It really assumes the universe in place before your change last night. It is very likely we'll have to revert it and look for another solution to the problem you were trying to solve. And actually I don't understand the actual bug very well. I can only assume that the core issue was that, unlike back when we had the routing cache, the fib_info nexthops are not persistent memory like the routing cache hash table was? Otherwise I can see absolutely no change in reference counting and dst destruction logic between the routing cache, and how I modified fib_info nexthop cached routes to behave. Anyways, the first patch caches routes in the nexthop exception entries. And the second patch has a global list for uncached routes so we can purge netdevice references properly when such devices are unregistered. Signed-off-by: David S.
