crypto: authenc - don't leak pointers to authenc keys

2018-04-20T16:58:30+00:00

In crypto_authenc_setkey we save pointers to the authenc keys in
a local variable of type struct crypto_authenc_keys and we don't
zeroize it after use. Fix this and don't leak pointers to the
authenc keys.

crypto: null - Get rid of crypto_{get,put}_default_null_skcipher2()

2017-12-22T08:29:08+00:00

Since commit 499a66e6b689 ("crypto: null - Remove default null
blkcipher"), crypto_get_default_null_skcipher2() and
crypto_put_default_null_skcipher2() are the same as their non-2
equivalents.  So switch callers of the "2" versions over to the original
versions and remove the "2" versions.

crypto: skcipher - Get rid of crypto_spawn_skcipher2()

2016-11-01T00:37:17+00:00

Since commit 3a01d0ee2b99 ("crypto: skcipher - Remove top-level
givcipher interface"), crypto_spawn_skcipher2() and
crypto_spawn_skcipher() are equivalent.  So switch callers of
crypto_spawn_skcipher2() to crypto_spawn_skcipher() and remove it.

crypto: skcipher - Get rid of crypto_grab_skcipher2()

2016-11-01T00:37:16+00:00

Since commit 3a01d0ee2b99 ("crypto: skcipher - Remove top-level
givcipher interface"), crypto_grab_skcipher2() and
crypto_grab_skcipher() are equivalent.  So switch callers of
crypto_grab_skcipher2() to crypto_grab_skcipher() and remove it.

crypto: authenc - Use skcipher

2016-07-18T09:35:38+00:00

This patch converts authenc to use the new skcipher interface as
opposed to ablkcipher.

It also fixes a little bug where if a sync version of authenc
is requested we may still end up using an async ahash.  This should
have no effect as none of the authenc users can request for a
sync authenc.

crypto: authenc - Consider ahash ASYNC bit

2016-07-01T15:45:02+00:00

As it is, if you get an async ahash with a sync skcipher you'll
end up with a sync authenc, which is wrong.

This patch fixes it by considering the ASYNC bit from ahash as
well.

It also fixes a little bug where if a sync version of authenc
is requested we may still end up using an async ahash.

Neither of them should have any effect as none of the authenc
users can request for a sync authenc.

crypto: authenc - Use crypto_aead_set_reqsize helper

2015-05-13T02:31:37+00:00

This patch uses the crypto_aead_set_reqsize helper to avoid directly
touching the internals of aead.
