Pull USB fixes from Greg KH:
"Here are a bunch of USB fixes for 3.13-rc3.
Nothing major, but we seem to have an argument about a XHCI fix, so
I'm not including a revert that Sarah requested, because that breaks a
USB network driver, and I can't revert the USB network driver fix
without reintroducing other bugs that it fixed. So as it is,
everything should now be working. Worse case, I can revert the XHCI
fix before 3.13-final is out, but it seems to work well here with my
testing, so all should be good.
Other than that, some driver updates based on reports"

Pull x86 and EFI fixes from Peter Anvin:
"Half of these are EFI-related:
The by far biggest change is the change to hold off the deletion of a
sysfs entry while a backend scan is in progress. This is to avoid
calling kmemdup() while under a spinlock.
The other major change is for each entry in the EFI pstore backend to
get a unique identifier, as required by the pstore filesystem proper.
The other changes are:
A fix to the recent consolidation and optimization of using "asm goto"
with read-modify-write operation, which broke the bitops; specifically
in such a way that we could end up generating invalid code.
A build hack to make sure we compile with -mno-sse. icc, and most
likely future versions of gcc, can generate SSE instructions unless we
tell it not to.

When multiple wireless USB devices are connected and one of the devices
disconnects, the host will distribute a new group key to the remaining
devicese using wusbhc_gtk_rekey. wusbhc_gtk_rekey takes the
wusbhc->mutex and holds it while it submits a URB to set the new key.
This causes a deadlock in wa_urb_enqueue when it calls a device lookup
helper function that takes the same lock.
This patch changes wusbhc_gtk_rekey to submit a work item to set the GTK
so that the URB is submitted without holding wusbhc->mutex.

Section 4.11.7.1 of rev 1.0 of the xhci specification states that a link TRB
can only occur at a boundary between underlying USB frames (512 bytes for
high speed devices).
If this isn't done the USB frames aren't formatted correctly and, for example,
the USB3 ethernet ax88179_178a card will stop sending (while still receiving)
when running a netperf tcp transmit test with (say) and 8k buffer.
This should be a candidate for stable, the ax88179_178a driver defaults to
gso and tso enabled so it passes a lot of fragmented skb to the USB stack.
Notes from Sarah:
Discussion: http://marc.info/?l=linux-usb&m=138384509604981&w=2
This patch fixes a long-standing xHCI driver bug that was revealed by a
change in 3.12 in the usb-net driver. Commit
638c5115a794981441246fa8fa5d95c1875af5ba "USBNET: support DMA SG" added
support to use bulk endpoint scatter-gather (urb->sg). Only the USB
ethernet drivers trigger this bug, because the mass storage driver sends
sg list entries in page-sized chunks.
This patch only fixes the issue for bulk endpoint scatter-gather. The
problem will still occur for periodic endpoints, because hosts will
interpret no-op transfers as a request to skip a service interval, which
is not what we want.
Luckily, the USB core isn't set up for scatter-gather on isochronous
endpoints, and no USB drivers use scatter-gather for interrupt
endpoints. Document this known limitation so that developers won't try
to use urb->sg for interrupt endpoints until this issue is fixed. The
more comprehensive fix would be to allow link TRBs in the middle of the
endpoint ring and revert this patch, but that fix would touch too much
code to be allowed in for stable.
This patch should be backported to kernels as old as 3.12, that contain
the commit 638c5115a794981441246fa8fa5d95c1875af5ba "USBNET: support DMA
SG". Without this patch, the USB network device gets wedged, and stops
sending packets. Mark Lord confirms this patch fixes the regression:

Pull networking updates from David Miller:
"Here is a pile of bug fixes that accumulated while I was in Europe"
1) In fixing kernel leaks to userspace during copying of socket
addresses, we broke a case that used to work, namely the user
providing a buffer larger than the in-kernel generic socket address
structure. This broke Ruby amongst other things. Fix from Dan
Carpenter.
2) Fix regression added by byte queue limit support in 8139cp driver,
from Yang Yingliang.
3) The addition of MSG_SENDPAGE_NOTLAST buggered up a few sendpage
implementations, they should just treat it the same as MSG_MORE.
Fix from Richard Weinberger and Shawn Landden.
4) Handle icmpv4 errors received on ipv6 SIT tunnels correctly, from
Oussama Ghorbel. In particular we should send an ICMPv6 unreachable
in such situations.
5) Fix some regressions in the recent genetlink fixes, in particular
get the pmcraid driver to use the new safer interfaces correctly.

Some host adapters do not pass commands through to the target disk
directly. Instead they provide an emulated target which may or may not
accurately report its capabilities. In some cases the physical device
characteristics are reported even when the host adapter is processing
commands on the device's behalf. This can lead to adapter firmware hangs
or excessive I/O errors.
This patch disables WRITE SAME for devices connected to host adapters
that provide an emulated target. Driver writers can disable WRITE SAME
by setting the no_write_same flag in the host adapter template.

Currently retransmitted DATA chunks could also be used for

the transmitted DATA chunk is a new one or a retransmitted one.
This problem is introduced by commit ae19c5486 ("sctp: remove
'resent' bit from the chunk") which inappropriately removed the
'resent' bit completely, instead of doing this, we should set
the resent bit only for the retransmitted DATA chunks.

The pmcraid driver is abusing the genetlink API and is using its
family ID as the multicast group ID, which is invalid and may
belong to somebody else (and likely will.)
Make it use the correct API, but since this may already be used
as-is by userspace, reserve a family ID for this code and also
reserve that group ID to not break userspace assumptions.
My previous patch broke event delivery in the driver as I missed
that it wasn't using the right API and forgot to update it later
in my series.
While changing this, I noticed that the genetlink code could use
the static group ID instead of a strcmp(), so also do that for
the VFS_DQUOT family.

The first netlink attribute (value 0) must always be defined as none/unspec.
This is correctly done in inet_diag.h, but other diag interfaces are wrong.
Because we cannot change an existing API, I add a comment to point the mistake
and avoid to propagate it in a new diag API in the future.

completed
Currently, when mounting pstore file system, a read callback of
efi_pstore driver runs mutiple times as below.
- In the first read callback, scan efivar_sysfs_list from head and pass
a kmsg buffer of a entry to an upper pstore layer.
- In the second read callback, rescan efivar_sysfs_list from the entry
and pass another kmsg buffer to it.
- Repeat the scan and pass until the end of efivar_sysfs_list.
In this process, an entry is read across the multiple read function
calls. To avoid race between the read and erasion, the whole process
above is protected by a spinlock, holding in open() and releasing in
close().
At the same time, kmemdup() is called to pass the buffer to pstore
filesystem during it. And then, it causes a following lockdep warning.
To make the dynamic memory allocation runnable without taking spinlock,
holding off a deletion of sysfs entry if it happens while scanning it
via efi_pstore, and deleting it after the scan is completed.
To implement it, this patch introduces two flags, scanning and deleting,
to efivar_entry.
On the code basis, it seems that all the scanning and deleting logic is
not needed because __efivars->lock are not dropped when reading from the
EFI variable store.
But, the scanning and deleting logic is still needed because an
efi-pstore and a pstore filesystem works as follows.
In case an entry(A) is found, the pointer is saved to psi->data. And
efi_pstore_read() passes the entry(A) to a pstore filesystem by
releasing __efivars->lock.
And then, the pstore filesystem calls efi_pstore_read() again and the
same entry(A), which is saved to psi->data, is used for resuming to scan
a sysfs-list.
So, to protect the entry(A), the logic is needed.

The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain
function to chain two scatterlists, but the chain pointer indication
bit is not set. When the resulting scatterlist is used, for example,
by sg_nents to count the number of scatterlist entries, a segfault occurs
because sg_nents does not follow the chain pointer to the chained scatterlist.
Update scatterwalk_sg_chain to set the chain pointer indication bit as is
done by the sg_chain function.

This patch adds cpufreq suspend/resume calls to dpm_{suspend|resume}_noirq()
for handling suspend/resume of cpufreq governors.
Lan Tianyu (Intel) & Jinhyuk Choi (Broadcom) found anr issue where
tunables configuration for clusters/sockets with non-boot CPUs was
getting lost after suspend/resume, as we were notifying governors
with CPUFREQ_GOV_POLICY_EXIT on removal of the last cpu for that
policy and so deallocating memory for tunables. This is fixed by
this patch as we don't allow any operation on governors after
device suspend and before device resume now.

Avoid declaring ALIGN() and __aligned() in

namespace. Also, mic_aligned_size() can be simply replaced simply by
sizeof() since all structures where mic_aligned_size() is used are
declared using __attribute__ ((aligned(8)));

This puts two macros, ALIGN() and __aligned(), into arbitrary user space

When these structures are forced-aligned, they will in fact have padding
automatically added by the compiler to an 8-byte boundary anyway, so
mic_aligned_size() does nothing.

1) is a bug fix that happens when root does the following:

after that.
2) if a TRACE_EVENT has a string field, and NULL is given for it.
The internal trace event code does a strlen() and strcpy() on the

New tracepoints have been added that have allowed for NULL pointers
being assigned to strings. To fix this, change the TRACE_EVENT() code

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.

GPIO mapping properties were defined using the GPIOF_* flags, which are
declared in linux/gpio.h. This file is not included when using the
GPIO descriptor interface.
This patch declares the flags that can be used as GPIO mappings
properties in linux/gpio/driver.h, and uses them in gpiolib, so that no
deprecated declarations are used by the GPIO descriptor interface.
This patch also allows GPIO_OPEN_DRAIN and GPIO_OPEN_SOURCE to be
specified as GPIO mapping properties.

Commit bceaa90240b6019ed73b49965eac7d167610be69 ("inet: prevent leakage
of uninitialized memory to user in recv syscalls") conditionally updated
addr_len if the msg_name is written to. The recv_error and rxpmtu
functions relied on the recvmsg functions to set up addr_len before.
As this does not happen any more we have to pass addr_len to those
functions as well and set it to the size of the corresponding sockaddr
length.

Pull DRM fixes from Dave Airlie:
"I was going to leave this until post -rc1 but sysfs fixes broke
hotplug in userspace, so I had to fix it harder, otherwise a set of
pulls from intel, radeon and vmware,
The vmware/ttm changes are bit larger but since its early and they are
unlikely to break anything else I put them in, it lets vmware work
with dri3"

Pull networking fixes from David Miller:
1) Fix memory leaks and other issues in mwifiex driver, from Amitkumar
Karwar.
2) skb_segment() can choke on packets using frag lists, fix from
Herbert Xu with help from Eric Dumazet and others.
3) IPv4 output cached route instantiation properly handles races
involving two threads trying to install the same route, but we
forgot to propagate this logic to input routes as well. Fix from
Alexei Starovoitov.
4) Put protections in place to make sure that recvmsg() paths never
accidently copy uninitialized memory back into userspace and also
make sure that we never try to use more that sockaddr_storage for
building the on-kernel-stack copy of a sockaddr. Fixes from Hannes
Frederic Sowa.
5) R8152 driver transmit flow bug fixes from Hayes Wang.
6) Fix some minor fallouts from genetlink changes, from Johannes Berg
and Michael Opdenacker.
7) AF_PACKET sendmsg path can race with netdevice unregister notifier,
fix by using RCU to make sure the network device doesn't go away
from under us. Fix from Daniel Borkmann.
