Matt Keeler 0fd7e97c2d Merge remote-tracking branch 'origin/master' into bugfix/prevent-multi-cname 2018-07-10 10:26:45 -04:00
Matt Keeler cbf8f14451 Ensure TXT RRs always end up in the Additional section except for ANY or TXT queries 
This also changes where the enforcement of the enable_additional_node_meta_txt configuration gets applied.

formatNodeRecord returns the main RRs and the meta/TXT RRs in separate slices. Its then up to the caller to add to the appropriate sections or not.

Matt Keeler 6cc0422408 Add configuration entry to control including TXT records for node meta in DNS responses 
If set to false, the only way to retrieve TXT records for node meta is to specifically query for TXT records.

Pierre Souchay be39fb20cc [BUGFIX] do not break when TCP DNS answer exceeds 64k 
It will avoid having discovery broken when having large number
of instances of a service (works with SRV and A* records).

Fixes https://github.com/hashicorp/consul/issues/3850

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.

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'.

Fixes #3200
