crypto: hisilicon - Fix dma_unmap_single() direction

2026-05-17T15:13:33+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

2026-03-04T12:20:36+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

2026-03-04T12:19:33+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/trng - modifying the order of header files

2026-03-04T12:19:33+00:00

[ Upstream commit f5dd7c43022799ac5c4e3a0d445f9c293a198413 ] Header files is included Order-ref: standard library headers, OS library headers, and project-specific headers. This patch modifies the order of header files according to suggestions. In addition, use %u to print unsigned int variables to prevent overflow.

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

2026-03-04T12:19:32+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

2026-03-04T12:19:31+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

2025-11-24T09:30:08+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.
