A Packet Journey — Tracing the Linux Kernel Networking Stack ♪ Listenable
We dissect the full path a packet takes from the NIC through DMA, ring buffers, NAPI, and the IP/TCP layers to the application socket. Covers RSS/RPS/RFS multi-core scaling, GRO/GSO/TSO offloads, XDP, socket buffer tunin

Injecting safe code into the kernel — that is the eBPF revolution. This post dissects eBPF from internals to practice: the VM and bytecode, the Verifier that enforces safety, maps (Hash/Array/Ring Buffer/Perf), program t

Everything about eBPF — from cBPF in 1992 to eBPF in 2014 to schedext in 2024. The 11-register virtual machine ISA, the verifier's static analysis, JIT compilation, BTF and CO-RE, 17+ BPF map types, 200+ helper functions
