crypto: hisilicon - Fix dma_unmap_single() direction

2026-06-01T15:29:20+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/sec2 - fix for aead auth key length

2025-04-10T12:30:58+00:00

[ Upstream commit 1b284ffc30b02808a0de698667cbcf5ce5f9144e ] According to the HMAC RFC, the authentication key can be 0 bytes, and the hardware can handle this scenario. Therefore, remove the incorrect validation for this case.

crypto: hisilicon/qm - inject error before stopping queue

2025-03-13T11:47:44+00:00

commit b04f06fc0243600665b3b50253869533b7938468 upstream. The master ooo cannot be completely closed when the accelerator core reports memory error. Therefore, the driver needs to inject the qm error to close the master ooo. Currently, the qm error is injected after stopping queue, memory may be released immediately after stopping queue, causing the device to access the released memory. Therefore, error is injected to close master ooo before stopping queue to ensure that the device does not access the released memory.

[ Upstream commit c977950146720abff14e46d8c53f5638b06a9182 ] This error handling looks really strange. Check if the string has been truncated instead.

crypto: hisilicon: Wipe entire pool on error

[ Upstream commit aa85923a954e7704bc9d3847dabeb8540aa98d13 ] To work around a Clang __builtin_object_size bug that shows up under CONFIG_FORTIFY_SOURCE and UBSAN_BOUNDS, move the per-loop-iteration mem_block wipe into a single wipe of the entire pool structure after the loop.

crypto: hisilicon/qm - add missing pci_dev_put() in q_num_set()

2023-01-14T09:15:49+00:00

[ Upstream commit cc7710d0d4ebc6998f04035cde4f32c5ddbe9d7f ] pci_get_device() will increase the reference count for the returned pci_dev. We need to use pci_dev_put() to decrease the reference count before q_num_set() returns.
