I am bomberrie. I engineer Linux kernel flow-offload mitigations, line-rate zero-copy eBPF/XDP telemetry probes, and fault-tolerant distributed infrastructure.

#CORE OBJECTIVES:

├─ Eliminating conntrack / flowtable MAC corruption on multi-WAN PBR

├─ Sub-microsecond driver-layer packet telemetry via Aya / eBPF ring buffers

└─ Declarative, deterministic bare-metal matrix orchestrated with NixOS Flakes

PRODUCTION_PATCH

KERNEL BUG AUDIT & REPRODUCER

openwrt-flowoffload-pbr-mac-misroute

> ./inspect_repo.sh --branch main

Root-cause diagnosis, synthetic netns reproducer, and kernel patch resolving MAC header corruption in OpenWrt 24.10 when software/hardware flowtables bypass Policy-Based Routing (PBR) neighbor lookups.

[+] Identified flowtable egress shortcut bypassing rt6_info/rt4 neighbor resolution

[+] Isolated multi-WAN gateway packet corruption causing asymmetric blackholes

[+] Engineered nftables workaround & upstream kernel skb->dev egress verification suite

IMPACT: 100% resolution of corrupted L2 frames on multi-WAN routing gateways

DRIVER-LEVEL PACKET ANALYZER

ebpf-xdp-telemetry-engine

> ./inspect_repo.sh --branch main

High-frequency packet parser and zero-copy metric extractor operating directly at the NIC driver layer via eBPF/XDP, streaming L4-L7 flow states through lock-free ring buffers.

[+] Executes in XDP_DRV mode before kernel sk_buff allocation for line-rate parsing

[+] Memory-mapped BPF perf/ring buffers streaming metrics directly into Rust userspace

[+] Real-time TCP window anomaly & out-of-order packet reassembly detection

IMPACT: 14.88 Mpps sustained line-rate packet inspection with < 0.8% CPU load

> ./inspect_repo.sh --branch main

Autonomous peer-to-peer overlay network daemon featuring zero-trust dynamic routing, automated NAT traversal via STUN/DERP, and latency-optimized path switching.

[+] Direct kernel Netlink wireguard interface manipulation without userspace packet copy

[+] Continuous asynchronous UDP RTT latency probing matrix across all nodes

[+] Automated elliptic-curve ephemeral key rotation every 120 seconds

IMPACT: Sub-240ms automated link failover with zero manual tunnel reconfiguration

LOW-LATENCY PERSISTENCE ENGINE

hyper-lsm-kv-engine

> ./inspect_repo.sh --branch main

Log-Structured Merge-tree storage engine implementing lock-free memtable concurrency, asynchronous io_uring disk flushes, and SIMD-accelerated Bloom filters.

[+] Lock-free skiplist memtable supporting concurrent writes via atomic CAS operations

[+] Asynchronous page-cache bypass write-ahead log (WAL) utilizing Linux io_uring

[+] Multi-level compaction daemon with zero-copy block decompression

IMPACT: > 480k IOPS write throughput on direct NVMe storage
