What

Adds nodemaven as a proxy provider, next to custom and dataimpulse. Set PROXY_PROVIDER=nodemaven and use the usual PROXY_URL.

NodeMaven puts country and session into the username (login-country-us-sid-abc), so the provider:

• reads the country for geoip-match
• swaps it for geo routing (region, city and ISP are dropped with the old country, kept otherwise)
• adds or replaces -sid- for sticky sessions

It's registered in registry.py, and .env.example has an example URL.

Why

Same idea as the DataImpulse provider, just a different username format. Through custom the proxy works, but geo routing and sticky sessions don't.

Fixes

No issue for this one.

How to test

cd surfsense_backend && uv run pytest -m unit tests/unit/utils/proxy/

test_nodemaven_provider.py mirrors the DataImpulse tests, plus one registry case. I couldn't install the full backend locally, so I ran these with app.config stubbed out. CI should cover the real run.

High-level PR Summary

This PR adds a new proxy provider called NodeMaven to support NodeMaven's residential/rotating proxy service. The implementation follows the same pattern as the existing DataImpulse provider but adapts to NodeMaven's unique username syntax (login-country-us-sid-abc) for handling country-based routing and sticky sessions. The provider parses country codes from the username for geo-matching, rewrites usernames for geo-routing (dropping region/city/ISP when country changes), and manages session IDs for sticky connections. Server-side rotation means no client-side pool management is needed.

📝 Walkthrough

Walkthrough

This change adds a NodeMaven proxy provider with country and sticky-session URL handling. It registers the provider for selection through PROXY_PROVIDER and adds configuration examples and unit tests.

Changes

NodeMaven proxy support

Layer / File(s)	Summary
NodeMaven URL handling surfsense_backend/app/utils/proxy/providers/nodemaven.py, surfsense_backend/tests/unit/utils/proxy/test_nodemaven_provider.py	NodeMavenProvider reads the configured proxy URL, extracts country information, and rewrites country and session parameters. Tests cover URL handling, validation, and Playwright proxy conversion.
Provider selection and configuration surfsense_backend/app/utils/proxy/registry.py, surfsense_backend/.env.example, surfsense_backend/tests/unit/utils/proxy/test_registry.py	The registry supports selecting NodeMavenProvider through PROXY_PROVIDER. The environment example documents the provider and a country parameter. The registry test verifies provider selection.

Change: Feature

Merge Risk: 🔵 Low · up to a6712

The NodeMaven provider is additive and opt-in. A credential-less proxy URL could produce a malformed rewritten URL, which is unlikely because NodeMaven requires credentials. This is mergeable with a small follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to a6712

NodeMaven fits the existing proxy interface without changing the default provider. Country and session inputs are constrained to routing parameters, while the proxy endpoint and credentials remain configuration-owned. No introduced security concern was established, but production configuration ownership and vendor behavior were not validated.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The effective scope is backend traffic using the process-wide selected proxy provider, rather than a new tenant-specific authority. Selecting NodeMaven changes routing semantics for those consumers, but does not give country or session callers control over the configured proxy destination or credentials.

Trust Boundaries and Controls

• observed — The examined request-controlled country path reaches a credential-bearing proxy URL only through constrained username routing parameters. Provider selection and the canonical endpoint remain process configuration. The existing explicit proxy override is unchanged and is not evidence that NodeMaven introduced a new destination-control path.

Resilience and Maintainability Implications

• observed — Sticky-session construction computes a URL from configuration on each call without allocating or persisting a local session. Missing configuration returns None; an unusable session identifier raises before a URL is returned. Repetition, interruption, or concurrent construction does not leave a partially updated local session or require cleanup. Upstream session lifecycle remains outside the inspected implementation.

80-84: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

Low-risk edge: a URL without credentials produces a malformed netloc.

If PROXY_URL has no userinfo, userinfo is "". The code still appends @, so the result starts with @host. NodeMaven always needs credentials, so this is unlikely. Build the @ only when userinfo is non-empty.
