crypto: hash - Move ahash functions into crypto/hash.h

2008-07-10T12:35:18Z

All new crypto interfaces should go into individual files as much as possible in order to ensure that crypto.h does not collapse under its own weight. This patch moves the ahash code into crypto/hash.h and crypto/internal/hash.h respectively. Signed-off-by: Herbert Xu

crypto: hash - Added scatter list walking helper

2008-07-10T12:35:18Z

This patch adds the walking helpers for hash algorithms akin to those of block ciphers. This is a necessary step before we can reimplement existing hash algorithms using the new ahash interface. Signed-off-by: Herbert Xu

[CRYPTO] skcipher: Fix section mismatches

2008-03-08T12:29:43Z

The previous patch to move chainiv and eseqiv into blkcipher created a section mismatch for the chainiv exit function which was also called from __init. This patch removes the __exit marking on it. Signed-off-by: Herbert Xu

[CRYPTO] skcipher: Move chainiv/seqiv into crypto_blkcipher module

2008-02-23T03:12:06Z

For compatibility with dm-crypt initramfs setups it is useful to merge chainiv/seqiv into the crypto_blkcipher module. Since they're required by most algorithms anyway this is an acceptable trade-off. Signed-off-by: Herbert Xu

[CRYPTO] chainiv: Avoid lock spinning where possible

2008-01-10T21:16:55Z

This patch makes chainiv avoid spinning by postponing requests on lock contention if the user allows the use of asynchronous algorithms. If a synchronous algorithm is requested then we behave as before. This should improve IPsec performance on SMP when two CPUs attempt to transmit over the same SA. Currently one of them will spin doing nothing waiting for the other CPU to finish its encryption. This patch makes it postpone the request and get on with other work. If only one CPU is transmitting for a given SA, then we will process the request synchronously as before. Signed-off-by: Herbert Xu

[CRYPTO] null: Add null blkcipher algorithm

2008-01-10T21:16:53Z

This patch adds a null blkcipher algorithm called ecb(cipher_null) for backwards compatibility. Previously the null algorithm when used by IPsec copied the data byte by byte. This new algorithm optimises that to a straight memcpy which lets us better measure inherent overheads in our IPsec code. Signed-off-by: Herbert Xu

[CRYPTO] aead: Create default givcipher instances

2008-01-10T21:16:52Z

This patch makes crypto_alloc_aead always return algorithms that is capable of generating their own IVs through givencrypt and givdecrypt. All existing AEAD algorithms already do. New ones must either supply their own or specify a generic IV generator with the geniv field. Signed-off-by: Herbert Xu

[CRYPTO] aead: Add aead_geniv_alloc/aead_geniv_free

2008-01-10T21:16:51Z

This patch creates the infrastructure to help the construction of IV generator templates that wrap around AEAD algorithms by adding an IV generator to them. This is useful for AEAD algorithms with no built-in IV generator or to replace their built-in generator. Signed-off-by: Herbert Xu

[CRYPTO] skcipher: Create default givcipher instances

2008-01-10T21:16:46Z

This patch makes crypto_alloc_ablkcipher/crypto_grab_skcipher always return algorithms that are capable of generating their own IVs through givencrypt and givdecrypt. Each algorithm may specify its default IV generator through the geniv field. For algorithms that do not set the geniv field, the blkcipher layer will pick a default. Currently it's chainiv for synchronous algorithms and eseqiv for asynchronous algorithms. Note that if these wrappers do not work on an algorithm then that algorithm must specify its own geniv or it can't be used at all. Signed-off-by: Herbert Xu

[CRYPTO] skcipher: Added skcipher_givcrypt_complete

2008-01-10T21:16:45Z

This patch adds the helper skcipher_givcrypt_complete which should be called when an ablkcipher algorithm has completed a givcrypt request. Signed-off-by: Herbert Xu
