* crypto: s5p-sss - Constify pointed data (arguments and local variables)Krzysztof Kozlowski2018-03-091-14/+17
| | | | | | | | | | | | Improve the code (safety and readability) by indicating that data passed through pointer is not modified. This adds const keyword in many places, most notably: - the driver data (pointer to struct samsung_aes_variant), - scatterlist addresses written as value to device registers, - key and IV arrays.

* crypto: ccp - return an actual key size from RSA max_size callbackMaciej S. Szmigiero2018-03-021-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | rsa-pkcs1pad uses a value returned from a RSA implementation max_size callback as a size of an input buffer passed to the RSA implementation for encrypt and sign operations. CCP RSA implementation uses a hardware input buffer which size depends only on the current RSA key length, so it should return this key length in the max_size callback, too. This also matches what the kernel software RSA implementation does. Previously, the value returned from this callback was always the maximum RSA key size the CCP hardware supports. This resulted in this huge buffer being passed by rsa-pkcs1pad to CCP even for smaller key sizes and then in a buffer overflow when ccp_run_rsa_cmd() tried to copy this large input buffer into a RSA key length-sized hardware input buffer.

| | | | | | | | | | | | With ecb-cast5-avx, if a 128+ byte scatterlist element followed a shorter one, then the algorithm accidentally encrypted/decrypted only 8 bytes instead of the expected 128 bytes. Fix it by setting the encryption/decryption 'fn' correctly.
