- x509_str: require CA:TRUE unconditionally in wolfSSL_X509_verify_cert;
verify leaf signature even when verify_cb overrides INVALID_CA
- x509_str: align WOLFSSL_X509_V_ERR_INVALID_CA with OpenSSL value (79)
so OPENSSL_COEXIST builds compile; bump WC_OSSL_V509_V_ERR_MAX to 80
and extend error_test() missing-value table for the new gaps
- asn: reject embedded NUL in dNSName / rfc822Name / URI SAN entries
- internal: re-verify restored ticket peer cert against trust store with
CRL/OCSP checks; clear stale state from session cache on verification
failure
- ticket: bind SNI and ALPN into session ticket via compile-time selected
hash (TICKET_BINDING_HASH_TYPE); reject resumption on mismatch in both
TLS 1.3 and TLS 1.2 paths
- ticket: defer SNI/ALPN binding check until after extensions are parsed
by consolidating into VerifyTicketBinding(), called once after
ALPN_Select in DoTls13ClientHello and DoClientHello; the early
per-call sites ran before extensions were parsed and rejected valid
resumptions in nginx, haproxy, grpc, and CPython integration tests
- ssl_sess: free previous session in wolfSSL_d2i_SSL_SESSION before
overwrite
- examples/client: increase SESSION_TICKET_LEN fallback from 256 to 2048
to support larger tickets
- tests: update SAN NUL fixtures and add parse-time rejection coverage;
add test_tls13_ticket_peer_cert_reverify for CA-removal scenario; skip
it under WOLFSSL_NO_DEF_TICKET_ENC_CB
Windows test code pre-picked a random port via GetRandomPort() (returning
a value in [49152, 65535]) before calling bind(), with no check that the
port was free and no retry on collision. Under load this occasionally
collided with an already-bound port and aborted the test with
"tcp bind failed", producing intermittent Jenkins failures (e.g. PRB
windows-test-v2 #17140 in the OCSP responder test).
The Unix path already does the right thing: bind to port 0 (OS-assigned
ephemeral) and read the port back via getsockname(). The same primitives
exist in Winsock 1.1, so drop the USE_WINDOWS_API guard around the
getsockname block in tcp_listen()/udp_accept() and remove the per-caller
GetRandomPort() workarounds in the OCSP responder, server example, and
the api.c / test_ossl_bio.c test sites. socklen_t is already typedef'd
as int on Windows in test.h.
GetRandomPort() itself is left in place since it is a static inline in a
shipped public test header.
RFC 8446 section 8 requires any server instance to accept 0-RTT for a
given ClientHello at most once. Prior to this change wolfSSL's behaviour
diverged from that requirement in several ways:
* ctx->maxEarlyDataSz defaulted to MAX_EARLY_DATA_SZ whenever the
library was built with WOLFSSL_EARLY_DATA, so servers auto-
advertised 0-RTT in NewSessionTicket without the application
asking. RFC 8446 E.5 says 0-RTT MUST NOT be enabled unless
specifically requested.
* The post-accept eviction is compiled out under NO_SESSION_CACHE,
so builds without the cache accepted 0-RTT with no replay defence.
* Stateless self-encrypted tickets do not carry a session ID on the
stateless DoClientTicket decrypt path, so wolfSSL_SSL_CTX_remove_
session could not locate them to evict.
* wolfSSL_SSL_CTX_remove_session always returned 0 on success
regardless of whether the session was actually in the cache,
diverging from OpenSSL's SSL_CTX_remove_session (1 on success,
0 on not-found).
Changes:
* src/internal.c: ctx->maxEarlyDataSz defaults to 0; applications
must opt in with wolfSSL_CTX_set_max_early_data.
* src/tls13.c: #error when WOLFSSL_EARLY_DATA is built with
HAVE_SESSION_TICKET and NO_SESSION_CACHE. Escape hatch
WOLFSSL_EARLY_DATA_NO_ANTI_REPLAY for deployments that take
application-layer responsibility.
* wolfssl/internal.h: imply WOLFSSL_TICKET_HAVE_ID from
WOLFSSL_EARLY_DATA so stateless-ticket issuance populates the
cache under an ID that eviction can find.
* src/ssl_sess.c: wolfSSL_SSL_CTX_remove_session returns 1 when the
session was found (internal-cache hit, or ctx->rem_sess_cb fired
for an external cache), 0 otherwise. Matches OpenSSL semantics.
* src/tls13.c: the 0-RTT acceptance condition in CheckPreSharedKeys
now calls wolfSSL_SSL_CTX_remove_session and checks its return:
the eviction is the check. If the session was in the cache, 0-RTT
is accepted and the single-use requirement is satisfied. If not,
the early_data extension is rejected through the normal path so
the record layer correctly skips in-flight 0-RTT records.
WOLFSSL_MSG at each rejection site.
* doc/dox_comments/header_files/ssl.h: document runtime opt-in.
* tests: four new tests —
test_tls13_0rtt_default_off (fails without default-to-0 fix),
test_tls13_0rtt_stateless_replay (fails without TICKET_HAVE_ID
implication and remove_session gate),
test_tls13_remove_session_return (fails without return-value fix),
test_tls13_0rtt_ext_cache_eviction (fails without ext-cache
counts-as-found fix).
test_tls13_early_data explicitly opts in via
wolfSSL_CTX_set_max_early_data.
tests/api.c: two SSL_CTX_remove_session == 0 assertions updated
to == 1.
scripts/pem.test:
* add setup for WOLFSSL_NO_DER_TO_PEM,
* exit early with skip code if executable dependencies are missing or WOLFSSL_NO_PEM or NO_CODING, and
* add clean skip clauses to convert_to_pem(), compare_pem(), and pem_der_exp(), if WOLFSSL_NO_DER_TO_PEM.
Implement RFC8773bis (draft-ietf-tls-8773bis-13)
cert_with_extern_psk for TLS 1.3, including protocol checks
and API support.
Includes unit tests for API and handshake behavior as well
as tests in the testsuite using extended examples.
* implement legacy compatibility in settings.h and configure.ac (adds --enable-blake2b while retaining --enable-blake2);
* fix incorrect Blake2 gates in wolfcrypt/src/hash.c wc_HashGetDigestSize() and wc_HashGetBlockSize();
* in wolfcrypt/test/test.c hash_test(), backfill missing Blake2 test coverage and separate blake2b from blake2s in typesHashBad[];
* in tests/api/test_hash.c, separate blake2b from blake2s in notCompiledHash[], sizeSupportedHash[], and sizeNotCompiledHash[].
Add settings.h include before the compile guard in asn_orig.c so
WOLFSSL_IGNORE_FILE_WARN is available when compiled separately.
Add -Wno-pedantic for asn_orig.c in async examples Makefile to
suppress empty translation unit warning.
wolfssl/ssl.h, examples/client/client.c, examples/server/server.c, src/bio.c, tests/api.c: add error tracing for WOLFSSL_SHUTDOWN_NOT_DONE.
tests/api.c: in test_wolfSSL_read_write_ex(), use WOLFSSL_SUCCESS rather than 1 for expected-success wolfSSL_shutdown()s, and add note that the wrong value is being returned (the test currently always fails, which is masked by an always-success retval).
* Enable ML-KEM by default in build systems (autoconf and CMake)
* Only allow three to-be-standardized hybrid PQ/T combinations by
default
* Use X25519MLKEM768 as the default KeyShare in the ClientHello (if user
does not override that). When Curve25519 is disabled, then either
WOLFSSL_SECP384R1MLKEM1024 or WOLFSSL_SECP256R1MLKEM768 is used as
default depending on the ECC configuration
* Disable standalone ML-KEM in supported groups by default (enable with
--enable-tls-mlkem-standalone)
* Disable extra OQS-based hybrid PQ/T curves by default and gate
behind --enable-experimental (enable with --enable-extra-pqc-hybrids)
* Reorder the SupportedGroups extension to reflect the preferences
* Reorder the preferredGroup array to also reflect the same preferences
* Add async support for ML-KEM hybrids
* DTLS 1.3 cookie and CH frag handling
* static memory handling
* Fix memory leak in TLS server PQC handling in case of ECH
* Make sure hybrids are actually tested in testsuite
