I can see from the list that Thomas Jacob <jacob@xxxxxxxxxxxxx>, and I have just posted patches solving the same issue. I promised Patrick that I would work on this issue, and I did. Its running on our production servers, and I planned to release the patch today as it has proven stable on production. I guess Thomas was just slightly faster than me ;-) It was actually already released in the CPAN module IPTables::libiptc (ver.0.08 released 2008-06-16). We both use binary search, but with two slightly different approaches. - My patch uses the existing data structure, and the existing algorithm for binary searching. - Thomas builds a new data structure and implements a new binary search algorithm. I must give Thomas that this binary search algo (taken from wikipedia) is much more compact than the existing one. Guess I cannot judge what patch is the best, as I'm biased... -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
