You've hit on a fine point I often make about how the term "security bug" is used.

I would call this a bug fix since someone has found what is probably an unintended behavior in the cubic algorithm. The cubic algorithm itself though would be a feature improving on the original tcp algorithm (nagle, if I remember right)

No a feature or enhancement mostly introduces something new, like a new algorithm for cubic congestion control, which this patch of course doesn't to, it just fixes the old one. ;)

I think it was actually multiple people.
