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.

The\npacket dump shows that most of the packets sent are smaller\nthan a page.\n\nLooking at the code this actually is quite obvious as it always\nstop extending the packet if it\u0027s the first packet yet to be\nsent and if it\u0027s larger than the MSS. Since each extension is\nbound by the page size, this means that (given a 1500 MTU) we\u0027re\nvery unlikely to construct packets greater than a page, provided\nthat the receiver and the path is fast enough so that packets can\nalways be sent immediately.\n\nThe fix is also quite obvious. The push calls inside the loop\nis just an optimisation so that we don\u0027t end up doing all the\nsending at the end of the loop. Therefore there is no specific\nreason why it has to do so at MSS boundaries. For TSO, the\nmost natural extension of this optimisation is to do the pushing\nonce the skb exceeds the TSO size goal.\n\nThis is what the patch does and testing with KVM shows that the\nTSO performance with a 1500 MTU easily surpasses that of a 16436\nMTU and indeed the packet sizes sent are generally larger than\n16436.\n\nI don\u0027t see any obvious downsides for slower peers or connections,\nbut it would be prudent to test this extensively to ensure that\nthose cases don\u0027t regress.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S.
