This commit removes the actingSecondaryCA field, and removes the stateLock around it. This field
was acting as a proxy for providerRoot != nil, so replace it with that check instead.
The two methods which called secondarySetCAConfigured already set the state, so checking the
state again at this point will not catch runtime errors (only programming errors, which we can catch with tests).
In general, handling state transitions should be done on the "entrypoint" methods where execution starts, not
in every internal method.
This is being done to remove some unnecessary references to c.state, in preparations for extracting
types for primary/secondary.
This makes it easier to fake, which will allow me to use the ConsulProvider as
an 'external PKI' to test a customer setup where the actual root CA is not
the root we use for the Consul CA.
Replaces a call to the state store to fetch the clusterID with the
clusterID field already available on the built-in provider.

The TrustDomain is populated from the Host() method which includes the
hard-coded "consul" domain. This means that despite having an empty
cluster ID, the TrustDomain won't be empty.
There are two restrictions:
- Writes from the primary DC which explicitly target a secondary DC.
- Writes to a secondary DC that do not explicitly target the primary DC.
The first restriction is because the config entry is not supported in
secondary datacenters.
The second restriction is to prevent the scenario where a user writes
the config entry to a secondary DC, the write gets forwarded to the
primary, but then the config entry does not apply in the secondary.
This makes the scope more explicit.
Currently getCARoots could return an empty object with an empty trust
domain before the CA is initialized. This commit returns an error while
there is no CA config or no trust domain.
There could be a CA config and no trust domain because the CA config can
be created in InitializeCA before initialization succeeds.

Previously secondaryInitialize would return nil in this case, which prevented the
deferred initialize from happening, and left the CA in an uninitialized state until a config
update or root rotation.
To fix this I extracted the common parts into the delegate implementation. However looking at this
again, it seems like the handling in secondaryUpdateRoots is impossible, because that function
should never be called before the secondary is initialzied. I beleive we can remove some of that
logic in a follow up.

These labels should be set by whatever process scrapes Consul (for
prometheus), or by the agent that receives them (for datadog/statsd).
We need to remove them here because the labels are part of the "metric
key", so we'd have to pre-declare the metrics with the labels. We could
do that, but that is extra work for labels that should be added from
elsewhere.
Also renames the closure to be more descriptive.
Prometheus scrapes metrics from each process, so when leadership transfers to a different node
the previous leader would still be reporting the old cached value.
By setting NaN, I believe we should zero-out the value, so that prometheus should only consider the
value from the new leader.
Emit the metric immediately so that after restarting an agent, the new expiry time will be
emitted. This is particularly important when this metric is being monitored, because we want
the alert to resovle itself immediately.
Also fixed a bug that was exposed in one of these metrics. The CARoot can be nil, so we have
to handle that case.
TestSubscribeBackend_IntegrationWithServer_DeliversAllMessages has been
flaking a few times. This commit cleans up the test a bit, and improves
the failure output.
I don't believe this actually fixes the flake, but I'm not able to
reproduce it reliably.
The failure appears to be that the event with Port=0 is being sent in
both the snapshot and as the first event after the EndOfSnapshot event.
Hopefully the improved logging will show us if these are really
duplicate events, or actually different events with different indexes.
partitionAuthorizer.config can be nil if it wasn't provided on calls to
newPartitionAuthorizer outside of the ACLResolver. This usage happens
often in tests.
This commit: adds a nil check when the config is going to be used,
updates non-test usage of NewPolicyAuthorizerWithDefaults to pass a
non-nil config, and dettaches setEnterpriseConf from the ACLResolver.
When issuing cross-partition service discovery requests, ACL filtering
often checks for NodeRead privileges. This is because the common return
type is a CheckServiceNode, which contains node data.
useInDatacenter was used to determine whether the mesh gateway mode of
the upstream should be returned in the discovery chain target. This
commit makes it so that the mesh gateway mode is returned every time,
and it is up to the caller to decide whether mesh gateways should be
watched or used.
Existing config entries prefixed by service- are specific to individual
services. Since this config entry applies to partitions it is being
renamed.
Additionally, the Partition label was changed to Name because using
Partition at the top-level and in the enterprise meta was leading to the
enterprise meta partition being dropped by msgpack.
The code for this was already removed, which suggests this is not actually testing what it claims.
I'm guessing these are still resolving because the tokens are converted to non-legacy tokens?
It seems like this was missing. Previously this was only called by init of ACLs during an upgrade.
Now that legacy ACLs are removed, nothing was calling stop.
Also remove an unused method from client.
This function is only run when the CAManager is a primary. Extracting this function
makes it clear which parts of UpdateConfiguration are run only in the primary and
also makes the cleanup logic simpler. Instead of both a defer and a local var we
can call the cleanup function in two places.
This commit renames functions to use a consistent pattern for identifying the functions that
can only be called when the Manager is run as the primary or secondary.
This is a step toward eventually creating separate types and moving these methods off of CAManager.

This commit two test failures:
1. Remove check for "in legacy ACL mode", the actual upgrade will be removed in a following commit.
2. Remove the early WaitForLeader in dc2, because with it the test was
failing with ACL not found.
TestAgentLeaks_Server was reporting a goroutine leak without this. Not sure if it would actually
be a leak in production or if this is due to the test setup, but seems easy enough to call it
this way until we remove legacyACLTokenUpgrade.
We no long need to read the acl serf tag, because servers are always either ACL enabled or
ACL disabled.
We continue to write the tag so that during an upgarde older servers will see the tag.
This commit two test failures:
1. Remove check for "in legacy ACL mode", the actual upgrade will be removed in a following commit.
2. Use the root token in WaitForLeader, because without it the test was
failing with ACL not found.
As part of removing the legacy ACL system ACL upgrading and the flag for
legacy ACLs is removed from Clients.
This commit also removes the 'acls' serf tag from client nodes. The tag is only ever read
from server nodes.
This commit also introduces a constant for the acl serf tag, to make it easier to track where
it is used.
Replace it with an implementation that returns an error, and rename some symbols
to use a Deprecated suffix to make it clear.
Also remove the ACLRequest struct, which is no longer referenced.
When converting these tests from the legacy ACL system to the new RPC endpoints I
initially changed most things to use _prefix rules, because that was equivalent to
the old legacy rules.
This commit modifies a few of those rules to be a bit more specific by replacing the _prefix
rule with a non-prefix one where possible.
In preparation for removing ACL.Apply.
Tests for ACL.Apply, ACL.GetPolicy, and ACL upgrades were removed
because all 3 of those will be removed shortly.
The forth test appears to be for the ACLResolver cache, so the test was moved to the correct
test file, and the name was updated to make it obvious what is being tested.
structs.ACLForceSet was deprecated 4 years ago, it should be safe to remove now.
ACLBootstrapNow was removed in a recent commit. While it is technically possible that a cluster with mixed version
could still attempt a legacy boostrap, we documented that the legacy system was deprecated in 1.4, so no
clusters that are being upgraded should be attempting a legacy boostrap.

Some users are defining routing configurations that do not have associated services. This commit surfaces these configs in the topology visualization. Also fixes a minor internal bug with non-transparent proxy upstream/downstream references.

Remove the error return, so that not handling is not reported as an
error by errcheck. It was returning the error passed as an arg
unmodified so there is no reason to return the same value that was
passed in.
Remove the term upstreams to remove any confusion with the term used in
service mesh.
Remove the AutoDisable field, and replace it with the TTL value, using 0
to indicate the setting is turned off.
Replace "not Before" with "After".
Add some test coverage to show the behaviour is still correct.
This field was never user-configurable. We always overwrote the value with 120s from
NonUserSource. However, we also never copied the value from RuntimeConfig to consul.Config,
So the value in NonUserSource was always ignored, and we used the default value of 30s
set by consul.DefaultConfig.
All of this code is an unnecessary distraction because a user can not actually configure
this value.
This commit removes the fields and uses a constant value instad. Someone attempting to set
acl.disabled_ttl in their config will now get an error about an unknown field, but previously
the value was completely ignored, so the new behaviour seems more correct.
We have to keep this field in the AutoConfig response for backwards compatibility, but the value
will be ignored by the client, so it doesn't really matter what value we set.
Tests only specified one of the fields, but in production we copy the
value from a single place, so we can do the same in tests.
The AutoConfig test broke because of the problem noticed in a previous
commit. The DisabledTTL is not wired up properly so it reports 0s here.
Changed the test to use an explicit value.
Follow up to https://github.com/hashicorp/consul/pull/10737#discussion_r682147950
Renames all variables for acl.Authorizer to use `authz`. Previously some
places used `rule` which I believe was an old name carried over from the
legacy ACL system.
A couple places also used authorizer.
This commit also removes another couple of authorizer nil checks that
are no longer necessary.
The constructor for Server is not at all the appropriate place to be setting default
values for a config struct that was passed in.
In production this value is always set from agent/config. In tests we should set the
default in a test helper.
This field has been unnecessary for a while now. It was always set to the same value
as PrimaryDatacenter. So we can remove the duplicate field and use PrimaryDatacenter
directly.
This change was made by GoLand refactor, which did most of the work for me.
This method suffered from similar naming to a couple other methods on Server, and had not great
re-use (2 callers). By copying a few of the lines into one of the callers we can move the
implementation into the second caller.
Once moved, we can see that ResolveTokenAndDefaultMeta is identical in both Client and Server, and
likely should be further refactored, possibly into ACLResolver.
This change is being made to make ACL resolution easier to trace.
This method was an alias for ACLResolver.ResolveTokenToIdentityAndAuthorizer. By removing the
method that does nothing the code becomes easier to trace.
ACL filtering only needs an authorizer and a logger. We can decouple filtering from
the ACLResolver by passing in the necessary logger.
This change is being made in preparation for moving the ACLResolver into an acl package
filterACLWithAuthorizer could never return an error. This change moves us a little bit
closer to being able to enable errcheck and catch problems caused by unhandled error
return values.
These functions are moved to the one place they are called to improve code locality.
They are being moved out of agent/consul/acl.go in preparation for moving
ACLResolver to an acl package.
These functions are used in only one place. Move the functions next to their one caller
to improve code locality.
This change is being made in preparation for moving the ACLResolver into an
acl package. The moved functions were previously in the same file as the ACLResolver.
By moving them out of that file we may be able to move the entire file
with fewer modifications.

Previously we were passing an Authorizer that would always allow the
operation, then later checking the authorization using vetServiceTxnOp.
On the surface this seemed strange, but I think it was actually masking
a bug as well. Over time `servicePreApply` was changed to add additional
authorization for `service.Proxy.DestinationServiceName`, but because
we were passing a nil Authorizer, that authorization was not handled on
the txn_endpoint.
`TxnServiceOp.FillAuthzContext` has some special handling in enterprise,
so we need to make sure to continue to use that from the Txn endpoint.
This commit removes the `vetServiceTxnOp` function, and passes in the
`FillAuthzContext` function so that `servicePreApply` can be used by
both the catalog and txn endpoints. This should be much less error prone
and prevent bugs like this in the future.

These checks were a bit more involved. They were previously skipping some code paths
when the authorizer was nil. After looking through these it seems correct to remove the
authz == nil check, since it will never evaluate to true.
These case are already impossible conditions, because most of these functions already start
with a check for ACLs being disabled. So the code path being removed could never be reached.
The one other case (ConnectAuthorized) was already changed in a previous commit. This commit
removes an impossible branch because authz == nil can never be true.

A previous commit used SetHash on two of the cases to fix a data race. This commit applies
that change to all cases. Using SetHash in this test helper should ensure that the
test helper behaves closer to production.
Some global variables are patched to shorter values in these tests. But the goroutines that read
them can outlive the test because nothing waited for them to exit.
This commit adds a Wait() method to the routine manager, so that tests can wait for the goroutines
to exit. This prevents the data race because the 'reset to original value' can happen
after all other goroutines have stopped.

raftApply was removed so ApplyCARequest needs to handle all the possible operations
Also set the providerShim to use the mock provider.
other changes are small test improvements that were necessary to debug the failures.
and small refactor to getCAProvider so that GoLand is less confused about what it is doing.
Previously it was reporting that the for condition was always true, which was not the case.
After moving ca.ConsulProviderStateDelegate into the interface we now
have the ApplyCARequest method which does the same thing. Use this more
specific method instead of raftApply.
This field was documented as enabling TLS for outgoing RPC, but that was not the case.
All this field did was set the use_tls serf tag.
Instead of setting this field in a place far from where it is used, move the logic to where
the serf tag is set, so that the code is much more obvious.
tlsutil.Config already presents an excellent structure for this
configuration. Copying the runtime config fields to agent/consul.Config
makes code harder to trace, and provides no advantage.
Instead of copying the fields around, use the tlsutil.Config struct
directly instead.
This is one small step in removing the many layers of duplicate
configuration.

The query metrics are actually reported for all read queries, not only
ones that use a MinIndex to block for updates.
Also clarify the raft.apply metric is only on the leader.
As part of this change, we ensure that the SAN extensions are marked as
critical when the subject is empty so that AWS PCA tolerates the loss of
common names well and continues to function as a Connect CA provider.
Parts of this currently hack around a bug in crypto/x509 and can be
removed after https://go-review.googlesource.com/c/go/+/329129 lands in
a Go release.
Note: the AWS PCA tests do not run automatically, but the following
passed locally for me:
ENABLE_AWS_PCA_TESTS=1 go test ./agent/connect/ca -run TestAWS
With an optional interface that providers can use to indicate if they
use an intermediate cert in the primary DC.
This removes the need to look up the provider config when renewing the
intermediate.
CatalogDestinationsOnly is a passthrough that would enable dialing
addresses outside of Consul's catalog. However, when this flag is set to
true only _connect_ endpoints for services can be dialed.
This flag is being renamed to signal that non-Connect endpoints can't be
dialed by transparent proxies when the value is set to true.
Both NextLink and NextNoBlock had the same logic, with slightly
different return values. By adding a bool return value (similar to map
lookups) we can remove the duplicate method.
The head of the topic buffer was being ignored when creating a snapshot. This commit fixes
the bug by ensuring that the head of the topic buffer is included in the snapshot
before handing it off to the subscription.
This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.
Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.
We have seen test flakes caused by 'concurrent map read and map write', and the race detector
reports the problem as well (prevent us from running some tests with -race).
The root of the problem is the grpc expects resolvers to be registered at init time
before any requests are made, but we were using a separate resolver for each test.
This commit introduces a resolver registry. The registry is registered as the single
resolver for the consul scheme. Each test uses the Authority section of the target
(instead of the scheme) to identify the resolver that should be used for the test.
The scheme is used for lookup, which is why it can no longer be used as the unique
key.
This allows us to use a lock around the map of resolvers, preventing the data race.
The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.
This refactor is to make it easier to see how serf feature flags are
encoded as serf tags, and where those feature flags are read.
- use constants for both the prefix and feature flag name. A constant
makes it much easier for an IDE to locate the read and write location.
- isolate the feature-flag encoding logic in the metadata package, so
that the feature flag prefix can be unexported. Only expose a function
for encoding the flags into tags. This logic is now next to the logic
which reads the tags.
- remove the duplicate `addEnterpriseSerfTags` functions. Both Client
and Server structs had the same implementation. And neither
implementation needed the method receiver.
The prior solution to call reply.Reset() aged poorly since newer fields
were added to the reply, but not added to Reset() leading serial
blocking query loops on the server to blend replies.
This could manifest as a service-defaults protocol change from
default=>http not reverting back to default after the config entry
reponsible was deleted.
TestACLEndpoint_Login_with_TokenLocality was reguardly being reported as failed even though
it was not failing. I took another look and I suspect it is because t.Parllel was being
called in a goroutine.
This would lead to strange behaviour which apparently confused the 'go test' runner.
Also accept an RPCInfo instead of interface{}. Accepting an interface
lead to a bug where the caller was expecting the arg to be the response
when in fact it was always passed the request. By accepting RPCInfo
it should indicate that this is actually the request value.
One caller of canRetry already passed an RPCInfo, the second handles
the type assertion before calling canRetry.
Also fixes a bug with listing kind=mesh config entries. ValidateConfigEntryKind was only being used by
the List endpoint, and was yet another place where we have to enumerate all the kinds.
This commit removes ValidateConfigEntryKind and uses MakeConfigEntry instead. This change removes
the need to maintain two separate functions at the cost of creating an instance of the config entry which will be thrown away immediately.

* Give descriptive error if auth method not found
Previously during a `consul login -method=blah`, if the auth method was not found, the
error returned would be "ACL not found". This is potentially confusing
because there may be many different ACLs involved in a login: the ACL of
the Consul client, perhaps the binding rule or the auth method.
Now the error will be "auth method blah not found", which is much easier
to debug.
No config entry needs a Kind field. It is only used to determine the Go type to
target. As we introduce new config entries (like this one) we can remove the kind field
and have the GetKind method return the single supported value.
In this case (similar to proxy-defaults) the Name field is also unnecessary. We always
use the same value. So we can omit the name field entirely.
This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.
Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.
Previously canRetry was attempting to retrieve this error from args, however there was never
any callers that would pass an error to args.
With the change to raftApply to move this error to the error return value, it is now possible
to receive this error from the err argument.
This commit updates canRetry to check for ErrChunkingResubmit in err.
Previously we were inconsistently checking the response for errors. This
PR moves the response-is-error check into raftApply, so that all callers
can look at only the error response, instead of having to know that
errors could come from two places.
This should expose a few more errors that were previously hidden because
in some calls to raftApply we were ignoring the response return value.
Also handle errors more consistently. In some cases we would log the
error before returning it. This can be very confusing because it can
result in the same error being logged multiple times. Instead return
a wrapped error.
Previously only a single auth method would be saved to the snapshot. This commit fixes the typo
and adds to the test, to show that all auth methods are now saved.
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:
- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.
This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.
This is needed in case the client proxy is in TransparentProxy mode.
Typically they won't have explicit configuration for every upstream, so
this ensures the settings can be applied to all of them when generating
xDS config.
New clients in transparent proxy mode can send requests for service
config resolution without any upstream args because they do not have
explicitly defined upstreams.
Old clients on the other hand will never send requests without the
Upstreams args unless they don't have upstreams, in which case we do not
send back upstream config.
As part of this change the indexer will now be case insensitive by using
the lower case value. This should be safe because previously we always
had lower case strings.
This change was made out of convenience. All the other indexers use
lowercase, so we can re-use the indexFromQuery function by using
lowercase here as well.
Previously we were encoding the UUID as a string, but the index it references uses a UUID
so this index can also use an encoded UUID to save a bit of memory.
Prefix queries are generally being used to match part of a partial
index. We can support these indexes by using a function that accept
different types for each subset of the index.
What I found interesting is that in the generic StringFieldIndexer the
implementation for PrefixFromArgs would remove the trailing null, but
at least in these 2 cases we actually want a null terminated string.
We simply want fewer components in the string.
The TestServiceHealthEventsFromChanges function was over 1400 lines.
Attempting to debug test failures in test functions this large is
difficult. It requires scrolling to the line which defines the testcase
because the failure message only includes the line number of the
assertion, not the line number of the test case.
This is an excellent example of where test tables stop working well, and
start being a problem. To mitigate this problem, the runCase pattern can
be used. When one of these tests fails, a failure message will print the
line number of both the test case and the assertion. This allows a
developer to quickly jump to both of the relevant lines, signficanting
reducing the time it takes to debug test failures.
For example, one such failure could look like this:
catalog_events_test.go:1610: case: service reg, new node
catalog_events_test.go:1605: assertion failed: values are not equal
ResolveServiceConfig is called by service manager before the proxy
registration is in the catalog. Therefore we should pass proxy
registration flags in the request rather than trying to fetch
them from the state store (where they may not exist yet).
This is done because after removing ID and NodeName from
ServiceConfigRequest we will no longer know whether a request coming in
is for a Consul client earlier than v1.10.
This enables it to be called for many upstreams or downstreams of a
service while only querying intentions once.
Additionally, decisions are now optionally denied due to L7 permissions
being present. This enables the function to be used to filter for
potential upstreams/downstreams of a service.
Previously this type was defined in structs, but unlike the other types in structs this type
is not used by RPC requests. By moving it to state we can better indicate that this is not
an API type, but part of the state implementation.
I added this recently without realizing that the method already existed and was named
NamespaceOrEmpty. Replace all calls to GetNamespace with NamespaceOrEmpty or NamespaceOrDefault
as appropriate.
Document that this comparison should roughly match MatchesKey
Only sort by overrideKey or service name, but not both
Add namespace to the sort.
The client side also builds a map of these based on the namespace/node/service key, so the only order
that really matters is the ordering of register/dereigster events.
Refactored out a function that can be used for both the snapshot and stream of events to translate
an event into an appropriate connect event.
Previously terminating gateway events would have used the wrong key in the snapshot, which would have
caused them to be filtered out later on.
Also removed an unused function, and some commented out code.

These new functional indexers provide a few advantages:
1. enterprise differences can be isolated to a single function (the
indexer function), making code easier to change
2. as a consequence of (1) we no longer need to wrap all the calls to
Txn operations, making code easier to read.
3. by removing reflection we should increase the performance of all
operations.
One important change is in making all the function signatures the same.
https://blog.golang.org/errors-are-values
An extra boolean return value for SingleIndexer.FromObject is superfluous.
The error value can indicate when the index value could not be created.
By removing this extra return value we can use the same signature for both
indexer functions.
This has the nice properly of a function being usable for both indexing operations.
By using a new pattern for more specific indexes. This allows us to use
the same index for both service checks and node checks. It removes the
abstraction around memdb.Txn operations, and isolates all of the
enterprise differences in a single place (the indexer).
Previously a snapshot created as part of a resumse-stream request could have incorrectly
cached the newSnapshotToFollow event. This would cause clients to error because they
received an unexpected framing event.
This fixes an issue where leaf certificates issued in primary
datacenters using Vault as a Connect CA would be reissued very
frequently (every ~20 seconds) because the logic meant to detect root
rotation was errantly triggering.
The hash of the rootCA was being compared against a hash of the
intermediateCA and always failing. This doesn't apply to the Consul
built-in CA provider because there is no intermediate in use in the
primary DC.
This is reminiscent of #6513
registerSchema creates some indirection which is not necessary in this
case. newDBSchema can call each of the tables.
Enterprise tables can be added from the existing withEnterpriseSchema
shim.
This allows setting ForceWithoutCrossSigning when reconfiguring the CA
for any provider, in order to forcibly move to a new root in cases where
the old provider isn't reachable or able to cross-sign for whatever
reason.
This way we only have to wait for the serf barrier to pass once before
we can make use of federation state APIs Without this patch every
restart needs to re-compute the change.
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.
* 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.
