crypto: starfive - remove unneeded crypto_engine_stop() call

2024-10-28T10:33:11Z

The explicit crypto_engine_stop() call is not needed, as it is already called internally by crypto_engine_exit(). Signed-off-by: Ovidiu Panait Signed-off-by: Herbert Xu

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

2024-10-19T00:44:30Z

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.

crypto: drivers - Drop sign/verify operations

2024-10-05T05:22:04Z

The drivers aspeed-acry.c, hpre_crypto.c and jh7110-rsa.c purport to implement sign/verify operations for raw (unpadded) "rsa". But there is no such thing as message digests generally need to be padded according to a predefined scheme (such as PSS or PKCS#1) to match the size of the usually much larger RSA keys. The bogus sign/verify operations defined by these drivers are never called but block removal of sign/verify from akcipher_alg. Drop them. Signed-off-by: Lukas Wunner Signed-off-by: Herbert Xu

crypto: starfive - Fix nent assignment in rsa dec

2024-07-06T00:20:00Z

Missing src scatterlist nent assignment in rsa decrypt function. Removing all unneeded assignment and use nents value from req->src instead. Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu

crypto: starfive - Align rsa input data to 32-bit

2024-07-06T00:20:00Z

Hardware expects RSA input plain/ciphertext to be 32-bit aligned. Set fixed length for preallocated buffer to the maximum supported keysize of the hardware and shift input text accordingly. Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu

crypto: starfive - Use fallback for unaligned dma access

2024-05-10T09:15:24Z

Dma address mapping fails on unaligned scatterlist offset. Use sw fallback for these cases. Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu

crypto: starfive - Do not free stack buffer

2024-05-10T09:15:24Z

RSA text data uses variable length buffer allocated in software stack. Calling kfree on it causes undefined behaviour in subsequent operations. Cc: #6.7+ Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu

crypto: starfive - Skip unneeded fallback allocation

2024-05-10T09:15:24Z

Skip sw fallback allocation if RSA module failed to get device handle. Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu

crypto: starfive - Skip dma setup for zeroed message

2024-05-10T09:15:24Z

Skip dma setup and mapping for AES driver if plaintext is empty. Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu

crypto: starfive - Use dma for aes requests

2024-04-02T02:49:38Z

Convert AES module to use dma for data transfers to reduce cpu load and compatible with future variants. Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu
