wolfcrypt/src/coding.c: in Base64_Decode() and Base64_Decode_nonCT(), check for non-whitespace characters past the end and return ASN_INPUT_E if found;
wolfcrypt/test/test.c: in base64_test(), remove ';' from goodChar[], and add trailing*[] test strings and N_BYTE_TRAILING_TEST(), for positive and negative testing of new checks.
PPC64:

- Added SHA-256/512 using base scalar and crypto instructions
- Added SHA-3 using base scalar and POWER8 VSX
- Added SHA-3 x2/x3 but disabled compilation.
- Added CPU id flags.
- Changed the constant data format to be consistent with other platforms.
PPC32:
- Added AES-ECB/CBC/CTR/GCM/XTS using base scalar
- Added SHA-256/512 using base scalar
- Added SHA-3 using base scalar
Fix Thumb2 Curve25519 asm to do full reduce.
Change ARM32 to simpler carry/overflow processing.
Minor optimizations - use ubfx, no need to move register into temporary, cache value instead of loading again later.
Reduce the register push and pops in Thumb2 generated code.
Fix Thumb2 to have values less than 64 in decimal.
linuxkm/: when logging PTR_ERR(), cast it to int, and use "%d" as the format. Globally, `#define PTR_ERR(x) ((int)PTR_ERR(x))` in linuxkm_wc_port.h to fix clang warnings on kernel headers.
linuxkm/lkcapi_aes_glue.c: add casts in linuxkm_test_aesgcm() to mollify clang.
linuxkm/linuxkm_wc_port.h, linuxkm/module_hooks.c:
* add __clang__ compat code to allow including clang stdatomic.h while masking out kernel-incompatible __CLANG_STDINT_H.
* add clang-specific suppressions for kernel headers (-Wshorten-64-to-32, -Wframe-address).
linuxkm/lkcapi_sha_glue.c:
* in wc__get_random_bytes(), add bounds-checking for len.
* in wc_extract_crng_user(), fix type conflicts.
wolfssl/wolfcrypt/wc_port.h and wolfssl/wolfcrypt/types.h:
* move the old-FIPS compatibility mapping from INLINE to WC_INLINE from types.h to wc_port.h.
* activate stdatomic.h for clang kernel module builds.
linuxkm/Kbuild:
* add clang-specific flags.
* add gcc gate around gcc-specific flags.
* allow override value for MAX_STACK_FRAME_SIZE.
wolfcrypt/src/asn.c: add casts in GetFormattedTime_ex() to mollify clang build of linuxkm.
* wolfssl/ocsp.h: gate out the CheckOcspResponder() prototype if defined(CheckOcspResponder) (for linuxkm-pie).
* wolfcrypt/src/wc_mldsa.c: add support for WC_MLDSA_NO_ASM.
* .wolfssl_known_macro_extras: add new macros.
* in slhdsa_keygen_kat() and slhdsa_id_label_test(), pass devId to wc_SlhDsaKey_Init*()
* in cryptocb_test(), inhibit the callback verification check for SLHDSA if FIPS (no crypto callbacks in FIPS-wrapped calls).
* implement wc_local_AesGcmCheckTagSz() with pedantic checks for valid authtag size. SP 800-38D restrictions are now uniformly imposed, unless WC_AES_GCM_ALLOW_NONSTANDARD_TAG_LENGTH is defined (not allow with FIPS).
* refactor tag size checks in wc_AesGcmEncrypt(), wc_AesGcmDecrypt(), wc_AesGcmEncryptFinal(), wc_AesGcmDecryptFinal(), and wc_PKCS7_DecodeAuthEnvelopedData().
* in test.c, update aesgcm_non12iv_test() to skip tag sizes expected to fail.
* add WC_VAES_MIN_BLOCKS, WC_VAES_ECB_MIN_BLOCKS, and WC_VAES_GCM_MIN_BLOCKS, and check against them before using AVX512/VAES implementations.
* in AesCfbDecrypt_C(), enlarge the tmp[] buffer and parameterize its size with newly added WC_AES_CFB_DEC_BUF_BLOCKS.
linuxkm/linuxkm_memory.c: use packed-struct intermediates rather than memcpy()s for wc_get_unaligned() and wc_put_unaligned().
linuxkm/linuxkm_wc_port.h: on old FIPS, retrofit nonnull attribute to GHASH() arg 1, so that it unconditionally writes out the hash.
wolfcrypt/src/aes.c and wolfssl/wolfcrypt/aes.h: in GHASH(), add nonnull attribute to arg 1, and remove runtime nullness check for arg 1 in the implementations.
ARM64/ARM32/Thumb2:
- Inline-asm use param names not registers.
- Return value through first parameter and not first register
- 32-bit values zero extended when loaded off stack
aes.c: Aligned-accedd GHASH for 32-bit CPUs.
test.c: #ifdef protection update.
sha3.h: make digest and block size constants defines for use in hash.h
sha512.h: internal Transform_Sha512* functions declared when only SHA-384.
sp_int.h: include WOLFSSL_SP_MATH_ALL in SP_INT_BITS selection
memory.c: fix printf format to be compatible with more platforms
With WOLFSSL_SMALL_STACK_CACHE, wc_Sha512Free and wc_Sha384Free freed the
cached W buffer as DYNAMIC_TYPE_TMP_BUFFER, but it is allocated as
DYNAMIC_TYPE_DIGEST in InitSha512_Family/InitSha384 and the Copy functions
(the in-Init error cleanup already frees it as DYNAMIC_TYPE_DIGEST).
The mismatch is flagged by the memusage test (DHE_RSA TLS1.2 reports
Errors: 2) and matters for type-bucketed static memory pools. SHA-256/224
already use DYNAMIC_TYPE_DIGEST consistently. Free W as DYNAMIC_TYPE_DIGEST.
use target native int for WC_ATOMIC_INT_ARG, add user overrideability, and
adjust WC_INIT_STATE_COUNT_BITS to depend on sizeof(WC_ATOMIC_UINT_ARG). add
a wc_static_assert to sanity-check WC_INIT_STATE_STATE_BITS, and use CHAR_BIT
opportunistically in the other wc_static_assert to sanity check that CHAR_BIT
is at least 8.
Support AES-XTS AVX512/VAES
Support AES-GCM AVX512/VAES
Support AES-ECB/CBC/CTR AVX512/VAES/AVX1/AES-NI.
Remove code from aes_asm.S/aes_asm.asm
Add CPU defines for AVX512 and VAES
Updated ASM files with new defines for AVX512.
Added support for printing out the new CPU Id flags in benchmark.
Added new files to Windows projects.
aes.c: Supports ECB/CBC/CTR in assembly. Supports calling AVX512/VAES assembly.
* in USE_WINDOWS_API wc_GenerateSeed(), recognize HAVE_AMD_RDSEED, and properly enforce FORCE_FAILURE_RDSEED when CPU support is missing;
* in WOLFSSL_LINUXKM wc_GenerateSeed(), initialize ret to RNG_FAILURE_E, and properly enforce FORCE_FAILURE_RDSEED when CPU support is missing;
* in WOLFSSL_BSDKM wc_GenerateSeed(), properly enforce FORCE_FAILURE_RDSEED when CPU support is missing;
Allow x86 to build with assembly for enable all - disable assembly when x86 and not assembly code available. Add file fe_operations.c when assembly and x86.
x86: fix ECB decrypt to use corect offsets for parameters
fix AES-NI and AVX1 assembly code
fix sp_int with assembly to compile
minor optimizations of AES-GCM
x64: Don't emit move instruction if source and destination are the same reg
Use xor instead of mov 0
minor optimizations of AES-GCM for AES-NI
wolfcrypt/test/test.c: add missing !HAVE_SELFTEST gate around AES-CCM counter overflow test in aesccm_128_badarg_test();
wolfcrypt/src/error.c and wolfssl/wolfcrypt/error-crypt.h: update messages for AES_{GCM,CCM}_OVERFLOW_E.
DecodeExtensionType() guarded the certificatePolicies duplicate check
(VERIFY_AND_SET_OID) under WOLFSSL_SEP only, because the extCertPolicySet
tracking bit was SEP-only. In a WOLFSSL_CERT_EXT-without-WOLFSSL_SEP build a
cert with two certificatePolicies extensions was accepted and the second
silently overwrote the first (RFC 5280 4.2 forbids repeats). Make the bit and
the guard available under WOLFSSL_CERT_EXT too, matching every other
non-repeatable extension.
Add test_DecodeCertExtensions_dup_certpol (DecodeExtensionType now
WOLFSSL_TEST_VIS).
Instead of failing when top bit is set, the standard and current research says to mask it.
WOLFSSL_X25519_NO_MASK_PEER is added to allow the rejection when required.
Use readUnaligned32/64 to ensure no unaligned read faults.
Updated implementations of read/write unaligned 32/64 to not worry about alignment on CPUs that are known to not care.
