… performance Address review findings from the credential storage drivers PR: - Route additional_credentials through the driver on refresh to prevent silent data loss for multi-credential providers (e.g. AWS STS) - Clean up stored credential handles on CAS failure during refresh to prevent orphaned secrets in external backends - Enforce namespace validation in the Kubernetes Secrets driver to prevent cross-namespace credential access when allow_reference_namespace is not enabled - Cache Vault Kubernetes auth tokens with 80% TTL to avoid re-authenticating on every credential operation - Parallelize resolve_credentials in all three drivers using try_join_all for faster sandbox startup - Add existingSecret support for the KEK Secret to fix helm template/GitOps workflows where lookup returns empty and regenerates the key - Document RBAC blast radius for the Kubernetes Secrets credential driver and recommend a dedicated namespace Signed-off-by: Varsha Prasad <varshaprasad96@gmail.com> Signed-off-by: Varsha Prasad Narsing <varshaprasad96@gmail.com>
…rallelize operations Use resourceVersion optimistic concurrency with retry loop for K8s Secret ownership checks to prevent TOCTOU races. Switch Vault token cache from RwLock to Mutex with double-check pattern to prevent thundering herd on cache miss. Parallelize credential store and delete operations across independent keys using try_join_all.

…ate cleanup Replace try_join_all with join_all in credential store/delete operations to handle partial failures — successfully-stored handles are cleaned up when another key fails. Add retry loop with conflict detection to db-credstore delete_credential, matching the K8s driver pattern. Consolidate 4 manual cleanup_pre_stored_provider_credentials call sites into a single error handler using an async block. Remove inconsistent .trim() from db-credstore validate_handle_owner.

Remove attempt-count guard from 409/Aborted match arms in retry loops so the post-loop Status::aborted error is reachable after exhausting retries. Previously, last-attempt conflicts fell through to the catch-all error arm, producing misleading Status::unavailable errors. Remove duplicate validation calls that ran after prepare_provider_credential_update but outside the cleanup-protected async block, which would leak pre-stored handles on failure.

Superseding #1986 while @TaylorMutch is away
Summary
Adds gateway-owned credential storage for Providers v2. New provider credential
writes now persist opaque handles instead of inline secret values, with default
encrypted database storage when no external credential backend is configured and
opt-in Kubernetes Secrets or Vault backends for deployments that want dedicated
secret storage.

Default Behavior
Credential drivers are opt-in for external backends. If
[openshell.gateway].credential_driversis omitted, the gateway uses the defaultencrypted database credential store. The submitted secret is encrypted into a
driver-owned credential object outside the provider record, and the provider
record stores only an opaque handle.
The explicit empty list form,
credential_drivers = [], is invalid. Operatorsshould omit the field for default encrypted DB storage or select exactly one
external backend such as
kubernetes-secretsorvault.Existing provider records that already contain inline plaintext credentials are
still resolved for upgrade compatibility, but new provider creates and credential
updates use credential storage handles.
