test_wc_falcon_sign_verify aborted (SIGABRT) when run as part of the
full unit suite in liboqs configs. The direct OQS_SIG_keypair() call
draws from liboqs' randombytes callback, which wolfSSL points at its
default liboqs RNG; wolfSSL_liboqsClose() (run by wolfCrypt_Cleanup)
frees that RNG without resetting liboqs_init, so after any earlier
Init/Cleanup cycle in the suite the re-Init never re-creates it and
the callback abort()s on the freed RNG. Running the test alone passed,
which is why this only surfaced in make check.
Drop the direct liboqs usage entirely: decode the embedded
bench_falcon_level1_key (certs_test.h) with wc_Falcon_PrivateKeyDecode
and exercise sign/verify through the wolfSSL API only, which hands the
test's own RNG to liboqs and does not depend on the default-RNG
lifecycle. Also removes the oqs/oqs.h include and the OQS_STATUS
handling; with no liboqs symbols left in the body, only the guard
still references HAVE_LIBOQS, easing the planned liboqs removal.
Validated in --with-liboqs --enable-experimental --enable-falcon (the
failing PRB-liboqs config): the full unit suite now completes with the
test passing at the position that aborted; also passes under
opensslall+falcon and compiles clean with -Werror=bad-function-cast.
ExpectIntEQ casts both arguments to int (tests/unit.h ExpectInt), and
casting a function call that returns the liboqs OQS_STATUS enum trips
-Werror=bad-function-cast, which is part of the test warning set. Store
the status in a local first; casting a variable does not trigger the
warning. Broke falcon-enabled configs once the HAVE_PQC guard fix made
this test compile.
Verified: the TU reproduces the exact CI error before this change and
compiles clean after, and test_wc_falcon_sign_verify still passes in a
--disable-md5 --enable-opensslextra --enable-falcon --with-liboqs
build.
Address the PR 10845 review findings:
* test_signature.c: the Falcon sign/verify test was guarded on
HAVE_PQC, which no build system ever defines (--enable-falcon sets
HAVE_FALCON only), so the test always compiled out to skipped. Gate
it on HAVE_FALCON && HAVE_LIBOQS like the library does, and drop the
now-unreferenced HAVE_PQC entry from .wolfssl_known_macro_extras.
Verified with --enable-opensslall --enable-experimental
--enable-falcon --with-liboqs: the test now executes and passes.
* api.c: revert the (OPENSSL_EXTRA || OPENSSL_ALL) widening of the
inner guards of test_wolfSSL_TXT_DB and the new
test_wolfSSL_NCONF_negative_paths. Both functions live inside the
enclosing OPENSSL_ALL block and their TEST_DECLs are OPENSSL_ALL-
gated (and TXT_DB/NCONF themselves are OPENSSL_ALL-only APIs), so
the widening could never take effect. Inner guards now match their
siblings (filesystem/BIO deps only).
* test_pkcs12.c: wrap the expected BAD_FUNC_ARG values of the new
parse guardrail asserts in WC_NO_ERR_TRACE() for consistency with
the rest of the PR's negative-path assertions.
All six affected tests pass in an opensslall+falcon+liboqs build:
falcon_sign_verify, TXT_DB, NCONF, NCONF_negative_paths,
PKCS12_parse_guardrails, PKCS12_create_guardrails.
PRB-generic-config-parser failed in test_wolfSSL_X509V3_EXT under an
OPENSSL_EXTRA (non-OPENSSL_ALL) config:
test_ossl_x509_ext.c:1519 ExpectIntEQ(actual, 0) /* got -5 */
The function walks the OCSP root CA's extensions by hardcoded index (i=0 basic
constraints, i=1 subject key id, i=2 authority key id, ...) and asserts fixed
values. The strcmp result -5 is exactly '2'-'7': the i=1 i2s produced the
authority-key-id value ("27:8E:...") instead of the subject-key-id
("73:B0:..."), i.e. the stored-extension order differs in OPENSSL_EXTRA-only
builds, so the index assumption breaks.
On master this test is gated on OPENSSL_ALL; the MC/DC campaign commit
(bc92090b3) over-widened it to (OPENSSL_EXTRA || OPENSSL_ALL) when splitting
api.c. Revert just this function's guard to OPENSSL_ALL. The by-NID
test_wolfSSL_X509V3_EXT_aia above keeps its OPENSSL_EXTRA widening (that is the
one the AIA leak fix needed, and it looks extensions up by NID so it is
order-independent).
Verified: skipped under --enable-opensslextra (no longer runs/fails there),
runs and passes under --enable-all.
test_wc_RsaDecisionCoverage decrypted an OAEP-SHA256 cipher text as PKCS#1 v1.5
and asserted it must return < 0. That is flaky: v1.5 decrypt-unpadding of the
random OAEP plaintext spuriously "succeeds" whenever byte[1] lands on 0x02 with
a valid 0x00 separator after >=8 nonzero bytes -- a few-percent-per-run coin
flip, and a fresh random key is generated each run. It surfaced as intermittent
make-check failures (e.g. "result: 36 >= 0", "140 >= 0") on PR CI.
Replace it with a deterministic padding-mismatch: decrypt the (no-label) OAEP
cipher text as OAEP with a non-empty label. OAEP authenticates the label via
lHash, so a label mismatch fails the integrity check every time, still
exercising the padding-mismatch decision branch in rsa.c.
Verified locally by looping test_wc_RsaDecisionCoverage 150x in an
OAEP+SHA256 build: old assertion failed 2/150, new assertion 0/150.
PRB-fips-repo-and-harness-test-v3-part1 (FIPS v2, --enable-fips=v2
--enable-opensslextra/--enable-opensslall) failed in test_wc_AesFeatureCoverage.
Reproduced against a real FIPS v2 build (linuxv2 = WCv4-stable module, in-core
integrity hash regenerated)
The PRB-CAVP-selftest-v2 leg (--enable-selftest=v2, frozen wolfCrypt 4.1.0
crypto) failed in test_wc_AesFeatureCoverage.
Reproduced against that exact build; the failing assertion is:
tests/api/test_aes.c:8324
ExpectIntEQ(wc_AesCcmEncrypt(&aes, NULL, NULL, 0, ccmNonce13,
sizeof(ccmNonce13), ccmTag, 16, ccmAad, sizeof(ccmAad)), 0) /* got -173 */
That is the AAD-only (empty-plaintext) CCM case. Current wolfCrypt accepts
NULL in/out when inSz==0; the frozen v4.1.0 wc_AesCcmEncrypt rejects in/out==NULL
unconditionally and returns BAD_FUNC_ARG. Same class as the RsaDecisionCoverage
self-test fix: the frozen module's argument-validation contract predates the
modern behaviour this test asserts.
This function's value is MC/DC of the open wolfcrypt/src/aes.c feature paths,
which is not the aes.c compiled under --enable-selftest, so under self-test it
measures nothing and only risks such divergences. The key-wrap block in this
same function already excludes HAVE_SELFTEST (and the AES *ArgMcdc tests do
too); extend that to the GCM/GMAC and CCM blocks. HAVE_FIPS is intentionally
left running -- that (newer) module honours these paths and never flagged this
test; the open MC/DC campaign builds are unaffected.
Verified: skipped cleanly under --enable-selftest=v2 (test index 278, matching
CI); open build still runs and passes it.
The PRB-CAVP-selftest-v2 leg (./configure --enable-selftest=v2, which overlays
frozen wolfCrypt 4.1.0 crypto) failed in test_wc_RsaDecisionCoverage.
Reproduced against that exact build; the failing assertion is:
tests/api/test_rsa.c:1474
ExpectIntEQ(wc_RsaSetRNG(&key, NULL), BAD_FUNC_ARG) /* got 0 */
So the assertion is correct for current wolfCrypt but not part of the frozen
self-test module's contract. This test's whole purpose is MC/DC of the *open*
wolfcrypt/src/rsa.c decision branches, which is not even the rsa.c compiled
under --enable-selftest, so under self-test it measures nothing and only risks
divergent error codes like this one. The sibling key-gen/decision tests in this
file (test_wc_CheckProbablePrime, the RsaKeyGeneration group) exclude
HAVE_SELFTEST for the same reason; do so here too.
Guard the whole function rather than the single assertion: none of it counts
toward the (open-build) MC/DC campaign under self-test, and a whole-function
guard is robust against any other frozen-vs-current divergence in the same
body. HAVE_FIPS is intentionally left running -- that (newer) module honours
these decisions (and excludes the WC_RSA_BLINDING wc_RsaSetRNG block anyway),
and the open MC/DC campaign builds are unaffected.
Verified: with the guard, the test is cleanly skipped under --enable-selftest=v2
(test index 365, matching CI); the open build still runs and passes it.
A second apple-M1 FIPS segfault (--enable-fips=v5): test_wc_AesCcmArgMcdc probes
the pure-C CCM inSz-overflow decision by calling wc_AesCcmEncrypt/Decrypt with a
1-byte dummy in/out buffer and a claimed length of 65536, relying on the pure-C
path returning AES_CCM_OVERFLOW_E *before* touching the buffer. The FIPS module's
CCM does not reject early, so it writes 65536 bytes into the 1-byte buffer and
segfaults. (The rounds=0 corruption in the same test was already skipped via
WC_TEST_AES_ROUNDS_OFFLOADED, but the two overflow blocks were not.)
Every decision this test targets lives in pure-C aes.c CCM code that is not
compiled in FIPS/self-test builds, so guard the whole function on
!defined(HAVE_FIPS) && !defined(HAVE_SELFTEST) rather than patching each unsafe
block. The other *ArgMcdc tests only corrupt rounds (macro-skipped) and have no
oversized-buffer calls, so they need no further change.
Verified: --enable-all still builds and test_wc_AesCcmArgMcdc passes; the 65536
overflow calls are present non-FIPS and absent when HAVE_FIPS is defined.
The CAVP self-test build (--enable-selftest) failed to compile test_aes.c:
wc_AesGcmSetExtIV (test_wc_AesGcmDecisionCoverage) and wc_Gmac/wc_GmacVerify
(test_wc_AesGmacArgMcdc) are declared only under !WC_NO_RNG in mainline and are
absent from the frozen self-test module's headers (they are present under FIPS -
the apple-M1 FIPS build compiled and passed both), so -Werror=implicit-function-
declaration aborted the build.
Gate those specific calls (and the now-otherwise-unused iv buffer) on
!defined(WC_NO_RNG) && !defined(HAVE_SELFTEST). wc_GmacSetKey stays available, so
its coverage is retained under self-test. FIPS builds are unaffected.
Verified: --enable-all still builds and both tests pass; preprocessing test_aes.c
with -DHAVE_SELFTEST leaves no wc_AesGcmSetExtIV/wc_Gmac/wc_GmacVerify calls in
any always-compiled function (remaining ones are in the WOLFSSL_AESGCM_STREAM
stream test, which the self-test config disables).
test_wc_AesCcmArgMcdc segfaulted on the FIPS builds (apple-M1 config A, CAVP
self-test), exit 139. The AES *ArgMcdc tests reach the post-key-setup "ret != 0"
checkpoints by corrupting aes->rounds = 0 and calling wc_AesCcmEncrypt/Decrypt.
That relies on the pure-C AesEncryptBlocks_C guard (if r==0 return KEYUSAGE_E) to
turn the corruption into a clean error return. Under the FIPS / self-test module
the AES implementation has no such guard, so rounds=0 runs AES with a zero-round
key schedule and dereferences past the key schedule -> SIGSEGV.
The corruption is already gated by WC_TEST_AES_ROUNDS_OFFLOADED (crypto-cb / asm
offload). FIPS and self-test are the same situation - the pure-C guard is not in
the compiled path - so add HAVE_FIPS / HAVE_SELFTEST to that macro. The three
function-level FIPS-guarded tests (SetKey/Modes/Cmac ArgMcdc) were already
skipped; test_wc_AesCcmArgMcdc is not, and its non-corruption CCM coverage now
still runs under FIPS while only the rounds-corruption blocks are skipped.
Verified: --enable-all (non-FIPS) still runs and passes all rounds-corruption
tests; the corruption blocks compile out only under FIPS/self-test.
This branch widened test_wolfSSL_X509V3_EXT's guard from OPENSSL_ALL to
(OPENSSL_EXTRA || OPENSSL_ALL). The Authority Info Access sub-test frees its
aia stack with wolfSSL_sk_ACCESS_DESCRIPTION_pop_free(aia, NULL), relying on the
stack's type-based element free - but wolfssl_sk_get_free_func() only wires up
wolfSSL_ACCESS_DESCRIPTION_free for STACK_TYPE_ACCESS_DESCRIPTION under
OPENSSL_ALL. In an OPENSSL_EXTRA-only build (now reachable) the NULL callback
frees the stack nodes but leaks each ACCESS_DESCRIPTION (struct + method OBJ +
location GENERAL_NAME + URI string): 370 bytes, caught by ASAN/valgrind.
Pass wolfSSL_ACCESS_DESCRIPTION_free explicitly (available under OPENSSL_EXTRA);
correct under OPENSSL_ALL too. Verified leak-free under ASAN with the failing
config (--enable-opensslextra --enable-crl ... --disable-fastmath).
clang-tidy (all-c89, async-quic, intelasm) flagged `ccmTag[0] ^= 0x01` as a use
of an uninitialized value: the analyzer does not model wc_AesCcmEncrypt writing
the tag buffer. Zero-initialize ccmTag; the subsequent encrypt still overwrites
it before the tamper, so behavior is unchanged.
Same FIPS-header mismatch as the earlier AesSetKey/Cmac guard: the FIPS v2/v5
modules lack AES_IV_FIXED_SZ and GCM_NONCE_MIN/MID/MAX_SZ and declare
wc_AesEncryptDirect as void, so test_wc_AesModesArgMcdc and test_wc_AesGcmArgMcdc
fail to compile there (fatal under -Werror). Gate both on the modern API with
the same idiom used by the other AES-DIRECT tests.
The apple-m1 "known config A" (FIPS) build broke: the FIPS module's frozen
headers declare wc_AesEncryptDirect/wc_AesDecryptDirect as void (not int) and
omit wc_CmacFree, so the new tests' ExpectIntEQ(wc_AesEncryptDirect(...)) and
wc_CmacFree() usages don't compile.
Gate test_wc_AesSetKeyArgMcdc and test_wc_AesCmacArgMcdc on the modern API with
the same idiom test_wc_AesEncryptDecryptDirect_WithKey already uses:
(!defined(HAVE_FIPS) || !defined(HAVE_FIPS_VERSION) || (HAVE_FIPS_VERSION > 6))
&& !defined(HAVE_SELFTEST)
The campaign runs non-FIPS, so no coverage is lost where it is measured.
Verified: --enable-all still builds and both tests run.
The last two red PR jobs, both in the branch's new tests:
- intelasm (ASAN): test_wc_AesKeyExportArgMcdc calls wc_AesInit_Id() and
wc_AesInit_Label() which succeed (allocating the WC_DEBUG_CIPHER_LIFECYCLE
tag) but were never freed -> 8-byte LeakSanitizer leak. Add wc_AesFree()
to both blocks.
- no-client-no-client-auth (minimal server-only build):
test_wolfSSL_session_cache_api_direct's wolfSSL_new() returned NULL because
a certless server CTX has no usable cipher suite. Load the test server
cert/key (file, with a USE_CERT_BUFFERS_2048 fallback) before wolfSSL_new()
in the server-only path; the client path is cert-free as before.
Verified: --enable-all + ASAN run of the aes group is leak-free, and
CPPFLAGS="-DNO_WOLFSSL_CLIENT -DWOLFSSL_NO_CLIENT_AUTH" now passes.
The aes.rounds-validity check that returns KEYUSAGE_E lives only in the
pure-C block encrypt (AesEncryptBlocks_C). On ARMv8 with crypto extensions,
--enable-all auto-enables WOLFSSL_ARMASM, whose asm wc_AesEncrypt bypasses
that check, so corrupting aes.rounds no longer fails the op (returns 0).
This broke the SetKey/CTR/CFB/OFB/CCM/CMAC rounds-corruption assertions on
the arm64 CI runners.
Extend WC_TEST_AES_ROUNDS_OFFLOADED to also cover WOLFSSL_ARMASM (joining
WOLF_CRYPTO_CB_FIND / WOLF_CRYPTO_CB_ONLY_AES). MC/DC of that decision is
still obtained from the pure-C configs in the variant union. x86 (incl.
AES-NI, which does validate rounds) is unaffected.
Three more failures in the branch's added tests, found via the ASAN, C++
and no-client CI configs:
- test_wolfSSL_X509V3_EXT leaked 2296 bytes: the added
X509_get_ext_d2i(x509, NID, &critical, NULL) calls (used to exercise the
critical-flag output) discarded their allocated result. Free each per its
actual return type: BASIC_CONSTRAINTS, ASN1_STRING (key usage),
AUTHORITY_KEYID, AUTHORITY_INFO_ACCESS, and - for subject_key_identifier -
a STACK_OF(ASN1_OBJECT) (wolfSSL_X509_get_ext_d2i wraps a lone obj in a
stack). This was the real cause of the sanitize-asan / intelasm / krb-asan
job failures (the read_write_ex/ECH/dtls13 asserts printed there are
retry-masked and fail identically on master).
- C++ build (all-pq-cxx): void* from X509_get_ext_d2i does not implicitly
convert; add explicit WOLFSSL_X509_EXTENSION* casts.
- no-client link (all-no-client): wolfSSL[_CTX]_UseOCSPStapling[V2] (CSR/CSR2)
are client-side APIs; guard those blocks with !NO_WOLFSSL_CLIENT.
Verified: full --enable-all + ASAN run is leak-free and passes; --enable-all
-DNO_WOLFSSL_CLIENT builds and links.
Three more config-matrix failures in the AES coverage tests:
- Rounds-corruption checks (aes.rounds/cmac.aes.rounds = 0/17 -> expect
KEYUSAGE_E) also break under WOLF_CRYPTO_CB_ONLY_AES, which strips the
software AES so the op is serviced by the callback and ignores the
corrupted struct (same net effect as WOLF_CRYPTO_CB_FIND). Introduce
WC_TEST_AES_ROUNDS_OFFLOADED = (WOLF_CRYPTO_CB_FIND || _ONLY_AES), replace
the previous WOLF_CRYPTO_CB_FIND-only guards with it, and extend it to the
wc_AesEncryptDirect/wc_AesDecryptDirect checks in AesSetKeyArgMcdc (which
the ONLY_AES path also offloads).
- test_wc_AesFeatureCoverage's GCM-streaming block uses a hardcoded 256-bit
key; guard it with WOLFSSL_AES_256 (failed under -DNO_AES_256).
- Its AES-KeyWrap block uses a 192-bit key; guard with WOLFSSL_AES_192
(failed under -DNO_AES_192).
Verified: --enable-swdev --enable-cryptocb ... -DWOLF_CRYPTO_CB_ONLY_AES and
--enable-all -DNO_AES_192 -DNO_AES_256 now both build and pass; a normal
--enable-all build still runs the rounds checks.
Several AES ArgMcdc tests corrupt aes.rounds (or cmac.aes.rounds) and
expect the subsequent op to fail with KEYUSAGE_E from the in-process
software AES path. Under WOLF_CRYPTO_CB_FIND (e.g. --enable-swdev), the
"devId != INVALID_DEVID" guard is removed, so CTR/CCM/CMAC ops are
offloaded to the registered crypto callback even for INVALID_DEVID; the
callback re-derives the key and ignores the corrupted struct, returning 0
instead of KEYUSAGE_E and failing the assertion.
Guard those internal-failure checks with #ifndef WOLF_CRYPTO_CB_FIND
(wc_AesCtrEncrypt, wc_AesCfb/OfbEncrypt/Decrypt, wc_AesCcmEncrypt/Decrypt,
wc_CmacUpdate); the raw-block wc_AesEncryptDirect path in SetKey does not
route through cryptocb, so it stays. (void)-cast the locals only used by
the guarded checks to keep -Werror clean. MC/DC is unioned across configs,
so no union coverage is lost.
Verified: --enable-swdev ... (WOLF_CRYPTO_CB_FIND) now passes, and a
non-CB_FIND build with all these modes still runs and passes the checks.
The check-source-text CI job flags non-ASCII (8-bit) bytes in source. The
new MC/DC tests and README used UTF-8 punctuation in comments/prose
(em-dash, ellipsis, left-right arrow). Replace with ASCII equivalents
(-, ..., <->). Verified: ./.github/scripts/check-source-text.sh on the
changed files reports clean.
The new MC/DC coverage tests broke many CI configs under -Werror (which is
auto-enabled for in-git-tree builds). Fixes, each verified with a real
-Werror build of the relevant config:
- test_aes.c: wrap the whole test_wc_AesSivArgMcdc definition in
WOLFSSL_AES_SIV && WOLFSSL_AES_128 (was body-only guarded while its
prototype is guarded) -> fixes -Wmissing-prototypes when SIV is off.
- test_aes.c: mark key/in/out (void) in test_wc_AesModesArgMcdc; they are
used only by the per-mode (CTR/CFB/OFB) blocks -> fixes -Wunused-variable
when no such mode is enabled.
- api.c: guard the test_CryptoCb_* callback helpers with
WOLF_CRYPTO_CB && WOLFSSL_TEST_STATIC_BUILD to match their only caller
-> fixes -Wunused-function in cryptocb non-static builds.
- api.c: register test_wc_CryptoCb_registry under its actual definition
condition (WOLF_CRYPTO_CB && HAVE_IO_TESTS_DEPENDENCIES && !ONLY_*) and
keep test_wc_CryptoCb registered unconditionally (as on master)
-> fixes undeclared / defined-but-unused across cryptocb configs.
- api.c: declare session-cache 'mode' under OPENSSL_EXTRA (its only uses)
-> fixes -Wunused-variable without opensslextra.
- api.c: guard the Enable/DisableOCSPStapling calls in
test_wolfSSL_crl_ocsp_object_api with HAVE_CERTIFICATE_STATUS_REQUEST[_V2]
-> fixes undefined references with OCSP but no stapling.
Verified clean under: --enable-ocsp --enable-ocspstapling, --enable-ocsp
(no stapling), and --enable-all; unit.test runs pass.
test_wc_AesModesArgMcdc asserted that wc_AesCtrEncrypt() with corrupted
aes.rounds returns KEYUSAGE_E, but used sz = 32 (an exact block multiple).
When in != out, the full blocks are consumed by a batch path that does not
surface the per-block rounds error - the AES-NI batch, or the HAVE_AES_ECB
fast path which ignores wc_AesEcbEncrypt()'s return - leaving no trailing
partial block, so the function returns 0 and the assertion fails. This was
latent (the whole test binary failed to link before the visibility fix) and
reproduces in --disable-aesni --enable-aesecb builds.
Use a non-block-multiple size (WC_AES_BLOCK_SIZE + 4) so the
"(ret == 0) && sz" leftover-handling call runs and fails on the corrupted
rounds via wc_AesEncrypt() in every backend. Reported by Copilot review on
PR #10845.
Verified: test_wc_AesModesArgMcdc now passes under --disable-aesni
--enable-aesecb (previously failed) and under --enable-aesni --enable-aesecb.
Several MC/DC coverage tests called WOLFSSL_LOCAL (hidden-visibility)
library functions directly from the in-tree unit.test:
- wc_AesCcmCheckTagSize() (test_aes.c)
- wc_CryptoCb_Init/Cleanup/GetDevIdAtIndex() (api.c)
These only link when the library is built with test-static visibility, so
normal (shared) builds failed at link with "undefined reference", breaking
essentially every CI build job. Gate the affected assertions on
WOLFSSL_TEST_STATIC_BUILD (in addition to the existing feature guards) so
they compile out where the symbols are hidden, matching the existing
wolfSSL convention for internal-symbol tests.
Verified: ./configure --enable-all (no WOLFSSL_TEST_STATIC_BUILD) now
builds tests/unit.test cleanly and the full suite passes.
Add tests/unit-mcdc/, a standalone white-box program that compiles
wolfcrypt/src/aes.c directly to reach static/WOLFSSL_LOCAL helpers
(GHASH/GHASH_UPDATE ptr guards, _AesNew_common cross-arg checks) that
are structurally unreachable through the public API, closing 19 of the
AES MC/DC residuals. Extend tests/api/test_aes.{c,h} with the
decision/feature coverage cases these build on.
These are for the external ISO 26262 per-module MC/DC campaign; they do
not change library behaviour and are not part of the wolfSSL build.
- Break out of the chain-build loop after the partial-chain fallback accepts
a caller-trusted terminus, so it is pushed to ctx->chain once instead of
twice; X509StoreCheckPathLen's anchor-skip is now defensive, not load-bearing.
- Drop the now-dead cert == anchor guard and refresh the comment.
- Rework the pathLen regression tests: reuse the existing certs/test-pathlen
chains (chainF rejects, chainB verifies) instead of inlined report certs.
tests/api/api.h: always use FIPS 186-4 settings if defined(HAVE_SELFTEST).
wolfssl/wolfcrypt/settings.h: if defined(HAVE_SELFTEST), #define WC_FIPS_186_4.
* remove FIPS 186-5 sign-mode restrictions from WC_HASH_CUSTOM_MIN_DIGEST_SIZE.
* set up WC_MIN_DIGEST_SIZE_FOR_SIGN and WC_MIN_DIGEST_SIZE_FOR_VERIFY, derived from WC_HASH_CUSTOM_MIN_DIGEST_SIZE, but enforcing FIPS 186-5 sign-mode restrictions only for WC_MIN_DIGEST_SIZE_FOR_SIGN.
* replace all uses of WC_MIN_DIGEST_SIZE with WC_MIN_DIGEST_SIZE_FOR_SIGN or WC_MIN_DIGEST_SIZE_FOR_VERIFY as appropriate.
