However\nrpcrdma_ep_create() currently stores that pointer in ep->re_id only\nafter rpcrdma_create_id() returns.\n\nA local administrator can race an NFS/RDMA mount against RDMA device\nremoval. If rpcrdma_remove_one() observes the just-registered\nnotification before rpcrdma_ep_create() assigns ep->re_id,\nrpcrdma_ep_removal_done() calls trace_xprtrdma_device_removal(NULL).\nThe tracepoint dereferences id->device->name and copies\nid->route.addr.dst_addr, so the callback can crash the kernel with a\nNULL pointer dereference.\n\nStore the rdma_cm_id in ep->re_id immediately before publishing\nep->re_rn. The existing error path still destroys the id directly if\nregistration fails; ep is then freed by the caller without using\nep->re_id. Remove the later duplicate assignment in rpcrdma_ep_create()."
