commit f8264340e694604863255cc0276491d17c402390 upstream.
According to XHCI specification (5.5.2.1) the IP is bit 0 and IE is bit 1
of IMAN register. Previously their definitions were reversed.
Even though there are no ill effects being observed from the swapped
definitions (because IMAN_IP is RW1C and in legacy PCI case we come in
with it already set to 1 so it was clearing itself even though we were
setting IMAN_IE instead of IMAN_IP), we should still correct the values.

commit feca7746d5d9e84b105a613b7f3b6ad00d327372 upstream.
This patch (as1661) fixes a rather obscure bug in ehci-hcd. In a
couple of places, the driver compares the DMA address stored in a QH's
overlay region with the address of a particular qTD, in order to see
whether that qTD is the one currently being processed by the hardware.
(If it is then the status in the QH's overlay region is more
up-to-date than the status in the qTD, and if it isn't then the
overlay's value needs to be adjusted when the QH is added back to the
active schedule.)
However, DMA address in the overlay region isn't always valid. It
sometimes will contain a stale value, which may happen by coincidence
to be equal to a qTD's DMA address. Instead of checking the DMA
address, we should check whether the overlay region is active and
valid. The patch tests the ACTIVE bit in the overlay, and clears this
bit when the overlay becomes invalid (which happens when the
currently-executing URB is unlinked).
This is the second part of a fix for the regression reported at:

commit ab4b71644a26d1ab92b987b2fd30e17c25e89f85 upstream.
This reverts commit 200e0d99 ("USB: storage: optimize to match the
Huawei USB storage devices and support new switch command" and the
followup bugfix commit cd060956 ("USB: storage: properly handle
the endian issues of idProduct").
The commit effectively added a large number of Huawei devices to
the deprecated usb-storage mode switching logic. Many of these
devices have been in use and supported by the userspace
usb_modeswitch utility for years. Forcing the switching inside
the kernel causes a number of regressions as a result of ignoring
existing onfigurations, and also completely takes away the ability
to configure mode switching per device/system/user.
Known regressions caused by this:
- Some of the devices support multiple modes, using different
switching commands. There are existing configurations taking
advantage of this.
- There is a real use case for disabling mode switching and
instead mounting the exposed storage device. This becomes
impossible with switching logic inside the usb-storage driver.
- At least on device fail as a result of the usb-storage switching
command, becoming completely unswitchable. This is possibly a
firmware bug, but still a regression because the device work as
expected using usb_modeswitch defaults.
In-kernel mode switching was deprecated years ago with the
development of the more user friendly userspace alternatives. The
existing list of devices in usb-storage was only kept to prevent
breaking already working systems. The long term plan is to remove
the list, not to add to it. Ref:

commit 1f3f687722fd9b29a0c2a85b4844e3b2a3585c63 upstream.
The USB device descriptor of one identity presented by a few
Huawei morphing devices have serial functions with class codes
02/02/ff, indicating CDC ACM with a vendor specific protocol. This
combination is often used for MSFT RNDIS functions, and the CDC
ACM class driver will therefore ignore such functions.
The CDC ACM class driver cannot support functions with only 2
endpoints. The underlying serial functions of these modems are
also believed to be the same as for alternate device identities
already supported by the option driver. Letting the same driver
handle these functions independently of the current identity
ensures consistent handling and user experience.
There is no need to blacklist these devices in the rndis_host
driver. Huawei serial functions will either have only 2 endpoints
or a CDC ACM functional descriptor with bmCapabilities != 0, making
them correctly ignored as "non RNDIS" by that driver.

commit 3e619d04159be54b3daa0b7036b0ce9e067f4b5d upstream.
This patch (as1654) fixes a very old bug in ehci-hcd, connected with
scheduling of periodic split transfers. The calculations for
full/low-speed bus usage are all carried out after the correction for
bit-stuffing has been applied, but the values in the max_tt_usecs
array assume it hasn't been. The array should allow for allocation of
up to 90% of the bus capacity, which is 900 us, not 780 us.
The symptom caused by this bug is that any isochronous transfer to a
full-speed device with a maxpacket size larger than about 980 bytes is
always rejected with a -ENOSPC error.

commit 0f815a0a700bc10547449bde6c106051a035a1b9 upstream.
This patch (as1644) fixes a race that occurs during startup in
uhci-hcd. If the IRQ line is shared with other devices, it's possible
for the handler routine to be called before the data structures are
fully initialized.
The problem is fixed by adding a check to the IRQ handler routine. If
the initialization hasn't finished yet, the routine will return
immediately.

commit 68e5254adb88bede68285f11fb442a4d34fb550c upstream.
xhci_alloc_segments_for_ring() builds a list of xhci_segments and links
the tail to head at the end (forming a ring). When it bails out for OOM
reasons half-way through, it tries to destroy its half-built list with
xhci_free_segments_for_ring(), even though it is not a ring yet. This
causes a null-pointer dereference upon hitting the last element.
Furthermore, one of its callers (xhci_ring_alloc()) mistakenly believes
the output parameters to be valid upon this kind of OOM failure, and
calls xhci_ring_free() on them. Since the (incomplete) list/ring should
already be destroyed in that case, this would lead to a use after free.
This patch fixes those issues by having xhci_alloc_segments_for_ring()
destroy its half-built, non-circular list manually and destroying the
invalid struct xhci_ring in xhci_ring_alloc() with a plain kfree().
This patch should be backported to kernels as old as 2.6.31, that
contains the commit 0ebbab37422315a5d0cb29792271085bafdf38c0 "USB: xhci:
Ring allocation and initialization."
A separate patch will need to be developed for kernels older than 3.4,
since the ring allocation code was refactored in that kernel.

commit 36caff5d795429c572443894e8789c2150dd796b upstream.
This patch (as1631) fixes a bug that shows up when a config change
fails for a device under an xHCI controller. The controller needs to
be told to disable the endpoints that have been enabled for the new
config. The existing code does this, but before storing the
information about which endpoints were enabled! As a result, any
second attempt to install the new config is doomed to fail because
xhci-hcd will refuse to enable an endpoint that is already enabled.
The patch optimistically initializes the new endpoints' device
structures before asking the device to switch to the new config. If
the request fails then the endpoint information is already stored, so
we can use usb_hcd_alloc_bandwidth() to disable the endpoints with no
trouble. The rest of the error path is slightly more complex now; we
have to disable the new interfaces and call put_device() rather than
simply deallocating them.

commit 55c1945edaac94c5338a3647bc2e85ff75d9cf36 upstream.
A high speed control or bulk endpoint may have bInterval set to zero,
which means it does not NAK. If bInterval is non-zero, it means the
endpoint NAKs at a rate of 2^(bInterval - 1).
The xHCI code to compute the NAK interval does not handle the special
case of zero properly. The current code unconditionally subtracts one
from bInterval and uses it as an exponent. This causes a very large
bInterval to be used, and warning messages like these will be printed:
usb 1-1: ep 0x1 - rounding interval to 32768 microframes, ep desc says 0 microframes
This may cause the xHCI host hardware to reject the Configure Endpoint
command, which means the HS device will be unusable under xHCI ports.
This patch should be backported to kernels as old as 2.6.31, that contain
commit dfa49c4ad120a784ef1ff0717168aa79f55a483a "USB: xhci - fix math in

commit 07e72b95f5038cc82304b9a4a2eb7f9fc391ea68 upstream.
Some touchscreens have buggy firmware which claims
remote wakeup to be enabled after a reset. They nevertheless
crash if the feature is cleared by the host.
Add a check for reset resume before checking for
an enabled remote wakeup feature. On compliant
devices the feature must be cleared after a reset anyway.

commit 77c7f072c87fa951e9a74805febf26466f31170c upstream.
John's NEC 0.96 xHCI host controller needs a longer timeout for a warm
reset to complete. The logs show it takes 650ms to complete the warm
reset, so extend the hub reset timeout to 800ms to be on the safe side.

commit 1d16638e3b9cc195bac18a8fcbca748f33c1bc24 upstream.
If we do have endpoints named like "ep-a" then bEndpointAddress is
counted internally by the gadget framework.
If we do have endpoints named like "ep-1" then bEndpointAddress is
assigned from the digit after "ep-".
If we do have both, then it is likely that after we used up the
"generic" endpoints we will use the digits and thus assign one
bEndpointAddress to multiple endpoints.
This theory can be proofed by using the completely enabled g_multi.
Without this patch, the mass storage won't enumerate and times out
because it shares endpoints with RNDIS.
This patch also adds fills up the endpoints list so we have in total
endpoints 1 to 15 in + out available while some of them are restricted
to certain types like BULK or ISO. Without this change the nokia gadget
won't load because the system does not provide enough (BULK) endpoints
but it did before ep-a - ep-f were removed.
