Eric Dumazet 8df0ffe2f3 icmp: randomize the global rate limiter ... [ Upstream commit b38e7819ca ] Keyu Man reported that the ICMP rate limiter could be used by attackers to get useful signal. Details will be provided in an upcoming academic publication. Our solution is to add some noise, so that the attackers no longer can get help from the predictable token bucket limiter.
