Yes, I've seen this declared in other reports too.
It probably means just that for window scales of 0..2 the misinterpretation does not result in a too-small-to-send-data window.
But I'm still confused that the scaled window is being given to the receiver, and this makes the connection freeze. I wonder if there is a queer box doing NAT or similar in front of the gentoo machine which either:
1) Applies any window scaling to both directions 2) Applies window scaling to the wrong direction
and uses this to "help" with dropping of out-of-window TCP segments. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
