commit fd7cd061adcf5f7503515ba52b6a724642a839c8 upstream.
We received several reports of systems rebooting and powering on
after an attempted shutdown. Testing showed that setting
XHCI_SPURIOUS_WAKEUP quirk in addition to the XHCI_SPURIOUS_REBOOT
quirk allowed the system to shutdown as expected for LynxPoint-LP
xHCI controllers. Set the quirk back.
Note that the quirk was originally introduced for LynxPoint and
LynxPoint-LP just for this same reason. See:
commit 638298dc66ea ("xhci: Fix spurious wakeups after S5 on Haswell")
It was later limited to only concern HP machines as it caused
regression on some machines, see both bug and commit:
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=66171
commit 6962d914f317 ("xhci: Limit the spurious wakeup fix only to HP machines")
Later it was discovered that the powering on after shutdown
was limited to LynxPoint-LP (Haswell-ULT) and that some non-LP HP
machine suffered from spontaneous resume from S3 (which should
not be related to the SPURIOUS_WAKEUP quirk at all). An attempt
to fix this then removed the SPURIOUS_WAKEUP flag usage completely.
commit b45abacde3d5 ("xhci: no switching back on non-ULT Haswell")
Current understanding is that LynxPoint-LP (Haswell ULT) machines
need the SPURIOUS_WAKEUP quirk, otherwise they will restart, and
plain Lynxpoint (Haswell) machines may _not_ have the quirk
set otherwise they again will restart.

commit 3b4739b8951d650becbcd855d7d6f18ac98a9a85 upstream.
If a host fails to wake up a isochronous SuperSpeed device from U1/U2
in time for a isoch transfer it will generate a "No ping response error"
Host will then move to the next transfer descriptor.
Handle this case in the same way as missed service errors, tag the
current TD as skipped and handle it on the next transfer event.

commit 72194739f54607bbf8cfded159627a2015381557 upstream.
Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
ConferenceCam CC3000e Camera.
This fixes the failed camera enumeration on some boot, particularly on
machines with fast CPU.
Tested by connecting a Logitech PTZ Pro Camera to a machine with a
Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
while recording the kernel logs and taking camera picture after each boot.
Before the patch, more than 7% of the boots show some enumeration transfer
failures and in a few of them, the kernel is giving up before actually
enumerating the webcam. After the patch, the enumeration has been correct
on every reboot.

commit b0a688ddcc5015eb26000c63841db7c46cfb380a upstream.
since commit 33c300cb90a6 ("usb: musb: dsps:
don't fake of_node to musb core") we have been
preventing CPPI 4.1 from probing due to NULL
of_node. We can't revert said commit otherwise
a different regression would show up, so the fix
is to look for the parent device's (glue layer's)
of_node instead, since that's the thing which
is actually described in DTS.

commit 762982db33b23029e98c844611e2e8beeb75bc0d upstream.
The gpio-desc migration done in v4.0 caused a regression
with legacy boots due to reversed reset logic.
e.g. omap3-beagle USB host breaks on legacy boot.
Request the reset GPIO with GPIOF_ACTIVE_LOW flag so that
it matches the driver logic and pin behaviour.

commit ff30cbc8da425754e8ab96904db1d295bd034f27 upstream.
Bits 1:0 of the bmAttributes are used for the burst multiplier.
The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7
into use.
Use the existing USB_SS_MULT() macro instead to make sure the mult value
and hence max packet calculations are correct for USB3.1 devices.
Note that burst multiplier in bmAttributes is zero based and that
the USB_SS_MULT() macro adds one.

commit 56ffa1d154c7e12af16273f0cdc42690dd05caf5 upstream.
According to spec, there are functional and protocol stalls.
For functional stall, it is for bulk and interrupt endpoints,
below are cases for it:
- Host sends SET_FEATURE request for Set-Halt, the udc driver
needs to set stall, and return true unconditionally.
- The gadget driver may call usb_ep_set_halt to stall certain
endpoints, if there is a transfer in pending, the udc driver
should not set stall, and return -EAGAIN accordingly.
These two kinds of stall need to be cleared by host using CLEAR_FEATURE
request (Clear-Halt).
For protocol stall, it is for control endpoint, this stall will
be set if the control request has failed. This stall will be
cleared by next setup request (hardware will do it).
It fixed usbtest (drivers/usb/misc/usbtest.c) Test 13 "set/clear halt"
test failure, meanwhile, this change has been verified by
USB2 CV Compliance Test and MSC Tests.

Don't check if timer is running with a timer_pending() before
deleting it with del_timer_sync(), this defies the whole point of

commit dca7794539eff04b786fb6907186989e5eaaa9c2 upstream.
Some changes between xhci 0.96 and xhci 1.0 specifications forced us to
check the hci version in code, some of these checks were implemented as
hci_version == 1.0, which will not work with new xhci 1.1 controllers.
xhci 1.1 behaves similar to xhci 1.0 in these cases, so change these
checks to hci_version >= 1.0

During quick plug/removal of OTG adapter during dual-role testing

commit 913e4a90b6f9687ac0f543e7b632753e4f51c441 upstream.
According to USB Audio Device 2.0 Spec, Ch4.10.1.1:
wMaxPacketSize is defined as follows:
Maximum packet size this endpoint is capable of sending or receiving
when this configuration is selected.
This is determined by the audio bandwidth constraints of the endpoint.
In current code, the wMaxPacketSize is defined as the maximum packet size
for ISO endpoint, and it will let the host reserve much more space than
it really needs, so that we can't let more endpoints work together at
one frame.
We find this issue when we try to let 4 f_uac2 gadgets work together [1]
at FS connection.

commit b2fb5b1a0f50d3ebc12342c8d8dead245e9c9d4e upstream.
DWC3 uses bounce buffer to handle non max packet aligned OUT transfers and
the size of bounce buffer is 512 bytes. However if the host initiates OUT
transfers of size more than 512 bytes (and non max packet aligned), the
driver throws a WARN dump but still programs the TRB to receive more than
512 bytes. This will cause bounce buffer to overflow and corrupt the
adjacent memory locations which can be fatal.
Fix it by programming the TRB to receive a maximum of DWC3_EP0_BOUNCE_SIZE
(512) bytes.

commit 49bda21266fdf195142e8b5dea057f09e96ada9f upstream.
This commit fixes the following issues:
1. The 9th bit of buf was believed to be the LSB of divisor's
exponent, but the hardware interprets it as MSB (9th bit) of the
mantissa. The exponent is actually one bit shorter and applies
to base 4, not 2 as previously believed.
2. Loop iterations doubled the exponent instead of incrementing.
3. The exponent wasn't checked for overflow.
4. The function returned requested rate instead of actual rate.
Due to issue #2, the old code deviated from the wrong formula
described in #1 and actually yielded correct rates when divisor
was lower than 4096 by using exponents of 0, 2 or 4 base-2,
interpreted as 0, 1, 2 base-4 with the 9th mantissa bit clear.
However, at 93.75 kbaud or less the rate turned out too slow
due to #2 or too fast due to #2 and #3.
I tested this patch by sending and validating 0x00,0x01,..,0xff
to an FTDI dongle at 234, 987, 2401, 9601, 31415, 115199, 250k,
500k, 750k, 1M, 1.5M, 3M+1 baud. All rates passed.
I also used pv to check speed at some rates unsupported by FTDI:
45 (the lowest possible), 2M, 4M, 5M and 6M-1. Looked sane.

commit 951d3793bbfc0a441d791d820183aa3085c83ea9 upstream.
The driver used usb_get_serial_data(port->serial) which compiled but resulted
in a NULL pointer being returned (and subsequently used). I did not go deeper
into this but I guess this is a regression.

commit 653cdc13a340ad1cef29f1bab0d05d0771fa1d57 upstream.
Tests with a Sierra Wireless MC7355 have shown that 1199:9041 devices
also require the option_send_setup() code to be used on the USB
interface for the AT port to make unsolicited response codes work
correctly. Move these devices from the qcserial driver to the option
driver like it has been done for the 1199:68c0 devices in commit
d80c0d14183516f184a5ac88e11008ee4c7d2a2e ("USB: qcserial/option: make
AT URCs work for Sierra Wireless MC73xx").

commit c41b7767673cb76adeb2b5fde220209f717ea13c upstream.
The p_interval should be less if the 'bInterval' at the descriptor
is larger, eg, if 'bInterval' is 5 for HS, the p_interval should be
8000 / 16 = 500.
It fixes the patch 9bb87f168931 ("usb: gadget: f_uac2: send
reasonably sized packets")

commit 2f01a33bd26545c16fea7592697f7f15c416402b upstream.
The ehci_init_driver is used to initialize hcd APIs for each
ehci controller driver, it is designed to be called only one time
and before driver register is called. The current design will
cause ehci_init_driver is called multiple times at probe process,
it will cause hc_driver's initialization affect current running hcd.
We run out NULL pointer dereference problem when one hcd is started
by module_init, and the other is started by otg thread at SMP platform.
The reason for this problem is ehci_init_driver will do memory copy
for current uniform hc_driver, and this memory copy will do memset (as 0)
first, so when the first hcd is running usb_add_hcd, and the second
hcd may clear the uniform hc_driver's space (at ehci_init_driver),
then the first hcd will meet NULL pointer at the same time.
See below two logs:

commit c93e64e91248becd0edb8f01723dff9da890e2ab upstream.
This patch fixes a bug in the error pathway of
usb_add_gadget_udc_release() in udc-core.c. If the udc registration
fails, the gadget registration is not fully undone; there's a
put_device(&gadget->dev) call but no device_del().

commit 74472233233f577eaa0ca6d6e17d9017b6e53150 upstream.
Add support for the Sierra Wireless AR8550 device with
USB descriptor 0x1199, 0x68AB.
It is common with MC879x modules 1199:683c/683d which
also are composite devices with 7 interfaces (0..6)
and also MDM62xx based as the AR8550.
The major difference are only the interface attributes
02/02/01 on interfaces 3 and 4 on the AR8550. They are
vendor specific ff/ff/ff on MC879x modules.

commit ffe5adcb7661d94e952d6b5ed7f493cb4ef0c7bc upstream.
When xhci_mem_cleanup() is called, it's possible that the command
timer isn't initialized and scheduled. For those cases, to delete
the command timer causes soft-lockup as below stack dump shows.
The patch avoids deleting the command timer if it's not scheduled
with the help of timer_pending().

commit 7895086afde2a05fa24a0e410d8e6b75ca7c8fdd upstream.
We need to check that a TRB is part of the current segment
before calculating its DMA address.
Previously a ring segment didn't use a full memory page, and every
new ring segment got a new memory page, so the off by one
error in checking the upper bound was never seen.
Now that we use a full memory page, 256 TRBs (4096 bytes), the off by one
didn't catch the case when a TRB was the first element of the next segment.
This is triggered if the virtual memory pages for a ring segment are
next to each in increasing order where the ring buffer wraps around and
causes errors like:
[ 106.398223] xhci_hcd 0000:00:14.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 0 comp_code 1
[ 106.398230] xhci_hcd 0000:00:14.0: Looking for event-dma fffd3000 trb-start fffd4fd0 trb-end fffd5000 seg-start fffd4000 seg-end fffd4ff0
The trb-end address is one outside the end-seg address.

Port link change with port in resume state should not be
reported to usbcore, as this is an internal state to be
handled by xhci driver. Reporting PLC to usbcore may
cause usbcore clearing PLC first and port change event irq

commit fac4271d1126c45ceaceb7f4a336317b771eb121 upstream.
When the link is just waken, it's in Resume state, and driver sets PLS to
U0. This refers to Phase 1. Phase 2 refers to when the link has completed
the transition from Resume state to U0.
With the fix of xhci: report U3 when link is in resume state, it also
exposes an issue that usb3 roothub and controller can suspend right
after phase 1, and this causes a hard hang in controller.
To fix the issue, we need to prevent usb3 bus suspend if any port is
resuming in phase 1.

commit 243292a2ad3dc365849b820a64868927168894ac upstream.
xhci_hub_report_usb3_link_state() returns pls as U0 when the link
is in resume state, and this causes usb core to think the link is in
U0 while actually it's in resume state. When usb core transfers
control request on the link, it fails with TRB error as the link
is not ready for transfer.
To fix the issue, report U3 when the link is in resume state, thus
usb core knows the link it's not ready for transfer.

commit 326124a027abc9a7f43f72dc94f6f0f7a55b02b3 upstream.
When resetting a device the number of active TTs may need to be
corrected by xhci_update_tt_active_eps, but the number of old active
endpoints supplied to it was always zero, so the number of TTs and the
bandwidth reserved for them was not updated, and could rise
unnecessarily.
This affected systems using Intel's Patherpoint chipset, which rely on
software bandwidth checking. For example, a Lenovo X230 would lose the
ability to use ports on the docking station after enough suspend/resume
cycles because the bandwidth calculated would rise with every cycle when
a suitable device is attached.
The correct number of active endpoints is calculated in the same way as
in xhci_reserve_bandwidth.

commit 5fb2c782f451a4fb9c19c076e2c442839faf0f76 upstream.
This device automatically switches itself to another mode (0x1405)
unless the specific access pattern of Windows is followed in its
initial mode. That makes a dirty unmount of the internal storage
devices inevitable if they are mounted. So the card reader of
such a device should be ignored, lest an unclean removal become
inevitable.
This replaces an earlier patch that ignored all LUNs of this device.
That patch was overly broad.

commit 3496810663922617d4b706ef2780c279252ddd6a upstream.
virt_dev->num_cached_rings counts on freed ring and is not updated
correctly. In xhci_free_or_cache_endpoint_ring() function, the free ring
is added into cache and then num_rings_cache is incremented as below:
virt_dev->ring_cache[rings_cached] =
virt_dev->eps[ep_index].ring;
virt_dev->num_rings_cached++;
here, free ring pointer is added to a current index and then
index is incremented.
So current index always points to empty location in the ring cache.
For getting available free ring, current index should be decremented
first and then corresponding ring buffer value should be taken from ring
cache.
But In function xhci_endpoint_init(), the num_rings_cached index is
accessed before decrement.
virt_dev->eps[ep_index].new_ring =
virt_dev->ring_cache[virt_dev->num_rings_cached];
virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL;
virt_dev->num_rings_cached--;
This is bug in manipulating the index of ring cache.
And it should be as below:
virt_dev->num_rings_cached--;
virt_dev->eps[ep_index].new_ring =
virt_dev->ring_cache[virt_dev->num_rings_cached];
virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL;

commit 2d2a316765d956bc5cb6bb367b2ec52ca59ab8e9 upstream.
Commit 25cd2882e2fc ("usb/xhci: Change how we indicate a host supports
Link PM.") removed the code to set lpm_capable for USB 3.0 super-speed
root hub. The intention of that change was to avoid touching usb core
internal field, a.k.a. lpm_capable, and let usb core to set it by
checking U1 and U2 exit latency values in the descriptor.
Usb core checks and sets lpm_capable in hub_port_init(). Unfortunately,
root hub is a special usb device as it has no parent. Hub_port_init()
will never be called for a root hub device. That means lpm_capable will
by no means be set for the root hub. As the result, lpm isn't functional
at all in Linux kernel.
This patch add the code to check and set lpm_capable when registering a
root hub device. It could be back-ported to kernels as old as v3.15,
that contains the Commit 25cd2882e2fc ("usb/xhci: Change how we indicate
a host supports Link PM.").

commit 7d8021c967648accd1b78e5e1ddaad655cd2c61f upstream.
This patch fixes a bug introduced by commit 977dcfdc6031 ("USB: OHCI:
don't lose track of EDs when a controller dies"). The commit changed
ed_state from ED_UNLINK to ED_IDLE too early, before finish_urb() had
been called. The user-visible consequence is that the driver
occasionally crashes or locks up when an URB is submitted while
another URB for the same endpoint is being unlinked.
This patch moves the ED state change later, to the right place. The
drawback is that now we may unnecessarily execute some instructions
multiple times when a controller dies. Since controllers dying is an
exceptional occurrence, a little wasted time won't matter.

commit be9d39881fc4fa39a64b6eed6bab5d9ee5125344 upstream.
Currently, we're calling musb_start() twice for DRD ports
in some situations. This has been observed to cause enumeration
issues after suspend/resume cycles with AM335x.
In order to fix the problem, we just have to fix the check
on musb_has_gadget() so that it only returns true if
current mode is Host and ignore the fact that we have or
not a gadget driver loaded.
Fixes: ae44df2e21b5 (usb: musb: call musb_start() only once in OTG mode)

commit 8515bac01a983d277148e4fcc5f235bf603de577 upstream.
Mass storage function created via configfs always reports eight LUNs
to the hosts even if only one LUN has been configured. Adjust the
number when the USB function is allocated based on LUNs that user
has created.
