icmp: randomize the global rate limiter

2020-10-29T09:07:05+00:00

[ Upstream commit b38e7819cae946e2edf869e604af1e65a5d241c5 ] 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.

mlxsw: spectrum: Use different trap group for externally routed packets

2020-07-29T19:16:21+00:00

Cited commit mistakenly removed the trap group for externally routed packets (e.g., via the management interface) and grouped locally routed and externally routed packet traps under the same group, thereby subjecting them to the same policer. This can result in problems, for example, when FRR is restarted and suddenly all transient traffic is trapped to the CPU because of a default route through the management interface. Locally routed packets required to re-establish a BGP connection will never reach the CPU and the routing tables will not be re-populated. Fix this by using a different trap group for externally routed packets.
