Blake Covarrubias	a0cd3dd88e	Add DNS recursor strategy option (#10611) ... This change adds a new `dns_config.recursor_strategy` option which controls how Consul queries DNS resolvers listed in the `recursors` config option. The supported options are `sequential` (default), and `random`.

Daniel Nephin	4bf58d8e6a	dns: improve naming of error to match DNS terminology ... Co-authored-by: Blake Covarrubias <blake@covarrubi.as>	3 years ago
Dhia Ayachi	f0cd1441a9	fix truncate when NS is set ... Also: fix test to catch the issue	3 years ago
Daniel Nephin	204bf2b345	dns: correct rcode for qtype not supported ... A previous commit started using QueryRefuced, but that is not correct. QueryRefuced refers to the OpCode, not the query type. Instead use errNoAnswer because we have no records for that query type.	3 years ago
Daniel Nephin	d116bda958	dns: remove network parameter from two funcs ... Now that trimDNSResponse is handled by the caller we don't need to pass this value around. We can remove it from both the serviceLookup struct, and two functions.	3 years ago
Daniel Nephin	42f7963252	dns: trim response immediately before the write ... Previously the response was being trimmed before adding the EDNS values, which could cause it to exceed the max size.	3 years ago
Daniel Nephin	436a02af31	dns: handle errors from dispatch	3 years ago
Daniel Nephin	9267b09c32	dns: error response from dispatch ... So that dispatch can communicate status back to the caller.	3 years ago
Daniel Nephin	68d6f1315f	dns: refactor dispatch to use an explicit return in each case ... In preparation for changing the return value, so that SOA, eDNS trimming and 'not found' errors can be handled in a single place.	3 years ago
Daniel Nephin	b96c8195a5	dns: small refactor to setEDNS to return early ... Using a guard clause instead of a long nested if. The diff is best viewed with whitespace turned off.	3 years ago
Daniel Nephin	4beff900d1	dns: remove unused method ... It was added in 5934f803bf but it was never used.	3 years ago
Daniel Nephin	f31aa12cf1	dns: remove unnecessary function wrapping ... The dispatch function was called from a single place and did nothing but add a default value. Removing it makes code easier to trace by removing an unnecessary hop.	3 years ago
Dhia Ayachi	a64c9a3e62	return an empty record when asked for an addr dns with type other then A, AAAA and ANY (#10401) ... * return an invalid record when asked for an addr dns with type other then A and AAAA * add changelog * fix ANY use case and add a test for it * update changelog type Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * return empty response if the question record type do not match for addr * set comment in the right place * return A\AAAA record in extra section if record type is not A\AAAA for addr * Fix failing test * remove commented code Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * use require for test validation * use variable to init struct * fix failing test * Update agent/dns.go Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * Update .changelog/10401.txt Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * Update agent/dns.go Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * Update agent/dns.go Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * Update agent/dns.go Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * fix compilation error Co-authored-by: Daniel Nephin <dnephin@hashicorp.com>	3 years ago

Daniel Nephin	9b1944dae0	dns: remove goto INVALID and a naked return ... This commit is one small step toward modernizing and making the DNSServer readable.	4 years ago
Daniel Nephin	529f252d5c	rpcclient: Add health.Client and use it in http and dns ... This new package provides a client agent implementation of an interface for fetching the health of services. This approach has a number of benefits: 1. It provides a much more explicit interface. Instead of everything dependency on `RPC()` and `Cache.Get()` for many unrelated things they can depend on a type that are named according to the behaviour it provides. 2. It gives us a single place to vary the behaviour and migrate to a new form of RPC (gRPC). The current implementation has two options (cache, or direct RPC), and in the future we will have more. It is also a great opporunity to start adding `context.Context` args to these operations, which in the future will allow us to cancel the operations. 3. As a concequence of the first, in the Server agent where we make these calls we can replace the current in-memory RPC calls with a thin adapter for the real method. This removes the `net/rpc` machinery from the call in places where it is not needed. This new package is quite small right now, but I think we can expect it to grow to a more reasonable size as other RPC calls are replaced. This change also happens to replace two very similar implementations with a single implementation.	4 years ago
Daniel Nephin	27b36bfc4e	config: move NodeName validation to config validation ... Previsouly it was done in Agent.Start, which is much later then it needs to be. The new 'dns' package was required, because otherwise there would be an import cycle. In the future we should move more of the dns server into the dns package.	4 years ago
Yury Evtikhov	10361dd210	DNS: add IsErrQueryNotFound function for easier error evaluation	4 years ago
Yury Evtikhov	8d18422f19	DNS: fix agent returning SERVFAIL where NXDOMAIN should be returned	4 years ago
Daniel Nephin	a891ee8428	Merge pull request #8176 from hashicorp/dnephin/add-linter-unparam-1 ... lint: add unparam linter and fix some of the issues	4 years ago
Chris Piraino	b3db907bdf	Update gateway-services-nodes API endpoint to allow multiple addresses ... Previously, we were only returning a single ListenerPort for a single service. However, we actually allow a single service to be serviced over multiple ports, as well as allow users to define what hostnames they expect their services to be contacted over. When no hosts are defined, we return the default ingress domain for any configured DNS domain. To show this in the UI, we modify the gateway-services-nodes API to return a GatewayConfig.Addresses field, which is a list of addresses over which the specific service can be contacted.	4 years ago

Daniel Nephin	010a609912	Fix a bunch of unparam lint issues	4 years ago
Pierre Souchay	35d852fd9a	Returns DNS Error NSDOMAIN when DC does not exists (#8103) ... This will allow to increase cache value when DC is not valid (aka return SOA to avoid too many consecutive requests) and will distinguish DC being temporarily not available from DC not existing. Implements https://github.com/hashicorp/consul/issues/8102	5 years ago
Matt Keeler	8837907de4	Make the Agent Cache more Context aware (#8092) ... Blocking queries issues will still be uncancellable (that cannot be helped until we get rid of net/rpc). However this makes it so that if calling getWithIndex (like during a cache Notify go routine) we can cancell the outer routine. Previously it would keep issuing more blocking queries until the result state actually changed.	5 years ago
Kyle Havlovitz	e9e8c0e730	Ingress Gateways for TCP services (#7509) ... * Implements a simple, tcp ingress gateway workflow This adds a new type of gateway for allowing Ingress traffic into Connect from external services. Co-authored-by: Chris Piraino <cpiraino@hashicorp.com>	5 years ago

Chris Piraino	401221de58	Allow users to configure either unstructured or JSON logging (#7130) ... * hclog Allow users to choose between unstructured and JSON logging	5 years ago
Aestek	ba8fd8296f	Add support for dual stack IPv4/IPv6 network (#6640) ... * Use consts for well known tagged adress keys * Add ipv4 and ipv6 tagged addresses for node lan and wan * Add ipv4 and ipv6 tagged addresses for service lan and wan * Use IPv4 and IPv6 address in DNS	5 years ago
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 855e68c859	5 years ago
Matt Keeler	5934f803bf	Sync of OSS changes to support namespaces (#6909)	5 years ago
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.	5 years ago

Akshay Ganeshen	98a35fbe69	dns: support alt domains for dns resolution (#5940) ... this adds an option for an alt domain to be used with dns while migrating to a new consul domain.	6 years ago
Matt Keeler	f3d9b999ee	Add tagged addresses for services (#5965) ... This allows addresses to be tagged at the service level similar to what we allow for nodes already. The address translation that can be enabled with the `translate_wan_addrs` config was updated to take these new addresses into account as well.	6 years ago
Pierre Souchay	4a4c63bda0	Ensure Consul is IPv6 compliant (#5468)	6 years ago
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.	6 years ago
R.B. Boyer	f4a3b9d518	fix typos reported by golangci-lint:misspell (#5434)	6 years ago
Aestek	02f991843f	Fix race condition in DNS when using cache (#5398) ... * Fix race condition in DNS when using cache The healty node filtering was modifying the result from the cache, which caused a crash when multiple queries were made to the same service simultaneously. We now copy the node slice before filtering to ensure we do not modify the data stored in the cache. * Fix wording in dns cache config doc s/dns_max_age/cache_max_age/	6 years ago
Aestek	f1cdfbe40e	Allow DNS interface to use agent cache (#5300) ... Adds two new configuration parameters "dns_config.use_cache" and "dns_config.cache_max_age" controlling how DNS requests use the agent cache when querying servers.	6 years ago
Matt Keeler	1736e24fb3	Don't generate TXT records just to discard them (#5272) ... * Don't generate TXT records just to discard them * Add unit test for formatNodeRecord to ensure it prevents returning TXT records	6 years ago
