tests/api.c: use WOLFSSL_FILETYPE_PEM, not SSL_FILETYPE_PEM;
tests/api/test_dtls.c and tests/api/test_dtls13.c: use WOLFSSL_ERROR_WANT_READ, not SSL_ERROR_WANT_READ.
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).
ParseCipherList() only cleared the InitSuites mask for "!aNULL"/"!eNULL",
which governs generated defaults, so an explicitly listed ADH or NULL-cipher
suite survived (e.g. "ADH-AES128-SHA:!aNULL" still offered an unauthenticated
suite). Scrub the explicit suites after parsing; exclusions are order-
independent and sticky (a later "ALL" cannot re-enable them).
Add test_wolfSSL_set_cipher_list_exclusions.
Add a crypto-callback operation for validating an ECC key.
Under WOLF_CRYPTO_CB_ONLY_ECC validation now fails closed with
NO_VALID_DEVID when no device handles the operation; previously such
keys were accepted unvalidated. This is a deliberate compatibility
break, documented at the dispatch site.
Under WOLF_CRYPTO_CB_ONLY_ECC, HAVE_ECC_MAKE_PUB is now enabled and
backed by the dispatch alone, failing closed with NO_VALID_DEVID when
no device handles the operation (previously NOT_COMPILED_IN).
Instead of failing when top bit is set, the standard and current research says to mask it.
WOLFSSL_X25519_NO_MASK_PEER is added to allow the rejection when required.
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.
MatchNameConstraint() compared wildcard DNS SANs literally, so
*.example.com was not rejected by an excluded subtree covering
foo.example.com. Route WOLFSSL_GEN_DNS through
wolfssl_local_MatchDnsNameConstraint(), passing the subtree direction:
permitted subtrees require every wildcard expansion to stay inside the
subtree, excluded subtrees reject when any expansion can fall inside.
This matches what ConfirmNameConstraints() already does.
Replace ExtractHostFromUri() plus DNS-style base matching in
MatchNameConstraint() with wolfssl_local_MatchUriNameConstraint(), and
make wolfSSL_NAME_CONSTRAINTS_check_name() fail closed like
ConfirmNameConstraints(): when URI subtrees are present, a URI name
without a DNS host is rejected instead of passing excluded-only
constraints as a plain non-match.
This aligns the compat layer with RFC 5280 URI constraint semantics: a
base without a leading dot now matches the host exactly instead of as a
DNS subtree, and IP hosts no longer match at all.
Add wolfssl_local_MatchDnsNameConstraint() dispatching wildcard names
to the subtree matcher and literal names to plain base-name matching,
and use it for the ASN_DNS_TYPE branches of PermittedListOk() and
IsInExcludedList().
This also drops the outer name->len >= base len byte-length guard for
literal DNS names. That guard ran before MatchBaseName() could strip
the absolute-FQDN trailing dot, so a constraint base like
DNS:example.com. never matched the SAN example.com it denotes.
One trailing dot marks an absolute FQDN and is not part of the host:
"host.com." and "host.com" denote the same host. Strip it from the
URI host before classification (so "12.31.2.3." is still recognized
as an IPv4 address) and from the constraint base before the exact-match
comparison, mirroring what wolfssl_local_MatchBaseName() already does
for DNS name constraints. Only a single dot is the marker: an empty
last label ("host.com..") is rejected.
RFC 5280 4.2.1.10 defines URI name constraints in terms of a host that
is a fully qualified domain name; RFC 3986 IP-literal ([...]) and
IPv4address hosts are not DNS reg-names and cannot be meaningfully
matched against a DNS-style constraint base.
- Classify the host extracted by GetUriHost (IP-literal, IPv4address,
reg-name) and validate that a reg-name has no empty labels.
- wolfssl_local_MatchUriNameConstraint() no longer matches URIs whose
host is an IP address.
- ConfirmNameConstraints() fails closed: when URI constraints are
present, a URI SAN without a DNS host is rejected. A plain non-match
would otherwise let such names pass excluded-only constraints.
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.
