980 - Change syntax of particular validator error to be easier for
981 machine parse, swap rrset and ip adres info so it looks like:

1026 - Libunbound skips dos-line-endings from etc/hosts.

1028 fails to be writable. This is seconds after startup. You can
1029 load a readonly auto-trust-anchor-file with trust-anchor-file.
1030 The file has to be writable to notice the trust anchor change,
1031 without it, a trust anchor change will be unnoticed and the system
1032 will then become inoperable.
1033 - unbound-control list_insecure command shows the negative trust
1034 anchors currently configured, patch from Jelte Jansen.

1089 - Patch from Brad Smith that syncs compat/getentropy_linux with
1090 OpenBSD's version (2015-03-04).
1091 - 0x20 fallback improved: servfail responses do not count as missing
1092 comparisons (except if all responses are errors),
1093 inability to find nameservers does not fail equality comparisons,
1094 many nameservers does not try to compare more than max-sent-count,
1095 parse failures start 0x20 fallback procedure.
1096 - store caps_response with best response in case downgrade response
1097 happens to be the last one.

1456 - Code cleanup patch from Dag-Erling Smorgrav, with compiler issue
1457 fixes from FreeBSD's copy of Unbound, he notes:
1458 Generate unbound-control-setup.sh at build time so it respects
1459 prefix and sysconfdir from the configure script. Also fix the
1460 umask to match the comment, and the comment to match the umask.
1461 Add const and static where needed. Use unions instead of
1462 playing pointer poker. Move declarations that are needed in
1463 multiple source files into a shared header. Move sldns_bgetc()
1464 from parse.c to buffer.c where it belongs. Introduce a new
1465 header file, worker.h, which declares the callbacks that
1466 all workers must define. Remove those declarations from
1467 libworker.h. Include the correct headers in the correct places.
1468 Fix a few dummy callbacks that don't match their prototype.
1469 Fix some casts. Hide the sbrk madness behind #ifdef HAVE_SBRK.
1470 Remove a useless printf which breaks reproducible builds.
1471 Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
1472 no longer used. Add unbound-control-setup.sh to the list of
1473 generated files. The prototype for libworker_event_done_cb()
1474 needs to be moved from libunbound/libworker.h to
1475 libunbound/worker.h.
1476 - Fixup out-of-directory compile with unbound-control-setup.sh.in.
1480 - unbound-host -D enabled dnssec and reads root trust anchor from

1484 - Feature, unblock-lan-zones: yesno that you can use to make unbound
1485 perform 10.0.0.0/8 and other reverse lookups normally, for use if
1486 unbound is running service for localhost on localhost.
1489 - Updated create_unbound_ad_servers and unbound_cache scripts from
1490 Yuri Voinov in the source/contrib directory. Added
1491 warmup.cmd (and .sh): warm up the DNS cache with your MRU domains.
1494 - Implement draft-ietf-dnsop-rfc6598-rfc6303-01.
1495 - iana portlist updated.
1498 - Contrib windows scripts from Yuri Voinov added to src/contrib:
1499 create_unbound_ad_servers.cmd: enters anti-ad server lists.
1500 unbound_cache.cmd: saves and loads the cache.
1501 - Added unbound-control-setup.cmd from Yuri Voinov to the windows
1502 unbound distribution set. It requires openssl installed in %PATH%.
1505 - Change MAX_SENT_COUNT from 16 to 32 to resolve some cases easier.
1508 - More #567: remove : from output of stub and forward lists, this is

1512 - iana portlist updated.
1513 - Add unbound-control flush_negative that flushed nxdomains, nodata,
1514 and errors from the cache. For dnssec-trigger and NetworkManager,
1515 fixes cases where network changes have localdata that was already
1516 negatively cached from the previous network.
1518 23 April 2014: Wouter
1519 - Patch from Jeremie Courreges-Anglas to use arc4random_uniform
1520 if available on the OS, it gets entropy from the OS.
1522 15 April 2014: Wouter
1523 - Fix compile with libevent2 on FreeBSD.
1525 11 April 2014: Wouter
1526 - Fix #502: explain that do-ip6 disable does not stop AAAA lookups,
1527 but it stops the use of the ipv6 transport layer for DNS traffic.
1528 - iana portlist updated.
1530 10 April 2014: Wouter
1531 - iana portlist updated.
1532 - Patch from Hannes Frederic Sowa for Linux 3.15 fragmentation
1533 option for DNS fragmentation defense.

1538 +i annotation in output of list_forwards, also for list_stubs
1539 (for NetworkManager integration.)
1540 - Fix #554: use unsigned long to print 64bit statistics counters on
1542 - Fix #558: failed prefetch lookup does not remove cached response
1543 but delays next prefetch (in lieu of caching a SERVFAIL).
1544 - Fix #545: improved logging, the ip address of the error is printed
1545 on the same log-line as the error.
1547 8 April 2014: Wouter
1548 - Fix #574: make test fails on Ubuntu 14.04. Disabled remote-control
1549 in testbound scripts.
1550 - iana portlist updated.
1552 7 April 2014: Wouter
1553 - C.ROOT-SERVERS.NET has an IPv6 address, and we updated the root
1554 hints (patch from Anand Buddhdev).
1555 - Fix #572: Fix unit test failure for systems with different
1558 28 March 2014: Wouter
1559 - Fix #569: do_tcp is do-tcp in unbound.conf man page.
1561 25 March 2014: Wouter
1562 - Patch from Stuart Henderson to build unbound-host man from .1.in.
1564 24 March 2014: Wouter

1578 21 February 2014: Wouter
1579 - iana portlist updated.
1581 20 February 2014: Matthijs
1582 - Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is
1583 received. This is okay according 4035, but not after revising
1584 existence in 4592. NSEC empty non-terminals exist and thus the
1585 RCODE should have been NOERROR. If this occurs, and the RRsets
1586 are secure, we set the RCODE to NOERROR and the security status
1587 of the response is also considered secure.
1589 14 February 2014: Wouter
1590 - Works on Minix (3.2.1).
1592 11 February 2014: Wouter

1617 - Fix for hex to string in unknown, atma and nsap.
1618 - fixup nss compile (no ldns in it).
1619 - fixup warning in unitldns
1620 - fixup WKS and rdata type service to print unsigned because strings
1621 are not portable; they cannot be read (for sure) on other computers.
1622 - fixup type EUI48 and EUI64, type APL and type IPSECKEY in string
1625 30 January 2014: Wouter
1626 - delay-close does not act if there are udp-wait queries, so that
1627 it does not make a socketdrain DoS easier.
1629 28 January 2014: Wouter
1630 - iana portlist updated.
1631 - iana portlist test updated so it does not touch the source
1632 if there are no changes.
1633 - delay-close: msec option that delays closing ports for which
1634 the UDP reply has timed out. Keeps the port open, only accepts
1635 the correct reply. This correct reply is not used, but the port
1636 is open so that no port-denied ICMPs are generated.
1638 27 January 2014: Wouter
1639 - reuseport is attempted, then fallback to without on failure.
1641 24 January 2014: Wouter
1642 - Change unbound-event.h to use void* buffer, length idiom.
1643 - iana portlist updated.
1644 - unbound-event.h is installed if you configure --enable-event-api.
1645 - speed up unbound (reports say it could be up to 10%), by reducing
1646 lock contention on localzones.lock. It is changed to an rwlock.
1647 - so-reuseport: yesno option to distribute queries evenly over
1648 threads on Linux (Thanks Robert Edmonds).
1651 21 January 2014: Wouter
1652 - Fix #547: no trustanchor written if filesystem full, fclose checked.
1654 17 January 2014: Wouter
1655 - Fix isprint() portability in sldns, uses unsigned int.
1656 - iana portlist updated.
1658 16 January 2014: Wouter
1659 - fix #544: Fixed +i causes segfault when running with module conf
1661 - Windows port, adjust %lld to %I64d, and warning in win_event.c.
1663 14 January 2014: Wouter
1664 - iana portlist updated.
1667 - Fix bug in cachedump that uses sldns.
1668 - update pythonmod for ldns_ to sldns_ name change.
1671 - Fix sldns to use sldns_ prefix for all ldns_ variables.
1672 - Fix windows compile to compile with sldns.
1675 - Fix sldns to make globals use sldns_ prefix. This fixes
1676 linking with libldns that uses global variables ldns_ .
1679 - Fix bug#537: compile python plugin without ldns library.
1682 - Fix bug#536: acl_deny_non_local and refuse_non_local added.
1685 - Patch from Neel Goyal to fix async id assignment if callback
1686 is called by libunbound in the mesh attach.
1687 - Accept ip-address: as an alternative for interface: for
1688 consistency with nsd.conf syntax.
1691 - Patch from Neel Goyal to fix callback in libunbound.
1694 - if configured --with-libunbound-only fix make install.
1697 - Fix #531: Set SO_REUSEADDR so that the wildcard interface and a
1698 more specific interface port 53 can be used at the same time, and
1699 one of the daemons is unbound.
1700 - iana portlist update.
1701 - separate ldns into core ldns inside ldns/ subdirectory. No more
1702 --with-ldns is needed and unbound does not rely on libldns.
1703 - portability fixes for new USE_SLDNS ldns subdir codebase.
1706 - Patch from Neel Goyal: Add an API call to set an event base on an
1707 existing ub_ctx. This basically just destroys the current worker and
1708 sets the event base to the current. And fix a deadlock in
1709 ub_resolve_event – the cfglock is held when libworker_create is
1710 called. This ends up trying to acquire the lock again in
1711 context_obtain_alloc in the call chain.
1712 - Fix #528: if very high logging (4 or more) segfault on allow_snoop.
1715 - unbound-event.h is installed if configured --with-libevent. It
1716 contains low-level library calls, that use libevent's event_base
1717 and an ldns_buffer for the wire return packet to perform async
1718 resolution in the client's eventloop.
1721 - 1.4.21 tag created.
1722 - trunk has 1.4.22 number inside it.
1723 - iana portlist updated.
1724 - acx_nlnetlabs.m4 to 26; improve FLTO help text.
1727 - Fix#524: max-udp-size not effective to non-EDNS0 queries, from
1731 - MIN_TTL and MAX_TTL also in time_t.
1732 - tag 1.4.21rc1 made again.
1735 - More fixes for bug#519: for the threaded case test if the bg
1736 thread has been killed, on ub_ctx_delete, to avoid hangs.
1739 - more fixes that I overlooked.
1740 - review fixes from Willem.
1743 - Fix#520: Errors found by static analysis from Tomas Hozza(redhat).
1746 - Fix for 2038, with time_t instead of uint32_t.
1749 - Fix#519 ub_ctx_delete may hang in some scenarios (libunbound).
1752 - Fix uninit variable in fix#516.
1755 - Fix#516 dnssec lameness detection for answers that are improper.
1761 - Fix#512 memleak in testcode for testbound (if it fails).
1762 - Fix#512 NSS returned arrays out of setup function to be statics.
1765 - max include of 100.000 files (depth and globbed at one time).
1766 This is to preserve system memory in bug cases, or endless cases.
1767 - iana portlist updated.
1770 - streamtcp man page, contributed by Tomas Hozza.
1771 - iana portlist updated.
1772 - libunbound documentation on how to avoid openssl race conditions.

1776 not connected, to avoid spamming syslog.
1777 - configure --disable-flto option (from Robert Edmonds).
1780 - Fix for const string literals in C++ for libunbound, from Karel
1782 - iana portlist updated.
1785 - Fixup manpage syntax.
1788 - get_option and set_option support for log-time-ascii, python-script
1789 val-sig-skew-min and val-sig-skew-max. log-time-ascii takes effect
1790 immediately. The others are mostly useful for libunbound users.

2384 - fixup windows compile with ssl support.
2385 - Fix double free in unbound-host, reported by Steve Grubb.
2386 - iana portlist updated.
2388 1 November 2011: Wouter
2389 - dns over ssl support as a client, ssl-upstream yes turns it on.
2390 It performs an SSL transaction for every DNS query (250 msec).
2391 - documentation for new options: ssl-upstream, ssl-service-key and
2393 - iana portlist updated.
2394 - fix -flto detection on Lion for llvm-gcc.
2396 31 October 2011: Wouter
2397 - dns over ssl support, ssl-service-pem and ssl-service-key files
2398 can be given and then TCP queries are serviced wrapped in SSL.
2400 27 October 2011: Wouter
2401 - lame-ttl and lame-size options no longer exist, it is integrated
2402 with the host info. They are ignored (with verbose warning) if
2403 encountered to keep the config file backwards compatible.
2404 - fix iana-update for changing gzip compression of results.
2405 - fix export-all-symbols on OSX.
2407 26 October 2011: Wouter

2410 This fixes bug #416.
2411 - fix iana_update target for gzipped file on iana site.
2413 24 October 2011: Wouter
2414 - Fix resolve of partners.extranet.microsoft.com with a fix for the
2415 server selection for choosing out of a (particular) list of bad
2417 - Fix make_new_space function so that the incoming query is not
2418 overwritten if a jostled out query causes a waiting query to be
2419 resumed that then fails and sends an error message. (Thanks to
2422 21 October 2011: Wouter
2423 - fix --enable-allsymbols, fptr wlist is disabled on windows with this
2424 option enabled because of memory layout exe vs dll.
2426 19 October 2011: Wouter
2427 - fix unbound-anchor for broken strptime on OSX lion, detected
2429 - Detect if GOST really works, openssl1.0 on OSX fails.
2430 - Implement ipv6%interface notation for scope_id usage.
2432 17 October 2011: Wouter
2433 - better documentation for inform_super (Thanks Yang Zhe).
2435 14 October 2011: Wouter
2436 - Fix for out-of-memory condition in libunbound (thanks
2439 13 October 2011: Wouter
2440 - Fix --enable-allsymbols, it depended on link specifics of the
2441 target platform, or fptr_wlist assertion failures could occur.
2443 12 October 2011: Wouter
2444 - updated contrib/unbound_munin_ to family=auto so that it works with
2445 munin-node-configure automatically (if installed as
2446 /usr/local/share/munin/plugins/unbound_munin_ ).
2448 27 September 2011: Wouter
2449 - unbound.exe -w windows option for start and stop service.
2451 23 September 2011: Wouter
2452 - TCP-upstream calculates tcp-ping so server selection works if there
2455 20 September 2011: Wouter
2456 - Fix classification of NS set in answer section, where there is a
2457 parent-child server, and the answer has the AA flag for dir.slb.com.
2458 Thanks to Amanda Constant from Secure64.
2460 16 September 2011: Wouter
2461 - fix bug #408: accept patch from Steve Snyder that comments out
2462 unused functions in lookup3.c.
2463 - iana portlist updated.
2464 - fix EDNS1480 change memleak and TCP fallback.
2465 - fix various compiler warnings (reported by Paul Wouters).
2466 - max sent count. EDNS1480 only for rtt < 5000. No promiscuous
2467 fetch if sentcount > 3, stop query if sentcount > 16. Count is
2468 reset when referral or CNAME happens. This makes unbound better
2469 at managing large NS sets, they are explored when there is continued
2470 interest (in the form of queries).
2472 15 September 2011: Wouter
2474 - trunk contains 1.4.14 in development.
2475 - Unbound probes at EDNS1480 if there an EDNS0 timeout.
2477 12 September 2011: Wouter
2478 - Reverted dns EDNS backoff fix, it did not help and needs
2479 fragmentation fixes instead.
2482 7 September 2011: Wouter
2483 - Fix operation in ipv6 only (do-ip4: no) mode.
2485 6 September 2011: Wouter
2486 - fedora specfile updated.
2488 5 September 2011: Wouter
2491 2 September 2011: Wouter
2492 - iana portlist updated.
2494 26 August 2011: Wouter
2495 - Fix num-threads 0 does not segfault, reported by Simon Deziel.
2496 - Fix validation failures due to EDNS backoff retries, the retry
2497 for fetch of data has want_dnssec because the iter_indicate_dnssec
2498 function returns true when validation failure retry happens, and
2499 then the serviced query code does not fallback to noEDNS, even if
2500 the cache says it has this. This helps for DLV deployment when
2501 the DNSSEC status is not known for sure before the lookup concludes.
2503 24 August 2011: Wouter
2504 - Applied patch from Karel Slany that fixes a memory leak in the
2505 unbound python module, in string conversions.
2507 22 August 2011: Wouter
2508 - Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
2509 Zhang and Luo Ce). Unbound responds with the RR types that are
2510 available at the name for qtype ANY and validates those RR types.
2511 It does not test for completeness (i.e. with NSEC or NSEC3 query),
2512 and it does not follow the CNAME or DNAME to another name (with
2513 even more data for the already large response).
2514 - Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
2515 - Documented the options that work with control set_option command.
2516 - tcp-upstream yes/no option (works with set_option) for tunnels.
2518 18 August 2011: Wouter
2519 - fix autoconf call in makedist crosscompile to RC or snapshot.
2521 17 August 2011: Wouter

2524 - iana portlist updated.
2526 10 August 2011: Wouter
2527 - Fix python site-packages path to /usr/lib64.
2528 - updated patch from Tom.
2529 - fix memory and fd leak after out-of-memory condition.
2531 9 August 2011: Wouter
2532 - patch from Tom Hendrikx fixes load of python modules.
2534 8 August 2011: Wouter

2538 - Fix autoconf 2.68 warnings
2540 14 July 2011: Wouter
2541 - Unbound implements RFC6303 (since version 1.4.7).
2542 - tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
2543 meantime, those are for 1.4.13).
2544 - iana portlist updated.
2546 13 July 2011: Wouter
2547 - Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
2549 11 July 2011: Wouter
2550 - Fix wildcard expansion no-data reply under an optout NSEC3 zone is
2551 validated as insecure, reported by Jia Li (lijia@cnnic.cn).
2554 - 1.4.12rc1 tag created.
2557 - version number in example config file.
2558 - fix that --enable-static-exe does not complain about it unknown.
2560 30 June 2011: Wouter
2561 - tag relase 1.4.11, trunk is 1.4.12 development.
2562 - iana portlist updated.
2563 - fix bug#395: id bits of other query may leak out under conditions
2564 - fix replyaddr count wrong after jostled queries, which leads to
2565 eventual starvation where the daemon has no replyaddrs left to use.
2566 - fix comment about rndc port, that referred to the old port number.
2567 - fix that the listening socket is not closed when too many remote
2568 control connections are made at the same time.
2569 - removed ldns-src tarball inside the unbound tarball.
2571 23 June 2011: Wouter
2572 - Changed -flto check to support clang compiler.
2573 - tag 1.4.11rc3 created.
2575 17 June 2011: Wouter
2576 - tag 1.4.11rc1 created.

2578 - updated aclocal.m4 and libtool to match.
2579 - tag 1.4.11rc2 created.
2581 16 June 2011: Wouter
2582 - log-queries: yesno option, default is no, prints querylog.
2583 - version is 1.4.11.
2585 14 June 2011: Wouter
2586 - Use -flto compiler flag for link time optimization, if supported.
2587 - iana portlist updated.
2589 12 June 2011: Wouter
2590 - IPv6 service address for d.root-servers.net (2001:500:2D::D).
2592 10 June 2011: Wouter
2593 - unbound-control has version number in the header,
2594 UBCT[version]_space_ is the header sent by the client now.
2595 - Unbound control port number is registered with IANA:
2596 ub-dns-control 8953/tcp unbound dns nameserver control
2597 This is the new default for the control-port config setting.
2598 - statistics-interval prints the number of jostled queries to log.
2601 - Fix Makefile for U in environment, since wrong U is more common than
2602 deansification necessity.
2603 - iana portlist updated.
2604 - updated ldns tarball to 1.6.10rc2 snapshot of today.
2607 - Fix assertion failure when unbound generates an empty error reply
2608 in response to a query, CVE-2011-1922 VU#531342.
2609 - This fix is in tag 1.4.10.
2610 - defense in depth against the above bug, an error is printed to log
2611 instead of an assertion failure.
2614 - bug#386: --enable-allsymbols option links all binaries to libunbound
2615 and reduces install size significantly.
2616 - feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
2617 - iana portlist updated.
2618 - Fix TTL of SOA so negative TTL is separately cached from normal TTL.
2620 14 April 2011: Wouter
2621 - configure created with newer autoconf 2.66.
2623 12 April 2011: Wouter
2624 - bug#378: Fix that configure checks for ldns_get_random presence.
2626 8 April 2011: Wouter
2627 - iana portlist updated.
2628 - queries with CD flag set cause DNSSEC validation, but the answer is
2629 not withheld if it is bogus. Thus, unbound will retry if it is bad
2630 and curb the TTL if it is bad, thus protecting the cache for use by
2631 downstream validators.
2632 - val-override-date: -1 ignores dates entirely, for NTP usage.
2634 29 March 2011: Wouter
2635 - harden-below-nxdomain: changed so that it activates when the
2636 cached nxdomain is dnssec secure. This avoids backwards
2637 incompatibility because those old servers do not have dnssec.
2639 24 March 2011: Wouter
2640 - iana portlist updated.
2644 17 March 2011: Wouter
2645 - bug#370: new unbound.spec for CentOS 5.x from Harold Jones.
2646 Applied but did not do the --disable-gost.
2648 10 March 2011: Wouter
2649 - tag 1.4.9 release candidate 1 created.
2651 3 March 2011: Wouter
2652 - updated ldns to today.
2654 1 March 2011: Wouter
2655 - Fix no ADflag for NXDOMAIN in NSEC3 optout. And wildcard in optout.
2656 - give config parse error for multiple names on a stub or forward zone.
2657 - updated ldns tarball to 1.6.9(todays snapshot).
2659 24 February 2011: Wouter
2660 - bug #361: Fix, time.elapsed variable not reset with stats_noreset.
2662 23 February 2011: Wouter
2663 - iana portlist updated.
2664 - common.sh to version 3.
2666 18 February 2011: Wouter
2667 - common.sh in testdata updated to version 2.
2669 15 February 2011: Wouter
2670 - Added explicit note on unbound-anchor usage:
2671 Please note usage of unbound-anchor root anchor is at your own risk
2672 and under the terms of our LICENSE (see that file in the source).
2674 11 February 2011: Wouter
2675 - iana portlist updated.
2676 - tpkg updated with common.sh for common functionality.
2678 7 February 2011: Wouter
2679 - Added regression test for addition of a .net DS to the root, and
2680 cache effects with different TTL for glue and DNSKEY.
2681 - iana portlist updated.

2684 - Fix remove private address does not throw away entire response.
2686 24 January 2011: Wouter
2689 19 January 2011: Wouter
2690 - fix bug#349: no -L/usr for ldns.
2692 18 January 2011: Wouter
2693 - ldns 1.6.8 tarball included.
2696 17 January 2011: Wouter
2697 - add get and set option for harden-below-nxdomain feature.
2698 - iana portlist updated.
2700 14 January 2011: Wouter
2701 - Fix so a changed NS RRset does not get moved name stuck on old
2702 server, for type NS the TTL is not increased.
2704 13 January 2011: Wouter
2705 - Fix prefetch so it does not get stuck on old server for moved names.
2707 12 January 2011: Wouter
2708 - iana portlist updated.
2710 11 January 2011: Wouter
2711 - Fix insecure CNAME sequence marked as secure, reported by Bert

2718 - bug#346: remove ITAR scripts from contrib, the service is discontinued, use the root.
2719 - iana portlist updated.
2721 23 December 2010: Wouter
2722 - Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
2724 21 December 2010: Wouter
2725 - algorithm compromise protection using the algorithms signalled in
2726 the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
2727 and thus, if you have multiple algorithms in your trust-anchor-file
2728 then it will now behave different than before. Also, 5011 rollover
2729 for algorithms needs to be double-signature until the old algorithm
2731 It is not an option, because I see no use to turn the security off.
2732 - iana portlist updated.
2734 17 December 2010: Wouter
2735 - squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
2736 - fix validation in this case: CNAME to nodata for co-hosted opt-in
2737 NSEC3 insecure delegation, was bogus, fixed to be insecure.
2739 16 December 2010: Wouter

2754 - iana portlist updated.
2756 18 November 2010: Wouter
2757 - harden-below-nxdomain option, default off (because very old
2758 software may be incompatible). We could enable it by default in
2761 17 November 2010: Wouter
2762 - implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
2763 - make test output nicer.
2765 15 November 2010: Wouter
2766 - silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
2767 - iana portlist updated.
2768 - so-sndbuf option for very busy servers, a bit like so-rcvbuf.
2770 9 November 2010: Wouter
2771 - unbound-anchor compiles with openssl 0.9.7.
2773 8 November 2010: Wouter
2774 - release tag 1.4.7.

2785 - Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
2787 2 November 2010: Wouter
2791 1 November 2010: Wouter
2792 - GOST code enabled by default (RFC 5933).
2794 27 October 2010: Wouter
2795 - Fix uninit value in dump_infra print.
2796 - Fix validation failure for parent and child on same server with an
2797 insecure childzone and a CNAME from parent to child.
2798 - Configure detects libev-4.00.
2800 26 October 2010: Wouter
2801 - dump_infra and flush_infra commands for unbound-control.
2802 - no timeout backoff if meanwhile a query succeeded.
2803 - Change of timeout code. No more lost and backoff in blockage.
2804 At 12sec timeout (and at least 2x lost before) one probe per IP
2805 is allowed only. At 120sec, the IP is blocked. After 15min, a
2806 120sec entry has a single retry packet.
2808 25 October 2010: Wouter
2809 - Configure errors if ldns is not found.
2811 22 October 2010: Wouter
2812 - Windows 7 fix for the installer.
2814 21 October 2010: Wouter
2815 - Fix bug where fallback_tcp causes wrong roundtrip and edns
2816 observation to be noted in cache. Fix bug where EDNSprobe halted
2817 exponential backoff if EDNS status unknown.
2818 - new unresponsive host method, exponentially increasing block backoff.
2819 - iana portlist updated.
2821 20 October 2010: Wouter
2822 - interface automatic works for some people with ip6 disabled.
2823 Therefore the error check is removed, so they can use the option.
2825 19 October 2010: Wouter
2826 - Fix for request list growth, if a server has long timeout but the
2827 lost counter is low, then its effective rtt is the one without
2828 exponential backoff applied. Because the backoff is not working.
2829 The lost counter can then increase and the server is blacklisted,
2830 or the lost counter does not increase and the server is working
2833 18 October 2010: Wouter
2834 - iana portlist updated.
2836 13 October 2010: Wouter
2837 - Fix TCP so it uses a random outgoing-interface.
2838 - unbound-anchor handles ADDPEND keystate.
2840 11 October 2010: Wouter
2841 - Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
2842 the zone has a secure delegation hosted on the same server did not
2843 verify as secure (it was insecure by mistake).
2844 - iana portlist updated.
2845 - ldns tarball updated (for reading cachedumps with bad RR data).
2847 1 October 2010: Wouter

2849 - Fix alloc_reg_release for longer uptime in out of memory conditions.
2851 28 September 2010: Wouter

2856 - iana portlist updated.
2858 24 September 2010: Wouter

2861 23 September 2010: Wouter
2862 - unbound-anchor app, unbound requires libexpat (xml parser library).
2864 22 September 2010: Wouter
2865 - compliance with draft-ietf-dnsop-default-local-zones-14, removed
2866 reverse ipv6 orchid prefix from builtin list.
2867 - iana portlist updated.
2869 17 September 2010: Wouter
2870 - DLV has downgrade protection again, because the RFC says so.
2871 - iana portlist updated.
2873 16 September 2010: Wouter
2874 - Algorithm rollover operational reality intrudes, for trust-anchor,
2875 5011-store, and DLV-anchor if one key matches it's good enough.
2876 - iana portlist updated.
2877 - Fix reported validation error in out of memory condition.
2879 15 September 2010: Wouter

2887 13 September 2010: Wouter
2888 - bug#327: Fix for cannot access stub zones until the root is primed.
2890 9 September 2010: Wouter
2891 - unresponsive servers are not completely blacklisted (because of
2892 firewalls), but also not probed all the time (because of the request
2893 list size it generates). The probe rate is 1%.
2894 - iana portlist updated.
2896 20 August 2010: Wouter
2897 - openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
2898 iterator get_mem includes priv_get_mem. delegpt nodup removed.
2899 listen_pushback, query_info_allocqname, write_socket, send_packet,
2900 comm_point_set_cb_arg and listen_resume removed.
2902 19 August 2010: Wouter
2903 - Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
2904 Delegpt structures checked for duplicates always.
2905 No more nameserver lookups generated when depth is full anyway.
2906 - example.conf notes how to do DNSSEC validation and track the root.
2907 - iana portlist updated.
2909 18 August 2010: Wouter
2910 - Fix bug#322: configure does not respect CFLAGS on Solaris.
2911 Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
2912 if use sun-cc, but some systems need different flags.
2914 16 August 2010: Wouter
2915 - Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
2916 changes, uses m4_bpatsubst now.
2917 - make test (or make check) should be more portable and run the unit
2918 test and testbound scripts. (make longtest has special requirements).
2920 13 August 2010: Wouter
2921 - More pleasant remote control command parsing.
2922 - documentation added for return values reported by doxygen 1.7.1.
2923 - iana portlist updated.
2925 9 August 2010: Wouter
2926 - Fix name of rrset printed that failed validation.
2928 5 August 2010: Wouter
2929 - Return NXDOMAIN after chain of CNAMEs ends at name-not-found.
2931 4 August 2010: Wouter
2932 - Fix validation in case a trust anchor enters into a zone with
2933 unsupported algorithms.
2935 3 August 2010: Wouter
2936 - updated ldns tarball with bugfixes.
2937 - release tag 1.4.6.
2938 - trunk becomes 1.4.7 develop.
2939 - iana portlist updated.
2941 22 July 2010: Wouter
2942 - more error details on failed remote control connection.
2944 15 July 2010: Wouter
2945 - rlimit adjustments for select and ulimit can happen at the same time.
2947 14 July 2010: Wouter
2948 - Donation text added to README.
2949 - Fix integer underflow in prefetch ttl creation from cache. This
2950 fixes a potential negative prefetch ttl.
2952 12 July 2010: Wouter
2953 - Changed the defaults for num-queries-per-thread/outgoing-range.
2954 For builtin-select: 512/960, for libevent 1024/4096 and for
2955 windows 24/48 (because of win api). This makes the ratio this way
2956 to improve resilience under heavy load. For high performance, use
2957 libevent and possibly higher numbers.
2959 10 July 2010: Wouter
2960 - GOST enabled if SSL is recent and ldns has GOST enabled too.
2961 - ldns tarball updated.
2964 - iana portlist updated.
2965 - Fix validation of qtype DNSKEY when a key-cache entry exists but
2966 no rr-cache entry is used (it expired or prefetch), it then goes
2967 back up to the DS or trust-anchor to validate the DNSKEY.
2970 - Neat function prototypes, unshadowed local declarations.
2973 - failure to chown the pidfile is not fatal any more.
2974 - testbound uses UTC timezone.
2975 - ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
2976 /usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
2979 - log if a server is skipped because it is on the donotquery list,
2980 at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
2981 - added feature to print configure date, target and options with -h.
2982 - added feature to print event backend system details with -h.
2983 - wdiff is not actually required by make test, updated requirements.
2986 - Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
2987 must be signed with all algorithms from the DS rrset at the parent.
2988 This is now checked and becomes bogus if not.
2990 28 June 2010: Wouter
2991 - Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
2992 in overload situations to be about 5 qps for the class of shortly
2994 The capacity of the resolver is then about (numqueriesperthread / 2)
2995 / (average time for such long queries) qps for long queries.
2996 And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
2997 qps for short queries, per thread.
2998 - Fix the max number of reply-address count to be applied for duplicate
2999 queries, and not for new query list entries. This raises the memory
3000 usage to a max of (16+1)*numqueriesperthread reply addresses.
3002 25 June 2010: Wouter
3003 - Fix handling of corner case reply from lame server, follows rfc2308.
3004 It could lead to a nodata reply getting into the cache if the search
3005 for a non-lame server turned up other misconfigured servers.
3006 - unbound.h has extern "C" statement for easier include in c++.
3008 23 June 2010: Wouter
3009 - iana portlist updated.
3010 - makedist upgraded cross compile openssl option, like this:
3011 ./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
3013 22 June 2010: Wouter
3014 - Unbound reports libev or libevent correctly in logs in verbose mode.
3015 - Fix to unload gost dynamic library module for leak testing.
3017 18 June 2010: Wouter
3018 - iana portlist updated.
3020 17 June 2010: Wouter
3021 - Add AAAA to root hints for I.ROOT-SERVERS.NET.
3023 16 June 2010: Wouter
3024 - Fix assertion failure reported by Kai Storbeck from XS4ALL, the
3025 assertion was wrong.
3026 - updated ldns tarball.
3028 15 June 2010: Wouter
3029 - tag 1.4.5 created.
3030 - trunk contains 1.4.6 in development.
3031 - Fix TCPreply on systems with no writev, if just 1 byte could be sent.
3032 - Fix to use one pointer less for iterator query state store_parent_NS.
3033 - makedist crosscompile to windows uses builtin ldns not host ldns.
3034 - Max referral count from 30 to 130, because 128 one character domains
3036 - added documentation for the histogram printout to syslog.
3038 11 June 2010: Wouter
3039 - When retry to parent the retrycount is not wiped, so failed
3040 nameservers are not tried again.
3041 - iana portlist updated.
3043 10 June 2010: Wouter
3044 - Fix bug where a long loop could be entered, now cycle detection
3045 has a loop-counter and maximum search amount.
3048 - iana portlist updated.
3049 - 1.4.5rc1 tag created.
3052 - ldns tarball updated, 1.6.5.
3053 - review comments, split dependency cycle tracking for parentside
3054 last resort lookups for A and AAAA so there are more lookup options.
3057 - Fix compile warning if compiled without threads.
3058 - updated ldns-tarball with current ldns svn (pre 1.6.5).
3059 - GOST disabled-by-default, the algorithm number is allocated but the
3060 RFC is still has to pass AUTH48 at the IETF.
3063 - Ignore Z flag in incoming messages too.
3064 - Fix storage of negative parent glue if that last resort fails.
3065 - libtoolize 2.2.6b, autoconf 2.65 applied to configure.
3066 - new splint flags for newer splint install.
3069 - Fix AD flag handling, it could in some cases mistakenly copy the AD
3070 flag from upstream servers.
3071 - alloc_special_obtain out of memory is not a fatal error any more,
3072 enabling unbound to continue longer in out of memory conditions.
3073 - parentside names are dispreferred but not said to be dnssec-lame.
3074 - parentside check for cached newname glue.
3075 - fix parentside and querytargets modulestate, for dump_requestlist.
3076 - unbound-control-setup makes keys -rw-r--- so not all users permitted.
3077 - fix parentside from cache to be marked dispreferred for bad names.
3080 - iana portlist updated.
3081 - parent-child disagreement approach altered. Older fixes are
3082 removed in place of a more exhaustive search for misconfigured data
3083 available via the parent of a delegation.
3084 This is designed to be throttled by cache entries, with TTL from the
3085 parent if possible. Additionally the loop-counter is used.
3086 It also tests for NS RRset differences between parent and child.
3087 The fetch of misconfigured data should be more reliable and thorough.
3088 It should work reliably even with no or only partial data in cache.
3089 Data received from the child (as always) is deemed more
3090 authoritative than information received from the delegation parent.
3091 The search for misconfigured data is not performed normally.
3094 - Contribution from Migiel de Vos (Surfnet): nagios patch for
3095 unbound-host, in contrib/ (in the source tarball). Makes
3096 unbound-host suitable for monitoring dnssec(-chain) status.
3099 - EDNS timeout code will not fire if EDNS status already known.
3100 - EDNS failure not stored if EDNS status known to work.
3103 - Fix resolution for domains like safesvc.com.cn. If the iterator
3104 can not recurse further and it finds the delegation in a state
3105 where it would otherwise have rejected it outhand if so received
3106 from a cache lookup, then it can try to ask higherup (with loop
3108 - Fix comments in iter_utils:dp_is_useless.
3111 - Fix various compiler warnings from the clang llvm compiler.
3112 - iana portlist updated.
3115 - Fix bug#308: spelling error in variable name in parser and lexer.
3118 - Fix dnssec-missing detection that was turned off by server selection.
3119 - Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
3120 reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
3121 113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
3123 29 April 2010: Wouter
3124 - Fix for dnssec lameness detection to use the key cache.
3125 - infra cache entries that are expired are wiped clean. Previously
3126 it was possible to not expire host data (if accessed often).
3128 28 April 2010: Wouter
3129 - ldns tarball updated and GOST support is detected and then enabled.
3130 - iana portlist updated.
3131 - Fix detection of gost support in ldns (reported by Chris Smith).
3133 27 April 2010: Wouter
3134 - unbound-control get_option domain-insecure shows config file items.
3135 - fix retry sequence if prime hints are recursion-lame.
3136 - autotrust anchor file can be initialized with a ZSK key as well.
3137 - harden-referral-path does not result in failures due to max-depth.
3138 You can increase the max-depth by adding numbers (' 0') after the
3139 target-fetch-policy, this increases the depth to which is checked.
3141 26 April 2010: Wouter
3142 - Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
3143 CPPFLAGS during configure process.
3144 - if libev is installed on the base system (not libevent), detect
3145 it from the event.h header file and link with -lev.
3146 - configlexer.lex gets config.h, and configyyrename.h added by make,
3147 no more double include.
3148 - More strict scrubber (Thanks to George Barwood for the idea):
3149 NS set must be pertinent to the query (qname subdomain nsname).
3150 - Fix bug#307: In 0x20 backoff fix fallback so the number of
3151 outstanding queries does not become -1 and block the request.
3152 Fixed handling of recursion-lame in combination with 0x20 fallback.
3153 Fix so RRsets are compared canonicalized and sorted if the immediate
3154 comparison fails, this makes it work around round-robin sites.
3156 23 April 2010: Wouter
3157 - Squelch log message: sendto failed permission denied for
3158 255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
3159 - Fix to fetch data as last resort more tenaciously. When cycle
3160 targets cause the server selection to believe there are more options
3161 when they really are not there, the server selection is reinitiated.
3162 - Fix fetch from blacklisted dnssec lame servers as last resort. The
3163 server's IP address is then given in validator errors as well.
3164 - Fix local-zone type redirect that did not use the query name for
3167 22 April 2010: Wouter
3169 - trunk contains 1.4.5 in development.
3170 - Fix validation failure for qtype ANY caused by a RRSIG parse failure.
3171 The validator error message was 'no signatures from ...'.
3173 16 April 2010: Wouter
3174 - more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
3177 15 April 2010: Wouter
3178 - ECC-GOST algorithm number 12 that is assigned by IANA. New test
3179 example key and signatures for GOST. GOST requires openssl-1.0.0.
3180 GOST is still disabled by default.
3182 9 April 2010: Wouter
3183 - Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
3184 get into an endless loop, if 0x20 was enabled, and buffers are small
3185 or particular broken packets are received.
3186 - Fix chain of trust with CNAME at an intermediate step, for the DS
3189 8 April 2010: Wouter
3190 - Fix validation of queries with wildcard names (*.example).
3192 6 April 2010: Wouter
3193 - Fix EDNS probe for .de DNSSEC testbed failure, where the infra
3194 cache timeout coincided with a server update, the current EDNS
3195 backoff is less sensitive, and does not cache the backoff unless
3196 the backoff actually works and the domain is not expecting DNSSEC.
3197 - GOST support with correct algorithm numbers.
3199 1 April 2010: Wouter
3200 - iana portlist updated.
3202 24 March 2010: Wouter
3203 - unbound control flushed items are not counted when flushed again.
3205 23 March 2010: Wouter
3206 - iana portlist updated.
3208 22 March 2010: Wouter
3209 - unbound-host disables use-syslog from config file so that the
3210 config file for the main server can be used more easily.
3211 - fix bug#301: unbound-checkconf could not parse interface
3212 '0.0.0.0@5353', even though unbound itself worked fine.
3214 19 March 2010: Wouter
3215 - fix fwd_ancil test to pass if the socket options are not supported.
3217 18 March 2010: Wouter
3218 - Fixed random numbers for port, interface and server selection.
3219 Removed very small bias.
3220 - Refer to the listing in unbound-control man page in the extended
3221 statistics entry in the unbound.conf man page.
3223 16 March 2010: Wouter
3224 - Fix interface-automatic for OpenBSD: msg.controllen was too small,
3225 also assertions on ancillary data buffer.
3226 - check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
3227 - for NSEC3 check if signatures are cached.
3229 15 March 2010: Wouter
3230 - unit test for util/regional.c.
3232 12 March 2010: Wouter
3233 - Reordered configure checks so fork and -lnsl -lsocket checks are
3234 earlier, and thus later checks benefit from and do not hinder them.
3235 - iana portlist updated.
3236 - ldns tarball updated.
3237 - Fix python use when multithreaded.
3238 - Fix solaris python compile.
3239 - Include less in config.h and include per code file for ldns, ssl.
3241 11 March 2010: Wouter
3242 - another memory allocation option: --enable-alloc-nonregional.
3243 exposes the regional allocations to other memory purifiers.
3244 - fix for memory alignment in struct sock_list allocation.
3245 - Fix for MacPorts ldns without ssl default, unbound checks if ldns
3246 has dnssec functionality and uses the builtin if not.
3247 - Fix daemonize on Solaris 10, it did not detach from terminal.
3248 - tag 1.4.3 created.
3249 - trunk is 1.4.4 in development.
3250 - spelling fix in validation error involving cnames.
3252 10 March 2010: Wouter
3253 - --enable-alloc-lite works with test set.
3254 - portability in the testset: printf format conversions, prototypes.
3256 9 March 2010: Wouter
3257 - tag 1.4.2 created.
3258 - trunk is 1.4.3 in development.
3259 - --enable-alloc-lite debug option.
3261 8 March 2010: Wouter
3262 - iana portlist updated.
3264 4 March 2010: Wouter
3265 - Fix crash in control channel code.
3267 3 March 2010: Wouter
3268 - better casts in pipe code, brackets placed wrongly.
3269 - iana portlist updated.
3271 1 March 2010: Wouter
3272 - make install depends on make all.
3273 - Fix 5011 auto-trust-anchor-file initial read to skip RRSIGs.
3274 - --enable-checking: enables assertions but does not look nonproduction.
3275 - nicer VERB_DETAIL (verbosity 2, unbound-host -d) output, with
3276 nxdomain and nodata distinguished.
3277 - ldns tarball updated.
3278 - --disable-rpath fixed for libtool not found errors.
3279 - new fedora specfile from Fedora13 in contrib from Paul Wouters.
3281 26 February 2010: Wouter
3282 - Fixup prototype for lexer cleanup in daemon code.
3283 - unbound-control list_stubs, list_forwards, list_local_zones and
3286 24 February 2010: Wouter
3287 - Fix scrubber bug that potentially let NS records through. Reported
3289 - Also delete potential poison references from additional.
3290 - Fix: no classification of a forwarder as lame, throw away instead.
3292 23 February 2010: Wouter
3293 - libunbound ub_ctx_get_option() added.
3294 - unbound-control set_option and get_option commands.
3295 - iana portlist updated.
3297 18 February 2010: Wouter
3298 - A little more strict DS scrubbing.
3299 - No more blacklisting of unresponsive servers, a 2 minute timeout
3301 - RD flag not enabled for dnssec-blacklisted tries, unless necessary.
3302 - pickup ldns compile fix, libdl for libcrypto.
3303 - log 'tcp connect: connection timed out' only in high verbosity.
3304 - unbound-control log_reopen command.
3305 - moved get_option code from unbound-checkconf to util/config_file.c
3307 17 February 2010: Wouter
3308 - Disregard DNSKEY from authority section for chain of trust.
3309 DS records that are irrelevant to a referral scrubbed. Anti-poison.
3310 - iana portlist updated.
3312 16 February 2010: Wouter
3313 - Check for 'no space left on device' (or other errors) when
3314 writing updated autotrust anchors and print errno to log.
3316 15 February 2010: Wouter
3317 - Fixed the requery protection, the TTL was 0, it is now 900 seconds,
3318 hardcoded. We made the choice to send out more conservatively,
3319 protecting against an aggregate effect more than protecting a
3320 single user (from their own folly, perhaps in case of misconfig).
3322 12 February 2010: Wouter
3323 - Re-query pattern changed on validation failure. To protect troubled
3324 authority servers, unbound caches a failure for the DNSKEY or DS
3325 records for the entire zone, and only retries that 900 seconds later.
3326 This implies that only a handful of packets are sent extra to the
3327 authority if the zone fails.
3329 11 February 2010: Wouter
3330 - ldns tarball update for long label length syntax error fix.
3331 - iana portlist updated.
3333 9 February 2010: Wouter
3334 - Fixup in compat snprintf routine, %f 1.02 and %g support.
3335 - include math.h for testbound test compile portability.
3337 2 February 2010: Wouter
3338 - Updated url of IANA itar, interim trust anchor repository, in script.
3340 1 February 2010: Wouter
3341 - iana portlist updated.
3342 - configure test for memcmp portability.
3344 27 January 2010: Wouter
3345 - removed warning on format string in validator error log statement.
3346 - iana portlist updated.
3348 22 January 2010: Wouter
3349 - libtool finish the install of unbound python dynamic library.
3351 21 January 2010: Wouter
3352 - acx_nlnetlabs.m4 synchronised with nsd's version.
3354 20 January 2010: Wouter
3355 - Fixup lookup trouble for parent-child domains on the first query.
3357 14 January 2010: Wouter
3358 - Fixup ldns detection to also check for header files.
3360 13 January 2010: Wouter
3361 - prefetch-key option that performs DNSKEY queries earlier in the
3362 validation process, and that could halve the latency on DNSSEC
3363 queries. It takes some extra processing (CPU, a cache is needed).
3365 12 January 2010: Wouter
3366 - Fix unbound-checkconf for auto-trust-anchor-file present checks.
3368 8 January 2010: Wouter
3369 - Fix for parent-child disagreement code which could have trouble
3370 when (a) ipv6 was disabled and (b) the TTL for parent and child
3371 were different. There were two bugs, the parent-side information
3372 is fixed to no longer block lookup of child side information and
3373 the iterator is fixed to no longer attempt to get ipv6 when it is
3374 not enabled and then give up in failure.
3375 - test and fixes to make prefetch actually store the answer in the
3376 cache. Considers some rrsets 'already expired' but does not allow
3377 overwriting of rrsets considered more secure.
3379 7 January 2010: Wouter
3380 - Fixup python documentation (thanks Leo Vandewoestijne).
3381 - Work on cache prefetch feature.
3382 - Stats for prefetch, in log print stats, unbound-control stats
3383 and in unbound_munin plugin.
3385 6 January 2010: Wouter
3386 - iana portlist updated.
3387 - bug#291: DNS wireformat max is 255. dname_valid allowed 256 length.
3388 - verbose output includes parent-side-address notion for lameness.
3389 - documented val-log-level: 2 setting in example.conf and man page.
3390 - change unbound-control-setup from 1024(sha1) to 1536(sha256).
3392 1 January 2010: Wouter
3393 - iana portlist updated.
3395 22 December 2009: Wouter
3396 - configure with newer libtool 2.2.6b.
3398 17 December 2009: Wouter
3401 - trunk to version 1.4.2.
3403 15 December 2009: Wouter
3404 - Answer to qclass=ANY queries, with class IN contents.
3405 Test that validation also works.
3406 - updated ldns snapshot tarball with latest fixes (parsing records).
3408 11 December 2009: Wouter
3409 - on IPv4 UDP turn off DF flag.
3411 10 December 2009: Wouter
3412 - requirements.txt updated with design choice explanations.
3413 - Reading fixes: fix to set unlame when child confirms parent glue,
3414 and fix to avoid duplicate addresses in delegation point.
3415 - verify_rrsig routine checks expiration last.
3417 9 December 2009: Wouter
3418 - Fix Bug#287(reopened): update of ldns tarball with fix for parse
3419 errors generated for domain names like '.example.com'.
3420 - Fix SOA excluded from negative DS responses. Reported by Hauke
3421 Lampe. The negative cache did not include proper SOA records for
3422 negative qtype DS responses which makes BIND barf on it, such
3423 responses are now only used internally.
3424 - Fix negative cache lookup of closestencloser check of DS type bit.
3426 8 December 2009: Wouter
3427 - Fix for lookup of parent-child disagreement domains, where the
3428 parent-side glue works but it does not provide proper NS, A or AAAA
3429 for itself, fixing domains such as motorcaravanners.eu.
3430 - Feature: you can specify a port number in the interface: line, so
3431 you can bind the same interface multiple times at different ports.
3433 7 December 2009: Wouter
3434 - Bug#287: Fix segfault when unbound-control remove nonexistent local
3435 data. Added check to tests.
3437 1 December 2009: Wouter
3438 - Fix crash with module-config "iterator".
3439 - Added unit test that has "iterator" module-config.
3441 30 November 2009: Wouter
3442 - bug#284: fix parse of # without end-of-line at end-of-file.
3444 26 November 2009: Wouter
3445 - updated ldns with release candidate for version 1.6.3.
3446 - tag for 1.4.0 release.
3447 - 1.4.1 version in trunk.
3448 - Fixup major libtool version to 2 because of why_bogus change.
3449 It was 1:5:0 but should have been 2:0:0.
3451 23 November 2009: Wouter
3452 - Patch from David Hubbard for libunbound manual page.
3453 - Fixup endless spinning in unbound-control stats reported by
3454 Attila Nagy. Probably caused by clock reversal.
3456 20 November 2009: Wouter

3480 - iana portlist updated.
3481 - fix manpage errors reported by debian lintian.
3483 - fixup very long vallog2 level error strings.
3485 11 November 2009: Wouter
3486 - ldns tarball updated (to 1.6.2).
3489 10 November 2009: Wouter
3490 - Thanks to Surfnet found bug in new dnssec-retry code that failed
3491 to combine well when combined with DLV and a particular failure.
3492 - Fixed unbound-control -h output about argument optionality.
3495 5 November 2009: Wouter
3496 - lint fixes and portability tests.
3497 - better error text for multiple domain keys in one autotrust file.
3499 2 November 2009: Wouter
3500 - Fix bug where autotrust does not work when started with a DS.

3512 - RFC 5702: RSASHA256 and RSASHA512 support enabled by default.
3513 - ldns tarball updated (which also enables rsasha256 support).
3515 27 October 2009: Wouter
3516 - iana portlist updated.
3518 8 October 2009: Wouter
3520 - add val-log-level print to corner case (nameserver.epost.bg).
3521 - more detail to errors from insecure delegation checks.
3522 - Fix double time subtraction in negative cache reported by
3523 Amanda Constant and Hugh Mahon.
3524 - Made new validator error string available from libunbound for
3525 applications. It is in result->why_bogus, a zero-terminated string.

3527 Also the errinf is public in module_qstate (for other modules).
3529 7 October 2009: Wouter
3530 - retry for validation failure in DS and prime results. Less mem use.

3538 - moved version number to 1.4.0 because of 1.3.4 release with only
3539 the NSEC3 patch from the entry above.
3540 - val-log-level: 2 shows extended error information for validation
3541 failures, but still one (longish) line per failure. For example:
3542 validation failure <example.com. DNSKEY IN>: signature expired from
3543 192.0.2.4 for trust anchor example.com. while building chain of trust
3544 validation failure <www.example.com. A IN>: no signatures from
3545 192.0.2.6 for key example.com. while building chain of trust
3547 6 October 2009: Wouter
3548 - Test set updated to provide additional ns lookup result.
3549 The retry would attempt to fetch the data from other nameservers
3550 for bogus data, and this needed to be provisioned in the tests.

3567 25 September 2009: Wouter
3568 - so-rcvbuf: 4m option added. Set this on large busy servers to not
3569 drop the occasional packet in spikes due to full socket buffers.
3570 netstat -su keeps a counter of UDP dropped due to full buffers.
3571 - review of validator/autotrust.c, small fixes and comments.
3573 23 September 2009: Wouter
3574 - 5011 query failed counts verification failures, not lookup failures.
3575 - 5011 probe failure handling fixup.
3576 - test unbound reading of original autotrust data.
3577 The metadata per-key, such as key state (PENDING, MISSING, VALID) is
3578 picked up, otherwise performs initial probe like usual.
3580 22 September 2009: Wouter
3581 - autotrust test with algorithm rollover, new ordering of checks
3582 assists in orderly rollover.
3583 - autotrust test with algorithm rollover to unknown algorithm.
3584 checks if new keys are supported before adding them.
3585 - autotrust test with trust point revocation, becomes unsigned.

3587 for qtype DNSKEY (assumes DNSKEY occurs at zone apex).
3589 18 September 2009: Wouter
3590 - autotrust tests, fix trustpoint timer deletion code.
3591 fix count of valid anchors during missing remove.

3606 10 September 2009: Wouter
3607 - increased MAXSYSLOGLEN so .bg key can be printed in debug output.
3608 - use linebuffering for log-file: output, this can be significantly
3609 faster than the previous fflush method and enable some class of
3610 resolvers to use high verbosity (for short periods).
3611 Not on windows, because line buffering does not work there.
3613 9 September 2009: Wouter
3614 - Fix bug where DNSSEC-bogus messages were marked with too high TTL.
3615 The RRsets would still expire at the normal time, but this would
3616 keep messages bogus in the cache for too long.
3617 - regression test for that bug.
3618 - documented that load_cache is meant for debugging.
3620 8 September 2009: Wouter
3621 - fixup printing errors when load_cache, they were printed to the
3622 SSL connection which broke, now to the log.

3632 - Changes to make unbound work with libevent-2.0.3 alpha. (in
3633 configure detection due to new ssl dependency in libevent)
3634 - do not call sphinx for documentation when python is disabled.
3635 - remove EV_PERSIST from libevent timeout code to make the code
3636 compatible with the libevent-2.0. Works with older libevent too.

3705 14 August 2009: Wouter
3706 - unbound-control lookup prints out infra cache information, like RTT.
3707 - Fix bug in DLV lookup reported by Amanda from Secure64.
3708 It could sometimes wrongly classify a domain as unsigned, which
3709 does not give the AD bit on replies.

3831 18 June 2009: Wouter
3832 - Fix of message parse bug where (specifically) an NSEC and RRSIG
3833 in the wrong order would be parsed, but put wrongly into internal
3834 structures so that later validation would fail.
3835 - Extreme lenience for wrongly truncated replies where a positive

3837 turned into minimal responses with only the (secure) answer.
3838 - autoconf 2.63 for configure.
3839 - python warnings suppress. Keep python API away from header files.
3841 17 June 2009: Wouter

3846 - Fixup opportunistic target query generation to it does not
3847 generate queries that are known to fail.
3848 - Touchup on munin total memory report.
3849 - messages picked out of the cache by the iterator are checked
3850 if their cname chain is still correct and if validation status
3851 has to be reexamined.
3853 15 June 2009: Wouter
3854 - iana portlist updated.
3856 14 June 2009: Wouter
3857 - Fixed bug where cached responses would lose their security
3858 status on second validation, which especially impacted dlv
3859 lookups. Reported by Hauke Lampe.
3861 13 June 2009: Wouter
3862 - bug #254. removed random whitespace from example.conf.
3864 12 June 2009: Wouter
3865 - Fixup potential wrong NSEC picked out of the cache.
3866 - If unfulfilled callbacks are deleted they are called with an error.
3867 - fptr wlist checks for mesh callbacks.
3868 - fwd above stub in configuration works.
3870 11 June 2009: Wouter
3871 - Fix queries for type DS when forward or stub zones are there.
3872 They are performed to higherup domains, and thus treated as if
3873 going to higher zones when looking up the right forward or stub
3874 server. This makes a stub pointing to a local server that has
3875 a local view of example.com signed with the same keys as are
3876 publicly used work. Reported by Johan Ihren.
3877 - Added build-unbound-localzone-from-hosts.pl to contrib, from
3878 Dennis DeDonatis. It converts /etc/hosts into config statements.
3879 - same thing fixed for forward-zone and DS, chain of trust from
3880 public internet into the forward-zone works now. Added unit test.
3883 - openssl key files are opened apache-style, when user is root and
3884 before chrooting. This makes permissions on remote-control key
3885 files easier to set up. Fixes bug #251.
3886 - flush_type and flush_name remove msg cache entries.
3887 - codereview - dp copy bogus setting fix.
3890 - Removed RFC5011 REVOKE flag support. Partial 5011 support may cause
3891 inadvertant behaviour.
3892 - 1.3.0 tarball for release created.
3893 - 1.3.1 development in svn trunk.
3894 - iana portlist updated.
3895 - fix lint from complaining on ldns/sha.h.
3896 - help compiler figure out aliasing in priv_rrset_bad() routine.
3897 - fail to configure with python if swig is not found.
3898 - unbound_munin_ in contrib uses ps to show rss if sbrk does not work.
3901 - fixup bad free() when wrongly encoded DSA signature is seen.
3902 Reported by Paul Wouters.
3903 - review comments from Matthijs.
3906 - --enable-sha2 option. The draft rsasha256 changed its algorithm
3907 numbers too often. Therefore it is more prudent to disable the
3908 RSASHA256 and RSASHA512 support by default.
3909 - ldns trunk included as new tarball.
3910 - recreated the 1.3.0 tag in svn. rc1 tarball generated at this point.
3913 - fixup doc bug in README reported by Matthew Dempsky.
3916 - update iana port list
3917 - update ldns lib tarball
3920 - detect lack of IPv6 support on XP (with a different error code).
3921 - Fixup a crash-on-exit which was triggered by a very long queue.
3922 Unbound would try to re-use ports that came free, but this is
3923 of course not really possible because everything is deleted.
3924 Most easily triggered on XP (not Vista), maybe because of the
3925 network stack encouraging large messages backlogs.
3926 - change in debug statements.
3927 - Fixed bug that could cause a crash if root prime failed when there
3928 were message backlogs.
3931 - Thanks again to Brett Carr, found an assertion that was not true.
3932 Assertion checked if recursion parent query still existed.
3934 29 April 2009: Wouter
3935 - Thanks to Brett Carr, caught windows resource leak, use
3936 closesocket() and not close() on sockets or else the network stack
3937 starts to leak handles.
3938 - Removed usage of windows Mutex because windows cannot handle enough
3939 mutexes open. Provide own mutex implementation using primitives.

3990 - windows compile fix.
3991 - Detect FreeBSD jail without ipv6 addresses assigned.
3992 - python libunbound wrapper unit test.

3997 /usr/lib/python2.x/site-packages/unbound.py
3998 /usr/lib/python2.x/site-packages/_unbound.so*
3999 The example python scripts (pythonmod/examples and
4000 libunbound/python/examples) are not installed.

4017 NXDOMAIN messages which could remain in the cache regardless.
4018 - python module test package.
4020 1 April 2009: Wouter
4021 - suppress errors when trying to contact authority servers that gave

4079 - Added tests, unknown algorithms become insecure. fallback works.
4080 - Fix for and test for unknown algorithms in a trust anchor
4081 definition. Trust anchors with no supported algos are ignored.
4082 This means a (higher)DS or DLV entry for them could succeed, and
4083 otherwise they are treated as insecure.
4084 - domain-insecure: "example.com" statement added. Sets domain
4085 insecure regardless of chain of trust DSs or DLVs. The inverse
4088 17 March 2009: Wouter

4114 - install and service with log to file works on XP and Vista on
4115 default install location.
4116 - on windows logging to the Application logbook works (as a service).
4117 - fix RUN_DIR on windows compile setting in makedist.
4118 - windows registry has Software\Unbound\ConfigFile element.

4168 have unsupported algorithms.
4169 - added contrib/update-itar.sh This script is similar to
4170 update-anchor.sh, and updates from the IANA ITAR repository.
4171 You can provide your own PGP key and trust repo, or can use the
4172 builtin. The program uses wget and gpg to work.
4173 - iana portlist updated.
4174 - update-itar.sh: using ftp:// urls because https godaddy certificate
4175 is not available everywhere and then gives fatal errors. The
4176 security is provided by pgp signature.
4178 18 February 2009: Wouter
4179 - more cycle detection. Also for target queries.
4180 - fixup bug where during deletion of the mesh queries the callbacks
4181 that were reentrant caused assertion failures. Keep the mesh in
4182 a reentrant safe state. Affects libunbound, reload of server,
4183 on quit and flush_requestlist.
4184 - iana portlist updated.
4186 13 February 2009: Wouter

4204 10 February 2009: Wouter
4205 - keys with rfc5011 REVOKE flag are skipped and not considered when
4207 - iana portlist updated
4208 - #226: dump_requestlist feature for unbound-control.
4210 6 February 2009: Wouter
4211 - contrib contains specfile for fedora 1.2.1 (from Paul Wouters).

4213 - fixup EOL in include directive (reported by Paul Wouters).
4214 You can no longer specify newlines in the names of included files.
4215 - config parser changed. Gives some syntax errors closer to where they
4216 occurred. Does not enforce a space after keyword anymore.
4217 Does not allow literal newlines inside quoted strings anymore.
4218 - verbosity level 5 logs customer IP for new requestlist entries.
4219 - test fix, lexer and cancel test.
4220 - new option log-time-ascii: yes if you enable it prints timestamps
4221 in the log file as Feb 06 13:45:26 (like syslog does).
4222 - detect event_base_new in libevent-1.4.1 and later and use it.
4223 - #231 unbound-checkconf -o option prints that value from config file.
4224 Useful for scripting in management scripts and the like.
4226 5 February 2009: Wouter
4227 - ldns 1.5.0 rc as tarball included.
4228 - 1.3.0 development continues:
4229 change in libunbound API: ub_cancel can return an error, that
4230 the async_id did not exist, or that it was already delivered.
4231 The result could have been delivered just before the cancel
4232 routine managed to acquire the lock, so a caller may get the
4233 result at the same time they call cancel. For this case,
4234 ub_cancel tries to return an error code.
4235 Fixes race condition in ub_cancel() libunbound function.
4236 - MacOSX Leopard cleaner text output from configure.
4237 - initgroups(3) is called to drop secondary group permissions, if
4239 - configure option --with-ldns-builtin forces the use of the
4240 inluded ldns package with the unbound source. The -I include
4241 is put before the others, so it avoids bad include files from
4242 an older ldns install.
4243 - daemon(3) posix call is used when available.
4244 - testbound test for older fix added.
4246 4 February 2009: Wouter
4247 - tag for release 1.2.1.
4248 - trunk setup for 1.3.0 development.

4253 - updated IANA portlist.
4255 16 January 2009: Wouter
4256 - more quiet about ipv6 network failures, i.e. when ipv6 is not
4257 available (network unreachable). Debug still printed on high
4259 - unbound-host -4 and -6 options. Stops annoying ipv6 errors when
4260 debugging with unbound-host -4 -d ...
4261 - more cycle detection for NS-check, addr-check, root-prime and
4262 stub-prime queries in the iterator. Avoids possible deadlock
4265 15 January 2009: Wouter
4266 - bug #229: fixup configure checks for compilation with Solaris
4267 Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc
4268 - fixup suncc warnings.
4269 - fix bug where unbound could crash using libevent 1.3 and older.
4270 - update testset for recent retry change.
4272 14 January 2009: Wouter
4273 - 1.2.1 feature: negative caching for failed queries.
4274 Queries that failed are cached for 5 seconds (NORR_TTL).
4275 If the failure is local, like out of memory, it is not cached.
4276 - the TTL comparison for the cache used different comparisons,
4277 causing many cache responses that used the iterator and validator
4278 state machines unnecessarily.
4279 - retry from 4 to 5 so that EDNS drop retry is part of the first
4280 query resolve attempt, and cached error does not stop EDNS fallback.
4281 - remove debug prints that protect against bad referrals.
4282 - honor QUIET=no on make commandline (or QUIET=yes ).
4284 13 January 2009: Wouter

4290 are in the negative cache.
4292 12 January 2009: Wouter
4293 - fixed bug in infrastructure lameness cache, did not lowercase
4294 name of zone to hash when setting lame.
4295 - lameness debugging printouts.
4297 9 January 2009: Wouter

4305 bug #224, building with -j race condition.
4306 - remove possible race condition in the test for race conditions.
4308 7 January 2009: Wouter
4309 - version 1.2.0 in preparation.
4310 - feature to allow wildcards (*, ?, [], {}. ~) in trusted-keys-file
4311 statements. (Adapted from patch by Paul Wouters).
4312 - typo fix and iana portlist updated.
4313 - porting testsuite; unused var warning, and type fixup.
4315 6 January 2009: Wouter
4316 - fixup packet-of-death when compiled with --enable-debug.
4317 A malformed packet could cause an internal assertion failure.
4318 - added test for HINFO canonicalisation behaviour.
4319 - fixup reported problem with transparent local-zone data where
4320 queries with different type could get nxdomain. Now queries
4321 with a different name get resolved normally, with different type
4322 get a correct NOERROR/NODATA answer.
4323 - HINFO no longer downcased for validation, making unbound compatible
4325 - fix reading included config files when chrooted.
4326 Give full path names for include files.
4327 Relative path names work if the start dir equals the working dir.
4328 - fix libunbound message transport when no packet buffer is available.
4330 5 January 2009: Wouter
4331 - fixup getaddrinfo failure handling for remote control port.
4332 - added L.ROOT-SERVERS.NET. AAAA 2001:500:3::42 to builtin root hints.
4333 - fixup so it works with libev-3.51 from http://dist.schmorp.de/libev/
4334 - comm_timer_set performs base_set operation after event_add.
4336 18 December 2008: Wouter
4337 - fixed bug reported by Duane Wessels: error in DLV lookup, would make
4338 some zones that had correct DLV keys as insecure.
4339 - follows -rc makedist from ldns changes (no _rc).
4340 - ldns tarball updated with 1.4.1rc for DLV unit test.
4341 - verbose prints about recursion lame detection and server selection.
4342 - fixup BSD port for infra host storage. It hashed wrongly.
4343 - fixup makedist snapshot name generation.
4344 - do not reopen syslog to avoid dev/log dependency.
4346 17 December 2008: Wouter
4347 - follows ldns makedist.sh. -rc option. autom4te dir removed.
4348 - unbound-control status command.
4349 - extended statistics has a number of ipv6 queries counter.
4350 contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
4352 16 December 2008: Wouter
4353 - follow makedist improvements from ldns, for maintainers prereleases.
4354 - snapshot version uses _ not - to help rpm distinguish the
4357 11 December 2008: Wouter
4358 - better fix for bug #219: use LOG_NDELAY with openlog() call.
4359 Thanks to Tamas Tevesz.
4361 9 December 2008: Wouter
4362 - bug #221 fixed: unbound checkconf checks if key files exist if
4363 remote control is enabled. Also fixed NULL printf when not chrooted.
4364 - iana portlist updated.
4366 3 December 2008: Wouter
4367 - Fix problem reported by Jaco Engelbrecht where unbound-control stats
4368 freezes up unbound if this was compiled without threading, and
4369 was using multiple processes.
4370 - iana portlist updated.
4371 - test for remote control with interprocess communication.
4372 - created command distribution mechanism so that remote control
4373 commands other than 'stats' work on all processes in a nonthreaded
4374 compiled version. dump/load cache work, on the first process.
4375 - fixup remote control local_data addition memory corruption bug.
4377 1 December 2008: Wouter
4378 - SElinux policy files in contrib/selinux for the unbound daemon,
4379 by Paul Wouters and Adam Tkac.
4381 25 November 2008: Wouter

4383 - skip unsupported feature tests on vista/mingw.
4384 - fixup testcode/streamtcp to work on vista/mingw.
4385 - root-hints test checks version of dig required.
4386 - blacklisted servers are polled at a low rate (1%) to see if they
4387 come back up. But not if there is some other working server.
4389 24 November 2008: Wouter
4390 - document that the user of the server daemon needs read privileges
4391 on the keys and certificates generated by unbound-control-setup.
4392 This is different per system or distribution, usually, running the
4393 script under the same username as the server uses suffices.
4394 i.e. sudo -u unbound unbound-control-setup
4395 - testset port to vista/mingw.
4396 - tcp_sigpipe to freebsd port.
4398 21 November 2008: Wouter
4399 - fixed tcp accept, errors were printed when they should not.
4400 - unbound-control-setup.sh removes read/write permissions other
4401 from the keys it creates (as suggested by Dmitriy Demidov).
4403 20 November 2008: Wouter
4404 - fixup fatal error due to faulty error checking after tcp accept.
4405 - add check in rlimit to avoid integer underflow.
4406 - rlimit check with new formula; better estimate for number interfaces
4407 - nicer comments in rlimit check.
4408 - tag 1.1.1 created in svn.
4409 - trunk label is 1.1.2
4411 19 November 2008: Wouter
4412 - bug #219: fixed so that syslog which delays opening until the first

4420 - in 1.1.1; make clean nicer. grammar in manpage.
4422 17 November 2008: Wouter
4423 - theoretical fix for problems reported on mailing list.
4424 If a delegation point has no A but only AAAA and do-ip6 is no,
4425 resolution would fail. Fixed to ask for the A and AAAA records.
4426 It has to ask for both always, so that it can fail quietly, from
4427 TLD perspective, when a zone is only reachable on one transport.
4428 - test for above, only AAAA and doip6 is no. Fix causes A record
4429 for nameserver to be fetched.
4430 - fixup address duplication on cache fillup for delegation points.
4431 - testset updated for new query answer requirements.
4433 14 November 2008: Wouter

4446 12 November 2008: Wouter
4447 - add unbound-control manpage to makedist replace list.
4449 11 November 2008: Wouter
4450 - unit test for negative cache, stress tests the refcounting.
4451 - fix for refcounting error that could cause fptr_wlist fatal exit
4452 in the negative cache rbtree (upcoming 1.1 feature). (Thanks to
4453 Attila Nagy for testing).
4454 - nicer comments in cachedump about failed RR to string conversion.

4472 5 November 2008: Wouter
4473 - fixed possible memory leak in key_entry_key deletion.
4474 Would leak a couple bytes when trust anchors were replaced.
4475 - if query and reply qname overlap, the bytes are skipped not copied.
4476 - fixed file descriptor leak when messages were jostled out that
4477 had outstanding (TCP) replies.
4478 - DNAMEs used from cache have their synthesized CNAMEs initialized
4480 - fixed file descriptor leak for localzone type deny (for TCP).
4481 - fixed memleak at exit for nsec3 negative cached zones.
4482 - fixed memleak for the keyword 'nodefault' when reading config.
4483 - made verbosity of 'edns incapable peer' warning higher, so you
4484 do not get spammed by it.
4485 - caught elusive Bad file descriptor error bug, that would print the
4486 error while unnecessarily try to listen to a closed fd. Fixed.
4488 4 November 2008: Wouter
4489 - fixed -Wwrite-strings warnings that result in better code.
4491 3 November 2008: Wouter

4499 - proper detection of SHA256 and SHA512 functions (not just sizes).
4501 23 October 2008: Wouter
4502 - a little more debug info for failure on signer names. prints names.
4504 22 October 2008: Wouter
4505 - CFLAGS are picked up by configure from the environment.
4506 - iana portlist updated.
4507 - updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
4508 - new stub-prime: yesno option. Default is off, so it does not prime.
4509 can be turned on to get same behaviour as previous unbound release.
4510 - made automated test that checks if builtin root hints are uptodate.
4511 - finished draft-wijngaards-dnsext-resolver-side-mitigation
4512 implementation. The unwanted-reply-threshold can be set.
4513 - fixup so fptr_whitelist test in alloc.c works.
4515 21 October 2008: Wouter
4516 - fix update-anchors.sh, so it does not report different RR order
4517 as an update. Sorts the keys in the file. Updated copyright.
4518 - fixup testbound on windows, the command control pipe doesn't exist.
4519 - skip 08hostlib test on windows, no fork() available.
4520 - made unbound-remote work on windows.
4522 20 October 2008: Wouter
4523 - quench a log message that is debug only.
4524 - iana portlist updated.
4525 - do not query bogus nameservers. It is like nameservers that have
4526 the NS or A or AAAA record bogus are listed as donotquery.
4527 - if server selection is faced with only bad choices, it will
4528 attempt to get more options to be fetched.
4529 - changed bogus-ttl default value from 900 to 60 seconds.
4530 In anticipation that operator caused failures are more likely than
4531 actual attacks at this time. And thus repeated validation helps
4532 the operators get the problem fixed sooner. It makes validation
4533 failures go away sooner (60 seconds after the zone is fixed).
4534 Also it is likely to try different nameserver targets every minute,
4535 so that if a zone is bad on one server but not another, it is
4536 likely to pick up the 'correct' one after a couple minutes,
4537 and if the TTL is big enough that solves validation for the zone.
4538 - fixup unbound-control compilation on windows.
4540 17 October 2008: Wouter
4541 - port Leopard/G5: fixup type conversion size_t/uint32.

4545 and attemps to validate the entries.
4547 16 October 2008: Wouter
4548 - Fixup negative TTL values appearing (reported by Attila Nagy).
4550 15 October 2008: Wouter
4551 - better documentation for 0x20; remove fallback TODO, it is done.

4553 as well as very careful NS caching (only when doing NS query).
4554 A, AAAA use the delegation from the NS-query.
4556 14 October 2008: Wouter
4557 - fwd_three.tpkg test was flaky. If the three requests hit the
4558 wrong threads by chance (or bad OS) then the test would fail.
4559 Made less flaky by increasing number of retries.
4560 - stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
4561 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
4562 Which includes the ldns_dname_absolute fix.
4563 - fwd_three test remains flaky now that unbound does not stop
4564 listening when full. Thus, removed timeout problem.
4565 It may be serviced by three threads, or maybe by one.
4566 Mostly only useful for lock-check testing now.
4568 13 October 2008: Wouter
4569 - fixed recursion servers deployed as authoritative detection, so
4570 that as a last resort, a +RD query is sent there to get the
4572 - iana port list update.
4573 - ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).

4597 so, update-anchor.sh -d mydir && /etc/rc.d/unbound restart
4598 can restart unbound exactly when needed.
4600 30 September 2008: Wouter
4601 - fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
4602 - tests for sha256 support and downgrade resistance.

4604 using the drafted protocol numbers.
4605 - when using stub on localhost (127.0.0.1@10053) unbound works.
4606 Like when running NSD to host a local zone, on the same machine.
4607 The noprime feature. manpages more explanation. Added a test for it.
4608 - shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
4610 29 September 2008: Wouter
4611 - EDNS lameness detection, if EDNS packets are dropped this is

5034 - requirements doc, updated clean query returns.
5035 - parseunbound.pl update from Kai Storbeck.
5036 - sunos4 porting changes.
5038 15 April 2008: Wouter
5039 - fixup default rc.d pidfile location to /usr/local/etc.
5040 - iana ports updated.
5041 - copyright updated in ldns-testpkts to keep same as in ldns.
5042 - fixup checkconf chroot tests a bit more, chdir must be inside
5044 - documented 'gcc: unrecognized -KPIC option' errors on Solaris.
5045 - example.conf values changed to /usr/local/etc/unbound
5047 - DSA signatures: unbound is compatible with both encodings found.
5048 It will detect and convert when necessary.
5050 14 April 2008: Wouter
5051 - got update for parseunbound.pl statistics script from Kai Storbeck.
5052 - tpkg tests for udp wait list.
5053 - documented 0x20 status.
5054 - fixup chroot and checkconf, it is much smarter now.
5055 - fixup DSA EVP signature decoding. Solution that Jelte found copied.
5056 - and check first sig byte for the encoding type.
5058 11 April 2008: Wouter
5059 - random port selection out of the configged ports.
5060 - fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
5061 - removed base_port.
5062 - created 256-port ephemeral space for the OS, 59802 available.
5063 - fixup consistency of port_if out array during heavy use.
5065 10 April 2008: Wouter
5066 - --with-libevent works with latest libevent 1.4.99-trunk.
5067 - added log file statistics perl script to contrib.
5068 - automatic iana ports update from makefile. 60058 available.
5070 9 April 2008: Wouter
5071 - configure can detect libev(from its build directory) when passed
5072 --with-libevent=/home/wouter/libev-3.2
5073 libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
5074 - unused commpoints not listed in epoll list.
5075 - statistics-cumulative option so that the values are not reset.
5076 - config creates array of available ports, 61841 available,
5077 it excludes <1024 and iana assigned numbers.
5078 config statements to modify the available port numbers.
5080 8 April 2008: Wouter
5081 - unbound tries to set the ulimit fds when started as server.
5082 if that does not work, it will scale back its requirements.
5084 27 March 2008: Wouter
5085 - documented /dev/random symlink from chrootdir as FAQ entry.
5087 26 March 2008: Wouter
5088 - implemented AD bit signaling. If a query sets AD bit (but not DO)
5089 then the AD bit is set in the reply if the answer validated.
5090 Without including DNSSEC signatures. Useful if you have a trusted
5091 path from the client to the resolver. Follows dnssec-updates draft.
5093 25 March 2008: Wouter
5094 - implemented check that for NXDOMAIN and NOERROR answers a query
5095 section must be present in the reply (by the scrubber). And it must
5096 be equal to the question sent, at least lowercase folded.
5097 Previously this feature happened because the cache code refused
5098 to store such messages. However blocking by the scrubber makes
5099 sure nothing gets into the RRset cache. Also, this looks like a
5100 timeout (instead of an allocation failure) and this retries are
5101 done (which is useful in a spoofing situation).
5102 - RTT banding. Band size 400 msec, this makes band around zero (fast)
5103 include unknown servers. This makes unbound explore unknown servers.
5105 7 March 2008: Wouter
5106 - -C config feature for harvest program.
5107 - harvest handles CNAMEs too.
5109 5 March 2008: Wouter
5110 - patch from Hugo Koji Kobayashi for iterator logs spelling.
5112 4 March 2008: Wouter
5113 - From report by Jinmei Tatuya, rfc2181 trust value for remainder
5114 of a cname trust chain is lower; not full answer_AA.
5115 - test for this fix.
5116 - default config file location is /usr/local/etc/unbound.
5117 Thus prefix is used to determine the location. This is also the
5118 chroot and pidfile default location.
5120 3 March 2008: Wouter
5121 - Create 0.10 svn tag.
5122 - 0.11 version in trunk.
5123 - indentation nicer.
5125 29 February 2008: Wouter
5126 - documentation update.
5127 - fixup port to Solaris of perf test tool.
5128 - updated ldns-tarball with decl-after-statement fixes.
5130 28 February 2008: Wouter
5131 - fixed memory leaks in libunbound (during cancellation and wait).
5132 - libunbound returns the answer packet in full.
5133 - snprintf compat update.
5134 - harvest performs lookup.
5135 - ldns-tarball update with fix for ldns_dname_label.
5136 - installs to sbin by default.
5137 - install all manual pages (unbound-host and libunbound too).
5139 27 February 2008: Wouter
5140 - option to use caps for id randomness.
5141 - config file option use-caps-for-id: yes
5142 - harvest debug tool
5144 26 February 2008: Wouter
5145 - delay utility delays TCP as well. If the server that is forwarded
5146 to has a TCP error, the delay utility closes the connection.
5147 - delay does REUSE_ADDR, and can handle a server that closes its end.
5148 - answers use casing from query.
5150 25 February 2008: Wouter
5151 - delay utility works. Gets decent thoughput too (>20000).
5153 22 February 2008: Wouter
5154 - +2% for recursions, if identical queries (except for destination
5155 and query ID) in the reply list, avoid re-encoding the answer.
5156 - removed TODO items for optimizations that do not show up in
5158 - default is now minievent - not libevent. As its faster and
5159 not needed for regular installs, only for very large port ranges.
5160 - loop check different speedup pkt-dname-reading, 1% faster for
5161 nocache-recursion check.
5162 - less hashing during msg parse, 4% for recursion.
5163 - small speed fix for dname_count_size_labels, +1 or +2% recursion.
5164 - some speed results noted:
5165 optimization resulted in +40% for recursion (cache miss) and
5166 +70 to +80 for cache hits, and +96% for version.bind.
5167 zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
5168 www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
5169 www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
5170 So, unbound can be about equal qps to NSD in cache hits.
5171 And about 3.4x faster than BIND in cache performance.
5172 - delay utility for testing.
5174 21 February 2008: Wouter
5175 - speedup of root-delegation message encoding by 15%.
5176 - minor speedup of compress tree_lookup, maybe 1%.
5177 - speedup of dname_lab_cmp and memlowercmp - the top functions in
5178 profiler output, maybe a couple percent when it matters.
5180 20 February 2008: Wouter
5181 - setup speec_cache for need-ldns-testns in dotests.
5182 - check number of queued replies on incoming queries to avoid overload
5184 - fptr whitelist checks are not disabled in optimize mode.
5185 - do-daemonize config file option.
5186 - minievent time share initializes time at start.
5187 - updated testdata for nsec3 new algorithm numbers (6, 7).
5188 - small performance test of packet encoding (root delegation).
5190 19 February 2008: Wouter
5191 - applied patch to unbound-host man page from Jan-Piet Mens.
5192 - fix donotquery-localhost: yes default (it erroneously was switched
5194 - time is only gotten once and the value is shared across unbound.
5195 - unittest cleans up crypto, so that it has no memory leaks.
5196 - mini_event shares the time value with unbound this results in
5197 +3% speed for cache responses and +9% for recursions.
5198 - ldns tarball update with new NSEC3 sign code numbers.
5199 - perform several reads per UDP operation. This improves performance
5200 in DoS conditions, and costs very little in normal conditions.
5201 improves cache response +50%, and recursions +10%.
5202 - modified asynclook test. because the callback from async is not
5203 in any sort of lock (and thus can use all library functions freely),
5204 this causes a tiny race condition window when the last lock is
5205 released for a callback and a new cancel() for that callback.
5206 The only way to remove this is by putting callbacks into some
5207 lock window. I'd rather have the small possibility of a callback
5208 for a cancelled function then no use of library functions in
5209 callbacks. Could be possible to only outlaw process(), wait(),
5210 cancel() from callbacks, by adding another lock, but I'd rather not.
5212 18 February 2008: Wouter
5213 - patch to unbound-host from Jan-Piet Mens.
5214 - unbound host prints errors if fails to configure context.
5215 - fixup perf to resend faster, so that long waiting requests do
5216 not hold up the queue, they become lost packets or SERVFAILs,
5217 or can be sent a little while later (i.e. processing time may
5218 take long, but throughput has to be high).
5219 - fixup iterator operating in no cache conditions (RD flag unset
5221 - streamlined code for RD flag setting.
5222 - profiled code and changed dname compares to be faster.
5223 The speedup is about +3% to +8% (depending on the test).
5224 - minievent tests for eintr and eagain.
5226 15 February 2008: Wouter
5227 - added FreeBSD rc.d script to contrib.
5228 - --prefix option for configure also changes directory: pidfile:
5229 and chroot: defaults in config file.
5230 - added cache speed test, for cache size OK and cache too small.
5232 14 February 2008: Wouter
5233 - start without a config file (will complain, but start with
5235 - perf test program works.
5237 13 February 2008: Wouter
5239 - 1.0 development. Printout ldns version on unbound -h.
5240 - start of perf tool.
5241 - bugfix to read empty lines from /etc/hosts.
5243 12 February 2008: Wouter
5244 - fixup problem with configure calling itself if ldns-src tarball
5247 11 February 2008: Wouter
5248 - changed library to use ub_ instead of ub_val_ as prefix.
5249 - statistics output text nice.
5250 - etc/hosts handling.
5251 - library function to put logging to a stream.
5252 - set any option interface.
5254 8 February 2008: Wouter
5255 - test program for multiple queries over a TCP channel.
5256 - tpkg test for stream tcp queries.
5257 - unbound replies to multiple TCP queries on a TCP channel.
5258 - fixup misclassification of root referral with NS in answer
5259 when validating a nonrec query.
5261 - layout of manpages, spelling fix in header, manpages process by
5262 makedist, list asynclook and tcpstream tests as ldns-testns
5265 7 February 2008: Wouter
5266 - moved up all current level 2 to be level 3. And 3 to 4.
5267 to make room for new debug level 2 for detailed information
5269 - verbosity level 2. Describes recursion and validation.
5270 - cleaner configure script and fixes for libevent solaris.
5271 - signedness for log output memory sizes in high verbosity.
5273 6 February 2008: Wouter
5274 - clearer explanation of threading configure options.
5275 - fixup asynclook test for nothreading (it creates only one process
5276 to do the extended test).
5277 - changed name of ub_val_result_free to ub_val_resolve_free.
5278 - removes warning message during library linking, renamed
5279 libunbound/unbound.c -> libunbound.c and worker to libworker.
5280 - fallback without EDNS if result is NOTIMPL as well as on FORMERR.
5282 5 February 2008: Wouter
5283 - statistics-interval: seconds option added.
5284 - test for statistics option
5285 - ignore errors making directories, these can occur in parallel builds
5286 - fixup Makefile strip command and libunbound docs typo.
5288 31 January 2008: Wouter
5289 - bg thread/process reads and writes the pipe nonblocking all the time
5290 so that even if the pipe is buffered or so, the bg thread does not
5291 block, and services both pipes and queries.
5293 30 January 2008: Wouter
5294 - check trailing / on chrootdir in checkconf.
5295 - check if root hints and anchor files are in chrootdir.
5296 - no route to host tcp error is verbosity level 2.
5297 - removed unused send_reply_iov. and its configure check.
5298 - added prints of 'remote address is 1.2.3.4 port 53' to errors
5299 from netevent; the basic socket errors.
5301 28 January 2008: Wouter
5302 - fixup uninit use of buffer by libunbound (query id, flags) for
5304 - fixup uninit warning from random.c; also seems to fix sporadic
5305 sigFPE coming out of openssl.
5306 - made openssl entropy warning more silent for library use. Needs
5308 - fixup forgotten locks for rbtree_searches on ctx->query tree.
5309 - random generator cleanup - RND_STATE_SIZE removed, and instead
5310 a super-rnd can be passed at init to chain init random states.
5311 - test also does lock checks if available.
5312 - protect config access in libworker_setup().
5313 - libevent doesn't like comm_base_exit outside of runloop.
5314 - close fds after removing commpoints only (for epoll, kqueue).
5316 25 January 2008: Wouter
5317 - added tpkg for asynclook and library use.
5318 - allows localhost to be queried when as a library.
5319 - fixup race condition between cancel and answer (in case of
5320 really fast answers that beat the cancel).
5321 - please doxygen, put doxygen comment in one place.
5322 - asynclook -b blocking mode and test.
5323 - refactor asynclook, nicer code.
5324 - fixup race problems from opensll in rand init from library, with
5325 a mutex around the rand init.
5326 - fix pass async_id=NULL to _async resolve().
5327 - rewrote _wait() routine, so that it is threadsafe.
5328 - cancelation is threadsafe.
5329 - asynclook extended test in tpkg.
5330 - fixed two races where forked bg process waits for (somehow shared?)
5331 locks, so does not service the query pipe on the bg side.
5332 Now those locks are only held for fg_threads and for bg_as_a_thread.
5334 24 January 2008: Wouter
5335 - tested the cancel() function.
5336 - asynclook -c (cancel) feature.

5342 - new calls to set forwarding added to header and docs.
5344 23 January 2008: Wouter
5345 - removed debug prints from if-auto, verb-algo enables some.
5346 - libunbound QUIT setup, remove memory leaks, when using threads
5347 will share memory for passing results instead of writing it over
5348 the pipe, only writes ID number over the pipe (towards the handler
5349 thread that does process() ).
5351 22 January 2008: Wouter
5352 - library code for async in libunbound/unbound.c.
5353 - fix link testbound.
5354 - fixup exit bug in mini_event.
5355 - background worker query enter and result functions.
5356 - bg query test application asynclook, it looks up multiple
5357 hostaddresses (A records) at the same time.
5359 21 January 2008: Wouter
5360 - libworker work, netevent raw commpoints, write_msg, serialize.
5362 18 January 2008: Wouter
5363 - touch up of manpage for libunbound.
5364 - support for IP_RECVDSTADDR (for *BSD ip4).
5365 - fix for BSD, do not use ip4to6 mapping, make two sockets, once
5366 ip6 and once ip4, uses socket options.
5367 - goodbye ip4to6 mapping.
5368 - update ldns-testpkts with latest version from ldns-trunk.
5369 - updated makedist for relative ldns pathnames.
5370 - library API with more information inside the result structure.
5371 - work on background resolves.
5373 17 January 2008: Wouter
5374 - fixup configure in case -lldns is installed.
5375 - fixup a couple of doxygen warnings, about enum variables.
5376 - interface-automatic now copies the interface address from the
5377 PKT_INFO structure as well.
5378 - manual page with library API, all on one page 'man libunbound'.
5379 - rewrite of PKTINFO structure, it also captures IP4 PKTINFO.
5381 16 January 2008: Wouter
5382 - incoming queries to the server with TC bit on are replied FORMERR.
5383 - interface-automatic replied the wrong source address on localhost
5384 queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
5385 to use ifnum=-1 to mean 'no interface, use kernel route'.
5387 15 January 2008: Wouter
5388 - interface-automatic feature. experimental. Nice for anycast.
5389 - tpkg test for ip6 ancillary data.
5390 - removed debug prints.
5391 - porting experience, define for Solaris, test refined for BSD
5392 compatibility. The feature probably will not work on OpenBSD.
5393 - makedist fixup for ldns-src in build-dir.
5395 14 January 2008: Wouter
5396 - in no debug sets NDEBUG to remove asserts.
5397 - configure --enable-debug is needed for dependency generation
5398 for assertions and for compiler warnings.
5399 - ldns.tgz updated with ldns-trunk (where buffer.h is updated).
5400 - fix lint, unit test in optimize mode.
5401 - default access control allows ::ffff:127.0.0.1 v6mapped localhost.
5403 11 January 2008: Wouter
5404 - man page, warning removed.
5405 - added text describing the use of stub zones for private zones.
5406 - checkconf tests for bad hostnames (IP address), and for doubled
5408 - memory sizes can be given with 'k', 'Kb', or M or G appended.
5410 10 January 2008: Wouter
5411 - typo in example.conf.
5412 - made using ldns-src that is included the package more portable
5413 by linking with .lo instead of .o files in the ldns package.
5414 - nicer do-ip6: yes/no documentation.
5415 - nicer linking of libevent .o files.
5416 - man pages render correctly on solaris.
5418 9 January 2008: Wouter
5419 - fixup openssl RAND problem, when the system is not configured to
5420 give entropy, and the rng needs to be seeded.
5422 8 January 2008: Wouter
5423 - print median and quartiles with extensive logging.
5425 4 January 2008: Wouter
5426 - document misconfiguration in private network.
5428 2 January 2008: Wouter
5429 - fixup typo in requirements.
5430 - document that 'refused' is a better choice than 'drop' for
5431 the access control list, as refused will stop retries.
5433 7 December 2007: Wouter
5434 - unbound-host has a -d option to show what happens. This can help
5435 with debugging (why do I get this answer).
5436 - fixup CNAME handling, on nodata, sets and display canonname.
5437 - dot removed from CNAME display.
5438 - respect -v for NXDOMAINs.
5439 - updated ldns-src.tar.gz with ldns-trunk today (1.2.2 fixes).
5440 - size_t to int for portability of the header file.
5441 - fixup bogus handling.
5442 - dependencies and lint for unbound-host.
5444 6 December 2007: Wouter
5445 - library resolution works in foreground mode, unbound-host app
5447 - unbound-host prints rdata using ldns.
5448 - unbound-host accepts trust anchors, and prints validation
5449 information when you give -v.
5451 5 December 2007: Wouter
5452 - locking in context_new() inside the function.
5453 - setup of libworker.
5455 4 December 2007: Wouter
5456 - minor Makefile fixup.
5457 - moved module-stack code out of daemon/daemon into services/modstack,
5458 preparing for code-reuse.
5459 - move context into own header file.
5460 - context query structure.
5461 - removed unused variable pwd from checkconf.
5462 - removed unused assignment from outside netw.
5463 - check timeval length of string.
5464 - fixup error in val_utils getsigner.
5465 - fixup same (*var) error in netblocktostr.
5466 - fixup memleak on parse error in localzone.
5467 - fixup memleak on packet parse error.
5468 - put ; after union in parser.y.
5469 - small hardening in iter_operate against iq==NULL.
5470 - hardening, if error reply with rcode=0 (noerror) send servfail.
5471 - fixup same (*var) error in find_rrset in msgparse, was harmless.
5472 - check return value of evtimer_add().
5473 - fixup lockorder in lruhash_reclaim(), building up a list of locked
5474 entries one at a time. Instead they are removed and unlocked.
5475 - fptr_wlist for markdelfunc.
5476 - removed is_locked param from lruhash delkeyfunc.
5477 - moved bin_unlock during bin_split purely to please.
5479 3 December 2007: Wouter
5480 - changed checkconf/ to smallapp/ to make room for more support tools.
5481 (such as unbound-host).
5482 - install dirs created with -m 755 because they need to be accessible.
5483 - library extensive featurelist added to TODO.
5484 - please doxygen, lint.
5485 - library test application, with basic functionality.
5486 - fix for building in a subdirectory.
5487 - link lib fix for Leopard.
5489 30 November 2007: Wouter
5490 - makefile that creates libunbound.la, basic file or libunbound.a
5491 when creating static executables (no libtool).
5494 29 November 2007: Wouter
5495 - 0.9 public API start.
5497 28 November 2007: Wouter
5498 - Changeup plan for 0.8 - no complication needed, a simple solution
5499 has been chosen for authoritative features.
5500 - you can use single quotes in the config file, so it is possible
5501 to specify TXT records in local data.
5502 - fixup small memory problem in implicit transparent zone creation.
5503 - test for implicit zone creation and multiple RR RRsets local data.
5504 - local-zone nodefault test.
5505 - show testbound testlist on commit.
5506 - iterator normalizer changes CNAME chains ending in NXDOMAIN where
5507 the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
5509 - nicer verbosity: 0 and 1 levels.
5510 - lower nonRDquery chance of eliciting wrongly typed validation
5511 requiring message from the cache.
5512 - fix for nonRDquery validation typing; nodata is detected when
5513 SOA record in auth section (all validation-requiring nodata messages
5514 have a SOA record in authority, so this is OK for the validator),
5515 and NS record is needed to be a referral.
5516 - duplicate checking when adding NSECs for a CNAME, and test.
5517 - created svn tag 0.8, after completing testbed tests.
5519 27 November 2007: Wouter
5520 - per suggestion in rfc2308, replaced default max-ttl value with 1 day.
5521 - set size of msgparse lookup table to 32, from 1024, so that its size
5522 is below the 2048 regional large size threshold, and does not cause
5523 a call to malloc when a message is parsed.
5524 - update of memstats tool to print number of allocation calls.
5525 This is what is taking time (not space) and indicates the avg size
5526 of the allocations as well. region_alloc stat is removed.
5528 22 November 2007: Wouter
5529 - noted EDNS in-the-middle dropping trouble as a TODO.
5530 At this point theoretical, no user trouble has been reported.
5531 - added all default AS112 zones.
5532 - answers from local zone content.
5533 * positive answer, the rrset in question
5534 * nodata answer (exist, but not that type).
5535 * nxdomain answer (domain does not exist).
5536 * empty-nonterminal answer.
5537 * But not: wildcard, nsec, referral, rrsig, cname/dname,
5538 or additional section processing, NS put in auth.
5539 - test for correct working of static and transparent and couple
5540 of important defaults (localhost, as112, reverses).
5541 Also checks deny and refuse settings.
5542 - fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
5544 21 November 2007: Wouter
5545 - local zone internal data setup.
5547 20 November 2007: Wouter
5548 - 0.8 - str2list config support for double string config options.
5549 - local-zone and local-data options, config storage and documentation.
5551 19 November 2007: Wouter
5552 - do not downcase NSEC and RRSIG for verification. Follows
5553 draft-ietf-dnsext-dnssec-bis-updates-06.txt.
5554 - fixup leaking unbound daemons at end of tests.
5555 - README file updated.
5556 - nice libevent not found error.
5557 - README talks about gnu make.
5558 - 0.8: unit test for addr_mask and fixups for it.
5559 and unit test for addr_in_common().
5560 - 0.8: access-control config file element.
5561 and unit test rpl replay file.
5562 - 0.8: fixup address reporting from netevent.
5564 16 November 2007: Wouter
5565 - privilege separation is not needed in unbound at this time.
5566 TODO item marked as such.
5567 - created beta-0.7 branch for support.
5568 - tagged 0.7 for beta release.
5569 - moved trunk to 0.8 for 0.8(auth features) development.
5570 - 0.8: access control list setup.
5572 15 November 2007: Wouter
5573 - review fixups from Jelte.
5575 14 November 2007: Wouter
5576 - testbed script does not recreate configure, since its in svn now.
5577 - fixup checkconf test so that it does not test
5578 /etc/unbound/unbound.conf.
5581 13 November 2007: Wouter
5582 - remove debug print.
5583 - fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
5585 12 November 2007: Wouter
5586 - fixup signal handling where SIGTERM could be ignored if a SIGHUP
5588 - bugreports to unbound-bugs@nlnetlabs.nl
5589 - fixup testbound so it exits cleanly.
5590 - cleanup the caches on a reload, so that rrsetID numbers won't clash.
5592 9 November 2007: Wouter
5593 - took ldns snapshot in repo.
5594 - default config file is /etc/unbound/unbound.conf.
5595 If it doesn't exist, it is installed with the doc/example.conf file.
5596 The file is not deleted on uninstall.
5597 - default listening is not all, but localhost interfaces.
5599 8 November 2007: Wouter
5600 - Fixup chroot and drop user privileges.
5601 - new L root ip address in default hints.
5603 1 November 2007: Wouter
5604 - Fixup of crash on reload, due to anchors in env not NULLed after
5605 dealloc during deinit.
5606 - Fixup of chroot call. Happens after privileges are dropped, so
5607 that checking the passwd entry still works.
5608 - minor touch up of clear() hashtable function.
5609 - VERB_DETAIL prints out what chdir, username, chroot is being done.
5610 - when id numbers run out, caches are cleared, as in design notes.
5611 Tested with a mock setup with very few bits in id, it worked.
5612 - harden-dnssec-stripped: yes is now default. It insists on dnssec
5613 data for trust anchors. Included tests for the feature.
5615 31 October 2007: Wouter
5616 - cache-max-ttl config option.
5617 - building outside sourcedir works again.
5618 - defaults more secure:
5620 chroot: "/etc/unbound"
5621 The operator can override them to be less secure ("") if necessary.
5622 - fix horrible oversight in sorting rrset references in a message,
5623 sort per reference key pointer, not on referencepointer itself.
5624 - pidfile: "/etc/unbound/unbound.pid" is now the default.
5625 - tests changed to reflect the updated default.
5626 - created hashtable clear() function that respects locks.
5628 30 October 2007: Wouter
5629 - fixup assertion failure that relied on compressed names to be
5630 smaller than uncompressed names. A packet from comrite.com was seen
5631 to be compressed to a larger size. Added it as unit test.
5632 - quieter logging at low verbosity level for common tcp messages.
5633 - no greedy TTL update.
5635 23 October 2007: Wouter
5636 - fixup (grand-)parent problem for dnssec-lameness detection.
5637 - fixup tests to do additional section processing for lame replies,
5638 since the detection needs that.
5639 - no longer trust in query section in reply during dnssec lame detect.
5640 - dnssec lameness does not make the server never ever queried, but
5641 non-preferred. If no other servers exist or answer, the dnssec lame
5642 server is used; the fastest dnssec lame server is chosen.
5643 - added test then when trust anchor cannot be primed (nodata), the
5644 insecure mode from unbound works.
5645 - Fixup max queries per thread, any more are dropped.
5647 22 October 2007: Wouter
5648 - added donotquerylocalhost config option. Can be turned off for
5650 - ISO C compat changes.
5651 - detect RA-no-AA lameness, as LAME.
5652 - DNSSEC-lameness detection, as LAME.
5653 See notes in requirements.txt for choices made.
5654 - tests for lameness detection.
5655 - added all to make test target; need unbound for fwd tests.
5656 - testbound does not pollute /etc/unbound.
5658 19 October 2007: Wouter
5659 - added configure (and its files) to svn, so that the trunk is easier
5660 to use. ./configure, config.guess, config.sub, ltmain.sh,
5662 - added yacc/lex generated files, util/configlexer.c,
5663 util/configparser.c util/configparser.h, to svn.
5664 - without lex no attempt to use it.
5665 - unsecure response validation collated into one block.
5666 - remove warning about const cast of cfgfile name.
5667 - outgoing-interfaces can be different from service interfaces.
5668 - ldns-src configure is done during unbound configure and
5669 ldns-src make is done during unbound make, and so inherits the
5670 make arguments from the unbound make invocation.
5671 - nicer error when libevent problem causes instant exit on signal.
5672 - read root hints from a root hint file (like BIND does).
5674 18 October 2007: Wouter
5675 - addresses are logged with errors.
5676 - fixup testcode fake event to remove pending before callback
5677 since the callback may create new pending items.
5678 - tests updated because retries are now in iterator module.
5679 - ldns-testpkts code is checked for differences between unbound
5680 and ldns by makedist.sh.
5681 - ldns trunk from today added in svn repo for fallback in case
5682 no ldns is installed on the system.
5683 make download_ldns refreshes the tarball with ldns svn trunk.
5684 - ldns-src.tar.gz is used if no ldns is found on the system, and
5685 statically linked into unbound.
5686 - start of regional allocator code.
5687 - regional uses less memory and variables, simplified code.
5688 - remove of region-allocator.
5689 - alloc cache keeps a cache of recently released regional blocks,
5691 - make unit test cleanly free memory.
5693 17 October 2007: Wouter
5694 - fixup another cycle detect and ns-addr timeout resolution bug.
5695 This time by refusing delegations from the cache without addresses
5696 when resolving a mandatory-glue nameserver-address for that zone.
5697 We're going to have to ask a TLD server anyway; might as well be
5698 the TLD server for this name. And this resolves a lot of cases where
5699 the other nameserver names lead to cycles or are not available.
5700 - changed random generator from random(3) clone to arc4random wrapped
5701 for thread safety. The random generator is initialised with
5702 entropy from the system.
5703 - fix crash where failure to prime DNSKEY tried to print null pointer
5705 - removed some debug prints, only verb_algo (4) enables them.
5706 - fixup test; new random generator took new paths; such as one
5707 where no scripted answer was available.
5708 - mark insecure RRs as insecure.
5709 - fixup removal of nonsecure items from the additional.
5710 - reduced timeout values to more realistic, 376 msec (262 msec has
5711 90% of roundtrip times, 512 msec has 99% of roundtrip times.)
5712 - server selection failover to next server after timeout (376 msec).
5714 16 October 2007: Wouter
5715 - no malloc in log_hex.
5716 - assertions around system calls.
5717 - protect against gethostname without ending zero.
5718 - ntop output is null terminated by unbound.
5719 - pidfile content null termination
5720 - various snprintf use sizeof(stringbuf) instead of fixed constant.
5721 - changed loopdetect % 8 with & 0x7 since % can become negative for
5722 weird negative input and particular interpretation of integer math.
5723 - dname_pkt_copy checks length of result, to protect result buffers.
5724 prints an error, this should not happen. Bad strings should have
5725 been rejected earlier in the program.
5726 - remove a size_t underflow from msgreply size func.
5728 15 October 2007: Wouter
5730 - fix IP6 TCP, wrong definition check. With test package.
5731 - fixup the fact that the query section was not compressed to,
5732 the code was there but was called by value instead of by reference.
5733 And test for the case, uses xxd and nc.
5734 - more portable ip6 check for sockaddr types.
5736 8 October 2007: Wouter
5737 - --disable-rpath option in configure for 64bit systems with
5738 several dynamic lib dirs.
5740 7 October 2007: Wouter
5741 - fixup tests for no AD bit in non-DO queries.
5742 - test that makes sure AD bit is not set on non-DO query.
5744 6 October 2007: Wouter
5745 - removed logfile open early. It did not have the proper permissions;
5746 it was opened as root instead of the user. And we cannot change user
5747 id yet, since chroot and bind ports need to be done.
5748 - callback checks for event callbacks done from mini_event. Because
5749 of deletions cannot do this from netevent. This means when using
5750 libevent the protection does not work on event-callbacks.
5751 - fixup too small reply (did not zero counts).
5752 - fixup reply no longer AD bit when query without DO bit.
5754 5 October 2007: Wouter
5755 - function pointer whitelist.
5757 4 October 2007: Wouter
5758 - overwrite sensitive random seed value after use.
5759 - switch to logfile very soon if not -d (console attached).
5760 - error messages do not reveal the trustanchor contents.
5761 - start work on function pointer whitelists.
5763 3 October 2007: Wouter
5764 - fix for multiple empty nonterminals, after multiple DSes in the
5766 - mesh checks if modules are looping, and stops them.
5767 - refetch with CNAMEd nameserver address regression test added.
5768 - fixup line count bug in testcode, so testbound prints correct line
5769 number with parse errors.
5770 - unit test for multiple ENT case.
5771 - fix for cname out of validated unsec zone.
5772 - fixup nasty id=0 reuse. Also added assertions to detect its
5773 return (the assertion catches in the existing test cases).
5775 1 October 2007: Wouter
5776 - skip F77, CXX, objC tests in configure step.
5777 - fixup crash in refetch glue after a CNAME.
5778 and protection against similar failures (with error print).
5780 28 September 2007: Wouter
5781 - test case for unbound-checkconf, fixed so it also checks the
5782 interface: statements.
5784 26 September 2007: Wouter
5785 - SIGHUP will reopen the log file.
5786 - Option to log to syslog.
5787 - please lint, fixup tests (that went to syslog on open, oops).
5788 - config check program.
5790 25 September 2007: Wouter
5791 - tests for NSEC3. Fixup bitmap checks for NSEC3.
5792 - positive ANY response needs to check if wildcard expansion, and
5793 check that original data did not exist.
5794 - tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
5795 delegation, for abuse of child zone apex nsec3.
5796 - create 0.5 release tag.
5798 24 September 2007: Wouter
5799 - do not make test programs by default.
5800 - But 'make test' will perform all of the tests.
5801 - Advertise builtin select libevent alternative when no libevent
5803 - signit can generate NSEC3 hashes, for generating tests.
5804 - multiple nsec3 parameters in message test.
5805 - too high nsec3 iterations becomes insecure test.
5807 21 September 2007: Wouter
5808 - fixup empty_DS_name allocated in wrong region (port DEC Alpha).
5809 - fixup testcode lock safety (port FreeBSD).
5810 - removes subscript has type char warnings (port Solaris 9).
5811 - fixup of field with format type to int (port MacOS/X intel).
5812 - added test for infinite loop case in nonRD answer validation.
5813 It was a more general problem, but hard to reproduce. When an
5814 unsigned rrset is being validated and the key fetched, the DS
5815 sequence is followed, but if the final name has no DS, then no
5816 proof is possible - the signature has been stripped off.
5818 20 September 2007: Wouter
5819 - fixup and test for NSEC wildcard with empty nonterminals.
5820 - makedist.sh fixup for svn info.
5821 - acl features request in plan.
5822 - improved DS empty nonterminal handling.
5823 - compat with ANS nxdomain for empty nonterminals. Attempts the nodata
5824 proof anyway, which succeeds in ANS failure case.
5825 - striplab protection in case it becomes -1.
5826 - plans for static and blacklist config.
5828 19 September 2007: Wouter
5829 - comments about non-packed usage.
5830 - plan for overload support in 0.6.
5831 - added testbound tests for a failed resolution from the logs
5832 and for failed prime when missing glue.
5833 - fixup so useless delegation points are not returned from the
5834 cache. Also the safety belt is used if priming fails to complete.
5835 - fixup NSEC rdata not to be lowercased, bind compat.
5837 18 September 2007: Wouter
5838 - wildcard nsec3 testcases, and fixup to get correct wildcard name.
5839 - validator prints subtype classification for debug.
5841 17 September 2007: Wouter
5842 - NSEC3 hash cache unit test.
5843 - validator nsec3 nameerror test.
5845 14 September 2007: Wouter
5846 - nsec3 nodata proof, nods proof, wildcard proof.
5847 - nsec3 support for cname chain ending in noerror or nodata.
5848 - validator calls nsec3 proof routines if no NSECs prove anything.
5849 - fixup iterator bug where it stored the answer to a cname under
5850 the wrong qname into the cache. When prepending the cnames, the
5851 qname has to be reset to the original qname.
5853 13 September 2007: Wouter
5854 - nsec3 find matching and covering, ce proof, prove namerror msg.
5856 12 September 2007: Wouter
5857 - fixup of manual page warnings, like for NSD bugreport.
5858 - nsec3 work, config, max iterations, filter, and hash cache.
5860 6 September 2007: Wouter
5861 - fixup to find libevent on mac port install.
5862 - fixup size_t vs unsigned portability in validator/sigcrypt.
5863 - please compiler on different platforms, for unreachable code.
5865 - pthread_rwlock type is optional, in case of old pthread libs.
5867 5 September 2007: Wouter
5868 - cname, name error validator tests.
5869 - logging of qtype ANY works.
5870 - ANY type answers get RRSIG in answer section of replies (but not
5871 in other sections, unless DO bit is on).
5872 - testbound can replay a TCP query (set MATCH TCP in the QUERY).
5873 - DS and noDS referral validation test.
5874 - if you configure many trust anchors, parent trust anchors can
5875 securely deny existence of child trust anchors, if validated.
5876 - not all *.name NSECs are present because a wildcard was matched,
5877 and *.name NSECs can prove nodata for empty nonterminals.
5878 Also, for wildcard name NSECs, check they are not from the parent
5879 zone (for wildcarded zone cuts), and check absence of CNAME bit,
5881 - configure option for memory allocation debugging.
5882 - port configure option for memory allocation to solaris10.
5884 4 September 2007: Wouter
5885 - fixup of Leakage warning when serviced queries processed multiple
5886 callbacks for the same query from the same server.
5887 - testbound removes config file from /tmp on failed exit.
5888 - fixup for referral cleanup of the additional section.
5889 - tests for cname, referral validation.
5890 - neater testbound tpkg output.
5891 - DNAMEs no longer match their apex when synthesized from the cache.
5892 - find correct signer name for DNAME responses.
5893 - wildcarded DNAME test and fixup code to detect.
5894 - prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
5895 So that wildcarded CNAMEs get their NSEC with them to the answer.
5896 - test for a CNAME to a DNAME to a CNAME to an answer, all from
5897 different domains, for key fetching and signature checking of
5900 3 September 2007: Wouter
5901 - Fixed error in iterator that would cause assertion failure in
5902 validator. CNAME to a NXDOMAIN response was collated into a response
5903 with both a CNAME and the NXDOMAIN rcode. Added a test that the
5904 rcode is changed to NOERROR (because of the CNAME).
5905 - timeout on tcp does not lead to spurious leakage detect.
5906 - account memory for name of lame zones, so that memory leakages does
5907 not show lame cache growth as a leakage growth.
5908 - config setting for lameness cache expressed in bytes, instead of
5910 - tool too summarize allocations per code line.
5912 31 August 2007: Wouter
5913 - can read bind trusted-keys { ... }; files, in a compatibility mode.
5914 - iterator should not detach target queries that it still could need.
5915 the protection against multiple outstanding queries is moved to a
5916 current_query num check.
5917 - validator nodata, positive, referral tests.
5918 - dname print can print '*' wildcard.
5920 30 August 2007: Wouter
5921 - fixup override date config option.
5922 - config options to control memory usage.
5923 - caught bad free of un-alloced data in worker_send error case.
5924 - memory accounting for key cache (trust anchors and temporary cache).
5925 - memory accounting fixup for outside network tcp pending waits.
5926 - memory accounting fixup for outside network tcp callbacks.
5927 - memory accounting for iterator fixed storage.
5928 - key cache size and slabs config options.
5929 - lib crypto cleanups at exit.
5931 29 August 2007: Wouter
5932 - test tool to sign rrsets for testing validator with.
5933 - added RSA and DSA test keys, public and private pairs, 512 bits.
5934 - default configuration is with validation enabled.
5935 Only a trust-anchor needs to be configured for DNSSEC to work.
5936 - do not convert to DER for DSA signature verification.
5937 - validator replay test file, for a DS to DNSKEY DSA key prime and
5940 28 August 2007: Wouter
5941 - removed double use for udp buffers, that could fail,
5942 instead performs a malloc to do the backup.
5943 - validator validates referral messages, by validating all the rrsets
5944 and stores the rrsets in the cache. Further referral (nonRD queries)
5945 replies are made from the rrset cache directly. Unless unchecked
5946 rrsets are encountered, there are then validated.
5947 - enforce that signing is done by a parent domain (or same domain).
5948 - adjust TTL downwards if rrset TTL bigger than signature allows.
5949 - permissive mode feature, sets AD bit for secure, but bogus does
5950 not give servfail (bogus is changed into indeterminate).
5951 - optimization of rrset verification. rr canonical sorting is reused,
5952 for the same rrset. canonical rrset image in buffer is reused for
5954 - if the rrset is too big (64k exactly + large owner name) the
5955 canonicalization routine will fail if it does not fit in buffer.
5956 - faster verification for large sigsets.
5957 - verb_detail mode reports validation failures, but not the entire
5958 algorithm for validation. Key prime failures are reported as
5961 27 August 2007: Wouter
5962 - do not garble the edns if a cache answer fails.
5963 - answer norecursive from cache if possible.
5964 - honor clean_additional setting when returning secure non-recursive
5966 - do not store referral in msg cache for nonRD queries.
5967 - store verification status in the rrset cache to speed up future
5969 - mark rrsets indeterminate and insecure if they are found to be so.
5970 and store this in the cache.
5972 24 August 2007: Wouter
5973 - message is bogus if unsecure authority rrsets are present.
5974 - val-clean-additional option, so you can turn it off.
5975 - move rrset verification out of the specific proof types into one
5976 routine. This makes the proof routines prettier.
5977 - fixup cname handling in validator, cname-to-positive and cname-to-
5979 - Do not synthesize DNSKEY and DS responses from the rrset cache if
5980 the rrset is from the additional section. Signatures may have
5981 fallen off the packet, and cause validation failure.
5982 - more verbose signature date errors (with the date attached).
5983 - increased default infrastructure cache size. It is important for
5984 performance, and 1000 entries are only 212k (or a 400 k total cache
5985 size). To 10000 entries (for 2M entries, 4M cache size).
5987 23 August 2007: Wouter
5988 - CNAME handling - move needs_validation to before val_new().
5989 val_new() setups the chase-reply to be an edited copy of the msg.
5990 new classification, and find signer can find for it.
5991 removal of unsigned crap from additional, and query restart for
5993 - refuse to follow wildcarded DNAMEs when validating.
5994 But you can query for qtype ANY, or qtype DNAME and validate that.
5996 22 August 2007: Wouter
5998 - review - use val_error().
6000 21 August 2007: Wouter
6001 - ANY response validation.
6002 - store security status in cache.
6003 - check cache security status and either send the query to be
6004 validated, return the query to client, or send servfail to client.
6005 Sets AD bit on validated replies.
6006 - do not examine security status on an error reply in mesh_done.
6007 - construct DS, DNSKEY messages from rrset cache.
6008 - manual page entry for override-date.
6010 20 August 2007: Wouter
6011 - validate and positive validation, positive wildcard NSEC validation.
6012 - nodata validation, nxdomain validation.
6014 18 August 2007: Wouter
6015 - process DNSKEY response in FINDKEY state.
6017 17 August 2007: Wouter
6018 - work on DS2KE routine.
6019 - val_nsec.c for validator NSEC proofs.
6020 - unit test for NSEC bitmap reading.
6021 - dname iswild and canonical_compare with unit tests.
6023 16 August 2007: Wouter
6025 - latest release libevent 1.3c and 1.3d have threading fixed.
6026 - key entry fixup data pointer and ttl absolute.
6027 - This makes a key-prime succeed in validator, with DS or DNSKEY as
6029 - fixup canonical compare byfield routine, fix bug and also neater.
6030 - fixed iterator response type classification for queries of type
6032 dig ANY gives sometimes NS rrset in AN and NS section, and parser
6033 removes the NS section duplicate. dig NS gives sometimes the NS
6034 in the answer section, as referral.
6035 - validator FINDKEY state.
6037 15 August 2007: Wouter

6048 - --enable-lock-checks can be used to enable lock checking.
6049 - protect undefs in config.h from autoheaders ministrations.
6050 - print all received udp packets. log hex will print on multiple
6052 - fixed error in parser with backwards rrsig references.
6053 - mark cycle targets for iterator did not have CD flag so failed
6056 13 August 2007: Wouter
6057 - fixup makefile, if lexer is missing give nice error and do not
6058 mess up the dependencies.
6059 - canonical compare routine updated.
6060 - canonical hinfo compare.
6061 - printout list of the queries that the mesh is working on.
6063 10 August 2007: Wouter
6064 - malloc and free overrides that track total allocation and frees.
6065 for memory debugging.
6066 - work on canonical sort.

6084 - security status is copied when rdata is equal for rrsets.
6085 - rrset id is updated to invalidate all the message cache entries
6086 that refer to NSEC, NSEC3, DNAME rrsets that have changed.
6088 - val_sigcrypt file for validator signature checks.
6090 6 August 2007: Wouter
6091 - key cache for validator.
6092 - moved isroot and dellabel to own dname routines, with unit test.
6094 3 August 2007: Wouter
6096 - scrubber check section of lame NS set.
6097 - trust anchors can be in config file or read from zone file,
6098 DS and DNSKEY entries.
6099 - unit test trust anchor storage.
6100 - trust anchors converted to packed rrsets.
6101 - key entry definition.
6103 2 August 2007: Wouter
6104 - configure change for latest libevent trunk version (needs -lrt).
6105 - query_done and walk_supers are moved out of module interface.
6106 - fixup delegation point duplicates.
6107 - fixup iterator scrubber; lame NS set is let through the scrubber
6108 so that the classification is lame.
6109 - validator module exists, and does nothing but pass through,
6110 with calling of next module and return.
6113 1 August 2007: Wouter
6114 - set version to 0.5
6115 - module work for module to module interconnections.
6116 - config of modules.
6117 - detect cycle takes flags.
6119 31 July 2007: Wouter
6123 30 July 2007: Wouter
6124 - changed random state init, so that sequential process IDs are not
6125 cancelled out by sequential thread-ids in the random number seed.
6126 - the fwd_three test, which sends three queries to unbound, and
6127 unbound is kept waiting by ldns-testns for 3 seconds, failed
6128 because the retry timeout for default by unbound is 3 seconds too,
6129 it would hit that timeout and fail the test. Changed so that unbound
6130 is kept waiting for 2 seconds instead.
6132 27 July 2007: Wouter
6133 - removed useless -C debug option. It did not work.
6134 - text edit of documentation.
6135 - added doc/CREDITS file, referred to by the manpages.
6138 26 July 2007: Wouter
6139 - cycle detection, for query state dependencies. Will attempt to
6140 circumvent the cycle, but if no other targets available fails.
6141 - unit test for AXFR, IXFR response.
6142 - test for cycle detection.
6144 25 July 2007: Wouter
6145 - testbound read ADDRESS and check it.
6146 - test for version.bind and friends.
6147 - test for iterator chaining through several referrals.
6148 - test and fixup for refetch for glue. Refetch fails if glue
6149 is still not provided.
6151 24 July 2007: Wouter
6152 - Example section in config manual.
6153 - Addr stored for range and moment in replay.
6155 20 July 2007: Wouter
6156 - Check CNAME chain before returning cache entry with CNAMEs.
6157 - Option harden-glue, default is on. It will discard out of zone
6158 data. If disabled, performance is faster, but spoofing attempts
6159 become a possibility. Note that still normalize scrubbing is done,
6160 and that the potentially spoofed data is used for infrastructure
6161 and not returned to the client.
6162 - if glue times out, refetch by asking parent of delegation again.
6163 Much like asking for DS at the parent side.
6164 - TODO items from forgery-resilience draft.
6165 and on memory handling improvements.
6166 - renamed module_event_timeout to module_event_noreply.
6167 - memory reporting code; reports on memory usage after handling
6168 a network packet (not on cache replies).
6170 19 July 2007: Wouter
6171 - shuffle NS selection when getting nameserver target addresses.
6172 - fixup of deadlock warnings, yield cpu in checklock code so that
6173 freebsd scheduler selects correct process to run.
6174 - added identity and version config options and replies.
6175 - store cname messages complete answers.
6177 18 July 2007: Wouter
6178 - do not query addresses, 127.0.0.1, and ::1 by default.
6180 17 July 2007: Wouter
6181 - forward zone options in config file.
6182 - forward per zone in iterator. takes precedence over stubs.
6183 - fixup commithooks.
6184 - removed forward-to and forward-to-port features, subsumed by
6186 - fix parser to handle absent server: clause.
6187 - change untrusted rrset test to account for scrubber that is now
6188 applied during the test (which removes the poison, by the way).
6189 - feature, addresses can be specified with @portnumber, like nsd.conf.
6190 - test config files changed over to new forwarder syntax.
6192 27 June 2007: Wouter
6193 - delete of mesh does a postorder traverse of the tree.
6194 - found and fixed a memory leak. For TTL=0 messages, that would
6195 not be cached, instead the msg-replyinfo structure was leaked.
6196 - changed server selection so it will filter out hosts that are
6197 unresponsive. This is defined as a host with the maximum rto value.
6198 This means that unbound tried the host for retries up to 120 secs.
6199 The rto value will time out after host-ttl seconds from the cache.
6200 This keeps such unresolvable queries from taking up resources.
6201 - utility for keeping histogram.
6203 26 June 2007: Wouter
6204 - mesh is called by worker, and iterator uses it.
6205 This removes the hierarchical code.
6206 QueryTargets state and Finished state are merged for iterator.
6207 - forwarder mode no longer sets AA bit on first reply.
6208 - rcode in walk_supers is not needed.
6210 25 June 2007: Wouter
6212 - error encode routine for ease.
6214 22 June 2007: Wouter
6215 - removed unused _node iterator value from rbtree_t. Takes up space.
6216 - iterator can handle querytargets state without a delegation point
6217 set, so that a priming(stub) subquery error can be handled.
6218 - iterator stores if it is priming or not.
6219 - log_query_info() neater logging.
6220 - changed iterator so that it does not alter module_qstate.qinfo
6221 but keeps a chase query info. Also query_flags are not altered,
6222 the iterator uses chase_flags.
6223 - fixup crash in case no ports for the family exist.
6225 21 June 2007: Wouter
6226 - Fixup secondary buffer in case of error callback.
6227 - cleanup slumber list of runnable states.
6228 - module_subreq_depth fails to work in slumber list.
6229 - fixup query release for cached results to sub targets.
6230 - neater error for tcp connection failure, shows addr in verbose.
6231 - rbtree_init so that it can be used with preallocated memory.
6233 20 June 2007: Wouter
6234 - new -C option to enable coredumps after forking away.
6236 - fixup CNAME generation by scrubber, and memory allocation of it.
6237 - fixup deletion of serviced queries when all callbacks delete too.
6238 - set num target queries to 0 when you move them to slumber list.
6239 - typo in check caused subquery errors to be ignored, fixed.
6240 - make lint happy about rlim_t.
6241 - freeup of modules after freeup of module-states.
6242 - duplicate replies work, this uses secondary udp buffer in outnet.
6244 19 June 2007: Wouter
6245 - nicer layout in stats.c, review 0.3 change.
6246 - spelling improvement, review 0.3 change.
6247 - uncapped timeout for server selection, so that very fast or slow
6248 servers will stand out from the rest.
6249 - target-fetch-policy: "3 2 1 0 0" config setting.
6250 - fixup queries answered without RD bit (for root prime results).
6251 - refuse AXFR and IXFR requests.
6252 - fixup RD flag in error reply from iterator. fixup RA flag from
6254 - fixup encoding of very short edns buffer sizes, now sets TC bit.
6255 - config options harden-short-bufsize and harden-large-queries.
6257 18 June 2007: Wouter
6258 - same, move subqueries to slumber list when first has resolved.
6259 - fixup last fix for duplicate callbacks.
6260 - another offbyone in targetcounter. Also in Java prototype by the way.
6262 15 June 2007: Wouter
6263 - if a query asks to be notified of the same serviced query result
6264 multiple times, this will succeed. Only one callback will happen;
6265 multiple outbound-list entries result (but the double cleanup of it
6267 - when iterator moves on due to CNAME or referral, it will remove
6268 the subqueries (for other targets). These are put on the slumber
6270 - state module wait subq is OK with no new subqs, an old one may have
6271 stopped, with an error, and it is still waiting for other ones.
6272 - if a query loops, halt entire query (easy way to clean up properly).
6274 14 June 2007: Wouter
6275 - num query targets was > 0 , not >= 0 compared, so that fetch
6276 policy of 0 did nothing.
6278 13 June 2007: Wouter
6279 - debug option: configure --enable-static-exe for compile where
6280 ldns and libevent are linked statically. Default is off.
6281 - make install and make uninstall. Works with static-exe and without.
6282 installation of unbound binary and manual pages.
6283 - alignment problem fix on solaris 64.
6284 - fixup address in case of TCP error.
6286 12 June 2007: Wouter
6287 - num target queries was set to 0 at a bad time. Default it to 0 and
6288 increase as target queries are done.
6289 - synthesize CNAME and DNAME responses from the cache.
6290 - Updated doxygen config for doxygen 1.5.
6291 - aclocal newer version.
6292 - doxygen 1.5 fixes for comments (for the strict check on docs).
6294 11 June 2007: Wouter
6295 - replies on TCP queries have the address field set in replyinfo,
6296 for serviced queries, because the initiator does not know that
6297 a TCP fallback has occured.
6298 - omit DNSSEC types from nonDO replies, except if qtype is ANY or
6299 if qtype directly queries for the type (and then only show that
6300 'unknown type' in the answer section).
6301 - fixed message parsing where rrsigs on their own would be put
6302 in the signature list over the rrsig type.
6305 - fixup error in double linked list insertion for subqueries and
6306 for outbound list of serviced queries for iterator module.
6307 - nicer printout of outgoing port selection.
6308 - fixup cname target readout.
6309 - nicer debug output.
6310 - fixup rrset counts when prepending CNAMEs to the answer.
6311 - fixup rrset TTL for prepended CNAMEs.
6312 - process better check for looping modules, and which submodule to
6314 - subreq insertion code fixup for slumber list.
6315 - VERB_DETAIL, verbosity: 2 level gives short but readable output.
6316 VERB_ALGO, verbosity: 3 gives extensive output.
6317 - fixup RA bit in cached replies.
6318 - fixup CNAME responses from the cache no longer partial response.
6319 - error in network send handled without leakage.
6320 - enable ip6 from config, and try ip6 addresses if available,
6321 if ip6 is not connected, skips to next server.
6324 - iterator state finished.
6325 - subrequests without parent store in cache and stop.
6326 - worker slumber list for ongoing promiscuous queries.

6330 - debug routine to print dns_msg as handled by iterator.
6331 - memleak in config file stubs fixup.
6332 - more small bugs, in scrubber, query compare no ID for lookup,
6333 in dname validation for NS targets.
6334 - sets entry.key for new special allocs.
6335 - lognametypeclass can display unknown types and classes.
6338 - random selection of equally preferred nameserver targets.
6339 - reply info copy routine. Reuses existing code.
6340 - cache lameness in response handling.
6341 - do not touch qstate after worker_process_query because it may have
6342 been deleted by that routine.
6343 - Prime response state.
6344 - Process target response state.
6345 - some memcmp changed to dname_compare for case preservation.
6348 - normalize incoming messages. Like unbound-java, with CNAME chain
6349 checked, DNAME checked, CNAME's synthesized, glue checked.
6350 - sanitize incoming messages.
6351 - split msgreply encode functions into own file msgencode.c.
6352 - msg_parse to queryinfo/replyinfo conversion more versatile.
6353 - process_response, classify response, delegpt_from_message.
6356 - querytargets state.
6357 - dname_subdomain_c() routine.
6358 - server selection, based on RTT. ip6 is filtered out if not available,
6359 and lameness is checked too.
6360 - delegation point copy routine.
6363 - removed FLAG_CD from message and rrset caches. This was useful for
6364 an agnostic forwarder, but not for a sophisticated (trust value per
6365 rrset enabled) cache.
6366 - iterator response typing.
6367 - iterator cname handle.
6368 - iterator prime start.
6370 - processInitRequest and processInitRequest2.
6371 - cache synthesizes referral messages, with DS and NSEC.
6372 - processInitRequest3.
6373 - if a request creates multiple subrequests these are all activated.
6376 - routines to lock and unlock array of rrsets moved to cache/rrset.
6377 - lookup message from msg cache (and copy to region).

6380 - 'qnamesize' changed to 'qname_len' for similar naming scheme.
6383 - Acknowledge use of unbound-java code in iterator. Nicer readme.
6384 - services/cache/dns.c DNS Cache. Hybrid cache uses msgcache and
6385 rrset cache from module environment.
6386 - packed rrset key has type and class as easily accessible struct
6387 members. They are still kept in network format for fast msg encode.
6388 - dns cache find_delegation routine.
6389 - iterator main functions setup.
6390 - dns cache lookup setup.
6393 - small changes to prepare for subqueries.
6394 - iterator forwarder feature separated out.
6395 - iterator hints stub code, config file stub code, so that first
6396 testing can proceed locally.
6397 - replay tests now have config option to enable forwarding mode.
6400 - outside network does precise timers for roundtrip estimates for rtt
6401 and for setting timeout for UDP. Pending_udp takes milliseconds.
6402 - cleaner iterator sockaddr conversion of forwarder address.
6403 - iterator/iter_utils and iter_delegpt setup.
6407 - outbound query list for modules and support to callback with the
6408 outbound entry to the module.

6412 - fixes for no-locking compile.
6413 - mini_event timer precision and fix for change in timeouts during
6414 timeout callback. Fix for fwd_three tests, performed nonexit query.
6417 - small comment on hash table locking.
6418 - outside network serviced queries, contain edns and tcp fallback,
6419 and udp retries and rtt timing.

6467 - EDNS read from query, used to make reply smaller.
6468 - advertised edns value constants.
6469 - EDNS BADVERS response, if asked for too high edns version.
6470 - EDNS extended error responses once the EDNS record from the query
6471 has successfully been parsed.
6474 - msgreply sizefunc is more accurate.
6475 - config settings for rrset cache size and slabs.
6476 - hashtable insert takes argument so that a thread can use its own
6477 alloc cache to store released keys.
6478 - alloc cache special_release() locks if necessary.
6479 - rrset trustworthiness type added.
6480 - thread keeps a scratchpad region for handling messages.

6491 - uses new msgreply format in cache.
6494 - dname unit tests in own file and spread out neatly in functions.
6495 - more dname unit tests.
6496 - message encoding creates truncated TC flagged messages if they do
6497 not fit, and will leave out (whole)rrsets from additional if needed.
6500 - decompress query section, extremely lenient acceptance.
6501 But only for answers from other servers, not for plain queries.
6502 - compression and decompression test cases.
6504 - example.conf interface: line is changed from 127.0.0.1 which leads
6505 to problems if used (restricting communication to the localhost),
6506 to a documentation and test address.
6508 27 April 2007: Wouter

6579 start of sectionparse.
6581 10 April 2007: Wouter
6582 - Improved alignment of reply_info packet, nice for 32 and 64 bit.

6597 - layout of memory for rrsets.
6599 3 April 2007: Wouter
6600 - detect sign of msghdr.msg_iovlen so that the cast to that type
6601 in netevent (which is there to please lint) can be correct.
6602 The type on several OSes ranges from int, int32, uint32, size_t.
6603 Detects unsigned or signed using math trick.

6616 - review changes msgreply.c, memleak on error condition. AA flag
6617 clear on cached reply. Lowercase queries on hashing.
6618 unit test on lowercasing. Test AA bit not set on cached reply.
6619 Note that no TTLs are managed.
6621 29 March 2007: Wouter
6622 - writev or sendmsg used when answering from cache.
6623 This avoids a copy of the data.
6624 - do not do useless byteswap on query id. Store reply flags in uint16
6625 for easier access (and no repeated byteswapping).
6627 - configure detects and config.h includes sys/uio.h for writev decl.
6629 28 March 2007: Wouter
6630 - new config option: num-queries-per-thread.
6631 - added tpkg test for answering three queries at the same time
6632 using one thread (from the query service list).
6634 27 March 2007: Wouter
6635 - added test for cache and not cached answers, in testbound replays.
6636 - testbound can give config file and commandline options from the
6637 replay file to unbound.
6638 - created test that checks if items drop out of the cache.
6639 - added word 'partitioned hash table' to documentation on slab hash.
6640 A slab hash is a partitioned hash table.

6650 - covered up memory leak of the entry locks.
6651 - answers from the cache correctly. Copies flags correctly.
6652 - sanity check for incoming query replies.
6653 - slabbed hash table. Much nicer contention, need dual cpu to see.
6655 22 March 2007: Wouter
6656 - AIX configure check.
6657 - lock-verify can handle references to locks that are created
6658 in files it has not yet read in.
6659 - threaded hash table test.
6660 - unit test runs lock-verify afterwards and checks result.
6661 - need writelock to update data on hash_insert.
6662 - message cache code, msgreply code.
6664 21 March 2007: Wouter
6665 - unit test of hash table, fixup locking problem in table_grow().
6666 - fixup accounting of sizes for removing items from hashtable.

6682 12 March 2007: Wouter
6683 - configure.ac moved to 0.2.
6684 - query_info and replymsg util/data structure.
6686 9 March 2007: Wouter
6687 - added rwlock writelock checking.
6688 So it will keep track of the writelock, and readlocks are enforced
6689 to not change protected memory areas.
6690 - log_hex function to dump hex strings to the logfile.
6691 - checklocks zeroes its destroyed lock after checking memory areas.
6692 - unit test for alloc.

6701 checking for data race and deadlock, and basic performance
6702 contention measurement.
6704 6 March 2007: Wouter
6705 - Testbed works with threading (different machines, different options).
6706 - alloc work, does the special type.
6708 2 March 2007: Wouter
6709 - do not compile fork funcs unless needed. Otherwise will give
6710 type errors as their typedefs have not been enabled.
6711 - log shows thread numbers much more nicely (and portably).
6712 - even on systems with nonthreadsafe libevent signal handling,
6713 unbound will exit if given a signal.
6714 Reloads will not work, and exit is not graceful.
6715 - start of alloc framework layout.
6717 1 March 2007: Wouter
6718 - Signals, libevent and threads work well, with libevent patch and
6719 changes to code (close after event_del).

6722 27 February 2007: Wouter
6723 - ub_thread_join portable definition.
6724 - forking is used if no threading is available.
6725 Tested, it works, since pipes work across processes as well.
6726 Thread_join is replaced with waitpid.
6727 - During reloads the daemon will temporarily handle signals,
6728 so that they do not result in problems.
6729 - Also randomize the outgoing port range for tests.
6730 - If query list is full, will stop selecting listening ports for read.
6731 This makes all threads service incoming requests, instead of one.
6732 No memory is leaking during reloads, service of queries, etc.
6733 - test that uses ldns-testns -f to test threading. Have to answer
6734 three queries at the same time.
6735 - with verbose=0 operates quietly.
6737 26 February 2007: Wouter
6738 - ub_random code used to select ID and port.
6739 - log code prints thread id.
6740 - unbound can thread itself, with reload(HUP) and quit working
6742 - don't open pipes for #0, doesn't need it.
6743 - listens to SIGTERM, SIGQUIT, SIGINT (all quit) and SIGHUP (reload).
6745 23 February 2007: Wouter
6746 - Can do reloads on sigHUP. Everything is stopped, and freed,
6747 except the listening ports. Then the config file is reread.
6748 And everything is started again (and listening ports if needed).
6749 - Ports for queries are shared.
6750 - config file added interface:, chroot: and username:.
6751 - config file: directory, logfile, pidfile. And they work too.
6752 - will daemonize by default now. Use -d to stay in the foreground.
6753 - got BSD random[256 state] code, made it threadsafe. util/random.
6755 22 February 2007: Wouter

6776 16 February 2007: Wouter
6777 - Updated testbed script, works better by using make on remote end.
6778 - removed check decls, we can compile without them.
6779 - makefile supports LIBOBJ replacements.
6780 - docs checks ignore compat code.
6781 - added util/mini-event.c and .h, a select based alternative used with
6782 ./configure --with-libevent=no
6783 It is limited to 1024 file descriptors, and has less features.
6784 - will not create ip6 sockets if ip6 not on the machine.
6786 15 February 2007: Wouter
6787 - port to FreeBSD 4.11 Dec Alpha. Also works on Solaris 10 sparc64,
6788 Solaris 9, FreeBSD 6, Linux i386 and OSX powerpc.
6789 - malloc rndstate, so that it is aligned for access.
6790 - fixed rbtree cleanup with postorder traverse.
6791 - fixed pending messages are deleted when handled.
6792 - You can control verbosity; default is not verbose, every -v
6793 adds more verbosity.

6796 - Included configure.ac changes from ldns.
6797 - detect (some) headers before the standards check.
6798 - do not use isblank to test c99, since its not available on solaris9.
6799 - review of testcode.
6800 * entries in a RANGE are no longer reversed.
6801 * print name of file with replay entry parse errors.

6822 - testcode/fake_event work.
6824 7 February 2007: Wouter
6825 - return answer with the same ID as query was sent with.
6826 - created udp forwarder test. I've done some effort to make it perform
6827 quickly. After servers are created, no big sleep statements but
6828 it checks the logfiles to see if servers have come up. Takes 0.14s.
6829 - set addrlen value when calling recvfrom.
6830 - comparison of addrs more portable.
