9cef310fcd llc: llc_cmsg_rcv was getting called after sk_eat_skb.
Received non stream protocol packets were calling llc_cmsg_rcv that used a
skb after that skb was released by sk_eat_skb. This caused received STP

In case a conditional jump is followed by a long jump, conditional jump

96f1f05af7 iwlwifi: update SCD BC table for all SCD queues
Since we configure all the queues as CHAINABLE, we need to update the
byte count for all the queues, not only the AGGREGATABLE ones.

Not doing so can confuse the SCD and make the fw assert.

04ded16724 RDMA/cma: Verify private data length
private_data_len is defined as a u8.  If the user specifies a large
private_data size (> 220 bytes), we will calculate a total length that
exceeds 255, resulting in private_data_len wrapping back to 0.  This
can lead to overwriting random kernel memory.  Avoid this by verifying
that the resulting size fits into a u8.

e0197aae59 cgroups: fix a css_set not found bug in cgroup_attach_proc
There is a BUG when migrating a PF_EXITING proc. Since css_set_prefetch()
is not called for the PF_EXITING case, find_existing_css_set() will return
NULL inside cgroup_task_migrate() causing a BUG.

This bug is easy to reproduce. Create a zombie and echo its pid to
cgroup.procs.

$ cat zombie.c
\#include <unistd.h>

int main()
{
  if (fork())
      pause();
  return 0;
}
$

We are hitting this bug pretty regularly on ChromeOS.

This bug is already fixed by Tejun Heo's cgroup patchset which is
targetted for the next merge window:

https://lkml.org/lkml/2011/11/1/356

I've create a smaller patch here which just fixes this bug so that a
fix can be merged into the current release and stable.

913050b91e oprofile: Fix uninitialized memory access when writing to writing to oprofilefs
If oprofilefs_ulong_from_user() is called with count equals
zero, *val remains unchanged. Depending on the implementation it
might be uninitialized.

Change oprofilefs_ulong_from_user()'s interface to return count
on success. Thus, we are able to return early if count equals
zero which avoids using *val uninitialized. Fixing all users of
oprofilefs_ulong_ from_user().

This follows write syscall implementation when count is zero:
"If count is zero ... [and if] no errors are detected, 0 will be
returned without causing any other effect." (man 2 write)

7422ba5343 usb: gadget: epautoconf: do not change number of streams
We should not change gadget driver's descriptors just
because we think it's right to do so.

There are several of reasons which would support this
statement but it suffices to say that this was probably
never tested because it updates bmAttributes without
asking the driver if it's ok to do so.

This means that e.g. on UASP gadget it would enable
stream support even for the command endpoint which must
not have stream support enabled.

In fact, this change is fixing the bug introduced by
commit a59d6b9 (usb: gadget: add streams support to
the gadget framework) which was caught when testing
UASP gadget with dwc3 driver.

79e654787c Bluetooth: Clear RFCOMM session timer when disconnecting last channel
When the last RFCOMM data channel is closed, a timer is normally set
up to disconnect the control channel at a later time.  If the control
channel disconnect command is sent with the timer pending, the timer
needs to be cancelled.

If the timer is not cancelled in this situation, the reference
counting logic for the RFCOMM session does not work correctly when the
remote device closes the L2CAP connection.  The session is freed at
the wrong time, leading to a kernel panic.

497f16f21a pci: Fix hotplug of Express Module with pci bridges
I noticed that hotplug of one setup does not work with recent change in
pci tree.

After checking the bridge conf setup, I noticed that the bridges get
assigned but do not get enabled.

The reason is the following commit, while simply ignores bridge
resources when enabling a pci device:

| commit bbef98ab0f
| Author: Ram Pai <linuxram@us.ibm.com>
| Date:   Sun Nov 6 10:33:10 2011 +0800
|
|    PCI: defer enablement of SRIOV BARS
|...
|    NOTE: Note, there is subtle change in the pci_enable_device() API.  Any
|    driver that depends on SRIOV BARS to be enabled in pci_enable_device()
|    can fail.

Put back bridge resource and ROM resource checking to fix the problem.

That should fix regression like BIOS does not assign correct resource to
bridge.

Commit 5c48b108 ("um: take arch/um/sys-x86 to arch/x86/um") broke the
make target update-po-config, as its symlink trick (again) fails.
(Previous breakage was fixed with commit bdc69ca4 ("kconfig: change
update-po-config to reflect new layout of arch/um").)

The new UML layout allows to drop the symlick trick entirely. And if,
one day, another architecture supports UML too, that should now work
without again breaking this make target.

142349f541 btrfs: lower the dirty balance poll interval

next check point selected by the dirty throttling algorithm.
