📝 WalkthroughWalkthroughThe pull request adds the OAGW gateway as a complete Rust gear. It defines domain contracts, tenant-aware management services, REST routes, HTTP and WebSocket proxying, built-in plugins, rate limiting, SSRF protection, metrics, error handling, configuration, catalog publication, and end-to-end tests. ChangesOAGW Gateway
Priority: ➖ Normal Estimated code review effort: 5 (Critical) | ~120 minutes Change: Feature Merge Risk: 🟠 High · up to This change introduces a new API gateway with several issues that should be resolved before merge. Permission checks can be silently disabled at startup if the authorization service is unreachable, plugin read and delete operations can be authorized against the wrong plugin type, outbound request filtering can be bypassed with certain IPv6 address forms, and custom guard policies are not enforced. There are also framing, rate-limit inheritance, and concurrency issues that can affect proxied traffic correctness. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

Line 499 requires the first chunk within 120 ms of the request start. That budget also covers router dispatch, route resolution, and the upstream TCP connect. On a loaded CI runner the first chunk can exceed 120 ms even when the response is fully streamed, which fails the test for an unrelated reason.
Assert the relative property instead: the first chunk must arrive well before the last one. That still rejects a buffered implementation and does not depend on absolute machine speed.

In `@gears/system/oagw/oagw/src/api/rest/handlers.rs`:
- Around line 361-368: Update get_plugin, get_plugin_source, and delete_plugin
to load the plugin before authorization, then authorize using
OagwState::plugin_resource(plugin.plugin_type) rather than the caller-selected
or default kind from plugin_id. Preserve the existing READ or delete action for
each handler and ensure the loaded plugin is used for the subsequent response or
deletion.
- Around line 331-333: Update list_plugins to authorize each plugin’s
plugin_type before returning metadata, rather than relying only on
gts::GUARD_PLUGIN_BASE; filter out unauthorized kinds or enforce equivalent
per-kind checks before serialization, while preserving authorized plugin
results.
In `@gears/system/oagw/oagw/src/api/rest/proxy.rs`:
- Around line 299-315: Update client_ip to trust X-Forwarded-For only when the
connection peer from ConnectInfo<SocketAddr> is configured as trusted; otherwise
ignore the header and derive the address from ConnectInfo. Preserve the existing
first-value parsing for trusted peers and the Option<String> fallback behavior.
In `@gears/system/oagw/oagw/src/api/rest/state.rs`:
- Around line 63-65: Update OAGW initialization and the AuthZ resolver lookup so
a failed AuthZResolverClient lookup propagates its error and prevents startup,
rather than storing authz: None. Preserve authz: None only for test harnesses,
while keeping authorize’s existing behavior for that explicit test
configuration.
In `@gears/system/oagw/oagw/src/domain/merge.rs`:
- Line 39: Update the header selection logic around selected.headers to apply
the same ancestors-and-route hierarchical merge contract, preserving enforced
ancestor request and response header rules when a descendant shadows an alias.
Add and use a header sharing mode and merge function consistent with the
module’s existing configuration merging, or explicitly remove headers from the
hierarchical contract if they are not intended to inherit; do not leave the
direct clone/default path ignoring ancestors and route.
In `@gears/system/oagw/oagw/src/domain/model.rs`:
- Around line 246-247: Update Endpoint deserialization and normalization so an
omitted port remains distinguishable from an explicitly provided port, then
assign scheme.standard_port() when normalizing endpoints without a port. Remove
the fixed default_port behavior and ensure alias generation uses the normalized
scheme-specific port, including HTTP port 80.
- Around line 481-490: Update stricter_of to merge strategy, scope, algorithm,
budget, and response_headers using strict rules that preserve every enforced
ancestor rate-limit property, including Reject enforcement when a lower-rate
descendant uses Degrade. Add a regression test covering an enforced Reject
ancestor with a lower-rate Degrade descendant and verify over-limit requests
remain rejected.
In `@gears/system/oagw/oagw/src/domain/services.rs`:
- Around line 344-362: Update resolve_proxy_target so route matching returns and
preserves the upstream that owns the matched route, rather than always pairing
the route with selected. Ensure ProxyTarget.upstream and route come from the
same candidate while retaining the existing not-found behavior and
effective_config processing.
In `@gears/system/oagw/oagw/src/domain/tenant.rs`:
- Around line 13-16: Change the tenant hierarchy resolution contract around
ancestor_chain so hierarchical lookup failures cannot silently degrade to a flat
[tenant_id] chain: return an error or use a last-known verified chain. Preserve
[tenant_id] behavior specifically for FlatTenantDirectory, and update
resolve_proxy_target/effective_config handling so failed hierarchy resolution
does not omit ancestor policies.
In `@gears/system/oagw/oagw/src/gear.rs`:
- Around line 103-109: Update the AuthZResolverClient lookup in OagwState
initialization to fail closed: propagate or return an initialization error when
ctx.client_hub().get::<dyn AuthZResolverClient>() fails, rather than logging a
warning and constructing PolicyEnforcer without authorization. Preserve the
successful client path that creates PolicyEnforcer.
In `@gears/system/oagw/oagw/src/infra/metrics.rs`:
- Around line 168-177: Update record_rate_limit to accept and label metrics with
the matched route pattern rather than the normalized raw request path, and
update DataPlaneService::enforce_rate_limit to pass that pattern through.
Preserve the existing host labels and metric recording behavior while ensuring
path cardinality remains bounded.
In `@gears/system/oagw/oagw/src/infra/plugin/oauth2_client_cred_auth.rs`:
- Around line 175-180: Update the token_endpoint and issuer_url handling around
parse_url to validate that each parsed URL uses HTTPS before assigning it to
oauth_config; reject non-HTTPS schemes, including HTTP, while preserving the
existing parsing error propagation.
In `@gears/system/oagw/oagw/src/infra/proxy/connector.rs`:
- Around line 164-182: Update alias::validate_host’s IpAddr::V6 handling to
detect IPv4-mapped IPv6 addresses and apply the existing IPv4 SSRF
classification and allow_loopback, allow_private, and related policy checks to
the embedded address before the IPv6-only checks. Preserve current behavior for
non-mapped IPv6 addresses and reject mapped loopback, private, or link-local
destinations when their corresponding policies disallow them.
In `@gears/system/oagw/oagw/src/infra/proxy/service.rs`:
- Around line 621-633: Update the custom plugin handling in the binding
resolution flow so custom guard bindings return PluginNotFound when no
interpreter is available, rather than touching the repository and continuing.
Preserve the existing skip behavior for non-guard custom plugin bindings, using
the binding guard classification and the existing PluginNotFound error path.
In `@gears/system/oagw/oagw/src/infra/proxy/websocket.rs`:
- Around line 177-197: Update the rejected-response handling before constructing
HandshakeResult::Rejected so ProxyResponseHead headers replace the upstream
Content-Length with the actual body.len(), covering both truncation at
MAX_REJECT_BODY_BYTES and early upstream EOF. Preserve the existing body-reading
and error behavior.
In `@gears/system/oagw/oagw/src/infra/storage.rs`:
- Around line 149-163: Serialize each uniqueness check and its subsequent write
with one shared synchronization mechanism. Update the UpstreamStore insert and
replace flows, the plugin name insertion flow, and ensure_match_unique so
validation and mutation occur under the same write lock, preventing concurrent
requests from creating duplicate tenant aliases, plugin names, or matches.
- Around line 209-214: Add secondary indexes to the storage structure and
maintain them whenever upstreams or routes are created, updated, or removed: use
a tenant-and-alias index for find_by_alias and an upstream-to-route-ID index for
list_by_upstream, replacing full-map scans while preserving existing results.
Update unlinked_plugins to build the referenced-plugin set once, then compare
every plugin against that set instead of repeatedly calling
references_to_plugin.

Authorize the stored plugin kind.
plugin_id accepts a bare UUID or a caller-selected GTS base. The handlers default a bare UUID to PluginKind::Guard and authorize before loading the plugin. A caller with only guard permissions can therefore read an auth plugin, expose its source_code, or delete it within the same tenant.
Load the plugin first, then authorize with OagwState::plugin_resource(plugin.plugin_type) in get_plugin, get_plugin_source, and delete_plugin.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
A truncated reject body keeps the upstream Content-Length.
Line 183 caps the read at MAX_REJECT_BODY_BYTES, and the loop stops there. The parsed headers still carry the upstream Content-Length, and HandshakeResult::Rejected returns both. The service relays that head unchanged, so a client receives a declared length that is larger than the body and waits for bytes that never arrive. The same mismatch occurs when the upstream closes early and the loop breaks at Line 187.
Set Content-Length to the actual body length before returning.

Guard the uniqueness checks and the insert with one lock.
Each insert scans the map, then writes under a fresh random UUID key. The scan and the write are separate operations, and DashMap only makes a single entry atomic. Two concurrent requests that create the same (tenant_id, alias) both pass the scan, then both insert under different ids. The per-tenant alias invariant then breaks, and find_by_alias (Line 209) returns whichever entry the iteration reaches first. The same race applies to the plugin name check (Line 340), to ensure_match_unique (Line 230 and Line 242), and to the alias check in replace (Line 172).
Serialize the check-then-write sequence. One option is a std::sync::Mutex<()> write lock held across validation and insertion. A second option is a secondary uniqueness index keyed by (tenant_id, alias) written with entry().or_insert() so the reservation itself is atomic.

Serialize each uniqueness check and its subsequent write with one shared
synchronization mechanism. Update the UpstreamStore insert and replace flows,
the plugin name insertion flow, and ensure_match_unique so validation and
mutation occur under the same write lock, preventing concurrent requests from
creating duplicate tenant aliases, plugin names, or matches.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
Index the hot-path lookups instead of scanning every entry.
find_by_alias and list_by_upstream iterate the whole map. Proxy resolution calls find_by_alias once per tenant in the ancestor chain, and match_route calls list_by_upstream once per candidate upstream. Every proxied request therefore costs O(total upstreams + total routes) across all tenants. unlinked_plugins (Line 136) is worse: it calls references_to_plugin per plugin, which is O(plugins × (upstreams + routes)) on each garbage-collection sweep.
Add secondary indexes, for example DashMap<(Uuid, String), Uuid> for tenant alias lookup and DashMap<Uuid, HashSet<Uuid>> for routes per upstream. For the sweep, build the reference set once and compare all plugins against it.
