Whether that\u0027s\n significant, I\u0027m not too sure.\n\nCurrently it will provide skipping by walking. Combined with\nRB-tree, all skipping would become fast too regardless of window\nsize (can be done incrementally later).\n\nPreviously a number of cases in TCP SACK processing fails to\ntake advantage of costly stored information in sack_recv_cache,\nmost importantly, expected events such as cumulative ACK and new\nhole ACKs. Processing on such ACKs result in rather long walks\nbuilding up latencies (which easily gets nasty when window is\nhuge). Those latencies are often completely unnecessary\ncompared with the amount of _new_ information received, usually\nfor cumulative ACK there\u0027s no new information at all, yet TCP\nwalks whole queue unnecessary potentially taking a number of\ncostly cache misses on the way, etc.!\n\nSince the inclusion of highest_sack, there\u0027s a lot information\nthat is very likely redundant (SACK fastpath hint stuff,\nfackets_out, highest_sack), though there\u0027s no ultimate guarantee\nthat they\u0027ll remain the same whole the time (in all unearthly\nscenarios). Take advantage of this knowledge here and drop\nfastpath hint and use direct access to highest SACKed skb as\na replacement.\n\nEffectively \"special cased\" fastpath is dropped. This change\nadds some complexity to introduce better coveraged \"fastpath\",\nthough the added complexity should make TCP behave more cache\nfriendly.\n\nThe current ACK\u0027s SACK blocks are compared against each cached\nblock individially and only ranges that are new are then scanned\nby the high constant walk. For other parts of write queue, even\nwhen in previously known part of the SACK blocks, a faster skip\nfunction is used (if necessary at all). In addition, whenever\npossible, TCP fast-forwards to highest_sack skb that was made\navailable by an earlier patch. In typical case, no other things\nbut this fast-forward and mandatory markings after that occur\nmaking the access pattern quite similar to the former fastpath\n\"special case\".\n\nDSACKs are special case that must always be walked.\n\nThe local to recv_sack_cache copying could be more intelligent\nw.r.t DSACKs which are likely to be there only once but that\nis left to a separate patch.\n\nSigned-off-by: Ilpo Järvinen \u003cilpo.jarvinen@helsinki.fi\u003e\nSigned-off-by: David S.

This assumption is valid because TCPCB_EVER_RETRANS does\nnot leave holes but each non-SACKed segment is rexmitted\nin-order.\n\nCheck for retrans_out \u003e 1 avoids more expensive walk through the\nskb list, as we can know the result beforehand: F-RTO will not be\nallowed.\n\nSACKed skb can turn into non-SACked only in the extremely rare\ncase of SACK reneging, in this case we might fail to detect\nretransmissions if there were them for any other than head. To\nget rid of that feature, whole rexmit queue would have to be\nwalked (always) or FRTO should be prevented when SACK reneging\nhappens. Of course RTO should still trigger after reneging which\nmakes this issue even less likely to show up.
