Is there interest in adding L2TP support? I have a patch which could be submitted for review. The PPPoL2TP driver presents a PPPoX socket to userspace pppd in the same way as the PPPoE and PPPoATM drivers. The kernel handles all data traffic, while userspace daemons do L2TP and PPP control message processing.
I posted an initial version of the patch in Sept 2004 (!). There was some discussion about the use of PPPoX for L2TP in the following thread: http://marc.info/?l=linux-netdev&m=109571479604766&w=2 In that thread, I was asked to improve the scalability of my solution by avoiding the socket-per-session usage imposed by the PPPoX model. I spent some time on this but was unable to come up with a better solution than the original. Since then, the original PPPoX-based solution has matured and is now use successfully by more than one L2TP protocol implementation. My original work has been kept up to date with the current kernel so could be submitted again if people want it. I didn't want to repost it without revisiting the above thread first though... :) Shall I post the patch? -- James Chapman Katalix Systems Ltd http://www.katalix.com Catalysts for your Embedded Linux software development - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
