USB: quirks: Add USB_QUIRK_IGNORE_REMOTE_WAKEUP quirk for BYD zhaoxin notebook

2020-09-23T10:40:43+00:00

commit bcea6dafeeef7d1a6a8320a249aabf981d63b881 upstream.

Add a USB_QUIRK_IGNORE_REMOTE_WAKEUP quirk for the BYD zhaoxin notebook.
This notebook come with usb touchpad. And we would like to disable
touchpad wakeup on this notebook by default.

usb: Fix out of sync data toggle if a configured device is reconfigured

2020-09-17T11:47:56+00:00

commit cfd54fa83a5068b61b7eb28d3c117d8354c74c7a upstream.

Userspace drivers that use a SetConfiguration() request to "lightweight"
reset an already configured usb device might cause data toggles to get out
of sync between the device and host, and the device becomes unusable.

The xHCI host requires endpoints to be dropped and added back to reset the
toggle. If USB core notices the new configuration is the same as the
current active configuration it will avoid these extra steps by calling
usb_reset_configuration() instead of usb_set_configuration().

A SetConfiguration() request will reset the device side data toggles.
Make sure usb_reset_configuration() function also drops and adds back the
endpoints to ensure data toggles are in sync.

To avoid code duplication split the current usb_disable_device() function
and reuse the endpoint specific part.

usb: core: fix slab-out-of-bounds Read in read_descriptors

2020-09-17T11:47:55+00:00

commit a18cd6c9b6bc73dc17e8b7e9bd07decaa8833c97 upstream.

The USB device descriptor may get changed between two consecutive
enumerations on the same device for some reason, such as DFU or
malicius device.
In that case, we may access the changing descriptor if we don't take
the device lock here.

USB: quirks: Ignore duplicate endpoint on Sound Devices MixPre-D

2020-09-03T09:27:07+00:00

commit 068834a2773b6a12805105cfadbb3d4229fc6e0a upstream.

The Sound Devices MixPre-D audio card suffers from the same defect
as the Sound Devices USBPre2: an endpoint shared between a normal
audio interface and a vendor-specific interface, in violation of the
USB spec.  Since the USB core now treats duplicated endpoints as bugs
and ignores them, the audio endpoint isn't available and the card
can't be used for audio capture.

Along the same lines as commit bdd1b147b802 ("USB: quirks: blacklist
duplicate ep on Sound Devices USBPre2"), this patch adds a quirks
entry saying to ignore ep5in for interface 1, leaving it available for
use with standard audio interface 2.

usb: core: fix quirks_param_set() writing to a const pointer

2020-08-19T06:16:14+00:00

[ Upstream commit b1b6bed3b5036509b449b5965285d5057ba42527 ]

The function quirks_param_set() takes as argument a const char* pointer
to the new value of the usbcore.quirks parameter. It then casts this
pointer to a non-const char* pointer and passes it to the strsep()
function, which overwrites the value.

Fix this by creating a copy of the value using kstrdup() and letting
that copy be written to by strsep().

USB: core: Fix misleading driver bug report

2020-05-27T15:46:34+00:00

[ Upstream commit ac854131d9844f79e2fdcef67a7707227538d78a ]

The syzbot fuzzer found a race between URB submission to endpoint 0
and device reset.  Namely, during the reset we call usb_ep0_reinit()
because the characteristics of ep0 may have changed (if the reset
follows a firmware update, for example).  While usb_ep0_reinit() is
running there is a brief period during which the pointers stored in
udev->ep_in[0] and udev->ep_out[0] are set to NULL, and if an URB is
submitted to ep0 during that period, usb_urb_ep_type_check() will
report it as a driver bug.  In the absence of those pointers, the
routine thinks that the endpoint doesn't exist.  The log message looks
like this:

------------[ cut here ]------------
usb 2-1: BOGUS urb xfer, pipe 2 != type 2
WARNING: CPU: 0 PID: 9241 at drivers/usb/core/urb.c:478
usb_submit_urb+0x1188/0x1460 drivers/usb/core/urb.c:478

Now, although submitting an URB while the device is being reset is a
questionable thing to do, it shouldn't count as a driver bug as severe
as submitting an URB for an endpoint that doesn't exist.  Indeed,
endpoint 0 always exists, even while the device is in its unconfigured
state.

To prevent these misleading driver bug reports, this patch updates
usb_disable_endpoint() to avoid clearing the ep_in[] and ep_out[]
pointers when the endpoint being disabled is ep0.  There's no danger
of leaving a stale pointer in place, because the usb_host_endpoint
structure being pointed to is stored permanently in udev->ep0; it
doesn't get deallocated until the entire usb_device structure does.

usb: core: hub: limit HUB_QUIRK_DISABLE_AUTOSUSPEND to USB5534B

2020-05-20T06:20:31+00:00

commit 76e1ef1d81a4129d7e2fb8c48c83b166d1c8e040 upstream.

The problem described in v5.6 commit 1208f9e1d758c9 ("USB: hub: Fix the
broken detection of USB3 device in SMSC hub") applies solely to the
USB5534B hub [2] present on the Kingfisher Infotainment Carrier Board,
manufactured by Shimafuji Electric Inc [3].

Despite that, the aforementioned commit applied the quirk to _all_ hubs
carrying vendor ID 0x424 (i.e. SMSC), of which there are more [4] than
initially expected. Consequently, the quirk is now enabled on platforms
carrying SMSC/Microchip hub models which potentially don't exhibit the
original issue.

To avoid reports like [1], further limit the quirk's scope to
USB5534B [2], by employing both Vendor and Product ID checks.

Tested on H3ULCB + Kingfisher rev. M05.

USB: usbfs: fix mmap dma mismatch

2020-05-20T06:20:30+00:00

commit a0e710a7def471b8eb779ff551fc27701da49599 upstream.

In commit 2bef9aed6f0e ("usb: usbfs: correct kernel->user page attribute
mismatch") we switched from always calling remap_pfn_range() to call
dma_mmap_coherent() to handle issues with systems with non-coherent USB host
controller drivers.  Unfortunatly, as syzbot quickly told us, not all the world
is host controllers with DMA support, so we need to check what host controller
we are attempting to talk to before doing this type of allocation.

Thanks to Christoph for the quick idea of how to fix this.
