* middleware/file: add DNSSEC support
Add tests for DNSSEC and check if everything is working.
* add signatures
* tweak
* Add DNSSEC signing tests for DNAME
* Just sign it all
When CoreDNS starts up and can't get a zone transfer going the Apex is
empty. This `nil` is then transformed into wireformat, which fails with
a nil pointer dereference in Go DNS.
In this case we should just return SERVFAIL, because we don't have any
info (yet). Note the lookup code returned NXDOMAIN, which is correct
from a lookup standpoint, but also invalidates every name in the future
loaded zone.
Anyway, look for an apex before doing the lookup and return SERVFAIL if
nothing is found.
Fixes#679
Limit the options in both errors and log middleware, just output to
stdout and let someone else (journald,docker) care about where to route
the logs. This removes syslog and logging to a file.

* Add external service cnames
* remove cruft
* update CI k8s version
* change CI k8s version
* min k8s ver for ext services
* trying k8s 1.5
* k8s 1.5 requires ports spec
* remove kruft
* update dns schema version
* Test DNAME handling
If the DNAME itself matches the QTYPE, and the owner name matches QNAME,
the relevant DNAME RR should be included in the answer section.
Other parts of RFC 6672 are not implemented yet and hence left untested.
* Implement the DNAME substitution
As specified in RFC 6672, a DNAME substitution is performed by replacing
the suffix labels of the name being sought matching the owner name of
the DNAME resource record with the string of labels in the RDATA field.
The matching labels end with the root label in all cases. Only whole
labels are replaced.
* Handle DNAME redirection
A CNAME RR is created on-the-fly for the DNAME redirection. Be aware
that we do not have all the edge cases covered yet.
* Test DNAME owner name matching the QNAME
A DNAME RR redirects DNS names subordinate to its owner name; the owner
name of a DNAME is NOT redirected itself.
* Ignore names next to and below a DNAME record
According to RFC 6672, resource records MUST NOT exist at any subdomain
of the owner of a DNAME RR. When loading a zone, those names below the
DNAME RR will be quietly ignored.
* Streamline DNAME processing
Instead of checking DNAMEs during lookup, we use a preloaded list of
DNAME RRs to streamline the process without any runtime performance
penalty:
* When loading the zone, keep a record of any DNAME RRs.
* If there aren't any DNAMEs in the zone, just do the lookup as usual.
* Only when the zone has one or more DNAME records, we look for the
matching DNAME and ignore confronting subdomain(s) in the process.
* Make it easier to trace back through test errors
* Make DNAME handling part of lookup routine
DNAME processing is invoked only if the zone has at least one DNAME RR.
* Put DNAME resolution inside the searching of a hit
We can drop some of the other ideas; we don't need to track if we
have DNAMEs in the zone it just follows naturally from the current
lookup code.

* middleware/chaos: fix version
Move the version setting into a init function so it is done early. Then
tweak the setup code for chaos a bit to correctly pick this version up.
Add an integration test to pick this up in the toplevel test/ directory.
Fixes#667
* Update tests
Make the default target do nothing and put the actual release under a
'release' target. Prevent accidentally committing unwanted commits to
the repo.
Tested with `make -f Makefile.release -n`.
* middleware/file: correctly parse the stanza
Parsing the file stanza would give precedence to 'transfer' and ignore
other bits if it wasn't specified.
This change fixes the parsing. The actually external CNAME retrieval is
working fine (once the upstream is correctly parsed).
This wasn't caught in tests, because we lack a parsing test for this.
Fixes#657
* Add tests
Check message for expired sig and don't cache those.
Aside: This hack of caching entire messages is probably something we
should stop doing at some point in the future and do this on a per RRset
basis.

* Revert "middleware/proxy: Make Unhealthy a pointer (#615)"
This reverts commit acbf522ceb.
* middleware/proxy: add proper locking
This add the proper locking around `Unhealthy`.
This method parses the Host field in the service. It returns 1 or 3
things 1) it is a host 2) an IPv4 address or an 3) IPv6 address.
This simplifies some code a bit and allows for 1 way of parsing the Host
field.
This *only* parse the Host field, Mail and/or Text values should be
checked separately.
We reuse the dns.TypeXXX values for this as to not invent anything new.
Add a MAINTAINERS file. It's not generated and not as elaborate (i.e. no
focus areas) as the one prometheus uses. But it's a start.
Generated with `git shortlog -s -n`, everyone with more than 5 commits.
Docs are put in `Makefile.release`.
Fixes#566
* Add fallthrough support for Kubernetes
This enables registering other services in the same zone as
Kubernetes services. This also re-orders the middleware chain
so that Kubernetes comes before other types, in order to make
this work out-of-the-box.
* Remove extra line
* Implements tracing in the native gRPC server
* Undo some unnecessary changes
* Properly revert trace/setup.go this time
* Some very very basic tests
* Remove warning for non-Trace middleware
