- This fix was incorrect as now the tests and program are double
URL encoding the OCSP GET requests, so the base64 + characters
when using Vault proper are becoming space characters.
* Use the unified CRL on legacy CRL paths if UnifiedCRLOnExistingPaths is set
- If the crl configuration option unified_crl_on_existing_paths is set
to true along with the unified_crl feature, provide the unified crl
on the existing CRL paths.
- Added some test helpers to help debugging, they are being used by
the ENT test that validates this feature.
* Rename method to shouldLocalPathsUseUnified
* Use UTC for leaf exceeding CA's notAfter
When generating a leaf which exceeds the CA's validity period, Vault's
error message was confusing as the leaf would use the server's time
zone, but the CA's notAfter date would use UTC. This could cause
user confusion as the leaf's expiry might look before the latter, due
to using different time zones. E.g.:
> cannot satisfy request, as TTL would result in notAfter
> 2023-03-06T16:41:09.757694-08:00 that is beyond the expiration of
> the CA certificate at 2023-03-07T00:29:52Z
Consistently use UTC for this instead.

key generation but places limits on TTL and doesn't require Vault reach
out to provision each key on the specified host, making it much more
secure.

* Read total cert counts with atomic.LoadUint32(...)
When generating the tidy status, we read the values of two backend
atomics, b.certCount and b.revokedCertCount, without using the atomic
load operation. This resulted in a data race when the status was read
at the same time as an on-going tidy operation:

* Allow unification of revocations on other clusters
If a BYOC revocation occurred on cluster A, while the cert was initially
issued and stored on cluster B, we need to use the invalidation on the
unified entry to detect this: the revocation queues only work for
non-PoP, non-BYOC serial only revocations and thus this BYOC would be
immediately accepted on cluster A. By checking all other incoming
revocations for duplicates on a given cluster, we can ensure that
unified revocation is consistent across clusters.

* Add support to build unified CRLs
This allows us to build unified versions of both the complete and delta
CRLs. This mostly involved creating a new variant of the
unified-specific CRL builder, fetching certs from each cluster's storage
space.
Unlike OCSP, here we do not unify the node's local storage with the
cross-cluster storage: this node is the active of the performance
primary, so writes to unified storage happen exactly the same as
writes to cluster-local storage, meaning the two are always in
sync. Other performance secondaries do not rebuild the CRL, and hence
the out-of-sync avoidance that we'd like to solve with the OCSP
responder is not necessary to solve here.

Notably, this commit also changes us to not write Delta WALs when Delta
CRLs is disabled (versus previously doing it when auto rebuild is
enabled in case Delta CRLs were later asked for), and instead,
triggering rebuilding a complete CRL so we don't need up-to-date Delta
WAL info.

* 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.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* 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

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

* Rename revokeCert variable to identify serial number formatting
* Refactor out lease specific behavior out of revokeCert
- Isolate the specific behavior regarding revoking lease specific
certificates outside of the revokeCert function and into the only
caller that leveraged used it.
- This allows us to simplify revokeCert a little bit and keeps the
function purely about revoking a certificate
* Within revokeCert short circuit the already revoked use-case
- Make the function a little easier to process by exiting early
if the certificate has already been revoked.
* Do not load certificates from storage multiple times during revocation
- Isolate the loading of a certificate and parsing of a certificate
into a single attempt, either when provided the certificate for BYOC
revocation or strictly from storage for the other revocation types.
* With BYOC write certificate entry using dashes not the legacy colon char
* Allow tidy to backup legacy CA bundles
With the new tidy_move_legacy_ca_bundle option, we'll use tidy to move
the legacy CA bundle from /config/ca_bundle to /config/ca_bundle.bak.
This does two things:
1. Removes ca_bundle from the hot-path of initialization after initial
migration has completed. Because this entry is seal wrapped, this
may result in performance improvements.
2. Allows recovery of this value in the event of some other failure
with migration.
Notably, this cannot occur during migration in the unlikely (and largely
unsupported) case that the operator immediately downgrades to Vault
<1.11.x. Thus, we reuse issuer_safety_buffer; while potentially long,
tidy can always be run manually with a shorter buffer (and only this
flag) to manually move the bundle if necessary.
In the event of needing to recover or undo this operation, it is
sufficient to use sys/raw to read the backed up value and subsequently
write it to its old path (/config/ca_bundle).
The new entry remains seal wrapped, but otherwise isn't used within the
code and so has better performance characteristics.
Performing a fat deletion (DELETE /root) will again remove the backup
like the old legacy bundle, preserving its wipe characteristics.
