I already commented on this earlier in this thread - or some other
related thread, I've lost track, but both you and Steve were on the
To/CC line - last time I checked, you can't reliably link packets to
the sender/subject in the netfilter hooks (I'll be shocked if this has
changed). The best you can do in some cases is to link the packet to
the socket, and that isn't going to help you.
Ok, thanks for this clarification. Maybe I'm mis-remembering what user
information is available in software interrupts rather than user
context. This will need more investigation...
