crypto: tegra - Add missing CRYPTO_ALG_ASYNC

2026-03-26T09:10:58+00:00

The tegra crypto driver failed to set the CRYPTO_ALG_ASYNC on its asynchronous algorithms, causing the crypto API to select them for users that request only synchronous algorithms. This causes crashes (at least). Fix this by adding the flag like what the other drivers do. Also remove the unnecessary CRYPTO_ALG_TYPE_* flags, since those just get ignored and overridden by the registration function anyway.

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

host1x: Make remove callback return void

2026-01-13T11:25:38+00:00

The return value of struct device_driver::remove is ignored by the core (see device_remove() in drivers/base/dd.c). So it doesn't make sense to let the host1x remove callback return an int just to ignore it later. So make the callback return void. All current implementors return 0, so they are easily converted.

crypto: tegra - Use int type to store negative error codes

2025-09-13T04:11:06+00:00

Change the 'ret' variable in tegra_sha_do_update() from unsigned int to int, as it needs to store either negative error codes or zero returned by tegra_se_host1x_submit(). No effect on runtime. Signed-off-by: Qianfeng Rong Signed-off-by: Herbert Xu

crypto: tegra - Remove the use of dev_err_probe()

2025-08-30T07:43:26+00:00

Logging messages that show some type of "out of memory" error are generally unnecessary as there is a generic message and a stack dump done by the memory subsystem. These messages generally increase kernel size without much added value[1]. The dev_err_probe() doesn't do anything when error is '-ENOMEM'. Therefore, remove the useless call to dev_err_probe(), and just return the value instead.

crypto: tegra - Fix IV usage for AES ECB

2025-04-07T05:22:25+00:00

Modifying the crypto_request turns out to be not the right way to handle the stale value issue with the IV. Though the IV is not used for AES ECB, it eventually get used in algorithms like LRW in the next step after AES ECB encryption/decryption. Setting req->iv to NULL breaks the implementation of such algorithms. Hence modify only the local reqctx to check for IV.
