Add the ability to set/clear labels assigned to a conntrack
via ctnetlink.
To allow userspace to only alter specific bits, Pablo suggested to add
a new CTA_LABELS_MASK attribute:
The new set of active labels is then determined via
active = (active & ~mask) ^ changeset
i.e., the mask selects those bits in the existing set that should be
changed.
This follows the same method already used by MARK and CONNMARK targets.
Omitting CTA_LABELS_MASK is the same as setting all bits in CTA_LABELS_MASK
to 1: The existing set is replaced by the one from userspace.

similar to connmarks, except labels are bit-based; i.e.
all labels may be attached to a flow at the same time.
Up to 128 labels are supported. Supporting more labels
is possible, but requires increasing the ct offset delta
from u8 to u16 type due to increased extension sizes.
Mapping of bit-identifier to label name is done in userspace.
The extension is enabled at run-time once "-m connlabel" netfilter
rules are added.

Most SIP devices use a source port of 5060/udp on SIP requests, so the
response automatically comes back to port 5060:
phone_ip:5060 -> proxy_ip:5060 REGISTER
proxy_ip:5060 -> phone_ip:5060 100 Trying
The newer Cisco IP phones, however, use a randomly chosen high source
port for the SIP request but expect the response on port 5060:
phone_ip:49173 -> proxy_ip:5060 REGISTER
proxy_ip:5060 -> phone_ip:5060 100 Trying
Standard Linux NAT, with or without nf_nat_sip, will send the reply back
to port 49173, not 5060:
phone_ip:49173 -> proxy_ip:5060 REGISTER
proxy_ip:5060 -> phone_ip:49173 100 Trying
But the phone is not listening on 49173, so it will never see the reply.
This patch modifies nf_*_sip to work around this quirk by extracting
the SIP response port from the Via: header, iff the source IP in the
packet header matches the source IP in the SIP request.

Increase the amount of memory usage limits for incomplete
IP fragments.
Arguing for new thresh high/low values:
High threshold = 4 MBytes
Low threshold = 3 MBytes
The fragmentation memory accounting code, tries to account for the
real memory usage, by measuring both the size of frag queue struct
(inet_frag_queue (ipv4:ipq/ipv6:frag_queue)) and the SKB's truesize.
We want to be able to handle/hold-on-to enough fragments, to ensure
good performance, without causing incomplete fragments to hurt
scalability, by causing the number of inet_frag_queue to grow too much
(resulting longer searches for frag queues).
For IPv4, how much memory does the largest frag consume.
Maximum size fragment is 64K, which is approx 44 fragments with
MTU(1500) sized packets. Sizeof(struct ipq) is 200. A 1500 byte
packet results in a truesize of 2944 (not 2048 as I first assumed)
(44*2944)+200 = 129736 bytes
The current default high thresh of 262144 bytes, is obviously
problematic, as only two 64K fragments can fit in the queue at the
same time.
How many 64K fragment can we fit into 4 MBytes:
4*2^20/((44*2944)+200) = 32.34 fragment in queues
An attacker could send a separate/distinct fake fragment packets per
queue, causing us to allocate one inet_frag_queue per packet, and thus
attacking the hash table and its lists.
How many frag queue do we need to store, and given a current hash size
of 64, what is the average list length.
Using one MTU sized fragment per inet_frag_queue, each consuming
(2944+200) 3144 bytes.
4*2^20/(2944+200) = 1334 frag queues -> 21 avg list length
An attack could send small fragments, the smallest packet I could send
resulted in a truesize of 896 bytes (I'm a little surprised by this).
4*2^20/(896+200) = 3827 frag queues -> 59 avg list length
When increasing these number, we also need to followup with
improvements, that is going to help scalability. Simply increasing
the hash size, is not enough as the current implementation does not
have a per hash bucket locking.

(ipv4: Don't use the cached pmtu informations for input routes)
during times when we cached the pmtu informations on the

Commit 299b0767 (ipv6: Fix IPsec slowpath fragmentation problem)
has introduced a error in the header length calculation that
provokes corrupted packets when non-fragmentable extensions
headers (Destination Option or Routing Header Type 2) are used.
rt->rt6i_nfheader_len is the length of the non-fragmentable
extension header, and it should be substracted to
rt->dst.header_len, and not to exthdrlen, as it was done before
commit 299b0767.
This patch reverts to the original and correct behavior. It has
been successfully tested with and without IPsec on packets
that include non-fragmentable extensions headers.

While a privileged program can open a raw socket, attach some
restrictive filter and drop its privileges (or send the socket to an
unprivileged program through some Unix socket), the filter can still
be removed or modified by the unprivileged program. This commit adds a
socket option to lock the filter (SO_LOCK_FILTER) preventing any
modification of a socket filter program.
This is similar to OpenBSD BIOCLOCK ioctl on bpf sockets, except even
root is not allowed change/drop the filter.
The state of the lock can be read with getsockopt(). No error is
triggered if the state is not changed. -EPERM is returned when a user
tries to remove the lock or to change/remove the filter while the lock
is active. The check is done directly in sk_attach_filter() and
sk_detach_filter() and does not affect only setsockopt() syscall.

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

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

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 flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

Eric Dumazet pointed out that act_mirred needs to find the current net_ns,
and struct net pointer is not provided in the call chain. His original
patch made use of current->nsproxy->net_ns to find the network namespace,
but this fails to work correctly for userspace code that makes use of
netlink sockets in different network namespaces. Instead, pass the
"struct net *" down along the call chain to where it is needed.
This version removes the ifb changes as Eric has submitted that patch
separately, but is otherwise identical to the previous version.

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."

The only user is cxgb3 driver.
old_neigh is used to check device change, but it must not happen
on redirect. In this sense, we can remove old_neigh argument.

Pull networking fixes from David Miller:
1) Fix regression allowing IP_TTL setting of zero, fix from Cong Wang.
2) Fix leak regressions in tunap, from Jason Wang.
3) be2net driver always returns IRQ_HANDLED in INTx handler, fix from
Sathya Perla.
4) qlge doesn't really support NETIF_F_TSO6, don't set that flag. Fix
from Amerigo Wang.
5) Add 802.11ad Atheros wil6210 driver, from Vladimir Kondratiev.
6) Fix MTU calculations in mac80211 layer, from T Krishna Chaitanya.
7) Station info layer of mac80211 needs to use del_timer_sync(), from
Johannes Berg.
8) tcp_read_sock() can loop forever, because we don't immediately stop
when recv_actor() returns zero. Fix from Eric Dumazet.
9) Fix WARN_ON() in tcp_cleanup_rbuf(). We have to use sk_eat_skb() in
tcp_recv_skb() to handle the case where a large GRO packet is split
up while it is use by a splice() operation. Fix also from Eric
Dumazet.
10) addrconf_get_prefix_route() in ipv6 tests flags incorrectly, it
does:
if (X && (p->flags & Y) != 0)
when it really meant to go:
if (X && (p->flags & X) != 0)
fix from Romain Kuntz.
11) Fix lost Kconfig dependency for bfin_mac driver hardware
timestamping. From Lars-Peter Clausen.
12) Fix regression in handling of RST without ACK in TCP, from Eric
Dumazet.

Router Alert option is very small and we can store the value
itself in the skb.
