wolfcrypt/src/chacha.c and wolfssl/wolfcrypt/chacha.h: implement USE_ARM_CHACHA_SPEEDUP gate;
wolfcrypt/src/kdf.c: in wc_SSH_KDF(), add early return if _HashInit() fails (fixes _HashFree() of uninited _hash);
wolfcrypt/src/sha256.c: initialize sha256->W in ARMASM variant of wc_InitSha256_ex(), and pass sha256->heap to XMALLOC/XFREE consistently.
refactor all static flag initializations to use cpuid_get_flags_ex() for race-free dynamics;
refactor cpuid_set_flags() to be race-free;
wolfssl/wolfcrypt/wc_port.h and wolfcrypt/src/wc_port.c: add
* WOLFSSL_ATOMIC_COERCE_INT()
* WOLFSSL_ATOMIC_COERCE_UINT()
* wolfSSL_Atomic_Uint
* wolfSSL_Atomic_Uint_Init()
* wolfSSL_Atomic_Int_AddFetch()
* wolfSSL_Atomic_Int_SubFetch()
* wolfSSL_Atomic_Int_CompareExchange()
* wolfSSL_Atomic_Uint_FetchAdd()
* wolfSSL_Atomic_Uint_FetchSub()
* wolfSSL_Atomic_Uint_AddFetch()
* wolfSSL_Atomic_Uint_SubFetch()
* wolfSSL_Atomic_Uint_CompareExchange()
wolfcrypt/test/test.c: add to memory_test() tests for all atomic macros and APIs;
.github/workflows/pq-all.yml: don't use -Wpedantic for CC=c++ scenario.
update wolfcrypt/src/port/af_alg, wolfcrypt/src/port/devcrypto, and wolfcrypt/src/port/kcapi to include libwolfssl_sources.h;
remove a slew of includes across lib sources made redundant by libwolfssl_sources.h.
which force on BUILDING_WOLFSSL and do boilerplate includes, and update library
sources to include them at the top.
wolfssl_sources.h includes types.h, error-crypt.h, and logging.h, and
conditionally, config.h. settings.h and wc_port.h are unconditionally
included at the top of types.h.
wolfssl_sources_asm.h includes settings.h, and conditionally, config.h.
Add wolfssl_sources*.h to wolfcrypt/src/include.am, and to several IDE/ project
files.
Also added a TEST_WOLFSSL_SOURCES_INCLUSION_SEQUENCE clause in
wolfssl/wolfcrypt/settings.h to allow coverage testing.
In wolfcrypt/src/misc.c, retain existing ad hoc boilerplate includes, and use
them if WOLFSSL_VIS_FOR_TESTS, otherwise include the new wolfssl_sources.h.
Define WOLFSSL_VIS_FOR_TESTS at top of wolfcrypt/test/test.c.
Also renamed WOLFSSL_NEED_LINUX_CURRENT to WOLFSSL_LINUXKM_NEED_LINUX_CURRENT,
for clarity.
* sense assert.h and define WOLFSSL_HAVE_ASSERT_H accordingly.
* force off enable_aesgcm_stream if 32 bit armasm or riscv-asm (not yet implemented or buildable).
* add AM_CONDITIONAL([BUILD_CHACHA_NOASM, ...]) when --enable-chacha=noasm.
src/include.am: gate armasm/riscv_asm chacha files on !BUILD_CHACHA_NOASM.
tests/api.c: add missing HAVE_CHACHA&&HAVE_POLY1305 gate around test_TLSX_CA_NAMES_bad_extension().
wolfcrypt/src/chacha.c: tweak WOLFSSL_ARMASM and WOLFSSL_RISCV_ASM codepaths to also depend on !NO_CHACHA_ASM.
wolfssl/wolfcrypt/types.h: in setup for wc_static_assert(), #include <assert.h> if WOLFSSL_HAVE_ASSERT_H, >=C11, or >=C++11.
ChaCha20:
scalar and vector implementations
vector implementations doing 6, 4, 2, 1 block at a time.
scalar implemetations using roriw and pack
vector implementations using VROR_VI and roriw.
RISC-V SHA-256: avoid using s0 if it can be helped.
tests/suites.c: in SuiteTest(), swap order of (void)s and return.
wolfcrypt/src/chacha.c: gate out unreachable C wc_Chacha_encrypt_bytes() call in wc_Chacha_Process, and gate out unused implementations of wc_Chacha_wordtobyte() and wc_Chacha_encrypt_bytes(), when defined(USE_INTEL_CHACHA_SPEEDUP).
wolfcrypt/src/sha256.c and wolfcrypt/src/sha512.c: fix logic in Sha256_SetTransform() and Sha512_SetTransform() to make the AVX1_RORX implementations accessible. also add a missing Transform_Sha512_Len_p = NULL in the C path of Sha512_SetTransform().
wolfssl/internal.h: for the fallback definition of wolfSSL_curve_is_disabled, use an inline function instead of a compound-clause macro, because clang isn't smart enough to treat the compound expression as a bare constant zero, producing a lame-positive -Wunreachable-code.
Add support for compiling ASM for Thumb2
Add Curve25519 ASM for Thumb2
Limit assembly code compiled when Ed25519 not required.
Rework all assembly implementations to replace ge_*() functions instead
of having fe_ge_*() versions that take many parameters.
Get ARM32 inline asm working.
fix for benign clang-analyzer-deadcode.DeadStores in aes.c:wc_AesFeedbackEncrypt();
fix for cppcheck:selfAssignment in chacha.c:wc_Chacha_wordtobyte().
smallstack refactors for wolfcrypt/src/rsa.c:wc_CheckProbablePrime_ex() and wolfcrypt/src/pwdbased.c:wc_PKCS12_PBKDF_ex();
add WARN_UNUSED_RESULT macro to types.h;
text format cleanup;
fix internal.c:LowResTimer() implementation.
refactor tls13.c:TimeNowInMilliseconds() for kernel 4.9 and 3.16 compat.
use ktime_get_coarse_real_ts64() only for kernel 5.x+. in kernel 4.x, use its older form, current_kernel_time64(), and in 3.x, use getnstimeofday().
linuxkm/module_hooks.c: fix wolfssl_init() pie code to be compatible with kernel 4.4-;
fix allocate_wolfcrypt_irq_fpu_states() return codes to all be wolfcrypt codes, and in calling code, pass up that code (suggested by dgarske peer review).
add build-time support for module signing using native Linux facility;
add support for alternative licenses using WOLFSSL_LICENSE macro;
improve load-time kernel log messages;
add support for sp-math-all asm/AVX2 acceleration;
add error-checking and return in SAVE_VECTOR_REGISTERS();
implement support for x86 accelerated crypto from interrupt handlers, gated on WOLFSSL_LINUXKM_SIMD_X86_IRQ_ALLOWED:
* wolfcrypt_irq_fpu_states
* am_in_hard_interrupt_handler()
* allocate_wolfcrypt_irq_fpu_states()
* free_wolfcrypt_irq_fpu_states()
* save_vector_registers_x86()
* restore_vector_registers_x86()
add WOLFSSL_LINUXKM_SIMD, WOLFSSL_LINUXKM_SIMD_X86, and WOLFSSL_LINUXKM_SIMD_ARM macros for more readable gating.
