	- root hints.
5205

5208	  outbound entry to the module.
5209	- testbound support for new serviced queries.
5210	- test for retry to TCP cannot use testbound any longer.

5212	- fixes for no-locking compile.
5213	- mini_event timer precision and fix for change in timeouts during
5214	  timeout callback. Fix for fwd_three tests, performed nonexit query.
5215
521621 May 2007: Wouter
5217	- small comment on hash table locking.
5218	- outside network serviced queries, contain edns and tcp fallback,
5219	  and udp retries and rtt timing.
5220
522116 May 2007: Wouter
5222	- lruhash_touch() would cause locking order problems. Fixup in
5223	  lock-verify in case locking cycle is found.
5224	- services/cache/rrset.c for rrset cache code.
5225	- special rrset_cache LRU updating function that uses the rrset id.

5235	- Port to OS/X and Dec Alpha. Printf format and alignment fixes.
5236	- extensive lock debug report on join timeout.
5237	- proper RTT calculation, in utility code.
5238	- setup of services/cache/infra, host cache.
5239

5267	- EDNS read from query, used to make reply smaller.
5268	- advertised edns value constants.
5269	- EDNS BADVERS response, if asked for too high edns version.
5270	- EDNS extended error reponses once the EDNS record from the query
5271	  has successfully been parsed.
5272
52734 May 2007: Wouter
5274	- msgreply sizefunc is more accurate.

5277	  alloc cache to store released keys.
5278	- alloc cache special_release() locks if necessary.
5279	- rrset trustworthiness type added.
5280	- thread keeps a scratchpad region for handling messages.

5295	- more dname unit tests.
5296	- message encoding creates truncated TC flagged messages if they do
5297	  not fit, and will leave out (whole)rrsets from additional if needed.
5298
52991 May 2007: Wouter
5300	- decompress query section, extremely lenient acceptance.
5301	  But only for answers from other servers, not for plain queries.
5302	- compression and decompression test cases.
5303	- some stats added.
5304	- example.conf interface: line is changed from 127.0.0.1 which leads
5305	  to problems if used (restricting communication to the localhost),
5306	  to a documentation and test address.
5307
530827 April 2007: Wouter
5309	- removed iov usage, it is not good for dns message encoding.

538110 April 2007: Wouter
5382	- Improved alignment of reply_info packet, nice for 32 and 64 bit.
5383	- Put RRset counts in reply_info, because the number of RRs can change
5384	  due to RRset updates.

5485
54869 March 2007: Wouter

5502	  contention measurement.
5503
55046 March 2007: Wouter
5505	- Testbed works with threading (different machines, different options).
5506	- alloc work, does the special type.
5507
55082 March 2007: Wouter
5509	- do not compile fork funcs unless needed. Otherwise will give
5510	  type errors as their typedefs have not been enabled.
5511	- log shows thread numbers much more nicely (and portably).
5512	- even on systems with nonthreadsafe libevent signal handling,

5514	  Reloads will not work, and exit is not graceful.
5515	- start of alloc framework layout.
5516

5518	- Signals, libevent and threads work well, with libevent patch and
5519	  changes to code (close after event_del).
5520	- set ipc pipes nonblocking.
5521
552227 February 2007: Wouter
5523	- ub_thread_join portable definition.
5524	- forking is used if no threading is available.
5525	  Tested, it works, since pipes work across processes as well.
5526	  Thread_join is replaced with waitpid.
5527	- During reloads the daemon will temporarily handle signals,
5528	  so that they do not result in problems.
5529	- Also randomize the outgoing port range for tests.
5530	- If query list is full, will stop selecting listening ports for read.
5531	  This makes all threads service incoming requests, instead of one.
5532	  No memory is leaking during reloads, service of queries, etc.
5533	- test that uses ldns-testns -f to test threading. Have to answer
5534	  three queries at the same time.
5535	- with verbose=0 operates quietly.
5536
553726 February 2007: Wouter
5538	- ub_random code used to select ID and port.
5539	- log code prints thread id.
5540	- unbound can thread itself, with reload(HUP) and quit working
5541	  correctly.
5542	- don't open pipes for #0, doesn't need it.
5543	- listens to SIGTERM, SIGQUIT, SIGINT (all quit) and SIGHUP (reload).
5544
554523 February 2007: Wouter
5546	- Can do reloads on sigHUP. Everything is stopped, and freed,
5547	  except the listening ports. Then the config file is reread.
5548	  And everything is started again (and listening ports if needed).
5549	- Ports for queries are shared.
5550	- config file added interface:, chroot: and username:.
5551	- config file: directory, logfile, pidfile. And they work too.
5552	- will daemonize by default now. Use -d to stay in the foreground.
5553	- got BSD random[256 state] code, made it threadsafe. util/random.
5554
555522 February 2007: Wouter
5556	- Have a config file. Removed commandline options, moved to config.

5566	- added yacc and lex configure, and config file parsing code.
5567	  also makedist.sh, and manpage.
5568	- put include errno.h in config.h
5569
557019 February 2007: Wouter
5571	- Created 0.0 svn tag.
5572	- added acx_pthread.m4 autoconf check for pthreads from
5573	  the autoconf archive. It is GPL-with-autoconf-exception Licensed.
5574	  You can specify --with-pthreads, or --without-pthreads to configure.
5575
557616 February 2007: Wouter
5577	- Updated testbed script, works better by using make on remote end.
5578	- removed check decls, we can compile without them.
5579	- makefile supports LIBOBJ replacements.
5580	- docs checks ignore compat code.
5581	- added util/mini-event.c and .h, a select based alternative used with
5582	  ./configure --with-libevent=no
5583	  It is limited to 1024 file descriptors, and has less features.
5584	- will not create ip6 sockets if ip6 not on the machine.
5585
558615 February 2007: Wouter
5587	- port to FreeBSD 4.11 Dec Alpha. Also works on Solaris 10 sparc64,
5588	  Solaris 9, FreeBSD 6, Linux i386 and OSX powerpc.
5589	- malloc rndstate, so that it is aligned for access.
5590	- fixed rbtree cleanup with postorder traverse.
5591	- fixed pending messages are deleted when handled.
5592	- You can control verbosity; default is not verbose, every -v
5593	  adds more verbosity.
5594
559514 February 2007: Wouter
5596	- Included configure.ac changes from ldns.
5597	- detect (some) headers before the standards check.
5598	- do not use isblank to test c99, since its not available on solaris9.
5599	- review of testcode.
5600		* entries in a RANGE are no longer reversed.
5601		* print name of file with replay entry parse errors.
5602	- port to OSX: cast to int for some prints of sizet.
5603	- Makefile copies ldnstestpkts.c before doing dependencies on it.
5604

56247 February 2007: Wouter
5625	- return answer with the same ID as query was sent with.
5626	- created udp forwarder test. I've done some effort to make it perform
5627	  quickly. After servers are created, no big sleep statements but
5628	  it checks the logfiles to see if servers have come up. Takes 0.14s.
5629	- set addrlen value when calling recvfrom.
5630	- comparison of addrs more portable.
5631	- LIBEVENT option for testbed to set libevent directory.
