To build with KASAN enabled, add the --kasan
flag. Example:
$ tools/bazel build --kasan //common:kernel_aarch64
Kasan builds automatically disable LTO by setting its value to none
. If --lto
is explicitly specified, it must be set to none
. Otherwise the build fails.
--config=fast
--config=fast
specifies --lto=thin
, which is not allowed by --kasan
. If you want to disable some sandboxes to make incremental build faster, use --config=local
instead. For example:
$ tools/bazel build --kasan --config=local //common:kernel_aarch64
--kasan
You may build the following to confirm the value of kasan setting:
$ tools/bazel build [flags] //build/kernel/kleaf:print_flags
Note: the value of --lto
reflects the value specified on the command line, which may show default
or none
. However, if --kasan
is specified, --lto
is coerced into none
, no matter if it is specified on the command line.
