This could lead # to values wrapping around and a smaller allocation being made than the # caller was expecting. Using those allocations could lead to linear # overflows of heap memory and other misbehaviors. # # So, use the struct_size() helper to do the arithmetic instead of the # argument "size + count * size" in the kzalloc() function. # # [1] https://www.kernel.org/doc/html/v5.14/process/deprecated.html#open-coded-arithmetic-in-allocator-arguments # # Signed-off-by: Len Baker # Reviewed-by: Gustavo A.
