Christophe, I think we are in agreement. If I understand correctly, it should not be possible to enable CONFIG_STRICT_MODULE_RWX without CONFIG_ARCH_HAS_STRICT_MODULE_RWX (or inversely), as per arch/Kconfig: config STRICT_MODULE_RWX bool "Set loadable kernel module data as NX and text as RO" if ARCH_OPTIONAL_KERNEL_RWX depends on ARCH_HAS_STRICT_MODULE_RWX && MODULES default !ARCH_OPTIONAL_KERNEL_RWX || ARCH_OPTIONAL_KERNEL_RWX_DEFAULT The objective of Linus' commit ad21fc4faa2a1 ("arch: Move CONFIG_DEBUG_RODATA and CONFIG_SET_MODULE_RONX to be common") and in particular commit 0f5bf6d0afe4b ("arch: Rename CONFIG_DEBUG_RODATA and CONFIG_DEBUG_MODULE_RONX") does seem correct. So, architectures that would prefer to make this feature selectable rather than enabled by default should continue to have this option. > module_enable_x() should work just fine regardless of > CONFIG_ARCH_HAS_STRICT_MODULE_RWX. As per the above, we should fix commit 93651f80dcb6 ("modules: fix compile error if don't have strict module rwx") so a stub for module_enable_x() would no longer be required, right?
