When building with --enable-opensslextra=x509small, only OPENSSL_EXTRA_X509_SMALL is defined, not OPENSSL_EXTRA, so these functions are not compiled into the library
NIST standardized the pre-standardization Dilithium signature scheme as
ML-DSA in FIPS 204. Migrate the provider's user-visible surface to
canonical spellings, with a temporary shim that preserves source-level
backward compatibility for existing consumers.
Renames
-------
* File: wolfcrypt/src/dilithium.c -> wolfcrypt/src/wc_mldsa.c
* New canonical header: wolfssl/wolfcrypt/wc_mldsa.h
* Types: dilithium_key -> MlDsaKey, wc_dilithium_params -> MlDsaParams
* Functions: wc_dilithium_* / wc_Dilithium_* -> wc_MlDsaKey_*
* Build gates: HAVE_DILITHIUM -> WOLFSSL_HAVE_MLDSA,
WOLFSSL_DILITHIUM_* / WC_DILITHIUM_* -> WOLFSSL_MLDSA_* / WC_MLDSA_*
* Configure flag: --enable-mldsa (legacy --enable-dilithium still works)
* CMake option: WOLFSSL_MLDSA (legacy WOLFSSL_DILITHIUM emits a
DEPRECATION message)
Backward compatibility
----------------------
wolfssl/wolfcrypt/dilithium.h is now a temporary compatibility shim:
* Forward-translates legacy build gates to canonical (the two sub-gates
read by certs_test.h are translated in settings.h so the auto-generated
header is reachable without including dilithium.h; the remainder lives
in dilithium.h itself).
* Reverse-translates canonical gates back to legacy so unmigrated
consumer code keying off HAVE_DILITHIUM / WOLFSSL_DILITHIUM_* keeps
compiling.
* Provides macro / static-inline aliases for the legacy type and
function names so source-level callers compile unchanged. Sets
WC_DILITHIUMKEY_TYPE_DEFINED to suppress strict-C99 typedef
redefinition in asn_public.h.
Two opt-outs are honored: WOLFSSL_NO_DILITHIUM_LEGACY_GATES disables
build-gate translation; WOLFSSL_NO_DILITHIUM_LEGACY_NAMES disables the
symbol aliases. Both are temporary and the shim will be removed in a
future release. doc/dilithium-to-mldsa-migration.md describes the
migration path for downstream consumers.
ABI note
--------
The library now exports wc_MlDsaKey_* instead of wc_dilithium_*.
Pre-built binaries that linked against the legacy symbols need to
recompile against the shim header (which resolves to the new symbols at
compile time) or migrate to the canonical names directly. Source code
keeps building unchanged.
Other changes
-------------
* wolfssl/wolfcrypt/memory.h: drop ML-DSA sub-gate branching for static
memory pool sizing; WOLFSSL_HAVE_MLDSA builds now pick the larger
LARGEST_MEM_BUCKET / WOLFMEM_BUCKETS / WOLFMEM_DIST unconditionally.
Override these macros for small-mem builds.
* gencertbuf.pl + wolfssl/certs_test.h: outer guards migrated to the
canonical WOLFSSL_HAVE_MLDSA spelling.
* tests/api/test_mldsa.c: adds compile-time API surface validators
(canonical wc_MlDsaKey_* surface plus legacy alias surface) so
signature drift produces a build error during make check.
* IDE files (Xcode, INTIME-RTOS, WIN10, VS2022, CSharp wrapper), Zephyr
CMakeLists.txt, and autotools include.am updated for the rename.
* DYNAMIC_TYPE_DILITHIUM and ML_DSA_PCT_E retained as internal symbols;
scheduled to be renamed alongside the eventual shim removal.
DoTls13NewSessionTicket rejects a ticket lifetime greater than
MAX_LIFETIME (RFC 8446 Section 4.6.1, 7 days), but no test
exercised the rejection: every server in the suite stays well
within the limit, so a mutation deleting that bound check would
go unnoticed.
Add a manual memio test that pokes ctx_s->ticketHint to
MAX_LIFETIME + 1 (the public setter clamps to 604800), runs a
full TLS 1.3 handshake, and reads the post-handshake
NewSessionTicket on the client. The test confirms the over-limit
lifetime surfaces from wolfSSL_read as SERVER_HINT_ERROR.
F-2121
When resuming a session wolfSSL_SetSession unconditionally
overwrote ssl->version with the version stored in the cached
session, even if that version was below the WOLFSSL's configured
minDowngrade. The overwritten version then fed straight into
SendClientHello, so a client configured to require TLS 1.2 or
higher could still emit a ClientHello advertising e.g. TLS 1.0
when resuming an old cached session. The ServerHello path catches
the actual downgrade, but the ClientHello version is already a
protocol-conformance issue and can confuse middleboxes.
Reject the session if its stored minor version is below
ssl->options.minDowngrade. The check is DTLS-aware: DTLS minor
versions decrease as the protocol version increases, so the
direction of the comparison is flipped for DTLS.
F-2105
Extend the swdev callback to handle ECC operations: keygen, ECDH, sign,
verify, get-size, get-sig-size.
Relax WOLF_CRYPTO_CB_ONLY_ECC guards in the test suite so that tests run
under swdev, and wire wc_SwDev_Init/Cleanup into testsuite, client, and
server. Two tests are intentionally kept excluded even with swdev because
they call raw ECC math primitives (wc_ecc_mulmod, on-curve validation in
wc_ecc_import_x963) that are stripped below the cryptocb dispatch layer:
- ecc_mulmod_test (wolfcrypt/test/test.c)
- test_wc_ecc_import_x963_off_curve (tests/api/test_ecc.c)
Add a software crypto-callback device (wc_swdev) that lets the wolfcrypt
test suite run under WOLF_CRYPTO_CB_ONLY_* flags without per-test devId
plumbing. The bundle is a separately-compiled second copy of wolfcrypt
(software implementations enabled, WOLF_CRYPTO_CB_ONLY_* stripped) linked
into testwolfcrypt as a single relocatable object; every symbol is demoted
to local via objcopy --keep-global-symbol except wc_SwDev_Callback, so there
is no collision with the main libwolfssl.
A find callback routes unbound operations (devId == INVALID_DEVID) to the
swdev while letting real device IDs pass through.
wc_SwDev_Init / wc_SwDev_Cleanup hooks are wired into wolfcrypt/test/test.c.
cryptocb_test's WOLF_CRYPTO_CB_FIND and WOLF_CRYPTO_CB_ONLY_RSA blocks are
gated off under WOLFSSL_SWDEV.
Enable via --enable-swdev (requires --enable-cryptocb).
* in pbkdf2_test(), pwdbased_test(), and pkcs12_test(), add missing FIPS v7+
gates around stanzas that use wc_PBKDF_max_iterations_set() and
wc_PBKDF_max_iterations_get() or depend on erroring for excessive PBKDF
iterations (fixes#10050);
* in ecc_test_buffers(), omit new corrupt HMAC tag test on FIPS <v6 (fixes
8f2a3f9563).
tests/api/test_dtls.c: add FIPS v7+ gate to test_dtls13_frag_ch2_with_ch1_rtx().
wolfssl/wolfcrypt/memory.h: #include "../../linuxkm/linuxkm_memory.h" rather than "linuxkm/linuxkm_memory.h", following pattern in wc_port.h.
Adds resp_certid_keyhash_mismatch — a forged response signed by the
legitimate ocsp-responder whose CertID pairs the legitimate root CA's
issuerNameHash with the imposter root CA's issuerKeyHash. The new
test_ocsp_responder_keyhash_binding asserts wolfSSL_OCSP_basic_verify
rejects it, exercising the fix that requires both halves of the
CertID to match the responder's issuer.
