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.

The minimum RTO of previously one second has been replaced with TCP\u0027s, since\n RFC4341, sec. 5 says that the minimum of 1 sec. (suggested in RFC2988, 2.4)\n is not necessary. Instead, the TCP_RTO_MIN is used, which agrees with DCCP\u0027s\n concept of a default RTT (RFC 4340, 3.4).\n 2. The maximum RTO has been set to DCCP_RTO_MAX (64 sec), which agrees with\n RFC2988, (2.5).\n 3. De-inlined the function ccid2_new_ack().\n 4. Added a FIXME: the RTT is sampled several times per Ack Vector, which will\n give the wrong estimate. It should be replaced with one sample per Ack.\n However, at the moment this can not be resolved easily, since\n - it depends on TX history code (which also needs some work),\n - the cleanest solution is not to use the `sent\u0027 time at all (saves 4 bytes\n per entry) and use DCCP timestamps / elapsed time to estimated the RTT,\n which however is non-trivial to get right (but needs to be done).\n\nReasons for reusing the Linux TCP estimator algorithm:\n------------------------------------------------------\nSome time was spent to find a better alternative, using basic RFC2988 as a first\nstep. Further analysis and experimentation showed that the Linux TCP RTO\nestimator is superior to a basic RFC2988 implementation. A summary is on\nhttp://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/ccid2/rto_estimator/\n\nIn addition, this estimator fared well in a recent empirical evaluation:\n\n Rewaskar, Sushant, Jasleen Kaur and F. Donelson Smith.\n A Performance Study of Loss Detection/Recovery in Real-world TCP\n Implementations. Proceedings of 15th IEEE International\n Conference on Network Protocols (ICNP-07), 2007.\n\nThus there is significant benefit in reusing the existing TCP code.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nSigned-off-by: David S.

When head \u003d\u003d tail (TX history empty) then pipe\nshould be 0, which is the case directly after initialisation and after a\nretransmission timeout has occurred (ccid2_hc_tx_rto_expire).\n\nThe first case involves parsing Ack Vectors for packets recorded in the live\nportion of the buffer, between tail and head. For each packet marked by the\nreceiver as received (state 0) or ECN-marked (state 1), pipe is decremented by\none, so for all such packets the BUG_ON in tx_check_sanity will not trigger.\n\nThe second case is the loss detection in the second half of tx_packet_recv,\nbelow the comment \"Check for NUMDUPACK\".\n\nThe first while-loop here ensures that the sequence number of `seqp\u0027 is either\nabove or equal to `high_ack\u0027, or otherwise equal to the highest sequence number\nsent so far (of the entry head-\u003eprev, as head points to the next unsent entry).\nThe next while-loop (\"while (1)\") counts the number of acked packets starting\nfrom that position of seqp, going backwards in the direction from head-\u003eprev to\ntail. If NUMDUPACK\u003d3 such packets were counted within this loop, `seqp\u0027 points\nto the last acknowledged packet of these, and the \"if (done \u003d\u003d NUMDUPACK)\" block\nis entered next.\nThe while-loop contained within that block in turn traverses the list backwards,\nfrom head to tail; the position of `seqp\u0027 is saved in the variable `last_acked\u0027.\nFor each packet not marked as `acked\u0027, a congestion event is triggered within\nthe loop, and pipe is decremented. The loop terminates when `seqp\u0027 has reached\n`tail\u0027, whereupon tail is set to the position previously stored in `last_acked\u0027.\nThus, between `last_acked\u0027 and the previous position of `tail\u0027,\n - pipe has been decremented earlier if the packet was marked as state 0 or 1;\n - pipe was decremented if the packet was not marked as acked.\nThat is, pipe has been decremented by the number of packets between `last_acked\u0027\nand the previous position of `tail\u0027. As a consequence, pipe now again reflects\nthe number of packets which have not (yet) been acked between the new position\nof tail (at `last_acked\u0027) and head-\u003eprev, or 0 if head\u003d\u003dtail. The result is that\nthe BUG_ON condition in check_sanity will also not be triggered, hence the test\n(3) is also redundant.\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.

The bug halt occured because the page\nthat I passed to kfree failed the PageCompound and PageSlab test in the slub\nimplementation of kfree. I tracked the problem down to the following set of\nevents:\n\n1) dccp, unlike all other uses of kmem_cache_create, allocates a string\ndynamically when registering a slab cache. This allocated string is freed when\nthe cache is destroyed.\n\n2) Normally, (1) is not an issue, but when Slub is in use, it is possible that\ncaches are \u0027merged\u0027. This process causes multiple caches of simmilar\nconfiguration to use the same cache data structure. When this happens, the new\nname of the cache is effectively dropped.\n\n3) (2) results in kmem_cache_name returning an ambigous value (i.e.\nccid_kmem_cache_destroy, which uses this fuction to retrieve the name pointer\nfor freeing), is no longer guaranteed that the string it assigned is what is\nreturned.\n\n4) If such merge event occurs, ccid_kmem_cache_destroy frees the wrong pointer,\nwhich trips over the BUG in the slub implementation of kfree (since its likely\nnot a slab allocation, but rather a pointer into the static string table\nsection.\n\nSo, what to do about this. At first blush this is pretty clearly a leak in the\ninformation that slub owns, and as such a slub bug. Unfortunately, theres no\nreally good way to fix it, without exposing slub specific implementation details\nto the generic slab interface. Also, even if we could fix this in slub cleanly,\nI think the RCU free option would force us to do lots of string duplication, not\nonly in slub, but in every slab allocator. As such, I\u0027d like to propose this\nsolution. Basically, I just move the storage for the kmem cache name to the\nccid_operations structure. In so doing, we don\u0027t have to do the kstrdup or\nkfree when we allocate/free the various caches for dccp, and so we avoid the\nproblem, by storing names with static memory, rather than heap, the way all\nother calls to kmem_cache_create do.\n\nI\u0027ve tested this out myself here, and it solves the problem quite well.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nAcked-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nSigned-off-by: David S.

Only 17 files in the current 2.6.31-rc5 used it.\nFIFO\u0027s are like list\u0027s a very basic thing and a kfifo API which handles\nthe most use case would save a lot of development time and memory\nresources.\n\nI think this are the reasons why kfifo is not in use:\n\n - The API is to simple, important functions are missing\n - A fifo can be only allocated dynamically\n - There is a requirement of a spinlock whether you need it or not\n - There is no support for data records inside a fifo\n\nSo I decided to extend the kfifo in a more generic way without blowing up\nthe API to much. The new API has the following benefits:\n\n - Generic usage: For kernel internal use and/or device driver.\n - Provide an API for the most use case.\n - Slim API: The whole API provides 25 functions.\n - Linux style habit.\n - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros\n - Direct copy_to_user from the fifo and copy_from_user into the fifo.\n - The kfifo itself is an in place member of the using data structure, this save an\n indirection access and does not waste the kernel allocator.\n - Lockless access: if only one reader and one writer is active on the fifo,\n which is the common use case, no additional locking is necessary.\n - Remove spinlock - give the user the freedom of choice what kind of locking to use if\n one is required.\n - Ability to handle records. Three type of records are supported:\n - Variable length records between 0-255 bytes, with a record size\n field of 1 bytes.\n - Variable length records between 0-65535 bytes, with a record size\n field of 2 bytes.\n - Fixed size records, which no record size field.\n - Preserve memory resource.\n - Performance!\n - Easy to use!\n\nThis patch:\n\nSince most users want to have the kfifo as part of another object,\nreorganize the code to allow including struct kfifo in another data\nstructure. This requires changing the kfifo_alloc and kfifo_init\nprototypes so that we pass an existing kfifo pointer into them.
