This value was\nexported via a SOL_PACKET level cmsg. AFter I completed that work it was\nrequested that this feature be generalized so that any datagram oriented socket\ncould make use of this option. As such I\u0027ve created this patch, It creates a\nnew SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a\nSOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue\noverflowed between any two given frames. It also augments the AF_PACKET\nprotocol to take advantage of this new feature (as it previously did not touch\nsk-\u003esk_drops, which this patch uses to record the overflow count). Tested\nsuccessfully by me.\n\nNotes:\n\n1) Unlike my previous patch, this patch simply records the sk_drops value, which\nis not a number of drops between packets, but rather a total number of drops.\nDeltas must be computed in user space.\n\n2) While this patch currently works with datagram oriented protocols, it will\nalso be accepted by non-datagram oriented protocols. I\u0027m not sure if thats\nagreeable to everyone, but my argument in favor of doing so is that, for those\nprotocols which aren\u0027t applicable to this option, sk_drops will always be zero,\nand reporting no drops on a receive queue that isn\u0027t used for those\nnon-participating protocols seems reasonable to me. This also saves us having\nto code in a per-protocol opt in mechanism.\n\n3) This applies cleanly to net-next assuming that commit\n977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\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.

When a headerless skb is cloned skb-\u003ehdr_len\nis set to the current headroom, for regular clones it is copied from\nthe original. A new function skb_clone_writable(skb, len) returns\nwhether the skb is writable up to len bytes from skb-\u003edata. To avoid\nenlarging the skb the mac_len field is reduced to 16 bit and the\nnew hdr_len field is put in the remaining 16 bit.\n\nI\u0027ve done a few rough benchmarks of NAT (not with this exact patch,\nbut a very similar one). As expected it saves huge amounts of system\ntime in case of sendfile, bringing it down to basically the same\namount as without NAT, with sendmsg it only helps on loopback,\nprobably because of the large MTU.\n\nTransmit a 1GB file using sendfile/sendmsg over eth0/lo with and\nwithout NAT:\n\n- sendfile eth0, no NAT:\tsys 0m0.388s\n- sendfile eth0, NAT:\t\tsys 0m1.835s\n- sendfile eth0: NAT + path:\tsys 0m0.370s\t(~ -80%)\n\n- sendfile lo, no NAT:\t\tsys 0m0.258s\n- sendfile lo, NAT:\t\tsys 0m2.609s\n- sendfile lo, NAT + patch:\tsys 0m0.260s\t(~ -90%)\n\n- sendmsg eth0, no NAT:\t\tsys 0m2.508s\n- sendmsg eth0, NAT:\t\tsys 0m2.539s\n- sendmsg eth0, NAT + patch:\tsys 0m2.445s\t(no change)\n\n- sendmsg lo, no NAT:\t\tsys\t0m2.151s\n- sendmsg lo, NAT:\t\tsys 0m3.557s\n- sendmsg lo, NAT + patch:\tsys 0m2.159s\t(~ -40%)\n\nI expect other users can see a similar performance improvement,\npacket mangling iptables targets, ipip and ip_gre come to mind ..\n\nSigned-off-by: Patrick McHardy \u003ckaber@trash.net\u003e\nSigned-off-by: David S.
