- Retry wolfSSL_write on the same recoverable send errors the plain-UDP
baseline already retries on: EAGAIN/EWOULDBLOCK surface as WANT_WRITE
and ENOBUFS as SOCKET_ERROR_E with errno preserved. The buffered
record is flushed by the retried call without re-encrypting.
- Treat an explicit -? as a help request: print usage to stdout and
exit 0, keeping stderr and a failure exit for genuine option errors.
- Enumerate ciphers with wolfSSL_get_cipher_list() instead of an 8 KiB
stack buffer, and range-check -p and -b like the other numeric
options.
- Document in BuildMessage that the FIPS<2 path overwrites the
explicit-nonce placeholder inside BuildMessage itself, and that the
one path transmitting the bytes as written (ATOMIC_USER MacEncryptCb)
still emits the sequence number that RFC 5288 et al. prescribe.
Fail loudly if clock_gettime() ever fails instead of computing
throughput from uninitialized stack, and warn when -z is combined with
-s since the sink-send only applies to the client.
dtls_bench.c is built whenever DTLS and the example servers are enabled,
including the cross-mingw-all-crypto multi-test scenario, which cross-
compiles for Windows. It directly includes POSIX-only headers
(<sys/socket.h>, <arpa/inet.h>, <netdb.h>, <net/if.h>) that mingw does
not ship, so the build failed there.
Gate the networking includes and the whole benchmark body behind a
DTLS_BENCH_ENABLED check (WOLFSSL_DTLS, not USE_WINDOWS_API, not
WOLFSSL_NO_SOCK). When the platform lacks POSIX BSD sockets, compile a
small stub main() that reports the tool is unsupported, so the source
tree still builds.
Add examples/benchmark/dtls_bench, a DTLS throughput benchmark that
completes a handshake and then measures bulk-send throughput. It
supports DTLS 1.2 and 1.3, selectable cipher suites, an end-to-end
mode, and a -z sink mode that discards records on the server after the
handshake to isolate the sender's record-layer cost. The socket is set
up with wolfSSL_set_dtls_fd_connected.
Optimize the send path exercised by the benchmark:
- wolfio (EmbedSendTo): cache the per-descriptor socket-type probe
(getsockopt SO_TYPE) in WOLFSSL_DTLS_CTX instead of running it on
every send, removing a syscall from the record send path. The cache
is invalidated whenever rfd/wfd is reassigned.
- internal (BuildMessage): for AEAD suites whose explicit nonce is the
8-byte record sequence number, write the sequence number directly as
nonce_explicit instead of drawing it from the RNG. This covers
AES-GCM (RFC 5288 sec 3), AES-CCM (RFC 6655 sec 3), SM4-GCM/CCM
(RFC 8998 sec 3), and Camellia-/ARIA-GCM which inherit the RFC 5288
construction; ChaCha20 uses an implicit nonce and is excluded. A new
read-only PeekSEQ() helper reads the sequence number without advancing
the per-direction counter, leaving the single mandated increment to
writeAeadAuthData().
Also ignore the built dtls_bench binary in .gitignore.
* 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
When both TLS 1.3 and Brainpool curves are enabled, three new groups can
be used for the ECDHE key exchange according to RFC 8734:
* WOLFSSL_ECC_BRAINPOOLP256R1TLS13 (31)
* WOLFSSL_ECC_BRAINPOOLP384R1TLS13 (32)
* WOLFSSL_ECC_BRAINPOOLP512R1TLS13 (33)
Also ensure that the existing TLS 1.2 curves are sent properly.
The TLS client application is updated to support handshakes via
Brainpool curves using the new argument "--bpKs".
Add support for X25519 and X448 based hybrid PQC + ECC key exchange
groups. Furthermore, two new combinations with SECP curves are added to
match OQS combinations.
This also incorporates the changed order of X25519 and X448 based
combinations to place the PQC material before the ECDH material. This is
motivated by the necessity to always have material of a FIPS approved
algorithm first.
Also, codepoints are updated to reflect the latest draft standards for
pure ML-KEM and some of the hybrids. With these changes and based on the
recent additions to both enable ML-KEM final and draft versions
simultaneously, a WolfSSL TLS server is now compatible with all recent
browsers that support either the draft version of ML-KEM (Chromium based
browsers and Firefox < version 132; only when the draft version is
enabled in the build) or the final version already (Firefox > version 132).
In the process of extending support, some code and logic cleanup
happened. Furthermore, some memory leaks within the hybrid code path have
been fixed.

* Correct cmake script to support Open Watcom toolchain (#8167)
* Fix thread start callback prototype for Open Watcom toolchain (#8175)
* Added GitHub CI action for Windows/Linux/OS2
* Improvements for C89 compliance.
Thank you @jmalak for your contributions.
Make Kyber and ML-KEM individually available as well as at the same
time.
Modified TLS layer to support both Kyber and ML-KEM.
Added new identifiers in TLS layer for ML-KEM.
configure.ac:
* add --enable-all-osp to separate OSP meta-feature sets from --enable-all, allowing --enable-all --disable-all-osp --disable-opensslall (e.g. for testing OPENSSL_COEXIST).
* fix enable_all_crypto=yes in enable-all to be conditional on "$enable_all_crypto" = "".
* move enable_rsapss=yes from enable-all to enable-all-crypto.
examples/ and testsuite/: #undef OPENSSL_COEXIST unconditionally rather than only if defined(OPENSSL_EXTRA), to capture -DOPENSSL_EXTRA_X509_SMALL or any other such variants.
No functional changes.
Several compat symbols that were formerly enums are now macros.
All library source is refactored to use only native symbols in all code gated in with --enable-all-crypto --enable-opensslextra.
wolfcrypt/test/test.c is similarly refactored to use only native symbols.
examples/ and tests/ are unmodified except for header setup to disable OPENSSL_COEXIST and TEST_OPENSSL_COEXIST.
tests/api.c: add error_test() adapted from wolfcrypt/test/test.c, checking all error strings for expected presence/absence and length, called from existing test_wolfSSL_ERR_strings().
wolfssl/ssl.h, wolfssl/error-ssl.h, and wolfssl/wolfcrypt/error-crypt.h:
* move several negative error return codes from ssl.h to error-ssl.h,
* renumber them to conform to existing sequence, and
* include error-ssl.h from ssl.h;
* add special-case WOLFSSL_DEBUG_TRACE_ERROR_CODES macros for WOLFSSL_FAILURE;
* add missing WOLFSSL_API attribute to wc_backtrace_render().
add numerous WC_NO_ERR_TRACE()s to operand error code uses, cleaning up error traces in general, and particularly when WOLFSSL_DEBUG_TRACE_ERROR_CODES_ALWAYS.
* crypto lib (36),
* crypto test&benchmark (20),
* TLS lib (179),
* examples (122),
* linuxkm (3),
* tests/api.c (2272).
Fix checking of negative with unsigned variables.
Check digestSz for 0 in wc_SSH_KDF() so that no possibility of dividing
by zero.
Change XMEMCPY to XMEMSET in renesas_sce_util.c.
Fix test.c to free prvTmp and pubTmp on read error.
Remove unused variables.
XFREE checks for NULL so don't check before call.
Move variable declarations to reduce scope.
