2020-01-09crypto: remove CRYPTO_TFM_RES_BAD_KEY_LENEric Biggers1-1/+0
The CRYPTO_TFM_RES_BAD_KEY_LEN flag was apparently meant as a way to make the ->setkey() functions provide more information about errors. However, no one actually checks for this flag, which makes it pointless. Also, many algorithms fail to set this flag when given a bad length key. Reviewing just the generic implementations, this is the case for aes-fixed-time, cbcmac, echainiv, nhpoly1305, pcrypt, rfc3686, rfc4309, rfc7539, rfc7539esp, salsa20, seqiv, and xcbc. But there are probably many more in arch/*/crypto/ and drivers/crypto/. Some algorithms can even set this flag when the key is the correct length. For example, authenc and authencesn set it when the key payload is malformed in any way (not just a bad length), the atmel-sha and ccree drivers can set it if a memory allocation fails, and the chelsio driver sets it for bad auth tag lengths, not just bad key lengths. So even if someone actually wanted to start checking this flag (which seems unlikely, since it's been unused for a long time), there would be a lot of work needed to get it working correctly. But it would probably be much better to go back to the drawing board and just define different return values, like -EINVAL if the key is invalid for the algorithm vs. -EKEYREJECTED if the key was rejected by a policy like "no weak keys". That would be much simpler, less error-prone, and easier to test. So just remove this flag.

2019-11-17crypto: ccp - switch from ablkcipher to skcipherArd Biesheuvel1-92/+77
Commit 7a7ffe65c8c5 ("crypto: skcipher - Add top-level skcipher interface") dated 20 august 2015 introduced the new skcipher API which is supposed to replace both blkcipher and ablkcipher. While all consumers of the API have been converted long ago, some producers of the ablkcipher remain, forcing us to keep the ablkcipher support routines alive, along with the matching code to expose [a]blkciphers via the skcipher API. So switch this driver to the skcipher API, allowing us to finally drop the ablkcipher code in the near future.

2016-03-11crypto: ccp - CCP versioning supportGary R Hook1-1/+11
Future hardware may introduce new algorithms wherein the driver will need to manage resources for different versions of the cryptographic coprocessor. This precursor patch determines the version of the available device, and marks and registers algorithms accordingly. A structure is added which manages the version-specific data.
