commit c80b4495c61636edc58fe1ce300f09f24db28e10 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?

commit b6a3ed677991558ce09046397a7c4d70530d15b3 upstream.
Hi,
The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g.
iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM
Microsystems chips. Only the connectors differ; both have the same USB ID.
The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other
than 0.
I don't have one of these, 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 products use.

commit c66f1c62e85927357e7b3f4c701614dcb5c498a2 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 c605f3cdff53a743f6d875b76956b239deca1272 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 96908589a8b2584b1185f834d365f5cc360e8226 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.

commit fed33afce0eda44a46ae24d93aec1b5198c0bac4 upstream.
Currently, we disable pm_runtime before all register
accesses are done, this is dangerous and might lead
to abort exceptions due to the driver trying to access
a register which is clocked by a clock which was long
gated.
Fix that by moving pm_runtime_put_sync() and pm_runtime_disable()
as the last thing we do before returning from our ->remove()
method.

commit 049255f51644c1105775af228396d187402a5934 upstream.
Sierra Wireless Direct IP devices using the 68A3 product ID
can be configured for modes including a CDC ECM class function.
The known example uses interface numbers 12 and 13 for the ECM
control and data interfaces respectively, consistent with CDC
MBIM function interface numbering on other Sierra devices.
It seems cleaner to restrict this driver to the ff/ff/ff
vendor specific interfaces rather than increasing the already
long interface number blacklist. This should be more future
proof if Sierra adds more class functions using interface
numbers not yet in the blacklist.

commit 6817ae225cd650fb1c3295d769298c38b1eba818 upstream.
This patch fixes a potential security issue in the whiteheat USB driver
which might allow a local attacker to cause kernel memory corrpution. This
is due to an unchecked memcpy into a fixed size buffer (of 64 bytes). On
EHCI and XHCI busses it's possible to craft responses greater than 64
bytes leading a buffer overflow.

commit 365038d83313951d6ace15342eb24624bbef1666 upstream.
When we manually need to move the TR dequeue pointer we need to set the
correct cycle bit as well. Previously we used the trb pointer from the
last event received as a base, but this was changed in
commit 1f81b6d22a59 ("usb: xhci: Prefer endpoint context dequeue pointer")
to use the dequeue pointer from the endpoint context instead
It turns out some Asmedia controllers advance the dequeue pointer
stored in the endpoint context past the event triggering TRB, and
this messed up the way the cycle bit was calculated.
Instead of adding a quirk or complicating the already hard to follow cycle bit
code, the whole cycle bit calculation is now simplified and adapted to handle
event and endpoint context dequeue pointer differences.
Fixes: 1f81b6d22a59 ("usb: xhci: Prefer endpoint context dequeue pointer")

commit a40178b2fa6ad87670fb1e5fa4024db00c149629 upstream.
Problem Summary: Problem has been observed generally with PM states
where VBUS goes off during suspend. There are some SS USB devices which
take longer time for link training compared to many others. Such
devices fail to reconnect with same old address which was associated
with it before suspend.
When system resumes, at some point of time (dpm_run_callback->
usb_dev_resume->usb_resume->usb_resume_both->usb_resume_device->
usb_port_resume) SW reads hub status. If device is present,
then it finishes port resume and re-enumerates device with same
address. If device is not present then, SW thinks that device was
removed during suspend and therefore does logical disconnection
and removes all the resource allocated for this device.
Now, if I put sufficient delay just before root hub status read in
usb_resume_device then, SW sees always that device is present. In normal
course(without any delay) SW sees that no device is present and then SW
removes all resource associated with the device at this port. In the
latter case, after sometime, device says that hey I am here, now host
enumerates it, but with new address.
Problem had been reproduced when I connect verbatim USB3.0 hard disc
with my STiH407 XHCI host running with 3.10 kernel.
I see that similar problem has been reported here.
https://bugzilla.kernel.org/show_bug.cgi?id=53211
Reading above it seems that bug was not in 3.6.6 and was present in 3.8
and again it was not present for some in 3.12.6, while it was present
for few others. I tested with 3.13-FC19 running at i686 desktop, problem
was still there. However, I was failed to reproduce it with 3.16-RC4
running at same i686 machine. I would say it is just a random
observation. Problem for few devices is always there, as I am unable to
find a proper fix for the issue.
So, now question is what should be the amount of delay so that host is
always able to recognize suspended device after resume.
XHCI specs 4.19.4 says that when Link training is successful, port sets
CSC bit to 1. So if SW reads port status before successful link
training, then it will not find device to be present. USB Analyzer log
with such buggy devices show that in some cases device switch on the
RX termination after long delay of host enabling the VBUS. In few other
cases it has been seen that device fails to negotiate link training in
first attempt. It has been reported till now that few devices take as
long as 2000 ms to train the link after host enabling its VBUS and
RX termination. This patch implements a 2000 ms timeout for CSC bit to set
ie for link training. If in a case link trains before timeout, loop will
exit earlier.
This patch implements above delay, but only for SS device and when
persist is enabled.
So, for the good device overhead is almost none. While for the bad
devices penalty could be the time which it take for link training.
But, If a device was connected before suspend, and was removed
while system was asleep, then the penalty would be the timeout ie
2000 ms.
Results:
Verbatim USB SS hard disk connected with STiH407 USB host running 3.10
Kernel resumes in 461 msecs without this patch, but hard disk is
assigned a new device address. Same system resumes in 790 msecs with
this patch, but with old device address.

commit 977dcfdc60311e7aa571cabf6f39c36dde13339e upstream.
This patch fixes a bug in ohci-hcd. When an URB is unlinked, the
corresponding Endpoint Descriptor is added to the ed_rm_list and taken
off the hardware schedule. Once the ED is no longer visible to the
hardware, finish_unlinks() handles the URBs that were unlinked or have
completed. If any URBs remain attached to the ED, the ED is added
back to the hardware schedule -- but only if the controller is
running.
This fails when a controller dies. A non-empty ED does not get added
back to the hardware schedule and does not remain on the ed_rm_list;
ohci-hcd loses track of it. The remaining URBs cannot be unlinked,
which causes the USB stack to hang.
The patch changes finish_unlinks() so that non-empty EDs remain on
the ed_rm_list if the controller isn't running. This requires moving
some of the existing code around, to avoid modifying the ED's hardware
fields more than once.

commit bb86cf569bbd7ad4dce581a37c7fbd748057e9dc upstream.
When using USB 3.0 pen drive with the [AMD] FCH USB XHCI Controller
[1022:7814], the second hotplugging will experience the USB 3.0 pen
drive is recognized as high-speed device. After bisecting the kernel,
I found the commit number 41e7e056cdc662f704fa9262e5c6e213b4ab45dd
(USB: Allow USB 3.0 ports to be disabled.) causes the bug. After doing
some experiments, the bug can be fixed by avoiding executing the function
hub_usb3_port_disable(). Because the port status with [AMD] FCH USB
XHCI Controlleris [1022:7814] is already in RxDetect
(I tried printing out the port status before setting to Disabled state),
it's reasonable to check the port status before really executing
hub_usb3_port_disable().
Fixes: 41e7e056cdc6 (USB: Allow USB 3.0 ports to be disabled.)

commit d6236f6d1d885aa19d1cd7317346fe795227a3cc upstream.
The system suspend flow as following:
1, Freeze all user processes and kenrel threads.
2, Try to suspend all devices.
2.1, If pci device is in RPM suspended state, then pci driver will try
to resume it to RPM active state in the prepare stage.
2.2, xhci_resume function calls usb_hcd_resume_root_hub to queue two
workqueue items to resume usb2&usb3 roothub devices.
2.3, Call suspend callbacks of devices.
2.3.1, All suspend callbacks of all hcd's children, including
roothub devices are called.
2.3.2, Finally, hcd_pci_suspend callback is called.
Due to workqueue threads were already frozen in step 1, the workqueue
items can't be scheduled, and the roothub devices can't be resumed in
this flow. The HCD_FLAG_WAKEUP_PENDING flag which is set in
usb_hcd_resume_root_hub won't be cleared. Finally,
hcd_pci_suspend will return -EBUSY, and system suspend fails.
The reason why this issue doesn't show up very often is due to that
choose_wakeup will be called in step 2.3.1. In step 2.3.1, if
udev->do_remote_wakeup is not equal to device_may_wakeup(&udev->dev), then
udev will resume to RPM active for changing the wakeup settings. This
has been a lucky hit which hides this issue.
For some special xHCI controllers which have no USB2 port, then roothub
will not match hub driver due to probe failed. Then its
do_remote_wakeup will be set to zero, and we won't be as lucky.
xhci driver doesn't need to resume roothub devices everytime like in
the above case. It's only needed when there are pending event TRBs.

commit 3213b151387df0b95f4eada104f68eb1c1409cb3 upstream.
The transfer burst count (TBC) field in xhci 1.0 hosts should be set
to the number of bursts needed to transfer all packets in a isoc TD.
Supported values are 0-2 (1 to 3 bursts per service interval).
Formula for TBC calculation is given in xhci spec section 4.11.2.3:
TBC = roundup( Transfer Descriptor Packet Count / Max Burst Size +1 ) - 1
This patch should be applied to stable kernels since 3.0 that contain
the commit 5cd43e33b9519143f06f507dd7cbee6b7a621885

Fix NULL-pointer dereference when probing an interface with no
endpoints.
These devices have two bulk endpoints per interface, but this avoids
crashing the kernel if a user forces a non-FTDI device to be probed.
Note that the iterator variable was made unsigned in order to avoid
a maybe-uninitialized compiler warning for ep_desc after the loop.

commit f0688c8b81d2ea239c3fb0b848f623b579238d99 upstream.
If the descriptors do not need any strings and user space sends empty
set of strings, the ffs->stringtabs field remains NULL. Thus
*ffs->stringtabs in functionfs_bind leads to a NULL pointer
dereferenece.
The bug was introduced by commit [fd7c9a007f: “use usb_string_ids_n()”].
While at it, remove double initialisation of lang local variable in
that function.
ffs->strings_count does not need to be checked in any way since in
the above scenario it will remain zero and usb_string_ids_n() is
a no-operation when colled with 0 argument.

commit c03890ff5e24a4bf59059f2d179f427559b7330a upstream.
A recent patch that purported to fix firmware download on big-endian
machines failed to add the corresponding sparse annotation to the
i2c-header. This was reported by the kbuild test robot.
Adding the appropriate annotation revealed another endianess bug related
to the i2c-header Size-field in a code path that is exercised when the
firmware is actually being downloaded (and not just verified and left
untouched unless older than the firmware at hand).
This patch adds the required sparse annotation to the i2c-header and
makes sure that the Size-field is sent in little-endian byte order
during firmware download also on big-endian machines.
Note that this patch is only compile-tested, but that there is no
functional change for little-endian systems.

commit 140cb81ac8c625942a1d695875932c615767a526 upstream.
The current ACM runtime-suspend implementation is broken in several
ways:
Firstly, it buffers only the first write request being made while
suspended -- any further writes are silently dropped.
Secondly, writes being dropped also leak write urbs, which are never
reclaimed (until the device is unbound).
Thirdly, even the single buffered write is not cleared at shutdown
(which may happen before the device is resumed), something which can
lead to another urb leak as well as a PM usage-counter leak.
Fix this by implementing a delayed-write queue using urb anchors and
making sure to discard the queue properly at shutdown.

Fix race between write() and resume() due to improper locking that could
lead to writes being reordered.
Resume must be done atomically and susp_count be protected by the
write_lock in order to prevent racing with write(). This could otherwise
lead to writes being reordered if write() grabs the write_lock after
susp_count is decremented, but before the delayed urb is submitted.
