ieee802154: ca8210: Add missing check for kfifo_alloc() in ca8210_probe()

2025-01-17T12:36:11+00:00

[ Upstream commit 2c87309ea741341c6722efdf1fb3f50dd427c823 ] ca8210_test_interface_init() returns the result of kfifo_alloc(), which can be non-zero in case of an error. The caller, ca8210_probe(), should check the return value and do error-handling if it fails.

net: ieee802154: adf7242: Fix some potential buffer overflow in adf7242_stats_show()

2023-10-22T10:28:43+00:00

strncat() usage in adf7242_debugfs_init() is wrong. The size given to strncat() is the maximum number of bytes that can be written, excluding the trailing NULL. Here, the size that is passed, DNAME_INLINE_LEN, does not take into account the size of "adf7242-" that is already in the array. In order to fix it, use snprintf() instead.

ieee802154: ca8210: Fix a potential UAF in ca8210_probe

2023-10-07T18:37:38+00:00

If of_clk_add_provider() fails in ca8210_register_ext_clock(), it calls clk_unregister() to release priv->clk and returns an error. However, the caller ca8210_probe() then calls ca8210_remove(), where priv->clk is freed again in ca8210_unregister_ext_clock(). In this case, a use-after-free may happen in the second time we call clk_unregister(). Fix this by removing the first clk_unregister(). Also, priv->clk could be an error code on failure of clk_register_fixed_rate(). Use IS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().

net: Explicitly include correct DT includes

2023-07-28T03:33:16+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
