Title
nvmet-rdma: fix response resource leak on queue teardown
Summary
In the Linux kernel, the following vulnerability has been resolved: nvmet-rdma: fix response resource leak on queue teardown When an nvme target with rdma transport is removed while I/Os are in flight, a response can be posted but its send completion is never delivered before the connection is torn down. As a result nvmet_rdma_send_done() and nvmet_rdma_release_rsp() are never called for the response, and this leaks the allocated RDMA read/write context and request SGLs. These leaks are recreated by running blktests nvme/061 with the rdma transport and the siw driver. Kernel kmemleak feature reports them as follows: unreferenced object 0xffff88812bc490c0 (size 32): comm "kworker/2:1H", pid 409, jiffies 4307744490 backtrace (crc 89afd339): __kmalloc_noprof+0x5f9/0x890 sgl_alloc_order+0x7b/0x380 nvmet_req_alloc_sgls+0x290/0x4f0 [nvmet] nvmet_rdma_map_sgl_keyed+0x241/0x12e0 [nvmet_rdma] nvmet_rdma_handle_command+0x73e/0xb80 [nvmet_rdma] __ib_process_cq+0x149/0x4c0 [ib_core] ib_cq_poll_work+0x49/0x160 [ib_core] process_one_work+0x8b2/0x1640 worker_thread+0x5fd/0xfe0 kthread+0x367/0x460 ret_from_fork+0x655/0x9d0 ret_from_fork_asm+0x1a/0x30 unreferenced object 0xffff88814bd05e80 (size 64): comm "kworker/3:1H", pid 148, jiffies 4295195428 backtrace (crc e35510cb): __kmalloc_noprof+0x5f9/0x890 rdma_rw_ctx_init+0x333/0x1fa0 [ib_core] nvmet_rdma_map_sgl_keyed+0x5c8/0x12e0 [nvmet_rdma] nvmet_rdma_handle_command+0x73e/0xb80 [nvmet_rdma] __ib_process_cq+0x149/0x4c0 [ib_core] ib_cq_poll_work+0x49/0x160 [ib_core] process_one_work+0x8b2/0x1640 worker_thread+0x5fd/0xfe0 kthread+0x367/0x460 ret_from_fork+0x655/0x9d0 ret_from_fork_asm+0x1a/0x30 To avoid the memory leaks, reclaim the memory of the in-flight responses when the queue QP is torn down. Call nvmet_rdma_free_rsp_resources() that frees up the RDMA read/write context and the request SGLs of such responses.

I/O that reaches nvmet_rdma_map_sgl_keyed only needs nvmet_req_init to succeed; nvmet_check_auth_status is true unless a DH-HMAC-CHAP host_key is configured, and nvmet_host_allowed admits a client-supplied host NQN or allow_any_host.\nUI:N - The attacker submits the keyed-SGL capsule and disconnects its own RDMA connection; nvmet_rdma_cm_handler delivers RDMA_CM_EVENT_DISCONNECTED into nvmet_rdma_queue_disconnect with no local user or administrator action.\nS:U - The leaked sgl_alloc pages and rdma_rw_ctx sit in the nvmet-rdma target kernel\u0027s allocator; the bug does not cross a VM, IOMMU, or other security-authority boundary.\nC:N - nvmet_rdma_destroy_queue_ib frees the QP without calling nvmet_rdma_free_rsp_resources, so the SGL pages and rdma_rw_ctx are orphaned. Those objects are never copied back to the initiator or otherwise disclosed.\nI:N - The orphaned scatterlist from nvmet_req_alloc_sgls and the rdma_rw_ctx from rdma_rw_ctx_init are leaked, not reused, so there is no write primitive, use-after-free, or kernel-state corruption.\nA:H - Each in-flight keyed-SGL command leaks the pages sgl_alloc obtained (up to 2^NVMET_RDMA_MAX_MDTS * 4KB, 1MB) plus the rdma_rw_ctx. Repeating RDMA connect, queue-depth READs, and RDMA_CM_EVENT_DISCONNECTED exhausts kernel memory and can OOM the target."
