It further addresses the problems listed below.\n\nThe code looks if the write queue is non-empty and grants the TX CCID up to\n`timeout\u0027 jiffies to drain the queue. It will instead purge that queue if\n * the delay suggested by the CCID exceeds the time budget;\n * a socket error occurred while waiting for the CCID;\n * there is a signal pending (eg. annoyed user pressed Control-C);\n * the CCID does not support delays (we don\u0027t know how long it will take).\n\n\n D e t a i l s [can be removed]\n -------------------------------\nDCCP\u0027s sending mechanism functions a bit like non-blocking I/O: dccp_sendmsg()\nwill enqueue up to net.dccp.default.tx_qlen packets (default\u003d5), without waiting\nfor them to be released to the network.\n\nRate-based CCIDs, such as CCID3/4, can impose sending delays of up to maximally\n64 seconds (t_mbi in RFC 3448). Hence the write queue may still contain packets\nwhen the application closes. Since the write queue is congestion-controlled by\nthe CCID, draining the queue is also under control of the CCID.\n\nThere are several problems that needed to be addressed:\n 1) The queue-drain mechanism only works with rate-based CCIDs. If CCID2 for\n example has a full TX queue and becomes network-limited just as the\n application wants to close, then waiting for CCID2 to become unblocked could\n lead to an indefinite delay (i.e., application \"hangs\").\n 2) Since each TX CCID in turn uses a feedback mechanism, there may be changes\n in its sending policy while the queue is being drained. This can lead to\n further delays during which the application will not be able to terminate.\n 3) The minimum wait time for CCID3/4 can be expected to be the queue length\n times the current inter-packet delay. For example if tx_qlen\u003d100 and a delay\n of 15 ms is used for each packet, then the application would have to wait\n for a minimum of 1.5 seconds before being allowed to exit.\n 4) There is no way for the user/application to control this behaviour. It would\n be good to use the timeout argument of dccp_close() as an upper bound. Then\n the maximum time that an application is willing to wait for its CCIDs to can\n be set via the SO_LINGER option.\n\nThese problems are addressed by giving the CCID a grace period of up to the\n`timeout\u0027 value.\n\nThe wait-for-ccid function is, as before, used when the application \n (a) has read all the data in its receive buffer and\n (b) if SO_LINGER was set with a non-zero linger time, or\n (c) the socket is either in the OPEN (active close) or in the PASSIVE_CLOSEREQ\n state (client application closes after receiving CloseReq).\n\nIn addition, there is a catch-all case by calling __skb_queue_purge() after \nwaiting for the CCID. This is necessary since the write queue may still have\ndata when\n (a) the host has been passively-closed,\n (b) abnormal termination (unread data, zero linger time),\n (c) wait-for-ccid could not finish within the given time limit.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\n" }, { "commit": "2faae5587f692fd5c79856ca4c4b90944ee0472a", "tree": "637536dff5a15b5196233f38066644d19f77f23e", "parents": [ "4861a354430d2ea36847ef88086c7449b4f385b6" ], "author": { "name": "Gerrit Renker", "email": "gerrit@erg.abdn.ac.uk", "time": "Thu Sep 04 07:30:19 2008 +0200" }, "committer": { "name": "Gerrit Renker", "email": "gerrit@erg.abdn.ac.uk", "time": "Thu Sep 04 07:45:32 2008 +0200" }, "message": "dccp ccid-2: Use feature-negotiation to report Ack Ratio changes\n\nThis uses the new feature-negotiation framework to signal Ack Ratio changes,\nas required by RFC 4341, sec. 6.1.2.\n\nThis raises some problems for CCID-2 since it can at the moment not cope\ngracefully with Ack Ratio of e.g. 2.

To make such use explicit, corresponding feature-negotiation\noptions are inserted which signal the use of the loss event rate option,\nas it is used by the CCID3 code.\n\nLastly, the values of the Ack Ratio feature are matched to the choice of CCID.\n\nThe patch implements this as a function which is called after the user has\nmade all other registrations for changing default values of features.\n\nThe table is variable-length, the reserved (and hence for feature-negotiation\ninvalid, confirmed by considering section 19.4 of RFC 4340) feature number `0\u0027\nis used to mark the end of the table.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nAcked-by: Ian McDonald \u003cian.mcdonald@jandi.co.nz\u003e\n" }, { "commit": "71bb49596bbf4e5a3328e1704d18604e822ba181", "tree": "75f64f2f0fea482efc3bdcac407ab187d9e78b5a", "parents": [ "86349c8d9c6892b57aff4549256ab1aa65aed0f0" ], "author": { "name": "Gerrit Renker", "email": "gerrit@erg.abdn.ac.uk", "time": "Thu Sep 04 07:30:19 2008 +0200" }, "committer": { "name": "Gerrit Renker", "email": "gerrit@erg.abdn.ac.uk", "time": "Thu Sep 04 07:45:27 2008 +0200" }, "message": "dccp: Query supported CCIDs\n\nThis provides a data structure to record which CCIDs are locally supported\nand three accessor functions:\n - a test function for internal use which is used to validate CCID requests\n made by the user;\n - a copy function so that the list can be used for feature-negotiation; \n - documented getsockopt() support so that the user can query capabilities.\n\nThe data structure is a table which is filled in at compile-time with the\nlist of available CCIDs (which in turn depends on the Kconfig choices).\n\nUsing the copy function for cloning the list of supported CCIDs is useful for\nfeature negotiation, since the negotiation is now with the full list of available\nCCIDs (e.g. {2, 3}) instead of the default value {2}.

In any other state, the CloseReq is ignored.\n I think that this offers some robustness against rare and pathological cases: e.g. a simultaneous close where\n the client sends a Close and the server a CloseReq. The client will then be retransmitting its Close until it\n gets the Reset, so ignoring the CloseReq while in state CLOSING is sane.\n\n2) Receiving Close\n\n The code below from 8.5 is unconditional.\n\n Step 14: Process Close\n If P.type \u003d\u003d Close,\n Generate Reset(Closed)\n Tear down connection\n Drop packet and return\n\n Thus we need to consider all states:\n * CLOSED: silently ignore, since this can happen when a retransmitted or late Close arrives;\n * LISTEN: dccp_rcv_state_process() will generate a Reset (\"No Connection\");\n * REQUEST: perform Step 14 directly (no need to enqueue packet);\n * RESPOND: dccp_check_req() will generate a Reset (\"Packet Error\") -- left it at that;\n * OPEN/PARTOPEN: enter PASSIVE_CLOSE so that application has a chance to process unread data;\n * CLOSEREQ: server performed active-close -- perform Step 14;\n * CLOSING: simultaneous-close: use a tie-breaker to avoid message ping-pong (see comment);\n * PASSIVE_CLOSEREQ: ignore - the peer has a bug (sending first a CloseReq and now a Close);\n * TIMEWAIT: packet is ignored.\n\n Note that the condition of receiving a packet in state CLOSED here is different from the condition \"there\n is no socket for such a connection\": the socket still exists, but its state indicates it is unusable.\n\n Last, dccp_finish_passive_close sets either DCCP_CLOSED or DCCP_CLOSING \u003d TCP_CLOSING, so that\n sk_stream_wait_close() will wait for the final Reset (which will trigger CLOSING \u003d\u003e CLOSED).\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nSigned-off-by: David S.

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 DCCP_CLOSED in the time being,\nwe know that the socket has been destroyed. Otherwise the socket is\nstill ours to keep.\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.

Since the\nexisting POLLHUP handling, that does not report correctly half-closed\ndevices, was feared to be changed, this implementation leaves the current\nPOLLHUP reporting unchanged and simply add a new bit that is set in the few\nplaces where it makes sense.

As far\nas the existing POLLHUP handling, the patch leaves it as is. The\npollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing\narchs and sets the bit in the six relevant files.
