2018-10-08crypto: morus/generic - fix for big endian systemsArd Biesheuvel
Omit the endian swabbing when folding the lengths of the assoc and crypt input buffers into the state to finalize the tag. This is not necessary given that the memory representation of the state is in machine native endianness already. This fixes an error reported by tcrypt running on a big endian system: alg: aead: Test 2 failed on encryption for morus640-generic 00000000: a8 30 ef fb e6 26 eb 23 b0 87 dd 98 57 f3 e1 4b 00000010: 21 alg: aead: Test 2 failed on encryption for morus1280-generic 00000000: 88 19 1b fb 1c 29 49 0e ee 82 2f cb 97 a6 a5 ee 00000010: 5f Fixes: 396be41f16fd ("crypto: morus - Add generic MORUS AEAD implementations") Cc: <stable@vger.kernel.org> # v4.18+ Reviewed-by: Ondrej Mosnacek <omosnace@redhat.com> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2018-07-09crypto: aead - remove useless setting of type flagsEric Biggers
Some aead algorithms set .cra_flags = CRYPTO_ALG_TYPE_AEAD. But this is redundant with the C structure type ('struct aead_alg'), and crypto_register_aead() already sets the type flag automatically, clearing any type flag that was already there. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the aead algorithms. This patch shouldn't change any actual behavior.

2018-05-19crypto: morus - Add generic MORUS AEAD implementationsOndrej Mosnacek
This patch adds the generic implementation of the MORUS family of AEAD algorithms (MORUS-640 and MORUS-1280). The original authors of MORUS are Hongjun Wu and Tao Huang. At the time of writing, MORUS is one of the finalists in CAESAR, an open competition intended to select a portfolio of alternatives to the problematic AES-GCM: https://competitions.cr.yp.to/caesar-submissions.html https://competitions.cr.yp.to/round3/morusv2.pdf Signed-off-by: Ondrej Mosnacek <omosnacek@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
