Pull security subsystem updates for 3.4 from James Morris:
"The main addition here is the new Yama security module from Kees Cook,
which was discussed at the Linux Security Summit last year. Its
purpose is to collect miscellaneous DAC security enhancements in one
place. This also marks a departure in policy for LSM modules, which
were previously limited to being standalone access control systems.
Chromium OS is using Yama, and I believe there are plans for Ubuntu,
at least.
This patchset also includes maintenance updates for AppArmor, TOMOYO
and others."
Fix trivial conflict in <net/sock.h> due to the jumo_label->static_key
rename.

This patch fixes an (ACPI S3) suspend regression introduced in commit
68d6e6713f ("tpm: Introduce function to poll for result of self test")
and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers
active.
The suspend problem occurred if the TPM was disabled and/or deactivated
and therefore the TPM_PCRRead checking the result of the (asynchronous)
self test returned an error code which then caused the tpm_tis driver to
become inactive and this then seemed to have negatively influenced the
suspend support by the tpm_infineon driver... Besides that the tpm_tis
drive may stay active even if the TPM is disabled and/or deactivated.

[The first hunk didn't make sense given one could expect

The last parameter of tpm_transmit() reflects the amount

being supplied to it. It isn't ideal to parse it directly,
so we just set it to the maximum the input buffer can handle
and let the userspace API to do such job.]

This patch introduces a function for automatic probing for the Intel iTPM
STS_DATA_EXPECT flaw.
The patch splits the current tpm_tis_send function into 2 parts where the 1st
part is now called tpm_tis_send_data() and merely sends the data to the TPM.
This function is then used for probing. The new tpm_tis_send function now
first calls tpm_tis_send_data and if that succeeds has the TPM process the
command and waits until the response is there.
The probing for the Intel iTPM is only invoked if the user has not passed
itpm=1 as parameter for the module *or* if such a TPM was detected via ACPI.
Previously it was necessary to pass itpm=1 when also passing force=1 to the
module when doing a 'modprobe'. This function is more general than the ACPI
test function and the function relying on ACPI could probably be removed.

This patch fixes several aspects of the probing for interrupts.
This patch reads the TPM's timeouts before probing for the interrupts. The
tpm_get_timeouts() function is invoked in polling mode and gets the proper
timeouts from the TPM so that we don't need to fall back to 2 minutes timeouts
for short duration commands while the interrupt probing is happening.
This patch introduces a variable probed_irq into the vendor structure that gets
the irq number if an interrupt is received while the the tpm_gen_interrupt()
function is run in polling mode during interrupt probing. Previously some
parts of tpm_gen_interrupt() were run in polling mode, then the irq variable
was set in the interrupt handler when an interrupt was received and execution
of tpm_gen_interrupt() ended up switching over to interrupt mode.
tpm_gen_interrupt() execution ended up on an event queue where it eventually
timed out since the probing handler doesn't wake any queues.
Before calling into free_irq() clear all interrupt flags that may have
been set by the TPM. The reason is that free_irq() will call into the probing
interrupt handler and may otherwise fool us into thinking that a real interrupt
happened (because we see the flags as being set) while the TPM's interrupt line
is not even connected to anything on the motherboard. This solves a problem
on one machine I did testing on (Thinkpad T60).
If a TPM claims to use a specifc interrupt, the probing is done as well
to verify that the interrupt is actually working. If a TPM indicates
that it does not use a specific interrupt (returns '0'), probe all interrupts
from 3 to 15.

This patch delays the (ACPI S3) suspend while the TPM is busy processing a
command and the TPM TIS driver is run in interrupt mode. This is the same
behavior as we already have it for the TPM TIS driver in polling mode.
Reasoning: Some of the TPM's commands advance the internal state of the TPM.
An example would be the extending of one of its PCR registers. Upper layers,
such as IMA or TSS (TrouSerS), would certainly want to be sure that the
command succeeded rather than getting an error code (-62 = -ETIME) that may
not give a conclusive answer as for what reason the command failed. Reissuing
such a command would put the TPM into the wrong state, so waiting for it to
finish is really the only option.
The downside is that some commands (key creation) can take a long time and
actually prevent the machine from entering S3 at all before the 20 second
timeout of the power management subsystem arrives.

This patch makes sure that if the TPM TIS interface is run in interrupt mode
(rather than polling mode) that all interrupts are enabled in the TPM's
interrupt enable register after a resume from ACPI S3 suspend. The registers
may either have been cleared by the TPM loosing its state during device sleep
or by the BIOS leaving the TPM in polling mode (after sending a command to
the TPM for starting it up again)
You may want to check if your TPM runs with interrupts by doing
cat /proc/interrupts | grep -i tpm
and see whether there is an entry or otherwise for it to use interrupts:
modprobe tpm_tis interrupts=1 [add 'itpm=1' for Intel TPM ]

This patch fixes the TPM's pubek sysfs entry that is accessible as long
as the TPM doesn't have an owner. It was necessary to shift the access to the
data by -10 -- the first byte immediately follows the 10 byte header. The
line
data = tpm_cmd.params.readpubek_out_buffer;
sets it at the offset '10' in the packet, so we can read the data array
starting at offset '0'.
