Fedora 29: knot-resolver FEDORA-2019-20f95b0b39
Summary
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
* Wed Jul 10 2019 Tomas Krizek
- update to new upstream version 4.1.0
- add kres-cache-gc.service
* Wed May 29 2019 Tomas Krizek
- 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
- Rebuilt for https://fedoraproject.org/wiki/Fedora_30_Mass_Rebuild

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
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
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)
