2016-01-03resolved: add negative trust anchro support, and add trust anchor ↵Lennart Poettering
configuration files This adds negative trust anchor support and allows reading trust anchor data from disk, from files /etc/systemd/dnssec-trust-anchors.d/*.positive and /etc/systemd/dnssec-trust-anchros.d/*.negative, as well as the matching counterparts in /usr/lib and /run. The positive trust anchor files are more or less compatible to normal DNS zone files containing DNSKEY and DS RRs. The negative trust anchor files contain only new-line separated hostnames for which to require no signing. By default no trust anchor files are installed, in which case the compiled-in root domain DS RR is used, as before. As soon as at least one positive root anchor for the root is defined via trust anchor files this buil-in DS RR is not added though.
2015-12-03resolved: add a simple trust anchor database as additional RR sourceLennart Poettering
When doing DNSSEC lookups we need to know one or more DS or DNSKEY RRs as trust anchors to validate lookups. With this change we add a compiled-in trust anchor database, serving the root DS key as of today, retrieved from: https://data.iana.org/root-anchors/root-anchors.xml The interface is kept generic, so that additional DS or DNSKEY RRs may be served via the same interface, for example by provisioning them locally in external files to support "islands" of security. The trust anchor database becomes the fourth source of RRs we maintain, besides, the network, the local cache, and the local zone.
