tests/api.c: add error_test() adapted from wolfcrypt/test/test.c, checking all error strings for expected presence/absence and length, called from existing test_wolfSSL_ERR_strings().
wolfssl/ssl.h, wolfssl/error-ssl.h, and wolfssl/wolfcrypt/error-crypt.h:
* move several negative error return codes from ssl.h to error-ssl.h,
* renumber them to conform to existing sequence, and
* include error-ssl.h from ssl.h;
* add special-case WOLFSSL_DEBUG_TRACE_ERROR_CODES macros for WOLFSSL_FAILURE;
* add missing WOLFSSL_API attribute to wc_backtrace_render().
add numerous WC_NO_ERR_TRACE()s to operand error code uses, cleaning up error traces in general, and particularly when WOLFSSL_DEBUG_TRACE_ERROR_CODES_ALWAYS.
* crypto lib (36),
* crypto test&benchmark (20),
* TLS lib (179),
* examples (122),
* linuxkm (3),
* tests/api.c (2272).
wolfssl/wolfcrypt/error-crypt.h: add WC_FIRST_E.
wolfcrypt/src/error.c: add MP error code strings.
wolfssl/error-ssl.h: add WOLFSSL_FIRST_E and WOLFSSL_LAST_E.
wolfcrypt/test/test.c: update error_test() for new error code layout, refactoring the "missing" check.
src/internal.c: use WC_FIRST_E and WC_LAST_E in wolfSSL_ERR_reason_error_string().
src/ssl.c: fix wolfSSL_ERR_GET_REASON() to identify in-range error codes using WC_FIRST_E, WC_LAST_E, WOLFSSL_FIRST_E, and WOLFSSL_LAST_E.
sp_int.h: provide for WOLFSSL_DEBUG_TRACE_ERROR_CODES, and refactor MP error codes as enums, for consistency with other error codes.
wolfcrypt/src/ecc.c: fix 2 identicalInnerCondition's.
* ecc.c: in wc_ecc_free(), fix gating around handling for key->sign_k to resolve memory leak, and in wc_ecc_gen_deterministic_k(), fix -Wconversion.
* test.c: add missing mp_free()s to ecdsa_test_deterministic_k_rs() and ecc521_test_deterministic_k().
* wc_HashType: change several occurrences of int to enum wc_HashType, including ecc_key.hashType and API wc_ecc_set_deterministic_ex(), to resolve C++ warnings.
* fixes for various C++ warnings/errors in crypto and TLS layers and test and benchmark code -- implicit casts, negative initializers for unsigned type, jumped initializers, and missing enums in switch()es.
* add support for DEBUG_LINUXKM_FORTIFY_OVERLAY to allow KASAN analysis of the overlay without actually enabling CONFIG_FORTIFY_SOURCE (which is buggy in combination with KASAN).
* make SAVE_VECTOR_REGISTERS2 definition conditional on !defined(SAVE_VECTOR_REGISTERS2).
wolfssl/wolfcrypt/memory.h: fix the DEBUG_VECTOR_REGISTER_ACCESS definition for SAVE_VECTOR_REGISTERS to properly omit the on-success bookkeeping code even if the supplied fail_clause doesn't return.
wolfcrypt/src/rsa.c: in wc_MakeRsaKey() primality loop, invoke RESTORE_VECTOR_REGISTERS() SAVE_VECTOR_REGISTERS() to prevent lengthy kernel lockups.
wolfcrypt/src/dh.c: in wc_DhGenerateParams() primality loop, invoke RESTORE_VECTOR_REGISTERS() SAVE_VECTOR_REGISTERS() to prevent lengthy kernel lockups.
wolfcrypt/src/{curve25519.c,dh.c,dsa.c,ecc.c,eccsi.c,rsa.c,sakke.c,sp_int.c}: when WOLFSSL_LINUXKM, force {SAVE,RESTORE}_VECTOR_REGISTERS() to WC_DO_NOTHING if settings gate out applicable asm.
* add explanation in DoSessionTicket() re autoVariables.
* re-refactor ECC_KEY_MAX_BITS() in ecc.c to use two separate macros, ECC_KEY_MAX_BITS() with same definition as before, and ECC_KEY_MAX_BITS_NONULLCHECK().
* in rsip_vprintf() use XVSNPRINTF() not vsnprintf().
* in types.h, fix fallthrough definition of WC_INLINE macro in !NO_INLINE cascade to be WC_MAYBE_UNUSED as it is when NO_INLINE.
* fix null pointer derefs in wc_InitRsaKey_Id() and wc_InitRsaKey_Label() (nullPointerRedundantCheck).
* fix use of wrong printf variant in rsip_vprintf() (wrongPrintfScanfArgNum).
* fix wrong printf format in bench_xmss_sign_verify() (invalidPrintfArgType_sint).
* add missing WOLFSSL_XFREE_NO_NULLNESS_CHECK variants of XFREE() (WOLFSSL_LINUXKM, FREESCALE_MQX, FREESCALE_KSDK_MQX).
* suppress false-positive uninitvar on "limit" in CheckTLS13AEADSendLimit().
* suppress true-but-benign-positive autoVariables in DoClientHello().
* in wolfcrypt/src/ecc.c, refactor ECC_KEY_MAX_BITS() as a local function to resolve true-but-benign-positive identicalInnerCondition.
* refactor flow in wc_ecc_sign_hash_ex() to resolve true-but-benign-positive identicalInnerCondition.
