Could you build this?
No Developing deep packet inspection bypass mechanisms using Linux kernel eBPF sock_ops requires specialized low-level networking, Linux kernel internals, and TCP/IP stack manipulation skills.
What it would actually take: The system requires writing C eBPF programs attached to sock_ops/sk_msg kernel hooks (using libbpf/Cilium) to intercept TCP handshakes and manipulate TCP window sizes, segmentation, or TLS Client Hello packets in-flight. The core difficulty lies in avoiding kernel panics, adhering strictly to the eBPF verifier's safety constraints, and correctly simulating TCP packet fragmentation to evade DPI middleboxes. This requires deep expertise in Linux kernel programming, network protocol security, and eBPF tooling.

Concerns raised: More sophisticated DPI systems like China's GFW can do full TCP reassembly, Doesn't work against stateful/reassembly-capable DPI
