Andrey Vagin 51d7cccf07 net: make sock diag per-namespace
Before this patch sock_diag works for init_net only and dumps
information about sockets from all namespaces.

This patch expands sock_diag for all name-spaces.
It creates a netlink kernel socket for each netns and filters
data during dumping.

v2: filter accoding with netns in all places
    remove an unused variable.

Eric Dumazet a6df1ae938 tcp: add OFO snmp counters
Add three SNMP TCP counters, to better track TCP behavior
at global stage (netstat -s), when packets are received
Out Of Order (OFO)

TCPOFOQueue : Number of packets queued in OFO queue

TCPOFODrop  : Number of packets meant to be queued in OFO
              but dropped because socket rcvbuf limit hit.

TCPOFOMerge : Number of packets in OFO that were merged with
              other packets.

Steffen Klassert 141e369de6 xfrm: Initialize the struct xfrm_dst behind the dst_enty field
We start initializing the struct xfrm_dst at the first field
behind the struct dst_enty. This is error prone because it
might leave a new field uninitialized. So start initializing
the struct xfrm_dst right behind the dst_entry.

David S. Miller 921a678cb6 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John Linville says:

====================
Several drivers see updates: mwifiex, ath9k, iwlwifi, brcmsmac,
wlcore/wl12xx/wl18xx, and a handful of others.  The bcma bus got a
lot of attention from Hauke Mehrtens.  The cfg80211 component gets
a flurry of patches for multi-channel support, and the mac80211
component gets the first few VHT (11ac) and 60GHz (11ad) patches.
This also includes the removal of the iwmc3200 drivers, since the
hardware never became available to normal people.

Additionally, the NFC subsystem gets a series of updates.  According to
Samuel, "Here are the interesting bits:

- A better error management for the HCI stack.
- An LLCP "late" binding implementation for a better NFC SAP usage. SAPs are
  now reserved only when there's a client for it.
- Support for Sony RC-S360 (a.k.a. PaSoRi) pn533 based dongle. We can read and
  write NFC tags and also establish a p2p link with this dongle now.
- A few LLCP fixes."

Finally, this includes another pull of the fixes from the wireless
tree in order to resolve some merge issues.

David S. Miller 85b91b0339 ipv4: Don't store a rule pointer in fib_result.
We only use it to fetch the rule's tclassid, so just store the
tclassid there instead.

This also decreases the size of fib_result by a full 8 bytes on
64-bit.  On 32-bits it's a wash.

Alexander Duyck 540eb7bf0b net: Update alloc frag to reduce get/put page usage and recycle pages
This patch is meant to help improve performance by reducing the number of
locked operations required to allocate a frag on x86 and other platforms.
This is accomplished by using atomic_set operations on the page count
instead of calling get_page and put_page.  It is based on work originally
provided by Eric Dumazet.

In addition it also helps to reduce memory overhead when using TCP.  This
is done by recycling the page if the only holder of the frame is the
netdev_alloc_frag call itself.  This can occur when skb heads are stolen by
either GRO or TCP and the driver providing the packets is using paged frags
to store all of the data for the packets.
