[ Upstream commit 2810c1e99867a811e631dd24e63e6c1e3b78a59d ]
Inject fault while probing kunit-example-test.ko, if kstrdup()
fails in mod_sysfs_setup() in load_module(), the mod->state will
switch from MODULE_STATE_COMING to MODULE_STATE_GOING instead of
from MODULE_STATE_LIVE to MODULE_STATE_GOING, so only
kunit_module_exit() will be called without kunit_module_init(), and
the mod->kunit_suites is no set correctly and the free in
kunit_free_suite_set() will cause below wild-memory-access bug.
The mod->state state machine when load_module() succeeds:
MODULE_STATE_UNFORMED ---> MODULE_STATE_COMING ---> MODULE_STATE_LIVE
^ |
| | delete_module
+---------------- MODULE_STATE_GOING <---------+
The mod->state state machine when load_module() fails at
mod_sysfs_setup():
MODULE_STATE_UNFORMED ---> MODULE_STATE_COMING ---> MODULE_STATE_GOING
^ |
| |
+-----------------------------------------------+
Call kunit_module_init() at MODULE_STATE_COMING state to fix the issue
because MODULE_STATE_LIVE is transformed from it.

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 Restructured Text 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.
