Remove the unused CFB/OFB implementation. Signed-off-by: Herbert Xu

crypto: safexcel - Add error handling for dma_map_sg() calls

2023-12-08T03:59:44Z

Macro dma_map_sg() may return 0 on error. This patch enables checks in case of the macro failure and ensures unmapping of previously mapped buffers with dma_unmap_sg(). Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE. Fixes: 49186a7d9e46 ("crypto: inside_secure - Avoid dma map if size is zero") Signed-off-by: Nikita Zhandarovich Reviewed-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: safexcel - Use crypto_wait_req

2023-02-10T09:20:19Z

This patch replaces the custom crypto completion function with crypto_req_done. Signed-off-by: Herbert Xu

crypto: inside-secure - Replace generic aes with libaes

2022-09-24T08:14:43Z

Commit 363a90c2d517 ("crypto: safexcel/aes - switch to library version of key expansion routine") removed CRYPTO_AES in the config. However, some portions of codes still rely on generic AES cipher (e.g. refer to safexcel_aead_gcm_cra_init(), safexcel_xcbcmac_cra_init()). This causes transform allocation failure for those algos, if CRYPTO_AES is not manually enabled. To resolve that, we replace all existing AES cipher dependent codes with their AES library counterpart.

crypto: inside_secure - Avoid dma map if size is zero

2022-09-24T08:14:42Z

From commit d03c54419274 ("dma-mapping: disallow .map_sg operations from returning zero on error"), dma_map_sg() produces warning if size is 0. This results in visible warnings if crypto length is zero. To avoid that, we avoid calling dma_map_sg if size is zero. Signed-off-by: Peter Harliman Liem Signed-off-by: Herbert Xu

crypto: sha - split sha.h into sha1.h and sha2.h

2020-11-20T03:45:33Z

Currently contains declarations for both SHA-1 and SHA-2, and contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split into two headers and , and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

crypto: inside-secure - Reuse code in safexcel_hmac_alg_setkey

2020-09-25T07:48:13Z

The code in the current implementation of safexcel_hmac_alg_setkey can be reused by safexcel_cipher. This patch does just that by renaming the previous safexcel_hmac_setkey to __safexcel_hmac_setkey. The now-shared safexcel_hmac_alg_setkey becomes safexcel_hmac_setkey and a new safexcel_hmac_alg_setkey has been added for use by ahash transforms. As a result safexcel_aead_setkey's stack frame has been reduced by about half in size, or about 512 bytes. Reported-by: kernel test robot Signed-off-by: Herbert Xu

crypto: inside-secure - Move ipad/opad into safexcel_context

2020-09-25T07:48:13Z

As both safexcel_ahash_ctx and safexcel_cipher_ctx contain ipad and opad buffers this patch moves them into the common struct safexcel_context. It also adds a union so that they can be accessed in the appropriate endian without crazy casts. Signed-off-by: Herbert Xu

crypto: inside-secure - Move priv pointer into safexcel_context

2020-09-25T07:48:12Z

This patch moves the priv pointer into struct safexcel_context because both structs that extend safexcel_context have that pointer as well. Signed-off-by: Herbert Xu
