Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR introduces concrete security, correctness, abuse-prevention, and availability risks: tenant-controlled endpoints may bypass SSRF protection, credentials may appear in error responses, rate limits can be reset or bypassed, and several request and connection limits are not enforced consistently.

117-121: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winDrop the unused pingora dependencies in this PR.
The deviation records that
pingora-coreandpingora-proxyare unused because the outbound path usesreqwest. Unused dependencies enlarge the build and the dependency attack surface, and a reader ofCargo.tomlcannot tell that the proxy engine does not use them. Remove them now rather than deferring to a later hygiene pass, or state the release that will remove them.I can prepare the manifest change and confirm no source file references either crate. Do you want me to open an issue to track it?

Inline comments:
In `@gears/system/oagw/oagw/docs/reviews/slice-5-data-plane.md`:
- Line 26: Escape the pipe character in the inline code span containing
“strategy: queue|degrade” so the Markdown table remains four columns and the
disposition stays in its intended column.
In `@gears/system/oagw/oagw/src/api/error.rs`:
- Around line 182-191: Update upstream_error to accept the upstream content type
and set it on the returned response alongside X-OAGW-Error-Source, preserving
the relayed body’s correct media type; alternatively, revise the function’s
documentation to state that only the source header is relayed.
In `@gears/system/oagw/oagw/src/api/rest/body.rs`:
- Around line 28-33: Update Oagw::register_rest to layer the existing
Arc<OagwConfig> into the management router, or pass its max_body_size_bytes
through router state, so JsonBody::from_request receives the configured
management body limit instead of falling back to DEFAULT_BODY_LIMIT_BYTES.
In `@gears/system/oagw/oagw/src/api/rest/handlers.rs`:
- Around line 50-62: Update list_upstreams, list_routes, and list_plugins to
apply each query’s ListParams::apply to the service results before calling
list_response, including $filter, $orderby, $top, and $skip and the default
page-size cap. Propagate validation errors, then pass the transformed rows to
list_response so selection, projection, and serialization operate on the
filtered/paginated data.
In `@gears/system/oagw/oagw/src/api/rest/proxy.rs`:
- Around line 491-534: Update the WebSocket relay around the relay loop and
relay_socket call site to enforce OagwConfig::idle_timeout(): pass
stack.config.idle_timeout() into relay_socket, add a tokio::select! timeout
branch using that duration, and terminate the relay when the timeout elapses
while preserving existing close/error handling.
In `@gears/system/oagw/oagw/src/config.rs`:
- Around line 29-39: Implement an explicit Default for SsrfPolicy that
initializes enabled to true while retaining empty allowed_segments and
blocked_segments; update the field documentation to describe disabling SSRF
checks as an explicit opt-out.
In `@gears/system/oagw/oagw/src/domain/error.rs`:
- Line 375: Update the retry-delay calculation around value.as_secs().max(1) to
round fractional durations up to the next whole second, while retaining a
minimum delay of one second.
In `@gears/system/oagw/oagw/src/domain/merge.rs`:
- Around line 229-235: Resolve the inconsistency in the merge logic around
merged.enabled and the inherited-policy comment: if disabled descendants must
remain disabled, gate the ancestor/descendant enabled union on
descendant.enabled; otherwise revise the comment to accurately describe the
existing OR behavior. Preserve the existing credential and wildcard-origin
handling.
- Around line 103-113: Update pick_burst to resolve each BurstConfig’s effective
capacity, including the sustained-rate fallback when capacity is omitted, before
taking the minimum; preserve the stricter ancestor limit in the merged result.
Revise the assertion covering this case near the existing merge tests to expect
the stricter effective capacity instead of the current loose result.
In `@gears/system/oagw/oagw/src/domain/services/management.rs`:
- Around line 137-138: In the update flow, call validate_upstream_body before
validate_upstream_update, then assign the derived or normalized alias to next
before performing the immutability comparison. Preserve rejection of genuine
renames while allowing omitted aliases to be derived consistently with
create_upstream.
In `@gears/system/oagw/oagw/src/domain/services/proxy.rs`:
- Around line 459-472: The query-parameter policy is enforced inconsistently:
enforce_match_rules rejects parameters that allowed_query is designed to drop,
preventing documented behavior. Remove the query-allowlist rejection loop from
enforce_match_rules so allowed_query remains the single enforcement point,
dropping unlisted parameters while an empty query_allowlist forwards no query
parameters; add coverage for an empty allowlist with a request containing a
query string.
In `@gears/system/oagw/oagw/src/domain/validation.rs`:
- Around line 471-475: Update the validation error in the normalized alias
comparison to interpolate only the existing and next alias values, not the full
Upstream structs. Preserve the immutable-alias validation behavior and message
context while preventing auth.config, tenant_id, and other internal fields from
reaching the client.
In `@gears/system/oagw/oagw/src/gear.rs`:
- Around line 255-256: Update the route construction around gear_relative and
documented so only the OAGW subtree is nested under API_MOUNT; build and nest
the OAGW routes before merging with the incoming router, then merge the mounted
subtree into router so existing host routes are not republished under /api.
In `@gears/system/oagw/oagw/src/infra/cors.rs`:
- Around line 132-143: The evaluate decision path must guard against a
CorsConfig containing both "*" in allowed_origins and allow_credentials enabled,
including configs supplied directly through effective policy resolution. Update
evaluate or its immediate policy decision logic to reject the policy or disable
credentials before SimpleCors::apply can echo an origin with credentials;
preserve normal wildcard behavior when credentials are disabled and
explicit-origin credential behavior for valid configurations.
In `@gears/system/oagw/oagw/src/infra/http.rs`:
- Around line 128-141: Update OutboundClient::new to use the proxy_timeout
parameter and configure the reqwest Client builder with a read timeout via
read_timeout(proxy_timeout), preserving the existing connection and pool timeout
settings.
In `@gears/system/oagw/oagw/src/infra/metrics.rs`:
- Around line 229-230: Update the drop logic to obtain the pre-decrement counter
value from fetch_sub rather than a separate counter.load, then derive the
current in-flight count from that returned value while preserving the existing
gauge update behavior and atomic ordering.
In `@gears/system/oagw/oagw/src/infra/proxy.rs`:
- Around line 708-709: Remove both insert_header calls for “connection” and
“upgrade” in connect_websocket, relying on RequestBuilder’s existing header
handling to avoid sending duplicate upgrade headers.
In `@gears/system/oagw/oagw/src/infra/ratelimit.rs`:
- Around line 163-169: Update the shape reconciliation logic in the bucket
charging path so changing RateShape does not reset bucket.tokens to
shape.capacity; instead scale the current token level proportionally onto the
new capacity while preserving refill timing and preventing alternating
configurations from replenishing the counter. Add a test that charges one
RateKey with two different configurations in alternation and verifies the
counter eventually exhausts.
- Around line 149-151: Replace the all-bucket reset in the overflow branch of
the bucket management logic with selective eviction: remove already-replenished
buckets first, then apply a bounded partial eviction if capacity is still
exhausted, preserving existing counters for unaffected keys.

Escape the pipe inside the code span.
The | in `strategy: queue|degrade` is parsed as a table cell delimiter, even inside a code span. The row therefore renders with five cells instead of four, and the disposition text shifts out of its column. Escape the pipe.

Set the content type for the relayed upstream body.
(status, body).into_response() labels the response text/plain; charset=utf-8 because body is a String. Upstream error bodies are usually JSON, so clients that branch on the content type mis-handle the relayed payload. The doc comment also says the upstream headers are preserved, but only X-OAGW-Error-Source is set.
Accept the upstream content type and set it on the response, or state in the doc comment that only the source header is relayed.

Apply all parsed list options before list_response. ListQuery parses $filter, $orderby, $top, and $skip, and ListParams::apply implements them. However, list_upstreams, list_routes, and list_plugins pass raw service results to list_response, which only uses query.selected(). The advertised options therefore do not affect these responses, and the default page-size cap is not applied. Apply the options to the serialized rows and propagate validation errors before projection and serialization.

Apply the configured idle timeout to the WebSocket relay.
The relay loop ends only when one side closes or errors. An idle tunnel holds the client socket, the upstream socket, and this task for an unbounded time. Idle tunnels therefore accumulate.
OagwConfig::idle_timeout() already states the intended bound (see src/config.rs Lines 115-119) and no code on this path uses it. Add a timeout branch to the select! and pass the configured duration into relay_socket.

reqwest ClientBuilder read_timeout inactivity per-read timeout streaming body
💡 Result:
In reqwest, the ClientBuilder::read_timeout(Duration) method provides an inactivity timeout mechanism designed to detect stalled connections during streaming operations [1][2][3]. Key characteristics of read_timeout include: * Recurring Timeout: Unlike the total timeout() option—which sets a hard deadline for the entire request/response lifecycle—the read_timeout is a recurring, per-operation timeout [1][2][4]. * Reset Behavior: It resets every time a successful read operation completes (i.e., when data is received from the server) [1][5]. If no data is received within the specified duration, the stream returns an error [6][4]. * Scope: It applies to the entire duration of the request's lifecycle after the initial connection is established, including waiting for response headers and subsequent body chunks [2][4]. Note that it does not distinguish between phases; if you are sending a large request body, the read_timeout may also apply during the writing/upload phase, as it tracks inactivity in the underlying IO [7]. * Definition of "Read": A read corresponds to an IO operation receiving data from the remote peer [4]. It is not a measurement of throughput or total data size, but rather an "inactivity" timer that ensures the connection is still actively transferring data [2][4]. In summary, read_timeout is the correct tool for streaming large bodies where the total duration is unknown, as it ensures the connection is not silently dropped or stalled without error [2][5]. If you require a strict upper bound on the entire request duration, use ClientBuilder::timeout() instead, or combine both if both "total deadline" and "inactivity" protection are required [1][8][6].

reqwest 0.13.3 ClientBuilder read_timeout pool_idle_timeout docs.rs
💡 Result:
In reqwest version 0.13.3, both read_timeout and pool_idle_timeout are available via the ClientBuilder struct [1][2]. read_timeout: This method was added in reqwest 0.13.3 [2][3]. It accepts a std::time::Duration and sets a recurring timeout for each read operation [4][2]. If a read operation does not complete within the specified duration, the request will error [4]. The timeout timer resets after each successful read, making it effective for detecting stalled downloads or streaming responses [4]. pool_idle_timeout: This is a standard configuration method on ClientBuilder that allows you to specify how long an idle connection is kept in the client's internal connection pool before being closed [5]. It accepts a std::time::Duration. It is part of the broader pool configuration suite, which also includes methods like pool_max_idle_per_host [5]. To use these, you would configure them when building your client: use std::time::Duration; use reqwest::Client; let client = Client::builder.read_timeout(Duration::from_secs(30)).pool_idle_timeout(Duration::from_secs(90)).build.unwrap;

Bound the response body with an inactivity timeout.
OutboundClient::send returns after the headers, and the proxy forwards bytes_stream() without another timeout. pool_idle_timeout only closes idle pooled connections. Add .read_timeout(proxy_timeout) and rename _proxy_timeout. The timeout resets after each successful read, so active event streams can continue while stalled bodies terminate.

Read the in-flight count from fetch_sub, not from a separate load.
drop reads the counter and then decrements it in two separate atomic operations. Two guards for the same host that drop concurrently both observe the same pre-decrement value. Both then record the same current, while the counter falls by two. The gauge keeps a non-zero in-flight count for a host that has no in-flight request, and nothing corrects it until the next enter or drop for that host.
Use the value that fetch_sub returns. It makes the read and the decrement one atomic operation and matches the enter path at Line 153.

reqwest RequestBuilder header append or replace existing headers map
💡 Result:
In the reqwest library's RequestBuilder, the.header method always appends new header values to the existing set rather than replacing them [1][2]. If you call.header multiple times with the same header name, the resulting request will contain multiple values for that header, which may cause unexpected behavior depending on how the receiving server handles multiple header values [3]. Because RequestBuilder does not provide a built-in method to remove or replace a single header once it has been added, you must manage header replacement manually [3]. To replace a header, you should use the following approach: 1. Create a HeaderMap manually. 2. Insert your desired header value into the HeaderMap. 3. Pass this HeaderMap to the request using the.headers method [1][4]. Note that while.header appends, the.headers method merges the provided HeaderMap with any headers already present in the RequestBuilder [1]. If you need to ensure a completely clean state for specific headers, it is often best to construct your headers in a HeaderMap before starting the request builder chain: use reqwest::header::HeaderMap; use reqwest::Client; let mut headers = HeaderMap::new; headers.insert("Content-Type", "application/json".parse.unwrap); let client = Client::new; let res = client.post("https://example.com").headers(headers) // Sets (and replaces) headers defined in the map.send.await?; If you have already started building the request and need to modify headers, you may need to build the request in a more granular way or handle the header map logic before finalizing the builder [3]. There is no direct.replace_header equivalent in the public API [3].

reqwest 0.13 RequestBuilder headers HeaderMap header append source
💡 Result:
In reqwest, the RequestBuilder and HeaderMap types work together to manage HTTP headers. The following explains how to use append and related methods effectively: RequestBuilder Header Management The RequestBuilder API provides two primary ways to add headers to a request: 1. header<K, V>(self, key: K, value: V): This method adds an individual header to the request [1][2]. If you call.header multiple times with the same header name, the values are appended to that header, rather than replacing the previous value [3]. 2. headers(self, headers: HeaderMap): This method accepts a HeaderMap and merges it into the existing headers on the request [1][2]. HeaderMap::append The HeaderMap type is a specialized multimap that supports multiple values for a single header name [4][5]. The.append method is used to add a value to the list of values associated with a specific header name [4][6]: use reqwest::header::{HeaderMap, HOST}; let mut map = HeaderMap::new; map.insert(HOST, "world".parse.unwrap); // After insertion, append adds a new value to the same key map.append(HOST, "earth".parse.unwrap); // You can retrieve all values associated with the key let values = map.get_all(HOST); let mut i = values.iter; assert_eq!("world", *i.next.unwrap); assert_eq!("earth", *i.next.unwrap); Key Considerations -.append behavior: If the header key does not previously exist in the map,.append functions similarly to an insert and returns false [4][6]. If the key is already present, the new value is pushed to the end of the list of values for that key [4][7]. - HeaderMap vs. insert: Unlike.append, the.insert method will overwrite any existing values associated with that specific key [4][6]. - Client Defaults: If you are using ClientBuilder::default_headers, be aware that some implementations of default header logic may interact differently with multi-value headers than the RequestBuilder [8][9]. Always verify if you need to replace or extend existing headers based on your specific use case [8].

Remove the duplicated upgrade headers from the engine.
RequestBuilder::headers merges the supplied HeaderMap, and RequestBuilder::header appends values for existing names. connect_websocket therefore sends duplicate Connection and Upgrade values. Delete both insert_header calls.

Table overflow clears every counter, so key cycling resets all victims' limits.
buckets.clear() removes every bucket, not only the pressure. A caller that cycles distinct keys (a fresh source address per request under scope: ip) drives the table to MAX_BUCKETS repeatedly. Each overflow returns all other tenants' counters to a full bucket, so their limits stop binding.
Evict selectively instead. Drop the buckets that are already replenished, and only then fall back to a bounded partial eviction.

if !buckets.contains_key(&key) && buckets.len() >= MAX_BUCKETS {
- buckets.clear();
+ // Only fully replenished buckets carry no enforcement state, so
+ // they are the safe eviction candidates.
+ buckets.retain(|_, bucket| {

Shape reconciliation lets two configs on one counter key reset the bucket on every request.
RateKey carries only the scope identity. It does not carry the rate posture. With scope: tenant (or global, ip, user), one counter key is shared by every upstream and route of that tenant. If two of them configure different rates or windows, bucket.shape != shape holds on each alternating request, and bucket.tokens returns to shape.capacity. The limit then never binds.
Reconcile without restarting full. Scale the current level onto the new capacity.
🔒️ Proposed fix
if bucket.shape != shape {
- bucket.capacity = shape.capacity;
- bucket.refill_per_second = shape.refill_per_second;
- bucket.tokens = shape.capacity;
- bucket.last_refill = now;
- bucket.shape = shape;
+ // Carry the consumed fraction across the edit instead of granting
+ // a fresh full bucket on every shape change.
+ let filled = bucket.tokens / bucket.capacity.max(f64::MIN_POSITIVE);
+ bucket.capacity = shape.capacity;
+ bucket.refill_per_second = shape.refill_per_second;
+ bucket.tokens = (filled * shape.capacity).clamp(0.0, shape.capacity);
+ bucket.last_refill = now;
+ bucket.shape = shape;
}Add a test that charges the same key with two different configs in turn and asserts the counter still exhausts.
