------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2019-20f95b0b39 2019-07-19 03:06:25.137701 ------------------------------------------------------------------------------- -
Name : knot-resolver Product : Fedora 29 Version : 4.1.0 Release : 1.fc29 URL : https://www.knot-resolver.cz/ Summary : Caching full DNS Resolver 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
------------------------------------------------------------------------------- - Update Information:
- fixes security issues CVE-2019-10190 and CVE-2019-10191 - https://lists.nic.cz/pipermail/knot-resolver-announce/2019/000009.html ------------------------------------------------------------------------------- - ChangeLog:
* Wed Jul 10 2019 Tomas Krizek <tomas.krizek@nic.cz> - 4.1.0-1 - update to new upstream version 4.1.0 - add kres-cache-gc.service * Wed May 29 2019 Tomas Krizek <tomas.krizek@nic.cz> - 4.0.0.-1 - rebase to new upstream release 4.0.0 - bump Knot DNS libraries to 2.8 (ABI compat) - use new upstream build system - meson - add knot-resolver-module-http package along with new lua dependecies * Fri Feb 1 2019 Fedora Release Engineering <releng@fedoraproject.org> - 3.2.1-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_30_Mass_Rebuild * Thu Jan 10 2019 Tomas Krizek <tomas.krizek@nic.cz> - 3.2.1-1 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 2 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) ------------------------------------------------------------------------------- - References:
