usb: storage: shuttle_usbat: fix discs being detected twice

2014-05-03T22:04:28+00:00

Even if the USB-to-ATAPI converter supported multiple LUNs, this driver would always detect the same physical device or media because it doesn't use srb->device->lun in any way. Tested with an Hewlett-Packard CD-Writer Plus 8200e. Signed-off-by: Daniele Forsi Cc: stable Signed-off-by: Greg Kroah-Hartman

uas: fix deadlocky memory allocations

2014-04-16T21:04:59+00:00

There are also two allocations with GFP_KERNEL in the pre-/post_reset code paths. That is no good because that is a part of the SCSI error handler. Signed-off-by: Oliver Neukum Reviewed-by: Hans de Goede Acked-by: Hans de Goede Signed-off-by: Greg Kroah-Hartman

uas: fix error handling during scsi_scan()

2014-04-16T21:04:59+00:00

intfdata is set only after scsi_scan(). uas_pre_reset() however needs intfdata to be valid and will follow the NULL pointer killing khubd. intfdata must be preemptively set before the host is registered and undone in the error case.

uas: fix GFP_NOIO under spinlock

Quote Dan: The patch e36e64930cff: "uas: Use GFP_NOIO rather then GFP_ATOMIC where possible" from Nov 7, 2013, leads to the following static checker warning: drivers/usb/storage/uas.c:806 uas_eh_task_mgmt() error: scheduling with locks held: 'spin_lock:lock' Some other allocations under spinlock are not caught.

storage: accept some UAS devices if streams are unavailable

2014-03-04T23:41:09+00:00

On some older XHCIs streams are not supported and the UAS driver will fail at probe time. For those devices storage should try to bind to UAS devices. This patch adds a flag for stream support to HCDs and evaluates it. [Note: Sarah fixed a bug where the USB 2.0 root hub, not USB 3.0 root hub would get marked as being able to support streams.] Signed-off-by: Oliver Neukum Signed-off-by: Sarah Sharp Acked-by: Hans de Goede

uas: Remove comment about registering a uas scsi controller for each usb bus

2014-03-04T23:38:27+00:00

Although an interesting concept, I don't think that this is a good idea: -This will result in lots of "virtual" scsi controllers confusing users -If we get a scsi-bus-reset we will now need to do a usb-device-reset of all uas devices on the same usb bus, which is something to avoid if possible Signed-off-by: Hans de Goede Signed-off-by: Sarah Sharp

uas: Add Hans de Goede as uas maintainer

2014-03-04T23:38:27+00:00

At the kernel-summit Sarah Sharp asked me if I was willing to become the uas maintainer. I said yes, and here is a patch to make this official. Also remove Matthew Wilcox and Sarah Sharp as maintainers at their request. I've also added myself to the module's author tag, so that if people look there rather then in maintainers they will know they should bug me about uas too.
