USB: uas: Add no-uas quirk for Hitachi usb-3 enclosures 4971:1012

2014-12-06T23:57:25+00:00

commit 8daee1352d51a32676b84bddcc0e3252d1caa833 upstream.

These disks have a broken uas implementation, the tag field of the status
iu-s is not set properly, so we need to fall-back to usb-storage for these.

usb-storage: handle a skipped data phase

2014-11-14T18:10:35+00:00

commit 93c9bf4d1838d5851a18ca398b0ad66397f05056 upstream.

Sometimes mass-storage devices using the Bulk-only transport will
mistakenly skip the data phase of a command.  Rather than sending the
data expected by the host or sending a zero-length packet, they go
directly to the status phase and send the CSW.

This causes problems for usb-storage, for obvious reasons.  The driver
will interpret the CSW as a short data transfer and will wait to
receive a CSW.  The device won't have anything left to send, so the
command eventually times out.

The SCSI layer doesn't retry commands after they time out (this is a
relatively recent change).  Therefore we should do our best to detect
a skipped data phase and handle it promptly.

This patch adds code to do that.  If usb-storage receives a short
13-byte data transfer from the device, and if the first four bytes of
the data match the CSW signature, the driver will set the residue to
the full transfer length and interpret the data as a CSW.

This fixes Bugzilla #86611.

uas: Add US_FL_NO_ATA_1X quirk for 1 more Seagate model

2014-11-14T18:10:34+00:00

commit aee0ce3ae73c566ace9958302e001d3cbbb0a623 upstream.

These drives hang when receiving ATA12 commands, so set the US_FL_NO_ATA_1X
quirk to filter these out.

commit 673029fe9c16c95600bdaca4760673527af32edf upstream.

Just like some Seagate enclosures, these devices do not seem to grok ata
pass through commands.

uas: Add another ASM1051 usb-id to the uas blacklist

2014-10-15T10:29:24+00:00

commit 710f1bf16ab1b1558f099b62c5011c4cbba6a7bb upstream.

As most ASM1051 based devices, this one has unfixable issues with uas too.

uas: Add no-report-opcodes quirk

2014-10-15T10:29:24+00:00

commit 734016b00b50a3c6a0e1fc1b7b217e783f5123a1 upstream.

Besides the ASM1051 (*) needing sdev->no_report_opcodes = 1, it turns out that
the JMicron JMS567 also needs it to work properly with uas (usb-storage always
sets it). Since some of the scsi devs were not to keen on the idea to
outrightly set sdev->no_report_opcodes = 1 for all uas devices, so add a quirk
for this, and set it for the JMS567.

*) Which has become a non-issue since we've completely blacklisted uas on
the ASM1051 for other reasons

uas: Add a quirk for rejecting ATA_12 and ATA_16 commands

2014-10-15T10:29:23+00:00

commit 593078525c8b234a35a36ff551b8716464e86481 upstream.

And set this quirk for the Seagate Expansion Desk (0bc2:2312), as that one
seems to hang upon receiving an ATA_12 or ATA_16 command.

While at it also add missing documentation for the u value for usb-storage
