Goldwyn Rodrigues 8b259b9965 ima: open a new file instance if no read permissions ... commit a408e4a86b upstream. Open a new file instance as opposed to changing file->f_mode when the file is not readable. This is done to accomodate overlayfs stacked file operations change. The real struct file is hidden behind the overlays struct file. So, any file->f_mode manipulations are not reflected on the real struct file. Open the file again in read mode if original file cannot be read, read and calculate the hash.
