f079fa005a ixgbe: add flow control ethertype to the anti-spoofing filter
This patch makes sure that flow control packets initiated by the VF are
dropped and reported as spoofed.

Flow control packets can be used to limit the throughput or as DOS
attack when generated from a VF. Flow control is not supported per VF
hence any pause frames generated from a VF are considered malicious.

Also cleaned up indentation and some redundant comments.

fc72dbce09 i40e/i40evf: Refactor PHY structure and add phy_capabilities enum
Remove unused members in the PHY structure and add a new member to store
all the capabilities the PHY has as reported by the FW. This information
will help us determine what speeds the device is capable of when link is
down.

Also add an enum to decode the PHY types the NVM is capable of.
Use the phy_types variable to determine what phy types are possible
when link is down instead of device id as it will be more accurate.

When on a backplane device, we do not support changing any settings,
however we should display all the phy_types we are capable of so if we
see a backplane dev ID set supported and advertised purely based on
the phy_types variable.

0a862b43ac i40e/i40evf: Add module_types and update_link_info
Add a module_types variable to the link_info struct to save the module
information from get_phy_capabilities. This information can be used to
determine which speeds the module supports.

Also add a new function update_link_info which updates the module_types
parameter and then calls get_link_info. This function should be called
in place of get_link_info so that the module_types variable stays
up-to-date with the rest of the link information.

The EAS table does not reflect the values that are actually returned,
so instead, basing these values on the Ethernet compliance codes
specified in table 33 of SFF-8436 as these have been accurate.

Use the new variable in ethtool to differentiate between a 10G/1G dual
speed fiber module and a 10G only module.

21be99ec4e i40e: don't panic on VSI allocation failure
In some circumstances, the firmware may fail to allocate a VSI for a VF.
When this happens, the driver does not react well to the bad news and
has a panic attack.

To fix this problem, check the return value from i40e_alloc_vf_res and
don't try to configure the device further if it failed. Additionally,
explicitly clear the INIT bit when we free VF resources, so that this
bit will be in the proper state in the failure case, and won't blow up
elsewhere.

14e52ee26b i40evf: properly handle ndo_set_mac_address calls
The driver was not correctly handling calls to its ndo_set_mac_address
method. It did not properly check to see if the override would be
allowed by the PF driver, and never removed the old address from its
filter list.

Add a new flag to the adapter struct which is set if the MAC address is
assigned by the PF. Check this flag and don't allow the MAC address to
be changed if it is set. Search for and properly remove the filter
for the old MAC address when the new one is set.

dc6c5fb3b5 btrfs: fix use after free iterating extrefs
The code for btrfs inode-resolve has never worked properly for
files with enough hard links to trigger extrefs.  It was trying to
get the leaf out of a path after freeing the path:

	btrfs_release_path(path);
	leaf = path->nodes[0];
	item_size = btrfs_item_size_nr(leaf, slot);

The fix here is to use the extent buffer we cloned just a little higher
up to avoid deadlocks caused by using the leaf in the path.

At the moment this means only the 'limit' filter, but we're going to add
a few more soon so it's better to have that fixed. Also in older stable
kernels so that it works with newer userspace tools.

4bdc3d6614 tcp/dccp: fix behavior of stale SYN_RECV request sockets
When a TCP/DCCP listener is closed, its pending SYN_RECV request sockets
become stale, meaning 3WHS can not complete.

But current behavior is wrong :
incoming packets finding such stale sockets are dropped.

We need instead to cleanup the request socket and perform another
lookup :
- Incoming ACK will give a RST answer,
- SYN rtx might find another listener if available.
- We expedite cleanup of request sockets and old listener socket.

a98f1b78ec PM / Domains: Fix validation of latency constraints in genpd governor
Commit ba2bbfbf63 (PM / Domains: Remove intermediate states from the
power off sequence) changed the power off sequence in genpd. That also
required some updates regarding the validation of latency constraints in
the genpd governor. Unfortunate that wasn't covered, so let's fix this.

From a runtime PM and latency point of view, we need to consider the worst
case scenario while validating latency constraints. That's typically when
a call to pm_runtime_get_sync() needs to wait for a ongoing runtime
suspend operation to be carried out, as it then also needs to wait for the
device to be runtime resumed again.

The above mentioned commit made the genpd governor's ->stop_ok() callback
responsible of validating genpd's device's runtime suspend/resume latency.
In other words, the constraint needs to be validated towards the relevant
latencies present in genpd's ->runtime_suspend|resume() callbacks.

Earlier, that included latencies from the ->stop|start() callbacks, but as
->save|restore_state() are now also being invoked from genpd's
->runtime_suspend|resume() and to comply with the worst case scenario,
let's take also those latencies into account.

in userspace since commit b74a07beed, "KVM: Remove kernel-allocated
memory regions", 2010-06-21); that is a nice bonus.

1d8007bdee KVM: x86: build kvm_userspace_memory_region in x86_set_memory_region
The next patch will make x86_set_memory_region fill the
userspace_addr.  Since the struct is not used untouched
anymore, it makes sense to build it in x86_set_memory_region
directly; it also simplifies the callers.

ba61a8d9d7 can: avoid using timeval for uapi
The can subsystem communicates with user space using a bcm_msg_head
header, which contains two timestamps. This is problematic for
multiple reasons:

a) The structure layout is currently incompatible between 64-bit
   user space and 32-bit user space, and cannot work in compat
   mode (other than x32).

b) The timeval structure layout will change in 32-bit user
   space when we fix the y2038 overflow problem by redefining
   time_t to 64-bit, making new 32-bit user space incompatible
   with the current kernel interface.
   Cars last a long time and often use old kernels, so the actual
   users of this code are the most likely ones to migrate to y2038
   safe user space.

This tries to work around part of the problem by changing the
publicly visible user interface in the header, but not the binary
interface. Fortunately, the values passed around in the structure
are relative times and do not actually suffer from the y2038
overflow, so 32-bit is enough here.

We replace the use of 'struct timeval' with a newly defined
'struct bcm_timeval' that uses the exact same binary layout
as before and that still suffers from problem a) but not problem
b).

The downside of this approach is that any user space program
that currently assigns a timeval structure to these members
rather than writing the tv_sec/tv_usec portions individually
will suffer a compile-time error when built with an updated
kernel header. Fixing this error makes it work fine with old
and new headers though.

We could address problem a) by using '__u32' or 'int' members
rather than 'long', but that would have a more significant
downside in also breaking support for all existing 64-bit user
binaries that might be using this interface, which is likely
not acceptable.

cannot be exported as is.  Unfortunately some ahash drivers did
not provide them and end up causing crashes with algif_hash.

This patch adds a check to prevent these drivers from registering

====================
bridge: vlan: cleanups & fixes (part 3)

Patch 01 converts the vlgrp member to use rcu as it was already used in a
similar way so better to make it official and use all the available RCU
instrumentation. Patch 02 fixes a bug where the vlan_list can be traversed
without rtnl or rcu held which could lead to using freed entries.
Patch 03 removes some redundant code that isn't needed anymore.
Patch 04 fixes a bug reported by Ido Schimmel about the vlan_flush order
and switchdevs, it moves it back.

v2: patch 03 and 04 are new, couldn't escape the second synchronize_rcu()
since the rhtable destruction can sleep

f409d0ed87 bridge: vlan: move back vlan_flush
Ido Schimmel reported a problem with switchdev devices because of the
order change of del_nbp operations, more specifically the move of
nbp_vlan_flush() which deletes all vlans and frees vlgrp after the
rx_handler has been unregistered. So in order to fix this move
vlan_flush back where it was and make it destroy the rhtable after
NULLing vlgrp and waiting a grace period to make sure noone can see it.

907b1e6e83 bridge: vlan: use proper rcu for the vlgrp member
The bridge and port's vlgrp member is already used in RCU way, currently
we rely on the fact that it cannot disappear while the port exists but
that is error-prone and we might miss places with improper locking
(either RCU or RTNL must be held to walk the vlan_list). So make it
official and use RCU for vlgrp to catch offenders. Introduce proper vlgrp
accessors and use them consistently throughout the code.

====================
net: VRF support in IPv6 stack

Initial support for VRF in IPv6 stack. Makes IPv6 functionality on par
with IPv4 -- ping, tcp client/server and udp client/server all work fine.
tcpdump on vrf device and external tap (e.g., host side tap device) shows
all packets with proper addresses. IPv6 does not need the source address
operation like IPv4. Verified vti6 works properly in my setup as does use
of an IPv6 address on the VRF device.

v3
- re-based to top of net-next (updates per net namespace changes by Eric)
- fixed dst_entry typecasts as requested by Dave
- added flags to inet6_rtm_getroute (IPv6 version of deaa0a6a93)

v2
- fixed CONFIG_IPV6 dependency as questioned by Cong
  - if IPV6 is a module, kbuild ensures VRF is a module
  - if IPV6 is disabled IPV6 functionality is compiled out of VRF module
- addressed comments from Nik over IRC
  - removed duplicate call to netif_is_l3_master in l3mdev_rt6_dst_by_oif
  - changed allocation flag from GFP_ATOMIC to GFP_KERNEL since it is init time
  - added free of rt6i_pcpu
  - check_ipv6_frame returns false only if packet is NDISC type
