However, currently we try to also delete all nexthops we haven't even tried to add yet so that a "ip route add" command can actually remove pre-existing routes if it fails. (2) Attempt to replace a multipath route results in a broken siblings linked list. Following commands (like "ip route del") can then either follow a link into freed memory or end in an infinite loop (if the slab object has been reused). v2: fix an omission in first patch v3: change the semantics of replace operation to better match IPv4 ==================== Signed-off-by: David S.
