RE : [lwip-devel] Does UDP-Lite sending really work?

[Frédéric BERNON]

Now I have study this part of the code, I have the same question. You're right, it seems strange (even if I never use UDPLITE, due to the socket layer).

Objet : [lwip-devel] Does UDP-Lite sending really work?

As it is now, on sending over a udp-lite udp_pcb, the checksum is generated with a pseudo header containing IP_PROTO_UDP as protocol information. On receiving, however, IP_PROTO_UDPLITE is used for checking. Also, when sending using ip_output IP_PROTO_UDPLITE is used.

Shouldn't IP_PROTO_UDPLITE also be used to generate the checksum or am I missing something???
