2015-07-23usb: usleep_range is preferred over udelay where wakeup is flexibleSunny Kumar1-1/+1
According to Documentation/timers/timers-howto.txt" udelay() is only called once from a place where sleeping is allowed. We can replace it with a call to usleep_range() with a reasonable upper limit.

2015-07-23usb-storage: Add ignore-device quirk for gm12u320 based usb mini projectorsHans de Goede1-0/+11
Grain-media GM12U320 based devices are mini video projectors using USB for both power and video data transport. Their usb-storage interface is a virtual windows driver CD. The gm12u320 kms driver needs these interfaces to talk to the device and export it as framebuffer & kms dri device nodes, so make sure that the usb-storage driver does not bind to it.

2015-07-23usb-storage: ignore ZTE MF 823 card reader in mode 0x1225Oliver Neukum1-0/+12
This device automatically switches itself to another mode (0x1405) unless the specific access pattern of Windows is followed in its initial mode. That makes a dirty unmount of the internal storage devices inevitable if they are mounted. So the card reader of such a device should be ignored, lest an unclean removal become inevitable. This replaces an earlier patch that ignored all LUNs of this device. That patch was overly broad.

2015-05-10usb: storage: fix module reference for scsi hostAkinobu Mita17-47/+150
While accessing a unusual usb storage (ums-alauda, ums-cypress, ...), the module reference count is not incremented. Because these drivers allocate scsi hosts with usb_stor_host_template defined in usb-storage module. So these drivers always can be unloaded. This fixes it by preparing scsi host template which is initialized at module_init() for each ums-* driver. In order to minimize the difference in ums-* drivers, introduce module_usb_stor_driver() helper macro which is same as module_usb_driver() except that it also initializes scsi host template.

2015-01-09uas: Do not blacklist ASM1153 disk enclosuresHans de Goede2-13/+28
Our detection logic to avoid doing UAS on ASM1051 bridge chips causes problems with newer ASM1153 disk enclosures in 2 ways: 1) Some ASM1153 disk enclosures re-use the ASM1051 device-id of 5106, which we assume is always an ASM1051, so remove the quirk for 5106, and instead use the same detection logic as we already use for device-id 55aa, which is used for all of ASM1051, ASM1053 and ASM1153 devices <sigh>. 2) Our detection logic to differentiate between ASM1051 and ASM1053 sees ASM1153 devices as ASM1051 because they have 32 streams like ASM1051 devs. Luckily the ASM1153 descriptors are not 100% identical, unlike the previous models the ASM1153 has bMaxPower == 0, so use that to differentiate it.

2014-11-25storage: Fix bus scan and multi-LUN support for SCM eUSCSI devicesMark Knibbs1-12/+24
This patch does two things for SCM eUSCSI USB-SCSI converters: 1. SCM eUSCSI bridge devices are hard-wired to use SCSI ID 7. On connecting the converter, access to that ID is attempted during the bus scan. Asking the converter to issue INQUIRY commands to itself isn't very polite and wastes time. Set this_id to 7 so __scsi_scan_target() skips it in the scan. 2. Enable multi-LUN support. eUSCSI devices don't support Get Max LUN requests, returning an error (-32). [Different targets could have different numbers of LUNs, so it wouldn't make sense to return a particular value in response to Get Max LUN.] usb_stor_scan_dwork() does this: /* For bulk-only devices, determine the max LUN value */ if (us->protocol == USB_PR_BULK && !(us->fflags & US_FL_SINGLE_LUN)) { mutex_lock(&us->dev_mutex); us->max_lun = usb_stor_Bulk_max_lun(us); mutex_unlock(&us->dev_mutex); It avoids calling usb_stor_Bulk_max_lun() if US_FL_SINGLE_LUN, but not for US_FL_SCM_MULT_TARG. Since usb_stor_Bulk_max_lun() returns 0 in the error case, us->max_lun was always set to 0.

2014-11-25storage: Enable multi-target mode as vendor driver does for SCM eUSCSI bridgeMark Knibbs1-2/+1
usb_stor_euscsi_init() enables multi-target mode for SCM eUSB SCSI bridge devices. The control message it sends has wLength = 1 and the byte sent is 0x01. While that works, the SCM Windows driver does it with wLength = 0. We may as well match what the SCM driver does.

2014-11-12scsi: don't set tagging state from scsi_adjust_queue_depthChristoph Hellwig1-1/+1
Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.

2014-11-12scsi: always assign block layer tags if enabledChristoph Hellwig1-2/+2
Allow a driver to ask for block layer tags by setting .use_blk_tags in the host template, in which case it will always see a valid value in request->tag, similar to the behavior when using blk-mq. This means even SCSI "untagged" commands will now have a tag, which is especially useful when using a host-wide tag map.

2014-11-12scsi: add new scsi-command flag for tagged commandsChristoph Hellwig1-1/+1
Currently scsi piggy backs on the block layer to define the concept of a tagged command. But we want to be able to have block-level host-wide tags assigned even for untagged commands like the initial INQUIRY, so add a new SCSI-level flag for commands that are tagged at the scsi level, so that even commands without that set can have tags assigned to them. Note that this alredy is the case for the blk-mq code path, and this just lets the old path catch up with it. We also set this flag based upon sdev->simple_tags instead of the block queue flag, so that it is entirely independent of the block layer tagging, and thus always correct even if a driver doesn't use block level tagging yet. Also remove the old blk_rq_tagged; it was only used by SCSI drivers, and removing it forces them to look for the proper replacement.

2014-11-07USB: storage: Reject bogus max LUN valuesMark Knibbs1-3/+14
Some mass storage devices return a bogus value in response to a Get Max LUN request. The Iomega Jaz USB Adapter responds with 0x10, hence my recent patch to use the US_FL_SINGLE_LUN quirk for it. The USB MSC Bulk Only Transport document says "The device shall return one byte of data that contains the maximum LUN supported by the device." Since the LUN field in the command block wrapper is only 4 bits wide, it might be helpful to report too-large LUN values in the kernel log, and assume max LUN is actually 0. That could get some devices which currently need the US_FL_SINGLE_LUN quirk to work.
