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.
* 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;
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).
Regenerate the SP backends so the ECDH secret generators check the caller's
buffer against the number of bytes actually written. Adds a P-384/P-521
buffer-size regression test.
Zeroization:
- Add missing ForceZero on the PRF outputs and WOTS+ chain state that hold
secret key material.
- Route the WOTS sign leaf through a temp so secret chain values never touch
the public signature buffer.
- Add SLHDSA_SHAKE_X4_STATE_W so buffer and wipe sizes stay in sync.
Leak / alloc-failure fixes:
- Fix chain_idx_x4 returning on SAVE_VECTOR_REGISTERS2 failure without freeing
state/fixed (memory leak, and the secret was left unzeroized); break to the
cleanup path instead.
- Guard all function-scope wipes with WC_VAR_OK to avoid a NULL deref when an
allocation fails under WOLFSSL_SMALL_STACK.
Return PUBLIC_KEY_E for wc_ed25519_export_key if public key is not
present.
Return PUBLIC_KEY_E for wc_ed448_export_key if public key is not
present.
Rename several inLen parameters to outLen for consistency.
Fix F-4427
wolfcrypt/src/aes.c: enforce AES-XTS K1!=K2 constraint in wc_AesXtsSetKeyNoInit() unless WC_AES_XTS_ALLOW_DUPLICATE_KEYS and !HAVE_FIPS:
tests/api/test_aes.c: add negative tests to test_wc_AesXtsSetKey() for K1==K2;
wolfcrypt/test/test.c: fix keys in aes_xts_128_inplace_test() and aes_xts_192_inplace_test() so that K1!=K2, update test vectors, and remove associated !HAVE_FIPS gating;
linuxkm/lkcapi_aes_glue.c: synchronize aes_xts_128_test() test of ciphertext stealing in-place with wolfcrypt/test/test.c.
wrapper/rust/wolfssl-wolfcrypt/src/aes.rs: synchronize XTS streaming test with wolfcrypt/test/test.c.
linuxkm/: refactor self-test sensing with version-gated setup in linuxkm_wc_port.h and refactored gates in lkcapi_glue.c.
crl.c, internal.h: leak of sigParams requiring reorder the struct fields to that it is above memcpy part.
dtl13.c: free the DRLS fragments buffer in Dtls13FreeFsmResources in case fragment is never sent.
ocsp.c: only free cid if locally allocated.
tls.c: make sure ecc_kse is zeroized and can be freed.
tls13.c: set hsHashesEch after init so isn't lost on failure.
evp_pk.c: free key on the BIO error path
Fixed various tests to not leak or crash on memory allocation failure.
MAX_ENCODED_SIG_SZ grows to ~50KB once SLH-DSA is enabled, yet it was
used to size PKCS#1/signature scratch and output buffers across the
library, wasting stack and heap even for classic RSA/ECC operations.
- Add MAX_ENCODED_CLASSIC_SIG_SZ for RSA/DSA/ECC DigestInfo buffers that
can never hold a PQC signature.
- Size the certificate/CSR signing output buffer from the signing key at
runtime instead of the worst-case macro.
- Add overridable WOLFSSL_MAX_SIG_SZ for the WOLFSSL_NO_MALLOC buffer.
- Reject a signature type that does not match the signing key.
Extend wc_MakeCert_ex/wc_SignCert_ex/wc_MakeCertReq_ex to issue HSS/LMS and
XMSS/XMSS^MT certificates and PKCS#10 requests, building on the existing
RFC 9802 verification support. New LMS_TYPE/XMSS_TYPE/XMSSMT_TYPE selectors,
wc_{Lms,Xmss}Key_PublicKeyToDer SPKI encoders, runtime signature-buffer
sizing, and sigType/key consistency checks. Generation is ASN.1-template
only, matching where the verification path lives.
Tests generate self-signed roots, CSRs and a CA->ECC-leaf chain in-process
and verify them, replacing the patched Bouncy Castle fixtures (only the stock
RFC 9802-aligned LMS interop anchor is kept).
