Author: Grazvydas Ignotas <[email protected]> Date: Tue Aug 21 00:08:54 2018 +0300 radv: place pointer length into cache uuid Thanks to reproducible builds, binary file timestamps may be identical for both 32bit and 64bit packages when built from the same source. This means radv will use the same cache for both 32 and 64 bit processes, which leads to crashes. Conveniently there is a spare byte in cache_uuid, let's place the pointer size there.
