| * | | crypto: ctr - Use skcipher in rfc3686Herbert Xu2016-07-181-89/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts rfc3686 to use the new skcipher interface as opposed to ablkcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: authencesn - Use skcipherHerbert Xu2016-07-181-50/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts authencesn to use the new skcipher interface as opposed to ablkcipher. It also fixes a little bug where if a sync version of authencesn is requested we may still end up using an async ahash. This should have no effect as none of the authencesn users can request for a sync authencesn. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * | | crypto: aead - Add chunk sizeHerbert Xu2016-07-181-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a chunk size parameter to aead algorithms, just like the chunk size for skcipher algorithms. However, unlike skcipher we do not currently export this to AEAD users. It is only meant to be used by AEAD implementors for now. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: null - Add new default null skcipherHerbert Xu2016-07-181-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current the default null skcipher is actually a crypto_blkcipher. This patch creates a synchronous crypto_skcipher version of the null cipher which unfortunately has to settle for the name skcipher2. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | crypto: skcipher - Add low-level skcipher interfaceHerbert Xu2016-07-181-7/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows skcipher algorithms and instances to be created and registered with the crypto API. They are accessible through the top-level skcipher interface, along with ablkcipher/blkcipher algorithms and instances. This patch also introduces a new parameter called chunk size which is meant for ciphers such as CTR and CTS which ostensibly can handle arbitrary lengths, but still behave like block ciphers in that you can only process a partial block at the very end. For these ciphers the block size will continue to be set to 1 as it is now while the chunk size will be set to the underlying block size. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the software RSA implementation now produces fixed-length output, we need to eliminate leading zeros in the calling code instead.

| * | | crypto: rsa-pkcs1pad - Avoid copying output when possibleHerbert Xu2016-07-011-67/+45Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the vast majority of cases (2^-32 on 32-bit and 2^-64 on 64-bit) cases, the result from encryption/signing will require no padding. This patch makes these two operations write their output directly to the final destination. Only in the exceedingly rare cases where fixup is needed to we copy it out and back to add the leading zeroes. This patch also makes use of the crypto_akcipher_set_crypt API instead of writing the akcipher request directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only user of rsa-pkcs1pad always uses the hash so there is no reason to support the case of not having a hash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every implementation of RSA that we have naturally generates output with leading zeroes. The one and only user of RSA, pkcs1pad wants to have those leading zeroes in place, in fact because they are currently absent it has to write those zeroes itself. So we shouldn't be stripping leading zeroes in the first place. In fact this patch makes rsa-generic produce output with fixed length so that pkcs1pad does not need to do any extra work. This patch also changes DH to use the new interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

It is now replaced with ktime_get_ns. The Jitter RNG uses the time stamp to measure the execution time of a given code path and tries to detect variations in the execution time. Therefore, the only requirement the Jitter RNG has, is a sufficient high resolution to detect these variations. The change was tested on x86 to show an identical behavior as RDTSC. The used test code simply measures the execution time of the heart of the RNG: jent_get_nstime(&time); jent_memaccess(ec, min); jent_fold_time(NULL, time, &folded, min); jent_get_nstime(&time2); return ((time2 - time)); Signed-off-by: Stephan Mueller <smueller@chronox.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it is if you ask for a sync gcm you may actually end up with an async one because it does not filter out async implementations of ghash. This patch fixes this by adding the necessary filter when looking for ghash. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Update the RSA software implementation so that it does the MPI conversion on top. Signed-off-by: Tudor Ambarus <tudor-dan.ambarus@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CTR DRBG update function performs a full CTR AES operation including the XOR with "plaintext" data. Hence, remove the XOR from the code and use the CTR mode to do the XOR. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
