Syzbot got KMSAN to complain about access to an uninitialized value in
the alauda subdriver of usb-storage:
BUG: KMSAN: uninit-value in alauda_transport+0x462/0x57f0

CPU: 0 PID: 12279 Comm: usb-storage Not tainted 5.3.0-rc7+ #0

alauda_check_media+0x344/0x3310 drivers/usb/storage/alauda.c:460
The problem is that alauda_check_media() doesn't verify that its USB
transfer succeeded before trying to use the received data. What
should happen if the transfer fails isn't entirely clear, but a
reasonably conservative approach is to pretend that no media is
present.
A similar problem exists in a usb_stor_dbg() call in
alauda_get_media_status(). In this case, when an error occurs the
call is redundant, because usb_stor_ctrl_transfer() already will print
a debugging message.
Finally, unrelated to the uninitialized memory access, is the fact
that alauda_check_media() performs DMA to a buffer on the stack.
Fortunately usb-storage provides a general purpose DMA-able buffer for
uses like this. We'll use it instead.

With faulty usb-storage devices, read/write can timeout, in that case
the SCSI layer will abort and re-issue the command. USB storage has no
internal timeout, it relies on SCSI layer aborting commands via
.eh_abort_handler() for non those responsive devices.
After two consecutive timeouts of the same command, SCSI layer calls
.eh_device_reset_handler(), without calling .eh_abort_handler() first.
With usb-storage, this causes a deadlock:
-> .eh_device_reset_handler
-> device_reset
-> mutex_lock(&(us->dev_mutex));
mutex already by usb_stor_control_thread(), which is waiting for
command completion:
-> usb_stor_control_thread (mutex taken here)
-> usb_stor_invoke_transport
-> usb_stor_Bulk_transport
-> usb_stor_bulk_srb
-> usb_stor_bulk_transfer_sglist
-> usb_sg_wait
Make sure we cancel any pending command in .eh_device_reset_handler()
to avoid this.

The commit e00b488e81 ("usb-storage: Add Hiksemi USB3-FW to IGNORE_UAS")
blacklists UAS for all of RTL9210 enclosures.
The RTL9210 controller was advertised with UAS since its release back in
2019 and was shipped with a lot of enclosure products with different
firmware combinations.
Blacklist UAS only for HIKSEMI MD202.
This should hopefully be replaced with more robust method than just
comparing strings. But with limited information [1] provided thus far
(dmesg when the device is plugged in, which includes manufacturer and
product, but no lsusb -v to compare against), this is the best we can do
for now.

Nothing major in here, lots of little things with new devices supported

and some new ids to enable new hardware devices
- USB gadget uvc updates for newer video formats and better v4l
integration (the v4l portions were acked by those maintainers)
- typec updates for tiny issues and more typec drivers for new
chips.
- xhci tiny updates for minor issues
- big usb-serial ftdi_sio driver update to handle new devices
better
- lots of tiny dwc3 fixes and updates for the IP block that is
showing up everywhere these days
- dts updates for new devices being supported
- other tiny janitorial and cleanups fixes for lots of different
USB drivers. Full details are in the shortlog.
All of these have been in linux-next for a while with no reported

This reverts commit 86d92f5465,
which fix the timeout issue for "Samsung Fit Flash".
But the commit affects not only "Samsung Fit Flash" but also other usb
storages that use the same controller and causes severe performance
regression.
# hdparm -t /dev/sda (without the quirk)
Timing buffered disk reads: 622 MB in 3.01 seconds = 206.66 MB/sec
# hdparm -t /dev/sda (with the quirk)
Timing buffered disk reads: 220 MB in 3.00 seconds = 73.32 MB/sec
The commit author mentioned that "Issue was reproduced after device has
bad block", so this quirk should be applied when we have the timeout
issue with a device that has bad blocks.
We revert the commit so that we apply this quirk by adding kernel
paramters using a bootloader or other ways when we really need it,
without the performance regression with devices that don't have the
issue.

DID_TARGET_FAILURE is internal to the SCSI layer. Drivers must not use it
because:
1. It's not propagated upwards, so SG IO/passthrough users will not see an
error and think a command was successful.
2. There is no handling for it in scsi_decide_disposition() so it results
in entering SCSI error handling.
It looks like the driver wanted a hard failure so this swaps it with
DID_BAD_TARGET which gives us that behavior. The error looks like it's for
a case where the target did not support a TMF we wanted to use (maybe not a
bad target but disappointing so close enough).

The third argument of usb_maxpacket(): in_out has been deprecated
because it could be derived from the second argument (e.g. using
usb_pipeout(pipe)).
N.B. function usb_maxpacket() was made variadic to accommodate the
transition from the old prototype with three arguments to the new one
with only two arguments (so that no renaming is needed). The variadic
argument is to be removed once all users of usb_maxpacket() get
migrated.

The function rio_karam_init() should return -ENOMEM instead of

Here is the big set of USB and Thunderbolt changes for 5.18-rc1.
Nothing major in here, just lots of little improvements and cleanups and
new device support. Highlights are:
- list iterator fixups for when we walk past the end of the list
(a common problem that was cut/pasted in almost all USB gadget
drivers)
- xen USB driver "hardening" for malicious hosts
- xhci driver updates and fixes for more hardware types
- xhci debug cable fixes to make it actually work again
- usb gadget audio driver improvements
- usb gadget storage fixes to work with OS-X
- lots of other small usb gadget fixes and updates
- USB DWC3 driver improvements for more hardware types
- Lots of other small USB driver improvements
- DTS updates for some USB platforms
Note, the DTS updates will have a merge conflict in your tree. The
fixup should be simple, but if not, I can provide a merged tree if
needed.
All of these have been in linux-next for a while with no reported
issues.

The kernel test robot found a problem with the ene_ub6250 subdriver in
usb-storage: It uses structures containing bitfields to represent
hardware bits in its SD_STATUS, MS_STATUS, and SM_STATUS bytes. This
is not safe; it presumes a particular bit ordering and it assumes the
compiler will not insert padding, neither of which is guaranteed.
This patch fixes the problem by changing the structures to simple u8
values, with the bitfields replaced by bitmask constants.

Now that each scsi_request is backed by a scsi_cmnd, there is no need to
indirect the CDB storage. Change all submitters of SCSI passthrough
requests to store the CDB information directly in the scsi_cmnd, and while
doing so allocate the full 32 bytes that cover all Linux supported SCSI
hosts instead of requiring dynamic allocation for > 16 byte CDBs. On
64-bit systems this does not change the size of the scsi_cmnd at all, while
on 32-bit systems it slightly increases it for now, but that increase will
be made up by the removal of the remaining scsi_request fields.

Set scsi_host_template.cmd_size instead of using the SCSI pointer for

uas_add_work() from struct uas_cmd_info * into struct scsi_cmnd * because
it is easier to convert a SCSI command pointer into a uas_cmd_info pointer
than the other way around.

Two people have reported (and mentioned numerous other reports on the
web) that VIA's VL817 USB-SATA bridge does not work with the uas
driver. Typical log messages are:
[ 3606.232149] sd 14:0:0:0: [sdg] tag#2 uas_zap_pending 0 uas-tag 1 inflight: CMD
[ 3606.232154] sd 14:0:0:0: [sdg] tag#2 CDB: Write(16) 8a 00 00 00 00 00 18 0c c9 80 00 00 00 80 00 00

[ 3606.328584] scsi host14: uas_eh_device_reset_handler success
Surprisingly, the devices do seem to work okay for some other people.
The cause of the differing behaviors is not known.
In the hope of getting the devices to work for the most users, even at
the possible cost of degraded performance for some, this patch adds an
unusual_devs entry for the VL817 to block it from binding to the uas
driver by default. Users will be able to override this entry by means
of a module parameter, if they want.

the final removal of scsi_ioctl, which has been deprecated for over a

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This series consists of the usual driver updates (ufs, qla2xxx,
target, smartpqi, lpfc, mpt3sas).
The core change causing the most churn was replacing the command
request field request with a macro, allowing us to offset map to it
and remove the redundant field; the same was also done for the tag
field.
The most impactful change is the final removal of scsi_ioctl, which
has been deprecated for over a decade"
