Merge branch 'v4l_for_linus' of git://git./linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:
 "Media fixes for:
   - one Kconfig fix patch;
   - one patch fixing DocBook breakage due to the drivers/media UAPI
     changes;
   - the remaining UAPI media changes (DVB API).

  I'm aware that is is a little late for the UAPI renames for the DVB
  API, but IMHO, it is better to merge it for 3.7, due to two reasons:

   1) There is a major rename at 3.7 (not only uapi changes, but also
      the entire media drivers were reorganized on 3.7, in order to
      simplify the Kconfig logic, and easy drivers selection, especially
      for hybrid devices).  By confining all those renames there at 3.7
      it will cause all the harm at for media developers on just one
      shot.  Stable backports upstream and at distros will likely
      welcome it as well, as they won't need to check what changed on
      3.7 and what was postponed for on 3.8.

   2) The V4L2 DocBook Makefile creates a cross-reference between the
      media API headers and the specs.  This helps us _a_lot_ to be sure
      that all API improvements are properly documented.  Every time a
      header changes from one place to another, DocBook/media/Makefile
      needs to be patched.  Currently, the DocBook breakage patch
      depends on the DVB UAPI."

7 years agocrypto: aesni - fix XTS mode on x86-32, add wrapper function for asmlinkage aesni_enc()

7 years agofs, xattr: fix bug when removing a name not in xattr list
David Rientjes [Thu, 18 Oct 2012 03:41:15 +0000]
fs, xattr: fix bug when removing a name not in xattr list

Commit 38f38657444d ("xattr: extract simple_xattr code from tmpfs") moved
some code from tmpfs but introduced a subtle bug along the way.

If the name passed to simple_xattr_remove() does not exist in the list of
xattrs, then it is possible to call kfree(new_xattr) when new_xattr is
actually initialized to itself on the stack via uninitialized_var().

This causes a BUG() since the memory was not allocated via the slab
allocator and was not bypassed through to the page allocator because it
was too large.

Initialize the local variable to NULL so the kfree() never takes place.

7 years agocpuidle/powerpc: Fix snooze state problem in the cpuidle design on pseries.
Deepthi Dharwar [Wed, 3 Oct 2012 18:42:26 +0000]
cpuidle/powerpc: Fix snooze state problem in the cpuidle design on pseries.

Earlier without cpuidle framework on pseries, the native arch
idle routine comprised of both snooze and nap
states.  smt_snooze_delay variable was used to delay
the idle process entry to deeper idle state like  nap.
With the coming of cpuidle, this arch specific idle was replaced
by two different idle routines, one for supporting snooze and other
for nap. This enabled addition of more
low level idle states on pseries in the future.

On adopting the generic cpuidle framework for POWER systems,
the decision of which idle state to choose from,  given a predicted
idle time is taken by the menu governor based on
target_residency and  exit_latency of the idle states.
target_residency is the minimum time to be resident in that idle state.
Exit_latency is time taken to exit out of idle state.
Deeper the idle state, both the target residency and exit latency
would be higher.

In the current design, smt_snooze_delay is used as target_residency
for the  snooze state which is incorrect, as it is not the
minimum but the maximum duration to be in snooze state.
This would  result in the governor in taking bad decision,
as presently target_residency of nap < target_residency of snooze
inspite of nap being deeper idle state.

This patch aims to fix this problem by replacing the smt_snooze_delay loop
in snooze state, with the need_resched()  as the governor is aware of
entry and exit of various idle transitions based on which
next idle time prediction.

The governor is intelligent enough to determine the idle state the needs to
be transitioned to and maintains a whole of heuristics including
io load, previous idle states predictions etc for the same, based on
which idle state entry decision is taken.

With this fix, of setting target_residency of snooze to 0
     nap to smt_snooze_delay
if the predicted idle time is less
than smt_snooze_delay (target_residency of nap)
value governor would pick snooze state, else nap. This adhers to the
previous native idle design.

7 years agocpuidle/powerpc: Fix smt_snooze_delay functionality.
Deepthi Dharwar [Wed, 3 Oct 2012 18:42:18 +0000]
cpuidle/powerpc: Fix smt_snooze_delay functionality.

smt_snooze_delay was designed to  delay idle loop's nap entry
in the native idle code before it got  ported over to use as part of
the cpuidle framework.

A -ve value  assigned to smt_snooze_delay should result in
busy looping, in other words disabling the entry to nap state.

- https://lists.ozlabs.org/pipermail/linuxppc-dev/2010-May/082450.html

This particular functionality can be achieved currently by
echo 1 > /sys/devices/system/cpu/cpu*/state1/disable
but it is broken when one assigns -ve value to  the smt_snooze_delay
variable either via sysfs entry or ppc64_cpu util.

This patch aims to fix this, by disabling nap state when smt_snooze_delay
variable is set to -ve value.

Remove the redundant target residency initialisation in pseries_cpuidle_driver_init().
This is currently over-writing the residency time updated as part of the static
table, resulting in  all the idle states having the same target
residency of 100us which is incorrect. This may result in the menu governor making
wrong state decisions.

Merge tag 'uapi-fixes-20121017' of git://git.infradead.org/users/dhowells/linux-headers

Pull misc UAPI fixes from David Howells:
 "They do a number of things:

  (1) Import a patch from Catalin Marinas to extend the generic-y in
      Kbuild facility to uapi directories.

  (2) Make arch/tile's ucontext.h file use (1) and remove the header-y
      line from the kernel internal side of things.

  (3) Remove some now-empty conditional bits from include/linux/Kbuild.
      The contents got moved to the UAPI side of things along with new
      conditionals.

  (4) Deal with now-empty files:

     (a) Empty Kbuild files under include/ get removed.

     (b) Empty Kbuild files under arch/ get comments to hold them as
         they are likely to end up with generic-y or genhdr-y lines.
         Deleting them appears to work if we want to go that route.

     (c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the
         patch program from deleting that, and made the arches with
         empty kvm_para.h uapi files use that instead of having their
         own files.

     (d) Put comments into four other empty uapi/ headers to prevent the
         patch program from deleting them.

  A question: Is this the right way to deal with the now-empty Kbuild
  files?

  The ones under include/ are unlikely to be used - even for generated
  files, I think - so getting rid of them is probably okay.  Once all
  the bits are in, we can probably remove all the Kbuild files under
  include/ that aren't also under include/uapi/.

  The ones under arch/ are more of an issue because of the potential for
  generic-y and genhdr-y."

This option is a merge of both analog TV and DVB CUSTOMISE.

At the merge, the dependencies were not done right: the menu
currently appears only for analog TV. It should also be opened
for digital TV. As there are other I2C devices there (flash
devices, etc) that aren't related to either one, it is better
to make it generic enough to open for all media devices with

Possibly they should be just deleted, but it's possible that they'll acquire

David Howells [Wed, 17 Oct 2012 11:31:15 +0000]
UAPI: Remove empty non-UAPI Kbuild files

Remove non-UAPI Kbuild files that have become empty as a result of UAPI
disintegration.  They used to have only header-y lines in them and those have
now moved to the Kbuild files in the corresponding uapi/ directories.

Possibly these should not be removed but rather have a comment inserted to say
they are intentionally left blank.  This would make it easier to add generated
header lines in future without having to restore the infrastructure.

Note that at this point not all the UAPI disintegration parts have been merged,
so it is likely that more empty Kbuild files will turn up.

It is probably necessary to make the files non-empty to prevent the patch
program from automatically deleting them when it reduces them to nothing.

FRV: Fix linux/elf-fdpic.h

It seems I accidentally switched the guard on linux/elf-fdpic.h from #ifdef
__KERNEL__ to #ifndef __KERNEL__ when attempting to expand the guarded region
to cover the elf_fdpic_params struct when doing the UAPI split - with the
result that the struct became unavailable to kernel code.

Move incorrectly guarded bits back to the kernelspace header.

Whilst we're at it, the __KERNEL__ guards can be deleted as they're no longer
necessary.

7 years agomm, mempolicy: fix printing stack contents in numa_maps
David Rientjes [Wed, 17 Oct 2012 00:31:23 +0000]
mm, mempolicy: fix printing stack contents in numa_maps

When reading /proc/pid/numa_maps, it's possible to return the contents of
the stack where the mempolicy string should be printed if the policy gets
freed from beneath us.

This happens because mpol_to_str() may return an error the
stack-allocated buffer is then printed without ever being stored.

There are two possible error conditions in mpol_to_str():

 - if the buffer allocated is insufficient for the string to be stored,
   and

 - if the mempolicy has an invalid mode.

The first error condition is not triggered in any of the callers to
mpol_to_str(): at least 50 bytes is always allocated on the stack and this
is sufficient for the string to be written.  A future patch should convert
this into BUILD_BUG_ON() since we know the maximum strlen possible, but
that's not -rc material.

The second error condition is possible if a race occurs in dropping a
reference to a task's mempolicy causing it to be freed during the read().
The slab poison value is then used for the mode and mpol_to_str() returns
-EINVAL.

This race is only possible because get_vma_policy() believes that
mm->mmap_sem protects task->mempolicy, which isn't true.  The exit path
does not hold mm->mmap_sem when dropping the reference or setting
task->mempolicy to NULL: it uses task_lock(task) instead.

Thus, it's required for the caller of a task mempolicy to hold
task_lock(task) while grabbing the mempolicy and reading it.  Callers with
a vma policy store their mempolicy earlier and can simply increment the
reference count so it's guaranteed not to be freed.

MIPS: Make __{,n,u}delay declarations match definitions and generic delay.h

At some recent point arch/mips/include/asm/delay.h has started being
included into csrc-octeon.c where the __?delay() functions are defined.
This causes a compile failure due to conflicting declarations and
definitions of the functions.

It turns out that the generic definitions in arch/mips/lib/delay.c also
conflict.

Proposed fix: Declare the functions to take unsigned long parameters
just like asm-generic (and x86) does.  Update __delay to agree
(__ndelay and __udelay need no change).

Bonus: Get rid of 'inline' from __delay() definition, as it is globally
visible, and the compiler should be making this decision itself (it does
in fact inline the function without being told to).

sparc64: Fix bit twiddling in sparc_pmu_enable_event().

There was a serious disconnect in the logic happening in
sparc_pmu_disable_event() vs. sparc_pmu_enable_event().

Event disable is implemented by programming a NOP event into the PCR.

However, event enable was not reversing this operation.  Instead, it
was setting the User/Priv/Hypervisor trace enable bits.

That's not sparc_pmu_enable_event()'s job, that's what
sparc_pmu_enable() and sparc_pmu_disable() do .

The intent of sparc_pmu_enable_event() is clear, since it first clear
out the event type encoding field.  So fix this by OR'ing in the event
encoding rather than the trace enable bits.

7 years agoqeth: fix deadlock between recovery and bonding driver
Stefan Raspl [Mon, 15 Oct 2012 19:21:18 +0000]
qeth: fix deadlock between recovery and bonding driver

The recovery thread, when failing, tears down the respective interface. To do
so, it needs to obtain the rtnl lock first, as the interface configuration is
changed.
If another process tries to modify an interface setting at the same time, that
process can obtain the rtnl lock first, but the respective callback in the qeth
driver will block until recovery has completed - which cannot happen since the
calling process already obtained it.
In one particular case, the bonding driver acquired the rtnl lock to modify the
card's MAC address, while the recovery failed at the same time due to the card
being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock)
was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock.
This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the
lock cannot be obtained, the interface will be left up, but the card state
remains in CARD_STATE_RECOVER, which will prevent any further activities on the
card.

This return was stupid to begin with since it may have left the card

function is only defined for CONFIG_CPU_FREQ_TABLE resulting in the

Fix it by selecting CONFIG_CPU_FREQ_TABLE for such a configuration.
