PTN5110 has an issue on start drp toggling begins with Rp
if the remote end always provides VBUS and presents Rp too,
possibly it can't generate CC change events after detection,
workaround it by starting drp toggling begins with Rd.Change-Id: I6e554d7c7b089cbd38531cea0929e0279a8bfa4d

This patch allows the administrator to configure the interface
name of a function using u_ether (e.g., eem, ncm, rndis).Currently, all such interfaces, regardless of function type, are
always called usb0, usb1, etc. This makes it very cumbersome to
use more than one such type at a time, because userspace cannnot
easily tell the interfaces apart and apply the right
configuration to each one. Interface renaming in userspace based
on driver doesn't help, because the interfaces all have the same
driver. Without this patch, doing this require hacks/workarounds
such as setting fixed MAC addresses on the functions, and then
renaming by MAC address, or scraping configfs after each
interface is created to find out what it is.Setting the interface name is done by writing to the same
"ifname" configfs attribute that reports the interface name after
the function is bound. The write must contain an interface
pattern such as "usb%d" (which will cause the net core to pick
the next available interface name starting with "usb").
This patch does not allow writing an exact interface name (as
opposed to a pattern) because if the interface already exists at
bind time, the bind will fail and the whole gadget will fail to
activate. This could be allowed in a future patch.For compatibility with current userspace, when reading an ifname
that has not currently been set, the result is still "(unnamed
net_device)". Once a write to ifname happens, then reading ifname
will return whatever was last written.Tested by configuring an rndis function and an ncm function on
the same gadget, and writing "rndis%d" to ifname on the rndis
function and "ncm%d" to ifname on the ncm function. When the
gadget was bound, the rndis interface was rndis0 and the ncm
interface was ncm0.Signed-off-by: Lorenzo Colitti

UCSI already conveys the information about a port's connection
status, whether it is operating in UFP or DFP mode, and whether the
partner supports USB data or not. This information can be used to
notify a dual-role controller to start up its host or peripheral
mode accordingly. Add optional support for this by querying each
port's fwnode to look for an associated USB role switch device.
If present, call usb_role_switch_set() with the determined data
role upon Connect Change or Connector Partner Change updates.Bug: 177215430

commit 6cd0fe91387917be48e91385a572a69dfac2f3f7 upstream.
When binding the ConfigFS gadget to a UDC, the functions in each
configuration are added in list order. However, if usb_add_function()
fails, the failed function is put back on its configuration's
func_list and purge_configs_funcs() is called to further clean up.purge_configs_funcs() iterates over the configurations and functions
in forward order, calling unbind() on each of the previously added
functions. But after doing so, each function gets moved to the
tail of the configuration's func_list. This results in reshuffling
the original order of the functions within a configuration such
that the failed function now appears first even though it may have
originally appeared in the middle or even end of the list. At this
point if the ConfigFS gadget is attempted to re-bind to the UDC,
the functions will be added in a different order than intended,
with the only recourse being to remove and relink the functions all
over again.An example of this as follows:
ln -s functions/mass_storage.0 configs/c.1
ln -s functions/ncm.0 configs/c.1
ln -s functions/ffs.adb configs/c.1 # oops, forgot to start adbd
echo "" > UDC # fails
start adbd
echo "" > UDC # now succeeds, but...
# bind order is

There is a spinlock lockup as part of composite_disconnect

This is because the usb_gadget_deactivate is called from
usb_function_deactivate with the same spinlock held.This would result in the below call stack and leads to stall.

commit c318840fb2a42ce25febc95c4c19357acf1ae5ca upstream.
The dummy-hcd driver was written under the assumption that all the
parameters in URBs sent to its root hub would be valid. With URBs
sent from userspace via usbfs, that assumption can be violated.In particular, the driver doesn't fully check the port-feature values
stored in the wValue entry of Clear-Port-Feature and Set-Port-Feature
requests. Values that are too large can cause the driver to perform
an invalid left shift of more than 32 bits. Ironically, two of those
left shifts are unnecessary, because they implement Set-Port-Feature
requests that hubs are not required to support, according to section
11.24.2.13 of the USB-2.0 spec.This patch adds the appropriate checks for the port feature selector
values and removes the unnecessary feature settings. It also rejects
requests to set the TEST feature or to set or clear the INDICATOR and
C_OVERCURRENT features, as none of these are relevant to dummy-hcd's
root-hub emulation.CC:

commit 5d5323a6f3625f101dbfa94ba3ef7706cce38760 upstream.
The commit 0472bf06c6fd ("xhci: Prevent U1/U2 link pm states if exit
latency is too long") was constraining the xhci code not to allow U1/U2
sleep states if the latency to wake up from the U-states reached the
service interval of an periodic endpoint. This fix was not taking into
account that in case the quirk XHCI_INTEL_HOST is set, the wakeup time
will be calculated and configured differently.It checks for u1_params.mel/u2_params.mel as a limit. But the code could
decide to write another MEL into the hardware. This leads to broken
cases where not enough bandwidth is available for other devices:usb 1-2: can't set config #1, error -28
This patch is fixing that case by checking for timeout_ns after the
wakeup time was calculated depending on the quirks.Fixes: 0472bf06c6fd ("xhci: Prevent U1/U2 link pm states if exit latency is too long")

commit e5f4ca3fce90a37b23a77bfcc86800d484a80514 upstream.
First of all the commit e0082698b689 ("usb: dwc3: ulpi: conditionally
resume ULPI PHY") introduced the Suspend USB2.0 HS/FS/LS PHY regression,
as by design of the fix any attempt to read/write from/to the PHY control
registers will completely disable the PHY suspension, which consequently
will increase the USB bus power consumption. Secondly the fix won't work
well for the very first attempt of the ULPI PHY control registers IO,
because after disabling the USB2.0 PHY suspension functionality it will
still take some time for the bus to resume from the sleep state if one has
been reached before it. So the very first PHY register read/write
operation will take more time than the busy-loop provides and the IO
timeout error might be returned anyway.Here we suggest to fix the denoted problems in the following way. First of
all let's not disable the Suspend USB2.0 HS/FS/LS PHY functionality so to
make the controller and the USB2.0 bus more power efficient. Secondly
instead of that we'll extend the PHY IO op wait procedure with 1 - 1.2 ms
sleep if the PHY suspension is enabled (1ms should be enough as by LPM
specification it is at most how long it takes for the USB2.0 bus to resume
from L1 (Sleep) state). Finally in case if the USB2.0 PHY suspension
functionality has been disabled on the DWC USB3 controller setup procedure
we'll compensate the USB bus resume process latency by extending the
busy-loop attempts counter.Fixes: e0082698b689 ("usb: dwc3: ulpi: conditionally resume ULPI PHY")

commit fca3f138105727c3a22edda32d02f91ce1bf11c9 upstream.
Originally the procedure of the ULPI transaction finish detection has been
developed as a simple busy-loop with just decrementing counter and no
delays. It's wrong since on different systems the loop will take a
different time to complete. So if the system bus and CPU are fast enough
to overtake the ULPI bus and the companion PHY reaction, then we'll get to
take a false timeout error. Fix this by converting the busy-loop procedure
to take the standard bus speed, address value and the registers access
mode into account for the busy-loop delay calculation.Here is the way the fix works. It's known that the ULPI bus is clocked
with 60MHz signal. In accordance with [1] the ULPI bus protocol is created
so to spend 5 and 6 clock periods for immediate register write and read
operations respectively, and 6 and 7 clock periods - for the extended
register writes and reads. Based on that we can easily pre-calculate the
time which will be needed for the controller to perform a requested IO

commit ce722da66d3e9384aa2de9d33d584ee154e5e157 upstream.
In accordance with [1] the DWC_usb3 core sets the GUSB2PHYACCn.VStsDone
bit when the PHY vendor control access is done and clears it when the
application initiates a new transaction. The doc doesn't say anything
about the GUSB2PHYACCn.VStsBsy flag serving for the same purpose. Moreover
we've discovered that the VStsBsy flag can be cleared before the VStsDone
bit. So using the former as a signal of the PHY control registers
completion might be dangerous. Let's have the VStsDone flag utilized
instead then.[1] Synopsys DesignWare Cores SuperSpeed USB 3.0 xHCI Host Controller

If an active transfer is dequeued, then the endpoint is freed to start a
new transfer. Make sure to clear the endpoint's transfer wait flag for
this case.Fixes: e0d19563eb6c ("usb: dwc3: gadget: Wait for transfer completion")

usb_gadget_deactivate/usb_gadget_activate does not execute the UDC start
operation, which may leave EP0 disabled and event IRQs disabled when
re-activating the function. Move the enabling/disabling of USB EP0 and
device event IRQs to be performed in the pullup routine.Fixes: ae7e86108b12 ("usb: dwc3: Stop active transfers before halting the controller")

commit 0f041b8592daaaea46e91a8ebb3b47e6e0171fd8 upstream.
Warm reboot scenarios some times type C Mux driver gets Mux configuration
request as HPD=1,IRQ=1. In that scenario typeC Mux driver need to configure
Mux as follows as per IOM requirement:
(1). Confgiure Mux HPD = 1, IRQ = 0
(2). Configure Mux with HPD = 1, IRQ = 1IOM expects TypeC Mux configuration as follows:
(1). HPD=1, IRQ=0
(2). HPD=1, IRQ=1
if IOM gets mux config request (2) without configuring (1), it will ignore
the request. The impact of this is there is no DP_alt mode display.Fixes: 43d596e32276 ("usb: typec: intel_pmc_mux: Check the port status before connect")

commit 5e5ff0b4b6bcb4d17b7a26ec8bcfc7dd4651684f upstream.
syzbot is reporting UAF at usb_submit_urb() [1], for
service_outstanding_interrupt() is not checking WDM_DISCONNECTING
before calling usb_submit_urb(). Close the race by doing same checks
wdm_read() does upon retry.Also, while wdm_read() checks WDM_DISCONNECTING with desc->rlock held,
service_interrupt_work() does not hold desc->rlock. Thus, it is possible
that usb_submit_urb() is called from service_outstanding_interrupt() from
service_interrupt_work() after WDM_DISCONNECTING was set and kill_urbs()
from wdm_disconnect() completed. Thus, move kill_urbs() in
wdm_disconnect() to after cancel_work_sync() (which makes sure that
service_interrupt_work() is no longer running) completed.Although it seems to be safe to dereference desc->intf->dev in
service_outstanding_interrupt() even if WDM_DISCONNECTING was already set
because desc->rlock or cancel_work_sync() prevents wdm_disconnect() from
reaching list_del() before service_outstanding_interrupt() completes,
let's not emit error message if WDM_DISCONNECTING is set by
wdm_disconnect() while usb_submit_urb() is in progress.[1] https://syzkaller.appspot.com/bug?extid=9e04e2df4a32fb661daf
