Pull request overview
This PR tightens TLS compliance-related behavior in the core handshake and exporter paths, primarily by enforcing correct timing/validity constraints for keying material export and session ticket usage.
Changes:
- Refuse
wolfSSL_export_keying_material()calls until the handshake has fully completed (per RFC 8446 / RFC 5705 intent). - Suppress use of expired stored session tickets (fall back to full handshake instead of attempting resumption).
- Map
BUFFER_Etodecode_errorinTranslateErrorToAlert().
