I agree with Andrea\u0027s comment\nthat there is a problem here but the way it is treated does not fix it.\n\nThe problem is that whenever Ack Ratio \u003e cwnd, starvation/deadlock occurs:\n * the receiver will not send an Ack until (Ack Ratio - cwnd) data packets\n have arrived;\n * the sender will not send any data packet before the receipt of an Ack\n advances the send window.\nThe only way that the connection then progresses was via RTO timeout. In one\nextreme case (bulk transfer), it was observed that this happened for every single\npacket; i.e. hundreds of packets, each a RTO timeout of 1..3 seconds apart:\na transfer which normally would take a fraction of a second thus grew to\nseveral minutes.\n\nThe solution taken by this approach is to observe the relation\n\n \"Ack Ratio \u003c\u003d cwnd\"\n\nby using the constraint (1) from RFC 4341, 6.1.2; i.e. set\n\n Ack Ratio \u003d ceil(cwnd / 2)\n\nand update it whenever either Ack Ratio or cwnd change.

DCCP relies for its proper functioning on having at least one CCID module\n enabled (as in TCP plugable congestion control). Currently it is possible to\n disable both CCIDs and thus leave the DCCP module in a compiled, but entirely\n non-functional state: no sockets can be created when no CCID is available.\n Furthermore, the protocol is (again like TCP) not intended to be used without\n CCIDs. Last, a non-empty CCID list is needed for doing CCID feature negotiation.\n\n 2. Internally the default CCID that is advertised by the Linux host is set to CCID2\n (DCCPF_INITIAL_CCID in include/linux/dccp.h). Disabling CCID2 in the Kconfig\n menu without changing the defaults leads to a failure `module not found\u0027 when\n trying to load the dccp module (which internally tries to load the default CCID).\n\n 3. The specification (RFC 4340, sec. 10) treats CCID2 somewhat like a\n `minimum common denominator\u0027; the specification says that:\n\n * \"New connections start with CCID 2 for both endpoints\"\n\n * \"A DCCP implementation intended for general use, such as an implementation in a\n general-purpose operating system kernel, SHOULD implement at least CCID 2.\n The intent is to make CCID 2 broadly available for interoperability [...]\"\n\n Providing CCID2 as minimum-required CCID (like Reno/Cubic in TCP) thus seems reasonable.\n\nHence this patch automatically selects CCID2 when DCCP is enabled.

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.

FACK\nimplementation is based on such assumptions. Previously (before\nthe rewrite) the non-FACK SACK was basically doing fast rexmit\nand then it times out all skbs when first cumulative ACK arrives,\nwhich cannot really be called SACK based recovery :-).\n\nRFC3517 SACK disables these things:\n- Per SKB timeouts \u0026 head timeout entry to recovery\n- Marking at least one skb while in recovery (RFC3517 does this\n only for the fast retransmission but not for the other skbs\n when cumulative ACKs arrive in the recovery)\n- Sacktag\u0027s loss detection flavors B and C (see comment before\n tcp_sacktag_write_queue)\n\nThis does not implement the \"last resort\" rule 3 of NextSeg, which\nallows retransmissions also when not enough SACK blocks have yet\narrived above a segment for IsLost to return true [RFC3517].\n\nThe implementation differs from RFC3517 in these points:\n- Rate-halving is used instead of FlightSize / 2\n- Instead of using dupACKs to trigger the recovery, the number\n of SACK blocks is used as FACK does with SACK blocks+holes\n (which provides more accurate number). It seems that the\n difference can affect negatively only if the receiver does not\n generate SACK blocks at all even though it claimed to be\n SACK-capable.\n- Dupthresh is not a constant one. Dynamical adjustments include\n both holes and sacked segments (equal to what FACK has) due to\n complexity involved in determining the number sacked blocks\n between highest_sack and the reordered segment. Thus it\u0027s will\n be an over-estimate.\n\nImplementation note:\n\ntcp_clean_rtx_queue doesn\u0027t need a lost_cnt tweak because head\nskb at that point cannot be SACKED_ACKED (nor would such\nsituation last for long enough to cause problems).\n\nSigned-off-by: Ilpo Järvinen \u003cilpo.jarvinen@helsinki.fi\u003e\nSigned-off-by: David S.
