Add a corresponding global setting for the existing route-level
jwt_issuer_format option. The route-level option will take precedence
when set to a non-empty string.
Add a new option for filtering to a subset of directory groups in the
Pomerium JWT and Impersonate-Group headers. Add a JWTGroupsFilter field
to both the Options struct (for a global filter) and to the Policy
struct (for per-route filter). These will be populated only from the
config protos, and not from a config file.
If either filter is set, then for each of a user's groups, the group
name or group ID will be added to the JWT groups claim only if it is an
exact string match with one of the elements of either filter.
* Optimize policy iterators (go1.23)
This modifies (*Options).GetAllPolicies() to use a go 1.23 iterator
instead of copying all policies on every call, which can be extremely
expensive. All existing usages of this function were updated as
necessary.
Additionally, a new (*Options).NumPolicies() method was added which
quickly computes the number of policies that would be given by
GetAllPolicies(), since there were several usages where only the
number of policies was needed.
* Fix race condition when assigning default envoy opts to a policy
Add a parameter to evaluator.New() for the previous Evaluator (if any).
If the evaluatorConfig is the same, reuse any PolicyEvaluators for
policies that have not changed from the previous Evaluator.
Use the route IDs along with the policy checksums to determine whether a
given policy has changed. Similarly, add a new cacheKey() method to the
evaluatorConfig to compute a checksum used for determine whether the
evaluatorConfig has changed. (Store this checksum on the Evaluator.)
Add a new match_subject_alt_names option to the downstream_mtls settings
group. This setting can be used to further constrain the allowed client
certificates by requiring that certificates contain a Subject
Alternative Name of a particular type, matching a particular regex.
When set, populate the corresponding match_typed_subject_alt_names
setting within Envoy, and also implement a corresponding check in the
authorize service.
Add a new max_verify_depth option to the downstream_mtls settings group,
with a default value of 1 (to match the behavior of current Pomerium
releases).
Populate the corresponding setting within Envoy, and also implement a
depth check within isValidClientCertificate() in the authorize service.
Add an "enforcement" option to the new downstream mTLS configuration
settings group.
When not set, or when set to "policy_default_deny", keep the current
behavior of adding an invalid_client_certificate rule to all policies.
When the enforcement mode is set to just "policy", remove the default
invalid_client_certificate rule that would be normally added.
When the enforcement mode is set to "reject_connection", configure the
Envoy listener with the require_client_certificate setting and remove
the ACCEPT_UNTRUSTED option.
Add a corresponding field to the Settings proto.
Update isValidClientCertificate() to also consult the configured
certificate revocation lists. Update existing test cases and add a new
unit test to exercise the revocation support. Restore the skipped
integration test case.
Generate new test certificates and CRLs using a new `go run`-able source
file.
