Biggest change: we rename `Send` to `SendEvent` in `logical.EventSender`..
Initially we picked `Send` to match the underlying go-eventlogger
broker's `Send` method, and to avoid the stuttering of `events.SendEvent`.
However, I think it is more useful for the `logical.EventSender`
interface to use the method `SendEvent` so that, for example,
`framework.Backend` can implement it.
This is a relatively change now that should not affect anything
except the KV plugin, which is being fixed in another PR.
Another change: if the `secret_path` metadata is present, then
the plugin-aware `EventBus` will prepend it with the plugin mount.
This allows the `secret_path` to be the full path to any referenced
secret.
This change is also backwards compatible, since this field was not
present in the KV plugin. (It did use the slightly different `path`
field, which we can keep for now.)
In my recent #21942, I overlooked the need to sort another part of the
OpenAPI document to ensure stable output.
I've also removed `strings.ToLower()` from the code I copied from, as
this code is sorting Vault API parameter names, which are all lowercase
anyway!
* OpenAPI: Define default response structure for ListOperations

* OpenAPI: Fix generation of correct fields
Currently, the OpenAPI generator logic is wrong about how it maps from
Vault framework fields to OpenAPI. This manifests most obviously with
endpoints making use of `framework.OptionalParamRegex` or similar
regex-level optional path parameters, and results in various incorrect
fields showing up in the generated request structures.
The fix is a bit complicated, but in essence is just rewriting the
OpenAPI logic to properly parallel the real request processing logic.
With these changes:
* A path parameter in an optional part of the regex, no longer gets
erroneously treated as a body parameter when creating OpenAPI
endpoints that do not include the optional parameter.
* A field marked as `Query: true` no longer gets incorrectly skipped
when creating OpenAPI `POST` operations.
* changelog
* Add missing `Query: true` metadata to API definitions
Also improve the documentation comment for `Query` to guide people better how they should be setting `Query` in the future.
Endpoints affected:
- auth/approle/role/{role_name}/secret-id/destroy
- auth/approle/role/{role_name}/secret-id-accessor/destroy
- auth/token/lookup
- auth/token/lookup-self
- sys/internal/specs/openapi
- sys/wrapping/lookup
- identity/oidc/provider/{name}/authorize
There are also endpoints in the `aws` and `gcp` secrets engines which need the same treatment in their own PRs.
When working on the `auth/token/lookup-self` path, I discovered that it
had a parameter which was completely pointless - it was even documented
as unused. It only existed because the `auth/token/lookup-self` code
path was implemented by bodging the current token into the request data
and passing control to the `auth/token/lookup` handler directly -
instead of just factoring out the common code to a reusable function -
so I fixed that whilst I was there.
Note that two of the affected endpoints currently have one form of their
OpenAPI operation ID set to something mentioning "with-parameters":
- identity/oidc/provider/{name}/authorize
- sys/internal/specs/openapi
These operation IDs should be changed, as they perpetuate
a misunderstanding - both read (GET) and update (POST/PUT) forms of
these APIs are **equally** capable of being used with parameters.
* I failed to spot that the aws plugin is in-repo! Update that too.
* Remove code cleanup changes from this PR
* Wording and wrapping adjustment as requested.
* CreateOperation should only be implemented alongside ExistenceCheck
Closes#12329
Vault treats all POST or PUT HTTP requests equally - they default to
being treated as UpdateOperations, but, if a backend implements an
ExistenceCheck function, CreateOperations can be separated out when the
existence check returns false.
It follows, then, that if a CreateOperation handler is implemented
without an ExistenceCheck function, this is unreachable code - a coding
error. It's a fairly minor error in the grand scheme of things, but it
causes the generated OpenAPI spec to include x-vault-createSupported for
operations on which create can never actually be invoked - and promotes
muddled understanding of the create/update feature.
In this PR:
1) Implement a new test, which checks all builtin auth methods and
secrets engines can be successfully initialized. (This is important
to validate the next part.)
2) Expand upon the existing coding error checks built in to
framework.Backend, adding a check for this misuse of CreateOperation.
3) Fix up instances of improper CreateOperation within the Vault
repository - just two, transit and mock.
Note: At this point, the newly added test will **fail**.
There are improper uses of CreateOperation in all of the following:
vault-plugin-auth-cf
vault-plugin-auth-kerberos
vault-plugin-auth-kubernetes
vault-plugin-secrets-ad
vault-plugin-secrets-gcpkms
vault-plugin-secrets-kubernetes
vault-plugin-secrets-kv
vault-plugin-secrets-openldap
vault-plugin-secrets-terraform
each of which needs to be fixed and updated in go.mod here, before this
new check can be added.

* Add an opportunistic test of sys/internal/specs/openapi too
* OpenAPI: Separate ListOperation from ReadOperation
Historically, since Vault's ReadOperation and ListOperation both map to
the HTTP GET method, their representation in the generated OpenAPI has
been a bit confusing.
This was partially mitigated some time ago, by making the `list` query
parameter express whether it was required or optional - but only in
a way useful to human readers - the human had to know, for example, that
the schema of the response body would change depending on whether `list`
was selected.
Now that there is an effort underway to automatically generate API
clients from the OpenAPI spec, we have a need to fix this more
comprehensively. Fortunately, we do have a means to do so - since Vault
has opinionated treatment of trailing slashes, linked to operations
being list or not, we can use an added trailing slash on the URL path to
separate list operations in the OpenAPI spec.
This PR implements that, and then fixes an operation ID which becomes
duplicated, with this change applied.
See also hashicorp/vault-client-go#174, a bug which will be fixed by
this work.
* Set further DisplayAttrs in auth/github plugin
To mask out more duplicate read/list functionality, now being separately
generated to OpenAPI client libraries as a result of this change.
* Apply requested changes to operation IDs
I'm not totally convinced its worth the extra lines of code, but
equally, I don't have strong feelings about it, so I'll just make the
change.

Even in the edge case of improper use of regex patterns and operations.

* Add a couple more testcases, and some comments.
* Tweak spelling in comment
Vault API endpoints are defined using regexes in instances of the SDK's
framework.Path structure. However, OpenAPI does not use regexes, so a
translation is performed. It is technically possible that this
translation produces colliding OpenAPI paths from multiple
framework.Path structures. When this happens, there has formerly been no
diagnostic, and one result silently overwrites the other in a map.
As a result of this, several operations are currently accidentally
missing from the Vault OpenAPI, which is also the trigger for
https://github.com/hashicorp/vault-client-go/issues/180.
This PR adds a log message, to help catch such accidents so that they
can be fixed. Much of the PR is propagating a logger to the point where
it is needed, and adjusting tests for the API change.
With current Vault, this will result in the following being logged each
time a request is made which triggers OpenAPI generation:
```
[WARN] secrets.identity.identity_0cd35e4d: OpenAPI spec generation: multiple framework.Path instances generated the same path; last processed wins: path=/mfa/method
[WARN] secrets.identity.identity_0cd35e4d: OpenAPI spec generation: multiple framework.Path instances generated the same path; last processed wins: path=/mfa/method/totp
[WARN] secrets.identity.identity_0cd35e4d: OpenAPI spec generation: multiple framework.Path instances generated the same path; last processed wins: path=/mfa/method/okta

[WARN] secrets.identity.identity_0cd35e4d: OpenAPI spec generation: multiple framework.Path instances generated the same path; last processed wins: path=/mfa/method/pingid
```
I will submit a further PR to fix the issue - this one is just to add
the diagnostic.
* Fix non-deterministic ordering of 'required' field in OpenAPI spec
Fixes a minor annoyance I discovered whilst comparing before and after

* 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
Also remove comment "// TODO update after kv repo update" which was
added 4 years ago in #5687 - the implied update has not happened.
* Add changelog
* Update 18663.txt
Vault has gradually had the ability to pass query-string parameters
added to GET, then DELETE, and now recently LIST requests. Update
a comment which seems to date back to when no query-string parameters
were used at all.
This pull request adds 3 functions (and corresponding tests):
`testhelpers/response_validation.go`:
- `ValidateResponse`
- `ValidateResponseData`
field_data.go:
- `ValidateStrict` (has the "strict" validation logic)
The functions are primarily meant to be used in tests to ensure that the responses are consistent with the defined response schema. An example of how the functions can be used in tests can be found in #18636.
### Background
This PR is part of the ongoing work to add structured responses in Vault OpenAPI (VLT-234)
* Revert "Add mount path into the default generated openapi.json spec (UI) (#17926)"
This reverts commit db8efac708.
* Revert "Remove `generic_mount_paths` field (#18558)"
This reverts commit 79c8f626c5.
Move version out of SDK. For now it's a copy rather than move: the part not addressed by this change is sdk/helper/useragent.String, which we'll want to remove in favour of PluginString. That will have to wait until we've removed uses of useragent.String from all 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 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.
strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more
readable and removes the hardcoded -1.

* Add importKey, importCert to PKI storage
importKey is generally preferable to the low-level writeKey for adding
new entries. This takes only the contents of the private key (as a
string -- so a PEM bundle or a managed key handle) and checks if it
already exists in the storage.
If it does, it returns the existing key instance.
Otherwise, we create a new one. In the process, we detect any issuers
using this key and link them back to the new key entry.
The same holds for importCert over importKey, with the note that keys
are not modified when importing certificates.

* Add tests for importing issuers, keys
This adds tests for importing keys and issuers into the new storage

- GET /issuer/:ref - returns a JSON blob with information about this
issuer.
- POST /issuer/:ref - allows configuring information about issuers,
presently just its name.

* Add import to PKI Issuers API
This adds the two core import code paths to the API:
/issuers/import/cert and /issuers/import/bundle. The former differs from
the latter in that the latter allows the import of keys. This allows
operators to restrict importing of keys to privileged roles, while
allowing more operators permission to import additional certificates
(not used for signing, but instead for path/chain building).

* PKI migration writes out empty migration log entry
- Since the elements of the struct were not exported we serialized an empty
migration log to disk and would re-run the migration
* Add chain-building logic to PKI issuers path
With the one-entry-per-issuer approach, CA Chains become implicitly
constructed from the pool of issuers. This roughly matches the existing
expectations from /config/ca (wherein a chain could be provided) and
/intemediate/set-signed (where a chain may be provided). However, in
both of those cases, we simply accepted a chain. Here, we need to be
able to reconstruct the chain from parts on disk.
However, with potential rotation of roots, we need to be aware of
disparate chains. Simply concating together all issuers isn't
sufficient. Thus we need to be able to parse a certificate's Issuer and
Subject field and reconstruct valid (and potentially parallel)
parent<->child mappings.
This attempts to handle roots, intermediates, cross-signed
intermediates, cross-signed roots, and rotated keys (wherein one might
not have a valid signature due to changed key material with the same
subject).

* Add testing for chain building
Using the issuance infrastructure, we generate new certificates (either
roots or intermediates), positing that this is roughly equivalent to

By using ECDSA certificates, we avoid high signature verification and
key generation times.

* Add tests for manual chain building

* Fix full chain building
Don't set the legacy IssuingCA field on the certificate bundle, as we
prefer the CAChain field over it.
Additionally, building the full chain could result in duplicate
certificates when the CAChain included the leaf certificate itself. When
building the full chain, ensure we don't include the bundle's
certificate twice.

* Update CRL handling for multiple issuers
When building CRLs, we've gotta make sure certs issued by that issuer
land up on that issuer's CRL and not some other CRL. If no CRL is
found (matching a cert), we'll place it on the default CRL.
However, in the event of equivalent issuers (those with the same subject
AND the same key material) -- perhaps due to reissuance -- we'll only
create a single (unified) CRL for them.

* Update to CRLv2 Format to copy RawIssuer
When using the older Certificate.CreateCRL(...) call, Go's x509 library
copies the parsed pkix.Name version of the CRL Issuer's Subject field.
For certain constructed CAs, this fails since pkix.Name is not suitable
for round-tripping. This also builds a CRLv1 (per RFC 5280) CRL.
In updating to the newer x509.CreateRevocationList(...) call, we can
construct the CRL in the CRLv2 format and correctly copy the issuer's
name. However, this requires holding an additional field per-CRL, the
CRLNumber field, which is required in Go's implementation of CRLv2
(though OPTIONAL in the spec). We store this on the new
LocalCRLConfigEntry object, per-CRL.

it is signed with the correct keys.

* Add new PKI key prefix to seal wrapped storage (#15126)
* Refactor common backend initialization within backend_test
- Leverage an existing helper method within the PKI backend tests to setup a PKI backend with storage.
* Add ability to read legacy cert bundle if the migration has not occurred on secondaries.
- Track the migration state forbidding an issuer/key writing api call if we have not migrated
- For operations that just need to read the CA bundle, use the same tracking variable to
switch between reading the legacy bundle or use the new key/issuer storage.
- Add an invalidation function that will listen for updates to our log path to refresh the state
on secondary clusters.
* Always write migration entry to trigger secondary clusters to wake up
- Some PR feedback and handle a case in which the primary cluster does
not have a CA bundle within storage but somehow a secondary does.
* Update CA Chain to report entire chain
This merges the ca_chain JSON field (of the /certs/ca_chain path) with
the regular certificate field, returning the root of trust always. This
also affects the non-JSON (raw) endpoints as well.
We return the default issuer's chain here, rather than all known issuers
(as that may not form a strict chain).

* Allow explicit issuer override on roles
When a role is used to generate a certificate (such as with the sign/
and issue/ legacy paths or the legacy sign-verbatim/ paths), we prefer
that issuer to the one on the request. This allows operators to set an
issuer (other than default) for requests to be issued against,
effectively making the change no different from the users' perspective
as it is "just" a different role name.

* Expand NotAfter limit enforcement behavior
Vault previously strictly enforced NotAfter/ttl values on certificate
requests, erring if the requested TTL extended past the NotAfter date of
the issuer. In the event of issuing an intermediate, this behavior was
ignored, instead permitting the issuance.
Users generally do not think to check their issuer's NotAfter date when
requesting a certificate; thus this behavior was generally surprising.
Per RFC 5280 however, issuers need to maintain status information
throughout the life cycle of the issued cert. If this leaf cert were to
be issued for a longer duration than the parent issuer, the CA must
still maintain revocation information past its expiration.
Thus, we add an option to the issuer to change the desired behavior:
- err, to err out,
- permit, to permit the longer NotAfter date, or
- truncate, to silently truncate the expiration to the issuer's
NotAfter date.
Since expiration of certificates in the system's trust store are not
generally validated (when validating an arbitrary leaf, e.g., during TLS
validation), permit should generally only be used in that case. However,
browsers usually validate intermediate's validity periods, and thus
truncate should likely be used (as with permit, the leaf's chain will
not validate towards the end of the issuance period).

* Update PKI to new Operations framework (#15180)
The backend Framework has updated Callbacks (used extensively in PKI) to
become deprecated; Operations takes their place and clarifies forwarding
of requests.
We switch to the new format everywhere, updating some bad assumptions
about forwarding along the way. Anywhere writes are handled (that should
be propagated to all nodes in all clusters), we choose to forward the
request all the way up to the performance primary cluster's primary
node. This holds for issuers/keys, roles, and configs (such as CRL
config, which is globally set for all clusters despite all clusters
having their own separate CRL).

simply rebuild the CRL at that time (from the remaining revoked storage
entries).

* Add issuer usage restrictions bitset
This allows issuers to have usage restrictions, limiting whether they

(but potentially letting the CRL generation continue).
Setting both fields to false effectively forms a soft delete capability.
