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

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

- tag 1.4.15rc1 created
- updated libunbound/ubsyms.def and remade tag 1.4.15rc1.
17 January 2012: Wouter
- Fix bug where canonical_compare of RRSIG did not downcase the
signer-name. This is mostly harmless because RRSIGs do not have
to be sorted in canonical order, usually.
12 January 2012: Wouter
- bug#428: add ub_version() call to libunbound. API version increase,
with (binary) backwards compatibility for the previous version.
10 January 2012: Wouter

leak one Mb, such failures are also usually logged), reported by
Robert Fleischmann.
- iana portlist updated.
19 December 2011: Wouter
- Fix for VU#209659 CVE-2011-4528: Unbound denial of service

ssl-service.pem.
- iana portlist updated.
- fix -flto detection on Lion for llvm-gcc.
31 October 2011: Wouter
- dns over ssl support, ssl-service-pem and ssl-service-key files
can be given and then TCP queries are serviced wrapped in SSL.
27 October 2011: Wouter
- lame-ttl and lame-size options no longer exist, it is integrated
with the host info. They are ignored (with verbose warning) if
encountered to keep the config file backwards compatible.

overwritten if a jostled out query causes a waiting query to be
resumed that then fails and sends an error message. (Thanks to
Matthew Lee).
21 October 2011: Wouter
- fix --enable-allsymbols, fptr wlist is disabled on windows with this
option enabled because of memory layout exe vs dll.
19 October 2011: Wouter
- fix unbound-anchor for broken strptime on OSX lion, detected
in configure.
- Detect if GOST really works, openssl1.0 on OSX fails.
- Implement ipv6%interface notation for scope_id usage.
17 October 2011: Wouter
- better documentation for inform_super (Thanks Yang Zhe).
14 October 2011: Wouter
- Fix for out-of-memory condition in libunbound (thanks
Robert Fleischman).
13 October 2011: Wouter
- Fix --enable-allsymbols, it depended on link specifics of the
target platform, or fptr_wlist assertion failures could occur.
12 October 2011: Wouter
- updated contrib/unbound_munin_ to family=auto so that it works with
munin-node-configure automatically (if installed as
/usr/local/share/munin/plugins/unbound_munin_ ).
27 September 2011: Wouter
- unbound.exe -w windows option for start and stop service.
23 September 2011: Wouter
- TCP-upstream calculates tcp-ping so server selection works if there
are alternatives.
20 September 2011: Wouter
- Fix classification of NS set in answer section, where there is a
parent-child server, and the answer has the AA flag for dir.slb.com.
Thanks to Amanda Constant from Secure64.
16 September 2011: Wouter
- fix bug #408: accept patch from Steve Snyder that comments out
unused functions in lookup3.c.
- iana portlist updated.
- fix EDNS1480 change memleak and TCP fallback.
- fix various compiler warnings (reported by Paul Wouters).
- max sent count. EDNS1480 only for rtt < 5000. No promiscuous
fetch if sentcount > 3, stop query if sentcount > 16. Count is
reset when referral or CNAME happens. This makes unbound better
at managing large NS sets, they are explored when there is continued
interest (in the form of queries).
15 September 2011: Wouter
- release 1.4.13.
- trunk contains 1.4.14 in development.
- Unbound probes at EDNS1480 if there an EDNS0 timeout.
12 September 2011: Wouter
- Reverted dns EDNS backoff fix, it did not help and needs
fragmentation fixes instead.
- tag 1.4.13rc2
7 September 2011: Wouter
- Fix operation in ipv6 only (do-ip4: no) mode.
6 September 2011: Wouter
- fedora specfile updated.
5 September 2011: Wouter
- tag 1.4.13rc1
2 September 2011: Wouter
- iana portlist updated.
26 August 2011: Wouter
- Fix num-threads 0 does not segfault, reported by Simon Deziel.
- Fix validation failures due to EDNS backoff retries, the retry
for fetch of data has want_dnssec because the iter_indicate_dnssec
function returns true when validation failure retry happens, and
then the serviced query code does not fallback to noEDNS, even if
the cache says it has this. This helps for DLV deployment when
the DNSSEC status is not known for sure before the lookup concludes.
24 August 2011: Wouter
- Applied patch from Karel Slany that fixes a memory leak in the
unbound python module, in string conversions.
22 August 2011: Wouter
- Fix validation of qtype ANY responses with CNAMEs (thanks Cathy
Zhang and Luo Ce). Unbound responds with the RR types that are
available at the name for qtype ANY and validates those RR types.
It does not test for completeness (i.e. with NSEC or NSEC3 query),
and it does not follow the CNAME or DNAME to another name (with
even more data for the already large response).
- Fix that internally, CNAMEs with NXDOMAIN have that as rcode.
- Documented the options that work with control set_option command.
- tcp-upstream yes/no option (works with set_option) for tunnels.
18 August 2011: Wouter
- fix autoconf call in makedist crosscompile to RC or snapshot.
17 August 2011: Wouter

1 August 2011: Wouter
- Fix autoconf 2.68 warnings
14 July 2011: Wouter
- Unbound implements RFC6303 (since version 1.4.7).
- tag 1.4.12rc1 is released as 1.4.12 (without the other fixes in the
meantime, those are for 1.4.13).
- iana portlist updated.
13 July 2011: Wouter
- Quick fix for contrib/unbound.spec example, no ldns-builtin any more.
11 July 2011: Wouter
- Fix wildcard expansion no-data reply under an optout NSEC3 zone is
validated as insecure, reported by Jia Li (lijia@cnnic.cn).
4 July 2011: Wouter
- 1.4.12rc1 tag created.
1 July 2011: Wouter
- version number in example config file.
- fix that --enable-static-exe does not complain about it unknown.
30 June 2011: Wouter
- tag relase 1.4.11, trunk is 1.4.12 development.
- iana portlist updated.
- fix bug#395: id bits of other query may leak out under conditions
- fix replyaddr count wrong after jostled queries, which leads to
eventual starvation where the daemon has no replyaddrs left to use.
- fix comment about rndc port, that referred to the old port number.
- fix that the listening socket is not closed when too many remote
control connections are made at the same time.
- removed ldns-src tarball inside the unbound tarball.
23 June 2011: Wouter
- Changed -flto check to support clang compiler.
- tag 1.4.11rc3 created.
17 June 2011: Wouter
- tag 1.4.11rc1 created.
- remove warning about signed/unsigned from flex (other flex version).
- updated aclocal.m4 and libtool to match.
- tag 1.4.11rc2 created.
16 June 2011: Wouter
- log-queries: yesno option, default is no, prints querylog.
- version is 1.4.11.
14 June 2011: Wouter
- Use -flto compiler flag for link time optimization, if supported.
- iana portlist updated.
12 June 2011: Wouter
- IPv6 service address for d.root-servers.net (2001:500:2D::D).
10 June 2011: Wouter
- unbound-control has version number in the header,
UBCT[version]_space_ is the header sent by the client now.
- Unbound control port number is registered with IANA:
ub-dns-control 8953/tcp unbound dns nameserver control
This is the new default for the control-port config setting.
- statistics-interval prints the number of jostled queries to log.
30 May 2011: Wouter
- Fix Makefile for U in environment, since wrong U is more common than
deansification necessity.
- iana portlist updated.
- updated ldns tarball to 1.6.10rc2 snapshot of today.
25 May 2011: Wouter
- Fix assertion failure when unbound generates an empty error reply
in response to a query, CVE-2011-1922 VU#531342.
- This fix is in tag 1.4.10.
- defense in depth against the above bug, an error is printed to log
instead of an assertion failure.
10 May 2011: Wouter
- bug#386: --enable-allsymbols option links all binaries to libunbound
and reduces install size significantly.
- feature, ignore-cd-flag: yesno to provide dnssec to legacy servers.
- iana portlist updated.
- Fix TTL of SOA so negative TTL is separately cached from normal TTL.
14 April 2011: Wouter
- configure created with newer autoconf 2.66.
12 April 2011: Wouter
- bug#378: Fix that configure checks for ldns_get_random presence.
8 April 2011: Wouter
- iana portlist updated.
- queries with CD flag set cause DNSSEC validation, but the answer is
not withheld if it is bogus. Thus, unbound will retry if it is bad
and curb the TTL if it is bad, thus protecting the cache for use by
downstream validators.
- val-override-date: -1 ignores dates entirely, for NTP usage.
29 March 2011: Wouter
- harden-below-nxdomain: changed so that it activates when the
cached nxdomain is dnssec secure. This avoids backwards
incompatibility because those old servers do not have dnssec.
24 March 2011: Wouter
- iana portlist updated.
- release 1.4.9.
- trunk is 1.5.0
17 March 2011: Wouter

28 January 2011: Wouter
- Fix remove private address does not throw away entire response.
24 January 2011: Wouter
- release 1.4.8
19 January 2011: Wouter
- fix bug#349: no -L/usr for ldns.
18 January 2011: Wouter
- ldns 1.6.8 tarball included.
- release 1.4.8rc1.
17 January 2011: Wouter
- add get and set option for harden-below-nxdomain feature.
- iana portlist updated.
14 January 2011: Wouter
- Fix so a changed NS RRset does not get moved name stuck on old
server, for type NS the TTL is not increased.
13 January 2011: Wouter
- Fix prefetch so it does not get stuck on old server for moved names.
12 January 2011: Wouter
- iana portlist updated.

- faster lruhash get_mem routine.
4 January 2011: Wouter
- bug#346: remove ITAR scripts from contrib, the service is discontinued, use the root.
- iana portlist updated.
23 December 2010: Wouter
- Fix in infra cache that could cause rto larger than TOP_TIMEOUT kept.
21 December 2010: Wouter
- algorithm compromise protection using the algorithms signalled in
the DS record. Also, trust anchors, DLV, and RFC5011 receive this,
and thus, if you have multiple algorithms in your trust-anchor-file
then it will now behave different than before. Also, 5011 rollover
for algorithms needs to be double-signature until the old algorithm
is revoked.
It is not an option, because I see no use to turn the security off.
- iana portlist updated.
17 December 2010: Wouter
- squelch 'tcp connect: bla' in logfile, (set verbosity 2 to see them).
- fix validation in this case: CNAME to nodata for co-hosted opt-in
NSEC3 insecure delegation, was bogus, fixed to be insecure.
16 December 2010: Wouter
- Fix our 'BDS' license (typo reported by Xavier Belanger).
10 December 2010: Wouter
- iana portlist updated.
- review changes for unbound-anchor.

- feature typetransparent localzone, does not block other RR types.
1 December 2010: Wouter
- Fix bug#338: print address when socket creation fails.
30 November 2010: Wouter
- Fix storage of EDNS failures in the infra cache.
- iana portlist updated.
18 November 2010: Wouter
- harden-below-nxdomain option, default off (because very old
software may be incompatible). We could enable it by default in
the future.
17 November 2010: Wouter
- implement draft-vixie-dnsext-resimprove-00, we stop on NXDOMAIN.
- make test output nicer.
15 November 2010: Wouter
- silence 'tcp connect: broken pipe' and 'net down' at low verbosity.
- iana portlist updated.
- so-sndbuf option for very busy servers, a bit like so-rcvbuf.
9 November 2010: Wouter
- unbound-anchor compiles with openssl 0.9.7.
8 November 2010: Wouter
- release tag 1.4.7.
- trunk is version 1.4.8.
- Be lenient and accept imgw.pl malformed packet (like BIND).
5 November 2010: Wouter
- do not synthesize a CNAME message from cache for qtype DS.
4 November 2010: Wouter
- Use central entropy to seed threads.
3 November 2010: Wouter
- Change the rtt used to probe EDNS-timeout hosts to 1000 msec.
2 November 2010: Wouter
- tag 1.4.7rc1.
- code review.
1 November 2010: Wouter
- GOST code enabled by default (RFC 5933).
27 October 2010: Wouter
- Fix uninit value in dump_infra print.
- Fix validation failure for parent and child on same server with an
insecure childzone and a CNAME from parent to child.
- Configure detects libev-4.00.
26 October 2010: Wouter
- dump_infra and flush_infra commands for unbound-control.
- no timeout backoff if meanwhile a query succeeded.
- Change of timeout code. No more lost and backoff in blockage.
At 12sec timeout (and at least 2x lost before) one probe per IP
is allowed only. At 120sec, the IP is blocked. After 15min, a
120sec entry has a single retry packet.
25 October 2010: Wouter
- Configure errors if ldns is not found.
22 October 2010: Wouter
- Windows 7 fix for the installer.
21 October 2010: Wouter
- Fix bug where fallback_tcp causes wrong roundtrip and edns
observation to be noted in cache. Fix bug where EDNSprobe halted
exponential backoff if EDNS status unknown.
- new unresponsive host method, exponentially increasing block backoff.
- iana portlist updated.
20 October 2010: Wouter
- interface automatic works for some people with ip6 disabled.
Therefore the error check is removed, so they can use the option.
19 October 2010: Wouter
- Fix for request list growth, if a server has long timeout but the
lost counter is low, then its effective rtt is the one without
exponential backoff applied. Because the backoff is not working.
The lost counter can then increase and the server is blacklisted,
or the lost counter does not increase and the server is working
for some queries.
18 October 2010: Wouter
- iana portlist updated.
13 October 2010: Wouter
- Fix TCP so it uses a random outgoing-interface.
- unbound-anchor handles ADDPEND keystate.
11 October 2010: Wouter
- Fix bug when DLV below a trust-anchor that uses NSEC3 optout where
the zone has a secure delegation hosted on the same server did not
verify as secure (it was insecure by mistake).
- iana portlist updated.
- ldns tarball updated (for reading cachedumps with bad RR data).
1 October 2010: Wouter
- test for unbound-anchor. fix for reading certs.
- Fix alloc_reg_release for longer uptime in out of memory conditions.
28 September 2010: Wouter
- unbound-anchor working, it creates or updates a root.key file.
Use it before you start the validator (e.g. at system boot time).
27 September 2010: Wouter
- iana portlist updated.
24 September 2010: Wouter
- bug#329: in example.conf show correct ipv4 link-local 169.254/16.
23 September 2010: Wouter
- unbound-anchor app, unbound requires libexpat (xml parser library).
22 September 2010: Wouter
- compliance with draft-ietf-dnsop-default-local-zones-14, removed
reverse ipv6 orchid prefix from builtin list.
- iana portlist updated.
17 September 2010: Wouter
- DLV has downgrade protection again, because the RFC says so.
- iana portlist updated.
16 September 2010: Wouter
- Algorithm rollover operational reality intrudes, for trust-anchor,
5011-store, and DLV-anchor if one key matches it's good enough.
- iana portlist updated.
- Fix reported validation error in out of memory condition.
15 September 2010: Wouter
- Abide RFC5155 section 9.2: no AD flag for replies with NSEC3 optout.
14 September 2010: Wouter
- increased mesh-max-activation from 1000 to 3000 for crazy domains
like _tcp.slb.com with 262 servers.
- iana portlist updated.
13 September 2010: Wouter
- bug#327: Fix for cannot access stub zones until the root is primed.
9 September 2010: Wouter
- unresponsive servers are not completely blacklisted (because of
firewalls), but also not probed all the time (because of the request
list size it generates). The probe rate is 1%.
- iana portlist updated.
20 August 2010: Wouter
- openbsd-lint fixes: acl_list_get_mem used if debug-alloc enabled.
iterator get_mem includes priv_get_mem. delegpt nodup removed.
listen_pushback, query_info_allocqname, write_socket, send_packet,
comm_point_set_cb_arg and listen_resume removed.
19 August 2010: Wouter
- Fix bug#321: resolution of rs.ripe.net artifacts with 0x20.
Delegpt structures checked for duplicates always.
No more nameserver lookups generated when depth is full anyway.
- example.conf notes how to do DNSSEC validation and track the root.
- iana portlist updated.
18 August 2010: Wouter
- Fix bug#322: configure does not respect CFLAGS on Solaris.
Pass CFLAGS="-xO4 -xtarget=generic" on the configure command line
if use sun-cc, but some systems need different flags.
16 August 2010: Wouter
- Fix acx_nlnetlabs.m4 configure output for autoconf-2.66 AS_TR_CPP
changes, uses m4_bpatsubst now.
- make test (or make check) should be more portable and run the unit
test and testbound scripts. (make longtest has special requirements).
13 August 2010: Wouter
- More pleasant remote control command parsing.
- documentation added for return values reported by doxygen 1.7.1.
- iana portlist updated.
9 August 2010: Wouter
- Fix name of rrset printed that failed validation.
5 August 2010: Wouter
- Return NXDOMAIN after chain of CNAMEs ends at name-not-found.

- updated ldns tarball with bugfixes.
- release tag 1.4.6.
- trunk becomes 1.4.7 develop.
- iana portlist updated.
22 July 2010: Wouter
- more error details on failed remote control connection.
15 July 2010: Wouter
- rlimit adjustments for select and ulimit can happen at the same time.
14 July 2010: Wouter
- Donation text added to README.
- Fix integer underflow in prefetch ttl creation from cache. This
fixes a potential negative prefetch ttl.
12 July 2010: Wouter
- Changed the defaults for num-queries-per-thread/outgoing-range.
For builtin-select: 512/960, for libevent 1024/4096 and for
windows 24/48 (because of win api). This makes the ratio this way
to improve resilience under heavy load. For high performance, use
libevent and possibly higher numbers.
10 July 2010: Wouter
- GOST enabled if SSL is recent and ldns has GOST enabled too.
- ldns tarball updated.
9 July 2010: Wouter
- iana portlist updated.
- Fix validation of qtype DNSKEY when a key-cache entry exists but
no rr-cache entry is used (it expired or prefetch), it then goes
back up to the DS or trust-anchor to validate the DNSKEY.
7 July 2010: Wouter
- Neat function prototypes, unshadowed local declarations.
6 July 2010: Wouter
- failure to chown the pidfile is not fatal any more.
- testbound uses UTC timezone.
- ldns tarball updated (ports and works on Minix 3.1.7). On Minix, add
/usr/gnu/bin to PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
5 July 2010: Wouter
- log if a server is skipped because it is on the donotquery list,
at verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
- added feature to print configure date, target and options with -h.
- added feature to print event backend system details with -h.
- wdiff is not actually required by make test, updated requirements.
1 July 2010: Wouter
- Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
must be signed with all algorithms from the DS rrset at the parent.
This is now checked and becomes bogus if not.
28 June 2010: Wouter
- Fix jostle list bug found by Vince (luoce@cnnic), it caused the qps
in overload situations to be about 5 qps for the class of shortly
serviced queries.
The capacity of the resolver is then about (numqueriesperthread / 2)
/ (average time for such long queries) qps for long queries.
And about (numqueriesperthread / 2)/(jostletimeout in whole seconds)
qps for short queries, per thread.
- Fix the max number of reply-address count to be applied for duplicate
queries, and not for new query list entries. This raises the memory
usage to a max of (16+1)*numqueriesperthread reply addresses.
25 June 2010: Wouter
- Fix handling of corner case reply from lame server, follows rfc2308.
It could lead to a nodata reply getting into the cache if the search
for a non-lame server turned up other misconfigured servers.
- unbound.h has extern "C" statement for easier include in c++.
23 June 2010: Wouter
- iana portlist updated.
- makedist upgraded cross compile openssl option, like this:
./makedist.sh -s -wssl openssl-1.0.0a.tar.gz -w --enable-gost
22 June 2010: Wouter
- Unbound reports libev or libevent correctly in logs in verbose mode.
- Fix to unload gost dynamic library module for leak testing.
18 June 2010: Wouter
- iana portlist updated.
17 June 2010: Wouter
- Add AAAA to root hints for I.ROOT-SERVERS.NET.
16 June 2010: Wouter
- Fix assertion failure reported by Kai Storbeck from XS4ALL, the
assertion was wrong.
- updated ldns tarball.
15 June 2010: Wouter
- tag 1.4.5 created.
- trunk contains 1.4.6 in development.
- Fix TCPreply on systems with no writev, if just 1 byte could be sent.
- Fix to use one pointer less for iterator query state store_parent_NS.
- makedist crosscompile to windows uses builtin ldns not host ldns.
- Max referral count from 30 to 130, because 128 one character domains
is valid DNS.
- added documentation for the histogram printout to syslog.
11 June 2010: Wouter
- When retry to parent the retrycount is not wiped, so failed
nameservers are not tried again.
- iana portlist updated.
10 June 2010: Wouter
- Fix bug where a long loop could be entered, now cycle detection
has a loop-counter and maximum search amount.
4 June 2010: Wouter
- iana portlist updated.
- 1.4.5rc1 tag created.
3 June 2010: Wouter
- ldns tarball updated, 1.6.5.
- review comments, split dependency cycle tracking for parentside
last resort lookups for A and AAAA so there are more lookup options.
2 June 2010: Wouter
- Fix compile warning if compiled without threads.
- updated ldns-tarball with current ldns svn (pre 1.6.5).
- GOST disabled-by-default, the algorithm number is allocated but the
RFC is still has to pass AUTH48 at the IETF.
1 June 2010: Wouter
- Ignore Z flag in incoming messages too.
- Fix storage of negative parent glue if that last resort fails.
- libtoolize 2.2.6b, autoconf 2.65 applied to configure.
- new splint flags for newer splint install.
31 May 2010: Wouter
- Fix AD flag handling, it could in some cases mistakenly copy the AD
flag from upstream servers.
- alloc_special_obtain out of memory is not a fatal error any more,
enabling unbound to continue longer in out of memory conditions.
- parentside names are dispreferred but not said to be dnssec-lame.
- parentside check for cached newname glue.
- fix parentside and querytargets modulestate, for dump_requestlist.
- unbound-control-setup makes keys -rw-r--- so not all users permitted.
- fix parentside from cache to be marked dispreferred for bad names.
28 May 2010: Wouter
- iana portlist updated.
- parent-child disagreement approach altered. Older fixes are
removed in place of a more exhaustive search for misconfigured data
available via the parent of a delegation.
This is designed to be throttled by cache entries, with TTL from the
parent if possible. Additionally the loop-counter is used.
It also tests for NS RRset differences between parent and child.
The fetch of misconfigured data should be more reliable and thorough.
It should work reliably even with no or only partial data in cache.
Data received from the child (as always) is deemed more
authoritative than information received from the delegation parent.
The search for misconfigured data is not performed normally.
26 May 2010: Wouter
- Contribution from Migiel de Vos (Surfnet): nagios patch for
unbound-host, in contrib/ (in the source tarball). Makes
unbound-host suitable for monitoring dnssec(-chain) status.
21 May 2010: Wouter
- EDNS timeout code will not fire if EDNS status already known.
- EDNS failure not stored if EDNS status known to work.
19 May 2010: Wouter
- Fix resolution for domains like safesvc.com.cn. If the iterator
can not recurse further and it finds the delegation in a state
where it would otherwise have rejected it outhand if so received
from a cache lookup, then it can try to ask higherup (with loop
protection).
- Fix comments in iter_utils:dp_is_useless.
18 May 2010: Wouter
- Fix various compiler warnings from the clang llvm compiler.
- iana portlist updated.
6 May 2010: Wouter
- Fix bug#308: spelling error in variable name in parser and lexer.
4 May 2010: Wouter
- Fix dnssec-missing detection that was turned off by server selection.
- Conforms to draft-ietf-dnsop-default-local-zones-13. Added default
reverse lookup blocks for IPv4 test nets 100.51.198.in-addr.arpa,
113.0.203.in-addr.arpa and Orchid prefix 0.1.1.0.0.2.ip6.arpa.
29 April 2010: Wouter
- Fix for dnssec lameness detection to use the key cache.
- infra cache entries that are expired are wiped clean. Previously
it was possible to not expire host data (if accessed often).
28 April 2010: Wouter
- ldns tarball updated and GOST support is detected and then enabled.
- iana portlist updated.
- Fix detection of gost support in ldns (reported by Chris Smith).
27 April 2010: Wouter
- unbound-control get_option domain-insecure shows config file items.
- fix retry sequence if prime hints are recursion-lame.
- autotrust anchor file can be initialized with a ZSK key as well.
- harden-referral-path does not result in failures due to max-depth.
You can increase the max-depth by adding numbers (' 0') after the
target-fetch-policy, this increases the depth to which is checked.

- Compile fix using Sun Studio 12 compiler on Solaris 5.9, use
CPPFLAGS during configure process.
- if libev is installed on the base system (not libevent), detect
it from the event.h header file and link with -lev.
- configlexer.lex gets config.h, and configyyrename.h added by make,
no more double include.
- More strict scrubber (Thanks to George Barwood for the idea):
NS set must be pertinent to the query (qname subdomain nsname).
- Fix bug#307: In 0x20 backoff fix fallback so the number of
outstanding queries does not become -1 and block the request.
Fixed handling of recursion-lame in combination with 0x20 fallback.
Fix so RRsets are compared canonicalized and sorted if the immediate
comparison fails, this makes it work around round-robin sites.
23 April 2010: Wouter
- Squelch log message: sendto failed permission denied for
255.255.255.255, it is visible in VERB_DETAIL (verbosity 2).
- Fix to fetch data as last resort more tenaciously. When cycle
targets cause the server selection to believe there are more options
when they really are not there, the server selection is reinitiated.
- Fix fetch from blacklisted dnssec lame servers as last resort. The
server's IP address is then given in validator errors as well.
- Fix local-zone type redirect that did not use the query name for
the answer rrset.
22 April 2010: Wouter
- tag 1.4.4.
- trunk contains 1.4.5 in development.
- Fix validation failure for qtype ANY caused by a RRSIG parse failure.
The validator error message was 'no signatures from ...'.
16 April 2010: Wouter
- more portability defines for CMSG_SPACE, CMSG_ALIGN, CMSG_LEN.
- tag 1.4.4rc1.
15 April 2010: Wouter
- ECC-GOST algorithm number 12 that is assigned by IANA. New test
example key and signatures for GOST. GOST requires openssl-1.0.0.
GOST is still disabled by default.
9 April 2010: Wouter
- Fix bug#305: pkt_dname_tolower could read beyond end of buffer or
get into an endless loop, if 0x20 was enabled, and buffers are small
or particular broken packets are received.
- Fix chain of trust with CNAME at an intermediate step, for the DS
processing proof.
8 April 2010: Wouter
- Fix validation of queries with wildcard names (*.example).
6 April 2010: Wouter
- Fix EDNS probe for .de DNSSEC testbed failure, where the infra
cache timeout coincided with a server update, the current EDNS
backoff is less sensitive, and does not cache the backoff unless
the backoff actually works and the domain is not expecting DNSSEC.
- GOST support with correct algorithm numbers.
1 April 2010: Wouter
- iana portlist updated.
24 March 2010: Wouter
- unbound control flushed items are not counted when flushed again.
23 March 2010: Wouter
- iana portlist updated.
22 March 2010: Wouter
- unbound-host disables use-syslog from config file so that the
config file for the main server can be used more easily.
- fix bug#301: unbound-checkconf could not parse interface
'0.0.0.0@5353', even though unbound itself worked fine.
19 March 2010: Wouter
- fix fwd_ancil test to pass if the socket options are not supported.
18 March 2010: Wouter
- Fixed random numbers for port, interface and server selection.
Removed very small bias.
- Refer to the listing in unbound-control man page in the extended
statistics entry in the unbound.conf man page.
16 March 2010: Wouter
- Fix interface-automatic for OpenBSD: msg.controllen was too small,
also assertions on ancillary data buffer.
- check for IP_SENDSRCADDR for interface-automatic or IP_PKTINFO.
- for NSEC3 check if signatures are cached.
15 March 2010: Wouter
- unit test for util/regional.c.
12 March 2010: Wouter
- Reordered configure checks so fork and -lnsl -lsocket checks are
earlier, and thus later checks benefit from and do not hinder them.
- iana portlist updated.
- ldns tarball updated.
- Fix python use when multithreaded.
- Fix solaris python compile.
- Include less in config.h and include per code file for ldns, ssl.
11 March 2010: Wouter
- another memory allocation option: --enable-alloc-nonregional.
exposes the regional allocations to other memory purifiers.
- fix for memory alignment in struct sock_list allocation.
- Fix for MacPorts ldns without ssl default, unbound checks if ldns
has dnssec functionality and uses the builtin if not.
- Fix daemonize on Solaris 10, it did not detach from terminal.
- tag 1.4.3 created.
- trunk is 1.4.4 in development.
- spelling fix in validation error involving cnames.
10 March 2010: Wouter
- --enable-alloc-lite works with test set.
- portability in the testset: printf format conversions, prototypes.
