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 - 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/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.

crypto: hisilicon - add device load query functionality to debugfs

2026-03-22T02:17:59+00:00

The accelerator device supports usage statistics. This patch enables obtaining the accelerator's usage through the "dev_usage" file. The returned number expressed as a percentage as a percentage. Signed-off-by: Zongyu Wu Signed-off-by: Herbert Xu

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

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

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

2026-01-16T06:02:06+00:00

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 - consolidate qp creation and start in hisi_qm_alloc_qps_node

2026-01-16T06:02:06+00:00

Consolidate the creation and start of qp into the function hisi_qm_alloc_qps_node. This change eliminates the need for each module to perform these steps in two separate phases (creation and start). Signed-off-by: Chenghai Huang Signed-off-by: Weili Qian Signed-off-by: Herbert Xu

crypto: hisilicon/qm - enhance the configuration of req_type in queue attributes

2026-01-16T06:02:06+00:00

Originally, when a queue was requested, it could only be configured with the default algorithm type of 0. Now, when multiple tfms use the same queue, the queue must be selected based on its attributes to meet the requirements of tfm tasks. So the algorithm type attribute of queue need to be distinguished. Just like a queue used for compression in ZIP cannot be used for decompression tasks.
