Pierre Souchay	0b7f620dc6	Allow to control the number of A/AAAA Record returned by DNS ... This allows to have randomized resource records (i.e. each answer contains only one IP, but the IP changes every request) for A, AAAA records. It will fix https://github.com/hashicorp/consul/issues/3355 and https://github.com/hashicorp/consul/issues/3937 See https://github.com/hashicorp/consul/issues/3937#issuecomment-370610509 for details. It basically add a new option called `a_record_limit` and will not return more than a_record_limit when performing A, AAAA or ANY DNS requests. The existing `udp_answer_limit` option is still working but should be considered as deprecated since it works only with DNS clients not supporting EDNS.	7 years ago

Frank Schröder	350932161d	dns: return NXDOMAIN if datacenter is invalid (#3200) (#3596) ... Queries to the DNS server can contain an optional datacenter name in the query name. You can query for 'foo.service.consul' or 'foo.service.dc.consul' to get a response for either the default or a specific datacenter. Datacenter names cannot have dots, therefore the datacenter name can refer to only one element in the DNS query name. The DNS server allowed extra labels between the optional datacenter name and the domain and returned a valid response instead of returning NXDOMAIN. For example, if the domain is set to '.consul' then 'foo.service.dc1.extra.consul' should return NXDOMAIN because of 'extra' being between the datacenter name 'dc1' and the domain '.consul'.

Frank Schröder	12216583a1	New config parser, HCL support, multiple bind addrs (#3480) ... * new config parser for agent This patch implements a new config parser for the consul agent which makes the following changes to the previous implementation: * add HCL support * all configuration fragments in tests and for default config are expressed as HCL fragments * HCL fragments can be provided on the command line so that they can eventually replace the command line flags. * HCL/JSON fragments are parsed into a temporary Config structure which can be merged using reflection (all values are pointers). The existing merge logic of overwrite for values and append for slices has been preserved. * A single builder process generates a typed runtime configuration for the agent. The new implementation is more strict and fails in the builder process if no valid runtime configuration can be generated. Therefore, additional validations in other parts of the code should be removed. The builder also pre-computes all required network addresses so that no address/port magic should be required where the configuration is used and should therefore be removed. * Upgrade github.com/hashicorp/hcl to support int64 * improve error messages * fix directory permission test * Fix rtt test * Fix ForceLeave test * Skip performance test for now until we know what to do * Update github.com/hashicorp/memberlist to update log prefix * Make memberlist use the default logger * improve config error handling * do not fail on non-existing data-dir * experiment with non-uniform timeouts to get a handle on stalled leader elections * Run tests for packages separately to eliminate the spurious port conflicts * refactor private address detection and unify approach for ipv4 and ipv6. Fixes #2825 * do not allow unix sockets for DNS * improve bind and advertise addr error handling * go through builder using test coverage * minimal update to the docs * more coverage tests fixed * more tests * fix makefile * cleanup * fix port conflicts with external port server 'porter' * stop test server on error * do not run api test that change global ENV concurrently with the other tests * Run remaining api tests concurrently * no need for retry with the port number service * monkey patch race condition in go-sockaddr until we understand why that fails * monkey patch hcl decoder race condidtion until we understand why that fails * monkey patch spurious errors in strings.EqualFold from here * add test for hcl decoder race condition. Run with go test -parallel 128 * Increase timeout again * cleanup * don't log port allocations by default * use base command arg parsing to format help output properly * handle -dc deprecation case in Build * switch autopilot.max_trailing_logs to int * remove duplicate test case * remove unused methods * remove comments about flag/config value inconsistencies * switch got and want around since the error message was misleading. * Removes a stray debug log. * Removes a stray newline in imports. * Fixes TestACL_Version8. * Runs go fmt. * Adds a default case for unknown address types. * Reoders and reformats some imports. * Adds some comments and fixes typos. * Reorders imports. * add unix socket support for dns later * drop all deprecated flags and arguments * fix wrong field name * remove stray node-id file * drop unnecessary patch section in test * drop duplicate test * add test for LeaveOnTerm and SkipLeaveOnInt in client mode * drop "bla" and add clarifying comment for the test * split up tests to support enterprise/non-enterprise tests * drop raft multiplier and derive values during build phase * sanitize runtime config reflectively and add test * detect invalid config fields * fix tests with invalid config fields * use different values for wan sanitiziation test * drop recursor in favor of recursors * allow dns_config.udp_answer_limit to be zero * make sure tests run on machines with multiple ips * Fix failing tests in a few more places by providing a bind address in the test * Gets rid of skipped TestAgent_CheckPerformanceSettings and adds case for builder. * Add porter to server_test.go to make tests there less flaky * go fmt	7 years ago

Frank Schroeder	bf96857b17	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	7 years ago

Frank Schroeder	7ea11c2f45	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.	7 years ago
