When subscriptions are too slow to accept messages on their channels,
then we should remove them from the fanout so that we don't have
dead subscriptions using up resources.
In addition, when a subscription is explicitly canceled, we should
also clean up after it remove the corresponding pipeline.
We also add a new metrics, `events.subscriptions`, to keep track
of the number of active subscriptions. This also helps us test.

This checks the request against the `read` permission for
`sys/events/subscribe/{eventType}` on the initial subscribe.
Future work includes moving this to its own verb (`subscribe`)
and periodically rechecking the request.
Tested locally by minting a token with the wrong permissions
and verifying that they are rejected as expected, and that
they work if the policy is adjusted to `sys/event/subscribe/*`
(or the specific topic name) with `read` permissions.
I had to change the `core.checkToken()` to be publicly accessible,
as it seems like the easiest way to check the token on the
`logical.Request` against all relevant policies, but without
going into all of the complex logic further in `handleLogical()`.

Also updates the event receieved to include a timestamp.
Websockets support both JSON and protobuf binary formats.
This can be used by either `wscat` or the new
`vault events subscribe`:
e.g.,
```sh
$ wscat -H "X-Vault-Token: $(vault print token)" --connect ws://127.0.0.1:8200/v1/sys/events/subscribe/abc?json=true
{"event":{"id":"5c5c8c83-bf43-7da5-fe88-fc3cac814b2e", "note":"testing"}, "eventType":"abc", "timestamp":"2023-02-07T18:40:50.598408Z"}
...
```
and
```sh
$ vault events subscribe abc
{"event":{"id":"5c5c8c83-bf43-7da5-fe88-fc3cac814b2e", "note":"testing"}, "eventType":"abc", "timestamp":"2023-02-07T18:40:50.598408Z"}

* Add global, cross-cluster revocation queue to PKI
This adds a global, cross-cluster replicated revocation queue, allowing
operators to revoke certificates by serial number across any cluster. We
don't support revoking with private key (PoP) in the initial
implementation.
In particular, building on the PBPWF work, we add a special storage
location for handling non-local revocations which gets replicated up to
the active, primary cluster node and back down to all secondary PR
clusters. These then check the pending revocation entry and revoke the
serial locally if it exists, writing a cross-cluster confirmation entry.
Listing capabilities are present under pki/certs/revocation-queue,
allowing operators to see which certs are present. However, a future
improvement to the tidy subsystem will allow automatic cleanup of stale
entries.

* Allow tidying revocation queue entries
No manual operator control of revocation queue entries are allowed.
However, entries are stored with their request time, allowing tidy to,
after a suitable safety buffer, remove these unconfirmed and presumably
invalid requests.
Notably, when a cluster goes offline, it will be unable to process
cross-cluster revocations for certificates it holds. If tidy runs,
potentially valid revocations may be removed. However, it is up to the
administrator to ensure the tidy window is sufficiently long that any
required maintenance is done (or, prior to maintenance when an issue is
first noticed, tidy is temporarily disabled).

* Use a locking queue to handle revocation requests
This queue attempts to guarantee that PKI's invalidateFunc won't have

waiting for queue accesses.
Previously, we held a lock during tidy and processing that would've
prevented us from processing invalidateFunc calls.

For example, using:
```sh

Also added a small fix to pass the `hclog.Logger` in now so that
the logging hierarchy and levels are respected.
* OpenAPI `generic_mount_paths` follow-up
An incremental improvement within larger context discussed in #18560.
* Following the revert in #18617, re-introduce the change from
`{mountPath}` to `{<path-of-mount>_mount_path}`; this is needed, as
otherwise paths from multiple plugins would clash - e.g. almost every
auth method would provide a conflicting definition for
`auth/{mountPath}/login`, and the last one written into the map would
win.
* Move the half of the functionality that was in `sdk/framework/` to
`vault/logical_system.go` with the rest; this is needed, as
`sdk/framework/` gets compiled in to externally built plugins, and
therefore there may be version skew between it and the Vault main
code. Implementing the `generic_mount_paths` feature entirely on one
side of this boundary frees us from problems caused by this.
* Update the special exception that recognizes `system` and `identity`
as singleton mounts to also include the other two singleton mounts,
`cubbyhole` and `auth/token`.
* Include a comment that documents to restricted circumstances in which
the `generic_mount_paths` option makes sense to use:
// Note that for this to actually be useful, you have to be using it with
// a Vault instance in which you have mounted one of each secrets engine
// and auth method of types you are interested in, at paths which identify
// their type, and for the KV secrets engine you will probably want to
// mount separate kv-v1 and kv-v2 mounts to include the documentation for
// each of those APIs.
* Fix tests

added 4 years ago in #5687 - the implied update has not happened.
* Add changelog
* Update 18663.txt

Create global quotas of each type in every NewTestCluster. Also switch some key locks to use DeadlockMutex to make it easier to discover deadlocks in testing.
NewTestCluster also now starts the cluster, and the Start method becomes a no-op. Unless SkipInit is provided, we also wait for a node to become active, eliminating the need for WaitForActiveNode. This was needed because otherwise we can't safely make the quota api call. We can't do it in Start because Start doesn't return an error, and I didn't want to begin storing the testing object T instead TestCluster just so we could call t.Fatal inside Start.
The last change here was to address the problem of how to skip setting up quotas when creating a cluster with a nonstandard handler that might not even implement the quotas endpoint. The challenge is that because we were taking a func pointer to generate the real handler func, we didn't have any way to compare that func pointer to the standard handler-generating func http.Handler without creating a circular dependency between packages vault and http. The solution was to pass a method instead of an anonymous func pointer so that we can do reflection on it.

* Removes _builtin_ versions from mount storage where it already exists

* Stops the plugin catalog from returning a builtin plugin that has been overridden, so it more accurately reflects the plugins that are available to actually run
This commit adds some logic to handle the case where a mount entry has a
non-builtin RunningVersion. This ensures that we only report deprecation
status for builtins.
The current behaviour is to only add mount paths into the generated `opeanpi.json` spec if a `generic_mount_paths` flag is added to the request. This means that we would have to maintain two different `openapi.json` files, which is not ideal. The new solution in this PR is to add `{mount_path}` into every path with a default value specified:
```diff
-- "/auth/token/accessors/": {
++ "/auth/{mount_path}/accessors/": {
"parameters": [
{
"name": "mount_path",
"description": "....",
"in": "path",
"schema": {
"type": "string",
++ "default": "token"
}
}
],
```
Additionally, fixed the logic to generate the `operationId` (used to generate method names in the code generated from OpenAPI spec). It had a bug where the ID had `mountPath` in it. The new ID will look like this:
```diff
-- "operationId": "listAuthMountpathAccessors",
++ "operationId": "listTokenAccessors",
```

Add some metrics helpful for monitoring raft cluster state.
Furthermore, we weren't emitting bolt metrics on regular (non-perf) standbys, and there were other metrics
in metricsLoop that would make sense to include in OSS but weren't. We now have an active-node-only func,
emitMetricsActiveNode. This runs metricsLoop on the active node. Standbys and perf-standbys run metricsLoop
from a goroutine managed by the runStandby rungroup.
We are specifically checking that the writes are now allowed for group
and other.
I don't know how this test was passing on non-arm64 platforms,
but hopefully this should fix it.
This commit refactors the `persistAudit`, `persistAuth`, and `persistMount` code paths to perform `entry.Table` type-checking within the same loop as the entry list appending. This saves cycles in the case of success; however, performs some unnecessary appends in the event that an entry has an incorrect table type/value combination.
Ensure that we don't try to access Core.perfStandby or Core.PerfStandby() from dynamicSystemView, which might be accessed with or without stateLock held.
Change the multiplexing key to use all `PluginRunner` config (converted to a struct which is comparable), so that plugins with the same name but different env, args, types, versions etc are not incorrectly multiplexed together.

Builtin plugins cannot be overridden in mounts
Before versioning, plugins with the same names as builtins (e.g., "kv")
could be registered, but trying to mount them would always use the
builtin versions.
With versioning, we still allow registering plugins with the same name
as a builtin. However, if the user tries to mount a versioned plugin
with the same name as a builtin, and specifies the non-builtin version
be used, we return an error.
Otherwise the user would see a confusing situation where the one or
both of the Version and RunningVersion would say they were using
the user-requested version, but in reality were using the builtin
version.

Check if plugin version matches running version
When registering a plugin, we check if the request version matches the
self-reported version from the plugin. If these do not match, we log a
warning.
This uncovered a few missing pieces for getting the database version
code fully working.
We added an environment variable that helps us unit test the running
version behavior as well, but only for approle, postgresql, and consul
plugins.
Return 400 on plugin not found or version mismatch
Populate the running SHA256 of plugins in the mount and auth tables (#17217)
Break grabLockOrStop into two pieces to facilitate investigating deadlocks. Without this change, the "grab" goroutine looks the same regardless of who was calling grabLockOrStop, so there's no way to identify one of the deadlock parties.
Factored out some plugin related tests into their own test package, and added a bunch of parallelism. Moved some non-plugin tests that were in logical_system_integ_test into another file (keeping them in vault package) just for cohesion.
Add plugin version to GRPC interface
Added a version interface in the sdk/logical so that it can be shared between all plugin types, and then wired it up to RunningVersion in the mounts, auth list, and database systems.
I've tested that this works with auth, database, and secrets plugin types, with the following logic to populate RunningVersion:
If a plugin has a PluginVersion() method implemented, then that is used
If not, and the plugin is built into the Vault binary, then the go.mod version is used
Otherwise, the it will be the empty string.
My apologies for the length of this PR.
* Placeholder backend should be external
We use a placeholder backend (previously a framework.Backend) before a
GRPC plugin is lazy-loaded. This makes us later think the plugin is a
builtin plugin.
So we added a `placeholderBackend` type that overrides the
`IsExternal()` method so that later we know that the plugin is external,
and don't give it a default builtin version.
