How a Nix community effort led to a Linux kernel patch adding programmable $ORIGIN support via eBPF and binfmt_misc, without breaking process identity.
DOOM runs inside the Linux kernel via unmodified eBPF
BPF Capsule compiles DOOM and other complex C/C++/Rust programs into standard eBPF, running them unmodified through the stock Linux verifier and JIT.
Netflix Explains Service Topology: A Real-Time Map for Thousands of Microservices
Netflix details Service Topology, a real-time dependency map spanning thousands of microservices. Learn how eBPF, application-layer, and trace data combine for fast incident response.

commitbrief.comProof-Carrying-BPF Programs Aim to Expand eBPF Verifier Acceptance
A SOSP '26 paper proposes proof-carrying-BPF programs, letting the eBPF verifier accept complex programs it previously rejected via formal proofs.
64 BFD sessions at 10ms saturate FRR bfdd's core; XDP handles it at 0 flaps
FRR's bfdd saturates one core at 64 BFD sessions while an XDP fast path carries the same load at 751ns/packet with zero flaps; three FRR bugs merged upstream.
Cloudflare's eBPF Series Part 2: Closing Gaps in Linux Networking APIs
Cloudflare's eBPF series part 2 details L4Drop, xdpcap, Tubular, and cbpfc — the tools built to overcome Linux networking API limits at scale.
Furtex: Linux Post-Exploitation and Evasion Research Toolkit
Furtex is a Linux post-exploitation and evasion research toolkit based on io_uring and eBPF, designed for authorized research.
XDP BFD Integrates with Stock FRR, Eliminates Flaps Under Stress
XDP-based BFD now integrates with stock FRR bfdd, cutting flaps to zero under stress and uncovering upstream FRR and kernel bugs along the way.
bfdd vs XDP-based BFD Fast Path Under CPU Stress: 44 vs 0 Flaps
Under CPU stress, FRR's bfdd flapped 44 times in 120 seconds while an XDP-based BFD fast path stayed at zero flaps, matching line-card-level reliability.
Sip-exporter: eBPF-Based SIP/RTP Monitoring for Prometheus
Sip-exporter uses eBPF to capture SIP/RTP traffic in-kernel and export voice quality, fraud detection, and RFC 6076 metrics to Prometheus.
