In the original HID sensor hub firmwares all Named array enums were
to 0-based. But the most recent hub implemented as 1-based,
because of the implementation by one of the major OS vendor.
Using logical minimum for the field as the base of enum. So we add
logical minimum to the selector values before setting those fields.
Some sensor hub FWs already changed logical minimum from 0 to 1
to reflect this and hope every other vendor will follow.
There is no easy way to add a common HID quirk for NAry elements,
even if the standard specifies these field as NAry, the collection
used to describe selectors is still just "logical".

There seems to be no active maintainer for the driver, and there is an
unfixed security bug, so disable the driver for now.
Hopefully someone steps up to be the maintainer, and works to get this
out of staging, otherwise it will be deleted soon.

zsmalloc encodes a handle using the pfn and an object
index. On hardware platforms with physical memory starting
at 0x0 the pfn can be 0. This causes the encoded handle to be
0 and is incorrectly interpreted as an allocation failure.
This issue affects all current and future SoCs with physical
memory starting at 0x0. All MSM8974 SoCs which includes
Google Nexus 5 devices are affected.
To prevent this false error we ensure that the encoded handle
will not be 0 when allocation succeeds.

Jonathan writes:
First round of fixes for IIO in the 3.13 cycle.
The usual mixed bag of fixes.
* 3 cases where kconfig dependencies were missing. We need to keep a closer
eye on this in new drivers.
* hid_sensors was abusing the iio_dev->trigger pointer. We had a round
of clearing this out some time ago but this driver clearly slipped through.
* A misuse of the IIO_ST macro, in mcp3422, which we should really make a
concertive effort to finish removing.
* Avoid a double free introduced by recent buffer reference counting in the
one driver that (quite reasonably!) does things differently (am335x)
* A missing mutex_unlock in kxsd9 that means that driver has been non
functional for some time and no one noticed (including me who for once
actually has one of the supported devices).
* An incorrect assumption about the parameters of sign_extend32 in mcp3422.
So nothing controversial. The only substantial patch is the hid_sensors
one and that is actually just adding a new pointer to the devices private
state then moving the code over to it.

commit b8d181e408af (staging: drm/imx: add drm plane support) added a file
to the make target for DRM_IMX_IPUV3 but didn't adjust the objs required
to actually build that as a module. Kbuild got confused and this lead to
link errors like:
ERROR: "ipu_plane_disable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!
ERROR: "ipu_plane_enable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!
Additionally, it added a call to imx_drm_crtc_id which also fails with a
link error as above. To fix this, we adjust the make target with the proper
objs, which will change the name of the resulting .ko. We also add an
EXPORT_SYMBOL_GPL for imx_drm_crtc_id.

I broke `s626_set_dac()` by changing the type of the `dacdata` parameter
from `short` to `unsigned short`. It's actually designed to take a
signed value in the range -0x1fff to +0x2000 although values above
0x1fff get clamped to 0x1fff. (We could change the `maxdata` value to
0x1ffe to avoid the clamping, but `maxdata` values are usually a power
of 2 minus 1.) The bug results in all negative values passed to the
function being changed to +0x1fff by the clamp. Change the parameter
type to `int16_t` to fix the problem.

Pull security subsystem updates from James Morris:
"In this patchset, we finally get an SELinux update, with Paul Moore
taking over as maintainer of that code.
Also a significant update for the Keys subsystem, as well as
maintenance updates to Smack, IMA, TPM, and Apparmor"
and since I wanted to know more about the updates to key handling,
here's the explanation from David Howells on that:
"Okay. There are a number of separate bits. I'll go over the big bits
and the odd important other bit, most of the smaller bits are just
fixes and cleanups. If you want the small bits accounting for, I can
do that too.
(1) Keyring capacity expansion.
KEYS: Consolidate the concept of an 'index key' for key access
KEYS: Introduce a search context structure
KEYS: Search for auth-key by name rather than target key ID
Add a generic associative array implementation.
KEYS: Expand the capacity of a keyring
Several of the patches are providing an expansion of the capacity of a
keyring. Currently, the maximum size of a keyring payload is one page.
Subtract a small header and then divide up into pointers, that only gives
you ~500 pointers on an x86_64 box. However, since the NFS idmapper uses
a keyring to store ID mapping data, that has proven to be insufficient to
the cause.
Whatever data structure I use to handle the keyring payload, it can only
store pointers to keys, not the keys themselves because several keyrings
may point to a single key. This precludes inserting, say, and rb_node
struct into the key struct for this purpose.
I could make an rbtree of records such that each record has an rb_node
and a key pointer, but that would use four words of space per key stored
in the keyring. It would, however, be able to use much existing code.
I selected instead a non-rebalancing radix-tree type approach as that
could have a better space-used/key-pointer ratio. I could have used the
radix tree implementation that we already have and insert keys into it by
their serial numbers, but that means any sort of search must iterate over
the whole radix tree. Further, its nodes are a bit on the capacious side
for what I want - especially given that key serial numbers are randomly
allocated, thus leaving a lot of empty space in the tree.
So what I have is an associative array that internally is a radix-tree
with 16 pointers per node where the index key is constructed from the key
type pointer and the key description. This means that an exact lookup by
type+description is very fast as this tells us how to navigate directly to
the target key.
I made the data structure general in lib/assoc_array.c as far as it is
concerned, its index key is just a sequence of bits that leads to a
pointer. It's possible that someone else will be able to make use of it
also. FS-Cache might, for example.
(2) Mark keys as 'trusted' and keyrings as 'trusted only'.
KEYS: verify a certificate is signed by a 'trusted' key
KEYS: Make the system 'trusted' keyring viewable by userspace
KEYS: Add a 'trusted' flag and a 'trusted only' flag
KEYS: Separate the kernel signature checking keyring from module signing
These patches allow keys carrying asymmetric public keys to be marked as
being 'trusted' and allow keyrings to be marked as only permitting the
addition or linkage of trusted keys.
Keys loaded from hardware during kernel boot or compiled into the kernel
during build are marked as being trusted automatically. New keys can be
loaded at runtime with add_key(). They are checked against the system
keyring contents and if their signatures can be validated with keys that
are already marked trusted, then they are marked trusted also and can
thus be added into the master keyring.
Patches from Mimi Zohar make this usable with the IMA keyrings also.
(3) Remove the date checks on the key used to validate a module signature.
X.509: Remove certificate date checks
It's not reasonable to reject a signature just because the key that it was
generated with is no longer valid datewise - especially if the kernel
hasn't yet managed to set the system clock when the first module is
loaded - so just remove those checks.
(4) Make it simpler to deal with additional X.509 being loaded into the kernel.
KEYS: Load *.x509 files into kernel keyring
KEYS: Have make canonicalise the paths of the X.509 certs better to deduplicate
The builder of the kernel now just places files with the extension ".x509"
into the kernel source or build trees and they're concatenated by the
kernel build and stuffed into the appropriate section.
(5) Add support for userspace kerberos to use keyrings.
KEYS: Add per-user_namespace registers for persistent per-UID kerberos caches
KEYS: Implement a big key type that can save to tmpfs
Fedora went to, by default, storing kerberos tickets and tokens in tmpfs.
We looked at storing it in keyrings instead as that confers certain
advantages such as tickets being automatically deleted after a certain
amount of time and the ability for the kernel to get at these tokens more
easily.
To make this work, two things were needed:
(a) A way for the tickets to persist beyond the lifetime of all a user's
sessions so that cron-driven processes can still use them.
The problem is that a user's session keyrings are deleted when the
session that spawned them logs out and the user's user keyring is
deleted when the UID is deleted (typically when the last log out
happens), so neither of these places is suitable.
I've added a system keyring into which a 'persistent' keyring is
created for each UID on request. Each time a user requests their
persistent keyring, the expiry time on it is set anew. If the user
doesn't ask for it for, say, three days, the keyring is automatically
expired and garbage collected using the existing gc. All the kerberos
tokens it held are then also gc'd.
(b) A key type that can hold really big tickets (up to 1MB in size).
The problem is that Active Directory can return huge tickets with lots
of auxiliary data attached. We don't, however, want to eat up huge
tracts of unswappable kernel space for this, so if the ticket is
greater than a certain size, we create a swappable shmem file and dump
the contents in there and just live with the fact we then have an
inode and a dentry overhead. If the ticket is smaller than that, we
slap it in a kmalloc()'d buffer"

As the RTC is generally powered by backup power (VDDBU), its interrupts
are not disabled on wake-up, user, watchdog or software reset. This
could cause troubles on other systems (e.g. older kernels) if an
interrupt occurs before a handler has been installed at next boot.
Let us be well-behaved and disable them on clean shutdowns at least (as
do the RTT-based rtc-at91sam9 driver).

The lifetime changes introduced in 5bdebb183c9702a8c57a01dff09337be3de337a6
tried to use device_create, however that led to the regression where dev->type
wasn't getting set correctly. First attempt at fixing it would have led to
a race, so this undoes the device_createa work and does it all manually
making sure the dev->type is setup before we register the device.

Just a small pile of fixes for bugs and a few regressions. I'm still
trying to track down a driver load hang on my g33 (which infuriatingly
doesn't happen when loading the module manually after boot), somehow
bisecting loves to go astray on this one :( And there's a (harmless)
locking WARN in the suspend code due to one of Jesse's vlv backlight
rework patches. Otherwise nothing outstanding afaik.

In iSCSI negotiations with initiator CHAP enabled, usernames with
trailing garbage are permitted, because the string comparison only
checks the strlen of the configured username.
e.g. "usernameXXXXX" will be permitted to match "username".
Just check one more byte so the trailing null char is also matched.

This patch now always passes msg->msg_namelen as 0. recvmsg handlers must
set msg_namelen to the proper size <= sizeof(struct sockaddr_storage)
to return msg_name to the user.
This prevents numerous uninitialized memory leaks we had in the
recvmsg handlers and makes it harder for new code to accidentally leak
uninitialized memory.
Optimize for the case recvfrom is called with NULL as address. We don't
need to copy the address at all, so set it to NULL before invoking the
recvmsg handler. We can do so, because all the recvmsg handlers must
cope with the case a plain read() is called on them. read() also sets
msg_name to NULL.
Also document these changes in include/linux/net.h as suggested by David
Miller.
Changes since RFC:
Set msg->msg_name = NULL if user specified a NULL in msg_name but had a
non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't
affect sendto as it would bail out earlier while trying to copy-in the
address. It also more naturally reflects the logic by the callers of
verify_iovec.
With this change in place I could remove "
if (!uaddr || msg_sys->msg_namelen == 0)
msg->msg_name = NULL
".
This change does not alter the user visible error logic as we ignore
msg_namelen as long as msg_name is NULL.
Also remove two unnecessary curly brackets in ___sys_recvmsg and change
comments to netdev style.

The pcie_portdrv .probe() method calls pci_enable_device() once, in
pcie_port_device_register(), but the .remove() method calls
pci_disable_device() twice, in pcie_port_device_remove() and in
pcie_portdrv_remove().
That causes a "disabling already-disabled device" warning when removing a
PCIe port device. This happens all the time when removing Thunderbolt
devices, but is also easy to reproduce with, e.g.,
"echo 0000:00:1c.3 > /sys/bus/pci/drivers/pcieport/unbind"
This patch removes the disable from pcie_portdrv_remove().
