crypto: qce - Add support for AEAD algorithms

2021-05-14T11:07:55+00:00

Introduce support to enable following algorithms in Qualcomm Crypto Engine. - authenc(hmac(sha1),cbc(des)) - authenc(hmac(sha1),cbc(des3_ede)) - authenc(hmac(sha256),cbc(des)) - authenc(hmac(sha256),cbc(des3_ede)) - authenc(hmac(sha256),cbc(aes)) - ccm(aes) - rfc4309(ccm(aes)) Signed-off-by: Thara Gopinath Signed-off-by: Herbert Xu

crypto: qce - Add mode for rfc4309

2021-05-14T11:07:55+00:00

rf4309 is the specification that uses aes ccm algorithms with IPsec security packets. Add a submode to identify rfc4309 ccm(aes) algorithm in the crypto driver. Reviewed-by: Bjorn Andersson Signed-off-by: Thara Gopinath Signed-off-by: Herbert Xu

crypto: qce - Remove totallen and offset in qce_start

2021-03-07T04:13:17+00:00

totallen is used to get the size of the data to be transformed. This is also available via nbytes or cryptlen in the qce_sha_reqctx and qce_cipher_ctx. Similarly offset convey nothing for the supported encryption and authentication transformations and is always 0. Remove these two redundant parameters in qce_start.

crypto: qce - support zero length test vectors

2020-07-03T04:18:34+00:00

crypto test module passes zero length vectors as test input to sha-1 and sha-256. To provide correct output for these vectors, hash zero support has been added as in other crypto drivers. Signed-off-by: Sivaprakash Murugesan Signed-off-by: Herbert Xu

crypto: qce - handle AES-XTS cases that qce fails

2020-02-13T09:05:27+00:00

QCE hangs when presented with an AES-XTS request whose length is larger than QCE_SECTOR_SIZE (512-bytes), and is not a multiple of it. Let the fallback cipher handle them. Signed-off-by: Eneas U de Queiroz Signed-off-by: Herbert Xu

crypto: qce - switch to skcipher API

2019-11-17T01:02:48+00:00

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. Reviewed-by: Stanimir Varbanov Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: qce - Qualcomm crypto engine driver

2014-07-03T13:40:27+00:00

The driver is separated by functional parts. The core part implements a platform driver probe and remove callbaks. The probe enables clocks, checks crypto version, initialize and request dma channels, create done tasklet and init crypto queue and finally register the algorithms into crypto core subsystem. - DMA and SG helper functions implement dmaengine and sg-list helper functions used by other parts of the crypto driver. - ablkcipher algorithms implementation of AES, DES and 3DES crypto API callbacks, the crypto register alg function, the async request handler and its dma done callback function. - SHA and HMAC transforms implementation and registration of ahash crypto type. It includes sha1, sha256, hmac(sha1) and hmac(sha256). - infrastructure to setup the crypto hw contains functions used to setup/prepare hardware registers for all algorithms supported by the crypto block. It also exports few helper functions needed by algorithms: - to check hardware status - to start crypto hardware - to translate data stream to big endian form Adds register addresses and bit/masks used by the driver as well.
