On x86-64, a 32-bit process (TIF_IA32) can switch to 64-bit mode with
ljmp, and then use the "syscall" instruction to make a 64-bit system
call. A 64-bit process make a 32-bit system call with int $0x80.
In both these cases under CONFIG_SECCOMP=y, secure_computing() will use
the wrong system call number table. The fix is simple: test TS_COMPAT
instead of TIF_IA32. Here is an example exploit:
/* test case for seccomp circumvention on x86-64
There are two failure modes: compile with -m64 or compile with -m32.
The -m64 case is the worst one, because it does "chmod 777 ." (could
be any chmod call). The -m32 case demonstrates it was able to do
stat(), which can glean information but not harm anything directly.
A buggy kernel will let the test do something, print, and exit 1; a
fixed kernel will make it exit with SIGKILL before it does anything.

When resuming from suspend newer Synaptics touchpads do not recover
correctly. Analysis of the resume sequence as applied in Linux was
compared to that of other operating systems. This indicated that the
other OSs were resetting the mouse before attempting to detect it (for
all Synaptics touchpads, old and new). Applying this same modification
fixes these newer Synaptics touchpads and brings the driver into line
with common OS reset behaviour.

Commit ec42d4481e36cbdb5b2801f957e678211a9e5ae2 broke usbtouchscreen for
some eGalax/EETI devices that claim to be HID, but are not.
Devices confirmed to be real HID have the class set to HID and the protocol
set to 'mouse'. Some have HID class but protocol set to 'none'. Those are
not HID and should be driven by usbtouchscreen.
Fix the device ignoring macro by adding match for the protocol too.

handling in xfs_compat_ioctl but never added any compat handler back, so

free_uid() and free_user_ns() are corecursive when CONFIG_USER_SCHED=n,
but free_user_ns() is called from free_uid() by way of uid_hash_remove(),
which requires uidhash_lock to be held. free_user_ns() then calls
free_uid() to complete the destruction.
Fix this by deferring the destruction of the user_namespace.

Feeding 32-bit length cast down to 'u16' to min() to calculate the FIFO
count in musb_host_tx() risks sending a short packet prematurely for
transfer sizes over 64 KB.
Similarly, although data transfer size shouldn't exceed 65535 bytes for
the control endpoint, making musb_h_ep0_continue() more robust WRT URBs
with possibly oversized buffer will not hurt either...

For some strange reason the host side musb_giveback() decides
that it's always got an IN transfer when the hardware endpoint
is using a shared FIFO. This causes musb_save_toggle() to read
the toggle state from the RXCSR register instead of TXCSR, and
may also cause unneeded reloading of RX endpoint registers.

The musb_h_disable() routine can oops in some cases:
- It's not safe to read hep->hcpriv outside musb->lock,
since it gets changed on completion IRQ paths.
- The list iterators aren't safe to use in that way;
just remove the first element while !list_empty(),
so deletions on other code paths can't make trouble.
We need two "scrub the list" loops because only one branch
should touch hardware and advance the schedule.

The urb_dequeue() method forgets to unlink 'struct musb_qh' from the
control or bulk schedules when the URB being cancelled is the only
one queued to its endpoint. That will cause musb_advance_schedule()
to block once it reaches 'struct musb_qh' with now empty URB list, so
URBs queued for other endpoints after the one being dequeued will not
be served.
Fix by unlinking the QH from the list except when it's already being
handled (typically by musb_giveback). Since a QH with an empty URB
list is now supposed to be freed, do that. And remove a now-useless
check from musb_advance_schedule().

The input queue should be used for TX on endpoints which
share FIFO hardware. The host TX path wasn't doing that.
Shared FIFOs are most often configured for periodic endpoints,
which are mostly used for RX/IN transfers ... that's probably
how this bug managed to linger for a long time.

Now that the musb build fixes for DaVinci got merged (RC3?), kick in
the other bits needed to get it finally *working* in mainline:
- Use clk_enable()/clk_disable() ... the "always enable USB clocks"
code this originally relied on has since been removed.
- Initialize the USB device only after the relevant I2C GPIOs are
available, so the host side can properly enable VBUS.
- Tweak init sequencing to cope with mainline's relatively late init
of the I2C system bus for power switches, transceivers, and so on.
Sanity tested on DM6664 EVM for host and peripheral modes; that system
won't boot with CONFIG_PM enabled, so OTG can't yet be tested. Also
verified on OMAP3.
(Unrelated: correct the MODULE_PARM_DESC spelling of musb_debug.)

This patch (as1218) fixes a problem with a radio-control joystick used
in the "walkera 4#3" helicopter. This device responds to the initial
Get-String-Descriptor request for string 0 (which is really the list
of supported languages) by sending its config descriptor! The
usb_get_string() routine needs to check whether it got the right
type of descriptor.
Oddly enough, this sort of check is already present in
usb_get_descriptor(). The patch changes the error code from -EPROTO
to -ENODATA, because -EPROTO shows up in so many other contexts to
indicate a hardware failure rather than a firmware error.

In apollon case, it only used udc, so udc configuration should select
USB_OTG_UTILS also.

This patch (as1220) automatically disables stalls when g_file_storage
finds itself running with an Atmel device controller, because the
Atmel hardware/driver isn't capable of halting bulk endpoints
correctly.

This patch (as1219) adds the IGNORE_RESIDUE flag to the unusual_devs
entries for Genesys Logic's USB-IDE adapter. Although this device
usually gets the residue correct, there is one command crucial to the
operation of CD and DVD drives which it messes up.

The Motorola MOTOMAGX phones (Z6, E8, Zn5 so far) are providing
combined ACM/BLAN USB configuration. Since it has Vendor Specific
class, the corresponding drivers (cdc-acm, zaurus) can't find it just
by interface info. This patch adds usb id so the cdc-acm driver can
properly handle this combined device.

We where selecting wrong ep descriptors causing
some troubles while sending files over obex interface.
The problem was a typo while usb_find_endpoint() was being
called for HS endpoints.
