commit cd3c18ba2fac14b34d03cae111f215009735ea06 upstream.
Full-speed isoc endpoints specify interval in exponent based form in
frames, not microframes, so we need to adjust accordingly.
NEC xHCI host controllers will return an error code of 0x11 if a full
speed isochronous endpoint is added with the Interval field set to
something less than 3 (2^3 = 8 microframes, or one frame). It is
impossible for a full speed device to have an interval smaller than one
frame.
This was always an issue in the xHCI driver, but commit
dfa49c4ad120a784ef1ff0717168aa79f55a483a "USB: xhci - fix math in
xhci_get_endpoint_interval()" removed the clamping of the minimum value
in the Interval field, which revealed this bug.
This needs to be backported to stable kernels back to 2.6.31.

commit 3824c1ddaf744be44b170a335332b9d6afe79254 upstream.
Protocol stall should not be fatal while reading port or hub status as it is
transient state. Currently hub EP0 STALL during port status read results in
failed device enumeration. This has been observed with ST-Ericsson (formerly
Philips) USB 2.0 Hub (04cc:1521) after connecting keyboard.

commit b513d44751bfb609a3c20463f764c8ce822d63e9 upstream.
Dmitry's patch
dfa49c4ad120a784ef1ff0717168aa79f55a483a USB: xhci - fix math in xhci_get_endpoint_interval()
introduced a bug. The USB 2.0 spec says that full speed isochronous endpoints'
bInterval must be decoded as an exponent to a power of two (e.g. interval =
2^(bInterval - 1)). Full speed interrupt endpoints, on the other hand, don't
use exponents, and the interval in frames is encoded straight into bInterval.
Dmitry's patch was supposed to fix up the full speed isochronous to parse
bInterval as an exponent, but instead it changed the *interrupt* endpoint
bInterval decoding. The isochronous endpoint encoding was the same.
This caused full speed devices with interrupt endpoints (including mice, hubs,
and USB to ethernet devices) to fail under NEC 0.96 xHCI host controllers:
[ 100.909818] xhci_hcd 0000:06:00.0: add ep 0x83, slot id 1, new drop flags = 0x0, new add flags = 0x99, new slot info = 0x38100000
[ 100.909821] xhci_hcd 0000:06:00.0: xhci_check_bandwidth called for udev ffff88011f0ea000
...
[ 100.910187] xhci_hcd 0000:06:00.0: ERROR: unexpected command completion code 0x11.
[ 100.910190] xhci_hcd 0000:06:00.0: xhci_reset_bandwidth called for udev ffff88011f0ea000
When the interrupt endpoint was added and a Configure Endpoint command was
issued to the host, the host controller would return a very odd error message
(0x11 means "Slot Not Enabled", which isn't true because the slot was enabled).
Probably the host controller was getting very confused with the bad encoding.

commit 472b91274a6c6857877b5caddb875dcb5ecdfcb8 upstream.
composite.c always sets req->length to zero
and expects function driver's setup handlers
to return the amount of bytes to be used
on req->length. If we test against req->length
w_length will always be greater than req->length
thus making us always stall that particular
SEND_ENCAPSULATED_COMMAND request.
Tested against a Windows XP SP3.

commit dfa49c4ad120a784ef1ff0717168aa79f55a483a upstream.
When parsing exponent-expressed intervals we subtract 1 from the
value and then expect it to match with original + 1, which is
highly unlikely, and we end with frequent spew:
usb 3-4: ep 0x83 - rounding interval to 512 microframes
Also, parsing interval for fullspeed isochronous endpoints was
incorrect - according to USB spec they use exponent-based
intervals (but xHCI spec claims frame-based intervals). I trust
USB spec more, especially since USB core agrees with it.
This should be queued for stable kernels back to 2.6.31.

commit 94ae4976e253757e9b03a44d27d41b20f1829d80 upstream.
This patch (as1458) fixes a problem affecting ultra-reliable systems:
When hardware failover of an EHCI controller occurs, the data
structures do not get released correctly. This is because the routine
responsible for removing unused QHs from the async schedule assumes
the controller is running properly (the frame counter is used in
determining how long the QH has been idle) -- but when a failover
causes the controller to be electronically disconnected from the PCI
bus, obviously it stops running.
The solution is simple: Allow scan_async() to remove a QH from the
async schedule if it has been idle for long enough _or_ if the
controller is stopped.

My testprog do a lot of bitbang - after hours i got following warning and my machine lockups:
WARNING: at /build/buildd/linux-2.6.38/lib/kref.c:34
After debugging uss720 driver i discovered that the completion callback was called before
usb_submit_urb returns. The callback frees the request structure that is krefed on return by
usb_submit_urb.

commit b5a3b3d985493c173925907adfebf3edab236fe7 upstream.
This patch (as1453) fixes a long-standing bug in the ehci-hcd driver.
There is no need to set the Halt bit in the overlay region for an
unlinked or blocked QH. Contrary to what the comment says, setting
the Halt bit does not cause the QH to be patched later; that decision
(made in qh_refresh()) depends only on whether the QH is currently
pointing to a valid qTD. Likewise, setting the Halt bit does not
prevent completions from activating the QH while it is "stopped"; they
are prevented by the fact that qh_completions() temporarily changes
qh->qh_state to QH_STATE_COMPLETING.
On the other hand, there are circumstances in which the QH will be
reactivated _without_ being patched; this happens after an URB beyond
the head of the queue is unlinked. Setting the Halt bit will then
cause the hardware to see the QH with both the Active and Halt bits
set, an invalid combination that will prevent the queue from
advancing and may even crash some controllers.
Apparently the only reason this hasn't been reported before is that
unlinking URBs from the middle of a running queue is quite uncommon.
However Test 17, recently added to the usbtest driver, does exactly
this, and it confirms the presence of the bug.
In short, there is no reason to set the Halt bit for an unlinked or
blocked QH, and there is a very good reason not to set it. Therefore
the code that sets it is removed.

commit d14fc1a74e846d7851f24fc9519fe87dc12a1231 upstream.
Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced
.carrier_raised function in several drivers. That also means
tty_port_block_til_ready can now suspend the process trying to open the serial
port when Carrier Detect is low and put it into tty_port.open_wait queue. We
need to wake up the process when Carrier Detect goes high and trigger TTY
hangup when CD goes low.
Some of the devices do not report modem status line changes, or at least we
don't understand the status message, so for those we remove .carrier_raised
again.

commit 01a1fdb9a7afa5e3c14c9316d6f380732750b4e4 upstream.
When an endpoint stalls, we need to update the xHCI host's internal
dequeue pointer to move it past the stalled transfer. This includes
updating the cycle bit (TRB ownership bit) if we have moved the dequeue
pointer past a link TRB with the toggle cycle bit set.
When we're trying to find the new dequeue segment, find_trb_seg() is
supposed to keep track of whether we've passed any link TRBs with the
toggle cycle bit set. However, this while loop's body
while (cur_seg->trbs > trb ||
&cur_seg->trbs[TRBS_PER_SEGMENT - 1] < trb) {
Will never get executed if the ring only contains one segment.
find_trb_seg() will return immediately, without updating the new cycle
bit. Since find_trb_seg() has no idea where in the segment the TD that
stalled was, make the caller, xhci_find_new_dequeue_state(), check for
this special case and update the cycle bit accordingly.
This patch should be queued to kernels all the way back to 2.6.31.

commit b14e840d04dba211fbdc930247e379085623eacd upstream.
The document says:
|2.1 Problem description
| When at least two USB devices are simultaneously running, it is observed that
| sometimes the INT corresponding to one of the USB devices stops occurring. This may
| be observed sometimes with USB-to-serial or USB-to-network devices.
| The problem is not noticed when only USB mass storage devices are running.
|2.2 Implication
| This issue is because of the clearing of the respective Done Map bit on reading the ATL
| PTD Done Map register when an INT is generated by another PTD completion, but is not
| found set on that read access. In this situation, the respective Done Map bit will remain
| reset and no further INT will be asserted so the data transfer corresponding to that USB
| device will stop.
|2.3 Workaround
| An SOF INT can be used instead of an ATL INT with polling on Done bits. A time-out can
| be implemented and if a certain Done bit is never set, verification of the PTD completion
| can be done by reading PTD contents (valid bit).
| This is a proven workaround implemented in software.
Russell King run into this with an USB-to-serial converter. This patch
implements his suggestion to enable the high frequent SOF interrupt only
at the time we have ATL packages queued. It goes even one step further
and enables the SOF interrupt only if we have more than one ATL packet
queued at the same time.

commit bcd2fde05341cef0052e49566ec88b406a521cf3 upstream.
The expression
while (running_total < sg_dma_len(sg))
does not take into account that the remaining data length can be less
than sg_dma_len(sg). In that case, running_total can end up being
greater than the total data length, so an extra TRB is counted.
Changing the expression to
while (running_total < sg_dma_len(sg) && running_total < temp)
fixes that.

commit 5807795bd4dececdf553719cc02869e633395787 upstream.
Calculations like
running_total = TRB_MAX_BUFF_SIZE -
(sg_dma_address(sg) & (TRB_MAX_BUFF_SIZE - 1));
if (running_total != 0)
num_trbs++;
are incorrect, because running_total can never be zero, so the if()
expression will never be true. I think the intention was that
running_total be in the range of 0 to TRB_MAX_BUFF_SIZE-1, not 1
to TRB_MAX_BUFF_SIZE. So adding a
running_total &= TRB_MAX_BUFF_SIZE - 1;
fixes the problem.

Note: This patch changes the expressions containing

"(TRB_MAX_BUFF_SIZE - 1)". No change in behavior is intended for
those expressions.

My Galaxy Spica needs this quirk when in modem mode, otherwise
it causes endless USB bus resets and is unusable in this mode.
Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500

That's why in addition to this patch the visor driver must be prevented
from binding to SPH-I500 ID, so ACM driver can do that.

[USB]Add Samsung SGH-I500/Android modem ID switch to visor driver
Samsung decided to reuse USB ID of its old CDMA phone SGH-I500 for the
modem part of some of their Android phones. At least Galaxy Spica
is affected.
This modem needs ACM driver and does not work with visor driver which
binds the conflicting ID for SGH-I500.
Because SGH-I500 is pretty an old hardware its best to add switch to
visor
driver in cause somebody still wants to use that phone with Linux.
Note that this is needed only when using the Android phone as modem,
not in USB storage or ADB mode.

commit b193b412e62b134adf69af286c7e7f8e99259350 upstream.
Cancel idle timer in musb_platform_exit.
The idle timer could trigger after clock had been disabled leading to
kernel panic when MUSB_DEVCTL is accessed in musb_do_idle on 2.6.37.
The fault below is no longer triggered on 2.6.38-rc4 (clock is disabled
later, and only if compiled as a module, and the offending memory access
has moved) but the timer should be cancelled nonetheless.

commit 653a39d1f61bdc9f277766736d21d2e9be0391cb upstream.
When there's an xHCI host power loss after a suspend from memory, the USB
core attempts to reset and verify the USB devices that are attached to the
system. The xHCI driver has to reallocate those devices, since the
hardware lost all knowledge of them during the power loss.
When a hub is plugged in, and the host loses power, the xHCI hardware
structures are not updated to say the device is a hub. This is usually
done in hub_configure() when the USB hub is detected. That function is
skipped during a reset and verify by the USB core, since the core restores
the old configuration and alternate settings, and the hub driver has no
idea this happened. This bug makes the xHCI host controller reject the
enumeration of low speed devices under the resumed hub.
Therefore, make the USB core re-setup the internal xHCI hub device
information by calling update_hub_device() when hub_activate() is called
for a hub reset resume. After a host power loss, all devices under the
roothub get a reset-resume or a disconnect.
This patch should be queued for the 2.6.37 stable tree.

commit 96a3e79edff6f41b0f115a82f1a39d66218077a7 upstream.
Added 0x0307 device id to support Motorola cables to the pl2303 usb
serial driver. This cable has a modified chip that is a pl2303, but
declares itself as 0307. Fixed by adding the right device id to the
supported devices list, assigning it the code labeled
PL2303_PRODUCT_ID_MOTOROLA.

commit 18344a1cd5889d48dac67229fcf024ed300030d5 upstream.
I tried a magnetic stripe reader
(http://www.kimaldi.com/kimaldi_eng/productos/lectores_de_tarjetas/lectores_tarjeta_chip_y_dni/lector_hibrido_uniform_hcr_331)
and I see that it is interfaced with a PL2303. I wrote a patch to use
your driver which simply adds the product ID for the device and it
seems working fine.

commit d199c96d41d80a567493e12b8e96ea056a1350c1 upstream.
If anyone comes across a high-speed hub that (by mistake or by design)
claims to have no Transaction Translators, plugging a full- or
low-speed device into it will cause the USB stack to crash. This
patch (as1446) prevents the problem by ignoring such devices, since
the kernel has no way to communicate with them.

commit 271c1150b4f8e1685e5a8cbf76e329ec894481da upstream.
The major and minor number saved in the product_info structure
were copied from the address instead of the data, causing an
inconsistency in the reported versions during firmware loading:
usb 4-1: firmware: requesting edgeport/down.fw
/usr/src/linux/drivers/usb/serial/io_edgeport.c: downloading firmware version (930) 1.16.4
[..]
/usr/src/linux/drivers/usb/serial/io_edgeport.c: edge_startup - time 3 4328191260
/usr/src/linux/drivers/usb/serial/io_edgeport.c: FirmwareMajorVersion 0.0.4
This can cause some confusion whether firmware loaded successfully
or not.

commit ad84e4a9efb7c8ed322bafb6ebdb9c3a49a3d3a8 upstream.
This patch (as1442) fixes a bug in g_printer: Module parameters should
not be marked "__initdata" if they are accessible in sysfs (i.e., if
the mode value in the module_param() macro is nonzero). Otherwise
attempts to access the parameters will cause addressing violations.
Character-string module parameters must not be marked "__initdata"
if the module can be unloaded, because the kernel needs to access the
parameter variable at unload time in order to free the
dynamically-allocated string.

commit f75593ceaa08e6d27aec1a5de31cded19e850dd1 upstream.
This patch (as1440) fixes a bug in ehci-hcd. ehci->periodic_size is
used to compute the size in a dma_alloc_coherent() call, but then it
gets changed later on. As a result, the corresponding call to
dma_free_coherent() passes a different size from the original
allocation. Fix the problem by adjusting ehci->periodic_size before
carrying out any of the memory allocations.
