commit 5aed5b7c2430ce318a8e62f752f181e66f0d1053 upstream.

Endpoints are normally deleted from the bandwidth list when they are
dropped, before the virt device is freed.

If xHC host is dying or being removed then the endpoints aren't dropped
cleanly due to functions returning early to avoid interacting with a
non-accessible host controller.

So check and delete endpoints that are still on the bandwidth list when
freeing the virt device.

Solves a list_del corruption kernel crash when unbinding xhci-pci,
caused by xhci_mem_cleanup() when it later tried to delete already freed
endpoints from the bandwidth list.

This only affects hosts that use software bandwidth checking, which
currenty is only the xHC in intel Panther Point PCH (Ivy Bridge)

commit 4f547472380136718b56064ea5689a61e135f904 upstream.

This appears to fix the error:
"xhci_hcd &lt;address&gt;; ERROR Transfer event TRB DMA ptr not part of
current TD ep_index 2 comp_code 13" that appear spuriously (or pretty
often) when using a r8152 USB3 ethernet adapter with integrated hub.

ASM1042 reports as a 0.96 controller, but appears to behave more like 1.0

commit fb8f60dd1b67520e0e0d7978ef17d015690acfc1 upstream.

When port is connected and then disconnected, the state stays as
configured. Which is incorrect as the port is no longer configured,
but in a not attached state.

commit 308c316d16cbad99bb834767382baa693ac42169 upstream.

The gadget driver may have a certain expectation of how the request
completion flow should be from to its configuration. Make sure the
controller driver respect that. That is, don't set IMI (Interrupt on
Missed Isoc) when usb_request-&gt;no_interrupt is set. Also, the driver
should only set IMI to the last TRB of a chain.

commit f78961f8380b940e0cfc7e549336c21a2ad44f4d upstream.

When servicing a transfer completion event, the dwc3 driver will reclaim
TRBs of started requests up to the request associated with the interrupt
event. Currently we don't check for interrupt due to missed isoc, and
the driver may attempt to reclaim TRBs beyond the associated event. This
causes invalid memory access when the hardware still owns the TRB. If
there's a missed isoc TRB with IMI (interrupt on missed isoc), make sure
to stop servicing further.

Note that only the last TRB of chained TRBs has its status updated with
missed isoc.

commit fc4ade55c617dc73c7e9756b57f3230b4ff24540 upstream.

NVIDIA Jetson devices in Force Recovery mode (RCM) do not support
suspending, ie. flashing fails if the device has been suspended. The
devices are still visible in lsusb and seem to work otherwise, making
the issue hard to debug. This has been discovered in various forum
posts, eg. [1].

The patch has been tested on NVIDIA Jetson AGX Xavier, but I'm adding
all the Jetson models listed in [2] on the assumption that they all
behave similarly.

[ Upstream commit bce2b0539933e485d22d6f6f076c0fcd6f185c4c ]

In idmouse_create_image, if any ftip_command fails, it will
go to the reset label. However, this leads to the data in
bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check
for valid image incurs an uninitialized dereference.

Fix this by moving the check before reset label since this
check only be valid if the data after bulk_in_buffer[HEADER]
has concrete data.

Note that this is found by KMSAN, so only kernel compilation
is tested.

<title>Revert "usb: storage: Add quirk for Samsung Fit flash"</title>

<content type='text'>
[ Upstream commit ad5dbfc123e6ffbbde194e2a4603323e09f741ee ]

This reverts commit 86d92f5465958752481269348d474414dccb1552,
which fix the timeout issue for "Samsung Fit Flash".

But the commit affects not only "Samsung Fit Flash" but also other usb
storages that use the same controller and causes severe performance
regression.

 # hdparm -t /dev/sda (without the quirk)
 Timing buffered disk reads: 622 MB in  3.01 seconds = 206.66 MB/sec

 # hdparm -t /dev/sda (with the quirk)
 Timing buffered disk reads: 220 MB in  3.00 seconds =  73.32 MB/sec

The commit author mentioned that "Issue was reproduced after device has
bad block", so this quirk should be applied when we have the timeout
issue with a device that has bad blocks.

We revert the commit so that we apply this quirk by adding kernel
paramters using a bootloader or other ways when we really need it,
without the performance regression with devices that don't have the
issue.

 Timing buffered disk reads: 220 MB in  3.00 seconds =  73.32 MB/sec

The commit author mentioned that "Issue was reproduced after device has
bad block", so this quirk should be applied when we have the timeout
issue with a device that has bad blocks.

We revert the commit so that we apply this quirk by adding kernel
paramters using a bootloader or other ways when we really need it,
without the performance regression with devices that don't have the
issue.

[ Upstream commit eea4c860c3b366369eff0489d94ee4f0571d467d ]

The usb function device call musb_gadget_queue() adds the passed
request to musb_ep::req_list,If the (request-&gt;length &gt; musb_ep-&gt;packet_sz)
and (is_buffer_mapped(req) return false),the rxstate() will copy all data
in fifo to request-&gt;buf which may cause request-&gt;buf out of bounds.

Fix it by add the length check :
fifocnt = min_t(unsigned, request-&gt;length - request-&gt;actual, fifocnt);

[ Upstream commit 7e271f42a5cc3768cd2622b929ba66859ae21f97 ]

xhci_alloc_stream_info() allocates stream context array for stream_info
-&gt;stream_ctx_array with xhci_alloc_stream_ctx(). When some error occurs,
stream_info-&gt;stream_ctx_array is not released, which will lead to a
memory leak.

We can fix it by releasing the stream_info-&gt;stream_ctx_array with
xhci_free_stream_ctx() on the error path to avoid the potential memory
leak.
