They may be stateless or may + relate only to global state. + + Can also be used for APIs implemented only in terms of other public libssl APIs. +- **Object**: + Object management APIs. Some of these may require QUIC-specific implementation. +- **HL**: Handshake layer API. + + These calls should generally be dispatched to the handshake layer, unless + they are not applicable to QUIC. Modifications inside the handshake layer + for the QUIC case may or may not be required. +- **CSSM**: Connection/Stream State Machine. API related to lifecycle of a + connection or stream. Needs QUIC-specific implementation. +- **ADP**: App Data Path. Application-side data path API. QUIC-specific + implementation. +- **NDP**: Net Data Path. Network-side data path control API. Also includes I/O + ticking and timeout handling. +- **RL**: Record layer related API. If these API items only relate to the TLS + record layer, they must be disabled for QUIC; if they are also relevant to the + QUIC record layer, they will require QUIC-specific implementation. +- **Async**: Relates to the async functionality. +- **0-RTT**: Relates to early data/0-RTT functionality. +- **Special**: Other calls which defy classification. + +The Semantics column is as follows: + +- **🟩U**: Unchanged. The semantics of the API are not changed for QUIC. +- **🟧C**: Changed. The semantics of the API are changed for QUIC. +- **🟦N**: New. The API is new for QUIC. +- **🟥TBD**: Yet to be determined if semantic changes will be required. + +The Applicability column is as follows: + +- **🟦U**: Unrelated. Not applicable to QUIC — fully unrelated (e.g. functions for + other SSL methods). +- **🟥FC**: Not applicable to QUIC (or not currently supported) — fail closed. +- **🟧NO**: Not applicable to QUIC (nor not currently supported) — no-op. +- **🟩A**: Applicable. + +The Implementation Requirements column is as follows: + +- **🟩NC**: No changes are expected to be needed (where marked **\***, dispatch + to handshake layer). + + **Note**: Where this value is used with an applicability of **FC** or **NO**, + this means that the desired behaviour is already an emergent consequence of the + existing code. +- **🟨C**: Modifications are expected to be needed (where marked **\***, + dispatch to handshake layer with changes inside the handshake layer). +- **🟧QSI**: QUIC specific implementation. +- **🟥QSA**: QUIC specific API. + +The Status column is as follows: + +- **🔴Pending Triage**: Have not determined the classification of this API item yet. +- **🟠Design TBD**: It has not yet been determined how this API item will work for + QUIC. +- **🟡TODO**: It has been determined how this API item should work for QUIC but it + has not yet been implemented. +- **🟢Done**: No further work is anticipated to be needed for this API item. + +Notes: + +- †1: Must restrict which ciphers can be used with QUIC; otherwise, no changes. +- †2: ALPN usage must be mandated; otherwise, no changes. +- †3: NPN usage should be forced off as it should never be used with QUIC; + otherwise, no changes. +- †4: Controls needing changes are listed separately. +- †5: TLS compression and renegotiation must not be used with QUIC, but these + features are already forbidden in + TLS 1.3, which is a requirement for QUIC, thus no changes should be needed. +- †6: Callback specified is called for handshake layer messages (TLSv1.3). +- †7: Tickets are issued using `NEW_TOKEN` frames in QUIC and this will + require handshake layer changes. However these APIs as such do not require + changes. +- †8: Use of post-handshake authentication is prohibited by QUIC. +- †9: QUIC always uses AES-128-GCM initially. We need to determine when and + what ciphers we report as being in use. +- †10: Not supporting async for now. + +| API Item | Cat. | Sema. | Appl. | Impl.
