Jon Paul Maloy 7d24dcdb3f tipc: avoid stale link after aborted failover ... During link failover it may happen that the remaining link goes down while it is still in the process of taking over traffic from a previously failed link. When this happens, we currently abort the failover procedure and reset the first failed link to non-failover mode, so that it will be ready to re-establish contact with its peer when it comes available. However, if the first link goes down because its bearer was manually disabled, it is not enough to reset it; it must also be deleted; which is supposed to happen when the failover procedure is finished. Otherwise it will remain a zombie link: attached to the owner node structure, in mode LINK_STOPPED, and permanently blocking any re- establishing of the link to the peer via the interface in question. We fix this by amending the failover abort procedure. Apart from resetting the link to non-failover state, we test if the link is also in LINK_STOPPED mode. If so, we delete it, using the conditional tipc_link_delete() function introduced in the previous commit.
