Change GetLength() return check from > 0 to >= 0 in wolfSSL_ASN1_INTEGER_get_length
and wolfSSL_ASN1_INTEGER_get0_data. GetLength returns the decoded length (≥ 0) on
success and negative error codes on failure, so checking > 0 incorrectly excluded
zero-length values, making the DER-stripping logic dead code.
In OpenSSL, ASN1_INTEGER is typedef'd to ASN1_STRING (same struct), so
calling ASN1_STRING_length() / ASN1_STRING_get0_data() on an
ASN1_INTEGER* is valid and well-defined. wolfSSL has them as distinct,
incompatible structs. This fixes the openvpn master failures introduced in
https://github.com/OpenVPN/openvpn/pull/1003
- wolfSSL_X509_verify_cert: add host check from `ctx->param`
- wolfSSL_X509_verify_cert: Set `ctx->error_depth` on error
- Use WOLFSSL_-prefixed error constants (always available) instead of
OPENSSL_COEXIST-guarded macros, fixing error code mismatch in
coexist builds
- Set ctx->current_cert = orig on hostname/IP mismatch so error
reporting aligns with error_depth = 0 (leaf cert)
- Add IP address verification test cases (match + mismatch)
- Copy TLS 1.3 traffic secrets and DTLS 1.3 epoch/cipher state to the
write-dup side in DupSSL so key updates can be performed.
- Delegate KeyUpdate responses from the read side to the write side via
the shared WriteDup struct, for both peer-initiated and local key
updates.
- Delegate DTLS 1.3 ACK sending from the read side to the write side.
- Track DTLS 1.3 KeyUpdate ACKs: write side records the in-flight
KeyUpdate epoch/seq, read side sets keyUpdateAcked when the matching
ACK arrives.
- Delegate post-handshake certificate authentication (CertificateRequest
processing) from the read side to the write side, transferring
transcript hashes, cert context, and signature parameters.
- Reset prevSent/plainSz to prevent stale values from SendData to think
that data was already sent.
- Refactor FreeHandshakeHashes into Free_HS_Hashes for reuse.
- Move DTLS 1.3 epoch initialization earlier in InitSSL so the
write-dup early-return path has valid epoch state.
- Add tests for write dup with all protocol versions, key update,
post-handshake auth, and WANT_WRITE recovery.
- Add --enable-all --enable-writedup to CI os-check matrix.
wolfssl/ssl.h, examples/client/client.c, examples/server/server.c, src/bio.c, tests/api.c: add error tracing for WOLFSSL_SHUTDOWN_NOT_DONE.
tests/api.c: in test_wolfSSL_read_write_ex(), use WOLFSSL_SUCCESS rather than 1 for expected-success wolfSSL_shutdown()s, and add note that the wrong value is being returned (the test currently always fails, which is masked by an always-success retval).
