wolfssl/wolfcrypt/src/hash.c
David Garske c1640e8a3d Intel QuickAssist (QAT) support and async enhancements/fixes: 
* Adds ./configure "--with-intelqa=../QAT1.6”, port files, memory management and README.md (see wolfcrypt/src/port/intel/).
* Added Intel QAT support for RSA public/private (CRT/non-CRT), AES CBC/GCM, ECDH/ECDSA, DH, DES3, SHA, SHA224, SHA256, SHA384, SHA512, MD5 and HMAC.
* wolfSSL async enabled all client and server: PKI, Encrypt/Decrypt, Hashing/HMAC and Certificate Sign/Verify.
* wolfSSL async support in functions: Encrypt, Decrypt, VerifyMAC, BuildMessage, ConfirmSignature, DoCertificate, ParseCertRelative, and MakeSignature.
* wolfCrypt test and benchmark async support added for all HW acceleration.
* wolfCrypt benchmark multi-threading support.
* Added QuickAssist memory overrides for XMALLOC, XFREE and XREALLOC. XREALLOC determines if existing pointer needs reallocated for NUMA.
* Refactor to make sure “heap” is available for async dev init.
* Added async support for all examples for connect, accept, read and write.
* Added new WC_BIGINT (in wolfmath.c) for async hardware support.
* Added async simulator tests for DES3 CBC, AES CBC/GCM.
* Added QAT standalone build for unit testing.
* Added int return code to SHA and MD5 functions.
* Refactor of the async stack variable handling, so async operations have generic args buffer area and cleanup function pointer.
* Combined duplicate code for async push/pop handling.
* Refactor internal.c to add AllocKey / FreeKey.
* Refactor of hash init/free in TLS to use InitHashes and FreeHashes.
* Refactor of the async event->context to use WOLF_EVENT_TYPE_ASYNC_WOLFSSL for WOLFSSL* and WOLF_EVENT_TYPE_ASYNC_WOLFCRYPT for WC_ASYNC_DEV*.
* Suppress error message for WC_PENDING_E.
* Implemented "wolfSSL_EVP_MD_CTX_init" to do memset.
* Cleanup of the openssl compat CTX sizes when async is enabled.
* Cleanup of AES, DES3, DH, SHA, MD5, DES3, DH, HMAC, MD5 for consistency and readability.
* Cleanup of the OPAQUE_LEN.
* Cleanup to use ENCRYPT_LEN instead of sizeof(ssl->arrays.preMasterSecret).
* Changed ssl->arrays.preMasterSecret to use XMALLOC (accelerates HW operations)
* Reduce verbosity with debug enabled for "GetMyVersion", "wolfSSL Using RSA OAEP padding" and "wolfSSL Using RSA PKCSV15 padding".
* Updated RSA un-padding error message so its different than one above it for better debugging.
* Added QAT async enables for each algorithm.
* Refactor of the async init to use _ex.
* Added WC_ASYNC_THRESH_NONE to allow bypass of the async thresholds for testing.
* Reformatted the benchmark results:
PKI: "RSA 2048 private HW 18522 ops took 1.003 sec, avg 0.054 ms, 18467.763 ops/sec"
Crypto/Hashing: SHA-256 SW 350 megs took 1.009 seconds, 346.946 MB/s Cycles per byte = 9.87
* Added min execution time for all benchmarks.
* Moved wc_*GetHash and wc_*RestorePos to appropriate files so use of isCopy flag is local.
* Fix for ECC sign status sometimes being invalid due to uninitialized ECC digest in benchmark.
* Added new DECLARE_VAR/FREE_VAR and DECLARE_ARRAY/FREE_ARRAY macros for helping setup test/benchmark variables to accelerate async.
* Added NO_SW_BENCH option to only run HW bench.
* Added support for PRNG to use hardware SHA256 if _wc devId provided.
* Fix to prevent curve tests from running against wrong curve sizes. Changed wc_ecc_set_curve to match on exact size.
* Added the wc_*GetHash calls to the wolfCrypt tests.
* Added async hardware start/stop to wolfSSL init/cleanup.
* Refactor to add wc_*Copy for hashing context (for async), which replaces wc_*RestorePos.
* Fixes for building with TI hashing (including: SHA224, missing new API’s and building with dummy build for non hw testing). Note: We need to add build test for this `./configure CFLAGS="-DWOLFSSL_TI_HASH -DTI_DUMMY_BUILD”`.
* Added arg checks on wc_*GetHash and wc_*Copy.
* Cleanup of the BuildMD5, BuildSHA, BuildMD5_CertVerify and BuildSHA_CertVerify functions.
* Added new ./configure --enable-asyncthreads, to allow enable/disable of the async threading support. If --enable-asynccrypt set this will be enabled by default if pthread is supported. Allows multi-threaded benchmarks with async simulator.
* Added checks for all hashing to verify valid ->buffLen.
* Fix for SHA512 scan-build warning about un-initialized “W_X”.
* Fix for valgrind un-initialized use of buffer in AllocDer (der->buffer) and BuildTlsFinished handshake_hash.
* Refactor of the benchmarking to use common function for start, check and finish of the stats.
* Fixed issue with ECC cache loading in multi-threading.
* Fix bug with AESNI not aligned code that assumes XMALLOC is 16-byte aligned.
* Added new WC_ASYNC_NO_… options to allow disabling of individual async algorithms. New defines are: WC_ASYNC_NO_CRYPT, WC_ASYNC_NO_PKI and WC_ASYNC_NO_HASH. Additionally each algorithm has a WC_ASYNC_NO_[ALGO] define.
* Added “wolfSSL_GetAllocators” API and fixed the wolfCrypt memcb_test so it restores callback pointers after test is complete (fixes issue with using custom allocators and test breaking it).
