Roland Dreier b13912bbb4 IPoIB: Call skb_dst_drop() once skb is enqueued for sending ... Currently, IPoIB delays collecting send completions for TX packets in order to batch work more efficiently. It does skb_orphan() right after queuing the packets so that destructors run early, to avoid problems like holding socket send buffers for too long (since we might not collect a send completion until a long time after the packet is actually sent). However, IPoIB clears IFF_XMIT_DST_RELEASE because it actually looks at skb_dst() to update the PMTU when it gets a too-long packet. This means that the packets sitting in the TX ring with uncollected send completions are holding a reference on the dst. We've seen this lead to pathological behavior with respect to route and neighbour GC. The easy fix for this is to call skb_dst_drop() when we call skb_orphan(). Also, give packets sent via connected mode (CM) the same skb_orphan() / skb_dst_drop() treatment that packets sent via datagram mode get.
