From 0d2cd47617b423f37d7425be7a56ae2fca8ff9f6 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 3 Dec 2015 18:31:24 +0100 Subject: resolved: add a simple trust anchor database as additional RR source 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. --- src/resolve/resolved-manager.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'src/resolve/resolved-manager.c') diff --git a/src/resolve/resolved-manager.c b/src/resolve/resolved-manager.c index 62562f0d24..5a3696ccb0 100644 --- a/src/resolve/resolved-manager.c +++ b/src/resolve/resolved-manager.c @@ -478,6 +478,10 @@ int manager_new(Manager **ret) { m->read_resolv_conf = true; m->need_builtin_fallbacks = true; + r = dns_trust_anchor_load(&m->trust_anchor); + if (r < 0) + return r; + r = sd_event_default(&m->event); if (r < 0) return r; @@ -572,6 +576,8 @@ Manager *manager_free(Manager *m) { free(m->llmnr_hostname); free(m->mdns_hostname); + dns_trust_anchor_flush(&m->trust_anchor); + free(m); return NULL; -- cgit v1.2.3-54-g00ecf
