This makes\nthe full-pass termination independent of the transport state while\npreserving the existing fallback selection semantics.\n\nAlso restore the NULL guard around the retran_path assignment. In the\nall-UNCONFIRMED case there is no eligible replacement transport, and\ninstalling NULL would leave later retransmit-path users and the debug\nprint with a NULL path.","state":0,"publishedAt":"2026-10-18T15:19:34.494+00:00","modifiedAt":"2026-10-19T09:22:42.185+00:00","affected":[{"ecosystem":"Vendor
