* Don't race for CRL rebuilding capability check
Core has recently seen some data races during SystemView/replication
updates between them and the PKI subsystem. This is because this
SystemView access occurs outside of a request (during invalidation
handling) and thus the proper lock isn't held.
Because replication status cannot change within the lifetime of a plugin
(and instead, if a node switches replication status, the entire plugin
instance will be torn down and recreated), it is safe to cache this
once, at plugin startup, and use it throughout its lifetime.
Thus, we replace this SystemView access with a stored boolean variable
computed ahead of time.

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.
This option was elided from the default value for the usage field. This
results in issuers "losing" ocsp-signing when they're POST updated. Most
issuers will want OCSP signing by default, so it makes sense to add this
as the default.

* Add path to manually rebuild delta CRLs
The crl/rotate-delta path behaves like crl/rotate, triggering a
cluster-local rebuild of just the delta CRL. This is useful for when
delta CRLs are enabled with a longer-than-desired auto-rebuild period
after some high-profile revocations occur.
In the event delta CRLs are not enabled, this becomes a no-op.

By setting pause_duration, operators can have a little control over the

This allows other operations to occur during this gap and potentially
allows the tidy operation to consume less resources per unit of time
(due to the sleep -- though obviously consumes the same resources over
the time of the operation).

* Add ability to perform automatic tidy operations
This enables the PKI secrets engine to allow tidy to be started
periodically by the engine itself, avoiding the need for interaction.
This operation is disabled by default (to avoid load on clusters which
don't need tidy to be run) but can be enabled.
In particular, a default tidy configuration is written (via
/config/auto-tidy) which mirrors the options passed to /tidy. Two
additional parameters, enabled and interval, are accepted, allowing
auto-tidy to be enabled or disabled and controlling the interval
(between successful tidy runs) to attempt auto-tidy.
Notably, a manual execution of tidy will delay additional auto-tidy
operations. Status is reported via the existing /tidy-status endpoint.

* Allow generation of up-to-date delta CRLs
While switching to periodic rebuilds of CRLs alleviates the constant
rebuild pressure on Vault during times of high revocation, the CRL
proper becomes stale. One response to this is to switch to OCSP, but not
every system has support for this. Additionally, OCSP usually requires
connectivity and isn't used to augment a pre-distributed CRL (and is
instead used independently).
By generating delta CRLs containing only new revocations, an existing
CRL can be supplemented with newer revocations without requiring Vault
to rebuild all complete CRLs. Admins can periodically fetch the delta
CRL and add it to the existing CRL and applications should be able to
support using serials from both.
Because delta CRLs are emptied when the next complete CRL is rebuilt, it
is important that applications fetch the delta CRL and correlate it to
their complete CRL; if their complete CRL is older than the delta CRL's
extension number, applications MUST fetch the newer complete CRL to
ensure they have a correct combination.
This modifies the revocation process and adds several new configuration
options, controlling whether Delta CRLs are enabled and when we'll
rebuild it.

* Refactor revInfo checking to helper
This allows us to validate whether or not a revInfo entry contains a

* Refactor issuer fetching for revocation purposes

* Allow tidy to associate revoked certs, issuers
When revoking a certificate, we need to associate the issuer that signed

performed during CRL building (and still remains so), but when running
without CRL building and with only OCSP, performance will degrade as the
issuer needs to be found each time.
Instead, allow the tidy operation to take over this role, allowing us to
increase the performance of OCSP and CRL in this scenario, by decoupling
issuer identification from CRL building in the ideal case.

* Prevent revoking roots from appearing on own CRLs
This change ensures that when marking a root as revoked, it no longer
appears on its own CRL. Very few clients support this event (as
generally only leaves/intermediates are checked for presence on a
parent's CRL) and it is technically undefined behavior (if the root is
revoked, its own CRL should be untrusted and thus including it on its
own CRL isn't a safe/correct distribution channel).
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Ensure stability of revInfo issuer identification
As mentioned by Kit, iterating through each revInfoEntry and associating
the first issuer which matches it can cause churn when many (equivalent)
issuers are in the system and issuers come and go (via CRLSigning usage,
which has been modified in this release as well). Because we'd not
include issuers without CRLSigning usage, we'd cause our verification
helper, isRevInfoIssuerValid, to think the issuer ID is no longer value
(when instead, it just lacks crlSigning bits).
We address this by pulling in all issuers we know of for the
identification. This allows us to keep valid-but-not-for-signing
issuers, and use other representatives of their identity set for
signing/building the CRL (if they are enabled for such usage).
As a side effect, we now no longer place these entries on the default
CRL in the event all issuers in the CRL set are without the usage.

* Identify issuer on revocation
When we attempt to revoke a leaf certificate, we already parse all of

accidentally revoke an issuer via the leaf revocation endpoint. We can

comparison and signature checking) to the revoked cert in its revocation
info. This will help OCSP, avoiding the case where the OCSP handler
needs to associate a certificate to its issuer.

(at issuer configuration time) that we can't possibly support this
operation and hopefully prevent users from running into the more cryptic
Go error.
Note that this does not apply for OCSP EKU: the EKU exists, per RFC 6960
Section 2.6 OCSP Signature Authority Delegation, to allow delegation of
OCSP signing to a child certificate. This EKU is not necessary on the
issuer itself, and generally assumes issuers are allowed to issue OCSP
responses regardless of KU/EKU.

* Allow automatic rebuilding of CRLs
When enabled, periodic rebuilding of CRLs will improve PKI mounts in two
way:
1. Reduced load during periods of high (new) revocations, as the CRL
isn't rebuilt after each revocation but instead on a fixed schedule.
2. Ensuring the CRL is never stale as long as the cluster remains up,
by checking for next CRL expiry and regenerating CRLs before that
happens. This may increase cluster load when operators have large
CRLs that they'd prefer to let go stale, rather than regenerating
fresh copies.
In particular, we set a grace period before expiration of CRLs where,
when the periodic function triggers (about once a minute), we check
upcoming CRL expirations and check if we need to rebuild the CRLs.

A separate endpoint is necessary because issuers (especially if signed
by a third-party CA using incremental serial numbers) might share a
serial number (e.g., an intermediate under cross-signing might share the
same number as an external root or an unrelated intermediate).
When the next CRL rebuild happens, this issuer will then appear on
others issuers CRLs, if they validate this issuer's certificate.

private key is indeed valid, and has the same structure as the
corresponding public key from the certificate.

* Ignore EC PARAMETER blocks during issuer import
While older versions of Vault supported sending this, we broke such
support in 1.11. Ignore them from the manage issuers endpoint (which is
aliased to the old /config/ca path) -- but keep erring in the import
keys paths. The latter is a new endpoint not aliased to anything and
only expects a single PEM block.

* Add BYOC revocation to PKI mount
This allows operators to revoke certificates via a PEM blob passed to
Vault. In particular, Vault verifies the signature on the certificate
from an existing issuer within the mount, ensuring that one indeed
issued this certificate. The certificate is then added to storage and
its serial submitted for revocation.
This allows certificates generated with no_store=true to be submitted
for revocation afterwards, given a full copy of the certificate. As a
consequence, all roles can now safely move to no_store=true (if desired
for performance) and revocation can be done on a case-by-case basis.

strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more

* Add PSS signature support to Vault PKI engine

* Use issuer's RevocationSigAlg for CRL signing
We introduce a new parameter on issuers, revocation_signature_algorithm
to control the signature algorithm used during CRL signing. This is
because the SignatureAlgorithm value from the certificate itself is
incorrect for this purpose: a RSA root could sign an ECDSA intermediate
with say, SHA256WithRSA, but when the intermediate goes to sign a CRL,
it must use ECDSAWithSHA256 or equivalent instead of SHA256WithRSA. When
coupled with support for PSS-only keys, allowing the user to set the
signature algorithm value as desired seems like the best approach.

* Allow roots to self-identify revocation alg
When using PSS support with a managed key, sometimes the underlying
device will not support PKCS#1v1.5 signatures. This results in CRL
building failing, unless we update the entry's signature algorithm
prior to building the CRL for the new root.
With a RSA-type key and use_pss=true, we use the signature bits value to
decide which hash function to use for PSS support.

* Add clearer error message on failed import
When CRL building fails during cert/key import, due to PSS failures,
give a better indication to the user that import succeeded its just CRL
building that failed. This tells them the parameter to adjust on the
issuer and warns that CRL building will fail until this is fixed.
