Previously this happened to be validating only the chains in the default namespace. Now it will validate all chains in all namespaces when the global proxy-defaults is changed.
* Cleanup the discovery chain compilation route handling
Nothing functionally should be different here. The real difference is that when creating new targets or handling route destinations we use the router config entries name and namespace instead of that of the top level request. Today they SHOULD always be the same but that may not always be the case. This hopefully also makes it easier to understand how the router entries are handled.
* Refactor a small bit of the service manager tests in oss
We used to use the stringHash function to compute part of the filename where things would get persisted to. This has been changed in the core code to calling the StringHash method on the ServiceID type. It just so happens that the new method will output the same value for anything in the default namespace (by design actually). However, logically this filename computation in the test should do the same thing as the core code itself so I updated it here.
Also of note is that newer enterprise-only tests for the service manager cannot use the old stringHash function at all because it will produce incorrect results for non-default namespaces.
The previous value was too conservative and users with many instances
were having problems because of it. This change increases the limit to
8192 which reportedly fixed most of the issues with that.
Related: #4984, #4986, #5050.
This adds acl enforcement to the two endpoints that were missing it.
Note that in the case of getting a services health by its id, we still
must first lookup the service so we still "leak" information about a
service with that ID existing. There isn't really a way around it though
as ACLs are meant to check service names.
* Updates to the Txn API for namespaces
* Update agent/consul/txn_endpoint.go

The backing RPC already existed but the endpoint will be useful for other service syncing processes such as consul-k8s as this endpoint can return all services registered with a node regardless of namespacing.
* Fix segfault when removing both a service and associated check
updateSyncState creates entries in the services and checks maps for
remote services/checks that are not found locally, so that we can then
make sure to delete them in our reconciliation process. However, the
values added to the map are missing key fields that the rest of the code
expects to not be nil.
* Add comment stating Check field can be nil
Something similar already happens inside of the server
(agent/consul/server.go) but by doing it in the general config parsing
for the agent we can have agent-level code rely on the PrimaryDatacenter
field, too.
* Increase raft notify buffer.
Fixes https://github.com/hashicorp/consul/issues/6852.
Increasing the buffer helps recovering from leader flapping. It lowers
the chances of the flapping leader to get into a deadlock situation like
described in #6852.
- Explicitly wait to start the test until the initial AE sync of the node.
- Run the blocking query in the main goroutine to cut down on possible
poor goroutine scheduling issues being to blame for delays.
- If the blocking query is woken up with no index change, rerun the
query. This may happen if the CI server is loaded and time dilation is
happening.
Currently when using the built-in CA provider for Connect, root certificates are valid for 10 years, however secondary DCs get intermediates that are valid for only 1 year. There is no mechanism currently short of rotating the root in the primary that will cause the secondary DCs to renew their intermediates.
This PR adds a check that renews the cert if it is half way through its validity period.
In order to be able to test these changes, a new configuration option was added: IntermediateCertTTL which is set extremely low in the tests.
* Add CreateCSRWithSAN
* Use CreateCSRWithSAN in auto_encrypt and cache
* Copy DNSNames and IPAddresses to cert
* Verify auto_encrypt.sign returns cert with SAN
* provide configuration options for auto_encrypt dnssan and ipsan
* rename CreateCSRWithSAN to CreateCSR
* 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
Deregistering a service from the catalog automatically deregisters its
checks, however the agent still performs a deregister call for each
service checks even after the service has been deregistered.
With ACLs enabled this results in logs like:
"message:consul: "Catalog.Deregister" RPC failed to server
server_ip:8300: rpc error making call: rpc error making call: Unknown
check 'check_id'"
This change removes associated checks from the agent state when
deregistering a service, which results in less calls to the servers and
supresses the error logs.
* Renamed structs.IntentionWildcard to structs.WildcardSpecifier
* Refactor ACL Config
Get rid of remnants of enterprise only renaming.
Add a WildcardName field for specifying what string should be used to indicate a wildcard.
* Add wildcard support in the ACL package
For read operations they can call anyAllowed to determine if any read access to the given resource would be granted.
For write operations they can call allAllowed to ensure that write access is granted to everything.
* Make v1/agent/connect/authorize namespace aware
* Update intention ACL enforcement
This also changes how intention:read is granted. Before the Intention.List RPC would allow viewing an intention if the token had intention:read on the destination. However Intention.Match allowed viewing if access was allowed for either the source or dest side. Now Intention.List and Intention.Get fall in line with Intention.Matches previous behavior.
Due to this being done a few different places ACL enforcement for a singular intention is now done with the CanRead and CanWrite methods on the intention itself.
* Refactor Intention.Apply to make things easier to follow.
Sometimes, we have lots of errors in cross calls between DCs (several hundreds / sec)
Enrich the log in order to help diagnose the root cause of issue.
Before we were issuing 1 watch for every service in the services listing which would have caused the agent to process many more identical events simultaneously.
Restore a few more service-kind index updates so blocking in ServiceDump works in more cases
Namely one omission was that check updates for dumped services were not
unblocking.
Also adds a ServiceDump state store test and also fix a watch bug with the
normal dump.
Follow-on from #6916
• Renamed EnterpriseACLConfig to just Config
• Removed chained_authorizer_oss.go as it was empty
• Renamed acl.go to errors.go to more closely describe its contents
* 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
* relax requirements for auto_encrypt on server
* better error message when auto_encrypt and verify_incoming on
* docs: explain verify_incoming on Consul clients.
* Increase number to test ignore. Consul Enterprise has more flags and since we are trying to reduce the differences between both code bases, we are increasing the number in oss. The semantics don't change, it is just a cosmetic thing.
* Introduce agent.initEnterprise for enterprise related hooks.
* Sync test with ent version.
* Fix import order.
* revert error wording.
Ensure we close the Sentinel Evaluator so as not to leak go routines
Fix a bunch of test logging so that various warnings when starting a test agent go to the ltest logger and not straight to stdout.
Various canned ent meta types always return a valid pointer (no more nils). This allows us to blindly deref + assign in various places.
Update ACL index tracking to ensure oss -> ent upgrades will work as expected.
Update ent meta parsing to include function to disallow wildcarding.
Also update the Docs and fixup the HTTP API to return proper errors when someone attempts to use Namespaces with an OSS agent.
Add Namespace HTTP API docs
Make all API endpoints disallow unknown fields
* Implement endpoint to query whether the given token is authorized for a set of operations
* Updates to allow for remote ACL authorization via RPC
This is only used when making an authorization request to a different datacenter.
* Adds 'limits' field to the upstream configuration of a connect proxy
This allows a user to configure the envoy connect proxy with
'max_connections', 'max_queued_requests', and 'max_concurrent_requests'. These
values are defined in the local proxy on a per-service instance basis
and should thus NOT be thought of as a global-level or even service-level value.

* Doc fixes; tests for erroring if State is modified via API
* More review cleanup
* Uncomment tests!
* Minor suggested clean ups
Replaces WaitForLeader with WaitForTestAgent. This waits to make sure
that the node itself is correctly registered in the catalog before
attempting additional registrations.
* Change CA Configure struct to pass Datacenter through
* Remove connect/ca/plugin as we don't have immediate plans to use it.
We still intend to one day but there are likely to be several changes to the CA provider interface before we do so it's better to rebuild from history when we do that work properly.
* Rename PrimaryDC; fix endpoint in secondary DCs
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.
