- DLV is going to be decommissioned. Advice to stop using it, and
put text in the example configuration and man page to that effect.
10 May 2015: Wouter
- Change syntax of particular validator error to be easier for

10 April 2015: Wouter
- unbound-control ratelimit_list lists high rate domains.

- Fix#663: ssl handshake fails when using unix socket because dh size
is too small.

- Libunbound skips dos-line-endings from etc/hosts.
- Unbound exits with a fatal error when the auto-trust-anchor-file
fails to be writable. This is seconds after startup. You can
load a readonly auto-trust-anchor-file with trust-anchor-file.
The file has to be writable to notice the trust anchor change,
without it, a trust anchor change will be unnoticed and the system
will then become inoperable.
- unbound-control list_insecure command shows the negative trust
anchors currently configured, patch from Jelte Jansen.
2 April 2015: Wouter
- Fix #660: Fix interface-automatic broken in the presence of
asymmetric routing.

4 March 2015: Wouter
- Patch from Brad Smith that syncs compat/getentropy_linux with
OpenBSD's version (2015-03-04).

comparisons (except if all responses are errors),
inability to find nameservers does not fail equality comparisons,
many nameservers does not try to compare more than max-sent-count,
parse failures start 0x20 fallback procedure.

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

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

parse sldns.
30 January 2014: Wouter

if there are no changes.
- delay-close: msec option that delays closing ports for which
the UDP reply has timed out. Keeps the port open, only accepts
the correct reply. This correct reply is not used, but the port
is open so that no port-denied ICMPs are generated.
27 January 2014: Wouter

--with-ldns is needed and unbound does not rely on libldns.
- portability fixes for new USE_SLDNS ldns subdir codebase.
22 Oct 2013: Wouter
- Patch from Neel Goyal: Add an API call to set an event base on an
existing ub_ctx. This basically just destroys the current worker and
sets the event base to the current. And fix a deadlock in
ub_resolve_event – the cfglock is held when libworker_create is
called. This ends up trying to acquire the lock again in
context_obtain_alloc in the call chain.
- Fix #528: if very high logging (4 or more) segfault on allow_snoop.
26 Sep 2013: Wouter
- unbound-event.h is installed if configured --with-libevent. It

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

- iana portlist updated.
10 February 2012: Wouter
- Slightly smaller critical region in one case in infra cache.
- Fix timeouts to keep track of query type, A, AAAA and other, if

- unit test fix for nomem_cnametopos.rpl race condition.
9 February 2012: Wouter
- Fix AHX_BROKEN_MEMCMP for autoheader mess up of #undef in config.h.
8 February 2012: Wouter
- 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.

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.

succeeds, replace the real key file. So failures leave a useful file.
18 January 2012: Wouter
- 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

leak one Mb, such failures are also usually logged), reported by
Robert Fleischmann.

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

server selection for choosing out of a (particular) list of bad
choices. (bug#415)
- Fix make_new_space function so that the incoming query is not
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.

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.

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

- 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

- 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

12 January 2011: Wouter
- iana portlist updated.

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

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.

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.

- 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.

- 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.

- 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.

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.

- 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.
26 April 2010: Wouter
- 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.

- 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

Removed very small bias.
- Refer to the listing in unbound-control man page in the extended
statistics entry in the unbound.conf man page.

- 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.

list_local_data.
24 February 2010: Wouter
- Fix scrubber bug that potentially let NS records through. Reported
by Amanda Constant.
- Also delete potential poison references from additional.
- Fix: no classification of a forwarder as lame, throw away instead.
23 February 2010: Wouter
- libunbound ub_ctx_get_option() added.
- unbound-control set_option and get_option commands.
- iana portlist updated.
18 February 2010: Wouter

- unbound-control log_reopen command.
- moved get_option code from unbound-checkconf to util/config_file.c
17 February 2010: Wouter
- Disregard DNSKEY from authority section for chain of trust.
DS records that are irrelevant to a referral scrubbed. Anti-poison.
- iana portlist updated.
16 February 2010: Wouter
- Check for 'no space left on device' (or other errors) when
writing updated autotrust anchors and print errno to log.
15 February 2010: Wouter
- Fixed the requery protection, the TTL was 0, it is now 900 seconds,
hardcoded. We made the choice to send out more conservatively,
protecting against an aggregate effect more than protecting a
single user (from their own folly, perhaps in case of misconfig).
12 February 2010: Wouter
- Re-query pattern changed on validation failure. To protect troubled
authority servers, unbound caches a failure for the DNSKEY or DS
records for the entire zone, and only retries that 900 seconds later.
This implies that only a handful of packets are sent extra to the
authority if the zone fails.
11 February 2010: Wouter
- ldns tarball update for long label length syntax error fix.
- iana portlist updated.
9 February 2010: Wouter

20 January 2010: Wouter
- Fixup lookup trouble for parent-child domains on the first query.
14 January 2010: Wouter
- Fixup ldns detection to also check for header files.
13 January 2010: Wouter
- prefetch-key option that performs DNSKEY queries earlier in the
validation process, and that could halve the latency on DNSSEC
queries. It takes some extra processing (CPU, a cache is needed).
12 January 2010: Wouter
- Fix unbound-checkconf for auto-trust-anchor-file present checks.
8 January 2010: Wouter
- Fix for parent-child disagreement code which could have trouble
when (a) ipv6 was disabled and (b) the TTL for parent and child
were different. There were two bugs, the parent-side information
is fixed to no longer block lookup of child side information and
the iterator is fixed to no longer attempt to get ipv6 when it is
not enabled and then give up in failure.
- test and fixes to make prefetch actually store the answer in the
cache. Considers some rrsets 'already expired' but does not allow
overwriting of rrsets considered more secure.
7 January 2010: Wouter
- Fixup python documentation (thanks Leo Vandewoestijne).
- Work on cache prefetch feature.
- Stats for prefetch, in log print stats, unbound-control stats
and in unbound_munin plugin.
6 January 2010: Wouter

responses are now only used internally.
- Fix negative cache lookup of closestencloser check of DS type bit.
8 December 2009: Wouter
- Fix for lookup of parent-child disagreement domains, where the
parent-side glue works but it does not provide proper NS, A or AAAA
for itself, fixing domains such as motorcaravanners.eu.
- Feature: you can specify a port number in the interface: line, so
you can bind the same interface multiple times at different ports.
7 December 2009: Wouter

- Fix double time subtraction in negative cache reported by
Amanda Constant and Hugh Mahon.
- Made new validator error string available from libunbound for
applications. It is in result->why_bogus, a zero-terminated string.
unbound-host prints it by default if a result is bogus.
Also the errinf is public in module_qstate (for other modules).
7 October 2009: Wouter
- retry for validation failure in DS and prime results. Less mem use.
unit test. Provisioning in other tests for requeries.
- retry for validation failure in DNSKEY in middle of chain of trust.
unit test.
- retry for empty non terminals in chain of trust and unit test.
- Fixed security bug where the signatures for NSEC3 records were not
checked when checking for absence of DS records. This could have
enabled the substitution of an insecure delegation.
- moved version number to 1.4.0 because of 1.3.4 release with only
the NSEC3 patch from the entry above.
- val-log-level: 2 shows extended error information for validation
failures, but still one (longish) line per failure. For example:
validation failure <example.com. DNSKEY IN>: signature expired from
192.0.2.4 for trust anchor example.com. while building chain of trust
validation failure <www.example.com. A IN>: no signatures from
192.0.2.6 for key example.com. while building chain of trust
6 October 2009: Wouter
- Test set updated to provide additional ns lookup result.
The retry would attempt to fetch the data from other nameservers
for bogus data, and this needed to be provisioned in the tests.

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

They are performed to higherup domains, and thus treated as if
going to higher zones when looking up the right forward or stub
server. This makes a stub pointing to a local server that has
a local view of example.com signed with the same keys as are
publicly used work. Reported by Johan Ihren.

Reported by Paul Wouters.
- review comments from Matthijs.
2 June 2009: Wouter

- Fixup a crash-on-exit which was triggered by a very long queue.
Unbound would try to re-use ports that came free, but this is
of course not really possible because everything is deleted.
Most easily triggered on XP (not Vista), maybe because of the
network stack encouraging large messages backlogs.
- change in debug statements.
- Fixed bug that could cause a crash if root prime failed when there
were message backlogs.

definition. Trust anchors with no supported algos are ignored.
This means a (higher)DS or DLV entry for them could succeed, and
otherwise they are treated as insecure.
- domain-insecure: "example.com" statement added. Sets domain
insecure regardless of chain of trust DSs or DLVs. The inverse
of a trust-anchor.

6 February 2009: Wouter
- contrib contains specfile for fedora 1.2.1 (from Paul Wouters).
- iana portlist updated.
- fixup EOL in include directive (reported by Paul Wouters).
You can no longer specify newlines in the names of included files.
- config parser changed. Gives some syntax errors closer to where they
occurred. Does not enforce a space after keyword anymore.
Does not allow literal newlines inside quoted strings anymore.
- verbosity level 5 logs customer IP for new requestlist entries.
- test fix, lexer and cancel test.
- new option log-time-ascii: yes if you enable it prints timestamps
in the log file as Feb 06 13:45:26 (like syslog does).
- detect event_base_new in libevent-1.4.1 and later and use it.
- #231 unbound-checkconf -o option prints that value from config file.
Useful for scripting in management scripts and the like.
5 February 2009: Wouter
- ldns 1.5.0 rc as tarball included.
- 1.3.0 development continues:
change in libunbound API: ub_cancel can return an error, that
the async_id did not exist, or that it was already delivered.
The result could have been delivered just before the cancel
routine managed to acquire the lock, so a caller may get the
result at the same time they call cancel. For this case,
ub_cancel tries to return an error code.
Fixes race condition in ub_cancel() libunbound function.
- MacOSX Leopard cleaner text output from configure.
- initgroups(3) is called to drop secondary group permissions, if
applicable.
- configure option --with-ldns-builtin forces the use of the
inluded ldns package with the unbound source. The -I include
is put before the others, so it avoids bad include files from
an older ldns install.
- daemon(3) posix call is used when available.
- testbound test for older fix added.
4 February 2009: Wouter
- tag for release 1.2.1.
- trunk setup for 1.3.0 development.
3 February 2009: Wouter
- noted feature requests in doc/TODO.
- printout more detailed errors on ssl certificate loading failures.
- updated IANA portlist.
16 January 2009: Wouter
- more quiet about ipv6 network failures, i.e. when ipv6 is not
available (network unreachable). Debug still printed on high
verbosity.
- unbound-host -4 and -6 options. Stops annoying ipv6 errors when
debugging with unbound-host -4 -d ...
- more cycle detection for NS-check, addr-check, root-prime and
stub-prime queries in the iterator. Avoids possible deadlock
when priming fails.
15 January 2009: Wouter
- bug #229: fixup configure checks for compilation with Solaris
Sun cc compiler, ./configure CC=/opt/SUNWspro/bin/cc
- fixup suncc warnings.
- fix bug where unbound could crash using libevent 1.3 and older.
- update testset for recent retry change.
14 January 2009: Wouter
- 1.2.1 feature: negative caching for failed queries.
Queries that failed are cached for 5 seconds (NORR_TTL).
If the failure is local, like out of memory, it is not cached.
- the TTL comparison for the cache used different comparisons,
causing many cache responses that used the iterator and validator
state machines unnecessarily.
- retry from 4 to 5 so that EDNS drop retry is part of the first
query resolve attempt, and cached error does not stop EDNS fallback.
- remove debug prints that protect against bad referrals.
- honor QUIET=no on make commandline (or QUIET=yes ).
13 January 2009: Wouter
- fixed bug in lameness marking, removed printouts.
- find NS rrset more cleanly for qtype NS.
- Moved changes to 1.2.0 for release. Thanks to Mark Zealey for
reporting and logs.
- 1.2.1 feature: stops resolving AAAAs promiscuously when they
are in the negative cache.

statements. (Adapted from patch by Paul Wouters).
- typo fix and iana portlist updated.
- porting testsuite; unused var warning, and type fixup.
6 January 2009: Wouter
- fixup packet-of-death when compiled with --enable-debug.
A malformed packet could cause an internal assertion failure.
- added test for HINFO canonicalisation behaviour.
- fixup reported problem with transparent local-zone data where
queries with different type could get nxdomain. Now queries
with a different name get resolved normally, with different type
get a correct NOERROR/NODATA answer.
- HINFO no longer downcased for validation, making unbound compatible
with bind and ldns.
- fix reading included config files when chrooted.
Give full path names for include files.
Relative path names work if the start dir equals the working dir.
- fix libunbound message transport when no packet buffer is available.
5 January 2009: Wouter
- fixup getaddrinfo failure handling for remote control port.
- added L.ROOT-SERVERS.NET. AAAA 2001:500:3::42 to builtin root hints.

17 December 2008: Wouter
- follows ldns makedist.sh. -rc option. autom4te dir removed.
- unbound-control status command.
- extended statistics has a number of ipv6 queries counter.
contrib/unbound_munin_ was updated to draw ipv6 in the hits graph.
16 December 2008: Wouter
- follow makedist improvements from ldns, for maintainers prereleases.
- snapshot version uses _ not - to help rpm distinguish the
version number.
11 December 2008: Wouter
- better fix for bug #219: use LOG_NDELAY with openlog() call.
Thanks to Tamas Tevesz.
9 December 2008: Wouter
- bug #221 fixed: unbound checkconf checks if key files exist if
remote control is enabled. Also fixed NULL printf when not chrooted.
- iana portlist updated.
3 December 2008: Wouter
- Fix problem reported by Jaco Engelbrecht where unbound-control stats
freezes up unbound if this was compiled without threading, and
was using multiple processes.
- iana portlist updated.
- test for remote control with interprocess communication.
- created command distribution mechanism so that remote control
commands other than 'stats' work on all processes in a nonthreaded
compiled version. dump/load cache work, on the first process.
- fixup remote control local_data addition memory corruption bug.
1 December 2008: Wouter
- SElinux policy files in contrib/selinux for the unbound daemon,
by Paul Wouters and Adam Tkac.
25 November 2008: Wouter
- configure complains when --without-ssl is given (bug #220).
- skip unsupported feature tests on vista/mingw.
- fixup testcode/streamtcp to work on vista/mingw.
- root-hints test checks version of dig required.
- blacklisted servers are polled at a low rate (1%) to see if they
come back up. But not if there is some other working server.
24 November 2008: Wouter
- document that the user of the server daemon needs read privileges
on the keys and certificates generated by unbound-control-setup.
This is different per system or distribution, usually, running the
script under the same username as the server uses suffices.
i.e. sudo -u unbound unbound-control-setup
- testset port to vista/mingw.
- tcp_sigpipe to freebsd port.
21 November 2008: Wouter
- fixed tcp accept, errors were printed when they should not.
- unbound-control-setup.sh removes read/write permissions other
from the keys it creates (as suggested by Dmitriy Demidov).
20 November 2008: Wouter
- fixup fatal error due to faulty error checking after tcp accept.
- add check in rlimit to avoid integer underflow.
- rlimit check with new formula; better estimate for number interfaces
- nicer comments in rlimit check.
- tag 1.1.1 created in svn.

19 November 2008: Wouter
- bug #219: fixed so that syslog which delays opening until the first
log line is written, gets a log line while not chroot'ed yet.
18 November 2008: Wouter
- iana portlist updated.
- removed cast in unit test debug print that was not 64bit safe.
- trunk back to 1.1.0; copied to tags 1.1.0 release.
- trunk to has version number 1.1.1 again.
- in 1.1.1; make clean nicer. grammar in manpage.
17 November 2008: Wouter
- theoretical fix for problems reported on mailing list.
If a delegation point has no A but only AAAA and do-ip6 is no,
resolution would fail. Fixed to ask for the A and AAAA records.
It has to ask for both always, so that it can fail quietly, from
TLD perspective, when a zone is only reachable on one transport.
- test for above, only AAAA and doip6 is no. Fix causes A record
for nameserver to be fetched.
- fixup address duplication on cache fillup for delegation points.
- testset updated for new query answer requirements.
14 November 2008: Wouter
- created 1.1.0 release tag in svn.

6 November 2008: Wouter
- dname_priv must decompress the name before comparison.
- iana portlist updated.
5 November 2008: Wouter
- fixed possible memory leak in key_entry_key deletion.
Would leak a couple bytes when trust anchors were replaced.
- if query and reply qname overlap, the bytes are skipped not copied.
- fixed file descriptor leak when messages were jostled out that
had outstanding (TCP) replies.
- DNAMEs used from cache have their synthesized CNAMEs initialized
properly.
- fixed file descriptor leak for localzone type deny (for TCP).
- fixed memleak at exit for nsec3 negative cached zones.
- fixed memleak for the keyword 'nodefault' when reading config.
- made verbosity of 'edns incapable peer' warning higher, so you
do not get spammed by it.

error while unnecessarily try to listen to a closed fd. Fixed.
4 November 2008: Wouter
- fixed -Wwrite-strings warnings that result in better code.
3 November 2008: Wouter
- fixup build process for Mac OSX linker, use ldns b32 compat funcs.
- generated configure with autoconf-2.61.
- iana portlist updated.
- detect if libssl needs libdl. For static linking with libssl.
- changed to use new algorithm identifiers for sha256/sha512
from ldns 1.4.0 (need very latest version).
- updated the included ldns tarball.
- proper detection of SHA256 and SHA512 functions (not just sizes).
23 October 2008: Wouter
- a little more debug info for failure on signer names. prints names.
22 October 2008: Wouter
- CFLAGS are picked up by configure from the environment.
- iana portlist updated.
- updated ldns to use 1.4.0-pre20081022 so it picks up CFLAGS too.
- new stub-prime: yesno option. Default is off, so it does not prime.
can be turned on to get same behaviour as previous unbound release.
- made automated test that checks if builtin root hints are uptodate.
- finished draft-wijngaards-dnsext-resolver-side-mitigation
implementation. The unwanted-reply-threshold can be set.
- fixup so fptr_whitelist test in alloc.c works.
21 October 2008: Wouter
- fix update-anchors.sh, so it does not report different RR order
as an update. Sorts the keys in the file. Updated copyright.
- fixup testbound on windows, the command control pipe doesn't exist.
- skip 08hostlib test on windows, no fork() available.
- made unbound-remote work on windows.
20 October 2008: Wouter
- quench a log message that is debug only.
- iana portlist updated.
- do not query bogus nameservers. It is like nameservers that have
the NS or A or AAAA record bogus are listed as donotquery.
- if server selection is faced with only bad choices, it will
attempt to get more options to be fetched.
- changed bogus-ttl default value from 900 to 60 seconds.
In anticipation that operator caused failures are more likely than
actual attacks at this time. And thus repeated validation helps
the operators get the problem fixed sooner. It makes validation
failures go away sooner (60 seconds after the zone is fixed).
Also it is likely to try different nameserver targets every minute,
so that if a zone is bad on one server but not another, it is
likely to pick up the 'correct' one after a couple minutes,
and if the TTL is big enough that solves validation for the zone.
- fixup unbound-control compilation on windows.
17 October 2008: Wouter
- port Leopard/G5: fixup type conversion size_t/uint32.
please ranlib, stop file without symbols warning.
- harden referral path now also validates the root after priming.
It looks up the root NS authoritatively as well as the root servers
and attemps to validate the entries.
16 October 2008: Wouter
- Fixup negative TTL values appearing (reported by Attila Nagy).
15 October 2008: Wouter
- better documentation for 0x20; remove fallback TODO, it is done.
- harden-referral-path feature includes A, AAAA queries for glue,
as well as very careful NS caching (only when doing NS query).
A, AAAA use the delegation from the NS-query.
14 October 2008: Wouter
- fwd_three.tpkg test was flaky. If the three requests hit the
wrong threads by chance (or bad OS) then the test would fail.
Made less flaky by increasing number of retries.
- stub_udp.tpkg changed to work, give root hints. fixed ldns_dname_abs.
- ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081014).
Which includes the ldns_dname_absolute fix.
- fwd_three test remains flaky now that unbound does not stop
listening when full. Thus, removed timeout problem.
It may be serviced by three threads, or maybe by one.
Mostly only useful for lock-check testing now.
13 October 2008: Wouter
- fixed recursion servers deployed as authoritative detection, so
that as a last resort, a +RD query is sent there to get the
correct answer.
- iana port list update.
- ldns tarball is snapshot of ldns r2759 (1.4.0-pre-20081013).
10 October 2008: Wouter
- fixup tests - the negative cache contained the correct NSEC3s for
two tests that are supposed to fail to validate.
9 October 2008: Wouter
- negative cache caps max iterations of NSEC3 done.
- NSEC3 negative cache for qtype DS works.
8 October 2008: Wouter
- NSEC negative cache for DS.
6 October 2008: Wouter
- jostle-timeout option, so you can config for slow links.
- 0x20 fallback code. Tries 3xnumber of nameserver addresses
queries that must all be the same. Sent to random nameservers.
- documented choices for DoS, EDNS, 0x20.
2 October 2008: Wouter
- fixup unlink of pidfile.
- fixup SHA256 algorithm collation code.
- contrib/update-anchor.sh does not overwrite anchors if not needed.
exits 0 when a restart is needed, other values if not.
so, update-anchor.sh -d mydir && /etc/rc.d/unbound restart
can restart unbound exactly when needed.
30 September 2008: Wouter
- fixup SHA256 DS downgrade, no longer possible to downgrade to SHA1.
- tests for sha256 support and downgrade resistance.
- RSASHA256 and RSASHA512 support (using the draft in dnsext),
using the drafted protocol numbers.
- when using stub on localhost (127.0.0.1@10053) unbound works.
Like when running NSD to host a local zone, on the same machine.
The noprime feature. manpages more explanation. Added a test for it.
- shorthand for reverse PTR, local-data-ptr: "1.2.3.4 www.ex.com"
29 September 2008: Wouter
- EDNS lameness detection, if EDNS packets are dropped this is
detected, eventually.
- multiple query timeout rtt backoff does not backoff too much.
26 September 2008: Wouter

- testbound can pass time, increasing the internal timer.
- do not mark unsigned additionals bogus, leave unchecked, which
is removed too.
1 September 2008: Wouter
- disallow nonrecursive queries for cache snooping by default.
You can allow is using access-control: <subnet> allow_snoop.
The defaults do allow access no authoritative data without RD bit.
- two tests for it and fixups of tests for nonrec refused.
29 August 2008: Wouter
- version 1.1 number in trunk.
- harden-referral-path option for query for NS records.
Default turns off expensive, experimental option.
28 August 2008: Wouter
- fixup logfile handling; it is created with correct permissions
again. (from bugfix#199).
Some errors are not written to logfile (pidfile writing, forking),
and these are only visible by using the -d commandline flag.
27 August 2008: Wouter
- daemon(3) is causing problems for people. Reverting the patch.
bug#200, and 199 and 203 contain sideline discussion on it.

chroot and drop permissions.
- config option to set size of aggressive negative cache,
neg-cache-size.
- bug#203 fixed: dlv has been implemented.
26 August 2008: Wouter

12 August 2008: Wouter
- finished adjusting testset to provide qtype NS answers.
11 August 2008: Wouter
- Fixup rrset security updates overwriting 2181 trust status.
This makes validated to be insecure data just as worthless as
nonvalidated data, and 2181 rules prevent cache overwrites to them.
- Fix assertion fail on bogus key handling.
- dnssec lameness detection works on first query at trust apex.
- NS queries get proper cache and dnssec lameness treatment.
- fixup compilation without pthreads on linux.
8 August 2008: Wouter

- minitpkg shows skipped tests in report.
- skip ipv6 tests on ipv4 only hosts (requires only ipv6 localhost not
ipv6 connectivity).
- winsock event handler keeps track of sticky TCP events, that have
not been fully handled yet. when interest in the event(s) resumes,
they are sent again. When WOULDBLOCK is returned events are cleared.
- skip tests that need signals when testing on mingw.
18 June 2008: Wouter
- open testbound replay files in binary mode, because fseek/ftell
do not work in ascii-mode on windows. The b does nothing on unix.
unittest and testbound tests work on windows (xp too).
- ioctlsocket prints nicer error message.
- fixed up some TCP porting for winsock.
- lack of IPv6 gives a warning, no fatal error.
- use WSAGetLastError() on windows instead of errno for some errors.
17 June 2008: Wouter
- outgoing num fds 32 by default on windows ; it supports less
fds for waiting on than unixes.

* first check for SOA record (negative answer) before NS record
and lameness.
* check if no AA bit for non-forwarder, and thus lame zone.
In response to error report by Richard Doty for mail.opusnet.com.
- fixup unput warning from lexer on freeBSD.
- bug#183. pidfile, rundir, and chroot configure options. Also the
example.conf and manual pages get the configured defaults.
You can use: (or accept the defaults to /usr/local/etc/unbound/)
--with-conf-file=filename
--with-pidfile=filename
--with-run-dir=path
--with-chroot-dir=path

--disable-static configure flag caused problems. (Patch from
Klaus Singvogel)
- bug 179: same fix as 177.
- bug 185: --disable-shared not passed along to ldns included with
unbound. Fixed so that configure parameters are passed to the
subdir configure script.
fixed that ./libtool is used always, you can still override
manually with ./configure libtool=mylibtool or set $libtool in
the environment.
- update of the ldns tarball to current ldns svn version (fix 181).
- bug 184: -r option for unbound-host, read resolv.conf for
forwarder. (Note that forwarder must support DNSSEC for validation
to succeed).

if that does not work, it will scale back its requirements.
27 March 2008: Wouter
- documented /dev/random symlink from chrootdir as FAQ entry.
26 March 2008: Wouter
- implemented AD bit signaling. If a query sets AD bit (but not DO)
then the AD bit is set in the reply if the answer validated.
Without including DNSSEC signatures. Useful if you have a trusted
path from the client to the resolver. Follows dnssec-updates draft.
25 March 2008: Wouter
- implemented check that for NXDOMAIN and NOERROR answers a query
section must be present in the reply (by the scrubber). And it must
be equal to the question sent, at least lowercase folded.
Previously this feature happened because the cache code refused
to store such messages. However blocking by the scrubber makes
sure nothing gets into the RRset cache. Also, this looks like a
timeout (instead of an allocation failure) and this retries are
done (which is useful in a spoofing situation).
- RTT banding. Band size 400 msec, this makes band around zero (fast)
include unknown servers. This makes unbound explore unknown servers.
7 March 2008: Wouter
- -C config feature for harvest program.
- harvest handles CNAMEs too.
5 March 2008: Wouter
- patch from Hugo Koji Kobayashi for iterator logs spelling.
4 March 2008: Wouter
- From report by Jinmei Tatuya, rfc2181 trust value for remainder
of a cname trust chain is lower; not full answer_AA.
- test for this fix.
- default config file location is /usr/local/etc/unbound.
Thus prefix is used to determine the location. This is also the
chroot and pidfile default location.
3 March 2008: Wouter
- Create 0.10 svn tag.
- 0.11 version in trunk.
- indentation nicer.
29 February 2008: Wouter
- documentation update.
- fixup port to Solaris of perf test tool.
- updated ldns-tarball with decl-after-statement fixes.
28 February 2008: Wouter

- option to use caps for id randomness.
- config file option use-caps-for-id: yes
- harvest debug tool
26 February 2008: Wouter
- delay utility delays TCP as well. If the server that is forwarded
to has a TCP error, the delay utility closes the connection.
- delay does REUSE_ADDR, and can handle a server that closes its end.
- answers use casing from query.
25 February 2008: Wouter
- delay utility works. Gets decent thoughput too (>20000).
22 February 2008: Wouter
- +2% for recursions, if identical queries (except for destination
and query ID) in the reply list, avoid re-encoding the answer.
- removed TODO items for optimizations that do not show up in
profile reports.
- default is now minievent - not libevent. As its faster and
not needed for regular installs, only for very large port ranges.
- loop check different speedup pkt-dname-reading, 1% faster for
nocache-recursion check.
- less hashing during msg parse, 4% for recursion.
- small speed fix for dname_count_size_labels, +1 or +2% recursion.
- some speed results noted:
optimization resulted in +40% for recursion (cache miss) and
+70 to +80 for cache hits, and +96% for version.bind.
zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
So, unbound can be about equal qps to NSD in cache hits.
And about 3.4x faster than BIND in cache performance.
- delay utility for testing.
21 February 2008: Wouter
- speedup of root-delegation message encoding by 15%.
- minor speedup of compress tree_lookup, maybe 1%.
- speedup of dname_lab_cmp and memlowercmp - the top functions in
profiler output, maybe a couple percent when it matters.
20 February 2008: Wouter
- setup speec_cache for need-ldns-testns in dotests.
- check number of queued replies on incoming queries to avoid overload
on that account.
- fptr whitelist checks are not disabled in optimize mode.
- do-daemonize config file option.
- minievent time share initializes time at start.
- updated testdata for nsec3 new algorithm numbers (6, 7).
- small performance test of packet encoding (root delegation).
19 February 2008: Wouter
- applied patch to unbound-host man page from Jan-Piet Mens.
- fix donotquery-localhost: yes default (it erroneously was switched
to default 'no').
- time is only gotten once and the value is shared across unbound.
- unittest cleans up crypto, so that it has no memory leaks.
- mini_event shares the time value with unbound this results in
+3% speed for cache responses and +9% for recursions.
- ldns tarball update with new NSEC3 sign code numbers.
- perform several reads per UDP operation. This improves performance
in DoS conditions, and costs very little in normal conditions.
improves cache response +50%, and recursions +10%.
- modified asynclook test. because the callback from async is not
in any sort of lock (and thus can use all library functions freely),
this causes a tiny race condition window when the last lock is
released for a callback and a new cancel() for that callback.
The only way to remove this is by putting callbacks into some
lock window. I'd rather have the small possibility of a callback
for a cancelled function then no use of library functions in
callbacks. Could be possible to only outlaw process(), wait(),
cancel() from callbacks, by adding another lock, but I'd rather not.
18 February 2008: Wouter
- patch to unbound-host from Jan-Piet Mens.
- unbound host prints errors if fails to configure context.
- fixup perf to resend faster, so that long waiting requests do
not hold up the queue, they become lost packets or SERVFAILs,
or can be sent a little while later (i.e. processing time may
take long, but throughput has to be high).
- fixup iterator operating in no cache conditions (RD flag unset
after a CNAME).
- streamlined code for RD flag setting.
- profiled code and changed dname compares to be faster.
The speedup is about +3% to +8% (depending on the test).
- minievent tests for eintr and eagain.
15 February 2008: Wouter
- added FreeBSD rc.d script to contrib.
- --prefix option for configure also changes directory: pidfile:
and chroot: defaults in config file.
- added cache speed test, for cache size OK and cache too small.

- test for statistics option
- ignore errors making directories, these can occur in parallel builds
- fixup Makefile strip command and libunbound docs typo.
31 January 2008: Wouter
- bg thread/process reads and writes the pipe nonblocking all the time
so that even if the pipe is buffered or so, the bg thread does not
block, and services both pipes and queries.

- check trailing / on chrootdir in checkconf.
- check if root hints and anchor files are in chrootdir.
- no route to host tcp error is verbosity level 2.

from netevent; the basic socket errors.
28 January 2008: Wouter

local_zone answers.
- fixup uninit warning from random.c; also seems to fix sporadic
sigFPE coming out of openssl.
- made openssl entropy warning more silent for library use. Needs
verbosity 1 now.
- fixup forgotten locks for rbtree_searches on ctx->query tree.
- random generator cleanup - RND_STATE_SIZE removed, and instead
a super-rnd can be passed at init to chain init random states.
- test also does lock checks if available.
- protect config access in libworker_setup().
- libevent doesn't like comm_base_exit outside of runloop.

- cancelation is threadsafe.
- asynclook extended test in tpkg.
- fixed two races where forked bg process waits for (somehow shared?)
locks, so does not service the query pipe on the bg side.
Now those locks are only held for fg_threads and for bg_as_a_thread.
24 January 2008: Wouter
- tested the cancel() function.
- asynclook -c (cancel) feature.
- fix fail to allocate context actions.

23 January 2008: Wouter
- removed debug prints from if-auto, verb-algo enables some.
- libunbound QUIT setup, remove memory leaks, when using threads
will share memory for passing results instead of writing it over
the pipe, only writes ID number over the pipe (towards the handler
thread that does process() ).
22 January 2008: Wouter
- library code for async in libunbound/unbound.c.
- fix link testbound.
- fixup exit bug in mini_event.

16 January 2008: Wouter
- incoming queries to the server with TC bit on are replied FORMERR.
- interface-automatic replied the wrong source address on localhost
queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
to use ifnum=-1 to mean 'no interface, use kernel route'.
15 January 2008: Wouter
- interface-automatic feature. experimental. Nice for anycast.
- tpkg test for ip6 ancillary data.
- removed debug prints.

with debugging (why do I get this answer).
- fixup CNAME handling, on nodata, sets and display canonname.
- dot removed from CNAME display.

- more API setup.
29 November 2007: Wouter
- 0.9 public API start.
28 November 2007: Wouter
- Changeup plan for 0.8 - no complication needed, a simple solution
has been chosen for authoritative features.
- you can use single quotes in the config file, so it is possible
to specify TXT records in local data.
- fixup small memory problem in implicit transparent zone creation.
- test for implicit zone creation and multiple RR RRsets local data.
- local-zone nodefault test.
- show testbound testlist on commit.

the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
domain exists).
- nicer verbosity: 0 and 1 levels.
- lower nonRDquery chance of eliciting wrongly typed validation
requiring message from the cache.
- fix for nonRDquery validation typing; nodata is detected when
SOA record in auth section (all validation-requiring nodata messages
have a SOA record in authority, so this is OK for the validator),
and NS record is needed to be a referral.
- duplicate checking when adding NSECs for a CNAME, and test.
- created svn tag 0.8, after completing testbed tests.
27 November 2007: Wouter
- per suggestion in rfc2308, replaced default max-ttl value with 1 day.
- set size of msgparse lookup table to 32, from 1024, so that its size
is below the 2048 regional large size threshold, and does not cause
a call to malloc when a message is parsed.
- update of memstats tool to print number of allocation calls.
This is what is taking time (not space) and indicates the avg size
of the allocations as well. region_alloc stat is removed.
22 November 2007: Wouter
- noted EDNS in-the-middle dropping trouble as a TODO.
At this point theoretical, no user trouble has been reported.
- added all default AS112 zones.
- answers from local zone content.
* positive answer, the rrset in question
* nodata answer (exist, but not that type).
* nxdomain answer (domain does not exist).
* empty-nonterminal answer.
* But not: wildcard, nsec, referral, rrsig, cname/dname,
or additional section processing, NS put in auth.
- test for correct working of static and transparent and couple
of important defaults (localhost, as112, reverses).
Also checks deny and refuse settings.
- fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
21 November 2007: Wouter
- local zone internal data setup.
20 November 2007: Wouter
- 0.8 - str2list config support for double string config options.
- local-zone and local-data options, config storage and documentation.
19 November 2007: Wouter
- do not downcase NSEC and RRSIG for verification. Follows
draft-ietf-dnsext-dnssec-bis-updates-06.txt.
- fixup leaking unbound daemons at end of tests.
- README file updated.
- nice libevent not found error.
- README talks about gnu make.
- 0.8: unit test for addr_mask and fixups for it.
and unit test for addr_in_common().
- 0.8: access-control config file element.
and unit test rpl replay file.
- 0.8: fixup address reporting from netevent.
16 November 2007: Wouter
- privilege separation is not needed in unbound at this time.
TODO item marked as such.
- created beta-0.7 branch for support.
- tagged 0.7 for beta release.
- moved trunk to 0.8 for 0.8(auth features) development.
- 0.8: access control list setup.
15 November 2007: Wouter
- review fixups from Jelte.
14 November 2007: Wouter
- testbed script does not recreate configure, since its in svn now.
- fixup checkconf test so that it does not test
/etc/unbound/unbound.conf.
- tag 0.6.
13 November 2007: Wouter
- remove debug print.
- fixup testbound exit when LIBEVENT_SIGNAL_PROBLEM exists.
12 November 2007: Wouter
- fixup signal handling where SIGTERM could be ignored if a SIGHUP
arrives later on.
- bugreports to unbound-bugs@nlnetlabs.nl
- fixup testbound so it exits cleanly.
- cleanup the caches on a reload, so that rrsetID numbers won't clash.
9 November 2007: Wouter
- took ldns snapshot in repo.
- default config file is /etc/unbound/unbound.conf.
If it doesn't exist, it is installed with the doc/example.conf file.
The file is not deleted on uninstall.
- default listening is not all, but localhost interfaces.
8 November 2007: Wouter
- Fixup chroot and drop user privileges.
- new L root ip address in default hints.
1 November 2007: Wouter
- Fixup of crash on reload, due to anchors in env not NULLed after
dealloc during deinit.
- Fixup of chroot call. Happens after privileges are dropped, so
that checking the passwd entry still works.
- minor touch up of clear() hashtable function.
- VERB_DETAIL prints out what chdir, username, chroot is being done.
- when id numbers run out, caches are cleared, as in design notes.
Tested with a mock setup with very few bits in id, it worked.
- harden-dnssec-stripped: yes is now default. It insists on dnssec
data for trust anchors. Included tests for the feature.
31 October 2007: Wouter
- cache-max-ttl config option.
- building outside sourcedir works again.
- defaults more secure:
username: "unbound"
chroot: "/etc/unbound"
The operator can override them to be less secure ("") if necessary.
- fix horrible oversight in sorting rrset references in a message,
sort per reference key pointer, not on referencepointer itself.
- pidfile: "/etc/unbound/unbound.pid" is now the default.
- tests changed to reflect the updated default.
- created hashtable clear() function that respects locks.
30 October 2007: Wouter
- fixup assertion failure that relied on compressed names to be
smaller than uncompressed names. A packet from comrite.com was seen
to be compressed to a larger size. Added it as unit test.
- quieter logging at low verbosity level for common tcp messages.
- no greedy TTL update.
23 October 2007: Wouter
- fixup (grand-)parent problem for dnssec-lameness detection.
- fixup tests to do additional section processing for lame replies,
since the detection needs that.
- no longer trust in query section in reply during dnssec lame detect.
- dnssec lameness does not make the server never ever queried, but
non-preferred. If no other servers exist or answer, the dnssec lame
server is used; the fastest dnssec lame server is chosen.
- added test then when trust anchor cannot be primed (nodata), the
insecure mode from unbound works.
- Fixup max queries per thread, any more are dropped.
22 October 2007: Wouter
- added donotquerylocalhost config option. Can be turned off for
out test cases.
- ISO C compat changes.
- detect RA-no-AA lameness, as LAME.
- DNSSEC-lameness detection, as LAME.
See notes in requirements.txt for choices made.
- tests for lameness detection.
- added all to make test target; need unbound for fwd tests.
- testbound does not pollute /etc/unbound.
19 October 2007: Wouter
- added configure (and its files) to svn, so that the trunk is easier
to use. ./configure, config.guess, config.sub, ltmain.sh,
and config.h.in.
- added yacc/lex generated files, util/configlexer.c,
util/configparser.c util/configparser.h, to svn.
- without lex no attempt to use it.
- unsecure response validation collated into one block.
- remove warning about const cast of cfgfile name.
- outgoing-interfaces can be different from service interfaces.
- ldns-src configure is done during unbound configure and
ldns-src make is done during unbound make, and so inherits the
make arguments from the unbound make invocation.
- nicer error when libevent problem causes instant exit on signal.
- read root hints from a root hint file (like BIND does).
18 October 2007: Wouter
- addresses are logged with errors.
- fixup testcode fake event to remove pending before callback
since the callback may create new pending items.
- tests updated because retries are now in iterator module.
- ldns-testpkts code is checked for differences between unbound
and ldns by makedist.sh.
- ldns trunk from today added in svn repo for fallback in case
no ldns is installed on the system.
make download_ldns refreshes the tarball with ldns svn trunk.
- ldns-src.tar.gz is used if no ldns is found on the system, and
statically linked into unbound.
- start of regional allocator code.
- regional uses less memory and variables, simplified code.
- remove of region-allocator.
- alloc cache keeps a cache of recently released regional blocks,
up to a maximum.
- make unit test cleanly free memory.
17 October 2007: Wouter
- fixup another cycle detect and ns-addr timeout resolution bug.
This time by refusing delegations from the cache without addresses
when resolving a mandatory-glue nameserver-address for that zone.
We're going to have to ask a TLD server anyway; might as well be
the TLD server for this name. And this resolves a lot of cases where
the other nameserver names lead to cycles or are not available.
- changed random generator from random(3) clone to arc4random wrapped
for thread safety. The random generator is initialised with
entropy from the system.
- fix crash where failure to prime DNSKEY tried to print null pointer
in the log message.
- removed some debug prints, only verb_algo (4) enables them.
- fixup test; new random generator took new paths; such as one
where no scripted answer was available.
- mark insecure RRs as insecure.
- fixup removal of nonsecure items from the additional.
- reduced timeout values to more realistic, 376 msec (262 msec has
90% of roundtrip times, 512 msec has 99% of roundtrip times.)
- server selection failover to next server after timeout (376 msec).
16 October 2007: Wouter
- no malloc in log_hex.
- assertions around system calls.
- protect against gethostname without ending zero.
- ntop output is null terminated by unbound.
- pidfile content null termination
- various snprintf use sizeof(stringbuf) instead of fixed constant.
- changed loopdetect % 8 with & 0x7 since % can become negative for
weird negative input and particular interpretation of integer math.
- dname_pkt_copy checks length of result, to protect result buffers.
prints an error, this should not happen. Bad strings should have
been rejected earlier in the program.
- remove a size_t underflow from msgreply size func.
15 October 2007: Wouter
- nicer warning.
- fix IP6 TCP, wrong definition check. With test package.
- fixup the fact that the query section was not compressed to,
the code was there but was called by value instead of by reference.
And test for the case, uses xxd and nc.
- more portable ip6 check for sockaddr types.
8 October 2007: Wouter
- --disable-rpath option in configure for 64bit systems with
several dynamic lib dirs.
7 October 2007: Wouter
- fixup tests for no AD bit in non-DO queries.
- test that makes sure AD bit is not set on non-DO query.
6 October 2007: Wouter
- removed logfile open early. It did not have the proper permissions;
it was opened as root instead of the user. And we cannot change user
id yet, since chroot and bind ports need to be done.
- callback checks for event callbacks done from mini_event. Because
of deletions cannot do this from netevent. This means when using
libevent the protection does not work on event-callbacks.
- fixup too small reply (did not zero counts).
- fixup reply no longer AD bit when query without DO bit.
5 October 2007: Wouter
- function pointer whitelist.
4 October 2007: Wouter
- overwrite sensitive random seed value after use.
- switch to logfile very soon if not -d (console attached).
- error messages do not reveal the trustanchor contents.
- start work on function pointer whitelists.
3 October 2007: Wouter
- fix for multiple empty nonterminals, after multiple DSes in the
chain of trust.
- mesh checks if modules are looping, and stops them.
- refetch with CNAMEd nameserver address regression test added.
- fixup line count bug in testcode, so testbound prints correct line
number with parse errors.
- unit test for multiple ENT case.
- fix for cname out of validated unsec zone.
- fixup nasty id=0 reuse. Also added assertions to detect its
return (the assertion catches in the existing test cases).
1 October 2007: Wouter
- skip F77, CXX, objC tests in configure step.
- fixup crash in refetch glue after a CNAME.
and protection against similar failures (with error print).
28 September 2007: Wouter
- test case for unbound-checkconf, fixed so it also checks the
interface: statements.
26 September 2007: Wouter
- SIGHUP will reopen the log file.
- Option to log to syslog.
- please lint, fixup tests (that went to syslog on open, oops).
- config check program.
25 September 2007: Wouter
- tests for NSEC3. Fixup bitmap checks for NSEC3.
- positive ANY response needs to check if wildcard expansion, and
check that original data did not exist.
- tests for NSEC3 that wrong use of OPTOUT is bad. For insecure
delegation, for abuse of child zone apex nsec3.
- create 0.5 release tag.
24 September 2007: Wouter
- do not make test programs by default.
- But 'make test' will perform all of the tests.
- Advertise builtin select libevent alternative when no libevent
is found.
- signit can generate NSEC3 hashes, for generating tests.
- multiple nsec3 parameters in message test.
- too high nsec3 iterations becomes insecure test.
21 September 2007: Wouter
- fixup empty_DS_name allocated in wrong region (port DEC Alpha).
- fixup testcode lock safety (port FreeBSD).
- removes subscript has type char warnings (port Solaris 9).
- fixup of field with format type to int (port MacOS/X intel).
- added test for infinite loop case in nonRD answer validation.
It was a more general problem, but hard to reproduce. When an
unsigned rrset is being validated and the key fetched, the DS
sequence is followed, but if the final name has no DS, then no
proof is possible - the signature has been stripped off.
20 September 2007: Wouter
- fixup and test for NSEC wildcard with empty nonterminals.
- makedist.sh fixup for svn info.
- acl features request in plan.
- improved DS empty nonterminal handling.
- compat with ANS nxdomain for empty nonterminals. Attempts the nodata
proof anyway, which succeeds in ANS failure case.
- striplab protection in case it becomes -1.
- plans for static and blacklist config.
19 September 2007: Wouter
- comments about non-packed usage.
- plan for overload support in 0.6.
- added testbound tests for a failed resolution from the logs
and for failed prime when missing glue.
- fixup so useless delegation points are not returned from the
cache. Also the safety belt is used if priming fails to complete.
- fixup NSEC rdata not to be lowercased, bind compat.
18 September 2007: Wouter
- wildcard nsec3 testcases, and fixup to get correct wildcard name.
- validator prints subtype classification for debug.
17 September 2007: Wouter
- NSEC3 hash cache unit test.
- validator nsec3 nameerror test.
14 September 2007: Wouter
- nsec3 nodata proof, nods proof, wildcard proof.
- nsec3 support for cname chain ending in noerror or nodata.
- validator calls nsec3 proof routines if no NSECs prove anything.
- fixup iterator bug where it stored the answer to a cname under
the wrong qname into the cache. When prepending the cnames, the
qname has to be reset to the original qname.
13 September 2007: Wouter
- nsec3 find matching and covering, ce proof, prove namerror msg.
12 September 2007: Wouter
- fixup of manual page warnings, like for NSD bugreport.
- nsec3 work, config, max iterations, filter, and hash cache.
6 September 2007: Wouter
- fixup to find libevent on mac port install.
- fixup size_t vs unsigned portability in validator/sigcrypt.
- please compiler on different platforms, for unreachable code.
- val_nsec3 file.
- pthread_rwlock type is optional, in case of old pthread libs.
5 September 2007: Wouter
- cname, name error validator tests.
- logging of qtype ANY works.
- ANY type answers get RRSIG in answer section of replies (but not
in other sections, unless DO bit is on).
- testbound can replay a TCP query (set MATCH TCP in the QUERY).
- DS and noDS referral validation test.
- if you configure many trust anchors, parent trust anchors can
securely deny existence of child trust anchors, if validated.
- not all *.name NSECs are present because a wildcard was matched,
and *.name NSECs can prove nodata for empty nonterminals.
Also, for wildcard name NSECs, check they are not from the parent
zone (for wildcarded zone cuts), and check absence of CNAME bit,
for a nodata proof.
- configure option for memory allocation debugging.
- port configure option for memory allocation to solaris10.
4 September 2007: Wouter
- fixup of Leakage warning when serviced queries processed multiple
callbacks for the same query from the same server.
- testbound removes config file from /tmp on failed exit.
- fixup for referral cleanup of the additional section.
- tests for cname, referral validation.
- neater testbound tpkg output.
- DNAMEs no longer match their apex when synthesized from the cache.
- find correct signer name for DNAME responses.
- wildcarded DNAME test and fixup code to detect.
- prepend NSEC and NSEC3 rrsets in the iterator while chasing CNAMEs.
So that wildcarded CNAMEs get their NSEC with them to the answer.
- test for a CNAME to a DNAME to a CNAME to an answer, all from
different domains, for key fetching and signature checking of
CNAME'd messages.
3 September 2007: Wouter
- Fixed error in iterator that would cause assertion failure in
validator. CNAME to a NXDOMAIN response was collated into a response
with both a CNAME and the NXDOMAIN rcode. Added a test that the
rcode is changed to NOERROR (because of the CNAME).
- timeout on tcp does not lead to spurious leakage detect.
- account memory for name of lame zones, so that memory leakages does
not show lame cache growth as a leakage growth.
- config setting for lameness cache expressed in bytes, instead of
number of entries.
- tool too summarize allocations per code line.
31 August 2007: Wouter
- can read bind trusted-keys { ... }; files, in a compatibility mode.
- iterator should not detach target queries that it still could need.
the protection against multiple outstanding queries is moved to a
current_query num check.
- validator nodata, positive, referral tests.
- dname print can print '*' wildcard.
30 August 2007: Wouter
- fixup override date config option.
- config options to control memory usage.
- caught bad free of un-alloced data in worker_send error case.
- memory accounting for key cache (trust anchors and temporary cache).
- memory accounting fixup for outside network tcp pending waits.
- memory accounting fixup for outside network tcp callbacks.
- memory accounting for iterator fixed storage.
- key cache size and slabs config options.
- lib crypto cleanups at exit.
29 August 2007: Wouter
- test tool to sign rrsets for testing validator with.
- added RSA and DSA test keys, public and private pairs, 512 bits.
- default configuration is with validation enabled.
Only a trust-anchor needs to be configured for DNSSEC to work.
- do not convert to DER for DSA signature verification.
- validator replay test file, for a DS to DNSKEY DSA key prime and
positive response.
28 August 2007: Wouter
- removed double use for udp buffers, that could fail,
instead performs a malloc to do the backup.
- validator validates referral messages, by validating all the rrsets
and stores the rrsets in the cache. Further referral (nonRD queries)
replies are made from the rrset cache directly. Unless unchecked
rrsets are encountered, there are then validated.
- enforce that signing is done by a parent domain (or same domain).
- adjust TTL downwards if rrset TTL bigger than signature allows.
- permissive mode feature, sets AD bit for secure, but bogus does
not give servfail (bogus is changed into indeterminate).
- optimization of rrset verification. rr canonical sorting is reused,
for the same rrset. canonical rrset image in buffer is reused for
the same signature.
- if the rrset is too big (64k exactly + large owner name) the
canonicalization routine will fail if it does not fit in buffer.
- faster verification for large sigsets.
- verb_detail mode reports validation failures, but not the entire
algorithm for validation. Key prime failures are reported as
verb_ops level.
27 August 2007: Wouter
- do not garble the edns if a cache answer fails.
- answer norecursive from cache if possible.
- honor clean_additional setting when returning secure non-recursive
referrals.
- do not store referral in msg cache for nonRD queries.
- store verification status in the rrset cache to speed up future
verification.
- mark rrsets indeterminate and insecure if they are found to be so.
and store this in the cache.
24 August 2007: Wouter
- message is bogus if unsecure authority rrsets are present.
- val-clean-additional option, so you can turn it off.
- move rrset verification out of the specific proof types into one
routine. This makes the proof routines prettier.
- fixup cname handling in validator, cname-to-positive and cname-to-
nodata work.
- Do not synthesize DNSKEY and DS responses from the rrset cache if
the rrset is from the additional section. Signatures may have
fallen off the packet, and cause validation failure.
- more verbose signature date errors (with the date attached).
- increased default infrastructure cache size. It is important for
performance, and 1000 entries are only 212k (or a 400 k total cache
size). To 10000 entries (for 2M entries, 4M cache size).
23 August 2007: Wouter
- CNAME handling - move needs_validation to before val_new().
val_new() setups the chase-reply to be an edited copy of the msg.
new classification, and find signer can find for it.
removal of unsigned crap from additional, and query restart for
cname.
- refuse to follow wildcarded DNAMEs when validating.
But you can query for qtype ANY, or qtype DNAME and validate that.
22 August 2007: Wouter
- bogus TTL.
- review - use val_error().
21 August 2007: Wouter
- ANY response validation.
- store security status in cache.
- check cache security status and either send the query to be
validated, return the query to client, or send servfail to client.
Sets AD bit on validated replies.
- do not examine security status on an error reply in mesh_done.
- construct DS, DNSKEY messages from rrset cache.
- manual page entry for override-date.
20 August 2007: Wouter
- validate and positive validation, positive wildcard NSEC validation.
- nodata validation, nxdomain validation.
18 August 2007: Wouter
- process DNSKEY response in FINDKEY state.
17 August 2007: Wouter
- work on DS2KE routine.
- val_nsec.c for validator NSEC proofs.
- unit test for NSEC bitmap reading.
- dname iswild and canonical_compare with unit tests.
16 August 2007: Wouter
- DS sig unit test.
- latest release libevent 1.3c and 1.3d have threading fixed.
- key entry fixup data pointer and ttl absolute.
- This makes a key-prime succeed in validator, with DS or DNSKEY as
trust-anchor.
- fixup canonical compare byfield routine, fix bug and also neater.
- fixed iterator response type classification for queries of type
ANY and NS.
dig ANY gives sometimes NS rrset in AN and NS section, and parser
removes the NS section duplicate. dig NS gives sometimes the NS
in the answer section, as referral.
- validator FINDKEY state.
15 August 2007: Wouter
- crypto calls to verify signatures.
- unit test for rrsig verification.
14 August 2007: Wouter
- default outgoing ports changed to avoid port 2049 by default.
This port is widely blocked by firewalls.
- count infra lameness cache in memory size.
- accounting of memory improved
- outbound entries are allocated in the query region they are for.
- extensive debugging for memory allocations.
- --enable-lock-checks can be used to enable lock checking.
- protect undefs in config.h from autoheaders ministrations.
- print all received udp packets. log hex will print on multiple
lines if needed.
- fixed error in parser with backwards rrsig references.
- mark cycle targets for iterator did not have CD flag so failed
its task.
13 August 2007: Wouter
- fixup makefile, if lexer is missing give nice error and do not
mess up the dependencies.
- canonical compare routine updated.
- canonical hinfo compare.
- printout list of the queries that the mesh is working on.
10 August 2007: Wouter
- malloc and free overrides that track total allocation and frees.
for memory debugging.
- work on canonical sort.
9 August 2007: Wouter
- canonicalization, signature checks
- dname signature label count and unit test.
- added debug heap size print to memory printout.
- typo fixup in worker.c
- -R needed on solaris.
- validator override option for date check testing.
8 August 2007: Wouter
- ldns _raw routines created (in ldns trunk).
- sigcrypt DS digest routines
- val_utils uses sigcrypt to perform signature cryptography.
- sigcrypt keyset processing
7 August 2007: Wouter
- security status type.
- security status is copied when rdata is equal for rrsets.
- rrset id is updated to invalidate all the message cache entries
that refer to NSEC, NSEC3, DNAME rrsets that have changed.
- val_util work
- val_sigcrypt file for validator signature checks.
6 August 2007: Wouter
- key cache for validator.
- moved isroot and dellabel to own dname routines, with unit test.
3 August 2007: Wouter
- replanning.
- scrubber check section of lame NS set.
- trust anchors can be in config file or read from zone file,
DS and DNSKEY entries.
- unit test trust anchor storage.
- trust anchors converted to packed rrsets.
- key entry definition.
2 August 2007: Wouter
- configure change for latest libevent trunk version (needs -lrt).
- query_done and walk_supers are moved out of module interface.
- fixup delegation point duplicates.
- fixup iterator scrubber; lame NS set is let through the scrubber
so that the classification is lame.
- validator module exists, and does nothing but pass through,
with calling of next module and return.
- validator work.
1 August 2007: Wouter
- set version to 0.5
- module work for module to module interconnections.
- config of modules.
- detect cycle takes flags.
31 July 2007: Wouter
- updated plan
- release 0.4 tag.
30 July 2007: Wouter
- changed random state init, so that sequential process IDs are not
cancelled out by sequential thread-ids in the random number seed.
- the fwd_three test, which sends three queries to unbound, and
unbound is kept waiting by ldns-testns for 3 seconds, failed
because the retry timeout for default by unbound is 3 seconds too,
it would hit that timeout and fail the test. Changed so that unbound
is kept waiting for 2 seconds instead.
27 July 2007: Wouter
- removed useless -C debug option. It did not work.
- text edit of documentation.
- added doc/CREDITS file, referred to by the manpages.
- updated planning.
26 July 2007: Wouter
- cycle detection, for query state dependencies. Will attempt to
circumvent the cycle, but if no other targets available fails.
- unit test for AXFR, IXFR response.
- test for cycle detection.
25 July 2007: Wouter
- testbound read ADDRESS and check it.
- test for version.bind and friends.
- test for iterator chaining through several referrals.
- test and fixup for refetch for glue. Refetch fails if glue
is still not provided.
24 July 2007: Wouter
- Example section in config manual.
- Addr stored for range and moment in replay.
20 July 2007: Wouter
- Check CNAME chain before returning cache entry with CNAMEs.
- Option harden-glue, default is on. It will discard out of zone
data. If disabled, performance is faster, but spoofing attempts
become a possibility. Note that still normalize scrubbing is done,
and that the potentially spoofed data is used for infrastructure
and not returned to the client.
- if glue times out, refetch by asking parent of delegation again.
Much like asking for DS at the parent side.
- TODO items from forgery-resilience draft.
and on memory handling improvements.
- renamed module_event_timeout to module_event_noreply.
- memory reporting code; reports on memory usage after handling
a network packet (not on cache replies).
19 July 2007: Wouter
- shuffle NS selection when getting nameserver target addresses.
- fixup of deadlock warnings, yield cpu in checklock code so that
freebsd scheduler selects correct process to run.
- added identity and version config options and replies.
- store cname messages complete answers.
18 July 2007: Wouter
- do not query addresses, 127.0.0.1, and ::1 by default.
17 July 2007: Wouter
- forward zone options in config file.
- forward per zone in iterator. takes precedence over stubs.
- fixup commithooks.
- removed forward-to and forward-to-port features, subsumed by
new forward zones.
- fix parser to handle absent server: clause.
- change untrusted rrset test to account for scrubber that is now
applied during the test (which removes the poison, by the way).
- feature, addresses can be specified with @portnumber, like nsd.conf.
- test config files changed over to new forwarder syntax.
27 June 2007: Wouter
- delete of mesh does a postorder traverse of the tree.
- found and fixed a memory leak. For TTL=0 messages, that would
not be cached, instead the msg-replyinfo structure was leaked.
- changed server selection so it will filter out hosts that are
unresponsive. This is defined as a host with the maximum rto value.
This means that unbound tried the host for retries up to 120 secs.
The rto value will time out after host-ttl seconds from the cache.
This keeps such unresolvable queries from taking up resources.
- utility for keeping histogram.
26 June 2007: Wouter
- mesh is called by worker, and iterator uses it.
This removes the hierarchical code.
QueryTargets state and Finished state are merged for iterator.
- forwarder mode no longer sets AA bit on first reply.
- rcode in walk_supers is not needed.
25 June 2007: Wouter
- more mesh work.
- error encode routine for ease.
22 June 2007: Wouter
- removed unused _node iterator value from rbtree_t. Takes up space.
- iterator can handle querytargets state without a delegation point
set, so that a priming(stub) subquery error can be handled.
- iterator stores if it is priming or not.
- log_query_info() neater logging.
- changed iterator so that it does not alter module_qstate.qinfo
but keeps a chase query info. Also query_flags are not altered,
the iterator uses chase_flags.
- fixup crash in case no ports for the family exist.
21 June 2007: Wouter
- Fixup secondary buffer in case of error callback.
- cleanup slumber list of runnable states.

- another offbyone in targetcounter. Also in Java prototype by the way.
15 June 2007: Wouter
- if a query asks to be notified of the same serviced query result
multiple times, this will succeed. Only one callback will happen;
multiple outbound-list entries result (but the double cleanup of it
will not matter).
- when iterator moves on due to CNAME or referral, it will remove
the subqueries (for other targets). These are put on the slumber
list.
- state module wait subq is OK with no new subqs, an old one may have
stopped, with an error, and it is still waiting for other ones.
- if a query loops, halt entire query (easy way to clean up properly).
14 June 2007: Wouter
- num query targets was > 0 , not >= 0 compared, so that fetch
policy of 0 did nothing.

- doxygen 1.5 fixes for comments (for the strict check on docs).
11 June 2007: Wouter
- replies on TCP queries have the address field set in replyinfo,
for serviced queries, because the initiator does not know that
a TCP fallback has occured.
- omit DNSSEC types from nonDO replies, except if qtype is ANY or
if qtype directly queries for the type (and then only show that
'unknown type' in the answer section).
- fixed message parsing where rrsigs on their own would be put
in the signature list over the rrsig type.
