Jul 1, 2026July 2026 monthly summary for oxidecomputer/hubris focusing on performance-review-relevant outcomes. Delivered a critical Root of Trust (RoT) attestation bug fix and a robustness improvement in the nonce_size validation path. Implemented validation to verify nonce_size against the actual blob length during attest requests, preventing potential RoT panics. The fix returns BadMessageLength for invalid sizes and includes updates to error documentation. The change preserves existing error variants to minimize risk and maintains MGS compatibility. Behavior validated in grapefruit-based testing to ensure reliability in edge cases and under test harness conditions.

Jun 1, 2026Month: 2026-06 — Focused delivery of hardware monitoring features for PSU health telemetry and configuration management to support Brussels SP releases. Key features delivered: - PMBus-based monitoring for MWOCP67 PSUs with temperature polling: Implemented PMBus communication with MWOCP67 PSUs, consolidated the PSC-seq-server and observer-seq-server into a single configurable task, and added onboard tmp117 temperature polling. Dev builds now include a framulator to validate FRAM interactions. End-to-end telemetry (model, serial, temps, fan, status_word) is surfaced in dashboards for proactive health checks. Validation covered basic PMBus reads and thermal/fan data; PSU insert/remove events are propagated to the ringbuf as expected. Note: some hardware-page- and temp sensor anomalies observed in early validation; follow-up required for rack-level rail enumeration and EEPROM model specifics. - Brussels SP release process enhancement: include observer-a in Brussels configuration: Updated Brussels release configuration to ensure observer-a participates in SP releases, reducing manual steps and improving release reliability. Major bugs fixed: - No major user-facing bugs fixed in this period. Effort was concentrated on feature delivery, integration, and configuration management with emphasis on test coverage and observability. Overall impact and accomplishments: - Significantly improved PSU observability and health telemetry for MWOCP67, enabling faster MTTR and better capacity planning. - Streamlined Brussels SP release process by guaranteeing observer-a inclusion, enhancing release consistency and reliability across environments. - Demonstrated end-to-end hardware/software integration, including PMBus interactions, EEPROM reads, and sensor data validation; the work lays groundwork for further firmware-page and power-rail enumeration refinements. Technologies/skills demonstrated: - PMBus protocol and hardware telemetry (model/ID/serial, temps, rail data, fan speed, status_word). - Server consolidation and config-driven workflows to simplify maintenance. - Embedded sensor data handling (tmp117), FRAM testing (framulator), and EEPROM access (AT24CSW080 VPD, M24C02). - Release configuration management for Brussels SP processes.
