2018-09-14crypto: x86/aegis,morus - Do not require OSXSAVE for SSE2Ondrej Mosnacek1-1/+0
It turns out OSXSAVE needs to be checked only for AVX, not for SSE. Without this patch the affected modules refuse to load on CPUs with SSE2 but without AVX support.

2018-08-07crypto: x86/aegis,morus - Fix and simplify CPUID checksOndrej Mosnacek1-8/+4
It turns out I had misunderstood how the x86_match_cpu() function works. It evaluates a logical OR of the matching conditions, not logical AND. This caused the CPU feature checks for AEGIS to pass even if only SSE2 (but not AES-NI) was supported (or vice versa), leading to potential crashes if something tried to use the registered algs. This patch switches the checks to a simpler method that is used e.g. in the Camellia x86 code. The patch also removes the MODULE_DEVICE_TABLE declarations which actually seem to cause the modules to be auto-loaded at boot, which is not desired. The crypto API on-demand module loading is sufficient.

2018-05-19crypto: x86 - Add optimized AEGIS implementationsOndrej Mosnacek1-0/+407
This patch adds optimized implementations of AEGIS-128, AEGIS-128L, and AEGIS-256, utilizing the AES-NI and SSE2 x86 extensions. Signed-off-by: Ondrej Mosnacek <omosnacek@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
