crypto: hisilicon - Fix dma_unmap_single() direction

2026-05-07T04:09:41+00:00

commit 1ee57ab93b75eb59f426aef37b5498a7ffc28278 upstream. The direction used to map the buffer skreq->iv is DMA_TO_DEVICE but it is unmapped with direction DMA_BIDIRECTIONAL in the error path. Change the unmap to match the mapping.

crypto: hisilicon/qm - move the barrier before writing to the mailbox register

2026-03-04T12:20:58+00:00

[ Upstream commit ebf35d8f9368816c930f5d70783a72716fab5e19 ] Before sending the data via the mailbox to the hardware, to ensure that the data accessed by the hardware is the most up-to-date, a write barrier should be added before writing to the mailbox register. The current memory barrier is placed after writing to the register, the barrier order should be modified to be before writing to the register.

crypto: hisilicon/trng - support tfms sharing the device

2026-03-04T12:19:38+00:00

[ Upstream commit 3d3135057ff567d5c09fff4c9ef6391a684e8042 ] Since the number of devices is limited, and the number of tfms may exceed the number of devices, to ensure that tfms can be successfully allocated, support tfms sharing the same device.

crypto: hisilicon/sec2 - support skcipher/aead fallback for hardware queue unavailable

2026-03-04T12:19:34+00:00

[ Upstream commit e7507439628052363500d717caffb5c2241854dc ] When all hardware queues are busy and no shareable queue, new processes fail to apply for queues. To avoid affecting tasks, support fallback mechanism when hardware queues are unavailable.

crypto: hisilicon/zip - adjust the way to obtain the req in the callback function

2026-03-04T12:19:34+00:00

[ Upstream commit 19c2475ce1984cf675ebfbbeaa5509b2fb1887d6 ] In the shared queue design, multiple tfms use same qp, and one qp need to corresponds to multiple qp_ctx. So use tag to obtain the req virtual address. Build a one-to-one relationship between tfm and qp_ctx. finaly remove the old get_tag operation.

crypto: hisilicon/qm - Fix device reference leak in qm_get_qos_value

2025-11-24T09:36:01+00:00

commit 59b0afd01b2ce353ab422ea9c8375b03db313a21 upstream. The qm_get_qos_value() function calls bus_find_device_by_name() which increases the device reference count, but fails to call put_device() to balance the reference count and lead to a device reference leak. Add put_device() calls in both the error path and success path to properly balance the reference count. Found via static analysis.

crypto: hisilicon/qm - clear all VF configurations in the hardware

[ Upstream commit 64b9642fc29a14e1fe67842be9c69c7b90a3bcd6 ] When disabling SR-IOV, clear the configuration of each VF in the hardware. Do not exit the configuration clearing process due to the failure of a single VF. Additionally, Clear the VF configurations before decrementing the PM counter.

crypto: hisilicon/qm - invalidate queues in use

2025-11-13T20:34:28+00:00

[ Upstream commit 85acd1b26b8f5b838887dc965dc3aa2c0253f4d1 ] Before the device reset, although the driver has set the queue status to intercept doorbells sent by the task process, the reset thread is isolated from the user-mode task process, so the task process may still send doorbells. Therefore, before the reset, the queue is directly invalidated, and the device directly discards the doorbells sent by the process.

crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs

2025-10-15T10:00:14+00:00

[ Upstream commit f0cafb02de883b3b413d34eb079c9680782a9cc1 ] When the initialization of qm->debug.acc_diff_reg fails, the probe process does not exit. However, after qm->debug.qm_diff_regs is freed, it is not set to NULL. This can lead to a double free when the remove process attempts to free it again. Therefore, qm->debug.qm_diff_regs should be set to NULL after it is freed.
