📝 WalkthroughWalkthroughThe OAGW gear is added as a tenant-scoped outbound gateway. It includes resource models, control-plane CRUD, in-memory storage, REST routes, proxy forwarding, plugins, rate limiting, CORS, SSRF checks, OAuth2 authentication, error envelopes, runtime wiring, and end-to-end tests. ChangesOAGW gateway
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The new gateway implementation can bypass SSRF protections, send requests without configured authentication, create conflicting routes, or delete still-referenced plugins; other policy and API inconsistencies can reject valid requests or produce incorrect routing behavior. The PR is not merge-ready until the major security and correctness issues are resolved. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@gears/system/oagw/oagw/src/api/rest/error.rs`:
- Around line 161-166: Add a resource-neutral GTS identifier for control-plane
not-found responses, then update domain_error_to_problem so missing upstream and
plugin errors use it while data-plane route failures continue using
ERR_ROUTE_NOT_FOUND. Preserve the existing 404 status and messages.
In `@gears/system/oagw/oagw/src/api/rest/handlers.rs`:
- Around line 105-107: Update route_priority and the corresponding FieldAccessor
handling in apply_filter_order so priority comparisons use numeric u64 ordering
rather than str::cmp, while preserving exact-match filtering semantics for
priority values such as 10.
In `@gears/system/oagw/oagw/src/domain/alias.rs`:
- Around line 66-68: Update validate_host to normalize the input with
normalize_host before applying length, IP, and label validation, so a single
trailing root dot such as api.openai.com. is accepted while other empty labels
remain invalid.
In `@gears/system/oagw/oagw/src/domain/control.rs`:
- Around line 612-613: Update endpoint validation in ControlPlaneService to
receive and retain OagwConfig.allow_http_upstream, then permit the http scheme
only when that setting is enabled; continue allowing https and wss
unconditionally and rejecting http when disabled.
In `@gears/system/oagw/oagw/src/domain/ratelimit.rs`:
- Around line 135-143: Update the rate-limit handling around
RateDecision::Limited so requests where policy.cost exceeds capacity do not
receive a finite retry_after_secs; reject that policy during validation or use
the existing permanent-limit value, while preserving finite wait calculations
for feasible costs.
In `@gears/system/oagw/oagw/src/infra/cors.rs`:
- Line 123: Update enrich_response so adding Origin to the Vary header preserves
any existing upstream Vary values, such as Accept-Encoding, instead of replacing
them via headers.insert; append or merge the value using the existing
header-handling API while retaining Origin in the resulting header.
- Around line 104-122: Update merge_cors to reject merged configurations that
contain a wildcard allowed origin with allow_credentials enabled, and ensure
enrich_response never emits that invalid combination. Update proxy_preflight to
pass the applicable CorsConfig into preflight_response so credentialed preflight
responses include Access-Control-Allow-Credentials.
In `@gears/system/oagw/oagw/src/infra/data_plane.rs`:
- Around line 1501-1511: Update client_ip to fall back to the request’s socket
peer address when trusted mode has no valid x-forwarded-for value, rather than
returning "unknown"; preserve the existing forwarded-header parsing and
non-trusted behavior. Also update rate_key so routes without an id use a
distinct peer/request-derived key instead of the shared "unknown" bucket.
In `@gears/system/oagw/oagw/src/infra/memory_repo.rs`:
- Around line 183-188: Update create_route and the repository operation around
check_route_match_unique so route conflict validation and insertion occur
atomically under the tenant-and-upstream key, preventing concurrent inserts of
overlapping route rules with different UUIDs. Preserve the existing conflict
contract and return DomainError::Conflict for duplicate UUIDs or conflicting
route definitions.
- Line 313: Update the reference comparisons in plugin_is_referenced to parse
both the stored GTS identifier and each binding’s plugin reference as UUIDs
before comparing them, so bare UUID and custom GTS forms match; preserve the
existing reference-detection behavior for invalid values.
In `@gears/system/oagw/oagw/src/infra/oauth2_auth.rs`:
- Around line 157-163: Apply OagwConfig.ssrf_policy through the configured
toolkit_http client for every OAuth outbound request, including OIDC discovery
and OAuthTokenSource::request_token. Validate issuer, discovered token_endpoint,
and direct token endpoints before connecting, reusing secure_endpoint for scheme
checks and the existing SSRF validation mechanism for address policy
enforcement.
In `@gears/system/oagw/oagw/src/infra/plugins.rs`:
- Around line 191-196: Update ApiKeyAuthPlugin::authenticate to map
HeaderName::from_lowercase failures to PluginError::Config instead of silently
succeeding. Change set_authorization to return Result<(), PluginError> and
propagate that result from all three callers, including oauth2_auth.rs at lines
300-304. Add tests covering invalid API-key header names and OAuth tokens
containing invalid header characters.

Add a resource-neutral GTS identifier for control-plane 404 responses.
domain_error_to_problem maps missing routes, upstreams, and plugins to gts::ERR_ROUTE_NOT_FOUND. A missing upstream or plugin therefore returns a route-specific "type" and can be misclassified by clients. Add a generic 404 identifier and use ERR_ROUTE_NOT_FOUND only for data-plane route failures.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Sort priority numerically.
route_priority renders u64 as a decimal string, and apply_filter_order in odata.rs compares field values with str::cmp. $orderby=priority desc therefore places priority 9 before priority 10. The domain model documents priority as "higher wins", so the returned order contradicts the routing semantics clients expect.
Render the value zero-padded to a fixed width so lexicographic order matches numeric order, or add a numeric comparison mode to FieldAccessor.
🐛 Proposed fix using a fixed-width rendering
fn route_priority(r: &Route) -> String {
- r.priority.to_string()
+ // Zero-pad to u64::MAX width so the string ordering used by
+ // `apply_filter_order` matches numeric ordering.
+ format!("{:020}", r.priority)
}Note that $filter=priority eq '10' must then compare against the same padded rendering, so prefer the FieldAccessor numeric-mode change if exact-match filtering on priority is part of the contract.

Apply allow_http_upstream during endpoint validation.
OagwConfig.allow_http_upstream documents support for http:// upstream targets. Line 613 rejects http unconditionally. ControlPlaneService has no configuration field, so an e2e configuration with allow_http_upstream: true still cannot create an HTTP upstream.
Pass the setting into the control plane and allow http only when it is enabled.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
The unknown sentinel merges separate rate-limit buckets.
In trusted mode client_ip returns "unknown" when the request carries no x-forwarded-for header, and the socket peer address is not used in that branch. For RateScope::Ip the key becomes i:{tenant}:unknown, so every such caller shares one bucket. One caller can then exhaust the limit for all other callers in the tenant. rate_key has the same pattern at line 1483, where a route without an id maps to r:unknown and shares a bucket with every other id-less route.
Fall back to the peer address for the IP scope.

Enforce route-rule uniqueness atomically.
This checks only the new route UUID. Two concurrent create_route calls can both pass check_route_match_unique, then insert different UUIDs for the same upstream, path, overlapping method, and priority. This violates the OagwRepository conflict contract and leaves ambiguous route configuration.
Make the conflict check and insert one atomic repository operation, keyed by the tenant and upstream.

Normalize custom plugin references before comparison.
A binding may use a bare UUID, but delete_plugin passes the stored GTS identifier to plugin_is_referenced. These raw-string comparisons treat the two valid forms as different. The reference check can return false and delete a plugin that an upstream or route still references.
Parse both values to UUIDs before comparing them.

Enforce SSRF checks for OAuth requests.
HttpClientConfig does not apply OagwConfig.ssrf_policy. Both OIDC discovery and OAuthTokenSource::request_token use the configured toolkit_http client for outbound requests. The discovered token_endpoint also bypasses secure_endpoint and receives no scheme or address validation. Validate issuer, discovered token, and direct token endpoints before each connection.

Apply OagwConfig.ssrf_policy through the configured toolkit_http client for
every OAuth outbound request, including OIDC discovery and
OAuthTokenSource::request_token. Validate issuer, discovered token_endpoint, and
direct token endpoints before connecting, reusing secure_endpoint for scheme
checks and the existing SSRF validation mechanism for address policy
enforcement.

Fail closed when credential-header construction fails.
ApiKeyAuthPlugin::authenticate can return Ok(()) when HeaderName::from_lowercase rejects a non-empty configured header_name. set_authorization can also return no error when HeaderValue::from_str rejects an OAuth token. The data-plane caller then continues without the configured credential header.
- Map the API-key header-name error to
PluginError::Config. - Make
set_authorizationreturnResult<(), PluginError>and propagate it from all three callers. - Add tests for invalid API-key header names and OAuth tokens with invalid header characters.

ApiKeyAuthPlugin::authenticate to map HeaderName::from_lowercase failures to
PluginError::Config instead of silently succeeding. Change set_authorization to
return Result<(), PluginError> and propagate that result from all three callers,
including oauth2_auth.rs at lines 300-304. Add tests covering invalid API-key
header names and OAuth tokens containing invalid header characters.
