------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2018-fe5a6ed3b7 2018-02-27 17:16:42.082266 ------------------------------------------------------------------------------- -
Name : knot-resolver Product : Fedora 27 Version : 2.1.0 Release : 1.fc27 URL : https://www.knot-resolver.cz/ Summary : Caching full DNS Resolver 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, start a single kresd instance:
If you run into issues with activation of the service or its sockets, either update your selinux-policy package or turn off selinux (setenforce 0). https://bugzilla.redhat.com/show_bug.cgi?id=1366968 https://bugzilla.redhat.com/show_bug.cgi?id=1543049
------------------------------------------------------------------------------- - Update Information:
Knot Resolver 2.1.0 (2018-02-16) ================================ Incompatible changes -------------------- - stats: remove tracking of expiring records (predict uses another way) - systemd: re-use a single kresd.socket and kresd- tls.socket - 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(7) 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) ---- 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 ------------------------------------------------------------------------------- - References:
