Did we ever do anything with this? This seems like a wonderful opportunity.<br>

The catch may be that ntpd needs to know which interface a packet arrived on, <br>
actually the destination IP address.<br>

You missed some interesting discussion on IRC last night (for after<br>
release). While working on the CVEs Daniel has spotted that all the<br>
iteration-over-interfaces stuff (which is 75% of ntp_io.c and almost<br>
all of what's left of the ISC library) is unnecessary if we trust<br>
IPv4/IPv6 wildcard addresses to work (which are POSIX).<br>
<br>
This is kind of a big deal not just because of the LOC reduction but<br>
because it would let us sever a major and several minor platform<br>
dependencies - not just getifaddrs but the routing-sockets stuff as<br>
well.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">My rat brain is whispering 'no'.
