crypto: qce - fix error return code in qce_skcipher_async_req_handle()

2021-06-11T07:03:29Z

Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function.

crypto: qce: skcipher: Fix incorrect sg count for dma transfers

2021-05-28T07:11:45Z

Use the sg count returned by dma_map_sg to call into dmaengine_prep_slave_sg rather than using the original sg count. dma_map_sg can merge consecutive sglist entries, thus making the original sg count wrong. This is a fix for memory coruption issues observed while testing encryption/decryption of large messages using libkcapi framework. Patch has been tested further by running full suite of tcrypt.ko tests including fuzz tests. Signed-off-by: Thara Gopinath Signed-off-by: Herbert Xu

2021-05-14T11:07:56Z

Qualcomm crypto engine does not handle the following scenarios and will issue an abort. In such cases, pass on the transformation to a fallback algorithm. - DES3 algorithms with all three keys same. - AES192 algorithms. - 0 length messages. Signed-off-by: Thara Gopinath Signed-off-by: Herbert Xu

crypto: qce - Add support for AEAD algorithms

2021-05-14T11:07:55Z

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

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 - Make result dump optional

2021-05-14T11:07:55Z

Qualcomm crypto engine allows for IV registers and status register to be concatenated to the output. This option is enabled by setting the RESULTS_DUMP field in GOPROC register. This is useful for most of the algorithms to either retrieve status of operation or in case of authentication algorithms to retrieve the mac. But for ccm algorithms, the mac is part of the output stream and not retrieved from the IV registers, thus needing a separate buffer to retrieve it. Make enabling RESULTS_DUMP field optional so that algorithms can choose whether or not to enable the option. Note that in this patch, the enabled algorithms always choose RESULTS_DUMP to be enabled. But later with the introduction of ccm algorithms, this changes. Reviewed-by: Bjorn Andersson Signed-off-by: Thara Gopinath Signed-off-by: Herbert Xu
