Wim 4f5d5020b8 dns: fix memoryleak by upgrading outdated miekg/dns (#6748)
* Add updated github.com/miekg/dns to go modules
* Add updated github.com/miekg/dns to vendor
* Fix github.com/miekg/dns api breakage
* Decrease size when trimming UDP packets
Need more room for the header(?), if we don't decrease the size we get an
"overflow unpacking uint32" from the dns library
* Fix dns truncate tests with api changes
* Make windows build working again. Upgrade x/sys and x/crypto and vendor
This upgrade is needed because of API breakage in x/sys introduced
by the minimal x/sys dependency of miekg/dns

This API breakage has been fixed in commit

Nicolas Benoit 0e9a2e5bd0 Fix dns service SRV lookup when service address is a fqdn
Refactor dns to have same behavior between A and SRV.
Current implementation returns the node name instead of the service
address.
With this fix when querying for SRV record service address is return in
the SRV record.
And when performing a simple dns lookup it returns a CNAME to the
service address.

Aestek f669bb7b0f Add support for DNS config hot-reload (#4875)
The DNS config parameters `recursors` and `dns_config.*` are now hot
reloaded on SIGHUP or `consul reload` and do not need an agent restart
to be modified.
Config is stored in an atomic.Value and loaded at the beginning of each
request. Reloading only affects requests that start _after_ the
reload. Ongoing requests are not affected. To match the current
behavior the recursor handler is loaded and unloaded as needed on config
reload.

Pierre Souchay 251156eb68 Added SOA configuration for DNS settings. (#4714)
This will allow to fine TUNE SOA settings sent by Consul in DNS responses,
for instance to be able to control negative ttl.

Will fix: https://github.com/hashicorp/consul/issues/4713

# Example

Override all settings:

* min_ttl: 0 => 60s
* retry: 600 (10m) => 300s (5 minutes),
* expire: 86400 (24h) => 43200 (12h)
* refresh: 3600 (1h) => 1800 (30 minutes)

```
consul agent -dev -hcl 'dns_config={soa={min_ttl=60,retry=300,expire=43200,refresh=1800}}'
```

Result:
```

Paul Banks b83bbf248c Add Proxy Upstreams to Service Definition (#4639)
* Refactor Service Definition ProxyDestination.

This includes:
 - Refactoring all internal structs used
 - Updated tests for both deprecated and new input for:
   - Agent Services endpoint response
   - Agent Service endpoint response
   - Agent Register endpoint
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Register
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Services endpoint response
   - Catalog Node endpoint response
   - Catalog Service endpoint response
 - Updated API tests for all of the above too (both deprecated and new forms of register)

TODO:
 - config package changes for on-disk service definitions
 - proxy config endpoint
 - built-in proxy support for new fields

* Agent proxy config endpoint updated with upstreams

* Config file changes for upstreams.

* Add upstream opaque config and update all tests to ensure it works everywhere.

* Built in proxy working with new Upstreams config

* Command fixes and deprecations

* Fix key translation, upstream type defaults and a spate of other subtele bugs found with ned to end test scripts...

TODO: tests still failing on one case that needs a fix. I think it's key translation for upstreams nested in Managed proxy struct.

* Fix translated keys in API registration.
≈

* Fixes from docs
 - omit some empty undocumented fields in API
 - Bring back ServiceProxyDestination in Catalog responses to not break backwards compat - this was removed assuming it was only used internally.

* Documentation updates for Upstreams in service definition

* Fixes for tests broken by many refactors.

* Enable travis on f-connect branch in this branch too.

* Add consistent Deprecation comments to ProxyDestination uses

* Update version number on deprecation notices, and correct upstream datacenter field with explanation in docs

Matt Keeler d3ee66eed4
Add ECS option to EDNS responses where appropriate (#4647)
This implements parts of RFC 7871 where Consul is acting as an authoritative name server (or forwarding resolver when recursors are configured)

If ECS opt is present in the request we will mirror it back and return a response with a scope of 0 (global) or with the same prefix length as the request (indicating its valid specifically for that subnet).

We only mirror the prefix-length (non-global) for prepared queries as those could potentially use nearness checks that could be affected by the subnet. In the future we could get more sophisticated with determining the scope bits and allow for better caching of prepared queries that don’t rely on nearness checks.

The other thing this does not do is implement the part of the ECS RFC related to originating ECS headers when acting as a intermediate DNS server (forwarding resolver). That would take a quite a bit more effort and in general provide very little value. Consul will currently forward the ECS headers between recursors and the clients transparently, we just don't originate them for non-ECS clients to get potentially more accurate "location aware" results.

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

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.

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

agent: move agent/consul/structs to agent/structs 2017-08-09 14:32:12 +02:00
Preetha Appan 7f34dc08a5
Added test case with IPV6 bind address for NS records, rewrote tests to use verify library and other code review feedback 2017-08-07 11:11:55 +02:00
Preetha Appan 76319f751d
Added back glue records in NS response, expanded unit test. Also reused same function used in node lookup for adding A/AAAA records in the extra section of the NS response 2017-08-07 11:11:55 +02:00
Preetha Appan f01f17bda3
Don't add A records for NS requests, because the record being returned already resolves correctly. Also fixed all the unit tests, and ignored hostnames that don't meet valid dns hostname criteria 2017-08-07 11:11:55 +02:00
Preetha Appan 37f75a393e
Use sanitized version of node name of server in NS record, and start with "server" rather than "ns" 2017-08-07 11:11:55 +02:00
Preetha Appan f9db387097
Add NS records and A records for each server. Constructs ns host names using the advertise address of the server. 2017-08-07 11:11:54 +02:00
Frank Schroeder 4a4b91a2db agent: fix data races with registerEndpoint
Only register a different endpoint after it has been
fully created.

Frank Schroeder 00f6ba298e dns: fix data race in TestDNS_ServiceLookup_FilterACL
The agent config cannot be modified after start.

Frank Schroeder 727b6444ad dns: fix data races in DNS compression tests
Make the DisableCompression value configurable at runtime
to allow tests to change it without restarting/recreating
the server.

Frank Schröder 4b51d00458 agent: fix DNS recursor tests (#3190)
The makeRecursor function was using an unreliable mechanism
to start a server with a random port. This patch changes this
so that the server starts on port 0 to let the kernel pick
a free port.

In addition, to similar functions for starting a test DNS
server were folded into one.

Frank Schroeder c4fc581e07 agent: make registerEndpoint private
This is only used for testing.

Frank Schroeder 2b41f2e3a3 agent: make the RPC endpoint overwrite mechanism more transparent
This patch hides the RPC handler overwrite mechanism from the
rest of the code so that it works in all cases and that there
is no cooperation required from the tested code, i.e. we can
drop a.getEndpoint().

Seth Vargo a8f1e7ebf9 Add EDNS0 support (#3131)
This is a refactor of GH-1980. Originally I tried to do a straight
rebase, but the code has changed too much.
