* 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
* 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.
Fixes#367#635
* 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 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
Pointer updates are atomic so drop the sync.RWMutex as it is not needed
anymore. This also fixes the race introduced with dfc71df (although I
believe this is the first time we properly tested that code path).
There was no inherent reason *not* to allow multiple listeners for the
monitoring data. Actually enforcing only one listener lead to more code
then just allowing multiple. It's probably not what you want; but
CoreDNS is happy to oblige.
* add proxy tcp
* add truncated for tcp to udp response
* move truncation to scrubbing
* add test that executes upstream over tcp
* middleware/proxy: some tweaks
rename force-tcp to force_tcp to be inline with the rest and use
a dnsOptions struct to put the options in to allow it to be extended.
Add some parse tests as well.
* Fix test and rename dnsOptions Options
According to the code, the default health check interval is 30 seconds,
not 10 as stated in the documentation. (The alternative would be to
adjust the interval in the code.)
* core: add listening for other protocols
Allow CoreDNS to listen for TLS request coming over port 853. This can
be enabled with `tls://` in the config file.
Implement listening for grps:// as well.
a Corefile like:
~~~
. tls://.:1853 {
whoami
tls
}
~~~
Means we listen on 1853 for tls requests, the `tls` config item allows
configuration for TLS parameters. We *might* be tempted to use Caddy's
Let's Encrypt implementation here.
* Refactor coredns/grpc into CoreDNS
This makes gRPC a first class citizen in CoreDNS. Add defines as being
just another server.

In both etcd and k8s don't error log NXDOMAIN as this log spams the logs
for no good reason.
Fixes#568
Better long term solution is log rate limiting for both *log* and
*error*.
This fix updates the Makefile to add the `go lint` check
for the build. This fix also fixes several go lint issues.
NOTE: This fix does not enforce `go lint` (suggestion only).
This fix also ignores the `go lint` error:
```
middleware/middleware.go:72:1: context.Context should be the first parameter of a function
```
as it requires too many changes in API.

* middleware/metrics: survive restart
Keep the handler running during restart. Stopping and starting the
handler results in "address in use" - sometimes, meaning the reload
will be flaky. In turn this behavior means any changes to the monitor
stanza are not picked up.
* remove resync
* Document fallthrough and fix *reverse*
While documenting the fallthrough behavior and testing it I noticed
the did not properly work. This PR does a tiny bit too much as it
- Documents fallthrough
- Fixes fallthrough in reverse
- Makes directives_generate complain on duplicate priorities
- Moved reverse *before* file in middleware.cfg
- Add a test that tests the reverse fallthrough behavior with a file
backend

Make the documentation somewhat shorter (and hopefully clearer in the
process). Also to be on-par with the *auto* middleware, start counting
the referenced zones from 1 (instead of 0).
Some variable cleanups and use the NextOrFailure in the ServeDNS
function.
