At each read operation, a seek is done to find the\nlast socket that was previously read. This seek operation requires\nthat the sockets in the table need to be counted up to the current\nfile position, and to count each of these requires taking a lock for\neach non-empty bucket. The whole algorithm is O(n^2).\n\nThe fix is to cache the last bucket value, offset within the bucket,\nand the file position returned by the last read operation. On the\nnext sequential read, the bucket and offset are used to find the\nlast read socket immediately without needing ot scan the previous\nbuckets the table. This algorithm t read the whole table is O(n).\n\nThe improvement offered by this patch is easily show by performing\ncat\u0027ing /proc/net/tcp on a machine with a lot of connections.

This is the case, because the RTO schedule follows a fixed\npattern, namely exponential backoff.\n\nHowever, the RTO behaviour is not predictable any more if RTO backoffs can be\nreverted, as it is the case in the draft\n\"Make TCP more Robust to Long Connectivity Disruptions\"\n(http://tools.ietf.org/html/draft-zimmermann-tcp-lcd).\n\nIn the worst case TCP would time out a connection after 3.2 seconds, if the\ninitial RTO equaled MIN_RTO and each backoff has been reverted.\n\nThis patch introduces a function retransmits_timed_out(N),\nwhich calculates the timeout of a TCP connection, assuming an initial\nRTO of MIN_RTO and N unsuccessful, exponentially backed-off retransmissions.\n\nWhenever timeout decisions are made by comparing the retransmission counter\nto some value N, this function can be used, instead.\n\nThe meaning of tcp_retries2 will be changed, as many more RTO retransmissions\ncan occur than the value indicates. However, it yields a timeout which is\nsimilar to the one of an unpatched, exponentially backing off TCP in the same\nscenario. As no application could rely on an RTO greater than MIN_RTO, there\nshould be no risk of a regression.\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.

Try to return back to pre-split\nstate already while more and more SACK info gets discovered by\ncombining newly discovered SACK areas with the previous skb if\nthat\u0027s SACKed as well.\n\nThis approach has a number of benefits:\n\n1) The processing overhead is spread more equally over the RTT\n2) Write queue has less skbs to process (affect everything\n which has to walk in the queue past the sacked areas)\n3) Write queue is consistent whole the time, so no other parts\n of TCP has to be aware of this (this was not the case with\n some other approach that was, well, quite intrusive all\n around).\n4) Clean_rtx_queue can release most of the pages using single\n put_page instead of previous PAGE_SIZE/mss+1 calls\n\nIn case a hole is fully filled by the new SACK block, we attempt\nto combine the next skb too which allows construction of skbs\nthat are even larger than what tso split them to and it handles\nhole per on every nth patterns that often occur during slow start\novershoot pretty nicely. Though this to be really useful also\na retransmission would have to get lost since cumulative ACKs\nadvance one hole at a time in the most typical case.\n\nTODO: handle upwards only merging. That should be rather easy\nwhen segment is fully sacked but I\u0027m leaving that as future\nwork item (it won\u0027t make very large difference anyway since\nthis current approach already covers quite a lot of normal\ncases).\n\nI was earlier thinking of some sophisticated way of tracking\ntimestamps of the first and the last segment but later on\nrealized that it won\u0027t be that necessary at all to store the\ntimestamp of the last segment. The cases that can occur are\nbasically either:\n 1) ambiguous \u003d\u003e no sensible measurement can be taken anyway\n 2) non-ambiguous is due to reordering \u003d\u003e having the timestamp\n of the last segment there is just skewing things more off\n than does some good since the ack got triggered by one of\n the holes (besides some substle issues that would make\n determining right hole/skb even harder problem). Anyway,\n it has nothing to do with this change then.\n\nI choose to route some abnormal looking cases with goto noop,\nsome could be handled differently (eg., by stopping the\nwalking at that skb but again). In general, they either\nshouldn\u0027t happen at all or are rare enough to make no difference\nin practice.\n\nIn theory this change (as whole) could cause some macroscale\nregression (global) because of cache misses that are taken over\nthe round-trip time but it gets very likely better because of much\nless (local) cache misses per other write queue walkers and the\nbig recovery clearing cumulative ack.\n\nWorth to note that these benefits would be very easy to get also\nwithout TSO/GSO being on as long as the data is in pages so that\nwe can merge them. Currently I won\u0027t let that happen because\nDSACK splitting at fragment that would mess up pcounts due to\nsk_can_gso in tcp_set_skb_tso_segs.

The new function\nadded by this code, tcp_defer_accept_check(), only has the\nchild socket locked, yet it is modifying state of the parent\nlistening socket.\n\nFixing that is non-trivial at best, because we can\u0027t simply just grab\nthe parent listening socket lock at this point, because it would\ncreate an ABBA deadlock. The normal ordering is parent listening\nsocket --\u003e child socket, but this code path would require the\nreverse lock ordering.\n\nNext is a problem noticed by Vitaliy Gusev, he noted:\n\n----------------------------------------\n\u003e--- a/net/ipv4/tcp_timer.c\n\u003e+++ b/net/ipv4/tcp_timer.c\n\u003e@@ -481,6 +481,11 @@ static void tcp_keepalive_timer (unsigned long data)\n\u003e \t\tgoto death;\n\u003e \t}\n\u003e\n\u003e+\tif (tp-\u003edefer_tcp_accept.request \u0026\u0026 sk-\u003esk_state \u003d\u003d TCP_ESTABLISHED) {\n\u003e+\t\ttcp_send_active_reset(sk, GFP_ATOMIC);\n\u003e+\t\tgoto death;\n\nHere socket sk is not attached to listening socket\u0027s request queue. tcp_done()\nwill not call inet_csk_destroy_sock() (and tcp_v4_destroy_sock() which should\nrelease this sk) as socket is not DEAD. Therefore socket sk will be lost for\nfreeing.\n----------------------------------------\n\nFinally, Alexey Kuznetsov argues that there might not even be any\nreal value or advantage to these new semantics even if we fix all\nof the bugs:\n\n----------------------------------------\nHiding from accept() sockets with only out-of-order data only\nis the only thing which is impossible with old approach. Is this really\nso valuable? My opinion: no, this is nothing but a new loophole\nto consume memory without control.\n----------------------------------------\n\nSo revert this thing for now.\n\nSigned-off-by: David S.
