Month: 2025-08 Key feature delivered: Cross-architecture CFI type hashing support for BPF/JIT. Refactored BPF CFI types and helper routines from architecture-specific code into a generic module, reducing duplication and easing maintenance across architectures. This enables BPF JIT implementations to reliably use CFI type hashes for indirect calls. Major bugs fixed: None reported for geerlingguy/linux in this period. Overall impact and accomplishments: Improves cross-arch correctness and security posture by ensuring consistent CFI hashing; reduces maintenance burden and accelerates future architecture support. Lays groundwork for broader BPF/JIT improvements and cross-architecture portability. Technologies/skills demonstrated: C/C++ refactoring, BPF/JIT integration, architecture-agnostic design, cross-architecture code organization, traceable commits.
