Hi all. I am working on some ppp bugs and I noticed there is an excellent |
2 |
kernel patch for MPPE/MPPC available for both 2.4 and 2.6 kernel versions: |

There have been existing patches similar to this one available for a long |
7 |
time. However, the author of this patch effectively differentiates his |
8 |
patches here: |

|

"Some day, digging in the Net, I found MPPE implementation at |
11 |
http://mirror.binarix.com/ppp-mppe/. I thought that it would be good to |
12 |
complete that code with MPPC and make it freely available. So I wrote MPPC |
13 |
part and added support for 56 bit keys in MPPE." |

There may be some copyright issues with this patch. Here is another |
16 |
relavent quote from the above website: |
17 |
|
18 |
"Although the module's source code is completely free, MPPC itself is |
19 |
patented algorithm. Patent for *Microsoft* PPC is holded by the Hifn Inc. |
20 |
This is obvious ;-). Furthermore, MPPE uses RC4 encryption algorithm |
21 |
which itself isn't patented, but RC4 is trademark of RSA Data Security |
22 |
Inc. To avoid legal problems, US citizens shouldn't use this module." |

I have two questions for everyone: |
25 |
1. Can I include the ppp patch in the ppp ebuild? How do I do it legally? |
26 |
2. Can we include the kernel patch in the gentoo-sources base patch set? |
27 |
How do we do it legally? |

Thanks, |
