Subject: [PATCH v2 0/3] Allow CONFIG_DEBUG_SET_MODULE_RONX to be used on ARM
Date: Mon, 17 Jun 2013 10:29:11 -0700	[thread overview]
Message-ID: <1371490154-11041-1-git-send-email-lauraa@codeaurora.org> (raw)

Hi,

This is a series to allow CONFIG_DEBUG_SET_MODULE_RONX to be used on ARM. The
current config description from x86 describes it best:

	This option helps catch unintended modifications to loadable
	kernel module's text and read-only data. It also prevents execution
	of module data. Such protection may interfere with run-time code
	patching and dynamic kernel tracing - and they might also protect
	against certain classes of kernel exploits.

v2: Add module bounds checking per Russell, removed dsb per Catalin.
Macrofied the set_memory_* functions to avoid so much code duplication.

Thanks,
Laura
