crypto: hisilicon - Fix dma_unmap_single() direction

2026-04-12T08:46:29+00:00

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 - remove unused and non-public APIs for qm and sec

2026-04-12T08:46:29+00:00

- sec_register_to_crypto() and sec_unregister_from_crypto() have been removed, the function declarations have not been removed. Remove them. - hisi_qm_start_qp and hisi_qm_stop_qp are called internally by the QM. Therefore, the EXPORT_SYMBOL_GPL declaration of these non-public interfaces is deleted.

crypto: hisilicon/qm - drop redundant variable initialization

2026-04-12T08:46:29+00:00

Variables are assigned before used. Initialization is not required. Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon/qm - remove else after return

Else condition is not needed after a return, remove it. Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon/qm - add const qualifier to info_name in struct qm_cmd_dump_item

2026-04-12T08:46:28+00:00

The "info_name" is never changed in struct qm_cmd_dump_item, make it const. Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon - fix the format string type error

2026-04-12T08:46:28+00:00

1. The return value val of sec_debugfs_atomic64_get is of the u64 type, but %lld instead of %llu is used in DEFINE_DEBUGFS_ATTRIBUTE. Fix it. 2. In debugfs.c, since the types of q_depth and xeq_depth are u16, the results of q_depth - 1 and xeq_depth - 1 are int rather than u16. Use %d for int.

crypto: hisilicon/hpre - Use crypto_stdrng_get_bytes()

2026-04-03T00:56:12+00:00

Replace the sequence of crypto_get_default_rng(), crypto_rng_get_bytes(), and crypto_put_default_rng() with the equivalent helper function crypto_stdrng_get_bytes(). Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: hisilicon/sec2 - prevent req used-after-free for sec

2026-03-27T09:52:44+00:00

During packet transmission, if the system is under heavy load, the hardware might complete processing the packet and free the request memory (req) before the transmission function finishes. If the software subsequently accesses this req, a use-after-free error will occur. The qp_ctx memory exists throughout the packet sending process, so replace the req with the qp_ctx.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds
