I was thinking of things like ypbind, which does not do a bind(0), but generates its own "random" port, and it will grab that port if you don't do anything in userspace to prevent it. I'm perfectly aware that this is not the case that is intended to be addressed by this patch. But if you want to solve this problem, why not the one that is addressed by the patch?

I must be starting to sound like I have something against this patch, which is not the case, so I'll drop it here.

huh, I wasn't aware that there was software out there that did that sort of thing. I see the fix for this being fairly simple, change misbehaving programs like ypbind to either use fixed, configurable ports, or if they don't care, do bind(0) (or just don't run them on any system you want to be reliable ;-)
