649 - iana portlist update.
652 - Enable ECDHE for servers. Where available, use
653 SSL_CTX_set_ecdh_auto() for TLS-wrapped server configurations to
654 enable ECDHE. Otherwise, manually offer curve p256.
655 Client connections should automatically use ECDHE when available.
656 (thanks Daniel Kahn Gillmor)
659 - Allow certificate chain files to allow for intermediate certificates.
660 (thanks Daniel Kahn Gillmor)
663 - makedist produces sha1 and sha256 files for created binaries too.

699 - iana portlist update.
700 - documentation proposes ratelimit of 1000 (closer to what upstream
701 servers expect from us).
704 - DLV is going to be decommissioned. Advice to stop using it, and
705 put text in the example configuration and man page to that effect.
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>

717 30 April 2015: Wouter
718 - Unit test for type ANY synthesis.
720 22 April 2015: Wouter

731 - Add local-zone type inform_deny, that logs query and drops answer.
732 - Ratelimit does not apply to prefetched queries, and ratelimit-factor
733 is default 10. Repeated normal queries get resolved and with
734 prefetch stay in the cache.

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.

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.
826 - Document windows 8 tests.

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.
1208 - unbound-host -D enabled dnssec and reads root trust anchor from

1212 - Feature, unblock-lan-zones: yesno that you can use to make unbound
1213 perform 10.0.0.0/8 and other reverse lookups normally, for use if
1214 unbound is running service for localhost on localhost.
1217 - Updated create_unbound_ad_servers and unbound_cache scripts from
1218 Yuri Voinov in the source/contrib directory. Added
1219 warmup.cmd (and .sh): warm up the DNS cache with your MRU domains.
1222 - Implement draft-ietf-dnsop-rfc6598-rfc6303-01.
1223 - iana portlist updated.

1246 23 April 2014: Wouter
1247 - Patch from Jeremie Courreges-Anglas to use arc4random_uniform

1253 11 April 2014: Wouter

1256 - iana portlist updated.
1258 10 April 2014: Wouter
1259 - iana portlist updated.

1307 - iana portlist updated.
1309 20 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.
1317 14 February 2014: Wouter
1318 - Works on Minix (3.2.1).

1353 30 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.
1357 28 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.
1366 27 January 2014: Wouter
1367 - reuseport is attempted, then fallback to without on failure.
1369 24 January 2014: Wouter
1370 - Change unbound-event.h to use void* buffer, length idiom.
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
1374 lock contention on localzones.lock. It is changed to an rwlock.
1375 - so-reuseport: yesno option to distribute queries evenly over
1376 threads on Linux (Thanks Robert Edmonds).
1379 21 January 2014: Wouter
1380 - Fix #547: no trustanchor written if filesystem full, fclose checked.

1407 - Fix bug#537: compile python plugin without ldns library.
1410 - Fix bug#536: acl_deny_non_local and refuse_non_local added.
1413 - Patch from Neel Goyal to fix async id assignment if callback
1414 is called by libunbound in the mesh attach.

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.
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.
1443 - unbound-event.h is installed if configured --with-libevent. It
1444 contains low-level library calls, that use libevent's event_base
1445 and an ldns_buffer for the wire return packet to perform async
1446 resolution in the client's eventloop.
1449 - 1.4.21 tag created.

1513 - Fixup manpage syntax.
1516 - get_option and set_option support for log-time-ascii, python-script
1517 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
1518 immediately. The others are mostly useful for libunbound users.
1521 - get_option, set_option, unbound-checkconf -o and libunbound
1522 getoption and setoption support cache-min-ttl and cache-max-ttl.
1525 - Fix#501: forward-first does not recurse, when forward name is ".".
1526 - iana portlist update.
1527 - Max include depth is unlimited.
1530 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply
1531 patch to it to not fail when -Werror is also specified, from the
1533 - iana portlist update.

1848 19 June 2012: Wouter
1849 - --with-libunbound-only build option, only builds the library and
1850 not the daemon and other tools.
1852 18 June 2012: Wouter
1855 15 June 2012: Wouter

1923 21 March 2012: Wouter
1924 - new approach to NS fetches for DS lookup that works with
1925 cornercases, and is more robust and considers forwarders.
1927 19 March 2012: Wouter
1928 - iana portlist updated.
1929 - fix to locate nameservers for DS lookup with NS fetches.
1931 16 March 2012: Wouter
1932 - Patch for access to full DNS packet data in unbound python module
1935 9 March 2012: Wouter

1938 2 March 2012: Wouter
1939 - flush_infra cleans timeouted servers from the cache too.
1940 - removed warning from --enable-ecdsa.
1942 1 March 2012: Wouter

1952 for unbound-control.exe, and unbound-checkconf.exe.
1954 23 February 2012: Wouter
1955 - Fix to squelch 'network unreachable' errors from tcp connect in
1956 logs, high verbosity will show them.
1958 16 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.
1966 15 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.
1973 14 February 2012: Wouter
1974 - Fix sticky NS (ghost domain problem) if prefetch is yes.
1975 - iter forwards uses malloc inside for more dynamicity.
1977 13 February 2012: Wouter

1979 - iana portlist updated.
1981 10 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.
1987 9 February 2012: Wouter
1988 - Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
1990 8 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.
1999 3 February 2012: Wouter

2005 - iana portlist updated.
2007 1 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.
2013 30 January 2012: Wouter
2014 - Fix version-number in libtool to be version-info so it produces
2015 libunbound.so.2 like it should.
2017 26 January 2012: Wouter
2018 - Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.

2024 - Fix memset in test code.
2026 20 January 2012: Wouter
2027 - Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
2029 19 January 2012: Wouter
2030 - Fix to write key files completely to a temporary file, and if that

2033 18 January 2012: Wouter
2034 - tag 1.4.15rc1 created
2035 - updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
2037 17 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.
2042 12 January 2012: Wouter
2043 - bug#428: add ub_version() call to libunbound. API version increase,
2044 with (binary) backwards compatibility for the previous version.
2046 10 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
2050 - iana portlist updated.
2051 - uninitialised variable in reprobe for rtt blocked domains fixed.
2052 - lintfix and new flex output.
2054 2 January 2012: Wouter
2055 - Fix to randomize hash function, based on 28c3 congress, reported
2058 24 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
2063 - iana portlist updated.
2065 19 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

2081 - Fix to constrain signer_name to be a parent of the lookupname.
2083 5 December 2011: Wouter
2084 - Fix getaddrinfowithincludes on windows with fedora16 mingw32-gcc.
2085 - Fix warnings with gcc 4.6 in compat/inet_ntop.c.
2086 - Fix warning unused in compat/strptime.c.

2092 30 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).
2096 28 November 2011: Wouter
2097 - Fix quartile time estimate, it was too low, (thanks Jan Komissar).
2098 - iana ports updated.
2100 11 November 2011: Wouter
2101 - Makefile compat with SunOS make, BSD make and GNU make.

2121 - iana portlist updated.
2122 - fix -flto detection on Lion for llvm-gcc.
2124 31 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.
2128 27 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.

2133 - fix export-all-symbols on OSX.
2135 26 October 2011: Wouter

2141 24 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
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
2150 21 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.
2154 19 October 2011: Wouter
2155 - fix unbound-anchor for broken strptime on OSX lion, detected
2157 - Detect if GOST really works, openssl1.0 on OSX fails.
2158 - Implement ipv6%interface notation for scope_id usage.
2160 17 October 2011: Wouter
2161 - better documentation for inform_super (Thanks Yang Zhe).
2163 14 October 2011: Wouter
2164 - Fix for out-of-memory condition in libunbound (thanks
2167 13 October 2011: Wouter
2168 - Fix --enable-allsymbols, it depended on link specifics of the
2169 target platform, or fptr_wlist assertion failures could occur.
2171 12 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_ ).
2176 27 September 2011: Wouter
2177 - unbound.exe -w windows option for start and stop service.
2179 23 September 2011: Wouter
2180 - TCP-upstream calculates tcp-ping so server selection works if there
2183 20 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.
2188 16 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).
2200 15 September 2011: Wouter
2202 - trunk contains 1.4.14 in development.
2203 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
2205 12 September 2011: Wouter
2206 - Reverted dns EDNS backoff fix, it did not help and needs
2207 fragmentation fixes instead.
2210 7 September 2011: Wouter
2211 - Fix operation in ipv6 only (do-ip4: no) mode.
2213 6 September 2011: Wouter
2214 - fedora specfile updated.
2216 5 September 2011: Wouter
2219 2 September 2011: Wouter
2220 - iana portlist updated.
2222 26 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.
2231 24 August 2011: Wouter
2232 - Applied patch from Karel Slany that fixes a memory leak in the
2233 unbound python module, in string conversions.
2235 22 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.
2246 18 August 2011: Wouter
2247 - fix autoconf call in makedist crosscompile to RC or snapshot.
2249 17 August 2011: Wouter

2252 - iana portlist updated.
2254 10 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.
2259 9 August 2011: Wouter
2260 - patch from Tom Hendrikx fixes load of python modules.
2262 8 August 2011: Wouter

2265 1 August 2011: Wouter
2266 - Fix autoconf 2.68 warnings
2268 14 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.
2274 13 July 2011: Wouter
2275 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
2277 11 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).
2282 - 1.4.12rc1 tag created.
2285 - version number in example config file.
2286 - fix that --enable-static-exe does not complain about it unknown.
2288 30 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.
2299 23 June 2011: Wouter
2300 - Changed -flto check to support clang compiler.
2301 - tag 1.4.11rc3 created.
2303 17 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.
2309 16 June 2011: Wouter
2310 - log-queries: yesno option, default is no, prints querylog.
2311 - version is 1.4.11.
2313 14 June 2011: Wouter
2314 - Use -flto compiler flag for link time optimization, if supported.
2315 - iana portlist updated.
2317 12 June 2011: Wouter
2318 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
2320 10 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.
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.
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.
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.
2348 14 April 2011: Wouter
2349 - configure created with newer autoconf 2.66.
2351 12 April 2011: Wouter
2352 - bug#378: Fix that configure checks for ldns_get_random presence.
2354 8 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.
2362 29 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.
2367 24 March 2011: Wouter
2368 - iana portlist updated.
2372 17 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.
2376 10 March 2011: Wouter
2377 - tag 1.4.9 release candidate 1 created.

2382 1 March 2011: Wouter
2383 - Fix no ADflag for NXDOMAIN in NSEC3 optout. And wildcard in optout.
2384 - give config parse error for multiple names on a stub or forward zone.
2385 - updated ldns tarball to 1.6.9(todays snapshot).
2387 24 February 2011: Wouter
2388 - bug #361: Fix, time.elapsed variable not reset with stats_noreset.
2390 23 February 2011: Wouter
2391 - iana portlist updated.
2392 - common.sh to version 3.
2394 18 February 2011: Wouter

2404 - tpkg updated with common.sh for common functionality.
2406 7 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.
2411 28 January 2011: Wouter
2412 - Fix remove private address does not throw away entire response.
2414 24 January 2011: Wouter
2417 19 January 2011: Wouter
2418 - fix bug#349: no -L/usr for ldns.
2420 18 January 2011: Wouter
2421 - ldns 1.6.8 tarball included.
2424 17 January 2011: Wouter

2426 - iana portlist updated.
2428 14 January 2011: Wouter

2430 server, for type NS the TTL is not increased.
2432 13 January 2011: Wouter
2433 - Fix prefetch so it does not get stuck on old server for moved names.
2435 12 January 2011: Wouter
2436 - iana portlist updated.
2438 11 January 2011: Wouter
2439 - Fix insecure CNAME sequence marked as secure, reported by Bert

2447 - iana portlist updated.
2449 23 December 2010: Wouter
2450 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
2452 21 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
2459 It is not an option, because I see no use to turn the security off.
2460 - iana portlist updated.
2462 17 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.
2467 16 December 2010: Wouter

2482 - iana portlist updated.
2484 18 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
2489 17 November 2010: Wouter
2490 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
2491 - make test output nicer.
2493 15 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.
2498 9 November 2010: Wouter
2499 - unbound-anchor compiles with openssl 0.9.7.
2501 8 November 2010: Wouter
2502 - release tag 1.4.7.

2509 4 November 2010: Wouter
2510 - Use central entropy to seed threads.
2512 3 November 2010: Wouter
2513 - Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
2515 2 November 2010: Wouter
2519 1 November 2010: Wouter
2520 - GOST code enabled by default (RFC 5933).
2522 27 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.
2528 26 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.
2536 25 October 2010: Wouter
2537 - Configure errors if ldns is not found.
2539 22 October 2010: Wouter
2540 - Windows 7 fix for the installer.
2542 21 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.
2549 20 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.
2553 19 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
2561 18 October 2010: Wouter
2562 - iana portlist updated.
2564 13 October 2010: Wouter
2565 - Fix TCP so it uses a random outgoing-interface.
2566 - unbound-anchor handles ADDPEND keystate.
2568 11 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).
2575 1 October 2010: Wouter

2577 - Fix alloc_reg_release for longer uptime in out of memory conditions.
2579 28 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.
2586 24 September 2010: Wouter
2587 - bug#329: in example.conf show correct ipv4 link-local 169.254/16.
2589 23 September 2010: Wouter
2590 - unbound-anchor app, unbound requires libexpat (xml parser library).
2592 22 September 2010: Wouter
2593 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
2594 reverse ipv6 orchid prefix from builtin list.
2595 - iana portlist updated.
2597 17 September 2010: Wouter
2598 - DLV has downgrade protection again, because the RFC says so.
2599 - iana portlist updated.
2601 16 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.
2607 15 September 2010: Wouter
2608 - Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
2610 14 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.
2615 13 September 2010: Wouter
2616 - bug#327: Fix for cannot access stub zones until the root is primed.
2618 9 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.
2624 20 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.
2627 listen_pushback, query_info_allocqname, write_socket, send_packet,
2628 comm_point_set_cb_arg and listen_resume removed.
2630 19 August 2010: Wouter
2631 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
2632 Delegpt structures checked for duplicates always.
2633 No more nameserver lookups generated when depth is full anyway.
2634 - example.conf notes how to do DNSSEC validation and track the root.
2635 - iana portlist updated.
2637 18 August 2010: Wouter
2638 - Fix bug#322: configure does not respect CFLAGS on Solaris.
2639 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
2640 if use sun-cc, but some systems need different flags.
2642 16 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).
2648 13 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.
2653 9 August 2010: Wouter

2675 14 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.
2680 12 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.
2687 10 July 2010: Wouter
2688 - GOST enabled if SSL is recent and ldns has GOST enabled too.
2689 - ldns tarball updated.
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.
2698 - Neat function prototypes, unshadowed local declarations.
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.
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.
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.
2718 28 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
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.
2730 25 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++.
2736 23 June 2010: Wouter
2737 - iana portlist updated.
2738 - makedist upgraded cross compile openssl option, like this:
2739 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
2741 22 June 2010: Wouter
2742 - Unbound reports libev or libevent correctly in logs in verbose mode.
2743 - Fix to unload gost dynamic library module for leak testing.
2745 18 June 2010: Wouter
2746 - iana portlist updated.
2748 17 June 2010: Wouter
2749 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
2751 16 June 2010: Wouter
2752 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
2753 assertion was wrong.
2754 - updated ldns tarball.
2756 15 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
2764 - added documentation for the histogram printout to syslog.
2766 11 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.
2771 10 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.
2776 - iana portlist updated.
2777 - 1.4.5rc1 tag created.
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.
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.
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.
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.
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.
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.
2827 - EDNS timeout code will not fire if EDNS status already known.
2828 - EDNS failure not stored if EDNS status known to work.
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
2836 - Fix comments in iter_utils:dp_is_useless.
2839 - Fix various compiler warnings from the clang llvm compiler.
2840 - iana portlist updated.
2843 - Fix bug#308: spelling error in variable name in parser and lexer.
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.
2851 29 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).
2856 28 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).
2861 27 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.
2869 26 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.
2884 23 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
2895 22 April 2010: Wouter
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 ...'.
2901 16 April 2010: Wouter
2902 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
2905 15 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.
2910 9 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
2917 8 April 2010: Wouter
2918 - Fix validation of queries with wildcard names (*.example).
2920 6 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.
2927 1 April 2010: Wouter
2928 - iana portlist updated.
2930 24 March 2010: Wouter
2931 - unbound control flushed items are not counted when flushed again.
2933 23 March 2010: Wouter
2934 - iana portlist updated.
2936 22 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

2955 - for NSEC3 check if signatures are cached.
2957 15 March 2010: Wouter
2958 - unit test for util/regional.c.
2960 12 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.

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

2985 - tag 1.4.2 created.
2986 - trunk is 1.4.3 in development.
2987 - --enable-alloc-lite debug option.
2989 8 March 2010: Wouter

2997 - iana portlist updated.
2999 1 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.

3017 - Also delete potential poison references from additional.
3018 - Fix: no classification of a forwarder as lame, throw away instead.
3020 23 February 2010: Wouter
3021 - libunbound ub_ctx_get_option() added.
3022 - unbound-control set_option and get_option commands.
3023 - iana portlist updated.
3025 18 February 2010: Wouter
3026 - A little more strict DS scrubbing.
3027 - No more blacklisting of unresponsive servers, a 2 minute timeout
3029 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.

3040 16 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.
3044 15 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).
3050 12 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.
3057 11 February 2010: Wouter
3058 - ldns tarball update for long label length syntax error fix.
3059 - iana portlist updated.

3085 14 January 2010: Wouter
3086 - Fixup ldns detection to also check for header files.
3088 13 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).
3093 12 January 2010: Wouter
3094 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
3096 8 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.
3107 7 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.
3113 6 January 2010: Wouter
3114 - iana portlist updated.

3145 9 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.
3154 8 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.
3161 7 December 2009: Wouter
3162 - Bug#287: Fix segfault when unbound-control remove nonexistent local
3163 data. Added check to tests.
3165 1 December 2009: Wouter

3179 23 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.
3184 20 November 2009: Wouter

3205 long ANY mix cases, which fixes validation failures.
3207 12 November 2009: Wouter
3208 - iana portlist updated.
3209 - fix manpage errors reported by debian lintian.
3211 - fixup very long vallog2 level error strings.

3219 to combine well when combined with DLV and a particular failure.
3220 - Fixed unbound-control -h output about argument optionality.
3223 5 November 2009: Wouter

3225 - better error text for multiple domain keys in one autotrust file.
3227 2 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.

3241 - ldns tarball updated (which also enables rsasha256 support).
3243 27 October 2009: Wouter
3244 - iana portlist updated.
3246 8 October 2009: Wouter
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).
3257 7 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.

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
3275 6 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.
3280 5 October 2009: Wouter
3281 - first validation failure retry code. Retries for data failures.
3284 2 October 2009: Wouter
3285 - improve 5011 modularization.
3286 - fix unbound-host so -d can be given before -C.

3293 - review fixes to comments, removed unused code.
3295 25 September 2009: Wouter
3296 - so-rcvbuf: 4m option added. Set this on large busy servers to not
3297 drop the occasional packet in spikes due to full socket buffers.
3298 netstat -su keeps a counter of UDP dropped due to full buffers.
3299 - review of validator/autotrust.c, small fixes and comments.
3301 23 September 2009: Wouter
3302 - 5011 query failed counts verification failures, not lookup failures.
3303 - 5011 probe failure handling fixup.
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.
3308 22 September 2009: Wouter
3309 - autotrust test with algorithm rollover, new ordering of checks
3310 assists in orderly rollover.
3311 - autotrust test with algorithm rollover to unknown algorithm.
3312 checks if new keys are supported before adding them.
3313 - autotrust test with trust point revocation, becomes unsigned.
3314 - fix DNSSEC-missing-signature detection for minimal responses
3315 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
3317 18 September 2009: Wouter
3318 - autotrust tests, fix trustpoint timer deletion code.
3319 fix count of valid anchors during missing remove.
3320 - autotrust: pick up REVOKE even if not signed with known other keys.

3331 15 September 2009: Wouter
3332 - iana portlist updated.
3334 10 September 2009: Wouter
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.
3341 9 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
3344 keep messages bogus in the cache for too long.
3345 - regression test for that bug.
3346 - documented that load_cache is meant for debugging.
3348 8 September 2009: Wouter
3349 - fixup printing errors when load_cache, they were printed to the

3360 - Changes to make unbound work with libevent-2.0.3 alpha. (in
3361 configure detection due to new ssl dependency in libevent)
3362 - do not call sphinx for documentation when python is disabled.
3363 - remove EV_PERSIST from libevent timeout code to make the code

3431 - autotrust work, split up DS verification of DNSKEYs.
3433 14 August 2009: Wouter
3434 - unbound-control lookup prints out infra cache information, like RTT.
3435 - Fix bug in DLV lookup reported by Amanda from Secure64.
3436 It could sometimes wrongly classify a domain as unsigned, which
3437 does not give the AD bit on replies.

3440 - autotrust read anchor files. locked trust anchors.
3442 12 August 2009: Wouter

3508 - iana portlist updated.
3509 - configure changes and ldns update for mingw32 crosscompile.
3511 13 July 2009: Wouter

3536 29 June 2009: Wouter
3537 - ldns trunk r2959 imported as tarball, because of solaris cc compile
3538 support for c99. r2960 for better configure.

3541 avoid dropped packets at routers.
3543 26 June 2009: Wouter
3544 - Fix EDNS fallback when EDNS works for short answers but long answers
3547 22 June 2009: Wouter

3559 18 June 2009: Wouter
3560 - Fix of message parse bug where (specifically) an NSEC and RRSIG
3561 in the wrong order would be parsed, but put wrongly into internal
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.
3569 17 June 2009: Wouter
3570 - CREDITS entry for cz.nic, sponsoring a 'summer of code' that was

3574 - Fixup opportunistic target query generation to it does not
3575 generate queries that are known to fail.
3576 - Touchup on munin total memory report.
3577 - messages picked out of the cache by the iterator are checked
3578 if their cname chain is still correct and if validation status
3579 has to be reexamined.
3581 15 June 2009: Wouter
3582 - iana portlist updated.
3584 14 June 2009: Wouter
3585 - Fixed bug where cached responses would lose their security

3587 lookups. Reported by Hauke Lampe.
3589 13 June 2009: Wouter
3590 - bug #254. removed random whitespace from example.conf.
3592 12 June 2009: Wouter
3593 - Fixup potential wrong NSEC picked out of the cache.
3594 - If unfulfilled callbacks are deleted they are called with an error.
3595 - fptr wlist checks for mesh callbacks.
3596 - fwd above stub in configuration works.
3598 11 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.
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.
3618 - Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
3619 inadvertant behaviour.

3621 - 1.3.1 development in svn trunk.
3622 - iana portlist updated.

3624 - help compiler figure out aliasing in priv_rrset_bad() routine.
3625 - fail to configure with python if swig is not found.
3626 - unbound_munin_ in contrib uses ps to show rss if sbrk does not work.
3629 - fixup bad free() when wrongly encoded DSA signature is seen.
3630 Reported by Paul Wouters.
3631 - review comments from Matthijs.
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.
3641 - fixup doc bug in README reported by Matthew Dempsky.
3644 - update iana port list
3645 - update ldns lib tarball
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.
3659 - Thanks again to Brett Carr, found an assertion that was not true.
3660 Assertion checked if recursion parent query still existed.
3662 29 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.

3730 - clock skew checks in unbound, config statements.
3731 - nxdomain ttl considerations in requirements.txt
3733 3 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.
3739 2 April 2009: Wouter
3740 - pyunbound (libunbound python plugin) compiles using libtool.

3746 - python module test package.
3748 1 April 2009: Wouter
3749 - suppress errors when trying to contact authority servers that gave

3804 - defaults for windows baked into configure.ac (used if on mingw).
3806 18 March 2009: Wouter
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
3813 insecure regardless of chain of trust DSs or DLVs. The inverse
3816 17 March 2009: Wouter

3833 12 March 2009: Wouter
3834 - log to App.logs on windows prints executable identity.
3836 - munin plugin fix benign locking error printout.
3837 - anchor-update for windows, called every 24 hours; unbound reloads.
3839 11 March 2009: Wouter

3843 default install location.
3844 - on windows logging to the Application logbook works (as a service).
3845 - fix RUN_DIR on windows compile setting in makedist.
3846 - windows registry has Software\Unbound\ConfigFile element.

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
3904 security is provided by pgp signature.
3906 18 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.
3914 13 February 2009: Wouter
3915 - forwarder information now per-thread duplicated.
3916 This keeps it read only for speed, with no locking necessary.
3917 - forward command for unbound control to change forwarders to use
3919 - document that unbound-host reads no config file by default.
3920 - updated iana portlist.
3922 12 February 2009: Wouter
3923 - call setusercontext if available (on BSD).
3924 - small refactor of stats clearing.

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.
3954 5 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
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.
3974 4 February 2009: Wouter

3985 available (network unreachable). Debug still printed on high
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
3993 15 January 2009: Wouter
3994 - bug #229: fixup configure checks for compilation with Solaris
3995 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc

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 ).
4012 13 January 2009: Wouter
4013 - fixed bug in lameness marking, removed printouts.

4017 - 1.2.1 feature: stops resolving AAAAs promiscuously when they
4018 are in the negative cache.
4020 12 January 2009: Wouter
4021 - fixed bug in infrastructure lameness cache, did not lowercase
4022 name of zone to hash when setting lame.
4023 - lameness debugging printouts.
4025 9 January 2009: Wouter
4026 - created svn tag for 1.2.0 release.
4027 - svn trunk contains 1.2.1 version number.

4032 - new version of ldns-trunk (today) included as tarball, fixed
4033 bug #224, building with -j race condition.
4034 - remove possible race condition in the test for race conditions.
4036 7 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.
4043 6 January 2009: Wouter

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
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.

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.

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.
4080 16 December 2008: Wouter
4081 - follow makedist improvements from ldns, for maintainers prereleases.
4082 - snapshot version uses _ not - to help rpm distinguish the
4085 11 December 2008: Wouter
4086 - better fix for bug #219: use LOG_NDELAY with openlog() call.
4087 Thanks to Tamas Tevesz.
4089 9 December 2008: Wouter
4090 - bug #221 fixed: unbound checkconf checks if key files exist if
4091 remote control is enabled. Also fixed NULL printf when not chrooted.
4092 - iana portlist updated.
4094 3 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.
4105 1 December 2008: Wouter
4106 - SElinux policy files in contrib/selinux for the unbound daemon,
4107 by Paul Wouters and Adam Tkac.
4109 25 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.
4117 24 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.
4126 21 November 2008: Wouter
4127 - fixed tcp accept, errors were printed when they should not.
4128 - unbound-control-setup.sh removes read/write permissions other
4129 from the keys it creates (as suggested by Dmitriy Demidov).
4131 20 November 2008: Wouter
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.
4136 - tag 1.1.1 created in svn.
4137 - trunk label is 1.1.2
4139 19 November 2008: Wouter
4140 - bug #219: fixed so that syslog which delays opening until the first
4141 log line is written, gets a log line while not chroot'ed yet.
4143 18 November 2008: Wouter
4144 - iana portlist updated.
4145 - removed cast in unit test debug print that was not 64bit safe.
4146 - trunk back to 1.1.0; copied to tags 1.1.0 release.
4147 - trunk to has version number 1.1.1 again.
4148 - in 1.1.1; make clean nicer. grammar in manpage.
4150 17 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.
4161 14 November 2008: Wouter

4169 - neater comments in worker.h.
4170 - removed doc/plan and updated doc/TODO.
4171 - silenced EHOSTDOWN (verbosity 2 or higher to see it).
4172 - review comments from Jelte, Matthijs. Neater code.
4174 12 November 2008: Wouter
4175 - add unbound-control manpage to makedist replace list.
4177 11 November 2008: Wouter
4178 - unit test for negative cache, stress tests the refcounting.
4179 - fix for refcounting error that could cause fptr_wlist fatal exit
4180 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
4181 Attila Nagy for testing).
4182 - nicer comments in cachedump about failed RR to string conversion.
4183 - fix 32bit wrap around when printing large (4G and more) mem usage
4184 for extended statistics.
4186 10 November 2008: Wouter

4197 - dname_priv must decompress the name before comparison.
4198 - iana portlist updated.
4200 5 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
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.
4216 4 November 2008: Wouter
4217 - fixed -Wwrite-strings warnings that result in better code.
4219 3 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).
4229 23 October 2008: Wouter
4230 - a little more debug info for failure on signer names. prints names.
4232 22 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.
4243 21 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.
4250 20 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.
4268 17 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.
4275 16 October 2008: Wouter
4276 - Fixup negative TTL values appearing (reported by Attila Nagy).
4278 15 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.
4284 14 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.
4296 13 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
4300 - iana port list update.
4301 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
4303 10 October 2008: Wouter
4304 - fixup tests - the negative cache contained the correct NSEC3s for
4305 two tests that are supposed to fail to validate.
4307 9 October 2008: Wouter
4308 - negative cache caps max iterations of NSEC3 done.
4309 - NSEC3 negative cache for qtype DS works.
4311 8 October 2008: Wouter
4312 - NSEC negative cache for DS.
4314 6 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.
4320 2 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.
4328 30 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"
4338 29 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.
4343 26 September 2008: Wouter
4344 - tests for remote-control.
4345 - small memory leak in exception during remote control fixed.

4415 - private-address and private-domain config option read, stored.
4417 2 September 2008: Wouter
4418 - DoS protection features. Queries are jostled out to make room.
4419 - testbound can pass time, increasing the internal timer.
4420 - do not mark unsigned additionals bogus, leave unchecked, which
4423 1 September 2008: Wouter
4424 - disallow nonrecursive queries for cache snooping by default.
4425 You can allow is using access-control: <subnet> allow_snoop.

4434 28 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.
4440 27 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.

4444 chroot and drop permissions.
4445 - config option to set size of aggressive negative cache,
4447 - bug#203 fixed: dlv has been implemented.
4449 26 August 2008: Wouter

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.
4605 18 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.

4614 17 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.

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
4684 - update of the ldns tarball to current ldns svn version (fix 181).

4776 It will detect and convert when necessary.
4778 14 April 2008: Wouter
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.

4784 - and check first sig byte for the encoding type.
4786 11 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.
4790 - created 256-port ephemeral space for the OS, 59802 available.
4791 - fixup consistency of port_if out array during heavy use.
4793 10 April 2008: Wouter

4795 - added log file statistics perl script to contrib.
4796 - automatic iana ports update from makefile. 60058 available.
4798 9 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.
4808 8 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.
4812 27 March 2008: Wouter
4813 - documented /dev/random symlink from chrootdir as FAQ entry.
4815 26 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.
4821 25 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.
4833 7 March 2008: Wouter
4834 - -C config feature for harvest program.
4835 - harvest handles CNAMEs too.
4837 5 March 2008: Wouter
4838 - patch from Hugo Koji Kobayashi for iterator logs spelling.
4840 4 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.
4848 3 March 2008: Wouter
4849 - Create 0.10 svn tag.
4850 - 0.11 version in trunk.
4851 - indentation nicer.
4853 29 February 2008: Wouter
4854 - documentation update.
4855 - fixup port to Solaris of perf test tool.
4856 - updated ldns-tarball with decl-after-statement fixes.
4858 28 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).
4867 27 February 2008: Wouter
4868 - option to use caps for id randomness.
4869 - config file option use-caps-for-id: yes
4870 - harvest debug tool
4872 26 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.
4878 25 February 2008: Wouter
4879 - delay utility works. Gets decent thoughput too (>20000).
4881 22 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
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.
4902 21 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.
4908 20 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
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).
4918 19 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
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.
4940 18 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
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.
4954 15 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.
4960 14 February 2008: Wouter
4961 - start without a config file (will complain, but start with
4963 - perf test program works.

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.
4989 - layout of manpages, spelling fix in header, manpages process by
4990 makedist, list asynclook and tcpstream tests as ldns-testns
4993 7 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
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.
5001 6 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.

5014 - fixup Makefile strip command and libunbound docs typo.
5016 31 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.
5021 30 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.
5029 28 January 2008: Wouter
5030 - fixup uninit use of buffer by libunbound (query id, flags) for
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
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).
5044 25 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.
5062 24 January 2008: Wouter
5063 - tested the cancel() function.
5064 - asynclook -c (cancel) feature.

5070 - new calls to set forwarding added to header and docs.
5072 23 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() ).
5079 22 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.
5087 21 January 2008: Wouter
5088 - libworker work, netevent raw commpoints, write_msg, serialize.
5090 18 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.
5101 17 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.
5109 16 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'.
5115 15 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.
5123 14 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.
5131 11 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
5136 - memory sizes can be given with 'k', 'Kb', or M or G appended.
5138 10 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.
5146 9 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.
5150 8 January 2008: Wouter
5151 - print median and quartiles with extensive logging.
5153 4 January 2008: Wouter
5154 - document misconfiguration in private network.
5156 2 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.
5161 7 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.
5172 6 December 2007: Wouter
5173 - library resolution works in foreground mode, unbound-host app
5175 - unbound-host prints rdata using ldns.
5176 - unbound-host accepts trust anchors, and prints validation
5177 information when you give -v.
5179 5 December 2007: Wouter
5180 - locking in context_new() inside the function.
5181 - setup of libworker.
5183 4 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.

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.
5207 3 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.
5217 30 November 2007: Wouter
5218 - makefile that creates libunbound.la, basic file or libunbound.a
5219 when creating static executables (no libtool).
5222 29 November 2007: Wouter
5223 - 0.9 public API start.
5225 28 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
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.
5247 27 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.
5256 22 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.
5272 21 November 2007: Wouter
5273 - local zone internal data setup.
5275 20 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.
5279 19 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.
5292 16 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.
5300 15 November 2007: Wouter
5301 - review fixups from Jelte.
5303 14 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.
5309 13 November 2007: Wouter
5310 - remove debug print.
5311 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
5313 12 November 2007: Wouter
5314 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
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.
5320 9 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.
5327 8 November 2007: Wouter
5328 - Fixup chroot and drop user privileges.
5329 - new L root ip address in default hints.
5331 1 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.
5343 31 October 2007: Wouter
5344 - cache-max-ttl config option.
5345 - building outside sourcedir works again.
5346 - defaults more secure:
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.
5356 30 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.
5363 23 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.
5375 22 October 2007: Wouter
5376 - added donotquerylocalhost config option. Can be turned off for
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.
5386 19 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,
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).
5402 18 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,
5419 - make unit test cleanly free memory.
5421 17 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
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).
5442 16 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.
5456 15 October 2007: Wouter
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.
5464 8 October 2007: Wouter
5465 - --disable-rpath option in configure for 64bit systems with
5466 several dynamic lib dirs.
5468 7 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.
5472 6 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.
5482 5 October 2007: Wouter
5483 - function pointer whitelist.
5485 4 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.
5491 3 October 2007: Wouter
5492 - fix for multiple empty nonterminals, after multiple DSes in the
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).
5503 1 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).
5508 28 September 2007: Wouter
5509 - test case for unbound-checkconf, fixed so it also checks the
5510 interface: statements.
5512 26 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.
5518 25 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.
5526 24 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
5531 - signit can generate NSEC3 hashes, for generating tests.
5532 - multiple nsec3 parameters in message test.
5533 - too high nsec3 iterations becomes insecure test.
5535 21 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.
5546 20 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.
5556 19 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.
5565 18 September 2007: Wouter
5566 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
5567 - validator prints subtype classification for debug.
5569 17 September 2007: Wouter
5570 - NSEC3 hash cache unit test.
5571 - validator nsec3 nameerror test.
5573 14 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.
5581 13 September 2007: Wouter
5582 - nsec3 find matching and covering, ce proof, prove namerror msg.
5584 12 September 2007: Wouter
5585 - fixup of manual page warnings, like for NSD bugreport.
5586 - nsec3 work, config, max iterations, filter, and hash cache.
5588 6 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.
5593 - pthread_rwlock type is optional, in case of old pthread libs.
5595 5 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,
5609 - configure option for memory allocation debugging.
5610 - port configure option for memory allocation to solaris10.
5612 4 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
5628 3 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
5638 - tool too summarize allocations per code line.
5640 31 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.
5648 30 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.
5659 29 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
5668 28 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
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
5689 27 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
5694 - do not store referral in msg cache for nonRD queries.
5695 - store verification status in the rrset cache to speed up future
5697 - mark rrsets indeterminate and insecure if they are found to be so.
5698 and store this in the cache.
5700 24 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-
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).
5715 23 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
5721 - refuse to follow wildcarded DNAMEs when validating.
5722 But you can query for qtype ANY, or qtype DNAME and validate that.
5724 22 August 2007: Wouter
5726 - review - use val_error().
5728 21 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.
5738 20 August 2007: Wouter
5739 - validate and positive validation, positive wildcard NSEC validation.
5740 - nodata validation, nxdomain validation.
5742 18 August 2007: Wouter
5743 - process DNSKEY response in FINDKEY state.
5745 17 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.
5751 16 August 2007: Wouter
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
5757 - fixup canonical compare byfield routine, fix bug and also neater.
5758 - fixed iterator response type classification for queries of type
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.
5765 15 August 2007: Wouter
5766 - crypto calls to verify signatures.
5767 - unit test for rrsig verification.
5769 14 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
5780 - fixed error in parser with backwards rrsig references.
5781 - mark cycle targets for iterator did not have CD flag so failed
5784 13 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.
5791 10 August 2007: Wouter
5792 - malloc and free overrides that track total allocation and frees.
5793 for memory debugging.
5794 - work on canonical sort.
5796 9 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.
5804 8 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
5810 7 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.
5816 - val_sigcrypt file for validator signature checks.
5818 6 August 2007: Wouter
5819 - key cache for validator.
5820 - moved isroot and dellabel to own dname routines, with unit test.
5822 3 August 2007: Wouter
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.
5831 2 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.
5841 1 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.
5847 31 July 2007: Wouter
5851 30 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.
5860 27 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.
5866 26 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.
5872 25 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.
5879 24 July 2007: Wouter
5880 - Example section in config manual.
5881 - Addr stored for range and moment in replay.
5883 20 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).
5898 19 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.
5905 18 July 2007: Wouter
5906 - do not query addresses, 127.0.0.1, and ::1 by default.
5908 17 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
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.
5920 27 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.
5931 26 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.
5938 25 June 2007: Wouter
5940 - error encode routine for ease.
5942 22 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.
5953 21 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.
5961 20 June 2007: Wouter
5962 - new -C option to enable coredumps after forking away.
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.
5972 19 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
5982 - fixup encoding of very short edns buffer sizes, now sets TC bit.
5983 - config options harden-short-bufsize and harden-large-queries.
5985 18 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.
5990 15 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
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
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).
6002 14 June 2007: Wouter
6003 - num query targets was > 0 , not >= 0 compared, so that fetch
6004 policy of 0 did nothing.
6006 13 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.
6014 12 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).
6022 11 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.
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.

6229 But only for answers from other servers, not for plain queries.
6230 - compression and decompression test cases.
6232 - example.conf interface: line is changed from 127.0.0.1 which leads

6419 - checklocks zeroes its destroyed lock after checking memory areas.
6420 - unit test for alloc.

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.
