Add per-issuer AIA URI information to PKI secrets engine (#16563)
* Add per-issuer AIA URI information

Per discussion on GitHub with @maxb, this allows issuers to have their
own copy of AIA URIs. Because each issuer has its own URLs (for CA and
CRL access), its necessary to mint their issued certs pointing to the
correct issuer and not to the global default issuer. For anyone using
multiple issuers within a mount, this change allows the issuer to point
back to itself via leaf's AIA info.

Allow marking issuers as revoked (#16621)
* Allow marking issuers as revoked

This allows PKI's issuers to be considered revoked and appear on each
others' CRLs. We disable issuance (via removing the usage) and prohibit
modifying the usage via the regular issuer management interface.

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.

Add proof possession revocation for PKI secrets engine (#16566)
* 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-based revocation to PKI secrets engine (#16564)
* Refactor serial creation to common helper

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

* 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 support to PKI Secrets Engine (#16519)
* 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
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

Allow old certs to be cross-signed (#16494)
* 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.

Make PKI tests run in parallel (#16514)
This decreases the total time to run the test suite significantly. From
the last PR, we were at 151s:

> [cipherboy@xps15 pki]$ go test -count=1 github.com/hashicorp/vault/builtin/logical/pki
> ok  	github.com/hashicorp/vault/builtin/logical/pki	151.182s

Now we're around 60s:

> [cipherboy@xps15 pki]$ go test -count=1 github.com/hashicorp/vault/builtin/logical/pki
> ok  	github.com/hashicorp/vault/builtin/logical/pki	61.838s

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.

Remove structs, mapstructure from PKI storage (#16190)
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.

Fix leaf revocation under intermediate CAs (#16052)
* Add test for revocation under intermediate CA

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

* 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:

> URL: PUT http://127.0.0.1:8200/v1/pki_int/revoke
> * could not fetch the CA certificate for issuer id 156e1b99-4f04-5b5e-0036-cc0422c0c0d3: unable to fetch corresponding key for issuer 156e1b99-4f04-5b5e-0036-cc0422c0c0d3; unable to use this issuer for signing

Cleanup and simplify lock usage in database plugin

Following up from discussions in #15923 and #15933, I wanted to split
out a separate PR that drastically reduced the complexity of the use of
the databaseBackend lock. We no longer need it at all for the
`credRotationQueue`, and we can move it to be solely used in a few,
small connections map management functions.

Add explicit cn_validations field to PKI Roles (#15996)
* Add cn_validations PKI Role parameter

This new parameter allows disabling all validations on a common name,
enabled by default on sign-verbatim and issuer generation options.

Presently, the default behavior is to allow either an email address
(denoted with an @ in the name) or a hostname to pass validation.
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.

Allow reading Nomad CA/Client cert configuration (#15809)

In the Nomad secret engine, writing to /nomad/config/access allows users
to specify a CA certificate and client credential pair. However, these
values are not in the read of the endpoint, making it hard for operators
to see if these values were specified and if they need to be rotated.

Add `ca_cert` and `client_cert` parameters to the response, eliding the
`client_key` parameter as it is more sensitive (and should most likely
be replaced at the same time as `client_cert`).

Update AWS auth method certificates

Add tests that the `rsa2048` document can also be verified using the
`pkcs7` field for AWS auth.

Due to the use of SHA-1-based signatures for the `identity` and `pkcs7`
methods, we want to encourage moving toward using the RSA 2048 workflow,
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/verify-rsa2048.html

This doesn't require code changes for Vault necessarily, but adding in
the (many) certificates will help end users.

Also adds `rsa2048` option to API to fetch the RSA 2048 signature.

I will make a PR to update to the AWS auth docs to document the RSA 2048
flow soon after this.

Fix handling of username_as_alias during LDAP authentication (#15525)
* 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.

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 (#15478)
* 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.

Prevent revoking all issuer certificates (#15289)
* 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.

 - POST /issuer/:ref - allows configuring information about issuers,

* Move setting PKI defaults from writeCaBundle to proper import{keys,issuer} methods

While testing, a panic was discovered:

 - Use the addIssuerRefField function instead of redefining the field in various locations.

* Rework PKI test TestBackend_Root_Idempotency

 - Validate that generate/root calls are no longer idempotent, but the bundle importing
   does not generate new keys/issuers
 - As before make sure that the delete root api resets everything
 - Address a bug within the storage that we bombed when we had multiple different
   key types within storage.

* Assign Name=current to migrated key and issuer

 - Detail I missed from the RFC was to assign the Name field as "current" for migrated key and issuer.

* Build CRL upon PKI intermediary set-signed api called

 - Add a call to buildCRL if we created an issuer within pathImportIssuers
 - Augment existing FullCAChain to verify we have a proper CRL post set-signed api call
 - Remove a code block writing out "ca" storage entry that is no longer used.

* Identify which certificate or key failed

When importing complex chains, we should identify in which certificate
or key the failure occurred.

* 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
importing an external bundle (minus error handling during partial
imports). This allows us to incrementally construct complex chains,
creating reissuance cliques and cross-signing cycles.

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

* Fix handling of duplicate names

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

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.

* 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).

The backend Framework has updated Callbacks (used extensively in PKI) to

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).
