[CRYPTO] api: Wake up all waiters when larval completes

2007-07-11T12:58:53Z

Right now when a larval matures or when it dies of an error we only wake up one waiter. This would cause other waiters to timeout unnecessarily. This patch changes it to use complete_all to wake up all waiters. Signed-off-by: Herbert Xu

[CRYPTO] api: Read module pointer before freeing algorithm

2007-05-19T04:51:00Z

The function crypto_mod_put first frees the algorithm and then drops the reference to its module. Unfortunately we read the module pointer which after freeing the algorithm and that pointer sits inside the object that we just freed. So this patch reads the module pointer out before we free the object. Thanks to Luca Tettamanti for reporting this. Signed-off-by: Herbert Xu

[CRYPTO] api: Allow multiple frontends per backend

2007-02-06T22:21:01Z

This patch adds support for multiple frontend types for each backend algorithm by passing the type and mask through to the backend type init function. Signed-off-by: Herbert Xu

[CRYPTO] api: Remove deprecated interface

[CRYPTO] api: Remove unused functions

2006-12-07T02:38:54Z

This patch removes the following no longer used functions: - api.c: crypto_alg_available() - digest.c: crypto_digest_init() - digest.c: crypto_digest_update() - digest.c: crypto_digest_final() - digest.c: crypto_digest_digest() Signed-off-by: Adrian Bunk Signed-off-by: Herbert Xu

[CRYPTO] api: fix crypto_alloc_base() return value

2006-10-11T12:29:51Z

This patch makes crypto_alloc_base() return proper return value. - If kzalloc() failure happens within __crypto_alloc_tfm(), crypto_alloc_base() returns NULL. But crypto_alloc_base() is supposed to return error code as pointer. So this patch makes it return -ENOMEM in that case. - crypto_alloc_base() is suppose to return -EINTR, if it is interrupted by signal. But it may not return -EINTR.

[CRYPTO] api: Add crypto_comp and crypto_has_*

2006-09-21T01:46:21Z

This patch adds the crypto_comp type to complete the compile-time checking conversion. The functions crypto_has_alg and crypto_has_cipher, etc. are also added to replace crypto_alg_available. Signed-off-by: Herbert Xu

[CRYPTO] api: Added crypto_type support

2006-09-21T01:41:51Z

This patch adds the crypto_type structure which will be used for all new crypto algorithm types, beginning with block ciphers. The primary purpose of this abstraction is to allow different crypto_type objects for crypto algorithms of the same type, in particular, there will be a different crypto_type objects for asynchronous algorithms.

[CRYPTO] api: Added crypto_alloc_base

2006-09-21T01:41:50Z

Up until now all crypto transforms have been of the same type, struct crypto_tfm, regardless of whether they are ciphers, digests, or other types. As a result of that, we check the types at run-time before each crypto operation. This is rather cumbersome. We could instead use different C types for each crypto type to ensure that the correct types are used at compile time. That is, we would have crypto_cipher/crypto_digest instead of just crypto_tfm. The appropriate type would then be required for the actual operations such as crypto_digest_digest. Now that we have the type/mask fields when looking up algorithms, it is easy to request for an algorithm of the precise type that the user wants. However, crypto_alloc_tfm currently does not expose these new attributes. This patch introduces the function crypto_alloc_base which will carry these new parameters. It will be renamed to crypto_alloc_tfm once all existing users have been converted. Signed-off-by: Herbert Xu

[CRYPTO] api: Added asynchronous flag

2006-09-21T01:41:49Z

This patch adds the asynchronous flag and changes all existing users to only look up algorithms that are synchronous. Signed-off-by: Herbert Xu
