From: Zeng Heng <zengheng4(a)huawei.com>
mainline inclusion
from mainline-v6.1
commit ec851b23084b3a0af8bf0f5e51d33a8d678bdc49
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRIL
CVE: CVE-2022-48975
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
Here is a backtrace report about memory leak detected in
gpiochip_setup_dev():
unreferenced object 0xffff88810b406400 (size 512):
comm "python3", pid 1682, jiffies 4295346908 (age 24.090s)
backtrace:
kmalloc_trace
device_add device_private_init at drivers/base/core.c:3361
(inlined by) device_add at drivers/base/core.c:3411
cdev_device_add
gpiolib_cdev_register
gpiochip_setup_dev
gpiochip_add_data_with_key
gcdev_register() & gcdev_unregister() would call device_add() &
device_del() (no matter CONFIG_GPIO_CDEV is enabled or not) to
register/unregister device.
However, if device_add() succeeds, some resource (like
struct device_private allocated by device_private_init())
is not released by device_del().
Therefore, after device_add() succeeds by gcdev_register(), it
needs to call put_device() to release resource in the error handle
path.
Here we move forward the register of release function, and let it
release every piece of resource by put_device() instead of kfree().
While at it, fix another subtle issue, i.e. when gc->ngpio is equal
to 0, we still call kcalloc() and, in case of further error, kfree()
on the ZERO_PTR pointer, which is not NULL. It's not a bug per se,
but rather waste of the resources and potentially wrong expectation
about contents of the gdev->descs variable.
