2016-08-09crypto: powerpc - CRYPT_CRC32C_VPMSUM should depend on ALTIVECMichael Ellerman1-1/+1
The optimised crc32c implementation depends on VMX (aka. Altivec) instructions, so the kernel must be built with Altivec support in order for the crc32c code to build.

2016-07-05crypto: powerpc - Add POWER8 optimised crc32cAnton Blanchard1-0/+11
Use the vector polynomial multiply-sum instructions in POWER8 to speed up crc32c. This is just over 41x faster than the slice-by-8 method that it replaces. Measurements on a 4.1 GHz POWER8 show it sustaining 52 GiB/sec. A simple btrfs write performance test: dd if=/dev/zero of=/mnt/tmpfile bs=1M count=4096 sync is over 3.7x faster.

Add key-agreement protocol primitives (kpp) API which allows to implement primitives required by protocols such as DH and ECDH. The API is composed mainly by the following functions * set_secret() - It allows the user to set his secret, also referred to as his private key, along with the parameters known to both parties involved in the key-agreement session. * generate_public_key() - It generates the public key to be sent to the other counterpart involved in the key-agreement session. The function has to be called after set_params() and set_secret() * generate_secret() - It generates the shared secret for the session Other functions such as init() and exit() are provided for allowing cryptographic hardware to be inizialized properly before use Signed-off-by: Salvatore Benedetto <salvatore.benedetto@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2016-06-15crypto: drbg - use CTR AES instead of ECB AESStephan Mueller1-0/+1
The CTR DRBG derives its random data from the CTR that is encrypted with AES. This patch now changes the CTR DRBG implementation such that the CTR AES mode is employed. This allows the use of steamlined CTR AES implementation such as ctr-aes-aesni. Unfortunately there are the following subtile changes we need to apply when using the CTR AES mode: - the CTR mode increments the counter after the cipher operation, but the CTR DRBG requires the increment before the cipher op. Hence, the crypto_inc is applied to the counter (drbg->V) once it is recalculated. - the CTR mode wants to encrypt data, but the CTR DRBG is interested in the encrypted counter only. The full CTR mode is the XOR of the encrypted counter with the plaintext data. To access the encrypted counter, the patch uses a NULL data vector as plaintext to be "encrypted".

2016-02-01crypto: engine - Introduce the block request crypto engine frameworkBaolin Wang1-0/+3
Now block cipher engines need to implement and maintain their own queue/thread for processing requests, moreover currently helpers provided for only the queue itself (in crypto_enqueue_request() and crypto_dequeue_request()) but they don't help with the mechanics of driving the hardware (things like running the request immediately, DMA map it or providing a thread to process the queue in) even though a lot of that code really shouldn't vary that much from device to device. Thus this patch provides a mechanism for pushing requests to the hardware as it becomes free that drivers could use. And this framework is patterned on the SPI code and has worked out well there.

When building the jitterentropy driver by itself, we get a link error when CRYPTO_RNG is not enabled as well: crypto/built-in.o: In function `jent_mod_init': jitterentropy-kcapi.c:(.init.text+0x98): undefined reference to `crypto_register_rng' crypto/built-in.o: In function `jent_mod_exit': jitterentropy-kcapi.c:(.exit.text+0x60): undefined reference to `crypto_unregister_rng' This adds a 'select CRYPTO_RNG' to CRYPTO_JITTERENTROPY to ensure the API is always there when it's used, not just when DRBG is also enabled. CRYPTO_DRBG would set it implicitly through CRYPTO_JITTERENTROPY now, but this leaves it in place to make it explicit what the driver does.

2015-07-17crypto: poly1305 - Add a SSE2 SIMD variant for x86_64Martin Willi1-0/+12
Implements an x86_64 assembler driver for the Poly1305 authenticator. This single block variant holds the 130-bit integer in 5 32-bit words, but uses SSE to do two multiplications/additions in parallel. When calling updates with small blocks, the overhead for kernel_fpu_begin/ kernel_fpu_end() negates the perfmance gain. We therefore use the poly1305-generic fallback for small updates.

ChaCha20 is a high speed 256-bit key size stream cipher algorithm designed by Daniel J. Bernstein. It is further specified in RFC7539 for use in IETF protocols as a building block for the ChaCha20-Poly1305 AEAD. This is a portable C implementation without any architecture specific optimizations. It uses a 16-byte IV, which includes the 12-byte ChaCha20 nonce prepended by the initial block counter. Some algorithms require an explicit counter value, for example the mentioned AEAD construction.

2015-05-27crypto: jitterentropy - add jitterentropy RNGStephan Mueller1-0/+10
The CPU Jitter RNG provides a source of good entropy by collecting CPU executing time jitter. The entropy in the CPU execution time jitter is magnified by the CPU Jitter Random Number Generator. The CPU Jitter Random Number Generator uses the CPU execution timing jitter to generate a bit stream which complies with different statistical measurements that determine the bit stream is random. The CPU Jitter Random Number Generator delivers entropy which follows information theoretical requirements. Based on these studies and the implementation, the caller can assume that one bit of data extracted from the CPU Jitter Random Number Generator holds one bit of entropy. The CPU Jitter Random Number Generator provides a decentralized source of entropy, i.e. every caller can operate on a private state of the entropy pool. The RNG does not have any dependencies on any other service in the kernel. The RNG only needs a high-resolution time stamp. Further design details, the cryptographic assessment and large array of test results are documented at http://www.chronox.de/jent.html.

2015-05-26crypto: algif_aead - Disable AEAD user-space for nowHerbert Xu1-9/+0
The newly added AEAD user-space isn't quite ready for prime time just yet. In particular it is conflicting with the AEAD single SG list interface change so this patch disables it now. Once the SG list stuff is completely done we can then renable this interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: echainiv - Add encrypted chain IV generatorHerbert Xu1-0/+10
This patch adds a new AEAD IV generator echainiv. It is intended to replace the existing skcipher IV generator eseqiv. If the underlying AEAD algorithm is using the old AEAD interface, then echainiv will simply use its IV generator. Otherwise, echainiv will encrypt a counter just like eseqiv but it'll first xor it against a previously stored IV similar to chainiv. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: seqiv - Add support for new AEAD interfaceHerbert Xu1-0/+1
This patch converts the seqiv IV generator to work with the new AEAD interface where IV generators are just normal AEAD algorithms. Full backwards compatibility is paramount at this point since no users have yet switched over to the new interface. Nor can they switch to the new interface until IV generation is fully supported by it. So this means we are adding two versions of seqiv alongside the existing one. The first one is the one that will be used when the underlying AEAD algorithm has switched over to the new AEAD interface. The second one handles the current case where the underlying AEAD algorithm still uses the old interface. Both versions export themselves through the new AEAD interface.

2015-05-11crypto: 842 - change 842 alg to use softwareDan Streetman1-4/+3
Change the crypto 842 compression alg to use the software 842 compression and decompression library. Add the crypto driver_name as "842-generic". Remove the fallback to LZO compression. Previously, this crypto compression alg attemped 842 compression using PowerPC hardware, and fell back to LZO compression and decompression if the 842 PowerPC hardware was unavailable or failed. This should not fall back to any other compression method, however; users of this crypto compression alg can fallback if desired, and transparent fallback tricks callers into thinking they are getting 842 compression when they actually get LZO compression - the failure of the 842 hardware should not be transparent to the caller. The crypto compression alg for a hardware device also should not be located in crypto/ so this is now a software-only implementation that uses the 842 software compression/decompression library.
