#include "../../internal.h"
Work around language and compiler bug in memcpy, etc. Most C standard library functions are undefined if passed NULL, even when the corresponding length is zero. This gives them (and, in turn, all functions which call them) surprising behavior on empty arrays. Some compilers will miscompile code due to this rule. See also https://www.imperialviolet.org/2016/06/26/nonnull.html Add OPENSSL_memcpy, etc., wrappers which avoid this problem.

// The 32-bit hash algorithms share a common byte-order neutral collector and
// padding function implementations that operate on unaligned data,
Fix undefined pointer casts in SHA-512 code. Casting an unaligned pointer to uint64_t* is undefined, even on platforms that support unaligned access. Additionally, dereferencing as uint64_t violates strict aliasing rules. Instead, use memcpys which we assume any sensible compiler can optimize. Also simplify the PULL64 business with the existing CRYPTO_bswap8. This also removes the need for the SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA logic. The generic C code now handles unaligned data and the assembly already can as well. (The only problematic platform with assembly is old ARM, but sha512-armv4.pl already handles this via an __ARM_ARCH__ check. See also OpenSSL's version of this file which always defines SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA if SHA512_ASM is defined.) Add unaligned tests to digest_test.cc, so we retain coverage of unaligned EVP_MD inputs.

// ../digest/md32_common.h. SHA-512 is the only 64-bit hash algorithm, as of
// this writing, so there is no need for a common collector/padding
// implementation yet.
Allow SHA-512 unaligned data access in |OPENSSL_NO_ASM| mode. The previous logic only defined |SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA| when the assembly language optimizations were enabled, but |SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA| is also useful when the C implementations are used. If support for ARM processors that don't support unaligned access is important, then it might be better to condition the enabling of |SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA| on ARM based on more specific flags.

Use UINT64_C instead of OPENSSL_U64. stdint.h already has macros for this. The spec says that, in C++, __STDC_CONSTANT_MACROS is needed, so define it for bytestring_test.cc. Chromium seems to use these macros without trouble, so I'm assuming we can rely on them.

Fix undefined pointer casts in SHA-512 code. Casting an unaligned pointer to uint64_t* is undefined, even on platforms that support unaligned access. Additionally, dereferencing as uint64_t violates strict aliasing rules. Instead, use memcpys which we assume any sensible compiler can optimize. Also simplify the PULL64 business with the existing CRYPTO_bswap8. This also removes the need for the SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA logic. The generic C code now handles unaligned data and the assembly already can as well. (The only problematic platform with assembly is old ARM, but sha512-armv4.pl already handles this via an __ARM_ARCH__ check. See also OpenSSL's version of this file which always defines SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA if SHA512_ASM is defined.) Add unaligned tests to digest_test.cc, so we retain coverage of unaligned EVP_MD inputs.

Revert md_len removal from SHA256_CTX and SHA512_CTX. This reverts commits: - 91586371422dae70481c39752e55f01f50e9a93a - a90aa643024459c1698dbec84f4c79a3238b3db8 - c0d8b83b4462a0eb1889f32dbd7f46e83f4dbc81 It turns out code outside of BoringSSL also mismatches Init and Update/Final functions. Since this is largely cosmetic, it's probably not worth the cost to do this.

Improve crypto/digest/md32_common.h mechanism. The documentation in md32_common.h is now (more) correct with respect to the most important details of the layout of |HASH_CTX|. The documentation explaining why sha512.c doesn't use md32_common.h is now more accurate as well. Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer to the |HASH_CTX| and the assembly language implementations took a pointer to the hash state |h| member of |HASH_CTX|. (This worked because |h| is always the first member of |HASH_CTX|.) Now, the C implementations take a pointer directly to |h| too. The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash state in an array. This will break source compatibility with any external code that accesses the hash state directly, but will not affect binary compatibility. The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type |const uint8_t *|; previously it was |void *| and all implementations had a |uint8_t *data| variable to access it as an array of bytes. This change paves the way for future refactorings such as automatically generating the |*_Init| functions and/or sharing one I-U-F implementation across all digest algorithms.

Improve crypto/digest/md32_common.h mechanism. The documentation in md32_common.h is now (more) correct with respect to the most important details of the layout of |HASH_CTX|. The documentation explaining why sha512.c doesn't use md32_common.h is now more accurate as well. Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer to the |HASH_CTX| and the assembly language implementations took a pointer to the hash state |h| member of |HASH_CTX|. (This worked because |h| is always the first member of |HASH_CTX|.) Now, the C implementations take a pointer directly to |h| too. The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash state in an array. This will break source compatibility with any external code that accesses the hash state directly, but will not affect binary compatibility. The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type |const uint8_t *|; previously it was |void *| and all implementations had a |uint8_t *data| variable to access it as an array of bytes. This change paves the way for future refactorings such as automatically generating the |*_Init| functions and/or sharing one I-U-F implementation across all digest algorithms.

Fix undefined pointer casts in SHA-512 code. Casting an unaligned pointer to uint64_t* is undefined, even on platforms that support unaligned access. Additionally, dereferencing as uint64_t violates strict aliasing rules. Instead, use memcpys which we assume any sensible compiler can optimize. Also simplify the PULL64 business with the existing CRYPTO_bswap8. This also removes the need for the SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA logic. The generic C code now handles unaligned data and the assembly already can as well. (The only problematic platform with assembly is old ARM, but sha512-armv4.pl already handles this via an __ARM_ARCH__ check.

Fix undefined pointer casts in SHA-512 code. Casting an unaligned pointer to uint64_t* is undefined, even on platforms that support unaligned access. Additionally, dereferencing as uint64_t violates strict aliasing rules. Instead, use memcpys which we assume any sensible compiler can optimize. Also simplify the PULL64 business with the existing CRYPTO_bswap8. This also removes the need for the SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA logic. The generic C code now handles unaligned data and the assembly already can as well. (The only problematic platform with assembly is old ARM, but sha512-armv4.pl already handles this via an __ARM_ARCH__ check. See also OpenSSL's version of this file which always defines SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA if SHA512_ASM is defined.) Add unaligned tests to digest_test.cc, so we retain coverage of unaligned EVP_MD inputs.

Improve crypto/digest/md32_common.h mechanism. The documentation in md32_common.h is now (more) correct with respect to the most important details of the layout of |HASH_CTX|. The documentation explaining why sha512.c doesn't use md32_common.h is now more accurate as well. Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer to the |HASH_CTX| and the assembly language implementations took a pointer to the hash state |h| member of |HASH_CTX|. (This worked because |h| is always the first member of |HASH_CTX|.) Now, the C implementations take a pointer directly to |h| too. The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash state in an array. This will break source compatibility with any external code that accesses the hash state directly, but will not affect binary compatibility. The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type |const uint8_t *|; previously it was |void *| and all implementations had a |uint8_t *data| variable to access it as an array of bytes. This change paves the way for future refactorings such as automatically generating the |*_Init| functions and/or sharing one I-U-F implementation across all digest algorithms.
