Chain two XDP programs via libxdp dispatcher on the same interface: xdp_blocker (priority 10) handles CIDR/country/whitelist blocking, xdp_ddos (priority 20) handles rate limiting, EWMA analysis, and AI anomaly detection. Whitelist maps are shared via BPF map pinning so whitelisted IPs bypass both blocklist checks and DDoS rate limiting. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
