* Allow Proof of Possession based revocation
Revocation by proof of possession ensures that we have a private key
matching the (provided or stored) certificate. This allows callers to
revoke certificate they own (as proven by holding the corresponding
private key), without having an admin create innumerable ACLs around
the serial_number parameter for every issuance/user.
We base this on Go TLS stack's verification of certificate<->key
matching, but extend it where applicable to ensure curves match, the
private key is indeed valid, and has the same structure as the
corresponding public key from the certificate.
This endpoint currently is authenticated, allowing operators to disable
the endpoint if it isn't desirable to use, via ACL policies.

* Leave revoke-with-key authenticated
After some discussion, given the potential for DoS (via submitting a lot
of keys/certs to validate, including invalid pairs), it seems best to
leave this as an authenticated endpoint. Presently in Vault, there's no
way to have an authenticated-but-unauthorized path (i.e., one which
bypasses ACL controls), so it is recommended (but not enforced) to make
this endpoint generally available by permissive ACL policies.

* 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.

* Add PSS signature support to Vault PKI engine
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* 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

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.

* 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.

structs and mapstructure aren't really used within Vault much any more,
so we should start removing them. Luckily there was only one externally
accessible place where structs was used (AIA URLs config) so that was
easy to remove. The rest is mostly structure tag changes.
path_roles_tests.go relied on mapstructure in some places that broke,
but otherwise backend_test.go hasn't yet been modified to remove the
dependency on mapstructure. These didn't break as the underlying
CertBundle didn't get mapstructure support removed (as its in the SDK).

Add database plugin metrics around connections
This is a replacement for #15923 that takes into account recent lock
cleanup.
I went ahead and added back in the hanging plugin test, which I meant to
add in #15944 but forgot.
I tested this by spinning up a statsd sink in the tests and verifying I
got a stream of metrics:
```
$ nc -u -l 8125 | grep backend
test.swenson-Q9Q0L72D39.secrets.database.backend.connections.count.pgx.5.:1.000000|g
test.swenson-Q9Q0L72D39.secrets.database.backend.connections.count.pgx.5.:0.000000|g
test.swenson-Q9Q0L72D39.secrets.database.backend.connections.count.pgx.5.:1.000000|g
test.swenson-Q9Q0L72D39.secrets.database.backend.connections.count.pgx.5.:0.000000|g
```
We have to rework the shared gauge code to work without a full
`ClusterMetricSink`, since we don't have access to the core metrics from
within a plugin.
This only reports metrics every 10 minutes by default, but it solves
some problems we would have had with the gauge values becoming stale and
needing to be re-sent.

When users pass the path of the bundle to the API, rather than the
contents of the bundle (say, by omitting the `@` symbol on a Vault CLI
request), give a better error message indicating to the user what the
potential problem might be. While a larger bound for certificates was
given (75 bytes, likely 100 would be fine as well), a smaller bound had
to be chosen for keys as there's less standard DER encoding data around

* Allow revocation of certs with key-less issuers
In Vault 1.11's multiple issuer functionality, we incorrectly fetched
the full CA signing bundle for validating revocation of leaf certs (when
attempting to prohibit revocation of issuers in the mount). When the
issuer lacked a key (such as the root issuer on an intermediate mount),
this signing bundle creation failed.
Instead of fetching the full CA signing bundle, fetch instead the raw
certutil.CertBundle and parse it (to x509.Certificate form) ourselves.
This manifests as the error on revocation:

This new parameter allows disabling all validations on a common name,

Presently, the default behavior is to allow either an email address

Operators can restrict roles to just a single option (e.g., for email
certs, limit CNs to have strictly email addresses and not hostnames).
By setting the value to `disabled`, CNs of other formats can be accepted
without validating their contents against our minimal correctness checks
for email/hostname/wildcard that we typically apply even when broad
permissions (allow_any_name=true, enforce_hostnames=false, and
allow_wildcard_certificates=true) are granted on the role.

* Fix handling of username_as_alias during LDAP authentication
There is a bug that was introduced in the LDAP authentication method by https://github.com/hashicorp/vault/pull/11000.
It was thought to be backward compatible but has broken a number of users. Later
a new parameter `username_as_alias` was introduced in https://github.com/hashicorp/vault/pull/14324
to make it possible for operators to restore the previous behavior.
The way it is currently working is not completely backward compatible thought
because when username_as_alias is set, a call to GetUserAliasAttributeValue() will
first be made, then this value is completely discarded in pathLogin() and replaced
by the username as expected.
This is an issue because it makes useless calls to the LDAP server and will break
backward compatibility if one of the constraints in GetUserAliasAttributeValue()
is not respected, even though the resulting value will be discarded anyway.
In order to maintain backward compatibility here we have to only call
GetUserAliasAttributeValue() if necessary.
Since this change of behavior was introduced in 1.9, this fix will need to be
backported to the 1.9, 1.10 and 1.11 branches.

* reduce number of roles to iterate through; only verify roles after migration. ignore roles deleted behind our back.
* Protect against key and issuer name re-use

- Validate an assumption within the key import api, that we were provided a single key
- Add additional tests on the new key generation and key import handlers.
* Protect key import api end-users from using "default" as a name
- Do not allow end-users to provide the value of default as a name for key imports

* Add missing api-docs for PKI key import
* Warn on empty Subject field for issuers
When generating a root or signing an intermediate certificate, it is
possible to have Vault generate a certificate with an empty Subject.
These don't validate in most TLS implementations well, so add a warning.
Note that non-Common Name fields could be present to make a non-empty
subject, so simply requiring a CommonName isn't strictly the best.
For example:
$ vault write pki/root/generate/exported common_name=""
WARNING! The following warnings were returned from Vault:
* This issuer certificate was generated without a Subject; this makes
it likely that issuing leaf certs with this certificate will cause TLS
validation libraries to reject this certificate.

* Remove signature_bits on intermediate generate
This extraneous field wasn't respected during intermediate generation
and it isn't clear that it should be. Strictly, this field, if it were
to exist, would control the CSR's internal signature algorithm (certutil
defaults to the sane SHA-256 here). However, there's little value in
changing this as the signing authority can and probably will override
the final certificate's signature bits value, completely ignoring
whatever was in the provided CSR.
Removing this field will now cause warnings for those providing the
parameter (which already wasn't respected), which is the desired
behavior. No breakage should occur as a result of this change.

- The key_type field should be used solely for the key algorithm but as implemented

hit if many managed keys existed so we will simply remove the field from the list

* Fix related issuer detection in CRL building

- Leverage the legacyBundleShimID though out the path of CRL building

same issuerId everywhere
- Address some locking issues that might lead to a bad read/write when
switching from legacy to non-legacy mode on startup and post-migration
* Add test suite for PKI apis pre-migration to new issuer storage format
- Add tests that validate all apis work as expected in pre-migration mode
- Add tests for apis that we don't expect to work, they should return a

* Return the ca_chain response from root issued cert api
* Fix parent selection in cert chain building
When building chains, we'd choose the next neighbor from Go's

intermediates, as this allows us to have a more consistent chain,
putting roots before their cross-signed equivalents rather than
potentially at the end.
We additionally now ensure chains are stable.

- Add a test that validates the behaviour
- Update the field description blurbs.
* Move existing test helpers into a new test_helpers.go file within PKI
* Compare issuer certificates by cert, signature algo and signature
- Instead of comparing the strings of a certificate, instead leverage
the Go Raw attribute within a parsed certificate to compare. The Raw
attribute is a byte array of an ASN.1 DER containing the cert,
signature algo and signature.
- Rework a bit of the importIssuers function as well to fail checks on the
inbound issuer earlier as well as load keys/issuers just before we need
them
* Prevent revocation of issuers using revokeCert
Similar to the existing behavior, we'll prevent the revocation of
existing issuer certificates from the existing /revoke/:serial endpoint
for now. This is because a serial number alone is not enough information
(in the worst case) to precisely identify an issuer (as intermediates
signed by two separate external (e.g., OpenSSL) CAs using incremental
serial numbers might have the same serial number).
Additionally, we fix revoking certs on performance secondary clusters,
when they've not yet been migrated.
In a separate change, we'll open up a separate code path to revoke
issuers, ensuring we know exactly which issuer is revoked (and which CRL
it should belong on at time of revocation).

* 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.

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

This adds the two core import code paths to the API:
/issuers/import/cert and /issuers/import/bundle. The former differs from

* Add support for deleting all keys, issuers
The old DELETE /root code must now delete all keys and issuers for

for finer control.
In the process, we detect whether the deleted key/issuers was set as the
default. This will allow us to warn (from the single key/deletion issuer
code) whether or not the default was deleted (while allowing the
operation to succeed).

* 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

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

Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Fix handling of duplicate names
With the new issuer field (manual_chain), we can no longer err when a
name already exists: we might be updating the existing issuer (with the
same name), but changing its manual_chain field. Detect this error and
correctly handle it.

* Add tests for manual chain building
We break the clique, instead building these chains manually, ensuring
that the remaining chains do not change and only the modified certs
change. We then reset them (back to implicit chain building) and ensure
we get the same results as earlier.

* Add stricter verification of issuers PEM format
This ensures each issuer is only a single certificate entry (as
validated by count and parsing) without any trailing data.
We further ensure that each certificate PEM has leading and trailing
spaces removed with only a single trailing new line remaining.

* 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.

* Allow fetching the specified issuer's CRL
We add a new API endpoint to fetch the specified issuer's CRL directly

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

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.

VAULT-5827 Don't prepare SQL queries before executing them
We don't support proper prepared statements, i.e., preparing once and
executing many times since we do our own templating. So preparing our
queries does not really accomplish anything, and can have severe
performance impacts (see
https://github.com/hashicorp/vault-plugin-database-snowflake/issues/13
for example).
This behavior seems to have been copy-pasted for many years but not for
any particular reason that we have been able to find. First use was in
https://github.com/hashicorp/vault/pull/15
So here we switch to new methods suffixed with `Direct` to indicate
that they don't `Prepare` before running `Exec`, and switch everything
here to use those. We maintain the older methods with the existing
behavior (with `Prepare`) for backwards compatibility.
