crypto: bfin_crc - remove blackfin CRC driver

2018-03-23T15:48:37+00:00

The blackfin architecture is getting removed, so this driver won't be used any more. Signed-off-by: Arnd Bergmann Signed-off-by: Herbert Xu

crypto: bfin_crc - Delete an error message for a failed memory allocation in bfin_crypto_crc_probe()

2018-02-22T14:16:56+00:00

Omit an extra message for a memory allocation failure in this function. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Herbert Xu

crypto: bfin_crc - Add empty hash export and import

2018-02-15T15:23:46+00:00

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. Signed-off-by: Kamil Konieczny Signed-off-by: Herbert Xu

crypto: hash - annotate algorithms taking optional key

2018-01-12T12:03:35+00:00

We need to consistently enforce that keyed hashes cannot be used without setting the key. To do this we need a reliable way to determine whether a given hash algorithm is keyed or not. AF_ALG currently does this by checking for the presence of a ->setkey() method. However, this is actually slightly broken because the CRC-32 algorithms implement ->setkey() but can also be used without a key. (The CRC-32 "key" is not actually a cryptographic key but rather represents the initial state. If not overridden, then a default initial state is used.) Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which indicates that the algorithm has a ->setkey() method, but it is not required to be called. Then set it on all the CRC-32 algorithms. The same also applies to the Adler-32 implementation in Lustre. Also, the cryptd and mcryptd templates have to pass through the flag from their underlying algorithm. Cc: stable@vger.kernel.org Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: bfin_crc - Fix format printing warning

2016-12-27T09:50:51+00:00

bfin_crc.c print some u32 as unsigned long ans so gcc complains about it. This patch remove the long print qualifier. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: bfin_crc - Simplify use of devm_ioremap_resource

2016-07-05T15:05:24+00:00

Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. The Coccinelle semantic patch that makes this change is as follows: // @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // Signed-off-by: Amitoj Kaur Chawla Signed-off-by: Herbert Xu

crypto: bfin_crc - replace sg_count by sg_nents

2015-09-21T15:05:53+00:00

The sg_count function in bfin_crc.c is the same function as sg_nents. Remove the duplicate code and use sg_nents() instead. Signed-off-by: LABBE Corentin Signed-off-by: Herbert Xu

crypto: replace scatterwalk_sg_next with sg_next

2015-01-26T00:34:22+00:00

Modify crypto drivers to use the generic SG helper since both of them are equivalent and the one from crypto is redundant. See also: 468577abe37ff7b453a9ac613e0ea155349203ae reverted in b2ab4a57b018aafbba35bff088218f5cc3d2142e Signed-off-by: Cristian Stoica Signed-off-by: Herbert Xu
