* plugin/dnssec: check validityperiod of RRSIGs
Somehow we missed implementing this. If a sig a retrieved from the
cache, but not valid anymore, regenerate it instead of server invalid
signatures.
Fixes#1378
* drop from cache after 3/4 validity
* six days means 6 days
* Add manual pages
Generate manual pages from the README and extend README with Name and
Description sections.
The generation requires 'ronn' which may not be available. Just check in
all generated manual pages.
* plugin/dnssec: implement shotgun from CloudFlare
Put a whole bunch of types in the NSEC bitmap and remove the one that's
being asked for.
Add more records for queries to the apex, SOA, DNSKEY, MX.
After initial startup, see if prometheus is loaded and if so, register
our metrics with it.
Stop doing the init() func and just use the sync.Once so we don't double
registrer our metrics.
* readme: more tests
Add dnssec and file plugin to the test readme. This requires creating a
bunch of files with the right content. Doing so already unconvered an
unconditional type assertion in DNSSEC. This PR will include the fix for
that as well.
Also extended the snippets in the file plugin README, so that they are
whole Corefile - showing more value and checking all corefile snippets.
Create outliner right now is the kubernetes plugin, because even setting
the right env vars will result in:
open /var/run/secrets/kubernetes.io/serviceaccount/token: no such file or directory":
Which we can't create for a test.
* lint
* doc update
Go through all README and fix mistakes, extend example and let more
corefile snippets be test for validity.
* Cant use spefic addr in test
Add a full test server impl in this new package + tests. Move
dnsrecorder into this package as well and finish up the commented out
tests that were left in the old dnsrecorder package.
Update all callers and tests.
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
