Visa Hankala 6daa52884c xfrm: Fix wraparound in xfrm_policy_addr_delta() ... [ Upstream commit da64ae2d35d3673233f0403b035d4c6acbf71965 ] Use three-way comparison for address components to avoid integer wraparound in the result of xfrm_policy_addr_delta(). This ensures that the search trees are built and traversed correctly. Treat IPv4 and IPv6 similarly by returning 0 when prefixlen == 0. Prefix /0 has only one equivalence class.
