commit 11fb37998759c48e4e4c200c974593cbeab25d3e upstream.
The current code tries to test for bits that are masked out by
usb_endpoint_maxp(). Instead, use the proper accessor to access
the new high bandwidth bits.

commit cbeef22fd611c4f47c494b821b2b105b8af970bb upstream.
Quoting Hans:
If we return 1 from our post_reset handler, then our disconnect handler
will be called immediately afterwards. Since pre_reset blocks all scsi
requests our disconnect handler will then hang in the scsi_remove_host
call.
This is esp. bad because our disconnect handler hanging for ever also
stops the USB subsys from enumerating any new USB devices, causes commands
like lsusb to hang, etc.
In practice this happens when unplugging some uas devices because the hub
code may see the device as needing a warm-reset and calls usb_reset_device
before seeing the disconnect. In this case uas_configure_endpoints fails
with -ENODEV. We do not want to print an error for this, so this commit
also silences the shost_printk for -ENODEV.
ENDQUOTE
However, if we do that we better drop any unconditional execution
and report to the SCSI subsystem that we have undergone a reset
but we are not operational now.

commit ce5bf9a50daf2d9078b505aca1cea22e88ecb94a upstream.
Upon usb composition switch there is possibility of ep0 file
release happening after gadget driver bind. In case of composition
switch from adb to a non-adb composition gadget will never gets
bound again resulting into failure of usb device enumeration. Fix
this issue by checking FFS_FL_BOUND flag and avoid extra
gadget driver unbind if it is already done as part of composition
switch.
This fixes adb reconnection error reported on Android running
v4.4 and above kernel versions. Verified on Hikey running vanilla
v4.15-rc7 + few out of tree Mali patches.

commit c7b8f77872c73f69a16528a9eb87afefcccdc18b upstream.
According to drivers/usb/serial/io_edgeport.c, the driver may sleep
under a spinlock.
The function call path is:
edge_bulk_in_callback (acquire the spinlock)
process_rcvd_data
process_rcvd_status
change_port_settings
send_iosp_ext_cmd
write_cmd_usb
usb_kill_urb --> may sleep
To fix it, the redundant usb_kill_urb() is removed from the error path
after usb_submit_urb() fails.
This possible bug is found by my static analysis tool (DSAC) and checked
by my code review.

commit 928afc85270753657b5543e052cc270c279a3fe9 upstream.
The UAS mode of Norelsys NS1068(X) is reported to fail to work on
several platforms with the following error message:
xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8

And when trying to mount a partition on the disk the disk will
disconnect from the USB controller, then after re-connecting the device
will be offlined and not working at all.
Falling back to USB mass storage can solve this problem, so ignore UAS

commit 7ae2c3c280db183ca9ada2675c34ec2f7378abfa upstream.
The error-handling pathways in usb_add_gadget_udc_release() are messed
up. Aside from the uninformative statement labels, they can deallocate
the udc structure after calling put_device(), which is a double-free.
This was observed by KASAN in automatic testing.
This patch cleans up the routine. It preserves the requirement that
when any failure occurs, we call put_device(&gadget->dev).

Automated tests triggered this by opening usbmon and accessing the
mmap while simultaneously resizing the buffers. This bug was with
us since 2006, because typically applications only size the buffers
once and thus avoid racing. Reported by Kirill A. Shutemov.

commit b8626f1dc29d3eee444bfaa92146ec7b291ef41c upstream.
When using a GPIO which is high by default, and initialize the
driver in USB Hub mode, initialization fails with:
[ 111.757794] usb3503 0-0008: SP_ILOCK failed (-5)
The reason seems to be that the chip is not properly reset.
Probe does initialize reset low, however some lines later the
code already set it back high, which is not long enouth.
Make sure reset is asserted for at least 100us by inserting a
delay after initializing the reset pin during probe.

commit 07b9f12864d16c3a861aef4817eb1efccbc5d0e6 upstream.
USB 3.1 devices are not detected as 3.1 capable since 4.15-rc3 due to a
off by one in commit 81cf4a45360f ("USB: core: Add type-specific length
check of BOS descriptors")
It uses USB_DT_USB_SSP_CAP_SIZE() to get SSP capability size which takes
the zero based SSAC as argument, not the actual count of sublink speed
attributes.
USB3 spec 9.6.2.5 says "The number of Sublink Speed Attributes = SSAC + 1."
The type-specific length check patch was added to stable and needs to be
fixed there as well

but need sendsetup = true for the NMEA port to make it work properly.
Simplify the patch compared to v1 as suggested by Bjørn Mork by taking
advantage of the fact that existing devices work with sendsetup = true
too.
Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add
DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID
0x9090.

commit bd3486ded7a0c313a6575343e6c2b21d14476645 upstream.
When babble condition happens, the musb controller might automatically
turns off VBUS. On DA8xx platform, the controller generates drvvbus
interrupt for turning off VBUS along with the babble interrupt.
In this case, we should handle the babble interrupt first and recover
from the babble condition.
This change ignores the drvvbus interrupt if babble interrupt is also
generated at the same time, so the babble recovery routine works
properly.

/sys/devices/platform/vhci_hcd/status file (world-readable) and in debug
output when "usbip --debug port" is run.
Fix it to not leak. The socket pointer address is not used at the moment
and it was made visible as a convenient way to find IP address from socket
pointer address by looking up /proc/net/{tcp,tcp6}.
As this opens a security hole, the fix replaces socket pointer address with
sockfd.

commit c6688ef9f29762e65bce325ef4acd6c675806366 upstream.
Harden CMD_SUBMIT path to handle malicious input that could trigger
large memory allocations. Add checks to validate transfer_buffer_length
and number_of_packets to protect against bad input requesting for
unbounded memory allocations. Validate early in get_pipe() and return
failure.

commit 635f545a7e8be7596b9b2b6a43cab6bbd5a88e43 upstream.
get_pipe() routine doesn't validate the input endpoint number
and uses to reference ep_in and ep_out arrays. Invalid endpoint
number can trigger BUG(). Range check the epnum and returning
error instead of calling BUG().
Change caller stub_recv_cmd_submit() to handle the get_pipe()
error return.

commit 48a4ff1c7bb5a32d2e396b03132d20d552c0eca7 upstream.
A malicious USB device with crafted descriptors can cause the kernel
to access unallocated memory by setting the bNumInterfaces value too
high in a configuration descriptor. Although the value is adjusted
during parsing, this adjustment is skipped in one of the error return
paths.
This patch prevents the problem by setting bNumInterfaces to 0
initially. The existing code already sets it to the proper value
after parsing is complete.

commit 62354454625741f0569c2cbe45b2d192f8fd258e upstream.
There is another JMS567-based USB3 UAS enclosure (152d:0578) that fails
with the following error:
[sda] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[sda] tag#0 Sense Key : Illegal Request [current]
[sda] tag#0 Add. Sense: Invalid field in cdb
The issue occurs both with UAS (occasionally) and mass storage
(immediately after mounting a FS on a disk in the enclosure).
Enabling US_FL_BROKEN_FUA quirk solves this issue.
This patch adds an UNUSUAL_DEV with US_FL_BROKEN_FUA for the enclosure
for both UAS and mass storage.

commit a3acc696085e112733d191a77b106e67a4fa110b upstream.
The specification says that the Reserved1 field in OS_DESC_EXT_COMPAT
must have the value "1", but when this feature was first implemented we
rejected any non-zero values.
This was adjusted to accept all non-zero values (while now rejecting
zero) in commit 53642399aa71 ("usb: gadget: f_fs: Fix wrong check on
reserved1 of OS_DESC_EXT_COMPAT"), but that breaks any userspace
programs that worked previously by returning EINVAL when Reserved1 == 0
which was previously the only value that succeeded!
If we just set the field to "1" ourselves, both old and new userspace
programs continue to work correctly and, as a bonus, old programs are
now compliant with the specification without having to fix anything
themselves.

commit a4f0927ef588cf62bb864707261482c874352942 upstream.
Currently UDC core calls ->udc_set_speed() with the speed parameter
containing the maximum speed supported by the gadget function
driver. This might very well be more than that supported by the
UDC controller driver.
Select the lesser of the 2 speeds so both UDC and gadget function
driver are operating within limits.
This fixes PHY Erratic errors and 2 second enumeration delay on
TI's AM437x platforms.

commit 81cf4a45360f70528f1f64ba018d61cb5767249a upstream.
As most of BOS descriptors are longer in length than their header
'struct usb_dev_cap_header', comparing solely with it is not sufficient
to avoid out-of-bounds access to BOS descriptors.
This patch adds descriptor type specific length check in
usb_get_bos_descriptor() to fix the issue.

called before the device has been setup and get real_port initialized.

commit e4ec40ec4b260efcca15089de4285a0a3411259b upstream.
xHC can generate two events for a short transfer if the short TRB and
last TRB in the TD are not the same TRB.
The driver will handle the TD after the first short event, and remove
it from its internal list. Driver then incorrectly prints a warning
for the second event:
"WARN Event TRB for slot x ep y with no TDs queued"
Fix this by not printing a warning if we get a event on a empty list
if the previous event was a short event.
