usb: storage: Add unusual_uas entry for Sony PSZ drives

2020-09-03T09:19:28+00:00

commit 20934c0de13b49a072fb1e0ca79fe0fe0e40eae5 upstream. The PSZ-HA* family of USB disk drives from Sony can't handle the REPORT OPCODES command when using the UAS protocol. This patch adds an appropriate quirks entry.

USB: Ignore UAS for JMicron JMS567 ATA/ATAPI Bridge

2020-09-03T09:19:27+00:00

commit 9aa37788e7ebb3f489fb4b71ce07adadd444264a upstream. This device does not support UAS properly and a similar entry already exists in drivers/usb/storage/unusual_uas.h. Without this patch, storage_probe() defers the handling of this device to UAS, which cannot handle it either.

usb: uas: Add quirk for PNY Pro Elite

2020-09-03T09:19:27+00:00

commit 9a469bc9f32dd33c7aac5744669d21a023a719cd upstream. PNY Pro Elite USB 3.1 Gen 2 device (SSD) doesn't respond to ATA_12 pass-through command (i.e. it just hangs). If it doesn't support this command, it should respond properly to the host. Let's just add a quirk to be able to move forward with other operations.

USB: uas: add quirk for LaCie 2Big Quadra

commit 9f04db234af691007bb785342a06abab5fb34474 upstream. This device needs US_FL_NO_REPORT_OPCODES to avoid going through prolonged error handling on enumeration.

UAS: fix deadlock in error handling and PM flushing work

2020-05-02T15:20:50+00:00

commit f6cc6093a729ede1ff5658b493237c42b82ba107 upstream. A SCSI error handler and block runtime PM must not allocate memory with GFP_KERNEL. Furthermore they must not wait for tasks allocating memory with GFP_KERNEL. That means that they cannot share a workqueue with arbitrary tasks. Fix this for UAS using a private workqueue.

UAS: no use logging any details in case of ENODEV

commit 5963dec98dc52d52476390485f07a29c30c6a582 upstream. Once a device is gone, the internal state does not matter anymore. There is no need to spam the logs.

usb-storage: Add unusual_devs entry for JMicron JMS566

2020-05-02T15:20:48+00:00

commit 94f9c8c3c404ee1f7aaff81ad4f24aec4e34a78b upstream. Cyril Roelandt reports that his JMicron JMS566 USB-SATA bridge fails to handle WRITE commands with the FUA bit set, even though it claims to support FUA. (Oddly enough, a later version of the same bridge, version 2.03 as opposed to 1.14, doesn't claim to support FUA. Also oddly, the bridge _does_ support FUA when using the UAS transport instead of the Bulk-Only transport -- but this device was blacklisted for uas in commit bc3bdb12bbb3 ("usb-storage: Disable UAS on JMicron SATA enclosure") for apparently unrelated reasons.) This patch adds a usb-storage unusual_devs entry with the BROKEN_FUA flag. This allows the bridge to work properly with usb-storage.

usb: storage: Add quirk for Samsung Fit flash

2020-03-11T06:51:17+00:00

commit 86d92f5465958752481269348d474414dccb1552 upstream. Current driver has 240 (USB2.0) and 2048 (USB3.0) as max_sectors, e.g., /sys/bus/scsi/devices/0:0:0:0/max_sectors If data access times out, driver error handling will issue a port reset. Sometimes Samsung Fit (090C:1000) flash disk will not respond to later Set Address or Get Descriptor command. Adding this quirk to limit max_sectors to 64 sectors to avoid issue occurring.

usb: uas: fix a plug & unplug racing

2020-02-28T14:39:12+00:00

commit 3e99862c05a9caa5a27969f41566b428696f5a9a upstream. When a uas disk is plugged into an external hub, uas_probe() will be called by the hub thread to do the probe. It will first create a SCSI host and then do the scan for this host. During the scan, it will probe the LUN using SCSI INQUERY command which will be packed in the URB and submitted to uas disk. There might be a chance that this external hub with uas disk attached is unplugged during the scan. In this case, uas driver will fail to submit the URB (due to the NOTATTACHED state of uas device) and try to put this SCSI command back to request queue waiting for next chance to run. In normal case, this cycle will terminate when hub thread gets disconnection event and calls into uas_disconnect() accordingly. But in this case, uas_disconnect() will not be called because hub thread of external hub gets stuck waiting for the completion of this SCSI command. A deadlock happened. In this fix, uas will call scsi_scan_host() asynchronously to avoid the blocking of hub thread.
