John's packet dump (DHCP messages only).

I went through the packet dump once more but haven't been able to find anything strange (I was hoping to see some big values in some time option or something like that).

I set up a server/client to be as much as possible to John's server/client.
I tried to reproduce the problem here but with no luck.

So although we don't have a reproducer, we know where in the code the problem is, that it's a security problem (DoS) and we have a patch that John confirmed as fixing it.

To security response team:
What's the next step ? Can I report this upstream (<email address hidden>) ?
