360 - Disable minimal-responses in ipsecmod unit tests.
361 - Added serve-expired-ttl and serve-expired-ttl-reset options.
363 27 August 2018: Wouter
364 - Set defaults to yes for a number of options to increase speed and
365 resilience of the server. The so-reuseport, harden-below-nxdomain,
366 and minimal-responses options are enabled by default. They used
367 to be disabled by default, waiting to make sure they worked. They
368 are enabled by default now, and can be disabled explicitly by
369 setting them to "no" in the unbound.conf config file. The reuseport
370 and minimal options increases speed of the server, and should be
371 otherwise harmless. The harden-below-nxdomain option works well
372 together with the recently default enabled qname minimisation, this
373 causes more fetches to use information from the cache.
374 - next release is called 1.8.0.
375 - Fix lintflags for lint on FreeBSD.
377 22 August 2018: George

395 17 August 2018: Wouter
396 - Set libunbound to increase current, because the libunbound change
397 to the event callback function signature. That needs programs,
398 that use it, to recompile against the new header definition.
399 - print servfail info to log as error.
400 - added more servfail printout statements, to the iterator.

429 - Make capsforid fallback QNAME minimisation aware.
431 7 August 2018: Wouter

436 'RestrictAddressFamilies' (without it IPV6 can't work). From
438 - Patch to implement tcp-connection-limit from Jim Hague (Sinodun).
439 This limits the number of simultaneous TCP client connections
440 from a nominated netblock.
441 - make depend, yacc, lex, doc, headers. And log the limit exceeded
442 message only on high verbosity, so as to not spam the logs when

1069 - [dnscrypt] prevent dnscrypt-secret-key, dnscrypt-provider-cert
1071 - [dnscrypt] introduce dnscrypt-provider-cert-rotated option,
1073 This option allows handling multiple cert/key pairs while only
1074 distributing some of them.
1075 In order to reliably match a client magic with a given key without
1076 strong assumption as to how those were generated, we need both key and
1077 cert. Likewise, in order to know which ES version should be used.
1078 On the other hand, when rotating a cert, it can be desirable to only
1079 serve the new cert but still be able to handle clients that are still
1080 using the old certs's public key.
1081 The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not
1082 publish the cert as part of the DNS's provider_name's TXT answer.

2502 for secure domain name system traffic.
2503 If you used to rely on the older default of port 443, you have
2504 to put a clause in unbound.conf for that. The new value is likely
2505 going to be the standardised port number for this traffic.

2630 - documentation proposes ratelimit of 1000 (closer to what upstream
2631 servers expect from us).
2634 - DLV is going to be decommissioned. Advice to stop using it, and
2635 put text in the example configuration and man page to that effect.
2638 - Change syntax of particular validator error to be easier for
2639 machine parse, swap rrset and ip adres info so it looks like:
2640 validation failure <www.example.nl. TXT IN>: signature crypto
2641 failed from 2001:DB8:7:bba4::53 for <*.example.nl. NSEC IN>
2644 - caps-whitelist in unbound.conf allows whitelist of loadbalancers

2661 - Add local-zone type inform_deny, that logs query and drops answer.

2683 7 April 2015: Wouter
2684 - Libunbound skips dos-line-endings from etc/hosts.
2685 - Unbound exits with a fatal error when the auto-trust-anchor-file
2686 fails to be writable. This is seconds after startup. You can
2687 load a readonly auto-trust-anchor-file with trust-anchor-file.
2688 The file has to be writable to notice the trust anchor change,
2689 without it, a trust anchor change will be unnoticed and the system
2690 will then become inoperable.
2691 - unbound-control list_insecure command shows the negative trust
2692 anchors currently configured, patch from Jelte Jansen.

2703 - Fix #657: libunbound(3) recommends deprecated
2704 CRYPTO_set_id_callback.
2705 - If unknown trust anchor algorithm, and libressl is used, error
2706 message encourages upgrade of the libressl package.
2708 23 March 2015: Wouter
2709 - Fix segfault on user not found at startup (from Maciej Soltysiak).
2711 20 March 2015: Wouter

2746 4 March 2015: Wouter
2747 - Patch from Brad Smith that syncs compat/getentropy_linux with
2748 OpenBSD's version (2015-03-04).
2749 - 0x20 fallback improved: servfail responses do not count as missing
2750 comparisons (except if all responses are errors),
2751 inability to find nameservers does not fail equality comparisons,
2752 many nameservers does not try to compare more than max-sent-count,
2753 parse failures start 0x20 fallback procedure.
2754 - store caps_response with best response in case downgrade response
2755 happens to be the last one.
2756 - Document windows 8 tests.

3073 11 July 2014: Wouter
3074 - arc4random in compat/ and getentropy, explicit_bzero, chacha for
3075 dependencies, from OpenBSD. arc4_lock and sha512 in compat.
3076 This makes arc4random available on all platforms, except when

3105 - Add AAAA for B root server to default root hints.
3108 - Remove unused define from iterator.h
3111 - Fixup sldns_enum_edns_option typedef definition.
3114 - Code cleanup patch from Dag-Erling Smorgrav, with compiler issue
3115 fixes from FreeBSD's copy of Unbound, he notes:
3116 Generate unbound-control-setup.sh at build time so it respects
3117 prefix and sysconfdir from the configure script. Also fix the
3118 umask to match the comment, and the comment to match the umask.
3119 Add const and static where needed. Use unions instead of
3120 playing pointer poker. Move declarations that are needed in
3121 multiple source files into a shared header. Move sldns_bgetc()
3122 from parse.c to buffer.c where it belongs. Introduce a new
3123 header file, worker.h, which declares the callbacks that
3124 all workers must define. Remove those declarations from
3125 libworker.h. Include the correct headers in the correct places.
3126 Fix a few dummy callbacks that don't match their prototype.
3127 Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK.
3128 Remove a useless printf which breaks reproducible builds.
3129 Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
3130 no longer used. Add unbound-control-setup.sh to the list of
3131 generated files. The prototype for libworker_event_done_cb()
3132 needs to be moved from libunbound/libworker.h to
3133 libunbound/worker.h.
3134 - Fixup out-of-directory compile with unbound-control-setup.sh.in.
3138 - unbound-host -D enabled dnssec and reads root trust anchor from
3139 the default root key file that was compiled in.
3142 - Feature, unblock-lan-zones: yesno that you can use to make unbound
3143 perform 10.0.0.0/8 and other reverse lookups normally, for use if
3144 unbound is running service for localhost on localhost.
3147 - Updated create_unbound_ad_servers and unbound_cache scripts from
3148 Yuri Voinov in the source/contrib directory. Added
3149 warmup.cmd (and .sh): warm up the DNS cache with your MRU domains.
3152 - Implement draft-ietf-dnsop-rfc6598-rfc6303-01.
3153 - iana portlist updated.
3156 - Contrib windows scripts from Yuri Voinov added to src/contrib:
3157 create_unbound_ad_servers.cmd: enters anti-ad server lists.
3158 unbound_cache.cmd: saves and loads the cache.
3159 - Added unbound-control-setup.cmd from Yuri Voinov to the windows
3160 unbound distribution set. It requires openssl installed in %PATH%.
3163 - Change MAX_SENT_COUNT from 16 to 32 to resolve some cases easier.
3166 - More #567: remove : from output of stub and forward lists, this is
3169 29 April 2014: Wouter
3170 - iana portlist updated.
3171 - Add unbound-control flush_negative that flushed nxdomains, nodata,
3172 and errors from the cache. For dnssec-trigger and NetworkManager,
3173 fixes cases where network changes have localdata that was already
3174 negatively cached from the previous network.
3176 23 April 2014: Wouter
3177 - Patch from Jeremie Courreges-Anglas to use arc4random_uniform
3178 if available on the OS, it gets entropy from the OS.
3180 15 April 2014: Wouter
3181 - Fix compile with libevent2 on FreeBSD.
3183 11 April 2014: Wouter
3184 - Fix #502: explain that do-ip6 disable does not stop AAAA lookups,
3185 but it stops the use of the ipv6 transport layer for DNS traffic.
3186 - iana portlist updated.
3188 10 April 2014: Wouter
3189 - iana portlist updated.
3190 - Patch from Hannes Frederic Sowa for Linux 3.15 fragmentation
3191 option for DNS fragmentation defense.
3192 - Document that dump_requestlist only prints queries from thread 0.
3193 - unbound-control stats prints num.query.tcpout with number of TCP
3194 outgoing queries made in the previous statistics interval.

3196 +i annotation in output of list_forwards, also for list_stubs
3197 (for NetworkManager integration.)
3198 - Fix #554: use unsigned long to print 64bit statistics counters on
3200 - Fix #558: failed prefetch lookup does not remove cached response
3201 but delays next prefetch (in lieu of caching a SERVFAIL).
3202 - Fix #545: improved logging, the ip address of the error is printed
3203 on the same log-line as the error.
3205 8 April 2014: Wouter
3206 - Fix #574: make test fails on Ubuntu 14.04. Disabled remote-control
3207 in testbound scripts.
3208 - iana portlist updated.
3210 7 April 2014: Wouter
3211 - C.ROOT-SERVERS.NET has an IPv6 address, and we updated the root
3212 hints (patch from Anand Buddhdev).
3213 - Fix #572: Fix unit test failure for systems with different
3216 28 March 2014: Wouter
3217 - Fix #569: do_tcp is do-tcp in unbound.conf man page.
3219 25 March 2014: Wouter
3220 - Patch from Stuart Henderson to build unbound-host man from .1.in.
3222 24 March 2014: Wouter

3229 10 March 2014: Wouter
3230 - Fix bug#561: contrib/cacti plugin did not report SERVFAIL rcodes
3231 because of spelling. Patch from Chris Coates.
3233 27 February 2014: Wouter
3236 21 February 2014: Wouter
3237 - iana portlist updated.
3239 20 February 2014: Matthijs
3240 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
3241 received. This is okay according 4035, but not after revising
3242 existence in 4592. NSEC empty non-terminals exist and thus the
3243 RCODE should have been NOERROR. If this occurs, and the RRsets
3244 are secure, we set the RCODE to NOERROR and the security status
3245 of the response is also considered secure.
3247 14 February 2014: Wouter
3248 - Works on Minix (3.2.1).
3250 11 February 2014: Wouter

3275 - Fix for hex to string in unknown, atma and nsap.
3276 - fixup nss compile (no ldns in it).
3277 - fixup warning in unitldns
3278 - fixup WKS and rdata type service to print unsigned because strings
3279 are not portable; they cannot be read (for sure) on other computers.
3280 - fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
3283 30 January 2014: Wouter
3284 - delay-close does not act if there are udp-wait queries, so that
3285 it does not make a socketdrain DoS easier.
3287 28 January 2014: Wouter
3288 - iana portlist updated.
3289 - iana portlist test updated so it does not touch the source
3290 if there are no changes.
3291 - delay-close: msec option that delays closing ports for which
3292 the UDP reply has timed out. Keeps the port open, only accepts
3293 the correct reply. This correct reply is not used, but the port
3294 is open so that no port-denied ICMPs are generated.
3296 27 January 2014: Wouter
3297 - reuseport is attempted, then fallback to without on failure.
3299 24 January 2014: Wouter
3300 - Change unbound-event.h to use void* buffer, length idiom.
3301 - iana portlist updated.
3302 - unbound-event.h is installed if you configure --enable-event-api.
3303 - speed up unbound (reports say it could be up to 10%), by reducing
3304 lock contention on localzones.lock. It is changed to an rwlock.
3305 - so-reuseport: yesno option to distribute queries evenly over
3306 threads on Linux (Thanks Robert Edmonds).
3309 21 January 2014: Wouter
3310 - Fix #547: no trustanchor written if filesystem full, fclose checked.
3312 17 January 2014: Wouter
3313 - Fix isprint() portability in sldns, uses unsigned int.
3314 - iana portlist updated.
3316 16 January 2014: Wouter
3317 - fix #544: Fixed +i causes segfault when running with module conf
3319 - Windows port, adjust %lld to %I64d, and warning in win_event.c.
3321 14 January 2014: Wouter
3322 - iana portlist updated.
3325 - Fix bug in cachedump that uses sldns.
3326 - update pythonmod for ldns_ to sldns_ name change.
3329 - Fix sldns to use sldns_ prefix for all ldns_ variables.
3330 - Fix windows compile to compile with sldns.
3333 - Fix sldns to make globals use sldns_ prefix. This fixes
3334 linking with libldns that uses global variables ldns_ .
3337 - Fix bug#537: compile python plugin without ldns library.
3340 - Fix bug#536: acl_deny_non_local and refuse_non_local added.
3343 - Patch from Neel Goyal to fix async id assignment if callback
3344 is called by libunbound in the mesh attach.
3345 - Accept ip-address: as an alternative for interface: for
3346 consistency with nsd.conf syntax.
3349 - Patch from Neel Goyal to fix callback in libunbound.
3352 - if configured --with-libunbound-only fix make install.
3355 - Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
3356 more specific interface port 53 can be used at the same time, and
3357 one of the daemons is unbound.
3358 - iana portlist update.
3359 - separate ldns into core ldns inside ldns/ subdirectory. No more
3360 --with-ldns is needed and unbound does not rely on libldns.
3361 - portability fixes for new USE_SLDNS ldns subdir codebase.
3364 - Patch from Neel Goyal: Add an API call to set an event base on an
3365 existing ub_ctx. This basically just destroys the current worker and
3366 sets the event base to the current. And fix a deadlock in
3367 ub_resolve_event – the cfglock is held when libworker_create is
3368 called. This ends up trying to acquire the lock again in
3369 context_obtain_alloc in the call chain.
3370 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
3373 - unbound-event.h is installed if configured --with-libevent. It
3374 contains low-level library calls, that use libevent's event_base
3375 and an ldns_buffer for the wire return packet to perform async
3376 resolution in the client's eventloop.
3379 - 1.4.21 tag created.
3380 - trunk has 1.4.22 number inside it.
3381 - iana portlist updated.
3382 - acx_nlnetlabs.m4 to 26; improve FLTO help text.
3385 - Fix#524: max-udp-size not effective to non-EDNS0 queries, from
3389 - MIN_TTL and MAX_TTL also in time_t.
3390 - tag 1.4.21rc1 made again.
3393 - More fixes for bug#519: for the threaded case test if the bg
3394 thread has been killed, on ub_ctx_delete, to avoid hangs.
3397 - more fixes that I overlooked.
3398 - review fixes from Willem.
3401 - Fix#520: Errors found by static analysis from Tomas Hozza(redhat).
3404 - Fix for 2038, with time_t instead of uint32_t.
3407 - Fix#519 ub_ctx_delete may hang in some scenarios (libunbound).
3410 - Fix uninit variable in fix#516.
3413 - Fix#516 dnssec lameness detection for answers that are improper.
3419 - Fix#512 memleak in testcode for testbound (if it fails).
3420 - Fix#512 NSS returned arrays out of setup function to be statics.
3423 - max include of 100.000 files (depth and globbed at one time).
3424 This is to preserve system memory in bug cases, or endless cases.

3428 - streamtcp man page, contributed by Tomas Hozza.
3429 - iana portlist updated.
3430 - libunbound documentation on how to avoid openssl race conditions.

3434 not connected, to avoid spamming syslog.
3435 - configure --disable-flto option (from Robert Edmonds).
3438 - Fix for const string literals in C++ for libunbound, from Karel
3440 - iana portlist updated.
3443 - Fixup manpage syntax.
3446 - get_option and set_option support for log-time-ascii, python-script
3447 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
3448 immediately. The others are mostly useful for libunbound users.
3451 - get_option, set_option, unbound-checkconf -o and libunbound
3452 getoption and setoption support cache-min-ttl and cache-max-ttl.
3455 - Fix#501: forward-first does not recurse, when forward name is ".".
3456 - iana portlist update.
3457 - Max include depth is unlimited.
3460 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply
3461 patch to it to not fail when -Werror is also specified, from the
3463 - iana portlist update.
3466 - Explain bogus and secure flags in libunbound more.
3469 - Fix#499 use-after-free in out-of-memory handling code (thanks Jake

4058 27 October 2011: Wouter
4059 - lame-ttl and lame-size options no longer exist, it is integrated
4060 with the host info. They are ignored (with verbose warning) if
4061 encountered to keep the config file backwards compatible.
4062 - fix iana-update for changing gzip compression of results.
4063 - fix export-all-symbols on OSX.
4065 26 October 2011: Wouter
4066 - iana portlist updated.
4067 - Infra cache stores information about ping and lameness per IP, zone.
4068 This fixes bug #416.
4069 - fix iana_update target for gzipped file on iana site.
4071 24 October 2011: Wouter
4072 - Fix resolve of partners.extranet.microsoft.com with a fix for the
4073 server selection for choosing out of a (particular) list of bad
4075 - Fix make_new_space function so that the incoming query is not
4076 overwritten if a jostled out query causes a waiting query to be
4077 resumed that then fails and sends an error message. (Thanks to
4080 21 October 2011: Wouter
4081 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
4082 option enabled because of memory layout exe vs dll.
4084 19 October 2011: Wouter
4085 - fix unbound-anchor for broken strptime on OSX lion, detected
4087 - Detect if GOST really works, openssl1.0 on OSX fails.
4088 - Implement ipv6%interface notation for scope_id usage.
4090 17 October 2011: Wouter
4091 - better documentation for inform_super (Thanks Yang Zhe).
4093 14 October 2011: Wouter
4094 - Fix for out-of-memory condition in libunbound (thanks
4097 13 October 2011: Wouter
4098 - Fix --enable-allsymbols, it depended on link specifics of the
4099 target platform, or fptr_wlist assertion failures could occur.
4101 12 October 2011: Wouter
4102 - updated contrib/unbound_munin_ to family=auto so that it works with
4103 munin-node-configure automatically (if installed as
4104 /usr/local/share/munin/plugins/unbound_munin_ ).
4106 27 September 2011: Wouter
4107 - unbound.exe -w windows option for start and stop service.
4109 23 September 2011: Wouter
4110 - TCP-upstream calculates tcp-ping so server selection works if there
4113 20 September 2011: Wouter
4114 - Fix classification of NS set in answer section, where there is a
4115 parent-child server, and the answer has the AA flag for dir.slb.com.
4116 Thanks to Amanda Constant from Secure64.
4118 16 September 2011: Wouter
4119 - fix bug #408: accept patch from Steve Snyder that comments out
4120 unused functions in lookup3.c.
4121 - iana portlist updated.
4122 - fix EDNS1480 change memleak and TCP fallback.
4123 - fix various compiler warnings (reported by Paul Wouters).
4124 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
4125 fetch if sentcount > 3, stop query if sentcount > 16. Count is
4126 reset when referral or CNAME happens. This makes unbound better
4127 at managing large NS sets, they are explored when there is continued
4128 interest (in the form of queries).
4130 15 September 2011: Wouter
4132 - trunk contains 1.4.14 in development.
4133 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
4135 12 September 2011: Wouter
4136 - Reverted dns EDNS backoff fix, it did not help and needs
4137 fragmentation fixes instead.
4140 7 September 2011: Wouter
4141 - Fix operation in ipv6 only (do-ip4: no) mode.
4143 6 September 2011: Wouter
4144 - fedora specfile updated.
4146 5 September 2011: Wouter
4149 2 September 2011: Wouter
4150 - iana portlist updated.
4152 26 August 2011: Wouter
4153 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
4154 - Fix validation failures due to EDNS backoff retries, the retry
4155 for fetch of data has want_dnssec because the iter_indicate_dnssec
4156 function returns true when validation failure retry happens, and
4157 then the serviced query code does not fallback to noEDNS, even if
4158 the cache says it has this. This helps for DLV deployment when
4159 the DNSSEC status is not known for sure before the lookup concludes.
4161 24 August 2011: Wouter
4162 - Applied patch from Karel Slany that fixes a memory leak in the
4163 unbound python module, in string conversions.
4165 22 August 2011: Wouter
4166 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
4167 Zhang and Luo Ce). Unbound responds with the RR types that are
4168 available at the name for qtype ANY and validates those RR types.
4169 It does not test for completeness (i.e. with NSEC or NSEC3 query),
4170 and it does not follow the CNAME or DNAME to another name (with
4171 even more data for the already large response).
4172 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
4173 - Documented the options that work with control set_option command.
4174 - tcp-upstream yes/no option (works with set_option) for tunnels.
4176 18 August 2011: Wouter
4177 - fix autoconf call in makedist crosscompile to RC or snapshot.
4179 17 August 2011: Wouter

4182 - iana portlist updated.
4184 10 August 2011: Wouter
4185 - Fix python site-packages path to /usr/lib64.
4186 - updated patch from Tom.
4187 - fix memory and fd leak after out-of-memory condition.
4189 9 August 2011: Wouter
4190 - patch from Tom Hendrikx fixes load of python modules.
4192 8 August 2011: Wouter

4195 1 August 2011: Wouter
4196 - Fix autoconf 2.68 warnings
4198 14 July 2011: Wouter
4199 - Unbound implements RFC6303 (since version 1.4.7).
4200 - tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
4201 meantime, those are for 1.4.13).
4202 - iana portlist updated.
4204 13 July 2011: Wouter
4205 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
4207 11 July 2011: Wouter
4208 - Fix wildcard expansion no-data reply under an optout NSEC3 zone is
4209 validated as insecure, reported by Jia Li (lijia@cnnic.cn).
4212 - 1.4.12rc1 tag created.
4215 - version number in example config file.
4216 - fix that --enable-static-exe does not complain about it unknown.
4218 30 June 2011: Wouter
4219 - tag relase 1.4.11, trunk is 1.4.12 development.
4220 - iana portlist updated.
4221 - fix bug#395: id bits of other query may leak out under conditions
4222 - fix replyaddr count wrong after jostled queries, which leads to
4223 eventual starvation where the daemon has no replyaddrs left to use.
4224 - fix comment about rndc port, that referred to the old port number.
4225 - fix that the listening socket is not closed when too many remote
4226 control connections are made at the same time.
4227 - removed ldns-src tarball inside the unbound tarball.
4229 23 June 2011: Wouter
4230 - Changed -flto check to support clang compiler.
4231 - tag 1.4.11rc3 created.
4233 17 June 2011: Wouter
4234 - tag 1.4.11rc1 created.
4235 - remove warning about signed/unsigned from flex (other flex version).
4236 - updated aclocal.m4 and libtool to match.
4237 - tag 1.4.11rc2 created.
4239 16 June 2011: Wouter
4240 - log-queries: yesno option, default is no, prints querylog.
4241 - version is 1.4.11.
4243 14 June 2011: Wouter
4244 - Use -flto compiler flag for link time optimization, if supported.
4245 - iana portlist updated.
4247 12 June 2011: Wouter
4248 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
4250 10 June 2011: Wouter
4251 - unbound-control has version number in the header,
4252 UBCT[version]_space_ is the header sent by the client now.
4253 - Unbound control port number is registered with IANA:
4254 ub-dns-control 8953/tcp unbound dns nameserver control
4255 This is the new default for the control-port config setting.
4256 - statistics-interval prints the number of jostled queries to log.
4259 - Fix Makefile for U in environment, since wrong U is more common than
4260 deansification necessity.
4261 - iana portlist updated.
4262 - updated ldns tarball to 1.6.10rc2 snapshot of today.
4265 - Fix assertion failure when unbound generates an empty error reply
4266 in response to a query, CVE-2011-1922 VU#531342.
4267 - This fix is in tag 1.4.10.
4268 - defense in depth against the above bug, an error is printed to log
4269 instead of an assertion failure.
4272 - bug#386: --enable-allsymbols option links all binaries to libunbound
4273 and reduces install size significantly.
4274 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
4275 - iana portlist updated.
4276 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
4278 14 April 2011: Wouter
4279 - configure created with newer autoconf 2.66.
4281 12 April 2011: Wouter
4282 - bug#378: Fix that configure checks for ldns_get_random presence.
4284 8 April 2011: Wouter
4285 - iana portlist updated.
4286 - queries with CD flag set cause DNSSEC validation, but the answer is
4287 not withheld if it is bogus. Thus, unbound will retry if it is bad
4288 and curb the TTL if it is bad, thus protecting the cache for use by
4289 downstream validators.
4290 - val-override-date: -1 ignores dates entirely, for NTP usage.
4292 29 March 2011: Wouter
4293 - harden-below-nxdomain: changed so that it activates when the
4294 cached nxdomain is dnssec secure. This avoids backwards
4295 incompatibility because those old servers do not have dnssec.
4297 24 March 2011: Wouter
4298 - iana portlist updated.
4302 17 March 2011: Wouter
4303 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
4304 Applied but did not do the --disable-gost.
4306 10 March 2011: Wouter
4307 - tag 1.4.9 release candidate 1 created.
4309 3 March 2011: Wouter
4310 - updated ldns to today.
4312 1 March 2011: Wouter
4313 - Fix no ADflag for NXDOMAIN in NSEC3 optout. And wildcard in optout.
4314 - give config parse error for multiple names on a stub or forward zone.
4315 - updated ldns tarball to 1.6.9(todays snapshot).
4317 24 February 2011: Wouter
4318 - bug #361: Fix, time.elapsed variable not reset with stats_noreset.
4320 23 February 2011: Wouter
4321 - iana portlist updated.
4322 - common.sh to version 3.
4324 18 February 2011: Wouter
4325 - common.sh in testdata updated to version 2.
4327 15 February 2011: Wouter
4328 - Added explicit note on unbound-anchor usage:
4329 Please note usage of unbound-anchor root anchor is at your own risk
4330 and under the terms of our LICENSE (see that file in the source).
4332 11 February 2011: Wouter
4333 - iana portlist updated.
4334 - tpkg updated with common.sh for common functionality.
4336 7 February 2011: Wouter
4337 - Added regression test for addition of a .net DS to the root, and
4338 cache effects with different TTL for glue and DNSKEY.
4339 - iana portlist updated.

4342 - Fix remove private address does not throw away entire response.
4344 24 January 2011: Wouter
4347 19 January 2011: Wouter
4348 - fix bug#349: no -L/usr for ldns.
4350 18 January 2011: Wouter
4351 - ldns 1.6.8 tarball included.
4354 17 January 2011: Wouter
4355 - add get and set option for harden-below-nxdomain feature.
4356 - iana portlist updated.
4358 14 January 2011: Wouter
4359 - Fix so a changed NS RRset does not get moved name stuck on old
4360 server, for type NS the TTL is not increased.
4362 13 January 2011: Wouter
4363 - Fix prefetch so it does not get stuck on old server for moved names.
4365 12 January 2011: Wouter
4366 - iana portlist updated.
4368 11 January 2011: Wouter
4369 - Fix insecure CNAME sequence marked as secure, reported by Bert

4376 - bug#346: remove ITAR scripts from contrib, the service is discontinued, use the root.
4377 - iana portlist updated.
4379 23 December 2010: Wouter
4380 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
4382 21 December 2010: Wouter
4383 - algorithm compromise protection using the algorithms signalled in
4384 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
4385 and thus, if you have multiple algorithms in your trust-anchor-file
4386 then it will now behave different than before. Also, 5011 rollover
4387 for algorithms needs to be double-signature until the old algorithm
4389 It is not an option, because I see no use to turn the security off.
4390 - iana portlist updated.
4392 17 December 2010: Wouter
4393 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
4394 - fix validation in this case: CNAME to nodata for co-hosted opt-in
4395 NSEC3 insecure delegation, was bogus, fixed to be insecure.
4397 16 December 2010: Wouter

4412 - iana portlist updated.
4414 18 November 2010: Wouter
4415 - harden-below-nxdomain option, default off (because very old
4416 software may be incompatible). We could enable it by default in
4419 17 November 2010: Wouter
4420 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
4421 - make test output nicer.
4423 15 November 2010: Wouter
4424 - silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
4425 - iana portlist updated.
4426 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
4428 9 November 2010: Wouter
4429 - unbound-anchor compiles with openssl 0.9.7.
4431 8 November 2010: Wouter
4432 - release tag 1.4.7.

4443 - Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
4445 2 November 2010: Wouter
4449 1 November 2010: Wouter
4450 - GOST code enabled by default (RFC 5933).
4452 27 October 2010: Wouter
4453 - Fix uninit value in dump_infra print.
4454 - Fix validation failure for parent and child on same server with an
4455 insecure childzone and a CNAME from parent to child.
4456 - Configure detects libev-4.00.
4458 26 October 2010: Wouter
4459 - dump_infra and flush_infra commands for unbound-control.
4460 - no timeout backoff if meanwhile a query succeeded.
4461 - Change of timeout code. No more lost and backoff in blockage.
4462 At 12sec timeout (and at least 2x lost before) one probe per IP
4463 is allowed only. At 120sec, the IP is blocked. After 15min, a
4464 120sec entry has a single retry packet.
4466 25 October 2010: Wouter
4467 - Configure errors if ldns is not found.
4469 22 October 2010: Wouter
4470 - Windows 7 fix for the installer.
4472 21 October 2010: Wouter
4473 - Fix bug where fallback_tcp causes wrong roundtrip and edns
4474 observation to be noted in cache. Fix bug where EDNSprobe halted
4475 exponential backoff if EDNS status unknown.
4476 - new unresponsive host method, exponentially increasing block backoff.
4477 - iana portlist updated.
4479 20 October 2010: Wouter
4480 - interface automatic works for some people with ip6 disabled.
4481 Therefore the error check is removed, so they can use the option.
4483 19 October 2010: Wouter
4484 - Fix for request list growth, if a server has long timeout but the
4485 lost counter is low, then its effective rtt is the one without
4486 exponential backoff applied. Because the backoff is not working.
4487 The lost counter can then increase and the server is blacklisted,
4488 or the lost counter does not increase and the server is working
4491 18 October 2010: Wouter
4492 - iana portlist updated.
4494 13 October 2010: Wouter
4495 - Fix TCP so it uses a random outgoing-interface.
4496 - unbound-anchor handles ADDPEND keystate.
4498 11 October 2010: Wouter
4499 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
4500 the zone has a secure delegation hosted on the same server did not
4501 verify as secure (it was insecure by mistake).
4502 - iana portlist updated.
4503 - ldns tarball updated (for reading cachedumps with bad RR data).
4505 1 October 2010: Wouter

4514 - iana portlist updated.
4516 24 September 2010: Wouter

4519 23 September 2010: Wouter
4520 - unbound-anchor app, unbound requires libexpat (xml parser library).

4524 reverse ipv6 orchid prefix from builtin list.
4525 - iana portlist updated.
4527 17 September 2010: Wouter
4528 - DLV has downgrade protection again, because the RFC says so.
4529 - iana portlist updated.
4531 16 September 2010: Wouter
4532 - Algorithm rollover operational reality intrudes, for trust-anchor,

4535 - Fix reported validation error in out of memory condition.
4537 15 September 2010: Wouter

4545 13 September 2010: Wouter
4546 - bug#327: Fix for cannot access stub zones until the root is primed.
4548 9 September 2010: Wouter
4549 - unresponsive servers are not completely blacklisted (because of
4550 firewalls), but also not probed all the time (because of the request
4551 list size it generates). The probe rate is 1%.
4552 - iana portlist updated.
4554 20 August 2010: Wouter
4555 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
4556 iterator get_mem includes priv_get_mem. delegpt nodup removed.
4557 listen_pushback, query_info_allocqname, write_socket, send_packet,
4558 comm_point_set_cb_arg and listen_resume removed.
4560 19 August 2010: Wouter
4561 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
4562 Delegpt structures checked for duplicates always.
4563 No more nameserver lookups generated when depth is full anyway.
4564 - example.conf notes how to do DNSSEC validation and track the root.
4565 - iana portlist updated.
4567 18 August 2010: Wouter
4568 - Fix bug#322: configure does not respect CFLAGS on Solaris.
4569 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
4570 if use sun-cc, but some systems need different flags.
4572 16 August 2010: Wouter
4573 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
4574 changes, uses m4_bpatsubst now.
4575 - make test (or make check) should be more portable and run the unit
4576 test and testbound scripts. (make longtest has special requirements).
4578 13 August 2010: Wouter
4579 - More pleasant remote control command parsing.
4580 - documentation added for return values reported by doxygen 1.7.1.
4581 - iana portlist updated.
4583 9 August 2010: Wouter
4584 - Fix name of rrset printed that failed validation.

4606 - Donation text added to README.
4607 - Fix integer underflow in prefetch ttl creation from cache. This
4608 fixes a potential negative prefetch ttl.
4610 12 July 2010: Wouter
4611 - Changed the defaults for num-queries-per-thread/outgoing-range.
4612 For builtin-select: 512/960, for libevent 1024/4096 and for
4613 windows 24/48 (because of win api). This makes the ratio this way
4614 to improve resilience under heavy load. For high performance, use
4615 libevent and possibly higher numbers.
4617 10 July 2010: Wouter
4618 - GOST enabled if SSL is recent and ldns has GOST enabled too.
4619 - ldns tarball updated.
4622 - iana portlist updated.
4623 - Fix validation of qtype DNSKEY when a key-cache entry exists but
4624 no rr-cache entry is used (it expired or prefetch), it then goes
4625 back up to the DS or trust-anchor to validate the DNSKEY.
4628 - Neat function prototypes, unshadowed local declarations.
4631 - failure to chown the pidfile is not fatal any more.
4632 - testbound uses UTC timezone.
4633 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
4634 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
4637 - log if a server is skipped because it is on the donotquery list,
4638 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
4639 - added feature to print configure date, target and options with -h.
4640 - added feature to print event backend system details with -h.
4641 - wdiff is not actually required by make test, updated requirements.
4644 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
4645 must be signed with all algorithms from the DS rrset at the parent.
4646 This is now checked and becomes bogus if not.
4648 28 June 2010: Wouter
4649 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
4650 in overload situations to be about 5 qps for the class of shortly
4652 The capacity of the resolver is then about (numqueriesperthread / 2)
4653 / (average time for such long queries) qps for long queries.
4654 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
4655 qps for short queries, per thread.
4656 - Fix the max number of reply-address count to be applied for duplicate
4657 queries, and not for new query list entries. This raises the memory
4658 usage to a max of (16+1)*numqueriesperthread reply addresses.
4660 25 June 2010: Wouter
4661 - Fix handling of corner case reply from lame server, follows rfc2308.
4662 It could lead to a nodata reply getting into the cache if the search
4663 for a non-lame server turned up other misconfigured servers.
4664 - unbound.h has extern "C" statement for easier include in c++.
4666 23 June 2010: Wouter
4667 - iana portlist updated.
4668 - makedist upgraded cross compile openssl option, like this:
4669 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
4671 22 June 2010: Wouter
4672 - Unbound reports libev or libevent correctly in logs in verbose mode.
4673 - Fix to unload gost dynamic library module for leak testing.
4675 18 June 2010: Wouter
4676 - iana portlist updated.
4678 17 June 2010: Wouter
4679 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
4681 16 June 2010: Wouter
4682 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
4683 assertion was wrong.
4684 - updated ldns tarball.
4686 15 June 2010: Wouter
4687 - tag 1.4.5 created.
4688 - trunk contains 1.4.6 in development.
4689 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
4690 - Fix to use one pointer less for iterator query state store_parent_NS.
4691 - makedist crosscompile to windows uses builtin ldns not host ldns.
4692 - Max referral count from 30 to 130, because 128 one character domains
4694 - added documentation for the histogram printout to syslog.
4696 11 June 2010: Wouter
4697 - When retry to parent the retrycount is not wiped, so failed
4698 nameservers are not tried again.
4699 - iana portlist updated.
4701 10 June 2010: Wouter
4702 - Fix bug where a long loop could be entered, now cycle detection
4703 has a loop-counter and maximum search amount.
4706 - iana portlist updated.
4707 - 1.4.5rc1 tag created.
4710 - ldns tarball updated, 1.6.5.
4711 - review comments, split dependency cycle tracking for parentside
4712 last resort lookups for A and AAAA so there are more lookup options.
4715 - Fix compile warning if compiled without threads.
4716 - updated ldns-tarball with current ldns svn (pre 1.6.5).
4717 - GOST disabled-by-default, the algorithm number is allocated but the
4718 RFC is still has to pass AUTH48 at the IETF.
4721 - Ignore Z flag in incoming messages too.
4722 - Fix storage of negative parent glue if that last resort fails.
4723 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
4724 - new splint flags for newer splint install.
4727 - Fix AD flag handling, it could in some cases mistakenly copy the AD
4728 flag from upstream servers.
4729 - alloc_special_obtain out of memory is not a fatal error any more,
4730 enabling unbound to continue longer in out of memory conditions.
4731 - parentside names are dispreferred but not said to be dnssec-lame.
4732 - parentside check for cached newname glue.
4733 - fix parentside and querytargets modulestate, for dump_requestlist.
4734 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
4735 - fix parentside from cache to be marked dispreferred for bad names.
4738 - iana portlist updated.
4739 - parent-child disagreement approach altered. Older fixes are
4740 removed in place of a more exhaustive search for misconfigured data
4741 available via the parent of a delegation.
4742 This is designed to be throttled by cache entries, with TTL from the
4743 parent if possible. Additionally the loop-counter is used.
4744 It also tests for NS RRset differences between parent and child.
4745 The fetch of misconfigured data should be more reliable and thorough.
4746 It should work reliably even with no or only partial data in cache.
4747 Data received from the child (as always) is deemed more
4748 authoritative than information received from the delegation parent.
4749 The search for misconfigured data is not performed normally.
4752 - Contribution from Migiel de Vos (Surfnet): nagios patch for
4753 unbound-host, in contrib/ (in the source tarball). Makes
4754 unbound-host suitable for monitoring dnssec(-chain) status.
4757 - EDNS timeout code will not fire if EDNS status already known.
4758 - EDNS failure not stored if EDNS status known to work.
4761 - Fix resolution for domains like safesvc.com.cn. If the iterator
4762 can not recurse further and it finds the delegation in a state
4763 where it would otherwise have rejected it outhand if so received
4764 from a cache lookup, then it can try to ask higherup (with loop
4766 - Fix comments in iter_utils:dp_is_useless.
4769 - Fix various compiler warnings from the clang llvm compiler.
4770 - iana portlist updated.
4773 - Fix bug#308: spelling error in variable name in parser and lexer.
4776 - Fix dnssec-missing detection that was turned off by server selection.
4777 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
4778 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
4779 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
4781 29 April 2010: Wouter
4782 - Fix for dnssec lameness detection to use the key cache.
4783 - infra cache entries that are expired are wiped clean. Previously
4784 it was possible to not expire host data (if accessed often).
4786 28 April 2010: Wouter
4787 - ldns tarball updated and GOST support is detected and then enabled.
4788 - iana portlist updated.
4789 - Fix detection of gost support in ldns (reported by Chris Smith).
4791 27 April 2010: Wouter
4792 - unbound-control get_option domain-insecure shows config file items.
4793 - fix retry sequence if prime hints are recursion-lame.
4794 - autotrust anchor file can be initialized with a ZSK key as well.
4795 - harden-referral-path does not result in failures due to max-depth.
4796 You can increase the max-depth by adding numbers (' 0') after the
4797 target-fetch-policy, this increases the depth to which is checked.
4799 26 April 2010: Wouter
4800 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
4801 CPPFLAGS during configure process.
4802 - if libev is installed on the base system (not libevent), detect
4803 it from the event.h header file and link with -lev.
4804 - configlexer.lex gets config.h, and configyyrename.h added by make,
4805 no more double include.
4806 - More strict scrubber (Thanks to George Barwood for the idea):
4807 NS set must be pertinent to the query (qname subdomain nsname).
4808 - Fix bug#307: In 0x20 backoff fix fallback so the number of
4809 outstanding queries does not become -1 and block the request.
4810 Fixed handling of recursion-lame in combination with 0x20 fallback.
4811 Fix so RRsets are compared canonicalized and sorted if the immediate
4812 comparison fails, this makes it work around round-robin sites.
4814 23 April 2010: Wouter
4815 - Squelch log message: sendto failed permission denied for
4816 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
4817 - Fix to fetch data as last resort more tenaciously. When cycle
4818 targets cause the server selection to believe there are more options
4819 when they really are not there, the server selection is reinitiated.
4820 - Fix fetch from blacklisted dnssec lame servers as last resort. The
4821 server's IP address is then given in validator errors as well.
4822 - Fix local-zone type redirect that did not use the query name for
4825 22 April 2010: Wouter
4827 - trunk contains 1.4.5 in development.
4828 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
4829 The validator error message was 'no signatures from ...'.
4831 16 April 2010: Wouter
4832 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
4835 15 April 2010: Wouter
4836 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
4837 example key and signatures for GOST. GOST requires openssl-1.0.0.
4838 GOST is still disabled by default.
4840 9 April 2010: Wouter
4841 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
4842 get into an endless loop, if 0x20 was enabled, and buffers are small
4843 or particular broken packets are received.
4844 - Fix chain of trust with CNAME at an intermediate step, for the DS
4847 8 April 2010: Wouter
4848 - Fix validation of queries with wildcard names (*.example).
4850 6 April 2010: Wouter
4851 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
4852 cache timeout coincided with a server update, the current EDNS
4853 backoff is less sensitive, and does not cache the backoff unless
4854 the backoff actually works and the domain is not expecting DNSSEC.
4855 - GOST support with correct algorithm numbers.
4857 1 April 2010: Wouter
4858 - iana portlist updated.
4860 24 March 2010: Wouter
4861 - unbound control flushed items are not counted when flushed again.
4863 23 March 2010: Wouter
4864 - iana portlist updated.
4866 22 March 2010: Wouter
4867 - unbound-host disables use-syslog from config file so that the
4868 config file for the main server can be used more easily.
4869 - fix bug#301: unbound-checkconf could not parse interface
4870 '0.0.0.0@5353', even though unbound itself worked fine.
4872 19 March 2010: Wouter
4873 - fix fwd_ancil test to pass if the socket options are not supported.
4875 18 March 2010: Wouter
4876 - Fixed random numbers for port, interface and server selection.
4877 Removed very small bias.
4878 - Refer to the listing in unbound-control man page in the extended
4879 statistics entry in the unbound.conf man page.
4881 16 March 2010: Wouter
4882 - Fix interface-automatic for OpenBSD: msg.controllen was too small,
4883 also assertions on ancillary data buffer.
4884 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
4885 - for NSEC3 check if signatures are cached.
4887 15 March 2010: Wouter
4888 - unit test for util/regional.c.
4890 12 March 2010: Wouter
4891 - Reordered configure checks so fork and -lnsl -lsocket checks are
4892 earlier, and thus later checks benefit from and do not hinder them.
4893 - iana portlist updated.
4894 - ldns tarball updated.
4895 - Fix python use when multithreaded.
4896 - Fix solaris python compile.
4897 - Include less in config.h and include per code file for ldns, ssl.
4899 11 March 2010: Wouter
4900 - another memory allocation option: --enable-alloc-nonregional.
4901 exposes the regional allocations to other memory purifiers.
4902 - fix for memory alignment in struct sock_list allocation.
4903 - Fix for MacPorts ldns without ssl default, unbound checks if ldns
4904 has dnssec functionality and uses the builtin if not.
4905 - Fix daemonize on Solaris 10, it did not detach from terminal.
4906 - tag 1.4.3 created.
4907 - trunk is 1.4.4 in development.
4908 - spelling fix in validation error involving cnames.
4910 10 March 2010: Wouter
4911 - --enable-alloc-lite works with test set.
4912 - portability in the testset: printf format conversions, prototypes.
4914 9 March 2010: Wouter
4915 - tag 1.4.2 created.
4916 - trunk is 1.4.3 in development.
4917 - --enable-alloc-lite debug option.
4919 8 March 2010: Wouter
4920 - iana portlist updated.
4922 4 March 2010: Wouter
4923 - Fix crash in control channel code.
4925 3 March 2010: Wouter
4926 - better casts in pipe code, brackets placed wrongly.
4927 - iana portlist updated.
4929 1 March 2010: Wouter
4930 - make install depends on make all.
4931 - Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
4932 - --enable-checking: enables assertions but does not look nonproduction.
4933 - nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
4934 nxdomain and nodata distinguished.
4935 - ldns tarball updated.
4936 - --disable-rpath fixed for libtool not found errors.
4937 - new fedora specfile from Fedora13 in contrib from Paul Wouters.
4939 26 February 2010: Wouter
4940 - Fixup prototype for lexer cleanup in daemon code.
4941 - unbound-control list_stubs, list_forwards, list_local_zones and
4944 24 February 2010: Wouter
4945 - Fix scrubber bug that potentially let NS records through. Reported
4947 - Also delete potential poison references from additional.
4948 - Fix: no classification of a forwarder as lame, throw away instead.
4950 23 February 2010: Wouter
4951 - libunbound ub_ctx_get_option() added.
4952 - unbound-control set_option and get_option commands.
4953 - iana portlist updated.
4955 18 February 2010: Wouter
4956 - A little more strict DS scrubbing.
4957 - No more blacklisting of unresponsive servers, a 2 minute timeout
4959 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.
4960 - pickup ldns compile fix, libdl for libcrypto.
4961 - log 'tcp connect: connection timed out' only in high verbosity.
4962 - unbound-control log_reopen command.
4963 - moved get_option code from unbound-checkconf to util/config_file.c
4965 17 February 2010: Wouter
4966 - Disregard DNSKEY from authority section for chain of trust.
4967 DS records that are irrelevant to a referral scrubbed. Anti-poison.
4968 - iana portlist updated.
4970 16 February 2010: Wouter
4971 - Check for 'no space left on device' (or other errors) when
4972 writing updated autotrust anchors and print errno to log.
4974 15 February 2010: Wouter
4975 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
4976 hardcoded. We made the choice to send out more conservatively,
4977 protecting against an aggregate effect more than protecting a
4978 single user (from their own folly, perhaps in case of misconfig).
4980 12 February 2010: Wouter
4981 - Re-query pattern changed on validation failure. To protect troubled
4982 authority servers, unbound caches a failure for the DNSKEY or DS
4983 records for the entire zone, and only retries that 900 seconds later.
4984 This implies that only a handful of packets are sent extra to the
4985 authority if the zone fails.
4987 11 February 2010: Wouter
4988 - ldns tarball update for long label length syntax error fix.
4989 - iana portlist updated.
4991 9 February 2010: Wouter
4992 - Fixup in compat snprintf routine, %f 1.02 and %g support.
4993 - include math.h for testbound test compile portability.
4995 2 February 2010: Wouter
4996 - Updated url of IANA itar, interim trust anchor repository, in script.
4998 1 February 2010: Wouter
4999 - iana portlist updated.
5000 - configure test for memcmp portability.
5002 27 January 2010: Wouter
5003 - removed warning on format string in validator error log statement.
5004 - iana portlist updated.
5006 22 January 2010: Wouter
5007 - libtool finish the install of unbound python dynamic library.
5009 21 January 2010: Wouter
5010 - acx_nlnetlabs.m4 synchronised with nsd's version.
5012 20 January 2010: Wouter
5013 - Fixup lookup trouble for parent-child domains on the first query.
5015 14 January 2010: Wouter
5016 - Fixup ldns detection to also check for header files.
5018 13 January 2010: Wouter
5019 - prefetch-key option that performs DNSKEY queries earlier in the
5020 validation process, and that could halve the latency on DNSSEC
5021 queries. It takes some extra processing (CPU, a cache is needed).
5023 12 January 2010: Wouter
5024 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
5026 8 January 2010: Wouter
5027 - Fix for parent-child disagreement code which could have trouble
5028 when (a) ipv6 was disabled and (b) the TTL for parent and child
5029 were different. There were two bugs, the parent-side information
5030 is fixed to no longer block lookup of child side information and
5031 the iterator is fixed to no longer attempt to get ipv6 when it is
5032 not enabled and then give up in failure.
5033 - test and fixes to make prefetch actually store the answer in the
5034 cache. Considers some rrsets 'already expired' but does not allow
5035 overwriting of rrsets considered more secure.
5037 7 January 2010: Wouter
5038 - Fixup python documentation (thanks Leo Vandewoestijne).
5039 - Work on cache prefetch feature.
5040 - Stats for prefetch, in log print stats, unbound-control stats
5041 and in unbound_munin plugin.
5043 6 January 2010: Wouter
5044 - iana portlist updated.
5045 - bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.
5046 - verbose output includes parent-side-address notion for lameness.
5047 - documented val-log-level: 2 setting in example.conf and man page.
5048 - change unbound-control-setup from 1024(sha1) to 1536(sha256).
5050 1 January 2010: Wouter
5051 - iana portlist updated.
5053 22 December 2009: Wouter
5054 - configure with newer libtool 2.2.6b.
5056 17 December 2009: Wouter
5059 - trunk to version 1.4.2.
5061 15 December 2009: Wouter
5062 - Answer to qclass=ANY queries, with class IN contents.
5063 Test that validation also works.
5064 - updated ldns snapshot tarball with latest fixes (parsing records).
5066 11 December 2009: Wouter
5067 - on IPv4 UDP turn off DF flag.
5069 10 December 2009: Wouter
5070 - requirements.txt updated with design choice explanations.
5071 - Reading fixes: fix to set unlame when child confirms parent glue,
5072 and fix to avoid duplicate addresses in delegation point.
5073 - verify_rrsig routine checks expiration last.
5075 9 December 2009: Wouter
5076 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
5077 errors generated for domain names like '.example.com'.
5078 - Fix SOA excluded from negative DS responses. Reported by Hauke
5079 Lampe. The negative cache did not include proper SOA records for
5080 negative qtype DS responses which makes BIND barf on it, such
5081 responses are now only used internally.
5082 - Fix negative cache lookup of closestencloser check of DS type bit.
5084 8 December 2009: Wouter
5085 - Fix for lookup of parent-child disagreement domains, where the
5086 parent-side glue works but it does not provide proper NS, A or AAAA
5087 for itself, fixing domains such as motorcaravanners.eu.
5088 - Feature: you can specify a port number in the interface: line, so
5089 you can bind the same interface multiple times at different ports.
5091 7 December 2009: Wouter
5092 - Bug#287: Fix segfault when unbound-control remove nonexistent local
5093 data. Added check to tests.
5095 1 December 2009: Wouter
5096 - Fix crash with module-config "iterator".
5097 - Added unit test that has "iterator" module-config.
5099 30 November 2009: Wouter
5100 - bug#284: fix parse of # without end-of-line at end-of-file.
5102 26 November 2009: Wouter
5103 - updated ldns with release candidate for version 1.6.3.
5104 - tag for 1.4.0 release.
5105 - 1.4.1 version in trunk.
5106 - Fixup major libtool version to 2 because of why_bogus change.
5107 It was 1:5:0 but should have been 2:0:0.
5109 23 November 2009: Wouter
5110 - Patch from David Hubbard for libunbound manual page.
5111 - Fixup endless spinning in unbound-control stats reported by
5112 Attila Nagy. Probably caused by clock reversal.
5114 20 November 2009: Wouter
5115 - contrib/split-itar.sh contributed by Tom Hendrikx.
5117 19 November 2009: Wouter
5118 - better argument help for unbound-control.
5119 - iana portlist updated.
5121 17 November 2009: Wouter

5123 - iana portlist updated.
5125 16 November 2009: Wouter
5126 - Fixed signer detection of CNAME responses without signatures.
5127 - Fix#282 libunbound memleak on error condition by Eric Sesterhenn.
5128 - Tests for CNAMEs to deeper trust anchors, secure and bogus.
5129 - svn tag 1.4.0rc1 made.
5131 13 November 2009: Wouter
5132 - Fixed validation failure for CNAME to optout NSEC3 nodata answer.
5133 - unbound-host does not fail on type ANY.
5134 - Fixed wireparse failure to put RRSIGs together with data in some
5135 long ANY mix cases, which fixes validation failures.
5137 12 November 2009: Wouter
5138 - iana portlist updated.
5139 - fix manpage errors reported by debian lintian.
5141 - fixup very long vallog2 level error strings.
5143 11 November 2009: Wouter
5144 - ldns tarball updated (to 1.6.2).
5147 10 November 2009: Wouter
5148 - Thanks to Surfnet found bug in new dnssec-retry code that failed
5149 to combine well when combined with DLV and a particular failure.
5150 - Fixed unbound-control -h output about argument optionality.
5153 5 November 2009: Wouter
5154 - lint fixes and portability tests.
5155 - better error text for multiple domain keys in one autotrust file.
5157 2 November 2009: Wouter
5158 - Fix bug where autotrust does not work when started with a DS.
5159 - Updated GOST unit tests for unofficial algorithm number 249
5160 and DNSKEY-format changes in draft version -01.

5168 - removed abort on prealloc failure, error still printed but softfail.
5169 - iana portlist updated.
5170 - RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
5171 - ldns tarball updated (which also enables rsasha256 support).
5173 27 October 2009: Wouter
5174 - iana portlist updated.
5176 8 October 2009: Wouter
5178 - add val-log-level print to corner case (nameserver.epost.bg).
5179 - more detail to errors from insecure delegation checks.
5180 - Fix double time subtraction in negative cache reported by
5181 Amanda Constant and Hugh Mahon.
5182 - Made new validator error string available from libunbound for
5183 applications. It is in result->why_bogus, a zero-terminated string.
5184 unbound-host prints it by default if a result is bogus.
5185 Also the errinf is public in module_qstate (for other modules).
5187 7 October 2009: Wouter
5188 - retry for validation failure in DS and prime results. Less mem use.
5189 unit test. Provisioning in other tests for requeries.

5196 - moved version number to 1.4.0 because of 1.3.4 release with only
5197 the NSEC3 patch from the entry above.
5198 - val-log-level: 2 shows extended error information for validation
5199 failures, but still one (longish) line per failure. For example:
5200 validation failure <example.com. DNSKEY IN>: signature expired from
5201 192.0.2.4 for trust anchor example.com. while building chain of trust
5202 validation failure <www.example.com. A IN>: no signatures from
5203 192.0.2.6 for key example.com. while building chain of trust
5205 6 October 2009: Wouter
5206 - Test set updated to provide additional ns lookup result.
5207 The retry would attempt to fetch the data from other nameservers
5208 for bogus data, and this needed to be provisioned in the tests.

5211 - first validation failure retry code. Retries for data failures.
5214 2 October 2009: Wouter

5223 - review fixes to comments, removed unused code.
5225 25 September 2009: Wouter
5226 - so-rcvbuf: 4m option added. Set this on large busy servers to not
5227 drop the occasional packet in spikes due to full socket buffers.
5228 netstat -su keeps a counter of UDP dropped due to full buffers.
5229 - review of validator/autotrust.c, small fixes and comments.
5231 23 September 2009: Wouter
5232 - 5011 query failed counts verification failures, not lookup failures.
5233 - 5011 probe failure handling fixup.
5234 - test unbound reading of original autotrust data.
5235 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
5236 picked up, otherwise performs initial probe like usual.
5238 22 September 2009: Wouter
5239 - autotrust test with algorithm rollover, new ordering of checks
5240 assists in orderly rollover.
5241 - autotrust test with algorithm rollover to unknown algorithm.
5242 checks if new keys are supported before adding them.
5243 - autotrust test with trust point revocation, becomes unsigned.
5244 - fix DNSSEC-missing-signature detection for minimal responses
5245 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
5247 18 September 2009: Wouter
5248 - autotrust tests, fix trustpoint timer deletion code.
5249 fix count of valid anchors during missing remove.

5264 10 September 2009: Wouter
5265 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
5266 - use linebuffering for log-file: output, this can be significantly
5267 faster than the previous fflush method and enable some class of
5268 resolvers to use high verbosity (for short periods).
5269 Not on windows, because line buffering does not work there.
5271 9 September 2009: Wouter
5272 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
5273 The RRsets would still expire at the normal time, but this would
5274 keep messages bogus in the cache for too long.
5275 - regression test for that bug.
5276 - documented that load_cache is meant for debugging.
5278 8 September 2009: Wouter
5279 - fixup printing errors when load_cache, they were printed to the
5280 SSL connection which broke, now to the log.
5281 - new ldns - with fixed parse of large SOA values.
5283 7 September 2009: Wouter
5284 - autotrust testbound scenarios.
5285 - autotrust fix that failure count is written to file.
5286 - autotrust fix that keys may become valid after add holddown time
5287 alone, before the probe returns.

5290 - Changes to make unbound work with libevent-2.0.3 alpha. (in
5291 configure detection due to new ssl dependency in libevent)
5292 - do not call sphinx for documentation when python is disabled.
5293 - remove EV_PERSIST from libevent timeout code to make the code
5294 compatible with the libevent-2.0. Works with older libevent too.

5361 - autotrust work, split up DS verification of DNSKEYs.
5363 14 August 2009: Wouter
5364 - unbound-control lookup prints out infra cache information, like RTT.
5365 - Fix bug in DLV lookup reported by Amanda from Secure64.
5366 It could sometimes wrongly classify a domain as unsigned, which
5367 does not give the AD bit on replies.
5369 13 August 2009: Wouter
5370 - autotrust read anchor files. locked trust anchors.
5372 12 August 2009: Wouter

5466 29 June 2009: Wouter
5467 - ldns trunk r2959 imported as tarball, because of solaris cc compile
5468 support for c99. r2960 for better configure.
5469 - better wrongly_truncated check.
5470 - On Linux, fragment IPv6 datagrams to the IPv6 minimum MTU, to
5471 avoid dropped packets at routers.
5473 26 June 2009: Wouter
5474 - Fix EDNS fallback when EDNS works for short answers but long answers
5477 22 June 2009: Wouter

5487 - harden-referral-path: handle cases where NS is in answer section.
5489 18 June 2009: Wouter
5490 - Fix of message parse bug where (specifically) an NSEC and RRSIG
5491 in the wrong order would be parsed, but put wrongly into internal
5492 structures so that later validation would fail.
5493 - Extreme lenience for wrongly truncated replies where a positive
5494 reply has an NS in the authority but no signatures. They are
5495 turned into minimal responses with only the (secure) answer.
5496 - autoconf 2.63 for configure.
5497 - python warnings suppress. Keep python API away from header files.
5499 17 June 2009: Wouter
5500 - CREDITS entry for cz.nic, sponsoring a 'summer of code' that was

5504 - Fixup opportunistic target query generation to it does not
5505 generate queries that are known to fail.
5506 - Touchup on munin total memory report.
5507 - messages picked out of the cache by the iterator are checked
5508 if their cname chain is still correct and if validation status
5509 has to be reexamined.
5511 15 June 2009: Wouter
5512 - iana portlist updated.
5514 14 June 2009: Wouter
5515 - Fixed bug where cached responses would lose their security
5516 status on second validation, which especially impacted dlv
5517 lookups. Reported by Hauke Lampe.
5519 13 June 2009: Wouter
5520 - bug #254. removed random whitespace from example.conf.
5522 12 June 2009: Wouter
5523 - Fixup potential wrong NSEC picked out of the cache.
5524 - If unfulfilled callbacks are deleted they are called with an error.
5525 - fptr wlist checks for mesh callbacks.
5526 - fwd above stub in configuration works.
5528 11 June 2009: Wouter
5529 - Fix queries for type DS when forward or stub zones are there.
5530 They are performed to higherup domains, and thus treated as if
5531 going to higher zones when looking up the right forward or stub
5532 server. This makes a stub pointing to a local server that has
5533 a local view of example.com signed with the same keys as are
5534 publicly used work. Reported by Johan Ihren.
5535 - Added build-unbound-localzone-from-hosts.pl to contrib, from
5536 Dennis DeDonatis. It converts /etc/hosts into config statements.
5537 - same thing fixed for forward-zone and DS, chain of trust from
5538 public internet into the forward-zone works now. Added unit test.
5541 - openssl key files are opened apache-style, when user is root and
5542 before chrooting. This makes permissions on remote-control key
5543 files easier to set up. Fixes bug #251.
5544 - flush_type and flush_name remove msg cache entries.
5545 - codereview - dp copy bogus setting fix.
5548 - Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
5549 inadvertant behaviour.
5550 - 1.3.0 tarball for release created.
5551 - 1.3.1 development in svn trunk.
5552 - iana portlist updated.
5553 - fix lint from complaining on ldns/sha.h.
5554 - help compiler figure out aliasing in priv_rrset_bad() routine.
5555 - fail to configure with python if swig is not found.
5556 - unbound_munin_ in contrib uses ps to show rss if sbrk does not work.
5559 - fixup bad free() when wrongly encoded DSA signature is seen.
5560 Reported by Paul Wouters.
5561 - review comments from Matthijs.
5564 - --enable-sha2 option. The draft rsasha256 changed its algorithm
5565 numbers too often. Therefore it is more prudent to disable the
5566 RSASHA256 and RSASHA512 support by default.
5567 - ldns trunk included as new tarball.
5568 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.
5571 - fixup doc bug in README reported by Matthew Dempsky.
5574 - update iana port list
5575 - update ldns lib tarball
5578 - detect lack of IPv6 support on XP (with a different error code).
5579 - Fixup a crash-on-exit which was triggered by a very long queue.
5580 Unbound would try to re-use ports that came free, but this is
5581 of course not really possible because everything is deleted.
5582 Most easily triggered on XP (not Vista), maybe because of the
5583 network stack encouraging large messages backlogs.
5584 - change in debug statements.
5585 - Fixed bug that could cause a crash if root prime failed when there
5586 were message backlogs.
5589 - Thanks again to Brett Carr, found an assertion that was not true.
5590 Assertion checked if recursion parent query still existed.
5592 29 April 2009: Wouter
5593 - Thanks to Brett Carr, caught windows resource leak, use
5594 closesocket() and not close() on sockets or else the network stack
5595 starts to leak handles.
5596 - Removed usage of windows Mutex because windows cannot handle enough
5597 mutexes open. Provide own mutex implementation using primitives.

5623 - fix rsasha512 unit test for new (interim) algorithm number.
5624 - fix test:ldns doesn't like DOS line endings in keyfiles on unix.
5625 - fix compile warning on ubuntu (configlexer fwrite return value).
5626 - move python include directives into CPPFLAGS instead of CFLAGS.
5628 16 April 2009: Wouter
5629 - winsock event handler exit very quickly on signal, even if
5631 - iana portlist updated.

5642 - ldns tarball updated.
5643 - iana portlist update.
5644 - detect GOST support in openssl-1.0.0-beta1, and fix compile problem
5645 because that openssl defines the name STRING for itself.
5647 6 April 2009: Wouter
5648 - windows compile fix.
5649 - Detect FreeBSD jail without ipv6 addresses assigned.
5650 - python libunbound wrapper unit test.

5654 from configure --with-pyunbound:
5655 /usr/lib/python2.x/site-packages/unbound.py
5656 /usr/lib/python2.x/site-packages/_unbound.so*
5657 The example python scripts (pythonmod/examples and
5658 libunbound/python/examples) are not installed.
5659 - python invalidate routine respects packed rrset ids and locks.
5660 - clock skew checks in unbound, config statements.
5661 - nxdomain ttl considerations in requirements.txt
5663 3 April 2009: Wouter
5664 - Fixed a bug that caused messages to be stored in the cache too
5665 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
5666 targets have been more vulnerable to the TTL miscalculation bug.
5667 - documentation test fixed for python addition.
5669 2 April 2009: Wouter
5670 - pyunbound (libunbound python plugin) compiles using libtool.
5671 - documentation for pythonmod and pyunbound is generated in doc/html.
5672 - iana portlist updated.

5737 - Added tests, unknown algorithms become insecure. fallback works.
5738 - Fix for and test for unknown algorithms in a trust anchor
5739 definition. Trust anchors with no supported algos are ignored.
5740 This means a (higher)DS or DLV entry for them could succeed, and
5741 otherwise they are treated as insecure.
5742 - domain-insecure: "example.com" statement added. Sets domain
5743 insecure regardless of chain of trust DSs or DLVs. The inverse
5746 17 March 2009: Wouter

5772 - install and service with log to file works on XP and Vista on
5773 default install location.
5774 - on windows logging to the Application logbook works (as a service).
5775 - fix RUN_DIR on windows compile setting in makedist.
5776 - windows registry has Software\Unbound\ConfigFile element.

5828 update-anchor.sh, and updates from the IANA ITAR repository.
5829 You can provide your own PGP key and trust repo, or can use the
5830 builtin. The program uses wget and gpg to work.
5831 - iana portlist updated.
5832 - update-itar.sh: using ftp:// urls because https godaddy certificate
5833 is not available everywhere and then gives fatal errors. The
5834 security is provided by pgp signature.
5836 18 February 2009: Wouter
5837 - more cycle detection. Also for target queries.
5838 - fixup bug where during deletion of the mesh queries the callbacks

5841 on quit and flush_requestlist.
5842 - iana portlist updated.
5844 13 February 2009: Wouter

5876 - verbosity level 5 logs customer IP for new requestlist entries.
5877 - test fix, lexer and cancel test.

5879 in the log file as Feb 06 13:45:26 (like syslog does).
5880 - detect event_base_new in libevent-1.4.1 and later and use it.
5881 - #231 unbound-checkconf -o option prints that value from config file.
5882 Useful for scripting in management scripts and the like.
5884 5 February 2009: Wouter
5885 - ldns 1.5.0 rc as tarball included.
5886 - 1.3.0 development continues:
5887 change in libunbound API: ub_cancel can return an error, that
5888 the async_id did not exist, or that it was already delivered.
5889 The result could have been delivered just before the cancel
5890 routine managed to acquire the lock, so a caller may get the
5891 result at the same time they call cancel. For this case,
5892 ub_cancel tries to return an error code.
5893 Fixes race condition in ub_cancel() libunbound function.
5894 - MacOSX Leopard cleaner text output from configure.
5895 - initgroups(3) is called to drop secondary group permissions, if
5897 - configure option --with-ldns-builtin forces the use of the
5898 inluded ldns package with the unbound source. The -I include
5899 is put before the others, so it avoids bad include files from
5900 an older ldns install.
5901 - daemon(3) posix call is used when available.
5902 - testbound test for older fix added.
5904 4 February 2009: Wouter

5913 16 January 2009: Wouter
5914 - more quiet about ipv6 network failures, i.e. when ipv6 is not
5915 available (network unreachable). Debug still printed on high
5917 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
5918 debugging with unbound-host -4 -d ...
5919 - more cycle detection for NS-check, addr-check, root-prime and
5920 stub-prime queries in the iterator. Avoids possible deadlock
5923 15 January 2009: Wouter
5924 - bug #229: fixup configure checks for compilation with Solaris
5925 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc
5926 - fixup suncc warnings.
5927 - fix bug where unbound could crash using libevent 1.3 and older.
5928 - update testset for recent retry change.
5930 14 January 2009: Wouter
5931 - 1.2.1 feature: negative caching for failed queries.
5932 Queries that failed are cached for 5 seconds (NORR_TTL).
5933 If the failure is local, like out of memory, it is not cached.
5934 - the TTL comparison for the cache used different comparisons,
5935 causing many cache responses that used the iterator and validator
5936 state machines unnecessarily.
5937 - retry from 4 to 5 so that EDNS drop retry is part of the first
5938 query resolve attempt, and cached error does not stop EDNS fallback.
5939 - remove debug prints that protect against bad referrals.
5940 - honor QUIET=no on make commandline (or QUIET=yes ).
5942 13 January 2009: Wouter

5964 - remove possible race condition in the test for race conditions.
5966 7 January 2009: Wouter
5967 - version 1.2.0 in preparation.
5968 - feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
5969 statements. (Adapted from patch by Paul Wouters).
5970 - typo fix and iana portlist updated.
5971 - porting testsuite; unused var warning, and type fixup.
5973 6 January 2009: Wouter
5974 - fixup packet-of-death when compiled with --enable-debug.
5975 A malformed packet could cause an internal assertion failure.
5976 - added test for HINFO canonicalisation behaviour.
5977 - fixup reported problem with transparent local-zone data where
5978 queries with different type could get nxdomain. Now queries
5979 with a different name get resolved normally, with different type
5980 get a correct NOERROR/NODATA answer.
5981 - HINFO no longer downcased for validation, making unbound compatible
5983 - fix reading included config files when chrooted.
5984 Give full path names for include files.
5985 Relative path names work if the start dir equals the working dir.
5986 - fix libunbound message transport when no packet buffer is available.
5988 5 January 2009: Wouter
5989 - fixup getaddrinfo failure handling for remote control port.
5990 - added L.ROOT-SERVERS.NET. AAAA 2001:500:3::42 to builtin root hints.
5991 - fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
5992 - comm_timer_set performs base_set operation after event_add.
5994 18 December 2008: Wouter
5995 - fixed bug reported by Duane Wessels: error in DLV lookup, would make
5996 some zones that had correct DLV keys as insecure.
5997 - follows -rc makedist from ldns changes (no _rc).
5998 - ldns tarball updated with 1.4.1rc for DLV unit test.
5999 - verbose prints about recursion lame detection and server selection.
6000 - fixup BSD port for infra host storage. It hashed wrongly.
6001 - fixup makedist snapshot name generation.
6002 - do not reopen syslog to avoid dev/log dependency.

6008 contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
6010 16 December 2008: Wouter
6011 - follow makedist improvements from ldns, for maintainers prereleases.
6012 - snapshot version uses _ not - to help rpm distinguish the
6015 11 December 2008: Wouter
6016 - better fix for bug #219: use LOG_NDELAY with openlog() call.
6017 Thanks to Tamas Tevesz.
6019 9 December 2008: Wouter
6020 - bug #221 fixed: unbound checkconf checks if key files exist if
6021 remote control is enabled. Also fixed NULL printf when not chrooted.
6022 - iana portlist updated.
6024 3 December 2008: Wouter
6025 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
6026 freezes up unbound if this was compiled without threading, and
6027 was using multiple processes.
6028 - iana portlist updated.
6029 - test for remote control with interprocess communication.
6030 - created command distribution mechanism so that remote control
6031 commands other than 'stats' work on all processes in a nonthreaded
6032 compiled version. dump/load cache work, on the first process.
6033 - fixup remote control local_data addition memory corruption bug.
6035 1 December 2008: Wouter
6036 - SElinux policy files in contrib/selinux for the unbound daemon,
6037 by Paul Wouters and Adam Tkac.

6041 - skip unsupported feature tests on vista/mingw.
6042 - fixup testcode/streamtcp to work on vista/mingw.
6043 - root-hints test checks version of dig required.
6044 - blacklisted servers are polled at a low rate (1%) to see if they
6045 come back up. But not if there is some other working server.
6047 24 November 2008: Wouter
6048 - document that the user of the server daemon needs read privileges
6049 on the keys and certificates generated by unbound-control-setup.
6050 This is different per system or distribution, usually, running the
6051 script under the same username as the server uses suffices.
6052 i.e. sudo -u unbound unbound-control-setup
6053 - testset port to vista/mingw.
6054 - tcp_sigpipe to freebsd port.
6056 21 November 2008: Wouter
6057 - fixed tcp accept, errors were printed when they should not.
6058 - unbound-control-setup.sh removes read/write permissions other
6059 from the keys it creates (as suggested by Dmitriy Demidov).
6061 20 November 2008: Wouter
6062 - fixup fatal error due to faulty error checking after tcp accept.
6063 - add check in rlimit to avoid integer underflow.
6064 - rlimit check with new formula; better estimate for number interfaces
6065 - nicer comments in rlimit check.
6066 - tag 1.1.1 created in svn.
6067 - trunk label is 1.1.2
6069 19 November 2008: Wouter

6080 17 November 2008: Wouter
6081 - theoretical fix for problems reported on mailing list.
6082 If a delegation point has no A but only AAAA and do-ip6 is no,
6083 resolution would fail. Fixed to ask for the A and AAAA records.
6084 It has to ask for both always, so that it can fail quietly, from
6085 TLD perspective, when a zone is only reachable on one transport.
6086 - test for above, only AAAA and doip6 is no. Fix causes A record
6087 for nameserver to be fetched.
6088 - fixup address duplication on cache fillup for delegation points.
6089 - testset updated for new query answer requirements.

6104 12 November 2008: Wouter
6105 - add unbound-control manpage to makedist replace list.
6107 11 November 2008: Wouter
6108 - unit test for negative cache, stress tests the refcounting.
6109 - fix for refcounting error that could cause fptr_wlist fatal exit
6110 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
6111 Attila Nagy for testing).
6112 - nicer comments in cachedump about failed RR to string conversion.

6133 - if query and reply qname overlap, the bytes are skipped not copied.
6134 - fixed file descriptor leak when messages were jostled out that
6135 had outstanding (TCP) replies.
6136 - DNAMEs used from cache have their synthesized CNAMEs initialized
6138 - fixed file descriptor leak for localzone type deny (for TCP).
6139 - fixed memleak at exit for nsec3 negative cached zones.
6140 - fixed memleak for the keyword 'nodefault' when reading config.
6141 - made verbosity of 'edns incapable peer' warning higher, so you
6142 do not get spammed by it.
6143 - caught elusive Bad file descriptor error bug, that would print the
6144 error while unnecessarily try to listen to a closed fd. Fixed.
6146 4 November 2008: Wouter
6147 - fixed -Wwrite-strings warnings that result in better code.
6149 3 November 2008: Wouter

6162 22 October 2008: Wouter
6163 - CFLAGS are picked up by configure from the environment.
6164 - iana portlist updated.
6165 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
6166 - new stub-prime: yesno option. Default is off, so it does not prime.
6167 can be turned on to get same behaviour as previous unbound release.
6168 - made automated test that checks if builtin root hints are uptodate.
6169 - finished draft-wijngaards-dnsext-resolver-side-mitigation
6170 implementation. The unwanted-reply-threshold can be set.
6171 - fixup so fptr_whitelist test in alloc.c works.
6173 21 October 2008: Wouter
6174 - fix update-anchors.sh, so it does not report different RR order
6175 as an update. Sorts the keys in the file. Updated copyright.
6176 - fixup testbound on windows, the command control pipe doesn't exist.
6177 - skip 08hostlib test on windows, no fork() available.
6178 - made unbound-remote work on windows.
6180 20 October 2008: Wouter
6181 - quench a log message that is debug only.
6182 - iana portlist updated.
6183 - do not query bogus nameservers. It is like nameservers that have
6184 the NS or A or AAAA record bogus are listed as donotquery.
6185 - if server selection is faced with only bad choices, it will
6186 attempt to get more options to be fetched.
6187 - changed bogus-ttl default value from 900 to 60 seconds.
6188 In anticipation that operator caused failures are more likely than
6189 actual attacks at this time. And thus repeated validation helps
6190 the operators get the problem fixed sooner. It makes validation
6191 failures go away sooner (60 seconds after the zone is fixed).
6192 Also it is likely to try different nameserver targets every minute,
6193 so that if a zone is bad on one server but not another, it is
6194 likely to pick up the 'correct' one after a couple minutes,
6195 and if the TTL is big enough that solves validation for the zone.
6196 - fixup unbound-control compilation on windows.
6198 17 October 2008: Wouter
6199 - port Leopard/G5: fixup type conversion size_t/uint32.

6203 and attemps to validate the entries.
6205 16 October 2008: Wouter
6206 - Fixup negative TTL values appearing (reported by Attila Nagy).
6208 15 October 2008: Wouter

6211 as well as very careful NS caching (only when doing NS query).
6212 A, AAAA use the delegation from the NS-query.
6214 14 October 2008: Wouter
6215 - fwd_three.tpkg test was flaky. If the three requests hit the
6216 wrong threads by chance (or bad OS) then the test would fail.
6217 Made less flaky by increasing number of retries.
6218 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
6219 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
6220 Which includes the ldns_dname_absolute fix.
6221 - fwd_three test remains flaky now that unbound does not stop
6222 listening when full. Thus, removed timeout problem.
6223 It may be serviced by three threads, or maybe by one.
6224 Mostly only useful for lock-check testing now.
6226 13 October 2008: Wouter
6227 - fixed recursion servers deployed as authoritative detection, so
6228 that as a last resort, a +RD query is sent there to get the
6230 - iana port list update.

6256 can restart unbound exactly when needed.
6258 30 September 2008: Wouter
6259 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
6260 - tests for sha256 support and downgrade resistance.

6262 using the drafted protocol numbers.
6263 - when using stub on localhost (127.0.0.1@10053) unbound works.
6264 Like when running NSD to host a local zone, on the same machine.
6265 The noprime feature. manpages more explanation. Added a test for it.
6266 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
6268 29 September 2008: Wouter
6269 - EDNS lameness detection, if EDNS packets are dropped this is

6706 It will detect and convert when necessary.
6708 14 April 2008: Wouter
6709 - got update for parseunbound.pl statistics script from Kai Storbeck.
6710 - tpkg tests for udp wait list.
6711 - documented 0x20 status.
6712 - fixup chroot and checkconf, it is much smarter now.
6713 - fixup DSA EVP signature decoding. Solution that Jelte found copied.
6714 - and check first sig byte for the encoding type.
6716 11 April 2008: Wouter
6717 - random port selection out of the configged ports.
6718 - fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
6719 - removed base_port.
6720 - created 256-port ephemeral space for the OS, 59802 available.
6721 - fixup consistency of port_if out array during heavy use.
6723 10 April 2008: Wouter
6724 - --with-libevent works with latest libevent 1.4.99-trunk.
6725 - added log file statistics perl script to contrib.
6726 - automatic iana ports update from makefile. 60058 available.
6728 9 April 2008: Wouter
6729 - configure can detect libev(from its build directory) when passed
6730 --with-libevent=/home/wouter/libev-3.2
6731 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
6732 - unused commpoints not listed in epoll list.
6733 - statistics-cumulative option so that the values are not reset.
6734 - config creates array of available ports, 61841 available,
6735 it excludes <1024 and iana assigned numbers.
6736 config statements to modify the available port numbers.
6738 8 April 2008: Wouter
6739 - unbound tries to set the ulimit fds when started as server.
6740 if that does not work, it will scale back its requirements.
6742 27 March 2008: Wouter
6743 - documented /dev/random symlink from chrootdir as FAQ entry.
6745 26 March 2008: Wouter
6746 - implemented AD bit signaling. If a query sets AD bit (but not DO)
6747 then the AD bit is set in the reply if the answer validated.
6748 Without including DNSSEC signatures. Useful if you have a trusted
6749 path from the client to the resolver. Follows dnssec-updates draft.
6751 25 March 2008: Wouter
6752 - implemented check that for NXDOMAIN and NOERROR answers a query
6753 section must be present in the reply (by the scrubber). And it must
6754 be equal to the question sent, at least lowercase folded.
6755 Previously this feature happened because the cache code refused
6756 to store such messages. However blocking by the scrubber makes
6757 sure nothing gets into the RRset cache. Also, this looks like a
6758 timeout (instead of an allocation failure) and this retries are
6759 done (which is useful in a spoofing situation).
6760 - RTT banding. Band size 400 msec, this makes band around zero (fast)
6761 include unknown servers. This makes unbound explore unknown servers.
6763 7 March 2008: Wouter
6764 - -C config feature for harvest program.
6765 - harvest handles CNAMEs too.
6767 5 March 2008: Wouter
6768 - patch from Hugo Koji Kobayashi for iterator logs spelling.
6770 4 March 2008: Wouter
6771 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
6772 of a cname trust chain is lower; not full answer_AA.
6773 - test for this fix.
6774 - default config file location is /usr/local/etc/unbound.
6775 Thus prefix is used to determine the location. This is also the
6776 chroot and pidfile default location.
6778 3 March 2008: Wouter
6779 - Create 0.10 svn tag.
6780 - 0.11 version in trunk.
6781 - indentation nicer.
6783 29 February 2008: Wouter
6784 - documentation update.
6785 - fixup port to Solaris of perf test tool.
6786 - updated ldns-tarball with decl-after-statement fixes.
6788 28 February 2008: Wouter
6789 - fixed memory leaks in libunbound (during cancellation and wait).
6790 - libunbound returns the answer packet in full.
6791 - snprintf compat update.
6792 - harvest performs lookup.
6793 - ldns-tarball update with fix for ldns_dname_label.
6794 - installs to sbin by default.
6795 - install all manual pages (unbound-host and libunbound too).
6797 27 February 2008: Wouter
6798 - option to use caps for id randomness.
6799 - config file option use-caps-for-id: yes
6800 - harvest debug tool
6802 26 February 2008: Wouter
6803 - delay utility delays TCP as well. If the server that is forwarded
6804 to has a TCP error, the delay utility closes the connection.
6805 - delay does REUSE_ADDR, and can handle a server that closes its end.
6806 - answers use casing from query.
6808 25 February 2008: Wouter
6809 - delay utility works. Gets decent thoughput too (>20000).
6811 22 February 2008: Wouter
6812 - +2% for recursions, if identical queries (except for destination
6813 and query ID) in the reply list, avoid re-encoding the answer.
6814 - removed TODO items for optimizations that do not show up in
6816 - default is now minievent - not libevent. As its faster and
6817 not needed for regular installs, only for very large port ranges.
6818 - loop check different speedup pkt-dname-reading, 1% faster for
6819 nocache-recursion check.
6820 - less hashing during msg parse, 4% for recursion.
6821 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
6822 - some speed results noted:
6823 optimization resulted in +40% for recursion (cache miss) and
6824 +70 to +80 for cache hits, and +96% for version.bind.
6825 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
6826 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
6827 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
6828 So, unbound can be about equal qps to NSD in cache hits.
6829 And about 3.4x faster than BIND in cache performance.
6830 - delay utility for testing.
6832 21 February 2008: Wouter
6833 - speedup of root-delegation message encoding by 15%.
6834 - minor speedup of compress tree_lookup, maybe 1%.
6835 - speedup of dname_lab_cmp and memlowercmp - the top functions in
6836 profiler output, maybe a couple percent when it matters.
6838 20 February 2008: Wouter
6839 - setup speec_cache for need-ldns-testns in dotests.
6840 - check number of queued replies on incoming queries to avoid overload
6842 - fptr whitelist checks are not disabled in optimize mode.
6843 - do-daemonize config file option.
6844 - minievent time share initializes time at start.
6845 - updated testdata for nsec3 new algorithm numbers (6, 7).
6846 - small performance test of packet encoding (root delegation).
6848 19 February 2008: Wouter
6849 - applied patch to unbound-host man page from Jan-Piet Mens.
6850 - fix donotquery-localhost: yes default (it erroneously was switched
6852 - time is only gotten once and the value is shared across unbound.
6853 - unittest cleans up crypto, so that it has no memory leaks.
6854 - mini_event shares the time value with unbound this results in
6855 +3% speed for cache responses and +9% for recursions.
6856 - ldns tarball update with new NSEC3 sign code numbers.
6857 - perform several reads per UDP operation. This improves performance
6858 in DoS conditions, and costs very little in normal conditions.
6859 improves cache response +50%, and recursions +10%.
6860 - modified asynclook test. because the callback from async is not
6861 in any sort of lock (and thus can use all library functions freely),
6862 this causes a tiny race condition window when the last lock is
6863 released for a callback and a new cancel() for that callback.
6864 The only way to remove this is by putting callbacks into some
6865 lock window. I'd rather have the small possibility of a callback
6866 for a cancelled function then no use of library functions in
6867 callbacks. Could be possible to only outlaw process(), wait(),
6868 cancel() from callbacks, by adding another lock, but I'd rather not.
6870 18 February 2008: Wouter
6871 - patch to unbound-host from Jan-Piet Mens.
6872 - unbound host prints errors if fails to configure context.
6873 - fixup perf to resend faster, so that long waiting requests do
6874 not hold up the queue, they become lost packets or SERVFAILs,
6875 or can be sent a little while later (i.e. processing time may
6876 take long, but throughput has to be high).
6877 - fixup iterator operating in no cache conditions (RD flag unset
6879 - streamlined code for RD flag setting.
6880 - profiled code and changed dname compares to be faster.
6881 The speedup is about +3% to +8% (depending on the test).
6882 - minievent tests for eintr and eagain.
6884 15 February 2008: Wouter
6885 - added FreeBSD rc.d script to contrib.
6886 - --prefix option for configure also changes directory: pidfile:
6887 and chroot: defaults in config file.
6888 - added cache speed test, for cache size OK and cache too small.
6890 14 February 2008: Wouter
6891 - start without a config file (will complain, but start with
6893 - perf test program works.
6895 13 February 2008: Wouter
6897 - 1.0 development. Printout ldns version on unbound -h.
6898 - start of perf tool.
6899 - bugfix to read empty lines from /etc/hosts.
6901 12 February 2008: Wouter
6902 - fixup problem with configure calling itself if ldns-src tarball

6906 - changed library to use ub_ instead of ub_val_ as prefix.
6907 - statistics output text nice.
6908 - etc/hosts handling.
6909 - library function to put logging to a stream.
6910 - set any option interface.

6913 - test program for multiple queries over a TCP channel.
6914 - tpkg test for stream tcp queries.
6915 - unbound replies to multiple TCP queries on a TCP channel.
6916 - fixup misclassification of root referral with NS in answer
6917 when validating a nonrec query.
6919 - layout of manpages, spelling fix in header, manpages process by
6920 makedist, list asynclook and tcpstream tests as ldns-testns
6923 7 February 2008: Wouter
6924 - moved up all current level 2 to be level 3. And 3 to 4.
6925 to make room for new debug level 2 for detailed information
6927 - verbosity level 2. Describes recursion and validation.
6928 - cleaner configure script and fixes for libevent solaris.
6929 - signedness for log output memory sizes in high verbosity.
6931 6 February 2008: Wouter
6932 - clearer explanation of threading configure options.
6933 - fixup asynclook test for nothreading (it creates only one process
6934 to do the extended test).
6935 - changed name of ub_val_result_free to ub_val_resolve_free.
6936 - removes warning message during library linking, renamed
6937 libunbound/unbound.c -> libunbound.c and worker to libworker.
6938 - fallback without EDNS if result is NOTIMPL as well as on FORMERR.
6940 5 February 2008: Wouter
6941 - statistics-interval: seconds option added.
6942 - test for statistics option
6943 - ignore errors making directories, these can occur in parallel builds
6944 - fixup Makefile strip command and libunbound docs typo.
6946 31 January 2008: Wouter
6947 - bg thread/process reads and writes the pipe nonblocking all the time
6948 so that even if the pipe is buffered or so, the bg thread does not
6949 block, and services both pipes and queries.
6951 30 January 2008: Wouter
6952 - check trailing / on chrootdir in checkconf.
6953 - check if root hints and anchor files are in chrootdir.
6954 - no route to host tcp error is verbosity level 2.
6955 - removed unused send_reply_iov. and its configure check.
6956 - added prints of 'remote address is 1.2.3.4 port 53' to errors
6957 from netevent; the basic socket errors.
6959 28 January 2008: Wouter
6960 - fixup uninit use of buffer by libunbound (query id, flags) for
6962 - fixup uninit warning from random.c; also seems to fix sporadic
6963 sigFPE coming out of openssl.
6964 - made openssl entropy warning more silent for library use. Needs
6966 - fixup forgotten locks for rbtree_searches on ctx->query tree.
6967 - random generator cleanup - RND_STATE_SIZE removed, and instead
6968 a super-rnd can be passed at init to chain init random states.
6969 - test also does lock checks if available.
6970 - protect config access in libworker_setup().
6971 - libevent doesn't like comm_base_exit outside of runloop.
6972 - close fds after removing commpoints only (for epoll, kqueue).
6974 25 January 2008: Wouter
6975 - added tpkg for asynclook and library use.
6976 - allows localhost to be queried when as a library.
6977 - fixup race condition between cancel and answer (in case of
6978 really fast answers that beat the cancel).
6979 - please doxygen, put doxygen comment in one place.
6980 - asynclook -b blocking mode and test.
6981 - refactor asynclook, nicer code.
6982 - fixup race problems from opensll in rand init from library, with
6983 a mutex around the rand init.
6984 - fix pass async_id=NULL to _async resolve().
6985 - rewrote _wait() routine, so that it is threadsafe.
6986 - cancelation is threadsafe.
6987 - asynclook extended test in tpkg.
6988 - fixed two races where forked bg process waits for (somehow shared?)
6989 locks, so does not service the query pipe on the bg side.
6990 Now those locks are only held for fg_threads and for bg_as_a_thread.
6992 24 January 2008: Wouter
6993 - tested the cancel() function.
6994 - asynclook -c (cancel) feature.

7002 23 January 2008: Wouter
7003 - removed debug prints from if-auto, verb-algo enables some.
7004 - libunbound QUIT setup, remove memory leaks, when using threads
7005 will share memory for passing results instead of writing it over
7006 the pipe, only writes ID number over the pipe (towards the handler
7007 thread that does process() ).
7009 22 January 2008: Wouter
7010 - library code for async in libunbound/unbound.c.
7011 - fix link testbound.
7012 - fixup exit bug in mini_event.
7013 - background worker query enter and result functions.
7014 - bg query test application asynclook, it looks up multiple
7015 hostaddresses (A records) at the same time.
7017 21 January 2008: Wouter
7018 - libworker work, netevent raw commpoints, write_msg, serialize.
7020 18 January 2008: Wouter
7021 - touch up of manpage for libunbound.
7022 - support for IP_RECVDSTADDR (for *BSD ip4).
7023 - fix for BSD, do not use ip4to6 mapping, make two sockets, once
7024 ip6 and once ip4, uses socket options.
7025 - goodbye ip4to6 mapping.
7026 - update ldns-testpkts with latest version from ldns-trunk.
7027 - updated makedist for relative ldns pathnames.
7028 - library API with more information inside the result structure.
7029 - work on background resolves.

7032 - fixup configure in case -lldns is installed.
7033 - fixup a couple of doxygen warnings, about enum variables.
7034 - interface-automatic now copies the interface address from the
7035 PKT_INFO structure as well.
7036 - manual page with library API, all on one page 'man libunbound'.
7037 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
7039 16 January 2008: Wouter
7040 - incoming queries to the server with TC bit on are replied FORMERR.
7041 - interface-automatic replied the wrong source address on localhost
7042 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
7043 to use ifnum=-1 to mean 'no interface, use kernel route'.
7045 15 January 2008: Wouter
7046 - interface-automatic feature. experimental. Nice for anycast.
7047 - tpkg test for ip6 ancillary data.
7048 - removed debug prints.
7049 - porting experience, define for Solaris, test refined for BSD
7050 compatibility. The feature probably will not work on OpenBSD.
7051 - makedist fixup for ldns-src in build-dir.
7053 14 January 2008: Wouter
7054 - in no debug sets NDEBUG to remove asserts.
7055 - configure --enable-debug is needed for dependency generation
7056 for assertions and for compiler warnings.
7057 - ldns.tgz updated with ldns-trunk (where buffer.h is updated).
7058 - fix lint, unit test in optimize mode.
7059 - default access control allows ::ffff:127.0.0.1 v6mapped localhost.
7061 11 January 2008: Wouter
7062 - man page, warning removed.
7063 - added text describing the use of stub zones for private zones.
7064 - checkconf tests for bad hostnames (IP address), and for doubled
7066 - memory sizes can be given with 'k', 'Kb', or M or G appended.
7068 10 January 2008: Wouter
7069 - typo in example.conf.
7070 - made using ldns-src that is included the package more portable
7071 by linking with .lo instead of .o files in the ldns package.
7072 - nicer do-ip6: yes/no documentation.
7073 - nicer linking of libevent .o files.
7074 - man pages render correctly on solaris.
7076 9 January 2008: Wouter
7077 - fixup openssl RAND problem, when the system is not configured to
7078 give entropy, and the rng needs to be seeded.
7080 8 January 2008: Wouter
7081 - print median and quartiles with extensive logging.
7083 4 January 2008: Wouter
7084 - document misconfiguration in private network.
7086 2 January 2008: Wouter
7087 - fixup typo in requirements.
7088 - document that 'refused' is a better choice than 'drop' for
7089 the access control list, as refused will stop retries.
7091 7 December 2007: Wouter
7092 - unbound-host has a -d option to show what happens. This can help
7093 with debugging (why do I get this answer).
7094 - fixup CNAME handling, on nodata, sets and display canonname.
7095 - dot removed from CNAME display.
7096 - respect -v for NXDOMAINs.
7097 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
7098 - size_t to int for portability of the header file.
7099 - fixup bogus handling.
7100 - dependencies and lint for unbound-host.
7102 6 December 2007: Wouter
7103 - library resolution works in foreground mode, unbound-host app
7105 - unbound-host prints rdata using ldns.
7106 - unbound-host accepts trust anchors, and prints validation
7107 information when you give -v.
7109 5 December 2007: Wouter
7110 - locking in context_new() inside the function.
7111 - setup of libworker.
7113 4 December 2007: Wouter
7114 - minor Makefile fixup.
7115 - moved module-stack code out of daemon/daemon into services/modstack,
7116 preparing for code-reuse.
7117 - move context into own header file.
7118 - context query structure.
7119 - removed unused variable pwd from checkconf.
7120 - removed unused assignment from outside netw.
7121 - check timeval length of string.
7122 - fixup error in val_utils getsigner.
7123 - fixup same (*var) error in netblocktostr.
7124 - fixup memleak on parse error in localzone.
7125 - fixup memleak on packet parse error.
7126 - put ; after union in parser.y.
7127 - small hardening in iter_operate against iq==NULL.
7128 - hardening, if error reply with rcode=0 (noerror) send servfail.
7129 - fixup same (*var) error in find_rrset in msgparse, was harmless.
7130 - check return value of evtimer_add().
7131 - fixup lockorder in lruhash_reclaim(), building up a list of locked
7132 entries one at a time. Instead they are removed and unlocked.
7133 - fptr_wlist for markdelfunc.
7134 - removed is_locked param from lruhash delkeyfunc.
7135 - moved bin_unlock during bin_split purely to please.
7137 3 December 2007: Wouter
7138 - changed checkconf/ to smallapp/ to make room for more support tools.
7139 (such as unbound-host).
7140 - install dirs created with -m 755 because they need to be accessible.
7141 - library extensive featurelist added to TODO.
7142 - please doxygen, lint.
7143 - library test application, with basic functionality.
7144 - fix for building in a subdirectory.
7145 - link lib fix for Leopard.
7147 30 November 2007: Wouter
7148 - makefile that creates libunbound.la, basic file or libunbound.a
7149 when creating static executables (no libtool).
7152 29 November 2007: Wouter
7153 - 0.9 public API start.
7155 28 November 2007: Wouter
7156 - Changeup plan for 0.8 - no complication needed, a simple solution
7157 has been chosen for authoritative features.
7158 - you can use single quotes in the config file, so it is possible
7159 to specify TXT records in local data.
7160 - fixup small memory problem in implicit transparent zone creation.
7161 - test for implicit zone creation and multiple RR RRsets local data.
7162 - local-zone nodefault test.
7163 - show testbound testlist on commit.
7164 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
7165 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
7167 - nicer verbosity: 0 and 1 levels.
7168 - lower nonRDquery chance of eliciting wrongly typed validation
7169 requiring message from the cache.
7170 - fix for nonRDquery validation typing; nodata is detected when
7171 SOA record in auth section (all validation-requiring nodata messages
7172 have a SOA record in authority, so this is OK for the validator),
7173 and NS record is needed to be a referral.
7174 - duplicate checking when adding NSECs for a CNAME, and test.
7175 - created svn tag 0.8, after completing testbed tests.
7177 27 November 2007: Wouter
7178 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
7179 - set size of msgparse lookup table to 32, from 1024, so that its size
7180 is below the 2048 regional large size threshold, and does not cause
7181 a call to malloc when a message is parsed.
7182 - update of memstats tool to print number of allocation calls.
7183 This is what is taking time (not space) and indicates the avg size
7184 of the allocations as well. region_alloc stat is removed.
7186 22 November 2007: Wouter
7187 - noted EDNS in-the-middle dropping trouble as a TODO.
7188 At this point theoretical, no user trouble has been reported.
7189 - added all default AS112 zones.
7190 - answers from local zone content.
7191 * positive answer, the rrset in question
7192 * nodata answer (exist, but not that type).
7193 * nxdomain answer (domain does not exist).
7194 * empty-nonterminal answer.
7195 * But not: wildcard, nsec, referral, rrsig, cname/dname,
7196 or additional section processing, NS put in auth.
7197 - test for correct working of static and transparent and couple
7198 of important defaults (localhost, as112, reverses).
7199 Also checks deny and refuse settings.
7200 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
7202 21 November 2007: Wouter
7203 - local zone internal data setup.
7205 20 November 2007: Wouter
7206 - 0.8 - str2list config support for double string config options.
7207 - local-zone and local-data options, config storage and documentation.
7209 19 November 2007: Wouter
7210 - do not downcase NSEC and RRSIG for verification. Follows
7211 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
7212 - fixup leaking unbound daemons at end of tests.
7213 - README file updated.
7214 - nice libevent not found error.
7215 - README talks about gnu make.
7216 - 0.8: unit test for addr_mask and fixups for it.
7217 and unit test for addr_in_common().
7218 - 0.8: access-control config file element.
7219 and unit test rpl replay file.
7220 - 0.8: fixup address reporting from netevent.
7222 16 November 2007: Wouter
7223 - privilege separation is not needed in unbound at this time.
7224 TODO item marked as such.
7225 - created beta-0.7 branch for support.
7226 - tagged 0.7 for beta release.
7227 - moved trunk to 0.8 for 0.8(auth features) development.
7228 - 0.8: access control list setup.
7230 15 November 2007: Wouter
7231 - review fixups from Jelte.
7233 14 November 2007: Wouter
7234 - testbed script does not recreate configure, since its in svn now.
7235 - fixup checkconf test so that it does not test
7236 /etc/unbound/unbound.conf.
7239 13 November 2007: Wouter
7240 - remove debug print.
7241 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
7243 12 November 2007: Wouter
7244 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
7246 - bugreports to unbound-bugs@nlnetlabs.nl
7247 - fixup testbound so it exits cleanly.
7248 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
7250 9 November 2007: Wouter
7251 - took ldns snapshot in repo.
7252 - default config file is /etc/unbound/unbound.conf.
7253 If it doesn't exist, it is installed with the doc/example.conf file.
7254 The file is not deleted on uninstall.
7255 - default listening is not all, but localhost interfaces.
7257 8 November 2007: Wouter
7258 - Fixup chroot and drop user privileges.
7259 - new L root ip address in default hints.
7261 1 November 2007: Wouter
7262 - Fixup of crash on reload, due to anchors in env not NULLed after
7263 dealloc during deinit.
7264 - Fixup of chroot call. Happens after privileges are dropped, so
7265 that checking the passwd entry still works.
7266 - minor touch up of clear() hashtable function.
7267 - VERB_DETAIL prints out what chdir, username, chroot is being done.
7268 - when id numbers run out, caches are cleared, as in design notes.
7269 Tested with a mock setup with very few bits in id, it worked.
7270 - harden-dnssec-stripped: yes is now default. It insists on dnssec
7271 data for trust anchors. Included tests for the feature.
7273 31 October 2007: Wouter
7274 - cache-max-ttl config option.
7275 - building outside sourcedir works again.
7276 - defaults more secure:
7278 chroot: "/etc/unbound"
7279 The operator can override them to be less secure ("") if necessary.
7280 - fix horrible oversight in sorting rrset references in a message,
7281 sort per reference key pointer, not on referencepointer itself.
7282 - pidfile: "/etc/unbound/unbound.pid" is now the default.
7283 - tests changed to reflect the updated default.
7284 - created hashtable clear() function that respects locks.
7286 30 October 2007: Wouter
7287 - fixup assertion failure that relied on compressed names to be
7288 smaller than uncompressed names. A packet from comrite.com was seen
7289 to be compressed to a larger size. Added it as unit test.
7290 - quieter logging at low verbosity level for common tcp messages.
7291 - no greedy TTL update.
7293 23 October 2007: Wouter
7294 - fixup (grand-)parent problem for dnssec-lameness detection.
7295 - fixup tests to do additional section processing for lame replies,
7296 since the detection needs that.
7297 - no longer trust in query section in reply during dnssec lame detect.
7298 - dnssec lameness does not make the server never ever queried, but
7299 non-preferred. If no other servers exist or answer, the dnssec lame
7300 server is used; the fastest dnssec lame server is chosen.
7301 - added test then when trust anchor cannot be primed (nodata), the
7302 insecure mode from unbound works.
7303 - Fixup max queries per thread, any more are dropped.
7305 22 October 2007: Wouter
7306 - added donotquerylocalhost config option. Can be turned off for
7308 - ISO C compat changes.
7309 - detect RA-no-AA lameness, as LAME.
7310 - DNSSEC-lameness detection, as LAME.
7311 See notes in requirements.txt for choices made.
7312 - tests for lameness detection.
7313 - added all to make test target; need unbound for fwd tests.
7314 - testbound does not pollute /etc/unbound.
7316 19 October 2007: Wouter
7317 - added configure (and its files) to svn, so that the trunk is easier
7318 to use. ./configure, config.guess, config.sub, ltmain.sh,
7320 - added yacc/lex generated files, util/configlexer.c,
7321 util/configparser.c util/configparser.h, to svn.
7322 - without lex no attempt to use it.
7323 - unsecure response validation collated into one block.
7324 - remove warning about const cast of cfgfile name.
7325 - outgoing-interfaces can be different from service interfaces.
7326 - ldns-src configure is done during unbound configure and
7327 ldns-src make is done during unbound make, and so inherits the
7328 make arguments from the unbound make invocation.
7329 - nicer error when libevent problem causes instant exit on signal.
7330 - read root hints from a root hint file (like BIND does).
7332 18 October 2007: Wouter
7333 - addresses are logged with errors.
7334 - fixup testcode fake event to remove pending before callback
7335 since the callback may create new pending items.
7336 - tests updated because retries are now in iterator module.
7337 - ldns-testpkts code is checked for differences between unbound
7338 and ldns by makedist.sh.
7339 - ldns trunk from today added in svn repo for fallback in case
7340 no ldns is installed on the system.
7341 make download_ldns refreshes the tarball with ldns svn trunk.
7342 - ldns-src.tar.gz is used if no ldns is found on the system, and
7343 statically linked into unbound.
7344 - start of regional allocator code.
7345 - regional uses less memory and variables, simplified code.
7346 - remove of region-allocator.
7347 - alloc cache keeps a cache of recently released regional blocks,
7349 - make unit test cleanly free memory.
7351 17 October 2007: Wouter
7352 - fixup another cycle detect and ns-addr timeout resolution bug.
7353 This time by refusing delegations from the cache without addresses
7354 when resolving a mandatory-glue nameserver-address for that zone.
7355 We're going to have to ask a TLD server anyway; might as well be
7356 the TLD server for this name. And this resolves a lot of cases where
7357 the other nameserver names lead to cycles or are not available.
7358 - changed random generator from random(3) clone to arc4random wrapped
7359 for thread safety. The random generator is initialised with
7360 entropy from the system.
7361 - fix crash where failure to prime DNSKEY tried to print null pointer
7363 - removed some debug prints, only verb_algo (4) enables them.
7364 - fixup test; new random generator took new paths; such as one
7365 where no scripted answer was available.
7366 - mark insecure RRs as insecure.
7367 - fixup removal of nonsecure items from the additional.
7368 - reduced timeout values to more realistic, 376 msec (262 msec has
7369 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
7370 - server selection failover to next server after timeout (376 msec).
7372 16 October 2007: Wouter
7373 - no malloc in log_hex.
7374 - assertions around system calls.
7375 - protect against gethostname without ending zero.
7376 - ntop output is null terminated by unbound.
7377 - pidfile content null termination
7378 - various snprintf use sizeof(stringbuf) instead of fixed constant.
7379 - changed loopdetect % 8 with & 0x7 since % can become negative for
7380 weird negative input and particular interpretation of integer math.
7381 - dname_pkt_copy checks length of result, to protect result buffers.
7382 prints an error, this should not happen. Bad strings should have
7383 been rejected earlier in the program.
7384 - remove a size_t underflow from msgreply size func.
7386 15 October 2007: Wouter
7388 - fix IP6 TCP, wrong definition check. With test package.
7389 - fixup the fact that the query section was not compressed to,
7390 the code was there but was called by value instead of by reference.
7391 And test for the case, uses xxd and nc.
7392 - more portable ip6 check for sockaddr types.
7394 8 October 2007: Wouter
7395 - --disable-rpath option in configure for 64bit systems with
7396 several dynamic lib dirs.
7398 7 October 2007: Wouter
7399 - fixup tests for no AD bit in non-DO queries.
7400 - test that makes sure AD bit is not set on non-DO query.
7402 6 October 2007: Wouter
7403 - removed logfile open early. It did not have the proper permissions;
7404 it was opened as root instead of the user. And we cannot change user
7405 id yet, since chroot and bind ports need to be done.
7406 - callback checks for event callbacks done from mini_event. Because
7407 of deletions cannot do this from netevent. This means when using
7408 libevent the protection does not work on event-callbacks.
7409 - fixup too small reply (did not zero counts).
7410 - fixup reply no longer AD bit when query without DO bit.
7412 5 October 2007: Wouter
7413 - function pointer whitelist.
7415 4 October 2007: Wouter
7416 - overwrite sensitive random seed value after use.
7417 - switch to logfile very soon if not -d (console attached).
7418 - error messages do not reveal the trustanchor contents.
7419 - start work on function pointer whitelists.
7421 3 October 2007: Wouter
7422 - fix for multiple empty nonterminals, after multiple DSes in the
7424 - mesh checks if modules are looping, and stops them.
7425 - refetch with CNAMEd nameserver address regression test added.
7426 - fixup line count bug in testcode, so testbound prints correct line
7427 number with parse errors.
7428 - unit test for multiple ENT case.
7429 - fix for cname out of validated unsec zone.
7430 - fixup nasty id=0 reuse. Also added assertions to detect its
7431 return (the assertion catches in the existing test cases).
7433 1 October 2007: Wouter
7434 - skip F77, CXX, objC tests in configure step.
7435 - fixup crash in refetch glue after a CNAME.
7436 and protection against similar failures (with error print).
7438 28 September 2007: Wouter
7439 - test case for unbound-checkconf, fixed so it also checks the
7440 interface: statements.
7442 26 September 2007: Wouter
7443 - SIGHUP will reopen the log file.
7444 - Option to log to syslog.
7445 - please lint, fixup tests (that went to syslog on open, oops).
7446 - config check program.
7448 25 September 2007: Wouter
7449 - tests for NSEC3. Fixup bitmap checks for NSEC3.
7450 - positive ANY response needs to check if wildcard expansion, and
7451 check that original data did not exist.
7452 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
7453 delegation, for abuse of child zone apex nsec3.
7454 - create 0.5 release tag.
7456 24 September 2007: Wouter
7457 - do not make test programs by default.
7458 - But 'make test' will perform all of the tests.
7459 - Advertise builtin select libevent alternative when no libevent
7461 - signit can generate NSEC3 hashes, for generating tests.
7462 - multiple nsec3 parameters in message test.
7463 - too high nsec3 iterations becomes insecure test.
7465 21 September 2007: Wouter
7466 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
7467 - fixup testcode lock safety (port FreeBSD).
7468 - removes subscript has type char warnings (port Solaris 9).
7469 - fixup of field with format type to int (port MacOS/X intel).
7470 - added test for infinite loop case in nonRD answer validation.
7471 It was a more general problem, but hard to reproduce. When an
7472 unsigned rrset is being validated and the key fetched, the DS
7473 sequence is followed, but if the final name has no DS, then no
7474 proof is possible - the signature has been stripped off.
7476 20 September 2007: Wouter
7477 - fixup and test for NSEC wildcard with empty nonterminals.
7478 - makedist.sh fixup for svn info.
7479 - acl features request in plan.
7480 - improved DS empty nonterminal handling.
7481 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
7482 proof anyway, which succeeds in ANS failure case.
7483 - striplab protection in case it becomes -1.
7484 - plans for static and blacklist config.
7486 19 September 2007: Wouter
7487 - comments about non-packed usage.
7488 - plan for overload support in 0.6.
7489 - added testbound tests for a failed resolution from the logs
7490 and for failed prime when missing glue.
7491 - fixup so useless delegation points are not returned from the
7492 cache. Also the safety belt is used if priming fails to complete.
7493 - fixup NSEC rdata not to be lowercased, bind compat.
7495 18 September 2007: Wouter
7496 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
7497 - validator prints subtype classification for debug.
7499 17 September 2007: Wouter
7500 - NSEC3 hash cache unit test.
7501 - validator nsec3 nameerror test.
7503 14 September 2007: Wouter
7504 - nsec3 nodata proof, nods proof, wildcard proof.
7505 - nsec3 support for cname chain ending in noerror or nodata.
7506 - validator calls nsec3 proof routines if no NSECs prove anything.
7507 - fixup iterator bug where it stored the answer to a cname under
7508 the wrong qname into the cache. When prepending the cnames, the
7509 qname has to be reset to the original qname.
7511 13 September 2007: Wouter
7512 - nsec3 find matching and covering, ce proof, prove namerror msg.
7514 12 September 2007: Wouter
7515 - fixup of manual page warnings, like for NSD bugreport.
7516 - nsec3 work, config, max iterations, filter, and hash cache.
7518 6 September 2007: Wouter
7519 - fixup to find libevent on mac port install.
7520 - fixup size_t vs unsigned portability in validator/sigcrypt.
7521 - please compiler on different platforms, for unreachable code.
7523 - pthread_rwlock type is optional, in case of old pthread libs.
7525 5 September 2007: Wouter
7526 - cname, name error validator tests.
7527 - logging of qtype ANY works.
7528 - ANY type answers get RRSIG in answer section of replies (but not
7529 in other sections, unless DO bit is on).
7530 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
7531 - DS and noDS referral validation test.
7532 - if you configure many trust anchors, parent trust anchors can
7533 securely deny existence of child trust anchors, if validated.
7534 - not all *.name NSECs are present because a wildcard was matched,
7535 and *.name NSECs can prove nodata for empty nonterminals.
7536 Also, for wildcard name NSECs, check they are not from the parent
7537 zone (for wildcarded zone cuts), and check absence of CNAME bit,
7539 - configure option for memory allocation debugging.
7540 - port configure option for memory allocation to solaris10.
7542 4 September 2007: Wouter
7543 - fixup of Leakage warning when serviced queries processed multiple
7544 callbacks for the same query from the same server.
7545 - testbound removes config file from /tmp on failed exit.
7546 - fixup for referral cleanup of the additional section.
7547 - tests for cname, referral validation.
7548 - neater testbound tpkg output.
7549 - DNAMEs no longer match their apex when synthesized from the cache.
7550 - find correct signer name for DNAME responses.
7551 - wildcarded DNAME test and fixup code to detect.
7552 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
7553 So that wildcarded CNAMEs get their NSEC with them to the answer.
7554 - test for a CNAME to a DNAME to a CNAME to an answer, all from
7555 different domains, for key fetching and signature checking of
7558 3 September 2007: Wouter
7559 - Fixed error in iterator that would cause assertion failure in
7560 validator. CNAME to a NXDOMAIN response was collated into a response
7561 with both a CNAME and the NXDOMAIN rcode. Added a test that the
7562 rcode is changed to NOERROR (because of the CNAME).
7563 - timeout on tcp does not lead to spurious leakage detect.
7564 - account memory for name of lame zones, so that memory leakages does
7565 not show lame cache growth as a leakage growth.
7566 - config setting for lameness cache expressed in bytes, instead of
7568 - tool too summarize allocations per code line.
7570 31 August 2007: Wouter
7571 - can read bind trusted-keys { ... }; files, in a compatibility mode.
7572 - iterator should not detach target queries that it still could need.
7573 the protection against multiple outstanding queries is moved to a
7574 current_query num check.
7575 - validator nodata, positive, referral tests.
7576 - dname print can print '*' wildcard.
7578 30 August 2007: Wouter
7579 - fixup override date config option.
7580 - config options to control memory usage.
7581 - caught bad free of un-alloced data in worker_send error case.
7582 - memory accounting for key cache (trust anchors and temporary cache).
7583 - memory accounting fixup for outside network tcp pending waits.
7584 - memory accounting fixup for outside network tcp callbacks.
7585 - memory accounting for iterator fixed storage.
7586 - key cache size and slabs config options.
7587 - lib crypto cleanups at exit.
7589 29 August 2007: Wouter
7590 - test tool to sign rrsets for testing validator with.
7591 - added RSA and DSA test keys, public and private pairs, 512 bits.
7592 - default configuration is with validation enabled.
7593 Only a trust-anchor needs to be configured for DNSSEC to work.
7594 - do not convert to DER for DSA signature verification.
7595 - validator replay test file, for a DS to DNSKEY DSA key prime and
7598 28 August 2007: Wouter
7599 - removed double use for udp buffers, that could fail,
7600 instead performs a malloc to do the backup.
7601 - validator validates referral messages, by validating all the rrsets
7602 and stores the rrsets in the cache. Further referral (nonRD queries)
7603 replies are made from the rrset cache directly. Unless unchecked
7604 rrsets are encountered, there are then validated.
7605 - enforce that signing is done by a parent domain (or same domain).
7606 - adjust TTL downwards if rrset TTL bigger than signature allows.
7607 - permissive mode feature, sets AD bit for secure, but bogus does
7608 not give servfail (bogus is changed into indeterminate).
7609 - optimization of rrset verification. rr canonical sorting is reused,
7610 for the same rrset. canonical rrset image in buffer is reused for
7612 - if the rrset is too big (64k exactly + large owner name) the
7613 canonicalization routine will fail if it does not fit in buffer.
7614 - faster verification for large sigsets.
7615 - verb_detail mode reports validation failures, but not the entire
7616 algorithm for validation. Key prime failures are reported as
7619 27 August 2007: Wouter
7620 - do not garble the edns if a cache answer fails.
7621 - answer norecursive from cache if possible.
7622 - honor clean_additional setting when returning secure non-recursive
7624 - do not store referral in msg cache for nonRD queries.
7625 - store verification status in the rrset cache to speed up future
7627 - mark rrsets indeterminate and insecure if they are found to be so.
7628 and store this in the cache.
7630 24 August 2007: Wouter
7631 - message is bogus if unsecure authority rrsets are present.
7632 - val-clean-additional option, so you can turn it off.
7633 - move rrset verification out of the specific proof types into one
7634 routine. This makes the proof routines prettier.
7635 - fixup cname handling in validator, cname-to-positive and cname-to-
7637 - Do not synthesize DNSKEY and DS responses from the rrset cache if
7638 the rrset is from the additional section. Signatures may have
7639 fallen off the packet, and cause validation failure.
7640 - more verbose signature date errors (with the date attached).
7641 - increased default infrastructure cache size. It is important for
7642 performance, and 1000 entries are only 212k (or a 400 k total cache
7643 size). To 10000 entries (for 2M entries, 4M cache size).
7645 23 August 2007: Wouter
7646 - CNAME handling - move needs_validation to before val_new().
7647 val_new() setups the chase-reply to be an edited copy of the msg.
7648 new classification, and find signer can find for it.
7649 removal of unsigned crap from additional, and query restart for
7651 - refuse to follow wildcarded DNAMEs when validating.
7652 But you can query for qtype ANY, or qtype DNAME and validate that.
7654 22 August 2007: Wouter
7656 - review - use val_error().
7658 21 August 2007: Wouter
7659 - ANY response validation.
7660 - store security status in cache.
7661 - check cache security status and either send the query to be
7662 validated, return the query to client, or send servfail to client.
7663 Sets AD bit on validated replies.
7664 - do not examine security status on an error reply in mesh_done.
7665 - construct DS, DNSKEY messages from rrset cache.
7666 - manual page entry for override-date.
7668 20 August 2007: Wouter
7669 - validate and positive validation, positive wildcard NSEC validation.
7670 - nodata validation, nxdomain validation.
7672 18 August 2007: Wouter
7673 - process DNSKEY response in FINDKEY state.
7675 17 August 2007: Wouter
7676 - work on DS2KE routine.
7677 - val_nsec.c for validator NSEC proofs.
7678 - unit test for NSEC bitmap reading.
7679 - dname iswild and canonical_compare with unit tests.
7681 16 August 2007: Wouter
7683 - latest release libevent 1.3c and 1.3d have threading fixed.
7684 - key entry fixup data pointer and ttl absolute.
7685 - This makes a key-prime succeed in validator, with DS or DNSKEY as
7687 - fixup canonical compare byfield routine, fix bug and also neater.
7688 - fixed iterator response type classification for queries of type
7690 dig ANY gives sometimes NS rrset in AN and NS section, and parser
7691 removes the NS section duplicate. dig NS gives sometimes the NS
7692 in the answer section, as referral.
7693 - validator FINDKEY state.
7695 15 August 2007: Wouter
7696 - crypto calls to verify signatures.
7697 - unit test for rrsig verification.
7699 14 August 2007: Wouter
7700 - default outgoing ports changed to avoid port 2049 by default.
7701 This port is widely blocked by firewalls.
7702 - count infra lameness cache in memory size.
7703 - accounting of memory improved
7704 - outbound entries are allocated in the query region they are for.
7705 - extensive debugging for memory allocations.
7706 - --enable-lock-checks can be used to enable lock checking.
7707 - protect undefs in config.h from autoheaders ministrations.
7708 - print all received udp packets. log hex will print on multiple
7710 - fixed error in parser with backwards rrsig references.
7711 - mark cycle targets for iterator did not have CD flag so failed
7714 13 August 2007: Wouter
7715 - fixup makefile, if lexer is missing give nice error and do not
7716 mess up the dependencies.
7717 - canonical compare routine updated.
7718 - canonical hinfo compare.
7719 - printout list of the queries that the mesh is working on.
7721 10 August 2007: Wouter
7722 - malloc and free overrides that track total allocation and frees.
7723 for memory debugging.
7724 - work on canonical sort.
7726 9 August 2007: Wouter
7727 - canonicalization, signature checks
7728 - dname signature label count and unit test.
7729 - added debug heap size print to memory printout.
7730 - typo fixup in worker.c
7731 - -R needed on solaris.
7732 - validator override option for date check testing.
7734 8 August 2007: Wouter
7735 - ldns _raw routines created (in ldns trunk).
7736 - sigcrypt DS digest routines
7737 - val_utils uses sigcrypt to perform signature cryptography.
7738 - sigcrypt keyset processing
7740 7 August 2007: Wouter
7741 - security status type.
7742 - security status is copied when rdata is equal for rrsets.
7743 - rrset id is updated to invalidate all the message cache entries
7744 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
7746 - val_sigcrypt file for validator signature checks.
7748 6 August 2007: Wouter
7749 - key cache for validator.
7750 - moved isroot and dellabel to own dname routines, with unit test.
7752 3 August 2007: Wouter
7754 - scrubber check section of lame NS set.
7755 - trust anchors can be in config file or read from zone file,
7756 DS and DNSKEY entries.
7757 - unit test trust anchor storage.
7758 - trust anchors converted to packed rrsets.
7759 - key entry definition.
7761 2 August 2007: Wouter
7762 - configure change for latest libevent trunk version (needs -lrt).
7763 - query_done and walk_supers are moved out of module interface.
7764 - fixup delegation point duplicates.
7765 - fixup iterator scrubber; lame NS set is let through the scrubber
7766 so that the classification is lame.
7767 - validator module exists, and does nothing but pass through,
7768 with calling of next module and return.
7771 1 August 2007: Wouter
7772 - set version to 0.5
7773 - module work for module to module interconnections.
7774 - config of modules.
7775 - detect cycle takes flags.
7777 31 July 2007: Wouter
7781 30 July 2007: Wouter
7782 - changed random state init, so that sequential process IDs are not
7783 cancelled out by sequential thread-ids in the random number seed.
7784 - the fwd_three test, which sends three queries to unbound, and
7785 unbound is kept waiting by ldns-testns for 3 seconds, failed
7786 because the retry timeout for default by unbound is 3 seconds too,
7787 it would hit that timeout and fail the test. Changed so that unbound
7788 is kept waiting for 2 seconds instead.
7790 27 July 2007: Wouter
7791 - removed useless -C debug option. It did not work.
7792 - text edit of documentation.
7793 - added doc/CREDITS file, referred to by the manpages.
7796 26 July 2007: Wouter
7797 - cycle detection, for query state dependencies. Will attempt to
7798 circumvent the cycle, but if no other targets available fails.
7799 - unit test for AXFR, IXFR response.
7800 - test for cycle detection.
7802 25 July 2007: Wouter
7803 - testbound read ADDRESS and check it.
7804 - test for version.bind and friends.
7805 - test for iterator chaining through several referrals.
7806 - test and fixup for refetch for glue. Refetch fails if glue
7807 is still not provided.
7809 24 July 2007: Wouter
7810 - Example section in config manual.
7811 - Addr stored for range and moment in replay.
7813 20 July 2007: Wouter
7814 - Check CNAME chain before returning cache entry with CNAMEs.
7815 - Option harden-glue, default is on. It will discard out of zone
7816 data. If disabled, performance is faster, but spoofing attempts
7817 become a possibility. Note that still normalize scrubbing is done,
7818 and that the potentially spoofed data is used for infrastructure
7819 and not returned to the client.
7820 - if glue times out, refetch by asking parent of delegation again.
7821 Much like asking for DS at the parent side.
7822 - TODO items from forgery-resilience draft.
7823 and on memory handling improvements.
7824 - renamed module_event_timeout to module_event_noreply.
7825 - memory reporting code; reports on memory usage after handling
7826 a network packet (not on cache replies).
7828 19 July 2007: Wouter
7829 - shuffle NS selection when getting nameserver target addresses.
7830 - fixup of deadlock warnings, yield cpu in checklock code so that
7831 freebsd scheduler selects correct process to run.
7832 - added identity and version config options and replies.
7833 - store cname messages complete answers.
7835 18 July 2007: Wouter
7836 - do not query addresses, 127.0.0.1, and ::1 by default.
7838 17 July 2007: Wouter
7839 - forward zone options in config file.
7840 - forward per zone in iterator. takes precedence over stubs.
7841 - fixup commithooks.
7842 - removed forward-to and forward-to-port features, subsumed by
7844 - fix parser to handle absent server: clause.
7845 - change untrusted rrset test to account for scrubber that is now
7846 applied during the test (which removes the poison, by the way).
7847 - feature, addresses can be specified with @portnumber, like nsd.conf.
7848 - test config files changed over to new forwarder syntax.
7850 27 June 2007: Wouter
7851 - delete of mesh does a postorder traverse of the tree.
7852 - found and fixed a memory leak. For TTL=0 messages, that would
7853 not be cached, instead the msg-replyinfo structure was leaked.
7854 - changed server selection so it will filter out hosts that are
7855 unresponsive. This is defined as a host with the maximum rto value.
7856 This means that unbound tried the host for retries up to 120 secs.
7857 The rto value will time out after host-ttl seconds from the cache.
7858 This keeps such unresolvable queries from taking up resources.
7859 - utility for keeping histogram.
7861 26 June 2007: Wouter
7862 - mesh is called by worker, and iterator uses it.
7863 This removes the hierarchical code.
7864 QueryTargets state and Finished state are merged for iterator.
7865 - forwarder mode no longer sets AA bit on first reply.
7866 - rcode in walk_supers is not needed.
7868 25 June 2007: Wouter
7870 - error encode routine for ease.
7872 22 June 2007: Wouter
7873 - removed unused _node iterator value from rbtree_t. Takes up space.
7874 - iterator can handle querytargets state without a delegation point
7875 set, so that a priming(stub) subquery error can be handled.
7876 - iterator stores if it is priming or not.
7877 - log_query_info() neater logging.
7878 - changed iterator so that it does not alter module_qstate.qinfo
7879 but keeps a chase query info. Also query_flags are not altered,
7880 the iterator uses chase_flags.
7881 - fixup crash in case no ports for the family exist.
7883 21 June 2007: Wouter
7884 - Fixup secondary buffer in case of error callback.
7885 - cleanup slumber list of runnable states.
7886 - module_subreq_depth fails to work in slumber list.
7887 - fixup query release for cached results to sub targets.
7888 - neater error for tcp connection failure, shows addr in verbose.
7889 - rbtree_init so that it can be used with preallocated memory.
7891 20 June 2007: Wouter
7892 - new -C option to enable coredumps after forking away.
7894 - fixup CNAME generation by scrubber, and memory allocation of it.
7895 - fixup deletion of serviced queries when all callbacks delete too.
7896 - set num target queries to 0 when you move them to slumber list.
7897 - typo in check caused subquery errors to be ignored, fixed.
7898 - make lint happy about rlim_t.
7899 - freeup of modules after freeup of module-states.
7900 - duplicate replies work, this uses secondary udp buffer in outnet.
7902 19 June 2007: Wouter
7903 - nicer layout in stats.c, review 0.3 change.
7904 - spelling improvement, review 0.3 change.
7905 - uncapped timeout for server selection, so that very fast or slow
7906 servers will stand out from the rest.
7907 - target-fetch-policy: "3 2 1 0 0" config setting.
7908 - fixup queries answered without RD bit (for root prime results).
7909 - refuse AXFR and IXFR requests.
7910 - fixup RD flag in error reply from iterator. fixup RA flag from
7912 - fixup encoding of very short edns buffer sizes, now sets TC bit.
7913 - config options harden-short-bufsize and harden-large-queries.
7915 18 June 2007: Wouter
7916 - same, move subqueries to slumber list when first has resolved.
7917 - fixup last fix for duplicate callbacks.
7918 - another offbyone in targetcounter. Also in Java prototype by the way.
7920 15 June 2007: Wouter
7921 - if a query asks to be notified of the same serviced query result
7922 multiple times, this will succeed. Only one callback will happen;
7923 multiple outbound-list entries result (but the double cleanup of it
7925 - when iterator moves on due to CNAME or referral, it will remove
7926 the subqueries (for other targets). These are put on the slumber
7928 - state module wait subq is OK with no new subqs, an old one may have
7929 stopped, with an error, and it is still waiting for other ones.
7930 - if a query loops, halt entire query (easy way to clean up properly).
7932 14 June 2007: Wouter
7933 - num query targets was > 0 , not >= 0 compared, so that fetch
7934 policy of 0 did nothing.
7936 13 June 2007: Wouter
7937 - debug option: configure --enable-static-exe for compile where
7938 ldns and libevent are linked statically. Default is off.
7939 - make install and make uninstall. Works with static-exe and without.
7940 installation of unbound binary and manual pages.
7941 - alignment problem fix on solaris 64.
7942 - fixup address in case of TCP error.
7944 12 June 2007: Wouter
7945 - num target queries was set to 0 at a bad time. Default it to 0 and
7946 increase as target queries are done.
7947 - synthesize CNAME and DNAME responses from the cache.
7948 - Updated doxygen config for doxygen 1.5.
7949 - aclocal newer version.
7950 - doxygen 1.5 fixes for comments (for the strict check on docs).
7952 11 June 2007: Wouter
7953 - replies on TCP queries have the address field set in replyinfo,
7954 for serviced queries, because the initiator does not know that
7955 a TCP fallback has occured.
7956 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
7957 if qtype directly queries for the type (and then only show that
7958 'unknown type' in the answer section).
7959 - fixed message parsing where rrsigs on their own would be put
7960 in the signature list over the rrsig type.
7963 - fixup error in double linked list insertion for subqueries and
7964 for outbound list of serviced queries for iterator module.
7965 - nicer printout of outgoing port selection.
7966 - fixup cname target readout.
7967 - nicer debug output.
7968 - fixup rrset counts when prepending CNAMEs to the answer.
7969 - fixup rrset TTL for prepended CNAMEs.
7970 - process better check for looping modules, and which submodule to
7972 - subreq insertion code fixup for slumber list.
7973 - VERB_DETAIL, verbosity: 2 level gives short but readable output.
7974 VERB_ALGO, verbosity: 3 gives extensive output.
7975 - fixup RA bit in cached replies.
7976 - fixup CNAME responses from the cache no longer partial response.
7977 - error in network send handled without leakage.
7978 - enable ip6 from config, and try ip6 addresses if available,
7979 if ip6 is not connected, skips to next server.
7982 - iterator state finished.
7983 - subrequests without parent store in cache and stop.
7984 - worker slumber list for ongoing promiscuous queries.

7987 - priming gives LAME result, returns SERVFAIL.
7988 - debug routine to print dns_msg as handled by iterator.
7989 - memleak in config file stubs fixup.
7990 - more small bugs, in scrubber, query compare no ID for lookup,
7991 in dname validation for NS targets.
7992 - sets entry.key for new special allocs.
7993 - lognametypeclass can display unknown types and classes.
7996 - random selection of equally preferred nameserver targets.
7997 - reply info copy routine. Reuses existing code.
7998 - cache lameness in response handling.
7999 - do not touch qstate after worker_process_query because it may have
8000 been deleted by that routine.
8001 - Prime response state.
8002 - Process target response state.
8003 - some memcmp changed to dname_compare for case preservation.
8006 - normalize incoming messages. Like unbound-java, with CNAME chain
8007 checked, DNAME checked, CNAME's synthesized, glue checked.
8008 - sanitize incoming messages.
8009 - split msgreply encode functions into own file msgencode.c.
8010 - msg_parse to queryinfo/replyinfo conversion more versatile.
8011 - process_response, classify response, delegpt_from_message.
8014 - querytargets state.
8015 - dname_subdomain_c() routine.
8016 - server selection, based on RTT. ip6 is filtered out if not available,
8017 and lameness is checked too.
8018 - delegation point copy routine.
8021 - removed FLAG_CD from message and rrset caches. This was useful for
8022 an agnostic forwarder, but not for a sophisticated (trust value per
8023 rrset enabled) cache.
8024 - iterator response typing.
8025 - iterator cname handle.
8026 - iterator prime start.
8028 - processInitRequest and processInitRequest2.
8029 - cache synthesizes referral messages, with DS and NSEC.

8038 - 'qnamesize' changed to 'qname_len' for similar naming scheme.
8041 - Acknowledge use of unbound-java code in iterator. Nicer readme.
8042 - services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
8043 rrset cache from module environment.
8044 - packed rrset key has type and class as easily accessible struct
8045 members. They are still kept in network format for fast msg encode.
8046 - dns cache find_delegation routine.
8047 - iterator main functions setup.
8048 - dns cache lookup setup.
8051 - small changes to prepare for subqueries.
8052 - iterator forwarder feature separated out.
8053 - iterator hints stub code, config file stub code, so that first
8054 testing can proceed locally.
8055 - replay tests now have config option to enable forwarding mode.
8058 - outside network does precise timers for roundtrip estimates for rtt
8059 and for setting timeout for UDP. Pending_udp takes milliseconds.
8060 - cleaner iterator sockaddr conversion of forwarder address.
8061 - iterator/iter_utils and iter_delegpt setup.
8065 - outbound query list for modules and support to callback with the
8066 outbound entry to the module.
8067 - testbound support for new serviced queries.
8068 - test for retry to TCP cannot use testbound any longer.

8070 - fixes for no-locking compile.
8071 - mini_event timer precision and fix for change in timeouts during
8072 timeout callback. Fix for fwd_three tests, performed nonexit query.
8075 - small comment on hash table locking.
8076 - outside network serviced queries, contain edns and tcp fallback,
8077 and udp retries and rtt timing.

8125 - EDNS read from query, used to make reply smaller.
8126 - advertised edns value constants.
8127 - EDNS BADVERS response, if asked for too high edns version.
8128 - EDNS extended error responses once the EDNS record from the query
8129 has successfully been parsed.
8132 - msgreply sizefunc is more accurate.
8133 - config settings for rrset cache size and slabs.
8134 - hashtable insert takes argument so that a thread can use its own
8135 alloc cache to store released keys.
8136 - alloc cache special_release() locks if necessary.
8137 - rrset trustworthiness type added.
8138 - thread keeps a scratchpad region for handling messages.

8149 - uses new msgreply format in cache.
8152 - dname unit tests in own file and spread out neatly in functions.
8153 - more dname unit tests.
8154 - message encoding creates truncated TC flagged messages if they do
8155 not fit, and will leave out (whole)rrsets from additional if needed.
8158 - decompress query section, extremely lenient acceptance.
8159 But only for answers from other servers, not for plain queries.
8160 - compression and decompression test cases.
8162 - example.conf interface: line is changed from 127.0.0.1 which leads
8163 to problems if used (restricting communication to the localhost),
8164 to a documentation and test address.
8166 27 April 2007: Wouter

8226 memory size to allocate for rrs.
8227 - code to handle ID creation.
8229 13 April 2007: Wouter

8233 - dname compare routine that preserves case, with unit tests.
8235 11 April 2007: Wouter
8236 - parse work - dname packet parse, msgparse, querysection parse,
8237 start of sectionparse.
8239 10 April 2007: Wouter
8240 - Improved alignment of reply_info packet, nice for 32 and 64 bit.

8271 - check sizes of udp received messages, not too short.
8272 - review changes. Some memmoves can be memcpys: 4byte aligned.
8273 set id correctly on cached answers.
8274 - review changes msgreply.c, memleak on error condition. AA flag
8275 clear on cached reply. Lowercase queries on hashing.
8276 unit test on lowercasing. Test AA bit not set on cached reply.
8277 Note that no TTLs are managed.
8279 29 March 2007: Wouter
8280 - writev or sendmsg used when answering from cache.
8281 This avoids a copy of the data.
8282 - do not do useless byteswap on query id. Store reply flags in uint16
8283 for easier access (and no repeated byteswapping).
8285 - configure detects and config.h includes sys/uio.h for writev decl.
8287 28 March 2007: Wouter
8288 - new config option: num-queries-per-thread.
8289 - added tpkg test for answering three queries at the same time
8290 using one thread (from the query service list).
8292 27 March 2007: Wouter
8293 - added test for cache and not cached answers, in testbound replays.
8294 - testbound can give config file and commandline options from the
8295 replay file to unbound.
8296 - created test that checks if items drop out of the cache.
8297 - added word 'partitioned hash table' to documentation on slab hash.
8298 A slab hash is a partitioned hash table.
8299 - worker can handle multiple queries at a time.
8301 26 March 2007: Wouter
8302 - config settings for slab hash message cache.
8303 - test for cached answer.
8304 - Fixup deleting fake answer from testbound list.
8306 23 March 2007: Wouter
8307 - review of yesterday's commits.
8308 - covered up memory leak of the entry locks.
8309 - answers from the cache correctly. Copies flags correctly.
8310 - sanity check for incoming query replies.
8311 - slabbed hash table. Much nicer contention, need dual cpu to see.
8313 22 March 2007: Wouter
8314 - AIX configure check.
8315 - lock-verify can handle references to locks that are created
8316 in files it has not yet read in.
8317 - threaded hash table test.
8318 - unit test runs lock-verify afterwards and checks result.
8319 - need writelock to update data on hash_insert.
8320 - message cache code, msgreply code.
8322 21 March 2007: Wouter
8323 - unit test of hash table, fixup locking problem in table_grow().
8324 - fixup accounting of sizes for removing items from hashtable.
8325 - unit test for hash table, single threaded test of integrity.
8326 - lock-verify reports errors nicely. More quiet in operation.
8328 16 March 2007: Wouter
8329 - lock-verifier, checks consistent order of locking.
8331 14 March 2007: Wouter
8332 - hash table insert (and subroutines) and lookup implemented.
8333 - hash table remove.
8334 - unit tests for hash internal bin, lru functions.
8336 13 March 2007: Wouter
8337 - lock_unprotect in checklocks.
8338 - util/storage/lruhash.h for LRU hash table structure.
8340 12 March 2007: Wouter
8341 - configure.ac moved to 0.2.
8342 - query_info and replymsg util/data structure.
8344 9 March 2007: Wouter
8345 - added rwlock writelock checking.
8346 So it will keep track of the writelock, and readlocks are enforced
8347 to not change protected memory areas.
8348 - log_hex function to dump hex strings to the logfile.
8349 - checklocks zeroes its destroyed lock after checking memory areas.
8350 - unit test for alloc.
8351 - identifier for union in checklocks to please older compilers.
8354 8 March 2007: Wouter
8355 - Reviewed checklock code.
8357 7 March 2007: Wouter
8358 - created a wrapper around thread calls that performs some basic
8359 checking for data race and deadlock, and basic performance
8360 contention measurement.
8362 6 March 2007: Wouter
8363 - Testbed works with threading (different machines, different options).
8364 - alloc work, does the special type.
8366 2 March 2007: Wouter
8367 - do not compile fork funcs unless needed. Otherwise will give
8368 type errors as their typedefs have not been enabled.
8369 - log shows thread numbers much more nicely (and portably).
8370 - even on systems with nonthreadsafe libevent signal handling,
8371 unbound will exit if given a signal.
8372 Reloads will not work, and exit is not graceful.
8373 - start of alloc framework layout.
8375 1 March 2007: Wouter
8376 - Signals, libevent and threads work well, with libevent patch and
8377 changes to code (close after event_del).
8378 - set ipc pipes nonblocking.
8380 27 February 2007: Wouter
8381 - ub_thread_join portable definition.
8382 - forking is used if no threading is available.
8383 Tested, it works, since pipes work across processes as well.
8384 Thread_join is replaced with waitpid.
8385 - During reloads the daemon will temporarily handle signals,
8386 so that they do not result in problems.
8387 - Also randomize the outgoing port range for tests.
8388 - If query list is full, will stop selecting listening ports for read.
8389 This makes all threads service incoming requests, instead of one.
8390 No memory is leaking during reloads, service of queries, etc.
8391 - test that uses ldns-testns -f to test threading. Have to answer
8392 three queries at the same time.
8393 - with verbose=0 operates quietly.
8395 26 February 2007: Wouter
8396 - ub_random code used to select ID and port.
8397 - log code prints thread id.
8398 - unbound can thread itself, with reload(HUP) and quit working
8400 - don't open pipes for #0, doesn't need it.
8401 - listens to SIGTERM, SIGQUIT, SIGINT (all quit) and SIGHUP (reload).
8403 23 February 2007: Wouter
8404 - Can do reloads on sigHUP. Everything is stopped, and freed,
8405 except the listening ports. Then the config file is reread.
8406 And everything is started again (and listening ports if needed).
8407 - Ports for queries are shared.
8408 - config file added interface:, chroot: and username:.
8409 - config file: directory, logfile, pidfile. And they work too.
8410 - will daemonize by default now. Use -d to stay in the foreground.
8411 - got BSD random[256 state] code, made it threadsafe. util/random.
8413 22 February 2007: Wouter
8414 - Have a config file. Removed commandline options, moved to config.
8415 - tests use config file.
8417 21 February 2007: Wouter
8418 - put -c option in man page.
8419 - minievent fd array capped by FD_SETSIZE.
8421 20 February 2007: Wouter
8422 - Added locks code and pthread spinlock detection.
8423 - can use no locks, or solaris native thread library.
8424 - added yacc and lex configure, and config file parsing code.
8425 also makedist.sh, and manpage.
8426 - put include errno.h in config.h
8428 19 February 2007: Wouter
8429 - Created 0.0 svn tag.
8430 - added acx_pthread.m4 autoconf check for pthreads from
8431 the autoconf archive. It is GPL-with-autoconf-exception Licensed.
8432 You can specify --with-pthreads, or --without-pthreads to configure.
8434 16 February 2007: Wouter
8435 - Updated testbed script, works better by using make on remote end.
8436 - removed check decls, we can compile without them.
8437 - makefile supports LIBOBJ replacements.
8438 - docs checks ignore compat code.
8439 - added util/mini-event.c and .h, a select based alternative used with
8440 ./configure --with-libevent=no
8441 It is limited to 1024 file descriptors, and has less features.
8442 - will not create ip6 sockets if ip6 not on the machine.
8444 15 February 2007: Wouter
8445 - port to FreeBSD 4.11 Dec Alpha. Also works on Solaris 10 sparc64,
8446 Solaris 9, FreeBSD 6, Linux i386 and OSX powerpc.
8447 - malloc rndstate, so that it is aligned for access.
8448 - fixed rbtree cleanup with postorder traverse.
8449 - fixed pending messages are deleted when handled.
8450 - You can control verbosity; default is not verbose, every -v
8451 adds more verbosity.
8453 14 February 2007: Wouter
8454 - Included configure.ac changes from ldns.
8455 - detect (some) headers before the standards check.
8456 - do not use isblank to test c99, since its not available on solaris9.
8457 - review of testcode.
8458 * entries in a RANGE are no longer reversed.
8459 * print name of file with replay entry parse errors.
8460 - port to OSX: cast to int for some prints of sizet.
8461 - Makefile copies ldnstestpkts.c before doing dependencies on it.
8463 13 February 2007: Wouter
8464 - work on fake events, first fwd replay works.
8465 - events can do timeouts and errors on queries to servers.
8466 - test package that runs replay scenarios.

8469 - work on fake events.
8471 9 February 2007: Wouter
8472 - replay file reading.
8473 - fake event setup, it creates fake structures, and teardowns,
8474 added signal callbacks to reply to be able to fake those,
8475 and main structure of event replay routines.
8477 8 February 2007: Wouter
8480 - testcode/fake_event work.
8482 7 February 2007: Wouter
8483 - return answer with the same ID as query was sent with.
8484 - created udp forwarder test. I've done some effort to make it perform
8485 quickly. After servers are created, no big sleep statements but
8486 it checks the logfiles to see if servers have come up. Takes 0.14s.
8487 - set addrlen value when calling recvfrom.
8488 - comparison of addrs more portable.
8489 - LIBEVENT option for testbed to set libevent directory.
8490 - work on tcp input.
