Right now, the supporting sysctls to do this aren't present; the getcred sysctl is present but based on a rather stale version of the TCP code of the same nature, and the lookup to query the lists, etc, isn't present at all. We should add these, but let's try and do a better job than with what we have now -- we should make a clean distinction between the user and kernel data structures, and not have the external ones include nested copies of internal ones, etc, as this makes netstat very fragile in the face of kernel changes. Once or twice I've started unwinding the mess that is the xfoo data structures for TCP, but I usually give up quickly. :-) Robert N M Watson Computer Laboratory University of Cambridge
