`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We know `fw_type` must be NUL-terminated based on use here: | static bool fw_type_is_auto(void) | { | return strncmp(fw_type, LIO_FW_NAME_TYPE_AUTO, | sizeof(LIO_FW_NAME_TYPE_AUTO)) == 0; | } ...and here | module_param_string(fw_type, fw_type, sizeof(fw_type), 0444); Let's opt to NUL-pad the destination buffer as well so that we maintain the same exact behavior that `strncpy` provided here. A suitable replacement is `strscpy_pad` due to the fact that it guarantees both NUL-termination and NUL-padding on the destination buffer.

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.
