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

2015-06-22T07:49:18+00:00

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: rng - Remove old low-level rng interface

2015-04-22T01:30:20+00:00

Now that all rng implementations have switched over to the new interface, we can remove the old low-level interface. Signed-off-by: Herbert Xu

crypto: rng - Add multiple algorithm registration interface

2015-04-22T01:30:16+00:00

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

crypto: rng - Add crypto_rng_set_entropy

2015-04-22T01:30:15+00:00

This patch adds the function crypto_rng_set_entropy. It is only meant to be used by testmgr when testing RNG implementations by providing fixed entropy data in order to verify test vectors. Signed-off-by: Herbert Xu

crypto: rng - Convert low-level crypto_rng to new style

2015-04-22T01:30:14+00:00

This patch converts the low-level crypto_rng interface to the "new" style. This allows existing implementations to be converted over one- by-one. Once that is complete we can then remove the old rng interface. Signed-off-by: Herbert Xu

crypto: rng - RNG interface and implementation

2008-08-29T05:50:04+00:00

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 Signed-off-by: Herbert Xu
