  "message": "Revert Backoff [v3]: Revert RTO on ICMP destination unreachable\n\nHere, an ICMP host/network unreachable message, whose payload fits to\nTCP\u0027s SND.UNA, is taken as an indication that the RTO retransmission has\nnot been lost due to congestion, but because of a route failure\nsomewhere along the path.\nWith true congestion, a router won\u0027t trigger such a message and the\npatched TCP will operate as standard TCP.\n\nThis patch reverts one RTO backoff, if an ICMP host/network unreachable\nmessage, whose payload fits to TCP\u0027s SND.UNA, arrives.\nBased on the new RTO, the retransmission timer is reset to reflect the\nremaining time, or - if the revert clocked out the timer - a retransmission\nis sent out immediately.\nBackoffs are only reverted, if TCP is in RTO loss recovery, i.e. if\nthere have been retransmissions and reversible backoffs, already.\n\nChanges from v2:\n1) Renaming of skb in tcp_v4_err() moved to another patch.\n2) Reintroduced tcp_bound_rto() and __tcp_set_rto().\n3) Fixed code comments.\n\nSigned-off-by: Damian Lukowski \u003cdamian@tvk.rwth-aachen.de\u003e\nAcked-by: Ilpo Järvinen \u003cilpo.jarvinen@helsinki.fi\u003e\nSigned-off-by: David S.
