2021-01-03crypto: remove cipher routines from public crypto APIArd Biesheuvel1-0/+1
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.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers1-1/+2
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.

2020-09-25crypto: inside-secure - Reuse code in safexcel_hmac_alg_setkeyHerbert Xu1-14/+23
The code in the current implementation of safexcel_hmac_alg_setkey can be reused by safexcel_cipher. This patch does just that by renaming the previous safexcel_hmac_setkey to __safexcel_hmac_setkey. The now-shared safexcel_hmac_alg_setkey becomes safexcel_hmac_setkey and a new safexcel_hmac_alg_setkey has been added for use by ahash transforms. As a result safexcel_aead_setkey's stack frame has been reduced by about half in size, or about 512 bytes.

2020-01-09crypto: remove propagation of CRYPTO_TFM_RES_* flagsEric Biggers1-6/+0
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". That would be much simpler, less error-prone, and easier to test. So just remove CRYPTO_TFM_RES_MASK and all the unneeded logic that propagates these flags around.

2020-01-09crypto: remove CRYPTO_TFM_RES_BAD_KEY_LENEric Biggers1-12/+4
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.

This patch fixes another hang case on the EIP97 caused by sending invalidation tokens to the hardware when doing basic (3)DES ECB/CBC operations.

2019-12-20crypto: inside-secure - Fix Unable to fit even 1 command desc error w/ EIP97Pascal van Leeuwen1-2/+9
Due to the additions of support for modes like AES-CCM and AES-GCM, which require large command tokens, the size of the descriptor has grown such that it now does not fit into the descriptor cache of a standard EIP97 anymore. This means that the driver no longer works on the Marvell Armada 3700LP chip (as used on e.g. Espressobin) that it has always supported. Additionally, performance on EIP197's like Marvell A8K may also degrade due to being able to fit less descriptors in the on-chip cache. Putting these tokens into the descriptor was really a hack and not how the design was supposed to be used - resource allocation did not account for it. So what this patch does, is move the command token out of the descriptor. To avoid having to allocate buffers on the fly for these command tokens, they are stuffed in a "shadow ring", which is a circular buffer of fixed size blocks that runs in lock-step with the descriptor ring. i.e. there is one token block per descriptor. The descriptor ring itself is then pre- populated with the pointers to these token blocks so these do not need to be filled in when building the descriptors later.

This patch main goal is to improve driver performance by moving the crypto request from a list to a RDR ring shadow.

Doing this change eliminates the use of spinlock when accessing the descriptor ring and the need to dynamicaly allocate memory per crypto request. The crypto request is placed in the first RDR shadow descriptor only if there are enough descriptors, when the result handler is invoked, it fetches the first result descriptor from RDR shadow.

2018-07-09crypto: inside-secure - use precise compatiblesAntoine Tenart1-4/+4
At first we used two compatibles in the SafeXcel driver, named after the engine revision: eip97 and eip197. However this family of engines has more precise versions and in fact we're supporting the eip97ies and eip197b. More versions will be supported in the future, such as the eip197d, and we'll need to differentiate them. This patch fixes the compatibles used in the driver, to now use precise ones. The two historical compatibles are kept for backward compatibility. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
