Subject: [PATCH v2 09/10] common: add generic CONFIG_KASAN option
Date: Tue, 27 Aug 2019 17:09:17 +0200 [thread overview]
Message-ID: <20190827150918.16247-10-ahmad@a3f.at> (raw)
In-Reply-To: <20190827150918.16247-1-ahmad@a3f.at>
-fsanitize=[kernel-]address-sanitizer allows compile-time instrumentation
of memory accesses to detect some classes of runtime undefined behavior.
In preparation for allowing arches to provide infrastructure in support
of this feature, add the generic KASAN options.
These are only shown in the debug menu when the arch selects the
appropriate symbol. The option is named equally to their Linux counterparts.
