An incorrect implementation of any congestion control algorithm has ramifications not considered when the congestion control author verified the design of his algorithm.
This has a large impact on every user on the internet, not just Linux machines.
Perhaps on a microscopic scale "this" part of the BIC algorithm was just behaving Reno-like due to the bug, but what implications does that error have as applied to the other heuristics in BIC? This is what I'm talking about. BIC operates in several modes, one of which is a pseudo binary search mode, and another is a less aggressive slower increase mode.
Therefore I think fixes to congestion control algorithms which are enabled by default always should take a high priority in the stable kernels. - 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/
