2019-04-25crypto: ccree - don't map AEAD key and IV on stackGilad Ben-Yossef
The AEAD authenc key and IVs might be passed to us on stack. Copy it to a slab buffer before mapping to gurantee proper DMA mapping. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Cc: stable@vger.kernel.org # v4.19+ Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2019-04-25crypto: ccree - simplify fragment ICV detectionGilad Ben-Yossef
The code detecting whether the ICV is fragmented was overly complex and limited the number of fragments an ICV may be comprised of with no reason in the current code, casuing the new testmgr tests to fail. This patch removes this legacy limitation and greatly simplifies the code. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2018-11-09crypto: ccree - adjust hash length to suit certain context specificsYael Chemla
Adjust hash length such that it will not be fixed and general for all algs. Instead make it suitable for certain context information. This is preparation for SM3 support. Signed-off-by: Yael Chemla <yael.chemla@foss.arm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2018-11-09crypto: ccree - add support for CryptoCell 713Gilad Ben-Yossef
Add support for Arm TrustZone CryptoCell 713. Note that this patch just enables using a 713 in backwards compatible mode to 712. Newer 713 specific features will follow. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2018-08-03crypto: ccree - drop useless type flag during regGilad Ben-Yossef
Drop the explicit setting of CRYPTO_ALG_TYPE_AEAD or CRYPTO_ALG_TYPE_SKCIPHER flags during alg registration as they are set anyway by the framework. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2018-05-31crypto: ccree - correct host regs offsetGilad Ben-Yossef
The product signature and HW revision register have different offset on the older HW revisions. This fixes the problem of the driver failing sanity check on silicon despite working on the FPGA emulation systems.
