176 load a readonly auto-trust-anchor-file with trust-anchor-file.
177 The file has to be writable to notice the trust anchor change,
178 without it, a trust anchor change will be unnoticed and the system
179 will then become inoperable.

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

605 Generate unbound-control-setup.sh at build time so it respects
606 prefix and sysconfdir from the configure script. Also fix the
607 umask to match the comment, and the comment to match the umask.
608 Add const and static where needed. Use unions instead of
609 playing pointer poker. Move declarations that are needed in
610 multiple source files into a shared header. Move sldns_bgetc()
611 from parse.c to buffer.c where it belongs. Introduce a new
612 header file, worker.h, which declares the callbacks that
613 all workers must define. Remove those declarations from
614 libworker.h. Include the correct headers in the correct places.
615 Fix a few dummy callbacks that don't match their prototype.
616 Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK.
617 Remove a useless printf which breaks reproducible builds.
618 Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
619 no longer used. Add unbound-control-setup.sh to the list of
620 generated files. The prototype for libworker_event_done_cb()
621 needs to be moved from libunbound/libworker.h to

658 29 April 2014: Wouter
659 - iana portlist updated.
660 - Add unbound-control flush_negative that flushed nxdomains, nodata,
661 and errors from the cache. For dnssec-trigger and NetworkManager,
662 fixes cases where network changes have localdata that was already
663 negatively cached from the previous network.
665 23 April 2014: Wouter
666 - Patch from Jeremie Courreges-Anglas to use arc4random_uniform
667 if available on the OS, it gets entropy from the OS.

686 (for NetworkManager integration.)
687 - Fix #554: use unsigned long to print 64bit statistics counters on
689 - Fix #558: failed prefetch lookup does not remove cached response

691 - Fix #545: improved logging, the ip address of the error is printed
692 on the same log-line as the error.
695 - Fix #574: make test fails on Ubuntu 14.04. Disabled remote-control
696 in testbound scripts.
697 - iana portlist updated.

725 21 February 2014: Wouter
726 - iana portlist updated.
728 20 February 2014: Matthijs
729 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
730 received. This is okay according 4035, but not after revising
731 existence in 4592. NSEC empty non-terminals exist and thus the
732 RCODE should have been NOERROR. If this occurs, and the RRsets
733 are secure, we set the RCODE to NOERROR and the security status
734 of the reponse is also considered secure.
736 14 February 2014: Wouter

769 - fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
772 30 January 2014: Wouter
773 - delay-close does not act if there are udp-wait queries, so that
774 it does not make a socketdrain DoS easier.
776 28 January 2014: Wouter
777 - iana portlist updated.
778 - iana portlist test updated so it does not touch the source
779 if there are no changes.
780 - delay-close: msec option that delays closing ports for which
781 the UDP reply has timed out. Keeps the port open, only accepts
782 the correct reply. This correct reply is not used, but the port
783 is open so that no port-denied ICMPs are generated.
785 27 January 2014: Wouter
786 - reuseport is attempted, then fallback to without on failure.
788 24 January 2014: Wouter

790 - iana portlist updated.
791 - unbound-event.h is installed if you configure --enable-event-api.
792 - speed up unbound (reports say it could be up to 10%), by reducing
793 lock contention on localzones.lock. It is changed to an rwlock.
794 - so-reuseport: yesno option to distribute queries evenly over
795 threads on Linux (Thanks Robert Edmonds).
798 21 January 2014: Wouter
799 - Fix #547: no trustanchor written if filesystem full, fclose checked.
801 17 January 2014: Wouter

833 is called by libunbound in the mesh attach.
834 - Accept ip-address: as an alternative for interface: for
835 consistency with nsd.conf syntax.
838 - Patch from Neel Goyal to fix callback in libunbound.
841 - if configured --with-libunbound-only fix make install.
844 - Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
845 more specific interface port 53 can be used at the same time, and
846 one of the daemons is unbound.
847 - iana portlist update.
848 - separate ldns into core ldns inside ldns/ subdirectory. No more
849 --with-ldns is needed and unbound does not rely on libldns.
850 - portability fixes for new USE_SLDNS ldns subdir codebase.
853 - Patch from Neel Goyal: Add an API call to set an event base on an
854 existing ub_ctx. This basically just destroys the current worker and
855 sets the event base to the current. And fix a deadlock in
856 ub_resolve_event – the cfglock is held when libworker_create is
857 called. This ends up trying to acquire the lock again in
858 context_obtain_alloc in the call chain.
859 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
862 - unbound-event.h is installed if configured --with-libevent. It
863 contains low-level library calls, that use libevent's event_base
864 and an ldns_buffer for the wire return packet to perform async
865 resolution in the client's eventloop.

936 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
937 immediately. The others are mostly useful for libunbound users.
940 - get_option, set_option, unbound-checkconf -o and libunbound
941 getoption and setoption support cache-min-ttl and cache-max-ttl.
944 - Fix#501: forward-first does not recurse, when forward name is ".".
945 - iana portlist update.
946 - Max include depth is unlimited.
949 - Update acx_pthreads.m4 to ax_pthreads.4 (2013-03-29), and apply
950 patch to it to not fail when -Werror is also specified, from the
952 - iana portlist update.

1267 19 June 2012: Wouter
1268 - --with-libunbound-only build option, only builds the library and
1269 not the daemon and other tools.
1271 18 June 2012: Wouter
1274 15 June 2012: Wouter

1335 - fix bug #442: Fix that Makefile depends on pythonmod headers
1336 even using --without-pythonmodule.
1338 22 March 2012: Wouter
1339 - contrib/validation-reporter follows rotated log file (patch from
1342 21 March 2012: Wouter
1343 - new approach to NS fetches for DS lookup that works with
1344 cornercases, and is more robust and considers forwarders.
1346 19 March 2012: Wouter
1347 - iana portlist updated.
1348 - fix to locate nameservers for DS lookup with NS fetches.
1350 16 March 2012: Wouter
1351 - Patch for access to full DNS packet data in unbound python module
1354 9 March 2012: Wouter
1355 - Applied line-buffer patch from Augie Schwer to validation.reporter.sh.
1357 2 March 2012: Wouter
1358 - flush_infra cleans timeouted servers from the cache too.
1359 - removed warning from --enable-ecdsa.
1361 1 March 2012: Wouter
1362 - forward-first option. Tries without forward if a query fails.
1363 Also stub-first option that is similar.
1365 28 February 2012: Wouter
1366 - Fix from code review, if EINPROGRESS not defined chain if statement
1369 27 February 2012: Wouter
1370 - Fix bug#434: on windows check registry for config file location
1371 for unbound-control.exe, and unbound-checkconf.exe.
1373 23 February 2012: Wouter
1374 - Fix to squelch 'network unreachable' errors from tcp connect in
1375 logs, high verbosity will show them.
1377 16 February 2012: Wouter
1378 - iter_hints is now thread-owned in module env, and thus threadsafe.
1379 - Fix prefetch and sticky NS, now the prefetch works. It picks
1380 nameservers that 'would be valid in the future', and if this makes
1381 the NS timeout, it updates that NS by asking delegation from the
1382 parent again. If child NS has longer TTL, that TTL does not get
1383 refreshed from the lookup to the child nameserver.
1385 15 February 2012: Wouter
1386 - Fix forward-zone memory, uses malloc and frees original root dp.
1387 - iter hints (stubs) uses malloc inside for more dynamicity.
1388 - unbound-control forward_add, forward_remove, stub_add, stub_remove
1389 can modify stubs and forwards for running unbound (on mobile computer)
1390 they can also add and remove domain-insecure for the zone.
1392 14 February 2012: Wouter
1393 - Fix sticky NS (ghost domain problem) if prefetch is yes.
1394 - iter forwards uses malloc inside for more dynamicity.
1396 13 February 2012: Wouter
1397 - RT#2955. Fix for cygwin compilation.
1398 - iana portlist updated.
1400 10 February 2012: Wouter
1401 - Slightly smaller critical region in one case in infra cache.
1402 - Fix timeouts to keep track of query type, A, AAAA and other, if
1403 another has caused timeout blacklist, different type can still probe.
1404 - unit test fix for nomem_cnametopos.rpl race condition.
1406 9 February 2012: Wouter
1407 - Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
1409 8 February 2012: Wouter
1410 - implement draft-ietf-dnsext-ecdsa-04; which is in IETF LC; This
1411 implementation is experimental at this time and not recommended
1412 for use on the public internet (the protocol numbers have not
1413 been assigned). Needs recent ldns with --enable-ecdsa.
1414 - fix memory leak in errorcase for DSA signatures.
1415 - iana portlist updated.
1416 - workaround for openssl 0.9.8 ecdsa sha2 and evp problem.
1418 3 February 2012: Wouter

1423 - svn trunk is 1.4.17 in development.
1424 - iana portlist updated.
1426 1 February 2012: Wouter
1427 - Fix validation failures (like: validation failure xx: no NSEC3
1428 closest encloser from yy for DS zz. while building chain of trust,
1429 because of a bug in the TTL-fix in 1.4.15, it picked the wrong rdata
1430 for an NSEC3. Now it does not change rdata, and fixes TTL.
1432 30 January 2012: Wouter
1433 - Fix version-number in libtool to be version-info so it produces
1434 libunbound.so.2 like it should.
1436 26 January 2012: Wouter
1437 - Tag 1.4.15 (same as 1.4.15rc1), for 1.4.15 release.
1438 - trunk 1.4.16; includes changes memset testcode, #424 openindiana,
1439 and keyfile write fixup.
1440 - applied patch to support outgoing-interface with ub_ctx_set_option.
1442 23 January 2012: Wouter
1443 - Fix memset in test code.
1445 20 January 2012: Wouter
1446 - Fix bug #424: compile on OpenIndiana OS with gcc 4.6.2.
1448 19 January 2012: Wouter
1449 - Fix to write key files completely to a temporary file, and if that
1450 succeeds, replace the real key file. So failures leave a useful file.
1452 18 January 2012: Wouter
1453 - tag 1.4.15rc1 created
1454 - updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
1456 17 January 2012: Wouter
1457 - Fix bug where canonical_compare of RRSIG did not downcase the
1458 signer-name. This is mostly harmless because RRSIGs do not have
1459 to be sorted in canonical order, usually.
1461 12 January 2012: Wouter
1462 - bug#428: add ub_version() call to libunbound. API version increase,
1463 with (binary) backwards compatibility for the previous version.
1465 10 January 2012: Wouter
1466 - Fix bug #425: unbound reports wrong TTL in reply, it reports a TTL
1467 that would be permissible by the RFCs but it is not the TTL in the
1469 - iana portlist updated.
1470 - uninitialised variable in reprobe for rtt blocked domains fixed.
1471 - lintfix and new flex output.
1473 2 January 2012: Wouter
1474 - Fix to randomize hash function, based on 28c3 congress, reported
1477 24 December 2011: Wouter
1478 - Fix for memory leak (about 20 bytes when a tcp or udp send operation
1479 towards authority servers failed, takes about 50.000 such failures to
1480 leak one Mb, such failures are also usually logged), reported by
1482 - iana portlist updated.
1484 19 December 2011: Wouter
1485 - Fix for VU#209659 CVE-2011-4528: Unbound denial of service
1486 vulnerabilities from nonstandard redirection and denial of existence
1487 http://www.unbound.net/downloads/CVE-2011-4528.txt

1500 - Fix to constrain signer_name to be a parent of the lookupname.
1502 5 December 2011: Wouter
1503 - Fix getaddrinfowithincludes on windows with fedora16 mingw32-gcc.
1504 - Fix warnings with gcc 4.6 in compat/inet_ntop.c.
1505 - Fix warning unused in compat/strptime.c.

1511 30 November 2011: Wouter
1512 - Fix for tcp-upstream and ssl-upstream for if a laptop sleeps, causes
1513 SERVFAILs. Also fixed for UDP (but less likely).
1515 28 November 2011: Wouter
1516 - Fix quartile time estimate, it was too low, (thanks Jan Komissar).
1517 - iana ports updated.
1519 11 November 2011: Wouter
1520 - Makefile compat with SunOS make, BSD make and GNU make.

1538 - documentation for new options: ssl-upstream, ssl-service-key and
1540 - iana portlist updated.
1541 - fix -flto detection on Lion for llvm-gcc.
1543 31 October 2011: Wouter
1544 - dns over ssl support, ssl-service-pem and ssl-service-key files
1545 can be given and then TCP queries are serviced wrapped in SSL.
1547 27 October 2011: Wouter
1548 - lame-ttl and lame-size options no longer exist, it is integrated
1549 with the host info. They are ignored (with verbose warning) if
1550 encountered to keep the config file backwards compatible.
1551 - fix iana-update for changing gzip compression of results.
1552 - fix export-all-symbols on OSX.
1554 26 October 2011: Wouter

1557 This fixes bug #416.
1558 - fix iana_update target for gzipped file on iana site.
1560 24 October 2011: Wouter
1561 - Fix resolve of partners.extranet.microsoft.com with a fix for the
1562 server selection for choosing out of a (particular) list of bad
1564 - Fix make_new_space function so that the incoming query is not
1565 overwritten if a jostled out query causes a waiting query to be
1566 resumed that then fails and sends an error message. (Thanks to
1569 21 October 2011: Wouter
1570 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
1571 option enabled because of memory layout exe vs dll.
1573 19 October 2011: Wouter
1574 - fix unbound-anchor for broken strptime on OSX lion, detected
1576 - Detect if GOST really works, openssl1.0 on OSX fails.
1577 - Implement ipv6%interface notation for scope_id usage.
1579 17 October 2011: Wouter
1580 - better documentation for inform_super (Thanks Yang Zhe).
1582 14 October 2011: Wouter
1583 - Fix for out-of-memory condition in libunbound (thanks
1586 13 October 2011: Wouter
1587 - Fix --enable-allsymbols, it depended on link specifics of the
1588 target platform, or fptr_wlist assertion failures could occur.
1590 12 October 2011: Wouter
1591 - updated contrib/unbound_munin_ to family=auto so that it works with
1592 munin-node-configure automatically (if installed as
1593 /usr/local/share/munin/plugins/unbound_munin_ ).
1595 27 September 2011: Wouter
1596 - unbound.exe -w windows option for start and stop service.
1598 23 September 2011: Wouter
1599 - TCP-upstream calculates tcp-ping so server selection works if there
1602 20 September 2011: Wouter
1603 - Fix classification of NS set in answer section, where there is a
1604 parent-child server, and the answer has the AA flag for dir.slb.com.
1605 Thanks to Amanda Constant from Secure64.
1607 16 September 2011: Wouter
1608 - fix bug #408: accept patch from Steve Snyder that comments out
1609 unused functions in lookup3.c.
1610 - iana portlist updated.
1611 - fix EDNS1480 change memleak and TCP fallback.
1612 - fix various compiler warnings (reported by Paul Wouters).
1613 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
1614 fetch if sentcount > 3, stop query if sentcount > 16. Count is
1615 reset when referral or CNAME happens. This makes unbound better
1616 at managing large NS sets, they are explored when there is continued
1617 interest (in the form of queries).
1619 15 September 2011: Wouter
1621 - trunk contains 1.4.14 in development.
1622 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
1624 12 September 2011: Wouter
1625 - Reverted dns EDNS backoff fix, it did not help and needs
1626 fragmentation fixes instead.
1629 7 September 2011: Wouter
1630 - Fix operation in ipv6 only (do-ip4: no) mode.
1632 6 September 2011: Wouter
1633 - fedora specfile updated.
1635 5 September 2011: Wouter
1638 2 September 2011: Wouter
1639 - iana portlist updated.
1641 26 August 2011: Wouter
1642 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
1643 - Fix validation failures due to EDNS backoff retries, the retry
1644 for fetch of data has want_dnssec because the iter_indicate_dnssec
1645 function returns true when validation failure retry happens, and
1646 then the serviced query code does not fallback to noEDNS, even if
1647 the cache says it has this. This helps for DLV deployment when
1648 the DNSSEC status is not known for sure before the lookup concludes.
1650 24 August 2011: Wouter
1651 - Applied patch from Karel Slany that fixes a memory leak in the
1652 unbound python module, in string conversions.
1654 22 August 2011: Wouter
1655 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
1656 Zhang and Luo Ce). Unbound responds with the RR types that are
1657 available at the name for qtype ANY and validates those RR types.
1658 It does not test for completeness (i.e. with NSEC or NSEC3 query),
1659 and it does not follow the CNAME or DNAME to another name (with
1660 even more data for the already large response).
1661 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
1662 - Documented the options that work with control set_option command.
1663 - tcp-upstream yes/no option (works with set_option) for tunnels.
1665 18 August 2011: Wouter
1666 - fix autoconf call in makedist crosscompile to RC or snapshot.
1668 17 August 2011: Wouter

1671 - iana portlist updated.
1673 10 August 2011: Wouter
1674 - Fix python site-packages path to /usr/lib64.
1675 - updated patch from Tom.
1676 - fix memory and fd leak after out-of-memory condition.
1678 9 August 2011: Wouter
1679 - patch from Tom Hendrikx fixes load of python modules.
1681 8 August 2011: Wouter
1682 - make clean had ldns-src reference, removed.
1684 1 August 2011: Wouter
1685 - Fix autoconf 2.68 warnings
1687 14 July 2011: Wouter
1688 - Unbound implements RFC6303 (since version 1.4.7).
1689 - tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
1690 meantime, those are for 1.4.13).
1691 - iana portlist updated.
1693 13 July 2011: Wouter
1694 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
1696 11 July 2011: Wouter
1697 - Fix wildcard expansion no-data reply under an optout NSEC3 zone is
1698 validated as insecure, reported by Jia Li (lijia@cnnic.cn).
1701 - 1.4.12rc1 tag created.
1704 - version number in example config file.
1705 - fix that --enable-static-exe does not complain about it unknown.
1707 30 June 2011: Wouter
1708 - tag relase 1.4.11, trunk is 1.4.12 development.
1709 - iana portlist updated.
1710 - fix bug#395: id bits of other query may leak out under conditions
1711 - fix replyaddr count wrong after jostled queries, which leads to
1712 eventual starvation where the daemon has no replyaddrs left to use.
1713 - fix comment about rndc port, that referred to the old port number.
1714 - fix that the listening socket is not closed when too many remote
1715 control connections are made at the same time.
1716 - removed ldns-src tarball inside the unbound tarball.
1718 23 June 2011: Wouter
1719 - Changed -flto check to support clang compiler.
1720 - tag 1.4.11rc3 created.
1722 17 June 2011: Wouter
1723 - tag 1.4.11rc1 created.
1724 - remove warning about signed/unsigned from flex (other flex version).
1725 - updated aclocal.m4 and libtool to match.
1726 - tag 1.4.11rc2 created.
1728 16 June 2011: Wouter
1729 - log-queries: yesno option, default is no, prints querylog.
1730 - version is 1.4.11.
1732 14 June 2011: Wouter
1733 - Use -flto compiler flag for link time optimization, if supported.
1734 - iana portlist updated.
1736 12 June 2011: Wouter
1737 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
1739 10 June 2011: Wouter
1740 - unbound-control has version number in the header,
1741 UBCT[version]_space_ is the header sent by the client now.
1742 - Unbound control port number is registered with IANA:
1743 ub-dns-control 8953/tcp unbound dns nameserver control
1744 This is the new default for the control-port config setting.
1745 - statistics-interval prints the number of jostled queries to log.
1748 - Fix Makefile for U in environment, since wrong U is more common than
1749 deansification necessity.
1750 - iana portlist updated.
1751 - updated ldns tarball to 1.6.10rc2 snapshot of today.
1754 - Fix assertion failure when unbound generates an empty error reply
1755 in response to a query, CVE-2011-1922 VU#531342.
1756 - This fix is in tag 1.4.10.
1757 - defense in depth against the above bug, an error is printed to log
1758 instead of an assertion failure.
1761 - bug#386: --enable-allsymbols option links all binaries to libunbound
1762 and reduces install size significantly.
1763 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
1764 - iana portlist updated.
1765 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
1767 14 April 2011: Wouter
1768 - configure created with newer autoconf 2.66.
1770 12 April 2011: Wouter
1771 - bug#378: Fix that configure checks for ldns_get_random presence.
1773 8 April 2011: Wouter
1774 - iana portlist updated.
1775 - queries with CD flag set cause DNSSEC validation, but the answer is
1776 not withheld if it is bogus. Thus, unbound will retry if it is bad
1777 and curb the TTL if it is bad, thus protecting the cache for use by
1778 downstream validators.
1779 - val-override-date: -1 ignores dates entirely, for NTP usage.
1781 29 March 2011: Wouter
1782 - harden-below-nxdomain: changed so that it activates when the
1783 cached nxdomain is dnssec secure. This avoids backwards
1784 incompatibility because those old servers do not have dnssec.
1786 24 March 2011: Wouter
1787 - iana portlist updated.
1791 17 March 2011: Wouter
1792 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
1793 Applied but did not do the --disable-gost.

1803 - give config parse error for multiple names on a stub or forward zone.
1804 - updated ldns tarball to 1.6.9(todays snapshot).
1806 24 February 2011: Wouter
1807 - bug #361: Fix, time.elapsed variable not reset with stats_noreset.
1809 23 February 2011: Wouter

1819 and under the terms of our LICENSE (see that file in the source).
1821 11 February 2011: Wouter
1822 - iana portlist updated.
1823 - tpkg updated with common.sh for common functionality.
1825 7 February 2011: Wouter
1826 - Added regression test for addition of a .net DS to the root, and
1827 cache effects with different TTL for glue and DNSKEY.
1828 - iana portlist updated.
1830 28 January 2011: Wouter
1831 - Fix remove private address does not throw away entire response.
1833 24 January 2011: Wouter
1836 19 January 2011: Wouter
1837 - fix bug#349: no -L/usr for ldns.
1839 18 January 2011: Wouter

1849 server, for type NS the TTL is not increased.
1851 13 January 2011: Wouter
1852 - Fix prefetch so it does not get stuck on old server for moved names.
1854 12 January 2011: Wouter
1855 - iana portlist updated.
1857 11 January 2011: Wouter

1866 - iana portlist updated.
1868 23 December 2010: Wouter
1869 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
1871 21 December 2010: Wouter
1872 - algorithm compromise protection using the algorithms signalled in
1873 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
1874 and thus, if you have multiple algorithms in your trust-anchor-file
1875 then it will now behave different than before. Also, 5011 rollover
1876 for algorithms needs to be double-signature until the old algorithm
1878 It is not an option, because I see no use to turn the security off.
1879 - iana portlist updated.
1881 17 December 2010: Wouter
1882 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
1883 - fix validation in this case: CNAME to nodata for co-hosted opt-in
1884 NSEC3 insecure delegation, was bogus, fixed to be insecure.
1886 16 December 2010: Wouter
1887 - Fix our 'BDS' license (typo reported by Xavier Belanger).
1889 10 December 2010: Wouter

1901 - iana portlist updated.
1903 18 November 2010: Wouter
1904 - harden-below-nxdomain option, default off (because very old
1905 software may be incompatible). We could enable it by default in
1908 17 November 2010: Wouter
1909 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
1910 - make test output nicer.
1912 15 November 2010: Wouter
1913 - silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
1914 - iana portlist updated.
1915 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
1917 9 November 2010: Wouter
1918 - unbound-anchor compiles with openssl 0.9.7.
1920 8 November 2010: Wouter

1932 - Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
1934 2 November 2010: Wouter
1938 1 November 2010: Wouter
1939 - GOST code enabled by default (RFC 5933).
1941 27 October 2010: Wouter
1942 - Fix uninit value in dump_infra print.
1943 - Fix validation failure for parent and child on same server with an
1944 insecure childzone and a CNAME from parent to child.
1945 - Configure detects libev-4.00.
1947 26 October 2010: Wouter
1948 - dump_infra and flush_infra commands for unbound-control.
1949 - no timeout backoff if meanwhile a query succeeded.
1950 - Change of timeout code. No more lost and backoff in blockage.
1951 At 12sec timeout (and at least 2x lost before) one probe per IP
1952 is allowed only. At 120sec, the IP is blocked. After 15min, a
1953 120sec entry has a single retry packet.
1955 25 October 2010: Wouter
1956 - Configure errors if ldns is not found.
1958 22 October 2010: Wouter
1959 - Windows 7 fix for the installer.
1961 21 October 2010: Wouter
1962 - Fix bug where fallback_tcp causes wrong roundtrip and edns
1963 observation to be noted in cache. Fix bug where EDNSprobe halted
1964 exponential backoff if EDNS status unknown.
1965 - new unresponsive host method, exponentially increasing block backoff.
1966 - iana portlist updated.
1968 20 October 2010: Wouter
1969 - interface automatic works for some people with ip6 disabled.
1970 Therefore the error check is removed, so they can use the option.
1972 19 October 2010: Wouter
1973 - Fix for request list growth, if a server has long timeout but the
1974 lost counter is low, then its effective rtt is the one without
1975 exponential backoff applied. Because the backoff is not working.
1976 The lost counter can then increase and the server is blacklisted,
1977 or the lost counter does not increase and the server is working
1980 18 October 2010: Wouter
1981 - iana portlist updated.
1983 13 October 2010: Wouter
1984 - Fix TCP so it uses a random outgoing-interface.
1985 - unbound-anchor handles ADDPEND keystate.
1987 11 October 2010: Wouter
1988 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
1989 the zone has a secure delegation hosted on the same server did not
1990 verify as secure (it was insecure by mistake).
1991 - iana portlist updated.
1992 - ldns tarball updated (for reading cachedumps with bad RR data).
1994 1 October 2010: Wouter

1996 - Fix alloc_reg_release for longer uptime in out of memory conditions.
1998 28 September 2010: Wouter
1999 - unbound-anchor working, it creates or updates a root.key file.

2003 - iana portlist updated.
2005 24 September 2010: Wouter

2008 23 September 2010: Wouter
2009 - unbound-anchor app, unbound requires libexpat (xml parser library).
2011 22 September 2010: Wouter
2012 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
2013 reverse ipv6 orchid prefix from builtin list.
2014 - iana portlist updated.
2016 17 September 2010: Wouter
2017 - DLV has downgrade protection again, because the RFC says so.
2018 - iana portlist updated.
2020 16 September 2010: Wouter
2021 - Algorithm rollover operational reality intrudes, for trust-anchor,
2022 5011-store, and DLV-anchor if one key matches it's good enough.
2023 - iana portlist updated.
2024 - Fix reported validation error in out of memory condition.
2026 15 September 2010: Wouter
2027 - Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
2029 14 September 2010: Wouter

2031 like _tcp.slb.com with 262 servers.
2032 - iana portlist updated.
2034 13 September 2010: Wouter
2035 - bug#327: Fix for cannot access stub zones until the root is primed.
2037 9 September 2010: Wouter
2038 - unresponsive servers are not completely blacklisted (because of
2039 firewalls), but also not probed all the time (because of the request
2040 list size it generates). The probe rate is 1%.
2041 - iana portlist updated.
2043 20 August 2010: Wouter
2044 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
2045 iterator get_mem includes priv_get_mem. delegpt nodup removed.
2046 listen_pushback, query_info_allocqname, write_socket, send_packet,
2047 comm_point_set_cb_arg and listen_resume removed.
2049 19 August 2010: Wouter
2050 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
2051 Delegpt structures checked for duplicates always.
2052 No more nameserver lookups generated when depth is full anyway.

2054 - iana portlist updated.
2056 18 August 2010: Wouter
2057 - Fix bug#322: configure does not respect CFLAGS on Solaris.
2058 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
2059 if use sun-cc, but some systems need different flags.
2061 16 August 2010: Wouter
2062 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
2063 changes, uses m4_bpatsubst now.
2064 - make test (or make check) should be more portable and run the unit
2065 test and testbound scripts. (make longtest has special requirements).
2067 13 August 2010: Wouter
2068 - More pleasant remote control command parsing.
2069 - documentation added for return values reported by doxygen 1.7.1.
2070 - iana portlist updated.
2072 9 August 2010: Wouter

2094 14 July 2010: Wouter
2095 - Donation text added to README.
2096 - Fix integer underflow in prefetch ttl creation from cache. This
2097 fixes a potential negative prefetch ttl.
2099 12 July 2010: Wouter
2100 - Changed the defaults for num-queries-per-thread/outgoing-range.
2101 For builtin-select: 512/960, for libevent 1024/4096 and for
2102 windows 24/48 (because of win api). This makes the ratio this way
2103 to improve resilience under heavy load. For high performance, use
2104 libevent and possibly higher numbers.
2106 10 July 2010: Wouter
2107 - GOST enabled if SSL is recent and ldns has GOST enabled too.
2108 - ldns tarball updated.
2111 - iana portlist updated.
2112 - Fix validation of qtype DNSKEY when a key-cache entry exists but
2113 no rr-cache entry is used (it expired or prefetch), it then goes
2114 back up to the DS or trust-anchor to validate the DNSKEY.
2117 - Neat function prototypes, unshadowed local declarations.
2120 - failure to chown the pidfile is not fatal any more.
2121 - testbound uses UTC timezone.
2122 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
2123 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
2126 - log if a server is skipped because it is on the donotquery list,
2127 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
2128 - added feature to print configure date, target and options with -h.
2129 - added feature to print event backend system details with -h.
2130 - wdiff is not actually required by make test, updated requirements.
2133 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
2134 must be signed with all algorithms from the DS rrset at the parent.
2135 This is now checked and becomes bogus if not.
2137 28 June 2010: Wouter
2138 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
2139 in overload situations to be about 5 qps for the class of shortly
2141 The capacity of the resolver is then about (numqueriesperthread / 2)
2142 / (average time for such long queries) qps for long queries.
2143 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
2144 qps for short queries, per thread.
2145 - Fix the max number of reply-address count to be applied for duplicate
2146 queries, and not for new query list entries. This raises the memory
2147 usage to a max of (16+1)*numqueriesperthread reply addresses.
2149 25 June 2010: Wouter
2150 - Fix handling of corner case reply from lame server, follows rfc2308.
2151 It could lead to a nodata reply getting into the cache if the search
2152 for a non-lame server turned up other misconfigured servers.
2153 - unbound.h has extern "C" statement for easier include in c++.
2155 23 June 2010: Wouter
2156 - iana portlist updated.
2157 - makedist upgraded cross compile openssl option, like this:
2158 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
2160 22 June 2010: Wouter
2161 - Unbound reports libev or libevent correctly in logs in verbose mode.
2162 - Fix to unload gost dynamic library module for leak testing.
2164 18 June 2010: Wouter
2165 - iana portlist updated.
2167 17 June 2010: Wouter
2168 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
2170 16 June 2010: Wouter
2171 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
2172 assertion was wrong.
2173 - updated ldns tarball.
2175 15 June 2010: Wouter
2176 - tag 1.4.5 created.
2177 - trunk contains 1.4.6 in development.
2178 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
2179 - Fix to use one pointer less for iterator query state store_parent_NS.
2180 - makedist crosscompile to windows uses builtin ldns not host ldns.
2181 - Max referral count from 30 to 130, because 128 one character domains
2183 - added documentation for the histogram printout to syslog.
2185 11 June 2010: Wouter
2186 - When retry to parent the retrycount is not wiped, so failed
2187 nameservers are not tried again.
2188 - iana portlist updated.
2190 10 June 2010: Wouter
2191 - Fix bug where a long loop could be entered, now cycle detection
2192 has a loop-counter and maximum search amount.
2195 - iana portlist updated.
2196 - 1.4.5rc1 tag created.
2199 - ldns tarball updated, 1.6.5.
2200 - review comments, split dependency cycle tracking for parentside
2201 last resort lookups for A and AAAA so there are more lookup options.
2204 - Fix compile warning if compiled without threads.
2205 - updated ldns-tarball with current ldns svn (pre 1.6.5).
2206 - GOST disabled-by-default, the algorithm number is allocated but the
2207 RFC is still has to pass AUTH48 at the IETF.
2210 - Ignore Z flag in incoming messages too.
2211 - Fix storage of negative parent glue if that last resort fails.
2212 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
2213 - new splint flags for newer splint install.
2216 - Fix AD flag handling, it could in some cases mistakenly copy the AD
2217 flag from upstream servers.
2218 - alloc_special_obtain out of memory is not a fatal error any more,
2219 enabling unbound to continue longer in out of memory conditions.
2220 - parentside names are dispreferred but not said to be dnssec-lame.
2221 - parentside check for cached newname glue.
2222 - fix parentside and querytargets modulestate, for dump_requestlist.
2223 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
2224 - fix parentside from cache to be marked dispreferred for bad names.
2227 - iana portlist updated.
2228 - parent-child disagreement approach altered. Older fixes are
2229 removed in place of a more exhaustive search for misconfigured data
2230 available via the parent of a delegation.
2231 This is designed to be throttled by cache entries, with TTL from the
2232 parent if possible. Additionally the loop-counter is used.
2233 It also tests for NS RRset differences between parent and child.
2234 The fetch of misconfigured data should be more reliable and thorough.
2235 It should work reliably even with no or only partial data in cache.
2236 Data received from the child (as always) is deemed more
2237 authoritative than information received from the delegation parent.
2238 The search for misconfigured data is not performed normally.
2241 - Contribution from Migiel de Vos (Surfnet): nagios patch for
2242 unbound-host, in contrib/ (in the source tarball). Makes
2243 unbound-host suitable for monitoring dnssec(-chain) status.
2246 - EDNS timeout code will not fire if EDNS status already known.
2247 - EDNS failure not stored if EDNS status known to work.
2250 - Fix resolution for domains like safesvc.com.cn. If the iterator
2251 can not recurse further and it finds the delegation in a state
2252 where it would otherwise have rejected it outhand if so received
2253 from a cache lookup, then it can try to ask higherup (with loop
2255 - Fix comments in iter_utils:dp_is_useless.
2258 - Fix various compiler warnings from the clang llvm compiler.
2259 - iana portlist updated.
2262 - Fix bug#308: spelling error in variable name in parser and lexer.
2265 - Fix dnssec-missing detection that was turned off by server selection.
2266 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
2267 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
2268 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
2270 29 April 2010: Wouter
2271 - Fix for dnssec lameness detection to use the key cache.
2272 - infra cache entries that are expired are wiped clean. Previously
2273 it was possible to not expire host data (if accessed often).
2275 28 April 2010: Wouter
2276 - ldns tarball updated and GOST support is detected and then enabled.
2277 - iana portlist updated.
2278 - Fix detection of gost support in ldns (reported by Chris Smith).
2280 27 April 2010: Wouter
2281 - unbound-control get_option domain-insecure shows config file items.
2282 - fix retry sequence if prime hints are recursion-lame.
2283 - autotrust anchor file can be initialized with a ZSK key as well.
2284 - harden-referral-path does not result in failures due to max-depth.
2285 You can increase the max-depth by adding numbers (' 0') after the
2286 target-fetch-policy, this increases the depth to which is checked.
2288 26 April 2010: Wouter
2289 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
2290 CPPFLAGS during configure process.
2291 - if libev is installed on the base system (not libevent), detect
2292 it from the event.h header file and link with -lev.
2293 - configlexer.lex gets config.h, and configyyrename.h added by make,
2294 no more double include.
2295 - More strict scrubber (Thanks to George Barwood for the idea):
2296 NS set must be pertinent to the query (qname subdomain nsname).
2297 - Fix bug#307: In 0x20 backoff fix fallback so the number of
2298 outstanding queries does not become -1 and block the request.
2299 Fixed handling of recursion-lame in combination with 0x20 fallback.
2300 Fix so RRsets are compared canonicalized and sorted if the immediate
2301 comparison fails, this makes it work around round-robin sites.
2303 23 April 2010: Wouter
2304 - Squelch log message: sendto failed permission denied for
2305 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
2306 - Fix to fetch data as last resort more tenaciously. When cycle
2307 targets cause the server selection to believe there are more options
2308 when they really are not there, the server selection is reinitiated.
2309 - Fix fetch from blacklisted dnssec lame servers as last resort. The
2310 server's IP address is then given in validator errors as well.
2311 - Fix local-zone type redirect that did not use the query name for
2314 22 April 2010: Wouter
2316 - trunk contains 1.4.5 in development.
2317 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
2318 The validator error message was 'no signatures from ...'.
2320 16 April 2010: Wouter
2321 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
2324 15 April 2010: Wouter
2325 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
2326 example key and signatures for GOST. GOST requires openssl-1.0.0.
2327 GOST is still disabled by default.
2329 9 April 2010: Wouter
2330 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
2331 get into an endless loop, if 0x20 was enabled, and buffers are small
2332 or particular broken packets are received.
2333 - Fix chain of trust with CNAME at an intermediate step, for the DS
2336 8 April 2010: Wouter
2337 - Fix validation of queries with wildcard names (*.example).
2339 6 April 2010: Wouter
2340 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
2341 cache timeout coincided with a server update, the current EDNS
2342 backoff is less sensitive, and does not cache the backoff unless
2343 the backoff actually works and the domain is not expecting DNSSEC.
2344 - GOST support with correct algorithm numbers.
2346 1 April 2010: Wouter
2347 - iana portlist updated.
2349 24 March 2010: Wouter
2350 - unbound control flushed items are not counted when flushed again.
2352 23 March 2010: Wouter
2353 - iana portlist updated.
2355 22 March 2010: Wouter
2356 - unbound-host disables use-syslog from config file so that the
2357 config file for the main server can be used more easily.
2358 - fix bug#301: unbound-checkconf could not parse interface
2359 '0.0.0.0@5353', even though unbound itself worked fine.

2374 - for NSEC3 check if signatures are cached.
2376 15 March 2010: Wouter
2377 - unit test for util/regional.c.
2379 12 March 2010: Wouter
2380 - Reordered configure checks so fork and -lnsl -lsocket checks are
2381 earlier, and thus later checks benefit from and do not hinder them.
2382 - iana portlist updated.
2383 - ldns tarball updated.
2384 - Fix python use when multithreaded.
2385 - Fix solaris python compile.

2404 - tag 1.4.2 created.
2405 - trunk is 1.4.3 in development.
2406 - --enable-alloc-lite debug option.
2408 8 March 2010: Wouter

2416 - iana portlist updated.
2418 1 March 2010: Wouter
2419 - make install depends on make all.

2436 - Also delete potential poison references from additional.
2437 - Fix: no classification of a forwarder as lame, throw away instead.
2439 23 February 2010: Wouter
2440 - libunbound ub_ctx_get_option() added.
2441 - unbound-control set_option and get_option commands.
2442 - iana portlist updated.
2444 18 February 2010: Wouter
2445 - A little more strict DS scrubbing.
2446 - No more blacklisting of unresponsive servers, a 2 minute timeout
2448 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.

2459 16 February 2010: Wouter
2460 - Check for 'no space left on device' (or other errors) when
2461 writing updated autotrust anchors and print errno to log.
2463 15 February 2010: Wouter
2464 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
2465 hardcoded. We made the choice to send out more conservatively,
2466 protecting against an aggregate effect more than protecting a
2467 single user (from their own folly, perhaps in case of misconfig).
2469 12 February 2010: Wouter
2470 - Re-query pattern changed on validation failure. To protect troubled
2471 authority servers, unbound caches a failure for the DNSKEY or DS
2472 records for the entire zone, and only retries that 900 seconds later.
2473 This implies that only a handful of packets are sent extra to the
2474 authority if the zone fails.
2476 11 February 2010: Wouter
2477 - ldns tarball update for long label length syntax error fix.
2478 - iana portlist updated.

2504 14 January 2010: Wouter
2505 - Fixup ldns detection to also check for header files.
2507 13 January 2010: Wouter
2508 - prefetch-key option that performs DNSKEY queries earlier in the
2509 validation process, and that could halve the latency on DNSSEC
2510 queries. It takes some extra processing (CPU, a cache is needed).
2512 12 January 2010: Wouter
2513 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
2515 8 January 2010: Wouter
2516 - Fix for parent-child disagreement code which could have trouble
2517 when (a) ipv6 was disabled and (b) the TTL for parent and child
2518 were different. There were two bugs, the parent-side information
2519 is fixed to no longer block lookup of child side information and
2520 the iterator is fixed to no longer attempt to get ipv6 when it is
2521 not enabled and then give up in failure.
2522 - test and fixes to make prefetch actually store the answer in the
2523 cache. Considers some rrsets 'already expired' but does not allow
2524 overwriting of rrsets considered more secure.
2526 7 January 2010: Wouter
2527 - Fixup python documentation (thanks Leo Vandewoestijne).
2528 - Work on cache prefetch feature.

2530 and in unbound_munin plugin.
2532 6 January 2010: Wouter
2533 - iana portlist updated.

2564 9 December 2009: Wouter
2565 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
2566 errors generated for domain names like '.example.com'.
2567 - Fix SOA excluded from negative DS responses. Reported by Hauke
2568 Lampe. The negative cache did not include proper SOA records for
2569 negative qtype DS responses which makes BIND barf on it, such
2570 responses are now only used internally.
2571 - Fix negative cache lookup of closestencloser check of DS type bit.
2573 8 December 2009: Wouter
2574 - Fix for lookup of parent-child disagreement domains, where the
2575 parent-side glue works but it does not provide proper NS, A or AAAA
2576 for itself, fixing domains such as motorcaravanners.eu.
2577 - Feature: you can specify a port number in the interface: line, so
2578 you can bind the same interface multiple times at different ports.
2580 7 December 2009: Wouter
2581 - Bug#287: Fix segfault when unbound-control remove nonexistent local
2582 data. Added check to tests.
2584 1 December 2009: Wouter

2598 23 November 2009: Wouter
2599 - Patch from David Hubbard for libunbound manual page.
2600 - Fixup endless spinning in unbound-control stats reported by
2601 Attila Nagy. Probably caused by clock reversal.
2603 20 November 2009: Wouter

2624 long ANY mix cases, which fixes validation failures.
2626 12 November 2009: Wouter
2627 - iana portlist updated.
2628 - fix manpage errors reported by debian lintian.
2630 - fixup very long vallog2 level error strings.

2659 - RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
2660 - ldns tarball updated (which also enables rsasha256 support).
2662 27 October 2009: Wouter
2663 - iana portlist updated.
2665 8 October 2009: Wouter
2667 - add val-log-level print to corner case (nameserver.epost.bg).
2668 - more detail to errors from insecure delegation checks.
2669 - Fix double time subtraction in negative cache reported by
2670 Amanda Constant and Hugh Mahon.
2671 - Made new validator error string available from libunbound for
2672 applications. It is in result->why_bogus, a zero-terminated string.
2673 unbound-host prints it by default if a result is bogus.
2674 Also the errinf is public in module_qstate (for other modules).
2676 7 October 2009: Wouter
2677 - retry for validation failure in DS and prime results. Less mem use.
2678 unit test. Provisioning in other tests for requeries.

2685 - moved version number to 1.4.0 because of 1.3.4 release with only
2686 the NSEC3 patch from the entry above.
2687 - val-log-level: 2 shows extended error information for validation
2688 failures, but still one (longish) line per failure. For example:
2689 validation failure <example.com. DNSKEY IN>: signature expired from
2690 192.0.2.4 for trust anchor example.com. while building chain of trust
2691 validation failure <www.example.com. A IN>: no signatures from
2692 192.0.2.6 for key example.com. while building chain of trust
2694 6 October 2009: Wouter
2695 - Test set updated to provide additional ns lookup result.
2696 The retry would attempt to fetch the data from other nameservers
2697 for bogus data, and this needed to be provisioned in the tests.
2699 5 October 2009: Wouter
2700 - first validation failure retry code. Retries for data failures.
2703 2 October 2009: Wouter
2704 - improve 5011 modularization.
2705 - fix unbound-host so -d can be given before -C.

2712 - review fixes to comments, removed unused code.
2714 25 September 2009: Wouter
2715 - so-rcvbuf: 4m option added. Set this on large busy servers to not
2716 drop the occasional packet in spikes due to full socket buffers.
2717 netstat -su keeps a counter of UDP dropped due to full buffers.
2718 - review of validator/autotrust.c, small fixes and comments.
2720 23 September 2009: Wouter
2721 - 5011 query failed counts verification failures, not lookup failures.
2722 - 5011 probe failure handling fixup.
2723 - test unbound reading of original autotrust data.
2724 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
2725 picked up, otherwise performs initial probe like usual.
2727 22 September 2009: Wouter
2728 - autotrust test with algorithm rollover, new ordering of checks
2729 assists in orderly rollover.
2730 - autotrust test with algorithm rollover to unknown algorithm.
2731 checks if new keys are supported before adding them.
2732 - autotrust test with trust point revocation, becomes unsigned.
2733 - fix DNSSEC-missing-signature detection for minimal responses
2734 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
2736 18 September 2009: Wouter
2737 - autotrust tests, fix trustpoint timer deletion code.
2738 fix count of valid anchors during missing remove.
2739 - autotrust: pick up REVOKE even if not signed with known other keys.

2750 15 September 2009: Wouter
2751 - iana portlist updated.
2753 10 September 2009: Wouter
2754 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
2755 - use linebuffering for log-file: output, this can be significantly
2756 faster than the previous fflush method and enable some class of
2757 resolvers to use high verbosity (for short periods).
2758 Not on windows, because line buffering does not work there.
2760 9 September 2009: Wouter
2761 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
2762 The RRsets would still expire at the normal time, but this would
2763 keep messages bogus in the cache for too long.
2764 - regression test for that bug.
2765 - documented that load_cache is meant for debugging.
2767 8 September 2009: Wouter
2768 - fixup printing errors when load_cache, they were printed to the

2779 - Changes to make unbound work with libevent-2.0.3 alpha. (in
2780 configure detection due to new ssl dependency in libevent)
2781 - do not call sphinx for documentation when python is disabled.
2782 - remove EV_PERSIST from libevent timeout code to make the code
2783 compatible with the libevent-2.0. Works with older libevent too.

2850 - autotrust work, split up DS verification of DNSKEYs.
2852 14 August 2009: Wouter
2853 - unbound-control lookup prints out infra cache information, like RTT.
2854 - Fix bug in DLV lookup reported by Amanda from Secure64.
2855 It could sometimes wrongly classify a domain as unsigned, which
2856 does not give the AD bit on replies.

2859 - autotrust read anchor files. locked trust anchors.
2861 12 August 2009: Wouter

2905 - Fix server selection, so that it waits for open target queries when
2906 faced with lameness.
2908 20 July 2009: Wouter

2922 - package libgcc_s_sjlj exception handler for NSISdl.dll.
2924 14 July 2009: Wouter
2925 - updated ldns tarball for solaris x64 compile assistance.
2926 - no need to define RAND_MAX from config.h.
2927 - iana portlist updated.
2928 - configure changes and ldns update for mingw32 crosscompile.
2930 13 July 2009: Wouter

2955 29 June 2009: Wouter
2956 - ldns trunk r2959 imported as tarball, because of solaris cc compile
2957 support for c99. r2960 for better configure.
2958 - better wrongly_truncated check.
2959 - On Linux, fragment IPv6 datagrams to the IPv6 minimum MTU, to
2960 avoid dropped packets at routers.
2962 26 June 2009: Wouter
2963 - Fix EDNS fallback when EDNS works for short answers but long answers
2966 22 June 2009: Wouter

2976 - harden-referral-path: handle cases where NS is in answer section.
2978 18 June 2009: Wouter
2979 - Fix of message parse bug where (specifically) an NSEC and RRSIG
2980 in the wrong order would be parsed, but put wrongly into internal
2981 structures so that later validation would fail.
2982 - Extreme lenience for wrongly truncated replies where a positive
2983 reply has an NS in the authority but no signatures. They are
2984 turned into minimal responses with only the (secure) answer.
2985 - autoconf 2.63 for configure.
2986 - python warnings suppress. Keep python API away from header files.
2988 17 June 2009: Wouter
2989 - CREDITS entry for cz.nic, sponsoring a 'summer of code' that was
2990 used for the python code in unbound. (http://www.nic.cz/vip/ in cz).
2992 16 June 2009: Wouter
2993 - Fixup opportunistic target query generation to it does not
2994 generate queries that are known to fail.
2995 - Touchup on munin total memory report.
2996 - messages picked out of the cache by the iterator are checked
2997 if their cname chain is still correct and if validation status
2998 has to be reexamined.
3000 15 June 2009: Wouter
3001 - iana portlist updated.
3003 14 June 2009: Wouter
3004 - Fixed bug where cached responses would lose their security
3005 status on second validation, which especially impacted dlv
3006 lookups. Reported by Hauke Lampe.
3008 13 June 2009: Wouter
3009 - bug #254. removed random whitespace from example.conf.
3011 12 June 2009: Wouter
3012 - Fixup potential wrong NSEC picked out of the cache.
3013 - If unfulfilled callbacks are deleted they are called with an error.
3014 - fptr wlist checks for mesh callbacks.
3015 - fwd above stub in configuration works.
3017 11 June 2009: Wouter
3018 - Fix queries for type DS when forward or stub zones are there.
3019 They are performed to higherup domains, and thus treated as if
3020 going to higher zones when looking up the right forward or stub
3021 server. This makes a stub pointing to a local server that has
3022 a local view of example.com signed with the same keys as are
3023 publicly used work. Reported by Johan Ihren.
3024 - Added build-unbound-localzone-from-hosts.pl to contrib, from
3025 Dennis DeDonatis. It converts /etc/hosts into config statements.
3026 - same thing fixed for forward-zone and DS, chain of trust from
3027 public internet into the forward-zone works now. Added unit test.
3030 - openssl key files are opened apache-style, when user is root and
3031 before chrooting. This makes permissions on remote-control key
3032 files easier to set up. Fixes bug #251.
3033 - flush_type and flush_name remove msg cache entries.
3034 - codereview - dp copy bogus setting fix.
3037 - Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
3038 inadvertant behaviour.

3043 - help compiler figure out aliasing in priv_rrset_bad() routine.
3044 - fail to configure with python if swig is not found.
3045 - unbound_munin_ in contrib uses ps to show rss if sbrk does not work.
3048 - fixup bad free() when wrongly encoded DSA signature is seen.
3049 Reported by Paul Wouters.
3050 - review comments from Matthijs.
3053 - --enable-sha2 option. The draft rsasha256 changed its algorithm
3054 numbers too often. Therefore it is more prudent to disable the
3055 RSASHA256 and RSASHA512 support by default.
3056 - ldns trunk included as new tarball.
3057 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.
3060 - fixup doc bug in README reported by Matthew Dempsky.
3063 - update iana port list
3064 - update ldns lib tarball
3067 - detect lack of IPv6 support on XP (with a different error code).
3068 - Fixup a crash-on-exit which was triggered by a very long queue.
3069 Unbound would try to re-use ports that came free, but this is
3070 of course not really possible because everything is deleted.
3071 Most easily triggered on XP (not Vista), maybe because of the
3072 network stack encouraging large messages backlogs.
3073 - change in debug statements.
3074 - Fixed bug that could cause a crash if root prime failed when there
3075 were message backlogs.
3078 - Thanks again to Brett Carr, found an assertion that was not true.
3079 Assertion checked if recursion parent query still existed.
3081 29 April 2009: Wouter
3082 - Thanks to Brett Carr, caught windows resource leak, use
3083 closesocket() and not close() on sockets or else the network stack
3084 starts to leak handles.
3085 - Removed usage of windows Mutex because windows cannot handle enough
3086 mutexes open. Provide own mutex implementation using primitives.

3137 - windows compile fix.
3138 - Detect FreeBSD jail without ipv6 addresses assigned.
3139 - python libunbound wrapper unit test.

3143 from configure --with-pyunbound:
3144 /usr/lib/python2.x/site-packages/unbound.py
3145 /usr/lib/python2.x/site-packages/_unbound.so*
3146 The example python scripts (pythonmod/examples and

3149 - clock skew checks in unbound, config statements.
3150 - nxdomain ttl considerations in requirements.txt
3152 3 April 2009: Wouter
3153 - Fixed a bug that caused messages to be stored in the cache too
3154 long. Hard to trigger, but NXDOMAINs for nameservers or CNAME
3155 targets have been more vulnerable to the TTL miscalculation bug.
3156 - documentation test fixed for python addition.
3158 2 April 2009: Wouter
3159 - pyunbound (libunbound python plugin) compiles using libtool.

3165 - python module test package.
3167 1 April 2009: Wouter
3168 - suppress errors when trying to contact authority servers that gave

3223 - defaults for windows baked into configure.ac (used if on mingw).
3225 18 March 2009: Wouter
3226 - Added tests, unknown algorithms become insecure. fallback works.
3227 - Fix for and test for unknown algorithms in a trust anchor
3228 definition. Trust anchors with no supported algos are ignored.
3229 This means a (higher)DS or DLV entry for them could succeed, and
3230 otherwise they are treated as insecure.
3231 - domain-insecure: "example.com" statement added. Sets domain
3232 insecure regardless of chain of trust DSs or DLVs. The inverse
3235 17 March 2009: Wouter
3236 - unit test for unsupported algorithm in anchor warning.
3237 - fixed so queries do not fail on opportunistic target queries.
3239 16 March 2009: Wouter

3250 - remove debugging from windows 'cron' actions.
3252 12 March 2009: Wouter
3253 - log to App.logs on windows prints executable identity.
3255 - munin plugin fix benign locking error printout.
3256 - anchor-update for windows, called every 24 hours; unbound reloads.
3258 11 March 2009: Wouter
3259 - winsock event handler resets WSAevents after signalled.
3260 - winsock event handler tests if signals are really signalled.
3261 - install and service with log to file works on XP and Vista on
3262 default install location.
3263 - on windows logging to the Application logbook works (as a service).
3264 - fix RUN_DIR on windows compile setting in makedist.
3265 - windows registry has Software\Unbound\ConfigFile element.
3266 If does not exist, the default is used. The -c switch overrides it.

3314 - unbound-checkconf and unbound print warnings when trust anchors
3315 have unsupported algorithms.
3316 - added contrib/update-itar.sh This script is similar to
3317 update-anchor.sh, and updates from the IANA ITAR repository.
3318 You can provide your own PGP key and trust repo, or can use the
3319 builtin. The program uses wget and gpg to work.
3320 - iana portlist updated.
3321 - update-itar.sh: using ftp:// urls because https godaddy certificate
3322 is not available everywhere and then gives fatal errors. The
3323 security is provided by pgp signature.
3325 18 February 2009: Wouter
3326 - more cycle detection. Also for target queries.
3327 - fixup bug where during deletion of the mesh queries the callbacks
3328 that were reentrant caused assertion failures. Keep the mesh in
3329 a reentrant safe state. Affects libunbound, reload of server,
3330 on quit and flush_requestlist.
3331 - iana portlist updated.
3333 13 February 2009: Wouter
3334 - forwarder information now per-thread duplicated.
3335 This keeps it read only for speed, with no locking necessary.
3336 - forward command for unbound control to change forwarders to use
3338 - document that unbound-host reads no config file by default.
3339 - updated iana portlist.
3341 12 February 2009: Wouter
3342 - call setusercontext if available (on BSD).
3343 - small refactor of stats clearing.

3351 10 February 2009: Wouter
3352 - keys with rfc5011 REVOKE flag are skipped and not considered when
3354 - iana portlist updated
3355 - #226: dump_requestlist feature for unbound-control.
3357 6 February 2009: Wouter
3358 - contrib contains specfile for fedora 1.2.1 (from Paul Wouters).

3361 You can no longer specify newlines in the names of included files.
3362 - config parser changed. Gives some syntax errors closer to where they
3363 occurred. Does not enforce a space after keyword anymore.
3364 Does not allow literal newlines inside quoted strings anymore.
3365 - verbosity level 5 logs customer IP for new requestlist entries.
3366 - test fix, lexer and cancel test.
3367 - new option log-time-ascii: yes if you enable it prints timestamps
3368 in the log file as Feb 06 13:45:26 (like syslog does).
3369 - detect event_base_new in libevent-1.4.1 and later and use it.
3370 - #231 unbound-checkconf -o option prints that value from config file.
3371 Useful for scripting in management scripts and the like.
3373 5 February 2009: Wouter
3374 - ldns 1.5.0 rc as tarball included.
3375 - 1.3.0 development continues:
3376 change in libunbound API: ub_cancel can return an error, that
3377 the async_id did not exist, or that it was already delivered.
3378 The result could have been delivered just before the cancel
3379 routine managed to acquire the lock, so a caller may get the
3380 result at the same time they call cancel. For this case,
3381 ub_cancel tries to return an error code.
3382 Fixes race condition in ub_cancel() libunbound function.
3383 - MacOSX Leopard cleaner text output from configure.
3384 - initgroups(3) is called to drop secondary group permissions, if
3386 - configure option --with-ldns-builtin forces the use of the
3387 inluded ldns package with the unbound source. The -I include
3388 is put before the others, so it avoids bad include files from
3389 an older ldns install.
3390 - daemon(3) posix call is used when available.
3391 - testbound test for older fix added.
3393 4 February 2009: Wouter
3394 - tag for release 1.2.1.
3395 - trunk setup for 1.3.0 development.

3400 - updated IANA portlist.
3402 16 January 2009: Wouter
3403 - more quiet about ipv6 network failures, i.e. when ipv6 is not
3404 available (network unreachable). Debug still printed on high
3406 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
3407 debugging with unbound-host -4 -d ...
3408 - more cycle detection for NS-check, addr-check, root-prime and
3409 stub-prime queries in the iterator. Avoids possible deadlock
3412 15 January 2009: Wouter
3413 - bug #229: fixup configure checks for compilation with Solaris
3414 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc

3416 - fix bug where unbound could crash using libevent 1.3 and older.
3417 - update testset for recent retry change.
3419 14 January 2009: Wouter
3420 - 1.2.1 feature: negative caching for failed queries.
3421 Queries that failed are cached for 5 seconds (NORR_TTL).
3422 If the failure is local, like out of memory, it is not cached.
3423 - the TTL comparison for the cache used different comparisons,
3424 causing many cache responses that used the iterator and validator
3425 state machines unnecessarily.
3426 - retry from 4 to 5 so that EDNS drop retry is part of the first
3427 query resolve attempt, and cached error does not stop EDNS fallback.
3428 - remove debug prints that protect against bad referrals.
3429 - honor QUIET=no on make commandline (or QUIET=yes ).
3431 13 January 2009: Wouter

3437 are in the negative cache.
3439 12 January 2009: Wouter
3440 - fixed bug in infrastructure lameness cache, did not lowercase
3441 name of zone to hash when setting lame.
3442 - lameness debugging printouts.
3444 9 January 2009: Wouter
3445 - created svn tag for 1.2.0 release.
3446 - svn trunk contains 1.2.1 version number.
3447 - iana portlist updated for todays list.
3448 - removed debug print.
3450 8 January 2009: Wouter
3451 - new version of ldns-trunk (today) included as tarball, fixed
3452 bug #224, building with -j race condition.
3453 - remove possible race condition in the test for race conditions.
3455 7 January 2009: Wouter
3456 - version 1.2.0 in preparation.
3457 - feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
3458 statements. (Adapted from patch by Paul Wouters).
3459 - typo fix and iana portlist updated.
3460 - porting testsuite; unused var warning, and type fixup.
3462 6 January 2009: Wouter

3464 A malformed packet could cause an internal assertion failure.
3465 - added test for HINFO canonicalisation behaviour.
3466 - fixup reported problem with transparent local-zone data where
3467 queries with different type could get nxdomain. Now queries
3468 with a different name get resolved normally, with different type
3469 get a correct NOERROR/NODATA answer.
3470 - HINFO no longer downcased for validation, making unbound compatible
3472 - fix reading included config files when chrooted.
3473 Give full path names for include files.
3474 Relative path names work if the start dir equals the working dir.

3481 - comm_timer_set performs base_set operation after event_add.
3483 18 December 2008: Wouter
3484 - fixed bug reported by Duane Wessels: error in DLV lookup, would make
3485 some zones that had correct DLV keys as insecure.
3486 - follows -rc makedist from ldns changes (no _rc).
3487 - ldns tarball updated with 1.4.1rc for DLV unit test.
3488 - verbose prints about recursion lame detection and server selection.
3489 - fixup BSD port for infra host storage. It hashed wrongly.
3490 - fixup makedist snapshot name generation.
3491 - do not reopen syslog to avoid dev/log dependency.

3494 - follows ldns makedist.sh. -rc option. autom4te dir removed.
3495 - unbound-control status command.
3496 - extended statistics has a number of ipv6 queries counter.
3497 contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
3499 16 December 2008: Wouter
3500 - follow makedist improvements from ldns, for maintainers prereleases.
3501 - snapshot version uses _ not - to help rpm distinguish the
3504 11 December 2008: Wouter
3505 - better fix for bug #219: use LOG_NDELAY with openlog() call.
3506 Thanks to Tamas Tevesz.
3508 9 December 2008: Wouter
3509 - bug #221 fixed: unbound checkconf checks if key files exist if
3510 remote control is enabled. Also fixed NULL printf when not chrooted.
3511 - iana portlist updated.
3513 3 December 2008: Wouter
3514 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
3515 freezes up unbound if this was compiled without threading, and
3516 was using multiple processes.
3517 - iana portlist updated.
3518 - test for remote control with interprocess communication.
3519 - created command distribution mechanism so that remote control
3520 commands other than 'stats' work on all processes in a nonthreaded
3521 compiled version. dump/load cache work, on the first process.
3522 - fixup remote control local_data addition memory corruption bug.
3524 1 December 2008: Wouter
3525 - SElinux policy files in contrib/selinux for the unbound daemon,
3526 by Paul Wouters and Adam Tkac.
3528 25 November 2008: Wouter
3529 - configure complains when --without-ssl is given (bug #220).
3530 - skip unsupported feature tests on vista/mingw.
3531 - fixup testcode/streamtcp to work on vista/mingw.
3532 - root-hints test checks version of dig required.
3533 - blacklisted servers are polled at a low rate (1%) to see if they
3534 come back up. But not if there is some other working server.
3536 24 November 2008: Wouter
3537 - document that the user of the server daemon needs read privileges
3538 on the keys and certificates generated by unbound-control-setup.
3539 This is different per system or distribution, usually, running the
3540 script under the same username as the server uses suffices.
3541 i.e. sudo -u unbound unbound-control-setup
3542 - testset port to vista/mingw.
3543 - tcp_sigpipe to freebsd port.
3545 21 November 2008: Wouter
3546 - fixed tcp accept, errors were printed when they should not.
3547 - unbound-control-setup.sh removes read/write permissions other
3548 from the keys it creates (as suggested by Dmitriy Demidov).
3550 20 November 2008: Wouter
3551 - fixup fatal error due to faulty error checking after tcp accept.
3552 - add check in rlimit to avoid integer underflow.
3553 - rlimit check with new formula; better estimate for number interfaces
3554 - nicer comments in rlimit check.
3555 - tag 1.1.1 created in svn.
3556 - trunk label is 1.1.2
3558 19 November 2008: Wouter
3559 - bug #219: fixed so that syslog which delays opening until the first
3560 log line is written, gets a log line while not chroot'ed yet.
3562 18 November 2008: Wouter
3563 - iana portlist updated.
3564 - removed cast in unit test debug print that was not 64bit safe.
3565 - trunk back to 1.1.0; copied to tags 1.1.0 release.
3566 - trunk to has version number 1.1.1 again.
3567 - in 1.1.1; make clean nicer. grammar in manpage.
3569 17 November 2008: Wouter
3570 - theoretical fix for problems reported on mailing list.
3571 If a delegation point has no A but only AAAA and do-ip6 is no,
3572 resolution would fail. Fixed to ask for the A and AAAA records.
3573 It has to ask for both always, so that it can fail quietly, from
3574 TLD perspective, when a zone is only reachable on one transport.
3575 - test for above, only AAAA and doip6 is no. Fix causes A record
3576 for nameserver to be fetched.
3577 - fixup address duplication on cache fillup for delegation points.
3578 - testset updated for new query answer requirements.
3580 14 November 2008: Wouter

3588 - neater comments in worker.h.
3589 - removed doc/plan and updated doc/TODO.
3590 - silenced EHOSTDOWN (verbosity 2 or higher to see it).
3591 - review comments from Jelte, Matthijs. Neater code.
3593 12 November 2008: Wouter
3594 - add unbound-control manpage to makedist replace list.
3596 11 November 2008: Wouter
3597 - unit test for negative cache, stress tests the refcounting.
3598 - fix for refcounting error that could cause fptr_wlist fatal exit
3599 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
3600 Attila Nagy for testing).
3601 - nicer comments in cachedump about failed RR to string conversion.
3602 - fix 32bit wrap around when printing large (4G and more) mem usage
3603 for extended statistics.
3605 10 November 2008: Wouter

3616 - dname_priv must decompress the name before comparison.
3617 - iana portlist updated.
3619 5 November 2008: Wouter
3620 - fixed possible memory leak in key_entry_key deletion.
3621 Would leak a couple bytes when trust anchors were replaced.
3622 - if query and reply qname overlap, the bytes are skipped not copied.
3623 - fixed file descriptor leak when messages were jostled out that
3624 had outstanding (TCP) replies.
3625 - DNAMEs used from cache have their synthesized CNAMEs initialized
3627 - fixed file descriptor leak for localzone type deny (for TCP).
3628 - fixed memleak at exit for nsec3 negative cached zones.
3629 - fixed memleak for the keyword 'nodefault' when reading config.
3630 - made verbosity of 'edns incapable peer' warning higher, so you
3631 do not get spammed by it.
3632 - caught elusive Bad file descriptor error bug, that would print the
3633 error while unnecessarily try to listen to a closed fd. Fixed.
3635 4 November 2008: Wouter
3636 - fixed -Wwrite-strings warnings that result in better code.
3638 3 November 2008: Wouter
3639 - fixup build process for Mac OSX linker, use ldns b32 compat funcs.
3640 - generated configure with autoconf-2.61.
3641 - iana portlist updated.
3642 - detect if libssl needs libdl. For static linking with libssl.
3643 - changed to use new algorithm identifiers for sha256/sha512
3644 from ldns 1.4.0 (need very latest version).
3645 - updated the included ldns tarball.
3646 - proper detection of SHA256 and SHA512 functions (not just sizes).
3648 23 October 2008: Wouter
3649 - a little more debug info for failure on signer names. prints names.
3651 22 October 2008: Wouter
3652 - CFLAGS are picked up by configure from the environment.
3653 - iana portlist updated.
3654 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
3655 - new stub-prime: yesno option. Default is off, so it does not prime.
3656 can be turned on to get same behaviour as previous unbound release.
3657 - made automated test that checks if builtin root hints are uptodate.
3658 - finished draft-wijngaards-dnsext-resolver-side-mitigation
3659 implementation. The unwanted-reply-threshold can be set.
3660 - fixup so fptr_whitelist test in alloc.c works.
3662 21 October 2008: Wouter
3663 - fix update-anchors.sh, so it does not report different RR order
3664 as an update. Sorts the keys in the file. Updated copyright.
3665 - fixup testbound on windows, the command control pipe doesn't exist.
3666 - skip 08hostlib test on windows, no fork() available.
3667 - made unbound-remote work on windows.
3669 20 October 2008: Wouter
3670 - quench a log message that is debug only.
3671 - iana portlist updated.
3672 - do not query bogus nameservers. It is like nameservers that have
3673 the NS or A or AAAA record bogus are listed as donotquery.
3674 - if server selection is faced with only bad choices, it will
3675 attempt to get more options to be fetched.
3676 - changed bogus-ttl default value from 900 to 60 seconds.
3677 In anticipation that operator caused failures are more likely than
3678 actual attacks at this time. And thus repeated validation helps
3679 the operators get the problem fixed sooner. It makes validation
3680 failures go away sooner (60 seconds after the zone is fixed).
3681 Also it is likely to try different nameserver targets every minute,
3682 so that if a zone is bad on one server but not another, it is
3683 likely to pick up the 'correct' one after a couple minutes,
3684 and if the TTL is big enough that solves validation for the zone.
3685 - fixup unbound-control compilation on windows.
3687 17 October 2008: Wouter
3688 - port Leopard/G5: fixup type conversion size_t/uint32.
3689 please ranlib, stop file without symbols warning.
3690 - harden referral path now also validates the root after priming.
3691 It looks up the root NS authoritatively as well as the root servers
3692 and attemps to validate the entries.
3694 16 October 2008: Wouter
3695 - Fixup negative TTL values appearing (reported by Attila Nagy).
3697 15 October 2008: Wouter
3698 - better documentation for 0x20; remove fallback TODO, it is done.
3699 - harden-referral-path feature includes A, AAAA queries for glue,
3700 as well as very careful NS caching (only when doing NS query).
3701 A, AAAA use the delegation from the NS-query.
3703 14 October 2008: Wouter
3704 - fwd_three.tpkg test was flaky. If the three requests hit the
3705 wrong threads by chance (or bad OS) then the test would fail.
3706 Made less flaky by increasing number of retries.
3707 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
3708 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
3709 Which includes the ldns_dname_absolute fix.
3710 - fwd_three test remains flaky now that unbound does not stop
3711 listening when full. Thus, removed timeout problem.
3712 It may be serviced by three threads, or maybe by one.
3713 Mostly only useful for lock-check testing now.
3715 13 October 2008: Wouter
3716 - fixed recursion servers deployed as authoritative detection, so
3717 that as a last resort, a +RD query is sent there to get the
3719 - iana port list update.
3720 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
3722 10 October 2008: Wouter
3723 - fixup tests - the negative cache contained the correct NSEC3s for
3724 two tests that are supposed to fail to validate.
3726 9 October 2008: Wouter
3727 - negative cache caps max iterations of NSEC3 done.
3728 - NSEC3 negative cache for qtype DS works.
3730 8 October 2008: Wouter
3731 - NSEC negative cache for DS.
3733 6 October 2008: Wouter
3734 - jostle-timeout option, so you can config for slow links.
3735 - 0x20 fallback code. Tries 3xnumber of nameserver addresses
3736 queries that must all be the same. Sent to random nameservers.
3737 - documented choices for DoS, EDNS, 0x20.
3739 2 October 2008: Wouter
3740 - fixup unlink of pidfile.
3741 - fixup SHA256 algorithm collation code.
3742 - contrib/update-anchor.sh does not overwrite anchors if not needed.
3743 exits 0 when a restart is needed, other values if not.
3744 so, update-anchor.sh -d mydir && /etc/rc.d/unbound restart
3745 can restart unbound exactly when needed.
3747 30 September 2008: Wouter
3748 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
3749 - tests for sha256 support and downgrade resistance.
3750 - RSASHA256 and RSASHA512 support (using the draft in dnsext),
3751 using the drafted protocol numbers.
3752 - when using stub on localhost (127.0.0.1@10053) unbound works.
3753 Like when running NSD to host a local zone, on the same machine.
3754 The noprime feature. manpages more explanation. Added a test for it.
3755 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
3757 29 September 2008: Wouter
3758 - EDNS lameness detection, if EDNS packets are dropped this is
3759 detected, eventually.
3760 - multiple query timeout rtt backoff does not backoff too much.
3762 26 September 2008: Wouter
3763 - tests for remote-control.
3764 - small memory leak in exception during remote control fixed.
3765 - fixup for lock checking but not unchecking in remote control.
3766 - iana portlist updated.

3834 - private-address and private-domain config option read, stored.
3836 2 September 2008: Wouter
3837 - DoS protection features. Queries are jostled out to make room.
3838 - testbound can pass time, increasing the internal timer.
3839 - do not mark unsigned additionals bogus, leave unchecked, which
3842 1 September 2008: Wouter
3843 - disallow nonrecursive queries for cache snooping by default.
3844 You can allow is using access-control: <subnet> allow_snoop.
3845 The defaults do allow access no authoritative data without RD bit.
3846 - two tests for it and fixups of tests for nonrec refused.

3855 again. (from bugfix#199).
3856 Some errors are not written to logfile (pidfile writing, forking),
3857 and these are only visible by using the -d commandline flag.
3859 27 August 2008: Wouter
3860 - daemon(3) is causing problems for people. Reverting the patch.
3861 bug#200, and 199 and 203 contain sideline discussion on it.

4020 not been fully handled yet. when interest in the event(s) resumes,
4021 they are sent again. When WOULDBLOCK is returned events are cleared.
4022 - skip tests that need signals when testing on mingw.
4024 18 June 2008: Wouter
4025 - open testbound replay files in binary mode, because fseek/ftell
4026 do not work in ascii-mode on windows. The b does nothing on unix.
4027 unittest and testbound tests work on windows (xp too).
4028 - ioctlsocket prints nicer error message.

4033 17 June 2008: Wouter
4034 - outgoing num fds 32 by default on windows ; it supports less
4035 fds for waiting on than unixes.
4036 - winsock_event minievent handler for windows. (you could also
4037 attempt to link with libevent/libev ports for windows).
4038 - neater crypto check and gdi32 detection.
4039 - unbound.exe works to resolve and validate www.nlnetlabs.nl on vista.

4097 - bug 185: --disable-shared not passed along to ldns included with
4098 unbound. Fixed so that configure parameters are passed to the
4099 subdir configure script.
4100 fixed that ./libtool is used always, you can still override
4101 manually with ./configure libtool=mylibtool or set $libtool in
4103 - update of the ldns tarball to current ldns svn version (fix 181).

4195 It will detect and convert when necessary.
4197 14 April 2008: Wouter
4198 - got update for parseunbound.pl statistics script from Kai Storbeck.
4199 - tpkg tests for udp wait list.
4200 - documented 0x20 status.
4201 - fixup chroot and checkconf, it is much smarter now.

4203 - and check first sig byte for the encoding type.
4205 11 April 2008: Wouter
4206 - random port selection out of the configged ports.
4207 - fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
4208 - removed base_port.
4209 - created 256-port ephemeral space for the OS, 59802 available.
4210 - fixup consistency of port_if out array during heavy use.
4212 10 April 2008: Wouter

4214 - added log file statistics perl script to contrib.
4215 - automatic iana ports update from makefile. 60058 available.
4217 9 April 2008: Wouter
4218 - configure can detect libev(from its build directory) when passed
4219 --with-libevent=/home/wouter/libev-3.2
4220 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
4221 - unused commpoints not listed in epoll list.
4222 - statistics-cumulative option so that the values are not reset.
4223 - config creates array of available ports, 61841 available,
4224 it excludes <1024 and iana assigned numbers.
4225 config statements to modify the available port numbers.
4227 8 April 2008: Wouter
4228 - unbound tries to set the ulimit fds when started as server.
4229 if that does not work, it will scale back its requirements.
4231 27 March 2008: Wouter
4232 - documented /dev/random symlink from chrootdir as FAQ entry.
4234 26 March 2008: Wouter
4235 - implemented AD bit signaling. If a query sets AD bit (but not DO)
4236 then the AD bit is set in the reply if the answer validated.
4237 Without including DNSSEC signatures. Useful if you have a trusted
4238 path from the client to the resolver. Follows dnssec-updates draft.
4240 25 March 2008: Wouter
4241 - implemented check that for NXDOMAIN and NOERROR answers a query
4242 section must be present in the reply (by the scrubber). And it must
4243 be equal to the question sent, at least lowercase folded.
4244 Previously this feature happened because the cache code refused
4245 to store such messages. However blocking by the scrubber makes
4246 sure nothing gets into the RRset cache. Also, this looks like a
4247 timeout (instead of an allocation failure) and this retries are
4248 done (which is useful in a spoofing situation).
4249 - RTT banding. Band size 400 msec, this makes band around zero (fast)
4250 include unknown servers. This makes unbound explore unknown servers.
4252 7 March 2008: Wouter
4253 - -C config feature for harvest program.
4254 - harvest handles CNAMEs too.
4256 5 March 2008: Wouter
4257 - patch from Hugo Koji Kobayashi for iterator logs spelling.
4259 4 March 2008: Wouter
4260 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
4261 of a cname trust chain is lower; not full answer_AA.
4262 - test for this fix.
4263 - default config file location is /usr/local/etc/unbound.
4264 Thus prefix is used to determine the location. This is also the
4265 chroot and pidfile default location.
4267 3 March 2008: Wouter
4268 - Create 0.10 svn tag.
4269 - 0.11 version in trunk.
4270 - indentation nicer.
4272 29 February 2008: Wouter
4273 - documentation update.
4274 - fixup port to Solaris of perf test tool.
4275 - updated ldns-tarball with decl-after-statement fixes.

4279 - libunbound returns the answer packet in full.
4280 - snprintf compat update.
4281 - harvest performs lookup.
4282 - ldns-tarball update with fix for ldns_dname_label.
4283 - installs to sbin by default.
4284 - install all manual pages (unbound-host and libunbound too).
4286 27 February 2008: Wouter
4287 - option to use caps for id randomness.
4288 - config file option use-caps-for-id: yes
4289 - harvest debug tool
4291 26 February 2008: Wouter
4292 - delay utility delays TCP as well. If the server that is forwarded
4293 to has a TCP error, the delay utility closes the connection.
4294 - delay does REUSE_ADDR, and can handle a server that closes its end.
4295 - answers use casing from query.
4297 25 February 2008: Wouter
4298 - delay utility works. Gets decent thoughput too (>20000).
4300 22 February 2008: Wouter
4301 - +2% for recursions, if identical queries (except for destination
4302 and query ID) in the reply list, avoid re-encoding the answer.
4303 - removed TODO items for optimizations that do not show up in
4305 - default is now minievent - not libevent. As its faster and
4306 not needed for regular installs, only for very large port ranges.
4307 - loop check different speedup pkt-dname-reading, 1% faster for
4308 nocache-recursion check.
4309 - less hashing during msg parse, 4% for recursion.
4310 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
4311 - some speed results noted:
4312 optimization resulted in +40% for recursion (cache miss) and
4313 +70 to +80 for cache hits, and +96% for version.bind.
4314 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
4315 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
4316 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
4317 So, unbound can be about equal qps to NSD in cache hits.
4318 And about 3.4x faster than BIND in cache performance.
4319 - delay utility for testing.
4321 21 February 2008: Wouter
4322 - speedup of root-delegation message encoding by 15%.
4323 - minor speedup of compress tree_lookup, maybe 1%.
4324 - speedup of dname_lab_cmp and memlowercmp - the top functions in
4325 profiler output, maybe a couple percent when it matters.
4327 20 February 2008: Wouter
4328 - setup speec_cache for need-ldns-testns in dotests.
4329 - check number of queued replies on incoming queries to avoid overload
4331 - fptr whitelist checks are not disabled in optimize mode.
4332 - do-daemonize config file option.
4333 - minievent time share initializes time at start.
4334 - updated testdata for nsec3 new algorithm numbers (6, 7).
4335 - small performance test of packet encoding (root delegation).
4337 19 February 2008: Wouter
4338 - applied patch to unbound-host man page from Jan-Piet Mens.
4339 - fix donotquery-localhost: yes default (it erroneously was switched
4341 - time is only gotten once and the value is shared across unbound.
4342 - unittest cleans up crypto, so that it has no memory leaks.
4343 - mini_event shares the time value with unbound this results in
4344 +3% speed for cache responses and +9% for recursions.
4345 - ldns tarball update with new NSEC3 sign code numbers.
4346 - perform several reads per UDP operation. This improves performance
4347 in DoS conditions, and costs very little in normal conditions.
4348 improves cache response +50%, and recursions +10%.
4349 - modified asynclook test. because the callback from async is not
4350 in any sort of lock (and thus can use all library functions freely),
4351 this causes a tiny race condition window when the last lock is
4352 released for a callback and a new cancel() for that callback.
4353 The only way to remove this is by putting callbacks into some
4354 lock window. I'd rather have the small possibility of a callback
4355 for a cancelled function then no use of library functions in
4356 callbacks. Could be possible to only outlaw process(), wait(),
4357 cancel() from callbacks, by adding another lock, but I'd rather not.
4359 18 February 2008: Wouter
4360 - patch to unbound-host from Jan-Piet Mens.
4361 - unbound host prints errors if fails to configure context.
4362 - fixup perf to resend faster, so that long waiting requests do
4363 not hold up the queue, they become lost packets or SERVFAILs,
4364 or can be sent a little while later (i.e. processing time may
4365 take long, but throughput has to be high).
4366 - fixup iterator operating in no cache conditions (RD flag unset
4368 - streamlined code for RD flag setting.
4369 - profiled code and changed dname compares to be faster.
4370 The speedup is about +3% to +8% (depending on the test).
4371 - minievent tests for eintr and eagain.
4373 15 February 2008: Wouter
4374 - added FreeBSD rc.d script to contrib.
4375 - --prefix option for configure also changes directory: pidfile:
4376 and chroot: defaults in config file.
4377 - added cache speed test, for cache size OK and cache too small.
4379 14 February 2008: Wouter
4380 - start without a config file (will complain, but start with
4382 - perf test program works.

4404 - unbound replies to multiple TCP queries on a TCP channel.
4405 - fixup misclassification of root referral with NS in answer
4406 when validating a nonrec query.
4408 - layout of manpages, spelling fix in header, manpages process by
4409 makedist, list asynclook and tcpstream tests as ldns-testns
4412 7 February 2008: Wouter
4413 - moved up all current level 2 to be level 3. And 3 to 4.
4414 to make room for new debug level 2 for detailed information
4416 - verbosity level 2. Describes recursion and validation.
4417 - cleaner configure script and fixes for libevent solaris.
4418 - signedness for log output memory sizes in high verbosity.
4420 6 February 2008: Wouter
4421 - clearer explanation of threading configure options.
4422 - fixup asynclook test for nothreading (it creates only one process
4423 to do the extended test).
4424 - changed name of ub_val_result_free to ub_val_resolve_free.
4425 - removes warning message during library linking, renamed
4426 libunbound/unbound.c -> libunbound.c and worker to libworker.

4435 31 January 2008: Wouter
4436 - bg thread/process reads and writes the pipe nonblocking all the time
4437 so that even if the pipe is buffered or so, the bg thread does not
4438 block, and services both pipes and queries.
4440 30 January 2008: Wouter
4441 - check trailing / on chrootdir in checkconf.
4442 - check if root hints and anchor files are in chrootdir.

4451 - fixup uninit warning from random.c; also seems to fix sporadic
4452 sigFPE coming out of openssl.
4453 - made openssl entropy warning more silent for library use. Needs
4455 - fixup forgotten locks for rbtree_searches on ctx->query tree.
4456 - random generator cleanup - RND_STATE_SIZE removed, and instead
4457 a super-rnd can be passed at init to chain init random states.
4458 - test also does lock checks if available.
4459 - protect config access in libworker_setup().
4460 - libevent doesn't like comm_base_exit outside of runloop.
4461 - close fds after removing commpoints only (for epoll, kqueue).
4463 25 January 2008: Wouter
4464 - added tpkg for asynclook and library use.
4465 - allows localhost to be queried when as a library.
4466 - fixup race condition between cancel and answer (in case of
4467 really fast answers that beat the cancel).
4468 - please doxygen, put doxygen comment in one place.
4469 - asynclook -b blocking mode and test.
4470 - refactor asynclook, nicer code.
4471 - fixup race problems from opensll in rand init from library, with
4472 a mutex around the rand init.
4473 - fix pass async_id=NULL to _async resolve().
4474 - rewrote _wait() routine, so that it is threadsafe.
4475 - cancelation is threadsafe.
4476 - asynclook extended test in tpkg.
4477 - fixed two races where forked bg process waits for (somehow shared?)
4478 locks, so does not service the query pipe on the bg side.
4479 Now those locks are only held for fg_threads and for bg_as_a_thread.
4481 24 January 2008: Wouter
4482 - tested the cancel() function.
4483 - asynclook -c (cancel) feature.

4487 - fix Makefile for concurrent make of unbound-host.
4488 - renamed ub_val_ctx_wait/poll/process/fd to ub_val*.
4489 - new calls to set forwarding added to header and docs.
4491 23 January 2008: Wouter
4492 - removed debug prints from if-auto, verb-algo enables some.
4493 - libunbound QUIT setup, remove memory leaks, when using threads
4494 will share memory for passing results instead of writing it over
4495 the pipe, only writes ID number over the pipe (towards the handler
4496 thread that does process() ).
4498 22 January 2008: Wouter
4499 - library code for async in libunbound/unbound.c.
4500 - fix link testbound.
4501 - fixup exit bug in mini_event.
4502 - background worker query enter and result functions.
4503 - bg query test application asynclook, it looks up multiple
4504 hostaddresses (A records) at the same time.
4506 21 January 2008: Wouter
4507 - libworker work, netevent raw commpoints, write_msg, serialize.
4509 18 January 2008: Wouter
4510 - touch up of manpage for libunbound.
4511 - support for IP_RECVDSTADDR (for *BSD ip4).
4512 - fix for BSD, do not use ip4to6 mapping, make two sockets, once
4513 ip6 and once ip4, uses socket options.
4514 - goodbye ip4to6 mapping.
4515 - update ldns-testpkts with latest version from ldns-trunk.
4516 - updated makedist for relative ldns pathnames.
4517 - library API with more information inside the result structure.
4518 - work on background resolves.
4520 17 January 2008: Wouter
4521 - fixup configure in case -lldns is installed.
4522 - fixup a couple of doxygen warnings, about enum variables.
4523 - interface-automatic now copies the interface address from the
4524 PKT_INFO structure as well.
4525 - manual page with library API, all on one page 'man libunbound'.
4526 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
4528 16 January 2008: Wouter
4529 - incoming queries to the server with TC bit on are replied FORMERR.
4530 - interface-automatic replied the wrong source address on localhost
4531 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
4532 to use ifnum=-1 to mean 'no interface, use kernel route'.
4534 15 January 2008: Wouter
4535 - interface-automatic feature. experimental. Nice for anycast.
4536 - tpkg test for ip6 ancillary data.
4537 - removed debug prints.
4538 - porting experience, define for Solaris, test refined for BSD
4539 compatibility. The feature probably will not work on OpenBSD.
4540 - makedist fixup for ldns-src in build-dir.
4542 14 January 2008: Wouter
4543 - in no debug sets NDEBUG to remove asserts.
4544 - configure --enable-debug is needed for dependency generation
4545 for assertions and for compiler warnings.
4546 - ldns.tgz updated with ldns-trunk (where buffer.h is updated).
4547 - fix lint, unit test in optimize mode.
4548 - default access control allows ::ffff:127.0.0.1 v6mapped localhost.
4550 11 January 2008: Wouter
4551 - man page, warning removed.
4552 - added text describing the use of stub zones for private zones.
4553 - checkconf tests for bad hostnames (IP address), and for doubled
4555 - memory sizes can be given with 'k', 'Kb', or M or G appended.
4557 10 January 2008: Wouter
4558 - typo in example.conf.
4559 - made using ldns-src that is included the package more portable
4560 by linking with .lo instead of .o files in the ldns package.
4561 - nicer do-ip6: yes/no documentation.
4562 - nicer linking of libevent .o files.
4563 - man pages render correctly on solaris.
4565 9 January 2008: Wouter
4566 - fixup openssl RAND problem, when the system is not configured to
4567 give entropy, and the rng needs to be seeded.
4569 8 January 2008: Wouter
4570 - print median and quartiles with extensive logging.
4572 4 January 2008: Wouter
4573 - document misconfiguration in private network.
4575 2 January 2008: Wouter
4576 - fixup typo in requirements.
4577 - document that 'refused' is a better choice than 'drop' for
4578 the access control list, as refused will stop retries.
4580 7 December 2007: Wouter
4581 - unbound-host has a -d option to show what happens. This can help
4582 with debugging (why do I get this answer).
4583 - fixup CNAME handling, on nodata, sets and display canonname.
4584 - dot removed from CNAME display.
4585 - respect -v for NXDOMAINs.
4586 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
4587 - size_t to int for portability of the header file.
4588 - fixup bogus handling.
4589 - dependencies and lint for unbound-host.
4591 6 December 2007: Wouter
4592 - library resolution works in foreground mode, unbound-host app
4594 - unbound-host prints rdata using ldns.
4595 - unbound-host accepts trust anchors, and prints validation
4596 information when you give -v.
4598 5 December 2007: Wouter
4599 - locking in context_new() inside the function.
4600 - setup of libworker.
4602 4 December 2007: Wouter
4603 - minor Makefile fixup.
4604 - moved module-stack code out of daemon/daemon into services/modstack,
4605 preparing for code-reuse.
4606 - move context into own header file.
4607 - context query structure.
4608 - removed unused variable pwd from checkconf.
4609 - removed unused assignment from outside netw.
4610 - check timeval length of string.
4611 - fixup error in val_utils getsigner.

4613 - fixup memleak on parse error in localzone.
4614 - fixup memleak on packet parse error.
4615 - put ; after union in parser.y.
4616 - small hardening in iter_operate against iq==NULL.
4617 - hardening, if error reply with rcode=0 (noerror) send servfail.
4618 - fixup same (*var) error in find_rrset in msgparse, was harmless.
4619 - check return value of evtimer_add().
4620 - fixup lockorder in lruhash_reclaim(), building up a list of locked
4621 entries one at a time. Instead they are removed and unlocked.
4622 - fptr_wlist for markdelfunc.
4623 - removed is_locked param from lruhash delkeyfunc.
4624 - moved bin_unlock during bin_split purely to please.
4626 3 December 2007: Wouter
4627 - changed checkconf/ to smallapp/ to make room for more support tools.
4628 (such as unbound-host).
4629 - install dirs created with -m 755 because they need to be accessible.
4630 - library extensive featurelist added to TODO.
4631 - please doxygen, lint.
4632 - library test application, with basic functionality.
4633 - fix for building in a subdirectory.
4634 - link lib fix for Leopard.
4636 30 November 2007: Wouter
4637 - makefile that creates libunbound.la, basic file or libunbound.a
4638 when creating static executables (no libtool).
4641 29 November 2007: Wouter
4642 - 0.9 public API start.
4644 28 November 2007: Wouter
4645 - Changeup plan for 0.8 - no complication needed, a simple solution
4646 has been chosen for authoritative features.
4647 - you can use single quotes in the config file, so it is possible
4648 to specify TXT records in local data.
4649 - fixup small memory problem in implicit transparent zone creation.
4650 - test for implicit zone creation and multiple RR RRsets local data.
4651 - local-zone nodefault test.
4652 - show testbound testlist on commit.
4653 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
4654 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
4656 - nicer verbosity: 0 and 1 levels.
4657 - lower nonRDquery chance of eliciting wrongly typed validation
4658 requiring message from the cache.
4659 - fix for nonRDquery validation typing; nodata is detected when
4660 SOA record in auth section (all validation-requiring nodata messages
4661 have a SOA record in authority, so this is OK for the validator),
4662 and NS record is needed to be a referral.
4663 - duplicate checking when adding NSECs for a CNAME, and test.
4664 - created svn tag 0.8, after completing testbed tests.
4666 27 November 2007: Wouter
4667 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
4668 - set size of msgparse lookup table to 32, from 1024, so that its size
4669 is below the 2048 regional large size threshold, and does not cause
4670 a call to malloc when a message is parsed.
4671 - update of memstats tool to print number of allocation calls.
4672 This is what is taking time (not space) and indicates the avg size
4673 of the allocations as well. region_alloc stat is removed.
4675 22 November 2007: Wouter
4676 - noted EDNS in-the-middle dropping trouble as a TODO.
4677 At this point theoretical, no user trouble has been reported.
4678 - added all default AS112 zones.
4679 - answers from local zone content.
4680 * positive answer, the rrset in question
4681 * nodata answer (exist, but not that type).
4682 * nxdomain answer (domain does not exist).
4683 * empty-nonterminal answer.
4684 * But not: wildcard, nsec, referral, rrsig, cname/dname,
4685 or additional section processing, NS put in auth.
4686 - test for correct working of static and transparent and couple
4687 of important defaults (localhost, as112, reverses).
4688 Also checks deny and refuse settings.
4689 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
4691 21 November 2007: Wouter
4692 - local zone internal data setup.
4694 20 November 2007: Wouter
4695 - 0.8 - str2list config support for double string config options.
4696 - local-zone and local-data options, config storage and documentation.
4698 19 November 2007: Wouter
4699 - do not downcase NSEC and RRSIG for verification. Follows
4700 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
4701 - fixup leaking unbound daemons at end of tests.
4702 - README file updated.
4703 - nice libevent not found error.
4704 - README talks about gnu make.
4705 - 0.8: unit test for addr_mask and fixups for it.
4706 and unit test for addr_in_common().
4707 - 0.8: access-control config file element.
4708 and unit test rpl replay file.
4709 - 0.8: fixup address reporting from netevent.
4711 16 November 2007: Wouter
4712 - privilege separation is not needed in unbound at this time.
4713 TODO item marked as such.
4714 - created beta-0.7 branch for support.
4715 - tagged 0.7 for beta release.
4716 - moved trunk to 0.8 for 0.8(auth features) development.
4717 - 0.8: access control list setup.
4719 15 November 2007: Wouter
4720 - review fixups from Jelte.
4722 14 November 2007: Wouter
4723 - testbed script does not recreate configure, since its in svn now.
4724 - fixup checkconf test so that it does not test
4725 /etc/unbound/unbound.conf.
4728 13 November 2007: Wouter
4729 - remove debug print.
4730 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
4732 12 November 2007: Wouter
4733 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
4735 - bugreports to unbound-bugs@nlnetlabs.nl
4736 - fixup testbound so it exits cleanly.
4737 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
4739 9 November 2007: Wouter
4740 - took ldns snapshot in repo.
4741 - default config file is /etc/unbound/unbound.conf.
4742 If it doesn't exist, it is installed with the doc/example.conf file.
4743 The file is not deleted on uninstall.
4744 - default listening is not all, but localhost interfaces.
4746 8 November 2007: Wouter
4747 - Fixup chroot and drop user privileges.
4748 - new L root ip address in default hints.
4750 1 November 2007: Wouter
4751 - Fixup of crash on reload, due to anchors in env not NULLed after
4752 dealloc during deinit.
4753 - Fixup of chroot call. Happens after privileges are dropped, so
4754 that checking the passwd entry still works.
4755 - minor touch up of clear() hashtable function.
4756 - VERB_DETAIL prints out what chdir, username, chroot is being done.
4757 - when id numbers run out, caches are cleared, as in design notes.
4758 Tested with a mock setup with very few bits in id, it worked.
4759 - harden-dnssec-stripped: yes is now default. It insists on dnssec
4760 data for trust anchors. Included tests for the feature.
4762 31 October 2007: Wouter
4763 - cache-max-ttl config option.
4764 - building outside sourcedir works again.
4765 - defaults more secure:
4767 chroot: "/etc/unbound"
4768 The operator can override them to be less secure ("") if necessary.
4769 - fix horrible oversight in sorting rrset references in a message,
4770 sort per reference key pointer, not on referencepointer itself.
4771 - pidfile: "/etc/unbound/unbound.pid" is now the default.
4772 - tests changed to reflect the updated default.
4773 - created hashtable clear() function that respects locks.
4775 30 October 2007: Wouter
4776 - fixup assertion failure that relied on compressed names to be
4777 smaller than uncompressed names. A packet from comrite.com was seen
4778 to be compressed to a larger size. Added it as unit test.
4779 - quieter logging at low verbosity level for common tcp messages.
4780 - no greedy TTL update.
4782 23 October 2007: Wouter
4783 - fixup (grand-)parent problem for dnssec-lameness detection.
4784 - fixup tests to do additional section processing for lame replies,
4785 since the detection needs that.
4786 - no longer trust in query section in reply during dnssec lame detect.
4787 - dnssec lameness does not make the server never ever queried, but
4788 non-preferred. If no other servers exist or answer, the dnssec lame
4789 server is used; the fastest dnssec lame server is chosen.
4790 - added test then when trust anchor cannot be primed (nodata), the
4791 insecure mode from unbound works.
4792 - Fixup max queries per thread, any more are dropped.
4794 22 October 2007: Wouter
4795 - added donotquerylocalhost config option. Can be turned off for
4797 - ISO C compat changes.
4798 - detect RA-no-AA lameness, as LAME.
4799 - DNSSEC-lameness detection, as LAME.
4800 See notes in requirements.txt for choices made.
4801 - tests for lameness detection.
4802 - added all to make test target; need unbound for fwd tests.
4803 - testbound does not pollute /etc/unbound.
4805 19 October 2007: Wouter
4806 - added configure (and its files) to svn, so that the trunk is easier
4807 to use. ./configure, config.guess, config.sub, ltmain.sh,
4809 - added yacc/lex generated files, util/configlexer.c,
4810 util/configparser.c util/configparser.h, to svn.
4811 - without lex no attempt to use it.
4812 - unsecure response validation collated into one block.
4813 - remove warning about const cast of cfgfile name.
4814 - outgoing-interfaces can be different from service interfaces.
4815 - ldns-src configure is done during unbound configure and
4816 ldns-src make is done during unbound make, and so inherits the
4817 make arguments from the unbound make invocation.
4818 - nicer error when libevent problem causes instant exit on signal.
4819 - read root hints from a root hint file (like BIND does).
4821 18 October 2007: Wouter
4822 - addresses are logged with errors.
4823 - fixup testcode fake event to remove pending before callback
4824 since the callback may create new pending items.
4825 - tests updated because retries are now in iterator module.
4826 - ldns-testpkts code is checked for differences between unbound
4827 and ldns by makedist.sh.
4828 - ldns trunk from today added in svn repo for fallback in case
4829 no ldns is installed on the system.
4830 make download_ldns refreshes the tarball with ldns svn trunk.
4831 - ldns-src.tar.gz is used if no ldns is found on the system, and
4832 statically linked into unbound.
4833 - start of regional allocator code.
4834 - regional uses less memory and variables, simplified code.
4835 - remove of region-allocator.
4836 - alloc cache keeps a cache of recently released regional blocks,
4838 - make unit test cleanly free memory.
4840 17 October 2007: Wouter
4841 - fixup another cycle detect and ns-addr timeout resolution bug.
4842 This time by refusing delegations from the cache without addresses
4843 when resolving a mandatory-glue nameserver-address for that zone.
4844 We're going to have to ask a TLD server anyway; might as well be
4845 the TLD server for this name. And this resolves a lot of cases where
4846 the other nameserver names lead to cycles or are not available.
4847 - changed random generator from random(3) clone to arc4random wrapped
4848 for thread safety. The random generator is initialised with
4849 entropy from the system.
4850 - fix crash where failure to prime DNSKEY tried to print null pointer
4852 - removed some debug prints, only verb_algo (4) enables them.
4853 - fixup test; new random generator took new paths; such as one
4854 where no scripted answer was available.
4855 - mark insecure RRs as insecure.
4856 - fixup removal of nonsecure items from the additional.
4857 - reduced timeout values to more realistic, 376 msec (262 msec has
4858 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
4859 - server selection failover to next server after timeout (376 msec).
4861 16 October 2007: Wouter
4862 - no malloc in log_hex.
4863 - assertions around system calls.
4864 - protect against gethostname without ending zero.
4865 - ntop output is null terminated by unbound.
4866 - pidfile content null termination
4867 - various snprintf use sizeof(stringbuf) instead of fixed constant.
4868 - changed loopdetect % 8 with & 0x7 since % can become negative for
4869 weird negative input and particular interpretation of integer math.
4870 - dname_pkt_copy checks length of result, to protect result buffers.
4871 prints an error, this should not happen. Bad strings should have
4872 been rejected earlier in the program.
4873 - remove a size_t underflow from msgreply size func.
4875 15 October 2007: Wouter
4877 - fix IP6 TCP, wrong definition check. With test package.
4878 - fixup the fact that the query section was not compressed to,
4879 the code was there but was called by value instead of by reference.
4880 And test for the case, uses xxd and nc.
4881 - more portable ip6 check for sockaddr types.
4883 8 October 2007: Wouter
4884 - --disable-rpath option in configure for 64bit systems with
4885 several dynamic lib dirs.
4887 7 October 2007: Wouter
4888 - fixup tests for no AD bit in non-DO queries.
4889 - test that makes sure AD bit is not set on non-DO query.
4891 6 October 2007: Wouter
4892 - removed logfile open early. It did not have the proper permissions;
4893 it was opened as root instead of the user. And we cannot change user
4894 id yet, since chroot and bind ports need to be done.
4895 - callback checks for event callbacks done from mini_event. Because
4896 of deletions cannot do this from netevent. This means when using
4897 libevent the protection does not work on event-callbacks.
4898 - fixup too small reply (did not zero counts).
4899 - fixup reply no longer AD bit when query without DO bit.
4901 5 October 2007: Wouter
4902 - function pointer whitelist.
4904 4 October 2007: Wouter
4905 - overwrite sensitive random seed value after use.
4906 - switch to logfile very soon if not -d (console attached).
4907 - error messages do not reveal the trustanchor contents.
4908 - start work on function pointer whitelists.
4910 3 October 2007: Wouter
4911 - fix for multiple empty nonterminals, after multiple DSes in the
4913 - mesh checks if modules are looping, and stops them.
4914 - refetch with CNAMEd nameserver address regression test added.
4915 - fixup line count bug in testcode, so testbound prints correct line
4916 number with parse errors.
4917 - unit test for multiple ENT case.
4918 - fix for cname out of validated unsec zone.
4919 - fixup nasty id=0 reuse. Also added assertions to detect its
4920 return (the assertion catches in the existing test cases).
4922 1 October 2007: Wouter
4923 - skip F77, CXX, objC tests in configure step.
4924 - fixup crash in refetch glue after a CNAME.
4925 and protection against similar failures (with error print).
4927 28 September 2007: Wouter
4928 - test case for unbound-checkconf, fixed so it also checks the
4929 interface: statements.
4931 26 September 2007: Wouter
4932 - SIGHUP will reopen the log file.
4933 - Option to log to syslog.
4934 - please lint, fixup tests (that went to syslog on open, oops).
4935 - config check program.
4937 25 September 2007: Wouter
4938 - tests for NSEC3. Fixup bitmap checks for NSEC3.
4939 - positive ANY response needs to check if wildcard expansion, and
4940 check that original data did not exist.
4941 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
4942 delegation, for abuse of child zone apex nsec3.
4943 - create 0.5 release tag.
4945 24 September 2007: Wouter
4946 - do not make test programs by default.
4947 - But 'make test' will perform all of the tests.
4948 - Advertise builtin select libevent alternative when no libevent
4950 - signit can generate NSEC3 hashes, for generating tests.
4951 - multiple nsec3 paramaters in message test.
4952 - too high nsec3 iterations becomes insecure test.
4954 21 September 2007: Wouter
4955 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
4956 - fixup testcode lock safety (port FreeBSD).
4957 - removes subscript has type char warnings (port Solaris 9).
4958 - fixup of field with format type to int (port MacOS/X intel).
4959 - added test for infinite loop case in nonRD answer validation.
4960 It was a more general problem, but hard to reproduce. When an
4961 unsigned rrset is being validated and the key fetched, the DS
4962 sequence is followed, but if the final name has no DS, then no
4963 proof is possible - the signature has been stripped off.
4965 20 September 2007: Wouter
4966 - fixup and test for NSEC wildcard with empty nonterminals.
4967 - makedist.sh fixup for svn info.
4968 - acl features request in plan.
4969 - improved DS empty nonterminal handling.
4970 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
4971 proof anyway, which succeeds in ANS failure case.
4972 - striplab protection in case it becomes -1.
4973 - plans for static and blacklist config.
4975 19 September 2007: Wouter
4976 - comments about non-packed usage.
4977 - plan for overload support in 0.6.
4978 - added testbound tests for a failed resolution from the logs
4979 and for failed prime when missing glue.
4980 - fixup so useless delegation points are not returned from the
4981 cache. Also the safety belt is used if priming fails to complete.
4982 - fixup NSEC rdata not to be lowercased, bind compat.
4984 18 September 2007: Wouter
4985 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
4986 - validator prints subtype classification for debug.
4988 17 September 2007: Wouter
4989 - NSEC3 hash cache unit test.
4990 - validator nsec3 nameerror test.
4992 14 September 2007: Wouter
4993 - nsec3 nodata proof, nods proof, wildcard proof.
4994 - nsec3 support for cname chain ending in noerror or nodata.
4995 - validator calls nsec3 proof routines if no NSECs prove anything.
4996 - fixup iterator bug where it stored the answer to a cname under
4997 the wrong qname into the cache. When prepending the cnames, the
4998 qname has to be reset to the original qname.
5000 13 September 2007: Wouter
5001 - nsec3 find matching and covering, ce proof, prove namerror msg.
5003 12 September 2007: Wouter
5004 - fixup of manual page warnings, like for NSD bugreport.
5005 - nsec3 work, config, max iterations, filter, and hash cache.
5007 6 September 2007: Wouter
5008 - fixup to find libevent on mac port install.
5009 - fixup size_t vs unsigned portability in validator/sigcrypt.
5010 - please compiler on different platforms, for unreachable code.
5012 - pthread_rwlock type is optional, in case of old pthread libs.
5014 5 September 2007: Wouter
5015 - cname, name error validator tests.
5016 - logging of qtype ANY works.
5017 - ANY type answers get RRSIG in answer section of replies (but not
5018 in other sections, unless DO bit is on).
5019 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
5020 - DS and noDS referral validation test.
5021 - if you configure many trust anchors, parent trust anchors can
5022 securely deny existance of child trust anchors, if validated.
5023 - not all *.name NSECs are present because a wildcard was matched,
5024 and *.name NSECs can prove nodata for empty nonterminals.
5025 Also, for wildcard name NSECs, check they are not from the parent
5026 zone (for wildcarded zone cuts), and check absence of CNAME bit,
5028 - configure option for memory allocation debugging.
5029 - port configure option for memory allocation to solaris10.
5031 4 September 2007: Wouter
5032 - fixup of Leakage warning when serviced queries processed multiple
5033 callbacks for the same query from the same server.
5034 - testbound removes config file from /tmp on failed exit.
5035 - fixup for referral cleanup of the additional section.
5036 - tests for cname, referral validation.
5037 - neater testbound tpkg output.
5038 - DNAMEs no longer match their apex when synthesized from the cache.
5039 - find correct signer name for DNAME responses.
5040 - wildcarded DNAME test and fixup code to detect.
5041 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
5042 So that wildcarded CNAMEs get their NSEC with them to the answer.
5043 - test for a CNAME to a DNAME to a CNAME to an answer, all from
5044 different domains, for key fetching and signature checking of
5047 3 September 2007: Wouter
5048 - Fixed error in iterator that would cause assertion failure in
5049 validator. CNAME to a NXDOMAIN response was collated into a response
5050 with both a CNAME and the NXDOMAIN rcode. Added a test that the
5051 rcode is changed to NOERROR (because of the CNAME).
5052 - timeout on tcp does not lead to spurious leakage detect.
5053 - account memory for name of lame zones, so that memory leakages does
5054 not show lame cache growth as a leakage growth.
5055 - config setting for lameness cache expressed in bytes, instead of
5057 - tool too summarize allocations per code line.
5059 31 August 2007: Wouter
5060 - can read bind trusted-keys { ... }; files, in a compatibility mode.
5061 - iterator should not detach target queries that it still could need.
5062 the protection against multiple outstanding queries is moved to a
5063 current_query num check.
5064 - validator nodata, positive, referral tests.
5065 - dname print can print '*' wildcard.
5067 30 August 2007: Wouter
5068 - fixup override date config option.
5069 - config options to control memory usage.
5070 - caught bad free of un-alloced data in worker_send error case.
5071 - memory accounting for key cache (trust anchors and temporary cache).
5072 - memory accounting fixup for outside network tcp pending waits.
5073 - memory accounting fixup for outside network tcp callbacks.
5074 - memory accounting for iterator fixed storage.
5075 - key cache size and slabs config options.
5076 - lib crypto cleanups at exit.
5078 29 August 2007: Wouter
5079 - test tool to sign rrsets for testing validator with.
5080 - added RSA and DSA test keys, public and private pairs, 512 bits.
5081 - default configuration is with validation enabled.
5082 Only a trust-anchor needs to be configured for DNSSEC to work.
5083 - do not convert to DER for DSA signature verification.
5084 - validator replay test file, for a DS to DNSKEY DSA key prime and
5087 28 August 2007: Wouter
5088 - removed double use for udp buffers, that could fail,
5089 instead performs a malloc to do the backup.
5090 - validator validates referral messages, by validating all the rrsets
5091 and stores the rrsets in the cache. Further referral (nonRD queries)
5092 replies are made from the rrset cache directly. Unless unchecked
5093 rrsets are encountered, there are then validated.
5094 - enforce that signing is done by a parent domain (or same domain).
5095 - adjust TTL downwards if rrset TTL bigger than signature allows.
5096 - permissive mode feature, sets AD bit for secure, but bogus does
5097 not give servfail (bogus is changed into indeterminate).
5098 - optimization of rrset verification. rr canonical sorting is reused,
5099 for the same rrset. canonical rrset image in buffer is reused for
5101 - if the rrset is too big (64k exactly + large owner name) the
5102 canonicalization routine will fail if it does not fit in buffer.
5103 - faster verification for large sigsets.
5104 - verb_detail mode reports validation failures, but not the entire
5105 algorithm for validation. Key prime failures are reported as
5108 27 August 2007: Wouter
5109 - do not garble the edns if a cache answer fails.
5110 - answer norecursive from cache if possible.
5111 - honor clean_additional setting when returning secure non-recursive
5113 - do not store referral in msg cache for nonRD queries.
5114 - store verification status in the rrset cache to speed up future
5116 - mark rrsets indeterminate and insecure if they are found to be so.
5117 and store this in the cache.
5119 24 August 2007: Wouter
5120 - message is bogus if unsecure authority rrsets are present.
5121 - val-clean-additional option, so you can turn it off.
5122 - move rrset verification out of the specific proof types into one
5123 routine. This makes the proof routines prettier.
5124 - fixup cname handling in validator, cname-to-positive and cname-to-
5126 - Do not synthesize DNSKEY and DS responses from the rrset cache if
5127 the rrset is from the additional section. Signatures may have
5128 fallen off the packet, and cause validation failure.
5129 - more verbose signature date errors (with the date attached).
5130 - increased default infrastructure cache size. It is important for
5131 performance, and 1000 entries are only 212k (or a 400 k total cache
5132 size). To 10000 entries (for 2M entries, 4M cache size).
5134 23 August 2007: Wouter
5135 - CNAME handling - move needs_validation to before val_new().
5136 val_new() setups the chase-reply to be an edited copy of the msg.
5137 new classification, and find signer can find for it.
5138 removal of unsigned crap from additional, and query restart for
5140 - refuse to follow wildcarded DNAMEs when validating.
5141 But you can query for qtype ANY, or qtype DNAME and validate that.
5143 22 August 2007: Wouter
5145 - review - use val_error().
5147 21 August 2007: Wouter
5148 - ANY response validation.
5149 - store security status in cache.
5150 - check cache security status and either send the query to be
5151 validated, return the query to client, or send servfail to client.
5152 Sets AD bit on validated replies.
5153 - do not examine security status on an error reply in mesh_done.
5154 - construct DS, DNSKEY messages from rrset cache.
5155 - manual page entry for override-date.
5157 20 August 2007: Wouter
5158 - validate and positive validation, positive wildcard NSEC validation.
5159 - nodata validation, nxdomain validation.
5161 18 August 2007: Wouter
5162 - process DNSKEY response in FINDKEY state.
5164 17 August 2007: Wouter
5165 - work on DS2KE routine.
5166 - val_nsec.c for validator NSEC proofs.
5167 - unit test for NSEC bitmap reading.
5168 - dname iswild and canonical_compare with unit tests.
5170 16 August 2007: Wouter
5172 - latest release libevent 1.3c and 1.3d have threading fixed.
5173 - key entry fixup data pointer and ttl absolute.
5174 - This makes a key-prime succeed in validator, with DS or DNSKEY as
5176 - fixup canonical compare byfield routine, fix bug and also neater.
5177 - fixed iterator response type classification for queries of type
5179 dig ANY gives sometimes NS rrset in AN and NS section, and parser
5180 removes the NS section duplicate. dig NS gives sometimes the NS
5181 in the answer section, as referral.
5182 - validator FINDKEY state.
5184 15 August 2007: Wouter
5185 - crypto calls to verify signatures.
5186 - unit test for rrsig verification.
5188 14 August 2007: Wouter
5189 - default outgoing ports changed to avoid port 2049 by default.
5190 This port is widely blocked by firewalls.
5191 - count infra lameness cache in memory size.
5192 - accounting of memory improved
5193 - outbound entries are allocated in the query region they are for.
5194 - extensive debugging for memory allocations.
5195 - --enable-lock-checks can be used to enable lock checking.
5196 - protect undefs in config.h from autoheaders ministrations.
5197 - print all received udp packets. log hex will print on multiple
5199 - fixed error in parser with backwards rrsig references.
5200 - mark cycle targets for iterator did not have CD flag so failed
5203 13 August 2007: Wouter
5204 - fixup makefile, if lexer is missing give nice error and do not
5205 mess up the dependencies.
5206 - canonical compare routine updated.
5207 - canonical hinfo compare.
5208 - printout list of the queries that the mesh is working on.
5210 10 August 2007: Wouter
5211 - malloc and free overrides that track total allocation and frees.
5212 for memory debugging.
5213 - work on canonical sort.
5215 9 August 2007: Wouter
5216 - canonicalization, signature checks
5217 - dname signature label count and unit test.
5218 - added debug heap size print to memory printout.
5219 - typo fixup in worker.c
5220 - -R needed on solaris.
5221 - validator override option for date check testing.
5223 8 August 2007: Wouter
5224 - ldns _raw routines created (in ldns trunk).
5225 - sigcrypt DS digest routines
5226 - val_utils uses sigcrypt to perform signature cryptography.
5227 - sigcrypt keyset processing
5229 7 August 2007: Wouter
5230 - security status type.
5231 - security status is copied when rdata is equal for rrsets.
5232 - rrset id is updated to invalidate all the message cache entries
5233 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
5235 - val_sigcrypt file for validator signature checks.
5237 6 August 2007: Wouter
5238 - key cache for validator.
5239 - moved isroot and dellabel to own dname routines, with unit test.
5241 3 August 2007: Wouter
5243 - scrubber check section of lame NS set.
5244 - trust anchors can be in config file or read from zone file,
5245 DS and DNSKEY entries.
5246 - unit test trust anchor storage.
5247 - trust anchors converted to packed rrsets.
5248 - key entry definition.
5250 2 August 2007: Wouter
5251 - configure change for latest libevent trunk version (needs -lrt).
5252 - query_done and walk_supers are moved out of module interface.
5253 - fixup delegation point duplicates.
5254 - fixup iterator scrubber; lame NS set is let through the scrubber
5255 so that the classification is lame.
5256 - validator module exists, and does nothing but pass through,
5257 with calling of next module and return.
5260 1 August 2007: Wouter
5261 - set version to 0.5
5262 - module work for module to module interconnections.
5263 - config of modules.
5264 - detect cycle takes flags.
5266 31 July 2007: Wouter
5270 30 July 2007: Wouter
5271 - changed random state init, so that sequential process IDs are not
5272 cancelled out by sequential thread-ids in the random number seed.
5273 - the fwd_three test, which sends three queries to unbound, and
5274 unbound is kept waiting by ldns-testns for 3 seconds, failed
5275 because the retry timeout for default by unbound is 3 seconds too,
5276 it would hit that timeout and fail the test. Changed so that unbound
5277 is kept waiting for 2 seconds instead.
5279 27 July 2007: Wouter
5280 - removed useless -C debug option. It did not work.
5281 - text edit of documentation.
5282 - added doc/CREDITS file, referred to by the manpages.
5285 26 July 2007: Wouter
5286 - cycle detection, for query state dependencies. Will attempt to
5287 circumvent the cycle, but if no other targets available fails.
5288 - unit test for AXFR, IXFR response.
5289 - test for cycle detection.
5291 25 July 2007: Wouter
5292 - testbound read ADDRESS and check it.
5293 - test for version.bind and friends.
5294 - test for iterator chaining through several referrals.
5295 - test and fixup for refetch for glue. Refetch fails if glue
5296 is still not provided.
5298 24 July 2007: Wouter
5299 - Example section in config manual.
5300 - Addr stored for range and moment in replay.
5302 20 July 2007: Wouter
5303 - Check CNAME chain before returning cache entry with CNAMEs.
5304 - Option harden-glue, default is on. It will discard out of zone
5305 data. If disabled, performance is faster, but spoofing attempts
5306 become a possibility. Note that still normalize scrubbing is done,
5307 and that the potentially spoofed data is used for infrastructure
5308 and not returned to the client.
5309 - if glue times out, refetch by asking parent of delegation again.
5310 Much like asking for DS at the parent side.
5311 - TODO items from forgery-resilience draft.
5312 and on memory handling improvements.
5313 - renamed module_event_timeout to module_event_noreply.
5314 - memory reporting code; reports on memory usage after handling
5315 a network packet (not on cache replies).
5317 19 July 2007: Wouter
5318 - shuffle NS selection when getting nameserver target addresses.
5319 - fixup of deadlock warnings, yield cpu in checklock code so that
5320 freebsd scheduler selects correct process to run.
5321 - added identity and version config options and replies.
5322 - store cname messages complete answers.
5324 18 July 2007: Wouter
5325 - do not query addresses, 127.0.0.1, and ::1 by default.
5327 17 July 2007: Wouter
5328 - forward zone options in config file.
5329 - forward per zone in iterator. takes precendence over stubs.
5330 - fixup commithooks.
5331 - removed forward-to and forward-to-port features, subsumed by
5333 - fix parser to handle absent server: clause.
5334 - change untrusted rrset test to account for scrubber that is now
5335 applied during the test (which removes the poison, by the way).
5336 - feature, addresses can be specified with @portnumber, like nsd.conf.
5337 - test config files changed over to new forwarder syntax.
5339 27 June 2007: Wouter
5340 - delete of mesh does a postorder traverse of the tree.
5341 - found and fixed a memory leak. For TTL=0 messages, that would
5342 not be cached, instead the msg-replyinfo structure was leaked.
5343 - changed server selection so it will filter out hosts that are
5344 unresponsive. This is defined as a host with the maximum rto value.
5345 This means that unbound tried the host for retries up to 120 secs.
5346 The rto value will time out after host-ttl seconds from the cache.
5347 This keeps such unresolvable queries from taking up resources.
5348 - utility for keeping histogram.
5350 26 June 2007: Wouter
5351 - mesh is called by worker, and iterator uses it.
5352 This removes the hierarchical code.
5353 QueryTargets state and Finished state are merged for iterator.
5354 - forwarder mode no longer sets AA bit on first reply.
5355 - rcode in walk_supers is not needed.
5357 25 June 2007: Wouter
5359 - error encode routine for ease.
5361 22 June 2007: Wouter
5362 - removed unused _node iterator value from rbtree_t. Takes up space.
5363 - iterator can handle querytargets state without a delegation point
5364 set, so that a priming(stub) subquery error can be handled.
5365 - iterator stores if it is priming or not.
5366 - log_query_info() neater logging.
5367 - changed iterator so that it does not alter module_qstate.qinfo
5368 but keeps a chase query info. Also query_flags are not altered,
5369 the iterator uses chase_flags.
5370 - fixup crash in case no ports for the family exist.
5372 21 June 2007: Wouter
5373 - Fixup secondary buffer in case of error callback.
5374 - cleanup slumber list of runnable states.
5375 - module_subreq_depth fails to work in slumber list.
5376 - fixup query release for cached results to sub targets.
5377 - neater error for tcp connection failure, shows addr in verbose.
5378 - rbtree_init so that it can be used with preallocated memory.
5380 20 June 2007: Wouter
5381 - new -C option to enable coredumps after forking away.
5383 - fixup CNAME generation by scrubber, and memory allocation of it.
5384 - fixup deletion of serviced queries when all callbacks delete too.
5385 - set num target queries to 0 when you move them to slumber list.
5386 - typo in check caused subquery errors to be ignored, fixed.
5387 - make lint happy about rlim_t.
5388 - freeup of modules after freeup of module-states.
5389 - duplicate replies work, this uses secondary udp buffer in outnet.
5391 19 June 2007: Wouter
5392 - nicer layout in stats.c, review 0.3 change.
5393 - spelling improvement, review 0.3 change.
5394 - uncapped timeout for server selection, so that very fast or slow
5395 servers will stand out from the rest.
5396 - target-fetch-policy: "3 2 1 0 0" config setting.
5397 - fixup queries answered without RD bit (for root prime results).
5398 - refuse AXFR and IXFR requests.
5399 - fixup RD flag in error reply from iterator. fixup RA flag from
5401 - fixup encoding of very short edns buffer sizes, now sets TC bit.
5402 - config options harden-short-bufsize and harden-large-queries.
5404 18 June 2007: Wouter
5405 - same, move subqueries to slumber list when first has resolved.
5406 - fixup last fix for duplicate callbacks.
5407 - another offbyone in targetcounter. Also in Java prototype by the way.
5409 15 June 2007: Wouter
5410 - if a query asks to be notified of the same serviced query result
5411 multiple times, this will succeed. Only one callback will happen;
5412 multiple outbound-list entries result (but the double cleanup of it
5414 - when iterator moves on due to CNAME or referral, it will remove
5415 the subqueries (for other targets). These are put on the slumber
5417 - state module wait subq is OK with no new subqs, an old one may have
5418 stopped, with an error, and it is still waiting for other ones.
5419 - if a query loops, halt entire query (easy way to clean up properly).
5421 14 June 2007: Wouter
5422 - num query targets was > 0 , not >= 0 compared, so that fetch
5423 policy of 0 did nothing.
5425 13 June 2007: Wouter
5426 - debug option: configure --enable-static-exe for compile where
5427 ldns and libevent are linked statically. Default is off.
5428 - make install and make uninstall. Works with static-exe and without.
5429 installation of unbound binary and manual pages.
5430 - alignement problem fix on solaris 64.
5431 - fixup address in case of TCP error.
5433 12 June 2007: Wouter
5434 - num target queries was set to 0 at a bad time. Default it to 0 and
5435 increase as target queries are done.
5436 - synthesize CNAME and DNAME responses from the cache.
5437 - Updated doxygen config for doxygen 1.5.
5438 - aclocal newer version.
5439 - doxygen 1.5 fixes for comments (for the strict check on docs).
5441 11 June 2007: Wouter
5442 - replies on TCP queries have the address field set in replyinfo,
5443 for serviced queries, because the initiator does not know that
5444 a TCP fallback has occured.
5445 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
5446 if qtype directly queries for the type (and then only show that
5447 'unknown type' in the answer section).
5448 - fixed message parsing where rrsigs on their own would be put
5449 in the signature list over the rrsig type.
5452 - fixup error in double linked list insertion for subqueries and
5453 for outbound list of serviced queries for iterator module.
5454 - nicer printout of outgoing port selection.
5455 - fixup cname target readout.
5456 - nicer debug output.
5457 - fixup rrset counts when prepending CNAMEs to the answer.
5458 - fixup rrset TTL for prepended CNAMEs.
5459 - process better check for looping modules, and which submodule to
5461 - subreq insertion code fixup for slumber list.
5462 - VERB_DETAIL, verbosity: 2 level gives short but readable output.
5463 VERB_ALGO, verbosity: 3 gives extensive output.
5464 - fixup RA bit in cached replies.
5465 - fixup CNAME responses from the cache no longer partial response.

5647 - decompress query section, extremely lenient acceptance.
5648 But only for answers from other servers, not for plain queries.
5649 - compression and decompression test cases.
5651 - example.conf interface: line is changed from 127.0.0.1 which leads
5652 to problems if used (restricting communication to the localhost),

5878 This makes all threads service incoming requests, instead of one.
5879 No memory is leaking during reloads, service of queries, etc.
5880 - test that uses ldns-testns -f to test threading. Have to answer
5881 three queries at the same time.
