Linux 3.14-rc6

Nothing prevents GPIO drivers from returning values outside the
boolean range, and as it turns out a few drivers are actually doing so.
These values were passed as-is to unsuspecting consumers and created
confusion.

This patch makes the internal _gpiod_get_raw_value() function return a
bool, effectively clamping the GPIO value to the boolean range no
matter what the driver does.

While we are at it, we also change the value parameter of
_gpiod_set_raw_value() to bool type before drivers start doing funny
things with it as well.

Another way to fix this would be to change the prototypes of the driver
interface to use bool directly, but this would require a huge
cross-systems patch so this simpler solution is preferred.

Changes since v1:
- Change local variable type to bool as well, use boolean values in
  code
- Also change prototype of open drain/open source setting functions
  since they are only called from _gpiod_set_raw_value()

This probably calls for a larger booleanization of gpiolib, but let's
keep that for a latter change - right now we need to address the issue
of non-boolean values returned by drivers.

The current ACPI GPIO event handling code was never tested against real
hardware with functioning GPIO triggered events (at the time such hardware
wasn't available). Thus it misses certain things like requesting the GPIOs
properly, passing correct flags to the interrupt handler and so on.

This patch reworks ACPI GPIO event handling so that we:

 1) Use struct acpi_gpio_event for all GPIO signaled events.
 2) Switch to use GPIO descriptor API and request GPIOs by calling
    gpiochip_request_own_desc() that we added in a previous patch.
 3) Pass proper flags from ACPI GPIO resource to request_threaded_irq().

Also instead of open-coding the _AEI iteration loop we can use
acpi_walk_resources(). This simplifies the code a bit and fixes memory leak
that was caused by missing kfree() for buffer returned by
acpi_get_event_resources().

Since the remove path now calls gpiochip_free_own_desc() which takes GPIO
spinlock we need to call acpi_gpiochip_remove() outside of that lock
(analogous to acpi_gpiochip_add() path where the lock is released before
those funtions are called).

We are going to add more ACPI specific data to accompany GPIO chip so
instead of allocating it per each use-case we allocate it once when
acpi_gpiochip_add() is called and release it when acpi_gpiochip_remove() is
called.

Doing this allows us to add more ACPI specific data by merely adding new
fields to struct acpi_gpio_chip.

In addition we embed evt_pins member directly to the structure instead of
having it as a pointer. This simplifies the code a bit since we don't need
to check against NULL.

Sometimes it is useful to allow GPIO chips themselves to request GPIOs they
own through gpiolib API. One use case is ACPI ASL code that should be able
to toggle GPIOs through GPIO operation regions.

We can't use gpio_request() because it will pin the module to the kernel
forever (it calls try_module_get()). To solve this we move module refcount
manipulation to gpiod_request() and let __gpiod_request() handle the actual
request. This changes the sequence a bit as now try_module_get() is called
outside of gpio_lock (I think this is safe, try_module_get() handles
serialization it needs already).

Then we provide gpiolib internal functions gpiochip_request/free_own_desc()
that do the same as gpio_request() but don't manipulate module refrence
count. This allows the GPIO chip driver to request and free descriptors it
owns without being pinned to the kernel forever.

For certain irq types, e.g. gpios, it's necessary to request resources
before starting up the irq.

This might fail so we cannot use the irq_startup() callback because we
might call the irq_set_type() callback before that which does not make
sense when the resource is not available. Calling irq_startup() before
irq_set_type() can lead to spurious interrupts which is not desired
either.

  staging/cxt1e1/linux.c: Correct arbitrary memory write in c4_ioctl()

This fixes CVE-2014-0102.

The following command sequence produces an oops:

	keyctl new_session
	i=`keyctl newring _ses @s`
	keyctl link @s $i

The problem is that search_nested_keyrings() sees two keyrings that have
matching type and description, so keyring_compare_object() returns true.
s_n_k() then passes the key to the iterator function -
keyring_detect_cycle_iterator() - which *should* check to see whether this is
the keyring of interest, not just one with the same name.

Because assoc_array_find() will return one and only one match, I assumed that
the iterator function would only see an exact match or never be called - but
the iterator isn't only called from assoc_array_find()...

The oops looks something like this:

	kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003!
	invalid opcode: 0000 [#1] SMP
	...
	RIP: keyring_detect_cycle_iterator+0xe/0x1f

	  keyctl_keyring_link+0x60/0x81
	  SyS_keyctl+0x65/0xe4
	  tracesys+0xdd/0xe2

The fix is to make keyring_detect_cycle_iterator() check that the key it
has is the key it was actually looking for rather than calling BUG_ON().

A testcase has been included in the keyutils testsuite for this:

  modules to be loaded, then when one is, the kernel will silently set
  the MODULE_FORCED taint on the module.  Although, this taint happens
  without the need for insmod --force or anything of the kind, it labels
  the module with that taint anyway.

  If this tainted module has tracepoints, the tracepoints will be
  ignored because of the MODULE_FORCED taint.  But no error message will
  be displayed.  Worse yet, the event infrastructure will still be
  created letting users enable the trace event represented by the
  tracepoint, although that event will never actually be enabled.  This
  is because the tracepoint infrastructure allows for non-existing
  tracepoints to be enabled for new modules to arrive and have their
  tracepoints set.

  Although there are several things wrong with the above, this change
  only addresses the creation of the trace event files for tracepoints
  that are not created when a module is loaded and is tainted.  This
  change will print an error message about the module being tainted and
  not the trace events will not be created, and it does not create the
  trace event infrastructure"
