1947783 - DataChannel will assemble DATA chunks from different messages into the same message

Status: NEW

(Core :: WebRTC: Networking, defect, P3)

Description

[Byron Campen [:bwc]]

Right now we do not track separate messages when assembling DATA chunks. When we receive DATA chunks from multiple messages on the same DataChannel, all of them will be appended to the message we are currently assembling until we see an EOM chunk.

Uses bundle negotiation as a blunt instrument to cause packet loss, increasing
the probability that multiple messages are being assembled by the receiver
simultaneously.

Depends on D229272
