%description

The Knot DNS Resolver is a caching full resolver implementation written in C

and LuaJIT, including both a resolver library and a daemon. Modular

architecture of the library keeps the core tiny and efficient, and provides

a state-machine like API for extensions.

The package is pre-configured as local caching resolver.

To start using it, just start the local DNS socket:

# systemctl start kresd.socket

BEWARE:

Because of https://bugzilla.redhat.com/show_bug.cgi?id=1366968

you need to switch your system to SELinux permissive mode.

* Tue Jan 23 2018 Tomas Krizek <tomas.krizek@nic.cz> - 1.5.3-1

- New upstream release 1.5.3

Knot Resolver 1.5.3 (2018-01-23)

================================

Bugfixes

--------

- fix the hints module on some systems, e.g. Fedora.

  Symptom: `undefined symbol: engine_hint_root_file`

Knot Resolver 1.5.2 (2018-01-22)

================================

Security

--------

- fix CVE-2018-1000002: insufficient DNSSEC validation, allowing

  attackers to deny existence of some data by forging packets.

  Some combinations pointed out in RFC 6840 sections 4.1 and 4.3

  were not taken into account.

Bugfixes

--------

- memcached: fix fallout from module rename in 1.5.1

Knot Resolver 1.5.1 (2017-12-12)

================================

Incompatible changes

--------------------

- script supervisor.py was removed, please migrate to a real process manager

- module ketcd was renamed to etcd for consistency

- module kmemcached was renamed to memcached for consistency

Bugfixes

--------

- fix SIGPIPE crashes (#271)

- tests: work around out-of-space for platforms with larger memory pages

- lua: fix mistakes in bindings affecting 1.4.0 and 1.5.0 (and 1.99.1-alpha),

  potentially causing problems in dns64 and workarounds modules

- predict module: various fixes (!399)

Improvements

------------

- add priming module to implement RFC 8109, enabled by default (#220)

- add modules helping with system time problems, enabled by default;

  for details see documentation of detect_time_skew and detect_time_jump

* Fri Jan 05 2018 Tomas Krizek <tomas.krizek@nic.cz> - 1.5.0-2

- add doc package

- configure tarball signature verification

- add root.hints file

* Mon Nov 06 2017 Petr Špaček <petr.spacek@nic.cz> - 1.5.0-1

- New upstream release 1.5.0

Knot Resolver 1.5.0 (2017-11-02)

================================

Bugfixes

--------

- fix loading modules on Darwin

Improvements

------------

- new module ta_signal_query supporting Signaling Trust Anchor Knowledge

  using Keytag Query (RFC 8145 section 5); it is enabled by default

- attempt validation for more records but require it for fewer of them

  (e.g. avoids SERVFAIL when server adds extra records but omits RRSIGs)

Knot Resolver 1.4.0 (2017-09-22)

================================

Incompatible changes

--------------------

- lua: query flag-sets are no longer represented as plain integers.

  kres.query.* no longer works, and kr_query_t lost trivial methods

  'hasflag' and 'resolved'.

  You can instead write code like qry.flags.NO_0X20 = true.

Bugfixes

--------

- fix exiting one of multiple forks (#150)

- cache: change the way of using LMDB transactions.  That in particular

  fixes some cases of using too much space with multiple kresd forks (#240).

Improvements

------------

- policy.suffix: update the aho-corasick code (#200)

- root hints are now loaded from a zonefile; exposed as hints.root_file().

  You can override the path by defining ROOTHINTS during compilation.

- policy.FORWARD: work around resolvers adding unsigned NS records (#248)

- reduce unneeded records previously put into authority in wildcarded answers

Knot Resolver 1.3.3 (2017-08-09)

================================

Security

--------

- Fix a critical DNSSEC flaw.  Signatures might be accepted as valid

  even if the signed data was not in bailiwick of the DNSKEY used to

  sign it, assuming the trust chain to that DNSKEY was valid.

Bugfixes

--------

- iterate: skip RRSIGs with bad label count instead of immediate SERVFAIL

- utils: fix possible incorrect seeding of the random generator

- modules/http: fix compatibility with the Prometheus text format

Improvements

------------

- policy: implement remaining special-use domain names from RFC6761 (#205),

  and make these rules apply only if no other non-chain rule applies

* Tue Aug 01 2017 Petr Spacek <petr.spacek@nic.cz> - 1.3.2-1

New upstream release:

Knot Resolver 1.3.2 (2017-07-28)

================================

Security

--------

- fix possible opportunities to use insecure data from cache as keys

  for validation

Bugfixes

--------

- daemon: check existence of config file even if rundir isn't specified

- policy.FORWARD and STUB: use RTT tracking to choose servers (#125, #208)

- dns64: fix CNAME problems (#203)  It still won't work with policy.STUB.

- hints: better interpretation of hosts-like files (#204)

         also, error out if a bad entry is encountered in the file

- dnssec: handle unknown DNSKEY/DS algorithms (#210)

- predict: fix the module, broken since 1.2.0 (#154)

Improvements

------------

- embedded LMDB fallback: update 0.9.18 -> 0.9.21

* Wed Jul 26 2017 Fedora Release Engineering <releng@fedoraproject.org> - 1.3.1-1.1

- Rebuilt for https://fedoraproject.org/wiki/Fedora_27_Mass_Rebuild

* Tue Jul 11 2017 Petr Spacek <petr.spacek@nic.cz> - 1.3.1-2

- build experimental command line interface "kresc"

* Tue Jul 11 2017 Petr Spacek <petr.spacek@nic.cz> - 1.3.1-1

New upstream release:

Knot Resolver 1.3.1 (2017-06-23)

================================

Bugfixes

--------

- modules/http: fix finding the static files (bug from 1.3.0)

- policy.FORWARD: fix some cases of CNAMEs obstructing search for zone cuts

Knot Resolver 1.3.0 (2017-06-13)

================================

Security

--------

- Refactor handling of AD flag and security status of resource records.

  In some cases it was possible for secure domains to get cached as

  insecure, even for a TLD, leading to disabled validation.

  It also fixes answering with non-authoritative data about nameservers.

Improvements

------------

- major feature: support for forwarding with validation (#112).

  The old policy.FORWARD action now does that; the previous non-validating

  mode is still avaliable as policy.STUB except that also uses caching (#122).

- command line: specify ports via @ but still support # for compatibility

- policy: recognize 100.64.0.0/10 as local addresses

- layer/iterate: *do* retry repeatedly if REFUSED, as we can't yet easily

  retry with other NSs while avoiding retrying with those who REFUSED

- modules: allow changing the directory where modules are found,

  and do not search the default library path anymore.

Bugfixes

--------

- validate: fix insufficient caching for some cases (relatively rare)

- avoid putting "duplicate" record-sets into the answer (#198)

Knot Resolver 1.2.6 (2017-04-24)

================================

Security

--------

- dnssec: don't set AD flag for NODATA answers if wildcard non-existence

  is not guaranteed due to opt-out in NSEC3

Improvements

------------

- layer/iterate: don't retry repeatedly if REFUSED

Bugfixes

--------

- lib/nsrep: revert some changes to NS reputation tracking that caused

  severe problems to some users of 1.2.5 (#178 and #179)

- dnssec: fix verification of wildcarded non-singleton RRsets

- dnssec: allow wildcards located directly under the root

- layer/rrcache: avoid putting answer records into queries in some cases

* Thu Apr 06 2017 Petr Spacek <petr.spacek@nic.cz> - 1.2.5-1

- new upstream release

 + security: Knot Resolver 1.2.0 and higher could return AD flag for insecure

* Mon Feb 27 2017 Petr Spacek <petr.spacek@nic.cz> - 1.2.3-1
