Subject: [OT] use of patented algorithms in the kernel ok or not?
Date: Thu, 18 Dec 2003 18:11:37 -0500	[thread overview]
Message-ID: <20031218231137.GA13652@gnu.org> (raw)

Hi,

Apologies for posting this OT question here, I didn't find this question
answered in the FAQ.

There's a fast algorithm for longest-prefix match (as used in IPv4 routing
table lookups) which I have implemented, and would like to submit for
inclusion into the kernel (when 2.7 opens.)

However, I am aware that there is a patent on this algorithm, exclusively
licensed to a major manufacturer of networking equipment.

What am I to do?  Ignore the patent?  Or should I refrain from submitting
the patch I wrote, and look for an unencumbered algorithm instead?


thanks,
Lennert
