crypto: ccree - swap SHA384 and SHA512 larval hashes at build time

2023-01-18T10:41:18Z

[ Upstream commit f08b58501c74d6ec0828b55a0d4e0b2e840c2b9e ] Due to the way the hardware works, every double word in the SHA384 and SHA512 larval hashes must be swapped. Currently this is done at run time, during driver initialization. However, this swapping can easily be done at build time. Treating each double word as two words has the benefit of changing the larval hashes' types from u64[] to u32[], like for all other hashes, and allows dropping the casts and size doublings when calling cc_set_sram_desc().

crypto: ccree - Rename arrays to avoid conflict with crypto/sha256.h

2019-09-05T04:54:54Z

Rename the algo_init arrays to cc_algo_init so that they do not conflict with the functions declared in crypto/sha256.h. This is a preparation patch for folding crypto/sha256.h into crypto/sha.h. Signed-off-by: Hans de Goede Acked-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - don't map MAC key on stack

2019-04-25T07:38:15Z

The MAC hash key 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 Cc: stable@vger.kernel.org # v4.19+ Signed-off-by: Herbert Xu

crypto: ccree - use correct internal state sizes for export

2019-04-25T07:38:15Z

We were computing the size of the import buffer based on the digest size but the 318 and 224 byte variants use 512 and 256 bytes internal state sizes respectfully, thus causing the import buffer to overrun. Fix it by using the right sizes. Signed-off-by: Gilad Ben-Yossef Cc: stable@vger.kernel.org # v4.19+ Signed-off-by: Herbert Xu

crypto: ccree - copyright header update

crypto: ccree - use proper callback completion api

Use proper hash callback completion API instead of open coding it. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - fix backlog notifications

2019-04-25T07:38:14Z

We were doing backlog notification callbacks via a cipher/hash/aead request structure cast to the base structure, which may or may not work based on how the structure is laid in memory and is not safe. Fix it by delegating the backlog notification to the appropriate internal callbacks which are type aware.
