commit f259ca3eed6e4b79ac3d5c5c9fb259fb46e86217 upstream.
Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer or accessing memory beyond the endpoint array should a
malicious device lack the expected endpoints.
Note that the endpoint access that causes the NULL-deref is currently
only used for debugging purposes during probe so the oops only happens
when dynamic debugging is enabled. This means the driver could be
rewritten to continue to accept device with only two endpoints, should
such devices exist.

commit b7321e81fc369abe353cf094d4f0dc2fe11ab95f upstream.
Make sure to check for the required interrupt-in endpoint to avoid
dereferencing a NULL-pointer should a malicious device lack such an

Note that a fairly recent change purported to fix this issue, but added
an insufficient test on the number of endpoints only, a test which can

commit 2fae9e5a7babada041e2e161699ade2447a01989 upstream.
This patch fixes a NULL pointer dereference caused by a race codition in
the probe function of the legousbtower driver. It re-structures the
probe function to only register the interface after successfully reading
the board's firmware ID.
The probe function does not deregister the usb interface after an error
receiving the devices firmware ID. The device file registered
(/dev/usb/legousbtower%d) may be read/written globally before the probe
function returns. When tower_delete is called in the probe function
(after an r/w has been initiated), core dev structures are deleted while
the file operation functions are still running. If the 0 address is
mappable on the machine, this vulnerability can be used to create a
Local Priviege Escalation exploit via a write-what-where condition by
remapping dev->interrupt_out_buffer in tower_write. A forged USB device
and local program execution would be required for LPE. The USB device
would have to delay the control message in tower_probe and accept
the control urb in tower_open whilst guest code initiated a write to the
device file as tower_delete is called from the error in tower_probe.
This bug has existed since 2003. Patch tested by emulated device.

commit 539587511835ea12d8daa444cbed766cf2bc3612 upstream.
In sg_timeout(), req->status is set to "-ETIMEDOUT" before calling
into usb_sg_cancel(). usb_sg_cancel() will do nothing and return
directly if req->status has been set to a non-zero value. This will
cause driver hang whenever transfer time out is triggered.
This patch fixes this issue. It could be backported to stable kernel
with version later than v3.15.

commit 4ec0ef3a82125efc36173062a50624550a900ae0 upstream.
The iowarrior driver expects at least one valid endpoint. If given
malicious descriptors that specify 0 for the number of endpoints,
it will crash in the probe function. Ensure there is at least
one endpoint on the interface before using it.

usb: patches for v4.4 merge window
This pull request is large with a total of 136 non-merge
commits. Because of its size, we will only describe the big things in
broad terms.
Many will be happy to know that dwc3 is now almost twice as fast after
some profiling and speed improvements. Also in dwc3, John Youn from
Synopsys added support for their new DWC USB3.1 IP Core and the HAPS
platform which can be used to validate it.
A series of patches from Robert Baldyga cleaned up uses of
ep->driver_data as a flag for "claimed endpoint" in favor of the new
ep->claimed flag.
Sudip Mukherjee fixed a ton of really old problems on the amd5536udc
driver. That should make a few people happy.
Heikki Krogerus worked on converting dwc3 to the unified device property
interface.
Together with these, there's a ton of non-critical fixes, typos and
stuff like that.

The bulk queue tests are used to show 'best performance' for bulk
transfer, we are often asked this question by users. The implementation
is the same with iso test, that is queue request at interrupt completion,
so we reuse the iso structures, and rename them as common one.
It's result should be very close to IC simulation, in order
to get that, the device side should also need to prepare enough
queue.
We have got the 'best performance' (IN: 41MB, OUT: 39MB) at i.mx platform
(USB2, ARM Cortex A9, stream mode need to enable) with below command:
Host side:
modprobe usbtest
./testusb -a -t 27 -g 64 -s 16384
./testusb -a -t 28 -g 64 -s 16384
Gadget side:
modprobe g_zero loopdefault=1 qlen=64 buflen=16384

These are simple non-queued interrupt IN and interrupt OUT transfers. Currently,
only gadget zero is capable of executing the interrupt EP test cases. However,
extending the same to other gadgets is extremely simple and can be done
on-demand.
The two new tests added are
- Test 25: To verify Interrupt OUT transfer
- Test 26: To verify Interrupt IN transfer
Since the default value of wMaxPacketSize is set as 1024, so interrupt
IN transfers must be specified with the size parameter = multiple of
1024. Otherwise the default value (512) in the usbtest application fails
the transfer. See [RUN 4] for sample logs
The application logs (usbtest) and corresponding kernel logs are as
following:
[Run 1]
./testusb -a -c 10 -s 2048 -t 26 -v 511
usbtest 7-1:3.0: TEST 26: read 2048 bytes 10 times
[Run 2]
./testusb -a -c 10 -s 1024 -t 25 -v 511
usbtest 7-1:3.0: TEST 25: write 1024 bytes 10 times
[Run 3]
./testusb -a -c 10 -s 1098 -t 25 -v 511
usbtest 7-1:3.0: TEST 25: write 1098 bytes 10 times
[Run 4 - Failure case scenario]
./testusb -a -t 26
unknown speed /dev/bus/usb/007/004 0
/dev/bus/usb/007/004 test 26 --> 75 (Value too large for defined data type)
usbtest 7-1:3.0: TEST 26: read 512 bytes 1000 times
usb 7-1: test26 failed, iterations left 999, status -75 (not 0)

I have a j5 create (JUA210) USB 2 video device and adding it device id
to SIS USB video gets it to work.
