Folks, Well, I think the time is nigh that we started getting of our butts and getting on with some code! I'm cc'ing this to Travis so he can comment if he feels like it :) To bring folks up to date, I've written a tulip net driver, BGA was working on an Ne2K driver and the rtl8139 driver works OK. Newos now has a rudimentary network stack that does - arp - ipv4 - icmp - udp Basically, I think we should move to Milestone #2 and start working on an ARP cache. However, I don't really want it to be limited to being an arp cache, but rather a net cache. I've been doing some work on IPv6 and actually have some working code, but it has shown some of the things that are needed. Essentially we need a general purpose net cache that we can use in a few different places. For instance... - provide ipv4 <-> ethernet MAC address translation - provide a quick means of looking up routing information - ipv6 <-> ethernet MAC - ipv6 router details - list of ipv4/ipv6 addresses for an interface The list is quite long and varied. The existing code in newos can be found in http://www.newos.org/cgi-bin/perfbrowse.perl?@filelog+//depot/newos/kernel/n et/arp.c http://www.newos.org/cgi-bin/perfbrowse.perl?@filelog+//depot/newos/kernel/n et/ipv4.c Now, using a hash is a good idea as it should provide good performance, but the hashing methd will need to be flexible as an ipv4 address is 32 bits, v6 is 128 bits! Also in v6 there is a need to do lookup's using parts of the address, i.e. using only the first 10 bits for checking we only have a single link-local address registered with an interface. The net stack (as currently implemented) is nice and straightforward, so hopefully the cost od getting involved is still low enough that folks can jump into this quite quickly. Can this all be accomplished? I think so and we have some good code to start from and no shortage of places to look for inspiration! So, shall we start coding? Shall we also add a channel to irc.openprojects.net for us to use? openbeosnetworking or some such? david
