I quoted the standard and it does not say anything about AF_UNSPEC. So you cannot simply make such broad statements. I also don't say that this behavior should be removed. It's certainly useful, very much so in fact. But the spec calls for a "null address" to be used and that's in my understanding something different from using AF_UNSPEC. I looked through Stevens TCP Illustrated Vol 2 and it seems not to mention resetting the address at all. The POSIX spec certainly got this text from .1g. I cannot test it on other systems. If somebody has access to some certified systems (and maybe others), write a bit of code which creates a DGRAM socket, connect to one address, call connect with a "null address", then connect to another address (which likely has to use a different interface since otherwise the connect will just succeed, it seems). - -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQFG8VMF2ijCOnn/RHQRAr9NAJwLxyql0kQnMGJNaPZlRGsuB6rGEACgog88 WIWAFhuBWsjps7PdbcoumUQ= =oLxP -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
