zhenwei pi 8c9c034325 nvme-rdma: handle unexpected nvme completion data length ... [ Upstream commit 25c1ca6eca ] Receiving a zero length message leads to the following warnings because the CQE is processed twice: refcount_t: underflow; use-after-free. WARNING: CPU: 0 PID: 0 at lib/refcount.c:28 RIP: 0010:refcount_warn_saturate+0xd9/0xe0 Call Trace: <IRQ> nvme_rdma_recv_done+0xf3/0x280 [nvme_rdma] __ib_process_cq+0x76/0x150 [ib_core] ... Sanity check the received data length, to avoids this. Thanks to Chao Leng & Sagi for suggestions.
