[linuxkernelnewbies] User space TCP/IP

[Peter Teoh]

http://www.joerch.org/tcpip/ 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
