572	  for secure domain name system traffic.
573	  If you used to rely on the older default of port 443, you have
574	  to put a clause in unbound.conf for that.  The new value is likely

705	  put text in the example configuration and man page to that effect.
706
70710 May 2015: Wouter
708	- Change syntax of particular validator error to be easier for
709	  machine parse, swap rrset and ip adres info so it looks like:
710	  validation failure <www.example.nl. TXT IN>: signature crypto
711	  failed from 2001:DB8:7:bba4::53 for <*.example.nl. NSEC IN>
712

73016 April 2015: Wouter
731	- Add local-zone type inform_deny, that logs query and drops answer.

735	- Fix bug#664: libunbound python3 related fixes (from Tomas Hozza)
736	  Use print_function also for Python2.

74110 April 2015: Wouter
742	- unbound-control ratelimit_list lists high rate domains.
743	- ratelimit feature, ratelimit: 100, or some sensible qps, can be

746	- Fix that get_option for cache-sizes does not print double newline.
747	- Fix#663: ssl handshake fails when using unix socket because dh size
748	  is too small.

751	- Fix crash in dnstap: Do not try to log TCP responses after timeout.
752
7537 April 2015: Wouter
754	- Libunbound skips dos-line-endings from etc/hosts.
755	- Unbound exits with a fatal error when the auto-trust-anchor-file
756	  fails to be writable.  This is seconds after startup.  You can
757	  load a readonly auto-trust-anchor-file with trust-anchor-file.
758	  The file has to be writable to notice the trust anchor change,
759	  without it, a trust anchor change will be unnoticed and the system
760	  will then become inoperable.
761	- unbound-control list_insecure command shows the negative trust
762	  anchors currently configured, patch from Jelte Jansen.
763
7642 April 2015: Wouter

809
8105 March 2015: Wouter
811	- contrib/unbound_smf22.tar.gz: Solaris SMF installation/removal

814	- stats reports tcp usage, of incoming-num-tcp buffers.
815
8164 March 2015: Wouter
817	- Patch from Brad Smith that syncs compat/getentropy_linux with
818	  OpenBSD's version (2015-03-04).
819	- 0x20 fallback improved: servfail responses do not count as missing
820	  comparisons (except if all responses are errors),
821	  inability to find nameservers does not fail equality comparisons,
822	  many nameservers does not try to compare more than max-sent-count,
823	  parse failures start 0x20 fallback procedure.
824	- store caps_response with best response in case downgrade response
825	  happens to be the last one.

1184	- Code cleanup patch from Dag-Erling Smorgrav, with compiler issue
1185	  fixes from FreeBSD's copy of Unbound, he notes:
1186	  Generate unbound-control-setup.sh at build time so it respects
1187	  prefix and sysconfdir from the configure script.  Also fix the
1188	  umask to match the comment, and the comment to match the umask.
1189	  Add const and static where needed.  Use unions instead of
1190	  playing pointer poker.  Move declarations that are needed in
1191	  multiple source files into a shared header.  Move sldns_bgetc()
1192	  from parse.c to buffer.c where it belongs.  Introduce a new
1193	  header file, worker.h, which declares the callbacks that
1194	  all workers must define.  Remove those declarations from
1195	  libworker.h.	Include the correct headers in the correct places.
1196	  Fix a few dummy callbacks that don't match their prototype.
1197	  Fix some casts.  Hide the sbrk madness behind #ifdef HAVE_SBRK.
1198	  Remove a useless printf which breaks reproducible builds.
1199	  Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
1200	  no longer used.  Add unbound-control-setup.sh to the list of
1201	  generated files.  The prototype for libworker_event_done_cb()
1202	  needs to be moved from libunbound/libworker.h to
1203	  libunbound/worker.h.
1204	- Fixup out-of-directory compile with unbound-control-setup.sh.in.
1205	- make depend.

121616 May 2014: Wouter
1217	- Updated create_unbound_ad_servers and unbound_cache scripts from

123929 April 2014: Wouter
1240	- iana portlist updated.
1241	- Add unbound-control flush_negative that flushed nxdomains, nodata,

1244	  negatively cached from the previous network.
1245
124623 April 2014: Wouter
1247	- Patch from Jeremie Courreges-Anglas to use arc4random_uniform

1264	  outgoing queries made in the previous statistics interval.
1265	- Fix #567: unbound lists if forward zone is secure or insecure with
1266	  +i annotation in output of list_forwards, also for list_stubs
1267	  (for NetworkManager integration.)
1268	- Fix #554: use unsigned long to print 64bit statistics counters on
1269	  64bit systems.
1270	- Fix #558: failed prefetch lookup does not remove cached response
1271	  but delays next prefetch (in lieu of caching a SERVFAIL).
1272	- Fix #545: improved logging, the ip address of the error is printed
1273	  on the same log-line as the error.
1274
12758 April 2014: Wouter

1307	- iana portlist updated.
1308
130920 February 2014: Matthijs
1310	- Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
1311	  received. This is okay according 4035, but not after revising
1312	  existence in 4592.  NSEC empty non-terminals exist and thus the
1313	  RCODE should have been NOERROR. If this occurs, and the RRsets
1314	  are secure, we set the RCODE to NOERROR and the security status
1315	  of the response is also considered secure.
1316
131714 February 2014: Wouter
1318	- Works on Minix (3.2.1).

1349	  are not portable; they cannot be read (for sure) on other computers.
1350	- fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
1351	  parse sldns.
1352
135330 January 2014: Wouter
1354	- delay-close does not act if there are udp-wait queries, so that
1355	  it does not make a socketdrain DoS easier.
1356
135728 January 2014: Wouter
1358	- iana portlist updated.
1359	- iana portlist test updated so it does not touch the source
1360	  if there are no changes.
1361	- delay-close: msec option that delays closing ports for which
1362	  the UDP reply has timed out.  Keeps the port open, only accepts
1363	  the correct reply.  This correct reply is not used, but the port
1364	  is open so that no port-denied ICMPs are generated.
1365
136627 January 2014: Wouter
1367	- reuseport is attempted, then fallback to without on failure.
1368
136924 January 2014: Wouter

1371	- iana portlist updated.
1372	- unbound-event.h is installed if you configure --enable-event-api.
1373	- speed up unbound (reports say it could be up to 10%), by reducing

1414	  is called by libunbound in the mesh attach.
1415	- Accept ip-address: as an alternative for interface: for
1416	  consistency with nsd.conf syntax.

1425	- Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
1426	  more specific interface port 53 can be used at the same time, and
1427	  one of the daemons is unbound.
1428	- iana portlist update.
1429	- separate ldns into core ldns inside ldns/ subdirectory.  No more
1430	  --with-ldns is needed and unbound does not rely on libldns.
1431	- portability fixes for new USE_SLDNS ldns subdir codebase.
1432
143322 Oct 2013: Wouter
1434	- Patch from Neel Goyal: Add an API call to set an event base on an
1435	  existing ub_ctx.  This basically just destroys the current worker and
1436	  sets the event base to the current.  And fix a deadlock in
1437	  ub_resolve_event – the cfglock is held when libworker_create is
1438	  called.  This ends up trying to acquire the lock again in
1439	  context_obtain_alloc in the call chain.
1440	- Fix #528: if very high logging (4 or more) segfault on allow_snoop.
1441
144226 Sep 2013: Wouter

192719 March 2012: Wouter
1928	- iana portlist updated.
1929	- fix to locate nameservers for DS lookup with NS fetches.
1930
193116 March 2012: Wouter
1932	- Patch for access to full DNS packet data in unbound python module
1933	  from Ondrej Mikle.
1934
19359 March 2012: Wouter
1936	- Applied line-buffer patch from Augie Schwer to validation.reporter.sh.
1937
19382 March 2012: Wouter
1939	- flush_infra cleans timeouted servers from the cache too.
1940	- removed warning from --enable-ecdsa.
1941
19421 March 2012: Wouter
1943	- forward-first option.  Tries without forward if a query fails.
1944	  Also stub-first option that is similar.
1945
194628 February 2012: Wouter
1947	- Fix from code review, if EINPROGRESS not defined chain if statement
1948	  differently.
1949
195027 February 2012: Wouter
1951	- Fix bug#434: on windows check registry for config file location
1952	  for unbound-control.exe, and unbound-checkconf.exe.
1953
195423 February 2012: Wouter
1955	- Fix to squelch 'network unreachable' errors from tcp connect in
1956	  logs, high verbosity will show them.
1957
195816 February 2012: Wouter
1959	- iter_hints is now thread-owned in module env, and thus threadsafe.
1960	- Fix prefetch and sticky NS, now the prefetch works.  It picks
1961	  nameservers that 'would be valid in the future', and if this makes
1962	  the NS timeout, it updates that NS by asking delegation from the
1963	  parent again.  If child NS has longer TTL, that TTL does not get
1964	  refreshed from the lookup to the child nameserver.
1965
196615 February 2012: Wouter
1967	- Fix forward-zone memory, uses malloc and frees original root dp.
1968	- iter hints (stubs) uses malloc inside for more dynamicity.
1969	- unbound-control forward_add, forward_remove, stub_add, stub_remove
1970	  can modify stubs and forwards for running unbound (on mobile computer)
1971	  they can also add and remove domain-insecure for the zone.
1972
197314 February 2012: Wouter
1974	- Fix sticky NS (ghost domain problem) if prefetch is yes.
1975	- iter forwards uses malloc inside for more dynamicity.
1976
197713 February 2012: Wouter
1978	- RT#2955. Fix for cygwin compilation.
1979	- iana portlist updated.
1980
198110 February 2012: Wouter
1982	- Slightly smaller critical region in one case in infra cache.
1983	- Fix timeouts to keep track of query type, A, AAAA and other, if
1984	  another has caused timeout blacklist, different type can still probe.
1985	- unit test fix for nomem_cnametopos.rpl race condition.
1986
19879 February 2012: Wouter
1988	- Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
1989
19908 February 2012: Wouter
1991	- implement draft-ietf-dnsext-ecdsa-04; which is in IETF LC; This
1992	  implementation is experimental at this time and not recommended
1993	  for use on the public internet (the protocol numbers have not
1994	  been assigned).  Needs recent ldns with --enable-ecdsa.
1995	- fix memory leak in errorcase for DSA signatures.
1996	- iana portlist updated.
1997	- workaround for openssl 0.9.8 ecdsa sha2 and evp problem.
1998
19993 February 2012: Wouter
2000	- fix for windows, rename() is not posix compliant on windows.
2001
20022 February 2012: Wouter
2003	- 1.4.16 release tag.
2004	- svn trunk is 1.4.17 in development.
2005	- iana portlist updated.
2006
20071 February 2012: Wouter
2008	- Fix validation failures (like: validation failure xx: no NSEC3
2009	  closest encloser from yy for DS zz. while building chain of trust,
2010	  because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
2011	  for an NSEC3.  Now it does not change rdata, and fixes TTL.
2012
201330 January 2012: Wouter
2014	- Fix version-number in libtool to be version-info so it produces
2015	  libunbound.so.2 like it should.
2016
201726 January 2012: Wouter
2018	- Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.
2019	- trunk 1.4.16; includes changes memset testcode, #424 openindiana,
2020	  and keyfile write fixup.

2022
202323 January 2012: Wouter
2024	- Fix memset in test code.
2025
202620 January 2012: Wouter
2027	- Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
2028
202919 January 2012: Wouter
2030	- Fix to write key files completely to a temporary file, and if that
2031	  succeeds, replace the real key file.  So failures leave a useful file.
2032
203318 January 2012: Wouter
2034	- tag 1.4.15rc1 created
2035	- updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
2036
203717 January 2012: Wouter
2038	- Fix bug where canonical_compare of RRSIG did not downcase the
2039	  signer-name.  This is mostly harmless because RRSIGs do not have
2040	  to be sorted in canonical order, usually.
2041
204212 January 2012: Wouter
2043	- bug#428: add ub_version() call to libunbound.  API version increase,
2044	  with (binary) backwards compatibility for the previous version.
2045
204610 January 2012: Wouter
2047	- Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
2048	  that would be permissible by the RFCs but it is not the TTL in the
2049	  cache.
2050	- iana portlist updated.
2051	- uninitialised variable in reprobe for rtt blocked domains fixed.
2052	- lintfix and new flex output.
2053
20542 January 2012: Wouter
2055	- Fix to randomize hash function, based on 28c3 congress, reported
2056	  by Peter van Dijk.
2057
205824 December 2011: Wouter
2059	- Fix for memory leak (about 20 bytes when a tcp or udp send operation
2060	  towards authority servers failed, takes about 50.000 such failures to
2061	  leak one Mb, such failures are also usually logged), reported by
2062	  Robert Fleischmann.
2063	- iana portlist updated.
2064
206519 December 2011: Wouter
2066	- Fix for VU#209659 CVE-2011-4528: Unbound denial of service
2067	  vulnerabilities from nonstandard redirection and denial of existence
2068	  http://www.unbound.net/downloads/CVE-2011-4528.txt
2069	- robust checks for next-closer NSEC3s.
2070	- tag 1.4.14 created.

2075	- Fix parse error on negative SOA RRSIGs if badly ordered in the packet.
2076
207713 December 2011: Wouter
2078	- iana portlist updated.
2079	- svn tag 1.4.14rc1
2080	- fix infra cache comparison.
2081	- Fix to constrain signer_name to be a parent of the lookupname.
2082
20835 December 2011: Wouter
2084	- Fix getaddrinfowithincludes on windows with fedora16 mingw32-gcc.

2091
209230 November 2011: Wouter
2093	- Fix for tcp-upstream and ssl-upstream for if a laptop sleeps, causes
2094	  SERVFAILs.  Also fixed for UDP (but less likely).
2095
209628 November 2011: Wouter
2097	- Fix quartile time estimate, it was too low, (thanks Jan Komissar).
2098	- iana ports updated.
2099

2102	- iana ports updated.
2103
210410 November 2011: Wouter
2105	- Makefile changed for BSD make compatibility.
2106
21079 November 2011: Wouter
2108	- added unit test for SSL service and SSL-upstream.
2109
21108 November 2011: Wouter
2111	- can configure ssl service to one port number, and not on others.
2112	- fixup windows compile with ssl support.
2113	- Fix double free in unbound-host, reported by Steve Grubb.
2114	- iana portlist updated.
2115
21161 November 2011: Wouter
2117	- dns over ssl support as a client, ssl-upstream yes turns it on.
2118	  It performs an SSL transaction for every DNS query (250 msec).
2119	- documentation for new options: ssl-upstream, ssl-service-key and
2120	  ssl-service.pem.
2121	- iana portlist updated.
2122	- fix -flto detection on Lion for llvm-gcc.
2123
212431 October 2011: Wouter
2125	- dns over ssl support, ssl-service-pem and ssl-service-key files
2126	  can be given and then TCP queries are serviced wrapped in SSL.
2127
212827 October 2011: Wouter
2129	- lame-ttl and lame-size options no longer exist, it is integrated
2130	  with the host info.  They are ignored (with verbose warning) if
2131	  encountered to keep the config file backwards compatible.
2132	- fix iana-update for changing gzip compression of results.
2133	- fix export-all-symbols on OSX.
2134
213526 October 2011: Wouter

2142	- Fix resolve of partners.extranet.microsoft.com with a fix for the
2143	  server selection for choosing out of a (particular) list of bad
2144	  choices. (bug#415)
2145	- Fix make_new_space function so that the incoming query is not
2146	  overwritten if a jostled out query causes a waiting query to be
2147	  resumed that then fails and sends an error message.  (Thanks to
2148	  Matthew Lee).
2149
215021 October 2011: Wouter
2151	- fix --enable-allsymbols, fptr wlist is disabled on windows with this
2152	  option enabled because of memory layout exe vs dll.
2153
215419 October 2011: Wouter
2155	- fix unbound-anchor for broken strptime on OSX lion, detected
2156	  in configure.

2158	- Implement ipv6%interface notation for scope_id usage.
2159
216017 October 2011: Wouter
2161	- better documentation for inform_super (Thanks Yang Zhe).
2162
216314 October 2011: Wouter
2164	- Fix for out-of-memory condition in libunbound (thanks
2165	  Robert Fleischman).
2166
216713 October 2011: Wouter
2168	- Fix --enable-allsymbols, it depended on link specifics of the
2169	  target platform, or fptr_wlist assertion failures could occur.
2170
217112 October 2011: Wouter
2172	- updated contrib/unbound_munin_ to family=auto so that it works with
2173	  munin-node-configure automatically (if installed as
2174	  /usr/local/share/munin/plugins/unbound_munin_ ).
2175
217627 September 2011: Wouter
2177	- unbound.exe -w windows option for start and stop service.
2178
217923 September 2011: Wouter
2180	- TCP-upstream calculates tcp-ping so server selection works if there
2181	  are alternatives.
2182
218320 September 2011: Wouter
2184	- Fix classification of NS set in answer section, where there is a
2185	  parent-child server, and the answer has the AA flag for dir.slb.com.
2186	  Thanks to Amanda Constant from Secure64.
2187
218816 September 2011: Wouter
2189	- fix bug #408: accept patch from Steve Snyder that comments out
2190	  unused functions in lookup3.c.
2191	- iana portlist updated.
2192	- fix EDNS1480 change memleak and TCP fallback.
2193	- fix various compiler warnings (reported by Paul Wouters).
2194	- max sent count.  EDNS1480 only for rtt < 5000.  No promiscuous
2195	  fetch if sentcount > 3, stop query if sentcount > 16.  Count is
2196	  reset when referral or CNAME happens.  This makes unbound better
2197	  at managing large NS sets, they are explored when there is continued
2198	  interest (in the form of queries).
2199
220015 September 2011: Wouter
2201	- release 1.4.13.
2202	- trunk contains 1.4.14 in development.
2203	- Unbound probes at EDNS1480 if there an EDNS0 timeout.
2204
220512 September 2011: Wouter
2206	- Reverted dns EDNS backoff fix, it did not help and needs
2207	  fragmentation fixes instead.
2208	- tag 1.4.13rc2
2209
22107 September 2011: Wouter
2211	- Fix operation in ipv6 only (do-ip4: no) mode.
2212
22136 September 2011: Wouter
2214	- fedora specfile updated.
2215
22165 September 2011: Wouter
2217	- tag 1.4.13rc1
2218
22192 September 2011: Wouter
2220	- iana portlist updated.
2221
222226 August 2011: Wouter
2223	- Fix num-threads 0 does not segfault, reported by Simon Deziel.
2224	- Fix validation failures due to EDNS backoff retries, the retry
2225	  for fetch of data has want_dnssec because the iter_indicate_dnssec
2226	  function returns true when validation failure retry happens, and
2227	  then the serviced query code does not fallback to noEDNS, even if
2228	  the cache says it has this.  This helps for DLV deployment when
2229	  the DNSSEC status is not known for sure before the lookup concludes.
2230
223124 August 2011: Wouter
2232	- Applied patch from Karel Slany that fixes a memory leak in the
2233	  unbound python module, in string conversions.
2234
223522 August 2011: Wouter
2236	- Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
2237	  Zhang and Luo Ce).  Unbound responds with the RR types that are
2238	  available at the name for qtype ANY and validates those RR types.
2239	  It does not test for completeness (i.e. with NSEC or NSEC3 query),
2240	  and it does not follow the CNAME or DNAME to another name (with
2241	  even more data for the already large response).
2242	- Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
2243	- Documented the options that work with control set_option command.
2244	- tcp-upstream yes/no option (works with set_option) for tunnels.
2245
224618 August 2011: Wouter
2247	- fix autoconf call in makedist crosscompile to RC or snapshot.
2248
224917 August 2011: Wouter
2250	- Fix validation of . DS query.
2251	- new xml format at IANA, new awk for iana_update.
2252	- iana portlist updated.
2253
225410 August 2011: Wouter
2255	- Fix python site-packages path to /usr/lib64.
2256	- updated patch from Tom.
2257	- fix memory and fd leak after out-of-memory condition.
2258
22599 August 2011: Wouter
2260	- patch from Tom Hendrikx fixes load of python modules.
2261
22628 August 2011: Wouter
2263	- make clean had ldns-src reference, removed.
2264
22651 August 2011: Wouter
2266	- Fix autoconf 2.68 warnings
2267
226814 July 2011: Wouter
2269	- Unbound implements RFC6303 (since version 1.4.7).
2270	- tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
2271	  meantime, those are for 1.4.13).
2272	- iana portlist updated.
2273
227413 July 2011: Wouter
2275	- Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
2276
227711 July 2011: Wouter
2278	- Fix wildcard expansion no-data reply under an optout NSEC3 zone is
2279	  validated as insecure, reported by Jia Li (lijia@cnnic.cn).
2280
22814 July 2011: Wouter
2282	- 1.4.12rc1 tag created.
2283
22841 July 2011: Wouter
2285	- version number in example config file.
2286	- fix that --enable-static-exe does not complain about it unknown.
2287
228830 June 2011: Wouter
2289	- tag relase 1.4.11, trunk is 1.4.12 development.
2290	- iana portlist updated.
2291	- fix bug#395: id bits of other query may leak out under conditions
2292	- fix replyaddr count wrong after jostled queries, which leads to
2293	  eventual starvation where the daemon has no replyaddrs left to use.
2294	- fix comment about rndc port, that referred to the old port number.
2295	- fix that the listening socket is not closed when too many remote
2296	  control connections are made at the same time.
2297	- removed ldns-src tarball inside the unbound tarball.
2298
229923 June 2011: Wouter
2300	- Changed -flto check to support clang compiler.
2301	- tag 1.4.11rc3 created.
2302
230317 June 2011: Wouter
2304	- tag 1.4.11rc1 created.
2305	- remove warning about signed/unsigned from flex (other flex version).
2306	- updated aclocal.m4 and libtool to match.
2307	- tag 1.4.11rc2 created.
2308
230916 June 2011: Wouter
2310	- log-queries: yesno option, default is no, prints querylog.
2311	- version is 1.4.11.
2312
231314 June 2011: Wouter
2314	- Use -flto compiler flag for link time optimization, if supported.
2315	- iana portlist updated.
2316
231712 June 2011: Wouter
2318	- IPv6 service address for d.root-servers.net (2001:500:2D::D).
2319
232010 June 2011: Wouter
2321	- unbound-control has version number in the header,
2322	  UBCT[version]_space_ is the header sent by the client now.
2323	- Unbound control port number is registered with IANA:
2324	  ub-dns-control  8953/tcp    unbound dns nameserver control
2325	  This is the new default for the control-port config setting.
2326	- statistics-interval prints the number of jostled queries to log.
2327
232830 May 2011: Wouter
2329	- Fix Makefile for U in environment, since wrong U is more common than
2330	  deansification necessity.
2331	- iana portlist updated.
2332	- updated ldns tarball to 1.6.10rc2 snapshot of today.
2333
233425 May 2011: Wouter
2335	- Fix assertion failure when unbound generates an empty error reply
2336	  in response to a query, CVE-2011-1922 VU#531342.
2337	- This fix is in tag 1.4.10.
2338	- defense in depth against the above bug, an error is printed to log
2339	  instead of an assertion failure.
2340
234110 May 2011: Wouter
2342	- bug#386: --enable-allsymbols option links all binaries to libunbound
2343	  and reduces install size significantly.
2344	- feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
2345	- iana portlist updated.
2346	- Fix TTL of SOA so negative TTL is separately cached from normal TTL.
2347
234814 April 2011: Wouter
2349	- configure created with newer autoconf 2.66.
2350
235112 April 2011: Wouter
2352	- bug#378: Fix that configure checks for ldns_get_random presence.
2353
23548 April 2011: Wouter
2355	- iana portlist updated.
2356	- queries with CD flag set cause DNSSEC validation, but the answer is
2357	  not withheld if it is bogus.  Thus, unbound will retry if it is bad
2358	  and curb the TTL if it is bad, thus protecting the cache for use by
2359	  downstream validators.
2360	- val-override-date: -1 ignores dates entirely, for NTP usage.
2361
236229 March 2011: Wouter
2363	- harden-below-nxdomain: changed so that it activates when the
2364	  cached nxdomain is dnssec secure.  This avoids backwards
2365	  incompatibility because those old servers do not have dnssec.
2366
236724 March 2011: Wouter
2368	- iana portlist updated.
2369	- release 1.4.9.
2370	- trunk is 1.5.0
2371
237217 March 2011: Wouter
2373	- bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
2374	  Applied but did not do the --disable-gost.
2375
237610 March 2011: Wouter
2377	- tag 1.4.9 release candidate 1 created.
2378

2404	- tpkg updated with common.sh for common functionality.
2405
24067 February 2011: Wouter
2407	- Added regression test for addition of a .net DS to the root, and
2408	  cache effects with different TTL for glue and DNSKEY.
2409	- iana portlist updated.
2410

2426	- iana portlist updated.
2427
242814 January 2011: Wouter
2429	- Fix so a changed NS RRset does not get moved name stuck on old
2430	  server, for type NS the TTL is not increased.
2431
243213 January 2011: Wouter
2433	- Fix prefetch so it does not get stuck on old server for moved names.
2434
243512 January 2011: Wouter
2436	- iana portlist updated.
2437

2450	- Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
2451
245221 December 2010: Wouter
2453	- algorithm compromise protection using the algorithms signalled in
2454	  the DS record.  Also, trust anchors, DLV, and RFC5011 receive this,
2455	  and thus, if you have multiple algorithms in your trust-anchor-file
2456	  then it will now behave different than before.  Also, 5011 rollover
2457	  for algorithms needs to be double-signature until the old algorithm
2458	  is revoked.
2459	  It is not an option, because I see no use to turn the security off.
2460	- iana portlist updated.
2461
246217 December 2010: Wouter
2463	- squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
2464	- fix validation in this case: CNAME to nodata for co-hosted opt-in
2465	  NSEC3 insecure delegation, was bogus, fixed to be insecure.
2466
246716 December 2010: Wouter
2468	- Fix our 'BDS' license (typo reported by Xavier Belanger).
2469
247010 December 2010: Wouter
2471	- iana portlist updated.
2472	- review changes for unbound-anchor.
2473
24742 December 2010: Wouter
2475	- feature typetransparent localzone, does not block other RR types.
2476

2478	- Fix bug#338: print address when socket creation fails.
2479
248030 November 2010: Wouter
2481	- Fix storage of EDNS failures in the infra cache.
2482	- iana portlist updated.
2483
248418 November 2010: Wouter
2485	- harden-below-nxdomain option, default off (because very old
2486	  software may be incompatible).  We could enable it by default in
2487	  the future.
2488
248917 November 2010: Wouter
2490	- implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
2491	- make test output nicer.
2492
249315 November 2010: Wouter
2494	- silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
2495	- iana portlist updated.
2496	- so-sndbuf option for very busy servers, a bit like so-rcvbuf.
2497
24989 November 2010: Wouter
2499	- unbound-anchor compiles with openssl 0.9.7.
2500
25018 November 2010: Wouter
2502	- release tag 1.4.7.
2503	- trunk is version 1.4.8.
2504	- Be lenient and accept imgw.pl malformed packet (like BIND).
2505
25065 November 2010: Wouter
2507	- do not synthesize a CNAME message from cache for qtype DS.
2508
25094 November 2010: Wouter
2510	- Use central entropy to seed threads.
2511
25123 November 2010: Wouter
2513	- Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
2514
25152 November 2010: Wouter

2517	- code review.
2518
25191 November 2010: Wouter

2521
252227 October 2010: Wouter
2523	- Fix uninit value in dump_infra print.
2524	- Fix validation failure for parent and child on same server with an
2525	  insecure childzone and a CNAME from parent to child.
2526	- Configure detects libev-4.00.
2527
252826 October 2010: Wouter
2529	- dump_infra and flush_infra commands for unbound-control.
2530	- no timeout backoff if meanwhile a query succeeded.
2531	- Change of timeout code.  No more lost and backoff in blockage.
2532	  At 12sec timeout (and at least 2x lost before) one probe per IP
2533	  is allowed only.  At 120sec, the IP is blocked.  After 15min, a
2534	  120sec entry has a single retry packet.
2535
253625 October 2010: Wouter
2537	- Configure errors if ldns is not found.
2538
253922 October 2010: Wouter
2540	- Windows 7 fix for the installer.
2541
254221 October 2010: Wouter
2543	- Fix bug where fallback_tcp causes wrong roundtrip and edns
2544	  observation to be noted in cache.  Fix bug where EDNSprobe halted
2545	  exponential backoff if EDNS status unknown.
2546	- new unresponsive host method, exponentially increasing block backoff.
2547	- iana portlist updated.
2548
254920 October 2010: Wouter
2550	- interface automatic works for some people with ip6 disabled.
2551	  Therefore the error check is removed, so they can use the option.
2552
255319 October 2010: Wouter
2554	- Fix for request list growth, if a server has long timeout but the
2555	  lost counter is low, then its effective rtt is the one without
2556	  exponential backoff applied.  Because the backoff is not working.
2557	  The lost counter can then increase and the server is blacklisted,
2558	  or the lost counter does not increase and the server is working
2559	  for some queries.
2560
256118 October 2010: Wouter
2562	- iana portlist updated.
2563
256413 October 2010: Wouter
2565	- Fix TCP so it uses a random outgoing-interface.
2566	- unbound-anchor handles ADDPEND keystate.
2567
256811 October 2010: Wouter
2569	- Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
2570	  the zone has a secure delegation hosted on the same server did not
2571	  verify as secure (it was insecure by mistake).
2572	- iana portlist updated.
2573	- ldns tarball updated (for reading cachedumps with bad RR data).
2574
25751 October 2010: Wouter
2576	- test for unbound-anchor. fix for reading certs.
2577	- Fix alloc_reg_release for longer uptime in out of memory conditions.
2578
257928 September 2010: Wouter
2580	- unbound-anchor working, it creates or updates a root.key file.
2581	  Use it before you start the validator (e.g. at system boot time).

2584	- iana portlist updated.
2585
258624 September 2010: Wouter

2588
258923 September 2010: Wouter
2590	- unbound-anchor app, unbound requires libexpat (xml parser library).
2591
259222 September 2010: Wouter
2593	- compliance with draft-ietf-dnsop-default-local-zones-14, removed
2594	  reverse ipv6 orchid prefix from builtin list.

2598	- DLV has downgrade protection again, because the RFC says so.
2599	- iana portlist updated.
2600
260116 September 2010: Wouter
2602	- Algorithm rollover operational reality intrudes, for trust-anchor,
2603	  5011-store, and DLV-anchor if one key matches it's good enough.
2604	- iana portlist updated.
2605	- Fix reported validation error in out of memory condition.
2606
260715 September 2010: Wouter
2608	- Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
2609
261014 September 2010: Wouter
2611	- increased mesh-max-activation from 1000 to 3000 for crazy domains
2612	  like _tcp.slb.com with 262 servers.
2613	- iana portlist updated.
2614
261513 September 2010: Wouter
2616	- bug#327: Fix for cannot access stub zones until the root is primed.
2617
26189 September 2010: Wouter
2619	- unresponsive servers are not completely blacklisted (because of
2620	  firewalls), but also not probed all the time (because of the request
2621	  list size it generates).  The probe rate is 1%.
2622	- iana portlist updated.
2623
262420 August 2010: Wouter
2625	- openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
2626	  iterator get_mem includes priv_get_mem.  delegpt nodup removed.

2640	  if use sun-cc, but some systems need different flags.
2641
264216 August 2010: Wouter
2643	- Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
2644	  changes, uses m4_bpatsubst now.
2645	- make test (or make check) should be more portable and run the unit
2646	  test and testbound scripts. (make longtest has special requirements).
2647
264813 August 2010: Wouter
2649	- More pleasant remote control command parsing.
2650	- documentation added for return values reported by doxygen 1.7.1.
2651	- iana portlist updated.
2652

2665	- release tag 1.4.6.
2666	- trunk becomes 1.4.7 develop.
2667	- iana portlist updated.
2668
266922 July 2010: Wouter
2670	- more error details on failed remote control connection.
2671
267215 July 2010: Wouter
2673	- rlimit adjustments for select and ulimit can happen at the same time.
2674
267514 July 2010: Wouter
2676	- Donation text added to README.
2677	- Fix integer underflow in prefetch ttl creation from cache.  This
2678	  fixes a potential negative prefetch ttl.
2679
268012 July 2010: Wouter
2681	- Changed the defaults for num-queries-per-thread/outgoing-range.
2682	  For builtin-select: 512/960, for libevent 1024/4096 and for
2683	  windows 24/48 (because of win api).  This makes the ratio this way
2684	  to improve resilience under heavy load.  For high performance, use
2685	  libevent and possibly higher numbers.
2686
268710 July 2010: Wouter
2688	- GOST enabled if SSL is recent and ldns has GOST enabled too.
2689	- ldns tarball updated.
2690
26919 July 2010: Wouter
2692	- iana portlist updated.
2693	- Fix validation of qtype DNSKEY when a key-cache entry exists but
2694	  no rr-cache entry is used (it expired or prefetch), it then goes
2695	  back up to the DS or trust-anchor to validate the DNSKEY.
2696
26977 July 2010: Wouter
2698	- Neat function prototypes, unshadowed local declarations.
2699
27006 July 2010: Wouter
2701	- failure to chown the pidfile is not fatal any more.
2702	- testbound uses UTC timezone.
2703	- ldns tarball updated (ports and works on Minix 3.1.7).  On Minix, add
2704	  /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
2705
27065 July 2010: Wouter
2707	- log if a server is skipped because it is on the donotquery list,
2708	  at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
2709	- added feature to print configure date, target and options with -h.
2710	- added feature to print event backend system details with -h.
2711	- wdiff is not actually required by make test, updated requirements.
2712
27131 July 2010: Wouter
2714	- Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
2715	  must be signed with all algorithms from the DS rrset at the parent.
2716	  This is now checked and becomes bogus if not.
2717
271828 June 2010: Wouter
2719	- Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
2720	  in overload situations to be about 5 qps for the class of shortly
2721	  serviced queries.
2722	  The capacity of the resolver is then about (numqueriesperthread / 2)
2723	  / (average time for such long queries) qps for long queries.
2724	  And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
2725	  qps for short queries, per thread.
2726	- Fix the max number of reply-address count to be applied for duplicate
2727	  queries, and not for new query list entries.  This raises the memory
2728	  usage to a max of (16+1)*numqueriesperthread reply addresses.
2729
273025 June 2010: Wouter
2731	- Fix handling of corner case reply from lame server, follows rfc2308.
2732	  It could lead to a nodata reply getting into the cache if the search
2733	  for a non-lame server turned up other misconfigured servers.
2734	- unbound.h has extern "C" statement for easier include in c++.
2735
273623 June 2010: Wouter
2737	- iana portlist updated.
2738	- makedist upgraded cross compile openssl option, like this:

2747
274817 June 2010: Wouter
2749	- Add AAAA to root hints for I.ROOT-SERVERS.NET.
2750
275116 June 2010: Wouter
2752	- Fix assertion failure reported by Kai Storbeck from XS4ALL, the
2753	  assertion was wrong.
2754	- updated ldns tarball.
2755
275615 June 2010: Wouter
2757	- tag 1.4.5 created.
2758	- trunk contains 1.4.6 in development.
2759	- Fix TCPreply on systems with no writev, if just 1 byte could be sent.
2760	- Fix to use one pointer less for iterator query state store_parent_NS.
2761	- makedist crosscompile to windows uses builtin ldns not host ldns.
2762	- Max referral count from 30 to 130, because 128 one character domains
2763	  is valid DNS.
2764	- added documentation for the histogram printout to syslog.
2765
276611 June 2010: Wouter
2767	- When retry to parent the retrycount is not wiped, so failed
2768	  nameservers are not tried again.
2769	- iana portlist updated.
2770
277110 June 2010: Wouter
2772	- Fix bug where a long loop could be entered, now cycle detection
2773	  has a loop-counter and maximum search amount.
2774
27754 June 2010: Wouter
2776	- iana portlist updated.
2777	- 1.4.5rc1 tag created.
2778
27793 June 2010: Wouter
2780	- ldns tarball updated, 1.6.5.
2781	- review comments, split dependency cycle tracking for parentside
2782	  last resort lookups for A and AAAA so there are more lookup options.
2783
27842 June 2010: Wouter
2785	- Fix compile warning if compiled without threads.
2786	- updated ldns-tarball with current ldns svn (pre 1.6.5).
2787	- GOST disabled-by-default, the algorithm number is allocated but the
2788	  RFC is still has to pass AUTH48 at the IETF.
2789
27901 June 2010: Wouter
2791	- Ignore Z flag in incoming messages too.
2792	- Fix storage of negative parent glue if that last resort fails.
2793	- libtoolize 2.2.6b, autoconf 2.65 applied to configure.
2794	- new splint flags for newer splint install.
2795
279631 May 2010: Wouter
2797	- Fix AD flag handling, it could in some cases mistakenly copy the AD
2798	  flag from upstream servers.
2799	- alloc_special_obtain out of memory is not a fatal error any more,
2800	  enabling unbound to continue longer in out of memory conditions.
2801	- parentside names are dispreferred but not said to be dnssec-lame.
2802	- parentside check for cached newname glue.
2803	- fix parentside and querytargets modulestate, for dump_requestlist.
2804	- unbound-control-setup makes keys -rw-r--- so not all users permitted.
2805	- fix parentside from cache to be marked dispreferred for bad names.
2806
280728 May 2010: Wouter
2808	- iana portlist updated.
2809	- parent-child disagreement approach altered.  Older fixes are
2810	  removed in place of a more exhaustive search for misconfigured data
2811	  available via the parent of a delegation.
2812	  This is designed to be throttled by cache entries, with TTL from the
2813	  parent if possible.  Additionally the loop-counter is used.
2814	  It also tests for NS RRset differences between parent and child.
2815	  The fetch of misconfigured data should be more reliable and thorough.
2816	  It should work reliably even with no or only partial data in cache.
2817	  Data received from the child (as always) is deemed more
2818	  authoritative than information received from the delegation parent.
2819	  The search for misconfigured data is not performed normally.
2820
282126 May 2010: Wouter
2822	- Contribution from Migiel de Vos (Surfnet): nagios patch for
2823	  unbound-host, in contrib/ (in the source tarball).  Makes
2824	  unbound-host suitable for monitoring dnssec(-chain) status.
2825
282621 May 2010: Wouter
2827	- EDNS timeout code will not fire if EDNS status already known.
2828	- EDNS failure not stored if EDNS status known to work.
2829
283019 May 2010: Wouter
2831	- Fix resolution for domains like safesvc.com.cn.  If the iterator
2832	  can not recurse further and it finds the delegation in a state
2833	  where it would otherwise have rejected it outhand if so received
2834	  from a cache lookup, then it can try to ask higherup (with loop
2835	  protection).
2836	- Fix comments in iter_utils:dp_is_useless.
2837
283818 May 2010: Wouter
2839	- Fix various compiler warnings from the clang llvm compiler.
2840	- iana portlist updated.
2841
28426 May 2010: Wouter
2843	- Fix bug#308: spelling error in variable name in parser and lexer.
2844
28454 May 2010: Wouter
2846	- Fix dnssec-missing detection that was turned off by server selection.
2847	- Conforms to draft-ietf-dnsop-default-local-zones-13.  Added default
2848	  reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
2849	  113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
2850
285129 April 2010: Wouter
2852	- Fix for dnssec lameness detection to use the key cache.
2853	- infra cache entries that are expired are wiped clean.  Previously
2854	  it was possible to not expire host data (if accessed often).
2855
285628 April 2010: Wouter
2857	- ldns tarball updated and GOST support is detected and then enabled.
2858	- iana portlist updated.
2859	- Fix detection of gost support in ldns (reported by Chris Smith).
2860
286127 April 2010: Wouter
2862	- unbound-control get_option domain-insecure shows config file items.
2863	- fix retry sequence if prime hints are recursion-lame.
2864	- autotrust anchor file can be initialized with a ZSK key as well.
2865	- harden-referral-path does not result in failures due to max-depth.
2866	  You can increase the max-depth by adding numbers (' 0') after the
2867	  target-fetch-policy, this increases the depth to which is checked.
2868
286926 April 2010: Wouter
2870	- Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
2871	  CPPFLAGS during configure process.
2872	- if libev is installed on the base system (not libevent), detect
2873	  it from the event.h header file and link with -lev.
2874	- configlexer.lex gets config.h, and configyyrename.h added by make,
2875	  no more double include.
2876	- More strict scrubber (Thanks to George Barwood for the idea):
2877	  NS set must be pertinent to the query (qname subdomain nsname).
2878	- Fix bug#307: In 0x20 backoff fix fallback so the number of
2879	  outstanding queries does not become -1 and block the request.
2880	  Fixed handling of recursion-lame in combination with 0x20 fallback.
2881	  Fix so RRsets are compared canonicalized and sorted if the immediate
2882	  comparison fails, this makes it work around round-robin sites.
2883
288423 April 2010: Wouter
2885	- Squelch log message: sendto failed permission denied for
2886	  255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
2887	- Fix to fetch data as last resort more tenaciously.  When cycle
2888	  targets cause the server selection to believe there are more options
2889	  when they really are not there, the server selection is reinitiated.
2890	- Fix fetch from blacklisted dnssec lame servers as last resort.  The
2891	  server's IP address is then given in validator errors as well.
2892	- Fix local-zone type redirect that did not use the query name for
2893	  the answer rrset.
2894
289522 April 2010: Wouter
2896	- tag 1.4.4.
2897	- trunk contains 1.4.5 in development.
2898	- Fix validation failure for qtype ANY caused by a RRSIG parse failure.
2899	  The validator error message was 'no signatures from ...'.
2900
290116 April 2010: Wouter
2902	- more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
2903	- tag 1.4.4rc1.
2904
290515 April 2010: Wouter
2906	- ECC-GOST algorithm number 12 that is assigned by IANA.  New test
2907	  example key and signatures for GOST.  GOST requires openssl-1.0.0.
2908	  GOST is still disabled by default.
2909
29109 April 2010: Wouter
2911	- Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
2912	  get into an endless loop, if 0x20 was enabled, and buffers are small
2913	  or particular broken packets are received.
2914	- Fix chain of trust with CNAME at an intermediate step, for the DS
2915	  processing proof.
2916
29178 April 2010: Wouter
2918	- Fix validation of queries with wildcard names (*.example).
2919
29206 April 2010: Wouter
2921	- Fix EDNS probe for .de DNSSEC testbed failure, where the infra
2922	  cache timeout coincided with a server update, the current EDNS
2923	  backoff is less sensitive, and does not cache the backoff unless
2924	  the backoff actually works and the domain is not expecting DNSSEC.
2925	- GOST support with correct algorithm numbers.
2926
29271 April 2010: Wouter
2928	- iana portlist updated.
2929
293024 March 2010: Wouter
2931	- unbound control flushed items are not counted when flushed again.
2932
293323 March 2010: Wouter
2934	- iana portlist updated.
2935
293622 March 2010: Wouter
2937	- unbound-host disables use-syslog from config file so that the
2938	  config file for the main server can be used more easily.
2939	- fix bug#301: unbound-checkconf could not parse interface
2940	  '0.0.0.0@5353', even though unbound itself worked fine.
2941
294219 March 2010: Wouter
2943	- fix fwd_ancil test to pass if the socket options are not supported.
2944
294518 March 2010: Wouter
2946	- Fixed random numbers for port, interface and server selection.
2947	  Removed very small bias.
2948	- Refer to the listing in unbound-control man page in the extended
2949	  statistics entry in the unbound.conf man page.
2950
295116 March 2010: Wouter
2952	- Fix interface-automatic for OpenBSD: msg.controllen was too small,
2953	  also assertions on ancillary data buffer.
2954	- check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
2955	- for NSEC3 check if signatures are cached.
2956
295715 March 2010: Wouter
2958	- unit test for util/regional.c.
2959
296012 March 2010: Wouter
2961	- Reordered configure checks so fork and -lnsl -lsocket checks are
2962	  earlier, and thus later checks benefit from and do not hinder them.
2963	- iana portlist updated.
2964	- ldns tarball updated.
2965	- Fix python use when multithreaded.
2966	- Fix solaris python compile.
2967	- Include less in config.h and include per code file for ldns, ssl.
2968
296911 March 2010: Wouter
2970	- another memory allocation option: --enable-alloc-nonregional.
2971	  exposes the regional allocations to other memory purifiers.
2972	- fix for memory alignment in struct sock_list allocation.
2973	- Fix for MacPorts ldns without ssl default, unbound checks if ldns
2974	  has dnssec functionality and uses the builtin if not.
2975	- Fix daemonize on Solaris 10, it did not detach from terminal.
2976	- tag 1.4.3 created.
2977	- trunk is 1.4.4 in development.
2978	- spelling fix in validation error involving cnames.
2979
298010 March 2010: Wouter
2981	- --enable-alloc-lite works with test set.
2982	- portability in the testset: printf format conversions, prototypes.
2983
29849 March 2010: Wouter
2985	- tag 1.4.2 created.
2986	- trunk is 1.4.3 in development.
2987	- --enable-alloc-lite debug option.
2988
29898 March 2010: Wouter
2990	- iana portlist updated.
2991
29924 March 2010: Wouter
2993	- Fix crash in control channel code.
2994
29953 March 2010: Wouter
2996	- better casts in pipe code, brackets placed wrongly.
2997	- iana portlist updated.
2998
29991 March 2010: Wouter
3000	- make install depends on make all.
3001	- Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
3002	- --enable-checking: enables assertions but does not look nonproduction.
3003	- nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
3004	  nxdomain and nodata distinguished.
3005	- ldns tarball updated.
3006	- --disable-rpath fixed for libtool not found errors.
3007	- new fedora specfile from Fedora13 in contrib from Paul Wouters.
3008
300926 February 2010: Wouter
3010	- Fixup prototype for lexer cleanup in daemon code.
3011	- unbound-control list_stubs, list_forwards, list_local_zones and
3012	  list_local_data.
3013
301424 February 2010: Wouter
3015	- Fix scrubber bug that potentially let NS records through.  Reported
3016	  by Amanda Constant.
3017	- Also delete potential poison references from additional.
3018	- Fix: no classification of a forwarder as lame, throw away instead.
3019
302023 February 2010: Wouter
3021	- libunbound ub_ctx_get_option() added.
3022	- unbound-control set_option and get_option commands.
3023	- iana portlist updated.
3024
302518 February 2010: Wouter
3026	- A little more strict DS scrubbing.
3027	- No more blacklisting of unresponsive servers, a 2 minute timeout
3028	  is backed off to.
3029	- RD flag not enabled for dnssec-blacklisted tries, unless necessary.
3030	- pickup ldns compile fix, libdl for libcrypto.
3031	- log 'tcp connect: connection timed out' only in high verbosity.
3032	- unbound-control log_reopen command.
3033	- moved get_option code from unbound-checkconf to util/config_file.c
3034
303517 February 2010: Wouter
3036	- Disregard DNSKEY from authority section for chain of trust.
3037	  DS records that are irrelevant to a referral scrubbed.  Anti-poison.
3038	- iana portlist updated.
3039
304016 February 2010: Wouter
3041	- Check for 'no space left on device' (or other errors) when
3042	  writing updated autotrust anchors and print errno to log.
3043
304415 February 2010: Wouter
3045	- Fixed the requery protection, the TTL was 0, it is now 900 seconds,
3046	  hardcoded.  We made the choice to send out more conservatively,
3047	  protecting against an aggregate effect more than protecting a
3048	  single user (from their own folly, perhaps in case of misconfig).
3049
305012 February 2010: Wouter
3051	- Re-query pattern changed on validation failure.  To protect troubled
3052	  authority servers, unbound caches a failure for the DNSKEY or DS
3053	  records for the entire zone, and only retries that 900 seconds later.
3054	  This implies that only a handful of packets are sent extra to the
3055	  authority if the zone fails.
3056
305711 February 2010: Wouter
3058	- ldns tarball update for long label length syntax error fix.
3059	- iana portlist updated.
3060
30619 February 2010: Wouter
3062	- Fixup in compat snprintf routine, %f 1.02 and %g support.
3063	- include math.h for testbound test compile portability.
3064
30652 February 2010: Wouter
3066	- Updated url of IANA itar, interim trust anchor repository, in script.
3067
30681 February 2010: Wouter
3069	- iana portlist updated.
3070	- configure test for memcmp portability.
3071
307227 January 2010: Wouter
3073	- removed warning on format string in validator error log statement.
3074	- iana portlist updated.
3075
307622 January 2010: Wouter
3077	- libtool finish the install of unbound python dynamic library.
3078
307921 January 2010: Wouter
3080	- acx_nlnetlabs.m4 synchronised with nsd's version.
3081
308220 January 2010: Wouter
3083	- Fixup lookup trouble for parent-child domains on the first query.
3084
308514 January 2010: Wouter
3086	- Fixup ldns detection to also check for header files.
3087
308813 January 2010: Wouter
3089	- prefetch-key option that performs DNSKEY queries earlier in the
3090	  validation process, and that could halve the latency on DNSSEC
3091	  queries.  It takes some extra processing (CPU, a cache is needed).
3092
309312 January 2010: Wouter
3094	- Fix unbound-checkconf for auto-trust-anchor-file present checks.
3095
30968 January 2010: Wouter
3097	- Fix for parent-child disagreement code which could have trouble
3098	  when (a) ipv6 was disabled and (b) the TTL for parent and child
3099	  were different.  There were two bugs, the parent-side information
3100	  is fixed to no longer block lookup of child side information and
3101	  the iterator is fixed to no longer attempt to get ipv6 when it is
3102	  not enabled and then give up in failure.
3103	- test and fixes to make prefetch actually store the answer in the
3104	  cache.  Considers some rrsets 'already expired' but does not allow
3105	  overwriting of rrsets considered more secure.
3106
31077 January 2010: Wouter
3108	- Fixup python documentation (thanks Leo Vandewoestijne).
3109	- Work on cache prefetch feature.
3110	- Stats for prefetch, in log print stats, unbound-control stats
3111	  and in unbound_munin plugin.
3112
31136 January 2010: Wouter
3114	- iana portlist updated.
3115	- bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.
3116	- verbose output includes parent-side-address notion for lameness.
3117	- documented val-log-level: 2 setting in example.conf and man page.
3118	- change unbound-control-setup from 1024(sha1) to 1536(sha256).
3119
31201 January 2010: Wouter
3121	- iana portlist updated.
3122
312322 December 2009: Wouter
3124	- configure with newer libtool 2.2.6b.
3125
312617 December 2009: Wouter
3127	- review comments.
3128	- tag 1.4.1.
3129	- trunk to version 1.4.2.
3130
313115 December 2009: Wouter
3132	- Answer to qclass=ANY queries, with class IN contents.
3133	  Test that validation also works.
3134	- updated ldns snapshot tarball with latest fixes (parsing records).
3135
313611 December 2009: Wouter
3137	- on IPv4 UDP turn off DF flag.
3138
313910 December 2009: Wouter
3140	- requirements.txt updated with design choice explanations.
3141	- Reading fixes: fix to set unlame when child confirms parent glue,
3142	  and fix to avoid duplicate addresses in delegation point.
3143	- verify_rrsig routine checks expiration last.
3144
31459 December 2009: Wouter
3146	- Fix Bug#287(reopened): update of ldns tarball with fix for parse
3147	  errors generated for domain names like '.example.com'.
3148	- Fix SOA excluded from negative DS responses.  Reported by Hauke
3149	  Lampe.  The negative cache did not include proper SOA records for
3150	  negative qtype DS responses which makes BIND barf on it, such
3151	  responses are now only used internally.
3152	- Fix negative cache lookup of closestencloser check of DS type bit.
3153
31548 December 2009: Wouter
3155	- Fix for lookup of parent-child disagreement domains, where the
3156	  parent-side glue works but it does not provide proper NS, A or AAAA
3157	  for itself, fixing domains such as motorcaravanners.eu.
3158	- Feature: you can specify a port number in the interface: line, so
3159	  you can bind the same interface multiple times at different ports.
3160
31617 December 2009: Wouter
3162	- Bug#287: Fix segfault when unbound-control remove nonexistent local
3163	  data.  Added check to tests.
3164
31651 December 2009: Wouter
3166	- Fix crash with module-config "iterator".
3167	- Added unit test that has "iterator" module-config.
3168
316930 November 2009: Wouter
3170	- bug#284: fix parse of # without end-of-line at end-of-file.
3171
317226 November 2009: Wouter
3173	- updated ldns with release candidate for version 1.6.3.
3174	- tag for 1.4.0 release.
3175	- 1.4.1 version in trunk.
3176	- Fixup major libtool version to 2 because of why_bogus change.
3177	  It was 1:5:0 but should have been 2:0:0.
3178
317923 November 2009: Wouter
3180	- Patch from David Hubbard for libunbound manual page.
3181	- Fixup endless spinning in unbound-control stats reported by
3182	  Attila Nagy.  Probably caused by clock reversal.
3183
318420 November 2009: Wouter
3185	- contrib/split-itar.sh contributed by Tom Hendrikx.
3186
318719 November 2009: Wouter
3188	- better argument help for unbound-control.
3189	- iana portlist updated.
3190
319117 November 2009: Wouter
3192	- noted multiple entries for multiple domain names in example.conf.
3193	- iana portlist updated.
3194
319516 November 2009: Wouter
3196	- Fixed signer detection of CNAME responses without signatures.
3197	- Fix#282 libunbound memleak on error condition by Eric Sesterhenn.
3198	- Tests for CNAMEs to deeper trust anchors, secure and bogus.
3199	- svn tag 1.4.0rc1 made.
3200
320113 November 2009: Wouter
3202	- Fixed validation failure for CNAME to optout NSEC3 nodata answer.
3203	- unbound-host does not fail on type ANY.
3204	- Fixed wireparse failure to put RRSIGs together with data in some
3205	  long ANY mix cases, which fixes validation failures.
3206
320712 November 2009: Wouter
3208	- iana portlist updated.
3209	- fix manpage errors reported by debian lintian.
3210	- review comments.
3211	- fixup very long vallog2 level error strings.
3212
321311 November 2009: Wouter
3214	- ldns tarball updated (to 1.6.2).
3215	- review comments.
3216
321710 November 2009: Wouter
3218	- Thanks to Surfnet found bug in new dnssec-retry code that failed
3219	  to combine well when combined with DLV and a particular failure.
3220	- Fixed unbound-control -h output about argument optionality.
3221	- review comments.
3222
32235 November 2009: Wouter
3224	- lint fixes and portability tests.
3225	- better error text for multiple domain keys in one autotrust file.
3226
32272 November 2009: Wouter
3228	- Fix bug where autotrust does not work when started with a DS.
3229	- Updated GOST unit tests for unofficial algorithm number 249
3230	  and DNSKEY-format changes in draft version -01.
3231
323229 October 2009: Wouter
3233	- iana portlist updated.
3234	- edns-buffer-size option, default 4096.
3235	- fixed do-udp: no.
3236
323728 October 2009: Wouter
3238	- removed abort on prealloc failure, error still printed but softfail.
3239	- iana portlist updated.
3240	- RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
3241	- ldns tarball updated (which also enables rsasha256 support).
3242
324327 October 2009: Wouter
3244	- iana portlist updated.
3245
32468 October 2009: Wouter
3247	- please doxygen
3248	- add val-log-level print to corner case (nameserver.epost.bg).
3249	- more detail to errors from insecure delegation checks.
3250	- Fix double time subtraction in negative cache reported by
3251	  Amanda Constant and Hugh Mahon.
3252	- Made new validator error string available from libunbound for
3253	  applications.  It is in result->why_bogus, a zero-terminated string.
3254	  unbound-host prints it by default if a result is bogus.
3255	  Also the errinf is public in module_qstate (for other modules).
3256
32577 October 2009: Wouter
3258	- retry for validation failure in DS and prime results. Less mem use.
3259	  unit test.  Provisioning in other tests for requeries.
3260	- retry for validation failure in DNSKEY in middle of chain of trust.
3261	  unit test.
3262	- retry for empty non terminals in chain of trust and unit test.
3263	- Fixed security bug where the signatures for NSEC3 records were not
3264	  checked when checking for absence of DS records.  This could have
3265	  enabled the substitution of an insecure delegation.
3266	- moved version number to 1.4.0 because of 1.3.4 release with only
3267	  the NSEC3 patch from the entry above.
3268	- val-log-level: 2 shows extended error information for validation
3269	  failures, but still one (longish) line per failure.  For example:
3270	  validation failure <example.com. DNSKEY IN>: signature expired from
3271	  192.0.2.4 for trust anchor example.com. while building chain of trust
3272	  validation failure <www.example.com. A IN>: no signatures from
3273	  192.0.2.6 for key example.com. while building chain of trust
3274
32756 October 2009: Wouter
3276	- Test set updated to provide additional ns lookup result.
3277	  The retry would attempt to fetch the data from other nameservers
3278	  for bogus data, and this needed to be provisioned in the tests.
3279
32805 October 2009: Wouter
3281	- first validation failure retry code.  Retries for data failures.
3282	  And unit test.
3283
32842 October 2009: Wouter
3285	- improve 5011 modularization.
3286	- fix unbound-host so -d can be given before -C.
3287	- iana portlist updated.

3304	- test unbound reading of original autotrust data.
3305	  The metadata per-key, such as key state (PENDING, MISSING, VALID) is
3306	  picked up, otherwise performs initial probe like usual.

330822 September 2009: Wouter
3309	- autotrust test with algorithm rollover, new ordering of checks
3310	  assists in orderly rollover.

3335	- increased MAXSYSLOGLEN so .bg key can be printed in debug output.
3336	- use linebuffering for log-file: output, this can be significantly
3337	  faster than the previous fflush method and enable some class of
3338	  resolvers to use high verbosity (for short periods).
3339	  Not on windows, because line buffering does not work there.
3340
33419 September 2009: Wouter
3342	- Fix bug where DNSSEC-bogus messages were marked with too high TTL.
3343	  The RRsets would still expire at the normal time, but this would

3562	  structures so that later validation would fail.
3563	- Extreme lenience for wrongly truncated replies where a positive
3564	  reply has an NS in the authority but no signatures.  They are
3565	  turned into minimal responses with only the (secure) answer.
3566	- autoconf 2.63 for configure.
3567	- python warnings suppress.  Keep python API away from header files.

3579	  has to be reexamined.
3580
358115 June 2009: Wouter
3582	- iana portlist updated.
3583
358414 June 2009: Wouter

3596	- fwd above stub in configuration works.
3597
359811 June 2009: Wouter
3599	- Fix queries for type DS when forward or stub zones are there.
3600	  They are performed to higherup domains, and thus treated as if
3601	  going to higher zones when looking up the right forward or stub
3602	  server.  This makes a stub pointing to a local server that has
3603	  a local view of example.com signed with the same keys as are
3604	  publicly used work.  Reported by Johan Ihren.
3605	- Added build-unbound-localzone-from-hosts.pl to contrib, from
3606	  Dennis DeDonatis.  It converts /etc/hosts into config statements.
3607	- same thing fixed for forward-zone and DS, chain of trust from
3608	  public internet into the forward-zone works now.  Added unit test.
3609
36109 June 2009: Wouter
3611	- openssl key files are opened apache-style, when user is root and
3612	  before chrooting.  This makes permissions on remote-control key
3613	  files easier to set up.  Fixes bug #251.
3614	- flush_type and flush_name remove msg cache entries.
3615	- codereview - dp copy bogus setting fix.
3616
36178 June 2009: Wouter
3618	- Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
3619	  inadvertant behaviour.
3620	- 1.3.0 tarball for release created.
3621	- 1.3.1 development in svn trunk.

3630	  Reported by Paul Wouters.
3631	- review comments from Matthijs.
3632
36332 June 2009: Wouter
3634	- --enable-sha2 option. The draft rsasha256 changed its algorithm
3635	  numbers too often.  Therefore it is more prudent to disable the
3636	  RSASHA256 and RSASHA512 support by default.
3637	- ldns trunk included as new tarball.
3638	- recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.

3646
364727 May 2009: Wouter
3648	- detect lack of IPv6 support on XP (with a different error code).
3649	- Fixup a crash-on-exit which was triggered by a very long queue.
3650	  Unbound would try to re-use ports that came free, but this is
3651	  of course not really possible because everything is deleted.
3652	  Most easily triggered on XP (not Vista), maybe because of the
3653	  network stack encouraging large messages backlogs.
3654	- change in debug statements.
3655	- Fixed bug that could cause a crash if root prime failed when there
3656	  were message backlogs.
3657
365826 May 2009: Wouter
3659	- Thanks again to Brett Carr, found an assertion that was not true.

3661
366229 April 2009: Wouter
3663	- Thanks to Brett Carr, caught windows resource leak, use
3664	  closesocket() and not close() on sockets or else the network stack
3665	  starts to leak handles.
3666	- Removed usage of windows Mutex because windows cannot handle enough
3667	  mutexes open.  Provide own mutex implementation using primitives.
3668
366928 April 2009: Wouter
3670	- created svn tag for 1.3.0.

3712	- ldns tarball updated.
3713	- iana portlist update.
3714	- detect GOST support in openssl-1.0.0-beta1, and fix compile problem
3715	  because that openssl defines the name STRING for itself.
3716
37176 April 2009: Wouter
3718	- windows compile fix.
3719	- Detect FreeBSD jail without ipv6 addresses assigned.
3720	- python libunbound wrapper unit test.

3723	  /usr/lib/python2.x/site-packages/unboundmodule.py
3724	  	from configure --with-pyunbound:
3725	  /usr/lib/python2.x/site-packages/unbound.py
3726	  /usr/lib/python2.x/site-packages/_unbound.so*

3732
37333 April 2009: Wouter
3734	- Fixed a bug that caused messages to be stored in the cache too
3735	  long.  Hard to trigger, but NXDOMAINs for nameservers or CNAME
3736	  targets have been more vulnerable to the TTL miscalculation bug.
3737	- documentation test fixed for python addition.
3738
37392 April 2009: Wouter
3740	- pyunbound (libunbound python plugin) compiles using libtool.
3741	- documentation for pythonmod and pyunbound is generated in doc/html.
3742	- iana portlist updated.
3743	- fixed bug in unbound-control flush_zone where it would not flush
3744	  every message in the target domain.  This especially impacted
3745	  NXDOMAIN messages which could remain in the cache regardless.
3746	- python module test package.
3747
37481 April 2009: Wouter
3749	- suppress errors when trying to contact authority servers that gave
3750	  ipv6 AAAA records for their nameservers with ipv4 mapped contents.
3751	  Still tries to do so, could work when deployed in intranet.

3807	- Added tests, unknown algorithms become insecure. fallback works.
3808	- Fix for and test for unknown algorithms in a trust anchor
3809	  definition.  Trust anchors with no supported algos are ignored.
3810	  This means a (higher)DS or DLV entry for them could succeed, and
3811	  otherwise they are treated as insecure.
3812	- domain-insecure: "example.com" statement added. Sets domain

3895	- unbound-checkconf and unbound print warnings when trust anchors
3896	  have unsupported algorithms.
3897	- added contrib/update-itar.sh  This script is similar to
3898	  update-anchor.sh, and updates from the IANA ITAR repository.
3899	  You can provide your own PGP key and trust repo, or can use the
3900	  builtin.  The program uses wget and gpg to work.
3901	- iana portlist updated.
3902	- update-itar.sh: using ftp:// urls because https godaddy certificate
3903	  is not available everywhere and then gives fatal errors.  The

390618 February 2009: Wouter
3907	- more cycle detection. Also for target queries.
3908	- fixup bug where during deletion of the mesh queries the callbacks
3909	  that were reentrant caused assertion failures. Keep the mesh in
3910	  a reentrant safe state.  Affects libunbound, reload of server,
3911	  on quit and flush_requestlist.
3912	- iana portlist updated.
3913
391413 February 2009: Wouter
3915	- forwarder information now per-thread duplicated.
3916	  This keeps it read only for speed, with no locking necessary.

3918	  on the fly.
3919	- document that unbound-host reads no config file by default.
3920	- updated iana portlist.
3921

3940	- iana portlist updated.
3941	- fixup EOL in include directive (reported by Paul Wouters).
3942	  You can no longer specify newlines in the names of included files.
3943	- config parser changed. Gives some syntax errors closer to where they
3944	  occurred. Does not enforce a space after keyword anymore.
3945	  Does not allow literal newlines inside quoted strings anymore.
3946	- verbosity level 5 logs customer IP for new requestlist entries.
3947	- test fix, lexer and cancel test.
3948	- new option log-time-ascii: yes  if you enable it prints timestamps
3949	  in the log file as Feb 06 13:45:26 (like syslog does).
3950	- detect event_base_new in libevent-1.4.1 and later and use it.
3951	- #231 unbound-checkconf -o option prints that value from config file.
3952	  Useful for scripting in management scripts and the like.
3953
39545 February 2009: Wouter
3955	- ldns 1.5.0 rc as tarball included.
3956	- 1.3.0 development continues:
3957	  change in libunbound API: ub_cancel can return an error, that
3958	  the async_id did not exist, or that it was already delivered.
3959	  The result could have been delivered just before the cancel
3960	  routine managed to acquire the lock, so a caller may get the
3961	  result at the same time they call cancel.  For this case,
3962	  ub_cancel tries to return an error code.
3963	  Fixes race condition in ub_cancel() libunbound function.
3964	- MacOSX Leopard cleaner text output from configure.
3965	- initgroups(3) is called to drop secondary group permissions, if
3966	  applicable.
3967	- configure option --with-ldns-builtin forces the use of the
3968	  inluded ldns package with the unbound source.  The -I include
3969	  is put before the others, so it avoids bad include files from
3970	  an older ldns install.
3971	- daemon(3) posix call is used when available.
3972	- testbound test for older fix added.
3973
39744 February 2009: Wouter
3975	- tag for release 1.2.1.
3976	- trunk setup for 1.3.0 development.

3980	- printout more detailed errors on ssl certificate loading failures.
3981	- updated IANA portlist.
3982
398316 January 2009: Wouter
3984	- more quiet about ipv6 network failures, i.e. when ipv6 is not
3985	  available (network unreachable). Debug still printed on high
3986	  verbosity.
3987	- unbound-host -4 and -6 options. Stops annoying ipv6 errors when
3988	  debugging with unbound-host -4 -d ...
3989	- more cycle detection for NS-check, addr-check, root-prime and
3990	  stub-prime queries in the iterator.  Avoids possible deadlock
3991	  when priming fails.
3992
399315 January 2009: Wouter
3994	- bug #229: fixup configure checks for compilation with Solaris
3995	  Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc

3997	- fix bug where unbound could crash using libevent 1.3 and older.
3998	- update testset for recent retry change.
3999
400014 January 2009: Wouter
4001	- 1.2.1 feature: negative caching for failed queries.
4002	  Queries that failed are cached for 5 seconds (NORR_TTL).
4003	  If the failure is local, like out of memory, it is not cached.
4004	- the TTL comparison for the cache used different comparisons,
4005	  causing many cache responses that used the iterator and validator
4006	  state machines unnecessarily.
4007	- retry from 4 to 5 so that EDNS drop retry is part of the first
4008	  query resolve attempt, and cached error does not stop EDNS fallback.
4009	- remove debug prints that protect against bad referrals.
4010	- honor QUIET=no on make commandline (or QUIET=yes ).
4011
401213 January 2009: Wouter
4013	- fixed bug in lameness marking, removed printouts.
4014	- find NS rrset more cleanly for qtype NS.

4018	  are in the negative cache.
4019
402012 January 2009: Wouter
4021	- fixed bug in infrastructure lameness cache, did not lowercase

4035
40367 January 2009: Wouter
4037	- version 1.2.0 in preparation.
4038	- feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
4039	  statements. (Adapted from patch by Paul Wouters).
4040	- typo fix and iana portlist updated.
4041	- porting testsuite; unused var warning, and type fixup.
4042
40436 January 2009: Wouter
4044	- fixup packet-of-death when compiled with --enable-debug.
4045	  A malformed packet could cause an internal assertion failure.
4046	- added test for HINFO canonicalisation behaviour.
4047	- fixup reported problem with transparent local-zone data where
4048	  queries with different type could get nxdomain. Now queries
4049	  with a different name get resolved normally, with different type
4050	  get a correct NOERROR/NODATA answer.
4051	- HINFO no longer downcased for validation, making unbound compatible
4052	  with bind and ldns.
4053	- fix reading included config files when chrooted.
4054	  Give full path names for include files.
4055	  Relative path names work if the start dir equals the working dir.
4056	- fix libunbound message transport when no packet buffer is available.
4057
40585 January 2009: Wouter
4059	- fixup getaddrinfo failure handling for remote control port.

4061	- fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
4062	- comm_timer_set performs base_set operation after event_add.
4063

4065	- fixed bug reported by Duane Wessels: error in DLV lookup, would make
4066	  some zones that had correct DLV keys as insecure.
4067	- follows -rc makedist from ldns changes (no _rc).
4068	- ldns tarball updated with 1.4.1rc for DLV unit test.
4069	- verbose prints about recursion lame detection and server selection.
4070	- fixup BSD port for infra host storage. It hashed wrongly.

4073
407417 December 2008: Wouter
4075	- follows ldns makedist.sh. -rc option. autom4te dir removed.
4076	- unbound-control status command.
4077	- extended statistics has a number of ipv6 queries counter.
4078	  contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
4079
408016 December 2008: Wouter
4081	- follow makedist improvements from ldns, for maintainers prereleases.
4082	- snapshot version uses _ not - to help rpm distinguish the
4083	  version number.
4084

4093
40943 December 2008: Wouter
4095	- Fix problem reported by Jaco Engelbrecht where unbound-control stats
4096	  freezes up unbound if this was compiled without threading, and
4097	  was using multiple processes.
4098	- iana portlist updated.
4099	- test for remote control with interprocess communication.
4100	- created command distribution mechanism so that remote control
4101	  commands other than 'stats' work on all processes in a nonthreaded
4102	  compiled version. dump/load cache work, on the first process.
4103	- fixup remote control local_data addition memory corruption bug.
4104
41051 December 2008: Wouter
4106	- SElinux policy files in contrib/selinux for the unbound daemon,
4107	  by Paul Wouters and Adam Tkac.
4108
410925 November 2008: Wouter
4110	- configure complains when --without-ssl is given (bug #220).
4111	- skip unsupported feature tests on vista/mingw.
4112	- fixup testcode/streamtcp to work on vista/mingw.
4113	- root-hints test checks version of dig required.
4114	- blacklisted servers are polled at a low rate (1%) to see if they
4115	  come back up. But not if there is some other working server.
4116
411724 November 2008: Wouter
4118	- document that the user of the server daemon needs read privileges
4119	  on the keys and certificates generated by unbound-control-setup.
4120	  This is different per system or distribution, usually, running the
4121	  script under the same username as the server uses suffices.
4122	  i.e.  sudo -u unbound unbound-control-setup
4123	- testset port to vista/mingw.
4124	- tcp_sigpipe to freebsd port.
4125
412621 November 2008: Wouter
4127	- fixed tcp accept, errors were printed when they should not.
4128	- unbound-control-setup.sh removes read/write permissions other

4132	- fixup fatal error due to faulty error checking after tcp accept.
4133	- add check in rlimit to avoid integer underflow.
4134	- rlimit check with new formula; better estimate for number interfaces
4135	- nicer comments in rlimit check.

4137	- trunk label is 1.1.2
4138
413919 November 2008: Wouter

4149
415017 November 2008: Wouter
4151	- theoretical fix for problems reported on mailing list.
4152	  If a delegation point has no A but only AAAA and do-ip6 is no,
4153	  resolution would fail. Fixed to ask for the A and AAAA records.
4154	  It has to ask for both always, so that it can fail quietly, from
4155	  TLD perspective, when a zone is only reachable on one transport.
4156	- test for above, only AAAA and doip6 is no. Fix causes A record
4157	  for nameserver to be fetched.
4158	- fixup address duplication on cache fillup for delegation points.
4159	- testset updated for new query answer requirements.
4160

4197	- dname_priv must decompress the name before comparison.
4198	- iana portlist updated.
4199
42005 November 2008: Wouter
4201	- fixed possible memory leak in key_entry_key deletion.
4202	  Would leak a couple bytes when trust anchors were replaced.
4203	- if query and reply qname overlap, the bytes are skipped not copied.
4204	- fixed file descriptor leak when messages were jostled out that
4205	  had outstanding (TCP) replies.
4206	- DNAMEs used from cache have their synthesized CNAMEs initialized
4207	  properly.
4208	- fixed file descriptor leak for localzone type deny (for TCP).
4209	- fixed memleak at exit for nsec3 negative cached zones.
4210	- fixed memleak for the keyword 'nodefault' when reading config.
4211	- made verbosity of 'edns incapable peer' warning higher, so you
4212	  do not get spammed by it.
4213	- caught elusive Bad file descriptor error bug, that would print the
4214	  error while unnecessarily try to listen to a closed fd. Fixed.
4215
42164 November 2008: Wouter
4217	- fixed -Wwrite-strings warnings that result in better code.
4218
42193 November 2008: Wouter
4220	- fixup build process for Mac OSX linker, use ldns b32 compat funcs.
4221	- generated configure with autoconf-2.61.
4222	- iana portlist updated.
4223	- detect if libssl needs libdl.  For static linking with libssl.
4224	- changed to use new algorithm identifiers for sha256/sha512
4225	  from ldns 1.4.0 (need very latest version).
4226	- updated the included ldns tarball.
4227	- proper detection of SHA256 and SHA512 functions (not just sizes).
4228
422923 October 2008: Wouter
4230	- a little more debug info for failure on signer names. prints names.
4231
423222 October 2008: Wouter
4233	- CFLAGS are picked up by configure from the environment.
4234	- iana portlist updated.
4235	- updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
4236	- new stub-prime: yesno option. Default is off, so it does not prime.
4237	  can be turned on to get same behaviour as previous unbound release.
4238	- made automated test that checks if builtin root hints are uptodate.
4239	- finished draft-wijngaards-dnsext-resolver-side-mitigation
4240	  implementation. The unwanted-reply-threshold can be set.
4241	- fixup so fptr_whitelist test in alloc.c works.
4242
424321 October 2008: Wouter
4244	- fix update-anchors.sh, so it does not report different RR order
4245	  as an update.  Sorts the keys in the file.  Updated copyright.
4246	- fixup testbound on windows, the command control pipe doesn't exist.
4247	- skip 08hostlib test on windows, no fork() available.
4248	- made unbound-remote work on windows.
4249
425020 October 2008: Wouter
4251	- quench a log message that is debug only.
4252	- iana portlist updated.
4253	- do not query bogus nameservers.  It is like nameservers that have
4254	  the NS or A or AAAA record bogus are listed as donotquery.
4255	- if server selection is faced with only bad choices, it will
4256	  attempt to get more options to be fetched.
4257	- changed bogus-ttl default value from 900 to 60 seconds.
4258	  In anticipation that operator caused failures are more likely than
4259	  actual attacks at this time.  And thus repeated validation helps
4260	  the operators get the problem fixed sooner.  It makes validation
4261	  failures go away sooner (60 seconds after the zone is fixed).
4262	  Also it is likely to try different nameserver targets every minute,
4263	  so that if a zone is bad on one server but not another, it is
4264	  likely to pick up the 'correct' one after a couple minutes,
4265	  and if the TTL is big enough that solves validation for the zone.
4266	- fixup unbound-control compilation on windows.
4267
426817 October 2008: Wouter
4269	- port Leopard/G5: fixup type conversion size_t/uint32.
4270	  please ranlib, stop file without symbols warning.
4271	- harden referral path now also validates the root after priming.
4272	  It looks up the root NS authoritatively as well as the root servers
4273	  and attemps to validate the entries.
4274
427516 October 2008: Wouter
4276	- Fixup negative TTL values appearing (reported by Attila Nagy).
4277
427815 October 2008: Wouter
4279	- better documentation for 0x20; remove fallback TODO, it is done.
4280	- harden-referral-path feature includes A, AAAA queries for glue,
4281	  as well as very careful NS caching (only when doing NS query).
4282	  A, AAAA use the delegation from the NS-query.
4283
428414 October 2008: Wouter
4285	- fwd_three.tpkg test was flaky.  If the three requests hit the
4286	  wrong threads by chance (or bad OS) then the test would fail.
4287	  Made less flaky by increasing number of retries.
4288	- stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
4289	- ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
4290	  Which includes the ldns_dname_absolute fix.
4291	- fwd_three test remains flaky now that unbound does not stop
4292	  listening when full.  Thus, removed timeout problem.
4293	  It may be serviced by three threads, or maybe by one.
4294	  Mostly only useful for lock-check testing now.
4295
429613 October 2008: Wouter
4297	- fixed recursion servers deployed as authoritative detection, so
4298	  that as a last resort, a +RD query is sent there to get the
4299	  correct answer.
4300	- iana port list update.
4301	- ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
4302
430310 October 2008: Wouter
4304	- fixup tests - the negative cache contained the correct NSEC3s for
4305	  two tests that are supposed to fail to validate.
4306
43079 October 2008: Wouter
4308	- negative cache caps max iterations of NSEC3 done.
4309	- NSEC3 negative cache for qtype DS works.
4310
43118 October 2008: Wouter
4312	- NSEC negative cache for DS.
4313
43146 October 2008: Wouter
4315	- jostle-timeout option, so you can config for slow links.
4316	- 0x20 fallback code.  Tries 3xnumber of nameserver addresses
4317	  queries that must all be the same.  Sent to random nameservers.
4318	- documented choices for DoS, EDNS, 0x20.
4319
43202 October 2008: Wouter
4321	- fixup unlink of pidfile.
4322	- fixup SHA256 algorithm collation code.
4323	- contrib/update-anchor.sh does not overwrite anchors if not needed.
4324	  exits 0 when a restart is needed, other values if not.
4325	  so,  update-anchor.sh -d mydir && /etc/rc.d/unbound restart
4326	  can restart unbound exactly when needed.
4327
432830 September 2008: Wouter
4329	- fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
4330	- tests for sha256 support and downgrade resistance.
4331	- RSASHA256 and RSASHA512 support (using the draft in dnsext),
4332	  using the drafted protocol numbers.
4333	- when using stub on localhost (127.0.0.1@10053) unbound works.
4334	  Like when running NSD to host a local zone, on the same machine.
4335	  The noprime feature. manpages more explanation. Added a test for it.
4336	- shorthand for reverse PTR,  local-data-ptr: "1.2.3.4 www.ex.com"
4337
433829 September 2008: Wouter
4339	- EDNS lameness detection, if EDNS packets are dropped this is
4340	  detected, eventually.
4341	- multiple query timeout rtt backoff does not backoff too much.
4342
434326 September 2008: Wouter

439012 September 2008: Wouter
4391	- removed browser control mentions. Proto speccy.
4392
439311 September 2008: Wouter
4394	- set nonblocking on new TCP streams, because linux does not inherit
4395	  the socket options to the accepted socket.

4421	  is removed too.
4422
44231 September 2008: Wouter
4424	- disallow nonrecursive queries for cache snooping by default.
4425	  You can allow is using access-control: <subnet> allow_snoop.
4426	  The defaults do allow access no authoritative data without RD bit.
4427	- two tests for it and fixups of tests for nonrec refused.
4428
442929 August 2008: Wouter
4430	- version 1.1 number in trunk.
4431	- harden-referral-path option for query for NS records.
4432	  Default turns off expensive, experimental option.
4433
443428 August 2008: Wouter
4435	- fixup logfile handling; it is created with correct permissions
4436	  again. (from bugfix#199).
4437	  Some errors are not written to logfile (pidfile writing, forking),
4438	  and these are only visible by using the -d commandline flag.
4439
444027 August 2008: Wouter
4441	- daemon(3) is causing problems for people. Reverting the patch.
4442	  bug#200, and 199 and 203 contain sideline discussion on it.
4443	- bug#199 fixed: pidfile can be outside chroot. openlog is done before
4444	  chroot and drop permissions.
4445	- config option to set size of aggressive negative cache,
4446	  neg-cache-size.
4447	- bug#203 fixed: dlv has been implemented.

4500	- finished adjusting testset to provide qtype NS answers.
4501
450211 August 2008: Wouter
4503	- Fixup rrset security updates overwriting 2181 trust status.
4504	  This makes validated to be insecure data just as worthless as
4505	  nonvalidated data, and 2181 rules prevent cache overwrites to them.
4506	- Fix assertion fail on bogus key handling.
4507	- dnssec lameness detection works on first query at trust apex.
4508	- NS queries get proper cache and dnssec lameness treatment.

4535	- created tube signaling solution on windows, as a pipe replacement.
4536	  this makes background asynchronous resolution work on windows.
4537	- removed very insecure socketpair compat code. It also did not
4538	  work with event_waiting. Solved by pipe replacement.
4539	- unbound -h prints openssl version number as well.
4540
454122 July 2008: Wouter

4560	  fds than the builtin minievent can handle.
4561
456216 July 2008: Wouter
4563	- made svn tag 1.0.1, trunk now 1.0.2
4564	- sha256 checksums enabled in makedist.sh

4583	- fixup fwd_ancil test typos.
4584	- Fix for newegg lameness : ok for qtype=A, but lame for others.
4585	- fixup unit test for infra cache, test lame merging.
4586	- porting to mingw, bind, listen, getsockopt and setsockopt error
4587	  handling.
4588
458924 June 2008: Wouter
4590	- removed testcode/checklocks from production code compilation path.
4591	- streamtcp can use UDP mode (connected UDP socket), for testing IPv6
4592	  on windows.
4593	- fwd_ancil test fails if platform support is lacking.
4594
459523 June 2008: Wouter
4596	- fixup minitpkg to cleanup on windows with its file locking troubles.
4597	- minitpkg shows skipped tests in report.
4598	- skip ipv6 tests on ipv4 only hosts (requires only ipv6 localhost not
4599	  ipv6 connectivity).
4600	- winsock event handler keeps track of sticky TCP events, that have
4601	  not been fully handled yet. when interest in the event(s) resumes,
4602	  they are sent again. When WOULDBLOCK is returned events are cleared.
4603	- skip tests that need signals when testing on mingw.
4604
460518 June 2008: Wouter
4606	- open testbound replay files in binary mode, because fseek/ftell
4607	  do not work in ascii-mode on windows. The b does nothing on unix.
4608	  unittest and testbound tests work on windows (xp too).
4609	- ioctlsocket prints nicer error message.
4610	- fixed up some TCP porting for winsock.
4611	- lack of IPv6 gives a warning, no fatal error.
4612	- use WSAGetLastError() on windows instead of errno for some errors.
4613
461417 June 2008: Wouter
4615	- outgoing num fds 32 by default on windows ; it supports less
4616	  fds for waiting on than unixes.
4617	- winsock_event minievent handler for windows. (you could also
4618	  attempt to link with libevent/libev ports for windows).
4619	- neater crypto check and gdi32 detection.
4620	- unbound.exe works to resolve and validate www.nlnetlabs.nl on vista.
4621
462216 June 2008: Wouter
4623	- on windows, use windows threads, mutex and thread-local-storage(Tls).
4624	- detect if openssl needs gdi32.
4625	- if no threading, THREADS_DISABLED is defined for use in the code.
4626	- sets USE_WINSOCK if using ws2_32 on windows.
4627	- wsa_strerror() function for more readable errors.
4628	- WSA Startup and Cleanup called in unbound.exe.
4629
463013 June 2008: Wouter

46389 June 2008: Wouter
4639	- in iteration response type code
4640	  * first check for SOA record (negative answer) before NS record
4641	    and lameness.

4678	  - bug 185: --disable-shared not passed along to ldns included with
4679	    unbound. Fixed so that configure parameters are passed to the
4680	    subdir configure script.
4681	    fixed that ./libtool is used always, you can still override
4682	    manually with ./configure libtool=mylibtool or set $libtool in
4683	    the environment.
4684	- update of the ldns tarball to current ldns svn version (fix 181).
4685	- bug 184: -r option for unbound-host, read resolv.conf for

4701	  - gmtime_r is replaced by nonthreadsafe alternative if unavail.
4702	    used in rrsig time validation errors.
4703

4779	- got update for parseunbound.pl statistics script from Kai Storbeck.
4780	- tpkg tests for udp wait list.
4781	- documented 0x20 status.
4782	- fixup chroot and checkconf, it is much smarter now.

478611 April 2008: Wouter
4787	- random port selection out of the configged ports.
4788	- fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
4789	- removed base_port.

4791	- fixup consistency of port_if out array during heavy use.
4792
479310 April 2008: Wouter
4794	- --with-libevent works with latest libevent 1.4.99-trunk.
4795	- added log file statistics perl script to contrib.
4796	- automatic iana ports update from makefile. 60058 available.
4797
47989 April 2008: Wouter
4799	- configure can detect libev(from its build directory) when passed
4800	  --with-libevent=/home/wouter/libev-3.2
4801	  libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
4802	- unused commpoints not listed in epoll list.
4803	- statistics-cumulative option so that the values are not reset.
4804	- config creates array of available ports, 61841 available,
4805	  it excludes <1024 and iana assigned numbers.
4806	  config statements to modify the available port numbers.
4807
48088 April 2008: Wouter
4809	- unbound tries to set the ulimit fds when started as server.
4810	  if that does not work, it will scale back its requirements.
4811
481227 March 2008: Wouter
4813	- documented /dev/random symlink from chrootdir as FAQ entry.
4814
481526 March 2008: Wouter
4816	- implemented AD bit signaling. If a query sets AD bit (but not DO)
4817	  then the AD bit is set in the reply if the answer validated.
4818	  Without including DNSSEC signatures. Useful if you have a trusted
4819	  path from the client to the resolver. Follows dnssec-updates draft.
4820
482125 March 2008: Wouter
4822	- implemented check that for NXDOMAIN and NOERROR answers a query
4823	  section must be present in the reply (by the scrubber). And it must
4824	  be equal to the question sent, at least lowercase folded.
4825	  Previously this feature happened because the cache code refused
4826	  to store such messages. However blocking by the scrubber makes
4827	  sure nothing gets into the RRset cache. Also, this looks like a
4828	  timeout (instead of an allocation failure) and this retries are
4829	  done (which is useful in a spoofing situation).
4830	- RTT banding. Band size 400 msec, this makes band around zero (fast)
4831	  include unknown servers. This makes unbound explore unknown servers.
4832
48337 March 2008: Wouter
4834	- -C config feature for harvest program.
4835	- harvest handles CNAMEs too.
4836
48375 March 2008: Wouter
4838	- patch from Hugo Koji Kobayashi for iterator logs spelling.
4839
48404 March 2008: Wouter
4841	- From report by Jinmei Tatuya, rfc2181 trust value for remainder
4842	  of a cname trust chain is lower; not full answer_AA.
4843	- test for this fix.
4844	- default config file location is /usr/local/etc/unbound.
4845	  Thus prefix is used to determine the location. This is also the
4846	  chroot and pidfile default location.
4847
48483 March 2008: Wouter
4849	- Create 0.10 svn tag.
4850	- 0.11 version in trunk.
4851	- indentation nicer.
4852
485329 February 2008: Wouter
4854	- documentation update.
4855	- fixup port to Solaris of perf test tool.
4856	- updated ldns-tarball with decl-after-statement fixes.
4857
485828 February 2008: Wouter
4859	- fixed memory leaks in libunbound (during cancellation and wait).
4860	- libunbound returns the answer packet in full.
4861	- snprintf compat update.
4862	- harvest performs lookup.
4863	- ldns-tarball update with fix for ldns_dname_label.
4864	- installs to sbin by default.
4865	- install all manual pages (unbound-host and libunbound too).
4866
486727 February 2008: Wouter
4868	- option to use caps for id randomness.
4869	- config file option use-caps-for-id: yes
4870	- harvest debug tool
4871
487226 February 2008: Wouter
4873	- delay utility delays TCP as well. If the server that is forwarded
4874	  to has a TCP error, the delay utility closes the connection.
4875	- delay does REUSE_ADDR, and can handle a server that closes its end.
4876	- answers use casing from query.
4877
487825 February 2008: Wouter
4879	- delay utility works. Gets decent thoughput too (>20000).
4880
488122 February 2008: Wouter
4882	- +2% for recursions, if identical queries (except for destination
4883	  and query ID) in the reply list, avoid re-encoding the answer.
4884	- removed TODO items for optimizations that do not show up in
4885	  profile reports.
4886	- default is now minievent - not libevent. As its faster and
4887	  not needed for regular installs, only for very large port ranges.
4888	- loop check different speedup pkt-dname-reading, 1% faster for
4889	  nocache-recursion check.
4890	- less hashing during msg parse, 4% for recursion.
4891	- small speed fix for dname_count_size_labels, +1 or +2% recursion.
4892	- some speed results noted:
4893	  optimization resulted in +40% for recursion (cache miss) and
4894	  +70 to +80 for cache hits, and +96% for version.bind.
4895	  zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
4896	  www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
4897	  www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
4898	  So, unbound can be about equal qps to NSD in cache hits.
4899	  And about 3.4x faster than BIND in cache performance.
4900	- delay utility for testing.
4901
490221 February 2008: Wouter
4903	- speedup of root-delegation message encoding by 15%.
4904	- minor speedup of compress tree_lookup, maybe 1%.
4905	- speedup of dname_lab_cmp and memlowercmp - the top functions in
4906	  profiler output, maybe a couple percent when it matters.
4907
490820 February 2008: Wouter
4909	- setup speec_cache for need-ldns-testns in dotests.
4910	- check number of queued replies on incoming queries to avoid overload
4911	  on that account.
4912	- fptr whitelist checks are not disabled in optimize mode.
4913	- do-daemonize config file option.
4914	- minievent time share initializes time at start.
4915	- updated testdata for nsec3 new algorithm numbers (6, 7).
4916	- small performance test of packet encoding (root delegation).
4917
491819 February 2008: Wouter
4919	- applied patch to unbound-host man page from Jan-Piet Mens.
4920	- fix donotquery-localhost: yes default (it erroneously was switched
4921	  to default 'no').
4922	- time is only gotten once and the value is shared across unbound.
4923	- unittest cleans up crypto, so that it has no memory leaks.
4924	- mini_event shares the time value with unbound this results in
4925	  +3% speed for cache responses and +9% for recursions.
4926	- ldns tarball update with new NSEC3 sign code numbers.
4927	- perform several reads per UDP operation. This improves performance
4928	  in DoS conditions, and costs very little in normal conditions.
4929	  improves cache response +50%, and recursions +10%.
4930	- modified asynclook test. because the callback from async is not
4931	  in any sort of lock (and thus can use all library functions freely),
4932	  this causes a tiny race condition window when the last lock is
4933	  released for a callback and a new cancel() for that callback.
4934	  The only way to remove this is by putting callbacks into some
4935	  lock window. I'd rather have the small possibility of a callback
4936	  for a cancelled function then no use of library functions in
4937	  callbacks. Could be possible to only outlaw process(), wait(),
4938	  cancel() from callbacks, by adding another lock, but I'd rather not.
4939
494018 February 2008: Wouter
4941	- patch to unbound-host from Jan-Piet Mens.
4942	- unbound host prints errors if fails to configure context.
4943	- fixup perf to resend faster, so that long waiting requests do
4944	  not hold up the queue, they become lost packets or SERVFAILs,
4945	  or can be sent a little while later (i.e. processing time may
4946	  take long, but throughput has to be high).
4947	- fixup iterator operating in no cache conditions (RD flag unset
4948	  after a CNAME).
4949	- streamlined code for RD flag setting.
4950	- profiled code and changed dname compares to be faster.
4951	  The speedup is about +3% to +8% (depending on the test).
4952	- minievent tests for eintr and eagain.
4953
495415 February 2008: Wouter
4955	- added FreeBSD rc.d script to contrib.
4956	- --prefix option for configure also changes directory: pidfile:
4957	  and chroot: defaults in config file.
4958	- added cache speed test, for cache size OK and cache too small.
4959
496014 February 2008: Wouter
4961	- start without a config file (will complain, but start with
4962	  defaults).
4963	- perf test program works.
4964
496513 February 2008: Wouter
4966	- 0.9 released.
4967	- 1.0 development. Printout ldns version on unbound -h.
4968	- start of perf tool.
4969	- bugfix to read empty lines from /etc/hosts.
4970
497112 February 2008: Wouter
4972	- fixup problem with configure calling itself if ldns-src tarball
4973	  is not present.
4974
497511 February 2008: Wouter
4976	- changed library to use ub_ instead of ub_val_ as prefix.
4977	- statistics output text nice.
4978	- etc/hosts handling.
4979	- library function to put logging to a stream.
4980	- set any option interface.
4981
49828 February 2008: Wouter
4983	- test program for multiple queries over a TCP channel.
4984	- tpkg test for stream tcp queries.
4985	- unbound replies to multiple TCP queries on a TCP channel.
4986	- fixup misclassification of root referral with NS in answer
4987	  when validating a nonrec query.
4988	- tag 0.9
4989	- layout of manpages, spelling fix in header, manpages process by
4990	  makedist, list asynclook and tcpstream tests as ldns-testns
4991	  required.
4992
49937 February 2008: Wouter
4994	- moved up all current level 2 to be level 3. And 3 to 4.
4995	  to make room for new debug level 2 for detailed information
4996	  for operators.
4997	- verbosity level 2. Describes recursion and validation.
4998	- cleaner configure script and fixes for libevent solaris.
4999	- signedness for log output memory sizes in high verbosity.
5000
50016 February 2008: Wouter
5002	- clearer explanation of threading configure options.
5003	- fixup asynclook test for nothreading (it creates only one process
5004	  to do the extended test).
5005	- changed name of ub_val_result_free to ub_val_resolve_free.
5006	- removes warning message during library linking, renamed
5007	  libunbound/unbound.c -> libunbound.c and worker to libworker.
5008	- fallback without EDNS if result is NOTIMPL as well as on FORMERR.
5009
50105 February 2008: Wouter
5011	- statistics-interval: seconds option added.
5012	- test for statistics option
5013	- ignore errors making directories, these can occur in parallel builds
5014	- fixup Makefile strip command and libunbound docs typo.
5015
501631 January 2008: Wouter
5017	- bg thread/process reads and writes the pipe nonblocking all the time
5018	  so that even if the pipe is buffered or so, the bg thread does not
5019	  block, and services both pipes and queries.
5020
502130 January 2008: Wouter
5022	- check trailing / on chrootdir in checkconf.
5023	- check if root hints and anchor files are in chrootdir.
5024	- no route to host tcp error is verbosity level 2.
5025	- removed unused send_reply_iov. and its configure check.
5026	- added prints of 'remote address is 1.2.3.4 port 53' to errors
5027	  from netevent; the basic socket errors.
5028
502928 January 2008: Wouter
5030	- fixup uninit use of buffer by libunbound (query id, flags) for
5031	  local_zone answers.
5032	- fixup uninit warning from random.c; also seems to fix sporadic
5033	  sigFPE coming out of openssl.
5034	- made openssl entropy warning more silent for library use. Needs
5035	  verbosity 1 now.
5036	- fixup forgotten locks for rbtree_searches on ctx->query tree.
5037	- random generator cleanup - RND_STATE_SIZE removed, and instead
5038	  a super-rnd can be passed at init to chain init random states.
5039	- test also does lock checks if available.
5040	- protect config access in libworker_setup().
5041	- libevent doesn't like comm_base_exit outside of runloop.
5042	- close fds after removing commpoints only (for epoll, kqueue).
5043
504425 January 2008: Wouter
5045	- added tpkg for asynclook and library use.
5046	- allows localhost to be queried when as a library.
5047	- fixup race condition between cancel and answer (in case of
5048	  really fast answers that beat the cancel).
5049	- please doxygen, put doxygen comment in one place.
5050	- asynclook -b blocking mode and test.
5051	- refactor asynclook, nicer code.
5052	- fixup race problems from opensll in rand init from library, with
5053	  a mutex around the rand init.
5054	- fix pass async_id=NULL to _async resolve().
5055	- rewrote _wait() routine, so that it is threadsafe.
5056	- cancelation is threadsafe.
5057	- asynclook extended test in tpkg.
5058	- fixed two races where forked bg process waits for (somehow shared?)
5059	  locks, so does not service the query pipe on the bg side.
5060	  Now those locks are only held for fg_threads and for bg_as_a_thread.
5061
506224 January 2008: Wouter
5063	- tested the cancel() function.
5064	- asynclook -c (cancel) feature.

5070	- new calls to set forwarding added to header and docs.
5071
507223 January 2008: Wouter
5073	- removed debug prints from if-auto, verb-algo enables some.
5074	- libunbound QUIT setup, remove memory leaks, when using threads
5075	  will share memory for passing results instead of writing it over
5076	  the pipe, only writes ID number over the pipe (towards the handler
5077	  thread that does process() ).
5078
507922 January 2008: Wouter
5080	- library code for async in libunbound/unbound.c.
5081	- fix link testbound.
5082	- fixup exit bug in mini_event.
5083	- background worker query enter and result functions.
5084	- bg query test application asynclook, it looks up multiple
5085	  hostaddresses (A records) at the same time.
5086
508721 January 2008: Wouter
5088	- libworker work, netevent raw commpoints, write_msg, serialize.
5089
509018 January 2008: Wouter
5091	- touch up of manpage for libunbound.
5092	- support for IP_RECVDSTADDR (for *BSD ip4).
5093	- fix for BSD, do not use ip4to6 mapping, make two sockets, once
5094	  ip6 and once ip4, uses socket options.
5095	- goodbye ip4to6 mapping.
5096	- update ldns-testpkts with latest version from ldns-trunk.
5097	- updated makedist for relative ldns pathnames.
5098	- library API with more information inside the result structure.
5099	- work on background resolves.
5100
510117 January 2008: Wouter
5102	- fixup configure in case -lldns is installed.
5103	- fixup a couple of doxygen warnings, about enum variables.
5104	- interface-automatic now copies the interface address from the
5105	  PKT_INFO structure as well.
5106	- manual page with library API, all on one page 'man libunbound'.
5107	- rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
5108
510916 January 2008: Wouter
5110	- incoming queries to the server with TC bit on are replied FORMERR.
5111	- interface-automatic replied the wrong source address on localhost
5112	  queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
5113	  to use ifnum=-1 to mean 'no interface, use kernel route'.
5114
511515 January 2008: Wouter
5116	- interface-automatic feature. experimental. Nice for anycast.
5117	- tpkg test for ip6 ancillary data.
5118	- removed debug prints.
5119	- porting experience, define for Solaris, test refined for BSD
5120	  compatibility. The feature probably will not work on OpenBSD.
5121	- makedist fixup for ldns-src in build-dir.
5122
512314 January 2008: Wouter
5124	- in no debug sets NDEBUG to remove asserts.
5125	- configure --enable-debug is needed for dependency generation
5126	  for assertions and for compiler warnings.
5127	- ldns.tgz updated with ldns-trunk (where buffer.h is updated).
5128	- fix lint, unit test in optimize mode.
5129	- default access control allows ::ffff:127.0.0.1 v6mapped localhost.
5130
513111 January 2008: Wouter
5132	- man page, warning removed.
5133	- added text describing the use of stub zones for private zones.
5134	- checkconf tests for bad hostnames (IP address), and for doubled
5135	  interface lines.
5136	- memory sizes can be given with 'k', 'Kb', or M or G appended.
5137
513810 January 2008: Wouter
5139	- typo in example.conf.
5140	- made using ldns-src that is included the package more portable
5141	  by linking with .lo instead of .o files in the ldns package.
5142	- nicer do-ip6: yes/no documentation.
5143	- nicer linking of libevent .o files.
5144	- man pages render correctly on solaris.
5145
51469 January 2008: Wouter
5147	- fixup openssl RAND problem, when the system is not configured to
5148	  give entropy, and the rng needs to be seeded.
5149
51508 January 2008: Wouter
5151	- print median and quartiles with extensive logging.
5152
51534 January 2008: Wouter
5154	- document misconfiguration in private network.
5155
51562 January 2008: Wouter
5157	- fixup typo in requirements.
5158	- document that 'refused' is a better choice than 'drop' for
5159	  the access control list, as refused will stop retries.
5160
51617 December 2007: Wouter
5162	- unbound-host has a -d option to show what happens. This can help
5163	  with debugging (why do I get this answer).
5164	- fixup CNAME handling, on nodata, sets and display canonname.
5165	- dot removed from CNAME display.
5166	- respect -v for NXDOMAINs.
5167	- updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
5168	- size_t to int for portability of the header file.
5169	- fixup bogus handling.
5170	- dependencies and lint for unbound-host.
5171
51726 December 2007: Wouter
5173	- library resolution works in foreground mode, unbound-host app
5174	  receives data.
5175	- unbound-host prints rdata using ldns.
5176	- unbound-host accepts trust anchors, and prints validation
5177	  information when you give -v.
5178
51795 December 2007: Wouter
5180	- locking in context_new() inside the function.
5181	- setup of libworker.
5182
51834 December 2007: Wouter
5184	- minor Makefile fixup.
5185	- moved module-stack code out of daemon/daemon into services/modstack,
5186	  preparing for code-reuse.
5187	- move context into own header file.
5188	- context query structure.
5189	- removed unused variable pwd from checkconf.
5190	- removed unused assignment from outside netw.
5191	- check timeval length of string.
5192	- fixup error in val_utils getsigner.
5193	- fixup same (*var) error in netblocktostr.
5194	- fixup memleak on parse error in localzone.
5195	- fixup memleak on packet parse error.
5196	- put ; after union in parser.y.
5197	- small hardening in iter_operate against iq==NULL.
5198	- hardening, if error reply with rcode=0 (noerror) send servfail.
5199	- fixup same (*var) error in find_rrset in msgparse, was harmless.
5200	- check return value of evtimer_add().
5201	- fixup lockorder in lruhash_reclaim(), building up a list of locked
5202	  entries one at a time. Instead they are removed and unlocked.
5203	- fptr_wlist for markdelfunc.
5204	- removed is_locked param from lruhash delkeyfunc.
5205	- moved bin_unlock during bin_split purely to please.
5206
52073 December 2007: Wouter
5208	- changed checkconf/ to smallapp/ to make room for more support tools.
5209	  (such as unbound-host).
5210	- install dirs created with -m 755 because they need to be accessible.
5211	- library extensive featurelist added to TODO.
5212	- please doxygen, lint.
5213	- library test application, with basic functionality.
5214	- fix for building in a subdirectory.
5215	- link lib fix for Leopard.
5216
521730 November 2007: Wouter
5218	- makefile that creates libunbound.la, basic file or libunbound.a
5219	  when creating static executables (no libtool).
5220	- more API setup.
5221
522229 November 2007: Wouter
5223	- 0.9 public API start.
5224
522528 November 2007: Wouter
5226	- Changeup plan for 0.8 - no complication needed, a simple solution
5227	  has been chosen for authoritative features.
5228	- you can use single quotes in the config file, so it is possible
5229	  to specify TXT records in local data.
5230	- fixup small memory problem in implicit transparent zone creation.
5231	- test for implicit zone creation and multiple RR RRsets local data.
5232	- local-zone nodefault test.
5233	- show testbound testlist on commit.
5234	- iterator normalizer changes CNAME chains ending in NXDOMAIN where
5235	  the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
5236	  domain exists).
5237	- nicer verbosity: 0 and 1 levels.
5238	- lower nonRDquery chance of eliciting wrongly typed validation
5239	  requiring message from the cache.
5240	- fix for nonRDquery validation typing; nodata is detected when
5241	  SOA record in auth section (all validation-requiring nodata messages
5242	  have a SOA record in authority, so this is OK for the validator),
5243	  and NS record is needed to be a referral.
5244	- duplicate checking when adding NSECs for a CNAME, and test.
5245	- created svn tag 0.8, after completing testbed tests.
5246
524727 November 2007: Wouter
5248	- per suggestion in rfc2308, replaced default max-ttl value with 1 day.
5249	- set size of msgparse lookup table to 32, from 1024, so that its size
5250	  is below the 2048 regional large size threshold, and does not cause
5251	  a call to malloc when a message is parsed.
5252	- update of memstats tool to print number of allocation calls.
5253	  This is what is taking time (not space) and indicates the avg size
5254	  of the allocations as well. region_alloc stat is removed.
5255
525622 November 2007: Wouter
5257	- noted EDNS in-the-middle dropping trouble as a TODO.
5258	  At this point theoretical, no user trouble has been reported.
5259	- added all default AS112 zones.
5260	- answers from local zone content.
5261		* positive answer, the rrset in question
5262		* nodata answer (exist, but not that type).
5263		* nxdomain answer (domain does not exist).
5264		* empty-nonterminal answer.
5265		* But not: wildcard, nsec, referral, rrsig, cname/dname,
5266			or additional section processing, NS put in auth.
5267	- test for correct working of static and transparent and couple
5268	  of important defaults (localhost, as112, reverses).
5269	  Also checks deny and refuse settings.
5270	- fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
5271
527221 November 2007: Wouter
5273	- local zone internal data setup.
5274
527520 November 2007: Wouter
5276	- 0.8 - str2list config support for double string config options.
5277	- local-zone and local-data options, config storage and documentation.
5278
527919 November 2007: Wouter
5280	- do not downcase NSEC and RRSIG for verification. Follows
5281	  draft-ietf-dnsext-dnssec-bis-updates-06.txt.
5282	- fixup leaking unbound daemons at end of tests.
5283	- README file updated.
5284	- nice libevent not found error.
5285	- README talks about gnu make.
5286	- 0.8: unit test for addr_mask and fixups for it.
5287	  and unit test for addr_in_common().
5288	- 0.8: access-control config file element.
5289	  and unit test rpl replay file.
5290	- 0.8: fixup address reporting from netevent.
5291
529216 November 2007: Wouter
5293	- privilege separation is not needed in unbound at this time.
5294	  TODO item marked as such.
5295	- created beta-0.7 branch for support.
5296	- tagged 0.7 for beta release.
5297	- moved trunk to 0.8 for 0.8(auth features) development.
5298	- 0.8: access control list setup.
5299
530015 November 2007: Wouter
5301	- review fixups from Jelte.
5302
530314 November 2007: Wouter
5304	- testbed script does not recreate configure, since its in svn now.
5305	- fixup checkconf test so that it does not test
5306	  /etc/unbound/unbound.conf.
5307	- tag 0.6.
5308
530913 November 2007: Wouter
5310	- remove debug print.
5311	- fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
5312
531312 November 2007: Wouter
5314	- fixup signal handling where SIGTERM could be ignored if a SIGHUP
5315	  arrives later on.
5316	- bugreports to unbound-bugs@nlnetlabs.nl
5317	- fixup testbound so it exits cleanly.
5318	- cleanup the caches on a reload, so that rrsetID numbers won't clash.
5319
53209 November 2007: Wouter
5321	- took ldns snapshot in repo.
5322	- default config file is /etc/unbound/unbound.conf.
5323	  If it doesn't exist, it is installed with the doc/example.conf file.
5324	  The file is not deleted on uninstall.
5325	- default listening is not all, but localhost interfaces.
5326
53278 November 2007: Wouter
5328	- Fixup chroot and drop user privileges.
5329	- new L root ip address in default hints.
5330
53311 November 2007: Wouter
5332	- Fixup of crash on reload, due to anchors in env not NULLed after
5333	  dealloc during deinit.
5334	- Fixup of chroot call. Happens after privileges are dropped, so
5335	  that checking the passwd entry still works.
5336	- minor touch up of clear() hashtable function.
5337	- VERB_DETAIL prints out what chdir, username, chroot is being done.
5338	- when id numbers run out, caches are cleared, as in design notes.
5339	  Tested with a mock setup with very few bits in id, it worked.
5340	- harden-dnssec-stripped: yes is now default. It insists on dnssec
5341	  data for trust anchors. Included tests for the feature.
5342
534331 October 2007: Wouter
5344	- cache-max-ttl config option.
5345	- building outside sourcedir works again.
5346	- defaults more secure:
5347		username: "unbound"
5348		chroot: "/etc/unbound"
5349	  The operator can override them to be less secure ("") if necessary.
5350	- fix horrible oversight in sorting rrset references in a message,
5351	  sort per reference key pointer, not on referencepointer itself.
5352	- pidfile: "/etc/unbound/unbound.pid" is now the default.
5353	- tests changed to reflect the updated default.
5354	- created hashtable clear() function that respects locks.
5355
535630 October 2007: Wouter
5357	- fixup assertion failure that relied on compressed names to be
5358	  smaller than uncompressed names. A packet from comrite.com was seen
5359	  to be compressed to a larger size. Added it as unit test.
5360	- quieter logging at low verbosity level for common tcp messages.
5361	- no greedy TTL update.
5362
536323 October 2007: Wouter
5364	- fixup (grand-)parent problem for dnssec-lameness detection.
5365	- fixup tests to do additional section processing for lame replies,
5366	  since the detection needs that.
5367	- no longer trust in query section in reply during dnssec lame detect.
5368	- dnssec lameness does not make the server never ever queried, but
5369	  non-preferred. If no other servers exist or answer, the dnssec lame
5370	  server is used; the fastest dnssec lame server is chosen.
5371	- added test then when trust anchor cannot be primed (nodata), the
5372	  insecure mode from unbound works.
5373	- Fixup max queries per thread, any more are dropped.
5374
537522 October 2007: Wouter
5376	- added donotquerylocalhost config option. Can be turned off for
5377	  out test cases.
5378	- ISO C compat changes.
5379	- detect RA-no-AA lameness, as LAME.
5380	- DNSSEC-lameness detection, as LAME.
5381	  See notes in requirements.txt for choices made.
5382	- tests for lameness detection.
5383	- added all to make test target; need unbound for fwd tests.
5384	- testbound does not pollute /etc/unbound.
5385
538619 October 2007: Wouter
5387	- added configure (and its files) to svn, so that the trunk is easier
5388	  to use. ./configure, config.guess, config.sub, ltmain.sh,
5389	  and config.h.in.
5390	- added yacc/lex generated files, util/configlexer.c,
5391	  util/configparser.c util/configparser.h, to svn.
5392	- without lex no attempt to use it.
5393	- unsecure response validation collated into one block.
5394	- remove warning about const cast of cfgfile name.
5395	- outgoing-interfaces can be different from service interfaces.
5396	- ldns-src configure is done during unbound configure and
5397	  ldns-src make is done during unbound make, and so inherits the
5398	  make arguments from the unbound make invocation.
5399	- nicer error when libevent problem causes instant exit on signal.
5400	- read root hints from a root hint file (like BIND does).
5401
540218 October 2007: Wouter
5403	- addresses are logged with errors.
5404	- fixup testcode fake event to remove pending before callback
5405	  since the callback may create new pending items.
5406	- tests updated because retries are now in iterator module.
5407	- ldns-testpkts code is checked for differences between unbound
5408	  and ldns by makedist.sh.
5409	- ldns trunk from today added in svn repo for fallback in case
5410	  no ldns is installed on the system.
5411	  make download_ldns refreshes the tarball with ldns svn trunk.
5412	- ldns-src.tar.gz is used if no ldns is found on the system, and
5413	  statically linked into unbound.
5414	- start of regional allocator code.
5415	- regional uses less memory and variables, simplified code.
5416	- remove of region-allocator.
5417	- alloc cache keeps a cache of recently released regional blocks,
5418	  up to a maximum.
5419	- make unit test cleanly free memory.
5420
542117 October 2007: Wouter
5422	- fixup another cycle detect and ns-addr timeout resolution bug.
5423	  This time by refusing delegations from the cache without addresses
5424	  when resolving a mandatory-glue nameserver-address for that zone.
5425	  We're going to have to ask a TLD server anyway; might as well be
5426	  the TLD server for this name. And this resolves a lot of cases where
5427	  the other nameserver names lead to cycles or are not available.
5428	- changed random generator from random(3) clone to arc4random wrapped
5429	  for thread safety. The random generator is initialised with
5430	  entropy from the system.
5431	- fix crash where failure to prime DNSKEY tried to print null pointer
5432	  in the log message.
5433	- removed some debug prints, only verb_algo (4) enables them.
5434	- fixup test; new random generator took new paths; such as one
5435	  where no scripted answer was available.
5436	- mark insecure RRs as insecure.
5437	- fixup removal of nonsecure items from the additional.
5438	- reduced timeout values to more realistic, 376 msec (262 msec has
5439	  90% of roundtrip times, 512 msec has 99% of roundtrip times.)
5440	- server selection failover to next server after timeout (376 msec).
5441
544216 October 2007: Wouter
5443	- no malloc in log_hex.
5444	- assertions around system calls.
5445	- protect against gethostname without ending zero.
5446	- ntop output is null terminated by unbound.
5447	- pidfile content null termination
5448	- various snprintf use sizeof(stringbuf) instead of fixed constant.
5449	- changed loopdetect % 8 with & 0x7 since % can become negative for
5450	  weird negative input and particular interpretation of integer math.
5451	- dname_pkt_copy checks length of result, to protect result buffers.
5452	  prints an error, this should not happen. Bad strings should have
5453	  been rejected earlier in the program.
5454	- remove a size_t underflow from msgreply size func.
5455
545615 October 2007: Wouter
5457	- nicer warning.
5458	- fix IP6 TCP, wrong definition check. With test package.
5459	- fixup the fact that the query section was not compressed to,
5460	  the code was there but was called by value instead of by reference.
5461	  And test for the case, uses xxd and nc.
5462	- more portable ip6 check for sockaddr types.
5463
54648 October 2007: Wouter
5465	- --disable-rpath option in configure for 64bit systems with
5466	  several dynamic lib dirs.
5467
54687 October 2007: Wouter
5469	- fixup tests for no AD bit in non-DO queries.
5470	- test that makes sure AD bit is not set on non-DO query.
5471
54726 October 2007: Wouter
5473	- removed logfile open early. It did not have the proper permissions;
5474	  it was opened as root instead of the user. And we cannot change user
5475	  id yet, since chroot and bind ports need to be done.
5476	- callback checks for event callbacks done from mini_event. Because
5477	  of deletions cannot do this from netevent. This means when using
5478	  libevent the protection does not work on event-callbacks.
5479	- fixup too small reply (did not zero counts).
5480	- fixup reply no longer AD bit when query without DO bit.
5481
54825 October 2007: Wouter
5483	- function pointer whitelist.
5484
54854 October 2007: Wouter
5486	- overwrite sensitive random seed value after use.
5487	- switch to logfile very soon if not -d (console attached).
5488	- error messages do not reveal the trustanchor contents.
5489	- start work on function pointer whitelists.
5490
54913 October 2007: Wouter
5492	- fix for multiple empty nonterminals, after multiple DSes in the
5493	  chain of trust.
5494	- mesh checks if modules are looping, and stops them.
5495	- refetch with CNAMEd nameserver address regression test added.
5496	- fixup line count bug in testcode, so testbound prints correct line
5497	  number with parse errors.
5498	- unit test for multiple ENT case.
5499	- fix for cname out of validated unsec zone.
5500	- fixup nasty id=0 reuse. Also added assertions to detect its
5501	  return (the assertion catches in the existing test cases).
5502
55031 October 2007: Wouter
5504	- skip F77, CXX, objC tests in configure step.
5505	- fixup crash in refetch glue after a CNAME.
5506	  and protection against similar failures (with error print).
5507
550828 September 2007: Wouter
5509	- test case for unbound-checkconf, fixed so it also checks the
5510	  interface: statements.
5511
551226 September 2007: Wouter
5513	- SIGHUP will reopen the log file.
5514	- Option to log to syslog.
5515	- please lint, fixup tests (that went to syslog on open, oops).
5516	- config check program.
5517
551825 September 2007: Wouter
5519	- tests for NSEC3. Fixup bitmap checks for NSEC3.
5520	- positive ANY response needs to check if wildcard expansion, and
5521	  check that original data did not exist.
5522	- tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
5523	  delegation, for abuse of child zone apex nsec3.
5524	- create 0.5 release tag.
5525
552624 September 2007: Wouter
5527	- do not make test programs by default.
5528	- But 'make test' will perform all of the tests.
5529	- Advertise builtin select libevent alternative when no libevent
5530	  is found.
5531	- signit can generate NSEC3 hashes, for generating tests.
5532	- multiple nsec3 parameters in message test.
5533	- too high nsec3 iterations becomes insecure test.
5534
553521 September 2007: Wouter
5536	- fixup empty_DS_name allocated in wrong region (port DEC Alpha).
5537	- fixup testcode lock safety (port FreeBSD).
5538	- removes subscript has type char warnings (port Solaris 9).
5539	- fixup of field with format type to int (port MacOS/X intel).
5540	- added test for infinite loop case in nonRD answer validation.
5541	  It was a more general problem, but hard to reproduce. When an
5542	  unsigned rrset is being validated and the key fetched, the DS
5543	  sequence is followed, but if the final name has no DS, then no
5544	  proof is possible - the signature has been stripped off.
5545
554620 September 2007: Wouter
5547	- fixup and test for NSEC wildcard with empty nonterminals.
5548	- makedist.sh fixup for svn info.
5549	- acl features request in plan.
5550	- improved DS empty nonterminal handling.
5551	- compat with ANS nxdomain for empty nonterminals. Attempts the nodata
5552	  proof anyway, which succeeds in ANS failure case.
5553	- striplab protection in case it becomes -1.
5554	- plans for static and blacklist config.
5555
555619 September 2007: Wouter
5557	- comments about non-packed usage.
5558	- plan for overload support in 0.6.
5559	- added testbound tests for a failed resolution from the logs
5560	  and for failed prime when missing glue.
5561	- fixup so useless delegation points are not returned from the
5562	  cache. Also the safety belt is used if priming fails to complete.
5563	- fixup NSEC rdata not to be lowercased, bind compat.
5564
556518 September 2007: Wouter
5566	- wildcard nsec3 testcases, and fixup to get correct wildcard name.
5567	- validator prints subtype classification for debug.
5568
556917 September 2007: Wouter
5570	- NSEC3 hash cache unit test.
5571	- validator nsec3 nameerror test.
5572
557314 September 2007: Wouter
5574	- nsec3 nodata proof, nods proof, wildcard proof.
5575	- nsec3 support for cname chain ending in noerror or nodata.
5576	- validator calls nsec3 proof routines if no NSECs prove anything.
5577	- fixup iterator bug where it stored the answer to a cname under
5578	  the wrong qname into the cache. When prepending the cnames, the
5579	  qname has to be reset to the original qname.
5580
558113 September 2007: Wouter
5582	- nsec3 find matching and covering, ce proof, prove namerror msg.
5583
558412 September 2007: Wouter
5585	- fixup of manual page warnings, like for NSD bugreport.
5586	- nsec3 work, config, max iterations, filter, and hash cache.
5587
55886 September 2007: Wouter
5589	- fixup to find libevent on mac port install.
5590	- fixup size_t vs unsigned portability in validator/sigcrypt.
5591	- please compiler on different platforms, for unreachable code.
5592	- val_nsec3 file.
5593	- pthread_rwlock type is optional, in case of old pthread libs.
5594
55955 September 2007: Wouter
5596	- cname, name error validator tests.
5597	- logging of qtype ANY works.
5598	- ANY type answers get RRSIG in answer section of replies (but not
5599	  in other sections, unless DO bit is on).
5600	- testbound can replay a TCP query (set MATCH TCP in the QUERY).
5601	- DS and noDS referral validation test.
5602	- if you configure many trust anchors, parent trust anchors can
5603	  securely deny existence of child trust anchors, if validated.
5604	- not all *.name NSECs are present because a wildcard was matched,
5605	  and *.name NSECs can prove nodata for empty nonterminals.
5606	  Also, for wildcard name NSECs, check they are not from the parent
5607	  zone (for wildcarded zone cuts), and check absence of CNAME bit,
5608	  for a nodata proof.
5609	- configure option for memory allocation debugging.
5610	- port configure option for memory allocation to solaris10.
5611
56124 September 2007: Wouter
5613	- fixup of Leakage warning when serviced queries processed multiple
5614	  callbacks for the same query from the same server.
5615	- testbound removes config file from /tmp on failed exit.
5616	- fixup for referral cleanup of the additional section.
5617	- tests for cname, referral validation.
5618	- neater testbound tpkg output.
5619	- DNAMEs no longer match their apex when synthesized from the cache.
5620	- find correct signer name for DNAME responses.
5621	- wildcarded DNAME test and fixup code to detect.
5622	- prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
5623	  So that wildcarded CNAMEs get their NSEC with them to the answer.
5624	- test for a CNAME to a DNAME to a CNAME to an answer, all from
5625	  different domains, for key fetching and signature checking of
5626	  CNAME'd messages.
5627
56283 September 2007: Wouter
5629	- Fixed error in iterator that would cause assertion failure in
5630	  validator. CNAME to a NXDOMAIN response was collated into a response
5631	  with both a CNAME and the NXDOMAIN rcode. Added a test that the
5632	  rcode is changed to NOERROR (because of the CNAME).
5633	- timeout on tcp does not lead to spurious leakage detect.
5634	- account memory for name of lame zones, so that memory leakages does
5635	  not show lame cache growth as a leakage growth.
5636	- config setting for lameness cache expressed in bytes, instead of
5637	  number of entries.
5638	- tool too summarize allocations per code line.
5639
564031 August 2007: Wouter
5641	- can read bind trusted-keys { ... }; files, in a compatibility mode.
5642	- iterator should not detach target queries that it still could need.
5643	  the protection against multiple outstanding queries is moved to a
5644	  current_query num check.
5645	- validator nodata, positive, referral tests.
5646	- dname print can print '*' wildcard.
5647
564830 August 2007: Wouter
5649	- fixup override date config option.
5650	- config options to control memory usage.
5651	- caught bad free of un-alloced data in worker_send error case.
5652	- memory accounting for key cache (trust anchors and temporary cache).
5653	- memory accounting fixup for outside network tcp pending waits.
5654	- memory accounting fixup for outside network tcp callbacks.
5655	- memory accounting for iterator fixed storage.
5656	- key cache size and slabs config options.
5657	- lib crypto cleanups at exit.
5658
565929 August 2007: Wouter
5660	- test tool to sign rrsets for testing validator with.
5661	- added RSA and DSA test keys, public and private pairs, 512 bits.
5662	- default configuration is with validation enabled.
5663	  Only a trust-anchor needs to be configured for DNSSEC to work.
5664	- do not convert to DER for DSA signature verification.
5665	- validator replay test file, for a DS to DNSKEY DSA key prime and
5666	  positive response.
5667
566828 August 2007: Wouter
5669	- removed double use for udp buffers, that could fail,
5670	  instead performs a malloc to do the backup.
5671	- validator validates referral messages, by validating all the rrsets
5672	  and stores the rrsets in the cache. Further referral (nonRD queries)
5673	  replies are made from the rrset cache directly. Unless unchecked
5674	  rrsets are encountered, there are then validated.
5675	- enforce that signing is done by a parent domain (or same domain).
5676	- adjust TTL downwards if rrset TTL bigger than signature allows.
5677	- permissive mode feature, sets AD bit for secure, but bogus does
5678	  not give servfail (bogus is changed into indeterminate).
5679	- optimization of rrset verification. rr canonical sorting is reused,
5680	  for the same rrset. canonical rrset image in buffer is reused for
5681	  the same signature.
5682	- if the rrset is too big (64k exactly + large owner name) the
5683	  canonicalization routine will fail if it does not fit in buffer.
5684	- faster verification for large sigsets.
5685	- verb_detail mode reports validation failures, but not the entire
5686	  algorithm for validation. Key prime failures are reported as
5687	  verb_ops level.
5688
568927 August 2007: Wouter
5690	- do not garble the edns if a cache answer fails.
5691	- answer norecursive from cache if possible.
5692	- honor clean_additional setting when returning secure non-recursive
5693	  referrals.
5694	- do not store referral in msg cache for nonRD queries.
5695	- store verification status in the rrset cache to speed up future
5696	  verification.
5697	- mark rrsets indeterminate and insecure if they are found to be so.
5698	  and store this in the cache.
5699
570024 August 2007: Wouter
5701	- message is bogus if unsecure authority rrsets are present.
5702	- val-clean-additional option, so you can turn it off.
5703	- move rrset verification out of the specific proof types into one
5704	  routine. This makes the proof routines prettier.
5705	- fixup cname handling in validator, cname-to-positive and cname-to-
5706	  nodata work.
5707	- Do not synthesize DNSKEY and DS responses from the rrset cache if
5708	  the rrset is from the additional section. Signatures may have
5709	  fallen off the packet, and cause validation failure.
5710	- more verbose signature date errors (with the date attached).
5711	- increased default infrastructure cache size. It is important for
5712	  performance, and 1000 entries are only 212k (or a 400 k total cache
5713	  size). To 10000 entries (for 2M entries, 4M cache size).
5714
571523 August 2007: Wouter
5716	- CNAME handling - move needs_validation to before val_new().
5717	  val_new() setups the chase-reply to be an edited copy of the msg.
5718	  new classification, and find signer can find for it.
5719	  removal of unsigned crap from additional, and query restart for
5720	  cname.
5721	- refuse to follow wildcarded DNAMEs when validating.
5722	  But you can query for qtype ANY, or qtype DNAME and validate that.
5723
572422 August 2007: Wouter
5725	- bogus TTL.
5726	- review - use val_error().
5727
572821 August 2007: Wouter
5729	- ANY response validation.
5730	- store security status in cache.
5731	- check cache security status and either send the query to be
5732	  validated, return the query to client, or send servfail to client.
5733	  Sets AD bit on validated replies.
5734	- do not examine security status on an error reply in mesh_done.
5735	- construct DS, DNSKEY messages from rrset cache.
5736	- manual page entry for override-date.
5737
573820 August 2007: Wouter
5739	- validate and positive validation, positive wildcard NSEC validation.
5740	- nodata validation, nxdomain validation.
5741
574218 August 2007: Wouter
5743	- process DNSKEY response in FINDKEY state.
5744
574517 August 2007: Wouter
5746	- work on DS2KE routine.
5747	- val_nsec.c for validator NSEC proofs.
5748	- unit test for NSEC bitmap reading.
5749	- dname iswild and canonical_compare with unit tests.
5750
575116 August 2007: Wouter
5752	- DS sig unit test.
5753	- latest release libevent 1.3c and 1.3d have threading fixed.
5754	- key entry fixup data pointer and ttl absolute.
5755	- This makes a key-prime succeed in validator, with DS or DNSKEY as
5756	  trust-anchor.
5757	- fixup canonical compare byfield routine, fix bug and also neater.
5758	- fixed iterator response type classification for queries of type
5759	  ANY and NS.
5760	  dig ANY gives sometimes NS rrset in AN and NS section, and parser
5761	  removes the NS section duplicate. dig NS gives sometimes the NS
5762	  in the answer section, as referral.
5763	- validator FINDKEY state.
5764
576515 August 2007: Wouter
5766	- crypto calls to verify signatures.
5767	- unit test for rrsig verification.
5768
576914 August 2007: Wouter
5770	- default outgoing ports changed to avoid port 2049 by default.
5771	  This port is widely blocked by firewalls.
5772	- count infra lameness cache in memory size.
5773	- accounting of memory improved
5774	- outbound entries are allocated in the query region they are for.
5775	- extensive debugging for memory allocations.
5776	- --enable-lock-checks can be used to enable lock checking.
5777	- protect undefs in config.h from autoheaders ministrations.
5778	- print all received udp packets. log hex will print on multiple
5779	  lines if needed.
5780	- fixed error in parser with backwards rrsig references.
5781	- mark cycle targets for iterator did not have CD flag so failed
5782	  its task.
5783
578413 August 2007: Wouter
5785	- fixup makefile, if lexer is missing give nice error and do not
5786	  mess up the dependencies.
5787	- canonical compare routine updated.
5788	- canonical hinfo compare.
5789	- printout list of the queries that the mesh is working on.
5790
579110 August 2007: Wouter
5792	- malloc and free overrides that track total allocation and frees.
5793	  for memory debugging.
5794	- work on canonical sort.
5795
57969 August 2007: Wouter
5797	- canonicalization, signature checks
5798	- dname signature label count and unit test.
5799	- added debug heap size print to memory printout.
5800	- typo fixup in worker.c
5801	- -R needed on solaris.
5802	- validator override option for date check testing.
5803
58048 August 2007: Wouter
5805	- ldns _raw routines created (in ldns trunk).
5806	- sigcrypt DS digest routines
5807	- val_utils uses sigcrypt to perform signature cryptography.
5808	- sigcrypt keyset processing
5809
58107 August 2007: Wouter
5811	- security status type.
5812	- security status is copied when rdata is equal for rrsets.
5813	- rrset id is updated to invalidate all the message cache entries
5814	  that refer to NSEC, NSEC3, DNAME rrsets that have changed.
5815	- val_util work
5816	- val_sigcrypt file for validator signature checks.
5817
58186 August 2007: Wouter
5819	- key cache for validator.
5820	- moved isroot and dellabel to own dname routines, with unit test.
5821
58223 August 2007: Wouter
5823	- replanning.
5824	- scrubber check section of lame NS set.
5825	- trust anchors can be in config file or read from zone file,
5826	  DS and DNSKEY entries.
5827	- unit test trust anchor storage.
5828	- trust anchors converted to packed rrsets.
5829	- key entry definition.
5830
58312 August 2007: Wouter
5832	- configure change for latest libevent trunk version (needs -lrt).
5833	- query_done and walk_supers are moved out of module interface.
5834	- fixup delegation point duplicates.
5835	- fixup iterator scrubber; lame NS set is let through the scrubber
5836	  so that the classification is lame.
5837	- validator module exists, and does nothing but pass through,
5838	  with calling of next module and return.
5839	- validator work.
5840
58411 August 2007: Wouter
5842	- set version to 0.5
5843	- module work for module to module interconnections.
5844	- config of modules.
5845	- detect cycle takes flags.
5846
584731 July 2007: Wouter
5848	- updated plan
5849	- release 0.4 tag.
5850
585130 July 2007: Wouter
5852	- changed random state init, so that sequential process IDs are not
5853	  cancelled out by sequential thread-ids in the random number seed.
5854	- the fwd_three test, which sends three queries to unbound, and
5855	  unbound is kept waiting by ldns-testns for 3 seconds, failed
5856	  because the retry timeout for default by unbound is 3 seconds too,
5857	  it would hit that timeout and fail the test. Changed so that unbound
5858	  is kept waiting for 2 seconds instead.
5859
586027 July 2007: Wouter
5861	- removed useless -C debug option. It did not work.
5862	- text edit of documentation.
5863	- added doc/CREDITS file, referred to by the manpages.
5864	- updated planning.
5865
586626 July 2007: Wouter
5867	- cycle detection, for query state dependencies. Will attempt to
5868	  circumvent the cycle, but if no other targets available fails.
5869	- unit test for AXFR, IXFR response.
5870	- test for cycle detection.
5871
587225 July 2007: Wouter
5873	- testbound read ADDRESS and check it.
5874	- test for version.bind and friends.
5875	- test for iterator chaining through several referrals.
5876	- test and fixup for refetch for glue. Refetch fails if glue
5877	  is still not provided.
5878
587924 July 2007: Wouter
5880	- Example section in config manual.
5881	- Addr stored for range and moment in replay.
5882
588320 July 2007: Wouter
5884	- Check CNAME chain before returning cache entry with CNAMEs.
5885	- Option harden-glue, default is on. It will discard out of zone
5886	  data. If disabled, performance is faster, but spoofing attempts
5887	  become a possibility. Note that still normalize scrubbing is done,
5888	  and that the potentially spoofed data is used for infrastructure
5889	  and not returned to the client.
5890	- if glue times out, refetch by asking parent of delegation again.
5891	  Much like asking for DS at the parent side.
5892	- TODO items from forgery-resilience draft.
5893	  and on memory handling improvements.
5894	- renamed module_event_timeout to module_event_noreply.
5895	- memory reporting code; reports on memory usage after handling
5896	  a network packet (not on cache replies).
5897
589819 July 2007: Wouter
5899	- shuffle NS selection when getting nameserver target addresses.
5900	- fixup of deadlock warnings, yield cpu in checklock code so that
5901	  freebsd scheduler selects correct process to run.
5902	- added identity and version config options and replies.
5903	- store cname messages complete answers.
5904
590518 July 2007: Wouter
5906	- do not query addresses, 127.0.0.1, and ::1 by default.
5907
590817 July 2007: Wouter
5909	- forward zone options in config file.
5910	- forward per zone in iterator. takes precedence over stubs.
5911	- fixup commithooks.
5912	- removed forward-to and forward-to-port features, subsumed by
5913	  new forward zones.
5914	- fix parser to handle absent server: clause.
5915	- change untrusted rrset test to account for scrubber that is now
5916	  applied during the test (which removes the poison, by the way).
5917	- feature, addresses can be specified with @portnumber, like nsd.conf.
5918	- test config files changed over to new forwarder syntax.
5919
592027 June 2007: Wouter
5921	- delete of mesh does a postorder traverse of the tree.
5922	- found and fixed a memory leak. For TTL=0 messages, that would
5923	  not be cached, instead the msg-replyinfo structure was leaked.
5924	- changed server selection so it will filter out hosts that are
5925	  unresponsive. This is defined as a host with the maximum rto value.
5926	  This means that unbound tried the host for retries up to 120 secs.
5927	  The rto value will time out after host-ttl seconds from the cache.
5928	  This keeps such unresolvable queries from taking up resources.
5929	- utility for keeping histogram.
5930
593126 June 2007: Wouter
5932	- mesh is called by worker, and iterator uses it.
5933	  This removes the hierarchical code.
5934	  QueryTargets state and Finished state are merged for iterator.
5935	- forwarder mode no longer sets AA bit on first reply.
5936	- rcode in walk_supers is not needed.
5937
593825 June 2007: Wouter
5939	- more mesh work.
5940	- error encode routine for ease.
5941
594222 June 2007: Wouter
5943	- removed unused _node iterator value from rbtree_t. Takes up space.
5944	- iterator can handle querytargets state without a delegation point
5945	  set, so that a priming(stub) subquery error can be handled.
5946	- iterator stores if it is priming or not.
5947	- log_query_info() neater logging.
5948	- changed iterator so that it does not alter module_qstate.qinfo
5949	  but keeps a chase query info. Also query_flags are not altered,
5950	  the iterator uses chase_flags.
5951	- fixup crash in case no ports for the family exist.
5952
595321 June 2007: Wouter
5954	- Fixup secondary buffer in case of error callback.
5955	- cleanup slumber list of runnable states.
5956	- module_subreq_depth fails to work in slumber list.
5957	- fixup query release for cached results to sub targets.
5958	- neater error for tcp connection failure, shows addr in verbose.
5959	- rbtree_init so that it can be used with preallocated memory.
5960
596120 June 2007: Wouter
5962	- new -C option to enable coredumps after forking away.
5963	- doc update.
5964	- fixup CNAME generation by scrubber, and memory allocation of it.
5965	- fixup deletion of serviced queries when all callbacks delete too.
5966	- set num target queries to 0 when you move them to slumber list.
5967	- typo in check caused subquery errors to be ignored, fixed.
5968	- make lint happy about rlim_t.
5969	- freeup of modules after freeup of module-states.
5970	- duplicate replies work, this uses secondary udp buffer in outnet.
5971
597219 June 2007: Wouter
5973	- nicer layout in stats.c, review 0.3 change.
5974	- spelling improvement, review 0.3 change.
5975	- uncapped timeout for server selection, so that very fast or slow
5976	  servers will stand out from the rest.
5977	- target-fetch-policy: "3 2 1 0 0" config setting.
5978	- fixup queries answered without RD bit (for root prime results).
5979	- refuse AXFR and IXFR requests.
5980	- fixup RD flag in error reply from iterator. fixup RA flag from
5981	  worker error reply.
5982	- fixup encoding of very short edns buffer sizes, now sets TC bit.
5983	- config options harden-short-bufsize and harden-large-queries.
5984
598518 June 2007: Wouter
5986	- same, move subqueries to slumber list when first has resolved.
5987	- fixup last fix for duplicate callbacks.
5988	- another offbyone in targetcounter. Also in Java prototype by the way.
5989
599015 June 2007: Wouter
5991	- if a query asks to be notified of the same serviced query result
5992	  multiple times, this will succeed. Only one callback will happen;
5993	  multiple outbound-list entries result (but the double cleanup of it
5994	  will not matter).
5995	- when iterator moves on due to CNAME or referral, it will remove
5996	  the subqueries (for other targets). These are put on the slumber
5997	  list.
5998	- state module wait subq is OK with no new subqs, an old one may have
5999	  stopped, with an error, and it is still waiting for other ones.
6000	- if a query loops, halt entire query (easy way to clean up properly).
6001
600214 June 2007: Wouter
6003	- num query targets was > 0 , not >= 0 compared, so that fetch
6004	  policy of 0 did nothing.
6005
600613 June 2007: Wouter
6007	- debug option: configure --enable-static-exe for compile where
6008	  ldns and libevent are linked statically. Default is off.
6009	- make install and make uninstall. Works with static-exe and without.
6010	  installation of unbound binary and manual pages.
6011	- alignment problem fix on solaris 64.
6012	- fixup address in case of TCP error.
6013
601412 June 2007: Wouter
6015	- num target queries was set to 0 at a bad time. Default it to 0 and
6016	  increase as target queries are done.
6017	- synthesize CNAME and DNAME responses from the cache.
6018	- Updated doxygen config for doxygen 1.5.
6019	- aclocal newer version.
6020	- doxygen 1.5 fixes for comments (for the strict check on docs).
6021
602211 June 2007: Wouter
6023	- replies on TCP queries have the address field set in replyinfo,
6024	  for serviced queries, because the initiator does not know that
6025	  a TCP fallback has occured.
6026	- omit DNSSEC types from nonDO replies, except if qtype is ANY or
6027	  if qtype directly queries for the type (and then only show that
6028	  'unknown type' in the answer section).
6029	- fixed message parsing where rrsigs on their own would be put
6030	  in the signature list over the rrsig type.
6031
60327 June 2007: Wouter
6033	- fixup error in double linked list insertion for subqueries and
6034	  for outbound list of serviced queries for iterator module.
6035	- nicer printout of outgoing port selection.
6036	- fixup cname target readout.
6037	- nicer debug output.
6038	- fixup rrset counts when prepending CNAMEs to the answer.
6039	- fixup rrset TTL for prepended CNAMEs.
6040	- process better check for looping modules, and which submodule to
6041	  run next.
6042	- subreq insertion code fixup for slumber list.
6043	- VERB_DETAIL, verbosity: 2 level gives short but readable output.
6044	  VERB_ALGO, verbosity: 3 gives extensive output.
6045	- fixup RA bit in cached replies.
6046	- fixup CNAME responses from the cache no longer partial response.
6047	- error in network send handled without leakage.
6048	- enable ip6 from config, and try ip6 addresses if available,
6049	  if ip6 is not connected, skips to next server.
6050
60515 June 2007: Wouter
6052	- iterator state finished.
6053	- subrequests without parent store in cache and stop.
6054	- worker slumber list for ongoing promiscuous queries.
6055	- subrequest error handling.
6056	- priming failure returns SERVFAIL.
6057	- priming gives LAME result, returns SERVFAIL.
6058	- debug routine to print dns_msg as handled by iterator.
6059	- memleak in config file stubs fixup.
6060	- more small bugs, in scrubber, query compare no ID for lookup,
6061	  in dname validation for NS targets.
6062	- sets entry.key for new special allocs.
6063	- lognametypeclass can display unknown types and classes.
6064
60654 June 2007: Wouter
6066	- random selection of equally preferred nameserver targets.
6067	- reply info copy routine. Reuses existing code.
6068	- cache lameness in response handling.
6069	- do not touch qstate after worker_process_query because it may have
6070	  been deleted by that routine.
6071	- Prime response state.
6072	- Process target response state.
6073	- some memcmp changed to dname_compare for case preservation.
6074
60751 June 2007: Wouter
6076	- normalize incoming messages. Like unbound-java, with CNAME chain
6077	  checked, DNAME checked, CNAME's synthesized, glue checked.
6078	- sanitize incoming messages.
6079	- split msgreply encode functions into own file msgencode.c.
6080	- msg_parse to queryinfo/replyinfo conversion more versatile.
6081	- process_response, classify response, delegpt_from_message.
6082
608331 May 2007: Wouter
6084	- querytargets state.
6085	- dname_subdomain_c() routine.
6086	- server selection, based on RTT. ip6 is filtered out if not available,
6087	  and lameness is checked too.
6088	- delegation point copy routine.
6089
609030 May 2007: Wouter
6091	- removed FLAG_CD from message and rrset caches. This was useful for
6092	  an agnostic forwarder, but not for a sophisticated (trust value per
6093	  rrset enabled) cache.
6094	- iterator response typing.
6095	- iterator cname handle.
6096	- iterator prime start.
6097	- subquery work.
6098	- processInitRequest and processInitRequest2.
6099	- cache synthesizes referral messages, with DS and NSEC.
6100	- processInitRequest3.
6101	- if a request creates multiple subrequests these are all activated.
6102
610329 May 2007: Wouter
6104	- routines to lock and unlock array of rrsets moved to cache/rrset.
6105	- lookup message from msg cache (and copy to region).
6106	- fixed cast error in dns msg lookup.
6107	- message with duplicate rrset does not increase its TTLs twice.
6108	- 'qnamesize' changed to 'qname_len' for similar naming scheme.
6109
611025 May 2007: Wouter
6111	- Acknowledge use of unbound-java code in iterator. Nicer readme.
6112	- services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
6113	  rrset cache from module environment.
6114	- packed rrset key has type and class as easily accessible struct
6115	  members. They are still kept in network format for fast msg encode.
6116	- dns cache find_delegation routine.
6117	- iterator main functions setup.
6118	- dns cache lookup setup.
6119

6126
612723 May 2007: Wouter
6128	- outside network does precise timers for roundtrip estimates for rtt

6131	- iterator/iter_utils and iter_delegpt setup.
6132	- root hints.
6133

6136	  outbound entry to the module.
6137	- testbound support for new serviced queries.
6138	- test for retry to TCP cannot use testbound any longer.

6140	- fixes for no-locking compile.
6141	- mini_event timer precision and fix for change in timeouts during
6142	  timeout callback. Fix for fwd_three tests, performed nonexit query.
6143
614421 May 2007: Wouter
6145	- small comment on hash table locking.
6146	- outside network serviced queries, contain edns and tcp fallback,
6147	  and udp retries and rtt timing.
6148
614916 May 2007: Wouter
6150	- lruhash_touch() would cause locking order problems. Fixup in
6151	  lock-verify in case locking cycle is found.

6195	- EDNS read from query, used to make reply smaller.
6196	- advertised edns value constants.
6197	- EDNS BADVERS response, if asked for too high edns version.
6198	- EDNS extended error responses once the EDNS record from the query
6199	  has successfully been parsed.
6200
62014 May 2007: Wouter
6202	- msgreply sizefunc is more accurate.

6205	  alloc cache to store released keys.
6206	- alloc cache special_release() locks if necessary.
6207	- rrset trustworthiness type added.
6208	- thread keeps a scratchpad region for handling messages.

6223	- more dname unit tests.
6224	- message encoding creates truncated TC flagged messages if they do
6225	  not fit, and will leave out (whole)rrsets from additional if needed.
6226
62271 May 2007: Wouter
6228	- decompress query section, extremely lenient acceptance.
6229	  But only for answers from other servers, not for plain queries.
6230	- compression and decompression test cases.
6231	- some stats added.
6232	- example.conf interface: line is changed from 127.0.0.1 which leads
6233	  to problems if used (restricting communication to the localhost),
6234	  to a documentation and test address.
6235
623627 April 2007: Wouter
6237	- removed iov usage, it is not good for dns message encoding.

6413
64149 March 2007: Wouter

6430	  contention measurement.
6431
64326 March 2007: Wouter
6433	- Testbed works with threading (different machines, different options).
6434	- alloc work, does the special type.
6435
64362 March 2007: Wouter
6437	- do not compile fork funcs unless needed. Otherwise will give
6438	  type errors as their typedefs have not been enabled.
6439	- log shows thread numbers much more nicely (and portably).
6440	- even on systems with nonthreadsafe libevent signal handling,

6442	  Reloads will not work, and exit is not graceful.
6443	- start of alloc framework layout.
6444
64451 March 2007: Wouter
6446	- Signals, libevent and threads work well, with libevent patch and
6447	  changes to code (close after event_del).
6448	- set ipc pipes nonblocking.
6449
645027 February 2007: Wouter
6451	- ub_thread_join portable definition.
6452	- forking is used if no threading is available.
6453	  Tested, it works, since pipes work across processes as well.
6454	  Thread_join is replaced with waitpid.
6455	- During reloads the daemon will temporarily handle signals,
6456	  so that they do not result in problems.
6457	- Also randomize the outgoing port range for tests.
6458	- If query list is full, will stop selecting listening ports for read.
6459	  This makes all threads service incoming requests, instead of one.
6460	  No memory is leaking during reloads, service of queries, etc.
6461	- test that uses ldns-testns -f to test threading. Have to answer
6462	  three queries at the same time.
6463	- with verbose=0 operates quietly.
6464
646526 February 2007: Wouter
6466	- ub_random code used to select ID and port.
6467	- log code prints thread id.
6468	- unbound can thread itself, with reload(HUP) and quit working
6469	  correctly.
6470	- don't open pipes for #0, doesn't need it.
6471	- listens to SIGTERM, SIGQUIT, SIGINT (all quit) and SIGHUP (reload).
6472
647323 February 2007: Wouter
6474	- Can do reloads on sigHUP. Everything is stopped, and freed,
6475	  except the listening ports. Then the config file is reread.
6476	  And everything is started again (and listening ports if needed).
6477	- Ports for queries are shared.
6478	- config file added interface:, chroot: and username:.
6479	- config file: directory, logfile, pidfile. And they work too.
6480	- will daemonize by default now. Use -d to stay in the foreground.
6481	- got BSD random[256 state] code, made it threadsafe. util/random.
6482
648322 February 2007: Wouter
6484	- Have a config file. Removed commandline options, moved to config.

649120 February 2007: Wouter
6492	- Added locks code and pthread spinlock detection.

6494	- added yacc and lex configure, and config file parsing code.
6495	  also makedist.sh, and manpage.
6496	- put include errno.h in config.h
6497
649819 February 2007: Wouter
6499	- Created 0.0 svn tag.
6500	- added acx_pthread.m4 autoconf check for pthreads from
6501	  the autoconf archive. It is GPL-with-autoconf-exception Licensed.
6502	  You can specify --with-pthreads, or --without-pthreads to configure.
6503
650416 February 2007: Wouter
6505	- Updated testbed script, works better by using make on remote end.
6506	- removed check decls, we can compile without them.
6507	- makefile supports LIBOBJ replacements.
6508	- docs checks ignore compat code.
6509	- added util/mini-event.c and .h, a select based alternative used with
6510	  ./configure --with-libevent=no
6511	  It is limited to 1024 file descriptors, and has less features.
6512	- will not create ip6 sockets if ip6 not on the machine.
6513
651415 February 2007: Wouter
6515	- port to FreeBSD 4.11 Dec Alpha. Also works on Solaris 10 sparc64,
6516	  Solaris 9, FreeBSD 6, Linux i386 and OSX powerpc.
6517	- malloc rndstate, so that it is aligned for access.
6518	- fixed rbtree cleanup with postorder traverse.
6519	- fixed pending messages are deleted when handled.
6520	- You can control verbosity; default is not verbose, every -v
6521	  adds more verbosity.
6522
652314 February 2007: Wouter
6524	- Included configure.ac changes from ldns.
6525	- detect (some) headers before the standards check.
6526	- do not use isblank to test c99, since its not available on solaris9.
6527	- review of testcode.
6528		* entries in a RANGE are no longer reversed.
6529		* print name of file with replay entry parse errors.
6530	- port to OSX: cast to int for some prints of sizet.
6531	- Makefile copies ldnstestpkts.c before doing dependencies on it.
6532

65527 February 2007: Wouter
6553	- return answer with the same ID as query was sent with.
6554	- created udp forwarder test. I've done some effort to make it perform
6555	  quickly. After servers are created, no big sleep statements but
6556	  it checks the logfiles to see if servers have come up. Takes 0.14s.
6557	- set addrlen value when calling recvfrom.
6558	- comparison of addrs more portable.
6559	- LIBEVENT option for testbed to set libevent directory.
