576 11 September 2018: Wouter
577 - Fixed unused return value warnings in contrib/fastrpz.patch for
579 - Fix to squelch respip warning in unit test, it is printed at
580 higher verbosity settings.

607 - Disable minimal-responses in ipsecmod unit tests.
608 - Added serve-expired-ttl and serve-expired-ttl-reset options.
610 27 August 2018: Wouter
611 - Set defaults to yes for a number of options to increase speed and
612 resilience of the server. The so-reuseport, harden-below-nxdomain,
613 and minimal-responses options are enabled by default. They used
614 to be disabled by default, waiting to make sure they worked. They
615 are enabled by default now, and can be disabled explicitly by
616 setting them to "no" in the unbound.conf config file. The reuseport
617 and minimal options increases speed of the server, and should be
618 otherwise harmless. The harden-below-nxdomain option works well
619 together with the recently default enabled qname minimisation, this
620 causes more fetches to use information from the cache.
621 - next release is called 1.8.0.
622 - Fix lintflags for lint on FreeBSD.

644 to the event callback function signature. That needs programs,
645 that use it, to recompile against the new header definition.
646 - print servfail info to log as error.
647 - added more servfail printout statements, to the iterator.

686 This limits the number of simultaneous TCP client connections
687 from a nominated netblock.
688 - make depend, yacc, lex, doc, headers. And log the limit exceeded
689 message only on high verbosity, so as to not spam the logs when

715 - Patches from Jim Hague (Sinodun) for EDNS KeepAlive.
716 - Sort out test runs when the build directory isn't the project

1316 - [dnscrypt] prevent dnscrypt-secret-key, dnscrypt-provider-cert
1318 - [dnscrypt] introduce dnscrypt-provider-cert-rotated option,
1320 This option allows handling multiple cert/key pairs while only
1321 distributing some of them.
1322 In order to reliably match a client magic with a given key without
1323 strong assumption as to how those were generated, we need both key and
1324 cert. Likewise, in order to know which ES version should be used.
1325 On the other hand, when rotating a cert, it can be desirable to only
1326 serve the new cert but still be able to handle clients that are still
1327 using the old certs's public key.
1328 The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not
1329 publish the cert as part of the DNS's provider_name's TXT answer.

2931 - Libunbound skips dos-line-endings from etc/hosts.
2932 - Unbound exits with a fatal error when the auto-trust-anchor-file
2933 fails to be writable. This is seconds after startup. You can
2934 load a readonly auto-trust-anchor-file with trust-anchor-file.
2935 The file has to be writable to notice the trust anchor change,
2936 without it, a trust anchor change will be unnoticed and the system
2937 will then become inoperable.
2938 - unbound-control list_insecure command shows the negative trust
2939 anchors currently configured, patch from Jelte Jansen.

2996 - 0x20 fallback improved: servfail responses do not count as missing
2997 comparisons (except if all responses are errors),
2998 inability to find nameservers does not fail equality comparisons,
2999 many nameservers does not try to compare more than max-sent-count,
3000 parse failures start 0x20 fallback procedure.

3362 fixes from FreeBSD's copy of Unbound, he notes:
3363 Generate unbound-control-setup.sh at build time so it respects
3364 prefix and sysconfdir from the configure script. Also fix the
3365 umask to match the comment, and the comment to match the umask.
3366 Add const and static where needed. Use unions instead of
3367 playing pointer poker. Move declarations that are needed in
3368 multiple source files into a shared header. Move sldns_bgetc()
3369 from parse.c to buffer.c where it belongs. Introduce a new
3370 header file, worker.h, which declares the callbacks that
3371 all workers must define. Remove those declarations from
3372 libworker.h. Include the correct headers in the correct places.
3373 Fix a few dummy callbacks that don't match their prototype.
3374 Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK.
3375 Remove a useless printf which breaks reproducible builds.
3376 Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
3377 no longer used. Add unbound-control-setup.sh to the list of
3378 generated files. The prototype for libworker_event_done_cb()
3379 needs to be moved from libunbound/libworker.h to
3380 libunbound/worker.h.

3484 - iana portlist updated.
3486 20 February 2014: Matthijs
3487 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
3488 received. This is okay according 4035, but not after revising
3489 existence in 4592. NSEC empty non-terminals exist and thus the
3490 RCODE should have been NOERROR. If this occurs, and the RRsets
3491 are secure, we set the RCODE to NOERROR and the security status
3492 of the response is also considered secure.
3494 14 February 2014: Wouter
3495 - Works on Minix (3.2.1).
3497 11 February 2014: Wouter

3527 - fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
3530 30 January 2014: Wouter
3531 - delay-close does not act if there are udp-wait queries, so that
3532 it does not make a socketdrain DoS easier.
3534 28 January 2014: Wouter
3535 - iana portlist updated.
3536 - iana portlist test updated so it does not touch the source
3537 if there are no changes.
3538 - delay-close: msec option that delays closing ports for which
3539 the UDP reply has timed out. Keeps the port open, only accepts
3540 the correct reply. This correct reply is not used, but the port
3541 is open so that no port-denied ICMPs are generated.
3543 27 January 2014: Wouter
3544 - reuseport is attempted, then fallback to without on failure.
3546 24 January 2014: Wouter
3547 - Change unbound-event.h to use void* buffer, length idiom.
3548 - iana portlist updated.
3549 - unbound-event.h is installed if you configure --enable-event-api.
3550 - speed up unbound (reports say it could be up to 10%), by reducing
3551 lock contention on localzones.lock. It is changed to an rwlock.
3552 - so-reuseport: yesno option to distribute queries evenly over
3553 threads on Linux (Thanks Robert Edmonds).
3556 21 January 2014: Wouter
3557 - Fix #547: no trustanchor written if filesystem full, fclose checked.
3559 17 January 2014: Wouter

3581 linking with libldns that uses global variables ldns_ .
3584 - Fix bug#537: compile python plugin without ldns library.
3587 - Fix bug#536: acl_deny_non_local and refuse_non_local added.
3590 - Patch from Neel Goyal to fix async id assignment if callback
3591 is called by libunbound in the mesh attach.

3603 more specific interface port 53 can be used at the same time, and
3604 one of the daemons is unbound.
3605 - iana portlist update.
3606 - separate ldns into core ldns inside ldns/ subdirectory. No more
3607 --with-ldns is needed and unbound does not rely on libldns.
3608 - portability fixes for new USE_SLDNS ldns subdir codebase.
3611 - Patch from Neel Goyal: Add an API call to set an event base on an
3612 existing ub_ctx. This basically just destroys the current worker and
3613 sets the event base to the current. And fix a deadlock in
3614 ub_resolve_event – the cfglock is held when libworker_create is
3615 called. This ends up trying to acquire the lock again in
3616 context_obtain_alloc in the call chain.
3617 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
3620 - unbound-event.h is installed if configured --with-libevent. It
3621 contains low-level library calls, that use libevent's event_base
3622 and an ldns_buffer for the wire return packet to perform async
3623 resolution in the client's eventloop.
3626 - 1.4.21 tag created.

3690 - Fixup manpage syntax.
3693 - get_option and set_option support for log-time-ascii, python-script
3694 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
3695 immediately. The others are mostly useful for libunbound users.
3698 - get_option, set_option, unbound-checkconf -o and libunbound
3699 getoption and setoption support cache-min-ttl and cache-max-ttl.
3702 - Fix#501: forward-first does not recurse, when forward name is ".".
3703 - iana portlist update.
3704 - Max include depth is unlimited.
3707 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply
3708 patch to it to not fail when -Werror is also specified, from the
3710 - iana portlist update.

4093 - fix bug #442: Fix that Makefile depends on pythonmod headers
4094 even using --without-pythonmodule.
4096 22 March 2012: Wouter
4097 - contrib/validation-reporter follows rotated log file (patch from
4100 21 March 2012: Wouter
4101 - new approach to NS fetches for DS lookup that works with
4102 cornercases, and is more robust and considers forwarders.
4104 19 March 2012: Wouter
4105 - iana portlist updated.
4106 - fix to locate nameservers for DS lookup with NS fetches.
4108 16 March 2012: Wouter
4109 - Patch for access to full DNS packet data in unbound python module
4112 9 March 2012: Wouter
4113 - Applied line-buffer patch from Augie Schwer to validation.reporter.sh.
4115 2 March 2012: Wouter
4116 - flush_infra cleans timeouted servers from the cache too.
4117 - removed warning from --enable-ecdsa.
4119 1 March 2012: Wouter
4120 - forward-first option. Tries without forward if a query fails.
4121 Also stub-first option that is similar.
4123 28 February 2012: Wouter
4124 - Fix from code review, if EINPROGRESS not defined chain if statement
4127 27 February 2012: Wouter

4129 for unbound-control.exe, and unbound-checkconf.exe.
4131 23 February 2012: Wouter
4132 - Fix to squelch 'network unreachable' errors from tcp connect in
4133 logs, high verbosity will show them.
4135 16 February 2012: Wouter
4136 - iter_hints is now thread-owned in module env, and thus threadsafe.
4137 - Fix prefetch and sticky NS, now the prefetch works. It picks
4138 nameservers that 'would be valid in the future', and if this makes
4139 the NS timeout, it updates that NS by asking delegation from the
4140 parent again. If child NS has longer TTL, that TTL does not get
4141 refreshed from the lookup to the child nameserver.
4143 15 February 2012: Wouter
4144 - Fix forward-zone memory, uses malloc and frees original root dp.
4145 - iter hints (stubs) uses malloc inside for more dynamicity.
4146 - unbound-control forward_add, forward_remove, stub_add, stub_remove
4147 can modify stubs and forwards for running unbound (on mobile computer)
4148 they can also add and remove domain-insecure for the zone.
4150 14 February 2012: Wouter
4151 - Fix sticky NS (ghost domain problem) if prefetch is yes.
4152 - iter forwards uses malloc inside for more dynamicity.
4154 13 February 2012: Wouter
4155 - RT#2955. Fix for cygwin compilation.
4156 - iana portlist updated.
4158 10 February 2012: Wouter
4159 - Slightly smaller critical region in one case in infra cache.
4160 - Fix timeouts to keep track of query type, A, AAAA and other, if
4161 another has caused timeout blacklist, different type can still probe.
4162 - unit test fix for nomem_cnametopos.rpl race condition.
4164 9 February 2012: Wouter
4165 - Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
4167 8 February 2012: Wouter
4168 - implement draft-ietf-dnsext-ecdsa-04; which is in IETF LC; This
4169 implementation is experimental at this time and not recommended
4170 for use on the public internet (the protocol numbers have not
4171 been assigned). Needs recent ldns with --enable-ecdsa.
4172 - fix memory leak in errorcase for DSA signatures.
4173 - iana portlist updated.
4174 - workaround for openssl 0.9.8 ecdsa sha2 and evp problem.
4176 3 February 2012: Wouter

4181 - svn trunk is 1.4.17 in development.
4182 - iana portlist updated.
4184 1 February 2012: Wouter
4185 - Fix validation failures (like: validation failure xx: no NSEC3
4186 closest encloser from yy for DS zz. while building chain of trust,
4187 because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
4188 for an NSEC3. Now it does not change rdata, and fixes TTL.
4190 30 January 2012: Wouter
4191 - Fix version-number in libtool to be version-info so it produces
4192 libunbound.so.2 like it should.
4194 26 January 2012: Wouter
4195 - Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.

4200 23 January 2012: Wouter
4201 - Fix memset in test code.
4203 20 January 2012: Wouter
4204 - Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
4206 19 January 2012: Wouter
4207 - Fix to write key files completely to a temporary file, and if that
4208 succeeds, replace the real key file. So failures leave a useful file.
4210 18 January 2012: Wouter
4211 - tag 1.4.15rc1 created
4212 - updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
4214 17 January 2012: Wouter
4215 - Fix bug where canonical_compare of RRSIG did not downcase the
4216 signer-name. This is mostly harmless because RRSIGs do not have
4217 to be sorted in canonical order, usually.
4219 12 January 2012: Wouter
4220 - bug#428: add ub_version() call to libunbound. API version increase,
4221 with (binary) backwards compatibility for the previous version.
4223 10 January 2012: Wouter
4224 - Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
4225 that would be permissible by the RFCs but it is not the TTL in the
4227 - iana portlist updated.
4228 - uninitialised variable in reprobe for rtt blocked domains fixed.
4229 - lintfix and new flex output.
4231 2 January 2012: Wouter
4232 - Fix to randomize hash function, based on 28c3 congress, reported
4235 24 December 2011: Wouter
4236 - Fix for memory leak (about 20 bytes when a tcp or udp send operation
4237 towards authority servers failed, takes about 50.000 such failures to
4238 leak one Mb, such failures are also usually logged), reported by
4240 - iana portlist updated.
4242 19 December 2011: Wouter
4243 - Fix for VU#209659 CVE-2011-4528: Unbound denial of service
4244 vulnerabilities from nonstandard redirection and denial of existence
4245 http://www.unbound.net/downloads/CVE-2011-4528.txt

4273 28 November 2011: Wouter
4274 - Fix quartile time estimate, it was too low, (thanks Jan Komissar).
4275 - iana ports updated.

4296 - documentation for new options: ssl-upstream, ssl-service-key and
4298 - iana portlist updated.
4299 - fix -flto detection on Lion for llvm-gcc.

4302 - dns over ssl support, ssl-service-pem and ssl-service-key files
4303 can be given and then TCP queries are serviced wrapped in SSL.
4305 27 October 2011: Wouter
4306 - lame-ttl and lame-size options no longer exist, it is integrated
4307 with the host info. They are ignored (with verbose warning) if
4308 encountered to keep the config file backwards compatible.

4310 - fix export-all-symbols on OSX.
4312 26 October 2011: Wouter

4318 24 October 2011: Wouter
4319 - Fix resolve of partners.extranet.microsoft.com with a fix for the
4320 server selection for choosing out of a (particular) list of bad
4322 - Fix make_new_space function so that the incoming query is not
4323 overwritten if a jostled out query causes a waiting query to be
4324 resumed that then fails and sends an error message. (Thanks to
4327 21 October 2011: Wouter
4328 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
4329 option enabled because of memory layout exe vs dll.
4331 19 October 2011: Wouter
4332 - fix unbound-anchor for broken strptime on OSX lion, detected
4334 - Detect if GOST really works, openssl1.0 on OSX fails.
4335 - Implement ipv6%interface notation for scope_id usage.
4337 17 October 2011: Wouter
4338 - better documentation for inform_super (Thanks Yang Zhe).
4340 14 October 2011: Wouter
4341 - Fix for out-of-memory condition in libunbound (thanks
4344 13 October 2011: Wouter
4345 - Fix --enable-allsymbols, it depended on link specifics of the
4346 target platform, or fptr_wlist assertion failures could occur.
4348 12 October 2011: Wouter
4349 - updated contrib/unbound_munin_ to family=auto so that it works with
4350 munin-node-configure automatically (if installed as
4351 /usr/local/share/munin/plugins/unbound_munin_ ).
4353 27 September 2011: Wouter
4354 - unbound.exe -w windows option for start and stop service.
4356 23 September 2011: Wouter
4357 - TCP-upstream calculates tcp-ping so server selection works if there
4360 20 September 2011: Wouter
4361 - Fix classification of NS set in answer section, where there is a
4362 parent-child server, and the answer has the AA flag for dir.slb.com.
4363 Thanks to Amanda Constant from Secure64.
4365 16 September 2011: Wouter
4366 - fix bug #408: accept patch from Steve Snyder that comments out
4367 unused functions in lookup3.c.
4368 - iana portlist updated.
4369 - fix EDNS1480 change memleak and TCP fallback.
4370 - fix various compiler warnings (reported by Paul Wouters).
4371 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
4372 fetch if sentcount > 3, stop query if sentcount > 16. Count is
4373 reset when referral or CNAME happens. This makes unbound better
4374 at managing large NS sets, they are explored when there is continued
4375 interest (in the form of queries).
4377 15 September 2011: Wouter
4379 - trunk contains 1.4.14 in development.
4380 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
4382 12 September 2011: Wouter
4383 - Reverted dns EDNS backoff fix, it did not help and needs
4384 fragmentation fixes instead.
4387 7 September 2011: Wouter
4388 - Fix operation in ipv6 only (do-ip4: no) mode.
4390 6 September 2011: Wouter
4391 - fedora specfile updated.
4393 5 September 2011: Wouter
4396 2 September 2011: Wouter
4397 - iana portlist updated.
4399 26 August 2011: Wouter
4400 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
4401 - Fix validation failures due to EDNS backoff retries, the retry
4402 for fetch of data has want_dnssec because the iter_indicate_dnssec
4403 function returns true when validation failure retry happens, and
4404 then the serviced query code does not fallback to noEDNS, even if
4405 the cache says it has this. This helps for DLV deployment when
4406 the DNSSEC status is not known for sure before the lookup concludes.
4408 24 August 2011: Wouter
4409 - Applied patch from Karel Slany that fixes a memory leak in the
4410 unbound python module, in string conversions.
4412 22 August 2011: Wouter
4413 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
4414 Zhang and Luo Ce). Unbound responds with the RR types that are
4415 available at the name for qtype ANY and validates those RR types.
4416 It does not test for completeness (i.e. with NSEC or NSEC3 query),
4417 and it does not follow the CNAME or DNAME to another name (with
4418 even more data for the already large response).
4419 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
4420 - Documented the options that work with control set_option command.
4421 - tcp-upstream yes/no option (works with set_option) for tunnels.
4423 18 August 2011: Wouter
4424 - fix autoconf call in makedist crosscompile to RC or snapshot.
4426 17 August 2011: Wouter

4442 1 August 2011: Wouter
4443 - Fix autoconf 2.68 warnings
4445 14 July 2011: Wouter
4446 - Unbound implements RFC6303 (since version 1.4.7).
4447 - tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the

4451 13 July 2011: Wouter
4452 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
4454 11 July 2011: Wouter
4455 - Fix wildcard expansion no-data reply under an optout NSEC3 zone is
4456 validated as insecure, reported by Jia Li (lijia@cnnic.cn).
4459 - 1.4.12rc1 tag created.
4462 - version number in example config file.
4463 - fix that --enable-static-exe does not complain about it unknown.
4465 30 June 2011: Wouter
4466 - tag relase 1.4.11, trunk is 1.4.12 development.
4467 - iana portlist updated.
4468 - fix bug#395: id bits of other query may leak out under conditions
4469 - fix replyaddr count wrong after jostled queries, which leads to
4470 eventual starvation where the daemon has no replyaddrs left to use.
4471 - fix comment about rndc port, that referred to the old port number.
4472 - fix that the listening socket is not closed when too many remote
4473 control connections are made at the same time.
4474 - removed ldns-src tarball inside the unbound tarball.
4476 23 June 2011: Wouter
4477 - Changed -flto check to support clang compiler.
4478 - tag 1.4.11rc3 created.
4480 17 June 2011: Wouter
4481 - tag 1.4.11rc1 created.
4482 - remove warning about signed/unsigned from flex (other flex version).
4483 - updated aclocal.m4 and libtool to match.
4484 - tag 1.4.11rc2 created.
4486 16 June 2011: Wouter
4487 - log-queries: yesno option, default is no, prints querylog.
4488 - version is 1.4.11.
4490 14 June 2011: Wouter
4491 - Use -flto compiler flag for link time optimization, if supported.
4492 - iana portlist updated.
4494 12 June 2011: Wouter
4495 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
4497 10 June 2011: Wouter
4498 - unbound-control has version number in the header,
4499 UBCT[version]_space_ is the header sent by the client now.
4500 - Unbound control port number is registered with IANA:
4501 ub-dns-control 8953/tcp unbound dns nameserver control
4502 This is the new default for the control-port config setting.
4503 - statistics-interval prints the number of jostled queries to log.
4506 - Fix Makefile for U in environment, since wrong U is more common than
4507 deansification necessity.
4508 - iana portlist updated.
4509 - updated ldns tarball to 1.6.10rc2 snapshot of today.
4512 - Fix assertion failure when unbound generates an empty error reply
4513 in response to a query, CVE-2011-1922 VU#531342.
4514 - This fix is in tag 1.4.10.
4515 - defense in depth against the above bug, an error is printed to log
4516 instead of an assertion failure.
4519 - bug#386: --enable-allsymbols option links all binaries to libunbound
4520 and reduces install size significantly.
4521 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
4522 - iana portlist updated.
4523 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
4525 14 April 2011: Wouter
4526 - configure created with newer autoconf 2.66.
4528 12 April 2011: Wouter
4529 - bug#378: Fix that configure checks for ldns_get_random presence.
4531 8 April 2011: Wouter
4532 - iana portlist updated.
4533 - queries with CD flag set cause DNSSEC validation, but the answer is
4534 not withheld if it is bogus. Thus, unbound will retry if it is bad
4535 and curb the TTL if it is bad, thus protecting the cache for use by
4536 downstream validators.
4537 - val-override-date: -1 ignores dates entirely, for NTP usage.
4539 29 March 2011: Wouter
4540 - harden-below-nxdomain: changed so that it activates when the
4541 cached nxdomain is dnssec secure. This avoids backwards
4542 incompatibility because those old servers do not have dnssec.
4544 24 March 2011: Wouter
4545 - iana portlist updated.
4549 17 March 2011: Wouter
4550 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.

4561 - give config parse error for multiple names on a stub or forward zone.
4562 - updated ldns tarball to 1.6.9(todays snapshot).
4564 24 February 2011: Wouter
4565 - bug #361: Fix, time.elapsed variable not reset with stats_noreset.

4577 and under the terms of our LICENSE (see that file in the source).
4579 11 February 2011: Wouter
4580 - iana portlist updated.
4581 - tpkg updated with common.sh for common functionality.
4583 7 February 2011: Wouter

4601 17 January 2011: Wouter
4602 - add get and set option for harden-below-nxdomain feature.
4603 - iana portlist updated.
4605 14 January 2011: Wouter
4606 - Fix so a changed NS RRset does not get moved name stuck on old
4607 server, for type NS the TTL is not increased.
4609 13 January 2011: Wouter
4610 - Fix prefetch so it does not get stuck on old server for moved names.
4612 12 January 2011: Wouter

4624 - iana portlist updated.
4626 23 December 2010: Wouter
4627 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
4629 21 December 2010: Wouter
4630 - algorithm compromise protection using the algorithms signalled in
4631 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
4632 and thus, if you have multiple algorithms in your trust-anchor-file
4633 then it will now behave different than before. Also, 5011 rollover
4634 for algorithms needs to be double-signature until the old algorithm
4636 It is not an option, because I see no use to turn the security off.
4637 - iana portlist updated.
4639 17 December 2010: Wouter
4640 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
4641 - fix validation in this case: CNAME to nodata for co-hosted opt-in
4642 NSEC3 insecure delegation, was bogus, fixed to be insecure.
4644 16 December 2010: Wouter
4645 - Fix our 'BDS' license (typo reported by Xavier Belanger).
4647 10 December 2010: Wouter

4659 - iana portlist updated.
4661 18 November 2010: Wouter
4662 - harden-below-nxdomain option, default off (because very old
4663 software may be incompatible). We could enable it by default in
4666 17 November 2010: Wouter
4667 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
4668 - make test output nicer.
4670 15 November 2010: Wouter
4671 - silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
4672 - iana portlist updated.
4673 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
4675 9 November 2010: Wouter
4676 - unbound-anchor compiles with openssl 0.9.7.
4678 8 November 2010: Wouter
4679 - release tag 1.4.7.

4681 - Be lenient and accept imgw.pl malformed packet (like BIND).
4683 5 November 2010: Wouter
4684 - do not synthesize a CNAME message from cache for qtype DS.
4686 4 November 2010: Wouter
4687 - Use central entropy to seed threads.
4689 3 November 2010: Wouter
4690 - Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
4692 2 November 2010: Wouter
4696 1 November 2010: Wouter
4697 - GOST code enabled by default (RFC 5933).
4699 27 October 2010: Wouter
4700 - Fix uninit value in dump_infra print.
4701 - Fix validation failure for parent and child on same server with an
4702 insecure childzone and a CNAME from parent to child.
4703 - Configure detects libev-4.00.
4705 26 October 2010: Wouter
4706 - dump_infra and flush_infra commands for unbound-control.
4707 - no timeout backoff if meanwhile a query succeeded.
4708 - Change of timeout code. No more lost and backoff in blockage.
4709 At 12sec timeout (and at least 2x lost before) one probe per IP
4710 is allowed only. At 120sec, the IP is blocked. After 15min, a
4711 120sec entry has a single retry packet.
4713 25 October 2010: Wouter
4714 - Configure errors if ldns is not found.
4716 22 October 2010: Wouter
4717 - Windows 7 fix for the installer.
4719 21 October 2010: Wouter
4720 - Fix bug where fallback_tcp causes wrong roundtrip and edns
4721 observation to be noted in cache. Fix bug where EDNSprobe halted
4722 exponential backoff if EDNS status unknown.
4723 - new unresponsive host method, exponentially increasing block backoff.
4724 - iana portlist updated.
4726 20 October 2010: Wouter
4727 - interface automatic works for some people with ip6 disabled.
4728 Therefore the error check is removed, so they can use the option.
4730 19 October 2010: Wouter
4731 - Fix for request list growth, if a server has long timeout but the
4732 lost counter is low, then its effective rtt is the one without
4733 exponential backoff applied. Because the backoff is not working.
4734 The lost counter can then increase and the server is blacklisted,
4735 or the lost counter does not increase and the server is working
4738 18 October 2010: Wouter
4739 - iana portlist updated.
4741 13 October 2010: Wouter
4742 - Fix TCP so it uses a random outgoing-interface.
4743 - unbound-anchor handles ADDPEND keystate.
4745 11 October 2010: Wouter
4746 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
4747 the zone has a secure delegation hosted on the same server did not
4748 verify as secure (it was insecure by mistake).
4749 - iana portlist updated.
4750 - ldns tarball updated (for reading cachedumps with bad RR data).
4752 1 October 2010: Wouter
4753 - test for unbound-anchor. fix for reading certs.
4754 - Fix alloc_reg_release for longer uptime in out of memory conditions.
4756 28 September 2010: Wouter
4757 - unbound-anchor working, it creates or updates a root.key file.
4758 Use it before you start the validator (e.g. at system boot time).
4760 27 September 2010: Wouter
4761 - iana portlist updated.
4763 24 September 2010: Wouter
4764 - bug#329: in example.conf show correct ipv4 link-local 169.254/16.
4766 23 September 2010: Wouter
4767 - unbound-anchor app, unbound requires libexpat (xml parser library).
4769 22 September 2010: Wouter
4770 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
4771 reverse ipv6 orchid prefix from builtin list.
4772 - iana portlist updated.
4774 17 September 2010: Wouter
4775 - DLV has downgrade protection again, because the RFC says so.
4776 - iana portlist updated.
4778 16 September 2010: Wouter
4779 - Algorithm rollover operational reality intrudes, for trust-anchor,
4780 5011-store, and DLV-anchor if one key matches it's good enough.
4781 - iana portlist updated.
4782 - Fix reported validation error in out of memory condition.
4784 15 September 2010: Wouter
4785 - Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
4787 14 September 2010: Wouter
4788 - increased mesh-max-activation from 1000 to 3000 for crazy domains
4789 like _tcp.slb.com with 262 servers.
4790 - iana portlist updated.
4792 13 September 2010: Wouter
4793 - bug#327: Fix for cannot access stub zones until the root is primed.
4795 9 September 2010: Wouter
4796 - unresponsive servers are not completely blacklisted (because of
4797 firewalls), but also not probed all the time (because of the request
4798 list size it generates). The probe rate is 1%.
4799 - iana portlist updated.
4801 20 August 2010: Wouter
4802 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
4803 iterator get_mem includes priv_get_mem. delegpt nodup removed.
4804 listen_pushback, query_info_allocqname, write_socket, send_packet,
4805 comm_point_set_cb_arg and listen_resume removed.
4807 19 August 2010: Wouter
4808 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
4809 Delegpt structures checked for duplicates always.
4810 No more nameserver lookups generated when depth is full anyway.
4811 - example.conf notes how to do DNSSEC validation and track the root.
4812 - iana portlist updated.
4814 18 August 2010: Wouter
4815 - Fix bug#322: configure does not respect CFLAGS on Solaris.
4816 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
4817 if use sun-cc, but some systems need different flags.
4819 16 August 2010: Wouter
4820 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
4821 changes, uses m4_bpatsubst now.
4822 - make test (or make check) should be more portable and run the unit
4823 test and testbound scripts. (make longtest has special requirements).
4825 13 August 2010: Wouter
4826 - More pleasant remote control command parsing.
4827 - documentation added for return values reported by doxygen 1.7.1.
4828 - iana portlist updated.
4830 9 August 2010: Wouter

4852 14 July 2010: Wouter
4853 - Donation text added to README.
4854 - Fix integer underflow in prefetch ttl creation from cache. This
4855 fixes a potential negative prefetch ttl.
4857 12 July 2010: Wouter
4858 - Changed the defaults for num-queries-per-thread/outgoing-range.
4859 For builtin-select: 512/960, for libevent 1024/4096 and for
4860 windows 24/48 (because of win api). This makes the ratio this way
4861 to improve resilience under heavy load. For high performance, use
4862 libevent and possibly higher numbers.
4864 10 July 2010: Wouter
4865 - GOST enabled if SSL is recent and ldns has GOST enabled too.
4866 - ldns tarball updated.
4869 - iana portlist updated.
4870 - Fix validation of qtype DNSKEY when a key-cache entry exists but
4871 no rr-cache entry is used (it expired or prefetch), it then goes
4872 back up to the DS or trust-anchor to validate the DNSKEY.
4875 - Neat function prototypes, unshadowed local declarations.
4878 - failure to chown the pidfile is not fatal any more.
4879 - testbound uses UTC timezone.
4880 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
4881 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
4884 - log if a server is skipped because it is on the donotquery list,
4885 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
4886 - added feature to print configure date, target and options with -h.
4887 - added feature to print event backend system details with -h.
4888 - wdiff is not actually required by make test, updated requirements.
4891 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
4892 must be signed with all algorithms from the DS rrset at the parent.
4893 This is now checked and becomes bogus if not.
4895 28 June 2010: Wouter
4896 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
4897 in overload situations to be about 5 qps for the class of shortly
4899 The capacity of the resolver is then about (numqueriesperthread / 2)
4900 / (average time for such long queries) qps for long queries.
4901 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
4902 qps for short queries, per thread.
4903 - Fix the max number of reply-address count to be applied for duplicate
4904 queries, and not for new query list entries. This raises the memory
4905 usage to a max of (16+1)*numqueriesperthread reply addresses.
4907 25 June 2010: Wouter
4908 - Fix handling of corner case reply from lame server, follows rfc2308.
4909 It could lead to a nodata reply getting into the cache if the search
4910 for a non-lame server turned up other misconfigured servers.
4911 - unbound.h has extern "C" statement for easier include in c++.
4913 23 June 2010: Wouter
4914 - iana portlist updated.
4915 - makedist upgraded cross compile openssl option, like this:
4916 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
4918 22 June 2010: Wouter
4919 - Unbound reports libev or libevent correctly in logs in verbose mode.
4920 - Fix to unload gost dynamic library module for leak testing.
4922 18 June 2010: Wouter
4923 - iana portlist updated.
4925 17 June 2010: Wouter
4926 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
4928 16 June 2010: Wouter
4929 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
4930 assertion was wrong.
4931 - updated ldns tarball.
4933 15 June 2010: Wouter
4934 - tag 1.4.5 created.
4935 - trunk contains 1.4.6 in development.
4936 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
4937 - Fix to use one pointer less for iterator query state store_parent_NS.
4938 - makedist crosscompile to windows uses builtin ldns not host ldns.
4939 - Max referral count from 30 to 130, because 128 one character domains
4941 - added documentation for the histogram printout to syslog.
4943 11 June 2010: Wouter
4944 - When retry to parent the retrycount is not wiped, so failed
4945 nameservers are not tried again.
4946 - iana portlist updated.
4948 10 June 2010: Wouter
4949 - Fix bug where a long loop could be entered, now cycle detection
4950 has a loop-counter and maximum search amount.
4953 - iana portlist updated.
4954 - 1.4.5rc1 tag created.
4957 - ldns tarball updated, 1.6.5.
4958 - review comments, split dependency cycle tracking for parentside
4959 last resort lookups for A and AAAA so there are more lookup options.
4962 - Fix compile warning if compiled without threads.
4963 - updated ldns-tarball with current ldns svn (pre 1.6.5).
4964 - GOST disabled-by-default, the algorithm number is allocated but the
4965 RFC is still has to pass AUTH48 at the IETF.
4968 - Ignore Z flag in incoming messages too.
4969 - Fix storage of negative parent glue if that last resort fails.
4970 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
4971 - new splint flags for newer splint install.
4974 - Fix AD flag handling, it could in some cases mistakenly copy the AD
4975 flag from upstream servers.
4976 - alloc_special_obtain out of memory is not a fatal error any more,
4977 enabling unbound to continue longer in out of memory conditions.
4978 - parentside names are dispreferred but not said to be dnssec-lame.
4979 - parentside check for cached newname glue.
4980 - fix parentside and querytargets modulestate, for dump_requestlist.
4981 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
4982 - fix parentside from cache to be marked dispreferred for bad names.
4985 - iana portlist updated.
4986 - parent-child disagreement approach altered. Older fixes are
4987 removed in place of a more exhaustive search for misconfigured data
4988 available via the parent of a delegation.
4989 This is designed to be throttled by cache entries, with TTL from the
4990 parent if possible. Additionally the loop-counter is used.
4991 It also tests for NS RRset differences between parent and child.
4992 The fetch of misconfigured data should be more reliable and thorough.
4993 It should work reliably even with no or only partial data in cache.
4994 Data received from the child (as always) is deemed more
4995 authoritative than information received from the delegation parent.
4996 The search for misconfigured data is not performed normally.
4999 - Contribution from Migiel de Vos (Surfnet): nagios patch for
5000 unbound-host, in contrib/ (in the source tarball). Makes
5001 unbound-host suitable for monitoring dnssec(-chain) status.
5004 - EDNS timeout code will not fire if EDNS status already known.
5005 - EDNS failure not stored if EDNS status known to work.
5008 - Fix resolution for domains like safesvc.com.cn. If the iterator
5009 can not recurse further and it finds the delegation in a state
5010 where it would otherwise have rejected it outhand if so received
5011 from a cache lookup, then it can try to ask higherup (with loop
5013 - Fix comments in iter_utils:dp_is_useless.
5016 - Fix various compiler warnings from the clang llvm compiler.
5017 - iana portlist updated.
5020 - Fix bug#308: spelling error in variable name in parser and lexer.
5023 - Fix dnssec-missing detection that was turned off by server selection.
5024 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
5025 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
5026 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
5028 29 April 2010: Wouter
5029 - Fix for dnssec lameness detection to use the key cache.
5030 - infra cache entries that are expired are wiped clean. Previously
5031 it was possible to not expire host data (if accessed often).
5033 28 April 2010: Wouter
5034 - ldns tarball updated and GOST support is detected and then enabled.
5035 - iana portlist updated.
5036 - Fix detection of gost support in ldns (reported by Chris Smith).
5038 27 April 2010: Wouter
5039 - unbound-control get_option domain-insecure shows config file items.
5040 - fix retry sequence if prime hints are recursion-lame.
5041 - autotrust anchor file can be initialized with a ZSK key as well.
5042 - harden-referral-path does not result in failures due to max-depth.
5043 You can increase the max-depth by adding numbers (' 0') after the
5044 target-fetch-policy, this increases the depth to which is checked.
5046 26 April 2010: Wouter
5047 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
5048 CPPFLAGS during configure process.
5049 - if libev is installed on the base system (not libevent), detect
5050 it from the event.h header file and link with -lev.
5051 - configlexer.lex gets config.h, and configyyrename.h added by make,
5052 no more double include.
5053 - More strict scrubber (Thanks to George Barwood for the idea):
5054 NS set must be pertinent to the query (qname subdomain nsname).
5055 - Fix bug#307: In 0x20 backoff fix fallback so the number of
5056 outstanding queries does not become -1 and block the request.
5057 Fixed handling of recursion-lame in combination with 0x20 fallback.
5058 Fix so RRsets are compared canonicalized and sorted if the immediate
5059 comparison fails, this makes it work around round-robin sites.
5061 23 April 2010: Wouter
5062 - Squelch log message: sendto failed permission denied for
5063 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
5064 - Fix to fetch data as last resort more tenaciously. When cycle
5065 targets cause the server selection to believe there are more options
5066 when they really are not there, the server selection is reinitiated.
5067 - Fix fetch from blacklisted dnssec lame servers as last resort. The
5068 server's IP address is then given in validator errors as well.
5069 - Fix local-zone type redirect that did not use the query name for
5072 22 April 2010: Wouter
5074 - trunk contains 1.4.5 in development.
5075 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
5076 The validator error message was 'no signatures from ...'.
5078 16 April 2010: Wouter
5079 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
5082 15 April 2010: Wouter
5083 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
5084 example key and signatures for GOST. GOST requires openssl-1.0.0.
5085 GOST is still disabled by default.
5087 9 April 2010: Wouter
5088 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
5089 get into an endless loop, if 0x20 was enabled, and buffers are small
5090 or particular broken packets are received.
5091 - Fix chain of trust with CNAME at an intermediate step, for the DS
5094 8 April 2010: Wouter
5095 - Fix validation of queries with wildcard names (*.example).
5097 6 April 2010: Wouter
5098 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
5099 cache timeout coincided with a server update, the current EDNS
5100 backoff is less sensitive, and does not cache the backoff unless
5101 the backoff actually works and the domain is not expecting DNSSEC.
5102 - GOST support with correct algorithm numbers.
5104 1 April 2010: Wouter
5105 - iana portlist updated.
5107 24 March 2010: Wouter
5108 - unbound control flushed items are not counted when flushed again.
5110 23 March 2010: Wouter
5111 - iana portlist updated.
5113 22 March 2010: Wouter
5114 - unbound-host disables use-syslog from config file so that the
5115 config file for the main server can be used more easily.
5116 - fix bug#301: unbound-checkconf could not parse interface
5117 '0.0.0.0@5353', even though unbound itself worked fine.
5119 19 March 2010: Wouter
5120 - fix fwd_ancil test to pass if the socket options are not supported.
5122 18 March 2010: Wouter
5123 - Fixed random numbers for port, interface and server selection.
5124 Removed very small bias.
5125 - Refer to the listing in unbound-control man page in the extended
5126 statistics entry in the unbound.conf man page.
5128 16 March 2010: Wouter
5129 - Fix interface-automatic for OpenBSD: msg.controllen was too small,
5130 also assertions on ancillary data buffer.
5131 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
5132 - for NSEC3 check if signatures are cached.
5134 15 March 2010: Wouter
5135 - unit test for util/regional.c.
5137 12 March 2010: Wouter
5138 - Reordered configure checks so fork and -lnsl -lsocket checks are
5139 earlier, and thus later checks benefit from and do not hinder them.
5140 - iana portlist updated.
5141 - ldns tarball updated.
5142 - Fix python use when multithreaded.
5143 - Fix solaris python compile.
5144 - Include less in config.h and include per code file for ldns, ssl.

5194 - Also delete potential poison references from additional.
5195 - Fix: no classification of a forwarder as lame, throw away instead.
5197 23 February 2010: Wouter
5198 - libunbound ub_ctx_get_option() added.
5199 - unbound-control set_option and get_option commands.
5200 - iana portlist updated.
5202 18 February 2010: Wouter
5203 - A little more strict DS scrubbing.
5204 - No more blacklisting of unresponsive servers, a 2 minute timeout

5217 16 February 2010: Wouter
5218 - Check for 'no space left on device' (or other errors) when
5219 writing updated autotrust anchors and print errno to log.
5221 15 February 2010: Wouter
5222 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
5223 hardcoded. We made the choice to send out more conservatively,
5224 protecting against an aggregate effect more than protecting a
5225 single user (from their own folly, perhaps in case of misconfig).
5227 12 February 2010: Wouter
5228 - Re-query pattern changed on validation failure. To protect troubled
5229 authority servers, unbound caches a failure for the DNSKEY or DS
5230 records for the entire zone, and only retries that 900 seconds later.
5231 This implies that only a handful of packets are sent extra to the
5232 authority if the zone fails.
5234 11 February 2010: Wouter
5235 - ldns tarball update for long label length syntax error fix.
5236 - iana portlist updated.

5263 - Fixup ldns detection to also check for header files.
5265 13 January 2010: Wouter
5266 - prefetch-key option that performs DNSKEY queries earlier in the
5267 validation process, and that could halve the latency on DNSSEC
5268 queries. It takes some extra processing (CPU, a cache is needed).
5270 12 January 2010: Wouter
5271 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
5273 8 January 2010: Wouter
5274 - Fix for parent-child disagreement code which could have trouble
5275 when (a) ipv6 was disabled and (b) the TTL for parent and child
5276 were different. There were two bugs, the parent-side information
5277 is fixed to no longer block lookup of child side information and
5278 the iterator is fixed to no longer attempt to get ipv6 when it is
5279 not enabled and then give up in failure.
5280 - test and fixes to make prefetch actually store the answer in the
5281 cache. Considers some rrsets 'already expired' but does not allow
5282 overwriting of rrsets considered more secure.
5284 7 January 2010: Wouter
5285 - Fixup python documentation (thanks Leo Vandewoestijne).
5286 - Work on cache prefetch feature.

5322 9 December 2009: Wouter
5323 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
5324 errors generated for domain names like '.example.com'.
5325 - Fix SOA excluded from negative DS responses. Reported by Hauke
5326 Lampe. The negative cache did not include proper SOA records for
5327 negative qtype DS responses which makes BIND barf on it, such
5328 responses are now only used internally.
5329 - Fix negative cache lookup of closestencloser check of DS type bit.
5331 8 December 2009: Wouter
5332 - Fix for lookup of parent-child disagreement domains, where the
5333 parent-side glue works but it does not provide proper NS, A or AAAA
5334 for itself, fixing domains such as motorcaravanners.eu.
5335 - Feature: you can specify a port number in the interface: line, so
5336 you can bind the same interface multiple times at different ports.
5338 7 December 2009: Wouter
5339 - Bug#287: Fix segfault when unbound-control remove nonexistent local
5340 data. Added check to tests.
5342 1 December 2009: Wouter

5357 - Patch from David Hubbard for libunbound manual page.
5358 - Fixup endless spinning in unbound-control stats reported by

5421 - iana portlist updated.
5423 8 October 2009: Wouter
5425 - add val-log-level print to corner case (nameserver.epost.bg).
5426 - more detail to errors from insecure delegation checks.
5427 - Fix double time subtraction in negative cache reported by
5428 Amanda Constant and Hugh Mahon.
5429 - Made new validator error string available from libunbound for
5430 applications. It is in result->why_bogus, a zero-terminated string.
5431 unbound-host prints it by default if a result is bogus.
5432 Also the errinf is public in module_qstate (for other modules).
5434 7 October 2009: Wouter
5435 - retry for validation failure in DS and prime results. Less mem use.

5444 the NSEC3 patch from the entry above.
5445 - val-log-level: 2 shows extended error information for validation
5446 failures, but still one (longish) line per failure. For example:
5447 validation failure <example.com. DNSKEY IN>: signature expired from
5448 192.0.2.4 for trust anchor example.com. while building chain of trust
5449 validation failure <www.example.com. A IN>: no signatures from
5450 192.0.2.6 for key example.com. while building chain of trust
5452 6 October 2009: Wouter
5453 - Test set updated to provide additional ns lookup result.
5454 The retry would attempt to fetch the data from other nameservers
5455 for bogus data, and this needed to be provisioned in the tests.
5457 5 October 2009: Wouter
5458 - first validation failure retry code. Retries for data failures.
5461 2 October 2009: Wouter

5480 - 5011 probe failure handling fixup.
5481 - test unbound reading of original autotrust data.
5482 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
5483 picked up, otherwise performs initial probe like usual.
5485 22 September 2009: Wouter
5486 - autotrust test with algorithm rollover, new ordering of checks
5487 assists in orderly rollover.
5488 - autotrust test with algorithm rollover to unknown algorithm.

5492 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
5494 18 September 2009: Wouter
5495 - autotrust tests, fix trustpoint timer deletion code.
5496 fix count of valid anchors during missing remove.

5509 - iana portlist updated.
5511 10 September 2009: Wouter
5512 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
5513 - use linebuffering for log-file: output, this can be significantly
5514 faster than the previous fflush method and enable some class of
5515 resolvers to use high verbosity (for short periods).
5516 Not on windows, because line buffering does not work there.
5518 9 September 2009: Wouter
5519 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
5520 The RRsets would still expire at the normal time, but this would
5521 keep messages bogus in the cache for too long.
5522 - regression test for that bug.
5523 - documented that load_cache is meant for debugging.
5525 8 September 2009: Wouter

5683 - updated ldns tarball for solaris x64 compile assistance.
5684 - no need to define RAND_MAX from config.h.
5685 - iana portlist updated.
5686 - configure changes and ldns update for mingw32 crosscompile.
5688 13 July 2009: Wouter
5689 - Fix for crash at start on windows.
5690 - tag for release 1.3.2.
5691 - trunk has version 1.3.3.
5692 - Fix for ID bits on windows to use all 16. RAND_MAX was not
5693 defined like you'd expect on mingw. Reported by Mees de Roo.

5710 30 June 2009: Wouter
5711 - more lenient truncation checks.
5713 29 June 2009: Wouter
5714 - ldns trunk r2959 imported as tarball, because of solaris cc compile
5715 support for c99. r2960 for better configure.
5716 - better wrongly_truncated check.
5717 - On Linux, fragment IPv6 datagrams to the IPv6 minimum MTU, to
5718 avoid dropped packets at routers.
5720 26 June 2009: Wouter
5721 - Fix EDNS fallback when EDNS works for short answers but long answers
5724 22 June 2009: Wouter
5725 - fixup iter priv strict aliasing while preserving size of sockaddr.
5726 - iana portlist updated. (one less port allocated, one more fraction
5727 of a bit for security!)
5728 - updated fedora specfile in contrib from Paul Wouters.
5730 19 June 2009: Wouter
5731 - Fixup strict aliasing warning in iter priv code.
5732 and config_file code.
5733 - iana portlist updated.
5734 - harden-referral-path: handle cases where NS is in answer section.
5736 18 June 2009: Wouter
5737 - Fix of message parse bug where (specifically) an NSEC and RRSIG
5738 in the wrong order would be parsed, but put wrongly into internal
5739 structures so that later validation would fail.
5740 - Extreme lenience for wrongly truncated replies where a positive
5741 reply has an NS in the authority but no signatures. They are
5742 turned into minimal responses with only the (secure) answer.
5743 - autoconf 2.63 for configure.
5744 - python warnings suppress. Keep python API away from header files.
5746 17 June 2009: Wouter
5747 - CREDITS entry for cz.nic, sponsoring a 'summer of code' that was
5748 used for the python code in unbound. (http://www.nic.cz/vip/ in cz).
5750 16 June 2009: Wouter
5751 - Fixup opportunistic target query generation to it does not
5752 generate queries that are known to fail.
5753 - Touchup on munin total memory report.
5754 - messages picked out of the cache by the iterator are checked
5755 if their cname chain is still correct and if validation status
5756 has to be reexamined.
5758 15 June 2009: Wouter
5759 - iana portlist updated.
5761 14 June 2009: Wouter
5762 - Fixed bug where cached responses would lose their security
5763 status on second validation, which especially impacted dlv
5764 lookups. Reported by Hauke Lampe.
5766 13 June 2009: Wouter
5767 - bug #254. removed random whitespace from example.conf.
5769 12 June 2009: Wouter
5770 - Fixup potential wrong NSEC picked out of the cache.
5771 - If unfulfilled callbacks are deleted they are called with an error.
5772 - fptr wlist checks for mesh callbacks.
5773 - fwd above stub in configuration works.
5775 11 June 2009: Wouter
5776 - Fix queries for type DS when forward or stub zones are there.
5777 They are performed to higherup domains, and thus treated as if
5778 going to higher zones when looking up the right forward or stub
5779 server. This makes a stub pointing to a local server that has
5780 a local view of example.com signed with the same keys as are
5781 publicly used work. Reported by Johan Ihren.
5782 - Added build-unbound-localzone-from-hosts.pl to contrib, from
5783 Dennis DeDonatis. It converts /etc/hosts into config statements.
5784 - same thing fixed for forward-zone and DS, chain of trust from
5785 public internet into the forward-zone works now. Added unit test.
5788 - openssl key files are opened apache-style, when user is root and
5789 before chrooting. This makes permissions on remote-control key
5790 files easier to set up. Fixes bug #251.
5791 - flush_type and flush_name remove msg cache entries.
5792 - codereview - dp copy bogus setting fix.
5795 - Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
5796 inadvertant behaviour.
5797 - 1.3.0 tarball for release created.
5798 - 1.3.1 development in svn trunk.
5799 - iana portlist updated.
5800 - fix lint from complaining on ldns/sha.h.
5801 - help compiler figure out aliasing in priv_rrset_bad() routine.
5802 - fail to configure with python if swig is not found.
5803 - unbound_munin_ in contrib uses ps to show rss if sbrk does not work.
5806 - fixup bad free() when wrongly encoded DSA signature is seen.
5807 Reported by Paul Wouters.
5808 - review comments from Matthijs.
5811 - --enable-sha2 option. The draft rsasha256 changed its algorithm
5812 numbers too often. Therefore it is more prudent to disable the
5813 RSASHA256 and RSASHA512 support by default.
5814 - ldns trunk included as new tarball.
5815 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.
5818 - fixup doc bug in README reported by Matthew Dempsky.
5821 - update iana port list
5822 - update ldns lib tarball
5825 - detect lack of IPv6 support on XP (with a different error code).
5826 - Fixup a crash-on-exit which was triggered by a very long queue.
5827 Unbound would try to re-use ports that came free, but this is
5828 of course not really possible because everything is deleted.
5829 Most easily triggered on XP (not Vista), maybe because of the
5830 network stack encouraging large messages backlogs.
5831 - change in debug statements.
5832 - Fixed bug that could cause a crash if root prime failed when there
5833 were message backlogs.
5836 - Thanks again to Brett Carr, found an assertion that was not true.
5837 Assertion checked if recursion parent query still existed.
5839 29 April 2009: Wouter
5840 - Thanks to Brett Carr, caught windows resource leak, use
5841 closesocket() and not close() on sockets or else the network stack
5842 starts to leak handles.
5843 - Removed usage of windows Mutex because windows cannot handle enough
5844 mutexes open. Provide own mutex implementation using primitives.
5846 28 April 2009: Wouter
5847 - created svn tag for 1.3.0.
5849 27 April 2009: Wouter

5869 - faster fix for winsock reentrant check.
5870 - fix rsasha512 unit test for new (interim) algorithm number.
5871 - fix test:ldns doesn't like DOS line endings in keyfiles on unix.
5872 - fix compile warning on ubuntu (configlexer fwrite return value).
5873 - move python include directives into CPPFLAGS instead of CFLAGS.
5875 16 April 2009: Wouter
5876 - winsock event handler exit very quickly on signal, even if
5878 - iana portlist updated.

5889 - ldns tarball updated.
5890 - iana portlist update.
5891 - detect GOST support in openssl-1.0.0-beta1, and fix compile problem
5892 because that openssl defines the name STRING for itself.
5894 6 April 2009: Wouter
5895 - windows compile fix.
5896 - Detect FreeBSD jail without ipv6 addresses assigned.
5897 - python libunbound wrapper unit test.

5899 from configure --with-pythonmodule:
5900 /usr/lib/python2.x/site-packages/unboundmodule.py
5901 from configure --with-pyunbound:
5902 /usr/lib/python2.x/site-packages/unbound.py
5903 /usr/lib/python2.x/site-packages/_unbound.so*
5904 The example python scripts (pythonmod/examples and
5905 libunbound/python/examples) are not installed.
5906 - python invalidate routine respects packed rrset ids and locks.
5907 - clock skew checks in unbound, config statements.
5908 - nxdomain ttl considerations in requirements.txt
5910 3 April 2009: Wouter
5911 - Fixed a bug that caused messages to be stored in the cache too
5912 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
5913 targets have been more vulnerable to the TTL miscalculation bug.
5914 - documentation test fixed for python addition.
5916 2 April 2009: Wouter
5917 - pyunbound (libunbound python plugin) compiles using libtool.

5919 - iana portlist updated.
5920 - fixed bug in unbound-control flush_zone where it would not flush
5921 every message in the target domain. This especially impacted
5922 NXDOMAIN messages which could remain in the cache regardless.
5923 - python module test package.
5925 1 April 2009: Wouter
5926 - suppress errors when trying to contact authority servers that gave
5927 ipv6 AAAA records for their nameservers with ipv4 mapped contents.
5928 Still tries to do so, could work when deployed in intranet.
5929 Higher verbosity shows the error.

5981 - defaults for windows baked into configure.ac (used if on mingw).
5983 18 March 2009: Wouter
5984 - Added tests, unknown algorithms become insecure. fallback works.
5985 - Fix for and test for unknown algorithms in a trust anchor
5986 definition. Trust anchors with no supported algos are ignored.
5987 This means a (higher)DS or DLV entry for them could succeed, and
5988 otherwise they are treated as insecure.
5989 - domain-insecure: "example.com" statement added. Sets domain
5990 insecure regardless of chain of trust DSs or DLVs. The inverse
5993 17 March 2009: Wouter
5994 - unit test for unsupported algorithm in anchor warning.
5995 - fixed so queries do not fail on opportunistic target queries.
5997 16 March 2009: Wouter

6004 - strip update-anchor on makedist -w.
6005 - fix testbound on windows.
6006 - default log to syslog for windows.
6007 - uninstaller can stop unbound - changed text on it to reflect that.
6008 - remove debugging from windows 'cron' actions.
6010 12 March 2009: Wouter
6011 - log to App.logs on windows prints executable identity.
6013 - munin plugin fix benign locking error printout.
6014 - anchor-update for windows, called every 24 hours; unbound reloads.
6016 11 March 2009: Wouter
6017 - winsock event handler resets WSAevents after signalled.
6018 - winsock event handler tests if signals are really signalled.
6019 - install and service with log to file works on XP and Vista on
6020 default install location.
6021 - on windows logging to the Application logbook works (as a service).
6022 - fix RUN_DIR on windows compile setting in makedist.
6023 - windows registry has Software\Unbound\ConfigFile element.
6024 If does not exist, the default is used. The -c switch overrides it.
6025 - fix makedist version cleanup function.
6027 10 March 2009: Wouter
6028 - makedist -w strips out old rc.. and snapshot info from version.
6029 - setup.exe starts and stops unbound after install, before uninstall.

6045 This should fix extraneous symbols exported from libunbound.
6046 Thanks to Ondrej Sury and Robert Edmonds for finding it.
6047 - iana portlist updated.
6048 - document FAQ entry on stub/forward zones and default blocking.
6049 - fix asynclook test app for libunbound not exporting symbols.

6069 Nicer script layout. Added url to site in -h output.
6071 19 February 2009: Wouter
6072 - unbound-checkconf and unbound print warnings when trust anchors
6073 have unsupported algorithms.
6074 - added contrib/update-itar.sh This script is similar to
6075 update-anchor.sh, and updates from the IANA ITAR repository.
6076 You can provide your own PGP key and trust repo, or can use the
6077 builtin. The program uses wget and gpg to work.
6078 - iana portlist updated.
6079 - update-itar.sh: using ftp:// urls because https godaddy certificate
6080 is not available everywhere and then gives fatal errors. The
6081 security is provided by pgp signature.
6083 18 February 2009: Wouter
6084 - more cycle detection. Also for target queries.
6085 - fixup bug where during deletion of the mesh queries the callbacks
6086 that were reentrant caused assertion failures. Keep the mesh in
6087 a reentrant safe state. Affects libunbound, reload of server,
6088 on quit and flush_requestlist.
6089 - iana portlist updated.
6091 13 February 2009: Wouter
6092 - forwarder information now per-thread duplicated.
6093 This keeps it read only for speed, with no locking necessary.
6094 - forward command for unbound control to change forwarders to use
6096 - document that unbound-host reads no config file by default.
6097 - updated iana portlist.
6099 12 February 2009: Wouter
6100 - call setusercontext if available (on BSD).
6101 - small refactor of stats clearing.
6102 - #227: flush_stats feature for unbound-control.
6103 - stats_noreset feature for unbound-control.
6104 - flush_requestlist feature for unbound-control.
6105 - libunbound version upped API (was changed 5 feb).
6106 - unbound-control status shows if root forwarding is in use.
6107 - slightly nicer memory management in iter-fwd code.
6109 10 February 2009: Wouter
6110 - keys with rfc5011 REVOKE flag are skipped and not considered when
6112 - iana portlist updated
6113 - #226: dump_requestlist feature for unbound-control.
6115 6 February 2009: Wouter
6116 - contrib contains specfile for fedora 1.2.1 (from Paul Wouters).

6118 - fixup EOL in include directive (reported by Paul Wouters).
6119 You can no longer specify newlines in the names of included files.
6120 - config parser changed. Gives some syntax errors closer to where they
6121 occurred. Does not enforce a space after keyword anymore.
6122 Does not allow literal newlines inside quoted strings anymore.
6123 - verbosity level 5 logs customer IP for new requestlist entries.
6124 - test fix, lexer and cancel test.
6125 - new option log-time-ascii: yes if you enable it prints timestamps
6126 in the log file as Feb 06 13:45:26 (like syslog does).
6127 - detect event_base_new in libevent-1.4.1 and later and use it.
6128 - #231 unbound-checkconf -o option prints that value from config file.
6129 Useful for scripting in management scripts and the like.
6131 5 February 2009: Wouter
6132 - ldns 1.5.0 rc as tarball included.
6133 - 1.3.0 development continues:
6134 change in libunbound API: ub_cancel can return an error, that
6135 the async_id did not exist, or that it was already delivered.
6136 The result could have been delivered just before the cancel
6137 routine managed to acquire the lock, so a caller may get the
6138 result at the same time they call cancel. For this case,
6139 ub_cancel tries to return an error code.
6140 Fixes race condition in ub_cancel() libunbound function.
6141 - MacOSX Leopard cleaner text output from configure.
6142 - initgroups(3) is called to drop secondary group permissions, if
6144 - configure option --with-ldns-builtin forces the use of the
6145 inluded ldns package with the unbound source. The -I include
6146 is put before the others, so it avoids bad include files from
6147 an older ldns install.
6148 - daemon(3) posix call is used when available.
6149 - testbound test for older fix added.
6151 4 February 2009: Wouter
6152 - tag for release 1.2.1.
6153 - trunk setup for 1.3.0 development.
6155 3 February 2009: Wouter
6156 - noted feature requests in doc/TODO.
6157 - printout more detailed errors on ssl certificate loading failures.
6158 - updated IANA portlist.
6160 16 January 2009: Wouter
6161 - more quiet about ipv6 network failures, i.e. when ipv6 is not
6162 available (network unreachable). Debug still printed on high
6164 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
6165 debugging with unbound-host -4 -d ...
6166 - more cycle detection for NS-check, addr-check, root-prime and
6167 stub-prime queries in the iterator. Avoids possible deadlock
6170 15 January 2009: Wouter
6171 - bug #229: fixup configure checks for compilation with Solaris
6172 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc
6173 - fixup suncc warnings.
6174 - fix bug where unbound could crash using libevent 1.3 and older.
6175 - update testset for recent retry change.
6177 14 January 2009: Wouter
6178 - 1.2.1 feature: negative caching for failed queries.
6179 Queries that failed are cached for 5 seconds (NORR_TTL).
6180 If the failure is local, like out of memory, it is not cached.
6181 - the TTL comparison for the cache used different comparisons,
6182 causing many cache responses that used the iterator and validator
6183 state machines unnecessarily.
6184 - retry from 4 to 5 so that EDNS drop retry is part of the first
6185 query resolve attempt, and cached error does not stop EDNS fallback.
6186 - remove debug prints that protect against bad referrals.
6187 - honor QUIET=no on make commandline (or QUIET=yes ).
6189 13 January 2009: Wouter
6190 - fixed bug in lameness marking, removed printouts.
6191 - find NS rrset more cleanly for qtype NS.
6192 - Moved changes to 1.2.0 for release. Thanks to Mark Zealey for
6194 - 1.2.1 feature: stops resolving AAAAs promiscuously when they
6195 are in the negative cache.
6197 12 January 2009: Wouter
6198 - fixed bug in infrastructure lameness cache, did not lowercase
6199 name of zone to hash when setting lame.
6200 - lameness debugging printouts.
6202 9 January 2009: Wouter
6203 - created svn tag for 1.2.0 release.
6204 - svn trunk contains 1.2.1 version number.

6216 statements. (Adapted from patch by Paul Wouters).
6217 - typo fix and iana portlist updated.
6218 - porting testsuite; unused var warning, and type fixup.
6220 6 January 2009: Wouter

6222 A malformed packet could cause an internal assertion failure.
6223 - added test for HINFO canonicalisation behaviour.
6224 - fixup reported problem with transparent local-zone data where
6225 queries with different type could get nxdomain. Now queries
6226 with a different name get resolved normally, with different type
6227 get a correct NOERROR/NODATA answer.
6228 - HINFO no longer downcased for validation, making unbound compatible
6230 - fix reading included config files when chrooted.
6231 Give full path names for include files.

6243 some zones that had correct DLV keys as insecure.
6244 - follows -rc makedist from ldns changes (no _rc).
6245 - ldns tarball updated with 1.4.1rc for DLV unit test.
6246 - verbose prints about recursion lame detection and server selection.
6247 - fixup BSD port for infra host storage. It hashed wrongly.

6253 - unbound-control status command.
6254 - extended statistics has a number of ipv6 queries counter.
6255 contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
6257 16 December 2008: Wouter
6258 - follow makedist improvements from ldns, for maintainers prereleases.
6259 - snapshot version uses _ not - to help rpm distinguish the
6262 11 December 2008: Wouter

6264 Thanks to Tamas Tevesz.
6266 9 December 2008: Wouter
6267 - bug #221 fixed: unbound checkconf checks if key files exist if

6269 - iana portlist updated.
6271 3 December 2008: Wouter
6272 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
6273 freezes up unbound if this was compiled without threading, and
6274 was using multiple processes.
6275 - iana portlist updated.
6276 - test for remote control with interprocess communication.
6277 - created command distribution mechanism so that remote control
6278 commands other than 'stats' work on all processes in a nonthreaded
6279 compiled version. dump/load cache work, on the first process.
6280 - fixup remote control local_data addition memory corruption bug.
6282 1 December 2008: Wouter
6283 - SElinux policy files in contrib/selinux for the unbound daemon,
6284 by Paul Wouters and Adam Tkac.
6286 25 November 2008: Wouter
6287 - configure complains when --without-ssl is given (bug #220).
6288 - skip unsupported feature tests on vista/mingw.
6289 - fixup testcode/streamtcp to work on vista/mingw.
6290 - root-hints test checks version of dig required.
6291 - blacklisted servers are polled at a low rate (1%) to see if they
6292 come back up. But not if there is some other working server.
6294 24 November 2008: Wouter
6295 - document that the user of the server daemon needs read privileges
6296 on the keys and certificates generated by unbound-control-setup.
6297 This is different per system or distribution, usually, running the
6298 script under the same username as the server uses suffices.
6299 i.e. sudo -u unbound unbound-control-setup
6300 - testset port to vista/mingw.
6301 - tcp_sigpipe to freebsd port.
6303 21 November 2008: Wouter
6304 - fixed tcp accept, errors were printed when they should not.
6305 - unbound-control-setup.sh removes read/write permissions other
6306 from the keys it creates (as suggested by Dmitriy Demidov).
6308 20 November 2008: Wouter
6309 - fixup fatal error due to faulty error checking after tcp accept.
6310 - add check in rlimit to avoid integer underflow.
6311 - rlimit check with new formula; better estimate for number interfaces
6312 - nicer comments in rlimit check.
6313 - tag 1.1.1 created in svn.
6314 - trunk label is 1.1.2
6316 19 November 2008: Wouter
6317 - bug #219: fixed so that syslog which delays opening until the first
6318 log line is written, gets a log line while not chroot'ed yet.
6320 18 November 2008: Wouter
6321 - iana portlist updated.
6322 - removed cast in unit test debug print that was not 64bit safe.
6323 - trunk back to 1.1.0; copied to tags 1.1.0 release.
6324 - trunk to has version number 1.1.1 again.
6325 - in 1.1.1; make clean nicer. grammar in manpage.
6327 17 November 2008: Wouter
6328 - theoretical fix for problems reported on mailing list.
6329 If a delegation point has no A but only AAAA and do-ip6 is no,
6330 resolution would fail. Fixed to ask for the A and AAAA records.
6331 It has to ask for both always, so that it can fail quietly, from
6332 TLD perspective, when a zone is only reachable on one transport.
6333 - test for above, only AAAA and doip6 is no. Fix causes A record
6334 for nameserver to be fetched.
6335 - fixup address duplication on cache fillup for delegation points.
6336 - testset updated for new query answer requirements.

6346 - neater comments in worker.h.
6347 - removed doc/plan and updated doc/TODO.
6348 - silenced EHOSTDOWN (verbosity 2 or higher to see it).
6349 - review comments from Jelte, Matthijs. Neater code.
6351 12 November 2008: Wouter
6352 - add unbound-control manpage to makedist replace list.
6354 11 November 2008: Wouter
6355 - unit test for negative cache, stress tests the refcounting.
6356 - fix for refcounting error that could cause fptr_wlist fatal exit
6357 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
6358 Attila Nagy for testing).
6359 - nicer comments in cachedump about failed RR to string conversion.
6360 - fix 32bit wrap around when printing large (4G and more) mem usage
6361 for extended statistics.

6375 - iana portlist updated.
6377 5 November 2008: Wouter
6378 - fixed possible memory leak in key_entry_key deletion.
6379 Would leak a couple bytes when trust anchors were replaced.
6380 - if query and reply qname overlap, the bytes are skipped not copied.
6381 - fixed file descriptor leak when messages were jostled out that
6382 had outstanding (TCP) replies.
6383 - DNAMEs used from cache have their synthesized CNAMEs initialized
6385 - fixed file descriptor leak for localzone type deny (for TCP).
6386 - fixed memleak at exit for nsec3 negative cached zones.
6387 - fixed memleak for the keyword 'nodefault' when reading config.
6388 - made verbosity of 'edns incapable peer' warning higher, so you
6389 do not get spammed by it.
6390 - caught elusive Bad file descriptor error bug, that would print the
6391 error while unnecessarily try to listen to a closed fd. Fixed.
6393 4 November 2008: Wouter
6394 - fixed -Wwrite-strings warnings that result in better code.
6396 3 November 2008: Wouter
6397 - fixup build process for Mac OSX linker, use ldns b32 compat funcs.
6398 - generated configure with autoconf-2.61.
6399 - iana portlist updated.
6400 - detect if libssl needs libdl. For static linking with libssl.
6401 - changed to use new algorithm identifiers for sha256/sha512
6402 from ldns 1.4.0 (need very latest version).
6403 - updated the included ldns tarball.
6404 - proper detection of SHA256 and SHA512 functions (not just sizes).
6406 23 October 2008: Wouter
6407 - a little more debug info for failure on signer names. prints names.
6409 22 October 2008: Wouter
6410 - CFLAGS are picked up by configure from the environment.
6411 - iana portlist updated.
6412 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
6413 - new stub-prime: yesno option. Default is off, so it does not prime.
6414 can be turned on to get same behaviour as previous unbound release.
6415 - made automated test that checks if builtin root hints are uptodate.
6416 - finished draft-wijngaards-dnsext-resolver-side-mitigation
6417 implementation. The unwanted-reply-threshold can be set.
6418 - fixup so fptr_whitelist test in alloc.c works.
6420 21 October 2008: Wouter
6421 - fix update-anchors.sh, so it does not report different RR order
6422 as an update. Sorts the keys in the file. Updated copyright.
6423 - fixup testbound on windows, the command control pipe doesn't exist.
6424 - skip 08hostlib test on windows, no fork() available.
6425 - made unbound-remote work on windows.
6427 20 October 2008: Wouter
6428 - quench a log message that is debug only.
6429 - iana portlist updated.
6430 - do not query bogus nameservers. It is like nameservers that have
6431 the NS or A or AAAA record bogus are listed as donotquery.
6432 - if server selection is faced with only bad choices, it will
6433 attempt to get more options to be fetched.
6434 - changed bogus-ttl default value from 900 to 60 seconds.
6435 In anticipation that operator caused failures are more likely than
6436 actual attacks at this time. And thus repeated validation helps
6437 the operators get the problem fixed sooner. It makes validation
6438 failures go away sooner (60 seconds after the zone is fixed).
6439 Also it is likely to try different nameserver targets every minute,
6440 so that if a zone is bad on one server but not another, it is
6441 likely to pick up the 'correct' one after a couple minutes,
6442 and if the TTL is big enough that solves validation for the zone.
6443 - fixup unbound-control compilation on windows.
6445 17 October 2008: Wouter
6446 - port Leopard/G5: fixup type conversion size_t/uint32.
6447 please ranlib, stop file without symbols warning.
6448 - harden referral path now also validates the root after priming.
6449 It looks up the root NS authoritatively as well as the root servers
6450 and attemps to validate the entries.
6452 16 October 2008: Wouter
6453 - Fixup negative TTL values appearing (reported by Attila Nagy).
6455 15 October 2008: Wouter
6456 - better documentation for 0x20; remove fallback TODO, it is done.
6457 - harden-referral-path feature includes A, AAAA queries for glue,
6458 as well as very careful NS caching (only when doing NS query).
6459 A, AAAA use the delegation from the NS-query.
6461 14 October 2008: Wouter
6462 - fwd_three.tpkg test was flaky. If the three requests hit the
6463 wrong threads by chance (or bad OS) then the test would fail.
6464 Made less flaky by increasing number of retries.
6465 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
6466 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
6467 Which includes the ldns_dname_absolute fix.
6468 - fwd_three test remains flaky now that unbound does not stop
6469 listening when full. Thus, removed timeout problem.
6470 It may be serviced by three threads, or maybe by one.
6471 Mostly only useful for lock-check testing now.
6473 13 October 2008: Wouter
6474 - fixed recursion servers deployed as authoritative detection, so
6475 that as a last resort, a +RD query is sent there to get the
6477 - iana port list update.
6478 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
6480 10 October 2008: Wouter
6481 - fixup tests - the negative cache contained the correct NSEC3s for
6482 two tests that are supposed to fail to validate.
6484 9 October 2008: Wouter
6485 - negative cache caps max iterations of NSEC3 done.
6486 - NSEC3 negative cache for qtype DS works.
6488 8 October 2008: Wouter
6489 - NSEC negative cache for DS.
6491 6 October 2008: Wouter
6492 - jostle-timeout option, so you can config for slow links.
6493 - 0x20 fallback code. Tries 3xnumber of nameserver addresses
6494 queries that must all be the same. Sent to random nameservers.
6495 - documented choices for DoS, EDNS, 0x20.
6497 2 October 2008: Wouter
6498 - fixup unlink of pidfile.
6499 - fixup SHA256 algorithm collation code.
6500 - contrib/update-anchor.sh does not overwrite anchors if not needed.
6501 exits 0 when a restart is needed, other values if not.
6502 so, update-anchor.sh -d mydir && /etc/rc.d/unbound restart
6503 can restart unbound exactly when needed.
6505 30 September 2008: Wouter
6506 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
6507 - tests for sha256 support and downgrade resistance.
6508 - RSASHA256 and RSASHA512 support (using the draft in dnsext),
6509 using the drafted protocol numbers.
6510 - when using stub on localhost (127.0.0.1@10053) unbound works.
6511 Like when running NSD to host a local zone, on the same machine.
6512 The noprime feature. manpages more explanation. Added a test for it.
6513 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
6515 29 September 2008: Wouter
6516 - EDNS lameness detection, if EDNS packets are dropped this is
6517 detected, eventually.
6518 - multiple query timeout rtt backoff does not backoff too much.
6520 26 September 2008: Wouter
6521 - tests for remote-control.
6522 - small memory leak in exception during remote control fixed.

6550 - ldns tarball updated.
6551 - testcode/ldns-testpkts.c const fixups.
6552 - fixed rcode stat printout.

6592 - private-address and private-domain config option read, stored.
6594 2 September 2008: Wouter
6595 - DoS protection features. Queries are jostled out to make room.
6596 - testbound can pass time, increasing the internal timer.
6597 - do not mark unsigned additionals bogus, leave unchecked, which
6600 1 September 2008: Wouter
6601 - disallow nonrecursive queries for cache snooping by default.
6602 You can allow is using access-control: <subnet> allow_snoop.

6613 again. (from bugfix#199).
6614 Some errors are not written to logfile (pidfile writing, forking),
6615 and these are only visible by using the -d commandline flag.
6617 27 August 2008: Wouter
6618 - daemon(3) is causing problems for people. Reverting the patch.
6619 bug#200, and 199 and 203 contain sideline discussion on it.
6620 - bug#199 fixed: pidfile can be outside chroot. openlog is done before
6621 chroot and drop permissions.
6622 - config option to set size of aggressive negative cache,
6624 - bug#203 fixed: dlv has been implemented.
6626 26 August 2008: Wouter
6627 - test for insecure zone when DLV is in use, also does negative cache.

6679 11 August 2008: Wouter
6680 - Fixup rrset security updates overwriting 2181 trust status.
6681 This makes validated to be insecure data just as worthless as
6682 nonvalidated data, and 2181 rules prevent cache overwrites to them.
6683 - Fix assertion fail on bogus key handling.
6684 - dnssec lameness detection works on first query at trust apex.
6685 - NS queries get proper cache and dnssec lameness treatment.

6780 - skip tests that need signals when testing on mingw.
6782 18 June 2008: Wouter
6783 - open testbound replay files in binary mode, because fseek/ftell

6973 - automatic iana ports update from makefile. 60058 available.
6975 9 April 2008: Wouter
6976 - configure can detect libev(from its build directory) when passed
6977 --with-libevent=/home/wouter/libev-3.2
6978 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
6979 - unused commpoints not listed in epoll list.
6980 - statistics-cumulative option so that the values are not reset.
6981 - config creates array of available ports, 61841 available,
6982 it excludes <1024 and iana assigned numbers.
6983 config statements to modify the available port numbers.
6985 8 April 2008: Wouter
6986 - unbound tries to set the ulimit fds when started as server.
6987 if that does not work, it will scale back its requirements.
6989 27 March 2008: Wouter
6990 - documented /dev/random symlink from chrootdir as FAQ entry.
6992 26 March 2008: Wouter
6993 - implemented AD bit signaling. If a query sets AD bit (but not DO)
6994 then the AD bit is set in the reply if the answer validated.
6995 Without including DNSSEC signatures. Useful if you have a trusted
6996 path from the client to the resolver. Follows dnssec-updates draft.
6998 25 March 2008: Wouter
6999 - implemented check that for NXDOMAIN and NOERROR answers a query
7000 section must be present in the reply (by the scrubber). And it must
7001 be equal to the question sent, at least lowercase folded.
7002 Previously this feature happened because the cache code refused
7003 to store such messages. However blocking by the scrubber makes
7004 sure nothing gets into the RRset cache. Also, this looks like a
7005 timeout (instead of an allocation failure) and this retries are
7006 done (which is useful in a spoofing situation).
7007 - RTT banding. Band size 400 msec, this makes band around zero (fast)
7008 include unknown servers. This makes unbound explore unknown servers.
7010 7 March 2008: Wouter
7011 - -C config feature for harvest program.
7012 - harvest handles CNAMEs too.
7014 5 March 2008: Wouter
7015 - patch from Hugo Koji Kobayashi for iterator logs spelling.
7017 4 March 2008: Wouter
7018 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
7019 of a cname trust chain is lower; not full answer_AA.
7020 - test for this fix.
7021 - default config file location is /usr/local/etc/unbound.
7022 Thus prefix is used to determine the location. This is also the
7023 chroot and pidfile default location.
7025 3 March 2008: Wouter
7026 - Create 0.10 svn tag.
7027 - 0.11 version in trunk.
7028 - indentation nicer.

7039 - harvest performs lookup.
7040 - ldns-tarball update with fix for ldns_dname_label.
7041 - installs to sbin by default.
7042 - install all manual pages (unbound-host and libunbound too).
7044 27 February 2008: Wouter
7045 - option to use caps for id randomness.
7046 - config file option use-caps-for-id: yes
7047 - harvest debug tool
7049 26 February 2008: Wouter
7050 - delay utility delays TCP as well. If the server that is forwarded
7051 to has a TCP error, the delay utility closes the connection.
7052 - delay does REUSE_ADDR, and can handle a server that closes its end.
7053 - answers use casing from query.
7055 25 February 2008: Wouter
7056 - delay utility works. Gets decent thoughput too (>20000).
7058 22 February 2008: Wouter
7059 - +2% for recursions, if identical queries (except for destination
7060 and query ID) in the reply list, avoid re-encoding the answer.
7061 - removed TODO items for optimizations that do not show up in
7063 - default is now minievent - not libevent. As its faster and
7064 not needed for regular installs, only for very large port ranges.
7065 - loop check different speedup pkt-dname-reading, 1% faster for
7066 nocache-recursion check.
7067 - less hashing during msg parse, 4% for recursion.
7068 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
7069 - some speed results noted:
7070 optimization resulted in +40% for recursion (cache miss) and
7071 +70 to +80 for cache hits, and +96% for version.bind.
7072 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
7073 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
7074 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
7075 So, unbound can be about equal qps to NSD in cache hits.
7076 And about 3.4x faster than BIND in cache performance.
7077 - delay utility for testing.
7079 21 February 2008: Wouter
7080 - speedup of root-delegation message encoding by 15%.
7081 - minor speedup of compress tree_lookup, maybe 1%.
7082 - speedup of dname_lab_cmp and memlowercmp - the top functions in
7083 profiler output, maybe a couple percent when it matters.
7085 20 February 2008: Wouter
7086 - setup speec_cache for need-ldns-testns in dotests.
7087 - check number of queued replies on incoming queries to avoid overload
7089 - fptr whitelist checks are not disabled in optimize mode.
7090 - do-daemonize config file option.
7091 - minievent time share initializes time at start.
7092 - updated testdata for nsec3 new algorithm numbers (6, 7).
7093 - small performance test of packet encoding (root delegation).
7095 19 February 2008: Wouter
7096 - applied patch to unbound-host man page from Jan-Piet Mens.
7097 - fix donotquery-localhost: yes default (it erroneously was switched
7099 - time is only gotten once and the value is shared across unbound.
7100 - unittest cleans up crypto, so that it has no memory leaks.
7101 - mini_event shares the time value with unbound this results in
7102 +3% speed for cache responses and +9% for recursions.
7103 - ldns tarball update with new NSEC3 sign code numbers.
7104 - perform several reads per UDP operation. This improves performance
7105 in DoS conditions, and costs very little in normal conditions.
7106 improves cache response +50%, and recursions +10%.
7107 - modified asynclook test. because the callback from async is not
7108 in any sort of lock (and thus can use all library functions freely),
7109 this causes a tiny race condition window when the last lock is
7110 released for a callback and a new cancel() for that callback.
7111 The only way to remove this is by putting callbacks into some
7112 lock window. I'd rather have the small possibility of a callback
7113 for a cancelled function then no use of library functions in
7114 callbacks. Could be possible to only outlaw process(), wait(),
7115 cancel() from callbacks, by adding another lock, but I'd rather not.
7117 18 February 2008: Wouter
7118 - patch to unbound-host from Jan-Piet Mens.
7119 - unbound host prints errors if fails to configure context.
7120 - fixup perf to resend faster, so that long waiting requests do
7121 not hold up the queue, they become lost packets or SERVFAILs,
7122 or can be sent a little while later (i.e. processing time may
7123 take long, but throughput has to be high).
7124 - fixup iterator operating in no cache conditions (RD flag unset
7126 - streamlined code for RD flag setting.
7127 - profiled code and changed dname compares to be faster.
7128 The speedup is about +3% to +8% (depending on the test).
7129 - minievent tests for eintr and eagain.
7131 15 February 2008: Wouter
7132 - added FreeBSD rc.d script to contrib.
7133 - --prefix option for configure also changes directory: pidfile:
7134 and chroot: defaults in config file.
7135 - added cache speed test, for cache size OK and cache too small.
7137 14 February 2008: Wouter
7138 - start without a config file (will complain, but start with
7140 - perf test program works.

7167 makedist, list asynclook and tcpstream tests as ldns-testns
7170 7 February 2008: Wouter
7171 - moved up all current level 2 to be level 3. And 3 to 4.
7172 to make room for new debug level 2 for detailed information
7174 - verbosity level 2. Describes recursion and validation.

7178 6 February 2008: Wouter
7179 - clearer explanation of threading configure options.
7180 - fixup asynclook test for nothreading (it creates only one process
7181 to do the extended test).
7182 - changed name of ub_val_result_free to ub_val_resolve_free.
7183 - removes warning message during library linking, renamed
7184 libunbound/unbound.c -> libunbound.c and worker to libworker.

7193 31 January 2008: Wouter
7194 - bg thread/process reads and writes the pipe nonblocking all the time
7195 so that even if the pipe is buffered or so, the bg thread does not
7196 block, and services both pipes and queries.
7198 30 January 2008: Wouter
7199 - check trailing / on chrootdir in checkconf.
7200 - check if root hints and anchor files are in chrootdir.

7230 a mutex around the rand init.
7231 - fix pass async_id=NULL to _async resolve().
7232 - rewrote _wait() routine, so that it is threadsafe.
7233 - cancelation is threadsafe.
7234 - asynclook extended test in tpkg.
7235 - fixed two races where forked bg process waits for (somehow shared?)
7236 locks, so does not service the query pipe on the bg side.
7237 Now those locks are only held for fg_threads and for bg_as_a_thread.
7239 24 January 2008: Wouter
7240 - tested the cancel() function.
7241 - asynclook -c (cancel) feature.

7245 - fix Makefile for concurrent make of unbound-host.
7246 - renamed ub_val_ctx_wait/poll/process/fd to ub_val*.
7247 - new calls to set forwarding added to header and docs.
7249 23 January 2008: Wouter
7250 - removed debug prints from if-auto, verb-algo enables some.
7251 - libunbound QUIT setup, remove memory leaks, when using threads
7252 will share memory for passing results instead of writing it over
7253 the pipe, only writes ID number over the pipe (towards the handler
7254 thread that does process() ).
7256 22 January 2008: Wouter
7257 - library code for async in libunbound/unbound.c.
7258 - fix link testbound.
7259 - fixup exit bug in mini_event.
7260 - background worker query enter and result functions.
7261 - bg query test application asynclook, it looks up multiple
7262 hostaddresses (A records) at the same time.
7264 21 January 2008: Wouter
7265 - libworker work, netevent raw commpoints, write_msg, serialize.
7267 18 January 2008: Wouter
7268 - touch up of manpage for libunbound.
7269 - support for IP_RECVDSTADDR (for *BSD ip4).
7270 - fix for BSD, do not use ip4to6 mapping, make two sockets, once
7271 ip6 and once ip4, uses socket options.
7272 - goodbye ip4to6 mapping.
7273 - update ldns-testpkts with latest version from ldns-trunk.
7274 - updated makedist for relative ldns pathnames.
7275 - library API with more information inside the result structure.
7276 - work on background resolves.
7278 17 January 2008: Wouter
7279 - fixup configure in case -lldns is installed.
7280 - fixup a couple of doxygen warnings, about enum variables.
7281 - interface-automatic now copies the interface address from the
7282 PKT_INFO structure as well.
7283 - manual page with library API, all on one page 'man libunbound'.
7284 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
7286 16 January 2008: Wouter
7287 - incoming queries to the server with TC bit on are replied FORMERR.
7288 - interface-automatic replied the wrong source address on localhost
7289 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
7290 to use ifnum=-1 to mean 'no interface, use kernel route'.
7292 15 January 2008: Wouter
7293 - interface-automatic feature. experimental. Nice for anycast.
7294 - tpkg test for ip6 ancillary data.
7295 - removed debug prints.
7296 - porting experience, define for Solaris, test refined for BSD
7297 compatibility. The feature probably will not work on OpenBSD.
7298 - makedist fixup for ldns-src in build-dir.
7300 14 January 2008: Wouter
7301 - in no debug sets NDEBUG to remove asserts.
7302 - configure --enable-debug is needed for dependency generation
7303 for assertions and for compiler warnings.
7304 - ldns.tgz updated with ldns-trunk (where buffer.h is updated).
7305 - fix lint, unit test in optimize mode.
7306 - default access control allows ::ffff:127.0.0.1 v6mapped localhost.
7308 11 January 2008: Wouter
7309 - man page, warning removed.
7310 - added text describing the use of stub zones for private zones.
7311 - checkconf tests for bad hostnames (IP address), and for doubled
7313 - memory sizes can be given with 'k', 'Kb', or M or G appended.
7315 10 January 2008: Wouter
7316 - typo in example.conf.
7317 - made using ldns-src that is included the package more portable
7318 by linking with .lo instead of .o files in the ldns package.
7319 - nicer do-ip6: yes/no documentation.
7320 - nicer linking of libevent .o files.
7321 - man pages render correctly on solaris.
7323 9 January 2008: Wouter
7324 - fixup openssl RAND problem, when the system is not configured to
7325 give entropy, and the rng needs to be seeded.
7327 8 January 2008: Wouter
7328 - print median and quartiles with extensive logging.
7330 4 January 2008: Wouter
7331 - document misconfiguration in private network.
7333 2 January 2008: Wouter
7334 - fixup typo in requirements.
7335 - document that 'refused' is a better choice than 'drop' for
7336 the access control list, as refused will stop retries.
7338 7 December 2007: Wouter
7339 - unbound-host has a -d option to show what happens. This can help
7340 with debugging (why do I get this answer).
7341 - fixup CNAME handling, on nodata, sets and display canonname.
7342 - dot removed from CNAME display.
7343 - respect -v for NXDOMAINs.
7344 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
7345 - size_t to int for portability of the header file.
7346 - fixup bogus handling.
7347 - dependencies and lint for unbound-host.
7349 6 December 2007: Wouter
7350 - library resolution works in foreground mode, unbound-host app
7352 - unbound-host prints rdata using ldns.
7353 - unbound-host accepts trust anchors, and prints validation
7354 information when you give -v.
7356 5 December 2007: Wouter
7357 - locking in context_new() inside the function.
7358 - setup of libworker.
7360 4 December 2007: Wouter
7361 - minor Makefile fixup.
7362 - moved module-stack code out of daemon/daemon into services/modstack,
7363 preparing for code-reuse.
7364 - move context into own header file.
7365 - context query structure.
7366 - removed unused variable pwd from checkconf.
7367 - removed unused assignment from outside netw.
7368 - check timeval length of string.
7369 - fixup error in val_utils getsigner.
7370 - fixup same (*var) error in netblocktostr.
7371 - fixup memleak on parse error in localzone.
7372 - fixup memleak on packet parse error.
7373 - put ; after union in parser.y.
7374 - small hardening in iter_operate against iq==NULL.
7375 - hardening, if error reply with rcode=0 (noerror) send servfail.
7376 - fixup same (*var) error in find_rrset in msgparse, was harmless.
7377 - check return value of evtimer_add().
7378 - fixup lockorder in lruhash_reclaim(), building up a list of locked
7379 entries one at a time. Instead they are removed and unlocked.
7380 - fptr_wlist for markdelfunc.
7381 - removed is_locked param from lruhash delkeyfunc.
7382 - moved bin_unlock during bin_split purely to please.
7384 3 December 2007: Wouter
7385 - changed checkconf/ to smallapp/ to make room for more support tools.
7386 (such as unbound-host).
7387 - install dirs created with -m 755 because they need to be accessible.
7388 - library extensive featurelist added to TODO.
7389 - please doxygen, lint.
7390 - library test application, with basic functionality.
7391 - fix for building in a subdirectory.
7392 - link lib fix for Leopard.
7394 30 November 2007: Wouter
7395 - makefile that creates libunbound.la, basic file or libunbound.a
7396 when creating static executables (no libtool).
7399 29 November 2007: Wouter
7400 - 0.9 public API start.
7402 28 November 2007: Wouter
7403 - Changeup plan for 0.8 - no complication needed, a simple solution
7404 has been chosen for authoritative features.
7405 - you can use single quotes in the config file, so it is possible
7406 to specify TXT records in local data.
7407 - fixup small memory problem in implicit transparent zone creation.
7408 - test for implicit zone creation and multiple RR RRsets local data.
7409 - local-zone nodefault test.
7410 - show testbound testlist on commit.
7411 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
7412 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
7414 - nicer verbosity: 0 and 1 levels.
7415 - lower nonRDquery chance of eliciting wrongly typed validation
7416 requiring message from the cache.
7417 - fix for nonRDquery validation typing; nodata is detected when
7418 SOA record in auth section (all validation-requiring nodata messages
7419 have a SOA record in authority, so this is OK for the validator),
7420 and NS record is needed to be a referral.
7421 - duplicate checking when adding NSECs for a CNAME, and test.
7422 - created svn tag 0.8, after completing testbed tests.
7424 27 November 2007: Wouter
7425 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
7426 - set size of msgparse lookup table to 32, from 1024, so that its size
7427 is below the 2048 regional large size threshold, and does not cause
7428 a call to malloc when a message is parsed.
7429 - update of memstats tool to print number of allocation calls.
7430 This is what is taking time (not space) and indicates the avg size
7431 of the allocations as well. region_alloc stat is removed.
7433 22 November 2007: Wouter
7434 - noted EDNS in-the-middle dropping trouble as a TODO.
7435 At this point theoretical, no user trouble has been reported.
7436 - added all default AS112 zones.
7437 - answers from local zone content.
7438 * positive answer, the rrset in question
7439 * nodata answer (exist, but not that type).
7440 * nxdomain answer (domain does not exist).
7441 * empty-nonterminal answer.
7442 * But not: wildcard, nsec, referral, rrsig, cname/dname,
7443 or additional section processing, NS put in auth.
7444 - test for correct working of static and transparent and couple
7445 of important defaults (localhost, as112, reverses).
7446 Also checks deny and refuse settings.
7447 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
7449 21 November 2007: Wouter
7450 - local zone internal data setup.
7452 20 November 2007: Wouter
7453 - 0.8 - str2list config support for double string config options.
7454 - local-zone and local-data options, config storage and documentation.
7456 19 November 2007: Wouter
7457 - do not downcase NSEC and RRSIG for verification. Follows
7458 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
7459 - fixup leaking unbound daemons at end of tests.
7460 - README file updated.
7461 - nice libevent not found error.
7462 - README talks about gnu make.
7463 - 0.8: unit test for addr_mask and fixups for it.
7464 and unit test for addr_in_common().
7465 - 0.8: access-control config file element.
7466 and unit test rpl replay file.
7467 - 0.8: fixup address reporting from netevent.
7469 16 November 2007: Wouter
7470 - privilege separation is not needed in unbound at this time.
7471 TODO item marked as such.
7472 - created beta-0.7 branch for support.
7473 - tagged 0.7 for beta release.
7474 - moved trunk to 0.8 for 0.8(auth features) development.
7475 - 0.8: access control list setup.
7477 15 November 2007: Wouter
7478 - review fixups from Jelte.
7480 14 November 2007: Wouter
7481 - testbed script does not recreate configure, since its in svn now.
7482 - fixup checkconf test so that it does not test
7483 /etc/unbound/unbound.conf.
7486 13 November 2007: Wouter
7487 - remove debug print.
7488 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
7490 12 November 2007: Wouter
7491 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
7493 - bugreports to unbound-bugs@nlnetlabs.nl
7494 - fixup testbound so it exits cleanly.
7495 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
7497 9 November 2007: Wouter
7498 - took ldns snapshot in repo.
7499 - default config file is /etc/unbound/unbound.conf.
7500 If it doesn't exist, it is installed with the doc/example.conf file.
7501 The file is not deleted on uninstall.
7502 - default listening is not all, but localhost interfaces.
7504 8 November 2007: Wouter
7505 - Fixup chroot and drop user privileges.
7506 - new L root ip address in default hints.
7508 1 November 2007: Wouter
7509 - Fixup of crash on reload, due to anchors in env not NULLed after
7510 dealloc during deinit.
7511 - Fixup of chroot call. Happens after privileges are dropped, so
7512 that checking the passwd entry still works.
7513 - minor touch up of clear() hashtable function.
7514 - VERB_DETAIL prints out what chdir, username, chroot is being done.
7515 - when id numbers run out, caches are cleared, as in design notes.
7516 Tested with a mock setup with very few bits in id, it worked.
7517 - harden-dnssec-stripped: yes is now default. It insists on dnssec
7518 data for trust anchors. Included tests for the feature.
7520 31 October 2007: Wouter
7521 - cache-max-ttl config option.
7522 - building outside sourcedir works again.
7523 - defaults more secure:
7525 chroot: "/etc/unbound"
7526 The operator can override them to be less secure ("") if necessary.
7527 - fix horrible oversight in sorting rrset references in a message,
7528 sort per reference key pointer, not on referencepointer itself.
7529 - pidfile: "/etc/unbound/unbound.pid" is now the default.
7530 - tests changed to reflect the updated default.
7531 - created hashtable clear() function that respects locks.
7533 30 October 2007: Wouter
7534 - fixup assertion failure that relied on compressed names to be
7535 smaller than uncompressed names. A packet from comrite.com was seen
7536 to be compressed to a larger size. Added it as unit test.
7537 - quieter logging at low verbosity level for common tcp messages.
7538 - no greedy TTL update.
7540 23 October 2007: Wouter
7541 - fixup (grand-)parent problem for dnssec-lameness detection.
7542 - fixup tests to do additional section processing for lame replies,
7543 since the detection needs that.
7544 - no longer trust in query section in reply during dnssec lame detect.
7545 - dnssec lameness does not make the server never ever queried, but
7546 non-preferred. If no other servers exist or answer, the dnssec lame
7547 server is used; the fastest dnssec lame server is chosen.
7548 - added test then when trust anchor cannot be primed (nodata), the
7549 insecure mode from unbound works.
7550 - Fixup max queries per thread, any more are dropped.
7552 22 October 2007: Wouter
7553 - added donotquerylocalhost config option. Can be turned off for
7555 - ISO C compat changes.
7556 - detect RA-no-AA lameness, as LAME.
7557 - DNSSEC-lameness detection, as LAME.
7558 See notes in requirements.txt for choices made.
7559 - tests for lameness detection.
7560 - added all to make test target; need unbound for fwd tests.
7561 - testbound does not pollute /etc/unbound.
7563 19 October 2007: Wouter
7564 - added configure (and its files) to svn, so that the trunk is easier
7565 to use. ./configure, config.guess, config.sub, ltmain.sh,
7567 - added yacc/lex generated files, util/configlexer.c,
7568 util/configparser.c util/configparser.h, to svn.
7569 - without lex no attempt to use it.
7570 - unsecure response validation collated into one block.
7571 - remove warning about const cast of cfgfile name.
7572 - outgoing-interfaces can be different from service interfaces.
7573 - ldns-src configure is done during unbound configure and
7574 ldns-src make is done during unbound make, and so inherits the
7575 make arguments from the unbound make invocation.
7576 - nicer error when libevent problem causes instant exit on signal.
7577 - read root hints from a root hint file (like BIND does).
7579 18 October 2007: Wouter
7580 - addresses are logged with errors.
7581 - fixup testcode fake event to remove pending before callback
7582 since the callback may create new pending items.
7583 - tests updated because retries are now in iterator module.
7584 - ldns-testpkts code is checked for differences between unbound
7585 and ldns by makedist.sh.
7586 - ldns trunk from today added in svn repo for fallback in case
7587 no ldns is installed on the system.
7588 make download_ldns refreshes the tarball with ldns svn trunk.
7589 - ldns-src.tar.gz is used if no ldns is found on the system, and
7590 statically linked into unbound.
7591 - start of regional allocator code.
7592 - regional uses less memory and variables, simplified code.
7593 - remove of region-allocator.
7594 - alloc cache keeps a cache of recently released regional blocks,
7596 - make unit test cleanly free memory.
7598 17 October 2007: Wouter
7599 - fixup another cycle detect and ns-addr timeout resolution bug.
7600 This time by refusing delegations from the cache without addresses
7601 when resolving a mandatory-glue nameserver-address for that zone.
7602 We're going to have to ask a TLD server anyway; might as well be
7603 the TLD server for this name. And this resolves a lot of cases where
7604 the other nameserver names lead to cycles or are not available.
7605 - changed random generator from random(3) clone to arc4random wrapped
7606 for thread safety. The random generator is initialised with
7607 entropy from the system.
7608 - fix crash where failure to prime DNSKEY tried to print null pointer
7610 - removed some debug prints, only verb_algo (4) enables them.
7611 - fixup test; new random generator took new paths; such as one
7612 where no scripted answer was available.
7613 - mark insecure RRs as insecure.
7614 - fixup removal of nonsecure items from the additional.
7615 - reduced timeout values to more realistic, 376 msec (262 msec has
7616 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
7617 - server selection failover to next server after timeout (376 msec).
7619 16 October 2007: Wouter
7620 - no malloc in log_hex.
7621 - assertions around system calls.
7622 - protect against gethostname without ending zero.
7623 - ntop output is null terminated by unbound.
7624 - pidfile content null termination
7625 - various snprintf use sizeof(stringbuf) instead of fixed constant.
7626 - changed loopdetect % 8 with & 0x7 since % can become negative for
7627 weird negative input and particular interpretation of integer math.
7628 - dname_pkt_copy checks length of result, to protect result buffers.
7629 prints an error, this should not happen. Bad strings should have
7630 been rejected earlier in the program.
7631 - remove a size_t underflow from msgreply size func.
7633 15 October 2007: Wouter
7635 - fix IP6 TCP, wrong definition check. With test package.
7636 - fixup the fact that the query section was not compressed to,
7637 the code was there but was called by value instead of by reference.
7638 And test for the case, uses xxd and nc.
7639 - more portable ip6 check for sockaddr types.
7641 8 October 2007: Wouter
7642 - --disable-rpath option in configure for 64bit systems with
7643 several dynamic lib dirs.
7645 7 October 2007: Wouter
7646 - fixup tests for no AD bit in non-DO queries.
7647 - test that makes sure AD bit is not set on non-DO query.
7649 6 October 2007: Wouter
7650 - removed logfile open early. It did not have the proper permissions;
7651 it was opened as root instead of the user. And we cannot change user
7652 id yet, since chroot and bind ports need to be done.
7653 - callback checks for event callbacks done from mini_event. Because
7654 of deletions cannot do this from netevent. This means when using
7655 libevent the protection does not work on event-callbacks.
7656 - fixup too small reply (did not zero counts).
7657 - fixup reply no longer AD bit when query without DO bit.
7659 5 October 2007: Wouter
7660 - function pointer whitelist.
7662 4 October 2007: Wouter
7663 - overwrite sensitive random seed value after use.
7664 - switch to logfile very soon if not -d (console attached).
7665 - error messages do not reveal the trustanchor contents.
7666 - start work on function pointer whitelists.
7668 3 October 2007: Wouter
7669 - fix for multiple empty nonterminals, after multiple DSes in the
7671 - mesh checks if modules are looping, and stops them.
7672 - refetch with CNAMEd nameserver address regression test added.
7673 - fixup line count bug in testcode, so testbound prints correct line
7674 number with parse errors.
7675 - unit test for multiple ENT case.
7676 - fix for cname out of validated unsec zone.
7677 - fixup nasty id=0 reuse. Also added assertions to detect its
7678 return (the assertion catches in the existing test cases).
7680 1 October 2007: Wouter
7681 - skip F77, CXX, objC tests in configure step.
7682 - fixup crash in refetch glue after a CNAME.
7683 and protection against similar failures (with error print).
7685 28 September 2007: Wouter
7686 - test case for unbound-checkconf, fixed so it also checks the
7687 interface: statements.
7689 26 September 2007: Wouter
7690 - SIGHUP will reopen the log file.
7691 - Option to log to syslog.
7692 - please lint, fixup tests (that went to syslog on open, oops).
7693 - config check program.
7695 25 September 2007: Wouter
7696 - tests for NSEC3. Fixup bitmap checks for NSEC3.
7697 - positive ANY response needs to check if wildcard expansion, and
7698 check that original data did not exist.
7699 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
7700 delegation, for abuse of child zone apex nsec3.
7701 - create 0.5 release tag.
7703 24 September 2007: Wouter
7704 - do not make test programs by default.
7705 - But 'make test' will perform all of the tests.
7706 - Advertise builtin select libevent alternative when no libevent
7708 - signit can generate NSEC3 hashes, for generating tests.
7709 - multiple nsec3 parameters in message test.
7710 - too high nsec3 iterations becomes insecure test.
7712 21 September 2007: Wouter
7713 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
7714 - fixup testcode lock safety (port FreeBSD).
7715 - removes subscript has type char warnings (port Solaris 9).
7716 - fixup of field with format type to int (port MacOS/X intel).
7717 - added test for infinite loop case in nonRD answer validation.
7718 It was a more general problem, but hard to reproduce. When an
7719 unsigned rrset is being validated and the key fetched, the DS
7720 sequence is followed, but if the final name has no DS, then no
7721 proof is possible - the signature has been stripped off.
7723 20 September 2007: Wouter
7724 - fixup and test for NSEC wildcard with empty nonterminals.
7725 - makedist.sh fixup for svn info.
7726 - acl features request in plan.
7727 - improved DS empty nonterminal handling.
7728 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
7729 proof anyway, which succeeds in ANS failure case.
7730 - striplab protection in case it becomes -1.
7731 - plans for static and blacklist config.
7733 19 September 2007: Wouter
7734 - comments about non-packed usage.
7735 - plan for overload support in 0.6.
7736 - added testbound tests for a failed resolution from the logs
7737 and for failed prime when missing glue.
7738 - fixup so useless delegation points are not returned from the
7739 cache. Also the safety belt is used if priming fails to complete.
7740 - fixup NSEC rdata not to be lowercased, bind compat.
7742 18 September 2007: Wouter
7743 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
7744 - validator prints subtype classification for debug.
7746 17 September 2007: Wouter
7747 - NSEC3 hash cache unit test.
7748 - validator nsec3 nameerror test.
7750 14 September 2007: Wouter
7751 - nsec3 nodata proof, nods proof, wildcard proof.
7752 - nsec3 support for cname chain ending in noerror or nodata.
7753 - validator calls nsec3 proof routines if no NSECs prove anything.
7754 - fixup iterator bug where it stored the answer to a cname under
7755 the wrong qname into the cache. When prepending the cnames, the
7756 qname has to be reset to the original qname.
7758 13 September 2007: Wouter
7759 - nsec3 find matching and covering, ce proof, prove namerror msg.
7761 12 September 2007: Wouter
7762 - fixup of manual page warnings, like for NSD bugreport.
7763 - nsec3 work, config, max iterations, filter, and hash cache.
7765 6 September 2007: Wouter
7766 - fixup to find libevent on mac port install.
7767 - fixup size_t vs unsigned portability in validator/sigcrypt.
7768 - please compiler on different platforms, for unreachable code.
7770 - pthread_rwlock type is optional, in case of old pthread libs.
7772 5 September 2007: Wouter
7773 - cname, name error validator tests.
7774 - logging of qtype ANY works.
7775 - ANY type answers get RRSIG in answer section of replies (but not
7776 in other sections, unless DO bit is on).
7777 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
7778 - DS and noDS referral validation test.
7779 - if you configure many trust anchors, parent trust anchors can
7780 securely deny existence of child trust anchors, if validated.
7781 - not all *.name NSECs are present because a wildcard was matched,
7782 and *.name NSECs can prove nodata for empty nonterminals.
7783 Also, for wildcard name NSECs, check they are not from the parent
7784 zone (for wildcarded zone cuts), and check absence of CNAME bit,
7786 - configure option for memory allocation debugging.
7787 - port configure option for memory allocation to solaris10.
7789 4 September 2007: Wouter

7792 - testbound removes config file from /tmp on failed exit.
7793 - fixup for referral cleanup of the additional section.
7794 - tests for cname, referral validation.
7795 - neater testbound tpkg output.
7796 - DNAMEs no longer match their apex when synthesized from the cache.
7797 - find correct signer name for DNAME responses.
7798 - wildcarded DNAME test and fixup code to detect.
7799 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
7800 So that wildcarded CNAMEs get their NSEC with them to the answer.
7801 - test for a CNAME to a DNAME to a CNAME to an answer, all from
7802 different domains, for key fetching and signature checking of
7805 3 September 2007: Wouter
7806 - Fixed error in iterator that would cause assertion failure in
7807 validator. CNAME to a NXDOMAIN response was collated into a response
7808 with both a CNAME and the NXDOMAIN rcode. Added a test that the
7809 rcode is changed to NOERROR (because of the CNAME).
7810 - timeout on tcp does not lead to spurious leakage detect.
7811 - account memory for name of lame zones, so that memory leakages does
7812 not show lame cache growth as a leakage growth.
7813 - config setting for lameness cache expressed in bytes, instead of
7815 - tool too summarize allocations per code line.
7817 31 August 2007: Wouter
7818 - can read bind trusted-keys { ... }; files, in a compatibility mode.
7819 - iterator should not detach target queries that it still could need.
7820 the protection against multiple outstanding queries is moved to a
7821 current_query num check.
7822 - validator nodata, positive, referral tests.
7823 - dname print can print '*' wildcard.
7825 30 August 2007: Wouter
7826 - fixup override date config option.
7827 - config options to control memory usage.
7828 - caught bad free of un-alloced data in worker_send error case.
7829 - memory accounting for key cache (trust anchors and temporary cache).
7830 - memory accounting fixup for outside network tcp pending waits.
7831 - memory accounting fixup for outside network tcp callbacks.
7832 - memory accounting for iterator fixed storage.
7833 - key cache size and slabs config options.
7834 - lib crypto cleanups at exit.
7836 29 August 2007: Wouter
7837 - test tool to sign rrsets for testing validator with.
7838 - added RSA and DSA test keys, public and private pairs, 512 bits.
7839 - default configuration is with validation enabled.
7840 Only a trust-anchor needs to be configured for DNSSEC to work.
7841 - do not convert to DER for DSA signature verification.
7842 - validator replay test file, for a DS to DNSKEY DSA key prime and
7845 28 August 2007: Wouter
7846 - removed double use for udp buffers, that could fail,
7847 instead performs a malloc to do the backup.
7848 - validator validates referral messages, by validating all the rrsets
7849 and stores the rrsets in the cache. Further referral (nonRD queries)
7850 replies are made from the rrset cache directly. Unless unchecked
7851 rrsets are encountered, there are then validated.
7852 - enforce that signing is done by a parent domain (or same domain).
7853 - adjust TTL downwards if rrset TTL bigger than signature allows.
7854 - permissive mode feature, sets AD bit for secure, but bogus does
7855 not give servfail (bogus is changed into indeterminate).
7856 - optimization of rrset verification. rr canonical sorting is reused,
7857 for the same rrset. canonical rrset image in buffer is reused for
7859 - if the rrset is too big (64k exactly + large owner name) the
7860 canonicalization routine will fail if it does not fit in buffer.
7861 - faster verification for large sigsets.
7862 - verb_detail mode reports validation failures, but not the entire
7863 algorithm for validation. Key prime failures are reported as
7866 27 August 2007: Wouter
7867 - do not garble the edns if a cache answer fails.
7868 - answer norecursive from cache if possible.
7869 - honor clean_additional setting when returning secure non-recursive
7871 - do not store referral in msg cache for nonRD queries.
7872 - store verification status in the rrset cache to speed up future
7874 - mark rrsets indeterminate and insecure if they are found to be so.
7875 and store this in the cache.
7877 24 August 2007: Wouter
7878 - message is bogus if unsecure authority rrsets are present.
7879 - val-clean-additional option, so you can turn it off.
7880 - move rrset verification out of the specific proof types into one
7881 routine. This makes the proof routines prettier.
7882 - fixup cname handling in validator, cname-to-positive and cname-to-
7884 - Do not synthesize DNSKEY and DS responses from the rrset cache if
7885 the rrset is from the additional section. Signatures may have
7886 fallen off the packet, and cause validation failure.
7887 - more verbose signature date errors (with the date attached).
7888 - increased default infrastructure cache size. It is important for
7889 performance, and 1000 entries are only 212k (or a 400 k total cache
7890 size). To 10000 entries (for 2M entries, 4M cache size).
7892 23 August 2007: Wouter
7893 - CNAME handling - move needs_validation to before val_new().
7894 val_new() setups the chase-reply to be an edited copy of the msg.
7895 new classification, and find signer can find for it.
7896 removal of unsigned crap from additional, and query restart for
7898 - refuse to follow wildcarded DNAMEs when validating.
7899 But you can query for qtype ANY, or qtype DNAME and validate that.
7901 22 August 2007: Wouter
7903 - review - use val_error().
7905 21 August 2007: Wouter
7906 - ANY response validation.
7907 - store security status in cache.
7908 - check cache security status and either send the query to be
7909 validated, return the query to client, or send servfail to client.
7910 Sets AD bit on validated replies.
7911 - do not examine security status on an error reply in mesh_done.
7912 - construct DS, DNSKEY messages from rrset cache.
7913 - manual page entry for override-date.
7915 20 August 2007: Wouter
7916 - validate and positive validation, positive wildcard NSEC validation.
7917 - nodata validation, nxdomain validation.
7919 18 August 2007: Wouter
7920 - process DNSKEY response in FINDKEY state.
7922 17 August 2007: Wouter
7923 - work on DS2KE routine.
7924 - val_nsec.c for validator NSEC proofs.
7925 - unit test for NSEC bitmap reading.
7926 - dname iswild and canonical_compare with unit tests.
7928 16 August 2007: Wouter
7930 - latest release libevent 1.3c and 1.3d have threading fixed.
7931 - key entry fixup data pointer and ttl absolute.
7932 - This makes a key-prime succeed in validator, with DS or DNSKEY as
7934 - fixup canonical compare byfield routine, fix bug and also neater.
7935 - fixed iterator response type classification for queries of type
7937 dig ANY gives sometimes NS rrset in AN and NS section, and parser
7938 removes the NS section duplicate. dig NS gives sometimes the NS
7939 in the answer section, as referral.
7940 - validator FINDKEY state.
7942 15 August 2007: Wouter
7943 - crypto calls to verify signatures.
7944 - unit test for rrsig verification.
7946 14 August 2007: Wouter
7947 - default outgoing ports changed to avoid port 2049 by default.
7948 This port is widely blocked by firewalls.
7949 - count infra lameness cache in memory size.
7950 - accounting of memory improved
7951 - outbound entries are allocated in the query region they are for.
7952 - extensive debugging for memory allocations.
7953 - --enable-lock-checks can be used to enable lock checking.
7954 - protect undefs in config.h from autoheaders ministrations.
7955 - print all received udp packets. log hex will print on multiple
7957 - fixed error in parser with backwards rrsig references.
7958 - mark cycle targets for iterator did not have CD flag so failed
7961 13 August 2007: Wouter
7962 - fixup makefile, if lexer is missing give nice error and do not
7963 mess up the dependencies.
7964 - canonical compare routine updated.
7965 - canonical hinfo compare.
7966 - printout list of the queries that the mesh is working on.
7968 10 August 2007: Wouter
7969 - malloc and free overrides that track total allocation and frees.
7970 for memory debugging.
7971 - work on canonical sort.
7973 9 August 2007: Wouter
7974 - canonicalization, signature checks
7975 - dname signature label count and unit test.
7976 - added debug heap size print to memory printout.
7977 - typo fixup in worker.c
7978 - -R needed on solaris.
7979 - validator override option for date check testing.
7981 8 August 2007: Wouter
7982 - ldns _raw routines created (in ldns trunk).
7983 - sigcrypt DS digest routines
7984 - val_utils uses sigcrypt to perform signature cryptography.
7985 - sigcrypt keyset processing
7987 7 August 2007: Wouter
7988 - security status type.
7989 - security status is copied when rdata is equal for rrsets.
7990 - rrset id is updated to invalidate all the message cache entries
7991 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
7993 - val_sigcrypt file for validator signature checks.
7995 6 August 2007: Wouter
7996 - key cache for validator.
7997 - moved isroot and dellabel to own dname routines, with unit test.
7999 3 August 2007: Wouter
8001 - scrubber check section of lame NS set.
8002 - trust anchors can be in config file or read from zone file,
8003 DS and DNSKEY entries.
8004 - unit test trust anchor storage.
8005 - trust anchors converted to packed rrsets.
8006 - key entry definition.
8008 2 August 2007: Wouter
8009 - configure change for latest libevent trunk version (needs -lrt).
8010 - query_done and walk_supers are moved out of module interface.
8011 - fixup delegation point duplicates.
8012 - fixup iterator scrubber; lame NS set is let through the scrubber
8013 so that the classification is lame.
8014 - validator module exists, and does nothing but pass through,
8015 with calling of next module and return.
8018 1 August 2007: Wouter
8019 - set version to 0.5
8020 - module work for module to module interconnections.
8021 - config of modules.
8022 - detect cycle takes flags.
8024 31 July 2007: Wouter
8028 30 July 2007: Wouter
8029 - changed random state init, so that sequential process IDs are not
8030 cancelled out by sequential thread-ids in the random number seed.
8031 - the fwd_three test, which sends three queries to unbound, and
8032 unbound is kept waiting by ldns-testns for 3 seconds, failed
8033 because the retry timeout for default by unbound is 3 seconds too,
8034 it would hit that timeout and fail the test. Changed so that unbound
8035 is kept waiting for 2 seconds instead.
8037 27 July 2007: Wouter
8038 - removed useless -C debug option. It did not work.
8039 - text edit of documentation.
8040 - added doc/CREDITS file, referred to by the manpages.
8043 26 July 2007: Wouter
8044 - cycle detection, for query state dependencies. Will attempt to
8045 circumvent the cycle, but if no other targets available fails.
8046 - unit test for AXFR, IXFR response.
8047 - test for cycle detection.
8049 25 July 2007: Wouter
8050 - testbound read ADDRESS and check it.
8051 - test for version.bind and friends.
8052 - test for iterator chaining through several referrals.
8053 - test and fixup for refetch for glue. Refetch fails if glue
8054 is still not provided.
8056 24 July 2007: Wouter
8057 - Example section in config manual.
8058 - Addr stored for range and moment in replay.
8060 20 July 2007: Wouter
8061 - Check CNAME chain before returning cache entry with CNAMEs.
8062 - Option harden-glue, default is on. It will discard out of zone
8063 data. If disabled, performance is faster, but spoofing attempts
8064 become a possibility. Note that still normalize scrubbing is done,
8065 and that the potentially spoofed data is used for infrastructure
8066 and not returned to the client.
8067 - if glue times out, refetch by asking parent of delegation again.
8068 Much like asking for DS at the parent side.
8069 - TODO items from forgery-resilience draft.
8070 and on memory handling improvements.
8071 - renamed module_event_timeout to module_event_noreply.
8072 - memory reporting code; reports on memory usage after handling
8073 a network packet (not on cache replies).
8075 19 July 2007: Wouter
8076 - shuffle NS selection when getting nameserver target addresses.
8077 - fixup of deadlock warnings, yield cpu in checklock code so that
8078 freebsd scheduler selects correct process to run.
8079 - added identity and version config options and replies.
8080 - store cname messages complete answers.
8082 18 July 2007: Wouter
8083 - do not query addresses, 127.0.0.1, and ::1 by default.
8085 17 July 2007: Wouter
8086 - forward zone options in config file.
8087 - forward per zone in iterator. takes precedence over stubs.
8088 - fixup commithooks.
8089 - removed forward-to and forward-to-port features, subsumed by
8091 - fix parser to handle absent server: clause.
8092 - change untrusted rrset test to account for scrubber that is now
8093 applied during the test (which removes the poison, by the way).
8094 - feature, addresses can be specified with @portnumber, like nsd.conf.
8095 - test config files changed over to new forwarder syntax.
8097 27 June 2007: Wouter
8098 - delete of mesh does a postorder traverse of the tree.
8099 - found and fixed a memory leak. For TTL=0 messages, that would
8100 not be cached, instead the msg-replyinfo structure was leaked.
8101 - changed server selection so it will filter out hosts that are
8102 unresponsive. This is defined as a host with the maximum rto value.
8103 This means that unbound tried the host for retries up to 120 secs.
8104 The rto value will time out after host-ttl seconds from the cache.
8105 This keeps such unresolvable queries from taking up resources.
8106 - utility for keeping histogram.
8108 26 June 2007: Wouter
8109 - mesh is called by worker, and iterator uses it.
8110 This removes the hierarchical code.
8111 QueryTargets state and Finished state are merged for iterator.
8112 - forwarder mode no longer sets AA bit on first reply.
8113 - rcode in walk_supers is not needed.
8115 25 June 2007: Wouter
8117 - error encode routine for ease.
8119 22 June 2007: Wouter
8120 - removed unused _node iterator value from rbtree_t. Takes up space.
8121 - iterator can handle querytargets state without a delegation point
8122 set, so that a priming(stub) subquery error can be handled.
8123 - iterator stores if it is priming or not.
8124 - log_query_info() neater logging.
8125 - changed iterator so that it does not alter module_qstate.qinfo
8126 but keeps a chase query info. Also query_flags are not altered,
8127 the iterator uses chase_flags.
8128 - fixup crash in case no ports for the family exist.
8130 21 June 2007: Wouter
8131 - Fixup secondary buffer in case of error callback.
8132 - cleanup slumber list of runnable states.
8133 - module_subreq_depth fails to work in slumber list.
8134 - fixup query release for cached results to sub targets.
8135 - neater error for tcp connection failure, shows addr in verbose.
8136 - rbtree_init so that it can be used with preallocated memory.
8138 20 June 2007: Wouter
8139 - new -C option to enable coredumps after forking away.
8141 - fixup CNAME generation by scrubber, and memory allocation of it.
8142 - fixup deletion of serviced queries when all callbacks delete too.
8143 - set num target queries to 0 when you move them to slumber list.
8144 - typo in check caused subquery errors to be ignored, fixed.
8145 - make lint happy about rlim_t.
8146 - freeup of modules after freeup of module-states.
8147 - duplicate replies work, this uses secondary udp buffer in outnet.
8149 19 June 2007: Wouter
8150 - nicer layout in stats.c, review 0.3 change.
8151 - spelling improvement, review 0.3 change.
8152 - uncapped timeout for server selection, so that very fast or slow
8153 servers will stand out from the rest.
8154 - target-fetch-policy: "3 2 1 0 0" config setting.
8155 - fixup queries answered without RD bit (for root prime results).
8156 - refuse AXFR and IXFR requests.
8157 - fixup RD flag in error reply from iterator. fixup RA flag from
8159 - fixup encoding of very short edns buffer sizes, now sets TC bit.
8160 - config options harden-short-bufsize and harden-large-queries.
8162 18 June 2007: Wouter
8163 - same, move subqueries to slumber list when first has resolved.
8164 - fixup last fix for duplicate callbacks.
8165 - another offbyone in targetcounter. Also in Java prototype by the way.
8167 15 June 2007: Wouter
8168 - if a query asks to be notified of the same serviced query result
8169 multiple times, this will succeed. Only one callback will happen;
8170 multiple outbound-list entries result (but the double cleanup of it
8172 - when iterator moves on due to CNAME or referral, it will remove
8173 the subqueries (for other targets). These are put on the slumber
8175 - state module wait subq is OK with no new subqs, an old one may have
8176 stopped, with an error, and it is still waiting for other ones.
8177 - if a query loops, halt entire query (easy way to clean up properly).
8179 14 June 2007: Wouter
8180 - num query targets was > 0 , not >= 0 compared, so that fetch
8181 policy of 0 did nothing.
8183 13 June 2007: Wouter
8184 - debug option: configure --enable-static-exe for compile where
8185 ldns and libevent are linked statically. Default is off.
8186 - make install and make uninstall. Works with static-exe and without.
8187 installation of unbound binary and manual pages.
8188 - alignment problem fix on solaris 64.
8189 - fixup address in case of TCP error.
8191 12 June 2007: Wouter
8192 - num target queries was set to 0 at a bad time. Default it to 0 and
8193 increase as target queries are done.
8194 - synthesize CNAME and DNAME responses from the cache.
8195 - Updated doxygen config for doxygen 1.5.
8196 - aclocal newer version.
8197 - doxygen 1.5 fixes for comments (for the strict check on docs).
8199 11 June 2007: Wouter
8200 - replies on TCP queries have the address field set in replyinfo,
8201 for serviced queries, because the initiator does not know that
8202 a TCP fallback has occured.
8203 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
8204 if qtype directly queries for the type (and then only show that
8205 'unknown type' in the answer section).
8206 - fixed message parsing where rrsigs on their own would be put
8207 in the signature list over the rrsig type.
8210 - fixup error in double linked list insertion for subqueries and
8211 for outbound list of serviced queries for iterator module.
8212 - nicer printout of outgoing port selection.
8213 - fixup cname target readout.
8214 - nicer debug output.
8215 - fixup rrset counts when prepending CNAMEs to the answer.
8216 - fixup rrset TTL for prepended CNAMEs.
8217 - process better check for looping modules, and which submodule to
8219 - subreq insertion code fixup for slumber list.
8220 - VERB_DETAIL, verbosity: 2 level gives short but readable output.
8221 VERB_ALGO, verbosity: 3 gives extensive output.
8222 - fixup RA bit in cached replies.
8223 - fixup CNAME responses from the cache no longer partial response.
8224 - error in network send handled without leakage.
8225 - enable ip6 from config, and try ip6 addresses if available,
8226 if ip6 is not connected, skips to next server.
8229 - iterator state finished.
8230 - subrequests without parent store in cache and stop.
8231 - worker slumber list for ongoing promiscuous queries.
8232 - subrequest error handling.
8233 - priming failure returns SERVFAIL.
8234 - priming gives LAME result, returns SERVFAIL.
8235 - debug routine to print dns_msg as handled by iterator.
8236 - memleak in config file stubs fixup.
8237 - more small bugs, in scrubber, query compare no ID for lookup,
8238 in dname validation for NS targets.
8239 - sets entry.key for new special allocs.
8240 - lognametypeclass can display unknown types and classes.
8243 - random selection of equally preferred nameserver targets.
8244 - reply info copy routine. Reuses existing code.
8245 - cache lameness in response handling.
8246 - do not touch qstate after worker_process_query because it may have
8247 been deleted by that routine.
8248 - Prime response state.
8249 - Process target response state.
8250 - some memcmp changed to dname_compare for case preservation.
8253 - normalize incoming messages. Like unbound-java, with CNAME chain

8405 - decompress query section, extremely lenient acceptance.
8406 But only for answers from other servers, not for plain queries.
8407 - compression and decompression test cases.
8409 - example.conf interface: line is changed from 127.0.0.1 which leads
8410 to problems if used (restricting communication to the localhost),

8636 This makes all threads service incoming requests, instead of one.
8637 No memory is leaking during reloads, service of queries, etc.
8638 - test that uses ldns-testns -f to test threading. Have to answer
8639 three queries at the same time.
