Frank Schroeder d9e2a51887 agent: drop unused code 
This code from http://github.com/hashicorp/consul/pull/3353 is no longer
required.
 2017-08-22 00:02:46 +02:00
Frank Schroeder 4bfcf7b613 dns: replace nameserver lookup with consistent rpc call 
This patch replaces the code which determines the list of servers in the
current cluster with an RPC call to get the list of active consul
service instances which only run on servers.

This replaces the previous implementation which was more complex and
relied on serf messages which can provide a different view than the
consistent response from the raft log.

As a side effect it makes the implementation independent of the server
and the agent which means it works consistently across both. Different
behavior for server and agent was the root cause for the bug in
http://github.com/hashicorp/consul/issue/3047.

Fixes #3407

James Phillips 738ac55d96
Switches to using a read lock for the agent's RPC dispatcher. 
This prevents RPC calls from getting serialized in this spot.

dns: provide correct SOA and NS responses 
This patch changes the behavior of the DNS server as follows:

* The SOA response contains the SOA record in the Answer section instead
  of the Authority section. It also contains NS records in the Authority
  and the corresponding A glue records in the Extra section.
  In addition, CNAMEs are added to the Extra section to make the
  MNAME of the SOA record resolvable.

  AAAA glue records are not yet supported.

* The NS response returns up to three random servers from the
  consul cluster in the Answer section and the glue A
  records in the Extra section.

  AAAA glue records are not yet supported.

James Phillips 8572931afe Cleans up version 8 ACLs in the agent and the docs. (#3248) 
* Moves magic check and service constants into shared structs package.

* Removes the "consul" service from local state.

Since this service is added by the leader, it doesn't really make sense to
also keep it in local state (which requires special ACLs to configure), and
requires a bunch of special cases in the local state logic. This requires
fewer special cases and makes ACL bootstrapping cleaner.

* Makes coordinate update ACL log message a warning, similar to other AE warnings.

* Adds much more detailed examples for bootstrapping ACLs.

This can hopefully replace https://gist.github.com/slackpad/d89ce0e1cc0802c3c4f2d84932fa3234.
