I think PMTU etc. should be moved out of the route into a some form of flow cache. It's currently using rt6_lookup() which even goes through the rules. Doing a few thousand trie lookups after Patrick's changes in the worst case for every redirect might be acceptable but doing so for every PMTU update could become an issue. > Actually, if we're adding policy routing, we should seriously consider > whether living without a routing cache is still viable or not because > the cost of a route lookup has just gone up.
