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.

(we hit a different cache line for the\nrwlock, but then the bucket cache line have a better sharing factor\namong cpus, since we dirty it less often). For netstat or ss commands\nthat want a full scan of hash table, we perform fewer memory accesses.\n\nUsing a \u0027small\u0027 table of hashed rwlocks should be more than enough to\nprovide correct SMP concurrency between different buckets, without\nusing too much memory.

This makes\nreading from /proc/net/tcp pretty slow (well over a second) and as a\nresult netstat is slow on these machines.

The idea is that you have a base type\n(e.g., SKB_GSO_TCPV4) that can be modified further to support new features.\nFor example, if we add a hardware TSO type that supports ECN, they would\ndeclare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would\nhave a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO\npackets would be SKB_GSO_TCPV4.

For example, the inet_diag code holds sk_callback_lock without\ndisabling BH. If an inbound packet arrives during that admittedly tiny\nwindow, it will cause a dead lock on bh_lock_sock. Another possible\npath would be through sock_wfree if the network device driver frees the\ntx skb in process context with BH enabled.\n\nWe can fix this by moving sock_orphan out of bh_lock_sock.\n\nThe tricky bit is to work out when we need to destroy the socket\nourselves and when it has already been destroyed by someone else.\n\nBy moving sock_orphan before the release_sock we can solve this\nproblem. This is because as long as we own the socket lock its\nstate cannot change.\n\nSo we simply record the socket state before the release_sock\nand then check the state again after we regain the socket lock.\nIf the socket state has transitioned to TCP_CLOSE in the time being,\nwe know that the socket has been destroyed. Otherwise the socket is\nstill ours to keep.\n\nNote that I\u0027ve also moved the increment on the orphan count forward.\nThis may look like a problem as we\u0027re increasing it even if the socket\nis just about to be destroyed where it\u0027ll be decreased again. However,\nthis simply enlarges a window that already exists. This also changes\nthe orphan count test by one.\n\nConsidering what the orphan count is meant to do this is no big deal.\n\nThis problem was discoverd by Ingo Molnar using his lock validator.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S.
