The change was in 5.9, with this commit to in_pcb.c: ---------------------------- revision 1.178 date: 2015/09/11 13:59:27; author: vgross; state: Exp; lines: +3 -7; commitid: NyNuX1q0M9Dwr560; Stricter checks on sockaddr content when binding PF_INET sockets. Ok mpi@ ---------------------------- Unless this is just the most recent in a series of similar reports, I doubt we'll back this out or revise the check; it's just old code, written in the slightly sloppy style of the time. > Looking at the code in ttcp.c the problem seems to be that the field > sin_family in the structure sockaddr_in (sinme) is not initialized. > > By adding sinme.sin_family = AF_INET; before bind(...) the program works > fine. No specific maintainer on the port, so I suggest you send your diff to po...@openbsd.org, so it can be included in ports and packages going forward. Philip Guenther
