I think the issue is that there's a window between the creation of a new ucma_context and it being associated with an rdma_cm_id. A caller could exploit this window to cause a NULL pointer dereference. The ctx itself would be valid, but the cm_id still not set. The use of an invalid ctx should be trapped already. The change itself looks reasonable. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
