USB: storage: add quirk for SMI SM3350

2019-01-16T21:16:10+00:00

commit 0a99cc4b8ee83885ab9f097a3737d1ab28455ac0 upstream. The SMI SM3350 USB-UFS bridge controller cannot handle long sense request correctly and will make the chip refuse to do read/write when requested long sense. Add a bad sense quirk for it.

USB: storage: don't insert sane sense for SPC3+ when bad sense specified

2019-01-16T21:16:10+00:00

commit c5603d2fdb424849360fe7e3f8c1befc97571b8c upstream. Currently the code will set US_FL_SANE_SENSE flag unconditionally if device claims SPC3+, however we should allow US_FL_BAD_SENSE flag to prevent this behavior, because SMI SM3350 UFS-USB bridge controller, which claims SPC4, will show strange behavior with 96-byte sense (put the chip into a wrong state that cannot read/write anything). Check the presence of US_FL_BAD_SENSE when assuming US_FL_SANE_SENSE on SPC4+ devices. Signed-off-by: Icenowy Zheng Cc: stable Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

usb-storage: fix bogus hardware error messages for ATA pass-thru devices

2018-11-10T15:41:37+00:00

[ Upstream commit a4fd4a724d6c30ad671046d83be2e9be2f11d275 ] Ever since commit a621bac3044e ("scsi_lib: correctly retry failed zero length REQ_TYPE_FS commands"), people have been getting bogus error messages for USB disk drives using ATA pass-thru. For example: [ 1344.880193] sd 6:0:0:0: [sdb] Attached SCSI disk [ 1345.069152] sd 6:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_SENSE [ 1345.069159] sd 6:0:0:0: [sdb] tag#0 Sense Key : Hardware Error [current] [descriptor] [ 1345.069162] sd 6:0:0:0: [sdb] tag#0 Add.

Other programs can also have this effect, such as those in smartmontools. I don't fully understand how that commit induced the SCSI core to log these error messages, but the underlying cause for them is code added to usb-storage by commit f1a0743bc0e7 ("USB: storage: When a device returns no sense data, call it a Hardware Error"). At the time it was necessary to do this, in order to prevent an infinite retry loop with some not-so-great mass storage devices. However, the ATA pass-thru protocol uses SCSI sense data to return command status values, and some devices always report Check Condition status for ATA pass-thru commands to ensure that the host retrieves the sense data, even if the command succeeded. This violates the USB mass-storage protocol (Check Condition status is supposed to mean the command failed), but we can't help that. This patch attempts to mitigate the problem of these bogus error reports by changing usb-storage. The HARDWARE ERROR sense key will be inserted only for commands that aren't ATA pass-thru. Thanks to Ewan Milne for pointing out that this mechanism was present in usb-storage. 8 years after writing it, I had completely forgotten its existence.

USB: Add quirk to support DJI CineSSD

2018-09-26T06:35:07+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: ene_usb6250: fix SCSI residue overwriting

2018-04-13T17:50:07+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

2018-04-13T17:50:07+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

2018-02-03T16:04:30+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.
