2023-04-06crypto: ixp4xx - Move driver to drivers/crypto/intel/ixp4xxTom Zanussi1-1601/+0
With the growing number of Intel crypto drivers, it makes sense to group them all into a single drivers/crypto/intel/ directory. Create a separate drivers/crypto/intel/ixp4xx directory and move drivers/crypto/ixp4xx_crypto.c to it, along with a new Kconfig and Makefile to contain the config and make bits. Also add a COMPILE_TEST dependency to CRYPTO_DEV_IXP4XX so it can be more easily compile-tested.

2021-06-03crypto: ixp4xx - Add device tree supportLinus Walleij1-28/+79
This makes the IXP4xx driver probe from the device tree and retrieve the NPE and two queue manager handled used to process crypto from the device tree. As the crypto engine is topologically a part of the NPE hardware, we augment the NPE driver to spawn the crypto engine as a child. The platform data probe path is going away in due time, for now it is an isolated else clause.

2021-06-03crypto: ixp4xx - convert to platform driverArnd Bergmann1-24/+13
The ixp4xx_crypto driver traditionally registers a bare platform device without attaching it to a driver, and detects the hardware at module init time by reading an SoC specific hardware register. Change this to the conventional method of registering the platform device from the platform code itself when the device is present, turning the module_init/module_exit functions into probe/release driver callbacks. This enables compile-testing as well as potentially having ixp4xx coexist with other ARMv5 platforms in the same kernel in the future.

Testing ixp4xx_crypto lead to: alg: skcipher: ecb(des)-ixp4xx encryption overran dst buffer on test vector 0, cfg="two even aligned splits" The HW overwrites destination always when sg_nents() > 1. The problem seems that the HW always write areq->cryptlen bytes on the last SG. A comment in driver's code seems to give a clue that multiple SG was not planned "This was never tested by Intel for more than one dst buffer, I think". So let's add a fallback for this situation.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers1-1/+1
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

2020-01-09crypto: remove CRYPTO_TFM_RES_WEAK_KEYEric Biggers1-24/+4
The CRYPTO_TFM_RES_WEAK_KEY 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. There are also no tests that verify that all algorithms actually set (or don't set) it correctly. This is also the last remaining CRYPTO_TFM_RES_* flag, which means that it's the only thing still needing all the boilerplate code which propagates these flags around from child => parent tfms. And if someone ever needs to distinguish this error in the future (which is somewhat unlikely, as it's been unneeded for a long time), it would be much better to just define a new return value like -EKEYREJECTED. That would be much simpler, less error-prone, and easier to test. So just remove this flag. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2020-01-09crypto: remove CRYPTO_TFM_RES_BAD_KEY_LENEric Biggers1-3/+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: ixp4xx - switch to skcipher APIArd Biesheuvel1-120/+108
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.

CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it sounds like it is requesting a weak key. Actually, it is requesting that weak keys be forbidden (for algorithms that have the notion of "weak keys"; currently only DES and XTS do). Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which it can be easily confused. (This in fact happened in the UX500 driver, though just in some debugging messages.)

2019-01-08cross-tree: phase out dma_zalloc_coherent()Luis Chamberlain1-3/+3
We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig <hch@lst.de>
2018-12-23crypto: skcipher - remove remnants of internal IV generatorsEric Biggers1-5/+0
Remove dead code related to internal IV generators, which are no longer used since they've been replaced with the "seqiv" and "echainiv" templates. The removed code includes: - The "givcipher" (GIVCIPHER) algorithm type. No algorithms are registered with this type anymore, so it's unneeded. - The "const char *geniv" member of aead_alg, ablkcipher_alg, and blkcipher_alg. A few algorithms still set this, but it isn't used anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG. Just hardcode "<default>" or "<none>" in those cases. - The 'skcipher_givcrypt_request' structure, which is never used.

2018-03-30crypto: ixp4xx - don't leak pointers to authenc keysTudor-Dan Ambarus1-0/+2
In ixp4xx's aead_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. Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
