May 1, 2026Month: 2026-05 — Delivered key features and bug fixes for lf-edge/eve with a strong focus on reliability, security, and deployment stability. Key features include SCEP certificate management improvements with a CSR attribute-ordering fix to support certain SCEP servers and an added validation test, plus cleanup of obsolete enrolled certificates to prevent orphaned files. Network reliability enhancements cover forced re-parsing of bonds/VLANs when lower-layer changes occur, and activation of ARP validation on bonds to reduce cross-node interference. DHCP-related robustness improvements include preserving DHCP reacquires during concurrent DPC updates and a dnsmasq lease-cleanup workflow on app deletion to evict stale leases. A virtctl compatibility update aligns VIRTCTL with KubeVirt v1.7.3 to resolve deployment issues. Overall impact: higher enrollment success rates, more stable networking in clustered environments, and smoother, faster deployments. Technologies/skills demonstrated include x509 CSR handling and direct CSR DER manipulation, network bonding/ARP tuning, DHCP/DNSMasq coordination, and Kubernetes client compatibility."
