When reading synchronously from a non-zero endpoint, gadgetfs will
return -EFAULT even if the read succeeds, due to a bad check of the
copy_to_iter() return value.
This fix compares the return value of copy_to_iter to the amount of
bytes that was passed, and only fails if they are not the same.

For case 14 and case 21, their correct return value is the number
of bytes transferred, so it is a positive integer. But in usbtest_ioctl,
it takes non-zero as false return value for usbtest_do_ioctl, so
it will treat the correct test as wrong test, then the time on
tests will be the minus value.

There may be a race condition if f_fs calls unregister_gadget_item in

This patch fixes an issue that isochronous transfer's data is possible to
be lost as a workaround. Since this driver uses a workqueue to start
the dmac, the transfer is possible to be delayed when system load is high.

This patch fixes an issue that unexpected BRDY interruption happens
when the usb_ep_{enable,disable}() are called with different direction.
In this case, the driver will cause the following message:
renesas_usbhs e6590000.usb: irq_ready run_error 1 : -16
This issue causes the followings:
1) A pipe is enabled as transmission
2) The pipe sent a data
3) The pipe is disabled and re-enabled as reception.
4) The pipe got a queue
Since the driver doesn't clear the BRDYSTS flags after 2) above, the issue
happens. If we add such clearing the flags into the driver, the code will
become complicate. So, this patch clears the BRDYSTS flag of reception in
usbhsg_ep_enable() to avoid complicate.

DWC3 has one interesting peculiarity with chained
transfers. If we setup N chained transfers and we
get a short packet before processing all N TRBs,
DWC3 will (conditionally) issue a XferComplete or
XferInProgress event and retire all TRBs from the
one which got a short packet to the last without
clearing their HWO bits.
This means SW must clear HWO bit manually, which
this patch is doing.

Hans de Goede has reported a difficulty in the Linux port of libusb.
When a device is removed, the poll() system call in usbfs starts
returning POLLERR as soon as udev->state is set to
USB_STATE_NOTATTACHED, but the outstanding URBs are not available for
reaping until some time later (after usbdev_remove() has been called).
This is awkward for libusb or other usbfs clients, although not an
insuperable problem.
At any rate, it's easy to change usbfs so that it returns POLLHUP as
soon as the state becomes USB_STATE_NOTATTACHED but it doesn't return
POLLERR until after the outstanding URBs have completed. That's what
this patch does; it uses the fact that ps->list is always on the
dev->filelist list until usbdev_remove() takes it off, which happens
after all the outstanding URBs have been cancelled.

usbdev_mmap allocates a buffer. The size of the buffer is determined
by a user. So with this code (no need to be root):
int fd = open("/dev/bus/usb/001/001", O_RDONLY);
mmap(NULL, 0x800000, PROT_READ, MAP_SHARED, fd, 0);
we can see a warning:

Allocations like this one should be marked as __GFP_NOWARN. So do so.
The size could be also clipped by something like:
if (size >= (1 << (MAX_ORDER + PAGE_SHIFT - 1)))
return -ENOMEM;
But I think the overall limit of 16M (by usbfs_increase_memory_usage)
is enough, so that we only silence the warning here.

In ehci_turn_off_all_ports() all EHCI port registers are cleared to zero.
On some hardware, this can lead to an system hang,
when ehci_port_power() accesses the already cleared registers.
This patch changes the order of cleanup.
First call ehci_port_power() which respects the current bits in
port status registers
and afterwards cleanup the hard way by setting everything to zero.

This patch fixes fives off-by-one bugs in the ftdi-elan driver code. The
bug can be triggered by plugging a USB adapter for CardBus 3G cards (model
U132 manufactured by Elan Digital Systems, Ltd), causing a kernel panic.
The fix was tested on Ubuntu 14.04.4 with 4.7.0-rc14.2.0-27-generic+ and
4.4.0-22-generic+ kernel. In the ftdi_elan_synchronize function, an
off-by-one memory corruption occurs when packet_bytes is equal or bigger
than m. After having read m bytes, that is bytes_read is equal to m, "
..\x00" is still copied to the stack variable causing an out bounds write
of 4 bytes, which overwrites the stack canary and results in a kernel
panic.
This off-by-one requires physical access to the machine. It is not
exploitable since we have no control on the overwritten data. Similar
off-by-one bugs have been observed in 4 other functions:
ftdi_elan_stuck_waiting, ftdi_elan_read, ftdi_elan_edset_output and
ftdi_elan_flush_input_fifo.

The locking in hub_activate() is not adequate to provide full mutual
exclusion with hub_quiesce(). The subroutine locks the hub's
usb_interface, but the callers of hub_quiesce() (such as
hub_pre_reset() and hub_event()) hold the lock to the hub's
usb_device.
This patch changes hub_activate() to make it acquire the same lock as
those other routines.

The early-exit pathway in hub_activate, added by commit e50293ef9775
("USB: fix invalid memory access in hub_activate()") needs
improvement. It duplicates code that is already present at the end of
the subroutine, and it neglects to undo the effect of a
usb_autopm_get_interface_no_resume() call.
This patch fixes both problems by making the early-exit pathway jump
directly to the end of the subroutine. It simplifies the code at the
end by merging two conditionals that actually test the same condition
although they appear different: If type < HUB_INIT3 then type must be
either HUB_INIT2 or HUB_INIT, and it can't be HUB_INIT because in that
case the subroutine would have exited earlier.

Memory leak and unbalanced reference count:
If the hub gets disconnected while the core is still activating it, this
can result in leaking memory of few USB structures.
This will happen if we have done a kref_get() from hub_activate() and
scheduled a delayed work item for HUB_INIT2/3. Now if hub_disconnect()
gets called before the delayed work expires, then we will cancel the
work from hub_quiesce(), but wouldn't do a kref_put(). And so the
unbalance.
kmemleak reports this as (with the commit e50293ef9775 backported to

Deadlocks:
If the hub gets disconnected early enough (i.e. before INIT2/INIT3 are
finished and the init_work is still queued), the core may call
hub_quiesce() after acquiring interface device locks and it will wait
for the work to be cancelled synchronously. But if the work handler is
already running in parallel, it may try to acquire the same interface
device lock and this may result in deadlock.
Fix both the issues by removing the call to cancel_delayed_work_sync().

phy-sun4i-usb now has proper dr_mode handling, it always registers an
extcon, and sends a notify with the mode (even when in peripheral- /
host-only mode) at least once.
So we can simply the sunxi musb glue by always registering its extcon
notifier and relying on sunxi_musb_work() to enable vbus when in
host-only mode.
This also enables host- and peripheral-only mode with vbus monitoring.
