I\u0027m crazy enough to try to make them work. So this time a\nfriend of mine asked me to get an mp4 player (an mp3 player which can play\nvideos on a small screen) to work with Linux.\n\nIt is based on the well known rockbox chipset for which we already have an\nunusual devs entries to work around some of its bugs. But this model\ncomes with an additional twist.\n\nThis model chokes on read_capacity_16 calls. Now normally we don\u0027t make\nthose calls, but this model comes with an sdcard slot and when there is no\ncard in there (and shipped from the factory there is none), it reports a\nsize of 0. However this time the programmers actually got the\nread_capacity_10 response right! So they substract one from the size as\nstored internally in the mp3 player before reporting it back, resulting in\nan answer of ... 0xffffffff sectors, causing sd.c to try a\nread_capacity_16, on which the device crashes.\n\nThis patch adds a flag to scsi_device to indicate that a a device cannot\nhandle read_capacity_16, and when this flag is set if a device reports an\nlba of 0xffffffff as answer to a read_capacity_10, assumes it tries to\nreport a size of 0.\n\nSigned-off-by: Hans de Goede \u003chdegoede@redhat.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: Matthew Dharm \u003cmdharm-usb@one-eyed-alien.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "8e04d8056c1ea0e0aab730994b74756f0526cda8", "tree": "b81a3e2f5993c69559d120fa96840e1ef70b42d4", "parents": [ "319feaabb6c7ccd90da6e3207563c265da7d21ae" ], "author": { "name": "Hans de Goede", "email": "hdegoede@redhat.com", "time": "Fri Oct 01 14:20:08 2010 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Oct 22 10:22:04 2010 -0700" }, "message": "scsi/sr: add no_read_disc_info scsi_device flag\n\nSome USB devices emulate a usb-mass-storage attached (scsi) cdrom device,\nusually this fake cdrom contains the windows software for the device.\nWhile working on supporting Appotech ax3003 based photoframes, which do\nthis I discovered that they will go of into lala land when ever they see a\nREAD_DISC_INFO scsi command.\n\nThus this patch adds a scsi_device flag (which can then be set by the\nusb-storage driver through an unsual-devs entry), to indicate this, and\nmakes the sr driver honor this flag.\n\nI know this sucks, but as discussed on linux-scsi list there is no other\nway to make this device work properly.\n\nLooking at usb traces made under windows, windows never sends a\nREAD_DISC_INFO during normal interactions with a usb cdrom device.

Only\nthe machanism is provided; use of it is up to the various high-level\ndrivers, and the patch doesn\u0027t change any of them. Except for sg --\nthe patch expicitly prevents a device from being runtime-suspended\nwhile its sg device file is open.\n\nThe implementation is simplistic. In general, hosts and targets are\nautomatically suspended when all their children are asleep, but for\nthem the runtime-suspend code doesn\u0027t actually do anything. (A host\u0027s\nruntime PM status is propagated up the device tree, though, so a\nruntime-PM-aware lower-level driver could power down the host adapter\nhardware at the appropriate times.) There are comments indicating\nwhere a transport class might be notified or some other hooks added.\n\nLUNs are runtime-suspended by calling the drivers\u0027 existing suspend\nhandlers (and likewise for runtime-resume). Somewhat arbitrarily, the\nimplementation delays for 100 ms before suspending an eligible LUN.\nThis is because there typically are occasions during bootup when the\nsame device file is opened and closed several times in quick\nsuccession.\n\nThe way this all works is that the SCSI core increments a device\u0027s\nPM-usage count when it is registered. If a high-level driver does\nnothing then the device will not be eligible for runtime-suspend\nbecause of the elevated usage count. If a high-level driver wants to\nuse runtime PM then it can call scsi_autopm_put_device() in its probe\nroutine to decrement the usage count and scsi_autopm_get_device() in\nits remove routine to restore the original count.\n\nHosts, targets, and LUNs are not suspended while they are being probed\nor removed, or while the error handler is running. In fact, a fairly\nlarge part of the patch consists of code to make sure that things\naren\u0027t suspended at such times.\n\n[jejb: fix up compile issues in PM config variations]\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "df64d3caab8db6ae17dacd229a03d7689a10c432", "tree": "247fe4f9f39b22186e42e7f4687dd62c2690e47b", "parents": [ "653c42d552d0fd0b05485442aed45dd2d62269c0" ], "author": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Tue Jul 27 15:51:13 2010 -0500" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Jul 28 09:07:49 2010 -0500" }, "message": "[SCSI] Unify SAM_ and SAM_STAT_ macros\n\nWe have two separate definitions for identical constants with nearly the\nsame name.

This is handled by not resetting rdata-\u003eevent\nton NONE if the rdata is about to be deleted.\n\nHowever, that fix led to the second problem, described by\nBhanu Gollapudi, as follows:\n\u003e Here is the sequence of events. T1 is first LOGO receive thread, T2 is\n\u003e fc_rport_work() scheduled by T1 and T3 is second LOGO receive thread and\n\u003e T4 is fc_rport_work scheduled by T3.\n\u003e\n\u003e 1. (T1)Received 1st LOGO in state Ready\n\u003e 2. (T1)Delete port \u0026 enter to RESTART state.\n\u003e 3. (T1)schdule event_work, since event is RPORT_EV_NONE.\n\u003e 4. (T1)set event \u003d RPORT_EV_LOGO\n\u003e 5. (T1)Enter RESTART state as disc_id is set.\n\u003e 6. (T2)remember to PLOGI, and set event \u003d RPORT_EV_NONE\n\u003e 6. (T3)Received 2nd LOGO\n\u003e 7. (T3)Delete Port \u0026 enter to RESTART state.\n\u003e 8. (T3)schedule event_work, since event is RPORT_EV_NONE.\n\u003e 9. (T3)Enter RESTART state as disc_id is set.\n\u003e 9. (T3)set event \u003d RPORT_EV_LOGO\n\u003e 10.(T2)work restart, enter PLOGI state and issues PLOGI\n\u003e 11.(T4)Since state is not RESTART anymore, restart is not set, and the\n\u003e event is not reset to RPORT_EV_NONE. (current event is RPORT_EV_LOGO).\n\u003e 12. Now, PLOGI succeeds and fc_rport_enter_ready() will not schedule\n\u003e event_work, and hence the rport will never be created, eventually losing\n\u003e the target after dev_loss_tmo.\n\nSo, the problem here is that we were tracking the desire for\nthe rport be restarted by state RESTART, which was otherwise\nequivalent to DELETE. A contributing factor is that we dropped\nthe lock between steps 6 and 10 in thread T2, which allows the\nstate to change, and we didn\u0027t completely re-evaluate then.\n\nThis is hopefully corrected by the following minor redesign:\n\nSimplify the rport restart logic by making the decision to\nrestart after deleting the transport rport. That decision\nis based on a new STARTED flag that indicates fc_rport_login()\nhas been called and fc_rport_logoff() has not been called\nsince then.

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": "961cde93dee2658000ead32abffb8ddf0727abe0", "tree": "2419e204132abe2ec2bb7f08bd20042573cc9bd6", "parents": [ "f82c37e7bb4c4d9b6a476c642d5c2d2efbd6f240", "0d9dc7c8b9b7fa0f53647423b41056ee1beed735" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 18 16:54:31 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 18 16:54:31 2010 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (69 commits)\n [SCSI] scsi_transport_fc: Fix synchronization issue while deleting vport\n [SCSI] bfa: Update the driver version to 2.1.2.1.\n [SCSI] bfa: Remove unused header files and did some cleanup.\n [SCSI] bfa: Handle SCSI IO underrun case.\n [SCSI] bfa: FCS and include file changes.\n [SCSI] bfa: Modified the portstats get/clear logic\n [SCSI] bfa: Replace bfa_get_attr() with specific APIs\n [SCSI] bfa: New portlog entries for events (FIP/FLOGI/FDISC/LOGO).\n [SCSI] bfa: Rename pport to fcport in BFA FCS.\n [SCSI] bfa: IOC fixes, check for IOC down condition.\n [SCSI] bfa: In MSIX mode, ignore spurious RME interrupts when FCoE ports are in FW mismatch state.\n [SCSI] bfa: Fix Command Queue (CPE) full condition check and ack CPE interrupt.\n [SCSI] bfa: IOC recovery fix in fcmode.\n [SCSI] bfa: AEN and byte alignment fixes.\n [SCSI] bfa: Introduce a link notification state machine.\n [SCSI] bfa: Added firmware save clear feature for BFA driver.\n [SCSI] bfa: FCS authentication related changes.\n [SCSI] bfa: PCI VPD, FIP and include file changes.\n [SCSI] bfa: Fix to copy fpma MAC when requested by user space application.\n [SCSI] bfa: RPORT state machine: direct attach mode fix.\n ...\n" }, { "commit": "15485a4682d1d3bfee2aa78b4b1a5d36f5746b64", "tree": "538857520760de1cf3575c8b5e4f73bab70557ff", "parents": [ "5ed109103d73b0bafc92e860cead56725231384d" ], "author": { "name": "Dave Young", "email": "hidave.darkstar@gmail.com", "time": "Wed Mar 10 15:24:07 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 12 15:53:10 2010 -0800" }, "message": "sysctl extern cleanup: sg\n\nExtern declarations in sysctl.c should be moved to their own header file,\nand then include them in relavant .c files.\n\nMove sg_big_buff extern declaration to scsi/sg.h\n\nSigned-off-by: Dave Young \u003chidave.darkstar@gmail.com\u003e\nAcked-by: Doug Gilbert \u003cdgilbert@interlog.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "309ce156aa27f29338438011d292a8d6496623d3", "tree": "7d0554a3a6c7c15b612b8eeb00991c0e54cdaf1e", "parents": [ "d7b4627f5f3390a2f350f16c047b3fc3eccce6d8" ], "author": { "name": "Jayamohan Kallickal", "email": "jayamohank@serverengines.com", "time": "Sat Feb 20 08:02:10 2010 +0530" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Mar 03 17:39:04 2010 +0530" }, "message": "[SCSI] libiscsi: Make iscsi_eh_target_reset start with session reset\n\nThe iscsi_eh_target_reset has been modified to attempt\ntarget reset only.
