2008-12-25libcrc32c: Move implementation to crypto crc32cHerbert Xu
This patch swaps the role of libcrc32c and crc32c. Previously the implementation was in libcrc32c and crc32c was a wrapper. Now the code is in crc32c and libcrc32c just calls the crypto layer. The reason for the change is to tap into the algorithm selection capability of the crypto API so that optimised implementations such as the one utilising Intel's CRC32C instruction can be used where available. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-12-10crypto: api - Disallow cryptomgr as a module if algorithms are built-inHerbert Xu
If we have at least one algorithm built-in then it no longer makes sense to have the testing framework, and hence cryptomgr to be a module. It should be either on or off, i.e., built-in or disabled. This just happens to stop a potential runaway modprobe loop that seems to trigger on at least one distro. With fixes from Evgeniy Polyakov. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-08-29crypto: skcipher - Use RNG interface instead of get_random_bytesHerbert Xu
This patch makes the IV generators use the new RNG interface so that the user can pick an RNG other than the default get_random_bytes. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-08-29crypto: rng - RNG interface and implementationNeil Horman
This patch adds a random number generator interface as well as a cryptographic pseudo-random number generator based on AES. It is meant to be used in cases where a deterministic CPRNG is required. One of the first applications will be as an input in the IPsec IV generation process. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-08-29crypto: api - Add fips_enable flagNeil Horman
Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode. This patch allows us to set a kernel flag incating that we are running in a fips-compliant mode from boot up. It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.

2008-08-29crypto: crc32c - Use Intel CRC32 instructionAustin Zhang
From NHM processor onward, Intel processors can support hardware accelerated CRC32c algorithm with the new CRC32 instruction in SSE 4.2 instruction set. The patch detects the availability of the feature, and chooses the most proper way to calculate CRC32c checksum. Byte code instructions are used for compiler compatibility. No MMX / XMM registers is involved in the implementation.

2008-01-11[CRYPTO] blkcipher: Merge ablkcipher and blkcipher into one option/moduleHerbert Xu
With the impending addition of the givcipher type, both blkcipher and ablkcipher algorithms will use it to create givcipher objects. As such it no longer makes sense to split the system between ablkcipher and blkcipher. In particular, both ablkcipher.c and blkcipher.c would need to use the givcipher type which has to reside in ablkcipher.c since it shares much code with it. This patch merges the two Kconfig options as well as the modules into one. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2008-01-11[CRYPTO] sha256-generic: Extend sha256_generic.c to support SHA-224Jonathan Lynch
Resubmitting this patch which extends sha256_generic.c to support SHA-224 as described in FIPS 180-2 and RFC 3874. HMAC-SHA-224 as described in RFC4231 is then supported through the hmac interface. Patch includes test vectors for SHA-224 and HMAC-SHA-224. SHA-224 chould be chosen as a hash algorithm when 112 bits of security strength is required. Patch generated against the 2.6.24-rc1 kernel and tested against 2.6.24-rc1-git14 which includes fix for scatter gather implementation for HMAC.

2008-01-11[CRYPTO] ctr: Add CTR (Counter) block cipher modeJoy Latten
This patch implements CTR mode for IPsec. It is based off of RFC 3686. Please note: 1. CTR turns a block cipher into a stream cipher. Encryption is done in blocks, however the last block may be a partial block. A "counter block" is encrypted, creating a keystream that is xor'ed with the plaintext. The counter portion of the counter block is incremented after each block of plaintext is encrypted. Decryption is performed in same manner. 2. The CTR counterblock is composed of, nonce + IV + counter The size of the counterblock is equivalent to the blocksize of the cipher. sizeof(nonce) + sizeof(IV) + sizeof(counter) = blocksize The CTR template requires the name of the cipher algorithm, the sizeof the nonce, and the sizeof the iv. ctr(cipher,sizeof_nonce,sizeof_iv) So for example, ctr(aes,4,8) specifies the counterblock will be composed of 4 bytes from a nonce, 8 bytes from the iv, and 4 bytes for counter since aes has a blocksize of 16 bytes. 3. The counter portion of the counter block is stored in big endian for conformance to rfc 3686. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
