⚡ Autonomous Linux Kernel, eBPF & XDP Programmable Dataplane Suite (2026)

A Production-Grade, Verifiable Synthetic Corpus for Training Autonomous Linux Kernel & eBPF Systems Agents

---

⚡ Overview & Industry Problem

Modern hyperscale cloud datacenters, bare-metal Kubernetes clusters, and low-latency financial trading nodes rely on in-kernel programmable dataplanes: eBPF, AF_XDP zero-copy rings, Traffic Control (TC) shapers, BPF LSM security hooks, and io_uring asynchronous IO. Standard LLMs catastrophically fail in kernel space: they emit unsafe pointers rejected by the BPF in-kernel verifier, trigger page faults in atomic interrupt contexts, cause false sharing across CPU cache lines, allocate heap memory on critical 100Gbps packet paths, and miss subtle RCU grace-period race conditions.

The Autonomous Linux Kernel, eBPF & XDP Programmable Dataplane Suite (2026) provides an uncompromising, industrial-grade foundation:

1. Verifiable Reward Signals (eval_assertion): 100% of rows include an executable, deterministically evaluatable unit-test assertion block for Reinforcement Learning from Verifiable Rewards (RLVR / GRPO / PPO).
2. Dense Production Implementations: Average code length of 100.95 LOC (strictly 80–150 LOC, zero toy snippets, zero placeholder stubs).
3. High-Contrast DPO Defense: Rejected implementations model subtle, catastrophic systems failures (e.g. non-preallocated BPF map lookups in atomic IRQ, verifier bounds clipping, torn lockless ring counters) contrasted against hardened kernel architectures.
