Technical Overview
Engineering breakdown of Hardening eBPF Kernel Socket Filters (8367). Bare-metal hardware performance requires isolated kernel parameters, strict verifier constraints, and zero-copy packet processing. This guide covers CVE-2024-8367 mitigation strategies, including JIT hardening, constant blinding, and speculative execution barriers. We explore the socket filter attachment lifecycle, BPF_PROG_TYPE_SOCKET_FILTER semantics, and the impact of BPF_MAP_TYPE_PERCPU_ARRAY on tail-call performance.
