I will walk you through a working eBPF IDS Linux setup that hooks kernel events, streams signals to user space, and keeps performance predictable. I start from how the verifier and JIT work in the linux kernel so you can pick the right attach points. I explain kprobes, tracepoints, uprobes, XDP, and LSM in plain […]
The eBPF port scanning detection approach shows how kernel-level programs can answer TCP SYNs without leaving the fast path. I guide you through a compact XDP example that reads Ethernet, IPv4, and TCP headers in the kernel. You will see how a simple program spots a SYN and replies with a SYN-ACK to emulate an […]
Most probe shell failures come from a mismatched process, account, or environment. Trace execve, logs, paths, and integration to isolate the real cause.
You feel the pressure when network flows stall, and packet drop monitoring eBPF is the fastest way to surface the kernel’s reason for loss so you can act with confidence. We outline a practical path—attach an ebpf program to a tracepoint, capture events at the linux kernel, and export clear flow-level data to dashboards. This […]
Stop looking for CONFIG_HAVE_EBPF_JIT in menuconfig. Stop looking for CONFIG HAVE EBPF JIT in menuconfig. It describes a marker, not a feature you switch on.
Pixie uses eBPF to expose Kubernetes HTTP, gRPC, TLS, database, and network telemetry without code changes, while showing where kernel-level visibility ends.
Windows eBPF is production-ready for network filtering and observability, but runs through its own verifier and hooks – not recompiled Linux bytecode.
Cilium eBPF use cases include identity-based policy, service load balancing, and flow visibility, with clear limits for custom tooling and basic networking.
