2011-11-02crypto: user - Fix rwsem leak in crypto_userJonathan Corbet
The list_empty case in crypto_alg_match() will return without calling up_read() on crypto_alg_sem. We could do the "goto out" routine, but the function will clearly do the right thing with that test simply removed.

2011-10-21crypto: user - Initialise match in crypto_alg_matchHerbert Xu
We need to default match to 0 as otherwise it may lead to a false positive. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2011-10-21crypto: Add a report function pointer to crypto_typeSteffen Klassert
We add a report function pointer to struct crypto_type. This function pointer is used from the crypto userspace configuration API to report crypto algorithms to userspace. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2011-10-21crypto: Add userspace configuration APISteffen Klassert
This patch adds a basic userspace configuration API for the crypto layer. With this it is possible to instantiate, remove and to show crypto algorithms from userspace. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
