rtcache_init and rtcache_init_noclone lookup ro_dst and store the result in ro_rt, taking care of the reference counting and calling the domain specific route cache. rtcache_free checks if a route was cashed and frees the reference. rtcache_copy copies ro_dst of the given struct route, checking that enough space is available and incrementing the reference count of the cached rtentry if necessary. rtcache_check validates that the cached route is still up. If it isn't, it tries to look it up again. Afterwards ro_rt is either a valid again or NULL. rtcache_copy is used internally. Adjust to callers of rtalloc/rtflush in the tree to check the sanity of ro_dst first (if necessary). If it doesn't fit the expectations, free the cache, otherwise check if the cached route is still valid. After that combination, a single check for ro_rt == NULL is enough to decide whether a new lookup needs to be done with a different ro_dst. Make the route checking in gre stricter by repeating the loop check after revalidation. Remove some unused RADIX_MPATH code in in6_src.c. The logic is slightly changed here to first validate the route and check RTF_GATEWAY afterwards. This is sementically equivalent though. etherip doesn't need sc_route_expire similiar to the gif changes from dyoung@ earlier. Based on the earlier patch from dyoung@, reviewed and discussed with him. |
