Leak fixes: free existing ssl->buffers.key before overwriting in SetSSL_CTX() (internal.c) and wolfSSL_set_SSL_CTX() (ssl.c)
UAF fix: wc_CheckRsaKey() — mp_memzero_check(tmp) moved before the free (rsa.c)
Build guards: #ifndef NO_ED25519/ED448_VERIFY around forged-sig test data (test_ed25519/ed448.c); guard equal()/cmov() for verify-only builds (ge_operations.c); guard unused pointers under WOLFSSL_MLDSA_SIGN_SMALL_MEM_PRECALC (wc_mldsa.c)
Test cleanups (test.c): fix UB from out-of-range enum in hash_test(), always free AES dec object, fix der buffer declaration under small-stack builds
After the SHA-512/224 and /256 fallback to the generic SHA-512 callback,
restore the variant initial state so the object is reset for reuse, and
exercise the path in cryptocb_test.
1. Side-aware ML-KEM in TLS (tls.c, tls13.c, ssl.c, internal.h):
TLSX_IsGroupSupported/TLSX_UseSupportedCurve take a `side` arg; new
TLSX_IsMlKemGroupSupported + client/server support macros. A build only
capable of one ML-KEM op no longer advertises groups it can't use for
its role.
2. NO_ASN_TIME support (ssl_asn1.c, ssl.h, settings.h): data-only
ASN1_TIME APIs now compile without system time; OCSP responder
auto-disabled under NO_ASN_TIME.
3. SP ECC (sp_*.c, sp_x86_64_asm.asm): curve `b` constants and
sp_ecc_is_point_* always compiled (point-check available in more
configs); asm movsxd -> movsx.
4. configure.ac: BUILD_MEMUSE fixed to trigger on != "xno".
5. Test fixes: HRR-aware TLS 1.3 memio tests (new
test_memio_msg_is_hello_retry_request); tightened build guards
(Ed25519/Ed448 key-import, AES decrypt, XMSS heights, SP sizes,
static-PSK).
wolfssl/wolfcrypt/settings.h: add WC_NO_GLOBAL_OBJECT_POINTERS implicitly in WC_SYM_RELOC_TABLES section of WOLFSSL_LINUXKM setup.
wolfssl/wolfcrypt/wolfmath.h, wolfcrypt/src/wolfmath.c, wolfcrypt/src/sp_int.c, wolfcrypt/src/sakke.c: when WC_NO_GLOBAL_OBJECT_POINTERS, use static local wc_off_on_addr rather than global in wolfmath.c.
wolfcrypt/src/sakke.c:
* in wc_DeriveSakkeSSV(), initialize a[] with explicit XMEMSET() rather than " = {0}", to avoid unmaskable implicit memset() emitted by compiler.
* remove all vector register provisions (SAVE_VECTOR_REGISTERS(), RESTORE_VECTOR_REGISTERS(), ASSERT_SAVED_VECTOR_REGISTERS()).
linuxkm/module_exports.c.template: add includes for eccsi.h and sakke.h.
configure.ac:
* tweak enable-all-crypto setup to make enable_eccsi unconditional alongside enable_fpecc;
* move enable_sakke to be conditional only on !FIPS.
* notably this activates ECCSI and SAKKE on kernel all-crypto builds.
wolfcrypt/test/test.c: WC_*_VAR*() refactors for eccsi_test() and sakke_test().
Add defense-in-depth checks to wc_ed{25519,448}_check_key() and
ed{25519,448}_verify_msg_final_with_sha() that reject the identity
point and other small-order public keys. Honest EdDSA key generation
never produces such keys, but wolfSSL previously accepted them on
import and verification. The guard runs at both entry points so it
holds even when a key is imported with trusted=1. New tests are gated
on !HAVE_FIPS || FIPS_VERSION3_GE(7,0,0).
sp_set_bit(): check i is in range before use.
_sp_div_2(): Use a constant-time clamp as called by a constant-time
function.
_sp_sqr(): static buffer needs to be one larger for when ECC with P-521
is the largest size.
Add tests:
- Testing negative numbers with mp_read_raidx/mp_to_radix 10/16
- Testing negative numbers with mp_add_d/mp_sub_d
- Testing of mp_gcd without mp_lcm
- More testing of mp_mod_d and when negative numbers are used
- Check maximum values work for square. Check of _sp_sqr() bug
- Add testing of mp_add/sub_mod_ct
- Add testing of mp_cmp_mag
- Add testing of mp_mulmod/mp_sqrmod
- Add testing of mp_exch
- Add testing of mp_to_unsigned_bin_len_ct
- Add testing of mp_exptmod that uses base-2 windowing method.
- Add testing of mp_invmod_mont_ct
Modes (CTR, GCM, CCM, etc.) can be supported either directly or fallback
to invoking the crypto callback with a "direct" (ECB) mode.
Software implementation and AES tables are stripped under CB_ONLY_AES.
wc_swdev gains AES support so WOLF_CRYPTO_CB_ONLY_AES builds can be
tested.
crypto find cb support added to wc_AesSetKey in order to support current
CI tests that use INVALID_DEVID.
Add WOLF_CRYPTO_CB_ONLY_SHA256: when set, the SHA-256 software.
wc_Sha256FinalRaw is reduced to a stub returning NO_VALID_DEVID, and
sha256.h force-defines WOLFSSL_NO_HASH_RAW so the constant-time TLS HMAC
path falls back to its backend-opaque variant.
Incompatible with
WOLFSSL_SHA224, which aliases the SHA-256 statics; #error guard added.
Add wc_swdev support for SHA-256 for testing.
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.
Top-level test extraction into typed sub-functions
- Digest tests (MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512,
SHA-512/224, SHA-512/256, SHA-3 224/256/384/512, SHAKE128/256): each
test category (KAT, large-hash, copy-cleanup, unaligned-memory,
interleave, copy-Sha3 heap-allocation pattern) is now its own static
wc_test_ret_t function rather than inline blocks inside one giant
top-level test.
- rsa_test: extracted rsa_pkcs1_test, rsa_cert_parse_test,
rsa_pub_key_decode_test, rsa_certreq_test.
- ecc_test: extracted ecc_test_all_curves, ecc_test_all_deterministic_k
from the dispatcher; ecc_encrypt_combos_test from ecc_encrypt_test;
ecc_buffers_encrypt_test, ecc_buffers_sign_verify_test,
ecc_buffers_pub_key_decode_test from ecc_test_buffers.
- dh_test: extracted dh_keyagree_test, dh_check_priv_key_test,
dh_agree_ct_test, dh_key_import_export_test, dh_set_check_key_test.
- Curve25519 / Ed25519 / Curve448 / Ed448: extracted KAT, key-agreement,
ASN, and rare-sig sub-tests from each top-level dispatcher.
- Cipher tests: extracted streaming sub-tests from aesofb_test,
aescfb_test, aes_cts_test (aes_cts_192/256_stream_test).
Coverage additions
- Added state-copy testing inside the SHA-3 KAT loops (matching the
existing pattern in SHA-1/224/256/etc. KAT loops).
- Added a SHA-224 large-hash test (parity with the other digest
families).
- Added copy-cleanup tests for SHA-512/224 and SHA-512/256.
- Added Unaligned memory access testing to all *_large_hash_test
functions (MD5, SHA-1/224/256/384, SHA3-224/256/384/512), matching the
pattern that previously only existed for SHA-512/224/256.
