Appending in this case can\nhit skb_put overflow conditions.\n\nReject aggregation when the target skb tailroom cannot accommodate the new\npacket. The caller then falls back to creating a new forward packet\ninstead of appending."}], "lastModified": "2026-04-25T09:16:02.037", "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
