Good to hear. I'm waiting on a bit more feedback but I think I'll be
checking this in soon, with a big comment talking about the
performance implications etc.
So wait a second; what was the m_pullup vs. m_dup thing? Has anyone
actually tried that? I mean using a sledgehammer if a mitten would be
enough is kind of .. uhm. You get it.
Perhaps I'm confused, I've been off dealing with other issues for a
few days, but m_pullup doesn't make a copy of the packet or its
fields, only makes sure that it's contiguous in memory. Am I wrong in that?
Since the bug is that two pieces of code modify the same data, in ways
that interfere, I'm not sure how we can avoid making a copy. It might
be nice to limit the copy, but we'd still need two copies, one for the
loopback device and one for the real device.
pull the headers up. copy just the headers. no deep copy.
