The TLS 1.2 server derived the single advertised ClientCertificateType
and the signature_algorithms list in its CertificateRequest from the
negotiated cipher suite's own signature algorithm. On an ECDHE-ECDSA
suite only ecdsa_sign was offered (and only ECDSA sig algs), so RSA
clients could not authenticate even though the server could happily
verify an RSA certificate. The same was true in reverse for an RSA
server: the CertificateRequest only advertised rsa_sign.
Refactor SendCertificateRequest to advertise certificate_types and
signature_algorithms covering both sig families when both are compiled
in. Three static helpers in internal.c keep the logic in one place
without mutating ssl->suites:
GetServerCertReqCertTypes - certificate_types to emit
GetServerCertReqHashSigAlgo - signature_algorithms to emit
InServerCertReqHashSigAlgo - membership check used for verification
The advertised lists are written to stack buffers in the caller. To
keep DoCertificateVerify in agreement with what we actually sent, the
SupportedHashSigAlgo call site there is replaced with
InServerCertReqHashSigAlgo, which rebuilds the same list locally and
looks up the client's chosen algo.
Replace the magic certTypes buffer size with a new
MAX_CERT_REQ_CERT_TYPE_CNT constant declared next to
ClientCertificateType.
Add two end-to-end mutual-auth tests covering both directions:
test_tls12_ecdhe_ecdsa_rsa_client_cert - ECDSA server, RSA client
test_tls12_ecdhe_rsa_ecdsa_client_cert - RSA server, ECDSA client
Update test_certreq_sighash_algos to permit RSA / RSA-PSS sig algs in
the ECDHE-ECDSA CertificateRequest; the previous assertion locked in
the ECDSA-only behaviour that this change corrects.
TLS 1.3 is unaffected: RFC 8446 removed certificate_types from
CertificateRequest, and TLS 1.3 cipher suites do not bind a signature
algorithm, so the server's hashSigAlgo already covers both sig
families when either has been compiled in.
Forks with Actions enabled would otherwise run the membrowse build matrix on push/workflow_dispatch and report fork builds to the membrowse backend. Guard the jobs in both workflows with github.repository_owner == 'wolfssl' (combined with the existing draft check in the report workflow), matching tls-anvil.yml and coverity-scan-fixes.yml.
Also default the analyze/onboard matrix to '[]' so strategy expansion does not error when load-targets is skipped on forks or draft PRs.
* Fixes frivolous ASSERT_SAVED_VECTOR_REGISTERS() in sp_#_div_#(),
* Adds "force off unneeded vector register save/restore." macro masking to all archs, and
* Removes now-unused x86 SSE2 asm implementations of sp_#_get_from_table_#().
Fixed left shifts to be on unsigned types.
Mod exp change to correctly get the highest indeces of exponent -
corrected in some places and now the same in all.
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().
wolfcrypt/src/sp_x86_64.c:
* fix ASSERT_SAVED_VECTOR_REGISTERS() in C wrappers: add where missing for implementations that use AVX2, and remove frivolous checks for ones that don't.
* refactor vector save-restore with a single locally tracked save in sp_RsaPublic_#(), sp_RsaPrivate_#(), sp_ecc_mulmod_add_#(), sp_ecc_mulmod_base_add_#(), sp_ecc_make_key_#(), and sp_#_calc_s_#().
* fix feature test in sp_ModExp_Fp_star_1024(), sp_Pairing_1024(), and sp_Pairing_gen_precomp_1024(), to properly gate on IS_INTEL_AVX2(cpuid_flags) and SAVE_VECTOR_REGISTERS2() == 0.
wolfcrypt/src/{dh.c,dsa.c,ecc.c,eccsi.c,rsa.c,sp_int.c}:
* remove all vector register provisions (SAVE_VECTOR_REGISTERS(), RESTORE_VECTOR_REGISTERS(), ASSERT_SAVED_VECTOR_REGISTERS());
* add explicit WC_CHECK_FOR_INTR_SIGNALS() and WC_RELAX_LONG_LOOP() to the lengthy loops in wc_DhGenerateParams(), wc_MakeDsaParameters(), ecc_sign_hash_sw(), and wc_MakeRsaKey().
wolfssl/wolfcrypt/{error-crypt.h,logging.h,memory.h}:
* make wc_backtrace_render() and wc_backtrace_set_fp() available whenever defined(WOLFSSL_DEBUG_BACKTRACE_ERROR_CODES);
* add support for DEBUG_VECTOR_REGISTERS_BACKTRACE_ON_FAIL, activating backtraces on vector register errors.
* also improve the debugging format from the DEBUG_VECTOR_REGISTER_ACCESS variants of SAVE_VECTOR_REGISTERS() and friends.
linuxkm/lkcapi_{dh,ecdh,ecdsa,rsa}_glue.c: harmonize PK driver names with AES, SHA, and DRBG, notably adding AVX2 annotation when enabled.
wolfcrypt/src/{sp_x86_64_asm.S,sp_x86_64_asm.asm}: synchronize with wolfssl/scripts#581 (removes SSE2 implementations of sp_#_get_from_table_#(), which no longer have users).
Move out DTLS 1.3 specific tests into test_dtls13.c. (Also move out from
test_dtls.c)
Move out DTLS tests into test_dtls.c.
Move out LMS and XMSS tests into test_lms_xmss.c.
Move out SSL session tests into test_session.c.
Move out remaining ML-DSA/Dilithium tests in api.c into test_mldsa.c.
Remove outdated RFC, refactor into single error case, guard against negative/0 len and NULL *data pointer, don't set ownStatus until status is confirmed non-NULL.
Enable all-zero shared secret check for Curve448/25519 by default. Ensure post_handshake_auth extension was sent before accepting post-handshake CertificateRequest message.
wolfssl/wolfcrypt/wc_mldsa.h: move WOLFSSL_MLDSA_NO_CTX setup to precede legacy dilithium.h header, so that the _NO_CTX remap macros are properly gated in.
