* crypto: x86/morus1280 - convert to use AEAD SIMD helpersEric Biggers2019-03-221-85/+0
| | | | | | | | | | Convert the x86 implementations of MORUS-1280 to use the AEAD SIMD helpers, rather than hand-rolling the same functionality. This simplifies the code and also fixes the bug where the user-provided aead_request is modified.

* crypto: x86/morus - fix handling chunked inputs and MAY_SLEEPEric Biggers2019-02-081-24/+16
| | | | | | | | | | | | | | | | | | | | | The x86 MORUS implementations all fail the improved AEAD tests because they produce the wrong result with some data layouts. The issue is that they assume that if the skcipher_walk API gives 'nbytes' not aligned to the walksize (a.k.a. walk.stride), then it is the end of the data. In fact, this can happen before the end. Also, when the CRYPTO_TFM_REQ_MAY_SLEEP flag is given, they can incorrectly sleep in the skcipher_walk_*() functions while preemption has been disabled by kernel_fpu_begin(). Fix these bugs.

* crypto: morus - Mark MORUS SIMD glue as x86-specificOndrej Mosnacek2018-05-301-0/+302
Commit 56e8e57fc3a7 ("crypto: morus - Add common SIMD glue code for MORUS") accidetally consiedered the glue code to be usable by different architectures, but it seems to be only usable on x86. This patch moves it under arch/x86/crypto and adds 'depends on X86' to the Kconfig options and also removes the prompt to hide these internal options from the user.
