  "message": "snap: fix race condition\n\nWith the SNAP out-of-band SCTP connect (WebRTC-Sctp-Snap), the dcSCTP\nsocket is created in DcSctpTransport::Start() but only connected later\nin MaybeConnectSocket(), once the DTLS transport becomes writable. The\nDTLS transport can decrypt and deliver an inbound packet as soon as its\nhandshake completes, which precedes writability (set_writable() is\ndeferred until ICE is writable). A packet arriving in that window is\ndelivered to the still-kClosed socket, which rejects it as having an\ninvalid verification tag.\n\nEnd-to-end this is masked by SCTP retransmission, so it only surfaces as\nan \u0027invalid verification tag\u0027 log line and a one-RTO delay opening the\ndata channel. The dcsctp_transport unit test observes the drop directly\nvia the mock socket.\n\nBug: webrtc:526609852\nChange-Id: Iff17f2deb766ae465d68728d613e8c17d046263e\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/484720\nReviewed-by: Victor Boivie \u003cboivie@webrtc.org\u003e\nReviewed-by: Denise Tell \u003cdct@google.com\u003e\nCommit-Queue: Philipp Hancke \u003cphilipp.hancke@googlemail.com\u003e\nCr-Commit-Position: refs/heads/main@{#48061}\n",
