Patch series "kasan: migrate the last module test to kunit", v4.
copy_user_test() is the last KUnit-incompatible test with
CONFIG_KASAN_MODULE_TEST requirement, which we are going to migrate to
KUnit framework and delete the former test and Kconfig as well.
In this patch series:
- [1/3] move kasan_check_write() and check_object_size() to
do_strncpy_from_user() to cover with KASAN checks with
multiple conditions in strncpy_from_user().
- [2/3] migrated copy_user_test() to KUnit, where we can also test
strncpy_from_user() due to [1/4].
KUnits have been tested on:
- x86_64 with CONFIG_KASAN_GENERIC. Passed
- arm64 with CONFIG_KASAN_SW_TAGS. 1 fail. See [1]
- arm64 with CONFIG_KASAN_HW_TAGS. 1 fail. See [1]
[1] https://lore.kernel.org/linux-mm/CACzwLxj21h7nCcS2-KA_q7ybe+5pxH0uCDwu64q_9pPsydneWQ@mail.gmail.com/
- [3/3] delete CONFIG_KASAN_MODULE_TEST and documentation occurrences.
This patch (of 3):
Since in the commit 2865baf54077("x86: support user address masking
instead of non-speculative conditional") do_strncpy_from_user() is called
from multiple places, we should sanitize the kernel *dst memory and size
which were done in strncpy_from_user() previously.

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.
