d44697e328 msm-pcm-q6: Add support for flexible recording period size
- Current implementation supports only fixed buffer size
  of 320 bytes only for audio recording. This results in
  performance overhead for recording at higher sample rate.
- Added support for flexible period size so that user can
  use larger buffers for recording at higher sample rates.

When usb mode is changed from MTP to Tethering, chg_gone_irq_handler is called
and then disconnect tethering by turning off ovpfet from unplug_ovp_fet_open.
So we add under threshold to protect this error while usb is being connected.

4172e74684 ASoC: wcd9310: Turn off slimbus clocks when no ports are active
With the recent change in tabla shutdown, turning off the clocks
were being taken care after all the slimbus ports are closed.
But, there are instants where tabla startup is being called
during bootup, which keeps the runtime PM votes running,
and as there are no ports open, clocks are on all the time,
due to one of the votes. Bringing back tabla shutdown, but
turn off the clocks only if there are no slimbus ports
open at the time of shutdown, else it will taken care when
the slimbus ports are getting closed

9af01d4b75 usb: gadget: prevent change of Host MAC address of 'usb0' interface
On windows 7 platform, previously allocated ip address is maintained.
However, Host MAC address of 'usb0' interface is changed when the
tethering driver re-enumerated. Thus, the tethering network driver
can't be allocated ip address from dhcp. It causes connection delay
between host and phone for usb tethering.

This patch prevents from changing Host MAC address of 'usb0' interface.
In other words, this patch maintains the Host MAC address allocated when
first tethering driver although the driver is re-enumerated. However,
after reboot, the Host MAC address can be changed.

a74eef8bc8 usb: gadget: Fix g_ether interface link status
A "usb0" interface that has never been connected to a host has an unknown
operstate, and therefore the IFF_RUNNING flag is (incorrectly) asserted
when queried by ifconfig, ifplugd, etc.  This is a result of calling
netif_carrier_off() too early in the probe function; it should be called
after register_netdev().

Similar problems have been fixed in many other drivers, e.g.:

e826eafa6 (bonding: Call netif_carrier_off after register_netdevice)
0d672e9f8 (drivers/net: Call netif_carrier_off at the end of the probe)
6a3c869a6 (cxgb4: fix reported state of interfaces without link)

Fix is to move netif_carrier_off() to the end of the function.

    New Features:
    1. Sessionize SME scan cache
    2. Separate beacon & porbe rsp entry for PE scan cache
    3. Enable scan break down logic in SME for multi-session

    Fixes:
    The change fixes issue with host initiated scans interferring with WFD
    connection and causing jitter in the video stream on the WFD
    connection.  This partially addresses b/7138968.

   3. Enable scan break down logic in SME for multi-session

   Fixes:
   The change fixes issue with host initiated scans interferring with WFD
   connection and causing jitter in the video stream on the WFD
   connection

-- IMPS mode, TX COMP interrupt flooding fix:

   To stop TX COMP interrupt with IMPS mode, RIVA shuld power down. But
   whatever reason, if RIVA could not power down, TX COMP INT could not
   be cleared and infinite INT may happen

-- Fix for issue RIVA does not seem to be getting into BMPS mode:

   The reason riva does not enter in to power save is because after the
   connection to the AP (Configured 40Mhz channel in 2.4Ghz) the driver
   sends the invalid cb mode in the finish scan request to the Riva if we
   are in scan window. The issue does not show up if we are not in scan
   window.

   The reason driver sends the invalid cb mode is because after receiving
   the join beacon the variable psessionEntry->htSecondaryChannelOffset
   in the function limCheckAndAnnounceJoinSuccess is over writing with
   the AP secondary offset.

This causes delay in processing the ISR before it is returned causing other

855ae3da46 msm: kgsl: Add support for Android's sync point framework
The Android sync point framework will replace the synchronization
previously implemented by genlock. This change implements the KGSL
component of the sync point framework by creating a fence that is
automatically signaled by KGSL when it's timestamp expires. The
fence FD is returned to the user driver so that another process
can wait for the sync point.

You can set the value of amp from 0 to 100.
If you want to vibrate inversely, you can set from 0 to -100.

85c85ee651 netlink: fix possible spoofing from non-root processes
Non-root user-space processes can send Netlink messages to other
processes that are well-known for being subscribed to Netlink
asynchronous notifications. This allows ilegitimate non-root
process to send forged messages to Netlink subscribers.

The userspace process usually verifies the legitimate origin in
two ways:

a) Socket credentials. If UID != 0, then the message comes from
   some ilegitimate process and the message needs to be dropped.

b) Netlink portID. In general, portID == 0 means that the origin
   of the messages comes from the kernel. Thus, discarding any
   message not coming from the kernel.

However, ctnetlink sets the portID in event messages that has
been triggered by some user-space process, eg. conntrack utility.
So other processes subscribed to ctnetlink events, eg. conntrackd,
know that the event was triggered by some user-space action.

Neither of the two ways to discard ilegitimate messages coming
from non-root processes can help for ctnetlink.

This patch adds capability validation in case that dst_pid is set
in netlink_sendmsg(). This approach is aggressive since existing
applications using any Netlink bus to deliver messages between
two user-space processes will break. Note that the exception is
NETLINK_USERSOCK, since it is reserved for netlink-to-netlink
userspace communication.

Still, if anyone wants that his Netlink bus allows netlink-to-netlink
userspace, then they can set NL_NONROOT_SEND. However, by default,
I don't think it makes sense to allow to use NETLINK_ROUTE to
communicate two processes that are sending no matter what information
that is not related to link/neighbouring/routing. They should be using
NETLINK_USERSOCK instead for that.

204ebe9035 af_netlink: force credentials passing [CVE-2012-3520]
Pablo Neira Ayuso discovered that avahi and
potentially NetworkManager accept spoofed Netlink messages because of a
kernel bug.  The kernel passes all-zero SCM_CREDENTIALS ancillary data
to the receiver if the sender did not provide such data, instead of not
including any such data at all or including the correct data from the
peer (as it is the case with AF_UNIX).

This bug was introduced in commit 16e5726269
(af_unix: dont send SCM_CREDENTIALS by default)

This patch forces passing credentials for netlink, as
before the regression.

Another fix would be to not add SCM_CREDENTIALS in
netlink messages if not provided by the sender, but it
might break some programs.

With help from Florian Weimer & Petr Matousek

This issue is designated as CVE-2012-3520
