Milestone Description
|
||
|
|
|
||
|
|
1 network drivers
|
||
|
|
It was recognised that until the team members had
|
||
|
|
working NIC's there was little point in trying to
|
||
|
|
develop a network stack.
|
||
|
|
|
||
|
|
STATUS: rtl8139 in repository
|
||
|
|
tulip driver written covering Netgear FA310TX
|
||
|
|
Ne2000 driver started
|
||
|
|
|
||
|
|
2 Encapsulation
|
||
|
|
Ethernet packets come in 2 basic forms,
|
||
|
|
ethernet encapsulation (rfc 894)
|
||
|
|
IEEE 802.2/3/4/5 (rfc1042)
|
||
|
|
We need to be able to handle both. However, we only
|
||
|
|
MUST be able to send ethernet compatible frames. In pactice
|
||
|
|
we should try to send the frame in the same format that it
|
||
|
|
was received. In fact we may want to store the format used by
|
||
|
|
hosts?
|
||
|
|
|
||
|
|
David says this isn't easy to do with the current newos
|
||
|
|
stack design.
|
||
|
|
|
||
|
|
STATUS: newos has ethernet support, but with the current
|
||
|
|
architecture it's difficult to add fully transparent
|
||
|
|
support for other encapsulations.
|
||
|
|
|
||
|
|
3 ARP module
|
||
|
|
Once we can get frames from the network, one of the first
|
||
|
|
things we need to do is start capturing and caching ARP
|
||
|
|
requests.
|
||
|
|
NB david thinks this should be aimed at providing more
|
||
|
|
general purpose caching so it's useful beyond ARP. he
|
||
|
|
suggests we call this a Net Cache module.
|
||
|
|
|
||
|
|
STATUS: newos has an arp module, though cache needs work
|
||
|
|
and is limited to ipv4
|
||
|
|
|
||
|
|
4 IPv4 checksums + routing
|
||
|
|
Implement IPv4 checksums and routing
|
||
|
|
|
||
|
|
STATUS: newos has a basic version of thisi
|
||
|
|
|
||
|
|
5 IPv4 ICMP
|
||
|
|
Add ICMP support to out IPv4 module
|
||
|
|
|
||
|
|
6 IPv4 Fragmentation
|
||
|
|
This will be interesting, adding support for reconstructing
|
||
|
|
and deconstructing packets into suitable frames for transport.
|
||
|
|
NB this needs to be abel to deal with different sizes of
|
||
|
|
frame.
|
||
|
|
|
||
|
|
STATUS:
|
||
|
|
|
||
|
|
7 TCP/UDP
|
||
|
|
|
||
|
|
STATUS: newos has rudimentary UDP support
|
||
|
