It does bind on any other address in the system, including 0.0.0.0 (INADDR_ANY). The latter still doesn't allow incoming SCTP connections on that address though (although instead of "connection refused" I get hanging connect()).
I've looked through both netgraph and sctp source code. netgraph creates IFT_PROPVIRTUAL interfaces, and there is a function in sctp called sctp_is_desired_interface_type. The latter doesn't think that IFT_PROPVIRTUAL is something desirable. I believe it's a bug, because netgraph is a generic framework, and there is no reason to not allow creation of SCTP sockets on its interfaces. For instance, I use L2TP provided by mpd5 as main internet connection. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
