📝 WalkthroughWalkthroughThe PR adds the OAGW crate with tenant-scoped management APIs, plugin execution, proxy routing, policy enforcement, streaming transport, in-memory storage, configuration, and gear integration. ChangesOAGW gateway
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔴 Critical · up to This PR adds gateway routing and proxy behavior, but the current head still has merge-blocking issues: the default test build cannot resolve a referenced type, and request forwarding and authentication can allow reserved-header overrides, cleartext OAuth credentials, SSRF through mapped addresses, caller-controlled API-key query values, quota bypass, and cross-tenant route updates. These can cause failed builds, insecure or incorrect upstream requests, tenant-isolation failures, and availability abuse, so the PR is not safe to merge until fixed.

a leading '-' is consumed before checking that the following character is an
ASCII digit. Preserve digit-starting literals and reject '-' when it is not
followed by a digit, allowing expressions such as priority gt -1 to parse
successfully.
In `@gears/system/oagw/oagw/src/domain/model.rs`:
- Around line 555-567: Update PluginRef serialization to match its manual
deserialization wire format: serialize Id as a bare plugin-id string and Binding
as an object containing plugin_ref with optional config, rather than externally
tagged Id/Binding objects. Use either a manual Serialize implementation or
serde’s untagged representation while preserving the existing field names and
omission of absent config.
In `@gears/system/oagw/oagw/src/domain/services.rs`:
- Around line 479-490: Update PluginRepository::insert, specifically
MemoryPluginRepository::insert, to atomically reject an existing record with the
same tenant_id, plugin_type, and name before insertion, while preserving the
existing (tenant_id, id) validation and conflict behavior.
In `@gears/system/oagw/oagw/src/domain/validation.rs`:
- Around line 288-304: Update validate_rate_limit to reject cost values below 1
and values greater than the effective bucket capacity, using the configured
burst capacity when present and the sustained rate otherwise. Add DomainError
validation messages consistent with the existing checks while preserving the
current sustained-rate and burst-capacity validation.
In `@gears/system/oagw/oagw/src/infra/plugin/apikey_auth.rs`:
- Line 36: Update the name normalization around ApiKeyLocation so configured
query parameter names retain trimming but preserve their original case, while
header names may continue using lowercase normalization. Ensure a configured
query name such as ApiKey is injected unchanged for query authentication.
- Line 106: Update the query-parameter handling around request.query.push to
remove all existing pairs whose name matches the configured credential parameter
before appending the resolved credential value, ensuring only the
credential-store value remains and is first if duplicates are possible.
In `@gears/system/oagw/oagw/src/infra/plugin/oauth2_client_cred_auth_tests.rs`:
- Around line 579-580: Update the fips_free test setup using FetchTokenExchanger
to import the type from the sibling oauth2_client_cred_auth module, or qualify
it with that module path; keep the existing constructor and testing HTTP
configuration unchanged.
- Line 547: Update the Tokio test around MockServer to use the asynchronous API:
replace MockServer::start() with MockServer::start_async().await and await the
mock_async(...) setup calls, preserving the existing test behavior without
blocking the Tokio worker.
In `@gears/system/oagw/oagw/src/infra/plugin/oauth2_client_cred_auth.rs`:
- Around line 118-129: Update the OAuth2 configuration parsing around parse_url,
token_endpoint, and issuer_url to reject any configured URL whose scheme is not
https before accepting it. Apply the same validation to both endpoint types and
preserve the existing mutually exclusive and required-field checks; only permit
plaintext URLs if the established allow_http_upstream deployment flag explicitly
governs this path.
In `@gears/system/oagw/oagw/src/infra/proxy/headers.rs`:
- Around line 123-124: Update gears/system/oagw/oagw/src/infra/proxy/headers.rs
lines 123-124 so apply_set and apply_add cannot restore reserved request
headers, and write the selected endpoint Host header last. Also update lines
156-158 to reject or skip hop-by-hop and framing response-header names in set
and add.
- Around line 110-113: Update the inbound header filtering at
gears/system/oagw/oagw/src/infra/proxy/headers.rs lines 110-113 to parse
Connection tokens and remove every nominated header, while preserving required
connection/upgrade handshake headers. Apply the same token parsing and
nominated-header removal to the upstream response filtering at
gears/system/oagw/oagw/src/infra/proxy/headers.rs lines 151-154 before returning
headers.
In `@gears/system/oagw/oagw/src/infra/proxy/ratelimit.rs`:
- Around line 180-182: Update the rate-limit bucket management around sweep and
check so MAX_BUCKETS is enforced as an actual map ceiling, rather than merely
triggering retain after the threshold is reached. Run sweeping on a time
interval instead of every check once the threshold is exceeded, while preserving
idle-bucket removal and avoiding a full bucket scan on each request.
- Line 117: Update the RateScope::Ip keying used by enforce_rate_limit and
RateLimiter::key to derive the client IP from the trusted peer address; do not
use unvalidated inbound X-Forwarded-For values. If proxy headers must be
supported, accept them only when the request originates from a configured
trusted proxy, otherwise fall back to the trusted peer IP.
In `@gears/system/oagw/oagw/src/infra/proxy/route_match.rs`:
- Line 67: Reverse the route-ID comparison in the ordering chain used by max_by
so a complete tie selects the lower UUID, while preserving prefix and priority
ordering. Add a test covering equal-prefix, equal-priority routes with different
IDs and assert that the route with the lower ID is selected.
In `@gears/system/oagw/oagw/src/infra/proxy/ssrf.rs`:
- Around line 80-94: Update is_local_address to canonicalize parsed IpAddr
values with to_canonical() before range checks, ensuring IPv4-mapped IPv6
addresses use IPv4 validation; also include is_multicast() in both IPv4 and IPv6
checks.
In `@gears/system/oagw/oagw/src/infra/storage.rs`:
- Around line 179-190: Update MemoryRouteRepository::update so its mutable row
lookup matches both route.tenant_id and route.id, preventing a cross-tenant
replacement while preserving the existing NotFound behavior when no scoped row
matches.

Minor comments:
In `@gears/system/oagw/oagw/src/api/rest/handlers_tests.rs`:
- Line 466: Remove the redundant as u64 casts from the page_info limit
expressions at all three occurrences, including the code near the limit
assignments associated with lines 466, 522, and 830. Keep the existing
as_u64().unwrap_or_default() behavior unchanged.
In `@gears/system/oagw/oagw/src/domain/dto.rs`:
- Around line 116-117: Update the documentation near compare to describe the
implemented absent-as-null behavior: missing fields are substituted with
Value::Null and may match null comparisons, including eq and ne semantics.
Remove the contradictory claim that absent fields never match, while preserving
the comparison implementation and its inline comment.
In `@gears/system/oagw/oagw/src/domain/validation.rs`:
- Around line 598-601: Update the resource_gts_id call in the validation
error-detail construction to pass UPSTREAM_TYPE instead of ROUTE_TYPE, while
preserving the existing upstream_id argument and message behavior.
- Around line 535-540: Restrict the cleartext opt-in early return in the
validation logic to apply only when the requested protocol is Protocol::Http,
preserving the existing scheme comparison for Protocol::Grpc and other
protocols. Update the condition around allow_cleartext and first.scheme so
HTTP/WS endpoints cannot bypass the expected-scheme check for gRPC upstreams.
In `@gears/system/oagw/oagw/src/infra/proxy/endpoint.rs`:
- Around line 264-270: Update parse_target_host to normalize bracketed IPv6
literals by removing the surrounding brackets before validation and comparison
with Endpoint.host. Preserve rejection of malformed or unrelated bracketed
values, and ensure valid unbracketed and bracketed IPv6 addresses follow the
same matching path.
In `@gears/system/oagw/oagw/src/infra/proxy/forward_tests.rs`:
- Around line 409-424: Strengthen the forwarding test around ForwardRequest and
the upstream mock so endpoint selection is observable: require the mock to match
the expected host header for the localhost endpoint, while retaining the
existing method and path matching. Keep the status assertion, ensuring endpoint
0 cannot satisfy the request if target_host pinning is ignored.
In `@gears/system/oagw/oagw/src/infra/proxy/resolver.rs`:
- Around line 104-105: Update the AliasResolver::resolve rustdoc in
gears/system/oagw/oagw/src/infra/proxy/resolver.rs#L104-L105 to document
DomainError::RouteNotFound instead of UnknownTargetHost. In
gears/system/oagw/oagw/src/infra/proxy/resolver_tests.rs#L141-L143, rename the
test to an_unknown_alias_is_a_route_not_found and correct its documentation
status from 400 to 404.
In `@gears/system/oagw/oagw/src/infra/storage.rs`:
- Around line 283-296: Update MemoryPluginRepository::insert to reject an
existing plugin with the same tenant_id, plugin_type, and name, performing this
validation while holding the existing write lock. Preserve the current
ID-conflict error behavior and return a DomainError::Conflict before pushing
duplicates.
In `@gears/system/oagw/oagw/src/lib.rs`:
- Around line 14-20: Update the module documentation in
gears/system/oagw/oagw/src/lib.rs lines 14-20 to describe the implemented proxy
data plane, forwarding, streaming, rate limiting, and CORS; remove those items
from the out-of-scope list, the 503 proxy-route claim, and the
data-plane-placeholder wording for infra. Update
gears/system/oagw/oagw/src/infra/mod.rs lines 3-5 so the proxy module is
documented as implementing the data plane rather than serving as a placeholder.

The plugin-source response declares text/x-starlark but sends a JSON body. get_plugin_source sets Content-Type: text/x-starlark; charset=utf-8 and then serializes PluginSourceResponseDto with Json, so the body is a JSON object while the header advertises Starlark source. The OpenAPI document declares the same operation as a JSON schema response, so the document and the wire header also disagree. A client that trusts either one parses the wrong media type.
Pick one contract and make both sites agree.
gears/system/oagw/oagw/src/api/rest/handlers.rs#L482-L492: either return the rawplugin.source_codestring as the body with thetext/x-starlarkcontent type, or keep theJson(dto)body and setapplication/json.gears/system/oagw/oagw/src/api/rest/routes.rs#L400-L404: if the handler serves raw Starlark, replacejson_response_with_schema::<PluginSourceResponseDto>with aResponseSpecwhosecontent_typeistext/x-starlark; if the handler serves JSON, keep this declaration and drop the Starlark header.
Note that handlers_tests.rs at Line 839 asserts both the text/x-starlark prefix and a source_code JSON field, so it currently encodes the mismatch and needs updating with the fix.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
The negative-number branch is unreachable, so $filter rejects negative literals.
At this point c is the peeked character and has not been consumed. chars.peek() therefore returns the same '-' character, and '-'.is_ascii_digit() is false. The guard c == '-' && chars.peek().is_some_and(char::is_ascii_digit) can never be true.
A filter such as priority gt -1 falls through to the final arm at Line 405 and fails with "$filter contains an unexpected character '-'".
Consume the '-' first, then inspect the next character.

Implement a wire-compatible Serialize implementation for PluginRef.
PluginRef derives externally tagged Serialize, but its manual Deserialize accepts only a bare string or an object with plugin_ref and optional config. Therefore, serializing PluginsConfig through Upstream or Route produces {"Id":...} or {"Binding":...}, which the deserializer rejects. Add a manual Serialize implementation or apply #[serde(untagged)] to the derived serializer.

cost is not validated, so two reachable configurations break rate limiting.
RateLimitConfig::cost is a u64 with a serde default of 1 (gears/system/oagw/oagw/src/domain/model.rs Lines 455-456). This function checks only the sustained rate and the burst capacity.
cost: 0 makes every request consume no tokens, so the configured limit never applies. A cost greater than the effective bucket capacity makes every request exceed the limit, so the upstream rejects all traffic permanently. Both values pass validation today.
Bound cost against the effective capacity.

Use a trusted client IP for RateScope::Ip.
The handler copies inbound headers into ProxyContext without validating X-Forwarded-For. enforce_rate_limit passes that value to RateLimiter::key, which uses it as the bucket identity. A caller can send a new value per request and bypass the IP-scoped quota. Derive the client IP from the trusted peer address, or process X-Forwarded-For only from configured trusted proxies.

MAX_BUCKETS does not bound the map, and the sweep runs on every request once the threshold is reached.
sweep returns early while the map holds fewer than MAX_BUCKETS entries. Above that size it runs retain on every check call. retain only drops buckets that were idle for IDLE_BUCKET_TTL (one hour). With an unbounded key space, such as RateScope::Ip, active traffic keeps most buckets fresh. Two consequences follow:
- The map grows past
MAX_BUCKETS, so the constant is not the ceiling the doc comment on Line 27 describes. - Each request then walks 100 000 entries and locks each bucket mutex on the proxy hot path.
Sweep on a time interval instead of on size, and enforce the ceiling explicitly.

Rust standard library IpAddr to_canonical IPv4-mapped IPv6 Ipv4Addr Ipv6Addr is_multicast is_loopback is_link_local contract
💡 Result:
In the Rust standard library (stable since 1.75.0), the to_canonical method on IpAddr and Ipv6Addr is designed to handle address mapping normalization [1][2]. IpAddr::to_canonical This method converts an IpAddr to an IpAddr::V4 variant if it is an IPv4-mapped IPv6 address [1][3]. If the address is already an IPv4 address or a standard IPv6 address (non-mapped), it returns the address as-is [1][3]. This allows for a uniform representation when dealing with networks that may mix IPv4 and IPv4-mapped IPv6 addresses [1][2]. Classification Methods The Rust standard library provides several methods on Ipv4Addr and Ipv6Addr (and by extension, IpAddr) to classify address types [4][5][6]: is_loopback: Returns true if the address is a loopback address [4][5]. For IPv4, this checks the 127.0.0.0/8 range; for IPv6, it specifically checks for::1 [4][5]. Note that calling is_loopback on an IPv4-mapped IPv6 address that represents a loopback address will return false, while calling to_canonical on that same address and then checking is_loopback will return true [1][5]. is_multicast: Returns true if the address is a multicast address [4][5][6]. This covers the 224.0.0.0/4 range for IPv4 and the ff00::/8 range for IPv6 [4][5]. is_link_local: Returns true if the address is within the link-local range (169.254.0.0/16 for IPv4 and fe80::/10 for IPv6) [4][5]. IPv4-Mapped IPv6 Addresses IPv4-mapped IPv6 addresses (defined in RFC 4291) have the form::ffff:a.b.c.d [5][7]. The method Ipv6Addr::to_ipv4_mapped returns an Option if the address is an IPv4-mapped IPv6 address [5][7]. The method Ipv6Addr::to_ipv4 converts an IPv4-mapped IPv6 address to an Ipv4Addr, but it also converts the IPv6 loopback address (::1) to an IPv4 loopback address (0.0.0.1) [5][7]. Use to_ipv4_mapped if this conversion of::1 is undesirable [5][7]. Contract and Usage The methods generally behave as const-stable functions [1][2]. When checking properties like is_loopback, developers should be aware that IPv6 addresses containing an embedded IPv4 address do not automatically inherit the semantic properties of the embedded IPv4 address until they are converted to the canonical IPv4 form [1][5]. Therefore, for consistent classification of IPv4-mapped addresses, developers should use to_canonical before performing property checks [1][3].

Canonicalise IPv4-mapped IPv6 literals before the range checks. IpAddr::to_canonical() converts mapped IPv6 addresses to IpAddr::V4. Without it, is_local_address can admit mapped loopback and link-local targets. Add is_multicast() checks for both address families. The repository requires Rust 1.95, so the API is supported.
