afd465030a net: ipv4: Standardize prefixes for message logging
Add #define pr_fmt(fmt) as appropriate.

Add "IPv4: ", "TCP: ", and "IPsec: " to appropriate files.
Standardize on "UDPLite: " for appropriate uses.
Some prefixes were previously "UDPLITE: " and "UDP-Lite: ".

Add KBUILD_MODNAME ": " to icmp and gre.
Remove embedded prefixes as appropriate.

Add missing "\n" to pr_info in gre.c.

058bd4d2a4 net: Convert printks to pr_<level>
Use a more current kernel messaging style.

Convert a printk block to print_hex_dump.
Coalesce formats, align arguments.
Use %s, __func__ instead of embedding function names.

Some messages that were prefixed with <foo>_close are
now prefixed with <foo>_fini.  Some ah4 and esp messages
are now not prefixed with "ip ".

The intent of this patch is to later add something like
  #define pr_fmt(fmt) "IPv4: " fmt.
to standardize the output messages.

Text size is trivially reduced. (x86-32 allyesconfig)

43db362d3a net: get rid of some pointless casts to sockaddr
The following 4 functions:
  move_addr_to_kernel
  move_addr_to_user
  verify_iovec
  verify_compat_iovec
are always effectively called with a sockaddr_storage.

Make this explicit by changing their signature.

This removes a large number of casts from sockaddr_storage to sockaddr.

8b2aaedee4 ipv6: Fix Smatch warning.
With commit d6ddef9e641d(IPv6: Fix not join all-router mcast group
when forwarding set.) I check 'dev' after it's dereference that
leads to a Smatch complaint:

net/ipv6/addrconf.c:438 ipv6_add_dev()
	 warn: variable dereferenced before check 'dev' (see line 432)

net/ipv6/addrconf.c
   431		/* protected by rtnl_lock */
   432		rcu_assign_pointer(dev->ip6_ptr, ndev);
                                   ^^^^^^^^^^^^
Old dereference.

   433
   434		/* Join all-node multicast group */
   435		ipv6_dev_mc_inc(dev, &in6addr_linklocal_allnodes);
   436
   437		/* Join all-router multicast group if forwarding is set

   438		if (ndev->cnf.forwarding && dev && (dev->flags &
IFF_MULTICAST))
                                            ^^^

Remove the check to avoid the complaint as 'dev' can't be NULL.

fdde0a26a2 Bluetooth: Set security level on incoming pairing request
If a master would like to raise the security level, it will send a
pairing request. While the pending security level is set on an incoming
security request (from a slave), it is not set on a pairing request. As
a result, the security level would not be raised on the slave in such
case.

Fix this by setting the pending security when receiving pairing
requests according to the requested authorization.

81e5d41d7e openvswitch: Fix checksum update for actions on UDP packets.
When modifying IP addresses or ports on a UDP packet we don't
correctly follow the rules for unchecksummed packets.  This meant
that packets without a checksum can be given a incorrect new checksum
and packets with a checksum can become marked as being unchecksummed.
This fixes it to handle those requirements.

fcff4f108d mac80211: Filter duplicate IE ids
mac80211 is lenient with respect to reception of corrupted beacons.
Even if the frame is corrupted as a whole, the available IE elements
are still passed back and accepted, sometimes replacing legitimate
data.  It is unknown to what extent this "feature" is made use of,
but it is clear that in some cases, this is detrimental.  One such
case is reported in http://crosbug.com/26832 where an AP corrupts
its beacons but not its probe responses.

One approach would be to completely reject frames with invaid data
(for example, if the last tag extends beyond the end of the enclosing
PDU).  The enclosed approach is much more conservative: we simply
prevent later IEs from overwriting the state from previous ones.
This approach hopes that there might be some salient data in the
IE stream before the corruption, and seeks to at least prevent that
data from being overwritten.  This approach will fix the case above.

Further, we flag element structures that contain data we think might
be corrupted, so that as we fill the mac80211 BSS structure, we try
not to replace data from an un-corrupted probe response with that
of a corrupted beacon, for example.

Short of any statistics gathering in the various forms of AP breakage,
it's not possible to ascertain the side effects of more stringent
discarding of data.

24de58f465 netfilter: xt_CT: allow to attach timeout policy + glue code
This patch allows you to attach the timeout policy via the
CT target, it adds a new revision of the target to ensure
backward compatibility. Moreover, it also contains the glue
code to stick the timeout object defined via nfnetlink_cttimeout
to the given flow.

Example usage (it requires installing the nfct tool and
libnetfilter_cttimeout):

1) create the timeout policy:

 nfct timeout add tcp-policy0 inet tcp \
	established 1000 close 10 time_wait 10 last_ack 10

2) attach the timeout policy to the packet:

 iptables -I PREROUTING -t raw -p tcp -j CT --timeout tcp-policy0

You have to install the following user-space software:

a) libnetfilter_cttimeout:
   git://git.netfilter.org/libnetfilter_cttimeout

b) nfct:
   git://git.netfilter.org/nfct

You also have to get iptables with -j CT --timeout support.

417e02bf42 netfilter: xt_LOG: fix bogus extra layer-4 logging information
In 16059b5 netfilter: merge ipt_LOG and ip6_LOG into xt_LOG, we have
merged ipt_LOG and ip6t_LOG.

However:

IN=wlan0 OUT= MAC=xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
SRC=213.150.61.61 DST=192.168.1.133 LEN=40 TOS=0x00 PREC=0x00 TTL=117
ID=10539 DF PROTO=TCP SPT=80 DPT=49013 WINDOW=0 RES=0x00 ACK RST
URGP=0 PROTO=UDPLITE SPT=80 DPT=49013 LEN=45843 PROTO=ICMP TYPE=0
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Several missing break in the code led to including bogus layer-4
information. This patch fixes this problem.

544d5c7d9f netfilter: ctnetlink: allow to set expectfn for expectations
This patch allows you to set expectfn which is specifically used
by the NAT side of most of the existing conntrack helpers.

I have added a symbol map that uses a string as key to look up for
the function that is attached to the expectation object. This is
the best solution I came out with to solve this issue.

This patch allow you to set the helper for newly created
expectations based of the CTA_EXPECT_HELP_NAME attribute.
