2021-12-24crypto: ux500 - Use platform_get_irq() to get the interruptLad Prabhakar2-19/+9
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq() so that interrupt mapping is created on demand. While at it also store the IRQ number in struct cryp_device_data so that we don't have to call platform_get_irq() frequently.

2021-03-26crypto: ux500 - fix incorrect kernel-doc comment syntaxAditya Srivastava4-12/+12
The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. There are certain files in drivers/crypto/ux500, which follow this syntax, but the content inside does not comply with kernel-doc. Such lines were probably not meant for kernel-doc parsing, but are parsed due to the presence of kernel-doc like comment syntax(i.e, '/**'), which causes unexpected warnings from kernel-doc. E.g., presence of kernel-doc like comment in the header lines for drivers/crypto/ux500/cryp/cryp.h at header causes this warning: "warning: expecting prototype for ST(). Prototype was for _CRYP_H_() instead" Similarly for other files too. Provide a simple fix by replacing such occurrences with general comment format, i.e. '/*', to prevent kernel-doc from parsing it.

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.

Once the crypto hash walk is started by crypto_hash_walk_first() returning non-zero, crypto_hash_walk_done() must be called to unmap any memory which was mapped by *_walk_first(). Ensure crypto_hash_walk_done() is called properly by: 1) Re-arranging the check for device data to be prior to calling *_walk_first() 2) on error call crypto_hash_walk_done() with an error code to allow the hash walk code to clean up.

The header file algapi.h includes skbuff.h unnecessarily since all we need is a forward declaration for struct sk_buff. This patch removes that inclusion.

2020-07-09crypto: ux500/hash - Add namespacing to hash_init()Lee Jones1-9/+9
A recent change to the Regulator consumer API (which this driver utilises) add prototypes for the some suspend functions. These functions require including header file include/linux/suspend.h. The following tree of includes affecting this driver will be present: In file included from include/linux/elevator.h:6, from include/linux/blkdev.h:288, from include/linux/blk-cgroup.h:23, from include/linux/writeback.h:14, from include/linux/memcontrol.h:22, from include/linux/swap.h:9, from include/linux/suspend.h:5, from include/linux/regulator/consumer.h:35, from drivers/crypto/ux500/hash/hash_core.c:28: include/linux/elevator.h pulls in include/linux/hashtable.h which contains its own version of hash_init(). This confuses the build system and results in the following error (amongst others): drivers/crypto/ux500/hash/hash_core.c:1362:19: error: passing argument 1 of '__hash_init' from incompatible pointer type [-Werror=incompatible-pointer-types] 1362 | return hash_init(req); Fix this by namespacing the local hash_init() such that the source of confusion is removed.

2020-01-09crypto: remove CRYPTO_TFM_RES_BAD_KEY_LENEric Biggers1-2/+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.

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.

2019-01-25crypto: clarify name of WEAK_KEY request flagEric Biggers1-9/+11
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.) Therefore, make the intent clear by renaming it to CRYPTO_TFM_REQ_FORBID_WEAK_KEYS. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This is only for GNSS receivers, but you have to start somewhere, and this is great to see.

2018-07-08crypto: ahash - remove useless setting of cra_typeEric Biggers1-3/+0
Some ahash algorithms set .cra_type = &crypto_ahash_type. But this is redundant with the C structure type ('struct ahash_alg'), and crypto_register_ahash() already sets the .cra_type automatically.

2018-02-15crypto: ux500/hash - Add empty export and importKamil Konieczny1-0/+18
Crypto framework requires export/import in async hash. If driver do not implement them, wrapper functions in framework will be used, and it will cause error during ahash alg registration (unless one disables crypto internal tests). To make change in framework and expose this requirement, I will remove wrappers from crypto/ahash.c , but this can broke code which depends on them. Add empty hash export and import, with the same behaviour as in framework and expose this directly in driver. This can also prevent OOPS when config option in Cryptographic API 'Disable run-time self tests' will be enabled.

I have not found a good reason for doing this here, other than a misguided attempt to produce more readable assembly output. Also, the driver is only used in obsolete hardware that almost certainly nobody will spend time debugging any more. This just removes the -O0 flag from the compiler options.
