= Proposed System Wide Change: Default Local DNS Resolver = https://fedoraproject.org/wiki/Changes/Default_Local_DNS_Resolver Change owner(s): P J P <pjp@xxxxxxxxxxxxxxxxx>, Pavel Šimerda <pavlix@xxxxxxxxxx>, Tomas Hozza <thozza@xxxxxxxxxx> To install a local DNS resolver trusted for the DNSSEC validation running on 127.0.0.1:53. This must be the only name server entry in /etc/resolv.conf. The automatic name server entries received via dhcp/vpn/wireless configurations should be stored separately, as transitory name servers to be used by the trusted local resolver. In all cases, DNSSEC validation will be done locally. This change was submitted after the Submission deadline. == Detailed Description == There are growing instances of discussions and debates about the need for a trusted DNSSEC validating local resolver running on 127.0.0.1:53. There are multiple reasons for having such a resolver, importantly security & usability. Security & protection of user's privacy becomes paramount with the backdrop of the increasingly snooping governments and service providers world wide. People use Fedora on portable/mobile devices which are connected to diverse networks as and when required. The automatic DNS configurations provided by these networks are never trustworthy for DNSSEC validation. As currently there is no way to establish such trust. Apart from trust, these name servers are often known to be flaky and unreliable. Which only adds to the overall bad and at times even frustrating user experience. In such a situation, having a trusted local DNS resolver not only makes sense but is in fact badly needed. It has become a need of the hour. (See: [1], [2], [3]) Going forward, as DNSSEC and IPv6 networks become more and more ubiquitous, having a trusted local DNS resolver will not only be imperative but be unavoidable. Because it will perform the most important operation of establishing trust between two parties. All DNS literature strongly recommends it. And amongst all discussions and debates about issues involved in establishing such trust, it is unanimously agreed upon and accepted that having a trusted local DNS resolver is the best solution possible. It'll simplify and facilitate lot of other design decisions and application development in future. (See: [1], [2], [3]) People:- * Petr Spacek * Paul Wouters * Simo Sorce * Dmitri Pal * Carlos O'Donell == Scope == * Proposal owners: Proposal owners shall have to ** define the syntax and semantics for new configuration parameters/files. ** persuade and coordinate with the other package owners to incorporate new changes/workflow in their applications. * Other developers: (especially NetworkManager and the likes) ** would have to implement the new features/workflow for their applications adhering to the new configurations and assuming the availability of the '''trusted''' local DNS resolver. ** NetworkManager already has features & capability to support local DNS resolvers. Though few details are still under development, but are expected to realize in near future. Please see [4] * Release engineering: ** would have to ensure that trusted local DNS resolver is available throughout the installation stage and the same is installed on all installations including LiveCDs etc. * Policies and guidelines: ** the chosen trusted DNS resolver package(ex dnsmasq or dnssec-trigger etc.) would have to ensure that their DNS resolver starts at boot time and works out of the box without any user intervention. ** NetworkManager and others would have to be told to not tamper with the local nameserver entries in '/etc/resolv.conf' and save the dynamic nameserver entries in a separate configuration file.
