ASR instrumentation is now performed on all applicable system services if the system is built with MKASR=yes. This setting automatically enables MKMAGIC=yes, which in turn enables MKBITCODE=yes. The number of extra rerandomized service binaries to be generated can be set by passing ASRCOUNT=n to the build system, where n is a number between 1 and 65536. The default ASRCOUNT is 3, meaning that each service will have one randomized base binary and three additional rerandomized binaries. As before, update_asr(8) can be used for runtime rerandomization.
