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.
Only exempt the missing-certificate check during the initial handshake; once a
post-handshake CertificateRequest is outstanding the server again requires the
client certificate (and its CertificateVerify). Adds a post-handshake auth
test.
Ensure a peer's certificate form (X.509 vs raw public key) matches the
negotiated certificate type, defaulting to X.509 when none was negotiated,
on both the client and server. Adds RPK regression tests covering both
directions.
Require the keyCertSign key usage on non-root intermediate CAs added during
path building when a KeyUsage extension is present, per RFC 5280. Adds a
regression test.
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
Robustness fixes in the OpenSSL-compatibility certificate verifier, independent
of the depth-exhaustion fix:
- Fail closed on allocation failure. When the failedCerts working stack could
not be allocated, the function fell through to exit with ret still set to
WOLFSSL_SUCCESS and reported the chain as verified without checking anything
(a fail-open regression from the leak fix that turned the early return into a
goto exit). Also check the ctx->chain allocation. Both now set an error.
- Remove caller-supplied intermediates from the correct stack. The intermediates
appended to the working cert list during chain building were popped from
ctx->store->certs by count, but they are appended to whichever stack is in use
- which may be the caller's setTrustedSk (X509_STORE_CTX_set0_trusted_stack).
Remove them by pointer identity from that same stack, recomputed from
ctxIntermediates. Identity removal also survives the chain-building retries
that reorder the stack, where a positional pop could drop a legitimate trusted
entry and leave an injected intermediate behind - which a later verification
reusing the store/ctx would then snapshot as a trust anchor. The removal helper
walks the list once (O(n)) rather than indexing per position.
- NULL-guard ctx->store->param before dereferencing its flags in the
partial-chain check.
Add regression tests covering: the trusted stack being restored after
verification, and the retry path (tampered plus genuine same-subject
intermediates, both orderings) leaving the store clean for later use.
Fail compatibility-layer verification when the path-building loop runs
out of its depth budget before reaching a configured trust anchor,
instead of accepting the last verified link. Add a regression test.
Ensure caller-supplied intermediate certificates cannot terminate the
chain during compatibility-layer verification; a path must reach a
configured trust anchor. Add a regression test and supporting certs.
wolfcrypt/src/aes.c: enforce AES-XTS K1!=K2 constraint in wc_AesXtsSetKeyNoInit() unless WC_AES_XTS_ALLOW_DUPLICATE_KEYS and !HAVE_FIPS:

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.
The client's resumed-session EMS (F-5807) and cipher-suite (F-5811) checks
were enforced in CompleteServerHello at ServerHello-parse time. For stateless
ticket resumption the client sends an empty session ID and cannot yet tell
whether the server accepted the ticket (RFC 5077 3.4): a server that declines
the ticket falls back to a full handshake under a freshly negotiated
suite/EMS state, which these checks wrongly aborted with MATCH_SUITE_ERROR,
breaking the RFC 5077 ticket-decline fallback to a full handshake.
Move both checks into CheckResumptionConsistency and run it only once
resumption is confirmed - from whichever the server sends first in the
abbreviated flight: a renewed NewSessionTicket (before SetupSession refreshes
the cached suite/EMS to the current values) or its ChangeCipherSpec. By then
the "Not resuming as thought" path has cleared 'resuming' for any ticket
decline, so the full-handshake fallback proceeds.
Add test_tls12_resume_ticket_decline_fallback (ticket declined by a fresh
server CTX, full handshake under a different suite must succeed) and gate
test_tls12_resume_ticket_wrong_suite on WOLFSSL_NO_DEF_TICKET_ENC_CB so it
skips rather than fails in builds without the default ticket encryption
callback.
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.
Address review on PR #10582:
- The client-side extended_master_secret consistency check skipped all
session-ticket resumptions, leaving a generic ticket resumption open to
an undetected EMS downgrade by a malicious server or MITM. The client
retains the EMS state for ticket sessions too (SetupSession), so the
check now applies to ticket resumption as well, mirroring the adjacent
cipher-suite check. Only EAP-FAST style resumption - where the
session-secret callback supplies the master secret for an opaque PAC
ticket - is exempt, matched precisely via ssl->sessionSecretCb just as
the callback invocation in DoServerHello does.
- Add test_tls_ems_resumption_server_downgrade, exercising the
client-direction downgrade (server resumes but omits EMS from its
ServerHello) for both session-ID and session-ticket resumption. This
client-side branch previously had no test coverage.
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).
