linux-toradex.git/drivers/crypto/atmel-aes.c, branch v7.2-rc5

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of  by the more specific
 where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

crypto: atmel-aes - guard unregister on error in atmel_aes_register_algs

2026-03-22T02:17:58+00:00

Ensure the device supports XTS and GCM with 'has_xts' and 'has_gcm'
before unregistering algorithms when XTS or authenc registration fails,
which would trigger a WARN in crypto_unregister_alg().

Currently, with the capabilities defined in atmel_aes_get_cap(), this
bug cannot happen because all devices that support XTS and authenc also
support GCM, but the error handling should still be correct regardless
of hardware capabilities.

crypto: atmel-aes - Fix 3-page memory leak in atmel_aes_buff_cleanup

2026-03-22T02:17:58+00:00

atmel_aes_buff_init() allocates 4 pages using __get_free_pages() with
ATMEL_AES_BUFFER_ORDER, but atmel_aes_buff_cleanup() frees only the
first page using free_page(), leaking the remaining 3 pages. Use
free_pages() with ATMEL_AES_BUFFER_ORDER to fix the memory leak.

crypto: atmel - Use unregister_{aeads,ahashes,skciphers}

2026-02-06T10:52:22+00:00

Replace multiple for loops with calls to crypto_unregister_aeads(),
crypto_unregister_ahashes(), and crypto_unregister_skciphers().

Remove the definition of atmel_tdes_unregister_algs() because it is
equivalent to calling crypto_unregister_skciphers() directly, and the
function parameter 'struct atmel_tdes_dev *' is unused anyway.

crypto: atmel - add CRYPTO_ALG_KERN_DRIVER_ONLY flag

2025-04-16T07:16:21+00:00

This patch introduces the CRYPTO_ALG_KERN_DRIVER_ONLY flag to the
atmel-aes, atmel-sha, and atmel-tdes drivers. This flag is set for
hardware accelerated ciphers accessible through a kernel driver only,
which is the case of these drivers.

crypto: drivers - Switch back to struct platform_driver::remove()

2024-10-19T00:44:30+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/crypto to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Simplify the code by replacing devm_clk_get() and clk_prepare() with
devm_clk_get_prepared(), which also avoids the call to clk_unprepare().

crypto: atmel-aes - Convert to platform remove callback returning void

2023-10-27T10:04:25+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
