2014-11-24storage: Fix bus scan and multi-LUN support for SCM eUSCSI devicesMark Knibbs
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. [If the user doesn't want multi-LUN support (perhaps there are SCSI devices which respond to commands on all LUNs?), the US_FL_SINGLE_LUN quirk can be specified on the kernel command line.] Signed-off-by: Mark Knibbs <markk@clara.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-11-24storage: Enable multi-target mode as vendor driver does for SCM eUSCSI bridgeMark Knibbs
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.

The bulkstat fixes are large but necessary. I wouldn't normally push such a rework for a -rcX update, but right now xfsdump can silently create incomplete dumps on 3.17 and it's possible that even xfsrestore won't notice that the dumps were incomplete. Hence we need to get this update into 3.17-stable kernels ASAP. In more detail, the refactoring work I committed in 3.17 has exposed a major hole in our QA coverage. With both xfsdump (the major user of bulkstat) and xfsrestore silently ignoring missing files in the dump/restore process, incomplete dumps were going unnoticed if they were being triggered. Many of the dump/restore filesets were so small that they didn't evenhave a chance of triggering the loop iteration bugs we introduced in 3.17, so we didn't exercise the code sufficiently, either. We have already taken steps to improve QA coverage in xfstests to avoid this happening again, and I've done a lot of manual verification of dump/restore on very large data sets (tens of millions of inodes) of the past week to verify this patch set results in bulkstat behaving the same way as it does on 3.16. Unfortunately, the fixes are not exactly simple - in tracking down the problem historic API warts were discovered (e.g xfsdump has been working around a 20 year old bug in the bulkstat API for the past 10 years) and so that complicated the process of diagnosing and fixing the problems. i.e. we had to fix bugs in the code as well as discover and re-introduce the userspace visible API bugs that we unwittingly "fixed" in 3.17 that xfsdump relied on to work correctly.

2014-11-07fotg210: Make Xen notification consistent with EHCIChris Rorvick
If CONFIG_XEN_DOM0 is enabled, the ehci-dbgp driver notifies Xen of controller reset events via xen_dbgp_reset_prep() and xen_dbgp_external_startup() (via calls to xen_dbgp_op().) Otherwise <linux/usb/ehci_def.h> defines them as no-ops to disable this logic. The fotg210 driver copies much of the dbgp code from ehci_def.h, but it unconditionally defines the Xen hooks as no-ops, effectively disabling these notifications when CONFIG_EARLY_PRINTK_DBGP is disabled. When enabled, though, notifying Xen is dependent on CONFIG_XEN_DOM0 due to fotg210 leveraging the ehci-dbgp driver. The following table compares the implementations of xen_dbgp_reset_prep() and xen_dbgp_external_startup() in the ehci-dbgp and fotg210 drivers under the relevant configurations: EARLY_PRINTK_DBGP?
