2019-05-01kubernetes: never respond with NXDOMAIN for authority label (#2769)Gravatar Billie Cleek 1-2/+10
* kubernetes: never respond with NXDOMAIN for authority label Return a nodata response when trying to resolve the authority's label for a record type that doesn't match the record type of the authority. This guards against poisoning the authority record by requesting the wrong record type for the authority label. For instance, given an authoritative resolver that uses subdomain delegation for Kubernetes services of a cluster that's configured to use IPv4, the parent may be poisoned by querying it for the authority label of the cluster subdomain with a AAAA record type, which would otherwise (i.e. without this change) return an NXDOMAIN. That is, given cluster.example.com NS 10800 ns.dns.cluster.example.com ns.dns.cluster.example.com A 10800 10.0.1.2 The parent may be poisoned for the SOA TTL by querying it for a AAAA record of ns.dns.cluster.example.com, causing the parent to fail delegate properly until the SOA TTL lapses. * kubernetes: add tests for authority queries

* Remove context.Context from request.Request This removes the context from request.Request and makes all the changes in the code to make it compile again. It's all mechanical. It did unearth some weirdness in that the context was kept in handler structs which may cause havoc with concurrently handling of requests.

2019-01-13Default to upstream to self (#2436)Gravatar Miek Gieben 1-1/+1
* Default to upstream to self This is a backwards incompatible change. This is a massive (cleanup) PR where we default to resolving external names by the coredns process itself, instead of directly forwarding them to some upstream. This ignores any arguments `upstream` may have had and makes it depend on proxy/forward configuration in the Corefile. This allows resolved upstream names to be cached and we have better healthchecking of the upstreams. It also means there is only one way to resolve names, by either using the proxy or forward plugin. The proxy/forward lookup.go functions have been removed. This also lessen the dependency on proxy, meaning deprecating proxy will become easier. Some tests have been removed as well, or moved to the top-level test directory as they now require a full coredns process instead of just the plugin. For the etcd plugin, the entire StubZone resolving is *dropped*! This was a hacky (but working) solution to say the least. If someone cares deeply it can be brought back (maybe)? The pkg/upstream is now very small and almost does nothing. Also the New() function was changed to return a pointer to upstream.Upstream. It also returns only one parameter, so any stragglers using it will encounter a compile error. All documentation has been adapted. This affected the following plugins: * etcd * file * auto * secondary * federation * template * route53 A followup PR will make any upstream directives with arguments an error, right now they are ignored.
