commit 02a6982b0ccfcdc39e20016f5fc9a1b7826a6ee7 upstream.

The check whether the TRB ring is full or empty in dwc3_calc_trbs_left()
is insufficient. It assumes there are active TRBs if there's any request
in the started_list. However, that's not the case for requests with a
large SG list.

That is, if we have a single usb request that requires more TRBs than
the total TRBs in the TRB ring, the queued TRBs will be available when
all the TRBs in the ring are completed. But the request is only
partially completed and remains in the started_list. With the current
logic, the TRB ring is empty, but dwc3_calc_trbs_left() returns 0.

Fix this by additionally checking for the request-&gt;num_trbs for active
TRB count.

<title>Revert "usb: gadget: composite: fix OS descriptors w_value logic"</title>

<id>cae6f388b229b8eca1a445a7f077b2ae87f9ca1d</id>
<content type='text'>
commit 51cdd69d6a857f527d6d0697a2e1f0fa8bca1005 upstream.

This reverts commit ec6ce7075ef879b91a8710829016005dc8170f17.

Fix installation of WinUSB driver using OS descriptors. Without the
fix the drivers are not installed correctly and the property
'DeviceInterfaceGUID' is missing on host side.

The original change was based on the assumption that the interface
number is in the high byte of wValue but it is in the low byte,
instead. Unfortunately, the fix is based on MS documentation which is
also wrong.

The actual USB request for OS descriptors (using USB analyzer) looks
like:

Offset  0   1   2   3   4   5   6   7
0x000   C1  A1  02  00  05  00  0A  00

C1: bmRequestType (device to host, vendor, interface)
A1: nas magic number
0002: wValue (2: nas interface)
0005: wIndex (5: get extended property i.e. nas interface GUID)
008E: wLength (142)

The fix was tested on Windows 10 and Windows 11.

commit 40c974826734836402abfd44efbf04f63a2cc1c1 upstream.

If the clock sehci-&gt;clk was not enabled in spear_ehci_hcd_drv_probe,
it should not be disabled in any path.

Conversely, if it was enabled in spear_ehci_hcd_drv_probe, it must be disabled
in all error paths to ensure proper cleanup.

[Analysis]
The first is AA lock, it because wrong logic, it need a unlock.
The second is AB lock, it needs to rearrange the order of lock usage.

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(chaoskey_list_lock);
                               lock(minor_rwsem);
                               lock(chaoskey_list_lock);
  lock(minor_rwsem);

 *** DEADLOCK ***
[Analysis]
The first is AA lock, it because wrong logic, it need a unlock.
The second is AB lock, it needs to rearrange the order of lock usage.

[ Upstream commit 422dc0a4d12d0b80dd3aab3fe5943f665ba8f041 ]

chaoskey_open() takes the lock only to increase the
counter of openings. That means that the mutual exclusion
with chaoskey_disconnect() cannot prevent an increase
of the counter and chaoskey_open() returning a success.

If that race is hit, chaoskey_disconnect() will happily
free all resources associated with the device after
it has dropped the lock, as it has read the counter
as zero.

To prevent this race chaoskey_open() has to check
the presence of the device under the lock.
However, the current per device lock cannot be used,
because it is a part of the data structure to be
freed. Hence an additional global mutex is needed.
The issue is as old as the driver.

<title>usb: using mutex lock and supporting O_NONBLOCK flag in iowarrior_read()</title>

[ Upstream commit 44feafbaa66ec86232b123bb8437a6a262442025 ]

iowarrior_read() uses the iowarrior dev structure, but does not use any
lock on the structure. This can cause various bugs including data-races,
so it is more appropriate to use a mutex lock to safely protect the
iowarrior dev structure. When using a mutex lock, you should split the
branch to prevent blocking when the O_NONBLOCK flag is set.

In addition, it is unnecessary to check for NULL on the iowarrior dev
structure obtained by reading file-&gt;private_data. Therefore, it is
better to remove the check.

commit 37bb5628379295c1254c113a407cab03a0f4d0b4 upstream.

The "dev_dbg(&amp;urb-&gt;dev-&gt;dev, ..." which happens after usb_free_urb(urb)
is a use after free of the "urb" pointer.  Store the "dev" pointer at the
start of the function to avoid this issue.
