I have vehemently opposed adding a "permissive" mode to Smack
for the simple reasons that it would be subject to massive abuse
and that developers refuse to turn it off come product release.
I still believe that this is true, and still refuse to add a
general "permissive mode". So don't ask again.
Bumjin Im suggested an approach that addresses most of the concerns,
and I have implemented it here. I still believe that we'd be better
off without this sort of thing, but it looks like this minimizes the
abuse potential.
Firstly, you have to configure Smack Bringup Mode. That allows
for "release" software to be ammune from abuse. Second, only one
label gets to be "permissive" at a time. You can use it for
debugging, but that's about it.
A label written to smackfs/unconfined is treated specially.
If either the subject or object label of an access check
matches the "unconfined" label, and the access would not
have been allowed otherwise an audit record and a console
message are generated. The audit record "request" string is
marked with either "(US)" or "(UO)", to indicate that the
request was granted because of an unconfined label. The
fact that an inode was accessed by an unconfined label is
remembered, and subsequent accesses to that "impure"
object are noted in the log. The impurity is not stored in
the filesystem, so a file mislabled as a side effect of
using an unconfined label may still cause concern after
a reboot.
So, it's there, it's dangerous, but so many application
developers seem incapable of living without it I have
given in. I've tried to make it as safe as I can, but
in the end it's still a chain saw.

This change fixes the bug associated with sockets owned by kernel threads. These
sockets, created usually by network devices' drivers tasks, received smk_in
label from the task that created them - the "floor" label in the most cases. The
result was that they were not able to receive data packets because of missing
smack rules. The main reason of the access deny is that the socket smk_in label
is placed as the object during smk check, kernel thread's capabilities are
omitted.

Make the tpm_infineon driver define its PM callbacks through
a struct dev_pm_ops object rather than by using legacy PM hooks
in struct pnp_driver.
This allows the driver to use tpm_pm_suspend() as its suspend

tpm_i2c_stm_st33 is a TIS 1.2 TPM with a core interface which can be used
by different phy such as i2c or spi. The core part is called st33zp24 which
is also the main part reference.
include/linux/platform_data/tpm_stm_st33.h is renamed consequently.
The driver is also split into an i2c phy in charge of sending/receiving

I started to work with PPI interface so that it would be available
under character device sysfs directory and realized that chip
registeration was still too messy.
In TPM 1.x in some rare scenarios (errors that almost never occur)
wrong order in deinitialization steps was taken in teardown. I
reproduced these scenarios by manually inserting error codes in the
place of the corresponding function calls.
The key problem is that the teardown is messy with two separate code
paths (this was inherited when moving code from tpm-interface.c).
Moved TPM 1.x specific register/unregister functionality to own helper
functions and added single code path for teardown in tpm_chip_register().
Now the code paths have been fixed and it should be easier to review
later on this part of the code.

Problem: When IMA and VTPM are both enabled in kernel config,
kernel hangs during bootup on LE OS.
Why?: IMA calls tpm_pcr_read() which results in tpm_ibmvtpm_send
and tpm_ibmtpm_recv getting called. A trace showed that
tpm_ibmtpm_recv was hanging.
Resolution: tpm_ibmtpm_recv was hanging because tpm_ibmvtpm_send
was sending CRQ message that probably did not make much sense
to phype because of Endianness. The fix below sends correctly
converted CRQ for LE. This was not caught before because it
seems IMA is not enabled by default in kernel config and
IMA exercises this particular code path in vtpm.
Tested with IMA and VTPM enabled in kernel config and VTPM
enabled on both a BE OS and a LE OS ppc64 lpar. This exercised
CRQ and TPM command code paths in vtpm.
Patch is against Peter's tpmdd tree on github which included
Vicky's previous vtpm le patches.

.. after extensive statistical analysis of my G+ polling, I've come to
the inescapable conclusion that internet polls are bad.
Big surprise.
But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
margin, in a poll that people weren't even supposed to participate in.
Who can argue with solid numbers like that? 5,796 votes from people who
can't even follow the most basic directions?
In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
but with a total of 29,110 votes right now.
Now, arguably, that vote spread is only about 3,200 votes, which is less
than the almost six thousand votes that the "please ignore" poll got, so
it could be considered noise.
But hey, I asked, so I'll honor the votes.

I've noticed significant locking contention in memory reclaimer around
sb_lock inside grab_super_passive(). Grab_super_passive() is called from
two places: in icache/dcache shrinkers (function super_cache_scan) and
from writeback (function __writeback_inodes_wb). Both are required for
progress in memory allocator.
Grab_super_passive() acquires sb_lock to increment sb->s_count and check
sb->s_instances. It seems sb->s_umount locked for read is enough here:
super-block deactivation always runs under sb->s_umount locked for write.
Protecting super-block itself isn't a problem: in super_cache_scan() sb
is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers
are still active. Inside writeback super-block comes from inode from bdi
writeback list under wb->list_lock.
This patch removes locking sb_lock and checks s_instances under s_umount:
generic_shutdown_super() unlinks it under sb->s_umount locked for write.
New variant is called trylock_super() and since it only locks semaphore,
callers must call up_read(&sb->s_umount) instead of drop_super(sb) when
they're done.

Convert the following where appropriate:
(1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry).
(2) S_ISREG(dentry->d_inode) to d_is_reg(dentry).
(3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry). This is actually more
complicated than it appears as some calls should be converted to
d_can_lookup() instead. The difference is whether the directory in
question is a real dir with a ->lookup op or whether it's a fake dir with
a ->d_automount op.
In some circumstances, we can subsume checks for dentry->d_inode not being
NULL into this, provided we the code isn't in a filesystem that expects
d_inode to be NULL if the dirent really *is* negative (ie. if we're going to
use d_inode() rather than d_backing_inode() to get the inode pointer).
Note that the dentry type field may be set to something other than
DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS
manages the fall-through from a negative dentry to a lower layer. In such a
case, the dentry type of the negative union dentry is set to the same as the
type of the lower dentry.
However, if you know d_inode is not NULL at the call site, then you can use
the d_is_xxx() functions even in a filesystem.
There is one further complication: a 0,0 chardev dentry may be labelled
DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE. Strictly, this was
intended for special directory entry types that don't have attached inodes.
The following perl+coccinelle script was used:
use strict;
my @callers;

Introduce some function for getting the inode (and also the dentry) in an
environment where layered/unioned filesystems are in operation.
The problem is that we have places where we need *both* the union dentry and
the lower source or workspace inode or dentry available, but we can only have
a handle on one of them. Therefore we need to derive the handle to the other
from that.
The idea is to introduce an extra field in struct dentry that allows the union
dentry to refer to and pin the lower dentry.

Pull xfs pnfs block layout support from Dave Chinner:
"This contains the changes to XFS needed to support the PNFS block
layout server that you pulled in through Bruce's NFS server tree
merge.
I originally thought that I'd need to merge changes into the NFS
server side, but Bruce had already picked them up and so this is
purely changes to the fs/xfs/ codebase.
Summary:
This update contains the implementation of the PNFS server export
methods that enable use of XFS filesystems as a block layout target"

Pull one more batch of power management and ACPI updates from Rafael Wysocki:
"These are mostly fixes on top of the previously merged recent PM and
ACPI material.
First, one commit that broke the ACPI LPSS (Low-Power Subsystem)
driver on a Dell box is reverted and there are two stable-candidate
fixes for that driver. Another fix cleans up two recently added ACPI
EC messages that look odd and the printk level of a noisy debug
message in the core ACPI resources handling code is reduced.
In addition to that we have two stable-candidate fixes for the s3c
cpufreq driver, two cpuidle powernv driver updates related to Device
Trees and a PNP subsystem cleanup that will allow us to get rid of
some old ugliness going forward. Also there is a new blacklist entry
for the ACPI backlight code.
Specifics:
- Revert a recent ACPI LPSS driver commit that prevented the touchpad
driver from loading on Dell XPS13 (Jarkko Nikula).
- Make the ACPI LPSS driver disable the I2C controllers and deassert
SPI host controllers resets at startup on Intel BayTrail and
Braswell SoCs in case they have been left in wrong states by the
platform firmware which then may casuse fatal controller driver
failures during resume from hibernation (Mika Westerberg).
- Make two recently added ACPI EC messages look better (Scot Doyle).
- Reduce the printk level of a recently added debug message related
to ACPI resources that may become noisy in some cases (Rafael J
Wysocki).
- Add a new ACPI backlight blacklist entry for Samsung Series 9
(900X3C/900X3D/900X3E/900X4C/900X4D) laptops where the native
backlight interface doesn't work while the ACPI based one does
(Jens Reyer).
- Make the PNP sybsystem's core code use __request_region() followed
by __release_region() instead of __check_region() which then will
allow us to get rid of the latter as it has no more users (Jakub
Sitnicki).
- Fix a build breakage and an issue with two __init functions that
may be called after initialization in the s3c cpufreq driver (Arnd
Bergmann).
- Make the powernv cpuidle driver read target_residency values for
idle states from a Device Tree (as we have the suitable DT bindings
for that now) and improve the parsing of the powermgmt DT node in
that driver (Preeti U Murthy)"
* tag 'pm+acpi-3.20-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpuidle: powernv: Avoid endianness conversions while parsing DT

ACPI / LPSS: Always disable I2C host controllers
ACPI / resources: Change pr_info() to pr_debug() for debug information
ACPI / video: Disable native backlight on Samsung Series 9 laptops
cpuidle: powernv: Read target_residency value of idle states from DT if available
Revert "ACPI / LPSS: Remove non-existing clock control from Intel Lynxpoint I2C"
ACPI / EC: Remove non-standard log emphasis
PNP: Switch from __check_region() to __request_region()
