If CCID-2 for\n example has a full TX queue and becomes network-limited just as the\n application wants to close, then waiting for CCID-2 to become unblocked\n could 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 CCID-3/4 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 of __skb_queue_purge() after waiting for\nthe CCID. This is necessary since the write queue may still have data 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\nSigned-off-by: David S.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "c720c7e8383aff1cb219bddf474ed89d850336e3", "tree": "4f12337e6690fccced376db9f501eaf98614a65e", "parents": [ "988ade6b8e27e79311812f83a87b5cea11fabcd7" ], "author": { "name": "Eric Dumazet", "email": "eric.dumazet@gmail.com", "time": "Thu Oct 15 06:30:45 2009 +0000" }, "committer": { "name": "David S.

If both Acks get\n lost, it is probably better to restart the connection anyway and devising yet\n another special-case does not seem worth the extra complexity.\n\nThe result is a higher utilisation of the available packet space for the data\ntransmission phase (established state) of a connection.\n\nThe patch (over-)estimates the initial overhead to be 32*4 bytes -- commonly\nseen values were around 90 bytes for initial feature-negotiation options.\n\nIt uses sizeof(u32) to mean \"aligned units of 4 bytes\".\nFor consistency, another use of 4-byte alignment is adapted.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nSigned-off-by: David S.

Most notably, this is the Send Ack Vector\nfeature, but also Ack Ratio and Send Loss Event Rate (also taken care of).\n\nFor Send Ack Vector, the situation is as follows:\n * since CCID2 mandates the use of Ack Vectors, there is no point in allowing \n endpoints which use CCID2 to disable Ack Vector features such a connection;\n\n * a peer with a TX CCID of CCID2 will always expect Ack Vectors, and a peer\n with a RX CCID of CCID2 must always send Ack Vectors (RFC 4341, sec. 4);\n\n * for all other CCIDs, the use of (Send) Ack Vector is optional and thus\n negotiable. However, this implies that the code negotiating the use of Ack\n Vectors also supports it (i.e. is able to supply and to either parse or\n ignore received Ack Vectors). Since this is not the case (CCID-3 has no Ack\n Vector support), the use of Ack Vectors is here disabled, with a comment\n in the source code.\n\nAn analogous consideration arises for the Send Loss Event Rate feature,\nsince the CCID-3 implementation does not support the loss interval options\nof RFC 4342. 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\nSigned-off-by: David S.
