usb: serial: mos7840: Add USB IDs to support more B&B USB/RS485 converters.

commit 870408c8291015872a7a0b583673a9e56b3e73f4 upstream.

Add the USB IDs needed to support the B&B USOPTL4-4P, USO9ML2-2P, and
USO9ML2-4P.  This patch expands and corrects a typo in the patch sent
on 08-31-2010.

ima: always maintain counters

commit e950598d43dce8d97e7d5270808393425d1e5cbd upstream.

commit 8262bb85da allocated the inode integrity struct (iint) before any
inodes were created. Only after IMA was initialized in late_initcall were
the counters updated. This patch updates the counters, whether or not IMA
has been initialized, to resolve 'imbalance' messages.

This patch fixes the bug as reported in bugzilla: 15673.  When the i915
is builtin, the ring_buffer is initialized before IMA, causing the
imbalance message on suspend.

USB: cxacru: Use a bulk/int URB to access the command endpoint

commit 902ffc3c707c1d459ea57428a619a807cbe412f9 upstream.

The command endpoint is either a bulk or interrupt endpoint, but using
the wrong type of transfer causes an error if CONFIG_USB_DEBUG is
enabled after commit f661c6f8c67bd55e93348f160d590ff9edf08904, which
checks for this mismatch.

Detect which type of endpoint it is and use a bulk/int URB as
appropriate. There are other function calls specifying a bulk pipe,
but usb_clear_halt doesn't use the pipe type (only the endpoint) and
usb_bulk_msg auto-detects interrupt transfers.

USB: cdc-acm: Adding second ACM channel support for various Nokia and one Samsung phones

commit 4035e45632c2a8bb4edae83c20447051bd9a9604 upstream.

S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem
with a standard AT-command interface, which is picked up correctly by CDC-ACM.

The second ACM port is marked as having a vendor-specific protocol. This means
that the ACM driver will not claim the second channel by default.

This adds support for the second ACM channel for the following devices:
    Nokia E63
    Nokia E75
    Nokia 6760 Slide
    Nokia E52
    Nokia E55
    Nokia E72
    Nokia X6

USB: cdc-acm: Fixing crash when ACM probing interfaces with no endpoint descriptors.

commit 577045c0a76e34294f902a7d5d60e90b04d094d0 upstream.

Certain USB devices, such as the Nokia X6 mobile phone, don't expose any
endpoint descriptors on some of their interfaces. If the ACM driver is forced
to probe all interfaces on a device the a NULL pointer dereference will occur
when the ACM driver attempts to use the endpoint of the alternative settings.
One way to get the ACM driver to probe all the interfaces is by using the
/sys/bus/usb/drivers/cdc_acm/new_id interface.

This patch checks that the endpoint pointer for the current alternate settings
is non-NULL before using it.

ALSA: usb-audio: fix detection of vendor-specific device protocol settings

commit a2acad8298a42b7be684a32fafaf83332bba9c2b upstream.

The Audio Class v2 support code in 2.6.35 added checks for the
bInterfaceProtocol field.  However, there are devices (usually those
detected by vendor-specific quirks) that do not have one of the
predefined values in this field, which made the driver reject them.

To fix this regression, restore the old behaviour, i.e., assume that
a device with an unknown bInterfaceProtocol field (other than
UAC_VERSION_2) has more or less UAC-v1-compatible descriptors.

ALSA: virtuoso: work around missing reset in the Xonar DS Windows driver

commit 4c25b93223340deff73381cc47f9244fb379a74d upstream.

For the WM8776 chip, this driver uses a different sample format and
more features than the Windows driver.  When rebooting from Linux into
Windows, the latter driver does not reset the chip but assumes all its
registers have their default settings, so we get garbled sound or, if
the output happened to be muted before rebooting, no sound.

To make that driver happy, hook our driver's cleanup function into the
shutdown notifier and ensure that the chip gets reset.

ALSA: virtuoso: fix setting of Xonar DS line-in/mic-in controls

commit fe6ce80ae25953d95ebaf9bce27b585218cda25c upstream.

The Line and Mic inputs cannot be used at the same time, so the driver
has to automatically disable one of them if both are set.  However, it
forgot to notify userspace about this change, so the mixer state would
be inconsistent.  To fix this, check if the other control gets muted,
and send a notification event in this case.

ALSA: seq/oss - Fix double-free at error path of snd_seq_oss_open()

commit 27f7ad53829f79e799a253285318bff79ece15bd upstream.

The error handling in snd_seq_oss_open() has several bad codes that
do dereferecing released pointers and double-free of kmalloc'ed data.
The object dp is release in free_devinfo() that is called via
private_free callback.  The rest shouldn't touch this object any more.

The patch changes delete_port() to call kfree() in any case, and gets
rid of unnecessary calls of destructors in snd_seq_oss_open().

Fixes CVE-2010-3080.

ALSA: usb-audio: Assume first control interface is for audio

commit 7b6717e144de6592e614fd7fc3b914b6bf686a9d upstream.

For devices with more than one control interface, let's assume the first
one contains the audio controls. Unfortunately, there is no field in any
of the descriptors to tell us whether a control interface is for audio
or MIDI controls, so a better check is not easy to implement.

On a composite device with audio and MIDI functions, for example, the
code currently overwrites chip->ctrl_intf, causing operations on the
control interface to fail if they are issued after the device probe.

swap: prevent reuse during hibernation

commit b73d7fcecd93dc15eaa3c45c8c587b613f6673c4 upstream.

Move the hibernation check from scan_swap_map() into try_to_free_swap():
to catch not only the common case when hibernation's allocation itself
triggers swap reuse, but also the less likely case when concurrent page
reclaim (shrink_page_list) might happen to try_to_free_swap from a page.

Hibernation already clears __GFP_IO from the gfp_allowed_mask, to stop
reclaim from going to swap: check that to prevent swap reuse too.

swap: discard while swapping only if SWAP_FLAG_DISCARD

commit 3399446632739fcd05fd8b272b476a69c6e6d14a upstream.

Tests with recent firmware on Intel X25-M 80GB and OCZ Vertex 60GB SSDs
show a shift since I last tested in December: in part because of firmware
updates, in part because of the necessary move from barriers to awaiting
completion at the block layer.  While discard at swapon still shows as
slightly beneficial on both, discarding 1MB swap cluster when allocating
is now disadvanteous: adds 25% overhead on Intel, adds 230% on OCZ (YMMV).

Surrender: discard as presently implemented is more hindrance than help
for swap; but might prove useful on other devices, or with improvements.
So continue to do the discard at swapon, but make discard while swapping
conditional on a SWAP_FLAG_DISCARD to sys_swapon() (which has been using
only the lower 16 bits of int flags).

We can add a --discard or -d to swapon(8), and a "discard" to swap in
/etc/fstab: matching the mount option for btrfs, ext4, fat, gfs2, nilfs2.

swap: do not send discards as barriers

commit 8f2ae0faa3a119158c4dcfe89926d6fad5f5332c upstream.

The swap code already uses synchronous discards, no need to add I/O
barriers.

This fixes the worst of the terrible slowdown in swap allocation for
hibernation, reported on 2.6.35 by Nigel Cunningham; but does not entirely
eliminate that regression.
