Worked on the psleng/vyos-1x repository to deliver authentication, network interface management, and configuration enhancements over four months. Developed and migrated authentication flows from SAML to login-based systems, strengthened API security, and improved SSO persistence using Python and XML. Implemented deterministic Ethernet interface naming with udev rules and Python scripting, ensuring reliable hardware identification and board-agnostic deployments. Addressed schema compliance, error handling, and configuration usability, while resolving critical bugs affecting production stability. The work emphasized maintainability and operational readiness, reducing onboarding friction and supporting scalable automation for network devices through robust backend development and system administration practices.

May 1, 2026Implemented a comprehensive deterministic Ethernet interface naming and management layer for psleng/vyos-1x. Key changes include new udev rules, .link definitions, and supporting scripts to name interfaces by port numbers and hardware identifiers, with robust handling for pinned interfaces and hardware IDs across multiple hardware revisions. The work also involved extensive fixes and refinements to hw-id mapping, enumeration order stability, and boot-time behavior to improve reliability across deployments. Major updates and fixes were delivered across a single feature-focused effort, including: - Deterministic naming delivered through updated udev rules, .link files, and associated scripts, enabling port-number-based naming and stable hardware-ID handling. (Commits addressing hard link/files, portable guards, DT port MAC walk, and hw-id mapping.) - Hardened hardware-id mapping and pinned-interface handling: added hw-id skip path for pinned interfaces and improved mapping when link files are correctly selected, reducing mislabeling and boot-time warnings. - Stabilized enumeration and event handling: fixes for incorrect enumeration ordering and rare change events to ensure predictable naming across hardware revisions. - Boot/initramfs and squashfs compatibility: fixes to squashfs udev rule interactions and initramfs-related issues to ensure rules apply reliably during early boot. - DT port identification fallback: implemented MAC-based port identification for DT ports when cpsw driver does not expose port information, improving cross-hardware compatibility. Overall impact: improved network provisioning reliability, reduced post-boot misconfigurations, and a clearer automation surface for lifecycle management. Demonstrates proficiency with Linux udev, .link, and hardware-id mapping, plus cross-hardware portability and boot-time reliability. Business value: predictable network interfaces simplify automation, reduce troubleshooting time, and accelerate scalable deployments across the fleet.
