- 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.
