Detailed Description

Per-connection UDIF state layered atop a QSTP channel.

The qstpcns field is held by reference; its lifetime is managed through the QSTP API. The tunnel record pairs it with UDIF-specific policy state for the duration of the session.

Field Documentation

◆ closing

bool closing

Set true once a close has been initiated

◆ epoch

uint64_t epoch

Current UDIF tunnel epoch

◆ idledeadline

uint64_t idledeadline

UTC seconds past which session is torn down

◆ keepalivedeadline

uint64_t keepalivedeadline

UTC seconds at which next keepalive should be sent

◆ lastrxsecs

uint64_t lastrxsecs

UTC seconds of last successful receive

◆ lasttxsecs

uint64_t lasttxsecs

UTC seconds of last successful send

◆ peerserial

uint8_t peerserial[UDIF_SERIAL_NUMBER_SIZE]

Remote entity certificate serial

◆ qstpcns

qstp_connection_state* qstpcns
