294 load a readonly auto-trust-anchor-file with trust-anchor-file.
295 The file has to be writable to notice the trust anchor change,
296 without it, a trust anchor change will be unnoticed and the system
297 will then become inoperable.

357 comparisons (except if all responses are errors),
358 inability to find nameservers does not fail equality comparisons,
359 many nameservers does not try to compare more than max-sent-count,
360 parse failures start 0x20 fallback procedure.
361 - store caps_response with best response in case downgrade response
362 happens to be the last one.

627 Building with --enable-dnstap needs pkg-config with this patch.
628 - Noted dnstap in doc/README and doc/CREDITS.
629 - Changes to the dnstap patch.
631 - dnstap/dnstap_config.h should not have been added to the repo,
632 because is it generated.

636 from Maciej Soltysiak.
637 - iana portlist update.
640 - DNS64 from Viagenie (BSD Licensed), written by Simon Perrault.
641 Initial commit of the patch from the FreeBSD base (with its fixes).
642 This adds a module (for module-config in unbound.conf) dns64 that
643 performs DNS64 processing, see README.DNS64.
644 - Changes from DNS64:
645 strcpy changed to memmove.
646 arraybound check fixed from prefix_net/8/4 to prefix_net/8+4.
647 allocation of result consistently in the correct region.
648 time_t is now used for ttl in unbound (since the patch's version).
649 - testdata/dns64_lookup.rpl for unit test for dns64 functionality.
652 - Patch from Dag-Erling Smorgrav that implements feature, unbound -dd
653 does not fork in the background and also logs to stderr.
656 - Fix endian.h include for OpenBSD.

675 - update compat/getentropy and arc4random to the most recent ones from OpenBSD.
677 11 July 2014: Matthijs
678 - fake-rfc2553 patch (thanks Benjamin Baier).
681 - arc4random in compat/ and getentropy, explicit_bzero, chacha for
682 dependencies, from OpenBSD. arc4_lock and sha512 in compat.
683 This makes arc4random available on all platforms, except when
684 compiled with LIBNSS (it uses libNSS crypto random).
685 - fix strptime implicit declaration error on OpenBSD.
686 - arc4random, getentropy and explicit_bzero compat for Windows.
689 - Fix #593: segfault or crash upon rotating logfile.
693 - signit tool fixup for compile with libldns library.
694 - iana portlist updated.
697 - so-reuseport is available on BSDs(such as FreeBSD 10) and OS/X.
700 - unbound-control status reports if so-reuseport was successful.
701 - iana portlist updated.
704 - Fix caps-for-id fallback, and added fallback attempt when servers
705 drop 0x20 perturbed queries.

709 - iana portlist updated.
712 - Add AAAA for B root server to default root hints.
715 - Remove unused define from iterator.h
718 - Fixup sldns_enum_edns_option typedef definition.
721 - Code cleanup patch from Dag-Erling Smorgrav, with compiler issue
722 fixes from FreeBSD's copy of Unbound, he notes:
723 Generate unbound-control-setup.sh at build time so it respects
724 prefix and sysconfdir from the configure script. Also fix the
725 umask to match the comment, and the comment to match the umask.
726 Add const and static where needed. Use unions instead of
727 playing pointer poker. Move declarations that are needed in
728 multiple source files into a shared header. Move sldns_bgetc()
729 from parse.c to buffer.c where it belongs. Introduce a new
730 header file, worker.h, which declares the callbacks that
731 all workers must define. Remove those declarations from
732 libworker.h. Include the correct headers in the correct places.
733 Fix a few dummy callbacks that don't match their prototype.
734 Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK.
735 Remove a useless printf which breaks reproducible builds.
736 Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
737 no longer used. Add unbound-control-setup.sh to the list of
738 generated files. The prototype for libworker_event_done_cb()
739 needs to be moved from libunbound/libworker.h to
741 - Fixup out-of-directory compile with unbound-control-setup.sh.in.
745 - unbound-host -D enabled dnssec and reads root trust anchor from
746 the default root key file that was compiled in.
749 - Feature, unblock-lan-zones: yesno that you can use to make unbound
750 perform 10.0.0.0/8 and other reverse lookups normally, for use if
751 unbound is running service for localhost on localhost.
754 - Updated create_unbound_ad_servers and unbound_cache scripts from
755 Yuri Voinov in the source/contrib directory. Added
756 warmup.cmd (and .sh): warm up the DNS cache with your MRU domains.
759 - Implement draft-ietf-dnsop-rfc6598-rfc6303-01.
760 - iana portlist updated.
763 - Contrib windows scripts from Yuri Voinov added to src/contrib:
764 create_unbound_ad_servers.cmd: enters anti-ad server lists.
765 unbound_cache.cmd: saves and loads the cache.
766 - Added unbound-control-setup.cmd from Yuri Voinov to the windows
767 unbound distribution set. It requires openssl installed in %PATH%.
770 - Change MAX_SENT_COUNT from 16 to 32 to resolve some cases easier.
773 - More #567: remove : from output of stub and forward lists, this is
776 29 April 2014: Wouter
777 - iana portlist updated.
778 - Add unbound-control flush_negative that flushed nxdomains, nodata,
779 and errors from the cache. For dnssec-trigger and NetworkManager,
780 fixes cases where network changes have localdata that was already
781 negatively cached from the previous network.
783 23 April 2014: Wouter
784 - Patch from Jeremie Courreges-Anglas to use arc4random_uniform
785 if available on the OS, it gets entropy from the OS.
787 15 April 2014: Wouter
788 - Fix compile with libevent2 on FreeBSD.
790 11 April 2014: Wouter
791 - Fix #502: explain that do-ip6 disable does not stop AAAA lookups,

793 - iana portlist updated.
795 10 April 2014: Wouter
796 - iana portlist updated.
797 - Patch from Hannes Frederic Sowa for Linux 3.15 fragmentation
798 option for DNS fragmentation defense.

803 +i annotation in output of list_forwards, also for list_stubs
804 (for NetworkManager integration.)
805 - Fix #554: use unsigned long to print 64bit statistics counters on
807 - Fix #558: failed prefetch lookup does not remove cached response
808 but delays next prefetch (in lieu of caching a SERVFAIL).
809 - Fix #545: improved logging, the ip address of the error is printed
810 on the same log-line as the error.
813 - Fix #574: make test fails on Ubuntu 14.04. Disabled remote-control
814 in testbound scripts.
815 - iana portlist updated.
818 - C.ROOT-SERVERS.NET has an IPv6 address, and we updated the root
819 hints (patch from Anand Buddhdev).
820 - Fix #572: Fix unit test failure for systems with different
823 28 March 2014: Wouter
824 - Fix #569: do_tcp is do-tcp in unbound.conf man page.
826 25 March 2014: Wouter

840 27 February 2014: Wouter
843 21 February 2014: Wouter
844 - iana portlist updated.
846 20 February 2014: Matthijs
847 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
848 received. This is okay according 4035, but not after revising
849 existence in 4592. NSEC empty non-terminals exist and thus the
850 RCODE should have been NOERROR. If this occurs, and the RRsets
851 are secure, we set the RCODE to NOERROR and the security status
852 of the response is also considered secure.
854 14 February 2014: Wouter
855 - Works on Minix (3.2.1).
857 11 February 2014: Wouter

883 - fixup nss compile (no ldns in it).
884 - fixup warning in unitldns

886 are not portable; they cannot be read (for sure) on other computers.
887 - fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
890 30 January 2014: Wouter
891 - delay-close does not act if there are udp-wait queries, so that
892 it does not make a socketdrain DoS easier.
894 28 January 2014: Wouter
895 - iana portlist updated.
896 - iana portlist test updated so it does not touch the source
897 if there are no changes.
898 - delay-close: msec option that delays closing ports for which
899 the UDP reply has timed out. Keeps the port open, only accepts
900 the correct reply. This correct reply is not used, but the port
901 is open so that no port-denied ICMPs are generated.
903 27 January 2014: Wouter
904 - reuseport is attempted, then fallback to without on failure.
906 24 January 2014: Wouter
907 - Change unbound-event.h to use void* buffer, length idiom.
908 - iana portlist updated.
909 - unbound-event.h is installed if you configure --enable-event-api.
910 - speed up unbound (reports say it could be up to 10%), by reducing
911 lock contention on localzones.lock. It is changed to an rwlock.
912 - so-reuseport: yesno option to distribute queries evenly over
913 threads on Linux (Thanks Robert Edmonds).
916 21 January 2014: Wouter
917 - Fix #547: no trustanchor written if filesystem full, fclose checked.
919 17 January 2014: Wouter
920 - Fix isprint() portability in sldns, uses unsigned int.
921 - iana portlist updated.
923 16 January 2014: Wouter
924 - fix #544: Fixed +i causes segfault when running with module conf
926 - Windows port, adjust %lld to %I64d, and warning in win_event.c.
928 14 January 2014: Wouter
929 - iana portlist updated.
932 - Fix bug in cachedump that uses sldns.
933 - update pythonmod for ldns_ to sldns_ name change.
936 - Fix sldns to use sldns_ prefix for all ldns_ variables.
937 - Fix windows compile to compile with sldns.
940 - Fix sldns to make globals use sldns_ prefix. This fixes
941 linking with libldns that uses global variables ldns_ .
944 - Fix bug#537: compile python plugin without ldns library.
947 - Fix bug#536: acl_deny_non_local and refuse_non_local added.
950 - Patch from Neel Goyal to fix async id assignment if callback
951 is called by libunbound in the mesh attach.
952 - Accept ip-address: as an alternative for interface: for
953 consistency with nsd.conf syntax.
956 - Patch from Neel Goyal to fix callback in libunbound.
959 - if configured --with-libunbound-only fix make install.
962 - Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
963 more specific interface port 53 can be used at the same time, and
964 one of the daemons is unbound.
965 - iana portlist update.
966 - separate ldns into core ldns inside ldns/ subdirectory. No more
967 --with-ldns is needed and unbound does not rely on libldns.
968 - portability fixes for new USE_SLDNS ldns subdir codebase.
971 - Patch from Neel Goyal: Add an API call to set an event base on an
972 existing ub_ctx. This basically just destroys the current worker and
973 sets the event base to the current. And fix a deadlock in
974 ub_resolve_event – the cfglock is held when libworker_create is
975 called. This ends up trying to acquire the lock again in
976 context_obtain_alloc in the call chain.
977 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
980 - unbound-event.h is installed if configured --with-libevent. It
981 contains low-level library calls, that use libevent's event_base
982 and an ldns_buffer for the wire return packet to perform async
983 resolution in the client's eventloop.
986 - 1.4.21 tag created.
987 - trunk has 1.4.22 number inside it.

1004 - more fixes that I overlooked.
1005 - review fixes from Willem.

1017 - Fix uninit variable in fix#516.
1020 - Fix#516 dnssec lameness detection for answers that are improper.
1026 - Fix#512 memleak in testcode for testbound (if it fails).
1027 - Fix#512 NSS returned arrays out of setup function to be statics.

1045 - Fix for const string literals in C++ for libunbound, from Karel
1047 - iana portlist updated.
1050 - Fixup manpage syntax.
1053 - get_option and set_option support for log-time-ascii, python-script
1054 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
1055 immediately. The others are mostly useful for libunbound users.
1058 - get_option, set_option, unbound-checkconf -o and libunbound
1059 getoption and setoption support cache-min-ttl and cache-max-ttl.
1062 - Fix#501: forward-first does not recurse, when forward name is ".".
1063 - iana portlist update.
1064 - Max include depth is unlimited.
1067 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply
1068 patch to it to not fail when -Werror is also specified, from the
1070 - iana portlist update.
1073 - Explain bogus and secure flags in libunbound more.
1076 - Fix#499 use-after-free in out-of-memory handling code (thanks Jake
1078 - Fix#500 use on non-initialised values on socket bind failures.

1104 15 April 2013: Wouter
1105 - Fix so that for a configuration line of include: "*.conf" it is not
1106 an error if there are no files matching the glob pattern.

1304 serviced_query, without race conditions or administration issues.
1305 This should not happen with the current codebase, but it is robust.
1306 - Fix forward-first option where it sets the RD flag wrongly.
1307 - added manpage links for libunbound calls (Thanks Paul Wouters).
1309 30 July 2012: Wouter

1330 assertions in mesh.c resist duplicates. Fixes DS NS search to
1331 not generate duplicate sub queries.
1333 19 July 2012: Willem
1334 - Fix bug#454: Remove ACX_CHECK_COMPILER_FLAG from configure.ac,
1335 if CFLAGS is specified at configure time then '-g -O2' is not
1336 appended to CFLAGS, so that the user can override them.

1491 23 February 2012: Wouter
1492 - Fix to squelch 'network unreachable' errors from tcp connect in
1493 logs, high verbosity will show them.
1495 16 February 2012: Wouter
1496 - iter_hints is now thread-owned in module env, and thus threadsafe.
1497 - Fix prefetch and sticky NS, now the prefetch works. It picks
1498 nameservers that 'would be valid in the future', and if this makes
1499 the NS timeout, it updates that NS by asking delegation from the
1500 parent again. If child NS has longer TTL, that TTL does not get
1501 refreshed from the lookup to the child nameserver.
1503 15 February 2012: Wouter
1504 - Fix forward-zone memory, uses malloc and frees original root dp.
1505 - iter hints (stubs) uses malloc inside for more dynamicity.
1506 - unbound-control forward_add, forward_remove, stub_add, stub_remove
1507 can modify stubs and forwards for running unbound (on mobile computer)

1527 8 February 2012: Wouter
1528 - implement draft-ietf-dnsext-ecdsa-04; which is in IETF LC; This
1529 implementation is experimental at this time and not recommended
1530 for use on the public internet (the protocol numbers have not
1531 been assigned). Needs recent ldns with --enable-ecdsa.
1532 - fix memory leak in errorcase for DSA signatures.
1533 - iana portlist updated.
1534 - workaround for openssl 0.9.8 ecdsa sha2 and evp problem.

1546 closest encloser from yy for DS zz. while building chain of trust,
1547 because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
1548 for an NSEC3. Now it does not change rdata, and fixes TTL.
1550 30 January 2012: Wouter
1551 - Fix version-number in libtool to be version-info so it produces
1552 libunbound.so.2 like it should.
1554 26 January 2012: Wouter

1566 19 January 2012: Wouter
1567 - Fix to write key files completely to a temporary file, and if that

1570 18 January 2012: Wouter
1571 - tag 1.4.15rc1 created
1572 - updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
1574 17 January 2012: Wouter
1575 - Fix bug where canonical_compare of RRSIG did not downcase the
1576 signer-name. This is mostly harmless because RRSIGs do not have
1577 to be sorted in canonical order, usually.
1579 12 January 2012: Wouter
1580 - bug#428: add ub_version() call to libunbound. API version increase,
1581 with (binary) backwards compatibility for the previous version.
1583 10 January 2012: Wouter
1584 - Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
1585 that would be permissible by the RFCs but it is not the TTL in the

1595 24 December 2011: Wouter
1596 - Fix for memory leak (about 20 bytes when a tcp or udp send operation
1597 towards authority servers failed, takes about 50.000 such failures to
1598 leak one Mb, such failures are also usually logged), reported by
1600 - iana portlist updated.
1602 19 December 2011: Wouter
1603 - Fix for VU#209659 CVE-2011-4528: Unbound denial of service
1604 vulnerabilities from nonstandard redirection and denial of existence
1605 http://www.unbound.net/downloads/CVE-2011-4528.txt

1658 - iana portlist updated.
1659 - fix -flto detection on Lion for llvm-gcc.
1661 31 October 2011: Wouter
1662 - dns over ssl support, ssl-service-pem and ssl-service-key files
1663 can be given and then TCP queries are serviced wrapped in SSL.
1665 27 October 2011: Wouter
1666 - lame-ttl and lame-size options no longer exist, it is integrated
1667 with the host info. They are ignored (with verbose warning) if
1668 encountered to keep the config file backwards compatible.
1669 - fix iana-update for changing gzip compression of results.
1670 - fix export-all-symbols on OSX.
1672 26 October 2011: Wouter

1675 This fixes bug #416.
1676 - fix iana_update target for gzipped file on iana site.
1678 24 October 2011: Wouter
1679 - Fix resolve of partners.extranet.microsoft.com with a fix for the
1680 server selection for choosing out of a (particular) list of bad
1682 - Fix make_new_space function so that the incoming query is not
1683 overwritten if a jostled out query causes a waiting query to be
1684 resumed that then fails and sends an error message. (Thanks to
1687 21 October 2011: Wouter
1688 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
1689 option enabled because of memory layout exe vs dll.
1691 19 October 2011: Wouter
1692 - fix unbound-anchor for broken strptime on OSX lion, detected

1701 - Fix for out-of-memory condition in libunbound (thanks
1704 13 October 2011: Wouter
1705 - Fix --enable-allsymbols, it depended on link specifics of the
1706 target platform, or fptr_wlist assertion failures could occur.
1708 12 October 2011: Wouter
1709 - updated contrib/unbound_munin_ to family=auto so that it works with
1710 munin-node-configure automatically (if installed as
1711 /usr/local/share/munin/plugins/unbound_munin_ ).
1713 27 September 2011: Wouter
1714 - unbound.exe -w windows option for start and stop service.

1720 20 September 2011: Wouter
1721 - Fix classification of NS set in answer section, where there is a

1723 Thanks to Amanda Constant from Secure64.
1725 16 September 2011: Wouter
1726 - fix bug #408: accept patch from Steve Snyder that comments out
1727 unused functions in lookup3.c.
1728 - iana portlist updated.
1729 - fix EDNS1480 change memleak and TCP fallback.
1730 - fix various compiler warnings (reported by Paul Wouters).
1731 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
1732 fetch if sentcount > 3, stop query if sentcount > 16. Count is
1733 reset when referral or CNAME happens. This makes unbound better
1734 at managing large NS sets, they are explored when there is continued
1735 interest (in the form of queries).
1737 15 September 2011: Wouter
1739 - trunk contains 1.4.14 in development.
1740 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
1742 12 September 2011: Wouter
1743 - Reverted dns EDNS backoff fix, it did not help and needs
1744 fragmentation fixes instead.
1747 7 September 2011: Wouter
1748 - Fix operation in ipv6 only (do-ip4: no) mode.
1750 6 September 2011: Wouter
1751 - fedora specfile updated.

1756 2 September 2011: Wouter
1757 - iana portlist updated.
1759 26 August 2011: Wouter
1760 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
1761 - Fix validation failures due to EDNS backoff retries, the retry
1762 for fetch of data has want_dnssec because the iter_indicate_dnssec
1763 function returns true when validation failure retry happens, and
1764 then the serviced query code does not fallback to noEDNS, even if
1765 the cache says it has this. This helps for DLV deployment when
1766 the DNSSEC status is not known for sure before the lookup concludes.
1768 24 August 2011: Wouter
1769 - Applied patch from Karel Slany that fixes a memory leak in the
1770 unbound python module, in string conversions.
1772 22 August 2011: Wouter
1773 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
1774 Zhang and Luo Ce). Unbound responds with the RR types that are
1775 available at the name for qtype ANY and validates those RR types.
1776 It does not test for completeness (i.e. with NSEC or NSEC3 query),
1777 and it does not follow the CNAME or DNAME to another name (with
1778 even more data for the already large response).
1779 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
1780 - Documented the options that work with control set_option command.
1781 - tcp-upstream yes/no option (works with set_option) for tunnels.
1783 18 August 2011: Wouter
1784 - fix autoconf call in makedist crosscompile to RC or snapshot.
1786 17 August 2011: Wouter

1822 - version number in example config file.
1823 - fix that --enable-static-exe does not complain about it unknown.
1825 30 June 2011: Wouter
1826 - tag relase 1.4.11, trunk is 1.4.12 development.
1827 - iana portlist updated.
1828 - fix bug#395: id bits of other query may leak out under conditions
1829 - fix replyaddr count wrong after jostled queries, which leads to
1830 eventual starvation where the daemon has no replyaddrs left to use.
1831 - fix comment about rndc port, that referred to the old port number.
1832 - fix that the listening socket is not closed when too many remote
1833 control connections are made at the same time.
1834 - removed ldns-src tarball inside the unbound tarball.
1836 23 June 2011: Wouter
1837 - Changed -flto check to support clang compiler.
1838 - tag 1.4.11rc3 created.
1840 17 June 2011: Wouter
1841 - tag 1.4.11rc1 created.
1842 - remove warning about signed/unsigned from flex (other flex version).
1843 - updated aclocal.m4 and libtool to match.
1844 - tag 1.4.11rc2 created.
1846 16 June 2011: Wouter
1847 - log-queries: yesno option, default is no, prints querylog.
1848 - version is 1.4.11.
1850 14 June 2011: Wouter
1851 - Use -flto compiler flag for link time optimization, if supported.
1852 - iana portlist updated.
1854 12 June 2011: Wouter
1855 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
1857 10 June 2011: Wouter
1858 - unbound-control has version number in the header,
1859 UBCT[version]_space_ is the header sent by the client now.
1860 - Unbound control port number is registered with IANA:
1861 ub-dns-control 8953/tcp unbound dns nameserver control
1862 This is the new default for the control-port config setting.
1863 - statistics-interval prints the number of jostled queries to log.
1866 - Fix Makefile for U in environment, since wrong U is more common than
1867 deansification necessity.
1868 - iana portlist updated.
1869 - updated ldns tarball to 1.6.10rc2 snapshot of today.
1872 - Fix assertion failure when unbound generates an empty error reply
1873 in response to a query, CVE-2011-1922 VU#531342.
1874 - This fix is in tag 1.4.10.
1875 - defense in depth against the above bug, an error is printed to log
1876 instead of an assertion failure.
1879 - bug#386: --enable-allsymbols option links all binaries to libunbound
1880 and reduces install size significantly.
1881 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
1882 - iana portlist updated.
1883 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
1885 14 April 2011: Wouter
1886 - configure created with newer autoconf 2.66.
1888 12 April 2011: Wouter
1889 - bug#378: Fix that configure checks for ldns_get_random presence.
1891 8 April 2011: Wouter
1892 - iana portlist updated.
1893 - queries with CD flag set cause DNSSEC validation, but the answer is
1894 not withheld if it is bogus. Thus, unbound will retry if it is bad
1895 and curb the TTL if it is bad, thus protecting the cache for use by
1896 downstream validators.
1897 - val-override-date: -1 ignores dates entirely, for NTP usage.
1899 29 March 2011: Wouter
1900 - harden-below-nxdomain: changed so that it activates when the
1901 cached nxdomain is dnssec secure. This avoids backwards
1902 incompatibility because those old servers do not have dnssec.
1904 24 March 2011: Wouter
1905 - iana portlist updated.
1909 17 March 2011: Wouter
1910 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
1911 Applied but did not do the --disable-gost.

1921 - give config parse error for multiple names on a stub or forward zone.
1922 - updated ldns tarball to 1.6.9(todays snapshot).

1936 Please note usage of unbound-anchor root anchor is at your own risk
1937 and under the terms of our LICENSE (see that file in the source).
1939 11 February 2011: Wouter
1940 - iana portlist updated.
1941 - tpkg updated with common.sh for common functionality.
1943 7 February 2011: Wouter
1944 - Added regression test for addition of a .net DS to the root, and
1945 cache effects with different TTL for glue and DNSKEY.

1961 17 January 2011: Wouter
1962 - add get and set option for harden-below-nxdomain feature.
1963 - iana portlist updated.
1965 14 January 2011: Wouter
1966 - Fix so a changed NS RRset does not get moved name stuck on old
1967 server, for type NS the TTL is not increased.
1969 13 January 2011: Wouter
1970 - Fix prefetch so it does not get stuck on old server for moved names.
1972 12 January 2011: Wouter
1973 - iana portlist updated.
1975 11 January 2011: Wouter
1976 - Fix insecure CNAME sequence marked as secure, reported by Bert

1984 - iana portlist updated.
1986 23 December 2010: Wouter
1987 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
1989 21 December 2010: Wouter
1990 - algorithm compromise protection using the algorithms signalled in
1991 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
1992 and thus, if you have multiple algorithms in your trust-anchor-file
1993 then it will now behave different than before. Also, 5011 rollover
1994 for algorithms needs to be double-signature until the old algorithm
1996 It is not an option, because I see no use to turn the security off.
1997 - iana portlist updated.
1999 17 December 2010: Wouter
2000 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
2001 - fix validation in this case: CNAME to nodata for co-hosted opt-in
2002 NSEC3 insecure delegation, was bogus, fixed to be insecure.

2019 - iana portlist updated.
2021 18 November 2010: Wouter
2022 - harden-below-nxdomain option, default off (because very old
2023 software may be incompatible). We could enable it by default in
2026 17 November 2010: Wouter
2027 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
2028 - make test output nicer.
2030 15 November 2010: Wouter
2031 - silence 'tcp connect: broken pipe' and 'net down' at low verbosity.

2052 2 November 2010: Wouter
2056 1 November 2010: Wouter
2057 - GOST code enabled by default (RFC 5933).
2059 27 October 2010: Wouter
2060 - Fix uninit value in dump_infra print.
2061 - Fix validation failure for parent and child on same server with an
2062 insecure childzone and a CNAME from parent to child.
2063 - Configure detects libev-4.00.
2065 26 October 2010: Wouter
2066 - dump_infra and flush_infra commands for unbound-control.
2067 - no timeout backoff if meanwhile a query succeeded.
2068 - Change of timeout code. No more lost and backoff in blockage.
2069 At 12sec timeout (and at least 2x lost before) one probe per IP
2070 is allowed only. At 120sec, the IP is blocked. After 15min, a
2071 120sec entry has a single retry packet.
2073 25 October 2010: Wouter
2074 - Configure errors if ldns is not found.
2076 22 October 2010: Wouter
2077 - Windows 7 fix for the installer.
2079 21 October 2010: Wouter
2080 - Fix bug where fallback_tcp causes wrong roundtrip and edns
2081 observation to be noted in cache. Fix bug where EDNSprobe halted
2082 exponential backoff if EDNS status unknown.
2083 - new unresponsive host method, exponentially increasing block backoff.
2084 - iana portlist updated.
2086 20 October 2010: Wouter
2087 - interface automatic works for some people with ip6 disabled.
2088 Therefore the error check is removed, so they can use the option.
2090 19 October 2010: Wouter
2091 - Fix for request list growth, if a server has long timeout but the
2092 lost counter is low, then its effective rtt is the one without
2093 exponential backoff applied. Because the backoff is not working.
2094 The lost counter can then increase and the server is blacklisted,
2095 or the lost counter does not increase and the server is working
2098 18 October 2010: Wouter
2099 - iana portlist updated.
2101 13 October 2010: Wouter
2102 - Fix TCP so it uses a random outgoing-interface.
2103 - unbound-anchor handles ADDPEND keystate.
2105 11 October 2010: Wouter
2106 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
2107 the zone has a secure delegation hosted on the same server did not
2108 verify as secure (it was insecure by mistake).
2109 - iana portlist updated.
2110 - ldns tarball updated (for reading cachedumps with bad RR data).
2112 1 October 2010: Wouter

2114 - Fix alloc_reg_release for longer uptime in out of memory conditions.
2116 28 September 2010: Wouter
2117 - unbound-anchor working, it creates or updates a root.key file.

2121 - iana portlist updated.
2123 24 September 2010: Wouter

2126 23 September 2010: Wouter
2127 - unbound-anchor app, unbound requires libexpat (xml parser library).
2129 22 September 2010: Wouter
2130 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
2131 reverse ipv6 orchid prefix from builtin list.
2132 - iana portlist updated.
2134 17 September 2010: Wouter
2135 - DLV has downgrade protection again, because the RFC says so.
2136 - iana portlist updated.
2138 16 September 2010: Wouter
2139 - Algorithm rollover operational reality intrudes, for trust-anchor,
2140 5011-store, and DLV-anchor if one key matches it's good enough.
2141 - iana portlist updated.
2142 - Fix reported validation error in out of memory condition.
2144 15 September 2010: Wouter
2145 - Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
2147 14 September 2010: Wouter
2148 - increased mesh-max-activation from 1000 to 3000 for crazy domains
2149 like _tcp.slb.com with 262 servers.
2150 - iana portlist updated.
2152 13 September 2010: Wouter
2153 - bug#327: Fix for cannot access stub zones until the root is primed.
2155 9 September 2010: Wouter
2156 - unresponsive servers are not completely blacklisted (because of
2157 firewalls), but also not probed all the time (because of the request
2158 list size it generates). The probe rate is 1%.
2159 - iana portlist updated.
2161 20 August 2010: Wouter
2162 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
2163 iterator get_mem includes priv_get_mem. delegpt nodup removed.
2164 listen_pushback, query_info_allocqname, write_socket, send_packet,
2165 comm_point_set_cb_arg and listen_resume removed.
2167 19 August 2010: Wouter
2168 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
2169 Delegpt structures checked for duplicates always.
2170 No more nameserver lookups generated when depth is full anyway.
2171 - example.conf notes how to do DNSSEC validation and track the root.
2172 - iana portlist updated.
2174 18 August 2010: Wouter
2175 - Fix bug#322: configure does not respect CFLAGS on Solaris.
2176 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
2177 if use sun-cc, but some systems need different flags.
2179 16 August 2010: Wouter
2180 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
2181 changes, uses m4_bpatsubst now.
2182 - make test (or make check) should be more portable and run the unit
2183 test and testbound scripts. (make longtest has special requirements).
2185 13 August 2010: Wouter
2186 - More pleasant remote control command parsing.
2187 - documentation added for return values reported by doxygen 1.7.1.
2188 - iana portlist updated.
2190 9 August 2010: Wouter
2191 - Fix name of rrset printed that failed validation.
2193 5 August 2010: Wouter
2194 - Return NXDOMAIN after chain of CNAMEs ends at name-not-found.
2196 4 August 2010: Wouter
2197 - Fix validation in case a trust anchor enters into a zone with
2198 unsupported algorithms.
2200 3 August 2010: Wouter

2210 - rlimit adjustments for select and ulimit can happen at the same time.
2212 14 July 2010: Wouter
2213 - Donation text added to README.
2214 - Fix integer underflow in prefetch ttl creation from cache. This
2215 fixes a potential negative prefetch ttl.
2217 12 July 2010: Wouter
2218 - Changed the defaults for num-queries-per-thread/outgoing-range.
2219 For builtin-select: 512/960, for libevent 1024/4096 and for
2220 windows 24/48 (because of win api). This makes the ratio this way
2221 to improve resilience under heavy load. For high performance, use
2222 libevent and possibly higher numbers.
2224 10 July 2010: Wouter
2225 - GOST enabled if SSL is recent and ldns has GOST enabled too.
2226 - ldns tarball updated.
2229 - iana portlist updated.
2230 - Fix validation of qtype DNSKEY when a key-cache entry exists but
2231 no rr-cache entry is used (it expired or prefetch), it then goes
2232 back up to the DS or trust-anchor to validate the DNSKEY.
2235 - Neat function prototypes, unshadowed local declarations.
2238 - failure to chown the pidfile is not fatal any more.
2239 - testbound uses UTC timezone.
2240 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
2241 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
2244 - log if a server is skipped because it is on the donotquery list,
2245 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
2246 - added feature to print configure date, target and options with -h.
2247 - added feature to print event backend system details with -h.
2248 - wdiff is not actually required by make test, updated requirements.
2251 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
2252 must be signed with all algorithms from the DS rrset at the parent.
2253 This is now checked and becomes bogus if not.
2255 28 June 2010: Wouter
2256 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
2257 in overload situations to be about 5 qps for the class of shortly
2259 The capacity of the resolver is then about (numqueriesperthread / 2)
2260 / (average time for such long queries) qps for long queries.
2261 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
2262 qps for short queries, per thread.
2263 - Fix the max number of reply-address count to be applied for duplicate
2264 queries, and not for new query list entries. This raises the memory
2265 usage to a max of (16+1)*numqueriesperthread reply addresses.
2267 25 June 2010: Wouter
2268 - Fix handling of corner case reply from lame server, follows rfc2308.
2269 It could lead to a nodata reply getting into the cache if the search
2270 for a non-lame server turned up other misconfigured servers.
2271 - unbound.h has extern "C" statement for easier include in c++.
2273 23 June 2010: Wouter
2274 - iana portlist updated.
2275 - makedist upgraded cross compile openssl option, like this:
2276 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
2278 22 June 2010: Wouter
2279 - Unbound reports libev or libevent correctly in logs in verbose mode.
2280 - Fix to unload gost dynamic library module for leak testing.
2282 18 June 2010: Wouter
2283 - iana portlist updated.
2285 17 June 2010: Wouter
2286 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
2288 16 June 2010: Wouter
2289 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
2290 assertion was wrong.
2291 - updated ldns tarball.
2293 15 June 2010: Wouter
2294 - tag 1.4.5 created.
2295 - trunk contains 1.4.6 in development.
2296 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
2297 - Fix to use one pointer less for iterator query state store_parent_NS.
2298 - makedist crosscompile to windows uses builtin ldns not host ldns.
2299 - Max referral count from 30 to 130, because 128 one character domains
2301 - added documentation for the histogram printout to syslog.
2303 11 June 2010: Wouter
2304 - When retry to parent the retrycount is not wiped, so failed
2305 nameservers are not tried again.
2306 - iana portlist updated.
2308 10 June 2010: Wouter
2309 - Fix bug where a long loop could be entered, now cycle detection
2310 has a loop-counter and maximum search amount.
2313 - iana portlist updated.
2314 - 1.4.5rc1 tag created.
2317 - ldns tarball updated, 1.6.5.
2318 - review comments, split dependency cycle tracking for parentside
2319 last resort lookups for A and AAAA so there are more lookup options.
2322 - Fix compile warning if compiled without threads.
2323 - updated ldns-tarball with current ldns svn (pre 1.6.5).
2324 - GOST disabled-by-default, the algorithm number is allocated but the
2325 RFC is still has to pass AUTH48 at the IETF.
2328 - Ignore Z flag in incoming messages too.
2329 - Fix storage of negative parent glue if that last resort fails.
2330 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
2331 - new splint flags for newer splint install.
2334 - Fix AD flag handling, it could in some cases mistakenly copy the AD
2335 flag from upstream servers.
2336 - alloc_special_obtain out of memory is not a fatal error any more,
2337 enabling unbound to continue longer in out of memory conditions.
2338 - parentside names are dispreferred but not said to be dnssec-lame.
2339 - parentside check for cached newname glue.
2340 - fix parentside and querytargets modulestate, for dump_requestlist.
2341 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
2342 - fix parentside from cache to be marked dispreferred for bad names.
2345 - iana portlist updated.
2346 - parent-child disagreement approach altered. Older fixes are
2347 removed in place of a more exhaustive search for misconfigured data
2348 available via the parent of a delegation.
2349 This is designed to be throttled by cache entries, with TTL from the
2350 parent if possible. Additionally the loop-counter is used.
2351 It also tests for NS RRset differences between parent and child.
2352 The fetch of misconfigured data should be more reliable and thorough.
2353 It should work reliably even with no or only partial data in cache.
2354 Data received from the child (as always) is deemed more
2355 authoritative than information received from the delegation parent.
2356 The search for misconfigured data is not performed normally.
2359 - Contribution from Migiel de Vos (Surfnet): nagios patch for
2360 unbound-host, in contrib/ (in the source tarball). Makes
2361 unbound-host suitable for monitoring dnssec(-chain) status.
2364 - EDNS timeout code will not fire if EDNS status already known.
2365 - EDNS failure not stored if EDNS status known to work.
2368 - Fix resolution for domains like safesvc.com.cn. If the iterator
2369 can not recurse further and it finds the delegation in a state
2370 where it would otherwise have rejected it outhand if so received
2371 from a cache lookup, then it can try to ask higherup (with loop
2373 - Fix comments in iter_utils:dp_is_useless.
2376 - Fix various compiler warnings from the clang llvm compiler.
2377 - iana portlist updated.
2380 - Fix bug#308: spelling error in variable name in parser and lexer.
2383 - Fix dnssec-missing detection that was turned off by server selection.
2384 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
2385 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
2386 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
2388 29 April 2010: Wouter
2389 - Fix for dnssec lameness detection to use the key cache.
2390 - infra cache entries that are expired are wiped clean. Previously
2391 it was possible to not expire host data (if accessed often).
2393 28 April 2010: Wouter
2394 - ldns tarball updated and GOST support is detected and then enabled.
2395 - iana portlist updated.
2396 - Fix detection of gost support in ldns (reported by Chris Smith).
2398 27 April 2010: Wouter
2399 - unbound-control get_option domain-insecure shows config file items.
2400 - fix retry sequence if prime hints are recursion-lame.
2401 - autotrust anchor file can be initialized with a ZSK key as well.
2402 - harden-referral-path does not result in failures due to max-depth.
2403 You can increase the max-depth by adding numbers (' 0') after the
2404 target-fetch-policy, this increases the depth to which is checked.
2406 26 April 2010: Wouter
2407 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
2408 CPPFLAGS during configure process.
2409 - if libev is installed on the base system (not libevent), detect
2410 it from the event.h header file and link with -lev.
2411 - configlexer.lex gets config.h, and configyyrename.h added by make,
2412 no more double include.
2413 - More strict scrubber (Thanks to George Barwood for the idea):
2414 NS set must be pertinent to the query (qname subdomain nsname).
2415 - Fix bug#307: In 0x20 backoff fix fallback so the number of
2416 outstanding queries does not become -1 and block the request.
2417 Fixed handling of recursion-lame in combination with 0x20 fallback.
2418 Fix so RRsets are compared canonicalized and sorted if the immediate
2419 comparison fails, this makes it work around round-robin sites.
2421 23 April 2010: Wouter
2422 - Squelch log message: sendto failed permission denied for
2423 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
2424 - Fix to fetch data as last resort more tenaciously. When cycle
2425 targets cause the server selection to believe there are more options
2426 when they really are not there, the server selection is reinitiated.
2427 - Fix fetch from blacklisted dnssec lame servers as last resort. The
2428 server's IP address is then given in validator errors as well.
2429 - Fix local-zone type redirect that did not use the query name for
2432 22 April 2010: Wouter
2434 - trunk contains 1.4.5 in development.
2435 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
2436 The validator error message was 'no signatures from ...'.
2438 16 April 2010: Wouter
2439 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
2442 15 April 2010: Wouter
2443 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
2444 example key and signatures for GOST. GOST requires openssl-1.0.0.
2445 GOST is still disabled by default.
2447 9 April 2010: Wouter
2448 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
2449 get into an endless loop, if 0x20 was enabled, and buffers are small
2450 or particular broken packets are received.
2451 - Fix chain of trust with CNAME at an intermediate step, for the DS
2454 8 April 2010: Wouter
2455 - Fix validation of queries with wildcard names (*.example).
2457 6 April 2010: Wouter
2458 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
2459 cache timeout coincided with a server update, the current EDNS
2460 backoff is less sensitive, and does not cache the backoff unless
2461 the backoff actually works and the domain is not expecting DNSSEC.
2462 - GOST support with correct algorithm numbers.
2464 1 April 2010: Wouter
2465 - iana portlist updated.
2467 24 March 2010: Wouter
2468 - unbound control flushed items are not counted when flushed again.
2470 23 March 2010: Wouter
2471 - iana portlist updated.
2473 22 March 2010: Wouter
2474 - unbound-host disables use-syslog from config file so that the
2475 config file for the main server can be used more easily.
2476 - fix bug#301: unbound-checkconf could not parse interface
2477 '0.0.0.0@5353', even though unbound itself worked fine.
2479 19 March 2010: Wouter
2480 - fix fwd_ancil test to pass if the socket options are not supported.
2482 18 March 2010: Wouter
2483 - Fixed random numbers for port, interface and server selection.
2484 Removed very small bias.
2485 - Refer to the listing in unbound-control man page in the extended
2486 statistics entry in the unbound.conf man page.
2488 16 March 2010: Wouter
2489 - Fix interface-automatic for OpenBSD: msg.controllen was too small,
2490 also assertions on ancillary data buffer.
2491 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
2492 - for NSEC3 check if signatures are cached.
2494 15 March 2010: Wouter
2495 - unit test for util/regional.c.
2497 12 March 2010: Wouter
2498 - Reordered configure checks so fork and -lnsl -lsocket checks are
2499 earlier, and thus later checks benefit from and do not hinder them.
2500 - iana portlist updated.
2501 - ldns tarball updated.
2502 - Fix python use when multithreaded.
2503 - Fix solaris python compile.
2504 - Include less in config.h and include per code file for ldns, ssl.
2506 11 March 2010: Wouter
2507 - another memory allocation option: --enable-alloc-nonregional.
2508 exposes the regional allocations to other memory purifiers.
2509 - fix for memory alignment in struct sock_list allocation.
2510 - Fix for MacPorts ldns without ssl default, unbound checks if ldns
2511 has dnssec functionality and uses the builtin if not.
2512 - Fix daemonize on Solaris 10, it did not detach from terminal.
2513 - tag 1.4.3 created.
2514 - trunk is 1.4.4 in development.
2515 - spelling fix in validation error involving cnames.
2517 10 March 2010: Wouter
2518 - --enable-alloc-lite works with test set.
2519 - portability in the testset: printf format conversions, prototypes.
2521 9 March 2010: Wouter
2522 - tag 1.4.2 created.
2523 - trunk is 1.4.3 in development.
2524 - --enable-alloc-lite debug option.
2526 8 March 2010: Wouter
2527 - iana portlist updated.
2529 4 March 2010: Wouter
2530 - Fix crash in control channel code.
2532 3 March 2010: Wouter
2533 - better casts in pipe code, brackets placed wrongly.
2534 - iana portlist updated.
2536 1 March 2010: Wouter
2537 - make install depends on make all.
2538 - Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
2539 - --enable-checking: enables assertions but does not look nonproduction.
2540 - nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
2541 nxdomain and nodata distinguished.
2542 - ldns tarball updated.
2543 - --disable-rpath fixed for libtool not found errors.
2544 - new fedora specfile from Fedora13 in contrib from Paul Wouters.
2546 26 February 2010: Wouter
2547 - Fixup prototype for lexer cleanup in daemon code.
2548 - unbound-control list_stubs, list_forwards, list_local_zones and
2551 24 February 2010: Wouter
2552 - Fix scrubber bug that potentially let NS records through. Reported
2554 - Also delete potential poison references from additional.
2555 - Fix: no classification of a forwarder as lame, throw away instead.
2557 23 February 2010: Wouter
2558 - libunbound ub_ctx_get_option() added.
2559 - unbound-control set_option and get_option commands.
2560 - iana portlist updated.
2562 18 February 2010: Wouter
2563 - A little more strict DS scrubbing.
2564 - No more blacklisting of unresponsive servers, a 2 minute timeout
2566 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.
2567 - pickup ldns compile fix, libdl for libcrypto.
2568 - log 'tcp connect: connection timed out' only in high verbosity.
2569 - unbound-control log_reopen command.
2570 - moved get_option code from unbound-checkconf to util/config_file.c
2572 17 February 2010: Wouter
2573 - Disregard DNSKEY from authority section for chain of trust.
2574 DS records that are irrelevant to a referral scrubbed. Anti-poison.
2575 - iana portlist updated.
2577 16 February 2010: Wouter
2578 - Check for 'no space left on device' (or other errors) when
2579 writing updated autotrust anchors and print errno to log.
2581 15 February 2010: Wouter
2582 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
2583 hardcoded. We made the choice to send out more conservatively,
2584 protecting against an aggregate effect more than protecting a
2585 single user (from their own folly, perhaps in case of misconfig).
2587 12 February 2010: Wouter
2588 - Re-query pattern changed on validation failure. To protect troubled
2589 authority servers, unbound caches a failure for the DNSKEY or DS
2590 records for the entire zone, and only retries that 900 seconds later.
2591 This implies that only a handful of packets are sent extra to the
2592 authority if the zone fails.
2594 11 February 2010: Wouter
2595 - ldns tarball update for long label length syntax error fix.
2596 - iana portlist updated.
2598 9 February 2010: Wouter
2599 - Fixup in compat snprintf routine, %f 1.02 and %g support.
2600 - include math.h for testbound test compile portability.
2602 2 February 2010: Wouter
2603 - Updated url of IANA itar, interim trust anchor repository, in script.
2605 1 February 2010: Wouter
2606 - iana portlist updated.
2607 - configure test for memcmp portability.
2609 27 January 2010: Wouter
2610 - removed warning on format string in validator error log statement.
2611 - iana portlist updated.
2613 22 January 2010: Wouter
2614 - libtool finish the install of unbound python dynamic library.
2616 21 January 2010: Wouter
2617 - acx_nlnetlabs.m4 synchronised with nsd's version.
2619 20 January 2010: Wouter
2620 - Fixup lookup trouble for parent-child domains on the first query.
2622 14 January 2010: Wouter
2623 - Fixup ldns detection to also check for header files.
2625 13 January 2010: Wouter
2626 - prefetch-key option that performs DNSKEY queries earlier in the
2627 validation process, and that could halve the latency on DNSSEC
2628 queries. It takes some extra processing (CPU, a cache is needed).
2630 12 January 2010: Wouter
2631 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
2633 8 January 2010: Wouter
2634 - Fix for parent-child disagreement code which could have trouble
2635 when (a) ipv6 was disabled and (b) the TTL for parent and child
2636 were different. There were two bugs, the parent-side information
2637 is fixed to no longer block lookup of child side information and
2638 the iterator is fixed to no longer attempt to get ipv6 when it is
2639 not enabled and then give up in failure.
2640 - test and fixes to make prefetch actually store the answer in the
2641 cache. Considers some rrsets 'already expired' but does not allow
2642 overwriting of rrsets considered more secure.
2644 7 January 2010: Wouter
2645 - Fixup python documentation (thanks Leo Vandewoestijne).
2646 - Work on cache prefetch feature.
2647 - Stats for prefetch, in log print stats, unbound-control stats
2648 and in unbound_munin plugin.
2650 6 January 2010: Wouter
2651 - iana portlist updated.
2652 - bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.
2653 - verbose output includes parent-side-address notion for lameness.
2654 - documented val-log-level: 2 setting in example.conf and man page.
2655 - change unbound-control-setup from 1024(sha1) to 1536(sha256).
2657 1 January 2010: Wouter
2658 - iana portlist updated.
2660 22 December 2009: Wouter
2661 - configure with newer libtool 2.2.6b.
2663 17 December 2009: Wouter
2666 - trunk to version 1.4.2.
2668 15 December 2009: Wouter
2669 - Answer to qclass=ANY queries, with class IN contents.
2670 Test that validation also works.
2671 - updated ldns snapshot tarball with latest fixes (parsing records).
2673 11 December 2009: Wouter
2674 - on IPv4 UDP turn off DF flag.
2676 10 December 2009: Wouter
2677 - requirements.txt updated with design choice explanations.
2678 - Reading fixes: fix to set unlame when child confirms parent glue,
2679 and fix to avoid duplicate addresses in delegation point.
2680 - verify_rrsig routine checks expiration last.
2682 9 December 2009: Wouter
2683 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
2684 errors generated for domain names like '.example.com'.
2685 - Fix SOA excluded from negative DS responses. Reported by Hauke
2686 Lampe. The negative cache did not include proper SOA records for
2687 negative qtype DS responses which makes BIND barf on it, such
2688 responses are now only used internally.
2689 - Fix negative cache lookup of closestencloser check of DS type bit.
2691 8 December 2009: Wouter
2692 - Fix for lookup of parent-child disagreement domains, where the
2693 parent-side glue works but it does not provide proper NS, A or AAAA
2694 for itself, fixing domains such as motorcaravanners.eu.
2695 - Feature: you can specify a port number in the interface: line, so
2696 you can bind the same interface multiple times at different ports.
2698 7 December 2009: Wouter
2699 - Bug#287: Fix segfault when unbound-control remove nonexistent local
2700 data. Added check to tests.
2702 1 December 2009: Wouter
2703 - Fix crash with module-config "iterator".
2704 - Added unit test that has "iterator" module-config.
2706 30 November 2009: Wouter

2709 26 November 2009: Wouter
2710 - updated ldns with release candidate for version 1.6.3.
2711 - tag for 1.4.0 release.
2712 - 1.4.1 version in trunk.
2713 - Fixup major libtool version to 2 because of why_bogus change.
2714 It was 1:5:0 but should have been 2:0:0.
2716 23 November 2009: Wouter
2717 - Patch from David Hubbard for libunbound manual page.
2718 - Fixup endless spinning in unbound-control stats reported by
2719 Attila Nagy. Probably caused by clock reversal.
2721 20 November 2009: Wouter
2722 - contrib/split-itar.sh contributed by Tom Hendrikx.
2724 19 November 2009: Wouter
2725 - better argument help for unbound-control.
2726 - iana portlist updated.

2738 13 November 2009: Wouter
2739 - Fixed validation failure for CNAME to optout NSEC3 nodata answer.
2740 - unbound-host does not fail on type ANY.
2741 - Fixed wireparse failure to put RRSIGs together with data in some
2742 long ANY mix cases, which fixes validation failures.
2744 12 November 2009: Wouter
2745 - iana portlist updated.
2746 - fix manpage errors reported by debian lintian.
2748 - fixup very long vallog2 level error strings.
2750 11 November 2009: Wouter
2751 - ldns tarball updated (to 1.6.2).
2754 10 November 2009: Wouter
2755 - Thanks to Surfnet found bug in new dnssec-retry code that failed
2756 to combine well when combined with DLV and a particular failure.
2757 - Fixed unbound-control -h output about argument optionality.
2760 5 November 2009: Wouter
2761 - lint fixes and portability tests.
2762 - better error text for multiple domain keys in one autotrust file.
2764 2 November 2009: Wouter
2765 - Fix bug where autotrust does not work when started with a DS.
2766 - Updated GOST unit tests for unofficial algorithm number 249
2767 and DNSKEY-format changes in draft version -01.
2769 29 October 2009: Wouter
2770 - iana portlist updated.
2771 - edns-buffer-size option, default 4096.
2774 28 October 2009: Wouter
2775 - removed abort on prealloc failure, error still printed but softfail.
2776 - iana portlist updated.
2777 - RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
2778 - ldns tarball updated (which also enables rsasha256 support).
2780 27 October 2009: Wouter
2781 - iana portlist updated.
2783 8 October 2009: Wouter
2785 - add val-log-level print to corner case (nameserver.epost.bg).
2786 - more detail to errors from insecure delegation checks.
2787 - Fix double time subtraction in negative cache reported by
2788 Amanda Constant and Hugh Mahon.
2789 - Made new validator error string available from libunbound for
2790 applications. It is in result->why_bogus, a zero-terminated string.
2791 unbound-host prints it by default if a result is bogus.
2792 Also the errinf is public in module_qstate (for other modules).
2794 7 October 2009: Wouter
2795 - retry for validation failure in DS and prime results. Less mem use.
2796 unit test. Provisioning in other tests for requeries.
2797 - retry for validation failure in DNSKEY in middle of chain of trust.
2799 - retry for empty non terminals in chain of trust and unit test.
2800 - Fixed security bug where the signatures for NSEC3 records were not
2801 checked when checking for absence of DS records. This could have
2802 enabled the substitution of an insecure delegation.
2803 - moved version number to 1.4.0 because of 1.3.4 release with only
2804 the NSEC3 patch from the entry above.
2805 - val-log-level: 2 shows extended error information for validation
2806 failures, but still one (longish) line per failure. For example:
2807 validation failure <example.com. DNSKEY IN>: signature expired from
2808 192.0.2.4 for trust anchor example.com. while building chain of trust
2809 validation failure <www.example.com. A IN>: no signatures from
2810 192.0.2.6 for key example.com. while building chain of trust
2812 6 October 2009: Wouter
2813 - Test set updated to provide additional ns lookup result.
2814 The retry would attempt to fetch the data from other nameservers
2815 for bogus data, and this needed to be provisioned in the tests.
2817 5 October 2009: Wouter
2818 - first validation failure retry code. Retries for data failures.
2821 2 October 2009: Wouter
2822 - improve 5011 modularization.
2823 - fix unbound-host so -d can be given before -C.
2824 - iana portlist updated.
2826 28 September 2009: Wouter
2827 - autotrust-anchor-file can read multiline input and $ORIGIN.
2828 - prevent integer overflow in holddown calculation. review fixes.
2829 - fixed race condition in trust point revocation. review fix.
2830 - review fixes to comments, removed unused code.
2832 25 September 2009: Wouter
2833 - so-rcvbuf: 4m option added. Set this on large busy servers to not
2834 drop the occasional packet in spikes due to full socket buffers.
2835 netstat -su keeps a counter of UDP dropped due to full buffers.
2836 - review of validator/autotrust.c, small fixes and comments.
2838 23 September 2009: Wouter
2839 - 5011 query failed counts verification failures, not lookup failures.
2840 - 5011 probe failure handling fixup.
2841 - test unbound reading of original autotrust data.
2842 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
2843 picked up, otherwise performs initial probe like usual.
2845 22 September 2009: Wouter
2846 - autotrust test with algorithm rollover, new ordering of checks
2847 assists in orderly rollover.
2848 - autotrust test with algorithm rollover to unknown algorithm.
2849 checks if new keys are supported before adding them.
2850 - autotrust test with trust point revocation, becomes unsigned.
2851 - fix DNSSEC-missing-signature detection for minimal responses
2852 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
2854 18 September 2009: Wouter
2855 - autotrust tests, fix trustpoint timer deletion code.
2856 fix count of valid anchors during missing remove.
2857 - autotrust: pick up REVOKE even if not signed with known other keys.
2859 17 September 2009: Wouter
2860 - fix compile of unbound-host when --enable-alloc-checks.
2861 - Fix lookup problem reported by Koh-ichi Ito and Jaap Akkerhuis.
2862 - Manual page fixes reported by Tony Finch.
2864 16 September 2009: Wouter
2865 - Fix memory leak reported by Tao Ma.
2866 - Fix memstats test tool for log-time-ascii log format.
2868 15 September 2009: Wouter
2869 - iana portlist updated.
2871 10 September 2009: Wouter
2872 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
2873 - use linebuffering for log-file: output, this can be significantly
2874 faster than the previous fflush method and enable some class of
2875 resolvers to use high verbosity (for short periods).
2876 Not on windows, because line buffering does not work there.
2878 9 September 2009: Wouter
2879 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
2880 The RRsets would still expire at the normal time, but this would
2881 keep messages bogus in the cache for too long.
2882 - regression test for that bug.
2883 - documented that load_cache is meant for debugging.
2885 8 September 2009: Wouter
2886 - fixup printing errors when load_cache, they were printed to the
2887 SSL connection which broke, now to the log.
2888 - new ldns - with fixed parse of large SOA values.
2890 7 September 2009: Wouter
2891 - autotrust testbound scenarios.
2892 - autotrust fix that failure count is written to file.
2893 - autotrust fix that keys may become valid after add holddown time
2894 alone, before the probe returns.
2896 4 September 2009: Wouter
2897 - Changes to make unbound work with libevent-2.0.3 alpha. (in
2898 configure detection due to new ssl dependency in libevent)

3137 They are performed to higherup domains, and thus treated as if
3138 going to higher zones when looking up the right forward or stub
3139 server. This makes a stub pointing to a local server that has
3140 a local view of example.com signed with the same keys as are
3141 publicly used work. Reported by Johan Ihren.
3142 - Added build-unbound-localzone-from-hosts.pl to contrib, from
3143 Dennis DeDonatis. It converts /etc/hosts into config statements.
3144 - same thing fixed for forward-zone and DS, chain of trust from
3145 public internet into the forward-zone works now. Added unit test.
3148 - openssl key files are opened apache-style, when user is root and
3149 before chrooting. This makes permissions on remote-control key
3150 files easier to set up. Fixes bug #251.
3151 - flush_type and flush_name remove msg cache entries.
3152 - codereview - dp copy bogus setting fix.

3166 - fixup bad free() when wrongly encoded DSA signature is seen.
3167 Reported by Paul Wouters.
3168 - review comments from Matthijs.
3171 - --enable-sha2 option. The draft rsasha256 changed its algorithm
3172 numbers too often. Therefore it is more prudent to disable the
3173 RSASHA256 and RSASHA512 support by default.
3174 - ldns trunk included as new tarball.
3175 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.

3182 - update ldns lib tarball
3185 - detect lack of IPv6 support on XP (with a different error code).
3186 - Fixup a crash-on-exit which was triggered by a very long queue.
3187 Unbound would try to re-use ports that came free, but this is
3188 of course not really possible because everything is deleted.
3189 Most easily triggered on XP (not Vista), maybe because of the
3190 network stack encouraging large messages backlogs.
3191 - change in debug statements.
3192 - Fixed bug that could cause a crash if root prime failed when there
3193 were message backlogs.

3268 - nxdomain ttl considerations in requirements.txt
3270 3 April 2009: Wouter
3271 - Fixed a bug that caused messages to be stored in the cache too
3272 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
3273 targets have been more vulnerable to the TTL miscalculation bug.
3274 - documentation test fixed for python addition.

3344 - Added tests, unknown algorithms become insecure. fallback works.
3345 - Fix for and test for unknown algorithms in a trust anchor
3346 definition. Trust anchors with no supported algos are ignored.
3347 This means a (higher)DS or DLV entry for them could succeed, and
3348 otherwise they are treated as insecure.
3349 - domain-insecure: "example.com" statement added. Sets domain
3350 insecure regardless of chain of trust DSs or DLVs. The inverse

3440 is not available everywhere and then gives fatal errors. The
3441 security is provided by pgp signature.
3443 18 February 2009: Wouter
3444 - more cycle detection. Also for target queries.
3445 - fixup bug where during deletion of the mesh queries the callbacks
3446 that were reentrant caused assertion failures. Keep the mesh in
3447 a reentrant safe state. Affects libunbound, reload of server,
3448 on quit and flush_requestlist.
3449 - iana portlist updated.
3451 13 February 2009: Wouter
3452 - forwarder information now per-thread duplicated.
3453 This keeps it read only for speed, with no locking necessary.
3454 - forward command for unbound control to change forwarders to use
3456 - document that unbound-host reads no config file by default.
3457 - updated iana portlist.
3459 12 February 2009: Wouter
3460 - call setusercontext if available (on BSD).
3461 - small refactor of stats clearing.
3462 - #227: flush_stats feature for unbound-control.
3463 - stats_noreset feature for unbound-control.
3464 - flush_requestlist feature for unbound-control.
3465 - libunbound version upped API (was changed 5 feb).
3466 - unbound-control status shows if root forwarding is in use.
3467 - slightly nicer memory management in iter-fwd code.
3469 10 February 2009: Wouter
3470 - keys with rfc5011 REVOKE flag are skipped and not considered when
3472 - iana portlist updated
3473 - #226: dump_requestlist feature for unbound-control.
3475 6 February 2009: Wouter
3476 - contrib contains specfile for fedora 1.2.1 (from Paul Wouters).
3477 - iana portlist updated.
3478 - fixup EOL in include directive (reported by Paul Wouters).
3479 You can no longer specify newlines in the names of included files.
3480 - config parser changed. Gives some syntax errors closer to where they
3481 occurred. Does not enforce a space after keyword anymore.
3482 Does not allow literal newlines inside quoted strings anymore.
3483 - verbosity level 5 logs customer IP for new requestlist entries.
3484 - test fix, lexer and cancel test.
3485 - new option log-time-ascii: yes if you enable it prints timestamps
3486 in the log file as Feb 06 13:45:26 (like syslog does).
3487 - detect event_base_new in libevent-1.4.1 and later and use it.
3488 - #231 unbound-checkconf -o option prints that value from config file.
3489 Useful for scripting in management scripts and the like.
3491 5 February 2009: Wouter
3492 - ldns 1.5.0 rc as tarball included.
3493 - 1.3.0 development continues:
3494 change in libunbound API: ub_cancel can return an error, that
3495 the async_id did not exist, or that it was already delivered.
3496 The result could have been delivered just before the cancel
3497 routine managed to acquire the lock, so a caller may get the
3498 result at the same time they call cancel. For this case,
3499 ub_cancel tries to return an error code.
3500 Fixes race condition in ub_cancel() libunbound function.
3501 - MacOSX Leopard cleaner text output from configure.
3502 - initgroups(3) is called to drop secondary group permissions, if
3504 - configure option --with-ldns-builtin forces the use of the
3505 inluded ldns package with the unbound source. The -I include
3506 is put before the others, so it avoids bad include files from
3507 an older ldns install.
3508 - daemon(3) posix call is used when available.
3509 - testbound test for older fix added.
3511 4 February 2009: Wouter
3512 - tag for release 1.2.1.
3513 - trunk setup for 1.3.0 development.
3515 3 February 2009: Wouter
3516 - noted feature requests in doc/TODO.
3517 - printout more detailed errors on ssl certificate loading failures.
3518 - updated IANA portlist.
3520 16 January 2009: Wouter
3521 - more quiet about ipv6 network failures, i.e. when ipv6 is not
3522 available (network unreachable). Debug still printed on high
3524 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
3525 debugging with unbound-host -4 -d ...
3526 - more cycle detection for NS-check, addr-check, root-prime and
3527 stub-prime queries in the iterator. Avoids possible deadlock
3530 15 January 2009: Wouter
3531 - bug #229: fixup configure checks for compilation with Solaris
3532 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc
3533 - fixup suncc warnings.
3534 - fix bug where unbound could crash using libevent 1.3 and older.
3535 - update testset for recent retry change.
3537 14 January 2009: Wouter
3538 - 1.2.1 feature: negative caching for failed queries.
3539 Queries that failed are cached for 5 seconds (NORR_TTL).
3540 If the failure is local, like out of memory, it is not cached.
3541 - the TTL comparison for the cache used different comparisons,
3542 causing many cache responses that used the iterator and validator
3543 state machines unnecessarily.
3544 - retry from 4 to 5 so that EDNS drop retry is part of the first
3545 query resolve attempt, and cached error does not stop EDNS fallback.
3546 - remove debug prints that protect against bad referrals.
3547 - honor QUIET=no on make commandline (or QUIET=yes ).
3549 13 January 2009: Wouter
3550 - fixed bug in lameness marking, removed printouts.
3551 - find NS rrset more cleanly for qtype NS.
3552 - Moved changes to 1.2.0 for release. Thanks to Mark Zealey for
3554 - 1.2.1 feature: stops resolving AAAAs promiscuously when they
3555 are in the negative cache.
3557 12 January 2009: Wouter
3558 - fixed bug in infrastructure lameness cache, did not lowercase
3559 name of zone to hash when setting lame.
3560 - lameness debugging printouts.
3562 9 January 2009: Wouter
3563 - created svn tag for 1.2.0 release.
3564 - svn trunk contains 1.2.1 version number.
3565 - iana portlist updated for todays list.
3566 - removed debug print.
3568 8 January 2009: Wouter
3569 - new version of ldns-trunk (today) included as tarball, fixed
3570 bug #224, building with -j race condition.
3571 - remove possible race condition in the test for race conditions.
3573 7 January 2009: Wouter
3574 - version 1.2.0 in preparation.
3575 - feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
3576 statements. (Adapted from patch by Paul Wouters).
3577 - typo fix and iana portlist updated.
3578 - porting testsuite; unused var warning, and type fixup.
3580 6 January 2009: Wouter
3581 - fixup packet-of-death when compiled with --enable-debug.
3582 A malformed packet could cause an internal assertion failure.
3583 - added test for HINFO canonicalisation behaviour.
3584 - fixup reported problem with transparent local-zone data where
3585 queries with different type could get nxdomain. Now queries
3586 with a different name get resolved normally, with different type
3587 get a correct NOERROR/NODATA answer.
3588 - HINFO no longer downcased for validation, making unbound compatible
3590 - fix reading included config files when chrooted.
3591 Give full path names for include files.
3592 Relative path names work if the start dir equals the working dir.
3593 - fix libunbound message transport when no packet buffer is available.
3595 5 January 2009: Wouter
3596 - fixup getaddrinfo failure handling for remote control port.
3597 - added L.ROOT-SERVERS.NET. AAAA 2001:500:3::42 to builtin root hints.
3598 - fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
3599 - comm_timer_set performs base_set operation after event_add.
3601 18 December 2008: Wouter
3602 - fixed bug reported by Duane Wessels: error in DLV lookup, would make
3603 some zones that had correct DLV keys as insecure.
3604 - follows -rc makedist from ldns changes (no _rc).
3605 - ldns tarball updated with 1.4.1rc for DLV unit test.
3606 - verbose prints about recursion lame detection and server selection.
3607 - fixup BSD port for infra host storage. It hashed wrongly.
3608 - fixup makedist snapshot name generation.
3609 - do not reopen syslog to avoid dev/log dependency.
3611 17 December 2008: Wouter
3612 - follows ldns makedist.sh. -rc option. autom4te dir removed.
3613 - unbound-control status command.
3614 - extended statistics has a number of ipv6 queries counter.
3615 contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
3617 16 December 2008: Wouter
3618 - follow makedist improvements from ldns, for maintainers prereleases.
3619 - snapshot version uses _ not - to help rpm distinguish the
3622 11 December 2008: Wouter
3623 - better fix for bug #219: use LOG_NDELAY with openlog() call.
3624 Thanks to Tamas Tevesz.
3626 9 December 2008: Wouter
3627 - bug #221 fixed: unbound checkconf checks if key files exist if
3628 remote control is enabled. Also fixed NULL printf when not chrooted.
3629 - iana portlist updated.
3631 3 December 2008: Wouter
3632 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
3633 freezes up unbound if this was compiled without threading, and
3634 was using multiple processes.
3635 - iana portlist updated.
3636 - test for remote control with interprocess communication.
3637 - created command distribution mechanism so that remote control
3638 commands other than 'stats' work on all processes in a nonthreaded
3639 compiled version. dump/load cache work, on the first process.
3640 - fixup remote control local_data addition memory corruption bug.
3642 1 December 2008: Wouter
3643 - SElinux policy files in contrib/selinux for the unbound daemon,
3644 by Paul Wouters and Adam Tkac.
3646 25 November 2008: Wouter
3647 - configure complains when --without-ssl is given (bug #220).
3648 - skip unsupported feature tests on vista/mingw.
3649 - fixup testcode/streamtcp to work on vista/mingw.
3650 - root-hints test checks version of dig required.
3651 - blacklisted servers are polled at a low rate (1%) to see if they
3652 come back up. But not if there is some other working server.
3654 24 November 2008: Wouter
3655 - document that the user of the server daemon needs read privileges
3656 on the keys and certificates generated by unbound-control-setup.
3657 This is different per system or distribution, usually, running the
3658 script under the same username as the server uses suffices.
3659 i.e. sudo -u unbound unbound-control-setup
3660 - testset port to vista/mingw.
3661 - tcp_sigpipe to freebsd port.
3663 21 November 2008: Wouter
3664 - fixed tcp accept, errors were printed when they should not.
3665 - unbound-control-setup.sh removes read/write permissions other
3666 from the keys it creates (as suggested by Dmitriy Demidov).
3668 20 November 2008: Wouter
3669 - fixup fatal error due to faulty error checking after tcp accept.
3670 - add check in rlimit to avoid integer underflow.
3671 - rlimit check with new formula; better estimate for number interfaces
3672 - nicer comments in rlimit check.
3673 - tag 1.1.1 created in svn.
3674 - trunk label is 1.1.2
3676 19 November 2008: Wouter
3677 - bug #219: fixed so that syslog which delays opening until the first
3678 log line is written, gets a log line while not chroot'ed yet.
3680 18 November 2008: Wouter
3681 - iana portlist updated.
3682 - removed cast in unit test debug print that was not 64bit safe.
3683 - trunk back to 1.1.0; copied to tags 1.1.0 release.
3684 - trunk to has version number 1.1.1 again.
3685 - in 1.1.1; make clean nicer. grammar in manpage.
3687 17 November 2008: Wouter
3688 - theoretical fix for problems reported on mailing list.
3689 If a delegation point has no A but only AAAA and do-ip6 is no,
3690 resolution would fail. Fixed to ask for the A and AAAA records.
3691 It has to ask for both always, so that it can fail quietly, from
3692 TLD perspective, when a zone is only reachable on one transport.
3693 - test for above, only AAAA and doip6 is no. Fix causes A record
3694 for nameserver to be fetched.
3695 - fixup address duplication on cache fillup for delegation points.
3696 - testset updated for new query answer requirements.
3698 14 November 2008: Wouter
3699 - created 1.1.0 release tag in svn.
3700 - trunk moved to 1.1.1
3701 - fixup unittest-neg for locking.
3703 13 November 2008: Wouter
3704 - added fedora init and specfile to contrib (by Paul Wouters).
3705 - added configure check for ldns 1.4.0 (using its compat funcs).
3706 - neater comments in worker.h.
3707 - removed doc/plan and updated doc/TODO.
3708 - silenced EHOSTDOWN (verbosity 2 or higher to see it).
3709 - review comments from Jelte, Matthijs. Neater code.
3711 12 November 2008: Wouter
3712 - add unbound-control manpage to makedist replace list.
3714 11 November 2008: Wouter
3715 - unit test for negative cache, stress tests the refcounting.
3716 - fix for refcounting error that could cause fptr_wlist fatal exit
3717 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
3718 Attila Nagy for testing).
3719 - nicer comments in cachedump about failed RR to string conversion.
3720 - fix 32bit wrap around when printing large (4G and more) mem usage
3721 for extended statistics.
3723 10 November 2008: Wouter
3724 - fixup the getaddrinfo compat code rename.
3726 8 November 2008: Wouter
3727 - added configure check for eee build warning.

3730 - fix bug 217: fixed, setreuid and setregid do not work on MacOSX10.4.
3731 - detect nonblocking problems in network stack in configure script.
3733 6 November 2008: Wouter
3734 - dname_priv must decompress the name before comparison.
3735 - iana portlist updated.
3737 5 November 2008: Wouter
3738 - fixed possible memory leak in key_entry_key deletion.
3739 Would leak a couple bytes when trust anchors were replaced.
3740 - if query and reply qname overlap, the bytes are skipped not copied.
3741 - fixed file descriptor leak when messages were jostled out that
3742 had outstanding (TCP) replies.
3743 - DNAMEs used from cache have their synthesized CNAMEs initialized
3745 - fixed file descriptor leak for localzone type deny (for TCP).
3746 - fixed memleak at exit for nsec3 negative cached zones.
3747 - fixed memleak for the keyword 'nodefault' when reading config.
3748 - made verbosity of 'edns incapable peer' warning higher, so you
3749 do not get spammed by it.
3750 - caught elusive Bad file descriptor error bug, that would print the
3751 error while unnecessarily try to listen to a closed fd. Fixed.
3753 4 November 2008: Wouter
3754 - fixed -Wwrite-strings warnings that result in better code.
3756 3 November 2008: Wouter
3757 - fixup build process for Mac OSX linker, use ldns b32 compat funcs.
3758 - generated configure with autoconf-2.61.
3759 - iana portlist updated.
3760 - detect if libssl needs libdl. For static linking with libssl.
3761 - changed to use new algorithm identifiers for sha256/sha512
3762 from ldns 1.4.0 (need very latest version).
3763 - updated the included ldns tarball.
3764 - proper detection of SHA256 and SHA512 functions (not just sizes).
3766 23 October 2008: Wouter
3767 - a little more debug info for failure on signer names. prints names.
3769 22 October 2008: Wouter
3770 - CFLAGS are picked up by configure from the environment.
3771 - iana portlist updated.
3772 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
3773 - new stub-prime: yesno option. Default is off, so it does not prime.
3774 can be turned on to get same behaviour as previous unbound release.
3775 - made automated test that checks if builtin root hints are uptodate.
3776 - finished draft-wijngaards-dnsext-resolver-side-mitigation
3777 implementation. The unwanted-reply-threshold can be set.
3778 - fixup so fptr_whitelist test in alloc.c works.
3780 21 October 2008: Wouter
3781 - fix update-anchors.sh, so it does not report different RR order
3782 as an update. Sorts the keys in the file. Updated copyright.
3783 - fixup testbound on windows, the command control pipe doesn't exist.
3784 - skip 08hostlib test on windows, no fork() available.
3785 - made unbound-remote work on windows.
3787 20 October 2008: Wouter
3788 - quench a log message that is debug only.
3789 - iana portlist updated.
3790 - do not query bogus nameservers. It is like nameservers that have
3791 the NS or A or AAAA record bogus are listed as donotquery.
3792 - if server selection is faced with only bad choices, it will
3793 attempt to get more options to be fetched.
3794 - changed bogus-ttl default value from 900 to 60 seconds.
3795 In anticipation that operator caused failures are more likely than
3796 actual attacks at this time. And thus repeated validation helps
3797 the operators get the problem fixed sooner. It makes validation
3798 failures go away sooner (60 seconds after the zone is fixed).
3799 Also it is likely to try different nameserver targets every minute,
3800 so that if a zone is bad on one server but not another, it is
3801 likely to pick up the 'correct' one after a couple minutes,
3802 and if the TTL is big enough that solves validation for the zone.
3803 - fixup unbound-control compilation on windows.
3805 17 October 2008: Wouter
3806 - port Leopard/G5: fixup type conversion size_t/uint32.
3807 please ranlib, stop file without symbols warning.
3808 - harden referral path now also validates the root after priming.
3809 It looks up the root NS authoritatively as well as the root servers
3810 and attemps to validate the entries.
3812 16 October 2008: Wouter
3813 - Fixup negative TTL values appearing (reported by Attila Nagy).
3815 15 October 2008: Wouter
3816 - better documentation for 0x20; remove fallback TODO, it is done.
3817 - harden-referral-path feature includes A, AAAA queries for glue,
3818 as well as very careful NS caching (only when doing NS query).
3819 A, AAAA use the delegation from the NS-query.
3821 14 October 2008: Wouter
3822 - fwd_three.tpkg test was flaky. If the three requests hit the
3823 wrong threads by chance (or bad OS) then the test would fail.
3824 Made less flaky by increasing number of retries.
3825 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
3826 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
3827 Which includes the ldns_dname_absolute fix.
3828 - fwd_three test remains flaky now that unbound does not stop
3829 listening when full. Thus, removed timeout problem.
3830 It may be serviced by three threads, or maybe by one.
3831 Mostly only useful for lock-check testing now.
3833 13 October 2008: Wouter
3834 - fixed recursion servers deployed as authoritative detection, so
3835 that as a last resort, a +RD query is sent there to get the
3837 - iana port list update.
3838 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
3840 10 October 2008: Wouter
3841 - fixup tests - the negative cache contained the correct NSEC3s for
3842 two tests that are supposed to fail to validate.
3844 9 October 2008: Wouter
3845 - negative cache caps max iterations of NSEC3 done.
3846 - NSEC3 negative cache for qtype DS works.
3848 8 October 2008: Wouter
3849 - NSEC negative cache for DS.
3851 6 October 2008: Wouter
3852 - jostle-timeout option, so you can config for slow links.
3853 - 0x20 fallback code. Tries 3xnumber of nameserver addresses
3854 queries that must all be the same. Sent to random nameservers.
3855 - documented choices for DoS, EDNS, 0x20.
3857 2 October 2008: Wouter
3858 - fixup unlink of pidfile.
3859 - fixup SHA256 algorithm collation code.
3860 - contrib/update-anchor.sh does not overwrite anchors if not needed.
3861 exits 0 when a restart is needed, other values if not.
3862 so, update-anchor.sh -d mydir && /etc/rc.d/unbound restart
3863 can restart unbound exactly when needed.
3865 30 September 2008: Wouter
3866 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
3867 - tests for sha256 support and downgrade resistance.
3868 - RSASHA256 and RSASHA512 support (using the draft in dnsext),
3869 using the drafted protocol numbers.
3870 - when using stub on localhost (127.0.0.1@10053) unbound works.
3871 Like when running NSD to host a local zone, on the same machine.
3872 The noprime feature. manpages more explanation. Added a test for it.
3873 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
3875 29 September 2008: Wouter
3876 - EDNS lameness detection, if EDNS packets are dropped this is
3877 detected, eventually.
3878 - multiple query timeout rtt backoff does not backoff too much.
3880 26 September 2008: Wouter
3881 - tests for remote-control.
3882 - small memory leak in exception during remote control fixed.
3883 - fixup for lock checking but not unchecking in remote control.
3884 - iana portlist updated.
3886 23 September 2008: Wouter
3887 - Msg cache is loaded. A cache load enables cache responses.
3888 - unbound-control flush [name], flush_type and flush_zone.
3890 22 September 2008: Wouter
3891 - dump_cache and load_cache statements in unbound-control.
3892 RRsets are dumped and loaded correctly.
3893 Msg cache is dumped.
3895 19 September 2008: Wouter
3896 - locking on the localdata structure.
3897 - add and remove local zone and data with unbound-control.
3898 - ldns trunk snapshot updated, make tests work again.
3900 18 September 2008: Wouter
3901 - fixup error in time calculation.
3902 - munin plugin improvements.
3903 - nicer abbreviations for high query types values (ixfr, axfr, any...)
3904 - documented the statistics output in unbound-control man page.
3905 - extended statistics prints out histogram, over unbound-control.
3907 17 September 2008: Wouter
3908 - locking for threadsafe bogus rrset counter.
3909 - ldns trunk no longer exports b32 functions, provide compat.
3910 - ldns tarball updated.
3911 - testcode/ldns-testpkts.c const fixups.
3912 - fixed rcode stat printout.
3913 - munin plugin in contrib.
3914 - stats always printout uptime, because stats plugins need it.
3916 16 September 2008: Wouter
3917 - extended-statistics: yesno config option.
3918 - unwanted replies spoof nearmiss detector.
3919 - iana portlist updated.
3921 15 September 2008: Wouter
3922 - working start, stop, reload commands for unbound-control.
3923 - test for unbound-control working; better exit value for control.
3924 - verbosity control via unbound-control.
3925 - unbound-control stats.

3957 - do not mark unsigned additionals bogus, leave unchecked, which
3960 1 September 2008: Wouter
3961 - disallow nonrecursive queries for cache snooping by default.

3973 again. (from bugfix#199).
3974 Some errors are not written to logfile (pidfile writing, forking),
3975 and these are only visible by using the -d commandline flag.
3977 27 August 2008: Wouter
3978 - daemon(3) is causing problems for people. Reverting the patch.
3979 bug#200, and 199 and 203 contain sideline discussion on it.

4039 11 August 2008: Wouter
4040 - Fixup rrset security updates overwriting 2181 trust status.
4041 This makes validated to be insecure data just as worthless as
4042 nonvalidated data, and 2181 rules prevent cache overwrites to them.

4140 - skip tests that need signals when testing on mingw.
4142 18 June 2008: Wouter
4143 - open testbound replay files in binary mode, because fseek/ftell
4144 do not work in ascii-mode on windows. The b does nothing on unix.
4145 unittest and testbound tests work on windows (xp too).
4146 - ioctlsocket prints nicer error message.
4147 - fixed up some TCP porting for winsock.
4148 - lack of IPv6 gives a warning, no fatal error.
4149 - use WSAGetLastError() on windows instead of errno for some errors.
4151 17 June 2008: Wouter
4152 - outgoing num fds 32 by default on windows ; it supports less
4153 fds for waiting on than unixes.
4154 - winsock_event minievent handler for windows. (you could also
4155 attempt to link with libevent/libev ports for windows).
4156 - neater crypto check and gdi32 detection.
4157 - unbound.exe works to resolve and validate www.nlnetlabs.nl on vista.

4215 - bug 185: --disable-shared not passed along to ldns included with
4216 unbound. Fixed so that configure parameters are passed to the
4217 subdir configure script.
4218 fixed that ./libtool is used always, you can still override
4219 manually with ./configure libtool=mylibtool or set $libtool in
4221 - update of the ldns tarball to current ldns svn version (fix 181).

4321 - and check first sig byte for the encoding type.
4323 11 April 2008: Wouter
4324 - random port selection out of the configged ports.
4325 - fixup threadsafety for libevent-1.4.3+ (event_base_get_method).

4332 - added log file statistics perl script to contrib.
4333 - automatic iana ports update from makefile. 60058 available.
4335 9 April 2008: Wouter
4336 - configure can detect libev(from its build directory) when passed
4337 --with-libevent=/home/wouter/libev-3.2
4338 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
4339 - unused commpoints not listed in epoll list.
4340 - statistics-cumulative option so that the values are not reset.
4341 - config creates array of available ports, 61841 available,
4342 it excludes <1024 and iana assigned numbers.
4343 config statements to modify the available port numbers.
4345 8 April 2008: Wouter
4346 - unbound tries to set the ulimit fds when started as server.
4347 if that does not work, it will scale back its requirements.
4349 27 March 2008: Wouter
4350 - documented /dev/random symlink from chrootdir as FAQ entry.
4352 26 March 2008: Wouter
4353 - implemented AD bit signaling. If a query sets AD bit (but not DO)
4354 then the AD bit is set in the reply if the answer validated.
4355 Without including DNSSEC signatures. Useful if you have a trusted
4356 path from the client to the resolver. Follows dnssec-updates draft.
4358 25 March 2008: Wouter
4359 - implemented check that for NXDOMAIN and NOERROR answers a query
4360 section must be present in the reply (by the scrubber). And it must
4361 be equal to the question sent, at least lowercase folded.
4362 Previously this feature happened because the cache code refused
4363 to store such messages. However blocking by the scrubber makes
4364 sure nothing gets into the RRset cache. Also, this looks like a
4365 timeout (instead of an allocation failure) and this retries are
4366 done (which is useful in a spoofing situation).
4367 - RTT banding. Band size 400 msec, this makes band around zero (fast)
4368 include unknown servers. This makes unbound explore unknown servers.
4370 7 March 2008: Wouter
4371 - -C config feature for harvest program.
4372 - harvest handles CNAMEs too.
4374 5 March 2008: Wouter
4375 - patch from Hugo Koji Kobayashi for iterator logs spelling.
4377 4 March 2008: Wouter
4378 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
4379 of a cname trust chain is lower; not full answer_AA.
4380 - test for this fix.
4381 - default config file location is /usr/local/etc/unbound.
4382 Thus prefix is used to determine the location. This is also the
4383 chroot and pidfile default location.
4385 3 March 2008: Wouter
4386 - Create 0.10 svn tag.
4387 - 0.11 version in trunk.
4388 - indentation nicer.
4390 29 February 2008: Wouter
4391 - documentation update.
4392 - fixup port to Solaris of perf test tool.
4393 - updated ldns-tarball with decl-after-statement fixes.

4397 - libunbound returns the answer packet in full.
4398 - snprintf compat update.
4399 - harvest performs lookup.
4400 - ldns-tarball update with fix for ldns_dname_label.
4401 - installs to sbin by default.
4402 - install all manual pages (unbound-host and libunbound too).
4404 27 February 2008: Wouter
4405 - option to use caps for id randomness.
4406 - config file option use-caps-for-id: yes
4407 - harvest debug tool
4409 26 February 2008: Wouter
4410 - delay utility delays TCP as well. If the server that is forwarded
4411 to has a TCP error, the delay utility closes the connection.
4412 - delay does REUSE_ADDR, and can handle a server that closes its end.
4413 - answers use casing from query.
4415 25 February 2008: Wouter
4416 - delay utility works. Gets decent thoughput too (>20000).
4418 22 February 2008: Wouter
4419 - +2% for recursions, if identical queries (except for destination
4420 and query ID) in the reply list, avoid re-encoding the answer.
4421 - removed TODO items for optimizations that do not show up in
4423 - default is now minievent - not libevent. As its faster and
4424 not needed for regular installs, only for very large port ranges.
4425 - loop check different speedup pkt-dname-reading, 1% faster for
4426 nocache-recursion check.
4427 - less hashing during msg parse, 4% for recursion.
4428 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
4429 - some speed results noted:
4430 optimization resulted in +40% for recursion (cache miss) and
4431 +70 to +80 for cache hits, and +96% for version.bind.
4432 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
4433 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
4434 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
4435 So, unbound can be about equal qps to NSD in cache hits.
4436 And about 3.4x faster than BIND in cache performance.
4437 - delay utility for testing.
4439 21 February 2008: Wouter
4440 - speedup of root-delegation message encoding by 15%.
4441 - minor speedup of compress tree_lookup, maybe 1%.
4442 - speedup of dname_lab_cmp and memlowercmp - the top functions in
4443 profiler output, maybe a couple percent when it matters.
4445 20 February 2008: Wouter
4446 - setup speec_cache for need-ldns-testns in dotests.
4447 - check number of queued replies on incoming queries to avoid overload
4449 - fptr whitelist checks are not disabled in optimize mode.
4450 - do-daemonize config file option.
4451 - minievent time share initializes time at start.
4452 - updated testdata for nsec3 new algorithm numbers (6, 7).
4453 - small performance test of packet encoding (root delegation).
4455 19 February 2008: Wouter
4456 - applied patch to unbound-host man page from Jan-Piet Mens.
4457 - fix donotquery-localhost: yes default (it erroneously was switched
4459 - time is only gotten once and the value is shared across unbound.
4460 - unittest cleans up crypto, so that it has no memory leaks.
4461 - mini_event shares the time value with unbound this results in
4462 +3% speed for cache responses and +9% for recursions.
4463 - ldns tarball update with new NSEC3 sign code numbers.
4464 - perform several reads per UDP operation. This improves performance
4465 in DoS conditions, and costs very little in normal conditions.
4466 improves cache response +50%, and recursions +10%.
4467 - modified asynclook test. because the callback from async is not
4468 in any sort of lock (and thus can use all library functions freely),
4469 this causes a tiny race condition window when the last lock is
4470 released for a callback and a new cancel() for that callback.
4471 The only way to remove this is by putting callbacks into some
4472 lock window. I'd rather have the small possibility of a callback
4473 for a cancelled function then no use of library functions in
4474 callbacks. Could be possible to only outlaw process(), wait(),
4475 cancel() from callbacks, by adding another lock, but I'd rather not.
4477 18 February 2008: Wouter
4478 - patch to unbound-host from Jan-Piet Mens.
4479 - unbound host prints errors if fails to configure context.
4480 - fixup perf to resend faster, so that long waiting requests do
4481 not hold up the queue, they become lost packets or SERVFAILs,
4482 or can be sent a little while later (i.e. processing time may
4483 take long, but throughput has to be high).
4484 - fixup iterator operating in no cache conditions (RD flag unset
4486 - streamlined code for RD flag setting.
4487 - profiled code and changed dname compares to be faster.
4488 The speedup is about +3% to +8% (depending on the test).

4553 31 January 2008: Wouter
4554 - bg thread/process reads and writes the pipe nonblocking all the time
4555 so that even if the pipe is buffered or so, the bg thread does not
4556 block, and services both pipes and queries.
4558 30 January 2008: Wouter
4559 - check trailing / on chrootdir in checkconf.
4560 - check if root hints and anchor files are in chrootdir.

4592 - rewrote _wait() routine, so that it is threadsafe.
4593 - cancelation is threadsafe.
4594 - asynclook extended test in tpkg.
4595 - fixed two races where forked bg process waits for (somehow shared?)
4596 locks, so does not service the query pipe on the bg side.

4611 - libunbound QUIT setup, remove memory leaks, when using threads
4612 will share memory for passing results instead of writing it over
4613 the pipe, only writes ID number over the pipe (towards the handler
4614 thread that does process() ).
4616 22 January 2008: Wouter
4617 - library code for async in libunbound/unbound.c.
4618 - fix link testbound.
4619 - fixup exit bug in mini_event.

4644 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
4646 16 January 2008: Wouter
4647 - incoming queries to the server with TC bit on are replied FORMERR.
4648 - interface-automatic replied the wrong source address on localhost
4649 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
4650 to use ifnum=-1 to mean 'no interface, use kernel route'.
4652 15 January 2008: Wouter
4653 - interface-automatic feature. experimental. Nice for anycast.
4654 - tpkg test for ip6 ancillary data.
4655 - removed debug prints.
4656 - porting experience, define for Solaris, test refined for BSD
4657 compatibility. The feature probably will not work on OpenBSD.
4658 - makedist fixup for ldns-src in build-dir.
4660 14 January 2008: Wouter
4661 - in no debug sets NDEBUG to remove asserts.

4688 - print median and quartiles with extensive logging.
4690 4 January 2008: Wouter
4691 - document misconfiguration in private network.

4694 - fixup typo in requirements.
4695 - document that 'refused' is a better choice than 'drop' for
4696 the access control list, as refused will stop retries.
4698 7 December 2007: Wouter
4699 - unbound-host has a -d option to show what happens. This can help
4700 with debugging (why do I get this answer).
4701 - fixup CNAME handling, on nodata, sets and display canonname.
4702 - dot removed from CNAME display.
4703 - respect -v for NXDOMAINs.
4704 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
4705 - size_t to int for portability of the header file.
4706 - fixup bogus handling.
4707 - dependencies and lint for unbound-host.
4709 6 December 2007: Wouter
4710 - library resolution works in foreground mode, unbound-host app
4712 - unbound-host prints rdata using ldns.
4713 - unbound-host accepts trust anchors, and prints validation
4714 information when you give -v.
4716 5 December 2007: Wouter
4717 - locking in context_new() inside the function.
4718 - setup of libworker.
4720 4 December 2007: Wouter
4721 - minor Makefile fixup.
4722 - moved module-stack code out of daemon/daemon into services/modstack,
4723 preparing for code-reuse.

4725 - context query structure.
4726 - removed unused variable pwd from checkconf.
4727 - removed unused assignment from outside netw.

4732 - fixup memleak on packet parse error.
4733 - put ; after union in parser.y.
4734 - small hardening in iter_operate against iq==NULL.
4735 - hardening, if error reply with rcode=0 (noerror) send servfail.
4736 - fixup same (*var) error in find_rrset in msgparse, was harmless.
4737 - check return value of evtimer_add().
4738 - fixup lockorder in lruhash_reclaim(), building up a list of locked
4739 entries one at a time. Instead they are removed and unlocked.
4740 - fptr_wlist for markdelfunc.
4741 - removed is_locked param from lruhash delkeyfunc.
4742 - moved bin_unlock during bin_split purely to please.
4744 3 December 2007: Wouter
4745 - changed checkconf/ to smallapp/ to make room for more support tools.
4746 (such as unbound-host).
4747 - install dirs created with -m 755 because they need to be accessible.
4748 - library extensive featurelist added to TODO.
4749 - please doxygen, lint.
4750 - library test application, with basic functionality.
4751 - fix for building in a subdirectory.
4752 - link lib fix for Leopard.
4754 30 November 2007: Wouter
4755 - makefile that creates libunbound.la, basic file or libunbound.a
4756 when creating static executables (no libtool).
4759 29 November 2007: Wouter
4760 - 0.9 public API start.
4762 28 November 2007: Wouter
4763 - Changeup plan for 0.8 - no complication needed, a simple solution
4764 has been chosen for authoritative features.
4765 - you can use single quotes in the config file, so it is possible
4766 to specify TXT records in local data.
4767 - fixup small memory problem in implicit transparent zone creation.
4768 - test for implicit zone creation and multiple RR RRsets local data.
4769 - local-zone nodefault test.
4770 - show testbound testlist on commit.
4771 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
4772 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
4774 - nicer verbosity: 0 and 1 levels.
4775 - lower nonRDquery chance of eliciting wrongly typed validation
4776 requiring message from the cache.
4777 - fix for nonRDquery validation typing; nodata is detected when
4778 SOA record in auth section (all validation-requiring nodata messages
4779 have a SOA record in authority, so this is OK for the validator),
4780 and NS record is needed to be a referral.
4781 - duplicate checking when adding NSECs for a CNAME, and test.
4782 - created svn tag 0.8, after completing testbed tests.
4784 27 November 2007: Wouter
4785 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
4786 - set size of msgparse lookup table to 32, from 1024, so that its size
4787 is below the 2048 regional large size threshold, and does not cause
4788 a call to malloc when a message is parsed.
4789 - update of memstats tool to print number of allocation calls.
4790 This is what is taking time (not space) and indicates the avg size
4791 of the allocations as well. region_alloc stat is removed.
4793 22 November 2007: Wouter
4794 - noted EDNS in-the-middle dropping trouble as a TODO.
4795 At this point theoretical, no user trouble has been reported.
4796 - added all default AS112 zones.
4797 - answers from local zone content.
4798 * positive answer, the rrset in question
4799 * nodata answer (exist, but not that type).
4800 * nxdomain answer (domain does not exist).
4801 * empty-nonterminal answer.
4802 * But not: wildcard, nsec, referral, rrsig, cname/dname,
4803 or additional section processing, NS put in auth.
4804 - test for correct working of static and transparent and couple
4805 of important defaults (localhost, as112, reverses).
4806 Also checks deny and refuse settings.
4807 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
4809 21 November 2007: Wouter
4810 - local zone internal data setup.
4812 20 November 2007: Wouter
4813 - 0.8 - str2list config support for double string config options.
4814 - local-zone and local-data options, config storage and documentation.
4816 19 November 2007: Wouter
4817 - do not downcase NSEC and RRSIG for verification. Follows
4818 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
4819 - fixup leaking unbound daemons at end of tests.
4820 - README file updated.
4821 - nice libevent not found error.
4822 - README talks about gnu make.
4823 - 0.8: unit test for addr_mask and fixups for it.
4824 and unit test for addr_in_common().
4825 - 0.8: access-control config file element.
4826 and unit test rpl replay file.
4827 - 0.8: fixup address reporting from netevent.
4829 16 November 2007: Wouter
4830 - privilege separation is not needed in unbound at this time.
4831 TODO item marked as such.
4832 - created beta-0.7 branch for support.
4833 - tagged 0.7 for beta release.
4834 - moved trunk to 0.8 for 0.8(auth features) development.
4835 - 0.8: access control list setup.
4837 15 November 2007: Wouter
4838 - review fixups from Jelte.
4840 14 November 2007: Wouter
4841 - testbed script does not recreate configure, since its in svn now.
4842 - fixup checkconf test so that it does not test
4843 /etc/unbound/unbound.conf.
4846 13 November 2007: Wouter
4847 - remove debug print.
4848 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
4850 12 November 2007: Wouter
4851 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
4853 - bugreports to unbound-bugs@nlnetlabs.nl
4854 - fixup testbound so it exits cleanly.
4855 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
4857 9 November 2007: Wouter
4858 - took ldns snapshot in repo.
4859 - default config file is /etc/unbound/unbound.conf.
4860 If it doesn't exist, it is installed with the doc/example.conf file.
4861 The file is not deleted on uninstall.
4862 - default listening is not all, but localhost interfaces.
4864 8 November 2007: Wouter
4865 - Fixup chroot and drop user privileges.
4866 - new L root ip address in default hints.
4868 1 November 2007: Wouter
4869 - Fixup of crash on reload, due to anchors in env not NULLed after
4870 dealloc during deinit.
4871 - Fixup of chroot call. Happens after privileges are dropped, so
4872 that checking the passwd entry still works.
4873 - minor touch up of clear() hashtable function.
4874 - VERB_DETAIL prints out what chdir, username, chroot is being done.
4875 - when id numbers run out, caches are cleared, as in design notes.
4876 Tested with a mock setup with very few bits in id, it worked.
4877 - harden-dnssec-stripped: yes is now default. It insists on dnssec
4878 data for trust anchors. Included tests for the feature.
4880 31 October 2007: Wouter
4881 - cache-max-ttl config option.
4882 - building outside sourcedir works again.
4883 - defaults more secure:
4885 chroot: "/etc/unbound"
4886 The operator can override them to be less secure ("") if necessary.
4887 - fix horrible oversight in sorting rrset references in a message,
4888 sort per reference key pointer, not on referencepointer itself.
4889 - pidfile: "/etc/unbound/unbound.pid" is now the default.
4890 - tests changed to reflect the updated default.
4891 - created hashtable clear() function that respects locks.
4893 30 October 2007: Wouter
4894 - fixup assertion failure that relied on compressed names to be
4895 smaller than uncompressed names. A packet from comrite.com was seen
4896 to be compressed to a larger size. Added it as unit test.
4897 - quieter logging at low verbosity level for common tcp messages.
4898 - no greedy TTL update.
4900 23 October 2007: Wouter
4901 - fixup (grand-)parent problem for dnssec-lameness detection.
4902 - fixup tests to do additional section processing for lame replies,
4903 since the detection needs that.
4904 - no longer trust in query section in reply during dnssec lame detect.
4905 - dnssec lameness does not make the server never ever queried, but
4906 non-preferred. If no other servers exist or answer, the dnssec lame
4907 server is used; the fastest dnssec lame server is chosen.
4908 - added test then when trust anchor cannot be primed (nodata), the
4909 insecure mode from unbound works.
4910 - Fixup max queries per thread, any more are dropped.
4912 22 October 2007: Wouter
4913 - added donotquerylocalhost config option. Can be turned off for
4915 - ISO C compat changes.
4916 - detect RA-no-AA lameness, as LAME.
4917 - DNSSEC-lameness detection, as LAME.
4918 See notes in requirements.txt for choices made.
4919 - tests for lameness detection.
4920 - added all to make test target; need unbound for fwd tests.
4921 - testbound does not pollute /etc/unbound.
4923 19 October 2007: Wouter
4924 - added configure (and its files) to svn, so that the trunk is easier
4925 to use. ./configure, config.guess, config.sub, ltmain.sh,
4927 - added yacc/lex generated files, util/configlexer.c,
4928 util/configparser.c util/configparser.h, to svn.
4929 - without lex no attempt to use it.
4930 - unsecure response validation collated into one block.
4931 - remove warning about const cast of cfgfile name.
4932 - outgoing-interfaces can be different from service interfaces.
4933 - ldns-src configure is done during unbound configure and
4934 ldns-src make is done during unbound make, and so inherits the
4935 make arguments from the unbound make invocation.
4936 - nicer error when libevent problem causes instant exit on signal.
4937 - read root hints from a root hint file (like BIND does).
4939 18 October 2007: Wouter
4940 - addresses are logged with errors.
4941 - fixup testcode fake event to remove pending before callback
4942 since the callback may create new pending items.
4943 - tests updated because retries are now in iterator module.
4944 - ldns-testpkts code is checked for differences between unbound
4945 and ldns by makedist.sh.
4946 - ldns trunk from today added in svn repo for fallback in case
4947 no ldns is installed on the system.
4948 make download_ldns refreshes the tarball with ldns svn trunk.
4949 - ldns-src.tar.gz is used if no ldns is found on the system, and
4950 statically linked into unbound.
4951 - start of regional allocator code.
4952 - regional uses less memory and variables, simplified code.
4953 - remove of region-allocator.
4954 - alloc cache keeps a cache of recently released regional blocks,
4956 - make unit test cleanly free memory.
4958 17 October 2007: Wouter
4959 - fixup another cycle detect and ns-addr timeout resolution bug.
4960 This time by refusing delegations from the cache without addresses
4961 when resolving a mandatory-glue nameserver-address for that zone.
4962 We're going to have to ask a TLD server anyway; might as well be
4963 the TLD server for this name. And this resolves a lot of cases where
4964 the other nameserver names lead to cycles or are not available.
4965 - changed random generator from random(3) clone to arc4random wrapped
4966 for thread safety. The random generator is initialised with
4967 entropy from the system.
4968 - fix crash where failure to prime DNSKEY tried to print null pointer
4970 - removed some debug prints, only verb_algo (4) enables them.
4971 - fixup test; new random generator took new paths; such as one
4972 where no scripted answer was available.
4973 - mark insecure RRs as insecure.
4974 - fixup removal of nonsecure items from the additional.
4975 - reduced timeout values to more realistic, 376 msec (262 msec has
4976 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
4977 - server selection failover to next server after timeout (376 msec).
4979 16 October 2007: Wouter
4980 - no malloc in log_hex.
4981 - assertions around system calls.
4982 - protect against gethostname without ending zero.
4983 - ntop output is null terminated by unbound.
4984 - pidfile content null termination
4985 - various snprintf use sizeof(stringbuf) instead of fixed constant.
4986 - changed loopdetect % 8 with & 0x7 since % can become negative for
4987 weird negative input and particular interpretation of integer math.
4988 - dname_pkt_copy checks length of result, to protect result buffers.
4989 prints an error, this should not happen. Bad strings should have
4990 been rejected earlier in the program.
4991 - remove a size_t underflow from msgreply size func.
4993 15 October 2007: Wouter
4995 - fix IP6 TCP, wrong definition check. With test package.
4996 - fixup the fact that the query section was not compressed to,
4997 the code was there but was called by value instead of by reference.
4998 And test for the case, uses xxd and nc.
4999 - more portable ip6 check for sockaddr types.
5001 8 October 2007: Wouter
5002 - --disable-rpath option in configure for 64bit systems with
5003 several dynamic lib dirs.
5005 7 October 2007: Wouter
5006 - fixup tests for no AD bit in non-DO queries.
5007 - test that makes sure AD bit is not set on non-DO query.
5009 6 October 2007: Wouter
5010 - removed logfile open early. It did not have the proper permissions;
5011 it was opened as root instead of the user. And we cannot change user
5012 id yet, since chroot and bind ports need to be done.
5013 - callback checks for event callbacks done from mini_event. Because
5014 of deletions cannot do this from netevent. This means when using
5015 libevent the protection does not work on event-callbacks.
5016 - fixup too small reply (did not zero counts).
5017 - fixup reply no longer AD bit when query without DO bit.
5019 5 October 2007: Wouter
5020 - function pointer whitelist.
5022 4 October 2007: Wouter
5023 - overwrite sensitive random seed value after use.
5024 - switch to logfile very soon if not -d (console attached).
5025 - error messages do not reveal the trustanchor contents.
5026 - start work on function pointer whitelists.
5028 3 October 2007: Wouter
5029 - fix for multiple empty nonterminals, after multiple DSes in the
5031 - mesh checks if modules are looping, and stops them.
5032 - refetch with CNAMEd nameserver address regression test added.
5033 - fixup line count bug in testcode, so testbound prints correct line
5034 number with parse errors.
5035 - unit test for multiple ENT case.
5036 - fix for cname out of validated unsec zone.
5037 - fixup nasty id=0 reuse. Also added assertions to detect its
5038 return (the assertion catches in the existing test cases).
5040 1 October 2007: Wouter
5041 - skip F77, CXX, objC tests in configure step.
5042 - fixup crash in refetch glue after a CNAME.
5043 and protection against similar failures (with error print).
5045 28 September 2007: Wouter
5046 - test case for unbound-checkconf, fixed so it also checks the
5047 interface: statements.
5049 26 September 2007: Wouter
5050 - SIGHUP will reopen the log file.
5051 - Option to log to syslog.
5052 - please lint, fixup tests (that went to syslog on open, oops).
5053 - config check program.
5055 25 September 2007: Wouter
5056 - tests for NSEC3. Fixup bitmap checks for NSEC3.
5057 - positive ANY response needs to check if wildcard expansion, and
5058 check that original data did not exist.
5059 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
5060 delegation, for abuse of child zone apex nsec3.
5061 - create 0.5 release tag.
5063 24 September 2007: Wouter
5064 - do not make test programs by default.
5065 - But 'make test' will perform all of the tests.
5066 - Advertise builtin select libevent alternative when no libevent
5068 - signit can generate NSEC3 hashes, for generating tests.
5069 - multiple nsec3 parameters in message test.
5070 - too high nsec3 iterations becomes insecure test.
5072 21 September 2007: Wouter
5073 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
5074 - fixup testcode lock safety (port FreeBSD).
5075 - removes subscript has type char warnings (port Solaris 9).
5076 - fixup of field with format type to int (port MacOS/X intel).
5077 - added test for infinite loop case in nonRD answer validation.
5078 It was a more general problem, but hard to reproduce. When an
5079 unsigned rrset is being validated and the key fetched, the DS
5080 sequence is followed, but if the final name has no DS, then no
5081 proof is possible - the signature has been stripped off.
5083 20 September 2007: Wouter
5084 - fixup and test for NSEC wildcard with empty nonterminals.
5085 - makedist.sh fixup for svn info.
5086 - acl features request in plan.
5087 - improved DS empty nonterminal handling.
5088 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
5089 proof anyway, which succeeds in ANS failure case.
5090 - striplab protection in case it becomes -1.
5091 - plans for static and blacklist config.
5093 19 September 2007: Wouter
5094 - comments about non-packed usage.
5095 - plan for overload support in 0.6.
5096 - added testbound tests for a failed resolution from the logs
5097 and for failed prime when missing glue.
5098 - fixup so useless delegation points are not returned from the
5099 cache. Also the safety belt is used if priming fails to complete.
5100 - fixup NSEC rdata not to be lowercased, bind compat.
5102 18 September 2007: Wouter
5103 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
5104 - validator prints subtype classification for debug.
5106 17 September 2007: Wouter
5107 - NSEC3 hash cache unit test.
5108 - validator nsec3 nameerror test.
5110 14 September 2007: Wouter
5111 - nsec3 nodata proof, nods proof, wildcard proof.
5112 - nsec3 support for cname chain ending in noerror or nodata.
5113 - validator calls nsec3 proof routines if no NSECs prove anything.
5114 - fixup iterator bug where it stored the answer to a cname under
5115 the wrong qname into the cache. When prepending the cnames, the
5116 qname has to be reset to the original qname.
5118 13 September 2007: Wouter
5119 - nsec3 find matching and covering, ce proof, prove namerror msg.
5121 12 September 2007: Wouter
5122 - fixup of manual page warnings, like for NSD bugreport.
5123 - nsec3 work, config, max iterations, filter, and hash cache.
5125 6 September 2007: Wouter
5126 - fixup to find libevent on mac port install.
5127 - fixup size_t vs unsigned portability in validator/sigcrypt.
5128 - please compiler on different platforms, for unreachable code.
5130 - pthread_rwlock type is optional, in case of old pthread libs.
5132 5 September 2007: Wouter
5133 - cname, name error validator tests.
5134 - logging of qtype ANY works.
5135 - ANY type answers get RRSIG in answer section of replies (but not
5136 in other sections, unless DO bit is on).
5137 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
5138 - DS and noDS referral validation test.
5139 - if you configure many trust anchors, parent trust anchors can
5140 securely deny existence of child trust anchors, if validated.
5141 - not all *.name NSECs are present because a wildcard was matched,
5142 and *.name NSECs can prove nodata for empty nonterminals.
5143 Also, for wildcard name NSECs, check they are not from the parent
5144 zone (for wildcarded zone cuts), and check absence of CNAME bit,
5146 - configure option for memory allocation debugging.
5147 - port configure option for memory allocation to solaris10.
5149 4 September 2007: Wouter
5150 - fixup of Leakage warning when serviced queries processed multiple
5151 callbacks for the same query from the same server.
5152 - testbound removes config file from /tmp on failed exit.
5153 - fixup for referral cleanup of the additional section.
5154 - tests for cname, referral validation.
5155 - neater testbound tpkg output.
5156 - DNAMEs no longer match their apex when synthesized from the cache.
5157 - find correct signer name for DNAME responses.
5158 - wildcarded DNAME test and fixup code to detect.
5159 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
5160 So that wildcarded CNAMEs get their NSEC with them to the answer.
5161 - test for a CNAME to a DNAME to a CNAME to an answer, all from
5162 different domains, for key fetching and signature checking of
5165 3 September 2007: Wouter
5166 - Fixed error in iterator that would cause assertion failure in
5167 validator. CNAME to a NXDOMAIN response was collated into a response
5168 with both a CNAME and the NXDOMAIN rcode. Added a test that the
5169 rcode is changed to NOERROR (because of the CNAME).
5170 - timeout on tcp does not lead to spurious leakage detect.
5171 - account memory for name of lame zones, so that memory leakages does
5172 not show lame cache growth as a leakage growth.
5173 - config setting for lameness cache expressed in bytes, instead of
5175 - tool too summarize allocations per code line.
5177 31 August 2007: Wouter
5178 - can read bind trusted-keys { ... }; files, in a compatibility mode.
5179 - iterator should not detach target queries that it still could need.
5180 the protection against multiple outstanding queries is moved to a
5181 current_query num check.
5182 - validator nodata, positive, referral tests.
5183 - dname print can print '*' wildcard.
5185 30 August 2007: Wouter
5186 - fixup override date config option.
5187 - config options to control memory usage.
5188 - caught bad free of un-alloced data in worker_send error case.
5189 - memory accounting for key cache (trust anchors and temporary cache).
5190 - memory accounting fixup for outside network tcp pending waits.
5191 - memory accounting fixup for outside network tcp callbacks.
5192 - memory accounting for iterator fixed storage.
5193 - key cache size and slabs config options.
5194 - lib crypto cleanups at exit.
5196 29 August 2007: Wouter
5197 - test tool to sign rrsets for testing validator with.
5198 - added RSA and DSA test keys, public and private pairs, 512 bits.
5199 - default configuration is with validation enabled.
5200 Only a trust-anchor needs to be configured for DNSSEC to work.
5201 - do not convert to DER for DSA signature verification.
5202 - validator replay test file, for a DS to DNSKEY DSA key prime and
5205 28 August 2007: Wouter
5206 - removed double use for udp buffers, that could fail,
5207 instead performs a malloc to do the backup.
5208 - validator validates referral messages, by validating all the rrsets
5209 and stores the rrsets in the cache. Further referral (nonRD queries)
5210 replies are made from the rrset cache directly. Unless unchecked
5211 rrsets are encountered, there are then validated.
5212 - enforce that signing is done by a parent domain (or same domain).
5213 - adjust TTL downwards if rrset TTL bigger than signature allows.
5214 - permissive mode feature, sets AD bit for secure, but bogus does
5215 not give servfail (bogus is changed into indeterminate).
5216 - optimization of rrset verification. rr canonical sorting is reused,
5217 for the same rrset. canonical rrset image in buffer is reused for
5219 - if the rrset is too big (64k exactly + large owner name) the
5220 canonicalization routine will fail if it does not fit in buffer.
5221 - faster verification for large sigsets.
5222 - verb_detail mode reports validation failures, but not the entire
5223 algorithm for validation. Key prime failures are reported as
5226 27 August 2007: Wouter
5227 - do not garble the edns if a cache answer fails.
5228 - answer norecursive from cache if possible.
5229 - honor clean_additional setting when returning secure non-recursive
5231 - do not store referral in msg cache for nonRD queries.
5232 - store verification status in the rrset cache to speed up future
5234 - mark rrsets indeterminate and insecure if they are found to be so.
5235 and store this in the cache.
5237 24 August 2007: Wouter
5238 - message is bogus if unsecure authority rrsets are present.
5239 - val-clean-additional option, so you can turn it off.
5240 - move rrset verification out of the specific proof types into one
5241 routine. This makes the proof routines prettier.
5242 - fixup cname handling in validator, cname-to-positive and cname-to-
5244 - Do not synthesize DNSKEY and DS responses from the rrset cache if
5245 the rrset is from the additional section. Signatures may have
5246 fallen off the packet, and cause validation failure.
5247 - more verbose signature date errors (with the date attached).
5248 - increased default infrastructure cache size. It is important for
5249 performance, and 1000 entries are only 212k (or a 400 k total cache
5250 size). To 10000 entries (for 2M entries, 4M cache size).
5252 23 August 2007: Wouter
5253 - CNAME handling - move needs_validation to before val_new().
5254 val_new() setups the chase-reply to be an edited copy of the msg.
5255 new classification, and find signer can find for it.
5256 removal of unsigned crap from additional, and query restart for
5258 - refuse to follow wildcarded DNAMEs when validating.
5259 But you can query for qtype ANY, or qtype DNAME and validate that.
5261 22 August 2007: Wouter
5263 - review - use val_error().
5265 21 August 2007: Wouter
5266 - ANY response validation.
5267 - store security status in cache.
5268 - check cache security status and either send the query to be
5269 validated, return the query to client, or send servfail to client.
5270 Sets AD bit on validated replies.
5271 - do not examine security status on an error reply in mesh_done.
5272 - construct DS, DNSKEY messages from rrset cache.
5273 - manual page entry for override-date.
5275 20 August 2007: Wouter
5276 - validate and positive validation, positive wildcard NSEC validation.
5277 - nodata validation, nxdomain validation.
5279 18 August 2007: Wouter
5280 - process DNSKEY response in FINDKEY state.
5282 17 August 2007: Wouter
5283 - work on DS2KE routine.
5284 - val_nsec.c for validator NSEC proofs.
5285 - unit test for NSEC bitmap reading.
5286 - dname iswild and canonical_compare with unit tests.
5288 16 August 2007: Wouter
5290 - latest release libevent 1.3c and 1.3d have threading fixed.
5291 - key entry fixup data pointer and ttl absolute.
5292 - This makes a key-prime succeed in validator, with DS or DNSKEY as
5294 - fixup canonical compare byfield routine, fix bug and also neater.
5295 - fixed iterator response type classification for queries of type
5297 dig ANY gives sometimes NS rrset in AN and NS section, and parser
5298 removes the NS section duplicate. dig NS gives sometimes the NS
5299 in the answer section, as referral.
5300 - validator FINDKEY state.
5302 15 August 2007: Wouter
5303 - crypto calls to verify signatures.
5304 - unit test for rrsig verification.
5306 14 August 2007: Wouter
5307 - default outgoing ports changed to avoid port 2049 by default.
5308 This port is widely blocked by firewalls.
5309 - count infra lameness cache in memory size.
5310 - accounting of memory improved
5311 - outbound entries are allocated in the query region they are for.
5312 - extensive debugging for memory allocations.
5313 - --enable-lock-checks can be used to enable lock checking.
5314 - protect undefs in config.h from autoheaders ministrations.
5315 - print all received udp packets. log hex will print on multiple
5317 - fixed error in parser with backwards rrsig references.
5318 - mark cycle targets for iterator did not have CD flag so failed
5321 13 August 2007: Wouter
5322 - fixup makefile, if lexer is missing give nice error and do not
5323 mess up the dependencies.
5324 - canonical compare routine updated.
5325 - canonical hinfo compare.
5326 - printout list of the queries that the mesh is working on.
5328 10 August 2007: Wouter
5329 - malloc and free overrides that track total allocation and frees.
5330 for memory debugging.
5331 - work on canonical sort.
5333 9 August 2007: Wouter
5334 - canonicalization, signature checks
5335 - dname signature label count and unit test.
5336 - added debug heap size print to memory printout.
5337 - typo fixup in worker.c
5338 - -R needed on solaris.
5339 - validator override option for date check testing.
5341 8 August 2007: Wouter
5342 - ldns _raw routines created (in ldns trunk).
5343 - sigcrypt DS digest routines
5344 - val_utils uses sigcrypt to perform signature cryptography.
5345 - sigcrypt keyset processing
5347 7 August 2007: Wouter
5348 - security status type.
5349 - security status is copied when rdata is equal for rrsets.
5350 - rrset id is updated to invalidate all the message cache entries
5351 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
5353 - val_sigcrypt file for validator signature checks.
5355 6 August 2007: Wouter
5356 - key cache for validator.
5357 - moved isroot and dellabel to own dname routines, with unit test.
5359 3 August 2007: Wouter
5361 - scrubber check section of lame NS set.
5362 - trust anchors can be in config file or read from zone file,
5363 DS and DNSKEY entries.
5364 - unit test trust anchor storage.
5365 - trust anchors converted to packed rrsets.
5366 - key entry definition.
5368 2 August 2007: Wouter
5369 - configure change for latest libevent trunk version (needs -lrt).
5370 - query_done and walk_supers are moved out of module interface.
5371 - fixup delegation point duplicates.
5372 - fixup iterator scrubber; lame NS set is let through the scrubber
5373 so that the classification is lame.
5374 - validator module exists, and does nothing but pass through,
5375 with calling of next module and return.
5378 1 August 2007: Wouter
5379 - set version to 0.5
5380 - module work for module to module interconnections.
5381 - config of modules.
5382 - detect cycle takes flags.
5384 31 July 2007: Wouter
5388 30 July 2007: Wouter
5389 - changed random state init, so that sequential process IDs are not
5390 cancelled out by sequential thread-ids in the random number seed.
5391 - the fwd_three test, which sends three queries to unbound, and
5392 unbound is kept waiting by ldns-testns for 3 seconds, failed
5393 because the retry timeout for default by unbound is 3 seconds too,
5394 it would hit that timeout and fail the test. Changed so that unbound
5395 is kept waiting for 2 seconds instead.
5397 27 July 2007: Wouter
5398 - removed useless -C debug option. It did not work.
5399 - text edit of documentation.
5400 - added doc/CREDITS file, referred to by the manpages.
5403 26 July 2007: Wouter
5404 - cycle detection, for query state dependencies. Will attempt to
5405 circumvent the cycle, but if no other targets available fails.
5406 - unit test for AXFR, IXFR response.
5407 - test for cycle detection.
5409 25 July 2007: Wouter
5410 - testbound read ADDRESS and check it.
5411 - test for version.bind and friends.
5412 - test for iterator chaining through several referrals.
5413 - test and fixup for refetch for glue. Refetch fails if glue
5414 is still not provided.
5416 24 July 2007: Wouter
5417 - Example section in config manual.
5418 - Addr stored for range and moment in replay.
5420 20 July 2007: Wouter
5421 - Check CNAME chain before returning cache entry with CNAMEs.
5422 - Option harden-glue, default is on. It will discard out of zone
5423 data. If disabled, performance is faster, but spoofing attempts
5424 become a possibility. Note that still normalize scrubbing is done,
5425 and that the potentially spoofed data is used for infrastructure
5426 and not returned to the client.
5427 - if glue times out, refetch by asking parent of delegation again.
5428 Much like asking for DS at the parent side.
5429 - TODO items from forgery-resilience draft.
5430 and on memory handling improvements.
5431 - renamed module_event_timeout to module_event_noreply.
5432 - memory reporting code; reports on memory usage after handling
5433 a network packet (not on cache replies).
5435 19 July 2007: Wouter
5436 - shuffle NS selection when getting nameserver target addresses.
5437 - fixup of deadlock warnings, yield cpu in checklock code so that
5438 freebsd scheduler selects correct process to run.
5439 - added identity and version config options and replies.
5440 - store cname messages complete answers.
5442 18 July 2007: Wouter
5443 - do not query addresses, 127.0.0.1, and ::1 by default.
5445 17 July 2007: Wouter
5446 - forward zone options in config file.
5447 - forward per zone in iterator. takes precedence over stubs.
5448 - fixup commithooks.
5449 - removed forward-to and forward-to-port features, subsumed by
5451 - fix parser to handle absent server: clause.
5452 - change untrusted rrset test to account for scrubber that is now
5453 applied during the test (which removes the poison, by the way).
5454 - feature, addresses can be specified with @portnumber, like nsd.conf.
5455 - test config files changed over to new forwarder syntax.
5457 27 June 2007: Wouter
5458 - delete of mesh does a postorder traverse of the tree.
5459 - found and fixed a memory leak. For TTL=0 messages, that would
5460 not be cached, instead the msg-replyinfo structure was leaked.
5461 - changed server selection so it will filter out hosts that are
5462 unresponsive. This is defined as a host with the maximum rto value.
5463 This means that unbound tried the host for retries up to 120 secs.
5464 The rto value will time out after host-ttl seconds from the cache.
5465 This keeps such unresolvable queries from taking up resources.
5466 - utility for keeping histogram.
5468 26 June 2007: Wouter
5469 - mesh is called by worker, and iterator uses it.
5470 This removes the hierarchical code.
5471 QueryTargets state and Finished state are merged for iterator.
5472 - forwarder mode no longer sets AA bit on first reply.
5473 - rcode in walk_supers is not needed.
5475 25 June 2007: Wouter
5477 - error encode routine for ease.
5479 22 June 2007: Wouter
5480 - removed unused _node iterator value from rbtree_t. Takes up space.
5481 - iterator can handle querytargets state without a delegation point
5482 set, so that a priming(stub) subquery error can be handled.
5483 - iterator stores if it is priming or not.
5484 - log_query_info() neater logging.
5485 - changed iterator so that it does not alter module_qstate.qinfo
5486 but keeps a chase query info. Also query_flags are not altered,
5487 the iterator uses chase_flags.
5488 - fixup crash in case no ports for the family exist.
5490 21 June 2007: Wouter
5491 - Fixup secondary buffer in case of error callback.
5492 - cleanup slumber list of runnable states.

5503 - set num target queries to 0 when you move them to slumber list.
5504 - typo in check caused subquery errors to be ignored, fixed.
5505 - make lint happy about rlim_t.
5506 - freeup of modules after freeup of module-states.
5507 - duplicate replies work, this uses secondary udp buffer in outnet.
5509 19 June 2007: Wouter
5510 - nicer layout in stats.c, review 0.3 change.
5511 - spelling improvement, review 0.3 change.

5525 - another offbyone in targetcounter. Also in Java prototype by the way.
5527 15 June 2007: Wouter
5528 - if a query asks to be notified of the same serviced query result
5529 multiple times, this will succeed. Only one callback will happen;
5530 multiple outbound-list entries result (but the double cleanup of it
5532 - when iterator moves on due to CNAME or referral, it will remove
5533 the subqueries (for other targets). These are put on the slumber
5535 - state module wait subq is OK with no new subqs, an old one may have
5536 stopped, with an error, and it is still waiting for other ones.
5537 - if a query loops, halt entire query (easy way to clean up properly).
5539 14 June 2007: Wouter
5540 - num query targets was > 0 , not >= 0 compared, so that fetch
5541 policy of 0 did nothing.
5543 13 June 2007: Wouter
5544 - debug option: configure --enable-static-exe for compile where
5545 ldns and libevent are linked statically. Default is off.

5559 11 June 2007: Wouter
5560 - replies on TCP queries have the address field set in replyinfo,
5561 for serviced queries, because the initiator does not know that
5562 a TCP fallback has occured.
5563 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
5564 if qtype directly queries for the type (and then only show that
5565 'unknown type' in the answer section).
5566 - fixed message parsing where rrsigs on their own would be put
5567 in the signature list over the rrsig type.

5595 - debug routine to print dns_msg as handled by iterator.
5596 - memleak in config file stubs fixup.
5597 - more small bugs, in scrubber, query compare no ID for lookup,
5598 in dname validation for NS targets.
5599 - sets entry.key for new special allocs.
5600 - lognametypeclass can display unknown types and classes.
5603 - random selection of equally preferred nameserver targets.
5604 - reply info copy routine. Reuses existing code.
5605 - cache lameness in response handling.
5606 - do not touch qstate after worker_process_query because it may have

5608 - Prime response state.
5609 - Process target response state.
5610 - some memcmp changed to dname_compare for case preservation.

5623 - server selection, based on RTT. ip6 is filtered out if not available,
5624 and lameness is checked too.
5625 - delegation point copy routine.
5628 - removed FLAG_CD from message and rrset caches. This was useful for
5629 an agnostic forwarder, but not for a sophisticated (trust value per
5630 rrset enabled) cache.
5631 - iterator response typing.
5632 - iterator cname handle.
5633 - iterator prime start.
5635 - processInitRequest and processInitRequest2.

5650 rrset cache from module environment.
5651 - packed rrset key has type and class as easily accessible struct
5652 members. They are still kept in network format for fast msg encode.
5653 - dns cache find_delegation routine.

5762 not fit, and will leave out (whole)rrsets from additional if needed.
5765 - decompress query section, extremely lenient acceptance.
5766 But only for answers from other servers, not for plain queries.
5767 - compression and decompression test cases.
5769 - example.conf interface: line is changed from 127.0.0.1 which leads
5770 to problems if used (restricting communication to the localhost),
5771 to a documentation and test address.

5864 3 April 2007: Wouter
5865 - detect sign of msghdr.msg_iovlen so that the cast to that type
5866 in netevent (which is there to please lint) can be correct.

5951 9 March 2007: Wouter
5952 - added rwlock writelock checking.
5953 So it will keep track of the writelock, and readlocks are enforced
5954 to not change protected memory areas.
5955 - log_hex function to dump hex strings to the logfile.
5956 - checklocks zeroes its destroyed lock after checking memory areas.
5957 - unit test for alloc.
5958 - identifier for union in checklocks to please older compilers.
5961 8 March 2007: Wouter
5962 - Reviewed checklock code.
5964 7 March 2007: Wouter
5965 - created a wrapper around thread calls that performs some basic
5966 checking for data race and deadlock, and basic performance
5967 contention measurement.
5969 6 March 2007: Wouter
5970 - Testbed works with threading (different machines, different options).
5971 - alloc work, does the special type.
5973 2 March 2007: Wouter
5974 - do not compile fork funcs unless needed. Otherwise will give
5975 type errors as their typedefs have not been enabled.
5976 - log shows thread numbers much more nicely (and portably).
5977 - even on systems with nonthreadsafe libevent signal handling,
5978 unbound will exit if given a signal.

5991 Thread_join is replaced with waitpid.
5992 - During reloads the daemon will temporarily handle signals,
5993 so that they do not result in problems.
5994 - Also randomize the outgoing port range for tests.
5995 - If query list is full, will stop selecting listening ports for read.
5996 This makes all threads service incoming requests, instead of one.
5997 No memory is leaking during reloads, service of queries, etc.
5998 - test that uses ldns-testns -f to test threading. Have to answer
5999 three queries at the same time.
6000 - with verbose=0 operates quietly.

6007 - don't open pipes for #0, doesn't need it.
6008 - listens to SIGTERM, SIGQUIT, SIGINT (all quit) and SIGHUP (reload).
6010 23 February 2007: Wouter
6011 - Can do reloads on sigHUP. Everything is stopped, and freed,
6012 except the listening ports. Then the config file is reread.
6013 And everything is started again (and listening ports if needed).
6014 - Ports for queries are shared.
6015 - config file added interface:, chroot: and username:.
6016 - config file: directory, logfile, pidfile. And they work too.
