User space TCP/IP

I'm implementing an IP stack outside the kernel via the packet filter mechanism.

Status of implementation

Already implemented:

• ARP queries, reply to ARP queries

• Ethernet broadcast

• Static routing

• IP fragmentation and reassembly

• Reply to ICMP echo requests (ping)

• Refuse UDP packets and TCP connection requests

• Regularly broadcast rwho status messages

• A partial implementation of the TCP discard service

Still missing:

• Accept broadcast packets

• Path MTU discovery

• Evaluate ICMP redirect messages

• Reassemble reordered TCP segments

• Resend lost TCP SYN and FIN segments

• Send TCP data

To the projects overview.
