I am working on some ppp bugs and I noticed there is an excellent kernel patch for MPPE/MPPC available for both 2.4 and 2.6 kernel versions: http://www.polbox.com/h/hs001/ There have been existing patches similar to this one available for a long time. However, the author of this patch effectively differentiates his patches here: "Some day, digging in the Net, I found MPPE implementation at http://mirror.binarix.com/ppp-mppe/. I thought that it would be good to complete that code with MPPC and make it freely available. So I wrote MPPC part and added support for 56 bit keys in MPPE." There may be some copyright issues with this patch. Here is another relavent quote from the above website: "Although the module's source code is completely free, MPPC itself is patented algorithm. Patent for *Microsoft* PPC is holded by the Hifn Inc. This is obvious ;-). Furthermore, MPPE uses RC4 encryption algorithm which itself isn't patented, but RC4 is trademark of RSA Data Security Inc. To avoid legal problems, US citizens shouldn't use this module." I have two questions for everyone: 1. Can I include the ppp patch in the ppp ebuild? How do I do it legally? 2. Can we include the kernel patch in the gentoo-sources base patch set? How do we do it legally? Thanks, Cory -- gentoo-dev@gentoo.org mailing list
