USB: UAS: use macro for reporting results

2020-09-16T10:43:35+00:00

The SCSI layer has introduced a new macro for recording the result of a command. Use it. Signed-off-by: Oliver Neukum Link: https://lore.kernel.org/r/20200916094026.30085-3-oneukum@suse.com Signed-off-by: Greg Kroah-Hartman

USB: UAS: fix disconnect by unplugging a hub

2020-09-16T10:43:24+00:00

The SCSI layer can go into an ugly loop if you ignore that a device is gone. You need to report an error in the command rather than in the return value of the queue method. We need to specifically check for ENODEV. The issue goes back to the introduction of the driver.

uas: bump hw_max_sectors to 2048 blocks for SS or faster drives

2020-09-04T15:00:39+00:00

There's no reason for uas to use a smaller value of max_sectors than usb-storage. Signed-off-by: Tom Yan Reviewed-by: Alan Stern Link: https://lore.kernel.org/r/20200903181725.2931-3-tom.ty89@gmail.com Signed-off-by: Greg Kroah-Hartman

uas: fix sdev->host->dma_dev

2020-09-04T15:00:39+00:00

Use scsi_add_host_with_dma() instead of scsi_add_host(). When the scsi request queue is initialized/allocated, hw_max_sectors is clamped to the dma max mapping size. Therefore, the correct device that should be used for the clamping needs to be set. The same clamping is still needed in uas as hw_max_sectors could be changed there. The original clamping would be invalidated in such cases.

Pull USB fixes from Greg KH: "Let's try this again... Here are some USB fixes for 5.9-rc3. This differs from the previous pull request for this release in that the usb gadget patch now does not break some systems, and actually does what it was intended to do. Many thanks to Marek Szyprowski for quickly noticing and testing the patch from Andy Shevchenko to resolve this issue. Additionally, some more new USB quirks have been added to get some new devices to work properly based on user reports. Other than that, the patches are all here, and they contain: - usb gadget driver fixes - xhci driver fixes - typec fixes - new quirks and ids - fixes for USB patches that went into 5.9-rc1.

usb: storage: Add unusual_uas entry for Sony PSZ drives

2020-08-28T07:23:16+00:00

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

2020-08-27T07:26:00+00:00

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.
