      "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"

This would overwrite\n     some or all of the kernel buffer\n   - copy kernel (LLD) buffer back to the user space.\n\nThe idea was to detect short reads by filling the original\nuser space buffer with some marker bytes (\"0xec\" it would\nseem in this report). The \"resid\" value is a better way\nof detecting short reads but that was only added this century\nand requires co-operation from the LLD.\n\u003d\n\nThis patch changes the block layer mapping API to support this\nsemantics. This simply adds another field to struct rq_map_data and\nenables __bio_copy_iov() to copy data from user space even with READ\nrequests.\n\nIt\u0027s better to add the flags field and kills null_mapped and the new\nfrom_user fields in struct rq_map_data but that approach makes it\ndifficult to send this patch to stable trees because st and osst\ndrivers use struct rq_map_data (they were converted to use the block\nlayer in 2.6.29 and 2.6.30).

This duality creates some\nheadaches.\n\nFirst of all, block layer and low level drivers can\u0027t really determine\nwhat rq-\u003edata_len contains while a request is executing.  It could be\nthe total request length or it coulde be anything else one of the\nlower layers is using to keep track of residual count.  This\ncomplicates things because blk_rq_bytes() and thus\n[__]blk_end_request_all() relies on rq-\u003edata_len for PC commands.\nDrivers which want to report residual count should first cache the\ntotal request length, update rq-\u003edata_len and then complete the\nrequest with the cached data length.\n\nSecondly, it makes requests default to reporting full residual count,\nie. reporting that no data transfer occurred.  The residual count is\nan exception not the norm; however, the driver should clear\nrq-\u003edata_len to zero to signify the normal cases while leaving it\nalone means no data transfer occurred at all.  This reverse default\nbehavior complicates code unnecessarily and renders block PC on some\ndrivers (ide-tape/floppy) unuseable.\n\nThis patch adds rq-\u003eresid_len which is used only for residual count.\n\nWhile at it, remove now unnecessasry blk_rq_bytes() caching in\nide_pc_intr() as rq-\u003edata_len is not changed anymore.\n\nBoaz\t: spotted missing conversion in osd\nSergei\t: spotted too early conversion to blk_rq_bytes() in ide-tape\n\n[ Impact: cleanup residual count handling, report 0 resid by default ]\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nCc: Bartlomiej Zolnierkiewicz \u003cbzolnier@gmail.com\u003e\nCc: Borislav Petkov \u003cpetkovbb@googlemail.com\u003e\nCc: Sergei Shtylyov \u003csshtylyov@ru.mvista.com\u003e\nCc: Mike Miller \u003cmike.miller@hp.com\u003e\nCc: Eric Moore \u003cEric.Moore@lsi.com\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Doug Gilbert \u003cdgilbert@interlog.com\u003e\nCc: Mike Miller \u003cmike.miller@hp.com\u003e\nCc: Eric Moore \u003cEric.Moore@lsi.com\u003e\nCc: Darrick J.

This leads to the special sg state (the orphan\nstate), then sg calls blk_put_request in interrupt (rq-\u003eend_io).\n\nThe above bug report shows the recursive lock problem because sg calls\nblk_put_request in interrupt. We could call __blk_put_request here\ninstead however we also need to handle blk_rq_unmap_user here, which\ncan\u0027t be called in interrupt too.\n\nIn the orphan state, we don\u0027t need to care about the data transfer\n(the program revoked the command) so adding \u0027just free the resource\u0027\nmode to blk_rq_unmap_user is a possible option.\n\nI prefer to avoid complicating the blk mapping API when possible. I\nchange the orphan state to call sg_finish_rem_req via\nexecute_in_process_context. We hold sg_fd-\u003ekref so sg_fd doesn\u0027t go\naway until keventd_wq finishes our work. copy_from_user/to_user fails\nso blk_rq_unmap_user just frees the resource without the data\ntransfer.\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nAcked-by: Douglas Gilbert \u003cdgilbert@interlog.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\n"

This patch fixes these problems by using krefs\nto manage the lifetime of sg_device and sg_fd.\n\nEach command submitted to the midlevel holds a reference to sg_fd\nuntil the completion callback.  This ensures that sg_fd doesn\u0027t go\naway if the fd is closed with commands still outstanding.\n\nsg_fd gets the reference of sg_device (with scsi_device) and also\nmakes sure that the sg module doesn\u0027t go away.\n\n/proc/scsi/sg/* functions don\u0027t play nicely with krefs because they\ngive information about sg_fds which have been closed but not yet\nfreed due to still having outstanding commands and sg_devices which\nhave been removed but not yet freed due to still being referenced\nby one or more sg_fds.

      "message": "block: move cmdfilter from gendisk to request_queue\n\ncmd_filter works only for the block layer SG_IO with SCSI block\ndevices. It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI\ncharacter devices (such as st). We hit a kernel crash with them.\n\nThe problem is that cmd_filter code accesses to gendisk (having struct\nblk_scsi_cmd_filter) via inode-\u003ei_bdev-\u003ebd_disk. It works for only\nSCSI block device files. With character device files, inode-\u003ei_bdev\nleads you to struct cdev. inode-\u003ei_bdev-\u003ebd_disk-\u003eblk_scsi_cmd_filter\nisn\u0027t safe.\n\nSCSI ULDs don\u0027t expose gendisk; they keep it private. bsg needs to be\nindependent on any protocols. We shouldn\u0027t change ULDs to expose their\ngendisk.\n\nThis patch moves struct blk_scsi_cmd_filter from gendisk to\nrequest_queue, a common object, which eveyone can access to.\n\nThe user interface doesn\u0027t change; users can change the filters via\n/sys/block/. gendisk has a pointer to request_queue so the cmd_filter\ncode accesses to struct blk_scsi_cmd_filter.\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"

This will effectively make it default to max_sectors.\nNote that the actual value is meaningless anyway, since block devices\ndon\u0027t have a reserved buffer.\n\nFinally, the BLKSECTGET ioctl is added to sg, so that there will be a\nuniform way for users to determine the actual max_sectors value for\nany raw SCSI transport.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nAcked-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nAcked-by: Douglas Gilbert \u003cdougg@torque.net\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@SteelEye.com\u003e\n"
