Jan 1, 2025January 2025 monthly summary for intel/intel-ipsec-mb focusing on business value and technical achievements. Key feature/bug fix delivered: corrected CBC mode block alignment in the DOCSIS implementation within the AVX2_T2 library to ensure 16-byte block boundaries, preventing data processing errors. This fix was implemented in the avx2_t2 path and committed as 308c2d8307d5b59b3419ea2bd295bd3c18fe0eb7 (avx2_t2: fix DOCSIS implementation). Impact includes improved data integrity and reliability of the DOCSIS cryptographic path, reduced risk of misalignment-related failures in IPsec processing, and more predictable throughput for secure VPN/DOCSIS workloads. Technologies/skills demonstrated: low-level data alignment, AVX2 vectorization, C/C++, cryptographic implementation, debugging and code review. Future work: monitoring for any edge case in DOCSIS traffic and validating across diverse hardware.

Dec 1, 2024Month: 2024-12 — Summary: Delivered a major SIMD refactor for ZUC in intel/intel-ipsec-mb, replacing repetitive preprocessor macros with explicit loops across AVX-512, AVX2, and SSE. Consolidated ZUC initialization, key generation, and keystream/encryption loops, with new load/store macros for LFSR registers. This refactor improves code clarity, portability, and potential performance across backends, reduces macro-related maintenance risk, and sets groundwork for further architecture-specific optimizations. Commits touched Init, Cipher, and Keygen paths across avx512_t1, avx2_t1, and sse_t1 backends, enhancing consistency and correctness across SIMD targets.

Oct 1, 2024October 2024 monthly summary for intel/intel-ipsec-mb. Focused on API clarity, backward compatibility, and ecosystem readiness. Delivered key improvements that reduce ambiguity, streamline maintenance, and position the project for SPDK ecosystem adoption. Major work areas included cipher mode naming standardization, Wireless API modernization, and Version 2.0 release with comprehensive documentation. Key outcomes: - Cipher mode naming standardization: SM4-CNTR references renamed to SM4-CTR with CTR aliases, preserving legacy IMB_CIPHER_SM4_CNTR for API compatibility. This reduces confusion and improves maintainability across the API surface.
