Mon 07 Nov 2016 11:28:59 AM UTC, comment #1: This turns out to be a bigger problem. Even if I remove the assertion in socket.c and implement IPv6 mapped IPv4 address handling, the lower layers cannot deal correctly with IP versions that change from call to call.

Using sento() on a IPv6 UDP socket to a v4 address fails in current version. In the function udp_sendto_if_chksum(), src IP is returned as null.

Thanks David for testing!
I assume that it also works with sockets (at least I tested it with the Ping code of unix simhost).
Would have been interesting to get feedback from a "real world" application. Too bad the OP did not provide feedback any more.
