Dear Knot Resolver users, Knot Resolver 3.2.0 has been released. 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 Full changelog: https://gitlab.labs.nic.cz/knot/knot-resolver/raw/v3.2.0/NEWS Sources: https://secure.nic.cz/files/knot-resolver/knot-resolver-3.2.0.tar.xz GPG signature: https://secure.nic.cz/files/knot-resolver/knot-resolver-3.2.0.tar.xz.asc Documentation: https://knot-resolver.readthedocs.io/en/v3.2.0/ -- Tomas Krizek PGP: 4A8B A48C 2AED 933B D495 C509 A1FB A5F7 EF8C 4869
