Enable Super speed plus in configfs to support USB3.1 Gen2.
This ensures that when a USB gadget is plugged in, it is
enumerated as Gen 2 and connected at 10 Gbps if the host and
cable are capable of it.
Many in-tree gadget functions (fs, midi, acm, ncm, mass_storage,
etc.) already have SuperSpeed Plus support.

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 device>" > UDC # fails
start adbd
echo "<udc device>" > UDC # now succeeds, but...
# bind order is
# "ADB", mass_storage, ncm

The pullup does not need to be enabled at below situations:
- For platforms which the hardware pullup starts after setting
register even they do not see the VBUS. If the pullup is always
enabled for these platforms, it will consume more power and
break the USB IF compliance tests [1].
- For platforms which need to do BC 1.2 charger detection after
seeing the VBUS. Pullup D+ will break the charger detection
flow.
- For platforms which the system suspend is allowed when the
connection with host is there but the bus is not at suspend.
For these platforms, it is better to disable pullup when
entering the system suspend otherwise the host may confuse
the device behavior after controller is in low power mode.
Disable pullup is considered as a disconnection event from
host side.

Section 7.2.1 of the USB specification requires that no device

a device may only draw (sink) current. They may not provide power
to the pull-up resistor on D+/D- unless VBUS is present (see

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.

First of all the commit e0082698b6 ("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.

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
operation. Note we'll still preserve the attempts counter in case if the
DWC USB3 controller has got some internals delays.

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.

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 = 1
IOM 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.

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.

Since commit 36e2c7421f ("fs: don't allow splice read/write without
explicit ops") we've required that file operation structures explicitly
enable splice support, rather than falling back to the default handlers.
Most /proc files use the indirect 'struct proc_ops' to describe their
file operations, and were fixed up to support splice earlier in commits
40be821d627c..b24c30c67863, but the mountinfo files interact with the
VFS directly using their own 'struct file_operations' and got missed as
a result.
This adds the necessary support for splice to work for /proc/*/mountinfo
and friends.

Commit b9ac0f9dc8 ("PCI: dwc: Move dw_pcie_setup_rc() to DWC common

In non-working case (next-20201211):

0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)

0005:03:00.0 USB controller: PLX Technology, Inc. Device 3380 (rev ab)
The problem seems to be dw_pcie_setup_rc() is now called twice before and
after the link up handling. The fix is to move Tegra's link up handling to
.start_link() function like other DWC drivers. Tegra is a bit more
complicated than others as it re-inits the whole DWC controller to retry
the link. With this, the initialization ordering is restored to match the
prior sequence.

clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.
This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.
So just initialize 'val' to zero to avoid the issue.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
