TLDR; fixes LTO build Full explaination from AI... This patch series addresses multiple compilation warnings and one buffer overflow bug that are revealed when with Link Time Optimization (LTO) enabled.
LTO enables cross-compilation-unit analysis and inlining, which allows GCC to detect issues that would otherwise be hidden. The patches fall into three categories: 1. Variable Length Array (VLA) fixes in common/cnxk [patches 1-3] - Replace VLAs with fixed-size arrays and appropriate bounds checking - Re-enable VLA warnings after fixes are complete 2. Actual bug fix in common/cnxk [patch 4] - Fixes buffer overflow in IPsec inbound SA initialization - Detected by GCC's -Wstringop-overflow with LTO enabled 3. False positive warning fixes [patches 5-6] - Add explicit bounds checks to help GCC's static analysis - Adjust inline attributes to prevent spurious warnings All patches have been tested with LTO enabled and resolve the respective compilation warnings.
