The gist here is that now we use a value-type struct proxycfg.UpstreamID
as the map key in ConfigSnapshot maps where we used to use "upstream
id-ish" strings. These are internal only and used just for bidirectional
trips through the agent cache keyspace (like the discovery chain target
struct).
For the few places where the upstream id needs to be projected into xDS,
that's what (proxycfg.UpstreamID).EnvoyID() is for. This lets us ALWAYS
inject the partition and namespace into these things without making
stuff like the golden testdata diverge.
Remove some unnecessary comments around query_blocking metric. The only
line that needs any comments in the atomic decrement.
Cleanup the block and return comments and logic. The old comment about
AbandonCh may have been relevant before, but it is expected behaviour
now.
The logic was simplified by inverting the err condition.
This helps keep the logic in blockingQuery more focused. In the future we
may have a separate struct for RPC queries which may allow us to move this
off of Server.
This safeguard should be safe to apply in general. We are already
applying it to non-blocking queries that call blockingQuery, so it
should be fine to apply it to others.
To remove the TODO, and make it more readable.
In general this reduces the scope of variables, making them easier to reason about.
It also introduces more early returns so that we can see the flow from the structure
of the function.

`newIntermediate` is always equal to `needsNewIntermediate`, so we can
remove the extra variable and use the original directly.
Also remove the `activeRoot.ID != newActiveRoot.ID` case from an if,
because that case is already checked above, and `needsNewIntermediate` will
already be true in that case.
This condition now reads a lot better:
> Persist a new root if we did not have one before, or if generated a new intermediate.
In the previous commit the single use of this storedRoot was removed.
In this commit the original objective is completed. The
Provider.ActiveRoot is being removed because
1. the secondary should get the active root from the Consul primary DC,
not the provider, so that secondary DCs do not need to communicate
with a provider instance in a different DC.
2. so that the Provider.ActiveRoot interface can be changed without
impacting other code paths.
This method had only one caller, which always looked for the active
root. This commit moves the lookup into the method to reduce the logic
in the one caller.
This is being done in preparation for a larger change. Keeping this
separate so it is easier to see.
The `storedRootID != primaryRoots.ActiveRootID` is being removed because
these can never be different.
The `storedRootID` comes from `provider.ActiveRoot`, the
`primaryRoots.ActiveRootID` comes from the store `CARoot` from the
primary. In both cases the source of the data is the primary DC.
Technically they could be different if someone modified the provider
outside of Consul, but that would break many things, so is not a
supported flow.
If these were out of sync because of ordering of events then the
secondary will soon receive an update to `primaryRoots` and everything
will be sorted out again.
ActiveRoot should not be called from the secondary DC, because there
should not be a requirement to run the same Vault instance in a
secondary DC. SignIntermediate is called in a secondary DC, so it should
not call ActiveRoot
We would also like to change the interface of ActiveRoot so that we can
support using an intermediate cert as the primary CA in Consul. In
preparation for making that change I am reducing the number of calls to
ActiveRoot, so that there are fewer code paths to modify when the
interface changes.
This change required a change to the mockCAServerDelegate we use in
tests. It was returning the RootCert for SignIntermediate, but that is
not an accurate fake of production. In production this would also be a
separate cert.
Immediately above this line we are already appending the full list of
intermediates. The `provider.ActiveIntermediate` MUST be in this list of
intermediates because it must be available to all the other non-leader
Servers. If it was not in this list of intermediates then any proxy
that received data from a non-leader would have the wrong certs.
This is being removed now because we are planning on changing the
`Provider.ActiveIntermediate` interface, and removing these extra calls ahead of
time helps make that change easier.
Using tracing and cpu profiling I found that the majority of the time in
these test cases is spent generating a private key. We really don't need
separate private keys, so we can generate only one and use it for all
cases.
With this change the test runs much faster.
Fix the name to match the function it is testing
Remove unused code
Fix the signature, instead of returning (error, string) which should be (string, error)
accept a testing.T to emit errors.
Handle the error from encode.
Update the `/agent/check/deregister/` API endpoint to return a 404
HTTP response code when an attempt is made to de-register a check ID
that does not exist on the agent.
This brings the behavior of /agent/check/deregister/ in line with the
behavior of /agent/service/deregister/ which was changed in #10632 to
similarly return a 404 when de-registering non-existent services.
Fixes#5821
* clone the service under lock to avoid a data race
* add change log
* create a struct and copy the pointer to mutate it to avoid a data race
* fix failing test
* revert added space
* add comments, to clarify the data race.
The only function passed to SnapshotRPC today always returns a nil error, so there's no
way to exercise this bug in practice. This change is being made for correctness so that
it doesn't become a problem in the future, if we ever pass a different function to
SnapshotRPC.
Error messages related to service and check operations previously included
the following substrings:
- service %q
- check %q
From this error message, it isn't clear that the expected field is the ID for
the entity, not the name. For example, if the user has a service named test,
the error message would read 'Unknown service "test"'. This is misleading -
a service with that *name* does exist, but not with that *ID*.
The substrings above have been modified to make it clear that ID is needed,
not name:
- service with ID %q
- check with ID %q
Previously we could get into a state where discovery chain entries were
not cleaned up after the associated watch was cancelled. These changes
add handling for that case where stray chain references are encountered.
When a URL path is not found, return a non-empty message with the 404 status
code to help the user understand what went wrong. If the URL path was not
prefixed with '/v1/', suggest that may be the cause of the problem (which is a
common mistake).

This query has been incorrectly querying by accessor ID since New ACLs
were added. However, the legacy token compat allowed this to continue to
work, since it made a fallback query for the anonymousToken ID.
PR #11184 removed this legacy token query, which means that the query by
accessor ID is now the only check for the anonymous token's existence.
This PR updates the GetBySecret call to use the secret ID of the token.
These helper functions actually end up hiding important setup details
that should be visible from the test case. We already have a convenient
way of setting this config when calling newTestServerWithConfig.
I suspect one problem was that we set structs.IntermediateCertRenewInterval to 1ms, which meant
that in some cases the intermediate could renew before we stored the original value.
Another problem was that the 'wait for intermediate' loop was calling the provider.ActiveIntermediate,
but the comparison needs to use the RPC endpoint to accurately represent a user request. So
changing the 'wait for' to use the state store ensures we don't race.
Also moves the patching into a separate function.
Removes the addition of ca.CertificateTimeDriftBuffer as part of calculating halfTime. This was added
in a previous commit to attempt to fix the flake, but it did not appear to fix the problem. Adding the
time here was making the tests fail when using the shared patch
function. It's not clear to me why, but there's no reason we should be
including this time in the halfTime calculation.
Use the new verifyLearfCert to show the cert verifies with intermediates
from both sources. This required using the RPC interface so that the
leaf pem was constructed correctly.
Add IndexedCARoots.Active since that is a common operation we see in a
few places.
Previously we had a couple copies that reproduced the FSM operation.
These copies introduce risk that the test does not accurately match
production.
This PR removes the test versions of the FSM operation, and exports the
real production FSM operation so that it can be used in tests.
The consul provider tests did need to change because of this. Previously
we would return a hardcoded value of 2, but in production this value is
always incremented.
Failing over to a partition is more siimilar to failing over to another
datacenter than it is to failing over to a namespace. In a future
release we should update how localities for failover are specified. We
should be able to accept a list of localities which can include both
partition and datacenter.
* Add partition fields to targets like service route destinations
* Update validation to prevent cross-DC + cross-partition references
* Handle partitions when reading config entries for disco chain
* Encode partition in compiled targets
Fixes a bug whereby servers present in multiple network areas would be
properly segmented in the Router, but not in the gRPC mirror. This would
lead servers in the current datacenter leaving from a network area
(possibly during the network area's removal) from deleting their own
records that still exist in the standard WAN area.
The gRPC client stack uses the gRPC server tracker to execute all RPCs,
even those targeting members of the current datacenter (which is unlike
the net/rpc stack which has a bypass mechanism).
This would manifest as a gRPC method call never opening a socket because
it would block forever waiting for the current datacenter's pool of
servers to be non-empty.
Given that we do not allow wildcard partitions in intentions, no one ixn
can override the DefaultAllow setting. Only the default ACL policy
applies across all partitions.
This table purposefully does not index by partition/namespace. It's a
global view into all service names.
This table is intended to replace the current serviceListTxn watch in
intentionTopologyTxn. For cross-partition transparent proxying we need
to be able to calculate upstreams from intentions in any partition. This
means that the existing serviceListTxn function is insufficient since
it's scoped to a partition.
Moving away from that function is also beneficial because it watches the
main "services" table, so watchers will wake up when any instance is
registered or deregistered.
