Date: Thu, 29 Nov 2001 17:27:49 +0000 Mime-Version: 1.0 Content-Type: text/plain; format=flowed Message-ID: X-OriginalArrivalTime: 29 Nov 2001 17:27:49.0401 (UTC) FILETIME=[2AD80890:01C178FB] Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I am sorry if this is a newbie's question. I am developing a kernel module which needs to call some crypt functions implemented in user space. Since those functions utilize openssl library, I assume there is no easy way to port them into kernel. I wonder whether there is an easy and elegant way to call the user space functions from the kernel and get the results, if /proc can not be used. If anybody knows where I can find a crypt library in the kernel, that will be a great help too. Thank you very much.
