Extend wc_MakeCert_ex/wc_SignCert_ex/wc_MakeCertReq_ex to issue HSS/LMS and
XMSS/XMSS^MT certificates and PKCS#10 requests, building on the existing
RFC 9802 verification support. New LMS_TYPE/XMSS_TYPE/XMSSMT_TYPE selectors,
wc_{Lms,Xmss}Key_PublicKeyToDer SPKI encoders, runtime signature-buffer
sizing, and sigType/key consistency checks. Generation is ASN.1-template
only, matching where the verification path lives.
Tests generate self-signed roots, CSRs and a CA->ECC-leaf chain in-process
and verify them, replacing the patched Bouncy Castle fixtures (only the stock
RFC 9802-aligned LMS interop anchor is kept).
Extend test_tls13_apis with negative-count assertions for
wolfSSL_CTX_set_groups and wolfSSL_set_groups, and NULL-groups
assertions for wolfSSL_CTX_set1_groups and wolfSSL_set1_groups
(tests/api/test_tls13.c).
Add test_wolfSSL_get_shared_ciphers covering NULL ssl, NULL buf, and
zero-length inputs (tests/api/test_tls.c).
The two new tests (test_tls12_ecdhe_ecdsa_rsa_client_cert and
test_tls12_ecdhe_rsa_ecdsa_client_cert) were appended right after
test_wolfSSL_alert_desc_string, the last function in test_tls.c. Another
in-flight branch appends its own new tests at the same anchor, producing
a spurious add/add merge conflict even though the additions are
independent. Move these two functions just above
test_wolfSSL_alert_desc_string so the two branches insert at different
locations and merge cleanly. Pure code movement; no behavior change.
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.
Change to ignore plaintext alerts when
WOLFSSL_TLS13_IGNORE_PT_ALERT_ON_ENC is defined only until first
encrypted message from peer is seen.
Negative testing added.
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
Removed WOLFSSL_PSK_ID_PROTECTION from use as it is now on by default.
Always check whether the server has a certificate (not a CA chain).
If there is a certificate then continue, otherwise, report a binder
error.
Added test to ensure binder error returned and alert sent when no
NO_CERT. test_tls13_bad_psk_binder already tested no certificate.
Allowed memio test harness to be built when NO_CERT is defined.
- src/x509.c: Guard wolfSSL_X509_get_der against derCert->length > INT_MAX, and reject derSz <= 0 in wolfSSL_i2d_X509.
- tests/api/test_ossl_x509_io.{c,h}: Add API coverage for the X509 DER length guards.
