* QUIC DEMUX: Allow MTU to vary over time and autodetect MTUHugo Landau2023-01-131-1/+0

* QUIC: Remove RX depacketiser tests from QRL test suiteHugo Landau2023-01-131-142/+45
| | | | | | | | | | | These create significant coupling between the QRL tests and the RXDP. Moreover, the RXDP has no state of its own and is implemented as part of the QUIC_CHANNEL, ergo it doesn't make that much sense to test it in isolation.

* QUIC RX: Refactor unsafe DCID consistency checkingHugo Landau2023-01-131-13/+12
| | | | | | | | | | | | | | Previously, we enforced the requirement that the DCIDs be the same for all packets in a datagram by keeping a pointer to the first RXE generated from a datagram. This is unsafe and could lead to a UAF if the first packet is malformed, meaning that no RXE ended up being generated from it. Keep track of the DCID directly instead, as we should enforce this correctly even if the first packet in a datagram is malformed (but has an intelligible header with a DCID and length).

* QUIC Wire Encoding: Support Retry Integrity Tag CalculationHugo Landau2023-01-131-3/+41
| | | | | | | | | | | This adds support for calculating and verifying retry integrity tags. In order to support this, an 'unused' field is added to the QUIC packet header structure so we can ensure that the serialization of the header is bit-for-bit identical to what was decoded.

* QUIC RX: Do not handle auto-discard of Initial EL inside the QRXHugo Landau2023-01-131-15/+10
| | | | | | | | | | | While the QUIC RFCs state that the Initial EL should be auto-discarded when successfully processing a packet at a higher EL, doing this inside the QRX was not a good idea as this should be handled by the CSM. We remove this functionality and adapt tests accordingly.

* QUIC RX: Support refcounted packets and eliminate wrapperHugo Landau2023-01-131-8/+8
| | | | | | | | | | | | | | Previously, the QRX filled in a OSSL_QRX_PKT structure provided by the caller. This necessitated the caller managing reference counting itself using a OSSL_QRX_PKT_WRAP structure. The need for this structure has been eliminated by adding refcounting support to the QRX itself. The QRX now outputs a pointer to an OSSL_QRX_PKT instead of filling in a structure provided by the caller. The OSSL_QRX_PKT_WRAP structure has been eliminated.

* TX key update support, RX time and PN reporting, general refactoringHugo Landau2022-09-021-4/+592
| | | | | | | | | | | | | | | | | | - Adds an RX time field to the OSSL_QRX_PKT structure. - Adds a timekeeping argument to ossl_demux_new which is used to determine packet reception time. - Adds a decoded PN field to the OSSL_QRX_PKT structure. This has to be decoded by the QRX anyway, and its omission was an oversight. - Key update support for the TX side. - Minor refactoring.
