crypto: morus/generic - fix for big endian systems
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>
