[PATCH 00/12] x86/crypto: gcmaes AVX scatter/gather support

From: Dave Watson
Date: Mon Dec 10 2018 - 14:57:07 EST


This patch set refactors the x86 aes/gcm AVX crypto routines to
support true scatter/gather by adding gcm_enc/dec_update methods.

It is similar to the previous SSE patchset starting at e1fd316f.
Unlike the SSE routines, the AVX routines did not support
keysize 192 & 256, this patchset also adds support for those
keysizes.

The final patch updates the C glue code, passing everything through
the crypt_by_sg() function instead of the previous memcpy based
routines.

Dave Watson (12):
x86/crypto: aesni: Merge GCM_ENC_DEC
x86/crypto: aesni: Introduce gcm_context_data
x86/crypto: aesni: Macro-ify func save/restore
x86/crypto: aesni: support 256 byte keys in avx asm
x86/crypto: aesni: Add GCM_COMPLETE macro
x86/crypto: aesni: Split AAD hash calculation to separate macro
x86/crypto: aesni: Merge avx precompute functions
x86/crypto: aesni: Fill in new context data structures
x86/crypto: aesni: Move ghash_mul to GCM_COMPLETE
x86/crypto: aesni: Introduce READ_PARTIAL_BLOCK macro
x86/crypto: aesni: Introduce partial block macro
x86/crypto: aesni: Add scatter/gather avx stubs, and use them in C
