What's the problem with SO_ORIGINAL_DST? Could you please explain a bit why the code is not encouraging? The author of TPROXY also mentioned somewhere else that SO_ORIGINAL_DST is racy, but I'm not a kernel developer and don't understand why. Thanks!

Digging deeper, I found more explanation on StackOverflow https://stackoverflow.com/a/5814636/184061 (seems to be written by tproxy author Balazs Scheidler judging by the username).
