The init_conns() and stop-and-destroy paths then call\ndestroy_con_cq_qp() while cq is still NULL (no PUT) and only afterwards\nrdma_destroy_id().\n\nCMA serializes the handler against rdma_destroy_id() with handler_mutex,\nbut that does not order the GET against destroy_con_cq_qp(). If\nADDR_RESOLVED has already passed the DESTROYING check, it can take\ncon_mutex, GET credits, and then lose the con to kfree. Device\nunregister later hits WARN_ON(cq->cqe_used) in ib_cq_pool_cleanup().\n\nSet a per-connection flag under con_mutex before CQ/QP teardown so a\nracing ADDR_RESOLVED cannot borrow credits after teardown has begun.","state":0,"publishedAt":"2026-10-06T08:46:40.151+00:00","modifiedAt":"2026-10-19T09:18:03.073+00:00","affected":[{"ecosystem":"Vendor
