This patch adds anti-spoofing checks in sit.c as specified in RFC3964
section 5.2 for 6to4 and RFC5969 section 12 for 6rd. I left out the
checks which could easily be implemented with netfilter.
Specifically this patch adds following logic (based loosely on the
pseudocode in RFC3964 section 5.2):
if prefix (inner_src_v6) == rd6_prefix (2002::/16 is the default)
and outer_src_v4 != embedded_ipv4 (inner_src_v6)
drop
if prefix (inner_dst_v6) == rd6_prefix (or 2002::/16 is the default)
and outer_dst_v4 != embedded_ipv4 (inner_dst_v6)
drop
accept
To accomplish the specified security checks proposed by above RFCs,
it is still necessary to employ uRPF filters with netfilter. These new
checks only kick in if the employed addresses are within the 2002::/16 or
another range specified by the 6rd-prefix (which defaults to 2002::/16).

When attempting to build linux-next with user namespaces enabled I ran
into this fun build error.
CC net/ipv6/inet6_connection_sock.o

Using kuid_t instead of int to hold the uid fixes this.

A GRE tunnel can be configured so that outgoing tunnel packets inherit
the value of the TOS field from the inner IP header. In doing so, when
a non-IP packet is transmitted through the tunnel, the TOS field will
always be set to 0.
Instead, the user should be able to configure a different TOS value as
the fallback to use for non-IP packets. This is helpful when the non-IP
packets are all control packets and should be handled by routers outside
the tunnel as having Internet Control precedence. One example of this is
the NHRP packets that control a DMVPN-compatible mGRE tunnel; they are
encapsulated directly by GRE and do not contain an inner IP header.
Under the existing behavior, the IFLA_GRE_TOS parameter must be set to
'1' for the TOS value to be inherited. Now, only the least significant
bit of this parameter must be set to '1', and when a non-IP packet is
sent through the tunnel, the upper 6 bits of this same parameter will be
copied into the TOS field. (The ECN bits get masked off as before.)
This behavior is backwards-compatible with existing configurations and
iproute2 versions.

There are some usecase when lifetime of ipv4 addresses might be helpful.
For example:
1) initramfs networkmanager uses a DHCP daemon to learn network
configuration parameters
2) initramfs networkmanager addresses, routes and DNS configuration
3) initramfs networkmanager is requested to stop
4) initramfs networkmanager stops all daemons including dhclient
5) there are addresses and routes configured but no daemon running. If
the system doesn't start networkmanager for some reason, addresses and
routes will be used forever, which violates RFC 2131.
This patch is essentially a backport of ivp6 address lifetime mechanism
for ipv4 addresses.
Current "ip" tool supports this without any patch (since it does not
distinguish between ipv4 and ipv6 addresses in this perspective.
Also, this should be back-compatible with all current netlink users.

Updating the fragmentation queues LRU (Least-Recently-Used) list,
required taking the hash writer lock. However, the LRU list isn't
tied to the hash at all, so we can use a separate lock for it.

Replace the per network namespace shared atomic "mem" accounting
variable, in the fragmentation code, with a lib/percpu_counter.
Getting percpu_counter to scale to the fragmentation code usage
requires some tweaks.
At first view, percpu_counter looks superfast, but it does not
scale on multi-CPU/NUMA machines, because the default batch size
is too small, for frag code usage. Thus, I have adjusted the
batch size by using __percpu_counter_add() directly, instead of
percpu_counter_sub() and percpu_counter_add().
The batch size is increased to 130.000, based on the largest 64K
fragment memory usage. This does introduce some imprecise
memory accounting, but its does not need to be strict for this
use-case.
It is also essential, that the percpu_counter, does not
share cacheline with other writers, to make this scale.

This change is primarily a preparation to ease the extension of memory
limit tracking.
The change does reduce the number atomic operation, during freeing of
a frag queue. This does introduce a some performance improvement, as
these atomic operations are at the core of the performance problems
seen on NUMA systems.

When allocating memory for neighbour cache entry, if
tbl->entry_size is not set, we always calculate
sizeof(struct neighbour) + tbl->key_len, which is common
in the same table.
With this change, set tbl->entry_size during the table
initialization phase, if it was not set, and use it in
neigh_alloc() and neighbour_priv().
This change also allow us to have both of protocol private
data and device priate data at tha same time.
Note that the only user of prototcol private is DECnet
and the only user of device private is ATM CLIP.
Since those are exclusive, we have not been facing issues
here.

I found if we write a larger than 4GB value to some sysctl
variables, the sending syscall will hang up forever, because these
variables are 32 bits, such large values make them overflow to 0 or
negative.
This patch try to fix overflow or prevent from zero value setup
of below sysctl variables:
net.core.wmem_default
net.core.rmem_default
net.core.rmem_max
net.core.wmem_max
net.ipv4.udp_rmem_min
net.ipv4.udp_wmem_min

John W. Linville says:
====================
Included is an NFC pull. Samuel says:
"It brings the following goodies:
- LLCP socket timestamping (To be used e.g with the recently released nfctool
application for a more efficient skb timestamping when sniffing).
- A pretty big pn533 rework from Waldemar, preparing the driver to support
more flavours of pn533 based devices.
- HCI changes from Eric in preparation for the microread driver support.
- Some LLCP memory leak fixes, cleanups and slight improvements.
- pn544 and nfcwilink move to the devm_kzalloc API.
- An initial Secure Element (SE) API.
- An nfc.h license change from the original author, allowing non GPL
application code to safely include it."
Also included are a pair of mac80211 pulls. Johannes says:
"We found two bugs in the previous code, so I'm sending you a pull
request again this soon.
This contains two regulatory bug fixes, some of Thomas's hwsim beacon
timer work and a documentation fix from Bob."
"Another pull request for mac80211-next. This time, I have a number of
things, the patches are mostly self-explanatory. There are a few fixes
from Felix and myself, and random cleanups & improvements. The biggest
thing is the partial patchset from Marco preparing for mesh powersave."
Additionally, there are a pair of iwlwifi pulls. Johannes says:
"For iwlwifi-next, I have a few cleanups/improvements as well as a few
not very important fixes and more preparations for new devices."
"Please pull a few updates for iwlwifi. These are just some cleanups and
a debug improvement."
On top of that, there is a slew of driver updates. This includes
brcmfmac, mwifiex, ath9k, carl9170, and mwl8k as well as a handful
of others. The bcma and ssb busses get some attention as well.
Still, I don't see any big headliners here.
Also included is a pull of the wireless tree, in order to resolve
some merge conflicts.

mac80211: Optimize scans on current operating channel.
we do not disable PS while going back to operational channel (on
ieee80211_scan_state_suspend) and deffer that until scan finish.
But since we are allowed to send frames, we can send a frame to AP
without PM bit set, so disable PS on AP side. Then when we switch
to off-channel (in ieee80211_scan_state_resume) we do not enable PS.
Hence we are off-channel with PS disabled, frames are not buffered
by AP.
To fix remove offchannel_ps_disable argument and always enable PS when
going off-channel and disable it when going on-channel, like it was
before.

During FT roaming, wpa_supplicant attempts to set the
key before association. This used to be rejected, but
as a side effect of my commit 66e67e418908442389d3a9e
("mac80211: redesign auth/assoc") the key was accepted
causing hardware crypto to not be used for it as the
station isn't added to the driver yet.
It would be possible to accept the key and then add it
to the driver when the station has been added. However,
this may run into issues with drivers using the state-
based station adding if they accept the key only after
association like it used to be.
For now, revert to the behaviour from before the auth
and assoc change.

The length parameter should be sizeof(req->name) - 1 because there is no
guarantee that string provided by userspace will contain the trailing
'\0'.
Can be easily reproduced by manually setting req->name to 128 non-zero
bytes prior to ioctl(HIDPCONNADD) and checking the device name setup on
input subsystem:
$ cat /sys/devices/pnp0/00\:04/tty/ttyS0/hci0/hci0\:1/input8/name

("f0:af:f0:af:f0:af" is the device bluetooth address, taken from "phys"

To ease further DFS development regarding interface combinations, use
the interface combinations structure to test for radar capabilities.
Drivers can specify which channel widths they support, and in which
modes. Right now only a single AP interface is allowed, but as the
DFS code evolves other combinations can be enabled.

The NL80211_ATTR_USE_MFP attribute was originally added for
NL80211_CMD_ASSOCIATE, but it is actually as useful (if not even more
useful) with NL80211_CMD_CONNECT, so process that attribute with the
connect command, too.

As per email discussion Jouni Malinen pointed out that:
"P2P message exchanges can be executed on the current operating channel
of any operation (both P2P and non-P2P station). These can be on 5 GHz
and even on 60 GHz (so yes, you _can_ do GO Negotiation on 60 GHz).
As an example, it would be possible to receive a GO Negotiation Request
frame on a 5 GHz only radio and then to complete GO Negotiation on that
band. This can happen both when connected to a P2P group (through client
discoverability mechanism) and when connected to a legacy AP (assuming
the station receive Probe Request frame from full scan in the beginning
of P2P device discovery)."
This means that P2P messages can be sent over different radio devices.
However, these should use the same P2P device address so it should be
able to provision this from user-space. This patch adds a parameter for
this to struct vif_params which should only be used during creation of
the P2P device interface.

Add the nl80211_mesh_power_mode enumeration which holds possible
values for the mesh power mode. These modes are unknown, active,
light sleep and deep sleep.
Add power_mode entry to the mesh config structure to hold the
user-configured default mesh power mode. This value will be used
for new peer links.
Add the dot11MeshAwakeWindowDuration value to the mesh config.
The awake window is a duration in TU describing how long the STA
will stay awake after transmitting its beacon in PS mode.
Add access routines to:
- get/set local link-specific power mode (STA)
- get remote STA's link-specific power mode (STA)
- get remote STA's non-peer power mode (STA)
- get/set default mesh power mode (mesh config)
- get/set mesh awake window duration (mesh config)
All config changes may be done at mesh runtime and take effect
immediately.

When the driver's resume function can't completely
restore the configuration in the device, it returns

restart request, but done directly.
In this case, also call the driver's restart_complete()

Samuel Ortiz <sameo@linux.intel.com> says:
"This is the first NFC patchset targeted at the 3.9 merge window.
It brings the following goodies:
- LLCP socket timestamping (To be used e.g with the recently released nfctool
application for a more efficient skb timestamping when sniffing).
- A pretty big pn533 rework from Waldemar, preparing the driver to support
more flavours of pn533 based devices.
- HCI changes from Eric in preparation for the microread driver support.
- Some LLCP memory leak fixes, cleanups and slight improvements.
- pn544 and nfcwilink move to the devm_kzalloc API.
- An initial Secure Element (SE) API.
- An nfc.h license change from the original author, allowing non GPL
application code to safely include it."

Each NFC adapter can have several links to different secure elements and
that property needs to be exported by the drivers.
A secure element link can be enabled and disabled, and card emulation will
be handled by the currently active one. Otherwise card emulation will be
host implemented.

Some chips diverge from the HCI spec in their implementation of standard
features. This adds a new quirks parameter to
nfc_hci_allocate_device() to let the driver indicate its divergence.

Some chips use a standard HCI event code, destined to a proprietary
gate, with a different meaning. Therefore, the HCI driver must always
have a chance to intercept the event before standard processing is
attempted.
The new semantic specifies that the result value "1" means that the
driver doesn't especially handle the event. result <= 0 means it was
handled.

When an adapter is removed, it will unregister itself from hci and/or
nfc core. In order to do that safely, work tasks must first be canceled
and prevented to be scheduled again, before the hci or nfc device can be
destroyed.

The reference count bump on the llcp Rx path is leading to a memory leak
whenever we're not receiving an I frame.
We fix that by removing the refcount bump (drivers must not free their
received skb) and using it only in the I frame path, when the frame is
actually queued. In that case, the skb will only be freed when someone
fetches it from userspace. in all other cases, LLCP received frames will
be freed when leaving the Rx work queue.
