+ bool "Undefined behaviour sanity checker"
+ help
+ This option enables undefined behaviour sanity checker
+ Compile-time instrumentation is used to detect various undefined
+ behaviours in runtime. Various types of checks may be enabled

+ help
+ This option activates instrumentation for the entire kernel.
+ If you don't enable this option, you have to explicitly specify
+ UBSAN_SANITIZE := y for the files/directories you want to check for UB.
+ Enabling this option will get kernel image size increased
+ significantly.

+config UBSAN_ALIGNMENT
+ bool "Enable checking of pointers alignment"

+ default y if !HAVE_EFFICIENT_UNALIGNED_ACCESS
+ help
+ This option enables detection of unaligned memory accesses.
+ Enabling this option on architectures that support unaligned
+ accesses may produce a lot of false positives.
+
+config UBSAN_NULL
+ bool "Enable checking of null pointers"
+ depends on UBSAN
+ default y if !ARCH_WANTS_UBSAN_NO_NULL
+ help
+ This option enables detection of memory accesses via a
+ null pointer.
