@centaurian: Done. Given the fact that I probably won't be able to release it properly for a few days, here's the updated dropbear binary. (Just overwrite the one in usbnet/bin with this one, and restart sshd [by switching usbnet off/on]).
It'll also be useful to check that my patch indeed works as intended, and that I didn't break anything
. (ie. still auth properly over wifi when not connecting from localhost ^^)
