Erick Archer c727e46f0c Input: ff-core - prefer struct_size over open coded arithmetic ... [ Upstream commit a08b8f8557 ] This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1][2]. As the "ff" variable is a pointer to "struct ff_device" and this structure ends in a flexible array: struct ff_device { [...] struct file *effect_owners[] __counted_by(max_effects); }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the calculation "size + count * size" in the kzalloc() function. The struct_size() helper returns SIZE_MAX on overflow. So, refactor the comparison to take advantage of this. This way, the code is more readable and safer. This code was detected with the help of Coccinelle, and audited and modified manually.
