Deleting from memdb inside an interation can cause a panic from Iterator.Next. This
case is technically safe (for now) because the iterator is using the root radix tree
not a modified one.
However this could break at any time if someone adds an insert or delete to the coordinates table
before this place in the function.
It also sets a bad example, because generally deletes in an interator are not safe. So this
commit uses the pattern we have in other places to move the deletes out of the iteration.
After fixing that bug I uncovered a couple more:
Fix an issue where we might try to cross sign a cert when we never had a valid root.
Fix a potential issue where reconfiguring the CA could cause either the Vault or AWS PCA CA providers to delete resources that are still required by the new incarnation of the CA.
Using withEnterpriseSchema() we can apply any enterprise schema changes
with a single shim, removing the need to duplicate all of the table
definitions.
Also move all the catalog schemas to a new file to shrink catalog.go a bit.
I believe this commit also fixes a bug. Previously RPCMaxConnsPerClient was not being re-read from the RuntimeConfig, so passing it to Server.ReloadConfig was never changing the value.
Also improve the test runtime by not doing a lot of unnecessary work.
The field was not being included in the cache info key. This would result in a DNS request for
web.service.consul returning the same result as web.ingress.consul, when those results should
not be the same.
include all fields when fuzzing in tests
split tests by struct type
Ensure the new value for the field is different
fuzzer.Fuzz could produce the same value again in some cases.
Use a custom fuzz function for QueryOptions. That type is an embedded struct in the request types
but only one of the fields is important to include in the cache key.
Move enterpriseMetaField to an oss file so that we can change it in enterprise.
* Fix bug in usage metrics that caused a negative count to occur
There were a couple of instances were usage metrics would do the wrong
thing and result in incorrect counts, causing the count to attempt to
decrement below zero and return an error. The usage metrics did not
account for various places where a single transaction could
delete/update/add multiple service instances at once.
We also remove the error when attempting to decrement below zero, and
instead just make sure we do not accidentally underflow the unsigned
integer. This is a more graceful failure than returning an error and not
allowing a transaction to commit.
* Add changelog
This change allows us to re-use these functions in other places without the Builder, and makes it
more explicit about which functions can warn/error and which can not.
A golden file makes the expected value easier to work with. This change also
removes a number of shims for enterprise and replaces them with a single one
for the golden filename.
* Display a warning when rpc.enable_streaming = true is set on a client
This option has no effect when running as an agent
* Added warning when server starts with use_streaming_backend but without rpc.enable_streaming
* Added unit test
It is no safe to assumes that the mapstructure keys will contain all the keys because some config can be specified
with command line flags or literals.
This change allows us to remove the json marshal/unmarshal cycle for command line flags, which will allow
us to remove all of the hcl/json struct tags on config fields.
These types are used as values (not pointers) in other structs. Using a pointer receiver causes
problems when the value is printed. fmt will not call the String method if it is passed a value
and the String method has a pointer receiver. By using a value receiver the correct string is printed.
Also remove some unused methods.
TestEnvoy.Close used e.stream.recvCh == nil to indicate the channel had already
been closed, so that TestEnvoy.Close can be called multiple times. The recvCh
was not protected by a lock, so setting it to nil caused a data race with any
goroutine trying to read from the channel.
Instead set the stream to nil. The stream is guarded by a lock, so it does not race.
This change allows us to test the agent/xds package using -race.
This way we only have to wait for the serf barrier to pass once before
we can upgrade to v2 acls. Without this patch every restart needs to
re-compute the change, and potentially if a stray older node joins after
a migration it might regress back to v1 mode which would be problematic.
This can happen when one other node in the cluster such as a client is unable to communicate with the leader server and sees it as failed. When that happens its failing status eventually gets propagated to the other servers in the cluster and eventually this can result in RPCs returning “No cluster leader” error.
That error is misleading and unhelpful for determing the root cause of the issue as its not raft stability but rather and client -> server networking issue. Therefore this commit will add a new error that will be returned in that case to differentiate between the two cases.
In some circumstances this endpoint will have no results in it (dues to
ACLs, Namespaces or filtering).
This ensures that the response is at least an empty array (`[]`) rather
than `null`
HTTPUseCache is only used is a gate for allowing QueryOptions.UseCache to be enabled. By
moving it to the place where the query options are set, this behaviour is more obvious.
Also remove parseInternal which was an alias for parse.
Previously the tokens would fail to insert into the secondary's state
store because the AuthMethod field of the ACLToken did not point to a
known auth method from the primary.

And remove the devMode field from builder.
This change helps make the Builder state more explicit by moving inputs to the BuilderOps struct,
leaving only fields that can change during Builder.Build on the Builder struct.
Using the LiteralSource makes it much easier to find default values, because an IDE reports
the location of a default. With an HCL string they are harder to discover.
Also removes unnecessary mapstructure.Decodes of constant values.
A vulnerability was identified in Consul and Consul Enterprise (“Consul”) such that operators with `operator:read` ACL permissions are able to read the Consul Connect CA configuration when explicitly configured with the `/v1/connect/ca/configuration` endpoint, including the private key. This allows the user to effectively privilege escalate by enabling the ability to mint certificates for any Consul Connect services. This would potentially allow them to masquerade (receive/send traffic) as any service in the mesh.
--
This PR increases the permissions required to read the Connect CA's private key when it was configured via the `/connect/ca/configuration` endpoint. They are now `operator:write`.
Previously the listener was being passed to a closure in a loop without
capturing the loop variable. The result is only the last listener is
used, so the http/https servers only listen on one address.
This problem is fixed by capturing the variable by passing it into a
function.
This PR updates the tags that we generate for Envoy stats.
Several of these come with breaking changes, since we can't keep two stats prefixes for a filter.

The Intention.Apply RPC is quite large, so this PR attempts to break it down into smaller functions and dissolves the pre-config-entry approach to the breakdown as it only confused things.
Header is: X-Consul-Default-ACL-Policy=<allow|deny>
This is of particular utility when fetching matching intentions, as the
fallthrough for a request that doesn't match any intentions is to
enforce using the default acl policy.
Most packages should pass the race detector. An exclude list ensures
that new packages are automatically tested with -race.
Also fix a couple small test races to allow more packages to be tested.
Returning readyCh requires a lock because it can be set to nil, and
setting it to nil will race without the lock.
Move the TestServer.Listening calls around so that they properly guard
setting TestServer.l. Otherwise it races.
Remove t.Parallel in a small package. The entire package tests run in a
few seconds, so t.Parallel does very little.
In auto-config, wait for the AutoConfig.run goroutine to stop before
calling readPersistedAutoConfig. Without this change there was a data
race on reading ac.config.
defaultMetrics was being set at package import time, which meant that it received an instance of
the original default. But lib/telemetry.InitTelemetry sets a new global when it is called.
This resulted in the metrics being sent nowhere.
This commit changes defaultMetrics to be a function, so it will return the global instance when
called. Since it is called after InitTelemetry it will return the correct metrics instance.
The Catalog, Config Entry, KV and Session resources potentially re-validate the input as its coming in. We need to prevent snapshot restoration failures due to missing namespaces or namespaces that are being deleted in enterprise.
This ensures the metrics proxy endpoint is ACL protected behind a
wildcard `service:read` and `node:read` set of rules. For Consul
Enterprise these will need to span all namespaces:
```
service_prefix "" { policy = "read" }
node_prefix "" { policy = "read" }
namespace_prefix "" {
service_prefix "" { policy = "read" }
node_prefix "" { policy = "read" }
}
```
This PR contains just the backend changes. The frontend changes to
actually pass the consul token header to the proxy through the JS plugin
will come in another PR.
