This series addresses build failures and warnings that occur when compiling DPDK with Link Time Optimization (LTO) enabled. LTO performs aggressive cross-compilation-unit inlining, which allows GCC's static analyzer to detect both real bugs and generate false positive warnings that are not visible without LTO.
The series fixes: - Real bugs: buffer overflow in cnxk reassembly SA setup (heap corruption) - Variable-length arrays that trigger warnings with LTO - False positive warnings where compiler cannot prove bounds safety v4 - add Fixes tags where appropriate - Bugzilla ID's for existing bugs The cnxk patches (1-4) should be applied together as they eliminate all VLAs from common/cnxk and re-enable VLA warnings. The remaining patches (5-6) address warnings in other subsystems.
