The run-time self-tests fail quite early, as soon as the input block size is larger than 64 bytes: alg: hash: Test 4 failed for sha1-sun4i-ss 00000000: b9 c9 1e 52 c0 26 d8 39 81 ff f2 3c 99 b1 27 b2 00000010: 30 d6 c9 85 One thing to notice is the value of the last word, which is the one expected (it can sometime be the last two words). The datasheet isn't very clear about when the digest is ready to retrieve and is seems the bit SS_DATA_END is cleared when the digest was computed *but* that doesn't mean the digest is ready to retrieve in the registers. A ndelay(1) is added before reading the computed digest to ensure it is available in the SS_MD[] registers. Signed-off-by:

The CRYPTO_ALG_KERN_DRIVER_ONLY flag is set for hardware accelerated ciphers accessible through a kernel driver only. This is the case for ciphers exposed by the sun4i-ss driver. This patch sets this flag. Signed-off-by:

Antoine Ténart authored
Update the sun4i-ss driver to use the skcipher API instead of the old ablkcipher one. It's a bit more tricky than s/ablkcipher/skcipher/, but still nothing special and the driver's logic stays the same. Signed-off-by:

When sending the last block of data to the engine, it should be padded so that the total length of the request can be given to the engine as the last 2 words of the last 64 bytes block. Simplify the calculation of this pad offset. Signed-off-by:

- Fixed bugs in example for shash and rng (added missing "*" and " *"). - Corrected pr_info() in calc_hash(). - Added example usage of calc_hash(). - No need for negate PTR_ERR to get error code, as crypto_alloc_rng already returns negative values like ERR_PTR(-ENOMEM). Fixed. Signed-off-by:

An updated patch that also handles the additional key length requirements for the AEAD algorithms. The max keysize is not 96. For SHA384/512 it's 128, and for the AEAD algorithms it's longer still. Extend the max keysize for the AEAD size for AES256 + HMAC(SHA512).

This patch removes the parent clock 'ethif' in bindings, since we don't need to control the parent of a clock in current clock framework. Moreover, the clocks are get by name in the driver, thus this change does not break backwards compatibility. Signed-off-by:

This patch removes redundant clock setting for 'clk_ethif', which is the parent of 'clk_cryp'. Hence, we just need to handle its child. Signed-off-by:

The test considers a party that already has a private-public key pair and a party that provides a NULL key. The kernel will generate the private-public key pair for the latter, computes the shared secret on both ends and verifies if it's the same. The explicit private-public key pair was copied from the previous test vector. Signed-off-by:

Add support for generating ecc private keys. Generation of ecc private keys is helpful in a user-space to kernel ecdh offload because the keys are not revealed to user-space. Private key generation is also helpful to implement forward secrecy. If the user provides a NULL ecc private key, the kernel will generate it and further use it for ecdh. Move ecdh's object files below drbg's. drbg must be present in the kernel at the time of calling. Signed-off-by:
