crypto: ccree - Correctly handle return of sg_nents_for_len

2026-01-11T14:21:29+00:00

[ Upstream commit 8700ce07c5c6bf27afa7b59a8d9cf58d783a7d5c ] Fix error handling in cc_map_hash_request_update where sg_nents_for_len return value was assigned to u32, converting negative errors to large positive values before passing to sg_copy_to_buffer. Check sg_nents_for_len return value and propagate errors before assigning to areq_ctx->in_nents.

crypto: drivers - Explicitly include correct DT includes

2023-08-23T03:04:23+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

crypto: ccree - Use devm_platform_get_and_ioremap_resource()

2023-03-14T09:06:42+00:00

Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does. Signed-off-by: Yang Li Acked-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: xts - drop xts_check_key()

2023-01-06T09:15:47+00:00

xts_check_key() is obsoleted by xts_verify_key(). Over time XTS crypto drivers adopted the newer xts_verify_key() variant, but xts_check_key() is still used by a number of drivers. Switch drivers to use the newer xts_verify_key() and make a couple of cleanups. This allows us to drop xts_check_key() completely and avoid redundancy.

crypto: ccree - Set DMA alignment explicitly

2022-12-09T10:45:00+00:00

This driver has been implicitly relying on kmalloc alignment to be sufficient for DMA. This may no longer be the case with upcoming arm64 changes. This patch changes it to explicitly request DMA alignment from the Crypto API. Signed-off-by: Herbert Xu

crypto: ccree - Make cc_debugfs_global_fini() available for module init function

2022-11-22T10:12:55+00:00

ccree_init() calls cc_debugfs_global_fini(), the former is an init function and the latter an exit function though. A modular build emits: WARNING: modpost: drivers/crypto/ccree/ccree.o: section mismatch in reference: init_module (section: .init.text) -> cc_debugfs_global_fini (section: .exit.text) (with CONFIG_DEBUG_SECTION_MISMATCH=y).

crypto: ccree - Remove debugfs when platform_driver_register failed

crypto: ccree - Remove a useless dma_supported() call

2022-07-29T10:29:16+00:00

There is no point in calling dma_supported() before calling dma_set_coherent_mask(). This function already calls dma_supported() and returns an error (-EIO) if it fails. So remove the superfluous dma_supported() call. Moreover, setting a larger DMA mask will never fail when setting a smaller one will succeed, so the whole "while" loop can be removed as well. (see [1]) While at it, fix the name of the function reported in a dev_err().
