      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  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"

      "message": "dccp: Clean up slow-path input processing\n\nThis patch rearranges the order of statements of the slow-path input processing\n(i.e. any other state than OPEN), to resolve the following issues.\n\n 1. Dependencies: the order of statements now better matches RFC 4340, 8.5, i.e.\n    step 7 is before step 9 (previously 9 was before 7), and parsing options in\n    step 8 (which can consume resources) now comes after step 7.\n 2. Bug-fix: in state CLOSED, there should not be any sequence number checking\n    or option processing. This is why the test for CLOSED has been moved after\n    the test for LISTEN.\n 3. As before sequence number checks are omitted if in state LISTEN/REQUEST, due\n    to the note underneath the table in RFC 4340, 7.5.3.\n 4. Packets are now passed on to Ack Vector / CCID processing only after\n    - step 7  (receive unexpected packets), \n    - step 9  (receive Reset),\n    - step 13 (receive CloseReq),\n    - step 14 (receive Close)\n    and only if the state is PARTOPEN. This simplifies CCID processing:\n    - in LISTEN/CLOSED the CCIDs are non-existent;\n    - in RESPOND/REQUEST the CCIDs have not yet been negotiated;\n    - in CLOSEREQ and active-CLOSING the node has already closed this socket;\n    - in passive-CLOSING the client is waiting for its Reset.\n    In the last case, RFC 4340, 8.3 leaves it open to ignore further incoming\n    data, which is the approach taken here.\n\nAs a result of (3), CCID processing is now indeed confined to OPEN/PARTOPEN\nstates, i.e. congestion control is performed only on the flow of data packets. \n\nThis avoids pathological cases of doing congestion control on those messages\nwhich set up and terminate the connection. \n\nI have done a few checks to see if this creates a problem in other parts of\nthe code. This seems not to be the case; even if there were one, it would be\nbetter to fix it than to perform congestion control on Close/Request/Response\nmessages. Similarly for Ack Vectors (as they depend on the negotiated CCID).\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\n"

      "message": "dccp ccid-2: Algorithm to update buffer state\n\nThis provides a routine to consistently update the buffer state when the\npeer acknowledges receipt of Ack Vectors; updating state in the list of Ack\nVectors as well as in the circular buffer.\n\nWhile based on RFC 4340, several additional (and necessary) precautions were\nadded to protect the consistency of the buffer state. These additions are\nessential, since analysis and experience showed that the basic algorithm was\ninsufficient for this task (which lead to problems that were hard to debug).\n\nThe algorithm now\n * deals with HC-sender acknowledging to HC-receiver and vice versa,\n * keeps track of the last unacknowledged but received seqno in tail_ackno,\n * has special cases to reset the overflow condition when appropriate,\n * is protected against receiving older information (would mess up buffer state).\n\nNote: The older code performed an unnecessary step, where the sender cleared\nAck Vector state by parsing the Ack Vector received by the HC-receiver. Doing\nthis was entirely redundant, since\n * the receiver always puts the full acknowledgment window (groups 2,3 in 11.4.2)\n   into the Ack Vectors it sends; hence the HC-receiver is only interested in the\n   highest state that the HC-sender received;\n * this means that the acknowledgment number on the (Data)Ack from the HC-sender\n   is sufficient; and work done in parsing earlier state is not necessary, since\n   the later state subsumes the  earlier one (see also RFC 4340, A.4).\nThis older interface (dccp_ackvec_parse()) is therefore removed.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\n"

      "message": "dccp ccid-2: Ack Vector interface clean-up\n\nThis patch brings the Ack Vector interface up to date. Its main purpose is\nto lay the basis for the subsequent patches of this set, which will use the\nnew data structure fields and routines.\n\nThere are no real algorithmic changes, rather an adaptation:\n\n (1) Replaced the static Ack Vector size (2) with a #define so that it can\n     be adapted (with low loss / Ack Ratio, a value of 1 works, so 2 seems\n     to be sufficient for the moment) and added a solution so that computing\n     the ECN nonce will continue to work - even with larger Ack Vectors.\n\n (2) Replaced the #defines for Ack Vector states with a complete enum.\n\n (3) Replaced #defines to compute Ack Vector length and state with general\n     purpose routines (inlines), and updated code to use these.\n\n (4) Added a `tail\u0027 field (conversion to circular buffer in subsequent patch).\n\n (5) Updated the (outdated) documentation for Ack Vector struct.\n\n (6) All sequence number containers now trimmed to 48 bits.\n\n (7) Removal of unused bits:\n     * removed dccpav_ack_nonce from struct dccp_ackvec, since this is already\n       redundantly stored in the `dccpavr_ack_nonce\u0027 (of Ack Vector record);\n     * removed Elapsed Time for Ack Vectors (it was nowhere used);\n     * replaced semantics of dccpavr_sent_len with dccpavr_ack_runlen, since\n       the code needs to be able to remember the old run length; \n     * reduced the de-/allocation routines (redundant / duplicate tests).\n\n\nJustification for removing Elapsed Time information [can be removed]:\n---------------------------------------------------------------------\n 1. The Elapsed Time information for Ack Vectors was nowhere used in the code.\n 2. DCCP does not implement rate-based pacing of acknowledgments. The only\n    recommendation for always including Elapsed Time is in section 11.3 of\n    RFC 4340: \"Receivers that rate-pace acknowledgements SHOULD [...]\n    include Elapsed Time options\". But such is not the case here.\n 3. It does not really improve estimation accuracy. The Elapsed Time field only\n    records the time between the arrival of the last acknowledgeable packet and\n    the time the Ack Vector is sent out. Since Linux does not (yet) implement\n    delayed Acks, the time difference will typically be small, since often the\n    arrival of a data packet triggers sending feedback at the HC-receiver.\n\n\nJustification for changes in de-/allocation routines [can be removed]:\n----------------------------------------------------------------------\n  * INIT_LIST_HEAD in dccp_ackvec_record_new was redundant, since the list\n    pointers were later overwritten when the node was added via list_add();\n  * dccp_ackvec_record_new() was called in a single place only;\n  * calls to list_del_init() before calling dccp_ackvec_record_delete() were\n    redundant, since subsequently the entire element was k-freed;\n  * since all calls to dccp_ackvec_record_delete() were preceded to a call to\n    list_del_init(), the WARN_ON test would never evaluate to true;\n  * since all calls to dccp_ackvec_record_delete() were made from within\n    list_for_each_entry_safe(), the test for avr \u003d\u003d NULL was redundant;\n  * list_empty() in ackvec_free was redundant, since the same condition is\n    embedded in the loop condition of the subsequent list_for_each_entry_safe().\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\n"

      "message": "dccp: Fix the adjustments to AWL and SWL\n\nThis fixes a problem and a potential loophole with regard to seqno/ackno\nvalidity: the problem is that the initial adjustments to AWL/SWL were\nonly performed at the begin of the connection, during the handshake.\n\nSince the Sequence Window feature is always greater than Wmin\u003d32 (7.5.2), \nit is however necessary to perform these adjustments at least for the first\nW/W\u0027 (variables as per 7.5.1) packets in the lifetime of a connection.\n\nThis requirement is complicated by the fact that W/W\u0027 can change at any time\nduring the lifetime of a connection.\n\nTherefore the consequence is to perform this safety check each time SWL/AWL\nare updated.\n\nA second problem solved by this patch is that the remote/local Sequence Window\nfeature values (which set the bounds for AWL/SWL/SWH) are undefined until the\nfeature negotiation has completed.\n\nDuring the initial handshake we have more stringent sequence number protection,\nthe changes added by this patch effect that {A,S}W{L,H} are within the correct\nbounds at the instant that feature negotiation completes (since the SeqWin\nfeature activation handlers call dccp_update_gsr/gss()). \n\nA detailed rationale is below -- can be removed from the commit message.\n\n\n1. Server sequence number checks during initial handshake\n---------------------------------------------------------\nThe server can not use the fields of the listening socket for seqno/ackno checks\nand thus needs to store all relevant information on a per-connection basis on\nthe dccp_request socket. This is a size-constrained structure and has currently\nonly ISS (dreq_iss) and ISR (dreq_isr) defined.\nAdding further fields (SW{L,H}, AW{L,H}) would increase the size of the struct\nand it is questionable whether this will have any practical gain. The currently\nimplemented solution is as follows.\n * receiving first Request: dccp_v{4,6}_conn_request sets \n                            ISR :\u003d P.seqno, ISS :\u003d dccp_v{4,6}_init_sequence()\n\n * sending first Response:  dccp_v{4,6}_send_response via dccp_make_response()\t\n                            sets P.seqno :\u003d ISS, sets P.ackno :\u003d ISR\n\n * receiving retransmitted Request: dccp_check_req() overrides ISR :\u003d P.seqno\n\n * answering retransmitted Request: dccp_make_response() sets ISS +\u003d 1,\n                                    otherwise as per first Response\n\n * completing the handshake: succeeds in dccp_check_req() for the first Ack\n                             where P.ackno \u003d\u003d ISS (P.seqno is not tested)\n\n * creating child socket: ISS, ISR are copied from the request_sock\n\nThis solution will succeed whenever the server can receive the Request and the\nsubsequent Ack in succession, without retransmissions. If there is packet loss,\nthe client needs to retransmit until this condition succeeds; it will otherwise\neventually give up. Adding further fields to the request_sock could increase\nthe robustness a bit, in that it would make possible to let a reordered Ack\n(from a retransmitted Response) pass. The argument against such a solution is\nthat if the packet loss is not persistent and an Ack gets through, why not\nwait for the one answering the original response: if the loss is persistent, it\nis probably better to not start the connection in the first place.\n\nLong story short: the present design (by Arnaldo) is simple and will likely work\njust as well as a more complicated solution. As a consequence, {A,S}W{L,H} are\nnot needed until the moment the request_sock is cloned into the accept queue.\n\nAt that stage feature negotiation has completed, so that the values for the local\nand remote Sequence Window feature (7.5.2) are known, i.e. we are now in a better\nposition to compute {A,S}W{L,H}.\n\n\n2. Client sequence number checks during initial handshake\n---------------------------------------------------------\nUntil entering PARTOPEN the client does not need the adjustments, since it \nconstrains the Ack window to the packet it sent.\n\n * sending first Request: dccp_v{4,6}_connect() choose ISS, \n                          dccp_connect() then sets GAR :\u003d ISS (as per 8.5),\n\t\t\t  dccp_transmit_skb() (with the previous bug fix) sets\n\t\t\t         GSS :\u003d ISS, AWL :\u003d ISS, AWH :\u003d GSS\n * n-th retransmitted Request (with previous patch):\n\t                  dccp_retransmit_skb() via timer calls\n\t\t\t  dccp_transmit_skb(), which sets GSS :\u003d ISS+n\n                          and then AWL :\u003d ISS, AWH :\u003d ISS+n\n\t                  \n * receiving any Response: dccp_rcv_request_sent_state_process() \n\t                   -- accepts packet if AWL \u003c\u003d P.ackno \u003c\u003d AWH;\n\t\t\t   -- sets GSR \u003d ISR \u003d P.seqno\n\n * sending the Ack completing the handshake: dccp_send_ack() calls \n                           dccp_transmit_skb(), which sets GSS +\u003d 1\n\t\t\t   and AWL :\u003d ISS, AWH :\u003d GSS\n\t\t\t   \n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\n"

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.

Hence SHUT_WR is honoured only after the last\n   packet (under congestion control) has been sent;\n * although SHUT_RDWR seems nonsensical, it is nevertheless supported in the same manner\n   as for TCP (and agrees with test for SHUTDOWN_MASK in dccp_poll() in net/dccp/proto.c).\n\nFurthermore, most of the code already honours the sk_shutdown flags (dccp_recvmsg() for\ninstance sets the read length to 0 if SHUT_RD had been called); CCID handling is now added\nto this by the present patch.\n\nThere will also no longer be any delivery when the socket is in the final stages, i.e. when\none of dccp_close(), dccp_fin(), or dccp_done() has been called - which is fine since at\nthat stage the connection is its final stages.\n\nMotivation and background are on http://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/shutdown\n\nA FIXME has been added to notify the other end if SHUT_RD has been set (RFC 4340, 11.7).\n\nNote: There is a comment in inet_shutdown() in net/ipv4/af_inet.c which asks to \"make\n      sure the socket is a TCP socket\".

This is a more stringent\npolicy than enforcing the rate-limit on a per-source-address basis and\nprotects against attacks with forged source addresses.\n\nMoreover, the mechanism is deliberately kept simple. In contrast to\nxrlim_allow(), bursts of Sync packets in reply to sequence-invalid packets\nare not supported.  This foils such attacks where the receipt of a Sync\ntriggers further sequence-invalid packets. (I have tested this mechanism against\nxrlim_allow algorithm for Syncs, permitting bursts just increases the problems.)\n\nIn order to keep flexibility, the timeout parameter can be set via sysctl; and\nthe whole mechanism can even be disabled (which is however not recommended).\n\nThe algorithm in this patch has been improved with regard to wrapping issues\nthanks to a suggestion by Arnaldo.\n\nCommiter note: Rate limited the step 6 DCCP_WARN too, as it says we\u0027re\n               sending a sync.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nSigned-off-by: Ian McDonald \u003cian.mcdonald@jandi.co.nz\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\n"

This causes the\nReset sent by the client in (6) to become sequence-valid, so that in (7)\nthe vicious circle is broken; the Reset is then enqueued and causes the\nsocket to enter TIMEWAIT state.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nSigned-off-by: Ian McDonald \u003cian.mcdonald@jandi.co.nz\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\nSigned-off-by: David S.
