No, the advisory was not fake. At the time, I didn't
realise that -1 or any negative will not get past
sys_setsockopt(). Without the sanity check in
setsockopt, there would be a bad security issue,
though. It's still worth upgrading, anyway. The bug
exists, just not a very big possibility of exploiting.
Thank you for your time.
Shaun.
