%description

The Knot Resolver is a DNSSEC-enabled 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, start a single kresd instance:

$ systemctl start kresd@1.service

Knot Resolver 3.2.1 (2019-01-10)

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

Bugfixes

--------

- trust_anchors: respect validity time range during TA bootstrap (!748)

- fix TLS rehandshake handling (!739)

- make TLS_FORWARD compatible with GnuTLS 3.3 (!741)

- special thanks to Grigorii Demidov for his long-term work on Knot Resolver!

Improvements

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

- improve handling of timeouted outgoing TCP connections (!734)

- trust_anchors: check syntax of public keys in DNSKEY RRs (!748)

- validator: clarify message about bogus non-authoritative data (!735)

- dnssec validation failures contain more verbose reasoning (!735)

- new function trust_anchors.summary() describes state of DNSSEC TAs (!737),

  and logs new state of trust anchors after start up and automatic changes

- trust anchors: refuse revoked DNSKEY even if specified explicitly,

  and downgrade missing the SEP bit to a warning

* Mon Dec 17 2018 Tomas Krizek <tomas.krizek@nic.cz> - 3.2.0-1

Knot Resolver 3.2.0 (2018-12-17)

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

New features

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

- module edns_keepalive to implement server side of RFC 7828 (#408)

- module nsid to implement server side of RFC 5001 (#289)

- module bogus_log provides .frequent() table (!629, credit Ulrich Wisser)

- module stats collects flags from answer messages (!629, credit Ulrich Wisser)

- module view supports multiple rules with identical address/TSIG specification

  and keeps trying rules until a "non-chain" action is executed (!678)

- module experimental_dot_auth implements an DNS-over-TLS to auth protocol

  (!711, credit Manu Bretelle)

- net.bpf bindings allow advanced users to use eBPF socket filters

Bugfixes

--------

- http module: only run prometheus in parent process if using --forks=N,

  as the submodule collects metrics from all sub-processes as well.

- TLS fixes for corner cases (!700, !714, !716, !721, !728)

- fix build with -DNOVERBOSELOG (#424)

- policy.{FORWARD,TLS_FORWARD,STUB}: respect net.ipv{4,6} setting (!710)

- avoid SERVFAILs due to certain kind of NS dependency cycles, again

  (#374) this time seen as 'circular dependency' in verbose logs

- policy and view modules do not overwrite result finished requests (!678)

Improvements

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

- Dockerfile: rework, basing on Debian instead of Alpine

- policy.{FORWARD,TLS_FORWARD,STUB}: give advantage to IPv6

  when choosing whom to ask, just as for iteration

- use pseudo-randomness from gnutls instead of internal ISAAC (#233)

- tune the way we deal with non-responsive servers (!716, !723)

- documentation clarifies interaction between policy and view modules (!678, !730)

Module API changes

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

- new layer is added: answer_finalize

- kr_request keeps ::qsource.packet beyond the begin layer

- kr_request::qsource.tcp renamed to ::qsource.flags.tcp

- kr_request::has_tls renamed to ::qsource.flags.tls

- kr_zonecut_add(), kr_zonecut_del() and kr_nsrep_sort() changed parameters slightly

* Fri Nov 02 2018 Tomas Krizek <tomas.krizek@nic.cz> - 3.1.0-1

Knot Resolver 3.1.0 (2018-11-02)

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

Incompatible changes

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

- hints.use_nodata(true) by default; that's what most users want

- libknot >= 2.7.2 is required

Improvements

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

- cache: handle out-of-space SIGBUS slightly better (#197)

- daemon: improve TCP timeout handling (!686)

Bugfixes

--------

- cache.clear('name'): fix some edge cases in API (#401)

- fix error handling from TLS writes (!669)

- avoid SERVFAILs due to certain kind of NS dependency cycles (#374)

* Mon Aug 20 2018 Tomas Krizek <tomas.krizek@nic.cz> - 3.0.0-1

Knot Resolver 3.0.0 (2018-08-20)

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

Incompatible changes

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

- cache: fail lua operations if cache isn't open yet (!639)

  By default cache is opened *after* reading the configuration,

  and older versions were silently ignoring cache operations.

  Valid configuration must open cache using `cache.open()` or `cache.size =`

  before executing cache operations like `cache.clear()`.

- libknot >= 2.7.1 is required, which brings also larger API changes

- in case you wrote custom Lua modules, please consult

  https://knot-resolver.readthedocs.io/en/latest/lib.html#incompatible-changes-since-3-0-0

- in case you wrote custom C modules, please see compile against

  Knot DNS 2.7 and adjust your module according to messages from C compiler

- DNS cookie module (RFC 7873) is not available in this release,

  it will be later reworked to reflect development in IEFT dnsop working group

- version module was permanently removed because it was not really used by users;

  if you want to receive notifications abou new releases please subscribe to

  https://lists.nic.cz/cgi-bin/mailman/listinfo/knot-resolver-announce

Bugfixes

--------

- fix multi-process race condition in trust anchor maintenance (!643)

- ta_sentinel: also consider static trust anchors not managed via RFC 5011

Improvements

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

- reorder_RR() implementation is brought back

- bring in performace improvements provided by libknot 2.7

- cache.clear() has a new, more powerful API

- cache documentation was improved

- old name "Knot DNS Resolver" is replaced by unambiguous "Knot Resolver"

  to prevent confusion with "Knot DNS" authoritative server

* Thu Aug 02 2018 Tomas Krizek <tomas.krizek@nic.cz> - 2.4.1-1

Knot Resolver 2.4.1 (2018-08-02)

- TLS_FORWARD policy uses system CA certificate store by default (!568)

- aggressive caching for NSEC3 zones (!600)

- optional protection from DNS Rebinding attack (module rebinding, !608)

- module bogus_log to log DNSSEC bogus queries without verbose logging (!613)

Bugfixes

--------

- prefill: fix ability to read certificate bundle (!578)

- avoid turning off qname minimization in some cases, e.g. co.uk. (#339)

- TLS: improve error handling and documentation (!536, !555, !559)

Improvements

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

- prefill: new module to periodically import root zone into cache

  (replacement for RFC 7706, !511)

- network_listen_fd: always create end point for supervisor supplied file descriptor

- use CPPFLAGS build environment variable if set (!547)

* Wed Mar 28 2018 Tomas Krizek <tomas.krizek@nic.cz> - 2.2.0-1

Knot Resolver 2.2.0 (2018-03-28)

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

* Fri Feb 16 2018 Tomas Krizek <tomas.krizek@nic.cz> - 2.1.0-1

- New upstream release 2.1.0

Knot Resolver 2.1.0 (2018-02-16)

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

Incompatible changes

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

- stats: remove tracking of expiring records (predict uses another way)

- systemd: more chages in default unit files (TODO)

- ta_sentinel: implement protocol draft-ietf-dnsop-kskroll-sentinel-01

  (our draft-ietf-dnsop-kskroll-sentinel-00 implementation had inverted logic)

- libknot: require version 2.6.4 or newer to get bugfixes for DNS-over-TLS

Bugfixes

--------

- detect_time_jump module: don't clear cache on suspend-resume (#284)

- stats module: fix stats.list() returning nothing, regressed in 2.0.0

- policy.TLS_FORWARD: refusal when configuring with multiple IPs (#306)

- cache: fix broken refresh of insecure records that were about to expire

- fix the hints module on some systems, e.g. Fedora (came back on 2.0.0)

- build with older gnutls (conditionally disable features)

- fix the predict module to work with insecure records & cleanup code

Knot Resolver 2.0.0 (2018-01-31)

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

Incompatible changes

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

- systemd: change unit files to allow running multiple instances,

  deployments with single instance now must use `kresd@1.service`

  instead of `kresd.service`; see kresd.systemd(8) for details

- systemd: the directory for cache is now /var/cache/knot-resolver

- unify default directory and user to `knot-resolver`

- directory with trust anchor file specified by -k option must be writeable

- policy module is now loaded by default to enforce RFC 6761;

  see documentation for policy.PASS if you use locally-served DNS zones

- drop support for alternative cache backends memcached, redis,

  and for Lua bindings for some specific cache operations

- REORDER_RR option is not implemented (temporarily)

New features

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

- aggressive caching of validated records (RFC 8198) for NSEC zones;

  thanks to ICANN for sponsoring this work.

- forwarding over TLS, authenticated by SPKI pin or certificate.

  policy.TLS_FORWARD pipelines queries out-of-order over shared TLS connection

  Beware: Some resolvers do not support out-of-order query processing.

  TLS forwarding to such resolvers will lead to slower resolution or failures.

- trust anchors: you may specify a read-only file via -K or --keyfile-ro

- trust anchors: at build-time you may set KEYFILE_DEFAULT (read-only)

- ta_sentinel module implements draft ietf-dnsop-kskroll-sentinel-00,

  enabled by default

- serve_stale module is prototype, subject to change

- extended API for Lua modules

Bugfixes

--------

- fix build on osx - regressed in 1.5.3 (different linker option name)

* Wed Feb 07 2018 Fedora Release Engineering <releng@fedoraproject.org> - 1.5.3-1.1

- Rebuilt for https://fedoraproject.org/wiki/Fedora_28_Mass_Rebuild

* 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
