USB: Add reset-resume quirk for two Plantronics usb headphones.

2015-10-22T21:37:52+00:00

commit 8484bf2981b3d006426ac052a3642c9ce1d8d980 upstream.

These two headphones need a reset-resume quirk to properly resume to

usb: Add device quirk for Logitech PTZ cameras

2015-10-22T21:37:52+00:00

commit 72194739f54607bbf8cfded159627a2015381557 upstream.

Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
ConferenceCam CC3000e Camera.
This fixes the failed camera enumeration on some boot, particularly on
machines with fast CPU.

Tested by connecting a Logitech PTZ Pro Camera to a machine with a
Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
while recording the kernel logs and taking camera picture after each boot.
Before the patch, more than 7% of the boots show some enumeration transfer
failures and in a few of them, the kernel is giving up before actually
enumerating the webcam. After the patch, the enumeration has been correct
on every reboot.

usb: Use the USB_SS_MULT() macro to get the burst multiplier.

2015-10-22T21:37:52+00:00

commit ff30cbc8da425754e8ab96904db1d295bd034f27 upstream.

Bits 1:0 of the bmAttributes are used for the burst multiplier.
The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7
into use.

Use the existing USB_SS_MULT() macro instead to make sure the mult value
and hence max packet calculations are correct for USB3.1 devices.

Note that burst multiplier in bmAttributes is zero based and that
the USB_SS_MULT() macro adds one.

usb: xhci: Add support for URB_ZERO_PACKET to bulk/sg transfers

2015-10-22T21:37:51+00:00

commit 4758dcd19a7d9ba9610b38fecb93f65f56f86346 upstream.

This commit checks for the URB_ZERO_PACKET flag and creates an extra
zero-length td if the urb transfer length is a multiple of the endpoint's
max packet length.

xhci: change xhci 1.0 only restrictions to support xhci 1.1

2015-10-22T21:37:51+00:00

commit dca7794539eff04b786fb6907186989e5eaaa9c2 upstream.

Some changes between xhci 0.96 and xhci 1.0 specifications forced us to
check the hci version in code, some of these checks were implemented as
hci_version == 1.0, which will not work with new xhci 1.1 controllers.

xhci 1.1 behaves similar to xhci 1.0 in these cases, so change these
checks to hci_version >= 1.0

usb: xhci: Clear XHCI_STATE_DYING on start

2015-10-22T21:37:51+00:00

commit e5bfeab0ad515b4f6df39fe716603e9dc6d3dfd0 upstream.

For whatever reason if XHCI died in the previous instant
then it will never recover on the next xhci_start unless we
clear the DYING flag.

USB: whiteheat: fix potential null-deref at probe

2015-10-22T21:37:51+00:00

commit cbb4be652d374f64661137756b8f357a1827d6a4 upstream.

Fix potential null-pointer dereference at probe by making sure that the
required endpoints are present.

The whiteheat driver assumes there are at least five pairs of bulk
endpoints, of which the final pair is used for the "command port". An
attempt to bind to an interface with fewer bulk endpoints would
currently lead to an oops.

Fixes CVE-2015-5257.

usb: host: ehci-sys: delete useless bus_to_hcd conversion

2015-09-21T17:00:08+00:00

commit 0521cfd06e1ebcd575e7ae36aab068b38df23850 upstream.

The ehci platform device's drvdata is the pointer of struct usb_hcd
already, so we doesn't need to call bus_to_hcd conversion again.

usb: dwc3: ep0: Fix mem corruption on OUT transfers of more than 512 bytes

2015-09-21T17:00:07+00:00

commit b2fb5b1a0f50d3ebc12342c8d8dead245e9c9d4e upstream.

DWC3 uses bounce buffer to handle non max packet aligned OUT transfers and
the size of bounce buffer is 512 bytes. However if the host initiates OUT
transfers of size more than 512 bytes (and non max packet aligned), the
driver throws a WARN dump but still programs the TRB to receive more than
512 bytes. This will cause bounce buffer to overflow and corrupt the
adjacent memory locations which can be fatal.

Fix it by programming the TRB to receive a maximum of DWC3_EP0_BOUNCE_SIZE
(512) bytes.
