commit 9b83a1c301ad6d24988a128c69b42cbaaf537d82 upstream.
WORLDE Controller KS49 or Prodipe MIDI 49C USB controller
cause a -EPROTO error, a communication restart and loop again.
This issue has already been fixed for KS25.
https://lore.kernel.org/patchwork/patch/753077/
I just add device 201 for KS49 in quirks.c to get it works.

commit f9a5b4f58b280c1d26255376713c132f93837621 upstream.
The steps taken by usb core to set a new interface is very different from
what is done on the xHC host side.
xHC hardware will do everything in one go. One command is used to set up
new endpoints, free old endpoints, check bandwidth, and run the new
endpoints.
All this is done by xHC when usb core asks the hcd to check for
available bandwidth. At this point usb core has not yet flushed the old
endpoints, which will cause use-after-free issues in xhci driver as
queued URBs are cancelled on a re-allocated endpoint.
To resolve this add a call to usb_disable_interface() which will flush
the endpoints before calling usb_hcd_alloc_bandwidth()
Additional checks in xhci driver will also be implemented to gracefully
handle stale URB cancel on freed and re-allocated endpoints

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.

commit f3dc41c5d22b2ca14a0802a65d8cdc33a3882d4e upstream.
usb_hc_died() should only be called once, and with the primary HCD
as parameter. It will mark both primary and secondary hcd's dead.
Remove the extra call to usb_cd_died with the shared hcd as parameter.

[ Upstream commit 5d111f5190848d6fb1c414dc57797efea3526a2f ]
wait_for_connected() wait till a port change status to
USB_PORT_STAT_CONNECTION, but this is not possible if
the port is unpowered. The loop will only exit at timeout.
Such case take place if an over-current incident happen
while system is in S3. Then during resume wait_for_connected()
will wait 2s, which may be noticeable by the user.

commit 249a32b7eeb3edb6897dd38f89651a62163ac4ed upstream.
Based on USB2.0 Spec Section 11.12.5,
"If a hub has per-port power switching and per-port current limiting,
an over-current on one port may still cause the power on another port
to fall below specific minimums. In this case, the affected port is
placed in the Power-Off state and C_PORT_OVER_CURRENT is set for the
port, but PORT_OVER_CURRENT is not set."
so let's check C_PORT_OVER_CURRENT too for over current condition.

commit bba57eddadda936c94b5dccf73787cb9e159d0a5 upstream.
Corsair Strafe appears to suffer from the same issues
as the Corsair Strafe RGB.
Apply the same quirks (control message delay and init delay)
that the RGB version has to 1b1c:1b15.
With these quirks in place the keyboard works correctly upon
booting the system, and no longer requires reattaching the device.

commit 6e01827ed93947895680fbdad68c072a0f4e2450 upstream.
Some low-speed and full-speed devices (for example, bluetooth)
do not have time to initialize. For them, ETIMEDOUT is a valid error.
We need to give them another try. Otherwise, they will
never be initialized correctly and in dmesg will be messages
"Bluetooth: hci0 command 0x1002 tx timeout" or similars.

commit fb5ee84ea72c5f1b6cabdd1c9d6e8648995ca7c6 upstream.
Some non-compliant high-speed USB devices have bulk endpoints with a
1024-byte maxpacket size. Although such endpoints don't work with
xHCI host controllers, they do work with EHCI controllers. We used to
accept these invalid sizes (with a warning), but we no longer do
because of an unintentional change introduced by commit aed9d65ac327
("USB: validate wMaxPacketValue entries in endpoint descriptors").
This patch restores the old behavior, so that people with these
peculiar devices can use them without patching their kernels by hand.

commit 83a62c51ba7b3c0bf45150c4eac7aefc6c785e94 upstream.
On chromebooks we depend on wakeup count to identify the wakeup source.
But currently USB devices do not increment the wakeup count when they
trigger the remote wake. This patch addresses the same.
Resume condition is reported differently on USB 2.0 and USB 3.0 devices.
On USB 2.0 devices, a wake capable device, if wake enabled, drives
resume signal to indicate a remote wake (USB 2.0 spec section 7.1.7.7).
The upstream facing port then sets C_PORT_SUSPEND bit and reports a
port change event (USB 2.0 spec section 11.24.2.7.2.3). Thus if a port
has resumed before driving the resume signal from the host and
C_PORT_SUSPEND is set, then the device attached to the given port might
be the reason for the last system wakeup. Increment the wakeup count for
the same.
On USB 3.0 devices, a function may signal that it wants to exit from device
suspend by sending a Function Wake Device Notification to the host (USB3.0
spec section 8.5.6.4) Thus on receiving the Function Wake, increment the
wakeup count.

commit 64627388b50158fd24d6ad88132525b95a5ef573 upstream.
USB3 hubs don't support global suspend.
USB3 specification 10.10, Enhanced SuperSpeed hubs only support selective
suspend and resume, they do not support global suspend/resume where the
hub downstream facing ports states are not affected.
When system enters hibernation it first enters freeze process where only
the root hub enters suspend, usb_port_suspend() is not called for other
devices, and suspend status flags are not set for them. Other devices are
expected to suspend globally. Some external USB3 hubs will suspend the
downstream facing port at global suspend. These devices won't be resumed
at thaw as the suspend status flag is not set.
A USB3 removable hard disk connected through a USB3 hub that won't resume
at thaw will fail to synchronize SCSI cache, return “cmd cmplt err -71”
error, and needs a 60 seconds timeout which causing system hang for 60s
before the USB host reset the port for the USB3 removable hard disk to
recover.
Fix this by always calling usb_port_suspend() during freeze for USB3
devices.

commit cb88a0588717ba6c756cb5972d75766b273a6817 upstream.
Corsair Strafe RGB keyboard does not respond to usb control messages
sometimes and hence generates timeouts.
Commit de3af5bf259d ("usb: quirks: add delay init quirk for Corsair
Strafe RGB keyboard") tried to fix those timeouts by adding
USB_QUIRK_DELAY_INIT.
Unfortunately, even with this quirk timeouts of usb_control_msg()
can still be seen, but with a lower frequency (approx. 1 out of 15):
[ 29.103520] usb 1-8: string descriptor 0 read error: -110
[ 34.363097] usb 1-8: can't set config #1, error -110
Adding further delays to different locations where usb control
messages are issued just moves the timeouts to other locations,
e.g.:
[ 35.400533] usbhid 1-8:1.0: can't add hid device: -110
[ 35.401014] usbhid: probe of 1-8:1.0 failed with error -110
The only way to reliably avoid those issues is having a pause after
each usb control message. In approx. 200 boot cycles no more timeouts
were seen.
Addionaly, keep USB_QUIRK_DELAY_INIT as it turned out to be necessary
to have the delay in hub_port_connect() after hub_port_init().
The overall boot time seems not to be influenced by these additional
delays, even on fast machines and lightweight distributions.

commit 07b9f12864d16c3a861aef4817eb1efccbc5d0e6 upstream.
USB 3.1 devices are not detected as 3.1 capable since 4.15-rc3 due to a
off by one in commit 81cf4a45360f ("USB: core: Add type-specific length
check of BOS descriptors")
It uses USB_DT_USB_SSP_CAP_SIZE() to get SSP capability size which takes
the zero based SSAC as argument, not the actual count of sublink speed
attributes.
USB3 spec 9.6.2.5 says "The number of Sublink Speed Attributes = SSAC + 1."
The type-specific length check patch was added to stable and needs to be
fixed there as well

commit 48a4ff1c7bb5a32d2e396b03132d20d552c0eca7 upstream.
A malicious USB device with crafted descriptors can cause the kernel
to access unallocated memory by setting the bNumInterfaces value too
high in a configuration descriptor. Although the value is adjusted
during parsing, this adjustment is skipped in one of the error return
paths.
This patch prevents the problem by setting bNumInterfaces to 0
initially. The existing code already sets it to the proper value
after parsing is complete.

commit 57999d1107c1e60c2ca7088f2ac0f819e2f554b3 upstream.
There used to be an integer overflow check in proc_do_submiturb() but
we removed it. It turns out that it's still required. The
uurb->buffer_length variable is a signed integer and it's controlled by
the user. It can lead to an integer overflow when we do:
num_sgs = DIV_ROUND_UP(uurb->buffer_length, USB_SG_SIZE);
If we strip away the macro then that line looks like this:
num_sgs = (uurb->buffer_length + USB_SG_SIZE - 1) / USB_SG_SIZE;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
It's the first addition which can overflow.

commit 973593a960ddac0f14f0d8877d2d0abe0afda795 upstream.
Sometimes the USB device gets confused about the state of the initialization and
the connection fails. In particular, the device thinks that it's already set up
and running while the host thinks the device still needs to be configured. To
work around this issue, power-cycle the hub's output to issue a sort of "reset"
to the device. This makes the device restart its state machine and then the
initialization succeeds.
This fixes problems where the kernel reports a list of errors like this:
usb 1-1.3: device not accepting address 19, error -71
The end result is a non-functioning device. After this patch, the sequence
becomes like this:
usb 1-1.3: new high-speed USB device number 18 using ci_hdrc
usb 1-1.3: device not accepting address 18, error -71
usb 1-1.3: new high-speed USB device number 19 using ci_hdrc

commit 2ef47001b3ee3ded579b7532ebdcf8680e4d8c54 upstream.
The USB kerneldoc says that the actual_length field "is read in
non-iso completion functions", but the usbfs driver uses it for all
URB types in processcompl(). Since not all of the host controller
drivers set actual_length for isochronous URBs, programs using usbfs
with some host controllers don't work properly. For example, Minas
reports that a USB camera controlled by libusb doesn't work properly
with a dwc2 controller.
It doesn't seem worthwhile to change the HCDs and the documentation,
since the in-kernel USB class drivers evidently don't rely on
actual_length for isochronous transfers. The easiest solution is for
usbfs to calculate the actual_length value for itself, by adding up
the lengths of the individual packets in an isochronous transfer.

commit 1ac7db63333db1eeff901bfd6bbcd502b4634fa4 upstream.
If the connect status change is set during reset signaling, but
the status remains connected just retry port reset.
This solves an issue with connecting a 90W HP Thunderbolt 3 dock
with a Lenovo Carbon x1 (5th generation) which causes a 30min loop
of a high speed device being re-discovererd before usb ports starts
working.
[...]
[ 389.023845] usb 3-1: new high-speed USB device number 55 using xhci_hcd
[ 389.491841] usb 3-1: new high-speed USB device number 56 using xhci_hcd
[ 389.959928] usb 3-1: new high-speed USB device number 57 using xhci_hcd
[...]
This is caused by a high speed device that doesn't successfully go to the
enabled state after the second port reset. Instead the connection bounces
(connected, with connect status change), bailing out completely from
enumeration just to restart from scratch.

commit 2811501e6d8f5747d08f8e25b9ecf472d0dc4c7d upstream.
This keyboard doesn't implement Get String descriptors properly even
though string indexes are valid. What happens is that when requesting
for the String descriptor, the device disconnects and
reconnects. Without this quirk, this loop will continue forever.

commit 1c0edc3633b56000e18d82fc241e3995ca18a69e upstream.
Andrey used the syzkaller fuzzer to find an out-of-bounds memory
access in usb_get_bos_descriptor(). The code wasn't checking that the
next usb_dev_cap_header structure could fit into the remaining buffer
space.
This patch fixes the error and also reduces the bNumDeviceCaps field
in the header to match the actual number of capabilities found, in
cases where there are fewer than expected.

commit 845d584f41eac3475c21e4a7d5e88d0f6e410cf7 upstream.
Taking the uurb->buffer_length userspace passes in as a maximum for the
actual urbs transfer_buffer_length causes 2 serious issues:
1) It breaks isochronous support for all userspace apps using libusb,
as existing libusb versions pass in 0 for uurb->buffer_length,
relying on the kernel using the lenghts of the usbdevfs_iso_packet_desc
descriptors passed in added together as buffer length.
This for example causes redirection of USB audio and Webcam's into
virtual machines using qemu-kvm to no longer work. This is a userspace
ABI break and as such must be reverted.
Note that the original commit does not protect other users / the
kernels memory, it only stops the userspace process making the call
from shooting itself in the foot.
2) It may cause the kernel to program host controllers to DMA over random
memory. Just as the devio code used to only look at the iso_packet_desc
lenghts, the host drivers do the same, relying on the submitter of the
urbs to make sure the entire buffer is large enough and not checking
transfer_buffer_length.
But the "USB: devio: Don't corrupt user memory" commit now takes the
userspace provided uurb->buffer_length for the buffer-size while copying
over the user-provided iso_packet_desc lengths 1:1, allowing the user
to specify a small buffer size while programming the host controller to
dma a lot more data.
(Atleast the ohci, uhci, xhci and fhci drivers do not check
transfer_buffer_length for isoc transfers.)
This reverts commit fa1ed74eb1c2 ("USB: devio: Don't corrupt user memory")
fixing both these issues.

commit bd7a3fe770ebd8391d1c7d072ff88e9e76d063eb upstream.
Andrey Konovalov reported a possible out-of-bounds problem for a USB interface
association descriptor. He writes:
It seems there's no proper size check of a USB_DT_INTERFACE_ASSOCIATION
descriptor. It's only checked that the size is >= 2 in
usb_parse_configuration(), so find_iad() might do out-of-bounds access
to intf_assoc->bInterfaceCount.
And he's right, we don't check for crazy descriptors of this type very well, so
resolve this problem. Yet another issue found by syzkaller...

Commit e0429362ab15
("usb: Add device quirk for Logitech HD Pro Webcams C920 and C930e")
introduced quirk to workaround an issue with some Logitech webcams.
The workaround is introducing delay for some USB operations.
According to our testing, delay introduced by original commit
is not long enough and in rare cases we still see issues described
by the aforementioned commit.
This patch increases delays introduced by original commit.
Having this patch applied we do not see those problems anymore.

Investigation using kgdb() found that the wait queue that was passed
into wake_up() had been freed (it was filled with slub_debug poison).
I analyzed and instrumented the code and reproduced. My current
belief is that this is happening:
1. async_completed() is called (from IRQ). Moves "as" onto the
completed list.
2. On another CPU, proc_reapurbnonblock_compat() calls
async_getcompleted(). Blocks on spinlock.
3. async_completed() releases the lock; keeps running; gets blocked
midway through wake_up().
4. proc_reapurbnonblock_compat() => async_getcompleted() gets the
lock; removes "as" from completed list and frees it.
5. usbdev_release() is called. Frees "ps".
6. async_completed() finally continues running wake_up(). ...but
wake_up() has a pointer to the freed "ps".
The instrumentation that led me to believe this was based on adding
some trace_printk() calls in a select few functions and then using
kdb's "ftdump" at crash time. The trace follows (NOTE: in the trace
below I cheated a little bit and added a udelay(1000) in
async_completed() after releasing the spinlock because I wanted it to
trigger quicker):
<...>-2104 0d.h2 13759034us!: async_completed at start: as=ffffffc0cc638200
mtpd-2055 3.... 13759356us : async_getcompleted before spin_lock_irqsave
mtpd-2055 3d..1 13759362us : async_getcompleted after list_del_init: as=ffffffc0cc638200
mtpd-2055 3.... 13759371us+: proc_reapurbnonblock_compat: free_async(ffffffc0cc638200)
mtpd-2055 3.... 13759422us+: async_getcompleted before spin_lock_irqsave
mtpd-2055 3.... 13759479us : usbdev_release at start: ps=ffffffc0cc042080

mtpd-2055 3.... 13759497us!: usbdev_release after kfree(ps): ps=ffffffc0cc042080
<...>-2104 0d.h2 13760294us : async_completed before wake_up(): as=ffffffc0cc638200
To fix this problem we can just move the wake_up() under the ps->lock.
There should be no issues there that I'm aware of.

commit ed18c5fa945768a9bec994e786edbbbc7695acf6 upstream.
This optimization significantly reduces xhci driver load time.
In ACPI tables the acpi companion port devices are children of
the hub device. The port devices are identified by their port number
returned by the ACPI _ADR method.
_ADR 0 is reserved for the root hub device.
The current implementation to find a acpi companion port device
loops through all acpi port devices under that parent hub, evaluating
their _ADR method each time a new port device is added.
for a xHC controller with 25 ports under its roothub it
will end up invoking ACPI bytecode 625 times before all ports
are ready, making it really slow.
The _ADR values are already read and cached earler. So instead of
running the bytecode again we can check the cached _ADR value first,
and then fall back to the old way.
As one of the more significant changes, the xhci load time on
Intel kabylake reduced by 70%, (28ms) from
initcall xhci_pci_init+0x0/0x49 returned 0 after 39537 usecs
to
initcall xhci_pci_init+0x0/0x49 returned 0 after 11270 usecs

commit e788787ef4f9c24aafefc480a8da5f92b914e5e6 upstream.
Certain HP keyboards would keep inputting a character automatically which
is the wake-up key after S3 resume
On some AMD platforms USB host fails to respond (by holding resume-K) to
USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures
that resume is signaled for at least 20 ms (TDRSMDN), which is defined in
USB 2.0 spec. The result is that the keyboard is out of function.
In SNPS USB design, the host responds to the resume request only after
system gets back to S0 and the host gets to functional after the internal
HW restore operation that is more than 1 second after the initial resume
request from the USB device.
As a workaround for specific keyboard ID(HP Keyboards), applying port reset
after resume when the keyboard is plugged in.

commit 2eac13624364db5b5e1666ae0bb3a4d36bc56b6e upstream.
While unlink an urb, if the urb has been programmed in the controller,
the controller driver might do some hw related actions to tear down the
urb.
Currently usb_hcd_flush_endpoint() passes each urb from the head of the
endpoint's urb_list to the controller driver, which could make the
controller driver think each urb has been programmed and take the
unnecessary actions for each urb.
This patch changes the behavior in usb_hcd_flush_endpoint() to pass the
urbs from the tail of the list, to avoid any unnecessary actions in an
controller driver.

commit 94c43b9897abf4ea366ed4dba027494e080c7050 upstream.
Some buggy USB disk adapters disconnect and reconnect multiple times
during the enumeration procedure. This may lead to a device
connecting at full speed instead of high speed, because when the USB
stack sees that a device isn't able to enumerate at high speed, it
tries to hand the connection over to a full-speed companion
controller.
The logic for doing this is careful to check that the device is still
connected. But this check is inadequate if the device disconnects and
reconnects before the check is done. The symptom is that a device
works, but much more slowly than it is capable of operating.
The situation was made worse recently by commit 22547c4cc4fe ("usb:
hub: Wait for connection to be reestablished after port reset"), which
increases the delay following a reset before a disconnect is
recognized, thus giving the device more time to reconnect.
This patch makes the check more robust. If the device was
disconnected at any time during enumeration, we will now skip the
full-speed handover.

commit 6836796de4019944f4ba4c99a360e8250fd2e735 upstream.
The USB core and sysfs will attempt to enumerate certain parameters
which are unsupported by the au0828 - causing inconsistent behavior
and sometimes causing the chip to reset. Avoid making these calls.
This problem manifested as intermittent cases where the au8522 would
be reset on analog video startup, in particular when starting up ALSA
audio streaming in parallel - the sysfs entries created by
snd-usb-audio on streaming startup would result in unsupported control
messages being sent during tuning which would put the chip into an
unknown state.
