* Skip CRL building steps when disabled
This skips a number of steps during CRL build when it is disabled (and
forceNew is not set). In particular, we avoid fetching issuers, we avoid
associating issuers with revocation entries (and building that in-memory
mapping), making CRL building more efficient.
This means that there'll again be very little overhead on clusters with
the CRL disabled.

* 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).

* 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.

* Allow old certs to be cross-signed
In Vault 1.11, we introduced cross-signing support, but the earlier SKID
field change in Vault 1.10 causes problems: notably, certs created on
older versions of Vault (<=1.9) or outside of Vault (with a different
SKID method) cannot be cross-signed and validated in OpenSSL.
In particular, OpenSSL appears to be unique in requiring a SKID/AKID
match for chain building. If AKID and SKID are present on an otherwise
valid client/parent cert pair and the values are different, OpenSSL will
not build a valid path over those two, whereas most other chain
validation implementations will.
Regardless, to have proper cross-signing support, we really aught to
support copying an SKID. This adds such support to the sign-intermediate
endpoint. Support for the /issue endpoint is not added, as cross-signing
leaf certs isn't generally useful and can accept random SKIDs.

Notably, Go will correctly handle parallelizing tests across both
packages and within a package, so this shouldn't really impact test
runners (if they're already saturated).
The only gotcha in this approach is that the call to t.Run(...) becomes
effectively async; this means we either need to not mark the test as
parallel or shadow any loop variables inside the scope of the loop to
allow the t.Run to have the correct copy.

* 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

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.

* 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).

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.

In previous versions of Vault, it was possible to sign an empty CRL
(when the CRL was disabled and a force-rebuild was requested). Add a

* Allow fetching the specified issuer's CRL
We add a new API endpoint to fetch the specified issuer's CRL directly
(rather than the default issuer's CRL at /crl and /certs/crl). We also
add a new test to validate the CRL in a multi-root scenario and ensure
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).

* Remove deleted issuers' CRL entries
Since CRLs are no longer resolvable after deletion (due to missing
issuer ID, which will cause resolution to fail regardless of if an ID or

In the event that this issuer comes back (with key material), we can
simply rebuild the CRL at that time (from the remaining revoked storage
entries).

unauthenticated, whereas the bare endpoint would remain authenticated
and usually privileged.

* Add issuer usage restrictions bitset
This allows issuers to have usage restrictions, limiting whether they
can be used to issue certificates or if they can generate CRLs. This

with the CRL enabled) or allows the issuer to not issue new certificates
(but potentially letting the CRL generation continue).
Setting both fields to false effectively forms a soft delete capability.
