Name        : knot-resolver
Product     : Fedora 28
Version     : 2.4.0
Release     : 1.fc28
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:
$ systemctl start kresd(a)1.service

Knot Resolver 2.4.0 (2018-07-03) ================================  Incompatible
changes -------------------- - minimal libknot version is now 2.6.7 to pull in
latest fixes (#366)  Security -------- - fix a rare case of zones incorrectly
dowgraded to insecure status (!576)  New features ------------ - TLS session
resumption (RFC 5077), both server and client (!585, #105)   (disabled when
compiling with gnutls < 3.5) - TLS_FORWARD policy uses system CA certificate
store by default (!568) - aggressive caching for NSEC3 zones (!600) - optional
protection from DNS Rebinding attack (module rebinding, !608) - module bogus_log
to log DNSSEC bogus queries without verbose logging (!613)  Bugfixes -------- -
prefill: fix ability to read certificate bundle (!578) - avoid turning off qname
minimization in some cases, e.g. co.uk. (#339) - fix validation of explicit
wildcard queries (#274) - dns64 module: more properties from the RFC implemented
(incl. bug #375)  Improvements ------------ - systemd: multiple enabled kresd
instances can now be started using kresd.target - ta_sentinel: switch to version
14 of the RFC draft (!596) - support for glibc systems with a non-Linux kernel
(!588) - support per-request variables for Lua modules (!533) - support custom
HTTP endpoints for Lua modules (!527)
