commit 8e71a322fd upstream.
If a device is halted and reuturns a STALL, then the halted endpoint
needs to be cleared both on the host and device side. The host
side halt is cleared by issueing a xhci reset endpoint command. The device side
is cleared with a ClearFeature(ENDPOINT_HALT) request, which should
be issued by the device driver if a URB reruen -EPIPE.
Previously we cleared the host side halt after the device side was cleared.
To make sure the host side halt is cleared in time we want to issue the
reset endpoint command immedialtely when a STALL status is encountered.
Otherwise we end up not following the specs and not returning -EPIPE
several times in a row when trying to transfer data to a halted endpoint.

commit a1377e5397 upstream.
When system is being suspended, if host device is not allowed to do wakeup,
xhci_suspend() needs to clear all root port wake on bits. Otherwise, some
platforms may generate spurious wakeup, even if PCI PME# is disabled.
The initial commit ff8cbf250b ("xhci: clear root port wake on bits"),
which also got into stable, turned out to not work correctly and had to
be reverted, and is now rewritten.

commit c3492dbfa1 upstream.
A halted endpoint ring must first be reset, then move the ring
dequeue pointer past the problematic TRB. If we start the ring too
early after reset, but before moving the dequeue pointer we
will end up executing the same problematic TRB again.
As we always issue a set transfer dequeue command after a reset
endpoint command we can skip starting endpoint rings at reset endpoint
command completion.
Without this fix we end up trying to handle the same faulty TD for
contol endpoints. causing timeout, and failing testusb ctrl_out write
tests.

commit 93c9bf4d18 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.

which does not trigger that often.
The following scenario is still possible:

hrtimer_start(&x->t);

expires:
t->function();
lock(&x->lock);
lock(&x->lock); if (!hrtimer_queued(&x->t))

ret = HRTIMER_RESTART;
-> hrtimer_forward_now(...)
} else
ret = HRTIMER_NORESTART;
unlock(&x->lock);
and the timer callback returns HRTIMER_RESTART for an armed timer. This
is wrong and we run into the BUG_ON() in __run_hrtimer().

Old code in ehci-hcd tries to expedite disabling endpoints after the
controller has stopped, by destroying the endpoint's associated QH
without first unlinking the QH. This was necessary back when the
driver wasn't so careful about keeping track of the controller's
state.
But now we are careful about it, and the driver knows that when the
controller isn't running, no unlinking delay is needed. Furthermore,
skipping the unlink step will trigger a BUG() in qh_destroy() when the
preceding QH is released, because the link pointer will be non-NULL.
Removing the lines that skip the unlinking step and go directly to
QH_STATE_IDLE fixes the problem.

commit c80b4495c6 upstream.
This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB-
SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The
US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI
chain to be accessed. Without it only the (single) device with SCSI ID 0
can be used.
The standalone converter sold by Entrega had model number U1-SC25. Xircom
acquired Entrega and re-branded the product line PortGear. The PortGear USB
to SCSI Converter (model PGSCSI) is internally identical to the Entrega
product, but later models may use a different USB ID. The Entrega-branded
units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and
Macintosh drivers also support 085A:0028.
Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac
(8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as
a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may
have initially used the same ID as the standalone U1-SC25 (1645:0007), but
later production used 085A:0026.
My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133
probably also exist.
This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows
driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I
couldn't find any mention of that actually existing in the wild; perhaps it
was cancelled before release?

I don't have a USBConnect 2000, but based on the other entries for Shuttle/
SCM-based converters this patch is very likely correct. I used 0x0000 and
0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which
bcdDevice value the product uses.

commit c66f1c62e8 upstream.
The Iomega Jaz USB Adapter is a SCSI-USB converter cable. The hardware
seems to be identical to e.g. the Microtech XpressSCSI, using a Shuttle/
SCM chip set. However its firmware restricts it to only work with Jaz
drives.
On connecting the cable a message like this appears four times in the log:
reset full speed USB device number 4 using uhci_hcd
That's non-fatal but the US_FL_SINGLE_LUN quirk fixes it.

commit c605f3cdff upstream.
During surprise device hotplug removal tests, it was observed that
hub_events may try to call usb_lock_device on a device that has already
been freed. Protect the usb_device by taking out a reference (under the
hub_event_lock) when hub_events pulls it off the list, returning the
reference after hub_events is finished using it.

commit 96044694b8 upstream.
Resuming from hibernate (S4) will restart and re-initialize xHC.
The device contexts are freed and will be re-allocated later during device reset.
Usb core will disable link pm in device resume before device reset, which will
try to change the max exit latency, accessing the device contexts before they are re-allocated.
There is no need to zero (disable) the max exit latency when disabling hw lpm
for a freshly re-initialized xHC. So check that device context exists before
doing anything. The max exit latency will be set again after device reset when usb core
enables the link pm.

If xhci initialization fails before the roothub bandwidth
domains (xhci->rh_bw[i]) are allocated it will oops when
trying to access rh_bw members in xhci_mem_cleanup().

commit 96908589a8 upstream.
Commit 71c731a (usb: host: xhci: Fix Compliance Mode
on SN65LVP3502CP Hardware) implemented a workaround
for a known issue with Texas Instruments' USB 3.0
redriver IC but it left a condition where any xHCI
host would be taken out of reset if port was placed
in compliance mode and there was no device connected
to the port.
That condition would trigger a fake connection to a
non-existent device so that usbcore would trigger a
warm reset of the port, thus taking the link out of
reset.
This has the side-effect of preventing any xHCI host
connected to a Linux machine from starting and running
the USB 3.0 Electrical Compliance Suite because the
port will mysteriously taken out of compliance mode
and, thus, xHCI won't step through the necessary
compliance patterns for link validation.
This patch fixes the issue by just adding a missing
check for XHCI_COMP_MODE_QUIRK inside
xhci_hub_report_usb3_link_state() when PORT_CAS isn't
set.
This patch should be backported to all kernels containing
commit 71c731a.

that it not only moved some PIDs from option to zte_ev but also added
some new ones.
