The problem is that kernel data is being sent to userspace due to an uncleared buffer that was allocated and then copied to userspace. This can be reproduced by dumping the current set of iptables rules. Peter had an example reproducing script that he used to specifically show this. Peter, can you provide that? I thought that initializing this buffer to zero would solve the problem, but I guess I cleared the wrong buffer :( thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
