1 config ARCH_HAS_UBSAN_SANITIZE_ALL
5 bool "Undefined behaviour sanity checker"
7 This option enables undefined behaviour sanity checker
8 Compile-time instrumentation is used to detect various undefined
9 behaviours in runtime. Various types of checks may be enabled
10 via boot parameter ubsan_handle (see: Documentation/ubsan.txt).
12 config UBSAN_SANITIZE_ALL
13 bool "Enable instrumentation for the entire kernel"
15 depends on ARCH_HAS_UBSAN_SANITIZE_ALL
18 This option activates instrumentation for the entire kernel.
19 If you don't enable this option, you have to explicitly specify
20 UBSAN_SANITIZE := y for the files/directories you want to check for UB.
21 Enabling this option will get kernel image size increased
24 config UBSAN_ALIGNMENT
25 bool "Enable checking of pointers alignment"
27 default y if !HAVE_EFFICIENT_UNALIGNED_ACCESS
29 This option enables detection of unaligned memory accesses.
30 Enabling this option on architectures that support unaligned
31 accesses may produce a lot of false positives.
