usb: uas: add support for more quirk flags

2018-09-26T06:36:35+00:00

commit 42d1c6d4a06a77b3ab206a919b9050c3080f3a71 upstream.

The hope that UAS devices would be less broken than old style storage
devices has turned out to be unfounded. Make UAS support more of the
quirk flags of the old driver.

USB: Add quirk to support DJI CineSSD

2018-09-26T06:36:35+00:00

commit f45681f9becaa65111ed0a691ccf080a0cd5feb8 upstream.

This device does not correctly handle the LPM operations.

Also, the device cannot handle ATA pass-through commands
and locks up when attempted while running in super speed.

This patch adds the equivalent quirk logic as found in uas.

usb-storage: Add compatibility quirk flags for G-Technologies G-Drive

2018-06-16T07:52:33+00:00

commit ca7d9515d0e6825351ce106066cea1f60e40b1c8 upstream.

The "G-Drive" (sold by G-Technology) external USB 3.0 drive
 hangs on write access under UAS and usb-storage:

The proposed patch adds compatibility quirks. Because the drive requires two
quirks (one to work with UAS, and another to work with usb-storage), adding this
under unusual_devs.h and not just unusual_uas.h so kernels compiled without UAS
receive the quirk. With the patch, the drive works reliably on UAS and usb-
storage.
(tested on NEC Corporation uPD720200 USB 3.0 host controller).

usb-storage: Add support for FL_ALWAYS_SYNC flag in the UAS driver

2018-06-16T07:52:33+00:00

commit 8c4e97ddfe73a0958bb0abf7e6a3bc4cc3e04936 upstream.

The ALWAYS_SYNC flag is currently honored by the usb-storage driver but not UAS
and is required to work around devices that become unstable upon being
queried for cache. This code is taken straight from:
drivers/usb/storage/scsiglue.c:284

USB: ene_usb6250: fix SCSI residue overwriting

2018-04-13T17:48:00+00:00

[ Upstream commit aa18c4b6e0e39bfb00af48734ec24bc189ac9909 ]

In the ene_usb6250 sub-driver for usb-storage, the SCSI residue is not
reported correctly.  The residue is initialized to 0, but this value
is overwritten whenever the driver sends firmware to the card reader
before performing the current command.  As a result, a valid READ or
WRITE operation appears to have failed, causing the SCSI core to retry
the command multiple times and eventually fail.

This patch fixes the problem by resetting the SCSI residue to 0 after
sending firmware to the device.

USB: ene_usb6250: fix first command execution

2018-04-13T17:48:00+00:00

[ Upstream commit 4b309f1c4972c8f09e03ac64fc63510dbf5591a4 ]

In the ene_usb6250 sub-driver for usb-storage, the ene_transport()
routine is supposed to initialize the driver before executing the
current command, if the initialization has not already been performed.
However, a bug in the routine causes it to skip the command after
doing the initialization.  Also, the routine does not return an
appropriate error code if either the initialization or the command
fails.

As a result of the first bug, the first command (a SCSI INQUIRY) is
not carried out.  The results can be seen in the system log, in the
form of a warning message and empty or garbage INQUIRY data:

Apr 18 22:40:08 notebook2 kernel: scsi host6: scsi scan: INQUIRY result too short (5), using 36
Apr 18 22:40:08 notebook2 kernel: scsi 6:0:0:0: Direct-Access                                    PQ: 0 ANSI: 0

This patch fixes both errors.

usb: uas: unconditionally bring back host after reset

2018-02-03T16:05:42+00:00

commit cbeef22fd611c4f47c494b821b2b105b8af970bb upstream.

Quoting Hans:

If we return 1 from our post_reset handler, then our disconnect handler
will be called immediately afterwards. Since pre_reset blocks all scsi
requests our disconnect handler will then hang in the scsi_remove_host
call.

This is esp. bad because our disconnect handler hanging for ever also
stops the USB subsys from enumerating any new USB devices, causes commands
like lsusb to hang, etc.

In practice this happens when unplugging some uas devices because the hub
code may see the device as needing a warm-reset and calls usb_reset_device
before seeing the disconnect. In this case uas_configure_endpoints fails
with -ENODEV. We do not want to print an error for this, so this commit
also silences the shost_printk for -ENODEV.

ENDQUOTE

However, if we do that we better drop any unconditional execution
and report to the SCSI subsystem that we have undergone a reset
but we are not operational now.

uas: ignore UAS for Norelsys NS1068(X) chips

2018-01-17T08:38:56+00:00

commit 928afc85270753657b5543e052cc270c279a3fe9 upstream.

The UAS mode of Norelsys NS1068(X) is reported to fail to work on
several platforms with the following error message:

xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8
xhci-hcd xhci-hcd.0.auto: @00000000bf04a400 00000000 00000000 1b000000 01098001

And when trying to mount a partition on the disk the disk will
disconnect from the USB controller, then after re-connecting the device
will be offlined and not working at all.

Falling back to USB mass storage can solve this problem, so ignore UAS
function of this chip.
