(#246) - prevent UDP packet leaks when using TLS forwarding - fix the hints module also on some other systems, e.g. Gentoo. * Fri Feb 16 2018 Tomas Krizek - 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 - 1.5.3-1.1 - Rebuilt for https://fedoraproject.org/wiki/Fedora_28_Mass_Rebuild * Tue Jan 23 2018 Tomas Krizek - 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 - 1.5.0-2 - add doc package - configure tarball signature verification - add root.hints file - use upstream systemd unit files, paths and user name - migrate configuration to /etc/knot-resolver - use user knot-resolver - store cache in /var/cache/knot-resolver - use systemd alias knot-resolver -> kresd * Mon Nov 06 2017 Petr Špaček - 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 - 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 - 1.3.1-1.1 - Rebuilt for https://fedoraproject.org/wiki/Fedora_27_Mass_Rebuild * Tue Jul 11 2017 Petr Spacek - 1.3.1-2 - build experimental command line interface "kresc" * Tue Jul 11 2017 Petr Spacek - 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 - 1.2.5-1 - new upstream relase + security: layer/validate: clear AD if closest encloser proof has opt-outed NSEC3 (#169) + security: layer/validate: check if NSEC3 records in wildcard expansion proof has an opt-out + security: dnssec/nsec: missed wildcard no-data answers validation has been implemented + fix: trust anchors: Improve trust anchors storage format (#167) + fix: trust anchors: support non-root TAs, one domain per file + fix: policy.DENY: set AA flag and clear AD flag + fix: lib/resolve: avoid unnecessary DS queries + fix: lib/nsrep: don't treat servers with NOIP4 + NOIP6 flags as timeouted + fix: layer/iterate: During packet classification (answer vs. referral) don't analyze AUTHORITY section in authoritative answer if ANSWER section contains records that have been requested + enhancement: modules/dnstap: a DNSTAP support module (Contributed by Vicky Shrestha) + enhancement: modules/workarounds: a module adding workarounds for known DNS protocol violators + enhancement: layer/iterate: fix logging of glue addresses + enhancement: kr_bitcmp: allow bits=0 and consequently 0.0.0.0/0 matches in view and renumber modules. + enhancement: modules/padding: Improve default padding of responses (Contributed by Daniel Kahn Gillmor) + enhancement: New kresc client utility (experimental;
