May 2026 overall results for githedgehog/dataplane: delivered a set of targeted reliability and capability improvements across configuration handling, API surface, and data plane logic. The work emphasizes automation efficiency, robust validation, and scalable config processing, with substantial test coverage upgrades.

Month: 2026-04 — Dataplane development: delivered selected features, hardened NAT/error handling, and introduced a validated configuration surface to improve safety, testability, and deployment velocity across the data plane. Key features delivered include VpcManifest::with_exposes() to simplify test setup and pave the way for a new field, and PrefixPortsSet::total_prefixes_size() to enable accurate capacity sizing in production planning. Major fixes and quality work include expanded NAT error handling with new AllocatorError, IcmpErrorMsgError, and StatelessNatError variants, plus NAT test cleanup and organization to stabilize CI and test coverage. Architectural and config improvements include introducing a family of Validated* wrappers (ValidatedExpose, ValidatedManifest, ValidatedPeering, ValidatedVpc, ValidatedVpcTable, ValidatedOverlay, ValidatedExternalConfig, ValidatedGwConfig) and migrating consumers to validated types to centralize invariants and reduce raw access. Additional work across tooling and CI hygiene includes dependency bumps, FRR pin adjustments, a cargo alias for tests, and documentation note on Flatpak permissions.

March 2026 (2026-03) dataplane monthly summary for githedgehog/dataplane. Focused on delivering robust NAT/flow-filter capabilities, improving test infrastructure, and updating build tooling to support new NAT modes and smoother CI. Key notes: Port forwarding validation now supports TCP/UDP with improved overlap handling; Flow-filter underwent a major refactor introducing a named table and subtables, separating prefix splitting from map updates, and introducing PrefixPortsSet for cleaner API; ICMP handling gained a dedicated flow-filter sub-table to ensure correct matching for non-L4-port traffic; NAT translation core received meaningful refinements (NatFlowState enum, reduced allocations for reverse flows) and NAT display improvements; Build tooling and workspace were updated (version bump tooling, lpm crate, and CI workflows) to streamline releases and licensing compliance. This combination increases reliability in cross-VPC connectivity, improves performance via leaner NAT/flow-filter data paths, expands test coverage for edge cases (ICMP and port-less traffic), and accelerates release cycles with automated versioning and CI improvements.
