4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Amir Goldstein <[email protected]> commit 93f38b6fae0ea8987e22d9e6c38f8dfdccd867ee upstream. printk format used %*s instead of %.*s, so hostname_len does not limit the number of bytes accessed from hostname.
