A failure that ends the run: the guest asked for something the recording cannot answer, or that this version does not model.

Variants

WrongMode

The operation needs a different mode (for example a replay-only call during record).

UnknownChannel(OpenFileId)

ChannelExists(OpenFileId)

A channel connected twice.

NotInTrace(OpenFileId)

Replay connected a socket the recording never connected.

PeerMismatch

Fields

channel: OpenFileId

recorded: NetworkAddressV1

attempted: NetworkAddressV1

OutboundMismatch

Replay transmitted bytes that differ from the recording.

Fields

channel: OpenFileId

offset: u64

OutboundBeyondRecording

Replay transmitted more bytes than the recording holds.

Fields

channel: OpenFileId

offset: u64

BlockingSendAtRefusal

Replay made a blocking send where the recording holds a nonblocking send that Linux refused with EAGAIN.

Fields

channel: OpenFileId

offset: u64

NonblockingSendAtWait

Replay made a nonblocking send where the recording holds a fragment that a blocking send waited for buffer space to send.

Fields

channel: OpenFileId

offset: u64

InterleavedSend

Record: another send, accepted or refused, reached the stream while a blocking send waited for buffer space, so the stream interleaves the two.

Fields

channel: OpenFileId

offset: u64

InvalidArrival(OpenFileId)

The recorder fed an arrival after the stream ended, or an empty one.

Trace(NetworkTraceValidationError)

The finished recording failed validation.

UntraceablePeer(NetworkAddressV1)

Record connected to a peer a trace cannot hold.

ReplayStalled

Replay waited REPLAY_STALL_LIMIT past the recorded arrival of an input that the recording released only after the guest had sent needed bytes; this replay has sent sent.

Fields

channel: OpenFileId

needed: u64

sent: u64

ReplayUnconnected(OpenFileId)

Replay ended without connecting a socket the recording connected.

ReplayUnsent

Replay ended having sent sent of the recorded bytes on a channel.

Fields

channel: OpenFileId

sent: u64

recorded: u64

ReplayUnrefused

Replay ended without the nonblocking send that the recording holds, refused with EAGAIN, at stream offset offset.

Fields

channel: OpenFileId

offset: u64
