Linux Kernel eBPF sk_lookup: Multi-Tenant Socket Routing & Zero-Port Load Balancing

An advanced Linux network systems guide to BPF socket lookup (sk_lookup). We analyze programmatic L4 socket redirection, eliminating port-range limits for multi-tenant services, and zero-copy in-kernel load balancing at 10M packets/sec.
