[ Upstream commit cd8db057e93ddaacbec025b567490555d2bca280 ]

Make sure to detect short transfers when reading a device register.

The modem-status handling had sufficient error checks in place, but move
handling of short transfers into the register accessor function itself
for consistency.

[ Upstream commit 0d130367abf582e7cbf60075c2a7ab53817b1d14 ]

Make sure to log an error on short transfers when reading a device
register.

Also clear the provided buffer (which if often an uninitialised
automatic variable) on errors as the driver currently does not bother to
check for errors.

commit ed62ca2f4f51c17841ea39d98c0c409cb53a3e10 upstream.

While running reboot tests w/ a specific set of USB devices (and
slub_debug enabled), I found that once every few hours my device would
be crashed with a stack that looked like this:

[   14.012445] BUG: spinlock bad magic on CPU#0, modprobe/2091

[   14.012572] [&lt;....&gt;] gic_handle_irq+0xcc/0x18c

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() =&gt; 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):

&lt;...&gt;-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.... 13759487us : async_getcompleted before spin_lock_irqsave
mtpd-2055    3.... 13759497us!: usbdev_release after kfree(ps): ps=ffffffc0cc042080
&lt;...&gt;-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-&gt;lock.
There should be no issues there that I'm aware of.

commit e6b422b88b46353cf596e0db6dc0e39d50d90d6e upstream.

The following commit cause a regression on ATI chipsets.
'commit e788787ef4f9 ("usb:xhci:Add quirk for Certain
failing HP keyboard on reset after resume")'

This causes pinfo-&gt;smbus_dev to be wrongly set to NULL on
systems with the ATI chipset that this function checks for first.

Added conditional check for AMD chipsets to avoid the overwriting
pinfo-&gt;smbus_dev.

commit a1279ef74eeeb5f627f091c71d80dd7ac766c99d upstream.

Commit e0429362ab15
("usb: Add device quirk for Logitech HD Pro Webcams C920 and C930e")
introduced quirk to workaround an issue with some Logitech webcams.

Apparently model C920-C has the same issue so applying
the same quirk as well.

commit 169e86546f5712179709de23cd64bbb15f199fab upstream.

This commit adds support (an ID, really) for D-Link DWM-157 hardware
version C1 USB modem to option driver.

According to manufacturer-provided Windows INF file the device has four
serial ports:
"D-Link HSPA+DataCard Diagnostics Interface" (interface 2; modem port),
"D-Link HSPA+DataCard NMEA Device" (interface 3),
"D-Link HSPA+DataCard Speech Port" (interface 4),
"D-Link HSPA+DataCard Debug Port" (interface 5).

commit de3af5bf259d7a0bfaac70441c8568ab5998d80c upstream.

Corsair Strafe RGB keyboard has trouble to initialize:

[ 1.679455] usb 3-6: new full-speed USB device number 4 using xhci_hcd
[ 6.871136] usb 3-6: unable to read config index 0 descriptor/all
[ 6.871138] usb 3-6: can't read configurations, error -110
[ 6.991019] usb 3-6: new full-speed USB device number 5 using xhci_hcd
[ 12.246642] usb 3-6: unable to read config index 0 descriptor/all
[ 12.246644] usb 3-6: can't read configurations, error -110
[ 12.366555] usb 3-6: new full-speed USB device number 6 using xhci_hcd
[ 17.622145] usb 3-6: unable to read config index 0 descriptor/all
[ 17.622147] usb 3-6: can't read configurations, error -110
[ 17.742093] usb 3-6: new full-speed USB device number 7 using xhci_hcd
[ 22.997715] usb 3-6: unable to read config index 0 descriptor/all
[ 22.997716] usb 3-6: can't read configurations, error -110

Although it may work after several times unpluging/pluging:

[ 68.195240] usb 3-6: new full-speed USB device number 11 using xhci_hcd
[ 68.337459] usb 3-6: New USB device found, idVendor=1b1c, idProduct=1b20
[ 68.337463] usb 3-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 68.337466] usb 3-6: Product: Corsair STRAFE RGB Gaming Keyboard
[ 68.337468] usb 3-6: Manufacturer: Corsair
[ 68.337470] usb 3-6: SerialNumber: 0F013021AEB8046755A93ED3F5001941

Tried three quirks: USB_QUIRK_DELAY_INIT, USB_QUIRK_NO_LPM and
USB_QUIRK_DEVICE_QUALIFIER, user confirmed that USB_QUIRK_DELAY_INIT alone
can workaround this issue. Hence add the quirk for Corsair Strafe RGB.

<title>usb:xhci:Add quirk for Certain failing HP keyboard on reset after resume</title>

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.

<title>usb: quirks: Add no-lpm quirk for Moshi USB to Ethernet Adapter</title>

commit 7496cfe5431f21da5d27a8388c326397e3f0a5db upstream.

Moshi USB to Ethernet Adapter internally uses a Genesys Logic hub to
connect to Realtek r8153.

The Realtek r8153 ethernet does not work on the internal hub, no-lpm quirk
can make it work.

Since another r8153 dongle at my hand does not have the issue, so add
the quirk to the Genesys Logic hub instead.
