[PATCH] powerpc/config: Enable secuity features in skiroot

2020-01-01 Thread Joel Stanley
This turns on HARDENED_USERCOPY with HARDENED_USERCOPY_PAGESPAN, and FORTIFY_SOURCE. It also enables SECURITY_LOCKDOWN_LSM with _EARLY and LOCK_DOWN_KERNEL_FORCE_CONFIDENTIALITY options enabled. MODULE_SIG is selected by lockdown, so it is still enabled. Signed-off-by: Joel Stanley ---
