Herbert Xu	973fb3fb50	crypto: skcipher - Add default key size helper ... While converting ecryptfs over to skcipher I found that it needs to pick a default key size if one isn't given. Rather than having it poke into the guts of the algorithm to get max_keysize, let's provide a helper that is meant to give a sane default (just in case we ever get an algorithm that has no maximum key size).

Herbert Xu	a1383cd86a	crypto: skcipher - Add crypto_skcipher_has_setkey ... This patch adds a way for skcipher users to determine whether a key is required by a transform. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2016-01-18 18:16:12 +08:00
Geliang Tang	ecdd6bed29	crypto: skcipher - blkcipher and ablkcipher should it be static ... Fixes the following sparse warnings: crypto/skcipher.c:94:5: warning: symbol 'crypto_init_skcipher_ops_blkcipher' was not declared. Should it be static? crypto/skcipher.c:185:5: warning: symbol 'crypto_init_skcipher_ops_ablkcipher' was not declared. Should it be static?

Herbert Xu	7a7ffe65c8	crypto: skcipher - Add top-level skcipher interface ... This patch introduces the crypto skcipher interface which aims to replace both blkcipher and ablkcipher. It's very similar to the existing ablkcipher interface. The main difference is the removal of the givcrypt interface. In order to make the transition easier for blkcipher users, there is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place a request on the stack for synchronous transforms.
