109571cf3e HID: i2c-hid: call the hid driver's suspend and resume callbacks
Currently, the i2c-hid driver does not call the suspend, resume, and
reset_resume callbacks in the hid_driver struct when those events occur.
This means that HID drivers for i2c-hid devices will not be able to execute
commands which may be needed during suspend or resume. One example is when a
touchpad using the hid-multitouch driver gets reset by i2c-hid coming out of
resume. Since the reset_resume callback never gets called the device is never
put back into the correct input mode. This patch calls the suspend and resume
callbacks and tries to duplicate the functionality of the usb-hid driver.

01a5f8a401 HID: rmi: change logging level of log messages related to unexpected reports
Userspace tools may use hidraw to perform operations on the device from userspace while
hid-rmi is bound to the device. This can cause hid-rmi to print error messages when its
->raw_event() callback gets called as the reports pass through the HID stack. In this case
receiving responses which were not initiated by hid-rmi is not actually an error so the resulting
error messages are incorrect and misleading. This patch changes the log messages to debug so
that the messages can be turned on in the event that there is a problem and there is not
a userspace tool running.

72c1c8179c mailbox/omap: add a parent structure for every IP instance
A new structure, omap_mbox_device, is added to contain
the global variables pertinent to a mailbox h/w IP block.
This enables the support for having multiple instances of
the same h/w IP block in the SoC. This is in preparation
to support the DRA7 SoC, which is the first SoC in the OMAP
family to have multiple mailbox IP instances.

The changes include enhancements to the sub-mailbox registration
logic and mbox startup sequencing, removing the usage of single
global configuration variables for all h/w instances, and storing
the registered sub-mailboxes with the parent mailbox device
structure.

be3322eb70 mailbox/omap: remove the private mailbox structure
The structure omap_mbox_priv is used previously to store arch
specific (OMAP1 vs OMAP2+) data, and is no longer required to be
maintained separately. Instead, absorb its elements into either
the sub-mailbox device structure, omap_mbox, or the individual
fifo descriptor structure, omap_mbox_fifo.

The newmsg_bit and notfull_bit used on Rx and Tx fifos respectively
are represented by the new intr_bit field in the fifo descriptor
structure. The interrupt configuration registers are also moved
into the fifo descriptor structure to allow the Rx and Tx fifos
to use different interrupt lines/users.

5040f53438 mailbox/omap: consolidate OMAP mailbox driver
There is no need for a separate common OMAP mailbox module
now that the OMAP1 mailbox driver has been removed. So,
consolidate the two individual OMAP mailbox modules into a
single driver. This streamlines the driver for converting
to mailbox framework.

The following are the main changes:
- collapse mailbox-omap2.c into omap-mailbox.c
- remove omap_mbox_ops and replace the ops calls with
  the equivalent functionality.
- simplify the sub-mailbox startup/shutdown functionality,
  the one-time operations are moved into probe, and the
  pm_runtime_get_sync and pm_runtime_put_sync can be invoked
  without using a configuration counter.
- move all definitions from private omap_mbox.h into the
  source code, and eliminate this internal header.
- rename some variables that used the omap2_mbox prefix with
  a generic omap_mbox prefix.

e1e4528f8c hwspinlock/omap: enable module before reading SYSSTATUS register
The number of hwspinlocks are determined based on the value read
from the IP block's SYSSTATUS register. However, the module may
not be enabled and clocked, and the read may result in a bus error.

This particular issue is seen rather easily on AM33XX, since the
module wakeup is software controlled, and it is disabled out of
reset. Make sure the module is enabled and clocked before reading
the SYSSTATUS register.

d937678ab6 ARM: dts: Revert enabling of twl configuration for n900
Commit 9188883fd6 (ARM: dts: Enable twl4030 off-idle configuration
for selected omaps) allowed n900 to cut off core voltages during
off-idle. This however caused a regression where twl regulator
vaux1 was not getting enabled for the LCD panel as we are not
requesting it for the panel.

Turns out quite a few devices on n900 are using vaux1, and we need
to either stop idling it, or add proper regulator_get calls for all
users. But until we have a proper solution implemented and tested,
let's just disable the twl off-idle configuration for now for n900.

04ca6973f7 ip: make IP identifiers less predictable
In "Counting Packets Sent Between Arbitrary Internet Hosts", Jeffrey and
Jedidiah describe ways exploiting linux IP identifier generation to
infer whether two machines are exchanging packets.

With commit 73f156a6e8 ("inetpeer: get rid of ip_id_count"), we
changed IP id generation, but this does not really prevent this
side-channel technique.

This patch adds a random amount of perturbation so that IP identifiers
for a given destination [1] are no longer monotonically increasing after
an idle period.

Note that prandom_u32_max(1) returns 0, so if generator is used at most
once per jiffy, this patch inserts no hole in the ID suite and do not
increase collision probability.

This is jiffies based, so in the worst case (HZ=1000), the id can
rollover after ~65 seconds of idle time, which should be fine.

We also change the hash used in __ip_select_ident() to not only hash
on daddr, but also saddr and protocol, so that ICMP probes can not be
used to infer information for other protocols.

For IPv6, adds saddr into the hash as well, but not nexthdr.

If I ping the patched target, we can see ID are now hard to predict.

21:57:11.008086 IP (...)
    A > target: ICMP echo request, seq 1, length 64
21:57:11.010752 IP (... id 2081 ...)
    target > A: ICMP echo reply, seq 1, length 64

21:57:12.013133 IP (...)
    A > target: ICMP echo request, seq 2, length 64
21:57:12.015737 IP (... id 3039 ...)
    target > A: ICMP echo reply, seq 2, length 64

13e9b9972f tipc: make tipc_buf_append() more robust
As per comment from David Miller, we try to make the buffer reassembly
function more resilient to user errors than it is today.

- We check that the "*buf" parameter always is set, since this is
  mandatory input.

- We ensure that *buf->next always is set to NULL before linking in
  the buffer, instead of relying of the caller to have done this.

- We ensure that the "tail" pointer in the head buffer's control
  block is initialized to NULL when the first fragment arrives.

545469f7a5 neighbour : fix ndm_type type error issue
ndm_type means L3 address type, in neighbour proxy and vxlan, it's RTN_UNICAST.
NDA_DST is for netlink TLV type, hence it's not right value in this context.

====================
pull request: wireless-next 2014-07-25

Please pull this batch of updates intended for the 3.17 stream!

For the mac80211 bits, Johannes says:

"We have a lot of TDLS patches, among them a fix that should make hwsim
tests happy again. The rest, this time, is mostly small fixes."

For the Bluetooth bits, Gustavo says:

"Some more patches for 3.17. The most important change here is the move of
the 6lowpan code to net/6lowpan. It has been agreed with Davem that this
change will go through the bluetooth tree. The rest are mostly clean up and
fixes."

and,

"Here follows some more patches for 3.17. These are mostly fixes to what
we've sent to you before for next merge window."

For the iwlwifi bits, Emmanuel says:

"I have the usual amount of BT Coex stuff. Arik continues to work
on TDLS and Ariej contributes a few things for HS2.0. I added a few
more things to the firmware debugging infrastructure. Eran fixes a
small bug - pretty normal content."

And for the Atheros bits, Kalle says:

"For ath6kl me and Jessica added support for ar6004 hw3.0, our latest
version of ar6004.

For ath10k Janusz added a printout so that it's easier to check what
ath10k kconfig options are enabled. He also added a debugfs file to
configure maximum amsdu and ampdu values. Also we had few fixes as
usual."

On top of that is the usual large batch of various driver updates --
brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action.
Rafał has also been very busy with b43 and related updates.

Also, I pulled the wireless tree into this in order to resolve a
merge conflict...

P.S.  The change to fs/compat_ioctl.c reflects a name change in a
Bluetooth header file...

8266f5fcf0 sunvnet: only use connected ports when sending
The sunvnet driver doesn't check whether or not a port is connected when
transmitting packets, which results in failures if a port fails to connect
(e.g., due to a version mismatch). The original code also assumes
unnecessarily that the first port is up and a switch, even though there is
a flag for switch ports.

This patch only matches a port if it is connected, and otherwise uses the
switch_port flag to send the packet to a switch port that is up.

a67eed571a bonding: fix a memory leak in bond_arp_send_all()
This test is reversed so the memory is always leaked.  It's better style
to remove the test anyway.

====================
pull-request: can 2014-07-25

this is a pull request of one patch for the net tree, hoping to get into the
3.16 release.

The patch by George Cherian fixes a regression in the c_can platform driver.
When using two interfaces the regression leads to a non function second
interface.

0f7d83e85d PM / Hibernate: Touch Soft Lockup Watchdog in rtree_next_node
When a memory bitmap is fully populated on a large memory
machine (several TB of RAM) it can take more than a minute
to walk through all bits. This causes the soft lockup
detector on these machine to report warnings.

Avoid this by touching the soft lockup watchdog in the
memory bitmap walking code.
