2019-05-09crypto: caam - fix DKP detection logicHerbert Xu
The detection for DKP (Derived Key Protocol) relied on the value of the setkey function. This was broken by the recent change which added des3_aead_setkey. This patch fixes this by introducing a new flag for DKP and setting that where needed.

2019-05-03crypto: crypto4xx - fix cfb and ofb "overran dst buffer" issuesChristian Lamparter
Currently, crypto4xx CFB and OFB AES ciphers are failing testmgr's test vectors. |cfb-aes-ppc4xx encryption overran dst buffer on test vector 3, cfg="in-place" |ofb-aes-ppc4xx encryption overran dst buffer on test vector 1, cfg="in-place" This is because of a very subtile "bug" in the hardware that gets indirectly mentioned in 18.1.3.5 Encryption/Decryption of the hardware spec: the OFB and CFB modes for AES are listed there as operation modes for >>> "Block ciphers" <<<. Which kind of makes sense, but we would like them to be considered as stream ciphers just like the CTR mode. To workaround this issue and stop the hardware from causing "overran dst buffer" on crypttexts that are not a multiple of 16 (AES_BLOCK_SIZE), we force the driver to use the scatter buffers as the go-between. As a bonus this patch also kills redundant pd_uinfo->num_gd and pd_uinfo->num_sd setters since the value has already been set before.

2019-05-03crypto: crypto4xx - fix ctr-aes missing output IVChristian Lamparter
Commit 8efd972ef96a ("crypto: testmgr - support checking skcipher output IV") caused the crypto4xx driver to produce the following error: | ctr-aes-ppc4xx encryption test failed (wrong output IV) | on test vector 0, cfg="in-place" This patch fixes this by reworking the crypto4xx_setkey_aes() function to: - not save the iv for ECB (as per 18.2.38 CRYP0_SA_CMD_0: "This bit mut be cleared for DES ECB mode or AES ECB mode, when no IV is used.") - instruct the hardware to save the generated IV for all other modes of operations that have IV and then supply it back to the callee in pretty much the same way as we do it for cbc-aes already. - make it clear that the DIR_(IN|OUT)BOUND is the important bit that tells the hardware to encrypt or decrypt the data. (this is cosmetic - but it hopefully prevents me from getting confused again). - don't load any bogus hash when we don't use any hash operation to begin with.
