# After migration the security feature flags might have changed (e.g., # destination system with unpatched firmware), but some flags are not # set/clear again in init_cpu_char_feature_flags() because it assumes # the security flags to be the defaults. # # Additionally, if the H_GET_CPU_CHARACTERISTICS hypercall fails then # init_cpu_char_feature_flags() does not run again, which potentially # might leave the system in an insecure or sub-optimal configuration. # # So, just restore the security feature flags to the defaults assumed # by init_cpu_char_feature_flags() so it can set/clear them correctly, # and to ensure safe settings are in place in case the hypercall fail. #
