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

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/qm - set NULL to qm->debug.qm_diff_regs

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

When the initialization of qm->debug.acc_diff_reg fails, the probe process does not exit. However, after qm->debug.qm_diff_regs is freed, it is not set to NULL. This can lead to a double free when the remove process attempts to free it again. Therefore, qm->debug.qm_diff_regs should be set to NULL after it is freed.

crypto: hisilicon/debugfs - fix the struct pointer incorrectly offset problem

2024-12-10T05:40:25+00:00

Offset based on (id * size) is wrong for sqc and cqc. (*sqc/*cqc + 1) can already offset sizeof(struct(Xqc)) length. Fixes: 15f112f9cef5 ("crypto: hisilicon/debugfs - mask the unnecessary info from the dump") Cc: Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon/debugfs - Resolve the problem of applying for redundant space in sq dump

2024-04-12T07:07:53+00:00

When dumping SQ, only the corresponding ID's SQE needs to be dumped, and there is no need to apply for the entire SQE memory. This is because excessive dump operations can lead to memory resource waste. Therefor apply for the space corresponding to sqe_id separately to avoid space waste.

crypto: hisilicon/debugfs - Fix the processing logic issue in the debugfs creation

2024-04-12T07:07:52+00:00

There is a scenario where the file directory is created but the file attribute is not set. In this case, if a user accesses the file, an error occurs. So adjust the processing logic in the debugfs creation to prevent the file from being accessed before the file attributes such as the index are set.

crypto: hisilicon/debugfs - Fix debugfs uninit process issue

2024-04-12T07:07:52+00:00

During the zip probe process, the debugfs failure does not stop the probe. When debugfs initialization fails, jumping to the error branch will also release regs, in addition to its own rollback operation. As a result, it may be released repeatedly during the regs uninit process. Therefore, the null check needs to be added to the regs uninit process.

crypto: hisilicon/qm - obtain stop queue status

2024-02-17T01:09:16+00:00

The debugfs files 'dev_state' and 'dev_timeout' are added. Users can query the current queue stop status through these two files. And set the waiting timeout when the queue is released. dev_state: if dev_timeout is set, dev_state indicates the status of stopping the queue. 0 indicates that the queue is stopped successfully. Other values indicate that the queue stops fail. If dev_timeout is not set, the value of dev_state is 0; dev_timeout: if the queue fails to stop, the queue is released after waiting dev_timeout * 20ms.
