2 - Tag for 1.8.0rc1 release.
5 - Disable minimal-responses in subnet unit tests.
8 - Fix that a local-zone with a local-zone-type that is transparent
9 in a view with view-first, makes queries check for answers from the
10 local-zones defined outside of views.
13 - Disable minimal-responses in ipsecmod unit tests.
14 - Added serve-expired-ttl and serve-expired-ttl-reset options.
16 27 August 2018: Wouter
17 - Set defaults to yes for a number of options to increase speed and
18 resilience of the server. The so-reuseport, harden-below-nxdomain,
19 and minimal-responses options are enabled by default. They used
20 to be disabled by default, waiting to make sure they worked. They
21 are enabled by default now, and can be disabled explicitly by
22 setting them to "no" in the unbound.conf config file. The reuseport
23 and minimal options increases speed of the server, and should be
24 otherwise harmless. The harden-below-nxdomain option works well
25 together with the recently default enabled qname minimisation, this
26 causes more fetches to use information from the cache.
27 - next release is called 1.8.0.
28 - Fix lintflags for lint on FreeBSD.
30 22 August 2018: George

45 - Fix classification for QTYPE=CNAME queries when QNAME minimisation is
48 17 August 2018: Wouter
49 - Set libunbound to increase current, because the libunbound change
50 to the event callback function signature. That needs programs,
51 that use it, to recompile against the new header definition.
52 - print servfail info to log as error.
53 - added more servfail printout statements, to the iterator.
54 - log-servfail: yes prints log lines that say why queries are
55 returning SERVFAIL to clients.

88 about missing privileges during startup). Add 'AF_INET6' to
89 'RestrictAddressFamilies' (without it IPV6 can't work). From
91 - Patch to implement tcp-connection-limit from Jim Hague (Sinodun).
92 This limits the number of simultaneous TCP client connections
93 from a nominated netblock.
94 - make depend, yacc, lex, doc, headers. And log the limit exceeded
95 message only on high verbosity, so as to not spam the logs when
99 - Fix for #4136: Fix to unconditionally call destroy in daemon.c.
101 3 August 2018: George
102 - Expose if a query (or a subquery) was ratelimited (not src IP
103 ratelimiting) to libunbound under 'ub_result.was_ratelimited'.

129 and implement option in client responses.
130 - Correct and expand manual page entries for keepalive and idle timeout.
131 - Implement progressive backoff of TCP idle/keepalive timeout.
132 - Fix 'make depend' to work when build dir is not project root.
133 - Add delay parameter to streamtcp, -d secs.
134 To be used when testing idle timeout.

722 - [dnscrypt] prevent dnscrypt-secret-key, dnscrypt-provider-cert
724 - [dnscrypt] introduce dnscrypt-provider-cert-rotated option,
726 This option allows handling multiple cert/key pairs while only
727 distributing some of them.
728 In order to reliably match a client magic with a given key without
729 strong assumption as to how those were generated, we need both key and
730 cert. Likewise, in order to know which ES version should be used.
731 On the other hand, when rotating a cert, it can be desirable to only
732 serve the new cert but still be able to handle clients that are still
733 using the old certs's public key.
734 The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not
735 publish the cert as part of the DNS's provider_name's TXT answer.

2155 for secure domain name system traffic.
2156 If you used to rely on the older default of port 443, you have
2157 to put a clause in unbound.conf for that. The new value is likely
2158 going to be the standardised port number for this traffic.

2282 - iana portlist update.
2283 - documentation proposes ratelimit of 1000 (closer to what upstream
2284 servers expect from us).
2287 - DLV is going to be decommissioned. Advice to stop using it, and
2288 put text in the example configuration and man page to that effect.
2291 - Change syntax of particular validator error to be easier for
2292 machine parse, swap rrset and ip adres info so it looks like:
2293 validation failure <www.example.nl. TXT IN>: signature crypto
2294 failed from 2001:DB8:7:bba4::53 for <*.example.nl. NSEC IN>
2297 - caps-whitelist in unbound.conf allows whitelist of loadbalancers

2313 16 April 2015: Wouter
2314 - Add local-zone type inform_deny, that logs query and drops answer.

2336 7 April 2015: Wouter
2337 - Libunbound skips dos-line-endings from etc/hosts.
2338 - Unbound exits with a fatal error when the auto-trust-anchor-file
2339 fails to be writable. This is seconds after startup. You can
2340 load a readonly auto-trust-anchor-file with trust-anchor-file.
2341 The file has to be writable to notice the trust anchor change,
2342 without it, a trust anchor change will be unnoticed and the system
2343 will then become inoperable.
2344 - unbound-control list_insecure command shows the negative trust
2345 anchors currently configured, patch from Jelte Jansen.

2767 - Code cleanup patch from Dag-Erling Smorgrav, with compiler issue
2768 fixes from FreeBSD's copy of Unbound, he notes:
2769 Generate unbound-control-setup.sh at build time so it respects
2770 prefix and sysconfdir from the configure script. Also fix the
2771 umask to match the comment, and the comment to match the umask.
2772 Add const and static where needed. Use unions instead of
2773 playing pointer poker. Move declarations that are needed in
2774 multiple source files into a shared header. Move sldns_bgetc()
2775 from parse.c to buffer.c where it belongs. Introduce a new
2776 header file, worker.h, which declares the callbacks that
2777 all workers must define. Remove those declarations from
2778 libworker.h. Include the correct headers in the correct places.
2779 Fix a few dummy callbacks that don't match their prototype.

2781 Remove a useless printf which breaks reproducible builds.
2782 Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
2783 no longer used. Add unbound-control-setup.sh to the list of
2784 generated files. The prototype for libworker_event_done_cb()

2806 - iana portlist updated.
2809 - Contrib windows scripts from Yuri Voinov added to src/contrib:

2856 on the same log-line as the error.

2890 - iana portlist updated.
2892 20 February 2014: Matthijs
2893 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
2894 received. This is okay according 4035, but not after revising
2895 existence in 4592. NSEC empty non-terminals exist and thus the
2896 RCODE should have been NOERROR. If this occurs, and the RRsets
2897 are secure, we set the RCODE to NOERROR and the security status
2898 of the response is also considered secure.
2900 14 February 2014: Wouter

2936 30 January 2014: Wouter
2937 - delay-close does not act if there are udp-wait queries, so that
2938 it does not make a socketdrain DoS easier.
2940 28 January 2014: Wouter
2941 - iana portlist updated.
2942 - iana portlist test updated so it does not touch the source
2943 if there are no changes.
2944 - delay-close: msec option that delays closing ports for which
2945 the UDP reply has timed out. Keeps the port open, only accepts
2946 the correct reply. This correct reply is not used, but the port
2947 is open so that no port-denied ICMPs are generated.
2949 27 January 2014: Wouter
2950 - reuseport is attempted, then fallback to without on failure.
2952 24 January 2014: Wouter
2953 - Change unbound-event.h to use void* buffer, length idiom.
2954 - iana portlist updated.
2955 - unbound-event.h is installed if you configure --enable-event-api.
2956 - speed up unbound (reports say it could be up to 10%), by reducing
2957 lock contention on localzones.lock. It is changed to an rwlock.
2958 - so-reuseport: yesno option to distribute queries evenly over
2959 threads on Linux (Thanks Robert Edmonds).
2962 21 January 2014: Wouter
2963 - Fix #547: no trustanchor written if filesystem full, fclose checked.
2965 17 January 2014: Wouter
2966 - Fix isprint() portability in sldns, uses unsigned int.
2967 - iana portlist updated.
2969 16 January 2014: Wouter
2970 - fix #544: Fixed +i causes segfault when running with module conf
2972 - Windows port, adjust %lld to %I64d, and warning in win_event.c.
2974 14 January 2014: Wouter
2975 - iana portlist updated.
2978 - Fix bug in cachedump that uses sldns.
2979 - update pythonmod for ldns_ to sldns_ name change.
2982 - Fix sldns to use sldns_ prefix for all ldns_ variables.
2983 - Fix windows compile to compile with sldns.
2986 - Fix sldns to make globals use sldns_ prefix. This fixes
2987 linking with libldns that uses global variables ldns_ .
2990 - Fix bug#537: compile python plugin without ldns library.
2993 - Fix bug#536: acl_deny_non_local and refuse_non_local added.
2996 - Patch from Neel Goyal to fix async id assignment if callback
2997 is called by libunbound in the mesh attach.
2998 - Accept ip-address: as an alternative for interface: for
2999 consistency with nsd.conf syntax.
3002 - Patch from Neel Goyal to fix callback in libunbound.
3005 - if configured --with-libunbound-only fix make install.
3008 - Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
3009 more specific interface port 53 can be used at the same time, and
3010 one of the daemons is unbound.
3011 - iana portlist update.
3012 - separate ldns into core ldns inside ldns/ subdirectory. No more
3013 --with-ldns is needed and unbound does not rely on libldns.
3014 - portability fixes for new USE_SLDNS ldns subdir codebase.
3017 - Patch from Neel Goyal: Add an API call to set an event base on an
3018 existing ub_ctx. This basically just destroys the current worker and
3019 sets the event base to the current. And fix a deadlock in
3020 ub_resolve_event – the cfglock is held when libworker_create is
3021 called. This ends up trying to acquire the lock again in
3022 context_obtain_alloc in the call chain.
3023 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
3026 - unbound-event.h is installed if configured --with-libevent. It
3027 contains low-level library calls, that use libevent's event_base
3028 and an ldns_buffer for the wire return packet to perform async
3029 resolution in the client's eventloop.

3100 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
3101 immediately. The others are mostly useful for libunbound users.
3104 - get_option, set_option, unbound-checkconf -o and libunbound
3105 getoption and setoption support cache-min-ttl and cache-max-ttl.
3108 - Fix#501: forward-first does not recurse, when forward name is ".".
3109 - iana portlist update.
3110 - Max include depth is unlimited.
3113 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply

3576 for use on the public internet (the protocol numbers have not
3577 been assigned). Needs recent ldns with --enable-ecdsa.
3578 - fix memory leak in errorcase for DSA signatures.
3579 - iana portlist updated.
3580 - workaround for openssl 0.9.8 ecdsa sha2 and evp problem.

3590 1 February 2012: Wouter
3591 - Fix validation failures (like: validation failure xx: no NSEC3
3592 closest encloser from yy for DS zz. while building chain of trust,
3593 because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
3594 for an NSEC3. Now it does not change rdata, and fixes TTL.
3596 30 January 2012: Wouter
3597 - Fix version-number in libtool to be version-info so it produces
3598 libunbound.so.2 like it should.

3606 23 January 2012: Wouter
3607 - Fix memset in test code.
3609 20 January 2012: Wouter
3610 - Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
3612 19 January 2012: Wouter
3613 - Fix to write key files completely to a temporary file, and if that
3614 succeeds, replace the real key file. So failures leave a useful file.
3616 18 January 2012: Wouter
3617 - tag 1.4.15rc1 created
3618 - updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
3620 17 January 2012: Wouter
3621 - Fix bug where canonical_compare of RRSIG did not downcase the
3622 signer-name. This is mostly harmless because RRSIGs do not have
3623 to be sorted in canonical order, usually.
3625 12 January 2012: Wouter
3626 - bug#428: add ub_version() call to libunbound. API version increase,
3627 with (binary) backwards compatibility for the previous version.
3629 10 January 2012: Wouter
3630 - Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
3631 that would be permissible by the RFCs but it is not the TTL in the
3633 - iana portlist updated.
3634 - uninitialised variable in reprobe for rtt blocked domains fixed.
3635 - lintfix and new flex output.
3637 2 January 2012: Wouter
3638 - Fix to randomize hash function, based on 28c3 congress, reported
3641 24 December 2011: Wouter
3642 - Fix for memory leak (about 20 bytes when a tcp or udp send operation
3643 towards authority servers failed, takes about 50.000 such failures to
3644 leak one Mb, such failures are also usually logged), reported by
3646 - iana portlist updated.
3648 19 December 2011: Wouter
3649 - Fix for VU#209659 CVE-2011-4528: Unbound denial of service
3650 vulnerabilities from nonstandard redirection and denial of existence
3651 http://www.unbound.net/downloads/CVE-2011-4528.txt

3676 - Fix for tcp-upstream and ssl-upstream for if a laptop sleeps, causes
3677 SERVFAILs. Also fixed for UDP (but less likely).
3679 28 November 2011: Wouter
3680 - Fix quartile time estimate, it was too low, (thanks Jan Komissar).
3681 - iana ports updated.
3683 11 November 2011: Wouter
3684 - Makefile compat with SunOS make, BSD make and GNU make.
3685 - iana ports updated.
3687 10 November 2011: Wouter

3704 - iana portlist updated.
3705 - fix -flto detection on Lion for llvm-gcc.
3707 31 October 2011: Wouter
3708 - dns over ssl support, ssl-service-pem and ssl-service-key files
3709 can be given and then TCP queries are serviced wrapped in SSL.
3711 27 October 2011: Wouter
3712 - lame-ttl and lame-size options no longer exist, it is integrated
3713 with the host info. They are ignored (with verbose warning) if
3714 encountered to keep the config file backwards compatible.
3715 - fix iana-update for changing gzip compression of results.
3716 - fix export-all-symbols on OSX.
3718 26 October 2011: Wouter

3725 - Fix resolve of partners.extranet.microsoft.com with a fix for the
3726 server selection for choosing out of a (particular) list of bad
3728 - Fix make_new_space function so that the incoming query is not
3729 overwritten if a jostled out query causes a waiting query to be
3730 resumed that then fails and sends an error message. (Thanks to
3733 21 October 2011: Wouter
3734 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
3735 option enabled because of memory layout exe vs dll.
3737 19 October 2011: Wouter
3738 - fix unbound-anchor for broken strptime on OSX lion, detected
3740 - Detect if GOST really works, openssl1.0 on OSX fails.
3741 - Implement ipv6%interface notation for scope_id usage.
3743 17 October 2011: Wouter
3744 - better documentation for inform_super (Thanks Yang Zhe).
3746 14 October 2011: Wouter
3747 - Fix for out-of-memory condition in libunbound (thanks
3750 13 October 2011: Wouter
3751 - Fix --enable-allsymbols, it depended on link specifics of the
3752 target platform, or fptr_wlist assertion failures could occur.
3754 12 October 2011: Wouter
3755 - updated contrib/unbound_munin_ to family=auto so that it works with
3756 munin-node-configure automatically (if installed as
3757 /usr/local/share/munin/plugins/unbound_munin_ ).
3759 27 September 2011: Wouter
3760 - unbound.exe -w windows option for start and stop service.
3762 23 September 2011: Wouter
3763 - TCP-upstream calculates tcp-ping so server selection works if there
3766 20 September 2011: Wouter
3767 - Fix classification of NS set in answer section, where there is a
3768 parent-child server, and the answer has the AA flag for dir.slb.com.
3769 Thanks to Amanda Constant from Secure64.
3771 16 September 2011: Wouter
3772 - fix bug #408: accept patch from Steve Snyder that comments out
3773 unused functions in lookup3.c.
3774 - iana portlist updated.
3775 - fix EDNS1480 change memleak and TCP fallback.
3776 - fix various compiler warnings (reported by Paul Wouters).
3777 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
3778 fetch if sentcount > 3, stop query if sentcount > 16. Count is
3779 reset when referral or CNAME happens. This makes unbound better
3780 at managing large NS sets, they are explored when there is continued
3781 interest (in the form of queries).
3783 15 September 2011: Wouter
3785 - trunk contains 1.4.14 in development.
3786 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
3788 12 September 2011: Wouter
3789 - Reverted dns EDNS backoff fix, it did not help and needs
3790 fragmentation fixes instead.
3793 7 September 2011: Wouter
3794 - Fix operation in ipv6 only (do-ip4: no) mode.
3796 6 September 2011: Wouter
3797 - fedora specfile updated.
3799 5 September 2011: Wouter
3802 2 September 2011: Wouter
3803 - iana portlist updated.
3805 26 August 2011: Wouter
3806 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
3807 - Fix validation failures due to EDNS backoff retries, the retry
3808 for fetch of data has want_dnssec because the iter_indicate_dnssec
3809 function returns true when validation failure retry happens, and
3810 then the serviced query code does not fallback to noEDNS, even if
3811 the cache says it has this. This helps for DLV deployment when
3812 the DNSSEC status is not known for sure before the lookup concludes.
3814 24 August 2011: Wouter
3815 - Applied patch from Karel Slany that fixes a memory leak in the
3816 unbound python module, in string conversions.
3818 22 August 2011: Wouter
3819 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
3820 Zhang and Luo Ce). Unbound responds with the RR types that are
3821 available at the name for qtype ANY and validates those RR types.
3822 It does not test for completeness (i.e. with NSEC or NSEC3 query),
3823 and it does not follow the CNAME or DNAME to another name (with
3824 even more data for the already large response).
3825 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
3826 - Documented the options that work with control set_option command.
3827 - tcp-upstream yes/no option (works with set_option) for tunnels.
3829 18 August 2011: Wouter
3830 - fix autoconf call in makedist crosscompile to RC or snapshot.
3832 17 August 2011: Wouter

3835 - iana portlist updated.
3837 10 August 2011: Wouter
3838 - Fix python site-packages path to /usr/lib64.
3839 - updated patch from Tom.

3842 9 August 2011: Wouter
3843 - patch from Tom Hendrikx fixes load of python modules.
3845 8 August 2011: Wouter

3848 1 August 2011: Wouter
3849 - Fix autoconf 2.68 warnings
3851 14 July 2011: Wouter
3852 - Unbound implements RFC6303 (since version 1.4.7).
3853 - tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
3854 meantime, those are for 1.4.13).
3855 - iana portlist updated.
3857 13 July 2011: Wouter
3858 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
3860 11 July 2011: Wouter
3861 - Fix wildcard expansion no-data reply under an optout NSEC3 zone is
3862 validated as insecure, reported by Jia Li (lijia@cnnic.cn).
3865 - 1.4.12rc1 tag created.
3868 - version number in example config file.
3869 - fix that --enable-static-exe does not complain about it unknown.
3871 30 June 2011: Wouter
3872 - tag relase 1.4.11, trunk is 1.4.12 development.
3873 - iana portlist updated.
3874 - fix bug#395: id bits of other query may leak out under conditions
3875 - fix replyaddr count wrong after jostled queries, which leads to
3876 eventual starvation where the daemon has no replyaddrs left to use.
3877 - fix comment about rndc port, that referred to the old port number.
3878 - fix that the listening socket is not closed when too many remote
3879 control connections are made at the same time.
3880 - removed ldns-src tarball inside the unbound tarball.
3882 23 June 2011: Wouter
3883 - Changed -flto check to support clang compiler.
3884 - tag 1.4.11rc3 created.
3886 17 June 2011: Wouter
3887 - tag 1.4.11rc1 created.
3888 - remove warning about signed/unsigned from flex (other flex version).
3889 - updated aclocal.m4 and libtool to match.
3890 - tag 1.4.11rc2 created.
3892 16 June 2011: Wouter
3893 - log-queries: yesno option, default is no, prints querylog.
3894 - version is 1.4.11.
3896 14 June 2011: Wouter
3897 - Use -flto compiler flag for link time optimization, if supported.
3898 - iana portlist updated.
3900 12 June 2011: Wouter
3901 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
3903 10 June 2011: Wouter
3904 - unbound-control has version number in the header,
3905 UBCT[version]_space_ is the header sent by the client now.
3906 - Unbound control port number is registered with IANA:
3907 ub-dns-control 8953/tcp unbound dns nameserver control
3908 This is the new default for the control-port config setting.
3909 - statistics-interval prints the number of jostled queries to log.
3912 - Fix Makefile for U in environment, since wrong U is more common than
3913 deansification necessity.
3914 - iana portlist updated.
3915 - updated ldns tarball to 1.6.10rc2 snapshot of today.
3918 - Fix assertion failure when unbound generates an empty error reply
3919 in response to a query, CVE-2011-1922 VU#531342.
3920 - This fix is in tag 1.4.10.
3921 - defense in depth against the above bug, an error is printed to log
3922 instead of an assertion failure.
3925 - bug#386: --enable-allsymbols option links all binaries to libunbound
3926 and reduces install size significantly.
3927 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
3928 - iana portlist updated.
3929 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
3931 14 April 2011: Wouter
3932 - configure created with newer autoconf 2.66.
3934 12 April 2011: Wouter
3935 - bug#378: Fix that configure checks for ldns_get_random presence.
3937 8 April 2011: Wouter
3938 - iana portlist updated.
3939 - queries with CD flag set cause DNSSEC validation, but the answer is
3940 not withheld if it is bogus. Thus, unbound will retry if it is bad
3941 and curb the TTL if it is bad, thus protecting the cache for use by
3942 downstream validators.
3943 - val-override-date: -1 ignores dates entirely, for NTP usage.
3945 29 March 2011: Wouter
3946 - harden-below-nxdomain: changed so that it activates when the
3947 cached nxdomain is dnssec secure. This avoids backwards
3948 incompatibility because those old servers do not have dnssec.
3950 24 March 2011: Wouter
3951 - iana portlist updated.
3955 17 March 2011: Wouter
3956 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
3957 Applied but did not do the --disable-gost.

3965 1 March 2011: Wouter
3966 - Fix no ADflag for NXDOMAIN in NSEC3 optout. And wildcard in optout.
3967 - give config parse error for multiple names on a stub or forward zone.
3968 - updated ldns tarball to 1.6.9(todays snapshot).
3970 24 February 2011: Wouter
3971 - bug #361: Fix, time.elapsed variable not reset with stats_noreset.
3973 23 February 2011: Wouter
3974 - iana portlist updated.
3975 - common.sh to version 3.
3977 18 February 2011: Wouter
3978 - common.sh in testdata updated to version 2.
3980 15 February 2011: Wouter
3981 - Added explicit note on unbound-anchor usage:
3982 Please note usage of unbound-anchor root anchor is at your own risk
3983 and under the terms of our LICENSE (see that file in the source).
3985 11 February 2011: Wouter
3986 - iana portlist updated.
3987 - tpkg updated with common.sh for common functionality.
3989 7 February 2011: Wouter
3990 - Added regression test for addition of a .net DS to the root, and
3991 cache effects with different TTL for glue and DNSKEY.
3992 - iana portlist updated.

3995 - Fix remove private address does not throw away entire response.
3997 24 January 2011: Wouter
4000 19 January 2011: Wouter
4001 - fix bug#349: no -L/usr for ldns.
4003 18 January 2011: Wouter
4004 - ldns 1.6.8 tarball included.
4007 17 January 2011: Wouter
4008 - add get and set option for harden-below-nxdomain feature.
4009 - iana portlist updated.
4011 14 January 2011: Wouter
4012 - Fix so a changed NS RRset does not get moved name stuck on old
4013 server, for type NS the TTL is not increased.
4015 13 January 2011: Wouter
4016 - Fix prefetch so it does not get stuck on old server for moved names.
4018 12 January 2011: Wouter
4019 - iana portlist updated.
4021 11 January 2011: Wouter
4022 - Fix insecure CNAME sequence marked as secure, reported by Bert

4029 - bug#346: remove ITAR scripts from contrib, the service is discontinued, use the root.
4030 - iana portlist updated.
4032 23 December 2010: Wouter
4033 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
4035 21 December 2010: Wouter
4036 - algorithm compromise protection using the algorithms signalled in
4037 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
4038 and thus, if you have multiple algorithms in your trust-anchor-file
4039 then it will now behave different than before. Also, 5011 rollover
4040 for algorithms needs to be double-signature until the old algorithm
4042 It is not an option, because I see no use to turn the security off.
4043 - iana portlist updated.
4045 17 December 2010: Wouter
4046 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
4047 - fix validation in this case: CNAME to nodata for co-hosted opt-in
4048 NSEC3 insecure delegation, was bogus, fixed to be insecure.
4050 16 December 2010: Wouter

4067 18 November 2010: Wouter
4068 - harden-below-nxdomain option, default off (because very old
4069 software may be incompatible). We could enable it by default in
4072 17 November 2010: Wouter
4073 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
4074 - make test output nicer.
4076 15 November 2010: Wouter
4077 - silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
4078 - iana portlist updated.
4079 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
4081 9 November 2010: Wouter
4082 - unbound-anchor compiles with openssl 0.9.7.
4084 8 November 2010: Wouter
4085 - release tag 1.4.7.

4098 2 November 2010: Wouter
4102 1 November 2010: Wouter

4105 27 October 2010: Wouter
4106 - Fix uninit value in dump_infra print.
4107 - Fix validation failure for parent and child on same server with an
4108 insecure childzone and a CNAME from parent to child.
4109 - Configure detects libev-4.00.
4111 26 October 2010: Wouter
4112 - dump_infra and flush_infra commands for unbound-control.
4113 - no timeout backoff if meanwhile a query succeeded.
4114 - Change of timeout code. No more lost and backoff in blockage.
4115 At 12sec timeout (and at least 2x lost before) one probe per IP
4116 is allowed only. At 120sec, the IP is blocked. After 15min, a
4117 120sec entry has a single retry packet.
4119 25 October 2010: Wouter
4120 - Configure errors if ldns is not found.
4122 22 October 2010: Wouter
4123 - Windows 7 fix for the installer.
4125 21 October 2010: Wouter
4126 - Fix bug where fallback_tcp causes wrong roundtrip and edns
4127 observation to be noted in cache. Fix bug where EDNSprobe halted
4128 exponential backoff if EDNS status unknown.
4129 - new unresponsive host method, exponentially increasing block backoff.
4130 - iana portlist updated.
4132 20 October 2010: Wouter
4133 - interface automatic works for some people with ip6 disabled.
4134 Therefore the error check is removed, so they can use the option.
4136 19 October 2010: Wouter
4137 - Fix for request list growth, if a server has long timeout but the
4138 lost counter is low, then its effective rtt is the one without
4139 exponential backoff applied. Because the backoff is not working.
4140 The lost counter can then increase and the server is blacklisted,
4141 or the lost counter does not increase and the server is working
4144 18 October 2010: Wouter
4145 - iana portlist updated.
4147 13 October 2010: Wouter
4148 - Fix TCP so it uses a random outgoing-interface.
4149 - unbound-anchor handles ADDPEND keystate.
4151 11 October 2010: Wouter
4152 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
4153 the zone has a secure delegation hosted on the same server did not
4154 verify as secure (it was insecure by mistake).
4155 - iana portlist updated.
4156 - ldns tarball updated (for reading cachedumps with bad RR data).
4158 1 October 2010: Wouter
4159 - test for unbound-anchor. fix for reading certs.
4160 - Fix alloc_reg_release for longer uptime in out of memory conditions.
4162 28 September 2010: Wouter
4163 - unbound-anchor working, it creates or updates a root.key file.
4164 Use it before you start the validator (e.g. at system boot time).
4166 27 September 2010: Wouter
4167 - iana portlist updated.
4169 24 September 2010: Wouter
4170 - bug#329: in example.conf show correct ipv4 link-local 169.254/16.
4172 23 September 2010: Wouter
4173 - unbound-anchor app, unbound requires libexpat (xml parser library).
4175 22 September 2010: Wouter
4176 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
4177 reverse ipv6 orchid prefix from builtin list.
4178 - iana portlist updated.
4180 17 September 2010: Wouter
4181 - DLV has downgrade protection again, because the RFC says so.
4182 - iana portlist updated.
4184 16 September 2010: Wouter
4185 - Algorithm rollover operational reality intrudes, for trust-anchor,
4186 5011-store, and DLV-anchor if one key matches it's good enough.
4187 - iana portlist updated.
4188 - Fix reported validation error in out of memory condition.
4190 15 September 2010: Wouter
4191 - Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
4193 14 September 2010: Wouter
4194 - increased mesh-max-activation from 1000 to 3000 for crazy domains
4195 like _tcp.slb.com with 262 servers.
4196 - iana portlist updated.
4198 13 September 2010: Wouter
4199 - bug#327: Fix for cannot access stub zones until the root is primed.
4201 9 September 2010: Wouter
4202 - unresponsive servers are not completely blacklisted (because of
4203 firewalls), but also not probed all the time (because of the request
4204 list size it generates). The probe rate is 1%.
4205 - iana portlist updated.
4207 20 August 2010: Wouter
4208 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
4209 iterator get_mem includes priv_get_mem. delegpt nodup removed.
4210 listen_pushback, query_info_allocqname, write_socket, send_packet,
4211 comm_point_set_cb_arg and listen_resume removed.
4213 19 August 2010: Wouter
4214 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
4215 Delegpt structures checked for duplicates always.
4216 No more nameserver lookups generated when depth is full anyway.
4217 - example.conf notes how to do DNSSEC validation and track the root.
4218 - iana portlist updated.
4220 18 August 2010: Wouter
4221 - Fix bug#322: configure does not respect CFLAGS on Solaris.
4222 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
4223 if use sun-cc, but some systems need different flags.
4225 16 August 2010: Wouter
4226 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
4227 changes, uses m4_bpatsubst now.
4228 - make test (or make check) should be more portable and run the unit
4229 test and testbound scripts. (make longtest has special requirements).
4231 13 August 2010: Wouter
4232 - More pleasant remote control command parsing.
4233 - documentation added for return values reported by doxygen 1.7.1.
4234 - iana portlist updated.
4236 9 August 2010: Wouter
4237 - Fix name of rrset printed that failed validation.
4239 5 August 2010: Wouter
4240 - Return NXDOMAIN after chain of CNAMEs ends at name-not-found.
4242 4 August 2010: Wouter
4243 - Fix validation in case a trust anchor enters into a zone with
4244 unsupported algorithms.
4246 3 August 2010: Wouter

4248 - release tag 1.4.6.
4249 - trunk becomes 1.4.7 develop.
4250 - iana portlist updated.
4252 22 July 2010: Wouter
4253 - more error details on failed remote control connection.
4255 15 July 2010: Wouter
4256 - rlimit adjustments for select and ulimit can happen at the same time.
4258 14 July 2010: Wouter
4259 - Donation text added to README.
4260 - Fix integer underflow in prefetch ttl creation from cache. This
4261 fixes a potential negative prefetch ttl.
4263 12 July 2010: Wouter
4264 - Changed the defaults for num-queries-per-thread/outgoing-range.
4265 For builtin-select: 512/960, for libevent 1024/4096 and for
4266 windows 24/48 (because of win api). This makes the ratio this way
4267 to improve resilience under heavy load. For high performance, use
4268 libevent and possibly higher numbers.
4270 10 July 2010: Wouter
4271 - GOST enabled if SSL is recent and ldns has GOST enabled too.
4272 - ldns tarball updated.
4275 - iana portlist updated.
4276 - Fix validation of qtype DNSKEY when a key-cache entry exists but
4277 no rr-cache entry is used (it expired or prefetch), it then goes
4278 back up to the DS or trust-anchor to validate the DNSKEY.
4281 - Neat function prototypes, unshadowed local declarations.
4284 - failure to chown the pidfile is not fatal any more.
4285 - testbound uses UTC timezone.
4286 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
4287 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
4290 - log if a server is skipped because it is on the donotquery list,
4291 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
4292 - added feature to print configure date, target and options with -h.
4293 - added feature to print event backend system details with -h.
4294 - wdiff is not actually required by make test, updated requirements.
4297 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
4298 must be signed with all algorithms from the DS rrset at the parent.
4299 This is now checked and becomes bogus if not.
4301 28 June 2010: Wouter
4302 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
4303 in overload situations to be about 5 qps for the class of shortly
4305 The capacity of the resolver is then about (numqueriesperthread / 2)
4306 / (average time for such long queries) qps for long queries.
4307 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
4308 qps for short queries, per thread.
4309 - Fix the max number of reply-address count to be applied for duplicate
4310 queries, and not for new query list entries. This raises the memory
4311 usage to a max of (16+1)*numqueriesperthread reply addresses.
4313 25 June 2010: Wouter
4314 - Fix handling of corner case reply from lame server, follows rfc2308.
4315 It could lead to a nodata reply getting into the cache if the search
4316 for a non-lame server turned up other misconfigured servers.
4317 - unbound.h has extern "C" statement for easier include in c++.
4319 23 June 2010: Wouter
4320 - iana portlist updated.
4321 - makedist upgraded cross compile openssl option, like this:
4322 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
4324 22 June 2010: Wouter
4325 - Unbound reports libev or libevent correctly in logs in verbose mode.
4326 - Fix to unload gost dynamic library module for leak testing.
4328 18 June 2010: Wouter
4329 - iana portlist updated.
4331 17 June 2010: Wouter
4332 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
4334 16 June 2010: Wouter
4335 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
4336 assertion was wrong.
4337 - updated ldns tarball.
4339 15 June 2010: Wouter
4340 - tag 1.4.5 created.
4341 - trunk contains 1.4.6 in development.
4342 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
4343 - Fix to use one pointer less for iterator query state store_parent_NS.
4344 - makedist crosscompile to windows uses builtin ldns not host ldns.
4345 - Max referral count from 30 to 130, because 128 one character domains
4347 - added documentation for the histogram printout to syslog.
4349 11 June 2010: Wouter
4350 - When retry to parent the retrycount is not wiped, so failed
4351 nameservers are not tried again.
4352 - iana portlist updated.
4354 10 June 2010: Wouter
4355 - Fix bug where a long loop could be entered, now cycle detection
4356 has a loop-counter and maximum search amount.
4359 - iana portlist updated.
4360 - 1.4.5rc1 tag created.
4363 - ldns tarball updated, 1.6.5.
4364 - review comments, split dependency cycle tracking for parentside
4365 last resort lookups for A and AAAA so there are more lookup options.
4368 - Fix compile warning if compiled without threads.
4369 - updated ldns-tarball with current ldns svn (pre 1.6.5).
4370 - GOST disabled-by-default, the algorithm number is allocated but the
4371 RFC is still has to pass AUTH48 at the IETF.
4374 - Ignore Z flag in incoming messages too.
4375 - Fix storage of negative parent glue if that last resort fails.
4376 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
4377 - new splint flags for newer splint install.
4380 - Fix AD flag handling, it could in some cases mistakenly copy the AD
4381 flag from upstream servers.
4382 - alloc_special_obtain out of memory is not a fatal error any more,
4383 enabling unbound to continue longer in out of memory conditions.
4384 - parentside names are dispreferred but not said to be dnssec-lame.
4385 - parentside check for cached newname glue.
4386 - fix parentside and querytargets modulestate, for dump_requestlist.
4387 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
4388 - fix parentside from cache to be marked dispreferred for bad names.
4391 - iana portlist updated.
4392 - parent-child disagreement approach altered. Older fixes are
4393 removed in place of a more exhaustive search for misconfigured data
4394 available via the parent of a delegation.
4395 This is designed to be throttled by cache entries, with TTL from the
4396 parent if possible. Additionally the loop-counter is used.
4397 It also tests for NS RRset differences between parent and child.
4398 The fetch of misconfigured data should be more reliable and thorough.
4399 It should work reliably even with no or only partial data in cache.
4400 Data received from the child (as always) is deemed more
4401 authoritative than information received from the delegation parent.
4402 The search for misconfigured data is not performed normally.
4405 - Contribution from Migiel de Vos (Surfnet): nagios patch for
4406 unbound-host, in contrib/ (in the source tarball). Makes
4407 unbound-host suitable for monitoring dnssec(-chain) status.
4410 - EDNS timeout code will not fire if EDNS status already known.
4411 - EDNS failure not stored if EDNS status known to work.
4414 - Fix resolution for domains like safesvc.com.cn. If the iterator
4415 can not recurse further and it finds the delegation in a state
4416 where it would otherwise have rejected it outhand if so received
4417 from a cache lookup, then it can try to ask higherup (with loop
4419 - Fix comments in iter_utils:dp_is_useless.
4422 - Fix various compiler warnings from the clang llvm compiler.
4423 - iana portlist updated.
4426 - Fix bug#308: spelling error in variable name in parser and lexer.
4429 - Fix dnssec-missing detection that was turned off by server selection.
4430 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
4431 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
4432 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
4434 29 April 2010: Wouter
4435 - Fix for dnssec lameness detection to use the key cache.
4436 - infra cache entries that are expired are wiped clean. Previously
4437 it was possible to not expire host data (if accessed often).
4439 28 April 2010: Wouter
4440 - ldns tarball updated and GOST support is detected and then enabled.
4441 - iana portlist updated.
4442 - Fix detection of gost support in ldns (reported by Chris Smith).
4444 27 April 2010: Wouter
4445 - unbound-control get_option domain-insecure shows config file items.
4446 - fix retry sequence if prime hints are recursion-lame.
4447 - autotrust anchor file can be initialized with a ZSK key as well.
4448 - harden-referral-path does not result in failures due to max-depth.
4449 You can increase the max-depth by adding numbers (' 0') after the
4450 target-fetch-policy, this increases the depth to which is checked.
4452 26 April 2010: Wouter
4453 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
4454 CPPFLAGS during configure process.
4455 - if libev is installed on the base system (not libevent), detect
4456 it from the event.h header file and link with -lev.
4457 - configlexer.lex gets config.h, and configyyrename.h added by make,
4458 no more double include.
4459 - More strict scrubber (Thanks to George Barwood for the idea):
4460 NS set must be pertinent to the query (qname subdomain nsname).
4461 - Fix bug#307: In 0x20 backoff fix fallback so the number of
4462 outstanding queries does not become -1 and block the request.
4463 Fixed handling of recursion-lame in combination with 0x20 fallback.
4464 Fix so RRsets are compared canonicalized and sorted if the immediate
4465 comparison fails, this makes it work around round-robin sites.
4467 23 April 2010: Wouter
4468 - Squelch log message: sendto failed permission denied for
4469 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
4470 - Fix to fetch data as last resort more tenaciously. When cycle
4471 targets cause the server selection to believe there are more options
4472 when they really are not there, the server selection is reinitiated.
4473 - Fix fetch from blacklisted dnssec lame servers as last resort. The
4474 server's IP address is then given in validator errors as well.
4475 - Fix local-zone type redirect that did not use the query name for
4478 22 April 2010: Wouter
4480 - trunk contains 1.4.5 in development.
4481 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
4482 The validator error message was 'no signatures from ...'.
4484 16 April 2010: Wouter
4485 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
4488 15 April 2010: Wouter
4489 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
4490 example key and signatures for GOST. GOST requires openssl-1.0.0.
4491 GOST is still disabled by default.
4493 9 April 2010: Wouter
4494 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
4495 get into an endless loop, if 0x20 was enabled, and buffers are small
4496 or particular broken packets are received.
4497 - Fix chain of trust with CNAME at an intermediate step, for the DS
4500 8 April 2010: Wouter
4501 - Fix validation of queries with wildcard names (*.example).
4503 6 April 2010: Wouter
4504 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
4505 cache timeout coincided with a server update, the current EDNS
4506 backoff is less sensitive, and does not cache the backoff unless
4507 the backoff actually works and the domain is not expecting DNSSEC.
4508 - GOST support with correct algorithm numbers.
4510 1 April 2010: Wouter
4511 - iana portlist updated.
4513 24 March 2010: Wouter
4514 - unbound control flushed items are not counted when flushed again.
4516 23 March 2010: Wouter
4517 - iana portlist updated.
4519 22 March 2010: Wouter
4520 - unbound-host disables use-syslog from config file so that the
4521 config file for the main server can be used more easily.
4522 - fix bug#301: unbound-checkconf could not parse interface
4523 '0.0.0.0@5353', even though unbound itself worked fine.
4525 19 March 2010: Wouter
4526 - fix fwd_ancil test to pass if the socket options are not supported.
4528 18 March 2010: Wouter
4529 - Fixed random numbers for port, interface and server selection.
4530 Removed very small bias.
4531 - Refer to the listing in unbound-control man page in the extended
4532 statistics entry in the unbound.conf man page.
4534 16 March 2010: Wouter
4535 - Fix interface-automatic for OpenBSD: msg.controllen was too small,
4536 also assertions on ancillary data buffer.
4537 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
4538 - for NSEC3 check if signatures are cached.
4540 15 March 2010: Wouter
4541 - unit test for util/regional.c.
4543 12 March 2010: Wouter
4544 - Reordered configure checks so fork and -lnsl -lsocket checks are
4545 earlier, and thus later checks benefit from and do not hinder them.
4546 - iana portlist updated.
4547 - ldns tarball updated.
4548 - Fix python use when multithreaded.
4549 - Fix solaris python compile.
4550 - Include less in config.h and include per code file for ldns, ssl.
4552 11 March 2010: Wouter
4553 - another memory allocation option: --enable-alloc-nonregional.
4554 exposes the regional allocations to other memory purifiers.
4555 - fix for memory alignment in struct sock_list allocation.
4556 - Fix for MacPorts ldns without ssl default, unbound checks if ldns
4557 has dnssec functionality and uses the builtin if not.
4558 - Fix daemonize on Solaris 10, it did not detach from terminal.
4559 - tag 1.4.3 created.
4560 - trunk is 1.4.4 in development.
4561 - spelling fix in validation error involving cnames.
4563 10 March 2010: Wouter
4564 - --enable-alloc-lite works with test set.
4565 - portability in the testset: printf format conversions, prototypes.
4567 9 March 2010: Wouter
4568 - tag 1.4.2 created.
4569 - trunk is 1.4.3 in development.
4570 - --enable-alloc-lite debug option.
4572 8 March 2010: Wouter
4573 - iana portlist updated.
4575 4 March 2010: Wouter
4576 - Fix crash in control channel code.
4578 3 March 2010: Wouter
4579 - better casts in pipe code, brackets placed wrongly.
4580 - iana portlist updated.
4582 1 March 2010: Wouter
4583 - make install depends on make all.
4584 - Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
4585 - --enable-checking: enables assertions but does not look nonproduction.
4586 - nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
4587 nxdomain and nodata distinguished.
4588 - ldns tarball updated.
4589 - --disable-rpath fixed for libtool not found errors.
4590 - new fedora specfile from Fedora13 in contrib from Paul Wouters.
4592 26 February 2010: Wouter
4593 - Fixup prototype for lexer cleanup in daemon code.
4594 - unbound-control list_stubs, list_forwards, list_local_zones and
4597 24 February 2010: Wouter
4598 - Fix scrubber bug that potentially let NS records through. Reported
4600 - Also delete potential poison references from additional.
4601 - Fix: no classification of a forwarder as lame, throw away instead.
4603 23 February 2010: Wouter
4604 - libunbound ub_ctx_get_option() added.
4605 - unbound-control set_option and get_option commands.
4606 - iana portlist updated.
4608 18 February 2010: Wouter
4609 - A little more strict DS scrubbing.
4610 - No more blacklisting of unresponsive servers, a 2 minute timeout
4612 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.
4613 - pickup ldns compile fix, libdl for libcrypto.
4614 - log 'tcp connect: connection timed out' only in high verbosity.
4615 - unbound-control log_reopen command.
4616 - moved get_option code from unbound-checkconf to util/config_file.c
4618 17 February 2010: Wouter
4619 - Disregard DNSKEY from authority section for chain of trust.
4620 DS records that are irrelevant to a referral scrubbed. Anti-poison.
4621 - iana portlist updated.
4623 16 February 2010: Wouter
4624 - Check for 'no space left on device' (or other errors) when
4625 writing updated autotrust anchors and print errno to log.
4627 15 February 2010: Wouter
4628 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
4629 hardcoded. We made the choice to send out more conservatively,
4630 protecting against an aggregate effect more than protecting a
4631 single user (from their own folly, perhaps in case of misconfig).
4633 12 February 2010: Wouter
4634 - Re-query pattern changed on validation failure. To protect troubled
4635 authority servers, unbound caches a failure for the DNSKEY or DS
4636 records for the entire zone, and only retries that 900 seconds later.
4637 This implies that only a handful of packets are sent extra to the
4638 authority if the zone fails.
4640 11 February 2010: Wouter
4641 - ldns tarball update for long label length syntax error fix.
4642 - iana portlist updated.
4644 9 February 2010: Wouter
4645 - Fixup in compat snprintf routine, %f 1.02 and %g support.
4646 - include math.h for testbound test compile portability.
4648 2 February 2010: Wouter
4649 - Updated url of IANA itar, interim trust anchor repository, in script.

4671 13 January 2010: Wouter
4672 - prefetch-key option that performs DNSKEY queries earlier in the
4673 validation process, and that could halve the latency on DNSSEC
4674 queries. It takes some extra processing (CPU, a cache is needed).
4676 12 January 2010: Wouter
4677 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
4679 8 January 2010: Wouter
4680 - Fix for parent-child disagreement code which could have trouble
4681 when (a) ipv6 was disabled and (b) the TTL for parent and child
4682 were different. There were two bugs, the parent-side information
4683 is fixed to no longer block lookup of child side information and
4684 the iterator is fixed to no longer attempt to get ipv6 when it is
4685 not enabled and then give up in failure.
4686 - test and fixes to make prefetch actually store the answer in the
4687 cache. Considers some rrsets 'already expired' but does not allow
4688 overwriting of rrsets considered more secure.
4690 7 January 2010: Wouter
4691 - Fixup python documentation (thanks Leo Vandewoestijne).
4692 - Work on cache prefetch feature.

4728 9 December 2009: Wouter
4729 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
4730 errors generated for domain names like '.example.com'.
4731 - Fix SOA excluded from negative DS responses. Reported by Hauke
4732 Lampe. The negative cache did not include proper SOA records for
4733 negative qtype DS responses which makes BIND barf on it, such
4734 responses are now only used internally.
4735 - Fix negative cache lookup of closestencloser check of DS type bit.
4737 8 December 2009: Wouter
4738 - Fix for lookup of parent-child disagreement domains, where the
4739 parent-side glue works but it does not provide proper NS, A or AAAA
4740 for itself, fixing domains such as motorcaravanners.eu.
4741 - Feature: you can specify a port number in the interface: line, so
4742 you can bind the same interface multiple times at different ports.
4744 7 December 2009: Wouter
4745 - Bug#287: Fix segfault when unbound-control remove nonexistent local
4746 data. Added check to tests.
4748 1 December 2009: Wouter

4850 the NSEC3 patch from the entry above.
4851 - val-log-level: 2 shows extended error information for validation

4853 validation failure <example.com. DNSKEY IN>: signature expired from
4854 192.0.2.4 for trust anchor example.com. while building chain of trust
4855 validation failure <www.example.com. A IN>: no signatures from
4856 192.0.2.6 for key example.com. while building chain of trust
4858 6 October 2009: Wouter
4859 - Test set updated to provide additional ns lookup result.
4860 The retry would attempt to fetch the data from other nameservers
4861 for bogus data, and this needed to be provisioned in the tests.

4887 - test unbound reading of original autotrust data.
4888 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
4889 picked up, otherwise performs initial probe like usual.
4891 22 September 2009: Wouter
4892 - autotrust test with algorithm rollover, new ordering of checks
4893 assists in orderly rollover.

4917 10 September 2009: Wouter
4918 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
4919 - use linebuffering for log-file: output, this can be significantly
4920 faster than the previous fflush method and enable some class of
4921 resolvers to use high verbosity (for short periods).
4922 Not on windows, because line buffering does not work there.
4924 9 September 2009: Wouter
4925 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
4926 The RRsets would still expire at the normal time, but this would
4927 keep messages bogus in the cache for too long.

4929 - documented that load_cache is meant for debugging.
4931 8 September 2009: Wouter

5144 in the wrong order would be parsed, but put wrongly into internal
5145 structures so that later validation would fail.
5146 - Extreme lenience for wrongly truncated replies where a positive

5184 going to higher zones when looking up the right forward or stub
5185 server. This makes a stub pointing to a local server that has
5186 a local view of example.com signed with the same keys as are
5187 publicly used work. Reported by Johan Ihren.

5189 Dennis DeDonatis. It converts /etc/hosts into config statements.
5190 - same thing fixed for forward-zone and DS, chain of trust from
5191 public internet into the forward-zone works now. Added unit test.
5194 - openssl key files are opened apache-style, when user is root and
5195 before chrooting. This makes permissions on remote-control key
5196 files easier to set up. Fixes bug #251.
5197 - flush_type and flush_name remove msg cache entries.
5198 - codereview - dp copy bogus setting fix.
5201 - Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
5202 inadvertant behaviour.
5203 - 1.3.0 tarball for release created.
5204 - 1.3.1 development in svn trunk.
5205 - iana portlist updated.

5212 - fixup bad free() when wrongly encoded DSA signature is seen.
5213 Reported by Paul Wouters.
5214 - review comments from Matthijs.
5217 - --enable-sha2 option. The draft rsasha256 changed its algorithm
5218 numbers too often. Therefore it is more prudent to disable the
5219 RSASHA256 and RSASHA512 support by default.
5220 - ldns trunk included as new tarball.
5221 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.
5224 - fixup doc bug in README reported by Matthew Dempsky.
5227 - update iana port list
5228 - update ldns lib tarball
5231 - detect lack of IPv6 support on XP (with a different error code).
5232 - Fixup a crash-on-exit which was triggered by a very long queue.
5233 Unbound would try to re-use ports that came free, but this is
5234 of course not really possible because everything is deleted.
5235 Most easily triggered on XP (not Vista), maybe because of the
5236 network stack encouraging large messages backlogs.
5237 - change in debug statements.
5238 - Fixed bug that could cause a crash if root prime failed when there
5239 were message backlogs.
5242 - Thanks again to Brett Carr, found an assertion that was not true.
5243 Assertion checked if recursion parent query still existed.
5245 29 April 2009: Wouter
5246 - Thanks to Brett Carr, caught windows resource leak, use
5247 closesocket() and not close() on sockets or else the network stack
5248 starts to leak handles.

5276 - fix rsasha512 unit test for new (interim) algorithm number.
5277 - fix test:ldns doesn't like DOS line endings in keyfiles on unix.

5293 9 April 2009: Wouter
5294 - Fix for removal of RSASHA256_NSEC3 protonumber from ldns.
5295 - ldns tarball updated.
5296 - iana portlist update.
5297 - detect GOST support in openssl-1.0.0-beta1, and fix compile problem
5298 because that openssl defines the name STRING for itself.
5300 6 April 2009: Wouter
5301 - windows compile fix.
5302 - Detect FreeBSD jail without ipv6 addresses assigned.
5303 - python libunbound wrapper unit test.

5305 from configure --with-pythonmodule:
5306 /usr/lib/python2.x/site-packages/unboundmodule.py
5307 from configure --with-pyunbound:
5308 /usr/lib/python2.x/site-packages/unbound.py
5309 /usr/lib/python2.x/site-packages/_unbound.so*
5310 The example python scripts (pythonmod/examples and
5311 libunbound/python/examples) are not installed.

5313 - clock skew checks in unbound, config statements.
5314 - nxdomain ttl considerations in requirements.txt
5316 3 April 2009: Wouter
5317 - Fixed a bug that caused messages to be stored in the cache too
5318 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
5319 targets have been more vulnerable to the TTL miscalculation bug.
5320 - documentation test fixed for python addition.
5322 2 April 2009: Wouter
5323 - pyunbound (libunbound python plugin) compiles using libtool.

5325 - iana portlist updated.
5326 - fixed bug in unbound-control flush_zone where it would not flush
5327 every message in the target domain. This especially impacted
5328 NXDOMAIN messages which could remain in the cache regardless.
5329 - python module test package.
5331 1 April 2009: Wouter
5332 - suppress errors when trying to contact authority servers that gave
5333 ipv6 AAAA records for their nameservers with ipv4 mapped contents.

5387 - defaults for windows baked into configure.ac (used if on mingw).
5389 18 March 2009: Wouter
5390 - Added tests, unknown algorithms become insecure. fallback works.
5391 - Fix for and test for unknown algorithms in a trust anchor
5392 definition. Trust anchors with no supported algos are ignored.
5393 This means a (higher)DS or DLV entry for them could succeed, and
5394 otherwise they are treated as insecure.
5395 - domain-insecure: "example.com" statement added. Sets domain
5396 insecure regardless of chain of trust DSs or DLVs. The inverse
5399 17 March 2009: Wouter
5400 - unit test for unsupported algorithm in anchor warning.
5401 - fixed so queries do not fail on opportunistic target queries.
5403 16 March 2009: Wouter

5413 - uninstaller can stop unbound - changed text on it to reflect that.
5414 - remove debugging from windows 'cron' actions.
5416 12 March 2009: Wouter
5417 - log to App.logs on windows prints executable identity.
5419 - munin plugin fix benign locking error printout.
5420 - anchor-update for windows, called every 24 hours; unbound reloads.
5422 11 March 2009: Wouter
5423 - winsock event handler resets WSAevents after signalled.
5424 - winsock event handler tests if signals are really signalled.
5425 - install and service with log to file works on XP and Vista on
5426 default install location.
5427 - on windows logging to the Application logbook works (as a service).
5428 - fix RUN_DIR on windows compile setting in makedist.
5429 - windows registry has Software\Unbound\ConfigFile element.
5430 If does not exist, the default is used. The -c switch overrides it.

5478 - unbound-checkconf and unbound print warnings when trust anchors
5479 have unsupported algorithms.
5480 - added contrib/update-itar.sh This script is similar to
5481 update-anchor.sh, and updates from the IANA ITAR repository.
5482 You can provide your own PGP key and trust repo, or can use the
5483 builtin. The program uses wget and gpg to work.
5484 - iana portlist updated.
5485 - update-itar.sh: using ftp:// urls because https godaddy certificate
5486 is not available everywhere and then gives fatal errors. The
5487 security is provided by pgp signature.
5489 18 February 2009: Wouter
5490 - more cycle detection. Also for target queries.
5491 - fixup bug where during deletion of the mesh queries the callbacks

5493 a reentrant safe state. Affects libunbound, reload of server,
5494 on quit and flush_requestlist.
5495 - iana portlist updated.
5497 13 February 2009: Wouter

5503 - updated iana portlist.
5505 12 February 2009: Wouter

5532 in the log file as Feb 06 13:45:26 (like syslog does).
5533 - detect event_base_new in libevent-1.4.1 and later and use it.
5534 - #231 unbound-checkconf -o option prints that value from config file.
5535 Useful for scripting in management scripts and the like.
5537 5 February 2009: Wouter
5538 - ldns 1.5.0 rc as tarball included.
5539 - 1.3.0 development continues:
5540 change in libunbound API: ub_cancel can return an error, that
5541 the async_id did not exist, or that it was already delivered.
5542 The result could have been delivered just before the cancel
5543 routine managed to acquire the lock, so a caller may get the
5544 result at the same time they call cancel. For this case,
5545 ub_cancel tries to return an error code.
5546 Fixes race condition in ub_cancel() libunbound function.
5547 - MacOSX Leopard cleaner text output from configure.
5548 - initgroups(3) is called to drop secondary group permissions, if
5550 - configure option --with-ldns-builtin forces the use of the
5551 inluded ldns package with the unbound source. The -I include
5552 is put before the others, so it avoids bad include files from
5553 an older ldns install.
5554 - daemon(3) posix call is used when available.
5555 - testbound test for older fix added.
5557 4 February 2009: Wouter

5566 16 January 2009: Wouter
5567 - more quiet about ipv6 network failures, i.e. when ipv6 is not
5568 available (network unreachable). Debug still printed on high
5570 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
5571 debugging with unbound-host -4 -d ...
5572 - more cycle detection for NS-check, addr-check, root-prime and
5573 stub-prime queries in the iterator. Avoids possible deadlock
5576 15 January 2009: Wouter
5577 - bug #229: fixup configure checks for compilation with Solaris
5578 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc

5581 - update testset for recent retry change.
5583 14 January 2009: Wouter
5584 - 1.2.1 feature: negative caching for failed queries.
5585 Queries that failed are cached for 5 seconds (NORR_TTL).
5586 If the failure is local, like out of memory, it is not cached.
5587 - the TTL comparison for the cache used different comparisons,
5588 causing many cache responses that used the iterator and validator
5589 state machines unnecessarily.
5590 - retry from 4 to 5 so that EDNS drop retry is part of the first
5591 query resolve attempt, and cached error does not stop EDNS fallback.
5592 - remove debug prints that protect against bad referrals.
5593 - honor QUIET=no on make commandline (or QUIET=yes ).
5595 13 January 2009: Wouter
5596 - fixed bug in lameness marking, removed printouts.
5597 - find NS rrset more cleanly for qtype NS.
5598 - Moved changes to 1.2.0 for release. Thanks to Mark Zealey for
5600 - 1.2.1 feature: stops resolving AAAAs promiscuously when they
5601 are in the negative cache.
5603 12 January 2009: Wouter
5604 - fixed bug in infrastructure lameness cache, did not lowercase
5605 name of zone to hash when setting lame.

5624 - porting testsuite; unused var warning, and type fixup.
5626 6 January 2009: Wouter
5627 - fixup packet-of-death when compiled with --enable-debug.
5628 A malformed packet could cause an internal assertion failure.
5629 - added test for HINFO canonicalisation behaviour.
5630 - fixup reported problem with transparent local-zone data where
5631 queries with different type could get nxdomain. Now queries
5632 with a different name get resolved normally, with different type
5633 get a correct NOERROR/NODATA answer.
5634 - HINFO no longer downcased for validation, making unbound compatible
5636 - fix reading included config files when chrooted.
5637 Give full path names for include files.
5638 Relative path names work if the start dir equals the working dir.
5639 - fix libunbound message transport when no packet buffer is available.
5641 5 January 2009: Wouter
5642 - fixup getaddrinfo failure handling for remote control port.
5643 - added L.ROOT-SERVERS.NET. AAAA 2001:500:3::42 to builtin root hints.
5644 - fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
5645 - comm_timer_set performs base_set operation after event_add.
5647 18 December 2008: Wouter

5665 - snapshot version uses _ not - to help rpm distinguish the
5668 11 December 2008: Wouter
5669 - better fix for bug #219: use LOG_NDELAY with openlog() call.
5670 Thanks to Tamas Tevesz.
5672 9 December 2008: Wouter
5673 - bug #221 fixed: unbound checkconf checks if key files exist if
5674 remote control is enabled. Also fixed NULL printf when not chrooted.
5675 - iana portlist updated.
5677 3 December 2008: Wouter

5686 - fixup remote control local_data addition memory corruption bug.
5688 1 December 2008: Wouter
5689 - SElinux policy files in contrib/selinux for the unbound daemon,
5690 by Paul Wouters and Adam Tkac.

5695 - fixup testcode/streamtcp to work on vista/mingw.
5696 - root-hints test checks version of dig required.
5697 - blacklisted servers are polled at a low rate (1%) to see if they
5698 come back up. But not if there is some other working server.
5700 24 November 2008: Wouter
5701 - document that the user of the server daemon needs read privileges
5702 on the keys and certificates generated by unbound-control-setup.
5703 This is different per system or distribution, usually, running the
5704 script under the same username as the server uses suffices.
5705 i.e. sudo -u unbound unbound-control-setup
5706 - testset port to vista/mingw.
5707 - tcp_sigpipe to freebsd port.
5709 21 November 2008: Wouter
5710 - fixed tcp accept, errors were printed when they should not.
5711 - unbound-control-setup.sh removes read/write permissions other
5712 from the keys it creates (as suggested by Dmitriy Demidov).
5714 20 November 2008: Wouter
5715 - fixup fatal error due to faulty error checking after tcp accept.
5716 - add check in rlimit to avoid integer underflow.
5717 - rlimit check with new formula; better estimate for number interfaces
5718 - nicer comments in rlimit check.
5719 - tag 1.1.1 created in svn.
5720 - trunk label is 1.1.2
5722 19 November 2008: Wouter
5723 - bug #219: fixed so that syslog which delays opening until the first
5724 log line is written, gets a log line while not chroot'ed yet.
5726 18 November 2008: Wouter
5727 - iana portlist updated.
5728 - removed cast in unit test debug print that was not 64bit safe.
5729 - trunk back to 1.1.0; copied to tags 1.1.0 release.
5730 - trunk to has version number 1.1.1 again.
5731 - in 1.1.1; make clean nicer. grammar in manpage.
5733 17 November 2008: Wouter
5734 - theoretical fix for problems reported on mailing list.
5735 If a delegation point has no A but only AAAA and do-ip6 is no,
5736 resolution would fail. Fixed to ask for the A and AAAA records.
5737 It has to ask for both always, so that it can fail quietly, from
5738 TLD perspective, when a zone is only reachable on one transport.
5739 - test for above, only AAAA and doip6 is no. Fix causes A record
5740 for nameserver to be fetched.
5741 - fixup address duplication on cache fillup for delegation points.
5742 - testset updated for new query answer requirements.
5744 14 November 2008: Wouter

5752 - neater comments in worker.h.
5753 - removed doc/plan and updated doc/TODO.
5754 - silenced EHOSTDOWN (verbosity 2 or higher to see it).
5755 - review comments from Jelte, Matthijs. Neater code.
5757 12 November 2008: Wouter
5758 - add unbound-control manpage to makedist replace list.
5760 11 November 2008: Wouter
5761 - unit test for negative cache, stress tests the refcounting.
5762 - fix for refcounting error that could cause fptr_wlist fatal exit
5763 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
5764 Attila Nagy for testing).
5765 - nicer comments in cachedump about failed RR to string conversion.

5781 - iana portlist updated.
5783 5 November 2008: Wouter
5784 - fixed possible memory leak in key_entry_key deletion.
5785 Would leak a couple bytes when trust anchors were replaced.
5786 - if query and reply qname overlap, the bytes are skipped not copied.
5787 - fixed file descriptor leak when messages were jostled out that
5788 had outstanding (TCP) replies.
5789 - DNAMEs used from cache have their synthesized CNAMEs initialized
5791 - fixed file descriptor leak for localzone type deny (for TCP).
5792 - fixed memleak at exit for nsec3 negative cached zones.
5793 - fixed memleak for the keyword 'nodefault' when reading config.
5794 - made verbosity of 'edns incapable peer' warning higher, so you
5795 do not get spammed by it.
5796 - caught elusive Bad file descriptor error bug, that would print the
5797 error while unnecessarily try to listen to a closed fd. Fixed.
5799 4 November 2008: Wouter
5800 - fixed -Wwrite-strings warnings that result in better code.
5802 3 November 2008: Wouter

5808 from ldns 1.4.0 (need very latest version).
5809 - updated the included ldns tarball.
5810 - proper detection of SHA256 and SHA512 functions (not just sizes).
5812 23 October 2008: Wouter
5813 - a little more debug info for failure on signer names. prints names.
5815 22 October 2008: Wouter
5816 - CFLAGS are picked up by configure from the environment.
5817 - iana portlist updated.
5818 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
5819 - new stub-prime: yesno option. Default is off, so it does not prime.
5820 can be turned on to get same behaviour as previous unbound release.
5821 - made automated test that checks if builtin root hints are uptodate.
5822 - finished draft-wijngaards-dnsext-resolver-side-mitigation
5823 implementation. The unwanted-reply-threshold can be set.
5824 - fixup so fptr_whitelist test in alloc.c works.
5826 21 October 2008: Wouter
5827 - fix update-anchors.sh, so it does not report different RR order
5828 as an update. Sorts the keys in the file. Updated copyright.
5829 - fixup testbound on windows, the command control pipe doesn't exist.
5830 - skip 08hostlib test on windows, no fork() available.
5831 - made unbound-remote work on windows.
5833 20 October 2008: Wouter
5834 - quench a log message that is debug only.
5835 - iana portlist updated.
5836 - do not query bogus nameservers. It is like nameservers that have
5837 the NS or A or AAAA record bogus are listed as donotquery.
5838 - if server selection is faced with only bad choices, it will
5839 attempt to get more options to be fetched.
5840 - changed bogus-ttl default value from 900 to 60 seconds.
5841 In anticipation that operator caused failures are more likely than
5842 actual attacks at this time. And thus repeated validation helps
5843 the operators get the problem fixed sooner. It makes validation
5844 failures go away sooner (60 seconds after the zone is fixed).
5845 Also it is likely to try different nameserver targets every minute,
5846 so that if a zone is bad on one server but not another, it is
5847 likely to pick up the 'correct' one after a couple minutes,
5848 and if the TTL is big enough that solves validation for the zone.
5849 - fixup unbound-control compilation on windows.
5851 17 October 2008: Wouter
5852 - port Leopard/G5: fixup type conversion size_t/uint32.
5853 please ranlib, stop file without symbols warning.
5854 - harden referral path now also validates the root after priming.
5855 It looks up the root NS authoritatively as well as the root servers
5856 and attemps to validate the entries.
5858 16 October 2008: Wouter
5859 - Fixup negative TTL values appearing (reported by Attila Nagy).
5861 15 October 2008: Wouter
5862 - better documentation for 0x20; remove fallback TODO, it is done.
5863 - harden-referral-path feature includes A, AAAA queries for glue,
5864 as well as very careful NS caching (only when doing NS query).
5865 A, AAAA use the delegation from the NS-query.
5867 14 October 2008: Wouter
5868 - fwd_three.tpkg test was flaky. If the three requests hit the
5869 wrong threads by chance (or bad OS) then the test would fail.
5870 Made less flaky by increasing number of retries.
5871 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
5872 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
5873 Which includes the ldns_dname_absolute fix.
5874 - fwd_three test remains flaky now that unbound does not stop
5875 listening when full. Thus, removed timeout problem.
5876 It may be serviced by three threads, or maybe by one.
5877 Mostly only useful for lock-check testing now.
5879 13 October 2008: Wouter
5880 - fixed recursion servers deployed as authoritative detection, so
5881 that as a last resort, a +RD query is sent there to get the
5883 - iana port list update.
5884 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
5886 10 October 2008: Wouter
5887 - fixup tests - the negative cache contained the correct NSEC3s for
5888 two tests that are supposed to fail to validate.
5890 9 October 2008: Wouter
5891 - negative cache caps max iterations of NSEC3 done.
5892 - NSEC3 negative cache for qtype DS works.

5899 - 0x20 fallback code. Tries 3xnumber of nameserver addresses
5900 queries that must all be the same. Sent to random nameservers.
5901 - documented choices for DoS, EDNS, 0x20.
5903 2 October 2008: Wouter
5904 - fixup unlink of pidfile.
5905 - fixup SHA256 algorithm collation code.
5906 - contrib/update-anchor.sh does not overwrite anchors if not needed.
5907 exits 0 when a restart is needed, other values if not.
5908 so, update-anchor.sh -d mydir && /etc/rc.d/unbound restart
5909 can restart unbound exactly when needed.
5911 30 September 2008: Wouter
5912 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
5913 - tests for sha256 support and downgrade resistance.
5914 - RSASHA256 and RSASHA512 support (using the draft in dnsext),
5915 using the drafted protocol numbers.
5916 - when using stub on localhost (127.0.0.1@10053) unbound works.
5917 Like when running NSD to host a local zone, on the same machine.
5918 The noprime feature. manpages more explanation. Added a test for it.
5919 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
5921 29 September 2008: Wouter
5922 - EDNS lameness detection, if EDNS packets are dropped this is
5923 detected, eventually.

6003 - do not mark unsigned additionals bogus, leave unchecked, which
6006 1 September 2008: Wouter
6007 - disallow nonrecursive queries for cache snooping by default.

6019 again. (from bugfix#199).
6020 Some errors are not written to logfile (pidfile writing, forking),
6021 and these are only visible by using the -d commandline flag.
6023 27 August 2008: Wouter
6024 - daemon(3) is causing problems for people. Reverting the patch.
6025 bug#200, and 199 and 203 contain sideline discussion on it.

6181 - skip ipv6 tests on ipv4 only hosts (requires only ipv6 localhost not
6183 - winsock event handler keeps track of sticky TCP events, that have
6184 not been fully handled yet. when interest in the event(s) resumes,
6185 they are sent again. When WOULDBLOCK is returned events are cleared.
6186 - skip tests that need signals when testing on mingw.
6188 18 June 2008: Wouter
6189 - open testbound replay files in binary mode, because fseek/ftell

6264 fixed that ./libtool is used always, you can still override
6265 manually with ./configure libtool=mylibtool or set $libtool in

6359 It will detect and convert when necessary.
6361 14 April 2008: Wouter
6362 - got update for parseunbound.pl statistics script from Kai Storbeck.
6363 - tpkg tests for udp wait list.
6364 - documented 0x20 status.
6365 - fixup chroot and checkconf, it is much smarter now.

6367 - and check first sig byte for the encoding type.
6369 11 April 2008: Wouter
6370 - random port selection out of the configged ports.
6371 - fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
6372 - removed base_port.
6373 - created 256-port ephemeral space for the OS, 59802 available.
6374 - fixup consistency of port_if out array during heavy use.
6376 10 April 2008: Wouter

6378 - added log file statistics perl script to contrib.
6379 - automatic iana ports update from makefile. 60058 available.
6381 9 April 2008: Wouter
6382 - configure can detect libev(from its build directory) when passed
6383 --with-libevent=/home/wouter/libev-3.2
6384 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
6385 - unused commpoints not listed in epoll list.
6386 - statistics-cumulative option so that the values are not reset.
6387 - config creates array of available ports, 61841 available,
6388 it excludes <1024 and iana assigned numbers.
6389 config statements to modify the available port numbers.
6391 8 April 2008: Wouter
6392 - unbound tries to set the ulimit fds when started as server.
6393 if that does not work, it will scale back its requirements.
6395 27 March 2008: Wouter
6396 - documented /dev/random symlink from chrootdir as FAQ entry.
6398 26 March 2008: Wouter
6399 - implemented AD bit signaling. If a query sets AD bit (but not DO)
6400 then the AD bit is set in the reply if the answer validated.
6401 Without including DNSSEC signatures. Useful if you have a trusted
6402 path from the client to the resolver. Follows dnssec-updates draft.
6404 25 March 2008: Wouter
6405 - implemented check that for NXDOMAIN and NOERROR answers a query
6406 section must be present in the reply (by the scrubber). And it must
6407 be equal to the question sent, at least lowercase folded.
6408 Previously this feature happened because the cache code refused
6409 to store such messages. However blocking by the scrubber makes
6410 sure nothing gets into the RRset cache. Also, this looks like a
6411 timeout (instead of an allocation failure) and this retries are
6412 done (which is useful in a spoofing situation).
6413 - RTT banding. Band size 400 msec, this makes band around zero (fast)
6414 include unknown servers. This makes unbound explore unknown servers.
6416 7 March 2008: Wouter
6417 - -C config feature for harvest program.
6418 - harvest handles CNAMEs too.
6420 5 March 2008: Wouter
6421 - patch from Hugo Koji Kobayashi for iterator logs spelling.
6423 4 March 2008: Wouter
6424 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
6425 of a cname trust chain is lower; not full answer_AA.
6426 - test for this fix.
6427 - default config file location is /usr/local/etc/unbound.
6428 Thus prefix is used to determine the location. This is also the
6429 chroot and pidfile default location.
6431 3 March 2008: Wouter
6432 - Create 0.10 svn tag.
6433 - 0.11 version in trunk.
6434 - indentation nicer.
6436 29 February 2008: Wouter
6437 - documentation update.
6438 - fixup port to Solaris of perf test tool.
6439 - updated ldns-tarball with decl-after-statement fixes.

6444 - snprintf compat update.
6445 - harvest performs lookup.
6446 - ldns-tarball update with fix for ldns_dname_label.
6447 - installs to sbin by default.
6448 - install all manual pages (unbound-host and libunbound too).
6450 27 February 2008: Wouter
6451 - option to use caps for id randomness.
6452 - config file option use-caps-for-id: yes
6453 - harvest debug tool
6455 26 February 2008: Wouter
6456 - delay utility delays TCP as well. If the server that is forwarded
6457 to has a TCP error, the delay utility closes the connection.
6458 - delay does REUSE_ADDR, and can handle a server that closes its end.
6459 - answers use casing from query.
6461 25 February 2008: Wouter
6462 - delay utility works. Gets decent thoughput too (>20000).
6464 22 February 2008: Wouter
6465 - +2% for recursions, if identical queries (except for destination
6466 and query ID) in the reply list, avoid re-encoding the answer.
6467 - removed TODO items for optimizations that do not show up in
6469 - default is now minievent - not libevent. As its faster and
6470 not needed for regular installs, only for very large port ranges.
6471 - loop check different speedup pkt-dname-reading, 1% faster for
6472 nocache-recursion check.
6473 - less hashing during msg parse, 4% for recursion.
6474 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
6475 - some speed results noted:
6476 optimization resulted in +40% for recursion (cache miss) and
6477 +70 to +80 for cache hits, and +96% for version.bind.
6478 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
6479 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
6480 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
6481 So, unbound can be about equal qps to NSD in cache hits.
6482 And about 3.4x faster than BIND in cache performance.
6483 - delay utility for testing.
6485 21 February 2008: Wouter
6486 - speedup of root-delegation message encoding by 15%.
6487 - minor speedup of compress tree_lookup, maybe 1%.
6488 - speedup of dname_lab_cmp and memlowercmp - the top functions in
6489 profiler output, maybe a couple percent when it matters.
6491 20 February 2008: Wouter
6492 - setup speec_cache for need-ldns-testns in dotests.
6493 - check number of queued replies on incoming queries to avoid overload
6495 - fptr whitelist checks are not disabled in optimize mode.
6496 - do-daemonize config file option.
6497 - minievent time share initializes time at start.
6498 - updated testdata for nsec3 new algorithm numbers (6, 7).
6499 - small performance test of packet encoding (root delegation).
6501 19 February 2008: Wouter
6502 - applied patch to unbound-host man page from Jan-Piet Mens.
6503 - fix donotquery-localhost: yes default (it erroneously was switched
6505 - time is only gotten once and the value is shared across unbound.
6506 - unittest cleans up crypto, so that it has no memory leaks.
6507 - mini_event shares the time value with unbound this results in
6508 +3% speed for cache responses and +9% for recursions.
6509 - ldns tarball update with new NSEC3 sign code numbers.
6510 - perform several reads per UDP operation. This improves performance
6511 in DoS conditions, and costs very little in normal conditions.
6512 improves cache response +50%, and recursions +10%.
6513 - modified asynclook test. because the callback from async is not
6514 in any sort of lock (and thus can use all library functions freely),
6515 this causes a tiny race condition window when the last lock is
6516 released for a callback and a new cancel() for that callback.
6517 The only way to remove this is by putting callbacks into some
6518 lock window. I'd rather have the small possibility of a callback
6519 for a cancelled function then no use of library functions in
6520 callbacks. Could be possible to only outlaw process(), wait(),
6521 cancel() from callbacks, by adding another lock, but I'd rather not.
6523 18 February 2008: Wouter
6524 - patch to unbound-host from Jan-Piet Mens.
6525 - unbound host prints errors if fails to configure context.
6526 - fixup perf to resend faster, so that long waiting requests do
6527 not hold up the queue, they become lost packets or SERVFAILs,
6528 or can be sent a little while later (i.e. processing time may
6529 take long, but throughput has to be high).
6530 - fixup iterator operating in no cache conditions (RD flag unset
6532 - streamlined code for RD flag setting.
6533 - profiled code and changed dname compares to be faster.
6534 The speedup is about +3% to +8% (depending on the test).
6535 - minievent tests for eintr and eagain.
6537 15 February 2008: Wouter
6538 - added FreeBSD rc.d script to contrib.
6539 - --prefix option for configure also changes directory: pidfile:
6540 and chroot: defaults in config file.
6541 - added cache speed test, for cache size OK and cache too small.
6543 14 February 2008: Wouter
6544 - start without a config file (will complain, but start with
6546 - perf test program works.

6568 - unbound replies to multiple TCP queries on a TCP channel.
6569 - fixup misclassification of root referral with NS in answer
6570 when validating a nonrec query.
6572 - layout of manpages, spelling fix in header, manpages process by
6573 makedist, list asynclook and tcpstream tests as ldns-testns
6576 7 February 2008: Wouter
6577 - moved up all current level 2 to be level 3. And 3 to 4.
6578 to make room for new debug level 2 for detailed information
6580 - verbosity level 2. Describes recursion and validation.
6581 - cleaner configure script and fixes for libevent solaris.
6582 - signedness for log output memory sizes in high verbosity.
6584 6 February 2008: Wouter
6585 - clearer explanation of threading configure options.
6586 - fixup asynclook test for nothreading (it creates only one process
6587 to do the extended test).
6588 - changed name of ub_val_result_free to ub_val_resolve_free.
6589 - removes warning message during library linking, renamed
6590 libunbound/unbound.c -> libunbound.c and worker to libworker.
6591 - fallback without EDNS if result is NOTIMPL as well as on FORMERR.
6593 5 February 2008: Wouter

6597 - fixup Makefile strip command and libunbound docs typo.
6599 31 January 2008: Wouter
6600 - bg thread/process reads and writes the pipe nonblocking all the time
6601 so that even if the pipe is buffered or so, the bg thread does not
6602 block, and services both pipes and queries.
6604 30 January 2008: Wouter
6605 - check trailing / on chrootdir in checkconf.
6606 - check if root hints and anchor files are in chrootdir.
6607 - no route to host tcp error is verbosity level 2.
6608 - removed unused send_reply_iov. and its configure check.
6609 - added prints of 'remote address is 1.2.3.4 port 53' to errors
6610 from netevent; the basic socket errors.
6612 28 January 2008: Wouter
6613 - fixup uninit use of buffer by libunbound (query id, flags) for
6615 - fixup uninit warning from random.c; also seems to fix sporadic
6616 sigFPE coming out of openssl.
6617 - made openssl entropy warning more silent for library use. Needs
6619 - fixup forgotten locks for rbtree_searches on ctx->query tree.

6633 - asynclook -b blocking mode and test.
6634 - refactor asynclook, nicer code.
6635 - fixup race problems from opensll in rand init from library, with
6636 a mutex around the rand init.
6637 - fix pass async_id=NULL to _async resolve().
6638 - rewrote _wait() routine, so that it is threadsafe.
6639 - cancelation is threadsafe.
6640 - asynclook extended test in tpkg.
6641 - fixed two races where forked bg process waits for (somehow shared?)
6642 locks, so does not service the query pipe on the bg side.
6643 Now those locks are only held for fg_threads and for bg_as_a_thread.
6645 24 January 2008: Wouter
6646 - tested the cancel() function.

6657 - libunbound QUIT setup, remove memory leaks, when using threads
6658 will share memory for passing results instead of writing it over
6659 the pipe, only writes ID number over the pipe (towards the handler
6660 thread that does process() ).
6662 22 January 2008: Wouter
6663 - library code for async in libunbound/unbound.c.
6664 - fix link testbound.
6665 - fixup exit bug in mini_event.
6666 - background worker query enter and result functions.

6668 hostaddresses (A records) at the same time.
6670 21 January 2008: Wouter
6671 - libworker work, netevent raw commpoints, write_msg, serialize.
6673 18 January 2008: Wouter
6674 - touch up of manpage for libunbound.
6675 - support for IP_RECVDSTADDR (for *BSD ip4).
6676 - fix for BSD, do not use ip4to6 mapping, make two sockets, once
6677 ip6 and once ip4, uses socket options.
6678 - goodbye ip4to6 mapping.
6679 - update ldns-testpkts with latest version from ldns-trunk.
6680 - updated makedist for relative ldns pathnames.

6690 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
6692 16 January 2008: Wouter
6693 - incoming queries to the server with TC bit on are replied FORMERR.
6694 - interface-automatic replied the wrong source address on localhost
6695 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
6696 to use ifnum=-1 to mean 'no interface, use kernel route'.
6698 15 January 2008: Wouter
6699 - interface-automatic feature. experimental. Nice for anycast.
6700 - tpkg test for ip6 ancillary data.
6701 - removed debug prints.
6702 - porting experience, define for Solaris, test refined for BSD
6703 compatibility. The feature probably will not work on OpenBSD.
6704 - makedist fixup for ldns-src in build-dir.
6706 14 January 2008: Wouter
6707 - in no debug sets NDEBUG to remove asserts.

6716 - added text describing the use of stub zones for private zones.
6717 - checkconf tests for bad hostnames (IP address), and for doubled
6719 - memory sizes can be given with 'k', 'Kb', or M or G appended.
6721 10 January 2008: Wouter
6722 - typo in example.conf.
6723 - made using ldns-src that is included the package more portable
6724 by linking with .lo instead of .o files in the ldns package.
6725 - nicer do-ip6: yes/no documentation.
6726 - nicer linking of libevent .o files.
6727 - man pages render correctly on solaris.
6729 9 January 2008: Wouter
6730 - fixup openssl RAND problem, when the system is not configured to
6731 give entropy, and the rng needs to be seeded.
6733 8 January 2008: Wouter
6734 - print median and quartiles with extensive logging.
6736 4 January 2008: Wouter
6737 - document misconfiguration in private network.
6739 2 January 2008: Wouter
6740 - fixup typo in requirements.
6741 - document that 'refused' is a better choice than 'drop' for
6742 the access control list, as refused will stop retries.
6744 7 December 2007: Wouter
6745 - unbound-host has a -d option to show what happens. This can help
6746 with debugging (why do I get this answer).
6747 - fixup CNAME handling, on nodata, sets and display canonname.
6748 - dot removed from CNAME display.
6749 - respect -v for NXDOMAINs.
6750 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
6751 - size_t to int for portability of the header file.
6752 - fixup bogus handling.
6753 - dependencies and lint for unbound-host.
6755 6 December 2007: Wouter
6756 - library resolution works in foreground mode, unbound-host app
6758 - unbound-host prints rdata using ldns.
6759 - unbound-host accepts trust anchors, and prints validation
6760 information when you give -v.
6762 5 December 2007: Wouter
6763 - locking in context_new() inside the function.
6764 - setup of libworker.
6766 4 December 2007: Wouter
6767 - minor Makefile fixup.
6768 - moved module-stack code out of daemon/daemon into services/modstack,
6769 preparing for code-reuse.
6770 - move context into own header file.
6771 - context query structure.
6772 - removed unused variable pwd from checkconf.
6773 - removed unused assignment from outside netw.
6774 - check timeval length of string.
6775 - fixup error in val_utils getsigner.
6776 - fixup same (*var) error in netblocktostr.
6777 - fixup memleak on parse error in localzone.
6778 - fixup memleak on packet parse error.
6779 - put ; after union in parser.y.
6780 - small hardening in iter_operate against iq==NULL.
6781 - hardening, if error reply with rcode=0 (noerror) send servfail.
6782 - fixup same (*var) error in find_rrset in msgparse, was harmless.
6783 - check return value of evtimer_add().
6784 - fixup lockorder in lruhash_reclaim(), building up a list of locked
6785 entries one at a time. Instead they are removed and unlocked.
6786 - fptr_wlist for markdelfunc.
6787 - removed is_locked param from lruhash delkeyfunc.
6788 - moved bin_unlock during bin_split purely to please.
6790 3 December 2007: Wouter
6791 - changed checkconf/ to smallapp/ to make room for more support tools.
6792 (such as unbound-host).
6793 - install dirs created with -m 755 because they need to be accessible.
6794 - library extensive featurelist added to TODO.
6795 - please doxygen, lint.
6796 - library test application, with basic functionality.
6797 - fix for building in a subdirectory.
6798 - link lib fix for Leopard.
6800 30 November 2007: Wouter
6801 - makefile that creates libunbound.la, basic file or libunbound.a
6802 when creating static executables (no libtool).
6805 29 November 2007: Wouter
6806 - 0.9 public API start.
6808 28 November 2007: Wouter
6809 - Changeup plan for 0.8 - no complication needed, a simple solution
6810 has been chosen for authoritative features.
6811 - you can use single quotes in the config file, so it is possible
6812 to specify TXT records in local data.
6813 - fixup small memory problem in implicit transparent zone creation.
6814 - test for implicit zone creation and multiple RR RRsets local data.
6815 - local-zone nodefault test.
6816 - show testbound testlist on commit.
6817 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
6818 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
6820 - nicer verbosity: 0 and 1 levels.
6821 - lower nonRDquery chance of eliciting wrongly typed validation
6822 requiring message from the cache.
6823 - fix for nonRDquery validation typing; nodata is detected when
6824 SOA record in auth section (all validation-requiring nodata messages
6825 have a SOA record in authority, so this is OK for the validator),
6826 and NS record is needed to be a referral.
6827 - duplicate checking when adding NSECs for a CNAME, and test.
6828 - created svn tag 0.8, after completing testbed tests.
6830 27 November 2007: Wouter
6831 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
6832 - set size of msgparse lookup table to 32, from 1024, so that its size
6833 is below the 2048 regional large size threshold, and does not cause
6834 a call to malloc when a message is parsed.
6835 - update of memstats tool to print number of allocation calls.
6836 This is what is taking time (not space) and indicates the avg size
6837 of the allocations as well. region_alloc stat is removed.
6839 22 November 2007: Wouter
6840 - noted EDNS in-the-middle dropping trouble as a TODO.
6841 At this point theoretical, no user trouble has been reported.
6842 - added all default AS112 zones.
6843 - answers from local zone content.
6844 * positive answer, the rrset in question
6845 * nodata answer (exist, but not that type).
6846 * nxdomain answer (domain does not exist).
6847 * empty-nonterminal answer.
6848 * But not: wildcard, nsec, referral, rrsig, cname/dname,
6849 or additional section processing, NS put in auth.
6850 - test for correct working of static and transparent and couple
6851 of important defaults (localhost, as112, reverses).
6852 Also checks deny and refuse settings.
6853 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
6855 21 November 2007: Wouter
6856 - local zone internal data setup.
6858 20 November 2007: Wouter
6859 - 0.8 - str2list config support for double string config options.
6860 - local-zone and local-data options, config storage and documentation.
6862 19 November 2007: Wouter
6863 - do not downcase NSEC and RRSIG for verification. Follows
6864 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
6865 - fixup leaking unbound daemons at end of tests.
6866 - README file updated.
6867 - nice libevent not found error.
6868 - README talks about gnu make.
6869 - 0.8: unit test for addr_mask and fixups for it.
6870 and unit test for addr_in_common().
6871 - 0.8: access-control config file element.
6872 and unit test rpl replay file.
6873 - 0.8: fixup address reporting from netevent.
6875 16 November 2007: Wouter
6876 - privilege separation is not needed in unbound at this time.
6877 TODO item marked as such.
6878 - created beta-0.7 branch for support.
6879 - tagged 0.7 for beta release.
6880 - moved trunk to 0.8 for 0.8(auth features) development.
6881 - 0.8: access control list setup.
6883 15 November 2007: Wouter
6884 - review fixups from Jelte.
6886 14 November 2007: Wouter
6887 - testbed script does not recreate configure, since its in svn now.
6888 - fixup checkconf test so that it does not test
6889 /etc/unbound/unbound.conf.
6892 13 November 2007: Wouter
6893 - remove debug print.
6894 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
6896 12 November 2007: Wouter
6897 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
6899 - bugreports to unbound-bugs@nlnetlabs.nl
6900 - fixup testbound so it exits cleanly.
6901 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
6903 9 November 2007: Wouter
6904 - took ldns snapshot in repo.
6905 - default config file is /etc/unbound/unbound.conf.
6906 If it doesn't exist, it is installed with the doc/example.conf file.
6907 The file is not deleted on uninstall.
6908 - default listening is not all, but localhost interfaces.
6910 8 November 2007: Wouter
6911 - Fixup chroot and drop user privileges.
6912 - new L root ip address in default hints.
6914 1 November 2007: Wouter
6915 - Fixup of crash on reload, due to anchors in env not NULLed after
6916 dealloc during deinit.
6917 - Fixup of chroot call. Happens after privileges are dropped, so
6918 that checking the passwd entry still works.
6919 - minor touch up of clear() hashtable function.
6920 - VERB_DETAIL prints out what chdir, username, chroot is being done.
6921 - when id numbers run out, caches are cleared, as in design notes.
6922 Tested with a mock setup with very few bits in id, it worked.
6923 - harden-dnssec-stripped: yes is now default. It insists on dnssec
6924 data for trust anchors. Included tests for the feature.
6926 31 October 2007: Wouter
6927 - cache-max-ttl config option.
6928 - building outside sourcedir works again.
6929 - defaults more secure:
6931 chroot: "/etc/unbound"
6932 The operator can override them to be less secure ("") if necessary.
6933 - fix horrible oversight in sorting rrset references in a message,
6934 sort per reference key pointer, not on referencepointer itself.
6935 - pidfile: "/etc/unbound/unbound.pid" is now the default.
6936 - tests changed to reflect the updated default.
6937 - created hashtable clear() function that respects locks.
6939 30 October 2007: Wouter
6940 - fixup assertion failure that relied on compressed names to be
6941 smaller than uncompressed names. A packet from comrite.com was seen
6942 to be compressed to a larger size. Added it as unit test.
6943 - quieter logging at low verbosity level for common tcp messages.
6944 - no greedy TTL update.
6946 23 October 2007: Wouter
6947 - fixup (grand-)parent problem for dnssec-lameness detection.
6948 - fixup tests to do additional section processing for lame replies,
6949 since the detection needs that.
6950 - no longer trust in query section in reply during dnssec lame detect.
6951 - dnssec lameness does not make the server never ever queried, but
6952 non-preferred. If no other servers exist or answer, the dnssec lame
6953 server is used; the fastest dnssec lame server is chosen.
6954 - added test then when trust anchor cannot be primed (nodata), the
6955 insecure mode from unbound works.
6956 - Fixup max queries per thread, any more are dropped.
6958 22 October 2007: Wouter
6959 - added donotquerylocalhost config option. Can be turned off for
6961 - ISO C compat changes.
6962 - detect RA-no-AA lameness, as LAME.
6963 - DNSSEC-lameness detection, as LAME.
6964 See notes in requirements.txt for choices made.
6965 - tests for lameness detection.
6966 - added all to make test target; need unbound for fwd tests.
6967 - testbound does not pollute /etc/unbound.
6969 19 October 2007: Wouter
6970 - added configure (and its files) to svn, so that the trunk is easier
6971 to use. ./configure, config.guess, config.sub, ltmain.sh,
6973 - added yacc/lex generated files, util/configlexer.c,
6974 util/configparser.c util/configparser.h, to svn.
6975 - without lex no attempt to use it.
6976 - unsecure response validation collated into one block.
6977 - remove warning about const cast of cfgfile name.
6978 - outgoing-interfaces can be different from service interfaces.
6979 - ldns-src configure is done during unbound configure and
6980 ldns-src make is done during unbound make, and so inherits the
6981 make arguments from the unbound make invocation.
6982 - nicer error when libevent problem causes instant exit on signal.
6983 - read root hints from a root hint file (like BIND does).
6985 18 October 2007: Wouter
6986 - addresses are logged with errors.
6987 - fixup testcode fake event to remove pending before callback
6988 since the callback may create new pending items.
6989 - tests updated because retries are now in iterator module.
6990 - ldns-testpkts code is checked for differences between unbound
6991 and ldns by makedist.sh.
6992 - ldns trunk from today added in svn repo for fallback in case
6993 no ldns is installed on the system.
6994 make download_ldns refreshes the tarball with ldns svn trunk.
6995 - ldns-src.tar.gz is used if no ldns is found on the system, and
6996 statically linked into unbound.
6997 - start of regional allocator code.
6998 - regional uses less memory and variables, simplified code.
6999 - remove of region-allocator.
7000 - alloc cache keeps a cache of recently released regional blocks,
7002 - make unit test cleanly free memory.
7004 17 October 2007: Wouter
7005 - fixup another cycle detect and ns-addr timeout resolution bug.
7006 This time by refusing delegations from the cache without addresses
7007 when resolving a mandatory-glue nameserver-address for that zone.
7008 We're going to have to ask a TLD server anyway; might as well be
7009 the TLD server for this name. And this resolves a lot of cases where
7010 the other nameserver names lead to cycles or are not available.
7011 - changed random generator from random(3) clone to arc4random wrapped
7012 for thread safety. The random generator is initialised with
7013 entropy from the system.
7014 - fix crash where failure to prime DNSKEY tried to print null pointer
7016 - removed some debug prints, only verb_algo (4) enables them.
7017 - fixup test; new random generator took new paths; such as one
7018 where no scripted answer was available.
7019 - mark insecure RRs as insecure.
7020 - fixup removal of nonsecure items from the additional.
7021 - reduced timeout values to more realistic, 376 msec (262 msec has
7022 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
7023 - server selection failover to next server after timeout (376 msec).
7025 16 October 2007: Wouter
7026 - no malloc in log_hex.
7027 - assertions around system calls.
7028 - protect against gethostname without ending zero.
7029 - ntop output is null terminated by unbound.
7030 - pidfile content null termination
7031 - various snprintf use sizeof(stringbuf) instead of fixed constant.
7032 - changed loopdetect % 8 with & 0x7 since % can become negative for
7033 weird negative input and particular interpretation of integer math.
7034 - dname_pkt_copy checks length of result, to protect result buffers.
7035 prints an error, this should not happen. Bad strings should have
7036 been rejected earlier in the program.
7037 - remove a size_t underflow from msgreply size func.
7039 15 October 2007: Wouter
7041 - fix IP6 TCP, wrong definition check. With test package.
7042 - fixup the fact that the query section was not compressed to,
7043 the code was there but was called by value instead of by reference.
7044 And test for the case, uses xxd and nc.
7045 - more portable ip6 check for sockaddr types.
7047 8 October 2007: Wouter
7048 - --disable-rpath option in configure for 64bit systems with
7049 several dynamic lib dirs.
7051 7 October 2007: Wouter
7052 - fixup tests for no AD bit in non-DO queries.
7053 - test that makes sure AD bit is not set on non-DO query.
7055 6 October 2007: Wouter
7056 - removed logfile open early. It did not have the proper permissions;
7057 it was opened as root instead of the user. And we cannot change user
7058 id yet, since chroot and bind ports need to be done.
7059 - callback checks for event callbacks done from mini_event. Because
7060 of deletions cannot do this from netevent. This means when using
7061 libevent the protection does not work on event-callbacks.
7062 - fixup too small reply (did not zero counts).
7063 - fixup reply no longer AD bit when query without DO bit.
7065 5 October 2007: Wouter
7066 - function pointer whitelist.
7068 4 October 2007: Wouter
7069 - overwrite sensitive random seed value after use.
7070 - switch to logfile very soon if not -d (console attached).
7071 - error messages do not reveal the trustanchor contents.
7072 - start work on function pointer whitelists.
7074 3 October 2007: Wouter
7075 - fix for multiple empty nonterminals, after multiple DSes in the
7077 - mesh checks if modules are looping, and stops them.
7078 - refetch with CNAMEd nameserver address regression test added.
7079 - fixup line count bug in testcode, so testbound prints correct line
7080 number with parse errors.
7081 - unit test for multiple ENT case.
7082 - fix for cname out of validated unsec zone.
7083 - fixup nasty id=0 reuse. Also added assertions to detect its
7084 return (the assertion catches in the existing test cases).
7086 1 October 2007: Wouter
7087 - skip F77, CXX, objC tests in configure step.
7088 - fixup crash in refetch glue after a CNAME.
7089 and protection against similar failures (with error print).
7091 28 September 2007: Wouter
7092 - test case for unbound-checkconf, fixed so it also checks the
7093 interface: statements.
7095 26 September 2007: Wouter
7096 - SIGHUP will reopen the log file.
7097 - Option to log to syslog.
7098 - please lint, fixup tests (that went to syslog on open, oops).
7099 - config check program.
7101 25 September 2007: Wouter
7102 - tests for NSEC3. Fixup bitmap checks for NSEC3.
7103 - positive ANY response needs to check if wildcard expansion, and
7104 check that original data did not exist.
7105 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
7106 delegation, for abuse of child zone apex nsec3.
7107 - create 0.5 release tag.
7109 24 September 2007: Wouter
7110 - do not make test programs by default.
7111 - But 'make test' will perform all of the tests.
7112 - Advertise builtin select libevent alternative when no libevent
7114 - signit can generate NSEC3 hashes, for generating tests.
7115 - multiple nsec3 parameters in message test.
7116 - too high nsec3 iterations becomes insecure test.
7118 21 September 2007: Wouter
7119 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
7120 - fixup testcode lock safety (port FreeBSD).
7121 - removes subscript has type char warnings (port Solaris 9).
7122 - fixup of field with format type to int (port MacOS/X intel).
7123 - added test for infinite loop case in nonRD answer validation.
7124 It was a more general problem, but hard to reproduce. When an
7125 unsigned rrset is being validated and the key fetched, the DS
7126 sequence is followed, but if the final name has no DS, then no
7127 proof is possible - the signature has been stripped off.
7129 20 September 2007: Wouter
7130 - fixup and test for NSEC wildcard with empty nonterminals.
7131 - makedist.sh fixup for svn info.
7132 - acl features request in plan.
7133 - improved DS empty nonterminal handling.
7134 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
7135 proof anyway, which succeeds in ANS failure case.
7136 - striplab protection in case it becomes -1.
7137 - plans for static and blacklist config.
7139 19 September 2007: Wouter
7140 - comments about non-packed usage.
7141 - plan for overload support in 0.6.
7142 - added testbound tests for a failed resolution from the logs
7143 and for failed prime when missing glue.
7144 - fixup so useless delegation points are not returned from the
7145 cache. Also the safety belt is used if priming fails to complete.
7146 - fixup NSEC rdata not to be lowercased, bind compat.
7148 18 September 2007: Wouter
7149 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
7150 - validator prints subtype classification for debug.
7152 17 September 2007: Wouter
7153 - NSEC3 hash cache unit test.
7154 - validator nsec3 nameerror test.
7156 14 September 2007: Wouter
7157 - nsec3 nodata proof, nods proof, wildcard proof.
7158 - nsec3 support for cname chain ending in noerror or nodata.
7159 - validator calls nsec3 proof routines if no NSECs prove anything.
7160 - fixup iterator bug where it stored the answer to a cname under
7161 the wrong qname into the cache. When prepending the cnames, the
7162 qname has to be reset to the original qname.
7164 13 September 2007: Wouter
7165 - nsec3 find matching and covering, ce proof, prove namerror msg.
7167 12 September 2007: Wouter
7168 - fixup of manual page warnings, like for NSD bugreport.
7169 - nsec3 work, config, max iterations, filter, and hash cache.
7171 6 September 2007: Wouter
7172 - fixup to find libevent on mac port install.
7173 - fixup size_t vs unsigned portability in validator/sigcrypt.
7174 - please compiler on different platforms, for unreachable code.
7176 - pthread_rwlock type is optional, in case of old pthread libs.
7178 5 September 2007: Wouter
7179 - cname, name error validator tests.
7180 - logging of qtype ANY works.
7181 - ANY type answers get RRSIG in answer section of replies (but not
7182 in other sections, unless DO bit is on).
7183 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
7184 - DS and noDS referral validation test.
7185 - if you configure many trust anchors, parent trust anchors can
7186 securely deny existence of child trust anchors, if validated.
7187 - not all *.name NSECs are present because a wildcard was matched,
7188 and *.name NSECs can prove nodata for empty nonterminals.
7189 Also, for wildcard name NSECs, check they are not from the parent
7190 zone (for wildcarded zone cuts), and check absence of CNAME bit,
7192 - configure option for memory allocation debugging.
7193 - port configure option for memory allocation to solaris10.
7195 4 September 2007: Wouter
7196 - fixup of Leakage warning when serviced queries processed multiple
7197 callbacks for the same query from the same server.
7198 - testbound removes config file from /tmp on failed exit.
7199 - fixup for referral cleanup of the additional section.
7200 - tests for cname, referral validation.
7201 - neater testbound tpkg output.
7202 - DNAMEs no longer match their apex when synthesized from the cache.
7203 - find correct signer name for DNAME responses.
7204 - wildcarded DNAME test and fixup code to detect.
7205 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
7206 So that wildcarded CNAMEs get their NSEC with them to the answer.
7207 - test for a CNAME to a DNAME to a CNAME to an answer, all from
7208 different domains, for key fetching and signature checking of
7211 3 September 2007: Wouter
7212 - Fixed error in iterator that would cause assertion failure in
7213 validator. CNAME to a NXDOMAIN response was collated into a response
7214 with both a CNAME and the NXDOMAIN rcode. Added a test that the
7215 rcode is changed to NOERROR (because of the CNAME).
7216 - timeout on tcp does not lead to spurious leakage detect.
7217 - account memory for name of lame zones, so that memory leakages does
7218 not show lame cache growth as a leakage growth.
7219 - config setting for lameness cache expressed in bytes, instead of
7221 - tool too summarize allocations per code line.
7223 31 August 2007: Wouter
7224 - can read bind trusted-keys { ... }; files, in a compatibility mode.
7225 - iterator should not detach target queries that it still could need.
7226 the protection against multiple outstanding queries is moved to a
7227 current_query num check.
7228 - validator nodata, positive, referral tests.
7229 - dname print can print '*' wildcard.
7231 30 August 2007: Wouter
7232 - fixup override date config option.
7233 - config options to control memory usage.
7234 - caught bad free of un-alloced data in worker_send error case.
7235 - memory accounting for key cache (trust anchors and temporary cache).
7236 - memory accounting fixup for outside network tcp pending waits.
7237 - memory accounting fixup for outside network tcp callbacks.
7238 - memory accounting for iterator fixed storage.
7239 - key cache size and slabs config options.
7240 - lib crypto cleanups at exit.
7242 29 August 2007: Wouter
7243 - test tool to sign rrsets for testing validator with.
7244 - added RSA and DSA test keys, public and private pairs, 512 bits.
7245 - default configuration is with validation enabled.
7246 Only a trust-anchor needs to be configured for DNSSEC to work.
7247 - do not convert to DER for DSA signature verification.
7248 - validator replay test file, for a DS to DNSKEY DSA key prime and
7251 28 August 2007: Wouter
7252 - removed double use for udp buffers, that could fail,
7253 instead performs a malloc to do the backup.
7254 - validator validates referral messages, by validating all the rrsets
7255 and stores the rrsets in the cache. Further referral (nonRD queries)
7256 replies are made from the rrset cache directly. Unless unchecked
7257 rrsets are encountered, there are then validated.
7258 - enforce that signing is done by a parent domain (or same domain).
7259 - adjust TTL downwards if rrset TTL bigger than signature allows.
7260 - permissive mode feature, sets AD bit for secure, but bogus does
7261 not give servfail (bogus is changed into indeterminate).
7262 - optimization of rrset verification. rr canonical sorting is reused,
7263 for the same rrset. canonical rrset image in buffer is reused for
7265 - if the rrset is too big (64k exactly + large owner name) the
7266 canonicalization routine will fail if it does not fit in buffer.
7267 - faster verification for large sigsets.
7268 - verb_detail mode reports validation failures, but not the entire
7269 algorithm for validation. Key prime failures are reported as
7272 27 August 2007: Wouter
7273 - do not garble the edns if a cache answer fails.
7274 - answer norecursive from cache if possible.
7275 - honor clean_additional setting when returning secure non-recursive
7277 - do not store referral in msg cache for nonRD queries.
7278 - store verification status in the rrset cache to speed up future
7280 - mark rrsets indeterminate and insecure if they are found to be so.
7281 and store this in the cache.
7283 24 August 2007: Wouter
7284 - message is bogus if unsecure authority rrsets are present.
7285 - val-clean-additional option, so you can turn it off.
7286 - move rrset verification out of the specific proof types into one
7287 routine. This makes the proof routines prettier.
7288 - fixup cname handling in validator, cname-to-positive and cname-to-
7290 - Do not synthesize DNSKEY and DS responses from the rrset cache if
7291 the rrset is from the additional section. Signatures may have
7292 fallen off the packet, and cause validation failure.
7293 - more verbose signature date errors (with the date attached).
7294 - increased default infrastructure cache size. It is important for
7295 performance, and 1000 entries are only 212k (or a 400 k total cache
7296 size). To 10000 entries (for 2M entries, 4M cache size).
7298 23 August 2007: Wouter
7299 - CNAME handling - move needs_validation to before val_new().
7300 val_new() setups the chase-reply to be an edited copy of the msg.
7301 new classification, and find signer can find for it.
7302 removal of unsigned crap from additional, and query restart for
7304 - refuse to follow wildcarded DNAMEs when validating.
7305 But you can query for qtype ANY, or qtype DNAME and validate that.
7307 22 August 2007: Wouter
7309 - review - use val_error().
7311 21 August 2007: Wouter
7312 - ANY response validation.
7313 - store security status in cache.
7314 - check cache security status and either send the query to be
7315 validated, return the query to client, or send servfail to client.
7316 Sets AD bit on validated replies.
7317 - do not examine security status on an error reply in mesh_done.
7318 - construct DS, DNSKEY messages from rrset cache.
7319 - manual page entry for override-date.
7321 20 August 2007: Wouter
7322 - validate and positive validation, positive wildcard NSEC validation.
7323 - nodata validation, nxdomain validation.
7325 18 August 2007: Wouter
7326 - process DNSKEY response in FINDKEY state.
7328 17 August 2007: Wouter
7329 - work on DS2KE routine.
7330 - val_nsec.c for validator NSEC proofs.
7331 - unit test for NSEC bitmap reading.
7332 - dname iswild and canonical_compare with unit tests.
7334 16 August 2007: Wouter
7336 - latest release libevent 1.3c and 1.3d have threading fixed.
7337 - key entry fixup data pointer and ttl absolute.
7338 - This makes a key-prime succeed in validator, with DS or DNSKEY as
7340 - fixup canonical compare byfield routine, fix bug and also neater.
7341 - fixed iterator response type classification for queries of type
7343 dig ANY gives sometimes NS rrset in AN and NS section, and parser
7344 removes the NS section duplicate. dig NS gives sometimes the NS
7345 in the answer section, as referral.
7346 - validator FINDKEY state.
7348 15 August 2007: Wouter
7349 - crypto calls to verify signatures.
7350 - unit test for rrsig verification.
7352 14 August 2007: Wouter
7353 - default outgoing ports changed to avoid port 2049 by default.
7354 This port is widely blocked by firewalls.
7355 - count infra lameness cache in memory size.
7356 - accounting of memory improved
7357 - outbound entries are allocated in the query region they are for.
7358 - extensive debugging for memory allocations.
7359 - --enable-lock-checks can be used to enable lock checking.
7360 - protect undefs in config.h from autoheaders ministrations.
7361 - print all received udp packets. log hex will print on multiple
7363 - fixed error in parser with backwards rrsig references.
7364 - mark cycle targets for iterator did not have CD flag so failed
7367 13 August 2007: Wouter
7368 - fixup makefile, if lexer is missing give nice error and do not
7369 mess up the dependencies.
7370 - canonical compare routine updated.
7371 - canonical hinfo compare.
7372 - printout list of the queries that the mesh is working on.
7374 10 August 2007: Wouter
7375 - malloc and free overrides that track total allocation and frees.
7376 for memory debugging.
7377 - work on canonical sort.
7379 9 August 2007: Wouter
7380 - canonicalization, signature checks
7381 - dname signature label count and unit test.
7382 - added debug heap size print to memory printout.
7383 - typo fixup in worker.c
7384 - -R needed on solaris.

7387 8 August 2007: Wouter
7388 - ldns _raw routines created (in ldns trunk).
7389 - sigcrypt DS digest routines
7390 - val_utils uses sigcrypt to perform signature cryptography.
7391 - sigcrypt keyset processing
7393 7 August 2007: Wouter
7394 - security status type.
7395 - security status is copied when rdata is equal for rrsets.
7396 - rrset id is updated to invalidate all the message cache entries
7397 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
7399 - val_sigcrypt file for validator signature checks.
7401 6 August 2007: Wouter
7402 - key cache for validator.
7403 - moved isroot and dellabel to own dname routines, with unit test.
7405 3 August 2007: Wouter
7407 - scrubber check section of lame NS set.
7408 - trust anchors can be in config file or read from zone file,
7409 DS and DNSKEY entries.
7410 - unit test trust anchor storage.
7411 - trust anchors converted to packed rrsets.
7412 - key entry definition.
7414 2 August 2007: Wouter
7415 - configure change for latest libevent trunk version (needs -lrt).
7416 - query_done and walk_supers are moved out of module interface.
7417 - fixup delegation point duplicates.
7418 - fixup iterator scrubber; lame NS set is let through the scrubber
7419 so that the classification is lame.
7420 - validator module exists, and does nothing but pass through,
7421 with calling of next module and return.
7424 1 August 2007: Wouter
7425 - set version to 0.5
7426 - module work for module to module interconnections.
7427 - config of modules.
7428 - detect cycle takes flags.
7430 31 July 2007: Wouter
7434 30 July 2007: Wouter
7435 - changed random state init, so that sequential process IDs are not
7436 cancelled out by sequential thread-ids in the random number seed.
7437 - the fwd_three test, which sends three queries to unbound, and
7438 unbound is kept waiting by ldns-testns for 3 seconds, failed
7439 because the retry timeout for default by unbound is 3 seconds too,
7440 it would hit that timeout and fail the test. Changed so that unbound
7441 is kept waiting for 2 seconds instead.
7443 27 July 2007: Wouter
7444 - removed useless -C debug option. It did not work.
7445 - text edit of documentation.
7446 - added doc/CREDITS file, referred to by the manpages.
7449 26 July 2007: Wouter
7450 - cycle detection, for query state dependencies. Will attempt to
7451 circumvent the cycle, but if no other targets available fails.
7452 - unit test for AXFR, IXFR response.
7453 - test for cycle detection.
7455 25 July 2007: Wouter
7456 - testbound read ADDRESS and check it.
7457 - test for version.bind and friends.
7458 - test for iterator chaining through several referrals.
7459 - test and fixup for refetch for glue. Refetch fails if glue
7460 is still not provided.
7462 24 July 2007: Wouter
7463 - Example section in config manual.
7464 - Addr stored for range and moment in replay.
7466 20 July 2007: Wouter
7467 - Check CNAME chain before returning cache entry with CNAMEs.
7468 - Option harden-glue, default is on. It will discard out of zone
7469 data. If disabled, performance is faster, but spoofing attempts
7470 become a possibility. Note that still normalize scrubbing is done,
7471 and that the potentially spoofed data is used for infrastructure
7472 and not returned to the client.
7473 - if glue times out, refetch by asking parent of delegation again.
7474 Much like asking for DS at the parent side.
7475 - TODO items from forgery-resilience draft.
7476 and on memory handling improvements.
7477 - renamed module_event_timeout to module_event_noreply.
7478 - memory reporting code; reports on memory usage after handling
7479 a network packet (not on cache replies).
7481 19 July 2007: Wouter
7482 - shuffle NS selection when getting nameserver target addresses.
7483 - fixup of deadlock warnings, yield cpu in checklock code so that
7484 freebsd scheduler selects correct process to run.
7485 - added identity and version config options and replies.
7486 - store cname messages complete answers.
7488 18 July 2007: Wouter
7489 - do not query addresses, 127.0.0.1, and ::1 by default.
7491 17 July 2007: Wouter
7492 - forward zone options in config file.
7493 - forward per zone in iterator. takes precedence over stubs.
7494 - fixup commithooks.
7495 - removed forward-to and forward-to-port features, subsumed by
7497 - fix parser to handle absent server: clause.
7498 - change untrusted rrset test to account for scrubber that is now
7499 applied during the test (which removes the poison, by the way).
7500 - feature, addresses can be specified with @portnumber, like nsd.conf.
7501 - test config files changed over to new forwarder syntax.
7503 27 June 2007: Wouter
7504 - delete of mesh does a postorder traverse of the tree.
7505 - found and fixed a memory leak. For TTL=0 messages, that would
7506 not be cached, instead the msg-replyinfo structure was leaked.
7507 - changed server selection so it will filter out hosts that are
7508 unresponsive. This is defined as a host with the maximum rto value.
7509 This means that unbound tried the host for retries up to 120 secs.
7510 The rto value will time out after host-ttl seconds from the cache.
7511 This keeps such unresolvable queries from taking up resources.
7512 - utility for keeping histogram.
7514 26 June 2007: Wouter
7515 - mesh is called by worker, and iterator uses it.
7516 This removes the hierarchical code.
7517 QueryTargets state and Finished state are merged for iterator.
7518 - forwarder mode no longer sets AA bit on first reply.
7519 - rcode in walk_supers is not needed.
7521 25 June 2007: Wouter
7523 - error encode routine for ease.
7525 22 June 2007: Wouter
7526 - removed unused _node iterator value from rbtree_t. Takes up space.
7527 - iterator can handle querytargets state without a delegation point
7528 set, so that a priming(stub) subquery error can be handled.
7529 - iterator stores if it is priming or not.
7530 - log_query_info() neater logging.
7531 - changed iterator so that it does not alter module_qstate.qinfo
7532 but keeps a chase query info. Also query_flags are not altered,
7533 the iterator uses chase_flags.
7534 - fixup crash in case no ports for the family exist.
7536 21 June 2007: Wouter
7537 - Fixup secondary buffer in case of error callback.
7538 - cleanup slumber list of runnable states.
7539 - module_subreq_depth fails to work in slumber list.
7540 - fixup query release for cached results to sub targets.
7541 - neater error for tcp connection failure, shows addr in verbose.
7542 - rbtree_init so that it can be used with preallocated memory.
7544 20 June 2007: Wouter
7545 - new -C option to enable coredumps after forking away.
7547 - fixup CNAME generation by scrubber, and memory allocation of it.
7548 - fixup deletion of serviced queries when all callbacks delete too.
7549 - set num target queries to 0 when you move them to slumber list.
7550 - typo in check caused subquery errors to be ignored, fixed.
7551 - make lint happy about rlim_t.
7552 - freeup of modules after freeup of module-states.
7553 - duplicate replies work, this uses secondary udp buffer in outnet.
7555 19 June 2007: Wouter
7556 - nicer layout in stats.c, review 0.3 change.
7557 - spelling improvement, review 0.3 change.
7558 - uncapped timeout for server selection, so that very fast or slow
7559 servers will stand out from the rest.
7560 - target-fetch-policy: "3 2 1 0 0" config setting.
7561 - fixup queries answered without RD bit (for root prime results).
7562 - refuse AXFR and IXFR requests.
7563 - fixup RD flag in error reply from iterator. fixup RA flag from
7565 - fixup encoding of very short edns buffer sizes, now sets TC bit.
7566 - config options harden-short-bufsize and harden-large-queries.
7568 18 June 2007: Wouter
7569 - same, move subqueries to slumber list when first has resolved.
7570 - fixup last fix for duplicate callbacks.
7571 - another offbyone in targetcounter. Also in Java prototype by the way.
7573 15 June 2007: Wouter
7574 - if a query asks to be notified of the same serviced query result
7575 multiple times, this will succeed. Only one callback will happen;
7576 multiple outbound-list entries result (but the double cleanup of it
7578 - when iterator moves on due to CNAME or referral, it will remove
7579 the subqueries (for other targets). These are put on the slumber
7581 - state module wait subq is OK with no new subqs, an old one may have
7582 stopped, with an error, and it is still waiting for other ones.
7583 - if a query loops, halt entire query (easy way to clean up properly).
7585 14 June 2007: Wouter
7586 - num query targets was > 0 , not >= 0 compared, so that fetch
7587 policy of 0 did nothing.
7589 13 June 2007: Wouter
7590 - debug option: configure --enable-static-exe for compile where
7591 ldns and libevent are linked statically. Default is off.
7592 - make install and make uninstall. Works with static-exe and without.
7593 installation of unbound binary and manual pages.
7594 - alignment problem fix on solaris 64.
7595 - fixup address in case of TCP error.
7597 12 June 2007: Wouter
7598 - num target queries was set to 0 at a bad time. Default it to 0 and
7599 increase as target queries are done.
7600 - synthesize CNAME and DNAME responses from the cache.
7601 - Updated doxygen config for doxygen 1.5.
7602 - aclocal newer version.
7603 - doxygen 1.5 fixes for comments (for the strict check on docs).
7605 11 June 2007: Wouter
7606 - replies on TCP queries have the address field set in replyinfo,
7607 for serviced queries, because the initiator does not know that
7608 a TCP fallback has occured.
7609 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
7610 if qtype directly queries for the type (and then only show that
7611 'unknown type' in the answer section).
7612 - fixed message parsing where rrsigs on their own would be put
7613 in the signature list over the rrsig type.
7616 - fixup error in double linked list insertion for subqueries and
7617 for outbound list of serviced queries for iterator module.
7618 - nicer printout of outgoing port selection.
7619 - fixup cname target readout.
7620 - nicer debug output.
7621 - fixup rrset counts when prepending CNAMEs to the answer.
7622 - fixup rrset TTL for prepended CNAMEs.
7623 - process better check for looping modules, and which submodule to
7625 - subreq insertion code fixup for slumber list.
7626 - VERB_DETAIL, verbosity: 2 level gives short but readable output.
7627 VERB_ALGO, verbosity: 3 gives extensive output.
7628 - fixup RA bit in cached replies.
7629 - fixup CNAME responses from the cache no longer partial response.
7630 - error in network send handled without leakage.
7631 - enable ip6 from config, and try ip6 addresses if available,
7632 if ip6 is not connected, skips to next server.
7635 - iterator state finished.
7636 - subrequests without parent store in cache and stop.
7637 - worker slumber list for ongoing promiscuous queries.
7638 - subrequest error handling.

7640 - priming gives LAME result, returns SERVFAIL.
7641 - debug routine to print dns_msg as handled by iterator.
7642 - memleak in config file stubs fixup.
7643 - more small bugs, in scrubber, query compare no ID for lookup,
7644 in dname validation for NS targets.
7645 - sets entry.key for new special allocs.
7646 - lognametypeclass can display unknown types and classes.
7649 - random selection of equally preferred nameserver targets.
7650 - reply info copy routine. Reuses existing code.
7651 - cache lameness in response handling.
7652 - do not touch qstate after worker_process_query because it may have
7653 been deleted by that routine.
7654 - Prime response state.
7655 - Process target response state.
7656 - some memcmp changed to dname_compare for case preservation.
7659 - normalize incoming messages. Like unbound-java, with CNAME chain
7660 checked, DNAME checked, CNAME's synthesized, glue checked.
7661 - sanitize incoming messages.
7662 - split msgreply encode functions into own file msgencode.c.
7663 - msg_parse to queryinfo/replyinfo conversion more versatile.
7664 - process_response, classify response, delegpt_from_message.
7667 - querytargets state.
7668 - dname_subdomain_c() routine.
7669 - server selection, based on RTT. ip6 is filtered out if not available,
7670 and lameness is checked too.
7671 - delegation point copy routine.
7674 - removed FLAG_CD from message and rrset caches. This was useful for
7675 an agnostic forwarder, but not for a sophisticated (trust value per
7676 rrset enabled) cache.
7677 - iterator response typing.
7678 - iterator cname handle.
7679 - iterator prime start.
7681 - processInitRequest and processInitRequest2.
7682 - cache synthesizes referral messages, with DS and NSEC.
7683 - processInitRequest3.
7684 - if a request creates multiple subrequests these are all activated.
7687 - routines to lock and unlock array of rrsets moved to cache/rrset.
7688 - lookup message from msg cache (and copy to region).
7689 - fixed cast error in dns msg lookup.
7690 - message with duplicate rrset does not increase its TTLs twice.
7691 - 'qnamesize' changed to 'qname_len' for similar naming scheme.
7694 - Acknowledge use of unbound-java code in iterator. Nicer readme.
7695 - services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
7696 rrset cache from module environment.
7697 - packed rrset key has type and class as easily accessible struct
7698 members. They are still kept in network format for fast msg encode.
7699 - dns cache find_delegation routine.
7700 - iterator main functions setup.
7701 - dns cache lookup setup.
7704 - small changes to prepare for subqueries.
7705 - iterator forwarder feature separated out.
7706 - iterator hints stub code, config file stub code, so that first
7707 testing can proceed locally.
7708 - replay tests now have config option to enable forwarding mode.
7711 - outside network does precise timers for roundtrip estimates for rtt
7712 and for setting timeout for UDP. Pending_udp takes milliseconds.
7713 - cleaner iterator sockaddr conversion of forwarder address.
7714 - iterator/iter_utils and iter_delegpt setup.
7718 - outbound query list for modules and support to callback with the
7719 outbound entry to the module.
7720 - testbound support for new serviced queries.
7721 - test for retry to TCP cannot use testbound any longer.
7722 - testns test for EDNS fallback, test for TCP fallback already exists.
7723 - fixes for no-locking compile.
7724 - mini_event timer precision and fix for change in timeouts during
7725 timeout callback. Fix for fwd_three tests, performed nonexit query.
7728 - small comment on hash table locking.
7729 - outside network serviced queries, contain edns and tcp fallback,
7730 and udp retries and rtt timing.

7756 - created release-0.3 svn tag.
7758 - fixed compression - no longer compresses root name.
7761 - outside network cleans up waiting tcp queries on exit.
7763 - testbound replay with retry in TCP mode.
7764 - tpkg test for retry in TCP mode, against ldns-testns server.

7766 - test where data expires in the cache.
7767 - compiletests: fixed empty body ifstatements in alloc.c, in case
7771 - outgoing network keeps list of available tcp buffers for outgoing
7773 - outgoing-num-tcp config option.
7774 - outgoing network keeps waiting list of queries waiting for buffer.

7812 But only for answers from other servers, not for plain queries.
7813 - compression and decompression test cases.
7815 - example.conf interface: line is changed from 127.0.0.1 which leads
7816 to problems if used (restricting communication to the localhost),

8039 so that they do not result in problems.
8040 - Also randomize the outgoing port range for tests.

8042 This makes all threads service incoming requests, instead of one.
8043 No memory is leaking during reloads, service of queries, etc.
8044 - test that uses ldns-testns -f to test threading. Have to answer
8045 three queries at the same time.
8046 - with verbose=0 operates quietly.

8056 23 February 2007: Wouter
8057 - Can do reloads on sigHUP. Everything is stopped, and freed,
8058 except the listening ports. Then the config file is reread.
8059 And everything is started again (and listening ports if needed).
8060 - Ports for queries are shared.
8061 - config file added interface:, chroot: and username:.
8062 - config file: directory, logfile, pidfile. And they work too.

8094 It is limited to 1024 file descriptors, and has less features.
8095 - will not create ip6 sockets if ip6 not on the machine.
8097 15 February 2007: Wouter
