crypto: rng - Do not free default RNG when it becomes unused

2015-06-22T07:49:18Z

Currently we free the default RNG when its use count hits zero. This was OK when the IV generators would latch onto the RNG at instance creation time and keep it until the instance is torn down. Now that IV generators only keep the RNG reference during init time this scheme causes the default RNG to come and go at a high frequencey. This is highly undesirable as we want to keep a single RNG in use unless the admin wants it to be removed. This patch changes the scheme so that the system RNG once allocated is never removed unless a specifically requested. Signed-off-by: Herbert Xu

crypto: aead - Fix aead_instance struct size

2015-06-19T06:16:30Z

The struct aead_instance is meant to extend struct crypto_instance by incorporating the extra members of struct aead_alg. However, the current layout which is copied from shash/ahash does not specify the struct fully. In particular only aead_alg is present. For shash/ahash this works because users there add extra headroom to sizeof(struct crypto_instance) when allocating the instance. Unfortunately for aead, this bit was lost when the new aead_instance was added. Rather than fixing it like shash/ahash, this patch simply expands struct aead_instance to contain what is supposed to be there, i.e., adding struct crypto_instance. In order to not break existing AEAD users, this is done through an anonymous union. Signed-off-by: Herbert Xu

crypto: rsa - add a new rsa generic implementation

crypto: akcipher - add PKE API

2015-06-17T09:03:14Z

Add Public Key Encryption API. Signed-off-by: Tadeusz Struk Made CRYPTO_AKCIPHER invisible like other type config options. Signed-off-by: Herbert Xu

crypto: aead - Add multiple algorithm registration interface

2015-06-03T02:48:35Z

This patch adds the helpers that allow the registration and removal of multiple algorithms. Signed-off-by: Herbert Xu

crypto: aead - Ignore return value from crypto_unregister_alg

2015-06-03T02:48:34Z

No new code should be using the return value of crypto_unregister_alg as it will become void soon. Signed-off-by: Herbert Xu

crypto: aead - Add aead_alg_instance

2015-06-03T02:48:33Z

Now that type-safe init/exit functions exist, they often need to access the underlying aead_instance. So this patch adds the helper aead_alg_instance to access aead_instance from a crypto_aead object. Signed-off-by: Herbert Xu

crypto: aead - Add common IV generation code

2015-05-28T03:23:17Z

This patch adds some common IV generation code currently duplicated by seqiv and echainiv. For example, the setkey and setauthsize functions are completely identical. Signed-off-by: Herbert Xu

crypto: aead - Add crypto_aead_alg_ivsize/maxauthsize

2015-05-25T10:41:25Z

AEAD algorithm implementors need to figure out a given algorithm's IV size and maximum authentication size. During the transition this is difficult to do as an algorithm could be new style or old style. This patch creates two helpers to make this easier. Signed-off-by: Herbert Xu

crypto: seqiv - Add support for new AEAD interface

2015-05-22T03:25:56Z

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. Signed-off-by: Herbert Xu
