commit 05c8f1b67e67dcd786ae3fe44492bbc617b4bd12 upstream.
These drive enclosures have firmware bugs that make it impossible to mount
a new virtual ISO image after Linux ejects the old one if the device is
locked by Linux. Windows bypasses this problem by the fact that they do
not lock the device. Add a quirk to disable device locking for these
drive enclosures.

commit 21b5fcdccb32ff09b6b63d4a83c037150665a83f upstream.
musb_gadget_queue() adds the passed request to musb_ep::req_list. If the
endpoint is idle and it is the first request then it invokes
musb_queue_resume_work(). If the function returns an error then the
error is passed to the caller without any clean-up and the request
remains enqueued on the list. If the caller enqueues the request again
then the list corrupts.
Remove the request from the list on error.

commit c2115b2b16421d93d4993f3fe4c520e91d6fe801 upstream.
Commit 7c75bde329d7 ("usb: musb: musb_dsps: request_irq() after
initializing musb") has inverted the calls to
dsps_setup_optional_vbus_irq() and dsps_create_musb_pdev() without
updating correctly the error path. dsps_create_musb_pdev() allocates and
registers a new platform device which must be unregistered and freed
with platform_device_unregister(), and this is missing upon
dsps_setup_optional_vbus_irq() error.
While on the master branch it seems not to trigger any issue, I observed
a kernel crash because of a NULL pointer dereference with a v5.10.70
stable kernel where the patch mentioned above was backported. With this
kernel version, -EPROBE_DEFER is returned the first time
dsps_setup_optional_vbus_irq() is called which triggers the probe to
error out without unregistering the platform device. Unfortunately, on
the Beagle Bone Black Wireless, the platform device still living in the
system is being used by the USB Ethernet gadget driver, which during the
boot phase triggers the crash.
My limited knowledge of the musb world prevents me to revert this commit
which was sent to silence a robot warning which, as far as I understand,
does not make sense. The goal of this patch was to prevent an IRQ to
fire before the platform device being registered. I think this cannot
ever happen due to the fact that enabling the interrupts is done by the
->enable() callback of the platform musb device, and this platform
device must be already registered in order for the core or any other
user to use this callback.
Hence, I decided to fix the error path, which might prevent future
errors on mainline kernels while also fixing older ones.

commit ff0e50d3564f33b7f4b35cadeabd951d66cfc570 upstream.
The command ring pointer is located at [6:63] bits of the command
ring control register (CRCR). All the control bits like command stop,
abort are located at [0:3] bits. While aborting a command, we read the
CRCR and set the abort bit and write to the CRCR. The read will always
give command ring pointer as all zeros. So we essentially write only
the control bits. Since we split the 64 bit write into two 32 bit writes,
there is a possibility of xHC command ring stopped before the upper
dword (all zeros) is written. If that happens, xHC updates the upper
dword of its internal command ring pointer with all zeros. Next time,
when the command ring is restarted, we see xHC memory access failures.
Fix this issue by only writing to the lower dword of CRCR where all
control bits are located.

commit 65a205e6113506e69a503b61d97efec43fc10fd7 upstream.
A recent change that started reporting break events to the line
discipline caused the tty-buffer insertions to no longer be serialised
by inserting events also from the completion handler for the interrupt
endpoint.
Completion calls for distinct endpoints are not guaranteed to be
serialised. For example, in case a host-controller driver uses
bottom-half completion, the interrupt and bulk-in completion handlers
can end up running in parallel on two CPUs (high-and low-prio tasklets,
respectively) thereby breaking the tty layer's single producer
assumption.
Fix this by holding the read lock also when inserting characters from
the bulk endpoint.

commit 8253a34bfae3278baca52fc1209b7c29270486ca upstream.
When passing 'phys' in the devicetree to describe the USB PHY phandle
(which is the recommended way according to
Documentation/devicetree/bindings/usb/ci-hdrc-usb2.txt) the
following NULL pointer dereference is observed on i.MX7 and i.MX8MM:

This happens because the charger functions check for the phy presence
inside the imx_usbmisc_data structure (data->usb_phy), but the chipidea
core populates the usb_phy passed via 'phys' inside 'struct ci_hdrc'
(ci->usb_phy) instead.
This causes the NULL pointer dereference inside imx7d_charger_detection().
Fix it by also searching for 'phys' in case 'fsl,usbphy' is not found.

commit c32dfec6c1c36bbbcd5d33e949d99aeb215877ec upstream.
Some CP2102 do not support event-insertion mode but return no error when
attempting to enable it.
This means that any event escape characters in the input stream will not
be escaped by the device and consequently regular data may be
interpreted as escape sequences and be removed from the stream by the
driver.
The reporter's device has batch number DCL00X etched into it and as
discovered by the SHA2017 Badge team, counterfeit devices with that
marking can be detected by sending malformed vendor requests. [1][2]
Tests confirm that the possibly counterfeit CP2102 returns a single byte
in response to a malformed two-byte part-number request, while an
original CP2102 returns two bytes. Assume that every CP2102 that behaves
this way also does not support event-insertion mode (e.g. cannot report
parity errors).

commit 91fac0741d4817945c6ee0a17591421e7f5ecb86 upstream.
If the driver runs out of minor numbers it would release minor 0 and
allow another device to claim the minor while still in use.
Fortunately, registering the tty class device of the second device would
fail (with a stack dump) due to the sysfs name collision so no memory is
leaked.

Add US_FL_BULK_IGNORE_TAG to fix it. Also update my e-mail address.
2.6c is the only firmware that claims Linux compatibility.

commit 91bb163e1e4f88092f50dfaa5a816b658753e4b2 upstream.
According USB spec each ISOC transaction should be performed in a
designated for that transaction interval. On bus errors or delays
in operating system scheduling of client software can result in no
packet being transferred for a (micro)frame. An error indication
should be returned as status to the client software in such a case.
Current implementation in case of missed/dropped interval send same
data in next possible interval instead of reporting missed isoc.
This fix complete requests with -ENODATA if interval elapsed.
HSOTG core in BDMA and Slave modes haven't HW support for
(micro)frames tracking, this is why SW should care about tracking
of (micro)frames. Because of that method and consider operating
system scheduling delays, added few additional checking's of elapsed
target (micro)frame:
1. Immediately before enabling EP to start transfer.
2. With any transfer completion interrupt.
3. With incomplete isoc in/out interrupt.
4. With EP disabled interrupt because of incomplete transfer.
5. With OUT token received while EP disabled interrupt (for OUT
transfers).
6. With NAK replied to IN token interrupt (for IN transfers).
As part of ISOC flow, additionally fixed 'current' and 'target' frame
calculation functions. In HS mode SOF limits provided by DSTS register
is 0x3fff, but in non HS mode this limit is 0x7ff.
Tested by internal tool which also using for dwc3 testing.

commit 17956b53ebff6a490baf580a836cbd3eae94892b upstream.
This loop is supposed to loop until if reads something other than
CS_IDST or until it times out after 30,000 attempts. But because of
the || vs && bug, it will never time out and instead it will loop a
minimum of 30,000 times.
This bug is quite old but the code is only used in USB_DEVICE_TEST_MODE
so it probably doesn't affect regular usage.

[ Upstream commit 66cce9e73ec61967ed1f97f30cee79bd9a2bb7ee ]
When a remote usb device is attached to the local Virtual USB
Host Controller Root Hub port, the bound device driver may send
a port reset command.
vhci_hcd accepts port resets only when the device doesn't have
port address assigned to it. When reset happens device is in
assigned/used state and vhci_hcd rejects it leaving the port in
a stuck state.
This problem was found when a blue-tooth or xbox wireless dongle
was passed through using usbip.
A few drivers reset the port during probe including mt76 driver
specific to this bug report. Fix the problem with a change to
honor reset requests when device is in used state (VDEV_ST_USED).

This reverts commit 5d5323a6f3625f101dbfa94ba3ef7706cce38760.
That commit effectively disabled Intel host initiated U1/U2 lpm for devices
with periodic endpoints.
Before that commit we disabled host initiated U1/U2 lpm if the exit latency
was larger than any periodic endpoint service interval, this is according
to xhci spec xhci 1.1 specification section 4.23.5.2
After that commit we incorrectly checked that service interval was smaller
than U1/U2 inactivity timeout. This is not relevant, and can't happen for
Intel hosts as previously set U1/U2 timeout = 105% * service interval.
Patch claimed it solved cases where devices can't be enumerated because of
bandwidth issues. This might be true but it's a side effect of accidentally
turning off lpm.
exit latency calculations have been revised since then

[ Upstream commit bcacbf06c891374e7fdd7b72d11cda03b0269b43 ]
Currently the composite driver encodes the MaxPower field of
the configuration descriptor by reading the c->MaxPower of the
usb_configuration only if it is non-zero, otherwise it falls back
to using the value hard-coded in CONFIG_USB_GADGET_VBUS_DRAW.
However, there are cases when a configuration must explicitly set
bMaxPower to 0, particularly if its bmAttributes also has the
Self-Powered bit set, which is a valid combination.
This is specifically called out in the USB PD specification section
9.1, in which a PDUSB device "shall report zero in the bMaxPower
field after negotiating a mutually agreeable Contract", and also
verified by the USB Type-C Functional Test TD.4.10.2 Sink Power
Precedence Test.
The fix allows the c->MaxPower to be used for encoding the bMaxPower
even if it is 0, if the self-powered bit is also set. An example
usage of this would be for a ConfigFS gadget to be dynamically
updated by userspace when the Type-C connection is determined to be
operating in Power Delivery mode.

f_ncm tx timeout can call us with null skb to flush
a pending frame. In this case skb is NULL to begin
with but ceases to be null after dev->wrap() completes.
In such a case in->maxpacket will be read, even though
we've failed to check that 'in' is not NULL.
Though I've never observed this fail in practice,
however the 'flush operation' simply does not make sense with
a null usb IN endpoint - there's nowhere to flush to...
(note that we're the gadget/device, and IN is from the point
of view of the host, so here IN actually means outbound...)
