crypto: remove cipher routines from public crypto API The cipher routines in the crypto API are mostly intended for templates implementing skcipher modes generically in software, and shouldn't be used outside of the crypto subsystem. So move the prototypes and all related definitions to a new header file under include/crypto/internal. Also, let's use the new module namespace feature to move the symbol exports into a new namespace CRYPTO_INTERNAL.

crypto: geode-aes - convert to skcipher API and make thread-safe The geode AES driver is heavily broken because it stores per-request state in the transform context. So it will crash or produce the wrong result if used by any of the many places in the kernel that issue concurrent requests for the same transform object. This driver is also implemented using the deprecated blkcipher API, which makes it difficult to fix, and puts it among the drivers preventing that API from being removed. Convert this driver to use the skcipher API, and change it to not store per-request state in the transform context.

crypto: geode-aes - convert to skcipher API and make thread-safe The geode AES driver is heavily broken because it stores per-request state in the transform context. So it will crash or produce the wrong result if used by any of the many places in the kernel that issue concurrent requests for the same transform object. This driver is also implemented using the deprecated blkcipher API, which makes it difficult to fix, and puts it among the drivers preventing that API from being removed. Convert this driver to use the skcipher API, and change it to not store per-request state in the transform context.

crypto: remove CRYPTO_TFM_RES_BAD_KEY_LEN 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.

crypto: remove propagation of CRYPTO_TFM_RES_* flags The CRYPTO_TFM_RES_* flags were apparently meant as a way to make the ->setkey() functions provide more information about errors. But these flags weren't actually being used or tested, and in many cases they weren't being set correctly anyway. So they've now been removed. Also, if someone ever actually needs to start better distinguishing ->setkey() errors (which is somewhat unlikely, as this has been unneeded for a long time), we'd be much better off just defining 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".

crypto: geode-aes - convert to skcipher API and make thread-safe The geode AES driver is heavily broken because it stores per-request state in the transform context. So it will crash or produce the wrong result if used by any of the many places in the kernel that issue concurrent requests for the same transform object. This driver is also implemented using the deprecated blkcipher API, which makes it difficult to fix, and puts it among the drivers preventing that API from being removed. Convert this driver to use the skcipher API, and change it to not store per-request state in the transform context.

crypto: geode-aes - switch to skcipher for cbc(aes) fallback Commit 79c65d179a40e145 ("crypto: cbc - Convert to skcipher") updated the generic CBC template wrapper from a blkcipher to a skcipher algo, to get away from the deprecated blkcipher interface. However, as a side effect, drivers that instantiate CBC transforms using the blkcipher as a fallback no longer work, since skciphers can wrap blkciphers but not the other way around. This broke the geode-aes driver. So let's fix it by moving to the sync skcipher interface when allocating the fallback. At the same time, align with the generic API for ECB and CBC by rejecting inputs that are not a multiple of the AES block size.

crypto: geode-aes - convert to skcipher API and make thread-safe The geode AES driver is heavily broken because it stores per-request state in the transform context. So it will crash or produce the wrong result if used by any of the many places in the kernel that issue concurrent requests for the same transform object. This driver is also implemented using the deprecated blkcipher API, which makes it difficult to fix, and puts it among the drivers preventing that API from being removed. Convert this driver to use the skcipher API, and change it to not store per-request state in the transform context.

Drivers: crypto: remove __dev* attributes. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
