1091 11 September 2018: Wouter
1092 - Fixed unused return value warnings in contrib/fastrpz.patch for
1094 - Fix to squelch respip warning in unit test, it is printed at

1099 10 September 2018: Wouter
1100 - 1.8.1 in svn trunk. (changes from 4,5,.. sep apply).

1122 - Disable minimal-responses in ipsecmod unit tests.
1123 - Added serve-expired-ttl and serve-expired-ttl-reset options.
1125 27 August 2018: Wouter
1126 - Set defaults to yes for a number of options to increase speed and
1127 resilience of the server. The so-reuseport, harden-below-nxdomain,
1128 and minimal-responses options are enabled by default. They used
1129 to be disabled by default, waiting to make sure they worked. They
1130 are enabled by default now, and can be disabled explicitly by
1131 setting them to "no" in the unbound.conf config file. The reuseport
1132 and minimal options increases speed of the server, and should be
1133 otherwise harmless. The harden-below-nxdomain option works well
1134 together with the recently default enabled qname minimisation, this
1135 causes more fetches to use information from the cache.
1136 - next release is called 1.8.0.
1137 - Fix lintflags for lint on FreeBSD.

1158 - Set libunbound to increase current, because the libunbound change
1159 to the event callback function signature. That needs programs,
1160 that use it, to recompile against the new header definition.
1161 - print servfail info to log as error.
1162 - added more servfail printout statements, to the iterator.
1163 - log-servfail: yes prints log lines that say why queries are

1831 - [dnscrypt] prevent dnscrypt-secret-key, dnscrypt-provider-cert
1833 - [dnscrypt] introduce dnscrypt-provider-cert-rotated option,
1835 This option allows handling multiple cert/key pairs while only
1836 distributing some of them.
1837 In order to reliably match a client magic with a given key without
1838 strong assumption as to how those were generated, we need both key and
1839 cert. Likewise, in order to know which ES version should be used.
1840 On the other hand, when rotating a cert, it can be desirable to only
1841 serve the new cert but still be able to handle clients that are still
1842 using the old certs's public key.
1843 The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not
1844 publish the cert as part of the DNS's provider_name's TXT answer.

3377 - RFC 7553 RR type URI support, is now enabled by default.
3380 - Fix #674: Do not free pointers given by getenv.
3383 - Fix that unparseable error responses are ratelimited.

3388 - Document that ratelimit works with unbound-control set_option.
3391 - iana portlist update.
3392 - documentation proposes ratelimit of 1000 (closer to what upstream
3393 servers expect from us).
3396 - DLV is going to be decommissioned. Advice to stop using it, and
3397 put text in the example configuration and man page to that effect.
3400 - Change syntax of particular validator error to be easier for
3401 machine parse, swap rrset and ip adres info so it looks like:
3402 validation failure <www.example.nl. TXT IN>: signature crypto
3403 failed from 2001:DB8:7:bba4::53 for <*.example.nl. NSEC IN>
3406 - caps-whitelist in unbound.conf allows whitelist of loadbalancers
3407 that cannot work with caps-for-id or its fallback.

3422 16 April 2015: Wouter
3423 - Add local-zone type inform_deny, that logs query and drops answer.

3425 is default 10. Repeated normal queries get resolved and with
3426 prefetch stay in the cache.
3427 - Fix bug#664: libunbound python3 related fixes (from Tomas Hozza)
3428 Use print_function also for Python2.

3445 7 April 2015: Wouter
3446 - Libunbound skips dos-line-endings from etc/hosts.
3447 - Unbound exits with a fatal error when the auto-trust-anchor-file
3448 fails to be writable. This is seconds after startup. You can
3449 load a readonly auto-trust-anchor-file with trust-anchor-file.
3450 The file has to be writable to notice the trust anchor change,
3451 without it, a trust anchor change will be unnoticed and the system
3452 will then become inoperable.
3453 - unbound-control list_insecure command shows the negative trust
3454 anchors currently configured, patch from Jelte Jansen.

3509 - Patch from Brad Smith that syncs compat/getentropy_linux with
3510 OpenBSD's version (2015-03-04).
3511 - 0x20 fallback improved: servfail responses do not count as missing
3512 comparisons (except if all responses are errors),
3513 inability to find nameservers does not fail equality comparisons,
3514 many nameservers does not try to compare more than max-sent-count,
3515 parse failures start 0x20 fallback procedure.
3516 - store caps_response with best response in case downgrade response
3517 happens to be the last one.
3518 - Document windows 8 tests.

3877 fixes from FreeBSD's copy of Unbound, he notes:
3878 Generate unbound-control-setup.sh at build time so it respects
3879 prefix and sysconfdir from the configure script. Also fix the
3880 umask to match the comment, and the comment to match the umask.
3881 Add const and static where needed. Use unions instead of
3882 playing pointer poker. Move declarations that are needed in
3883 multiple source files into a shared header. Move sldns_bgetc()
3884 from parse.c to buffer.c where it belongs. Introduce a new
3885 header file, worker.h, which declares the callbacks that
3886 all workers must define. Remove those declarations from
3887 libworker.h. Include the correct headers in the correct places.
3888 Fix a few dummy callbacks that don't match their prototype.
3889 Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK.
3890 Remove a useless printf which breaks reproducible builds.
3891 Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
3892 no longer used. Add unbound-control-setup.sh to the list of
3893 generated files. The prototype for libworker_event_done_cb()
3894 needs to be moved from libunbound/libworker.h to
3895 libunbound/worker.h.
3896 - Fixup out-of-directory compile with unbound-control-setup.sh.in.
3900 - unbound-host -D enabled dnssec and reads root trust anchor from

3938 23 April 2014: Wouter
3939 - Patch from Jeremie Courreges-Anglas to use arc4random_uniform

3943 - Fix compile with libevent2 on FreeBSD.
3945 11 April 2014: Wouter
3946 - Fix #502: explain that do-ip6 disable does not stop AAAA lookups,

3948 - iana portlist updated.
3950 10 April 2014: Wouter
3951 - iana portlist updated.
3952 - Patch from Hannes Frederic Sowa for Linux 3.15 fragmentation

3965 on the same log-line as the error.
3967 8 April 2014: Wouter
3968 - Fix #574: make test fails on Ubuntu 14.04. Disabled remote-control

3999 - iana portlist updated.
4001 20 February 2014: Matthijs
4002 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
4003 received. This is okay according 4035, but not after revising
4004 existence in 4592. NSEC empty non-terminals exist and thus the
4005 RCODE should have been NOERROR. If this occurs, and the RRsets
4006 are secure, we set the RCODE to NOERROR and the security status
4007 of the response is also considered secure.
4009 14 February 2014: Wouter
4010 - Works on Minix (3.2.1).
4012 11 February 2014: Wouter

4042 - fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
4045 30 January 2014: Wouter
4046 - delay-close does not act if there are udp-wait queries, so that
4047 it does not make a socketdrain DoS easier.
4049 28 January 2014: Wouter
4050 - iana portlist updated.
4051 - iana portlist test updated so it does not touch the source
4052 if there are no changes.
4053 - delay-close: msec option that delays closing ports for which
4054 the UDP reply has timed out. Keeps the port open, only accepts
4055 the correct reply. This correct reply is not used, but the port
4056 is open so that no port-denied ICMPs are generated.
4058 27 January 2014: Wouter
4059 - reuseport is attempted, then fallback to without on failure.
4061 24 January 2014: Wouter
4062 - Change unbound-event.h to use void* buffer, length idiom.
4063 - iana portlist updated.
4064 - unbound-event.h is installed if you configure --enable-event-api.
4065 - speed up unbound (reports say it could be up to 10%), by reducing
4066 lock contention on localzones.lock. It is changed to an rwlock.
4067 - so-reuseport: yesno option to distribute queries evenly over
4068 threads on Linux (Thanks Robert Edmonds).
4071 21 January 2014: Wouter
4072 - Fix #547: no trustanchor written if filesystem full, fclose checked.

4096 linking with libldns that uses global variables ldns_ .
4099 - Fix bug#537: compile python plugin without ldns library.
4102 - Fix bug#536: acl_deny_non_local and refuse_non_local added.
4105 - Patch from Neel Goyal to fix async id assignment if callback
4106 is called by libunbound in the mesh attach.

4108 consistency with nsd.conf syntax.
4111 - Patch from Neel Goyal to fix callback in libunbound.
4114 - if configured --with-libunbound-only fix make install.

4118 more specific interface port 53 can be used at the same time, and
4119 one of the daemons is unbound.
4120 - iana portlist update.
4121 - separate ldns into core ldns inside ldns/ subdirectory. No more
4122 --with-ldns is needed and unbound does not rely on libldns.
4123 - portability fixes for new USE_SLDNS ldns subdir codebase.
4126 - Patch from Neel Goyal: Add an API call to set an event base on an
4127 existing ub_ctx. This basically just destroys the current worker and
4128 sets the event base to the current. And fix a deadlock in
4129 ub_resolve_event – the cfglock is held when libworker_create is
4130 called. This ends up trying to acquire the lock again in
4131 context_obtain_alloc in the call chain.
4132 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
4135 - unbound-event.h is installed if configured --with-libevent. It
4136 contains low-level library calls, that use libevent's event_base
4137 and an ldns_buffer for the wire return packet to perform async
4138 resolution in the client's eventloop.
4141 - 1.4.21 tag created.

4205 - Fixup manpage syntax.
4208 - get_option and set_option support for log-time-ascii, python-script
4209 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
4210 immediately. The others are mostly useful for libunbound users.
4213 - get_option, set_option, unbound-checkconf -o and libunbound
4214 getoption and setoption support cache-min-ttl and cache-max-ttl.
4217 - Fix#501: forward-first does not recurse, when forward name is ".".
4218 - iana portlist update.
4219 - Max include depth is unlimited.
4222 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply
4223 patch to it to not fail when -Werror is also specified, from the
4225 - iana portlist update.

4540 19 June 2012: Wouter
4541 - --with-libunbound-only build option, only builds the library and
4542 not the daemon and other tools.
4544 18 June 2012: Wouter
4547 15 June 2012: Wouter
4548 - implement log-time-ascii on windows.

4616 - new approach to NS fetches for DS lookup that works with
4617 cornercases, and is more robust and considers forwarders.
4619 19 March 2012: Wouter
4620 - iana portlist updated.
4621 - fix to locate nameservers for DS lookup with NS fetches.
4623 16 March 2012: Wouter
4624 - Patch for access to full DNS packet data in unbound python module
4627 9 March 2012: Wouter
4628 - Applied line-buffer patch from Augie Schwer to validation.reporter.sh.
4630 2 March 2012: Wouter
4631 - flush_infra cleans timeouted servers from the cache too.
4632 - removed warning from --enable-ecdsa.
4634 1 March 2012: Wouter
4635 - forward-first option. Tries without forward if a query fails.
4636 Also stub-first option that is similar.

4644 for unbound-control.exe, and unbound-checkconf.exe.
4646 23 February 2012: Wouter
4647 - Fix to squelch 'network unreachable' errors from tcp connect in
4648 logs, high verbosity will show them.
4650 16 February 2012: Wouter
4651 - iter_hints is now thread-owned in module env, and thus threadsafe.
4652 - Fix prefetch and sticky NS, now the prefetch works. It picks
4653 nameservers that 'would be valid in the future', and if this makes
4654 the NS timeout, it updates that NS by asking delegation from the
4655 parent again. If child NS has longer TTL, that TTL does not get
4656 refreshed from the lookup to the child nameserver.
4658 15 February 2012: Wouter
4659 - Fix forward-zone memory, uses malloc and frees original root dp.
4660 - iter hints (stubs) uses malloc inside for more dynamicity.
4661 - unbound-control forward_add, forward_remove, stub_add, stub_remove
4662 can modify stubs and forwards for running unbound (on mobile computer)
4663 they can also add and remove domain-insecure for the zone.
4665 14 February 2012: Wouter
4666 - Fix sticky NS (ghost domain problem) if prefetch is yes.
4667 - iter forwards uses malloc inside for more dynamicity.
4669 13 February 2012: Wouter
4670 - RT#2955. Fix for cygwin compilation.
4671 - iana portlist updated.
4673 10 February 2012: Wouter
4674 - Slightly smaller critical region in one case in infra cache.
4675 - Fix timeouts to keep track of query type, A, AAAA and other, if
4676 another has caused timeout blacklist, different type can still probe.
4677 - unit test fix for nomem_cnametopos.rpl race condition.
4679 9 February 2012: Wouter
4680 - Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
4682 8 February 2012: Wouter
4683 - implement draft-ietf-dnsext-ecdsa-04; which is in IETF LC; This
4684 implementation is experimental at this time and not recommended
4685 for use on the public internet (the protocol numbers have not
4686 been assigned). Needs recent ldns with --enable-ecdsa.
4687 - fix memory leak in errorcase for DSA signatures.
4688 - iana portlist updated.
4689 - workaround for openssl 0.9.8 ecdsa sha2 and evp problem.

4696 - svn trunk is 1.4.17 in development.
4697 - iana portlist updated.
4699 1 February 2012: Wouter
4700 - Fix validation failures (like: validation failure xx: no NSEC3
4701 closest encloser from yy for DS zz. while building chain of trust,
4702 because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
4703 for an NSEC3. Now it does not change rdata, and fixes TTL.
4705 30 January 2012: Wouter
4706 - Fix version-number in libtool to be version-info so it produces
4707 libunbound.so.2 like it should.
4709 26 January 2012: Wouter
4710 - Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.

4716 - Fix memset in test code.
4718 20 January 2012: Wouter
4719 - Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
4721 19 January 2012: Wouter
4722 - Fix to write key files completely to a temporary file, and if that
4723 succeeds, replace the real key file. So failures leave a useful file.
4725 18 January 2012: Wouter
4726 - tag 1.4.15rc1 created
4727 - updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
4729 17 January 2012: Wouter
4730 - Fix bug where canonical_compare of RRSIG did not downcase the
4731 signer-name. This is mostly harmless because RRSIGs do not have
4732 to be sorted in canonical order, usually.
4734 12 January 2012: Wouter
4735 - bug#428: add ub_version() call to libunbound. API version increase,
4736 with (binary) backwards compatibility for the previous version.
4738 10 January 2012: Wouter
4739 - Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
4740 that would be permissible by the RFCs but it is not the TTL in the
4742 - iana portlist updated.
4743 - uninitialised variable in reprobe for rtt blocked domains fixed.
4744 - lintfix and new flex output.
4746 2 January 2012: Wouter
4747 - Fix to randomize hash function, based on 28c3 congress, reported
4750 24 December 2011: Wouter
4751 - Fix for memory leak (about 20 bytes when a tcp or udp send operation
4752 towards authority servers failed, takes about 50.000 such failures to
4753 leak one Mb, such failures are also usually logged), reported by
4755 - iana portlist updated.
4757 19 December 2011: Wouter
4758 - Fix for VU#209659 CVE-2011-4528: Unbound denial of service
4759 vulnerabilities from nonstandard redirection and denial of existence
4760 http://www.unbound.net/downloads/CVE-2011-4528.txt

4773 - Fix to constrain signer_name to be a parent of the lookupname.
4775 5 December 2011: Wouter
4776 - Fix getaddrinfowithincludes on windows with fedora16 mingw32-gcc.
4777 - Fix warnings with gcc 4.6 in compat/inet_ntop.c.
4778 - Fix warning unused in compat/strptime.c.

4784 30 November 2011: Wouter
4785 - Fix for tcp-upstream and ssl-upstream for if a laptop sleeps, causes
4786 SERVFAILs. Also fixed for UDP (but less likely).
4788 28 November 2011: Wouter
4789 - Fix quartile time estimate, it was too low, (thanks Jan Komissar).
4790 - iana ports updated.
4792 11 November 2011: Wouter
4793 - Makefile compat with SunOS make, BSD make and GNU make.

4811 - documentation for new options: ssl-upstream, ssl-service-key and
4813 - iana portlist updated.
4814 - fix -flto detection on Lion for llvm-gcc.
4816 31 October 2011: Wouter
4817 - dns over ssl support, ssl-service-pem and ssl-service-key files
4818 can be given and then TCP queries are serviced wrapped in SSL.
4820 27 October 2011: Wouter
4821 - lame-ttl and lame-size options no longer exist, it is integrated
4822 with the host info. They are ignored (with verbose warning) if
4823 encountered to keep the config file backwards compatible.
4824 - fix iana-update for changing gzip compression of results.
4825 - fix export-all-symbols on OSX.
4827 26 October 2011: Wouter

4833 24 October 2011: Wouter
4834 - Fix resolve of partners.extranet.microsoft.com with a fix for the
4835 server selection for choosing out of a (particular) list of bad
4837 - Fix make_new_space function so that the incoming query is not
4838 overwritten if a jostled out query causes a waiting query to be
4839 resumed that then fails and sends an error message. (Thanks to
4842 21 October 2011: Wouter
4843 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
4844 option enabled because of memory layout exe vs dll.
4846 19 October 2011: Wouter
4847 - fix unbound-anchor for broken strptime on OSX lion, detected
4849 - Detect if GOST really works, openssl1.0 on OSX fails.
4850 - Implement ipv6%interface notation for scope_id usage.
4852 17 October 2011: Wouter
4853 - better documentation for inform_super (Thanks Yang Zhe).
4855 14 October 2011: Wouter
4856 - Fix for out-of-memory condition in libunbound (thanks
4859 13 October 2011: Wouter
4860 - Fix --enable-allsymbols, it depended on link specifics of the
4861 target platform, or fptr_wlist assertion failures could occur.
4863 12 October 2011: Wouter
4864 - updated contrib/unbound_munin_ to family=auto so that it works with
4865 munin-node-configure automatically (if installed as
4866 /usr/local/share/munin/plugins/unbound_munin_ ).
4868 27 September 2011: Wouter
4869 - unbound.exe -w windows option for start and stop service.
4871 23 September 2011: Wouter
4872 - TCP-upstream calculates tcp-ping so server selection works if there
4875 20 September 2011: Wouter
4876 - Fix classification of NS set in answer section, where there is a
4877 parent-child server, and the answer has the AA flag for dir.slb.com.
4878 Thanks to Amanda Constant from Secure64.
4880 16 September 2011: Wouter
4881 - fix bug #408: accept patch from Steve Snyder that comments out
4882 unused functions in lookup3.c.
4883 - iana portlist updated.
4884 - fix EDNS1480 change memleak and TCP fallback.
4885 - fix various compiler warnings (reported by Paul Wouters).
4886 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
4887 fetch if sentcount > 3, stop query if sentcount > 16. Count is
4888 reset when referral or CNAME happens. This makes unbound better
4889 at managing large NS sets, they are explored when there is continued
4890 interest (in the form of queries).
4892 15 September 2011: Wouter
4894 - trunk contains 1.4.14 in development.
4895 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
4897 12 September 2011: Wouter
4898 - Reverted dns EDNS backoff fix, it did not help and needs
4899 fragmentation fixes instead.
4902 7 September 2011: Wouter
4903 - Fix operation in ipv6 only (do-ip4: no) mode.
4905 6 September 2011: Wouter
4906 - fedora specfile updated.
4908 5 September 2011: Wouter
4911 2 September 2011: Wouter
4912 - iana portlist updated.
4914 26 August 2011: Wouter
4915 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
4916 - Fix validation failures due to EDNS backoff retries, the retry
4917 for fetch of data has want_dnssec because the iter_indicate_dnssec
4918 function returns true when validation failure retry happens, and
4919 then the serviced query code does not fallback to noEDNS, even if
4920 the cache says it has this. This helps for DLV deployment when
4921 the DNSSEC status is not known for sure before the lookup concludes.
4923 24 August 2011: Wouter
4924 - Applied patch from Karel Slany that fixes a memory leak in the
4925 unbound python module, in string conversions.
4927 22 August 2011: Wouter
4928 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
4929 Zhang and Luo Ce). Unbound responds with the RR types that are
4930 available at the name for qtype ANY and validates those RR types.
4931 It does not test for completeness (i.e. with NSEC or NSEC3 query),
4932 and it does not follow the CNAME or DNAME to another name (with
4933 even more data for the already large response).
4934 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
4935 - Documented the options that work with control set_option command.
4936 - tcp-upstream yes/no option (works with set_option) for tunnels.
4938 18 August 2011: Wouter
4939 - fix autoconf call in makedist crosscompile to RC or snapshot.
4941 17 August 2011: Wouter

4944 - iana portlist updated.
4946 10 August 2011: Wouter
4947 - Fix python site-packages path to /usr/lib64.
4948 - updated patch from Tom.

4957 1 August 2011: Wouter
4958 - Fix autoconf 2.68 warnings
4960 14 July 2011: Wouter
4961 - Unbound implements RFC6303 (since version 1.4.7).
4962 - tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the

4964 - iana portlist updated.
4966 13 July 2011: Wouter
4967 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
4969 11 July 2011: Wouter
4970 - Fix wildcard expansion no-data reply under an optout NSEC3 zone is
4971 validated as insecure, reported by Jia Li (lijia@cnnic.cn).
4974 - 1.4.12rc1 tag created.
4977 - version number in example config file.
4978 - fix that --enable-static-exe does not complain about it unknown.
4980 30 June 2011: Wouter
4981 - tag relase 1.4.11, trunk is 1.4.12 development.
4982 - iana portlist updated.
4983 - fix bug#395: id bits of other query may leak out under conditions
4984 - fix replyaddr count wrong after jostled queries, which leads to
4985 eventual starvation where the daemon has no replyaddrs left to use.
4986 - fix comment about rndc port, that referred to the old port number.
4987 - fix that the listening socket is not closed when too many remote
4988 control connections are made at the same time.
4989 - removed ldns-src tarball inside the unbound tarball.
4991 23 June 2011: Wouter
4992 - Changed -flto check to support clang compiler.
4993 - tag 1.4.11rc3 created.
4995 17 June 2011: Wouter
4996 - tag 1.4.11rc1 created.
4997 - remove warning about signed/unsigned from flex (other flex version).
4998 - updated aclocal.m4 and libtool to match.
4999 - tag 1.4.11rc2 created.
5001 16 June 2011: Wouter
5002 - log-queries: yesno option, default is no, prints querylog.
5003 - version is 1.4.11.
5005 14 June 2011: Wouter
5006 - Use -flto compiler flag for link time optimization, if supported.
5007 - iana portlist updated.
5009 12 June 2011: Wouter
5010 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
5012 10 June 2011: Wouter
5013 - unbound-control has version number in the header,
5014 UBCT[version]_space_ is the header sent by the client now.
5015 - Unbound control port number is registered with IANA:
5016 ub-dns-control 8953/tcp unbound dns nameserver control
5017 This is the new default for the control-port config setting.
5018 - statistics-interval prints the number of jostled queries to log.
5021 - Fix Makefile for U in environment, since wrong U is more common than
5022 deansification necessity.
5023 - iana portlist updated.
5024 - updated ldns tarball to 1.6.10rc2 snapshot of today.
5027 - Fix assertion failure when unbound generates an empty error reply
5028 in response to a query, CVE-2011-1922 VU#531342.
5029 - This fix is in tag 1.4.10.
5030 - defense in depth against the above bug, an error is printed to log
5031 instead of an assertion failure.
5034 - bug#386: --enable-allsymbols option links all binaries to libunbound
5035 and reduces install size significantly.
5036 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
5037 - iana portlist updated.
5038 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
5040 14 April 2011: Wouter
5041 - configure created with newer autoconf 2.66.
5043 12 April 2011: Wouter
5044 - bug#378: Fix that configure checks for ldns_get_random presence.
5046 8 April 2011: Wouter
5047 - iana portlist updated.
5048 - queries with CD flag set cause DNSSEC validation, but the answer is
5049 not withheld if it is bogus. Thus, unbound will retry if it is bad
5050 and curb the TTL if it is bad, thus protecting the cache for use by
5051 downstream validators.
5052 - val-override-date: -1 ignores dates entirely, for NTP usage.
5054 29 March 2011: Wouter
5055 - harden-below-nxdomain: changed so that it activates when the
5056 cached nxdomain is dnssec secure. This avoids backwards
5057 incompatibility because those old servers do not have dnssec.
5059 24 March 2011: Wouter
5060 - iana portlist updated.
5064 17 March 2011: Wouter
5065 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
5066 Applied but did not do the --disable-gost.
5068 10 March 2011: Wouter
5069 - tag 1.4.9 release candidate 1 created.
5071 3 March 2011: Wouter
5072 - updated ldns to today.
5074 1 March 2011: Wouter
5075 - Fix no ADflag for NXDOMAIN in NSEC3 optout. And wildcard in optout.

5094 11 February 2011: Wouter
5095 - iana portlist updated.
5096 - tpkg updated with common.sh for common functionality.
5098 7 February 2011: Wouter
5099 - Added regression test for addition of a .net DS to the root, and
5100 cache effects with different TTL for glue and DNSKEY.
5101 - iana portlist updated.
5103 28 January 2011: Wouter
5104 - Fix remove private address does not throw away entire response.
5106 24 January 2011: Wouter
5109 19 January 2011: Wouter
5110 - fix bug#349: no -L/usr for ldns.
5112 18 January 2011: Wouter
5113 - ldns 1.6.8 tarball included.
5116 17 January 2011: Wouter

5118 - iana portlist updated.
5120 14 January 2011: Wouter
5121 - Fix so a changed NS RRset does not get moved name stuck on old
5122 server, for type NS the TTL is not increased.
5124 13 January 2011: Wouter
5125 - Fix prefetch so it does not get stuck on old server for moved names.
5127 12 January 2011: Wouter
5128 - iana portlist updated.
5130 11 January 2011: Wouter
5131 - Fix insecure CNAME sequence marked as secure, reported by Bert

5139 - iana portlist updated.
5141 23 December 2010: Wouter
5142 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
5144 21 December 2010: Wouter
5145 - algorithm compromise protection using the algorithms signalled in
5146 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
5147 and thus, if you have multiple algorithms in your trust-anchor-file
5148 then it will now behave different than before. Also, 5011 rollover
5149 for algorithms needs to be double-signature until the old algorithm
5151 It is not an option, because I see no use to turn the security off.
5152 - iana portlist updated.
5154 17 December 2010: Wouter
5155 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
5156 - fix validation in this case: CNAME to nodata for co-hosted opt-in
5157 NSEC3 insecure delegation, was bogus, fixed to be insecure.
5159 16 December 2010: Wouter

5174 - iana portlist updated.
5176 18 November 2010: Wouter
5177 - harden-below-nxdomain option, default off (because very old
5178 software may be incompatible). We could enable it by default in
5181 17 November 2010: Wouter
5182 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
5183 - make test output nicer.
5185 15 November 2010: Wouter

5187 - iana portlist updated.
5188 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
5190 9 November 2010: Wouter

5207 2 November 2010: Wouter
5211 1 November 2010: Wouter
5212 - GOST code enabled by default (RFC 5933).
5214 27 October 2010: Wouter
5215 - Fix uninit value in dump_infra print.
5216 - Fix validation failure for parent and child on same server with an
5217 insecure childzone and a CNAME from parent to child.
5218 - Configure detects libev-4.00.
5220 26 October 2010: Wouter
5221 - dump_infra and flush_infra commands for unbound-control.
5222 - no timeout backoff if meanwhile a query succeeded.
5223 - Change of timeout code. No more lost and backoff in blockage.
5224 At 12sec timeout (and at least 2x lost before) one probe per IP
5225 is allowed only. At 120sec, the IP is blocked. After 15min, a
5226 120sec entry has a single retry packet.
5228 25 October 2010: Wouter
5229 - Configure errors if ldns is not found.
5231 22 October 2010: Wouter
5232 - Windows 7 fix for the installer.

5236 observation to be noted in cache. Fix bug where EDNSprobe halted
5237 exponential backoff if EDNS status unknown.
5238 - new unresponsive host method, exponentially increasing block backoff.
5239 - iana portlist updated.
5241 20 October 2010: Wouter
5242 - interface automatic works for some people with ip6 disabled.
5243 Therefore the error check is removed, so they can use the option.
5245 19 October 2010: Wouter
5246 - Fix for request list growth, if a server has long timeout but the
5247 lost counter is low, then its effective rtt is the one without
5248 exponential backoff applied. Because the backoff is not working.
5249 The lost counter can then increase and the server is blacklisted,
5250 or the lost counter does not increase and the server is working
5253 18 October 2010: Wouter
5254 - iana portlist updated.
5256 13 October 2010: Wouter

5263 verify as secure (it was insecure by mistake).
5264 - iana portlist updated.
5265 - ldns tarball updated (for reading cachedumps with bad RR data).
5267 1 October 2010: Wouter

5276 - iana portlist updated.
5278 24 September 2010: Wouter

5281 23 September 2010: Wouter
5282 - unbound-anchor app, unbound requires libexpat (xml parser library).
5284 22 September 2010: Wouter
5285 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
5286 reverse ipv6 orchid prefix from builtin list.
5287 - iana portlist updated.
5289 17 September 2010: Wouter
5290 - DLV has downgrade protection again, because the RFC says so.
5291 - iana portlist updated.
5293 16 September 2010: Wouter
5294 - Algorithm rollover operational reality intrudes, for trust-anchor,
5295 5011-store, and DLV-anchor if one key matches it's good enough.
5296 - iana portlist updated.
5297 - Fix reported validation error in out of memory condition.
5299 15 September 2010: Wouter

5302 14 September 2010: Wouter
5303 - increased mesh-max-activation from 1000 to 3000 for crazy domains
5304 like _tcp.slb.com with 262 servers.
5305 - iana portlist updated.
5307 13 September 2010: Wouter
5308 - bug#327: Fix for cannot access stub zones until the root is primed.
5310 9 September 2010: Wouter
5311 - unresponsive servers are not completely blacklisted (because of
5312 firewalls), but also not probed all the time (because of the request
5313 list size it generates). The probe rate is 1%.
5314 - iana portlist updated.
5316 20 August 2010: Wouter
5317 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
5318 iterator get_mem includes priv_get_mem. delegpt nodup removed.
5319 listen_pushback, query_info_allocqname, write_socket, send_packet,
5320 comm_point_set_cb_arg and listen_resume removed.
5322 19 August 2010: Wouter
5323 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
5324 Delegpt structures checked for duplicates always.

5327 - iana portlist updated.
5329 18 August 2010: Wouter
5330 - Fix bug#322: configure does not respect CFLAGS on Solaris.
5331 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
5332 if use sun-cc, but some systems need different flags.
5334 16 August 2010: Wouter
5335 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
5336 changes, uses m4_bpatsubst now.
5337 - make test (or make check) should be more portable and run the unit
5338 test and testbound scripts. (make longtest has special requirements).
5340 13 August 2010: Wouter
5341 - More pleasant remote control command parsing.
5342 - documentation added for return values reported by doxygen 1.7.1.
5343 - iana portlist updated.
5345 9 August 2010: Wouter

5367 14 July 2010: Wouter
5368 - Donation text added to README.
5369 - Fix integer underflow in prefetch ttl creation from cache. This
5370 fixes a potential negative prefetch ttl.
5372 12 July 2010: Wouter
5373 - Changed the defaults for num-queries-per-thread/outgoing-range.
5374 For builtin-select: 512/960, for libevent 1024/4096 and for
5375 windows 24/48 (because of win api). This makes the ratio this way
5376 to improve resilience under heavy load. For high performance, use
5377 libevent and possibly higher numbers.
5379 10 July 2010: Wouter
5380 - GOST enabled if SSL is recent and ldns has GOST enabled too.
5381 - ldns tarball updated.
5384 - iana portlist updated.
5385 - Fix validation of qtype DNSKEY when a key-cache entry exists but
5386 no rr-cache entry is used (it expired or prefetch), it then goes
5387 back up to the DS or trust-anchor to validate the DNSKEY.
5390 - Neat function prototypes, unshadowed local declarations.
5393 - failure to chown the pidfile is not fatal any more.
5394 - testbound uses UTC timezone.
5395 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
5396 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
5399 - log if a server is skipped because it is on the donotquery list,
5400 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
5401 - added feature to print configure date, target and options with -h.
5402 - added feature to print event backend system details with -h.
5403 - wdiff is not actually required by make test, updated requirements.
5406 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
5407 must be signed with all algorithms from the DS rrset at the parent.
5408 This is now checked and becomes bogus if not.
5410 28 June 2010: Wouter
5411 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
5412 in overload situations to be about 5 qps for the class of shortly
5414 The capacity of the resolver is then about (numqueriesperthread / 2)
5415 / (average time for such long queries) qps for long queries.
5416 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
5417 qps for short queries, per thread.
5418 - Fix the max number of reply-address count to be applied for duplicate
5419 queries, and not for new query list entries. This raises the memory
5420 usage to a max of (16+1)*numqueriesperthread reply addresses.
5422 25 June 2010: Wouter
5423 - Fix handling of corner case reply from lame server, follows rfc2308.
5424 It could lead to a nodata reply getting into the cache if the search
5425 for a non-lame server turned up other misconfigured servers.
5426 - unbound.h has extern "C" statement for easier include in c++.
5428 23 June 2010: Wouter
5429 - iana portlist updated.
5430 - makedist upgraded cross compile openssl option, like this:
5431 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
5433 22 June 2010: Wouter
5434 - Unbound reports libev or libevent correctly in logs in verbose mode.
5435 - Fix to unload gost dynamic library module for leak testing.
5437 18 June 2010: Wouter
5438 - iana portlist updated.
5440 17 June 2010: Wouter
5441 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
5443 16 June 2010: Wouter
5444 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
5445 assertion was wrong.
5446 - updated ldns tarball.
5448 15 June 2010: Wouter
5449 - tag 1.4.5 created.
5450 - trunk contains 1.4.6 in development.
5451 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
5452 - Fix to use one pointer less for iterator query state store_parent_NS.
5453 - makedist crosscompile to windows uses builtin ldns not host ldns.
5454 - Max referral count from 30 to 130, because 128 one character domains
5456 - added documentation for the histogram printout to syslog.
5458 11 June 2010: Wouter
5459 - When retry to parent the retrycount is not wiped, so failed
5460 nameservers are not tried again.
5461 - iana portlist updated.
5463 10 June 2010: Wouter
5464 - Fix bug where a long loop could be entered, now cycle detection
5465 has a loop-counter and maximum search amount.
5468 - iana portlist updated.
5469 - 1.4.5rc1 tag created.
5472 - ldns tarball updated, 1.6.5.
5473 - review comments, split dependency cycle tracking for parentside
5474 last resort lookups for A and AAAA so there are more lookup options.
5477 - Fix compile warning if compiled without threads.
5478 - updated ldns-tarball with current ldns svn (pre 1.6.5).
5479 - GOST disabled-by-default, the algorithm number is allocated but the
5480 RFC is still has to pass AUTH48 at the IETF.
5483 - Ignore Z flag in incoming messages too.
5484 - Fix storage of negative parent glue if that last resort fails.
5485 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
5486 - new splint flags for newer splint install.
5489 - Fix AD flag handling, it could in some cases mistakenly copy the AD
5490 flag from upstream servers.
5491 - alloc_special_obtain out of memory is not a fatal error any more,
5492 enabling unbound to continue longer in out of memory conditions.
5493 - parentside names are dispreferred but not said to be dnssec-lame.
5494 - parentside check for cached newname glue.
5495 - fix parentside and querytargets modulestate, for dump_requestlist.
5496 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
5497 - fix parentside from cache to be marked dispreferred for bad names.
5500 - iana portlist updated.
5501 - parent-child disagreement approach altered. Older fixes are
5502 removed in place of a more exhaustive search for misconfigured data
5503 available via the parent of a delegation.
5504 This is designed to be throttled by cache entries, with TTL from the
5505 parent if possible. Additionally the loop-counter is used.
5506 It also tests for NS RRset differences between parent and child.
5507 The fetch of misconfigured data should be more reliable and thorough.
5508 It should work reliably even with no or only partial data in cache.
5509 Data received from the child (as always) is deemed more
5510 authoritative than information received from the delegation parent.
5511 The search for misconfigured data is not performed normally.
5514 - Contribution from Migiel de Vos (Surfnet): nagios patch for
5515 unbound-host, in contrib/ (in the source tarball). Makes
5516 unbound-host suitable for monitoring dnssec(-chain) status.
5519 - EDNS timeout code will not fire if EDNS status already known.
5520 - EDNS failure not stored if EDNS status known to work.
5523 - Fix resolution for domains like safesvc.com.cn. If the iterator
5524 can not recurse further and it finds the delegation in a state
5525 where it would otherwise have rejected it outhand if so received
5526 from a cache lookup, then it can try to ask higherup (with loop
5528 - Fix comments in iter_utils:dp_is_useless.
5531 - Fix various compiler warnings from the clang llvm compiler.
5532 - iana portlist updated.
5535 - Fix bug#308: spelling error in variable name in parser and lexer.
5538 - Fix dnssec-missing detection that was turned off by server selection.
5539 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
5540 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
5541 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
5543 29 April 2010: Wouter
5544 - Fix for dnssec lameness detection to use the key cache.
5545 - infra cache entries that are expired are wiped clean. Previously
5546 it was possible to not expire host data (if accessed often).
5548 28 April 2010: Wouter
5549 - ldns tarball updated and GOST support is detected and then enabled.
5550 - iana portlist updated.
5551 - Fix detection of gost support in ldns (reported by Chris Smith).
5553 27 April 2010: Wouter
5554 - unbound-control get_option domain-insecure shows config file items.
5555 - fix retry sequence if prime hints are recursion-lame.
5556 - autotrust anchor file can be initialized with a ZSK key as well.
5557 - harden-referral-path does not result in failures due to max-depth.
5558 You can increase the max-depth by adding numbers (' 0') after the
5559 target-fetch-policy, this increases the depth to which is checked.
5561 26 April 2010: Wouter
5562 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
5563 CPPFLAGS during configure process.
5564 - if libev is installed on the base system (not libevent), detect
5565 it from the event.h header file and link with -lev.
5566 - configlexer.lex gets config.h, and configyyrename.h added by make,
5567 no more double include.
5568 - More strict scrubber (Thanks to George Barwood for the idea):
5569 NS set must be pertinent to the query (qname subdomain nsname).
5570 - Fix bug#307: In 0x20 backoff fix fallback so the number of
5571 outstanding queries does not become -1 and block the request.
5572 Fixed handling of recursion-lame in combination with 0x20 fallback.
5573 Fix so RRsets are compared canonicalized and sorted if the immediate
5574 comparison fails, this makes it work around round-robin sites.
5576 23 April 2010: Wouter
5577 - Squelch log message: sendto failed permission denied for
5578 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
5579 - Fix to fetch data as last resort more tenaciously. When cycle
5580 targets cause the server selection to believe there are more options
5581 when they really are not there, the server selection is reinitiated.
5582 - Fix fetch from blacklisted dnssec lame servers as last resort. The
5583 server's IP address is then given in validator errors as well.
5584 - Fix local-zone type redirect that did not use the query name for
5587 22 April 2010: Wouter
5589 - trunk contains 1.4.5 in development.
5590 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
5591 The validator error message was 'no signatures from ...'.
5593 16 April 2010: Wouter
5594 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
5597 15 April 2010: Wouter
5598 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
5599 example key and signatures for GOST. GOST requires openssl-1.0.0.
5600 GOST is still disabled by default.
5602 9 April 2010: Wouter
5603 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
5604 get into an endless loop, if 0x20 was enabled, and buffers are small
5605 or particular broken packets are received.
5606 - Fix chain of trust with CNAME at an intermediate step, for the DS
5609 8 April 2010: Wouter
5610 - Fix validation of queries with wildcard names (*.example).
5612 6 April 2010: Wouter
5613 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
5614 cache timeout coincided with a server update, the current EDNS
5615 backoff is less sensitive, and does not cache the backoff unless
5616 the backoff actually works and the domain is not expecting DNSSEC.
5617 - GOST support with correct algorithm numbers.
5619 1 April 2010: Wouter
5620 - iana portlist updated.

5645 also assertions on ancillary data buffer.
5646 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
5647 - for NSEC3 check if signatures are cached.
5649 15 March 2010: Wouter
5650 - unit test for util/regional.c.
5652 12 March 2010: Wouter
5653 - Reordered configure checks so fork and -lnsl -lsocket checks are
5654 earlier, and thus later checks benefit from and do not hinder them.
5655 - iana portlist updated.
5656 - ldns tarball updated.
5657 - Fix python use when multithreaded.
5658 - Fix solaris python compile.

5709 - Also delete potential poison references from additional.
5710 - Fix: no classification of a forwarder as lame, throw away instead.
5712 23 February 2010: Wouter
5713 - libunbound ub_ctx_get_option() added.
5714 - unbound-control set_option and get_option commands.
5715 - iana portlist updated.
5717 18 February 2010: Wouter
5718 - A little more strict DS scrubbing.
5719 - No more blacklisting of unresponsive servers, a 2 minute timeout
5721 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.

5732 16 February 2010: Wouter
5733 - Check for 'no space left on device' (or other errors) when
5734 writing updated autotrust anchors and print errno to log.
5736 15 February 2010: Wouter
5737 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
5738 hardcoded. We made the choice to send out more conservatively,
5739 protecting against an aggregate effect more than protecting a
5740 single user (from their own folly, perhaps in case of misconfig).
5742 12 February 2010: Wouter
5743 - Re-query pattern changed on validation failure. To protect troubled
5744 authority servers, unbound caches a failure for the DNSKEY or DS
5745 records for the entire zone, and only retries that 900 seconds later.
5746 This implies that only a handful of packets are sent extra to the
5747 authority if the zone fails.
5749 11 February 2010: Wouter
5750 - ldns tarball update for long label length syntax error fix.
5751 - iana portlist updated.
5753 9 February 2010: Wouter

5777 14 January 2010: Wouter
5778 - Fixup ldns detection to also check for header files.
5780 13 January 2010: Wouter
5781 - prefetch-key option that performs DNSKEY queries earlier in the
5782 validation process, and that could halve the latency on DNSSEC
5783 queries. It takes some extra processing (CPU, a cache is needed).
5785 12 January 2010: Wouter
5786 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
5788 8 January 2010: Wouter
5789 - Fix for parent-child disagreement code which could have trouble
5790 when (a) ipv6 was disabled and (b) the TTL for parent and child
5791 were different. There were two bugs, the parent-side information
5792 is fixed to no longer block lookup of child side information and
5793 the iterator is fixed to no longer attempt to get ipv6 when it is
5794 not enabled and then give up in failure.
5795 - test and fixes to make prefetch actually store the answer in the
5796 cache. Considers some rrsets 'already expired' but does not allow
5797 overwriting of rrsets considered more secure.
5799 7 January 2010: Wouter
5800 - Fixup python documentation (thanks Leo Vandewoestijne).
5801 - Work on cache prefetch feature.
5802 - Stats for prefetch, in log print stats, unbound-control stats
5803 and in unbound_munin plugin.
5805 6 January 2010: Wouter
5806 - iana portlist updated.
5807 - bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.

5832 - requirements.txt updated with design choice explanations.
5833 - Reading fixes: fix to set unlame when child confirms parent glue,
5834 and fix to avoid duplicate addresses in delegation point.
5835 - verify_rrsig routine checks expiration last.
5837 9 December 2009: Wouter
5838 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
5839 errors generated for domain names like '.example.com'.
5840 - Fix SOA excluded from negative DS responses. Reported by Hauke
5841 Lampe. The negative cache did not include proper SOA records for
5842 negative qtype DS responses which makes BIND barf on it, such
5843 responses are now only used internally.
5844 - Fix negative cache lookup of closestencloser check of DS type bit.
5846 8 December 2009: Wouter
5847 - Fix for lookup of parent-child disagreement domains, where the
5848 parent-side glue works but it does not provide proper NS, A or AAAA
5849 for itself, fixing domains such as motorcaravanners.eu.
5850 - Feature: you can specify a port number in the interface: line, so
5851 you can bind the same interface multiple times at different ports.
5853 7 December 2009: Wouter
5854 - Bug#287: Fix segfault when unbound-control remove nonexistent local
5855 data. Added check to tests.
5857 1 December 2009: Wouter

5869 It was 1:5:0 but should have been 2:0:0.
5871 23 November 2009: Wouter
5872 - Patch from David Hubbard for libunbound manual page.
5873 - Fixup endless spinning in unbound-control stats reported by
5874 Attila Nagy. Probably caused by clock reversal.
5876 20 November 2009: Wouter

5895 - unbound-host does not fail on type ANY.
5896 - Fixed wireparse failure to put RRSIGs together with data in some
5897 long ANY mix cases, which fixes validation failures.
5899 12 November 2009: Wouter
5900 - iana portlist updated.
5901 - fix manpage errors reported by debian lintian.
5903 - fixup very long vallog2 level error strings.

5911 to combine well when combined with DLV and a particular failure.
5912 - Fixed unbound-control -h output about argument optionality.
5915 5 November 2009: Wouter

5933 - ldns tarball updated (which also enables rsasha256 support).
5935 27 October 2009: Wouter
5936 - iana portlist updated.
5938 8 October 2009: Wouter
5940 - add val-log-level print to corner case (nameserver.epost.bg).
5941 - more detail to errors from insecure delegation checks.
5942 - Fix double time subtraction in negative cache reported by
5943 Amanda Constant and Hugh Mahon.
5944 - Made new validator error string available from libunbound for
5945 applications. It is in result->why_bogus, a zero-terminated string.
5946 unbound-host prints it by default if a result is bogus.
5947 Also the errinf is public in module_qstate (for other modules).
5949 7 October 2009: Wouter
5950 - retry for validation failure in DS and prime results. Less mem use.
5951 unit test. Provisioning in other tests for requeries.

5958 - moved version number to 1.4.0 because of 1.3.4 release with only
5959 the NSEC3 patch from the entry above.
5960 - val-log-level: 2 shows extended error information for validation
5961 failures, but still one (longish) line per failure. For example:
5962 validation failure <example.com. DNSKEY IN>: signature expired from
5963 192.0.2.4 for trust anchor example.com. while building chain of trust
5964 validation failure <www.example.com. A IN>: no signatures from
5965 192.0.2.6 for key example.com. while building chain of trust
5967 6 October 2009: Wouter
5968 - Test set updated to provide additional ns lookup result.
5969 The retry would attempt to fetch the data from other nameservers
5970 for bogus data, and this needed to be provisioned in the tests.
5972 5 October 2009: Wouter
5973 - first validation failure retry code. Retries for data failures.
5976 2 October 2009: Wouter
5977 - improve 5011 modularization.
5978 - fix unbound-host so -d can be given before -C.
5979 - iana portlist updated.

5985 - review fixes to comments, removed unused code.
5987 25 September 2009: Wouter
5988 - so-rcvbuf: 4m option added. Set this on large busy servers to not
5989 drop the occasional packet in spikes due to full socket buffers.
5990 netstat -su keeps a counter of UDP dropped due to full buffers.
5991 - review of validator/autotrust.c, small fixes and comments.
5993 23 September 2009: Wouter
5994 - 5011 query failed counts verification failures, not lookup failures.
5995 - 5011 probe failure handling fixup.
5996 - test unbound reading of original autotrust data.
5997 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
5998 picked up, otherwise performs initial probe like usual.
6000 22 September 2009: Wouter
6001 - autotrust test with algorithm rollover, new ordering of checks
6002 assists in orderly rollover.
6003 - autotrust test with algorithm rollover to unknown algorithm.
6004 checks if new keys are supported before adding them.
6005 - autotrust test with trust point revocation, becomes unsigned.
6006 - fix DNSSEC-missing-signature detection for minimal responses
6007 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
6009 18 September 2009: Wouter
6010 - autotrust tests, fix trustpoint timer deletion code.
6011 fix count of valid anchors during missing remove.
6012 - autotrust: pick up REVOKE even if not signed with known other keys.

6023 15 September 2009: Wouter
6024 - iana portlist updated.
6026 10 September 2009: Wouter
6027 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
6028 - use linebuffering for log-file: output, this can be significantly
6029 faster than the previous fflush method and enable some class of
6030 resolvers to use high verbosity (for short periods).
6031 Not on windows, because line buffering does not work there.
6033 9 September 2009: Wouter
6034 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
6035 The RRsets would still expire at the normal time, but this would
6036 keep messages bogus in the cache for too long.
6037 - regression test for that bug.
6038 - documented that load_cache is meant for debugging.
6040 8 September 2009: Wouter
6041 - fixup printing errors when load_cache, they were printed to the
6042 SSL connection which broke, now to the log.

6046 - autotrust testbound scenarios.
6047 - autotrust fix that failure count is written to file.
6048 - autotrust fix that keys may become valid after add holddown time
6049 alone, before the probe returns.
6051 4 September 2009: Wouter
6052 - Changes to make unbound work with libevent-2.0.3 alpha. (in
6053 configure detection due to new ssl dependency in libevent)
6054 - do not call sphinx for documentation when python is disabled.
6055 - remove EV_PERSIST from libevent timeout code to make the code
6056 compatible with the libevent-2.0. Works with older libevent too.

6123 - autotrust work, split up DS verification of DNSKEYs.
6125 14 August 2009: Wouter
6126 - unbound-control lookup prints out infra cache information, like RTT.
6127 - Fix bug in DLV lookup reported by Amanda from Secure64.
6128 It could sometimes wrongly classify a domain as unsigned, which
6129 does not give the AD bit on replies.

6200 - iana portlist updated.
6201 - configure changes and ldns update for mingw32 crosscompile.
6203 13 July 2009: Wouter
6204 - Fix for crash at start on windows.
6205 - tag for release 1.3.2.
6206 - trunk has version 1.3.3.

6228 29 June 2009: Wouter
6229 - ldns trunk r2959 imported as tarball, because of solaris cc compile
6230 support for c99. r2960 for better configure.

6233 avoid dropped packets at routers.
6235 26 June 2009: Wouter
6236 - Fix EDNS fallback when EDNS works for short answers but long answers
6239 22 June 2009: Wouter

6251 18 June 2009: Wouter
6252 - Fix of message parse bug where (specifically) an NSEC and RRSIG
6253 in the wrong order would be parsed, but put wrongly into internal
6254 structures so that later validation would fail.
6255 - Extreme lenience for wrongly truncated replies where a positive
6256 reply has an NS in the authority but no signatures. They are
6257 turned into minimal responses with only the (secure) answer.
6258 - autoconf 2.63 for configure.
6259 - python warnings suppress. Keep python API away from header files.
6261 17 June 2009: Wouter
6262 - CREDITS entry for cz.nic, sponsoring a 'summer of code' that was

6265 16 June 2009: Wouter
6266 - Fixup opportunistic target query generation to it does not
6267 generate queries that are known to fail.
6268 - Touchup on munin total memory report.
6269 - messages picked out of the cache by the iterator are checked
6270 if their cname chain is still correct and if validation status
6271 has to be reexamined.
6273 15 June 2009: Wouter
6274 - iana portlist updated.
6276 14 June 2009: Wouter
6277 - Fixed bug where cached responses would lose their security

6279 lookups. Reported by Hauke Lampe.
6281 13 June 2009: Wouter
6282 - bug #254. removed random whitespace from example.conf.
6284 12 June 2009: Wouter
6285 - Fixup potential wrong NSEC picked out of the cache.
6286 - If unfulfilled callbacks are deleted they are called with an error.
6287 - fptr wlist checks for mesh callbacks.
6288 - fwd above stub in configuration works.
6290 11 June 2009: Wouter
6291 - Fix queries for type DS when forward or stub zones are there.
6292 They are performed to higherup domains, and thus treated as if
6293 going to higher zones when looking up the right forward or stub
6294 server. This makes a stub pointing to a local server that has
6295 a local view of example.com signed with the same keys as are
6296 publicly used work. Reported by Johan Ihren.
6297 - Added build-unbound-localzone-from-hosts.pl to contrib, from
6298 Dennis DeDonatis. It converts /etc/hosts into config statements.
6299 - same thing fixed for forward-zone and DS, chain of trust from
6300 public internet into the forward-zone works now. Added unit test.
6303 - openssl key files are opened apache-style, when user is root and
6304 before chrooting. This makes permissions on remote-control key
6305 files easier to set up. Fixes bug #251.
6306 - flush_type and flush_name remove msg cache entries.
6307 - codereview - dp copy bogus setting fix.
6310 - Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
6311 inadvertant behaviour.

6313 - 1.3.1 development in svn trunk.
6314 - iana portlist updated.

6318 - unbound_munin_ in contrib uses ps to show rss if sbrk does not work.
6321 - fixup bad free() when wrongly encoded DSA signature is seen.
6322 Reported by Paul Wouters.
6323 - review comments from Matthijs.
6326 - --enable-sha2 option. The draft rsasha256 changed its algorithm
6327 numbers too often. Therefore it is more prudent to disable the
6328 RSASHA256 and RSASHA512 support by default.
6329 - ldns trunk included as new tarball.
6330 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.
6333 - fixup doc bug in README reported by Matthew Dempsky.
6336 - update iana port list
6337 - update ldns lib tarball
6340 - detect lack of IPv6 support on XP (with a different error code).
6341 - Fixup a crash-on-exit which was triggered by a very long queue.
6342 Unbound would try to re-use ports that came free, but this is
6343 of course not really possible because everything is deleted.
6344 Most easily triggered on XP (not Vista), maybe because of the
6345 network stack encouraging large messages backlogs.
6346 - change in debug statements.
6347 - Fixed bug that could cause a crash if root prime failed when there
6348 were message backlogs.
6351 - Thanks again to Brett Carr, found an assertion that was not true.
6352 Assertion checked if recursion parent query still existed.
6354 29 April 2009: Wouter
6355 - Thanks to Brett Carr, caught windows resource leak, use
6356 closesocket() and not close() on sockets or else the network stack
6357 starts to leak handles.
6358 - Removed usage of windows Mutex because windows cannot handle enough
6359 mutexes open. Provide own mutex implementation using primitives.

6422 - clock skew checks in unbound, config statements.
6423 - nxdomain ttl considerations in requirements.txt
6425 3 April 2009: Wouter
6426 - Fixed a bug that caused messages to be stored in the cache too
6427 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
6428 targets have been more vulnerable to the TTL miscalculation bug.
6429 - documentation test fixed for python addition.
6431 2 April 2009: Wouter
6432 - pyunbound (libunbound python plugin) compiles using libtool.

6434 - iana portlist updated.
6435 - fixed bug in unbound-control flush_zone where it would not flush

6438 - python module test package.
6440 1 April 2009: Wouter
6441 - suppress errors when trying to contact authority servers that gave
6442 ipv6 AAAA records for their nameservers with ipv4 mapped contents.

6498 18 March 2009: Wouter
6499 - Added tests, unknown algorithms become insecure. fallback works.
6500 - Fix for and test for unknown algorithms in a trust anchor
6501 definition. Trust anchors with no supported algos are ignored.
6502 This means a (higher)DS or DLV entry for them could succeed, and
6503 otherwise they are treated as insecure.
6504 - domain-insecure: "example.com" statement added. Sets domain
6505 insecure regardless of chain of trust DSs or DLVs. The inverse
6508 17 March 2009: Wouter

6525 12 March 2009: Wouter
6526 - log to App.logs on windows prints executable identity.
6528 - munin plugin fix benign locking error printout.
6529 - anchor-update for windows, called every 24 hours; unbound reloads.
6531 11 March 2009: Wouter

6535 default install location.
6536 - on windows logging to the Application logbook works (as a service).
6537 - fix RUN_DIR on windows compile setting in makedist.
6538 - windows registry has Software\Unbound\ConfigFile element.

6588 have unsupported algorithms.
6589 - added contrib/update-itar.sh This script is similar to
6590 update-anchor.sh, and updates from the IANA ITAR repository.
6591 You can provide your own PGP key and trust repo, or can use the
6592 builtin. The program uses wget and gpg to work.
6593 - iana portlist updated.
6594 - update-itar.sh: using ftp:// urls because https godaddy certificate
6595 is not available everywhere and then gives fatal errors. The
6596 security is provided by pgp signature.
6598 18 February 2009: Wouter
6599 - more cycle detection. Also for target queries.
6600 - fixup bug where during deletion of the mesh queries the callbacks
6601 that were reentrant caused assertion failures. Keep the mesh in
6602 a reentrant safe state. Affects libunbound, reload of server,
6603 on quit and flush_requestlist.
6604 - iana portlist updated.
6606 13 February 2009: Wouter
6607 - forwarder information now per-thread duplicated.
6608 This keeps it read only for speed, with no locking necessary.
6609 - forward command for unbound control to change forwarders to use
6611 - document that unbound-host reads no config file by default.
6612 - updated iana portlist.
6614 12 February 2009: Wouter
6615 - call setusercontext if available (on BSD).
6616 - small refactor of stats clearing.

6636 occurred. Does not enforce a space after keyword anymore.
6637 Does not allow literal newlines inside quoted strings anymore.
6638 - verbosity level 5 logs customer IP for new requestlist entries.
6639 - test fix, lexer and cancel test.
6640 - new option log-time-ascii: yes if you enable it prints timestamps
6641 in the log file as Feb 06 13:45:26 (like syslog does).
6642 - detect event_base_new in libevent-1.4.1 and later and use it.
6643 - #231 unbound-checkconf -o option prints that value from config file.
6644 Useful for scripting in management scripts and the like.
6646 5 February 2009: Wouter
6647 - ldns 1.5.0 rc as tarball included.
6648 - 1.3.0 development continues:
6649 change in libunbound API: ub_cancel can return an error, that
6650 the async_id did not exist, or that it was already delivered.
6651 The result could have been delivered just before the cancel
6652 routine managed to acquire the lock, so a caller may get the
6653 result at the same time they call cancel. For this case,
6654 ub_cancel tries to return an error code.
6655 Fixes race condition in ub_cancel() libunbound function.
6656 - MacOSX Leopard cleaner text output from configure.
6657 - initgroups(3) is called to drop secondary group permissions, if
6659 - configure option --with-ldns-builtin forces the use of the
6660 inluded ldns package with the unbound source. The -I include
6661 is put before the others, so it avoids bad include files from
6662 an older ldns install.
6663 - daemon(3) posix call is used when available.
6664 - testbound test for older fix added.
6666 4 February 2009: Wouter

6675 16 January 2009: Wouter
6676 - more quiet about ipv6 network failures, i.e. when ipv6 is not
6677 available (network unreachable). Debug still printed on high
6679 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
6680 debugging with unbound-host -4 -d ...
6681 - more cycle detection for NS-check, addr-check, root-prime and
6682 stub-prime queries in the iterator. Avoids possible deadlock
6685 15 January 2009: Wouter
6686 - bug #229: fixup configure checks for compilation with Solaris
6687 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc
6688 - fixup suncc warnings.
6689 - fix bug where unbound could crash using libevent 1.3 and older.
6690 - update testset for recent retry change.
6692 14 January 2009: Wouter
6693 - 1.2.1 feature: negative caching for failed queries.
6694 Queries that failed are cached for 5 seconds (NORR_TTL).
6695 If the failure is local, like out of memory, it is not cached.
6696 - the TTL comparison for the cache used different comparisons,
6697 causing many cache responses that used the iterator and validator
6698 state machines unnecessarily.
6699 - retry from 4 to 5 so that EDNS drop retry is part of the first
6700 query resolve attempt, and cached error does not stop EDNS fallback.
6701 - remove debug prints that protect against bad referrals.
6702 - honor QUIET=no on make commandline (or QUIET=yes ).
6704 13 January 2009: Wouter
6705 - fixed bug in lameness marking, removed printouts.

6709 - 1.2.1 feature: stops resolving AAAAs promiscuously when they
6710 are in the negative cache.
6712 12 January 2009: Wouter
6713 - fixed bug in infrastructure lameness cache, did not lowercase
6714 name of zone to hash when setting lame.
6715 - lameness debugging printouts.
6717 9 January 2009: Wouter
6718 - created svn tag for 1.2.0 release.

6724 - new version of ldns-trunk (today) included as tarball, fixed
6725 bug #224, building with -j race condition.
6726 - remove possible race condition in the test for race conditions.
6728 7 January 2009: Wouter
6729 - version 1.2.0 in preparation.
6730 - feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
6731 statements. (Adapted from patch by Paul Wouters).
6732 - typo fix and iana portlist updated.
6733 - porting testsuite; unused var warning, and type fixup.
6735 6 January 2009: Wouter
6736 - fixup packet-of-death when compiled with --enable-debug.
6737 A malformed packet could cause an internal assertion failure.
6738 - added test for HINFO canonicalisation behaviour.
6739 - fixup reported problem with transparent local-zone data where
6740 queries with different type could get nxdomain. Now queries
6741 with a different name get resolved normally, with different type
6742 get a correct NOERROR/NODATA answer.
6743 - HINFO no longer downcased for validation, making unbound compatible
6745 - fix reading included config files when chrooted.
6746 Give full path names for include files.
6747 Relative path names work if the start dir equals the working dir.
6748 - fix libunbound message transport when no packet buffer is available.
6750 5 January 2009: Wouter
6751 - fixup getaddrinfo failure handling for remote control port.

6753 - fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
6754 - comm_timer_set performs base_set operation after event_add.
6756 18 December 2008: Wouter
6757 - fixed bug reported by Duane Wessels: error in DLV lookup, would make
6758 some zones that had correct DLV keys as insecure.
6759 - follows -rc makedist from ldns changes (no _rc).
6760 - ldns tarball updated with 1.4.1rc for DLV unit test.
6761 - verbose prints about recursion lame detection and server selection.
6762 - fixup BSD port for infra host storage. It hashed wrongly.
6763 - fixup makedist snapshot name generation.
6764 - do not reopen syslog to avoid dev/log dependency.

6767 - follows ldns makedist.sh. -rc option. autom4te dir removed.
6768 - unbound-control status command.
6769 - extended statistics has a number of ipv6 queries counter.
6770 contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
6772 16 December 2008: Wouter
6773 - follow makedist improvements from ldns, for maintainers prereleases.
6774 - snapshot version uses _ not - to help rpm distinguish the
6777 11 December 2008: Wouter
6778 - better fix for bug #219: use LOG_NDELAY with openlog() call.
6779 Thanks to Tamas Tevesz.
6781 9 December 2008: Wouter
6782 - bug #221 fixed: unbound checkconf checks if key files exist if
6783 remote control is enabled. Also fixed NULL printf when not chrooted.
6784 - iana portlist updated.
6786 3 December 2008: Wouter
6787 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
6788 freezes up unbound if this was compiled without threading, and
6789 was using multiple processes.
6790 - iana portlist updated.
6791 - test for remote control with interprocess communication.
6792 - created command distribution mechanism so that remote control
6793 commands other than 'stats' work on all processes in a nonthreaded
6794 compiled version. dump/load cache work, on the first process.
6795 - fixup remote control local_data addition memory corruption bug.
6797 1 December 2008: Wouter
6798 - SElinux policy files in contrib/selinux for the unbound daemon,
6799 by Paul Wouters and Adam Tkac.
6801 25 November 2008: Wouter
6802 - configure complains when --without-ssl is given (bug #220).
6803 - skip unsupported feature tests on vista/mingw.
6804 - fixup testcode/streamtcp to work on vista/mingw.
6805 - root-hints test checks version of dig required.
6806 - blacklisted servers are polled at a low rate (1%) to see if they
6807 come back up. But not if there is some other working server.
6809 24 November 2008: Wouter
6810 - document that the user of the server daemon needs read privileges
6811 on the keys and certificates generated by unbound-control-setup.
6812 This is different per system or distribution, usually, running the
6813 script under the same username as the server uses suffices.
6814 i.e. sudo -u unbound unbound-control-setup
6815 - testset port to vista/mingw.
6816 - tcp_sigpipe to freebsd port.
6818 21 November 2008: Wouter
6819 - fixed tcp accept, errors were printed when they should not.
6820 - unbound-control-setup.sh removes read/write permissions other
6821 from the keys it creates (as suggested by Dmitriy Demidov).
6823 20 November 2008: Wouter
6824 - fixup fatal error due to faulty error checking after tcp accept.
6825 - add check in rlimit to avoid integer underflow.
6826 - rlimit check with new formula; better estimate for number interfaces
6827 - nicer comments in rlimit check.
6828 - tag 1.1.1 created in svn.
6829 - trunk label is 1.1.2
6831 19 November 2008: Wouter
6832 - bug #219: fixed so that syslog which delays opening until the first
6833 log line is written, gets a log line while not chroot'ed yet.
6835 18 November 2008: Wouter
6836 - iana portlist updated.
6837 - removed cast in unit test debug print that was not 64bit safe.
6838 - trunk back to 1.1.0; copied to tags 1.1.0 release.
6839 - trunk to has version number 1.1.1 again.
6840 - in 1.1.1; make clean nicer. grammar in manpage.
6842 17 November 2008: Wouter
6843 - theoretical fix for problems reported on mailing list.
6844 If a delegation point has no A but only AAAA and do-ip6 is no,
6845 resolution would fail. Fixed to ask for the A and AAAA records.
6846 It has to ask for both always, so that it can fail quietly, from
6847 TLD perspective, when a zone is only reachable on one transport.
6848 - test for above, only AAAA and doip6 is no. Fix causes A record
6849 for nameserver to be fetched.
6850 - fixup address duplication on cache fillup for delegation points.
6851 - testset updated for new query answer requirements.
6853 14 November 2008: Wouter

6861 - neater comments in worker.h.
6862 - removed doc/plan and updated doc/TODO.
6863 - silenced EHOSTDOWN (verbosity 2 or higher to see it).
6864 - review comments from Jelte, Matthijs. Neater code.
6866 12 November 2008: Wouter
6867 - add unbound-control manpage to makedist replace list.
6869 11 November 2008: Wouter
6870 - unit test for negative cache, stress tests the refcounting.
6871 - fix for refcounting error that could cause fptr_wlist fatal exit
6872 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
6873 Attila Nagy for testing).
6874 - nicer comments in cachedump about failed RR to string conversion.
6875 - fix 32bit wrap around when printing large (4G and more) mem usage
6876 for extended statistics.
6878 10 November 2008: Wouter

6890 - iana portlist updated.
6892 5 November 2008: Wouter
6893 - fixed possible memory leak in key_entry_key deletion.
6894 Would leak a couple bytes when trust anchors were replaced.
6895 - if query and reply qname overlap, the bytes are skipped not copied.
6896 - fixed file descriptor leak when messages were jostled out that
6897 had outstanding (TCP) replies.
6898 - DNAMEs used from cache have their synthesized CNAMEs initialized
6900 - fixed file descriptor leak for localzone type deny (for TCP).
6901 - fixed memleak at exit for nsec3 negative cached zones.
6902 - fixed memleak for the keyword 'nodefault' when reading config.
6903 - made verbosity of 'edns incapable peer' warning higher, so you
6904 do not get spammed by it.
6905 - caught elusive Bad file descriptor error bug, that would print the
6906 error while unnecessarily try to listen to a closed fd. Fixed.
6908 4 November 2008: Wouter
6909 - fixed -Wwrite-strings warnings that result in better code.
6911 3 November 2008: Wouter
6912 - fixup build process for Mac OSX linker, use ldns b32 compat funcs.
6913 - generated configure with autoconf-2.61.
6914 - iana portlist updated.
6915 - detect if libssl needs libdl. For static linking with libssl.
6916 - changed to use new algorithm identifiers for sha256/sha512
6917 from ldns 1.4.0 (need very latest version).
6918 - updated the included ldns tarball.
6919 - proper detection of SHA256 and SHA512 functions (not just sizes).
6921 23 October 2008: Wouter
6922 - a little more debug info for failure on signer names. prints names.
6924 22 October 2008: Wouter
6925 - CFLAGS are picked up by configure from the environment.
6926 - iana portlist updated.
6927 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
6928 - new stub-prime: yesno option. Default is off, so it does not prime.
6929 can be turned on to get same behaviour as previous unbound release.
6930 - made automated test that checks if builtin root hints are uptodate.
6931 - finished draft-wijngaards-dnsext-resolver-side-mitigation
6932 implementation. The unwanted-reply-threshold can be set.
6933 - fixup so fptr_whitelist test in alloc.c works.
6935 21 October 2008: Wouter
6936 - fix update-anchors.sh, so it does not report different RR order
6937 as an update. Sorts the keys in the file. Updated copyright.
6938 - fixup testbound on windows, the command control pipe doesn't exist.
6939 - skip 08hostlib test on windows, no fork() available.
6940 - made unbound-remote work on windows.
6942 20 October 2008: Wouter
6943 - quench a log message that is debug only.
6944 - iana portlist updated.
6945 - do not query bogus nameservers. It is like nameservers that have
6946 the NS or A or AAAA record bogus are listed as donotquery.
6947 - if server selection is faced with only bad choices, it will
6948 attempt to get more options to be fetched.
6949 - changed bogus-ttl default value from 900 to 60 seconds.
6950 In anticipation that operator caused failures are more likely than
6951 actual attacks at this time. And thus repeated validation helps
6952 the operators get the problem fixed sooner. It makes validation
6953 failures go away sooner (60 seconds after the zone is fixed).
6954 Also it is likely to try different nameserver targets every minute,
6955 so that if a zone is bad on one server but not another, it is
6956 likely to pick up the 'correct' one after a couple minutes,
6957 and if the TTL is big enough that solves validation for the zone.
6958 - fixup unbound-control compilation on windows.
6960 17 October 2008: Wouter
6961 - port Leopard/G5: fixup type conversion size_t/uint32.
6962 please ranlib, stop file without symbols warning.
6963 - harden referral path now also validates the root after priming.
6964 It looks up the root NS authoritatively as well as the root servers
6965 and attemps to validate the entries.
6967 16 October 2008: Wouter
6968 - Fixup negative TTL values appearing (reported by Attila Nagy).
6970 15 October 2008: Wouter
6971 - better documentation for 0x20; remove fallback TODO, it is done.
6972 - harden-referral-path feature includes A, AAAA queries for glue,
6973 as well as very careful NS caching (only when doing NS query).
6974 A, AAAA use the delegation from the NS-query.
6976 14 October 2008: Wouter
6977 - fwd_three.tpkg test was flaky. If the three requests hit the
6978 wrong threads by chance (or bad OS) then the test would fail.
6979 Made less flaky by increasing number of retries.
6980 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
6981 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
6982 Which includes the ldns_dname_absolute fix.
6983 - fwd_three test remains flaky now that unbound does not stop
6984 listening when full. Thus, removed timeout problem.
6985 It may be serviced by three threads, or maybe by one.
6986 Mostly only useful for lock-check testing now.
6988 13 October 2008: Wouter
6989 - fixed recursion servers deployed as authoritative detection, so
6990 that as a last resort, a +RD query is sent there to get the
6992 - iana port list update.
6993 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
6995 10 October 2008: Wouter
6996 - fixup tests - the negative cache contained the correct NSEC3s for
6997 two tests that are supposed to fail to validate.
6999 9 October 2008: Wouter
7000 - negative cache caps max iterations of NSEC3 done.
7001 - NSEC3 negative cache for qtype DS works.
7003 8 October 2008: Wouter
7004 - NSEC negative cache for DS.
7006 6 October 2008: Wouter
7007 - jostle-timeout option, so you can config for slow links.
7008 - 0x20 fallback code. Tries 3xnumber of nameserver addresses
7009 queries that must all be the same. Sent to random nameservers.
7010 - documented choices for DoS, EDNS, 0x20.
7012 2 October 2008: Wouter
7013 - fixup unlink of pidfile.
7014 - fixup SHA256 algorithm collation code.
7015 - contrib/update-anchor.sh does not overwrite anchors if not needed.
7016 exits 0 when a restart is needed, other values if not.
7017 so, update-anchor.sh -d mydir && /etc/rc.d/unbound restart
7018 can restart unbound exactly when needed.
7020 30 September 2008: Wouter
7021 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
7022 - tests for sha256 support and downgrade resistance.
7023 - RSASHA256 and RSASHA512 support (using the draft in dnsext),
7024 using the drafted protocol numbers.
7025 - when using stub on localhost (127.0.0.1@10053) unbound works.
7026 Like when running NSD to host a local zone, on the same machine.
7027 The noprime feature. manpages more explanation. Added a test for it.
7028 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
7030 29 September 2008: Wouter
7031 - EDNS lameness detection, if EDNS packets are dropped this is
7032 detected, eventually.
7033 - multiple query timeout rtt backoff does not backoff too much.
7035 26 September 2008: Wouter
7036 - tests for remote-control.
7037 - small memory leak in exception during remote control fixed.

7107 - private-address and private-domain config option read, stored.
7109 2 September 2008: Wouter
7110 - DoS protection features. Queries are jostled out to make room.
7111 - testbound can pass time, increasing the internal timer.
7112 - do not mark unsigned additionals bogus, leave unchecked, which
7115 1 September 2008: Wouter
7116 - disallow nonrecursive queries for cache snooping by default.
7117 You can allow is using access-control: <subnet> allow_snoop.

7128 again. (from bugfix#199).
7129 Some errors are not written to logfile (pidfile writing, forking),
7130 and these are only visible by using the -d commandline flag.
7132 27 August 2008: Wouter
7133 - daemon(3) is causing problems for people. Reverting the patch.
7134 bug#200, and 199 and 203 contain sideline discussion on it.

7290 - skip ipv6 tests on ipv4 only hosts (requires only ipv6 localhost not
7292 - winsock event handler keeps track of sticky TCP events, that have
7293 not been fully handled yet. when interest in the event(s) resumes,
7294 they are sent again. When WOULDBLOCK is returned events are cleared.
7295 - skip tests that need signals when testing on mingw.
7297 18 June 2008: Wouter
7298 - open testbound replay files in binary mode, because fseek/ftell
7299 do not work in ascii-mode on windows. The b does nothing on unix.
7300 unittest and testbound tests work on windows (xp too).
7301 - ioctlsocket prints nicer error message.
7302 - fixed up some TCP porting for winsock.
7303 - lack of IPv6 gives a warning, no fatal error.

7306 17 June 2008: Wouter
7307 - outgoing num fds 32 by default on windows ; it supports less
7308 fds for waiting on than unixes.
7309 - winsock_event minievent handler for windows. (you could also
7310 attempt to link with libevent/libev ports for windows).
7311 - neater crypto check and gdi32 detection.
7312 - unbound.exe works to resolve and validate www.nlnetlabs.nl on vista.

7370 - bug 185: --disable-shared not passed along to ldns included with
7371 unbound. Fixed so that configure parameters are passed to the
7372 subdir configure script.
7373 fixed that ./libtool is used always, you can still override
7374 manually with ./configure libtool=mylibtool or set $libtool in
7376 - update of the ldns tarball to current ldns svn version (fix 181).

7468 It will detect and convert when necessary.
7470 14 April 2008: Wouter
7471 - got update for parseunbound.pl statistics script from Kai Storbeck.
7472 - tpkg tests for udp wait list.
7473 - documented 0x20 status.
7474 - fixup chroot and checkconf, it is much smarter now.

7476 - and check first sig byte for the encoding type.
7478 11 April 2008: Wouter
7479 - random port selection out of the configged ports.
7480 - fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
7481 - removed base_port.
7482 - created 256-port ephemeral space for the OS, 59802 available.
7483 - fixup consistency of port_if out array during heavy use.
7485 10 April 2008: Wouter

7487 - added log file statistics perl script to contrib.
7488 - automatic iana ports update from makefile. 60058 available.
7490 9 April 2008: Wouter
7491 - configure can detect libev(from its build directory) when passed
7492 --with-libevent=/home/wouter/libev-3.2
7493 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
7494 - unused commpoints not listed in epoll list.
7495 - statistics-cumulative option so that the values are not reset.
7496 - config creates array of available ports, 61841 available,
7497 it excludes <1024 and iana assigned numbers.
7498 config statements to modify the available port numbers.
7500 8 April 2008: Wouter
7501 - unbound tries to set the ulimit fds when started as server.
7502 if that does not work, it will scale back its requirements.
7504 27 March 2008: Wouter
7505 - documented /dev/random symlink from chrootdir as FAQ entry.
7507 26 March 2008: Wouter
7508 - implemented AD bit signaling. If a query sets AD bit (but not DO)
7509 then the AD bit is set in the reply if the answer validated.
7510 Without including DNSSEC signatures. Useful if you have a trusted
7511 path from the client to the resolver. Follows dnssec-updates draft.
7513 25 March 2008: Wouter
7514 - implemented check that for NXDOMAIN and NOERROR answers a query
7515 section must be present in the reply (by the scrubber). And it must
7516 be equal to the question sent, at least lowercase folded.
7517 Previously this feature happened because the cache code refused
7518 to store such messages. However blocking by the scrubber makes
7519 sure nothing gets into the RRset cache. Also, this looks like a
7520 timeout (instead of an allocation failure) and this retries are
7521 done (which is useful in a spoofing situation).
7522 - RTT banding. Band size 400 msec, this makes band around zero (fast)
7523 include unknown servers. This makes unbound explore unknown servers.
7525 7 March 2008: Wouter
7526 - -C config feature for harvest program.
7527 - harvest handles CNAMEs too.
7529 5 March 2008: Wouter
7530 - patch from Hugo Koji Kobayashi for iterator logs spelling.
7532 4 March 2008: Wouter
7533 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
7534 of a cname trust chain is lower; not full answer_AA.
7535 - test for this fix.
7536 - default config file location is /usr/local/etc/unbound.
7537 Thus prefix is used to determine the location. This is also the
7538 chroot and pidfile default location.
7540 3 March 2008: Wouter
7541 - Create 0.10 svn tag.
7542 - 0.11 version in trunk.
7543 - indentation nicer.
7545 29 February 2008: Wouter
7546 - documentation update.
7547 - fixup port to Solaris of perf test tool.
7548 - updated ldns-tarball with decl-after-statement fixes.
7550 28 February 2008: Wouter
7551 - fixed memory leaks in libunbound (during cancellation and wait).
7552 - libunbound returns the answer packet in full.
7553 - snprintf compat update.
7554 - harvest performs lookup.
7555 - ldns-tarball update with fix for ldns_dname_label.
7556 - installs to sbin by default.
7557 - install all manual pages (unbound-host and libunbound too).
7559 27 February 2008: Wouter
7560 - option to use caps for id randomness.
7561 - config file option use-caps-for-id: yes
7562 - harvest debug tool
7564 26 February 2008: Wouter
7565 - delay utility delays TCP as well. If the server that is forwarded
7566 to has a TCP error, the delay utility closes the connection.
7567 - delay does REUSE_ADDR, and can handle a server that closes its end.
7568 - answers use casing from query.
7570 25 February 2008: Wouter
7571 - delay utility works. Gets decent thoughput too (>20000).
7573 22 February 2008: Wouter
7574 - +2% for recursions, if identical queries (except for destination
7575 and query ID) in the reply list, avoid re-encoding the answer.
7576 - removed TODO items for optimizations that do not show up in
7578 - default is now minievent - not libevent. As its faster and
7579 not needed for regular installs, only for very large port ranges.
7580 - loop check different speedup pkt-dname-reading, 1% faster for
7581 nocache-recursion check.
7582 - less hashing during msg parse, 4% for recursion.
7583 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
7584 - some speed results noted:
7585 optimization resulted in +40% for recursion (cache miss) and
7586 +70 to +80 for cache hits, and +96% for version.bind.
7587 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
7588 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
7589 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
7590 So, unbound can be about equal qps to NSD in cache hits.
7591 And about 3.4x faster than BIND in cache performance.
7592 - delay utility for testing.
7594 21 February 2008: Wouter
7595 - speedup of root-delegation message encoding by 15%.
7596 - minor speedup of compress tree_lookup, maybe 1%.
7597 - speedup of dname_lab_cmp and memlowercmp - the top functions in
7598 profiler output, maybe a couple percent when it matters.
7600 20 February 2008: Wouter
7601 - setup speec_cache for need-ldns-testns in dotests.
7602 - check number of queued replies on incoming queries to avoid overload
7604 - fptr whitelist checks are not disabled in optimize mode.
7605 - do-daemonize config file option.
7606 - minievent time share initializes time at start.
7607 - updated testdata for nsec3 new algorithm numbers (6, 7).
7608 - small performance test of packet encoding (root delegation).
7610 19 February 2008: Wouter
7611 - applied patch to unbound-host man page from Jan-Piet Mens.
7612 - fix donotquery-localhost: yes default (it erroneously was switched
7614 - time is only gotten once and the value is shared across unbound.
7615 - unittest cleans up crypto, so that it has no memory leaks.
7616 - mini_event shares the time value with unbound this results in
7617 +3% speed for cache responses and +9% for recursions.
7618 - ldns tarball update with new NSEC3 sign code numbers.
7619 - perform several reads per UDP operation. This improves performance
7620 in DoS conditions, and costs very little in normal conditions.
7621 improves cache response +50%, and recursions +10%.
7622 - modified asynclook test. because the callback from async is not
7623 in any sort of lock (and thus can use all library functions freely),
7624 this causes a tiny race condition window when the last lock is
7625 released for a callback and a new cancel() for that callback.
7626 The only way to remove this is by putting callbacks into some
7627 lock window. I'd rather have the small possibility of a callback
7628 for a cancelled function then no use of library functions in
7629 callbacks. Could be possible to only outlaw process(), wait(),
7630 cancel() from callbacks, by adding another lock, but I'd rather not.
7632 18 February 2008: Wouter
7633 - patch to unbound-host from Jan-Piet Mens.
7634 - unbound host prints errors if fails to configure context.
7635 - fixup perf to resend faster, so that long waiting requests do
7636 not hold up the queue, they become lost packets or SERVFAILs,
7637 or can be sent a little while later (i.e. processing time may
7638 take long, but throughput has to be high).
7639 - fixup iterator operating in no cache conditions (RD flag unset
7641 - streamlined code for RD flag setting.
7642 - profiled code and changed dname compares to be faster.
7643 The speedup is about +3% to +8% (depending on the test).
7644 - minievent tests for eintr and eagain.
7646 15 February 2008: Wouter
7647 - added FreeBSD rc.d script to contrib.
7648 - --prefix option for configure also changes directory: pidfile:
7649 and chroot: defaults in config file.
7650 - added cache speed test, for cache size OK and cache too small.
7652 14 February 2008: Wouter
7653 - start without a config file (will complain, but start with
7655 - perf test program works.
7657 13 February 2008: Wouter

7671 - library function to put logging to a stream.
7672 - set any option interface.
7674 8 February 2008: Wouter
7675 - test program for multiple queries over a TCP channel.
7676 - tpkg test for stream tcp queries.
7677 - unbound replies to multiple TCP queries on a TCP channel.
7678 - fixup misclassification of root referral with NS in answer
7679 when validating a nonrec query.
7681 - layout of manpages, spelling fix in header, manpages process by
7682 makedist, list asynclook and tcpstream tests as ldns-testns
7685 7 February 2008: Wouter
7686 - moved up all current level 2 to be level 3. And 3 to 4.
7687 to make room for new debug level 2 for detailed information
7689 - verbosity level 2. Describes recursion and validation.
7690 - cleaner configure script and fixes for libevent solaris.
7691 - signedness for log output memory sizes in high verbosity.
7693 6 February 2008: Wouter
7694 - clearer explanation of threading configure options.
7695 - fixup asynclook test for nothreading (it creates only one process
7696 to do the extended test).
7697 - changed name of ub_val_result_free to ub_val_resolve_free.
7698 - removes warning message during library linking, renamed
7699 libunbound/unbound.c -> libunbound.c and worker to libworker.

7705 - ignore errors making directories, these can occur in parallel builds
7706 - fixup Makefile strip command and libunbound docs typo.
7708 31 January 2008: Wouter
7709 - bg thread/process reads and writes the pipe nonblocking all the time
7710 so that even if the pipe is buffered or so, the bg thread does not
7711 block, and services both pipes and queries.
7713 30 January 2008: Wouter
7714 - check trailing / on chrootdir in checkconf.
7715 - check if root hints and anchor files are in chrootdir.
7716 - no route to host tcp error is verbosity level 2.
7717 - removed unused send_reply_iov. and its configure check.
7718 - added prints of 'remote address is 1.2.3.4 port 53' to errors
7719 from netevent; the basic socket errors.
7721 28 January 2008: Wouter
7722 - fixup uninit use of buffer by libunbound (query id, flags) for
7724 - fixup uninit warning from random.c; also seems to fix sporadic
7725 sigFPE coming out of openssl.
7726 - made openssl entropy warning more silent for library use. Needs
7728 - fixup forgotten locks for rbtree_searches on ctx->query tree.
7729 - random generator cleanup - RND_STATE_SIZE removed, and instead
7730 a super-rnd can be passed at init to chain init random states.
7731 - test also does lock checks if available.
7732 - protect config access in libworker_setup().
7733 - libevent doesn't like comm_base_exit outside of runloop.

7737 - added tpkg for asynclook and library use.
7738 - allows localhost to be queried when as a library.
7739 - fixup race condition between cancel and answer (in case of
7740 really fast answers that beat the cancel).
7741 - please doxygen, put doxygen comment in one place.
7742 - asynclook -b blocking mode and test.
7743 - refactor asynclook, nicer code.
7744 - fixup race problems from opensll in rand init from library, with
7745 a mutex around the rand init.
7746 - fix pass async_id=NULL to _async resolve().
7747 - rewrote _wait() routine, so that it is threadsafe.
7748 - cancelation is threadsafe.
7749 - asynclook extended test in tpkg.
7750 - fixed two races where forked bg process waits for (somehow shared?)
7751 locks, so does not service the query pipe on the bg side.
7752 Now those locks are only held for fg_threads and for bg_as_a_thread.
7754 24 January 2008: Wouter
7755 - tested the cancel() function.
7756 - asynclook -c (cancel) feature.

7762 - new calls to set forwarding added to header and docs.
7764 23 January 2008: Wouter
7765 - removed debug prints from if-auto, verb-algo enables some.
7766 - libunbound QUIT setup, remove memory leaks, when using threads
7767 will share memory for passing results instead of writing it over
7768 the pipe, only writes ID number over the pipe (towards the handler
7769 thread that does process() ).
7771 22 January 2008: Wouter
7772 - library code for async in libunbound/unbound.c.
7773 - fix link testbound.
7774 - fixup exit bug in mini_event.
7775 - background worker query enter and result functions.
7776 - bg query test application asynclook, it looks up multiple
7777 hostaddresses (A records) at the same time.
7779 21 January 2008: Wouter
7780 - libworker work, netevent raw commpoints, write_msg, serialize.
7782 18 January 2008: Wouter
7783 - touch up of manpage for libunbound.
7784 - support for IP_RECVDSTADDR (for *BSD ip4).
7785 - fix for BSD, do not use ip4to6 mapping, make two sockets, once
7786 ip6 and once ip4, uses socket options.
7787 - goodbye ip4to6 mapping.
7788 - update ldns-testpkts with latest version from ldns-trunk.
7789 - updated makedist for relative ldns pathnames.
7790 - library API with more information inside the result structure.
7791 - work on background resolves.

7794 - fixup configure in case -lldns is installed.
7795 - fixup a couple of doxygen warnings, about enum variables.
7796 - interface-automatic now copies the interface address from the
7797 PKT_INFO structure as well.
7798 - manual page with library API, all on one page 'man libunbound'.
7799 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
7801 16 January 2008: Wouter
7802 - incoming queries to the server with TC bit on are replied FORMERR.
7803 - interface-automatic replied the wrong source address on localhost
7804 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
7805 to use ifnum=-1 to mean 'no interface, use kernel route'.
7807 15 January 2008: Wouter
7808 - interface-automatic feature. experimental. Nice for anycast.
7809 - tpkg test for ip6 ancillary data.
7810 - removed debug prints.
7811 - porting experience, define for Solaris, test refined for BSD
7812 compatibility. The feature probably will not work on OpenBSD.
7813 - makedist fixup for ldns-src in build-dir.
7815 14 January 2008: Wouter
7816 - in no debug sets NDEBUG to remove asserts.

7820 - fix lint, unit test in optimize mode.
7821 - default access control allows ::ffff:127.0.0.1 v6mapped localhost.
7823 11 January 2008: Wouter
7824 - man page, warning removed.
7825 - added text describing the use of stub zones for private zones.
7826 - checkconf tests for bad hostnames (IP address), and for doubled
7828 - memory sizes can be given with 'k', 'Kb', or M or G appended.
7830 10 January 2008: Wouter
7831 - typo in example.conf.
7832 - made using ldns-src that is included the package more portable
7833 by linking with .lo instead of .o files in the ldns package.
7834 - nicer do-ip6: yes/no documentation.
7835 - nicer linking of libevent .o files.
7836 - man pages render correctly on solaris.
7838 9 January 2008: Wouter
7839 - fixup openssl RAND problem, when the system is not configured to
7840 give entropy, and the rng needs to be seeded.
7842 8 January 2008: Wouter
7843 - print median and quartiles with extensive logging.
7845 4 January 2008: Wouter
7846 - document misconfiguration in private network.
7848 2 January 2008: Wouter
7849 - fixup typo in requirements.
7850 - document that 'refused' is a better choice than 'drop' for
7851 the access control list, as refused will stop retries.
7853 7 December 2007: Wouter
7854 - unbound-host has a -d option to show what happens. This can help
7855 with debugging (why do I get this answer).
7856 - fixup CNAME handling, on nodata, sets and display canonname.
7857 - dot removed from CNAME display.
7858 - respect -v for NXDOMAINs.
7859 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
7860 - size_t to int for portability of the header file.
7861 - fixup bogus handling.
7862 - dependencies and lint for unbound-host.
7864 6 December 2007: Wouter
7865 - library resolution works in foreground mode, unbound-host app
7867 - unbound-host prints rdata using ldns.
7868 - unbound-host accepts trust anchors, and prints validation
7869 information when you give -v.
7871 5 December 2007: Wouter
7872 - locking in context_new() inside the function.
7873 - setup of libworker.
7875 4 December 2007: Wouter
7876 - minor Makefile fixup.
7877 - moved module-stack code out of daemon/daemon into services/modstack,
7878 preparing for code-reuse.
7879 - move context into own header file.
7880 - context query structure.
7881 - removed unused variable pwd from checkconf.
7882 - removed unused assignment from outside netw.
7883 - check timeval length of string.
7884 - fixup error in val_utils getsigner.

7886 - fixup memleak on parse error in localzone.
7887 - fixup memleak on packet parse error.
7888 - put ; after union in parser.y.
7889 - small hardening in iter_operate against iq==NULL.
7890 - hardening, if error reply with rcode=0 (noerror) send servfail.
7891 - fixup same (*var) error in find_rrset in msgparse, was harmless.
7892 - check return value of evtimer_add().
7893 - fixup lockorder in lruhash_reclaim(), building up a list of locked
7894 entries one at a time. Instead they are removed and unlocked.
7895 - fptr_wlist for markdelfunc.
7896 - removed is_locked param from lruhash delkeyfunc.
7897 - moved bin_unlock during bin_split purely to please.
7899 3 December 2007: Wouter
7900 - changed checkconf/ to smallapp/ to make room for more support tools.
7901 (such as unbound-host).
7902 - install dirs created with -m 755 because they need to be accessible.
7903 - library extensive featurelist added to TODO.
7904 - please doxygen, lint.
7905 - library test application, with basic functionality.
7906 - fix for building in a subdirectory.
7907 - link lib fix for Leopard.
7909 30 November 2007: Wouter
7910 - makefile that creates libunbound.la, basic file or libunbound.a
7911 when creating static executables (no libtool).
7914 29 November 2007: Wouter
7915 - 0.9 public API start.
7917 28 November 2007: Wouter
7918 - Changeup plan for 0.8 - no complication needed, a simple solution
7919 has been chosen for authoritative features.
7920 - you can use single quotes in the config file, so it is possible
7921 to specify TXT records in local data.
7922 - fixup small memory problem in implicit transparent zone creation.
7923 - test for implicit zone creation and multiple RR RRsets local data.
7924 - local-zone nodefault test.
7925 - show testbound testlist on commit.
7926 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
7927 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
7929 - nicer verbosity: 0 and 1 levels.
7930 - lower nonRDquery chance of eliciting wrongly typed validation
7931 requiring message from the cache.
7932 - fix for nonRDquery validation typing; nodata is detected when
7933 SOA record in auth section (all validation-requiring nodata messages
7934 have a SOA record in authority, so this is OK for the validator),
7935 and NS record is needed to be a referral.
7936 - duplicate checking when adding NSECs for a CNAME, and test.
7937 - created svn tag 0.8, after completing testbed tests.
7939 27 November 2007: Wouter
7940 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
7941 - set size of msgparse lookup table to 32, from 1024, so that its size
7942 is below the 2048 regional large size threshold, and does not cause
7943 a call to malloc when a message is parsed.
7944 - update of memstats tool to print number of allocation calls.
7945 This is what is taking time (not space) and indicates the avg size
7946 of the allocations as well. region_alloc stat is removed.
7948 22 November 2007: Wouter
7949 - noted EDNS in-the-middle dropping trouble as a TODO.
7950 At this point theoretical, no user trouble has been reported.
7951 - added all default AS112 zones.
7952 - answers from local zone content.
7953 * positive answer, the rrset in question
7954 * nodata answer (exist, but not that type).
7955 * nxdomain answer (domain does not exist).
7956 * empty-nonterminal answer.
7957 * But not: wildcard, nsec, referral, rrsig, cname/dname,
7958 or additional section processing, NS put in auth.
7959 - test for correct working of static and transparent and couple
7960 of important defaults (localhost, as112, reverses).
7961 Also checks deny and refuse settings.
7962 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
7964 21 November 2007: Wouter
7965 - local zone internal data setup.
7967 20 November 2007: Wouter
7968 - 0.8 - str2list config support for double string config options.
7969 - local-zone and local-data options, config storage and documentation.
7971 19 November 2007: Wouter
7972 - do not downcase NSEC and RRSIG for verification. Follows
7973 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
7974 - fixup leaking unbound daemons at end of tests.
7975 - README file updated.
7976 - nice libevent not found error.
7977 - README talks about gnu make.
7978 - 0.8: unit test for addr_mask and fixups for it.
7979 and unit test for addr_in_common().
7980 - 0.8: access-control config file element.
7981 and unit test rpl replay file.
7982 - 0.8: fixup address reporting from netevent.
7984 16 November 2007: Wouter
7985 - privilege separation is not needed in unbound at this time.
7986 TODO item marked as such.
7987 - created beta-0.7 branch for support.
7988 - tagged 0.7 for beta release.
7989 - moved trunk to 0.8 for 0.8(auth features) development.
7990 - 0.8: access control list setup.
7992 15 November 2007: Wouter
7993 - review fixups from Jelte.
7995 14 November 2007: Wouter
7996 - testbed script does not recreate configure, since its in svn now.
7997 - fixup checkconf test so that it does not test
7998 /etc/unbound/unbound.conf.
8001 13 November 2007: Wouter
8002 - remove debug print.
8003 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
8005 12 November 2007: Wouter
8006 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
8008 - bugreports to unbound-bugs@nlnetlabs.nl
8009 - fixup testbound so it exits cleanly.
8010 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
8012 9 November 2007: Wouter
8013 - took ldns snapshot in repo.
8014 - default config file is /etc/unbound/unbound.conf.
8015 If it doesn't exist, it is installed with the doc/example.conf file.
8016 The file is not deleted on uninstall.
8017 - default listening is not all, but localhost interfaces.
8019 8 November 2007: Wouter
8020 - Fixup chroot and drop user privileges.
8021 - new L root ip address in default hints.
8023 1 November 2007: Wouter
8024 - Fixup of crash on reload, due to anchors in env not NULLed after
8025 dealloc during deinit.
8026 - Fixup of chroot call. Happens after privileges are dropped, so
8027 that checking the passwd entry still works.
8028 - minor touch up of clear() hashtable function.
8029 - VERB_DETAIL prints out what chdir, username, chroot is being done.
8030 - when id numbers run out, caches are cleared, as in design notes.
8031 Tested with a mock setup with very few bits in id, it worked.
8032 - harden-dnssec-stripped: yes is now default. It insists on dnssec
8033 data for trust anchors. Included tests for the feature.
8035 31 October 2007: Wouter
8036 - cache-max-ttl config option.
8037 - building outside sourcedir works again.
8038 - defaults more secure:
8040 chroot: "/etc/unbound"
8041 The operator can override them to be less secure ("") if necessary.
8042 - fix horrible oversight in sorting rrset references in a message,
8043 sort per reference key pointer, not on referencepointer itself.
8044 - pidfile: "/etc/unbound/unbound.pid" is now the default.
8045 - tests changed to reflect the updated default.
8046 - created hashtable clear() function that respects locks.
8048 30 October 2007: Wouter
8049 - fixup assertion failure that relied on compressed names to be
8050 smaller than uncompressed names. A packet from comrite.com was seen
8051 to be compressed to a larger size. Added it as unit test.
8052 - quieter logging at low verbosity level for common tcp messages.
8053 - no greedy TTL update.
8055 23 October 2007: Wouter
8056 - fixup (grand-)parent problem for dnssec-lameness detection.
8057 - fixup tests to do additional section processing for lame replies,
8058 since the detection needs that.
8059 - no longer trust in query section in reply during dnssec lame detect.
8060 - dnssec lameness does not make the server never ever queried, but
8061 non-preferred. If no other servers exist or answer, the dnssec lame
8062 server is used; the fastest dnssec lame server is chosen.
8063 - added test then when trust anchor cannot be primed (nodata), the
8064 insecure mode from unbound works.
8065 - Fixup max queries per thread, any more are dropped.
8067 22 October 2007: Wouter
8068 - added donotquerylocalhost config option. Can be turned off for
8070 - ISO C compat changes.
8071 - detect RA-no-AA lameness, as LAME.
8072 - DNSSEC-lameness detection, as LAME.
8073 See notes in requirements.txt for choices made.
8074 - tests for lameness detection.
8075 - added all to make test target; need unbound for fwd tests.
8076 - testbound does not pollute /etc/unbound.
8078 19 October 2007: Wouter
8079 - added configure (and its files) to svn, so that the trunk is easier
8080 to use. ./configure, config.guess, config.sub, ltmain.sh,
8082 - added yacc/lex generated files, util/configlexer.c,
8083 util/configparser.c util/configparser.h, to svn.
8084 - without lex no attempt to use it.
8085 - unsecure response validation collated into one block.
8086 - remove warning about const cast of cfgfile name.
8087 - outgoing-interfaces can be different from service interfaces.
8088 - ldns-src configure is done during unbound configure and
8089 ldns-src make is done during unbound make, and so inherits the
8090 make arguments from the unbound make invocation.
8091 - nicer error when libevent problem causes instant exit on signal.
8092 - read root hints from a root hint file (like BIND does).
8094 18 October 2007: Wouter
8095 - addresses are logged with errors.
8096 - fixup testcode fake event to remove pending before callback
8097 since the callback may create new pending items.
8098 - tests updated because retries are now in iterator module.
8099 - ldns-testpkts code is checked for differences between unbound
8100 and ldns by makedist.sh.
8101 - ldns trunk from today added in svn repo for fallback in case
8102 no ldns is installed on the system.
8103 make download_ldns refreshes the tarball with ldns svn trunk.
8104 - ldns-src.tar.gz is used if no ldns is found on the system, and
8105 statically linked into unbound.
8106 - start of regional allocator code.
8107 - regional uses less memory and variables, simplified code.
8108 - remove of region-allocator.
8109 - alloc cache keeps a cache of recently released regional blocks,
8111 - make unit test cleanly free memory.
8113 17 October 2007: Wouter
8114 - fixup another cycle detect and ns-addr timeout resolution bug.
8115 This time by refusing delegations from the cache without addresses
8116 when resolving a mandatory-glue nameserver-address for that zone.
8117 We're going to have to ask a TLD server anyway; might as well be
8118 the TLD server for this name. And this resolves a lot of cases where
8119 the other nameserver names lead to cycles or are not available.
8120 - changed random generator from random(3) clone to arc4random wrapped
8121 for thread safety. The random generator is initialised with
8122 entropy from the system.
8123 - fix crash where failure to prime DNSKEY tried to print null pointer
8125 - removed some debug prints, only verb_algo (4) enables them.
8126 - fixup test; new random generator took new paths; such as one
8127 where no scripted answer was available.
8128 - mark insecure RRs as insecure.
8129 - fixup removal of nonsecure items from the additional.
8130 - reduced timeout values to more realistic, 376 msec (262 msec has
8131 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
8132 - server selection failover to next server after timeout (376 msec).
8134 16 October 2007: Wouter
8135 - no malloc in log_hex.
8136 - assertions around system calls.
8137 - protect against gethostname without ending zero.
8138 - ntop output is null terminated by unbound.
8139 - pidfile content null termination
8140 - various snprintf use sizeof(stringbuf) instead of fixed constant.
8141 - changed loopdetect % 8 with & 0x7 since % can become negative for
8142 weird negative input and particular interpretation of integer math.
8143 - dname_pkt_copy checks length of result, to protect result buffers.
8144 prints an error, this should not happen. Bad strings should have
8145 been rejected earlier in the program.
8146 - remove a size_t underflow from msgreply size func.
8148 15 October 2007: Wouter
8150 - fix IP6 TCP, wrong definition check. With test package.
8151 - fixup the fact that the query section was not compressed to,
8152 the code was there but was called by value instead of by reference.
8153 And test for the case, uses xxd and nc.
8154 - more portable ip6 check for sockaddr types.
8156 8 October 2007: Wouter
8157 - --disable-rpath option in configure for 64bit systems with
8158 several dynamic lib dirs.
8160 7 October 2007: Wouter
8161 - fixup tests for no AD bit in non-DO queries.
8162 - test that makes sure AD bit is not set on non-DO query.
8164 6 October 2007: Wouter
8165 - removed logfile open early. It did not have the proper permissions;
8166 it was opened as root instead of the user. And we cannot change user
8167 id yet, since chroot and bind ports need to be done.
8168 - callback checks for event callbacks done from mini_event. Because
8169 of deletions cannot do this from netevent. This means when using
8170 libevent the protection does not work on event-callbacks.
8171 - fixup too small reply (did not zero counts).
8172 - fixup reply no longer AD bit when query without DO bit.
8174 5 October 2007: Wouter
8175 - function pointer whitelist.
8177 4 October 2007: Wouter
8178 - overwrite sensitive random seed value after use.
8179 - switch to logfile very soon if not -d (console attached).
8180 - error messages do not reveal the trustanchor contents.
8181 - start work on function pointer whitelists.
8183 3 October 2007: Wouter
8184 - fix for multiple empty nonterminals, after multiple DSes in the
8186 - mesh checks if modules are looping, and stops them.
8187 - refetch with CNAMEd nameserver address regression test added.
8188 - fixup line count bug in testcode, so testbound prints correct line
8189 number with parse errors.
8190 - unit test for multiple ENT case.
8191 - fix for cname out of validated unsec zone.
8192 - fixup nasty id=0 reuse. Also added assertions to detect its
8193 return (the assertion catches in the existing test cases).
8195 1 October 2007: Wouter
8196 - skip F77, CXX, objC tests in configure step.
8197 - fixup crash in refetch glue after a CNAME.
8198 and protection against similar failures (with error print).
8200 28 September 2007: Wouter
8201 - test case for unbound-checkconf, fixed so it also checks the
8202 interface: statements.
8204 26 September 2007: Wouter
8205 - SIGHUP will reopen the log file.
8206 - Option to log to syslog.
8207 - please lint, fixup tests (that went to syslog on open, oops).
8208 - config check program.
8210 25 September 2007: Wouter
8211 - tests for NSEC3. Fixup bitmap checks for NSEC3.
8212 - positive ANY response needs to check if wildcard expansion, and
8213 check that original data did not exist.
8214 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
8215 delegation, for abuse of child zone apex nsec3.
8216 - create 0.5 release tag.
8218 24 September 2007: Wouter
8219 - do not make test programs by default.
8220 - But 'make test' will perform all of the tests.
8221 - Advertise builtin select libevent alternative when no libevent
8223 - signit can generate NSEC3 hashes, for generating tests.
8224 - multiple nsec3 parameters in message test.
8225 - too high nsec3 iterations becomes insecure test.
8227 21 September 2007: Wouter
8228 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
8229 - fixup testcode lock safety (port FreeBSD).
8230 - removes subscript has type char warnings (port Solaris 9).
8231 - fixup of field with format type to int (port MacOS/X intel).
8232 - added test for infinite loop case in nonRD answer validation.
8233 It was a more general problem, but hard to reproduce. When an
8234 unsigned rrset is being validated and the key fetched, the DS
8235 sequence is followed, but if the final name has no DS, then no
8236 proof is possible - the signature has been stripped off.
8238 20 September 2007: Wouter
8239 - fixup and test for NSEC wildcard with empty nonterminals.
8240 - makedist.sh fixup for svn info.
8241 - acl features request in plan.
8242 - improved DS empty nonterminal handling.
8243 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
8244 proof anyway, which succeeds in ANS failure case.
8245 - striplab protection in case it becomes -1.
8246 - plans for static and blacklist config.
8248 19 September 2007: Wouter
8249 - comments about non-packed usage.
8250 - plan for overload support in 0.6.
8251 - added testbound tests for a failed resolution from the logs
8252 and for failed prime when missing glue.
8253 - fixup so useless delegation points are not returned from the
8254 cache. Also the safety belt is used if priming fails to complete.
8255 - fixup NSEC rdata not to be lowercased, bind compat.
8257 18 September 2007: Wouter
8258 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
8259 - validator prints subtype classification for debug.
8261 17 September 2007: Wouter
8262 - NSEC3 hash cache unit test.
8263 - validator nsec3 nameerror test.
8265 14 September 2007: Wouter
8266 - nsec3 nodata proof, nods proof, wildcard proof.
8267 - nsec3 support for cname chain ending in noerror or nodata.
8268 - validator calls nsec3 proof routines if no NSECs prove anything.
8269 - fixup iterator bug where it stored the answer to a cname under
8270 the wrong qname into the cache. When prepending the cnames, the
8271 qname has to be reset to the original qname.
8273 13 September 2007: Wouter
8274 - nsec3 find matching and covering, ce proof, prove namerror msg.
8276 12 September 2007: Wouter
8277 - fixup of manual page warnings, like for NSD bugreport.
8278 - nsec3 work, config, max iterations, filter, and hash cache.
8280 6 September 2007: Wouter
8281 - fixup to find libevent on mac port install.
8282 - fixup size_t vs unsigned portability in validator/sigcrypt.
8283 - please compiler on different platforms, for unreachable code.
8285 - pthread_rwlock type is optional, in case of old pthread libs.
8287 5 September 2007: Wouter
8288 - cname, name error validator tests.
8289 - logging of qtype ANY works.
8290 - ANY type answers get RRSIG in answer section of replies (but not
8291 in other sections, unless DO bit is on).
8292 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
8293 - DS and noDS referral validation test.
8294 - if you configure many trust anchors, parent trust anchors can
8295 securely deny existence of child trust anchors, if validated.
8296 - not all *.name NSECs are present because a wildcard was matched,
8297 and *.name NSECs can prove nodata for empty nonterminals.
8298 Also, for wildcard name NSECs, check they are not from the parent
8299 zone (for wildcarded zone cuts), and check absence of CNAME bit,
8301 - configure option for memory allocation debugging.
8302 - port configure option for memory allocation to solaris10.
8304 4 September 2007: Wouter
8305 - fixup of Leakage warning when serviced queries processed multiple
8306 callbacks for the same query from the same server.
8307 - testbound removes config file from /tmp on failed exit.
8308 - fixup for referral cleanup of the additional section.
8309 - tests for cname, referral validation.
8310 - neater testbound tpkg output.
8311 - DNAMEs no longer match their apex when synthesized from the cache.
8312 - find correct signer name for DNAME responses.
8313 - wildcarded DNAME test and fixup code to detect.
8314 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
8315 So that wildcarded CNAMEs get their NSEC with them to the answer.
8316 - test for a CNAME to a DNAME to a CNAME to an answer, all from
8317 different domains, for key fetching and signature checking of
8320 3 September 2007: Wouter
8321 - Fixed error in iterator that would cause assertion failure in
8322 validator. CNAME to a NXDOMAIN response was collated into a response
8323 with both a CNAME and the NXDOMAIN rcode. Added a test that the
8324 rcode is changed to NOERROR (because of the CNAME).
8325 - timeout on tcp does not lead to spurious leakage detect.
8326 - account memory for name of lame zones, so that memory leakages does
8327 not show lame cache growth as a leakage growth.
8328 - config setting for lameness cache expressed in bytes, instead of
8330 - tool too summarize allocations per code line.
8332 31 August 2007: Wouter
8333 - can read bind trusted-keys { ... }; files, in a compatibility mode.
8334 - iterator should not detach target queries that it still could need.
8335 the protection against multiple outstanding queries is moved to a
8336 current_query num check.
8337 - validator nodata, positive, referral tests.
8338 - dname print can print '*' wildcard.
8340 30 August 2007: Wouter
8341 - fixup override date config option.
8342 - config options to control memory usage.
8343 - caught bad free of un-alloced data in worker_send error case.
8344 - memory accounting for key cache (trust anchors and temporary cache).
8345 - memory accounting fixup for outside network tcp pending waits.
8346 - memory accounting fixup for outside network tcp callbacks.
8347 - memory accounting for iterator fixed storage.
8348 - key cache size and slabs config options.
8349 - lib crypto cleanups at exit.
8351 29 August 2007: Wouter
8352 - test tool to sign rrsets for testing validator with.
8353 - added RSA and DSA test keys, public and private pairs, 512 bits.
8354 - default configuration is with validation enabled.
8355 Only a trust-anchor needs to be configured for DNSSEC to work.
8356 - do not convert to DER for DSA signature verification.
8357 - validator replay test file, for a DS to DNSKEY DSA key prime and
8360 28 August 2007: Wouter
8361 - removed double use for udp buffers, that could fail,
8362 instead performs a malloc to do the backup.
8363 - validator validates referral messages, by validating all the rrsets
8364 and stores the rrsets in the cache. Further referral (nonRD queries)
8365 replies are made from the rrset cache directly. Unless unchecked
8366 rrsets are encountered, there are then validated.
8367 - enforce that signing is done by a parent domain (or same domain).
8368 - adjust TTL downwards if rrset TTL bigger than signature allows.
8369 - permissive mode feature, sets AD bit for secure, but bogus does
8370 not give servfail (bogus is changed into indeterminate).
8371 - optimization of rrset verification. rr canonical sorting is reused,
8372 for the same rrset. canonical rrset image in buffer is reused for
8374 - if the rrset is too big (64k exactly + large owner name) the
8375 canonicalization routine will fail if it does not fit in buffer.
8376 - faster verification for large sigsets.
8377 - verb_detail mode reports validation failures, but not the entire
8378 algorithm for validation. Key prime failures are reported as
8381 27 August 2007: Wouter
8382 - do not garble the edns if a cache answer fails.
8383 - answer norecursive from cache if possible.
8384 - honor clean_additional setting when returning secure non-recursive
8386 - do not store referral in msg cache for nonRD queries.
8387 - store verification status in the rrset cache to speed up future
8389 - mark rrsets indeterminate and insecure if they are found to be so.
8390 and store this in the cache.
8392 24 August 2007: Wouter
8393 - message is bogus if unsecure authority rrsets are present.
8394 - val-clean-additional option, so you can turn it off.
8395 - move rrset verification out of the specific proof types into one
8396 routine. This makes the proof routines prettier.
8397 - fixup cname handling in validator, cname-to-positive and cname-to-
8399 - Do not synthesize DNSKEY and DS responses from the rrset cache if
8400 the rrset is from the additional section. Signatures may have
8401 fallen off the packet, and cause validation failure.
8402 - more verbose signature date errors (with the date attached).
8403 - increased default infrastructure cache size. It is important for
8404 performance, and 1000 entries are only 212k (or a 400 k total cache
8405 size). To 10000 entries (for 2M entries, 4M cache size).
8407 23 August 2007: Wouter
8408 - CNAME handling - move needs_validation to before val_new().
8409 val_new() setups the chase-reply to be an edited copy of the msg.
8410 new classification, and find signer can find for it.
8411 removal of unsigned crap from additional, and query restart for
8413 - refuse to follow wildcarded DNAMEs when validating.
8414 But you can query for qtype ANY, or qtype DNAME and validate that.
8416 22 August 2007: Wouter
8418 - review - use val_error().
8420 21 August 2007: Wouter
8421 - ANY response validation.
8422 - store security status in cache.
8423 - check cache security status and either send the query to be
8424 validated, return the query to client, or send servfail to client.
8425 Sets AD bit on validated replies.
8426 - do not examine security status on an error reply in mesh_done.
8427 - construct DS, DNSKEY messages from rrset cache.
8428 - manual page entry for override-date.
8430 20 August 2007: Wouter
8431 - validate and positive validation, positive wildcard NSEC validation.
8432 - nodata validation, nxdomain validation.
8434 18 August 2007: Wouter
8435 - process DNSKEY response in FINDKEY state.
8437 17 August 2007: Wouter
8438 - work on DS2KE routine.
8439 - val_nsec.c for validator NSEC proofs.
8440 - unit test for NSEC bitmap reading.
8441 - dname iswild and canonical_compare with unit tests.
8443 16 August 2007: Wouter
8445 - latest release libevent 1.3c and 1.3d have threading fixed.
8446 - key entry fixup data pointer and ttl absolute.
8447 - This makes a key-prime succeed in validator, with DS or DNSKEY as
8449 - fixup canonical compare byfield routine, fix bug and also neater.
8450 - fixed iterator response type classification for queries of type
8452 dig ANY gives sometimes NS rrset in AN and NS section, and parser
8453 removes the NS section duplicate. dig NS gives sometimes the NS
8454 in the answer section, as referral.
8455 - validator FINDKEY state.
8457 15 August 2007: Wouter
8458 - crypto calls to verify signatures.
8459 - unit test for rrsig verification.
8461 14 August 2007: Wouter
8462 - default outgoing ports changed to avoid port 2049 by default.
8463 This port is widely blocked by firewalls.
8464 - count infra lameness cache in memory size.
8465 - accounting of memory improved
8466 - outbound entries are allocated in the query region they are for.
8467 - extensive debugging for memory allocations.
8468 - --enable-lock-checks can be used to enable lock checking.
8469 - protect undefs in config.h from autoheaders ministrations.
8470 - print all received udp packets. log hex will print on multiple
8472 - fixed error in parser with backwards rrsig references.
8473 - mark cycle targets for iterator did not have CD flag so failed
8476 13 August 2007: Wouter
8477 - fixup makefile, if lexer is missing give nice error and do not
8478 mess up the dependencies.
8479 - canonical compare routine updated.
8480 - canonical hinfo compare.
8481 - printout list of the queries that the mesh is working on.
8483 10 August 2007: Wouter
8484 - malloc and free overrides that track total allocation and frees.
8485 for memory debugging.
8486 - work on canonical sort.
8488 9 August 2007: Wouter
8489 - canonicalization, signature checks
8490 - dname signature label count and unit test.
8491 - added debug heap size print to memory printout.
8492 - typo fixup in worker.c
8493 - -R needed on solaris.
8494 - validator override option for date check testing.
8496 8 August 2007: Wouter
8497 - ldns _raw routines created (in ldns trunk).
8498 - sigcrypt DS digest routines
8499 - val_utils uses sigcrypt to perform signature cryptography.
8500 - sigcrypt keyset processing
8502 7 August 2007: Wouter
8503 - security status type.
8504 - security status is copied when rdata is equal for rrsets.
8505 - rrset id is updated to invalidate all the message cache entries
8506 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
8508 - val_sigcrypt file for validator signature checks.
8510 6 August 2007: Wouter
8511 - key cache for validator.
8512 - moved isroot and dellabel to own dname routines, with unit test.
8514 3 August 2007: Wouter
8516 - scrubber check section of lame NS set.
8517 - trust anchors can be in config file or read from zone file,
8518 DS and DNSKEY entries.
8519 - unit test trust anchor storage.
8520 - trust anchors converted to packed rrsets.
8521 - key entry definition.
8523 2 August 2007: Wouter
8524 - configure change for latest libevent trunk version (needs -lrt).
8525 - query_done and walk_supers are moved out of module interface.
8526 - fixup delegation point duplicates.
8527 - fixup iterator scrubber; lame NS set is let through the scrubber
8528 so that the classification is lame.
8529 - validator module exists, and does nothing but pass through,
8530 with calling of next module and return.
8533 1 August 2007: Wouter
8534 - set version to 0.5
8535 - module work for module to module interconnections.
8536 - config of modules.
8537 - detect cycle takes flags.
8539 31 July 2007: Wouter
8543 30 July 2007: Wouter
8544 - changed random state init, so that sequential process IDs are not
8545 cancelled out by sequential thread-ids in the random number seed.
8546 - the fwd_three test, which sends three queries to unbound, and
8547 unbound is kept waiting by ldns-testns for 3 seconds, failed
8548 because the retry timeout for default by unbound is 3 seconds too,
8549 it would hit that timeout and fail the test. Changed so that unbound
8550 is kept waiting for 2 seconds instead.
8552 27 July 2007: Wouter
8553 - removed useless -C debug option. It did not work.
8554 - text edit of documentation.
8555 - added doc/CREDITS file, referred to by the manpages.
8558 26 July 2007: Wouter
8559 - cycle detection, for query state dependencies. Will attempt to
8560 circumvent the cycle, but if no other targets available fails.
8561 - unit test for AXFR, IXFR response.
8562 - test for cycle detection.
8564 25 July 2007: Wouter
8565 - testbound read ADDRESS and check it.
8566 - test for version.bind and friends.
8567 - test for iterator chaining through several referrals.
8568 - test and fixup for refetch for glue. Refetch fails if glue
8569 is still not provided.
8571 24 July 2007: Wouter
8572 - Example section in config manual.
8573 - Addr stored for range and moment in replay.
8575 20 July 2007: Wouter
8576 - Check CNAME chain before returning cache entry with CNAMEs.
8577 - Option harden-glue, default is on. It will discard out of zone
8578 data. If disabled, performance is faster, but spoofing attempts
8579 become a possibility. Note that still normalize scrubbing is done,
8580 and that the potentially spoofed data is used for infrastructure
8581 and not returned to the client.
8582 - if glue times out, refetch by asking parent of delegation again.
8583 Much like asking for DS at the parent side.
8584 - TODO items from forgery-resilience draft.
8585 and on memory handling improvements.
8586 - renamed module_event_timeout to module_event_noreply.
8587 - memory reporting code; reports on memory usage after handling
8588 a network packet (not on cache replies).
8590 19 July 2007: Wouter
8591 - shuffle NS selection when getting nameserver target addresses.
8592 - fixup of deadlock warnings, yield cpu in checklock code so that
8593 freebsd scheduler selects correct process to run.
8594 - added identity and version config options and replies.
8595 - store cname messages complete answers.
8597 18 July 2007: Wouter
8598 - do not query addresses, 127.0.0.1, and ::1 by default.
8600 17 July 2007: Wouter
8601 - forward zone options in config file.
8602 - forward per zone in iterator. takes precedence over stubs.
8603 - fixup commithooks.
8604 - removed forward-to and forward-to-port features, subsumed by
8606 - fix parser to handle absent server: clause.
8607 - change untrusted rrset test to account for scrubber that is now
8608 applied during the test (which removes the poison, by the way).
8609 - feature, addresses can be specified with @portnumber, like nsd.conf.
8610 - test config files changed over to new forwarder syntax.
8612 27 June 2007: Wouter
8613 - delete of mesh does a postorder traverse of the tree.
8614 - found and fixed a memory leak. For TTL=0 messages, that would
8615 not be cached, instead the msg-replyinfo structure was leaked.
8616 - changed server selection so it will filter out hosts that are
8617 unresponsive. This is defined as a host with the maximum rto value.
8618 This means that unbound tried the host for retries up to 120 secs.
8619 The rto value will time out after host-ttl seconds from the cache.
8620 This keeps such unresolvable queries from taking up resources.
8621 - utility for keeping histogram.
8623 26 June 2007: Wouter
8624 - mesh is called by worker, and iterator uses it.
8625 This removes the hierarchical code.
8626 QueryTargets state and Finished state are merged for iterator.
8627 - forwarder mode no longer sets AA bit on first reply.
8628 - rcode in walk_supers is not needed.
8630 25 June 2007: Wouter
8632 - error encode routine for ease.
8634 22 June 2007: Wouter
8635 - removed unused _node iterator value from rbtree_t. Takes up space.
8636 - iterator can handle querytargets state without a delegation point
8637 set, so that a priming(stub) subquery error can be handled.
8638 - iterator stores if it is priming or not.
8639 - log_query_info() neater logging.
8640 - changed iterator so that it does not alter module_qstate.qinfo
8641 but keeps a chase query info. Also query_flags are not altered,
8642 the iterator uses chase_flags.
8643 - fixup crash in case no ports for the family exist.
8645 21 June 2007: Wouter
8646 - Fixup secondary buffer in case of error callback.
8647 - cleanup slumber list of runnable states.
8648 - module_subreq_depth fails to work in slumber list.
8649 - fixup query release for cached results to sub targets.
8650 - neater error for tcp connection failure, shows addr in verbose.
8651 - rbtree_init so that it can be used with preallocated memory.
8653 20 June 2007: Wouter
8654 - new -C option to enable coredumps after forking away.
8656 - fixup CNAME generation by scrubber, and memory allocation of it.
8657 - fixup deletion of serviced queries when all callbacks delete too.
8658 - set num target queries to 0 when you move them to slumber list.
8659 - typo in check caused subquery errors to be ignored, fixed.
8660 - make lint happy about rlim_t.
8661 - freeup of modules after freeup of module-states.
8662 - duplicate replies work, this uses secondary udp buffer in outnet.
8664 19 June 2007: Wouter
8665 - nicer layout in stats.c, review 0.3 change.
8666 - spelling improvement, review 0.3 change.
8667 - uncapped timeout for server selection, so that very fast or slow
8668 servers will stand out from the rest.
8669 - target-fetch-policy: "3 2 1 0 0" config setting.
8670 - fixup queries answered without RD bit (for root prime results).
8671 - refuse AXFR and IXFR requests.
8672 - fixup RD flag in error reply from iterator. fixup RA flag from
8674 - fixup encoding of very short edns buffer sizes, now sets TC bit.
8675 - config options harden-short-bufsize and harden-large-queries.
8677 18 June 2007: Wouter
8678 - same, move subqueries to slumber list when first has resolved.
8679 - fixup last fix for duplicate callbacks.
8680 - another offbyone in targetcounter. Also in Java prototype by the way.
8682 15 June 2007: Wouter
8683 - if a query asks to be notified of the same serviced query result
8684 multiple times, this will succeed. Only one callback will happen;
8685 multiple outbound-list entries result (but the double cleanup of it
8687 - when iterator moves on due to CNAME or referral, it will remove
8688 the subqueries (for other targets). These are put on the slumber
8690 - state module wait subq is OK with no new subqs, an old one may have
8691 stopped, with an error, and it is still waiting for other ones.
8692 - if a query loops, halt entire query (easy way to clean up properly).
8694 14 June 2007: Wouter
8695 - num query targets was > 0 , not >= 0 compared, so that fetch
8696 policy of 0 did nothing.
8698 13 June 2007: Wouter
8699 - debug option: configure --enable-static-exe for compile where
8700 ldns and libevent are linked statically. Default is off.
8701 - make install and make uninstall. Works with static-exe and without.
8702 installation of unbound binary and manual pages.
8703 - alignment problem fix on solaris 64.
8704 - fixup address in case of TCP error.
8706 12 June 2007: Wouter
8707 - num target queries was set to 0 at a bad time. Default it to 0 and
8708 increase as target queries are done.
8709 - synthesize CNAME and DNAME responses from the cache.
8710 - Updated doxygen config for doxygen 1.5.
8711 - aclocal newer version.
8712 - doxygen 1.5 fixes for comments (for the strict check on docs).
8714 11 June 2007: Wouter
8715 - replies on TCP queries have the address field set in replyinfo,
8716 for serviced queries, because the initiator does not know that
8717 a TCP fallback has occured.
8718 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
8719 if qtype directly queries for the type (and then only show that
8720 'unknown type' in the answer section).
8721 - fixed message parsing where rrsigs on their own would be put
8722 in the signature list over the rrsig type.

8751 - memleak in config file stubs fixup.
8752 - more small bugs, in scrubber, query compare no ID for lookup,
8753 in dname validation for NS targets.
8754 - sets entry.key for new special allocs.
8755 - lognametypeclass can display unknown types and classes.
8758 - random selection of equally preferred nameserver targets.

8779 and lameness is checked too.
8780 - delegation point copy routine.
8783 - removed FLAG_CD from message and rrset caches. This was useful for
8784 an agnostic forwarder, but not for a sophisticated (trust value per
8785 rrset enabled) cache.

8920 - decompress query section, extremely lenient acceptance.
8921 But only for answers from other servers, not for plain queries.
8922 - compression and decompression test cases.
8924 - example.conf interface: line is changed from 127.0.0.1 which leads
8925 to problems if used (restricting communication to the localhost),

9109 to not change protected memory areas.
9110 - log_hex function to dump hex strings to the logfile.
9111 - checklocks zeroes its destroyed lock after checking memory areas.
9112 - unit test for alloc.

9148 so that they do not result in problems.
9149 - Also randomize the outgoing port range for tests.

9151 This makes all threads service incoming requests, instead of one.
9152 No memory is leaking during reloads, service of queries, etc.
9153 - test that uses ldns-testns -f to test threading. Have to answer
9154 three queries at the same time.

9167 except the listening ports. Then the config file is reread.
9168 And everything is started again (and listening ports if needed).
9169 - Ports for queries are shared.
9170 - config file added interface:, chroot: and username:.
9171 - config file: directory, logfile, pidfile. And they work too.

9203 It is limited to 1024 file descriptors, and has less features.
9204 - will not create ip6 sockets if ip6 not on the machine.
9206 15 February 2007: Wouter
9207 - port to FreeBSD 4.11 Dec Alpha. Also works on Solaris 10 sparc64,
