commit 1e0d4e6225996f05271de1ebcb1a7c9381af0b27 upstream.

get_device(shost-&gt;shost_gendev.parent) is called after host state has
switched to SHOST_RUNNING. scsi_host_dev_release() shouldn't release the
parent device if host state is still SHOST_CREATED.

commit 66a834d092930cf41d809c0e989b13cd6f9ca006 upstream.

After device is initialized via device_initialize(), or its name is set via
dev_set_name(), the device has to be freed via put_device().  Otherwise
device name will be leaked because it is allocated dynamically in
dev_set_name().

Fix the leak by replacing kfree() with put_device(). Since
scsi_host_dev_release() properly handles IDA and kthread removal, remove
special-casing these from the error handling as well.

commit 032e288097a553db5653af552dd8035cd2a0ba96 upstream.

usb_assign_descriptors() is called with 5 parameters,
the last 4 of which are the usb_descriptor_header for:
  full-speed (USB1.1 - 12Mbps [including USB1.0 low-speed @ 1.5Mbps),
  high-speed (USB2.0 - 480Mbps),
  super-speed (USB3.0 - 5Gbps),
  super-speed-plus (USB3.1 - 10Gbps).

The differences between full/high/super-speed descriptors are usually
substantial (due to changes in the maximum usb block size from 64 to 512
to 1024 bytes and other differences in the specs), while the difference
between 5 and 10Gbps descriptors may be as little as nothing
(in many cases the same tuning is simply good enough).

However if a gadget driver calls usb_assign_descriptors() with
a NULL descriptor for super-speed-plus and is then used on a max 10gbps
configuration, the kernel will crash with a null pointer dereference,
when a 10gbps capable device port + cable + host port combination shows up.
(This wouldn't happen if the gadget max-speed was set to 5gbps, but
it of course defaults to the maximum, and there's no real reason to
artificially limit it)

The fix is to simply use the 5gbps descriptor as the 10gbps descriptor,
if a 10gbps descriptor wasn't provided.

Obviously this won't fix the problem if the 5gbps descriptor is also
NULL, but such cases can't be so trivially solved (and any such gadgets
are unlikely to be used with USB3 ports any way).

commit 90c4d05780d47e14a50e11a7f17373104cd47d25 upstream.

This avoids a null pointer dereference in
f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm}
by simply reusing the 5gbps config for 10gbps.

The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.

Fix the three requests which erroneously used usb_rcvctrlpipe().

commit d00889080ab60051627dab1d85831cd9db750e2a upstream.

There is no validation of the index from dwc3_wIndex_to_dep() and we might
be referring a non-existing ep and trigger a NULL pointer exception. In
certain configurations we might use fewer eps and the index might wrongly
indicate a larger ep index than existing.

By adding this validation from the patch we can actually report a wrong
index back to the caller.

In our usecase we are using a composite device on an older kernel, but
upstream might use this fix also. Unfortunately, I cannot describe the
hardware for others to reproduce the issue as it is a proprietary
implementation.

[  190.544755] configfs-gadget gadget: notify speed -44967296

This is because 4250000000 - 2**32 is -44967296.
