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

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/zip - add lz4 algorithm for hisi_zip

2026-01-31T02:52:31+00:00

Add the "hisi-lz4-acomp" algorithm by the crypto acomp. When the 8th bit of the capability register is 1, the lz4 algorithm will register to crypto acomp, and the window length is configured to 16K by default. Since the "hisi-lz4-acomp" currently only support compression direction, decompression is completed by the soft lz4 algorithm. Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon/zip - support fallback for zip

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

When the hardware queue resource busy(no shareable queue) or memery alloc fail in initialization of acomp_alg, use soft algorithm to complete the work. Fixes: 1a9e6f59caee ("crypto: hisilicon/zip - remove zlib and gzip") Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

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 - centralize the sending locks of each module into qm

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

When a single queue used by multiple tfms, the protection of shared resources by individual module driver programs is no longer sufficient. The hisi_qp_send needs to be ensured by the lock in qp.

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.

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

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

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 - enable error reporting again

2025-09-20T12:21:04+00:00

When an error occurs on the device, an interrupt is reported. When the firmware forwards the interrupt to the driver and masks the error. If the driver does not enable error reporting when an error does not need to be reset, the device does not report the error to the driver when the error occurs again. Therefore, after the driver obtains the information, the error reporting needs to be enabled again. Signed-off-by: Weili Qian Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon/qm - mask axi error before memory init

2025-09-20T12:21:03+00:00

After the device memory is cleared, if the software sends the doorbell operation, the hardware may trigger a axi error when processing the doorbell. This error is caused by memory clearing and hardware access to address 0. Therefore, the axi error is masked during this period.
