Netstat depends on specific structures in kernel memory, ipfw depends on specific ioctls whose arguments may vary. Netstat in particular breaks on head on a quasi daily basis because of changes to networking structures. STABLE implies STABLE for things that depend on libc and are not dependent on obscure kernel interfaces. There is some work going on (off and on) to decouple netstat from kvm which would fix that. N-1 compatibility for ipfw is probably possible, anything more than that is probably infeasible from an interface tracking standpoint. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
