wolfssl/wolfcrypt/aes.h: add key_C_fallback[] to struct Aes, and remove comment that "AESNI needs key first, rounds 2nd, not sure why yet" now that AES_128_Key_Expansion_AESNI no longer writes rounds after the expanded key.
wolfcrypt/src/aes.c:
* add _AESNI or _aesni suffixes/infixes to AESNI implementations that were missing them: AES_CBC_encrypt(), AES_CBC_decrypt_by*(), AES_ECB_encrypt(), AES_*_Key_Expansion(), AES_set_encrypt_key(), AES_set_decrypt_key(), AES_GCM_encrypt(), AES_GCM_decrypt(), AES_XTS_encrypt(), and AES_XTS_decrypt().
* move key size check from to start of wc_AesSetKeyLocal().
* refactor pure-C AES setkey and cipher implementations to use aes->key_C_fallback when defined(WC_AES_C_DYNAMIC_FALLBACK).
* refactor wc_AesSetKeyLocal() to set up both AESNI and pure-C expanded keys when defined(WC_AES_C_DYNAMIC_FALLBACK).
* refactor all (haveAESNI && aes->use_aesni) conditions to just (aes->use_aesni).
* add macros VECTOR_REGISTERS_PUSH and VECTOR_REGISTERS_POP, which do nothing but push a brace level when !defined(WC_AES_C_DYNAMIC_FALLBACK), but when defined(WC_AES_C_DYNAMIC_FALLBACK), they call SAVE_VECTOR_REGISTERS2() and on failure, temporarily clear aes->use_aesni and restore at _POP().
* refactor all invocations of SAVE_VECTOR_REGISTERS() and RESTORE_VECTOR_REGISTERS() to VECTOR_REGISTERS_PUSH and VECTOR_REGISTERS_POP, except in wc_AesSetKeyLocal(), wc_AesXtsEncrypt(), and wc_AesXtsDecrypt(), which are refactored to use SAVE_VECTOR_REGISTERS2(), with graceful failure concealment if defined(WC_AES_C_DYNAMIC_FALLBACK).
* orthogonalize cleanup code in wc_AesCbcEncrypt(), wc_AesCcmEncrypt() and wc_AesCcmDecrypt().
* streamline fallthrough software definitions of wc_AesEncryptDirect() and wc_AesDecryptDirect(), and remove special-casing for defined(WOLFSSL_LINUXKM)&&defined(WOLFSSL_AESNI).
wolfcrypt/src/aes_asm.{S,asm}:
* remove errant "movl $10, 240(%rsi)" from AES_128_Key_Expansion_AESNI.
* add _AESNI suffixes/infixes to implementations that needed them.
wolfcrypt/src/{aes_gcm_asm.{S,asm},aes_xts_asm.S}: regenerate from revisions in scripts#357 -- adds _aesni suffixes to implementations that were missing them.
wolfssl/wolfcrypt/types.h: remove DEBUG_VECTOR_REGISTER_ACCESS macros, and add dummy fallthrough definitions for SAVE_VECTOR_REGISTERS2 and WC_DEBUG_SET_VECTOR_REGISTERS_RETVAL.
wolfssl/wolfcrypt/memory.h: adopt DEBUG_VECTOR_REGISTER_ACCESS code from types.h, and add definitions for WC_DEBUG_VECTOR_REGISTERS_RETVAL_INITVAL and WC_DEBUG_SET_VECTOR_REGISTERS_RETVAL.
linuxkm/linuxkm_wc_port.h: add arch-specific macro definitions for SAVE_VECTOR_REGISTERS2().
wolfcrypt/benchmark/benchmark.c: add missing gates around calls to RESTORE_VECTOR_REGISTERS().
configure.ac:
* cover various interdependencies in enable-all/enable-all-crypto, for better behavior in combination with --disable-aesgcm, --disable-ecc, --disable-ocsp, --disable-hmac, --disable-chacha, --disable-ed25519, and --disable-ed448.
* inhibit aesgcm_stream in enable-all/enable-all-crypto when ENABLED_LINUXKM_DEFAULTS, because it is currently incompatible with WC_AES_C_DYNAMIC_FALLBACK.
* add -DWC_AES_C_DYNAMIC_FALLBACK when ENABLED_LINUXKM_DEFAULTS.
* add 3 new interdependency checks: "ECCSI requires ECC.", "SAKKE requires ECC.", "WOLFSSH requires HMAC."
wolfcrypt/src/asn.c: tweak gating to accommodate defined(NO_RSA) && !defined(HAVE_ECC).
wolfcrypt/src/evp.c: tweak gating to accommodate defined(NO_HMAC).
wolfcrypt/src/logging.c: remove DEBUG_VECTOR_REGISTER_ACCESS code (moved to memory.c).
wolfcrypt/src/memory.c: change #include of settings.h to types.h; adopt DEBUG_VECTOR_REGISTER_ACCESS code from logging.c; add implementation of SAVE_VECTOR_REGISTERS2_fuzzer().
wolfcrypt/src/pwdbased.c: add explanatory #error scrypt requires HMAC.
wolfcrypt/test/test.c:
* add DEBUG_VECTOR_REGISTER_ACCESS clauses to aes_xts_128_test(), aesecb_test(), aesctr_test(), aes_test() CBC section, aes256_test() CBC section, and aesgcm_default_test_helper()
* remove duplicate wc_AesEcbDecrypt() in aesecb_test().
* add gating for pbkdf2_test().
* fix cleanup code in dsa_test().
* fix gating in pkcs7authenveloped_run_vectors() to accommodate !defined(HAVE_AESGCM).
* fix gating in cryptocb_test() to accommodate defined(NO_HMAC).
wolfssl/wolfcrypt/cryptocb.h: remove gates around "pk" sub-struct of struct wc_CryptoInfo -- wc_CryptoInfo.pk.type (an int) is used unconditionally when --enable-debug, and is used with DH.
wolfssl/wolfcrypt/error-crypt.h: fix whitespace.
Added new x86 assembly for AES.
AES-CBC decrypt only 4 blocks at a time (not 6 or 8) due to reduces
register count.
GCM implementation for AVX2, AVX1 and AESNI only.
Disabled looking for other assembly files for x86.
Some versions of GCC on the Mac will not run the file aes_asm.s through the preprocessor. There are some ifdefs in the file that are included when they shouldn't be. This is not a problem on Linux. Renaming the file to have a capital S extension forces the assembler to run with the preprocessor.
