The initial change that added kernel/configs/hardening.config attempted
to disable all UBSAN sanitizers except for the array bounds one while
turning on UBSAN_TRAP. Unfortunately, it only got the syntax for
CONFIG_UBSAN_SHIFT correct, so configurations that are on by default
with CONFIG_UBSAN=y such as CONFIG_UBSAN_{BOOL,ENUM} do not get disabled
properly.
CONFIG_ARCH_HAS_UBSAN=y
CONFIG_UBSAN=y
CONFIG_UBSAN_TRAP=y
CONFIG_CC_HAS_UBSAN_BOUNDS_STRICT=y
CONFIG_UBSAN_BOUNDS=y
CONFIG_UBSAN_BOUNDS_STRICT=y
# CONFIG_UBSAN_SHIFT is not set
# CONFIG_UBSAN_DIV_ZERO is not set
# CONFIG_UBSAN_UNREACHABLE is not set
CONFIG_UBSAN_SIGNED_WRAP=y
CONFIG_UBSAN_BOOL=y
CONFIG_UBSAN_ENUM=y
# CONFIG_TEST_UBSAN is not set
Add the missing 'is not set' to each configuration that needs it so that
they get disabled as intended.
CONFIG_ARCH_HAS_UBSAN=y
CONFIG_UBSAN=y

CONFIG_CC_HAS_UBSAN_BOUNDS_STRICT=y

# CONFIG_UBSAN_SHIFT is not set

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
